Dolores Krieger Nuring Theory
Dolores Krieger Therapeutic Touch Takoya Walker College of Coastal Georgia Biography Dolores Krieger, PhD, RN is a Professor Emerita of Nursing Science, New York University, and co-creator of Therapeutic Touch. She is a recognized holistic nursing theorist and pioneering researcher on Therapeutic Touch and the dynamics of healing. At NYU, her course Frontiers of Nursing has been taught since the early 1970's. One of the first nursing theorists to recognize holistic nursing as a viable nursing science, she was an early proponent and initiator of the term, ââ¬Å"The Renaissance Nurse. A member of Sigma Theta Tau, Dr. Krieger created five graduate programs in nursing science during her tenure at New York University. Internationally known, she has traveled extensively around the world presenting her theories, papers, presentations and seminars. With more than 400 professional papers and journal articles to her credit, she has been widely sought after as a radio and television personalit y. Dr Kriegerââ¬â¢s work in Therapeutic Touch has been credited with being the first healing method taught within a university system and the most researched form of hand-on healing to date.Therapeutic Touch is a nursing intervention and considered ââ¬Å"an extension of professional skills. â⬠Numerous doctoral dissertations and graduate studies have originated on Therapeutic Touch. With physicians, nurses and many other healthcare professionals practicing and researching Therapeutic Touch, it has become a widely accepted nursing intervention within our medical institutions. Therapeutic Touch is taught in hundreds of medical centers and universities, and is practiced in over 100 countries worldwide.At last count, Therapeutic Touch had been taught to well over 200,000 healthcare professionals. Besides continuing to write and teach Therapeutic Touch, Dr Krieger is involved in Deep Ecology and lives in a wildlife sanctuary she has created in Montana. (Krieger 2010)à à à à à Significant Accomplishments Dr. Krieger is well known for her Therapeutic Touch theory, which was developed in the early 1970s by Dolores Krieger RN, a professor of nursing.Krieger and co-founder and Dora Kunz stated that the human body is kept alive and vital by a force called prana (a Sanskrit term meaning vital force) and that this energy flows around and through the body and is channeled by chakras, a series of non-physical energy centers in the body. Whereas the original protocol was based on actual physical touch (Krieger, 1975), subsequent research claimed that similar results could be obtained without touching the patient (Quinn, 1982).Current practice is based on the assumption that the physical body is surrounded by an energy field that trained practitioners can detect, assess, and manipulate, and that imbalances in this energy field result in illness or pain, which TT can treat (Krieger ;amp; Kunz, 1989). Any variances or discrepancy can be felt with the hands, w ithout using physical contact and are normally described as a sensation of tingling, pressure, pulling, temperature changes, and energy spikes.Using the Technique A TT session begins with a centering exercise by the practitioner. This step is similar to a brief period of meditation or prayer, it is quieting the mind by focusing the attention, the Therapeutic Touch Practitioner (TTP) focuses within self and prepare to heal. Assessment is the next phase, in this phase the TTP tries to locate any imbalances in the patient's Human Energy Field (HEF).The last phase utilizes several techniques one is called unruffling, the TTP uses circular sweeping motions aiming to ââ¬Å"decongestâ⬠accumulated energy and either redistribute it to areas of lower energy, or rid the HEF of the excess energy by sweeping it down the body and off at the feet, shaking the excess off their hands (a motion similar to shaking water off the fingers) at the foot of the bed or table. (Begley S, 1999) The TTP can also perform Directing just to name a few. Directing is transferring energy between the nurse and client, or from one area of the clientââ¬Ës body to another.The last phase is reassessing the field. In this phase an assessment is made again to determine if ones desired goals were meet. The theory behind the technique Therapeutic Touch relies on four basic assumptions as working hypotheses 1) Humans are open, complex and pandimensional energy systems (Rogers); 2) In a state of health, life energy flows freely through the organism in a balanced, symmetrical manner (Kunz); 3) Human beings are capable of both transformation and transcendence (Krieger); and 4) Healing is an intrinsic movement toward order that occurs in living organisms and can be facilitated by practitioners.Life energy follows the intent to heal (Kunz). Application to Modern Nursing The modern nurse can implement TT has a relaxation method for their patient, which can help rid their bodies of anxiety that so oft en comes as a result of illness. It also would be would be very beneficial in hospice work since it promotes relaxation, reduces anxiety, and often alters a person's perception of pain. Therapeutic Touch can also significantly improve or eradicate the perception of pain. Literary Review Dr.Kriegerââ¬â¢s is the author of 12 books which she published throughout her career: Foundations for Holistic Health Nursing Practices: The Renaissance Nurse; The Therapeutic Touch: How to Use Your Hands to Help or Heal; Accepting Your Power to Heal: The Personal Practice of Therapeutic Touch; The Therapeutic Touch Inner Workbook; Therapeutic Touch as Transpersonal Healing; The Spiritual Dimensions of Therapeutic Touch; Therapeutic Touch: A Book of Readings; and Living the Therapeutic Touch: Healing as a Lifestyle which is her most popular book and have been translated into several languages.Conclusion The Therapeutic Touch theory is another way to offer ones patient a contemporary modality coupl e with traditional medicine or in the absence of it. This theory is a guide that enables the nurse to become one with his or her patient and become the instrument of healing. Therapeutic Touch teaches damaged energy field reflects its ailments in the physical body as ââ¬Å"dis-ease,â⬠not disease normally referred to in the medical terms, but instead itââ¬â¢s just a state of imbalance that alters the natural functioning of the individual.Generally, this results in the weakening of the body, a slowing down of the healing process, and an across the board decline in faculties. TT states we as Therapeutic touch practitioners can then remove the irregularities of the energy field which causes dis-ease, both as a preventative mechanism and as a treatment for manifested illness thereby centering the energies of that person. Summary I must admit Iââ¬â¢m not a full believer of this theory. I do agree that humans carry with them an energy field and I also believe in the biblical l aying on of hands, however in the bible it was the Holy Spirit that healed.Therapeutic touch, in my belief, places us in the rule of the shaman so to speak or Holy Spirit which allows us to move and even heal aliments that sometimes neither the Therapeutic touch practioner nor the client knew they had, which is hard for me to believe. Despite unbelief, my colleagues and I tried to feel this energy that so many have testified to, however I was unable to feel anything no tingling, no pressure, no heat, absolutely nothing.Reference 1.

Motherhood as Vocation
Of Woman Born: Motherhood as Experience and Institution reveals the trials and tribulations of mothers everywhere and across time through the voice and experiences of its author, Adrienne Rich.à This classic piece of feminist literature is an exceptionally relevant work even after the thirty years since its original publication.à Motherhood, as described by Rich, is a ââ¬Å"Sacred Callingâ⬠with a healthy dose of irony.à From this description it is not entirely clear the depth of Rich's personal experience and perception of motherhood.à In reading the book, though, her message of motherhood as a skewed institution becomes entirely clear. Rich describes her experiences in motherhood as being fairly forgettable save for the exception of ââ¬Å"anxiety, physical weariness, anger, self blame, boredom and divisions withinâ⬠herself.à These feelings seem to sum up the experiences of many mothers and, yet, we also often hear of the fine points of mothering, as well.à We hear of the joy in hearing a child's first words.à We hear of the fun in taking a toddler to the park for exploration. Even the trials we hear of regarding the trouble-making teens seem laced with a subtle but happy sentimental reflection.à Rich's reflections on motherhood, though, only seem to fixate on the loneliness, fears and negativity associated with the difficult occupation of motherhood.à Readers are not privileged to the enjoyable aspects of her motherhood experiences.à In fact, readers are made to believe that, perhaps, all motherhood was for Rich was the trials and tribulations. The view of motherhood that readers get from Rich's descriptions is that she feels put upon, oppressed by the institution of motherhood and a part of a culture (motherhood) that is undervalued and under-appreciated.à Yet motherhood is perhaps the most vital institution of all.à So while the integral components of this institution, the mothers, must embark on the grand journey for which they received the sacred calling, they are not justly rewarded but, instead, penalized for participating.à à Therein, perhaps, lies the biggest irony of all: motherhood is the institution that keeps civilization running and, yet, this multifaceted position has become one of the least valued. Throughout history, as Rich sees it, mothers have not received the admiration they are due.à Instead, they have been oppressed and treated as though their roles are to be expected but not appreciated.à In addition to this hegemonically accepted perception of motherhood, women have been made to feel as though their main function as a human being is to reproduce.à Thus, women have been made to feel as though they are only true women through the act of bearing and raising children. At the time of the book's writing, the Women's Movement was in full swing and the sad state of the institution of motherhood had become even more pitiful.à Although women were entering the workforce more and more, mothers were still being treated as second class citizens who were expected to maintain their roles of mother over all else.à But, the situation was becoming even worse.à Now, women were elated to be welcomed (or somewhat welcomed) into the workforce and, yet, they were soon to be expected to take on everything in addition to motherhood! Things have progressively gotten worse for women in the institution of motherhood.à With the Women's Movement and its combining with the established role of motherhood, women have bought in to the ideal that they are, in fact, expected to take on everything.à Women have been allowed to work the long days just like men, but something is different between the sexes: women are still expected to tend to the children and the household just as much as the pre-Women's Movement days. So, really, women are taking on the jobs of at least two people and being sold on the idea that this is the best of both worlds.à Rich's trials took place in the confines of her own household without the added trouble of trying to incorporate her working life.à In Of Woman Born: Motherhood as Experience and Institution, Rich sounds most bothered, in her motherhood experiences, by the boredom of her life and the lack of outside outlets available to her.à That is, Rich's story appears to be one of a bored mother with only her children to focus on.à For someone like Rich who had career aspirations and maybe didn't necessarily even possess the drive to have children, the institution of motherhood only served to hold her back and push her down. The institution of motherhood is one that is certainly oppressive.à I believe it is, as Rich suggests, a means by which patriarchal influences have maintained control over womankind.à However, part of being a mother is the desire to want to mother.à I believe that times have changed somewhat since the time of the writing and more and more women are seeing that they do not have to bear and raise children out of obligation.à Of course, there is the new problem that women feel the need to be Superwomen and do it all, but at least the weight to bear children is a flexible one that can be lifted if desired. Hegemonic ideals will always dominate, but personal choice can have a greater influence if we have faith in ourselves and our roles in life.à Although the institution of motherhood may always be tainted by the facets that serve to oppress mothers everywhere, personal choice can ultimately dictate our place in the world, individual roles of motherhood and the ability to enjoy that role if it is ones true chosen path.

Direct Marketing Essay
Direct marketing is a channel-agnostic form of advertising that allows businesses and nonprofits organizations to communicate straight to the customer, with advertising techniques that can include Cell Phone Text messaging, email, interactive consumer websites, online display ads, fliers, catalog distribution, promotional letters, and outdoor advertising. Direct marketing messages emphasize a focus on the customer, data, and accountability. Characteristics that distinguish direct marketing are: 1. Marketing messages are addressed directly to the customer and/or customers. Direct marketing relies on being able to address the members of a target market. Addressability comes in a variety of forms including email addresses, mobile phone numbers, Web browser cookies, fax numbers and postal addresses. 2. Direct marketing seeks to drive a specific ââ¬Å"call to action.â⬠For example, an advertisement may ask the prospect to call a freephone number or click on a link to a website. 3. Direct marketing emphasizes trackable, measurable responses from customers ââ¬â regardless of medium. Direct marketing is practiced by businesses of all sizes ââ¬â from the smallest start-up to the leaders on the Fortune 500. A well-executed direct advertising campaign can prove a positive return on investment by showing how many potential customers responded to a clear call-to-action. General advertising eschews calls-for-action in favor of messages that try to build prospectsââ¬â¢ emotional awareness or engagement with a brand. Even well-designed general advertisements rarely can prove their impact on the organizationââ¬â¢s bottom line. A recent study by the Direct Marketing Association reports that in 2010, marketers ââ¬â commercial and nonprofit ââ¬â spent $153.3 billion on direct marketing, which accounted for 54.2% of all ad expenditures in the United States. Measured against total US sales, these advertising expenditures generated approximately $1.798 trillion in incremental sales. In 2010, direct marketing accounted for 8.3% of total US gross domestic product. Also in 2010, there were 1.4 million direct marketing employees in the US. Their collective sales efforts directly supported 8.4 million other jobs, accounting for a total of 9.8 million US jobs. Direct marketing is attractive to many marketers because its positive results can be measured directly. For example, if a marketer sends out 1,000 solicitations by mail and 100 respond to the promotion, the marketer can say with confidence that campaign led directly to 10% direct responses. This metric is known as the ââ¬Ëresponse rate,ââ¬â¢ and it is one of many clearly quantifiable success metrics employed by direct marketers. In contrast, general advertising uses indirect measurements, such as awareness or engagement, since there is no direct response from a consumer. Measurement of results is a fundamental element in successful direct marketing. The Internet has made it easier for marketing managers to measure the results of a campaign. This is often achieved by using a specific website landing page directly relating to the promotional material. A call to action will ask the customer to visit the landing page, and the effectiveness of the campaign can be measured by taking the number of promotional messages distributed (e.g., 1,000) and dividing it by the number of responses (people visiting the unique website page). Another way to measure the results is to compare the projected sales or generated leads for a given term with the actual sales or leads after a direct advertising campaign. While many marketers recognize the financial benefits of increasing targeted awareness, some direct marketing efforts using particular media have been criticized for generating poor quality leads, either due to poor message strategy or because of poorly compiled demographic databases. This poses a problem for marketers and consumers alike, as advertisers do not wish to waste money on communicating with consumers not interested in their products. Some of these concerns have been addressed by direct marketers by the use of individual ââ¬Å"opt-outâ⬠lists, variable printing, and better-targeted list practices. Additionally, in order to avoid unwanted mailings, members of the marketing industry have established preference services that give customers more control over the marketing communications they receive in the mail. The term ââ¬Å"junk mail,â⬠referring to unsolicited commercial ads delivered via post office or directly deposited in consumersââ¬â¢ mail boxes, can be traced back to 1954. The term ââ¬Å"spam,â⬠meaning ââ¬Å"unsolicited commercial e-mail,â⬠can be traced back to March 31, 1993, although in its first few months it merely referred to inadvertently posting a message so many times on UseNet that the repetitions effectively drowned out the normal flow of conversation. To address the concerns of unwanted emails or spam, in 2003, The US Congress enacted the Controlling the Assault of Non-Solicited Pornography and Marketing (CAN-SPAM) Act to curb unwanted email messages. Can-Spam gives recipients the ability to stop unwanted emails, and set out tough penalties for violations. Additionally, ISPs and email service providers have developed increasingly effective Email Filtering programs. These filters can interfere with the delivery of email marketing campaigns, even if the person has subscribed to receive them, as legitimate email marketing can possess the same hallmarks as spam. There are a range of email service providers that provide services for legitimate opt-in emailers to avoid being classified as spam. Consumers have expressed concerns about the privacy and environmental implications of direct marketing. In response to consumer demand and increasing business pressure to increase the effectiveness of reaching the right customer with direct marketing, companies specialize in targeted direct advertising to great effect, reducing advertising budget waste and increasing the effectiveness of delivering a marketing message with better geo-demography information, delivering the advertising message to only the customers interested in the product, service, or event on offer. Additionally, members of the advertising industry have been working to adopt stricter codes regarding online targeted advertising. Any medium that can be used to deliver a communication to a customer can be employed in direct marketing, including: Email Marketing Sending marketing messages through email or Emailmarketing is one of the most widely used direct-marketing methods. One reason for email marketingââ¬â¢s popularity is that it is relatively inexpensive to design, test, and send an email message. It also allows marketers to deliver messages around the clock, and to accurately measure responses. Online Tools With the expansion of digital technology and tools, direct marketing is increasingly taking place through online channels. Most online advertising is delivered to a focused group of customers and has a trackable response. * Display Ads are interactive ads that appear on the Web next to content on Web pages or Web services. Formats include static banners, pop ups, videos, and floating units. Customers can click on the ad to respond directly to the message or to find more detailed information. According to research by eMarketer, expenditures on online display ads rose 24.5% between 2010 and 2011. * Search: 49% of US spending on Internet ads goes to search, in which advertisers pay for prominent placement among listings in search engines whenever a potential customer enters a relevant search term, allowing ads to be delivered to customers based upon their already-indicated search criteria.This paid placement industry generates more than $10 billion dollars for search companies. Marketers also use search engine optimization to drive traffic to their sites. * Social Media Sites, such as Facebook and Twitter, also provide opportunities for direct marketers to communicate directly with customers by creating content to which customers can respond. Mobile Through mobile marketing, marketers engage with prospective customers and donors in an interactive manner through a mobile device or network, such as a cellphone, smartphone, or tablet. Types of mobile marketing messages include: SMS: (short message service) ââ¬â marketing communications are sent in the form of text messages, also known as texting. MMS: (multi-media message service) ââ¬â These messages use elements such as images, video, and audio; Mobile Applications: Smartphone-based mobile apps contain several types of messages. Push Notifications are direct messages sent to a user either automatically or as part of a campaign. They include transactional, marketing, geo-based, and more. Rich Push Notifications are full HTML Push Notifications. Mobile apps also contain Interactive ads that appear inside the mobile application or app; Location-Based Marketing: marketing messages delivered directly to a mobile device based on the userââ¬â¢s location; QR Codes (quick-response barcodes): This is a type of 2D barcode with an encoded link that can be accessed from a smartphone. This technology is increasingly being used for everything from special offers to product information. Mobile Banner Ads: Like standard banner ads for desktop Web pages but smaller to fit on mobile screens and run on the mobile content network Direct Mail The term ââ¬Å"direct mailâ⬠is used to refer to communications sent to potential customers or donors via the postal service and other delivery services. Direct mail is sent to customers based on criteria such as age, income, location, profession, buying pattern, etc. Direct mail includes advertising circulars, catalogs, free-trial CDs, pre-approved credit card applications, and other unsolicited merchandising invitations delivered by mail to homes and businesses. Bulk mailings are a particularly popular method of promotion for businesses operating in the financial services, home computer, and travel and tourism industries. In many developed countries, direct mail represents such a significant amount of the total volume of mail that special rate classes have been established. In the United States and United Kingdom, for example, there are bulk mail rates that enable marketers to send mail at rates that are substantially lower than regular first-class rates. In order to qualify for these rates, marketers must format and sort the mail in particular ways ââ¬â which reduces the handling (and therefore costs) required by the postal service. In the US, marketers send over 90 billion pieces of direct mail per year. Advertisers often refine direct mail practices into targeted mailing, in which mail is sent out following database analysis to select recipients considered most likely to respond positively. For example, a person who has demonstrated an interest in golf may receive direct mail for golf-related products or perhaps for goods and services that are appropriate for golfers. This use of database analysis is a type of database marketing. The United States Postal Service calls this form of mail ââ¬Å"advertising mailâ⬠(admail for short). Telemarketing Another common form of direct marketing is telemarketing, in which marketers contact customers by phone. The primary benefit to businesses is increased lead generation, which helps businesses increase sales volume and customer base. The most successful telemarketing service providers focus on generating more ââ¬Å"qualifiedâ⬠leads that have a higher probability of getting converted into actual sales. The National Do Not Call Registry was created in 2003 to offer consumers a choice whether to receive telemarketing calls at home. The FTC created the National Do Not Call Registry after a comprehensive review of the Telemarketing Sales Rule (TSR). The do-not-call provisions of the TSR cover any plan, program, or campaign to sell goods or services through interstate phone calls. The provisions do not cover calls from political organizations, charities, telephone surveyors, or companies with which a customer has an existing business relationship. Canada has its own National Do Not Call List (DNCL). In other countries it is voluntary, such as the New Zealand Name Removal Service. Voicemail Marketing Voicemail marketing emerged out of the market prevalence of personal voice mailboxes, and business voicemail systems. Voicemail marketing presented a cost effective means by which to reach people directly, by voice. Abuse of consumer marketing applications of voicemail marketing resulted in an abundance of ââ¬Å"voice-spam,â⬠and prompted many jurisdictions to pass laws regulating consumer voicemail marketing. More recently, businesses have utilized guided voicemail (an application where pre-recorded voicemails are guided by live callers) to accomplish personalized business-to-business marketing formerly reserved for telemarketing. Because guided voicemail is used to contact only businesses, it is exempt from Do Not Call regulations in place for other forms of voicemail marketing. Voicemail courier is a similar form of voicemail marketing with both business-to-business and business-to-consumer applications. Broadcast Faxing Broadcast faxing, in which faxes are sent to multiple recipients, is now less common than in the past. This is partly due to laws in the United States and elsewhere which regulate its use for consumer marketing. In 2005, President Bush signed into law S. 714, the Junk Fax Prevention Act of 2005 (JFPA), which allows marketers to send commercial faxes to those with whom they have an established business relationship (EBR), but imposes some new requirements. These requirements include providing an opt-out notice on the first page of faxes and establishing a system to accept opt-outs at any time of the day. Fax senders must begin complying with these new requirements, which are described in this fact sheet. Roughly 2% of direct marketers use fax, mostly for business-to-business marketing campaigns.[16] Also, due to the popularity of a variety of digital communication methods, the overall use of faxes is less than in the past. Couponing Couponing is used in print and digital media to elicit a response from the reader. An example is a coupon which the reader receives through the mail and takes to a storeââ¬â¢s check-out counter to receive a discount. Digital Coupons: Manufacturers and retailers make coupons available online for electronic orders that can be downloaded and printed. Digital coupons are available on company websites, social media outlets, texts, and email alerts. There are an increasing number of mobile phone applications offering digital coupons for direct use. Daily Deal Sites offer local and online deals each day, and are becoming increasingly popular. Customers sign up to receive notice of discounts and offers, which are sent daily by email. Purchases are often made using a special coupon code or promotional code. The largest of these sites, Groupon, has over 83 million subscribers. Direct Response TV Direct marketing via television (commonly referred to as DRTV) has two basic forms: long form (usually half-hour or hour-long segments that explain a product in detail and are commonly referred to as infomercials) and short form, which refers to typical 30-second or 60-second commercials that ask viewers for an immediate response (typically to call a phone number on screen or go to a website). TV-response marketing ââ¬â i.e. infomercials ââ¬â can be considered a form of direct marketing, since responses are in the form of calls to telephone numbers given on-air. This allows marketers to reasonably conclude that the calls are due to a particular campaign, and enables them to obtain customersââ¬â¢ phone numbers as targets for telemarketing. One of the most famous DRTV commercials was for Ginsu Knives by Ginsu Products, Inc. of RI. Several aspects of ad, such as its use of adding items to the offer and the guarantee of satisfaction were much copied, and came to be considered part of the formula for success with short-form direct-response TV ads (DRTV) Direct Response Radio In direct response radio, ads contain a call to action with a specific tracking mechanism. Often, this tracking mechanism is a ââ¬Å"call nowâ⬠prompt with a toll-free phone number or a unique Web URL. Results of the ad can be tracked in terms of calls, orders, customers, leads, sales, revenue, and profits that result from the airing of those ads. Insert Media Another form of direct marketing, insert media are marketing materials that are inserted into other communications, such as a catalog, newspaper, magazine, package, or bill. Coop or shared mail, where marketing offers from several companies are delivered via a single envelope, is also considered insert media. Out-of-Home Out of home direct marketing refers to a wide array of media designed to reach the consumer outside the home, including transit, bus shelters, bus benches, aerials, airports, in-flight, in-store, movies, college campus/high schools, hotels, shopping malls, sport facilities, stadiums, taxis ââ¬â that contain a call-to-action for the customer to respond. Direct Response Magazines and Newspapers Magazine and newspaper ads often include a direct response call-to-action, such as a toll-free number, a coupon redeemable at a brick-and-mortar store, or a QR code that can be scanned by a mobile device ââ¬â these methods are all forms of direct marketing, because they elicit a direct and measurable action from the customer. Direct Selling Direct selling is the sale of products by face-to-face contact with the customer, either by having salespeople approach potential customers in person, or through indirect means such as Tupperware parties. Grassroots/Community Marketing The door-to-door distribution of flyers and leaflets within a local community is a business-to-consumer form of direct marketing used extensively by restaurants, fast food companies, and many other business focusing on a local catchment. Similar to direct mail marketing, this method is targeted purely by area and community, and costs a fraction of the amount of a mailshot, since it is not necessary to purchase stamps, envelopes, or address lists with the names of home occupants.

Report on Small Pox Assignment Example | Topics and Well Written Essays - 500 words
Report on Small Pox - Assignment Example Smallpox can be transmitted as a biological (terrorist) weapon and through contaminated items also since the virus can remain on cloths, surfaces and bedding for over 7 days (Baker & Nicklin, 2011). According to Baker and Nick (2011), the viral infection begins in the lungs from which it moves to the bloodstream, and the finally to the brain, kidneys, intestines, skin, and other body parts. The activity of the virus in the cells of the skin results in rashes that then form flat, red lesions called macules which also metamorphose into raised blisters (vesicles). Approximately 2-3 weeks after infection, pimples which are filled with pus (pustules) begin to appear. There are four varieties of the variola virus. Classic variola (smallpox) is the most communicable and infects over 30% of those who encounter it. Hemorrhagic variola kills faster and at a higher rate than its classic counterpart, with infected persons (commonly pregnant women) dying even before the formation of pustules. Malignant/ flat variola has a death rate closing in on the 100%, evolves slower than classic forms and is characterized by flat lesions. Modified variola, on the other hand, affects those who have undergone immunization, occurring as a result of response of the immune system. Generally, variola major (smallpox) has 30% death rate while alastrim (variola minor)ââ¬â¢s death rate is 1% since it is milder (Baker & Nicklin, 2011). The pioneer signs of smallpox appear 12-14 days following infection. During the period of incubation (7-17 days following infection), an infected individual appears healthy and cannot infect others. However, after the incubation period, flu-like symptoms such as fever, headache, extreme back pain, severe fatigue, vomiting, diarrhea, and general discomfort are characteristic indicators of smallpox. After a few days, red flat spots surface on the individualââ¬â¢s forearms, hands, face and on the trunk. In 24 or 48 hours, these lesions become small clear fluid

Race Relations Act 1976 And The Actions That Athea And The Commission Essay
Race Relations Act 1976 And The Actions That Athea And The Commission For Racial Equality Could Take In Respect Of Them - Essay Example In the U.K. the Government has recognized the importance of preserving equality and civil liberties in the interest of overall progress in the State. The Race Relations Act framed in 1976 specifically deals with discrimination on the grounds of race in the fields of employment, training education, housing and other services deemed necessary to ensure that the civil liberties of an individual are not hampered*3. This act was further amended in 2000 to incorporate discrimination from all public bodies. Chapter 74, Section 1 of the Race relations Act sets out the grounds that will constitute a violation of the provisions of the Act by any person when ââ¬Å"on racial grounds, he treats that other less favorably than he treats or would treat other personsâ⬠especially when ââ¬Å"he cannot show [it] to be justifiable, irrespective of the color, race, nationality or ethnic or national origins of the person to whom it is applied.â⬠Part II of the Act deals specifically with discr imination exercised by employers and under Section 4, an employerââ¬â¢s action would also be deemed to be unlawful under the provisions of this act if he discriminates against an employee or potential employee by ââ¬Å"refusing or deliberately omitting to offer him that employment.ââ¬

Csr and mcdonalds Essay Example | Topics and Well Written Essays - 1750 words
Csr and mcdonalds - Essay Example As a corollary of the above job enrichment and enlargement policies and programs were initiated with a view to encouraging and motivating the staff to accept new challenges. For instance employee welfare practices though were not many, could be seen to a certain extent in some of the surveyed restaurants. Absenteeism and labor turnover figures were low. In fact labor turnover figures were high only among crew members because most of them were college undergraduates doing a stint to cover up tuition fees. Most probably customer harassment could have contributed to the above average labor turnover figures among the crew members at McDonalds restaurants in Leicester in particular and elsewhere in general. McDonald's pay is based on performance and the monetary incentives are intended to encourage employees to perform better in the jobs and employees might require non-monetary incentives too to remain their current jobs in the long run whilst reducing the degree of turnover. Thus the pay rates determination criteria at McDonald's are essentially determined by evaluation techniques of the HRM Department. For example employees at these restaurants were given a selected array of monetary and non-monetary incentives with the hope that the well trained and skilled employees would not leave their jobs at least in the short run. While HRM related aspects of the retention strategy was focused on employee welfare, there was much less focus on the long term organizational capability building measures to retain employees. The best example of this inadequacy can be found in the fact that the whole staff at McDonald's takes customer harassments for granted.This research study has found a significa nt amount of positive correlation between McDonald's HRM strategy and productivity gains though the extent to which such gains can be attributed to HRM strategy isn't clear. In the first instance as suggested in the Literature Review, the theoretical perspectives on motivation and performance have taken a new turn with greater emphasis on Strategic HRM. Secondly cultural diversity of the workforce at McDonald's requires such SHRM practices to be aligned with international trends. Thus as borne out by the majority of responses to the questionnaire performance related pay at McDonald's would have a positive impact on employee motivation and the Company would try to maximize their incentives. However it has been identified as the most desirable policy to achieve organizational goals and survive in the long run. McDonald's success in Leicester could be attributed to well managed labor relations and good motivation policies in order to encourages greater participation of the employees in the decision making process of the company. Next those four McDonalds restaurants in Leicester along with the other three have not displayed any noteworthy divergence from the theoretical and conceptual contingency framework of analysis applied here as illustrated in the McDonald's approach to CSR. For example all McDonald's restaurants place equal emphasis on animal welfare, education, environment, people, quality and safety and Ronald McDonald's House Charities (RMHC).

Digital Marketing in the Healthcare Industry Research Paper
Digital Marketing in the Healthcare Industry - Research Paper Example Through the system, the number of patients served per day increases and the space required to store all the data concerning the patients becomes minimal. Thus, there is increased workflow and improved productivity in the health sector. The system replaces paper records that are usually incomplete; some parts usually found in different places thus being fragmented and hard to find and read (Cavalieri and Rupp 22). The accuracy and efficiency of the health sector also improve the systems results in improved results management and the care of the patients with reduced margins of error within the medical care practice. There is also a reduction in the production cost such as overtime expenses for labor and the costs of transcription. For this reason, this automatically results in an increase in the acceptance of the system in the health sector. EMR also leads to the development of customizable and scalable records that are in a position to grow with time. The advancement of e- prescribing and documentation of the clinical records leads to improved practice in the health care system. There also results from an enhancement in the ability to more efficiently and accurately process the patients bills. The ultimate goal of having an EMR within a given hospital, is to make patients data available to anyone who needs it, where and when they need it. With the system in place, patients lab results can be obtained with much ease compared with the paper system, and this will lead to saving a lot of time and money. The system provides data that is always ready for analysis, audit, quality assurance and research and disease surveillance for continuing medical education (Cavalieri and Rupp 36). In conclusion, the emergence of the EMR into medical systems is expected to decrease medical errors, reduce health care costs and influence peoples decision in selecting their

QI Plan Part II--Quality Data Collection Research Paper
QI Plan Part II--Quality Data Collection - Research Paper Example A large number of software packages are available in the market for recording daily hospital records. A tool as simple as excel spreadsheet can also be used to handle small amount of transactions for smaller organizations. Databases such as access can also be utilized. This would maintain a daily list of electronic records making it easy to sort, filter and backtrack any information. Health Management information systems (HMIS) can also be used to record and monitor data. This could contain supervisory data, clinic record data, drug stock-outs data, functioning of outreach services and health workers availability. The information could include internal activities, number of beds, daily admissions and discharges, number of causalities and duration of stay. Self administered surveys help in revealing characteristics of the entire population by considering large sample sizes. Many questions can be asked on a given topic and the response to them can be analyzed with flexibility. These surveys eliminate the limitations of self-administered surveys. Personal interviews are an alternative to surveys. The control of the interview is in the hands of the interviewer rather than respondent leading to better response and accuracy. The scope for confusion decreases significantly. Also the interviews are useful in cases where the interviewee is a senior executive or a leader of an organization and doesnââ¬â¢t have time to fill written survey (Data Collection Tools). Focus groups are used to obtain specific information which may not be possible using other methods. The focus group consists of people who exhibit a certain peculiar characteristic. For example, the satisfaction level of heart patient who went through bypass surgery in a hospital can be noted a few months after the surgery by forming their focus group. Focus groups contain 6-12 people generally. This ensures sufficient diversity in the group without compromising on attention to everyone in the group.

Domestic Violence Essay Example | Topics and Well Written Essays - 500 words - 2
Domestic Violence - Essay Example The new policy insists that children be taken from their households even with only two incidences of problematic behavior then the parents will have to undergo treatment, therapy or counseling before the children can be given back to their care. This method actually severs family ties and changes developmental needs of children significantly. Maintaining the family as complete and intact ensures that the children will have the connection and bond with their families, even it may be dysfunctional. It is, then, important to guarantee their safety while protecting the family as a unit. The new policy may protect the children from harm, but it does not protect them from the disadvantages of being disconnected from their families. The new policy should, then, recognize the needs of empowering the parents with problem behaviors to continue correcting their behavior while their children are with them to be able to provide them their developmental needs, as well as, a positive environment.Th e Department of Job and Family Services may have the best in their minds when they created this policy. However, they forgot to take account the importance of family connections and the primary developmental needs of children when they imposed that children should be taken away from their families if there is a case of problematic behavior in the family. Taking children away from their parents should be the last resort unless they are the direct victims of their parentââ¬â¢s abusive behavior.

A Copââ¬â¢s Life Essay Example for Free
A Copââ¬â¢s Life Essay In ââ¬Å"A Copââ¬â¢s Lifeâ⬠Heather MacDonald describes the mediaââ¬â¢s blinding prejudices when it comes to policing and race and supported it with two different copââ¬â¢s life stories. First is about a black man who was shot dead by a cop who was trying to restrain him because he was running naked through traffic pounding cars and received only two mentions in the press outside Seattle. MacDonald compared this story to an angry-cop case that has been videotaped slugging a cuffed black teen once in the head who received 370 stories in the event and flooded the nationââ¬â¢s airwaves and presses. The author describes how being accused of racism affects a cop to do his job. In todayââ¬â¢s world, due to a continuous competition in news and media industry, it seems like most of the news that is coming out today are reconstructed to a way that it will attract more people. And due to the fact that for some reasons, bad news are more catchy than good news and that influential people like policemen are more interesting to talk about, a lot of people are being mislead by mediaââ¬â¢s bias information. I would take the example used by the author in this article as my example. It is an incident of a police officer who has been forced to use his power to stop a civilian who is doing an unlawful violent behavior. The whole story was not out in the news which includes the behavior of the civilian before and just after the latter was cuffed. The only video that they represented was when the civilian was thrown on the hood, but the earlier part that should supposedly concludes the reason why the police officer has to do it was never presented. It was this type of bias reporting that left the police officer guilty and no way to defend himself. Being a cop is not easy for it requires commitment, responsibilities and dedication. Civilians look at you as a perfect person who are not allowed to commit a single mistake and that all of the things that you will be doing should be at the right thing, that is why when a cop is linked to an incident wherein the copââ¬â¢s image is being affected that would make a history and will be talked in news in different forms. Cops will be assaulted, cursed at, assaulted and even shot at but they can never strike back. Bias opinions by the media should stop and the heroic deeds of the cops should be recognized. Part 2 1.

Spectrum Sensing and Spectrum Sensing Techniques
Spectrum Sensing and Spectrum Sensing Techniques Chapter 1.Introduction In recent years there has been an enormous growth in wireless communication devices and wireless users. The ever increasing demand for higher speed and reliability made researchers think about intelligent radios like Cognitive Radios (CR). But major amount of spectrum is available for licensed users. There are various communication bodies like the International Telecommunication Union (ITU), European Conference of Postal and Telecommunications Administrations (CEPT) also European Telecommunications Standards Institute (ETSI) who works on standards of communication that defines the use of spectrum for licensed and unlicensed users. 1.1 Background Spectrum is a valuable resource in communication. Over the past few years as the use of various wireless technology is increasing rapidly so we either need more spectrum or make efficient use of current spectrum to satisfy their needs. One way of making efficient use of spectrum is employing spectrum sharing technique. There are many spectrum sharing techniques available like energy detection, cyclostationary feature detector, and matched filter. Of the above technique matched filter and cyclostationary gives more accurate result but they are bit complex and computationally harder as compared to energy detection technique. Energy detection is the simplest of above three and computationally less complex. 1.2 Motivation Survey has shown that at any given time only portion of spectrum is utilized. According to a report published by FCC (Federal Communications Commission America) in 2003 has set a set of rule for efficient use of spectrum for licensed and unlicensed users. Also OFCOM (Office of Communications United Kingdom) has noticed the underutilization of spectrum. At any given time only portion of spectrum is utilized. Even if the system says there are no frequencies available, there is still some frequency available. These available frequencies are known as spectrum holes or white spaces. Some of the bands are completely occupied by users while some bands go unutilized. And that is inefficient use of spectrum. We must have noticed that in cases of emergencies like the train bomb blast in July 2006 in Mumbai, India cellular network actually failed to support huge amount of customer at the same time, this was also the case during 9/11 in USA. If we were having cognitive radios at that time peop les would have been able to talk to their families and inform about their safety. As we are moving from 3G (Third generation) to 4G (Fourth Generation) we need to make certain changes in our wireless technologies. Below shown is the measurement of 0 GHz to 6 GHz at Berkley Wireless Research Center (BWRC). 1.3 Aim and Objective This thesis emphasises on understanding Cognitive radios, the importance of spectrum sensing for todays world, the issues regarding the same. A simplified Matlab code is used to support our thesis. As the thesis follows you will find more about cognitive radios and spectrum sensing with a technique to generate white space at a specific frequency. The main objective of the thesis is to do survey on spectrum sensing and spectrum sensing techniques. Then do plan a model for the same. A model can be supported by a Matlab code. And after all this we need to analyse the model we suggested and further improvements that can be done in that. 1.4 Thesis Organisation Our thesis is organised as follows: Chapter.2 Literature Review This chapter begins with a brief history about cognitive radios .Which is followed by a detail explanation of Cognitive radios and spectrum sensing and some of the spectrum sensing techniques used. At the end of this chapter a business model for spectrum sensing and multi resolution of CR is given. Chapter.3 System Description This chapter basically deals with sampling and its importance to us. Also you will find technique to get your spectrum at specific center frequency under ââ¬Å"generation of White Spacesâ⬠. Chapter.4 Simulation/Design Analysis As the name suggests, this chapter deals with simulation model and detail explanation of the code used for spectrum sensing using energy detection. In this chapter we have shown the output of the simulation used. Chapter.6 Future Work This chapter suggests some of the future work to be done with this thesis which could be useful for further research in this field. Chapter.7 Conclusion This gives the concluding part of the thesis. Chapter 2 Literature Review In this chapter we are going to discuss about the cognitive radios, like what are they and why are they so important to us. The chapter begins with a short history of cognitive radios, which is followed by a general discussion on OFDM, some of the challenges faced by cognitive radios in real environment, and also some of the applications of cognitive radios. We have tried to explain spectrum sensing in brief and the techniques used for spectrum sensing in todays world. Finally a business model for spectrum sensing is showed which is preceded by multi-resolution of Cognitive radios. 2.1 History of cognitive radios Dr. Joseph Mitola III was the first to introduce or propose the theory of Cognitive radios in 1999. According to Dr. Joseph Mitola Cognitive radios will be the radios that are smart and intelligent enough to find the available bandwidth in a spectrum. It will also have knowledge of right information that has to be passed to the user. And user does not have to take some extra effort for that. It is supposed to do this automatically. He has also mentioned in his PhD dissertation that CR is natural extensions of software defined radios. In 2002 the FCC published a report prepared by Spectrum Policy Task Force [SPTF] which says that majority of spectrum is underutilized. And there is actually is not shortage of spectrum but rather we need to make efficient use of the current spectrum. Also in same year 2002 Professor Cave from UK presented a report which speaks of the possibility of selling bandwidth to the user depending on their requirement. But it would not be fair to give unlicensed user allow to use licensed spectrum. So in December 2002 FCC issued a Notice of Enquiry (NOI) to see TV channel bands can be made available to unlicensed users. Then in 2003 FCC forms a set of rules and proposed interference temperature model for keep track of interference. Later in the same year Notice of Proposed Rulemaking (NPRM) tried to see into issues related to cognitive radio technology where it also pointed out Cognitive radios is a advanced technology which could help efficient use of spectrum by licensed users in own network and by sharing spectrum and with unlicensed users by negotiating when required. This encouraged many researchers in the field of cognitive radios. Major progress in cognitive radios took place in the year 2004, where FCC published NRPM which showed possibility of allowing secondary users to use licensed spectrum. FCC opened three bands for unlicensed users which are 6525 to 6700 MHz, 12.75 to 13.15 GHz and 13.2125-13.25 GHz. This allowed cognitive dev ices to transmit six times more. Also IEEE standards are working parallel to the FCCs. Spectrum pooling system by Professor Timo A Weiss from Karlsruhe University Germany), OFDM based Cognitive radios by professor Ian F Akyildiz et al from GIT (USA) are some of the promising works in Cognitive radios. there are many researches are done, many still going on in Europe, Asia, and America, exploring various aspects of cognitive radios. In Jan 2010 first call over a CR network was made in university of Oulu using CRAMNET (Cognitive Radio Assisted Mobile Ad Hoc Network). 2.2 Cognitive radio With the development of wireless communication devices and technologies in WLAN and WAN spectrum is becoming scarcer. Low frequency bands which are near few GHz are very scarce and highly congested. In current wireless system we are using fixed spectrum allocation scheme. In fixed spectrum allocation scheme a part of spectrum is owned by an operator. Unlicensed users are not allowed to use that spectrum. This leads to the problem of spectrum scarcity. Survey has shown that more than 50% of the spectrum is underutilized. This is where Cognitive Radio (CR) is comes into picture. CR is introduced to solve the problem of spectrum sharing. Cognitive Radios actually scans the spectrum and during scanning it looks for spectrum holes. The main objective of the cognitive radios is to look for opportunities or white spaces in spectrum band as quickly and as much as possible. And when we say opportunity, opportunity could be in time or frequency domain. Also when we locate this spectrum holes opportunistically we also need to vacant the occupied spectrum as soon as primary user comes back. Here primary user means the users whose spectrum we are using (licensed user) and secondary means the unlicensed users. Cognitive radio is a pattern for wireless communication technology in which either a network or a wireless node changes its transmission or reception parameters to communicate efficiently avoiding interference with licensed or unlicensed users. These altered parameters are associated with the active monitoring of several factors in the external and internal radio environment e.g. radio frequency spectrum, user behaviour. Cognitive radio can be said as next generation of software defined radio (SDR). They are flexible in terms of their transmission characteristics in terms of frequency, bandwidth, ISP which makes smart decisions to configure the SDR at any point in time to achieve a particular goal. By combining these two technologies makes a radio intelligent and flexible and which helps to adapt it to the variations in the environment, user requirements as per the other radio users. Adaptation to changes and requirements should lead to highly reliable communication whenever and wherever required, while making efficient use of spectrum. Good cognitive radio uses analysis done for long period to know about the environment and also his own behaviour. There are various parameters taken into account to decide transmission and reception changes, we can distinguish certain types of cognitive radio. The main two are as follow: Full Cognitive Radio : It is also known as Mitola radio in which every possible parameter which can be observed by a wireless node is taken into consideration to take decision Spectrum Sensing Cognitive Radio: It is the type in which only the radio frequency spectrum is considered. And Depending on the parts of the spectrum available for cognitive radio, we can distinguish as: Licensed Band Cognitive Radio: It is the type in which cognitive radio is capable of using bands assigned to licensed users, apart from unlicensed bands, such as U-NII band or ISM band. Unlicensed Band Cognitive Radio: This can only utilize unlicensed parts of radio frequency spectrum only or the bands which are free to use. 2.3 About OFDM OFDM stands for Orthogonal Frequency Division Multiplexing. It is generally a type of Frequency Division Multiplexing (FDM) rather a special case in FDM. What makes it special is its orthogonal behaviour. Now the word orthogonal basically means mutually independence. When we say A is orthogonal to B, we mean that A has no vector in direction of B and vice versa or in other words A and B is mutually independent. Or the integral of two signals over one period is 0. In OFDM a single signal is first multiplexed and modulated independently to create orthogonal signals. This means the signal is first divided into number of smaller streams and then modulated further before transmission. For example imagine a slicing of cheese and grilling or cheese. Slicing is like FDM where whole data is sent in a bunch and grilling is like OFDM where the data to be sent is first divided into smaller data and then processed to transmit further like OFDM. Figure shown below is one more way to understand the concept of OFDM. On the left hand side is a big container which carry whole bunch of data at one time and take it to the destination. And on right hand side is four smaller containers where each carry smaller portion of data and take it to the destination. These smaller containers can be assumed as sub-carriers. And in case of OFDM they are orthogonal sub-carriers. The main advantage over here is that even if some of the cheese is lost during grilling, still we have not lost all the cheese. In OFDM input data with high data rate is first passed thorough serial to parallel converter. This parallel divided data is then modulated on individually. And parallel to serial conversion is done before transmission. This parallel divided data is our sub-carriers. These sub-carriers must be orthogonal. 2.4 Cognition cycle Above figure shows the rough model of Cognition Cycle. It reads the surrounding environment and makes decision accordingly. When we say decision we mean cognitive radio sense the requirement or urgency that may be in terms of changing a channel or churning from one technology to another depending upon the scenario. There are different stages where it observes the environment, learns it and then plans its action make required decision and then execute its plans. It is much like a radio with a power of thinking which was not been able before. The figure below shows the cognitive radio architecture suggested by Dr. Mitola. 2.4.1 Some important terms 2.4.1.1Wireless Environment/Outside world- It refers to a communication environment that includes any communication devices and the frequency bands they are working in. 2.4.1.2 Spectrum sensing- It is the technique used by cognitive radios to sense the spectrum. This action involves finding availability of white spaces or spectrum holes in the spectrum. 2.4.1.3 Spectrum Management- It involves catching the best spectrum available so as to satisfy user communication requirements. Cognitive radios should decide on the best spectrum band so that it can meet the Quality of service required for all available frequency bands, therefore these functions are necessary for Cognitive radios. These management functions can be classified as: Spectrum analysis Spectrum decision Spectrum Mobility: It is defined as the process when a cognitive radio device exchanges its frequency of operation. Cognitive radio networks target to use the spectrum in a dynamic manner by allowing the radio terminals to operate in the best available frequency band, maintaining seamless communication requirements during the transition to better spectrum. Spectrum Sharing: providing the fair spectrum scheduling method. One of the major challenges in open spectrum usage is the spectrum sharing. It can be regarded to be similar to generic media access control MAC problems in existing systems 2.5Cognitive Radio Challenges Three main problems experienced by CR are as follows: Interference (Mainly because of Hidden Nodes). Security. Control. They are described as follows: 2.5.1 Interference and the Hidden Node Problem Ideally while designing a CR we should consider that it does not have any impact on existing radio users, but in practically some impact is expected. If a particular user have non-cognitive radios, it is essential to study and make a note that how they would be affected by the interference of CR, mainly with respect to sharing resources such as spectrum, time, space etc. CR adaptive nature could be difficult to predict and thus making it hard to control the behaviour of a CR which will concern for user who faces CR interference issue. In communication industry the main concern about CR is the hidden node problem. This scenario arises when a CR is not capable to detect an interference with any of non-cognitive radios within its range, not only because of CRs own spectrum sensing is ineffective but also due to some non-cognitive radios are hidden. For example, if a transmitting contemporary user is not in the range from the CR, its transmission power may not be strong enough at the CRs location, it may be reduce than the noise floor which makes it more difficult to get detected. As the CR might not be able to detect a transmission by a contemporary user and similarly unaware of availability of the receiving by a contemporary user. Consequently, if it is confirmed as safe to use the contemporary users frequency and CR starts transmitting, at the contemporary receiving end it will create interference. The CR may have a limited view of spectrum provided from wide spectrum measurements which may cause interference with the receiving user. The localised spectrum view denotes that a CR should be potential to find transmitting user those are communicating below the noise level, since the strength of the received signal is very weak at the CRs location. Similarly a situation can occur where the signal attenuate by distance, thus user transmission is blocked by obstacles such as buildings, towers, hills or mountains. For example consider a CR in a valley would have a limi ted picture of the surrounding radio environment, as compared to that if it were located on top of a hill. 2.5.2 Security Concerns CR may be vulnerable to malicious effect, resulting into unexpected or problematic behaviour of individual CRs or complete networks. This problem springs up from the potential to re-program CRs in an unauthorized way. Hacking or placing a vulnerable code, virus on a network might enable criminals to steal valuable information from a CR through electronically, fool a network operator into charging others for services or achieve potentially widespread denial-of-service. A considerable amount of regulatory work will require to be done to clarify who would be responsible for the various security areas of CR, software developers, manufacturers, network operators and CR users themselves may all have a role to play. The CR security issue is closely related to that of SDR, which already discussed and hence not repeated here. Instead, a brief summary of the issues is given. Downloading software updates over an air interface poses some specific problems for security. Several digital signatures will be required for each piece of downloaded software in order to meet likely regulatory requirements. Exactly who is necessary to authorize software downloads must be standardized before any large scale deployment of over-the-air updates can be realized. 2.5.3 Burden of Control and Regulatory challenges A CR in reality will have some effect on different spectrum users the compliance of these new radios is likely to focus on a Policy module defined within a CR, which will determine the boundaries of CR behaviour. It is important while studying CR; to consider how users would not be affected by interference from CR devices and the exact operation and nature of a proposed CR policy system must be understood carefully. It is likely to include a detail case study of the specifications and characteristics of all the contemporary users for a specific CR or complete network of CRs may share the resources. The effort in controlling CR devices, it is necessary to ensure their behaviour is properly or not, even in the case of faulty or tampered devices, that measures are quickly implemented to intense problems. This will involve policies and standards which are created in a universal digitally interpretable policy, so that all CRs can understand the same. Monitoring techniques and powerful alg orithms are required to enable detection and identification of bad CRs and in this way it provides traceability to find or determine who is responsible for the issue. In addition to these challenges, spectrum regulators and spectrum managers will require providing access to licensed spectrum in such a way that is traceable, transparent and highly dynamic. If CRs are allowed to cover international territory additional effort will be required, due to the necessity to provide and collaborate cooperation with other countries. Assuming that acceptable control of CR policy behaviour is technically possible and feasible, it may turn out to be such a great burden that it will be simply not economically viable and the benefits of CR are outweighed by this burden. 2.6 Important Applications for Cognitive Radio are Downloading of audio and video files on mobile handsets. This application requires moderate data rates and near-ubiquitous coverage. Emergency services communications: It requires interoperability and a moderate data rate with local coverage. Broadband wireless networking: Very high data rate required but CR users have option to accept limited coverage, e.g. hot spots. Multimedia wireless and sensor networking: Broad range of data rates may be required. 2.7 Spectrum Sensing Spectrum sensing is the process performing measurements on the part of spectrum and on the basis of measured data making a decision related spectrum usage. As the requirement and quantity of users is getting increased day by day, it is necessary for ISPs to have large amount of spectrum in order to achieve the QOS (Quality of Service). This leads the interest in unlicensed spectrum access and spectrum sensing is vital concept of this. In a situation where there are licensed user and any unlicensed exists, licensed user (primary user) is to be protected and no unlicensed user can interfere any licensed users operation and such cases Spectrum sensing is also useful to detect the existence or non existence of a primary user. Spectrum sensing is an important concept for exploring spectrum opportunities for the secondary spectrum usage in real-time. It detects the unused spectrum and shares it without any noticeable interference with other users. It is an important requirement of the Cogn itive Radio in order to sense spectrum holes. Detecting primary users is the most efficient way to detect spectrum holes. 2.8 Spectrum Sensing Techniques Available Spectrum sensing plays a vital role in cognitive radios. And the type of spectrum sensing techniques to choose more or less depends upon the spectrum sensing technique. A method such as energy detection proves to be one of the simplest of all, but it doesnt works well at low SNR, varying noise levels, fading. On the other hand technique such as Matched filters shows better performance, but they comes complex receiver design. We are going to discuss some of these techniques as we proceed further. 2.8.1 Matched Filter Technique This is the technique which takes minimum amount of sensing time. In this method of spectrum detection, receiver receives a pilot signal along with the data that is sent by the transmitter. A pilot signal is a single frequency that is used for synchronisation. All the secondarys those are struggling for spectrum should have knowledge of this pilot signal. There should` be tight timing synchronisation between primary and secondary. They are also required to know about the kind of modulation being used, pulse shaping. Also secondarys must have another receiver for every primary. This kind of techniques also fails when there is frequency offset. Examples of this technique are TV signals, CDMA with pilot, also used in OFDM. 2.8.2 Energy Detection technique This is the most simples of all techniques. In this the receiver has no knowledge of the transmitted signal. The receivers need not to have knowledge about the modulation type or any kind of pilot signal. Earlier energy detection was done with the help of a LPF (Low Pass Filter), Digital to Analog converter (D/A), and square law device that used to calculate the energy of the signal. Later it is done by making use of fast Fourier transform (FFT). This is known as periodogram method in energy detection. 2.8.2 Cyclostationary Feature Detection Signals are modulated with sine waves or cyclic prefix as in OFDM. And they are periodic. This periodic property of a signal helps it to be cyclostationary. This technique basically uses this principle of spectral correlation to detect the spectrum. Even if signals have similar PSD (Power Spectral Density) but they have do not have similar spectral correlation. 2.9 Multi-resolution for Cognitive Radio Sensing The concept of multi-resolution for Cognitive Radio can be applied with different methods but, the basic idea is the same. The whole spectrum is first sensed by using a coarse resolution. After this first step fine resolution sensing is done on a part of interested bands. In this way CR avoids itself from sensing the spectrum at one time and thus saving time and power. In this way, the sensing time is reduced and the power also been saved from unrequited computations. Also the multiple antenna architecture helps parallel processing and enables to reduce the sensing time. But, it increases the chip area and consumption of power which is not desirable. Also for coarse resolution sensing the mixer has to produce many frequencies and Also it should switch to one frequency for beginning the fine resolution sensing. If the signal is low pass signal then we can use fine resolution to scan the whole spectrum. Because low pass signal has low center frequencies and its sampling is doable. But for pass band signals it is not feasible to scan the whole spectrum. Because, for example say if we have some signal with center frequency of 850 MHz, it is not practically possible to do sample that signal. As according to Nyquist theorem sampling rate should be at least twice that of center frequency. Therefore it is practically not possible to sample a signal at 1600 Mega Hertz. 2.10 Business Model for Spectrum Sensing So far we have discussed about Cognitive radios and spectrum sensing in details. Since this is telecom, and telecom involves huge capital investment. One of the most costly things in telecom is getting the license itself and then comes the infrastructure and installations etc. Currently most of countries work on static spectrum allocation basis. For spectrum sensing to work we need some kind of regulation or set of rules that all will be ready to work with. A team from Brussels University has suggested a model for the same. The same model is discussed in brief below. This model is divided into four main categories. i. Ownership- Ownership simply means the ownership of license. One who has license is authorized to use particular band of spectrum. And if another licensee wants to share a spectrum then it will depends on parameters discussed below. If the operator is unlicensed then there is now issue of ownership. ii. Exclusivity- Exclusivity means whether or not a particular operator is exclusively assigned a band of spectrum. That will be issue of regulator to decide to exclusively assign a spectrum to a specific user. If it is assigned exclusively then nobody can access that band of frequency, and if not then those bands of frequencies will be available for sharing. iii. Tradability- Tradability means whether or not a terminal is allowed to switch between frequencies from different operators. If tradability is permitted frequency band or bands can be auctioned for sale or given on lease. iv. Neutrality- It is possible that some of frequency bands can be accessed by number of RATs (radio Access Technology) or may be limited to a particular RAT. If frequency bands are not available to number of RATs then that band need to address more issues, such as setting technical conditions to access the band and coordinating the cooperation between multiple technologies. Unlicensed: Unlicensed deals with the band of frequencies which are free to use, like ISM band. Common example for this is Wi-Fi which operates in 2.4GHz. This band of frequency is available to all and there is special condition to access this band. Single RAT Pool: This pool is related to a group of licensees which are not exclusively assigned any band of frequency and using same RAT. Multi RAT Pool: It is similar to Single RAT Pool except that it has multiple RATs. Single RAT Market: In this each operator is assigned with a separate frequency, but that can be accessed by the conditionally secondarys. Multi RAT Market: In this the operator is a licensee and is exclusively assigned with a band of frequency, and also with tradability. Flexible Operator and Static Spectrum: If a particular band of spectrum is exclusively assigned to an operator and without tradability. And if there is only one RAT, then it is known as Static Spectrum else Flexible Operator. 2.11 Survey outcome As per the literature review we concludes to use Energy detection technique for spectrum sensing as it is the fastest spectrum detection technique available and also it is simpler as compared to other techniques. There are many researches done in this field and many are still doing. Because of the survey we get knowledge about various techniques available in market. This led us to do a simulation model with one of the spectrum sensing technique. Now as far as selection of spectrum sensing technique is concerned, we selected Energy detection technique. The same could be seen in next part of the thesis which includes its design and implementation in simulation model. Chapter 3 Simulation Design 3.1 Sampling and Its Importance Sampling is a process of converting the continuous analog signal to a discreet analog signal and the samples signal is the discreet time representation of the original signal. If the message is coming from a digital source, then it is in the form to be processed by digital communication systems. But in real life not every signal is digital, message signal can be analog. In situation like these, we have to first convert the analog signal into discreet time signal, this is sampling. For this process to work well, sampling rate should be selected carefully or in other words it should satisfy Nyquist criterion. And Nyquist Criterion says that the sampling frequency should be at least twice the maximum frequency in signal. Fs âⰠ¥ 2fmax or T=1/ fmax Where ââ¬Å"Fsâ⬠is sampling frequency, fmax is maximum frequency in the signal. T=Sampling period. Sampling is like reading a signal in analog form and taking its value at that instant of time. So more the samples we take better the resolution of the signal and, signal can be recovered more accurately. But if we take less number of samples, then resolution of the signal decreases. If we go on reducing the sampling rate, then times comes when it is difficult to recover the original signal from the sampled signal or in other words original information in the signal is lost. This is also known as aliasing. Aliasing is the effect which takes place if the signal is sampled less than twice the maximum frequency. 3.2 Types of Signal 3.2.1 Time limited signal- It is a signal which exists for only certain duration of time. Out of this duration, signal does not exist. A rectangular pulse of duration ââ¬Å"Tâ⬠seconds can be considered as time limited signal. x(t)=A â⬠¦ for 0 3.2.2 Band Limited signals- It is a signal which has a frequency spectrum which exists only over a certain range of frequency. The value of signal outside this range of frequency is zero. Mod(X(f))=A â⬠¦.-B 3.3 Sampling Of Low pass and Band Pass signal Low pass sampling theorem states that- a) A band limited signal of finite energy, which has no frequency components higher than W Hertz, is c

Ascites Is A Special Case In The Medical Geriatric Ward Nursing Essay
Ascites Is A Special Case In The Medical Geriatric Ward Nursing Essay Background I think ascites is a special case in this Medical Geriatric ward, because I saw this only one case of ascites in this four weeks practicum. And it is my first time that care patient with ascites. Therefore, I interest and choose this case for studying the nursing care of ascites. In this total patient care study, I will talk about the information and relevant clinical data about this case, the pathophysiology of ascites, the nursing assessment, care plan within patient hospitalize period 20-21/09/2010, plan for future management, and what I learn from this case. Case presentation Patient X is 72-year-old male. He lives in old age home, chair bound for activities of daily living. He is dependent Comprehensive Social Security Assistance, exsmoker and exdrinker. He was admission to Accident Emergency at 20/09/2010. He complained that increased abdominal distension for 2 days, poor appetite, shortness of breath. Physcial condition: conscious, SaO2 95% under room air, afebrile, chest clear, no ankle edema. His primary diagnosis is cirrhosis and gross ascites. He has chronic renal impairment, diabetes mellitus, alcoholic cirrhosis of liver, and chronic ascites. Last time admitted from 05-07/09/2010 for ascites, therapeutic abdominal tap was done and 1.3L ascites fluid was removed. Ascites is an accumulation of extracellular fluid in the peritoneal cavity abnormally. It is the most common major complication of portal hypertension following liver cirrhosis. Blocking the blood flow through the liver sinusoids to hepatic veins and vena cava lead to increased pressure in the portal venous system. It results in plasma leaks out directly from the liver capsule and the congested portal vein into the peritoneal cavity. In addition, hepatocellular damage reduces the livers ability to synthesize normal amounts of albumin, which may deteriorate by leakage of protein in ascites. The evidence of hypoalbuminemia shows in the blood test that the albumin was 24g/L, which is a low level. Adlosterone cannot activate by liver to stimulate the kidneys to retain sodium and water due to hepatocellular damage. Thus, sodium and water are still retention, and the volume of peritoneal cavity fluid grows continue. In this case, the medical management can be performed to patient X should be paracentesis or abdominal tap. This procedure involves using a thin needle to pull ascites fluid from the abdomen (George Longstreth, 2009). Large-volume paracentensis repeated done in combination with Albumin administered intravenously, which can avoid a sudden drop in blood flow in the arteries and to replace each liter of removed ascitic fluid. The physician prescribed IV administration of Albumin 40g after tapping and 30g. 10500ml milk like in color of ascites fluid was removed. If ascites is recurrent, therapeutic abdominal tap may need to be done every two weeks or more frequently, and need to remove up to 10 liters ascites fluid (Cirrhosis Ascites). Ascitic fluid analysis also done before for provides a sample of fluid for analysis, which help for determine the underlying cause of the ascites. No malignant cell was found. An abdominal x-ray and ultrasonography study was done to comfier the presence of ascites. It may locate fluid in the peritoneal cavity. The result did not show dilated bowel. A low sodium and protein diet with restriction of fluids 1L per day. Edema in the form of ascites brings about shallow breathing and impaired gas exchange, as a result of respiratory compromise. We need to Promote and maintain an effective breathing pattern, Arterial blood gas analysis and pulse oximetry monitor every four hours were ordered. Potassium- sparing diuretic Frusemide tablet 40mg twice a day was prescribed. Nursing assessment In abdominal assessment, inspect for skin integrity (pigmentation, lesions, scars, veins, and umbilicus, etc), contour (flat, rounded, etc), distension, respiratory movement, visible peristalsis, and pulsations. Then to auscultation of the abdomen, warmed the stethoscope and the hands, light pressure act on the stethoscope is sufficient to detect bowel sounds and bruits. Then perform percussion of the abdomen; abdominal percussion is aimed at detecting fluid in the ascites, gaseous distension, and masses within the abdomen. Percuss lightly on abdomen according to auscultation site at each abdominal guardant. The sound will be dull if the ascites is presence. Measure the abdominal girth circumference. Assess the amount of distress leaded by the ascites that ask the patient whether the fluid is interfering with sleeping, eating, and breathing (Head-To-Toe Assessment (R. Abdomen), 2008). Nursing diagnosis Excess fluid volume and deficient fluid volume related to fluid shifts secondary to portal hypertension, hypoalbuminemia. It is a combination of volume problem for patient with ascites. The expected outcomes of this care plan are that a normal balance of fluid in the peritoneal cavity will be maintained as evidenced by normal serum albumin levels, without of hypovolemia, decreased abdominal girth, and normal blood pressure measurement. Electrolyte or acid- base are balance. For nursing intervention, monitor the intake and output of patient daily, and record the IO chart. Output should be equal to or exceed intake. Strictly restrict the patients fluid intake. If possible, administer medication with meals, so mealtime fluids can be used for taking medications. Assess the patients dietary intake and habits that may lead to fluid retention. Limit high sodium intake, because it can lead to increased water retention. Administer albumin and diuretics as physician prescribed. Aspirin and nonsteroidal anti-inflammatory drugs may inhibit prostaglandin synthesis and impair sodium excretion by the kidney. Thus, it needs to avoid administering them. Weight the client and measure the patients abdominal girth daily. Closely monitor the patient after paracentesis procedure. To ensure the client has tolerated the procedure well, check the vital signs frequently. Check the dressing carefully to ensure that there are no losing excessive amounts of fluid. Use a pouch to co llect leaking fluid if necessary. Ineffective breathing pattern related to increased intra-abdominal pressure on the diaphragm. The expected outcomes of this care plan are that the patient express relief of feelings of faulty breathing pattern as a result of no shortness of breath and the presence of normal respiratory excursion. Patient has a normal respiratory rate, compared with baseline. (Lynda juall carpenito-moyet) For nursing intervention, position the client in a high-Fowler position with an arm supported with pillows. It can facilitate breathing and relieves the pressure acting on diaphragm. Monitor the clients respiratory status (crackles and increased respirations) for the development of atelectasis or pneumonia to identifies fluid in lungs. Encourage the patient to deep breathe and cough. Use an incentive spirometer to maintain and monitor the respiratory function. If the cough does not loosen to expectorate reparatory secretion, patient can receive ultrasound treatment For improving gas exchange, administer oxygen and blood products as ordered. Teach the patient some breathing techniques, such as pursed-lip breathing to overcome poor breathing patterns (Lynda juall carpenito-moyet). To evaluation the outcome, treatments of ascites enable the client to breath with minimal difficulty. Imbalanced nutrition: less than body requirements related to increased pressure on stomach and intestines, feeling of fullness, poor appetite. The expected outcomes of this care plan are that patient X has appetite and he can keep or increase body weight to an ideal weight and consume sufficient nutrients. Identify deficiencies in daily intake. For nursing intervention, measure the body weight daily to monitors the weight gain or loss. Monitor hemoglobin, hematocrit, albumin, total protein values for monitoring the intake of nutrients, presence of anemia, and colloidal osmotic pressure. Offer and encourage oral hygiene before meals, because poor oral hygiene may cause bad odor and taste, which can reduce appetite. Encourage the patient to rest before meals due to fatigue may decrease appetite and ability to eat. (Lynda juall carpenito-moyet) Provide small, frequent meals for patient instead of few large ones, because even distribution of intake can help to prevent feeling full and ensures enough nutritional intake. Determine food preferences and selected low or no protein and low salt (no more than 1500 mg/day of sodium). If possible, encourage the patients relative to bring permitted foods from home. Prevent constipation to reduce abdominal pressure and fullness. Administer Lactulose liquid 20mal three times a day as physi cian ordered. Plan for management after discharge, patient x should back to the old age home and have follow up by community geriatric assessment service. Recommend short the follow up clinically admission if symptomatic ascites occur. Refer PCU home care nurse for visiting and symptom assessment, and admission clinically for symptom management. Learning points After this total patient care study, I have learnt that more understand the cause and care of ascites. And know that to provide a holistic care not only physical nursing care, but also we need to care the patient mental, social, finical condition, and discharge planning Make sure patient can have a complete care after discharge.

The Presidency of F.D. Roosevelt :: American America History
The Presidency of F.D. Roosevelt In the ancient world, the only way a person could become famous through out the world was to be some sort of king, master warlord, or a descendent of a holy entity. Monarchies, that lasted long enough, kept the memories of their former leaders alive, conquered peoples never forgot the names of their conquerors, and religions have a knack for constantly worshiping the same divine prophets. Some remain of the ancient celebrities are still famous to this day, many of them now shrouded in the mists of time and have become slightly warped by literature and business. For example, the charitable St. Nicholas, warped by language translations and commercialism, is now a large gift giving elf by the name of Santa Claus. But in this day and age, where anyone can record anything he or she wants to, will any of the present day lords and prophets shine as brightly through the shroud of mythology and time as the ones of old? In 500 years - providing anyone is still alive to care - a few men and women will stand out against the haze of time and represent the twentieth century. If there is a group, among them will be at least man involved in World War II. Roosevelt, Churchill, Tojo and Hitler -especially Hitler - are all candidates for the group because of their involvements in the bloodiest wars of the twentieth century. In this world,blood is a hard thing to forget about. Which ones, and in what light they'll be remembered in depends entirely on the biases of historians and the abilities of governments to cover up the embarrassing moments blemishing the memories of their leaders. So if the United States is still around and as powerful as now in five centuries - and hopefully it will - F.D Roosevelt will most likely be one of the mist breakers from the second world war because of the American people's great interest in the presidents involved in wars and the governments talent for hiding less than flattering information from the world. Roosevelt's involvement in the great World War II allows him to fit , comfortably, the U.S standard of fighting presidents. Entering the war on the side of the Allies after a sneak attack by Japan on Pearl Harbor, Roosevelt became a kind of vengeful hero, fighting the good fight in the name of justice. In so doing he ended an economic slump by gearing the

We Must Create More Gardens for the Blind :: Architecture Design Essays
We Must Create More Gardens for the Blind What would it be like to live in a world of blindness? Those who are capable of seeing would probably shudder at the thought of permanently living in this state of dark and seemingly cloistered existence. Yet, one should not fail to realize that, despite their inability to see, the blind do, in fact, dwell in a world filled with a vast array of acute sensations which fully compensate for their lack of visionary capabilities. If anyone is interested in entering, at least temporarily, into the realm of sightlessness, then he should visit the restaurant, Dans le Noir in France. At this unique establishment, one is granted the privilege of enjoying an entire meal served by blind waiters in pitch darkness. The dark environment robs customers of their ability to see and as is so fluently stated on the Dans le Noir website, grants them the opportunity to completely re-evaluate the notion of taste and smelling through our gastronomic and pedagogical process? (http://www.danslenoir.fr). It might seem strange at first to think of eating without being able to see what one is consuming; but this truly might be the best way to dine. After all, the enjoyment of food is mainly centered on one's sense of taste. Yet, when a person is capable of seeing his meal, his attention is undoubtedly averted somewhat from its taste, because instead of focusing on the meal?s flavor, the person?s mind is partially consumed with absorbing the various visionary aspects of both the food as well as the surroundings. By eliminating this distraction, Dans le Noir, most likely, enhances the flavor of their food. If the customer is not capable of seeing what he is about to eat, it is plausible that he might be more willing to try new dishes. How many times has one heard a child proclaim his aversion to a new type of food before he has even tried it? By observing the new and unusual appearance of a dish, children often immediately assume that the meal will as distasteful to their taste buds as it is to their eyes. The truth is, though, that if they could not see the food, they would probably eat it and maybe even enjoy it. The same principle should apply to adults. Thus, it would probably be best for someone to be introduced to roasted octopus, dog, or elephant in a setting similar to that of Dans le Noir.

Mr Nobody Essay
Mr. Nobody is a 2009 science fiction drama film. It was written and directed by Jaco Van Dormael, produced by Philippe Godeau, and starred Jared Leto, Sarah Polley, Diane Kruger, Linh Dan Pham, Rhys Ifans, Natasha Little, Toby Regbo and Juno Temple. The film tells the life story of Nemo Nobody, a 118 year-old man who is the last mortal on Earth after the human race has achieved quasi-immortality. Nemo, memory fading, refers to his three main loves and to his parentââ¬â¢s divorce and subsequent hardships endured at three main moments in his life; him at age nine, fifteen and thirty-four. Nemo tells the story including alternate life paths, often changing course with the flick of a decision at each of those ages. The film uses nonlinear narrative and the many-worlds interpretation to tell the story of Nemoââ¬â¢s life. Mr. Nobody had its world premiere at the 66th Venice International Film Festival where it received the Golden Osella and the Biografilm Lancia Award. Critical response was generally strong and the film was nominated for seven Magritte Awards, winning six, including Best Film and Best Director for Van Dormael. The film was released in Belgium on January 13, 2010. Since its original release, Mr. Nobody has become a cult film, noted for its philosophy and cinematography, personal characters and Pierre Van Dormaelââ¬â¢s soundtrack.[1][2] Plot: In the year 2092, Nemo Nobody is a 118-year-old man, the last mortal on Earth. Humanity has conquered mortality through an endless renewal of cells, and the world now watches in fascination as Mr. Nobody edges towards death. Everyone wants to know the life that he has lived. Nemo himself says that he remembers nothing about his past and a psychiatrist, Dr. Feldheim, tries to make him recall memories through hypnosis; other memories are told to a journalist. Nemo spits out contradictory pieces as he is prodded, and no one is sure what happened and what didnââ¬â¢t. He is less than clear, often thinking that he is only 34 years old. He tells of his life at three primary points in his life: at age nine, when his parents get divorced; at age fifteen, when he fell in love; and at age thirty-four, living his adulthood ââ¬â all three unravelled into many other realities in a nonlinear narrative. At the beginning of the story itââ¬â¢s explained that before birth, children remember everything that will happen in their lives, but at the moment of conception, the Angels of Oblivion make them forget everything. Eventually, the Angels forget about Nemo. Now the boy first has to choose his parents. At age 9, his second choice happens when they divorce, and he has to decide with whom he will live. At a railway station, his mother leaves on a train, while his father stays. In one case he runs to reach the train and his mother manages to pull him in, in another he stays with his father. Epilogue: Before his death, Mr. Nobody tells the journalist that they both donââ¬â¢t exist; they are in the mind of Nemo as a boy, when he is being forced to make an impossible choice. The journalist is then seen looking out of a train window at 9 year-old Nemo as he just misses catching hold of his motherââ¬â¢s hand. The implication is that Nemo made use of that unknown manââ¬â¢s face in one of his imaginary projections into his own distant future. Back at the railway station one final time, Nemo creates a third and totally unexpected choice for himself; he abandons both parents and takes another way out of the dilemma by running away from the tracks in a perpendicular line towards an unknown future. He ends up as the adult Nemo sleeping on a bench by the lighthouse and waiting for Annaââ¬â¢s return. There is, eventually, an ecstatically joyful reunion between them where the two lovingly embrace. At the precise moment Mr. Nobody dies of old age, the expansion of the universe comes to a halt and time reverses itself. The imaginary 118 year-old man then cackles triumphantly as he springs back into awareness with the realization that his younger self has finally found his one true love and life.
