Science and Technology Essays

Science and Technology Essays Science and Technology Essay Science and Technology Essay In recent years, a lack of communication between people has been a significant issue in modern society. It is certainly true of my home town. In this essay, several reasons of the phenomenon and solutions will be discussed. One of the biggest reasons is that people has lost their opportunities to interact with neighbours. There used to be various kinds of local communities few decades ago, however, less and less people participate in these communities because they are busy for work and study in a recent hectic society. The development of technology also has lead to little relationship in the society. While people tend to spend more time at home by internet surfing, the conventional method of communication is losing its importance. A lack of connection within the community units may significantly influence the society. In fact, an increase in the amount of crime in my hometown is now one of the vital issues and many of them seem to be solved by the improvement of local communities. To solve the issues, the local counsel should provide more practical community supports for citizens so that people can gather frequently to exchange their information. It is also important to have special occasions such as local festivals, meetings and educational classes in order to enhance persons quality of life too. In conclusion, even though there are some issues of a lack of communication between people in my hometown, the problems can be solved by enhancement of community supports. In todays world, technology has invaded many aspects of human life. From its gigantic influence on our education and professional development, to the more subtle presence of little gadgets littering our homes, technology is almost everywhere. The reasons for such pervasiveness would boil down to some characteristics that technology by itself possesses. One such characteristic, which is of major interest to many scholars, is the seeming lack of barriers to the spread of technology. It easily penetrates societies and even to remote communities, and once it reaches its destination and catches on, it becomes seemingly difficult to stop its spread. As a result of this, consumer technology like cellular phones, computers, PDAs, radios and televisions have become commonplace in places like Africa, even with all the barriers one would have envisaged. Sadly, it does not need much analysis to realize that even though technology usage is growing rapidly in Africa, we still have numerous developmental problems in our continent. This is a situation where advanced technology is coexisting with underdevelopment in Africa. With all the power that technology wields, it will be a useful exercise to study the ways in which it can be used to solve some of those very problems it has come to meet. In essence, using our little gadgets to solve our big problems. Where would we be as a global community without the study and aid of science and technology? How could humankind have survived through the ages without it? Science and technology have been around for almost as long as time itself. Ancient caveman used early science to learn how to make fire. Caveman, who developed spears from sticks tied with carved stones to hunt with, benefited from the creation of science. The word science (2009,  ¶ 1) comes from the Latin word: scien tia, which means â€Å"knowledge† or â€Å"knowing† and technology (2009,  ¶ 1) comes from the pairing of two greek words: techne and logia which means â€Å"art or craft† and â€Å"skill†. Throughout the centuries, many different fields of science and technology have been developed as ways to better understand the natural world around us. Much of the early studies of science and technology pre dating the sixteenth and seventeenth centuries were dismissed and labeled as being forms of magic or the works of supernatural forces that should remain unchecked and unquestioned. Many early scientific experiments of that time were deemed unethical and frowned upon by society. Advancements in the fields of science and technology are ethical and necessary to the beneficial development of humankind. It would seem that in today’s society the methods of science and technology are once again being scrutinized by society. Many of the break throughs and developmental research that is conducted by scientists in the medical field as well as other fields of science are being deemed by society as unethical. Some extremists are claiming that some of the scientific developments are entering the realm of God’s work, and that we as humans should not be tampering with.

Questionaire Essay Example | Topics and Well Written Essays - 500 words - 1

Questionaire - Essay Example of the world, but then, many articles and reports provide the fact that big countries like USA, do not have a public insurance for majority of their people. In reality there comes uncountable advertisements and news regarding the several insurance companies and policies for health care, but those who need to get benefit does not really get it in majority. This shows that the administration has some drawbacks or to be more precise only a partial action has been taken by the authorities. The talk concerning how to reduce the expenditure for health care among the individual and the group under the health care services provided by public and private authority still continues. There has been a lot of development seen in the field of computers and wireless technology. The system of wireless health care services helps a lot in reducing the expenses to some extent by making arrangements such as fixing the Appointment for the patients, reminding the dates by sending SMS, and these gradually reduces the cost of medical expenses. The provisions of certain Health Care software, and the availability of Health Care consultants, Health Care Service Providers, help a lot in reducing the expenditure for he patients. The health insurance also helps a lot during emergency times. Though the premium rates have to be given in correct time, the effect of the insurance seems to be really worth during more expenses. The health care is usually financed by public and private authority in general. For example the â€Å"Medicare† and the â€Å"Medicaid† set to meet the health care expenses for the aged and the poor respectively. The process of Universal Health Care system which is funded by the tax revenue has two way payment system â€Å"single-payer† and â€Å"multi-payer†. The single payer is government run organization, which acts as the payer and it saves money. The multi-payer system runs with the joint venture of the public as well as private sectors as payer. introduced by the

Argumentative Research Paper on Gun Control Essay - 1

Argumentative Research Paper on Gun Control - Essay Example Americans generally feels that some gun control is necessary, however, people argue to what degree "Control" is necessary without taking their right to keep and own guns, the focus is then, is the right to own a guns is a inalienable right as outlined by the 2nd Amendment, "the right to keep and own a gun should not be infringed upon. Kleck and Kates (2001) have argued that â€Å"handguns are actually used by victims to repel crime far more often than they are by criminals in committing crimes - as much as three times more† (Kleck and Kates p.16). They have also pointed out that â€Å"Liberal allowances of concealed handgun carry by thirty one states have coincided with a reduction of thousands of murders, rapes and other violent crimes in those states† (Kleck and Kates p.17). Many people are of the view that the crime rates in America could be reduced with the help of gun control. They are forgetting the fact that the situation would be worse if the public deprived the opportunity to own a gun for their self defense. Gun control legislatures may prevent the public from owing a gun for self defense; however, these laws may not prevent criminals from owing or using guns for executing their missions. In other words, the absence of guns in the hands of general public for self defense will serve as a bl essing for the criminals in executing their plots easily. It is because of the above fact that public opinion polls consistently show their opinions against gun control laws. â€Å"Most Americans are skeptical that gun control can do much about crime and particularly dubious about the likelihood of disarming criminals through gun control† (Kleck and Kates p.112) â€Å"People also insist even if you do have gun laws it will not help control all the violence. They say there are still knives and weapons that can kill also† (Against Gun Control). Gun is not the only weapon used by people

Preventing Blood Stream Infections Health And Social Care Essay

Preventing Blood Stream Infections Health And Social Care Essay National Patient Safety Goals (NPSG) were introduced in 2002 in order to help address some of the issues that were responsible for causing a majority of the situations that were responsible for creating patient safety issues. These goals were implemented in order to put focus on what were deemed to be the most preventable of these issues. One of these goals is the prevention of central line-associated blood stream infections (Lyles, Fanikos, Jewell, 2009). Literature Review Central venous catheters (CVC) are indispensable in the care of critically ill patients. However, their use is not without risk. Catheter-associated bloodstream infections (CA-BSI) are common healthcare-associated infections in intensive care unit (ICU) patients and have been estimated to occur in 3%-7% of all patients with CVC (Warren, et al., 2006). It is well documented that intravascular catheter related complications are associated with extending hospital length of stay, increasing direct costs and increasing ICU mortality. Clinicians insert approximately 7 million central venous access devices (CVAD) annually in the United States, and of these, 1 in 20 is associated with a CA-BSI, despite the use of the best available aseptic techniques during catheter insertion and maintenance. Overall, an estimated 250,000 CVAD-related CA-BSI occur annually, with an attributed mortality of 12.5% to 25% per occurrence. The national cost of treating CA-BSI equals $25,000 per infection, respecti vely, or $296 million to $2.3 billion in total. While the number of CA-BSI has remained relatively steady, vascular access device use has drastically increased, especially in nonhospital settings (Rosenthal, 2006). A vast amount of research is directed toward reducing these complications in an effort to improve patient outcomes. A review of the literature provides an overview of current recommendations concerning intravascular catheter care and research regarding the use of education programs to promote recommended practice. The Centers for Disease Control and Prevention (CDC) published the Guidelines for the Prevention of Intravascular Catheter-Related Infections in 2002, which is the benchmark for all intravascular catheter care recommendations. The guidelines for CVC suggest the replacement of dressings every 7 days or when soiled or loosened, intravenous tubing changes every 72 hours, and the replacement of tubing used to administer blood products and lipid emulsions within 24 hours of infusion initiation (East Jacoby, 2005). According to the CDC, approximately 53% of adult patients in intensive care units have a central venous catheter on any given day (Rupp, et al., 2005). Skin cleansing of the insertion site is regarded as one of the most important measures for preventing catheter-related infection. Historically, povidone-iodine is an antiseptic that has been used during the insertion and maintenance of the intravascular devices. It works by penetrating the cell wall of the microorganism. More recently, chlorhexidine has been studied and found to be more effective as a skin antiseptic to prevent catheter-related infection. It works in less time, retains its antibacterial effect against flora longer, is not inactivated by the presence of blood or human protein, and causes minimal skin irritation. Chlorhexidine works by disrupting the microbial cell wall. It is active against many gram-positive and to a slightly lesser degree gram-negative bacterium (Astle Jensen, 2005). A multistep process is recommended to prevent CA-BSI that includes: educating staff, using maximal barrier precautions (e.g. a sterile gown and gloves, mask, cap, and large sterile drape), performing infection surveillance, and replacing occlusive dressing every 7 days or when needed (Buttes, Lattus, Stout, Thomas, 2006). Other strongly recommended practices include proper hand hygiene, use of chlorhexidine gluconate for insertion site preparation, and avoidance of routine catheter changes. Catheters impregnated with antimicrobial agents are recommended when infection rates are high or when catheters will remain in place for a considerable time (Krein, et al., 2007). Education of staff on the proper care of CVC is paramount in reducing the amount of CA-BSI. This is perhaps one of the most cost-effective methods of reducing CA-BSI (Ramritu, Halton, Cook, Whitby, Graves, 2007). Implementation A staff education program was initiated for the nursing personnel that primarily deal with CVC. This education program was aimed at training the ICU and step-down unità ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s nursing staff proper care and maintenance of the CVC. Education focused on proper care of the CVC, including when dressing changes should be performed e.g. every 7 days or when the dressing is soiled. Nurses were also trained in how to appropriately assist with CVC placement and the documentation tool that infection control utilizes to evaluate adherence to insertion guidelines. Posters were also placed in the nurseà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s break and conference areas that had educational material related to proper care of CVC. Documentation was also placed in the physicianà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s lounges that encouraged utilization of maximal barrier precautions during CVC insertion. The facility that was observed currently utilizes a few different means of measurement with regards to CA-BSI. First, a checklist is utilized during CVC insertion that evaluates adherence to insertion guidelines by the staff. This checklist is sent to infection control and entered into a database which is correlated with patient data regarding CA-BSI. Second, in patients that are identified as having a CA-BSI, after catheter removal, laboratory microbiological studies of the catheter, blood, and insertion site swabs are performed to identify causality of the infection. Implementation Compared to Literature Suggestions Practices that reduce the risk of CA-BSI include the following: (1) use of maximal barrier precautions during CVC insertion (i.e., a surgical mask, sterile gown, sterile gloves, and large sterile drapes), (2) placement of the catheter in the subclavian vein rather than the internal jugular or femoral vein, (3) changing catheters only when necessary, and (4) changing dressings on CVC exit sites when they become nonocclusive, soiled, or bloody. These practices have been incorporated into national guidelines. Currently, the Healthcare Infection Control Practices Advisory Committee (HICPAC) of the Centers for Disease Control and Prevention (CDC) recommends that hospitals implement comprehensive educational programs that teach proper CVC insertion and maintenance techniques (Warren, et al., 2006). These practices are mostly in line with what is implemented at the observed facility. One difference, which is not in line with these recommendations, is that the observed facility has a high nu mber of internal jugular insertions rather than utilizing the subclavian vein. When asked about this, many of the physicians stated that access was easier to identify utilizing ultrasound during insertion and they preferred this method over subclavian insertion. Recommended Changes First, implementation of an education program for providers that is focused on infection control, especially the recommendation of utilizing the subclavian vein insertion for CVC placement as a first choice in patients that have no contraindications to this placement. Second, procuring the second-generation antiseptic catheter, coated with chlorhexidine and silver sulfadiazine on the internal and external surfaces, to more effectively prevent microbial colonization in patients that are identified as being at risk. Decreased bacterial colonization, a critical step in the pathogenesis of catheter-associated infection, may correlate with prevention of catheter-related bacteremia (Rupp, et al., 2005). Third, education and training needs to be expanded to any nurses that may be responsible for caring for a patient with a CVC. These areas include non-critical care areas such as pediatric and medical floors. Larger numbers of patients with CVC are now found in non-ICUs than in ICUs and that CA-BSI rates in those settings are higher. Catheter types and insertion sites vary greatly among settings. For example, jugular and femoral insertion sites are common in ICUs; subclavian and peripheral sites are more common elsewhere. So strategies for reducing CA-BSI must be tailored to the setting (Hadaway, 2006).

Digital Rights Management

Technological innovation is drastically taking place in almost every field. Experts and engineers put their extraordinary effort to develop software or products that requires some kind of security to protect it from misuse. Digital Rights Management is the one which is used for technologies that controls the use of digital content. With the advancement of Internet and development of digital content, content owners are being impelled into a new arena where they can enhance their rights by using DRM technologies as a way to control the use of their content.The present paper focuses on DRM, argumentative views of various experts on it and effectiveness of DRM in radically changing Hi- tech world. Digital Rights Management (DRM) facilitates copyright holders to achieve value for their works. DRM is used variably in literature. According to Electronic Frontier Foundation, â€Å"Digital rights management technologies are aimed at increasing the kinds and/or scope of control that rights-ho lders can assert over their intellectual property assets.†DRM allows the copyright holder to control the ways consumer’s access and use the holder's work once the work is made available in a digital format. By controlling the access, a right holder is capable to offers an exclusively competent business model and his work will be protected from infringing uses. It is not possible for DRM at its own level to realize these aims because it is susceptible to the hackers, which is able to avoid DRM safeguards. That’s why, law enforcement is required to avert from hackers.These steps will strengthen DRM technology (Christopher D. Kruger, pg: 281). The focus of the first generation of Digital Rights Management (DRM) was mainly on security and encryption as a way of working out the problem of unauthorized copying of the content. It was performed by locking the content and to limit its distribution to only those who make payment. In the second-generation of DRM, major step s to cover the description, identification, trading, protection, monitoring and tracking of all forms of rights procedures over both tangible and intangible assets.DRM deals with all rights and not only the rights applicable to permissions over digital content. There are two significant architectures which must reflect on while designing and implementing DRM systems. The Functional Architecture is the first. This covers the high-level modules or components of the DRM system that together provide a management of rights till the end user. The Information Architecture is the second critical architecture. This covers the modeling of the entities within a DRM system as well as their relationships.In digital rights management, the licensing authority issues to the DRM licensee a certificate and a public/private key pair for use in service. The client will sign the certificate with the licensing authority private key and send it to the content server along with the public key. The content server then verifies the certificate and thereby authenticates the client. The server also checks the certificate with the list of revocation and if so, the client will not be able to receive or decrypt content. There are two algorithms used in signing.The Windows DRM for Network Devices and HDMI and the Open Mobile Alliance use the RSA algorithm. An Elliptic Curve algorithm being much lighter, are used in Windows DRM for Mobile Devices and DTCP. There are number of companies holding patents, which cause some concern for adopters and have delayed the introduction of ECC to wider use in DRM. Once the authentication of a device is complete and it is determined that it has the valid license authority certificate, then in a DRM design, the last step is to decrypt content – the symmetric cipher key. This is obviously very important.Consumers just can not break their head to manage a key for every song or video that they have licensed under a DRM scheme, nor would the owner of a br and new product wish to enter 40 hex digits into the new console before using it. It is to be noted that one tremendously imperative feature of DRM security design is the processes by which secret DRM values are stored. While these consumer electronic products can be accessed by consumers, hackers will pry the design looking for susceptibilities. It is better to use the key storage on chip non-volatile memory.The major problems with this approach are NVM memory is not available in every process, especially the advanced technology nodes, the license fees for NVM are fairly high and last of all the programming of the secret values in off-shore ODMs may encounter a security issue as the secret values are in plaintext (Al Hawtin, Embedded Technology Journal). DRM has many advantages such as one can make more investment in digital content. Digital copies are perfect no matter how many copies are to be made. Large corporations are not the only creators of content.The Internet provides low -cost distribution network globally from which thousands of software producers get advantage. Strong DRM ensures a revenue stream at lower rate. Furthermore, good DRM means more legal free media, and lower prices. (John Carroll, 2002ZDNet). Even though DRM has many positive aspects and it is legally protected, it is always a matter of argument. Debate over the issues of fair use and DRM at the 12th annual Computers, Freedom and Privacy (CFP) conference in San Francisco summarizes that it is too early in this period of technological modernization to begin locking down digital content.Peter Jaszi, law professor at American University's Washington College of Law referred to copyright holders' attempts to keep tight control over their digital content, such as some record companies' moves to distribute DRM-protected CDs that cannot be played on more than one device. But even more threatening to fair-use advocates is proposed legislation introduced by Senator Ernest â€Å"Fritz† Ho llings, which aims to incorporate a built-in copyright protection measure in all consumer digital devices. Most speakers at CFP established that DRM was not the solution to the copyright difficulty.Many of the advocates agreed that DRM would be more successful in harmonizing the rights of user and copyright holders than would be legislation. Stefan Bechtold, a Stanford Law School fellow and author of a book on digital rights management, argued that even though DRM can slow down fair use and free speech, the technology is more progressive than law. It develops speedily and can be installed on an international level. According to Microsoft Security Architect Barbara Fox, DRM technologies make easy to secure the content and setting rules for consumer use but it is much more intricate to guarantee that users have fair use of that content.Further he noted that copyright law is vague when it comes to fair-use rights and DRM would be incapable to settle on whether a user should be able to use content under certain state of affairs (CNN). Even so many controversies, various industries like the entertainment industry, led primarily by the Motion Picture Association of America (MPAA) and the Recording Industry Association of America (RIAA), are dynamically chasing DRM-friendly policy initiatives through federal legislation and regulations, the courts and standards organizations.Music and movies have grabbed most of the headlines around digital rights management (DRM). The â€Å"killer app† for enterprise DRM is document management, primarily for purposes of regulatory compliance. The relevant regulations include the Health Insurance Portability and Accountability Act (HIPAA), the Gramm-Leach-Bliley Act (GLBA) and the Sarbanes-Oxley Act (SOA). These laws require that the confidentiality and/or integrity of certain types of documents be protected (E.John Sebes, Mark Stamp, Pg: 52). DRM is computer code that can be embedded in music and video files to dictate how th ese files are used. The best-known example is the music Apple Computer sells at its iTunes Music Store. Using a DRM system it invented called FairPlay, Apple has engineered its songs, at the insistence of the record companies, so that they can be played only on a maximum of five computers, which means that one can burn only seven CDs containing the same play list of purchased tracks.In fact, obtaining relatively liberal DRM rules from the labels was the key to Apple's success in selling music. But some other uses of DRM technology are not so benevolent. Some CD buyers are discovering to their dismay that new releases from certain record companies contain DRM code that makes it difficult to copy the songs to their computers, where millions prefer to keep their music.People who buy online music in Microsoft's Windows Media format too often run into the DRM error message â€Å"unable to obtain license† when try to transfer the songs to a music player. The theft of intellectual p roperty on the Internet is a real problem. Millions of copies of songs, TV shows and movies are being distributed over the Internet by people who have no legal right to do so, robbing media companies and artists of rightful compensation for their work (WALTER S.MOSSBERG, 2005). The premier provider of smart mobile content retailing solutions, announced the U. S. Patents and Trademarks Office has issued the company a patent in the area of mobile content and applications Digital Rights Management (DRM). To sum up, DRM standardization is now taking place in a number of open businesses. Digital Rights Management is rising as an alarming new confronts, and it is necessary for DRM systems to provide interoperable services.
