Extra-Terrestrial Existence :: essays research papers fc

Has intelligent extra-terrestrial life visited the Earth? Have people actually seen spacecraft from another world? Have these spacecraft abducted human beings and performed experiments on them? Have these spacecraft been recovered by our goverment? Many believe this to be very true. Contrary to these beliefs, there is no physical or any evidence to prove these aliens have visited the Earth. But that does not rule out the existence of intelligent life elsewere in the Universe. There could always be life out there. But way to far away to have visited the Earth. The major reason people believe in aliens is a good reason to believe. This major reason is the sighting of a UFO. UFOs have revolutionized the way people think about aliens. The term UFO means: Unidentified Flying Object. Today the term UFO usually is reffered to an alien spacecraft. These alien â€Å"spacecraft† come in many shapes and sizes. The most common UFO has a disk or saucer shape. They move at very high speeds and appear to spin on an axis. UFO sightings vary from person to person. there have been so many reports of UFO sightings they can’t be counted. But are these sightings really alien spacecraft? The earliest sighting of a UFO is dated back to 213 B.C. Theses sighting were thought to be alien craft. Studies show that these sightings could have been a comet of a meteor. Around 742-814 A. D. "During the reign of Charlemagne, spacecraft took away some of the earth's inhabitants to show them something of the way of life of space people. These events are described in the Comte de Gabalis' Discourses.† Trench 1966. The University of Colorado conducted a UFO report. This elaborate report was lead by Edward U. Condon. Condon states, The decision to etablish this report for the Scientific Study of Unidentified Flying Objects stems from recommendations in a report dated March 1966 of an Ad Hoc Commitee of the Air Force Scientific advisory board set up under the chairmanship of Dr. Brian O’Brien to review the work of Project Blue Book. In this report Condon gives examples of some UFO reports. In 1952, so many UFO reports came in it clogged some Military communication channels. It was believed that an enemy planning a sneak attack could report a bunch of UFO reports to cause mass confusion to the Military communcations. Since 1953 many results of UFO study have been unclassified except when reasons needed to withold evidence because of classified missles or classified radar.

Polymorphic & Cloning Computer Viruses :: essays research papers fc

Polymorphic & Cloning Computer Viruses The generation of today is growing up in a fast-growing, high-tech world which allows us to do the impossibilities of yesterday. With the help of modern telecommunications and the rapid growth of the personal computer in the average household we are able to talk to and share information with people from all sides of the globe. However, this vast amount of information transport has opened the doors for the computer "virus" of the future to flourish. As time passes on, so-called "viruses" are becoming more and more adaptive and dangerous. No longer are viruses merely a rarity among computer users and no longer are they mere nuisances. Since many people depend on the data in their computer every day to make a living, the risk of catastrophe has increased tenfold. The people who create computer viruses are now becoming much more adept at making them harder to detect and eliminate. These so-called "polymorphic" viruses are able to clone themselves and change themselves as they need to avoid detection. This form of "smart viruses" allows the virus to have a form of artificial intelligence. To understand the way a computer virus works and spreads, first one must understand some basics about computers, specifically pertaining to the way it stores data. Because of the severity of the damage that these viruses may cause, it is important to understand how anti-virus programs go about detecting them and how the virus itself adapts to meet the ever changing conditions of a computer. In much the same way as animals, computer viruses live in complex environments. In this case, the computer acts as a form of ecosystem in which the virus functions. In order for someone to adequately understand how and why the virus adapts itself, it must first be shown how the environment is constantly changing and how the virus can interact and deal with these changes. There are many forms of computers in the world; however, for simplicity's sake, this paper will focus on the most common form of personal computers, the 80x86, better known as an IBM compatible machine. The computer itself is run by a special piece of electronics known as a microprocessor. This acts as the brains of the computer ecosystem and could be said to be at the top of the food chain. A computer's primary function is to hold and manipulate data and that is where a virus comes into play. Data itself is stored in the computer via memory. There are two general categories for all memory: random access memory (RAM) and physical memory (hard and floppy diskettes).

Diathesis Stress Model

Diathesis- This is the genetic predisposition which the Genain children expressed through their father. Mr. Genain had various fears and obsessions such as patrolling the house because he was worried of a break in, forms of paranoia. Since paranoia is a symptom of schizophrenia it is likely that Mr. Genain was schizophrenic and he passed this gene onto the children. Later on, his actions created stress that triggered the schizophrenia in his children. Stress: Nora and Myra were considered the more superior set of twins and therefore were able to function better than Iris and Hester. This categorization is probably one of the first stressors that caused Iris and Hester to suffer the worst from the disorder. A stress that affected all of the children and helped trigger the disorder was Mr. Genain’s insistence on watching the girls dress and undress. Furthermore, his molestation of two of the girls made them more likely to develop schizophrenia. Part of the reason Nora was not as successful as Myra was because she was her father’s favorite sexual target which added more stress to her life. Another stressor that hurt Iris and Hester was when their parents had their clitoris’s were circumcised. Also, since Iris, Nora, and Myra began deteriorating after a man made improper advances this proves that stress played a prominent role in the signaling of schizophrenia. Myra was able to be the most functioning individual because she was her parent’s favorite and received the least objectionable attention, and therefore had the least amount of stress in her life.

Lung Cancer Detection Methods

There are several ways in which lung cancer may be detected and some of these are the following: First of all is to have the patient undergo what is technically referred to as â€Å"screening† (The Health Alliance, 2006, n.p.). Here, a series of laboratory tests and other examinations are carried out (The Health Alliance, 2006, n.p.). Second is known as blood test (The Health Alliance, 2006, n.p.). Here, the blood is placed under scrutiny to see if the â€Å"lung cancer† has multiplied and have already reached the patient’s liver or bones (The Health Alliance, 2006, n.p.). Third is the â€Å"bone marrow biopsy† wherein a needle is utilized to take out a small portion of the bone located at the â€Å"back of the hip bone† and is placed under the â€Å"microscope† to see if any cancer cells may be detected (The Health Alliance, 2006, n.p.). Fourth is technically referred to as â€Å"mediastinoscopy† (Harvard University, 2008, n.p.). Here, the neck is incised to allow a lighted pipe to go through and to eventually get a sample of tissue inside it (Harvard University, 2008, n.p.) Again, this will confirm if cancer cells are there or not by looking at it under the microscope (Harvard University, 2008, n.p). Fifth is known as â€Å"bronchoscopy† (The Health Alliance, 2006, n.p.). Like the aforementioned fourth detection method, a lighted pipe is involved here as well (The Health Alliance, 2006, n.p.). However, with this method, the tube will be inserted on the nose and will look for tumors or obstructions in the lungs (The Health Alliance, 2006, n.p.). It may also take tissue samples or fluids so that it may be checked under the microscope for cancer cells’ presence (The Health Alliance, 2006, n.p.). Last but not least is technically referred to as â€Å"needle biopsy† (Radiological Society of North America Inc., 2008, n.p.). Here, the lungs are monitored through a machine known as â€Å"CT Scan† while a needle is utilized to take out a mass sample in the lungs (Radiological Society of North America Inc., 2008, n.p.).Like in the other methods, the aforementioned sample will have to be checked under the microscope (Radiological Society of North America Inc., 2008, n.p.).

Negative Effects of Social Media Essay

Social media has had made many impacts on society. Any website that allows social interaction is considered a social media site (Schurgin O’Keeffe, Clarke-Pearson). Due to the new technology taking over, social media has been easier than ever to get a hold of by the applications that have been made for portable devices. Through these devices and applications, being socially connected has made it easier to communicate with each other. Unfortunately, it all hasn’t been positive communications. There are many negative effects of social media, the biggest being addiction and self esteem. The definition of an addiction according to the Merriam-Webster Dictionary is: an unusually great interest in something or a need to do or have something (addiction). While social media addiction is not clinically diagnosed at this point, the behavior displayed and language of the students use suggests that society is not that far from becoming physically dependant on mobile devices (Westfa ll). With the new technologies right at the fingertips of society and easy access to check the newsfeed of the word, addiction to social media is on the rise. There are many factors that classify someone as an addict in different parts of the world. According to psychology professor and author Larry Rosen, â€Å"Social media addicts spend most of their waking moments checking for updates, chatting in instant messaging rooms, posting updates and checking their friend’s latest postings. Even when they delete their accounts, they usually are driven to make new accounts within twenty-four hours† (Gabriel). Some cases of addiction to social media are not as severe as others. In some extreme cases there are symptoms that can be observed. These symptoms include: spending at least four hours per day using social media, canceling more and more activities with family, friends or coworkers, bringing cell phones or other internet capable devices into the bathroom, and feeling anxi ous when you cannot get onto the internet. Once the individual has gotten involved in networking sites, things can escalate quickly. One reason these sites are so addictive is that there is a nonstop stream of messages, photos, updates and information coming from those in the network. If you have ten friends, it should not be a problem keeping up with them. If an individual’s network is one hundred friends or more, the individual might end up online for hours  every day, trying to check all of the updates. Trading messages back and forth with other members, the individual might find himself or herself even more caught up in the exchange, just as it would be in a normal conversation. see more:speech on social networking Social networking sites are meant to be casual, relaxed ways to connect with others. If you start losing sleep or are unable to concentrate because you’re always thinking about going online to check your friends’ statuses, then that is a sign of trouble. Social media has become an addiction to people because it is a form, or a way, to escape reality. It is also a way that someone can create their own cyber reality (Cosper). According to an associate professor in a program of science, technology, and society, Natasha Schull states, â€Å"Online games and social networking sites use psychological principles to keep you hooked† . Recent study shows that online dependency is not so different from a physical addiction. â€Å"MRI scans of patients checking their social media feed and those using cocaine look exactly the same,† says Schull. Most addictions begin as a harmless satisfaction of needs and desires; checking a few media sites stimulates those pleasure centers in the brain (Jensen). Another reason these sites are so addictive is that they provide outlets for when you are feeling down. People post fewer negative than positive updates on networking sites. They might mention trips they have taken or new cars, but they will rarely mention when they get poor grades or if they gained twenty pounds. If the individual’s own â€Å"real† life is not going so great, they can always go online and pretend it to be better. This in most cases, is how depression from social media usage is started. It is easy for someone to lose himself or herself in what experts say, â€Å"happyland† and forget about the hurdles in everyday life (Bocco). With new studies there has been known to be at least ten different types of social media addiction. A few of these types of addiction are: â€Å"The Alert-Lover†, â€Å"The Social Guru†, â€Å" The Verb Creator†, â€Å"The Blog Referencer†, â€Å"The Multi-Mayorâ € , and â€Å"The Freak Out-er† (Laird). Just like any other addiction, social media addiction is a disease. Social media addiction can become a destructive compulsive habit which as with any addiction can lead to broken relationships, job loss, and even financial issues. Individuals addicted to social media often feel anxiety or even may feel physically ill if not able to connect to the internet or their favorite social media sites. Evidence suggests that that the typical addict is  usually a teenager, usually male, and has no social life outside of their computer and or mobile devices. Though this is not truefor all. This disease has been known to affect millions of people all over the world. The most important being the â€Å"constant checker† and the â€Å"vowel hater† (Laird). In today’s world, checking social media on a regular basis can be easier than ever before. For some, this great access is not all that great. Those people are known as the â€Å" constant checkers†. They feel the need to check their handheld devices on a regular basis to feel up-to-date on the newest news that they may have missed, in what they may feel, has been a very long time. A study done by the University of California suggests that on average, study subjects check their mobile devices thirty-five times out of habit. It was also shown that nearly eighty- eight percent of teenagers and young adults check their news feed before even getting out of their bed in the morning. Through this study those subjects then realized that they were losing the relationship s that they have had with the people closest to them because they were being annoying. Some, but not all, of those studied admitted to having a physical attachment to their mobile devices and having withdrawls when taken away. Lisa Merlo, a psychologist at the University of Florida, says, â€Å"If you hear ‘put the phone away’ more than once a day, you probably have a problem† (Cohen). Another type of social media addiction is being a â€Å"vowel hater†. These people are known to take out every vowel possible in order to save time and space in either a text message or posting onto any form of social media site. This addiction has been known to alter all parts of the individual’s specific speech. It alters their speech in regular conversation and those electronically. From it leaking into the regular everyday conversation it can cause confusion to those around. Some may not know all the up to date slang terms that are used in instant messaging and so cial media. The same is for electronic messaging. This could be email or instant messaging on a media site. The most common type of people that this kind of addiction has been found is the younger generation. This is the age group of those from the age thirty to seventeen. It has been found that the younger the individual the more vowels are taken out of each word in each sentence. Some of the most noticeable symptoms of being a †vowel hater† is when posting on a social media site, such as Twitter, they are known for dropping vowels just to reach the one hundred forty character  limit (Hivesocial). Like any other disease there are a variety of treatment options. These treatment option vary from AA type meetings to meetings that can be held via webcam, other instant messaging alternatives or sometimes even a therapist. Unlike drug or alcohol addiction there will be no physical side effects from lowering your usage and stopping completely. The individual will be battling behaviors that have built up over time so it will be difficult to cut back on social media time. However, it is extremely doable. One of the first steps in addiction treatment is the individual must admit to himself or herself that there is a problem. Once the problem is recognized it is best that the subject take note on which kind of social media or technology that are addicted to. This may be hard for the individual for they in most cases, do not realize that they are checking their mobile devices and social media sites. Therapy can give the individual a tremendous boost in controlling internet use. Cognitive-behavioral therapy provides step-by-step ways to stop compulsive internet behaviors and change the individual’s perceptions regarding internet, mobile phone, and computer use. Therapy can also help you learn healthier ways of coping with uncomfortable emotions, such as stress, anxiety, or depression. Joining a support group is also another great way to help the addict make them feel like they are not alone. Ironically, some of these support groups are online which may not be too supportive to those who have a heavy addiction. Which in some cases should be monitored carefully (Sherwood). Research from the University of Buffalo indicates that women who base their self worth on their appearance are likely to post more pictures of themselves online for validation and to have larger social media networks (Henderson). Positive comments on social media can and do boost self esteem. Some people get a boost of healthy self esteem and get ego driven self love based on how many â€Å"Likes† they get on a social media site. Everyone wants to feel worthy of love and belonging. In some ways, the â€Å"Likes† we get on social media sites satisfies this need in almost a distorted way. Perhaps we are looking for love, or †Likes† in all the wrong places. According to lead author Elliot Panek, â€Å"Among young college students, we found that those who scored higher in certain types of self worth posted more often on Twitter. But among middle- aged adults from the general population, those that had more self love posted more frequent status updates on Facebook† (Bergland).  Fac ebook serves self loved adults as a mirror. As for a middle- aged adult, these findings of the difference between Facebook and Twitter may be influenced by a generation technology gap. Panek says of Facebook, â€Å"It is about creating your own image, how you are seen, and also checking on how others respond to this image.† Many middle-aged adults have already formed their social selves. They use social media to gain approval from those who are already in their social circle. For some self loved college students, the social media is a tool for them in helping them reach there wanted social standings (Bergland). Along with being addicted and having a low self esteem there is yet another negative effect of social media, cyberbullying. Access to electronic devices like smartphones that capture photos, videos and have the ability to upload to video sites or be sent through a mass messages within seconds mean the bullying never ends. Reports of teens recording fights, sexual assaults and more have been in the news with several being caught after sharing it on their Facebook pages. There are even sites dedicated to publishing and promoting teen fight videos which does not warrant a link. Teens already dealing with the pressures of fitting in now have to fear being targeted by bullies, who can easily smear their reputation with a few clicks of the mouse. The most dangerous part is this content lives on well after the damage is done, a daily reminder to the victim. Most commonly cyberbullying is found on chat sites and social media that has had a huge boom within ten years or less such as Facebook. MySpace, LinkedIn and Twitter. It is easier for the bullier to pick on their victim because they are not talking to them di rectly. In fact, in almost all cases it is not face to face but rather, typed, hateful words. Saying hurtful words is not the only form of cyberbullying. Cyberbullying can also be done through impersonation. Impersonation means that the person does not even have to know the individual that is bullying them. These types of online harassments should not be taken lightly. Many teens and even professionals have been known to quit what they love or even in severe cases, have committed suicide. On average, those that are bullied tend to all have the same or nearly the same symptoms. Those symptoms include: skipping school, experience in-person bullying, be unwilling to attend school, receive poor grades, have lower self-esteem, have more health problems, and the used of alcohol and drugs. Cyberbullying is different from any other kind of  bullying because it can reach the individual at any time of the day, any time of the week (Social Media Makes Cyberbullying More Dangerous). Granted, not all cyberbullying is no all done on Facebook, but since the social networking site is so popular among tweens and teenagers everywhere, it is a regular source of problems. Nearly half of all teenagers in the United States have experienced some online bullying, according to statistics from the National Crime Prevention Council. Twenty percent of middle school students said they have seriously thought about suicide due to online bullying, according to a recent survey conducted by the Cyberbullying Research Center (Levine). It doesn’t take a scientist to figure out that victims of cyberbullying have lower self-esteem than those who have not experienced it. On the other hand, research has also surprisingly shown that the actual cyberbullying offenders have lower self-esteem than their peers. It would seem that when it comes to bullying, everyone loses. Since low self-esteem has been linked in many studies to poor grades in school, health issues, excessive absences, and crimin al behavior, it would be in everyone’s best interest to take steps to shut bullying down early on. Addiction and self esteem are some of the many negative effects of social media. In review, addiction not only hurts the individual but also how the individual acts and may participate in events. Not only does it hurt them but it also hurts the relationships that they are in. This includes family, friends and co-workers. Addiction also can play a role in how they treat people on a day to day basis. From being addicted to social media the individual can start to lose their sense of how to communicate with others face to face. Luckily, with this understudied addiction there are treatment options that are beginning to take place for those that would like to take a stand on their addiction. Self esteem is also a negative factor in social media today. Those individuals that have a higher and possibly lower self esteem tend to post more online than those that do not. This is dependant on how much self worth an individual may have for him or her self. Some people keep posting online just he lp themselves boost their self esteem because they may have a hardship outside of the â€Å"cyberworld.† In that case, for some the only way to boost their self esteem is to cyber bully others. Impersonation is one of the more common types of cyberbullying because the individual does not have to know the victim on a personal level or even at all. Addiction and self  esteem are only a few of the numerous negative effects of social media. Works Cited â€Å"addiction†. Merriam-Webster.com. Merriam-Webster, 2014. Web. 14 January 2014.

Module discussion

Organization Priorities Identify the current health policy priorities for your state nurses association. Identify the benefits that could come to you, your community, health care consumers in the district, and other members of the nursing profession if proposed priorities were supported. Develop a plan of action to educate your state senators and representatives about these priorities. The Florida Nurses Association (FAN) Is Involved In a couple legislative related projects that I found on their website.Firstly, I found the Fan's position on the expansion of Medicaid. In the document provided on their website there Is lot of background Information on Medical and how this would affect the population (FAN, 2012). While this legislative topic has already been addressed, I still thought It would be useful to discuss. I found another bill, H. R. 5113, which alms to end the Increased federal funding for Medicaid expansion with respect to Inmates hospital care under the Patient Protection a nd Affordable Care Act (FAN, 2014).As the FAN already supported the expansion, I find this would contradict their previously stated position on Medicaid expansion. Personally, I do think this bill should be supported. As a nurse, I cannot see the fairness of removing coverage of individuals who are inmates. To educate my state senators and representatives on my position, I would plan to write them a letter. I would write my letter Just as we did for one of our assignments. After that assignment I feel as though I can accomplish a lot more than I could before hen it comes to writing professional letters.

Infrastructure Protection Essay Example | Topics and Well Written Essays - 750 words

Infrastructure Protection - Essay Example The Homeland Security is responsible for the coordination of the nation’s overall protection efforts expressed by NIPP and the SSP. The homeland security watches and directs the development, integration and the NIPP with the national preparedness initiatives. The NIPP and the SSP therefore relies on homeland security department for success in implementation of their plans towards achieving infrastructural security in the nation. This is therefore how the three departments relate with one another and each of them is quite essential for the development of tight infrastructural security in any nation (National Infrastructure Protection Plan, 2015). Every Sector-Specific Plan is developed by a Sector-Specific Agency with a purpose of providing information on the application of concepts borrowed from the NIPP to the special characteristics and conditions of their sector. These Sector-Specific Plans are undergoing updates to make them work effectively with the most recent NIPP. An example of an effective SSP is the Information Technology sector-specific plan. The Information Technology Sector-Specific Plan (ITSSP) provides details of the efforts made by the IT department in managing the national level risks experienced in the nation. It provides the information on its progress and how promising these efforts are in managing the risk. This includes the details on the completion of the IT sector Baseline Risk Assessment. The IT SSP is also expected to make a presentation on how the IT department is making use of the results from the baseline analysis to inform the sector’s infrastructure and key resources (CIKR) protective p rograms, development, research, and measurement activities. For the sake of maximum protection of its critical infrastructure, the IT SSP provides updates each year on the details required. In the past years, the sector has also accomplished a few missions here and
