Visual Prostheses and the Retinal Implant Project :: Biology Essays Research Papers

Visual Prostheses and the Retinal Implant Project Visual percepts are the final product of a rich interplay of stimulus processing that occurs without the intervention of one's consciousness. While this is a fascinating issue to consider, especially as it pertains to the philosophical and practical definitions of ideas like the "self," the converse is equally interesting to me. In this modern era of exploding technological ingenuity, the sum of which is a product of the conscious brain, increasingly more opportunities exist for the brain to design the input it receives. One method by which this occurs is observable in the treatment of visual pathologies. A development of particular interest to me is the use of visual prosthetic devices in the treatment of some forms of progressive blindness. Research in this area raises numerous conflicts within the realm of bioengineering, but promises, at least, to challenge the boundaries of current microtechnology and instigate further integration of the rapidly expanding fields of electronics a nd medicine. In 1988, a multidisciplinary research team called the "Retinal Implant Project," spanning the knowledge bases of Harvard Medical School, the Massachusetts Eye and Ear Infirmary, and the Massachusetts Institute of Technology's Department of Electrical Engineering and Computer Science, was formed with the explicit goal of creating an intraocular retinal prosthetic device to combat the effects of certain types of progressive blindness (4). The prostheses are intended to stimulate retinal ganglion cells whose associated photoreceptor cells have fallen victim to degradation by macular degeneration or retinitis pigmentosa, two currently incurable but widespread conditions (2). Their most recent work has been to orchestrate short-term clinical trials in which blind volunteers receive a temporary intraocular prosthetic implant and undergo a series of tests to determine the quality of visual percepts experienced over a two- to three-hour period (2). The leaders of the Retinal Implant Project, while enthusiastic about their progress, do not anticipate the realization of a workable prosthetic within the next five years (2). The goal of retinal prosthetic proposed by the collaborators is to bypass degenerate photoreceptors by providing electrical stimulation directly to the underlying ganglion cells (2,3,4,5). The ganglion cell axons compose the optic nerve, which travels from the eye and terminates in various regions of the brain, where the combined input is processed along multiple routes and ultimately results in the experience of sight (4). Ganglion cell excitation will be accomplished by attaching a two-silicon-microchip system onto the surface of the retina, which will be powered by a specially designed laser mounted on a pair of glasses worn by the patient (4,5).

Big D :: Personal Narrative Disabilites Papers

Big D A couple weeks ago, exactly four days after Christmas, I woke up thinking about my uncle Dennis. I loved him very much, but I have never woken up thinking about him. After a few minutes, I realized that three years ago, exactly four days after Christmas, was the day he died. My uncle Dennis was an unforgettable man. He had sparkling blue eyes and a sweet smile. When he laughed everyone else in the room couldn't help but join him. That's not what made him unforgettable, though. Dennis was tall, around 380 pounds, and anoxic; he had brain damage. He never learned to cook, ride a bike, or properly operate an appliance. He required 24-hour a day care from the time he was born until the day he died at age 40. This is not an exaggeration. If Dennis was awake and no one was around to stop him, he consistently caused trouble. Forty years ago, fetal heart monitors were not routinely used in the labor room. Today, a heart monitor aids in the detection of problems such as a pinched umbilical cord, which what caused Dennis's brain damage at birth. Because the pinched cord was not detected, a cesarean section was not performed, and Dennis entered the world mentally retarded because not enough oxygen reached his brain during the birthing process. The small part of the world he entered was Milwaukee. My grandparents had a house which has since been torn down and replaced by projects. In the early fifties about 60% of the residents were black. A large portion of the rest were immigrants. My grandparents were from northern Wisconsin. My grandfather was then working as a boilermaker engineer in a tannery downtown. In addition to staying with Dennis, my grandmother stayed at home with my Uncle Mike, 3; my mother, 2; and my Uncle Tom, 1. Four more children would soon follow. The youngest, Patrick, had Downs' Syndrome. Eleven cousins lived just down the block. A house of prostitution was across the street. Saturday was laundry day. The three older children would eventually be hired as babysitters for Dennis. On Saturdays they would keep an eye on Dennis and play in the backyard while my grandmother did the week's wash. At the end of the day the three young nannies got to split a dime between them at the grocery store on the corner.

Ethics and Utilitarianism Essay

What is Utilitarianism? Utilitarianism is an ethical framework for effective moral action. It’s a philosophical concept that holds an action to be held right if it tends to promote happiness for the greatest number of people. The essence of utilitarianism is in its concept of pleasure and pain. It defines the morally right actions as those actions that maximize pleasure or happiness and minimize pain or evil. Utilitarianism is all about making the right choices that will consequently promote the greatest amount of happiness. It can be traced all the way back to the ancient Greek philosopher Epicurus, but the name most frequently associated with utilitarianism is that of Jeremy Bentham. According to utilitarianism, we should evaluate an action by looking at is consequences, weighing the good effects against the bad effects on all the people affected by it. If the good outweighs the bad, it tends to be a good action; if the bad outweigh the good, it tends to be a bad action. (DeGeorge 45) Ethical principles and theories are the foundations of ethical analysis because bring significant characteristics to the decision-making process. Every single theory shows different points such as predicting the outcome and following one’s duties to others in order to reach an ethical decision. But an ethical theory can only to be useful if the theory is directed towards a common set of goals. Ethical principles are the common goals that each theory tries to achieve in order to be successful. These goals include beneficence, least harm, respect for autonomy and justice. Using utilitarianism in ethical business practice would consider the good and bad consequence for everyone the action would affect, treat everybody as having equal rights, with no bias towards self, and would use it as an objective, quantitative way to make a moral decision. Utilitarianism should be employed in all business decision-making process to maximize effects and minimize negative outcomes. Businesses seek to make a profit. The cost-benefit analysis is a form of utility calculation. Most business often use cost-benefit as a decision making tool. Companies attempt to find out how much something is going to cost them before taking any actions that should result in consequences favorable to everyone involved. Just simply put, the company could make a profit while the consumer benefit from the product. To understand the definitions and concepts of the theory, in relation to business ethics, I will use the Ford Pinto Case as an example. The Ford Pinto was sold with dangerous design faults in the fuel tank in which management knew the problem existed. (bizcovering) In a roll over, the fuel valve had a tendency to leak fuel. That did not stop design and production, they rushed to assemble the vehicle and costs were kept low in order to sell the auto for $2,000. It was successful, until one year four people died and one little boy horribly burned and disfigured. Then there were many other incidents that resulted in Ford being sued and had to pay millions in compensation. The cost-benefit analysis demonstrated an abuse of utilitarian principles to suit their needs, because the engineers were aware of the flaws, yet the company continued to sell the car without safety modifications. Utilitarianism, far from being a self-serving approach to moral issues, demands careful, objective, and impartial evaluation of consequences. This philosophy is based on the belief that the moral and ethical value of one’s action should be judged by the consequence of such action. But utilitarianism states that the morality of an action is best judged by the utility or usefulness of such an action. During the 1980’s, Oliver North had to explain why he lied to congressional committees about his role in the Iran-Contra affair, the sale of U. S. arms to Iran for the release of hostages that were held by Iran, he replied, â€Å"Lying does not come easily to me. But we all had to weigh in the balance the difference between lies and lives. North’s conduct was an example of utilitarianism, his method of justifying his acts of deception is a form of moral reasoning. So long as a course of action produces maximum benefits for everyone, utilitarianism does not care whether the benefits are produced by lies, manipulation, or coercion. Utilitarianism was once a radical philosophy. It attempted to set forth a moral system apart from divine revelation and biblical morality. Utilitarianism focused on results rather than rules. But now has been embraced by so many simply because it seems to make a good deal of sense and seems relatively simple to apply. It provided for a way for people to live moral lives apart from the Bible and its rules. Logic rather than obedience to biblical principles guides the ethical decision-making of utilitarianism. While Jeremy Bentham developed his ethical system around the idea of pleasure and built it on ancient hedonism which pursued physical pleasure and avoided physical pain; John Stuart Mill modified this philosophy and developed it apart from Bentham’s hedonistic foundation. Mill used the same utilitarian calculus but instead focused on maximizing the general happiness by calculating the greatest good for the greatest number. Whereas Bentham established act utilitarianism, Mill established rule utilitarianism. Act utilitarian holds that each individual action, in all its concreteness and in all its details, is what should be to the utilitarian test. (DeGeorge 47) Rule utilitarian holds that utility applies appropriately t classes of actions rant than to given individual actions. (DeGeorge 48) According to Mill, one determines what is right by comparing the consequences of all relevant factors of diffeerent rules for a specific circumstance. In conclusion, utilitarianism is all about making the right choices that will consequently promote the greatest amount of happiness for the greatest number of people. Work Cited DeGeorge, Richard T.

Concept Of Promoting Healthy Ageing Health And Social Care Essay

Ageing is non an event that can happen over a period of clip but a procedure which begins at construct and continues throughout the life ( Crandell 1980 ) . Harmonizing to Cheng ( 2006 ) & A ; Baltes ( 1990 ) , ageing is more than the series of biological alterations. Ripening can be defined by gender, category, societal standing, and civilization instead than twelvemonth alone.Ageing is an inevitable and irreversible procedure ( Brown 1994 ) . Shukla and Brooks ( 1996 ) province the constituent of successful ripening. Harmonizing to them successful ageing depends in the capacity of the person to accommodate, version to alterations in the bodily map, to relationships and to alterations in outlook and resources. The paradigm definition of healthy ageing harmonizing to Lin ( 2006 ) , as healthy independency, household, fiscal security, life adaptation, personal growing and friends/relative relationship. Harmonizing to single perceptual experience, ageing is regarded as something unplea sant, utile, and unneeded and above all, unwanted ( Mesec,2000 & A ; ; Zupancic,2004 ) Rountree ( 2010 ) describes the ageing procedure. Rountree ( 2010 ) in his article told that as the age increases, the organic structure bit by bit loses the ability to react to environment abuses. This lead to effects on a cellular and molecular degree, such as dislocation of cell organs, membranes and enzymes in the organic structure. In the scientific term, this biological procedure of ripening is called Senescence. Senescence leads to loss of organ revere ; diminishing the ability to react to emphasize ; loss of flexibleness ; decelerating of cognitive procedures ; degenerative joint disease ; diminishing centripetal sharp-sightedness ; loss of tolerance to trouble or temperature alterations ; impaired alimentary soaking up ; worsening immune responses and other alterations. These Physiologic alterations in bend, consequence in an increased hazard for common disease, such as coronary artery disease, diabetes, dementedness, malignant neoplastic disease, degenerative arthritis ( OA ) , autoimmunity and others. Rountree ( 2010 ) describes the assorted internal and external factors that leads to Aging. In molecular degree, everybody tonss of tissue, mundane tonss of tissue harm takes topographic point. This all consequences in the release of free groups. Further will damage DNA and the delicate membranes in our cells and cell organs particularly chondriosomes. The Elaborate system of enzymes will assist us to neutralize free groups and mend the harm to our cells and tissues. As age increases the system of enzymes become inactive and familial look of these enzymes diminutions. This all consequences in relentless weariness, decreased staying power, stiffness and achings and strivings that occur after reasonably everyday exercising. External factors include things like fume, firing organic stuffs, ultrasound ( UV ) radiation and other signifiers of ionising radiation. Even medical look into up or testing trials such as X raies, bone scans and computed axial imaging ( CAT ) scans generate free g roups that will ensue in harm of tissue, which leads to long term effects ( Rountee,2010 ) . Rountee ( 2010 ) besides states that presences of sugar/glucotoxity is besides one of the factors that causes ageing. Every clip we eat tonss of sugar, the chondriosome leaks alots of free groups that damage tissue. Besides, high degree of fruit sugar are converted in the liver to triglycerides. These triglycerides normally pack the liver with fat and hence interfere with insulin sensitiveness. So, glucotoxicity and lipotoxicity will take to increased redness in the organic structure. When we are immature, the inflammatory procedure heals rapidly. The relentless low- class redness induced by bad diets and unhealthy life style actively contributes to the wear and tear of the system over clip ( rountree,2010 ) . It means toxic chemicals and metals are the root cause of accelerated ripening. Westendorp ( 2006 ) states some of the reasons/ factors that lead to additions in chronic lessening. They are increasing life anticipation along with better sanitation, interventions for infective d isease, and improved entree to medical attention, understanding of wellness hazards and modified hazard factors. Research based lifestyle recommendations to keep physical and cognitive verve include womb-to-tomb acquisition and rational stimulation, regular exercising, ongoing societal activities, emphasis reduction patterns, sound slumber with graphic dreaming ; emotional fluidness and look ; regular sexual activity, optimum nutrition with appropriate Calories intake. Kaw & A ; Colleagues ( ) stated that the mortality hazard for people who are non tobacco users, who exercise on a regular basis, have a moderate intoxicant consumption and who have a plasma Vitamin C & gt ; 50 mmol/L ( bespeaking fruit and vegetable consumption of at least five helpings a twenty-four hours ) was the equivalent of being 14 old ages younger in chronological age, compared with people who engaged in none of these behaviors. So that means by following simple four things like exercising, make non smoke, devour low to chair sum of intoxicant, eating an copiousness of fruits and veggies in their repasts will assist to be tter their opportunities of life thirster and healthier In the scenario, Dorris wellness was all right before the decease of her hubby. She has enjoyed comparatively good wellness over the old ages and have no important episodes of sick wellness. Used to make house keep plants. But after the decease of her hubby she lost involvement, finds hard to get by with mundane life. Dorris wellness was deterioting as she was non eating decently, non keeping hygiene, non making any activity. She has besides become physically frail and was sing mild confusion and freak out. Dorris should be explained the significance of self-care. Traditionally, self-care is defined as activities associated with wellness publicity ( Backman, Hentinen 1999 ; Backman, 2003 ) . She should be encouraged to take part in activities of day-to-day life, such as exercising, nutrition and relaxation, in order to advance or reconstruct their wellness. Stanner and Denny ( 2009 ) has summarised the cardinal findings in relation to some common diseases in ulterior life and provides an overview of dietetic steps that can be put into advancing healthy ripening. Kirkwood ( 2006 ) associated the biological alterations with ageing as a consequence of a long life accretion of molecular harm in the cells and variety meats that constitute the human organic structure, finally interrupting the cells ability to do the energy they need to work. Kirkwood ( 2006 ) besides province that cistrons and perchance foods supply can act upon fix to this harm and diet, lifestyle and environment all have the possible to determine the rate at which harm to cells is accumulated. Harmonizing to National Statistics ( 2004 ) , the morbidity informations from the UK general study indicated that, in 2004, prevalence rates of bosom and go arounding system status were 340 per 1000 population for grownups aged 75 old ages and over compared with 280 per 1000 population. The prevalence rate of long standing musculoskeletal conditions were 296 per 1000 population for grownup aged 75 old ages and over, compared with 274 per 1000 population for grownups aged 65-74 old ages ( Office for National Statistics 2004 ) .National Health Service ( NHS ) ( 2007 ) estimated that about 6 in 100 people over the age of 65 will develop some grade of dementedness and this figure increases to about 20 in 100 among those over the age of 85 old ages. Coronary Vascular Disease ( CVD ) and shot are the major cause of decease in aged work forces and adult females ( Stanner and Denny 2009 ) . That means ripening is clearly an of import hazard factor. The younger age group have the similar hazard factor as the older grownups because of fleshiness, dyslipidaemia, Hypertension, smoke, low degree of physical activities and diabetes ( Stanner 2009 ) .World Health Organisation ( 2003 ) clearly mentioned that the diet for the people who have an increased hazard of developing CVD and other chronic disease. That includes diet that is energy-dense, high in fat and salt and low in complex saccharides, fruits and veggies. Stanner ( 2005 ) advised some important nutrient material that will assist in protection against CVD. They are integrating non-hydrogenated unsaturated fatty acids as prevailing signifier of fat, whole grains as the chief signifier of saccharide, an copiousness of fruits and veggies, equal Z 3 fatty acids and non excessively mu ch salt. Besides with diet physical activity, reasonable imbibing wonts, turning away of smoke and care of healthy organic structure weight may forestall bulk instances of CVD in western population. Cognitive diminution is besides the most common disease that occurs in the ulterior portion of life. It means mental damage and dementedness ( Stanner 2009 ) . It occurs as the consequence of chronic degenerative encephalon disease. It has a great impact on a individual liberty and independency. That ‘s why there is a great demand of forestalling or proroguing cognitive damage ( WHO, 2002 ) . By following many facets of life styles including the increased physical activity rational mental stimulation, turning away of smoke and assorted facets of life have been associated with healthy ripening ( Clarke, 2009 ) . The hazard of cognitive diminution and shot include high consumption of Na ( salt ) , fat, energy and intoxicant. Stanner and Denny ( 2009 ) province that under nutrition and nutritionary lacks in older grownups besides are a beginning of concern in relation to cognitive diminution. The Hazard of Dementia and Alzheimer ‘s disease increases as the addition in the de gree of sulfur incorporating aminic acids additions. To forestall the hazard of Alzheimer ‘s disease the Mediterranean diet, which contains plentifulness of fruits and veggies, leguminous plants, unsaturated fatty acids and fish, can be helpful ( Scarmeas, Stern & A ; Tang, 2006 ) . Osteoporosis and arthritis are besides one of the jobs that ageing people has to endure. Stanner and Denny ( 2009 ) mentioned the consciousness sing the bone wellness and bar in osteoporosis. As current figures estimate that one in three adult females and one in 12 work forces over the age of 55 old ages will endure from osteoporosis. In order to forestall osteoporotic break, equal consumptions of Ca and vitamin D are cardinal to guarantee optimisation of peak mass attainment ( Loveridge & A ; Lanham – New, 2009 ) . Lack of vitamin D position is besides one of the causes of falls ( Finch & A ; Doyle, 1998 ) . A diet that contains equal protein and vitamin K is rich in fruits and veggies and low in salt may besides assist to detain bone ageing. Avoiding fleshiness will assist in order to forestall degenerative arthritis and weight loss will move as an effectual manner of cut downing hurting and disablement in patients with knee degenerative arthritis ( Dieppe, 2009 ) . Oral wellness is besides one of the of import points to be kept in head to advance healthy ageing. In the UK 58 % of grownups aged 75 old ages and over have no natural dentitions and rely on dental plates ( Steele, Sheiham & A ; Marcenes, 1998 ) . The older people holding tends to eat un healthy diet holding low in fruit and veggies, low in of import foods such as vitamin C and potentially higher in fat ( Walls, 2009 ) . There are so many factors that will in tooth loss. One of the most common grounds is nutrition on dentitions that result in development of dental cavities and therefore consequence in tooth loss ( Moynehan & A ; Petersen, 2004 ) . The frequence of sugar consumption ( in the signifier of sugar incorporating medical specialty ) is one of the common grounds of holding dental cavities. That ‘s why dentist normally recommended restricting consumption of sugar incorporating nutrients and drinks to four occasions per twenty-four hours ( Moynehan & A ; Petersen, 2004 ) . Besides some minerals such as Ca, Zn, Mg, Sr and fluoride are involved in remineralisation of dentitions and can assist protect against cavities. Besides Fe, vitamin B12 and foliate may assist in building in the immune system and assist them from unwritten infection and protect unwritten wellness. In the scenario, Dorris have age of 87years.She is populating entirely. Her hubby died some 6 months ago because of MI Core. Earlier when she was populating with her hubby the wellness was good. As shortly her hubby died, she was non at all making anything merely sitting on the chair. She was non at all taking attention of her nutritionary position. She lost 13 kilogram of weight in the past 6 month. Her hubby had a history of MI Core. So she must be advised sing the diet healthy for her bosom, as she is excessively holding a hazard of holding CVD. The diet must incorporate energy-dense, high in fat and salt and low in complex saccharides, fruits and veggies. Besides, she must be encouraged to take part in physical activity, reasonable imbibing wonts, turning away of smoke and care of healthy organic structure weight.

Men vs women

Men vs.. Women Along the last centuries women have fought to be treated as equals to men. They have tried to have the same opportunities, the same rights and to fulfill the same roles. The battle between sexes seems to have ended some decades ago. As a result, in modern times the lives of women and men are similar as regards responsibilities and privileges. But being born a woman I have always thought that the sole fact of being a man could make my life easier in different aspects. To start with, men grow old with more dignity than women.Wrinkles, grey hairs and beer bellies are signs of aging which men accept and which look well on them while women, on the other hand, will make everything possible to look younger since beauty, for most of them, is related to youth. For this, they will starve week after week to look slimmer; they will use any kind of cream that promises effective results and they will even undergo painful surgeries to change their appearance. What ‘s more, to l ook good women need more time than men. Choosing the perfect outfit, wearing a natural make-up, axing their whole bodies and doing their hair takes a lot of effort and preparation.Men only need to grab any clean shirt at hand, shave and wear a nice perfume and they are ready to go out. But the most important advantage of being a man, as regards physical differences, is none of the ones mentioned up to this point. Men do not need a toilet when they feel the need to pass water; any bush, tree or corner is enough for them to do so. At any moment, they may relieve themselves in the road while traveling, In the street or at any place they feel like. For women It Is not so ass. Women need toilets. The main problem Is that. At public places. Staterooms are always full and do not usually have toilet paper or clean seat covers. Besides all this, men have more freedom than women. They do not usually take care of the children or change their schedules because one of them has a high temperature . They do not worry about their meals, homework or daily activities because they have a wife that does so. They just go out with their couples or friends having their minds in peace because someone else has taken care of everything before they left the house. In addition, they do not even need company to go to a bar to have a drink or to any other social event.It is very common to see men alone enjoying to be by themselves. In contrast, although women socialize more than men because they are more talkative and open to meet new people, they generally do not go out alone to relax or have fun. They try to plan a get-together with friends whenever their nannies are available to keep an eye on their children. Another reason for women to go out In groups Is that there Is an Implicit knowledge among our society that women alone In social events are not just enjoying the moment but looking for something else, for example men.Socially speaking, men have been benefited over women. Finally, mu ch has been said about women s and men's intelligence. Men have simple minds and use better thinking strategies. One clear example of this is that they have made women believe they are useless in chores related to the house. But it is not true that men cannot do the cleaning or the laundry In the same way women do. Fact, do things wrongly on purpose to avoid offering help again in the future. Moreover, they can only handle one task at a time.So while they lay the table, with a stroke of luck, a woman is cooking with the four hobs turned on with a boiling pot on each of them and at the same time watching a TV show and answering her children s demands. For men being â€Å"useless† ends being a benefit. Another point to take into account as regards men's and women's intelligence is that the first usually speak using short sentences to get to the point and avoid details. This has been proved to be a very effective technique in many fields, as for giving instructions, explaining o ne's ideas or scold the children.Women instead need the double of words to express the same and end being criticized or laugh at. To sum up, life would be much easier if I were a man. I would not have to work so hard every day to look beautiful, I would have plenty of free time to do whatever I like and I would not complicate my life trying to explain ideas that would never be understood. This may not sound well to the ears of feminists but men are still enjoying the benefits of their gender and they will keep doing so for many years to come.

Paper on oxycodone Research Example | Topics and Well Written Essays - 500 words

On oxycodone - Research Paper Example Oxycodone mechanism of action, entails stimulation of opioid-receptors inside an individual brain. Notably, it does not purge sensation of pain, but minimizes discomfort through increasing tolerance for pain. It also results in sedation plus respiratory depression (MedlinePlus, 2012). The key therapeutic intention of Oxycodone is to alleviate modest to relentless pain, and to enhance effectiveness of particular anesthesia drugs. It offers pain relief through binding to receptors located in spinal cord and brain, specifically the opiate receptors. Therefore, once the opiate receptors are blocked, it triggers discharge of dopamine from the brain (Portenoy & et al, 2007). Oxycodone is highly addictive, and can result in abuse plus dependency. Repeated use can result in the development of tolerance, and the prescribed dose will no longer be effective in creating intended results. Unintended use mostly involves managing respiratory depression, by trying to experience a sense of euphoria, in addition to to holding back withdrawal symptoms, and as such, many of its abusers turn to heroin (Roth & etal, 2000). Users seek its euphoric, but relentless withdrawal effects together with its sedative property, since its high opioid content makes it to be absorbed over an extensive period. They then become mentally and physically reliant on it. The sensation sought by users, especially those with chronic disruptive pulmonary ailments and respiratory depression, involves decreasing their respiratory impel, and this simply results in apnea. It also causes severe hypotension, since it compromises the capacity to maintain blood pressure, while producing orthostatic hypotension (Riley & et al, 2008). Thus, vasodilatation generated by Oxycodone further diminishes cardiac output along with blood pressure. Consequences of prolonged use include reduced levels of testosterone and enlargement of prostate. Other long term effects include

Questions about the NSA Research Paper Example | Topics and Well Written Essays - 2250 words

Questions about the NSA - Research Paper Example These include e-mailing and telephone addresses used in communication and the dates and times of the communications. However, the programs do not give permission to collection of the content of the e-mails or calls themselves (Electronic Frontier Foundation). It is worth noting that although a huge amount of the information is collected, a vast majority of it does not usually get reviewed. This is because of the unresponsive nature of the information toward the limited queries authorized for purposes of intelligence. These programs are also subjected to extensive regimes of internal checks, more so for U.S persons and are monitored by the FISA court together with the congress. Therefore, NSA bulk collection programs are important tools in fighting against terrorism, they are greatly helpful in identification of terrorist plots aiming the homeland. The tools have the uniqueness of producing intelligence that is otherwise not available to the NSA. During the time before the 9/11 terrorist attack in New York, the NSA failed to establish that a call made by one of the persons involved in the attack, one al-Mihdhar, was in fact originating from San Diego, California. Instead, despite intercepting and transcribing the calls, NSA could not get to know al-Mihdhar’s calling location, leading to the conclusion that he was overseas. It is because of this that programs were developed to close such gaps that allow individuals like al-Mihdhar to go undetected while communicating, in fact while in the United States, during plotting of terror attacks. One such program operates under the FISA Court authority and which is pursuant to FISA’s â€Å"business records† authority, which has a common reference as â€Å"Section 215†. Together with similar programs in operation pursuant to FISA, and including exercising of trap/pen authorities,
