Nobel Prize Winner James Watson Free Essays

Among the most outstanding and disputable Nobel Prize beneficiaries is James Watson. He, along with Francis Crick and Maurice Wilkins, was granted the Nobel Prize in the year 1962 in the Physiology or Medicine class. He is one of the researchers who found the sub-atomic structure of the DNA which is hailed as one of the extraordinary forward leaps in the field of Sciences. We will compose a custom exposition test on Nobel Prize Winner: James Watson or then again any comparable point just for you Request Now James Dewey Watson was conceived on April 6, 1928 in Chicago, Illinois. In his initial life, he was supposed to be partial to fowl looking along with his dad. At the point when he was 12 years of age, he was a piece of the acclaimed radio show entitled Quiz Kids, a game which provoked youthful understudies to a test challenge. At 15 years old, Watson entered the University of Chicago with the assistance of the then liberal arrangement of Robert Hutchins, the University president. In 1946, his enthusiasm for the field of science transformed from his previous worry on ornithology to hereditary qualities after he had perused What Is Life? by Erwin Schrodinger. In 1947, he got his Bachelor’s qualification in Zoology from a similar college. Among Watson’s first impacts was Salvador Luria, additionally a Nobel Prize victor. He was fascinated to the latter’s work which uncovered him on the idea of hereditary changes. In the primary long stretches of 1948, Watson began to seek after his Ph.D. research at Indiana University at Luria’s lab. He had the option to meet with another Nobel Prize beneficiary Max Delbruck. Delbruck and Luria were the pioneers of the Phage Group, a development of geneticists who experienced examinations and explores on microbial hereditary qualities. In the end, Watson was likewise ready to work with the gathering as a working researcher. His involvement in the Phage bunch opened up his logical information on the nature and structure of qualities. So as to build up his insight about the segments of a quality, he took a course with another researcher Feliz Haurowitz in 1949 in which he had the option to pick up the customary perspectives on qualities, for example, qualities were proteins and the other way around; that qualities have the ability to recreate themselves; and other logical information about the DNA. In any case, through with each one of those information, Watson was likewise intrigued with crafted by Oswald Avery clarifying that DNA was to be sure the hereditary particle. Towards his doctoral examinations, he experienced X-beams explores which endeavored to de-inspire bacterial infections. In 1950, he got his Ph.D. in Zoology at Indiana University. To have the option to improve more his insight on hereditary qualities and hereditary arrangement, Watson went to Europe to seek after a postdoctoral report. He remained at the research facility in Copenhagen claimed by a natural chemist named Herman Kalckar whose reviews were likewise connected with the nucleic acids. Through his stay with Kalckar’s research center, he had the option to lead explores different avenues regarding another individual from the Phage gathering, Ole Maaloe. The latter’s studies and explores were worried on the DNA and the previous speculation that it is the hereditary atom. In a gathering in Italy where he went with Kalckar, he met Maurice Wilkins who was likewise a given geneticist. In an occasion, Wilkins had demonstrated Watson a X-beam diffraction information for DNA (which was initially turned out to be by Rosalind Franklin). In the wake of seeing the X-beam, he reached a determination that DNA had an unmistakable structure. Watson endeavored to find this through his trial research done in various colleges. Watson went to a choice to be acquainted with performing X-beam diffraction tests for the explanation that such endeavor would lead him to a progressively likely and simpler disclosure of the DNA structure (He was motivated by Linus Pauling who had the option to distribute the protein alpha helix model with his unremitting endeavors in experiencing X-beam probes atomic model. In 1951, Watson, along with Francis Crick and Maurice Wilkins, began to work out a progression of exploratory investigates utilizing Franklin’s X-beam discoveries on DNA structure. A discussion was said to happen during the time of test explores among Watson, Crick and Wilkins for the explanation that they were utilizing Franklin’s information and discoveries without the latter’s information and assent. To additionally contemplate Franklin’s X-beam discoveries, Watson went to one of Franklin’s course by which she clarified how she got her discoveries on the DNA structure. Initially, Franklin guaranteed that the DNA was organized in helix-structure. With this, Watson had begun again to build a sub-atomic model however at long last it was condemn by Franklin by saying that the phosphate spines must not be in within yet outwardly. Anxious to complete their endeavor, the two utilized Franklin’s perceptions in their definitive endeavor to show up at the DNA structure model. Notwithstanding, 1951, the supreme subtleties of the synthetic structure of the foundation of the DNA were recognized by Alexander Todd, an organic chemist. With that, Watson and Crick were approached to quit working with the DNA structure in 1952. However the two had never totally set aside their longing to think of the DNA structure model. After various outings which uncovered Watson and Crick to various techniques and test frameworks that could help them in their record on DNA structure model, they were again approached to keep dealing with the DNA basic model by the then research facility executive Maurice Wilkins. As the years progressed, Franklin’s discoveries advances and even developed.â The two, once more, utilized Franklin’s discoveries in their trial research on the DNA structure. The most remarkable commitment of Watson in the whole quest for the basic model of the DNA was his disclosure of the nucleotide base sets. These base sets are supposed to be the central answer in fathoming the structure and capacity of the DNA. Watson utilized the Pauling custom, which he was in the past uncovered. On February 1953, Watson worked out an atom model which utilized a straight outskirts, and exacto cutting edge, white cardboard and glue. He made the particles level in their circle with the goal that he could slide the cardboard models and review how they work. Through such ad libbed models, Watson saw that the greater two ring (An and G nucleobase; additionally alluded as the purines) could be coordinated with a lesser one ring (T and C nucleobases; likewise alluded as the pyrimidines). Watson estimated if the tow sets could be combined through a hydrogen bond which he found conceivable. He at that point saw that the two sets could be put over on one another with the same general arrangement. To expound, the hexagonal rings were focal and the near courses of the five-part rings of An and G were the identical.â Watson seen that various individuals were becoming alright with the end goal that he viewed it as the appropriate response. He was directly for planning such end. Watson’s disclosure of the base sets was unswerving with what Chargaff, additionally a natural chemist, had just worked out. Not all that long that Watson and Crick had finished their trial research on the auxiliary model of DNA by closing the twofold helix type of the DNA. They introduced their discoveries through a diary entitled Nature. With this extraordinary disclosure, Watson and his co-researchers Crick and Wilkins were given the Nobel Prize in 1962 for their revelation of the structure of nucleic acids. All things considered, as referenced prior the discussion including the first works of Franklin had put the three Nobel Prize Awardees in so much reactions principally with their inability to recognize the commitment of Franklin. Be that as it may, Watson took the boldness to explain the issue and evaluate Franklin’s contribution in the revelation of the DNA basic model. In 1968, he distributed a book entitled The Double-Helix which clarified his team’s side in regards to the discussion with Franklin. He explained that it was not purposeful to sidestep Franklin all through their accomplishments. He said that Franklin was extremely one of the people who gave him the driving force to endeavor more diligently and make him progressively cautious in examining his test research on DNA structure.â In the end, his group included Franklin as one of the most significant people behind the accomplishment of their basic model of DNA. Watson’s distributed book caused people in general to acknowledge how researchers like him experience such a great amount of difficulties for logical disclosures which can truly help the whole humankind in elevating the nature of their lives. He had demonstrated that with extraordinary exertion and remarkable penance, anybody could triumphantly accomplish their objectives. Watson didn't stop his logical undertakings with his Nobel Prize honor. He worked with the Genome Project in 1988 which he held up until 1992. References: Hamilton, J. (2004).

Learning Disabilities Essay -- Disabilities Education Mental Health Es

Learning Disabilities This semester we have invested most of our energy finding out about and examining how we can best help remarkable understudies. A large number of these understudies are people with learning dissabilities. Despite the fact that it would be hard for each educator to comprehend the differentiations, side effects, shortcomings and qualities of each inability, it very well may be exceptionally useful to have a general information on the inabilities that may upset an understudies capacity to learn. Dissimilar to different inabilities like loss of motion and visual impairment, a learning incapacity (LD) is a concealed impediment. A learning handicap doesn't distort or leave noticeable signs that would welcome others to be understanding or on the other hand offer help (Council for Exceptional Children (CEC),1999). Along these lines as instructors it will be our duty to give that understanding and support for those kids previously analyzed and furthermore be aware of the notice signs that might be side effects of a formerly undetected handicap. The National Institute of Mental Health (NIMH) (NIMH, 1999) portrays learning incapacities as follows: LD is a confusion that impacts people groups capacity to either decipher what they see and hear or to interface data from various pieces of the mind. These constraints can appear from numerous points of view. As explicit troubles with communicated in and composed language, coordination, restraint, or on the other hand consideration.

Learning inability can be long lasting conditions that, sometimes, influence numerous pieces of a people life: school or work, day by day schedules, family life, and once in a while even kinships. In certain individuals, many covering learning inabilities might be evident. Others may have a solitary disconnected learning issue that has little effect on different regions of their lives (National Center for Learning Disabilities (NCLD), 1999). It is imperative to recall that the term learning inability doesn't have any significant bearing to understudies who have learning issues that are essentially the aftereffect of visual or then again hearing issues, mental impediment, enthusiastic issues, or distraught because of their condition, culture or monetary foundation (US Division of Education (USDE), 1999).

What Exactly Does PTSD Do to the Brain

What Exactly Does PTSD Do to the Brain PTSD Causes Print How Trauma and PTSD Impact the Brain By Erin Maynard facebook Erin Maynard is a writer, president of PTSD Survivors of America, and a passionate advocate for people living with PTSD. Learn about our editorial policy Erin Maynard Medically reviewed by Medically reviewed by Carly Snyder, MD on February 13, 2020 facebook twitter linkedin Carly Snyder, MD is a reproductive and perinatal psychiatrist who combines traditional psychiatry with integrative medicine-based treatments.   Learn about our Medical Review Board Carly Snyder, MD on February 13, 2020 Post-Traumatic Stress Disorder Overview Symptoms & Diagnosis Causes & Risk Factors Treatment Living With In Children Martin Dimitrov / Getty Images Trauma can impact people in a variety of ways and can even have a lasting impact on the brain. In some cases, it can lead to post-traumatic stress disorder (PTSD), a trauma- and stressor-related disorder that results in improper processing and storage of traumatic memories. Because of the way these memories are stored, people with PTSD exhibit symptoms such as recurrent memories regarding the event; traumatic nightmares; dissociative flashbacks; hypervigilance; engaging in risk-taking behavior; and an exaggerated startle response.?? Not all people with PTSD experience the same symptoms or have the exact same pattern of brain changes. However, researchers have been able to use neuroimaging techniques to look at some of the different areas of the brain that play a role in the development of the condition. The National Institute of Mental Health reports that an estimated 3.6% of U.S. adults had PTSD in the past year. Approximately 6.8% of all adults will experience this condition at some point in their lives.?? Parts of the Brain Impacted by PTSD Certain structures of the brain are closely related to some of the symptoms of PTSD. These structures include the amygdala and hippocampus (which are part of the limbic system); several parts of the prefrontal cortex (PFC)??; the mid-anterior cingulate cortex and the right inferior frontal gyrus. PTSD causes the hyper-activation of some brain structures while other areas become hypoactive. Both the amygdala and the mid-anterior cingulate cortex become over-stimulated when a person has PTSD. However, the hippocampus, right inferior frontal gyrus, ventromedial PFC, dorsolateral PFC, and orbitofrontal cortex all become hypoactive, some to the point of atrophy. The Amygdala The amygdala is a small, almond-shaped region of the brain that plays a role in several functions, including: Some mating functionsThe assessment of threat-related stimuli (i.e., assessing what in the environment is considered a danger)The formation and storage of emotional memoriesFear conditioningMemory consolidation The Prefrontal Cortex (PFC) The prefrontal cortex (PFC) is an area of the brain found in the frontal lobe. This region of the brain plays an important part in PTSD. Some of the key functions of the prefrontal cortex include: Emotional regulationInitiating voluntary, conscious behaviorsRegulating attentionDecision-makingInterpreting emotions The ventromedial PFC helps suppress negative emotions, as well as playing a role in personal and social decision-making. It also plays a major role in the latter part of memory consolidation, as well as regulating extinctionâ€"the weakening and eventual dissipation of a conditioned response. The dorsolateral PFC modulates decision making and working memory. Working memory actively holds transitory information before it becomes part of the long-term memory during memory consolidation. The orbitofrontal cortex, one of the least understood parts of the brain, seems to be involved in sensory integration and signaling expected rewards and/or punishments in a given situation. It also modulates emotion and decision making. As a whole, the prefrontal cortex is interconnected to many brain functions, including memory consolidation and regulating slow-wave sleep (non-REM sleep, referred to as deep sleep).?? The Mid-Anterior Cingulate Cortex The primary function of the mid-anterior cingulate cortex (ACC) is to monitor conflict. The ACC also plays a role in: Emotional awareness (particularly empathy)Registering physical painRegulating autonomic functions like heart rate and blood pressure Research has found that decreases in cortical thickness in the ACC are linked to increased PTSD symptoms.?? The Hippocampus The hippocampus helps regulate smell, spatial coding, and memory. More specifically, the hippocampus helps store long-term memories, basically helping to decide what goes from being a short-term memory to what becomes a long-term memory. This process of turning short-term memory into long-term memory is what is referred to as memory consolidation. Damage to the hippocampus can also release excess cortisol (a stress hormone).?? The Right Inferior Frontal Gyrus The right inferior frontal gyrus is involved in modulating risk aversion. Studies show that transcranial magnetic stimulation (TMS) of this brain region may  reduce some risk-taking behavior.?? The Brains Response to Trauma When your brain identifies some type of threat, the amygdala is responsible for initiating a fast, automatic reaction known as the fight-or-flight response. Think of the amygdala as the alarm that sounds when something poses a danger. This alarm prepares your body to respond, either by dealing with or getting away from the threat.   The amygdala also communicates with other areas of the brain, including the hypothalamus, which then releases the stress hormone cortisol. It is the brains prefrontal cortex that must then assess the source of the threat and determine if the body needs to stay on high alert to deal with the threat or if the brain needs to begin calming down the body. The prefrontal cortex acts as a braking system that helps return your body to a normal state when you realize that the threat doesnt pose a danger or after the threat has passed. When people have symptoms of post-traumatic stress disorder, the amygdala becomes hyperactive while the medial prefrontal cortex becomes hypoactive. In other words, the part of the brain that triggers a fight-or-flight response responds too strongly, often in a way that is disproportionate to the danger posed by the threat. At the same time, the part of the brain responsible for calming this reaction does not work well enough. How the Fight-or-Flight Response Works The Consequences of Trauma When examining the functions of the various structures of the brain, the correlation between a change in those structures’ activity levels and some PTSD symptoms becomes clearer. Hypervigilance The over-activity of the amygdala presents as symptoms of hypervigilance and the exaggerated startle response.?? Because the amygdala overreacts, norepinephrine is released but then not adequately controlled or dealt with by the prefrontal cortex. As a result, people with PTSD experience symptoms of hypervigilance. They become overly aroused and are on high alert, which can make it hard to relax and to sleep. A person may feel that they are always tense and even small triggers can lead to react as if they are facing or re-experiencing their original trauma. Distorted Recall The hippocampus is involved in explicit memory processes and in the encoding of context during fear conditioning. When the hippocampus fails to function optimally, it impacts the way a person remembers and recalls memories, especially memories that contain a fear elementâ€"such as those related to trauma.?? In terms of PTSD symptoms, this results in: Recurrent memories regarding the eventDistorted negative beliefsDissociative flashbacks Impulsive Behavior Changes to the right inferior frontal gyrus help to explain why people with PTSD may suddenly engage in high-risk activities. Research has found that reduced cortical thickness in certain areas of the brain associated with emotional regulation and response inhibition, including the right frontal gyrus, is linked to impulse control problems in PTSD.?? A Word From Verywell When thoroughly examining the relationship between brain function and a persons symptoms, it becomes easier to understand many of the complex manifestations of PTSD. Although understanding the brain in this way may not provide direct symptomatic relief to someone living with PTSD,  it can be helpful in understanding why the symptoms are happening and, in turn, help the medical community continue to develop more effective interventions.

Hamlet Hero Or Villain - 2396 Words

Hamlet Essay: Hero or Villain? Distinguishing between a hero and a villain can be extremely difficult especially if one does both heroic and evil actions. A perfect example of someone that may confuse others of a fair or foul status is Marvel’s Deadpool. Deadpool is a very unique character in Marvel’s franchise as he is not necessarily categorized as a hero or villain, he is mainly seen as an anti-hero as he seeks out good deeds, but uses morally incorrect ways to accomplish them. The play Hamlet by William Shakespeare introduces us to a character named Hamlet, who is also the Prince of Denmark, is gone to by the apparition of his dad and told that his uncle Claudius, who is presently King, was in charge of his homicide. Hamlet is torn about attempting to retaliate for him, and winds up putting on a show to be crazy. He employs actors to do a play around a man who murders his sibling to wind up lord to see Claudius response. Hamlet affirms that Claudius was dependable, winds up being injurious to his mom Gertrude for shacking up with the killer of his dad, and murders his sweetheart Ophelia s father suspecting that it is Claudius. Ophelia goes crazy from having her sweetheart slaughter her father and bites the dust. Her sibling Laertes is angered and is persuaded by Claudius to execute Hamlet.

The paper therefore presents a summary of major (IT-based) innovations and an analytical framework with which to Structure an historical review Of how Information Technology innovations were adopted in the financial services sector and their impact. The early history of Information technology globally First wave From as early as 1846 the financial sector has been using Information Technology (IT), the history traces back to financial markets when the eelgrass was used to reduced stock price differentials between New York and regional stock markets. We will write a custom essay sample on IT project for Banking and Finance or any similar topic only for you Order Now Information technology was later employed in 1866 with the transatlantic cable equally enabled greater integration of securities trading in New York and London (B;tic-Lazy, Wood 2002). Further integration took place as the completion Of the transatlantic cable reduced the time delay to execute a trade in New York, which had been initiated in London from six weeks to only one day. These early innovations were accompanied by statistically significant evidence that the introduction of primitive forms of telecommunication substantially educing or even eliminated foreign exchange and security price differentials between geographically distinct markets, (B;tic-Lazy, Wood 2002). Hence at that time information technology’ reduced interest rate risk and operational risk for the institutions. In addition greater use of telegraph or telephone facilities also resulted in price related information becoming homogeneous by linking the head office with branches in different domestic and international locations or by providing dealers and banks with the same price information in a timely manner. Second wave A second wave of Information Technology innovation in retail finance began n the late asses with the introduction of computers. This introduction allowed institutions to keep up with growth in business volume while, at the same time, solve very specific problems and automate existing practices of specific departments. This resulted in the branch network quickly turning into the main point of contact with retail customers. A process-directed automation thrust dominated the specific application period and aimed at undercutting the cost of administrative tasks such as the labor-intensive cheese clearing systems. Computer applications were therefore concentrated n back-office operations (Morris, 1986), this was because it was felt that controlling a growing mountain of paperwork provided the potential for economies of scale at that time. As the benefits previously mention became apparent the incentive to automate at the individual branch bank level and to improve market-wide processes became greater. Technology further helped developed banks and took on the challenge of reducing cost and expanding their level of customer service and efficiency. In 1967 Barclay Bank (ELK) introduced the first Automated Teller Machine (ATM) in the world (Barclay, 1982) while IBM introduced the magnetic stripe plastic cards in 1969. These two innovations marked the birth of electronic banking. The chart of Figure IA on the following page shows this information. Use of Technology in the Organization, 1845-1995 (Figure IA) Impact on the Provision of Retail Finance Early Adoption Specific Application Emergence (1846-1945) (1945-1968) (1968-1980) Innovation in Reduction in Conversion from Growth of cross Service Offering inter-market price bank relationships.

(Sources: Morris (1986) and Squint;s (1991)) In a nutshell, technological changes have spread throughout many internal aspects of the banking organization. During this period the convergence of telecommunications and computer power resulted in true Information Technology applications as the emphasis of technological innovations shifted from data processing to communications. The Evolution stage Electronic banking is an umbrella term for the process by which a customer may perform banking transactions electronically without visiting a brick-and- mortar institution. This form of banking became popular in the early ass it was facilitated by banks mailing their customers a floppy disk with software that the customer could install onto their PC and accessing their accounts from the privacy of their homes. ( Canasta Research on 07/02/2013). Initially this service was for a fee. Then in the mid ass a big leap occurred with banks setting up websites for consumers to access both product and contact information. Within a few years after internet banking functionality was launched, this made the process of doing your banking online easy and accessible to everyone. This form Of banking has emerged as an option to customers and was offered by Caribbean banks as well. The major benefit according to one survey is an estimated cost providing that the routine business of a full service branch in the USA is $1. 7 per transaction, as compared to 54 cents for telephone banking, 27 cents for ATM (Automatic Teller Machine) banking and 1. 5 cents for Internet banking (Nathan 1999; Pun et al. , 2002). However it is unclear whether cost savings ill be the primary benefit derived from the adoption of e-banking systems, as any cost reductions achieved may not be a source of sustained competitive advantage for individual commercial banks. Cost savings using e-banking techniques are generally easily replicated by competitors. Secondly, cost savings are also accompanied by reduced entry barriers or increased market transparency leading to a further intensification of competition, ( Belgrade, Paris and ward, 2005 Key technological changes in retail finance Year Name Characteristics Contribution 1979-1985 Telephone Branches retail Multi-channel distribution system Banking UK, US intermediaries for banks base on an integrated customer account and information system ( Figure B) 1988-1996 Monde Cards (I-j) Debit card with re-writable Facilitate small value retail transactions micro chip with the potential to substitute central bank issued notes and coins 1989-1998 Digit cash (ML) Electronic only medium of Payment system and products that depend exchange and unit of account exclusively on only high-speed communication done through computers 1995-2001 Security First First intermediary working Technologies open new opportunities for Network Bank (US) through the internet. Ink growth and offer managers of banks possibilities to achieve high organizational flexibility Source (B;tic-Lazy, Wood 2002) The Barbados Experience Improvements In Barbados all banking institutions and major credit unions offer the most basic forms of e-banking. There is a well connected network of automatic teller machines (Atoms), telephone banking, debit cards, and electronic funds transfers (OFT). The majority of the ATM use in Barbados came about as a cost savings measure. Consequently, ATM banking has become the most popular form of electronic banking in Barbados, with even some non-bank entities costing similar services. However, the graduation to the next level of e- banking, Internet banking has been sluggish. According to ( Belgrade, Paris and Ward, 2005 ) the lack of advancement is for a number of reasons, one most obvious is a divide between customers who wish to use the technology and those who simply prefer traditional banking methods. However the increase in efficient by Automated Teller Machines can been seen in the graph below figure B Observation of Traditional and ATM banking: A Busy Day (No. F Customers per 30 Minute Intervals) Bank I 8 36 ATM I 10 90 15 Source: pa iris (2001 ) Traditional (Teller) A 5 c Within the back office operations of the institutions they have been major improvements across the banking sector, with the use (ARTS) Real Time Gross Settlement and, (ACH) Automatic Clearing House with increase capacity to process transactions. With regards to information systems Finance Core banking system is one of the information systems use as a customer management information syste m. The use of this system has allowed institutions to capture customer information which can then be used for the modeling of products to specific target markets base on the habits of the institutions clientele and overall profile. In accordance with the know-your- customer guild lines some Transactions Processing Systems such as Finance are even able to go a step further and record personal life events such as weddings, anniversaries and future plans of younger children and other personal information. Which all assist in the construction of products and services that will meet customer’s needs at every stage of their life. Hence the (T AS) is used as a strategic management information system in some institutions. In addition to cost savings and increase capacity (IT) has brought about payment innovations such as Sure-pay in Barbados. Sure-pay is a payment undying service that allows customers to pay an array of their bills in one location. The company Sure-Pay began its service just offering basic utility payments, and eventually evolve into a well recognize efficient entity which at one time even offered a payment service for tickets for former airline Red Jet and has now expanded to Trinidad Tobago. Risk The issue of capital flight and money laundering are real concerns that will surface with Internet-Banking, also the ability and cost of regulating this form of banking. This is especially so in an small open economy with a fixed exchange rate such as Barbados. For example if capital is allowed to leave at an rapid unregulated rate this could place pressure on the central bank’s reserves which can have a negative effect on the exchange rate and cause the parity of the dollar to be threatened, especially in cases where settlement of the transaction will be require in foreign currency. With respect to money laundering if we look at Internet-Banking it is unique because it offers the user anonymity, rapid transactions speed and wide geographic availability. For those reasons the issue of depositing and withdrawing money in and out of the system is extremely important because t is easy for layering to occur. Encryption technology, fire walls and the use of digital signatures are extremely vital verification tools and should be standard operating procedure with this evolving technology. An added defense in breaches or affiliated criminal activities is that banks should adhere to the commonly cited know-your-customer guidelines. If properly implemented, within an effective operational and regulatory framework, such guidelines should prove pivotal in preventing these kinds of crimes. Future expectations The future of Information Technology and the financial service industry will only be limited by the imagination of those who use the technology, or the regulators who need to keep abreast of how new technologies will permit circumvention of the law.
