BUSINESS LAW II - Essay Example In other words, if any financial institution fails, not the customers and taxpayers will bear the cost of such failed financial institutions but Wall Street. Additionally, bad debts will be dropped since banks among other financial institutions will be restrained from incurring unforeseen financial risks. This means that nearly all borrowers will be evaluated thoroughly to minimize obvious defaults. Notably, the Dodd-Frank Wall Street and Consumer Protection Act of 2010 works with the Consumer Financial Protection Bureau (CFPB) that ensures that financial institutions have high financial standards that they uphold at all time of their operations (Berson and Berson, 2012). It is also worth noting that the retained percentage will also minimize the losses incurred by financial institutions in case of defaulters. The Dodd-Frank Wall Street and Consumer Protection Act of 2010 and its components seems not to be favoring financial institution since it does not provide bail out for financial institutions during rough economy, rather, the government will shut down them down as they will be considered as failed

History of online Vidoe Games Essay Example | Topics and Well Written Essays - 2750 words

History of online Vidoe Games - Essay Example 1960s, extra computer games were developed for the public (frequently running on mainframe-computers), slowly rising in complexity and sophistication (Bellis, 2009) and (FreeBase, 2009). After this early games development period, video games deviated into diverse platforms and verities like: mainframe, arcade, personal computer, console and later handheld games. Online games  have been around for a while.   They started out years ago before the Internet on terminals, then over modems and now on the Web.   The explosion of online gaming is due to the growing amount of people who have access to the Internet.   Online games vary from basic text to 3d worlds that allow the ability to play other actual users who are connected to the game.   There are also many forums and social networking sites related to online gaming. In 1952, A.S. Douglas wrote his PhD degree at the University of Cambridge on Human-Computer interaction. Douglas created the first graphical computer game - a ve rsion of Tic-Tac-Toe. The game was programmed on an EDSAC vacuum-tube computer, which had a cathode ray tube display (Bellis, 2009) and (Celia Pearce, 2007). At its most basic level, an online game is the term used to represent games that are played over some form of computer network (in most cases, this means the Internet). One of the reasons for the expansion and growth of online gaming sites is the expansion of computer networks from small local networks to the Internet and beyond. Online games can come in a number of formats, ranging from simple text-based games to extremely complex games that include graphics and even virtual worlds. In regards to online gaming sites that allow you to win money, most sites require you to download their software. This is one of the distinguishing factors between TreasureOnNet.com and other similar gaming sites (Gupta, 2009). This era of video game history bears witness to the rise of the 32-bit, 64-bit, and 128-bit processor architecture in home console

Differences between the characteristics of a soft real time task

Differences between the characteristics of a soft real time task Ques 1:-Explain the key differences between the characteristics of a soft real time task such as web browsing and a non real time task such as e-mail delivery? ANS= Key Concepts Classification Of Real-Time Systems Real-Time systems can be classified from different perspectives. The first two classifications, hard real-time versus soft real-time, and fail-safe versus fail-operational, depend on the characteristics of the application, i.e., on factors outside the computer system. The second three classifications, guaranteed-timeliness versus best-effort, resource-adequate versus resource-inadequate, and event-triggered versus time-triggered, depend on the design and implementation, i.e., on factors inside the computer system. However this paper focuses on the differences between hard and soft real-time classification. Hard Real-Time versus Soft Real-Time The response time requirements of hard real-time systems are in the order of milliseconds or less and can result in a catastrophe if not met. In contrast, the response time requirements of soft real-time systems are higher and not very stringent. In a hard real-time system, the peak-load performance must be predictable and should not violate the predefined deadlines. In a soft real-time system, a degraded operation in a rarely occurring peak load can be tolerated. A hard real-time system must remain synchronous with the state of the environment in all cases. On the otherhand soft real-time systems will slow down their response time if the load is very high. Hard real-time systems are often safety critical. Hard real-time systems have small data files and real-time databases. Temporal accuracy is often the concern here. Soft real-time systems for example, on-line reservation systems have larger databases and require long-term integrity of real-time systems. If an error occurs in a sof t real-time system, the computation is rolled back to a previously established checkpoint to initiate a recovery action. In hard real-time systems, roll-back/recovery is of limited use. Ques2:-Name any two important sensors devices and two actuator devices use in real time applications and explain the physical principals behind their working? ANS= one actuator is robotic arms that is mainly used in the manufacture company of any car and bike..the robotic adjust the parts of car inside the cabenet†¦ Input=tempreture ,,,pressure,light,etc its all the input of for the actuator†¦ Output=electrical signal Ques3:-:- In a hard real time system, is it necessary that every task in the system be of hard real time type? Explain your answer using a suitable example? Ans:-Contain only tasks with no hard timing constraints.Also known as â€Å"best effort† systemsMost modern operating systems can serve as the base for a soft real time systems.Examples:multimedia transmission and reception, networking, telecom (cellular) networks,web sites and services, computer games. Contains tasks with hard timing constraints.Requires formal verification/guarantees of being to always meet its hard deadlines (except for fatal errors). Examples:air traffic control , vehicle subsystems control, medical systems There are two different execution models: In a preemptive model of execution a task may be interrupted (preempted) during its execution and another task run in its place. In a non-preemptive model of execution after a task that starts executing no other task may execute until this task concludes or yields the CPU. The task model for a real time system has two main types: Ques4:-What are the different types of timing constraints that occur in a system? Give examples of each. Time constraints of data:-The controlling system interacts with its environment based on the data available about the environment, say from various sensors e.g position , velocity, and altitude, sensors and cameras. It is known that the state of the environment, as perceived by the controlling system, be consistent with the actual state of the environment. The second data is processed further to derive new data, for example data such as aircraft position, heading velocity are used to derive the time at which it would touch ground if allowed to land. Time constraints of actions:- having covered the timing aspects of events and data we are now in a position to summarize the reasons for actions being associated with time constraints. Time constraints dictate the behaviour of the environment they constrain the rates and time at which input arrive at the system for example in an air traffic control system, a flight commander must not ask for permission to land until the aircraft is 10 minutes from the airport. Behavioral constraints ensure that the environment of a system is well behaved, whereas performance constraints ensure that the computer system performs satisfactorily. Each of performance and behavioral constraints can further be classified into the following three types: Delay Constraint Deadline Constraint Duration Constraint These three classes of constraints are explained in the subsequent sections. Ques5:-Explain why safety and reliability are not independent issues in safety-critical hard real time systems. Explain the basic techniques you would adopt to develop a software product that is required to be highly reliable Ans:- it will crash, and it wastes lot of time and money to create a new system, and if the system is crash it will not work as a real time system ,it loses the reliability ,therefore it is necessary to hard real time systems that safety and reliability depends on each other, thus system works as a true hard real time system. In traditional systems ,safety and reliability are normally considered to be independent issues .it is therefore possible to identify a traditiona system that is safe and unreliable and systems that are reliable but unsafe.for ex- word processing software may not be a reliable but is safe, Software Reliability is an important to attribute of software quality, together with functionality, usability, performance, serviceability, capability, installability, maintainability, and documentation. Software Reliability is hard to achieve, because the complexity of software tends to be high. While any system with a high degree of complexity, including software, will be hard to reach a certain level of reliability, system developers tend to push complexity into the software layer, with the rapid growth of system size and ease of doing so by upgrading the software. For example, large next-generation aircraft will have over one million source lines of software on-board; next-generation air traffi c control systems will contain between one and two million lines; the upcoming international Space Station will have over two million lines on-board and over ten million lines of ground support software; several major life-critical defense systems will have over five million source lines of software. While the complexity of software is inversely related to software Ques6:-Give an example of soft real time task and non real time task. Explain the difference in between these two types of tasks? Ans:- A soft real-time system on the other hand will tolerate such lateness, and may respond with decreased service quality (e.g., omitting frames while displaying a video). Soft real-time systems are typically used where there is some issue of concurrent access and the need to keep a number of connected systems up to date with changing situations;a non real time tasks are batch processing jobs,e -mail,and background tasks such an event logers .you may ,however ,argue that even these tasks, in the strict sense of the term ,do have certain time bounds.an email is expected to reach its destination at least with in a coupleof hours of being sent.similar is the case with a batch processing job such a pay-slip printing what then reality is the difference between a non real task and a soft real time task for non real time tasks ,the associated time bounds are typically of the order of a few minutes hours or even days .in contrast the time bounds associated with soft real time tasks are at most of the order

Humans are Responsible for Global Warming Essay -- environment, global

This essay offers a defense to the position that humans are responsible for global warming. What is Carbon Dioxide? Before attempting to answer any questions based on observations about carbon dioxide, taking a moment to identify the carbon dioxide helps to ensure a clear understanding of the element. According to Princeton University (n.d.), â€Å"carbon dioxide, carbon dioxide, is a heavy odorless colorless gas formed during respiration and by the decomposition of organic substances†. This naturally occurring element is exists in the Earth’s atmosphere where it circulates between water, plants, soil and animals. Current Carbon Dioxide Levels Knowledge of carbon dioxide levels in the atmosphere helps scientists understand how the gas affects Earth, its atmosphere and any potential global warming. Carbon dioxide levels, measured in parts per million (ppm), defines a unit of measure â€Å"as a measure of small levels of pollutants in air, water, body fluids, etc. Parts per million is the mass ratio between the pollutant component and the solution† (TET, n.d.). Rising every year since 1958, the current atmospheric carbon dioxide level is 396.81 ppm according to co2now.org (2014). Scientists believe that they only have a short amount of time to get this and other greenhouse gases under control before the planet crosses the point of no return. With a level of 396.81 ppm of carbon dioxide in the atmosphere, one may wonder if this level is the highest level the Earth has seen in the last 450,000 years. According to the graph found at Planet Seed’s website (2014), this is the highest levels of carbon dioxide level recorded in that time. In fact, the graph clearly shows a spike in carbon dioxide levels in the last portion of the g... ...3). Overview of greenhouse gases.

When Hitler Stole Pink Rabbit Personal Reflection

The book, when Hitler Stole Pink Rabbit introduces a very intelligent, smart, and social girl Anna, who has a brother named Max, and lives with her mother and father. Her father has many connections to other people since he is a well known Jewish writer; therefore, he knew to move to Switzerland in case Hitler won the elections and took control. Anna does not know how lucky she is to be saved from all the trouble taking place in all of Germany.Going from country to country is hard for any family, and I know it would be hard for me, but Anna showed me that it does not matter what appends as long as we have our family together. When Anna warned her dad about almost being led to the train to Germany, it showed how bright she was. She adapted to the Switzerland lifestyle very quickly. She made many new friends and even the boys wanted to play with her. Instead of being homesick and complaining about wanting to go back, she taught me to make the best of difficult situations and find the p ositive in everything.A few months later she had to move to Paris, France. Moving constantly is something I would hate to do, especially on train, but she kept a positive attitude the whole way. She struggled to speak French and in school, and sometimes she could not do anything about it. Her difficult time are an example that nothing can always go the way you want It to. During the story, there was a problem where one of the beds ended up breaking, and they needed to hire someone to fix It. The person who they hired to fix the bed turned out to be anta- Jewish and rude.Her mother was extremely upset and kicked him out of the house. They decided to move away to England with an uncle. Her mom Is a strong example of letting the negative Influences go away and Instead being with better, positive Influences like family. Father worked hard in his writing Job and It reminds me of my parents and their hard work to support my family. Without the work they do, we would not be able to have wh at we have. Mother also relates to my mom, they both make sure we do well In school and stay focused.Without mother, Anna would not be motivated to continue to try and learn French. When Max and Anna fight, It reminds me of how I do not always get along with my siblings and sometimes we get Into arguments. In the end, the argument never matters. When Hitler Stole Pink Rabbit Is a great book that shows the world through the perspective of a ten year old girl. I related to Anna and her life struggles. Anna and her family stay together through the whole experience, and they find out a way to make their dangerous situation work.This story leads me to believe that everything happens for a reason, and whatever happens, have a positive look to It because everything happens for a reason.

Stroop Effect

Stroop Effect CogLab Report Stroop Effect CogLab Report The Stroop effect is a test that demonstrates a decrease in reaction time that occurs when the brain receives conflicting information. When sensory information conflicts, a processing delay occurs in the brain; this is interference. If a specific color is paired with its corresponding word then those two pieces of information are compatible. If the information conflicts then the individual is forced to make a decision.It is hypothesized that reaction times will be lower when the word and font color are the same and reaction times will increase when the word and font color are different. Method Participants A total of 20 undergraduate students participated in this experiment; 18 were women and 2 were men. Materials Students used CogLab, an online laboratory used as part of a cognitive psychology class, to complete the Stroop Effect task. Procedure Participants were asked to identify the color of each word as quickly as possible.T he reaction times were measured and analyzed to compare the difference between words and colors that match and words and colors that mismatch. Results A paired-samples t-test was used to analyze the data. When font color mismatched, participants had significantly longer reaction times (M = 881. 74, SD = 200. 90) than when font color matched (M = 774. 37, SD = 230. 23), t(19) = 4. 62, p < . 001. Discussion The results supported the initial hypothesis; in mismatched conditions reaction time increased.The Stroop effect is a selective attention task; it shows us about how our brains process information. When presented with conflicting stimuli, participants had to react to both sets and make a decision. Reading is an automatic process. The presence of the mismatched colors interfered with participants’ ability to react and properly identify the correct word. The Stroop effect shows us that automatic processes like reading, more strongly impact attention.

10 Critical Essay Topics on Police Brutality

10 Critical Essay Topics on Police Brutality If you are tasked with writing a critical essay on police brutality, you may be unsure of what facts would best substantiate your case. For this reason, and many more, you will find a list of helpful facts below which can be used to help you write your next piece: The vast majority of American police officers feel strongly that the use of force beyond that which is legal is not acceptable. Nonetheless cases of extreme abuse of authority do take place infrequently. Many departments will take tough stands against police abuse and at times, many fellow officers disregard this and use more force than is necessary when they make an arrest. On that note, the officers who witness this unnecessary use of force ignore the conduct. In order to mitigate the high rates of police brutality training and education must be integrated into the modern police force. First line supervisors in tandem with department chiefs play a critical role in the prevention of abuse among police officers. Policies which are community oriented have very little impact in reducing the abuse of authority among police officers. More importantly, black and non-black police officers hold very different views about the impact that race and socio-economic background has on the likelihood that police officers will abuse someone. The code of silence is among one of the worst culprits of continued police brutality. Officers face serious struggles reporting other officers. There is a big gap found between the attitudes that officers hold about reporting other unit members and the actions that they take. Even if officers do not believe that they should protect those who conduct themselves illegally, they will not often turn in officers whom they know have broken the law. Over 80% of police officers surveyed reported that they do not accept the idea of the â€Å"Code of Silence†, which refers to remaining quiet in the face of other officers engaging in misconduct, is necessary in order for police officers to maintain mutual levels of trust among one another. However, nearly one quarter of the same surveyed group agreed that whistle blowing on others is not worth the hassle that accompanies it and two thirds of that group reported that the officers who do report other officers for misconduct are given the c old shoulder. That same group reported that as a result, almost all officers will simply turn a blind eye. There is a significant gap between the thoughts held about reporting other officers and the actions taken by other officers such that 61% of officers surveyed stated that police officers rarely report serious criminal violations which involve another officer abusing their authority. There is a significant role played by the race, class, and demeanor of those involved. Citizens who are disrespectful or show hostility toward the officer increase their chances of being arrested. What’s more, research from the Police Foundation indicates that American police officers are evenly divided as to whether officers are more likely to arrest someone who shows what the officer in question believes to be a â€Å"bad attitude†. Half strongly disagree that showing a bad attitude increases the chances of being arrested while the other half feel that it strongly does. Some studies indicate that 17% of officers treat whites better than other minorities. An addition 11.1% of officers indicated that they believed more violence was shown toward blacks compared to whites. Another 14% stated that officers should use increased physical force against those who are poor compared to those who are middle class and in the exact same criminal situation. The responses indicate that white police officers believe that class and race are not important with regard to abuse of authority, but police officers who are black or another minority view the opposite. One study reviewed 1,565 cases and the results from that review indicates that reasonable force was used in 3.3% of cases with excessive force used in 1.8% of cases. This indicates that the use of excessive force constituted 35% of the daily encounters. This information was collected and reviewed in 1980 and since then the ability to garner the same level of insight into the frequency of excessive force has been significantly more challenges because of difficulties collecting such data and a lack of reports by other officers. Police forces have comparatively low psychological requirements to other federal or government branches where weapons are used. The lower psychological requirements and lower education levels results in increasing numbers of officers who regularly use excessive power. This, in tandem with the code of silence which often is enforced, results in the abusers being allowed to do as they please and not being stopped. In American the majority of officers do not approve of the use of excessive force. But a substantial minority do believe that using more than is necessary in a given situation is sometimes permissible. 30% of officers surveyed believed that police officers are not allowed to use the maximum amount of allowed force when they make arrests. Yet another 25% agreed that controlling someone who is assaulting an officer requires the use of more than what is the legal and allowable amount of force. In addition to this, 40% believe that using more force than necessary does not allow them to get their jobs done properly. The vast majority of surveyed police officers do not think that other officers use excessive force but 4.1% of officers regularly use more physical force than is necessary in a given situation. The issue here lies in the fact that the few who do are not reported by their fellow officers even if they witness it and this gives them a clean report. Having a clean report allows said officers to continue in their abuse of power and authority without the need to worry about being reported. Without the reports being filed, the individuals who oversee the fight against police brutality are unable to see a problem and therefore unable to fix it. Police brutality doesn’t stop to bother people because the stats of abusing the authoritative power are only growing. That’s why it’s necessary to write about this. As a result we also gathered sample topics on police brutality with a sample essay that will show you the idea of a proper paper. Moreover, you may use our tutorial on writing a critical essay. With all of this you’ll certainly know how to write a superb text. References: Bandes, Susan. Patterns Of Injustice: Police Brutality In The Courts.  SSRN Electronic Journal  n. pag. Web.

An Ethnic Experience Essays

An Ethnic Experience Essays An Ethnic Experience Essay An Ethnic Experience Essay For some people, Yelp is a way to see how well a new restaurant down the street is rated. For me, Yelp is a way of life. My curiosity, appreciation for technology and innate love for food have made me into somewhat of a foodie. Its one of my better qualities. But, it also left me slightly stumped when I eceived this assignment to eat at a restaurant whose culture I hadnt already experienced. After some serious brainstorming and a bit of in-class homework, I finally came upon an ethnic restaurant that had slipped through my fingers until then. Im glad it took me this long, because this assignment left me with a newfound love- Ethiopian Food. Of the details that really hang in my mind, one was definitely the mood of the restaurant. I went to Abyssinia Ethiopian Cuisine, a small unassuming place next to an ethnic market on a small street in Anaheim. I would ave missed it, had I not been looking for the address. We parked in the first stall next to the door and went in about half an hour before close. A wave of deliciously spiced air greeted me and my boyfriend as an older lady with an enormous smile walked us into the next room and offered any seat in the house. Every table had a simple tablecloth, a vase and a single flower. The walls were covered with paintings, prints and the occasional mirror. At the back of the room, there was a table about two feet tall curiously topped with eight small cups and accompanied by a stool. I could not make out if it was for children to sit at or an offering table similar to those in some Asian cultures. Music played softly and I could not help but notice the similarities to the little Indian music IVe heard, though this was certainly more soothing and relaxing. The lights were low and the ambiance was gentle, welcoming and ethnic at every turn. The menu was our next challenge once we found seats. I looked over the entirety of the options about 3 times before I admitted that I didnt even know how to pronounce the first entr? ©e. Every dish had an ethnic name and ibs sounded Just as crazy as inJera. My boyfriend recognized an appetizer being delivered to another table and the waitress helped us pinpoint it on the menu as sambusas. We ordered one filled with beef and another with lentils. A navigating explanation later, we learned that Ethiopian dishes are served large and communal- style and that we knew nothing about what we were diving into. So we took the waitresss advice, settled on Abyssinia Yebeg Tibs as our entr? ©e and hoped for the best. Our waitress, who may have also been the owner, soon brought our appetizers. They came as flaky triangles on a plate with a small bowl of some green condiment that was mildly spicy and reminiscent of guacamole. Two teeny spoons accompanied it, but they were rather inefficient in transferring enough to the sambusa and I quickly turned to dipping mine. Both sambusas were extremely savory, and you could still extremely flavorful, and it was my personal favorite. Our main entr? ©e came soon after and the presentation was very different from any food Id ever tried. We were brought a pizza pan about 15 inches across covered with inJera, a sour, spongy bread hat was extremely airy and bubbly on one side but flat, continuous and crepe-like on the other. The waitress spooned the lamb dish in the center and brought us a basket with more of the spongy bread. The lamb was cubed and stewed with Jalapenos, onion, garlic and tomato. It was very fatty in taste but well balanced because of the spice. The handful of sliced greens heaped on the bread helped cut the grease and added to the variety of textures on the table. The stew soaked through the inJera very quickly and I had to double or triple it to keep my hands clean. The Dessert onsisted of baklava, which is a very sweet pastry typical in Middle Eastern and North African culture. The pastry was flaky and filled with a layer of sweet nuts and syrup. It was the sharpest tasting baklava Ive ever had. I dont know if Ill ever come across a meal as curious as Ethiopian again, but I hope I do. It was a welcome deviation from the typical cuisine in the area. The culture is lovely and welcoming and the food is delicious. I definitely recommend the food for the adventurous, for the curious and for lovers of spice. Ethiopian is an experience in and of itself.

Bikers, Emo, Graffiti

Very often young people refuse to recognize the official culture. Instead, they become the supporters of the so called youth subculture. A youth subculture is a youth-based subculture with distinct styles, behaviors, and interests. Youth subcultures offer participants an identity outside of that ascribed by social institutions such as family, work, home and school. It is generally known that subculture is the culture of people, who are dissatisfied with their place in society. One of the first forms of protesting against the society of grown-ups was the HIPPIE movement.The hippie subculture was originally youth movement that began In the united states during the early asses and spread around the world. These people inherited the counterculture values of the Beat Generation, created their own communities, listened to psychedelic rock, embraced the sexual revolution, and used drugs such as marijuana and LSI to explore alternative states of consciousness. Hippies led a primitive life and the slogans of were Life is love and Children are the flower of life. Their idol was J.Tolkien, whose epic trilogy. The Lord of the Rings became the guidelines for Hippies. Hippies were not aggressive and wanted freedom. Hippie fashions and values had a major effect on culture, influencing popular music, television, film, literature, and the arts. One of the first forms of protesting against the society of grown-ups was the Hippies movement. The young Americans, protesting against the war In Vietnam, organized their communes. Another famous forms of subcultures are Bodybuilding, Memo, straight edger, Graffiti. Hip hopper.One of the newest subcultures is STRAIGHTEDGES. Roll;anally being a Straight edge meant that you didnt drink, smoke or take drugs. These days straight edger also participate in animal rights retests, follow a vegetarian diet and are involved In environmental and political issues and protest. Music also plays an important role. Straight edge bands originally grew out of the punk rock movement In the asses. Over the years straight edge popularity has increased, but attention has also been focused on the narrow- mindedness of some straight edger.Straight edge kids make a statement with their fashion as well as with their philosophy. A tidy appearance is popular, with baggy trousers and T-shirts. Tattoos are a popular statement of straight edge membership, s are pierced ear lobes with large holes. Bags taken from students at a high school In Utah contained chains and heavy chain necklaces. Perhaps it is the lack of any 1 OFF philosophy. Bodybuilding is a form of body modification involving intensive muscle hypertrophy; an individual who engages in this activity is referred to as a bodybuilder. In competitive bodybuilding, bodybuilders display their physiques to a panel of Judges, who assign points based on their appearance. The muscles are revealed through a combination of fat loss, oils, and tanning (or tanning lotions) Inch combined with lighting make the definition of the muscle group more distinct. Rhea most well-known for being a bodybuilder is Arnold Schwarzenegger. Memo is a style of rock music typically characterized by melodic musicianship and expressive, often confessional lyrics. Today memo is commonly tied to both music and fashion as Nell as the memo subculture.Usually among teens, the term memo is stereotyped with Nearing skinny Jeans, sometimes in bright colors, and tight t-shirts (usually short- sleeved) which often bear the names of memo bands. Bright colors, such as blue, pink, De, or bleached blond, are also typical as highlights in memo hairstyles. Memo has been associated with a stereotype that includes being particularly emotional, sensitive, shy, Introverted, or angst-ridden. It has also been associated with depression, self-injury, and suicide. The Goth subculture is a contemporary subculture found in many countries.It began in the United Kingdom during the early asses in the gothic rock scene, an offshoot of the post-punk genre. The Goth subculture has survived much longer than others of the same era, and has continued to diversify. The Goth picture has associated tastes in music, aesthetics, and fashion. Gothic music encompasses a number of different styles. Styles of dress within the subculture range from death rock, punk, androgynous, Victorian, some Renaissance and Medieval style attire, or combinations of the above, most often with black attire, makeup and hair.Graffiti (singular: graffito; the plural is used as a mass noun) is the name for images or lettering scratched, scrawled, painted or marked in any manner on property. Graffiti is any type of public markings that may appear in the forms of simple written words to elaborate wall paintings. In modern times, spray paint, normal paint and markers have become the most commonly used materials. Sometimes graffiti is employed to communicate social and political messages. To some, it is an art form worthy of display in galleries and exhibitions; to others it is merely vandalism.Hip hop as a cultural movement manifest in B-boning :breakfasting), graffiti writing, Digging and emceeing is an artistic commitment to seize freedom from oppressive social conditions. This artistic commitment inherent in hip hop culture expresses a reality of human transcendence which was originally born UT of the creative impulse and cultural improvisation of the oppressed African American, Afro-Caribbean and Latino American communities of New York City(with the South Bronx as the center) in the late asses.It was DC Africa Bumboat that outlined the five pillars of hip-hop culture: Mincing, Digging, breaking, graffiti writing, and knowledge.

Essay Example They were strong dogs tamed for freighting purposes. More so, these dogs have strong endurance and enthusiasm. Alaskan malamutes are friendly, devoted companion, loyal and affectionate that is jovial, playful yet dignified. Natural selection implies that the species that survive and reproduce are the ancestors to the next generation of the specie. Those animals that fails to reproduce, die and will not survive or continue to exist. Therefore, natural selection means nature selects which specie survive in the sense that if their adaptation to the environment helps them to survive since they are able to pass their genes to their offspring’s, but if they cannot fully adapt, they die and get extinct (Darwin 65-6). Scientists state that the first group of beetles appeared during Jurassic era. During this time, major groups of dinosaurs appeared too. Beetles are good adaptors to new environment by changing their lifestyle and feeding habits when acquiring new environment. Beetles managed to survive because they are herbivores. Because the environment cannot support unlimited growth of beetles, not beetles in the forest tend to survive and reproduce to their full capabilities. In this context, the green beetles tend to survive and reproduce because they camouflage and not easily seen by birds but the brown ones are easily seen and eaten by birds thus they reproduce less and hence wiped out. Protein synthesis is the production of protein molecules in accordance with DNA sequences. Protein synthesis takes place many as required. Contrary, DNA replication is the process of DNA copying itself. DNA replication takes place only once in cell generation during the S phase of the cell cycle (Baldi 70). After RNA has delivered the amino acids to increasing polypeptide chain, it leaves the ribosome, goes back to cytoplasm and takes another amino acid. As the ribosome

Anatomy of a Olympic Team Research Paper Example | Topics and Well Written Essays - 2500 words

Anatomy of a Olympic Team - Research Paper Example Unfortunately, the British Swimming Team turned up with only three medals, rather than the expected target of five to seven medals. This paper is all about researching and analyzing the various factors related to how the British Olympic Association’s systems and culture, the external influences on the team, individual athletes’ characteristics and the overall elements influencing the team, had an impact on the performance of the British Swimming team. From this analysis, one can discover how successful the British Swimming Team has been in achieving its targets, satisfying its swimmers’ needs, and preserving its team’s survival on an international level (Parliament UK 2010; Pullbuoy 2012; Swimpsych 2012). One of the first things related to this analysis that should be considered is the goal that the British Olympic Swimming Team was aiming to achieve; a target of five to seven medals for the 2012 Olympics. This goal was not an unrealistic one, as it was ba sed on various statistics. For instance, the number of finalists that had qualified for the Games was almost four times the number of finalists that had qualified back in the 2000 Olympics. Also, if the average number of medals won by the British Swimming Team in global swimming events in the last nine years is considered, the number comes up to approximately five. Furthermore, the number of swims was greater than it had been since 1992 and it is noted that 40% of the swimming team had swum faster in 2012 than in 2011. These statistics, along with the record of the highest number of swimmers in Britain’s Olympic history to qualify for the finals, prove that, in theory, a target of five to seven medals was certainly a realistic one. However, even though there were promising signs about the team completing the target, issues have been raised concerning the level of performance achieved. True, the statistics stated above are not the only factors that can control the team’ s performance. Nevertheless, the performance of individual swimmers can certainly be controlled; estimates were made using the best swimming times of individuals in relays from 2006, 2007 and 2012-2012. If, hypothetically, it is assumed that a swimmer can produce their best time in the heats, semis and finals, it was found that only 4 out of 49 swims produced personal best performances, while 8 out of 49 swims produced textile best times. This low quota of best times rightfully proves that the British Swimming Team was not sufficiently prepared, resulting in it facing a high level of difficulty. Had it been so, the results of the 2012 Olympics would have been greatly improved, as their targeted goal was an easily achievable one (Pullbuoy 2012). Another aspect that should be considered is the characteristics of key swimmers in the Great Britain Swimming Team. The team has a record breaker in their midst, in the form of Michael Jamieson, a first class Scottish swimmer. He won a silver medal at the 2012 Olympics after competing in the 200 meter breaststroke and has broken the British record at least 3 times. His skill set comprises mainly of the breast stroke technique and the butterfly technique. Jamieson’s coach, David McNully, speaks highly of him and is always on his toes to help Jamieson improve his technique. Jamieson has always been taking swimming seriously, always improving and very self-motivating. They might not have done so well in the 2012 Olympics, but with Michael Jamieson in

Estelle v. Gamble - Essay Example tates of America have been stained with cases of disparity and discriminatory malpractices while handling criminal cases, judgements and corrections respectively (Teitelbaum & Wilensky, 2009). The case of Estelle v. Gamble, however, hovered on top of the later substance, which indeed, marks the end of the procedure for dealing with crime. It is meant to implement correctional duties but not to inflict pain or act in an extra-judicial manned upon the prisoners. The inhumane behaviour that inflicted extreme medical torture and emotional suffering on Mr. Gamble while he was incarcerated could, therefore, finally cause an intense court case that ensured progressive alteration in the corrections departments of the United States of America. The hands-of-doctrine had concentrated thoughts on the correctional law in United States during the nineteenth century. The United States courts had regarded prisoners as â€Å"state’s slaves) and many judges believed that inmates had no rights given that they had been forfeited because of their crimes. Therefore, they did not interfere with the actions of correctional institutions since they believed that would constitute a violation of the principle of separation of power. In perspective, they did not want to intervene in the affairs of the authority of the executive branch that administer prisons. This is where the case of Estelle v. Gamble had created the greatest noticeable change, and they came to acknowledge that the courts had the right and duty to find resolutions over the constitutional claims of prisoners. The BOP (Federal Bureau of Prisons), had created a handbook in a bid to change the prisons system in a manner that would ensure healthy standards of living was created to be responsible for confining offenders in correction institutions that are humane, safe, secure and cost-efficient. As part of their duties, they are responsible for delivering necessary healthcare to prisoners in accordance with proper and reasonable

Health Care Essay Example | Topics and Well Written Essays - 1000 words

Health Care - Essay Example This places businesses who offer insurance coverage for their workers at a disadvantage as they spend more on health care. This also affects the households paying for their own coverage and has an impact on their spending on other goods and services. This paper gives a summary of the information on health care costs and the impact it has on society and the economy. The spending on health care has changed over the years and according to reports an average of $6,500 is spent on an individual annually. It is found that sixteen percent of the economy of the gross domestic product (GDP) which represents the total economic activity is devoted to health care. These findings are shocking and the major concern is the rapid increase over the years. Health spending grows faster than all other sectors in the economy for example education, transportation, education, transportation and agriculture that grow at the same rate as the economy. Health spending has been observed to exceed the economic growth over the years and the trends show significant differences between health care and all other sectors in the economy as explained by Shi and Singh (2009).These findings are staggering calling for major reforms in the health care sector since the impact on the economy is very significant. The country spends more on health care than all other developing countries and according to findings by the Organization for Economic Co-operation and Development. It was found that it spent 13 percent more than next highest spending country and this translates to 90 percent higher than their global competitors. Despite the relatively high spending, it does not maintain substantially better health care as compared to other developed countries. This may be because the wealthy countries can afford to spend more on health care and this is found to be a major correlation between health care and spending. Health studies show that the difference in health spending may be due to investment in

Four Basic Funtions of Management in Business Management Essay Example for Free

Four Basic Funtions of Management in Business Management Essay Every organization, regardless of size, has developed and implemented its own management concepts in order for it to run smoothly and accomplish the vision, goal, and objective, the company has set forth. The basic functions of management can be broken down into four different areas, allowing the organization to handle the strategic, tactical, and operational decisions (Sanjau, 2007). The four functions of management are essential to building strong teams and stronger organization. Common to all managers, the four functions are planning, organizing, leading, and controlling (Pakhare, 2007). A good manager is able to accomplish all four functions both effectively and efficiently (Bateman Snell, 2009). At Triumph, planning is the foundation in which all management decisions regarding the company will be based upon. The management teams will utilize the planning function to assess the status of the company today, as well as in the upcoming future. Once the management team has an agreed upon plan, and the company’s mission has been established, the team must determine how the desired results will be achieved. The next objective is to establish a goal and the strategies to achieve the goals set forth. After setting the goal the next step the management team will accomplish is to create a time line to complete the objective. The organizing function for the team at Triumph is to formulate the activities, which will include the accounting department, sales department and supply chain involved in helping reach the goal that has been set forth. Once all the different departments are set, it is up to the management team to departmentalize the process and create smaller groups to achieve the goals and objectives. Once the departments create their own teams a clear organizational structure is drawn and all employees are made aware of whom they are accountable too to help reach the goal of the company. Once the departmental teams are in place, the management team can help direct, communicate, motivate and assist the staff in meeting the company’s goals and objectives. At Triumph the management team will have open discussion with departmental teams to create and build positive working environment. In this process the employees feel as though they are part of the decision making and will ultimately help the company reach the desired goals and objectives. The final stage of the four functions of management is to control or establish the performance standard of the company’s objective (Bateman Snell, 2009). In this stage management keeps a close watch to make sure that all teams are on track to complete the goals and objectives that have been set forth and within the timeline. If at this point, it appears that one of the team’s seems to be off track then management will step in and help guide or make any necessary changes. The managers at Triumph know that ignoring any of the four functions can result in the failure of the company. Without using the planning stage first to make sure that all objectives are met and then organizing the plan and leading or motivating the team will result in not obtaining the objective or goal of the company. Managers at Triumph know that the final stage of creating an effective and productive team, one must control the budget, departments and cost efficiency of the work implemented to achieve the objectives. According to Barnes (2008), â€Å"if one can master the four management functions of planning, organizing, leading, and coordinating of resources, their opportunities are endless†

Accuracy of Rectal Water Contrast Transvaginal Ultrasound

Accuracy of Rectal Water Contrast Transvaginal Ultrasound Abstract Objectives:  To compare the accuracy of rectal water contrast transvaginal ultrasound (RWC-TVS) and double-contrast barium enema (DCBE) in assessing the presence and extent of bowel endometriosis. Methods:  This prospective study included 198 patients of reproductive age with suspicion of bowel endometriosis. RWC-TVS and DCBE were performed before operative laparoscopy by two groups of physicians specialized in endometriosis, each blinded to the results of the other groups. Findings of RWC-TVS and DCBE were compared with histological results. The severity of pain experienced during RWC-TVS and DCBE was measured by a 10 cm visual analog scale. Results:  In total, 110 of the 198 women had bowel endometriosis nodules confirmed at laparoscopy and histopathology patients. For the diagnosis of bowel endometriosis DCBE and RWC-TVS had a sensitivity of 96.4% and 88.2%, specificity of 100% and 97.3%, positive predictive value of 100% and 98.0%, negative predictive value of 98.0% and 88.0% and accuracy of 98.0% and 92.4% respectively. DCBE was associated with more intense pain than was RWC-TVS. Conclusions: RWC-TVS and DCBE have similar accuracy in the diagnosis of bowel endometriosis, but patients tolerate RWC-TVS better than they do DCBE. Keywords: double-contrast barium enema; rectal water contrast transvaginal ultrasound; bowel endometriosis; diagnosis Introduction Bowel endometriosis affects between 4-37% of patients with endometriosis1. Intestinal endometriosis lesions may have variable size2. Small endometriosis nodules located on the serosal surface of the bowel rarely cause symptoms and, therefore, do not require treatment2. Larger endometriosis nodules infiltrate the bowel wall and may cause various gastrointestinal complaints such as dyschezia, diarrhea, constipation, abdominal bloating and intestinal cramping1, 3. These symptoms may mimic irritable bowel syndrome. Symptoms caused by bowel endometriosis are nonspecific, often resulting in misdiagnosis or delay in diagnosis4. Physical examination may suggest the presence of rectovaginal endometriosis; however, it has poor accuracy in diagnosing rectosigmoid nodules5, 6. Until recently, the ultrasonic diagnosis of endometriosis was limited to patients with ovarian endometriomas and other imaging techniques were used for the assessment of bowel endometriosis including rectal endoscopic ultrasound, transvaginal ultrasound (TVS), double-contrast barium enema (DCBE), magnetic resonance imaging (MRI), multidetector computerized tomography enema (MDCT-e) and virtual colonoscopy7-10. TVS is a reliable non-invasive method to assess the presence and the extent of bowel endometriosis11. Injecting saline through a catheter into the rectum during TVS (rectal-water contrast TVS, RWC-TVS) may facilitate the identification of rectosigmoid nodules, the assessment of the depth of infiltration of endometriosis in the intestinal wall and estimation of the degree of stenosis of the bowel lumen. However, no previous study compared the accuracy of DCBE and RWC-TVS in the diagnosis of rectosigmoid endometriosis4, 12, 13. A preoperative diagnosis of the presence and extent of bowel endometriosis is necessary to determine whether surgery is required and to plan the surgical procedure with the colorectal surgeon14. Knowing before surgery the size and number of intestinal endometriosis nodules, the depth of infiltration of the nodules in the intestinal wall and the degree of stenosis of the bowel lumen allows determining whether surgery is required and may allow the surgeons to choose between nodulectomy and bowel segmental resection15, 16. In addition, determining before surgery the extent of bowel endometriosis allows the surgeon to inform the patient about the potential benefits and complications of the surgical procedure that will be performed. In fact, postoperative complications and evolution of digestive symptoms after surgery may differ between patients undergoing nodulectomy and those undergoing segmental resection, with a higher incidence of bladder-voiding dysfunction and postoperative constipation in patients undergoing the latter procedure. In this study, we compared the accuracy of DCBE and RWC-TVS in assessing the presence and extent of bowel endometriosis. Methods Study population This prospective study was performed between May 2012 and Aug 2016. Participants were recruited among patients of reproductive age scheduled for laparoscopy with strong suspicion of intestinal endometriosis based on symptoms and clinical examination. During this period, the imaging workup required that both DCBE and RWC-TVS were performed in patients with suspicion of bowel endometriosis. Institutional review board approval was obtained before initiating the study. Patients participating in the study signed a written consent form. Inclusion criteria for the study were: reproductive age and suspicion of deep pelvic endometriosis; presence of gastrointestinal symptoms that might be caused by bowel endometriosis; and desire to undergo complete surgical excision of the endometriosis. Patients were excluded from the study if they had previous bilateral ovariectomy; previous barium radiological examination or radiological diagnosis of bowel endometriosis; previous colorectal surgery; previ ous episodes suggestive of intolerance to iodinated contrast medium; renal or hepatic failure; refusal to undergo DCBE and psychiatric disorders. Symptoms were systematically investigated during the study period and they were recorded in a database. The presence of dysmenorrheal, deep dyspareunia, non-menstrual pelvic pain and dyschezia was investigated and the intensity of their symptoms was assessed in all patients on a 10 cm visual analog scale (VAS), on which the left extremity represented absence of pain and the right extremity indicated maximum intensity of pain. The presence of the following gastrointestinal symptoms was assessed: diarrhea-predominant irritable bowel syndrome; constipation-predominant irritable bowel syndrome; passage of mucus in the stools; rectal bleeding; intestinal cramping; and abdominal bloating. A symptom analogue scale questionnaire was used to estimate the severity of each gastrointestinal symptom. DCBE and RWC-TVS results were compared with surgical and pathologic findings. The radiologists performing DCBE and the gynecologists performing TVS were each blinded to the others results. They were blinded to the clinical data and knew only that the presence of intestinal endometriosis was suspected. All patients underwent laparoscopy within 1 month from the completion of the diagnostic investigations. Intestinal endometriosis was defined as the disease infiltrating at least the muscularis propria. Endometriosis foci located on the bowel serosa were considered peritoneal and not bowel endometriosis. The present study determined the accuracy of DCBE and RWC-TVS in assessing the presence of bowel endometriosis, estimating the size and the number of bowel endometriosis nodules and determining the presence of peritoneal endometriosis infiltrating only the intestinal serosa. Rectal water contrast transvaginal ultrasound technique Two physicians performed all the examinations according to a standardized procedure. RWC-TVS was performed by using a Voluson E6 machine connected to a transvaginal transducer. After the transducer had been introduced into the vagina, an assistant inserted a 6-mm flexible catheter through the anus into the rectal lumen up to a 15 cm distance from the anus. A gel infused with lidocaine was used to facilitate passage of the catheter. A 50 mL syringe was connected to the catheter and warm sterile saline solution was injected inside the rectum and the sigmoid under ultrasonic control. The amount of saline solution needed to show the rectosigmoid ranged between 100 and 350 mL, depending on the distensibility of the intestinal wall. One hundred milliliters of saline solution were continuously and slowly infused at the beginning of the procedure; the rest of the solution was infused when requested by the ultrasound. During ultrasound, when saline solution was not being infused, backflow through the catheter was prevented by placing a Klemmer forceps on the catheter. There w as no significant leakage of saline solution into the space between the catheter and the anus. Images were obtained before, during and after saline injection. Bowel endometriosis appears ultrasonographically as a nodular, solid, hypoechoic lesion, adjacent to and/or penetrating the intestinal wall. Hyperechoic foci may sometimes be present within the lesion. Intestinal distension allows defining the limits of the intestinal nodules and in particular the various layers of the rectal wall in order to estimate the depth of infiltration. The intestinal serosa is hyperechoic; the two layers of the muscularis propria appear as hypoechoic strips separated by a fine hyperechoic line; the submucosa is hyperechoic; the muscularis mucosa is hypoechoic and the interface between the lumen and the mucosal layer is hyperechoic. Rectal endometriosis infiltration is demonstrated by the fact that the hypoechoic nodule penetrates the intestinal wall and, in general, it thickens the muscularis mucosa. Two different ultrasonic signs are commonly used to describe this condition. Double-contrast barium enema All DCBE procedures were carried out using a motorized tilting table for fluoroscopic and radiological examination. In preparation, patients maintained a low-residue diet for 1 day prior to the examination in order to keep the enteric content fluid. The examination was performed after intramuscular administration of 20 mg (1 ampoule) Scopolamine in order to induce colonic hypotonia. The presence of bowel endometriosis was diagnosed on DCBE when the bowel lumen was narrowed at any level from the sigmoid to the anus in association with crenulation of the mucosa and/or speculation of contour. Tolerability of the examinations Immediately after each examination patients were asked to rate the discomfort encountered during DCBE and RWC-TVS by means of a 10 cm visual analogue scale (VAS), mild pain was defined as a VAS score of 5. Surgery and histological evaluation The surgeons examined the reports and the images of DCBE and RWC-TVS prior to laparoscopy. Although the diagnosis of recto-sigmoid endometriosis and its treatment were based on laparoscopic findings. All surgical procedures were performed laparoscope by a team of gynecological and colorectal surgeons with extensive experience in the treatment of pelvic and bowel endometriosis. In all cases, after adequate adhesiolysis, the sigmoid colon and rectum were systematically examined to verify the presence of endometriosis lesions. Bowel endometriosis lesions were removed by intestinal resection in cases of a single lesion >3 cm in diameter, a single lesion infiltrating at least 50% of the circumference of the intestinal wall or three or more lesions infiltrating the muscular layer. In all other cases of bowel endometriosis partial- or full-thickness disk resection was performed. Intestinal lesions infiltrating only the serosal layer of the bowel wall were excised by shaving. All visible les ions suspected to be endometriosis were excised and sent for histological examination in agreement with our clinical protocol. The surgical specimens were evaluated by histological; the depth of infiltration of the endometriosis nodules in the bowel wall was assessed. In cases of nodulectomy the specimens were macroscopically oriented along the intestinal wall (from the serosa towards the mucosa) and cut into macro sections of 2 mm thickness. From each macrosection tissue blocks of 1.5 cm length were obtained in variable numbers according to the size of the lesion, and from each tissue block a 5  µm section was obtained for microscopically evaluation. In cases of bowel resection the specimen was opened longitudinally through its entire length and 2mm longitudinal bands of bowel wall, reaching the two resection margins and passing through all macroscopically visible lesions, were cut. These bands were sampled in tissue blocks and 5  µm sections were obtained for microscopic evaluation. Statistical analysis Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated for both DCBE and RWC-TVS. The diagnostic value of each test was also assessed using positive likelihood ratio (LR+) and negative likelihood ratio (LR-). Efficacy parameters were calculated with 95% confidence intervals (CIs). McNemars test with the Yates continuity correction was used to compare the accuracy of DCBE and RWC-TVS in the diagnosis of intestinal endometriosis. McNemars test was used to compare the number of patients in which the number of rectosigmoid nodules was correctly identified by DCBE and RWC-TVS. The accuracy of the measurement of nodule size by imaging techniques was estimated by subtracting the size of the nodule as measured by the techniques from the size of the nodules measured at histology. The nonparametric Mann-Whitney test was used to compare the intensity of pain experienced by patients during DCBE and RWC-TVS, the chi-square test was used to co mpare the type of pain (mild, moderate or severe) and Spearmans rank correlation coefficient was used to determine whether there was a correlation between the intensity of pain experienced by patients during the two techniques. Data were analyzed using the SPSS software. p Results Study population A total of 198 patients were enrolled in the study and all underwent surgery were included in this study (Figure 1). The main demographic characteristics of the study are demonstrated in Table 1. The intensity of pain and gastrointestinal symptoms are presented in Table 2. Surgery and histology demonstrated that 110 patients (55.6%) had bowel endometriosis nodules. The endometriosis lesions infiltrating the intestinal serosa in 28 patients. The remaining 82 patients had only pelvic endometriosis with no evidence of intestinal lesions. The largest intestinal endometriosis nodule was found locate on the sigmoid colon in 53 patients, on the rectum in 30 patients, at the rectosigmoid junction in 20 patients, on the ileum in 5 patients and on the caecum in 2 patients. The endometriosis lesions infiltrating only the intestinal serosa were located on the sigmoid colon in 15 cases, on the rectum in 5cases and at the rectosigmoid junction in 3 cases. The mean ( ±SD) length of the resected bowel segment was 12.2  ± 3.6 cm. The diagnosis of endometriosis was confirmed in all the excised nodules by histological exam. Furthermore, it demonstrated that the deepest endometriosis nodule infiltrated the muscularis propria in 62 patients (56.4 %), the submucosa in 3 1 patients (28.2%) and the mucosa in 17 patients (15.5%). Accuracy of RWC-TVS and DCBE in the diagnosis of bowel endometriosis The accuracy, sensitivity, specificity, PPV, NPV, LR+ and LR- of DCBE and RWC-TVS in the diagnosis of bowel endometriosis are described in Table 3. DCBE identified 106 of 110 patients with bowel endometriosis (96.4%). In 4 patients endometriosis nodules infiltrating the muscularis propria of the rectum were not identified, which were excised by partial-thickness nodulectomy. RWC-TVS identified 97 of 110 patients with intestinal endometriosis (88.2%). RWC-TVS did not identify 4 ileal lesions, 2 cecal lesions, 4 sigmoid nodules and 3 rectal nodules infiltrating the muscularis propria. Furthermore, we identified 4 of these patients had large bilateral endometriosis ovarian cysts, which may have hampered the identification of intestinal nodules. There was 2 false positive on RWC-TVS-a rectovaginal endometriosis nodule that was judged to infiltrate the muscularis of the rectum. Surgery confirmed the presence of the rectovaginal nodule but did not reveal infiltration of the rectal muscularis. The sensitivity, specificity, PPV, NPV, LR+, LR- and accuracy of the two techniques in the diagnosis of intestinal endometriosis were shown in Table 3. McNemars test showed that there was no significant difference in the accuracy of the two techniques in the diagnosis of bowel endometriosis (P=0.109). Histology examination demonstrated that endometriosis infiltrated the submucosa or mucosa of the rectosigmoid colon in 53 patients. DCBE correctly identified the depth of infiltration in 27 of these patients (50.9%), while RWC-TVS correctly identified the depth of infiltration in 20 of them (37.7%) (P=0.126). All the other nodules that were seen to infiltrate the submucosa or mucosa at histology were judged to reach only the muscularis at DCBE and RWC-TVS. Both techniques had no cases of false-positive diagnosis of submucosal or mucosal infiltration. Both DCBE and RWC-TVS underestimated the size of the endometriosis nodules; however, the underestimation was greater for RWC-TVS than for DCBE (Table 4). In addition, in both imaging techniques the underestimation was greater for nodules with diameter≠¥30 mm. Tolerability of DCBE and RWC-TVS DCBE was safely performed in all the patients. During both the examinations all patients tolerated intestinal distension and in no patient was it necessary to interrupt the procedure. However, the intensity of pain experienced during DCBE was significantly higher than the intensity of pain experienced during RWC-TVS (Table 5). A positive correlation was observed between the intensity of pain experienced by the patients during the two examinations (Spearman correlation coefficient=0.575; p Discussion To the best of our knowledge, this is the first study demonstrated that DCBE and RWC-TVS have similar accuracy in the diagnosis of bowel endometriosis. Both RWC-TVS and DCBE underestimated the size of bowel endometriosis nodules, but under estimation was greater for RWC-TVS than for DCBE, particularly when the nodules had largest diameter ≠¥ 30 mm (Table 4). The choice of the ultrasonic technique is often based on the experience of the ultrasonographers rather than on evidence of superiority of one technique compared to the others. In fact, TVS must be performed by highly skilled, it has been recently estimated that the learning curve for an accurate diagnosis of deep pelvic endometriosis by TVS requires performing about 40 cases17. Therefore, it may be difficult to achieve such experience for ultrasonographers working in small hospital. The main advantage of DCBE could be that, with a retrograde distension of the entire colon, this technique may provide a complete overview of t he whole colon18. In the current study, the distension was targeted to the rectosigmoid because the aim of the study was the comparison with RWC-TVS and endometriosis lesions of the right colon are beyond the field of view of a transvaginal approach. Furthermore, we did not compare the accuracy of RWC-TVS with TVS alone, which was the objective of a previous study. RWC-TVS was chosen for the comparison with DCBE because of the personal experience of the authors and of the common criterion of bowel distension with fluid. The usefulness of this technique was subsequently confirmed by the same authors in larger series. Furthermore, other authors confirmed that intestinal distension and opacification using ultrasound gel helps to visualize rectosigmoid endometriosis nodules19, 20. Previous studies have suggested that TVS could reliably diagnose rectosigmoid endometriosis. The sensitivity of TVS for detecting rectosigmoid endometriosis is between 91 and 98%, the specificity between 97 and 100%, the PPV between 97 and 100% and the NPV between 87 and 98%21-24. Recently, RWC-TVS has been developed to facilitate identification of intestinal lesions in patients with rectovaginal endometriosis and to determine the depth of infiltration of endometriosis in the intestinal wall25. TVS has been extensively used in patients with bowel endometriosis; while only little data is available on the use of DCBE in these patients. This study demonstrated that DCBE and RWC-TVS have similar accuracy in the diagnosis of bowel endometriosis. Both techniques precisely estimated the length of the rectosigmoid nodules, but DCBE was more precise than RWC-TVS in assessing the distance between the endometriosis nodule and the anal verge9. Obviously, the extensive experience of the radiologi st and the gynecologist in DCBE and RWCTVS, respectively, may have influenced the accuracy of these techniques in diagnosing bowel endometriosis24, 26. The findings may be explained by the fact that when performing imaging techniques, particularly RWC-TVS, it might be difficult to choose the plane in which the irregular endometriosis nodule has the largest diameter. However, the difference between the estimated size of the nodule and the largest diameter as measured on histopathology was quite small and, in most cases, it seems unlikely that this difference would affect the choice of nodulectomy or bowel resection as treatment27. Importantly, patients tolerated RWC-TVS better than they did DCBE. These findings are in line with those of previous studies demonstrating the accuracy of TVS in the diagnosis of bowel endometriosis and comparing TVS with other techniques such as MRI and rectal endoscopic ultrasound11, 28-30. The potential benefits of introducing aqueous contrast medium into the rectum during TVS have been questioned. TVS is an operator-dependent procedure and it is possible that the differences observed in the accuracy of this technique are determined by the experience of the ultrasonographer carrying out the procedure31. However, adding intestinal aqueous contrast to TVS may facilitate the identification of rectosigmoid lesions. Other techniques have been proposed for improving the accuracy of TVS in the detection of deep endometriosis, such as sonovaginography or the use of large quantities of ultrasound transmission gel (12 mL) in the probe cover32. Up to now, no study has established whether any one of these ultrasonic techniques is superior to the others in the diagnosis of deep endometriosis. TVS should be considered the first-line investigation in patients with deep endometriosis, and allows the diagnosis of intestinal lesions24. Other investigations such as RWC-TVS, MDCT-e, MRI, rectal endoscopic ultrasound and DCBE may be used to determine the characteristics of intestinal endometriosis, such as the size and number of nodules, the depth of infiltration of the nodules in the intestinal wall and the degree of stenosis of the bowel lumen33-35. RWC-TVS has several advantages over the other techniques. It is less expensive than MDCT-e and MRI and the equipment required to perform the procedure is commonly available to gynecologists, who are usually involved in the management of patients with endometriosis. A recent study has shown that RWC-TVS allows estimation of the degree of stenosis of the intestinal lumen caused by endometriosis36. Unfortunately, this parameter was not examined in the current study- the major limitation of our investigation. Theoretically, RWC-TVS may also allow determination of the extent of the disease along the longitudinal intestinal axis. Obviously, RWC-TVS cannot determine the presence of intestinal nodules located proximally to the sigmoid because these lesions are beyond the field of TVS. This study had several limitations. First, the experience of the ultrasonographer in RWC-TVS may influence the accuracy of these techniques in diagnosing bowel endometriosis. Second, the surgeons were aware of the findings of DCBE and RWC-TVS. Although in an ideal prospective study the surgeons should be blinded to the findings of the preoperative investigations, this theoretical study design appears unethical in clinical practice because diagnostic imaging may facilitate the identification of intestinal endometriosis nodules during surgery. Furthermore, the knowledge of the findings of the preoperative investigations may only help the surgeons in identifying endometriosis nodules that were actually present. Third, RWC-TVS and DCBE did not estimate the percentage of the circumference of the intestinal wall infiltrated by endometriosis, a criterion used to choose between nodulectomy and bowel resection. Therefore, patients scheduled for nodulectomy on the basis of DCBE and RWC-TVS fin dings should be informed that bowel resection might be required for the complete excision of intestinal endometriosis. Future studies should examine whether DCBE and RWC-TVS can reliably estimate what percentage of intestinal circumference is infiltrated by endometriosis. DCBE may still have a role in the diagnostic workup of patients with suspected bowel endometriosis. When TVS or RWC-TVS demonstrates large intestinal nodules infiltrating the bowel muscularis, bowel resection can probably be performed without further investigation unless the surgeon wants to exclude intestinal lesions located proximally to the sigmoid. In contrast, when ultrasound demonstrates a single bowel nodule that may be excised by nodulectomy, DCBE should be used to exclude the presence of other intestinal nodules and, thus, to adequately plan the surgical procedure with the colorectal surgeon and the patient. Conclusions This study showed that RWC-TVS is a reliable technique for determining the presence and extent of bowel endometriosis and that it has an accuracy similar to that of DCBE. However, RWC-TVS may sometimes underestimate the presence of multiple bowel nodules and can be performed easily in an ambulatory setting and it is better tolerated by patients. It may be hypothesized to combine TVS and DCBE to achieve a complete preoperative assessment of the bowel in order to offer to the patients an adequate counseling and the most appropriate one-step surgical treatment.

In Nazi Occupied Eastern Europe, the Jewish Reaction to the Final Solution Varied :: Papers

In Nazi Occupied Eastern Europe, the Jewish Reaction to the Final Solution Varied The common belief of the reaction of the Jews to the final solution is that they did nothing. Many believed that they went like 'sheep to the slaughter'. However only recently has evidence come to light through documents hidden, found then translated from Russian, Polish and other languages. Also only recently survivors are coming forward and recollecting their experiences. Now it is therefore coming to light that many resisted in many different ways. The Jews resisted in various ways, one of which was passive resistance. One forms of passive resistance was survival. Survival was a form of resistance because it went against the Nazis aim, which was to exterminate the Jews. Examples of the effort of survival were seen in ghettos where food smuggling operations were carried out and also various activities, which supported the will to live and try to add some 'normality' to life. Also another example of the will to preserve life was the Jewish Self Help association, which organised street collections and soup kitchens. The reason for the will to survive is that they believed that they were going to be resettled in the East rather than sent to their death. However if the Jews knew that they were going to be executed many would have lost the will to live, but some it would of given them more determination to resist the Nazis by force, which became apparent around 1942. However the passive resistance and defiance through survival raised morale, due to the fact that they were snubbing and defying the third Reich, which was one of the strongest armies the world has ever seen. Examples of surviving were also seen in the actual death camps where tact and initiative were used to avoid the gas chambers in which Samuel Pisar who was a prisoner a Auschwitz was in the line for entering the gas chambers at which point he saw a pail of water & a brush, he then got them & started scrubbing the floor, until he got out the door he then

They Call Him Mr. Gacy Essay -- John Wayne Gacy Serial Killers Law

There are numerous portraits, perspectives, and analyses of the life and deeds of American serial killer John Wayne Gacy, who is thought to have sexually assaulted and murdered 32 boys between 1976 and his arrest in December 1978 (Cahill, 1978; Gacy, 1989). This profile of Gacy compiles a birth-to-death chronology of events and activities that may lend insight to the personality of a habitual liar, model citizen, and serial murderer. Born to Marion Elaine Robinson Gacy and John Hanely Gacy on St. Patrick's Day in 1942, John Wayne Gacy was the second of three children. The alcoholic Gacy, Sr. was both physically and verbally abusive towards the entire family. His special interest in John, Jr. was the litany that he was 'dumb and stupid' and an embarrassment to the family. However John Jr. loved his father and strived to please him. John suffered poor health during much of his childhood. After attending four years in high school John Jr. dropped out leaving home for Las Vegas. He worked odd jobs to include a maintenance position at a funeral parlor. There were few decent jobs available in Las Vegas for John Jr., so he saved up enough money to move back to Chicago. Returning to Chicago in the early 1960's he graduated with a degree from a business college. His first job was as a sales person at Nunn-Bush Shoe Company. Quickly moving up in the company, he was soon transferred to a men?s clothing outlet in Springfield, Illinois and promoted to a management position. John Jr.?s took an active interest in the community and became a respected member of several community organizations: the Chi Rho Club as chairman, the Catholic Interclub Council as a member of the board, the Federal Civil Defense for Illinois, Chicag... ... shock A.

Conditioning: Psychology

Learning is an important skill that all organisms must acquire in order to survive or fall prey to Darwinism’s main idea of survival of the fittest. Learning is the long lasting effect of a change in behavior. This would constrict the application of learning conditioning to a few applications. The three most recognizable applications are classical conditioning, operant conditioning, and learning by observation. Each type of learning is different, but uses similar ideas such as an unconditioned stimulus, which is usually food, and an unconditioned response, which food is associated with salivation and hunger. There are several ways that an individual can condition an organism to learn skills through three different applications of learning: classical, operant, and observation. The idea of classical condition is one of the most notable learning techniques because it involves a stimulus rewarded for a certain response. Naturally, animals and human have unconditioned stimulus that triggers an unconditioned response. The most common connection is the correlation between food and salivation. Food naturally draws organism to it in order to satisfy a drive created by hunger to acquire homeostasis. A response is created because of the organism’s reaction to food, which is usually salivation. Classical conditioning is considered an effective way to train an organism to learn habits not naturally associated with certain unconditioned stimulus. This creates a conditioned stimulus. The once unconditioned response is now conditioned to respond to the conditioned stimulus, which is called a conditioned stimulus. An example of conditioned stimulus and response is the example of associating the school bell with food. Children are hungry by nature, but when the school bell is added, the children are reinforced to associate the school bell with lunchtime. Classical conditioning is effective when trying the teach an organism a skills by rewarding the organism with a unconditioned stimulus. An individual could use classical conditioning to teach an organism to learn skills that could aid in their own survival such as teaching human to avert certain food because of taste. If one were being taught to avert away from sour tastes, the teachers would first use a food that was extremely sour. By using the person’s innate instinct of hunger, they would give the person a lemon to eat. This sour extremity would cause the person to avoid lemons. The teacher would continuously use this tactic until the person has acquired the skill of aversion of lemons. The learner would have an acquisition of the skill. The teacher would then condition the learner in a variable interval to constantly reinforce the skill. The learner would then avoid all lemons. This may cause the learner to generalize the concept of lemon, for example, the learner may generalize the yellow color to symbolize all sour products, such as generalizing bananas as being sour. The teacher would then have the obligation of teaching the person how to discriminate items, so that his aversion is just towards lemons. While classical conditioning involves the stimulus being rewarded to incur a response, operant conditioning deals with changing the occurrence and forms of behavior. The main different between operant conditioning and classical conditioning is the operant conditioning deals with modifying the learner’s voluntary behavior. Operant conditioning involve consequences to teach desired skills. There are two ways that operant conditioning works, through reinforcement and punishment. Reinforcement comes in two flavors: positive reinforcement and negative reinforcement. Positive reinforcement is the teacher adds something of pleasure to the learner’s behavior in order to get a certain skill. An example would be a mom allowing her child to play video games if the child put the trash outside. The mom uses the favorable stimulus, which is the video games, in order to achieve a behavior, which is taking out the trash, out of the child. There is also negative reinforcement, in which negative reinforcement is the teacher removing an aversive stimulus, which is usually seen as unpleasant, in order to increase the frequency of a certain behavior. For example, when someone wakes up early in the morning, they use an alarm clock to tell them when to wake up. When the alarm clock is activated, it sends a signal, which is usually an annoying buzzing noise, to the learner that it is time to wake up. To reinforce the behavior of waking up, the learner must get up from bed to turn off the aversive stimulus. Reinforcements are consequences of reinforcing favorable behaviors. Punishments, on the other hand, are consequences in which the teacher tries to reduce the frequency of unfavorable behaviors. As with reinforcements, there are also positive and negative punishments. Positive punishment refers to occurred behavior followed by aversive stimulation, such as shock. An example of positive punishment would be if a child had talked negative to the mom, and the mom would respond with a slap on the wrist in order to lessen the frequency of such behavior. Negative punishment, on the other hand, is the removal of a pleasurable stimulus after the occurrence of an undesirable behavior. As with the example of the mom, and the child taking out the trash, if the children had not taken out the trash, the mom would instead take away the video games to lessen the frequency of not taking out the trash. The problem with punishment is that it may cause the learner to demonstrate bad behavior in response to the punishment through responses of fear or anger, rather than lessen the occurrence of the aversive behavior. Operant conditioning is more effective using reinforcements than punishment. However, using both facets successfully is the most effective way. An individual could teach another through operant conditioning if one would like to change a voluntary behavior in another. The teacher would have to use reinforcements to reinforce the desired behavior from the learner. For example, if the individual wanted the learner to wash the dishes after eating, the individual would have to give an incentive to the learner in order for the behavior to continue, such as letting a child play video games after completing his chores. The continuous stimulation by the positive reinforcement would allow the learner to associate good behavior with pleasurable activities. Once the learner has acquired the behavior, the learner may generalize the behavior to include doing all his chores in order to gain the positive reinforcement. The teacher would use punishment sparingly to lessen the frequency of aversive behavior such a taking away the video games. The way that an individual could instruct an organism to acquire a skill is through observable learning. Observable learning is the observations made by the learner through the actions of the teacher in order to create a skill, or change a behavior. Observational learning is the most commonly used tactic. It allows the learner to learn a skill without reward or consequences. The learner learns through observing the teacher and then imitating the actions of the teacher. This is a more common tactic to teach child skills that are learned and reinforced throughout their adulthood, such as table manners. The individual could teach an organism how to do a skill through observational learning. The individual would do an act that is observed by the learner, and they would have the learner imitate the actions. For example, a mother would like to teach her child table manners. She would demonstrate proper table manners to the child. She would then have the child repeat and imitate her actions. Once the child has acquired that knowledge, the mom would continuously reinforce the behavior. The child would learn table manners without much need for punishment or reinforcers. The way that observational learning works, some may categorized observational learning as operant conditioning because it usually involves changing behaviors. The individual could use these three conditioning techniques in conjunction with each other, in combination with them, or separately. Either way, these techniques, classical conditioning, operant conditioning, and observational leanring, are the effective way to show an organism how to learn skills.
