About the U.S. House of Representatives

About the U.S. House of Representatives The United States is a large, fractured, diverse and yet still unified nation, and few government bodies reflect the paradox that is this country better than the House of Representatives. Key Takeaways: U.S. House of Representatives The House of Representatives is the lower chamber of the two legislative bodies in the United States federal government.The House is currently made up of 435 representatives- referred to as congressmen or congresswomen- who serve an unlimited number of two-year terms. The number of representatives from each state is based on the state’s population.As required by the Constitution, representatives must reside in the state from which they are elected, must have been a U.S. citizen for at least seven years, and be at least 25 years old.A representative’s primary duties include introducing, debating, and voting on bills, proposing amendments to bills, and serving on committees.The House has the exclusive powers to initiate all tax and spending bills and to impeach federal officials.   Metrics of the House The House is the lower of the two legislative bodies in the U.S. government. It has 435 members, with the number of representatives per state dependent upon that states population. House members serve two-year terms. Rather than represent their entire state, as Senate members do, they represent a specific district. This tends to give House members a closer link to their constituents-and more accountability, since they have but two years to satisfy voters before having to run for re-election. Also referred to as a congressman or congresswoman, a representative’s primary duties include introducing bills and resolutions, offering amendments and serving on committees.   Alaska, North Dakota, South Dakota, Montana and Wyoming, all sprawling but sparsely populated states, have just one representative each in the House; tiny states like Delaware and Vermont also send just one representative to the House. By contrast, California sends 53 representatives; Texas sends 32; New York sends 29, and Florida sends 25 representatives to Capitol Hill. The number of representatives each state is allotted is determined every 10 years in accordance with the federal census. Although the number has changed periodically through the years, the House has remained at 435 members since 1913, with shifts in representation occurring among different states. The system of House representation based on district population was part of the Great Compromise of the Constitutional Convention in 1787, which led to the Permanent Seat of Government Act establishing the nations federal capital in Washington, DC. The House assembled for the first time in New York in 1789, moved to Philadelphia in 1790 and then to Washington, DC, in 1800. The Powers of the House While the Senates more exclusive membership may make it seem the more powerful of the two chambers of Congress, the House is charged with a vital task: the power to raise revenue through taxes. The House of Representatives also has the power of impeachment, in which a sitting president, vice president or other civil officials such as judges may be removed for high crimes and misdemeanors, as enumerated in the Constitution. The House is solely responsible for calling for impeachment. Once it decides to do so, the Senate tries that official to determine whether he or she should be convicted, which means automatic removal from office. Leading the House House leadership rests with the speaker of the house, usually a senior member of the majority party. The speaker applies House rules and refers bills to specific House committees for review. The speaker is also third in line to the presidency, after the vice president. Other leadership positions include the majority and minority leaders who monitor legislative activity on the floor, and the majority and minority whips who ensure that House members vote according to their respective parties positions. The  House Committee System The House is divided into committees in order to tackle the complex and various matters on which it legislates. House committees study bills and hold public hearings, gathering expert testimony and listening to voters. If a committee approves a bill, it then puts it before the entire House for debate. House committees have changed and evolved over time. Current committees include those on: agriculture;appropriations;armed services;the budget, education, and labor;energy and commerce;financial services;foreign affairs;homeland security;House administration;judiciary;natural resources;oversight and government reform;rules;science and technology;small business;standards of official conduct;transportation and infrastructure;veterans affairs; andways and means. In addition, House members may serve on joint committees with Senate members. The Raucous Chamber Given the shorter terms of House members, their relative proximity to their constituents and their larger numbers, the House is generally the more fractious and partisan of the two chambers. Its proceedings and deliberations, like those of the Senate, are recorded in the Congressional Record, ensuring transparency in the legislative process.

Modern Drama essays

Modern Drama essays Modern drama began by turning toward realism and away from the fantasy of nineteenth-century melodrama and farce. Realism gave rise to various innovations that served to express the dramatists vision of what reality is. These attempts to be more real than real can be called expressionism. Realism and expressionism are the two dominant modes of drama in the twentieth century. One focuses on the external details of everyday life, while the other focuses on the mind and feelings and tries to show how The word drama comes from the Greek word dran, which means to do or to act. Besides being traditionally literary, the drama is a theatrical form. Dramatist do not usually write with the purpose of communicating directly to the reader, as do fiction writers, poets, and essayists. Instead, dramatists ask people of the theater-actors and actresses, directors, set designers, and others- to assist them in communicating to the audience. Good dramatists are aware of the resources and limitations of their medium. They recognize that they must tell their stories in a different way from novelists. Dramatists attempt to construct meaningful works in two ways: by the precise and evocative use of words, and by careful attention to basic structure. The Greek philosopher Aristotle, in writing a treatise based on the plays of his time (the fifth century B.C.), defined drama as an imitation of an action, a definition which has become the basis for most subsequent dramatic criticism. To take the last word first, by action Aristotle meant not merely activity or exertion, but rather the direction the play moves in, the closely related series of events that give the play its momentum. A play, in Aristotles terms, must have a plot with a beginning, middle, ...

Discuss the impact of industrialization in 18th century Britain Essay

Discuss the impact of industrialization in 18th century Britain - Essay Example This was an encouraging wave for everyone around as they started to invest more, search more, invent more and got involved in much more economic activities than the past history. During the 18th century, through industrialization, the average income increased to over 10-folds especially in Great Britain. This was due to the ingenious inventions of machine based manufacturing that put the manual labor to rest and saved time and animal labor. This increased the rate of mining, textile production and helped in revolutionizing iron making methods. This industrial growth helped in creating trade routes within the country and outside of Great Britain during the 18th Century. The industry of railways and roads then went on a boom as through steam engines that helped in having faster trade as well as elevated the production, which helped in creating more jobs and more income for the people of Britain. 1 As people mostly wanted to live near their jobs, the concept of Urbanization then occurred and housing started to become more modified and work oriented. As the communication structure through roads was still going under the industrialization phase, people needed to be near to their jobs for faster access and more productivity. Mentally and socially, industrialization had a larger impact. While British public was starting to grow the malnutrition was becoming a problem. With having life expectancy of 35 year before the industrialization era, this Malthusian trap was then soon recovered through better agricultural practice and the life expectancy was increased to 40-45 years of age. Socially the per capita income through many other jobs increased and people around Britain started to live a prosperous life as compared to the 17th Century. Now having better housing facilities as compared to when people lived in shanties and shacks, this changed the people who moved into the

Does the Mission Statement or Vision of the firm reflect the companys Case Study

Does the Mission Statement or Vision of the firm reflect the companys focus on customers - Case Study Example As such, without a clear focus on the consumer, for those interested parties who review the mission and or vision statement, the emphasis that the firm places n achieving a degree of customer loyalty and/or customer satisfaction is something that is not referenced at all. In this way, the firm could most certainly benefit from a recalibration of the mission statement and vision that it currently displays (Zara 2011). Although it is heartening to see the that the firm pays such a great deal of attention to the environment and environmental concerns, completely ignoring the role and importance that the customer plays with relation to the business model is perhaps shortsighted. Description of the career you considered and why you found it attractive. Choose one describe what academic degrees, business experience, language skills etc that you will need to be successful. After reviewing the great diversity of careers that are available to the individual interested in a career in marketing, I was particularly drawn to a career in public relations. Public relations and market outreach is a field that interests me because it goes beyond merely marketing a product and directly incorporates elements of social interaction and company representation. In such a way, the individual who works within such a career is ultimately responsible for seeking to challenge public opinion and represent the firm/organization in time of difficulties and in times of success. Ultimately, it is the challenge of such a position that is attractive due to the fact that many individuals employed in public relations type marketing jobs have had the distinct ability to fundamentally alter the means by which the public views the firm and the ultimate product or service offerings they represent (Laskin 2012). Such is not the norm however but it is a possibility for the individual tha t works in such a field. With respect to the particular type of skills and knowledge that is required for such a job, the website that was analyzed to inform his report stated that a degree in good standing from a four year university or college was ultimately a requirement. Furthermore, although there was no experience requirement for beginning within such a career, ultimately representing the firm to the public would be something that would most certainly require much experience as well as supreme command of verbal and written skills and exceptionally high quality people skills. Q3) What kinds of jobs are available, where are the jobs available, what types of skill sets are required for international marketing jobs For the most part, the types of marketing jobs that were represented were entry level with the remainder being upper level management positions. As such, there were very few offerings for individuals within the middle of their career with a reasonable modicum of experie nce. Moreover, the types of jobs centered on promotions and individual store marketing. When building the search query for this particular part of the assignment I wanted to have one that was as broad as possible so that it would be certain to capture even the international opportunities that exist within the field. Almost without exception, the greatest number of international job openings was with relation to the

Total Information Network Essay Example for Free

Total Information Network Essay Total information is a paradox; no one library or resource can serve the need for scholarly pursuits though a network of such is gradually moving toward satisfying particular informational needs. The recent times are a witness to increased cataloging and documentation- which in time will be part of historical documents and databases. There is a particular inclination toward the use of the internet for informational necessities that, though not an all-inclusive resort, accords one the flexibility the modern world demands. Students and academicians benefit from the online resources at their disposal. Online libraries such as questia.com and bibliomania.com are gaining popularity from a scholarly clientele because of the flexibility it can accord one from using those online resources. Questia.com boasts of over a million journals and tens of thousands of books in fields from architecture to law, economics to psychology etc. Tools such as the encyclopedia and thesaurus, along with newspapers and magazines in their reading room, are extra amenities. Bibliomania.com has a voluminous collection of fiction, drama, poetry, and short stories, and non-fiction, biographies and religious texts in its domain. In addition, study tools such as study guides and references are part of the package.   Ã‚  Ã‚  Ã‚   On a more complex note, the online library libraryspot.com is connected to an even wider array of libraries- online, academic, government, public, state, law and medical libraries for one’s research needs. The online government libraries give one access to the National Archives, the Library of Congress, the Internet Law Library, the White House Press Room, National Library of Education, National Library of Medicine, National Agricultural Library and the Air Force Library. As an example, the National Archives (archives.gov) allows for an exploration of federal research documents (legislative, executive and judicial), research and order, America’s Historical Documents and presidential files. The Library of Congress (loc.gov for the online counterpart), being Congress’ research arm and â€Å"the oldest federal cultural institution† is the largest library in the world and has for its collection millions of books, manuscripts, maps, photographs and recordings. The online academic libraries give one access to select university libraries per state (e.g. Indiana University in Indiana and Columbia University in New York) that have their own collection of books, journals, dissertations and other documents along with regular library materials. The public libraries portal is connected to PublicLibraries.com, Libweb, UK Public Libraries and the Public Libraries of Europe- all of which are online. The state libraries section channels you to state-specific libraries with public records on population censuses, marriage indexes, family and local histories, military and pension information, and cemetery location files. The National Library of Medicine online and Medical Libraries online, and the Law Library Catalogs online, the Law Library of Congress online and the American Association of Law Libraries online, are cached under the medical and law libraries, respectively. Access to these online libraries is usually free, although some require a login ID and password.   Ã‚  Ã‚  Ã‚   For a model, the Walden Library is an excellent resource. It has a wide array of articles, books, dissertations, government resources and textbooks which one could get from Walden databases, local libraries, commercial sources and by document delivery. Walden University’s Document Delivery Service is a unique feature that allows researchers to borrow books and obtain materials’ photocopies owned by the IU-Bloomington Libraries. Registration is a requirement, and an email with a username/password will be forwarded to the subscriber. Materials requests can then be submitted (e.g. books, photocopies) after checking on an IU-Bloomington ownership from the online catalog. The service is free but typical delivery time is 7-10 days or longer and there is an assumption of responsibility for the book’s return amidst any circumstance. The Walden Library even has a portal connected to other local libraries, online bookstores and commercial sources, should the requested material prove to be inaccessible. A portal linking one to the librarian, should one have particular queries, is also an amenity.   Ã‚  Ã‚  Ã‚   Building a total information network need not be an impossibility!

Development Changes of Renal Tubules

Development Changes of Renal Tubules Development changes of Renal Tubules from Neonates to Adults for its function Introduction Term infant means a newborn child within 28 days after birth. Nephrone is the functional and structural unit of kidney. Each nephron is made up of narrow tube that specializes in ( renal tubule ) secretion and reabsorption pre-filter unit ( renal corpuscle ). It provides a small solutes and water in tubule structure, renal corpuscle excludes solutes from blood. these renal tubules does not function in adult levels at neonatal period. Because at birth, kidney is immature. It develops with age and reaches to the adult functioning level after some time. This short analytical essay describes about the development of the renal tubules from neonates to adults for its function: that means how the renal tubules develop and adapt to their function with age. 1. Who is Infant? From the Latin meaning of infans or can not tell and say , infant is very young children of a human or animal. If you apply in person, this term is usually considered equal to the child. It may be to learn that human child walks, is used in place long walks . Term infants will be used for infants up to the age of the moon 12 months and one month usually. However, it is possible to define the birth, it varies between 2 years and birth, or between one year. Child for several hours at only very young, several days, or up to a few weeks ago. In medical condition, ( from the Latin, neonatus, newborn ) newborns and infants, in the first 28 days after birth, it means infant, this term applies hypermature Early Childhood, infant, full -term infants . 2. Functions of the kidney Excretion of waste The kidneys excrete the various products of waste by metabolism. These include, ,, nitrogenous wastes called urea from protein catabolism, such as uric acid, such as this from nucleic acid metabolism. The formation of urine, it is the function of the kidney. Accumulation of nitrogenous waste in the urine of birds and some mammals, rely on elaborate countercurrent multiplication system. This requires the nephron function of the independent functions of several . Re- absorption of essential nutrients Glucose plasma levels, re- absorption in the proximal tubule is completely normal. Is reabsorbed in the proximal tubule, amino acids are sodium-dependent transporter . Acid-base homeostasis Maintain the acid-base homeostasis is to maintain the pH value near the organ systems of the two kidneys, lungs, stabilized. Very important role of the two in the maintenance of acid-base balance and kidney : Re- absorption of bicarbonate from the urine, to discharge the hydrogen ions in the urine Regulation of blood pressure Kidney can not be used to directly detect blood, but long term control of blood pressure is dependent on the kidney mainly. The size of, is performed via the maintenance of theextracellular water compartment depends on the plasma sodium concentration this . Hormone secretion And kidney secret type of hormones such as erythropoietin, enzyme renin. ( Low levels of oxygen at the tissue level ) release erythropoietin in response to hypoxia in renal circulation. It is to stimulate the ( production of red blood cells ), red blood cell production in the bone marrow . 3. Nephron Renal corpuscle Configure the Bowmans capsule and glomerulus, renal corpuscle is the commencement of the nephron. It filters the parts of the original nephron. Tubule It is a part of the nephron, including water filtration cylindrical through glomerulus.After through the tubule of the renal tubules, and continues to collect, the duct system that is not part of the nephron is the filtrater. Function of the renal tubules, is listed on the page XX Collecting duct system The first part is a small tube connection system of collecting duct, it provides the flow-through for each distal tubule. Collection of the duct system begins with the renal cortex and medulla to the deep. Urine so that down the collection duct system, passes the gap marrow with a high sodium concentration because the loop of henle is a countercurrent multiplier system. Juxtaglomerular apparatus Angiotensin system production of the enzyme renin involvement and juxtaglomerular apparatus is a specialized area of nephron cause of renin secretion to . 4. Functions of various segments of Renal Tubule The type of renal tubule, and is part of the filtration nephron from the glomerulus. It is composed of the following elements: 1 .proximal convoluted tubule 2. Loop of Henle divided into three: thin descending limb loop thick ascending limb 3. Distal tubule 4.Collecting duct Proximal tubule (PCT) In the first part of the renal tubule, near corpusle kidney, which is lying on the cortex of the kidney. The filtered water from the Bowman capsule enters the proximal tubule. Has a brush border, which has been designed to cubiodal epithelium. It has eosinophilic cytoplasm due to the number of mitochondria . Work of PCT PCT is, H2O If you re- absorb 2/ 3 ( percent 65-80 and Na) or, filtered glucose, and this is, to re- absorb all amino acids Na glucose is re- absorbed by the co-transport of Glu The section, I resorb potassium bicarbonate, calcium phosphate Thin descending loop (TDL) I reabsorb water (H 2 O) passively it is impermeable to sodium (Na) I will allow a hypertonic urine in the TDL, urine is concentrated Thick ascending loop  and, in this part of the loop, CL and K is reabsorbed actively This does not transmit H2O In this section, urine is a low concentration Distal tubule This part of the tubules are lined with a simple cubic epithelium with Musuri-ko edge The re- absorption of sodium chloride actively , This secrete hydrogen ion and ammonium ion . be part of the juxtaglomerular apparatus Collecting duct Is on the CD, and is performed through the cortex to the medulla and leads to renal papilla. The epithelium is different in cubic columnar epithelium with ( almost nipple ). This is the last part of the renal tubule. It has two types of cells . 5. The Renal Function in Neonates Compared with adults, renal function, and is changed newborns. Complete structure in terms of the number of nephrons of 36 weeks, but the baby of the kidney is functionally immature still. Renal function is subject to rapid maturation in postbirth during the first week of both of preterm infants with time. Because I control the balance of water and electrolytes at that time, a small amount, because of the extremely low birth weight infants, and there was especially. Overhydration, dehydration, and the biggest risk for children, contains the electrolyte imbalance . It is possible to maintain a normal state, the homeostasis of the kidney after birth. However, infants early, most can be less, which is to maintain the water balance of the normal electrolyte, or bicarbonate. To maintain homeostasis, the control of renal blood flow and glomerular filtration plays an important role in determining the ability of the kidney. The biggest factor that determines the renal function is probably maturity. Renal formation, up to 34 weeks of pregnancy is not complete. In particular, under the glomerular filtration, and absorption and filtration of the kidney, which has a significant effect on the hormone-sensitive nephron control . 6. Renal Function of the Elderly Including glomerulosclerosis a decrease in size of the kidney, increased vascular changes and arterioles, the type of anatomical defect in the aging kidney, have been identified. Also physical changes, including a decrease in renal blood flow, decreased glomerular filtration rate, tubular framework of the kidney, the shape of the endocrine renal function, are described. From one point of treatment by a physician or disease, clinical outcome of these changes is the ability of the kidney -shaped age to cope with stress. Vigilance and special care is needed when you take care of the elderly . 7. Renal Function in Relation to the age In comparison, the growth and food intake of adults in maintaining the biochemical stable environment, when it is more important for infants than kidneys. Infants, kidneys are developing with the normal function of the ` s properly. However, it is very adaptable to emergency THN in adults. It is not present in urine excrection rhythm birth of a normal adult. These have been developed within a few years. GFR is a baby less than adults. However, the proportion of adult products and to compare, this low GFR is enough to excrete a small amount . 8. Structural changes of Kidney with age The number of structural change takes place in the kidney of aging. Kidney of aging is characterized in that the number of news kidney, vascular sclerosis, hyaline artery disease, hardening of glomerular increases, tissue fibrosis and renal tubules is lost. Pathogenesis of structural changes associated with aging are not fully understood. Both the hemodynamic factors and genetic background, are associated with the development of physical changes associated with age. Structural changes in the aging kidney, is a non-specific, diabetes and be seen in many situations, including high blood pressure, such as a, and, can, is a diagnosis of exclusion is arterionephrosclerosis aging Decline associated with aging, host of the structure and function of the kidney. Might disrupt the assessment of the impact of aging on renal function, appreciation and selection of the population, the problem, methodological, which led to the re-evaluation of recent. Well as a decrease in renal function protected areas, the common denominator of these changes, is the subject of kidney of either excess or defect of constraints and the ability to respond appropriately. These changes, to achieve clinical significance when the residual renal function was challenged by the superposition of acute disease, under the conditions of day-to-day, but there is likely to have a major clinical results. Finally, often amplify these drawbacks whereby, elderly patients should be emphasized may be a change in the aging and addition, can co-morbidities, such as heart disease or high blood pressure, suffer . 9. Functional changes of Kidney with Growth Renal function, started the development of a program ,It continues to evolve in the first year of life Full adult rate. Under this process, the responsible kidney Changes and to provide renal function during childhood, in particular the Characteristics. Human kidney to begin the development in five Started production of urine between the pregnancy and the 10th week 12 weeks of gestation. It was completed in around the 36 week from 35 to newborn long-term kidney formation, but are born with a nephron all of its What is not a case of one of the initial born before, Renal formation is complete. Entire process of fetal kidney The progress to be regulated by many genes have recently been shown For example, as cytokines and growth factors such gene products and, Intrauterine environment itself in a special process known as, Epigenetics. Kidney regulates homeostasis to the basic operation of the two, Glomerular and tubular. It is the work of all neonatal although neonatalkidneys flaws and i s equipped with, Of them to develop a physiological process, is severely limited The response to stress. Infants having a glomerular filtration rate (GFR) Was increased stepwise to achieve, the low and 20 ml/min/1.73 m ², at birth Adult levels at 18 months. Completely new nephron has not been played in childhood, but is available in sizes from increasing, I mature in the workplace. Tubular function and glomeruli, but may mature level Between 12-18 months, kidney child maintaining a low capacity for dealing with residual Susceptible to trauma of childhood .Started developing early, renal function, twisted creature Evolution in the first few years of his life full, to adults Level. Under this process, is responsible for changes giving kidney Kidney Function in the reputation of his childhood and childhood somewhat. But From, the main challenge for developing kidney events of the migration I adjust the uterus to life outside the womb, the homeostasis of the continuous for Organisms c hildhood and growing during childhood are also sought . 10. Developmental changes of Renal Tubules for it`s Function If you have corrected the size of the body, starting in stages it, remains relatively constant 4 of life up to 10 years old, shows the age of 1 year and kidney capacity fully functional, standard of renal function a decline in the use of age-related indicators, the glomerular filtration rate such. Be predicted without knowledge of the exact mechanisms involved Avoid reabsorption and tubular secretion of positive and negative ions in order to provide an opportunity for drug interactions is difficult. Data to support the development changes in the net tubular secretion of several items. For digoxin, clearance of digoxin observed in children during puberty, most of the creatinine clearance is reduced at a rate under consideration in adults, this decrease, and more mature than the age of the annual, and more there is a good correlation. Renal excretion of metabolites and active drug and a very important medicine provides important clinical information definition of the mechanism of renal tubular net . In preterm infants, secretion tubular reabsorption and organic acids certain amino acids, and potassium hydrogen ion is a relatively immature at birth in particular, was increased as a function of postnatal age. As part of the animal and continuous, immature state, on the other hand, the ability of phosphate reabsorption is enhanced when you adapt to their environment. In the case of glucose, under 34 weeks, transport system is relatively mature at the time of the infants so during pregnancy. One, as well as the treatment of pharmacological preterm infants tubular transport amino acids development, potassium, phosphorus, and nutrition, in the evaluation of long-term, you need to consider organic acid, these changes. Adult levels is different from ability and dilution capacity of the urine should be considered. To dilute the ability to be in the ability to take into account the fact that normal adult level three months and level of adult 14th. The ability to excrete water load reached adulthood at the end of January. Inability to concentrate urine at the level of the adult is due to it is impossible to correspond to the ADH The inherited microtubules and a small amount of ureThis article has reviewed the maturation of major renal tubular transport systems. The tubular reabsorption of certain amino acids and the secretion of organic acids, hydrogen ions, and potassium increases as a function of postnatal age, being relatively immature at birth, especially in the preterm infant. In contrast, the ability for phosphate reabsorption is enhanced during the immature state as the developing animal attempts to adapt to its environment. In the case of glucose, the transport system is relatively mature in the term infant and less so in the infant of less than 34 weeks gestation. One should consider these developmental changes in the renal tubular transport of amino acids, potassium, phosphate, and organic acids in the nutritional assessment and pharmacologic treatment of p reterm as well as term infants.

Observing Animals And Documenting Specific Animal Behavior Patterns

Introduction: The broader context of this lab was aimed at observing animals and documenting specific animal behavior patterns. Specifically, we were trying to determine if squirrels applied snakeskin randomly to certain areas of their body or if there was a specific technique to it in relation to escaping their predators. After an animal has determined that a predator is nearby, it must then take action to avoid encountering this threat.Encounters are most easily avoided by preventing predators from detecting prey in the first instance (Rosier & Langklide, 2011), for squirrels this type of behavior is known as SSA, â€Å"snake scent application†. In this lab we wanted to study two different species of squirrels, S. beecheyi and S. variegatus, in order to evaluate if SSA can be deemed as a species specific type of behavior. My hypothesis was that squirrels applied the snake skin scent to specific parts of their body in an organized manner. The null hypothesis is that squirrels apply the snake skin scent randomly to parts of their body.My prediction of my hypothesis was that squirrels apply the snake skin scent to body parts that they find prove to be advantageous when trying to escape their predators. Methods: We watched videos of both species S. beecheyi and S. variegatus applying the SSA to their bodies. We were allowed to choose four videos from each species. Each video showed a squirrel applying the snake skin to their body within their own natural habitat. Some videos had more squirrels while others showed just one individual squirrel.In this lab we were given a table where we had to record how many times SSA was applied to a specific part (flank, head, front leg, hind leg, tail) of the squirrel’s body. My partner and I chose to assign one person to tally the frequencies to each part of the body while the other watched the video and observed the application. I chose to do the observing, while my partner recorded. Every time a squirrel appeare d to be licking or touching a certain body part was considered a tallied frequency, however, the squirrel had to be doing so for at least three seconds in order to be recorded.Results: The table below (Table 1) shows the recording of the total frequencies that were tallied after seeing the squirrels apply the SSA to the respective specific body part. I included the total data in order to clearly show what I used for my calculations. In order to interpret our results we had to use the chi-squared test. This test compares the observed behaviors to the expected behavior if it was randomly distributed, also considered to be the null hypothesis where SSA is applied randomly on the squirrel’s body.From using the chi-squared equation (shown to the right), I calculated the expected frequency for each species, 12. 6 per area for the S. beecheyi and 10 per area for the S. Variegatus. The chi-squared values for both the S. beecheyi and S. variegatus were 70. 13 and 65, respectively. For this lab experiment there were 5 independent pieces of data, therefore 4 degrees of freedom. Given that piece of information we were able to look up the critical values at a confidence of 0. 05 and 0. 01, which were 9. 488 and 13. 277, respectively.The chi-squared value for both species exceeds these values and therefore we can reject our null hypothesis that states SSA is applied randomly. Discussion: Although we were able to accept our hypothesis, there is always room for improvement. The process of observing the squirrels and recording the amount of times SSA was applied may have greatly affected the results if not done properly. It was important to determine if the squirrels were in fact applying the SSA, this proved to be difficult during the experiment.In addition, determining whether it was flank or hind leg also proved to be difficult. Since we were able to reject our null hypothesis, we were able to accept our hypothesis that SSA is applied non randomly. The values that we derived from the chi-squared test helped support our hypothesis; we can then conclude that squirrels have a specific technique and process when applying snakeskin to their body. As I predicted these areas that they are constantly applying the snake skin scent proves to have a certain preference to them.We can imply that their preference is based on the idea that certain body parts are more vulnerable or do a great job at masking their scent, therefore hiding well from their snake predators. This is something that has evolved over time, snake-scent application is likely a product of natural selection. Squirrels that had the genetic instinct to use the ploy might have had increased survival and reproductive success, thus passing the trait to following generations (Goudarzi, 2007). I think it would be really interesting to look at different age groups within the squirrel population and their application process.This can help us find out whether squirrels at different stages in their l ife (young and old) find themselves to be more or less vulnerable and hence apply a lot or little of the SSA to specific areas of their body. It is also important to study different species of the squirrel population. I believe that different environments lend to different processes and techniques. If given the opportunity, I would do research on at least 8 more species that are completely different in their geographical regions and environment (dry vs moist areas) to each other.

Use of Wireless local area network

AbstractionIn many sectors wireless local country web ( wireless local area network ) has been widely used.mobility, scalability, easiness of installing, reduced cost-of-ownership, installing flexibleness are the grounds were wireless local area network gained popularity.WLAN have some security menaces apart from the benefits mentioned above.the scenario begins by presenting the construct of WLAN, and how wired tantamount privateness ( WEP ) works, which is the IEEE 802.11b/WIFI standard encoding for radio networking.Examining WEP failing, it is being much less secured than what was orginally intended.further research sing practical solutions in implementing a more secured radio lan.new criterions excessively better the security of wireless local area network such as IEEE 802.1X criterion, comprises of point to indicate protocol ( palatopharyngoplasty ) , Extensile Authentication protocol ( EAP ) and 802.1x itself.802.1x is included in 802.11i, a new criterion for cardinal distributi on and encoding that will play of import function in bettering security capablenesss of future and current radio local area network networks.802.11i criterion provides WEP To be replaced by two encoding algorithms, which are ( TKIP ) Temporal cardinal unity protocol, ( CCMP ) cbc-mac protocol.1.Introduction to WLANTo utilize either infrared or radio frequence engineering to convey and have information over the air, flexible informations communicating system called wireless local country web ( wireless local area network ) is used.802.11 was implemented as the first WLAN criterion in 1997.it has a maximal througput of 1 to 2 mbps and operated in 2.4 gigahertz frequency.IEEE 802.11B is the most dispersed and deployed criterion, was introduced in 1999.the maximal velocity is 11mbps and frequence scope is the same.sectors from instruction, corporate, warehousing, retail, health care, finance WLANS has been used widely.the demand for installing flexibleness, scalability, cost-of-ownershi p, mobility wireless local area network has been an of import engineering to fulfill.2.0 Security Threats of WLANDespite the productiveness, convenience and cost advantage that WLAN offers, the wireless moving ridges used in wireless webs create a hazard where the web can be hacked. This subdivision explains three illustrations of of import menaces: Denial of Service, Spoofing, and Eavesdropping.2.1 Denial of ServiceIn this sort of onslaught, the interloper floods the web with either valid or invalid messages impacting the handiness of the web resources. Due to the nature of the wireless transmittal, the WLAN are really vulnerable against denial of service onslaughts. The comparatively low spot rates of WLAN can easy be overwhelmed and leave them unfastened to denial of service onslaughts [ 9 ] . By utilizing a powerful plenty transceiver, wireless intervention can easy be generated that would unable WLAN to pass on utilizing radio way.2.2 Spoofing and Session HijackingThis is where the aggressor could derive entree to favor informations and resources in the web by presuming the individuality of a valid user. This happens because 802.11 webs do non authenticate the beginning reference, which is Medium Access Control ( MAC ) reference of the frames. Attackers may therefore spoof MAC references and highjack Sessionss. Furthermore, 802.11 does non necessitate an Access Point to turn out it is really an AP. This facilitates aggressors who may masquerade as AP? s [ 9 ] . In extinguishing spoofing, proper hallmark and entree control mechanisms need to be placed in the WLAN.EavesdroppingThis involves attack against the confidentiality of the information that is being transmitted across the web. By their nature, radio LANs deliberately radiates web traffic into infinite. This makes it impossible to command who can have the signals in any radio LAN installing. In the radio web, eavesdropping by the 3rd parties is the most important menace because the aggressor can stop the transmittal over the air from a distance, off from the premiss of the company.3.0 Wired Equivalent PrivacyWired Equivalent Privacy ( WEP ) is a standard encoding for radio networking. It is a user hallmark and informations encoding system from IEEE 802.11 used to get the better of the security menaces. Basically, WEP provides security to WLAN by coding the information transmitted over the air, so that merely the receiving systems who have the right encoding key can decode the information. The undermentioned subdivision explains the proficient functionality of WEP as the chief security protocol for WLAN.3.1 How WEP Works?When deploying WLAN, it is of import to understand the ability of WEP to better security. This subdivision describes how WEP maps accomplish the degree of privateness as in a wired LAN [ 16 ] . WEP uses a pre-established shared secret key called the base key, the RC4 encoding algorithm and the CRC-32 ( Cyclic Redundancy Code ) checksum algorithm as its basic edifice blocks. WEP supports up to four different base keys, identified by KeyIDs 0 thorough 3. Each of these basal keys is a group key called a default key, intending that the base keys are shared among all the members of a peculiar radio web. Some executions besides support a set of unidentified per-link keys called key-mapping keys. However, this is less common in first coevals merchandises, because it implies the being of a key.3.2 Failings of WEPWEP has undergone much examination and unfavorable judgment that it may be compromised. What makes WEP vulnerable? The major WEP defects can be summarized into three classs [ 17 ] :3.2.1 No counterfeit protectionThere is no counterfeit protection provided by WEP. Even without cognizing the encoding key, an antagonist can alter 802.11 packages in arbitrary, undetectable ways , deliver informations to unauthorised parties, and masquerade as an authorised user. Even worse, an antagonist can besides larn more about the encoding key with counterfeit onslaughts than with strictly inactive onslaughts.3.2.2 No protection against rematchsWEP does non offer any protection once more rematchs. An adversary can make counterfeits without altering any informations in an bing package, merely by entering WEP packages and so retransmitting later. Replay, a particular type of counterfeit onslaught, can be used to deduce information about the encoding key and the informations it protects.3.2.3 Recycling low-level formatting vectorsBy recycling low-level formatting vectors, WEP enables an aggressor to decode the encrypted information without the demand to larn the encoding key or even fall backing to hi-tech techniques. While frequently dismissed as excessively slow, a patient aggressor can compromise the encoding of an full web after merely a few hours of informations agg regation.4.0 Practical Solutions for Procuring WLANDespite the hazards and exposures associated with radio networking, there are surely fortunes that demand their use. Even with the WEP defects, it is still possible for users to procure their WLAN to an acceptable degree. This could be done by implementing the undermentioned actions to minimise onslaughts into the chief webs [ 5 ] :4.1 Changing Default SSIDService Set Identifier ( SSID ) is a alone identifier attached to the heading of packages sent over a WLAN that acts as a watchword when a nomadic device attempts to link to a peculiar WLAN. The SSID differentiates one Wireless local area network from another, so all entree points and all devices trying to link to a specific WLAN must utilize the same SSID. In fact, it is the lone security mechanism that the entree point requires to enable association in the absence of triping optional security characteristics. Not altering the default SSID is one of the most common security error s made by WLAN decision makers. This is tantamount to go forthing a default watchword in topographic point.EAPThe Extensile Authentication Protocol ( EAP ) is a general hallmark protocol defined in IETF ( Internet Engineering Task Force ) criterions. It was originally developed for usage with PPP. It is an hallmark protocol that provides a generalised model for several hallmark mechanisms [ 15 ] . These include Kerberos, public key, smart cards and erstwhile watchwords. With a standardised EAP, interoperability and compatibility across hallmark methods become simpler. For illustration, when user dials a distant entree waiter ( RAS ) and utilize EAP as portion of the PPP connexion, the RAS does non necessitate to cognize any of the inside informations about the hallmark system. Merely the user and the hallmark server have to be coordinated. By back uping EAP hallmark, RAS waiter does non actively take part in the hallmark duologue. Alternatively, RAS merely re-packages EAP packages t o manus off to a RADIUS waiter to do the existent hallmark determinationWI-FI PROTECTED ACCESS ( WPA )The WPA can be expressed as: 802.1x Authentication + TKIP + ( optional ) AES. 802.1x Authentication WPA relies on the 802.1x hallmark described in the old subdivision for authenticating wireless clients via a RADIUS waiter and bring forthing the secret keys which are so used to make encoding keys. This implies that 802.1x must utilize an hallmark method ensuing in the secret key coevals ( such as EAP-TLS or EAPTTLS ) . Because shared secret keys, generated as the consequence of 802.1x hallmark are alone for each client, WPA-enabled APs will manage multiple keys. To do WPA useable by little concerns and place offices, which do non hold RADIUS-based hallmark environment, 802.1x hallmark may be replaced with the shared key hallmark which resembles WEP hallmark. This manner of WPA hallmark is known as Pre-Shared Key ( PSK ) manner ( vs. Enterprise Mode used with the 802.1x hallmark ) [ 22 ] .TKIPTKIP ( Temporal Key Integrity Protocol ) is responsible for bring forthing the encoding key, coding the message and verifying its unity. Although the existent encoding is performed utilizing the same RC4 Cipher algorithm as WEP, specific sweetenings are added to make stronger encoding key and guarantee that italterations with everypacketis alone for every clientA cryptanalytic message unity codification, or MIC, called Michael, to get the better of counterfeits.A new IV sequencing subject, to take rematch onslaughts from the aggressor? s armory.A per-packet key blending map, to de-correlate the public IVs from weak keys.A re-keying mechanism, to supply f resh encoding and unity keys, undoing the menace of onslaughts stemming from cardinal reuse.Encrypted Tunnel or VirtualPrivate Network ( VPN )Packages are unbroken private by the usage of encryption.Encryption systems are designed to supply avirtual tunnel that the information base on ballss through as it traverses the protected portion of the network.If the system is decently designed and correctlyimplemented, the contents of the warhead will be indecipherable to those without the proper decoding key. The contents that the receiving system decrypts must non merely be private, but precisely as the senderintended. In other words correct tunnel will notonly maintain the contesnts private, but besides free from alteration. This requires the usage of acryptographic unity checker or checksum.Tunneled Transport Layer Security( TTLS )It is non clear whether or non EAP-TLS can be implemented without a public key substructure for certificate exchange. We believe that it ispossible to put in the certifications on the client andserver without utilizing a PKI but we are non perfectly certain that this is the instance. But there isno uncertainty that TTLS does non necessitate a PKI.TTLS differs from EAP-TLS in that it is a two phase protocol. In the first phase an encrypted tunnel is established between the client and waiter. In making so, the waiter presents itscertificate to the client and therefore the client is confident of the waiter? s individuality. In the 2nd stage the client? s certificates are given to thefor proof. These certificates are in theform of attribute-value braces and non digital certifications. [ Gas02 ] All EAP hallmark protocols run into this standard. Because the certificates are passed in an encrypted tunnel a digital certification is non necessary.Protected ExtensileAuthentication Protocol ( PEAP )PEAP is really similar to TTLS. It is truly merely a different spirit of TTLS. It is besides a two stage protocol. The first stage is used to authentic atethe waiter and set up an encrypted tunnel between the client and the waiter. Then alternatively ofusing the older attribute-value brace to authenticate the client, hallmark is limited to any EAP method. Since EAP includes a broad array of hallmark protocols this is non a terrible limitation, but it does let less flexibleness than TTLS. [ Gas02 ]

Ellington and Jazz in the 30s essays

Ellington and Jazz in the 30's essays Duke Ellington and the Harlem Renaissance: The term Harlem Renaissance refers to an artistic, cultural, and social time of writing about race and the African American's place in American life during the early 1920's and 1930's. It is hard to put a specific time and date in terms of social criticism, protest and political advancements, because of the fact that it took a long time for it all to develop. Overall, the Harlem Renaissance was a time of African American's expressing talent and ideas, and was the center of urban black life in America. All oppressed African American's knew that if they wanted to express themselves, they would go to Harlem. Harlem was your best chance at changing your life. Harlem was considered the heart of the Renaissance in African American letters, creating the name The Harlem Renaissance. Harlem was the center of African American life. Most black literature of the time referred to Harlem as Home. Harlem stands as a symbol for the best and worst qualities of African American life during the early twentieth century. The Harlem Renaissance was a time where blacks would show their true identities, emotions, feelings, opinions, etc. Blacks expressed themselves socially, culturally, and through various forms of arts, such as paintings, literature and music. The main music of the time was Jazz. Jazz music began sometime around 1895 in New Orleans. It combined the elements of Ragtime, marching band music, and Blues. The main difference between Jazz and these other types of music was the widespread use of improvisation, often played by more than one player at a time. Jazz represented a break from Western musical traditions, where the composer wrote a piece of music on paper and the musicians then tried their best to play exactly what was in the score. In a Jazz piece, the song is often just a starting point or frame of reference for the musicians to improvise around. The song m...

Application of Revenue Management Practice in the Hotel Industry Essay

Application of Revenue Management Practice in the Hotel Industry - Essay Example Modern hotel revenue management brand varies extensively from that of more than two decades ago. Modification in the general handling of revenue management, inventory allocation, pricing strategy, use of information and channel management as concerns to revenue management tend to redefine the field. Similarly to how detailed past analysis might have a representation of the best pricing practice during the 1990s, apparently, the stock market-impacted algorithms exist in the cutting edge of modern pricing thought. Comparably, the highlighting on occupancy or average day to day rate, which might have dominion over revenue managers’ outlook over two decades ago has led to the dominance of revenue per available room i.e. RevPAR. Instances like this abound hence this article will endeavor to share all of the revenue management expertise with readers, in a series examining the modern revenue management’s best practices (Kimberley, Trevor & Juston 2008, p.12). Strategic Pricing Pricing tends to a feature of revenue management, which features a number of intriguing, as well as innovative developments recently. Whereas pricing has continued to be a significant driver having an effect on both occupancy, along with RevPAR, in the present environment surrounded by exceptional price transparency, rates have taken an even bigger role. Ascertaining the optimal rate to give to a potential customer tends to be one of the most significant concepts of revenue management. The basic fact that the appropriate rate- one that achieves the balance between replicating enough demand in maximizing occupancy, while at the same time, not deserting money on the table within the form of low down ADR turns out to be the key to a profitable revenue management strategy causing pricing perhaps the most significant concept of revenue management. Then how is a hotel capable of determining what the best rate has to be anytime? In the past, this would center on historical analysis, while , at the same time, computed by the application of a discount to a fixed rack rate. In this case, there is no achievement of the objectives of revenue management, and in a modern environment, they are incapable of providing a competitive advantage that is adequate; therefore, the best revenue managers, as well as revenue management systems are dependent on the stock market principles in the formulation of complex algorithms, which are capable of generating with exactness of the optimal rate. Apart from that, these systems tend to work perfectly in real time, thereby making subtle modifications at brief gaps of time in the maintenance of the best rate. Therefore, in this case, the two most excellent practices at work tend to be automation, as well as an advanced algorithmic tactic of pricing (Roy & Bob 2008, p.31). The Stock Market Pricing The rule of optimum pricing happens to be familiar to financial experts, especially those working with commodities. In the case of hotels, it turn s out to be a less familiar concept, yet there is no reason as to why this should be the case. High-performing hotels use a comprehensive system of revenue management, which sets prices on the basis of both historical considerations, as well as current market conditions, providing it twice the choice of pricing strategies that are more traditional. Subsequently, these systems happen to be a reflection of similar systems within the place at financial companies.  

Two questions related to Public Budget and Finance Essay

Two questions related to Public Budget and Finance - Essay Example Public budgeting is targeted towards the wellness of citizens. A little wrong prioritization, misallocation of resources, and financial negligence in this process can pose certain challenges for the government regarding implementation of public wellness programs and other public policies. Public budgeting holds a critical place in decision making processes because it is directly associated with the well-being of citizens. It is one of the main responsibilities of any government to allocate resources among competing public sector needs in such a way that none of the sectors faces shortage of funds in any particular stage. Public budgeting includes analysis of the needs of all public sectors and allocation of financial resources in accordance with the analysis report. It is obvious that if one program is overfunded, some other public service program will definitely bear the costs. It is the job the government to decide which sector should be given more space in the public budget and wh ich sector should be at stake. Given the nature of the public budgeting process, governments usually encounter difficulty in making decisions regarding starting of new programs and eliminating existing programs. They have to decide on these issue based on financial analysis of the current economic position of the country. In America, it is the responsibility of executives, legislators, as well as judiciary to maintain a check and balance on the public budgeting process. In the Federal government system, the congress enacts the budgets, whereas the president is held responsible for providing the guidelines for the preparation and submission of the budget. Public budgeting provides government officials the information about current financial position of the economy by detailing the capital in hand, as well as predicted future expenditures related to current and ongoing business processes. Proper financial analysis also helps governments cut off the extra costs and utilize the availabl e capital for other public service activities. Governments need to plan business and public wellness activities according to their financial budgets. If a government does not pay attention towards managing financial activities, problems can occur which may delay the planned activities (Lynch, 1991). Therefore, from public budgeting perspective, it is imperative to develop a perfect budget plan that should help the government in achieving the desired goals and objectives while maintaining the financial equilibrium. Having discussed the public budgeting system in detail, let us also talk about information, justification, and examination that play an important role in the development of a public budget. Budgeting is primarily based on information. Budgeting systems are all about gathering reliable and accurate information of both technical and political nature and using that information in making resource allocation decisions. Justification refers to process of deciding whether a publi c service program should be funded or not based on proper justifications. Examination, on the other hand, is all about analyzing the way organization’s resources have been used in the past and developing a course of action for future programs. Answer No. 2 Budget Process As Morgan (2006) states, â€Å"the success of a business depends on the capital budgeting decisions taken by the management† (p. 1). Budgets are prepared to set and accomplish organizational goals and objectives. These budgets help the organizations in preparing a
