In pulling manufacturing and design en travel guidebook for computerization, the inclination is to provide as much power as probable to the mechanism and leave the lingering job tasks at hand. This automation viewpoint reduces the data and perceptive capacities of workers and pushes them to dislike the engineering.Premises in the field of tuition system management are significant whether ones orientation is in the precaution of research or practice (Tapscott, 3). The responsibility of an organization is to help out in withdrawing the complication of the world and explaining and predicting proceedings.

Texas Education Essay Example for Free

Texas Education EssayTexas law makers and citizens have been concerned about the education of our unfledged people since before declaring our Independence from Mexico in 1836. Texas revolutionaries listed failure to establish any general arranging of education, although possession of almost boundless resources, among the reasons to become independent from Mexico. Since that cartridge clip public education has seen countless indemnity changes, constitutional amendments and revisions, and laws changed to chance upon the needs of Texas students. (1) How has the Texas education governing body changed?How have these policies affected our preteen people, and what ch whollyenges lay ahead for students, educators, p arnts, and policy makers? At the birth of Texas public education there were many problems that policy makers had to overcome. How to educate students in such rural atomic number 18as? How forget public education be inventoryed? These were a few of the scraps that lawmakers of that time faced but one challenge they didnt not have land as one of them. The first public work law was written setting aside large amounts of land in each county for public school use.Later the amount was increased and superfluous land was set aside for the first State College. However what Texas lacked was support. (2) In 1845 Texas received 10 million in five percent U. S. Indemnity bonds for remission a boundary claim against the United States. Of this 10 million, 2 million was set aside as a permanent school fund. The permanent school fund was later directed to be invested in bonds. Also, during 1845 the state constitution set aside one-tenth of the annual state tax set aside to support free public schools.(1) The founding fathers of Texas public education were working toward the goal of adequately funding the Texas education system. Today the permanent school fund accounts for approximately $765 million a year. (1) A extendd effort has withal been made th rough the life of Texas public education to excogitate a system of accountability. 1885 marked the first year a system of accreditation was used for Texas public schools. At that time selected tests were sent to the University of Texas. If the school was found to be satisfactory students gained machinelike admission without examination.(1) Although the intent was Texas public education had many problems. One was the growing concern for the decline of Texas literacy. Legislatures tried to address this issue in 1984 when Texas passed House snout 72. The 68th Legislature passed this bill in response to concerns over the adequacy of Texas public schools as reflected by standardized tests. (2) House Bill 72 brought down tougher requirements on students and began rating the schools in 1993. The students were now required to pass a state assessment test in order to meet the graduation requirements.This was system of examination was the most difficult students had been exposed to up unti l this point. Also the Bill created the no pass no play rule that requires students to pass every subject in order to participate in any extracurricular activity. (2) An new(prenominal) problem that the Legislature attempted to address was funneling funding to property poor districts. Edgewood ISD v Kirby was filed and claimed that the system for funding public schools was discriminatory against poor districts. Edgewood ISD was against House Bill 72 and wanted a fair system of school funding.The courts ruled in estimation of Edgewood ISD but law makers continued to try and come up with a fair system. The federal government threatened to shut down federal charge for public schools because of non-compliance. In 1990 Legislature tried to pass the Robin Hood plan. This plan would redistribute wealth from wealthy districts to poor districts. This Bill failed to pass voters. In 1993 another plan was passed by the State. This gave multiple options to districts to distribute funds equally . (3) Edgewood ISD v Kirby was not the first lawsuit filed in an effort to improve Texas public schools.Del Rio ISD v Salvatierra tried to show how inferior education facilities were for Mexican-Americans and moved toward desegregation. In 1948 Delgado v Bastrop ISD, the judge ruled against segregation of Mexican-American children in public schools. Sweatt v Painter in 1950, challenged separate but equal and consolidation was ultimately addressed with a federal ruling in 1954with Brown v Board of Education and the integration of Mexican-Americans in 1970 with Cisneros v Corpus Christi. In that like year because of discriminatory practices in Texas schools, United States v Texas forced a federal judge to foreshadow for all schools to be integrated.(3) Texas is unique in many ways from other states. Texas is second among size and population and educates 9% of the total U. S. student population. A passing divers(a) student population creates additive problems. 16% of the student population in 2007 was Limited English in effect(p). IN that kindred year 55. 5% of all students were recognized as economically disadvantaged. In 2007 those two categories ranked the lowest among percentage of students that passed all beas of the State assessment test. With 47% of Limited English Proficient passing all categories and 57% of economically disadvantaged passing all categories.Texas also ranks 15th in the nation with 8th grade students in mathematics, thirty-first in reading, and 35th in science. All this unique situation occurs while ranking 49th among funding per student as comp bed to other states. (4) These statistics put Texas in a unique situation. Texans are educating more people and more of those people are in greater need of a quality education. How can Texas children compete in the job market? What will the Texas workforce look like for these children? Concerns continue to grow over declining school performance and budget deficits.The budget shortfalls w ill mean education spending cuts. Texas is a conservative state. Its legislatures take great pride in balancing the state budget with responsible spending. Many time these cuts are made in the name of the children in an attempt to not pass down large amounts of debt. To continue to cut an education system that is at the bottom on spending per student will only push Texans further below the national average of graduation rates. Texas education continues to beneathperform. (5) practice of law makers continue to decrease funding in schools and will not increase taxes to attempt to meet the budget shortfalls.Texas boosts rapid business growth and population growth. They attribute often of this growth to a tax kindly environs for the top 60% income brackets and affordable living for all income brackets. This has made us a national draw among growth and is a source of pride among lawmakers and Texans. (6) Law makers attempted to help the education crisis in Texas during the 83rd le gislative session. The passed over 100 laws affecting education. These rules ranged from bonds for charter schools, muscular eating statutes in schools, law enforcement on campuses, testing and ratings of districts, and school financing.Many laws were made mandating that schools have to perform at a higher level and also that schools have to help produce healthy students while also protecting them. All these programs take more money yet the Texas budget does not tolerate for additional funds. The state legislatures say that if these schools cannot perform they should be shut down. What options would that leave Texas students and their families? (6) More than 150,000 Texas students are choosing public charter schools over traditional public schools. open charter schools receive bonds and funding from both the state and federal government similar to traditional public schools.They boost a higher learning environment while managing to do it on a smaller budget than traditional publi c schools. They are held to the same Texas accountability systems but have the freedom to develop their own course of study where as a traditional public school is held to the state curriculum. The Texas Board of Education approves the curriculum that public schools can use. They develop the curriculum and the district has the freedom to determine how they will teach this to their students. They can use many different programs from traditional text books to the unpopular c-scope curriculum.Charter schools on the other hand are allowed the freedom to teach how they want to teach and what they want to teach as long as they perform well on the same state assessment tests that public schools must take. (7) Charter schools are an alternative that many Texas parents and students are electing for. The freedom they are allowed are creating a learning friendly environment while providing teachers the freedom to teach. Students are able to learn and teachers are able to teach. All under the same budget constraints that traditional public schools have.not having to teach to a particular curriculum is favorable for some parents that may not want a conservative influence on their students. For example the new-made conservative wins over social studies curriculum. Conservatives won to modify social studies texts to look favorably on Republican political philosophies and stressing the superiority of American capitalism. The fight continues are could be won in the near future for the removal of the teachings of Darwinism and to move toward the inclusion of the Christian views that founded our nation.The charter schools will not be held to these same teachings and are free to teach the religious side, conservative side, liberal, and science. Many parents find this form of teaching more favorable and the freedom it provides help to responsibly teach Texas students under the budget constraints that the state mandates. (8) Not all academic changes are viewed as bad. Republican s pushed for information about the violent nature of the Black Panther party is taught in contrast to the teachings of Dr. Martin Luther King, and that the Republican votes are included in teaching to show how Republicans pushed forward on civil rights issues.Some strides were made in the inclusion of in the flesh(predicate) responsibility teaching to students, which includes life choices such as suicide, pregnancy, dating violence, eating disorders and drug disorders. Some people such as Mavis Knight, a populist from Dallas that introduced an amendment for the teachings of the founding fathers on religious freedoms but it was turned down, said the social conservatives have perverted accurate history to fulfill their own agendas. (8) If you were a young adult or adult in the 90s you was also part of legislative of an advertising campaign to pass the lottery in Texas.A large part of this campaign was that that the majority of the lottery proceeds would go toward Texas education. Ma ny Texans often wonder how we can need to cut school funding when 21 billion dollars has been contributed through the Texas lottery system. This was true and false all at the same time. 21 billion has been contributed to Texas education. The majority of the proceeds from the Texas lottery are going into the Texas Education fund but the false is that for every dollar contributed by the lottery the general fund decreases its contribution.So funding remains the same just the contributing party changes. This was a rouse by legislatures at the time and continues to be. (9) Another large source of school funding is property tax. Law makers have continued to address the disparities between district funding in regards to property tax revenue. Property within districts can vary greatly. Some districts may be comprised of multi-million dollar homes while other modest middle class homes and even others that are made up of very poor communities.These differences in tax revenue base have created large differences in the quality of education provided for Texas students. Lawmakers have attempted to address this with bonds and funding per pupil but any Texas resident physician that has visited an inner-city school and visited a school in affluent Plano or wealthy areas of the valley know that there are great differences in the amenities provided to students in those districts. (10) Another challenge Texas faces is staffing its schools with quality educators. There is a shortage of educators in Texas.After the 2011 much publicized decrease in the teaching population and additional constraints on class size. The perception of an already stressful and underpaid profession was damaged. In 2012 the number of teaching certificates acquired was down 24 percent. Projections show that Texans will not meet the number of needed teachers by 2015 if the issue is not addressed. The Texas Workforce Commission predicts that the need for teachers will greatly increase and is the highest proj ected are of growth in Texas.The challenge comes in attempted to convince young adults to invest their education dollars in this field. (11) There are many challenges that face Texas educators. How can Texas educators teach to the diverse student population accurately with the other challenges that face the public education system? According to the Kids Count Data Center, Texas has a student population of 16. 2% that receive ESL teaching. These present additional challenges for teachers. Texas was an early pioneer for English as Second Language training.In 1968 lawmakers pioneered for English deficient students by allowing ESL programs in Texas Schools. Up until that time it was not allowed to have bilingual programs in the schools. Then in 1981 further strides were made when Mexicans Americans were allowed to enter those programs voluntarily to help eliminate discrimination of Mexican American students. Today Mexican American students account for 50. 2% of the student population an d although this poses additional challenges Texas must be prepared to meet those challenges. (10) There are so many challenges facing Texas education.A diverse student population, proper funding, legislatures with personal agendas, increase academic standards, meeting demands of the workforce from laborer to laboratory, all these are achievable. These challenges can be met by Texas parents, legislatures and students. At an early age Texas students are taught how great and unique Texas is and its residents and how we are have risen to many challenges and defeated them. The challenge of education will be gladly met and I feel confident that Texans will see the importance of education and do everything necessary to ensure that Texas younker are able to compete in todays job market.

Diet and Digestion as Factors for Large Size in Sauropods

Diet and Digestion as Factors for Large Size in SauropodsDinosaurs acquire captured the imagination since the very first fogeys were discovered. The mystical creatures in many ancient cultures may be attributed to fossils weathering out of the earth. Nearly every culture had almost form of dragon in their mythology, a uniformity best explained by fossilized dinosaurs. Some scientists believe the fossils of c date of referencetopsians ar the source of the mythological griffin. Part of the fascination with dinosaurs is their size. With few animals reaching such bundleive proportions, the creatures that produced single cram as tall as a human must bugger off seemed other worldly to ancient peoples. They still kowtow fascination today their features so different from anything living. As more and more fossils are found, explanations and extrapolations of the features, size, and behavior become more comprehensive. The unknown element of dinosaur life earmarks for nuts projectio ns and suppositions, and the drama of discovery and scientific discourse and hypothesis disproval continue to draw the interest of people. As more is discovered, more suspenses are raised. One field of questions mention to sauropod size. Sauropods are distinct in their absolutely cudive bodies. Far braggyr than anything known by living humans, they are fascinating to consider. Trying to cypher their size is in round ways like trying to imagine the vastness of space. Without actually standing next to a mounted skeleton, there is no living reference to fix the size of sauropods in the imagination. Some estimates place the colossalst sauropods at 80,000kg, or 170,000 lbs. Conservative estimates suggest weights of 40,000-50,000 kg. Sauropod height is in some specimens 60 feet, about 3 times the height of a two-story house. Some sauropods were a third of a football field in length such sizes are nearly unfathomable, raising the question of how they got to be so massive and how th eir bodies functioned. Modern herbivores are often much bigger than carnivores, because in general, their energy expenditure is less and the biomass of their food source is higher(prenominal). The huge size of sauropods is definitely tied to their diet, and it is in all probability that their food source and digestive mechanisms were a major factor in their emergence to such massive sizes.The food available to sauropods was not very nutritive. Before the evolution and diversification of angiosperms 125 one thousand thousand years ago, anthophagous animals had to rely mainly on gymnosperms and ferns. The best measure of flora nutritional value is in the concentration of north and nonstructural carbohydrates like sugars. Protein levels macroscopicly correspond to the nitrogen levels in emerges. Because non-angiosperm plants dont have the xylem transport network that evolved, there is less nutrient flow, and therefore less nitrogen concentration. Ferns, cycads, and conifers, s ome of the main plant types available to the sauropod dinosaurs, were low in nutrition, and gymnosperms had secondary chemical defenses that made them unpleasant to eat and harder to digest (Midgley, 2005). A study by Zvereva and Kozlov (2006) found that the nitrogen concentration in gymnosperms drops in environments with elevated temperature and CO2 concentration, compared to the modern environment. Sugar levels tended to stay the same. The toughness of leaves increases when CO2 levels are higher. The carbon-nitrogen ratio is significantly increased by elevated CO2. It is well-known(a) that the environmental conditions during the age of dinosaurs was two higher in temperature and higher in CO2 concentration. This would have produced plant material significantly less nutritious than the plant matter today. The lesser food character supports the evolution of prominent sauropod dinosaurs, as the Jarman-Bell Principle states that large species can feed on diets of lesser quality f ood, evidenced by the relatively large size of modern grazing mammals (Clauss, et. al., 2009). The physiology of the dinosaurs shows evidence of partitioning. Some sauropods, such as diplodocids, were low browsers, who were un believably to life their heads higher than a couple meters (Stevens and Parrish, 1999). This separated their food source from the mid to high browsers, limiting their available food source in some ways, yet in any case preventing competition amongst sauropod species. The dispirit plant quality requires that herbivorous animals consume more material in order to meet their nutritional and energy needfully. presumptuousness the quality of available plants, extended digestion would have been required. Of several methods to process plant material, sauropods digestion was extremely fermentation heavy. They had very little ad-lib processing. Their teeth were either handsome and leaf like, with serrations in the crown, or later more narrow and peg like. In most s auropods, teeth were present in the front part of the embouchure but not the jeopardize. The body plan in the early Mesozoic seems to have been to maximize food intake through teeth adapted for cropping, stripping, and twist plant material but with little oral processing. on that point is some evidence in the tooth replacement rate and wear that teeth farther back in the blab outs of sauropods were not used in oral processing or food acquisition, but rather served the purpose of cheeks, to keep the food in the mouth (Schwarz, et. al., 2015). Prosauropods had some check development, but in the sauropod line, cheeks were lost early (Chure, et. al., 2010). There have been no teeth found in association with sauropods that had a large horizontal surface, indicative of use for chewing (Christiansen, 1999). The heads of sauropods were extremely small compared to their body size. Any dental batteries or cheeks would have increased the head mass and likely made it prohibitively heavy, e particular(a)ly at the end of a pine neck. Christiansen likewise noted that the muzzle width in sauropod dinosaurs is proportionately wider than the width in herbivorous animals. This enables sauropods to intake more food per bite, increasing their intake rate. With relatively poor food nutrient quality, sauropods would need to consume a great amount of food to meet their daily needs. The length of the neck adds length to the digestive envelope, another way to maximize food consumption. The lack of oral processing, wide muzzle, and long neck work in conjunction to increase the consumption cap cogency or sauropods, increasing their ability to meet their dietary needs and shortening their feeding time.With such high consumption and such little processing, digestion would be almost entirely focused in the gut. The particle size would be very large, making digesta harder to break down, and the longer it takes to digest. There has been some debate about the mien of gastroliths and a gastric mill in sauropod dinosaurs. stomachic mills certainly would help break down the plant material into smaller particle sizes and speed the digestion process. Unfortunately, the fossil record seems to rule out the presence of a gastric mill for most sauropod dinosaurs. Wings and Sander (2007) tested the hypothesis of sauropod gastroliths by testing gastrolith usage in acquire ostriches. They found that rose quartz, which has the same properties as the white vein quartz found in association with sauropods, last the longest. Using granite cubes, they found that the general imprint of the stone stays the same. They also found that the gastric milling process quickly roughens the face of the stone. None of the stones that he used in his test hold a shine, unlike those suspected to be sauropod gastroliths. He also found that gastroliths are about 1% of the total body mass. According to them, the largest mass of gastroliths found in association with a sauropod is 15kg, much lowe r than 1% of the estimated sauropod body mass. Gastroliths likely scale with body mass exclusively because organ size roughly scales with body mass. The stomachs of sauropods could have been proportionally smaller than expected, although it is unlikely with the amount of food that they are estimated to have consumed. Using projections from living herbivores, it is estimated that the large sauropods would consume several hundred kilograms worth of food (Englemann, et. al., 2004). This estimate accounts for the proportional decrease in required food consumption for successively larger and larger organisms. In another study focusing on the distribution of gastrolith stones amongst sauropod remains, it was found that gastroliths were found with about 4% of sauropod fossils. There are some species of sauropod that have strong evidence of gastric mills, but they are not widespread enough (Wings, 2014). With little to no processing of plant material, and with no evidence of any other brea k down processes, sauropods must have heavily relied on fermentation to digest their food. The relatively low density of nutrients in the gymnosperms at the time already required longer fermentation times. In order to achieve longer fermentation time, the gut size needs to increase, or the amount of food eaten needs to decrease. As the food particles must have been large, the time taken for fermentation would need to be even longer. With no inherent soft tissues preserved in the fossil record, it is hard to determine where fermentation took place in the gut. Fermentation demands a large digestive tract. Larger intestines allow for longer digesta property, pulling more nutrients from the food. The large torsos of sauropods could certainly fit and extensive gut. Estimates based on living animals gives a digesta retention time between 8 and 16 days. Galapagos turtles, which do not chew their food, retain theirs for 11 days (Franz, et. al., 2009). Sauropod dinosaurs could have evolved to be so large because those individuals with larger guts had break-dance survival chances than those who had smaller guts. As stated previously, the amount of food needed in relation to the body mass would likely have been much lower than other, smaller herbivorous organisms. As sauropods heads were evolved to take in the maximum amount of food, the intake of food would likely not have consumed most of the sauropods time. This time profit would have been especially needed in semiarid environments, like the Jurassic area preserved in the Morrison formation. Although there is lush vegetation in the Morrison fossil record, it is not widespread instead found in clusters. The Morrison fundamental law suggests that the environment during the time of sauropods was savannah-like. The dense vegetation found was likely due to seasonal rains, or centered around areas of water, such as lakes or streams. The vegetation likely moved, growing in different areas depending on rainfall (Englemann , et. al., 2004). Large herbivores would need to attach to the seasonal changes, and migrate in search of new food sources. The size of the sauropods and the advantages of that size would have been a major edge in a semi-arid environment. much(prenominal) sizes would have also made locomotion more efficient. Longer strides afforded by the overall large body size decreases the amount of energy per unit of distance. This, too, increases the ability of sauropods to migrate in search of food. Sauropod reliance on fermentation was so great that their methane production has been linked to the warm climate of the Mesozoic era (Wilkinson, et. al., 2012). Assuming a more reptilian metabolism, one paper puts the global biomass of large sauropods at 200,000 kg/km2. Their total estimated annual methane emission is about 520 million haemorrhoid. For comparison, modern day ruminants produce about 50-100 million tons of atmospheric methane, and the total modern day global emissions are about 50 0-600 million tons a year. The author notes that their estimate could have been overstated by a factor of two, but also understated by the same amount, depending on fictive metabolic function and density of sauropods. Sauropods large sizes and reliance on fermentation to digest food was a major influence on their environment, and created a supportive feedback loop, where the temperature increase would push nutritive values of plants lower. Massive sauropod bodies were well adapted to their environment and digestion.Of course, such large sizes bring their own challenges. The most debated question is whether or not dinosaurs were endothermic or ectothermic, and whether endothermy was even possible in mega dinosaurs like the sauropods. At body masses estimated between 20,000 kg and 80,000 kg, overheating would have been a huge problem in large sauropod dinosaurs. While it is unknown if they had special soft tissue adaptations in order to combat their size, it is speculated that their long necks and tails may have helped them keep cool by increasing surface area without adding too much internal volume ( bird of Jove, et. al., 2011). The accelerated growth capable in endothermic animals is a major factor in favor of sauropod endothermy. Sauropods grew several size magnitudes, from hatchlings estimated to be about 10kg, to the hulking full-grown dinosaurs, in only a few decades (Sander Clauss, 2008). But does the size of adult sauropods rule out endothermic metabolisms? According to Eagle and others (2011), endothermy was not impossible in large sauropods. In lower temperatures, more 13C-18O clumps form, which are preserved in the fossil record. The analysis of these clumps is not dependent on knowing the oxygen isotope news report of the surrounding water. These clumps can be observed in the tooth bioapatite of dinosaurs. The accuracy of this method is 1C, with precision within 1-2C. The accuracy of this method comes from tests of modern taxa, in which the iso topic temperature agrees with the expected temperature of the organisms. Eagle found the average body temperature of Brachiosaurus to be 38.2C 1C and the temperature of Camarasaurus to be 35.7C 1.3C including a prototype from a different fossil site. These temperatures are within the range of modern mammals, and lower than the body temperatures of many birds, which can be greater than 40C. Eagle does note that the temperature reflects the temperature of tooth formation, which may differ from the main body temperature. Body temperature is a product of metabolism, size, environmental temperature, and any special adaptations for the regulation of heat. The temperatures given for these sauropods is close to the temperatures estimated by earlier research done by Gillooly (2006). Such temperatures in such large animals suggests that they were either ectothermic, had low basal metabolic rates, or had some special methods of heat dissipation. Some researchers suggest that large sauropods were fermentative endotherms (Mackie, 2002). Because sauropods needed a lot of energy to reach their adult size in such little time, it is likely that they were endotherms who underwent some sort of change at maturation that prevented overheating as an adult. Metabolic changes through development is not unusual, so it is very possible that it also occurred in sauropods. They could have shifted from a higher metabolic endothermy during their rapid growth phase, to a lesser metabolic homeothermy supported by the fermentation heat turnout from their fully formed guts. Other evidence in support of endothermic sauropods are growth lines, or the lack there of, in sauropod bones (Kohler, et. al., 2012). Lines of arrested growth are normally associated with ectotherms, which have periods of rapid growth interspersed with periods of slow growth. These lines are found in mammals as well, and in the majority of dinosaurs. The pattern the lines leave are not found in sauropod bones. This sugge sts unbroken, stead growth rates, highly unlikely in ectotherms. The evidence suggests endothermy in sauropods, even in large ones. Because endothermy requires more energy to maintain, sauropods would have had to consume a massive amount of food, unless they had a low basal metabolism. Hippopotami, while mammals and clearly not the size of sauropods, have particularly long retention times because they have low food intake and enormous gut capacity. Their required energy for maintenance is remarkably low. This scheme is common in non-ruminant foregut fermentators and some small hindgut fermentators (Clauss, et. al., 2009). The metabolic process of sauropods is linked to their energetic needs and dietary restrictions. In some research, one of the byproducts of fermentation, heat, supports the endothermic theory, and endothermy in sauropods as juveniles helps explain how they managed to reach their massive adult size. The herbivorous, fermentative nature of sauropods is not an obstacl e in understanding their ability to function at such large sizes.Sauropods likely evolved to be large because of the abundance of plant materials, especially after many herbivores died out during both the Permian extinction, but also the Triassic-Jurassic extinction. Their adaptations allowed them to widely diversify and fill the newly opened ecological niches. Some have speculated that their large body size was driven by predation, as larger bodies, especially the size of sauropods, were a natural defense (Sander, et. al., 2011). Given the evidence, it is more likely that immunity to predation was a lucky side effect of size, not the driving factor. It seems more likely that the resource opportunities of plants drove the initial adaptation, especially with the diverse nature of sauropods and their apparent partitioning, than protection.The size of sauropods is inextricably linked to their diet and digestive methods. Much of the discussion of sauropod feeding is based on conjectur e is based on living animals, that are obviously very different from sauropods. As there is are no known records of internal tissues, it is hard to know anything about how sauropods functioned internally beyond comparing them to existing behaviors and traits in todays animals. Even though todays herbivores are different than sauropods, patterns of herbivory are similar in very different taxa. The circumstantial evidence offered by analysis of modern organisms still enables scientists to attempt to fit sauropods within the known herbivorous patterns, with allowances for the unknowns. Perhaps this analysis is just another element of the imaginative aspect of dinosaur life. Until more evidence is found, I believe that the evolution of the massive sauropods was in large part due to their diet and digestion. The nutrition offered by gymnosperms demanded higher levels of processing. The minimal oral digestion evidenced by small heads and non-chewing teeth led to greater digesta retention times in the gut. A greater gut size would have sped fermentation, compensating for the large particle size of the plant material and its low nutrient density. There is some evidence for resource partition amongst sauropods, both between different species and within the same species. Different tooth structure and browsing levels are some adaptations driven by available resources. The other benefits of the large body size of sauropods, in my opinion, do not seem likely to be as important in size evolution as the plants and their digestion. When the sauropods appeared, they filled an ecological niche left by previous extinctions, and quickly diversified, creating a hugely successful group of organisms, both in overall diversity, but also in longevity.Works CitedChristiansen, Per, 1999, On the Head Size of Sauropodomorph Dinosaurs Implications for Ecology and Physiology.

A leader must have followers

A leader must have fol natural depressionersIt is a relationship through which one person influences the demeanor or actions of other people. A leader must have followers. Leaders create a vision and then communicate the vision to his followers. Leader energies, revivify and motivate others to translate the vision into achievement. A good leader must have qualities, personality, characteristics or traits. Leadership traits include personal magnetism or personal magnetism (gift from GOD), interpersonal skills, analytical thinking, imagination, decisiveness, trustworthiness, persuasiveness, self motivation, flexibility and vision. There are some styles of leadershipAutocraticThe music director makes entirely the decisions and issues instructions which must be obeyed with reveal question.Advantages bustling decisions can be made when speed is requiredIt is close to efficient type of leadership for highly programmed, routine elaborateDisadvantagesCommunication between the human b eingsager and subordinate leave alone be one way. There may be lack of helpful feedbackIt does not encourage contribution or initiative from subordinates cogentThe manger still makes all the decisions, but explains them to subordinates, and plan of attacks to motivate subordinates to carry them out willingly.AdvantagesSelling decisions to module might make them more willingStaff will have a better idea of what to do when unforeseen events arise in their work, because the manager will have explained his intensions.DisadvantagesSubordinates will not necessarily be committed to decisions in which they have not been involvedThere is no contribution or feedback of subordinatesDemocraticLeader and followers make the decision together, on the basis of consensus, or compromise and agreement.AdvantagesIt can provide high commitment to the decision reachedIt takes advantage of the knowledge and expertise of individuals in contrasting areas, for high quality, bendable decision makingDisad vantagesThe authority of the manager might be underminedDecision making might become a very long process pass along cut decisions might be difficult to reachParticipativeThe manager confers with subordinates and takes their views and feelings into account, but retains the right to make the final decision.AdvantagesEmployees are involved in decisions. This encourages motivation through greater interest and involvement.Employees can contribute knowledge and experience, to help in solving problems related to their work.Disadvantagesit might take longer to reach decisionssubordinates might be limited in their viewpoint on organizational issuesif the manager does not take employees advice, they might perceive the process to be meaninglessP7 explain the different motivational theories and their application within the workplaceMotivationMotivation is the driving force which causes us to achieve goals. Motivation may be rooted in the raw material indispensableness to minimize physical pai n and maximize pleasure, or it may include specific needs such as eating and resting, or a desired object, goal, state of being, ideal, or it may be attributed to less apparent reasons such as altruism, selfishness, morality, or avoiding mortality.F.W. TaylorTaylor made the head start serious attempt to analyze worker motivation in order to advise management on the best ways to increase worker performance or productivity. The techniques he used of establishing an idea or an hypothesis, studying and recording performance at work, altering working methods and re-recording performance are still used in modern industry. This approach has become known as scientific management due to the detailed recording and analysis of turn ups that it involved. His main aim was to reduce the take aim of inefficiency that existed in the US manufacturing industry. The scope for efficiency gains in early twentieth century manufacturing plants was huge. The vast mass of workers were untrained and non -specialized. They were poorly led by supervisors and managers with little or no formal training in dealing with people. There was usually no formal selection or appraisal system of staff and more were recruited on a daily or weekly basis with no security of employment.How to improve productivity (Taylors scientific approach)Select workers to perform a task. go on them performing the task and note the key elements of it.Record the time taken to do each part of the task.Identify the quickest method recorded.Train all workers in this quickest method and do not allow them to make any changes in it.Supervise workers to ensure that this best way is being carried out and to time them to check that the set time is not being exceeded.Pay workers on the basis of results (based on the speculation of economic man)The surmisal of economic man was widely held, and Taylor himself supported this notion. The view was that man was driven or motivated by money alone and the only factor that could stimulate further movement was the chance of earning extra money. He always maintained that workers should be paid a fair days pay for a fair days work and that the amount should be directly linked up to output through a system known as piece rate. This means paying workers a certain amount for each unit produced. To encourage high output a low rate per unit can be set for the first units produced and then high rates become payable if output targets are exceeded.Elton MayoElton Mayo is best known for his Hawthorne Effect conclusions. These were based on a series of experiments he and his team conducted over a five year period at the Hawthorne factory of Western Electric Co. in Chicago. His work was initially based on the assumption that working conditions (lightning, heating, rest periods and so on) had a scientific effect on workers productivity. Experiments were undertaken to establish the optimum working conditions at all. The results strike all observers, as lightning and al l other conditions were changed, both improved and worsened, so productivity rose in all groups including the control group. This forced Mayo to pay thatWorking conditions in themselves were not that important in determining productivity aimsOther motivational factors needed to be investigated further before conclusions could be drawn. incidental experiments were carried out with a group of assembly line workers. Changes to rest periods, payment systems, assembly bench layout and canteen food were made at twelve week intervals. Crucially, before every major change, the researchers discussed the new changes with the work group. At the end of the experiments the working conditions and work hours were returned to how they had been before the start of the trial. Output rose far in a higher place the original level.Maslow hierarchy theoryMaslows hierarchy of needs is a theory in psychology, proposed by Abraham Maslow in 1943. Then in 1954 this theory was fully evince in his book Moti vation and Personality. Maslows hierarchy of needs is often portrayed in the shape of a pyramid, with the largest and most fundamental levels of needs at the bottom, and the need for self-actualization at the top. The most fundamental and basic four layers of the pyramid contain what Maslow called deficiency needs or d-needs esteem , friendship and love, security, and physical needs. With the exception of the most fundamental (physiological) needs, if these deficiency needs are not met, the body gives no physical indication but the individual feels anxious and tense. Maslows theory suggests that the most basic level of needs must be met before the individual will strongly desire (or focus motivation upon) the secondary or higher level needs.Maslows hierarchy of needs, represented as a pyramid with the more basic needs at the bottomThis hierarchy was interpreted by Maslow as followsindividuals needs start on the lowest levelonce one level of need has been satisfied, humans will striv e to achieve the next levelself-actualization or self-fulfillment is not reached by many people but everyone is capable of reaching their potentialonce a need has been satisfied it will no longer motivate individuals to action, thus when material needs have been satisfied the offer of more money will not increase productivityHerzberg and the cardinal factor theoryDespite basing his research on just 200 professionally qualified workers, Herzbergs conclusions and famous two factor theory have had the superior impact on motivational practices since Taylors work almost 60 years earliest. His research was based around questionnaires and interviews with employees with the intension of discoveringthose factors that led to them having very good feelings just about their jobs andthose factors that led to them having very negative feelings about their jobs.His conclusions were thatJob satisfaction resulted from five main factors achievement, recognition for achievement, the work itself, re sponsibility and advancement. He called these factors the motivators. He considered the last triad to be the most significant.Job dissatisfaction resulted from five different factors company policy and administration, supervision, salary, relationships with others and working conditions. He termed these hygiene factors. These were the factors that surround the job itself (extrinsic factors) rather than the work itself (intrinsic factors).Herzberg considered that the hygiene factors had to be addressed by management to prevent dissatisfaction, but even if they were in place they would not, by themselves, create a well-motivated workforce.Vrooms theoryVrooms theory assumes that mien results from conscious choices among alternatives whose purpose it is to maximize pleasure and minimize pain. The key elements to this theory are referred to as Expectancy, Instrumentality, and Valence.The Expectancy Theory of Victor Vroom deals with motivation and management. Vrooms theory assumes that behavior results from conscious choices among alternatives whose purpose it is to maximize pleasure and minimize pain. Together with Edward Lawler and Lyman Porter, Vroom suggested that the relationship between peoples behavior at work and their goals was not as simple as was first imagined by other scientists. Vroom realized that an employees performance is based on individuals factors such as personality, skills, knowledge, experience and abilities. The expectancy theory says that individuals have different sets of goals and can be motivated if they believe thatThere is a positive correlation between efforts and performance,Favorable performance will result in a desirable reward,The reward will satisfy an important need,The desire to satisfy the need is strong enough to make the effort worthwhile.P8 evaluate the relationship between motivation theory and the practice of management.Payment or financial reward systemHourly mesh rateThis is the most commonality way of paying manu al, clerical and non-management workers. An hourly time rate is set for the job perhaps by comparing with other firms or similar jobs and the wage level is determined by multiplying this by the number of hours worked. This total is usually paid weekly.Piece rateA rate is fixed for the production of each unit, and the workers wages therefore depend on the quantity of output produced. The piece rate can be adjusted to reflect the difficulty of the job and the hackneyed time needed to complete it. These issues are determined by work study. The level of the rate can be very important. If set too low it could demotivate the workers but if too high it could reduce the incentives, because workers will be able to meet their target wage level by producing relatively few units. honorariumThis is an annual sum that is usually paid on a monthly basis. It is the most common form of payment for professional, supervisory and management staff. The salary level is fixed each year and it is not de pendent on the number of hours worked (time rate) or the number of units produced (piece rate). The fixing of the salary level for each job is a very important process because it helps to determine the status of that post in the whole organization. Job evaluation techniques may be used to assist in deciding the salary bands and the differences between them. In most organizations, all jobs will be put into one of a number of salary bands and the precise income realize within each band will depend upon experience and progress. It is always possible to gain promotion to another job in a higher salary band. Firms that are interested in creating a single status within their organization are now increasingly putting all staff manual and managerial on to annual salaries to give the benefits of security and status to all employees.Example of salary bandsJob gradeSalary band (per year)regional headsRs.100000 Rs.200000Departmental headsRs.50000 Rs.75000Office managersRs.30000 Rs.40000Se cretariesRs.15000 Rs.25000Junior clerical staffRs.5000 Rs.10000

Cesare Lombroso :: criminology

Cesare Lombroso was an Italian university professor and criminologist, born in Nov. 6, 1835, in Verona, who became worldwide renowned for his studies and theories in the field of characterology, or the relation between intellectual and physical characteristics. Lombroso tried to relate certain(a) physical characteristics, such as jaw size, to criminal psychopathology, or the innate tendency of individuals toward sociopathy and criminal behavior. As such, Lombrosos flak is a direct descendant of phrenology, created by the German physician Franz Joseph Gall in the beginning of the nineteenth century, and closely related to other fields of characterology, such as craniology and physiognomy. His theory has been scientically discredited, but Lombroso had the merit of bringing up the importance of the scientific studies of the criminal mind, a field which became known as criminal anthropology.Lombroso analyse at the universities of Padua, Vienna, and Paris, and was later (1862-1876) a professor of psychiatry at the University of Pavia and of forensic medicine and hygiene (1876), psychiatry (1896) and criminal anthropology (1906) at the University of Turin. He was also the handler of a mental asylum in Pesaro, Italy.Lombrosos main idea was partly inspired by the evolutionary and genetical studies at the end of the nineteenth century, and proposed that certain criminals had physical evidence of an "atavistic" (reappearance of characteristics which were present only in distant ascendants) or hereditary sort, reminiscent of earlier, more primitive stages of human evolution. These anomalies, named as stigmata by Lombroso, could be expressed in terms of abnormal forms or dimensions of the skull and jaw, assymmetries in the face, etc, but also of other parts of the body. These associations were later shown to be highly discrepant or plainly inexistent, and theories based on the environmental causation of criminality became dominant.

Congress And The Presidency Essay -- Political Science

The president is the foreign polity leader for the United States with an important political, troops and economic role in the multitheme arena. If there is collision between the president and congress, can congress restrain the president in foreign constitution making?The era of globalization has witnessed the growing influence of a number of unconventional international actors, from non-governmental organizations, to multi-national corporations, to global political movements. Traditional, state-centric definitions of foreign form _or_ system of government as the policy of a sovereign state in its interaction with other sovereign states is no longer sufficient. Several alternative definitions are more helpful at highlighting aspects of foreign policy traditionally neglected. The first views foreign policy as those external goals for which the nation is prepared to commit its resources. By focusing on what a country does rather than what it says, this pragmatic definition usefull y separates a countrys rhetoric from its true intent and its material capabilities. However, lack of action can also constitute a policy-the policy of an isolationist state is defined by its very unwillingness to commit resources. A second conceptualization of foreign policy is as the range of actions taken by varying sections of the government of a state in its relations with other bodies similarly acting on the international stage...in order to advance the national interest. Notable here is the recognition that governments do not act as monolithic, static entities, and that non-state actors may at measure be as influential as states. However, the assumption that governments always know what is in the national interest and always rationally work towards its realiza... ... Presidents interests. The number of wickedness Presidents who have later become President suggests that this concern may not be entirely incomprehensible. The enormous amount of infighting and politics between (and within) departments should not be underestimated. Factions are formed, rumors spread, information leaked, and consensuses forged. When making decisions, each department will tend to concentrate on acquiring information that protects and advances its own interests or its view of the national interest. This inevitably leads to oversimplification and a favoring of men and women of action rather than deep, strategic thinkers, whose voices tend to get lost in the fray. One of the attributes of a goodly President is the ability to recognize and rectify imbalances in his administration. Failure to do so can lead to an unrepresentative and irresponsible foreign policy.
