We will write a custom essay sample on Mass of the Earth or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The reason is to show how scientists determined the mass of the Earth, and an example of one of the ways to estimate the mass of the earth. Knowing the mass of the earth is important because it helps us to understand what is in the center of the earth, and how the earth operates. Several historical figures have discovered the mass of the earth. Henry Cavendish is credited as the first person to find the mass of the Earth (Rubin). Eratosthenes calculated the size of the earth in 276 BC. Newton was incremental in calculating the mass of the earth with his equation of gravity (Wile). Today’s known mass of the earth is 5.98*10^24kg or 598 sextillion kilograms (Wile). One way to can calculate the mass of the earth is by finding the time it takes to rotate around the sun and using the equations of gravity and centripetal force to calculate the mass of the earth. This method takes equipment to calculate the mass of the sun and the velocity which cannot be done in a classroom without the information pre- given in a text book (Wile). Methods How can the mass of the earth be estimated? This experiment will show how that can be done. In this experiment the equipment used includes: six rocks given in class to calculate the average density of rocks, a graduated cylinder full of water, a calculator, and an electronic balance. One of the assumptions that I can make regarding the calculations achieved in the activity include many of the rocks have similar or even the same volume because of their size. Another premise that can be made is the densities are similar in some of the rocks in this activity. The above assumptions are justified in this experiment because three of the volumes are exactly the same in the calculations and the rocks were the same sizes. The densities are also very similar in some of the samples. The reason being is that the mineral content is similar or exactly the same, but arranged differently. One example of this mineral content is basaltic porphyry and basalt; another is granite and pegmatite. Each of these rocks has the same mineral content, but different particle sizes (Wicander, Monroe). Results To determine the mass we placed the first rock on the balance to find its mass and the answer was 25g. Secondly, the rock was placed in water to find the volume, and found the volume was 25mL which makes the density 1 g/mL. Five more rocks were measured in the same way. For the second rock the mass was 50g and the volume was 23mL, making a density of 2.17g/mL. The third rock had a mass was 77g and the volume of 25mL, making a density of 3.08g/mL. On the fourth rock, the mass was 70g and the volume was 25mL, making a density of 2.8g/mL. The mass of the fifth was 33g and the volume was 10mL, making a density of 3.3g/mL. In the final rock the mass was 15g and the volume was 5mL, making a density of 3.0g/mL. The rocks average density is 2.56g/cm3 because you can substitute cm3 for mL since they are equal. To find the mass of the earth we had to know the densities of the rock and the iron. The rock made up 65% of the earth’s material, and iron made up the other 35%. The density of the iron was given as 7,874 kg/m3.The density of iron had to be multiplied by .35 to find the final density of iron in the earth. Then the new density (2,756 kg/m3) was multiplied by the given volume, which is 1.08321e21m3 to get a mass of 2.9853e24kg. Next I had to calculate the density of the rock in kg/m3 which ended up as 2,560kg/m3. That density had to be multiplied by .65 to get the density of the total rock of the earth. The answer is calculated as 1,664kg/m3. To get the mass, I multiplied the given volume by the density of the rock, which was calculated as 1.8025e24kg. Finally to get the mass of the earth, the mass of the iron had to be added to the mass of rock. The mass of the earth was found to be 4.78e24kg. Table 1 Density in kg/m3 Volume in m3 Mass in kg Mass of the Earth in kg Rock total in earth 1,6641.08321e21 1.80246e24 4.78e24 Irontotal in earth 2,756 1.08321e21 2.98533e24 Discussion The mass of the earth calculated by me compared to the one discovered by real scientists is that mine was 4.78e24kg but the real mass was 5.98e24kg (Wile). The reason for the difference is being the water was not part of the calculation. Also what would play into this would be the amount of rocks used. It would change the density of the earth because all rocks have different densities, and the more rocks used the more accurate the density will be. Another factor is how we calculated using a geologic equation while scientists used the gravitational pull of the sun and Newton’s equations on gravity to find the mass of the earth. Ways I could improve my results include using more rocks to make a more precise average density of rocks in the earth to find a closer answer. In addition, the density of water could also be used since water also takes up a huge amount of the earth. Another way that would work is finding the density of nickel since there is a significant amount of nickel in the center of the earth, which would give a more accurate mass. Conclusion In conclusion, in this activity the densities of various rocks were calculated, then averaged. The given information was used to calculate the mass of the iron portion of the earth. After that, the mass of the rock portion of the earth was calculated. Then both of those masses were added together to give the total mass of the earth.

Cost and Quality Analysis Essays

Cost and Quality Analysis Essays Cost and Quality Analysis Essay Cost and Quality Analysis Essay Cost and Quality Analysis Effectiveness, safety, timeliness, patient-centered, equitable, and efficient are all elements of quality (McGlynn, 2005). The Institute of Medicine noticed that only half the time patients are getting effective care, disparities in direction remain extensive, medications errors are common, and enhancement of quality and efficiency could eliminate greater than 30% of healthcare costs (McClellan, 2013). It is estimated that in 2007 the national cost of healthcare was $2.2 trillion, or $7,500 per United States (US) resident. Health care expenditures explain 16.2 percent of the Gross Domestic Product and national health spending accounts for approximately 33% for hospitals, 20% for physician services, and 10% for pharmaceuticals. Costs are escalating rapidly in the US than any other country globally (â€Å"Guiding Principles,† 2008). Questions arise as to the relationship between quality and cost. Will increased cost result in superior care, or will superior outcomes assist in th e containment of cost? Indication of the direction of quality and healthcare costs are unpredictable. Studies have shown that the link between the two is small to moderate, irrespective of whether the path is positive or negative (Hussey, Wertheimer, Mehrotra, 2013). Roles The Agency for Healthcare Research and Quality (AHRQ) is a branch of the US Department of Health and Human Services. Their role is to reinforce research intended to develop the quality of healthcare, decrease its cost, improve patient safety, reduce medical errors, an expand access to vital services (â€Å"Related Public/Private,† 2008). The Joint Commission’s role is to constantly advance the safety and quality of care delivered to the public through the establishment of health care accreditation and associated services that back performance improvement in healthcare systems (â€Å"Related  Public/Private,† 2008). Activities AHRQ has many major activities that address quality and cost in healthcare. One activity is the use of risk management theory by nurses. Effective risk management necessitates nurses to identify risks before they happen to the patient. Jointly with a medication database, the medication regimen complexity index tool is used for measuring numerous characteristics of drug regimen complexity to decrease adverse reactions and higher costs, which is yet another activity used by the AHRQ (â€Å"Automated Tool,† 2013). The Joint Commission, on the other hand, has the Core Measure Solution Exchange ®. This is a web-based forum devoted to communicating solutions related to improving core measure performance rates (â€Å"Hospital Resources,† 2013). The National Patient Safety Goals is a sequence of exact activities to stop medication errors , for example miscommunication between healthcare providers, unsafe use of infusion pumps, and medication mistakes (â€Å"Joint Commission, † 2013). Both of these agencies are working together on some topics. The National Quality Measures Clearinghouse endorses extensive access to quality measures by the healthcare community (â€Å"Specifications Manuel,† 2013). It is sponsored by the AHRQ and includes Joint Commission measures. Current and Projected Initiatives AHRQ funded a national attempt to stop central line-associated bloodstream infections in US hospitals by executing a Comprehensive Unit-based Safety Program (â€Å"Eliminating CLABSI,† 2013). Another initiative that is hallmark is their support of a culture of patient safety and quality enhancements in healthcare organizations in the Nation, entitled, Hospital Survey on Patient Safety Culture. They subsidized the progress of patient safety culture assessment tools and sponsored the development of a comparative database on the survey (â€Å"Hospital Survey,† 2013). AHRQ initiated the Healthcare Cost and Utilization Project. This empowers research on a comprehensive assortment of health policy issues, comprising cost and quality of health services, medical practice models, access to health care programs, and consequences of actions at the national, State, and local levels (â€Å"Healthcare Cost,† 2013).ealthH The Joint Commission’s safety and cost initiatives revolve around quality improvements. They currently have an initiative to describe approaches for attaining improvement in the efficiency of the transitions of patients between healthcare facilities, which include continuance of safe, quality care for patients (â€Å"Hot Topics,† n.d.). They developed a tool, Targeted Solutions Tool (TST)â„ ¢ for Hand-off Communications, which gauges the efficiency of hand-offs in hospitals and between facilities and offers solutions. They also have TSTs for hand hygiene and wrong site surgery. Another initiative is the National Quality Core Measures. They have 14 different actions that have specific core measure sets under them. Some core measures that they are reviewing are perinatal care, venous thromboembolism (VTE), tobacco treatment, immunizations, and stroke (â€Å"Core Measure,† 2013). Another initiative is the Cooperative Accreditation Initiative. This initiative†™s focus is to decrease the cost and repetition of survey and review activity practiced by healthcare organizations (â€Å"Facts About,† 2013). Implications for Nurses Nurses are instrumental to the delivery of high quality and efficient care. Efforts by organizations to maintain labor costs, while maintaining quality standards, have major effects on the nursing staff. A model that depicts this is Transforming Care at the bedside. The goal is to involve front-line staff and hospital leadership to make enhancements in four areas: refining the quality and safety of care; safeguarding a high-quality work environment to entice and retain nurses; cultivating the proficiency of care for patients and families; and improving the efficacy of the entire healthcare team. An advanced degree that describes this is the clinical nurse leader role. It is intended for nurses that want to bring about positive changes, but stay at the bedside. Staffing and organization of hospital nursing influences quality and cost (Needlemen Hassmiller, 2009). What nurses do affects the patient’s quality of care and hospital cost. Nurses provide continuous monitoring and as sessment, provide interventions to decrease or prevent complications and harm, collaborate with other healthcare workers, and provide education. Analysis shows that the biggest cost savings of increased staffing result  from decreased lengths-of-stay (LOS). Reduced stays not only reveal decreased problems that prolong stays, but the aptitude of nurses to perform their work and manage the work of others in a timely and effective way. This demonstrates their capability to affect efficiency as well as quality (Needlemen Hassmiller, 2009). Emergency departments are diligently looking at ways to decrease LOS. The insinuation of the evidenced-based practice (EBP) competency for nurses indicates that nurses are required to research the best resources of evidence; express strong, quantifiable questions; and understand how to assimilate new findings into practice (Wakefield, 2008). An example is the direction that organizations are moving to have work environments and procedures be lean, thus improving quality, process, cost, and production. Nurses will need to use EBP to work more efficiently and be lean. Conclusion Improving the quality of hospital organizations has become an extremely notable public and private business, as clients, accreditors, and private facilities try to set norms and inspire accomplishments. Simultaneously, the management of hospital costs has been in the forefront. Attempts to influence labor costs have key effects on nurses. Many organizations are coming up with strategic ways to improve this quality, while controlling costs. The AHRQ and The Joint Commission have been enormously helpful in assisting hospitals with ways to improve quality by maintaining the basic elements of effectiveness, safety, timeliness, patient-centered, equitable, and efficient nursing care. They reveal opportunities to support our customers, healthcare workers, and healthcare organizations in improving care and thus preventing needless health care costs.

Persuasive Essay

Persuasive Essay The primary purpose of persuasive essay is to persuade or convince the reader that a certain claim or viewpoint is right. A persuasive essay can be written from either a subjective or an objective point of view simply because persuasion is found in a variety of settings: from informal communities to large formal groups. What Is a Persuasive Essay A persuasive essay is one of the common types of essays. As its name suggests, the primary purpose of this essay is to persuade or convince the reader that a certain claim or viewpoint is right. A persuasive essay can be written from either a subjective or an objective point of view simply because persuasion is found in a variety of settings: from informal communities to large formal groups. Therefore an assumption can be made that persuasive essays are given to students of all educational levels to hone their persuasive and argumentation skills. Obviously, persuasive essays train written skills, allowing students to read around, search for proper arguments or think carefully what points should be brought up by in a persuasive essay. HOW TO WRITE A PERSUASIVE ESSAY The next step in persuading your audience is oral persuasion, which refers to oratory skills. The latter are harder to master but are an essential skill to acquire. Therefore, a persuasive essay can be viewed as an assignment that is given to students during their later high school or early college/university years to help them better master the art of conviction. Persuasive Essays vs. Argumentative Essays These two essay types resemble each other like two identical twins. However, there is a slight difference that allows you to tell those twins from one another. That difference stems from the purpose of each essay, so lets review them briefly. The main goal of the persuasive essay is to persuade the audience, while the primary purpose of argumentative essays is to bring up the argument, voice the pros and cons, the strengths and weaknesses and generally to describe things or events in their duality. As an illustration, compare the way a persuasive essay topic sounds to how the argumentative essay topic is put: Persuasive Essay Topic: Smoking  should be banned. Argumentative Essay Topic: Should smoking be banned? TOP 101 PERSUASIVE ESSAY TOPICS As seen from the example above, in the persuasive essay the topic is introduced in the form of a declarative sentence. It implies the reader that the statement is true and text in the body of the essay will support the topic. The argumentative essay topic is actually a question, which prompts the discussion. The question invites the author and the reader to look for all possible choices and all possible arguments. Respectively, contents of each paper will differ depending on its topic. Persuasive Essay  Outline Unless specified otherwise, persuasive essays will take the 5 paragraph format. This means that the persuasive essay will contain the following structural elements: the introduction with the topic sentence, two to three body paragraphs, and a conclusion. The introduction will present the problem to the reader and will simultaneously serve as an attention getter. Body paragraphs will elaborate in greater detail on the information presented in the introduction. The language in your persuasive essay can be either formal or informal that depends entirely on your audience. We have a great article that explains essay structure in the greater detail. The language in your persuasive essay can be either formal or informal that depends entirely on your audience. If you are trying to convince a friend or a relative, the informal language would make sense; however, if you are writing for a formal group (teacher, unknown people), then it would be best to use the formal style. Transition Words for Persuasive Essay Agreement and Comparison: also, and, likewise, in addition; Opposition and Contradiction: rather, but, and or; Cause and Purpose: in that case, as a result, under those circumstances; Effect and Outcome: accordingly, thus, consequently, then; Result: as shown above, as can be seen, in the final analysis, all things considered.

Contemporary - Essay Example Lastly, technological advances such as synthesizers became prevalent in the field of music and began to be used in ways classical music had never before experienced. Naturally, such a time of political and societal unrest gave way to many new ideologies, new movements, new perspectives, and most importantly for purposes of this brief analysis, new forms of classical music. Classical music composers were faced with all of the aforementioned issues and in addition to that were given new tools with which to accentuate their music. The birth of the synthesizer and the use of computers in musical compositions were both immediately co-opted into music as composers and musicians alike attempted to delineate their music through their use. Likewise, greater and more prolific use of atonality, dissonance, and minimalism were employed to a greater and greater extent. Arnold Schoenberg, a composer whose career spanned both 20th century and contemporary periods, will be analyzed in this brief study. Schoenberg’s characteristically atonal, experimental, and minimalist styles can be amply heard in A Survivor of Warsaw Op. 46 1947. The piece is symbolic of Schoenberg’s unique style, the elements of the contemporary period, as well as the socio-political disturbances that gave rise to so much of the anxt filled music of the era. Firstly and most prominently, the piece features Schoenberg’s full and extravagant use of atonality and dissonance which had become such a characteristic of the prior 20th century; however, in addition, Schoenberg fully employed the 12 tone technique (also known as dodecaphony) for which he became renowned. This piece critiques modern society in that the atonality, the purposeful confusion, and the minimalism all work towards describing the sheer and utter depravity of humankind without taking away from the story by an overly ornate or complex musical tone. Simply stated, where other pieces may have lost some meaning by purposely

Individual Experience of Working at a Prestigious Bank Essay

Individual Experience of Working at a Prestigious Bank - Essay Example I had a partial English education and could converse in English without difficulty. Although she had a thick African accent and a way of speaking, which is, at best called â€Å"cart before the horse,† the unabashed African made herself clearly understood. Other two Asians, coming from different parts of Asia, found it an uphill task to hold an ordinary conversation. But I could see that they were learning fast. People took some time to understand our accented and rather hurried way of speaking and this was, at times, a huge embarrassment. In frustration sometimes, we blamed it on the racism prevalent in the UK, although we knew that we were being unfair. African had an aggressive ‘back home’ accent and was unexpectedly comfortable with it. We had initial problems to understand the original British English, and had always been nervous if someone spoke to us directly. Slowly we started understanding the British way of speaking and that problem was partially left be hind. It is fantastic that we know a common language, even though at varying degrees of fluency. â€Å"For many theorists within mainstream linguistics, the term discourse signifies a turning away from sentences as exemplars of usage in the abstract, that is examples of the way that language is structured as a system, to a concern with language in use.† Brown and Yule (1983, taken from Mills, 1997, p. 9). Discourse across race and regions has many colors and shades. Our discourse that has remained formal even to this day with the British also shows the delicate nature of our relationship. It took only a few days for the rest of us to be informal. With formal conversation, very often one hits a brick wall. â€Å"What I have said is not ‘what I think’ but often what I wonder whether it couldn’t be thought,† said Foucault (1979d. 58) (Taken from Mills, 1997, p. 14). Language and discourse are crucial in cross-cultural  interactions and mostly becomes the sole reason of hindrance in furthering a friendship.  

Finding White Elephants in Dialogue Essay Example for Free

Finding White Elephants in Dialogue Essay Ernest Hemingway’s â€Å"Hills like White Elephants† presents its main subject not in a blatant manner but through the sum of what is implied and what is said. The title itself alludes to the negativity in which the situation is being accepted by the two main characters, though at varied levels. While the American man perceives their situation as the â€Å"white elephant†, the girl does not think so, at least not as much. This may be because she can think of another white elephant in her life. Meanwhile, the real action happens in the interaction between the American man and the girl, named Jig. Therefore, the text requires careful observation of human relationship in action. Furthermore, perusal of dialogue and even some symbolism reveal the couple’s reaction to that pregnancy and their contemplation of ending the â€Å"problem† or â€Å"white elephant† through abortion. A â€Å"white elephant† is after all â€Å"a metaphor for an expensive and burdensome property† (Link 67). In this short story, through the aid of dialogue the reader can perceive that the white elephant can represent something more subtle than Jig’s pregnancy; it can represent the man’s weakness and inability to take responsibility for his actions. The differences between the American man and the â€Å"generic† girl are emphasized subtly, but these differences affect the way in which the relationship can be interpreted, especially through these differences’ effects on the quiet but steady unraveling of the relationship. For example, the very appointment of a nationality to the man signifies that the girl is foreign, and therefore different from him. â€Å"In an impressive dialogue-driven narrative prose, Hemingway’s unnamed American male protagonist dominates the meeker, weaker-sexed Jig†¦Ã¢â‚¬  (Rankin 234). They are separated by culture, nationality, gender and even by age. The American man has not impregnated a woman who may be nearer his supposed level of maturity and responsibility, but a young girl who he may have seduced. The fact that he is the one who cannot take responsibility for the pregnancy is ironic. It is also difficult for a girl who may naturally have expected to lean on an older man during crisis. In contrast to the idea that Jig is a young innocent who has been seduced and can be easily manipulated is Jig’s display of wit as compared to the more reactionary older man (Rankin 236). Jig sometimes denies degree of knowledge such as her familiarity with Anis de Toro: â€Å"I don’t know†¦is it good with water? (Hemingway)†. However, her conversation reveals that she is not as ignorant nor naive as she seems. She may be young but she is not to be swayed into making a decision just because it will please her lover. She says â€Å"Everything tastes like liquorice, especially all the things that you’ve waited for so long, like absinthe† (Hemingway). Jig is exerting some will, declaring what she wants but not directly. The point comes across anyway. While the man thinks of her pregnancy as the white elephant in their relationship, she does not believe it to be so: â€Å"They are lovely hills. They don’t really look like white elephants. I just meant the coloring of their skin through the trees† (Hemingway). Jig believes that although the pregnancy may be difficult on both of them, it promises something beautiful. She has her own opinion on the situation and is not afraid to say what is in her mind. Because there is an emphasis on the meaning of conversation in â€Å"Hills like White Elephants†, in this â€Å"barely 1500 words long [short story], repeated items are notable† (Link 67). It is through repetition that ideas and the story itself are instilled into the readers’ minds despite the ambiguous dialogue and seemingly mundane setting. â€Å"The couple’s power relationship also emerges in the prominence of questions in the text. Much of the dialogue†¦is a trading of questions and answers in which Jig asks a total of seventeen questions, thirteen of which are yes-no questions. The man only asks four questions, three of which he does not ask until the text is nearly finished† (Link 68). The couple is therefore engaged in a verbal tug of war in which each tries to achieve the agreement of the other. Jig is more curious and assertive, despite the fact that the man is expected to have more power over her, because of his gender and more mature age. She asks more questions about their situation, is almost pulled towards the man’s argument but continues to wonder openly about their situation. This questioning mind prevents her from fully regarding her pregnancy as a white elephant. â€Å"Hills like White Elephants† is a testament to the power of dialogue; though the wordings are not direct, the repetition makes up for any diminishing of clarity. The subject of whether or not to have an abortion performed on Jig has been handled in a subtle manner which separates it from other short stories, and even novels that deal with pregnancy out of wedlock and the question of what solution to take. Even what the metaphor will represent can be contested: if indeed the white elephant or burden is the pregnancy or the American man himself. Works Cited: Hemingway, Ernest.

Drones: Unmanned Aerial Vehicles Essay -- UAVs Technology Essays

Like much of today’s technology, Unmanned Aerial Vehicles attribute their creation to the military. The idea of using unmanned aircraft has long been a dream for the military -- scouting planes without any casualties to report should something go wrong, air strikes with only time and money to lose, and the ability to wage war without losing a single life. Well the third one may perhaps not be realistic – as Afghanistan has shown, lack of ground troops leaves certain entities unchecked.1 However, it may be argued that â€Å"they represent a significant step toward the eventual automation of the battlefield—one in which teleoperated or robotic systems replace many soldiers.†2 Either way, these machines do create a less expensive and more dispensable alternative to conventional air battles. This creates obvious moral issues, as the country with such technology is no longer as tentative to engage in armed combat. UAVs can do many things that conventional aircraft cannot. As Steven Ashley puts it, â€Å"’Traditional’ aircraft—fast photo/ reconnaissance fighters, high-flying U-2s, and sensor-laden patrol planes—nor the classified orbital spy satellites can do the job of the simple, prop-driven unmanned aerial vehicles.†3 These advantages, coupled with their low expense, place them in great demand. As Ronald R. Fogelman (U.S. Air Force Chief of Staff) states, â€Å"We are now impressed by the convergence of technological advances in computers, flight controls, lightweight materials, advanced electric motors, and communications packages that will make modern UAVs extremely effective.†4 UAVs are not only to be used for such questionable moral circumstances as war; these vehicles can provide a plethora of services in the commercial market.

Table 2 reflects the Health Promotion Program’s effects on cardiovascular risk factors and Table 3 is reflective of the program’s effects on health behavior. 2. Which t ratio in Table 2 represents the greatest relative or standardized difference between the pretest and 3 months outcomes? Is this t ratio statistically significant? Provide a rationale for your answer. 3.Which t ratio listed in Table 3 represents the smallest relative difference between the pretest and 3 months? Is this t ratio statistically significant? What does this result mean? The T-ratio is 0. 80. This value is not statistically significant since it is less than the tabulated value of 1. 96. This is indicative of the program having no effect on health behaviors. 4. What are the assumptions for conducting a t-test for depe ndent groups in a study? Which of these assumptions do you think were met by this study? Several assumptions for t-test for dependent/matched groups in a study are applied.First, it is assumed that the difference between the two groups of the dependent t-test is approximately or normally distributed. Second, the dependent variable is interval or ratio (continuous in nature). Third, any independent variable consists of one group or two â€Å"matched pair† groups. Finally, all subjects are assumed to have been surveyed the same and data collection was unbiased. The assumption that was met in this study is the normal distribution. 5. Compare the 3 months and 6 months t ratios for the variable Exercise from Table 3.What is your conclusion about the long-term effect of the health-promotion intervention on Exercise in this study? After comparing the t-ratios for the Exercise variable, I conclude that there is an effect on long term exercise and health behaviors. 6. What is the smal lest, significant t ratio listed in Table 2? Provide a rationale for your answer. The smallest t-ratio in Table 2 is 2. 04. It is statistically significant because it is > 1. 96. 7. Why are the larger t ratios more likely to be statistically significant? The larger t-ratios are statistically significant because they tend to be larger than the table value f 1. 96. 8. Did the health-promotion program have a statistically significant effect on Systolic blood pressure (BP) in this study? Provide a rationale for your answer. No. The program did not have a statistically significant effect on systolic BP. The t-test values are lower than 1. 96 on the t-distribution. 9. Examine the means and standard deviations for Systolic BP at pretest, 3 months (completion of the treatment), and 6 months. What do these results indicate? Are these results clinically important? Provide a rationale for your answer.The results for standard deviations for Systolic BP at pretest, 3 months (completion of the tr eatment), and 6 months indicate that they the programs did not affects it. This is clinically important because it supports that the data is normally distributed and there is not a high likelihood that data was widely dispersed. 10. Is this study design strong or weak? Provide a rationale for your answer. The study design is strong. This is because it has been carried out using the right procedures for research. The presented results show a stronger impact in the intervention.Also, the sample could easily be representative of the population in question. Bonus Question: Would you, as a health care provider, implement this intervention at your facility based on the Total Risk Score results? Provide a rationale for your answer. Yes, I would implement the intervention at my facility because it was clear, concise and showed that the program had long lasting positive effects while utilized. The fact that some of the data started decreasing (showing that intervention was helpful) at the 6 month follow up reinforces the good outcomes with such a program in place.

A Comparative Study of the Field Criminal Justice and Criminology

A Comparative Study of the Fields Criminal Justice and Criminology Javier Landa-Miranda Ivy Tech Community College CRIM 101 What is Criminal Justice and what is Criminology? They are the same? Those are the questions that people ask their selves when they talk about those fields. There might be many controversies about the differences and similarities about Criminal Justice and Criminology. People must think that these two fields are totally different or just the same thing. The reality is that Criminal Justice and Criminology are two fields that have many differences but at the same time many similarities.To identify the differences and similarities first, we have to identify what is Criminal Justice and Criminology. What is Criminal Justice? Well, for sure is not specific job training or a class that someone can take and considered him or herself ready to serve as a police officer, detective, etc. On the other hand, Criminal Justice is the study of how justice is dispensed in our s ystem of government and around the world. Also Criminal Justice is the system of practice of governments directed at upholding social control, deterring crime, and sanctioning those who violate the law.The study of Criminal Justice will help anyone to identify the different jobs where people can get involved with a degree in Criminal Justice. Another important factor to note is that police agencies, courts, and corrections are part of the system of Criminal Justice. Each of those three components plays different functions in the Criminal Justice System (Judge Harold). Actually, society has a conflict with Criminal Justice System about Individual Rights and Public Order. This conflict refers to the question: what are more important Individual rights or Public order?This has been a serious issue for the Criminal Justice System because they try to balance both to maintain order in society. Is important to know that Criminal Justice has a process, know as Due process or Bill of Rights. This process protect criminals rights and is required by the U. S. constitution and force Criminal Justice case processing be conducted with fairness and equity. This means that a criminal can’t be arrested or send it to jail without fallowing the correct process that will protect criminal’s rights. Criminal Justice lso has several conflicts inside his own field with his agencies (The Defendants). The consensus model and conflict model are the more common. Consensus model refers to government agencies that work together against crime to maintain order. In the other hand, conflict model means that agencies win more when they compete each other instead of working together to maintain order; this last model has been a serious issue to Criminal Justice System because this can make complicated to maintain public order and keep safety in the streets.People as police, detectives or special agents that work in the criminal justice field have a lot of purposes in democratic soc iety, but the most important for them are: enforce the law of the society, apprehend criminals, prevent crime, preserve domestic peace and tranquility, and provide the community with needed enforcement-related services (Major Cities). Criminology is the study the origin, extent, and criminal behavior including factors and causes of crime. College students that follow Criminology as a career, learn about different types of crime and how public responds to crime.This field focuses more in the psychology and ideology of a criminal (Criminology 2010). Criminology always is trying to solve the question, why crime occurred and why people commit them? This is why Criminology prepares a student to understand criminal’s behavior. Criminologists are mainly concerned with identifying the suspected cause of crime. Even though some criminologists devote their research to justice and social control and are concerned with how the agencies of justice operate. Criminology, 2000). Unlike Crimi nal Justice, Criminology has different methods of research as: surveys, experiments, observing and intensive interviewing, research using existing data, and comparative and historical research. This process has to be done to prove theories and hypothesis related to a crime investigation. Even though, is common for Criminology courses to evaluate the agencies of justice and for Criminal Justice programs to feature courses on Criminology.The higher level of education the more possibilities to get a higher position at any agency related with his career. Sometimes people find hard and cannot differentiate between Criminal Justice and Criminology. This happen because between these two fields there are not many differences, on the other hand there is more similarities then people think. The only differences between these two fields are: Criminal Justice is more related with crime control and how is punished. That is why Criminal Justice focuses more in policing, corrections and criminal c ourts.The main purpose of Criminal Justice is to prevent crime and apply the law to whoever broke the law (Criminal Justice 2013). On the other hand, criminology focuses more in the behavioral and social science that explores the origins of criminal behavior and the social response to crime. Another difference of Criminology is the application of the scientific method to understand and explain interactions of why people commit crime, law-making, law-breaking, and the reactions of society to these processes (Criminology and Criminal Justice).On the other hand the similarities of these two fields are easier to understand and explain. Sometimes Criminology is called Criminal Justice and other people thinks that these two fields are so inter-related that they should be considering as a discipline. As well as Criminal Justice, Criminology is related to courts, and police departments, the only difference is that Criminology focuses in why people commit crime, when Criminal Justice in how and what punishment the criminal should received (Criminology and Criminal Justice).Both fields Criminal Justice and Criminology agree that the cause of violence is related to: socialization, exposure to violence, cultural values subculture of violence, personal traits and human instinct (Criminology 2010). A student in Criminology as well as a student in Criminal Justice can become member of a police department, a special agency, or courts. Even with a Criminology degree that same person can perform the work of another person with a Criminal Justice degree.Criminal Justice and Criminology are two different fields; however might be hard to some people to distinguish these two fields due to the similar aspects. Even though, the study of these fields had brought many controversies and different point of view about the relation between these fields. People, who are interested in these two fields as a future career, might find hard to identify the differences and similarities. It is imp ortant to have a clear idea what is the role of each field before choose one.This essay might not clarify everyone’s questions but gives an idea of how Criminal Justice and Criminology works and how each field performs its work. Even thought, there might be appear new questions and controversies about these two fields that will need to be solve. References For a good overview of the issues involved, see Judge Harold J.

Socrates, Plato and Aristotle Essay Essay Example

Socrates, Plato and Aristotle Essay Essay Example Socrates, Plato and Aristotle Essay Essay Socrates, Plato and Aristotle Essay Essay Socrates was born in Athens about 470 BC and lived until 399 BC. he was a classical Grecian Athenian philosopher and is credited as one of the laminitiss of Western doctrine. An accurate image of the adult male. his life. and point of views are debatable because he did non compose any philosophical texts. everything we know is based on Hagiographas by his pupils and contemporaries†¦ this is what is known as the Socratic job. Socrates was subsequently tried and put to decease for â€Å"corrupting the young person and impiety† . Throughout his life Socrates neer wrote anything down because he believed cognition was a living synergistic thing and non to be written in a inactive authorship ( I bet the cyberspace would hold truly appealed to his love of synergistic treatments ) . so his typical method of philosophical enquiry consisted of oppugning people on their places and working them through inquiries until they reached a contradiction. therefore turn outing to them that their original averment was incorrect. Socrates most celebrated philosophical thoughts: The necessity of making what one thinks is right even in the face of cosmopolitan resistance. and the demand to prosecute knowledge even when opposed. which he did stop up paying the monetary value for these thoughts in the terminal. Socrates was unconcerned with physical or metaphysical inquiries ; the issue of primary importance for him was moralss and populating a good life. During his test and written in Plato’s â€Å"The Apology† he gave the thought that truth demands to be pursued by altering your place through oppugning and struggle with opposing thoughts. It is THIS thought of the truth being pursued. instead than discovered. that characterizes Socratic idea and much of our â€Å"Western† philosophical thought today. Plato: Plato was born in around 428 BC and lived until 348 BC. he was a classical Hellenic philosopher. mathematician. author of philosophical duologues. and laminitis of the Academy of Athens†¦ which was the first establishment of higher acquisition in the Western universe. Plato was a pupil to Socrates and was a instructor to Aristotle and was instrumental in puting the basis of Western doctrine and scientific discipline. He was a superb author and one the most influential writers in the history of Philosophy. The cardinal facet of Plato’s idea is the theory of â€Å"ideas† or â€Å"forms† . Plato believed the universe that appears to our senses is in some manner filled with mistake. or faulty. He believed there is a â€Å"perfect realm† . populated by entities otherwise known as â€Å"forms† or â€Å"ideas† that are ageless. changeless and in some sense related to the construction of our universe. Plato urges us to transform our values by taking to bosom the greater world of the signifiers and the faultiness of the life universe. He says we must acknowledge that the psyche is a different kind of object from the organic structure ; it does non depend on the being of the organic structure for its operation. This says that the psyche can so hold on the nature of the signifiers far more easy when it is non encumbered by its fond regard to anything in the physical universe. In Plato’s most influential duologue called â€Å"The Republic† he deals with his ideas about â€Å"forms† in a transition discoursing captives of the cave and his abstract presentation of the divided line. Worlds live in a universe of seeable and apprehensible things. The seeable universe surrounds us†¦ what we see. hear and see. this topographic point is a universe of alteration and uncertainness. The apprehensible universe is made up of unchanging merchandises of human ground such as mathematics ; this is the universe of world. This apprehensible universe contains ageless â€Å"forms† of things. For illustration the signifier or thought of a Canis familiaris is abstract and applies to all Canis familiariss ; this signifier neer alterations. If all the Canis familiariss in the universe were to disappear the signifier still would non alter. A Canis familiaris is a physical changing object and can alter or easy discontinue to be. but the â€Å"form† or â€Å"idea† neer alterations. Aristotle: Aristotle lived from 384 BC to 324 BC. was a Grecian philosopher and pupil of Plato and instructor to Alexander the Great. His composing covered non merely doctrine. but natural philosophies. metaphysics. poesy. theatre. music. linguistics. moralss. biological science and the list goes on. Together with Plato and Socrates. Aristotle is known to be one of the most of import initiation male parents of Western doctrine. His Hagiographas were the first to really make a comprehensive system of Western doctrine. Aristotle studied under Plato. but he basically disagreed with him on merely about everything it seems. He could non believe of the universe in such abstract footings as Plato did. he believed the universe could be understood through elaborate observation and cataloging of phenomenon. As a consequence of this belief. he wrote about everything from political relations to poetry. from anatomy to natural philosophies. Grecian doctrine up to this point chiefly dealt with the survey of cognition and inquiries of certainty ( i. e. suppose nil is existent? ) . Aristotle approached the inquiry by categorising based on their objects and the approx. certainty you could cognize those objects. For case. certain objects permit you to hold a cognition that is true all the clip. let’s usage geometry as an illustration. when we say a trigon is a polygon with three corners. it ever has that description and is true all the clip. this type of cognition is based on certainty and precise accounts. Other objects such as normal human feelings don’t license certainty. for illustration if you were to diss person you don’t cognize if they would be angry with you or non. This type of cognition is based on chance and imprecise accounts. As Aristotle put it. â€Å"One can non anticipate the same degree of certainty in political relations or moralss that one can demand in geometry or logic† .

Free sample - Cannabis. translation missing

Cannabis. CannabisAccording to Brown (1998), Cannabis can be defined as a genus among the flowering plants comprising of three recognized species namely, Cannabis indica, Cannabis ruderalis, and Cannabis sativa. The three classifications are autochthonous to South Asia, and Central Asia. Cannabis is a very unique plant that is used for a number of reasons, both positive and negative and its uses can affect the entire global society. Cannabis is known by a number of names, for instance, Marijuana, Grass, Attention Getter-weed, Dope, and Pot. For a number of years, there has been a stigma accompanying the Cannabis plant and it has been seen as an inherently evil plant by most of the people in any given society. Apparently, it is the use or misuse of the plant that is bad or good, and not the plant itself. Cannabis can be eaten, smoked, or drunk just like tea. If Cannabis is taken in low doses it can bring about a relaxed state of mood while higher doses of Cannabis may bring about euphoria. It has been clear that, not every individual sees positive consequences from cannabis, for instance, most of the novice users and the high dose steady users have experienced increased paranoia or anxiety. It has been found that the main active ingredient of cannabis called delta-9-tetrahydrocannabinol, affects processing of information as well as speed of response such that the activities that involve skilled responses like driving can be affected negatively (Nahas Latour, 1993).  Ã‚   Cannabis is a long-lasting hemp plant. Over many years, the cannabis plant has been used to manufacture a variety of products namely, pulp, seeds, and medicine. The Cannabis plant pulp has been used as fuel and as a raw material for making paper. The seed has been used in foods but the oil that is extracted from the seed can be utilized as a base for varnishes and paints. The leaves and blossoms of the hemp plant excrete a sticky resin which is usually used in a number of medicinal functions and in most cases for entertaining people as they abuse its use (Potter Joy 1998). Most consciousness-altering drugs comprise of both constructive and destructive effects. Apparently, people use drugs following their constructive effects but most of them are not aware of the possible destructive effects. Therefore, it is the ratio of the constructive to destructive effects that propels much of the debates regarding drugs. Some individuals perceive the use of Cannabis as a better option, while for other people the use of Cannabis is more casual. Just like all the other substances, there is a possible price that can be paid regarding the risks to one’s health (Brown, 1998). References Brown, D., (1998). Cannabis: the Genus Cannabis.

Free topic (contact me by email) - Research Paper Example Non-verbal forms of behavior are expressive while verbal behavior is indicative. In a normal communication between two people, only one-third of the meaning is transmitted on a verbal level while two-thirds on a non-verbal level (Sielski, 1979). Nonverbal communication provides an insight into why people behave as they do. Such insight and information is invaluable for professions such as counseling because body language can actually contradict verbal communication (Sielski, 1979) and non-verbal cues are processed differently in different cultures (Yammiyavar, Clemmensen & Kumar, 2008). Terms ‘body language’ and NVC are interchangeably used throughout the paper. This subject has been of interest to evaluate how an understanding of body language can actually influence counseling. I have gone through some literature on body language and counseling and since I intend to enter the counseling profession, I felt motivated to go deeper. This research paper is purely based on textual analysis. Based on the literature review, the framework for the research would be formed. The methodology would be briefly discussed and then the findings would be analyzed based on theoretical framework. Body language as a means of communication has been of immense interest to many researchers and psychologists. It is considered to be an outward reflection of a person’s emotional state, according to Yammiyavar, Clemmensen and Kumar (2008). It is a study of the mixture of all body movements that could be involuntary or deliberate; it could also apply only in one culture or across all cultures. Non-verbal communication refers to all stimuli generated for the purpose of communication. Various body movements such as facial expression, gestures, eye contact, tactile communication and paralanguage have been identified as principle non-verbal cues. Areas of study in non-verbal cues
