Which descriptive numerical measure best describes the variable Ethnicity? Use SPSS to output ONLY that one numerical measure. Include it here. Why is that numerical measure the most appropriate? What information does that measure tell you about the students in the Statistics Class (Stat_Grades.sav)? Solution Ethnicity is used increasingly as a key variable to describe health data, and ethnic monitoring in the NHS will further stimulate this trend. We identify four fundamental problems with ethnicity in this type of research: the difficulties of measurement, the heterogeneity of the populations being studied, lack of clarity about the research purpose of the research, and ethnocentricity affecting the interpretation and use of data. Ethnicity needs to be used carefully to be a useful tool for health research. We make nine recommendations for future practice, one of which is that ethnicity and race should be recognised and treated as distinct concepts. Epidemiology is the study of the distribution and determinants of disease. The main method of study, particularly for investigating the causes of disease, is to compare populations with different risks of disease. Ethnicity is a variable that is used increasingly to define populations for epidemiological studies. Differences by ethnicity in both the characteristics of populations and their experience of disease have been easy to describe, and the literature on ethnicity and health is large and growing.1We consider here the nature of ethnicity, the attributes of sound epidemiological variables, the measurement and value of ethnicity as an epidemiological variable, and how ethnicity might best be used in future research. By reviewing critically ethnicity as a variable in epidemiology we hope to facilitate better research. This review is relevant to ethnic monitoring in the NHS..

Black, Hispanic, and AIAN students remain underrepresented among medical school matriculants compared with the US population. This underrepresentation has not changed significantly since the institution of the Liaison Committee of Medical Education diversity accreditation guidelines in 2009. This study’s findings suggest a need for both the development and the evaluation of more robust policies and programs to create a physician workforce that is demographically representative of the US population.

English 101 Essay #3: Ad Analysis Throughout this course we have looked at various aspects of our culture from gender stereotypes and labels, to media and how these impact our daily lives. The articles “Male body Imaging” and “Damage Done: Crack Babies Talk Back,” along with the brief clip of the video Killing us softly, show us just how much advertising and media not only influence our purchases, but also our identity, values, and perceptions. Advertisements can be found all around us: In magazines, commercials, popups, while using the internet, social media, apps, and even on billboards while we drive. Corporations spend large amounts of money to try and sell us things on a daily basis. However, they are not only trying to sell us products, they attach ideologies, and psychological strategies using logical, ethical, and emotional appeals to persuade us. In this essay, I will ask you to consider the topics we have discussed in this course, and how they are used in media and advertisements. You will analyze a printed advertisement and use it as a visual text, and just like a textual analysis you will explain its various layers, from what it is depicting on the surface, to the message it is trying to convey, and how and why it is conveying it. What are they showing you? What are they trying to make you think? Who is their target audience? What specific elements of the ad are used to communicate its message, and reach its target audience? Consider not only rhetorical appeals such as ethos, pathos, and logos, but also other layers such as how space is used in the ad, text, colors, body language, etc. ( Do not just point out what a specific element is doing, elaborate on the significance). Directions: 1. Find a full-page real (not fake) advertisement, either from a magazine or online. 2. Analyze the ad and formulate a clear thesis that distinguishes what the message, target audience, and purpose are. 3. Develop body paragraphs that explain your thesis (one aspect per paragraph). 4. After a thorough analysis, explain if the ad is effective and how or why it is or is not effective. What is the significance of this kind of advertising in society? 5. Do not use outside sources on this essay, only the advertisement. Essay requirements:  3-5 pages (at least three spilling onto four)  10% deduction if page requirement is not met  MLA format (12 pt. font, Times New Roman)  Peer Review and rough draft must be attached to the final draft.  Do not use “I” Rough Draft due: 11/2/2016 Final Draft Due: 11/9/2016 BELTRAMI, SHOUSE, AND BLAKETRENDS IN INFECTIOUS DISEASES Trends in Infectious Diseases and the Male to Female Ratio: Possible Clues to Changes in Behavior Among Men Who Have Sex With Men John F.

Descriptive Epidemiology HIV/AIDS was first recognized as an epidemic in the United States in 1981. At the beginning of the AIDS epidemic, the life expectancy for infected persons was less than 7 years. Today, because of research and new treatment options, people who begin treatment soon after diagnosis can expect to live a nearly normal life span (Cairns, 2010). The HIV/AIDS epidemic was identified through descriptive epidemiology. Descriptive epidemiologic studies are often conducted as precursors to analytic studies. Epidemiologic concepts are used to gather data to better understand and evaluate health trends in populations. Data such as characteristics of the persons affected, place where an incident occurred, and time of occurrence are collected and analyzed to look for patterns in an effort to identify emerging health problems. In this Discussion, you will apply the epidemiologic concepts of time, place, and person to a specific population health problem. To prepare: Consider a variety of population health problems, and then select one on which to focus for this Discussion. Identify a specific population affected by your selected health problem. Research the patterns of the disease in your selected population using the epidemiologic characteristics of person, place, and time. Explore three to five data sources presented in the Learning Resources that could aid you in describing the population and magnitude of the problem. Analyze the strengths and limitations of each data source. Consider methods for obtaining raw data to determine the variables of person, place, and time for your health problem. Ask yourself: How would the methods I select influence the accuracy of case identification, definition, and diagnosis? By tomorrow Wednesday 03/07/18 by 4pm, write a minimum of 550 words in APA format with a minimum of THREE scholarly references from the list of required readings below. Include the level one headers as numbered below: Post a cohesive response that addresses the following: 1) Evaluate your selected health problem in the population you identified by describing THREE to FIVE characteristics related to person, place, and time. 2) Appraise the data sources you utilized by outlining the strengths and limitations of each. 3) Discuss TWO methods you could use to collect raw data to determine the descriptive epidemiology of your health problem, determine how these methods would influence the completeness of case identification as well as the case definition/diagnostic criteria used.

When did Industrial Revolution happen ? What is the most important machine tools invented at that time ? When did Industrial Revolution happen ? What is the most important machine tools invented at that time ? Solution Industrial Revolution can be defined as the period or process of change to new manufacturing processes in the period from about 1760 to sometime between 1820 and 1840. The process of Industrial Revolution began in Britain in the 18th century and from there it spread to other parts of the world. The most important machine tools invented during industrial revolution can be elaborated or listed as below:- 1)John Kay\'s Fying Shuttle:-John Kay, was a mechanic from Lancashire.He patented the flying shuttle. Using cords attached to a picking peg, a single weaver, using one hand, could operate the shuttle on the loom. With this invention it took four spinners to keep up with one cotton loom, and ten people to prepare yarn for one weaver.So while spinners were often busy, weavers often waited for yarn. As such, the flying shuttle effectively doubled a weaver\'s production of cloth. 2)James Hargreaves\' Spinning Jenny :-In the year1764, James Hargreaves invented the Spinning Jenny,which was a device that allowed one person to spin many threads at once, further increasing the amount of finished cotton that a worker could produce. By turning a single wheel, one could now spin eight threads at once, a number that was later increased to eighty. The thread, unfortunately, was usually coarse and lacked strength. Despite this shortcoming, over 20,000 of the machines were in use in Britain by 1778 .3)Richard Arkwright\'s Water Frame:-In the same year1764, Richard Arkwright created the Water Frame to produce yarn faster . The \"Spinning-Frame,\" as it was known earlier, was too large to be operated by hand. After experimenting with other sources of power, he decided to employ the power of a water wheel, and his machine became known as the water frame . Rollers produced yarn of the correct thickness, while a set of spindles twisted fibers together. The machine was able to produce a thread far stronger than any other available at the time. 4)Samuel Crompton\'s Crompton\'s Mule :- In the year 1779, Samuel Crompton combined both the spinning jenny and the water frame to create a machine known as Crompton\'s Mule, which produced large amounts of fine, strong yarn. 5)James Watt\'s Steam Engine :- In the year 1769, James Watt patented the steam engine and hence created a new source of power. Early-model steam engines were introduced to drain water and raise coal from the mines, but the crucial development was the use of steam for power. The first steam engine was actually produced by Thomas Newcomen, but Watt later improved and patented it. We must be aware of the fact that original idea was to put a vertical piston and cylinder at the end of a pump handle and then to put steam in the cylinder and condense it with a spray of cold water. Then the vacuum.

Why do I want to add a pole to a closed loop transfer function. Keep your answer short. What are the types of stabilities? What type of system is marginally unstable. Solution Problem 3 Effect of adding pole to closed loop transfer function The addition of left half pole tends to slow down the system response. The effect of addition of pole becomes more pronounced as pole location drifts away from imaginary axis. Addition of right half pole will make overall system response to be an unstable one. Problem 4 Different kinds os stabilities are :BIBO Stable, Marginally Stable, Conditionally Stable, Uniformly Stable, Asymptoticly Stable Problem 5 When the poles of the system in the complex S-Domain exist on the complex frequency axis (the vertical axis) ,the system exhibits oscillatory characteristics, and is said to be marginally stable. A marginally stable system may become unstable under certain circumstances, and may be perfectly stable under other circumstances. It is impossible to tell by inspection whether a marginally stable system will become unstable or not..

Why is Inflow and Infiltration (I/I) an issue for wastewater treatment plants? Explain in terms of what causes it, the sources of I/I, and its impact on hydraulic capacity and treatment efficiencies at wastewater treatment plant? Solution Infiltration is due to the excess water that sometimes seeps, trickles, or flows into old or damaged collection systems from the surrounding soil. Inflow is due to additional unwanted water that enter collection systems from above ground sources. For example , due to excess rainfall, from private properties Causes: a) Infiltration: 1. poor soil conditions in which sewer lines are laid 2.poor construction materials or shoddy construction and workmanship b) Inflow 1.Poor planing of the sewerage system 2.draining of swamps, wetlands, or low-lying or flooded areas into collection systems through connect i o n s or leaky manhole covers. Effect on plant 1. Due to Inflow and infiltraion, there exists a uncertainity of amount of water is about to enter the waste water plant. Greater than anticipated flow comes to plant 2. As we know waste water treatemnt plant depends on microbial activity, change in loading rate causes death of microorganisms. 3.Increases treatment cost 4.Decrease in efficiency of plant.

Why is concrete such a widely used construction material? Concrete is basically, (fine and coarse), abd paste\" (water and Portland cement) The devolvement of cementing materials traces back to the Egyptians and Romans. In 1824, Joseph Aspdin produced a Portland cement from a heated mixture of and .in 1872 the first Portland cement plant was opened in. A material that reacts with water to form a hardened mass. The chemical reaction between water and Portland cement, that leads to the formation of hardened concrete. A by-product of the hydration reaction between water and Portland cement. The leaching of free lime. Caused by a reaction of chemicals in the mix water with the cement paste, usually leaving a white stain Solution portland cement is from a heated mixture of clay and calcium carbonate cement: it is the material which reacts with water and forms a hardend mass hydration of cement : the chemical reaction between water and cement , that leads to the formation of hardend mass tricalcium silicate C3S : it is the by product of hydration reaction between water and cement compaction of concrete : it increases the density of plastic concrete by expelleing the entraped air water cement ratio : the ratio of mass of water to that of cement in batch of plastic concrete admixtures : any ingredient other than cement , water, or aggregates , that is added to a batch of plastic concrete to impart certain desirable properties to the plastic or hardened concrete flashing: the ability of cemtn to maintain a stable volume after setting.

What is the role of a jury in a criminal case? Is it important or unnecessary ? Can I get a thesis statement for this ? What is the role of a jury in a criminal case? Is it important or unnecessary ? Can I get a thesis statement for this ? Solution ROLE of JURY Juries are seen as playing an important role in our legal system. Juries have been used as part of our legal system for more than one thousand years but it was not until trial by ordeal was done away with in 1215 that they became an integral part of our criminal justice system. In the same yearMagna Carta also formally acknowledged the principle of an individual’s right to trial by their peers. The jury we are now familiar with and whose role it is to “faithfully try the defendant and give a true verdict according to the evidence” is relatively young. It is only over the last 300 years or so that a jury has become established which is as independent as we now see it and which does not have any influence on law making or any knowledge of the defendant. Set out below is the role of juries in criminal cases. Juries are used in trials in the Crown Court. The jurisdiction of the Crown Court provides for the hearing of more serious offences on indictment. The offenders will have first appeared in the Magistrates’ Court and been committed or indicted to trial at the Crown Court. If there is a not guilty plea there will be a jury trial. If a guilty plea is entered then there will be no need for a trial and the Judge will decide upon the appropriate sentence. The jury is randomly selected from persons entered on the electoral register and they must not be involved in any way with the case. They are required to make an informed decision about whether the accused is guilty or innocent. The jury is told by the trial judge that they must base their decision upon the evidence put before them during the trial and not upon anything else, including things said outside of the court or anything they may have read. The jury must therefore listen to the evidence but their role may also include being made aware of physical exhibits and photographs and in some complex cases may include accompanied visits to crime scenes. Towards the end of the trial, and once all the evidence has been presented by both sides, it is the job of the trial judge to assist the jury in their task by summing up the evidence and directing them as to what the law is. After the summing up, the jury are put in the hands of a jury bailiff who is sworn in and made aware of their duties by the trial judge. The jury leaves the court and must retire to a jury room where they are required to deliberate and come to a decision as to whether the defendant is guilty or not. The jury will deliberate in private. Despite any direction by the trial judge about the law and the facts of the case at the end of the trial, one feature of the jury system is that the jury are free to make up their own minds, free from any outside influence and pressure.
