Developing a Sampling Plan

Words: 5476 Length: 17 Pages Document Type: Term Paper Paper #: 16249528

Sampling Plan

Before discussing a sampling plan, there has to be clear and unambiguous definitions of what a sample and sampling are. Despite diversity in the definition of a sample, the best meaning is that a sample could be considered as a subset of a population, with which a researcher would like to use as participants in a given research study (Landreneau & Creek, 2012). According to Deming (1990), sapling is a science, which specifically guides quantitative studies, materials, behavior and the different causes of difference. In other aspects of research such as the qualitative research, sampling could be considered as the art of selecting a part of a population, in a given research area that is a representation of the entire population.

Both the qualitative and quantitative researchers approach their sampling differently. For the quantitative researchers, samples which are selected are those that will give the researcher easy time…… [Read More]

Promoting Fuel Efficient Cars Establishing Green Spaces

Words: 889 Length: 3 Pages Document Type: Essay Paper #: 4937518

promoting fuel efficient cars, establishing green spaces or forestry, random emission testing, and encouraging alternative transportation, walking, and bicycle use. The total cost is $15.5 M.

Fuel efficient cars

Fuel efficient cars not only reduces pollution but I chose it due to the fact that it is also a good option given today's rising gas prices.

Fuel efficient cars come in 2 categories -- electric and water. What this means is that these cars substitute gas -- which pollutes the atmosphere -- with either electricity or water or hydroxyl.

Hybrid cars are healthier for the environment since they combine gas and water (or electricity) producing lower emissions. They also reduce dependence on fossil fuel which is the main source of fuel today.(Future-Method.com)

The trade-offs of fuel efficient cars are first and foremost price. That, however, can be overcome by compelling distributors to lower the price by making it a more…… [Read More]

Crisis Incidents

Crisis Incidents

The last decade has been riddled with crisis on the global as well as domestic scale. Crisis on many fronts have been noticed for instance natural calamities, terrorism issues, scandals, technological issues and financial disarray. Even so, most leaders aren't fully up to the task in terms of leading a company or society, in general, out of a crisis successfully. Experts at the start of this decade went hand in hand to eliminate the Y2K bug, which became the first Internet crisis. On September 11, 2001, the terrorist attacks in New York City on World Trade Center threw U.S. off balance. Next, the Katrina Hurricane struck with full vengeance in the gulf region which tore apart communities as we know it. The Tsunami of 2004 was another tragic event which rendered millions of people homeless. Last but the not the least, the recession of 2008 shutdown major corporations…… [Read More]

Criminal Justice

For Possible Outcome 2, two groups in a population have been subjected to different treatments. One group served as the control group and was not given the opportunity to engage in an educational program that featured the study of human rights violations. However, the group was given course credit for watching a series of films on nature. he second group watched films that dealt with the Holocaust, Darfur, Rwanda, and the famines in eastern Africa. he groups randomly selected from the prison population, but were not randomly selected for the groups. Both groups had been in the prison facility an average of five years. Both groups were surveyed before watching any films, following each film and at the completion of the courses to measure the effect of the film on the subjects' empathy scores using standardized instruments. Mean scores of empathy ratings were charted below, with the blue…… [Read More]

Bio-Statistics Research Activities Whether Clinical Trial Based

Words: 2419 Length: 5 Pages Document Type: Term Paper Paper #: 3118141

Bio-Statistics

esearch activities, whether clinical trial based, experimentally designed, or product oriented, must exhibit and command interest, enthusiasm, and passionate commitment. To this end the researcher must catch the essential quality of the excitement of discovery that comes from research well done. The first step in the attainment of the desired research goal is to develop a scientific approach toward that which is being investigated. A requirement within the scientific approach best-fit format that is oftentimes misunderstood, and consequently wrongly applied, is that of sampling.

In a rather philosophical approach to sampling Ohlson (1998) states that sampling is " ... But part of the whole. Check to make sure I fairly represent my larger connection " (p. 27). With these words Ohlson is informing the research enthusiast that sampling alone can skew testing results, infuse uncontrollable error into statistical processes, and violate the empirical premise under which the research investigation…… [Read More]

However, due to the lack of a pre-test procedure, it is impossible to assess whether the treatment had any effect in the sample at all. In the one group pretest posttest study the variable under study is measured among the sample prior to the treatment, to get the baseline figures, and then measured again among the same sample after the treatment to be compared with the baseline figures. Nevertheless, the results may not be conclusive that the change was effected by the treatment or some other unknown variable. Meanwhile, the static group comparison study compares the post-test results of two samples (one with treatment and one without treatment). However, just like in the one shot case study, the lack of a pre-test for both samples makes it impossible to conclude whether a change has occurred or not within the groups.

As random noise is introduced in the study which would help estimate the responses in the sample, the result is more error will be accounted in the study. In effect, some modifications of the true responses may not estimate statistical values accordingly, which then, as explicated earlier, leads to erroneous development of findings/conclusions in the study.

And since we are just estimating the actual responses, the results become less efficient and less reliable. It becomes less efficient because the difference to the true effect of being studied will be greater (greater standard error), and data results become less reliable that the results generated using the random noise will not have a truthful description of the population.

The data will still be useful for the public health purposes. Identifying this white noise would help the researcher control these variables in such a way the true effects of the relationship will be…… [Read More]

First, can the research be performed safely on the subject? In some cases, the answer to this question may be no, but the research still be justified, if the possible benefits of the research outweigh the risks to the subjects. In this study, there is no safety danger to the subjects. Second, the researcher must attain informed consent from the research participants. It will be easy to obtain this consent, which can be done in writing, prior to having the subjects participate in the study. Informed consent does not have to describe the nature or purpose of the research, but it does need to inform the subjects of the risks and benefits of the research, any possible dangers, and the subject's ability to opt-out of the research. There are no inherent risks in this project, therefore the subjects will be informed that there are no inherent risks in this project.…… [Read More]

Left Prefrontal Cortex Hobbies and

Words: 7502 Length: 25 Pages Document Type: Term Paper Paper #: 90555739



In short, the left prefrontal cortex is intimately connected to the cingulate cortex, the source of attentional ability (e.g. Kalish, Wiech, Hermann, & Dolan, 2006), whilst simultaneously serving as site for happiness. The hypothesis of this essay, therefore is, that the greater the span of attention accorded an activity, the more positive and more intense the level of serenity experienced.

Although Csikszentmihalyi has conducted research on 'flow' and shown that the experience of flow associated with mindfulness and attentionality has been identified as the highest level of well being (Csikszentmihalyi, 2000), little if any research seems to exist on the connection between hobbies and serenity. It may be assumed that hobbies indicate a sense of flow, implicating mindfulness or attentioanlity, therefore, as per the left prefrontal cortex, sense of pleasure and serenity should be sharpened and participants should feel more serenity. Hobbies, however, are a huge field and their spectrum…… [Read More]

The searches take about fifteen minutes each, and added up, number millions of hours of police time spent conducting these Stop and Frisk searches, making the practice a core part of NYPD police training and street policy, and not simply a seldom used law. Another startling fact is that 88% of those who are stopped are not at all guilty of any crime, but are still forced to submit to the police officers conducting the search for the duration of the search, and cannot bypass the search under any circumstances. This means that the police are spending the vast majority of their time not catching criminals, which may seem like an inefficient method.

The NAACP, a political group representing African-Americans, has come out against the Stop and Frisk law because of statistics published by the NYPD that show that young black men are targeted at much higher rates for random…… [Read More]

Statement of Purpose for a MA in Communications

Communications -- Personal Statement

Say the word 'communications,' and immediately people think of the written or the spoken word. They think of a page of newspaper, a conversation with a friend. But corporate communications encompasses so much more than merely the verbal exchange of ideas.

Corporate communications is kinesthetic. Through my work at my current place of business, Alcoa I communicate by email to all Alcoans worldwide, regarding the Earthwatch program, including its guidelines and the application process. Earthwatch expeditions are hands-on efforts designed to add to the knowledge of Alocan personnel to give them personal knowledge of the different needs that must be met to build a sustainable future. My communication efforts for this program are personal as well as technical, and facilitate the communications process between employees on a personal level, and for the fifteen individuals ultimately chosen to become a part of the program, on a physical…… [Read More]

In other words, when the total number of people characterized by each variable (or stratum) oscillates within the population, to the researcher would choose the size of each sample for each stratum according to the research requirements. uch a choice is prejudiced by the probability of obtaining an adequate number of sampling units from each stratum within the final sample. As a rule, disproportionate stratified samples are used either to compare two or more particular strata or to analyze one stratum intensively (Creswell, 1994). Therefore, when researchers use a disproportionate stratified sample, we have to weight the estimates of the population's parameters by the number of units belonging to each stratum. In this sample, weighting strategies were not performed in the original data.

Once researchers have defined the population of interest, they draw a sample that adequately represents that population. The actual procedure involves selecting a sample from a sampling…… [Read More]

Point estimates summarize the sample by a single number that is an estimate of the population parameter. An interval estimate is a range of values within which the true parameter lies with higher probability. In any estimation problem, we need to obtain both a point estimate and an interval estimate.

Release of Information

A Quality Assurance Indicator and Process for Measuring the Accuracy of Release of Information Requests

According to James F. Keenan (1993), questions about the accuracy of releases of information have assumed increasing prominence in several areas recently, such as the Persian Gulf war, the physical- and mental-health histories of public individuals, the identification of rape victims, and the threat of AIDS. The debates that have resulted have largely been guided by an important insight: the responsibilities that have been entrusted to particular professions contribute to the determination of whether release of information is considered right and proper. Ensuring such "right and proper" releases of information means having in place a system whereby quantifiable aspects of the underlying processes can be periodically reviewed to determine how well it is working. hile the function goes by many names such as quality control, total quality management, and others, the healthcare…… [Read More]

Predictive Policing Compare and Contrast

Words: 638 Length: 2 Pages Document Type: Research Paper Paper #: 57825677

The NY Police department has a regular CompStat meeting so that policing actions are relevant and make use of the most current data (What is CompStat, 2013, University of Maryland). "Contrary to the reactive policing model, the CompStat model strives to deploy resources to where there is a crime problem now, as a means of heading off the problem before it continues or escalates. As such, the tactics should be deployed in a timely manner" (What is CompStat, 2013, University of Maryland).

Feedback: Another important reason for frequent meetings is that they provide consistent feedback as to whether the tactics have been effective. CompStat is a self-critical, not a self-congratulatory model. "Problem-focused strategies are normally judged a success by a reduction in or absence of the initial crime problem. This success or lack thereof, provides knowledge of how to improve current and future planning and deployment of resources" (What is…… [Read More]

limitations of an evaluation are that the evaluation is biased in one way or another. Researchers guard against this by using reliability estimators. Each of the possible four reliability estimators has certain advantages and disadvantages. For example, inter-rater reliability is one of the better methods to estimate reliability when measuring an observation. For an evaluation it is better to use the reliability estimator of test-retest. This reliability estimator can be administered to the same test or a similar sample from different occasions. This approach assumes that there is no substantial change in the construct being measured between the two occasions. The amount of time allowed between measures is obviously critical. Measuring the same thing twice so that the correlations between the two observations are compatible depends partly on elapsed time between measurement occasions. The shorter the time gap, the higher the correlation; the longer the time gap, the lower the…… [Read More]

Words: 375 Length: 1 Pages Document Type: Term Paper Paper #: 11651778



In addition, after the Kansas City Patrol Experiment, the police department noted that it was going to develop a directed patrol system to help control and prevent crime in the city. This was a direct result of what the study found, that routine patrols did not help deter and prevent crime, and that other patrol methods, such as random or direct patrols, were better at deterring crimes, especially in certain hot spots in the city. Thus, the study showed that policing can have a positive affect on a city's crime rate, and it also showed that effective community involvement, combined with direct patrol, can be a serious deterrent to crime, especially in areas of known and continued criminal activity.

The ordering is based on an arbitrary scale that holds no significance besides describing it's obvious qualities.

Nominal Data: Nominal data is information that is organized by name. There is no value in this type of data other than its descriptive use.

Discrete Data: Discrete data is information that needs specific beginning and ending points. Certainty is a required quality of this type of data. Discrete data is information that can be counted.

Continuous Data: Continuous data is information that can be taken from a scalar measurement. Continuous data can be recorded at many different points and can hold any numeric value.

Restraining the Elderly

Project Management

The Project Management path for this research proposal will follow the path of quantitative research in a 'quasi-experimental' environment. Adhering as closely as possible to quantitative experiments designed to establish the causal factors or interdependent links between grouped variables, the researcher will follow a natural course of progression in administering dependent and independent variables, designing the sampling set, determining the optimal time(s) and location(s) for conducting the research, developing the measures and instruments necessary for evaluation of non-empirical evidentiary conclusion (i.e., the thought processes and reasoning of medical staff), measuring the response to education and procedural methodology, documentation to include evaluation materials, response forms, and restraint logs, preparing the education program, delivering the lectures, and evaluating the results in change or lack of change in care providers attitudes toward patient restraint.

Information Technology IT Security and Design

Non-discretionary controls means than there is mandatory access control. In this type of system, security is enforced by a strict set of rules that creates a hierarchy of permissions that users cannot override. Essentially, this type of system is meant to hinder insider users from actually working against the system. Users cannot access crucial internal information as to become spies, thus they cannot see the internal designs of the system to stop leaks such as selling internal designs to competitors, implanting spyware or other malicious software, making critical errors that would injure the system, or access sensitive records that can be leaked to outside sources.

According to the research traditional UNIX is not non-discretionary, but rather a version of a discretionary ACL. In this, there are options as to what users have access to sensitive security information from within the system design. Unlike non-discretionary systems, typical UNIX systems categorize users…… [Read More]

Phenotype How Variations Arise Within a Phenotype

Words: 1091 Length: 3 Pages Document Type: Essay Paper #: 81307836

Phenotype

How variations arise within a phenotype?

Phenotype is the specific characteristics that are displayed by the organism. Phenotypic variation is a prerequisite for evolution due to natural selection, thus without the former, there is no latter. Qualitative traits are traits that show a difference between phenotypes like skin color, sex, and eye color. However, such descriptions are controlled by a small number of genes so environmental influence on these traits is low since it involves the genetics of individuals. Quantitative traits are traits that exhibit a continuous range from one phenotype to another. Therefore, there is no difference between phenotypes and are usually influenced by several gene pairs while the environment has a significant influence on the trait. This type of trait involves the genetics of populations. It is a combination of genetic and environmental factors to produce phenotypes that blend into each other. Phenotypic variance or VP is…… [Read More]

One of the additional oversights in the Proposed Consent Decree is that it does not address the sensitive matter of cell searches of two-person cells that are focused on one inmate. The cell search conducted by Officer Anderson and Sgt. Belker was conducted in an attempt to locate contraband cigarettes that had been sold by Joe Johnson; however, they were still able to search all of Jack Jones' materials. The Proposed Consent Decree is under-inclusive in that it does not make any mention of protecting the inmate who is not the target of the cell search. As it stands, it is still possible for the cell search to be conducted under the premise of implicating one of the inmates while instead focusing on a separate inmate.

Compstat -- Crime Fighting Information

Words: 941 Length: 3 Pages Document Type: Case Study Paper #: 60382414

For example, using predictive policing will likely be at odds with many of the organizational cultures found in traditional police forces in many cities. Furthermore, different objectives may also take precedence over the use of COMPSTAT systems such as political goals as well as the ability for policing organizations to provide the needed resources to take advantage of a COMPSTAT system.

The various COMPSTAT systems can take various inputs, such as historical data, weather, or political events, and process these inputs to generate various sets of "hotspots." These hotspots can be updated daily and reflect the most likely time and space estimates of where crime is more likely to occur given the various factors that are presented to the algorithm. The outputs may represent a location and a time in which police officers should patrol given the likelihood of a crime occurring at this output. The system then can keep…… [Read More]

Validity and Reliability

Types of Validity

According to Trochim (2007), there are six different types of construct validity. Construct validity pertains to the accurate reflection of the operationalization's construct within the conclusion. Of the six types, Trochim (2007) divides them up to translation validity -- which depends on the definition of the construct and the checks against it -- and criterion-related validity -- which applies one's theory of construct and examines the proper behavior of the operationalization. The two translation validity types are thus: face validity, which views an operationalization solely on its face value; and content validity, which juxtaposes operationalization with the content domain of the construct. The four criterion-related validity types are thus: predictive validity, which uses prediction to evaluate operationalization; concurrent validity, where operationalization is gauged in its being able to distinguish between two similar groups; convergent validity, a gauging of how similar an operationalization is to…… [Read More]

(a) the probability of randomly picking two men over 35 from the sample

The sample consists of both men and women, however the question does not delineate segmentation by gender in regard to men vs. women, but solely requests "from the sample" the possibility of selecting men over 35 years of age each draw. Therefore the equation is:

Men over 35 years of age total in the sample.

121 participants total in the sample

239 = P of men in sample

Percentage of men over 35 in the sample 23.9%

Each draw is discreet with a 23.9% chance that a man over 35 years of age will be selected on random selection each time.

Brady-Amoon's and Fuertes' Self-Efficacy Self-Rated Abilities Adjustment

Brady-Amoon's and Fuertes' "Self-efficacy, self-rated abilities, adjustment, and academic performance." This research study had five different hypotheses, all of which were interrelated. All of these hypotheses were fundamentally related to the research question of the study. However, there was a degree of ambiguity in the phrasing of hypotheses five, which states "Self-efficacy, self-rated abilities, and adjustments will be positively associated with college students' academic performance, above and beyond prior academic performance" (Brady-Amoon and Fuertes, 2011, p. 432). The reader is able to discern the meaning of this hypothesis. However, the reference to "above and beyond" is not a clear way of stating that the effects of the constructs of self-efficacy and self-rated ability on adjustment will contribute to improved grades from previous academic efforts. If the authors intended some other meaning aside from an improvement in academics, then they should have stated this fact in some other way. The first…… [Read More]

The exam though it's validity as a barometer for academic preparedness for higher learning is contested, is a means of examining the factors which have been shown to be directly related to the outcomes seen with this strategy. Block scheduling has been shown to correlate directly to mathematics, language, and critical thinking in terms of improving scores. Also, the application of this evaluative comparison across a variety of students and academic settings may resolve the existing questions regarding the relative failure of an otherwise successful technique to raise writing skills. The test will be administered at the conclusion of each trial period in the fashion it would be administered in its intended use. The scores of each student will be compared with their previous score. The overall bell curve of scores between conditions will also be compared as a means of determining both specific and general efficacy.

This may color their judgment I regards to any negative assertions. However, it must be remembered that as teachers their bias should always be towards the student, which in this case will be a positive impact on results.

5. How could validity and reliability be established for this kind of survey?

Certainly an alternate control group could be established with a random selection of teachers who are outside of the criteria used for this survey. This would help to further understand and deviance between norms and establish more validity and reliability for the final outcome. Number and blind referencing would have also added some validity to the results

Criminal justice is seen as the practices, system and the concerned government institutions that are focused on implementing social control, participating in crime mitigation and sanctioning the law violator by imposing penalties and rehabilitation programs. It covers the private sector, the pubic sector, NGOs, state and the local governments as well (Oregon Laws, 2007). To handle effectively such a wide spectrum of departments with professionals without a chance foe making the wrong interpretation of the law once needs to be well equipped with the legal terms.

Words: 659 Length: 2 Pages Document Type: Term Paper Paper #: 75231484

Natural selection is the very efficient and predictable means of evolution by which a species adapts to its environment, that results in evolutionary change as individuals with particular characteristics have a greater survival or reproductive rate than others in a population, and these genetic characteristics are then passed on to their offspring (Natural pp). In other words, natural selection is a consistent difference in survival and reproduction between different genotypes in what is referred to as reproductive success (Natural pp).

Although Charles Darwin's book, On the Origin of Species by Means of Natural Selection caused much ado when it was published in 1859, science now accepts that evolution is indeed a fact, and that natural selection effectively explains how adaptive evolution takes place (Natural pp).

There are two requirements that are essential in order for natural selection to occur (Evolution pp). One is that there must be heritable variation for…… [Read More]

Robert O'Connell's The Ghosts of Cannae is a narrative history for a general audience, based on ancient sources like the historians Polybius and Livy. It describes the invasion of Italy by the Carthaginian armies of Hannibal during the Second Punic War and the battle of Cannae on August 2, 216 C in which the Roman armies were surrounded and annihilated. One of the bloodiest battles in history, nearly 50,000 Romans died that day and 20,000 were captured and sold into slavery, compared to Hannibal's losses of 6-8,000.[footnoteRef:1] Although the Romans were temporarily demoralized by this immense defeat, they rebounded and eventually pushed Hannibal out of Italy by using a guerilla warfare strategy under Fabius Maximus. In the end, Hannibal went down in history as the type of commander who "won…… [Read More]

Queues v System Dynamics

In a system there are different entities that are flowing into and accumulate in stocks then they flow out sometimes into another stock. This is just the same as items in a queue or waiting line. However there are some aspects which are different from queue when compare to systems dynamics. Queues are different from the items that are flowing in and out of stocks as characterized by system dynamics.

System dynamics construct normally allows for modeling of continuous events and bringing in system feedback. System dynamics is thus a methodology that is used in the understanding of how systems work over time. There are two types of systems the open and feedback systems. An open system is one that takes inputs and produces an output from them which does not have any impact on future inputs. On the other hand a feedback system is one…… [Read More]

Six Questions & Discussion on American Politics

Constitutional Convention

During the U.S. Constitutional Convention of 1787, two primary plans were forwarded that shaped the development and discussion at the convention that would forever impact the shape of American politics. The first plan, the Virginia Plan, introduced by Governor Randolph, was an effort to simply revise the existing Articles of Confederation. It was characterized by three major points: the structural exclusion of states from elections and representation at the national level, reductions of powers to individual states, and the abandonment of the some national features of republicanism like institutional separation of powers. The Virginia Plan was countered by two alternative plans, and a division at the Convention: the New Jersey Plan that believed the Virginia Plan went too far in affording power to the national government, and the Hamilton Plan that argued the Virginia Plan didn't go far enough (Lloyd).…… [Read More]
