sampling methods that can be used in quantitative research. The first is simple random sampling. This method allows the researcher to get a truly representative sample of the population, free from any bias. Whether simple random sampling is easy or not depends to some extent on the nature of the population. Simple random sampling does not involve targeting any sub-grouping within the population, but it does deliver a more globally representative sample.
Another method is stratified sampling, wherein the researcher targets specific sub-groups. An example of this would be using demographics to break down groups. Marketers commonly use stratified sampling to understand how specific demographics respond to their products. A company might use simple random sampling, but if it wants to test a specific ad campaign for effectiveness in a target demo, then it would use stratified sampling in order to ensure that all members of the sample are within…

Bluegill Fish Populations: Sampling Methods
Field research can often depend on the quality and reliability of the equipment used to record samples and observations. If researchers fail to understand their sampling measures and any potential limitations they present, the end result of the data collection and observations may not have the validity required to make realistic conclusions about the population in question. Such is the case for studying fish populations, as different collection methods can skew the size and species of fish observed within a given sample area (eynolds & Simpson, 1978). This current survey explores two sampling methods, trap-nets and electrofishing in order to highlight the potential limitations both show and to determine which of the graphs represent each method. Ultimately, Gear B represents the electrofishing method because of the larger numbers of smaller fish, while Gear A represents trap-net methods because there are relatively no smaller fish present…

eimers, 2015) determined that sampling methods have proven to be a very efficient an intuitive method of understanding different properties as they are presented in research. Sampling methods for this specific study will be somewhat constrained based upon the fact that the target population will be derived from a small community facility located in Las Vegas, Nevada. Additionally, the sampling method must concern itself with the fact that the researcher is attempting to evaluate qualitative results and according to eimers (2015) qualitative results that are obtained from sampling methods should be considered with caution (p. 1). It is expedient therefore that the researcher choose the correct type of sampling methodology to achieve the best possible results. In this regard, this study looked at a variety of sampling methods and determined that a modified convenience sampling would likely work very well.
Convenience sampling allows the researcher to work with a population…

There are a number of methods that can be effectively used to gather data in order to ascertain thesis or answer research questions. Determining which methodology to use is at the behest of the researcher and should be determined as part of the overall design of the study. In order to gather valid and reliable data, sampling methods such as cluster, quota, simple random, systematic, stratified, non-probability and probability, and diversity sampling have all been created, and effectively used, to assist the researcher in his/her endeavors. Dos Santos and Beck (2015) found that regarding sampling methods "comparing the performance of several techniques over several problems are rarely found" (p. 624). Since a performance comparison would take a lot of time and effort to complete this study will discuss a few of the methods that are being considered for this study only. The discussion will describe the technique being…

The first study of focus regards perceptions of news media bias and how individual and interpersonal factors affect those perceptions. The sampling method used in this study is non-probability. The researchers worked in conjunction with an international marketing company. The company contacted a massive quantity of people via mail inquiring for participation via mail and via telephone; they had more than 500, 000 participants. The researchers and the international marketing company solicited people based on census data so as to reach intentionally reach & sample a diverse population of participants. They collected data using surveys and questionnaires. The authors were concerned with drawing participants across levels of income, gender, race, and marital status. They made more than one adjustment to their sample group before sending out the questionnaires. They used the census data to draw on populations across age, population density and household size.

In frequency control, the type of quota purposive sample being employed in this example, the surveyor would attempt to get a sample that comes close to the known percentages in the population (Cooper & Schindler, 2008). With frequency control, an exact sample is not required, only that the percentages surveyed are close to the known percentages in the population.
One of the weaknesses of quota purposive sampling is that the variables used to define a population may not be representative of other variables under study (Cooper & Schindler, 2008). The researcher may find that freshmen do not represent the important variable that is being researched, for example. Another weakness is in the data used to identify a demographic. That data could be flawed, outdated, or inaccurate, and as a result the researcher might not get an adequate sample (Cooper & Schindler, 2008). Still another weakness is the researcher's inability to…

Social Network Survey
Draw a sample
The sample for this study utilizes non-probability sampling techniques. Unlike probability sampling, nonprobability sampling does not use random selection (Trochim, 2006). andom selection is rarely used in qualitative survey research as the population will have been selected for specific purposes and often a certain level of attribute representation is desired in the sample for purposes of analysis. Because distinctions between the responses of survey participants from small businesses and medium business are important, individual surveys will be employed.
A series of processes is used to identify and obtain a sample: those processes are together referred to as the sampling plan (Trochim, 2006). The sampling plan for this study uses a purposive sampling format. The sample unit from which the eventual sample will be drawn is commonly known as the sample unit (Trochim, 2006). In this study, the sample unit consists of local small and…

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…

In the second half of the research study the same set of potential employers was surveyed using a vignette method. The vignette described the scenario of applicants who matched the (tester) applicants. The employers who were screened by asking for the person in charge of hiring at the place of business were then asked to respond to the scenario by answering questions regarding if they would or would not hire or consider hiring the applicant in the vignette. Data was collected utilizing the responses to the survey questions, which avoided direct racial comparisons but simply stated the race of…

The Nursing esearch article "Effectiveness of an Aspiration isk-eduction Protocol" addresses a proposed method to reduce the risk of aspiration in critically ill patients through a three-pronged intervention strategy. The intervention strategy components include "maintaining head-of-bed elevation at 30 degrees or higher, unless contraindicated; inserting feeding tubes into distal small bowel, when indicated; and using an algorithmic approach for high gastric residual volumes" (Metheny, Davis-Jackson & Stewart 2010: 1). It used a two-group quasi-experimental design of critically ill, mechanically ventilated adult patients receiving tube feedings. 329 were in the control population, 145 in the experimental group (Metheny, Davis-Jackson & Stewart 2010: 1). The patients were all drawn from the same five ICUs at a Level…

Sampling Size: Qualitative esearch
The aim of qualitative research is to ensure that the population in question is studied with sufficient rigor and above all sufficient depth to yield meaningful results. "There is a point of diminishing return to a qualitative sample -- as the study goes on more data does not necessarily lead to more information… qualitative research is concerned with meaning and not making generalised hypothesis statements" (Mason 2010:8). The advantage to large sampling sizes is that they are more representative as a whole and are less likely to be thrown off by anomalies: "for qualitative studies, where the goal is to 'reduce the chances of discovery failure,' a large sample size broadens the range of possible data and forms a better picture for analysis" ("The importance of a quality sample size," 2013, Unite for Sight). In the process of qualitative research, when a small sampling size is…

There are sampling methods that are still under the quantitative paradigm but utilize non-random sampling to collect data from samples that are either too expensive or logistically difficult to select if random sampling will be used instead. These sampling methods can be convenience, purposive, quota, and snowball sampling (Babbie, 2003:211).
Convenience sampling is a non-random sampling method used when the goal is just to achieve the target sample size of a specific group for the study. No other criteria are set except for the kind of group being targeted and sample size that needs to be achieved. Purposive sampling, meanwhile, specifies characteristics of units that will be included in the sample. These units could be extreme characteristics of each other, or maybe only units from the extreme end of a characteristic spectrum are needed. The objective of this sampling method is to include units of a specific type or a…

In order to study career aspirations, a survey of fifteen students was conducted to determine what level the student expected to achieve as their highest level. The students polled were all business students. The unit of analysis was scalar, with the options reflecting hierarchical levels within a corporation. The results of the survey were as follows:
These results show that business students have a wide range of aspirations and expectations for their careers. While some see themselves on a path to executive-level leadership, others see themselves slotting into middle- or upper-level managerial positions as their apex. None of the business students surveyed felt that they were likely to end up in a non-management role. Because of the desire to create scalar units of measurement, the question did not distinguish between these levels and entrepreneurship. So the size of the company…

A Comparison of Methods for Toxin Exposure Measurement: Personal Exposure v Colorimetric Tubes
Several incidents in the past decade have created an increased attention to the issue of toxin exposure level measurements in both the public sphere and amongst security and emergency response agencies. The need to accurately measure the presence of a variety of air-borne and other toxic substances in specific environments in an incredibly rapid manner can be an issue of truly vital importance in emergency situations, and the measuring of exposure levels for certain individuals -- especially first responders and other emergency response personnel -- is also key to an effective yet careful management of events involving the release of toxic substances. This has led to increasing research in the area of toxicity measurements, and an investigation of the best practices for rapidly and accurately measuring exposure.
This paper will present a brief overview of…

Alignment helps keep both qualitative and quantitative research studies cohesive, meaningful, and valid. The purpose of the study and its implications for policy or practice should be aligned with the research questions, design, and method. Research by Forster, Grigsby, Unger, et al. (2015) illustrates the concept of alignment in a quantitative study. The research focuses on the links between exposure to violence in the community, social ties with gangs or gang members, social self-control, and aggressive behavior. Based on prior research, the authors hypothesize that exposure to violence in the community would be associated with aggressive behaviors. The authors also hypothesize that having friends or family members in gangs was positively correlated with aggressive behavior, and that lower levels of self-control were also correlated with aggressive behavior. All of these hypotheses have the same dependent variable (aggressive behavior exhibited over the past week). These hypotheses and related research questions are…
In the "hard-core" sub-genre of hip-hop, one sees a much clearer emphasis on street and urban authenticity -- rather than on sampling. For N.W.A., hip-hop is an expression of lived life -- a kind of militant message passed down to urban blacks from men like Malcolm X
But not all hip-hop comes from such types. The Beastie Boys are an example of hip-hop artists who thrive on a different message. Much of their music is centered on adolescent/teenage angst -- white suburban kids enraged by suburban living, but moved by urban beats. They inter-mingle their own white perspective with samplings from an assortment of other artists -- thus making their mark on the hip-hop scene. Their aggression appears to be real, like 50 Cent's -- even if it is different in its source. The Beastie Boys are, of course, legends in hip-hop -- but Mickey Hess denies that their authenticity…

Quantitative research uses survey, and questionnaires to collect data. Through quantitative analysis, a researcher is able to correlate mass data to the research findings. Despite the benefits identified in both quantitative and qualitative research, the paper identifies some shortcomings in both research methods. To address these shortcomings, the paper proposes mixed methods that involve combining both quantitative and qualitative research.

Standard deviation is a measure of how far the data is spread from the mean, and can be used to assess the accuracy of the sample mean.
Type I errors are improper rejections of the null hypothesis.
Type II errors are failures to reject the null hypothesis hen it should be rejected.
Level of Significance measures the likelihood of committing a Type I error.
Power analysis measures the risk of committing a Type II error.
Regression analysis measures the relationship between two groups, and can be used to compare separate groups or the same group after an intervention. There are several ways to perform regression analysis.
Analysis of variance (ANOVA) measures the variance observed in groups of data and works to attribute observed variances to specific observed variables. There are different tests used to perform analysis depending on the type of data available and the desired information output.
Another instance in which random sampling is not important is when a researcher is conducting a qualitative study. In qualitative studies, depth of information from selected units of analysis is given more importance rather than the number and representativeness of the target group or population. Thus, for a researcher conducting in-depth interviews of household mothers (for example), the characteristics/selection criteria set in identifying the target group (household mothers) are more important than the randomly selecting participants/members of the target group, which could result to household mothers who do not fit the criteria or characteristics set by the researcher. In effect, the type of information that would be generated from randomly sampled household mothers would not be as insightful as it would have been to specifically-selected household mothers fitting the researcher's selection criteria.

experimental method, otherwise known as quantitative research or laboratory study, is to formulate a hypotheses, to collect the data, and test this hypotheses according to scientific principles that obstruct, as carefully as possible, bias, and then to analyze this data using statistical measures. The experimental method uses random sampling as part of its discourse.
Practical considerations usually limit the amount of control we have in structuring experiments, for instance we cannot always hope to randomize; we sometimes (more usually) often have to make do with the sample of participants given. This is when quasi-experimentation is employed.

Psychological test or assessment method. "The Substance Abuse Questionnaire -- Adult Probation III
Brief Description of the Test
The recent release of one of the youngest convicted child murders in our nation's history, Lionel Tate, now an adult, into the general population, has highlighted the difficulty of determining if a former prisoner should be eligible for parole. Psychologists have attempted to answer this difficult and subjective question by designing the objectively-assessed test known as "The Substance Abuse Questionnaire -- Adult Probation III" exam. (Risk & Needs Assessment, Inc., 1997) This test was originally designed in 1987 exclusively for adult prisoners eligible for probation to determine the risk of paroling them and assessing their risk to society and has since been updated, in 1997, to include inventories for truthfulness. (Spies, 2003)

(1) How have quantitative and qualitative elements been related? What type of combined designs have been sued? What is the level of integration between qualitative and quantitative aspects of studies?
(2) Why have the authors chosen to prefer multimethod or mixed design to monomethod approach? Do they offer a rationale for their choice? What is the purpose of the combination of different approaches?;
(3) What are the complications that the use of different combined designs brings about?; and (4) How do design characteristics influence the inferences and conclusion the authors draw? (Niglas, 2004)

VIII. Differentiation of Mnemonic and Non-mnemonic Elaboration Techniques
Mnemonic and non-mnemonic elaboration techniques are differentiated by the manner of association of new words with previous knowledge in that: "mnemonic elaboration techniques establish this connection through verbal and visual imagery" however, the elaboration of non-mnemonic techniques makes this connection through use of semantic characteristics and may be through the organization of a list of scrambled words known as the 'ordering method' or through generation of sentences with the target word in a manner that the inference of the word can be made by the sentence or the 'sentence writing method'. (Sagarra and Alba, 2006, p. 231)
Furthermore, the connection can be made through construction of a diagram displaying the target word's semantic association known as the…

Abortion After Prenatal Testing
Methods of Prenatal Diagnosis
There are four methods of prenatal diagnosis that is available to women. The first and most commonly known is ultrasonography, colloquially referred to as "ultrasound." A picture of the fetus is developed through the implementation of sound waves. Ultrasound is used to identify abnormalities that are physically apparent such as deformed limbs, defective chest, and heart. During the fourteenth to sixteenth week of the pregnancy, neural tube defects can also be detected (Cassidy & Gentles, 2002). There are other uses such as detecting multiple fetuses and measuring fetal growth.
The second method is Maternal Serum Alpha Fetoprotein Screening (MSAFP). Its primary purpose is to detect neural tube defects by measuring the alpha fetoprotein levels in the women's blood. High levels of alpha fetoprotein can indicate neural tube defects in the fetus. This exam is typically administered during the fifteenth to seventeenth week…

Summary and Analysis of The Forgotten Followers Contingency Model of Leadership and Follower Self-leadership by Seokhwa Yun and Jonathan Cox and Henry P Sims Jr.
This study was conducted to evaluate the impact of leadership and follower attributes on follower self-leadership. The abstract provides a clear summary of the study in terms of its purpose, research methodology, findings, implications and limitations of the study, practical implications, and originality/value of the study. As shown in the abstract, the purpose of the study was to assess the effect of leadership and follower attributes and follower self-leadership. The researchers found that the impact of leadership on follower self-leadership was dependent on follower need for autonomy.
As part of conducting the study, these researchers introduce several concept beginning with the idea that, “Not everyone wants to be empowered!” The statement basically highlights the two major differences in people’s response to self-leadership opportunities i.e. some people…
Sampling and Collecting Quantitative and Qualitative Data
Probability sampling represents the best strategy for selecting research participants
There are many ways of gathering information from a population using the qualitative or the quantitative approaches. Probability sampling is indeed the best strategy that a researcher can use to select participants from a population. There are many reasons to support this position as below discussed. Probability sampling can be understood as the sampling technique that takes a small sample from larger populations using one of the methods under the probability theories. In order for a participant to be selected a random method of selection must be used. The most fundamental requirement in probability sampling is ensuring that every person in the population has an equal and known likelihood of being selected. For instance, where a sample of 10 people is to be selected from a population of 100 people every person in…
employing convenience samplings is some bias in non-representative population. Due to this limitation, convenience sampling is not usually subject to tight sample measures (Bailey, 2009). Convenience samples don't give the representative outcome. If a person needs to extend the targeted population, convenient samples cannot acquire the research there. The normal instinct is to extract from the convenience samples. When using convenience samples, there is the likelihood to handle the results as representational, though they may not be. The outcome of convenience samples is difficult to clone. If a researcher conducts the analysis of a convenience survey outcome by means of a list source, they would often observe dramatic variations in the feedback from the various lists, usually in a manner that would complicate the explanation (Convenience Samples: Pros and Cons, 2010).
Although convenience samples are way better than having no samples entirely, the limitations of the convenience samples must be…

Indeed, as Muntaner (2003) posited in her research, qualitative methods can be included in a dominantly quantitative research design "in situations where qualitative research adds knowledge that would not be available via quantitative methods" (p. 55). Through a mixed-methods design, the researcher can provide better analyses and stronger interpretations and recommendations through balanced strengths of data reliability and validity -- that is, the achievement of "triangulation" in the research study.
IIA. ased on your reading of books such as eaglehole (1993), describe what you know about observational epidemiology as a research approach and compare it to experimental studies. Describe some of the designs within each, e.g., RCT, case-control studies, etc.
Observational and analytical/relational studies provide different results and answer different research questions and hypotheses when compared to the experimental approach. In observation and analytical/relational studies, the highest kind of analysis that can be done is correlational and not causal.

power of statistical analysis is the power to define, interpret, and understanding numerical data which represents patterns in the real world. Without the ability to measure statistical data, the empirical, hypothetical world of educational models would not be able to be checked by actual performance in the absolute. While statistics has applications in many fields, statistical data is possibly the most powerful when used to identify patterns in personal behavior, and other fields of study which do not exhibit direct patterns across a sampling group. For example, mathematical equations govern how a specific metal will respond to different loads, and different conditions. However, there are no direct mathematical equations which govern the percentage of teenage drivers who will be involved in traffic accidents over a period of time. In order to interpret the influential factors over teen drivers, a statistical measurement of actual experience can be undertaken. Through statistical analysis,…
Regarding a linear regression analysis of this relationship, we find that the slope of the line is close to 0.5, and the relationship is a direct linear relationship between the amount of tar in a cigarette and the amount of nicotine.
Nonlinear trends in statistical data can be the most challenging to work with. When non-linear relationships exist, there may be a mathematical relationship which is based on a logarithm, or other multi-factor influence. However, true non-linear relationship, such as the height and weight of a specific person who shops in a given department store may leave the statistician without any relationship whatsoever. Non-linear data can also be the result of data which is being acted on by an artificial, outside force. In this case, the statistician is able to verify the existence of an outside force, and then approach the process of identifying the force.
An example of this situation is the expected relationship between supply and demand, and company profit based on the sales of a given product in the market place. In the early 1980's, the Coleco company produces a product called "Cabbage Patch dolls." The typical lifecycle of a new toy product is one to two years, but Coleco was able to extend the life of their product for four to five Christmas seasons by artificially affecting the relationship between supply and demand. The company had the production capacity to produce 4-5 times the amount of dolls which it shipped to the market during the first three years of the dolls life cycle. This would have produced a typical bell shaped curve, plotting a rising demand, and increasing profits which gave way to a declining demand and declining profits in a short period. However the company did not produce product equal to their capacity, nor equal to the demand. As a result, the company was able to continue a high level of demand, and an inflated retail based on the high demand for an extended period. The result was that the doll stayed popular for almost a decade, and the company was able to reap ongoing higher levels of profits. The longer bell curve, identified by an irregular and nonlinear relation between time and supply and demand was created by the unique marketing strategy for the company.

According to Hickman (et al.) in the 2008 article "The differential developmental pathways of high school dropouts and graduates" from the Journal of Educational esearch, the concern about the gap in achievement between high school graduates and non-graduates has long been a concern of educators and educational policy-makers alike. The peer-reviewed study posed two essential research questions to address the problem of low high school retention rates: first, do differences in the educational development of high school graduates and dropouts exist early on in their elementary school careers and secondly, if differences do exist, "where in time and across which variables do these differences occur" (Hickman et al. 2008: 2). The study attempts to address a 'research gap' in the existing literature regarding the focus on the secondary school careers of high school graduates. Focusing on the problems students encounter in high…

Regarding Data Collection and Analysis
It is possible to use a word processor to analyze qualitative data (LaPelle, 2004), an idea that is appealing because of the implied simplicity and because it is comparatively inexpensive. As I understand it, a qualitative data analysis tasks include the following major steps: Coding and retrieving data; inspection of data to prepare for indexing; creating hierarchies of categories by indexing; review and editing of the theme codes; including face sheet data about individual respondents (if interviews or surveys have been used) through demographic coding; relating the demographic data from the face sheets to the conceptual codes; quantifying the frequency of the instances of the codes; and annotating the text or narrative (MacQueen, et al., 1998) The terminology is a bit esoteric, but the process of qualitative data analysis is iterative so it helps me to think of the data as passing…

Labor Market Surveys In Forensic Rehabilitation Counseling
The article elaborates the concept compensation system for workers in California. The author argues that the opinions of vocational experts should meet standards of motivational satisfaction. This principle operates on the view that operational decisions by the court should focus on upholding the ruling by administrative body in case evidence supports material concerns from the administrative body with a reasonable base of the decision. I agree with the clarification that labor markets exist for some jobs as recommended by the vocational experts although labor market surveys (LMS) must be undertaken to establish substantial evidence. The surveys avail the necessary details involved in the determination of whether employers can consider employees with medical limitations against their current abilities and skills vocational training. Further, the civil cases established through labor market surveys offers invaluable demonstration of the available employment opportunities in specific…
Research into the legalization of marijuana will seek to determine what people's views on the issue are. The population is going to be the entire United States, as we are seeking to determine national views about the issue. The sampling will be done at random, using databases of phone numbers and computer-generated dialing. The operators will only know of and gather non-personal information such as age bracket, gender and state of residence. The major downside to this form of sampling is that many younger people will not be sampled because they often do not have landlines.
Random sampling is the "purest form" of probability sampling in that it is free from researcher bias and is more likely to accurately reflect the total population as a result (StatPac, 2012). Landline ownership is a reasonable proxy for the total population, with the caveat noted above. However, other sampling methods are…

The research in this study is exploratory and descriptive. The study begins with the declaration that this topic of study has been pursued in the past, yet the sampling methods used proved ineffective in defining or describing why less Asian-Americans utilize healthcare services in the United States. This research seeks to describe the problem of little use of healthcare with their study. The research in this study classifies the phenomenon of lack of healthcare service use/participation by Asian-Americans. The research problem is that Asian-Americans are not using the healthcare services available to them for a variety of reasons. The research problem is stated clearly in the first two pages of the study. In this study, there were no listed hypotheses, instead there are objectives. The objectives of the study are:

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…

The trainer will then focus on the steps to be taken to develop new skills. For example, if the trainer wants to talk about motivating, leading, negotiating, selling or speaking, it is best to start with what the learners do well before showing some chart on Maslow's theory, Posner's leadership practices, or selling skills from some standard package that has been develop elsewhere. Many foreign trainers make grave errors because they do not consider the values and beliefs of the trainee's culture. Training must make a fit with the culture of those being trained, including the material being taught, as well as the methods being used (Schermerhorn, 1994).

What is the relationship between age and responsibility?
Age refers to the numbers of years a person has live right form birth till date. Age may indicate the level of maturity of an individual depending on the circumstance a person has been brought up. The age of a person can only be categorized and measured according to figurative values. For instance age can be categorized as follows
a) 0-10years (children)
b) 11-20 years (adolescents)
c) 20-30 years (adults)
d) 30-40 years (old people)
e) 40-50 and above (elderly people)
Responsibility refers to the capability of an individual to handle certain situations the immediately surround him or her. Responsibility reveals the capacity of a person to take care of a given assignment to excellence and perfection. Responsibility can be categorized as follows
a) Very responsible

complexities of doing business in our virtual age, looking in particular at e-commerce but also asking how the presence of e-commerce on the market has affected traditional businesses as well. Once upon a time - that golden age - things were simple. You decided you wanted to grow up to be a bookstore owner. Or a hardware store manager. Or a florist. So you leased a store, bought some books, and lovingly hand-sold them to each customer who flocked to your door and then went home at night to count your money.
Of course, owning a bookstore or a hardware store or a flower shop was actually never that simple. But the picture now is even more complicated as virtual stores have entered the picture. Part of what makes engaging in e-commerce so difficult is that there are no paths that others have trod before one. And the costs of…

MY ROUGH IDEA:
1.To successful launch an e-commerce Web site, the question is not just about if we build it, will they come?" But also if we build it, will they come to purchase and repeat purchase?" A scenario closer to the truth is that many online companies experience disappointment in converting consumers' clicks into purchases. It means attracting a large number of shoppers to the site is not the only ultimate measure of success. The true measure of success should be included retaining customers and converting them into repeat buyers. Positive shopping experiences on the site can help online buyers make an effective decision. It means positive feeling is the optimal experience that consumers will desire to repeat buying online. Therefore, marketers need to create effective Web sites for winning consumer satisfaction. Since Web sites are often the main contact with consumer in the Internet market, a company's Web site elements may include some persuasive components that has imp!
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…

ole of esearch in Social Work
esearch assists in placing social work in its changing political and social context. This implies the ability to define social work's current environment in terms of dynamics like society and politics. esearch assists in establishing a knowledge base and professional status of social work, for example it assisted in establishing evidence-based practice. esearch also assists in analyzing population-based research that identifies people at risk in social work (Leece & Leece, 2010). This is because is assists social workers to understand clients in their social contexts, give voice to clients. Overall, research provides epistemological and value issues that define the nature and purpose of social work.

Banks and Pracht (2008) carried out a quantitative research to investigate the current staffing trends at reference desks of academic libraries. The research is conducted from a theoretical framework perspective asserting that there have been changes in libraries, as services are merged and eliminated, users are taught on information literacy, provision of web-based and online reference databases threatening the traditional reference desk. The researchers' main question is whether these changes are causing a change in staffing patterns for reference desk employees. To investigate this problem, survey questions were administered via the internet to respondents comprising of librarians from 191 academic libraries across the U.S. The study results indicate that of those interviewed, 44% show that there was a decrease in questions asked at the reference desks, which linked…

Describe the role of rigor in nursing research.
The extent to which nursing research methods are carefully and strictly conducted in order enhance the quality of the evidence that the study yields. This is even critical if casual inferences about relationships are of value. In addition, rigor ensures that threats to validity are minimized, assessed and considered during the study.
Discuss three sampling methods for nursing research. Include the positives and negatives of using each in nursing research.
This method entails using available people as study participants. For example, a nurse conducting research of pregnant HIV- AIDS patients relies on convenient sample. The disadvantage of this method is that the available participants might not be representative of the population of interest with regard to critical variables.
This method involves the researcher indentifying the sample strata in a bid to determine the number required from each…

On the job, exposure is to hazardous materials or conditions is related directly to the job activities performed by the worker. As part of the familiarization process know as process management one can become knowledgeable about the workers' job activities and the consequent potential for exposure. In this essay, we will review the OHSHA process step-by-step an explain the procedure for conducting a job hazardous materials analysis (HAZMAT) ("Compliance guidelines and," 2010).
Most integrated sampling methods for gases and vapors that are published by OSHA use active and passive sampling techniques. The OHSHA procedures are examined below for advantages and disadvantages of active and passive integrated sampling methods in the process analysis (ibid).
In the process, complete and accurate written information meeds to be included about the chemicals, technology and equipment that is essential to an effective process safety management program and/or to an effective process hazards analysis. These…

special education from the standpoint of the students' parents. The writer explores the opinions on the accessibility and quality of special education afforded their children in Massachusetts. The writer examines the opinions through the use of research project that is proposed here. There were eight sources used to complete this paper.
For the last four decades the nation has been steadily working to improve the special education system within its public schools. A Supreme Court decision in the 1960's mandated that special education children be given many more services than they had in the past and that they receive that education within the least restrictive learning environment possible. Over the last four decades as these changes have taken place there have been many articles published on the changes, and the success or failure of those changes. Massachussets has enjoyed the cutting edge of special education reform with prototype programs as…

A prediction of the outcomes is not made in the initial development of the research. ather, this appears to be an exploratory study to better understand the issue.
eview of the Literature
The literature included in the review is relevant and recent. The data demonstrates the need for understanding the problem and the importance of the issue to the health and safety of healthcare workers. Although the initial literature review is quite brief, the literature is expanded in the discussion of the results.
The research design is a quantitative methodology utilizing a survey to collect data. Information collected was appropriate given the overall scope and focus of the research -- i.e. exploratory. Although the results provide some insight into the specific survey that was used, pertinent information about the survey has been omitted from the study. This may make replication of the study difficult.

interview techniques. DiCocco and Crabtree (2006) discuss different interview strategies. One is the unstructured interview, a technique that originates in anthropology study. This technique is used when the type of information to be gathered is not known, or is only loosely-defined, because the technique is open-ended. Eliciting insights is a key objective of this type of interview.
A second interview strategy is the semi-structured interview. In this technique, the interviewer is able to "delve deeply into social and personal matters" (Ibid). The group interview can be used with this strategy as well. Semi-structured interviews are commonly used to gain information that might be open-ended in nature, in a group setting, or to learn about someone's life experiences. The focus group is a form of semi-structured interview used in marketing.
A third interview strategy is the individual in-depth interview. This technique is used when the research question is focused, and is…

Procedural igor - the qualitative method and design of the study was appropriate and effective. The researchers described how rigor was maintained in the procedures of the study, and how integrity of the data was preserved through the maintenance of constant responsiveness during both data collection and analysis for the study. It is also described how the researchers maintained objective and critical by maintaining some distance from the data periodically. Therefore, the researchers were aware of potential biases and used these approaches in order to effectively deal with them. The amount of data collected by the researchers was sufficient. It allowed for accurate analysis that yielded meaningful results. Other research studies have utilized qualitative designs for investigations involving asthma (Lyte et al., 2007; Pontin & Lewis, 2009) as well medication adherence, but these did not explore behavioral factors involved in medication adherence in asthma patients.

This will also lead to the finding on whether the kind of offense committed translates to a lengthier sentence on imprisonment and in effect, on the likelihood that the ex-convict will commit the same or a different kind of offense again. Lastly, the researcher is also interested to determine whether the commitment of re-offense, if indeed committed by the ex-convict, changes in level or degree -- that is, whether the re-offense has a greater, lower, or the same level of punishment.
In terms of the research sample, the researcher proposes looking into a sample of ex-convicts who came from the same correctional/prison facility. By sampling a group of ex-convicts from the same prison facility, the researcher prevents data from being tainted with extraneous variables, such as the existence of prison programs, which might influence the ex-convict's reformation during his/her prison term. Thus, when a particular correctional or prison facility is…
