eliability & Validity
For the lay person, the notion of personality is often derived from components of an individual's character or make up that has the ability to elicit positive or negative reactions from other individuals. The person who has a propensity for positive reactions from others is often thought to have a 'good' personality. Conversely, the person who tends to elicit not so favorable reactions from others may be thought to have a 'bad' personality. However, when behavioral and social scientists seek to describe and define personality, the terminology used is far more rigorous that describing simple social skills (Cohen, Montague, Nathanson & Swerdlik, 1988). As such, constructs such as personality traits, personality states and personality types have been studied as a means of provided clinically accurate ways in which to define personality.
Nevertheless, there is no one globally accepted definition of personality within the scholarly literature. McClelland (1951,…

eliability of Test
eliability is defined by Joppe (2002,p.1) as the level of consistency of the obtained results over a period of time as well as an accurate representation of the population under study. If the outcome of the study can be reproduced using a similar methodology then the instrument used in the research are said to be reliable.
It is worth noticing that there is an element of replicability as well as repeatability ff the observations or results. The work of Kirk and Miller (1986,41-42) indicated that there exists three different types of validity in any given quantitative research. These however, all relate to; the extent to which the give measure if repeated, remains constant, the stability of the given measure over a period of time as well as the similarity of the given measurements in a given time period. The work of Charles (1995) focuses on the idea…

eliability and Validity
Trochim (2007) examines validity and reliability in the context of arriving at measures for constructs that firstly measure what they purport to measure. Secondly, the measures do what they purport to do in a consistent manner so that the researcher can have confidence in the measurement and hence the research project is not compromised. The elements of validity and reliability are pivotal concerns to research. esearch thrives in a climate where these are dominant and progressive. Without effective mechanisms to achieve these objectives, the entire research process and the products of research become suspect.
The six types of validity examined by the author are separated into two different components of construct validity. Construct validity is a measure of the success of process of turning constructs into measures. This process identified by the author as operationalization requires that the measures and their underlying construct have a close affinity.…

Having evidence demonstrated over a number of different trials at different schools, each with similar results contributes to external validity. Thus, the trials must all be for universities, as opposed to careers for example, so that the results of those trials are transferable to our university's admissions process.
To ensure internal validity, the admissions test must include a sufficient number of questions (data points) to establish a clear trend. The questions and answers themselves must be free of ambiguity, which could distort the results. Further, the questions and answers must relate directly to the personality attributes that we are attempting to measure, if the results are to be valid.

eliability, validity and norming sample populations play critical roles in the usefulness of assessment instruments used in forensics assessments. These three facets of assessment help to determine whether or not the results the assessment yield is credible. Additionally, they each help to evaluate a particular aspect of an instrument, although there is generally a degree of correlation between these factors.
Validity is simply the accuracy of a test to effectively measure the particular phenomenon that a researcher is attempting to measure. There are different types of validity including construct validity, content validity, and criterion-related validity (ichmond, 2013). These different facets of validity determine the accuracy of an assessment in terms of its construct, its usefulness is appropriately sampling the different components of the construct, and its accuracy in foretelling performance. eliability is the facet of an assessment to provide consistency in its results over time. eliable tests can generally yield…

Importance, Reliability, Collection, and Testing
It is tough to define data. Think of it more like the raw information that when processed and analyzed can give you an understanding of a situation, process or fact. Clearly if data is the first step to information, we must do out best to ensure the accuracy and reliability of data. Let us take a look at what data is used for:
Data can be used to Stimulate new organizational ideas
Improve quality of emergency care and procedures
Draw attention to an issue
Influence legislative and regulations
Provide justification for an existing program

Another disadvantage regarding the validity of the analysis regarding gender was that the results between the two gendered groups were calculated based upon a mean, which meant that one or two respondents with scores could have a considerable effect, skewing the results in one direction or another.
The two sample groups of 59 psychology students and 100 MBA students were relatively small and select as well. Using these populations is also of concern given the degree to which they are relatively homogeneous in terms of the test-taker's backgrounds, ages, and education.

Millon himself stated the test is "not a general personality instrument to be used for 'normal' populations or for purposes other than diagnostic screening or clinical assessments" (Psychological testing, 2009, IPT). The test is only for use with subjects who are already known to exhibit psychopathology and personality disorders. It is best to use to refine a diagnosis that is already supported by other evidence and is not suitable as an initial assessment instrument.
On the orschach, what is the Lambda? What does a Lambda of .80 indicate?
The Lambda is a measure of the subject's openness. Subjects with high measures of Lambda (>1) tend to be resistant to revealing a great deal about themselves. Or, they may try to simplify their psychological issues by ignoring the complexities of life. Subjects with low Lambda ratings tend to have few form-driven responses and show higher tolerance of ambiguity (Ganellen, 1996, p.31).…

6. Positive approach is empirically based and insists that measures must proceed according to strict evidence and their validity must be generated from experimental (or quantitative) research. The advantages are that this accords greater validity and reliability. The disadvantages are that the complexity of human factors is inadequately addressed by the rigidity and inflexibility of the experimental method. The qualitative (or non-positivistic) on the other hand, insists that humans cannot be measured or tested in a laboratory environment. The results are, however, less reliable, and oftentimes more subjective.

Value Engineering and Reliability
Value engineering is viewed in many industries as an excellent strategy for reducing costs, increasing reliability, and improving quality (OM, 1993). It can be implemented in hardware and software; development, production, and manufacturing; specifications, standards, contract requirements, and other acquisition program documentation; facilities design and construction.
Value engineering is a technique directed toward analyzing the functions of a project or product to determine "best value," or the best relationship between reliability and cost. In other words, "best value" is represented by a project or process that consistently performs its required basic function and has the lowest cost.
In this context, the application of value engineering in a construction project can yield a better value when construction is approached in a manner that incorporates environmentally sound and energy-efficient practices and materials.
This paper discusses the important relationship between reliability and value engineering, in an effort to explain…

Inter-rater reliability
Inter-rater reliability is considered the degree to which two or more evaluators of a study agree on its results and outcomes for reliability (Lange, 2011). When a rating system is implemented in a study, its consistency is addressed by this parameter.
It was tested for the reliability of a new clinical examination method called Cognitive Assessment and Reference Diagnosis System (CARDS) for early detection and management of dementia (Suh & Lee, 2003). The method was applied to 70 dementia patients and 34 healthy and control individuals. 22 of the 104 subjects were interviewed separately for checking the inter-rater reliability based on the fact that their responses were blind to each other and were not shared between them. The results showed that CARDS was a reliable instrument for detecting early dementia and its management in patients.

Reliability
a. Dependability means emphasis on the need for researchers to take into consideration, the ever-evolving context within research as it happens (Creswell & Miller, 2000). The responsibility of qualitative research is to describe the changes naturally occurring in the setting as well as how such changes researchers approach the study. To address dependability within a qualitative research study, a person can perform member checking of data interpretation, a pilot test, and a peer review. These techniques allow for accurate assessment of dependability regarding the information collected for the study.
When a person begins qualitative research, to determine reliability and dependability of the information collected, they may perform member checks. “Member checking, also known as participant or respondent validation, is a technique for exploring the credibility of results. Data or results are returned to participants to check for accuracy and resonance with their experiences” (Birt, Scott, Cavers, Campbell, & Walter,…
Adult Learning Assessment
Adult learners comprise one of the fastest-growing segments of students today, and adult learners typically have needs that differentiate them from the younger learner. There is already much scholarship devoted to how the adult student learns new information. This understanding of the different learning styles has been taken into consideration in the design of courses and curricula for adult learners.
However, teaching tools are only part of the equation. Educators must also be able to assess if the adult learner is indeed retaining the information at both a critical and analytical level. Thus, in addition to the development of curricula, Cooledge et al. (2000) discussed the need to develop proper assessment tools for adult learners. In particular, Cooledge et al. (2000) focuses on the validity and reliability of portfolio assessment, one of the most popular tools in adult education.

For example, a test that requires students to make use of vocabulary words only pertinent to certain areas of the country, whether rural or urban (a city child may have never seen a cow, or know that a cow and a bull are the same animal) might result in poorer assessment of that child than is warranted. A Caucasian child might not be asked to describe common Vietnamese foods, but a recent Vietnamese immigrant might be called to do so on an intelligence test.
This is hardly culturally fair in assessing intelligence, even if children who are immigrants or bilingual might benefit from additional resource room help. Remember, even though a bilingual child may need English help, this is not a reflection of his or her general intelligence quotient, even if poor English ability may result in a lower test score on an English-administered test. After all, an affluent child…

Credibility and eliability of Sources of CAM Information:
The identification of the most suitable Complementary and Alternative Medicine therapy to help in treatment of the patient's symptoms is a process that is based on extensive research. The increased use of CAM therapy in the American health care system provides clinicians with a new responsibility of becoming informed regarding the suitability, safety, and effectiveness of various healing procedures that are largely unfamiliar. The research process used to develop the most suitable CAM therapy involves obtaining information based on opinions rather than facts. Actually, there is plenty of research on CAM therapies that are not usually published in the established American medical journals or presented based on the traditions of standard medical research. Therefore, since the health care system requires factual information instead of opinions, clinicians face the need to ensure the credibility and reliability of the sources of Complementary and Alternative…

Monitoring an Aircraft's eliability System:
In the civil aircraft industry, one of the most critical areas is the operational or dispatch reliability of an aircraft. For any airline, the reliability system of an aircraft is very important since its effectiveness lessens flights delays and cancellations. The effective working of this system to achieve its functions also results in greater operational efficiency, customer satisfaction and flexibility. Dispatch or operational reliability is defined as the percentage of scheduled flights that depart without any technical delay that exceeds 15 minutes or a flight cancellation. It's important for any airline to ensure that the reliability systems of its aircrafts are effective since this result in less costs and greater revenues for the airline. The reliability system of an aircraft is largely affected by both technical and non-technical factors with the technical ones resulting from the decisions made by designers. On the other hand, the…

Validity
The types of reliability used consist of test-retest reliability and internal consistency where the types of validity that were used are construct validity and criterion validity (vmiman). The test-retest reliability is an assessment of the similarity of scores on a particular scale over two or more test occasions. The Pearson correlation coefficients are used to quantify the similarity between the scale scores over two or more occasions. Stability coefficients provide an important indicator of a test's likely usefulness of measurement.
Internal consistency is known as scale homogeneity and is an assessment of the ability of the items in a scale to measure the same construct or trait. A parameter can be computed that indexes how well the items in a scale contribute to the overall measurement. A scale is internally consistent if all the constituent item responses are positively associated with their scale score. The most common is Cronbach's…

Discussion 1:
I have used many different types of assessments in my classes in the past. I would use student self-assessment, portfolio assessment, observational (informal) assessment, and formal assessment such as tests, quizzes and exams. I felt that the more varied your assessment methods, the more reflective of the student’s overall abilities the score at the end would be. Student self-assessments allow students a chance to review their work on their own and judge their performance; it promotes active engagement with their work instead of passive engagement with whatever assessment the teacher gives. Portfolio assessments are good because they allow the student to gather the best work over a period of time and see how they are developing. Observational assessment is good for developing a sense of the student’s skills in an informal way, the student’s participation level, the student’s methods of interaction and communication, etc. Formal assessment is good…

The dependent variable examined in this study was the disaster preparedness of trauma centers. The dependent variable was measured using a questionnaire which was distributed to twenty-nine trauma centers in Canada. The medical director of each trauma center was invited to respond to the questions on the instrument. The researchers then employed descriptive statistics to describe the state of preparedness based on measures within the instrument.
The question of validity is essentially does the instrument measure what it purports to measure. The issue of validity in a study has several components that may be separated into categories of internal and external validity. Elements such as face validity, content and construct validity are…

Quality Cost
Quality and eliability
The cost of quality, in the context of management and the business side of operations, is quite different from (though related to) the cost of quality from a consumer perspective. The old adage, "you get what you pay for" is a word of warning or reminder to consumers that higher quality items tend to be more expensive, and thus the "cost of quality" is simply a higher price tag for consumers. For the companies actually producing goods and services, this same perspective might apply to certain materials and equipment procured for use in the production process, but this is only one of many "costs of quality" that business must endure (Accounting for Management, 2012). Factors of time, process controls, testing, correcting mistakes as quickly and completely as possible, and a variety of business- and industry-specific concerns all impact the costs that a company incurs in…

Content-Based Assessments
1) What evidence should be provided that learners have mastered content?
When teachers give content-based assessments, they are measuring how much information students have retained from lectures, discussions, readings and other learning experiences (e.g., homework, projects). In creating a content-based assessment, the teacher must look at all the learning materials and experiences that have taken place during the unit or course of study. The questions that are asked must accurately reflect this content so mastery can be assessed. Teachers have to ask the right questions to give students an opportunity to give the right answers.
2) How would an instructor determine whether a content-based assessment reflects learner knowledge?
Instructors must design test instruments that allow students to demonstrate their content knowledge and also put that knowledge into practice. It is not enough for students to…

eliability and Validity in Psychological Testing
In any kind of academic and professional testing, it is important to obtain at least some degree of reliability and validity. Failing this, the tests cannot be applied for results that are consistent or usable in an academic setting, since they cannot be verified in terms of repeatability or in comparison to other results. In psychology, which is more often than not studied by qualitative rather than quantitative means, it is often difficult to establish reliability and validity, since the specific numbers to do so are lacking. However, there are means to ensure an optimal level of validity and reliability in this kind of testing

Credibility, Reliability and Validity in Fiebert (2004)
The source provided by Fiebert (2004), published in Sexuality & Culture, 8(3-4) and entitled "References Examining Assaults y Women on Their Spouses Or Male Partners: An Annotated ibliography" offers a concise overview of a broad sampling of literature on the subject of female-on-male spousal assault. At its outset, the study indicates a sampling of 155 scholarly investigations, 126 empirical studies and 29 reviews and from this selection of literature which is outlined in brief qualitative passages concludes "that women are as physically aggressive, or more aggressive, than men in their relationships with their spouses or male partners." (Fiebert, p. 140)

Validity & eliability eview
The author of this report has been asked to find and select an article with a specific purpose in mind. Namely, the author of the report is supposed to review the article for implications regarding validity and reliability. To be more precise, if there are gaps in either, the author of this report is to identify them and then identify what could be done to avoid such issues in future or different studies. A recent study about feedback interactions revealed some gaps that could be threats to reliability or validity.
To begin to evaluate the validity and reliability of the selected peer-reviewed journal, the author of this report shall first zone in on the sampling. As noted in the applicable section, the authors note "our overriding sampling logic was to find contexts that had shown a history of successfully using feedback in creative work, enabling us…

bias, internal validity, external validity, and reliability.
There are several important issues with the research conducted by this anonymous female student that impacts the reliability and validity of her findings. Firstly, it appears that the researcher formulated her hypothesis before she had gathered all the facts available regarding the topic which is a major issue. She has an opinion that lower income people vote less than those with higher incomes and seems to have looked for data to support the hypothesis rather than forming a hypothesis which accounts for the data. In addition, in the question regarding this hypothetical research it is stated that she searched the internet and library, but there is no information as to the quality or reliability of the sources that she used in her research which also calls her findings into question. I would also be concerned with the world almanac she is using as…
The critical task then is to evaluate through critical judgment how closely aligned or far removed the original goal that the secondary data was originally created to respond to. There is also the need to evaluate the credibility and biases of the authors and publishers of the secondary data. Answering this question is also critical to keep the correct context of the secondary data as well. Above all, when working with secondary data, the underlying unmet need that lead to its development in the first place, the methodologies that primary data integrated into the secondary data relied on, and any biases of the writers and publishers need to be taken into account. The bottom line is that secondary data, to have been created, was precisely aligned with an unmet information need. It is up to the researcher to ascertain how closely aligned or how far removed their specific objectives are…
It is also possible that voters could change their attitudes after having completed the questionnaire. This could affect the validity of the results for the experimental group. To handle this eventuality, several questionnaires can be delivered over time for the whole group before the experimental group is selected. A mean can then be determined to most accurately divide the group into a similar experimental and control group.
After the experimental group is determined, negative advertisements can be displayed. In order increase the validity of this experiment, a number of survey questionnaires over time can also be delivered in order to minimize non-visible influences such as an extreme reaction to a particular person in a particular advertisement. At the same time, the same number of questionnaires can be delivered to the control group.
A mean of all the questionnaires over the determined time can then provide relatively accurate data regarding whether…
Whatever the needed equipment is the company should provide the best possible so that the employees have a reduced chance of accident.
In addition, when a company provides the best possible equipment to the employees it sends them a strong message about the importance of a safety culture at work.
Modeling this way of thinking from management down to the employees will help to promote the safety culture the companies' desire.
Having a team effort to promote the safety culture of any company can only serve to boost the employee moral, save money on workman's compensation claims and reduce the number of accidents within that workplace environment.
Conclusion
For many years, employers were not to concerned with the safety factor of their employees and employees, by human nature would use risk taking behaviors to get their jobs done. This combination of human high risk behavior and lack of company care…

In some areas it actually appears as though certain reliability issues and their solutions might be simplified in the cloud when compared to traditional software and hardware set-ups; successful antivirus protection has been achieved simply by running preventative, diagnostic, and corrective programs on host computers and servers in the cloud, rather than necessitating the same type of vigilance for each and every end-user unit (Shah 2010). Solutions to more general and widespread reliability issues, however, have necessitated a much higher level of complexity in their solutions and the mechanisms employed to address them. More detailed and comprehensive infrastructure and internal architecture mapping has been adopted in an effort to better identify and rectify issues that could cause problems with reliability in cloud software systems (Mell & Grance 2009).
As understandings of these systems, their mechanisms, and their functions become more detailed and more concrete, the solutions to reliability issues will…

1. Why are reliability and validity important for assessment? How are content validity and criterion-related validity used to establish construct validity? Support your position.
Assessment instructions, whether for measuring cognitive ability or intelligence, or for psychometrics like personality, need to be both reliable and valid; otherwise, their results would be meaningless. In fact, using unreliable or invalid assessment instruments could lead to distorted judgments and biased beliefs. The decisions made based on reliable assessments can be sound and productive, whereas decisions made based on invalid or unreliable assessments may be unethical. Assessment reliability refers to how consistent the results are, and validity refers to how well the instrument measures what it intends to measure (“Reliabiity and Validity,” n.d.). The same test administered to the same population at a different point in time should yield similar results—the “test/retest” effect (Sullivan, 2011, p. 119). Likewise, assessment reliability takes into account how the…
This would be used in determining whether the prevailing employee abilities are related with their prevailing job performance based on the measurements of the criterion scores. In case of a high correlation, it concludes that there is a high validity of the concurrent criterion. This suggests that the identified abilities have measured the performance abilities on tasks that require the decision makers to measure.
For the content validity to be interpreted, a job analysis must be done, and the requirement matrix to be developed. Then interpreting the content validity would then become a judgmental procedure where organizational or external experts. These experts must be thoroughly informed and knowledgeable about the nature of the focal job tasks and job. They then deliver a judgment on whether the abilities displayed by the test results are a true reflection of the organization's identified job analysis. Assessment of content validity tests tends to be…

he availability of online information has made a tremendous difference in many fields of endeavor including daily interactions. Many journals now have articles that are 'online first' before print; others comment on these online articles and critique even before the print issue exists. Online access also broadens the ease of accessing materials without a nearby extensive library. his is true in nearly every profession: science, economics, finance, business, nursing, medicine, hairdressing, and etc., (Leiner et al., 2003). Access to online information has changed the information paradigm. here is now a necessity and obligation to understand what appropriate online information consists of.

eliability and Validity
eliability
eliability refers to the capacity of an instrument to capture the most accurate and "truest" score of an individual. A reliable test enables us to distinguish one individual from another with confidence that errors will primarily be generated by individual differences, and to a lesser extent, to the imperfections of the instrument. Indicators that a test is reliable include test-retest reliability that is accounted for by the internal consistency in the components of the test. The test-retest criteria is generally considered a manifestation of the consistency of measurement for individual performance over time, such that the score a person gets on a test today will be the same -- or nearly the same -- as the score the person gets on a test, say, in three, six, or twelve months. There are a number of substantive issues with the test-retest criteria, including chance covariation, memory, and…

eliability and Validity in esearch
eliability
eliability is a term used to talk about the "test-retest" quality of a measurement. eliability refers the capacity of a measurement to obtain the same results over many repetitions when all the underlying conditions are stable (Chisnall, 2005; Saunders, Lewis and Thornhill, 2009). Many research variables can change over time, and these variables can impact reliability. However, statistical procedures exist to correct for most of those changes and to allow reliable data to be collected.
eliability of the questionnaires
Of the three options for establishing reliability (equivalent forms, internal consistency, parallel forms, and test-retest), internal consistency offers the most practical application for a survey to be used for concept testing or a product launch (Mitchell, 1996). To implement a strategy for determining internal consistency, a market researcher designs a number of survey questionnaire items that measure the same construct (idea, phenomenon, thing) (Chisnall, 2005).…

An abbreviated four-subtest version of the WAIS-III (called the Wechsler Abbreviated Scale of Intelligence (WASI)) has been released enabling clinicians to perform a validated verbal, performance and full-scale IQ in approximately 30 minutes.
Some clinicians use the WAIS with psychiatric illness or brain injury in order to assess impediments in cognitive reasoning, but use of the WAIS in this connection is controversial. The WAIS is also used as an instrument on a neurologically impaired population in order to link regions of the brain to specific variables of reasoning, as well as to gauge regions and extent of affected neural matter (the digit span, for instance, may be used to test attention and/or memory). Oftentimes, however, the WAIS- NI (Wechsler Adult Intelligence Scale-evised) is a preferred neuropsychological instrument. The WAIS was developed for average, brain-healthy individuals, and separate norms, patterned on…

Definition and Description of Basic Concepts Error of measurement Measuring devices make approximate measurement(s). If an object is measured twice at different times, the two obtained measurements may not be accurate. This difference between the measurements is called error of measurement. This error, however, is not considered a mistake or the incorrect measurement. In fact, the error in measurement is a numerical method for showing that measurements are not certain. In simple words, error of measurement is the variation between the measurement result and the correct value of the object that is being measured. According to recent studies, "the measurement error affects the repeatability of MMN" (Paukkunen, Leminen & Sepponen, 2011, p. 2195) (mismatch negativity). Test-retest eliability Test-retest reliability is the estimate between scores from the similar respondents tested at dissimilar times (MacQuarrie, Applegate & Lacefield, 2008).

Psychological Testing
Psychological tests are an important aspect of clinical psychology. Psychological tests are normally administered by professional psychologists as a way of learning fact on how people function or in predicting their future. The paper will look at the definition of the term test, give a description of the major categories of tests while identifying the major uses and users of these tests. There will also be comparing and contrasting the concepts of validity and reliability and a discussion of how they affect the psychological testing field.
Definition of tests
A test or examination is defined as an assessment aimed at measuring the knowledge, aptitude, skill, physical fitness or classification in other different topics. Tests can be administered orally, by use of a paper, computer or in the confinement of a specific area which requires the person taking the test to physically perform a specific set of skills. Tests…

group and the nature of the study population. Both may present limitations to the researcher that will be reflective in the study design. In a quasi-experimental study, for instance, the study design lacks a fundamental component of a customary experimental design, namely randomization of the participants into study groups. Geographic limitations or the specificity of the participation qualifications may hinder the researcher from randomizing the subjects. An ex post facto study investigates possible cause-and-effect relationships by observing an existing condition and looking back into the past for valid causal factors. A certain study bias, however, is inherent in this type of study design because the variables are separated by time. Meanwhile, a correlational study compares two or more variables concurrently in detailed bivariate regression analyses. A common objective of this type of study is to determine the correlation between certain defining characteristics of the subjects and the effectiveness of some…

Wal Mart Stats
Wal-Mart Survey Analysis
In order to begin addressing two key research questions, how can Wal-Mart ensure decent quality products and simultaneously keep consumers happy with prices and how would Wal-Mart keep the costs of its products down, a survey of Wal-Mart customers was taken. Attitudes towards prices, quality of products, and overall shopping experiences were collected and analyzed via in-person questionnaires/surveys to consumers exiting Wal-Mart stores after shopping. All responses were recorded on a Likert scale of 1-5, with 5 representing high satisfaction or strong agreement and 1 representing extreme dissatisfaction or strong disagreement. The following paragraphs assess the quality of this survey and its results in terms of addressing the research question.

oyal Dutch Shell PLC and Its Edge on the Global Market
The concept of financial analysis is a core indicator of the actual financial health of a given organization. The development of an accurate and dependable conceptual framework to be employed in the analysis of the global and corporate financial system has for quite a long time been an important issue in corporate accounting (Bodie & Merton,1990). An appropriate conceptual framework must be able to meet two main objectives: to effectively address the differences that exists in the institutional structures as well as to explain the main changes in the institutional structures over time. A review of extant literature has been dedicated to the concept of financial analysis. Most of these studies have dwelt on financial ratios. A study by Nenide, Pricer & Camp (2008) indicated that extant literature in accounting as well as finance indicate that the application of…

The moment of truth was when the front desk people realized that the problem we reported was not just a minor complaint or just an example of customers being too picky or demanding. It was fairly clear that the hotel personnel immediately empathized with our situation and that they felt obligated to rectify the problem for us. The wrong response would have been to tell us that we should just try to live with the noise for one night until another room like the one we booked became available or to turn off the air conditioner when we wanted to go to sleep and then turn it back on in the morning. In addition to being insulting (because nobody needs to be told that they can do either of those two things), that type of response would have conflicted with any demonstration of reliability, assurance, or responsiveness.

In the future, this could result in some kind of major restructuring to deal with these issues. The problem is that these changes will occur when the company is facing greater challenges. This will hurt their competitive position, profit margins, stock performance and brand image. The above information will impact an investor's decision, by making them more cautious about purchasing the company over the long-term. ("The Coca Cola Company," 2012) ("Pepsi Co," 2012)

Complaints From Community Members
The fact that Officer Daniels has received complaints filed by multiple different members of the community in a relatively short period of time would raise immediate concerns. Whereas an isolated complaint could be the result of a misunderstanding, an unfounded act of retribution by someone for appropriate police action initiated by the officer, or the result of a single bad momentary decision, the fact that there are multiple such complaints suggests it is more likely that Officer Daniels may not be performing his duties optimally. Moreover, the fact that the complaints involve three different types of unrelated conduct suggests that there might be a common underlying issue such as psychological fatigue, burnout, or unresolved psychological trauma, as opposed to a an issue of poor or insufficient training (Miller, 2007). As a police psychologist, I would approach the situation as a possible unconscious request for help by…

OGC divides GIS products or software into two categories, compliant and implementing products, based on their level of compatibility with OGC specifications, which aid them in communication. In recent times, an explosion of online mapping applications has given the public enormous geographic information. The…

The Gold Coast area has a reputation as a flood prone area, even without considering the effects of global climate change.
The Gold Coast area comprises seven major catchment areas including the Tallebudgera, Currumbin, Nerang iver, Coomera iver, Pimpama iver, South Moreton Bay, Sandy Creek and Broadwater area (Mirfenderesk, 2009). The Nerang iver catchment is adjacent to the Tallebudgers catchment to the South. It is bordered by the Broadwater and Coomera iver area to the North. The Nerang iver catchment is adjacent to the Pacific beach area as well (Mirfenderesk, 2009).
Catchment areas have different levels of tolerance before the concentration of water to sediment reaches saturation levels, creating the likelihood of flooding in the area. The Tallbudgers, Currubin, and Broadwater area have time concentrations of approximately 3 hours, creating conditions favorable to short duration local flooding (Mirfenderesk, 2009). The Nerang iver and Coomera catchments have time of concentrations from…

As emotionally intelligent employees are reportedly more content, conscientious and committed in the workplace, businesses and organizations are repeatedly advised to recruit and retain these individuals. Abraham (2006), nevertheless, reports that the strongest findings emerging from her study was.".. The effect of job control on emotional intelligence." She contends that emotionally intelligent employees will not just naturally thrive in their workplace; that the work environment needs to provide independence in decision making for employees to succeed.

tests (CTs) and scales vs. norm-eferenced
Criterion-referenced tests (CTs) are often the preferred method of assessing the performance of many practitioners in the healthcare and 'helping' professions such as nursing. An example of a criterion-based objective is that a student mastered 90% of the terms on a particular test (McDonald 2002). The NCLEX (National Council Licensure Examination) for nurses is an example of such a test: all nurses that pass the test can obtain licensure. The test is deemed to be both reliable and valid. "The reliability of the NCLEX examination is assessed via a decision consistency statistic. This statistic is used instead of a traditional reliability statistic such as Cronbach's alpha because it captures the reliability of dichotomous pass/fail decisions rather than the reliability of continuous scores or ability estimates" (eliability of NCLEX, 2013, NCSBN: 2).
In terms of the NCLE, the exam attempts to ensure content validity; face…

Second, the researcher's intense exposure to study of a case can bias the findings (the case study as a research method); at the least, there are significant opportunities for subjectivity in the implementation, presentation, and evaluation of case study research (Case studies). This high degree of subjectivity opens the door for ethical issues, particularly if the study is being sponsored by a special interest. Third, case studies involve too much investment of time and money to be appropriate for large-scale research projects (Case studies).
eyea and Nicoll (1997) discuss the many factors that researchers need to consider when selecting a sample for a research project. A researcher must first determine the population of interest (every person, event, or object that meets specific characteristics). If the population of interest has too many members to study, the researcher then needs to formulate a sampling strategy to obtain a subset of the population…

Beck Depression Inventory-II (BDI-II) is a 21-item clinician administered and scored scale that is designed to measure a person's mood and symptoms related to depression. The BDI-II was designed to conform to the DSM-IV depression diagnostic criteria and represents a substantial improvement over its predecessor, the original Beck Depression Inventory. The BDI-II has been used both as a research measure (its primary intended use) and to assist with the clinical diagnosis of depression. The BDI-II has been subject to numerous empirical studies designed to measure its internal consistency, convergent and discriminant validity, criterion validity, and construct validity and the test demonstrates acceptable psychometric qualities, but there have been some concerns with its use. This paper reviews the development of the BDI-II, its psychometric properties, uses, strengths, and weaknesses. Advantages and disadvantages of using the BDI-II and recommendations for future research regarding its use are also discussed.

Similarly, researchers should be aware of the consequences of halo, prejudice to the leniency or seriousness of fundamental trend and position or propinquity of deviation from the pace that can artificially increase reliability of measure devoid of improving reaction correctness or validity. (Williams, and Poijula, 2002).
Limitations/Strength and Weaknesses
The following conditions might have affected the results of the present study:
1. The sample will not be random,
2. all demographic information will be self reported and not verified,
3. all the subjects for the study came from 3 local Kansas mental health facilities located in South Central Kansas,
4. all data for the BDI-II is self reported,
5. data is for individuals with specific DSM-IV diagnosis,
6. data is for individuals who are currently seeking treatment for the specified DSM-IV disorders (Schiraldi, 2000)
major strength is that respondents will be selected from ? number of different places for better…

Test Development
This research is a mixed methods study designed to explore the perceptions of self-identifying individuals with anxiety and depression regarding any relation between their conditions and their ability to access appropriate healthcare under the Patient Protection and Affordable Care Act. Five respondents completed the questionnaire constructed explicitly for this research study. A review of the literature serves as a canvas of instruments also developed for assessing Axis 1 disorders as defined by the Diagnostic and Statistical Manual (DSM-5). The research on instrumentation included the following: 1) The SCID, 2) the Composite International Diagnostic Interview (CIDI), 3) the Beck Depression Inventory (BDI), 4) the Center for Epidemiologic Studies of Depression Scale (CES-D), and 5) Severity Measure for Generalized Anxiety Disorder -- Adult (an emerging online measure provided in association with the DSM-5).
Their responses negate the theoretical construct, however, an insufficient number of respondents in this pilot study meant…

Scale to Measure Celebrity Endorsers
In this study by Ohanian, a scale used in measuring celebrity endorsers' expertise, trustworthiness as well as attractiveness is developed. Psychometric scale development protocols are followed for testing the data reliability and validity as well. In addition, this study uses two exploratory and confirmatory samples to initiate a 15-item scale measuring the celebrity endorsers' characteristics. This article complies fully with Churchill's recommendations in several fronts as outlined below.
Several sources are researched on to identify words, phrases, and adjectives to use for this research's questionnaire; this results in the development of several adjectives describing personality traits. During the construction of the scale, 182 adjectives are identified of which some were eliminated to about 139 adjectives. Additionally, the 139 descriptors were further trimmed by a group of 38 college students; the researcher believed the words were unfamiliar with respondents, to 104.
