...research designs according to which one can conduct his/her research. These research designs are: 1. Experimental design 2. Longitudinal design 3. Explanatory design 4. Cross sectional design 5. Case study design DESIGN THAT SUITS OUR TOPIC: Keeping in consideration all other methods and designs, we think that cross sectional design suits our research topic. Cross sectional design may be defined as “A basic type of research method in which a large cross-section of the population is studied at one specific time and the differences between individual groups within the population compared.” The most important advantage of cross sectional studies is that in general they are quick and cheap. As there is no follow up, fewer resources are required to run the study. Cross sectional studies are the best way to determine prevalence and are useful at identifying associations that can then be more rigorously studied using a cohort study or randomized controlled study. Cross-sectional surveys can be conducted using any mode of data collection, including telephone interviews in which landline telephones are called, telephone interviews in which cell phones are called, face-to-face interviews, mailed questionnaires. Cross-sectional studies are observational in nature and are known as descriptive research, not causal or relational. Researchers record the information that is present in a population, but they do not manipulate variables. This type of research can be used to...

The idea of a railway to connect Bombay with Thane, Kalyan and with the Thal and Bhore Ghats inclines first occurred to Mr. George Clark, the Chief Engineer of the Bombay Government, during a visit to Bhandup in 1843. The formal inauguration ceremony was performed on 16th April 1853, when 14 railway carriages carrying about 400 guests left Bori Bunder at 3.30 pm "amidst the loud applause of a vast multitude and to the salute of 21 guns." The first passenger train steamed out of Howrah station destined for Hooghly, a distance of 24 miles, on 15th August, 1854. INDIAN RAILWAYS, the premier transport organisation of the country is the largest rail network in Asia and the world’s second largest under one management.Indian Railways is a multi-gauge, multi-traction system covering the following: |Track Kilometres |Broad Gauge |Metre Gauge |Narrow Gauge (762/610 mm) |Total | | ...

...GENERAL CONCEPT MULTIPLE CHOICE QUESTIONS 1. General Mills conducted research on a "new, improved" version of their cereal, TRIX. Consumer taste tests showed the new version was preferred over the old TRIX, but the new version was a failure when it was introduced. It was noted that the research was flawed in that the new version of TRIX was compared with the old TRIX, a choice that consumers in the marketplace would not have. The correct research should have compared the new TRIX with competitor brands. This example was presented in your text to illustrate: a. poor budgeting for research b. how researchers in large firms are in "silos" and are not open to outside suggestions c. how former research studies often determine the design of present studies d. improper research design e. a case where exploratory research should have been undertaken after the causal research Answer: (d) Difficulty: (Moderate) Page: 114 2. Which of the following is true about research design? a. Research design should be the first consideration in a research project. b. Research design decisions should be made after data analysis. c.

...when selecting a research design? AUTHOR’S NOTES: CHAPTER FOCUS This chapter provides an overview of research design. A definition and a classification of research designs are presented. The differences between exploratory and conclusive research designs are discussed. The three basic types of research designs, namely exploratory, descriptive, and causal, are described and a comparative analysis of these designs is presented. The potential sources of errors in research designs are covered in some detail. The budgeting and scheduling of a marketing research project, as well as the preparation of a marketing research proposal, are covered. This chapter is similar to competing texts with regard to the material on the basic types of research designs. It is different in that it presents a comparative analysis of these designs and also gives a unified treatment of errors associated with research designs. This chapter could be taught by focusing on the opening questions sequentially. Greater emphasis could be placed on the differences between exploratory and conclusive research (Opening Question 2) and on the material on exploratory, descriptive, and causal research (Opening Question 3). The potential sources of errors in a research design should be...

...Journal of Ltd 2007performance XXX UK Publishing Management Reviews © Blackwell 1460-8545 International and organizational IJMR Oxford, Blackwell ARTICLES Anne Delarue,1 Geert Van Hootegem, Stephen Procter and Mark Burridge This paper presents a review of recent survey-based research looking at the contribution of teamwork to organizational performance. In particular, it focuses on empirical studies in which both teamwork and performance are directly measured in a quantitative way. The paper begins by identifying four interrelated dimensions of teamwork effectiveness: attitudinal, behavioural, operational and financial. The first two represent transmission mechanisms by which organizational performance can be improved. The latter two provide direct measures of organizational outcomes. The review shows that teamworking has a positive impact on all four dimensions of performance. It also reveals that, when teamwork is combined with structural change, performance can be further enhanced. The paper concludes by highlighting some important research gaps that future studies could address. Introduction Teamwork has emerged in recent years as one of the most important ways in which work is being reorganized (Osterman 1994; Waterson et al. 1997). This idea of delegating responsibilities to work groups has been diffused under a range of different labels. Human resource management (HRM), modern sociotechnical theory, business process re-engineering and lean production...

...continue peak performance when they reach their thirties or forties indicates that deterioration begins at a relatively young age and progresses in severity from that point on. Indeed, many studies have confirmed that most physiological processes deteriorate progressively after about thirty years of age, some functions more severely affected than others. Most of the research on age-associated physiological deterioration has utilized cross-sectional studies; that is, subjects of different ages are studied at a given point in time (e.g., the calendar year 1990). These are called cross-sectional studies because the data are collected from a cross section of the population. Since this study design provides information quickly and relatively inexpensively, it is widely used. However, because of generational factors and selective mortality, the cross-sectional design can yield erroneous information about aging. An example of how a generational factor may confound an aging study is illustrated by a hypothetical 1970 cross-sectional study of cognitive function in which Americans in the third decade of life were compared with those in the tenth decade. It is critical to note that the average number of years of schooling of Americans has increased markedly during the twentieth century. Therefore, if this study finds cognitive ability of those in the tenth decade of life to be less than in those in the third decade, it may be due to the difference in educational level or to age-associated deterioration...

...Critical review of: An employment systems approach to turnover: Human resources practices, quits, dismissals, and performance. By Rosemary Batt and Alexander J.S Colvin (August, 2011). Academy of Management Journal, 54 (4): 695-717. Introduction Drawing on internal labor market and efficiency wage theories, this study intends to contribute in turnover and employment systems literature by examining theoretically and empirically whether applying three categories of human resources (HR) practices, instead of treating HR practices as a consistent group (Batt and Colvin, 2011: 697), might produce similar effects on quits and dismissals rates. Previous researches had diversified views about the causes of quit and dismissals due to various factors and conditions that were considered in these studies and theoretically show plausible dissimilarity. In addition, the authors attempt to explore the potential effects of those sets of HR practices and turnover on the organizational performance and the reflections on customer satisfaction. Hypotheses Batt and Colvin (2011: 696-701) analysis and arguments about the current literature yield seven hypotheses. Whereas employers in which apply two sets of incentive HR practices, namely, high-involvement work and attractive investments and inducements practices, they may encounter lower turnover rate and higher level of operational performance. By contrast, the third set of these incentive HR practices, labeled performance-enhancing...

...doing so; the study of different groups of people of different ages, called a cross-sectional design, the study of the same people over a period of time, called a longitudinal design, and the combining of cross-sectional and longitudinal designs in some fashion in a sequential design. What are the strengths and limitations of each of these designs? Other research methods are; systematic observation, self-reports, the clinical method, and ethnography. What are the similarities and differences of these methods? Let us now examine these fascinating topics. Cross-Sectional, Longitudinal, & Sequential Designs Cross-sectional design studies groups of subjects that are selected at each of a series of ages. The results may seem to indicate that there are major changes based on age. However, cross-sectional data about adults can differ not only in age, but in cohort. Influences of this kind lead to cohort effects, findings that are the result of historical factors to which one age group in a cross-sectional study has been exposed. Cross-sectional studies cannot tell us anything about sequences of change over age, or about the consistency of individual behavior over time, because each subject is tested only once. Cross-sectional research is useful because it is relatively quick to do and can give us a glimpse of possible age differences or age changes. (Berk, 2010) Longitudinal designs seem to solve the problems of cross-sectional research because...

Cole Vanderbilt University Scott E. Maxwell University of Notre Dame R. M. Baron and D. A. Kenny (1986) provided clarion conceptual and methodological guidelines for testing mediational models with cross-sectional data. Graduating from cross-sectional to longitudinal designs enables researchers to make more rigorous inferences about the causal relations implied by such models. In this transition, misconceptions and erroneous assumptions are the norm. First, we describe some of the questions that arise (and misconceptions that sometimes emerge) in longitudinal tests of mediational models. We also provide a collection of tips for structural equation modeling (SEM) of mediational processes. Finally, we suggest a series of 5 steps when using SEM to test mediational processes in longitudinal designs: testing the measurement model, testing for added components, testing for omitted paths, testing the stationarity assumption, and estimating the mediational effects. Tests of mediational models have been an integral component of research in the behavioral sciences for decades. Perhaps the prototypical example of mediation was Woodsworth’s (1928) S-O-R model, which suggested...

...Q) Evaluate the use of a longitudinal research design when considering upbringing as an explanation for criminal behaviour. (15) A) Longitudinal studies are psychological investigations carried out over a long period of time, or at various intervals over a long period of time. They allow psychologists to study changes in behaviour and, for instance, partiality to crime, and how this behaviour and the attitudes of those partaking in such behaviour change over time and why. But there is a flaw in the fact that longitudinal studies like Farrington, et al., have many extraneous variables that can affect the validity of the results. This is not an issue for studies like Wikstrom & Tafels Peterborough Youth Study, which was a snapshot study â a study conducted at just one point in time â and consists of a singular analysis of the school reports of 2,000 14/15 year olds and one interview, thus making the practicality of psychological research far easier than the 40 year-long longitudinal study Farrington conducted. On top of this, the most commonly used approach to collecting data from longitudinal research is self-report; both Farrington and Wikstrom & Tafel used them. Self-report techniques are a good indicator of partiality to criminal behaviour because you can ask personal questions and learn about smaller crimes that unreliable criminal records (used by Farrington in a bid for concurrent validity) and school reports (used by Wikstrom and Tafel for the same purpose) omit...

...Chapter 1 – Study Questions: 1. What are the four key features of the lifespan perspective as identified by Paul Baltes. Provide original examples for each feature. (pp. 4-5) Paul Baltes identified 4 features of the life-span perspective: 1. Multidirectionality: development involves both growth and decline – as people grow in one area they may lose in another and this may occur at different rates Ex: (Book): people’s vocabulary abilities tends to increase throughout life, but reaction time tends to slow down. Ex: (original): Language acquisition. At a young age children are able to learn multiple languages very quickly. However, as they get older, their ability to learn multiple languages quickly becomes more difficult. Social situations. At a young age children are not able to understand complex social situations such as parents fighting or divorce or financial problems between their parents. As they grow up and age, they begin to understand these social situations and deal with them. They may comfort a parent through a hard time, or go get a job to help with the financial situation. 2. Plasticity: One’s capacity is not predetermined or set in concrete. Many skills can be trained or improved with practice, even late in life. There are limits to the degree of potential improvement Ex: (original): Your IQ is not predetermined. You’re ability to play a sport is not predetermined. With practice and dedication you can improve your ability to play the sport. However...

Define cohort and briefly summarize at least one major difference in how different cohorts, past and present, are experiencing childhood, old age, and adulthood (pp. 5-9). Cohorts are the birth group we grow up with through life. The past childhood cohort was growing up in a time when there wasn’t terrorism, internet, and when a child would quit school to help his fathers business. Nowadays, children are exposed to the media, social cliques and must stay in school for the duration of there childhood years. 2. Summarize the impact of socio-economic status, culture and ethnicity, and gender on development (pp.9-12). In the developing world, people are struggling for survival and their living standards are very bad, while in the developed world, things are the opposite. Culture and ethnicity place a huge tax on the development of man or woman. There are many different types of culture and ethnicity based on our parents’ background in most cases. In a Collectivist culture, one might be accustomed to hiding his feelings and always allowing the...
