Improved Margin Of Error Estimates For Proportions In Business: An Educational Example
Get PDFThis paper presents the Agresti & Coull “Adjusted Wald” method for computing confidence intervals and margins of error for common proportion estimates. The presented method is easily implementable by business students and practitioners and provides more accurate estimates of proportions particularly in extreme samples and small sample situations. The proposed method may have particular applications to focus group analysis, industry benchmarking, and destructive testing sampling. The paper discusses a computational strategy and several comparison examples
Social Networks In The Classroom: Personality Factors As Antecedents Of Student Social Capital
Get PDFThis study examines personality factors as antecedents of student social capital. We hypothesize relationships between two constructs taken from the five-factor model of personality (agreeableness and extraversion) and two variables that reflect a student’s social capital (quantity of ties and strength of ties) in an academic setting. Analysis of roster-based, sociometric data suggests that agreeableness is associated with higher quantity of ties, but not higher tie strength. In contrast, extraversion is linked to higher tie strength, but not higher overall network size. The paper concludes with a discussion of the implications of student social capital for educational research and practice
From Dan To Danita: LGBT Based Discrimination And Issues Of Religious Freedom
Get PDFIn this two-part case study, Dan Flint faced a dilemma that was not of his own making. He saw himself as a “…female imprisoned in a male’s body.” In attempting to get a “grip” on his gender identity, he consults a renowned sex therapist and a barrage of emotions and feelings that make up his inner core nature are revealed. He faces the reality that “coming-out” is fraught with many issues and dilemmas. Will his transgendered state be understood? Will he undergo surgical procedures which will give him female anatomical parts? How will he face his work environment, supervisors, and co-workers? And finally, will he be accepted as a person with value and dignity? The case shows the difficulties that Dan faced in transitioning to Danita in a workforce that reacted with confusion, uncertainty and skepticism. The case presents in the first part, seven questions that bring up the interpersonal, ethical and managerial questions imbedded in the case study, and explore how a supervisor might prepare the organization for dramatic change. In the second part, President Obama’s Executive Order on prohibition of discrimination on LGBT workers, coupled with Employment Non-Discrimination Employment Act (ENDA), and the Supreme Court decision on religious freedom (Hobby Lobby) are woven into a series of important issues, concluding with a debate scenario
Self-Determinations Intrinsic Value For Post-Exile Cuban-American Women
Get PDFThis study provides insight into the role of self-determination for post Castro Cuban-American women in leadership roles in the United States. It provides a description of the dynamics and social influences that shaped, guided, and supported their self-determination skills. It outlines the process they used to achieve personal control over their lives and what empowered them to accomplish the things they perceived as important. The findings reveal the role and effect that self-determination had in how this particular group of women became leaders and how their self-determination stems from their passion, determination, and sense of responsibility to care and support others
Developing Critical Thinking Skills: Assessing The Effectiveness Of Workbook Exercises
Get PDFTo address the challenge of developing critical thinking skills in college students, this empirical study examines the effectiveness of cognitive exercises in developing those skills. The study uses Critical Thinking: Building the Basics by Walter, Knudsvig, and Smith (2003). This workbook is specifically designed to exercise and develop critical thinking skills. The authors use it as the intervention tool. Freshman students enrolled in a first-year experience course participated in the study; one group used the book, the other did not. Students spent a few weeks in class working through the problems, and at the end of the semester, both groups completed the iCritical Thinking Skills Test. Analysis of final test scores prove the effectiveness of exercises on improving the critical thinking skills of college freshmen.
International Diversification, Corporate Social Responsibility, And Corporate Governance: Evidence From Korea
Get PDFWe examine how multinational corporations’ (MNC) international diversification (ID) is related to their corporate social responsibility (CSR) activities in the domestic market. We also investigate whether corporate governance, specifically the conglomerate (chaebol) structure, affects the relationship between ID and CSR activities in the domestic market. We perform empirical analysis using a sample of 606 firm-year observations of Korean-listed manufacturing MNCs from 2005 to 2010. We find that ID is negatively associated with CSR, and that this relationship is stronger for chaebol firms. These results are robust after controlling for various factors that affect measurements of ID. Our findings suggest that ID related to market diversification through exports and foreign affiliates appears to push MNCs to perform fewer CSR activities in the domestic market. Our findings also indicate that the effect of chaebol firms on the relationship between ID and CSR is greater than that of non-chaebol firms in Korean market. Our study contributes to the ID and CSR literature as the first study to provide empirical evidence on the association between ID and CSR activities in the domestic market for Korean firms using three aspects of ID measurement. Given that empirical evidence on this issue is very limited, our findings have implications for academics, practitioners, and policymakers in understanding the relationship between ID and CSR strategy
Organizational Agility
Get PDFThe current competitive environment is characterized by high-intensity rivalry in a dynamic and uncertain environment. The ability to respond swiftly and effectively to these changes is a necessity that separates successful organizations from those that flounder. This paper reviews the concept of organizational agility by exploring the current understanding of the concept, relevant literature and a conceptual framework. Potential avenues for further research are explored
The Impact Of Financial Crisis On Islamic And Conventional Indices Of The GCC Countries
Get PDFWe study performance of Islamic and conventional indices of the Gulf Cooperation Council (GCC) countries in the wake of financial crisis of 2008 and test whether Islamic indices were less risky than conventional indices. We make use of data of the six GCC markets as well as the Dow Jones Islamic Market Index GCC. The mean and variance of each of the indices are analyzed based on augmented GARCH models. The results show that the financial crisis impacted on the mean returns of Bahrain, the other indices remained unaffected. The financial crisis, however, impacted volatility in three GCC markets (Kuwait, Bahrain, and the UAE), while the impact on the remaining markets (Saudi Arabia, Oman, and Qatar) and the Islamic index was insignificant. More interestingly, we show that the Islamic index did not exhibit lower volatility than its conventional counterparts
Can Derivative Information Predict Stock Price Jumps?
Get PDFThis study examines the predictability of jumps in stock prices using options-trading information, the futures basis spread, the cross-sectional standard deviation of returns on components in the stock index, and exchange rates. A stock price jump was defined as a large fluctuation in the stock price that deviated from the distribution thresholds of the past rates of return. This empirical analysis shows that the implied volatility spread between ATM call and put options was a significant predictor for both upward and downward jumps, whereas the volatility skew was less significant. In addition, the futures basis spread was moderately significant for downward stock price jumps. Both the cross-sectional standard deviation of the rates of return on component stocks in the KOSPI 200 and the won-dollar exchange rates were significant predictors for both upward and downward jumps
Web 3.0: Governance, Risks and Safeguards
Get PDFMany organisations consider technology as a significant asset to generate income and control cost. The Web is recognised as the fastest growing publication medium of all time. This mass of unstructured information presents many new opportunities for organisations. The Web acts as an enabler for technological advancement, and has matured in its own unique way. From the static informative characteristics of Web 1.0, it progressed into the interactive experience Web 2.0 provides. The next phase of Web evolution, Web 3.0, is already in progress. Web 3.0 entails an integrated Web experience where the machine will be able to understand and catalogue data in a manner similar to humans. This will facilitate a world wide data warehouse where any format of data can be shared and understood by any device over any network. Organisations need to be ready, and acquire knowledge about the opportunities and risks arising from Web 3.0 technologies. The objective of this study is to investigate the risks an organisation will be exposed to when interacting with Web 3.0 technologies. The study proposes to provide insight into the risks arising from the use of Web 3.0, and to recommend possible safeguards to mitigate these risks to an acceptable level
