Evaluating Key Factors In Supplier Selection For Micro-Businesses: Implications For Buyer Satisfaction, Avinash M. Waikar, Minh Q. Huynh, Robert F. Cope, Uday S. Tate

Management Faculty Research

Final quality of products/services starts with suppliers in the supply chain. Problems can occur if suppliers do not deliver the quantities requested in full, on time, or buyers select suppliers solely on the basis of lowest price. Supplier selection has been studied for large businesses but not for very small (micro) businesses. Therefore, a survey was administered to micro-businesses to determine: what factors are important to micro-businesses in selecting suppliers and how satisfied they are with their suppliers. Factors included Brand Name, Consistency, Cost/Lower Price, Loyalty, Quality, and Warranty. Results indicated that none of the factors were unimportant. However, buyer …

Optimal Service-Based Competition With Heterogeneous Suppliers, Ehsan Elahi, Saif Benjaafar, Karen L. Donohue

Management Science and Information Systems Faculty Publication Series

We investigate how a competition can be designed to maximize expected profit for a buyer who wishes to allocate demand among a diverse set of suppliers when his profit is dependent on the supplier’s service levels. The candidate suppliers are heterogeneous in their capacities and cost structures, and compete for shares of the buyer’s demand based on their promised service levels. To characterize the optimal competition, we first identify a family of allocation functions that are service maximizing, meaning they can intensify the competition to a point where each supplier provides its maximum feasible service level and the outcome of …

Effects Of Cultural Ethnicity, Firm Size, And Firm Age On Senior Executives' Trust In Their Overseas Business Partners: Evidence From China, Crystal X. Jiang, Roy Yj Chua, Masaaki Kotabe, Janet Y. Murray

Management Department Faculty Journal Articles

We investigate trust relationships between senior business executives and their overseas partners. Drawing on the similarity-attraction paradigm, social categorization theory, and the distinction between cognition- and affect-based trust, we argue that executives trust their overseas partners differently, depending on the partners' cultural ethnicity. In a field survey of 108 Chinese senior executives, we found that these executives have higher affect-based trust in overseas partners of the same cultural ethnicity as themselves; cognition-based trust is associated with affect-based trust differently when overseas partners are of the same or different cultural ethnicity. We also examine the role of relative firm size and …

Transformational Leadership For Conflict Management Between Leaders And Employees, Yang Guo

Lingnan Theses

This study empirically investigates the dynamics and outcomes of leader-member conflict. It validates the values of cooperative conflict and damages of competitive conflict between leaders and employees, testing the effectiveness and universality of Deutsch's (1973) cooperation and competition theory. By bridging leadership and conflict management literature, it also identifies the role of transformational leadership in managing conflict effectively. Specifically, transformational leadership induces cooperative conflict and undermines competitive conflict between leaders and employees, which in turn increases task performance and leader effectiveness.

A total of 112 interviews were conducted in mainland China from 2010 to 2011. Results of structural equation modeling …

Examining The Knowledge Sharing And Uncivil Behavior Of Envious Employees: An Affective Events Theory Perspective, Ankur P. Nandedkar

Theses and Dissertations - UTB/UTPA

Envy is deep-rooted within human nature and considered as a socially undesirable emotion. According to social science scholars, competitive situations are breeding grounds for various feelings of ill-will. Researchers have demonstrated that an organization's systems and structure permit envy to exist and thrive even in the workplace. Within a workplace setting, various job-related scenarios such as positions held, promotions, projects assigned, job design, pay increases, and performance recognition can lead to envious feelings, which in turn, can have negative consequences. There are some organizations in which employees engage in close interactions on a regular basis and share a high degree …

Social Capital: Measurement, Dimensional Interactions, And Performance Implications, James Turner

All Dissertations

ABSTRACT
Recent OM literature conceptualizes social capital as being comprised of three inter-related dimensions: the relational dimension, the structural dimension, and the cognitive dimension. Existing research suggests that ocial capital offers firms the potential to leverage their interorganizational relationships to create sustainable advantage and superior performance opportunities for the firm.
However, despite the interest and attention of social capital theory among operations management (OM) and supply chain management (SCM) researchers, there is a surprising shortage of cohesive empirical research on social capital theory. The absence of reliable and valid empirical measures of social capital has limited OM researchers' ability to …

The Role Of Age In Technology-Induced Workplace Stress, Stefan Tams

All Dissertations

Recent research shows that such Information and Communication Technologies (ICTs) as instant messengers can cause workplace interruptions, which lead to stress for employees and substantial productivity losses for U.S. organizations. Since the introduction of ICTs, workplace interruptions have evolved in both frequency and nature from irregular phone calls to a continuous stream of e-mail notifications and other electronic interruptions, mediated through a large number of technological devices that constantly beep and buzz. This trend of an increasing frequency of workplace interruptions closely relates to another workplace trend: the graying of the workforce, implying that the U.S. workforce is aging at …

Understanding The Role Of Embeddedness In Shaping It Professional Behavior, Michael Dinger

All Dissertations

This dissertation studies how information technology (IT) professionals become embedded and, in turn, how embeddedness influences organizational behaviors. Embeddedness refers to the extent to which an individual is attached to an organizational or professional setting. Traditionally, embeddedness is defined as having three components: social links, fit and sacrifice. We analyze the traditional conceptualization of embeddedness and identify weaknesses. As a result, we refine these three components to belongingness, fit and utility.
To deepen our understanding of embeddedness and its influence on organizational behavior, we develop a theory of embeddedness. We propose that embeddedness grows over time. As embeddedness increases, we …

Psychological Capital And Employee Performance: A Latent Growth Modeling Approach, Suzanne J. Peterson, Fred Luthans, Bruce J. Avolio, Fred Walumbwa, Zhen Zhang

Department of Management: Faculty Publications

The positive core construct of psychological capital (consisting of efficacy, hope, optimism, and resilience) has been conceptually and empirically demonstrated to be related to employee performance. However, much of this work has relied on cross-sectional designs to examine these relationships. This study utilizes longitudinal data from a large financial service organization (N = 179 financial advisory-type employees) to examine withinindividual change in psychological capital over time and if this change relates to their change in performance. Latent growth modeling analyses revealed statistically significant within-individual change in psychological capital over time, and that this change in psychological capital was related to …

Meta-Analysis Of The Impact Of Positive Psychological Capital On Employee Attitudes, Behaviors, And Performance, James B. Avey, Rebecca J. Reichard, Fred Luthans, Ketan H. Mhatre

Department of Management: Faculty Publications

The positive core construct of psychological capital (or simply PsyCap), consisting of the psychological resources of hope, efficacy, resilience, and optimism, has recently been demonstrated to be open to human resource development (HRD) and performance management. The research stream on PsyCap has now grown to the point that a quantitative summary analysis of its impact on employee attitudes, behaviors, and especially performance is needed. The present meta-analysis included 51 independent samples (representing a total of N = 12,567 employees) that met the inclusion criteria. The results indicated the expected significant positive relationships between PsyCap and desirable employee attitudes (job satisfaction, …

Asset Performance Evaluation With Mean-Variance Ratio, Zhidong Bai, Kok Fai Phoon, Keyan Wang, Wing-Keung Wong

Research Collection Lee Kong Chian School Of Business

Bai, et al. (2011c) develop the mean-variance-ratio (MVR) statistic to test the performance among assets for small samples. They provide theoretical reasoning to use MVR and prove that our proposed statistic is uniformly most powerful unbiased. In this paper we illustrate the superiority of our proposed test over the Sharpe ratio (SR) test by applying both tests to analyze the performance of Commodity Trading Advisors (CTAs). Our findings show that while the SR test concludes most of the CTA funds being analyzed as being indistinguishable in their performance, our proposed statistics show that some funds outperform the others. On the …

A Meta-Analysis Of The Antecedents Of Voluntary Turnover In Studies Involving Active Duty Military Member Populations, Christy A. R. Licklider

Theses and Dissertations

Studies have explored the antecedents to turnover in the military; however, results vary. This research used a meta-analytic method to evaluate reported correlations between antecedents of turnover intent and turnover in an effort to understand the true relationship between them and offer insight to leaders as to where they can affect turnover within their organizations. Included studies reported a military sample and were published between 1973 and 2009. The meta-analysis revealed no correlation between OPTEMPO and turnover intent. Not enough studies were included to evaluate the relationship between OPTEMPO and turnover. Varying definitions and measurements of OPTEMPO raised concern. Additional …

Leadership & Organizational Change, Terri A. Scandura Phd, Monica Sharif

Management Faculty Articles and Papers

In recent years, change has occurred within almost all organizations. Downsizing, relocations, restructuring, technological changes, mergers, process-oriented changes and people-oriented changes are happening on a daily basis. Therefore it is necessary to study the influence organizational change has on important organizational variables. We conducted a study examining reactions to different types of organizational change. We specifically looked at the extent to which employees trust their organization during different types of organizational change.

A Multilevel Examination Of Proactive Work Behaviors: Contextual And Individual Differences As Antecedents, Travis P. Searle

Department of Agricultural Leadership, Education, and Communication: Dissertations, Theses, and Student Research

In this study, the process through which individual differences (i.e., proactive personality, psychological empowerment, and servant leader characteristics at level-1) and contextual differences (i.e., servant leadership characteristics at level-2) are antecedents to proactive work behaviors (i.e., problem prevention, individual innovation, voice, and taking charge) was tested. Results indicated that psychological empowerment partially mediated the relationship between proactive personality and individual innovation. Psychological empowerment fully mediated the relationship between proactive personality and taking charge. Proactive personality was indirectly related to problem prevention, via psychological empowerment. Psychological empowerment was directly related to voice. In addition, servant leader characteristics at level-1 were positively …

The Great Recession And Its Effect On Small Businesses And Unemployment Rates, Alyssa Sharples

Honors Theses

The 2007 financial crisis, otherwise known as the "Great Recession," has impacted the economy tremendously in the past three years. Businesses have been drastically impacted, as have the lives of workers in the United States. Many articles have been published about different aspects of the recession. One question that has not been completely addressed is how the Great Recession has affected small businesses and unemployment rates. The reason for addressing these two topics is because they are closely related to one another. Small business owners are reporting that there has been a decline in sales. Consumers are not willing to …

Businesses Going Green: An Analysis Of The Factors That Motivate Firms To Adopt Environmentally Friendly Practices, Emma Currin

Honors Theses

The purpose of this analysis is not to degrade environmentally friendly efforts by firms, but rather to explore their motivations for adopting such sustainable initiatives. Current research would suggest that businesses are motivated to adopt environmentally friendly practices by a combination of legal requirements, corporate social responsibility, and gaining some sort of businesses advantage such as reduced costs, increased market share, and similar financial benefits. Determining what it is that contributes to a firm's decision making process can have several positive implications. It may help a firm to better address the changing needs of an evolving society, the government to …

Uncovering Hidden Profiles; Managerial Interventions For Discovering Superior Decision Alternatives, Brian D. Waddell

Honors Projects in Management

A common reason for the use of teams in organizations is the idea that each individual can bring a unique perspective to the decision task; however, research shows that teams often fail to surface and use unique information to evaluate decision alternatives. Under a condition known as the hidden profile, each member uniquely possesses a critical clue needed to uncover the superior solution. Failure to share and adequately evaluate this information will result in poor decision quality. In order to mitigate this team decision-making bias, the present study utilizes experimental research to examine the impact of the devil’s advocacy technique …
