This study presents a structural equations model that represents relationships between department chairs’ social intelligence (SI) and their creative performance (CP) at a public university in the United States. SI was defined as the ability to be aware of relevant social situations, to manage situational challenges effectively, to understand others’ concerns and feelings, and to build and maintain positive relationships in social settings. Four components of SI were examined: situational awareness, situational response, cognitive empathy, and social skills. The model was tested with questionnaire data from 406 faculty members belonging to 43 departments in a state university. The data analyses …

What do Donald Trump, Mark Zuckerberg, Oprah Winfrey, Richard Branson and Jeff Bezos have in common? They are not only CEOs and living icons of the brands they created but also brands themselves. There are many reasons why CEOs today get more attention than in the past. When the media are looking for a business story they often turn to CEOs or founders. Some companies are larger than countries in terms of number of citizens or employees or in revenue. For example, Walmart has about 2.2 million employees, comparable to the population of Qatar, Namibia, or Slovenia, and its revenues …

The Small Business Administration (SBA) supports franchising by backing up loans issued by regular lending organizations. However, the SBA does not directly consider firm strategies as part of its lending process. To appreciate how franchisor characteristics influence franchisee failure, we developed a heuristic model using the methodology and power of predictive analytics. We use multi-year data from the World Franchising Council’s surveys on franchisors’ characteristics and from the SBA on franchisee loan defaults. The data cover 271 diverse US franchise chains that are present in both databases. Our model predicts potential defaults of SBA-backed loans issued to American franchisees and …

In this exercise, students work in teams to narrate stories that describe with rich detail different concepts and theories pertaining to team management in general and virtual team management in particular. The results suggest that students develop a higher level of critical thinking in …
What Do Institutional Investors Know And Act On Before Almost Everyone Else: Evidence From Corporate Bankruptcies, Elena Precourt, Henry Oppenheimer
What Do Institutional Investors Know And Act On Before Almost Everyone Else: Evidence From Corporate Bankruptcies, Elena Precourt, Henry Oppenheimer
Accounting Department Faculty Journal Articles
We analyze investment behavior of institutional managers who hold and trade shares of firms that file for bankruptcy. We find that during the five-year period preceding a bankruptcy filing, institutional investors (except those managing investment companies) are net buyers with a positive abnormal net number of shares traded during the period. Institutional managers start to sell shares of bankrupt firms sooner in some firms than in others; these earlier sales are of smaller firms with weaker operating performance, and lower equity risk. We do not find evidence that institutional stockholders trade strategically and avoid material price declines before they occur.

Information Systems Strategy And The Role Of Chief Information Officers: Strategizing And Aligning Practices, Anna Karpovsky
2015
Information Systems (IS) pose both a challenge and an opportunity for organizations. The topic of strategizing around IS issues is thus of considerable importance. While there has been substantial academic research relating to the strategic value of IS – over 50 years – much of it focuses on such aspects of the topic as strategic IS planning, strategic alignment, and IS for competitive advantage. Fewer studies have taken into account the emergent nature of strategy formation. Fewer still have given attention to strategy-making practitioners, in particular their role and influence in the strategizing process. Accordingly, the goal of this dissertation …

Introduction: The 340B is a federal program that provides eligible rural hospitals, providers, and clinics the capability to purchase medications at reduced prices for outpatient use. Enrollment in the 340B program requires drug manufacturers to supply covered healthcare entities and eligible healthcare organizations medications at substantially reduced prices and has allowed covered entities to extend federal resources by offering more comprehensive services and reaching more of the vulnerable populations. The purpose of this research study was to examine utilization of 340B program within provider based clinics of a university medical school affiliated with a rural hospital to assess the benefits …

Diffusion Of Innovation: Customer Relationship Management Adoption In Supply Chain Organizations, Vicky Ching Gu, Marc J. Schniederjans, Qing Cao
Department of Management: Faculty Publications
The successful diffusion of innovations in rapidly changing supply chain technological environments is essential to support operations and supply chain management functions. In this paper we conceptualize and develop a framework for research into the diffusion of innovations in organizations pertaining to software adoption in supply chain management. Incorporating Task-Technology Fit theory with a network externalities model, we develop a novel approach in customer relations management (CRM) software adoption. An empirical study using Partial Least Squares (PLS) on data from US supply chain managers is utilized to confirm the usability of the proposed framework as well as confirming the efficacy …

Construction Of Entrepreneurial Orientation: Dispute, Demand, And Dare, Vishal K. Gupta
New England Journal of Entrepreneurship
Invited editorial by Vishal K. Gupta, discussing the concept of entrepreneurial orientation (EO). Stated succinctly, entrepreneurial orientation (EO) refers to specific aspects of an organization-wide proclivity toward new endeavors. After about four decades of research on this topic, EO has emerged as a predominant construct of interest in strategic management. Over the years, a large—and growing—body of research has accumulated about EO, but questions do persist about the way(s) in which the various facets of EO are linked to each other. This essay distinguishes between three ways in which the various entrepreneurial elements can be combined to form the overall …

Phone Selection Through Data Envelopment Analysis, Elissa R. Turpin, Adam Sanchez
Undergraduate Review
Today’s digital era has increased the competition for smart devices tremendously, especially in the mobile phone industry. Each manufacturer is trying to out perform its competitors; therefore these phones are being created with a large amount of attractive features. It is important for consumers to understand these different features while comparing phones to choose the one the best suits his or her own needs. In this paper, we present the findings that compared eight different phones using Data Envelopment Analysis (DEA). Features such as weight, battery power, standby time, and megapixels were considered as outputs, where as the retail price …

Exploring The Solar Pv Industry: A Survey Of Pv Manufacturers In China, Patrick E. Prince, Bingqing Zheng
Undergraduate Review
China’s photovoltaic (PV) manufacturing industry has grown significantly since 2000, from being almost nonexistent to providing over 50% of the market share of solar panels in 2012. However, due to the high tariff resulting from an anti-dumping investigation by the US and a shrinking export market, Chinese PV manufacturers are faced with a large amount of challenges. This paper investigated 1) the general issues influencing the success of this industry; 2) the current market channels and the advertising methods; 3) the comparison of supports from government and utility between desired and perceived; 4) the attitude of manufacturers towards external opportunity …

Purchasing Efficiency Measurement Of Selected Chinese Pv Panels Using Data Envelopment Analysis (Dea), Bingqing Zheng, Patrick E. Prince
Undergraduate Review
As a renewable energy generation, the solar Photovoltaic (PV) system has become a popular technique that converts sunlight to generate electrical power. However, most countries, especially like China met challenges in expanding their domestic market and widespread adoption by their own citizens. One of the major reasons why customers are hesitated to adopt solar panels is the difficulty in comparing a variety of solar panels with respect of multiple different dimensions without the aid of appropriate quantitative models. The PV panel’s purchasing efficiency is determined not only just by those technical factors identified by the current literature and practice, but …

Due to the high failure rates of restaurants in the United States, many studies have come up with various reasons to explain the underlying causes of such a phenomenon. One key study by Parsa (2005) suggests, “Restaurant failures have been attributed to economic and social factors […]” and “Restaurant failures can be studied from economic, marketing, and managerial perspectives.” In particular, lack of capital is a major contributing factor for restaurants failure and researchers agree that a restaurant without a sufficient amount of capital will not survive because of three major expenses: overhead, labor, and food cost. Today’s service industry …

Robins Case Network
The crass Irish CEO of Ryanair presides over a modern miracle. Ryanair, with its ridiculously low prices and poor reputation for service, has become one of Europe’s largest and most successful airlines. Employees pay for their own training, flights are cancelled if they won’t be full enough to be profitable, and the concept of “no frills” is heartily embraced. However, some new competitors have come on the scene, and Ryanair may be forced to improve its service and reputation to keep up.

Strategy and Operations Faculty Publications
Although much has been written about how to manage individual projects, there is still little guidance on how to evaluate the “quality” of project portfolio management itself, that is, the degree of “accomplishment” of the process by which the project portfolio is formed and run. This study addresses this gap by employing a qualitative approach to uncover managerial perceptions about what is encompassed by project portfolio management and how the this construct should be evaluated. By building from a review of the scant literature on project portfolio management, conversations with expert scholars on project management, interpretations provided by managers, and …

Selection Of Inflatable Bounce Houses Using Data Envelopment Analysis, Janice Bowen, Rebecca Uboldi
Undergraduate Review
The decision to purchase one consumer product over another is becoming more challenging as the choices that are made available to consumers have increased. This research studies the decision making process when consumers purchase an inflatable bounce house. In addition to cost, a variety of features such as structure size, weight capacity, weight of product, customer ratings, and the number of customer ratings must be compared. It is difficult to make a direct comparison of each of these individual features through traditional methods. As a result, Data Envelopment Analysis is used to compare the outputs and inputs to determine which …

Management and Organizational Studies Publications
Though dissatisfied with some management practices and working conditions, like most high-tech knowledge workers, videogame developers remain reluctant towards unionization. This article examines the factors of collective action among developers as an example, using data gathered from an international survey and interviews. We conclude that developers meet some conditions conducive to collective action but face many obstacles as well, both to collective action and to unionization proper. This does not lead us to share the belief of a decline in collective action, but rather raises the issue of conflating union action and collective action. Our study reveals how unsuited the …

This study examines the effect of work hour congruence on employee job satisfaction and absenteeism using a large, longitudinal sample from the Canadian Workplace and Employee Survey (WES). An employee is said to have work hour congruence when they actually work the number of hours that they desire. Results indicate a difference between employees who desire more hours and those who desire fewer hours: employee desire for and receipt of more hours was related to positive changes in job satisfaction, while employee desire for and receipt of fewer hours was related to reduced absenteeism. In addition, the results suggest that …

2010-2016 Archived Posters
Depending on their needs for enhancing and sustaining their business and market values, some firms choose to operate with a corporate governance structure of CEO duality, in which an executive serves as the CEO and the chairperson of the board of directors. This study used multiple regression data analyses of financial indicators from 146 U.S. not-for-profit hospitals selected from the Office of Statewide Health Planning and Development database of California, for the period from 2009 to 2012. The results of this study suggested CEO duality and presence of physicians on healthcare governance were not related to financial performance of not-for-profit …

Researchers have examined the multiple dimensions of unemployment. Performance rates had declined significantly in a majority of CR 5 states in the 3-year period, 2007-2009. What was not known, however, was the effectiveness of the public administration practice in individual state employment agencies when addressing the economic crisis and rising unemployment. In this evaluative study, the effectiveness of each of 10 state employment agencies in the Central Region 5 of the U.S. Department of Labor Employment and Training Administration was investigated.

How Can Business Analytics Induce Creativity: The Performance Effects Of User Interaction With Business Analytics, Tarek Soukieh
ETD Archive
Most organizations today use business analytics systems mainly for efficiency; reducing cost by contacting the right customer, generating revenue by reducing churn, etc. Nevertheless, business analytics holds promise in generating insights and in making users more creative in their decision making process.
Analytics technology is becoming sophisticated with very advanced technical capabilities. However, behavioral aspects (i.e. user interaction) of using business analytics software have not reached the same level of sophistication. Very little research in this field discusses how to implement analytical systems and what outcomes will it produce.
We are looking at conditions that can enhance user interaction with …

Wide ranges of organizations are explicitly rejecting the norms of rational bureaucracy in designing and running their organizations. Grounded in a qualitative study of those organizations, this paper seeks first to identify some common structural commonalities, and differentiate them from the traditional hierarchies, and second to develop a theoretical framework for understanding them and assess the way they foster internal commitment for desired purpose. We interviewed 61 individuals from 12 organizations in diverse sectors and different geographic locations. We discovered emergent novel forms and practices. We developed a conceptual framework to capture the main discoveries, not as models of perfection, …
