Establishing A Benchmark Of Fuel Efficiency For Commercial Airline Operations, Samuel Chandra, Chetan K. Chitgopeker, Ben Crawford, John Dwyer, Yi Gao

Journal of Aviation Technology and Engineering

Fuel efficiency is vital for commercial airlines as fuel is one of the most costly items for airline operations. This study aims to compare fuel efficiencies of selected airlines around the globe and to build a benchmark of fuel efficiency that can be referred to by airlines. By using data on fuel consumption and traffic output collected from various sources including airline annual reports, environmental reports and sustainability reports, this study calculated fuel efficiencies measured by liters of fuel consumed per revenue tonne kilometer (RTK) for the selected airlines in the calendar year 2011 or financial year 2010–2011. Airlines were …

Capacity Planning With Financial And Operational Hedging In Low‐Cost Countries, Lijian Chen, Shanling Li, Letian Wang

MIS/OM/DS Faculty Publications

The authors of this paper outline a capacity planning problem in which a risk-averse firm reserves capacities with potential suppliers that are located in multiple low-cost countries. While demand is uncertain, the firm also faces multi-country foreign currency exposures. This study develops a mean-variance model that maximizes the firm’s optimal utility and derives optimal utility and optimal decisions in capacity and financial hedging size. The authors show that when demand and exchange rate risks are perfectly correlated, a risk- averse firm, by using financial hedging, will achieve the same optimal utility as a risk-neutral firm. In this paper as well, …

Entrepreneurial Orientation And International Scope: The Differential Roles Of Innovativeness, Proactiveness, And Risk-Taking, Li Dai, Vladislav Maksimov, Brett Anitra Gilbert, Stephanie A. Fernhaber

Scholarship and Professional Work - Business

This research integrates the international business and entrepreneurship literatures by examining the independent influences of innovativeness, proactiveness, and risk-taking on the ability of a firm to broaden its scope across international markets. For each dimension of entrepreneurial orientation, a cost–benefit framework is applied to highlight the trade-offs associated with different levels in the internationalization context. Based on a unique dataset of 500 SMEs spanning 10 industries, the results reflect the consequences of being “stuck in the middle” with respect to their strategic posture on innovativeness and proactiveness, but reveal a nuanced role for risk-taking behavior. The non-uniform and non-linear relationships …

When Do Domestic Alliances Help Ventures Abroad? Direct And Moderating Effects From A Learning Perspective, Hana Milanov, Stephanie A. Fernhaber

Scholarship and Professional Work - Business

While the importance of strategic alliances for new venture internationalization is well acknowledged, the effect of domestic partners remains less understood. Building on organizational learning theory's vicarious learning arguments, we suggest that internationally experienced domestic partners positively influence new ventures' international intensity. Moreover, acknowledging that ventures may have multiple learning sources, we argue that the effect is more pronounced when substituting for the lack of new ventures' top management teams' international experience, or when complementing the insights about foreign markets received from foreign alliance partners. The analysis of 194 publicly held new ventures largely supports our hypotheses.

Developing A Method For Measuring "Working Out Loud", Dennis E. Pearce

Theses and Dissertations--Finance and Quantitative Methods

Enterprise social network software platforms (ESNs) are increasingly being deployed in firms across almost every industry as a means of fostering employee collaboration. Although benefits in increased productivity, innovation, and employee engagement are highly touted, there is a high failure rate of these deployments. This often occurs because (1) there is a misapplied focus on technology adoption rather than adoption of the employee behaviors that are ultimately required to obtain those benefits, and (2) it is unclear what those behaviors are and how to measure them.

“Working Out Loud” is one possible framework for understanding and measuring the behaviors necessary …

Impact Of Authentic Leadership On Performance: Role Of Followers’ Positive Psychological Capital And Relational Processes, Hui Wang, Yang Sui, Fred Luthans, Danni Wang, Yanhong Wu

Department of Management: Faculty Publications

Authentic leadership has received considerable attention and research support over the past decade. Now the time has come to refine and better understand how it impacts performance. This study investigates the moderating role followers’ positive psychological capital (PsyCap) and the mediating role that leader–member exchange (LMX) may play in influencing the relationship between authentic leadership and followers’ performance. Specifically, we tested this mediated moderation model with matched data from 794 followers and their immediate leaders. We found that authentic leadership is positively related to LMX and consequently followers’ performance, and to a larger degree, among followers who have low rather …

Open-Minded Discussion In Interdepartmental Collaboration : Contribution Of Goal Interdependence And Social Motives, Jiewei, Antonia Lu

Lingnan Theses

Combining theories of social motives, goal interdependence, and conflict management, this study theorized a model in which interdepartmental goal interdependence affects conflict outcomes between different departments through open-minded discussion dynamics adopted by employees from different departments in the organization. This study also proposes that social motives moderate the link between inter-departmental goal interdependence and open-minded discussion.

A sample of 133 employees from different business organizations in China were interviewed to recall a critical incident when they had a conflict with their coworker from different departments. SEM results and other analysis results support the hypotheses that cooperative interdepartmental goal interdependence and …

Direct-To-Consumer Advertising Of Drugs And Patients' Health Care Seeking Behaviors, Patricia Elaine Kennedy-Tucker

Walden Dissertations and Doctoral Studies

Known as direct-to-consumer advertising (DTCA), pharmaceutical companies in the United States are permitted to advertise prescription drugs directly to consumers. The purpose of this quantitative study was to determine if an association exists between DTCA and health care-seeking behaviors. The theoretical framework for this study involved social learning theory, information integration theory, and prospect theory. The research questions identified if exposure to DTCA (a) is associated with physician office visits, (b) influences a patient/physician conversation regarding a prescription, (c) influences requesting a prescription, and (d) has an impact on patients' ratings of the overall interaction with the physician. Data were …

Employee Locus Of Control And Engagement In Nonprofit Organizations, Jacqueline Myers

Walden Dissertations and Doctoral Studies

Transformational leadership and employee engagement have been studied in the private sector, yet research in the nonprofit sector is scarce. Addressing this gap is important to improve nonprofit practices, as nonprofit organizations contribute to a myriad of social issues critical to positive social change. Using Burns's theory of transformational leadership, which places emphasis on motivating and inspiring performance through a shared vision and mission, the purpose of this quantitative study was to analyze the effects of transformational leadership on employee engagement in nonprofit organizations. The study also assessed whether locus of control acted as a mediating variable on employee engagement. …

Impact Of Middle-Level Managers' Well-Being And Happiness On Direct Reports' Performance, Respent Green Iii

Walden Dissertations and Doctoral Studies

The happy productive worker (HPW) theory states that happy employees perform at higher levels than unhappy employees do. Despite the explanatory power of the HPW theory, it was unknown if a happy middle-level manager would be associated with productive direct reports. The purpose of this phenomenological study was to address that gap by exploring the impact of middle-level managers' well-being and happiness on the performance of their direct reports. Key research questions examined how middle-level managers' well-being and happiness influenced the performance of their direct reports and how middle-level managers' application of the HPW theory influenced social change. Twenty middle-level …

Talent Retention In Organizations Facing Staff Reductions Via Layoffs, George Edward Lightfoot

Walden Dissertations and Doctoral Studies

High voluntary attrition threatens the future of downsizing organizations. The purpose of this phenomenological study was to explore how employee layoff announcements reduces the perception of organizational commitment to experienced, skilled workers in central Wisconsin. The conceptual framework integrated stress response theories including Cannon's cognitive activation theory of stress. Face-to-face interviews were conducted with 20 journeyman level artisans who had witnessed the layoff process within 50 miles of Wausau Wisconsin. These interviews were analyzed via the modified van Kaam method to code, cluster, and group the findings into significant themes. Nine themes emerged from the analyses suggesting layoff implementation strategies …

Using Fair Division Methods For Allocating Transportation Funds, Edith Montes

Open Access Theses & Dissertations

Current transportation funding allocation methods are very complex due to limited budgets and conflicting interests. In order to maintain an efficient infrastructure transportation system, agencies must balance the allocation of funds required either to increase the roadway capacity or to preserve the existing roads in service. Depending on the target objectives and specific constraints, the funding allocation process is approached using different methods. The funding allocation process is usually addressed using expert judgment which involves subjective criteria, weighted formulas with pre-established priorities, or a combination of both. However, formula-based funding allocation methods may lead to the public's disagreement if final …

A Social Exchange Perspective: The Mediating Effect Of Customers' Perceived Overall Justice And Affect In The Relationship Between Employee Performance And Customer Satisfaction, Si Hyun Kim

Open Access Theses & Dissertations

Drawing from social exchange theory (Blau, 1964) and affective event theory (Weiss & Cropanzano, 1996), this paper provides insight into how customers' perceived overall justice and customers' affect mediate the relationship between employee performance and customer satisfaction. The primary research question of the study was how employees' performance (task performance and organizational citizenship behaviors) indirectly influences customers' satisfaction. In addition, this study examined the moderating effect of types of exchange in the relationship between employee performance and customers' perceived overall justice. 151 dyadic surveys were collected from both customers and stylists in 5 beauty/hair salons. As expected, customers' positive affect …

The Nature And Influence Of Relationship On Success In A Virtual Work Environment, Carol Locher Ransone

Antioch University Dissertations & Theses

The evolution of technology in the 21st century has led to a greater understanding of the benefits and the challenges of expanding work relationships across geographical boundaries. This expansion has contributed to the development of a global society with over three million employee teleworkers (Global Workplace Analytics and the Telework Research Network, 2013). In spite of the advances in connecting across the globe technologically, the importance of successfully working together in a virtual work environment is grounded in relationships that foster individual growth and group cohesion. The human elements of connectivity are primary to the success of organizations as well …

Sustainability Strategies In Supply Chain Management, Amit Arora

College of Graduate Studies: Theses & Dissertations

Managers no longer view sustainability of organizations only in terms of profitability and economic growth of shareholders. Various competitive pressures are forcing managers to broaden the scope of sustainability to include explicit environmental and societal objectives too. These pressures are emanating from various sources such as depleting natural resources, regulatory policies from governments, erratic weather cycles, demanding customers and brand damage due to exposure about poor working conditions in supplier factories located in other countries. This dissertation consists of three essays that contribute to the practice and literature of strategic sustainable supply chain management by examining its four aspects: measure, …

Two Stage Procurement Processes With Competitive Suppliers And Uncertain Supplier Quality, Yue Jin, Jennifer K. Ryan, Walter Yund

Department of Supply Chain Management and Analytics: Faculty Publications

This paper considers a sourcing problem faced by a manufacturer who outsources the manufacturing of a product to one of several competing suppliers, whose cost and quality capabilities are unknown. We consider a two-stage sourcing process in which the first stage is the qualification stage, while the second stage is the supplier selection stage. In the first stage, the manufacturer exerts effort to learn about the quality level of each of the suppliers and then must determine the set of qualified suppliers, subject to some tolerance for error. In the second stage, the manufacturer runs a price-only procurement auction, in …

A Sociogenomic Perspective On Neuroscience In Organizational Behavior, Seth M. Spain, Peter D. Harms

Department of Management: Faculty Publications

We critically examine the current biological models of individual organizational behavior, with particular emphasis on the roles of genetics and the brain. We demonstrate how approaches to biology in the organizational sciences assume that biological systems are simultaneously causal and essentially static; that genotypes exert constant effects. In contrast, we present a sociogenomic approach to organizational research, which could provide a meta-theoretical framework for understanding organizational behavior. Sociogenomics is an interactionist approach that derives power from its ability to explain how genes and environment operate. The key insight is that both genes and the environment operate by modifying gene expression. …

Uncovering The Nuances Of Referral Hiring: How Referrer Characteristics Affect Referral Hires’ Performance And Likelihood Of Voluntary Turnover, Jenna R. Pieper

Department of Management: Faculty Publications

The literature on employee referral hiring gives little attention to referrers. Synthesizing two theories in the literature (the better match and social enrichment accounts), through the lens of social resources theory, I provide a conceptual and empirical breakdown of the effects of referrer quality (referrer performance at hire and referrer tenure at hire) and post-hire accessibility (referrer employment and referrer-referral hire job congruence) on referral hire performance and likelihood of voluntary turnover. I tested my hypotheses with longitudinal data from 386 referrer-referral hire pairs at the same job level in a U.S. call center over a 2-year period. Across analyses …

Modelling Risk Management In Banks: Examining Why Banks Fail?, Daniel Onyebuchi Okehi

Walden Dissertations and Doctoral Studies

The persistent bank failures in the Nigerian financial system have been a major concern of the government, depositors, shareholders, and the general public because of the important roles banks play in the economy. The aim of this research was to determine why there have been persistent bank failures in Nigeria and to investigate whether ineffective risk management in banks, coupled with poor corporate governance practices and nonadherence to regulations (independent variables), play a significant role in the banks' performance(dependent variable). The variables were operationalized by taking VaR as the proxy for risk management, having CRO as proxy for ERM , …

Influential Leadership In A Diverse Retail Environment: Implications For Reducing Voluntary Employee Turnover, Stuart Jackson

Walden Dissertations and Doctoral Studies

Many investigators have documented the impact of high attrition rates on an organization's ability to deliver its expected results. However, limited information is available regarding the efficacy of a specific bundle of variables, which would support a leader's ability to influence voluntary employee turnover. This quantitative study investigated the effectiveness of a 60-day treatment implemented to address the problem of voluntary employee turnover in a diverse retail environment. The research questions examined the effectiveness of an increase in communication, answering, recognition, and training on voluntary employee turnover and job satisfaction in a diverse retail environment. The theoretical foundation of the …

Prioritizing Offshore Vendor Selection Criteria For The North American Geospatial Industry, Simon Wolfgang Musaeus

Walden Dissertations and Doctoral Studies

The U.S. market for geospatial services totaled US $2.2 billion in 2010, representing 50% of the global market. Data-processing firms subcontract labor-intensive portions of data services to offshore providers in South and East Asia and Eastern Europe. In general, half of all offshore contracts fail within the first 5 years because one or more parties consider the relationship unsuccessful. Despite the high failure rates, no study has examined the offshore vendor selection process in the geospatial industry. The purpose of this study was to determine the list of key offshore vendor selection criteria and the efficacy of the analytic hierarchy …

Academic Analytics In Higher Education: Barriers To Adoption, Willie L. Pomeroy

Walden Dissertations and Doctoral Studies

The analysis of big data points and the use of data analytics have proven successful in improving corporate business efficiencies, growing profits, and increasing competitive advantages. The theory of academic capitalism, which holds that institutions of higher education are becoming more like corporations due to declining operating funds and the need to become more efficient, transparent, and competitive, guided this study. Despite the positive outcomes that analytic tools may produce in advanced efficiencies and competitive growth, college academic administrators have not yet adopted these tools, due in part to barriers facing the administrators. The purpose of this phenomenological study was …

Diffusion Of Social Network Technology And Overuse Among Health Industry Knowledge Workers, Abdel Rahman Toure

Walden Dissertations and Doctoral Studies

Many organizations now realize the important role of social network technology (SNT) in building social capital and hence broadening their customer base. However, observations have indicated that, while working, many knowledge workers use SNT to engage in non-job related activities, potentially leading to a decrease in productivity. The purpose of this study was to examine the relationship between the usage of SNT and productivity in the health sector. The theoretical foundation of this study emanated from Rogers's theory of diffusion of innovations and Campbell, Rodney, Scott, and Christopher's theory of performance. Collection of data involved a self-administered survey designed with …

African American Women's Perception Of Subprime Lending Practices On Their Home Buying Knowledge And Behaviors, John Howard White

Walden Dissertations and Doctoral Studies

The subprime mortgage lending practices from 1995 to 2007 were disproportionately concentrated on minority and low income neighborhoods of the United States. Despite the negative effects of subprime loans, these loans are regaining popularity. The purpose of this phenomenological research study was to bridge the gap in knowledge about their effect on African American women by exploring the home buying knowledge and behaviors of African American women between 2004 and 2007 in a southern state. Ajzen and Fishbein's theory of planned behavior served as the theoretical framework of this study, which explored factors that motivated African American women to buy …
