Modeling Social Transmission Dynamics Of Unhealthy Behaviors For Evaluating Prevention And Treatment Interventions On Childhood Obesity, Leah M. Frerichs, Ozgur M. Araz, Terry T.-K. Huang

Department of Supply Chain Management and Analytics: Faculty Publications

Research evidence indicates that obesity has spread through social networks, but lever points for interventions based on overlapping networks are not well studied. The objective of our research was to construct and parameterize a system dynamics model of the social transmission of behaviors through adult and youth influence in order to explore hypotheses and identify plausible lever points for future childhood obesity intervention research. Our objectives were: (1) to assess the sensitivity of childhood overweight and obesity prevalence to peer and adult social transmission rates, and (2) to test the effect of combinations of prevention and treatment interventions on the …

Quantitative Analysis Of Impacts Of Employee Engagement On Continuance And Normative Commitment, Daniel A. Cernas Ortiz, Hong Qin, Wai Kwan (Elaine) Lau

Accounting Faculty Research

A positive relationship between employee engagement and affective commitment is already documented in the literature. However, we do not adequately know how engagement is associated with continuance and normative commitment. Using survey methodology we find that while engagement has a non–significant positive association with continuance commitment; it has a positive association with normative commitment. No negative association was found between engagement and continuance commitment. These results advance prior findings about the effect of employee engagement on different types of commitment and provide understandings in setting effective performance standards in the organization.

Faculty Usage Of Social Media And Mobile Devices: Analysis Of Advantages And Concerns, D. Roebuck, S. Siha, R. L. Bell

Faculty Articles

This study seeks to understand the perceptions of professors using social media (also called Web 2.0 tools) in the classroom, what kinds of mobile devices are used to access the social media used, and what drives individuals to use them. In addition, it seeks to identify the advantages and concerns faculty has with the use of social media for classroom instruction. Two-Way Multivariate Analysis of Variance (MANOVA) procedure was used to ascertain whether differences existed between two dependent variables and (a) gender, (b) different academic ranks, and (c) gender *rank to determine if there are any interaction effects between genders …

An Easy Method To Introduce Mirr Into Introductory Finance Classes, Tom Arnold, Terry D. Nixon

Finance Faculty Publications

In this paper, the modified internal rate of return (MIRR) is demonstrated to be a holding period return calculation that is not dependent on knowing a project's internal rate of return (IRR) nor the process for finding the IRR. Further, the MIRR calculation can be directly connected to the calculation of the profitability index (PI) and the net present value (NPV) if project cash flows are discounted using a firm's weighted average cost of capital. This connection to the PI and NPV allows for an intuitively appealing presentation of the MIRR calculation.

The Quandary Of Assessing Faculty Performance, K. Fatehi, M. Sharifi, J. Herbert

Faculty Articles

Many educators assert that the continued use of student ratings of teaching effectiveness does not improve learning in the long run. However, administrators continue to use student opinions regarding teaching effectiveness because of its convenience and the quantitative nature of the measurement. Reducing a very complex phenomenon to a very simple numeral has its appeal. In this paper we discuss a related aspect of teaching assessment, namely the variations of skills among instructors and the students’ response to the same. In doing so, we suggest pragmatic guidelines to university administrators for evaluating various levels of skills and performance.

Conflict Management Between Employees From Different Departments : Contribution Of Organizational Identification And Controversy, Taohong Zhu

Lingnan Theses

Synthesizing theories of social identity, goal interdependence, and conflict management, this study built and tested a theoretical model in which interdepartmental goal interdependence affects conflict outcomes between different departments through constructive controversy (i.e. the open-minded discussion for mutual benefit) dynamics adopted by employees from different departments in the organization. This study also proposes that organizational identification moderates the link between interdepartmental goal interdependence and constructive controversy.

An interview sample of 129 employees from various business organizations and diverse industries in mainland China described and rated a critical incident when they had a conflict with their coworker from another department in …

A Systematic Approach To Manage Missing Data In Pavement Management Systems, Mazin M. Al-Zou'bi

Open Access Theses & Dissertations

Pavements are an important part of the highway transportation infrastructure, accounting for the largest share of the overall investment. A tremendous amount of time and money is spent each year on the construction of new pavements, as well as on the maintenance and rehabilitation of existing pavements.

Transportation agencies use pavement management systems (PMS) for their maintenance and rehabilitation planning, programming, and budgeting. PMS are used to make decisions regarding when maintenance and rehabilitation should be applied. The systems also select what type of treatment should be applied for each pavement section in the network with clear estimations of the …

Supply Chain Management: Impact Of Customer Relationship Marketing On Performance Under Cooperation And Competition Strategies, Maria Eugenia Barua

Open Access Theses & Dissertations

The dissertation investigation proposes a modified supply chain management model that is grounded on marketing theory and the concept of production sharing. Specifically, the model challenges the traditional cooperation-conflict continuum of strategic marketing management with a new managerial approach based on a cooperation-competition continuum. I investigate the significance of the new model in explaining behaviors in the supply chain management and its performance. In addition, I investigate whether the proposed managerial continuum (cooperation-competition) is consistent with other behaviors including power, conflict, trust, and customer relationship marketing such that coordination and supply chain performance is enhanced.

Coordinating A Supply Chain With A Manufacturer-Owned Online Channel: A Dual Channel Model Under Price Competition, Jennifer K. Ryan, Daewon Sun, Xuying Zhao

Department of Supply Chain Management and Analytics: Faculty Publications

We consider a dual channel supply chain in which a manufacturer sells a single product to end-users through both a traditional retail channel and a manufacturer-owned direct online channel. We adopt a commonly used linear demand substitution model in which the mean demand in each channel is a function of the prices in each channel.We model each channel as a news vendor problem, with price and order quantity as decision variables. In addition, the manufacturer must choose the wholesale price to charge to the independent retailer. We analyze the optimal decisions for each channel and prove the existence of a …

Participation In Decision Making As A Property Of Complex Adaptive Systems: Developing And Testing A Measure, Ruth A. Anderson, Donde Plowman, Kirsten Corazzini, Pi-Ching Hsieh, Hui Fang Su, Lawrence R. Landerman, Reuben R. Mcdaniel

Department of Management: Faculty Publications

Objectives. To (1) describe participation in decision-making as a systems-level property of complex adaptive systems and (2) present empirical evidence of reliability and validity of a corresponding measure. Method. Study 1 was a mail survey of a single respondent (administrators or directors of nursing) in each of 197 nursing homes. Study 2 was a field study using random, proportionally stratified sampling procedure that included 195 organizations with 3,968 respondents. Analysis. In Study 1, we analyzed the data to reduce the number of scale items and establish initial reliability and validity. In Study 2, we strengthened the psychometric test using a …
