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, …

Depicting Estimates Using The Intercept In Meta-Regression Models: The Moving Constant Technique, Blair T. Johnson Dr., Tania B. Huedo-Medina Dr.

Blair T. Johnson

In any scientific discipline, the ability to portray research patterns graphically often aids greatly in interpreting a phenomenon. In part to depict phenomena, the statistics and capabilities of meta-analytic models have grown increasingly sophisticated. Accordingly, this article details how to move the constant in weighted meta-analysis regression models (viz. “meta-regression”) to illuminate the patterns in such models across a range of complexities. Although it is commonly ignored in practice, the constant (or intercept) in such models can be indispensible when it is not relegated to its usual static role. The moving constant technique makes possible estimates and confidence intervals at …

On Uncertainty, Ambiguity, And Complexity In Project Management, Michael T. Pich, Christoph H. Loch, Arnoud De Meyer

Arnoud DE MEYER

This article develops a model of a project as a payoff function that depends on the state of the world and the choice of a sequence of actions. A causal mapping, which may be incompletely known by the project team, represents the impact of possible actions on the states of the world. An underlying probability space represents available information about the state of the world. Interactions among actions and states of the world determine the complexity of the payoff function. Activities are endogenous, in that they are the result of a policy that maximizes the expected project payoff.

Front Line Hospitality Leaders: Knowledge, Knowledge Acquisition, And Ability To Effectively Lead, Gregory Scott Krawiec

Gregory Scott Krawiec

The successful practice of leadership involves a considerable amount of time, effort, and knowledge. The hospitality industry is service intensive and requires leadership effectiveness. Understanding the front line leader's knowledge and its source, ability to apply the knowledge, and time allotted in the work environment to utilize this knowledge is of great importance to future hospitality leadership research. Although leaders exhibited negligible knowledge about leadership and indicated very little familiarity with leadership theory and concepts, all communicated standard thoughts about leadership traits and characteristics. However, hospitality leaders do not model the behaviors and skills they list as being characteristic of …

State Space Modelling Of Dynamic Choice Behavior With Habit Persistence, Kang Bok Lee

Doctoral Dissertations

In this dissertation, I present a new approach to capturing dependence across time in dynamic choice data. To achieve this, I develop a state space dynamic choice model and a novel algorithm to fit the data. Instead of capturing dependence in outcomes through lagged response variables, referred to as state dependence, I introduce a lagged utility term through the latent state equation. The lagged utility term captures habit persistence, which has not been explored directly in earlier models (Heckman, 1981b). The autoregressive nature of the lagged utility provides a significantly richer summary of prior utility than a lagged outcome variable. …

Heuristic Rules In The Field: Evidence From Royalty Shares In Scientific Teams, Reddi Kotha, Dan Lovallo

Research Collection Lee Kong Chian School of Business

Using field data from a large U.S. technology transfer organization with over $50 million in annual revenue, we investigate four related issues regarding the sharing of licensing revenues by academic teams. First, we find that the main empirical regularity is a heuristic-based allocation of shares 1/n, equal shares to all unique inventors in a single invention team, and the use of the partition dependence (PD) rule, whereby inventors receive equal share within an invention and shares across inventions included in the same contract are equal. Second, when we examine the performance consequences of such equal sharing, we find it is …

Can I Smile With Spirit? Towards A Process Model Associating Workplace Spirituality And Emotional Labor, Ashwini Gangadharan

This dissertation presents workplace spirituality as an organizational intervention to manage the problem of emotional labor and its dysfunctional consequences among the service employees.

The main thesis of the dissertation is that workplace spirituality will enable service employees to appraise emotional labor as a positive stressor (challenge stressor) rather than a negative stressor (hindrance stressor). The …

Cross-Cultural Study Of Channel Relationship Factors - Antecedents Of Satisfaction In A Retail Setting: A Commentary Essay, Sudhir H. Kale

Sudhir H. Kale

Channel relationships within and across diverse markets have been investigated for quite some time. Yet findings from these studies over the last forty years or so have been far from conclusive. Channel researchers Runyan, Sternquist, and Chung (forthcoming) investigate interrelationships between the behavioural constructs of role performance, dependence, conflict, satisfaction, and influence strategy in the U.S. and Japanese context. Reading this paper leads credence to the adage, 'The more things change, the more they stay the same.' Indeed, a review of representative comparative channels research literature from the 1980s and post-2000 brings to surface striking similarities in terms of shaky …

Integrating Simulation Modelling And Value Stream Mapping For Leaner Capacity Planning Of An Emergency Department, Esmat Swallmeh, Ayman Tobail, Waleed Abo-Hamad, James Gray, Amr Arisha

Conference papers

Recently, the application of lean thinking in healthcare has grown significantly in response to rising demand, caused by population growth, ageing and high expectations of service quality. However, insufficient justifications and lack of quantifiable evidence are the main obstacles to convince healthcare executives to adopt lean philosophies. This paper presents a real application of the successful implementation of a methodology that integrates Value Stream Mapping (VSM) and simulation modelling to improve an emergency department (ED) of a University hospital in Dublin. Appling lean approach in operations will minimize the patient waiting time and improve service time. VSM points out to …

Optimal Diet Selection And The Compliance Problem: A Technical Note, Munirul Nabinl, Sukanto Bhattacharya, Kuldeep Kumar

Kuldeep Kumar

In this paper we have posited an alternative methodology for the least-cost diet selection problem subject to a given set of nutritional constraints. In order to better address the implicit compliance problem, we have re-cast the classical diet selection problem using a two-stage approach whereby in the fi rst stage the dietician decides on the total number of least-cost combinations which satisfy the nutritional requirements and in the second stage, the dietician finds the optimal number of diet plans that have to be formulated. The second stage basically involves finding a reduced search space n* out of which the dietician …

Success Mass Customization: The Role Of Market Segment Favorableness, Wai Kwan (Elaine) Lau

Wai Kwan (Elaine) Lau

Mass customization (MC) emerged as a new paradigm that shifted from mass production. It achieves both volume and cost efficiency of mass production and customization capabilities at the same time. The challenge for manufacturing managers is to find ways to cope with the market and increase product variety through MC without affecting lead-time, cost or quality. Based on the previous literature review, a conceptual summary of MC is discussed. According to the conceptual summary, a model is built to discuss how each of the elements associated with MC contributes to improved firm performance. It further proposed that the market segment …

The Impacts Of Personality Traits And Goal Commitment On Employees' Job Satisfaction, Wai Kwan (Elaine) Lau

Wai Kwan (Elaine) Lau

The present research investigates the effects of personality traits, such as self-efficacy and locus of control, on job satisfaction. It also examines the mediating impact of goal commitment on relationships between personality and job satisfaction. The results indicate that both self-efficacy and locus of control are positively associated with goal commitment. In addition, locus of control is found positively related to job satisfaction. However, self-efficacy does not have the same positive relationship with job satisfaction. The study further confirms the mediating effect of goal commitment on relationships between personality traits and job satisfaction.

The Effects Of Leadership Style On Employee’S Perception Of Justice: The Role Of Employee’S Participation, Wai Kwan (Elaine) Lau

Wai Kwan (Elaine) Lau

The present research examines the effect of leadership style (classical, transactional, transformational, and dynamic) and employee’s participation on employee’s perception of justice (distributive, procedural, and interactional justice). It is proposed that different leadership styles are expected to display different effects on employee’s participation and perceptions of justice. Moreover, employee’s participation in decision making process is predicated to positively influence his/her perception of justice.

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

Wai Kwan (Elaine) Lau

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.

This study examines the relationship between organizational learning capabilities and alliance performance. The concept of organizational learning capabilities in this study is developed comprising training availability, technical expertise, and alliance experience. It proposes that a greater alliance learning capability is positively related to alliance goal achievement. The research further investigates how the inter- and intra-firm mechanism, the average level of technical expertise and alliance experience, and the gap of technical expertise and alliance experience between the partners impact alliance objectives.

The Effect Of Employee Engagement On Continuance And Normative Commitment To The Organization, Wai Kwan (Elaine) Lau

Wai Kwan (Elaine) Lau

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. This study’s results support recent critiques to Allen and Meyer’s three-dimensional model of organizational commitment.

The Effects Of Leadership Style And Employee’S Participation On Perceived Justice, Wai Kwan (Elaine) Lau

Wai Kwan (Elaine) Lau

The present study proposes and tests a model that examines the relationship between leadership style, employee’s participation, and justice perceptions. Results indicate that transactional, transformational, and dynamic leadership have positive impact on distributive, procedural, and interactional justice. Moreover, the effect of leadership style on organizational justice was indirect through employee’s participation. There are also some interesting differences across different types of leadership style and justice.

A Study Of Effective Leadership In The Chinese Context, Wai Kwan (Elaine) Lau

Wai Kwan (Elaine) Lau

The study of leadership is one of the most often researched management topics. However, most research and theory contributions are to a great extent limited to accounting for leadership practice in the West. This study is designed to develop an effective leadership model that works in the Chinese context. Paternalistic leadership, a dominant leadership style in an Eastern business environment, is compared with transformational leadership, a dominant leadership style in a Western business environment. In addition, the cultural differences between China and the West relating to leader-follower relationships suggest different leadership behaviors may be more effective in one of these …

Multi-Criteria Decision Modeling For Best Value Selections In Target Value Design Integrated Project Delivery, Brent Patrick Griffis

Master's Theses

Integrated Project Delivery (IPD) combined with Target Value Design (TVD) is a better way to deliver value for the client than traditional guaranteed maximum price (GMP) methods. With traditional GMP delivery methods, the interests of the parties are often at odds. The goal of IPD is to align all party interests in order to achieve a win-win scenario. Due to the aligning nature of IPD and the fact that each party’s success is dependent on achieving the project objectives as a whole; a non-biased, transparent, decision-making process is necessary in order to deliver the project objectives within the constraints of …

Models Using The Benefits Of Cross Training Policies To Tackle Nurse Shortage Crisis, Jomon Paul, Leo Macdonald

Leo MacDonald

This paper seeks to offer insight into cross training strategies that could be effective in aiding in alleviating the nurse shortage issue and its potential to negatively impact on patient safety and mortality. We develop optimization models to evaluate the benefits of cross-training, in particular chaining practices, on nurse workforce planning under stochastic demand, and determine the optimal allocation of both regular and cross-trained staff at a minimum cost. We demonstrate the benefits of cross-training in terms of a reduction in the total number of nurses required to satisfy demand across multiple departments as well as from an economic (i.e. …

A Model To Study Disparities And Lifetime Medical Costs, Jomon Aliyas Paul, Leo Macdonald, Govind Hariharan

Leo MacDonald

We develop a mathematical model that captures the complex interactions within the health service system featuring chronic diseases and provides valuable lessons that could assist in controlling escalating healthcare costs. We utilize a Monte Carlo simulation framework to simulate the evolution of a population subject to deaths, births, and disease conditions. The model estimates the lifetime health expenditures of individuals based on demographics including race, age, and gender, as well as risk factors that contribute to the development of specific disease conditions. We further incorporate interactions between multiple disease conditions and the effect of risk factors in chronic disease incidence …
