Communicating Analytic Results: A Tutorial For Decision Consultants, Jeffrey Keisler, Patrick Noonan

Jeffrey Keisler

Good analysis alone may not achieve the goals of decision analysis (DA) engagements. Good communication of the results of that analysis can help stakeholders understand, accept, and implement the recommended course of action. Practitioners can use decision analytic principles when considering the decision of how to communicate results themselves. From this perspective, we consider a range of questions to ask in preparing for communication with the client and other stakeholders. We review standard communication practices in DA engagements. The standard practice can be improved by drawing on insights from other areas of management practice. Decision analysis has both technical and ...

Modelling Innovation Support Systems For Development, Eric Vaz, Teresa Noronha, Purificación Galindo, Peter Nijkamp

Geography Publications and Research

The present article offers a concise theoretical conceptualization on the contribution of innovation to regional development. These concepts are closely related to geographical proximity, knowledge diffusion and filters, and clustering. Institutional innovation profiles and regional patterns of innovation are two mutually linked, novel conceptual elements in this article. Next to a theoretical framing, the paper offers also a new methodology to analyse institutional innovation profiles. Our case study addresses three Portuguese regions and their institutions, included in a web-based inventory of innovation agencies which offered the foundation for an extensive data base. This data set was analyzed by means of ...

A Closer Look At The Assistant (To The) Regional Manager: Personality Differences Between First And Second In Command Leaders In Organizations, Ross Benes

The McNair Scholars Research Journal

Although a great deal of research has established personality differences between leaders and their followers (Lord, de Vader, & Alliger, 1986) there has been little research on how leaders at different levels of organizations may differ from one another. In particular, no research to date has examined whether or not there are personality differences between those who are first in command of their organizations and those second in command. The present study attempts to explore whether or not these differences exist in terms of both lay perceptions and in reality. The researchers in this study asked 401 individuals to contrast the ...

Business Topographies: A Spatiotemporal Analysis Of 150 Years Of Indian Business, Eric Vaz

Geography Publications and Research

One of the most growing entrepreneurial landscapes has been without a doubt in the last decade India. India, with a total population of almost 1.2 billion inhabitants, is a land of immense business opportunity within a highly competitive market. Before the eighties however, India was mainly a rural country, with a large contrast of the nexus between city and periphery. With the emergence of young generation of entrepreneurs, the economy has been growing at a rate of 8-10% for the last 20 years. The share of the service sector has increased to 60 per cent in the total GDP ...

How Can We Improve The Performance Of Supply Chain Contracts? An Experimental Study, Ehsan Elahi, Narasimha Lamba, Chinthana Ramaswamy

Ehsan Elahi

Although optimal forms of supply chain contracts have been widely studied in the literature, it has also been observed that decision makers fail to make optimal decisions in these contract setups. In this research, we propose different approaches to improve the performance of supply chain contracts in practice. We consider revenue sharing and buyback contracts between a rational supplier and a retailer who, unlike the supplier, is susceptible to decision errors. We propose five approaches to improve the retailer’s decisions which are in response to contract terms offered by the supplier. Through laboratory experiments, we examine the effectiveness of ...

Product Bundling: Impacts Of Product Heterogeneity And Risk Considerations, Mehdi Sheikhzadeh, Ehsan Elahi

Ehsan Elahi

Bundling has been extensively studied in the literature and its benefits have been manifested through three perspectives of achieving better price discrimination, helping to save costs, and preserving the power for deterring a potential entrant. In this study, we examine two aspects of bundling which have not been studied before. We examine the impact of product heterogeneity on bundling decisions. We also address risk considerations in a bundling problem. Specifically, we consider a retailer who has the option of selling a bundle of two products (pure bundling policy), or selling the products separately (no-bundling policy). The retailer could also face ...

Outsourcing Through Competition: What Is The Best Competition Parameter?, Ehsan Elahi

Ehsan Elahi

In this paper we consider a single buyer who wants to outsource the manufacturing of a product to N potential suppliers. The buyer’s objective is to maximize the service level she receives from the suppliers. The suppliers compete for the buyer’s demand based on a competition parameter which the buyer announces along with an allocation rule. We model each supplier as a make-to-stock queueing system. Using a simple proportional allocation function, we compare two competition parameters: service level and inventory level. We show that inventory competition creates a higher overall service level for the buyer. We also show ...

Correlation And Regression, Donal O'Brien, Pamela Sharkey Scott

Books/Book Chapters

A correlation is a measure of the linear relationship between two variables. It is used when a
researcher wishes to describe the strength and direction of the relationship between two
normally continuous variables. The statistic obtained is Pearson’s product-moment
correlation (r), and SPSS also provides the statistical significance of r. In addition, if the
researcher needs to explore the relationship between two variables while statistically
controlling for a third variable, partial correlation can be used. This is useful when it is
suspected that the relationship between two variables may be influenced, or confounded, byA correlation is a measure of ...

A Model To Create An Efficient And Equitable Admission Policy For Patients Arriving To The Cardiothoracic Icu, Muer Yang, Michael J. Fry, Corey Scurlock

Operations and Supply Chain Management Faculty Publications

To develop queuing and simulation-based models to understand the relationship between ICU bed availability and operating room schedule to maximize the use of critical care resources and minimize case cancellation while providing equity to patients and surgeons.

Queuing theory and computer simulation can be used to model case flow through a cardiothoracic operating room and ICU. A dynamic admission policy that looks at current waiting time and expected ICU length of stay allows for increased equity between patients with only minimum losses of efficiency. This dynamic admission policy would seem to be a superior in maximizing case-flow. These results may ...

Capacity Planning For Elderly Care In Ireland Using Simluation Modeling, Mohamed Ragab, Waleed Abo-Hamad, Amr Arisha

Conference papers

Global population aging is creating an immense pressure on healthcare facilities making them unable to cope with the growing demand for elderly healthcare services. Current demand-supply gaps result in prolonged waiting times for patients and substantial cost burdens for healthcare systems due to delayed discharges. This paper describes a project aimed at presenting modeling and simulation to address elderly care pathways within the Irish healthcare sector. The management of frail patients admitted to acute hospitals and the introduction of the new intermediate care beds are alternative interventions that healthcare executives are interested in simulating to examine their impact on the ...

"Why Do We Have To Learn This Stuff?" Revising Or Developing A Course Using Essential Questions, Michael E. Cafferky

Faculty Works

This paper explores how the concept of “essential questions” can be used as a structural tool for revising or developing a business course such that active learning and student engagement are fostered. The concept of essential questions is different from and similar to the Socratic method. The relationship between essential questions and other course elements is discussed. An example is provided for how this approach was used in a business ethics course taught from a biblical worldview.

Real Option Management Of Hydrocarbon Cracking Operations, Selvaprabu Nadarajah, Nicola Secomandi, Gary Sowers, John Wassick

Tepper School of Business

Commodity conversion assets play important economic roles. It is well known that the market value of these assets can be maximized by managing them as real options on the prices of their inputs and/or outputs. In particular, when futures on these inputs and outputs are traded, managing such real options, that is, valuing, hedging, and exercising them, is analogous to managing options on such futures, using risk neutral valuation and delta hedging methods. This statement holds because dynamically trading portfolios of these futures and a risk less bond can replicate the cash °ows of these assets. This basic principle ...

The Role Of Price Spreads And Reoptimization In The Real Option Management Of Commodity Storage Assets, Nicola Secomandi

Tepper School of Business

The real option management of commodity storage assets is an important practical problem. Practition- ers approach the resulting stochastic optimization model using heuristic policies that rely on sequential reoptimization of linear programs. Used in conjunction with Monte Carlo simulation, these policies typ- ically yield near optimal lower bound estimates on the value of storage. This paper reveals that a simple one stage lookahead policy is optimal for a fast storage asset without frictions. Thus, in this (not entirely realistic) case the problem is easy and the reoptimization policies are unnecessary, albeit optimal. In contrast, this paper provides numerical and structural ...

Observational Research In A Marketing Classroom: A Guidebook, Kristen Winterton

Undergraduate Honors Theses

Qualitative research plays an integral part in marketing research (Denzin and Lincoln, 1998). In fact, a search of the website for the American Marketing Association for the term “qualitative research” reveals literally hundreds of documents (white papers, case studies, etc) discussing methods of conducting observational research, examples of observational research studies, and the importance of observational research in marketing. Interestingly, though qualitative methods are used frequently by practitioners, they receive very limited attention in marketing textbooks. This seems particularly true of observation research, which is among the least expensive and easily conducted qualitative methods (Mann, 2003). The purpose of this ...

The Problem Of Too Many Statistical Tests: Subgroup Analyses In A Study Comparing The Effectiveness Of Online And Live Lectures, David M. Lane

Numeracy

The more statistical analyses performed in the analysis of research data, the more likely it is that one or more of the conclusions will be in error. Multiple statistical analyses can occur when the sample contains several subgroups and the researchers perform separate analyses for each subgroup. For example, separate analyses may be done for different ethnic groups, different levels of education, and/or for both genders. Media reports of research frequently omit information on the number of subgroup analyses performed thus leaving the reader with insufficient information to assess the validity of the conclusions. This article discusses the problems ...

Financial Services Innovation: Local Strategy, Management, And Change – A Field Investigation, Ann-Catherine Nave

Pursuit - The Journal of Undergraduate Research at the University of Tennessee

This study examines the innovation sources and processes of regional financial services firms through inductive field research. Innovation in these firms, and presumably other financial services firms and other smaller organizations, originate primarily out of three sources, the drive for efficiency, the external environment, and strategic, ambidextrous management. Successfully innovative firms balance the short-term need for efficiency improvements with the long-term desire to grow primarily through visionary, yet adaptive, leadership.

Incomplete Market Models Of Carbon Emissions Markets, Walid Mnif

Electronic Thesis and Dissertation Repository

New regulatory frameworks have been developed with the aim of decreasing global greenhouse gas emissions over both short and long time periods. Incentives must be established to encourage the transition to a clean energy economy. Emissions taxes represent a "price" incentive for this transition, but economists agree this approach is suboptimal. Instead, the "quantity" instrument provided by cap-and-trade markets are superior from an economic point of view. This thesis focuses on the cap-and-trade instrument. Carbon emissions markets have recently been implemented in different countries. We summarize the state of world cap-and-trade schemes. We also provide a literature review of existing ...

Twitter Adoption And Use By Smes: An Empirical Study, S. F. Wamba, Lemuria D. Carter

Dr Samuel Fosso Wamba

Social media tools are used by firms to create and capture business value. In this study, we synthesize emerging literature on social commerce, social media, and the diffusion of innovation to identify the role that organizational, managerial and environmental characteristics of SMEs play in the adoption of Twitter. To test the model, we administered a survey to 453 SME mangers from the United States, the United Kingdom, Australia and India. The results of logistic hierarchical regression indicate that firm innovativeness, age and geographic location have a significant impact on Twitter adoption by SMEs. Implications for research and practice are discussed.
