Real Wages And Labour Productivity In Tanzania: How Do They Link?, Abel A. Kinyondo, Rizwanul Islam, Joseph Nganga 2015 University of Dar Es Salaam

Real Wages And Labour Productivity In Tanzania: How Do They Link?, Abel A. Kinyondo, Rizwanul Islam, Joseph Nganga

Abel A Kinyondo

Using data from national level surveys, the present paper undertakes an empirical analysis of the linkage between labour productivity and real wages in Tanzania. After making tabular presentations of growth in labour productivity and real wages by industry and sector (public and private), regression analysis is undertaken to examine the factors that influence incomes. Granger causality test is applied to explain the nature of the relationship between rel wages and productivity for manufacturing industries. The paper finds no clear pattern in link between real wages and productivity. Real incomes in the private sector have registered negative growth while the opposite ...


An Analytical Representation Of Flexible Resource Allocation In Hospitals, Michael Thorwarth, Wael Rashwan, Amr Arisha 2015 Dublin Institute of Technology

An Analytical Representation Of Flexible Resource Allocation In Hospitals, Michael Thorwarth, Wael Rashwan, Amr Arisha

Articles

Non-linear processes within complex systems are difficult to predict. Using discrete event simulation (DES) models can be helpful for presenting the uncertainty level embedded within these processes. However, the interpretations of the resulting outcomes can be challenging to analyze. This is evident when experimenting with simulation models, and therefore requires the adaptation of existing models. Introducing cyclic entities such as interconnected resources to the simulation model adds a new level of complexity to the model. In practical cases, decision makers often demand a model that enables them to make quick decisions with less complexity involved. However, these individuals still want ...

Do Competing Suppliers Maximize Profits As Theory Suggests? An Empirical Evaluation, Ehsan Elahi, Roger Blake 2015 UMASS Boston

Do Competing Suppliers Maximize Profits As Theory Suggests? An Empirical Evaluation, Ehsan Elahi, Roger Blake

Ehsan Elahi

This research compares results from laboratory experiments with predictions from theory for decisions made by competing suppliers. We consider a supply chain in which a single buyer outsources the manufacture of a commodity product to suppliers not on the basis of price, but rather on service. Three different criteria on which suppliers compete are evaluated: 1) a guaranteed specific inventory fill-rate, 2) guaranteed level of base-stock, and 3) a parameter optimizing the supply chain in the buyer’s favor. Our results show that in most cases, suppliers’ decisions are significantly different than the Nash equilibrium, meaning that they do not ...


Project Management Decisions With Uncertain Targets, Jeffrey Keisler, Robert Bordley 2015 University of Massachusetts Boston

Project Management Decisions With Uncertain Targets, Jeffrey Keisler, Robert Bordley

Jeffrey Keisler

Project management decision rules presume that fixed and inflexible targets have been defined for the project. If a project's slack is defined as the difference between actual project performance and these targets, then these decision rules can be characterized as maximizing the probability that slack is non-negative (i.e., maximizing the probability of meeting the targets). These rules rely on z-scores to compare uncertain performance to target levels. Following these decision rules will not always suffice for the project manager to act consistently with customer preferences. In particular, actual requirements may be uncertain or subject to change, and customers ...

Applying The Analytic Hierarchy Process To Oil Sands Environmental Compliance Risk Management, Izak Johannes Roux

Dissertations and Doctoral Studies

Oil companies in Alberta, Canada, invested $32 billion on new oil sands projects in 2013. Despite the size of this investment, there is a demonstrable deficiency in the uniformity and understanding of environmental legislation requirements that manifest into increased project compliance risks. This descriptive study developed 2 prioritized lists of environmental regulatory compliance risks and mitigation strategies and used multi-criteria decision theory for its theoretical framework. Information from compiled lists of environmental compliance risks and mitigation strategies was used to generate a specialized pairwise survey, which was piloted by 5 subject matter experts (SMEs). The survey was validated by a ...

Human Factors Analysis And Classification System Interrater Reliability For Biopharmaceutical Manufacturing Investigations, Roberto Cintron 2015 Walden University

Human Factors Analysis And Classification System Interrater Reliability For Biopharmaceutical Manufacturing Investigations, Roberto Cintron

Dissertations and Doctoral Studies

Human errors are an expected result of operations performed by individuals and frequently lead to accidents and other catastrophic events. The problem is that the current process used to investigate and mitigate human errors in the biopharmaceutical manufacturing industries is not effective, as it does not include the effects of human factors found to be effective in aviation and nuclear power organizations. The human factors and classification system (HFACS) was created for the investigations of accidents using the Swiss cheese model of accident causation as a theoretical framework. The purpose of this quantitative, inter-rater reliability study was to demonstrate the ...

Exploring Government Contractor Experiences Assessing And Reporting Software Development Status, Putnam P. Texel 2015 Walden University

Exploring Government Contractor Experiences Assessing And Reporting Software Development Status, Putnam P. Texel

Dissertations and Doctoral Studies

Reports from academic, commercial, and government organizations have documented software-intensive system cost and schedule overruns for decades. These reports have identified lack of management insight into the software development process as one of many contributing factors. Multiple management mechanisms exist. However, these mechanisms do not support the assessment, and subsequent reporting, of software completion status. Additionally, the conceptual framework, based on industry standards, is limited in its relevance to this study due to an emphasis on what is needed while deferring implementation details. The purpose of this phenomenological study was to explore U.S. government contractors' lived experiences of assessing ...

The Influence Of Mindfulness During The Travel Anticipation Phase On Search And Choice Behaviors, Search And Choice Outcomes, And Trip Evaluations, Lorraine Taylor

All Dissertations

Anticipation is the first travel phase (Clawson & Knetsch, 1966) and consists of the vacation planning process. Tourists may exhibit varying levels of mindfulness during this phase. Mindfulness is associated with analytic decision making through a heightened sensitivity to one's environment and openness to new information (Langer & Moldoveanu, 2000). This study considered the influence that mindfulness during the travel anticipation phase has on: search and choice behaviors, search and choice outcomes, and trip evaluations. Analysis was also conducted to determine if there was a significant influence on the relationships based on the mediating effect of the amount of the trip ...

Assessing Student Leadership Competencies And Adequacy Of Preparation In Seminary Training, Valerie Miles-Tribble 2015 Walden University

Assessing Student Leadership Competencies And Adequacy Of Preparation In Seminary Training, Valerie Miles-Tribble

Dissertations and Doctoral Studies

As more seminary student-practitioners seek non-pastoral leadership roles in faith-based

and secular organizations, the complexities of the roles demand leadership competencies beyond traditional religious study. Limited research assessing leadership competencies in seminary contexts raises uncertainty about whether leadership preparation needs are addressed adequately in seminary. This quantitative study focused on whether or not student self-assessed adequacy of preparation is related to, affected by, or influenced by self-assessed leadership competencies, individually or in the aggregate. The theoretical foundation joined Evers, Rush, and Berdrow's learner-centered theory that urges student input on competency development needs and Boyatzis's leadership competency theory that ...
