The problem addressed in this study is that little action is taken to create the social aspects and social value of knowledge-sharing culture within organizations. There is a need for increased understanding of the behavioral side of knowledge management. The purpose of this study was to focus on knowledge sharing from a behavioral perspective. Knowledge management is defined as the accumulation, protection, and leverage of knowledge. This research study investigated the relationship between knowledge sharing and competitiveness and approached the field of knowledge management from the organizational, cultural, and behavioral perspectives. The research questions examined how knowledge workers described the ...


Improving The Detection Of Narcissistic Transformational Leaders With The Multifactor Leadership Questionnaire: An Item Response Theory Analysis, Dale Frederick Hosking Martin 2011 Walden University

Improving The Detection Of Narcissistic Transformational Leaders With The Multifactor Leadership Questionnaire: An Item Response Theory Analysis, Dale Frederick Hosking Martin

Walden Dissertations and Doctoral Studies

Narcissistic transformation leaders have inflicted severe physical, psychological, and financial damage on individuals, institutions, and society. Multifactor Leadership Questionnaire (MLQ) has shown promise for early detection of narcissistic leadership tendencies, but selection criteria have not been established. The purpose of this quantitative research was to determine if item response theory (IRT) could advance the detection of narcissistic leadership tendencies using an item-level analysis of the 20 transformational leadership items of the MLQ. Three archival samples of subordinates from Israeli corporate and athletic organizations were combined (N = 1,703) to assess IRT data assumptions, comparative fit of competing IRT models, item ...


Examining Perceptions Of Managers And Financial Advisors Of A Mentoring Program On Productivity And Retention, Marston A. Thomas 2011 Walden University

Examining Perceptions Of Managers And Financial Advisors Of A Mentoring Program On Productivity And Retention, Marston A. Thomas

Walden Dissertations and Doctoral Studies

Researchers have found that 90% of financial advisors leave the life insurance industry in first year, 68% in the second year, and 50% in the third year. Researchers have noted the importance of mentorship aimed at work attitudes, yet there is a lack of research concerning attrition and its effects on the industry. The purpose of this quantitative study was to examine managers' and financial advisors' perception of a mentoring program on advisors productivity and retention. Social learning theory was applied as the theoretical framework for this study. Data were collected from financial advisors and their managers across 13 branch ...

The problem addressed in this research was non acceptance of simulation technology by project managers. This research investigated the correlation among personal innovativeness, organizational innovativeness, perceived usefulness, perceived ease ...


Identification Of Patterns In Genetic-Algorithm-Based Solutions For Optimization Of Process-Planning Problems Using A Data Mining Tool, Dowluru Sreeramulu 2011 Walden University

Identification Of Patterns In Genetic-Algorithm-Based Solutions For Optimization Of Process-Planning Problems Using A Data Mining Tool, Dowluru Sreeramulu

International Journal of Applied Management and Technology

This paper presents a novel use of data mining algorithms for extraction of knowledge from a set of process plans. The purpose of this paper is to apply data mining methodologies to explore the patterns in data generated by genetic-algorithm-generating process plans and to develop a rule set planner, which helps to make decisions in odd circumstances. Genetic algorithms are random-search algorithms based on the mechanics of genetics and natural selection. Because of genetic inheritance, the characteristics of the survivors after several generations should be similar. The solutions of a genetic algorithms for process planning consists of the operation sequence ...


Rejoinder: Estimation Issues For Copulas Applied To Marketing Data, Peter Danaher, Michael Smith 2010 Melbourne Business School

Rejoinder: Estimation Issues For Copulas Applied To Marketing Data, Peter Danaher, Michael Smith

Michael Stanley Smith

Estimating copula models using Bayesian methods presents some subtle challenges, ranging from specification of the prior to computational tractability. There is also some debate about what is the most appropriate copula to employ from those available. We address these issues here and conclude by discussing further applications of copula models in marketing.


Forecasting Television Ratings, Peter Danaher, Tracey Dagger, Michael Smith 2010 Monash University

Forecasting Television Ratings, Peter Danaher, Tracey Dagger, Michael Smith

Michael Stanley Smith

Despite the state of flux in media today, television remains the dominant player globally for advertising spend. Since television advertising time is purchased on the basis of projected future ratings, and ad costs have skyrocketed, there is increasing pressure to forecast television ratings accurately. Previous forecasting methods are not generally very reliable and many have not been validated, but more distressingly, none have been tested in today’s multichannel environment. In this study we compare 8 different forecasting models, ranging from a naïve empirical method to a state-of-the-art Bayesian model-averaging method. Our data come from a recent time period, 2004-2008 ...

Improving Hurricane Disaster Preparedness: Models For Optimal Reallocation Of Hospital Capacity, Jomon Paul, Rajan Batta 2010 Kennesaw State University

Improving Hurricane Disaster Preparedness: Models For Optimal Reallocation Of Hospital Capacity, Jomon Paul, Rajan Batta

Jomon Aliyas Paul

This research presents significant improvements to the hospital capacity planning models for hurricane disaster proposed by Paul and Batta. Firstly, we develop a model that reallocates hospital capacities taking into account the effect of casualty severity on medical care demands and travel time to hospitals on casualty outcomes. Secondly, travel time to hospitals, a key input to the model, is estimated using a stochastic simulation. Thirdly, in order to meet with challenges that arise as disaster evolves, we develop an algorithm that dynamically updates the pre-disaster plans to post-disaster reality. The algorithm evaluates prior decisions by dynamically updating the hospital ...


An Invitation To Portfolio Decision Analysis, Ahti Salo, Jeffrey Keisler, Alec Morton 2010 Aalto University

An Invitation To Portfolio Decision Analysis, Ahti Salo, Jeffrey Keisler, Alec Morton

Jeffrey Keisler

Portfolio Decision Analysis (PDA) – the application of decision analysis to the problem of selecting a subset or portfolio from a large set of alternatives – accounts for a significant share, perhaps the greater part, of decision analysis consulting. By construction, PDA has a sound theoretical and methodological basis, and its ability to contribute to better resource allocation decisions has been demonstrated in numerous applications. This book pulls together some of the rich and diverse efforts as a starting point for treating PDA as a promising and distinct area of study and application. In this introductory chapter, we first describe what we ...

Modelling The Impact Of Personality On Individual Performance Behavior With A Time-Varying Mixture Of Monotonic Random Effects, Sally A. Wood, Edward J. Cripps, Robert E. Wood, John Lau 2010 University of Western Australia

Modelling The Impact Of Personality On Individual Performance Behavior With A Time-Varying Mixture Of Monotonic Random Effects, Sally A. Wood, Edward J. Cripps, Robert E. Wood, John Lau

Sally Wood

A method is presented for flexibly modelling longitudinal data that provides insight to a central question in psychology theory: the dependency between personality clas- sification and individual performance behavior. Flexibility is achieved by assuming the regression coefficients of random effects models are generated from a time-varying mixture of an unknown but finite number of processes, where the weights attached to the number of processes are parameterised to depend upon an individual’s personality classification. For a given number of mixture components the component processes are constrained distributions and the weights attached to them depend upon time. The method is made ...


A Semantic Analysis Approach For Assessing Professionalism Using Free-Form Text Entered Online, Roger H. Blake 2010 University of Massachusetts - Boston

A Semantic Analysis Approach For Assessing Professionalism Using Free-Form Text Entered Online, Roger H. Blake

Roger H. Blake

This paper presents the results of an experimental study to measure professionalism for the purpose of assessing a professional development program. Soft skills such as professionalism are increasingly recognized as important, yet measuring and assessing these skills, typically best acquired experientially, has remained challenging. Following established research, we conceptualize professionalism as a construct with the dimensions of autonomy, commitment, belief in public service, self-regulation, and the use of a professional organization as a major referent. We demonstrate how these dimensions can be expressed and the professionalism of free-form text responses measured. These responses are reflections submitted online by participants in ...

Uncovering Europe’S Best Goalscorers From The 2009-2010 Season, Joel Oberstone 2010 University of San Francisco

Uncovering Europe’S Best Goalscorers From The 2009-2010 Season, Joel Oberstone

Joel Oberstone

The search for great goalscorers in football has been traditionally tunnel-visioned. Prestigious individual football awards, such as the Golden Boot and the Ballon d’Or, are almost automatically given to the player with the highest goal count. Simple. Nothing usually complicated about this selection process. Except, this one-dimensional approach may be missing some less-then-obvious gems of goalscoring by not considering the overall contributions a player makes to his team’s offensive performance as indicated by more subtle measures.

The contributions made during the 2009-2010 season by the 20 leading goal scorers from each of the six most prestigious football leagues ...

This is an example Windows 32bit program to estimate a Gaussian copula model with NBD margins. The margins are estimated first using MLE, and the copula second using Bayesian MCMC. The model was discussed in Danaher & Smith (2011; Marketing Science) as example 4 (section 4.2).


Modeling Multivariate Distributions Using Copulas: Applications In Marketing, Peter J. Danaher, Michael S. Smith 2010 Melbourne Business School

Modeling Multivariate Distributions Using Copulas: Applications In Marketing, Peter J. Danaher, Michael S. Smith

Michael Stanley Smith

In this research we introduce a new class of multivariate probability models to the marketing literature. Known as “copula models”, they have a number of attractive features. First, they permit the combination of any univariate marginal distributions that need not come from the same distributional family. Second, a particular class of copula models, called “elliptical copula”, have the property that they increase in complexity at a much slower rate than existing multivariate probability models as the number of dimensions increase. Third, they are very general, encompassing a number of existing multivariate models, and provide a framework for generating many more ...

Bicycle Commuting In Melbourne During The 2000s Energy Crisis: A Semiparametric Analysis Of Intraday Volumes, Michael S. Smith, Goeran Kauermann

Michael Stanley Smith

Cycling is attracting renewed attention as a mode of transport in western urban environments, yet the determinants of usage are poorly understood. In this paper we investigate some of these using intraday bicycle volumes collected via induction loops located at ten bike paths in the city of Melbourne, Australia, between December 2005 and June 2008. The data are hourly counts at each location, with temporal and spatial disaggregation allowing for the impact of meteorology to be measured accurately for the first time. Moreover, during this period petrol prices varied dramatically and the data also provide a unique opportunity to assess ...


The Best Selection Of Strategic Plans In Balanced Scorecard Using Multi-Objective Decision Making Model, J Dodangeh 2010 Selected Works

The Best Selection Of Strategic Plans In Balanced Scorecard Using Multi-Objective Decision Making Model, J Dodangeh

Jay Daniel

In an increasingly competitive business environment, many organizations have adopted the strategic planning approach in an attempt to achieve excellence in business. Implementation of appropriate strategies plays an important role for organizations' success. Balanced scorecard is an appropriate tool used for designing operational strategies. However, one of the balanced scorecard problems is its selection in strategic plans' performance. In this paper, a model was established for the selection of strategic plans in “balanced scorecard” using “goal programming model” which is one of the multi objective decision making models. So, using the consensus of organizations’ managers and experts' opinions, the measures ...
