Fisheries Occasional Paper No. 14 - Department Of Fisheries Stakeholder Survey 2004, Tara Baharthah

Fisheries Occasional Publications

A telephone survey of Department of Fisheries' stakeholders was conducted in August 2004 in order to evaluate their perception of the Department's management of commercial and recreational fishing, pearling and aquaculture, and fish and fish habitat protection. The survey also assessed satisfaction with the level of service provided to stakeholders and their involvement in decision making processes.

The results of this survey were compared to a similar survey conducted during 2002 and a survey of the general public conducted during 2004.

The sample comprised of 145 interviews - 41 representing the commercial fishing sector, 40 representing the recreational fishing sector, …

Obesity, Educational Attainment, And State Economic Welfare, Martin W. Sivula Ph.D.

MBA Faculty Conference Papers & Journal Articles

For the first time in history, estimates of the overweight people in the world rival estimates of those malnourished. The World Health Organization (WHO, 2002) ranked obesity among the top 10 risks to human health worldwide. In the early 1960s, nearly half of the Americans were overweight and 13% were obese. Today some 64% of U.S. adults are overweight and 30.5% are obese. Even more alarming, twice as many U.S. children are overweight than were twenty years ago, a 66% increase. Non-communicable diseases impose a heavy economic burden on already strained health systems. Health is a key determinant of development …

Reinventing Leadership: Blended Dualism, Andrew Sikula Sr., Chong W. Kim

Management Faculty Research

Leadership needs to be redefined and explained differently in terms of what we have learned about organizational directorship during the last few decades. In addition to a new definition, a post twentieth century model of leadership needs created with steps and parameters opposite from pre-2000 thinking and philosophy. This article presents a new leadership definition and model, plus it identifies leadership parameters, steps, and lessons. Furthermore, it introduces a new concept into management/leadership/organization literature called Blended Dualism which incorporates the very latest supervisory thinking into a holistic, integrated amalgam of what initially appears to be contradictory or at least paradoxical …

A Comparative Study Of Parametric And Nonparametric Estimators Of Old-Age Mortality In Sweden, Peter Fledelius, Montserrat Guillen, Jens Perch Nielsen, Kitt Skovso Petersen

Journal of Actuarial Practice (1993–2006)

A recent study of Swedish old-age mortality used a modified GompertzMakeham model with a linear hazard for the force of mortality. We propose an alternative model using smooth two-dimensional kernel hazard estimators and introduce a new estimator based on the multiplicative bias correction for the multivariate marker dependent hazard. The multiplicative bias correction appears to have great potential for estimating mortality rates at the highest ages. We also observe that mortality continues to increase at an exponential rate even in old-age.

Phased Retirement For Defined Benefit Plan Participants, Patricia L. Scahill, Jonathan Barry Forman

Journal of Actuarial Practice (1993–2006)

The demographic makeup of the U.S. workforce is changing. The population between ages SS and 64 is projected to increase significantly by 2020, but employment rates for this age group have not been increasing. Employers will likely need to encourage critical employees in this age group to delay retirement. Phased retirement is one tool for delaying retirement, while also not continuing full-time employment, so it can be a compromise for employers and employees. Both Congress and two administrative agencies have begun to consider changes in pension laws and regulations that would be needed to accommodate phased retirement for employers who …

Credibility Theory And Geometry, Elias S.W. Shiu, Fuk Yum Sing

Journal of Actuarial Practice (1993–2006)

We present a geometric approach to studying greatest accuracy credibility theory. Our main tool is the concept of orthogonal projections. We show, for example, that to determine the Buhlmann credibility premium is to find the coefficients of the minimum-norm vector in an affine space spanned by certain orthogonal random variables. Our approach is illustrated by deriving various common credibility formulas. Several equivalent forms of the credibility factor Z are derived by means of similar triangles.

Estimation Of Complete Period Life Tables For Singaporeans, Siu-Hang Li, Wai-Sum Chan

Journal of Actuarial Practice (1993–2006)

Complete period life tables, with death rates for every year of age, are not available in Singapore. This study constructs such tables for Singaporeans from the limited mortality information contained in the abridged life tables provided by the Singapore Department of Statistics. We find that linear interpolation, Whittaker graduation, and the Coale-Kisker method together can generate complete life tables that are smooth and continuous. The validity of the complete life tables generated by our method is further confirmed by (1) comparing the life expectancies calculated from our estimated life tables with those provided by the Singapore Department of Statistics, and …

Does Baldrige Make A Business Case For Quality?, Mark L. Dean, Cynthia L. Tomovic

STEMPS Faculty Publications

The Malcolm Baldrige National Quality Award (MBNQA) is a widely accepted model promoting quality management as a means to business success. However, because business results are themselves part of the model, the contribution of the approach-deployment elements to results cannot be determined. The National Institute of Standards and Technology (NIST) maintains a history of Baldrige applications and the results of their evaluations. Statistical analysis of these data could yield insight into whether the approach-deployment advocated by the Baldrige model actually produces excellent results. Although NIST does not currently allow access to the data, future empirical evaluation of the data could …

The Actuarial Value Of Life Insurance Backdating, James M. Carson, Krzysztof Ostaszewski

Journal of Actuarial Practice (1993–2006)

Backdating is a common (and legal) practice in the U.S. whereby a life insurance contract bears a policy date that is prior to the actual application date. This practice often results in the opportunity for some insureds to reduce the annual premium paid. Using cash flow projections and U.S. mortality, lapse, and interest rate data, we provide a model of the actuarial value of term life insurance backdating. Results indicate that the benefits to the applicant of backdating a term life insurance policy increase as the applicant age (and hence premium) increases. Increasing mortality, lapse, and interest rates, as well …

Decision Tree Analysis Of Terminated Life Insurance Policies, Robert Keng Heong Lian, Yuan Wu, Hian Chye Koh

Journal of Actuarial Practice (1993–2006)

Statistical methods such as regression and survival analysis have traditionally been used to investigate the factors affecting the duration of terminated life insurance policies. This study explores a different approach: it uses a more recently developed data mining technique called decision trees. By sequentially partitioning the data to maximize differences in the dependent variable (duration in this study), the decision trees technique is good at identifying data segments with significant differences in the dependent variable. This identification can be useful when a company is trying to understand the factors driving or associated with the termination of life insurance policies. Decision …

Rapid Calculation Of The Price Of Guaranteed Minimum Death Benefit Ratchet Options Embedded In Annuities, Eric R. Ulm

Journal of Actuarial Practice (1993–2006)

This paper presents a new method of obtaining quick and accurate values and deltas for discrete look back options using Taylor series expansions. This method is applied to the case of ratchet guaranteed minimum death benefits attached to annuity contracts, and the method is extended to include annuities where a fixed fund is attached to the variable account. Finally, both the speed and the accuracy of the method are compared to Monte Carlo simulation and the exact analytic solution. The Taylor expansion method is shown to be faster and, in most cases, more accurate than the alternative methods.

Approximating The Bias And Variance Of Chain Ladder Estimates Under A Compound Poisson Model, Janagan Yogaranpan, Sue Clarke, Shauna Ferris, John Pollard

Journal of Actuarial Practice (1993–2006)

We consider the problem of estimating the outstanding claims produced by a homogeneous general insurance portfolio. The specific model considered in this paper is one where the number of claims in any loss period follows a Poisson distribution, settlement delays follow the same multinomial distribution, and settlements are single lump sums that are independent identically distributed random variables. Simulations using this model reveal that the development ratios and the outstanding claims estimates produced using the chain ladder method are positively biased. We obtain approximate formulas for the biases using Taylor series expansions of the random variables about their means. The …

Product Innovation In Financial Services: A Survey, Christopher O'Brien

Journal of Actuarial Practice (1993–2006)

This paper considers product innovation in insurance and other financial services, an area where actuaries have an important role. It considers the proposition that there is no unique formula for success and that what works well in one situation may not work well in another. It first examines the sources of ideas for new products and, in particular, the role played by consumers, which is generally regarded as weak. It then looks at how ideas are implemented, with particular importance attributed to cross-functional teams and the formality of the product development process. Then it considers how success is measured (with …

Positive Psychological Capital: Beyond Human And Social Capital, Fred Luthans, Kyle W. Luthans, Brett C. Luthans

Department of Management: Faculty Publications

With the rising recognition of human resources as a competitive advantage in today’s global economy, human capital and, more recently, social capital are being touted in both theory, research, and practice. To date, however, positive psychological capital has been virtually ignored by both business academics and practitioners. “Who I am” is every bit as important as “what I know” and “who I know.” By eschewing a preoccupation with personal shortcomings and dysfunctions and focusing instead on personal strengths and good qualities, today’s leaders and their associates can develop confidence, hope, optimism, and resilience, thereby improving both individual and organizational performance.

Human, Social, And Now Positive Psychological Capital Management: Investing In People For Competitive Advantage, Fred Luthans, Carolyn M. Youssef

Department of Management: Faculty Publications

There is growing evidence that human resources are crucial to organizational success, and may offer the best return on investment for sustainable competitive advantage. Jeffery Pfeffer’s extensive work, summarized in his book The Human Equation, discusses substantially supported but unfortunate findings that only about half of today’s organizations and their managers believe that human resources really do matter. Moreover, only half of those organizations act upon their beliefs beyond paying lip service to this vital resource. Few organizations have adopted high performance work practices, such as 360-degree feedback, pay-for-performance, self-managed teams, employee empowerment, and other human-oriented initiatives. Furthermore, Pfeffer shows …

Recognition And Development Of Hope For South African Organizational Leaders, Fred Luthans, René Van Wyk, Fred Walumbwa

Department of Management: Faculty Publications

The significant challenges faced by South Africa at present are well known. How to deal with the problems from a political and economic perspective abound, but taking a psychological approach has been neglected. This paper proposes a positive approach to South African organizational leadership based on the psychological capacity of hope. After giving a brief background on the context surrounding South African organizations, the theory, research, and application of hope relevant to organizational leadership in the “Rainbow Nation” are presented and analyzed. Such an overlooked positive approach represented by hopeful organizational leaders seems needed at this juncture of South Africa’s …

Unlocking The Mask: A Look At The Process By Which Authentic Leaders Impact Follower Attitudes And Behaviors, Bruce Avolio, William L. Gardner, Fred Walumbwa, Fred Luthans, Douglas R. May

Department of Management: Faculty Publications

The conceptual and empirical links between authentic leadership and follower attitudes, behaviors, and performance outcomes have not been fully developed. Although we have a number of articles developing the theory of authentic leadership and testing propositions that will appear in a forthcoming special issue of The Leadership Quarterly (Vol. 16, Issue 3, 2005), the focus of this article is to provide some of the initial foundation work for the broader theoretical framework of how authentic leaders influence follower attitudes, behaviors, and performance. Here, we draw from positive organizational behavior, trust, hope, emotion, identification, and identity theories to describe the processes …

It Competency And Firm Performance: Is Organizational Learning A Missing Link?, Michael J. Tippins, Ravipreet S. Sohi

Department of Marketing: Faculty Publications

Many companies have developed strategies that include investing heavily in information technology (IT) in order to enhance their performance. Yet, this investment pays off for some companies but not others. This study proposes that organization teaming plays a significant role in determining the outcomes of IT. Drawing from resource theory and IT literature, the authors develop the concept of IT competency. Using structural equations modeling with data collected from managers in 271 manufacturing firms, they show that organizational learning plays a significant role in mediating the effects of IT competency on firm performance.

Fisheries Occasional Publication No. 8 - Department Of Fisheries Stakeholder Survey 2002, Tara Baharthah, Neil R. Sumner

A telephone survey of Department of Fisheries' stakeholders was conducted in November 2002 in order to evaluate their perception of the Department's management of commercial and recreational fishing, pearling and aquaculture, and fish and fish habitat protection. The survey also assessed satisfaction with the level of service provided to stakeholders and their involvement in the decision making process.

The sample comprised of 149 interviews - 40 representing the commercial fishing sector, 40 representing the recreational fishing sector, 40 representing fish and fish habitat protection, and 29 representing aquaculture and pearling.

In general, the stakeholders gave positive responses regarding the Department …

Recognizing Macroeconomic Fluctuations In Value Based Management, Lars Oxelheim, Clas Wihlborg

Business Faculty Articles and Research

Value Based Management (VBM) has become a common tool for evaluating corporate strategies and projects from the perspective of shareholder value maximization, and can be an important input for corporate compensation systems. But traditional VBM frameworks make no systematic effort to distinguish between changes in performance attributable to macroeconomic fluctuations beyond management's control and changes in performance that reflect the intrinsic competitive position of the firm.

The authors have developed an approach for “filtering out” the impact of macroeconomic fluctuations on cash flows for purposes of performance evaluation. Such fluctuations are captured by changes in exchange rates, interest rates, and …

Behavioral Management And Task Performance In Organizations: Conceptual Background, Meta-Analysis, And Test Of Alternative Models, Alexander D. Stajkovic, Fred Luthans

Department of Management: Faculty Publications

In this study, we provide the conceptual background, meta-analyze available behavioral management studies (N = 72) in organizational settings, and examine whether combined reinforcement effects on task performance are additive (sum of individual effects), redundant (combined effects are less than the additive effects), or synergistic (combined effects are greater than the sum of the individual effects). We found a significant overall average effect size of (d.) = .47 (16% improvement in performance; 63% probability of success), and a significant within-group heterogeneity of effect sizes. To account for this variation, we conducted a theory-driven moderator analysis, which indicated that money, feedback, …

360-Degree Feedback With Systematic Coaching: Empirical Analysis Suggests A Winning Combination, Fred Luthans, Suzanne J. Peterson

Department of Management: Faculty Publications

Wanted: High-performance work practices to gain a competitive advantage. An increasingly common answer to this desperate call is 360-degree programs; unfortunately, they have, at best, mixed reviews when empirically assessed. This study found that a way to improve the effectiveness of 360s may be to combine them with coaching focused on enhanced self-awareness and behavioral management. In a small manufacturer, this feedback-coaching resulted in improved manager and employee satisfaction, commitment, intentions to turnover, and at least indirectly, this firm’s performance. This feedback-coaching may be a winning combination to help in the competitive battles in today’s global economy.

What Knowledge Managers Really Do: An Empirical And Comparative Analysis, Arben Asllani, Fred Luthans

Department of Management: Faculty Publications

The advent of information technology has generated not only interest in how to acquire, store and ‘‘mine’’ data, but also how to manage knowledge. Yet, there is still considerable confusion and a lack of understanding of what today’s knowledge managers really do. Continuing a stream of previous research on the behavior activities of traditional managers, this study investigated the relative amount of time today’s knowledge managers (N = 307) spend on traditional management functions, communications, human resources and networking. Besides identifying what knowledge managers really do, this study examined what successful knowledge managers do. Comparisons are then made with …

Sampling Concepts, Paul Boyd, Ph.D.

MBA Faculty Conference Papers & Journal Articles

The usefulness of any research is dependent upon how well the group studied represents the group about which decisions are to be made or conclusions drawn. That is, it depends upon how well the sample reflects relevant characteristics of the population. When it is possible to study every member of that group there is no problem, for on these occasions we can easily calculate the exact attribute (parameter) of interest for our population.

For example, if we were interested in determining the average number of gallons of gasoline sold to customers at our service station yesterday, we …
