A fresh look at the contribution of project management to organizational performance

A better understanding of organizational performance and the contribution that project management can make is the aim. The article adopts the “Competing Values Framework,” a rich framework that is well established both theoretically and empirically but is not well known in the field of project management. The framework is summarized and applied in an empirical investigation of the contribution of project management in general and project management offices (PMOs) in particular to organizational performance. The examination of 11 case studies revealed multiple concurrent and sometimes paradoxical perspectives. The criteria proposed by the framework have been further developed through the identification of a preliminary set of empirically grounded performance indicators. The empirical results contribute to a better understanding of the role of project management generally and PMOs specifically. They also demonstrate the usefulness of this framework for the study of project management's contribution to organizational performance.     

Exploring PMOs through community of practice theory

This article explores project management offices (PMOs) through community of practice theory. Preliminary results from a national health care case study are used to confirm the legitimacy of this approach. Today's knowledge‐based economy calls for mechanisms to share knowledge. The issue of making more with less is at stake in order to reuse good practices, support innovative practice, and prevent the reinvention of the wheel. Members of these communities are at the heart of the learning process. The originality of this research is that it sheds light on PMOs in a new theoretical perspective within the field of knowledge management.     

A NOTE ON SEMIPARAMETRIC ESTIMATION OF FINITE MIXTURES OF DISCRETE CHOICE MODELS WITH APPLICATION TO GAME THEORETIC MODELS*

We view a game abstractly as a semiparametric mixture distribution and study the semiparametric efficiency bound of this model. Our results suggest that a key issue for inference is the number of equilibria compared to the number of outcomes. If the number of equilibria is sufficiently large compared to the number of outcomes, root‐n consistent estimation of the model will not be possible. We also provide a simple estimator in the case when the efficiency bound is strictly above zero.     

When innovation in education works: stimulating teachers' innovative work behaviour

The twenty‐first century labour market requires employees that proactively shape innovations and solve complex problems. Professionals in the education sector are expected to perform innovative behaviour that not only entails the generation, but also the realization and sustainable implementation of new ideas. In a sample of 458 employees in Dutch secondary and higher vocational education (abbreviated in Dutch to MBO and HBO, respectively), this study investigated the relation between environmental factors (namely task variety, management support and exposure to innovation) and Innovative Work Behaviour (IWB) across the different phases of the innovation process, including a sustainability phase. Results of hierarchical regression analyses showed that management support and exposure to innovations served as a predictor for all phases of IWB. Teachers with supportive managers and a high degree of exposure to innovations showed higher scores on innovative behaviour across all phases. Linear regressions revealed a significant relationship between task variety and IWB. In the hierarchical model, only management suport and exposure to innovations showed significant relations. Background characteristics, such as gender, age, tenure, number of working hours and type of education, for which we controlled during the analyses, played a role in how much IWB is displayed. It can be concluded that a work environment, in which employees are exposed to innovation and are supported is crucial. Additionally, in view of the role background characteristics play, it is recommended to select teachers with specific profiles for the different phases of the innovation process.     

Creating a Testable, Estimable Model to Inform Our Response to the Test-Score Gap Crisis

The test-score gap between black and white students should be seen as a crisis. We propose a testable model based on readily available data that will allow us to estimate the impact and interrelationships of a multitude of factors that may be partially responsible for the problem. The estimation of this model will require the joint efforts of experts in many areas of education as well as of experts in multilevel structural equation modeling.     

PDE approach to valuation and hedging of credit derivatives

This paper presents a PDE approach in a Markovian setting to hedge defaultable derivatives. The arbitrage price and the hedging strategy for an attainable contingent claim are described in terms of solutions of a pair of coupled PDEs. For some standard examples of defaultable claims, we provide explicit formulae for prices and hedging strategies.     

Human Resources Practices as Predictors of Work-Family Outcomes and Employee Turnover

Drawing on a nonrandom sample of 557 dual-earner white-collar employees, this article explores the relationship between human resources practices and three outcomes of interest to firms and employees: work-family conflict, employees' control over managing work and family demands, and employees' turnover intentions. We analyze three types of human resources practices: work-family policies, human resources incentives designed to induce attachment to the firm, and the design of work. In a series of hierarchical regression equations, we find that work design characteristics explain the most variance in employees' control over managing work and family demands, whereas human resources incentives explain the most variance in work-family conflict and turnover intentions. We also find significant gender differences in each of the three models. Our results suggest that the most effective organizational responses to work-family conflict and to turnover are those that combine work-family policies with other human resources practices, including work redesign and commitment-enhancing incentives.     

Implications of the lome convention for African trade and development

Conclusion The analysis presented here does not support the contention that the Lomé Convention is a turning point in the history of relations between rich and poor nations, and the herald of a new economic order, more just and equitable. While Lomé does not represent radical departures from the present system, it reflects the realization by the vulnerable, resource-poor EEC that some concessions had to be made in the fields of trade and aid. The reforms include: greater trade preferences; STABEX; some participation in the decision-making process of the EDF; financing of economic integration among the ACPs. These modifications, however, do not repudiate the present system, but rather make it more viable. The power of the multinationals is in no way affected, and the pattern of unequal development is left intact. Lomé-type relationships between the poor and rich countries will at best provide the elites with increased resources which might lead to national capitalist development, strengthening of the elites’ material base, and reproduction of the structure of dependence and inequality.     

Estimation of Poverty Transition Matrices with Noisy Data

This paper investigates measurement error biases in estimated poverty transition matrices. We compare transition matrices based on survey expenditure data to transition matrices based on measurement‐error‐free simulated expenditure. The simulation model uses estimates that correct for measurement error in expenditure. We find that time‐varying measurement error in expenditure data magnifies economic mobility. Roughly 45% of households initially in poverty at time t ? 1 are found to be out of poverty at time t using data from the Korean Labor and Income Panel Study. When measurement error is removed, this drops to between 26 and 31% of households initially in poverty. Copyright © 2016 John Wiley & Sons, Ltd.
