Research on projects is not only an immature field of research, but it is also insubstantial when it comes to understanding what occurs in projects. This article contributes to making project management research matter to the academic as well as to the practitioner by developing a project‐as‐practice approach, in alignment with the ongoing debate in social science research. The article outlines a framework and argues that there are two major challenges to the researcher and also suggests how these challenges can be met. Underlying notions of the practice approach are outlined to ensure a development of the project‐as‐practice approach that makes project management research matter!  相似文献

We investigate if the association between family background and income in Sweden has changed for men born between 1932 and 1968. Our main finding is that the share of the variance in long-run income that is attributable to family background, the so-called brother correlation in income, has fallen by some 17% from 0.49 for the cohorts of brothers born in the early 1930s to below 0.32 for the cohorts born around 1950. From then on, the correlations have inched back up to around 0.37. We report suggestive evidence that the decline is driven by changes in education.  相似文献

This paper presents modeling approaches for wildlife and species conservation with a special emphasis on large mammals in a developing country setting. In such countries there are frequently conflicts over land use and species conservation, and institutions for managing conflicts are often weak or even lacking. In addition, most of the world species and biodiversity are found in developing countries. Two main issues are discussed. First, we study a situation where the wildlife is valuable, but is considered a pest by the local people living close to the wildlife. Second, we consider models with a discrepancy between management geography and biological geography, and where the species flows between a conservation area with no harvesting and a neighboring area with harvesting and possible habitat degradation.  相似文献

The forward-looking linear quadratic adjustment cost (LQAC) model has received attention when modelling prices. Empirical evidence supporting the model seems, however, ambiguous. We find that the LQAC-model is severely at odds with price data for Norwegian machinery exports also when the pure forward-looking rule is augmented by additional lags of the targeted variable. A conditional equilibrium correction (EqCM) model explains the export price behaviour more accurately. Our findings may rule out a large class of expectations based models and not just the particular LQAC-model in the formation of export prices. We also demonstrate that the EqCM-model performs well post-sample despite that monetary policy in Norway has changed from a fixed to a floating exchange rate regime following a recent introduction of inflation targeting. This regime robustness shows that the Lucas critique lacks force empirically in our case.  相似文献

This study develops a model for wildlifemigrating seasonally between a conservationarea and a neighbouring area. When beingoutside the conservation area, harvesting takesplace by a group of small-scale farmers. Thelocal people have two motives for harvesting;to get rid of ``problem' animals as roamingwildlife destroys crops and agriculturalproducts, and hunting for meat and trophies.Depending on the specification of the propertyrights, the harvesting is legal or illegal. Itis demonstrated that it is far from clear whichof the two property rights regimes that givesthe highest wildlife abundance. Hence, contraryto what is argued for in the literature,handing the property rights over to the localpeople means not automatically more wildlifeand a more ``sustainable' resource utilization.The reason lies in the nuisance motive forharvesting. The exploitation under the twodifferent property rights regimes areillustrated by numerical calculations with datathat fits reasonable well with the exploitationof the wildebeest population in theSerengeti-Mara ecosystem.  相似文献

This study presents a multidimensional taxonomy of “ecopreneurship” for small manufacturing firms. Based on a cluster analysis of 312 Swedish firms, four distinct clusters are identified: pioneers, green dumpers, overlookers, and recyclers. These clusters are compared regarding their level of entrepreneurial orientation and firm performance. Based on the results, and because of the resource constraints associated with small firms, managers of such companies are advised to examine the economic consequences of specific environmental business practices and to adopt a less aggregated approach to ecopreneurship. This study illustrates the usefulness of a multidimensional scale when researching environmental behaviors and is a response to the lack of an empirically based classification of ecopreneurship configurations.  相似文献

This paper examines from a technology management perspective the prospects for conversion within the US military industrial complex from defence to civil production. After the introduction, the second section establishes a theoretical framework for the analysis, and the concept of conversion is critically examined. This section concludes, among other things, that firms can be perceived as a function of their core skills and their strategic alliances. In the next section, US defence production is discussed from a technology management perspective. Then there is an examination of three firms strategies to develop a competitive advantage in civil commercial markets: edploitation of the defence technological base; organizational and institutional changes; initiatives to affect the socio-economic framework. The success criteria for coping with reduced defence spending are established at frim, individual, local and national levels, and the firms performance with respect to these success criteria are evaluated. A major conclusion is that elements of industrial restructuring constitute an essential—although not sufficient—part of a successful transition to an economy less devoted to defence.  相似文献

This paper studies conversion factors based on the expenditure approach and evaluates the appropriateness for international comparisons of output levels in manufacturing. We apply a consistency check based on the insight that relative productivity levels should be invariant to the choice of base year. Consequently, convergence parameters and dispersion of productivity across countries should also be unaffected by this choice. The results are disappointing: relative measures of productivity depend heavily of the choice of base year and change systematically as the base years roll forward. The conclusion is insensitive to the applied method for developing conversion factors. The implication is that we cannot measure relative productivity levels in manufacturing across countries using the expenditure approach.  相似文献
