Effective control of a firm's future depends upon sound pre-investment planning before further commitments are made. Therefore, the firm's situation has to be strategically characterized. In this article the author develops a strategic approach towards preplanning of investments. This approach can be helpful in suggesting a relevant investment policy. In this respect attention will be paid to acceptance criteria, financing considerations and types of commitment.  相似文献

Abstract This article presents an overview of the origins, development, rapid diffusion, and current usage of the concept of social capital in both the academic (research-oriented) and more applied (social policy) literature. Following a short quantitative survey of the appearance of the term in both theses and journals, various meanings of social capital are examined in the light of classical and contemporary sociological theory. Three main research approaches, which are based on the operationalization of social capital or its application as a heuristic device, are critically examined. These approaches are associated with the work ofJames Coleman, Pierre Bourdieu, and Robert Putnam, but there are also some references to the work of economists. The authors contend that, while social capital has value and appeal as a new term, basic theory needs greater development. In particular, attention should be paid to acknowledging the specific perspective on social capital that underlies its usage, the scale or level of analysis employed, and the value of a qualitative use of social capital.  相似文献

This article builds upon results from an empirical study of nine cases where single mothers and their teenage sons have reflected on the relationship to the absent father and on his significance for the family. The results have led us to reflect further on how the construction of a father figure is shaped. The cases are selected from ongoing interventions from the social services. The child's age at the start of the father's absence varied from birth to seven years old or more. Through analysis of the different cases of mother–son dyad, their narratives and their joint construction of a father figure, the dyad transforms into a triad with the presence of the absent father. Also discussed is the question of which underlying conditions contribute to the need for a joint construction of the father. Further, doubt is cast on the one-sided gender perspective that presupposes young men's need for an adult man as a model of masculinity. The analysis is related to Swedish legislation, emphasising the importance of ascribed biological parenthood, meaning that fathers’ right to joint custody and to visit the child have been strengthened. Along with the biological relationship, the welfare state also regulates the content of fatherhood, i.e. a state-controlled fatherhood.  相似文献

Does accumulation of knowledge occur in the social sciences, and if so, under what conditions? Three research programs in Dutch sociology are evaluated with regard to theory accumulation: figurational sociology at the University of Amsterdam: structural individualistic sociology at the University of Utrecht; and data-based sociological practice at the University of Leyden. In the first two schools, a wide international orientation is accompanied by the use of a closure mechanism, i. e. a publication and citation network that is restricted to members of the same research program. The result is a high degree of theoretical unity within a context of program diversity. The article concludes with some observations on the future of Dutch sociology, followed by a list of publications in each of the three programs.  相似文献

Corporate networks studies have been restricted mainly to the private or business sectors. Network analyses involving both corporations and state or government agencies have been extremely rare. In this paper, the intercorporate network of interlocking directorates in the Netherlands, based on 86 large corporations and financial institutions, is studied in terms of a bipartite corporate—governmental network which arises from the interlocking memberships linking these corporations with major committees, agencies and similar centers of decision in the public sector or central state mechanisms in the Netherlands. The corporations, representing 27 industrial sectors, have been related to government and state agencies in 28 policy sectors. In this exploratory analysis the two heavy industries, metal/shipbuilding and chemicals/oil stand out clearly. With respect to the 17 central firms the results demonstrate consistent correspondence between their central position in the Dutch corporate network and the degree of their interlocks with policy sectors in the state. The results also show that the interlocks are overwhelmingly linked with the two policy sectors “economic affairs” and “education and sciences”. Hence a more detailed analysis of the interlocks with these two policy sectors is reported.  相似文献

This experimental study is concerned with the impact of the timing of the resolution of risk on investment behavior, with a special focus on the role of affect. In a between-subjects design, we observe the impact of a substantial delay of risk resolution (2 days) on investment choices. Besides the resolution timing all other factors, including the timing of payout, are held constant across treatments. In addition, state-of-the-art experimental techniques from experimental economics and psychology are used for eliciting preferences and to explicitly measure emotions and personality traits. Participants put their own money at stake. Our main finding is that the timing of the resolution of risk matters for investment, modulated by the probability of investment success. Emotions are found to play a significant role in this respect and explain our main finding. Our results support recent models of decision making under risk trying to incorporate anticipatory emotions but also uncover some important shortcomings related to the dynamics of emotions.  相似文献

The transformation of Europe’s demographic regime over the past two centuries has led to considerable changes in the living arrangements of children. We study long-term changes, making use of three datasets covering the living arrangements of children born between 1850 and 1993 in the Netherlands: a historical national sample of children born between 1850 and 1922, a retrospective survey covering children born between 1923 and 1985, and data from the national population registry relating to children born between 1986 and 1993. We describe the changes in terms of whether fathers, mothers, and stepparents lived with these children at birth and at age 15. We observe a massive increase in the percentage of children growing up in a complete family between the 1850–1879 cohort and the mid-twentieth century cohorts and a return to nineteenth-century conditions in the most recent birth cohort. Time spent in a complete family increased continuously from the mid-nineteenth century on, to decrease again from the 1960s on.  相似文献

Flood risk management decisions in many countries are based on decision-support frameworks which rely on cost-benefit analyses. Such frameworks are seldom informative about the geographical distribution of risk, raising questions on the fairness of the proposed policies. In the present work, we propose a new decision criterion that accounts for the distribution of risk reduction and apply it to support flood risk management decisions on a transboundary stretch of the Rhine River. Three types of interventions are considered: embankment heightening, making Room for the River, and changing the discharge distribution of the river branches. The analysis involves solving a flood risk management problem according to four alternative formulations, based on different ethical principles. Formulations based on cost optimization lead to very poor performances in some areas for the sake of reducing the overall aggregated costs. Formulations that also include equity criteria have different results depending on how these are defined. When risk reduction is distributed equally, very poor economic performance is achieved. When risk is distributed equally, results are in line with formulations based on cost optimization, while a fairer risk distribution is achieved. Risk reduction measures also differ, with the cost optimization approach strongly favoring the leverage of changing the discharge distribution and the alternative formulations spending more on embankment heightening and Room for the River, to rebalance inequalities in risk levels. The proposed method advances risk-based decision-making by allowing to consider risk distribution aspects and their impacts on the choice of risk reduction measures.  相似文献
