The rate of change in the share of skilled labor has increased steadily over the past 35 years in Swedish manufacturing. A closer inspection of the period after 1970 indicates that, while relative supply changes of skilled labor seem to have been the main driving force behind the growing skill shares in manufacturing industries over the period 1970–85, an acceleration in the relative demand for skills appears to have propelled higher skill shares during the late 1980s and at the beginning of the 1990s. Consistent with such a development is the finding of an increasing degree of complementarity between knowledge capital and skilled labor, and that Swedish manufacturing firms, in recent years, have invested heavily in R&D. There is also some support for the belief that intensified competition from the South has increased the relative demand for skilled labor. However, the impact appears to be small and essentially driven by the textile industry.  相似文献

The major normative recommendations in the literature on food risk communication can be summarized in the form of seven practical principles for such communication: (1) Be honest and open. (2) Disclose incentives and conflicts of interest. (3) Take all available relevant knowledge into consideration. (4) When possible, quantify risks. (5) Describe and explain uncertainties. (6) Take all the public’s concerns into account. (7) Take the rights of individuals and groups seriously. We show that each of these proposed principles can be justified both in terms of more fundamental ethical principles and instrumentally in terms of the communicating agent’s self-interest. The mechanisms of this concordance of justifications are discussed. It is argued that the concordance is specific for areas such as food risks in which agents such as companies and public authorities are highly dependent on the public’s trust and confidence. The implications of these findings both for moral philosophy and for practical food risk communication are discussed.  相似文献

We investigate the effect of immigrants’ marriage behavior on dropout from education. To identify the causal effect, we exploit a recent Danish policy reform that generated exogenous variation in marriage behavior by a complete abolishment of marriage migration for immigrants below 24 years. The reform influenced immigrants from countries with a high historical rate of marriage migration more than immigrants from country groups with a low rate. We find that the dropout rate for males increases by 25 percentage points as a consequence of marriage to a marriage migrant, whereas the effect for females is small and mostly insignificant.  相似文献

Fishing in the Tsitsikamma National Park has officially been halted since 2001. However, the desire to fish in the Marine Protected Area remains high among the local communities in Tsitsikamma. This has led to illegal fishing practices in the park. Consequently, the reaction of the local communities was measured using semi-structured questionnaires, informal interactions, personal observations, and through a key informant workshop that was organized in the Tsitsikamma National Park. It was found that responses from local communities to fishing within the park were defined by their residence status, ethnicity, gender, income, and educational level. There is a general understanding by local communities that the purpose of the Tsitsikamma National Park is to conserve nature within its boundaries. However, there is a mismatch in the understanding of the term ‘conservation’ between the local communities and conservation officials of the South African National Parks (SANParks). Local communities consider conservation to include sustainable utilization while conservation officials from the practice pursue absolute protection of the marine fisheries resources. The majority of local communities in Tsitsikamma resent this SANParks ‘no-take’ policy on fishing. They would like access to the fisheries resources in the Tsitsikamma National Park for both subsistence and recreational purposes.  相似文献

The present paper focuses on the interactive relationship between new, technology-based firms and their network environment. The paper analyzes the mechanisms through which new, technology-based firms become immersed in innovation and manufacturing networks. The concept of embeddedness is developed and used to depict such mechanisms.A systemic evolution model of new, technology-based firms is proposed. The model depicts the evolution of new, technology-based firms in manufacturing and innovation networks. The model emphasizes the catalyzing role of new, technology-based firms in national systems of innovation.Network embeddedness is empirically explored in five case studies of Finnish new, technology-based firms. The systemic evolution model serves as an interpretative scheme for the case studies. The analysis of the organic relationship between new, technology-based firms and their systemic environment also serves to reveal the implications of embeddedness for new, technology-based firms.  相似文献

Girls outperform boys in school. We investigate whether the gender performance gap can be attributed to the fact that the teacher profession is female dominated, that is, is there a causal effect on student outcomes from having a same-sex teacher? Using data on upper-secondary school students and their teachers from the municipality of Stockholm, Sweden, we find that the gender performance differential is larger in subjects where the share of female teachers is higher. We argue, however, that this effect can not be interpreted as causal, mainly due to teacher selection into different subjects and non-random student-teacher matching. Exploring the fact that teacher turnover and student mobility give rise to variation in teacher's gender within student and subject, we estimate the effect on student outcomes of changing to a teacher of the same sex. We find no strong support for our initial hypothesis that a same-sex teacher improves student outcomes.  相似文献

Social embeddedness has been found to influence the development of new ventures, providing a basis for the trust needed for economic exchange. This study takes a novel approach to measuring embeddedness, focusing on entrepreneurs' perceived value of advice from various network partners, and shows that different types of partners exercise different influences. Analysis of a survey of 670 farm businesses shows varied embeddedness in professional and social networks, where stronger embeddedness in social networks is more associated with the development of diversified enterprises, whereas stronger professional networks is more associated with a lower incidence of such development.
