Obviously Sir Francis Bacon's phrase “Knowledge is Power” refers not only to natural science and technology, aiming at understanding natural phenomena and obtaining material wealth, but also to social sciences and technologies, concerning social ideals and seeking harmonious and sustainable development in society. Innovation and entrepreneurship based on natural sciences and technologies have facilitated science and technology parks in the past; however, innovation and entrepreneurship based on social sciences and technologies are now laying the foundations for the concept of a “social innovation park”. The distinctive characteristics of social innovation parks and how social academic entrepreneurship is fostered by them through strategy and policy-making at local, national and global levels are explored in this study.  相似文献

Abstract

The psychostimulants are the most widely used treatment modality for attention deficit/hyperactivity disorder (ADHD). Although positive responses to psychostimulants have been demonstrated, 46% of adults with ADHD, on average, are nonresponsive or cannot tolerate the medications because of adverse effects. We reviewed the charts of 43 students treated with pemoline and studied parameters of nonresponse. Sixteen (37%) met the study definition of nonresponse. Of these, 5 (12%) were symptom nonresponders and 11 (25%) were nonresponders because of adverse effects. We found a significant relationship between age and nonresponse resulting from adverse effects, yet no other factors predicted nonresponse to pemoline. Clinicians should consider using smaller starting doses of pemoline in adults to minimize adverse effects.  相似文献

This paper proposes the bivariate probit selection model (BPSM) as an alternative to the traditional Mare model for analyzing educational transitions. The BPSM accounts for selection on unobserved variables by allowing for unobserved variables which affect the probability of making educational transitions to be correlated across transitions. We use simulated and real data to illustrate how the BPSM improves on the traditional Mare model in terms of correcting for selection bias and providing credible estimates of the effect of family background on educational success. We conclude that models which account for selection on unobserved variables and high-quality data are both required in order to estimate credible educational transition models.  相似文献

For the past two decades, Nordic social policy has been subject to a range of serious challenges, among which economic problems and critiques by neo-classical economists have been most prominent. This article raises the question whether Nordic social policy has significantly changed during this period of challenges. Based on an empirical analysis of social expenditure data and three central social security programs, this article provides evidence that changes in Nordic social policy over this period have, in fact, been relatively minor. Indeed, the four welfare states of Denmark, Finland, Norway and Sweden have shown remarkable resilience considering the harsh challenges that they have been exposed to since the early 1980s.  相似文献

Normative criteria for evaluations of economic and social outcomes are often formulated in terms of social welfare functions which are essentially and importantly non-satiable. However, there are good reasons to consider certain normative criteria and many policy objectives to be capped, i.e. bounded, and thus satiable provided sufficient resources are made available for their satisfaction. Inspired by the Foster–Greer–Thorbecke class of indicators, this paper uses an interdisciplinary approach to develop a model for assessing outcomes in terms of capped objectives based on an understanding of individual shortfalls from the objective, denoted needs. We present an indicator to measure need satisfaction in a population of individuals with heterogeneous needs and highlight an aggregation problem under scarcity. For such situations, we develop three ways in which the indicator can be weighted that reflect respectively concerns over the frequency, depth and severity of the need shortfalls and show that normative evaluations based on these weighting schemes can conflict, yielding mutually inconsistent outcome rankings. The indicator can be adapted to measure a wide variety of phenomena, e.g. health needs, education shortfalls, deprivation, etc., and it is suited for targeting exercises and other policy implementations. In particular, it allows for exogenous weighting schemes, i.e. weights that can incorporate non-shortfall characteristics relevant for the evaluation, e.g. age, gender, ethnicity, etc. The indicator thus enables new ways for researchers to promote and study satiable objectives in a wide variety of contexts relevant to economic and social policy, e.g. human development programs, poverty reduction, healthcare policies, etc.  相似文献

Equality of opportunity is an ethical goal with almost universal appeal. The interpretation taken here is that a society has achieved equality of opportunity if it is the case that what individuals accomplish, with respect to some desirable objective, is determined wholly by their choices and personal effort, rather than by circumstances beyond their control. We use data for Swedish men born between 1955 and 1967 for whom we measure the distribution of long-run income, as well as several important background circumstances, such as parental education and income, family structure and own IQ before adulthood. We address the question: in Sweden, given its present constellation of social policies and institutions, to what extent is existing income inequality due to circumstances, as opposed to ‘effort’? Our results suggest that several circumstances, importantly both parental income and own IQ, are important for long-run income inequality, but that variations in individual effort account for the most part of that inequality.  相似文献

A limited number of species and genera currently dominate the tree stock in streets and urban sites. There has been considerable and persistent argumentation for the necessity of using a more varied and stress-tolerant selection of tree species. This paper reports results from a dendroecological study of six steppe forest reserves in north-east Romania and in the adjacent part of the Republic of Moldavia, where water stress regimes during the growing season and winter temperatures are comparable to those of inner city environments in northern parts of Central Europe and adjoining milder parts of Northern Europe (CNE-region). In each forest reserve, tree growth patterns were studied in five 20 m × 20 m plots, resulting in a total of 30 plots with an allocated area of 1.2 hectares. For all trees, height and diameter were measured and related to tree age by coring in order to detect the species growth and performance in these sites. In total 23 tree species were found, 13 of which were represented by 25 or more individuals with documented good growth in the study plots. The majority of these 13 species have very limited use in urban greenery in the CNE-region today and thus have the potential to increase the species diversity of the current urban tree population through further selection work.  相似文献

During the last three decades, most developed countries have experienced increasing income inequality. Using Danish register data from 1992 to 2007 for all private‐sector employees, we confirm that income inequality has increased in Denmark. We also observe an increase in the relative employment of highly educated individuals, as well as differential income growth rates across employee subgroups where, in particular, managers experienced significant real income progression. We use an equilibrium search framework with on‐the‐job search to study the interplay between skill‐upgrading, management compensation, and income inequality. In this model we can determine the management and education premia. We can also show that when our model is exposed to skill‐upgrading, it is capable of producing income dynamics similar to those observed in the Danish income distribution. (JEL J3, J6, M5)  相似文献
