Youth bulges in developing countries may carry both a potential for growth via demographic dividends, and ticking political time bombs, depending on the success of authorities in providing youth with adequate opportunities as they transit into the labour markets of the twenty-first century. In this article I examine the theoretical and empirical research on school-to-work transitions (SWT) in developing countries. After a discussion of the attempts at operationalising the concept of school-to-work transitions from a statistical point of view, I review the theoretical settings suitable for analysing the SWT. Despite an extensive search and matching literature, few models seem adapted to developing countries’ labour markets, and even fewer are empirically tested. I then examine the determinants of transition lengths at the individual and macro level. Findings indicate that education is not always associated with shorter durations to first employment, and that the reasons may be higher expectations, reservation wages, or queuing. Women generally experience longer transitions in the labour market, and evidence from labour market interventions is mixed. Many factors likely to influence the school-to-work transition have not been studied from the point of view of school-to-work transitions, however, and potential directions for future research are presented. 相似文献

Most of our knowledge about intimate partner homicide (IPH) is based on studies of men, as they outnumber women as perpetrators. From a total cohort of IPHs in Norway from 1990 to 2012 (N?=?177), we investigated differences between male (n?=?157) and female (n?=?20) perpetrators in terms of (a) IPH characteristics and sentencing issues, (b) sociodemographic, contextual and clinical factors, and (c) previous intimate partner violence. Multivariate logistic regression analyses indicated that, in comparison to male perpetrators, female perpetrators were more often in intimate partnerships without mutual children, had a greater number of accumulated welfare deficiencies, and tended to be ascribed different motives (fear and revenge) for their crimes. 相似文献

Extended blood loss results in several compensatory physiological mechanisms, including transfer of extravascular fluid into the blood circulation. If drugs are present in the body, this fluid exchange may imply that blood drug concentrations found in a trauma victim may differ from the concentrations present at the time of the trauma. To address this issue, an animal model was used to investigate the influence of blood loss on pre-existing levels of the antidepressant drug citalopram and its demethylated metabolites. Rats were administered citalopram either acutely (40 mg/kg, orally) or chronically (20 mg/kg daily, subcutaneously) for 6 days using osmotic pumps. In the experimental rats, blood loss was accomplished by withdrawing 0.8 mL blood at 10 min intervals during 70 min. In the control rats, blood was withdrawn at 0 and 70 min only. Blood, brain and lung drug concentrations were analyzed with an enantioselective HPLC method. In the chronically treated rats, the ratios between final and initial citalopram concentrations were 1.08 +/- 0.15 and 1.01 +/- 0.09 in the experimental rats and controls, respectively, indicating no major effect of blood loss. In contrast, acute oral administration resulted in increased ratios in the exsanguinated rats as compared to controls (1.84 +/- 0.50 versus 0.73 +/- 0.07; p = 0.0495). In conclusion, the observation of increased blood drug levels in the acute oral rats indicates that absorption of fluid from the gastrointestinal tract may be important in the intravascular refill. Further, in the interpretation of post-mortem blood levels of drugs, these physiological mechanisms should be taken into account. 相似文献

Contextualising Regional Innovation Systems in a Globalising Learning Economy: On Knowledge Bases and Institutional Frameworks 总被引:5,自引:0,他引:5
In order to advance the understanding of which types of regional innovation system represent effective innovation support
for what kinds of industry in different regions analyses must be contextualized by reference to the actual knowledge base
of various industries as well as to the regional and national institutional framework, which strongly shape the innovation
processes of firms. Of special importance is the linkage between the larger institutional frameworks of the national innovation
and business systems, and the character of regional innovation systems. In making the arguments about a general correspondence
between the macro-institutional characteristics of the economy and the dominant form and character of its regional innovation
systems a link is provided to the literature on ‘varieties of capitalism’ and national business systems. 相似文献

This article concerns how the municipal organisation and its leaders respond to challenges posed by the post-industrial era, in the form of shrinking employment opportunities and population decline. By developing distinct policies of supporting cultural and new economic initiatives, they depart from traditional steering modes and engage in ‘networked governance’ to safeguard community viability. This extends the scope of what we normally expect of local government, as it implies practices and de facto decision making outside the public realm. With these strategies, municipal leaders show that they are eager to do something for the people in the municipality. Their relative success in the use of governance methods might be regarded as new ways of legitimising the politicians' and the municipalities' role. In this respect, creating policies that relate to the formation of community identity may be an important asset. 相似文献

Abstract The national research and development (R&D) base has in the post-cold war era gained increased importance in order to fill new security demands. There is a broadening of the search for security relevant science and technology involving more organizations and interests, scientific disciplines and nations. The question discussed in this article is if the premises of international, free and open R&D will be(come) compromised? Will we see more scientists, in their normal scientific activities, being accused of spying? The article suggests that such risks are not unrealistic to expect. Spy cases in less democratic countries could have consequences for scientists also in other countries. Outcomes depend on, among other things, the relative strengths of academic freedom and a political Identification Friend and Foe (IFF) component. United Nations and European Union resolutions restricting science education for students from Iran and North Korea in an attempt to prevent the spread of nuclear weapons illustrate a strong IFF component. Difficulties with regard to the implementation of these resolutions and other findings are presented in the final section of the article. 相似文献

An in-depth analysis of 11 cases is used to provide insight into the neglected area of the dynamics of boards in academic
spin-offs. Drawing on stage-based, resource dependence, and social network theories, we explore board formation and changes
in board composition occurring in Norwegian and US spin-offs. We find that these theories are important complements to earlier
research on boards in technology-based new ventures. The process of board formation is mainly driven by social networks of
the founders. Although we find differences in the initial board compositions in Norwegian and US spin-offs, there is convergence
over time in subsequent board changes, which are mainly driven by the social networks of the board chair. Additions of key
board members are associated with the progress of a spin-off developing from one stage to another. Several avenues for future
research and implications are discussed. 相似文献
