The purpose of this paper is to estimate the intra-family distribution of income and the individual demand for leisure and household production from Swedish cross-sectional household data. As a basis for the analysis, we use a collective model where each individual is characterized by his or her own utility function and divides total time between leisure, household production and market work. For the purpose of comparison, we also estimate a version that is consistent with a more traditional model of labor supply, the unitary model.

This article outlines Public Social Services’ encounters with irregular migrants in Sweden from the perspectives of institutional and street-level bureaucrats. Staff and executive considerations are influenced by a de jure exclusion of irregular migrants, which is an element of the control of migration. Staff face contradictory demands concerning international and national regulations, which leads to legal ambiguities open to discretionary powers. The aim is to explore the handling of such cases, experiences and considerations with an interest in the values that are invoked when enacting discretion and to discuss implications of the unclear legal situation. The material was obtained using web-based questionnaires. A tentative analysis confirms that the Public Social Services encounter irregular migrants and that handling differs greatly. It suggests that different approaches and the contradictory legal framework endanger the rule of law. Differing reference points appear to be invoked when enacting discretion: some related to social work and others to controlled migration. The social work values invoked by some respondents might imply an appreciation of a right to services and control of migration as independent processes and jurisdiction related to human rights that are applicable beyond the nationally framed legal status and not subordinated to policies of migration.  相似文献

This article explores the relationship between the child protection systems and the Nordic welfare state in Denmark, Finland and Norway. Despite an ideological focus on prevention and provision of a fair amount of universal services and in-home child protection services for families and children, there is, nevertheless, a relatively high number of children in the child protection system, even children placed out of their home. The outcome of child protection seems to be relatively poor. One of the problems in the present child protection systems is related to questionable service provision within the system. Other problems are about the normative foundation for the system, for example, family orientation and the least intrusive principle. Such principles are closely related to the logic of universal services, and may as such ignore the diversity of needs, rights, risks and ages of children needing protection and related services. Consequently, many principles of the present child protection systems are – and will remain – challenged by a child-centric orientation, in which valuing children's needs, rights and voice in situ are central.  相似文献

The article departs from an overarching research question: How does young people's engagement in different Internet spaces affect the development of their public orientation during adolescence? It analyses longitudinal panel data in order to explore how young people's public orientation develops during a phase in life (13–20) which is critical for political socialization. Data are derived from three waves of data collection among young people who were 13–17 years old at the time for the first data collection. The concept public orientation is measured by three indicators: young people's values, interests and everyday peer talk. These indicators are analysed with reference to respondents' Internet orientations, which we conceptualize as four separate but inter-related spaces (a news space, a space for social interaction, a game space and a creative space). The results primarily emphasize the importance of orientations towards news space and space for social interaction. Overall, the findings strongly suggest that orientations towards these spaces are related to adolescents' public orientation. The findings confirm the centrality of news and information in political socialization, but they also challenge the idea that social media facilities – such as Facebook, Twitter and blogging – enable forms of social interaction and creative production that have an overall positive impact on young people's public orientation.  相似文献

This article will start from a United Nations Educational, Scientific and Cultural Organization (UNESCO)-sponsored meeting on intergenerational programs in Dortmund, Germany, in 1999, as this was an awareness-raising moment for intergenerational programs in Europe. The connection between lifelong learning and intergenerational learning as one reason for the increased interest for intergenerational programs in the creation of European policy are discussed and connected to demography, health, aging, and well-being in policy. Therefore recent actions and reports from a European perspective are analyzed in order to reflect over the social and cultural factors that can have an impact and influence the intergenerational field in Europe in the future.  相似文献

In teacher professional development (PD), the component of collaborative participation among teachers is emphasized. Especially in video-based PD programs, the role of building up a teacher learning community and a trustful exchange among group members is important. Since general rules for productive collaboration do not exist at the beginning of a PD program, the role of a facilitator is pivotal for the successful development of a teacher learning community. In this paper, we present a new video-based PD program, the “Dialogic Video Cycle” (DVC), focusing on the improvement of classroom dialogue. In describing the DVC and the facilitation actions (“moves”), we highlight the role of the facilitator as mindful in providing teachers with new knowledge and with guiding the exchange among teachers about teaching practices and reflections. Results of a final evaluation of the program showed positive perceptions of the facilitation approach in the video-based PD program.  相似文献

If nation branding is about constructing and promoting national identity, what kind of ‘identity’ could it possibly be? This article analyses how the branded nation qualitatively differs from earlier forms of imagined communities by focusing on the tension between inward- and outward-directed dimensions of nation branding. A particular focus is placed on the concept of ‘identity’, which, it is argued, is insufficiently problematized in previous research. The discussion takes its departure in a case study of Ukraine, where all nation branding attempts came to an abrupt halt when political unrest broke out in late 2013. The political unrest led to a rapid shift in forms of concern over Ukraine, since nation branding can only be conducted in times of relative social harmony. The case further illustrates the argument that collective identity is not a main issue when branding a nation, and it is argued that a perspective of cosmopolitanism can bring new insights to the phenomenon.  相似文献

This paper exploits the discrete jump in alcohol consumption at the minimum legal drinking age (MLDA) in the USA and uses a regression discontinuity design to investigate the relationship between drinking and risky sexual behaviors among young adults. Using confidential data from the National Longitudinal Survey of Youth (1997 Cohort), we document that young adults tend to drink up to 2.1 days more once they are granted legal access to alcohol at age 21. Although the discrete jump in alcohol consumption at the MLDA is associated with an increase in the probability of having sex by up to 7.8 percentage points, it does not have a significant impact on the probability of engaging in risky sexual behaviors among young adults. We also document that the effect of the MLDA on the probability of using several different birth control methods is not significant for those who had sex in the past 4 weeks. These results are robust under alternative specifications and imply that although the MLDA law is quite effective in reducing alcohol consumption among young adults, spillover effects of this law on risky sexual behaviors are relatively limited.  相似文献

A Spatial Approach to Environmental Risk Assessment of PAH Contamination   总被引:1,自引:0,他引:1  
The extent of remediation of contaminated industrial sites depends on spatial heterogeneity of contaminant concentration and spatially explicit risk characterization. We used sequential Gaussian simulation (SGS) and indicator kriging (IK) to describe the spatial distribution of polycyclic aromatic hydrocarbons (PAHs), pH, electric conductivity, particle aggregate distribution, water holding capacity, and total organic carbon, and quantitative relations among them, in a creosote polluted soil in southern Sweden. The geostatistical analyses were combined with risk analyses, in which the total toxic equivalent concentration of the PAH mixture was calculated from the soil concentrations of individual PAHs and compared with ecotoxicological effect concentrations and regulatory threshold values in block sizes of 1.8 × 1.8 m. Most PAHs were spatially autocorrelated and appeared in several hot spots. The risk calculated by SGS was more confined to specific hot spot areas than the risk calculated by IK, and 40–50% of the site had PAH concentrations exceeding the threshold values with a probability of 80% and higher. The toxic equivalent concentration of the PAH mixture was dependent on the spatial distribution of organic carbon, showing the importance of assessing risk by a combination of measurements of PAH and organic carbon concentrations. Essentially, the same risk distribution pattern was maintained when Monte Carlo simulations were used for implementation of risk in larger (5 × 5 m), economically more feasible remediation blocks, but a smaller area became of great concern for remediation when the simulations included PAH partitioning to two separate sources, creosote and natural, of organic matter, rather than one general.  相似文献

ABSTRACT

Replication is complicated in psychological research because studies of a given psychological phenomenon can never be direct or exact replications of one another, and thus effect sizes vary from one study of the phenomenon to the next—an issue of clear importance for replication. Current large-scale replication projects represent an important step forward for assessing replicability, but provide only limited information because they have thus far been designed in a manner such that heterogeneity either cannot be assessed or is intended to be eliminated. Consequently, the nontrivial degree of heterogeneity found in these projects represents a lower bound on the true degree of heterogeneity. We recommend enriching large-scale replication projects going forward by embracing heterogeneity. We argue this is the key for assessing replicability: if effect sizes are sufficiently heterogeneous—even if the sign of the effect is consistent—the phenomenon in question does not seem particularly replicable and the theory underlying it seems poorly constructed and in need of enrichment. Uncovering why and revising theory in light of it will lead to improved theory that explains heterogeneity and increases replicability. Given this, large-scale replication projects can play an important role not only in assessing replicability but also in advancing theory.  相似文献
