There is empirical evidence that suggests that both technology and new work practices are skill-biased. In this paper, we analyse whether they are also age-biased. Does the introduction of new technology and new work practices reduce the demand for older workers and increase the demand for younger workers? The cross-section estimates suggest that technology is age-biased towards young, low-skilled workers. However, after sweeping away time-invariant unobserved firm effects by using a fixed effect approach, most of the significant relationships disappear. This suggests that the significant cross-section results are driven by unobserved heterogeneity between firms and are not causal effects of technology and new work practices on the demand for workers in different age groups.  相似文献

During the past decade the public debate on gay and lesbian adoptive rights has been extensive in the Norwegian media. The debate illustrates how women and men planning to raise children in homosexual family constellations challenge prevailing cultural norms and existing concepts of kinship and family. The article discusses how lesbian mothers and gay fathers understand and redefine their own family practices. An essential point in this article is the fundamental ambiguity in these families' accounts of themselves-how they simultaneously transgress and reproduce heteronormative assumptions about childhood, fatherhood, motherhood, family and kinship.  相似文献

Assisted reproduction has a minor but increasing influence on childbearing trends in advanced societies. In Denmark, the use of assisted reproduction technology (ART) has become particularly widespread. At the same time, Danish women born in the late 1950s and the 1960s experienced stabilization or even a slight increase in their mean number of children. Broad availability and widespread use of assisted reproduction may become important factors contributing to maintaining relatively high completed fertility among the younger cohorts of Danish women. To explore this idea, we analyze and project cohort trends in fertility rates among native Danish women born in 1960‐78 and examine the likely contribution of assisted reproduction to these trends. The projected proportion of children born after ART treatment shows a substantial increase from 2.1 percent among women born in 1965 to 4‐5 percent among women born in 1978, with an estimated net impact of ART (as compared with the hypothetical situation where no ART treatment was available) on the order of 3‐4 percent. When intrauterine inseminations are included, this implies that up to 7 percent of children of those native Danish women born in 1975 and later will likely be conceived by infertility treatment.  相似文献

Prior research consistently has found that older adults, despite low incomes, are more financially satisfied than younger adults. This “satisfaction paradox” is typically attributed to elders’ supposed psychological accommodation to poor financial circumstances. We advance a different explanation, one that focuses on substantial age differences in wealth and liabilities. Data are from the first wave of the Norwegian NorLAG study (n = 4,169). Findings support the hypothesis that an examination of a wider range of economic variables shows that material circumstances are more important to the financial satisfaction of the elderly than previously believed. A considerable part of the higher financial satisfaction with increasing age can thus be explained by greater assets and less debt among the aged. Nonetheless, assets and debt do not mediate this relationship at lower incomes, because older people with little income have very little accumulated wealth. As older people with little income and wealth have a much stronger tendency to be financially satisfied than their younger, equally poor counterparts, an “aging paradox” still remains in this field.  相似文献

In this paper, we analyze determinants of marital dissolution, focusing on the alleged influences from public transfers, child allowance, and child support awards. We use a Norwegian panel of 2,806 couples with information on public and private transfers in cases of divorce. The sample was observed over a 5-year period, with the purpose of registering marital dissolution. We find that the level of transfers has a significantly positive effect on divorce probability and that the distribution of transfers in favor of the wife increases this probability. Our findings are consistent with noncooperative family models allowing for inefficient outcomes.

The primary goal of this study was to test how mother and adolescent proficiency in a common language moderates the link from parenting to adolescent development. A sample of Mexican‐origin fifth‐grade adolescents (= 674, 50% female) was measured longitudinally on self‐control and aggression. Mothers were rated on observed positive discipline, warmth, and harsh discipline. Positive discipline and warm parenting predicted increases in self‐control and decreases in aggression, but only among mother–adolescent dyads who were proficient in a common language. Harsh parenting predicted decreases in self‐control and increases in aggression, but only among dyads who were not proficient in a common language. Similar results were found in a conceptual replication among a second sample of 167 Mexican‐origin adolescents.  相似文献

Nonprofits are guided by internal efforts and external mandates to build capacity. However, scholars and grant makers are hampered by varied definitions of the concept, competing but untested models, and the lack of a reliable and valid measure. This research defines nonprofit capacity as the processes, practices, and people that the organization has at its disposal that enable it to produce, perform, or deploy resources to achieve its mission. An inductive‐confirmatory two‐study approach introduces and validates the Nonprofit Capacities Instrument, a 45‐item measure of eight nonprofit capacities derived from existing instruments. The capacities are (1) financial management, (2) adaptive capacity, (3) strategic planning, (4) external communication, (5) board leadership, (6) operational capacity, (7) mission orientation, and (8) staff management. Intriguingly, this research demonstrates that nonprofit capacity is not a singular or second‐order concept, but better described in its plural form, nonprofit capacities.  相似文献

The transition of adolescents from state care to independent living is receiving increased research attention in many countries. Despite this interest, the concept of ‘transition’, though central, still remains relatively undeveloped. One main issue in comparative work is how we use language to define concepts as well as use them to analyse our findings and shape practice. ‘Transition’ over the last decade has become a key concept in the research and practice field of social work with adolescents, therefore we need to reflect on its use, its possibilities and its limitations. This paper examines selected research literature on the transition from state care to adulthood. The paper suggests that more theorisation needs to be done within the field.  相似文献

High dropout rates threaten the validity of longitudinal studies involving participants suffering from substance use disorder (SUD). The objective of this article is to evaluate strategies to improve retention. The data analysis was based on an ongoing study of long-term recovery of neurocognitive and psychosocial functions. We used traditional strategies to enhance the contact rate. Common factors in psychosocial treatments and biweekly Short Message Service (SMS; text messaging) monitoring were added to further increase the contact rate. The participants (n = 146) were recruited from treatment facilities for SUD. Assessments were measured at 3 months, 6 months, 9 months, and 12 months. This study was successful in retaining a cohort of participants who are typically characterized as having a negative prognosis because of their unstable living arrangements and incomes. Compared to those using GHB, addictive medications, and opiates, the retention rate was the lowest among participants with severe alcohol use disorder (42%).  相似文献

This article explores pre‐school reform and shifting norms of parenthood in Singapore. Whereas current education reforms in many Western countries focus on improving academic performance, pre‐school reform in Singapore de‐emphasises academic learning and urges parents to adopt ‘relaxed’ parenting practices. Analysing the position of parents in this process, we show, however, that the outcomes of this reform project are highly ambivalent. Reform makers view parents’ mindset as the main obstacle to reform, while parents experience pre‐school reform itself as prompting inconsistent messages. To account for the disorientation that this creates among parents, we draw on Bateson's concept of double bind.  相似文献
