It is argued in this article that family formation is conditioned not only by economic factors (more particularly, opportunity structures), but also by ideational changes: the economic factors produce period fluctuations that are superimposed on long-term (and often cohort-driven) ideational effects. Value orientations are explored and compared across countries and across age groups using the internationally-comparable data sets provided by the European Values Studies. The analysis indicates the existence of two latent dimensions with respect to familism: tolerance of non-conformism in family formation, and the meaning attached to parenthood. These two dimensions are not completely distinct from each other though, and both are related to religious and political variables (religiosity, ‘post-materialism’, nationalism, leftism, etc.). Theoretical links are made both with Easterlin's hypothesis which implies fluctuating fertility levels and with Simon's thesis concerning the importance of ‘civil religion’ in supporting fertility. The results are, however, largely in line with Ariès' thesis of two successive and quite distinct fertility transitions in the West, and suggest that fertility is very likely to remain at below-replacement levels.  相似文献

ABSTRACT

In the United States, sex trafficking victims have been identified at ages across the lifespan but young persons (under age 25) have been found to have unique vulnerabilities. At-risk youth, such as those who run away from home or those experiencing homelessness, are also at an increased risk of sexual exploitation. To better understand the scope and complexity of sex trafficking among these at-risk youth, a convenience sample of 131 homeless youth aged 12 to 25 years old experiencing homelessness recruited from Kentuckiana youth service providers completed an enhanced version of the Youth Experiences Survey (YES). Univariate and bivariate analyses were conducted. Results indicated that 41.2% of the homeless youth were victims of sex trafficking. The sex trafficked youth were more likely to report previous self-harm behaviors, suicide attempts, and substance use. This study not only provides support for improved service delivery, but also provides essential statistics that should inform internal policy and procedures for youth serving agencies in Kentucky and Indiana. Findings highlight a need for trauma-informed interventions designed to treat not only females but also males and LGBTQ youth. Additionally, service providers should consider partnering with victim providers and clinicians to offer therapeutic groups, individual therapy, and supportive services that increase prevention, education, and wraparound care for clients. In regards to future research, findings point towards a need to better understand the role that trauma and adverse childhood experiences may play in making young people vulnerable to sex trafficking, and encourage the need for testing prevention and early intervention practices among vulnerable youth.  相似文献

The paper describes the dynamics of employment at a firm and sector level in French industry and examines how far technological innovation can give account of it. We use a sample of 15,186 firms, over the period 1986–90. The two facts we want to explain at a firm and sector level are the net change in employment and the micro turmoil (transfers between competing firms). Innovating firms and sectors create jobs more than others over the medium run (5 years). Process innovation is more about job creation than product innovation at the firm level, but the converse is true at the sector level. This paradox is probably due to substitution effects (creative destruction).  相似文献
