Although recent studies examine overall fertility trends in West Africa, few using advanced demographic techniques focus on adolescents. This study explores long‐term patterns of adolescent childbearing in 12 West African countries using 51 Demographic and Health Surveys covering birth cohorts that span 54 years (1940–1994). We employ classic demographic measures as well as disaggregation by early‐ (10–14 years old), middle‐ (15–17), and late adolescence (18–19). Cohort‐based estimates of total adolescent births, parity progression ratios, and rapid repeat birth probabilities reveal little change over time. Most women begin childbearing in adolescence, the progression to additional adolescent births remains common, and the incidence of rapid repeat births is high. In recent cohorts, women exit adolescence with an average of between 0.4 (Ghana) to 1.3 (Niger) births. Contrary to common assumptions, it is women commencing motherhood in early‐ and middle‐, not later adolescence, who account for most West African adolescent fertility.  相似文献

Research suggests the relationship between pleasure and condom use during penile–vaginal intercourse (PVI) is associated with relationship status. This online study examined pleasure ratings and condom use at last PVI, stratifying by partner type, among a national sample of Canadian university students. Participants were 715 undergraduates (60.7% women, 39.3% men) who reported on their most recent sexual experience. Condom use decreased with level of relationship commitment, whereas ratings of pleasure increased. Overall, participants were more likely to rate their most recent PVI as Very pleasurable when condoms were not used compared to when condoms were used. However, when stratified by partner type, these differences largely disappeared. For women, with one exception, there were no differences in pleasure between PVI with and without condoms across most partner-type categories. Women in committed dating relationships were more likely to report their last PVI as very pleasurable if condoms were not used than women in these same relationships who had used condoms. Across relationship categories, men who did and did not use condoms did not differ in terms of their pleasure ratings. The results of this study suggest relationship context should be taken into account when assessing condom use experiences.  相似文献

Limited research on parental well‐being by child age suggests that parents are better off with very young children despite intense time demands of caring for them. This study uses the American Time Use Survey Well‐Being Module (N = 18,124) to assess how parents feel in activities with children of different ages. Results show that parents are worse off with adolescent children relative to young children. Parents report the lowest levels of happiness with adolescents relative to younger children, and mothers report more stress and less meaning with adolescents. Controlling for contextual features of parenting including activity type, solo parenting, and restorative time does not fully account for the adolescent disadvantage in fathers' happiness or mothers' stress. This study highlights adolescence as a particularly difficult stage for parental well‐being and shows that mothers shoulder stress that fathers do not, even after accounting for differences in the context of their parenting activities.  相似文献

We introduce a specific duration model to analyze the prediction of the credit rating migration. We consider hazard rate processes based on multi‐state autoregressive conditional duration models. To take account of the economic context, we model the conditional mean of the duration between two ratings by means of a latent process. To this purpose, a dynamic‐ordered probit model is developed to describe the directions taken by the ratings in the presence of multiple states. As an illustration, we study the migration of credit rating during periods before and after the financial crisis. (JEL C14, C41, G24)  相似文献

This study theorizes and empirically tests a conceptual framework to understand how a company can better motivate its employees to carry out persistent prosocial behavior and develop positive organization-employee relationships through corporate social responsibility (CSR) involvement. A managerial approach, employee participative decision making in CSR, is examined for its impact on the prosocial behavioral outcome among employees and the relational outcome for the organization. Furthermore, a psychological mechanism that emphasizes employees’ perceived need satisfaction is examined as the underlying explanation that drives the effectiveness of the managerial approach. The study results support that empowering employees to co-construct CSR decisions with top management is effective in satisfying employees’ basic psychological needs for autonomy, competence, and relatedness. This in turn increases the employees’ intention to maintain long-lasting involvement in CSR and improves their relationships with the company. This study provides important implications for public relations professionals and organizational leaders on how to improve their internal CSR communication and involvement practice and cultivate desirable organization-employee relationships.  相似文献

Abstract

Parent-carers need support to continue to care for their child with significant disability in their home. There has, however, been little evidence that respite interventions have consistent or enduring beneficial effects on carer well-being. This article reports the findings of a qualitative study which adopted an Appreciative Inquiry philosophy to interview parent-carers of children with significant intellectual and/or developmental disabilities on how formal support services have helped them maintain their health and well-being, and disability support staff on how they help such parent-carers foster their health and well-being. We conclude that better communication and collaboration between service providers and users, more targeted training of workers, and embracing a person-centred and family-centred approach to respite services are needed. In addition, clearer definition and communication of the scope of respite services are required to best support families of children with significant disability in their home.  相似文献

If voters vote strategically, is it useful to offer them the possibility of expressing nuanced opinions, or would they always overstate the intensity of their preferences? For additive voting rules, say that a ballot is extremal if it is neither abstention-like nor can be expressed as a mixture of the available ballots. We give a sufficient condition for strategic equivalence: if two rules share the same set of extremal ballots (up to an homothetic transformation), they are strategically equivalent in large elections. This condition is also necessary for the strategic equivalence of positional rules. These results do not hold for small electorates.  相似文献

Recent energy and climate policies, particularly in the developed world, have increased demand for bioenergy2 as an alternative, which has led to both direct and indirect land-use changes and an array of environmental and socio-economic concerns. A comprehensive understanding of the land-use dynamics of bioenergy crop production is essential for the development of sustainable bioenergy and land-use policies. In this paper, we review the patterns and dynamics of land-use change associated with bioenergy crops (hereafter referred to as ’bioenergy-driven land-use change’). The review focuses on four regions as the most prominent locations in which these patterns and changes occur: Brazil; Indonesia and Malaysia; the United States of America (U.S.A.); and the European Union (EU). The review confirms that bioenergy-driven land-use change has affected and will impact most severely on the ’land- and resource-abundant’ developing regions, such as Brazil, where economic development takes priority over sustainable land-use policies, and the enforcement capability is limited. Opportunities for more effective policy are available through the development of international climate change policy (e.g. REDD under the UNFCCC), and certification criteria for sustainable bioenergy products (e.g. EU RED). However, bioenergy produced from no and/or less land-using feedstocks (e.g. wastes and residues), and their associated technologies must be given higher priority to minimise bioenergy-driven land-use change and its negative impacts.  相似文献

The effects of maternal responsiveness on infant responsiveness and behavior in the Still‐Face Task were longitudinally examined through infants' first 3 months. Maternal vocal responsiveness and infant vocal and smiling responsiveness significantly increased when infants were 2 months of age. Mothers showed continuity of individual differences in vocal responsiveness from the infants' newborn period. Maternal responsiveness predicted infant responsiveness within and across sessions. Compared with infants with low‐responsive mothers, infants with high‐responsive mothers were more attentive and affectively engaged during the Still‐Face Task from 1 month of age. Infants with high‐responsive mothers discriminated between the task phases with their smiling at 1 month, a month before infants with low‐responsive mothers did so. Infants in both groups discriminated between the phases with their attention and nondistress vocalizations throughout their first 3 months. Results suggest that maternal responsiveness influences infant responsiveness and facilitates infants' engagement and expectations for social interaction.  相似文献
