Migration, fertility, and state policy in Hubei Province, China 总被引:1,自引:0,他引:1
Despite China s one-child family planning policy, the nation experienced a slight rise in the birth rate in the mid-1980s. Many observers attributed this rise to the heightened fertility of those rural-to-urban migrants who moved without a change in registration (temporary migrants), presumably to avoid the surveillance of family planning programs at origin and destination. Using a sequential logit analysis with life-history data from a 1988 survey of Hubei Province, we test this possibility by comparing nonmigrants, permanent migrants, and temporary migrants. While changing family planning policies have a strong impact on timing of first birth and on the likelihood of higher-order births, migrants generally do not have more children than nonmigrants. In fact, migration tends to lower the propensity to have a child. More specifically, the fertility of temporary migrants does not differ significantly from that of other women. 相似文献

Associations between interparental conflict and infant reactions were examined. Infants' history of exposure to interparental conflict and infant reactive temperament were examined as moderators. A community sample of 74 infants, aged 6–14 months, participated with their parents. Behavioral observations were made of parents' marital conflict and their infants' reactions. Parents reported on their emotional states during conflict, infants' history of exposure to interparental conflict, and infant temperament. Multilevel modeling indicated that infants showed differential responses to marital conflict; destructive and depressive conflict were associated with increased infant discussion attending and negative reactions, whereas constructive conflict was associated with decreased discussion attending and negative reactions. Infants' history of exposure to marital conflict and infant reactive temperament emerged as moderators. 相似文献

Medical tourism in Ireland, like in many Western states, is built around assumptions about individual agency, choice, possibility, and mobility. One specific form of medical tourism—the flow of women from Ireland traveling in order to secure an abortion—disrupts and contradicts these assumptions. One legacy of the bitter, contentious political and legal battles surrounding abortion in Ireland in the 1980s and 1990s has been securing the right of mobility for all pregnant Irish citizens to cross international borders to secure an abortion. However, these mobility rights are contingent upon nationality, social class, and race, and they have enabled successive Irish governments to avoid any responsibility for providing safe, legal, and affordable abortion services in Ireland. Nearly twenty years after the X case discussed here, the pregnant female body moving over international borders—entering and leaving the state—is still interpreted as problematic and threatening to the Irish state. 相似文献

In-depth interviews were conducted with African-American public relations students to explore their perceptions of public relations and the role race may play in their career success. The motivations for pursuing public relations and perceptions of the field are not different than those of other groups of students found in previous studies. However, the findings provide insights that are helpful in recruiting African-American students, and also in retaining them in the major. Central themes that emerged from the data are that it is important to have African-American role models, and that students’ view race as a fact of life that can be both a barrier and an asset. 相似文献

Both binge eating disorder (BED) and pathological gambling (PG) are characterized by impairments in impulse control. Subsyndromal
levels of PG have been associated with measures of adverse health. The nature and significance of PG features in individuals
with BED is unknown. Ninety-four patients with BED (28 men and 66 women) were classified by gambling group based on inclusionary
criteria for Diagnostic and Statistical Manual-IV (DSM-IV) PG and compared on a range of behavioral, psychological and eating
disorder (ED) psychopathology variables. One individual (1.1% of the sample) met criteria for PG, although 18.7% of patients
with BED displayed one or more DSM-IV criteria for PG, hereafter referred to as problem gambling features. Men were more likely
than women to have problem gambling features. BED patients with problem gambling features were distinguished by lower self-esteem
and greater substance problem use. After controlling for gender, findings of reduced self-esteem and increased substance problem
use among patients with problem gambling features remained significant. In patients with BED, problem gambling features are
associated with a number of heightened clinical problems. 相似文献

Same-sex sexual practices are illegal in Ethiopia; consequently, little is known about Ethiopian lesbians. We explored the lives of five Ethiopian lesbians in order to understand their sexuality from their perspectives. We were particularly interested in how they perceived their sexual identities and practices, the obstacles they faced, and how they coped with such obstacles. Three major themes emerged from their responses to a semi-structured questionnaire, which we analyze from radical, African feminist perspectives. First, these women consistently described the negative impact of Ethiopian laws on their lives. Second, all testified to experiences of sexual agency, despite repression. Finally, their responses revealed considerable diversity and fluidity regarding sexual desire, attraction, and sexual behavior, demonstrating the complexities of lesbian sexuality. We conclude with recommendations for future research and lesbian activism. 相似文献

The term ‘end-to-end’ process management is now commonplace in the language and practice of operations. Managers are encouraged to migrate from functional process management to end-to-end process management to realise a range of performance improvements. However, these improvements are often elusive; the specific challenges associated with such a migration are under-researched. This paper uses a cross-sector study to identify the challenges of end-to-end process management and to generate practical managerial guidance. Three areas are identified that demand particular managerial attention: the need to move beyond process mapping, the role of IT in process management and maintaining the process infrastructure as a strategic asset. More significantly, the findings highlight the need for greater conceptual clarity regarding the end-to-end concept itself. The existing literature suggests that scope is the primary differentiator of the end-to-end process – the requirement to manage an extended boundary from customer order through to customer fulfilment. However, this research suggests that the end-to-end concept is more complex, comprising of three core constructs with seven dimensions: scope (boundary conditions, sequence/flow and controls); scale (resources and input/output transformation) and complexity (interrelationships and orientation). End-to-end process management involves much more than an extended boundary. It requires a systemic perspective and clarity regarding controls and transforming resources. 相似文献

We study auctions for a set of commonly‐ranked items where each buyer has unit demand. This setting has promising applications in areas such as keyword auctions in the search engine advertising industry, the sale of quality‐ranked raw materials, etc. An auction mechanism suitable for this setting is the simultaneous pooled auction (SPA), where each bidder simultaneously submits a single bid and is allocated an object based on the rank of his bid among all the bids. We study how to improve the seller's expected revenue by enforcing a reserve price in an SPA. We find that the use of an appropriate reserve price may significantly increase the seller's revenue, especially when the number of items for sale is relatively large compared to the number of participating bidders. One inherent problem in the SPA is that some bidders may incur ex post losses; that is, they pay more than what they value the received objects. We propose a tailored VCG mechanism that generates the same expected revenue as the SPA does, while bidders do not incur any ex post loss. We also discuss the potential applications of this research to keyword auctions. 相似文献

It has long been known that for many joint distributions exhibiting weak dependence, the sample value of Spearman's rho is about 50% larger than the sample value of Kendall's tau. We explain this behavior by showing that for the population analogs of these statistics, the ratio of rho to tau approaches 3/2 as the joint distribution approaches that of two independent random variables. We also find sufficient conditions for determining the direction of the inequality between three times tau and twice rho when the underlying joint distribution is absolutely continuous. 相似文献
