Sensation Seeking and Impulsivity: Combined Associations with Risky Sexual Behavior in a Large Sample of Young Adults

Although prior studies have shown that sensation seeking and impulsive decision-making are related to sexual risk-taking, it is still unclear whether these personality traits operate independently or synergistically. The purpose of this study was to elucidate the joint contribution of these personality traits to HIV and sexually transmitted disease (STD) risk behaviors using data from a large sample of sexually active young adults (N = 2,386). Regression modeling indicated that both sensation seeking and impulsive decision-making were consistently associated with sexual risk behaviors across 11 risk-related outcomes. Results further indicated that sensation seeking and impulsive decision-making operated synergistically with respect to the outcome variables of sex acts using drugs, acts with a partner using alcohol, and acts with a partner using drugs. In contrast to this, sensation seeking and impulsive decision-making operated independently with respect to the other sexual risk outcomes. Theoretical implications, as well as implications for HIV/STD prevention among high sensation seekers and impulsive decision-makers, are discussed.     

European Regional Populations: Current Trends, Future Pathways, and Policy Options

Europe is currently experiencing an ageing population and slowing population growth of both the total and working-age populations. These trends are likely to continue. Even though population ageing will affect all European regions, different regions will be affected in different ways. Even under favorable conditions, 35–40?% of all NUTS2 regions will face a labor force decline. If economic conditions are poor, some regions may continue to grow, but 55–70?% of the regions will see a labor force decline by 10?% or more. In most regions of Eastern Europe, the labor force may decrease by more than 30?%. To keep regions prosperous (maintaining competitiveness) and to avoid worse inequality (maintaining cohesion), policy-makers must find ways to cope with these challenges through new fiscal and social policies, though policies directly affecting demographic and migratory trends may also be needed.     

Ethnic population projections for the UK, 2001–2051

This paper reports on projections of the United Kingdom’s ethnic group populations for 2001–2051. For the years 2001–2007 we estimate fertility rates, survival probabilities, internal migration probabilities and international migration flows for 16 ethnic groups and 355 UK areas. We make assumptions about future component rates, probabilities and flows and feed these into our projection model. This model is a cohort-component model specified for single years of age to 100+. To handle this large state space, we employed a bi-regional model. We implement four projections: (1) a benchmark projection that uses the component inputs for 2001; (2) a trend projection where assumptions beyond 2007 are adjusted to those in the UK 2008-based National Population Projections (NPP); (3) a projection that modifies the NPP assumptions and (4) a projection that uses a different emigration assumption. The projected UK population ranges between a low of 63 millions in 2051 under the first projection to a high of 79 million in the third projection. Under all projections ethnic composition continues to change: the White British, White Irish and Black Caribbean groups experience the slowest growth and lose population share; the Other White and Mixed groups to experience relative increases in share; South Asian groups grow strongly as do the Chinese and Other Ethnic groups. The ethnic minority share of the population increases from 13% (2001) to 25% in the trend projection but to only 20% under our modified emigration projection. However, what is certain is that the UK can look forward to be becoming a more diverse nation by mid-century.     

走向一种为了共同福祉的建设性后现代主义

与现代主义相比,建设性后现代主义更有助于实现生态文明以及人类社会的和谐发展.二者形成鲜明的对比:现代主义把主体自我视为意义和价值的唯一源泉,后现代主义则以群体为先;现代主义是以竞争和支配的模式为基础,后现代主义的核心价值观却是合作;现代主义认为社会为个人而存在,后现代主义者则关心每一个体的幸福;现代主义主张事物之间的机械性关联,后现代主义则强调一切生物间的有机联系;现代主义常常自我鼓吹,否弃传统,后现代主义却能够尊重传统智慧.     

Factors Affecting Birth Rates Among Black Women 20--24 Years of Age: A Trend Analysis (January 1972--March 1992)

This research provides a multivariate explanation of monthly (N = 243) birth rate variation for African-American women 20--24 years of age using time series analysis. The research explains both seasonal and intermediate variation in these birth rates. The independent variables were selected for their relationship to: economic understandings of fertility; developing understandings of the relationship of photoperiod to reproductive functioning; routine activity theory; and the relationship of birth rates to quality of life perspectives. The findings of this research are interpreted with respect to important developments and understandings in the quality of life literature. Concepts of 'compensatory validation' and 'contextual compatibility' are derived from quality of life understandings and Rainwater's (1974) concept of 'validating activities'. The previously identified importance of domains of intimacy, sexual activity and family life (Cummins, 1996; Alfonso et al., 1996) are related to empirical findings concerning the conception of children and incorporated into these theoretical concepts. Nine explanatory variables were selected. Theoretical, research and policy implications are summarized.     

The Effect of Leap Years and Seasonal Trends on the Birthday Problem

Most data have a space and time label associated with them; data that are close together are usually more correlated than those that are far apart. Prediction (or forecasting) of a process at a particular label where there is no datum, from observed nearby data, is the subject of this article. One approach, known as geostatistics, is featured, from which linear methods of spatial prediction (kriging) will be considered. Brief reference is made to other linear/nonlinear, stochastic/deterministic predictors. The (linear) geostatistical method is applied to piezometric-head data around a potential nuclear-waste repository site.     

Considering religion and beliefs in child protection and safeguarding work: is any consensus emerging?

Diverse, but significant, phenomena have combined to raise both the profile of issues related to religion and child abuse and the need for professionals to understand and respond appropriately to them. The nature of some of these issues is explored and attempts made to clarify them. Data collected by the author primarily from questionnaires completed by professionals involved in child protection and safeguarding work are analysed and discussed. Some patterns are identified and explored. Finally, it is suggested that, despite the apparent emergence of a more general recognition and acknowledgement of these issues amongst many professionals, relevant day‐to‐day practice remains largely dependent on individual views and attitudes. Moreover, practitioners are able to continue with ‘religion‐blind’ and ‘belief‐blind’ approaches without these being significantly challenged by agency policies or by professional cultures.
