This article reports findings from a research study of two open access, multi-use, community-based family centres. Structured, qualitative interviews were conducted with 40 adult users and 40 local adult non-users of the two centres. Additionally, a profile of user characteristics was derived from a survey of users attending over a one-week period at both centres. The vast majority of users were women in their twenties, just over half of whom attended with their children. The benefits and limitations of the current functioning of open access centres are discussed, with a potential shift in emphasis along a social development model proposed.

This article examines two components of temporality that have implications for electronically mediated communication. One is the dichotomy of simultaneous/non-simultaneous communication and then the varying degrees of non-simultaneity that are possible. The other is the fundamental difference between timed and untimed communication. Timed communication is temporally based and sequential, while untimed communication, such as print and still image content, is spatially based. The article argues that there are two fundamental types of mediated communication: communication mediated across time and communication mediated across space. The implications of temporality for both forms of mediated communication are examined in detail. The implications of temporality and mediated communication for multimedia, technology convergence, and research are discussed. 相似文献

Do export processing zones draw local manufacturers into world markets – and thereby engender broader market reform – by way of a ‘demonstration effect’? The answer is likely (i) to be determined, not in the EPZ, but in the host country's national customs area, and (ii) to vary systematically with the size of the relevant market. While manufacturers from large economies are able to compete in world markets, and are therefore susceptible to the demonstration effect, their counterparts from small economies are unable to do so, and are therefore intractable. Thus, the nature of the EPZ life‐cycle, like the legacy of import‐substituting industrialisation, is in no small measure a function of market size. 相似文献

The present study examined the moderating role of health status (physical, mental, and social health) and the relationships between protective behavioral strategies utilized to reduce high-risk drinking (e.g., avoiding drinking games, setting consumption limits, or having a designated driver) and alcohol use and negative consequences in a sample of heavy drinking college students (N = 1,820). In this high risk sample, multiple regression analyses showed that stronger social health was related to increased drinking, while poorer physical, mental, and social health were related to increased alcohol negative consequences. Further, moderation effects revealed that increasing the use of protective behaviors was associated with significantly less drinking in those with stronger social health, as well as significantly lower numbers of negative consequences among participants with poorer physical and mental health. Implications for college counselors and medical personnel are discussed. 相似文献

Much of the research on adolescent friendships and school achievement has focused on in‐school friends, ignoring the potential effects of having out‐of‐school friendships. The goal of this study was to examine the relation between having relatively more in‐school friends and school achievement among a sample of over 600 12th grade students from ethnically diverse backgrounds. We found that adolescents with more in‐school friends, compared with out‐of‐school friends, had higher grade point averages (GPAs) and that adolescents with higher GPAs had more in‐school friends. These relations were mediated by academic experiences, including those shared with friends. However, as hypothesized, the social aspects of adolescents' friendships did not vary according to their percent of in‐school friends, attesting to the importance of considering both types of friendships in understanding adolescents' social experiences. None of the relations described varied according to gender or ethnicity. 相似文献

This study examined work-family interference experienced by working parents in a sample of 1888 employed adults. Role strain was examined using a multidimensional model that included family-related and work-related demands and resources. Multiple regression analyses revealed that having children under the age of six, more demanding jobs, less satisfactory child care arrangements, and less workplace support contributed significantly to higher levels of role strain. Utilization of workplace programs and benefits such as Dependent Care Accounts, Child Care Resource Guides, Parent Information Fairs, and adjusted work schedules did not significantly impact levels of work-family interference. Moreover, work and family resources were not found to have greater benefit for employees with more demanding work and family situations than for those with less demanding situations. These findings demonstrate the limited buffering ability of certain workplace and family resources, and the importance of identifying work-site as well as community-based programs and policies that have the greatest potential to assist working parents and their children. Cette étude éxamine l'intrusion travail-famille d'une expérience vécue de parents qui travaillent parmi un groupe représentatif de 1888 adultes avec emploi. La tension de rôle est éxaminée par le biais d'un modèle multidimensionnel comprenant des éxigences et ressources se rapportant à la famille et au travail. Les analyses de régression multiples démontrent que les attributs suivants contribuent de manière significative à des niveaux plus élevés de tension de rôle: avoir des enfants de moins de six ans, avoir un poste plus éxigeant, des écoles maternelles moins satisfaisantes et moins de soutien dans les lieux de travail. L'utilisation de programmes et des bénéfices de travail comme les comptes de 'Dependent Care' (c'est àdire les comptes accordant aux parents certains avantages fiscaux) des guides de ressources de crêches, des foires de renseignement pour les parents, et des horaires de travail adaptables aux besoins du travailleur, n'affectent pas significativement les niveaux de l'intrusion de travail-famille. En outre, les ressources ayant rapport au travail et à la famille ne se revelent pas plus bénéfiques pour les employés ayant une situation plus éxigeante que pour ceux dont la situation est moins éxigeante. Ces résultats démontrent la capacité protectrice limitée des certaines ressources du lieu de travail et de la famille, ainsi que l'importance d'identifier des programmes et une politique à base communitaire qui aient le potentiel le plus grand d'accorder de l'assistance aux parents qui travaillent et à leurs enfants. 相似文献

Rankings of internal rates of return to education have significantly influenced education expenditures within developing countries and lending priorities of multilateral institutions. It is widely suspected, however, that estimated education returns are subject to systematic bias. The direction and magnitude of this bias are hotly contested. This paper demonstrates that in the presence of systematic bias, idiosyncratic properties of the internal-rate-of-return mapping may cause a ranking reversal. An explicit analytical test of return-ranking legitimacy is developed and applied to select African and Asian countries. 相似文献

The scenario of established business sellers utilizing online auction markets to reach consumers and sell new products is becoming increasingly common. We propose a class of risk management tools, loosely based on the concept of financial options that can be employed by such sellers. While conceptually similar to options in financial markets, we empirically demonstrate that option instruments within auction markets cannot be developed employing similar methodologies, because the fundamental tenets of extant option pricing models do not hold within online auction markets. We provide a framework to analyze the value proposition of options to potential sellers, option‐holder behavior implications on auction processes, and seller strategies to write and price options that maximize potential revenues. We then develop an approach that enables a seller to assess the demand for options under different option price and volume scenarios. We compare option prices derived from our approach with those derived from the Black‐Scholes model ( Black & Scholes, 1973 ) and discuss the implications of the price differences. Experiments based on actual auction data suggest that options can provide significant benefits under a variety of option‐holder behavioral patterns. 相似文献

This study examined differences in the quality of relationships between immigrant parents and their adolescent children as a function of the languages with which they speak to one another. Over 620 adolescents with East Asian, Filipino, and Latin American backgrounds completed measures on parent‐adolescent language use and relationships. Adolescents who spoke in different languages with their parents reported less cohesion and discussion with their mothers and fathers than did their peers who spoke the same language with their parents. Adolescents who mutually communicated in the native language with their parents reported the highest levels of cohesion and discussion. Longitudinal analyses indicated that whereas language use did not predict differential changes in parent‐adolescent relationships over a 2‐year period, the quality of relationships did predict changes in language use. The associations between language use and relationships generally existed regardless of the families' ethnic and demographic backgrounds, and these associations did not vary across families of different backgrounds. 相似文献
