This installment of "Serials Spoken Here" covers events that transpired between late September and late October 2008. Reported herein are two Webinars, one on ONIX for Serials, the other on SUSHI, and two conferences: the eighty-fourth annual Meeting of the Potomac Technical Processing Librarians and the New England Library Association's Annual Conference. 相似文献

For the past 30 years, the definition of racial socialization has referred to how parents prepare children of color to flourish within a society structured by white supremacy. Drawing on ethnographic interviews with eight white affluent fathers, this study explores fathers' participation in white racial socialization processes. The article focuses on fathers who identify as “progressive” and examines the relationship between fathers' understandings of what it means to raise an “antiracist” child, the explicit and implicit lessons of racial socialization that follow from these understandings, and hegemonic whiteness. Findings illustrate how these fathers understand their role as a white father, how their attempts to raise antiracist children both challenge and reinforce hegemonic whiteness, and what role race and class privilege play in this process. 相似文献

The authors conducted an online survey of elementary teacher education programs within a large midwestern state to assess preservice teachers’ and teacher educators’ beliefs about and preparedness to teach financial literacy. Very few preservice teachers had meaningful experiences with personal finance in high school, college, or personal decision making. No teacher educators reported ever teaching financial literacy in their higher education roles. Only 13% of teacher educators and 25% of preservice teachers thought that it was very important to teach financial literacy in elementary education. Most teacher education faculty and preservice teachers reported that they were not well qualified to use state economics standards or the JumpStart standards for financial literacy. Preservice teachers were more confident in meeting financial literacy standards than teacher educators. Both preservice teachers and teacher educators expressed openness to collaborating with other faculty members, members of the financial service industry, and parents to teach financial literacy. Follow-up phone interviews affirmed that elementary preservice teachers and teacher educators value social studies education (and financial literacy) less than reading and mathematics education. Qualitative results also suggest that elementary preservice teachers and teacher educators would like more easily accessible resources for teaching financial literacy. 相似文献

Adult death rates are a critical indicator of population health and well-being. Wealthy countries have high-quality vital registration systems, but poor countries lack this infrastructure and must rely on estimates that are often problematic. In this article, we introduce the network survival method, a new approach for estimating adult death rates. We derive the precise conditions under which it produces consistent and unbiased estimates. Further, we develop an analytical framework for sensitivity analysis. To assess the performance of the network survival method in a realistic setting, we conducted a nationally representative survey experiment in Rwanda (n = 4,669). Network survival estimates were similar to estimates from other methods, even though the network survival estimates were made with substantially smaller samples and are based entirely on data from Rwanda, with no need for model life tables or pooling of data from other countries. Our analytic results demonstrate that the network survival method has attractive properties, and our empirical results show that this method can be used in countries where reliable estimates of adult death rates are sorely needed. 相似文献

ABSTRACTSocial work has moved firmly into a need for partnership training models, as our newest Educational Policy and Accreditation Standards explicitly call for interprofessional education (IPE). Although IPE is not a new model, we have not been consistently involved in training partnerships. Three professional schools formed partnerships to provide IPE events for social work (n = 42), medicine (n = 108), and pharmacy (n = 49) students. Social work students showed positive change on a validated measure of attitudes and beliefs regarding interprofessional practice, and debriefing included rich discussions about challenges of communication and boundaries and perceptions of hierarchy and skills of other teammates in the context of case-based learning, guided by faculty from all three professions. 相似文献

Eviction is one of the leading causes of homelessness in the U.S.A. Though permanent supportive housing (PSH) helps participants maintain housing, some still leave due to eviction. This study aimed to determine whether eviction is an important predictor of recidivism and time to return to homelessness for participants exiting PSH. The characteristics and post-exit service use of 2802 Veteran PSH participants were analyzed based on exit reason. A Cox proportional hazards survival analysis modeled risk factors for returning to homelessness within 360 days of exit. Compared with other exiters, evicted Veterans remained in the program for less time, were less likely to be receiving service-connected compensation, and used more services – particularly mental health and substance use services – following their exit, and those who returned to homelessness did so more quickly. Identifying participants who might benefit from more intensive services, project-based housing, or income supports may prevent evictions and subsequent returns to homelessness. 相似文献

A desirable function for terrestrial urban ecosystems is the mitigation of nitrogen (N) pollution associated with cities and suburbs. To assist in maximizing this function, identifying locations of sources and sinks of N in the urban environment is crucial to inform management strategies. Lawns are an extensive land cover in urbanized landscapes, and in general, they have demonstrated the capacity to function as a sink for N inputs. How N is cycled by lawns, however, is likely not uniform across the physical heterogeneity or management activities that exist in lawns. We investigated the influence of heterogeneity in light availability on N cycling in lawns that were irrigated but not fertilized. Light availability is affected by tree canopy and built structures and is, therefore, heterogeneous both within individual lawns and among lawns. Light is expected to control N retention and loss through effects on primary productivity. We experimentally examined N regulation over one calendar year by measuring net primary production (NPP), N retention using an isotopic tracer, and N leaching in existing unfertilized lawns under heterogeneous light conditions. We used a budgetary approach to estimate gaseous N loss which we assume is primarily via denitrification. Light functioned as a limiting resource for primary productivity. From low to high light conditions, annual NPP increased 177 to 430 g C?m?2?y?1 and retention of N isotope tracer increased from 50 to 65% as a result of increased retention in plants. Nitrate leaching losses were low overall and were not affected by light levels. Light availability regulated the fate of N inputs and unfertilized lawns may function as substantial sinks for reactive N through storage in the terrestrial system and N loss by denitrification. However, whether or not denitrification is generally an N sink will depend on the ratio of non-reactive (i.e., N2) to reactive (i.e., N2O, NO) denitrification products. Overall, we find that effective strategies for managing N sources and sinks in cities will likely need to consider light availability, particularly in systems receiving water subsidies via irrigation. 相似文献

Food insecurity is a common social issue and households look to assistance from food pantries, which often have difficulty supplying fresh or nutritious food. A substantial amount of produce is left in the fields, which can be collected through gleaning. In a focus group with volunteer gleaners at a faith-based nonprofit organization that attempts to fill the gaps of food insecurity, the motivations, challenges, and benefits of volunteering were examined. Volunteering in gleaning generated a sense of collective purpose and community; it addressed deeply held religious and spiritual impulses; and it puts volunteers directly in contact with nature. 相似文献
