This teaching note examines the use of intentional, identity-centered spaces in the social work classroom. We discuss the use of identity-based caucusing as a means of centering the embodied and lived experiences of students in the social work classroom, drawing from previous classroom experiences in an MSW foundation course on social justice at a large public university. Specifically, we consider borderland perspectives and postcolonial constructions of third spaces and their usefulness in social work pedagogy. In particular, we pose questions regarding the use of third space caucusing as a means of embracing and affirming both/and, neither/nor identity positionalities. We also consider possibilities of student-centered, critical pedagogical approaches while paying attention to the unique challenges and contexts of social work education.  相似文献

Urbanization has been identified as a threat to biodiversity due to landscape modifications. Studies of parasite ecology in urbanized areas lagged behind those made on macro organisms. Here we studied infection prevalence of haemosporidian parasites in an avian community of an urban forest from Germany, and its relationship with bird abundance and body mass. We used PCR to amplify a fragment of the mtDNA cyt b gene to determine the infection status of birds, and bird point counts to determine bird relative abundances. The avifauna was dominated by two small sized insectivore passerines (Parus major, Cyanistes caeruleus), representing ~40 % of the total bird records. The highest haemosporidian prevalence was recorded for Turdus philomelos (100 %) and for Fringilla coelebs (75 %). Bird abundance and body mass were positively associated with infection status for two haemosporidian genera: Plasmodium and Leucocytozoon. Infection rate was lower in juveniles compared to adult birds. We recorded a total of 7 Plasmodium, 26 Haemoproteus, and 10 Leucocytozoon lineages. Avian malaria (P. relictum) was detected infecting 5 individuals of P. major, the most abundant species in the community. These results, together with those of previous studies at the same site, suggest that potentially any of the genetic haemosporidian lineages detected in this urban forest can be transmitted across native and pet bird species, and to species of conservation concern housed at aviaries.  相似文献

Urbanization poses threats to earth’s biota, and retention of remnant native habitat in protected areas within expanding urban boundaries may help alleviate threats to wildlife. However, it is unclear for nearly all nonsynanthropic (i.e., not benefiting from an association with humans) species whether vital rates in urban habitats can sustain populations or if populations persist only through immigration from outside the urban boundary. We conducted a three-year study of spotted towhees (Aves: Pipilo maculatus) breeding in four undeveloped parks in Portland, OR, USA, to measure park-specific seasonal reproductive output (F) and annual adult survival (SA). We developed a stochastic model that combined F and SA with an estimate of first-year survival to measure population growth rate (λ) in all parks assumed to be closed to immigration. F differed among parks but SA did not. Relatively high F was possible because many pairs raised >1 brood/season. When combined with empirical estimates of survival through the 30-day period of post-fledging parental care (SD = 0.645), only 2 of 4 parks were self-sustaining (i.e., λ > 1.0). However, SD reflected substantial loss of fledglings to domestic cats (Felis catus). Assuming no loss to cats and either partial compensatory or additive mortality of fledglings substantially improved prospects of population persistence for declining (sink) populations. Moreover, allowing low levels of immigration to sinks reversed population declines in most parks even when vital rates were insufficient to maintain populations. Our results suggest that nonsynanthropic bird species can persist in urban landscapes, but also that offspring mortality in the post-fledging period may be a critical determinant of population viability.  相似文献

Previous research has found that kinematic features of interactions, such as spatial proximity, capture adult visual attention. The current research uses online measures of gaze behavior to determine attentional capture to objects with reduced interobject spacing in adults as well as infants at 5 and 12 months. The three age groups observed three identical geometrical shapes that moved randomly. Relative distance between the objects was mapped and intervals of high and low spatial proximity were identified. Findings demonstrate that only adults and 12‐month‐olds look significantly more at the objects that are close during instances of high spatial proximity, while 5‐month‐olds look at chance. The findings speak for a developmental trend in oculomotor processes, where a bias to look at objects with high spatial proximity develops within the first year of life.  相似文献

Family formation changed dramatically over the 20th century in the United States. The impact of these changes on childbearing has primarily been studied in terms of nonmarital fertility. However, changes in family formation behavior also have implications for fertility within marriage. The authors used data from 10 fertility surveys to describe changes in the timing of marital childbearing from the 1940s through the 21st century for non‐Hispanic White and non‐Hispanic Black women. Based on harmonized data from the Integrated Fertility Survey Series, the results suggest increasing divergence in fertility timing for White women. A growing proportion of marriages begin with a premarital conception; at the same time, an increasing proportion of White women are postponing fertility within marriage. For Black women, marital fertility is increasingly postponed beyond the early years of marriage. Evaluating the sequencing of marriage and parenthood over time is critical to understanding the changing meaning of marriage.  相似文献

Studies across diverse national contexts reliably show that married men earn more than unmarried men, but the mechanisms responsible for this are still disputed. This article explores the male marriage wage premium from a new perspective, using longitudinal qualitative data from Russia (N = 94). Qualitative research is particularly suited to identifying underlying processes and, by analyzing men's accounts of the influence of their marital trajectories on their work, the authors were able to reexamine existing hypotheses and develop new ones. They propose 4 mechanisms that they hypothesize can influence men's work motivation and performance: premarital planning, 2 distinct “breadwinner” effects using expectancy and self determination theory, and monitoring by wives. They integrate these mechanisms within gender theory, arguing that the treatment aspect of the male marriage wage premium is an outcome of the “coproduction” of masculinity within marriage. Their recontextualization of existing theory also enables them to reveal weaknesses in the specialization hypothesis.  相似文献

This article considers the extent and nature of social work and social care practitioners' experience of working with service users whose lives are affected by the problematic use of alcohol or other drugs (AOD). It draws on the findings of a national study of ‘working with alcohol and drug use’ which was conducted in England in 2010–2011. The study reported here comprised an online survey of front-line practitioners (n = 597), complemented by 12 practitioner focus groups and interviews with 21 key informants from participating local authorities and substance use treatment services. This paper focuses primarily on data from one element of the survey. Findings indicate that the great majority of staff encountered service users who are affected by AOD problems at some level, although there were differences between groups of practitioners in the extent and nature of AOD problems for different groups of service users. The differential experiences of staff according to their client groups underlines the need for education and professional development not only to provide training on working with AOD but to ensure that training is contextualised and relevant to practitioners across the range of social work and social care services.  相似文献

An exploratory teaching approach was inspired by the communicative experiences of d/Deaf students in tertiary education. ‘Theory of Mind’ has been used by some to describe the capacity to appreciate that views of others may be different from our own, a concept that could provide a different way for students and educators to understand the barriers identified. An adapted assessment highlighted challenges faced and a communication group provided opportunities for extending personal understandings of social settings. Emerging ideas to inform practice and potential implications for inclusion have relevance for other contexts.  相似文献
