Some interventions by social workers, teachers and parents take time to develop but can produce, in the longer term, powerful and unexpectedly positive results. We were reminded of this in 2013, when we undertook a small qualitative study where we used feminist memory work to explore the experiences of 11 women from low socio-economic backgrounds studying social sciences at an Australian university. Of the eleven participants, seven were from social work. When asked to remember their journey into tertiary education, the women revealed memorable encounters with social workers, teachers and parents, the impact of which had lasted well into the future. We use the gardening metaphor of ‘planting a seed’ to refer to interventions that may not blossom in the short term but can bear fruit months or years later. Yet, we also note that ‘seeds of doubt’ can be planted too. We conclude by suggesting that planting seeds of possibility is a worthy but potentially overlooked professional activity. Yet, since ours is a small study, further research is warranted to explore the influence of social workers who plant seeds of possibility and whose actions help to recruit and retain socially disadvantaged students in higher education.  相似文献

The modern election campaign is a well-oiled machine. Campaigns are won by the smallest of margins. Strategists provide incentives for specific market segments, and potential voters are identified well before the writ is dropped. However, few questions are asked in those same war rooms when certain groups stay home – namely young people. Young people are largely ignored at election time, and in turn, those under 30 ignore elections. Drawing on 20 focus groups conducted in Canada in 2014, this paper compares politically engaged and less engaged communities of young people to learn how they feel about politics and political leaders. This effort builds a better understanding of why some communities of young people are less interested and engaged in politics which is vital to our understanding of turnout decline among youth, as it is these communities of young people who have almost entirely tuned out of political affairs.  相似文献

What is a social medium, and how may one moderate, isolate, and influence communicative processes within? Although scholars assume an inherent understanding of social media based on extant technology, there is no commonly accepted definition of what social media are, both functionally and theoretically, within communication studies. Given this lack of understanding, cogent theorizing regarding the uses and effects of social media has been limited. This work first draws on extant definitions of social media and subcategories (e.g., social network sites) from public relations, information technology, and management scholarship, as well as the popular press, to develop a definition of social media precise enough to embody these technologies yet robust enough to remain applicable in 2035. It then broadly explores emerging developments in the features, uses, and users of social media for which future theories will need to account. Finally, it divines and prioritizes challenges that may not yet be apparent to theorizing communication processes with and in mercurial social media. We address how social media may uniquely isolate and test communicative principles to advance our understanding of human–human and human–computer interaction. In all, this article provides a common framework to ground and facilitate future communication scholarship and beyond.  相似文献

ABSTRACT

Despite the growing population of Latino students, little has been done to recognize the potential cultural assets and resilience that Latino communities and Latino teachers can bring to the educational environment. Using Critical Race Theory, in this article, each participant shares their experiences with their Black mentors. This article shares the ways in which Black teachers continue to exemplify Black teaching excellence now with a group that isn’t Black.  相似文献

Niche partitioning reduces interspecific competition, facilitating coexistence. In urban ecosystems, however, habitat loss reduces species’ ability to spatially partition activity. Temporal partitioning may thus increase in urban areas as species, unable to avoid each other spatially, partition time to avoid competition. In Midwestern US cities, eastern gray squirrels (Sciurus carolinensis) and fox squirrels (S. niger) co-occur and compete for resources. We identified urban gray and fox squirrel activity patterns and how they vary with season, land cover, and among sites where they do and do not co-occur using camera-trap data. Both species’ activity patterns varied with season and canopy and impervious surface cover. Gray squirrel activity patterns varied in the presence of fox squirrels only in the fall, providing limited support for our temporal partitioning hypothesis. Temporal niche partitioning may thus play a role in supporting these species co-existence when competition is seasonally-elevated (e.g., fall hording), but appears less important in other seasons.

High levels of prenatal alcohol exposure (PAE) result in significant cognitive deficits in children, but the exact nature of the dose-response relationship is less well understood. To investigate this relationship, data were assembled from six longitudinal birth cohort studies examining the effects of PAE on cognitive outcomes from early school age through adolescence. Structural equation models (SEMs) are a natural approach to consider, because of the way they conceptualise multiple observed outcomes as relating to an underlying latent variable of interest, which can then be modelled as a function of exposure and other predictors of interest. However, conventional SEMs could not be fitted in this context because slightly different outcome measures were used in the six studies. In this paper we propose a multi-group Bayesian SEM that maps the unobserved cognition variable to a broad range of observed outcomes. The relation between these variables and PAE is then examined while controlling for potential confounders via propensity score adjustment. By examining different possible dose-response functions, the proposed framework is used to investigate whether there is a threshold PAE level that results in minimal cognitive deficit.  相似文献

The field of POM is steadily expanding its scope. This allows us to pursue interesting new fields of inquiry and makes us ever more relevant to the needs of practitioners. But it also increases the risk that over time our efforts will become fragmented and unfocused, causing us to slowly lose our sense of community and break up into separate camps. In this paper I ask, “What kind of new organizing framework, or ‘architecture,’ will allow us to maintain our sense of community as our interests diverge?” I describe the experience of one academic organization that faced a similar problem several years ago and how the situation was resolved. This experience leads us to propose a possible solution to Pom's emerging problem: engage with real operations managers and focus our efforts on helping them deal with the actual problems they are facing in today's complex and fast‐changing world.  相似文献
