This study presents a novel exploration into how people with dyslexia construct personal identities within anonymous, unsolicited, postings to an online discussion forum. An interpretational phenomenological analysis suggested three key identities: learning-disabled, differently-enabled and societally-disabled. These are discussed in terms of the extent to which they draw differentially on a discourse of disability as opposed to one of individual difference. The identities are to an extent malleable and overlapping according to context. Postings suggested overall that while some contributors constructed themselves as differently-enabled and celebrated dyslexia-related abilities, others sensed themselves having a disabled identity imposed upon them. Dyslexia is perceived as negatively construed within a society which promotes literacy and cognitive acuity as essential aspects of educational and social competence and where learning differences are poorly tolerated. In addition, this study highlights the potential of online forum contributions in the study of social influences in under-researched groups. 相似文献

Emerging “prevention‐based” approaches to chemical regulation seek to minimize the use of toxic chemicals by mandating or directly incentivizing the adoption of viable safer alternative chemicals or processes. California and Maine are beginning to implement such programs, requiring manufacturers of consumer products containing certain chemicals of concern to identify and evaluate potential safer alternatives. In the European Union, the REACH program imposes similar obligations on manufacturers of certain substances of very high concern. Effective prevention‐based regulation requires regulatory alternatives analysis (RAA), a methodology for comparing and evaluating the regulated chemical or process and its alternatives across a range of relevant criteria. RAA has both public and private dimensions. To a significant degree, alternatives analysis is an aspect of product design; that is, the process by which private industry designs the goods it sells. Accordingly, an RAA method should reflect the attributes of well‐crafted product design tools used by businesses. But RAA adds health and environmental objectives to the mix of concerns taken into account by the product designer. Moreover, as part of a prevention‐based regulatory regime, it implicates important public values such as legitimacy, equity, public engagement, and accountability. Thus, an RAA should reflect both private standards and public values, and be evaluated against them. This article adopts that perspective, identifying an integrated set of design principles for RAA, and illustrating the application of those principles. 相似文献

Many different radionuclides have been released to the environment from the Savannah River Site (SRS) during the facility's operational history. However, as shown by this analysis, only a small number of the released radionuclides have been significant contributors to potential doses and risks to off-site people. This article documents the radiological critical contaminant/critical pathway analysis performed for SRS. If site missions and operations remain constant over the next 30 years, only tritium oxide releases are projected to exceed a maximally exposed individual (MEI) risk of 1.0E-06 for either the airborne or liquid pathways. The critical exposure pathways associated with site airborne releases are inhalation and vegetation consumption, whereas the critical exposure pathways associated with liquid releases are drinking water and fish consumption. For the SRS-specific, nontypical exposure pathways (i.e., recreational fishing and deer and hog hunting), cesium-137 is the critical radionuclide. 相似文献

Limits to social capital: comparing network assistance in two New Orleans neighborhoods devastated by Hurricane Katrina 总被引:1,自引:0,他引:1
Sociological research emphasizes that personal networks offer social resources in times of need and that this capacity varies by the social position of those involved. Yet rarely are sociologists able to make direct comparisons of such inequalities. This study overcomes this methodological challenge by examining network activation among residents of two unequal neighborhoods severely devastated by Hurricane Katrina. Results indicate that local network capacities of Lower Ninth Ward residents relative to those of the more affluent Lakeview neighborhood dissipated before, during, and after the disaster to erode the life chances of individual residents and the neighborhood they once constituted. 相似文献

Claims that children need both a mother and father presume that women and men parent differently in ways crucial to development but generally rely on studies that conflate gender with other family structure variables. We analyze findings from studies with designs that mitigate these problems by comparing 2‐parent families with same or different sex coparents and single‐mother with single‐father families. Strengths typically associated with married mother‐father families appear to the same extent in families with 2 mothers and potentially in those with 2 fathers. Average differences favor women over men, but parenting skills are not dichotomous or exclusive. The gender of parents correlates in novel ways with parent‐child relationships but has minor significance for children's psychological adjustment and social success. 相似文献

Restoration of ecosystem functions in urban environments is made challenging by 1) a public that often lacks understanding
of ecological principles, 2) inadequate evidence of the effectiveness of restoration practices, and 3) difficulty integrating
social and biophysical factors in studies of urban ecosystems. This paper describes a case study in which potential solutions
to these challenges were explored. We facilitated collaborative learning through public participation in the design and implementation
of an urban riparian buffer along a headwater stream in a neighborhood park, a process that was informed by ecological research.
Learning outcomes were evaluated using surveys and qualitative assessment of discussion. Results indicated that participants’
knowledge about water quality problems associated with urbanization, stormwater, and nonpoint-source pollution increased,
familiarity with stormwater management practices increased, and perceptions about the importance of stream ecosystem functions
changed. In-stream monitoring of sediment delivery, as well as direct measurements of buffer infiltration capacity, provided
early evidence of buffer effectiveness in prevention of sediment inputs to the stream and absorption of runoff from surrounding
surfaces. This study provides a useful model for integration of collaborative learning through participation, ecological restoration,
and ecological research in an urban setting. Elements deemed essential to success of this model included an opportunity for
dialog focused on a specific natural feature, sustained interaction between participants and researchers, opportunities for
hands-on participation by urban residents, and flexibility in restoration practice installation. 相似文献
