This study extended Schilling's (2001) study by investigating program commitment among a larger (N = 12), older (M = 16.7 years), and more experienced (M = 5.96 years) sample of participants in the Project Effort Youth Leader Corps. Individual interviews elicited a greater number and specificity of themes. Program-related barriers included logistics, structure, and relationships, and personal-related barriers included perceived alternatives, personal characteristics, and “real-life” responsibilities. Similar to Schilling's (2001) earlier study, antecedents grouped under program environment, program structure, relationships, and personal characteristics. Participants also described outcomes in terms of behavior and emotional involvement but reported more themes related to leadership. Results are discussed in terms of consistencies and changes over time and implications for program development, expansion, and evaluation.  相似文献

This article reports the results of a study done of the item selection patterns of selective federal depositories in academic law libraries. Previously published core lists of documents for law school collections are reviewed, and the issue of a minimum percentage requirement for selection is clarified. The current study proposes a new list, one derived from research using data from the GPO Automated Item Number File. A magnetic tape of the item selections for the 143 law school libraries with depository status as of May 1983 was obtained by the author from the Government Printing Office. The tape was reformatted to show the number of libraries selecting each item. A list was then created of the 200 item numbers that appeared most frequently, and these were matched with SuDocs numbers using the List of Classes. The result is a core list of titles selected by three-fourths or more of the libraries. This list of basic titles is analyzed. Also discussed are the types of documents which appear on a list of 200 infrequently-selected item numbers (selected by 10 or 11 percent of the libraries), though the list is not reproduced here. It was found that over two-thirds of the available item numbers are selected by less than 10 percent of the libraries. Results of this research can serve as a guide to law-related documents perceived to be most useful for law school depository librarians.  相似文献

Assessment of the impact of varied forms of participatory research is enhanced by specific attention to the ripples, such work initiates in the social context. Ripples are defined as consequences either unintended or unanticipated by those carrying out the participatory research. Following a brief documentation of the range of reported ripples in reports describing participatory research, an ecological perspective drawing on the interdependence principle of ecological systems theory is presented as a framework for assessing impact by attending to ripples in the local context. Community asset mapping and social network analysis are described as examples of ways of describing and documenting environmental ripples, and strategies for both anticipating and reviewing ripples post hoc are discussed. The importance of developing cognitive maps of local ecology is stressed as critical to the assessment of the multiple potential impacts of participatory research.  相似文献

Excavating what Jeffrey Cohen [2015. Stone: An ecology of the inhuman. Minneapolis: University of Minnesota Press] calls ‘lithic ecomateriality’, in this paper we illustrate how rocks have traditionally been conceptualized through three tropes: rocks as insensate; rocks as personified; and rocks as transformative. We take up the concept of inhuman to challenge human-centric taxonomies of rocks and animacy. If rocks are not lifeless, or only considered as ‘resources’ or ‘threats’, to humans, then thinking with rocks as vital extends our ethical and political response. In the final section of the paper, we consider archives, not as a logical form of organizing knowledge, but as material, vital, and affective. We argue that when stones and archives are examined as something more than stable things – as interfactual, transcorporeal, and transmaterial co-compositions – different ethical relatings to the inhuman world become possible.  相似文献

Play is a behavioral phenomenon most commonly observed in the young of both solitary and social species. Documentation of play in cetaceans varies across species and settings. Cetacean play behavioral repertoires include a broad range of actions, such as the manipulation of diverse objects, blowing bubbles, chasing conspecifics, and swimming in spirals through the water. As is common in research on animal play, cetacean play has been grouped into categories by its form, including locomotor play, object play, and different variations of social play, such as affiliative games, play fighting, and socio-sexual play. Research has primarily focused on recording the topography of cetacean play and the demographics of the individuals engaging in play. However, these classifications are insufficient to address the possible developmental and societal functions of cetacean play behaviors, or the mechanisms with which play behaviors are spread between conspecifics and acquired by young members of cetacean populations. This article applies several developmental and social learning theories in order to organize current knowledge and guide future research.  相似文献

This forum response extends the argument made by Avery and Hains that oral traditions can be useful for including the cultures and contexts of rural areas within science instruction. To buttress the oral expressions presented in Avery and Hains, I compare oral expressions of a second rural area, 600 miles to the South, in Eastern North Carolina. I explore similarities and differences in expressions from the two areas and consider the changing rural context within Eastern North Carolina. I add a consideration of larger demographic shifts impacting many rural areas—particularly in the US South—and close with a discussion of implications for science education.  相似文献
