This paper describes two youth participatory action research initiatives undertaken in East Palo Alto, CA, USA, as part of university–community partnerships. We discuss the process of engaging youth researchers to build youth skills, facilitate relationships with community-based organizations, and enhance study integrity. We report interview and artifact data that address: (1) how the youths' involvement in the research process affected their sense of place and self-efficacy for creating community change; (2) how the youths' interactions with adult community leaders shifted adult perceptions of youths' abilities and roles in the community; and (3) how the initiatives affected youth and adult participants' perspectives of the university.  相似文献

This essay reflects critically on Martin Heidegger's remarks about authenticity and death with the aid of Christophe Bouton's Temps et liberté (2002), translated by Christopher Macann as Time and Freedom (2014). It first raises general questions concerning the possible thematic relationship between human endeavoring (action) and the experiences of finitude and freedom. Heidegger's Being and Time is particularly useful for exploring this relationship, but certain problems emerge when using this text for accessing the essay's themes. To wit: there are good reasons for mistrusting readings of Being and Time as a “practical” guide for grounding action. Against the practical reading, the essay wishes to reclaim the ontological‐existential significance of Heidegger's text. Although Bouton's treatment of Being and Time excludes its ontological dimensions and is entirely practical, even to the point of disregarding certain theoretical risks inherent in this approach, Bouton's study is indispensable for situating Being and Time in a historical‐intellectual context, whereby the experiences of freedom and time are understood within certain metaphysical presuppositions rendering them difficult to establish together on reliable grounds. Following Bouton's lead, the essay shows that the hermeneutic differences between practical and ontological readings of Being and Time can be explored through reflections on what Heidegger might have meant by the term “Möglichkeit” (“possibility”), from which Bouton infers “freedom.” It is alleged that Bouton does not fully consider all of Heidegger's assertions regarding Möglichkeit, most problematically the claim that the human being's most essential “possibility” is its “impossibility,” that is to say, its death.  相似文献

Early Stone Age cut marks are byproducts of hominins' tool-assisted animal carcass consumption and provide a potential avenue of inference into the paleoecology of hominin carnivory. If diagnostic cut mark characteristics can be linked to flake and core tool use or the completion of distinct butchery actions, it may be possible to infer ancient tool preferences, reconstruct the consumption of specific muscular tissues, and illuminate landscape-scale stone resource use. Recently, diagnostic morphological criteria including cut mark width and depth have been used to identify marks made by different classes of experimental and archaeological stone tools (Bello, S.M., Parfitt, S.A., Stringer, C., 2009. Quantitative micromorphological analyses of cut marks produced by ancient and modern handaxes. Journal of Archaeological Science 36: 1869–1880; de Juana, S., Galan, A.B., Dominguez-Rodrigo, M., 2010. Taphonomic identification of cut marks made with lithic handaxes: an experimental study. Journal of Archaeological Science 37: 1841–1850; Dominguez-Rodrigo, M., de Juana, S., Galan, A. B., Rodriguez, M., 2009. A new protocol to differentiate trampling marks from butchery cut marks. Journal of Archaeological Science 36: 2643–2654). The work presented here adds to this experimental butchery database by using measurements of cut mark cross-section taken from bone surface molds to investigate how stone tool characteristics including flake versus core tool type, edge angle, and tool weight, influence cut mark width and depth, ultimately testing whether cut mark size is a useful indicator of tool identity. Additionally, these experiments investigate the influence of contextual factors, including butchery action, carcass size, and bone density on cut mark size. An experienced butcher used replicated Oldowan flakes and bifacial core tools in experimental trials that isolated skinning, bulk and scrap muscle defleshing, and element disarticulation cut marks on goat and cow skeletons. This sample explores cut mark traces generated under realistic butchery scenarios and suggests the following results: 1) Core and flake tools were equally efficient at completing all butchery tasks in size 1 and 3 bovid carcasses. 2) Samples of cut mark width and depth produced by core and flake tools were similar and cut marks could not be accurately classified to a known tool type. 3) Skinning and disarticulation activities produced significantly wider and deeper marks than defleshing activities. 4) Cut marks on cows tended to be wider and deeper than those on goats. 5) Cut mark width is negatively correlated with bone density when carcass size and bone portion are taken into consideration. These results suggest that a general quantitative model for inferring tool type or edge characteristics from archaeological cut mark size is not warranted.  相似文献

Innovative and effective responses to climate change require that we move beyond reliance on government to include organisations spanning different sectors, such as not‐for‐profit, private, and community groups. Interactions among these organisations in collaborative networks—or “forums”—may provide important mechanisms to successfully address climate change impacts. This paper investigates the relationships between organisational participation and involvement in forums and responses to climate change. Survey data show that people from many organisations are participating in forums and using these meeting points to discuss climate change, even when forums are intended to serve other purposes. The data suggest that participation in any type of forum is related to organisational responses to climate change. Attributes such as type of organisation and knowledge of climate change issues were also found to be related to organisational responses to climate change but these became less important when climate change was discussed in forums. The results of the research suggest that a practical way to increase the volume and variety of organisational responses to climate change may be to encourage participation in forums and/or to influence existing networks to incorporate more discussions of climate change issues.  相似文献

Steven G. Smith advocates a maximal approach to history by both historians and theorists of history, maintaining that a commitment to fullness or totality should always serve as an ideal. In my review, I try to explain what the author means by this ideal, and consider how practical such an ideal can be. He further maintains that history is mostly about shared action, and is itself an instance of shared action. I have certain reservations about this notion, though I think Smith's book deserves credit for calling attention to it.  相似文献

Policy entrepreneurship is often used to explain agenda setting through reference to the behavior of individual “change agents.” But there are still gaps in our understanding of what motivates entrepreneurs. Rational choice theory emphasizes the importance of material and nonmaterial incentives; however, it remains unclear what role institutions play. This article aims to empirically examine the relationship between incentives and institutional encouragement of innovation. Using a case study of the federal government of Canada, I find evidence that incentives matter. Government agencies with many incentives are more likely to encourage innovation than agencies with few incentives. These results underscore the importance of institutions in determining the motivations of policy entrepreneurs, and suggest future research should focus on the interplay among individual, political, and institutional factors.  相似文献

Since the enactment of reparations for Japanese American World War II internees in the early 1990s, the public debate on slavery reparations has gained momentum. Recently, a number of states and the U.S. House of Representatives have issued formal apologies for slavery. In light of this debate, it may be important for policymakers, as well as policy researchers, to better understand public opinion on this issue. At present, not much is known other than that most Americans oppose reparations. However, public opinion surveys yield widely varying population estimates. These differences may represent random error by an uninformed public or they may reflect complex considerations about "who" should be compensated "by whom" in "what form" and "for what" injustice. Using the results of a nationally representative question wording experiment ( n =  2,001) this article investigates whether opposition to slavery reparations is unqualified, or whether it depends on the specific policy design. Since data collection was completed before Virginia became the first state to apologize for slavery in February 2007, the study offers a window into the formation of public opinion prior to elite policy enactment. Results suggest that the public carefully distinguishes between different reparations proposals and that policymakers, as well as policy researchers, may have to be very specific when addressing an issue of this complexity.  相似文献
