人类的近似数量系统

近似数量系统(Approximate Number System, ANS)指个体在不需要依赖于计算和数量符号的情况下, 对一组数量进行近似表征的系统。通过总结近十年来研究者们在ANS的遗传和神经基础、干预训练等方面取得的新进展, 指出未来应综合运用各种认知神经科学研究手段立足于ANS的基因和脑生理基础研究, 进一步揭示ANS的本质和内在发生发展机制, 并将有关研究发现运用到教育教学中, 对数学困难儿童进行干预, 以提高其数学能力和适应社会的能力。     

The Importance of Community Context for Young Women’s Occupational Aspirations

The effects of community context on occupational aspirations are examined in a national sample of young women in high school in the USA in 1979 (n = 2,210). Multilevel statistical models indicate that young women living in counties with a lower divorce rate, a lower percentage of women working, and more people employed in the wholesale and retail industrial sector tended to be less likely to aspire to paid work than young women living in areas with a higher divorce rate, a higher percentage of women working, and fewer people employed in the wholesale and retail industrial sector. Community context does not affect the level of young women’s occupational aspirations as predicted by prior scholarship. An earlier version of this paper was presented at the 2006 Southern Sociological Society Annual Meetings.

Differential Effects of Strategic Planning on Community Change in Two Urban Neighborhood Coalitions

Community coalitions represent a promising approach for addressing the interrelated and multiply- determined issues affecting urban neighborhoods of concentrated poverty. The literature suggests a number of community processes that may affect coalition efforts to change and improve communities. This study uses an interrupted time-series design to examine the effects of a strategic planning intervention on community change in two urban neighborhoods in the Kansas City metropolitan area. Results showed that strategic planning was associated with increased rates of community change in the two urban neighborhood coalitions. Under appropriate conditions, such as the presence of consistent leadership, strategic planning may be a particularly effective mechanism for stimulating community change and addressing locally-determined goals in urban neighborhoods.     

Puja as One Dimension of a Sensitive,Relational Approach to Community Health Care Provision

This article compares two projects designed to train groups of rural Rajasthani women as community health workers. Through ethnographic research conducted during the training periods of each project I highlight stark differences in the management and structural approaches. The successful project recognised the importance of rituals, specifically puja, in the daily lives of participants. Both the NGO management and the trainees performed daily rituals that helped foster a supportive network. Sensitivity combined with a wider insight into the practical realities and constraints facing women in rural Rajasthan contributed to the long-term success of the second project. The first project has folded. I argue a lack of open dialogue and real connection with participants meant the project’s management were unable to adapt /tailor the program to the needs and experiences of the women involved.

The being-with of being-there

In Being and Time, Heidegger affirms that being-with or Mitsein is an essential constitution of Dasein but he does not submit this existential to the same rigorous analyses as other existentials. In this essay, Jean-Luc Nancy points to the different places where Heidegger erased the possibility of thinking an essential with that he himself opened. This erasure is due, according to Nancy, to the subordination of Mitsein to a thinking of the proper and the improper. The polarization of Being-with between an improper face, the Anyone, and a proper one, the people, which is also, as Nancy shows, a polarization between everydayness and historicity, between a being-together in exteriority (indifference and anonymity) and a being-together in interiority (union through destiny), between a solitary dying and the sacrificial death in combat, leaves the essential with unthought. This essay shows not only the tensions that arise out of Heidegger’s own analyses of Mitsein and affect the whole of Being and Time but also underlines in the end a “shortfall in thinking” inherent not only to Heidegger’s work but, as Nancy claims, to our Western tradition, a shortfall which Nancy has attempted to remedy in his Being Singular Plural. A slightly different version has been published under the title “L’être-avec de l’être-là” in Lieu-Dit 19 “Communauté” (Spring 2003). All additions in square brackets are the translators’ unless otherwise indicated. The German words in parentheses are Nancy’s additions. For the translation of citations from Being and Time, we have used the Macquarrie & Robinson’s translation which we have modified only when constrained by Nancy himself. Overall, we have tried to be faithful to the Heideggerian tone of Nancy’s text by using the accepted English translation of the central concepts of Being and Time. When we depart from the accepted translations, it is to remain true to Nancy’s paraphrases, emphases, and displacements. For example, we refrain from using “authentic” and “inauthentic.” Translated by Marie-Eve Morin Department of Philosophy, 4-97 Humanities Centre, University of Alberta, Edmonton, AB, Canada T6G 2E5 e-mail: mmorin1@ualberta.ca

Enhancing resilience: families and communities as agents for change

In this article, the Linking Human Systems (LINC) Community Resilience model, a theoretical framework for initiating and sustaining change in communities that have undergone rapid and untimely transition or loss, is presented. The model assumes that individuals, families, and communities are inherently competent and resilient, and that with appropriate support and encouragement, they can access individual and collective strengths that will allow them to transcend their loss. This competence can be nurtured by helping people regain a sense of connectedness with one another; with those who came before them; with their daily patterns, rituals, and stories that impart spiritual meaning; and with tangible resources within their community. Rather than imposing artificial support infrastructures, LINC interventions engage respected community members to act as natural agents for change. These "community links" provide a bridge between outside professionals, families, and communities, particularly in circumstances in which outside intervention may not be welcomed. The article illustrates how LINC interventions successfully have been used in communities around the world.     

A diagnostic approach to increase reusable dinnerware selection in a cafeteria

The current project tested a diagnostic approach to selecting interventions to increase patron selection of reusable dinnerware in a cafeteria. An assessment survey, completed by a sample of 43 patrons, suggested that the primary causes of wasteful behavior were (a) environmental arrangement of dinnerware options and (b) competing motivational variables. A functional relation between environmental arrangement and reusable product selection was demonstrated in a reversal design. However, the largest effect occurred as function of a multicomponent intervention involving environmental arrangement, employee involvement, and personal spoken prompts with motivational signs. The results support the use of informant assessments when designing community interventions.     

客观认识心脏介入治疗

心脏介入治疗技术作为当代心血管领域里先进技术的代表,已在我国很多医院广泛应用,取得了良好的疗效。然而,近年来由于医疗卫生体制的不完善,导致某些医务人员对它的认识出现了偏差,甚至滥用心脏介入治疗技术,给国家和患者带来沉重的负担。因此笔者认为有必要客观认识它,规范它在临床上的应用,使其真正做到为患者解除疾苦。     

Effects of exposure to community violence on school functioning: The mediating role of posttraumatic stress symptoms

This study investigated the association between exposure to community violence (ECV) and school functioning, as well as posttraumatic stress (PTS) symptoms as a potential mediator of the relationship. PTS symptoms are commonly associated with ECV, and are characterized by difficulty regulating emotions and behaviors. Thus, PTS symptomatology may be one mechanism through which community violence impacts school functioning. The community-based sample included 47 low-income African American children (aged 10-13). Results revealed that ECV was inversely related to academic performance and attendance. Symptoms of posttraumatic stress emerged as a mediator of the relation between ECV and academic performance. Results have implications for urban students who face violence in their communities, and emphasize the need for school-based mental health services.
