This study examined the effects of race of examiner and type of reinforcement upon the WISC-R performance of lower-class black children. A total of 120 black males were selected and assigned to either a white or black examiner to form two groups. Within each group, children were given no reinforcement, tangible reinforcement, traditional social reinforcement, or culturally relevant social reinforcement after each correct response. Children given tangible rewards, regardless of race of examiner, obtained significantly higher scores than did children given no reinforcement or children given traditional social reinforcement. Also, children given culturally relevant social reinforcement by a black examiner obtained significantly higher scores than did children given culturally relevant reinforcement by the white examiner.  相似文献

Using data on the ‘career’ paths of one thousand ‘leading scientists’ from 1450 to 1900, what is conventionally called the ‘rise of modern science’ is mapped as a changing geography of scientific practice in urban networks. Four distinctive networks of scientific practice are identified. A primate network centred on Padua and central and northern Italy in the sixteenth century expands across the Alps to become a polycentric network in the seventeenth century, which in turn dissipates into a weak polycentric network in the eighteenth century. The nineteenth century marks a huge change of scale as a primate network centred on Berlin and dominated by German-speaking universities. These geographies are interpreted as core-producing processes in Wallerstein’s modern world-system; the rise of modern scientific practice is central to the development of structures of knowledge that relate to, but do not mirror, material changes in the system.

摘要:今天的美国有1 400万的癌症存活者,其中的很多存活者中都接受了多种治疗,包括手术、放疗、化疗、靶向治疗等。这些治疗能够延长生存时间,但同时也会带来很多急慢性的副作用,危害健康,影响生活质量。体力活动(PA)与癌症生存这一领域发展迅速,主要研究PA对癌症患者的影响。基于该领域的研究进展,提出了以下10大研究问题:1)PA能够降低癌症复发风险、和/或提高存活吗?2)PA能够影响癌症治疗决策、完成率、和/或患者对治疗的反应吗?3)癌症存活者的最佳运动处方是什么?4)静坐少动行为对癌症存活者有何影响?5)癌症存活者最有效的体力活动干预方案是什么?6)哪些癌症会影响病人对PA的反应?7)癌症存活者进行体力活动时需要注意的安全问题有哪些?8)哪些具体的癌症症状可以由PA解决?9)对于癌症晚期患者,体力活动还有何作用?10)如何将体力活动研究结果转化到临床和社区肿瘤实践中来?上述问题的回答至关重要,这不仅关系到体力活动和癌症存活这一研究领域的发展,更重要的是,能够为每年数百万新诊断为癌症的病人、正在接受癌症治疗的病人、治疗结束处于恢复中的病人或是那些正在与晚期癌症抗争的病人带来福音。  相似文献

Studies of mid-twentieth century education in England and Wales have conventionally hinged on the 1944 Education Act, foregrounding policy over practice. This article considers the significance of the inter-war progressive educational movement for postwar educational developments. It presents a case study of one teacher who was active in the early ‘experimental’ years of secondary modern education, suggesting that this period was important in the making of ‘modern’ education. It seeks to complicate both negative and positive readings of ‘meritocracy’ in postwar educational history. This article also highlights the paucity of available source material for the study of the secondary modern school, arguing that attention should be paid to well-documented cases, placed in context.  相似文献

Rapid globalization of business processes stimulates many companies to dispatch their employees – business expatriates – on overseas assignments. Russia differs markedly from many other cultures in terms of specific communication norms and rules. Understanding such differences in organizational life is crucial for the success of business expatriates working there. This study employs in-depth interviews with eight Danish business expatriates who worked in Russia and examines the differences between the Danes and the Russians in terms of communication characteristics related to Hofstede’s cultural dimension power distance. This work enhances scholars’ empirical knowledge of power distance, which has rarely been investigated qualitatively.  相似文献

This brief viewpoint piece depicts educational (dis)engagements apparent in researching and (re)designing higher education in and through Accessions. Accessions, a collaborative research-design project, probed at how cultures, climates and conditions of higher education may be reproducing or reshaping social inequalities and divisions. Here, questions are asked about how these might be challenged within and potentially beyond the specific locale of one university campus. This research-design project hopes to enable a critical perspective on issues of ‘participation’, ‘impact’, ‘engagement’ and ‘internationalisation’, where regulations and measures may be resisted and disrupted.  相似文献

This paper responds to a trend of contracting out subjective well-being econometrics to demonstrate social return on investment (SROI) for evidence-based policy-making. We discuss an evolving ecology of ‘external’ research taking place ‘between’ the academy and commercial consultancy. We then contextualise this as waves of research methodologies and consultancy for the cultural sector. The new model of ‘external between’ consultancy research for policy is not only placed between the University and the market, but also facilitates discourse between policy sectors, government, the media and the academy. Specifically, it enables seductive but selective arguments for advocacy that claim authority through academic affiliation, yet are not evaluated for robustness. To critically engage with an emergent form of what Stone calls ‘causal stories’, we replicate a publicly funded externally commissioned SROI model that argues for the value of cultural activities to well-being. We find that the author’s operationalisation of participation and well-being are crucial, yet their representation of the relationship problematic, and their estimates questionable. This case study ‘re-performs’ econometric modelling national-level survey data for the cultural sector to reveal practices that create norms of expertise for policy-making that are not rigorous. We conclude that fluid claims to authority allow experimental econometric models and measures to perform across the cultural economy as if ratified. This new model of advocacy research requires closer academic consideration given the changing research funding structures and recent attention to expertise and the contracting out of public services.  相似文献
