We use the NLSY97 dataset to examine the parenting‐delinquency relationship and how it is conditioned by parents’ gender, controlling for youths’ gender. Generally, neglectful and authoritarian parenting styles were associated with the highest levels of delinquency in youths. When the sample was split by parent gender, authoritarianism held up across both groups, but permissive and neglectful parenting was only significant for fathers. Independent of parenting style, boys have higher delinquency levels than girls. The strength and magnitude of this relationship is nearly identical in separate equations for mothers and fathers. Parental attachment was not a significant protective factor against delinquency for either mothers or fathers. 相似文献

This article introduces various aspects of technology business incubators (TBIs), emphasizing their increasing role in the spatial context where they are used as platforms and drivers of regional entrepreneurial ecosystems. It outlines the key themes of the emerging role of TBIs in sustainable regional development: TBI biodiversity of ecosystems; accelerating startups in the entrepreneurial university; TBI mechanisms challenged by green technology to sustain regional development; and TBIs’ connecting role between entrepreneurship education, experiential knowledge, and regional development. It proposes an agenda for future research on the role of TBIs as bridging mechanisms and drivers of entrepreneurship and regional development. 相似文献

This article evaluates the development of militant Islamic threats in Southeast Asia from the early 1990s onwards and its security implications for the Association of Southeast Asian Nations (ASEAN). The analysis contends that the extent of extremist Islamic infiltration of the region was obscured by governmental rhetoric, along with much Western opinion, which argued erroneously that ASEAN was following a unique developmental path based on shared regional values that had resulted in economic growth and political stability. However, by ignoring underlying religiously motivated tensions within and among its membership, and by refusing to countenance mature debate about them within their societies, ASEAN has succeeded only in incubating its potential nemesis. 相似文献

Abstract THIS PAPER aims to establish a framework from which we can explain our dissatisfaction with defining what we teach and what and how we assess within legal education. To what extent can we, the professions or the public, have confidence that our assessment processes predict effective professional competence? We will try to establish this framework by placing the discussion in the context of a workshop of assessment of oral skills run at the 2001 Bar Vocational Course conference. The workshop raised issues which we believe encapsulate the difficulties of measuring performance in such a way that it reliably predicts professional effectiveness. From this we will attempt to highlight the shortcomings of the current teaching, learning and assessment strategies more generally. We go on to consider the role of student reflection in support of summative assessment: is it a reliable way of helping to plug the competence‐performance gap we have identified? What is its role in summative assessment? What demands does it make on tutor and learner? Since we cannot guarantee to find the best solutions first time, we make a plea for taking the risk of failure as well as success, and trying out ideas. 相似文献

Abstract: A contamination of soft drinks in sealed bottles by organic solvents is reported: closed bottles full of soft drinks were accidentally placed on a cardboard soaked with thinner and the organic fluid subsequently fissured the bottom of the bottles and penetrated into the soft drinks without any apparent leakage of the soft drinks. Experiments were carried out to simulate the process: the penetration of different organic solvents into soft drinks through the bottom of closed bottles was tested. The penetration occurred only when the closed bottles contained carbonated soft drinks (CSD), indicating that inner pressure is a necessary condition for the fissuring of the bottles. This paper discusses environmental stress cracking of polyethylene terephthalate (PET) bottles by organic solvents and migration of chemicals to CSD. Experiments were conducted to determine the conditions in which PET can be permeable to poisoning organic products. 相似文献
