抱箍法在西潼高速公路盖梁施工中的运用

抱箍法是利用抱箍和墩柱夹紧产生的静摩擦力来克服盖梁及临时设施重量的一种盖梁施工方法。作为一种无支架施工工艺,相对于传统的满堂支架支撑体系施工工艺,不仅节约材料,保证墩美观,且节省了材料周转时间,加快施工进度,在应用中取得了良好效果。

科学数据产品的质量管理基础

科学数据的质量越高,人们可以越快获得更准确的结论,社会更容易从中获益.要改进科学数据的质量,必须清楚地了解科学数据的性质及其产生过程.本文以科学决策过程为背景,提出数据产品和数据质量的定义,其中假设了两种典型的情景:收集观测数据及进行以文献为基础的研究.然后分析与全面质量管理(TQM)理念相关的两个延伸学科--全面信息质量管理(TIQM)和全面数据质量管理(TDQM),以确定科学数据质量的管理是否有别于其他数据和信息的管理.本文提出规划、评估/保障、控制和持续改进的建议,重点放在将质量设计到生产流程中去,而不是依赖大量的检验.     

Classroom contextual effects of race on children's peer nominations

Black children generally receive poorer sociometric nominations compared with Whites. This effect is not fully understood because Black children rarely hold a classroom majority and teachers' race is rarely investigated. Research from a person-environment perspective suggests that the effects of children's race depend on the racial composition of the classroom and society's racial attitudes. Sociometric nominations were obtained from 1,268 5th graders, between 9 and 11 years old (53% Black), across 57 classrooms (3-95% Black students). Half of the teachers were Black. The results indicated that ratings of Black children were more influenced by the racial context of classrooms than were ratings of White children. The implications of this study are discussed in relation to group dynamics and racial discrimination.     

Disclosure and secrecy in adolescent-parent relationships

Beliefs about parents' legitimate authority and adolescents' obligations to disclose to parents and actual disclosure and secrecy in different domains were examined in 276 ethnically diverse, lower middle-class 9th and 12th graders (Ms=14.62 and 17.40 years) and their parents (n=249). Adolescents were seen as more obligated to disclose prudential issues and less obligated to disclose personal than moral, conventional, and multifaceted issues; parents viewed adolescents as more obligated to disclose to parents than adolescents perceived themselves to be. Adolescents disclosed more to mothers than to fathers, particularly regarding personal issues, but mothers overestimated girls' disclosure. Greater trust, perceived obligations to disclose, and, for personal issues, more parental acceptance and psychological control predicted more disclosure and less secrecy.     

Rediscovering an American Legacy of Service through a Free Curriculum

Abstract

This case study highlights a free curriculum created to commemorate the World War I centennial and to celebrate the future of volunteerism and global citizenship education by encouraging students to engage in local, regional, and international service. The lesson plans are aligned with Common Core and UNESCO Global Learning standards, and use primary sources to highlight the little-known efforts of Americans who volunteered in nonmilitary roles before and after the period of American neutrality. The curriculum was a result, in part, of newly accessible collections from the Archives of the American Field Service and AFS Intercultural Programs and related outreach efforts.     

Possibilities for MOOCs in Corporate Training and Development

The term MOOC, an acronym for massive open online course, has been nearly ubiquitous in recent discussions about online education and distance learning. Some articles have questioned the MOOC's tentative role as “the future of education,” while others have framed it as a disrupter of traditional higher education. Research in earlier years trended toward the ways in which MOOCs may be changing the landscape of higher education. However, in the past two years, greater consideration has been focused on how MOOCs may play a role in the corporate world. The year 2012 may have been deemed “The Year of the MOOC,” but many saw 2014 as “The Year of the Corporate MOOC.” Despite MOOCs reaching their prominence as disrupters of traditional higher education, MOOC providers are now aggressively pursuing opportunities in the corporate sector. This presents a great opportunity for corporations to drive this relatively new learning platform and to tailor it to meet their organizational needs. The potential uses for MOOCs in the corporate world are vast. MOOCs can expand corporate training options, offer new recruiting techniques, and provide innovative marketing and branding channels. This article identifies the features of MOOCs, briefly reviews the history of the MOOC movement from academic MOOCs to corporate MOOCs, and discusses the possibilities for extending the MOOC format to a corporate training and employee development environment.
