The ultimate bending moment and maximal shear stress of a bulk carrier with two structural forms (single hull and double hull/ are calculated separately by using the combined moment which is determined by stochastic process. Then the assessment of reliability is carried out. The results indicate that by introducing the double-hull structure, the shear stress of side can be decreased to half of that of the primary structure( 50.7% i. but the effect on longitudinal strength is not obvious. Finally, the effects of different double-side skin widths on ultimate bending moment and the maximal shear stress are investigated, followed by proposals of the selection of the double-side skin width.  相似文献

Five suburban community colleges in a metropolitan area collaborated on a survey to parents of high school graduates of the class of 2002 who attended the colleges in fall 2002. The study was undertaken to learn more about parents roles in their students selection of community colleges, to give insights and information about this important community college constituency, and to assist community colleges to shape more effective ways to foster positive and supportive opinions among parents of potential students. Parents want the community college to provide students with credits and grade point averages enabling transfer, overestimate their students academic skills as measured by course placement tests, engaged in a number of college-choice activities, and indicate that factors associated with lifestyle and money were major reasons for selecting the community college. Associations between parents social capital and perceptions of their students academic abilities were found for a number of dependent variables examined. The study also revealed important differences in how participating institutions record and calculate key measures such as credits earned and grade point averages.  相似文献

社会主义市场经济是一种崭新的经济体制,它既具有一般市场经济的运行样式和道德倾向,又具有自己独特的内容和个性。因此,社会主义市场经济的道德理性精神不仅包括一般市场经济的道德原则,而且蕴含着社会主义的价值承诺和道德理想,这既是社会主义市场经济的应有之义,也是社会主义市场经济发展的现实要求。  相似文献

The influence of recent social and economicchanges in the Israeli kibbutz on the prolongedstage of youth was examined with respect tohigher education. The young people on thekibbutz of the late 1990s appear lessmoratorial and more instrumental about theirfuture and commence higher education earlierthan in previous age cohorts. When starting tostudy, their educational and professionalprospects are crystalized as those of thenon-kibbutz student. Most of them opt foracademic, degree-granting studies, but a higherpercentage than among the general populationprefer vocation-oriented colleges to theresearch oriented universities. In choosingfields of study, they prefer more appliedstudies like engineering, social services andpractical arts and are less likely to choosesciences and the humanities. De-communalizationand economic instability of the kibbutz,inadequate preparation in kibbutz high schoolsfor the competitive admission to theuniversities, exposure to a restricted range ofoccupations during adolescence, and lack of acultural tradition supportive of elitiststudies may explain this practical mood, moresalient among kibbutz women.  相似文献

长期以来,借鉴或采用西方教师教育研究的理念、经验和做法,已成为我国教师教育研究的基本范式,“文化殖民”现象普遍存在。由此,不仅造成基本国情、民族传统文化、本土教育资源等的“集体遗忘”,还造成研究者在价值选择上思维方式的单一、认识的片面、多元思想的消解。从后殖民主义、本土知识等的研究来看,我国教师教育研究必须要有“主体重建”,克服“民族化”或“西方化”二元对立的思维观念,强调“文化自觉”,摆脱文化帝国主义的束缚,走出一条中国的教师教育研究之路。  相似文献

INTRODUCTION Because of its low molecular weight and ability to fluoresce independently (George, 1997), the new molecular tag, green fluorescent protein (GFP), has become more and more popular after Prasher et al.(1992) cloned its cDNA in 1992. There are many reports describing the co-expression of GFP and a specific antibody or cytokine gene, with the fusion protein expressing the fluorescent activity and bio-logical activity of the complement protein (Haraguchi et al., 1999; Mclean…  相似文献
