几种烟用香精香料的微囊化及其在烟草中的应用研究

选用β-环糊精做为囊材,掌握烟用香精β-苯乙醇、异戊酸及香叶油作为包埋对象,控制不同的包埋条件获得目标微胶囊．通过红外分析和热重分析测定包埋及释放情况,并对添加微胶囊的样品卷烟给出感官方面的品吸评价,结果显示：β-环糊精对3种烟用香精均有一定的包埋作用,对于液体香精固体化,防止香精物质的挥发起到了一定的功效．

基于统计分析下的西藏职业教育发展趋势与对策研究

应用数学原理和模型,运用统计软件DPS,以近23年来西藏职业教育各项指标为原始数据,研究各个自变量间的相关性,建立各个自变量对因变量的多元线性回归模型,利用趋势预测模型预测2008年的各个指标的值,最后利用趋势外推预测所得的预测值套用线性回归模型再次预测2008年西藏每万人口中的频数.得出结论:两种模型对2008年每万人口中频数的预测值82.9203和83.3333非常接近,反映了所选用和建立的数学模型在理论上具有合理性和有效性.

Options for Change: A Flexible Vehicle for Curriculum Evolution and Reform

In this article we examine a flexible curricular approach known as the “Option.” The Option enables students to supplement traditional majors with a coherent set of courses and other educational experiences in a related, often interdisciplinary field. Options can act as curricular bridges between mainstream academic fields and problems of professional practice. They can also give students experience with emerging subject areas (e.g., biomedical engineering). Options serve as laboratories for experimenting with new subject areas before incorporating them fully into the curriculum as majors and minors. Hence, Options promote creativity and risk-taking by providing a proving ground for potential new academic programs.Roger G. Baldwin received his doctorate in higher education from the University of Michigan. He is currently Professor of Higher, Adult, and Lifelong Education at Michigan State University. His research interests include curriculum development and reform, faculty career development, and organizational change. Melissa J. Baumann received her doctorate in Materials Science and Engineering from Case Western Reserve University. She is currently Associate Professor of Engineering at Michigan State University. Her research interests include biomedical materials research, specifically ceramic scaffolds in bone tissue engineering and biomedical engineering education.     

Environmental art as an innovative medium for environmental education in Biosphere Reserves

A key goal of Biosphere Reserves (BR) is to foster environmental education for sustainable development. In this study we systematically analyse two cases in which environmental art is used as a mechanism to engage communities in ‘building environmental understanding’, in Noosa BR in Australia and North Devon BR in the United Kingdom. Data were derived through document analyses, site visits, questionnaires and semi-structured interviews conducted with the audience, artists, and residents. The study concludes that environmental art can build understanding through (1) exchanging ideas and providing dialogue (2) building a sense of place (3) clarifying and enhancing the understanding of information and issues, and (4) generating concern. Consequently environmental art should be considered an innovative addition to the suite of environmental education tools used in other BRs and community organisations that aim to educate about the environment.     

The Ontogeny of Social Information Gathering

When facing the unknown, humans tend to consult others for guidance. This propensity to treat others as information sources has wide-ranging implications, being in part responsible for the breadth and depth of our world knowledge. As yet, little is known concerning when and how young children acquire this important skill. Social referencing and communicative abilities in infancy have been interpreted by many as reflecting precocious social information-seeking ability, but the evidence is far from compelling and equally compatible with an attachment regulation interpretation. While the evidence indicates that infants as young as 12 months are good consumers of social information, it falls well short of demonstrating that they are active seekers of that information. Moreover, genuine social information seeking requires an implicit conception of the knowledge-ignorance distinction, and existing research on children's theories of mind suggests that such a conception is most likely not available in infancy. For these reasons, we argue for a developmental account of social information-gathering ability, one that is consistent with the larger body of evidence concerning sociocognitive abilities in infants and young children.     

高师大学生心理健康水平与社会支持的相关研究

目的：了解高师大学生心理健康水平与社会支持的关系。方法：采用SCL—90、社会支持量表对陇东学院788名师范专业大学生进行测查、结果：高师大学生在心理问题的表现、获得社会支持的程度方面存在显著的性别差异?获得高社会支持的高师大学生心理健康水平也高；获得低社会支持的高师大学生心理健康水平也相应较低、结论：高师大学生心理健康水平与其所获得的社会支持之间存在着显著的相关关系。
