Examining the Enactment of Web GIS on Students' Geospatial Thinking and Reasoning and Tectonics Understandings

Geospatially enabled learning technologies may enhance Earth science learning by placing emphasis on geographic space, visualization, scale, representation, and geospatial thinking and reasoning (GTR) skills. This study examined if and how a series of Web geographic information system investigations that the researchers developed improved urban middle-school learners’ GTR skills and their understanding of tectonics concepts. Paired-sample t tests for analyses of tectonics content knowledge and GTR achievement measures revealed statistically significant gains from pretest to posttest (p <.001) with large effect sizes. The findings provide support that GTR related to tectonics can be learned with appropriately designed learning activities using Web-based geographic information systems.

An explorative study of shopper-based salient e-servicescape attributes: A Means-End Chain approach

This study aims to address the gaps inherent in existing studies by exploring the salient e-servicescape attributes. Employing the Means-End Chain (MEC) approach, empirical evidence was obtained through in-depth interviews with online shoppers using laddering technique to determine the most frequently mentioned attributes from four servicescape dimensions: (1) ambient; (2) design; (3) signs, symbols and artifacts; and (4) interaction. Accordingly, we laddered three levels of online shoppers’ responses from concrete to less concrete abstractions, i.e. attributes, benefits, and end-desirable beliefs. As a result, seven salient e-servicescape attributes were identified. Each of the four dimensions suggests the attributes’ linkage to benefits and end-desirable beliefs. Specifically, the study finds quality photograph, as the salient attribute of the ambient dimension, may set the point of initial attraction and move shoppers from understanding the product to linking the web site contents. In the design dimension, navigation bar, categorization, and simple arrangement are the salient attributes. Company logo represents the most salient attribute under the signs, symbols and artifacts dimension because it not only facilitates recognition and recall of prominent web sites, it also acts as the determinant of perceived risks. In the interaction dimension, although pricing information is the salient attribute that evokes happiness and confidence among online shoppers, it may dilute their perception on web site's success. Instead, confirmation mail can possibly act as a determinant to web site's success. By offering a finer granularity of information, our findings provide insights to online sellers on the salient attributes to consider in order to effectively promote their shopping web sites to create positive emotional response and buying behavior among the online shoppers.     

Expert group formation using facility location analysis

In this paper, we propose an optimization framework to retrieve an optimal group of experts to perform a multi-aspect task. While a diverse set of skills are needed to perform a multi-aspect task, the group of assigned experts should be able to collectively cover all these required skills. We consider three types of multi-aspect expert group formation problems and propose a unified framework to solve these problems accurately and efficiently. The first problem is concerned with finding the top k experts for a given task, while the required skills of the task are implicitly described. In the second problem, the required skills of the tasks are explicitly described using some keywords but each expert has a limited capacity to perform these tasks and therefore should be assigned to a limited number of them. Finally, the third problem is the combination of the first and the second problems. Our proposed optimization framework is based on the Facility Location Analysis which is a well known branch of the Operation Research. In our experiments, we compare the accuracy and efficiency of the proposed framework with the state-of-the-art approaches for the group formation problems. The experiment results show the effectiveness of our proposed methods in comparison with state-of-the-art approaches.     

黄河干流控制性梯级水库联合运行对下游水文情势的影响

为评价黄河干流控制性梯级水库联合运行对下游水文情势的改变程度,根据花园口水文站1949-2010年的日径流资料,在水文改变指标体系(IHA)的基础上,采用变异范围法(RVA),定量分析了不同梯级水库联合运行前后,黄河下游水文情势变化情况及改变程度。分析结果表明:①梯级水库联合运行后,黄河下游的水文情势发生了高度改变,且改变度随着水库联合运行数量的增加而增强;②刘家峡和三门峡二库运行阶段,水文情势改变度为68.92%;刘家峡、龙羊峡和三门峡三库运行阶段,改变度为73.21%;龙羊峡、刘家峡、三门峡和小浪底四库运行阶段,改变度为87%;③不同水库联合运行对黄河下游生态水文特征的影响差异较大,尤其是四库联合调度后,汛期流量剧减,低流量频繁出现,致使河道的生物量和多样性急剧下降,严重危害河流生态健康。     

略谈主题教学法在“建筑装饰设计”课程中的应用

本文以苏州工艺美术职业技术学院正在积极推行的主题教学法为参照点,尝试在建筑装饰工程技术专业的核心课程＂建筑装饰设计＂教学过程中重新设计课程内容,并对老师和学生提出新的要求。该教学法以一个确定的中心主题为核心展开,它培养的是学生设计思维方法,重视的是整个设计过程。其过程具有严密的逻辑性和导向性,有利于开发设计思维,培养学生的设计思维逻辑能力。     

大武术观指导下学校武术师资的培养路径探析——以广东省为例

运用文献资料、问卷调查、专家访谈、逻辑分析等研究方法,对广东省学校武术师资现状、培养路径进行研究。结果显示,当前广东省学校武术师资少、分布不均衡、素质不高、培训少,教师希望参加武术培训的愿望高。研究认为,发展大武术观指导下的学校武术,师资培养是关键,其路径应该是省教育主管部门成立武术继续教育中心开展师资培训、地方教育主管部门和学校支持教师参加武术培训、组织专家成立武术讲师团开展＂走基层＂武术进学校活动、学校与专家结对子定点指导培训师资、定期举办多层次多形式的武术活动和比赛等。
