ABSTRACTBoth Children’s services and Young Adult (YA) services have been recognized as essential in Japanese public libraries. This article reports on the present status of Children’s services and YA services in Japanese public libraries, based on the results of several investigations. These studies show that children’s services in Japanese public libraries already are generally popular. On the other hand, this article indicates that YA services in Japanese public libraries are gradually improving, due to the national recognition of the importance of YA library services. Examples of good practices in Children’s and YA services in Japanese public libraries are described and analyzed to identify the common themes that flow through these innovations. This article concludes with observations about the future involving library services for children and YAs, from the viewpoints of face-to-face traditional services and indirect services through their official websites. 相似文献

1789年至1794年的大革命对于法国政治和经济的发展来说都是重要的分水岭。它摧毁了旧制度,确立了以自由经济为基础的新经济秩序。然而大革命并没有改变法国经济的前工业化的性质,反而进一步加强了小农所有制,滋生了单子个人主义的价值观念,给法国工业化带来了极为不利的影响。 相似文献

ABSTRACTGrowth of their college's off-campus and online course offerings led librarians at SUNY Oswego to run usability tests with off-campus students to compensate for a lack of responses from this population during earlier usability testing. Constraints on testing with off-campus students included lack of funding and librarian time, as well as difficulty in attracting student participation. A brief usability study that could be completed by students in the first 10 minutes of class was devised, consisting of a first click test, a survey question, and a top task analysis activity. The study was conducted with 22 students from a satellite-campus Master's in Education program. Discussion includes selecting appropriate tests, analysis of study results, and application of data for improving Website design and information literacy instruction in an academic library. 相似文献

We conducted a series of experiments to investigate the extent to which prompting the construction of a force diagram affects student solutions to simple mechanics problems. A total of 891 university introductory physics students were given typical force and motion problems under one of the two conditions: when a force diagram was or was not prompted as part of the solution. Results indicated that students who were prompted to draw the force diagram were less likely to obtain a correct solution than those who were not prompted to solve the problem in any particular way. Analysis of the solution methods revealed that those students prompted to use a diagram tended to use the formally taught problem‐solving method, and those students not prompted to draw a force diagram tended to use more intuitive methods. Students who were prompted to draw diagrams were also more likely to depict incorrect forces. These results may be explained by two factors. First, novice students may simply be more effective using intuitive, situational reasoning than using new formal methods. Second, prompting the construction of a force diagram may be misinterpreted by the student as a separate task, unrelated to solving the problem. For instruction, the results of this study imply that ignoring students’ prior abilities to solve problems and their necessary developmental stages in learning formal problem‐solving techniques may lead to serious mismatches in what is taught and what is intended to be learned. 相似文献

为了考察过度投资和自由现金流的关系,对过度投资和自由现金流进行以会计资料为基础的量化,使得过度投资与自由现金流能够可以根据会计报表的数据推算,结合5030个中国A股上市公司2000-2006年的样本统计数据,验证Jensen的自由现金流量假说,并从成长机会、上市公司过度投资的计量和上市公司“过度投资”与自由现金流的敏感性三个方面进行了稳健性检验.实证研究表明,自由现金流为正的公司确实更容易发生过度投资行为,过度投资程度与自由现金流量水平正相关. 相似文献

This article focuses on the conceptualization and implementation of a web archiving pilot project of selected Russian and East European lesbian, gay, bisexual, and transgender (LGBT) websites by the University of California, Berkeley. It introduces the use of the Web Archiving Services (WAS) platform developed by the California Digital Library. While identifying the criteria used to harvest these websites, the paper also describes various complexities associated with the viability of projects related to such complex social and political issues as the Russian and Eastern European LGBT rights movements. The article does not take an ideological stance with respect to legal issues, but rather strives to preserve information for academic research. 相似文献
