论资源型城市的可持续发展──以唐山市为例

唐山是我国最早建立起来的重要能源生产基地之一,大部分企业是依靠煤电而建立起来的。然而,随着煤炭资源的渐近枯竭,现有的能源逐渐不能满足社会经济不断增长的需要。资源、环境、产业结构诸因素与经济社会发展产生一系列矛盾,将对地区经济发展产生严重的影响。资源型城市应如何规避＂资源诅咒＂的风险,实现可持续发展至关重要。     

教育系统范式变革的研究与启示

随着信息社会的到来,工业社会中形成的学校教育范式越来越不能满足社会发展的需要。进行教育系统范式变革,建立适合信息社会的教育系统范式已成为教育研究者的跨世纪研究任务。教育系统范式变革研究领域的代表人物是巴纳锡、赖格卢斯和达菲,特别是赖格卢斯最近几年提出的变革的最新观点和思路,包括个性化教学、教学设计理论的系统重构和教学系统范式变革方案的设计与实施等理论,对肖今教育变革带来的启示是：教育改革是一个复杂系统,过度强调某一个因素的变革不利于改革的成功．     

Serial position effects in social transmission of food preference

The serial position effect in Long-Evans rats was evaluated in two experiments. In Experiment 1, the effect in a group for which an interstimulus interval (ISI) was introduced between items in a list of demonstrators was compared with that in a group without an ISI. With an ISI, a recency effect was produced. In Experiment 2, a serial position effect group was compared with four groups in which either the distinctiveness or the context of the middle item was changed, relative to the items on either side of it. A von Restorff effect was produced when a rat from a different strain was used as a demonstrator in Position 2. The results for Experiment 1 are discussed in relation to interstimulus effects in monkeys and those for Experiment 2 with respect to changes in the physical properties of middle items.

The relationship between reviewer judgments and motion picture success: re-analysis and extension

The relationship between the judgments of professional reviewers and the economic success of cultural products, such as motion pictures, has been the topic of controversial debates involving both scholars and industry experts. This study builds on previous research that distinguishes an ??influencer effect?? of reviews from a ??predictor effect.?? By empirically separating consumers?? and reviewers?? perceptions of movie quality through an auxiliary regression approach (and thus effectively controls for consumers?? quality perceptions), this study advances the discussion by investigating whether and how isolated reviewer quality perceptions are associated with box office results. The authors empirically test a non-linear effect of reviewers?? quality perceptions on box office returns, including a comprehensive investigation of the moderating forces of this relationship, using regression and simple slope analyses. Data from all 1,370 narrative films released in the United States between 1998 and 2006 reveal that though the short-term box office generally is not influenced by isolated reviewer quality perceptions, a non-linear relationship exists between reviews and long-term box office returns, such that films rated highly by reviewers are more strongly influenced than those that are not. In terms of moderators, the authors find evidence for several arthouse and mainstream characteristics to moderate the relationship between isolated reviewer quality perceptions and box office results.     

读者信用积分制度若干问题研究

读者信用积分制度是把信用积分理念引入到图书馆工作服务中,利用信用制度的独特作用来弥补现行制度的不足。读者信用积分制度在前提条件、特点、运行流程等方面有其独特之处;外在因素对读者行为和图书馆均存在着一定影响,是进行积分评估时需要考虑的因素;通过对传导效应、磁性效应、失信曲线、补救机制、读者信用等级表等内容的探讨有助于深入理解读者信用积分制度。推广读者信用积分制度,对于规范读者行为,提升图书馆服务具有重要价值。     

调查与调研在IC/LC评估与评价中的应用

评估与评价信息或学习共享空间(Information/Learning Commons,简称IC/LC),不仅对管理者和用户明确建设目标、评判IC的价值或效果、衡量满意度、保证IC良性运行,提高IC服务水平等有着重要意义,而且为管理者、投资人及监督、考评部门实施有效管理以适应时代变革提供科学依据,它贯穿IC(LC)规划与运营的整个过程,是IC规划与实施中最为重要的一环。IC的评估与评价需要科学的调查与调研。该文探讨了调查与调研在IC评估与评价中的应用问题,认为调查与调研对于评估与评价IC规划与实施有着重要的指导意义。
