科学与人文融合视角下素质教育的境界研究

科学教育和人文教育的融合是素质教育的核心内容,也是高等教育改革和发展的趋势.其融合的境界可分为由低到高的三个层次:科学知识与人文知识的融合,科学精神与人文精神的融合,科学行为与人文行为的融合.融合的进程遵循辩证唯物主义认识论的规律,具有递进性和回复性的特点.     

上海郊区发展历史、现状及展望

我国城市郊区建制效仿苏联,初期目的是保障大城市居民的鲜活农产品供应.20世纪90年代以后,上海在城乡规划和政策导向两方面积极促进郊区工业化与城镇化的结合,促进大规模商业服务项目落户郊区,一批兼具就业、商务、交通、居住和休闲娱乐等功能的新城和新市镇随之发展起来.随着上海国际经济、金融、贸易和航运中心的逐步建成,郊区作为上海先进制造业基地、城市发展的未来空间、现代服务业延伸地区、鲜活农副产品生产基地,以及市民休闲度假基地的重要地位将进一步显现出来,郊区将继续成为上海发展最有活力的地区.     

城市土地价格效应对城市土地集约利用的影响机理研究

一、引言作为一种经济景观．城市是社会经济活动空间集聚的结果．是空间经济体系格局的最高表现．是一定地域中各种市场力量相互交织在一起并大规模集中的必然结果。因此．城市经济的本质特征就在于其空间集聚性。集聚经济的存在,促使各种生产和生活活动在城市集聚．最终导致城市土地供不应求．城市土地价格上涨。为了继续获取集聚经济所带来的成本节约等效益．     

交易费用、农地流转与新一轮农地制度改革——基于苏、桂、鄂、黑四省区农户调查数据的分析

农地流转是促进农地规模经营的必经之路,已成为新一轮农地制度改革的中心议题。基于江苏、广西、湖北及黑龙江四省区农户调查数据的实证分析结果显示,交易费用是影响农地流转的一个重要约束因素,农地流转中存在的交易费用既抑制转入户转入土地,又抑制转出户转出土地。因此,新一轮农地制度改革进程中应全面降低农地流转面临的各类交易费用,促进农地经营权规范有序流转,发展农业适度规模经营。     

Trajectory of problem behaviours of Korean adopted children: using piecewise hierarchical linear growth modelling

This study examined the trajectory of problem behaviours in domestically adopted children in South Korea as they aged. This study used the Panel Study on Korean Adopted Children's longitudinal, three‐wave data (2006, 2008 and 2010). Although data were collected at three time points, our data consisted of six time points, which covered the 5–10 years age range of the adopted children at the time of survey. One hundred sixty‐four children were included in the analysis, 75 of whom contributed to one time point, 74 to two time points and 15 to three time points. The trajectory of the problem behaviours of adopted children was examined using a piecewise hierarchical linear growth model. Because the initial exploration of the data suggested non‐linear changes in behaviour problems over time, we split the growth trajectory into two time periods: Time 1 (5–7 years) and Time 2 (7–10 years). A two‐rate model was used to estimate separate slopes for the two time periods. Results showed that the externalizing and internalizing problems of adopted children have different trajectories. Internalizing problems did not show significant changes after 5 years of age, while externalizing problems increased until 7 years of age and decreased significantly thereafter.     

An optimal online algorithm for the parallel-batch scheduling with job processing time compatibilities

We consider the online (over time) scheduling on a single unbounded parallel-batch machine with job processing time compatibilities to minimize makespan. In the problem, a constant \(\alpha >0\) is given in advance. Each job \(J_{j}\) has a normal processing time \(p_j\). Two jobs \(J_i\) and \(J_j\) are compatible if \(\max \{p_i, p_j\} \le (1+\alpha )\cdot \min \{p_i, p_j\}\). In the problem, mutually compatible jobs can form a batch being processed on the machine. The processing time of a batch is equal to the maximum normal processing time of the jobs in this batch. For this problem, we provide an optimal online algorithm with a competitive ratio of \(1+\beta _\alpha \), where \(\beta _\alpha \) is the positive root of the equation \((1+\alpha )x^{2}+\alpha x=1+\alpha \).     

Threatened plant species in the river ports of Central Europe: a potential for nature conservation

Industrialized areas represent a special group of urbanized areas, but sufficient attention has not been given to them concerning plant species richness and its importance for biodiversity conservation. These sites are considered the main drivers of biological invasions and biotic homogenization on a global scale, but the question of how and to what degree they contribute to biodiversity has yet to be raised. Data for 62 river ports (16 German, 26 Czech, 7 Hungarian, 4 Slovak, and 9 Austrian) on two important Central European waterways (the Elbe-Vltava and Danube waterways) were gathered for 40 years. In total, 1 240 plant species were found. Of these, 371 were classified as threatened and protected, nearly one third of the total number of species found in all of the studied Elbe, Vltava, and Danube ports. Significant differences in the proportion of threatened species in ports and cities were not found. More threatened species were found in the Danube ports than in the other ports, but their numbers fluctuated depending on the size of the port and the region (country). The results showed that the ports must be regarded as special types of species-rich industrial areas; thus, they should not be considered to be only sources of spreading invasive alien species. When planning port development, uniformity and vegetation management that is too intensive should be avoided. Extensively managed open areas and habitat diversity should be maintained.

     

Compare Chinese with Americans: how trait comparisons shape public perception of Sino–US relationship and China policy issues

This study draws on social comparison theory and the spread activation literature to explore the effects of opinions about the personal traits of Chinese and Americans on the United States (US) public’s perceptions of the Sino–US relationship. The study also explores how perceptions of the Sino–US relationship predict the perceived importance of various Chinese policy issues. The analyses of the secondary survey data showed that comparisons of positive and negative traits had different effects on public opinion about the Sino–US relationship. The respondents who viewed China as a partner or as a competitor also thought that human rights, the freedom of Tibet, and economic issues were important. Those who viewed China as an enemy believed that the selling of arms to Taiwan was important. The implications of the findings for theory construction and national image campaigns are discussed.     

试论政府信息主动公开行为的司法审查

我国《政府信息公开条例》突出了主动公开在信息公开领域的积极作用,强调了政府主动公开信息的原则。但现实表明,我国政府信息并未真正处于阳光之下,有必要借鉴国外有关主动公开政府信息的有益经验,结合我国实情,完善我国政府信息主动公开制度,以望早日实现政府信息公开的价值目标,实现＂阳光政府＂建设。
