基于多元回归模型分析的旅游者风险感知影响因素评价研究

旅游产业的高关联性和高敏感性使得旅游危机几乎无处不在,旅游者对旅游目的地的风险感知将在一定程度上决定其行为选择,有关旅游者风险感知的研究是旅游目的地危机管理的重要组成部分。影响旅游者风险感知的因素分为4大类22项,运用多元回归模型对其进行分析,可知对旅游者风险感影响较为显著的有危机发生地获得外部救援的能力、媒体对危机事件的客观报道、对危机事件相关知识的了解程度、危机发生地的相关恢复计划和措施、来自周围人的影响、性别、政府部门的态度及表现等10个方面。     

Effects of Multiple Exemplar Training on the Emergence of Derived Relations in Preschool Children Learning a Second Language

We evaluated the facilitative effects of multiple exemplar training (MET) on the establishment of derived tact relations in typically developing children. A multiple-probe design across stimulus sets was implemented to introduce MET. Participants were first taught to conditionally relate dictated names in English to their corresponding objects (listener behavior; A-B relations), followed by tests for derived tacts (B-A relations). If participants failed these tests, MET was implemented whereby tact relations were explicitly taught with novel stimulus sets, followed by test probes with the original training set. MET continued with novel stimuli until participants met criterion for the emergence of derived tact relations or after exposure to three MET sets. Results indicated failed tests for tact relations following direct training in listener relations, and marked improvements in derived tact relations following MET across all participants.     

Establishing Naming in Typically Developing Two-Year-Old Children as a Function of Multiple Exemplar Speaker and Listener Experiences

Naming is a verbal developmental capability and cusp that allows children to acquire listener and speaker functions without direct instruction (e.g., incidental learning of words for objects). We screened 19 typically developing 2- and 3-year-old children for the presence of Naming for 3-dimensional objects. All 9 3-year-olds had Naming, and 8 of 10 2-year-olds lacked Naming. For the 2-year-old children who lacked Naming, we used multiple-probe designs (2 groups of 4 children) to test the effect of multiple exemplar instruction (MEI) across speaker and listener responses on the emergence of Naming. Prior to the MEI, the children could not emit untaught listener or speaker responses following match-to-sample instruction with novel stimuli, during which they had heard the experimenter tact the stimuli. After MEI with a different set of novel stimuli, the children emitted listener and speaker responses when probed with the original stimuli, in the absence of any further instruction with those stimuli. Seven of 8 children acquired the speaker and listener responses of Naming at 83% to 100% accuracy. We discuss the basic and applied science implications.     

留学生与中国现代学科群的构建

在中国传统文化尤其是学术文化的现代转型过程中,现代学科群的构建起了关键的作用。而促进中国自然科学学科和人文社会科学学科建立的主力则是"五四"前后逐渐涌现的留学生新知识群体。这是留学生学贯中西、具有西学与中学双重文化因子的必然结果。考察留学生与中国现代学科的互动关系,可以从一个重要侧面去准确地把握中国文化现代化的进程。     

多元灵活与长效稳健:构建相对贫困治理长效机制的双重维度

脱贫攻坚战即将取得全面胜利,我国也即将进入后扶贫时代.面对后扶贫时代相对贫困治理的复杂局面,构建相对贫困治理长效机制应沿着多元灵活与长效稳健这两重雏度进行,这是由相对贫困两大相互关联的属性决定的.在构建相对贫困治理长效机制过程中,在分析两重维度分别具体如何建设之后,可以看到这两重维度之间也存在着张力与矛盾、联系与相互影响,可以得出应以正确的审视视角展开对这两个维度的有机统一,从而实现对相对贫困治理长效机制的整体构建的初步结论.沿着有机统一的双重维度展开建设的相对贫困治理长效机制,将依靠多元且专业化的扶贫责任机构、长效且权威的扶贫法律法规、专业性与党性并存的建设主体、深入且效果持久的精神扶贫举措等,应对将在相当长的历史时期内存在的、复杂变动的相对贫困状况.     

海上稠油热采井井筒温度场模型研究及应用

摘要：海上稠油油田的开发越来越受到人们的重视,多元热流体吞吐是一项集热采、烟道气驱等采油机理于一体的新型、高效稠油开采技术,该技术在渤海油田进行了现场试验并取得了成功。以渤海 M 油田多元热流体吞吐实验井为例,介绍了海上稠油油田多元热流体吞吐工艺的特点;研究了热流体吞吐井各传热环节及井筒温度场分布模型,建立了井筒综合传热系数的计算方法,并以海上实际热流体吞吐井为例进行了计算。在此基础上,模拟了隔热油管导热系数、下入深度、多元热流体组成等工艺参数对热采效果的影响,并得到了一些有益的结论,为海上稠油油田规模化热力采油工艺方案优化设计起到指导性作用。

The Multidimensional Measurement of Poverty in Belgium and Britain: A Categorical Approach

In recent years, both in socialscience and policy circles, there has been agrowing consensus on the multidimensionalnature of poverty. However, theoperationalisation of the concept has notfollowed this development, as most studies arestill primarily based on income. In thisarticle, we propose to measure the concept ofpoverty using both monetary and non-monetaryindicators. To this end, a latent classmeasurement model is used, allowing us to takeaccount of the multidimensionality of the dataand the discrete nature of most availablepoverty indicators. The proposed measurementinstrument allows for poverty to manifestitself in different ways or forms for differentsubgroups in the population. Furthermore, theoccurrence of multiple deprivation, rather thana `negative' score on only one indicator, istaken into account. In addition, specialattention is paid to the feasibility ofconstructing a multidimensional poverty measurewhich can be used to study poverty dynamicswith longitudinal panel data. We presentfigures on the size and the social distributionof the `poor' population in Belgium andBritain. These figures indicate that theresults of our multidimensional measurementprocedure are both plausible and substantivelyinterpretable.
