Teaching Sacred Texts in the Classroom: The Pedagogy of Transmission and the Pedagogy of Interpretive Facilitation

Empirical research in Jewish education has found almost exclusive use of transmission pedagogy among Jewish studies teachers. This study hoped to fill out the empirical landscape by studying Jewish studies teachers who prioritize student-driven interpretation. It followed six Jewish studies teachers in four different Jewish elementary schools who all professed a commitment to student-driven textual interpretation. It found that in such classrooms there was a clear pattern of teaching moves. This article offers a detailed portrait of the previously undocumented Jewish studies pedagogy, interpretive facilitation.     

Si3N4陶瓷二次部分瞬间液相连接数值模拟

利用热弹塑性有限元方法，通过瞬态热结构直接耦合，模拟Si3N4陶瓷二次部分瞬问液相连接过程，分析了连接接头残余应力分布状态和中间层对此连接接头应力分布的影响。结果表明：陶瓷外表面靠近连接界面的附近存在最大拉伸应力；采用Ti／Cu／Ni／Cu／Ti中间过渡层的接头应力出现大幅度的降低；陶瓷与金属之间热膨胀系数的巨大差异是导致残余应力的主要原因，采用中间过渡层能缓和接头的残余应力，提高接头强度。     

Comparing Student Performance and Growth in 2- and 4-Year Institutions

This study examines the organizational characteristics of 51 higher education institutions in relationship to student performance and growth. The study first finds that organizational measures of mission, size, wealth, complexity, and selectivity are statistically represented by the 2-year versus 4-year college mission. Findings indicate that 2-year and 4-year campuses indeed do exert significantly different influences on undergraduate GPA and self-reported intellectual growth. Next, the study uses both OLS regression and HLM to examine these influences. High school percentile rank and college classroom experiences are better predictors of Cum GPA at 4-year institutions, while student effort is a better predictor of GPA at 2-year institutions. Whereas the most important predictors of Cum GPA include precollege measures such as high school percentile rank and SAT score, the most influential predictors of student intellectual growth are campus experiences including classroom vitality, peer support, student effort, commitment, and involvement. Controlling for all other variables, students at 2-year institutions receive higher grades, and students at 4-year campuses experience more growth.     

基于Bookmetrix的G20国家图书影响力比较研究

[目的/意义]对比分析G20国家图书影响力的现状，为我国提升图书国际影响力提供借鉴。[方法/过程]选择Springer收录的5个学科（化学、工程、医学、法律、历史）图书为样本，以Bookmetrix为数据源，在讨论指标覆盖率与相关性的基础上，从图书的产出数量、5类指标（下载量、引用量、提及量、读者量及评论量）以及合著关系3个方面展开比较分析。[结果/结论]研究发现：1）在指标覆盖率和相关性方面，整体情况与中、美、德等国家层面的表现类似。体现为图书的下载量覆盖率最高，读者量和引用量相关性值较高且稳定。2）中国的国际图书产出量与德国、美国、英国存在较大差距，但在指标均值、综合排名方面表现良好。3）在G20国家图书合著网络中，人文社科类图书国际合作强度明显低于理工类学科；美国、德国具有较高的科研合作实力与影响力；中国的国际合作具有一定基础，但整体影响力作用并不突出。     

中国愿油定价机制改革的实证检验与思考——基于大庆原油的分析

我国的原油定价机制尚缺乏研究。回归检验了Minas原油至我国大庆原油的价格传导关系．讨论了大庆原油价格的形成特点，并归纳出国内外油价波动传导路径。尽管原油价格之间具有长期一致性．但背离指标揭示了Minas原油价格具有异常波动频繁而剧烈的短期特征．这种蕴舍风险的价格变化同样反映在大庆原油的价格上。进而分析了油价波动对经济运行的不利影响．提出了改进我国原油定价机制的建议。     

基于J2EE平台的分布式运销系统分析与设计

当前许多企业都在异地建立分支机构，它们负责其所在地的各种业务活动，这就不可避免地产生了总部和分支机构之间的信息共享和交互问题。那么如何实现分布于广阔地理范围的分支机构与总部的信息集成就成为企业信息化道路上迫切需要解决的问题之一。本文以我们自行设计和开发的准噶尔能源公司运销管理系统为例来介绍基于J2EE架构的分布式信息系统的分析与设计。

Commercialization of patents and external financing during the R&D phase

Using a unique database on Swedish patents owned by small firms and individuals, survival models estimate how different factors influence the decision to commercialize the patents. Such an analysis has seemingly never previously been undertaken. Since the owners know more about the patents than potential external financiers, problems related to asymmetrical information are present. To overcome these problems when inventors and small technology-based firms need financing, Sweden has for a long time relied on government support rather than private venture capital firms. The empirical results show that the larger is the share of patent-owners’ costs covered by government financial support during the R&D phase, the lower is the probability of patents being commercialized. This lower degree of commercialization is likely to depend on (1) the soft terms of the government loans, where the patent owner can avoid paying back the loan if the patent is never commercialized and/or (2) that the government is not able to select promising projects. The first explanation is related to moral hazard and the second one to adverse selection. The policy suggestion is for government to change the design of the loans, to base them on firms rather than projects.
