Reengineering Academic Teams Toward a Network Organizational Structure*

This article examines student teamwork in the academic field from a structural perspective. Student teams are often prearranged and then left to organize themselves and get on with their work, without any further structural support; this, however, can become a negative experience on teamwork. A varied contribution among team members often occurs and unavoidably leads to friction and reduced performance. The aim of this project is to explore the main problems in academic teamwork and investigate tools that provide relevant solutions. We present the concept of network organizational structure and discuss how this can improve collaboration and communication. The main tools to achieve a structural transformation from the more traditional form of team organization to the fairer network form, and their implications are discussed.     

话语标记“还好1”和“还好2”的功能用法与联系

“还好”演变为话语标记主要有两条路径,其演变过程具有不同的功能用法,但“还好1”和“还好2”最终成为话语标记时都保留着“降格的优势评价”和“侥幸”义。话语标记“还好”主要呈现独立使用的形式,不会置于句子成分内,在使用中,仍保留一定的主观性特点,并主要起连接作用。

Selecting Path Models in SEM: A Comparison of Model Selection Criteria

Model comparison is one useful approach in applications of structural equation modeling. Akaike’s information criterion (AIC) and the Bayesian information criterion (BIC) are commonly used for selecting an optimal model from the alternatives. We conducted a comprehensive evaluation of various model selection criteria, including AIC, BIC, and their extensions, in selecting an optimal path model under a wide range of conditions over different compositions of candidate set, distinct values of misspecified parameters, and diverse sample sizes. The chance of selecting an optimal model rose as the values of misspecified parameters and sample sizes increased. The relative performance of AIC and BIC type criteria depended on the magnitudes of the parameter misspecified. The BIC family in general outperformed AIC counterparts unless under small values of omitted parameters and sample sizes, where AIC performed better. Scaled unit information prior BIC (SPBIC) and Haughton's BIC (HBIC) demonstrated the highest accuracy ratios across most of the conditions investigated in this simulation.

Ethics in classroom assessment practices: Issues and attitudes

Student evaluations should “be ethical, fair, useful, feasible, and accurate” [JCSEE (2003). The student evaluation standards. Arlen Gullickson, Chair. Thousand Oaks, CA: Corwin]. This study focuses on defining ethical behavior and examining educators’ ethical judgments in relation to assessment. It describes the results from a web-based survey of educators in which they read a brief scenario and indicated whether the student evaluation practice in the depiction was ethical or unethical. Results showed strong agreement among the educators on fewer than half of the scenarios presented in this study. These findings suggest that assessment is currently an educational realm without professional consensus.

薄皮甜瓜对南方根结线虫的综合抗性评价

目的:研究南方根结线虫对薄皮甜瓜幼苗生长、发病指数的影响,对6种不同品种薄皮甜瓜的综合抗性作出评价。方法:采用6个不同品种的薄皮甜瓜为实验材料,采取盆栽人工接种方式,通过对甜瓜幼苗的植株鲜重、根瘤数、根结指数、卵粒指数、病情指数、根系电导率、根系MDA含量进行测定,并利用隶属函数对此进行综合分析。结果:接种南方根结线虫45 d后,不同品种的甜瓜幼苗长势、发病指数等差异较大。结论:地方栽培的常规品种中,‘九道沟’与‘羊角酥’甜瓜对南方根结线虫的抗性较强,‘绿宝石’、‘苹果酥’以及‘海南3号’甜瓜对南方根结线虫抗性居中,‘甜宝’甜瓜对南方根结线虫的抗性最差。     

外国文学教学中的道德建设

教育和道德的关系是一个长久的伦理命题。从建国之初,关于教育和塑造新型的社会主义道德问题就以科学的方式得到重视。科学的方式就意味着在建立社会主义性质的大学的过程中,创建新式的学科,使社会主义意识形态成为基本的价值规范。外国文学的教学可以在世界文学的背景下,通过文学规范的变革显示文学规范的选择与历史正义性的逻辑关联,以及社会主义合法性的审美化论证。而所有的知识和知识规范的建立都可以帮助学生形成道德自觉。
