略论“两制”并存视野下中美对外政策的不同选择——《当代世界经济与政治》课程中美对外政策问题断想

面对二战后世界主题转换,世界格局变化,经济全球化发展不平衡不断加剧的形势,中国推进“两制”的关系的理论创新和发展,而美国从其国家利益和全球战略出发,在“两制”关系上,死抱冷战思维,并利用一切手段、一切可能钳制和牵制中国,无视多样性和差异性,继续以社会制度和意识形态划线,强制推行美国所谓的民主、价值观和实用标准。

基于应用型本科人才培养的离散数学教学改革探讨

《离散数学》作为信息管理与信息系统专业核心课程之一,由于概念多、理论性强且抽象,教学时容易造成知识点散、教师满堂灌的局面,使学生学习时感到吃力,从而失去对课程学习的兴趣。文章从信息管理与信息系统专业应用型人才培养的角度,对离散数学进行教学改革,广泛全面地增加应用案例,使学生在学习后能应用所学理论解决一定的实际问题。     

从易经逻辑到数理辩证逻辑

早在6000多年前,中国先人就创造了以爻卦为命题形式,以八卦和六十四卦为体系的辩证逻辑形式演绎系统。此后,又给出了爻辞和卦辞的语义解释系统。后来,又给出了《易经》的语义和语用解释系统。它自古至今,长盛不衰,成为中国的传统逻辑、文化发展的活水源头。以互补结构整体思想的形式结构和推理有效式规律为研究对象的数理辩证逻辑,是以易经逻辑为其辩证逻辑基础的,它又是易经逻辑的一致性扩大系统。它为实现易经逻辑的现代化发展提供了现代逻辑形式化方法。易经逻辑形式公理系统DPA 就是其现代化形式公理系统。

The Impact of Coordination Methods on the Enhancement of Business Writing

Universities with limited resources are being pressured to cover more material within their degree programs. Because of this, schools are looking to integrate material from different classes. This paper sets out to determine if students can learn business writing within the context of another class, specifically, an information systems class. The goal is to eliminate the need for a separate business‐writing course. However, the students will have to learn the material with limited support in order not to place an additional load on the instructor. This study investigates whether individuals can develop their business‐writing skills during the course of repeated group work and whether there are differences in the level of their learning, based on collaborative media. The results show that individuals can learn business‐writing skills with a minimum of support through direct instruction. In addition, there is no difference between individuals working in face‐to‐face (F2F) groups and those working in groups using electronic collaborative work (ECW) systems.

Measuring Student Perceptions of Blackboard Using the Technology Acceptance Model

Web Enhanced Instruction (WEI) is not intended to replace the traditional classroom setting, but rather to supplement the traditional lecture with course content that can be accessed from campus or the Internet. WEI has the potential to extend the boundaries of traditional classrooms by providing new opportunities for communication and interaction between students and the instructor. While the potential benefits of augmenting the traditional class with WEI have been recognized and discussed, what has remained largely unknown are student reactions to WEI as an addition to the traditional lecture. The Technology Acceptance Model (TAM) has been widely used in the Information Systems research to gather user reactions to information systems. The TAM examines users' perceptions of Usage, Usefulness, and Ease of Use. This research applied the TAM to the academic setting to measure student reactions to Blackboard, the WEI tool used in this study. Using several multivariate methods, results suggest that students (n = 692) found that the Blackboard elements which are associated with Course Content (Course Documents, Lectures, Student Tools, Announcements, and Quizzes) are used more often and are seen as more useful than those items that provide Course Support and communication (Discussion Board, External Web Sites, Faculty Information, and E‐Mail).     

Research capacity for local innovation: the case of conservation agriculture in Ethiopia,Malawi and Mozambique

Purpose: The limited uptake of improved agricultural practices in Africa raise questions on the functionality of current agricultural research systems. Our purpose is to explore the capacity for local innovation within the research systems of Ethiopia, Malawi and Mozambique.

Design/methodology/approach: Using Conservation Agriculture (CA) as a case study, we qualitatively explore with 26 locally based agricultural researchers the context of CA research and promotion, including their perceptions on persistent research gaps and issues in closing them.

Findings: Respondents identified that CA was not yet a finished product, with concerns regarding the benefit, feasibility and relevance of CA implementation. They asserted that while further adaptation was required, they were unable to do this due to institutional constraints within their research, extension and policy contexts.

Practical implications: We find that CA continues to be considered a donor-driven intervention in its current form and requires substantial further adaptation to local contexts before researchers will deem it ready for farmer uptake. The five research gaps identified by respondents highlight practical areas where further adaptations must occur.

Theoretical implications: Our findings suggest a lack of participatory research and extension most likely reflects limited financial, human and social capital to implement more participatory approaches. Without addressing these capacities, widespread adoption of complex farming systems change appears unlikely.

Originality/Value: Whilst many studies have identified a need for local innovation to enable CA utilisation, few have qualitatively explored directly with local researchers the capacity of such systems to do so. We address this gap in the literature.
