基于粗糙集理论的Web挖掘模型

在电子商务网站的Web日志中，蕴含着大量有价值的信息，利用Web挖掘技术能够有效获取这些信息，这将有助于提高电子商务运营管理的经营决策，在Web挖掘研究过程中，结合Web日志具有的数据量大，不确定等特点，提出了一种基于粗集理论的最小决策模型，运用这一模型，通过对决策表进行知识简化，可以导出简化决策有，最后获得最小解，电子商务系统的决策人员就可以依据得到的最小解，为提供个性化服务进行决策，应用基于粗集理论的数据挖掘方法，对Web日志进行挖掘，已经成为当前研究的热点问题。     

非对称信息下零售商成本扰动时供应链协调机制

建立市场需求为线性需求,包含一个供应商和一个零售商的供应链模型,当零售商成本信息为非对称信息时,研究2种情形的非对称信息供应链协调机制:正常情形下非对称信息供应链协调机制和零售商成本发生扰动情形下非对称信息供应链协调机制.研究表明,当零售商成本扰动小于一个阈值时,供应链系统利用原生产计划可以保证系统稳定运行,说明原有的协调机制具有一定的鲁棒性;当零售商成本扰动大于一个阈值时,要对原来的计划进行调整.最后,通过数值分析研究了零售商成本扰动对订单数量、零售价格、批发价格以及供应链成员和系统期望利润的影响.     

Does Work Harm Academic Performance of Students? Evidence Using Propensity Score Matching

In this article we analyze the effects of student work on academic performance for college students. In order to reduce the endogeneity bias due to selection into treatment, we use propensity score matching technique. This approach allows us to estimate the effects of student work separately for different years of study, which is not possible when inside instruments are used to deal with endogeneity of student work. We find predominantly negative effects of student work for all measures of academic performance (GPA, exam attempts, exams passed, and likelihood of passing a year), although many of these are economically and statistically insignificant. We supplement existing studies that do not estimate separate treatment effects for different years of study by showing that work while in college harms study outcomes mostly in the first year of study—by passing smaller number of exams and thereby increasing the likelihood of failing a year. Our results are consistent with evidence on difficulty with adjusting to college studies of first-year students, who face many uncertainties that affect finding the optimal allocation of time between studies, work and leisure.     

Stories From Intercultural Education in Serbia: Teacher Leadership and Parent Participation

This article explores the potential of teacher leadership as a strategy to promote intercultural education by empowering parents and members of ethnic minority groups to participate in the life of the school. It links the idea of participation for social justice with the goals of intercultural education within the context of the APREME (Advancing Participation and Representation of Ethnic Minority Groups in Education) project, which is located within a wider program of research, development, and advocacy designed to promote inclusion and social cohesion in the western Balkans. The outcomes of this action-based stage of the program are presented in the form of vignettes that portray teachers’ projects designed to enable parents and community members to participate more fully in the life of the school. Conclusions are drawn about the relationship between teacher leadership and a transformative approach to the intercultural education.     

Didactic strategies in early science teaching

The purpose of the article is to show the results of empirical research on the prevailing teaching strategies for teaching contents of the subject environmental studies (specifically when dealing with natural content) in the first triennium of the nine‐year primary school in the Republic of Slovenia. The information was obtained through a survey of 141 teachers from 60 randomly selected primary schools in the Republic of Slovenia. We found that teachers use different teaching strategies as students gain knowledge through experience, participation in education, they express their opinion, views, solve simple problems and explore. Such notice shall then direct the transmissions to the transaction and transformation, which was an important objective of the reform of the subject.     

The determinants of international student mobility flows: an empirical study on the Erasmus programme

The Erasmus Programme for higher education students is supposed to play an important socio-economic role within Europe. Erasmus student mobility flows have reached a relevant level of two million since 1987, boosted in recent years by the enlargement of the programme to eastern countries. Thereafter, it seems that flows have staggered. In this context, the article analyses the determinants of Erasmus student mobility establishing relevant hypotheses, which arise from the migration theory and gravity models. A panel data set of bilateral flows for all the participating countries has been used in order to test the factors influencing these student flows. Country size, cost of living, distance, educational background, university quality, the host country language and climate are all found to be significant determinants. Results also reveal that there are other determinants, like a country’s characteristics and time effects, which can affect mobility flows. Based on these findings, some general recommendations are put forward to enhance these flows.     

Making citizens,being European? European symbolism in Slovenian citizenship education textbooks

Citizenship education has been an important part of the European Union’s (EU) agenda to integrate a European dimension into schools’ curricula. The usage of European symbolism in citizenship education curriculum material has been an especially important (yet understudied) means not only to promote a distinct European identity and increase knowledge on EU-related topics, but also to regulate (young) EU citizens and population. The paper analyses the content related to the EU and European dimension in citizenship education textbooks and workbooks at the lower-secondary school level in Slovenia. It demonstrates that, through diverse symbolic displays, which are understood as a specific governmental technique, the idea of a European community as a site of opportunities is promoted while students are stimulated to understand themselves as subjects who must be active and responsible EU citizens. Moreover, European symbolism is employed to nurture and promote Slovenian identity as being purely European and, as such, distinct from earlier Balkan-situated, Yugoslav and socialist forms of identity and belonging.
