民族地区产城教融合的内在逻辑及其实现——基于三螺旋理论的分析

我国少数民族地区社会经济发展滞后,产业基础薄弱,城镇化进程缓慢,其战略地位却至关重要。有效破解少数民族地区发展困境,关键在于实现产城教融合。三螺旋理论对研究民族地区产城教融合问题有着较强的理论适切性,融合的内在逻辑体现为：在产城教三螺旋中,民族产业是先锋核心,中小城镇是载体,职业教育是驱动力,人才是连接的纽带,能够提升三者交互而产生的知识、共识和创新三空间的融合程度,职业教育驱动知识空间、中小城镇承载共识空间、民族产业打造创新空间、人才要素提升三螺旋空间融合度等是推动民族地区产城教融合实现的有效途径。     

高校思想政治教育的新拓展：资源节约教育

高校作为“节约型社会”构建的子系统,必须努力探讨适应建设“节约型社会”的人才培养和教育模式。节约资源是保护生态环境的根本举措,但在高校思想政治教育中,似乎更多关注生态环境教育,忽视了资源节约教育,导致高校思想政治理论课内容结构和体例上不完善,必须重新审视资源节约教育在高校思想政治教育中的价值,探索高校思想政治教育引入资源节约教育的内容以及有效实现形式,并落实在高校思想政治理论课内容上资源节约的道德教育与法律教育的双重构建,为建设节约型社会、确保经济社会的可持续发展提供思想保障。

Public Attitudes Toward Immigration in the United States and Canada in Response to the September 11, 2001 "Attack on America"

In this paper, we describe recent trends in attitudes toward immigration in North America, and we suggest how these attitudes are likely to be affected by the September 11, 2001 "Attack on America." We begin by explaining why public attitudes toward immigration are important, and describe recent trends in these attitudes in the United States and Canada. Then, we apply psychological perspectives to predicting how these attitudes are likely to change in response to the events of September 11th. In particular, we describe expected short-term changes in immigration attitudes and expected long-term trends. We conclude by suggesting that an understanding of the psychological processes underlying unfavorable attitudes may assist in counteracting these effects; we also suggest that policy makers will be faced with the difficult task of balancing the need for a sense of security for members of the national group, and maintenance of the positive features of current immigration policies.     

A Novel Double-Time-Scale Evaluation Method for Ethernet Performability

Generally, there are two ways in Ethernet study, i.e., structural reliability analysis and performance evaluation. The former cannot evaluate the ability of Ethernet to perform particular functionalities precisely, whereas the later ignores random failures, and thus cannot reflect the long-term performance degradation of Ethernet. This article proposes a novel double-time-scale evaluation method to overcome the above disadvantages. The study of Ethernet is conducted in Macro and Micro levels, i.e., the relationship between the number of operational workstations and the random failures is formulated in Macro scale, and the performance is modeled with the number of operational workstations in Micro scale. This method can synthesize the effect of reliability and performance, and evaluate the Ethernet in a systematic way effectively. It reflects the actual influence of random failures on Ethernet performance degradation. Because the impact of main Ethernet design parameters is included in the analytical model of Ethernet performability, this method offers a powerful tool for design optimization of the Ethernet.     

Applying a marginalized frailty model to competing risks

The marginalized frailty model is often used for the analysis of correlated times in survival data. When only two correlated times are analyzed, this model is often referred to as the Clayton–Oakes model [7,22]. With time-to-event data, there may exist multiple end points (competing risks) suggesting that an analysis focusing on all available outcomes is of interest. The purpose of this work is to extend the single risk marginalized frailty model to the multiple risk setting via cause-specific hazards (CSH). The methods herein make use of the marginalized frailty model described by Pipper and Martinussen [24]. As such, this work uses the martingale theory to develop a likelihood based on estimating equations and observed histories. The proposed multivariate CSH model yields marginal regression parameter estimates while accommodating the clustering of outcomes. The multivariate CSH model can be fitted using a data augmentation algorithm described by Lunn and McNeil [21] or by fitting a series of single risk models for each of the competing risks. An example of the application of the multivariate CSH model is provided through the analysis of a family-based follow-up study of breast cancer with death in absence of breast cancer as a competing risk.     

论生态文明背景下环境立法理念的演进

人类面临的严重生态危机既有制度层面的原因,也有价值层面的原因,但主要还是价值观念的因素.每一次环境运动都是对旧价值观的扬弃,从而使人类道德共同体的范围不断扩大.而这种价值观的变革也为立法提供了伦理基础,并最终反映在法律制度中.本文在探讨生态文明背景下环境立法理念的演变的基础上,对人与自然关系进行历史反思,试图通过建立"生态主义"的环境法法理基础,确立人与自然和谐相处的环境法价值取向,并围绕人与自然的共同利益之保护重新构建法律体系.     

Fuzzy Risks and an Updating Algorithm with New Observations

Concerning the essence of risk, we suggest a new definition of risk: a scene in the future associated with some adverse incident. In many cases, risks are rather fuzzy for our perception because of the shortage of knowledge or information about the systems that determine the adverse incidents. We introduce a concept of fuzzy risk based on the new risk definition and fuzzy sets. And, in this article, we suggest a fuzzy average algorithm to update a fuzzy risk that stores all information from the original data. To illustrate the algorithm, we update a soft risk map of flood where the fuzzy risks are calculated using the interior-outer-set model.     

论我国社区教育体系的建构

21世纪,教育发展的一个重要趋势是终身教育.社区教育是形成全面学习、终身学习的学习型社会的主要载体,也是终身教育的基本形态和根本保证.社区教育是一种区域性、有组织、社会一体化的教育活动,是社会发展和时代变革的产物.我国在社区教育方面起步较晚,理论基础不足,可借鉴美国社区教育实践经验,以推动我国社区教育体系的建立和发展.
