双语教学已经成为我国课程教学的发展趋势,开展双语教学是培养具有国际合作意识、国际交流能力和具有国际竞争力的外向型人才的客观要求。文章对数理统计双语教学的必要性以及在双语教学的实践中应该注意的问题进行了探讨,并提出了解决问题的方法。     

Confidence Corridors for Multivariate Generalized Quantile Regression

We focus on the construction of confidence corridors for multivariate nonparametric generalized quantile regression functions. This construction is based on asymptotic results for the maximal deviation between a suitable nonparametric estimator and the true function of interest, which follow after a series of approximation steps including a Bahadur representation, a new strong approximation theorem, and exponential tail inequalities for Gaussian random fields. As a byproduct we also obtain multivariate confidence corridors for the regression function in the classical mean regression. To deal with the problem of slowly decreasing error in coverage probability of the asymptotic confidence corridors, which results in meager coverage for small sample sizes, a simple bootstrap procedure is designed based on the leading term of the Bahadur representation. The finite-sample properties of both procedures are investigated by means of a simulation study and it is demonstrated that the bootstrap procedure considerably outperforms the asymptotic bands in terms of coverage accuracy. Finally, the bootstrap confidence corridors are used to study the efficacy of the National Supported Work Demonstration, which is a randomized employment enhancement program launched in the 1970s.

A Multi-Dimensional Conceptual Framework for Trauma-Informed Practice in Addictions Programming

Previous research has conceptualized trauma-informed practice in relation to five key values: safety, trust, choice, collaboration, and empowerment. This research identifies key organizational, programmatic, and interpersonal characteristics in community-based residential addictions treatment programming that exemplify each of these principles. Utilizing qualitative research methods, involving open-ended, one to one interviews with clients in residential substance misuse treatment (n = 41), respondents identified the importance of experiencing “safety” in relation to physical safety, confidentiality, reassurance, rule enforcement, and peer relationships. “Trust” was manifested in sharing, staff availability, nonjudgmental interactions, positive relationship dynamics, and caring. “Choice” was articulated in relation to individual needs, participation, opportunities, and focus of efforts. “Collaboration” was characterized in relation to opportunities for feedback, planning, goal setting, specificity, and support. Finally, “empowerment” was characterized by comfort in sharing, trigger management, trauma awareness, and understanding. The findings provide a conceptual framework for a trauma-informed social services organizational practice environment. Findings can inform adaptations to social service delivery processes and programs to become aligned with the values of trauma-informed practice. Future research can build on this framework by testing the study findings with quantitative methods along with replicating current methods in other social service delivery sectors.

数学建模不仅限于解决实际问题,也可以是数学发展过程中提出的理论问题。基于近年来在大学数学基础课教学中融入数学建模思想的教学实践,论述了其主要思路与做法。介绍了将数学建模思想融入数学基础课教学的两个教学案例,即微积分方法的本质和从方程组出发引入线性相关与线性无关概念。     

Examining implementation and preliminary performance indicators of veterans treatment courts: The Kentucky experience

Veterans’ Treatment Courts (VTCs) are posited as a solution to offer rehabilitation for veterans involved in the criminal justice system. Despite the pervasive implementation of VTCs, there is little research focused specifically on VTC implementation and outcomes, which are based on other problem-solving court models such as drug court. The current study presents qualitative process evaluation data from key stakeholders (n = 21) and veteran participants (n = 4) to show accomplishments, challenges, and lessons learned during first-year implementation at two VTC sites. Quantitative performance data is also presented on veteran participants (n = 19) served during the first year to show: types of services, monitoring, judicial interaction, sanctions/therapeutic responses, and rewards, as well as preliminary data on recidivism. Qualitative data, from both key stakeholders and veteran participants, suggests that offering rehabilitation via various program components, services/referrals, and accountability are critical to the success of the VTC. Data also provides valuable lessons learned for VTC implementation including communication, collaboration, information/protocols, and resources. Performance data shows that a variety of services are utilized and that frequent judicial interaction, drug testing, and sanctions are cornerstones of the VTC. Implications and future directions for research are discussed.     

How can context and discourse affect teachers’ and mental health professionals’ interactions with adults with mental illness?

Patients with severe mental illness may have needs different from those of patients with more limited illnesses and might benefit from other types of intervention than traditional treatment. We interviewed health care professionals from two open, short-term psychiatric wards and teachers from two schools for adults with psychiatric diagnoses. The focus was to explore how differences in contextual factors such as time, tasks, and organizational demands might affect the actions and attitudes of health care professionals and teachers, as well as the potential consequences for patients and students. Data were collected through qualitative interviews. Participants included 14 health care professionals and 14 teachers. The informants worked with patients and students with similar diagnoses and illness durations. All interviews were conducted during the informants’ work time. Findings and interpretations showed that both teachers and health care professionals were engaged in their work and in the wellbeing of students and patients. However, they described marked differences in practice, including the amount of time spent with students/patients, the organization of their work, main tasks, amount of control over their tasks, and social structure. These differences seemed to affect relationships with students/patients, attitudes toward students/patients, norms and values, and opportunities for patient empowerment. Our findings suggest that while existing psychiatric health care might be appropriate for limited short-term problems such as single-episode depression, a model with a supportive environment, based on stable relations and possibility for learning, may improve personal development and mental health for persons with severe mental illness and disturbances in self-experience.     

工业共生研究综述

工业共生作为工业生态系统的重要特征和实现途径已经引起学者们的关注。然而,目前工业共生的理论研究仍处于起步阶段,侧重于相关概念的阐释和理论平台的搭建,大致形成了工业共生链网结构、形成动因、网络治理和评价研究等几个方面。未来的研究应综合运用产业生态学、管理学、经济学相关理论及分析方法深入研究工业共生形成机理和稳定运行的规律性问题,由此为我国发展循环经济、建设生态工业园提供必要的理论支持。     

新自由主义思潮的国际影响及其在中国的渗透

新自由主义是在继承古典自由主义经济理论的基础上,以反对和抵制凯恩斯主义为主要特征的理论思潮、思想体系和政策主张。以美国为首的西方国家在全世界强力推行新自由主义的结果,是给所有实行新自由主义的国家带来了巨大的灾难;最终,美国自身也在新自由主义的实践中付出了沉重代价。目前,处于经济转轨时期的中国也正被新自由主义思潮传播和渗透着,我们必须理性地对待新自由主义对中国经济的干扰,坚决抵制其对中国的侵害。     

取消民族成份作假考生录取资格的合法性质疑

对于民族成份作假骗取高考加分的考生,教育行政部门作出的取消录取资格的处理,在性质上属于行政处罚,应当遵守《行政处罚法》的有关规定。有关行政规范性文件不属于法的渊源,民族成份作假考生的行为不是应当受到行政处罚的违法行为,对考生实施行政处罚缺乏事实根据。行政规范性文件无权设定行政处罚,依据有关行政规范性文件取消考生录取资格,缺乏法律依据。有关部门取消考生录取资格也没有遵循《行政处罚法》规定的程序,不具有合法性。
