城市生活垃圾产量的组合预测

引入一种新的预测垃圾产量的方法——组合预测方法,该法能够综合利用不同预测方法提供的信息提高预测精度。结合厦门市1996～2008年的垃圾产量,分析不同预测方法的预测精度,并预测5年后的垃圾产量。通过研究发现:单一预测模型中,线性回归法和年增长率法的预测结果偏小,误差较大,灰色理论GM(1,1)的预测结果偏大,误差较小,基本在10%以内;组合预测模型的预测精度高于单一预测模型;厦门市城市生活垃圾年平均增长率约为10%,低于国民生产总值和社会消费品零售总额年平均增长率,高于城镇居民消费性支出年平均增长率。     

Volunteers in Special Libraries

The contributions of volunteers in special libraries have not been well-documented or researched. However, anecdotal evidence shows that volunteers have played a key role in the formation of many special libraries and continue to lend their skills and knowledge to these libraries. This column explores examples from the literature and gives a brief case study on the various ways philatelic libraries use volunteers. The scope of the column includes traditional unpaid volunteers, remote volunteers, crowdsourcing, internships, job training programs, and other voluntary or nontraditional work. Volunteer labor is far from free in terms of cost to the organization, but can provide benefits beyond simply unpaid labor including subject expertise, special skills, and community building. Special libraries looking to begin or expand volunteer programs are advised to study the lessons learned from other types of libraries and organizations with successful volunteer programs. Successfully managing volunteers requires careful planning and coordination just as managing paid staff does.     

心理授权对饭店实习生留职意向的影响研究

“用工荒”和“留人难”近年来已成为我国饭店业发展的瓶颈和难题。研究以286名饭店高职实习生为研究对象,分析了饭店实习生心理授权、工作满意度和留职意向之间的内在联系。得出以下结论：心理授权对实习生留职意向的影响与对在职人员的不同,表现为自主性对留职意向的影响不显著;心理授权四个维度中的工作影响力、工作意义和胜任力不仅直接对留职意向产生影响,而且工作意义和胜任力还通过工作满意度间接影响留职意向;相比工作满意度,实习生的心理授权感知水平对提高饭店实习生留职意向发挥更重要的作用。

Study on the comprehensive combustion kinetics of MSW

The combustion behavior of typical components of MSW was examined with a thermal gravimetric analyzer (TGA). The experiments were done over the temperature range of room temperature to 1000℃ at a heating rate of 10 oC/min and in an oxidizing atmosphere. The results indicated that the entire weight loss process of each typical component of MSW consists of one to three distinct combustion stages. The combustion of typical components of MSW could be modeled by one to three independent reactions. The corresponding parameters of typical components of MSW such as activation energy, pre-exponential factor, and reaction order were determined. The calculated results using the comprehensive kinetic model composed of one to three independent and consecutive reactions, agreed well with experimental results.     

Towards collective work and responsibility: Sources of support within a Freedom School teacher community

Alternative and parallel schooling contexts such as the Children's Defense Fund Freedom Schools^® provide educational experiences for U.S. K–12 students grounded in notions of social justice and culturally responsive teaching. College-aged young adults known as “servant-leader interns” are the teachers in this context. In this article, the author examines the nature of the various ways in which servant-leader interns were supported in their development as teachers both at the national training institute and at their local site. This discussion gives explicit attention to the kinds of deliberate support intended by the Freedom Schools program and the kinds of support that the servant-leader interns created or initiated on their own. Implications for teacher support that occur in alternative and parallel schooling contexts are discussed.

Designing for Quality: Distance Education Rubrics for Online MSW Programs

ABSTRACT

There has been a rapid increase in the number of online MSW programs in the past decade without a commensurate body of literature on their administration. This article acquaints MSW program faculty and administrators with quality assurance rubrics, which are research-informed tools intended for use by distance education providers to develop, support and manage high quality online courses and programs. Graduate programs that are in the process of considering or actually designing an online delivery option, as well as those that are currently implementing online programs, may benefit from the use of such quality assurance rubrics.     

学前教育实习生实习前后心理健康状况调查研究

教育实习是学前教育学生第一次承担幼儿教师职责,角色的转换会造成较大的心理压力。及时了解、掌握实习生的心理健康状况,进行有针对性的培训、辅导是使实习生顺利渡过实习期的关键。本研究采用症状自评量表对学前教育专业实习生的心理健康水平进行测查,发现:(1)与国内大学生常模相比,我院学前教育专业实习生的心理健康水平偏低,其中人际关系敏感、抑郁、焦虑、恐怖等4个因子得分显著高于常模;(2)学前实习生的症状自评量表中各因子得分在实习前与实习后未出现显著差异,这与其他专业实习生有所区别,究其原因主要是实习工作适应难度大及从业前景不乐观所致。     

Teaching Interpersonal Psychotherapy (IPT) in an MSW Clinical Course

Interpersonal Psychotherapy (IPT) is a relatively brief psychodynamic intervention of approximately 12 sessions focusing on how current interpersonal relationships have contributed to a person’s mental health symptoms. Areas targeted for work involve significant role transitions, grief and loss, and interpersonal disputes. IPT is an evidence-based treatment for depression, bulimia nervosa, and binge eating disorders. Despite these advantages, social work students rarely receive instruction on the delivery of IPT in their graduate programs. The purpose of this project, therefore, was to begin to address this gap by implementing an IPT component in a clinical practice course and testing student knowledge pre- and post-test. An example of sample assignments involving application of IPT to student fieldwork is provided. The sample in this study involved a small number of students enrolled in a clinical course taught in the first semester of the second year of training. Students improved their knowledge score at a statistically significant level. Implications of the study are explored, with the main conclusion being that more clinical majors in MSW programs be exposed to IPT.
