居民发展能力评估与差异比较——以甘肃省张掖市、甘南自治州为例

阿玛帝业森的能力理论是有关人类文化发展、福利经济学、社会政策研究的哲学论述,是有关个体福利和生活质量评估、社会整顿、政策制定和社会改革等的标准分析框架。本文在简要介绍阿玛帝亚森能力分析的概念和评估方法之后,采用社会学研究方法,通过问卷调查,以黑河流域张掖市与甘南自治州城市居民的能力分析测定为例,尝试在国内开展能力分析的定量研究,并比较影响两地区居民能力的主要因素,分析了提升个体能力,开展能力分析研究的重要意义。     

Pre‐procreative ages in population stability and cyclicity

Age‐specific models of population renewal (with and without feedback) which imply convergence to a stable state for some levels of fertility or feedback may imply the presence of long‐term cycling around a constant or exponentially changing equilibrium for other levels of fertility or feedback. The switch from one regime to the other is a “bifurcation.”; The conditions for bifurcation involve the roots of an analogue of Lotka's Equation.

Typically bifurcation is induced by raising the strength of feedback or the level of fertility. It has been known since the early 1980s, however, that this is sometimes impossible. It is sometimes impossible even with the linear renewal equation itself and with the most basic of non‐linear models, Lee's cohort feedback model.

Here it is proved that this typical route to bifurcation does not fail for these basic models in the presence of a condition which always holds for realistic applications with higher organisms: the existence of a span of ages before the onset of fertility.

Specifically, a strictly positive lower bound on ages of procreation is proved to be sufficient to guarantee the existence of a rescaling of Lotka's Equation for which the real part of some complex root vanishes. This result holds for absolutely Lebesgue‐integrable (signed) net maternity functions on the positive real line and for absolutely summable (signed) net maternities on the positive integers.

It follows that Coale's rescaling device for the analysis of approach to stability in stable population theory can be implemented for all realistic human net maternity schedules. It also follows that the many special cases of the cohort feedback model throughout population biology will all generate persistent cycling instead of stability if feedback is sufficiently strong.     

社会学族群关系研究的几种理论视角

本文主要介绍社会学族群关系研究的主要理论范式,包括源于美国社会的种族主义族群关系理论、社会学族群关系同化范式、权力—冲突范式,并回顾了人类学领域族群性研究的相关启示。传统的客观特征论与晚近对主观认同的强调构成了族群关系与族群性研究的两种主要的分析框架。晚近的研究,强调在民族国家背景下,考虑资源竞争和权力关系对族群关系的影响。     

Testing Serial Correlation in Partially Linear Additive Errors-in-variables Models

This article considers testing serial correlation in partially linear additive errors-in-variables model. Based on the empirical likelihood based approach, a test statistic was proposed, and it was shown to follow asymptotically a chi-square distribution under the null hypothesis of no serial correlation. Finally, some simulation studies are conducted to illustrate the performance of the proposed method.     

Unified multivariate survival model with a surviving fraction: an application to a Brazilian customer churn data

In this paper we propose a new lifetime model for multivariate survival data in presence of surviving fractions and examine some of its properties. Its genesis is based on situations in which there are m types of unobservable competing causes, where each cause is related to a time of occurrence of an event of interest. Our model is a multivariate extension of the univariate survival cure rate model proposed by Rodrigues et al. [37 J. Rodrigues, V.G. Cancho, M. de Castro, and F. Louzada-Neto, On the unification of long-term survival models, Statist. Probab. Lett. 79 (2009), pp. 753–759. doi: 10.1016/j.spl.2008.10.029[Crossref], [Web of Science ®] , [Google Scholar]]. The inferential approach exploits the maximum likelihood tools. We perform a simulation study in order to verify the asymptotic properties of the maximum likelihood estimators. The simulation study also focus on size and power of the likelihood ratio test. The methodology is illustrated on a real data set on customer churn data.     

Strengths-Based Approach and Coping Strategies used by Parents Whose Young Children Exhibit Violent Behaviour: Collaboration Between Schools and Parents

This research study explores the strategies adopted by 60 parents of children between 3 and 9 years of age considered to have engaged in violent behaviour, within the meaning of the Safe Schools Act (Ontario Ministry of Education, Canada, 2000). This legal framework requires parents to be involved in the decisions concerning their children. Parents’ perceptions of their involvement lead them to develop coping strategies enabling them to play a more active role in such decision making. This article analyzes their perceptions according to a strengths-based approach and seeks to provide a mediation perspective to social work practice with families.

The emergence of the emergence-based approach in community practice

Community practitioners are often challenged to work in complex environments and situations that naturally occur in communities. This article focuses on the theoretical and practical use of the Emergence-Based Approach that is relevant for work in complex community situations. Using this approach, the practitioner encourages the emergence of novel ideas and initiatives, and engages a decentralized network of activists, helping them develop their initiatives. Using a field study, we compare this approach to the traditional Outcomes-Based Approach. Although their mindsets are very different, and even contradict one another, we suggest practical ways to combine the two in an effective way.     

Finding common ground: how superdiversity is unsettling social work education

For social work education in the Netherlands, the rapid transition towards superdiversity means that its capacity to adapt to this new reality and to adjust to diverse students’ backgrounds is fiercely challenged. The key aim of this article is to discuss how social work educators are dealing with the unsettling challenges of increasing diversity, based on the research outcomes of an explorative study amongst Turkish–Dutch and Moroccan–Dutch female professionals. Two different groups of educators were asked to comment on the outcomes of this study. One of the dilemmas for educators is to determine what can be considered supportive and inclusive and as reducing inequality in education. The authors used two key theoretical concepts, ‘superdiversity’ and ‘the capability approach’. These theoretical perspectives were used to deconstruct the rather massive concepts of diversity and social justice, by emphasising contextual approaches. Both perspectives stress the urgent need to involve students as ‘active agents of change’, by building a social work community to stimulate and facilitate an on-going dialogue. To successfully fulfil a pivotal role in the upward mobility or emancipation of ethnic minority students, social work education needs to be adjusted to accommodate diverse student groups.
