Approaches to blockmodeling dynamic networks: A Monte Carlo simulation study

Blockmodeling refers to a variety of statistical methods for reducing and simplifying large and complex networks. While methods for blockmodeling networks observed at one time point are well established, it is only recently that researchers have proposed several methods for analysing dynamic networks (i.e., networks observed at multiple time points). The considered approaches are based on k-means or stochastic blockmodeling, with different ways being used to model time dependency among time points. Their novelty means they have yet to be extensively compared and evaluated and the paper therefore aims to compare and evaluate them using Monte Carlo simulations. Different network characteristics are considered, including whether tie formation is random or governed by local network mechanisms. The results show the Dynamic Stochastic Blockmodel (Matias and Miele 2017) performs best if the blockmodel does not change; otherwise, the Stochastic Blockmodel for Multipartite Networks (Bar-Hen et al. 2020) does.     

“民工荒”背景下新生代农民工劳动力资源问题研究

随着我国社会经济的发展,新生代农民逐渐成为我国目前劳动力市场的主力军。新生代农民具有时代的新特点,他们懂文化有理想有追求。企业传统的职工管理模式已经不能满足他们的利益诉求。伴随着产业转移和经济结构调整,我国东部沿海城市不断发生＂民工荒＂现象。如何在＂民工荒＂背景下考量新生代农民工劳动力资源问题,构建劳动力资源配置机制、农民工权益法律保障机制、新生代农民工教育培训机制,寻求＂民工荒＂问题的解决对策,具有重要的理论意义和现实意义。     

Negotiating Stigma: Lessons From the Life Stories of Gay Men

Gay men, like lesbians, bisexuals, and transgender persons, must negotiate their sexual orientation due to the socially constructed negative view of homosexuality in our culture. Stigma is experienced in various ways according to the meaning that the individual applies to it. This study gleans lessons from the life stories of 15 gay men who recognized the stigma of homosexuality and devised strategies to cope with it. An important finding was that mentors, acting as “cultural brokers,” played a significant role in helping to cope with stigma. The intent of this study is to add to the literature regarding mechanisms that social workers can employ to help gay men cope with stigmatization.     

Do Fair Trade Pricing Policies Reduce Inequalities in Coffee Production and Trade?

This article assesses the Fair Trade pricing model for coffee, investigating the ability of minimum prices and a social premium to reduce price risk and remedy inequalities. It highlights some of the challenges involved in controlling prices. Inequalities exist among Fair Trade‐certified farmers; some are poorer than others, and the poorer ones typically produce less coffee. If Fair Trade succeeds in its aim of raising the prices received by farmers, this will benefit more those farmers producing greater volumes of coffee and who are typically less vulnerable. In addressing inequalities, the Fair Trade social premium is superior to minimum prices.     

Social class as a dimension in casework judgment 1

With few exceptions, outcome studies evaluating batterer treatment groups are inconclusive at best and, at worst, label such treatment programs as ineffectual. This qualitative research study was developed in an effort to understand the forces behind how positive change either happens or is subverted. Through analysis of treatment groups for batterers, the study investigated two questions: How do batterer treatment groups affect the psychological defenses of the members? What types of group dynamics emerge in offender treatment that might be unique to this population and promote defensive change? The theoretical frameworks used in this project include constructs from ego psychology related to defensive maturity and the curative factors in group process, articulated by Yalom (2005).     

有限公司增资扩股的法律机制探析——以公司擅自增资扩股为切入点

有限公司增资扩股的法律机制较为复杂,包括形式上的合同机制以及实质上的公司组织机制与股东保护机制。在合同法、民法视野下分析增资扩股,造成仅关注增资扩股的形式机制与法律效果而忽略实质机制与过程特点的后果,这些思路并不妥当。中国公司法的规定影响了增资扩股的及时性和有效性,有限公司具有回避法定程序、擅自增资扩股的冲动,应当在立法上予以改进,以回应有限公司的融资需求。
