我国区域刑事法律冲突初探

我国各民族之间的差异、民族区域自治制度及其自治权的存在是我国区域刑事法律冲突产生的基本原因,而通过制定顾全大局、兼顾特别的变通性、补充性刑法规范,可缓解这一冲突;通过加快少数民族地区的发展步伐,逐步消除民族之间的政治、经济、文化上的差距,进而达到彻底消除这一冲突,实现法制统一的良好局面。     

A Numerical Solution to the Nonhomogeneous Two-Stage MVK Model of Cancer

In this article, we describe a straightforward method for solving the probability of at least one malignant cell by time t, and the associated hazard function, in the general (i.e., nonhomogeneous) two-stage Moolgavkar-Venzon-Knudson (MVK) model of cancer. The method consists of solving four coupled ordinary differential equations derived from the Kolmogorov backward equations for this process. The relationship of this method to previously proposed solutions is discussed.

高Si/C高强度铸铁中C、Si、Si/C的作用及其选择

本文叙述了高Si/C高强度灰铸铁中碳、硅元素存在的形式及其对结晶过程的影响。试验表明,当碳当量一定时,随着Si/C的升高,初生奥氏体枝晶数量增多并且细化和强化,从而构成了强度的基础。该铸铁的强度模式应为“初生奥氏+共晶团”。本文对E型石墨存在的必然性和合理性也进行了讨论。

Mobility types,transnational ties and personal networks in four highly skilled immigrant communities in Seville (Spain)

In this study, we explore how different mobility patterns influence the composition and structure of the transnational social support networks and how personal networks allow us to elicit insightful data of mobile individuals. Ninety-five mobile individuals were selected from four distinct communities based in Seville (Spain), namely: Erasmus students, Flamenco artists, musicians from the symphonic orchestra and partners of European Commission researchers. Data were collected through an electronic survey sent by email with multiple name generators and a structured face-to-face interview utilizing a network visualization tool, VennMaker. Two distinct methods, namely qualitative case studies and cluster analysis were used to characterize mobility types. Findings reveal a heterogeneous foreign population, in which different forms of mobility are reflected in the personal networks of mobile individuals. Respondents who were settled in the city were more likely to have networks in which social support was mainly derived by hosts and people in the host location and with whom they communicated predominantly through face-to-face communication. Those who were in the host location for a study exchange, knowing that return to the county of origin is imminent were more likely to have networks linked to the home location. They relied heavily on strong transnational ties in the home country using social media to sustain their relationship. Respondents with an itinerant mobility profile, also had networks dominated by strong transnational ties, however, such ties had a higher degree of geographical spread due to previous international mobility. Participants who had a high number of hosts in the network but low connection between the ties were more likely to be linked to a specific subculture in the host society. The integration in the host location follows a different pattern to other settled individuals, mainly because their connection in the city tends to be community specific.     

Gender and Transnational Gossip

Transnational social networks powerfully shape Mexican migration and enable families to stretch internationally. In an atmosphere of such high dependence on social networks, it would be rare for families not to be affected by the opinions of others. This article analyzes this often-overlooked aspect of social networks, gossip. I analyze gossip stories prevalent for one type of migrant family, those in which parents and children live apart. Drawing on over 150 ethnographic interviews and observation with members of Mexican transnational families and their neighbors in multiple sites, I describe both parents’ and children’s experiences with transnational gossip. I show that in a transnational context, gossip is a highly gendered activity with different consequences for men and women. Although targeting both women and men, transnational gossip reinforces the expectations that mothers be family caregivers and fathers be family providers even when physical separation makes these activities difficult to accomplish.
