Analysis of STR loci in Cartagena, a Caribbean city of Colombia

Allele frequencies, together with some parameters of forensic interest were estimated for nine STRs included in the AmpF/STR Profiler kit (CSF1PO, D3S1358, D5S818, D7S820, D13S317, FGA, TH01, TPOX and vWA) in a sample of 215 unrelated individuals from Cartagena (Colombia). For all loci, no significant deviations from Hardy-Weinberg equilibrium were observed. Comparative analysis results between our data and those from other Colombian and African population samples revealed significant differences, except with two Colombian Caribbean Coast sub-regions.     

关于入世后加强上海市外来流动人口长效管理的思考

入世后的上海外来流动人口管理机制,必须满足劳动力要素市场化配置和人才资源自由流动的要求;另一方面,又要结合上海的实际情况,对人口总量予以一定的控制。     

新形势下上海外来流动人口管理的新思路

外来流动人口的增加和外来人口管理方面新政策的出台,使现阶段的外来人口管理工作面临着许多新情况和新问题。因此,我们必须首先转变外来人口管理的传统观念,并在证件管理、流动人口总量、流动人口管理信息化、流动人口社区化管理和自我管理等方面做出根本性的变革。     

高等教育与经济水平关系的统计分析

用人口加权方法对世界各国的高等教育入学率与人均GNP、农业产值比例关系、服务业产值比例关系、城市化人口比例关系进行统计回归,利用软件进行曲线估计,以此确定在众多回归模型中的最适合模型。利用数学模型,可以为我国的高等教育规划提供科学依据。     

福建省人口老龄化发展趋势及战略对策

人口老龄化是世界人口发展的一种趋势。我国在上世纪七、八十年代推行计划生育政策,导致我国人口老龄化又具有一定的特殊性。本文从福建省老年人口发展的概况、现状入手,对其人口老龄化发展趋势进行分析与探讨,并提出若干建议。

城市农民工阶层化问题探讨

随着改革开放以来中国社会转型以及城市化进程加速,城市农民工内部已经发生了阶层分化,从上到下依次划分为准市民身份的农民工、自我雇佣的个体农民工、依靠打工维生的农民工、失业农民工、失地农民工这五个阶层。经济收入的差异是导致城市农民工内部发生分化的最直接、最本质的原因。农民工阶层化未来发展将呈现出城市农民工数量持续增加,农民工阶层在经济层面进一步分化,农民工阶层由基础的经济层面的分化进一步转向政治和社会层面的分化,城市农民工的阶层流动从自发转为自为等趋势。     

Rainfall,population density and voter turnout

We create a dataset linking rainfall amounts to constituency-level election data for Irish general elections over the period 1989–2016. Rainfall is shown to significantly reduce voter turnout. The marginal effect of rainfall on turnout is greater in densely populated constituencies, where a rainy day decreases turnout by as much as three percentage points (or five percent). Using a theoretical framework based on a rational voting model, we propose two possible explanations for this effect. Firstly, if rural voters have higher civic duty than urban voters, they may be immune to rain on election day. Secondly, mode of transport may play a role. Urban voters are more likely to travel on foot or bicycle, whereas rural voters typically travel by car. Therefore, the cost to voting associated with rainfall may be higher in urban areas. Constituency-level data on mode of transport from 1997 to 2016 provides some empirical support for this hypothesis.     

Racialisation of Immigrants at Work: Labour Mobility and Segmentation of Peruvian Migrants in Chile

This article explores the emergent racialisation of Peruvian migrants as one element conditioning the labour segregation that characterises Peruvian insertion in Chile. We understand racialisation as a process of construction of categories in which both individual and collective actors participate, and whose expression is demonstrated by the differentiation and inequality that affects the racialised group. We tackle the articulation of racial differences among individual actors, both Chilean employers and Peruvian migrant workers, to suggest that the attribution of naturalised characteristics to migrants is related to segregation, mobility, and specific trajectories in the labour market.     

新形势下上海地区境外人员“实有人口”管理对策
