券商业绩起伏与沪深股市波动的关系探析——基于2009-2013年面板数据的实证研究

为了探究券商业绩与股市波动的关系,选取不同区域的10家已上市券商为样本,采取2009—2013年的数据,通过Stata12软件采用多元经典回归方法对此进行实证研究。研究结果显示:券商的业绩明显正向地影响到沪深股市的量价波动;股市波动十分显著地影响到券商的业绩起伏,沪深股市涨幅对券商总资产增长率、经纪业务利润都有显著的正向影响,成交金额增长有利于券商利润提高,而沪深股市振幅则对券商业绩有一定程度的负面影响。券商需注重差异化竞争,及时调整自营业务的总量与结构,彻底完成集中交易模式以提高经纪业务的毛利率。

Urbanised soundtracks: youth popular culture in the African city

This article interrogates the participation of youth in constructing and defining the African urban landscape. It seeks to examine youth popular culture and performance practices that combine indigenous sound aesthetics with enactments of cultural memory to construct the urban landscape of Botswana. Particularly, the article examines youth cultural and expressive forms such as hip-hop and Kwaito musical genres, popularised traditional music, and the satirical dramatic impersonations of radio personality Dignash Morapedi. These performances elaborate African syncretic formations that underscore the power of African popular culture to integrate, reinvigorate, and transform various social spaces and identities. Urban youths use these performance forms to demonstrate how innovative practices could be used to interrogate social realities such as unemployment, poverty, and HIV/AIDS. Using the notion of “urban noise,” the article teases out a strategy of critique that articulates the various ways that the youth acoustically construct, produce, and navigate the African city.     

农村青年婚姻市场层级化的社会学分析

当前农村青年婚姻市场上,以"家庭地理位置"和"家庭经济条件"为分层标准,农村男青年被划分为不同的层级。不同层级的男青年在婚姻市场上有着不同的处境:较高层级的男青年拥有较大的择偶主动权,中层的男青年也基本能够进入婚姻,较低层级的男青年择偶困难,成为大龄未婚男青年的风险较大。因此,形成不同层级的原因是性别比失衡使得农民经济上的分化在婚姻市场上凸显出来,市场经济冲击下的农民择偶观念理性化,打工潮加剧了农村婚龄人口性别比的失衡。     

From Sex to Gender: The Feminisation of Migration and Labour-Market Insertion in Spain and Portugal

The aim of this article is to study the feminisation and masculinisation of migration and the insertion of the migrant population into the labour market in Spain and Portugal from the perspective of gender. Rather than focusing on the appearance of the demand for migrant labour in social reproduction work, we analyse the situation of both men and women in highly feminised and masculinised activities by studying the impact each exerts on the other, and the way in which this conditions the gender breakdown of the migrant population. We provide a historical view of the work of migrants in the care and cleaning sectors, comparing it with male migrant employment—mostly in construction—and analysing the gendered breakdown of migrant communities. We argue that, in contrast to the generally accepted discourse on the international scene, there has not been a steady evolution in the feminisation of migrant labour in Spain and Portugal. Instead, the presence of migrant women on the labour market fluctuates in accordance with a specific set of variables: welfare state and care regimes, immigration policies, historical links influencing the national origin of migrants, the housing situation, labour markets and the respective economic situations in the construction industry and in domestic and care work.

创业投资项目回报率及其影响因子研究——以创业板上市公司为例

以有创投背景的创业板上市公司为研究样本,选取了146个数据齐全的投资案例,对我国创业投资项目回报率及其影响因子进行了描述性统计、相关性分析和回归分析。研究结果表明,代表投资方案设计的投资周期、初始投资额、初始投资股权比例、被投资项目所处行业的四因素对投资回报率具有显著影响;代表投资机构投资经验和实力的从业时间、注册地、管理基金规模、历史投资案例数、历史退出案例数的五因素对投资回报率没有显著影响,说明创投机构的历史投资经验和积累对投资回报率的影响并没有表现出规律性的关系,这一结论将对完善我国资本市场提供借鉴。
