论科学技术的政治功能

科学技术是政治文明进步的杠杆,在政治意识文明、政治制度文明和政治行为文明的进步中,科学技术具有十分重要的作用。政治家是政治文明的总设计师,是政治意识文明的倡导者、政治制度文明的建立者和政治行为文明的发起者。政治家在决策中同样受到科学技术发展的影响。同时对科学技术作用于政治文明的机制进行了分析。     

Mothering and everyday life during and in the aftermath of domestic violence among women with immigrant backgrounds in Norway

This paper focuses on how immigrant women experience and negotiate their everyday life with children prior to and after leaving a violent partner. Twenty‐three women staying at domestic violence and abuse shelters with their children were interviewed about their experiences with assistance services and their everyday life with their children. At the time of the interviews, most of the women were legally separated or divorced and were either living in or in touch daily with shelters. In this paper, we look at some of the challenges that women face when exposed to violence in a relationship that involves children. Being exposed to violence from a partner raises a number of economic, practical, and emotional concerns, both prior to and after leaving. For the mothers in our study, maintaining a regular routine is key to making the children feel safe in an unpredictable setting. For many, economic dependence on the partner is replaced with economic dependence on assistance services after leaving the partner. Services must recognize that providing help to mothers who have left a violent partner constitutes more than just practical support but is crucial for mothers' ability to re‐establish a predictable everyday life with their children.     

The intersection of class origin and immigration background in structuring social capital: the role of transnational ties

The study investigates inequalities in access to social capital based on social class origin and immigration background and examines the role of transnational ties in explaining these differences. Social capital is measured with a position generator methodology that separates between national and transnational contacts in a sample of young adults in Sweden with three parental backgrounds: at least one parent born in Iran or Yugoslavia, or two Sweden‐born parents. The results show that having socioeconomically advantaged parents is associated with higher levels of social capital. Children of immigrants are found to have a greater access to social capital compared to individuals with native background, and the study shows that this is related to transnational contacts, parents’ education and social class in their country of origin. Children of immigrants tend to have more contacts abroad, while there is little difference in the amount of contacts living in Sweden across the three groups. It is concluded that knowledge about immigration group resources help us predict its member's social capital, but that the analysis also needs to consider how social class trajectories and migration jointly structure national and transnational contacts.     

论清代“环湖八族”形成的历史背景

公元16世纪上半叶,大批蒙古族靠武力占据了环青海湖地区的肥沃牧场,而世居当地的藏族各部落被迫渡黄河南迁.19世纪中叶,藏族抓住青海蒙古族日趋衰落、鸦片战争及太平天国起义导致满清政府无暇顾及青海的有利契机,率众北渡黄河,从而形成了青海今天的蒙藏民族分布格局.本文结合汉藏史书文献,探计了"环湖八族"形成的历史背景.     

我国财政赤字和货币供应量联动性的实证模型分析

近期以来国际金融危机的加深,进一步揭示了一国财政赤字与宏观经济之间的深刻关联。进入新世纪以来,我国运用财政赤字的手段和方法不断改进,对于我们应对国际金融市场的动荡、促进内需和经济增长起到了很大作用。但同时,财政赤字与货币发行量之间不可调和的正向关系,也给我国经济体系带来了一定的隐患。因此,通过理论梳理与实证分析来理清赤字规模和货币供应量之间的关系,有助于我们今后宏观经济管理手段和金融市场监管能力的提升。     

句式中介词结构漂移的语篇语用解释

句式具有语篇功能,语篇功能制约句法结构。文章主要考察了否定句、假设句、条件句、时间状语从句句中介词结构的分布,这些句式在语篇中具有非现实性,不在叙述的主线上,属于背景信息,具有低及物性的特点。介词结构在小句中的漂移受及物性决定,高及物性的小句中介词结构位于动词后,而低及物性的小句中介词结构位于动词前。通过溯因推理,介词结构在这些特殊句式中只能处在主谓之间,处在动词之后不合语法。研究发现,真实语篇语料的考察证实了这一推测。     

我国企业海外撤资的实物期权分析

由于世界经济形势变化、地区政局不稳和企业对国际市场的误判,我国部分对外投资企业亏损严重,面临着从海外撤资的决择。利用实物期权法分析企业退出问题,参照贝尔曼方程,构建撤资决策的实物期权模型,分析对外投资企业撤资决策的价值。算例分析表明,对外投资企业选择的贴现率、利润的波动率和撤资成本的变化均能影响撤资的时机和方式。我国对外投资企业应根据形势变化和自身实力,不断加强自身抵抗风险的能力,灵活选择趁机抢占国外市场的进攻策略,或尽早撤出以获得放弃期权价值的防守策略。     

Mobilisation strategies of individual and institutional actors in Brussels’ artistic and cultural scenes

Though sharing a common territory, the cultural spaces of Brussels are divided according to a complex structure where Francophone and Flemish Communities play a dominant role. These two language-based communities set separate cultural policies and programming for their residents in Brussels. Within this fragmented structure, local socio-cultural actors have mobilised promoting cross-Community collaboration towards a shared vision for the Brussels-Capital Region (ex. Cultural Plan for Brussels). Further, individual artists themselves have developed strategies to participate in Community-defined cultural programming and to gain recognition for their talent as local (Bruxellois) artists regardless of their ethnic, linguistic or migrant background. This article explores how socio-cultural actors and artists have mobilised to reframe ‘culture’ in Brussels, and to gain access to cultural venues particularly in the case of migrant and migrant-origin artists whose engagement and recognition in Brussels’ cultural scenes have been little studied.     

Implementing a diversity policy through public incentives: Diversity Plans in companies of the Brussels-Capital Region

ABSTRACT

The development of diversity policies in the private sector is mostly a result of a voluntary engagement of companies. When interested, they decide about the ways and goals of such policies, implications for human resource management and the inclusion of staff with a migration background. This article explores a specific situation in which public authorities offered support and resources to companies in order to develop diversity policies. I present a first analysis of the implementation dynamics of the Brussels Diversity Plan, a policy instrument launched in 2007 by the Government of the city-region of Brussels. Building on the theoretical tools of the political sociology of public policies, I use qualitative material (interviews and administrative documents) to explore implementation processes in three private companies. I show that public authorities can play a decisive role in developing diversity policies in the private sector through incentives rather than constraint. Yet, the room for manoeuver offered to companies leads to important variations regarding how processes unfold and the results achieved.     

The time‐dependent “cure‐death” model investigating two equally important endpoints simultaneously in trials treating high‐risk patients with resistant pathogens

A variety of primary endpoints are used in clinical trials treating patients with severe infectious diseases, and existing guidelines do not provide a consistent recommendation. We propose to study simultaneously two primary endpoints, cure and death, in a comprehensive multistate cure‐death model as starting point for a treatment comparison. This technique enables us to study the temporal dynamic of the patient‐relevant probability to be cured and alive. We describe and compare traditional and innovative methods suitable for a treatment comparison based on this model. Traditional analyses using risk differences focus on one prespecified timepoint only. A restricted logrank‐based test of treatment effect is sensitive to ordered categories of responses and integrates information on duration of response. The pseudo‐value regression provides a direct regression model for examination of treatment effect via difference in transition probabilities. Applied to a topical real data example and simulation scenarios, we demonstrate advantages and limitations and provide an insight into how these methods can handle different kinds of treatment imbalances. The cure‐death model provides a suitable framework to gain a better understanding of how a new treatment influences the time‐dynamic cure and death process. This might help the future planning of randomised clinical trials, sample size calculations, and data analyses.
