大学生返乡创业生态系统：目标、要素、机理和对策*

创业生态系统从生态系统的视角揭示了创业生态中创业主体、创业要素、创业环境以及各要素之间的相互作用。创业生态系统是一个复杂的自适应系统,其具有复杂的自适应系统的各项特征,从系统的角度来讲,其具有系统的目标、要素、运行机理和系统边界。本文以大学生返乡创业生态系统为例,从系统目标、系统要素和系统的运行机理三个方面立体剖析了创业生态系统的内涵和外延。同时,对大学生返乡创业生态系统的目标设定、大学生返乡创业生态系统各要素的构成以及大学生创业生态系统的运行机理进行了分析,对强化大学生返乡创业生态系统的构建提出了对策建议,为促进大学生返乡创业和乡村振兴提供参考。     

Passage a l'age adulte et mobilite spatiale

Starting with longitudinal data on two cohorts of women living in the Alpes-Maritimes in 1982 (a sample of 1,500 women in total) we try to establish the role of the spatial distribution of opportunities at a number of key stages in the life cycle: marriage, birth of first child, making professional use of qualifications, confrontation of a situation of professional risk and professional mobility during the years immediately following the completion of studies. The underlying hypothesis is that control of social location often depends on the control of spatial location.     

Accumulation of Welfare Problems in a Longitudinal Perspective

In this article we study the bias caused by the conventional retrospective measurement of parental high cultural activities in the effects of parental high cultural activities and educational attainment on son’s or daughter’s high cultural activities. Multi-informant data show that there is both random measurement error and correlated error in the respondent’s report of parental high cultural activities. Correlated measurement error is the consequence of the fact that adult children who have higher rates of high cultural activities, report higher levels of parental cultural activities than the parents themselves do. When controls for both types of measurement error are included in structural models, the total intergenerational effect of parental high cultural activities appears to be larger than in a model without controls for measurement error, but the direct intergenerational effect is not biased if educational attainment is controlled for. The effect of educational attainment on high cultural activities is larger in models that correct for measurement error. In addition, the effect of educational attainment is stronger than the effect of parental high cultural activities, both with and without correction for measurement error.

Designed for Patience: The Significance of Internal Factors in the Ukrainian and Belarusian Transitions

This paper focuses on Belarus in order to find explanation as to why Alexander Lukashenko was able remain the authoritarian leader of Belarus, while in Ukraine the position of the political elite had proved less stable and collapsed in 2004. We seek to determine whether the internal factors (macroeconomic conditions, standard of living, the oppressive nature of the political system) play a significant role in the operation of the domino effect. This article emphasises the determining role of immanent internal factors, thus the political stability in Belarus can be explained by the role of the suppressing political regime, the hindrance of democratic rights and the relatively good living conditions that followed the transformational recession. Whilst in Ukraine, the markedly different circumstances brought forth the success of the Orange Revolution.      

Lifetime estimation from doubly censored data and dirichlet process prior knowledge on the observable random vector

The purpose of this paper is to present a nonparametric Bayesian procedure for estimating a survival curve in a double censoring situation. Assuming a proportional hazard rates model, we propose a consistent estimation of lifetime, based on a Dirichlet process prior knowledge on the observable random vector. Some large sample properties of this estimator are also derived, We prove strong consistency and asymptotic weak convergence to a Gaussian pro cess. Finally, a simulation study is presented in order to analyze the behavior of the proposed estimator, and establish some comparisons to other estimators.     

Reactions to Research Participation in Vulnerable Subgroups

This paper describes the extent to which vulnerable individuals (defined by economic, social, psychological, physical health, and child maltreatment status) react to research participation. As part of an ongoing longitudinal study, participants (N = 896) completed a lengthy and intrusive in-person interview and provided a small amount of blood through finger pricks. At the end of the interview, participants were asked eight questions about their reactions to the research experience. Vulnerable individuals in general agreed more strongly about having an emotional reaction, but were not less willing to continue to participate. In addition, psychologically vulnerable individuals more strongly agreed they would continue to participate, were treated with respect and dignity, and found their participation meaningful. Compared to whites, nonwhites reported stronger agreement about the meaningfulness of the research and the belief that their responses would be kept private. Like others, individuals vulnerable by virtue of their prisoner status or homelessness (past or current) agreed more strongly about having an emotional reaction to the interview, but otherwise did not differ in their reactions. These results suggest that researchers and institutional review boards should not be deterred from conducting research on sensitive topics with potentially vulnerable populations.     

The child welfare service's assessments in custody cases that involve minors

The percentage of breakdowns in marriages, cohabitations and civil partnerships is increasing in the Western world, resulting in questions of child custody. In Norway and other Western countries, there is little knowledge of the support system's work in child custody cases. This article focuses on the assessments Norwegian child welfare service employees conduct in 37 cases about child custody. We explain why they sometimes conduct investigations of reports and at other times do not.

‘Street-level bureaucracy’ is the theoretical reference framework for interpreting the interviews. Assessments and decisions of the child welfare service in custody cases vary from one service to another. It is relatively difficult to predict whether the notifications will be investigated or dropped. Decisions are the result of a jigsaw puzzle of risk assessment, interpretations of legislation, cooperative procedures and an understanding of the county social welfare board. Notifications concerning violence and notifications from family counselling offices stand out since generally they result in investigations.

Child welfare services' handling of notifications regarding custody questions is challenging as these cases are in the grey zone between the Children Act and the Child Welfare Act. Child welfare workers want clearer guidelines for the cases on which they are to work. However, new rules cannot replace the professional and ethical assessments the child welfare service workers have to make in each individual case.     

Not Your Average Teen Horror: Blood and Female Adolescence in Richard Bates’s Excision (2012)

ABSTRACT

Richard Bates’s film Excision (2012) uses blood as a metaphor to interrogate how cultural constructions of femininity affect the development of adolescent girls. Contrary to other horror films, which frequently depict adolescent girls as examples of the ‘monstrous-feminine’, this film about a girl who decides to perform a lung transplant on her sister explores the horrors caused by restricting conceptualisations of feminine bodies and identities. The film’s focus on blood interrogates problematic ideological connotations between menstruation and sexual promiscuity, and questions the veracity of supposedly realistic representations of the female body in contemporary advertising. Its protagonist’s adaptation of the ‘mad scientist’ persona gradually turns her into a character resembling Frankenstein, whose monstrosity highlights her inability to either conform to or escape from femininity as a cultural construct. Teen horror, the film suggests, is not caused by blood and bodily matter, but by extra-textual stereotypes and gender inequality.     

Mild Intellectual Disability Associated with a Progeny of Father-Daughter Incest: Genetic and Environmental Considerations

We report the case of a 34-year-old female resulting from a father-daughter sexual abuse and presenting a phenotype of mild intellectual disability with minor dysmorphic features. Karyotyping showed a normal 46, XX constitution. Array-based comparative genomic hybridization (array-CGH) revealed a heterozygote 320kb 6p22.3 microdeletion in the proband, encompassing only one known gene, and therefore unlikely to be the cause of the phenotype. However, the role of other genetic factors, such as a recessive condition, could not be ruled out as a putative cause for the phenotype. On the other hand, the role played by a heavily detrimental familial situation on the development and outcome, and possibly leading or contributing to a mild intellectual disability, should be taken into account.
