城市人口健康的性别差异及影响因素的实证分析

使用CHNS数据,在健康的社会分层模式下探讨城市人口健康的性别公平问题。研究认为,中国城市人口健康存在显著的性别不平等现象,男性健康水平要好于女性,而这种健康的性别差异主要是由于不同性别在社会经济地位上的差异造成的,女性处于明显的弱势地位。     

Impact of artificial fissioning and social networks on levels of aggression and affiliation in primates

Levels of aggression may be affected by stability of social relationships or by population density. A number of studies of nonhuman primates have indicated that spatial density influences agonistic activity levels less than does social density. Artificial fissioning of a captive troop of rhesus macaques was undertaken and the resultant differences in patterns of aggression and affiliation were examined. If population density has a major effect on levels of aggression, then fissioning will result in a decrease in aggression; if social stability has a major effect on levels of aggression, then fissioning is likely to be accompanied by an increase in aggression. An increase in rates of both aggressive and affiliative behavior resulted from artificial troop fissioning. These findings concur with other studies that have concluded that social stability is a more important determinant of primate aggression than is population density. Nonhuman primates use affiliative mechanisms to adjust their behavior when population density increases such that potentially adverse consequences of crowding are avoided.     

Ordinal data,ordered scale points,and order statistics

This paper concerns ordinal responses. An ordered Dirichlet distribution describes prior and posterior beliefs about the cumulative probabilities of response categories. Associating the response categories with intervals of a latent random variable then induces a distribution on the order statistics of that variable. The psychometrician can use the asymptotic theory of order statistics to learn how distributional assumptions about the latent variable effect inference. An example relates the skewness of a latent variable to the proportional odds and proportional hazards models of McCullagh [1980].     

Auditory evoked potentials and sex-related differences in brain development

Auditory evoked potentials (AEPs) were obtained to probe tones which were delivered during the presentation of complex verbal and nonverbal auditory stimulation to 3-month-old infants. Significant sex-dependent AEP amplitude asymmetries were found. Females produced higher-amplitude responses from the left hemisphere and males produced higher-amplitude responses from the right hemisphere during both the verbal and nonverbal presentations. No significant AEP asymmetries were obtained in an independent group of infants that received only the probe tones. These findings are consistent with theories and behavioral data suggesting differences between males and females in the development of language and spatial functions.     

我国艾滋病流行的特点

我国艾滋病的流行有其自身的特点：１．人口多,多发病低,即使以目前的估计ＨＩＶ感染数３０万计,在世界上仍属极低水平;２．传播途径以吸毒为主,性传播为次,二者约为１０与１之比,这和世界各国正好相反;３．高危人群ＨＩＶ阳性率,指性病门诊者,妓女（暗娼）的阳性率都极低,约占０．０６％～０．０７％。目前我国还是以男性吸毒者为主要防治对象。     

Vulnerable Populations in Research: The Case of the Seriously Ill

This paper advances a new criterion of a vulnerable population in research. According to this criterion, there are consent-based and fairness-based reasons for calling a group vulnerable. The criterion is then applied to the case of people with serious illnesses. It is argued that people with serious illnesses meet this criterion for reasons related to consent. Seriously ill people have a susceptibility to “enticing offers” that hold out the prospect of removing or alleviating illness, and this susceptibility reduces their ability to safeguard their own interests. This explains the inclusion of people with serious illnesses in the Belmont Report’s list of populations needing special protections, and supports the claim that vulnerability is the rule, rather than the exception, in biomedical research.     

Women’s Attitudes Toward Testing for Fragile X Carrier Status: A Qualitative Analysis

Fragile X syndrome (FXS) is primarily due to a repeat expansion mutation found in the FMR1 X-linked gene. We have conducted a qualitative analysis of responses from women concerning their attitudes toward testing for carrier status of the fragile X mutation among reproductive-age women. We obtained responses from focus groups including women with and without FXS in their families. We found the following themes: (1) mothers of children with FXS have difficulty formulating their opinions on population screening because of their unique experiences surrounding their own carrier diagnosis and their relationship with their children with FXS, (2) the motivation for carrier testing and need for information differ by family history of FXS and parental status, and (3) the timing of carrier testing with respect to a woman’s life stage dictates whether carrier information will be viewed as beneficial or detrimental. There was evidence that non-carrier women from the general population would be wholly unprepared for positive carrier results. These findings have significant implications for genetic counseling as well as for population screening.     

Atmospheres of the other: Building and feeling Stockholm's orthodox synagogue

In this article, I use the concept of atmosphere to analyse disparate sources related to the process of sacralisation of the orthodox synagogue Adass Jisroel in modern Stockholm. Using the synagogue as an entry point, I explore the affective landscapes related to its unofficially sacred places in firstly a Pietist orphanage and secondly a cinema, and how they shaped inner-communal relations. The material components of Adass Jisroel's sites elicited different emotions from different visiting bodies: its orthodox members aimed to create a space of religious continuity and communal integrity, reformed guests othered the members, while poorer orthodox Jews felt alienated. By analysing these multiple affective experiences linked to material changes of set architectural designs, I outline, for the first time, the orthodox minority's unstable position between fragility and stability in Sweden's capital from 1870 until the 1940s. On a greater scale, through this case study, I propose that the concept of atmosphere provides the field of emotional geography with conceptual muscle to both excavate silenced minority voices, and explore the role of the built environment in eliciting emotions that shape, cement, contest and transform the inner-communal hierarchal landscape that unofficially sacred places are irrevocably situated in.
