农民工集体行动因素分析

近20年来,农民工问题一直是学术界讨论的热点问题,吸引了诸多学者的持久关注。文章主要探讨当前影响农民工集体行动的相关因素。在回顾西方有关集体行动理论的研究成果和最新进展的基础上,把从勒庞提出的感染理论一直到当代西方的新社会运动理论整合成四个取向,即：社会心理学的解释、行动的解释、结构的解释和文化的解释。文章主要关注剥夺、资源动员和政治机会这三个机制对农民工集体行动的影响。二元Logistic回归分析结果表明,剥夺和资源动员机制对农民工集体行动有不同程度的影响,其中剥夺感是影响农民工参与集体行动的主要因素,而当前政治机会对农民工参与集体行动无显著影响。     

The influence of socio-economic characteristics on the political attitudes of American Indians

We examine the political attitudes of American Indians in eastern Oklahoma where they make up almost 20% of the population. We argue that American Indians in the region play the same role that other minorities in the southern states—notably blacks and Hispanics—do in resisting the region's realignment from the Democratic to the Republican Party. American Indians in the region are populists in that they are economically liberal and religiously conservative. The results of our analysis suggest that the socio-economic characteristics of American Indians play a greater role in explaining American Indians’ political attitudes than their ethnic identification.     

转型期中国公众的分配公平感：结果公平与机会公平

本文考察了中国公众的结果公平感和机会公平感,检验并比较了社会结构解释和相对剥夺解释在中国的适用性。研究发现,大多数公众认可结果公平和机会公平,且机会公平感高于结果公平感,但二者仅微弱相关。结果公平感由收入水平决定,机会公平感主要受教育水平影响。外资和私营单位雇员比国有和集体单位雇员更具机会公平感,城市中下层就业者对结果和机会分配均持批评态度。“个体相对剥夺”而不是“群体相对剥夺”对分配公平感有决定性影响,结果公平感只受横向剥夺影响,而机会公平感则主要受纵向剥夺影响。     

Tavern proximity,tavern density and socio-economic status as predictors of assault occurrence within New Zealand: a temporal comparison

This paper investigates how the associations between tavern proximity, tavern density and area unit socio-economic status with assault occurrence vary in a temporal sense. Using New Zealand Police data specifying the day, time and location of assaults in 2016 and Ministry of Justice data specifying the location of on-licenced taverns, we construct logistic regression models to determine how well tavern proximity, tavern density and socio-economic status predict the occurrence of assaults at peak (Fri 22:00–Sat 03:00 and Sat 22:00–Sun 03:00) and off-peak times. An equal-sized sample of traffic generators (public venues whose primary function is not the sale of alcohol) is constructed and similar procedures applied. We find that tavern proximity and tavern density are stronger predictors of assault occurrence at peak, compared to off-peak, times. Conversely, socio-economic status is a better predictor of assault occurrence at off-peak times. We also find that whilst tavern proximity and density are stronger predictors of assault occurrence relative to traffic generator proximity and density at peak times, the opposite is true at off-peak times. These results suggest that in order to minimise alcohol-related harm, there is a need for policy-makers to take into account the temporal nature of these relationships.     

Coexisting disadvantages across the adult age span: A comparison of older and younger age groups in the Swedish welfare state

Heap J, Lennartsson C, Thorslund M. Coexisting disadvantages across the adult age span: a comparison of older and younger age groups in the Swedish welfare state To experience coexisting disadvantages – the simultaneous lack of several different welfare resources – implies a hampered ability to manage one's living conditions. Here, we study coexisting disadvantages in the oldest population compared with younger age groups in Sweden, by drawing on two linked, nationally representative surveys (n = 5,392). The measurement of coexisting disadvantages included physical health, psychological health, frequency of social contact, cash margin and political resources. The highest odds of coexisting disadvantages were found after age 75 – age groups that are frequently excluded from studies of coexisting disadvantages. This pattern persisted when controlling for socio‐demographic and socio‐economic characteristics. The age pattern was partly driven by the high prevalence of physical health problems in the older population. However, even when excluding physical health problems, the odds of coexisting disadvantages were highest among people older than 85 – the fastest‐growing segment of the population in many Western countries.     

The effect of 6 months of androgen deprivation therapy on muscle and fat mass in older men with localized prostate cancer

Objective.?To evaluate body composition changes, specifically skeletal muscle mass, in men receiving androgen deprivation with luteinizing-hormone releasing hormone-agonist (LHRH-A) for prostate cancer (PCa) in comparison with healthy controls.

Design.?Retrospective analysis of body composition changes in men with prostate cancer receiving LHRH-A therapy from 2 clinical trials compared to men without prostate cancer serving as a placebo-control in another clinical trial.

Setting.?Clinical Research Center in Connecticut.

Participants.?Thirty men (> 60 years) receiving 6 months of LHRH-A therapy for PCa were compared to a healthy group of 25 men without PCa.

Measurements.?Appendicular skeletal muscle/height² (ASM/ht²), lean and fat mass were assessed by dual energy x-ray absorptiometry. Total testosterone levels were assessed by enzyme immunoassay.

Results.?At baseline, 12/30 (40%) of the treatment group and 7/25 (28%) of the control group (p = 0.11) met criteria for sarcopenia. There were no differences between control groups in ASM/ht² or lean mass. The LHRH-A group had a higher percent body fat than the control group, 29.8 ± 6.3 versus 26.3 ± 4.6 (p = 0.02). ASM/ht² and lean mass decreased in the LHRH-A group from 7.5 ± 0.9 kg to 7.3 ± 0.9 kg (?2.3% ± 0.03; p ? 0.001) and 53.5 ± 5.4 kg to 52.3 ± 5.3 kg (?2.1% ± 0.03; p ? 0.001), respectively. There was no muscle loss in the control group. At 6 months, the LHRH-A group had increased percent body fat from 29.8 ± 6.4 to 32.2 ± 5.8 (9.5% ± 0.13; p ? 0.001), whereas the control group had decreased in percent body fat from 26.6 ± 4.6 to 25.3 ± 5.0 (?3.8% ± 0.08; p = 0.02).

Conclusions.?Men undergoing LHRH-A treatment for PCa decreased appendicular skeletal muscle and lean tissue and increased body fat within 6 months of initiation of therapy. Lifestyle changes or medical interventions to minimize the effects of androgen deprivation therapy for PCa deserve investigation.     

An alternative measure of social wellbeing: analysing the key conceptual and statistical components of quality of life

Statisticians, policy makers and social researchers widely accept that there is a need to consider a more nuanced range of measures of quality of life that move beyond the economic domain and that take into account key aspects of an individual's life circumstances. Using data from an Australian household survey, a composite Wellbeing Index was created that covered objective circumstances, with known associations to wellbeing, evaluated from the individual's subjective viewpoint. The robustness of the measure comes from the fact that while covering a broad range of key dimensions, the index only includes the items deemed important components of wellbeing by a majority of respondents. The index was then used to explore the extent to which wellbeing is associated with other dimensions of quality of life that have currency in the contemporary literature. The study contributes to the contemporary debate on social wellbeing and adds new Australian evidence to a body of research that has been mainly based on European and American data.     

Ranking Income Distributions by Deprivation Orderings

This paper has examined the problem of ranking income distributions using absolute deprivation ordering. It appears that the ranking of distributions by this ordering may be more unambiguous than that generated by the relative deprivation ordering. The class of average deprivation indices consistent with the absolute deprivation criterion is also identified.     

论案例指导制度

2005年案例指导制度正式列入最高人民法院的司法改革之中,以实现统一和灵活适用法律的功能。指导性案例和司法解释是最高人民法院实现统一法律适用职能的两种形式,但它们在效力和形式上都不同,指导性案例不具有强制力。指导性案例的形成和效力来源亦不同于英美法的判例,它是下级法院作出的生效判决,由最高人民法院确认发布,下级法院在审判实践中参照适用。在大陆法系与英美法系日益融合的趋势下,指导性案例结合了两大法系的可能优势,形成中国司法改革的制度创新点。     

A new quantitative method for assessing sleepiness: The alpha attenuation test

Abstract

Sleepiness interferes with the ability of night-workers and shiftworkers to safely and effectively perform their jobs, and has been increasingly recognized as a major cause of industrial and transportation accidents. Current methods for the assessment of physiological sleepiness levels, such as the Multiple Sleep Latency Test (MSLT) have several limitations and are particularly impractical in field or occupational studies. In this study, the effectiveness of the Alpha Attenuation Test (AAT) for the quantification of sleepiness has been evaluated and compared to the MSLT during a 40-h sleep deprivation protocol. The AAT, a 12-min eye closed/open protocol, is a quantitative method based on the fact that EEG alpha (8-12 Hz) activity tends to increase with eyes open as individuals get sleepier, while it decreases with eyes closed. In this validation study, the AAT proved to be a sensitive measure of sleepiness induced by sleep deprivation, and it also correlated well with the MSLT. Relative to the MSLT, the AAT has the advantages of being objective, minimally intrusive, and more practical especially in industrial or field studies.
