Street Ball,Swim Team and the Sour Cream Machine: A Cluster Analysis of Out of School Time Participation Portfolios

Adolescents spend only a fraction of their waking hours in school and what they do with the rest of their time varies dramatically. Despite this, research on out-of-school time has largely focused on structured programming. The authors analyzed data from the Educational Longitudinal Study of 2002 (ELS:2002) to examine the out-of-school time activity portfolios of 6,338 high school sophomores, accounting for time spent in school clubs and sports as well as 17 other activities. The analytical sample was balanced with respect to sex and racially and ethnically diverse: 49% female, 67% White, 10% Latino, 10% African American, and 6% Asian and Pacific Islander. Approximately 76% of the sample attended public schools, 30% were in the highest socioeconomic quartile, and 20% were in the lowest socioeconomic quartile. The authors identified five distinct out-of-school time activity portfolios based on a cluster analysis. The demographic profiles of students by portfolio type differed significantly with respect to sex, race/ethnicity, socioeconomic status, school type and location. Students by portfolio type also differed significantly in terms of measures of academic success, school behavior, victimization and perceptions of school climate, controlling for covariates. These findings underscore the importance of more complex considerations of adolescents’ out-of-school time.

The centrality of labor time in South African gold mining since 1886

Labor time, as a dimension of South African mining labor history, has been ignored, both conceptually and historically. This article remedies this yawning gap by presenting primary and secondary evidence which demonstrates the centrality of labor time in South African gold mines since the discovery of gold in 1886. To this end, labor time is traced in two ways. Part I tracks industrial working time by tracing the length of the working day and week. Part II tracks the ever-increasing length of the African migrant labor contract. While industrial working hours remain remarkably stable for almost a century, the migrant labor contract systematically increases over a similar period. These two measures of labor time eventually coincide when the migrant labor system dissolves and black African workers take annual leave together with their compatriots across the racial divide. The explanation for the mining industry’s long struggle to both maintain relatively long working hours and increasingly maximize the length of the migrant labor contract is construed as completing the received wisdom of Harold Wolpe's much celebrated and criticized `cheap- labor' thesis. (Wolpe, “Capitalism and Cheap Labor Power.”)     

Local government reforms: between multifunction and single-purpose organisations

The paper argues that, in ‘revisiting’ the referred-to article published back in 2004, the concept then guiding the analysis would need to be modified particularly on three scores. For one, in order to achieve a more adequate comparison the country selection should be expanded beyond the earlier sample (UK, France, Germany and Sweden) to also capture Southern and Central Eastern European countries. Second, the ‘developmental’ (‘over time’) analysis of the pertinent institutional changes should be further accentuated and complemented by proceeding ‘by (developmental)stages’ instead of ‘country by country’. Third, while still deeming the distinction between ‘multifunction’ and ‘single-purpose’ organisations fruitful to guide a ‘government versus governance’ analysis and interpretation, the distinction between ‘political rationality’ and ‘economic rationality’ should be added with the former (ideal-typically) identified with elected (local) government and the latter seen characteristic of many of the actors in the governance-typical actor networks.     

50例原发性肝癌中医药介入干预状况与生存期关系分析

目的 探讨原发性肝癌中医药介入干预状况与生存期的关系。方法 回顾安徽省立医院中医肿瘤科收治的50例原发性肝癌患者,统计中医药介入干预起点、持续时间及患者生存状况。结果 50例原发性肝癌患者自主选择中医药干预介入治疗时,36例处于D期,4例处于C期,3例处于B期,7例未选择中医药治疗。平均KPS评分为71分;中医药干预时间共323个月,平均干预时间6.46个月;中医药干预起点与患者生存期无相关性（P>0.05）,而中医药干预时长与患者生存期呈显著正相关（P<0.05）。结论 原发性肝癌患者中医药介入干预时临床分期普遍较晚,生存状况有所下降;中医药干预起点与患者生存期无相关,其干预时长与患者生存期呈正相关。     

“重建中气”中药复方对进展期胃癌患者生存预后影响的队列研究

目的 观察“重建中气”中药复方对进展期胃癌术后及辅助化学治疗后患者生存期的影响。方法 回顾分析62例进展期胃癌患者的临床资料,根据是否服用“重建中气”中药复方将其分为中药暴露、无中药暴露两个队列。中药暴露组以“香砂六君子汤”为主方辨证加减。观察性别、年龄、首次就诊体质量和体质量指数（body mass index,BMI）、卡氏功能状态（Karnorfsky performance status,KPS）评分、复发或转移、中药暴露等因素对进展期胃癌生存期的影响。结果 对62例患者随访2年,与无中药暴露组比较,中药暴露组患者体质量和BMI显著升高（P<0.05）,复发或转移率显著降低（P<0.05）;Kaplan-Meier单因素生存分析结果显示,中药暴露、基线KPS评分、复发或转移、基线BMI是生存期的影响因素（P＜0.05）;COX多因素回归分析显示,KPS评分是总生存期的独立影响因素。结论 进展期胃癌术后患者为口服中药的优势人群,“重建中气”中药复方可增加或稳定进展期胃癌患者的体质量,提高患者生存质量,改善预后生存。     

The Untimely Stevie Smith

Abstract

This essay considers the role of the untimely in the work of Stevie Smith. It explores motifs of belatedness in her reception history, suggesting how her own authorial persona and public presentation encodes this response. It examines the notion of the last-minute in her work, focusing on motifs such as disruption, elongation and delay. It suggests how her revision practice responded to the idea of being ‘too late’, with the moment of publication providing her with further prompts to revise her work. It focuses on final words and endings in her poetry and frames her interest in Christianity through ideas of temporality and form.     

What Kind of Security Concept Does Our World Need?

While the threat of war has decreased,there have appeared intricate security issues that affect all aspects of human life,breaking through various defenses and threatening the well being of all actors in the contemporary world,including nations,groups and individuals.This risky situation calls for a new security concept,one that transcends traditional state centrism,national supremacy and coercion.The new security concept,which should assimilate the general theory of grand strategy,focuses on a vision that spans time and space,valuing humankind as it exists as one of the dynamic factors of nature and society.The essentials of the new security concept are to recognize balanced development as the substance of security and to govern national strength and the application of means and tactics.It aims at realizing comprehensive security across various social fields within states,to achieve mutual security among national,international and individual actors,as well as harmony between man and nature,continuous security leading to lasting and universal peace in the future.
