From chavela to frida: loving from the margins

This article analyzes the portrayal of lesbian desire in the case of two of the most renowned icons of contemporary Mexican and Latino popular culture: singer Chavela Vargas (1919-2012) and painter Frida Kahlo (1910-1954). This article explores the intertextual dialogue between two texts that deal with the construction of Kahlo's persona and sexuality: Chavela's memoir, titled Y si quieres saber de mi pasado (2002), and the film Frida (2001), directed by Julie Taymor. Fundamental to this study is Chavela Vargas' lesbian subject position in both texts and the consequences and implications her location has in representing lesbian homoerotics and desire.     

西方发达国家的家庭政策及对我国的启示

西方国家早期的家庭政策是通过普适性的福利性手段减少家庭贫困,全面提高公民的福利水平。20世纪60、70年代,西方国家完成人口转变之后,家庭的发展进入后现代化时期,家庭模式发生了巨大转变。为达到国家的人口战略目标,西方国家的家庭政策从覆盖全民的福利性保障,逐渐转为在保证福利的同时,更加注重鼓励生育。当前西方国家在家庭政策的实施中所采取的主要政策工具包括家庭补贴和税收优惠政策,产假、生育补贴和工作保护,以及儿童看护和教育政策。依据西方发达国家家庭政策的已有经验,我国家庭政策体系可以采取"保基本、广覆盖、福利与调控人口并重"的政策路线。     

基于Logistic回归分析的土地利用变化空间统计与模拟

运用二元Logistic回归分析的方法,对研究区域土地利用/覆盖变化有重要贡献的10种驱动因子进行空间统计分析,并用ROC方法对所有回归模型的拟合优度进行了检验,运用GIS软件绘制研究区土地利用格局空间分布的经验统计概率图。ROC检验结果显示:各种土地类型的拟合度分别为耕地0.761,林地0.844,草地0.673,水域0.859,建设用地0.937,拟合度均大于0.5,拟合度较好;研究结果揭示了距县城中心的距离(X2)、高程(X6)、坡度(X7)、坡向(X8)、人口密度(X9)因素对研究区土地利用格局形成与演变有重要决定作用,为进一步研究黄土高原地区未来的土地利用动态变化情景奠定了基础,同时也为该地区的土地利用管理提供了科学依据。

Welfare and Redistributive Effects of Social Assistance in the Global South

This paper presents an analysis of the recent evolution of social assistance in the developing world, looking at its complex typological configuration, which has interlinked with, and partly reflects the complex demographic and epidemiological transitions and rapid urbanization and economic convergence that many developing countries have exhibited over the past decades. The paper underscores the principles of the poverty focus of social assistance and presents an overview of existence evidence of first‐ and second‐order effects of social assistance, particularly in the domains of poverty, education, health, and labor markets. Moreover, the paper highlights the knowledge gaps with regard to the longer term and gender‐specific welfare effects of social assistance, and the redistributive effects, and the incentives and distortion mechanisms that transfer programs can generate in the labor and insurance markets.     

History,Evolution and Future of Big Data and Analytics: A Bibliometric Analysis of Its Relationship to Performance in Organizations

Big data and analytics (BDA) are gaining momentum, particularly in the practitioner world. Research linking BDA to improved organizational performance seems scarce and widely dispersed though, with the majority focused on specific domains and/or macro‐level relationships. In order to synthesize past research and advance knowledge of the potential organizational value of BDA, the authors obtained a data set of 327 primary studies and 1252 secondary cited papers. This paper reviews this body of research, using three bibliometric methods. First, it elucidates its intellectual foundations via co‐citation analysis. Second, it visualizes the historical evolution of BDA and performance research and its substreams through algorithmic historiography. Third, it provides insights into the field's potential evolution via bibliographic coupling. The results reveal that the academic attention for the BDA–performance link has been increasing rapidly. The study uncovered ten research clusters that form the field's foundation. While research seems to have evolved following two main, isolated streams, the past decade has witnessed more cross‐disciplinary collaborations. Moreover, the study identified several research topics undergoing focused development, including financial and customer risk management, text mining and evolutionary algorithms. The review concludes with a discussion of the implications for different functional management domains and the gaps for both research and practice.     

New MNE subsidiaries in old clusters: when,why, and how

Despite the rise of globalization, industrial clusters remain vibrant spaces for the generation of knowledge and innovation. Aware of this reality, multinational enterprises (MNEs) seek to reconcile the advantages of international operations with the specific endowments of individual territories. By studying the case of the Inditex subsidiary in the Vinalopó footwear cluster, this research shows how the creation and activity of a specialized subsidiary and the evolution of the industrial system interweave. The study shows that, rather than agglomeration per se, access to specific resources guides location as the cluster matures. Furthermore, local embeddedness shapes post-entry dynamics at the micro and meso levels. Autonomous decisions boost the subsidiary’s access to local networks and the exploitation of cluster advantages, aiding the resilience of the cluster by contributing extra-cluster knowledge.     

Shiftwork tolerance and 24-h variations in moods

Abstract

The objective of the study was to identify the differences in 24-h variations in moods between three groups of oil-refinery workers: tolerant shiftworkers, intolerant shiftworkers and workers who had never worked in shifts. Each group comprised 29 workers matched by age. The mood measurements were taken during a 24-h period every 2 h starting from 08:00 h. Results were scored for three scales: positive moods, negative moods and fatigue. The two-factor ANOVA revealed the significant main effect of groups for all three moods indicating differences at the average level of 24-h variations in all moods between workers who differed in the degree of tolerance to shiftwork. The significant main effect of time of day was also found for all moods while the reliable interaction between groups and time of day was observed for negative moods only, indicating a different shape of 24-h variations for non-shiftworkers in comparison to shiftworkers.     

Sleep and napping in young shiftworkers: A 5-year follow-up

Abstract

The present study examined sleep characteristics in young workers who entered rapidly rotating shiftwork for the first time and stayed on shifts for 5 years. Data were collected when the subjects had shiftwork experience of approximately 1.5, 3.5 and 5.5 years and a mean age of 22, 24 and 26 years. Data are presented showing significant differences in the main sleep durations between situations within the shift cycle and a small reduction in overall sleep over the observed period, primarily due to a sleep reduction on afternoon shift days. Data on sleep quality did not show any change over this early period of shiftwork exposure. In addition, napping strategies did not change, with the exception of a small increase in those taking naps on night-shift days between 1.5 years and 3.5 years of shiftwork exposure. At all the observed phases there were more young shiftworkers taking a nap on the morning shift days than on the night-shift days. The data suggested that reduced sleeps on morning and night-shift days were not compensated by taking a nap, but rather with an increase in main sleep duration on afternoon shift days and days off. A weak tendency for individuals to be relatively long or short sleepers irrespective of sleep conditions could be seen.     

碳预算方案：一个公平、可持续的国际气候制度框架(英文)

全球温室气体减排已有一定的科学认知和国际政治意愿。由于涉及经济代价和发展权益,全球温室气体减排的国际制度框架均难于兼顾公平与可持续性双重目标。以气候安全的允许排放量为全球碳预算总量,设为刚性约束,可以确保碳预算方案的可持续性;将有限的全球碳预算总额以人均方式初始分配到每个地球村民,满足基本需求,可以确保碳预算方案的公平性。根据历史排放和未来需求进行碳预算转移支付,设计相应的资金机制,使碳预算方案具有效率配置特征。不同于分时段、临时目标的《京都议定书》途径,这样的碳预算方案是一个全面涵盖的整体性一揽子方案。然而,由于气候变化问题已泛政治化,许多技术性问题需要国际政治与外交谈判才能解决。
