ABSTRACTOn 20 September 2017, Hurricane María made landfall on Puerto Rico causing unprecedented disaster. From that day onwards, the Puerto Rican multi-layered colonial, social and political context was further complicated by the traumatic acceleration of a human disaster via this natural disaster. This crystalized the urgency of using art as vehicle for (social) catharsis, a practice that continues to be used by individual artists, collectives, community organizations, art projects, and other art institutions on the island and abroad, through mural art, community paintings, art exhibitions, literature, music, and many other aesthetic expressions. This article examines, from a decolonial and critical cultural studies perspective, post-Hurricane María artistic expressions in contemporary art as decolonial aesthetics through the cathartic use of the frame of an aesthetics of disaster. It is argued that, an aesthetics of disaster aims to re-assert an artistic form that is able to accelerate the discursive nullification of a deeply rooted colonial, social and cultural problem by way of art as catharsis inspired by the way that Hurricane María unveiled these problems. The piece briefly contextualizes Puerto Rico, and it examines the idea of Puerto Rican contemporary art as catharsis. Then, it describes how Puerto Rican contemporary art exhibitions and associated aesthetic production are processing urgent post-hurricane issues through three illustrative pieces in exhibitions in PR and abroad in the United States (US). Lastly, decolonial aesthetics is reexamined and re-understood, informed by Édouard Glissant's view expressed in Poetics of Relation which aids to the conclusion that Puerto Rican contemporary art using the frame of an aesthetics of disaster functions as a powerful form of decolonial aesthetics. 相似文献

Background
The rates of breastfeeding worldwide are slowly improving since 1996. Europe is still trailing behind the global breastfeeding incidence and prevalence rates. Thus, breastfeeding promotion, protection, prolongation and support have become an important challenge as breastfeeding sharply decreases in the first six months of life.Objectives
The aim of this project is to determine, assess and identify the real impact of breastfeeding support networks in Murcia (Spain).Methods
After searching unsuccessfully for a validated questionnaire, a specific one was developed and validated for measuring the impact of formal and informal support networks through five dimensions: satisfaction, consultation, experience, problems and support. The questionnaire was provided to 500 mothers with experience in breastfeeding, who brought their children to baby paediatricians between 2 June and 27 November 2014. Upon completion of the survey and fieldwork, a detailed statistical analysis was conducted.Results
The degree of satisfaction perceived by the users of the services of support breastfeeding networks is remarkable. In addition, mothers who clarified their doubts and discussed their problems with health professionals and/or breastfeeding support networks were more likely to breastfeed for a longer duration compared to those who did not (p = 0.005). Furthermore, mothers who sought support in breastfeeding are more likely to breastfeed for more than 6 months (p < 0.0005).Conclusion
Based on this information, we conclude that breastfeeding support networks have a positive influence in the duration of a women’s decision to breastfeed. 相似文献3.

国家角色模式的演变主要着眼于国家任务的承担及其实现方式的变化,近代以来,国家角色模式经历了从夜警国家到福利国家再到担保国家的三次嬗变。民营化及公私合作的发展促使国家与私主体越来越多地共同承担公共任务,分担了福利国家的给付之累,也促进福利国家模式向担保国家模式转变,其中,行政任务的民营化及公私合作是担保国家模式的主要背景,担保国家理论便是要探讨在民营化及公私合作背景下国家对公共任务的最终落实如何承担担保责任。担保国家与合作国家内涵相近但各有侧重,且均有重大意义。 相似文献

Nearly 5.1 million children younger than age 18 live with at least one undocumented parent, about 7% of the U.S. child population. Between 2010 and 2013, an estimated 300,000 parents of U.S. citizen children were deported. Raising children in the context of deportation risk increases overall parenting stress for undocumented Latino parents. To investigate this and understand the experience of undocumented parenting, the authors interviewed 70 undocumented parents in two Southwest cities from 2012 to 2013. The authors frame their analysis using the lens of the problem of “illegality.” There are three domains of stressors associated with parenting in the context of deportation risk: trapped parenting, threat of family separation, and altered family processes. The authors discuss these findings in the context of the literature on undocumented families and parenting stress and connect these findings to the current sociopolitical context experienced by Latino families in the United States . 相似文献

The discourse of some of the most powerful public figures in today’s world is often incoherent and nonsensical. Incoherent yet authoritative discourse shows that authority does not rest in language but results from non‐linguistic and pre‐textual conditions. The non‐linguistic and pre‐textual conditions are exemplified in an Australian case‐study of a media debate between the Immigration Minister and a refugee, drawing on research by Smith‐Khan (2019a, 2019b). Two such conditions are then examined with reference to academic publics. First, I ask which languages do or do not carry authority, before moving on to speaker identity as a condition of authority. The close association between English and academic excellence has resulted in diminishing the authority of academic publications in languages other than English. The same is true of publications by women and people of colour. I close by reflecting on referencing practices as forms of extending authoritativeness to voices in excluded languages and from excluded scholars in academic publics. 相似文献

中华人民共和国成立70年来,与政治制度变革和政治路线变迁相顺应,前30年的新闻史研究,“革命史范式”占据主导地位,研究队伍人数较少,研究对象局限于无产阶级新闻事业。后40年的新闻史研究,新闻史的学科地位确立,汲取传播学及其他学科理论与方法,“新闻本体范式”兴起,研究范式多样化,中国新闻史学会成立,学术队伍人才济济,学术成果丰硕并走向世界。此后的新闻史研究,须更多负起“资治”“知来”之责,创新研究范式,填补研究空缺,建设中国特色新闻史学。 相似文献

“Chasing” behavior, whereby individuals, driven by a desire to break even, continue a risky activity (RA) despite incurring large losses, is a commonly observed phenomenon. We examine whether the desire to break even plays a wider role in decisions to stop engaging in financially motivated RA in a naturalistic setting. We test hypotheses, motivated by this research question, using a large data set: 707,152 transactions of 5,379 individual financial market spread traders between September 2004 and April 2013. The results indicate strong effects of changes in wealth around the break‐even point on the decision to cease an RA. An important mediating factor was the individual's historical long‐term performance. Those with a more profitable trading history were less affected by a fall in cash balance below the break‐even point compared to those who had been less profitable. We observe that break‐even points play an important role in the decision of nonpathological risk takers to stop RAs. It is possible, therefore, that these nonpathological cognitive processes, when occurring in extrema, may result in pathological gambling behavior such as “chasing.” Our data set focuses on RAs in financial markets and, consequently, we discuss the implications for institutions and regulators in the effective management of risk taking in markets. We also suggest that there may be a need to consider carefully the nature and role of “break‐even points” associated with a broader range of nonfinancially‐focused risk‐taking activities, such as smoking and substance abuse. 相似文献

For the hierarchical Poisson and gamma model, we calculate the Bayes posterior estimator of the parameter of the Poisson distribution under Stein's loss function which penalizes gross overestimation and gross underestimation equally and the corresponding Posterior Expected Stein's Loss (PESL). We also obtain the Bayes posterior estimator of the parameter under the squared error loss and the corresponding PESL. Moreover, we obtain the empirical Bayes estimators of the parameter of the Poisson distribution with a conjugate gamma prior by two methods. In numerical simulations, we have illustrated: The two inequalities of the Bayes posterior estimators and the PESLs; the moment estimators and the Maximum Likelihood Estimators (MLEs) are consistent estimators of the hyperparameters; the goodness-of-fit of the model to the simulated data. The numerical results indicate that the MLEs are better than the moment estimators when estimating the hyperparameters. Finally, we exploit the attendance data on 314 high school juniors from two urban high schools to illustrate our theoretical studies. 相似文献

国际法在长期的实践当中存在着价值理性弱化的困境,价值理性的趋弱使得国际社会忽视国际法在国际治理中的地位,人类命运共同体理念的出世为国际法价值理性的增进带来曙光。当前人类命运共同体理念已初具影响力,国内政策报告已有初步的系统阐述,该理念在联合国决议中多次出现,表明人类命运共同体在为国际法提供"价值指向"方面有极大的发展潜力。人类命运共同体语言系统中的诸多表述对于国际法价值理性的增进皆有启示意义,从内部形态塑造来看,该理念对于"善治"价值中的"合法性""善意遵守"皆有指导性的表述,从外部环境改良来看,该理念可与"合作"价值下的风险防范、角色定位两方面相联结。为确立具备可操作性的国际法价值理性增进路径,中国、国际组织乃至全球国家都需要扮演好相应的角色,为在人类命运共同体指引下增进国际法的价值理性而努力。 相似文献

人类命运共同体构想作为马克思主义中国化的最新理论成果,是在积极反思人类生存现状的基础之上,对世界未来发展形态的一种前瞻性擘画。总体观之,作为“类”存在的人的主体自觉以及马克思主义“类”思想是人类命运共同体构想的逻辑基点, 现代“人类交往”方式的演进与普遍发展是人类命运共同体构想的现实基点,中国传统文化中的“和合”理念是人类命运共同体构想的思想源点。逻辑起点、现实基点与思想源点共同构成人类命运共同体构想的生成之源,对其系统、深入的阐释与审思则是我们学习、领悟、实践这一伟大构想的重要环节。 相似文献
