ABSTRACT

On 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

This paper addresses gender differences in the social capital of entrepreneurs in a developing country. Social networks are often an important asset for accessing resources; however, they may also be a liability in developing countries, since entrepreneurs are often expected to support their contacts. Using a recent survey among urban and rural Ugandan entrepreneurs, we focus on the financial resources that entrepreneurs can obtain from their contacts on the one hand, and requests for financial support made to the entrepreneurs from these contacts on the other hand. Our results show that there are gender differences associated with access to, and requests for, financial resources.  相似文献

习近平“不忘初心、牢记使命”重要论述的生成具有多重逻辑。马克思主义关于无产阶级政党的理论、中国共产党以人民为中心的思想内核是其理论渊源;中国传统民本思想的精髓、以红船精神为源头的革命精神是其文化根基;人民对美好生活的向往、新时代中国特色社会主义任务的严峻性、解决“三个如何”之问的迫切性是其现实要求。  相似文献

In the change management literature, most studies on recipients' resistance to change include only the views of agents or of recipients, thereby ignoring that these parties may have different perceptions. In this quantitative study, we include the perceptions of both parties in studying the recipients' resistance and the impact of the agent's leadership behavior. In a sample of 117 agent-recipients groupings, covering 110 different change projects in 90 organizations, we found that agents perceive higher levels of recipients' resistance than do the recipients themselves. Additionally, we found that agents who create space to enable recipients to think and act differently (by employing creating behavior) report higher levels of recipients' resistance, whereas recipients perceive their resistance to be lowered when agents facilitate an emotional connection to the change (framing behavior). The depth of the change appeared to moderate the relationship between agent's leadership behavior and recipients' resistance, indicating that agents and recipients differ in which change leadership behaviors they perceive as increasing or decreasing resistance at different levels of change depth. These findings imply to reconsider the relationship between agent and recipients and we propose some promising avenues for future studies in resistance research.  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

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 aim of this research was to adapt and validate the Concern with Acting Prejudiced (CAP) scale for a Spanish sample. This measure evaluates concern about appearing prejudiced to others or oneself and the motivation not to deviate from personal egalitarian standards. First, we completed the translation and an item content validity analysis. Then, in Study 1 (N = 198), we conducted an exploratory factor analysis. In Study 2 (N = 383), we conducted a confirmatory analysis of the unifactorial structure of the Spanish version of the scale and examined its validity. In Study 3 (N = 89), we explored the moderating role of participants’ concern with acting prejudiced in the relation between implicit prejudice and explicit prejudice. The results confirmed the unifactorial structure of the scale, its appropriate psychometric properties and its predictive validity. Moreover, we confirmed that the CAP moderated the relation between implicit and explicit prejudice. In participants with a low concern with acting prejudiced, implicit prejudice was positively related with modern prejudice; in participants with a high concern with acting prejudiced, these variables were not related.  相似文献

The study surveyed 506 employees in the United States to test the effect of internal communication (i.e., corporate-level symmetrical and leadership-level responsive communications) on fostering a positive emotional culture characterized by companionate love, joy, pride, and gratitude. In addition, we tested the interplay between corporate internal communication and a positive emotional culture and its influence on supportive employee behaviors, specifically, organizational citizenship behavior (OCB) and employee advocacy. Results indicated that symmetrical communication and responsive leadership communication cultivated a positive emotional culture in organizations. Such culture also fostered employee OCB and advocacy. Moreover, corporate symmetrical communication directly and positively influenced employee OCB. Finally, this study found that employee OCB positively affected employee advocacy. The theoretical and practical implications of the findings for public relations scholars and practitioners were discussed.  相似文献
