Key functions of civil society organizations (CSOs) are to criticize governments and to hold them to account. Recent trends of privatization and contracting out challenge CSOs’ opportunities to voice such criticism. The purpose of this article is to analyse whether and why CSOs ‘hold back their criticism’ of public authorities, and how a compromised advocacy can be linked to financial, organizational and institutional factors. The article draws on an original survey of 2678 Swedish CSOs. The analyses show that certain levels of funding make CSOs more likely to hold back in their criticism, but also organizational and institutional factors play a role. The results identify the importance of distinguishing between objective and subjective factors related to how dependency is framed. It is the felt needs, experiences and perceptions of CSOs themselves that make hem prone to the strategic choice to hold back criticism of public authorities.  相似文献

In this work, we intend to evaluate the triangular sustainability of not-for-profit organizations, putting a special emphasis on the study of economies of scale. After a collection of raw data from the historical archives of the institution (a ‘Santa Casa da Misericordia de Barcelos’), we constructed a panel database. Using this database, we estimated cobb-douglas costs functions, by applying fixed and random effects. We found that Portuguese institutions as the one here studied (belonging to the Portuguese Social Economy and as a representative of the Holy Houses of Mercy) exhibit economies of scale, which ask for a renewed perspective of the sector by the regulating entities.  相似文献

Training on commercial sexual exploitation (CSE) and victimization of lesbian, gay, bisexual, transgender, and queer (LGBTQ) youths can increase awareness among professionals who provide services to this community. This study evaluated the effectiveness of a community-based training program geared toward mental health workers in a diverse metropolitan city. The training provided information about the continuum of sexuality and gender identity, sensitivity when working with LGBTQ clients, LGBTQ clients’ risks for CSE, and ways to improve service delivery to this population. Participants’ (N?=?64) knowledge level of these areas was examined prior to the training, immediately thereafter, and in a six-month follow-up. Participants showed an increase in knowledge from pretest to posttest. Follow-up testing on a limited sample revealed scores that were lower than posttest scores, but higher than pretest scores. Overall, through this community-based training, participants gained knowledge about the continuum of sexual and gender identity, appropriate service delivery when working with LGBTQ individuals, and the risk factors for CSE for LGBTQ youths. Participants also reported feeling satisfied with the training approach and format. Implications for future training to enhance mental health workers’ competence with LGBTQ victims of sexual exploitation are explored.  相似文献

This investigation approaches the levels and the predictors of loneliness among migrant youths from returned migrant families from France to Portugal. Three research questions guided the study: (1) Does loneliness of migrant youths differ from those who have never migrated? (2) Are migrant youths’ re-acculturation factors related to their loneliness? (3) Is the adaptation of migrant youths linked to their loneliness? The answer to these questions is important to improve migrant youths’ re-acculturation experiences and their adaptation. The sample included 222 youths from returned migrant families from France. Participants completed the brief Portuguese version of the Revised UCLA Loneliness Scale (ULS-6), in addition to measures of re-acculturation and adaptation. A control group comprised of 211 Portuguese adolescents who have never migrated was also involved in the investigation. Youths from returned migrant families showed lower levels of loneliness than their native Portuguese counterparts who have never migrated. Demographic, re-acculturation, and adaptation factors were significantly related to adolescents’ loneliness. Major predictors of loneliness were age at return, contacts with peers without migratory experience, perceived discrimination, stressful adaptation experience, and satisfaction with life.  相似文献

This study was conducted in a nursery for eucalyptus seedling production in a forest Company, located in the southern state of Bahia, Brazil. It aimed to evaluate the ergonomic conditions of the preparation of cuttings and mini-cuttings with scissors for Eucalyptus seedling production to increase well-being, satisfaction and safety and minimizing the occurrence of occupational diseases, also improving the process efficiency and final product quality. Environmental conditions, levels of noise, postures, RSI risk and physical workload were assessed. The environmental conditions complied with the recommended norms, except at certain times of day, when workers should make compensation breaks. The workers that collect minicuttings presented postures classified as normal by OWAS. On the other hand, the posture of workers dealing with cutting preparation requires corrections in a short run. The workers were subjected to moderate RSI risk due to the high degree of repeatability found. The physical workload was classified as mild, with no need for ergonomic interventions.  相似文献

Ergonomics for Eletrobras arose from the need in having an environment more suitable to the characteristics and circumstances of employees, in compliance with Regulation Standard no. 17 - Ergonomics (NR17) of the Ministry of Labor and Employment. Being a mixed economy company with regionalized anthropometric characteristics of its employees, the study of ergonomic adjustments and improvement of the concept of Ergonomics were and have been of great importance to the company's production environment. These advances have contributed to the development of specific technical criteria for the purchase of furniture and work tools (accessories), apart from their possible effects on the user. Ergonomics has been perceived as a technical-scientific tool, aimed to study labor interactions, new technologies and specific characteristics of the activities performed. To meet these demands a multidisciplinary Ergonomics Committee was created in Eletrobras, and effectively established the Ergonomics Management Program in the company; This program is marked by well-defined phases with great success in making use of these studies for other types of corporate activities and also facilitating the program control and its maturity levels, even at a business level.  相似文献

The environment where everyday activities are developed, these should be appropriate and the individual who will execute them, for greater efficiency of their work and even if you feel safe, comfortable and satisfied when interacting with that space, expending less energy to this interaction. Given this context, this study aims to structure a software with the results obtained in the field, from anthropometric measure to subsidize the furniture industry in manufacturing of furniture, definition work situations, considering the different anthropometric measurements made between 2001 and 2010, using data from this sample of adults aged 18 to 65 years old and children between 6 and 11 years old. It was convenient to make the software with a site, only instead of staying on the Web has been recorded on CD Rom. Tests with the prototype allow navigation through the structure of the software. The data needed to implement the remaining modules were also raised. Issues related to system layout and usability of the interface also were not considered, because it is an initial prototype.  相似文献

Companies have increasingly sought strategies that will ensure a more competitive position in the marketplace. Among these strategies adopted by companies include the health and welfare of the worker, factors currently valued by consumers, especially those of most demanding market. Thus, the postural analysis is of great importance and interest because it is the study of positioning related to body parts like head, torso and limbs, capable of producing loads that may be excessive or insufficient causing disturbances in the muscle skeletal system worker. The aim of this study was to perform a postural analysis of the main sectors of workers (slaughter, cutting room, special cuts, packaging and dispatch) of a typical refrigerator pig industry in Brazil during the execution of their daily activities as well as developing proposals to minimize and/or eliminate the diseases and accidents. The study followed the safety norms of Brazilian Ministry of Labor and Employment. The posture analysis used the OWAS (Ovako Working Posture Analyzing System) methodology. The postures assumed by workers in the sector of packaging were as the most in need of emergency and quick action.  相似文献
