This study examined the effectiveness of several financial strategies for nonprofit organizations in fighting the Great Recession. Using data from human services and community improvement organizations in the state of New Jersey, we tested hypotheses about the relationships between three measures of financial sustainability and various fundraising efforts and financial indicators. We found that (1) except for strong external funding relationships, funding efforts were generally not effective in enhancing financial sustainability during the crisis; (2) higher operating margin and equity ratio improved an organization's ability to generate revenue and maintain expense levels, but higher debt ratio and administrative cost ratio were generally harmful; and (3) revenue diversification might aggravate fiscal stress and cause more expense cuts in a severe crisis. These findings improve our understanding of the mechanics of nonprofit management during times of harsh fiscal conditions and suggest useful ways for nonprofit organizations to navigate future financial crises.  相似文献

Objective: The aim of this study was to analyze the age-related recession trajectory of reproductive health indices in middle-aged and elderly Chinese men.

Methods: A population-based cross-sectional study was conducted in Jiashan County, Zhejiang in 2012. Healthy men between 40 and 80 years of age were considered eligible for the study. Physical examination and the sex hormones were measured. The subjects were assessed based on the 5-item version of the International Index of Erectile Function (IIEF-5) for Erectile Dysfunction (ED), and Aging Males’ Symptoms (AMS) scale for Symptomatic Late-Onset Hypogonadism (SLOH).

Results: TG showed a decrease at age 60 years. Testis volume and TT did not show significant difference among the four age groups; cFT began to decrease at age 50 years and Bio-T decreased faster at age 50 years. SHBG and LH increased faster at age 50 and 70 years, respectively. IIEF5 score decrease faster at age 60 years. AMS scores increased faster at age 70 years. With the increase in age, the symptoms of ED and SLOH became severer.

Conclusion: Different indices on reproductive health of men showed turning points at different ages. At first, androgenic sex hormones decreased faster, and then erectile dysfunction got severer, and the last overall male syndromes declined.  相似文献

The aim of this study was to investigate the manner in which teachers facilitate the pedagogical process within a culturally diverse student population. The study focused on two primary schools in China; one located in a more fully developed city in eastern China (Case A), while the other was in a less developed city in rural western China (Case B). This allowed the researchers to compare and analyse the different instructional practices by means of semi-structured interviews and questionnaires. The findings indicate that: the teachers in Case A demonstrated overall affirmative attitudes towards ethnic minority cultures, as well as towards the students belonging to those cultures. However, the teachers also chose not to mention the specific ethnic identities and cultural differences of the students during the course of their instruction in order to ensure equal treatment for everyone. This leads to a kind of ‘cultural blindness’ in the classroom. In Case B, opinions regarding minority cultures were more varied. Compared with the teachers in Case A, more teachers in Case B found minority cultures to be inferior to the dominant Han culture. Some teachers also, counter intuitively, were of the opinion that the minority cultures were even superior. At the instructional level, school leadership developed courses on local culture and ethnicity for the teaching staff. This was done for a variety of reasons. The strongest evidence to support culturally responsive teaching in Case A does not stem from teaching and learning demands but from the necessity to pursue characteristics that make them distinctive from other schools at the same time, Case B’s practice of culturally responsive teaching was strongly supported by the government and UNICEF. Teachers in both schools indicated that they had integrated their knowledge of ethnic minority groups into the subject matter when it was necessary.  相似文献

Research on domestically violent men typically takes an oppositional logic of gender. While the significance of class in researching domestically violent men is identified, class and gender are often treated as separate entities that do not complicate each other. Drawing upon group observations and in‐depth interviews, this paper identifies how intersections of class and gender manifest in the counselling experiences of domestically violent Taiwanese men. From a Bourdieusian feminist analysis, the authors analyse (1) how class distinctions serve to (re)produce gendered hierarchy; (2) how contradictory experiences of gender reveal a relational understanding of class; and (3) how the gendered nature of domestically violent men is inscribed with a meaning of (working) class specificity for maintaining middle‐class ‘purity’. In analysing men's multiple and conflicting experiences, this paper contributes to research on domestically violent men by showing how class and gender are actively constructed and not produced in a monolithic/invariant way.  相似文献

The purpose of this paper is to examine the influence product-harm crisis situations have on, a firm's spokesperson strategies in China's emerging market economy. Through the content analysis of, 127 product-harm crises, crisis type is found to be a predictor of spokesperson strategies. Compared, with Chinese brands, foreign brands are less likely to employ top-executive spokesperson strategies, during product-harm crises. Crisis severity was found to have no impact on the adoption of, spokesperson strategies.  相似文献

医疗保险制度改革是哈萨克斯坦医疗改革的重要组成部分。独立以后,在全民免费医疗无法维持的情况下,哈萨克斯坦政府先后实施了强制医疗保险制度和自愿医疗保险制度。然而,这两种医疗保险制度的运行效果远远没有达到政府和民众的预期。目前,哈萨克斯坦又出现了恢复强制医疗保险制度的倾向。纵观哈萨克斯坦医疗保险制度的发展过程,可以认为,这种改革缺乏持续性的政策和明确的目标。另外,如何妥善解决社会公平和效率之间的关系,以及转变民众的医疗卫生观念,是未来哈萨克斯坦医疗保险改革亟待解决的深层问题。  相似文献
