Despite the historical highs for age at first marriage, little is known about the causal relationship between marriage delay and wages, and more importantly, the mechanisms driving such relationship. We attempt to fill the void. Building on an identification strategy proposed in Dahl (Demography 47:689–718, 2010), we first establish the causal wage effects of marriage delay. We then propose ways to distinguish among competing theories and hypotheses, as well as the channels through which marriage delay affects wages. Specifically, we take advantage of their different implications for causal relationship, across gender and sub-populations. We reach two conclusions. First, we find a positive causal impact of marriage delay on wages, with a larger effect for women. Comparison of IV and OLS estimates suggests that the observed relationship between marriage delay and wages is attributed to both selection in late marriages and true causal effects. Second, we find strong evidence that the positive, causal effects are almost exclusively through increased education for both men and women.  相似文献

在民族学调查中,经常会涉及舅权问题.这种习俗一度被认为是同母系制联系在一起的,是母系制的产物,如果出现在某一父系民族,就证明该民族曾经历过母系制阶段.但民族学研究也证明舅权并不就是母系社会的必然产物,在父系社会中仍然有其存在的社会根源.因为在所有的社会中,亲属关系都必须是双边的,个人既通过父亲与一些人相联系,也通过母亲与另一些人相联系,即使是在最牢固的父系制社会中,母系亲属也受到一定的重视,这种重视往往通过舅权表现出来.换言之,在父系社会中,父系宗亲与子女的权利义务关系是主要的,但母系亲属与外甥也保持一定的权利义务关系,而且非常必要.  相似文献

Evaluating and quantifying human suffering in humanitarian operations offers an innovative and potentially powerful way to assess the performance of humanitarian logistics (HL) and help build optimization models. Previous studies have suggested deprivation cost as a metric and have estimated deprivation cost functions for water using willingness‐to‐pay. Our study proposes deprivation levels, defined as the degree of human suffering caused by lack of access to a good or service, and estimates deprivation level functions using a numerical rating scale. Analyzing data collected from respondents with and without disaster experience, we find that individuals in the latter category estimate deprivation differently from the beneficiaries of disaster relief. Our study demonstrates that deprivation levels can be expressed as logistic growth functions with a typical S‐shape, and that these can be integrated into HL optimization models to better account for human suffering.  相似文献

Deepening reform, promoting the rule of law, and implementing the “Five Develop ̄ment ” concepts have had a deep influence on the modernization of governance in ethnic autonomous regions. Based on a review of 30 years of success ̄ful experiences in implementing ethnic regional au ̄tonomous law, and focusing on the concepts of“innovation, coordination, green development, openness and sharing”, we need to conduct in -depth research on the ways to:promote governance by law, realize the modernization of governance;and promote the efficient implementation of ethnic autonomous systems in the ethnic autonomous re ̄gion.
The 155 ethnic autonomous areas of China cover 64% of the total area of the country. There ̄fore, the governance of the country cannot be a ̄chieved without modernizing the governance in the ethnic autonomous regions. Modernizing the gov ̄ernance in ethnic autonomous regions is a necessa ̄ry element for modernizing the governance of the nation. The modernization of the ethnic autono ̄mous regions actually means the legalization of the governance in ethnic autonomous areas, which is a main part of the legalization of the ethnic affairs.
The comprehensive, deepening of reform, and promoting governance by law have been strongly promoted. We should start from reality, respect differences, and take the development concepts of“innovation, coordination, green, openness and sharing” into consideration so as to promote the ef ̄ficient implementation of ethnic regional autono ̄mous systems through various methods. We should update our concepts, weaken specificity, solidify locality, intensify new thinking, innovate the run ̄ning of ethnic autonomous systems, and promote the modernization of governance in ethnic autono ̄mous regions. Based on a comprehensive analysis of the theories and practices used since the imple ̄mentation of ethnic regional autonomous regula ̄tions, and under the premise of intensifying “the legalization of ethnic affairs”, we should deepen the comprehensive reform of the ethnic autonomous regions, comprehensively promote the governance by law, and realize the goal of building a moder ̄ately prosperous society as scheduled through im ̄proving and innovating the running of ethnic re ̄gional autonomous systems.
“Ethnic areas are districts with rich resources and water sources; they are ecological screen zones, cultural characteristic zones, border areas, and poor areas.” At the same time, due to histori ̄cal, social and natural factors,“the natural condi ̄tions of most ethnic areas are not good; their be ̄ginning phase of development is low; they have many historical debts; they are located far away from the central markets and urban areas;their ur ̄ban-rural gap is very obvious”, and “their gap with the eastern areas ( of China) is growing larger and larger”. The reform and the promotion of gov ̄ernance by law in ethnic autonomous areas should put more emphasis on locality, ethnicity and “au ̄tonomy”. Of course, we must avoid of “artificial ̄ly” intensifying ethnic consciousness, and creating ethnic “differences”. Meanwhile, we should “im ̄prove the capability for legal management of ethnic affairs”, “intensify the construction of laws and regulations related to ethnic work”, “legally han ̄dle those issues involving ethnic factors”, “insist on resolving issues involving ethnic factors by the law, and avoid of regarding civil and criminal problems related to ethnic people as ethnic prob ̄lems, or regarding common disputes in ethnic are ̄as as ethnic problems. ”
We should affirm that China’s ethnic relations are harmonious, and that their economics are de ̄veloping rapidly. Since the implementation of the policy of “reform and opening -up”, especially since 2005 , the economics in ethnic autonomous regions have developed dramatically; the people’s living conditions have continuously improved;bas ̄ic infrastructure has significantly speeded up; and ecological protection has solidly improved. Howev ̄er, the problems still prevail. For example, the poverty in ethnic areas is still serious—there are more than 25 million poor in ethnic rural areas. Therefore, the task of poverty alleviation is still very tough. In addition, the gap between urban and rural areas and between different regions is very large in ethnic autonomous regions. Finally, the rate of urbanization is very low.
In sum, during the process of modernizing so ̄cial governance in ethnic autonomous regions, we must pay full attention to the five“stage character ̄istics” of ethnic work in China which are the:( i) co - existence of opportunities and challenges brought by the “reform and opening -up” policy and the socialist market economy;( ii) co-exist ̄ence of the state’s constant support to the ethnic ar ̄eas and its low level of development; ( iii ) co -existence of the state’s constant support to the eth ̄nic areas and the weak level of basic public service capability in ethnic areas; ( iv ) co -existence of the constant exchange and fusion between various ethnic groups and the disputes involving ethnic fac ̄tors;and ( v) co-existence of the great achieve ̄ments in anti-national splittism, religious extrem ̄ity, and violent terrorism, as well as the active ter ̄rorism activities in some areas. Only when we rec ̄ognize this situation, can we understand the speci ̄ficity of doing ethnic work in China. The innova ̄tion of governance of ethnic autonomous areas and the promotion of governance by law in the whole country must start from this actual situation.
At present, we still need to clarify the conno ̄tations of autonomous rights. Based on a clear clar ̄ification of the basic meaning of ethnic regional au ̄tonomous rights, we should deepen reform, active ̄ly transform the governance of the ethnic autono ̄mous regions, further deepen relevant theoretical studies, and positively promote the ethnic regional autonomous system. The main purpose of the eth ̄nic regional autonomous areas is to promote the de ̄velopment of the various affairs of ethnic minorities and ethnic regional autonomous areas. The purpose for improving the ethnic regional autonomous sys ̄tem is to ensure the development of ethnic minori ̄ties and ethnic regional autonomous regions. Im ̄proving the ethnic regional autonomous system should transform from one of preferential treatment to one of nuanced development.
Looking back to the past, the legal construc ̄tion of ethnic regional autonomy has made great a ̄chievements. However, the preferential policies of the state and relevant institutes are still the real factors promoting the development of the various af ̄fairs of the ethnic minorities and ethnic autonomous areas. As described in this article, there are multi ̄ple factors which influence the efficiency and per ̄formance of the ethnic regional autonomy. The eth ̄nic autonomous regions are restricted by natural conditions and economic development, therefore, they have to depend on assistance from the state and the relevant institutes—this is the objective re ̄ality. However, the improvement of the ethnic re ̄gional autonomous system must change the status of the past, and enable the ethnic regional autono ̄mous system play out its actual role so that the va ̄rious affairs of ethnic minorities and ethnic autono ̄mous regions can step onto a road of nuanced de ̄velopment.
The future development of the ethnic regional autonomous system depends on the consensus of theoretical and practical circles, i. e. a long-term mechanism whose purpose is to enable the system itself play its actual role should be established. Only by such a mechanism, can these puzzling problems be solved and gradually improved. Tak ̄ing the breakthrough of the actual effect of the sys ̄tem as the starting point of the ethnic regional autonomy’s deepening of the reform, one should take the following aspects into consideration:1 ) re-examine existing laws and regulations, and im ̄prove them on the basis of institutional norms, en ̄hance normalization, uniformity and manipulability of the ethnic regional autonomous regulations; 2 ) sort out the relationship between the institutions in ethnic autonomous areas and the upper levels of the state institutes, as well as the relationship be ̄tween the institutions on the same level;on the va ̄rious institutional levels, enhance clear cognition on the position, role and organizing principles of the ethnic regional autonomous system, and avoid taking the ethnic regional autonomous system as the affairs of the ethnic autonomous areas;3 ) im ̄prove the supervisory mechanisms for running the ethnic regional autonomous system; and 4 ) im ̄prove the mechanisms for handling disputes on the running of the ethnic regional autonomous system.
We must work closely, share the achieve ̄ments, and promote the operation of the ethnic re ̄gional autonomous system. For this purpose, we should:1 ) standardize the management of the eth ̄nic regional autonomous system, and weaken the“specificity”;2 ) promote the governance capabili ̄ty of the ethnic regional autonomous areas, and so ̄lidify the concept of“locality”;3 ) enhance auton ̄omous awareness and capability, intensify “new thinking”, motivate initiatives from the autonomous areas, and improve the autonomous system from the bottom-up, and rationally allocate the power and rights of the high-level organs and the auton ̄omous organs in the ethnic autonomous areas.  相似文献

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
