<冬明历>是明清时代流传较广、影响较大的民间宗教经书之一,其史料价值弥足珍贵.很长一个时期以来,由于<冬明历>的完整版本一直未被发现,因此对于该书的具体内容和性质,学界多有不识,偶有论及者,或失之偏颇,或流入想像和臆测.本文主要以新近发现的抄本<冬明历>为第一手材料,考察了<冬明历>一书的基本结构及其相关问题,并在明末清初民族冲突的大背景下,重点探讨了民间宗教"夷夏之辨"、反清复明、帝王观的流变与满汉混同等相关问题,为更加深入、全面地认识明末清初的民族与宗教问题提供一种新的研究视角. 相似文献

A product has been formally denned as being subject to sudden obsolescence if its lifetime is negative exponentially distributed. Using an approximate model, Masters suggested that the traditional method of incorporating obsolescence cost as a component of inventory holding costs in the economic order quantity (EOQ) model was appropriate-for products subject to sudden obsolescence, provided that the obsolescence cost component was computed properly. Unfortunately, current practice of the EOQ model seriously underestimates the costs of sudden obsolescence. An exact model demonstrating that Masters' model also underestimated true lifetime costs and overestimated the optimal order quantity has been presented. Neither of these models addressed quantity discounts. Furthermore, with their cost-minimization focus, these models fail to identify situations when minimized costs exceed expected revenues. We extend Joglekar and Lee's model to focus on maximizing profits, rather than minimizing costs. This model answers such questions as whether to stock the product at all, whether to accept a quantity discount offer, and what order quantity to use. Numerical examples and sensitivity analyses suggest that Masters' model provides a significant improvement over the traditional model in moving toward true optimality. However, they also illustrate situations where both the traditional and the Masters' model accept a quantity discount that deserves to be rejected and stock a product that should not be stocked. In such situations, it seems important that a retailer uses the profit-maximization model presented here. 相似文献

This study examined the prevalence of workplace flexibility and the mechanisms that allow workplace flexibility to influence turnover intentions through work–family and family–work conflicts and job satisfaction among low‐wage workers in South Korea. Participants included 250 low‐wage workers whose monthly salary was less than 2 million Korean won (approx. $1,900). The study results indicate that low‐wage workers have limited access to workplace flexibility and that workplace flexibility plays a significant protective role in reducing their turnover intention, indirectly by decreasing work–family conflicts and enhancing job satisfaction. This article also discusses the implications of these findings for labor policy and social work practice. 相似文献

South Korea has been experiencing rapid population aging. In an aging society, the need for healthy lives is greater. Two of the fundamental factors to enable independent and active life for the elderly are mobility and social participation. The purpose of this study was to examine the relationship between older adults’ mobility, social participation, and quality of life in South Korea. We used data from the 2017 National Survey of Older Koreans conducted by the Ministry of Health and Welfare and the Korea Institute for Health and Social Affairs and applied hierarchical regression. The major finding was that older adults’ mobility had a positive impact on their life satisfaction. After controlling for older adults’ mobility, social participation was positively associated with life satisfaction regardless of the place of residence. The findings of this study not only make a valuable contribution to further research on mobility and social participation but also provide new insight into improving older adults’ quality of life. 相似文献

The present research examined how school contexts shape the extent to which beliefs about the potential for change (implicit theories) interact with social adversity to predict depressive symptoms. A preregistered multilevel regression analysis using data from 6,237 ninth‐grade adolescents in 25 U.S. high schools showed a three‐way interaction: Implicit theories moderated the associations between victimization and depressive symptoms only in schools with high levels of school‐level victimization, but not in schools with low victimization levels. In high‐victimization schools, adolescents who believed that people cannot change (an entity theory of personality) were more depressed when they were victimized more frequently. Thus, the mental health correlates of adolescents’ implicit theories depend on both personal experiences and the norms in the context. 相似文献

Due to a range of shortcomings of income-based measures of poverty in older people, an alternative approach is proposed to counteract those shortcomings. Hong Kong index of material deprivation aims to identify a consensus-based list of goods and services that are necessities in society and to establish that these goods and services are not available due to their lack of affordability. This paper reports on the validation of Hong Kong index of material deprivation based on an approach proposed by Townsend (Poverty in the United Kingdom, Penguin Books, London, 1979) in Hong Kong. Through a survey of 2339 older Chinese people aged 65 and older, we found that a broad consensus regarding the necessities in their daily lives exists and Hong Kong index of material deprivation is a reliable and valid measure of poverty because its reliability and validity is good and acceptable. Finally, we have shown that the overlap between the poor in terms of income and the deprived is moderate and the profiles of those who are core poor (both poor in terms of income and the deprived) are more similar to those who are deprived than those who are poor in terms of income. Hong Kong index of material deprivation index has been developed, which offers a supplementary measure of poverty other than income poor and provides future avenues for improved understandings of poverty in old age. 相似文献

We implement a field experiment with hotel guests to measure the effects of nonprice interventions on water conservation and customer satisfaction. In hotels, guests have no direct pecuniary incentive to conserve water, as consumers do at home, where they pay their own water bills. Because hotels earn greater profits when they manage to convince guests to conserve, guests may be suspicious of a hotel's stated social goal of water conservation. By implementing behavioral interventions that address these challenges, we find that our nudges can induce guests to reduce their water consumption, even when no direct monetary incentive is provided. Using post‐stay customer surveys, we detected no adverse effects on customer satisfaction due to these nudges. (JEL D12, I31, Q41, Q50) 相似文献

The purpose of this exploratory study was to expand upon previous literatures in public relations power, and fill the need for more scholarship regarding practitioners’ perceptions of social media work, power, and gender. Findings from a survey of PRSA members showed that there is a gendered difference in power perception between males and females regardless of their PR roles or level of experience, but social media expertise was perceived equally between both genders. We argue that while social media expertise may serve to reduce a gendered power divide in public relations, continued critical exploration of social media and gender inequality is necessary. 相似文献
