工作和家庭关系研究的新思路——工作-家庭丰富研究综述

近年来对工作家庭相互之间关系的研究不仅仅关注工作家庭间的冲突,而且越来越重视工作和家庭的相互积极作用,从更加辩证的角度考察工作和家庭之间的相互作用。本文对工作家庭丰富的研究进行了回顾与总结,并对未来的研究提出建议。     

试析不当得利返还请求权与其他请求权的关系

不当得利请求权和民法上的其他请求权之间的关系问题，即是一个理论问题，也是一个实务问题，不仅涉及民法各项制度的功能体系，也事关不当得利返还请求权在处理民事案件中作用的发挥。以财产上的请求权发生的基础为核心，不当得利与合同、无因管理、物的返还、侵权行为等之间的关系的适用性，仍是实践中存在的突出问题。我们应承认不当得利返还请求权的独立性，并在此基础上承认它与其他财产上请求权可能发生的竞合，这样有助于民法各项制度的功能协调，有利于更加充分地实现民法维护公平正义这一根本理念。     

利益偿还请求权价值和性质探析

票据利益返还请求权作为票据法上一项特殊权利,在其性质方面争议颇多,我国学者普遍认为其是一种特别请求权。笔者认为特别请求权说并不能反映利益偿还请求权的本质,反而把该权利的性质变得更加深不可测。本文探讨了票据利益返还请求权的价值、性质,认为票据利益偿还请求权是一种不当得利请求权。     

毛泽东对马克思中间阶级理论的丰富与发展

毛泽东从中国革命及社会主义现代化建设的实际出发，对马克思的中间阶级理论进行了科学的理论诠释和实践诠释，形成了中国化的马克思主义中间阶级理论，对中国当前的小康社会建设和中国特色社会主义事业具有具有重大的理论指导意义。     

Reactions to unjust dismissal and third-party dispute resolution: A justice framework

Little previous research has examined why dismissed workers view their discharge as unjust and how they respond to third-party dispute resolution interventions. This exploratory field study relied upon a justice framework to understand complainant motivations for filing unjust dismissal disputes and their reactions to a voluntary conciliation program. Analysis of archival and interview data suggested that procedural justice principles dominated both motivations for filing claims and reactions to third-party intervention. These findings were consistent with previous justice and labor relations research. Implications for future research, management practice, and third-party dispute resolution are discussed.     

Can taking charge at work help hospitality frontline employees enrich their family life?

Managing work-family interface has been a key issue for hospitality employees. By integrating the literature on thriving at work into the work-family enrichment model, this study proposes taking charge as a resource-generating behavior that employees could undertake to enrich their family life. Using data collected on two occasions from frontline employees and their supervisors in a hotel in China, we find that those who take charge are more likely to experience thriving at work, which helps them improve the quality of their family life. Furthermore, working under a leader facing high role ambiguity augments this relationship. The study findings advance current work-family enrichment literature, and also carry important practical implications for promoting employees’ work-to-family enrichment in the hospitality sector.     

北京园林绿地6种树木的叶片和一年生枝中5种重金属含量比较

为了解不同园林树木对重金属的吸收情况，以北京市陶然亭公园、紫竹院公园、中科院植物园、马甸公园、皇城根遗址公园和营城建都滨水绿道不同环境绿地为样地，选择样地间共有的园林树木，采用ICP光谱仪测定了6种树木叶片和一年生枝条中重金属锌(Zn)、铬(Cr)、镍(Ni)、砷(As)和汞(Hg)的含量，以此为基础，采用隶属函数法将6种树木单位重量对5种重金属的综合富集能力进行排序，并对同树种叶片与当年生枝、5种重金属吸收量分别进行相关分析。结果表明：1)不同树种叶片和一年生生枝条单位重量中重金属含量有显著差异，且因重金属种类而异。Zn、As含量最高的为金银木，Cr、Ni、Hg含量最高的依次为圆柏、侧柏、丁香；丁香富集Zn、Cr、As的能力最低，白皮松富集Ni能力最低，侧柏富集Hg能力最低。2)树木叶片和当年生枝单位重量对5种重金属综合富集能力排序为：金银木＞侧柏＞圆柏＞油松＞丁香＞白皮松。其中，针叶树种中圆柏、侧柏、油松富集5种重金属的综合能力显著高于白皮松(P＜0.01)，阔叶树种中金银木吸收重金属的能力显著高于丁香(P＜0.01)。3)树木不同器官中重金属含量也不同，不同树种间叶片与枝条中仅Cr含量具有显著相关性，相关系数为0.461(P＜0.01)，其他4种元素均未达到显著水平。4)同树种叶片和当年生枝Cr和Ni吸收呈极显著相关性(P＜0.01)，其他元素吸收之间未呈现相关性。本研究结果对北     

砂岩型铜矿成矿机制分析

近年来,我国各地发现大量的砂岩型铜矿,一时间出现了寻找砂岩型铜矿的热潮。本文通过分析云南省宁蒗县砂岩铜矿的地层、构造、岩浆活动、沉积环境、化学组成,探求其矿床成因,认为区内三叠系砂岩和砂页岩在还原环境下有利于铜矿富集,喜马期的岩浆及热液活动是矿进一步富集的重要因素。     

Disentangling organizational commitment in hospitality industry: The roles of empowerment,enrichment, satisfaction and gender

This Paper identifies how the motivational strategies of empowerment and enrichment affect on the organizational commitment of hotel staff, and how the job satisfaction mediates in these relationships. We applied a Structural Equations Modeling to a sample of 257 front line hotel employees from Madrid, of which 144 were men and 113 were women. Our results provide evidence about several contributions: first, employees empowerment significantly grows job enrichment and organizational commitment; second, job enrichment increase workers’ satisfaction and commitment; third, job satisfaction enhances organizational commitment; fourth, job enrichment plays a mediating role between empowerment and both satisfaction and organizational commitment; fifth, satisfaction mediates between enrichment and commitment; finally, gender moderates the relationship between enrichment and commitment.     

工业化背景下资源富集地区农村产业结构调整和模式研究

农村产业结构与当地的经济发展之间存在着必然的关联,一般来说合理的产业结构能够使各种资源得到合理的配置,从而促使当地经济取得良好经济发展效益.本文选择典型资源富集区的榆林作为研究对象,通过分析近10年来产业结构调整背景下资源富集区能源开发与农村经济发展的问题,提出该区域农村产业结构调整的模式和相应政策、建议,为研究能源富集区农村产业结构调整提供了一种新思路,也为其他能源富集区农村产业结构调整提供借鉴.
