姜志德 《西北农林科技大学学报(社会科学版)》2001,1(4):57-61
在深入研究土地利用与可持续发展关系的基础上 ,提出土地资源可持续利用概念的新定义 ,进而以土地利用生态经济系统为分析框架 ,对土地利用可持续性内涵的作出合理解释。土地资源可持续利用是能够不断满足人类可持续发展需要的土地利用 ,其内在本质是要建立和保持一个运行良好的土地利用系统 ,土地利用的可持续性指的是系统运行在不断增加人类产出效益的同时不妨碍该系统再运行能力的连续保持和提高 相似文献

预期寿命增长、年龄结构改变与我国国民储蓄率 总被引:1,自引:0,他引:1
人口年龄结构趋于老龄化和人均预期寿命逐步增长是目前我国人口发展的两个典型特征,而年龄阶段不同,个人的收入、消费与储蓄行为也不同。基于生命周期理论,在选定相关分析指标的基础上,文章使用我国省际平衡面板数据,实证分析了我国人口预期寿命增长和年龄结构改变对国民储蓄率的影响。分析结论表明,人口预期寿命增长提高了我国国民储蓄率;不考虑时间效应时,幼年人口负担比提高会减少国民储蓄率,而老年人口负担比提高会增加国民储蓄率;在考虑时间效应时,幼年人口负担比提高会增加国民储蓄率,而老年人口负担比提高会减少国民储蓄率。对此,文章给出了合理的解释。通过使用多种估计方法,我们发现所得到的结论是基本稳健的。 相似文献

Based on a sample of British dual earner families with young children drawn from the National Diet and Nutrition Survey, the paper examines their food practices, in particular the conditions under which families are able to eat together or not during the working week. The concept of synchronicity is drawn upon to shed light on whether meals and meal times are coordinated in family life and the facilitators and constraints upon coordination. The paper suggests that whether families eat together is not only influenced by parents' work time schedules but also children's timetables relating to their age and bodily tempos, their childcare regimes, their extra-curricular activities and the problem of coordinating different food preferences and tastes. 相似文献

Employees' expected contributions can be incongruent with those of their leader. We examine the congruence effect of leaders' and employees' expected contributions on job satisfaction. Results of cross-level polynomial regressions on 947 employees and 224 leaders support the congruence effect. When expected contributions are congruent, employees are more satisfied with their job. Our findings suggest that employees enjoy high challenges, as long as these challenges are in harmony with the expected contributions of their leaders. Employees are less satisfied with their jobs both when their expected contributions were higher than their leaders' and when their expected contributions were lower than those of their leaders. Beyond the relevance of having high expected contributions, the findings highlight the crucial role played by the congruence of expected contributions of leaders and employees. 相似文献

Dealing with Migrants in the Central Mediterranean Route: A Legal Analysis of Recent Bilateral Agreements Between Italy and Libya 下载免费PDF全文
Andrea de Guttry Francesca Capone Emanuele Sommario 《International migration (Geneva, Switzerland)》2018,56(3):44-60
Dealing with the current flow of migrants flocking to the shores of southern European countries remains high on the international agenda. At the end of 2016, 276,957 migrants were waiting in Libya to cross the sea. Many of them were subject to human rights violations and abuses such as arbitrary detention, torture, unlawful killings, sexual exploitation and even slavery (IOM, 2017). The international response has been, so far, insufficient and new ideas and practices are urgently needed. After providing an overview of the legal framework and of the efforts carried out by the relevant international and regional organizations, this article focuses on recent treaties concluded between Italy and Libya, and argues that the new bilateral agreements represent an example of how States are responding to this challenge in an attempt to strike a balance between the need to strengthen the protection of migrants’ rights and the necessity to guarantee the security of national borders. 相似文献

‘What Was I Thinking?!’ Rhetorical Questions as a Technique to Identify and Explore Impasses in Therapy 下载免费PDF全文
Rhetorical questions emerging spontaneously in consultations can be used as a tool for developing self‐reflexivity and exploring the therapeutic alliance in the process of therapy with couples and families. This paper presents a technique based on the enunciation of rhetorical questions, which can point to an impasse in the process of therapy and contain a key to its resolution. The technique focuses on the distinctive feature of rhetorical questions as convening a paradoxical injunction: a question not intended as a question, while uttered as such. The technique in four steps is illustrated by examples from therapy, supervision, consultation, and self‐supervision. Its focus is the interlink between the therapeutic relationship and the process of therapy and it is informed by a second‐order cybernetics approach, dialogical practice, and the systemic literature on emotion. The technique can help develop curiosity in working with families, lead to unforeseen developments, and touch on prejudices not made explicit in previous therapeutic encounters. Whether we are acting as supervisors, therapists, or clients, the creation of a ‘secure enough’ context for rhetorical questions becomes critical to allow freeform exploration. 相似文献
