This study investigated the influence of some personal and job resources and of some job demands on the three dimensions (absorption, work enjoyment, intrinsic work motivation) of flow at work, on the basis of Job Demands-Resources Model. Flow at work is an inner experience arising during an activity in which people are immersed, feel motivated and enjoy it. Studies suggest that resources are the main antecedents of the flow experience. Respondents to the questionnaire were 197 nurses. Multiple regressions were performed to detect the resources and the demands that influence the three dimensions of flow at work. As expected, resources positively influenced the dimensions of flow at work, particularly work enjoyment. Job demands positively influenced absorption and negatively influenced the other two dimensions of flow at work. Human resources managers should promote flow at work supporting the availability of resources and monitoring the job demands.展开更多
大规模需求市场是构建“双循环”新发展格局的核心优势之一,也是重塑全球价值链的重要力量。拓展Antràs and Gortari的全球价值链地理模型,理论分析大规模需求市场对全球价值链生产空间分布的影响,并借助WIOD数据,构建大规模需求...大规模需求市场是构建“双循环”新发展格局的核心优势之一,也是重塑全球价值链的重要力量。拓展Antràs and Gortari的全球价值链地理模型,理论分析大规模需求市场对全球价值链生产空间分布的影响,并借助WIOD数据,构建大规模需求市场临近距离指标进行实证检验。研究发现,大规模需求市场诱致全球价值链生产空间集聚,具体表现在:第一,越临近大规模需求市场,地区的全球价值链生产位置越呈现下游化,且下游生产环节间空间临近性越强;第二,越临近大规模需求市场,参与全球价值链的后向地理优势越强,后向参与度越高;第三,越临近大规模需求市场,价值链长度越向外延伸,区域内部生产联系越强。并且,以上生产空间集聚存在行业差异,主要表现在规模经济较强及运输成本较高的行业。研究结论为全球价值链区域化发展与价值链区域化存在的风险提供理论证据,为“双循环”新发展格局下协调扩大内需战略与主导区域价值链建设之间关系的政策设计提供参考。展开更多

文摘干旱半干旱地区水资源缺乏,准确地计算区域生态环境用水和生态环境需水,可以对稀缺水资源进行合理调配,同时起到生态保护的作用。研究过程主要分为两个步骤:(1)采用RS技术,对新疆哈密地区1990年、2000年、2005年中巴资源一号卫星(China Brazil Earth Resources Sat-ellite)数据进行解译,形成1990年、2000年、2005年哈密地区土地覆被图形数据和相应的属性数据,确定相应年份各景观类型的面积;(2)参考有关研究并结合哈密地区实际情况,确定各景观类型的单位生态用水定额和需水定额,进而计算出1990年、2000年、2005年哈密地区的生态用水量,并以2005年哈密地区生态用水量为主要依据计算出保持哈密地区生态环境现状的生态需水量。研究结果表明,为了实现哈密地区生态环境整体保持在现状水平不致恶化、局部区域生态环境(巴里坤湖区)有所改善的生态治理目标,区域内生态环境需水总量为7.526×109m3,这一庞大的需水量将对该地区水资源配置造成巨大的压力;而当结合各类景观的地物空间位置特征进行分析时,发现该区域生态用(需)水量最大的景观(低覆盖草地)可以利用山地积雪融水进行自给,区域内实际需要规划配置的生态环境需水量为2.66×108m3,仅占区域生态环境需水总量的3.53%。在区域生态用(需)水计算过程中应考虑各种景观类型的生态用(需)水量的时空差异性,以保证水资源调配的科学与合理。
