地勘单位产权制度改革“引”与“退”的几点思考

地勘单位产权制度改革进展缓慢,存在着思想认识、理论指导和实践操作的问题。这些问题都应在改革中逐步解决。地勘单位在产权制度改革上要敢于大胆地引进和大胆地退让,以实现股权多元化。要处理好“引”与“退”的辩证关系,有计划地引进、有计划地退让。根据不同项目、不同领域的具体情况确定参股或控股,以使地勘单位走上所有制多元化之路。     

七通道抗干扰GNSS接收机射频前端设计

针对目前全球卫星导航系统(Global Navigation Satellite System,GNSS)普遍存在的抗干扰能力弱的突出问题,研制了一款七通道抗干扰GNSS接收机,通过利用多模组合导航抗干扰技术及级联/组合空域、时域与频域等多重抗干扰技术来应对复杂电磁环境应用的需求。重点介绍了抗干扰GNSS接收机射频前端的设计方法,通过数理推导给出了产品设计需求与整个射频前端及各级电路的设计指标之间的定量关系,从而提供了在已知设计需求的条件下进行产品正向设计的设计准则与方法。通过产品投产和测试,测试结果与设计需求吻合,从而验证了该套设计方法有效可行,同时该套准则与方法具有很强的普适性。与同类产品比较以及整机试验表明,该产品的抗干扰能力(主要体现为最大可承受干信比)较同类产品提升20 dB以上,证明产品具有一定的先进性。

“诗言志”与“诗缘情”矛盾的非矛盾性

一直以来,理论界将＂诗言志＂与＂诗缘情＂对立起来,从而形成文论发展的两个不同流派,似乎两者之间存在着某种不可互渗互补的矛盾性。事实上,理论界长期流行的这种＂矛盾＂说法有失偏颇。在中国文论发展史上,这两种说法不仅在文本来源上造就了一种虚假的矛盾性,而且在以＂情＂为本体的观念上也分化了两者的交叠重合,而＂诗言志＂与＂诗缘情＂矛盾的真正根源在于儒道观念的差异。

我国实施“走出去”战略的必要性和政策措施——基于投资发展路径理论对我国的实证研究

“走出去”战略是我国改革开放实施的重大战略性决策。本文从战略研究角度,对我国发展“走出去”的必要性进行了分析和探讨;并根据投资发展路径(IDP)理论对我国的对外净投资和人均国民收入关系作了实证检验,证明了我国处于投资发展周期的第二阶段,应大力发展对外直接投资,积极实施“走出去”战略;并对我国企业对外直接投资的政策措施提出了建议。     

我国财政支出规模变化的分析及其合理控制

文章对我国改革开放以来财政支出规模的变化趋势进行了实证分析,揭示了我国财政支出规模下降的背后仍然是政府实际支配资源规模的扩大,对这种变化趋势的合理性进行了分析判断,剖析了我国“财政之谜”(财政支出规模下降而企业负担重)的实质,给出了我国适度财政支出规模的基本要求及界定标准,提出合理控制我国财政支出规模的基本思路就是根据公共财政的内在要求,系统改造现行财政支出制度安排,构建符合公共财政要求的公共财政支出制度框架。     

Are social media bad for your employees? Effects of at-work break activities on recovery experiences

Since social media has become a fundamental part of the daily activities of people, the purpose of this study was to explore social media use by focusing on job demands that may explain why employees perceive social media are vital for them at work. Further, this study seeks to understand how employees use social media at work to experience recovery. Questionnaires were collected from current frontline hospitality non-managerial and managerial employees in the United States. Structural equation modeling was employed to analyze data. Results of the study confirm that at-work break activities including social and non-media break activities can be a channel for employees to experience recovery and deal with job demands. Moreover, the results suggest that at-work break activities are an important mediator between job demands and recovery experiences. Social media break activities also moderated the mediation effect of non-social media break activities between job demands and recovery experiences.     

A social identity perspective of social media's impact on satisfaction with life

Social media platforms have become an (almost) obligatory part of our lives and activities. However, many disadvantages have emerged such as an increase in dependency on social media owing to addictions known as the dark side of social media. The current research seeks to understand the impact of specific aspects of this dark side, viz. social media addiction, fear of missing out, and narcissism, on self-esteem, and their links with an individual's satisfaction with life (SwL). The results of a quantitative survey (n = 260) show the salient impact of these aspects on self-esteem as well as the preponderant role of collective self-esteem in SwL. Academic and managerial implications are discussed.
