从天文之美到暗夜保护——科学、艺术、环保融合理念下的天文科普实践

科学普及是实现国家创新发展的两翼之一，是提升全民科学文化素质的重要工作。针对新时代中，公众对科普服务的多元化需要，分析论述作为自然科学之一的天文学具有天然的艺术美属性，具备很强的科学与艺术相结合开展科普工作的基础。同时，从天文观测与暗夜的密切关系出发，论述了在“我们应该追求人与自然和谐”的科学环保观的理念下，将暗夜星空保护融入天文科普中的必要性，分享了北京天文馆将天文之美、暗夜保护等内容融入天文知识传播中的科普实践工作案例，得出了开展科学、艺术、环保融合理念下的天文科普工作符合公众和时代需求的结论。     

A new innovation paradigm: European cohesion policy and the retreat of public science in countries in Europe's scientific periphery

This article seeks to undertake a critical assessment of the changing position of public science in the entrepreneurial ecosystem of the countries on the periphery of European research. These countries are driven by new innovation paradigm based on entrepreneurship, which are implemented within the European Smart specialization strategy (S3). This article argues that S3 is widely implemented in the cohesion countries and, while it provides substantial resources for science, technology, and innovation, it fails to provide sustainability in the public research sector. This has direct implications for policies concerning innovation and entrepreneurial ecosystems. In order to prove the thesis, the article provides theoretical argumentation for emergence of a new innovation paradigm, driven by the rise of the entrepreneurial ecosystem, its incorporation into S3, and a consequent retreat of science policy in favor of entrepreneurial policy. The empirical analysis is focused on the funding trends seen in the business and public research sectors over the last decade (2008–2017), which have clearly shown that S3 has not contributed, despite expectations, to an increase in public expenditure for science. This signifies S3's neglect of public research within entrepreneurial ecosystems and challenges the ability of S3 to reduce wide disparities in research and innovation performance across the European Union. This ultimately endangers the innovation potential of the entrepreneurial ecosystem itself.     

亲子亲合对农村留守儿童孤独感的影响研究

根据亲子沟通频率(高-低)、亲子亲密度(强-弱)将亲子亲合分为积极型亲子亲合、消极型亲子亲合、默契型亲子亲合、放任型亲子亲合四种类型。通过采用西安交通大学课题组与西南财经大学课题组2017年在四川省金堂县联合开展的留守儿童调查数据,探讨亲子亲合对农村留守儿童孤独感的影响。调查发现,四川省金堂县农村留守儿童存在较高的孤独感问题,基于logit模型进行实证分析发现,不同亲子亲合类型对农村留守儿童孤独感的影响存在差异,积极型亲子亲合有利于缓解农村留守儿童孤独感,默契型亲子亲合对农村留守儿童孤独感的缓解作用不显著,放任型亲子亲合加剧农村留守儿童孤独感。提出鼓励多元主体参与构建农村留守儿童关爱服务体系,促进农村留守儿童的健康成长。     

云南省农业科技创新资源配置效率及影响因素研究

[目的]为及时了解云南省农业科技创新的最新动态,充分合理地开发云南省农业科技资源,文章对2002—2016年云南省的农业科技创新资源配置进行研究。[方法]首先分析各个单项指标15年内的变化趋势,分析其对资源配置的影响和作用。再运用DEA模型分析法,将2002—2016年的每个年份作为一个决策单元进行处理,对云南省农业科技创新资源配置效率进行分析。[结果] 2002—2016年云南省农业科技创新资源配置的综合效率为0. 984,并且呈现出不稳定的波动,在2004和2009—2012年出现了配置效率降低的情况。总体来看,资源配置的综合效率大体上是接近于1的水平。处于DEA有效的年份为2002—2003年,2005—2008及2013—2016,属于规模报酬不变的阶段; 2004年属于弱DEA有效阶段,规模报酬则处于上升阶段;处于非DEA有效的有2004年、2009—2012年。[结论]云南省农业科技创新资源的配置效率整体水平处于较高的状态,综合效率值总体上接近于1。有个别年份出现了较小范围的波动,可能与总播种面积的变化有关。综合来看,云南省农业科技创新资源在技术投入、人力资源和农业资金投入逐年的增加,使资源配置效率能够保持在较高的水平,并在出现下降后迅速恢复。     

Here comes Generation Z: Millennials as managers

As the workplace continues to change, a new generational cohort—Generation Z, sometimes referred to as iGen—is beginning to enter the workforce. At the same time, millennials are now progressing in their careers and will be challenged with managing these incoming workers. The purpose of this article is to provide a contextual overview that identifies and illuminates some of the defining work-related characteristics of these two youngest generations in the workplace to increase understanding of the potential intergenerational conflict between these cohorts and develop leadership strategies that can be utilized to increase employee morale and productivity. This article analyzes the millennial supervisor-Gen Z subordinate relationship based on generational cohort theory, leader-member exchange (LMX) theory, and the work values framework.

Non-stationary additive utility and time consistency

Within a continuous time life cycle model of consumption and savings, I study the properties of the most general class of additive intertemporal utility functionals. They are not necessarily stationary, and do not necessarily multiplicatively separate a discount factor from “per-period utility”. I prove rigorously that time consistency holds if and only if the per-period felicity function is multiplicatively separable in $t$, the date of decision and in $s$, the date of consumption, or equivalently, if the Fisherian instantaneous subjective discount rate does not depend on $t$. The model allows to explain “anomalies in intertemporal choice” even when the agents are time consistent and various empirical regularities. On the other hand, the model allows to characterize mathematically the “effective consumption profile” of naive, time-inconsistent agents.     

Cultural distance and international trade in services: A disaggregate view

In this paper, we estimate the effect of “cultural distance” on bilateral trade in services. The measure of cultural distance we use is based on scores that reflect country averages of individuals’ attitudes towards inequality, self-orientation, competition, uncertainty, traditions, and indulgence. Controlling for standard ingredients of gravity equations, we show that an aggregate measure of cultural distance has a significantly negative effect on total bilateral services trade. Once we take a more disaggregate view, we find that the strength of this effect differs across various types of services and various aspects of cultural distance.     

Financial analyst coverage for U.S. firms facing foreign competition: Evidence from trade liberalization

This study examines financial analyst coverage for U.S. firms following an increase in foreign product market competition. To capture exogenous shocks to domestic firms' competitive environments, we exploit a quasi‐natural experiment from large import tariff reductions over the 1984 to 2005 period in the manufacturing sector. Using data for the years before and after large tariff reductions, our difference‐in‐differences analysis shows evidence of a significant decrease in analyst coverage for incumbent U.S. firms when they face greater entry threat from foreign competitors. We also find that analysts with less firm‐specific experience and less accurate prior‐period forecasts are more likely to stop following the domestic firm when foreign competition intensifies. Overall, the findings suggest that foreign product market competition from global trade liberalization is an important determinant of financial analysts' coverage decisions.
