论袁世凯小站练兵背后的保荐者

西法练兵,是甲午战后晚清朝廷上下的一致呼声,袁世凯顺应历史潮流成为改练新军的倡议者和支持者,凭借自己的才能、经历、政治关系,以及不懈的奔走和钻营,终于取得了督练新军的大权。然促成这一事者,当数刘坤一、李鸿藻、荣禄三人出力最多,之所以举荐袁世凯是基于其各自不同的政治立场和目的,但这一事实无疑是顺应当时的发展趋势的,具有一...     

Benefits and challenges of voluntary contribution to GEOSS

The vision of the Global Earth Observation System of Systems (GEOSS) is the achievement of societal benefits through voluntary contribution and sharing of data, metadata and products at no or minimum cost. Such undertakings, where contribution provides positive externalities, benefiting contributors and non-contributors alike, are often described as ‘social dilemmas’, usually resulting in small levels of voluntary contribution. We investigate the benefits and challenges of voluntary contribution to GEOSS, surveying economic and game theoretic literature and examining how the concepts of social dilemmas apply to the provision of GEOSS. We conduct an exploratory survey among individuals involved in the Group on Earth Observation (GEO) to understand their perception of voluntarily contribution. Even though contribution to GEOSS was perceived as rather low, e.g. because of a perceived lack of funds, commitment or organization, survey respondents also perceived many (exclusive) benefits of contribution, e.g. networking, visibility for their work or collaborating with motivated individuals. To increase participation, respondents suggested increasing financial support and raising awareness of GEOSS. We conclude that communicating the efficacy of individuals' contributions, the personal benefits of contribution and strengthening of group identity and knowledge about fellow participants' work can constitute incentives for future voluntary contribution. This could be facilitated by an externally established institution providing a framework for cooperation, or by institutions, agreements or frameworks agreed upon by contributors themselves.     

Amateur observations of solar eclipses and derivation of scientific data

This work presents the educational approach of using total solar eclipse occurrences as a scientific process learning aid. The work reviews the basic scientific aims and experiments included in the observational programs “Total solar eclipse 1999 and 2006” (Stoev, A., Kiskinova, N., Muglova, P. et al. Complex observational programme of the Yuri Gagarin Public Astronomical Observatory and STIL, BAS, Stara Zagora Department for the August 11, 1999 total solar eclipse, in: Total Solar Eclipse 1999 – Observational Programmes and Coordination, Proceedings, Recol, Haskovo, pp. 133–137, 1999a (in Bulgarian); Stoeva, P.V., Stoev, A.D., Kostadinov, I.N. et al.

论新型城镇化背景下的人的现代化

城镇化是现代化的必由之路,尽管在发展的硬指标上新型城镇化的任务还比较艰巨,但也不能因此而忽视城镇化的软指标,即人的现代化.人的现代化的核心在于文化观念的转换,传统文化的观念系统存在着诸多影响现代化发展的因素.开展持久的关于现代文化意识的启蒙教育,在政治、经济制度领域实现彻底的现代转型,是实现人的现代化的关键.
