从CSSCI引文年代分布看中国社会科学期刊影响因子的计算

Garfield等在20世纪60年代提出的期刊影响因子是评价期刊的重要指标之一。对中文社会科学引文索引(CSSCI)来源论文之引文年代分布及其与美国社会科学引文索引(SSCI)的比较分析说明两者基本一致,对CSSCI引文中中文期刊、中文社科学术期刊及CSSCI来源期刊的年代分布分析说明:中文社科期刊的被引高峰期与国际期刊被引高峰期相同,均在其出版后的第二年和第三年。国际通用的影响因子算法完全适用于中国的中文人文社会科学期刊。     

生态系统服务消耗及其影响

对生态系统服务直接与间接消耗的模式、机制与影响研究,以及如何把人类对生态系统服务消耗与自然生态系统本身结合起来,是富有挑战性和前瞻性的研究工作。但是,生态系统服务消耗仍然是一个及其需要强化的研究领域。本文结合村落及区域尺度研究进展,分析了生态系统服务直接与间接消耗的特点,阐述了消耗及其格局变化对生态系统本身的影响,以及对土地资源质量和数量、对水资源数量和产能影响的特点。同时,论述了实现从农户到区域尺度个体生态服务消耗模式变化及区域演变规律的跨尺度定量模拟与表达,为实现可持续消耗模式及生态系统适应性管理提供参考。

A possible teleology of cultural sector data in England

ABSTRACT

In March 2019, Arts Council England (ACE), an official statistics producer, started collecting a new set of data from its National Portfolio Organisations intended to reveal whether those organizations’ intentions correlate with the perceptions of their peers and audiences. In a world dominated by quantitative data, the Impact and Insight Toolkit addresses a perceived lacuna and marks a substantial investment in qualitative metrics. ACE also expects it to address a number of other concerns – help organizations self-evaluate, measure their short-term outcomes and advocate more effectively. Indeed, it envisages that an aggregation of the data collected will support the case for sustained public support of the sector. The Toolkit’s launch comes at a time when changes to the UK’s official statistics are encouraged, and policymakers are looking elsewhere to inform their thinking. The campaigning aspect of ACE’s aspirations suggests a model of data collection and analysis distinct from that of official statistics production, valued for its impartiality. This article considers what might happen if the Toolkit, which relates to ACE’s role as a development agency, encourages data to be collected and analysed in order to deliver specific outcomes. It reflects on three visions of cultural sector data from the past 50 years: Toffler’s The Art of Measuring the Arts, DCMS’s Taking Part and ACE’s Impact and Insight Toolkit. These suggest a trajectory of cultural sector data determined by increasing importance being attached to institutional interests, and implies that the future of cultural sector data in England may be determined by how ACE addresses its potentially conflicting interests as an official data provider and development agency. Greater investment in the former would more accurately reveal the arts’ contribution to economic and social development; greater investment in the latter would encourage the teleological development of cultural sector data designed for sectorial advocacy.     

不同学科分类体系对机构科研影响力评价的影响研究

[目的/意义] 探讨不同学科分类体系在机构科研影响力评价中的差异及对评价结果的影响。[方法/过程] 以Incites数据库为数据来源,选择5种分类体系、8种分类方案。首先对14 955个机构不同分类方案下的学科标准化引文影响力(Category Normalized Citation Impact,CNCI)进行相关性分析,考察不同分类体系下评价结果的整体相似性。然后以国内双一流建设中的36所高校为例,比较和分析不同分类方案下机构CNCI值的变化情况及差异产生的具体原因,研究分类体系对个体机构评价的影响。[结果/结论] 不同学科分类方案下得到的CNCI值相关性显著(最低相关性达到0.85),即不同分类体系得到的整体评价结果具有较高的相似度。但是不同分类体系下的评价结果也存在聚类特征,OECD、ESI、SCADC、CT1相互之间相关系数高、结果更相近,WoS、CT2和CT3评价结果更接近,分类体系的粒度是决定评价结果的重要因素。36所高校在不同的分类体系下评价结果的整体相关性较高,但个别高校CNCI值变化较大,特别是在热点主题上有突出发文的机构。评价结果的巨大差异其根本原因是论文划分到不同类目中,不同类目下的引用基准值不同。在评价过程中更加推荐粒度较细的分类体系,减少热点主题等对引用基准值的影响。

我国当代暴力文化对暴力犯罪的影响探析

暴力文化是记载、描述暴力行为人实施暴力行为的具体过程及主观故意心理状态的一种亚文化,具有载体的多样性、内容的丰富性、表现行为的凶残性等特征。而暴力犯罪是行为人以暴力或以暴力相威胁的手段侵害他人人身、财产权的应受刑罚处罚的行为,具有突发性、残酷性、冒险性等特征。暴力文化与暴力犯罪关系相当密切。暴力文化在一定程度上滋生了暴力犯罪,严重影响了社会主义经济建设。暴力文化和暴力犯罪必须从刑事立法、行政立法上予以区分遏制,才能保障社会主义市场经济正常运行,构建和谐、法制的社会主义国家。     

"If I Want It, It's OK": Usenet and the (Outer) Limits of Free Speech

Usenet is an international communications system composed of thousands of topically named discussion groups, called newsgroups, which enable anyone with an Internet connection and the proper software to read messages, post new messages, or reply to existing ones. Remarkable for its culture of 'anything-goes' free speech, Usenet tradition recognizes only one kind of legitimate restriction on content: that which is abusive to the Net's ability to function as an effective discussion system. This article shows that this consensus stems from a long and often painful struggle, as Usenet's designers, administrators, and users attempted to comprehend, define, and govern the communication system they had created. The result is a forum that is not quite as free as Usenet's defenders like to imagine, and one given to excesses that seem destined to attract the attention of government censors.

组织学习、知识管理与组织创新的耦合性研究

首先分析组织学习、知识管理与组织创新三者两两之间的关系,发现组织学习过程与知识管理过程是相互伴生的,组织知识存量突破一定的阈值会使得组织创新的方式发生改变,在组织创新的不同阶段伴随着不同形式的组织学习。接着,详细论述组织学习、知识管理与组织创新通过知识的获取、转移、共享和运用联系起来,在改变企业知识状态的过程中,彼此之间相互联系、相互作用,存在着耦合性关系。
