论文发表系统:完备分类与中长期格局演化

[目的/意义]互联网时代出现看多种新论文发表系统,对多种论文发表系统之间逻辑分类关系以及彼此之间的中长期格局演化进行讨论。[方法/过程]从论文发表系统对一篇论文是否进行评议、评议是否分级、是否拒稿3个维度提出论文交流系统分类框架,将期刊、预印本、F1000 Research、在线评级平台4种论文发表系统全部统一在一个分类框架中。另外,基于研究者与研究管理部门对论文交流系统的不同需求,定性分析了论文交流系统的中长期演化格局。[结果/结论]中长期看,在线评级平台将对期刊系统形成明显冲击,期刊内部两极分化。     

Fiḍḍa l-Nūbiyya: The Woman and her Role in Early Shīՙite History

The purpose of the present study is to analyse the role played by an important female figure in early Shī?ite history. The person in question is Fi[ddot][ddot]a l-Nūbiyya, the servant-girl of Fā ?ima, the Prophet's daughter. After a long period of neglect by scholars, who have focused on what to their mind were figures of greater import, we shall here attempt to describe the role played by Fi[ddot][ddot]a in early Shī?ite history by way of analysing her biography and her close relations with Fā ?ima and members of the latter's family (?Alī, [Hdot]asan and [Hdot]usayn). We shall further describe what has been reported of Fi[ddot][ddot]a's personality, her family, her admiration for the Prophet's family, Qur?ānic verses which supposedly mention her, and the great respect in which she was held by Fā ?ima's family.

架设三二连续“中高职贯通”立交桥——关于“三二连读”人才培养工作的几点思考

实施中高职＂三二连读＂体制改革模式的目的是培养社会需要的合格人才。要明确合作定位：以构建职教集团来实践、探索一种新的中高职衔接的模式;要明确目标定位：力求特色发展、品牌打造,合作共赢。高职教育面临着＂学教做合一＂教育观的确立、高职教育课程改革推进、教学管理与学生服务一体化的实施等一系列亟待解决的问题,而以＂三二连读＂为载体的中高职衔接新模式将可以为高职教育发展拓展新的空间,而坚持高职教育高素质高技能的应用型人才培养定位,可以为社会培育合格的＂全人＂。这些都是高职教育的生命力所在。     

Kinship,Camaraderie and Contestation: Fāṭimid Relations with the Ashrāf in the Fourth/Tenth Century.

The founding of the Fā?imid caliphate across the southern Mediterranean, and then in Egypt, Syria and the ?ijāz at the turn of the fourth/tenth century, necessitated its negotiation with the ashrāf, those who claimed lineal descent from the Prophet Mu?ammad, and who by this time had gained significant influence as a social class based on their charismatic descent. While other dynastic powers fostered relationships with various members of the ashrāf, the Fā?imid–ashrāf dynamics were distinctive in that the Fā?imids legitimised their rule as Ismā?īlī Shī?ī imām-caliphs, based on their claim of descent from the Prophet Mu?ammad, and as the sole successors to his authority and leadership over the Islamic world. Consequently, Fā?imid–ashrāf relations were permeated by fraternal camaraderie as well as by competing contestations based on their shared claim to Prophetic lineage.     

Shi‘ism and the Early Dinars of the Fāṭimid Imam-caliph al-Mu‘izz li-dīn Allāh (341–365/952–975): An Analytic Overview

The Imam-caliph al-Mu‘izz al-Dīn Allāh undertook a series of monetary changes which were to have a monumental impact on all future Fā?imid coinage, would lead to many imitations even after the dynasty had fallen, and create an easily identifiable pattern that attracted medieval merchants and modern collectors. The fact that al-Mu‘izz's coinage went through three stages with slight variations in the wording and layout indicates that he was determined to create a new model for Fā?imid coinage which would distinguish it from the Aghlabid and ‘Abbāsid coinage that preceded and competed with it. In contrast, Sijilmasa coinage was so conservative in layout due to its role in the African trade.     

一个带协变量调整多响应比较的高效方法及其在基因组数据中的应用

目前在文献中有很多关于多响应比较的研究方法,但是对带协变量调整的非参数检验的研究较少。一种直观的想法是将数据先投影到协变量的正交空间中,然后再利用秩和检验、调整的秩和检验或最大值检验方法。但是,功效普遍不高。在调整的秩和检验和伪F检验两种方法基础上,构建MIN2检验。大量模拟和实际数据表明,MIN2检验的效果优于现有的非参数检验方法。     

Reprint requesting: A possible adjunct to citation analysis for judging research: Preliminary questions and findings

Interest in the quality of published research is evident across the range of disciplines including education. Several comprehensive studies either sponsored or published by the American Educational Research Association attest to this fact. In the sciences, citation analysis is attracting interest as a methodology for assessing research. The procedure has both theoretical and practical promise. The present study considers an overlooked source of information, reprint requesting, as a possible adjunct to citation analysis. The study stems from the questionnaire responses of 24 reprint requestors for an article by the authors. Requestor characteristics, motives, and reprint uses are considered. Implications for further research are advanced.
