Journal ranking should depend on the level of aggregation

Journal ranking is becoming more important in assessing the quality of academic research. Several indices have been suggested for this purpose, typically on the basis of a citation graph between the journals. We follow an axiomatic approach and find an impossibility theorem: any self-consistent ranking method, which satisfies a natural monotonicity property, should depend on the level of aggregation. Our result presents a trade-off between two axiomatic properties and reveals a dilemma of aggregation.

基于真值表搜索的逻辑函数自动化简方法

研究逻辑函数的化简方法具有重要理论价值和实际工程意义。基于真值表和卡诺图的等价性,本文提出一种基于真值表搜索的逻辑函数自动化简方法。在穷举搜索真值表中最小项组基础上,通过检查和合并而实现逻辑函数的自动化简。该方法不受变量数目限制,易于编程,为多变量数字系统的自动化设计提供了一条有效的系统化解决途径。     

The use of material transfer agreements in academia: A threat to open science or a cooperation tool?

The transfer of scientific material and data, which are scientific inputs, is fundamental to knowledge creation dynamics. This transfer is being controlled, more and more, by the use of Material Transfer Agreements (MTAs). Therefore, the effect of MTAs on the dynamic of knowledge creation is an important concern. The aim of this research is to characterise the restrictions imposed by MTAs, and their determinants. We consider MTA diversity based on a comprehensive analysis of the clauses included in 171 MTAs signed by two French universities. We show that the clauses included in MTAs depend on several factors such as kind of material involved, research field, patenting and collection of material. We find that the presence of an industry actor is not associated to more restrictions on publication and intellectual property. We propose a typology of MTAs corresponding to different transfer situations. We discuss the role of MTAs as collaborative tools and the influence of the legal, scientific, political and organisational context.
