Should Top Universities Be Led By Top Researchers and Are They? A Citations Analysis

[Excerpt] This paper addresses the question: should the world’s top universities be led by top researchers, and are they? The lifetime citations are counted by hand of the leaders of the world’s top 100 universities identified in a global university ranking. These numbers are then normalized by adjusting for the different citation conventions across academic disciplines. Two statistical measures are used -- Pearson\u27s correlation coefficient and Spearman\u27s rho. This study documents a positive correlation between the lifetime citations of a University’s president and the position of that university in the global ranking. Better universities are run by better researchers. The results are not driven by outliers. That the top universities in the world -- who have the widest choice of candidates -- systematically appoint top researchers as their vice chancellors and presidents seems important to understand. This paper also shows that the pattern of presidents life-time citations follows a version of Lotka’s power law. There are two main areas of contribution. First, this paper attempts to use bibliometric data to address a performance- related question of a type not seen before (to the author’s knowledge). Second, despite the importance of research to research universities -- as described in many mission-statements -- no studies currently exist that ask whether it matters if the head of a research university is himself or herself a committed researcher. Given the importance of universities in the world, and the difficulty that many have in appointing leaders, this question seems pertinent

Rethinking authenticity in digital art preservation

In this paper I am discussing the repositioning of traditional conservation concepts of historicity, authenticity and versioning in relation to born digital artworks, upon findings from my research on preservation of computer-based artifacts. Challenges for digital art preservation and previous work in this area are described, followed by an analysis of digital art as a process of components interaction, as performance and in terms of instantiations. The concept of dynamic authenticity is proposed, and it is argued that our approach to digital artworks preservation should be variable and digital object responsive, with a level of variability tolerance to match digital art intrinsic variability and dynamic authenticity

Achieving the state of research pertaining to GIS applications for cultural heritage by a systematic literature review

During the last decade, we have witnessed an increased interest in Geographic Information Systems (GIS), including the so-called “Historical GIS”, 3D GIS heritage and its subcategory of “SDI for cultural heritage”. Specific literature reviews, gathering and analysing the scientific production for Culture Heritage and GIS based research questions, are currently lacking. Therefore, the overall goal of this article is to provide an objective summary of the current state -of-the-art concerning how GIS has been used and what methods and analysis have been applied in the field of cultural heritage. In this sense, a Systematic Literature Review (SLR) of the literature on the application of GIS in cultural heritage is carried out. To do so, the WOS and Scopus databases were considered. The results show that the dominant application of GIS is in the realisation of inventory and cataloguing of archaeological and architectural heritage. As a result of the quantitative analysis, we also verify the principal sources in which most studies have been published, highlighting the "ISPRS Archives" with 14 publications, the "Lecture Notes in Computer Science" with 9, and "Proceedings of Digital Heritage" with 6 publications. These data show that the sources that most publis h mainly belong to the field of IT and Computer Science. In addition, the SLR shows that in the last three years there has been a greater tendency to use GIS to solve more specific problems of heritage through its use in conjunction with other tools such as BIM and photogrammetrySpain’s Ministry of Economy and Competitiveness HAR2016–78113-R HAR2016–76371-
