Some heat islands
No full text‘Bloody Queensland, a new heatwave warning every week!’ reads a reply on an ABC emergency alert recalling the old Queensland tourism slogan, ‘beautiful one day, perfect the next’. It’s Saturday 11 February 2023, Tropical Cyclone Gabrielle, or is it tc Gabbie?, tc Gabs?, is threatening ruin on Norfolk Island but has merely brought a heatwave to South East Queensland — low intensity.Full Tex
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Some Europeans are more equal than others
No full textThe position of Roma migrants in the EU presents an anomaly which challenges the foundations of European Union law. As Union citizens, European migrants are entitled to freedom of movement and residence in Member States. Yet the rights intended to secure this position have been routinely and selectively denied to Roma migrants, leading to forced evictions and collective expulsions without regard t o European Law. As has been evidenced in the UK, Roma arrivals are viewed with particularly acute suspicion; a response which reflects their double stigmatization as both immigrant and Roma. At the same time, Roma migration from new Member States has expo sed a contradiction inherent in the citizenship project which strikes at the heart of the Union ’s human rights credentials. The degree of exclusion and inequality faced by Europe’s largest minority in all Member States is the most pressing internal human rights issue facing the EU. Yet the European institutions continue to lack a coherent response and defined strategy. The current European framework demanding National Action Plans is commendable in that it prevents individual states from abdicating responsibility for the situation of their Roma citizens. Nevertheless, the absence of clear targets, Roma engagement and European leadership, suggest that this strategy is doomed to failure offering little more than a distraction. In a Union predicated on, inter alia, the rule of law, respect for human rights and the protection of minorities, this detached position undermines the legitimacy of the entire citizenship project
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Fully Turbulent Mean Velocity Profile for Purely Viscous non-Newtonian Fluids
No full textThe characteristic near wall behavior of turbulent flow of purely-viscous non-Newtonian fluids is discussed for both power-law (P.-L.) and Herschel-Bulkley (H.-B.) rheological models. A proper scaling is presented for H.-B. fluids to establish an analogy with power-law fluids with same flow index. To provide reference data for turbulent flow of non-Newtonian fluids, DNS simulations of power-law fluids are conducted in a rectangular channel for a large range of power-law indices ( = 0.5, 0.69, 0.75, 0.9, 1, 1.2). The DNS data show that the mean velocity profile in the viscous and logarithmic layers follow expressions of the form and respectively, where shows a logarithmic dependency on the flow index.Comparison with some experimental data shows the above formulation to be valid for Reynolds numbers (based on shear velocity) as high as 1000
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Author-level metrics: h-index and beyond
No full textAuthor-level metrics are usually employed for academic promotion and research funding. The h-index is a way of measuring scientists’ productivity and impact on their field, determined by the number of publications and the number of times those publications have been cited. However, the h-index calculation does not capture the influence of factors such as research topics, article types, highly cited items, self-citations, number and position of authors, and academic career length. Nonetheless, variants of h-index that address some of these limitations correlate widely with their original metric, are not available in bibliographic databases and, overall, add little for measuring research productivity
A Survey of Quality Engineering-ManagementJournals by Bibliometric Indicators
No full textThis paper analyses some of the most popular scientific journals in the Quality field from the point of view of three bibliometric indicators: the Hirsch (h) index for journals, the total number of citations and the h-spectrum. In particular, h-spectrum is a novel tool based on h, making it possible to (i) identify a reference profile of the typical authors of a journal; (ii) compare different journals; and (iii) provide a rough indication of their ‘bibliometric positioning' in the scientific community. Results of this analysis can be helpful for guiding potential authors and members of the scientific community in the Quality Engineering/Management area. A large amount of empirical data are presented and discusse
