Uniqueness of extremals for some sharp Poincar\'e-Sobolev constants
No full textWe study the sharp constant for the embedding of into
, in the case . We prove that for smooth connected sets,
when and is sufficiently close to , extremal functions attaining
the sharp constant are unique, up to a multiplicative constant. This in turn
gives the uniqueness of solutions with minimal energy to the Lane-Emden
equation, with super-homogeneous right-hand side.
The result is achieved by suitably adapting a linearization argument due to
C.-S. Lin. We rely on some fine estimates for solutions of Laplace--type
equations by L. Damascelli and B. Sciunzi

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
Dravidian dataset for the Lindgren (2023) study
No full textDataset on Dravidian languages, focusing on Tulu, accompanying the master's thesis of Lindgren (2023). Includes data from the author's fieldwork, contributions from other authors, and data adapted from the Kolipakam et al. (2018) study.
The author collected a set of lexical items for comparative analysis to address the classification of Tulu, Koraga, and Bellari within the Dravidian language family. This dataset included 114 comparative concepts previously collected for the study of Bellari (Bhat, 1971), the Leipzig-Jakarta list of lexical items, a subset of the 100-word Swadesh list not present in the Leipzig-Jakarta list, and counting words from 1 to 10, and a more extensive list of pronouns, totalling 231 comparative concepts. Word lists were gathered from various sources, including grammars and dictionaries, for Bellari (Bhat, 1971), four Koraga varieties (Onti, Tappu, and Mudu from Bhat, 1971; Ande from Shetty, 2008), Kannada (Kittel, 1894; Učida, Rajapurohit & Takashima, 2018; Spencer, 1950; Zydenbos, 2011; Sridhar, 1990), Malayalam (Moag & Moag, 1967; Asher & Kumari, 1967; Sudha, 1984; Jiang, 2010), Tamil (Borin et al., 2013), Byari (Upadhyaya, 2011), and Pattapu (IRA, 2013), and three Tulu varieties. The Tulu word lists included those from M. M. Bhat (1967), a dictionary of Tulu including words from multiple dialects, a Madhwa Brahmin wordlist collected from Bhatt (1971), and a wordlist from data collected through the author's fieldwork. Data for several other languages, namely Telugu, Koya, Kolami, Gondi, Parji, Ollari Gadba, Kuwi, Kurukh, Malto, Brahui, Yeruva, Kodava, Badga, Toda, Kota, and Betta Kurumba, were included from Kolipakam et al. (2018), as well as additional data for Kannada, Malayalam, Tamil, and Tulu from the same source. The latter’s Kannada, Malayalam, Tamil, and Tulu wordlists were added as separate doculects.
Concepts not given in Concepticon are marked by an initial asterisk (e.g., "*BETEL LEAF"). Most of these are concepts distinguishing pronouns in the languages, such as marking distinctions between remote and proximate (e.g., "*3SG.I.R" and "*3SG.I.P"), which the author considered essential for comparing the languages also due to the conservativeness of some forms and phonemes (e.g., the presence of /a/ for remote and /i/ for proximate in most languages). The labels for pronoun concepts not given in Concepticon are built with the following constituents:
"2SG" : second singular
"3PL" : third plural
"3SG" : third singular
"A" : animate
"F" : female
"H" : honorific
"I" : inanimate
"M" : male
"P" : proximate
"R" : remote

Continuity of solutions to a nonlinear fractional diffusion equation
No full textWe study a parabolic equation for the fractional p-Laplacian of order s. for p >= 2 and 0 < s < 1. We provide space-time Holder estimates for weak solutions, with explicit exponents. The proofs are based on iterated discrete differentiation of the equation in the spirit of Moser's technique
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
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
Asymmetric Information and the Demand for Voluntary Health Insurance in Europe
No full textSeveral past studies have found health risk to be negatively correlated with the probability of voluntary health insurance. This is contrary to what one would expect from standard textbook models of adverse selection and moral hazard. The two most common explanations to the counter-intuitive result are either (1) that risk-aversion is correlated with health — i.e. that healthier individuals are also more risk-averse — or (2) that insurers are able to discriminate among customers based on observable health-risk characteristics. We revisited these arguments, using data from the Survey of Health, Ageing and Retirement in Europe (SHARE). Self-assessed health served as an indicator of risk: better health, lower risk. We did, indeed, observe a negative correlation between risk and insurance but found no evidence of heterogeneous risk-preferences as an explanation to our finding.
The Australian Asbestos Network – how journalism can address a public health disaster
No full textAsbestos presents an ongoing health disaster worldwide. First through mining and manufacturing, and now through workplaces and the home, exposure to asbestos is presenting a public health hazard that will continue well into the 21st century. Yet it is a hidden epidemic with litigation often silencing the voices that could attest to the destructive impact of what was once called the ‘magic mineral’. This paper describes a unique collaboration between journalists, doctors and public health researchers where journalistic techniques are used to bring the peoples’ stories of suffering and caring to public attention. The project illustrates the value of interdisciplinary collaboration as well as demonstrating how journalistic activity can be the subject of legitimate academic research. The outcome is a website, with three functions: first, as an historical archive of asbestos stories through audio and video interviews with asbestos diseases sufferers, their families and carers; second, as a one-stop-shop for public health information about asbestos risk where journalism skills are employed to translate often complex information into accessible language and formats; and third, as the nucleus for a future online community where patients and doctors can interact and experiment with more collaborative models of medical and public health interventions
