The influence of lifestyle on airborne particle surface area doses received by different Western populations
Full text linkIn the present study, the daily dose in terms of particle surface area received by citizens living in five cities in Western countries, characterized by different lifestyle, culture, climate and built-up environment, was evaluated and compared. For this purpose, the exposure to sub-micron particle concentration levels of the population living in Barcelona (Spain), Cassino (Italy), Guilford (United Kingdom), Lund (Sweden), and Brisbane (Australia) was measured through a direct exposure assessment approach. In particular, measurements of the exposure at a personal scale were performed by volunteers (15 per each population) that used a personal particle counter for different days in order to obtain exposure data in microenvironments/activities they resided/performed. Non-smoking volunteers performing non-industrial jobs were considered in the study.Particle concentration data allowed obtaining the exposure of the population living in each city. Such data were combined in a Monte Carlo method with the time activity pattern data characteristics of each population and inhalation rate to obtain the most probable daily dose in term of particle surface area as a function of the population gender, age, and nationality.The highest daily dose was estimated for citizens living in Cassino and Guilford (>1000 mm2), whereas the lowest value was recognized for Lund citizens (around 100 mm2). Indoor air quality, and in particular cooking and eating activities, was recognized as the main influencing factor in terms of exposure (and thus dose) of the population: then confirming that lifestyle (e.g. time spent in cooking activities) strongly affect the daily dose of the population. On the contrary, a minor or negligible contribution of the outdoor microenvironments was documented
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Cognitive Semantics, Linguistic Typology and Grammatical Polysemy: "Possession" and the English Genitive
No full textThis paper explores the cognitive semantics of the typological category “possession” using the Natural Semantic Metalanguage (nsm) approach. At the macro level, we argue that “possession” is not a unitary cognitive category for speakers, but instead represents an aggregation of diverse semantic schemas which center around three distinct conceptual anchor points: ownership, body-parts, and kinship relations. It is shown how each of these conceptual anchor points can be clearly identified using the nsm metalanguage of semantic primes and molecules. At the micro level, the paper undertakes a close examination of the cognitive semantics of English s-genitives in the frame [THIS SOMEONE’S] SOMETHING, e.g. Mary’s ring, Mary’s shoes, Mary’s drawing, Mary’s plate, Mary’s train. It is argued that the wide range of use of the s-genitive can be captured in a set of five semantic schemas, which constitute a network of grammatical polysemy.No Full Tex
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
"We": conceptual semantics, linguistic typology and social cognition
No full textThis paper explores “we-words” in the languages of the world, using the NSM method of semantic analysis. A simply phrased, cross-translatable explication for English ‘we’ [1pl] is proposed, suitable also for other languages with a single we-word. At the same time, it is argued that English ‘we’ co-lexicalises a second distinct meaning “we two” [1du], and that the same goes for other languages with a single we-word. The two explications are identical, except for being based on ALL and TWO, respectively. Both explications involve components of “I-inclusion” (roughly, ‘I am one of them’) and “subjective identification” (roughly, ‘I'm thinking about them all in the same way’). It is argued, furthermore, that both meanings (“we-all” and “we-two”) are likely to be found in all languages. To establish this, one has to take account of languages which manifest the “inclusive/exclusive” distinction. For such languages, evidence suggests that one of the two we-words contains a semantic component of “you-inclusion”, while the other is semantically unmarked. Languages whose “we words” encode kinship relations are also briefly considered. The analysis has implications for the typology of pronoun systems, for theorising about human social cognition, and for the lexical semantics of key social concepts.We would like to thank Carsten Levisen, Zhengdao Ye and Bert Peeters for helpful feedback on an earlier version of this
study. We also received stimulating comments from participants at two Semantic Workshops held at the Australian National
University in 2018
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
