No full textPositioning Climate Therapy Stays as a Health Tourism Product: An Evidence-Based Approach
Full text linkBackground: The relationship between Length Of Stay (LOS) and Metres Above Sea Level (MASL) of Climate Therapy Stays (CTSs) and their therapeutic effectiveness and efficiency has been under-researched in the last four decades. As a consequence, the potentials of short-term and low-altitude CTSs remain unknown. Objectives: The purpose of this study is twofold. Firstly, it aims to ascertain whether LOS and MASL are related to the percentage change of Forced Expiratory Volume in 1 second (FEV1) and the percentage change of FEV1 Compound Daily Improvement Rate (FEV1 CDIR % Change). Secondly, it aims to provide an evidence-based positioning of CTSs by considering the same specific variables. Methods/Analysis: The study focuses on young people (age ˂18) who have asthma problems. The Resource-Based Theory, postulating the valuability of natural resources generating above-average benefits, has been adopted as a conceptual lens. Primary studies carried out in eastern and western European countries and separately reviewed have been considered jointly. Spearman’s rank correlation coefficient was used to determine the relationship between LOS and MASL of CTSs with FEV1Change (%) and FEV1Change CDIR (%) as indicators of health improvements. The descriptive statistics were implemented in calculating standardized and aggregated values. Findings: Negative and significant relationships have been highlighted between FEV1 Change (%) and MASL and between FEV1 Change CDIR % and LOS. In other words, subjects can achieve significant health improvements even by experiencing very short climate therapy stays at very low altitude mountain centres. Considering the FEV1Change (%) and the FEV1 Change CDIR (%) of climate stays by duration and elevation, the evidence-based knowledge platform has been established as a possible framework for developing an evidence-based marketing strategy for new health tourism products. Novelty/Improvement: Notwithstanding the need for further research, the metrics facilitating interdisciplinary, human health and economic studies have been devised. Further research on the effects of low altitude climate therapy stays could help define the healing potentials of macro and microclimatic conditions as potentially valuable ‘health devices’ for those suffering from respiratory diseases living in the COVID-19 era. Quantifying these effects through further studies, an evidence-based approach to formulating marketing strategies may be devised, useful both for supporting public health provision and policies, and for facilitating practitioners in health tourism interested in offering nature-based activities for their clients
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
‘Antico/Nuovo’,’ Nuovo/Antico’: la difficile convivenza con la memoria. Riflessioni sull’eredità storica della disciplina del restauro
No full textNell’ambito del restauro, parlare di “Antico/Nuovo” induce a interrogarsi su quale riferimento – o su quali riferimenti concettuali – sia da porre la questione: se rispetto al tempo, alla storia, o alla materia, o alla tecnica, o alla memoria. O ancora, all’arte. La vicenda del restauro ha mostrato tutta l’ambivalenza di cui è carico l’ineluttabile confronto tra ciò che preesisteva e ciò che si aggiunge nel corso del tempo a un edificio. Seguendo alcune possibili combinazioni dei due termini ‘Antico’ e ‘Nuovo’, quasi come in una sorta di calcolo fattoriale - il contributo intende ripercorrere, attraverso la vicenda storica del restauro, le modalità attraverso le quale il rapporto antico/nuovo – consostanziale alla natura stessa della disciplina – si è posto in relazione al mutare delle culture, e con esse all’evoluzione degli strumenti critici e operativi che in termini concreti si misurano con i temi cruciali del rapporto tra presente e passato sul terreno comune del cantiere
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
