No full textThis article discusses the book Metodología de la investigación en la enseñanza-aprendizaje del español como segunda lengua (L2)/lengua extranjera (LE), edited by Isabel Santos Gargallo and Susana Pastor Cesteros. The volume offers a broad overview of research methods in applied linguistics, specifically in the teaching and learning of Spanish as a foreign or second language. In addition, it includes some reflections on the dissemination and sharing of research findings
Complessi di oro con leganti imidazolici di interesse farmacologico
No full textL'imidazolo gioca un ruolo importante nella chimica biologica, difatti costituisce un componente laterale dell'istidina, amminoacido essenziale, e si trova anche in molte proteine.
Nel nostro gruppo di ricerca da anni ci si occupa della sintesi di complessi con leganti eterociclici azotati, con metalli di transizione come oro, platino e palladio, sia con scopi catalitici che con scopi farmaceutici.
Nello specifico il mio lavoro si e basato sulla sintesi di complessi di oro(I) e oro(III) con leganti contenenti anelli imidazolici
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
A importância das empresas de consultoria no setor hoteleiro
Get PDFO setor turístico e hoteleiro em Portugal, são atividades económicas de grande relevância, uma vez que geram grande riqueza e emprego para o país. Nos últimos anos estes setores têm estado sujeitos a diversas dificuldades e desafios, por este motivo as unidades hoteleiras têm vindo a necessitar de ajudas através das empresas de consultoria. A consultoria consiste num serviço de aconselhamento especializado em determinada área, por um especialista/consultor dessa mesma área, com o intuito de orientar o cliente a atingir os seus objetivos e a otimizar os seus resultados. As empresas de consultoria no setor hoteleiro, tendem a oferecer serviços nas áreas de marketing e vendas, revenue management, financeira (análise de rácios, controlo de custos…), estudos de mercado, estudo de viabilidade económico-financeira, formação/recursos humanos, contabilidade, auditorias, certificação de qualidade… Através desta dissertação foi possível compreender que os hotéis independentes acabam por ter maior tendência em recorrer a serviços de consultoria e que os serviços de consultoria mais procurados acabam por ser nas áreas de marketing e vendas, revenue management, recursos humanos, estudos de mercado e auditorias.The tourism and hotel sector in Portugal are economic activities of great relevance, since they generate great wealth and employment for the country. In recent years these sectors have been subject to various difficulties and challenges, for this reason the hotel units have been in need of help through consulting companies. The consultancy consists of a specialized advisory service in a certain area, by a specialist / consultant of that same area, in order to guide the client to achieve their goals and optimize their results. Consulting companies in the hotel sector tend to offer services in the areas of marketing and sales, revenue management, financial (ratio analysis, cost control...), market studies, economic and financial feasibility study, training/human resources, accounting, audits, quality certification...Through this dissertation it was possible to understand that independent hotels end up having a greater tendency to resort to consulting services and that the most sought after consulting services end up being in the areas of marketing and sales, revenue management, human resources, market studies and audits
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
