Alla ricerca di una spiegazione non circolare delle riforme economiche. Elementi per una nuova teoria individualista del cambiamento istituzionale.
Get PDFRational-choice explanations of institutional change are generally considered the prototype of the individualistic research programme. The first aim of the paper is to demonstrate that this claim is not warranted. It is not so if the phenomena to be explained are defined from the external point of view of social efficiency: in this case, individualism is transformed into functionalism and the notions of its toolbox are turned into elements of an objective teleology. When considered from the point of view of the individuals involved in their construction, institutions can be conceived as repeated cooperation schemes devised by some of these individuals (the proposers) as the best means to tackle the mutual dependences in which they find themselves and achieve some of their goals, and adopted in mutual agreement with their counterparts (the receivers) because convenient for them too, given their own particular interests. The second aim of the paper is to develop a bargaining model based upon this idea. The proposed model shows, among other things, that when bargaining concerns the adoption of repeated cooperation schemes (i.e. of institutions, according to my definition), it is in the interest of the proposers to get to correct (or so considered) beliefs and to communicate them to the counterpart sincerely. Moreover, when bargaining consists in choosing one scheme among others, it is possible that some will agree to it despite the fact that they are not better-off with respect to the initial situation. The third aim of the paper is to show that the model proposed can highlight the process that has led to adopt important institutions such as the European Monetary System
Oxidative stress and brain diseases: Biomarkers and analytical methodologies
No full textOxidative stress is the imbalance between production of reactive oxygen species (ROS) and ability of the biological systems to readily detoxify the reactive intermediates or to repair the resulting damage. Disturbances in the normal redox state of tissues can cause toxic effects through the production of peroxides and free radicals that damage all components of the cell including proteins, lipids and DNA. Furthermore, some ROS can even act as messengers through a phenomenon called redox signaling. In humans, oxidative stress is involved in many pathogenic mechanisms triggering aging processes and affecting organs as liver and brain. In the present paper, the role of oxidative stress is considered in relation to three neurodegenerative pathologies those are the most common in western countries and have analogies in brain damages notwithstanding different etiologies: i) Alcohol abuse by environmental etiology, ii) Down Syndrome by genetic etiology, and iii) Alzheimer's disease by age-related etiology. Recent studies have described the results about application of different biomarkers of oxidative stress to study these brain pathologies. The present paper deals with the diagnostic applications of the oxidative-stress biomarkers like malondialdehyde. heat shock protein. ROS and retinol binding protein in clinical handling of patients and discusses their diagnostic power taking into account cost/benefit ratio too

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
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
