No full textBackground: The most common mental disorders in women during the perinatal (antenatal and postnatal) period are depressive syndromes and anxiety syndromes. The global prevalence of maternal perinatal depression ranges from 10 to 20%, while the prevalence of perinatal anxiety ranges from 10 to 24%. The comorbidity of mood and anxiety disorders in perinatal women is common, reaching 40%. In Italy, a few studies have been undertaken to evaluate the prevalence of perinatal depression and anxiety, and there is still a scarcity of research and intervention programs regarding primary prevention. Three of the main aims of this study are: (1) to evaluate the prevalence of maternal perinatal depression and anxiety in a large sample of women attending healthcare centers in Italy; (2) to investigate the psychosocial risks and protective factors associated with maternal perinatal depression and anxiety; (3) to evaluate the effectiveness of a manualized psychological intervention (Milgrom et al., 1999) to treat perinatal depression; (4) to evaluate the psychometric properties of both the Edinburgh Postnatal Depression Scale and the Patient Health Questionnaire-9 in detecting perinatal depression; and (5) to evaluate the influence of maternal depression and anxiety on the development of infant temperament. Methods: This is a prospective cohort study, which merges an observational design and a pre-post intervention design. The study includes a 1-year recruitment period and a one-year follow-up period. The methodological strategy includes: (1) self-report questionnaires on maternal depression, anxiety, health status, quality of life and psychosocial risks; (2) a self-report questionnaire to measure the infant’s temperament; (3) a clinical interview; (4) a structured diagnostic interview; and (5) a psychological intervention. Discussion: The results of this study may contribute to our knowledge about prevalence of antenatal and postnatal depression and anxiety (during both the trimesters of pregnancy and the first six trimesters after birth) and about the effectiveness of early psychological intervention in the perinatal health services
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
C11 vs C9 carbamoylation of quinine: a new class of versatile polyfunctional chiral solvating agents
No full textCarbamoyl derivatives of quinine obtained by derivatization of its double bond have been prepared and used as chiral
solvating agents for NMR spectroscopy: their efficiency reproduces very well that of quinine and its C9 carbamates in

No full textVariations 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
Fractured carbonate aquifers of Sibillini Mts. (Central Italy)
No full textThe aim of the present map is to illustrate a detailed pre-earthquake hydrogeological conceptual model of the Sibillini Mts. This area was struck by a prolonged seismic sequence of up to Mw 6.5 in 2016. Geological, tectonic, and hydrogeological data were collected from the literature before 2016, subsequently standardized and re-interpretated with the aim of presenting a hydrogeological map (1:50,000 scale) of the Sibillini Mts. carbonate system (Central Italy). The map is supported by 11 hydrogeological both cross and longitudinal sections, which show the underground spatial relationship between aquifers, aquicludes, and tectonic elements. This Map provides a model of comparison for the new hydrogeological conditions emerging from the post-seismic research
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
