From prematurity to parenting stress: The mediating role of perinatal post-traumatic stress disorder
No full textPreterm delivery may lead to the emergence of symptoms of Post-Traumatic Stress disorder (PTSD), which may, in turn, affect the quality of the mother-child relationship. The aim of this study is to shed light on the development of parenting stress in mothers of preterm and full-term children. It is hypothesized that PTSD symptoms mediate the relationship between preterm/full-term birth and the levels of parenting stress. Perinatal PTSD, parenting stress and social support were assessed in 156 mothers of full-term children and 87 mothers of preterm children. Mothers of preterm children experienced more post-traumatic stress and parenting stress than mothers of full-term children. However, the relationship between preterm delivery and subsequent levels of parenting stress was mediated by PTSD symptoms. These findings suggest that the maternal perception of childbirth as a traumatic experience and the subsequent development of PTSD symptoms are pivotal in the emergence of parenting stress

The therapy of cervical adenopathies in tumors of the lip and oropharynx
No full textThe authors, after some notes of topographic anatomy about the lymph nodes of the cervical area, examine the different therapeutic managements of lymph node metastasis of lip and oropharynx carcinoma. From these data, the authors put in evidence that almost all the surgeons and the radiotherapists do agree about the inclusion of radiotherapy, polychemotherapy and, more often, surgery in the treatment of cervical lymph node metastasis. The authors experience suggests no treatment of the cervical region in case of N0 lower lip cancer, especially if the neck is thin, and easy to examine, but it is necessary a careful follow-up in order to discover as soon as possible a clinic metastasis. They do not exclude that this behaviour could be suggested also in other neoplastic disorders, but the decision should be based on the histologic kind and grading, on the extension and on the possibility to exclude any cervical involvement. Beside this, the authors come to the conclusion that, in case of N1, N2, N3, the treatment of the cervical regions can not be avoided. The surgical treatment is the neck dissection, functional or radical, alone or together with radiotherapy and polychemotherapy. They finally report that the postoperative radiotherapy for cervical metastasis must be properly used when the capsular rupture is histologically proved
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
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
Item Response Theory Analysis of the Life Orientation Test-Revised: Age and Gender Differential Item Functioning Analyses
No full textThis study is aimed at testing the measurement properties of the Life Orientation Test-Revised (LOT-R) for the assessment of dispositional optimism by employing item response theory (IRT) analyses. The LOT-R was administered to a large sample of 2,862 Italian adults. First, confirmatory factor analyses demonstrated the theoretical conceptualization of the construct measured by the LOT-R as a single bipolar dimension. Subsequently, IRT analyses for polytomous, ordered response category data were applied to investigate the items’ properties. The equivalence of the items across gender and age was assessed by analyzing differential item functioning. Discrimination and severity parameters indicated that all items were able to distinguish people with different levels of optimism and adequately covered the spectrum of the latent trait. Additionally, the LOT-R appears to be gender invariant and, with minor exceptions, age invariant. Results provided evidence that the LOT-R is a reliable and valid measure of dispositional optimism
Job satisfaction of health professionals
No full textHealth profession has been traditionally considered as one of those professions at risk for psychological distress. While remarkable interest has been devoted to the burn-out syndrome, only recently have scholars and policy makers begun to pay attention to the factors promoting health professionals' satisfaction and gratification. Aim of the present study was to investigate general and domain-specific job satisfaction among 906 physicians and nurses working in various Italian hospitals. The influence of four variables on job satisfaction was investigated: type of profession (physicians vs. nurses), job seniority, the desire to change job, and the desire to change work place. Participants' suggestions to improve their ward and to increase their personal satisfaction were collected through open-ended questions. Results showed that physicians were more satisfied with their job than nurses, and that senior professionals were more satisfied than junior professionals. General satisfaction for the ward was mostly associated with leadership satisfaction and satisfaction with relationships with colleagues and superiors; negative and modest correlations were found between job satisfaction and burn-out. A material improvement of the ward, more personnel and an improvement in the relationships among colleagues were reported more frequently as the most important factors in order to improve the ward functioning. Higher salary and more adequate shifts and work load were reported more frequently as the most important factors in order to increase personal job satisfaction
