Job satisfaction and psychological wellbeing in bio-medical researchers
No full textIntroduction, The aim of the stuay was to assess job satisfaction and risk of depression/anxiety in researchers of a Research Institute in Rome. Methods. The personnel was invited to participate in a survey filling in the General Health Questionnaire (GHQ-12) for the screening of depression/anxiety disorders and the evaluation of psychological stress, and a validated satisfaction questionnaire. Results. A descriptive analysis was conducted and logistic regressions were performed examining the following outcomes in separate models: being positive at the GHQ and being satisfied. The response rate was 52%. Among participants 15.1% were at risk of depression/anxiety, 77.4% were stressed and 66% were dissatisfied. Major determinants for dissatisfaction were "job opportunities", "communication between Units", "judgment about spaces", "economic rewards", "participation in the organization of the Unit". Conclusions. Dissatisfaction with "economic rewards" was predictive of depression, independently of sex, age and job duration. Areas of possible intervention were identified. © PI-ME. Pavia 2010
Prevalence of psoriatic arthritis and joint complaints in a large population of Italian patients hospitalised for psoriasis
No full textWe investigated the prevalence of psoriatic arthritis and joint complaints in a large population of Italian patients hospitalised for psoriasis. A total of 936 patients were evaluated for psoriatic arthritis according to the European Spondyloarthropathy Study Group (ESSG) criteria. They were visited by a dermatologist who evaluated specific joint signs and symptoms (i.e. arthralgia, stiffness, swelling, ankylosis, paresthesia) and assessed skin disease severity. Information on socio-demographic variables and other factors of clinical interest was also collected. Seventy-one patients (7.7% of the sample) had psoriatic arthritis (PsA). Overall, 90% of patients with PsA referred arthralgia, 70.4% stiffness, 67.7% swelling, 25.4% paresthesia, and 23.9% had ankylosis. However, among patients with plaque psoriasis who did not fulfil the criteria for PsA, 12.3% referred paresthesias, 7% arthralgia, 4.2% stiffness, 3.7% swelling, and 1.2% had ankylosis. Among 114 patients referring arthralgia, 42 (39.6%) did not meet the ESSG criteria for PsA. Therefore, patients with plaque psoriasis refer joint symptoms quite frequently making it difficult to distinguish patients with psoriatic arthritis from patients with joint complaints
Severe impairment of quality of life in Hailey-Hailey disease.
No full textHailey-Hailey disease ( a skin fragility disorder) runs a chronic course and may cause important disability. However, little has been formally investigated concerning the quality of life (QoL) of patients affected by this disorder. We studied the impact of Hailey-Hailey disease on the QoL of 22 consecutive patients seen at our dermatological clinic. Patients were examined by a dermatologist, and they were asked to complete two self-administered questionnaires: the Skindex-29, in order to determine their QoL, and the 12-item General Health Questionnaire, to evaluate psychological distress. Completed questionnaires were returned by 20 patients. Even in patients with few body sites involved, median overall QoL scores were much higher than those observed in other skin conditions in all three domains investigated by the Skindex-29 (i.e. symptoms, emotions and social functioning). This was true also for the levels of psychological distress. QoL impairment was substantial irrespective of the number of body sites involved. Our findings document a great impact of Hailey-Hailey disease on patients' QoL. Therefore, a more aggressive therapeutic approach may be warranted in all patients, including those with few lesions
Psychometric properties of the Dermathology Life Quality Index (DLQI) in 900 Italian patients with psoriasis
No full textThe Dermatology Life Quality Index (DLQI) is one of the most frequently used questionnaires to evaluate the impact of dermatological diseases on patients’ lives. This study aimed to assess the reliability and validity of the instrument and to test its unidimensionality in a large sample of patients with psoriasis (n=976) hospitalized at IDI-IRCCS, Rome, Italy. Nine hundred patients completed the DLQI, the Psoriasis Disability Index (PDI) and the Skindex-29 (response rate 92%). The internal consistency of the DLQI was high (Cronbach’s alpha=0.83). Evidence of convergent validity was provided by high (r=0.64–0.81) correlations between the DLQI, the PDI, and the functioning and emotions scales of Skindex-29. Exploratory factor analysis indicated the presence of four different principal common factors. Confirmatory factor analysis showed a clear second-order factor structure, with a homogeneous second-order factor underlying the four primary-surface factors. This study confirms that the DLQI is a reliable and valid instrument to assess patient-perceived impact of skin disease. Also, it supports the unidimensionality of the DLQI and hence corroborates the common practice of using the total score
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
