No full textThe question addressed to in this paper is whether severely mentally ill patients are treated differently in a community mental health service without the back-up of a mental hospital (South-Verona, Italy) compared with an institution-based system in which mental hospitals, although highly modernized, are still predominant (Groningen, The Netherlands). Using the psychiatric case-registers in both areas, the patterns of care in 2 years of follow-up of schizophrenic patients were constructed. Survival analysis was used to analyse in-, day- and out-patient episodes of care. Three-quarters of the Groningen and half of the South-Verona patients experienced at least one episode of hospitalization; 20% of the Groningen and 5% of the South-Verona patients were long-stay patients at the end of the observation period. The South-Verona patients had more episodes of in-patient and especially of day-patient and out-patient care. Cox's regression showed that the duration of episodes controlled for the history of events and sociodemographic characteristics, was significantly shorter in South-Verona. One of the main conclusion was that hospitalizations for the severely mental ill are also needed in a community-based system of care, supporting the assumption of a 'bed-rock' of mental illness. However, the South-Verona community mental health service seems to be able to reduce the duration of hospitalizations considerably
Patterns of psychiatric care in South Verona and Groningen. A case register follow up study
No full textContinuity of care for patients with schizophrenia and related disorders: a comparative South-Verona and Groningen case-register study
No full textBackground. It is widely believed that for the severely mentally ill continuity of care is essential to ensure a better outcome and prevent long-term hospitalization. However, not much progress has been made in the operationalization and measurement of this concept. We used two indicators to compare continuity of care of schizophrenic patients in two kinds of mental health systems. One is a community mental health system without the back-up of a mental hospital (South-Verona, Italy). The other is an institution-based system in which mental hospitals are still predominant (Groningen, The Netherlands). Methods. The first indicator of continuity of care, readiness of aftercare, is the time from discharge from hospital to the first day-or out-patient contact. Survival analysis was applied to correct for censored observations. The second indicator, flexibility of care, is the use of combinations of in-, day-and out-patient care during 2-year follow-up. Results. More patients in South-Verona received community care within 2 weeks after discharge (71.5%), than in the Groningen register area (54.6%). The survival functions differed significantly. Cox regression analysis revealed that in both systems a contact before admission, the time between this contact and admission and the duration of the admission are predictors for aftercare. A higher percentage of patients made multiple service use (combinations of in-, day-and out-patient care) in South-Verona than in Groningen (62 v. 45%). Conclusions. Both indicators showed a higher continuity of care in the South-Verona system
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
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
