Persistent negative symptoms in young people at clinical high risk of psychosis treated with an Italian early intervention program: a longitudinal study
Full text linkNegative symptoms in CHR-P people are generally not responsive to treatments and commonly related to poorer functional
outcome. However, less research attention has been dedicated to Persistent Negative Symptoms (PNS), defined as clinically
stable negative symptoms of moderate severity evident for at least 6 months. This study aims to (a) determine the prevalence
of PNS in a sample of young people at CHR-P; (b) investigate any association of PNS with functioning and clinical features;
(c) examine longitudinal course of PNS across 2 years of follow-up and changes in PNS severity levels with specialized
treatments. One Hundred Eighty CHR-P participants were recruited and were divided into CHR-P/PNS + and CHR-P/PNS−
subgroups. The clinical assessments were based on the PANSS and the GAF and were conducted at baseline and every
12 months during the follow-up. Twenty four participants showed PNS at entry. Of them, 21 concluded the 2-year followup
period. At baseline, the CHR-P/PNS + participants showed more educational and employment deficits, and more social
and functioning impairment. During the follow-up, the CHR-P/PNS + subgroup had a significant longitudinal decrease in
negative symptoms, which was specifically related to antidepressant treatment. CHR-P/PNS + subjects also showed a higher
incidence of new hospitalization and a lower functional recovery over time. Our findings support that the persistence of
negative symptoms in CHR-P people is longitudinally related to worse daily functioning and more severe clinical conditions
that are at higher risk of hospitalization and are less responsive to specialized treatments
Suicidal thinking and behavior in young people at Clinical High Risk for Psychosis: Psychopathological considerations and treatment response across a 2-year follow-up study
No full textIntroduction: Suicidal ideation has high rates among individuals at Clinical
High Risk for Psychosis (CHR-P). CHR-P mental states are currently defined as
attenuated psychotic symptoms, brief intermittent psychotic symptoms, or genetic risk and functioning deterioration syndrome. However, the relationship
between psychotic experiences and suicidality in CHR-P subjects is still not fully
understood. Research emphasizes the need to address suicidality in CHR-P individuals due to its incidence and severe socio-economic impact. This study aimed
to assess the baseline prevalence and 2-year incidence rates of suicidal thinking
and behaviors in an Italian CHR-P sample, investigate the stability of suicidal
ideation over 2 years, and examine its associations with treatment outcomes, sociodemographic characteristics, and clinical factors.
Methods: CHR-P participants were treated in an “Early Intervention in
Psychosis” program and completed the PANSS and the GAF scale at baseline and
every 12months.
Results: 180 CHR-P individuals were enrolled (92 with suicidal ideation [SI+]).
SI+ subjects had a higher baseline prevalence of past suicide attempts. Over
2 years, a decrease in suicidal ideation severity was observed in the total group.
Longitudinal improvement in disorganized symptoms was a key predictor of the
decrease in suicidal ideation. Participants with a history of suicide attempts were
more likely to attempt again.
Conclusion: Addressing disorganization is crucial for suicide prevention in
the CHR-P population. Continuous risk monitoring and preventive actions are
needed for those with past suicide attempts
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
