THE AMERICAN PRAGMATIC TRADITION: A USEFUL TOOLKIT FOR INTERNATIONAL RELATIONS? THE CASE OF THE OBAMA ADMINISTRATION AND ITS FOREIGN POLICY
No full textIl presente lavoro di ricerca indaga i rapporti tra la disciplina delle Relazioni Internazionali (RI) e la tradizione filosofica americana del Pragmatismo (PP), focalizzandosi sui possibili contributi che quest’ultimo può fornire alle RI, guardando sia allo sviluppo del dibattito paradigmatico della disciplina sia alla dimensione delle politiche. In particolare, dopo aver fornito un quadro generale dei principi fondamentali del pragmatismo e averne evidenziato la positiva influenza sullo sviluppo della disciplina delle Relazioni Internazionali, il lavoro di ricerca si concentra sul tema del pragmatismo applicato alla dimensione della politica estera, qui concepita come sottolivello delle RI multifattoriale, multidisciplinare e nel quale l’agente/attore specifico assume un ruolo centrale. In linea con questa impostazione, la ricerca si concentra sull’elaborazione della politica estera del 44° Presidente americano, Barack Obama, mettendone in luce gli explanans, la cui applicazione viene poi testata nell’ambito di due casi-studio particolari: le relazioni degli Stati Uniti con Cuba, da un lato, e Israele, dall’altro. Attraverso l’analisi della letteratura esistente, in gran parte piuttosto recente, di documenti ufficiali rilasciati dall’Amministrazione Obama e dai discorsi ufficiali del Presidente stesso, il lavoro mira a dimostrare l’effettiva importanza del Pragmatismo sia per gli studiosi delle RI che per i policy-makers.This research work aims at addressing the relations between the discipline of International Relations (IR) and the American philosophical tradition of Pragmatism (PP), investigating the possible contributions PP can provide IR with, both at a theoretical and a policy level. In particular, once given an overview of the basic principles of PP and the positive inputs it can provide to the discipline of the IR, the research work addresses the issue of whether pragmatism can direct and explain the formulation of a foreign policy (FP) – conceived as the sublevel of IR which is actor-specific, agent-oriented, multifactorial, multilevel, and multidisciplinary. In order to do so, an interpretative actor perspective is adopted, and the foreign policy of former U.S. President Barack Obama is analyzed, focusing on the explanans of his foreign policy making and vision. Their application is then tested on two case-studies: U.S.-Cuba relations and U.S.-Israel relations, in the timeframe of the Obama Presidency. Through the analysis of the existing literature – some of which quite recent, official documents released by the Obama Administrations and speeches given by the President, the research work tries to demonstrate that PP can indeed constitute a useful tool-kit for both IR scholars and policy-makers
Neuropsychological correlates of schizotypy: a systematic review and meta-analysis of cross-sectional studies
No full textINTRODUCTION:
Cognitive deficits can precede the onset of psychotic episodes and predict the onset of the illness in individuals with schizotypy traits. In some studies, high levels of schizotypy were associated with impairments in memory, attention, executive functions, and verbal fluency. This review provides a more comprehensive understanding of cognitive impairments related to schizoytpy.
METHODS:
A systematic review of "schizotypy and neuropsychological measures" was conducted, and it retrieved 67 studies. All papers with case-control design showing means and standard deviations from neuropsychological measures were included in a meta-analysis (n = 40). A comparison between our finding and another metaanalysis with patients with schizophrenia-spectrum disorders [Fatouros-Bergman, H., Cervenka, S., Flyckt, L., Edman, G., & Farde, L. (2014). Meta-analysis of cognitive performance in drugnaive patients with schizophrenia. Schizophrenia Research. doi: 10.1016/j.schres.2014.06.034 ] was performed to study the similarities on the MATRICS domains between the two disorders.
RESULTS:
We found evidence of worse functioning of verbal and visual-spatial working memory, and of language in people with schizotypy or with schizotypal traits. Working memory deficit is present in both schizotypy and schizophrenia with larger effect sizes compared to other domains.
CONCLUSIONS:
Working memory deficit might be a cognitive marker of the risk of psychosis. Interventions targeting cognitive deficits early may be crucial to the prevention of psychosis
Oxytocin and autism: A systematic review of randomized controlled trials
No full textOBJECTIVE:
Little is known about the effectiveness of pharmacological interventions on autism spectrum disorder (ASD). This is a systematic review of the randomized controlled trials (RCTs) of oxytocin interventions in autism, made from January 1990 to September 2013.
METHOD:
A search of computerized databases was supplemented by manual search in the bibliographies of key publications. The methodological quality of the studies included in the review was evaluated independently by two researchers, according to a set of formal criteria. Discrepancies in scoring were resolved through discussion.
RESULTS:
The review yielded seven RCTs, including 101 subjects with ASD (males=95) and 8 males with Fragile X syndrome. The main categories of target symptoms tested in the studies were repetitive behaviors, eye gaze, and emotion recognition. The studies had a medium to high risk of bias. Most studies had small samples (median=15). All the studies but one reported statistically significant between-group differences on at least one outcome variable. Most findings were characterized by medium effect size. Only one study had evidence that the improvement in emotion recognition was maintained after 6 weeks of treatment with intranasal oxytocin. Overall, oxytocin was well tolerated and side effects, when present, were generally rated as mild; however, restlessness, increased irritability, and increased energy occurred more often under oxytocin.
CONCLUSIONS:
RCTs of oxytocin interventions in autism yielded potentially promising findings in measures of emotion recognition and eye gaze, which are impaired early in the course of the ASD condition and might disrupt social skills learning in developing children. There is a need for larger, more methodologically rigorous RCTs in this area. Future studies should be better powered to estimate outcomes with medium to low effect size, and should try to enroll female participants, who were rarely considered in previous studies. Risk of bias should be minimized. Human long-term administration studies are necessary before clinical recommendations can be made
Preoccupation and distress are relevant dimensions in delusional beliefs
No full textBackground and Purpose: A large number of subjective experiences and beliefs with some degree of affinity with psychotic symptoms can be found in the general population. However, the appraisal of these psychotic-like experiences in terms of associated distress, raised preoccupation, and the conviction with which the experience is held can be more discriminative in distinguishing people in need for care from those who simply hold unusual or uncommon beliefs because of cultural reasons. Method: In this study, 81 patients with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, diagnosis of schizophrenia or an affective disorder with psychotic features were compared on the Peters et al Delusions Inventory (PDI) to 210 people from the same local area, who had never received a formal diagnosis of a mental disorder. Results: Patients scored higher than controls on the PDI total score and on its distress, preoccupation, and conviction subscales. A stepwise logistic regression model showed PDI-preoccupation (odds ratio, 2.46; 95% confidence interval, 1.52-3.98) and, marginally, PDI-distress (odds ratio = 1.58; 95% confidence interval, 0.93-2.58) adding discriminative power to PDI total score in distinguishing patients from controls. Conclusions: The evaluation of the severity of delusion-like experiences and beliefs is important in discriminating patients diagnosed with psychosis from people who are not in need of care
Latent class analysis of delusion-proneness: exploring the latent structure of the Peters et al. delusions inventory
No full textLatent class analysis (LCA) has emerged as the best suitable statistical tool to identify separate dimensions (latent classes) when analyzing dichotomous data; its objective is to categorize people into classes using the observed items and to identify those items that best distinguish between classes. LCA was applied to the Peters et al. delusions inventory, an inventory in a dichotomous format (Yes/No) aimed at investigating proneness to delusion in the general population. The study involved 82 patients diagnosed with a psychotic disorder and 210 well-matched healthy controls from the community. Four classes were identified in the sample: a normative one, and 3 classes traceable to the 3 major dimensions of psychosis, i.e., paranoia, grandiosity/hypomania, and the schizophrenia-like profile. The coherent multidimensional structure of the model emerging from LCA of Peters et al. delusions inventory suggests that single clusters of symptoms may be indicative of specific diagnostic categories within the spectrum of psychoses, allowing a more subtle determination of their boundaries and correlates

No full textGoing 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
