Significance of perfectionism in understanding different forms of insomnia
Toti?-PoznanoviSanja,?aula-Marojevi? Biljana,Zebi? Mirjana
Srpski Arhiv za Celokupno Lekarstvo , 2012, DOI: 10.2298/sarh1204204t
Abstract: Introduction. Studies consistently show a connection between perfectionism as a multidimensional construct with various psychological and psychopathological states and characteristics. However, studies that analyze the connection between this concept and sleep disturbances, especially modalities of insomnia, are rare. Objective. The aim of this study was to examine whether dimensions of perfectionism can explain different forms of insomnia; difficulties initiating sleep (insomnia early), difficulties during the sleep (insomnia middle), waking in early hours of the morning (insomnia late) and dissatisfaction with sleep quality (subjective insomnia). Methods. The sample consisted of 254 students of the School of Medicine in Belgrade. Predictive significance of nine perfectionism dimensions, measured by Frost’s and Hewitt’s and Flett’s scales of multi-dimensional perfectionism, related to four modalities of insomnia, measured by a structured questionnaire, was analyzed by multiple linear regression method. Results. Perfectionism dimensions are significant predictors of each of the tested forms of insomnia. Doubt about actions significantly predicts initial insomnia; to other-oriented perfectionism in the negative pole and socially prescribed perfectionism underlie the difficulties during the sleep, while organization and parental criticism underlie late insomnia. Significant predictors of subjective insomnia are personal standards and organization and to other-oriented perfectionism on the negative pole. Three of nine analyzed dimensions were not confirmed as significant; concern over mistakes, parental expectations and self-oriented perfectionism. Conclusion. Various aspects of perfectionism can be considered as a vulnerability factor for understanding some forms of insomnia. Out of all forms of insomnia tested, perfectionism as the personality trait proved to be the most significant for understanding subjective insomnia.

Abstract: Neuropsychological deficits associated with unipolar depression are seen in a broad range of cognitive domains. Executive deficits may be prominent in depression. Investigation of executive functions in younger adult patients with unipolar depression has been the focus of our study. Twenty-two consecutively depressive inpatients (24-36 years) and 21 healthy control subjects, matched on age, gender, education and verbal IQ were included in the study. Neuropsychological tests for executive functions were applied to all subjects. Unipolar young depressives showed significantly reduced number of completed categories and more trials for completion of the first category on Wisconsin Card Sorting Test (WCST). No difference of tasks assessing the short-term memory, total errors on WCST, perseverative and non-perseverative errors, and of both phonemic and semantic conditions of verbal fluency was found between groups. The results suggested that unipolar depressives had specific cognitive style characterized by "negative cognitive set" (stronger negative reaction to negative feedback) and by failure to use negative feedback to improve their performance.
Neuropsychological profile of patients with bipolar depression in remission

Vojnosanitetski Pregled , 2005, DOI: 10.2298/vsp0508543t
Abstract: Aim. To determine if the patients with bipolar affective disorder, after the depressive phase, would exhibit cognitive impairment in remission. Methods. Twenty three euthymic patients with bipolar disorder were matched, on a case-by-case basis, to twenty-one healthy subjects in the control group, for the presence of the symptoms of depression. The patients and the control group were tested with a battery of neuropsychological tests. Results. Impairments were found in the patients compared with the control group in tests of verbal learning and memory and in tests of executive function. Verbal learning and memory, as well as executive functions, did not correlate either with the clinical indices of patients, or with the demographic and baseline clinical measures of depression. Conclusion. Impaired verbal learning and memory and executive functions may represent a trait rather than the state variables in bipolar disorder.
Social cognition in schizophrenia

Srpski Arhiv za Celokupno Lekarstvo , 2011, DOI: 10.2298/sarh1112828t
Abstract: Patients with schizophrenia display alterations in social cognition, as well as in the realm of neurocognition. It is still unclear to what extent these two cognitive domains represent two separate dimensions or different expressions of a unified deficit. Tasks used to assess social cognition subcomponents cover basic social cognition, such as mentalisation, data collection and making conclusions, source monitoring and characteristics of life-styles. The variety of findings of various studies is probably related to the fact that most studies considered social cognition as one-dimensional construct represented, for example, by unique measurements of emotional recognition. Research results dealing with social cognition suggest that the impairment of social cognition is the characteristic feature of schizophrenia and have important implications for the development, course and outcome of this disorder.

Landslide Susceptibility Assessment Using Conditional Analysis and Rare Events Logistics Regression: A Case-Study in the Antrodoco Area (Rieti, Italy)  [PDF]
Vittorio Chiessi, Simona Toti, Valerio Vitale
Journal of Geoscience and Environment Protection (GEP) , 2016, DOI: 10.4236/gep.2016.412001
Abstract: This paper discusses some methodological aspects for the production of susceptibility maps of slope instability developed within the CARG Project (Geological Cartography of Italy at 1:50,000 scale). It describes an example of a susceptibility map in the presence of low susceptibility, using database having zero or negligible cost, with the aim to test some methodologies that can be easily reproducible to get a first estimate of the landslide susceptibility on a wide area. Two statistical approaches have been applied: the non-parametric conditional analysis and the logistic analysis for rare events. The predictive ability obtained from the two methodologies, was evaluated by the success-prediction curves for the conditional analysis, and by the Receiver Operating Characteristic curve (ROC), for the logistic model. The landslide susceptibility maps have been classified into four classes using both the Natural Breaks algorithm and the method proposed by Chung and Fabbri (2003). The paper considers the influence of these two classification methods on the quality of final results.

Frattura ed Integrità Strutturale , 2009,
Abstract: Il presente articolo riguarda la modellazione del comportamento meccanico di elementi in muratura intesi come sistemi eterogenei composti da malta, blocchi ed interfacce di connessione. La strategiacomputazionale che viene adottata consiste nel modellare separatamente i blocchi, i letti di malta ed le interfacce responsabili di fenomeni di decoesione malta-blocco; a tale scopo, si propone uno speciale modello di interfaccia che combina il danneggiamento con l’attrito. Si sviluppa una procedura numerica, basata sull’algoritmo backward di Eulero, per risolvere il problema evolutivo; per il passo temporale si utilizza invece la tecnica predictor-corrector a controllo di spostamenti. Si effettuano alcune applicazioni numeriche con lo scopodi verificare la capacità del modello e dell’algoritmo proposto nel riprodurre la risposta non lineare della muratura dovuta a fenomeni di degrado localizzati. Infine, si conduce lo studio della modellazione di un arco murario, confrontando i risultati numerici con quelli sperimentali; si dimostra la abilità del modello proposto nel simulare il comportamento globale della struttura ad arco in termini di carico ultimo e di meccanismo di collasso.
Elements for an approach to the Physics in high school and the daily of the student′s job

Investiga??es em Ensino de Ciências , 2011,
Abstract: From situations experienced by students is a plausible methodological strategy with a view to learning more meaningful. In this paper we argue for a physics of everyday life in perspective supported student worker, mostly in secondary education in Brazil. Our goal was to locate and analyze elements of knowledge of physics present in the work activities of students. The analysis of these elements, from a focus of the Historical-Cultural Psychology, provides guidelines for educational work in Physics Education, aiming to better use the potential of working students in developing conceptual levels more complex, not yet attained by these students. These levels of development are achieved, according to the approach of Historical-Cultural Psychology, in that there is a convergence of everyday beliefs and scientific concepts in the teaching and learning. We concluded that three conditions are necessary for the relationship between Vygotskian scientific knowledge and daily life can be realized in the context of Physical Education for working students.
