Vliv memantinu a riluzolu na učení ve zvířecím modelu obsedantně-kompulzivní poruchy vyvolaném sensitizací pomocí 8-OH-DPAT / Effects of memantine and riluzole on learning deficits in an animal model of obsessive-compulsive disorder induced by 8-OH-DPAT sensitizationMainerová, Karolína January 2020 (has links)
Obsessive-compulsive disorder is a chronic psychiatric disease. It seriously limits the quality of life of patients. Treatment of OCD is not yet fully successful and still many patients are left with debilitating symptoms without functioning medication. Animal models of genetic, behavioral, pharmacological, and optogenetic origins are beneficial in the achievement of new understandings of the disease. Chronic sensitization of serotonin 1A and 7-receptors with an agonist 8-OH-DPAT ((8- hydroxy-2-(di-propylamino)-tetralin hydrobromide) induces perseverative and compulsive behaviors, which is considered to constitute an animal model of OCD. In this thesis, the 8-OH- DPAT model has been tested in the active place avoidance task on Carousel maze to provide information about the model on learning. Second, this model is used to determine, whether co- administration of memantine or riluzole alleviates the cognitive and learning deficits of this model. To uncover these effects, an active place avoidance task on a Carousel maze was used. Measured criteria were total distance, entrances to the shock sector, total number of shocks, and median speed after the shock. During habituation, the animals were sensitized to 8-OH-DPAT (with a control group that did not receive 8-OH-DPAT but only saline). In an...

Fine-Grained Analyses of Early Autism-related Social Behavior in Real-World Scenarios by Machine LearningAlvari, Gianpaolo 23 February 2022 (has links)
Autism Spectrum Disorder (ASD) is a condition that carries high costs for families and the healthcare system, requiring extensive management both in terms of diagnosis and treatment. The implementation of AI-based systems in clinical practice represents a possible supportive solution that can help clinicians by providing more systematic meth- ods to monitor child behavior. The main advantage over more traditional observational approaches is to offer quantitative and refined analysis solutions that can be ecological at the same time. The relevance of AI in clinical applications can have a role both in the challenge of early detection and in designing intervention programs better tai- lored to the specific functioning of children with ASD. The research project presented in this dissertation focused on developing AI-based systems for fine-grained analysis of autism-related social behaviors and their validation in concrete clinical environments. Specifically, in Chapter 2, our first study is presented, which targets on implementing a computational phenotyping system to address the need for new early markers of the condition. Through fine-grained analytics of facial dynamics in videos, we identified a set of features that distinguished young (6-12 months) infants with ASD (18 ASD, 15 non-ASD) during unconstrained at-home interactions. In Chapters 3 and 4, we introduce EYE-C, a Behavior Imaging model for robust analysis of eye contact episodes in eco- logical therapist-child interactions. The system was validated in the clinical setting for personalized early intervention. First, we investigated the influence of extracted features in categorizing spectrum heterogeneity across a sample of 62 preschool (<6 years) chil- dren with ASD. Further, we tested our metrics as predictors of early intensive treatment outcomes in a sub-sample of 18 subjects with ASD. The project aims to demonstrate the feasibility of effective computational systems that are robust to the high variability of unstructured interactions, with emphasis on the applicative value in real-world scenar- ios. Even though based on limited sample sizes, the work presented may offer interesting insights into the perspective of integrating AI into clinical practice.
The research project was funded by an FBK scholarship and developed in a double in- ternship at ODFLab (University of Trento) and the FBK Data Science for Health (DSH) research unit.

Toward a Better Understanding of the Roles of Social Exchanges and Psychological Safety on Followers' Change-Oriented BehaviorsHalliday, Cynthia Saldanha 18 March 2019 (has links)
Organizational change and innovation are critical for business survival and more likely to occur when employees engage in change-oriented behaviors. Previous studies have examined the direct effects of workplace social exchanges on employees’ change-oriented behaviors; however, less attention has been given to the combined effects of these exchanges and the mechanisms by which these relationships occur. In this study, I look at the combined effects of leader-member exchange, trust in team members, and perceived organizational support on voice, innovative, and learning behaviors via psychological safety. In addition, based on the understanding that psychological safety is not always present in the work environment, I look at the conditions under which these workplace social exchanges lead to the aforementioned behaviors even when psychological safety is low or absent. Therefore, the purpose of this dissertation is three-fold: (1) to explore the combined effects of leader-member exchange, trust in team members, and perceived organizational support in improving followers’ psychological safety within the organization, (2) to investigate the mediating role of psychological safety on the relationships between workplace social exchanges and followers’ change-oriented behaviors, and (3) to expand on previous findings and examine the conditions under which these social exchanges and psychological safety lead to followers’ change-oriented behaviors. Specifically, I propose and test a theoretical model derived from social exchange theory to examine conditional indirect effects of leader-member exchange, trust in team members, and perceived organizational support on voice, innovative, and learning behaviors through psychological safety within the organization, and to examine the role of proactive personality, political skill, perceived team social integration, perceived support for innovation and perceived organizational justice as second stage moderating variables that may compensate for low psychological safety within the organization. My theoretical model was tested using lagged data collected from leader-follower dyads representing 174 followers and 85 leaders from four organizations located in the United States. To test this theoretical model, I used a quantitative non-experimental research design, a survey method, and multilevel analytical procedures.

Il Multinational Managerial Community Index per analizzare l’internazionalizzazione d’impresa da una prospettiva incentrata sul comportamento collaborativo internazionale dei manager relativamente alla propria catena del valore / IL MULTINATIONAL MANAGERIAL COMMUNITY INDEX PER ANALIZZARE L'INTERNAZIONALIZZAZIONE D'IMPRESA DA UNA PROSPETTIVA INCENTRATA SUL COMPORTAMENTO COLLABORATIVO INTERNAZIONALE DEI MANAGER RELATIVAMENTE ALLA PROPRIA CATENA DEL VALORE / The Multinational Managerial Community Index to analyze the firm’s internationalization degree from a perspective focused on the international collaborative managerial behavior relative to its value chain.ALBERTIN, ROBERTO 24 May 2017 (has links)
La presente tesi teorica propone il MOPC index per misurare quanto i manager abbiano generato una comunità multinazionale di gestione aperta di un generico processo considerando congiuntamente l’affiliazione, la connettività interna, la forza e la multinazionalità. A tal fine ho impiegato il SAOM-Behavior valutando la collaborazione internazionale di processo ed annessa propensione come variabili multiple i cui valori e co-evoluzione dipendono dalla co-influenza tra le collaborazioni internazionali fasiche, tra le medesime e le rispettive propensioni fasiche e tra queste ultime. L’intensità relazionale dipende dal modello mentale condiviso, generatosi a livello di team internazionale, su una certa fase del processo mentre la propensione è funzione dell’orientamento e dell’attitudine alla collaborazione internazionale fasica. Il MOPC index è stato applicato alla comunità multinazionale di innovazione aperta e di gestione aperta introducendo due indici teorici: MOIC index e MOMC index. Infine ho teorizzato la catena del valore del manager (MVC) impiegando il processo innovativo e gestionale; considerando le collaborazioni internazionali sui due processi con annesse propensioni, si ho analizzato la collaborazione internazionale sulla MVC, la relativa propensione e la loro co-evoluzione. Cosi facendo, ho introdotto il MMC index per misurare la comunità multinazionale manageriale e, mediante questo, la multinazionalizzazione d’impresa da una prospettiva relazionale manageriale. / This thesis presents the theoretical MOPC index to measure how much the managers generate a multinational open process community by considering the affiliation, the internal connectivity, the strenghtness and the multinationality. I employed the SAOM-Behavior by evaluating the international process collaboration and the respective propensity as multiple variables whose value and co-evolution depend on the co-influence between the international collaborations phasic, between the same and the respective propensities phasic and between them. The intensity of these relationships depends on the International phasic team mental model sharing (TMMS) while the propensity’s one depends on the orientation and the attitude. Then the MOPC index has been applied to measure the multinational open innovation community and the multinational open management community by introducing the MOIC index and the MOMC index. Finally, I introduced the managerial value chain (MVC) as composed of the innovative and the management process. By integrating the international collaborations related to the two processes and their propensities It’s possible to measure the international MVC collaboration, the correlated propensity and their co-evolution. In doing so, I introduced the MMC index to determine the multinational managerial community’s degree and use it to evaluate the firm’s multinationalization by a managerial relational perspective.
