Representing functions/procedures and processes/structures for analysis of effects of failures on functions and operations
Current qualitative device and process models represent only the structure and behavior of physical systems. However, systems in the real world include goal-oriented activities that generally cannot be easily represented using current modeling techniques. An extension of a qualitative modeling system, known as functional modeling, which captures goal-oriented activities explicitly is proposed and how they may be used to support intelligent automation and fault management is shown
Neural Correlates of the Dual-Level Transformational Leadership Model
Introduction/Main Objectives: This study considered neural processes of transformational leadership based on quantitative electroencephalography (qEEG). Background Problems: This research aims at providing biomarkers for effective (i.e., transformational) leadership. Novelty: We considered transformational leadership on a detailed level, namely its individual-focused and group-focused sub-dimensions, to analyze the underlying brain processes. As for the individual-focused sub-dimensions of transformational leadership, we utilized innovation and performance orientation, while for the group-focused sub-dimensions, we choose vision and team spirit. Research Methods: Fifty-two dyads, consisting of (a) student pairs and (b) supervisor-subordinate dyads, participated in a simulated role-play that was intended to be a performance review while the electrical activity of the brain was recorded. Finding/Results: Results show that the group-focused sub-dimensions of transformational leadership could be positively linked to right frontal lobe coherence and negatively linked to left frontal lobe coherence. Results showed no relation between the individual-focused sub-dimensions and frontal lobe coherence. Conclusion: The results allow for a deeper understanding of the neural processes of transformational leadership and its individual-focused and group-focused sub-dimensions, respectively
Three-year follow-up study exploring metacognition and function in individuals with first episode psychosis
Introduction: Research has demonstrated that functional outcome in psychosis is predicted by factors such as neurocognition, functional capacity, symptoms and, more recently, metacognition. Metacognitive ability has been demonstrated to mediate between neurocognition and functional outcome in First Episode Psychosis (FEP). Whether metacognition also predicts longer-term recovery in first episode is unknown. This study assessed whether neurocognition, functional capacity and metacognitive ability in FEP predicted functional outcome three years later.
Methods: Eighty individuals with First Episode Psychosis were re-contacted after an average three years (range: 26-45 month follow-up) from baseline. Twenty-six participants (33%) completed neurocognitive measures, metacognition, functional capacity, functional outcome (hours spent in structured activity per week) and psychopathology at baseline and at follow-up.
Results: Individual regression analyses demonstrated neurocognition, functional capacity and metacognitive ability at baseline significantly predicted functional outcome at three years. However, when baseline functional outcome was controlled, only metacognitive ability was a significant predictor of change in functional outcome from baseline to follow-up, p<.001. This model explained 72% (adjusted r² = .69) of the variance in functional outcome at follow-up. Negative symptoms did not change the model.
Discussion: This study demonstrated that better metacognitive ability significantly predicted improvement in functioning in FEP across a 3-year period. This highlights the potential value of clinical interventions that focus on improving metacognitive ability at first point of illness to maximize recovery
A large European, multicenter, multinational validation study of the Brief Negative Symptom Scale
Negative symptoms represent an unmet need of treatment in schizophrenia. Although a consensus exists on negative symptom construct, and second generation assessment instruments reflecting the consensus are available, studies still rely upon old assessment instruments, that do not reflect recent conceptualizations and might limit progress in the search for effective treatments. This is often the case in the European context, where one of the challenges encountered in designing large studies is the availability of validated instruments in the many languages of the continent. To address this challenge and promote sound research on negative symptoms in Europe, the ECNP Schizophrenia Network coordinated a large multicenter, multinational validation study of the Brief Negative Symptom Scale (BNSS). Clinically-stable subjects with schizophrenia (SCZ, N = 249) were recruited from 10 European Countries. Apart from BNSS, subjects were administered the Positive and Negative Syndrome Scale (PANSS) and standardized instruments for depression, extrapyramidal symptoms and psychosocial functioning. Results showed an excellent internal consistency, convergent and discriminant validity of BNSS and replicated a 5 factor-model. A larger number of subjects with predominant negative symptoms, i.e. the target population for clinical trials, was identified by using the BNSS compared to the PANSS. Regression analysis showed that BNSS-avolition, a key negative symptom poorly assessed by PANSS, explained 23.9% of psychosocial functioning, while no combination of the PANSS core negative symptoms showed the same impact on functioning. The study demonstrated that BNSS has substantial advantages with respect to PANSS for the identification of the avolition domain and subjects with predominant negative symptoms
Asian American RSO's on the University of Illinois Campus: Organization Interaction and Reasons for Joining
This paper looks at Asian American Registered Student Organizations (RSO) on the University of Illinois campus. We wished to understand the particular inter-group dynamic of Asian American RSO's and to understand whether groups were really united under the umbrella term APAC (Asian Pacific American Coalition). If so, what sort of implications, in regards to community and solidarity, were assumed through this involvement. Additionally, we wished to find the reasons individuals joined a specific organization over another within the spectrum of Asian American organizations on campus
