analysis of power in the network society
اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولDynamic windowing reveals task-modulation of functional connectivity in schizophrenia patients vs healthy controls
Introduction Studying functional connectivity (correlations among voxels) among brain networks helps reveal important information about brain function in healthy and diseased brain. Being a major psychotic disorder, schizophrenia, is known to disrupt cognitive and motor functions and it has been shown to disrupt task-related functional networks during performance of certain tasks. Functional ne...
متن کاملFunctional network connectivity with temporal derivatives of sICA time-courses in schizophrenia patients vs healthy controls
Introduction There has been a growing interest in analyzing functional connectivity among brain networks. Functional network connectivity (FNC) can be assessed by measuring correlations between time-courses of different brain networks, which, for example, can be estimated with spatial independent component analysis (sICA). Spatially independent components (ICs), or brain networks, have associat...
متن کاملBrain network connectivity in individuals with schizophrenia and their siblings.
BACKGROUND Research on brain activity in schizophrenia has shown that changes in the function of any single region cannot explain the range of cognitive and affective impairments in this illness. Rather, neural circuits that support sensory, cognitive, and emotional processes are now being investigated as substrates for cognitive and affective impairments in schizophrenia, a shift in focus cons...
متن کاملReal-time neural activity and connectivity in healthy individuals and schizophrenia patients.
Processing of facial information is distributed across several brain regions, as has been shown recently in many neuroimaging studies. Disturbances in accurate face processing have been repeatedly demonstrated in different stages of schizophrenia. Recently, electroencephalography (EEG) and tomographic analysis of average magnetoencephalographic (MEG) data were used to define the latencies of si...
