All of our information about the world is derived from the function of our senses, and thus they are the principal source of all our knowledge. This was recognized explicitly by early Greek philosophers, remained an important point of discussion for nineteenth‐century philosophers, and continues to be a key issue for present‐day philosophers, psychologists, and neuroscientists. It is a key issue in cognitive science because, by initiating the processes that store and evaluate information, sensory information transmission can be considered a (...) cognitive initiator. In a very real sense, who we are and how we see the world are the result of the experiences that are mediated by our sensory systems. These are some of the reasons why the study of sensory systems has occupied such a prominent place in modern cognitive neuroscience. (shrink)

How well is the field of political studies doing and where is it headed? Such questions are examined and answered in this broad world overview of political science, along with the advances and shortcomings, as well as the recommended prescriptions for the future decades of the new century. The book includes three world regional assessments of the discipline, along with an in-depth survey of various sub-disciplinary fields and a concluding critical essay on the future of political studies. This is the (...) final volume in a book series on the development of political science, created in 2000 by Research Committee 33 of the International Political Science Association (IPSA) on the study of political science as a discipline. Contents include: Political Science in Three Asian Democracies: Disaffected (Japan), Third-Wave (Korea), and Fledgling (China) * Political Science in Europe: Its Development as a Discipline * Political Science in North America and Other Continents: Is There a Genuinely Int.

Background: There are few standardized measures available to assess executive function in a naturalistic setting for children. The Children’s Cooking Task is a complex test that has been specifically developed to assess EF in a standardized open-ended environment. The aim of the present study was to evaluate the internal consistency, inter-rater reliability, sensitivity and specificity, and also convergent and divergent validity of the Norwegian version of CCT among children with pediatric Acquired Brain Injury and healthy controls.Methods: The present study has (...) a cross-sectional design, based on baseline data derived from a multicenter RCT. Seventy-five children with pABI from two university hospitals with parent-reported executive dysfunction and minimum of 12 months since injury/completed cancer therapy, as well as 59 HCs aged 10–17 years, were assessed with CCT using total errors as the main outcome measure. The pABI group completed tests assessing EF on the impairment level within the ICF framework, and on the participation level. In addition, they completed tests of intellectual ability, processing speed, attention, learning, and memory. Finally, overall functional outcome was evaluated for the children with pABI.Results: Acceptable internal consistency and good inter-rater reliability were found for the CCT. Children with pABI performed significantly worse on the CCT than the HCs. The CCT identified group membership, but the sensitivity and specificity were overall classified as poor. Convergent validity was demonstrated by associations between the CCT and performance-based tests assessing inhibition, cognitive flexibility, and working memory, as well as teacher-reported executive dysfunction. Divergent validity was supported by the lack of association with performance-based measures of learning and memory, attention, and verbal intellectual ability. However, there was a moderate association between the CCT and performance-based tests of processing speed. Lastly, better performance on the CCT was associated with a better functional outcome.Conclusion: Our study with a relatively large sample of children with pABI and HC’s demonstrated good psychometric properties of the CCT. CCT performance was associated with the overall level of disability and function, suggesting that CCT is related to the level of activity in everyday life and participation in society. Hence, our study suggests that the CCT has the potential to advance the assessment of EF by providing a valid analysis of real-world performance. Nevertheless, further research is needed on larger samples, focusing on predictors of task performance, and evaluating the ability of CCT to detect improvement in EF over time. The patterns of error and problem-solving strategies evaluated by the CCT could be used to inform neuropsychological rehabilitation treatmentand represent a more valid outcome measure of rehabilitation interventions.

To controlforceaccurately under a wide range of behavioral conditions, the central nervous system would either require a detailed, continuously updated representation of the state of each muscle (and the load against which each is acting) or else force feedback with sufficient gain to cope with variations in the properties of the muscles and loads. The evidence for force feedback with adequate gain or for an appropriate central representation is not sufficient to conclude that force is the major controlled variable in (...) normal limb movements.Morton's hypothesis, thatlengthis controlled by a follow-up servo, has a number of difficulties related to the delays, gains, variability, and specificity in feedback pathways comprising potential servo loops. However, experimental evidence is consistent with these pathways providing servo assistance for some movements produced by coactivation of α- and static γ-motoneurons. Dynamic γ-motoneurons may provide an additional input for adaptive control of different types of movements.The idea that feedback is used to compensate for changes in musclestiffnesshas received experimental support under static postural conditions. However, reflexes tend to increase rather than decrease the range of variation in muscle stiffness during some cyclic movements. Theoretical problems associated with the regulation of stiffness are also discussed. The possibilities of separate control systems forvelocityorviscosityare considered, but the evidence is either negative or lacking. I conclude that different physical variables can be controlled depending on the type of limb movement required. The concept of stiffness regulation is also useful under some conditions, but should probably be extended to the regulation of the visco-elastic properties (i.e., the mechanical impedance) of a muscle or joint.

Jewish spirituality and religion include dynamics that are different from other traditions and have important implications for relational forms of spirituality. Certain approaches to relational Judaism (e.g. Mussar) have offered insights for understanding the folk psychology of relational spirituality in Jewish contexts but have not generated empirical research. Existing research in the psychology of Jewish religion and spirituality draws on several theoretical frameworks and has generated helpful findings. In this synthetic review, we foreground the role of theory in psychological research (...) and offer a brief review of several theoretical frameworks used in research on the psychology of Jewish religion and spirituality (cognitive-behavioral, psychodynamic, cultural psychology of religion, and positive psychology). The relational spirituality model (RSM) is summarized as a conceptual framework that could be useful for future research in this area. We use the RSM as a heuristic organizing framework to review several lines of prior empirical research on the psychology of Jewish religion and spirituality that fit within the RSM domains of spiritual dwelling, seeking, and struggles. The final section outlines future directions in research in this area based on the RSM, with particular attention to dimensions of diversity (e.g. gender, sexual orientation), diverse contexts of Jewish spirituality, Jewish spirituality in relation to both mental health suffering and flourishing, and historical trauma. We also highlight the need for research on Jewish spiritual development in communal settings (e.g. congregations, seminaries) to provide a deeper understanding at both individual and communal levels, and interdisciplinary integration with Jewish theology.

Indagar sobre la esencia femenina es una tarea fundamental en nuestro tiempo. Sin embargo, es un esfuerzo que ha caído en el descrédito dado que se considera que no tiene en cuenta las diferencias individuales de las mujeres y contribuye a la sumisión femenina. Especialmente, a través de la formación de imágenes estereotipadas. En este artículo estudiaremos las conferencias sobre la mujer de Edith Stein, y algunos de sus estudios antropológicos, con la intención de aproximarnos a una comprensión que (...) une la esencia femenina con la acción y manifiesta su intrínseca unidad con la individualidad. Stein está convencida que toda mujer posee una triple vocación: a nivel humano, femenino e individual que se ha de desarrollar de manera integral y complementaria. Sin embargo, esto solo será posible si reconoce el orden metafísico –cristiano– del que depende su ser. (shrink)

It is customary to consider late Imperial historiography as a barren waste of meagre and inaccurate chronicles and incompetent rhetorical epitomes, all overshadowed by the giant figure of Ammianus Marcellinus, the greatest literary genius, as E. Stein has called him , between Tacitus and Dante. In fact, however, the fifth century A.D. produced at least one writer who was, in the words of Niebuhr, ‘second to no historian even of the best ages in talent, good faith and wisdom; elegant (...) and very pure in style, he justly acquired praise and glory both among contemporaries and succeeding ages’. Niebuhr was referring to Priscus of Panium in Thrace, but Priscus was a member of a school of historical writing which had been founded earlier in the fifth century by Olympiodorus, an historian of scarcely less merit than Priscus and author of what J. B. Bury called ‘a highly important work’. Since even Schmid-Stahlin are not able to refer to a single essay or mono-graph on Olympiodorus, it may not be amiss to assemble the facts which are known about him and to try to discover, so far as the scanty materials permit, what sort of man he was and what sort of work he produced.
