On the theorem of hartogs in non-Archimedean valued fields

AbstractLet U = U0 × U1 × … × Un be an open polyring in a non-Archimedean valued, locally non-compact field. Let the function f be defined in the polyring U and satisfy the following conditions: (1) f is holomorphic for every x ∈ U0 separately in each of the rest variables yi ∈ Ui, i = 1, 2,…,n; (2) f is holomorphic in x ∈ U0 for every (y1,…,yn) ∈ V1 × … × Vn, where Vi is a certain disk from the ring Ui. Then, if the valuation is dense, the function f is holomorphic in the polyring U. If the valuation is discrete, then the function f is holomorphic in a domain close to the polyring U

Assessing the Need for a Specialist Service for People with Intellectual Disabilities and Mental Health Problems Living in Israel: A Qualitative Study

Background: It is well established that people with intellectual disabilities are at higher risk of developing mental illnesses. This study aimed to assess the need for a specialized service for people (children and adults) with intellectual disabilities and mental health problems living in Israel. Methods: Our research question was: is there a need for a specialist mental health service for people with intellectual disabilities living in Israel and, if so, what type of service would be most appropriate? We conducted a qualitative study using semi-structured interviews with 14 major stakeholders to identify key themes in response to our research question. The data were coded and themes were identified. Results: Participants were generally not satisfied with current mental health care for people with intellectual disabilities and there was a general agreement that services are in need of improvement. We identified three major themes from the data. These were: current services, future services, and ways to facilitate change. Conclusion: We hope that our findings will be instrumental in shaping the ongoing debate about the best form of delivery of services to this population in Israel. Specifically, we suggest the development of a more specialized system, with the formation of multidisciplinary regional assessment and treatment units in parallel with improved relevant training for all mental health workers and the possibility of referral to specialized teams in more complex cases

A program that "cannot conform to all". Economics and bureaucracy in the final years of the first peronist.

El presente artículo indaga en algunos aspectos de la política económica del gobierno peronista en el periodo que se abre a partir de 1953-1954, al momento de consolidación de los cambios introducidos a las políticas económicas iniciales luego de la crisis de 1949-1952. Específicamente se estudia un programa poco considerado por la historiografía, el Plan de Acción de Equilibrio para la Economía Nacional anunciado en octubre de 1954 y las transformaciones burocráticas que lo acompañaron. De esta forma, nuestro objetivo es anudar el análisis de las modificaciones operadas en los ámbitos de gestión económica con las medidas tomadas en materia de política económica e identificar las capacidades estatales e instrumentos diseñados por el peronismo.This article explores some aspects of the Peronist government’s economic policy in the period from 1953 to 1954 at the time of consolidation of the changes made to the initial economic policy after the crisis of 1949-1952. Specifically we study a program scarcely considered by the historians, the Action Plan for National Economic Balance of October 1954, and bureaucratic changes that accompanied it. Thus, our goal is to tie the analysis of the amendments made in the areas of economic management with the measures taken in regard to economic policy, with the specific purpose of identifying the links between the two areas and arrive at a more complete understanding of actions and determinants of these changes.Fil: Rougier, Marcelo Norberto.

A shift in the thermoregulatory curve as a result of selection for high activity-related aerobic metabolism

According to the “aerobic capacity model,” endothermy in birds and mammals evolved as a result of natural selection favoring increased persistent locomotor activity, fuelled by aerobic metabolism. However, this also increased energy expenditure even during rest, with the lowest metabolic rates occurring in the thermoneutral zone (TNZ) and increasing at ambient temperatures (Ta) below and above this range, depicted by the thermoregulatory curve. In our experimental evolution system, four lines of bank voles (Myodes glareolus) have been selected for high swim-induced aerobic metabolism and four unselected lines have been maintained as a control. In addition to a 50% higher rate of oxygen consumption during swimming, the selected lines have also evolved a 7.3% higher mass-adjusted basal metabolic rate. Therefore, we asked whether voles from selected lines would also display a shift in the thermoregulatory curve and an increased body temperature (Tb) during exposure to high Ta. To test these hypotheses we measured the RMR and Tb of selected and control voles at Ta from 10 to 34°C. As expected, RMR within and around the TNZ was higher in selected lines. Further, the Tb of selected lines within the TNZ was greater than the Tb of control lines, particularly at the maximum measured Ta of 34°C, suggesting that selected voles are more prone to hyperthermia. Interestingly, our results revealed that while the slope of the thermoregulatory curve below the lower critical temperature (LCT) is significantly lower in the selected lines, the LCT (26.1°C) does not differ. Importantly, selected voles also evolved a higher maximum thermogenesis, but thermal conductance did not increase. As a consequence, the minimum tolerated temperature, calculated from an extrapolation of the thermoregulatory curve, is 8.4°C lower in selected (−28.6°C) than in control lines (−20.2°C). Thus, selection for high aerobic exercise performance, even though operating under thermally neutral conditions, has resulted in the evolution of increased cold tolerance, which, under natural conditions, could allow voles to inhabit colder environments. Further, the results of the current experiment support the assumptions of the aerobic capacity model of the evolution of endothermy

More functions of torpor and their roles in a changing world

Increased winter survival by reducing energy expenditure in adult animals is often viewed as the primary function of torpor. However, torpor has many other functions that ultimately increase the survival of heterothermic mammals and birds. In this review, we summarize new findings revealing that animals use torpor to cope with the conditions during and after natural disasters, including fires, storms, and heat waves. Furthermore, we suggest that torpor, which also prolongs longevity and was likely crucial for survival of mammals during the time of the dinosaur extinctions, will be advantageous in a changing world. Climate change is assumed to lead to an increase in the occurrence and intensity of climatic disasters, such as those listed above and also abnormal floods, droughts, and extreme temperatures. The opportunistic use of torpor, found in many heterothermic species, will likely enhance survival of these challenges, because these species can reduce energy and foraging requirements. However, many strictly seasonal hibernators will likely face the negative consequences of the predicted increase in temperature, such as range contraction. Overall, available data suggest that opportunistic heterotherms with their flexible energy requirements have an adaptive advantage over homeotherms in response to unpredictable conditions

Czy psychiatria jest nauką humanistyczną? : problem rozumienia środowiska zewnętrznego w psychiatrii

One of the most frequent problem taken in the philosophy of psychiatry is the question about the role of neurobiological and environmental factors (natural and socio-cultural) in the development of mental disorders. Investigating the influence of this second group of factors requires psychiatry to adopt a cultural, social or philosophical point of view, and create an interdisciplinary perspective. However, each of the individual disciplines, uses a different language, concepts and paradigms. It may be an obstacle in a consistent description of the phenomenon of mental illness. According to the hypothesis, the concept that can help develop a unified approach to this problem is the processual landscape, the concept of embodied and embedded cognition and James Gibson's idea of affordances. First I shall introduce the problem of the scientific validity of psychiatry, then I am going to discuss the conception of environment based on the theory of processual landscape, James Gibson’s affordances and a proposal to distinguish between space and place. Finally, I shall consider the possibility of applying this understanding of the environment within interdisciplinary psychiatry
