Entrepreneurship and psychological disorders in academic publishing

The role that different psychological disorders play in entrepreneurial intentions and behaviors is of increasing interest and importance to the scientific community. Scholars have undertaken a range of investigations that demonstrate that individuals with specific psychological disorders should be treated differently to other individuals. Some studies contribute to psychological disorders shifting from a disability paradigm to a paradigm of diversity. The main objective of this work is to carry out a preliminary analysis of the literature published about the relationship between psychological disorders and entrepreneurship. For this purpose, a bibliometric methodology and a fractional counting method of clustering were developed, identifying and analyzing 108 documents as recorded in the Web of Science and Scopus databases on the relationship between entrepreneurship and psychological disorders. This paper represents a contribution to the state-of-the-art of research on entrepreneurship and psychological disorders, identifying trends and proposing future topics and research lines

Updating known distribution models for forecasting climate change impact on endangered species

To plan endangered species conservation and to design adequate management programmes, it is necessary to predict their distributional response to climate change, especially under the current situation of rapid change. However, these predictions are customarily done by relating de novo the distribution of the species with climatic conditions with no regard of previously available knowledge about the factors affecting the species distribution. We propose to take advantage of known species distribution models, but proceeding to update them with the variables yielded by climatic models before projecting them to the future. To exemplify our proposal, the availability of suitable habitat across Spain for the endangered Bonelli’s Eagle (Aquila fasciata) was modelled by updating a pre-existing model based on current climate and topography to a combination of different general circulation models and Special Report on Emissions Scenarios. Our results suggested that the main threat for this endangered species would not be climate change, since all forecasting models show that its distribution will be maintained and increased in mainland Spain for all the XXI century. We remark on the importance of linking conservation biology with distribution modelling by updating existing models, frequently available for endangered species, considering all the known factors conditioning the species’ distribution, instead of building new models that are based on climate change variables only.Ministerio de Ciencia e Innovación and FEDER (project CGL2009-11316/BOS

Automatic calibration of the SHETRAN hydrological modelling system using MSCE

Automatic calibration is preferred because it provides an objective and extensive searching in the feasible parameter space. In this study, the Modified Shuffled Complex Evolution (MSCE) optimization algorithm is applied to automatically calibrate the physically-based spatially-distributed hydrological model SHETRAN in the 705-km2 semi-arid Cobres basin in southern Portugal, with a spatial resolution of 2 km and a temporal resolution of 1 h. Twenty-two parameters are calibrated for the main types of land-use and soil. Nash-Sutcliffe Efficiency (NSE) is 0.86 for calibration and 0.74 for validation for basin outlet; NSE is respectively 0.65 and 0.82 for calibration, 0.69 and 0.63 for validation of internal gauging stations Albernoa and Entradas. As for storm events, NSE is 0.87 and 0.64 respectively for Storms No.1 (during the calibration period) and No.4 (during the validation period) at basin outlet; it is 0.69 and 0.65 for Storm No.4 respectively at Albernoa andEntradas. The results are satisfactory not only for basin outlet but also for internal gauging stations

Evaluación del estado de la población de cabra montés de los montes de Toledo: relaciones con el ciervo

Iberian wild goat subsp. <i>Capra pyrenaica</i> victoriae inhabits fewer and smaller areas than subs. C. p. hispanica reason why the former is considered as Vulnerable by IUCN. Therefore studies aimed to assess the status of C. p. victoriae are very valuables. We studied the habitat use, parasite excretion rates and diet quality of the Montes de Toledo’s C. p. victoriae population. The red deer is a potential competitor of the Iberian wild goat and subsequently was included in this study. Our results showed that both species had a good population status (good corporal condition, high quality diet and suitable population density). According to the indicators considered in this study we do not expect that red deer suppose a relevant risk for the viability of the Iberian wild goat population. The implications of the results to Iberian wild goat management are deeper discussed.<br><br>La <i>Capra pyrenaica</i> victoriae presenta pocas poblaciones y éstas ocupan áreas reducidas, siendo considerada por ello por la IUCN como vulnerable. Son necesarios, por tanto, estudios locales encaminados a evaluar el estado de dichas poblaciones. En este trabajo estudiamos la población presente en los Montes de Toledo a través del análisis del uso que hace del hábitat, del nivel de parasitación y de la calidad de su dieta. El ciervo fue también incluido en este esquema de monitorización por ser un potencial competidor para la cabra montés. Los resultados indican que ambas especies presentan un adecuado estado poblacional (buena condición corporal, dieta de elevada calidad y valores de densidad razonables). Según los indicadores considerados no sería esperable que el ciervo supusiera un riesgo relevante para la viabilidad de la población de cabra montés. Se discuten las implicaciones de los resultados para la gestión cinegética de la cabra montés

Impact of family structure on long-term survivors of osteosarcoma

Goals of work: Long-term outcomes of osteosarcoma have dramatically improved with the use of modern combination therapies. Such aggressive treatments, however, entail chronic complications. In the present study, we assessed the functional, psychological, and familial status of long-term survivors of osteosarcoma treated at our institution. Materials and methods: Fifteen long-term survivors of osteosarcoma were evaluated for functional and psychological sequelae. Functional assessment was based on a method described by Enneking et al. Psychological assessment was based on General Health Questionnaire 28, Inventory Scale for Traumatic Neurosis, and Family System Test. Main results: Ten patients showed mild functional impairments; only five patients were handicapped more seriously. Depressive symptoms were diagnosed in four patients. A total of six patients revealed unbalanced family structures, including three of the four patients with depressive symptoms, all four patients with symptoms of posttraumatic stress disorder, and five of seven patients who showed poor emotional acceptance. Conclusions: Osteosarcoma survivors will generally recover good functional performance. Only a minority of them remain seriously impaired. One third of the patients present depressive symptoms and posttraumatic stress disorder. Poor coping is closely associated with unbalanced family structures. Therefore, the psychological and familial situation of patients with newly diagnosed osteosarcoma should be carefully assesse

A Mathematica Notebook for Computing the Homology of Iterated Products of Groups

Let G be a group which admits the structure of an iterated product of central extensions and semidirect products of abelian groups G i (both finite and infinite). We describe a Mathematica 4.0 notebook for computing the homology of G, in terms of some homological models for the factor groups G i and the products involved. Computational results provided by our program have allowed the simplification of some of the formulae involved in the calculation of H n (G). Consequently the efficiency of the method has been improved as well. We include some executions and examples
