Este artigo tem por objetivo apresentar e discutir a sugestão de Fred Dretske para analisar o problema dos qualia. Tal problema, caro à Filosofia da Mente, ficou conhecido pela discussão desenvolvida por Thomas Nagel em seu clássico artigo What is it like to be a bat. Nesse artigo, Nagel postulou a impossibilidade de se conhecer, em perspectiva de terceira-pessoa, os aspectos da experiência humana. Ele considera que, mesmo após as descrições objetivas da experiência de um sujeito, escapariam ainda aspectos qualitativos, (...) fundamentais para se caracterizar os qualia. A partir de sua Tese Representacionista da mente, Dretske argumenta que seria possível dissolver esse problema se admitirmos que a mente é a face representacional do cérebro, a natureza dos qualia seria, assim, representacional. Nesse contexto, os fatos mentais relacionados às experiências seriam fatos representacionais: se conhecermos a natureza desses fatos representacionais conheceremos também a experiência do sistema que a representa. Diante de tal entendimento, discutimos em que medida a proposta dretskeana constitui uma alternativa ao problema dos qualia. (shrink)

El escenario energético de escasez a nivel mundial se empieza a reflejar fuertemente en América Latina. Chile tiene una política energética diseñada en el período dictatorial, y administrada en la democracia, que hace muy vulnerable su economía, su medio ambiente y su seguridad. En este artículo se analizan críticamente los diversos aspectos que inciden fuertemente en el actual escenario energético chileno, sobre todo en lo que respecta a la política de integración con sus vecinos latinoamericanos, desde donde se puede vislumbrar (...) también una solución sustentable a los problemas energéticos futuros.

RATIONALE AND AIMS: Total hip and knee replacements, usually, have long waiting lists. There are several prioritization tools for these kind of patients. A new tool should undergo a standardized validation process. The aim of the present study was to validate a new prioritization tool for primary hip and knee replacements. METHODS: We carried out a prospective study. Consecutive patients placed on the waiting list were eligible for the study. Patients included were mailed a questionnaire which included, among other questions, (...) the seven items of the priority tool and the Western Ontario and McMasters Universities Arthritis Index (WOMAC) specific questionnaire. The priority tool gives a score from 0 to 100 points, and three categories (urgent, preferent and ordinary). We studied the content and construct validity. We used Student's t-test or one-way analysis of variance. Correlational analysis was used to evaluate convergent and discriminate validity. RESULTS: The sample consisted of 838 patients (62.3% were female), with mean age of 70.2 years (SD 8.4). A total of 55.5% patients underwent knee replacement. Given that the tool was elaborated by patients and orthopaedic surgeons, it shows a good content validity. The priority score was statistically different (P < 0.001) among the three urgency categories created. The scores of the three WOMAC dimensions showed differences (P < 0.001) by the three urgency categories created. The correlations between the priority score and WOMAC dimensions were 0.79 (function), 0.69 (pain) and 0.51 (stiffness). The correlations between WOMAC items and items from priority tool were greater (0.47-0.69) between items measuring similar constructs than those measuring different constructs (0.27-0.49). These data are similar in both joints. CONCLUSIONS: Results support the validity of the prioritization tool to be used with patients waiting for hip or knee replacement. (shrink)

Abordamos aquí unos aspectos, posiblemente los menos conocidos, de la dilatada vida de Fray Diego de Deza, como son los orígenes de su linaje en la gallega Terra de Deza y el afincamiento durante la segunda mitad del siglo XIV de la que fue la rama familiar de Toro, su ciudad natal. No perteneciendo a la hidalguía de mayor abolengo y riqueza de los linajes allí establecidos, sus méritos personales le labraron un futuro prometedor, primero por la cátedra docente que (...) ocupó en Salamanca y sus altas dotes como maestro y, además, por la confianza que los Reyes Católicos depositaron en él al nombrarlo preceptor del malogrado príncipe heredero don Juan, lo que le hizo emprender una envidiable carrera tanto eclesiástica como por sus servicios a la Corona. Nuestro objetivo aquí no ha sido otro que vislumbrar sus relaciones parentales y sociales, obviando su brillante cursus honorum en ese doble rol de servicio al altar y al trono. (shrink)

La filosofía de los pensadores "presocráticos" ha sido abordada frecuentemente desde una perspectiva ontológica o cosmológica. El presente trabajo propone situar las consideraciones ontológicas o cosmológicas de estos pensadores en un marco más amplio, determinado por lo que el autor llama la "lógica de las retribuciones". Esta perspectiva más abarcadora tiene la ventaja de poder integrar en la exposición de las primeras filosofías de Grecia algunos textos frecuentemente desatendidos, por considerarlos puros elementos mitológicos o literarios. Desde este punto de vista (...) se abren nuevas vías para entender las relaciones entre filosofía y religión, al tiempo que se muestran las intenciones prácticas de la filosofía en sus mismos orígenes.

La indagación del segundo Heidegger acerca del ser encuentra su maduración en la doctrina del Ereignis, un nuevo concepto «post-metafísico», según Vattimo, con el que el filósofo alemán trata de responder a la pregunta de qué es el ser una vez ha mostrado, en su primera etapa intelectual, la esencial diferenciación ontológica. El ser no es un ente, ni aquello fijo e inmutable que fundamenta lo ente. Ni de él puede decirse que es; el ser «se da». Y se da (...) al hombre en un acto de donación recíproca en la totalidad del acontecer histórico. Vattimo parte de esta idea para concluir que el ser es evento que orbita en la constelación del Ge-Stell, el destino de la época actual en cuanto forma de desocultar el ser, de desvelar la verdad, y convierte a Heidegger en precursor de la postmodernidad y de su pensiero debole.

One of the main challenges in medicine is to guarantee an appropriate drug supply according to the real needs of patients. Closed-loop strategies have been widely used to develop automatic solutions based on feedback variables. However, when the variable of interest cannot be directly measured or there is a lack of knowledge behind the process, it turns into a difficult issue to solve. In this research, a novel algorithm to approach this problem is presented. The main objective of this study (...) is to provide a new general algorithm capable of determining the influence of a certain clinical variable in the decision making process for drug supply and then defining an automatic system able to guide the process considering this information. Thus, this new technique will provide a way to validate a given physiological signal as a feedback variable for drug titration. In addition, the result of the algorithm in terms of fuzzy rules and membership functions will define a fuzzy-based decision system for the drug delivery process. The method proposed is based on a Fuzzy Inference System whose structure is obtained through a decision tree algorithm. A four-step methodology is then developed: data collection, preprocessing, Fuzzy Inference System generation, and the validation of results. To test this methodology, the analgesia control scenario was analysed. Specifically, the viability of the Analgesia Nociception Index as a guiding variable for the analgesic process during surgical interventions was studied. Real data was obtained from fifteen patients undergoing cholecystectomy surgery. (shrink)

The Air Quality Index (AQI) shows the state of air pollution in a unique and more understandable way. This work aims to forecast the AQI in Algeciras (Spain) 8 hours in advance. The AQI is calculated indirectly through the predicted concentrations of five pollutants (O3, NO2, CO, SO2 and PM10) to achieve this goal. Artificial neural networks (ANNs), sequence-to-sequence long short-term memory networks (LSTMs) and a newly proposed method combing a rolling window with the latter (LSTMNA) are employed as the (...) forecasting techniques. Besides, two input approaches are evaluated: using only the data from the own time series of the pollutant in the first case or adding exogenous variables in the second one. Several window sizes are employed (24, 28 and 72 hours) with ANNs and LSTMNAs. Additionally, several feature ranking methods are applied in the exogenous approach to select the most relevant lagged variables to feed the models. Results show how the proposed exogenous approach increases the performance of the prediction models. Besides, the newly proposed method LSTMNA provides the best performances in most of the cases evaluated. Hence, it constitutes an exciting alternative to standard LSTMs and ANNs to predict pollutants concentrations and, consequently, the AQI. (shrink)

From the standpoint of the school settings, sport participation constitutes a key strategy concerning the manifestation of positive behaviors that result from the development of personal and social responsibility. Based on the TPSR model, the goal of this study was to evaluate the effects of an intervention geared toward teaching life skills through sport to youngsters who had been committed. The participants were evaluated before and after the intervention. After the initial evaluation, they were randomly assigned to the experimental and (...) control groups. The experimental group took part in the community football program, while the control group attended physical education classes not based on the TPSR model. The experimental model consisted of 3 weekly sessions over the course of 6 weeks, which totaled 18 sessions. This investigation supplied empirical evidence concerning the potential of community sport programs in the teaching and development of life skills deemed necessary for an adequate reintegration of such at-risk youngsters. The model was shown to be valid both in stimulating changes of attitudes and in promoting the adherence to socially positive behaviors. The effectiveness of the model, as well as its unique approach, make its application attractive to both the youngsters and the professionals. This program facilitates the training of youngsters to act, in the sense of promoting both their autonomy and the acquisition of a system of ethics and moral values within a culture of responsibility for how decisions affect the individual and the community. Finally, this intervention generated empirical support in favor of the argument that sport constitutes a unique opportunity within the educational process to establish values, beliefs, attitudes, and practical habits pertaining relationships and cooperation that generate social responsibility in individuals.

In the current digital era, the borders amongst firms are getting blurred when it comes to value creation. Therefore, the traditional configuration of the value chain is frequently replaced by other ones which include the collaborative participation of different agents. Within this context, global value chains, where the value activities are located in different countries, and industrial clusters, which combine competition and cooperation, are attracting a growing attention of both business leaders and scholars in the recent years. Through a bibliometric (...) analysis, this paper disentangles the intellectual and conceptual structure of the research topic of industrial clusters and global value chains. Results show the multidisciplinary character of the topic, including papers published in different areas, such as business, regional studies and world development, as well as its close link with aspects like innovation, regional development, governance or organization. Finally, this study remarks the research lines that could attract more attention in the immediate future. (shrink)

Psychosocial work factors are implicated in the development of stress and job satisfaction. This relationship has been scarcely studied in so-called singular activities, as is the case of professional drivers. This cross-sectional study of 601 professional drivers assesses psychosocial risks and job satisfaction using Copenhagen Psychosocial Questionnaire and Overall Job Satisfaction questionnaire models. The values of the psychosocial scales of professional drivers were compared with thresholds values of the Spanish working population. The relationships of the psychosocial scales with the level (...) of job satisfaction were examined using logistic regression models, adjusted for age, gender, length of driving license and years of experience. In general, professional drivers have an unfavorable psychosocial environment compared to the average Spanish workers. The relationship between psychosocial scales and job satisfaction is observed, with the most influential variables being the meaning and development of work, integration in the company, social relations, esteem and level of psychological demands.

Fuṣūṣ al-ḥikām é uma das obras mais importantes do místico e pensador andaluz Muḥyi al-dīn Ibn 'Arabī (1165-1240). Esse texto, um dos melhores exemplos do pensamento medieval, é um autêntico repositório simbólico do conhecimento da tradição abraâmica. Ao mesmo tempo, o mestre murciano atribui essa obra a uma experiência visionária na forma de conhecimento descendente do qual ele se sentia um mero transcritor. Este trabalho se propõe a analisar simbolicamente os desafios de um livro visionário e, por outro lado, os (...) recursos que ele utiliza: os profetas como arquétipos para justificar a antropologia transcendental do ser humano perfeito (insān al-kāmil) e a metodologia da "cadeia ligada" para legitimar um conhecimento além da razão.

Cancer is a chronic disease that causes the most deaths in the world, being a public health problem nowadays. Even though breast cancer affects the daily lives of patients, many women become resilient after the disease, decreasing the impact of the diagnosis. Based on a positive psychology approach, the concept of co-vitality arises understood as a set of socio-emotional competencies that enhance psychological adaptation. In this sense, emotional intelligence is one of the main protective factors associated with resilience. However, it (...) is not always as beneficial as it seems, and can lead to collateral effects on psychological adjustment. Given this controversy, this study aims to find the specific processes through which the dimensions of Perceived Emotional Intelligence can act as a risk or protective factor in the development of resilience. The total sample was 167 women, 46.7% were breast cancer survivors, and 53.3% were healthy controls. The selection of women with breast cancer carries out randomly, recruited through the Oncology Units. The sample completed measures of resilience and PEI, through Resilience Scale and TMMS-24. The results showed that breast cancer survivors showed higher age and greater levels of resilience and mood repair than healthy women. The mediation analysis revealed that breast cancer survival and PEI predicted 28% of the variance of resilience. The direct effects showed that emotional clarity and mood repair increased resilience levels. Although breast cancer did not predict resilience directly, it does through mood repair by an indirect process. Besides, the analysis showed that emotional attention played a role in vulnerability, decreasing mood repair, and resilience. These research support theories that point to a possible dark side of PEI, thus, a great level of emotional attention makes dark the positive effect of mood repair and personal growth if a clear perception of emotions does not complement it. These results provide empirical support concerning the need to work complementary each dimension of PEI to avoid unwanted effects on intrapersonal adjustment. (shrink)

Designated bishop of Silves, diocese of Faro, Algarve, in 1334, D. Alvaro Pelayo entered in conflict with Alfonso IV (1325-57), the King of Portugal, sending him two letters in that one can notice that there he also had to defend the jurisdictional autonomy of the spiritual power, in order to the centralizing politics that the king, following his father’s steps, D. Dinis (1279-1325), gave continuity, with the purpose of restricting the political space of the high Lusitanian clergy. Past some few (...) years, (1347) for the same reason, the conflict of the relationships of power among the two authorities increased. Our purpose here is double: to analyze the historical facts related with the two mentioned conflicts, well as the aspects doctrinal contents in the two referred letters, with view to show the thought coherence and attitude of D. Alvaro Pelayo. (shrink)

Este trabajo es una lectura estética-semiótica de la ṣalāt islámica. A menudo considerada como oración por influencia de la colonialización intelectual, diversos trabajos actuales han puesto en duda esta definición. Este trabajo pretende mostrar esta práctica desde una perspectiva estética, etnoescenológica y semiótica con el fin de resaltar otros elementos antropológicos de la performance como las transferencias energéticas, la vinculación con la naturaleza o el uso profundo de los sentidos.

The article investigates one of the positions of Zubiri with respect to the problem ofGod, which the author terms the “cosmic way” to distinguish it from the better-known “wayof relegation”. In his “cosmic way,” Zubiri elaborates an argument for the existence of Godstarting from the data of the physics of his time, in particular, the cosmology of the “BigBang.” Undoubtedly, the “way of relegation” is the most characteristic of Zubiri’s philosophy, and the one which is in best agreement with the (...) whole corpus of his work. And theadvantages of the “way of relegation” stand out especially when it is compared to the “cosmic way”. But this does not mean that the “cosmic way” cannot be considered criticallyfrom the point of view of its own merits.El artículo investiga uno de los planteamientos de Zubiri en torno al problema de Dios,y que el autor denomina “vía cósmica” para distinguirla de la más conocida “vía de la religación”. En su vía cósmica, Zubiri elaboraba un argumento sobre la existencia de Dios apartir de los datos de la física de su tiempo, especialmente a partir de la cosmología del “BigBang”. Sin embargo, la vía de la religación es la más característica de la filosofía de Zubiri,y la más acorde con el conjunto de su filosofía. Las ventajas de la vía de la religación destacan especialmente cuando se la compara con la vía cósmica. Ello no obsta para que la víacósmica de Zubiri pueda ser considerada críticamente desde el punto de vista de sus propios méritos. (shrink)

The importance of professional competence lies in the effective application of job-oriented knowledge and skills which guarantee one’s successful adaptation to the work. This study analyzes the perception of the importance of physical activity and sports professionals’ competence in working with individuals with disabilities in Spain. As a descriptive quantitative study, face-to-face interviews were conducted through a survey to extract the data. The sample consisted of 214 PAS professionals working with people with disabilities. According to the results, the analyzed constituents (...) of professional competence are important for adequate performance, with the exception of competences of leadership and use of new technologies. It was also found that the perceived importance of each element of professional competence varies according to age, experience and training. Based on the obtained results, the degree of importance of each constituent of professional competence and its implication for the access of people with disabilities to high-quality physical activity and sports services was determined.

En este artículo se propone una línea de continuidad entre el pensamiento de Zubiri y el de Ellacuría en lo que se refiere a la ¿realidad histórica¿, partiendo de la crítica que hace el primero a una concepción aristotelizante de la historia, que caracterizaría al pensamiento moderno, entendida como actualización de posibilidades. A este respecto, se analiza la fecundidad de la perspectiva de Ellacuría respecto del significado de la globalización y su tesis de la civilización de la pobreza contrastándola con (...) el análisis de Karl Otto Apel.
