La sostenibilidad es un modelo de desarrollo en el que las acciones presentes no deben comprometer el futuro de las generaciones venideras, y se vincula con un desarrollo económico y social respetuoso con el medio ambiente. El enoturismo supone un modo de ocio placentero que conjuga el placer del disfrute de los vinos con aspectos relacionados con la cultura, como conocimientos sobre elaboración de los vinos, sobre los ecosistemas asociados a los viñedos, sobre expresiones artísticas, etc. Todo ello constituye parte (...) del desarrollo cultural de las regiones vitivinícolas, en las que la cultura del vino ha marcado su devenir histórico y lo que son hoy en día. Por tanto, se puede afirmar que la cultura del vino, y su uso a través de las experiencias enoturísticas, está claramente relacionada con la sostenibilidad social, económica, ambiental y cultural de los territorios.

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)

This work focuses on the application of machine learning techniques to assist the clinicians in the administration of analgesic drug during general anaesthesia. Specifically, the main objective is to propose the basis of an intelligent system capable of making decisions to guide the opioid dose changes based on a new nociception monitor, the analgesia nociception index. Clinical data were obtained from 15 patients undergoing cholecystectomy surgery. By means of an off-line study, machine learning techniques were applied to analyse the possible (...) relationship between the analgesic dose changes performed by the physician due to the hemodynamic activity of the patients and the evolution of the ANI. After training different classifiers and testing the results under cross validation, a preliminary relationship between the evolution of ANI and the dosage of remifentanil was found. These results evidence the potential of the ANI as a promising index to guide the infusion of analgesia. (shrink)

Automatic control of physiological variables is one of the most active areas in biomedical engineering. This paper is centered in the prediction of the analgesic variables evolution in patients undergoing surgery. The proposal is based on the use of hybrid intelligent modelling methods. The study considers the Analgesia Nociception Index to assess the pain in the patient and remifentanil as intravenous analgesic. The model proposed is able to make a one-step-ahead prediction of the remifentanil dose corresponding to the current state (...) of the patient. The input information is the previous remifentanil dose, the ANI variable and the electromyogram signal. Modelling techniques used are Artificial Neural Networks and Support Vector machines for Regression combined with clustering methods. Both training and validation were done with a real dataset from different patients. Results obtained show the potential of this methodology to calculate the drug dose corresponding to a given analgesic state of the patient. (shrink)

One of the measures adopted by the government of Spain during the COVID-19 pandemic has been the elimination of face-to-face classes in all universities, requiring that all teachers had to conduct their classes in an online mode. The objective of this article is to study how this adaptation among university teachers affected their job performance due to the technostress that they may have suffered. Based on the person-environment misfit theory, the sample consisted of 239 teachers from face-to-face and online universities (...) in Spain who were asked to identify the type of technostress, feelings of technostress, and impact on job performance as a result of online teaching due to the COVID-19 pandemic. Results show that teachers who suffered the most from the negative consequences of technology have been female teachers from face-to-face universities who are older, have more years of experience, and consequently, hold a higher position. Despite previous results none of the above variables have been significant in explaining the decline in job performance during confinement. It was also observed that although the effect on job performance was similar for online teachers as well as face-to-face teachers, the variables that explained this effect were different. For the online teachers, there was a misfit between the demands and resources, which are explained based on the previous theory. Teachers from face-to-face universities pointed to the lack of instructions from their organization, along with subjective feelings of techno-inefficacy, as the reasons behind the decline in job performance during the lockdown period. Looking ahead to future research on the incorporation of information and communications technology in teaching work, it is necessary to consider variables associated with technostress, both objective and subjective, in order to increase the effectiveness of integrating emerging technology into teaching work.

Aberrations introduced by the atmospheric turbulence in large telescopes are compensated using adaptive optics systems, where the use of deformable mirrors and multiple sensors relies on complex control systems. Recently, the development of larger scales of telescopes as the E-ELT or TMT has created a computational challenge due to the increasing complexity of the new adaptive optics systems. The Complex Atmospheric Reconstructor based on Machine Learning is an algorithm based on artificial neural networks, designed to compensate the atmospheric turbulence. During (...) recent years, the use of GPUs has been proved to be a great solution to speed up the learning process of neural networks, and different frameworks have been created to ease their development. The implementation of CARMEN in different Multi-GPU frameworks is presented in this paper, along with its development in a language originally developed for GPU, like CUDA. This implementation offers the best response for all the presented cases, although its advantage of using more than one GPU occurs only in large networks. (shrink)

Closed-loop administration of propofol for the control of hypnosis in anesthesia has evidenced an outperformance when comparing it with manual administration in terms of drug consumption and post-operative recovery of patients. Unlike other systems, the success of this strategy lies on the availability of a feedback variable capable of quantifying the current hypnotic state of the patient. However, the appearance of anomalies during the anesthetic process may result in inaccurate actions of the automatic controller. These anomalies may come from the (...) monitors, the syringe pumps, the actions of the surgeon or even from alterations in patients. This could produce adverse side effects that can affect the patient postoperative and reduce the safety of the patient in the operating room. Then, the use of anomaly detection techniques plays a significant role to avoid this undesirable situations. This work assesses different one-class intelligent techniques to detect anomalies in patients undergoing general anesthesia. Due to the difficulty of obtaining real data from anomaly situations, artificial outliers are generated to check the performance of each classifier. The final model presents successful performance.

En Metafísica M.2 Aristóteles desarrolla diversas objeciones en contra de la introducción platónica de objetos matemáticos como substancias no-sensibles, separadas de las sensibles. Su primera objeción es de carácter doble. En primer lugar, Aristóteles argumenta que la postulación de objetos geométricos separados produce una acumulación absurda. En segundo lugar, sugiere que este argumento geométrico se puede extender al caso de las unidades y los números. En este trabajo me ocupo de explicar esta extensión aritmética. Los especialistas han interpretado esta extensión (...) de una manera que denomino “maximalista”. Aquí defiendo una interpretación distinta, “minimalista”. (shrink)

Este artículo de homenaje a la Profesora Yolanda Ruano se divide en dos partes. En la primera discuto las críticas que ella realizara a mi libro sobre la diosa Fortuna en las que avanzaba su propio análisis de las complejas relaciones entre razón y fortuna en el pensamiento occidental. En la segunda parte, desde el punto de vista del “giro icónico” en humanidades y ciencias sociales, analizo el caso concreto del auge y desaparición de la diosa Fortuna en la iconografía (...) política de la ciudad de Berlín. A lo largo del siglo XIX la diosa Fortuna desaparece de la escena berlinesa y es sustituida por la diosa Niké o Victoria, que popularmente se interpreta como un Ángel de la Victoria. Este es el marco de la infancia de Walter Benjamin, quien más tarde expresará su visión de la historia con un otro ángel completamente distinto, el Angelus Novus de Paul Klee. (shrink)

The primary goal of the present research was to determine the order of swimmers on a mixed relay team that would ensure the best performance in the Fédération Internationale de Natation World Championships held in Kazan, Budapest, and Gwangju. The data were obtained from database websites for the 4 × 100 m freestyle and 4 × 100 m medley official results,1 including 660 records from 188 entries of finals and 472 preliminary events. The results showed that the fastest swimmers were (...) located primarily in the first or second positions of the freestyle relay. The most successful gender strategy for the 4 × 100 m freestyle and for the 4 × 100 m medley relays was the order male-male-female-female, although no statistical differences were found for the medley relays. In the 4 × 100 m freestyle, the second and third relay legs had a statistical effect on the total relay time, whereas in the 4 × 100 m medley, all four relay legs had a statistical effect on the final performance, the weight of the four strokes being different in heats with respect to the final round. Also, a later position of the first female swimmer or the consecutive position of two female swimmers in the team order significantly affected the relay performance in specific events. Mixed relay events appeared to present specific strategies in comparison to traditional male- or female-only relay lineups. (shrink)

Forgiveness seeking after a relational transgression is an important aspect of relational repair from an interpersonal perspective, although it has received much less attention than the process of granting forgiveness. This research focuses on the victim's perspective of the transgressor's behaviors and how they are related to forgiveness and offense characteristics. This paper proposes a multidimensional concept of seeking forgiveness that includes four dimensions: apologies, restorative action, relational caring behaviors, and diverting behaviors. A questionnaire for assessing these dimensions was developed (...) and tested with a general population sample of 450 subjects. Participants recalled a specific offense and then answered a questionnaire about the perceived usefulness of different forgiveness-seeking behaviors, a forgiveness inventory, and several questions regarding the characteristics of the offense. Our results support the four-factor structure of the questionnaire. As the perceived intentionality of the offense increases, behaviors that are directly related to the transgression, such as apologies and restorative actions, are experienced as less useful for forgiveness. The more hurtful the offense, the less useful the diverting behaviors are. Behavior such as apologies and restorative action are related to a lower motivation for revenge, while all forgiveness-seeking behaviors are related to an increase in feelings of benevolence toward the offender.

Este artículo analiza la crisis de la República romana tardía, atribuida por los antiguos autores a la decadencia moral y a los vicios orientales y cómo Cicerón, defensor de las instituciones republicanas y de los boni, se enfrentó a los populares que buscaban reformas estructurales. Se destacan sus conflictos con Catilina, Clodio, Pisón y, especialmente, con Antonio. A lo largo de su carrera, Cicerón defendió su dignitas y argumentó que las virtudes cardinales propuestas por Platón y Panecio eran clave para (...) alcanzar la verdadera gloria. En las Filípicas, atacó a Antonio y apoyó a Octaviano, aunque este último terminó traicionándolo. Estos discursos polarizaron la política romana, mostrando, según Bruto, la falta de visión política de Cicerón. Para defenderse de los ataques por su condena a los catilinarios y promover reformas estatales, Cicerón recurrió a la filosofía y defendió los principios platónicos y estoicos, abogando por la creencia en una providencia divina, la importancia de las virtudes cardinales, el uso de la razón y la superioridad del derecho natural de inspiración divina sobre la ley humana. También criticó a los epicúreos por su rechazo a la política, negación de la providencia divina y búsqueda del placer. (shrink)

En las Filípicas, Cicerón utilizó una amplia variedad de invectivas para denigrar a Antonio, retratándolo como un individuo antisocial que encarnaba todas las taras morales y vicios. Lo describió como un enemigo del Estado y un tirano que aspiraba a la autocracia y buscaba eliminar a los boni, defensores de la República. Estos insultos se analizan a lo largo del artículo y se observa en ellos una inversión de las virtudes cardinales descritas por Cicerón. Según Cicerón, estas virtudes eran las (...) cualidades que un estadista debía poseer, tal y como se detalla en su obra De Officiis, que escribió al mismo tiempo que pronunciaba las Filípicas.

Disregard of gender and of women’s contributions in the higher education curriculum is still a widespread phenomenon. Building on feminist institutionalism, this article explores the forms and types of resistance that efforts to engender the higher education curriculum must contend with and discusses the ways in which resistance to curricular reform is entrenched in a web of both gender-specific and apparently gender-neutral academic informal rules. In doing so, the authors use empirical evidence collected by an action-research project undertaken at a (...) faculty of political and social sciences in a Catalan public university. The Spanish case is intriguing because mainstreaming gender in higher education has been prescribed by various national and regional laws that are nonetheless poorly implemented. The article also reflects on the positive feedback loop action-research projects can facilitate within gendered institutions such as universities and pinpoints the role of feminist agency in counteracting resistance to institutional change.

Childhood obesity, linked to a sedentary lifestyle and an unbalanced diet, is one of the main problems in today’s Western societies. In this sense, the aim of the study was to analyze students’ perceived satisfaction in physical education classes with learning strategies and engagement in learning and critical thinking as determinants of healthy lifestyle habits. The study involved 2,439 high school students aged 12–18 years (M= 14.66,SD= 1.78). Structural equation modeling was conducted to analyze the predictive relationships between the study (...) variables. The results showed that teaching, teaching mastery, and cognitive development are precursors to deep thinking on the part of students, indicators of the adoption of healthy lifestyle habits. These results reflect the importance of the methodology adopted by the teacher in order to positively influence the students’ habits. (shrink)

Over the past decades, the psychological science has accumulated a large corpus of empirical knowledge about police interviews, deception detection, and suspects’ confessions. However, it is unclear whether European police forces’ practices and beliefs are consistent with recommendations derived from this empirical literature. The study described in this report is part of a larger research project examining European police investigators’ practices and beliefs. An online survey was administered to Guardia Civil (n = 89) and Policía Nacional investigators (n = 126). (...) The survey inquired about the length, frequency and electronic recording of interviews, the suspects’ use of their right to remain silent, investigators’ self-reported skills in distinguishing between truthful and deceptive statements, their estimates of the frequency of (false) confessions, and their use of specific interview tactics. The outcomes provide insights into investigators’ knowledge and practices, highlight specific needs, and allow for a comparison between European and North American police forces. (shrink)

Aim: The presence of noise in urban environments is rarely considered a factor that causes damage to the environment. The primary generating source is transportation means, with vehicles being the ones that affect cities the most. Traffic noise has a particular influence on the quality of life of those who are exposed to it and can cause health alterations ranging from annoyance to cardiovascular diseases. This study aims to describe the relationship between the traffic noise level and the perceived annoyance (...) in the inhabitants of a city on the Northern Border of Mexico. The work carried out in a city represents the vulnerability characteristics: economic, social, and migratory of its sizable portion of the inhabitants. Due to that, it is impossible to identify precisely the number of residents as the number of vehicles in circulation.Methods: The streets and avenues with an annual average daily traffic of more than 1,000 vehicles were considered for the measurement of traffic noise. The equipment used was a vehicle gauge with non-invasive speed radar; type I integrating sound level meters, with their respective gauges and tripods. A questionnaire was applied to people living within 250 m of the streets and avenues in which the noise was measured.Results: The noise measurement found a parameter of LAeq estimated for 12 h during the day, exceeding 70 dBA. The data received from the questionnaire were statistically tested by using Pearson's correlation tests. A total number of 2,350 people were participated, of whom 1,378 were women and 972 were men. The age of participants is ranged from 18 to 75 years. The overall perception of traffic noise annoyance identified that 1,131 participants responded “Yes” as they considered the noise annoying. Participants who responded “No” as well as those who responded “Do not know” resulted in a total of 1,219 people.Conclusion: The results show that the population is desensitized to traffic noise and does not perceive it as an annoyance. The flow of vehicles and the type of vehicles are the significant factors for the propagation and increase in the traffic noise levels. Women present a considerable appreciation of traffic noise perception instead of younger people who demonstrate a higher tolerance to high-level exposure. This reflects the lack of information of the population around the noise problem and its effects. (shrink)

Fall detection is a challenging task that has received the attention of the research community in the recent years. This study focuses on FD using data gathered from wearable devices with tri-axial accelerometers, developing a solution centered in elderly people living autonomously. This research includes three different ways to improve a FD method: an analysis of the event detection stage, comparing several alternatives, an evaluation of features to extract for each detected event and an appraisal of up to 6 different (...) clustering scenarios to split the samples in subsets that might enhance the classification. For each clustering scenario, a specific classification stage is defined. The experimentation includes publicly available simulated fall data sets. Results show the guidelines for defining a more robust and efficient FD method for on-wrist 3DACC wearable devices. (shrink)

This volume has 41 chapters written to honor the 100th birthday of Mario Bunge. It celebrates the work of this influential Argentine/Canadian physicist and philosopher. Contributions show the value of Bunge’s science-informed philosophy and his systematic approach to philosophical problems. The chapters explore the exceptionally wide spectrum of Bunge’s contributions to: metaphysics, methodology and philosophy of science, philosophy of mathematics, philosophy of physics, philosophy of psychology, philosophy of social science, philosophy of biology, philosophy of technology, moral philosophy, social and political (...) philosophy, medical philosophy, and education. The contributors include scholars from 16 countries. Bunge combines ontological realism with epistemological fallibilism. He believes that science provides the best and most warranted knowledge of the natural and social world, and that such knowledge is the only sound basis for moral decision making and social and political reform. Bunge argues for the unity of knowledge. In his eyes, science and philosophy constitute a fruitful and necessary partnership. Readers will discover the wisdom of this approach and will gain insight into the utility of cross-disciplinary scholarship. This anthology will appeal to researchers, students, and teachers in philosophy of science, social science, and liberal education programmes. 1. Introduction Section I.

Bentley et al.--O’Brien bypass the relevance of emotions in decision-making, resulting in a possible over-simplification of behavioral types. We propose integrating emotions, both in the north-south axis (in relation to cognition) as well as in the west-east axis (in relation to social influence), by suggesting a Z axis, in charge of registering emotional depth and involvement.

Background: Serious games have shown positive results in increasing motivation, adherence to treatment and strengthening the therapeutic alliance in multiple psychiatric disorders. In particular, patients with impulse control disorders and other disorders in which the patient suffers from inhibitory control deficits have been shown to benefit from serious games.Aim: The aim of this study was to describe the characteristics and to evaluate the usability of a new serious videogame, e-Estesia. This serious videogame was designed to improve emotion regulation in patients (...) with gambling disorder. Preliminary results from a pilot sample are also reported.Method: A pilot sample of 26 patients undergoing treatment for GD was recruited. Participants used e-Estesia on a tablet, which was connected to a thoracic band that sent heart rate and heart rate variability data to the videogame platform in order to provide biofeedback. The System Usability Scale was completed by patients to determine the usability of e-Estesia.Results and Discussion: e-Estesia performed comparatively well for all the explored groups. Around 84.6% of the patients endorsed that it was easy to use. Female patients with GD presented higher HRV during the use of the serious videogame compared to men. (shrink)

Hasta mediado s del siglo pasado, el tema que nos ocupa, la presencia de Cristo en los sacramentos, se resumía y concentraba, po r no deci r que se agotaba, en la presencia real eucanstica.
