This article proposes a guideline to develop an ontology of software. The first section gives a brief introduction to the importance of such ontology as a possible conceptual grounding for the philosophy of software, philosophy of computing and philosophy of information. The second section presents the background of the scope of this article in terms of both a symbolic and materialistic approach to software. The third section deploys the basic guidelines with the expositions of the two dimensions of software: the (...) serial dimension and the structural dimension. The first dimension consists of three series, while the second in the exposition of the structure of any program. The fourth and last section will deal with a better understanding of what we can call the digital universe. (shrink)

En este artículo se afirma que la idea de ‘virtual’ o de ‘virtualidad’ pertenece a una perspectiva teórica que pretende explicar los componentes del fenómeno de la sociedad tecnológica de hoy en día. En primer lugar, la perspectiva digital es explicada en su estructura ontológica básica: códigos binarios que organizan un set de elementos físicos o un hardware de acuerdo con reglas lógicas. Por ende, la idea de sociedad en red, comunicación virtual y seres humanos digitales son conceptos que no (...) aprehenden realmente el problema de la tecnología digital en nuestra sociedad. Una perspectiva digital asume la necesidad de entender la tecnología digital en su funcionamiento físico, lo que permite una representación completa del problema y permite el análisis crítico subsecuente de la perspectiva virtual. En segundo lugar, la perspectiva virtual es analizada desde la perspectiva digital hasta en sus principales suposiciones metafísicas: la simulación, como un ideal moral presupuesto, y la funcionalidad, como una idea instrumental presupuesta. Finalmente, la conclusión explica las posibilidades dadas por la perspectiva digital en aras de asumir nuevos retos en el universo digital, en contraste con una perspectiva virtual que podría pre-limitar dichas posibilidades para que necesidades previas sean satisfechas. Por ende, este artículo, antes que mostrar un argumento bien definido, exhorta a la reorientación de nuestras nociones acerca de lo virtual y de lo digital. (shrink)

Los avances científico-tecnológicos han abierto una brecha en cuanto a los tratamientos médicos y los valores morales que deben sustentar la atención de salud. El profesional de enfermería no está exento de estos peligros, por lo que se ha generado un nuevo modelo ético que se integre al proceso de atención de enfermería. Con el objetivo de determinar los conocimientos y opiniones de estos profesionales, del área de cirugía de mínimo acceso, acerca de la aplicación del modelo en el contexto (...) de estos servicios, se diseñó una investigación de tipo observacional descriptiva con empleo de metodología cualitativa. Como técnica de exploración se usó la entrevista en profundidad, así como un panel de expertos para la construcción de la guía de entrevista. Se entrevistó a 34 enfermeras que laboraban en el Centro Nacional de Cirugía de Mínimo Acceso durante el período del estudio. Se concluye que la práctica de la cirugía de mínimo acceso es propicia para que médicos y enfermeras hagan una mayor observancia del derecho de autonomía de los pacientes. Se reconoce la capacidad de este personal para tomar decisiones independientes de los médicos en cuanto a las acciones de cuidado, lo que implica una mayor responsabilidad. Scientific and technological advances have opened a gap between medical treatments and the moral values that should support health care. The nurse is not exempt from these dangers. As such, a new ethical model that integrates to the process of nursing care has emerged. In order to determine the knowledge and opinions of the professionals who work in minimal access surgery services on the implementation of this model, a descriptive, observational study was designed utilizing qualitative methodology. In-depth interviewing was used as the primary testing technique. A panel of experts from the National Center of Minimal Access Surgery was consulted to develop the interview guide. Thirty-four nurses from the National Center for Minimal Access Surgery were interviewed over the course of the study period. Results suggest that the setting of minimal access surgery is conducive to medical professionals making greater observance of the right to patient autonomy. The ability of this staff to make independent decisions regarding medical care action is recognized, which implies greater responsibility. (shrink)

Traditional games are considered agents of enculturation. This article explores the procedure to access the cultural meanings transmitted in a traditional game. The goal is to understand what children aged 6–11 make of the game called ‘the chained bear’ and to compare the meanings retrieved with those of different traditional versions of the game. For such a purpose, through an exploratory cross-sectional study, cartoons depicting people playing the game were exhibited and viewers were asked to interpret them as a drama (...) play, as well as contributing a title, a plot and saying how they would name the characters. The results show that, beyond the individual images that each child created in their mind, most of them coincided in stories about harassment and defense and theft and protection. These plots match those of the ludic tradition, showing that the actions evoke different pictures to each individual, but share common cultural meanings in turn. The study shows a procedure to access the meanings that traditional games transmit and confirms that games contain pieces of culture, which makes them agents of enculturation. (shrink)

Self-control is deemed crucial for reasons-responsive agency and a key contributor to long-term wellbeing. But recent studies suggest that effortfully resisting one’s temptations does not contribute to long-term goal attainment, and can even be harmful. So how does self-control improve our lives? Finding an answer requires revising the role that overcoming temptation plays in self-control. This paper distinguishes two forms of self-control problems: temptation (the presence of a strong wayward motivation) and apathy (the lack of commitment-advancing motivation). This distinction makes (...) it possible to separate negative self-control (aimed at overcoming temptation) from positive self-control (aimed at overcoming lack of motivation). The paper argues that temptation should not play a central role in our conception of self-control, since overcoming temptation is neither necessary nor sufficient for successful self-control.

Background: COVID-19 has taken many lives worldwide and due to this, millions of persons are in grief. When the grief process lasts longer than 6 months, the person is in risk of developing Complicated Grief Disorder. The CGD is related to serious health consequences. To reduce the probability of developing CGD a preventive intervention could be applied. In developing countries like Mexico, the psychological services are scarce, self-applied interventions could provide support to solve this problem and reduce the health impact (...) even after the pandemic has already finished.Aims: To design and implement a self-applied intervention composed of 12 modules focused on the decrease of the risk of developing CGD, and increasing the life quality, and as a secondary objective to reduce the symptomatology of anxiety, depression, and increase of sleep quality. The Intervention Duelo COVID follows the principles of User Experience and is designed according to the needs and desires of a sample of the objective participants, to increase the adherence to the self-applied intervention, considered one of the main weaknesses of online interventions.Methods: A Randomized Controlled Trial will be conducted from the 22nd of December of 2020 to the first of June 2021. The participants will be assigned to an intervention with elements of Cognitive Behavioral Therapy, Acceptance and Commitment Therapy, Mindfulness and Positive Psychology. The control group will be a wait-list condition, that will receive the intervention 1.5–2 months after the pre-measurement were taken. The Power Size Calculation conducted through G*Power indicated the need for a total of 42 participants, which will be divided by 21 participants in each group. The platform will be delivered through responsive design assuring with this that the intervention will adapt to the screen size of cellphones, tablets, and computers.Ethics and Dissemination: The study counts with the approval of the Research Ethics Committee of the Autonomous University of Ciudad Juárez, México, and it is registered in Clinical Trials. The article is sent and registered in clinical trials before the recruitment started. The results will be reported in future conferences, scientific publications, and media. (shrink)

Introducción: Los cambios biológicos, sicológicos, económicos y sociales que se observan durante el envejecimiento conllevan a pensar que en los ancianos existe una serie de factores que favorecen la aparición de una depresión. Objetivo: evaluar la efectividad de una intervención sicológica para disminuir la depresión en adultos mayores de la Casa de abuelos "Dr. Diego Tamayo Figueredo", de Puerto Padre, en el período de noviembre de 2013 - mayo de 2014. Material y métodos: se realizó un estudio de intervención sicológica (...) en una muestra de 12 adultos mayores de la casa de abuelos. Se aplicó un programa de intervención sicológica, así como la Escala de Depresión Geriátrica para realizar la valoración antes y después de la intervención. Se empleó el modelo Cognitivo- Conductual de Beck. Los datos fueron tratados según la estadística descriptiva. Resultados: el porciento más elevado de pacientes correspondió al grupo de ancianos con edades entre los 60 y 90 años de edad. Respecto al sexo, el más frecuente es el masculino. El asma bronquial, la hipertensión arterial y la diabetes Mellitus representaron el mayor porciento de antecedentes patológicos personales. Conclusión: la intervención sicológica resultó efectiva pues se logró disminuir a leve los niveles iniciales de depresión establecida y los considerados con leve a no depresión, por lo tanto se afirma que con su aplicación fue modificado el estado emocional de los adultos mayores que se implicaron en la muestra. Introduction: Biological, psychological, financial and social changes observed during aging lead to think that there is a series of factors that favor the appearance of depression in senior citizens. Objective: Assessing the effectiveness of a psychological intervention in order to reduce depression in senior citizens from "Dr. Diego Tamayo Figueredo" Senior Citizens' House, Puerto Padre, from November 2013 to May 2014. Material and methods: A psychological intervention study was conducted on a sample of 12 senior citizens from the house. A psychological intervention program as well as the Geriatrics Depression Scale were applied before and after the intervention in order to make the assessment. The Beck's cognitive-behavior model was used. Data was processed according to descriptive statistics. Results: The highest percentage of patients corresponded to a group of seniors between 60 and 90 years of age. Regarding sex, males are more common. Bronchial asthma, arterial hypertension and diabetes mellitus represented the highest percentage of personal pathological history. Conclusion: The psychological intervention proved to be effective since initial established depression levels were reduced to minor and those considered as minor were reduced to no depression ; therefore, it is stated that its application modified the state of mind of the senior citizens involved in the sample.

En la ciudad de Medellín se hace uso de herramientas y dispositivos, en el marco de la llamada Gestión Social, para ejecutar importantes obras para el llamado desarrollo urbano, que bien pueden configurar una “Gestión social del despojo”, en el marco de una “Planeación institucional de la miseria y el desarraigo”, generando víctimas ya no del conflicto armado sino del desarrollo. Es necesario problematizar esta suerte de modelo de desarrollo urbano, su gestión e implementación.

In lieu of an abstract, here is a brief excerpt of the content:The Knock at the Door: Utopian Dreams for Post-Covid TimesPedro Mora-Ramírez, María Amo-Hernández, and Paula García-RodríguezAnswering the Knock at the Door, Welcoming Utopian Futures, The Knock at the Door: Utopian Dreams for Post-Covid Times, May 21–24, 2023, University of Huelva, Spain, and University of Calgary, CanadaThe COVID-19 pandemic has fostered new adversities and vulnerabilities, prompting reflection on the economic, social, and political paradigms that endanger human and nonhuman (...) lives. For many, it was anxiety and uncertainty that “knock[ed] at the door”; for others, however, those same feelings of unease prompted one of hopefulness: reflecting on the possibilities for resilience and regeneration in the process of changing our vision of the world.1 The Knock at the Door conference brought contemporary utopianism to the forefront of thinking about how to respond to global crises while remaining attentive to other adversities of daily life. Scholars and artists answered the knock in an attempt to examine paths toward utopia, and to take advantage of the regenerative and resilient potential of the present.The conference was the culmination of author/activist Larissa Lai’s fellowship period at the University of Huelva. The 2022–23 María Zambrano Fellowship for the academic year2 allowed Lai to complete the project “Utopian Dreams for Post-Covid Times,” carried out in collaboration with the Huelva research group led by Professor Pilar Cuder-Domínguez, who hosted a number of online and in-person seminars on speculative fiction with Lai. The Knock at the Door conference, marking the end of Lai’s fellowship, created yet another space for scholars, artists, and critics to discuss the potential of utopian narratives. Lai asks: “What does our cultural moment require, and how can we get where we need to go from where we are? How can literature, especially speculative fiction literature, help us get from here to there?”3 [End Page 641] The intention of the conference was to encourage others to continue Lai’s work on how to imagine futures where human and posthuman beings need to remain vigilant to adversities. Utopian scholars, among others, might find the complications of “getting there from here” closely related to Lai’s conception of “insurgent utopias,” or “emergent insurgency.” They could find Lai’s concept of “insurgent utopianism” interesting as it lays the foundations of futurity in terms of crisis responses.The aim of the conference was to explore the imagination of better futures through utopian thinking and practice. In addition, it focused on “the knock at the door,” which is “a moment of contingent arrival... open to cooptation, destruction, bastardization, incorporation, death, or defusal.” Yet, it presents “the powerful possibility of critique—narratively or discursively, in its very materiality.”4 One way of doing this might be to look back at the past century of utopianism and ask who or what has been missing. The conference took up Lai’s idea of insurgent utopianism as a method of paving a path toward a multitude of dreams and actions, all shaped by the unique circumstances of one’s positionality.After the COVID-19 pandemic, the need for utopian thinking has become more pressing than ever. New horizons of hope must be created in the face of emerging anxieties. In a world where anthropocentrism is showing signs of its deadly potential, conference participants reflected on the relevance of the utopian imagination to political resistance and resilience building.Utopian Visions: Contesting Better Worlds in Neoliberal and Feminist UtopiasThe first two panels of the conference addressed the critique of two dominant theoretical (and interrelated) frameworks: capitalism and neoliberalism. Speakers reflected on both in light of theoretical interventions by theorists Rosi Braidotti and Francesca Ferrando. Panelists Benjamin Ghan and Marc Lynch reflected on how creative writers envision ideal worlds and temporalities. In Ghan’s view, utopian narratives create a symphony of voices historically excluded from the category of “the human”: women; LGBTQ+ people; Indigenous peoples. In a similar vein, Lynch described his own novel, A Wasp’s Waist, as highlighting the impossibility of imagining utopias within the capitalist paradigm—and thus the necessity of imagining futures beyond capitalism, and beyond...

The Chinese room argument has presented a persistent headache in the search for Artificial Intelligence. Since it first appeared in the literature, various interpretations have been made, attempting to understand the problems posed by this thought experiment. Throughout all this time, some researchers in the Artificial Intelligence community have seen Symbol Grounding as proposed by Harnad as a solution to the Chinese room argument. The main thesis in this paper is that although related, these two issues present different problems in (...) the framework presented by Harnad himself. The work presented here attempts to shed some light on the relationship between John Searle’s intentionality notion and Harnad’s Symbol Grounding Problem. (shrink)

RESUMEN Se aplicó una intervención socio sanitaria en el asentamiento rural El León de Camagüey basada en los resultados de un estudio anterior, desde la comunicación social, educativa, así como aspectos socioculturales evaluados que permitieron la realización de este estudio. Su objetivo fue implementar una estrategia de intervención basada en acciones sociales y educativas colectadas en un manual que organizó contenidos de antropología socio cultural, psicología, sociología de la salud y trabajo social comunitario, la que fue conducida por profesionales de (...) enfermería como prestadores, cuyo encargo social les asigna una mayor permanencia e intercambio con los pobladores, potenciándose el trabajo comunitario a partir de febrero de 2016,como etapa de sostenibilidad. La investigación constituyó un diseño mixto, con un estudio cuasi experimental sin grupo control combinado con métodos cualitativos. La evaluación final efectuada en el periodo 2017-2018 exhibió modificaciones positivas en indicadores de las historias clínicas familiares de los pobladores, repercutiendo en el Análisis de la Situación de Salud, realizado en abril de 2018 y el entorno comunitario. Se demostró la importancia de la aplicación de la estrategia de intervención comunitaria desde las disciplinas de las ciencias sociales, por el personal de enfermería como agente de cambio de desarrollo local y protagonista de sostenibilidad. ABSTRACT A social sanitary intervention was applied in the rural establishment El León of Camagüey, based on social and educational actions collected in a manual that organized social cultural anthropology contents, psychology, sociology of the health and community social work, which was led by infirmary professionals like lenders, whose social order assigns a major permanence and exchange of them with the settlers. The investigation constituted a mixed design, with a study quasi experimentally without control group combined with qualitative methods. The final evaluation carried out in the period 2017-2018 exhibited positive modifications in indicators of the familiar clinical history of the settlers, what reverberated in the Analysis of the Situation of Health, carried in April, 2018 and the community environment. It was demonstrated the importance of the application of the strategy of community intervention from the disciplines of the social sciences, by the infirmary personnel as change agent of local development and protagonist of sustainability.

In this paper we present a new framework of idealization in biology. We characterize idealizations as a network of counterfactual and hypothetical conditionals that can exhibit different “degrees of contingency”. We use this idea to say that, in departing more or less from the actual world, idealizations can serve numerous epistemic, methodological or heuristic purposes within scientific research. We defend that, in part, this structure explains why idealizations, despite being deformations of reality, are so successful in scientific practice. For illustrative (...) purposes, we provide an example from population genetics, the Wright-Fisher Model. (shrink)

El presente artículo recapacita sobre las reformas normativas acontecidas en las últimas décadas respecto al uso racional de los medicamentos, y las medidas operadas en torno a la disminución del gasto farmacéutico. En este contexto, debe destacarse el elevado coste de las terapias biológicas y las dificultades de acceso a las mismas —especialmente en los países en vías de desarrollo—. Los medicamentos biosimilares son poseedores de garantías sanitarias análogas —semejantes o equivalentes— a los medicamentos de referencia, pero no están sometidos (...) a una protección por una patente y facilitan la accesibilidad a los pacientes, así como al reparto equitativo de los recursos terapéuticos. Además, algunos de ellos están incluido en la lista de medicamentos esenciales de la Organización Mundial de la Salud (OMS).Asimismo, se examina el papel de los medicamentos biosimilares como esenciales y la posibilidad de mejorar el acceso equitativo a estos recursos sanitarios a través de la prestación farmacéutica.

The scientific literature has shown Mondragon Corporation, with 65 years of history, as a clear example that cooperativism can be highly competitive in the capitalist market while being highly egalitarian and democratic. This cooperative group has focused on its corporate values of cooperation, participation, social responsibility, and innovation. Previous scientific research reports its enormous transformative and emancipatory potential. However, studies on the effects of various types of worker participation on competitiveness and workers’ psychological wellbeing in this cooperative group exist to (...) a lesser extent. Specifically, one aspect that needs further empirical research and that represents a competitive advantage for Mondragon is the degree of commitment and emotional attachment that can be observed in the people who work there. For this reason, this article aims to identify key elements of the democratic participation of workers in these cooperatives that relate to the development of organizational commitment. Based on a communicative and qualitative approach, data collection included 29 interviews to different profiles of workers from eight different cooperatives of the Corporation. Through this research methodology, the participants interpret their reality through egalitarian and intersubjective dialogue because their voices are considered essential to measure the social impact. This study found three different ways in which the democratic participation of worker-members in management and ownership contributes to developing affective organizational commitment among those working in Mondragon cooperatives, generating positive psychological and economic outcomes for both workers and cooperatives.

In the international context of a progress toward more inclusive educational systems and practices, the role of Special Education teachers is being transformed. From an inclusive perspective, these professionals increasingly support students and their teachers in the mainstream classroom, avoiding segregation. However, Special Education teachers often struggle to reach and support all students with special needs and their teachers to provide quality inclusive education. For this reason, more research is still needed on in-service training strategies for the inclusion of students (...) with special needs that effectively translate into evidence-based school practices that improve the education of all students. This article analyses the impact of two evidence-based dialogic training programs of Special Education teachers working in mainstream schools carried out in Mexico during the 2018–2019 school year. Through in-depth interviews with participants, it was identified how, after the training, teachers increasingly grounded their actions on scientific evidence and promoted interactive learning environments that improved the educational inclusion of their students with special needs. This training also became the venue to make evidence-based educational actions available to other students without special needs, improving the quality of education provided to all students.

Se realizó una investigación cualitativa, entre octubre de 2015 y junio de 2016, en la Casa de Abuelos No. 2 de Santa Clara con el objetivo de caracterizar la representación social de la sexualidad de los adultos mayores. Se seleccionó una muestra de 24 adultos mayores. Se utilizaron técnicas como: observación, entrevista, debate grupal, asociación de palabras, de cuestionamiento del núcleo central y la triangulación de datos. Como resultados se determinó que en la representación de la sexualidad se observó un (...) campo estructurado y un contenido que se aleja de su significado. Se concluyó que la representación social de la sexualidad de los adultos mayores se identificó con las relaciones sexuales, con el acto sexual. Las informaciones que poseen carecen de calidad y denotan un carácter prejuiciado y estereotipado. Manifestaron actitudes de rechazo hacia la sexualidad lo que se explicó por: el desconocimiento, la inadecuada relación entre sexualidad y reproducción, la existencia de prejuicios sociales y asociar el envejecimiento con la enfermedad. With the aim of characterizing the social representation of sexuality in senior citizens, a qualitative research was carried out from October 2015 to June 2016 in Grandparents House No. 2 in Santa Clara City. A sample of 24 people was selected. Methods such as observation, interview, group debate, words association, central core questioning technique and data triangulation were used. It was determined that in the representation of sexuality there is a structured field and a content that goes away from its meaning. Social representation of sexuality in senior citizens was identified with sexual relationships and with sexual intercourse. They lack quality information and show a prejudiced and stereotyped character. They expressed rejection attitudes towards sexuality which were based on: ignorance, inadequate connection between sexuality and reproduction, existence of social prejudice and association of aging with disease.

We examine ethical considerations in access to facial transplantation (FT), with implications for promoting health equity. As a form of vascularised composite allotransplantation, FT is still considered innovative with a relatively low volume of procedures performed to date by a small number of active FT programmes worldwide. However, as numbers continue to increase and institutions look to establish new FT programmes, we anticipate that attention will shift from feasibility towards ensuring the benefits of FT are equitably available to those in (...) need. This manuscript assesses barriers to care and their ethical implications across a number of considerations, with the intent of mapping various factors relating to health equity and fair access to FT. Evidence is drawn from an evolving clinical experience as well as published scholarship addressing several dimensions of access to FT. We also explore novel concerns that have yet to be mentioned in the literature. (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)

In this work, we focus on the problem of selecting low-level heuristics in a hyperheuristic approach with offline learning, for the solution of instances of different problem domains. The objective is to improve the performance of the offline hyperheuristic approach, identifying equivalence classes in a set of instances of different problems and selecting the best performing heuristics in each of them. A methodology is proposed as the first step of a set of instances of all problems, and the generic characteristics (...) of each instance and the performance of the heuristics in each one of them are considered to define the vectors of characteristics and make a grouping of classes. Metalearning with statistical tests is used to select the heuristics for each class. Finally, we used the Naive Bayes to test the set instances with k-fold cross-validation, and we compared all results statistically with the best-known values. In this research, the methodology was tested by applying it to the problems of capacitated vehicle routing and graph coloring. The experimental results show that the proposed methodology can improve the performance of the offline hyperheuristic approach, correctly identifying the classes of instances and applying the appropriate heuristics in each case. This is based on the statistical comparison of the results obtained with those of the state of the art of each instance. (shrink)
