The aims of this research were twofold: first, to compare the levels of organisational harmony between family and non-family firms and, second, to study the influence of organisational harmony on family firms’ performance (profitability, longevity and group cohesion). Starting from a definition of organisational harmony as a value and considering the importance of the management of organisational values, we use the main topics indicated by the general literature (organisational climate, trust and participation) to analyse organisational harmony, as well as three (...) other topics for performance (profitability, survival and group cohesion). Results indicate that family firms have higher levels of these three qualities than non-family firms, and that the levels of trust, participation and organisational climate have a positive and significant influence on the performance of family firms. These results can be understood as a consequence of the influence of family social capital on organisational social capital and so on the performance of family businesses. From the perspective of institutionalism, the higher levels of harmony existing in family businesses are a reflection of the pressures that the owning family as an institution exercises on the organisational social capital in its companies.

Multi-Task Learning tries to improve the learning process of different tasks by solving them simultaneously. A popular Multi-Task Learning formulation for SVM is to combine common and task-specific parts. Other approaches rely on using a Graph Laplacian regularizer. Here we propose a combination of these two approaches that can be applied to L1, L2 and LS-SVMs. We also propose an algorithm to iteratively learn the graph adjacency matrix used in the Laplacian regularization. We test our proposal with synthetic and real (...) problems, both in regression and classification settings. When the task structure is present, we show that our model is able to detect it, which leads to better results, and we also show it to be competitive even when this structure is not present.

Training for sustainable development is an educational challenge of prime importance. Physical activity and sports in natural environments provide training committed to sustainability and environmental education. The objective of this study was to assess the effects of an undergraduate training program in Physical Activities and Sports in Natural Environments concerned with sustainable development. A total of 113 students from the Autonomous University of Madrid who are studying a Bachelor’s Degree in Physical Activity and Sports Sciences and a Master’s Degree in (...) Teacher Training for Secondary Education and High School were involved. Specifically, we aimed to assess the impact of this training program on three dimensions related to Environmental Education. Its effect was also examined bearing in mind students’ sex, age and educational profile. Mixed-methods were used: for the quantitative approach, data were collected with the Environmental Attitude in Physical Activities in Natural Environments validated scale; for the qualitative approach individual reflective diaries completed by students that attended the program were analyzed. The results show positive effects on the students regarding the three dimensions of Environmental Education, for both the sportive and educational training profiles. The quantitative results do not present significant differences concerning the gender variable, although the qualitative information shows that female students perceived a greater environmental sensitivity during their practices. Regarding the age variable, significant differences are found in the youngest students with an educational profile. To conclude, the study ratifies that the program carried out generated improvements in terms of knowledge, behaviors and attitudes toward the environment and sustainable development. Future research should use larger samples and consider other variables related to education for sustainability. (shrink)

Traducción crítica de las dos cuestiones_ quodlibetales_ dedicadas por Enrique de Gante al origen causal de la imposibilidad, precedida de un estudio introductorio que analiza ambas cuestiones en el marco general de su ontología relacional. En la primera (VI.3), Enrique concluye que la imposibilidad de algo proviene _ex parte rei_; mientras que en la segunda (VIII.3), concluye que la imposibilidad de algo proviene _ex parte dei_. El estudio de ambas cuestiones muestra, por una parte, la continuidad y la dependencia de (...) la segunda cuestión respecto de la primera y, por otra, la debilidad de la distinción propuesta por Enrique entre la constitución formal de la _res_ y su posibilidad objetiva, así como la originalidad y el valor de la noción de nada (_purum nihil_) que logra precisar en ellas.

Objective: To measure the stability of life-sustaining treatment preferences amongst older people and analyse the factors that influence stability. Design: Longitudinal cohort study. Setting: Primary care centres, Granada (Spain). Eighty-five persons age 65 years or older. Participants filled out a questionnaire with six contexts of illness (LSPQ-e). They had to decide whether or not to receive treatment. Participants completed the questionnaire at baseline and 18 months later. Results: 86 percent of the patients did not change preferences. Sex, age, marital status, (...) hospitalisation, and self-perception of health and pain did not affect preferences. Morbidity and the death of a relative did. Conclusion: Stability of preferences of older persons in relation to end-of-life decisions seems to be more probable than instability. Some factors, such as the death of a relative or the increase in morbidity, can change preferences. These findings have implications for advance directives (ADs) and advance care planning. (shrink)

8 March, now known as International Women’s Day, is a day for feminist claims where demonstrations are organized in over 150 countries, with the participation of millions of women all around the world. These demonstrations can be viewed as collective rituals and thus focus attention on the processes that facilitate different psychosocial effects. This work aims to explore the mechanisms involved in participation in the demonstrations of 8 March 2020, collective and ritualized feminist actions, and their correlates associated with personal (...) well-being and collective well-being, collective efficacy and collective growth, and behavioral intention to support the fight for women’s rights. To this end, a cross-cultural study was conducted with the participation of 2,854 people from countries in Latin America and Europe, with a retrospective correlational cross-sectional design and a convenience sample. Participants were divided between demonstration participants and non-demonstrators or followers who monitored participants through the media and social networks. Compared with non-demonstrators and with males, female and non-binary gender respondents had greater scores in mechanisms and criterion variables. Further random-effects model meta-analyses revealed that the perceived emotional synchrony was consistently associated with more proximal mechanisms, as well as with criterion variables. Finally, sequential moderation analyses showed that proposed mechanisms successfully mediated the effects of participation on every criterion variable. These results indicate that participation in 8M marches and demonstrations can be analyzed through the literature on collective rituals. As such, collective participation implies positive outcomes both individually and collectively, which are further reinforced through key psychological mechanisms, in line with a Durkheimian approach to collective rituals.

The study investigated the influence of resilience and dispositional optimism on, first, emotional distress and, second, the intention to self-isolate, experienced by people with a lower and higher illness risk, during the lockdown imposed in Spain during the first COVID-19 wave. These effects were investigated against the background of the Health Belief Model. A convenience sample of N = 325 participants completed an online survey including an ad-hoc questionnaire measuring the HBM core factors: Perceived health threat, and perceived quarantine benefits (...) and costs. Self-efficacy and perceived social pressure were also measured. Based on reviews regarding pandemic outbreaks, quarantine benefits were conceptualized as the perceived effectiveness and solidary contribution of self-isolating in line with the quarantine protocols. Quarantine “psychosocial” costs were conceptualized as a composite of perceived boredom, loneliness, and economic concerns. Findings revealed an asymmetrical pattern of results so that people at higher risk were more distressed by the perceived severity of getting infected whereas people at lower risk were more distressed by the psychosocial costs. Moreover, resilience and optimism were more “protective” against distress within the lower and higher risk groups, respectively. In addition, quarantine benefits and self-efficacy promoted the intention to self-isolate within both groups. However, optimism hindered such intention. This finding is discussed in the light of links between dispositional optimism and optimistic bias; the underestimation of experiencing negative events, which can relax the perceived health risk. Based on these findings, communication campaigns should prioritize information about the effectiveness of the implemented preventive behaviors rather than the costs of not implementing them, and be cautionary in encouraging excessive optimism.

The key problems and challenges connected with the Covid-19 pandemic in the field of education in sub-Saharan Africa are described in this paper. The study is based on the information collected from teachers and parents during the lockdown. The main problems connected with the organization of distance learning, such as the availability and accessibility of electricity and stable communications, were described. The main questions connected with the support of e-learning such as unequal access to distance education platforms and tools and (...) readiness of teachers of public and private schools were described. Key social and demographic challenges and threats to sustainable e-learning, such as critical overload of teachers, child mobilization for domestic tasks, age, ethnic and gender-based harassment and violence were analyzed. It was found that the main risks are the rapid and uncontrolled commercialization of education and the decline of public schools, which leads to a decrease in the quality of education and increasing inequality. It was concluded that pandemic-induced risks in education are non-linear and heterogeneously spatially, temporally, and socially distributed. The successful strategy of these risks reduction aimed at sustainable education should be based on transition plans, which must include not only the development of sustainable education but also the fighting against inequality.

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)

El presente estudio se desarrolla en el Noroeste Mexicano en las comunidades de Guaymas, Sonora y Puerto San Carlos, Baja California Sur. Dichas comunidades representan la pesca de sardina en el Proyecto denominado “Unidades Representativas de Producción del Sector Pesquero y Acuícola” desarrollado por SAGARPA y AGROPROSPECTA, tiene como objetivo evaluar políticas públicas gubernamentales en los mercados agroalimentarios de México incluyendo recientemente al sector pesquero. Los datos se obtuvieron por medio de paneles de información donde participaron productores de sardina (...) con datos del año 2008 como base. Se trabajó con el modelo de simulación económica desarrollado para México MexSim, desarrollado en la Universidad de Texas A&M con indicadores económicos de ingresos y egresos. Los resultados obtenidos muestran que la URP desarrollada en Guaymas proyecta una situación económica general favorable para la actividad, mientras que la URP desarrollada en San Carlos proyecta una situación económica general moderada.

Este texto es el resultado de un ejercicio crítico de lectura, de mi lectura de Derrida como lector de Freud. A partir del análisis que hace Derrida en su ensayo "Freud y la escena de la escritura", discuto la necesidad de radicalizar algunas de las consecuencias que se siguen de la analogía que Freud establece entre el aparato psíquico y cierta máquina de escritura. Uno de los fenómenos que se desprenden de pensar la psique como un texto es que el (...) sujeto habita incesantemente en la tensión de un entre: entre la herencia y lo porvenir. Este entre devela una temporalidad sui géneris donde los tiempos pasado, presente y futuro se mezclan y se funden. This essay is the result of a critical reading exercise, of my reading of Derrida as a reader of Freud. From Derrida's analysis in his text "Freud and the Scene of Writing", I argue the necessity of radicalizing some consequences that emerge from the analogy established by Freud between the psychic apparatus, and a certain writing machine. One of the phenomena that thinking the psyche as a text points to is that the subject relentlessly dwells in the tension of a between: between the inherited and what is to come. This between unveils a sui generis temporality where past, present and future mingle and fuse. (shrink)

The aim of this paper is to show that Philitas of Cos did not write bucolic poetry. The Scholia in Theocritus draw on ancient commentaries, which quoted Philitas, but no feature of the bucolic poetry is assigned to Philitas. Propertius opposes Philitas’ love poetry to the bucolic, and there is no clue that Longus Sophista or Vergil knew of Philitas’ bucolic poetry. Moreover, it seems that ancient poets and erudites were persuaded of the Sicilian (i. e. Theocritean) origin of the (...) bucolic poetry. (shrink)

This editorial provides an overview of topics covered in Empedocles: European Journal for the Philosophy of Communication 13:2. Adopting ‘criticality’ as an interpretative framework, four research articles are introduced which discuss relevant matters in ethics, rhetoric, political philosophy and cultural critique from a communicational standpoint.

This book argues for a new reading of the political and ethical through the literatures of Argentina, Chile, and Paraguay from 1970-2000. Carlos Amador reads a series of examples from the last dictatorship and the current post-dictatorship period in the Southern Cone, including works by Augusto Roa Bastos, Roberto Bolaño, Ceferino Reato, Horacio Verbitsky, Nelly Richard, Diamela Eltit, and Willy Thayer, with the goal of uncovering the logic behind their conceptions of belonging and rejection. Focusing on theoretical concepts that (...) make possible the formation of any and all communities, this study works towards a vision of literature as essential to the structure of ethics. (shrink)

A destination’s image is a critical factor in tourists’ perceptions and evaluations of said destination. This paper analyzes the formation of the tourist destination image of Segóbriga Archeological Park, a cultural destination located in the province of Cuenca (Spain) that holds great heritage value. To this end, the paper adopted a multidimensional approach and used PLS-SEM to analyze the destination image, taking into account not only its cognitive and affective components, but also the unique image component. The latter has received (...) less attention in the literature and is a novel factor among cultural destinations. The results show that this component is essential to the overall image of an archeological destination, but is not influenced by information sources. (shrink)

The aim of this paper is to demonstrate that the tragic poets of the fifth century BC used an engine called ekkyklema in order to reveal the scenes supposed to take place inside. I think I can indicate a passage, that clearly demonstrates the use of such an engine (Eur. Her. 1028 ff.), since the chorus’ words are otherwise unintellegibile. Comic poets used this engine only for paratragic purpose, because the distinction inside/outside was not relevant for comedy.

The aim of this paper is to undermine structural realism by testing the soundness of its three main theses. The first section presents the epistemic and ontic forms of structural realism. The following section defends that if scientific theories represent the structure of the world, structural realism needs a general account of representation. Representation is the crux of structural realism. Section 3 argues that structure/ontology distinction collapses. Mathematical structures are ontologyladen. Lastly, section 4 is devoted to analyse whether there is (...) a retention of mathematical structure across theory change. (shrink)

Since Seligman's 1971 statement that the vast majority of phobias are about objects essential to the survival of a species, a multitude of laboratory studies followed, supporting the finding that humans learn to fear and detect snakes (and other animals) faster than other stimuli. Most of these studies used schematic drawings, images, or pictures of snakes, and only a small amount of fieldwork in naturalistic environments was done. We address fear preparedness theories, and automatic fast detection data from mainstream laboratory (...) data and compares it with ethobehavioural information relative to snakes, predator-prey interaction, and snakes’ defensive kinematics strikes in order to analyse their potential matching. From this analysis four main findings arose, namely that: 1) Snakebites occur when people are very close to the snake and are unaware or unable to escape the bite; 2) Human visual detection and escape response is slow compared to the speed of snake strikes; 3) In natural environments, snake experts are often unable to see snakes existing nearby; 4) animate objects in general capture more attention over other stimuli and dangerous but recent objects in evolutionary terms are also able to be detected fast. The issues mentioned above pose several challenges to evolutionary psychology-based theories expecting to find special-purpose neural modules. The older selective habituation hypothesis (Schleidt, 1961), that prey animals start with a rather general predator image from which specific harmless cues are removed by habituation might deserve reconsideration.
