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.

Knowledge of diverse sexual motivations can have profound implications for our comprehension of the causes, correlations, and consequences of sexual behavior. This study had two objectives: on the one hand, to determine the different motives why young Spanish university students have sex and their relationship with different sociodemographic and psychosexual variables and sexual behavior; on the other hand, to review and improve the psychometric properties of the Sexual Motivations Scale and validate it in Spanish. Participants were 805 university students of (...) both sexes, aged between 18 and 26 years, who completed a battery of online questionnaires. Significant associations were found between young people's sexual motives, especially the motives of coping, peer pressure, and enhancement, the sociodemographic variables, sexual behavior, and psychosexual variables. Also, a new structure of the Sexual Motivations Scale was proposed, with the elimination of the factor of Self-Affirmation. The discussion highlights the relevance of the results obtained due to their implications in the promotion of sexual health, in addition to achieving the first instrument validated in Spanish for the evaluation of sexual motivations.

We propose a characterization of mathematical experiments in terms of a setup, a process with an outcome, and an interpretation. Using a broad notion of process, this allows us to consider arithmetic calculations and geometric constructions as components of mathematical experiments. Moreover, we argue that mathematical experiments should be considered within a broader context of an experimental research project. Finally, we present a particular case study of the genesis of a geometric construction to illustrate the experimental use of hand drawings (...) and computers in mathematical practice. (shrink)

El coaching ejecutivo ha dado lugar a numerosos desarrollos de orientación básicamente prescriptiva. Una perspectiva crítica y con base empírica puede permitir ir más allá de la retórica del coaching e identificar las tensiones y las contradicciones de los procesos de coaching en un contexto organizacional, como entorno relacional y cultural. El objetivo de este trabajo es acercarnos críticamente al coaching ejecutivo individual en la práctica, estableciendo las diferencias entre lo preconizado por las teorías y los expertos del coaching y (...) lo que se hace en las empresas. Mediante 50 entrevistas en profundidad a coaches y coachees, identificamos cuatro grandes discursos sobre el coaching ejecutivo: a) herramienta de crecimiento personal; b) relación diádica; c) resolución de problemas en equipos de trabajo; y d) mecanismo de cambio organizacional. El análisis muestra las tensiones y las contradicciones ad intra y entre los discursos y, con ello, la importancia de considerar el contexto organizacional. (shrink)

IntroductionThis study aimed to evaluate, in adults with mild cognitive impairment, the brain atrophy that may distinguish between three AT biomarker-based profiles, and to determine its clinical value.MethodsStructural MRI was employed to evaluate the volume and cortical thickness differences in MCI patients with different AT profiles, namely, A−T−−: normal AD biomarkers; A+T−−: AD pathologic change; and A+T++: prodromal AD. Sensitivity and specificity of these changes were also estimated.ResultsAn initial atrophy in medial temporal lobe areas was found in the A+T−− and (...) A+T++ groups, spreading toward the parietal and frontal regions in A+T++ patients. These structural changes allowed distinguishing AT profiles within the AD continuum; however, the profiles and their pattern of neurodegeneration were unsuccessful to determine the current clinical status.ConclusionsMRI is useful in the determination of the specific brain structural changes of AT profiles along the AD continuum, allowing differentiation between MCI adults with or without pathological AD biomarkers.

With this volume of the series Logic, Epistemology, and the Unity of Science edited by S. Rahman et al. a challenging dialogue is being continued. The series’ first volume argued that one way to recover the connections between logic, philosophy of sciences, and sciences is to acknowledge the host of alternative logics which are currently being developed. The present volume focuses on four key themes. First of all, several chapters unpack the connection between knowledge and epistemology with particular focus on (...) the notion of knowledge as resulting from interaction. Secondly, new epistemological perspectives on linguistics, the foundations of mathematics and logic, physics, biology and law are a subject of analysis. Thirdly, several chapters are dedicated to a discussion of Constructive Type Theory and more generally of the proof-theoretical notion of meaning.Finally, the book brings together studies on the epistemic role of abduction and argumentation theory, both linked to non-monotonic approaches to the dynamics of knowledge.

Although entrepreneurial intention has been widely studied using cognitive models, we still lack entrepreneurial vocation and, therefore, lack disruptive innovations. Entrepreneurship scholars have some understanding of the reasons underlying this weakness, although there is much room for improvement in our learning concerning how to promote entrepreneurship among university students, especially in the transformed context of digital technologies. This paper focuses on the early stages of start-up, and in particular seeks to evaluate what role social and psychological factors play in the (...) development of entrepreneurial intentions. Drawing on network theory, we consider the impact of social networks on entrepreneurial intention. Specifically, we analyze the influence of two types of social networks: face-to-face and online social networks, with the latter proving especially important in digital transformations. In addition, based on affective congruency theory, we relate affect with entrepreneurial intention. Particularly, we evaluate the influence of positive and negative dispositional affectivity on the formation of entrepreneurial intentions. Finally, since affect and emotions can also be related with social relationships, we analyze whether dispositional affectivities influence entrepreneurial intention through the mediation effect of social networks. Using structural equation modeling, we confirm the impact of both online and face-to-face social networks, as well as positive dispositional affectivity on entrepreneurial intention for 589 higher education students in Spain. However, negative dispositional affectivity is not seen to influence entrepreneurial intention. Furthermore, both face-to-face and online social networks are influenced by positive dispositional affectivity. Moreover, these two types of networks can even partially mediate the relationship between positive dispositional affectivity and entrepreneurial intention. Positive dispositional affectivity can thus influence entrepreneurial intention in two different ways: directly and indirectly through both face-to-face and online social networks. This study provides further insights and adds to the literature on affect, social networks, and entrepreneurial intention. From a broader perspective, we also contribute to the literature on disruptive innovations by explaining how the development of entrepreneurial intentions would have positive consequences for university students vis-à-vis achieving these disruptive innovations.

El presente trabajo analiza el concepto de ciudadanía y algunas de sus implicaciones en el marco de las democracias occidentales actuales. Partiendo de la premisa de que ser ciudadano supone una determinada relación con un Estado, se revisan algunas de las fundamentaciones clásicas del concepto y se concluye que lo relevante es la variedad de derechos sustantivos que el Estado reconoce a sus sujetos políticos. La esencia de ser ciudadano se desvela revisando el repertorio de derechos a los que su (...) estatuto jurídico permite acceder. Se reflexiona desde ese punto de partida sobre el momento actual, advirtiendo que la pérdida de peso político de los Estados merma derechos ciudadanos y provoca la desafección hacia la política tradicional creando nuevas formas de participación política, cuyos riesgos y virtualidades son destacados. Finalmente, se señala la necesidad de generar estructuras de poder en las que los ciudadanos tengan la posibilidad de ejercer sus derechos políticos y cómo dicha pretensión está ligada al ideal del ciudadano cosmopolita y a instituciones internacionales que den cabida a la diversidad cultural. Se concluye apuntando el papel decisivo que juega la reflexión ética en el reconocimiento de valores mínimos que permitan alcanzar acuerdos que se traduzcan en derechos universalizables. (shrink)

El artículo trata de abordar algunos aspectos de articulación entre pluralismo y justicia. Más concretamente, las posibilidades de profundizar en una teoría de la justicia que sea capaz de acoger en un mismo marco político a ciudadanos de culturas y valores heterogéneos. Ello conduce a destacar algunas de las deficiencias de posturas relativistas y monistas y a defender una posición que parta de la posición del liberalismo político y la supere con el fin de conducir a un marco político ni (...) neutral ni perfeccionista.

Objective: The aim of this research was to study the mediation of body dissatisfaction, physical self-concept, and body mass index (BMI) on the relationship between physical activity and self-concept in adolescents. Materials and Methods: A sample of 652 Spanish students between 12 and 17 years participated in a cross-sectional study. Physical self-concept and general self-concept were assessed with the Physical Self-Concept Questionnaire (CAF), body dissatisfaction with the Body Shape Questionnaire (BSQ), and physical activity was estimated with the International Physical Activity (...) Questionnaire (IPAQ-SF). BMI was utilized as a measurement of body composition. Structural equation modeling was used to assess the results. Results: The resulting models showed good fit indexes. Physical activity had a positive and indirect effect on self-concept (β = 0.29, p < 0.01) and direct effects on dissatisfaction (β = -0.26, p < 0.01) and physical self-concept (β = 0.20, p < 0.01). BMI had a direct effect on dissatisfaction (β = 0.31, p < 0.01) and on physical self-concept (β = -0.10, p < 0.01) and an indirect effect on general self-concept (β = -0.24, p < 0.01). However, it was only associated with physical activity in males, playing a mediating role between physical activity and body dissatisfaction. Conclusion: Physical activity can help individuals to achieve a positive self-concept and promote psychological well-being in adolescents through the improvement of physical perceptions and body satisfaction. The importance of BMI, body dissatisfaction, and physical self-concept on the configuration of the self-concept are also emphasized. Educational policymakers and Physical Education teachers should implement strategies to promote physical activity in the schools and provide a Quality Physical Education programs to increase physical activity during adolescence.

This paper presents a method to compute a posteriori probability intervals when the initial conditional information is also given with probability intervals. The right way to make an exact computation is with the associated convex set of probabilities. Probability trees are used to represent these initial conditional convex sets because they greatly save the space required. This paper proposes a simulated annealing algorithm, which uses probability trees to represent the convex sets in order to compute the a posteriori intervals.

There is currently much debate in the economic literature about whether ethical investment involves a financial sacrifice or premium. One of the most common methods of testing this compares the financial performance of ethical investment funds with that of other funds not considered “socially responsible” or ethical. The majority of these research studies evaluate the performance of the ethical funds according to classic measures, whereby different financial markets, in different countries and for different periods of time serve as reference for (...) evaluation. The ultimate conclusion of all of these studies is that there are no significant differences between the performance results of one type of funds and the other. In Spain, ethical investment funds are still an incipient sector of investment. To date, the Spanish market has not been included in any type of analysis of these characteristics. Therefore the main objective of this article is to compare the financial performance of ethical investment funds to that of other funds in the Spanish retail market. We propose the aggregate type of analysis as the Spanish ethical investment funds have experienced a weaker development in comparison to those of other developed countries. In the first step we suggest the financial performance to be compared by style analysis since the asset distribution of the Spanish Social Return Investment (SRI) funds differs from the European trend. In particular, we use the multifactor regression model with style benchmarks. We found that their financial performance is in all cases superior or similar to that achieved by the rest of the funds. In the second step, to achieve a more robust and homogeneous comparison, we used the bootstrap method, comparing ethical and non-ethical fund subsamples by homogeneous groups. No significant differences between these two types of funds have been found. Thus, if we assume the positive o neutral effect of ethical investment on investor utility in the retail Spanish market the financial and social performance (FSP) of ethical funds will be, in aggregate, superior to the FSP achieved by conventional funds. In conclusion, the financial performance of ethical mutual funds in Spain is no sacrifice. (shrink)
