Attention-deficit hyperactivity disorder is one of the most common neurodevelopmental disorders in children and adolescents. People who have this disorder are characterized by presenting difficulties in the processes of sustained attention, being very active, and having poor control of their impulses. Despite the high prevalence of this disorder and the existence of various tests used for its diagnosis, few data are available regarding the usefulness and diagnostic validity of these tools. Given the difficulties that these subjects present in executive functions, (...) the aim of this study was to evaluate whether the Neuropsychological Assessment of Executive Functions battery for Children allows to establish specific profiles of executive performance for people with attention-deficit hyperactivity disorder. The sample was made up of 197 participants of both sexes, aged between 6 and 12 years age. A nonexperimental design was followed, using a comparative descriptive study method. The results indicated that the scales of phonological fluency, color path, rings, and interference are the most associated with the diagnosis of ADHD, providing data on inhibition, mental flexibility, sustained and selective attention, planning, verbal fluency, and working memory, among others. The practical implication of these results is in line with providing support in the clinical diagnosis that is carried out in children’s mental health units. In addition, the ENFEN tool can be valued as a suitable psychometric instrument in the psychoeducational field, helping professionals in a school environment to be more aware of the areas of cognitive development in which a student diagnosed with ADHD will have more difficulties and, in doing so, providing more adjusted and effective psychopedagogical measures when it comes to supporting students in their adaptation to the school environment.

Previous research has shown positive relationships between fitness level and different cognitive abilities and academic performance. The purpose of this study was to explore the relationships between logical–mathematical intelligence and mathematical competence with physical fitness in a group of pre-adolescents. Sixty-three children from Castro del Río, aged between 11 and 12 years, participated in this research. The Superior Logical Intelligence Test and the EVAMAT 1.0–5 battery were used. Physical fitness was evaluated by the horizontal jump test, the 4×10 meter speed–agility (...) test, and the Course Navette test. The analyses showed positive relationships between physical fitness with logical–mathematical intelligence and mathematical competence. Specifically, linear regression analyzes indicated that the 4×10 speed–agility test significantly predicted mathematical competence and the horizontal jump test significantly predicted logical–mathematical intelligence. These results are in agreement with previous research, highlighting the importance of improving physical fitness from an early age due to its benefits for intellectual and academic development.

Children and adolescents are not indifferent to the dramatic impact of the COVID-19 pandemic, and the need to be forced to live in confinement. The change in life to which they have been abruptly subjected forces us to understand the state of their mental health in order to adequately address both their present and future needs. The present study was carried out with the intention of studying the consequences of confinement on anxiety, sleep routines and executive functioning of 1,028 children (...) and adolescents, aged from 6 to 18 years, residing in Spain to; assess if there are differences regarding these consequences in terms of sex and age; how anxiety affects executive functioning in males and females; and to examine the possible correlations between the measured variables. For this purpose, an online questionnaire containing five sections was designed: the first section gathers information on sociodemographic and health data, while the following sections gather information from different standardized scales which measure anxiety, sleep and executive functions, whose items were adapted in order to be completed by parents, and/or legal guardians. The statistical analyzes carried out highlights significant differences in executive functioning between males and females. In turn, in regards to age, greater difficulties were detected in anxiety in the 9 to 12 age group and greater sleep disturbances between 13 and 18 year olds. On the other hand, significant differences were found in intra-sexual executive functioning depending on whether they presented greater or lesser anxiety, with executive functioning being more tendentiously maladjusted in males than in females, revealing a significantly relevant effect size. Positive correlations are obtained between state anxiety and sleep and executive functioning alterations. Finally, through Path Analysis, it is verified that state anxiety is the variable with the greatest weight within the model that would explain the alteration in the executive functioning of the present sample.

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)

In this article, I use a number of remarks made by Eugene Wigner to defend the claim that the nature of the connection between symmetries and conservation laws is different in quantum and in classical mechanics. In particular, I provide a list of three differences that obtain between the Hilbert space formulation of quantum mechanics and the Lagrangian formulation of classical mechanics. I also show that these differences are due to the fact that conservation laws are not the only consequence (...) that symmetries have in quantum mechanics and to the fact that, in classical mechanics, the connection between symmetries and conservation laws does not always obtain.

This article discusses some of the claims of the earlier and later versions of the Contemporary Theory of Metaphor (CTM) and addresses some of the criticism that has been leveled against it. It is argued that much of this criticism arises from common misconceptions as to the real claims made by the theory. However, CTM is still in need of further exploration and empirical support. In this connection, we identify some areas where research is still needed and supply our own (...) developments. We argue for a more complex classification of metaphor types, which takes into account various complementary taxonomic perspectives, including the nature of source and target and the genericity and complexity of the metaphoric operation. We also explore metaphor in relation to cognitive prominence and conceptual interaction issues. Finally, we deal with the problem of constraints on metaphor and make a proposal for three complementary kinds of constraint. (shrink)

In this article, we offer a detailed study of two important episodes in the early history of high-energy physics, namely the development of the Chew and the Nambu-Jona-Lasinio models. Our study reveals that both models resulted from the combination of an old Hamiltonian, which had been introduced by earlier researchers, and two new approximation methods developed by Chew and by Nambu and Jona-Lasinio. These new approximation methods, furthermore, were the key component behind the models’ success. We take this historical investigation (...) to support two philosophical theses about the manner in which scientific modelling operates in high-energy physics. Both of these theses run counter to a view that is commonly accepted among philosophers of science: the view that all approximations can be embedded within an equivalent idealized system, and that whatever role the former might play in scientific modelling is therefore parasitic on the much more substantial work performed by the latter. Our first thesis, which we call “Distinctness,” states that approximation methods constitute an independent category of theoretical output from idealized systems. We thus believe that approximations and idealized systems constitute two independent types of objects, both of which are essential to the practice of modelling. Our second, more radical thesis is called “Content Determination.” Our claim here is that approximation methods can in fact be essential to assigning determinate physical content to the idealized systems with which they jointly operate. As we show, this is due to the fact that quantum field theory allows for a very thin characterization of idealized systems only, making the use of approximations necessary to supply additional content. We conclude the paper with a few reflections about the manner in which our two theses can be used to articulate David Kaiser’s views on the “vanishing of scientific theory” in physics after WWII.

La idea de “clasicismo” es una de las categorías más usadas en el mundo de las artes y de la estética filosófica. Sin embargo, la variedad de sus usos ha ocasionado que el término presente dificultades de interpretación y ambigüedades a quienes estudian el arte o la literatura clasicistas. El presente artículo se propone introducir algo de claridad y distinción en la discusión sobre la idea de “clasicismo”. Para ello, nos ocupamos, en primer lugar, de las cuestiones que conciernen a (...) su génesis histórica, disociándolo del concepto parejo, pero esencialmente diferente, de lo clásico. En segundo lugar, ofrecemos una caracterización de su estructura mediante una sistematización de sus cuatro sentidos principales tal y como se usan habitualmente en la bibliografía sobre el tema. De esta forma, el clasicismo se nos presenta como el problema de articular las diferentes conceptualizaciones filosóficas que se han adoptado sobre lo clásico. (shrink)

Recientemente fallecido, Pierre Aubenque consagró la mayor parte de su trayectoria a la interpretación del aristotelismo. Su apuesta por reconsiderar el sentido y la función de la metafísica aristotélica ha puesto de relieve la dignidad inherente a la tarea del historiador de la filosofía, cuya aproximación crítica al pasado exige la actualización de un singular compromiso intelectual. La nítida visión que tenía de los desafíos a los que debía responder la filosofía del s. XX, la participación en múltiples debates y (...) su entrega a la docencia universitaria, reaparecen hoy bajo los rasgos de un coraje bien reconocible en sus intervenciones. (shrink)

Background During the first weeks of March 2020 in Spain, the cases of severe respiratory failure progressively increased, generating an imbalance between the clinical needs for advanced life support (ALS) measures and the effective availability of ALS resources. To address this problem, the creation of triage committees (TC) was proposed, whose main function is to select the best candidates to receive ALS. The main objective of our study is to describe the clinical characteristics of the patients evaluated by the TC (...) of the Alcorcón Foundation University Hospital (AFUH) during the first wave of SARS CoV-2. Other objectives are to determine if there are differences between the patients considered candidates / not candidates for ALS and to analyze the functioning of the TC. Methods Retrospective observational study of all patients assessed by the AFUH TC. Results There were 19 meetings, in which 181 patients were evaluated, 65.4% male and with a mean age of 70.1 years. 31% had some degree of functional dependence, the Barthel median was 100 and Charlson 4. 58.5% were not considered a candidate for ALS at that time. The patients considered candidates to receive ALS were younger (72 vs 66; _p_ Conclusions The patients evaluated by the TC had a mean age of 70 years, high comorbidity and almost a third had some degree of functional dependence. More than half were not considered candidates for ALS at that time, these patients being older, with more comorbidity and a worse previous functional situation. TC decisions, based on objective clinical criteria, were almost always respected. Public institutions must get involved in triage procedures, which should and in our opinion must include the creation of TC in health centers. The implementation of Anticipated Decision programs (ADP) would help enable patients affected by triage decisions to participate in them. (shrink)

En este artículo se aborda la novela y el film de Georges Perec que llevan por título Un homme qui dort. Se establecen las conexiones filosóficas y literarias que la narración traza, la relación con el concepto de vida cotidiana tal como lo manejaron los Situacionistas o Henri Lefebvre, la búsqueda de la novela sin tema característica de la Modernidad y el concepto del formalismo ruso de extrañamiento como procedimiento de trascender y superar la experiencia instrumentalizada de la realidad.

El autor parte de la consideración de que el hilo conductor del cuerpo dispensa unidad a toda la combinación de fuerzas vivientes del individuo y de su entorno. Además, el sentimiento de estilo es una sensibilidad de carácter fisiológico que, a su vez, tiene que ver con el deseo de un cierto vagabundaje. La aspiración del arte es que suceda lo que en todo verdadero paseo: que nos devuelva al aprendizaje de la infancia, cuando las cosas se muestran por primera (...) vez, sin las presiones o perversiones que acarrean la rutina y la costumbre. Se trata de huir para producir lo real, para intensificar la experiencia de vida y la realidad. (shrink)

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)

The recruitment of respondents belonging to ethnic minorities poses important challenges in social and health research. This paper reflects on the enablers and barriers to recruitment that we encountered in our research work with persons belonging to ethnic minorities. Additionally, we applied the Matching Model of Recruitment, a theoretical framework concerning minority recruitment, to guide our reflection. We also explored its applicability as a research design tool. In assessing our research experience, we learned that minority recruitment in social and health (...) research is influenced by the social context of all key players involved in the research. Also, there are enablers and barriers within that social context facilitating or delaying the recruitment process. The main enablers to recruit respondents belonging to ethnic minorities include working with community agencies and gatekeepers who share a common vision with researchers and the latter’s ability to gain the trust of potential respondents. The main barriers include demanding too much from these same community agencies and gatekeepers and ignoring factors that could delay the completion of the research. Although we found the Matching Model of Recruitment to be an effective tool in assessing the processes of recruiting respondents belonging to ethnic minorities, further empirical research is needed to explore its usefulness during the research planning phase.

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.

ABSTRACT This paper discusses the respective contributions to development ethics made by Louis-Joseph Lebret (1897–1966) and his pupil and successor Denis Goulet (1931–2006). Sections 2 and 3 present steps in the emergence of a field of development ethics, and introduce the work of Lebret and Goulet, noting similarities and contrasts. Sections 4 and 5 clarify different senses and forms of ‘development ethics’, to then discuss who might be called ‘father of development ethics’. Lebret had devised a field of human economics (...) and in the 1950s called for an ethics of development, which he began to sketch. His work made significant advances, especially if development ethics is seen as an interdisciplinary policy-oriented field rather than as a subdiscipline in philosophical ethics. In the 1960s, Goulet went on to outline development ethics as a philosophical subdiscipline and to articulate various themes. In his later work though, while always speaking of a ‘discipline’ of development ethics but mostly meaning disciplined investigation, Goulet largely pursued, as had Lebret, a path toward a policy-oriented field of ‘practical ethics’, not a (sub)disciplinary path in a conventional academic sense.
