Purpose: This systematic review aimed to analyze the impact that the COVID-19 lockdown had on the amount of physical activity performed by university students.Materials and Methods: A systematic electronic search for studies providing information regarding physical activity levels pre and during COVID-19 pandemic in university students was performed up to 20th October 2020 in the databases Cochrane Library, PubMed, SPORTDiscus, and Web of Science. The risk of bias of external validity quality of included studies was assessed by means of those (...) the Newcastle-Ottawa Scale. The quality of the evidence for main outcomes was graded using the Grading of Recommendations Assessment, Development and Evaluation approach.Results and Conclusions: A total of 10 studies were selected. Physical activity levels were assessed by means of questionnaires and accelerometer. Risk of bias was regarded as low and high in six and four investigations, respectively. The quality of evidence was downgraded to low. A significant reduction of physical activity levels were observed in 9 studies. Compared to pre-lockdown values, five studies showed a reduction of light/mild physical activity between 32.5 and 365.5%, while seven studies revealed a reduction of high/vigorous physical activity between 2.9 and 52.8%. Walking, moderate, vigorous, and total physical activity levels have been reduced during the COVID-19 pandemic confinements in university students of different countries. Despite of the reductions, those who met the current minimum PA recommendations before the lockdown generally met the recommendations also during the confinements. (shrink)

La ética ambiental, últimamente se ha visto consultada y retomada, gracias a las diferentes situaciones problemáticas respecto a los ecosistemas y a los cambios que se han dado alrededor del planeta, ya que es recurrente que cada vez sean más y frecuentes, los cambios climáticos y fenómenos naturales que antes no se daban en determinados territorios.Gran parte de las problemáticas tienen que ver con las labores que realizamos los seres humanos, si no es que toda la responsabilidad recae en nosotros, (...) con ello nos referimos a que todo el desequilibrio climático que se tiene hoy en día, es causa de la poca estima que tenemos respecto con el ambiente, la contaminación de suelo, agua y aire; que si bien se nos enseña a separar la basura de nada sirve si al final se reúne toda en los deshechos o rellenos, por otra parte la poca autorreflexión de los seres humanos en cuanto a ello, así como el daño que ello les provoca a las especies de todo tipo, llevándolas al peligro, y por último a la extinción, empero no sólo las especies animales se ven afectadas, sino también la flora de los ecosistemas va desapareciendo con la invasión del ser humano y el poco respeto a la naturaleza, cada vez las sociedades crecen más y con ello, por ende, el crecimiento de la ciudad o mancha urbana.Todo lo anterior nos remite a que se piense desde un ámbito ético, es decir, nuestra relación con el medio ambiente, por lo que nuestro objetivo es plantear las principales problemáticas acerca del tema y de la ética ambiental desde una perspectiva filosófica que, si bien ya es parte, de todo esto, nos cuestionamos: ¿qué se puede hacer respecto a la contaminación?, ¿qué se debería cambiar? ¿para qué? ¿a dónde llegar? ¿cómo lograrlo? es por ello que se tomará en cuenta el trabajo de los filósofos desde una perspectiva de la ética, para poder proponer soluciones o tratar de detener las problemáticas, para causar cambios de algunos hábitos a partir de la reflexión del individuo, es cierto que cada individuo; tiene una rutina e inconscientemente se vuelve parte de la contaminación, de todas las acciones que ejecutamos en el día usamos diferentes instrumentos que provienen de la naturaleza, y es obvio que no se puede llegar a ser un ermitaño, del bosque o del campo, estando acostumbrado a las comodidades de la ciudad, lo que se busca aquí es la reflexión de las actividades que desempeñamos todos los día y poder cambiarlas o si es posible frenarlas de algún modo (si no es necesaria la actividad dentro de la vida), para ser más amigables y responsables del planeta, ya que es éste el fin de la ética ambiental: ponerla en práctica, aplicar las teorías que sean benefactoras del medio ambiente.

Lower extremity non-contact soft tissue injuries are prevalent in elite futsal. The purpose of this study was to develop robust screening models based on pre-season measures obtained from questionnaires and field-based tests to prospectively predict LE-ST injuries after having applied a range of supervised Machine Learning techniques. One hundred and thirty-nine elite futsal players underwent a pre-season screening evaluation that included individual characteristics; measures related to sleep quality, athlete burnout, psychological characteristics related to sport performance and self-reported perception of chronic (...) ankle instability. A number of neuromuscular performance measures obtained through three field-based tests [isometric hip strength, dynamic postural control and lower extremity joints range of motion ] were also recorded. Injury incidence was monitored over one competitive season. There were 25 LE-ST injuries. Only those groups of measures from two of the field-based tests, as independent data sets, were able to build robust models [area under the receiver operating characteristic curve score ≥0.7] to identify elite futsal players at risk of sustaining a LE-ST injury. Unlike the measures obtained from the five questionnaires selected, the neuromuscular performance measures did build robust prediction models. The inclusion in the same data set of the measures recorded from all the questionnaires and field-based tests did not result in models with significantly higher performance scores. The model generated by the UnderBagging technique with a cost-sensitive SMO as the base classifier and using only four ROM measures reported the best prediction performance scores. The models developed might help coaches, physical trainers and medical practitioners in the decision-making process for injury prevention in futsal. (shrink)

Study of Islamic philosophy of Yaḥyá ibn Ḥabash Suhrawardī, 1152 or 1153-1191.

In this paper we discuss the meaning of Owen's coalitional extension of the Banzhaf index in the context of voting situations. It is discussed the possibility of accommodating this index within the following model: in order to evaluate the likelihood of a voter to be crucial in making a decision by means of a voting rule a second input (apart from the rule itself) is necessary: an estimate of the probability of different vote configurations. It is shown how Owen's coalitional (...) extension can be seen as three different normative variations of this model. (shrink)

This paper connects two notions: Hart and Mas-Colell’s ‘potential’, related to the value of coalitional games, and Coleman’s earlier notion of ‘power of a collectivity to act’, related to the easiness to make decisions by means of a voting rule.

Explorées depuis 1924, les fortifications de l’oppidum de Saint‑Blaise dans le Sud de la France ont récemment fait l’objet de nouvelles investigations à l’occasion de la mise en valeur projetée du site.S’ils ont confirmé l’empilement et/ou la succession d’au moins quatre lignes de défense appartenant aux périodes gauloise, tardo-antique et médiévale, ces travaux ont beaucoup renouvelé notre connaissance et notre interprétation de ces murailles, en particulier pour la période protohistorique. Deux points principaux doivent être relevés : l’existence d’un puissant mur (...) gaulois dès la fin du viie s. av. J.‑C., qui nous permet d’identifier ici la forteresse de la tribu gauloise des Ségobriges que les Phocéens ont abordé avant la fondation de Marseille ; la muraille hellénistique en grand appareil de type grec doit désormais être interprétée comme un ouvrage gaulois inachevé, anéanti par les Romains lors de la chute de l’oppidum à la fin du iie s. av.

Esports have transformed playing video games into a competitive activity that bears similarities to sports and the processes of sportization. Taking as a starting point the concept of sports as competitive games, the objective of this work is to analyse the sportization of esports, as well as the impact of esports on the concept of sports and their implications on sports in the immediate future. Sports and esports are two different realities that interact with each other. This is a conceptual (...) problem for sports, and it also defines a practical challenge in the immediate future of sports. The virtual environment offers new possibilities in sports, such as broadening the possibilities of confrontation and competition development, contributing to reducing the environmental impact of certain sports, improving safety and maintaining the physical integrity of athletes, and increasing social justice and equality of chances in sports competitions. The challenge, therefore, is to try to bring esports and sports closer together, even moving toward hybrid sports, as addressed throughout this article. (shrink)

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)

Objective:To describe the professional values of the nurse lectures according to 241 nursing students, who participated voluntarily, in three different universities of Bogotá.Methodology:This is a quantitative, descriptive cross-sectional study that applied the Nurses Professional Values Scale—permission secured—Spanish; three dimensions of values were applied: ethics, commitment, and professional knowledge.Ethical consideration:Project had ethical review and approval from an ethics committee and participants were given information sheets to read before they agreed to participate in the project.Findings:It was concluded that nursing students, in general, (...) do perceive these values in their professors, and they give priority to the dimension of ethics, followed by the knowledge dimension, and finally, commitment.Discussion:It is evident that professional values are transmitted by professors and students place importance to such values. Values related to the other’s care are paramount in nursing training in Colombia as well as in other countries.Conclusion:It was found that participating students observed professors directly in relation to values focused on direct patient care, respect for privacy, respect for life, while matters related to professional improvement, participation in unions were not actually analyzed may be due to poor promotion activities and unions during undergraduate studies. The results obtained are primary approach to the study of values related to nursing, a topic which needs to be researched, something vital to all the country offering nursing training programs.

This study is defined within the context of the critical posthuman project of decentring humanist subjectivity. We argue that because agential realism, and the agency and performativity that go with it, do not enable non-human matter to be accountable, only human matter, in its intra-active becoming with non-human matter, can support an ethical project. Secondly, we map our understanding of Barad’s agential realism, explaining the importance of agential cuts in phenomena-in-their-becoming that are the world worlding itself, and evaluate ethics, agency, (...) and performativity in this material-discursive framework. Thirdly, understanding the material-discursive to underpin storied matter, we engage it via some clarification of narrative, and narrative agency. We conclude that much organic or inorganic nature as non-human matter is directional and responsive, so alive and generative and, in this sense, capable of worlding itself. However, it does not tell its own stories in the process. (shrink)

In recent years, preimplantation genetic testing (PGT) of IVF embryos have gained much traction in clinical assisted reproduction for preventing various genetic defects, including Down syndrome. However, such genetic tests inevitably reveal the sex of IVF embryos by identifying the sex (X and Y) chromosomes. In many countries with less stringent IVF regulations, information on the sex of embryos that are tested to be genetically normal is readily shared with patients. This would thus present Muslim patients with unintended opportunities for (...) sex selection based on personal or social biases without any pressing need or valid medical reason. Additionally, there are other patients who claim using PGT for preventing genetic defects as a pretext or “convenient excuse,” with a secret intention to do sex selection when it is banned in their home country. Currently, non-medical sex selection is a highly-controversial and hotly debated issue in Islam, because there is generally a strong preference for having sons over daughters due to widespread cultural norms of elderly parents depending on their sons for financial support, as well as the need for male heirs to continue the family lineage within the backdrop of local patriarchal cultures. There is a risk of gender imbalance and social disequilibrium occurring in Islamic societies due to prevalent sex selection. Hence, the question is whether opportunistic sex selection with PGT would contravene Islamic ethics and principles, which will thus be discussed here. (shrink)

Le XIIe siecle, celui des renaissances, est une periode d'echanges multiformes entre traditions, cultures, ecoles. Sans doute aucun siecle n'est-il plus difficile a unifier que celui-ci: l'appropriation des doctrines greco-arabes voisine avec le developpement autonome des arts du langage, le temps d'Abelard est aussi celui de Bernard de Clairvaux, la dialectique s'elabore dans l'affrontement des multiples ecoles ou sectes.

Despite the abundant production of catecismos in 16th century Spain, few of them were addressed directly to the new converted population, and fewer still were translated into or written in Arabic. Given the dimension of the Morisco question within Catholicism at the time, this scarcity is striking. Archbishop of Valencia and attending member of the Council of Trent, Martín Pérez de Ayala, commissioned one of these rare texts, the Doctrina Christiana en Lengua Arauiga y Castellana, written in Valencian Arabic. The (...) text encloses a brief catechism containing mainly prayers but also a set of instructions about both Arabic phonetics and doctrinal matters. The present article intends to study the language ideology present in the translation of Christian doctrine into Arabic. In order to do so, it asks questions such as whether the emphasis on spoken Arabic is a conscious distance from a Koranic Arabic language, and how religious space is shaped through language.

Fascinating and well-documented in its details of cultural migration and evolution, this book offers a well-balanced perspective on the mutual influence of Arabic and Western worlds during the Middle Ages. It traces the transmission of Greek philosophy and science to the Islamic world, forming a portrait of medieval Muslim thought that illustrates its commonalities with Judaic and Christian teachings as well as its points of divergence. He shows how a particular type of Hellenistic culture made its way through the Syrian (...) Church, the Zoroastrians of Persia, and the pagans of Harran to the Islamic community, attaining its final metamorphosis in northeast Italy, where it constituted an anti-ecclesiastical influence that helped to pave the way for the Renaissance.

Arab researchers encounter formidable obstacles when conducting and publishing their scientific work. We conducted semi-structured interviews with 17 Arab researchers from various Arab Middle East countries to gain a comprehensive understanding of the difficulties they face in research and publication. We analyzed the transcripts using reflexive thematic analysis. Our findings revealed several key challenges. First, Arab researchers struggle to conduct high-quality research due to limited resources, inadequate funding, and a lack of a supportive research infrastructure. Furthermore, a shortage of teamwork (...) and mentoring diminishes research productivity. Perverse promotion policies, heavy teaching loads, and low salaries force many researchers to seek external income sources, leaving them with insufficient time for research. Regarding publishing in high-impact journals, Arab researchers confront challenges existing of insufficient scientific writing skills, underrepresentation on editorial boards, and unconscious biases against researchers from economically challenged areas. Finally, achieving research integrity is closely tied to lack of access to essential resources. To address these issues, our participants proposed targeted interventions at the institutional and external levels. For example, universities can implement mentoring programs, offer workshops on scientific writing and publishing, and foster a supportive institutional culture for research. Addressing the underrepresentation of Arabic researchers on editorial boards is crucial for equity in global scientific publishing. In conclusion, acknowledging and addressing these challenges will empower Arab researchers, elevate research quality, and promote equitable global scientific collaboration. Our findings provide guidance for universities, governments, and international donors seeking to enhance research and publication practices in the Arab Middle East. (shrink)

Medieval Arabic algebra is a good example of an artificial language.Yet despite its abstract, formal structure, its utility was restricted to problem solving. Geometry was the branch of mathematics used for expressing theories. While algebra was an art concerned with finding specific unknown numbers, geometry dealtwith generalmagnitudes.Algebra did possess the generosity needed to raise it to a more theoretical level—in the ninth century Abū Kāmil reinterpreted the algebraic unknown “thing” to prove a general result. But mathematicians had no motive to (...) rework their theories in algebraic form. Because it offered no advantage over geometry, algebra remained a practical art in both the Islamic world and in Europe until the scientific uphevals of the 17th–18th centuries. (shrink)

This monograph explores the logical systems of early logicians in the Arabic tradition from a theoretical perspective, providing a complete panorama of early Arabic logic and centering it within an expansive historical context. By thoroughly examining the writings of the first Arabic logicians, al-Fārābī, Avicenna and Averroes, the author analyzes their respective theories, discusses their relationship to the syllogistics of Aristotle and his followers, and measures their influence on later logical systems. Beginning with an introduction to the writings of the (...) most prominent Arabic logicians, the author scrutinizes these works to determine their categorical logic, as well as their modal and hypothetical logics. Where most other studies written on this subject focus on the Arabic logicians’ epistemology, metaphysics, and theology, this volume takes a unique approach by focusing on the actual technical aspects and features of their logics. The author then moves on to examine the original texts as closely as possible and employs the symbolism of modern propositional, predicate, and modal logics, rendering the arguments of each logician clearly and precisely while clarifying the theories themselves in order to determine the differences between the Arabic logicians’ systems and those of Aristotle. By providing a detailed examination of theories that are still not very well-known in Western countries, the author is able to assess the improvements that can be found in the Arabic writings, and to situate Arabic logic within the breadth of the history of logic. This unique study will appeal mainly to historians of logic, logicians, and philosophers who seek a better understanding of the Arabic tradition. It also will be of interest to modern logicians who wish to delve into the historical aspects and progression of their discipline. Furthermore, this book will serve as a valuable resource for graduate students who wish to complement their general knowledge of Arabic culture, logic, and sciences. (shrink)

Research in communication studies has suggested that Al-Jazeera produces different versions of news stories for different audiences. Yet, examining the linguistic means used to create these versions has remained under-researched. Drawing on Fairclough’s three-dimensional model (1992) and Halliday’s Transitivity Model (1985), this study aims at exploring how Al-Jazeera Arabic (AJA) and Al-Jazeera English (AJE) discursively represented the participants involved in the 2022 Russo-Ukrainian conflict in headlines. The analysis of transitivity patterns in AJA and AJE headlines reveals both similar and different (...) representations of the conflict. Although they avoided negative labeling of the Russian government, both channels ascribed conflict escalation to it, highlighting civilians suffering and protesting. Nevertheless, while AJE emphasized the Ukrainian government vulnerability, AJA presented the conflict as a confrontation between two symmetrical forces. Similarities are attributed to organizational and social institutional forces, while differences result from different editorial policies and audience preferences. As discursive and social practices, the headlines contribute to shaping audience perceptions of the conflict, with AJA challenging the prevailing western narrative of the conflict while AJE reinforcing it.

Où en est l'étude de la philosophie arabe? Ce livre propose un état des lieux. Il s'agit de dresser un premier bilan des travaux menés dans ce vaste champ. On examine l'historiographie, les dénominations employées; on s'interroge sur les thématiques, les objets retenus et les méthodes d'analyse mises en oeuvre ; on y présente aussi des études sur des auteurs, des traditions ou des concepts, qui montrent comment le travail progresse, quelles tensions perdurent, quelles sont les perspectives."--Page 4 of cover.

[fr] Dans les Ḫaṣā’iṣ, Ibn Ǧinnī (m. 392/1002) fait état, incidemment, d’une différenciation entre parlers arabes nomades et sédentaires, ces derniers étant caractérisés par une perte partielle de la flexion désinentielle (’i‘rāb). Dans la mesure où Ibn Ǧinnī se réfère sur ce point à une source antérieure de près de deux siècles d’une part, indique qu’il n’y a presque plus, à son époque, de bédouin au parler « châtié » (faṣīḥ, c’est-à-dire fléchi mu‘rab) d’autre part, on peut voir dans ses (...) remarques une reconnaissance implicite d’une situation de diglossie, les parlers nomades étant à l’origine de la variété haute (al-luġa al-‘arabiyya al-faṣīḥa). Cette situation est d’ailleurs révélée par une anecdote, où l’on voit un même usager, d’origine bédouine, alterner ce qu’Ibn Ǧinnī appelle « les deux manières de parler » (ǧihatā al-kalām), avec et sans flexion désinentielle. Malgré les apparences, il ne s’agit pas de sociolinguistique et d’histoire de la langue. Il s’agit de théorie du langage, avec l’hypothèse d’un phénomène d’entropie, liée à l’utilisation de la langue, l’utilisateur se passant, par d’autres moyens, de la flexion désinentielle, source de difficulté et d’erreurs. Il s’agit aussi et surtout d’un discours épilinguistique, conforme à l’idéologie linguistique (thèse de la faṣāḥa bédouine) et à la théologie (thèse de la « langue du Ḥiǧāz » comme al-luġa alfuṣḥā), deux thèses difficilement conciliables.
