El objetivo de este estudio fue analizar la relación de diferentes comportamientos tácticos ofensivos con las conductas mostradas en los dos principales sistemas defensivos en balonmano. Para ello se realizó un análisis de coordenadas polares utilizando como conductas focales aquellas que identifican los principales sistemas defensivos y las acciones ofensivas con o sin transformaciones. Se observaron 538 situaciones correspondientes a 5 partidos de la primera división nacional española masculina con el software Hoisan utilizándose una herramienta diseñada ad hoc. El diseño observacional usado fue nomotético, puntual y seguimiento, siendo la unidad de observación la situación de defensa del equipo observado. Los resultados del análisis de la Calidad del Dato y Generalizabilidad muestran índices convincentes para los modelos utilizados. Los resultados del análisis de Coordenadas Polares muestran la mayor capacidad de oposición del sistema defensivo 5:1 al ataque. También destaca que la transformación atacante de 3:3 a 2:4 se usa más ante defensas abiertas y elicita el aumento de aparición de sanciones disciplinarias La herramienta observacional diseñada y la utilización de la técnica de coordenadas polares para la estimación de relaciones tácticas permite definir procedimientos de intervención que optimicen los recursos del entrenamiento y la competición en balonmano. The objective of this study was to analyze the relationship of different offensive tactical performances with the behaviours shown in the two main defensive systems in handball. For this, an analysis of polar coordinates was carried out using as focal behaviors those wich identify the main defensive systems and the offensive actions with or without transformations. There were 538 situations corresponding to 5 matches of the first Spanish national men's division with the Hoisan software by making use of an ad hoc tool. The observational design used was nomothetic, punctual and monitoring, the observation unit being the defense situation of the monitored team. The results of the Data Quality and Generalizability analysis show convincing rates for the models used. The results of the Polar Coordinates analysis show the greater oppositional capacity of the 5: 1 defensive system to attack. It also highlights that the attacking transformation from 3:3 to 2:4 is used more in the face of open defenses and it elicits an increase in the appearances of disciplinary sanctions. The observational tool designed and the use of the polar coordinate technique for the estimation of tactical relationships allows to define intervention procedures that optimize the resources of training and competition in handball.

El objetivo de este estudio fue analizar mediante el análisis de coordenadas polares la eficacia de las conductas que se muestran durante el juego combinativo ofensivo en el balonmano de élite masculino y femenino en España. Se observaron 10 equipos pertenecientes a la Liga ASOBAL en la categoría masculina y a la Copa La Reina en la femenina. Se utilizó una herramienta observacional ad hoc de 12 criterios y 62 categorías con un diseño observacional Nomotético/Puntual/Multidimensional. La unidad de análisis fue el ataque posicional. Se seleccionaron cuatro conductas focales: los medios tácticos colectivos simples, la combinación de los medios tácticos, las transformaciones y el lanzamiento ventajoso. Se realizó un análisis de coordenadas polares con el software HOISAN considerando significativos los módulos ≥1.96. Los resultados evidenciaron diferencias en el flujo de comportamientos entre el juego femenino y masculino. La categoría femenina con acentuadas acciones en la zona derecha del terreno. Los resultados más consistentes concuerdan con los primeros cuarenta minutos de juego y con la utilización de los medios tácticos colectivos simples y las combinaciones. En la categoría masculina se evidenció buen desempeño táctico durante todo el tiempo de juego. La combinación de los medios tácticos colectivos mostró una relación directa con el triunfo. En ambas categorías la transformación de los sistemas induce las finalizaciones en lanzamientos forzados. Las diferencias sugieren intervenir en la preparación de ambas categorías con una orientación específica hacia las mejoras en el desempeño del juego posicional combinativo. The aim of this study was analyse by means of polar coordinate analysis the efficacy of the behaviors shown during offensive combinative game in elite male and female handball in Spain. Ten teams belonging to the ASOBAL League were observed in the male category and to the Queen's Cup in the female category. An ad hoc observational tool of 12 criteria and 62 categories with a Nomothetic/Punctual/Multidimensional observational design was used. The unit of analysis was the positional attack. Four focal behaviours were selected: simple collective tactical means, combination of tactical means, transformations and advantageous launchs. An analysis of polar coordinates was carried out with the HOISAN software, considering the modules ≥1.96 to be significant. The results showed differences in the flow of behaviors between the male and female game. The female category with accentuated actions in the right zone of the field. The most consistent results coincide with the first forty minutes of play and with the use of simple collective tactical means and combinations. In the male category, good tactical performance was evident throughout the game. The combination of the collective tactical means showed a direct relation with the victory. In both categories the transformation of the systems induces the completions in forced launchs. The differences suggest to intervene in the preparation of both categories with a specific orientation towards the improvements in the performance the combinative positional game.

AbstractPreservation of the facial nerve is crucial in any type of facial procedure. This is even more important when performing plastic surgery on the face. An intricate knowledge of the course of the facial nerve is a requisite prior to performing facelifts, regardless of the technique used. The complex relationship of the ligaments and the facial nerve may put the nerve at an increased risk of damage, especially if its anatomy is not fully understood. There are several danger zones during dissection where the nerve is more likely to be injured. These include the areas where the nerve branches become more superficial in the dissection plane, and where they traverse between the retaining ligaments of the face. Addressing these ligaments is crucial, as they prevent the transmission of traction during facelifts. Without sufficient release, a satisfying pull on the soft tissues may be limited. Traditional superficial musculoaponeurotic system techniques such as plication or imbrication do not include surgical release of these attachments. Extended facelift techniques include additional dissection to release the retaining ligaments to obtain a more balanced and healthier look. However, these techniques are often the subject of much debate due to the extended dissection that carries a higher risk of nerve complications. In this article we aim to present the relationship of both the nerve and ligaments with an emphasis on the exact location of these structures, both in regard to one another and to their locations within the facial soft tissues, to perform extended techniques safely.

AbstractThe aims of this paper are to identify three barriers to the development of cognitive approaches to the study of religion and to suggest how each might be circumvented. The first of these barriers is methodological and lurks amid two issues that, historically, have dominated anthropologists' reflections on the relationship of their discipline to psychology. The older of the two can be characterized as the "psychic unity" controversy (see Shore 1995). The second issue is the controversy over the "autonomy of culture". Advocates of the latter thesis are usually unsympathetic to psychological explanations of religious phenomena. In the first section, I shall begin by briefly examining each of those issues and then exploring the connections between the two as well as interesting logical tensions that arise in the face of popular responses to each. In section two, I shall consider a pair of barriers to a cognitive psychology of religion rooted in two strategies that have dominated many psychologists' approaches to the study of religion. I will argue that for some purposes, at least, both strategies should be relaxed. Finally, in section three, I shall briefly sketch one sort of cognitive approach to religious phenomena, suggesting how it handles the two strategic barriers in particular.

The books of the Apocrypha contain extensive reflection on the theologies of earlier Jewish writings, particularly in regard to election, the Torah, and the Deuteronomistic theology of history, in the face of several critical situations facing the Jewish people (the advance and advantages of Hellenization, the repression of Judaism under Antiochus IV, ongoing life as a minority culture throughout the Diaspora, and domination and devastation under Rome). They also bear witness to important developments both in personal and national eschatology and in the identification of supernatural forces impacting human existence (e.g., angels and demons). Early Christians, in turn, found these texts to provide important resources for their reflection upon the person and work of Jesus, applying developments within the Wisdom tradition in their delineation of the relationship of the Son to God and within the Jewish martyrological traditions to their professions about the atoning force of Jesus’ death. These texts thus exercised an important influence on the theologies articulated in the New Testament and the development of the doctrines and creeds embraced by the universal church, despite the ongoing discussions within the church concerning their canonical status.

The interactions of a Spanish football team of the Second A (10 official games) are analyzed, evaluating possible behavioral patterns that appear in a regular way in high level football. Observational methodology was used, by Polar Coordinates Analysis, to discover and evaluate the relationships generated between a considered focal behavior and the different conditioned categories, describing behavioral masses among the players. The matches were observed and recorded with an ad hoc observation instrument. The relations of dual character between the players taken as (focal behaviors) right midfielder and forward and the other players (conditioned conducts) were analyzed. The results show differences in the relationship established based on the outcome of the match. Matches that end with a favorable result, the right midfielder takes center stage, as a node of intermediation between the right centre back, left center back, left midfielder, and second striker. In these, the forward is clear receiver in the actions of completion. With the result of the unfavorable match, the connection networks change, generating a network of reciprocal interaction wider and different between the aforementioned player, right midfielder and the rest of the components, with special relation in the players that occupy the right back, left back, right centre back, right winger, left winger, second striker and forward. In these games the striker acquires a role of greater collaboration in the creation in offensive phases, participating as a node in the game network with intermediation functions.

AbstractAstrology is a neglected cultural form in the study of South Asian society. It is also one which pays attention to the individual in ways that seem to fly in the face of scholarly understandings of Asian societies as places where individuality has little importance. The ideology of caste, the institution most often taken as an analytical entry to South Asian societies, gathers people into groups on the basis of their gross similarities and fixes a person's condition for life. Astrology treats individuals as distinguished by subtle differences and liable to momentary changes. The paper argues that caste ideology and astrology have a common vocabulary and logic, one which is genealogical and combinatory, and suggests in turn several conclusions about the relationship of individuals and society in South Asian cultures.

Background During the Covid-19 pandemic, the negative effects of wearing a mouth-nose cover (MNC) on interpersonal functioning have been discussed in public media but empirical studies on how wearing MNCs affect social judgements are sparse. In the present study, we investigated the effects of MNCs on trustworthiness appraisals, the influence of changes due to MNCs in evaluating joy, and the relationship between a social-cognitive appraisal bias and a participant’s characteristics. Methods All participants (N = 165) judged the intensity of happiness and trustworthiness in calm facial stimuli presented with and without a surgical mask covering part of the face. We analysed the relationship of changes in judgements evoked by MNCs to participants’ evaluations of MNCs as protective tools and explored their associations with the burden experienced by wearing MNCs, compliance to behaviour recommendations, their risk associated with the pandemic, and their levels of psychological distress. Results Overall, calm facial stimuli covered with MNCs were evaluated as less trustworthy and, to an even stronger extent, less happy than uncovered facial stimuli. However, participants varied in whether they showed a negative or positive evaluation of faces with MNCs; the negative bias was stronger in those participants who attributed lower protective potential to MNCs, experienced a higher burden while wearing MNCs, wore MNCs less often, and experienced a higher level of psychological distress. Conclusions A negative bias in trustworthiness appraisals of faces with a positive emotional expression covered by MNCs is linked to a participant’s evaluation of MNCs as inefficient and burdening and their experience of high psychological distress.

According to the decisions of international scientific forums, the problem of phenomenon of rosacea (acne rosacea), a common dermatosis with numerous unexplained aspects of etiopathogenesis is a promising area of modern medical research. The aim of the study was theoretical substantiation of the essential features of the mechanisms of occurrence, development and clinical manifestations of the first signs of rosacea in women of reproductive age. The use of a systematic analytical methodical approach to assess the data of clinical and laboratory examinations of women with rosacea, conducted in different regions of the world, allowed to establish the originality of such manifestations of dermatosis as the appearance of unexpected rushes to limited areas of the face, accompanied by local redness and local heat areas of the skin differring significantly from similar rushes in other diseases or syndromes (menopause, migraine, etc.). It is established that the peculiarity of the relationship of these clinical characteristics (from English: rush, ruddy, redness, rosacea, reproductive age of women, reaction) allows to indicate the first signs of dermatosis as a phenomenon inherent in this disease Rush-Ruddy-Rosacea-Reproduce-Reaction (abbreviated – «5-R»), the key pathophysiological target of which (as well as the disease as a whole) is a disorder of a set of hierarchically dependent mechanisms of the evolutionarily determined motivational need to ensure reproductive function in women (both at the cellular level and extracellular structures of the ovaries, and at different levels of subcortical formations and centers of the cortex of the cerebral hemispheres). The phenomenon of rosacea rush is closely related to other phenomena of this dermatosis – hypersensitivity of bradykinin receptors, actinic elastosis, development of post erythematous telangiectasia. The prospect of further research on the problem of rosacea is to study the relationship of disorders in the functional systems of molecules of signaling compounds of different classes (hormones, eicosanoids, neuropeptides, kinins, cytokines and others) in the pathogenesis of the disease.
