Introduction/purpose: The paper presents the method of applying multicriteria decision-making methods in order to improve shooting and select the most favorable conditions for shooting. Alternatives were ranked by individual multi-criteria decision-making methods AHP and VIKOR by experts, and then the most favorable alternative was selected using the Borda method of group decision making. The aim of the work is to select the most efficient way of shooting with minimal human fatigue, consumption of movable things and in the shortest possible time through a combination of multi-criteria decision-making methods, which will ensure the accuracy and precision of the rifle for subsequent shooting and other operations. Methods: The paper presents one of the ways of using multidisciplinary methods of multi-criteria decision making for a specific problem in the field of tactics with weapon systems. Experts from the field of armaments, using the AHP and VIKOR methods of individual multi-criteria decision making, selected the most favorable alternative in accordance with four given criteria. Then, by applying the Borda method of group decision making, the the most favorable alternative was selected - the most favorable conditions for the execution of preparatory shooting at serial number one with a 12.7 mm long range rifle. The alternatives are four shootings, namely, two ways of performing preparatory shooting with a 12.7 mm long range rifle at serial number one, one from the current Instructions and Program of Shooting with Infantry Weapons and the other newly proposed method, as well as two ways of realizing shooting for testing the accuracy and precision of a long range rifle. Results: The selection of the most effective conditions for the execution of the first initial preparatory shooting at serial number one with a long range rifle, which will ensure maximum accuracy of the weapon and the minimum consumption of resources - time, ammunition, targets, and personnel fatigue. Conclusion: The solution takes into account the simultaneous optimization of several criteria in order to select the most efficient way of performing preparatory shooting at serial number one in order to ensure rested and trained personnel as well as accurate and precise long range rifles for subsequent shootings, which leads to the maximum saving of resources, the satisfaction of personnel, and precise weapons.

O propósito deste trabalho foi verificar o impacto vertical provocado pelo recuo com arma de fogo curta nas articulações do punho, cotovelo, e ombro, a partir da adoção de posições de tiro diferenciadas. O sujeito da pesquisa foi um atirador com 22 anos de experiência. O instrumento utilizado para a mensuração foi um acelerômetro piezoelétrico triaxial do tipo 4321, da Brüel e Kjaer, conectado a um sistema de aquisição de dados. Foi utilizada uma pistola de ação simples Imbel, calibre 380 ACP e cano quatro polegadas, com munição recarregada. As três posições de tiro foram Weaver, Weaver Chapman e Isósceles. Os resultados mostraram que, no punho, a maior absorção ocorreu na posição Weaver Chapman, apresentando diferenças significativas em relação às demais; no cotovelo e no ombro, a Weaver apresentou os menores valores em relação às demais.

Proponemos una nueva interpretación del pasaje de Justino (44.5) relativo al dominio cartaginés en la Península Ibérica, que no se iniciaría con la fundación de Gadir, sino de una colonia por parte de los gaditanos con la participación del templo de Melqart de Tiro. Identificamos esa colonia con Carteia, fundada en el segundo cuarto del siglo iv a.C. con la intervención del Melqart tirio en calidad de archegetes. Este episodio permite una comprensión más completa de las relaciones en el seno de la koiné identitaria tiria, una red de comunidades que reconocen, en Tiro a su madre patria y se vinculan por lazos de parentesco a través de la figura de Melqart. La intervención militar cartaginesa en auxilio de Gadir, a mediados del siglo IV a.C., se explicaría en el seno de esa red y confirmaría el establecimiento por parte de Cartago de ciertas bases territoriales en la Península antes de los Bárquidas, lo que invita a datar en la segunda mitad del siglo IV a.C. exploraciones atlánticas como las de Hannón e Himilcón.

La administración de feedback dirigido al movimiento para conseguir una ejecución correcta y mejorar la efectividad de los gestos técnicos es una práctica común entre los entrenadores de baloncesto. Sin embargo, durante la última década se ha cuestionado su efectividad en determinadas situaciones y se relativizado el interés de su aplicación. Nuestro objetivo es comparar la efectividad del tiro de media distancia en jugadores de baloncesto en dos situaciones distintas: sin instrucciones ni feedback técnico (A) y con instrucciones técnicas y feedback externo sobre la ejecución del movimiento (B). Han participado en el estudio 8 jugadores de categoría cadete de máximo nivel estatal. Los resultados muestran que la efectividad (por días, series y tiros lanzados) es mayor en la situación A que en la B (p < 0,05, p < 0,05 y p < 0,01, respectivamente). Se concluye que se consiguió mayor porcentaje de aciertos en la intervención con feedback externo basado sólo en el resultado de la acción que en la guiada además por instrucciones y feedback técnico. Los resultados obtenidos cuestionan la efectividad de la administración de feedback técnico relacionado con un modelo ideal de lanzamiento.

Una de las especies que mayores controversias ha suscitado desde su proceso de domesticación hasta el comienzo de los variados usos a los que ha sido sometida es el caballo. Sin ánimos de exponer más allá de una breve síntesis alguno de los debates en curso, tratamos las principales evidencias directas e indirectas que han servido para abordar su proceso de domesticación y las dificultades a las que se enfrenta la Arqueozoología en el estudio de las limitadas muestras óseas del registro arqueológico, especialmente en las etapas de la Prehistoria más reciente. Aunque la funcionalidad de esta especie resulta en muchos contextos problemática se confirma en algunos casos como un recurso alimentario de primer orden, además de su empleo como animal de tiro, monta y carga. En menor medida, el caballo también está vinculado a depósitos relacionados con el mundo funerario y simbólico, cuyas exiguas evidencias directas contrastan con el rico patrimonio arqueológico y su sobrerrepresentación literaria de las etapas prerromanas.

The purpose of this paper is to describe athletes' cognitive-emotional processes during competitions through an idiographic and ecologically valid study method based on verbal protocols and event sequential analyses. A world-class marksman and regional-level marksman filled in an affect grid after each shot during several competitions. Verbal reports were collected after each set by a delayed retrospective recall method and compared according to perceived performance periods. Event sequential analyses were conducted. The results showed distinct interpersonal patterns of affective states fluctuations and self-regulation strategies. Furthermore, intrapersonal patterns as a function of perceived performance were also identified. We suggest that the proposed methods are useful in studying athletes' cognitive-emotional processes during ongoing competitions, as they ensure high ecological validity and provide in-depth information for more effective, individually-tailored interventions.
