A fase contemporânea do desenvolvimento do esporte tem certas características que influenciam muito a organização da preparação e treinamento dos atletas, determinando novas tarefas e exigências mais ...complexas para o treinador. O objetivo do presente trabalho era projetar uma alternativa metodológica para a melhoria do pensamento tático no Tashi Waza em atletas de judô, categoria 15-16 anos, do Eide de Pinar del Río. Foram apresentadas as características mais importantes da estratégia e das táticas de judô, bem como os princípios essenciais que as sustentam. Além disso, foi apontada a conveniência de utilizar formulários auxiliares na preparação e no treinamento técnico-táctico do judô. O estudo continuou com uma análise leve aplicada ao judô como uma variável relevante no desenvolvimento do pensamento tático. Foi dada ênfase aos diferentes tipos de táticas no combate ao judô, bem como aos processos psicomotores em cada uma das fases do combate, tudo isso levando em conta as particularidades dos atletas desta época. Os métodos científicos empíricos utilizados foram a observação e entrevista, e métodos teóricos como a análise e síntese histórico-lógica, que ofereceram mais rigor à pesquisa. A idéia de investigar o pensamento tático no judô surgiu há alguns anos, em resposta à questão de ensinar os atletas a encontrar suas próprias soluções para os inúmeros problemas que surgem no combate.

The contemporary stage of sport development has certain characteristics that exert a great influence on the organization of the preparation and training of athletes, determining for the coach new tasks and more complex demands. The present work had as objective to design a methodological alternative for the improvement of tactical thinking to Tashi Waza in judo athletes, category 15-16 years old, of the Initial Sport School (Eide in Spanish) of Pinar del Rio. To get into the subject, the most important characteristics of judo strategy and tactics were outlined, as well as the essential principles that support them. In addition, the convenience of using auxiliary forms in the technical-tactical preparation and training of the judo athletes was pointed out. The study continued with a light analysis applied to judo as a relevant variable in the development of tactical thinking. Emphasis was placed on the different types of tactics in judo combat, as well as on the psychomotor processes in each of the phases of combat, all this taking into account the particularities of athletes at these ages. The empirical scientific methods used were observation and interview, and the theoretical ones were historical-logical and synthesis analysis, which offered greater rigor to the research. The idea of investigating the tactical thinking in judo arose a few years ago, in response to the question of teaching athletes to solve by themselves the innumerable problems that arise in combat.

Based on ethnographic observations and interviews with prisoners, correctional officers, and civilian staff conducted in solitary confinement units, Way Down in the Hole explores the myriad ways in ...which daily, intimate interactions between those locked up twenty-four hours a day and the correctional officers charged with their care, custody, and control produce and reproduce hegemonic racial ideologies. Smith and Hattery explore the outcome of building prisons in rural, economically depressed communities, staffing them with white people who live in and around these communities, filling them with Black and brown bodies from urban areas and then designing the structure of solitary confinement units such that the most private, intimate daily bodily functions take place in very public ways. Under these conditions, it shouldn’t be surprising, but is rarely considered, that such daily interactions produce and reproduce white racial resentment among many correctional officers and fuel the racialized tensions that prisoners often describe as the worst forms of dehumanization. Way Down in the Hole concludes with recommendations for reducing the use of solitary confinement, reforming its use in a limited context, and most importantly, creating an environment in which prisoners and staff co-exist in ways that recognize their individual humanity and reduce rather than reproduce racial antagonisms and racial resentment.

In Dying to Learn, Michael Hunzeker develops a novel theory to explain how wartime militaries learn. He focuses on the Western Front, which witnessed three great-power armies struggle to cope with ...deadlock throughout the First World War, as the British, French, and German armies all pursued the same solutions-assault tactics, combined arms, and elastic defense in depth. By the end of the war, only the German army managed to develop and implement a set of revolutionary offensive, defensive, and combined arms doctrines that in hindsight represented the best way to fight. Hunzeker identifies three organizational variables that determine how fighting militaries generate new ideas, distinguish good ones from bad ones, and implement the best of them across the entire organization. These factors are: the degree to which leadership delegates authority on the battlefield; how effectively the organization retains control over soldier and officer training; and whether or not the military possesses an independent doctrinal assessment mechanism. Through careful study of the British, French, and German experiences in the First World War, Dying to Learn provides a model that shows how a resolute focus on analysis, command, and training can help prepare modern militaries for adapting amidst high-intensity warfare in an age of revolutionary technological change.
Body movements for ejaculation in externally fertilising fish are typically described as a rapid quiver/vibration of the body, and are often considered invariable in this group. A field study was ...conducted in the small marine fish, triplefin blenny (
Enneapterygius etheostoma
) to examine the possible variability of quiver motion, in relation to alternative reproductive tactics (i.e., sneakers and territorial males). Spontaneous ejaculation behavior recorded was quantified and compared between tactics using high-speed cameras. Ejaculation movements were kinematically discrete between tactics, with sneakers performing faster and larger undulation motions at a greater frequency, and traveling longer in time and distance than territorial males. Amplitude data showed that sneakers moved their whole bodies more than territorial males. The highest amplitudes were observed for the tail in sneakers and the head in territorial males. Overall, it called a whole-body wriggling motion for sneakers, and head vibration motion for territorial males. Sneakers spent 1/3 of the ejaculation period at a greater distance from spawning females. This may result from avoidance behaviour by sneakers but the fact that they aimed their genital papillae towards the surface of the spawning site rather than directed at the females introduces the possibility that sneakers may be targeting not just current reproduction (of newly laid eggs) but also future reproduction (of eggs laid later) as a way of offsetting potentially reduced fertilisation success due to their more distant proximity to the spawning female. Therefore, the present study suggests that different ecological demands shape tactic-specific ejaculation motions.
•MOFs-based ratiometric fluorescence sensors and their luminescent mechanism are described.•Design tactics of MOFs-based ratiometric fluorescence sensors are summarized on the basis of different ...emission of MOFs.•MOFs-based ratiometric fluorescence sensors for applications in temperature, ions, biomarkers and pH sensing are discussed.
Metal-organic frameworks (MOFs) are an important class of inorganic-organic hybrid crystals with applications in various fields. In last ten years, MOFs-based fluorescence sensing has gained much attention. MOFs can exhibit luminescence by metal nodes, ligands and the inserted or absorbed guests, which offer an excellent fluorescence response in analyzing. However, MOFs-based monochromatic fluorescence probes are limited by concentration, the effect of ambient and excitation light intensity, resulting in low detection accuracy. To overcome this defect, MOFs-based ratiometric fluorescence (RF) sensors have been proposed and rapidly developed. This review focuses on the design tactics of MOFs-based RF sensing and describes the detection mechanism of different RF sensors. Based on different strategies of synthesis, the MOFs-based RF sensors are categorized into three classes: MOFs’ intrinsic dual-emission, single-emissive MOFs with a chromophore and non-emissive MOFs with two chromophores. In each categorization, the design approaches and relative merits were discussed separately. Finally, the applications of MOFs-based RF sensors are summarized and prospected.

The exploitation of electrode materials with ability to balance capacity and kinetics between cathode and anode is a challenge for sodium‐ion hybrid capacitors (SIHCs). Mn‐based anode materials are ...limited by poor electrical conductivity, sluggish reaction kinetics, large volume variation, weak cycling stability, and inferior reversible capacity. Herein, MnS nanocubes encapsulated in S‐doped porous carbon matrix (MSC) with strong sulfur‐bridged bond interactions (CSMn) are successfully synthesized by solvent‐free tactics. The CSMn bonds generated between MnS and carbon significantly inhibit the aggregation of nanostructural MnS cubes, restrict the volume expansion, and stabilize the nanostructure, which improves the Na+ storage reversibility and stability. Moreover, S‐doped porous carbon enhances the electrical conductivity and electrons/ions diffusion rate, which boosts a fast kinetic reaction. As expected, MSC anode presents an outstanding reversible capacity of 600 mAh g‐1 at 0.2 A g‐1 and a long‐term stable capacity of 357 mAh g‐1 for 1000 cycles at a high current density of 10 A g‐1 in sodium‐ion batteries (SIBs). The as‐assembled SIHCs deliver a high energy density of 109 W h kg‐1 and a high power output of 98 W kg‐1, with 88% capacity retention at 2 A g‐1 after 2000 cycles and practical applications (55 LEDs can be lighted for 10 min).
MnS nanocubes encapsulated into S‐doped porous carbon matrix (MSC) with sulfur‐bridged bonds (CSMn) are synthesized via facile solvent‐free tactics, which can enhance the Na+‐storage properties with fast kinetics, superior reversibility, and long‐life stability.
