El propósito del estudio fue analizar el conocimiento procedimental, en función de la experiencia y el rendimiento, en jóvenes jugadores de voleibol de categoría cadete. La muestra de estudio estuvo compuesta por un total de 301 jugadores y jugadoras de voleibol, de categoría cadete, con edades comprendidas entre 14-16 años. Dichos jugadores correspondían a los 32 equipos participantes en el Campeonato de España de Selecciones Autonómicas de 2011. Las variables independientes fueron el rendimiento, y la experiencia en práctica federada. La variable dependiente fue el conocimiento procedimental, medido a través del cuestionario elaborado y validado por Moreno (2006). Los resultados, a través de la prueba post-hoc de Tukey, mostraron diferencias significativas en el conocimiento procedimental en función de la experiencia y el rendimiento. Además, un análisis de correlación mostró una relación lineal y significativa entre las variables experiencia en práctica federada y conocimiento procedimental. Dichos resultados ponen de manifiesto la importancia de la experiencia para el desarrollo del conocimiento procedimental en deportes de equipo, en los cuales las exigencias tácticas poseen una gran relevancia. Por ello, es recomendable continuar realizando estudios que permitan relacionar diferentes tipos, contextos y niveles de práctica deportiva con los aspectos cognitivos de los deportistas, con el fin de aportar pautas que orienten el proceso de formación deportiva.Palabras claves: procesos cognitivos, etapas de formación, experiencia, voleibol.Abstract: The aim of the study was to analyze the procedural knowledge, based on experience and performance, in young volleyball players. The sample consisted of 301 Under-16, volleyball players. They belonged to the 32 teams participating in the Spanish Championship of Regional Selections in the 2011 season. The independent variables were performance and experience in federative practice. The dependent variable was procedural knowledge, it was measured by the questionnaire developed and validated by Moreno (2006). The results, through post-hoc test of Tukey, showed significant differences in procedural knowledge, based on experience and performance. Also a correlation analysis showed a significant linear relationship between experience in federated practice and procedural knowledge was founded. These results highlight the importance of experience for the development of procedural knowledge in team sports. It also emphasize the importance of experience for the development of procedural knowledge in team sports, in which the tactical requirements have great relevance. Thus, it is recommended to continue doing studies that connect different types, levels and contexts of practice with the cognitive aspects of athletes, in order to provide guidelines to lead the process of sports training.Keywords: cognitive processes, training stages, experience, performance, volleyball.

In the sport psychology, the theories of motivation, such as the McClelland's need achievement theory and the Nicholls' achievement goal theory, play an important role in the team sports in motivating and encouraging team members. The practical implementation of these theories relies on detecting the variables that significantly affect the probability of winning so as to identify the key elements for the team motivation, the role assignment, and the decision-making process. As the relevant variables change in accordance with the type of sport, in this contribution we focus on the basketball. In detail, we consider the traditional box score of the U.S. National Basket Association (NBA) regular season games played in the seasons 2016-17, 2017-18, 2018-19 and 2020-21. Each season comprises of 82 games played by each of the 30 teams, which cumulates to 4920 games. Hence, data have a multilevel structure, with multiple observations for each team. To properly address the data structure, the probability of winning is modelled through a random-intercept logit model, where teams are the upper-level units and games are the lower-level units. Among the independent variables, we take into account several possible determinants of winning, such as number of assists, number of offensive rebounds, number of defensive rebounds, number of turnovers, number of stolen balls, percentage of free throws made, number of fouls made. Moreover, we devote a special attention to the effect of two more independent variables: the number of key-players that are missing or injured and a dummy if the team plays without a day of rest between consecutive games. The study provides insights in the determinants of success of the basketball games: these results can be used by the team decision makers to assign roles that favor motivation and performance of players and of team as a whole.

The purpose of this study is to identify the effect of using dynamic software Google SketchUp (GSU), without software on van Hiele’s theory and conventional teaching strategy of students’ conceptual and procedural knowledge in learning geometry among primary school students. The study was conducted using pre and post-test true experimental methods. This true experimental research involved 96 students from Year Five primary schools in Malaysia. The selection of site or school take into account as convenience and voluntary participation. The study's findings showed significant differences in student's conceptual knowledge and procedural knowledge based on the different types of the strategy group. The post hoc test indicated that using software showed better conceptual and procedural knowledge when compared to without using software on van Hiele’s theory and conventional teaching strategy.

Physiological Reactions

This study tests whether playing violent video games leads to desensitization and increased cardiovascular responding. In a laboratory experiment, 42 men spent 20 min playing either a high- or low-violence version of a “first-person shooter” game. Arousal (heart rate, respiration rate) was measured continuously. After playing the game, emotional responses to aversive and aggressive stimuli - pictures from Lang, Bradley, and Cuthbert’s (1999) International Affective Picture System - were assessed with self-ratings and physiological measurement (skin conductance). Results showed no differences in the judgments of emotional responses to the stimuli. However, different effects of game violence emerged in the physiological reactions to the different types of stimulus material. Participants in the high-violence condition showed significantly weaker reactions (desensitization) to aversive stimuli and reacted significantly more strongly (sensitization) to aggressive cues. No support was found for the arousal hypothesis. Post-hoc analyses are used to discuss possible moderating influences of gaming experience and player’s trait aggressiveness in terms of the General Aggression Model ( Anderson & Bushman, 2001 ) and the Downward Spiral Model ( Slater, Henry, Swaim, & Anderson, 2003 ).

ABSTRACT This study compares key characteristics and performance of physicians referred to a clinical competence assessment and education program by state medical boards (boards) and hospitals. Physicians referred by boards (400) and by hospitals (102) completed a CPEP clinical competence assessment between July 2002 and June 2010. Key characteristics, self-reported specialty, and average performance rating for each group are reported and compared. Results show that, compared with hospital-referred physicians, board-referred physicians were more likely to be male (75.5% versus 88.3%), older (average age 54.1 versus 50.3 years), and less likely to be currently specialty board certified (80.4% versus 61.8%). On a scale of 1 (best) to 4 (worst), average performance was 2.62 for board referrals and 2.36 for hospital referrals. There were no significant differences between board and hospital referrals in the percentage of physicians who graduated from U.S. and Canadian medical schools. The most common specialties referred differed for boards and hospitals. Conclusion: Characteristics of physicians referred to a clinical competence program by boards and hospitals differ in important respects. The authors consider the potential reasons for these differences and whether boards and hospitals are dealing with different subsets of physicians with different types of performance problems. Further study is warranted.

The Relationship

Despite the continuous interest in studying entrepreneurial teams, the relationship between team composition and, particularly, team diversity and performance remains fertile ground for active debate. Taking roots in the knowledge-based view and organizational learning literatures, this chapter argues that performance in entrepreneurial teams is contingent on (a) the overlap between team members’ knowledge/competences and the content of the performed tasks, (b) the duplication of the team members’ knowledge in the areas with that content, (c) the nature of tasks (exploration or exploitation), (d) the team’s flexibility to adapt to changes in the content and nature of those tasks, and (e) the rate of environmental change. Because an important source of ambiguity in the understanding of how team diversity and performance are linked ties to issues of how team diversity is conceptualized and operationalized, the chapter also proposes a new way of looking at diversity in future research.

Ici Cancellation

In this article, the authors investigate the enhanced two stage MMSE (TS-MMSE) equalizer in bit-interleaved coded FBMC/OQAM system which gives a tradeoff between complexity and performance, since error correcting codes limits error propagation, so this allows the equalizer to remove not only ICI but also ISI in the second stage. The proposed equalizer has shown less design complexity compared to the other MMSE equalizers. The obtained results show that the probability of error is improved where SNR gain reaches 2 dB measured at BER compared with ICI cancellation for different types of modulation schemes and ITU Vehicular B channel model. Some simulation results are provided to illustrate the effectiveness of the proposed equalizer.

The development of robotic systems to operate in forest environments is of great relevance for the public and private sectors. In this sense, this article reviews several scientific papers, research projects and commercial products related to robotic applications for environmental preservation, monitoring, wildfire firefighting, inventory operations, planting, pruning and harvesting. After conducting critical analysis, the main characteristics observed were: (a) the locomotion system is directly affected by the type of environmental monitoring to be performed; (b) different reasons for pruning result in different locomotion and cutting systems; (c) each type of forest, in each season and each type of soil can directly interfere with the navigation technique used; and (d) the integration of the concept of swarm of robots with robots of different types of locomotion systems (land, air or sea) can compensate for the time of executing tasks in unstructured environments. Two major areas are proposed for future research works: Internet of Things (IoT)-based smart forest and navigation systems. It is expected that, with the various characteristics exposed in this paper, the current robotic forest systems will be improved, so that forest exploitation becomes more efficient and sustainable.

The Relationship

A debate over the past decade has focused on the so-called bilingual advantage—the idea that bilingual and multilingual individuals have enhanced domain-general executive functions, relative to monolinguals, due to competition-induced monitoring of both processing and representation from the task-irrelevant language(s). In this commentary, we consider a recent study by Pot, Keijzer, and de Bot (2018), which focused on the relationship between individual differences in language usage and performance on an executive function task among multilingual older adults. We discuss their approach and findings in light of a more general movement towards embracing complexity in this domain of research, including individuals’ sociocultural context and position in the lifespan. The field increasingly considers interactions between bilingualism/multilingualism and cognition, employing measures of language use well beyond the early dichotomous perspectives on language background. Moreover, new measures of bilingualism and analytical approaches are helping researchers interrogate the complexities of specific processing issues. Indeed, our review of the bilingualism/multilingualism literature confirms the increased appreciation researchers have for the range of factors—beyond whether someone speaks one, two, or more languages—that impact specific cognitive processes. Here, we highlight some of the most salient of these, and incorporate suggestions for a way forward that likewise encompasses neural perspectives on the topic.

The recent proliferation of artificial intelligence (AI) gives rise to questions on how users interact with AI services and how algorithms embody the values of users. Despite the surging popularity of AI, how users evaluate algorithms, how people perceive algorithmic decisions, and how they relate to algorithmic functions remain largely unexplored. Invoking the idea of embodied cognition, we characterize core constructs of algorithms that drive the value of embodiment and conceptualizes these factors in reference to trust by examining how they influence the user experience of personalized recommendation algorithms. The findings elucidate the embodied cognitive processes involved in reasoning algorithmic characteristics – fairness, accountability, transparency, and explainability – with regard to their fundamental linkages with trust and ensuing behaviors. Users use a dual-process model, whereby a sense of trust built on a combination of normative values and performance-related qualities of algorithms. Embodied algorithmic characteristics are significantly linked to trust and performance expectancy. Heuristic and systematic processes through embodied cognition provide a concise guide to its conceptualization of AI experiences and interaction. The identified user cognitive processes provide information on a user’s cognitive functioning and patterns of behavior as well as a basis for subsequent metacognitive processes.
