Speech is a vital means of communication for completing many tasks. The speech intelligibility needed for successful communication may be degraded by ambient noise levels, poor communication equipment, or hearing impairments. The present research tested the impact of speech message content on task performance under conditions of degraded speech intelligibility. Sixteen subjects participated in a laboratory experiment using on a board game. Message redundancy, morphological confusions, and speech intelligibility were varied. Task performance and subjective workload were measured. Morphological confusions adversely affected performance (both speed and accuracy) and subjective workload (SWAT) to an increasingly greater extent as speech intelligibility decreased. High redundancy improved the accuracy of performance and subjective workload when speech intelligibility decreased; however, high redundant messages were longer and required more time to process than low redundant messages. These results extend earlier work which measured the impact of morphological confusions and redundancy on speech intelligibility itself to the measurement of their impact on performance. Implications for the development of message content guidelines and their impact on performance are discussed.

The Relationship

Introduction: Mounting evidence suggests that mindfulness is positively related to athletic performance and athlete wellbeing. However, few attempts have been made to uncover the psychological processes by which mindfulness might impact performance. Objective: To determine whether negative self-appraisal mediates the relationship between mindfulness and the confidence component of mental toughness among provincial adolescent female hockey players. Methods: Provincial adolescent female hockey players (N=486) completed measures of mindfulness, mental toughness-related confidence and negative self-appraisal. Correlation coefficients were calculated between all variables included in the study. An ordinary least-squares regression analysis was performed to test the indirect effect of negative self-appraisal on the relationship between mindfulness and confidence. Results: Negative self-appraisal exhibited an indirect effect on the relationship between mindfulness and the confidence component of mental toughness (b = .06, SE = .0, CI95 = .04, .09). A subsequent Soble test confirmed that negative self-appraisal served as a statistically significant mediator (b = .06, SE = .01, Z = 5.76, p = .001) in the model. Furthermore 78.3% of the variance in the effect of mindfulness on the confidence component of mental toughness was accounted for by negative self-appraisal. Conclusion: The effect of mindfulness on the confidence component of mental toughness among adolescent athletes is mediated by negative self-appraisal. Based on the current findings, mindfulness seems to foster confidence by lessening the impact of rigid negative appraisals of one’s performance and worth as an athlete.

The Impact

The rapid increase of poverty, crime, and unemployment in South Africa results in youth vulnerability. Youth not in employment, not in education, and not in training are most vulnerable to life setbacks, find it difficult dealing with criticism, rejection, and failure. Thus, youth workers responsible for the coordination of youth service programme need to design an autonomy-supportive programme that can prepare youth mentally before youth are placed in a youth development programme that seeks to enhance youth employability. The National Youth Development Agency in South Africa under the National Youth Service Programme has developed a mental toughness programme curriculum that NYS volunteers undergo before participating in youth skill development programme or community service programme for a minimum of five days. The aim of the study is to explore the impact of the Mental Toughness Programme on the positive development of youth through youth lived experience in the Western Cape Province, South Africa. This study made use of a qualitative research approach, non-probability sampling to sample eight youth who participated in the Mental Toughness Programme offered by the National Youth Development Agency. In this study, we recommend that the National Youth Development Agency knowledge and research division should conduct a longitudinal study that can evaluate the impact of the Mental Toughness Programme on positive youth development in South Africa. The National Youth Development Agency should revise the mental toughness programme curriculum in a way that the programme goes beyond five days and physical toughness should be cooperated in the curriculum to enhance social cohesion.   Received: 27 July 2021 / Accepted: 6 October 2021 / Published: 3 January 2022

The article covers the issue of playing activities in basketball. The value of speed and accuracy of basketball players' game actions is revealed. The dependence of basketball players' game efficiency on indicators of their psychophysical development of their organism and the need to study the influence of morphofunctional and psychophysiological indicators of basketball players on the speed and accuracy of game actions are substantiated. In sports games, technical training is of great importance, which includes a large number of different techniques. Basketball activity is based on individual and group technical actions of athletes, the main of which are throws to the basket, passes, driving, interception, selection, selection of the ball, etc. The ability to perform these actions quickly and accurately is the main condition for a successful game of basketball players. Game efficiency depends on the spatio-temporal characteristics of game actions, which, in turn, are determined by the peculiarities of the psychophysical development of the body of athletes. One of the main ways to achieve high sportsmanship is the constant improvement of the technique of the chosen sport, the study of its structure, components and psychophysiological basis. Therefore, the study of the parameters of the game activities of students who play basketball, which includes analysis of the impact of morphofunctional and psychophysiological indicators of the body on competitive efficiency, is relevant in today's conditions of intensification of sports training.

The Impact

For a long time, competitive sport has focused only on aspects related to performance. However, studies in social psychology have indicated the importance of focusing on the human development of athletes, which can occur through training environments that promote psychological well-being. Thus, this study aimed to analyze the impact of the coach-athlete attachment style, mediated by the coach’s leadership style, on the mental toughness of athletes in the world beach volleyball context. Elite beach volleyball athletes (n = 65), participants of the World Tour 2018, were part of the study. The Coach-Athlete Attachment Scale (CAAS), Mental Toughness Index (MTI) and Leadership Scale for Sport (LSS) were used as instruments. For data analyses we used polychoric correlation and a bias-corrected factor score path analysis. Path analysis showed that perceived secure attachment was positively associated with athletes’ mental toughness (0.24; 0.31; 0.25), but leadership styles did not mediate this relationship. For athletes with anxious attachment profiles, the perception of autocratic leadership style was associated with athletes’ mental toughness (1.01; p = 0.03), when their interaction style is focused on coaching-instruction. It concludes that the secure attachment relationship can bring increases in levels of athletic mental toughness, whereas for athletes with insecure attachment, the autocratic style was shown to be associated with the highest levels of mental toughness.

Distal Vessel

The availability of telemanipulation robots has not yet resulted in the emergence of a reliable endoscopic coronary bypass procedure. A major challenge in performing a closed-chest coronary operation is creating a high-quality anastomosis in a reasonable period of time. In this experimental study, the impact of distal vessel orientation on the speed and accuracy of anastomosis was quantifed. We found that vessel orientation and the relative angle of the surgical plane influence anastomosis speed, the trauma to the vessel, the accuracy of stitch placement, and the eventual achievement of hemostasis. Our results suggest that the speed and accuracy of a robotically performed anastomosis of a vessel graft to a coronary artery can be improved by making small changes in vessel orientation. Vessels should be positioned between the horizontal and diagonal orientation and inclined between the horizontal and +45. Because the 6-o'clock stitch is particularly challenging, surgeons may benefit from an orientation that moves the heel or the toe of the anastomosis away from this critical position.

The aim of this study was to examine the impact of maximum sprint speed on peak and mean sprint speed during youth female field hockey matches. Two high-level female field hockey teams (U-17, n = 24, and U-21, n = 20) were monitored during a 4-game international test series using global position system technology and tested for maximum sprint speed. Dependent variables were compared using a 3-factor ANOVA (age group, position, and speed classification); effect sizes (Cohen d) and confidence limits were also calculated. Maximum sprint speed was similar between age groups and positions, with faster players having greater speed than slower players (29.3 ± 0.4 vs 27.2 ± 1.1 km/h). Overall, peak match speed in youth female field hockey players reaches approximately 90% of maximum sprint speed. Absolute peak match speed and mean sprint speed during matches were similar among the age groups (except match 1) and positions (except match 2); however, peak match speed was greater for faster players in matches 3 and 4. No differences were observed in the relative proportion for mean sprint speeds for age groups or positions, but slower players consistently displayed similar relative mean sprint speeds by using a greater proportion of their maximum sprint speed.

Data mining helps to solve many problems in the area of medical diagnosis using real-world data. However, much of the data is unrealizable as it does not have desirable features and contains a lot of gaps and errors. A complete set of data is a prerequisite for precise grouping and classification of a dataset. Preprocessing is a data mining technique that transforms the unrefined dataset into reliable and useful data. It is used for resolving the issues and changes raw data for next level processing. Discretization is a necessary step for data preprocessing task. It reduces the large chunks of numeric values to a group of well-organized values. It offers remarkable improvements in speed and accuracy in classification. This paper investigates the impact of preprocessing on the classification process. This work implements three techniques such as NaiveBayes, Logistic Regression, and SVM to classify Diabetes dataset. The experimental system is validated using discretize techniques and various classification algorithms.
