In recent years, there has been an increasing number of investigations analyzing the effects of sex, performance level, and age on pacing in various running disciplines. However, little is known about the impact of those factors on pacing strategies in ultramarathon trail running. This study investigated the effects of age, sex, and performance level on pacing in the UTMB® (Ultra-trail du Mont Blanc) and aimed to verify previous findings obtained in the research on other running disciplines and other ultramarathon races. Data from the UTMB® from 2008 to 2019 for 13,829 race results (12,681 men and 1148 women) were analyzed. A general linear model (two-way analysis of variance (ANOVA)) was applied to identify a sex, age group, and interaction effect in pace average and pace variation. A univariate model (one-way ANOVA) was used to identify a sex effect for age, pace average, and pace variation for the fastest men and women. In our study, pace average and a steadier pace were positively correlated. Even pacing throughout the UTMB® correlated with faster finishing times. The average pace depended significantly on sex and age group. When considering the top five athletes in each age group, sex and age group also had significant effects on pace variation. The fastest women were older than the fastest men, and the fastest men were faster than the fastest women. Women had a higher pace variation than men. In male competitors, younger age may be advantageous for a successful finish of the UTMB®. Faster male runners seemed to be younger in ultramarathon trail running with large changes in altitude when compared to other distances and terrains.

Driving involve activities some components including drivers, vehicles, passenger, roads, and the surrounding environment that interact with each other. Based on the website Badan Intelegensi Negara (BIN), it is said that one of the main causes of traffic accidents is the diver’s negligence. Data of Polrestabes Bandung City for the February 2014 to February 2015 showed that the rate of accidents, especially personal cars, had fluctuated. The driver factor that is the cause of the accident is most likely due to fatigue. The risk of work fatigue is on of them is stress. The impact of stress can disrupt driving performance arising from negative moods. Aim of this study was to analyze the stress and performance levels of driver personal car using salivary alpha amylase and stroop test parameters. The results of the study for sleep adequate treatment and lack of sleep treatment before and after simulation on stress levels (p-value (sig.) > α, 0,174; 0,351 > 0,05) and performance levels (p-value (sig.) > α, 0,546; 0,904 > 0,05) showed a significant distinction. While for stress level (p-value (sig.) > α, 0,365 > 0,05) about adequate sleep and lack of sleep treatment before and after simulation showed a significant distinction and performance level (p-value (sig.) > α, 0,915 > 0,05) showed a significant distinction. The coefitient correlation between stress level and performance level are 0.4, which mean there is strong correlation between stress level and performance level.

Reaction Speed

Summary The soccer goalkeeper's reaction speed to stimulus is essential for the overall success rate of goalkeepers in soccer. Our research was aimed at finding out the impact of age and agility performance level on the length of the disjunctive reaction time of elite goalkeepers in Slovakia. The research group was comprised of 24 goalkeepers of two Slovak soccer clubs (in group A were elite players and in group B sub-elite players). To gain the research data, the disjunctive reaction time was measured using the Fitro Agility Check device. The acquired results were statistically evaluated using the Mann-Whitney U-Test and Cohen's “d”. The impact of age (n.s) and performance level (n.s) on the length of the disjunctive reaction time of goalkeepers was not statistically confirmed. However, the substantive and logical significance showed that the best goalkeepers achieved a considerably shorter time of disjunctive reaction time to the set stimulus (difference – 20 %).

The Impact

The paper provides new survey evidence on effects of concentrated ownership upon investment and performance in Russian industrial enterprises. Authors trace major changes in their ownership profile, assess pace of post-privatization redistribution of shareholdings and provide evidence on ownership concentration in the Russian industry. The major econometric findings are that the first largest shareholding is negatively associated with the firm’s investment and performance but surprisingly the second largest shareholding is positively associated with them. Moreover, these relationships do not depend on identity of majority shareholders. These results are consistent with the assumption that the entrenched controlling owners are engaged in extracting "control premium" but sizable shareholdings accumulated by other blockholders may put brakes on their expropriating behavior and thus be conductive for efficiency enhancing. The most interesting topic for further more detailed analysis is formation, stability and roles of coalitions of large blockholders in the corporate sector of post-socialist countries.

The Relationship

The State of Qatar has implemented several family policies in order to improve the wellbeing of Qatari families and ensure fair distribution of development benefits for both men and women. However, there is a linkage between female employment outside the home and instability in the marriages of Qatari families. This paper investigates the impact of female employment on marital stability, based on the results of primary data collected in Qatar, a questionnaire that consisted of several sections such as challenges in the workplace, supervisor, family and spouse relations, work motivation and performance. Of the 824 questionnaires that were returned, 807 were completed and valid for analysis. Regression analysis and an ANOVA test have been used to test the relationship between the variables. The results of the research have produced mixed findings about how wives’ employment increases marital instability and have yielded few significant differences on mean scores of discuss on work demands, insufficient time together, housework, financial matters, communication, relatives and rearing children. The results indicates that in general Qatar working women face several challenges in relation to their marital life as part of cultural and social constraints.

Rapid Transformation

Abstract Agri-food systems include branching ramifications, which connect in the upstream the input suppliers with farmers, and downstream farmers, processors, retailers and consumers. In the last decades, at the level of the regions, food systems have undergone rapid transformation as a result of technological progress. The paper analyzes the changes made to the structure, behavior and performance of the agri-food system and the impact on farmers and consumers. Also, the role of agricultural research as a determinant factor of transformation of agri-food system is analyzed. The research objective is to develop technologies that cover the entire food chain (from farm to fork) and meet the specific requirements of consumers (from fork to farm) through scientific solutions in line with the principles of sustainable agriculture and ensuring the safety and food safety of the population.
