AbstractTwo highly relevant aspects of football, namely forecasting of results and performance analysis by means of performance indicators, are combined in the present study by analysing the value of in-play information in terms of event and positional data in forecasting the further course of football matches. Event and positional data from 50 matches, including more than 300 million datapoints were used to extract a total of 18 performance indicators. Moreover, goals from more than 30,000 additional matches have been analysed. Results suggest that surprisingly goals do not possess any relevant informative value on the further course of a match, if controlling for pre-game market expectation by means of betting odds. Performance indicators based on event and positional data have been shown to possess more informative value than goals, but still are not sufficient to reveal significant predictive value in-play. The present results are relevant to match analysts and bookmakers who should not overestimate the value of in-play information when explaining match performance or compiling in-play betting odds. Moreover, the framework presented in the present study has methodological implications for performance analysis in football, as it suggests that researchers should increasingly segment matches by scoreline and control carefully for general team strength.

Matrix models have been developed in order to plan and control the effects of complex interrelationships as well as to prepare for and make optimum decisions. For the purpose of tax planning, our investigations focus particularly on simultaneous analyses of the effects and structure of corporate tax, trade tax, deferred taxes, and performance indicators within the German legal area. In addition, the models can also be useful in accounting policy optimization when taking into account the amendments to the German authoritative principle that tax accounting should be based on commercial accounting

And Performance

Performance analysis during match play is vital for the long-term development of tennis players. The primary goal of this study was to establish the differences between junior and entry professional tennis player's selected performance indicators in five-game situations. Data were collected using the Sagit/Tennis tracking system during six junior and four professional tennis matches. Eight boys performed 3,112 strokes, while eight male professional players hit 1,631 strokes. The results showed slight differences in the distance covered by the two observed groups in the specific game situations. Professional players performed faster shots in all game situations, except when playing at the net. They played at a significantly faster tempo than the juniors. This difference was also affected by the higher shots speed and shorter distance between the two players during the rallies. When playing from the baseline, the entry professional players performed shots at a smaller angle than the juniors; and when serving, receiving and playing at the net, they hit shots at a greater angle than the juniors. Our findings may assist coaches and players in improving the effectiveness of their tactical and technical training to enhance their competitive performance.

And Training

Selection and training methods for showjumping horses are largely anecdotal, and performance analysis has been proposed as a method for scientifically improving competitive outcomes. To employ performance analysis in showjumping, an understanding of the tacit and explicit knowledge and practices of equestrians is required to identify relevant performance indicators. This study aimed to examine the knowledge and practices of equestrians with varying levels of experience (advanced and novice) for selecting horses, based on evaluation of movement, and training showjumping horses using an original questionnaire. It was hypothesised that differences would be present between advanced and novice responses. The questionnaire was composed of closed-end and follow-up open-end questions and 225 equestrians (66.7% advanced, 33.3% novice) participated. Closed-end responses from advanced and novice groups were analysed separately using Chi-Squared tests and open-end responses were subjected to thematic and content analysis. Closed-end responses showed significant within-group preferences (P<0.0001) for specific movement traits and training methods and between-group response differences <13% revealed that advanced and novice groups displayed similar preferences. Thematic analysis indicated different preferences for movement traits when selecting showjumping horses, as well as differences in the level of tacit knowledge between advanced and novice groups. Advanced equestrians placed greater emphasis on aesthetic forelimb traits than novice equestrians, who emphasised traits that they may be less capable of influencing, such as hindlimb impulsion and position of the horse at take-off. An emphasis on hindlimb movement and flatwork/non-jumping exercises for showjumping training was observed across both groups. Understanding equestrian tacit knowledge and its application is fundamental for developing research that is relevant to equestrians. Findings from this study may form a basis for research to identify relevant, objective performance indicators for performance analysis in showjumping, with the ultimate goal of improving competitive performance and welfare for equine athletes.

Main Effects

This study puts particular emphasis on the role of copper ions in the performance of hydrogen peroxide bleaching (P-stage). Owing to their variable levels across the bleaching line due to washing filtrates, bleaching reagents, and equipment corrosion, these ions can play a major role in hydrogen peroxide decomposition and be detrimental to polysaccharide integrity. In this study, a Cu-contaminated D0(EOP)D1 prebleached pulp was subjected to an acidic washing (A-stage) or chelation (Q-stage) before the alkaline P-stage. The objective was to understand the isolated and combined role of copper ions in peroxide bleaching performance. By applying an experimental design, it was possible to identify the main effects of the pretreatment variables on the extent of metals removal and performance of the P-stage. The acid treatment was unsuccessful in terms of complete copper removal, magnesium preservation, and control of hydrogen peroxide consumption in the following P-stage. Increasing reaction temperature and time of the acidic A-stage improved the brightness stability of the D0(EOP)D1AP bleached pulp. The optimum conditions for chelation pretreatment to maximize the brightness gains obtained in the subsequent P-stage with the lowest peroxide consumption were 0.4% diethylenetriaminepentaacetic acid (DTPA), 80ºC, and 4.5 pH.
