Performance analysis (PA) involves the systematic observation and analysis of factors identified to enhance performance to improve athlete decision-making in a specific sport. PA is commonplace in human sports, yet despite potential advantages, its application remains limited in equestrianism. This study aimed to evaluate if factors anecdotally associated with performance in elite showjumping influenced competitive success. 250 combinations attempting 3,052 jumping-efforts across 2nd round European Fédération Equestre Internationale Nations Cup 2017 competition were analysed. Types of fault (e.g. pole down, refusal, etc.) were recorded as well as characteristics of the jump (e.g. jump type, approach angle). Combinations jumped clear at the majority of attempts (93.6; n=2,857) with faults only occurring at 6.4% of jumps (n=195). The most common faults were knock-downs (5.5%), time penalties (0.8%), faults at water jumps (0.3%) and refusal (0.2%). Faults were distributed across all fence types, however, were more common at upright fences (49%) and within combination fences (41%). A linear relationship was found between jumping-effort number and number of fences knocked-down (r=0.7; P<0.001). There were 2.8 times more knock-downs for the second half of the course (efforts 9-15) compared with jumping-efforts 1-7 (P<0.05). Faults were 4 times more likely at jumping-efforts 3, 4, 5 and 8 in the first half of the course (P<0.03) which increased to being 9 times more likely in the 2nd half of the courses (jumping-efforts 9, 10, 11, 12, 13 and 14; P<0.006). A straight approach to a jumping-effort reduced the chance of faults by 48% (P<0.0001) compared to a non-straight approach. These preliminary results suggest faults are not randomly distributed in elite showjumping and that patterns exist within fault accumulation demonstrating that the application of PA techniques in equestrian sport could lead to a performance advantage.

The use of performance analysis is commonplace throughout competitive sports, however, uptake is limited within equestrianism. This review considers the potential for wider implementation of performance analysis techniques within equine sports via contextualisation to showjumping: the horse, rider and the horse and rider dyad. There appears to be limited research available to underpin evaluation of the multiple facets that comprise competitive success in showjumping, with biomechanical evaluation of the jumping phases most established. This presents opportunities for collaboration between the equine industry, researchers and performance analysts to expand knowledge of what contributes to success for horse and rider partnerships in all equine disciplines.

This article focuses on the decision-making processes involved in research and knowledge integration in translation processes. First, the relevance of decision taking intranslation is discussed. Second, the psychology of decision making as seen by Jungermann et al. (2005) is introduced, who propose a categorization of decision-making processes intofour types: “routinized”, “stereotype”, “reflected” and “constructed”. This classification is then applied to the translations by five professional translators and five novices of five segments occurring in a popular-science text. The analysis reveals that the decision-making types are distributed differently among students and professional translators, which also has to be seen against the background of whether the decisions made were successful or not. The preliminary results of this study show that students resort to reflected decisions in most cases, but with a low success rate. Professionals achieve a higher success rate when making reflected decisions. As expected, they also make more routinized decisions than students. The professionals’ success rates improve with increasing cognitive involvement, while their failure rates are relatively high when making routinized decisions, an aspect worthwhile considering in translation didactics.

VoIP stands for voice over internet protocol. It is one of the most widely used technologies. It enables users to send and transmit media over IP network. The transition from IPv4 to IPv6 provides many benefits for internet IPv6 is more efficient than IPv4. This paper presents a performance analysis of VoIP over WLAN using IPv4 and IPv6 and OPNET software program to simulate the protocols and to investigate the QoS parameters such as jitter, delay variation, packet send, and packet received and throughputs for IP4 and IP6 and compare between them.
