Set pieces are important for the success of football teams, with the corner kick being one of the most game defining events. The aim of this research was twofold: (1) to analyze the corner kicks of a senior football amateur team, and (2) to compare the corner kicks of successful and unsuccessful teams (of the 2020/21 sporting season). In total, 500 corners were observed using a bespoke notational analysis tool, using a specific observational instrument tool (8 criteria; 25 categories). Out of the 500 corner kicks, 6% resulted in a goal. A greater number of direct corners using inswing trajectories were performed (n = 54%). Corners were delivered to central and front post areas most frequently (n = 79%). Five attackers were most predominantly used for offensive corners (n = 58%), but defenders won the ball more frequently (n = 44%). Attempts at goal occurred following a corner most commonly from outside of the box (n = 7%). Goals were scored most frequently with the foot (n = 16%) and head (n = 15%). Successful teams are more effective at reaching the attackers and score more goals directly from corners. Unsuccessful teams deliver more corner kicks out of play, the first touch is more frequently from the opposition defenders, and fewe goals are scored from corner kicks. The study provides an insight into the determining factors and patterns that influence corner kicks and success in football matches. This information should be used by coaches to prepare teams for both offensive and defensive corner kicks to increase team success and match outcomes.

Within the determining factors of psychological performance, mental toughness is considered a multidimensional factor, comprising cognitive, affective, and behavioural components together with self-confidence, which is related to success in sports performance as well as psychological health and well-being. The aim of this study was to analyse the relationship between different factors composing mental toughness and age categories in young football players, in order to determine the presence of specific psychological skills in their formative progression. A total of 118 male players (16.91 ± 2.42 years old) completed the Spanish version by Cernuda (1988) of the original Psychological Performance Inventory (PPI) by Loher (1982, 1986). The results indicated significant differences in four variables (negative energy control, attention control, visual and image control, motivational level) on three different age categories, where the U19 category showed the best results for all the variables, decreasing afterwards in the semi-professional category. Significant correlations were established between mental toughness variables and age categories, where the age category variable was significantly correlated in a positive way with attention control, visual and image control, and motivational level. In the same line, the variable self-confidence correlated positively with negative energy control, attention control, motivational level, attention control, and positive energy. The assessment of psychological variables such as mental toughness, taking into account the formative stage, may be helpful for both coaches and players when selecting adequate mental skill training for improving competitive performance and sporting success, as well as for positive and healthy psychological development and well-being.

Self-tuning physical database organization involves tools that determine automatically the best solution concerning partitioning, placement, creation and tuning of auxiliary structures (e.g. indexes), based on the workload. To the best of our knowledge, no tool has focused on a relevant issue in parallel databases and in particular data warehouses running on common off-the-shelf hardware in a sharednothing configuration: determining the adequate tradeoff for balancing load and availability with costs (storage and loading costs). In previous work, we argued that effective load and availability balancing over partitioned datasets can be obtained through chunk-wise placement and replication, together with on-demand processing. In this work, we propose ChunkSim, a simulator for system size planning, performance analysis against replication degree and availability analysis. We apply the tool to illustrate the kind of results that can be obtained by it. The whole discussion in the chapter provides very important insight into data allocation and query processing over shared-nothing data warehouses and how a good simulation analysis tool can be built to predict and analyze actual systems and intended deployments.

Abstract Background Several literature reviews have been published focusing on the prevalence and/or preventability of hospital readmissions. To our knowledge, none focused on the different causes which have been used to evaluate the preventability of readmissions. Insight into the range of causes is crucial to understand the complex nature of readmissions. With this review we aim to: 1) evaluate the range of causes of unplanned readmissions in a patient journey, and 2) present a cause classification framework that can support future readmission studies. Methods A literature search was conducted in PUBMED and EMBASE using “readmission” and “avoidability” or “preventability” as key terms. Studies that specified causes of unplanned readmissions were included. The causes were classified into eight preliminary root causes: Technical, Organization (integrated care), Organization (hospital department level), Human (care provider), Human (informal caregiver), Patient (self-management), Patient (disease), and Other. The root causes were based on expert opinions and the root cause analysis tool of PRISMA (Prevention and Recovery Information System for Monitoring and Analysis). The range of different causes were analyzed using Microsoft Excel. Results Forty-five studies that reported 381 causes of readmissions were included. All studies reported causes related to organization of care at the hospital department level. These causes were often reported as preventable. Twenty-two studies included causes related to patient’s self-management and 19 studies reported causes related to patient’s disease. Studies differed in which causes were seen as preventable or unpreventable. None reported causes related to technical failures and causes due to integrated care issues were reported in 18 studies. Conclusions This review showed that causes for readmissions were mainly evaluated from a hospital perspective. However, causes beyond the scope of the hospital can also play a major role in unplanned readmissions. Opinions regarding preventability seem to depend on contextual factors of the readmission. This study presents a cause classification framework that could help future readmission studies to gain insight into a broad range of causes for readmissions in a patient journey. In conclusion, we aimed to: 1) evaluate the range of causes for unplanned readmissions, and 2) present a cause classification framework for causes related to readmissions.

Introduction. The most common cause of sideropenic anemia in infants, during the period of their fast growth and development, is inadequate nutrition or insufficient intake of food rich in iron. The aim of this paper is to provide the insight into the problem of anemia and to emphasize nutrition as an important etiologic factor in the onset and prevention of anemia in infants. Material and Methods. Two retrospective studies were conducted at the Institute for Child and Youth Healthcare of Vojvodina, Department for Infant and Small Children?s Pathology. The first study covered the period of eight years (1988-1995), and it included a total of 507 children, aged 1-24 months. The second study covered the period of two years (2010-2011) and a total of 290 children aged 1-12 months were included. The diagnosis of anemia was made according to clinical examination or after taking routine laboratory tests. According to the criteria of the World Health Organization, all children were divided into those with severe, moderate or mild anemia. Results. Out of 507 children examined in the first study, 333 (65.68%) were breastfed, while 174 (34.32%) had never been breastfed. In the second study, 206 (71.03%) out of 290 children were breastfed, while 56 (19.31%) had never been breastfed. In both studies the highest percentage of children breastfed for the longest period was among children with mild form of anemia, while the children who were breastfed for the shortest period had severe anemia. In addition, the highest percentage of anemic children was supplementary fed with cow?s milk in both studies. Conclusion. Short natural diet, early introduction of supplementation and choice of milk could be determining factors in the development and manifestation of anemia.

Insight Into

Football is widely referred to as the ‘beautiful game’. This gives the impression that the sport can be aesthetically appreciated by its human observers. However, while many people might acknowledge that some of the physical movements made by top level football players exhibit grace, even beauty, this does not equate to football being accepted as a form of culture comparable to other areas of human activity described collectively as ‘the arts’. While this article takes an interest in philosophical inquiry into the aesthetic possibilities of football, it is primarily concerned with a sociological explanation as to how football has become ‘artified’. In doing so, the article draws upon the concept ‘artification’ as developed by Roberta Shapiro and Nathalie Heinich. The approach is not concerned with definitions of art according to aesthetic criteria or notions of appreciation, but with ‘how and under what circumstances art comes about’. This requires examining football in relation to discernible ‘constituent processes’ of artification. For reasons explained in the article, the contextual focus is on the artification of football in England. Artification is not a closed and finished matter. In that it can be said to have occurred, artification must be balanced against ‘de-artification’ in the form of potentially countervailing tendencies. Such consideration is taken up in the conclusion, via reflection upon the damaging impact of the excesses of commercial organisational control. Overall, artification is advocated as a sociological model that offers insight into the cultural significance of football in contemporary life.

Insight Into

In the context of recent studies on writing to learn, concept maps are constructed in an attempt to make knowledge structures and conceptual change explicit. These graphic representations are based on the concepts and semantic relations in a student's text. However, a concept map does not give insight into the rhetorical text structure and other rhetorical features, nor does it show the way concepts are located and connected in this structure. Since the dialectic between content knowledge and rhetorical knowledge is essential in the process of 'knowledge transforming', and consequently conceptual change, an analysis tool that integrates both analysis of rhetorical text structure and of semantic structures in text is needed. In a pilot study of a forthcoming research project about writing to learn in the content areas in primary education, an instrument was designed for integrated text analysis and graphic representation. The analysis and representations were demonstrated with data collected from ll-to-12 year old students, who wrote an explanatory text for younger students about a climate issue. Revision was triggered by asking the student whether he expected a younger pupil to understand the written explanation. An analysis and graphic representations of two texts written by two different students focused on location and use of concepts, expansions of meaning of these concepts, and connections between concepts through coherence relations, all embedded in the rhetorical text structure. It was concluded that the analysis tool proposed here makes it possible to compare students' knowledge structures and accordingly can provide insight into conceptual changes, relative to writing.

Abstract A model has been developed accurately predicting the temperature along a length of wire heated by passing a current through it. The wire is modeled as a transmission line with its thermal properties mapped onto the appropriate electronic analogs. A program describing the model circuit has been written in PSPICE such that time versus temperature curves can be generated for any wire given the material, diameter, length, and stressing current. The model has been dynamically temperature corrected, and its accuracy has been demonstrated for two types of fuses and one type of bond wire. This model is useful for predicting fusing conditions of fuse elements or bond wires, assessing the reliability of a material for given operating conditions (by knowing the temperature the material would attain), derating for design, and as a failure analysis tool by providing insight into an overstress condition in which a wire has melted open.

Insight Into

The purpose of this study was to examine the influence of manipulating game constraints on match performance in youth field hockey. A total of 25 participants aged 10.6–14.6 years old played four different 25-min games where density (228 m2 or 158 m2 per player) and/or number of players (11 per side or 8 per side) was manipulated. Match performance was determined by using notational analysis and physical demands were determined by using GPS analyses. Manipulating the number of players led to an increase in a successful passes (+2.68 passes), skilled actions (+3.73 skilled actions) and successful actions (+3.77 successful actions) performed per player and also created a more advantageous environment to enhance decision making. Increasing the density led to a decrease in unsuccessful dribbles (−0.59 unsuccessful dribbles) made by players and an increase in high intensity running (+38 m) and sprinting (+21.2 m). The findings of this study provide an insight into the effect of manipulating task constraints in skilled junior field hockey and the findings highlight that all types of constraints influence emergent performance in their unique way and that coaches should consider these interactions to promote specific playing behaviour.

Abstract In this paper, the passing ability of football players is determined by building three generalized additive mixed models that each explains a different aspect of a pass’ success: difficulty, risk and potential. The models are built on data from the 2014–2016 seasons of the Norwegian top division Eliteserien, and their predictive power is tested on the 2017 season. The results provide insight into the factors affecting the success of a pass in Eliteserien. These include the location of the pass, the relationship to previous passes and to situations such as throw-ins, corners, free kicks or tackles, as well as conditions specific to the Eliteserien, such as the time of season and the ground surface type. Finally, the key pass makers in the league are identified.
