Agile software development and service science

This paper shows the necessary steps, which should be taken in order to get the most out of agile software development in interdisciplinary settings involving scientific experts. If applied properly, Agile delivers increased productivity, higher quality and, last but not least, higher customer satisfaction. The task of developing high quality software is already difficult. Developing software for a new IT-enabled service in an interdisciplinary team however, is even more challenging. In interdisciplinary projects scientific experts from different fields need to work together with computer scientists, developers, testers, business analysts and domain experts. Software engineering is very time-consuming and scientific experts who have never been involved in a software project, often find it hard to understand why progress sometimes seems so slow. Therefore, it is important that they understand what it takes to write high- quality code, i.e. code that is clean, tested, documented and extendable at the right points. The best way to achieve this goal is to expand the software team, make the scientific experts an integral part of it and thus profit from their know-how

Current status and future challenges in psychological research of sport injury prediction and prevention : a methodological perspective

The purpose of this critical review was to propose methodological developments in sport injury prediction and prevention research. Altogether, 24 studies (e.g., quantitative, qualitative, and prevention intervention studies) conducted from 2006 forward were analysed, related to the "stress-injury model." The injury prediction studies were mostly based on prospective designs, using regression analysis, and studied trait anxiety and life stress. The qualitative studies used mainly thematic analysis, and the intervention studies showed some promising effects, but also inconclusive results. We proposed five specific needs for future research: (a) focus on separate research cohorts, (b) variation in preventive intervention designs, including sound protocols conducting experimental studies, (c) focus on behaviours in relation to cognition, (d) application of repeated-measure designs, and (e) use of statistics that could test complex interactions and intraindividual differences. Future research attention should also be oriented towards the psychology of overuse injuries, biopsychosocial perspectives, and health economic evaluations. While progress has been made in research on psychological antecedents of sport injury, prevention, and intervention in the last 10-15 years, several methodological issues still remain to be further developed, as outlined in this article.El propósito de esta revisión crítica es proponer una serie de progresos metodológicos en la investigación sobre predicción y prevención de lesiones. Para ello, se analizaron conjuntamente 24 estudios (cuantitativos, cualitativos y de intervención preventiva) llevados a cabo desde el año 2006 en adelante relacionados con el "modelo de estrés-lesión". Los estudios de predicción de lesiones utilizaron mayoritariamente diseños prospectivos, utilizando el análisis de regresión y estudiando el rasgo ansiedad y los eventos vitales. Los estudios cualitativos utilizaron principalmente el análisis temático. Los estudios de intervención mostraron resultados promisorios, aunque todavía no definitivos. En este trabajo proponemos cinco necesidades específicas para la investigación futura: (a) centrarse en diferentes cohortes, (b) variar los diseños de intervención preventiva, incluyendo protocolos experimentales, (c) centrarse en las conductas relacionadas con las cogniciones, (d) utilización de diseños de medidas repetidas, y (e) utilización de estadísticos que puedan verificar las complejas interacciones y las diferencias individuales. El foco de la investigación futura también debe orientarse hacia la psicología de las lesiones por desgaste excesivo, las perspectivas biopsicosociales y las evaluaciones económicas del impacto en la salud. Si bien en los últimos 10-15 años se han conseguido importantes avances en la investigación sobre los antecedentes psicológicos de la lesión deportiva, la prevención y la intervención, algunas cuestiones metodológicas deben ser aún desarrolladas, tal y como se señala en este artículo.O objectivo desta revisão crítica é propor uma série de progressos metodológicos na investigação sobre a predição e prevenção de lesões.

Need-supportiveness and athlete well-being: Coaches' competence-support at risk in the elite sport context throughout the season

The aim of this study was to explore how coaches’ behaviour affected athletes’ well-being by examine: (a) the potential change in perceptions of need-support from the coach (over an academic year), and (b) the within-person relationship between the three aspects of need-supportiveness and subjective vitality at the end of the winter sport season. 102 youth elite student athletes completed ta questionnaire three times. Bayesian growth curve analyses showed that the levels of relatedness and autonomy support were stable and high throughout the year. In contrast, competence support decreased during the season. In addition, the results showed a credible positive within-person relationship between changes in all three facets of need-supportiveness from the coach and vitality measured at the end of the season which support SDT tenets. These findings indicate the importance of need-support for athletes' wellbeing, and that competence support needs extra attention in the elite sport context where the competence need is constantly challenged

Common demanding conditions among professional high-level military and sport leaders: a cross-contextual qualitative reflexive thematic analysis

Military and sport have attracted increased research interest separately as two distinctly demanding performance- and leadership-driven contexts. However, cross-contextual psychological research in leadership is lacking. Such research has potential to expose unique cross-fertilising insights into resemblances in leadership challenges among military and sport leaders, transferable to a broader range of contexts. Thus, the current study simultaneously explored high-level military and sport leaders’ real-life experiences of similarities in demanding conditions and their psychological manifestations. Sixteen participants - eight Swedish high-level military leaders and eight Swedish high-level sport leaders, participated in the study. Using a qualitative inductive cross-contextual design enabled in-depth knowledge and transferability. A reflexive thematic analysis (RTA) of sixteen interview transcripts generated four common themes of demanding conditions: (1) Developing organisations: Leading under an extensive workload and responsibility, (2) Managing destructive superiors and subordinates: Standing up for oneself, (3) Taking care of the minds and moods of others: Leading deliberated difficult conversations, and (4) Periods of extreme concentration: Leading critical coordination, decisions, and timing. The findings tie high-level military and sports leaders together into a high-stress and high-stakes leader role invoked to manoeuvre a complex buildup of demanding conditions. Implications are presented. Keywords: High-level leaders, military, sport, demanding conditions

However, it is important to be regularly physically active to obtain these effects. Using the motivational lens of self-determination theory, the aim of the current study was to explore the dynamic interplay between satisfaction of psychological needs (autonomy, competence, relatedness) in PA and the patients’ weekly PA level. Methods: The study had a longitudinal design, following 10 in-patients with dual diagnoses (SMI and addiction) over 12 weeks at a psychiatric ward offering physical activity as part of treatment. Data were collected 14 times with a questionnaire measuring psychological need satisfaction, while an accelerometer was used to objectively count steps to reflect participants average PA-level each week. To analyse the week-to-week relationships between the basic psychological needs and PA-level, the Bayesian dynamic p-technique analysis was used to explore both cross-sectional-, autoregressive- as well as cross-lagged effects between the constructs. Results: The results indicated credible and strong positive autoregressive effects for all three psychological needs as well as for PA-level, and positive credible cross-sectional associations between all three psychological needs and PA-level. However, the cross-lagged effects were small and not credible for all three psychological needs in relation to PA-level. Conclusions: In total, these results support the established positive relation between basic psychological need satisfaction and PA-level yet failed in finding any predictive effects between need satisfaction and PA-level.publishedVersio

Are the playoffs different from the regular season? A comparison of in-game statistics in Icelandic elite handball

There are many axioms in sport that are taken at face value. One of them is that the playoffs are somehow totally different from the regular season. The aim of this study was to test that axiom by comparing in-game statistics during the regular season and the playoffs in the semi-professional Icelandic elite men’s handball league. Data from 724 games (648 regular season games and 76 playoff games; 1448 data points) across five seasons were analysed using a two-level logistic regression analysis. The variables of interest were pace, fast breaks, legal stops, penalty throws given, 2-minute suspensions, and saves. The results indicated no meaningful differences in fast breaks, penalty throws given or number of saves, but did find signs of added intensity during the playoffs with a higher pace, more legal stops and more 2-minute suspensions. While the differences were not particularly large, they have the possibility of being practically meaningful and were in line with the axiom. Possible explanations were discussed but more research is needed to determine whether these findings are context- or sport-specific.publishedVersio

Öppna dagvattensystem

Nybyggnationen i Helsingborg Ångfärjetomten är under planering. En ny central mötesplats vid kajområdet i centrala Helsingborg ska göra staden mer attraktiv och främja både näringsliv och turism. Föreliggande studie presenterar förslag för hur Helsingborg stad kan använda sig av öppna dagvattensystem för att ta hand om dagvattnet på platsen. Med en fördjupad kunskap kring öppna dagvattensystem har författarna efter en litterär studie applicera deras kunskaper i praktiken. För platsen utvalda dagvattensystem försöker de kombinera olika systemen på ett sätt så att vattnet i så stor utsträckning som möjligt har chans att påverkas av öppna dagvattensystems positiva egenskaper. När idéplanen och projektering står klar får författarna chans att ta ett steg tillbaka och titta opartiskt på deras förslag om öppna dagvattensystem. Detta ger dem chansen att reflektera kring deras val och möjlighet att ställa frågor som: Kan man motivera öppna dagvattensystem vid ny exploatering i urban miljö

Simulated Game-Based Ice Hockey Match Design (Scrimmage) Elicits Greater Intensity in External Load Parameters Compared With Official Matches

Objective: A limited number of studies have explored the external load experienced in indoor sports such as ice hockey, and few the link between training and match performance. As a paucity exists within this topic, this study explored whether a simulated match design (i.e., scrimmage) could be representative of official match demands and elicit similar external loads as in official matches in a group of elite youth male ice hockey players. Methods: A total of 26 players were monitored during eight official and four simulation matches using a Local Positioning System. Total distance, max velocity, slow (0–10.9 km/h), moderate (11–16.9 km/h), high (17.0–23.9 km/h), and sprint (>24 km/h) speed skating distance, distance per min, PlayerLoadTM, PlayerLoadTM per min, high-intensity events (HIEs) (>2.5 m/s−2), acceleration (ACCs), decelerations (DECs), and change of directions (CODs) were extracted from the tracking devices. A two-level regression analysis was conducted to compare the difference between match types when controlling for time on ice, match day, and position. Results: Between match-type results showed a credible difference in all variables except max velocity and ACCs. Distance per min was 27.3% higher during simulation matches and was explained by a 21.3, 24.1, and 14.8% higher distance in sprint-, high-, and moderate speed skating distance, while slow speed-skating distance was 49.2% lower and total distance only trivially different from official to simulation matches. Total PlayerLoadTM was 11.2% lower, while PlayerLoadTM per min was 8.5% higher during simulation matches. HIEs, CODs, and DECs were 10.0, 11.9, and 22.3% higher during simulation matches. Conclusion: The simulated match design is related to official match demands with comparable match-time, playing time, number of shifts, and shift duration. However, simulation matches provoked a higher external load output compared with official matches, possibly explained by a more continuous movement design. A game-based simulation match design can therefore be utilized when match-related actions at high intensity are warranted.publishedVersio
