Observed Fitness May Affect Niche Overlap in Competing Species via Selective Social Information Use
2013
Social information transmission is important because it enables horizontal spread of behaviors, not only between conspecifics but also between individuals of different species. Because interspecific social information use is expected to take place among species with similar resource needs, it may have major consequences for the emergence of local adaptations, resource sharing, and community organization. Social information use is expected to be selective, but the conditions promoting it in an interspecific context are not well known. Here, we experimentally test whether pied flycatchers (Ficedula hypoleuca) use the clutch size of great tits (Parus major) in determining the quality of the ob…
Competitive Anxiety and Psychological Well-being: the Role of Coping Strategies
2015
Resumen:El interés por el estudio del bienestar psicológico (Ryff, 1989) y su relación con las estrategias de afrontamiento se ha producido también en el ámbito deportivo. En esta investigación, se evalúan la ansiedad competitiva, el bienestar psicológico y las estrategias de afrontamiento utilizadas en la competición por 213 deportistas, de cuatro deportes diferentes. Los resultados permiten predecir, a través de los análisis de regresión, la posibilidad de experimentar ansiedad y bienestar psicológico en el contexto competitivo, regulado por el papel mediador de las estrategias de afrontamiento dirigidas a la tarea. Abstract:Interest in the study of psychological well-being (Ryff, 1989) a…
Effects of Rule Changes on Game-Related Statistics in Men's Water Polo Matches
2017
The aim of this study was to investigate the effects of rule changes on game-related statistics in men's water polo matches. A total of 856 men's matches played in all Olympic Games and World Championship since 1936 was analysed. The game-related statistics considered were: total goals, winners' goals, losers' goals, goals per minute, goals difference, relationship difference goals and total goals, and relationship difference goals and winners' goals. The rule changes were grouped by structural (game and period) and functional changes (possession time, exclusion time, timing, minimum distance to take a direct shot). Differences between rule changes were determined using a one-way ANOVA. In …

MEASURES FOR STIMULATING COMPETITION ON MOBILE SERVICES MARKET IN ROMANIA TO MAXIMIZE BENEFITS FOR END USERS
2010
In the last years, the market of mobile services in Romania had a huge success; the number of users of this type of services is constantly growing. The interest of the investors who were encouraged by statistics and have recently appeared on the market shows that Romanians are leaders in mobile services and that people are very attached to their mobile devices. ANCOM – the National Authority for Administration and Regulation in Communications) is the institution governing the mobile services market in Romania which establishes the rules and ensures that the market players comply with these regulations. Its mission is to ensure arbitrage on the communications market and genuine competition f…
La nuisibilité directe des adventices en grandes cultures : quelles réponses nous apportent les essais désherbages ?
2016
The direct harmful effect of weeds in field crops : what do herbicide trials tell us ? Weeds are plants whose undesirable qualities (“harmfulness") outweigh their desirable qualities (trophic resources). Few studies conclude that weeds do not affect crop yield. However, it is difficult to generalize since weeds compete with crops for resources and these resources are spatially and temporally variable. This study analyzed 110 herbicide trials (untreated vs. treated plots) performed in France from 1993 to 2015 on three major grain crops: winter wheat, winter oilseed rape and sunflower. Significant yield losses were found in 92% of wheat trials (average over all trials: -2.6 t/ha), 51% of wint…
THE RELATIONSHIP BETWEEN WOMEN´S ARTISTIC GYMNASTICS TECHNICAL SKILL, PHYSICAL PERFORMANCE TEST RESULTS AND SUCCESS IN COMPETITIONS IN FINLAND
2019
The aim of this study was to find out the potential of the Minoritest to identify the most likely talented gymnasts to join the national team pre-training group in Finland. The study examined the relationships between gymnasts´ (N=215, age 10–13) Minoritest results (2006–2010) and success in competitions after the Minoritests until the end of 2016. The competition results were also compared between the gymnasts who had participated in the test and a random number (N=180) of gymnasts who had not. According to this study, the majority (92%) of the best gymnasts in competitions had participated in the Minoritest. 39% of the best in competitions were among the top 10 in the Minoritest. The test…
Circular economy and environmental protection
2022
<abstract> <p>The circular economy represents a form of corporate production with respect to environmental resources. In the past, these production systems were widespread on the basis of the non-removability of the production factors. The advent of economic growth, in capitalist economies, has led to the deconstruction of production cycles resulting to a food product being produced in one part of the world, whilst the raw materials and processing phases are carried out in several parts of the world, due to the low production costs there. While these economic systems, on the one hand, have led to a growth in the global economic system, on the other hand they have determined the …
E-NAUTILUS: A decision support system for complex multiobjective optimization problems based on the NAUTILUS method
2015
Interactive multiobjective optimization methods cannot necessarily be easily used when (industrial) multiobjective optimization problems are involved. There are at least two important factors to be considered with any interactive method: computationally expensive functions and aspects of human behavior. In this paper, we propose a method based on the existing NAUTILUS method and call it the Enhanced NAUTILUS (E-NAUTILUS) method. This method borrows the motivation of NAUTILUS along with the human aspects related to avoiding trading-off and anchoring bias and extends its applicability for computationally expensive multiobjective optimization problems. In the E-NAUTILUS method, a set of Pareto…
Human-technology choreographies
2014
Bodily movements have traditionally had mostly instrumental value in interaction design. However, movements can also be given a central role in understanding behaviour and in designing technology for humans. This workshop is aiming at taking a fresh, movement-oriented look at the design and evaluation of technology in a wide variety of contexts.
