Men's doubles professional tennis on hard courts: Game structure and point ending characteristics
2019
Despite the great tradition and importance of the doubles game in professional tennis, no literature has analysed to date the performance of professional players. Therefore, the information on the characteristics of the game, or the tactics related to how the points are won in doubles play is scarce. The objective of this study has been to describe the basic characteristics of the structure of the doubles game, and to establish how the points finish in doubles professional tennis played on hard courts. Thirty-four ATP doubles matches played in 2018 were analysed, which included a total of 40 professional players. As per the game structure, the results showed that, in comparison to the singl…
Intrinsic electrical conductivity of nanostructured metal-organic polymer chains
2012
One-dimensional conductive polymers are attractive materials because of their potential in flexible and transparent electronics. Despite years of research, on the macro- and nano-scale, structural disorder represents the major hurdle in achieving high conductivities. Here we report measurements of highly ordered metal-organic nanoribbons, whose intrinsic (defect-free) conductivity is found to be 104 S m−1, three orders of magnitude higher than that of our macroscopic crystals. This magnitude is preserved for distances as large as 300 nm. Above this length, the presence of structural defects (~ 0.5%) gives rise to an inter-fibre-mediated charge transport similar to that of macroscopic crysta…
Samtidskunst i skolen : En studie som inviterer elever til en konseptuell workshopspraksis
2019
Masteroppgave kunstfag KF500 - Universitetet i Agder 2019 Both from the elementary school education and the professional life, I have gained insight and an experience basis for commenting on the subject of arts and crafts. There are often techniques and crafts that are in focus.

The Playing Brain. The Impact of Video Games on Cognition and Behavior in Pediatric Age at the Time of Lockdown: A Systematic Review
2021
A growing number of children and adolescents play video games (VGs) for long amounts of time. The current outbreak of the Coronavirus pandemic has significantly reduced outdoor activities and direct interpersonal relationships. Therefore, a higher use of VGs can become the response to stress and fear of illness. VGs and their practical, academic, vocational and educational implications have become an issue of increasing interest for scholars, parents, teachers, pediatricians and youth public policy makers. The current systematic review aims to identify, in recent literature, the most relevant problems of the complex issue of playing VGs in children and adolescents in order to provide sugges…
A Playful Experiential Learning System With Educational Robotics
2020
This article reports on two studies that aimed to evaluate the effective impact of educational robotics in learning concepts related to Physics and Geography. The reported studies involved two courses from an upper secondary school and two courses from a lower secondary school. Upper secondary school classes studied topics of motion physics, and lower secondary school classes explored issues related to geography. In each grade, there was an “experimental group” that carried out their study using robotics and cooperative learning and a “control group” that studied the same concepts without robots. Students in both classes were subjected to tests before and after the robotics laboratory, to c…
Differences in Technical Development and Playing Space in Three UEFA Champions Leagues
2021
[Abstract] The analysis of football grows exponentially, with many researchers adopting it as an object of study. The thematic range that addresses it, as well as the different methodologies used, are of a very different nature—physical, psychological, technical, tactical—enriching every day the knowledge, and understanding of the game itself. The objective of this study has been to identify the differences between the different styles of play that lead to becoming the champion of the UEFA Champions League in the last 3 years of the pre-COVID stage, by analyzing the spatial performance developed, the association between the players that make up the different lines of the game system and the…
Pheromonal emission during the mating behavior ofEurycotis floridana (Walker) (Dictyoptera: Blattidae)
1996
The sexual behavior of males and females ofEurycotis floridana was investigated and the various associated behavioral sequences are described. Olfactometer data proved that the male produces a volatile sex pheromone attractive at a distance to conspecific females. The male initiates courtship behavior by exposing the glandular areas on the anterior parts of abdominal tergites 2, 7, and 8. This male calling behavior was observed throughout the day. The males can mate when 8 days old, whereas virgin females are sexually receptive 18 days after becoming adults. Once attracted near the male, the female opens her genital atrium and climbs on the back of the male, where she feeds on the glandular…
Testing the assumptions of conditional handicap theory: costs and condition dependence of a sexually selected trait
2000
Conditional handicap models of sexual selection predict that sexual traits are reliable signals of male quality because they are (a) condition dependent and (b) costly to produce or maintain. In this study, my objective was to experimentally investigate whether the drumming of male Hygrolycosa rubrofasciata wolf spiders is a condition-dependent costly trait. Males court females by drumming dry leaves with their abdomen and females preferentially mate with males drumming at higher rates. I manipulated male phenotypic condition and drumming rate simultaneously by keeping males on three different food rations and either introducing or not introducing them to a female. Food ration treatment aff…
Notostraca trackways in Permian playa environments of the Lodève basin (France).
2008
36 pages; International audience; For nearly 20 years, Dr. Lapeyrie, surgeon at Lodève, has gathered many fossils coming from the Salagou Formation of the Lodève Permian basin. They are Insects, Notostraca, plants and ichnofossils. Among the latter, appears a multitude of Arthropoda trackways, finely preserved, which were collected in the top of sequences deposited in a playa environment. The locomotion experiments undertaken with extant animals suggested allocation of the majority of these trackways to Notostraca which are also known by several hundreds of remains (carapace, appendages, body whole). From these different parts, it was described as Triops cancriformis permiensis and Lepiduru…
‘Whose were those feelings?’ : Affect and likenessing in Halat hisar live action role-playing game
2021
Halat hisar was a live action role-playing game (larp) organized in Finland in 2016. Halat hisar’s ambition as a larp was to mirror the current situation in Palestine. In larps, participants take on different roles and improvise without the presence of an audience. Larps offer a place where emotions and affectivities are transmitted through the embodiment of characters. Larps offer forms of likenessing, which create new affective states for the players. We conclude that larps can be powerful tools for portraying political alternatives of actual events, and they can serve a role in raising awareness. Larps offer a productive context for studying subjectivities where the focus is on affectiv…
