Developments in the biomechanics and equipment of Olympic cross-country skiers

2018

Source at: http://doi.org/10.3389/fphys.2018.00976 Here, our aim was to describe the major changes in cross-country (XC) skiing in recent decades, as well as potential future developments. XC skiing has been an Olympic event since the very first Winter Games in Chamonix, France, in 1924. Over the past decades, considerable developments in skiing techniques and improvements in equipment and track preparation have increased skiing speed. In contrast to the numerous investigations on the physiological determinants of successful performance, key biomechanical factors have been less explored. Today’s XC skier must master a wide range of speeds, terrains, and race distances and formats (e.g., dis…

Excessive Daytime Sleepiness in Obstructive Sleep Apnea Patients Treated With Continuous Positive Airway Pressure: Data From the European Sleep Apnea…

2021

Excessive daytime sleepiness (EDS) is a symptom of obstructive sleep apnea (OSA) that resolves under treatment with continuous positive airway pressure (CPAP). In some patients, sleepiness persists despite CPAP treatment. We retrospectively analyzed data on subjective residual EDS, assessed as an Epworth Sleepiness Scale score (ESS) >10, in patients from the European Sleep Apnea Database (n = 4,853, mean age +/- SD 54.8 +/- 11.8 years, 26.1% females), at baseline and at the first visit (median follow-up: 5 months, interquartile range 3-13). An ESS > 10 occurred in 56% of patients at baseline and in 28.2% of patients at follow-up. Residual EDS was analyzed in 2,190 patients (age: 55.1 +/- 12…

Friends, academic achievement, and school engagement during adolescence : A social network approach to peer influence and selection effects

2018

Abstract Peers become increasingly important socializing agents for academic behaviors and attitudes during adolescence. This study investigated peer influence and selection effects on adolescents' emotional (i.e., flow in schoolwork, school burnout, school value), cognitive (i.e., school effort), and behavioral (i.e., truancy) engagement in school. A social network approach was used to examine students of post-comprehensive education in Finland (N = 1419; mean age = 16). Students were asked to nominate peers to generate peer networks and to describe their own school engagement at two time points (one year apart). Network analyses revealed that the degree to which peer influence and selecti…

Mobile Apps and Social Media

2017

1The increasing penetration of smartphones among global population, especially among youth and children, has define a mobile and interactive media use without any precedent. A global connected world is the context in where our offspring are developing self-competences in media literacy because they manage technological devices at very early ages. This context is the state of affairs of this article in which we present two different steps: firstly, a theoretical study, showing the impact of mobile devices, focusing on smartphones and mobile applications where the question arisen is: What are children and young doing while online? Media literacy is also described in order to apply its dimensi…

Connecting others: Does a tertius iungens orientation shape the relationship between research networks and innovation?

2021

Research on social networks and innovation emphasizes that individuals spanning structural holes and crossing institutional boundaries have more opportunities for knowledge recombination and innovation involvement. However, transforming the potential knowledge and resources available through personal networks to attain innovation can be difficult for the focal individual. Using an ego-network approach, this study examines whether and to what extent an individual strategic orientation to cooperation (i.e. tertius iungens) contributes to strengthening the relation between two personal network properties (structural and institutional separation) and involvement in innovation. Our analysis is c…

The effect of early career social capital on long-term income development in Finland

2020

PurposeIn this study, the authors examine whether social capital embedded in individuals' social networks is connected to employees' long-term income development in Finland.Design/methodology/approachAnalyses are based on 25–35-year-old employees from the Finnish Living Conditions Survey of 1994 combined with register data on earned incomes from 1995 to 2016. The authors used questions addressing the frequency of meeting parents or siblings, spending free time with co-workers and participation in associational, civic or other societal activities as measures of the extent of network capital. Ordered logistic model was used to examine whether the size and composition of social networks differ…

Imagem corporal positiva e redes sociais na população adulta da área metropolitana de Buenos Aires

2021

Resumen: La imagen corporal positiva presenta una función protectora preeminente ante los medios de comunicación actuales, sin embargo, a la fecha no se cuenta con estudios que la vinculen con las redes sociales. El objetivo de este trabajo fue estudiar la asociación entre la motivación y usos de redes sociales y la imagen corporal positiva, considerando diferencias por sexo y grupos de edad. La muestra contó con 180 participantes, 94 varones (52.2 %) y 86 mujeres (47.8 %), edades de 18 a 65 años (M = 31.03; DE = 13.34).

Determinants of Prescription Opioid Use : Population‐Based Evidence from Finland

2021

Background and aims Previous studies have shown that prescription opioid use is more common in the socioeconomically disadvantaged communities in the US. This study examined the area and individual‐level determinants of prescription opioid use in Finland during the period 1995‐2016. Design Logistic regression analysis using nationwide data on filled opioid‐related prescriptions dispensed at Finnish pharmacies and covered by the National Health Insurance. Opioid consumption was linked, using personal identification codes, to population‐based data maintained by Statistics Finland, which records individual background and area‐level characteristics. Setting and participants Working‐age populati…
