Bedre trafikkultur via målinger af passage afstande mellem køretøjer og cyklister

Ved brug af ultralyds baseret måler og video kamera monteret på cykel, er der foretaget 1.374 målinger af passage afstande mellem køretøjer og cyklist. Disse målinger er ud fra video af passager suppleret med oplysninger om køretøj, dets størrelse og fart samt forhold omkring vejens beskaffenhed og den øvrige trafik. Analyse af data viser bl.a., at middelværdien for passage afstand reduceres fra 175 til 135 cm ved modkommende trafik; at pang-farvet cykeljakke reducerer afstand med 10 cm; at afstanden er mindst i eftermiddags myldretid og størst i aftentimer, og at der ikke er forskelle i middelværdier mellem personbiler, varevogne/gulpladebiler, lastbiler og busser. Efterhånden som datagrundlag etableres, udnyttes disse data til at igangsætte en debat og dermed øget fokus om passage afstande. Målet er at gøre bilister mere opmærksomme på at passere med en tryghedsskabende afstand. Samtidig er forventningen også, at dokumentation af, at den faktiske afstand er noget større end den oplevede (alt for tæt på) afstand, kan bruges til at øge tryghedsfølelsen blandt cyklister

Recreational football for disease prevention and treatment in untrained men: a narrative review examining cardiovascular health, lipid profile, body composition, muscle strength and functional capacity

Over the past 10 years, researchers have studied the effects of recreational football training as a health-promoting activity for participants across the lifespan. This has important public health implications as over 400 million people play football annually. Results from the first randomised controlled trial, published in the BJSM in January 2009, showed that football increased maximal oxygen uptake and muscle and bone mass, and lowered fat percentage and blood pressure, in untrained men, and since then more than 70 articles about football for health have been published, including publications in two supplements of the Scandinavian Journal of Medicine and Science in Sports in 2010 and 2014, prior to the FIFA World Cup tournaments in South Africa and Brazil. While studies of football training effects have also been performed in women and children, this article reviews the current evidence linking recreational football training with favourable effects in the prevention and treatment of disease in adult men

Breadth and Depth of Promotional Sales in Food Retailing

Temporary price reductions (sales) as a means of promotion have become an increasingly important tool in the marketing mix of food retailers around the world. This paper investigates the retailers' pricing strategy by explicitly accounting for the multi-product nature of retailing. We find that retailers systematically adjust the breadth and depth of sales over time and they respond aggressively to their rivals' promotional activities. Finally, the breadth and depth of sales are found to be substitutes in the set of the available strategies to increase the store traffic. (authors' abstract
