A comparison of men's and women's strength to body mass ratio and varus/valgus knee angle during jump landings

The purpose of this investigation was to compare valgus/varus knee angles during various jumps and lower body strength between males and females relative to body mass. Seventeen recreationally active females (age: 21.94 ± 2.59 years; height: 1.67 ± 0.05 m; mass: 64.42 ± 8.39 kg; percent body fat: 26.89 ± 6.26%; squat one-repetition maximum: 66.18 ± 19.47 kg; squat to body mass ratio: 1.03 ± 0.28) and 13 recreationally active males (age: 21.69 ± 1.65 years; height: 1.77 ± 0.07 m; mass: 72.39 ± 9.23 kg; percent body fat: 13.15 ± 5.18%; squat one-repetition maximum: 115.77 ± 30.40 kg; squat to body mass ratio: 1.59 ± 0.31) performed a one-repetition maximum in the squat and three of each of the following jumps: countermovement jump, 30 cm drop jump, 45 cm drop jump, and 60 cm drop jump. Knee angles were analysed using videography and body composition was analysed by dual-energy X-ray absorptiometry to allow for squat to body mass ratio and squat to fat free mass ratio to be calculated. Significant differences (P ≤ 0.05) were found between male and female one-repetition maximum, male and female squat to body mass ratio, and male and female squat to fat free mass ratio. Significant differences were found between male and female varus/valgus knee positions during maximum flexion of the right and left leg in the countermovement jump, drop jump from 30 cm, drop jump from 45 cm, and drop jump from 60 cm. Correlations between varus/valgus knee angles and squat to body mass ratio for all jumps displayed moderate, non-significant relationships (countermovement jump: r = 0.445; drop jump from 30 cm: r = 0.448; drop jump from 45 cm: r = 0.449; drop jump from 60 cm: r = 0.439). In conclusion, males and females have significantly different lower body strength and varus/valgus knee position when landing from jumps.     

Problem Interpretation and Resolution via Visual Stimuli: The Use of ‘Mood Boards’ in Design Education

This paper defines and discusses ‘mood boards’– those assemblages of images and, less frequently, objects, which are used to assist analysis, creativity and idea development in design activity. There is need for discussion since little published information currently exists to guide students and tutors. The paper proposes that mood boards can assist problem finding as well as problem solving. Primarily, mood boards provide a mechanism for students and practising designers to respond to perceptions about the brief, the problem as it emerges and the ideas as they develop. The construction of mood boards potentially stimulates the perception and interpretation of more ephemeral phenomena such as colour, texture, form, image and status. They are, like Debono's lateral thinking techniques, partly responses to an inner dialogue and partly provocation to become engaged in such a dialogue. Examples are drawn from recent work in the field of industrial design at Loughborough University.     

Googled: the quest for visibility on the Internet

Small publishing‐related firms have a problem getting their services and products known to the scholarly and STM market. Getting listed on search engine results pages is difficult due to the way the most popular search engines rank sites. Galayaa has tried out Google's AdWords as a way to get noticed. Does it work? An impression of early results of the campaign is given.
