2. 1. On Business Exchange Activity : Activity Systems and Business Networks

   Author : Frans Prenkert; Håkan Håkansson; Lars Halén; Lars-Gunnar Mattsson; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business studies; Företagsekonomi; Business studies; Företagsekonomi;

   Abstract : Starting from an empirical study of a business firm’s problems with implementing an information system in its business activity, this thesis identifies a need to theoretically model and conceptually develop the general business activity of a firm. This puts the context in focus, as a well-functioning information system needs to be anchored and developed to support and enhance the activities for which it is used, that is, contextualized.

7. 5. Physical activity and the young female skeleton

   Author : Örnolfur Valdimarsson; Malmö Institutionen för kliniska vetenskaper; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; muskelsystem; reumatologi; Skelett; Skeleton; muscle system; rheumatology locomotion; Bone mass; Osteoporosis; Young female skeleton; Physical activity;

   Abstract : The aim of this thesis was to identify the influence of calcium, physical activity and detraining on bone mass and bone size in girls and young women. We hypothesised that calcium intake above a specific level does not enhance the accrual of bone mineral, that exercise predominantly influences the skeleton in the early pubertal period and that reduced training is followed by a loss of exercise-induced skeletal benefits.
