Online Social Networking: Usage in Adolescents

Online social networking (OSN) has played a significant role on the relationship among college students. It is becoming a popular medium for socializing online and tools to facilitate friendship.   Young adults and adolescents are the most prolific users of OSN sites. The frequent use of OSN sites results in addiction toward these sites and simultaneously influence students’ daily life at large. The purpose of this study was to investigate the extent of usage of OSN sites by students of professional colleges in terms of duration and dependency and to find out the association of selected variables with OSN usage. A questionnaire was used to explore this issue and 350 college students participated in the survey. The findings revealed that most of the students logged in to OSN sites for more than 30 minutes a day and many of the students were dependent on these sites.

The effect of arm training on thermoregulatory responses and calf volume during upper body exercise

The final publication is available at Springer via https://doi.org/10.1007/s00421-014-2842-9.PURPOSE: The smaller muscle mass of the upper body compared to the lower body may elicit a smaller thermoregulatory stimulus during exercise and thus produce novel training-induced thermoregulatory adaptations. Therefore, the principal aim of the study was to examine the effect of arm training on thermoregulatory responses during submaximal exercise. METHODS: Thirteen healthy male participants (Mean ± SD age 27.8 ± 5.0 years, body mass 74.8 ± 9.5 kg) took part in 8 weeks of arm crank ergometry training. Thermoregulatory and calf blood flow responses were measured during 30 min of arm cranking at 60% peak power (W peak) pre-, and post-training and post-training at the same absolute intensity as pre-training. Core temperature and skin temperatures were measured, along with heat flow at the calf, thigh, upper arm and chest. Calf blood flow using venous occlusion plethysmography was performed pre- and post-exercise and calf volume was determined during exercise. RESULTS: The upper body training reduced aural temperature (0.1 ± 0.3 °C) and heat storage (0.3 ± 0.2 J g(-1)) at a given power output as a result of increased whole body sweating and heat flow. Arm crank training produced a smaller change in calf volume post-training at the same absolute exercise intensity (-1.2 ± 0.8% compared to -2.2 ± 0.9% pre-training; P < 0.05) suggesting reduced leg vasoconstriction. CONCLUSION: Training improved the main markers of aerobic fitness. However, the results of this study suggest arm crank training additionally elicits physiological responses specific to the lower body which may aid thermoregulation.Peer reviewedFinal Accepted Versio

Economic Policy-Making by Local Authorities in Britain and Western Germany (2nd ed)

Originally published in 1981 but now with a new preface, this volume provided the first detailed comparative analysis of how local authorities in the UK and W. Germany faced up to the challenge of trying to help local industry and improve employment prospects. Based on the results of case-studies the book considers the powers and resources available to local authorities and examines how the authorities are organized for this type of economic activity. The authors' analysis of the interplay of political and administrative factors will be particularly important for student and professionals in comparative public policy and public finance. The study shows how economic policy making in local government is constrained both by the higher levels of government in both countries and by the conditions in the economy operating both locally and nationally
