1984 Is Still Fiction: Electronic Monitoring in the Workplace and U.S. Privacy Law

Electronic monitoring in the workplace has been the subject of relentless public criticism. Privacy advocates argue that technological advancements have given overbearing employers powerful tools to abuse employee dignity in the name of productivity and that new legislation should bolster workplace privacy rights. This iBrief contends that current U.S. legal doctrine governing electronic monitoring in the workplace is fair given the nature and purpose of the workplace, and potential employer liability for employee misconduct

The measurement of scatter and absorption using three spectrophotometric techniques

Three methods for scattering and absorption measurements were compared for correlation; Kubelka-Munk, 4pi and an in transmission compartment scattering measurement method. The results indicated highest correlation between the 4pi and Kubelka-Munk absorption measurements. The 4pi and Kubelka-Munk scattering measurements had the highest correlation for scattering, and almost no correlation was found between Kubelka-Munk and in transmission compartment scattering measurements

Muscle Damage following Maximal Eccentric Knee Extensions in Males and Females

Aim: To investigate whether there is a sex difference in exercise induced muscle damage. Materials and Method: Vastus Lateralis and patella tendon properties were measured in males and females using ultrasonography. During maximal voluntary eccentric knee extensions (12 reps x 6 sets), Vastus Lateralis fascicle lengthening and maximal voluntary eccentric knee extensions torque were recorded every 10° of knee joint angle (20–90°). Isometric torque, Creatine Kinase and muscle soreness were measured pre, post, 48, 96 and 168 hours post damage as markers of exercise induced muscle damage. Results: Patella tendon stiffness and Vastus Lateralis fascicle lengthening were significantly higher in males compared to females (p0.05). Creatine Kinase levels post exercise induced muscle damage were higher in males compared to females (p<0.05), and remained higher when maximal voluntary eccentric knee extension torque, relative to estimated quadriceps anatomical cross sectional area, was taken as a covariate (p<0.05). Conclusion: Based on isometric torque loss, there is no sex difference in exercise induced muscle damage. The higher Creatine Kinase in males could not be explained by differences in maximal voluntary eccentric knee extension torque, Vastus Lateralis fascicle lengthening and patella tendon stiffness. Further research is required to understand the significant sex differences in Creatine Kinase levels following exercise induced muscle damage

Projectile penetration of thin aluminium plate

The study of thin plate penetration has long been hampered by the lack of experimental data and that which has been reported is concerned mainly with displacement time records of the projectile and target responses to impact. In the present study two new techniques have been developed to monitor: the penetration process. The first records a specific particle deceleration in the projectile during penetration from which the forces of impact can be derived and the second records the growth of the projectile target contact area. Whereas data obtained from the first method can only describe the projectile's response to impact, it is possible by means of the second method to interrelate the projectile and target responses. The combination of these two techniques therefore provides a powerful tool by which thin plate impacts can be studied. To understand the nature of the experimental results which have been obtained, an empirical model of thin plate penetration has been developed. This analysis is based on the assumption that on impact, the target responds as a thin rigid plastic membrane and has been found to model the penetration process reasonably well for D/H ratios greater than 10
