    joystick operators during the use of a commonly used North American hydraulic actuation joystick The six different experimental conditions included combinations of three joystick stiffnesses and two movement speeds The highest instantaneous input torque over the course of the joystick movement not including the hard endpoint was evaluated using the peak torque value Angular impulse provided an indication of the sustained exposure to force The third indicator deceleration at the hard endpoint was included to provide a description of impact loading on the hand as the joystick came to a sudden stop The most important result of this work is that the dynamic torque characteristics incurred during hydraulic actuation joystick use are substantial While the peak torque values were not very different between the fast and slow motion conditions the high decelerations even for slow movements observed at maximum excursion of the joystick indicate that the dynamics do matter On the basis of deceleration at the hard endpoint and peak torque the joystick movements that require the highest values for a combination of torque variables are the side to side ones This suggests that less stiff balance and return springs should be considered for these directions than for forward and backward movements However if the design does not minimize acceleration it is important that the spring stiffness not be too low since deceleration at the joystick hard endpoint will be very high causing the operator to incur large palm and finger impacts Bookmark by Jeremy Rickards 13 Psychology Ergonomics Humans Movement Bilateral isokinetic training reduces the bilateral leg strength deficit for both old and young adults The bilateral limb deficit BLD describes the difference in maximal or near maximal force generating capacity of muscles when they are contracted alone and in combination with the contralateral muscles This study examined the effects of more The bilateral limb deficit BLD describes the difference in maximal or near maximal force generating capacity of muscles when they are contracted alone and in combination with the contralateral muscles This study examined the effects of a 6 week three times per week bilateral leg strength training programme on BLD in younger and older adults Data were collected from 33 subjects during slow 45 degrees s isokinetic knee extensions and flexions before and after the training programme After training the BLD was reduced for extension 73 3 86 9 P amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp lt 0 001 but not for flexion 67 5 71 2 P 0 13 regardless of age and gender This study suggests that difficulty in recruiting all muscle units during a task involving bilateral activation can be improved by training although such an effect appears to depend on the muscle group appreciated Bookmark by Jeremy Rickards and 2 Usha Kuruganti Poulain P 20 Skeletal muscle biology Aging Adolescent Humans The role of human factors engineering in establishing occupational fitness standards ABSTRACT Human factors engineering HFE is the study of the impact of

    The predominance of scale effects cause aggregate SO2 and CO2 levels to increase with GNP in the early stages of development Then in the case of SO 2 technique and regulation effects may be the cause of falling SO2 levels with continued economic growth establishing the EKC CO2 continues to monotonically increase as output levels increase over time The positive relationship may be due to the lack of regulations on this pollutant If stricter regulation policies were instituted in the two case studies an improved allocation of resources may result While GNP may be 2 596 to 20 lower than what has been realized in the US economy depending on the pollution variable analyzed individual welfare may increase from lower pollution levels Bookmark by Van Lantz Is there an Environmental Kuznets Curve for clearcutting in Canadian forests Bookmark by Van Lantz Testing the Environmental Kuznets Curve Hypothesis with Bird Populations as Habitat Specific Environmental Indicators Evidence from Canada Abstract The traditional environmental Kuznets curve EKC hypothesis postulates that environmental degradation follows an inverted U shaped relationship with gross domestic product GDP per capita We tested the EKC hypothesis with more Abstract The traditional environmental Kuznets curve EKC hypothesis postulates that environmental degradation follows an inverted U shaped relationship with gross domestic product GDP per capita We tested the EKC hypothesis with bird populations in 5 different habitats as environmental quality indicators Because birds are considered environmental goods for them the EKC hypothesis would instead be associated with a U shaped relationship between bird populations and GDP per capita In keeping with the literature we included other variables in the analysis namely human population density and time index variables the latter variable captured the impact of persistent and exogenous climate and or policy changes on bird populations over time Using data from 9 Canadian provinces gathered over 37 years we used a generalized least squares regression for each bird habitat type which accounted for the panel structure of the data the cross sectional dependence across provinces in the residuals heteroskedasticity and fixed or random effect specifications of the models We found evidence that supports the EKC hypothesis for 3 of the 5 bird population habitat types In addition the relationship between human population density and the different bird populations varied which emphasizes the complex nature of the impact that human populations have on the environment The relationship between the time index variable and the different bird populations also varied which indicates there are other persistent and significant influences on bird populations over time Overall our EKC results were consistent with those found for threatened bird species indicating that economic prosperity does indeed act to benefit some bird populations Resumen La hipótesis de la curva ambiental Kuznets CAK postula que la degradación ambiental tiene una relación en forma de U invertida con el producto doméstico bruto PDB per cápita Probamos la hipótesis CAK con poblaciones de aves como indicadores de la calidad ambiental en 5 hábitats diferentes Debido a que las aves
