This study explored in what way and to what extent people’s occupational position corresponds with the consumption of news and the exposure to political content offered by the traditional mass media TV, radio and newspaper. Empirical data from the ’Media use in the Netherlands, 2000’ survey among a representative sample of the Dutch population (Konig, et al., 2005) (N=825) were used. Occupation...

F the past decade, we have assessed the posture, hindlimb dynamics, and motor patterns for different forms of cat locomotion, including forward and backward walking 4 and slope walking. Two of our goals for undertaking these studies have been to identify the roles of muscle and inertial forces in the control of limb motion (reviewed in ref. 7) and to determine the mutability of motor patterns a...

When observers perceive several objects in a space, at the same time, they should effectively perceive their own position as a viewpoint. However, little is known about observers' percepts of their own spatial location based on the visual scene information viewed from them. Previous studies indicate that two distinct visual spatial processes exist in the locomotion situation: the egocentric pos...

The amplitude and mean power spectral frequency (MNF) of the electromyogram (EMG) of flexor digitorum superficialis and extensor carpi radialis muscles were monitored during cyclic, force-varying, constant-posture, submaximal, grip-force contractions until endurance. These contractions are reminiscent of work tasks associated with the risk of repetitive stress injuries. Based on recommendations...

OBJECTIVE To perform a retrospective radiographic evaluation on the fracture reduction and implant position in the femoral head among patients with pertrochanteric fractures who had been treated using a cephalomedullary nail in lateral decubitus; and to assess factors that might interfere with the quality of the fracture reduction and with the implant position in using this technique. METHODS...

PURPOSE To analyze multifocal ERGs (mfERGs) in patients with retinitis pigmentosa (RP), with constricted visual fields and visual acuity satisfactory for steady fixation. METHODS The mfERGs of 86 eyes of 43 patients with various forms of inheritance and durations of RP were analyzed. A retinal scanning system with a 20-in. monitor was used to map central cone function. Electrical signals of t...

The high demand for full polysomnography and the better quality of sleep at home are the main reasons for performing home sleep studies. Home respiratory monitoring has been evaluated in several studies, but the influence of setting on the results of unattended respiratory monitoring has not been assessed to date. Unattended monitoring of respiratory variables at home and in the sleep laborator...

The upright posture strengthens the coupling between heart period (HP) and systolic arterial pressure (SAP) consistently with a greater contribution of the arterial baroreflex to cardiac control, while paradoxically decreasing cardiac baroreflex sensitivity (cBRS). To investigate the physiological mechanisms that mediate the coupling between HP and SAP in response to different postures, we anal...

This study used stabilographic analysis to measure and describe changes in stability during standing in foals from birth to 5 months of age. Stabilographic analysis was performed on newborn foals immediately after first suckling then daily until 1 week of age, weekly until 1 month of age and monthly until 5 months of age. Ground reaction force (GRF) data were collected for periods of 8s with th...
