Little is known about the motivational forces leading retired individuals to engage in post-retirement activities and how they could be related to satisfaction with retirement. Using the self-determination framework, the purpose of the present exploratory study was to examine the nature of active retirees' motivation and its impact on satisfaction with life in retirement. The Global Motivation Scale and measures of satisfaction with retirement were administered to 150 active retired individuals engaged in organized post-retirement activities in a University-based organization. Results revealed that these individuals were mainly characterized by higher levels of intrinsic motivation for knowledge, stimulation and accomplishment, rather than extrinsic dimensions. Regression analysis further demonstrated that intrinsic motivation for both accomplishment and stimulation were positively related to satisfaction with retirement, over and above the significant contribution of time since retirement, anticipated satisfaction with retirement, and subjective health. This exploratory study highlights the motivational mechanisms through which post-retirement behaviors could positively influence satisfaction with life in retirement among active retirees.

This study focused on French and U.S. mother-infant dyads interacting in their homes. Infants' visual attention, tactual exploration, vocalization and mothers' mediated and unmediated stimulation and speech to infants were observed. Mothers and infants in the two cultures showed some similarities and some different emphases in their activities, and patterns of mother-infant interaction tended to correspond. (SH)

The development of the Rittershoffen deep geothermal field (Alsace, Upper Rhine Graben) between 2012 and 2014 induced unfelt seismicity with a local magnitude of less than 1.6. This seismicity occurred during two types of operations: (1) mud losses in the Muschelkalk formation during the drilling of both wells of the doublet and (2) thermal and hydraulic stimulations of the GRT-1 well. Seismicity was also observed 4 days after the main hydraulic stimulation, although no specific operation was performed. During chemical stimulation, however, no induced seismicity was detected. In the context of all field development operations and their injection parameters (flow rates, overpressures, volumes), we detail the occurrence or lack of seismicity, its magnitude distribution and its spatial distribution. The observations suggest the presence of the rock stress memory effect (Kaiser effect) of the geothermal reservoir as well as uncritically stressed zones connected to the GRT-1 well and/or rock cohesion. A reduction of the seismic rate concurrent with an increase of injectivity was noticed as well as the reactivation of a couple of faults, including the Rittershoffen fault, which was targeted by the wells. These results are derived from the homogeneous and consistent catalogue of more than 1300 local earthquakes that is provided. This reference catalogue is based on a standard detection method, whose output was manually verified and improved. The given absolute locations have been computed in a calibrated, geologically realistic 3D velocity model. Our work builds on previous analyses addressing the seismicity induced by the GRT-1 hydraulic stimulation and places the results into a historical context, thus considering the full dynamics of the observed phenomena. This paper also complements existing descriptions of the hydrothermal characteristics of the deep reservoir by providing insights separate from the wells. [ABSTRACT FROM AUTHOR]

Objectives: To compare the impact of virtual reality simulation training and theoretical teaching on the ability of inexperienced trainees to produce adequate virtual transvaginal ultrasound images., Methods: We conducted a randomized controlled trial with parallel groups. Participants included inexperienced residents starting a training program in Paris. The intervention consisted of 40 minutes of virtual reality simulation training using a haptic transvaginal simulator versus 40 minutes of conventional teaching including a conference with slides and videos and answers to the students' questions. The outcome was a 19-point image quality score calculated from a set of 4 images (sagittal and coronal views of the uterus and left and right ovaries) produced by trainees immediately after the intervention, using the same simulator on which a new virtual patient had been uploaded. Experts assessed the outcome on stored images, presented in a random order, 2 months after the trial was completed. They were blinded to group assignment. The hypothesis was an improved outcome in the intervention group. Randomization was 1 to 1., Results: The mean score was significantly greater in the simulation group (n = 16; mean score, 12; SEM, 0.8) than the control group (n = 18; mean score, 9; SEM, 1.0; P= .0302)., Conclusions: The quality of virtual vaginal images produced by inexperienced trainees was greater immediately after a single virtual reality simulation training session than after a single theoretical teaching session., (© 2015 by the American Institute of Ultrasound in Medicine.)
