Background To systematically analyse evidence on the incremental effect of work-related psychosocial risk factors on the development of neck and shoulder disorders, as reported in longitudinal studies. Methods A systematic literature search was conducted in three data bases (MEDLINE, EMBASE, and PsychINFO) until May 2009. The quality assessment leading to a methodological quality score of the included studies was conducted by two independent reviewers using a standardised checklist. Criteria for the evaluation of evidence were established. Heterogeneity analyses were conducted. Results Altogether 18 prospective longitudinal studies were included in the analysis. Potential psychosocial risk factors were mainly based on the job demand control (support) model by Karasek (1998). Study results were too heterogeneous to deduce pooled risk estimates. But the weight of evidence was strong for an incremental effect of job demands, job control, social support, and job strain, on the development of neck and/or shoulder disorders. Conclusion While we found evidence for an incremental effect of different psychosocial work factors (in addition to the effect of physical job factors), these results have to be interpreted carefully in order to support the notion that psychological factors can have an independent causal influence on the development of musculoskeletal disorders. Nevertheless, our findings are important for the development of preventive strategies, as they stress the need for preventive approaches that tackle both physical and psychosocial factors. Future research is warranted to consolidate and strengthen the results of this review. © Springer-Verlag 2012.

Purpose: To identify factors associated with satisfaction among patients receiving ophthalmic services and to indicate the intensity of this relationship. Methods: The data used was obtained through a self-administered, post-visit questionnaire from randomly selected 507 patients treated in seven eye clinics in Germany. The instrument assessed satisfaction with several aspects of care and patient baseline and visit characteristics. Bivariate and multivariate techniques were used to reveal relations between indicators and overall satisfaction. Results: Factor analysis yielded two factors, 'medical aspects of care' and 'performance of service', explaining 55% of total variance. Cronbach's α coefficient for both scales indicates acceptable internal consistency. Bivariate analysis showed strong relations between overall satisfaction and perceived care with weaker findings pertaining to visit characteristics. Not any of the demographic variables was associated with overall satisfaction. Perceived length of stay, intention to return to the clinic, and occurrence of complications were influential attributes on satisfaction ratings. The multivariate analysis identified seven factors associated with overall satisfaction including the treatment outcome (OR: 4.57), kindness of the nurses (OR: 5.27) and medical practitioners (OR: 2.23), room amenities (OR: 2.72), organization of procedures and operations (OR: 2.71), information about anaesthesia (OR: 1.95), and cleanliness (OR: 1.93). Conclusions: Factors associated with patient satisfaction in ophthalmology concern medical aspects like the organization of procedures and operations but also aspects that are not directly related to technical care, such as kindness of the nurses and cleanliness. Results show that patients' subjective experiences of received care and services relate more strongly and consistently to overall satisfaction than patient demographic data or visit characteristics. Revealed factors predicting patient satisfaction are alterable by health care managers. Therefore, focusing on these attributes represents an effective manner to enhance patient satisfaction in ophthalmology. © 2011 The College of Optometrists.

This letter reports the first experimental observation, to our knowledge, of optical vector solitons composed of two incoherently coupled vortex components. We employ nematic liquid crystal to generate stable vector solitons with counterrotating vortices and hidden vorticity. In contrast, the solitons with explicit vorticity and corotating vortex components show azimuthal splitting. © 2012 Optical Society of America.

Road design by highway planning authorities and planning offices is performed at three separate levels: the horizontal and the vertical projections and the cross section. Experiments have shown that shortcomings in the three-dimensional (3-D) alignment may still occur when these three levels are processed separately and then superimposed. It makes sense to calculate virtual perspective views and special control parameters with the use of visualization tools and then to check the 3-D alignment with those tools. Shortcomings of this kind can cause accidents, particularly on two-lane rural roads. Unified model assumptions that match the driver's vision must be set to ensure the comparability of the central perspective views. Drivers absorb images from a central perspective when driving along a road. A driver's inability to recognize a section of the road in the driving area ahead gives rise to blind sections. Designers need to use standard 3-D elements as much possible. These shortcomings are of two major types: those that are safety related and those that are merely aesthetic. A methodology has been developed to check the 3-D alignment for shortcomings in the three basic stages (checking for standard 3-D elements, safety-related shortcomings, and aesthetic shortcomings). By using the visualization tool VISS ALL 3D, the design engineer can calculate the virtual perspective views with the safety-related shortcomings and illustrate them in the blind-section graph. Shortcomings in the 3-D alignment must be eliminated at the end of the redesign process.

Objective: To identify key determinants of patient satisfaction. Design: Data used were obtained through a self-administered, post-visit questionnaire by random sampling during the period of January 2009 to September 2009. Setting: Thirty-nine hospitals in Germany. Participants: A total of 8428 patients. Main Outcome Measure: Global patient satisfaction was measured by a single item question. Attributes of medical aspects of care were measured using 12 items, performance of service using 3 items and different dimensions of patient expectations using 12 items. Medical aspects of care and performance of service items were entered into logistic regression analysis to identify determinants of patient satisfaction. Results: The results of the analysis showed that there are 10 determinants of global patient satisfaction. The outcome of treatment was overall, the most salient predictor followed by nursing kindness as the second most important component. Items reflecting information receiving about the undergoing treatment do not have a major influence on patient satisfaction. Conclusion: The analysis identified key determinants that should be altered first in order to improve global patient satisfaction. The results also indicate that some aspects of the hospital stay are not seen as relevant by patients and therefore are unrelated to satisfaction ratings. The findings suggest that variables measuring patients' perceptions of care are more important determinants of global patient satisfaction in comparison to demographics and visit characteristics. Results of the present study have implications for health providers aiming at improving the service quality and quality of care. © The Author 2011.
