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.

In this paper, we present a set of Eclipse plug-ins which adapts the idea of regression testing for the area of visual modelling in software engineering: Expected properties of models in languages such as UML, BPMN, etc. are stored together with the model (comparable with test cases added to software). With each change of the model, these properties can be checked. The solution should work with any visual modelling language included into Eclipse - both for standardised as for domain-specific languages. The advantage of our approach over current existing solutions is that the process of model checking is completely hidden to the modeller. In particular, it is not necessary for the modeller to learn a formalism for specifying expected properties. Copyright 2017 for this paper by its authors.

We describe the experiences from a project in the medical domain where processes were modeled in modeling sessions in close co-operation with physicians. In this project, we experienced diffculties in modeling exibilities within processes. Flexible and knowledge-intensive processes do not follow a gixed sequence of steps, but rely on knowledge and experience of the medical staff. During the process execution process, the actors can decide for additional steps, change the execution order or skip a task. In standard business process modeling languages, it is not clear how to model such exible situations. We observed, however, that many exible situations can be described by recurring patterns. We argue that those patterns can be used as building blocks for communication among the stakeholders. The advantage is that those building blocks are close to the vocabulary that is used when domain experts describe a process. The patterns can support the process modeler to recognize exible situations in processes. In addition, a pattern catalog can recommend a way to model such situations in a suitable way in a standardized modeling language.

The planning and design process for training circuits for the automobile industry has not used any standard methodology anywhere in the past. The new 3D alignment for a training course consists of measured individual elements from existing tracks combined with newly marked sequences of elements (generalized spline function). To drive the training circuit at maximum speed along sections, the driver uses the course's full width and seeks a racing line that most closely matches the ideal theoretical. Zwickau University has developed a new interactive design methodology by using driving simulation to prevent accidents on training circuits as far as possible. © 2017 The Authors.

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.

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.

The paper presents a conceptual model and an engineering solution to agile building of supply chains in industrial networks through their integrated product-process driven modularising and flexible structuring. This study first presents the competence-cell-based approach that integrates the product and process modularisation-driven postponement and flexible supply chain structuring. Subsequently, the elaborated engineering solution to an integrated product-process driven modularising and structuring of supply chains is presented. With the results of this study, customer-oriented product design and customer-oriented networking of supply processes have been brought to a joint consideration.

Regional and national policy makers have invested heavily in the cluster concept as a means of generating value for regions, particularly through the opportunities it may present for small regional enterprises as vehicles for growth and job creation. Economic theorists such as Porter, have shaped many of policies being adopted, from a macro-economic perspective, yet the process by which actors within the group are helped (or hindered) in aligning knowledge, expertise and interests is less well understood. The implementation and development of clusters is subject to a range of local socio-technical and socio-political dynamics, which also need to be taken account of if the anticipated benefits such as wealth creation and competitiveness are to be realised. The paper uses the outcomes of research in several regional clusters to highlight recurring issues associated with the alignment of distributed knowledge and stakeholder interests, and in particular, the interests of small and medium-sized enterprises (SMEs). The paper suggests that such barriers impact on the ability of clusters to create value for regions, particularly in relation to the opportunities for the creation of employment through local SMEs that are often cited as the basis for such investment. The authors argue for the provision of opportunities to sharing knowledge and expertise within and between clusters, to ensure early identification and collective engagement of stakeholders with issues on the ground, given the evidence that SME are under-represented in policy and strategy development, and that this undermines the competitiveness and the benefits of investment in regional clusters. © 2011 Elsevier B.V.

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.

Similarity measures for business process models have been suggested for different purposes such as measuring compliance between reference and actual models, searching for related models in a repository, or locating services that adhere to a specification given by a process model. The aim of our article is to provide a comprehensive survey on techniques to define and calculate such similarity measures. As the measures differ in many aspects, it is an interesting question how different measures rank "similarity" within the same set of models. We investigated, how different kinds of changes in a model influence the values of different similarity measures that have been published in academic literature. Furthermore, we identified eight properties that a similarity measure should have from a theoretical point of view and analysed how these properties are fulfilled by the different measures. Our results show that there are remarkable differences among existing measures. We give some recommendations which type of measure is useful for which kind of application. © 2011 Elsevier B.V.
