From the article: Abstract Business rules (BR’s) play a critical role in an organization’s daily activities. With the increased use of BR (solutions) and ever increasing change frequency of BR’s the interest in modifiability guidelines that address the manageability of BR’s has increased as well. A method of approach to improve manageability and modifiability is to utilize architectures to structure BR’s. In current literature three different methods to structure business rules can be identified: 1) the rule family-oriented approach, 2) the fact-oriented approach and, 3) the decision-oriented approach. Scientific research comparing the ability to modify business rules in each of the three architectural candidates is limited. The goal of this research is to evaluate which architectural candidate and underlying architectural structures allow for the best modifiability. We sought to do so by applying design science research for the creation of the architectural candidates and by conducting semi-structured interviews to identify the case-specific productivity scores. By applying an Architecture-Level Modifiability Analysis using eight years of historical data from the British National Health Service each architectural candidate is evaluated with regards to its modifiability. Results of the analysis reveal that the rule family-oriented architecture scores best on modifiability, followed by the fact-oriented architecture, and lastly the decision-oriented architecture. The results of this study provide a foundation for further research on the application and evaluation of business rule architectures.

Background Identify and establish consensus regarding potential prognostic factors for the development of chronic pain after a first episode of idiopathic, non-traumatic neck pain. Design This study used two consensus group methods: a modified Nominal Group (m-NGT) and a Delphi Technique. Methods The goal of the m-NGT was to obtain and categorize a list of potential modifiable prognostic factors. These factors were presented to a multidisciplinary panel in a two-round Delphi survey, which was conducted between November 2018 and January 2020. The participants were asked whether factors identified are of prognostic value, whether these factors are modifiable, and how to measure these factors in clinical practice. Consensus was a priori defined as 70% agreement among participants. Results Eighty-four factors were identified and grouped into seven categories during the expert meeting using the modified NGT. A workgroup reduced the list to 47 factors and grouped them into 12 categories. Of these factors, 26 were found to be potentially prognostic for chronification of neck pain (> 70% agreement). Twenty-one out of these 26 factors were found to be potentially modifiable by physiotherapists based on a two-round Delphi survey. Conclusion Based on an expert meeting (m-NGT) and a two-round Delphi survey, our study documents consensus (> 70%) on 26 prognostic factors. Twenty-one out of these 26 factors were found to be modifiable, and most factors were psychological in nature.
AbstractBackground: Ecological models are currently the most used approaches to classify and conceptualise determinantsof sedentary behaviour, but these approaches are limited in their ability to capture the complexity of and interplaybetween determinants. The aim of the project described here was to develop a transdisciplinary dynamic framework,grounded in a system-based approach, for research on determinants of sedentary behaviour across the life span andintervention and policy planning and evaluation.Methods: A comprehensive concept mapping approach was used to develop the Systems Of Sedentary behaviours(SOS) framework, involving four main phases: (1) preparation, (2) generation of statements, (3) structuring (sorting andranking), and (4) analysis and interpretation. The first two phases were undertaken between December 2013 andFebruary 2015 by the DEDIPAC KH team (DEterminants of DIet and Physical Activity Knowledge Hub). The lasttwo phases were completed during a two-day consensus meeting in June 2015.
