The traditional artificial mode of engineering change implementing in aero-engine assembly field often results in difficulties of the process control. To solve this problem, this paper firstly puts forward an aero-engine assembly field configuration relationship model (AACRM) based on the configuration data structure and correlation coordination relationship between configuration items, then analyzes the structure of engineering change document and its implementation process in assembly field. Lastly, assembly field engineering change implementing process model (AEIPM) is established based on Petri nets modeling method, which constructs the implementing and confirming process of engineering change from a product level to a step level and then from a step level to a product level.

The mosque has been a focal point of Islam since its inception, serving as a place of worship, a centre of education, economic pursuits, communal services, and spirituality. However, due to a variety of causes, the scope of mosque functions has been constrained as the world has developed rapidly. In summary, congregational capacity and facilities relating to hygiene, safety, and space utilisation are among the problems being closely examined in Malaysia. Based on the problems, the subject of mosque management's competencies that need to be improved in order to become more professional arises. Reviews of literature suggested that facilities management (FM) approach has the potential to be incorporated in the management of mosque. The purpose of this study is to examine the implementation of FM process in mosque in supporting the achievement of mosque’s functions. A quantitative approach was adopted in this study. The implementation of FM process from 12 state mosques in Peninsular Malaysia were investigated using questionnaire survey which distributed among the mosque management that manage mosque facilities. Descriptive statistics were used to analyse the questionnaire survey data with Statistical Package for the Social Sciences (SPSS) software. Results from the questionnaire survey revealed that, 50 per cent of the mosque has implemented most of the FM process model elements whereas other mosque still need further improvement to ensure the standards of FM process model is achieved. The results indicated that there is potential for improvement in mosque that possesses low position in implementing elements of FM process model that includes FM formulation strategy, requirement analysis of services, FM solutions development, FM solutions implementation and monitoring service provision. The finding could assist the top management level of the mosque in strategising the implementation action plan of mosque facilities management.

Abstract Background:Choosing Wisely (CW) is an international movement comprised of national campaigns in more than 20 countries to reduce low-value care (LVC). Hospitals and healthcare providers are examining existing practices and putting interventions in place to reduce practices that offer little to no benefit to patients or may cause them harm. De-implementation, the reduction or removal of a healthcare practice is an emerging field of research. Little is known about the factors which (i) sustain LVC; and (ii) the magnitude of the problem of LVC. In addition, little is known about the processes of de-implementation, and if and how these processes differ from implementation endeavours. The objective of this study was to explicate the myriad factors which impact the processes and outcomes of de-implementation initiatives that are designed to address national Choosing Wisely campaign recommendations.Methods:Semi-structured interviews were conducted with individuals implementing Choosing Wisely Canada recommendations in healthcare settings in four provinces. The interview guide was developed using concepts from the literature and the Implementation Process Model (IPM) as a framework. All interviews were conducted virtually, recorded, and transcribed verbatim. Data were analysed using thematic analysis.Results:Seventeen Choosing Wisely team members were interviewed. Participants identified numerous provider factors, most notably habit, which sustain LVC. Contrary to reporting in recent studies, the majority of LVC in the sample was not ‘patient facing’; therefore, patients were not a significant driver for the LVC, nor a barrier to reducing it. Participants detailed aspects of the magnitude of the problems of LVC, specifically the impact of harm and resources. Unique factors influencing the processes of de-implementation reported were: influence of Choosing Wisely campaigns, availability of data, lack of targets and hard-coded interventions.Conclusions: This study explicates factors ranging from those which impact the maintenance of LVC to factors that impact the success of de-implementation interventions intended to reduce them. The findings draw attention to the significance of unintentional factors, highlight the importance of understanding the impact of harm and resources to reduce LVC and illuminate the overstated impact of patients in de-implementation literature. These findings illustrate the complexities of de-implementation.

Purpose Organizations learn semi-automatically through experience or consciously through deliberate learning efforts. As there seems to be a “black-box” in the possible linkages between deliberate learning and new practice implementation, this paper aims to develop and test a process model, linking deliberate learning and new practice implementation through complementary competencies of task and environmental flexibility. Design/methodology/approach As part of a field study, health-care improvement program (to transfer the improvement training program for new practice implementation) of 186 HCUs was used for testing our hypothesis. In addition to descriptive statistics, multiple hierarchical regressions and bootstrapping were used to test the study hypotheses. Findings Findings suggest that deliberate learning is positively and significantly related with new practice implementation, and dynamic capabilities in the form of task and environmental flexibility mediates this relationship. Research limitations/implications The present study makes theoretical and practical contributions by linking literature from new practice, organizational learning and dynamic capabilities; and by delving into the deliberate learning activities undertaken by health-care units. Originality/value Organizational learning in health care has almost become inevitable today due to the ever-changing dynamics of the industry. Barring handful of studies, the current state of literature is almost entirely tilted towards experience-based learning and deliberate learning is not well studied. To address this gap, the study aims to develop and test a process model linking development of dynamic capabilities with deliberate learning and new practice implementation. Further, findings of this study will help organizations and managers to understand and thereby effectively manage new practice implementation process through the use of deliberate activities.

For the application of Additive Manufacturing (AM), a wide range of use cases are applied in industrial practice. The technological potentials of AM enable specific business models, which characterise how AM utilisation adds value to a company’s business. For the implementation of AM, a paradigm shift is required on an operational and strategic level, making it necessary to adjust processes and structures. Herein, the interdisciplinary character of the technology needs to be taken into account. In this paper, a typology of AM business models is derived from specific technology potentials, providing orientation in the field of AM use cases. Furthermore, a top down approach is pursued in order to develop an implementation process model, which assists companies when considering AM adoption. It enables companies to identify suitable AM business models and points out fields of actions necessary for implementation. Since the implementation depends on the AM business model at scope, also guidelines that provide measures on a more detailed level are presented.

In most cases, the traditional Web-based learning management systems (e.g. Moodle, Blackboard) have been designed without any built-in support for a preferred pedagogical model or approach. The proponents of such systems have claimed that this kind of inherent "pedagogical neutrality" is a desirable characteristic for a LMS, as it allows teachers to implement various pedagogical approaches. This study is based on an opposite approach, arguing for designing next-generation online learning platforms - so called digital learning ecosystems - with built-in affordances, which promote and enforce desirable pedagogical beliefs, strategies and learning activity patterns while suppressing others. We propose a conceptual and process model for pedagogy-driven design of online learning environments and illustrate it with a case study on development and implementation process of a digital learning ecosystem based on Dippler platform. We also describe the pedagogical foundation of Dippler that was guided by a combination of four contemporary pedagogical approaches: self-directed learning, competence-based learning, collaborative knowledge building and task-centered instructional design.


Assimilation of a standard ERP system to an organization is difficult. User involvement seems to be the crux of the matter. However, even the best intentions for user involvement may come to nothing. A case study of a five-year ERP implementation process reveals that a main reason may be that the perception of usefulness of the system in any given phase of the implementation is heavily dependent on preceding events—the process. A process model analysis identifies eight episodes and nine encounters in the case showing that the user’s attitude towards the ERP system changes between acceptance, equivocation, resistance and rejection depending on three things: (1) the dynamic between user and consultants, (2) the dynamic between different user groups, and (3) the understanding of technical, organizational and socio-technical options. When relating the empirical findings to existing theory on user participation, it is argued that the changes could be explained as a slide from influential user participation toward pseudo participation and back to influential participation, and that user participation in the context of ERP implementations raises new issues regarding user participation. Thus further research regarding new approaches and/or new techniques and tools for user participation in the context of ERP implementations is needed.

Multiple interdependent issues negotiations have been widely studied since most real-world negotiation involves multiple interdependent issues. Our work focuses on negotiation with multiple interdependent issues in which agent utility functions are nonlinear. In the field of multiple issue negotiations, there are no established common testbeds for evaluating protocols. In this paper, we propose a common testbed creating tool based on XML that mainly covers the utility functions based on cube-constraints and cone-constraints. First, we propose a testbed generating tool that inputs configuration data and outputs XML formatted files that represent agent utility spaces. The current tool can produce four types of utility spaces: Random, A Single Hill, Two-Hills, and SeveralHills. These types are observed in real negotiation settings. Also we define the agent’s utility space information based on XML formats. By defining the testbed data as XMLs, users can easily read the files and change the data structure.
