Many quality aspects of software systems are addressed in the existing literature on software architecture patterns. But the aspect of system administration seems to be a bit overlooked, even though it is an important aspect too. In this work we present three software architecture patterns that, when applied by software architects, support the work of system administrators: PROVIDE AN ADMINISTRATION API, SINGLE FILE LOCATION, and CENTRALIZED SYSTEM LOGGING. PROVIDE AN ADMINISTRATION API should solve problems encountered when trying to automate administration tasks. The SINGLE FILE LOCATION pattern should help system administrators to find the files of an application in one (hierarchical) place. CENTRALIZED SYSTEM LOGGING is useful to prevent coming up with several logging formats and locations. Abstract provided by the authors.

With artificial intelligence (AI) systems entering our working and leisure environments with increasing adaptation and learning capabilities, new opportunities arise for developing hybrid (human-AI) intelligence (HI) systems, comprising new ways of collaboration. However, there is not yet a structured way of specifying design solutions of collaboration for hybrid intelligence (HI) systems and there is a lack of best practices shared across application domains. We address this gap by investigating the generalization of specific design solutions into design patterns that can be shared and applied in different contexts. We present a human-centered bottom-up approach for the specification of design solutions and their abstraction into team design patterns. We apply the proposed approach for 4 concrete HI use cases and show the successful extraction of team design patterns that are generalizable, providing re-usable design components across various domains. This work advances previous research on team design patterns and designing applications of HI systems.

Eating healthier at work can substantially promote health for office workers. However, little has been investigated on designing pervasive health interventions specialized in improving workday eating patterns. This paper presents a design study of an mHealth app called EAT@WORK, which was designed to support office workers in the Netherlands in developing healthy eating behaviors in work routines. Based on semi-structured interviews with 12 office workers from a variety of occupations, we synthesized four key features for EAT@WORK, including supporting easy access to relevant knowledge, assisting goal setting, integrating with health programs, and facilitating peer supports. The user acceptance of EAT@WORK was examined through a within-subject study with 14 office workers, followed by a qualitative study on the applicability of app features to different working contexts. Quantitative results showed that EAT@WORK was experienced more useful than a benchmark app (p < 0.01) and EAT@WORK was also perceived easier to use than the benchmark app (p < 0.01). The qualitative analysis suggested that the goal assistant feature could be valuable for different working contexts, while the integrated health program was considered more suitable for office work than telework. The social and knowledge support were expected to be on-demand features that should loosely be bonded with the working contexts. Based on these findings, we discuss design implications for the future development of such mHealth technologies to promote healthy eating routines among office workers.

Purpose – In many organizations, a major part of the daily activities is perceived as concentrated work (53% in this study). Hence, a lack of privacy at the workplace may be considered as a serious environmental stressor. Activity-based work environments usually provide non-assigned private rooms, to be used on an as-need basis. Is this an effective stress management solution?Design/Methodology – Repeated measurements were collected, using a mobile application. Respondents provided data about their activities, the workplaces they used, and the degree of job strain they experienced. They also filled out a questionnaire regarding psychological and job characteristics.Results – A total of 3480 measurements was provided by 114 respondents, working at a Dutch public service organisation. The availability of private rooms did not seem to provide an effective stress management solution. Only 17% of the concentrated work was indeed performed in these rooms. When other types of workplaces were used, this caused (strong) dissatisfaction in 40% of the occasions. This dissatisfaction correlated with individual differences regarding need for privacy (p = .026).Limitations – Because only one specific organization and work environment is studied, further research is needed to test the generalizability of our findings.Research/Practical Implications – When performing concentrated work, people often choose not to use a private room, despite their dissatisfaction. Further research should focus on explaining and possibly influencing this behaviour.Originality/Value – Repeatedly measuring activity type together with workplace type and workplace satisfaction, provides a solid basis to analyse behavioural patterns and environmental stressors within activity-based work environments.

Movement behaviors, that is, both physical activity and sedentary behavior, are independently associated with health risks. Although both behaviors have been investigated separately in people after stroke, little is known about the combined movement behavior patterns, differences in these patterns between individuals, or the factors associated with these patterns. Therefore, the objectives of this study are (1) to identify movement behavior patterns in people with first-ever stroke discharged to the home setting and (2) to explore factors associated with the identified patterns.

Social innovation is the renewal of labour organisation that leads to improved performance by the organisation. The innovations that are promoted under the heading of social innovation often require substantive behavioural change on the part of employees and managers. However, in many organisations there are hidden, often unconscious forces at work that make it difficult to implement these new ways of working. In this paper Maslow‟s hierarchy of needs and transactional analysis theory are used to identify possible barriers for the implementation of social innovation. A case study is presented to show how potential barriers can be identified.

Purpose: This conceptual paper explores the problems associated with trying to address culture as one of the key aspects in effective workplace strategies. Design/methodology/approach: This paper critically addresses the relationship between workplace strategies and the behavioural components of locality. It reviews the role that the concept of culture has, so far, played in trying to predict these behavioural consequences as part of (literature discussing) efforts to design appropriate workplace strategies. Findings: The discussion reveals the need to further address this relation through dedicated research. What is more, it is argued that there is a clear need to focus explicitly on work patterns, and how these can be accounted for in workplace strategies, instead of continuing to focus on the concept of culture as a predictor for successfulness. It is argued that the latter does not allow for practical application, whereas the former could help us to better understand and predict the effectiveness of specific workplace strategies in specific (local) circumstances. Practical implications: The outcome of the discussion suggests that organisations consisting of multiple locations could benefit from explicitly accounting for (local) work patterns in setting up workplace strategies for the organisation as a whole. Originality/value: This paper reveals a relevant research gap in current literature on workplace strategies and suggests a shift in focus from culture to work patterns as one of the key aspects to address.

Social work is a profession that is very much part of and contributes to an ever changing and evolving society. It is therefore essential that social work is able to respond to the diverse and dynamic demands that it may encounter in that society and in the future. The critique of social work is, however, present and growing. The profession can no longer deny or ignore the need to legitimize its value and effectiveness. In this article, a research project – entitled Procivi – aimed at developing a method of legitimizing social work is presented. The method developed in Procivi proposes a way of legitimizing social work through the development of reflective professionals. The method teaches professionals to take a research frame of mind towards their own practice and helps them develop a vocabulary to describe their work to different audiences. The paper discusses whether and how this method forms a viable way of legitimizing social work and as such could be an alternative for the growing demand for social work based on scientific evidence (evidencebased practice, EBP).

The central question in this study is how, for whom, and under which conditions professional youth work contributes to the personal development of socially vulnerable youngsters, the reinforcement of their social network, the enhancement of their social participation, and the timely finding of appropriate specialized care services in relation to contextual factors such as life events and the influence of significant others. This research used a multiple case study with a comparative design. During a 12-month period, youth workers (N = 20) participated in group intervision meetings and kept diaries reporting on their actions and the development of the youngsters (N = 23). An analysis of this data revealed four patterns of development of socially vulnerable youngsters in youth work settings. Each pattern consisted of a specific form of multi-methodic action that resulted in a specific outcome. The study also revealed how these processes of development are influenced by important life events and significant others. The findings suggest that youth work contributes to personal development and social participation and thereby may lessen the need for formal social care services.
