Abstract
Purpose
This paper aims to describe an effort to provide for a robust and secure software development paradigm intended to support DevSecOps in a naval aviation enterprise (NAE) software support activity (SSA), with said paradigm supporting strong traceability and provability concerning the SSA’s output product, known as an operational flight program (OFP). Through a secure development environment (SDE), each critical software development function performed on said OFP during its development has a corresponding record represented on a blockchain.
Design/methodology/approach
An SDE is implemented as a virtual machine or container incorporating software development tools that are modified to support blockchain transactions. Each critical software development function, e.g. editing, compiling, linking, generates a blockchain transaction message with associated information embedded in the output of a said function that, together, can be used to prove integrity and support traceability. An attestation process is used to provide proof that the toolchain containing SDE is not subject to unauthorized modification at the time said critical function is performed.
Findings
Blockchain methods are shown to be a viable approach for supporting exhaustive traceability and strong provability of development system integrity for mission-critical software produced by an NAE SSA for NAE embedded systems software.
Practical implications
A blockchain-based authentication approach that could be implemented at the OFP point-of-load would provide for fine-grain authentication of all OFP software components, with each component or module having its own proof-of-integrity (including the integrity of the used development tools) over its entire development history.
Originality/value
Many SSAs have established control procedures for development such as check-out/check-in. This does not prove the SSA output software is secure. For one thing, a build system does not necessarily enforce procedures in a way that is determinable from the output. Furthermore, the SSA toolchain itself could be attacked. The approach described in this paper enforces security policy and embeds information into the output of every development function that can be cross-referenced to blockchain transaction records for provability and traceability that only trusted tools, free from unauthorized modifications, are used in software development. A key original concept of this approach is that it treats assigned developer time as a transferable digital currency.

Abstract
Purpose
Many organizations struggle to achieve their desired levels of business process flexibility and support. However, these two capabilities conflict with each other and different tradeoffs have to be made. In this paper, the authors analyze different process conceptualizations and discuss their implications. The authors argue that the conceptualizations people adopt to think (conceptualize) about business processes affect the way they model them, which in turn result in different flexibility-support tradeoffs.
Design/methodology/approach
A set of properties is proposed to compare process conceptualizations: dominant concept, contract, and existential and representational properties. Using these properties, several process conceptualizations are analyzed and integrated in a comparison chart, which highlights different flexibility-support tradeoffs. The storytelling method is adopted to support the analytic process.
Findings
The authors show how different process conceptualizations result in different flexibility-support tradeoffs. The authors suggest that we need to intervene on a set of properties of process conceptualizations to achieve different flexibility-support tradeoffs.
Research limitations/implications
This research contributes to understanding the relationships between process conceptualizations, process modeling, and the flexibility-support tradeoff. A comparison chart helps organizations analyze their desired levels of flexibility and support using a set of properties.
Originality/value
The extent of covered viewpoints makes this study unique in the process management field. Such effort provides a contribution towards a more multidisciplinary discussion of process models, which integrates different process conceptualizations.

Abstract
In times of converging and diversifying audiovisual (AV) industries, digitising health sector and the increasing phenomenon of cross-sectoral innovation, the question arises about the state of affairs between the health and AV sectors. The chapter aims to explore what the main modes of cross-sectoral cooperation between the health and AV sectors are and what supports and hinders the emergence of a related cross-innovation system. The chapter introduces two case studies carried out in Estonia and the wider Aarhus region (Midtjylland) in Denmark. At each site representatives of the main stakeholders of both sectors were interviewed – policy makers, entrepreneurs, educators and professionals. The results demonstrate the crucial role of path-dependencies – in terms of both hindering and enabling cross-sectoral dialogues – and also the importance of effective coordination in supporting cross-innovation.

Abstract
Purpose
The purpose of this paper is to present a case study of work performed at the London School of Hygiene and Tropical Medicine to set-up a Research Data Management Service and tailor it to the needs of health researchers.
Design/methodology/approach
The paper describes the motivations for establishing the RDM Service and outlines the three objectives that were set to improve data management practice within the institution. Each of the objectives are explored in turn, stating how they were addressed.
Findings
A university with limited resources can operate a RDM Service that pro-actively supports researchers wishing to manage research data by monitoring evolving support needs, identifying common trends and developing resources that will reduce the time investment needed. The institution-wide survey identified a need for guidance on developing data documentation and archiving research data following project completion. Analysis of ongoing support requests identifies a need for guidance on data management plans and complying with journal sharing requirements.
Research limitations/implications
The paper provides a case study of a single institution. The results may not be generally applicable to universities that support other disciplines.
Practical implications
The case study may be helpful in helping other universities to establish an RDM Service using limited resources.
Originality/value
The paper outlines how the evolving data management needs of public health researchers can be identified and a strategy that can be adopted by an RDM Service to efficiently address these requirements.

Abstract
Purpose
Socio-cultural impacts of tourism have been widely researched within a social exchange theoretical framework, yet it seems that this theory could be neglecting those more emotional elements, which at the same time could be considered key to understand how tourism affects the society. Therefore, the purpose of this paper is to look at the social exchange theory (SET) from a different perspective and focus on those less rational influencing factors that could be shaping residents’ attitudes towards tourism.
Design/methodology/approach
Based on six main constructs, a quantitative survey-based research is developed in the small city of Girona with the purpose to broaden the versality of the theory, with the support of in-depth exploratory interviews. Thus, an exhaustive study of the influences that attachment to communities, involvement in the tourism industry and personal benefits derived from tourism could have on residents’ perceptions is developed.
Findings
This paper suggests that those smaller tourism destinations might mirror themselves in those close big tourism destinations and thus residents’ opinions and attitudes seem to be influenced by the situations lived in these larger tourism destinations. Moreover, this paper stresses on the importance of interactions and relationships between tourists and residents to boost personal benefits from tourism. Finally, results show how those attached citizens tend to support tourism development, which could be explained by the proudness they feel when others value what for them is home.
Originality/value
This paper contributes to the current understanding of attitudes towards tourism within the SET framework, especially relating to covering those more emotional elements of social interactions. Moreover, there seems to be a gap in current research relating to small urban destinations that is aimed to be covered in this research.

Abstract
Purpose
This study aims to test the role that organizational sociopsychological variables may play in influencing job stress and work engagement in an organizational identity change scenario.
Design/methodology/approach
On a sample of 118 employees of an Italian company in the personnel training services sector, multivariate statistical analysis tests a pattern where organizational variables such as work support (by supervisors and coworkers, independent variables) – moderated by corporate identification (moderating variable) – and mediated by organizational trust (mediating variable) – boosts employee work engagement and lowers psychosocial risks (dependent variables).
Findings
The mediating effect of “organizational trust” is significant in the relationships of “supervisor social support” and “coworker social support” with the “absence of psychosocial risks.” Moreover, an increase in supervisor social support can lead to a statistically significant increase in work engagement. This occurs only for employees with low or medium identification and not in highly identified individuals.
Originality/value
The findings from the analysis on moderation are of primary importance because they show us a new perspective that can play the role of a guiding and practical principle on how to act on an organization’s human resources, specifically targeting those with lower or medium corporate identification.

Abstract
Purpose
The European H2020 Families_Share project aims at offering a grass-root approach and a co-designed platform supporting families for sharing time and tasks related to childcare, parenting, after-school and leisure activities and other household tasks. To achieve this objective, the Families_Share project has been built on current practices which are already leveraging on mutual help and support among families, such as Time Banks, Social Streets and self-organizing networks of parents active at the neighbourhood level and seek to harness the potential of ICT networks and mobile technologies to increase the effectiveness of participatory innovation. The aim of this paper is to present and discuss the Families_Share methodology and platform, as well as the results obtained by several partecipating communities in different European countries.
Design/methodology/approach
This paper discusses how the Families Share approach (CAPS project, Horizon 2020) is bringing the sharing economy to childcare. Families Share developed a co-caring approach and a co-designed digital welfare platform to support parents with sharing time and tasks related to childcare, after-school and leisure activities. Families Share conducted two iterative pilot experiments and related socio-economic evaluations in six European cities. More than 3,000 citizens were engaged in the co-design process through their local community organizations and more than 1,700 parents and children actively experimented with the approach by organizing collaborative childcare activities. The authors discuss the challenges and solutions of co-designing a socio-technical approach aimed at facilitating socially innovative childcare models, and how the Families Share approach, based on technology-supported co-production of childcare, may provide a new sustainable welfare model for municipalities and companies with respect to life––work balance.
Findings
The authors discuss the challenges and solutions of co-designing a technological tool aimed at facilitating socially innovative childcare models, and how the Families Share approach may provide a new sustainable welfare model for municipalities and companies with respect to work–life balance.
Originality/value
As a main difference with state-of-the-art proposals, Families_Share is aimed to provide support to networks of parents in the organization of self-managed activities, this way being orthogonal with respect either to social-network functionalities or to supply and demand services. Furthermore, Families_Share has been based on a participative approach for both the ICT platform and the overall structure.

Abstract
Purpose
Recent research acknowledges entrepreneurial passion’s outcomes, but far less is known about how entrepreneurial passion comes about. In this study, the authors are interested in the emergence of entrepreneurial passion, and how competences and social network are associated with entrepreneurial passion. The paper aims to discuss these issues.
Design/methodology/approach
The authors investigate whether entrepreneurial passion emerges out of socialisation, entrepreneurial experience or various combinations thereof. The authors tested the hypotheses on a data set of entrepreneurs who started their businesses with government financial support (n=1150).
Findings
The findings show that within a social environment, perceived emotional support is positively associated with entrepreneurial passion. Moreover, entrepreneurs’ task-related competence moderates this relationship positively. By investigating the emergence of entrepreneurial passion, the authors contribute to prior passion literature, which has mainly focused on its consequences.
Originality/value
The findings demonstrate both how entrepreneurial passion is associated with and how perceived emotional support can stem from unexpected sources, such as from a government-based start-up grant. For entrepreneurs, an increased awareness of passion’s emergence could better encourage them in their entrepreneurial endeavours. To people who are engaged in promoting entrepreneurship, our findings emphasise the symbolic and emotional aspects of instruments intended to support entrepreneurship.

Abstract
Purpose
The World Health Organization (WHO) recommends exclusive breastfeeding for the first six months of a child's life. However, while the national coverage was 61.33%, the coverage in Sukoharjo was 39.33%. Effective intervention is needed to promote the importance of exclusive breastfeeding, and this requires knowledge of the barriers and support structures in place. This study analyzed the supports and barriers of exclusive breastfeeding in Sukoharjo, Central Java, Indonesia.
Design/methodology/approach
This qualitative study used in-depth interviews conducted from December 2017 to March 2018. The population consisted of 33 informants (29 mothers with babies over six months of age, a pregnant mother, two midwives working in the community health center and a staff member in the district health department).
Findings
There were barriers to and support for exclusive breastfeeding in Sukoharjo, Central Java province, Indonesia. The district already has support systems in place, while the barriers emerge from society, the baby's condition, environmental and other sources. The government has tried to overcome the barriers.
Research limitations/implications
The limitation of this study was that the triangulation method was not utilized. However, the use of various informants strengthened the findings.
Practical implications
The district government, especially the health department, needs to establish a program to evaluate existing exclusive breastfeeding support programs thoroughly. Smarter and more comprehensive interventions may be needed, for example, by integrating various supports into one activity. For researchers, the findings of this study imply that they can conduct experimental community research using the framework of the two aforementioned theories of behavior change. For example, investigation of combining the support of trained peers with the presence of family members such as the grandmothers of the babies. If both types of support are conducted concurrently, it may strengthen support and reduce barriers from either inside or outside the home.
