Abstract
Product development becomes more complex when co-development involves multiple parties crossing boundaries of functions, companies, countries and even competitors. An interdisciplinary framework is needed to understand the challenges of structuring collaborative work within global product teams – especially in the research arenas of strategic partnerships, product development teams, collaboration, distributed work, organizational learning and new metaphors. The multi-party partnership of the Joint Strike Fighter Program at Lockheed Martin, the largest aerospace program in history, provides an illustration of the complex information-sharing and problem-solving challenges in aligning a large, distributed, global integrated product team in an environment where even connectivity is a challenge. It sets the stage for the innovative management approaches needed to build collaborative climates as well as research directions for the future.

Abstract
This article is based upon a paper presented by Major Oliver Stewart to a meeting of The Historical Group of the Royal Aeronautical Society on March 19, 1962, just a few days after the last issue of Major Stewart's own monthly aeronautical journal ‘Aeronautics’ was published. Although some fifteen months have now elapsed since the original paper was presented, it has continuing relevance at this time as the British aeronautical press undergoes further changes. To mention but three examples, the journal ‘Airport and Airline Management’ ceased publication with its May I June 1962 issue, the English language edition of the French ‘Aviation and Space Magazine’ ceased publication with its April 1963 issue, and ‘Aircraft Production’ became a general production engineering journal as from the April 1963 issue. There can be few people better qualified to describe the changing scene of aeronautical journalism, for apart from his experience as a ferry pilot and single‐seat fighter pilot during the First World War and subsequently as an experimental and test pilot at Orfordness and Marilesham Heath, Major Stewart has been aeronautical correspondent of ‘The Morning Post’ (1926–37), ‘The Times’ (1939), ‘The Evening Standard’ (1940) and ‘The Manchester Guardian’ (1941–58). In addition, he was, of course, Editor of ‘Aeronautics’ from the time of its birth in 1939 until its demise last year.

Abstract
Purpose
This scoping review article aimed to systematically search the literature on the use, purpose and barriers of information and communication technology (ICT) for culturally and linguistically diverse (CALD) older adults in the host country. The review also conducted a search for literature on programs that aim to develop digital literacy skills for CALD older adults.
Design/methodology/approach
A scoping review approach was utilized to identify and search the available literature, and to map the key concepts. A total of 23 relevant articles were included following a systematic search across seven databases.
Findings
The review suggests that CALD older adults use ICT for various purposes, including social interaction, health management, information gathering, immigration, everyday routines and leisure. The barriers faced by these older adults in using ICT encompass fear and limited knowledge, language issues, lack of interest, limited access to technology and health concerns. The existing training programs focus on enhancing self-efficacy and confidence and promoting attitudinal changes toward ICT.
Originality/value
Despite the presence of empirical studies, few scoping or systematic reviews have focused on CALD older adults and technology. Research developments related to the technology use of CALD older adults and associated training programs have been fragmented and sporadic, resulting in gaps in the evidence base. This review fills such a gap to better understand the research status connected to CALD older people’s technology adoption and use.

Abstract
This paper makes a comparison between the electrical properties of cement grout with and without monofilament polypropylene fibre additions. The findings show a small, but significant difference between the electrolytic transport properties of cement grout with monofilament polypropylene fibre additions when compared to grout without fibre additions. The grout with fibre additions suggests a reduced probability of water and ion transmission, due to higher measured resistivity, which will result in enhanced durability and lower life cycle costs. Durability of reinforced concrete structures, is known to be closely linked to the water permeability of the concrete matrix. This potential trend for enhanced durability can be added to the other benefits of using monofilament polypropylene fibre in concrete, such as low absorption, freeze/thaw resistance, fire resistance and micro reinforcement.

Abstract
Purpose
The purpose of this paper is to establish whether the inclusion of physical activity (PA) in a community programme setting is more beneficial than the benefit obtained from social participation for older adults.
Design/methodology/approach
A cross-sectional study conducted with a sample of 105 adults age 65+ and older that take part in community activities organised by the Bristol based charity LinkAge. Participants took part in either solely social groups or social groups with a PA component. A self-report questionnaire was composed of measures assessing functional health and well-being, health-related quality of life, functional ability, outcome expectation for exercise, and social support.
Findings
A significantly different and higher score on physical health measures was reported by the physically active group for role physical, physical function, bodily pain, and the physical capacity score. No significant difference was found for health measures that include a mental component. The physically active group reported higher outcome expectations for exercise.
Research limitations/implications
Social activity in community programmes may provide a method to maintain a healthy mental state in older adults, but participation in PA in the same environment is associated with better scores for physical health measures.
Originality/value
Providing greater support for older people to engage in physical and social activities may enable them to maintain a higher quality of life.

Abstract
Purpose
Multi-well hydrofracturing is an important technology to create new fractures and expand existing fractures to increase reservoir permeability. The propagation morphology of the fracture network is affected by the disturbance between the fractures initiation sequences and spacings between adjacent wells. However, it remains unclear how well spacing and initiation sequences lead to fracture propagation, deflection and connection.
Design/methodology/approach
In this study, the thermal-hydro-mechanical coupling effect in the hydrofracturing process was considered, to establish a finite element-discrete element model of multistage hydrofracturing in a horizontal well. Using typical cases, the unstable propagation of hydraulic fractures in multiple horizontal wells was investigated under varying well spacing and initiation sequences. Combined with the shear stress shadow caused by in situ stress disturbed by fracture tip propagation, the quantitative indexes of fracture propagation such as length, volume, displacement vector, deflection and unstable propagation behavior of the hydrofracturing fracture network were analyzed.
Findings
The results show that the shear stress disturbance caused by multiple hydraulic fractures is a significant factor in multi-well hydrofracturing. Reducing the spacing between multiple wells increases the stress shadow area and aggravates the mutual disturbance and deflection between the fractures. The quantitative analysis results show that a decrease of well spacing reduces the total length of hydraulic fractures but increases the total volume of the fracture; compared with sequential and simultaneous fracturing, alternate fracturing can effectively reduce stress shadow area, alleviate fracture disturbance and generate larger fracture propagation length and volume.
Originality/value
The numerical models and results of the unstable propagation and stress evolution of the hydraulic fracture network under thermal-hydro-mechanical coupling obtained in this study can provide useful guidance for the evaluation and design of rock mass fracture networks in deep unconventional oil and gas reservoirs.
