Abstract
Purpose
Designing technologies for active and healthy ageing (AHA) requires a subtle understanding of end users (primary stakeholders) and healthcare professionals (secondary stakeholders). Often, their perspectives can be heterogeneous and contradictory. Identifying and negotiating them may be a challenge for designers. The purpose of this paper is to present our approach to understanding and negotiating contradictory stakeholder perspectives when designing AHA technologies for older adults.
Design/methodology/approach
The authors conducted an exploratory interview study with 15 community-dwelling older adults and 11 healthcare stakeholders, including doctors, health insurance agencies, policymakers and caregivers. The authors analyzed the interview material and negotiated contradictory perspectives.
Findings
Three major issues among stakeholders emerged: perspectives on AHA; perceived benefits and drawbacks of AHA technologies; and concerns about data privacy, control and trust.
Research limitations/implications
The results show the heterogeneity and contradictions in stakeholder perspectives on AHA technologies and how these perspectives may be negotiated. This could help understand and facilitate long-term use of AHA technologies among older adults.
Originality/value
This study alerts researchers to contradictory perspectives among older people and healthcare stakeholders and the importance of involving them in the design of AHA technologies.

Abstract
Purpose
Invented in late 1890s, asbestos cement sheeting rose to prominence during the post-Second World War period as a building material for low-cost housing by state housing commissions and low-income families (“fibro homes”). The adverse health effects of asbestos fibres in the building industry and home renovation activities are well documented. Fibro homes of the 1950s and 1960s are increasingly coming under the gaze of heritage studies, which brings to the fore the question of how to deal with the asbestos cement sheeting most are clad with.
Design/methodology/approach
This paper provides the first systematic review to assess the literature (126 papers were identified in Google Scholar and scanned for content) on the conservation management of asbestos cement sheeting in heritage properties.
Findings
Overall, engagement with the conservation management of asbestos cement sheeting in heritage properties was low, with only two sources dealing with asbestos cement sheeting in any level of detail. The studies note that if asbestos cement sheeting is in good condition, it should be left alone. Numerous conservation and repair options do exist, in particular the application of (coloured) sealants that extend the life of asbestos cement sheets and asbestos cement roofing.
Originality/value
This paper represents the first systematic review to assess conservation management options for asbestos cement sheeting in heritage properties.

Abstract
Purpose
Birds are implicated in spoiling and decay of buildings, especially through their droppings. Pigeons are considered the main culprits, and several studies have examined the effects and chemistry of accumulations of droppings without evidence to the exact origins of the source of the excreta. The paper aims to discuss these issues.
Design/methodology/approach
This study reviews and summarises the state of knowledge with regard to the impact of bird excreta on buildings. It experimentally assesses the acidity of fresh pigeon excreta with different diets and examines the development of the acidity of the excreta after voiding.
Findings
Feral pigeons in urban settings are known to be fed by a range of foods. Urban food scraps-derived diets produce more acidic excreta than more natural diets such as seeds. This is a first study of its kind to examine the impact of a bird’s diet on the pH and thus the resulting (potential) decay of masonry.
Research limitations/implications
This study showed that from a management’s perspective, pigeons that subsist entirely on human provided foods will be depositing more initially acidic faeces. If faecal accumulation occurs; then, mould and other bacteria quickly alter the chemistry from acidic towards basic, but the damage may already be done.
Originality/value
This paper is the first study of its kind to examine the effects of fresh pigeon droppings of known origin and age once voided from the intestine. This allows the authors to assess the impact during the first few days.

Abstract
Purpose
There is much anecdotal evidence that birds and their droppings are a major problem for the heritage profession. The purpose of this paper is to examine how serious heritage practitioners consider the bird impact to be.
Design/methodology/approach
An online survey was conducted of 59 Australian heritage professionals of between one and >20 year’s experience in the field.
Findings
Bird impacts were not considered of major concern to buildings. The longer experience a practitioner had, the less likely the impacts were considered an issue. Feral pigeons were deemed the most problematic, followed by cockatoos, starlings, swallows, seagulls, mynas, sparrows, cormorants, ibis, ducks and birds of prey. The professionals ranked common deterrent methods. The highest-ranking deterrents were bird netting and bird spikes, but they were only considered moderately effective. The costs of installation and maintenance, as well the ease of installation, were all deemed significantly less important than the physical impact, the aesthetic sympathy and the effectiveness of a deterrent method.
Practical implications
This study indicates that the impact of birds on buildings in Australia may be of less concern than previously thought, and may be driven by other factors (i.e. aesthetics, commercial companies) rather than actual effects.
Originality/value
This is first study of its kind that surveyed the experiences of a wide range of heritage practitioners.

Abstract
This paper details a longitudinal study into the e‐mail habits of first year students at Charles Sturt University. This study is part of ongoing research investigating the factors and barriers that can influence the successfully adoption of technology into the learning environment. The findings from this study illustrate that e‐mail applications are very popular in terms of both useage as well as the high level of confidence that students exhibit. The survey identified two main areas that need to be addressed, namely the disadvantage of rural students in accessing e‐mail and second that male students tend not to be as frequent users of e‐mail compared to their female counterparts.

Abstract
Purpose
The use of generative artificial intelligence (genAi) language models such as ChatGPT to write assignment text is well established. This paper aims to assess to what extent genAi can be used to obtain guidance on how to avoid detection when commissioning and submitting contract-written assignments and how workable the offered solutions are.
Design/methodology/approach
Although ChatGPT is programmed not to provide answers that are unethical or that may cause harm to people, ChatGPT’s can be prompted to answer with inverted moral valence, thereby supplying unethical answers. The authors tasked ChatGPT to generate 30 essays that discussed the benefits of submitting contract-written undergraduate assignments and outline the best ways of avoiding detection. The authors scored the likelihood that ChatGPT’s suggestions would be successful in avoiding detection by markers when submitting contract-written work.
Findings
While the majority of suggested strategies had a low chance of escaping detection, recommendations related to obscuring plagiarism and content blending as well as techniques related to distraction have a higher probability of remaining undetected. The authors conclude that ChatGPT can be used with success as a brainstorming tool to provide cheating advice, but that its success depends on the vigilance of the assignment markers and the cheating student’s ability to distinguish between genuinely viable options and those that appear to be workable but are not.
Originality/value
This paper is a novel application of making ChatGPT answer with inverted moral valence, simulating queries by students who may be intent on escaping detection when committing academic misconduct.

Abstract
An extension of the Scharfetter‐Gummel discretization scheme is presented which is designed for electrothermal semiconductor device equations including avalanche generation terms. The scheme makes explicit use of the exponential character of solutions, and reduces to the standard Scharfetter‐Gummel scheme in the isothermal non‐avalanche case.

Abstract
Purpose
Theories of trust imply that team trust develops and grows over time, yet relatively few researchers have taken on the challenge of studying team trust in longitudinal research designs. The purpose of this chapter is to provide a concise summary of the existing literature on team trust over time, and to offer a conceptual model of team-level trust development over time to aid future research on this topic.
Methodology/approach
We draw from the Input–Mediator–Output–Input (IMOI) framework, as well as previous multilevel models of organizational trust development, and published findings from longitudinal team trust studies.
Findings
Taking a temporal perspective, we consider how team-level mediators and outcomes can both predict and be predicted by team trust trajectories and feedback loops over time, as well as how those relationships with team trust might change based on the existence of other moderating variables including trust violation and repair.
Research implications
Future longitudinal team research may use the model as a starting point for investigating the antecedents, as well as the team processes and dynamic emergent states, that can effectively predict trajectories of team trust across various stages of teamwork.
Practical implications
Based on our review of extant literature, we provide several recommendations for training and organizational intervention including the importance of management’s consideration of team-level trust in providing feedback, enhancing cohesion, and mitigating conflict.
Originality/value
We provide insight into the development of team trust trajectories and offer a framework to help guide future longitudinal team trust research.

Abstract
When a firm implements certain HR practices, different employees attribute different motives and intentions to the firm with regard to those HR practices. Research on HR attributions has made progress toward understanding the relationship between HR practices and employee outcomes from a process perspective. However, this research is still fragmented and lacks a systematic typology of the different types of HR attributions and a compelling organizing research framework. Furthermore, a number of research gaps and opportunities have emerged regarding the nomological net of employee HR attributions. To address the gaps and capitalize on the opportunities, the authors propose an overarching theory-driven multi-level framework that guides the choice of the antecedents and outcomes of employee HR attributions and explains their relationships along with both mediating and moderating mechanisms. Drawing on signaling theory embedded in the proposed framework, the authors identify and categorize various antecedents of employee HR attributions to explain their relationships. The authors also use several additional theories such as social exchange and the job demands–resources model included in their review to identify and categorize various outcomes of employee HR attributions across levels of analysis (i.e., individual, collective [team/group/unit], organization) and explain their relationships. In addition, the proposed framework explains how individual-level employee HR attributions emerge at the collective level and influence collective processes and outcomes. The authors end their review by pinpointing future research needs and discussing related future research directions.
