Prefabricated products are continually entering the building construction market; yet, the decision to use prefabricated products in a construction project is based mostly on personal preferences and the evaluation of direct costs. Researchers and practitioners have debated appropriate measurement systems for evaluating the impacts of prefabricated products and for comparing them with conventional on-site construction practices. The more advanced, cost–benefit approach to evaluating prefabricated products often inspires controversy because it may generate inaccurate results when converting non-monetary effects into costs. As prefabrication may affect multiple organisations and product subsystems, the method used to decide on production methods should consider multiple direct and indirect impacts, including nonmonetary ones. Thus, this study aims to develop a multi-criteria method to evaluate both the monetary and non-monetary impacts of prefabrication solutions to facilitate decision-making on whether to use prefabricated products.

Drawing upon a literature review, this research suggests a multi-criteria method that combines the choosing-by-advantage approach with a cost–benefit analysis. The method was presented for validation in focus group discussions and tested in a case involving a prefabricated bathroom.

The analysis indicates that the method helps a project’s stakeholders communicate about the relative merits of prefabrication and conventional construction while facilitating the final decision of whether to use prefabrication.

This research contributes a method of evaluating the monetary and non-monetary impacts of prefabricated products. The research underlines the need to evaluate the diverse benefits and sacrifices that stakeholder face when considering production methods in construction.

Sources highlight that insufficient skills of site supervisors considerably influence the progress of many construction projects in numerous countries. This study intends to identify the crucial supervisory competencies that influence the effectiveness of building project operations in the context of developing countries.

The crucial construction site supervisory competencies were qualitatively identified through a comprehensive literature survey and a series of expert interviews with the use of thematic analysis approaches. A questionnaire survey was then carried out among 154 building project firms to quantify the impacts of the competencies on the effectiveness of project tasks with the use of the relative importance index approach. Additionally, industry-consultative meetings were held using problem-focused communication strategies to scrutinise the necessary actions.

Overall, 22 cognitive elements and 24 skills/abilities of supervisors were determined as being critical according to their impact values, where the site supervisors cognitive domains in construction planning and construction materials were determined as the top-ranking competencies in the list, with their manual skills/abilities in labour management and labour performance evaluation. Accordingly, a group of key competency outcomes were produced for the considerations in developing new site supervisory training components. Relevant statistical analysis results and the industry consultative outcomes substantiated the validity and dependability of the overall results.

Although the study's focus was to site supervision procedures used in Sri Lankan building construction projects, the overall findings/outcomes might be put to the test in related situations in other emerging industries in other countries.

The study has constructed a base that shows how the significant site supervisory competencies influence the effectiveness of building construction operations, contributing to making a big difference in the methods of reskilling/upskilling in the industry associated with construction labour, supervision, efficiency management and productivity enhancement.

Given the importance of senior volunteers in an ageing society, this study aims to deepen the understanding of how seniors create well-being by volunteering as service providers in terms of motivations for volunteer participation and value co-creation/co-destruction in service provision.

Focussing on senior volunteers acting as service providers in the tourism sector, this study conducted a programme of qualitative research with 15 senior volunteer tour guides in Japan and the UK through the purposive sampling method. The data were analysed by the Gioia method to identify data structure and create a conceptual model.

Seniors start with a mixture of different motivations, not only symbolic and health ones. However, after a certain period of training, they become more aware of their volunteer role as service providers and may strive to maximise the benefits to their clients. The overall performance of such a role supports their well-being. They may also experience episodes of value co-destruction; such negative experiences may be overcome by building good relationships with their colleagues in the organisation.

The paper identifies organisational support ideas for senior service provider volunteers aimed at overcoming negative experiences and achieving well-being, in terms of training and improved communication between organisation members.

This study contributes to the transformative service research literature by constructing a model to showcase the relationship amongst expectations of volunteering as a service provider, service delivery and well-being creation. This paper also discusses the positive and negative effects of volunteer service delivery on senior volunteers' well-being.

Corporate real estate management (CREM) is complex due to an increasing number of real estate (RE) added values and the tensions between them. RE managers are faced with trade-offs: to choose a higher performance for one added value at the cost of another. CREM research mainly deals with trade-offs in a hypothetical sense, without looking at the characteristics of the RE portfolio nor the specific context in which trade-offs are made. The purpose of this paper is to further develop the concept of real estate value (REV) optimisation with regard to tensions between decreasing CO₂ emissions and supporting user activities.

Mixed method study. REV optimisation between user activities and energy efficiency for police stations in the Netherlands built between 2000 and 2020 is analysed. This is complemented by interviews with an RE manager and senior user of police stations and analysis of policy documents.

The characteristics of the police station portfolio indicate no correlation between user activities and energy efficiency for the case studied. This is complemented by interviews, from which it becomes clear that there was in fact little tension between supporting user activities and energy efficiency. The performances of these two different added values were optimised separately.

This study combines different scales (building and portfolio level) with different types of data: portfolio analysis, document analysis and interviews. This creates a comprehensive image of whether and how the Netherlands police optimised the two RE values.

To date, there are no studies in the literature that provide a comprehensive understanding of the interrelationships between the slenderness ratio and the main design criteria in supertall towers (=300 m). In this paper, this important issue was explored using detailed data collected from 75 cases.

This paper was carried out with a comprehensive literature review including the database of the Council on Tall Buildings and Urban Habitat(CTBUH) (CTBUH, 2022), peer-reviewed journals, MSc theses and PhD dissertations, conference proceedings, fact sheets, architectural and structural magazines and other Internet sources. In this study, the case study method was also used to gather and consolidate information about supertall towers to analyze the interrelationships. Cases were 75 supertall buildings in various countries [44 from Asia (37 from China), 16 from the Middle East (6 from Dubai, the United Arab Emirates), 11 from the United States of America and 3 from Russia, 1 from the UK].

The paper's findings highlighted as follows: (1) for buildings in the height range of 300–399 m, the slenderness ratio was usually between 7 and 7.9 and megatall towers were frequently built at a slenderness ratio of 10–15; (2) the median slenderness ratio of buildings in the 400–599 m height ranges was around 8.6; (3) a trend towards supertall slender buildings (=8) was observed in Asia, the Middle East and North America; (4) residential, office and mixed-use towers had a median slenderness ratio of over 7.5; (5) all building forms were utilized in the construction of slender towers (>8); (6) the medium slenderness ratio was around 8 for supertall buildings constructed with outriggered frame and tube systems; (7) especially concrete towers reached values pushing the limits of slenderness (>10) and (8) since the number of some supertall building groups (e.g. steel towers) was not sufficient, establishing a scientific relationship between aspect ratio and related design criteria was not possible.

To date, there are no studies in the literature that provide a comprehensive understanding of the interrelationships between the slenderness ratio and the main design criteria in supertall towers (=300 m). This important issue was explored using detailed data collected from 75 cases.

Academic work on responsible leadership has emphasised two aspects: the value orientation of leaders, and the scope of interests they consider in their leadership – the range of stakeholders, current and future, human and non-human. I address these via two questions that are equally important but different in scale: one is about the motives for individual action and the other about the coordination of multiple organisations. Possible answers are considered in the context of leadership development: the developmental pathways, and the structure of leader and leadership development programmes, that are most likely to promote responsible leadership.

On the question of moral motivation (drawing on the work of Paul Ricoeur) I suggest four influential factors: witnessing the suffering of others, admonitions of “masters of justice”, welfare of loved ones, and networks within which to discuss these matters. These I summarise as “the echo of conscience”.

On the question of coordinated change at a systemic level, I review several approaches commonly found in leadership development programmes, interpret these as emerging from four “logics” and consider the implications for responsible leader development. The four logics are: systems are so complex that entrepreneurial innovation is a primary mode of responsible leadership; specific issues might be resolved by bringing “the system in the room”; sector-specific organising to change the rules of the game towards greater social responsibility; identifying “positive tipping points” and seeking triggers for change.

I conclude with a meditation on idealism in responsible leadership.

This paper aims to understand how companies addressed and revisited their sustainable development goals (SDGs) engagement during COVID-19.

The study conducts semi-structured interviews with the sustainability managers of 16 Italian listed companies acting for the accomplishment of the SDGs. Then, the interviews’ transcripts and the companies’ sustainability reports were thematically analysed to tease out relevant findings.

The findings show that companies have intensified their SDGs efforts during COVID-19, implementing an approach closer to the “Sustainability for Braving Crisis”. The findings unveil the transformational mechanisms which determined and facilitated this improvement at three levels of the business SDGs engagement: “WHY” (general awareness and motivations), “HOW” (governance mechanisms, organizational structure and stakeholder dialogue) and “WHAT” (SDGs identification and prioritization and actions for the SDGs). These findings uncover the mechanisms through which a global crisis may prompt and catalyse sustainable business practices, acting as i) an inspirational and empowering event, ii) an organisational lever and iii) a reference point.

This research has important implications for practice and policy, as it offers managers and stakeholders guidance to understand how companies have reshaped their sustainability practices during the pandemic and drives future corporate responses in times of crisis.

This study shows that a crisis may be a powerful lever to intensify business sustainability practices towards a better contribution to the SDGs.

This study focuses on how companies have revised their SDGs practices when faced with a global crisis such as COVID-19.
