During the building designing, it is very important to deal with the fire resistance of the structures. The designed materials for escape routes should be selected to ensure the usability of the structures until the time of escape. Planning affects the glass structures similarly, so these can also be partition walls and load bearing structures, although the latter is less applied on escape routes. The heat protection of the glasses can be improved with heat-protective foils, while fire protection is provided by gel intumescent material.

To research the topic of fire resistance, laboratory experiments were carried out on small-scaled glass elements with thermal protection foil at Budapest University of Technology and Economics at the Department of Construction Materials and Technologies.

Fire protection of small model specimens was tested with blowtorch fire and furnace heat load. During the experiments, six foils were tested. Single pane glass, double layered and triple glazed specimens were tested with blowtorch fire.

Fire protection of small model specimens was tested with blowtorch fire and furnace heat load. During the experiments, six foils were tested. Single pane glass, double layered and triple glazed specimens were tested with blowtorch fire. In case of heat-protected glazing, the foils on the “protected” side of the single pane glass do not have a fire protection effect based on blowtorch fire test. For double glassed specimens, the P35 foil has a perceptible effect, even for the requirements of the flame breakthrough (E, integrity), when the foil is placed on the inner side (position 3) of the second glass layer. The stratification of each triple glazed specimens was effective against blowtorch fire load (3 M, S4&P35), so (EI, integrity and isolation) it can meet the requirements of flame breakthrough and thermal insulation.

The purpose of this paper is to explore an interesting complex infrastructure construction case study project in which the initiation/design and delivery phases were managed differently, with diverse assumptions and workplace culture. It uses a recently developed collaboration and relationship-based procurement taxonomy to analyse the decision to commence a project and to deliver the project. The taxonomy tool reveals underlying assumptions and helps explain actions taken. The paper provides a window into the decision-making process. It also illustrates levels of innovation applied at the design and delivery phases.

A case study was undertaken, primarily using recorded and transcribed interviews, with five key senior participants in the project. This gathered a client, designer and contractor perspective that was subsequently analysed using a sense-making approach.

It is possible to start a project adopting a highly collaborative approach that maximises innovation, understanding complexity and developing a design that can then be delivered using a more traditional approach. The taxonomy used demonstrates that it is a useful visualisation tool for this purpose.

The research was limited to the perspectives of only five individuals even though they were key decision-makers and had a robust overview of the project as a whole. The delivery phase was chosen as a matter of policy without the ability to break loose from that policy. The implications for beginning the initiation and design process in a highly collaborative hands-on mode influenced the understanding of all parties involved in the project in a positive direction. The case study was based in Australia, which has extensive experience of collaborative project delivery approaches.

The taxonomy and its ability to provide visualisation of the experienced collaboration presents a powerful tool in helping us understand how it may be useful and what limitations to collaboration exists.

The paper illustrates the value of social interactions as alliance forms tend to consider triple bottom line issues and stakeholder engagement more highly than traditional, transnational approaches to project design and delivery.

The case study was unusual in its technical complexity; however, the main value of the paper is the application of the taxonomy and visualisation tool as a way to better understand how a project is being managed from a collaboration perspective.

Robots are used in assembly lines because of their higher flexibility and lower costs. The purpose of this paper is to develop mathematical models and simulated annealing algorithms to solve the robotic assembly line balancing (RALB-II) to minimize the cycle time.

Four mixed-integer linear programming models are developed and encoded in CPLEX solver to find optimal solutions for small-sized problem instances. Two simulated annealing algorithms, original simulated annealing algorithm and restarted simulated annealing (RSA) algorithm, are proposed to tackle large-sized problems. The restart mechanism in the RSA methodology replaces the incumbent temperature with a new temperature. In addition, the proposed methods use iterative mechanisms for updating cycle time and a new objective to select the solution with fewer critical workstations.

The comparative study among the tested algorithms and other methods adapted verifies the effectiveness of the proposed methods. The results obtained by these algorithms on the benchmark instances show that 23 new upper bounds out of 32 tested cases are achieved. The RSA algorithm ranks first among the algorithms in the number of updated upper bounds.

Four models are developed for RALBP-II and their performance is evaluated for the first time. An RSA algorithm is developed to solve RALBP-II, where the restart mechanism is developed to replace the incumbent temperature with a new temperature. The proposed methods also use iterative mechanisms and a new objective to select the solution with fewer critical workstations.

In less than a decade to sustainable development goals (SDGs) there is a threat of household waste emanating from sub-urban sprawl especially in developing countries. Private approaches with government-enabling environments have been proved a successful platform for urban services such as housing provision and telecommunication in developing cities. Still private solid waste management (PSWM) seems different in Nigeria. Therefore, this paper aims to investigate the possible perceived hindrances facing PSWM organisations and proffer feasible policies to enhance sustainable clean and healthy cities.

Seven communities within Benin City sub-urban environs were adopted as the study area to accomplish the research’s objectives via a phenomenology type of qualitative research design. The study analysed the collated data from the knowledgeable participants via a thematic approach.

Lax legislative, absence of institutional framework, inadequate economic motivation, inadequate technical operations, among others, emerged as the encumbrances faced by PSWM firms. Wastes dumped along unethical locations such as streets, roads, uncompleted buildings, culverts and drainage channels, and undeveloped plots emerged as the encumbrance outcomes. Findings show that proffering feasible policy solutions to tackle identified hindrances can promote the achievement of SDGs across semi-urban locations in Nigeria.

This research is restricted to urban household waste management by PSWM within Nigeria. Also, the study identified the challenges and proffer policy solutions to enhance improved clean environment within the sub-urban and urban cities.

As part of this study’s implications, results from this research intend to guide government policymakers and PSWM firms to encourage collaboration in designing appropriate strategic and educational programmes for the householders (customers) in sub-cities. It will be achieved via feasible policies that are tailored towards achieving sustainable health and environment-friendly sub-urban locations.

This paper intends to enhance proper PSWM and create sustainable cities via collaboration. Also, the paper engaged key stakeholders via a qualitative research design to proffer possible solutions to the menace of sub-urban and urban household waste management.

The purpose of this study is to investigate existing and emerging technology-driven stressors using the transactional model of stress and coping (TMSC).

In-depth semi-structured interviews with 36 professionals were performed to obtain qualitative data to explore emerging techno-stressors. The findings were validated a year into the pandemic with human resource (HR) professionals.

The authors identify a previously unreported techno-stressor, Techno-Isolation (TIS), which arises from a heavy dependence on information communication technologies for professional social interactions. Additionally, several considerations of interaction characteristics are identified that, based on the platform used, affect the experience of TIS, further expanding the TMSC with the addition of medium-interaction compatibility. The authors present a testable model and discuss implications.

This study identifies three new information communication technology (ICT)-based antecedents leading to a new techno-stressor, as well as the importance of medium-interaction compatibility in the experiences of stressors as strains. The authors discuss how these elements fit with and extend the existing stress literature.

The increasing growth of urbanisation, especially in developing countries, coupled with affordable housing leakages, may thwart achieving Sustainable Development Goal (SDG) 11 (sustainable cities and communities). Studies regarding affordable housing leakages and their aftermath to Goal 11 in one study are scarce in Malaysia. The study investigated Malaysia's low-cost housing (LCH) leakages and their aftermath to Goal 11 and proffered measures to achieving Goal 11 and its targets. The purpose of this paper is to address these issues.

The researchers covered four of Malaysia's major cities via a qualitative approach. The study used 40 participants via semi-structured virtual interviews, and saturation was achieved. The study adopted a thematic approach for the collected data and honed them with secondary sources.

Findings group Malaysia's LCH leakages into government/agencies/departments in housing, housing developers/building contractors and client/building owners' root causes in Malaysia's context. It shows a threat from Malaysia's LCH leakages to achieving Goal 11 and proffered measures to enhance achieving Goal 11. Achieving Goal 11 will strengthen and improve Malaysia's many SDGs accomplishments because of their link.

Apart from proffering measures to mitigate long-standing issues (leakages) in Malaysia's LCH delivery from achieving Goal 11, findings will stipulate the accomplishment of other SDGs related to housing delivery.

Digital uptake amongst construction organisations is described as slow and ineffective, undermining a fundamental transformation and limiting construction firms from exploiting the digital benefits. In this space, meaningful research that utilises a qualitative approach in pursuit for employees' insights towards digital transformation is lacking. Such limited focus from previous efforts presents an opportunity to illuminate the determinants of an effective digital transformation that are, arguably, responsible for the status quo of low digital uptake in the construction sector. This paper aims to discuss the aforementioned idea.

This study adopts a qualitative approach to address the literature's digital discreetness in construction. The qualitative approach captures employees' perspectives through its unbounded characteristic of encouraging illustration and discussion.

This paper captures 35 digital transformation determinants under three clusters, namely, organisation related, i.e. hierarchy, size and management, people related, i.e. team orientation, training and knowledge and leadership related, i.e. awareness, attitude, approach and leaders' characteristics. Findings suggest a new set of arguments in relation to understudied factors and their influence on the digital uptake in construction organisations.

This paper offers empirical indication of the determinants believed to influence an effective digital transformation in construction organisations. Such conceptualisation is crucial and is depicted as perceived by construction employees and practitioners, which is a less biased approach than that of comparable studies that argue the viewpoints of industry leaders in isolation of other members of the hierarchy.

This paper aims to explore the implications of integrating humanoid service robots into hospitality service encounters by evaluating two service prototypes using Softbank Robotics’ popular service robot Pepper™: to provide information (akin to a receptionist) and to facilitate order-taking (akin to a server). Drawing both studies together, the paper puts forward novel, theory-informed yet context-rooted design principles for humanoid robot adoption in hospitality service encounters.

Adopting a multiple method qualitative approach, two service prototypes are evaluated with hospitality and tourism experts (N = 30, Prototype 1) and frontline hospitality employees (N = 18, Prototype 2) using participant observation, in situ feedback, semi-structured interviews and photo-elicitation.

The adoption of humanoid service robots in hospitality is influenced by the following four layers of determinants: contextual, social, interactional and psychological factors, as well as extrinsic and intrinsic drivers of adoption. These empirical findings both confirm and extend previous conceptualizations of human-robot interaction (HRI) in hospitality service.

Despite using photo-elicitation to evoke insight regarding the use of different types of service robots in hospitality, the paper mostly focuses on anthropomorphized service robots such as Pepper™.

Adopting humanoid service robots will transform hospitality operations, whereby the most routine, unpleasant tasks such as taking repeat orders or dealing with complaints may be delegated to service robots or human-robot teams.

Working with and receiving service from Pepper™ changes the service encounter from direct practical, technical considerations to more nuanced social and psychological implications, particularly around feelings of self-esteem, social pressure and social judgment.

This paper presents one of the first empirical studies on HRI in hospitality service encounters using Softbank Robotics’ Pepper™. In doing so, the paper presents a novel framework for service robot adoption rooted in first-hand user interaction as opposed to previous, theory-driven conceptualizations of behavior or empirical studies exploring behavioral intention.

The purpose of this paper is to identify, classify and analyse temporality in information systems development (ISD) literature.

The authors address the temporality and ISD research gap by using a framework – which classifies time into three categories: conceptions of time, mapping activities to time and actors relating to time. The authors conduct a systematic literature review which investigates time in ISD within the Senior Scholars' Basket, Information Technology & People (IT&P), and top two information systems conferences over the past 20 years. The search strategy resulted in 9,850 studies of which 47 were identified as primary papers.

The results reveal that ISD research is ill equipped for contemporary thinking around time. This systematic literature review (SLR) contributes to ISD by finding the following gaps in the literature: (1) clock time is dominant and all other types of time are under-researched; (2) contributions to mapping activities to time is lacking and existing studies focus on single ISD projects rather multiple complex ISD projects; (3) research on actors relating to time is lacking; (4) existing ISD studies which contribute to temporal characteristics are fragmented and lack integration with other categories of time and (5) ISD methodology papers lack contributions to temporal characteristics and fail to acknowledge and contribute to time as a multifaceted interrelated concept.

This work has developed the first SLR on temporality in ISD. This study provides a starting point for ISD researchers and ISD practitioners to test commonly held temporal assumptions of ISD researchers and practitioners.
