Abstract
After a technocratic period predominating in mobility literature and practice, the rhetoric of participation has been incorporated as a vital condition for the sustainable mobility agenda and, more recently, for achieving transport and mobility justice. Considering the social significance of mobility beyond simple movement and participation as a term that can accommodate a wide range of motivations and implications, this chapter explores the complex interplay of participation and mobility in the global south context. To this end, this study adopts the spaces for participation framework to investigate the multiple roles of participation in urban mobility. With a focus on the Brazilian context, this chapter uncovers the nature, dynamics, and reach of invited and claimed spaces for participation in mobility planning. Using Rio de Janeiro as the case study site, the chapter examines the invited spaces for participation enabled by the city's mobility plan and analyses whether marginalised populations engage with and/or create further spaces for participation. This was achieved through document analysis, online photo-elicitation interviews with residents of Favela Santa Marta as well as semi-structured interviews with municipal government professionals and representatives of non-government organisations involved in the development of Rio's mobility plan. The chapter discusses the interconnectedness or lack of, within invited and claimed spaces for participation and the multiplicity of meanings attributed to participation and mobility by different actors. The chapter closes with a reflection on what this means for participatory mobility planning in Brazil but which may apply to similar regions in the global south.

Abstract
Purpose
The aim of this research study is to develop a risk-based framework that can quantify maintainability to forecast future maintainability of a building at early stages as a decision tool to minimize increase of maintenance cost.
Design/methodology/approach
A survey-based approach was used to explore the risk factors in the domain of maintainability risks under tropical environmental conditions. The research derived ten risk factors based on 58 identified causes related to maintainability issues as common to high-rise buildings in tropical conditions. Impact of these risk factors was evaluated using an indicator referred to as the “maintenance score (MS)” which was derived from the “whole-life maintenance cost” involved in maintaining the expected “performance” level of the building. Further, an ensemble neural network (ENN) model was developed to model the MS for evaluating maintainability risks in high-rise buildings.
Findings
Results showed that predictions from the model were highly compatible and in the same order when compared with calculations based on actual past data. It further showed that, maintainability of buildings could be improved if the building was designed, constructed and managed properly by controlling their maintainability risks.
Originality/value
The ENN model was used to analyze maintainability of a high-rise building. Thus, it provides a useful tool for designers, clients, facilities managers/maintenance managers and users to analyze maintainability risks of buildings at early stages.

Abstract
Purpose
The factors contributing to maintenance cost include the life‐long environmental factors that the building is exposed to during its useful life as well as parameters relating to the design, construction and maintenance processes. The performance of risk associated with these factors decides the future maintenance requirements of buildings. Ignoring these risks factors generally result in high maintenance costs. The purpose of this paper is to identify the maintainability risk factors and their implications on maintenance costs.
Design/methodology/approach
A survey based methodology was used to establish the risks factors of building maintainability. A sample of high‐rise buildings was selected to evaluate these risk factors that were identified through an extensive literature review and survey of substantive experts. Further, these risks factors were applied to a real case study.
Findings
A total of ten risk factors of maintainability were identified in relation to high‐rise buildings. They were analyzed using a case study and the implications on maintenance cost were evaluated. The results show that there is a considerable reduction in maintenance cost when these risks are minimized.
Research limitations/implications
The research was limited to the USA and its six biggest cities. The results presented are predominantly qualitative and the results rely on extensive evaluation.
Originality/value
The paper provides useful information to the designers and users on the maintenance problems related to buildings. Also it highlights critical risk conditions that should be considered to minimize maintenance costs.

Abstract
Purpose
Artificial neural network (ANN) has been used for risk analysis in various applications such as engineering, financial and facilities management. However, use of a single network has become less accurate when the problem is complex with a large number of variables to be considered. Ensemble neural network (ENN) architecture has proposed to overcome these difficulties of solving a complex problem. ENN consists of many small “expert networks” that learn small parts of the complex problem, which are established by decomposing it into its sub levels. This paper seeks to address these issues.
Design/methodology/approach
ENN model was developed to analyze risks in maintainability of buildings which is known as a complex problem with a large number of risk variables. The model comprised four expert networks to represent building components of roof, façade, internal areas and basement. The accuracy of the model was tested using two error terms such as network error and generalization error.
Findings
The results showed that ENN performed well in solving complex problems by decomposing the problem into its sub levels.
Originality/value
The application of ensemble network would create a new concept of analyzing complex risk analysis problems. The study also provides a useful tool for designers, clients, facilities managers/maintenance managers and users to analyze maintainability risks of buildings at early stages.

Abstract
Purpose
The information technology (IT) outsourcing (ITO) decision is a key issue in strategic and operational management and is considered a main critical factor influencing successful organizational performance and technology assessment. The purpose of this paper is to propose a framework combining value-focused thinking (VFT) methodology and the FITradeoff method to support decisions regarding ITO.
Design/methodology/approach
This study answers the following questions: How to identify, in a structured way, the objectives that should be considered in an ITO decision process in a changing environment? How to identify new IT services to be outsourced from the established objectives? The VFT method is recommended in this case to structure and model the problem. Moreover, the FITradeoff multicriteria method was considered in this study to support the evaluation and prioritization of IT services in an ITO decision
Findings
The framework provides promising results for ITO decisions. This study revealed that a lack of strategic and fundamental objectives is a critical issue in making ITO decisions. Although the VFT methodology is subjective in nature, it promotes a better understanding of goals and values, and FITradeoff allows the decision-maker to make comparisons of consequences based on his/her preferences.
Research limitations/implications
The recommendations of the study are restricted to the case study and cannot be generalized. In addition, applying the method requires attention in determining the criteria used for outsourcing IT.
Practical implications
The strategic analysis of ITO provides a holistic view of the current situation since (i) the VFT methodology enables the IT manager to generate new alternatives to assist future decisions and (ii) FITradeoff has been demonstrated as a suitable option to evaluate ITO decisions.
Originality/value
To the best of our knowledge, this is the first paper to utilize a problem structuring method (VFT) to identify criteria and alternatives based on the organizational values and objectives. This is integrated with a multicriteria method that uses partial information and may consequently lead to fewer inconsistencies (FITradeoff) in the context of ITO.

Abstract
Purpose
The purpose of this paper is to identify enablers for setting up relationally integrated value networks (RIVANS) for total facilities management (TFM) as a holistic approach to bridge the Project Management (PM) phase to the facilities management (FM) phase, aiming for better service delivery while optimizing the life-cycle cost. These enablers are proposed as required driving forces for the industry to bridge current gaps through RIVANS for TFM so as to improve the value of the facility and deliver better value to its stakeholders over its life span.
Design/methodology/approach
A literature review elicited 11 typical better values that could be achieved by suitably linking the PM and FM supply chains in general. While these were tested in parallel research exercises in Hong Kong, the UK and Singapore, this paper reports on the specific findings from Sri Lanka, where a Web-based questionnaire survey was conducted to identify potential better values for proposed relational networks (including the clients, consultants, contractors and suppliers in the supply chain). Better values were then clustered under principal domains/components using factor analysis to establish synergetic enablers.
Findings
In total, 11 significant better values for TFM were identified and four enablers were extracted as building long-term integrated networks, establishing a common resource pool linking PM and FM, enhancing sustainability of TFM and developing a similar protocol between PM and FM.
Originality/value
The study carried out in this paper contributes to knowledge by identifying drivers to bridge the gap between PM and FM to best achieve clients’ long-term aspirations through a holistic life-cycle approach. Furthermore, all stakeholders in TFM can revisit their practices to establish and strengthen the identified enablers.

Abstract
Purpose
This chapter proposes a conceptualization of joyful leadership as a unique leadership style and identifies a future research agenda to further explore the concept. While the concept of joyful leadership appears repeatedly in the nonacademic literature, including in blogs, vlogs, and podcasts, there is limited reference to joyful leadership in the academic literature highlighting a lack of academic rigor around the concept. Joyful leadership is proposed as a unique leadership style with specific patterns of behavior demonstrated by the leader. This research draws on understandings of emotion, positive affect, and leadership in the academic literature to develop a conceptualization of joyful leadership.
Design
The proposed conceptualization is based on an extensive literature review drawing from both the leadership field and the study of emotions including various theoretical perspectives from these diverse fields.
Findings
Based on discrete emotion theory a conceptualization of joyful leadership as a unique leadership style is presented, identifying key patterns of behavior associated with joyful leadership including discrete autonomic patterns, actions, nonverbal signals, and identified feelings.
Value
This research outlines a conceptual model to provide an understanding of the concept of joyful leadership as a unique leadership style. It draws on the current study of emotion, positive affect, and leadership and more specifically examines the concept of joyful leadership aligned to discrete emotion theory. This particular theory of emotion, when examined in relation to leadership, provides a basis for the concept of joyful leadership as a leadership style and the basis for its proposed characteristics and outcomes.

Abstract
This paper discusses some important findings from a research project on the maintainability of wet areas of high‐rise non‐residential, buildings. The implications of six key factors of maintainability namely water‐tightness, spatial, integrity, ventilation, material and plumbing on the occurrence of 14 most common defects found in wet areas were evaluated. Problem areas evaluated include water leakage from ceiling, staining/discolouration, paint defects, cracking/spalling of concrete, cracking/debonding of tiles, fungi/algae growth, pipe leakage and corrosion. An industry wide survey was conducted and the factors including workmanship, design detailing, maintenance and material incompatibility under tropical conditions are identified and discussed.

Abstract
Purpose
The booming social media attracts construction professionals (CPs) to express emotions caused by work pressure (WP) through online behaviors. Previous works focus on the analysis of WP and emotions but do not adequately consider how WP can be reflected through online emotions. Thus, this study aims to attempt to explore the quantitative relationship between online emotional intensity and WP.
Design/methodology/approach
This study developed a linguistic-sticker (LS) model to quantitatively evaluate the sentiment intensity of posts published on social media. Moreover, the authors designed two econometric models of ordinary least squares regression and negative binomial regression to test the hypothesis.
Findings
The research found that posts with stronger negative sentiment (or positive sentiment) indicate that CPs face higher (or lower) WP. Besides, there is a negative bias between the sentiment intensity of posts and the comment quantity.
Practical implications
The positive correlation between sentiment intensity of posts and WP has been confirmed, which indicates that construction managers should pay more attention to CPs' behavior on social media, and take a more direct way to analyze work-related online behavior (e.g. posting, commenting). The dynamic monitoring of emotion-related posts also provides a direct basis for the management team to learn about CP's pressure status and propose measures to reduce their negative emotions. Furthermore, the emotional posts published by CPs on social media provide a direct basis for team managers to obtain their psychological state.
Originality/value
The research contributes to incorporating CPs' emotions into the LS model and to providing information systems artifacts and new findings on the analysis of WP and online emotions.

Abstract
Purpose
This study aims to illustrate the potential of the many centuries-old universities buildings, in European cities, in a historical, architectural, aesthetic and symbolic dimension to diversify and differentiate urban tourist destinations supply.
Design/methodology/approach
This is a qualitative study supported by the analysis of public and classified documents, for which the main source is based on webography, and by conducting interviews.
Findings
The deficit of cultural tours, in the dimension of built heritage, is identified as one of the weaknesses of the city of Porto, as tourist destination, to be overcome. The interviewees are unanimous in recognizing the cultural, architectural and aesthetic impact of the historic buildings of the University of Porto, and most of them strongly agree with the integration of this legacy into the tourist offer of the city. The strategic sense of the heritage is emphasized, because of its location in charismatic areas of the city. The practice of effective networking, however, falls short of what is required to achieve ambitious and consistent objectives.
Research limitations/implications
The practice of effective networking, however, falls short of what is required to achieve ambitious and consistent objectives.
Originality/value
Emphasis is placed on the cities’ built heritage as a type of heritage that defines their uniqueness. The dissemination of cultural itineraries, which allows tourists and the community itself a broader and deeper cultural knowledge, contributes to the effective understanding of historic cities’ tourism. Given the scarcity of studies on the relationship between historic university buildings and tourism, the relevance of research focuses on highlighting the contribution of these cultural elements, through a network-based dynamic, to urban tourism destinations’ attractiveness. In particular, the University of Porto's potential for the integration of structured tourism products that contribute to the diversification and differentiation of the city of Porto as a destination is illustrated.
