Green roofs are strategies for the ecological intensification of cities and a measure of meeting some of the sustainable development goals (SDGs). They have widely been adopted as an adaptation strategy against an urban heat island (UHI). However, they are conventionally soil-based making it difficult and expensive to adopt as a strategy for greening existing buildings (GEB). This paper, therefore, develops a novel green roof system using climbers for thermal-radiative performance. The paper explores the vitality of climbing species as a nature-based strategy for GEB, and for the ecological improvement of the predominantly used cool roofs in sub-Saharan Africa (SSA).

Simulation for the same building Kejetia Central Market (KCM) Redevelopment; the existing aluminium roof (AL), soil-based extensive green roof (GR1) and the proposed green roof using climbing plants (GR2) were performed using ENVI-met. The AL and GR1 were developed as reference models to evaluate and compare thermal-radiative performance of the conceptual model (GR2). The long wave radiation emission (Q_lw), mean radiant temperature (MRT) and outdoor air temperature (T_a) of all three roofing systems were simulated under clear sky conditions to assess the performance and plant vitality considering water access, leaf temperature (T_f) and latent heat flux (LE₀) of GR1 and GR2.

There was no short wave radiation (Q_sw) absorption at the GR2 substrate since the climbers have no underlying soil mass, recording daily mean average Q_lw emission of 435.17 Wm⁻². The soil of GR1, however, absorbed Q_sw of 390.11 Wm⁻² and a Q_lw emission of 16.20 wm⁻² higher than the GR2. The AL recorded the lowest Q_lw value of 75.43 Wm⁻². Also, the stomatal resistance (r_s) was higher in GR1 while GR2 recorded a higher average mean transpiration flux of 0.03 g/sm³. This indicates a higher chance of survival of the climbers. The T_a of GR2 recording 0.45°C lower than the GR1 could be a good UHI adaptation strategy.

No previous research on climbers for green roof systems was found for comparison, so the KCM project provided a unique confluence of dynamic events including the opportunity for block-scale impact assessment of the proposed GEB strategy. Notwithstanding, the single case study allowed a focussed exploration of the novel theory of redefining green roof systems with climbers. Moreover, the simulation was computationally expensive, and engaging multiple case studies were found to be overly exhaustive to arrive at the same meaningful conclusion. As a novelty, therefore, this research provides an alternative theory to the soil-based green roof phenomenon.

The thermal-radiative performance of green roofs could be improved with the use of climbers. The reduction of the intensity of UHI would lead to improved thermal comfort and building energy savings. Also, very little dependence on the volume of soil would require little structural load consideration thereby leading not only to cheaper green roof construction but their higher demand, adoption and implementation in SSA and other low-income economies of the global south.

The reduction of the consumption of topsoil and water for irrigation could avoid the negative environmental impacts of land degradation and pollution which have a deleterious impact on human health. This fulfils SDG 12 which seeks to ensure responsible consumption of products. This requires the need to advance the research for improvement and training of local built environment practitioners with new skills for installation to ensure social inclusiveness in the combat against the intractable forces of negative climate impacts.

Climbers are mostly known for green walls, but their innovative use for green roof systems has not been attempted and adopted; it could present a cost-effective strategy for the GEB. The proposed green roof system with climbers apart from becoming a successful strategy for UHI adaptation was also able to record an estimated 568% savings on topsoil consumption with an impact on the reduction of pollution from excavation. The research provides an initial insight into design options, potentials and limitations on the use of climbers for green roofs to guide future research and experimental verification.

This paper aims to investigate the combined effect of airline service quality (ASQ), loyalty programme and perceived value (PV) on word-of-mouth (WOM) behavior of passengers’ traveling to domestic and international destinations from India.

Passenger’s perception on service quality, loyalty programme and PV varies with flight type, which can affect WOM. This study was designed to know whether destination based difference in passengers’ perception on airline services affects their WOM. Hence, a sample of 554 frequent passengers was taken, which includes 358 domestic and 196 international passengers. The responses were collected using well-structured questionnaire. The hypothetical model was developed and tested using structural equation modeling using analysis of a moment structures (AMOS).

Travel destination (flight) type moderates significantly the effect of ASQ on WOM behavior. ASQ affects WOM behavior more in domestic passengers. PV and loyalty programme do not moderate significantly with respect to destination type. PV was found to have significant influence on international passengers. However, loyalty programme was significant among domestic passengers.

Airline managers can develop appropriate marketing strategies targeting the passenger influencing attributes. ASQ is the most significant attribute applicable to both flight types. The airlines can focus on attractive ticket fares for international passengers and more loyalty programme benefits for domestic passengers.

This study examined the combined effect of ASQ, loyalty programme and PV on WOM behavior of passengers traveling in domestic and international sectors, which has not been researched yet.

The purpose of this study is to analyse the perception of employees towards training and also examine the mediation effect of employee engagement between training and task performance.

An integrated model has been developed highlighting the relationship of the motivation for training and support for training and their implications on task performance through the mediating role of employee engagement. Using the sample of 397, structural equation modelling has been used with the help of SPSS and AMOS to validate the hypothesized relationship and evaluate the responses of employees working in travel agencies operating in Delhi (capital), India.

The findings of this study demonstrated a positively significant relationship between training and task performance of employees in the tourism and hospitality industry. Simultaneously, employee engagement positively mediates the relationship between training and task performance directly and indirectly. This study goes over the ramifications of the findings and offers some suggestions for practical implementations.

The findings of this study can be used by managers and HR professionals to organize exclusive training programs for improving employees’ performance based on the dimensions used in this study. This study also suggests that training program enhances employee engagement in organizational activities which leads to build up team work and overall organizational as well as individual performance.

This study also introduces a conceptual model and theoretical framework that provide a significant contribution to the training and task performance of employees. This study provides a strong theoretical foundation by incorporating the social exchange theory to confirm the role of employee engagement in performance. Further, this novel piece of research explores the relationship between training and task performance with employee engagement as a mediator, especially in the Indian tourism and hospitality industry.

This study aims to examine the direct and indirect effects of organizational culture (OC) and total quality management practices (TQMPs) on the relationship between green practices (GPs) and sustainability performance (SP) by using structural equation modeling (SEM) analysis.

This study proposed a conceptual research model of the relationships and formulated six hypotheses. This study used a structured questionnaire based on previous studies to collect relationship data to test these hypotheses, and 441 full-time managers from various US businesses responded. The complete and valid survey responses were then tested against the hypotheses using IBM SPSS Statistics and SEM-AMOS.

Results supported the relationships proposed in the research model. They indicated that a strong supporting OC and TQMPs might improve positive SP and GPs. Additionally, the more managers are aware of their companies' GPs, the more likely they will feel positive about the organization's SP.

A larger sample size to ensure statistically minimum representation in several major industries would better validate the findings and help identify significant differences in industry-specific OCs, TQMPs, GPs and SPs. Similarly, ensuring a varied geographical representation (both within the USA and internationally) would help determine if the findings vary according to the respondent's location. Furthermore, collecting the data during Year 1 of the COVID-19 pandemic may have skewed the results. Thus, once the working environment has been normalized, the survey should be repeated to determine if the findings are valid post-pandemic.

The findings of this study provide important strategic guidance for managers who work to balance the implementation of corporate GPs and the triple bottom line dimensions of SP. For practitioners, the results showed that companies could accomplish both profitability and sustainability if they are willing to continuously pay attention to environmental issues and strategically invest in cost-efficient and eco-friendly initiatives.

To the best of the authors’ knowledge, this research is one of the first to explore how OC and TQMPs, directly and indirectly, affect the relationship between GPs and the triple bottom line dimensions of SP. These results imply that OC and TQMPs have a significant indirect impact on the relationship between GPs and the SP dimensions.

The purpose of this study is to examine the direct and indirect effects of organizational culture and quality improvement practices on the relationship between green practices and sustainability performances by using the structural equation modeling (SEM) approach.

Structured questionnaires were used to collect data from 330 full-time managerial employees in established businesses. The relationships depicted in the proposed conceptual model were tested through six hypotheses. IBM SPSS Statistics and SEM-AMOS were used to test the hypotheses.

The results supported proposed relationships in the model, except the one between organizational culture and green practices. The findings indicate that the more employees are aware of companies’ green practices, the more likely they are going to feel positive about the sustainability performance of the organization. Additionally, a strong organizational culture that supports the green movement and quality improvement practices lead to positive sustainability outcomes.

A larger sample size in several major industries would allow the development of industry-specific sustainability strategies and best practices. In addition, a study based in a different geographical location in the USA or in a different country is recommended to see if the findings can be generalized across different industries, geographical locations or countries.

Sustainability has undoubtedly become a major concern for many companies today. The findings of this study provide important guidelines for practitioners to balance the implementation of green practices, organizational culture, quality improvement practices and sustainability performance dimensions. Profitability and sustainability can be achieved together when companies are willing to continuously pay attention to environmental issues and strategically invest in initiatives that are cost-efficient and eco-friendly.

This study is one of the first that explores how organizational culture and quality improvement practices affect directly and indirectly the relationship between green practices and sustainability performance. The results imply that organizational culture and quality improvement practices significantly affect the relationship between green practices and the sustainability performance dimensions.

Although scaling is considered a “hot topic”, very little is known about how knowledge management (KM) assists in scaling social impact. To fill this gap, the authors draw on knowledge-based and social capital theories and investigate how various KM practices and external networks (e.g. bridging social capital) affect scaling social impact in developing countries.

Applying structural equation modeling (SEM) with AMOS version 23, the authors conducted a survey with 354 women leaders who are working in women-led social enterprises in Dhaka, Bangladesh.

The authors found that knowledge codification, training and mentoring, and bridging social capital are positively and significantly associated with scaling social impact.

This is one of the pioneering study that explore how KM impacts scaling social impact for women-led social enterprises in the context of a developing country. The authors also extend knowledge-based theory by applying it at the individual level. Finally, the authors enhance the understanding of women entrepreneurship by showing that women entrepreneurs in developing countries are also utilizing bridging social capital to overcome challenges associated with scaling social impact.

The purpose of this paper is to propose the sustainable housing (SH) model for the housing of Region-one of Mashhad city in Iran.

Building the SH particularly increases mitigation measures as well as creates healthier environments for inhabitants by decreasing harmful environmental and physical effects. This research in terms of the target is applied research that has been done with the descriptive-analytical method. The research population is residents who live in the Region-one of Mashhad, with a statistical sample of 384 people. The responses were collected from the questionnaire, and structural equation modeling (SEM) was employed to illustrate the research SH model in AMOS software.

The findings indicate that the suitability of the housing model with meeting needs together with the quality of the health situation in housing has the most influences, and in contrast, the number of residential units with building permits besides the amount of home green space has the least influences on the sustainability of housing in the region.

The results can offer valuable insights for helping the sustainability of housing in the studied area and similar cases, which may vary in a different context.

The new aspect of the study is to provide the SH model by SEM, which has not been investigated in almost all previous research. This paper makes a contribution to the understanding of the physical and environmental components that affect the sustainability of housing in Region-one of Mashhad city in Iran according to respond to the needs of both lifestyles: pilgrims-tourists and residents. The results can also contribute to housing stabilizing in other developing countries, especially the pilgrimage and tourism countries.

The aim of this study is to investigate the extent to which organizational justice (OJ) mediates between responsible leadership (RL) and employee turnover intention (TI).

Both online and offline questionnaire was used to collect the data from 387 Indian health-care employees, and the data were analyzed using partial least squares structural equation modeling (PLS-SEM) with the help of SmartPLS 4.

The study’s findings demonstrated a significant positive association between RL and OJ and a negative association between OJ and employee TI. Furthermore, results also confirmed the mediating role of OJ between RI and TI.

The generalizability of the study‘s data collection is limited because it is based on the responses of Indian health-care sector employees to an online and offline survey. The authors propose that the health-care sector uses RL as an approach that takes a broad view of the parties with a stake and focuses on creating fairness in acts and justice at the workplace to address the major issue of employee turnover.

This study expanded on previous research by demonstrating that the influence of responsible leadership on employee TI is mediated by OJ in the context of India’s health-care sector. It also contributes to the literature regarding RI, OJ and TI. The study also enriched the body of knowledge about using the PLS-SEM approach to predict employee TI.

This study examines the direct and indirect effects of organizational environmental orientation (EO)/culture, quality management practices (QMP) and sustainability experience (SE) on the relationship between organizational green practices (GP) and the triple bottom line (TBL) of sustainability performance (SuP).

To test the seven hypotheses, a structured questionnaire was used to collect data. The responses of 365 managers from various USA businesses in the service industries were analyzed using IBM SPSS and structural equation modeling (SEM)-AMOS.

The empirical results indicate that positive SuP in the economic, environmental and social dimensions and organizational GP can be improved by a strong culture of EO, effective QMP and substantial SE.

This research fills the gap in existing research between important organizational and environmental priorities and SuP. Consequently, the study provides managers with important strategic guidance: for environmental practices to achieve profitability and sustainability success, companies must promote an environmental-mindful culture and strategically invest in integrated QM systems.

This research is one of the first that explores how organizational environmental culture and QMP affect directly and indirectly the relationship between GP and SuP. These results provide empirical evidence to support the claim that environmental culture and QMP have significant direct and indirect effects on the relationship between GP and SuP dimensions.

This study aims to establish a rigorous model that can pragmatically evaluate the facilities management (FM) performance of hospitals.

Among the applicable performance indicators that were identified from extant literature, a focus group study shortlisted ten key performance indicators (KPIs) in four categories (safety, physical, financial and environmental) and verified their practicality. Using the analytic network process (ANP) method to process the focus group’s responses yielded importance weightings for the KPIs and developed the intended evaluation model. This model was then validated by a case study.

From the empirical data collected, two types of FM performance data and two scenarios of KPI scores were identified. To process these data and scores, a robust calculation method was devised and then proved useful in obtaining an overall score for holistic hospital FM performance. The case study confirmed the appropriateness and validity of the model developed.

Through illustrating how the ANP method could be applied to develop an FM performance evaluation model, the study contributes knowledge to the multi-criteria decision-making domain. Despite the geographical limitation of the model established (i.e. centered around a group of hospitals investigated in Hong Kong), the study can serve as a reference for developing performance evaluation models for other buildings or infrastructures globally.

The model constitutes a practical tool for evaluating the FM performance of hospitals. Using this model on a regular basis will enable performance benchmarking and hence, continuous improvement of FM services.

The ANP model established is the first of its kind tailored for evaluation of hospital FM performance.
