Drawing on social information processing theory (SIP), this paper examines whether and how humble leadership affects employees' service improvisation (ESI) in the hospitality industry. Further, the study investigates the mediating role of psychological safety and the moderating role of creative self-efficacy (CSE).

To test the proposed relationships, the study adopts a cross-sectional design, administering questionnaires to 456 frontline staff in Egypt’s hospitality industry across three main sectors: restaurants, hotels and travel agencies. SPSS 27 and AMOS 22 were used for statistical analysis.

The study reveals a positive relationship between humble leadership and ESI, partially mediated by psychological safety. Furthermore, CSE not only strengthens the relationship between psychological safety and ESI but also enhances the indirect effect of humble leadership on ESI via psychological safety.

The study offers valuable insights for practitioners in the hospitality industry. To boost ESI, organizations can incorporate humble leadership attributes into their leadership development programs. Fostering a psychologically safe workplace would facilitate the positive impact of humble leadership on ESI. Recognizing CSE as a pivotal moderator underscores the importance of strategically selecting and developing employees with high CSE. These insights aim to cultivate a more service-oriented and effective workforce in the hospitality industry.

This study significantly contributes to leadership research in the hospitality industry by uncovering a previously unexplored link between humble leadership and ESI. Exploring psychological safety as a mediator and CSE as a moderator enhances our comprehension of how and when humble leadership influences ESI.

Given the regional diversity in China, this study aims to provide an empirical evaluation of how organizational stakeholders (i.e. customers, employees, suppliers and shareholders) affect corporate environmental sustainability investment (ESI).

To empirically investigate the influence of organizational stakeholders on ESI, this study used regional-level data consists of Chinese A-share stocks for the years 2009–2019.

This study’s findings show that pressure from customers, employees and suppliers has a significant effect on corporate ESI, with customers being the most important stakeholder group. Shareholders, by contrast, have no significant influence on ESI. The influence of these pressures is more pronounced in developed regions (the east) than in less developed (the west) localities of China.

This study complements the stakeholder–institutional perspective by implying to consider the differentiated logics of the contesting stakeholders in the nonmarket operations.

Practically, this study poses that managers must realize the heterogeneity of pressures from stakeholders and the differentiated impact of these pressures keeping in view the institutional differences in different regions.

Our study reports initial empirical evidence that shows how regional differences influence the role of stakeholders in determining corporate environmental strategy.

Works procurement performance is critical to successful project delivery. However, early supplier involvement (ESI) has been touted in other industries to impact procurement performance positively. Works procurement has been attracting significant attention from major players due to poor performance characterized by poor performance, budget overruns and incompetence. Hence, the purpose of this study was to assess the impact of ESI on public works procurement performance.

Based on a thorough review of the literature for a pilot survey, the main questionnaires were administered to 103 public procurement officers. To assess the impact of ESI on public works procurement performance, three constructs that served as factors for implementing ESI and five that measure works procurement performance were validated using partial least square structural equation modelling (PLS-SEM).

The outcome of this study shows a significant positive impact of ESI on works procurement performance. This included communication, trust and supplier capabilities. The study further showed that even though cost, schedule, quality, health and safety are essential, sustainability measures are also crucial for work procurement.

The results of this study could help firms make better decisions regarding public works procurement by encouraging ESI. This will likely significantly impact the successful project delivery and preservation of sustainability and efficiency objectives.

The application of PLS-SEM analysis in this study provides insights into how ESI can impact the procurement of public works in Ghana.

The aim of this paper is to develop a framework to enhance building maintainability through facilitating early suppliers’ involvement (ESI) in the design process.

A research methodology consisting of literature review, case studies and survey questionnaire was designed to achieve the above-mentioned aim. Firstly, literature review was used to examine the concepts of building maintenance, maintainability, the design process and ESI. Secondly, three case studies were presented and analysed to investigate the role of ESI towards enhancing building maintainability during the design process. Thirdly, a survey questionnaire was carried out with a representative sample of architectural design firms (ADFs) in Egypt to investigate their perception and application of ESI towards enhancing building maintainability during the design process. Finally, the research developed a framework to facilitate ESI in the design process in ADFs in Egypt.

Through literature review, the research highlighted the relationship between ESI and enhancing building maintainability and identified the roles, benefits, challenges and that encounter ESI in ADFs, factors for suppliers selection and levels of involvement. Results of the data analysis showed that “Difficulty of trusting external parties and sharing information with transparency” was ranked the highest challenge of ESI in ADFs in Egypt, followed by “Legal competitive advantage restrictions”. Moreover, “Better estimation for operation and maintenance costs” was ranked the highest contributions of ESI towards enhancing building maintainability, followed by “Reduce the number of operation and maintenance problems or reworks”. Finally, respondents stated that “Innovation, technical expertise, and competence” was ranked the highest supplier’s selection criteria, while “paying consultation fees for offering advice and recommendations to the design team” was ranked the highest form of supplier’s remuneration.

The proposed framework contributes to the body of knowledge through proposing five functions that aimed to facilitate ESI in the design process, a research area that received scant attention in construction research. In addition, because of the conceptual nature of the framework, it has to be validated to ensure its capability to overcome the challenges of ESI as an approach for enhancing building maintainability during the design process.

This research presents a practical solution that bridges the gap between theory and practice through overcoming the challenges that obstruct suppliers from being involved in the design process as an approach for enhancing building maintainability.

This research discussed the relationship between ESI and enhancing building maintainability as well as the roles, benefits and challenges that encounter ESI in ADFs. In addition, the research investigated the levels of suppliers’ involvement, selection criteria and forms of payment. Moreover, it investigated the perception and application of ESI in ADFs in Egypt towards improving building maintainability. The research proposed a framework to facilitate the integration of suppliers in the early stages of the project life cycle. It represents a synthesis that is novel and creative in thought and adds value to the knowledge in a manner that has not previously occurred.

This paper investigates the influence of employees’ extra-role and in-role behaviours on customer service alongside the moderating role of gender.

This paper employs the theory of behavioural intentions, cross-sectional survey design and quantitative approach to collect the data from 426 purposively sampled workers and customers of oil marketing companies. The data were analysed using descriptive statistics, correlation and the hierarchical regression model in SPSS.

The results indicate that employees’ extra-role behaviour has a significant positive effect on customer service while employees’ in-role behaviour has no significant effect on customer service. It is also established that gender of staff can significantly moderate the relationship between extra-role behaviour and customer service such that the behaviour of female staff has greater effect on customer service than their male counterparts. However, the gender of staff has no moderating effect on the relationship between in-role behaviour and customer service.

The findings imply that female staff should be allowed to directly engage customers more often than male staff to promote superior customer service. Managers should continuously improve upon the behaviour of employees through orientations, workshops and mentoring. Behaviour stimuli such as awards, appreciations and recognition for best workers would have to be encouraged to induce employees to act beyond their prescribed-roles.

This study is the first to investigate how staff behaviours (in-role and extra-role) impact customer service, with gender of the employees as a moderator. This paper contributes to literature by empirically confirming the differential influence of employees’ extra role and in-role behaviours on customer service and the effectiveness of gender as a moderator on the relationship between extra-role behaviour and customer service from a developing country perspective and an industry where there is dearth of research.

The authors construct an index of economic policy uncertainty (EPU) for Greece using textual analysis and analyze its role in the 10-year Greek economic crisis.

To identify the causal relationship between various measures of economic activity and EPU in Greece, the authors use a sophisticated “shock-based” structural vector autoregressive identification scheme. Additionally, the authors use two additional models to ensure the robustness of the results.

EPU is negatively associated with domestic economic activity and economic sentiment, and positively with bond credit spreads. EPU is also estimated to have prolonged the crisis even in periods when macroeconomic imbalances were cured. The results are robust across various model specifications and different proxies of economic activity.

Brunnermeier (2017) observed that uncertainty may be central to understanding the evolution of the Greek crisis. Yet little attention has been paid to policy uncertainty in the existing long and growing literature on the Greek crisis. The authors attempt to fill this gap.

The purpose of this study was to development of a new chocolate-flavored powdered food supplement enriched with mesquite pod flour, oak extract and agave fructans, with proper sensory characteristics as well as its physicochemical and glycemic quality.

A powdered shake was formulated using experimental design (23) with mesquite (Prosopis laevigata) pod flour, oak (Quercus convallata) extracts, nonalkalinized cocoa, agave fructans, milk protein and xanthan gum. Sensory analysis (choice profile method, ranking test, focus group, quantitative descriptive analysis), moisture, ash, fiber, protein and lipids, pH, color, wettability, dispersibility and rheological tests were done. Phenolic profiling analysis to samples was done by ultraperformance liquid chromatography coupled to photodiode array detection and electrospray ionization tandem mass spectrometry, antioxidant activity was measured by 2,2’-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt radical cation, ferric reducing antioxidant power and oxygen radical absorbance capacity, glycemic index (GI) and glycemic load were evaluated.

The main sensory attributes in the powders were chocolate, bitter, astringent, grass/linseed flavors (p < 0.05). The product has protein [66.9%], carbohydrates [22.0%], lipids [1.6%], ash [2.7%] and moisture [6.8%], with wettability (23 s), and dispersibility of 77.9%. Catechin, epicatechin, gallocatechin, procyanidin B2, chlorogenic, coumaric and ferulic acids were identified. GI and caloric load not show differences between men (73.3±2.4, 4.4±0.1) and women (67.0±2.1, 4.1±0.1) (p > 0.05).

The use of mesquite pods, oak and agave fructans in powder food supplement is an alternative to obtain a product high in protein, with good sensory properties, antioxidant activity and moderate GI.

The purpose of this study include analyzing the conformity between the General Guidelines for the Governance of the Indonesian Sharia Entities (GGG-ISE) and the implementation in the field and proposing a model of corporate governance for Islamic property developers.

This research uses a qualitative method with a case study approach. The researcher used a structured interview method and chose a purposive technique to determine the interviewees. This study has seven interviewees representing three Islamic property developer companies in Jember Regency, East Java, Indonesia. Data collection was conducted from June to July 2023, with a duration of about 60 min for each interviewee. The interviews were conducted face-to-face in each interviewee’s residential office.

The results showed that the companies had implemented several principles of GGG-ISE, namely, ethical and responsible actors, risk management, internal control, compliance, disclosure and transparency by making financial reports, shareholder rights and stakeholder rights, both internal and external stakeholders. Furthermore, this study found that GGG-ISE does not comply with the components of the organizing organ group. This study also found that governance reports have not been implemented in GGG-ISE components. In addition, this study identified a new component that must be present and not found in GGG-ISE, namely, a statement of the use of contracts for mudharib owners and between mudharib owners and stakeholders. Based on these findings, this study proposes a governance model for Islamic property developer companies called the GGG-IPDE.

This research is a pioneer in proposing a corporate governance model for Islamic property developers.

Crack detection of pavement is a critical task in the periodic survey. Efficient, effective and consistent tracking of the road conditions by identifying and locating crack contributes to establishing an appropriate road maintenance and repair strategy from the promptly informed managers but still remaining a significant challenge. This research seeks to propose practical solutions for targeting the automatic crack detection from images with efficient productivity and cost-effectiveness, thereby improving the pavement performance.

This research applies a novel deep learning method named TransUnet for crack detection, which is structured based on Transformer, combined with convolutional neural networks as encoder by leveraging a global self-attention mechanism to better extract features for enhancing automatic identification. Afterward, the detected cracks are used to quantify morphological features from five indicators, such as length, mean width, maximum width, area and ratio. Those analyses can provide valuable information for engineers to assess the pavement condition with efficient productivity.

In the training process, the TransUnet is fed by a crack dataset generated by the data augmentation with a resolution of 224 × 224 pixels. Subsequently, a test set containing 80 new images is used for crack detection task based on the best selected TransUnet with a learning rate of 0.01 and a batch size of 1, achieving an accuracy of 0.8927, a precision of 0.8813, a recall of 0.8904, an F1-measure and dice of 0.8813, and a Mean Intersection over Union of 0.8082, respectively. Comparisons with several state-of-the-art methods indicate that the developed approach in this research outperforms with greater efficiency and higher reliability.

The developed approach combines TransUnet with an integrated quantification algorithm for crack detection and quantification, performing excellently in terms of comparisons and evaluation metrics, which can provide solutions with potentially serving as the basis for an automated, cost-effective pavement condition assessment scheme.
