Abstract

Purpose

Contractor selection is critical in green buildings (GBs) since the preferred contractor has the responsibility to achieve construction sustainability as well as relationship sustainability. The developer satisfaction reflecting requirements can boost the cooperative relationship among stakeholders and act as an evaluation scale for the success of GB projects, which needs to be emphasized in the selection process but little involved in the existing research. This study explores improving GB contractor (GBC) selection by integrating developer satisfaction into selection procedures.

Design/methodology/approach

A systematic framework of GBC selection including twenty-five criteria from literature review and experts survey is firstly constructed. Both tactical and strategic criteria are further classified into Kano categories (must-be, one-dimensional, and attractive categories) using the fuzzy Kano model (FKM), and weighted by the developer satisfaction index. The model proposed by this study combining FKM and TOPSIS divides the selection process into the filtration phase and selection phase by Kano categories. The proposed model is finally verified through performance comparison among multiple methods in a case.

Findings

Selection criteria are measured linearly and nonlinearly, showing criteria having nonlinear satisfaction change accounts for two-thirds of all. Criteria at tactical level tend to be must-be or one-dimensional categories for the developer, and most strategic criteria are classed as the attractive category, indicating that adding strategic criteria is necessary for long-term cooperation. The proposed model, using developer satisfaction to improve the selection process, ensures the selected GBC to be the most satisfactory with requirements of the developer and makes the performance of GBCs easily distinguishable.

Originality/value

This study contributes to the existing body of knowledge for promoting relationship sustainability by supplementing an integrated model with emphasis on developer satisfaction in GBC selection, so as to establish a good initial foundation due to the match between performances of GBCs and needs of developers. It not only helps maximize developer satisfaction in GBC selection by applying satisfaction to pre-construction management, but also instructs GBCs to prioritize performance improvements. The framework is also conducive for developers to classify selection criteria and select other participants (like green suppliers) from the satisfaction perspective in GBs.

Abstract

Purpose

Construction material management plays a significant role in achieving successful project delivery of a construction project. However, ineffective material management is a critical issue in the construction industry, especially in developing economies, of which Sri Lanka is not an exception. Therefore, this study aims to focus on exploring the causes of ineffective material management practices in civil engineering construction projects in Sri Lanka and their impact on successful project delivery.

Design/methodology/approach

Furthermore, the literature findings were validated through the preliminary survey. Subsequently, a quantitative research approach was adopted to pursue the research aim. Questionnaire responses were obtained from 215 construction professionals in civil engineering projects who were selected using the judgemental and snowball sampling techniques. Collected data were analysed through Statistical Package for the Social Sciences (SPSS) V26 and Microsoft Excel 2016.

Findings

Moreover, the study revealed that material price fluctuation, shortage of material in the market, delay in material procurement, inadequate planning and delays in material delivery are the most frequent causes of ineffective material management in civil engineering projects. In addition, it was evidenced that most ineffective material management practices cause both time and cost overruns in civil engineering construction projects. Most respondents emphasized inadequate planning, inadequate qualified and experienced staff, lack of supervision and lack of leadership as the causes for both time and cost overruns.

Originality/value

The study was concluded by proposing strategies for effective material management. Education/training/enlightenment of staff in charge of materials management, use of software like Microsoft Project, Primavera and similar software to eliminate manual errors in material management, and providing clear specifications to suppliers were the most agreed strategies for effective material management in civil engineering construction projects.

Abstract

Purpose

Images taken from construction site interiors often suffer from low illumination and poor natural colors, which restrict their application for high-level site management purposes. The state-of-the-art low-light image enhancement method provides promising image enhancement results. However, they generally require a longer execution time to complete the enhancement. This study aims to develop a refined image enhancement approach to improve execution efficiency and performance accuracy.

Design/methodology/approach

To develop the refined illumination enhancement algorithm named enhanced illumination quality (EIQ), a quadratic expression was first added to the initial illumination map. Subsequently, an adjusted weight matrix was added to improve the smoothness of the illumination map. A coordinated descent optimization algorithm was then applied to minimize the processing time. Gamma correction was also applied to further enhance the illumination map. Finally, a frame comparing and averaging method was used to identify interior site progress.

Findings

The proposed refined approach took around 4.36–4.52 s to achieve the expected results while outperforming the current low-light image enhancement method. EIQ demonstrated a lower lightness-order error and provided higher object resolution in enhanced images. EIQ also has a higher structural similarity index and peak-signal-to-noise ratio, which indicated better image reconstruction performance.

Originality/value

The proposed approach provides an alternative to shorten the execution time, improve equalization of the illumination map and provide a better image reconstruction. The approach could be applied to low-light video enhancement tasks and other dark or poor jobsite images for object detection processes.

Abstract

Purpose

This investigation serves a dual purpose: providing preliminary results and serving as a pilot study to confirm the viability of the hypotheses advanced towards a full-scale study. This paper aims to present the preliminary findings of an investigation that explored the constructs of personality traits and situational crime prevention theory (SCPT) as antecedents to social cognitive determinants (attitude, perceived behavioural control and subjective norms using the theory of planned behaviour [TPB] framing) and how these elements subsequently estimate compliant information security behaviour. Moreover, this paper delves into the contrasting influences of light and dark personality traits on insider information security compliance.

Design/methodology/approach

A cross-sectional survey was conducted to study SCPT measures and the personality factors dyad using a diverse but limited sample (n = 82).

Findings

There were ten significant direct relationships between SCPT factors and personality traits related to the components of the TPB. Seventeen hypotheses were not supported. However, these findings highlight the complexity of the topic under study.

Practical implications

Understanding individual differences within the compliance model could be used for custom training protocols, employee selection, assignment and specific types of information security interventions.

Originality/value

There is a scarcity of studies considering the effects of situational and personality factors, specifically the dark versus light triad of personality traits within the information security domain. Therefore, this preliminary result provides early insight that could guide further studies. This research could have important implications for organisations at risk of insider attacks.

Abstract

Purpose

Seasonal influenza epidemics accounted for significant morbidity and mortality loads worldwide despite the availability of a safe vaccine as an efficient tool against severity of the disease. However, the uptake of the latter was sub-optimal. This study aims to identify predictors and barriers related to seasonal influenza vaccine uptake in the Kingdom of Bahrain.

Design/methodology/approach

A cross-sectional study enrolled 502 individuals attending primary healthcare centers in Bahrain for ambulatory care between July and August 2022. The data were collected using an interviews-based questionnaire which included questions on demographic data, knowledge and attitudes and practices toward influenza vaccine. The authors identified the barriers as well as the determinants of the vaccine uptake and its recommendation to others.

Findings

The mean age of participants was 35.07 years (SD = 13.9). Most of the respondents were Bahraini (86.5%) and 53.4 % were females. The results revealed that 34.1% have previous information about the influenza vaccine and 36.9% versus 69.9% are willing to receive the vaccine or advice it to others, respectively. Determinants of vaccine uptake were identified.

Originality/value

This study confirmed a sub-optimal influenza vaccine acceptance in the general community of Bahrain despite a global access in primary care. Health professionals need to be more proactive in mobilizing the community and particularly females toward influenza vaccination.

Abstract

Purpose

The study investigates the antecedents and consequences of digital ad avoidance in the e-commerce industry. This study aims to investigate how digital ad avoidance relates to internet usage over time, using a two-wave longitudinal research design. This study also explores how real-world advertising clutter (clutter and non-clutter) affects these relationships.

Design/methodology/approach

The data were collected from 192 online consumers in Türkiye, and a two-wave longitudinal research design and structural equation modeling were conducted to test the hypotheses of the conceptual model.

Findings

The results indicated that perceived goal impediment and prior negative experience had positive effects on affective avoidance in both ad-clutter and non-clutter periods. Further, affective avoidance had a significant positive effect on both cognitive and behavioral avoidance in either period. In addition, ad clutter moderated the effects of cognitive and behavioral avoidance on online purchase intention.

Originality/value

This research provides new evidence of the crucial role perceived goal impediment, prior negative experience and perceived control each play in driving digital ad avoidance. This paper contributes to the body of knowledge in the field by exploring how advertising clutter (both cluttered and non-cluttered settings) moderates these relationships through a two-wave longitudinal study.

Abstract

Purpose

We explore how NGO’s local entrepreneurial initiatives to empower women entrepreneurs can compensate for weak state policies for women in a context of male-dominated socio-cultural norms.

Design/methodology/approach

We use the case of a local entrepreneurial initiative launched in the Atlas region of Morocco, the Empowering Women in the Atlas Initiative (EWA). We collected data through 51 semi-structured interviews of women entrepreneurs in three cooperatives which exploit the natural resources of their region to establish a social venture. Our data are longitudinal as they were collected at two time periods: before and after the initiative.

Findings

The findings of this study suggest that local entrepreneurial initiatives can have a significant impact on rural women entrepreneurs’ empowerment. The improved perception of empowerment has not only helped them develop capacities to leverage the business opportunities linked to the natural resources of their region, but it has also increased their status and role within their family and community.

Practical implications

We make recommendations for policymakers to encourage this type of initiative to compensate for the absence of supporting policies geared toward women.

Originality/value

Our study is one of the first to look at empowerment as a policy instrument to develop women entrepreneurial activities in rural areas of developing countries. Our paper uses a unique hierarchical perspective and a multidimensional framework for analyzing social cooperative ventures and rural women entrepreneurs’ empowerment. Our paper unravels interesting insights for women entrepreneurs’ narration strategies.

Abstract

Purpose

This research purpose was to explore the meaning of historicism, architectural historicism, the architectural attributes, design principles, elements and ornamentations of churches in medieval Western architecture, and how they were reflected in contemporary churches' design in Jordan.

Design/methodology/approach

This research used the historical descriptive–interpretive qualitative research method. Around 24 Western medieval churches were selected, studied and analyzed to explore the common design attributes of each historical era. The design attributes of each era were segmented under three categories: Design principles (plans' typology, facades, shapes, details, composition and building form), design elements (openings, towers and entrances) and ornamentation (sculptures, paintings and interior decoration). Additionally, three modern Jordanian churches were analyzed using the same method to compare with the historical churches through personal observations, field trips, researchers' memories, site visits, archival records, plans, images, books, slides, details and note-making. Different types of evidence were used, such as determinate, contextual and inferential. In addition, different tactics for analysis were used in analyzing the historical churches: site familiarity, use of existing documents, virtual and visual inspection and comparison with conditions elsewhere. Credibility was achieved when the results were reviewed and compared with the original and similar information.

Findings

Early Christian design principles, elements and ornamentations were reflected in Jordanian churches more than in Byzantine, Renaissance, Romanesque and Gothic. The design principles of Western medieval architecture were reflected in the selected Jordanian churches more than in ornamentation and design elements. Moreover, this research found that the highest reflection of Western medieval architecture on Jordanian churches was in designing the plans, which is a basilica with a central nave and aisles followed by opening styles, façade, shapes, entrances design, composition, painting and the minimum reflection was in sculptures. Additionally, there was no reflection on tower design and interior decoration.

Practical implications

This research encourages architects to enhance architectural historicism by focusing on historical styles in contemporary designs and using design elements, principles and decorations of historical styles in medieval architecture to enrich the variety and originality of architectural design and create new modern stylistic architecture. Architectural historicism increases historical self-awareness and helps a generation of architects to answer the question: In what style should be built.

Originality/value

Learning the design principles, not copying the past, is becoming a trend for most architects. Architectural historicism introduces new temporal elements, gives a new meaning and primary function to architecture to become socio-temporal and contextual contrast and reflects the essential points of references of the past through design methodology to express the present. The advantage of this research is to put an end to architects' role in syncretism and subjectivism. Instead, historicism architects equipped with the necessary knowledge and supported by the published research and inventors of historical architecture, can choose, imitate, adapt, borrow and use the correct historical forms that originated in a given period.

Abstract

Purpose

Despite ongoing reports of insider-driven leakage of confidential data, both academic scholars and practitioners tend to focus on external threats and favour information technology (IT)-centric solutions to secure and strengthen their information security ecosystem. Unfortunately, they pay little attention to human resource management (HRM) solutions. This paper aims to address this gap and proposes an actionable human resource (HR)-centric and artificial intelligence (AI)-driven framework.

Design/methodology/approach

The paper highlights the dangers posed by insider threats and presents key findings from a Leximancer-based analysis of a rapid literature review on the role, nature and contribution of HRM for information security, especially in addressing insider threats. The study also discusses the limitations of these solutions and proposes an HR-in-the-loop model, driven by AI and machine learning to mitigate these limitations.

Findings

The paper argues that AI promises to offer many HRM-centric opportunities to fortify the information security architecture if used strategically and intelligently. The HR-in-the-loop model can ensure that the human factors are considered when designing information security solutions. By combining AI and machine learning with human expertise, this model can provide an effective and comprehensive approach to addressing insider threats.

Originality/value

The paper fills the research gap on the critical role of HR in securing and strengthening information security. It makes further contribution in identifying the limitations of HRM solutions in info security and how AI and machine learning can be leveraged to address these limitations to some extent.

Abstract

Purpose

This study aims to examine the influence of perceived supervisor support (PSS) for strengths use on knowledge sharing (KS) intentions, mediated through work engagement and knowledge self-efficacy, based on the job demand-resources theory and the broaden and build theory.

Design/methodology/approach

Structural equation modeling and bootstrap analyses were performed to examine the research model using data derived from a two-wave questionnaire survey of 162 employees from five health-care organizations.

Findings

The results indicate that PSS for strengths use promoted KS intentions fully mediated through work engagement and subsequently through knowledge self-efficacy. However, there was no direct relationship between PSS for strengths use and KS intention.

Originality/value

The contribution of this research to the literature on KS is to find the effectiveness of a strengths-based approach in promoting KS intentions across boundaries and identifying mediating factors that link PSS for strengths use to KS intentions.
