Abstract

Purpose

Path planning is an important part of UAV mission planning. The main purpose of this paper is to overcome the shortcomings of the standard particle swarm optimization (PSO) such as easy to fall into the local optimum, so that the improved PSO applied to the UAV path planning can enable the UAV to plan a better quality path.

Design/methodology/approach

Firstly, the adaptation function is formulated by comprehensively considering the performance constraints of the flight target as well as the UAV itself. Secondly, the standard PSO is improved, and the improved particle swarm optimization with multi-strategy fusion (MFIPSO) is proposed. The method introduces class sigmoid inertia weight, adaptively adjusts the learning factors and at the same time incorporates K-means clustering ideas and introduces the Cauchy perturbation factor. Finally, MFIPSO is applied to UAV path planning.

Findings

Simulation experiments are conducted in simple and complex scenarios, respectively, and the quality of the path is measured by the fitness value and straight line rate, and the experimental results show that MFIPSO enables the UAV to plan a path with better quality.

Originality/value

Aiming at the standard PSO is prone to problems such as premature convergence, MFIPSO is proposed, which introduces class sigmoid inertia weight and adaptively adjusts the learning factor, balancing the global search ability and local convergence ability of the algorithm. The idea of K-means clustering algorithm is also incorporated to reduce the complexity of the algorithm while maintaining the diversity of particle swarm. In addition, the Cauchy perturbation is used to avoid the algorithm from falling into local optimum. Finally, the adaptability function is formulated by comprehensively considering the performance constraints of the flight target as well as the UAV itself, which improves the accuracy of the evaluation model.

This study aims to evaluate impacts of construction professionals (CPs) conflict on performance in the Nigerian construction industry (NCI).

Abstract

Purpose

This study aims to evaluate impacts of construction professionals (CPs) conflict on performance in the Nigerian construction industry (NCI).

Design/methodology/approach

A quantitative method was used for this research. Questionnaires were sent to various CPs in Southwestern part of Nigeria. A total of 150 questionnaires were sent out, while 135 were gotten back from the partakers. The data received from the partakers were computed by applying descriptive and exploratory factor analysis.

Findings

In this study, conflict leads to the abandonment of the CPs’ task being rated highest by the participants. This was followed by conflict that results in insufficient communication, generates job pressure, results to frustrations and displeasure among the CPs, helps in early problem identification, causes work damage among professionals, helps in solving professional organization problems, improves productivity of professionals, improves communication among the professionals and so on.

Research limitations/implications

This paper is limited to CPs that are members of professional bodies in Nigeria, and only 135 participants participated. Though, this paper suggests that a mixed-method approach should be utilized in further studies with a wider coverage.

Practical implications

The findings from this paper will increase the understanding of CPs in Nigeria on various impacts of conflict on performance in the construction industry, most specifically the professional bodies. Moreover, this study will increase the knowledge of CPs to always avoid whatever that leads to the abandonment of their tasks. Additionally, this study will benefit the CPs to avoid insufficient communication among themselves, in order to accomplish great performance and efficiency in their respective professional bodies.

Originality/value

Since previous studies on impacts of construction conflict in Nigeria were only focused on contractors and consultants in construction project, this current study filled the gap by evaluating the impacts of CPs’ conflict on performance in the NCI. Also, the method of analysis used for this study is exemptional because previous studies have overlooked the method. However, it is recommended that CPs must communicate more with others so as to ensure favorable conflict effects on performance.

Abstract

Purpose

The paper aims to assess the impact and responses to coronavirus disease 2019 in six European heritage labs (Horizon 2020 Framework Programme) selected for their adaptive heritage re-use practices based on participation, self-organisation and self-management. As they are naturally oriented towards building resilient urban systems, the hypothesis is that the co-production of cultural values and places promoted by these projects could create the conditions for equitable perspectives of resilience in the normality of contemporary urban life.

Design/methodology/approach

The paper draws on data collected through a survey of six European Living Labs between January and May 2021. The survey results are framed by a literature review that defines adaptive reuse in terms of resilience. The five resilience characteristics described by Judith Rodin (awareness, diversification, integration, self-regulation and adaptability) are used to navigate the literature and organise the survey results.

Findings

Combining survey results and insights from the literature, some modes and elements (territorial, social, financial) are presented that contribute to creating the conditions for resilience through adaptive heritage reuse according to community-based approaches. Without claiming to be exhaustive, this evidence should be considered in the design phase of resilience programmes, policies or projects related to cultural heritage.

Originality/value

The concepts of community and resilience are becoming increasingly important in the field of cultural heritage. This paper makes a creative contribution to the ongoing debate by presenting and evaluating the contribution of adaptive reuse practices to resilience building.

Abstract

Purpose

The retail sector has the largest energy consumption among commercial buildings in the U.S. Although previous studies explored benefits, barriers and solutions for implementing sustainability in various building sectors, research focused on retail facilities has been very scarce. This study aims to explore U.S. facilities managers’ perceptions of barriers that prevented the implementation of energy-efficiency practices in the retail sector. Their perceptions were compared by facility size and facilities management company’s business revenue.

Design/methodology/approach

An online survey was distributed to the members of the International Facility Management Association and the author's LinkedIn network. The survey responses were analyzed using descriptive statistical analysis and ANOVA.

Findings

Managers from large facilities, as opposed to those from small ones, significantly more agreed that the unavailability of building automation systems, a lack of professional writing skills and a lack of awareness of life cycle cost (LCC) were the barriers. Business revenue did not cause significantly different perceptions of the barriers except for a lack of awareness of LCC and a lack of support from upper management.

Originality/value

This study fills the research gap on energy efficiency in the retail sector by revealing U.S. facilities managers’ perceptions of the barriers to the implementation of energy-efficiency practices in retail stores. This novel study compares perceptions of the facilities managers by facility size and business revenue; this comparison has not been performed before. The study also identified several new barriers to the implementation of energy efficiency in the retail sector.

The study aims to have adults discuss experiences, practices needs and feelings related to health management, diet and food security.

Abstract

Purpose

The study aims to have adults discuss experiences, practices needs and feelings related to health management, diet and food security.

Design/methodology/approach

A total of 22 immigrants were recruited from the Open School of Immigrants in Piraeus, Attica, Greece, to participate in focus group discussions. The discussions were audio recorded and thematically analyzed. Three major themes were developed: pathways to health care, nutrition management and experiences related to food shortages.

Findings

Most of the participants identified internet as the most commonly used way to obtain health advice; they also stated that unexpected ill-health is usually accompanied by feelings of fear, anxiety and loneliness. Immigrants, who had visited a public hospital in Greece, identified the language barrier as the most challenging issue, followed by the long waiting lists. Fear and anxiety of hospital visits was an important factor in their decision to vaccinate against COVID-19. Lack of time, high cost of healthy food and lack of knowledge were the most common obstacles to a healthy diet. One in two immigrants reported that they have faced food insecurity issues in the past. Stress, psychological distress and irritation were reported, due to food shortages, especially during the first few years of arriving in Greece. The exclusion of some foods, reduced portion sizes and buying cheaper foods were among the coping strategies to address food shortages.

Originality/value

The study offers an insight into immigrant’s experiences, practices and feelings about managing health issues and could be useful for health-care practitioners, researchers and policymakers.

Abstract

Purpose

This study aims to recognize the significant barriers of small and medium-sized enterprises (SMEs) in Bangladesh, hindering the adoption of total quality management (TQM). Additionally, this research intends to explore the interrelations among these barriers to develop essential managerial insights for promoting TQM implementation in SMEs.

Design/methodology/approach

The interpretive structural modeling (ISM) approach and Matrice d'impacts croisés multiplication appliquée á un classment (MICMAC) a cross-impact matrix multiplication applied to classification show the relationship among the barriers and classification of the barriers to TQM implementation respectively, and partial least squares structural equation modeling (PLS-SEM) is applied for ISM model validation.

Findings

This study examined previous literature and conducted interviews with professionals to identify 17 barriers. The study then develops and investigates a model that outlines the relationships and priorities among these barriers and categorizes them based on their impact and interdependence. This analysis can assist SMEs in implementing TQM during their operations successfully.

Practical implications

This research emphasizes the crucial obstacles that greatly affect other barriers and require immediate attention. Furthermore, this study provides valuable information for SMEs to effectively prioritize their resources and efforts to overcome these obstacles.

Originality/value

This study delves into the primary obstacles impeding the integration of TQM in SMEs through a novel approach. Additionally, this study constructs a verified contextual framework that depicts the hierarchies and interconnections among these barriers.

Abstract

Purpose

This study aims to examine Braille usage among consumers with visual impairments, investigating motivations and addressing inherent challenges.

Design/methodology/approach

Drawing insights from 16 semistructured interviews with individuals experiencing blindness, this study reveals nuanced aspects of Braille utilization.

Findings

Three key motivations for Braille usage are identified: as a coping mechanism for functional needs and to combat stigma; as an embodied experience contributing to pleasure; and as a heritage embodying a culture of visual impairment. Obstacles include cultural and financial barriers to learning, incomplete retail transcriptions limiting practicality and spatial congestion issues.

Originality/value

This study underscores Braille’s dual function as both coping mechanism and cultural heritage. By highlighting obstacles, it sheds light on challenges faced by consumers with visual impairments, facilitating advocacy and promoting inclusive retail practices. Originality lies in recognizing diverse motivations and experiences among Braille users, offering insights for enhancing tactile engagement in the marketplace.

Abstract

Purpose

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).

Design/methodology/approach

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.

Findings

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.

Practical implications

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.

Originality/value

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.

Abstract

Purpose

This study aims to explore possible behavioural change venues, beyond the traditional approach to financial education, using the capability-opportunity-motivation behaviour theoretical framework of behavioural change.

Design/methodology/approach

The study included 45, semi-structured, in-depth interviews of young adults to explore which elements of financial behaviour formation should interventions target to be effective.

Findings

To strengthen capability, the study recommends behavioural education and training for boosting financial knowledge and skills, enablement of financial independence and modelling for empowering self-control and reducing impulsiveness. To boost motivation, gamification of modelling is advised for boosting responsible financial behaviour as part of the identity and inducing consideration of future consequences. Persuasion is advised for inducing positive emotions while incentivization and coercion are advised for empowering self-conscious intentions. To rise opportunity, the study proposes incentivization and coercion imposed by parents, and governmental efforts regarding restriction, enablement and environmental restructuring.

Practical implications

The study brings recommendations for developing efficient interventions for strengthening responsible financial behaviour that may help design type-specific education programmes to promote responsible financial behaviour.

Originality/value

The present study attempts to explore new venues in intervention design that break away from the traditional approach of financial education focused on knowledge and skills that is proven to be ineffective
