Abstract
Purpose
This study aims to explore the impact of retail facilities’ (RF) characteristics on customers' spatial cognition and accessibility to products, which inherently affect the facility's performance. Namely, the ratios of the facilities’ dimensions and the shelving configurations are investigated.
Design/methodology/approach
The visual attributes of RF are used as the method of assessment, relying on the principles of the Space Syntax theories; several design alternatives of RF are generated which represent different characteristics and compared using computer software (Depthmap X). The perceived variance in performance sheds light on the influence of the investigated characteristics.
Findings
The results have pointed out that dimension ratios can affect the facilities’ performance, especially with the shelving configuration considered. Furthermore, certain shelving layouts are more advantageous compared to other layouts. Other design features have been concluded, shedding light on measures for optimizing performance.
Research limitations/implications
Due to the endless number of possibilities of retail facility designs, the study has focused on simplified designs only, excluding intricate designs which can possibly offer an additional important perspective on design influences.
Practical implications
The findings benefit the RF sector by producing customer-centered designs through optimizing layouts and configurations, improving product visibility and enhancing accessibility. This potentially enhances costumers' experiences and promotes satisfaction, thus attracting more consumers and increasing sales.
Originality/value
Although the Space Syntax principles are long-established, their application to RF is novel. This is also true for the findings which can represent a guide for retail facility designs.

Abstract
Purpose
The global market for cloud gaming is growing rapidly. How gamers evaluate the service quality of this emerging form of cloud service has become a critical issue for both researchers and practitioners. Building on the literature on service quality and software as a service, this study develops and validates a gamer-centric measurement instrument for cloud gaming service quality.
Design/methodology/approach
A three-step measurement instrument development process, including item generation, scale development and instrument testing, was adopted to conceptualize and operationalize cloud gaming service quality.
Findings
Cloud gaming service quality consists of two second-order constructs of support service quality and technical service quality with seven first-order dimensions, namely rapport, responsiveness, reliability, compatibility, ubiquity, smoothness and comprehensiveness. The instrument exhibits desirable psychometric properties.
Practical implications
Practitioners can use this new measurement instrument to evaluate gamers' perceptions toward their service and to identify areas for improvement.
Originality/value
This study contributes to the service quality literature by utilizing qualitative and quantitative approaches to develop and validate a new measurement instrument of service quality in the context of cloud gaming and by identifying new dimensions (compatibility, ubiquity, smoothness and comprehensiveness) specific to it.

Abstract
Purpose
This study aims to propose a framework to assess the scientific productivity performance of a country in terms of its international visibility and national capabilities.
Design/methodology/approach
In a given subject, all publications with at least one author from the target country as well as the received citations are counted as quantitative and qualitative indicators, respectively. The ratios of these counts to their expected values, which are estimated according to the global gross domestic product (GDP) and population percentages of the country are used to assess international visibility. Also, in certain publications, all authors are from the target country, therefore, their publication and citation proportions are provided as metrics of national competence.
Findings
As a sample, this study analyzes Turkey’s performance in “Business, Economics & Management” and “Engineering & Computer Science” in the top 20 publication venues of the regarding subject areas according to Google Scholar Metrics taxonomy. This study shows that in some subfields, Turkey’s performance is 2.73–6 times as per expectations. This study also provides the international visibility assessment of all countries for the past two decades in “Theoretical Computer Science” which shows that Israel is a leading country based on this framework.
Originality/value
This paper introduces new indices to evaluate a country’s national competence and international visibility on a subject field based on the number of published papers affiliated with the country and their citations by considering the global GDP and population share.

Abstract
Purpose
This paper aims to identify the kind of internal climate leaders should offer health-care professionals to promote a patient safety culture in public hospitals managed by social health organizations in Brazil.
Design/methodology/approach
Two surveys were applied to health-care professionals working at three Brazilian public hospitals. The internal climate survey reached 1,013 respondents, and the patient safety culture survey reached 1,302 participants. Both factor and regression analyses were used to analyze the study model and determine how internal climate influences patient safety culture.
Findings
Results indicate that to promote a patient safety culture among health-care professionals, leaders should generate an internal climate based on trust to foster pride in working in the hospital. Possibly, the trust dimension is the most important one and must be developed to achieve job satisfaction and provide better services to patients.
Research limitations/implications
All the hospitals studied were managed by the same Organização Social de Saúde. Due to the limited responses concerning the respondents’ profiles, demographic variables were not analyzed.
Practical implications
This research reveals that the trust and pride dimensions can most strongly influence a positive patient safety culture, helping hospital leaders face this huge managerial challenge of consistently delivering high standards of patient safety.
Originality/value
This research studies the promotion of a patient safety culture in public hospitals managed by social health organizations, characterized by greater flexibility and autonomy in health-care management and by a greater need for accountability.

Abstract
Purpose
Although some architects have found spatial order and proportion strategy effective in designing the environment for autistic children, it is not clear what spatial ratios are preferred for autistic people. Therefore, this study aims to find the desired ratio among autistic and non-autistic children.
Design/methodology/approach
The scale model questionnaire was chosen to determine the difference in the ratio preferences for autistic and non-autistic children, whereas two access types between the space zones are also considered. The questionnaire was administered to 50 autistic children, with a half-and-half distribution of moderate and mild autism groups, while males are twofold. It was also administered to 50 non-autistic children, approximately equal in terms of gender division. The scale model was designed in the form of a dollhouse to be played with a doll in 6 varied rooms categorized by 3 different ratios (1:1, golden ratio, 1.6:1 and 5:2) and 2 access types (linear and radial access) to measure how many times each room was selected by each group to run numerical analysis.
Findings
It was shown that, although the golden ratio has been previously considered in space design for autistic children, they appealed to the ratio of 2:5 with high frequency. While there is a significant difference between the spatial ratios preferred by autistic and non-autistic children choosing the golden ratio, the same type of space access system is preferred by both groups in their results.
Originality/value
Despite the prevalent use of the golden ratio in design for autism design, this research shaped an empirical study for autistic users concluding a different perspective in design for autism.

Abstract
Purpose
This paper aims to clarify the resistance degree of group road logistics to flood disaster resilience. The paper measures the resilience of group road logistics by establishing network structure model. The purpose of this study is to improve the resilience of road log.
Design/methodology/approach
This paper adopts Delphi method to collect data, interviews mainly flood management experts and supply chain risk management experts, and then analyzes the data through the network structure model combined with interpretative structure model (ISM) and analytical network process (ANP).
Findings
The results show that flood frequency and drainage systems are the main factors affecting the resilience of road transport logistics in urban areas. These research results provide useful guidance for the effective planning and design of urban road construction and infrastructure.
Research limitations/implications
However, the main factors affecting the resilience of road transport logistics are likely to change with the development of factors such as climate, economy and environment. Therefore, in future work, the authors' research will focus on the further application of this evaluation method.
Practical implications
The results show that the impact of flooding on the four dimensions of road logistics resilience varies. This shows that in deciding what intervention measures are to be taken to improve the resilience of the road network to flooding, various measures need to be considered.
Social implications
This paper provides a more scientific analysis of the risk management ability of the road network in the face of floods. In addition, it also provides a useful reference for urban road planners.
Originality/value
This paper addresses a clear need to study how to build models to improve the resilience of road logistics in flood risk.

Abstract
Purpose
The purpose of this paper is to investigate the free vibration response of a laminated honeycomb sandwich panels (LHSP) for aerospace applications. Higher order shear deformation theory (HSDT) was simplified for the dynamic analysis of LHSP. Furthermore, the effects of honeycomb parameters on the value of natural frequency (NF) of vibration were explored.
Design/methodology/approach
This paper applies HSDT to the analysis of composite LHSP to derive four vibration differential equations of motion and solve it to find the NF of vibration. Two analytical models (Nayak and Meunier models) were selected from literature for comparison of the NF of vibration. In addition, a numerical model was built by using ABAQUS and the results were compared. Furthermore, parametric studies were conducted to explore the effect of honeycomb parameters on the value of the NF of vibration.
Findings
The present model is successful in simplifying HSDT for the analysis of LHSP. The first five natural frequencies of vibration were calculated analytically and numerically. In the parametric study, increasing core height or young’s modulus or changing laminate layup will increase the value of NF of vibration. Furthermore, increasing plate constraint (using clamped edge boundary condition) will increase the value of NF of vibrations.
Research limitations/implications
The current analysis is suitable for all-composite symmetric LHSP. However, for isotropic or non-symmetric materials, minor modifications might be adopted.
Originality/value
The application of simplified HSDT to the analysis of LHSP is one of the important values of this research. The other is the successful and complete dynamic analysis of all-composite LHSP.

This paper aims to investigate the impact of board characteristics on environmental, social and governance (ESG) disclosure in the energy industry of emerging economies.
Abstract
Purpose
This paper aims to investigate the impact of board characteristics on environmental, social and governance (ESG) disclosure in the energy industry of emerging economies.
Design/methodology/approach
The authors adopt the Bloomberg ESG rating to measure the extent of ESG disclosure using a sample of 1,260 observations from BRICS emerging economies. Multiple regression techniques were used to estimate the effect of board characteristics on ESG disclosures of a sample Brazil, Russia, India, China, and South Africa (BRICS) listed companies between 2010 and 2019.
Findings
The authors find a relatively low (at 37%) level of ESG disclosure among the sampled firms and a relatively high degree of variability. The authors also find that board gender diversity, board composition and board diligence are positively related to the level of ESG disclosure while the study documents no relationship between board size and ESG disclosure.
Practical implications
The study’s findings highlight the importance of corporate board attributes in influencing strategic decisions such as the level of ESG disclosure and the findings may be useful to regulators, policymakers and investors in making informed investment decisions.
Originality/value
To the best of the authors’ knowledge, this study is one of the first attempts at examining the impact of board characteristics on ESG disclosure in the energy industry in emerging economies. The paper provides new evidence on the relationship between board characteristics (BC) and ESG disclosure in the energy industry of emerging BRICS countries within a panel multi-country research setting.
