Abstract
Purpose
This study was conducted to address the methodical shortcomings and high associated cost of understanding the use of new, poorly understood architectural spaces, such as makerspaces. The proposed quantified method of enhancing current post-occupancy evaluation (POE) practices aims to provide architects, engineers and building professionals with accessible and intuitive data that can be used to conduct comparative studies of spatial changes, understand changes over time (such as those resulting from COVID-19) and verify design intentions after construction through a quantified post-occupancy evaluation.
Design/methodology/approach
In this study, we demonstrate the use of ultra-wideband (UWB) technology to gather, analyze and visualize quantified data showing interactions between people, spaces and objects. The experiment was conducted in a makerspace over a four-day hackathon event with a team of four actively tracked participants.
Findings
The study shows that by moving beyond simply counting people in a space, a more nuanced pattern of interactions can be discovered, documented and analyzed. The ability to automatically visualize findings intuitively in 3D aids architects and visual thinkers to easily grasp the essence of interactions with minimal effort.
Originality/value
By providing a method for better understanding the spatial and temporal interactions between people, objects and spaces, our approach provides valuable feedback in POE. Specifically, our approach aids practitioners in comparing spaces, verifying design intent and speeding up knowledge building when developing new architectural spaces, such as makerspaces.

Abstract
Purpose
This article takes into account object identification, enhanced visual feature optimization, cost effectiveness and speed selection in response to terrain conditions. Neither supervised machine learning nor manual engineering are used in this work. Instead, the OTV educates itself without instruction from humans or labeling. Beyond its link to stopping distance and lateral mobility, choosing the right speed is crucial. One of the biggest problems with autonomous operations is accurate perception. Obstacle avoidance is typically the focus of perceptive technology. The vehicle's shock is nonetheless controlled by the terrain's roughness at high speeds. The precision needed to recognize difficult terrain is far higher than the accuracy needed to avoid obstacles.
Design/methodology/approach
Robots that can drive unattended in an unfamiliar environment should be used for the Orbital Transfer Vehicle (OTV) for the clearance of space debris. In recent years, OTV research has attracted more attention and revealed several insights for robot systems in various applications. Improvements to advanced assistance systems like lane departure warning and intelligent speed adaptation systems are eagerly sought after by the industry, particularly space enterprises. OTV serves as a research basis for advancements in machine learning, computer vision, sensor data fusion, path planning, decision making and intelligent autonomous behavior from a computer science perspective. In the framework of autonomous OTV, this study offers a few perceptual technologies for autonomous driving in this study.
Findings
One of the most important steps in the functioning of autonomous OTVs and aid systems is the recognition of barriers, such as other satellites. Using sensors to perceive its surroundings, an autonomous car decides how to operate on its own. Driver-assistance systems like adaptive cruise control and stop-and-go must be able to distinguish between stationary and moving objects surrounding the OTV.

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
Although photographs in sustainability reports are useful in conveying complex messages, they may also be used to manipulate the presentation of disclosures to exploit the limited cognitive processing capacity of humans. Therefore, this paper aims to examine the features of photographs aimed at capturing individuals’ attention through visual structures and evoking specific emotions through carefully chosen content. Furthermore, it examines whether such framing practice is explained by incentives for legitimizing behaviours and influencing reputation.
Design/methodology/approach
The authors conduct a content analysis of photographs in 154 sustainability reports published by US companies. The authors captured the nature of photographs, the context in which they are being used, their themes and emotional content and layout and interaction features to understand how photographs are used for attribute framing to influence information processing. Furthermore, the authors statistically examine the framing practice between companies with different characteristics to identify any patterns for the impression management use of photographs in sustainability reports.
Findings
Photographs are often large with a horizontal orientation to capture attention and show content viewed at eye level and in either medium or close-up shots to engage viewers. Furthermore, photographs are emotionally loaded with different themes such as depictions of people, technology and nature. These themes are used to predominately evoke positive emotions of awe, nurturance, pride, amusement and attachment. This practice is often used by companies in environmentally sensitive areas that have close consumer relationships or are covered controversially in the media.
Originality/value
The authors reveal reporting practices and identify photographic features that attract attention and convey emotions that go beyond aesthetic qualities. This is important because emotions conveyed through photographs can be potentially misleading and influence judgements subconsciously.

Abstract
Purpose
This study aims to enhance the understanding of the current research landscape regarding the utilisation of telepresence robots (TPRs) in education.
Design/methodology/approach
The bibliometric and thematic analysis of research publications on TPRs was conducted using papers in the Scopus database up to 2023. The final analysis focused on 53 papers that adhered to the selection criteria. A qualitative analysis was performed on this set of papers.
Findings
The analysis found a rising trend in TPR publications, mostly from the USA as conference papers and journal articles. However, these publications lacked technology integration frameworks, acceptance models and specific learning design models. TPRs have proven effective in various learning environments, fostering accessible education, better communication, engagement and social presence. TPRs can bridge geographical gaps, facilitate knowledge sharing and promote collaboration. Obstacles to implementation include technical, physical, social and emotional challenges. Publications were grouped into four thematic categories: didactic methods of using TPRs, TPRs for educational inclusivity, TPR as a teacher mediator and challenges in using TPRs. Despite the significant potential of TPRs, their broader adoption in education is still facing challenges.
Research limitations/implications
This research solely analysed research papers in the Scopus database, limiting TPR publications with the keywords “telepresence robots”, “learning”, “teaching” and “education”, excluding studies with different other keywords.
Originality/value
This study enhances understanding of TPR research in education, highlighting its pedagogical implications. It identifies a gap in the inclusion of technology integration frameworks, acceptance models and learning design models, indicating a need for further research and development.

Purpose
The main purpose of the study to identify the importance of computer devices in vocational studies for person with disabilities (PwDs) are as follows: This study aims to observe the role of computer training in vocational training of a PwD. This study plays an important role in the vocational training of a PwD. With the help of ICT curriculum, effective vocational training is possible to help the trainee, the parents, the professional, the employer and the community easily. It builds awareness about career and employment options for individuals with disabilities.
Design/methodology/approach
The present investigation is descriptive research. The study has divided in to two phases such as—in the first phase of the study, the researcher has developed the tool for demographic data of PwDs. The tool is described as depth in following: There are two tools, the first tool had 16 different items related to demographic information of PwDs and the second one had 18 different items are related to computer skills and ability. The second questionnaire was a close-ended questionnaire. It was developed based upon the VAPS, BASAL-MR questionnaire developed by NIMH have questions on disability condition, management, policies, training and services available for PwDs. There are some basic areas in the tool are related to personal, academic, communication, vocational and recreational skills. The researcher had sent the questionnaire to the seven expert members related to disability for modifications. The researcher had modified and improved the tool as per expert advice. The role of the researcher in this research was to pose the research question and create conducive atmosphere to discourse, in order to encourage the participants to give the answer correctly. The researcher had prepared findings and a conclusion on the basis of the score obtained by PwDs. For the second phase of research, the researcher conducted interview with PwDs to assist the information related to computer skill training and importance in vocational potential for PwDs Participants: The sample selected for the study was 50 PwDs participants including 36 female and 14 male participants with benchmark disability (above 17 years of age) enrolled in the vocational unit in Uttar Pradesh. Purposive sampling was used for sample selection. Procedure: At the beginning, the investigator met with the concerned authority of the respective institutions for identifying the PwDs. And researcher had also contacted to parents and PwD for the present study. The data were also gathered by interviewing PwDs with help of their parents and PwDs. The investigator interviewed them by the help of self-made tools. On the whole, 50 individuals with disability were interview for present study.
Findings
The PwD mostly depends upon their family due to lack of job or livelihood skills. Anyone can obtain a job/business with help of vocational training or job training. In order to live an independent life, with social surroundings, basic vocational skills is desirable. PwDs is able to hold gainful employment or manage their daily financial activities with computer skills easily. ICT skills are very easy and useful to reading and writing, understand decision-making, logical thinking, problem-solving and so on.
Research limitations/implications
The future research may guide parents and service providers, belonging from different geographical areas how to train the PwD. The study will indicate researches to guide parents to select appropriate job options for a PwD. Resources related to computer training for PwDs are very limited. In future, the research may conducted in specific disability for better output.
Practical implications
This study plays an important role in the vocational training of a PwD. Computer-based training model is easily implementable, cost-effective and accessible all over India. With help of new technology, the vocational training becomes systematic and structured for PwDs. Individual and group guidance is available for large and small groups all over India for PwDs. Computer-based instructions are clear and easy instructions for PwDs, and it avoids the unnecessary confusion of parents regarding the vocational training programmes of their PwDs. Computer-based vocational training is helpful for better employment options for PwD.
Social implications
The attitudinal barrier will be reduced with computer training. The study will help in the training of the PwDs in different job roles. Computer training in the vocational curriculum will make the training part easy for trainers and PwDs as per his requirements. There are many organizational barriers to technology adoption are particularly problematic given the growing demands and perceived benefits among students about using technology to learn.
Originality/value
This paper adds new and significant information since it focuses on a specific group of persons who are disabled and the significance of using technology in learning. In conclusion, the findings in this study have valuable implications for PwDs, special educators and parents. This study creates effective in increasing positive atmosphere for PwDs in society and increases inclusion at vocational training centres. Therefore, it is important for technology base vocational training and education.

Abstract
Purpose
The assembly simulation in tolerance analysis is one of the most important steps for the tolerance design of mechanical products. However, most assembly simulation methods are based on the rigid body assumption, and those assembly simulation methods considering deformation have a poor efficiency. This paper aims to propose a novel efficient and precise tolerance analysis method based on stable contact to improve the efficiency and reliability of assembly deformation simulation.
Design/methodology/approach
The proposed method comprehensively considers the initial rigid assembly state, the assembly deformation and the stability examination of assembly simulation to improve the reliability of tolerance analysis results. The assembly deformation of mating surfaces was first calculated based on the boundary element method with optimal initial assembly state, then the stability of assembly simulation results was assessed by the density-based spatial clustering of applications with noise algorithm to improve the reliability of tolerance analysis. Finally, combining the small displacement torsor theory, the tolerance scheme was statistically analyzed based on sufficient samples.
Findings
A case study of a guide rail model demonstrated the efficiency and effectiveness of the proposed method.
Research limitations/implications
The present study only considered the form error when generating the skin model shape, and the waviness and the roughness of the matching surface were not considered.
Originality/value
To the best of the authors’ knowledge, the proposed method is original in the assembly simulation considering stable contact, which can effectively ensure the reliability of the assembly simulation while taking into account the computational efficiency.

Abstract
Purpose
Disasters and armed conflict often co-occur, but does that imply that disasters trigger or fuel conflict? In the small but growing body of literature attempting to answer this question, divergent findings indicate the complex and contextual nature of a potential answer to this question. The purpose of this study is to contribute a robust cross-country analysis of the co-occurrence of disaster and conflict, with a particular focus on the potential role played by disaster.
Design/methodology/approach
Grounded in a theoretical model of disaster–conflict co-occurrence, this study merges data from 163 countries between 1990 and 2017 on armed conflict, disasters and relevant control variables (low human development, weak democratic institutions, natural resource dependence and large population size/density).
Findings
The main results of this study show that, despite a sharp increase in the co-occurrence of disasters and armed conflict over time, disasters do not appear to have a direct statistically significant relation with the occurrence of armed conflict. This result contributes to the understanding of disasters and conflicts as indirectly related via co-creation mechanisms and other factors.
Originality/value
This study is a novel contribution, as it provides a fresh analysis with updated data and includes different control variables that allow for a significant contribution to the field.
