Epoxy resin (EP) is a thermosetting resin commonly characterized by its inherent brittleness, which limits its widespread application. To overcome this limitation, a novel flexible chain-blocking hyperbranched polyester (HBP) was conceptualized and synthesized to enhance the toughness and dielectric properties of EP.

Using P-toluene sulfonic acid (p-TSA) as the catalyst and Bis(hydroxymethyl)propionic acid (DMPA) as the branching unit with pentaerythritol (PER) as the core, an experimental synthesis was conducted. Subsequently, n-hexanoic acid was introduced separately to produce hyperbranched polyester with n-hexanoic acid capped structures. Microstructural, mechanical, insulating and dielectric analyses of the composite were performed to determine the optimal proportion of HBP.

Recent research has demonstrated that the flexible segments within hyperbranched polyester create an interpenetrating network structure with the molecular chains of epoxy resin, thereby effectively augmenting the toughness of the epoxy resin. Additionally, HBP has reduced the ε and tgδ values of the epoxy-anhydride cured product by decreasing the number of polar groups per unit volume of EP through the introduction of free volumes.

Currently, HBP serves as an innovative toughening strategy and modifier for epoxy resin. The toughening mechanism involves the generation of free volume by HBP, providing space for EP molecules to maneuver under load. Additionally, the free volume contributes to a reduction in the dielectric constant of EP by diminishing the polarizable group content. Simultaneously, the incorporation of HBP features flexible chains grafted onto the epoxy resin.

The purpose of this study is to examine the state of the literature related to the psychophysiological effects of travel, to identify gaps in the literature and to propose a vision to guide research between now and 2050.

The study was guided by a systematic literature review which started with more than 2,100 papers. The extant review and its findings are written in a conceptual nature with the concluding propositions, for the year 2050, guided by the systematic review and the authors’ personal knowledge.

It was found that research related to the psychophysiological effects of travel has greatly progressed over the past two decades. Findings include evidence that travel reduces both perceived and actual stresses and that taking more vacations has the ability to make people healthier. The study also revealed that travel can have negative effects on physiological health. The overall results led to a call for research on the psychophysiological benefits of travel between now and 2050.

The systematic review of literature was limited to studies conducted in English and to studies that included the words “travel” or “tourism” and “benefits”, stress, “health” and “wellness”. Results provide a discussion of theories that should guide the research agenda.

The review and proposed vision for research provide a detailed guide for researchers to follow. Should the proposed research come to fruition, tourism practitioners globally will have results to aid in engineering tourism experiences that could provide health benefits to visitors.

The proposed vision could have profound social implications, as the understanding of the positive and negative effects of travel should make travel experiences healthier for all. The study also proposes a call for research to determine ways to make the benefits of travel available to both the “haves” and “have nots” so that the benefits of travel can be more inclusive.

The main contribution of this manuscript is that it proposes 11 propositions for research between now and 2050 based on a thorough review of gaps related to the psychophysiological benefits of travel. The resultant propositions provide a clear and unique call for research in this area of inquiry.

This research aims to examine the relationship between the physical environment and neuropsychological perception in children with Asperger’s disorder.

This study through mixed qualitative–quantitative approaches conducted strategies including a survey and case study. Accordingly, multiple methods were applied to collect data including semi-structured expert interviews (20 persons) and questionnaires (N = 400). The sampling strategy of questionnaire participants was random clustering and the target population was children with Asperger from Iran Asperger Support Associations. Besides, the sampling strategy for the participants of semi-structured expert interviews was non-random and purposeful. The collected data from the participant’s questionnaires and interviews were analyzed by Porsline and Excel software and content analysis, respectively.

Based on the relationship between the physical environment and neuropsychological perception, the results of the research indicate that despite all existing differences between the two spectra of hyper-sensitive and hypo-sensitive behaviors, it is possible to design architectural spaces responding to their common needs and satisfy both spectra.

This research on to healing aspect is quite new and contributes significant information about health issues in building design. This study tries to derive and examine the supportive characteristics of architectural spaces that integrate special physical and effective designs to improve the healing process of children with Asperger’s disorder.

This research aims to develop and validate a framework for eradicating women’s discrimination in architectural design firms (ADFs) in Egypt and propose strategies for prospective adoption in the Gulf Cooperation Council (GCC) countries to increase the transformational impact of women on the architectural and urban developments of the Gulf region.

A combined qualitative and quantitative research approach was designed to accomplish four objectives. Firstly, to investigate the nature of business in ADFs, women’s discrimination and policies for gender equity (PGE) in architecture. Secondly, to analyse three case studies to validate the identified causes and impacts of women’s discrimination and examine the role of PGE towards eradicating women’s discrimination in ADFs. Thirdly, to conduct a survey questionnaire with a representative sample of ADFs to investigate their perception of women’s discrimination and the correlation between PGE towards eradicating women’s discrimination in ADFs. Based on the above, the research developed and validated a framework to eradicate women’s discrimination in ADFs in Egypt and suggested strategies for potential application in the GCC countries to increase the transformational role of women in the architectural and urban developments of the Gulf region.

Through literature review and case studies, the research identified and validated the causes and impacts of women’s discrimination as well as PGE in Architecture. The findings of data analysis showed that the highest-ranked causes of women discrimination in ADFs were “customs and beliefs” followed by “Underestimating women’s work” and “Recruiting males more than females”. Moreover, the highest-ranked impacts of women’s discrimination were “career shift and leaving the profession” followed by “decrease in creativity and innovation” and “decrease in economic growth”. Furthermore, the Spearman correlation test showed that while some PGE were correlated, others were not. These findings helped in the development of the proposed framework and proposed strategies.

This research presents a practical framework to eliminate women’s discrimination in ADFs in Egypt based on the findings of literature review, case studies and survey questionnaire. The framework explained in a workable way the objectives of the framework functions; activities; tools and techniques; involved personnel and needed resources as well as enforcing mechanisms. It was validated by a representative sample of ADFs in Egypt to ensure its practicability and viability and suggested strategies for implementation in the GCC countries to increase women’s role in architectural and urban development.

The research identified and validated the causes and impacts of women’s discrimination as well as PGE in Architecture. Moreover, the research investigated the perception of women’s discrimination and the correlation between PGE through conducting a survey questionnaire with a representative of ADFs in Egypt. The research tackled a topic that received scant attention in construction literature, especially in Egypt and the GCC countries. The research developed and validated a framework to eradicate women’s discrimination in ADFs in Egypt. 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. The research suggested several strategies for the prospective implementation of the framework in the GCC countries as an approach to enhancing the transformational role of women in the architectural and urban developments of the Gulf region.

This paper proposes a structural model that explores the relationship between game/esports streamers’ credibility dimensions and viewers’ willingness to spend money (WTP) on online games. The study seeks to uncover the underlying mechanisms in this relationship by drawing on the source credibility model, social identity theory and S-O-R framework.

The study utilized an online survey conducted through Qualtrics survey software to validate the proposed framework. The sample (N = 612) consisted of viewers of a Turkish esports live streamer with a substantial following on both Twitch and YouTube. The main research framework was tested using AMOS 22, and the serial mediation analyses were done using Process v3.0 on SPSS.

The findings of this study are significant, revealing that streamer credibility (SC) factors – trustworthiness, attractiveness and expertise – have a profound impact on the response variables purchase intention (PI) and WTP through streamer identification (STI). Moreover, the study uncovers that the time spent watching the streamer significantly influences WTP for games, a crucial insight for the gaming industry.

By bridging the realms of social identity theory and the source credibility model within the context of game streaming, this study charts new territory in understanding the intricate web of factors shaping consumer behaviour in live-stream gaming environments. It highlights the multifaceted nature of viewer-streamer interactions and their implications for marketers and industry stakeholders seeking to navigate the expanding landscape of live stream commerce.

This paper offers a novel structural framework that synthesizes multiple perspectives to investigate the relationship between esports streamers’ credibility and viewers’ spending behaviour. By incorporating concepts from the source credibility model, social identity theory and S-O-R framework, the study not only expands upon existing theories of identity in the streaming domain but also provides a comprehensive understanding of the factors influencing consumer behaviour in online gaming environments.
