In this study, the research question posed was: What are the defining characteristics, limitations, and potential opportunities in the research on heterogeneity within ASD?

This scoping review used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology to address the research question: “What are the defining characteristics, limitations, and potential opportunities in the research on heterogeneity within ASD?” A comprehensive literature search was conducted across databases including MEDLINE/PubMed, SciVerse Scopus and Springer Link, with keywords such as autism, autism spectrum disorder (ASD), heterogeneity and neurodevelopment. Inclusion criteria covered original research, reviews and protocols published since 1990, while irrelevant or out-of-date works were excluded. Thematic analysis was applied to collected data to identify common patterns, trends and key characteristics, leading to a narrative synthesis. Ethical review board approval was not required due to the nature of the review.

The scoping review underscored the multifaceted nature of ASD, emphasizing its clinical, methodological and investigational complexities. ASD’s diverse behavioral, social and biological characteristics challenged its classification as a uniform entity. To address this, the review examined strategies like stricter clinical criteria, categorization into functional subgroups, and larger, diverse sample sizes. Moreover, it highlighted the transformative role of Big Data and machine learning in advancing the comprehension of ASD’s manifold manifestations. This research contributed valuable insights and innovative approaches for addressing the intrinsic heterogeneity of ASD, reshaping the understanding of this complex condition.

One limitation of this scoping review is that it primarily relied on existing literature and did not involve primary data collection. While the review synthesized and analyzed a substantial body of research, the absence of original data collection may limit the depth of insights into specific aspects of ASD heterogeneity. Future research could benefit from incorporating primary data collection methods, such as surveys or interviews with individuals with ASD and their families, to gain more nuanced perspectives on the condition’s heterogeneity.

The reliance on existing literature in this scoping review highlights the need for further empirical studies exploring ASD’s heterogeneity. Researchers should consider conducting primary data collection to capture real-world experiences and variations within the ASD population. This approach could provide more comprehensive and context-specific insights, ultimately informing the development of tailored interventions and support strategies for individuals with ASD and their families.

This paper offers a fresh perspective on understanding ASD by examining its clinical, methodological and investigational implications in light of its inherent heterogeneity. Rather than viewing ASD as a uniform condition, this study explores strategies such as stricter clinical criteria, subcategorization based on functionality and diverse sample sizes to address its complexity. In addition, this study highlights the innovative use of Big Data and machine learning to gain deeper insights into ASD’s diverse manifestations. This approach contributes new insights and promising directions for future research, challenging the conventional understanding of ASD as a singular entity.

Previous research has evidenced that communication design students wish to engage further with sustainable practices but struggle to understand how (Newton and Ellis, HER conference 2023). Whereas other design disciplines (fashion, product, furniture) can often focus on a “physical” output, communication design embraces multiple outcomes, distributed throughout a range of platforms, representing an area of industry and study which can prove difficult to define. This study aims to add further clarity as to how students consider sustainability aligned to their practice.

Previous focus group research sought to uncover how communication design students implicitly consider “sustainability”, uncovering that their knowledge is limited. Suggestions from participants emphasised that it was the role of the institution, not the student, to fully integrate sustainability into practice and to define methods they can deploy. This paper notes a subsequent workshop conducted with 33 Level 5 undergraduate students asking them to reflect on Sustainable Development Goals (SDGs) 12/13 in relation to meaningful practice and institutional responsibility.

Workshops demonstrated the need to engage with sustainable thinking throughout every stage of development. It is clear that students demand more from academic staff at programme level, and from the institution at large, to provide further solutions to sustainability concerns which are relevant to their specific practice.

Discussion surrounding pedagogical practice across communication design lacks interrogation, yet the discipline represents a significant aspect of both design and contemporary society. It is paramount that methods for reinforcing implicit engagement with sustainable best practice within students, their development and their future beyond university are therefore developed.

Although prior research has shown the influence of the degree of simplicity (versus complexity) in packaging design on consumer’s product and brand perceptions, no research to date has analyzed the effect of minimalist packaging on perceived product naturalness. This research thus aims to investigate the underlying mechanisms explaining how a minimalist food packaging design may lead consumers to perceive a product as more natural.

The paper is based on two pre-tests and two experiments (N = 152 and N = 220) focusing on food products. Serial–parallel mediations are performed to test the effect of minimalist packaging design on perceived product naturalness.

In a food consumption context, we demonstrate and replicate the positive impact of minimalism on perceived product uniqueness, which then positively influences both production mode and perceived taste, which, in turn, increases perceived product naturalness.

The findings provide new insights into the influence of food packaging design on consumers’ product perception. This paper offers a deeper understanding of the relationship between minimalist food packaging design and product naturalness by highlighting the mediating roles of perceived uniqueness, production mode and perceived taste.

This paper examines the efforts of National Health Service (England) (NHSE) to respond to employee-based racial inequalities via its Workforce Race Equality Standard (WRES). The WRES constitutes a hybridised accountability initiative with characteristics of the moral and imposed regimes of accountability.

The study conceptualises the notion of responsive race accountability with recourse to Favotto et al.’s (2022) moral accountability model and critical race theory (CRT), and through it, examines the enactment of WRES at 40 NHSE trusts using qualitative content analysis.

Despite the progressive nature of the WRES that seeks to nurture corrective actions, results suggest that trusts tend to adopt an instrumental approach to the exercise. Whilst there is some evidence of good practice, the instrumental approach prevails across both the metric reporting that trusts engage in to guide their actions, and the planned actions for progress. These planned actions not only often fail to coalesce with the trust-specific data but also include generic NHSE or equality, diversity and inclusion initiatives and mimetic adoptions of best practice guidance that only superficially address racial concerns.

Whilst the WRES is a laudable voluntary achievement, its moral imperative does not appear to have translated into a moral accountability within individual trusts.

Responding to calls for more research at the accounting-race nexus, this study uniquely draws on CRT to conceptualise and examine race accountability.

This study examines the effect of social media marketing on voting intention applying a combination of fuzzy logic methodology and a multidimensional panel data model.

The study adopts a multidimensional panel data method that includes several fixed effects. The dependent variable is a multifaceted construct that measures the participants’ intention to vote. The independent variables are electronic word of mouth (eWOM), customisation (CUS), entertainment (ENT), interaction (INT), trendiness (TRD), candidate’s perceived image (CPI), religious beliefs (RB), gender and age. The grouping variables that signify fixed effects are employment status, level of education, mostly used social media and religion. First, the significance of said fixed effects was tested through an ANOVA process. Then, the main model was estimated, including the significant grouping variables as fixed effects.

Employment status and level of education were significant fixed effects. Also, eWOM, ENT, INT, CPI, RB and gender significantly affected participants’ voting intention.

Being based on a questionnaire that asked participants about how they perceive different aspects of social media, the present study is limited to their perceptions. Therefore, further studies covering the voters’ behaviour in action could be efficient complements to the present study.

The findings could guide the political parties into prioritizing the aspects of social media in forming an effective campaign resulting in being elected.

The findings have the potential to help the public in making better informed decisions when voting. Furthermore, the results of this study indicate applications for social media which are beyond leisure time fillers.

Fuzzy logic and multidimensional panel data estimates are this study’s novelty and originality. Structural equation modelling and crisp linguistic values have been used in previous studies on social media’s effect on voting intent. The former refines the data gathered from a questionnaire, and the latter considers the possibility of including different grouping factors to achieve a more efficient and less biased estimation.

Generative conversational artificial intelligence (AI) demonstrates powerful conversational skills for general tasks but requires customization for specific tasks. The quality of a custom generative conversational AI highly depends on users’ guidance, which has not been studied by previous research. This study uses social exchange theory to examine how generative conversational AI’s cognitive and emotional conversational skills affect users’ guidance through different types of user engagement, and how these effects are moderated by users’ relationship norm orientation.

Based on data collected from 589 actual users using a two-wave survey, this study employed partial least squares structural equation modeling to analyze the proposed hypotheses. Additional analyses were performed to test the robustness of our research model and results.

The results reveal that cognitive conversational skills (i.e. tailored and creative responses) positively affected cognitive and emotional engagement. However, understanding emotion influenced cognitive engagement but not emotional engagement, and empathic concern influenced emotional engagement but not cognitive engagement. In addition, cognitive and emotional engagement positively affected users’ guidance. Further, relationship norm orientation moderated some of these effects such that the impact of user engagement on user guidance was stronger for communal-oriented users than for exchange-oriented users.

First, drawing on social exchange theory, this study empirically examined the drivers of users’ guidance in the context of generative conversational AI, which may enrich the user guidance literature. Second, this study revealed the moderating role of relationship norm orientation in influencing the effect of user engagement on users’ guidance. The findings will deepen our understanding of users’ guidance. Third, the findings provide practical guidelines for designing generative conversational AI from a general AI to a custom AI.

This paper aims to examine how visual elements used in packaging design relate to diasporic consumer identity and influence aesthetic appreciation.

Drawing on social identity theory, research on aesthetic principles and using a mixed methods approach, two studies are conducted. Study 1 involves a qualitative exploration of the nature of diasporic consumer identity and its relation with visual design in packaging. Study 2 involves quantitative testing and calibration of this relationship and its subsequent influence on aesthetic appreciation.

Diasporic consumers from the Middle East appreciate hybrid visual designs and prefer packaging that strikes an optimum balance of visual elements (colour, shapes, patterns) from the heritage aspects of their ancestral homeland and more contemporary aspects from their culture of living. Preference for balance elicits an overall positive diasporic identity feeling that mediates the relationship with aesthetic appreciation of visual design in packaging.

These findings offer new knowledge about the role of visual design in packaging in delivering symbolic value to diasporic consumers, evidencing how diasporic consumers’ dual identities shape aesthetic appreciation and preferences for hybrid visual designs.

Provides marketing practitioners and packaging designers with a concise and contextual directive for creating visual designs that appeal to a growing segment of diasporic consumers.

This research draws on social identity theory to uncover an aesthetic cultural precept – heritage, yet contemporary – that can inform the development of packaging designs targeting diasporic consumers.

A novel phenomenon in product and service promotions, social coupons facilitate group buying at lower prices, bringing key benefits to customers, merchants and coupon aggregators. This study maps the evolution and innovations in social couponing, identifies knowledge gaps in the domain and sets the future research agenda.

Through a detailed systematic literature review and bibliometric analysis, this study maps the evolution of social coupons over time. The analysis examines social coupon research by studying research outputs by authors, institutes, countries and research themes. It also explores how the social couponing phenomenon has benefited the three key stakeholders: customers, merchants and coupon aggregators.

An innovation in couponing, social coupons are discount coupons that feature group buying, pre-purchase and daily deals. Based on the extensive review of extant literature, the study proposes a conceptual model for the social couponing process. The study also provides inputs for future research on social coupons and delineates their academic and managerial implications.

This study makes a pioneering endeavor to comprehensively map the knowledge structure of social coupons from multiple dimensions.

In response to the growing significance of diversity advertising, this study aims to investigate its impact on audience connectedness. This is an emerging metric crucial for gauging diversity advertising success. The study explores two paths via self-identification and belief congruence to understand how diversity advertisements resonate with individuals.

A quantitative study using partial least squares with survey data from 505 respondents was conducted.

Self-identification and belief congruence mediate the relationship between perceived diversity and audience connectedness. Belief congruence exhibits a stronger influence. Further, brand engagement reduces the relationship between belief congruence and connectedness. However, it strengthens the relationship between self-identity and connectedness.

Future research should address why belief congruence holds more significance than self-identification. Additionally, research must explore the societal effects of diversity advertising, including strategies to engage those who feel disconnected.

The study underscores the positive social effects of diversity advertising for both marginalized and nonmarginalized audiences. It urges marketers to pursue audience connectedness. Strategies for achieving this include reflecting their target audience’s beliefs, perhaps highlighting real and lived experiences. Marketers should also consider self-identification through visual cues and customized messaging.

The study applies self-referencing theory to unravel the relationship between diversity advertising and audience connectedness. It reinforces the role of self-identification and expands the knowledge by demonstrating how connectedness can emerge through belief congruence. Additionally, the authors explore the subtle influence of brand engagement, a critical brand-related factor that shapes individuals’ responses to diversity advertising.

Surgical services are settings where resilient performance (RP) is necessary to cope with a wide range of variabilities. Although RP can benefit from a supportive built environment (BE), prior studies have focused on the operating room, giving scant attention to support areas. This study takes a broader perspective, aiming at developing BE design knowledge supportive of RP at the surgical service as a whole.

Seven BE design prescriptions developed in a previous work in the context of internal logistics of hospitals, and thus addressing interactions between workspaces, were used as a point of departure. The prescriptions were used as a data analysis framework in a case study of the surgical service of a medium-sized private hospital. The scope of the study included surgical and support areas, in addition to workflows involving patients and family members, staff, equipment, sterile instruments and materials, supplies, and waste. Data collection included document analysis, observations, interviews, and meetings with hospital staff.

Results identified 60 examples of using the prescriptions, 77% of which were related to areas other than the operating rooms. The developed design knowledge is framed as a set of prescriptions, examples, and their association to workflows and areas, indicating where it should be applied.

The design knowledge is new in surgical services and offers guidance to both BE and logistics designers.
