Abstract
Purpose
Polymer-based thermal interface materials (TIMs) are having pump out problem and could be resolved for reliable application. Solid-based interface materials have been suggested and reported. The purpose of this paper is suggesting thin film-based TIM to sustain the light-emiting diode (LED) performance and electronic device miniaturization.
Design/methodology/approach
Consequently, ZnO thin film at various thicknesses was prepared by chemical vapour deposition (CVD) method and tested their thermal behaviour using thermal transient analysis as solid TIM for high-power LED.
Findings
Low value in total thermal resistance (Rth-tot) was observed for ZnO thin film boundary condition than bare Al boundary condition. The measured interface (ZnO thin film) resistance {(Rth-bhs) thermal resistance of the interface layer (thin film) placed between metal core printed circuit board (MCPCB) board and Al substrates} was nearly equal to Ag paste boundary condition and showed low values for ZnO film prepared at 30 min process time measured at 700 mA. The TJ value of LED mounted on ZnO thin film (prepared at 30 min.) coated Al substrates was measured to be 74.8°C. High value in junction temperature difference (ΔTJ) of about 4.7°C was noticed with 30 min processed ZnO thin film when compared with Al boundary condition. Low correlated colour temperature and high luminous flux values of tested LED were also observed with ZnO thin film boundary condition (processed at 30 min) compared with both Al substrate and Ag paste boundary condition.
Originality/value
Overall, 30 min CVD processed ZnO thin film would be an alternative for commercial TIM to achieve efficient thermal management. This will increase the life span of the LED as the proposed material decreases the TJ values.

Abstract
Purpose
The study aims to explore how including biophilic elements in the architectural and interior design of assisted living facilities can improve the well-being and quality of life of older people. This research paper explores the concept of biophilic design and its potential benefits for assisted living facilities.
Design/methodology/approach
A total of 39 peer-reviewed articles were reviewed. The research involved a comprehensive review of databases such as Scopus, EBSCO, Elsevier, JSTOR and Google Scholar using keywords and Boolean operators with reference to the study. The study’s inclusion criteria for articles were restricted to academic articles published between 2013 and 2022. The analysis of the current research will offer insights into the concept of biophilic design research and its impact on the well-being and quality of life of baby boomers in assisted living facilities.
Findings
The research advocates the benefits of biophilic design to enhance the psychological well-being and quality of life of baby boomers dwelling in assisted living facilities. Biophilic design is a strategy that blends natural elements into built environments to improve our connection with nature to enhance the physical and psychological health of older people. In the context of assisted living facilities, where residents commonly experience a variety of physical and psychological health concerns, adopting biophilic design in architecture holds enormous promise.
Originality/value
The research focuses on applying biophilic design in assisted living facilities and its holistic approach to the overall well-being of older people. The conceptual model proposed in the study has defined the positive aspects of the biophilic design on the psychological and physiological health of older people. Few studies have been done on the impact of biophilic design, specifically on baby boomers.

Abstract
Purpose
This study explores the integration of smallholder farmers into the export market in Vietnam, an emerging economy. By introducing a prospective framework, we seek to provide insight into factors that influence this integration process.
Design/methodology/approach
This study examines the expected growth and entry of Vietnamese smallholder farmers into high-value export markets. We collected information from 200 independent farmers as well as from five local extension workers, who provided information on 50 farmers.
Findings
The study reveals that the adoption of new business models is more influential than the variables traditionally included in models of export-market integration in predicting expected growth and entry into high-value export markets. In addition, the results highlight divergent views between farmers and extension workers regarding the role of collectors, with farmers perceiving collectors as potential partners, while extension workers see them as impediments to growth.
Research limitations/implications
The prospective model presented in this study highlights the importance of policy interventions aimed at promoting new business models and addressing infrastructure and capital constraints for the sustainable transformation of agricultural sectors in emerging markets.
Originality/value
This is one of the first articles to apply a prospective approach to export-market integration and demonstrate its efficacy through an empirical study. The suggested prospective approach could facilitate the design of policies aimed at export-market integration within the context of dynamic, emerging markets.

Abstract
To effectively integrate sustainability education into accounting, the needs of stakeholders such as educators, practitioners, regulators, students, and politicians must be considered. While existing literature reflects their separate perceptions, this study considers their influence on the integration process. Sustainability accounting can play a key role in supporting sustainability practices, which businesses need to be accountable for. This study focuses on how sustainability accounting education can improve corporate sustainability practices. However, most existing studies only consider one stakeholder group, and there is a gap in literature on sustainability accounting education in developing countries, particularly in the Middle East. This study informs future researchers about various research gaps in sustainability education.

Abstract
The UK government has taken the lead in accelerating the capacity of higher education to engage with sustainability accounting and adopting a novel systematic approach toward a collective implementation of and contribution to Sustainable Development Goals (SDGs). The UN SDG 16 “Peace, Justice & Strong Institutions” promotes the (re)building of effective and accountable institutions. In line with the institutional logics metatheory, we provide empirical evidence on how the alignment between social mechanisms alongside the reputation of higher education institutions (HEIs) and SDGs on transparent and responsible service (SDG 16) affect the students' overall experience. Using a sample of 142 UK HEIs, interpretative content analysis and ordinary least squares, the results show that integrating HEIs' responsible-oriented research agenda proactively with high sustainability reputation adds significantly to greater student satisfaction.

Abstract
Purpose
This study aims to understand the utility of personas and illustrate, through a case study, how a persona-building exercise in a Community Based Prevention Marketing (CBPM) training of community leaders elicited important insights that complemented findings from ongoing formative research on vaccine hesitancy in the Hispanic/Latino population in the USA during COVID-19 pandemic.
Design/methodology/approach
An exploratory concurrent parallel qualitative study design compared three personas created by community-based organization members (n = 37) to transcripts from five formative research focus groups (n = 30) from the same project. All participants in this study were recruited by the National COVID-19 Resiliency Network as part of their capacity-building and formative research activities. Grounded theory guided the content analysis.
Findings
This study found personas and focus groups to be complementary. A high degree of co-occurrence was observed when investigating the uptake of the COVID-19 vaccine under the categories of barriers, culture and communication. Between the two methods, the authors found strong associations between fear, disruption to the value system, work-related barriers, inaccessibility to health care and information sources and misinformation. Areas of divergence were negligible.
Research limitations/implications
While personas provided background information about the population and sharing “how” to reach the priority population, focus groups provided the “why” behind the behavior, followed by “how”.
Practical implications
A community-driven persona-building process built on cultural community knowledge and existing data can build community capacity, provide rich information to assist in the creation of tailored messages, strategies and overall interventions during a public health crisis and provide user-centered, evidence-based information about a priority population while researchers and practitioners wait on the results from formative research.
Originality/value
This case study provided a unique opportunity to analyze the complementary effectiveness of two methods acting in tandem to understand the priority population: stakeholder-informed persona-building and participant-informed focus group interviews. Understanding their complementary nature addresses a time gap that often exists between researchers and practitioners during times of crises and builds on recommendations associated with bringing rigor into practice, promoting academic contribution to real-world issues and building collaborative partnerships. Finally, it supports the utility of a nimble tool that improves social marketers’ ability to know more about their audience for intervention design when time is of the essence and formative research is ongoing.

Abstract
Purpose
Several studies have attempted to explain the integration of sustainable development in business school curricula. However, little is known about who (male students vs female students), at which age (under 21, 21–25 and 26–30) and at which stage of their undergraduate education (freshman, junior or senior) can attain and retain an adequate understanding of sustainability in accounting education. For this reason, the present study aims to investigate the students' interest in sustainability in accounting with respect to their demographic factors.
Design/methodology/approach
The study used a quantitative research design where data were collected at a single point in time. Further, an independent sample t-test, one-way ANOVA and factorial design were performed on 132 responses conveniently collected from accounting students in the College of Business Administration (COBA) at Prince Mohammad Bin Fahd University (PMU) in Al Khobar, Saudi Arabia.
Findings
The study found no differences between the attitudes of male and female students toward sustainability in accounting education. Similarly, no statistical differences were found in the three age categories identified in this study. However, significant results were found throughout the different academic classifications (seniority): freshman students, junior students and senior students. Further, differences in the mean scores for freshman and junior accounting students were different between the male and female students, indicating that both male and female senior students' attitudes toward sustainability in accounting education were higher than those of male and female freshman and junior accounting students. The study concluded that students achieve an adequate understanding of sustainability in accounting education related to the relativism category of the Perry model of intellectual development.
Originality/value
Literature on attitude of students toward sustainability in education, specifically accounting education, is questionable and needs further exploration. This is due to the fact that only a small number of accounting students have been exposed to sustainable accounting education. Similarly, a recent study found a significant deficiency in sustainable accounting education in four Saudi Arabian universities, with only 4.5% of respondents knowing the comprehensive definition of sustainable development and 88% respondents having very low to low familiarity with the term sustainability.

Abstract
Purpose
The COVID-19 pandemic has created a significant disruption in the educational systems worldwide. Some institutions opted for emergency remote education due to the need to cancel in-person activities. The aims of this paper were to evaluate the use of asynchronous methodology in health sciences education, determine whether asynchronous methodology was sacrificing overall student satisfaction, and investigate whether satisfaction improved as the program develops.
Design/methodology/approach
Initially, there was phase 1 that corresponded to four weeks of activities. Each professor produced a video lesson, and after each video lesson, a weekly educational activity was made available. Next, phase 2 was implemented using the same methodology, however lasting six weeks. Three questionnaires were developed, and a Likert scale was administered to verify the students’ level of satisfaction. Data were analyzed using frequency distributions, mean values, standard deviation and confidence interval. The normality of the sum data (total of the questionnaires) was tested using the Kolmogorov–Smirnov test.
Findings
Although the students pointed out that the asynchronous methodology facilitated access to the content and considered this methodology satisfactory, they expressed a reduced level of satisfaction regarding emergency remote education in general when data from the first weeks were compared to those of the previous weeks. It is clear that students became increasingly discouraged and tired over time, which motivated the institution to shift into a combination of synchronous and asynchronous methodology to improve student learning.
Originality/value
Teaching in the field of health care encompasses difficult competencies that sometimes are impossible to be learned remotely, so there is a need to examine and evaluate properly the remote education in this area. With careful planning, educational institutions can evaluate their experiences during the pandemic, allowing those involved to highlight strengths and identify weaknesses to better prepare for future needs to improve remote education.
