While some countries have used debt to drive economic growth, the asymmetric effect on sub-Saharan African (SSA) countries has received little attention in the empirical literature. This paper therefore examines the asymmetric effect of external debts on economic growth.

The panel nonlinear autoregressive distributed lag (NARDL) approach was employed in the study for 29 sub-Saharan African countries from 1990 to 2021. The cross-sectional dependence test was used to determine the presence of cross-sectional dependence, while the second-generation panel unit root tests was used to examine the unit-root properties.

The empirical results show that external debt has an asymmetric effect on economic growth in both the short and long run. In the long run, a positive shock in external debts of 1% triggers an upturn in economic growth by 0.216% while a negative shock triggers 0.354% decline in economic growth. This implies that the negative shock of external debts has a much stronger impact on economic growth than the positive shock. In the short run, a positive shock in external debts by 1% triggers a decline in economic growth by 0.641%, while a negative shock of 1% triggers a fall in economic growth of 0.170%.

The paper used the NARDL model to examine the asymmetric impact of external debt on the economic growth of SSA countries, which has not been extensively studied. It is recommended that governments in the selected countries in sub-Saharan Africa should drive economic growth by promoting domestic revenue mobilization since external debts impede economic growth.

Systematic efforts to study students' use of informal learning spaces are crucial for determining how, when and why students use such spaces. This case study provides an example of an effort to evaluate an informal learning space on the basis of students' usage of the space and the features within the space.

Use of heatmap camera technology and a semi-structured interview with a supervisor of an informal learning space supported the mixed-methods evaluation of the space.

Findings from both the heatmap outputs and semi-structured interview suggested that students' use of the informal learning space is limited due to the location of the space on campus and circumstances surrounding students' day-to-day schedules and needs.

Findings from both the heatmap outputs and semi-structured interview suggested that students' use of the informal learning space is limited due to the location of the space on campus and circumstances surrounding students' day-to-day schedules and needs. These findings are actively contributing to the authors’ institution’s efforts surrounding planning, funding and design of other informal learning spaces on campus.

While most research on instructors' and students' use of space has taken place in formal classrooms, some higher education scholars have explored ways in which college and university students use informal spaces around their campuses (e.g. Harrop and Turpin, 2013; Ramu et al., 2022). Given the extensive time students spend on their campuses outside of formal class meetings (Deepwell and Malik, 2008), higher education institutions must take measures to better understand how their students use informal learning spaces to allocate resources toward the optimization of such spaces. This mixed-methods case study advances the emerging global discussion on how, when and why students use informal learning spaces.

The purpose of this paper is to investigate the ending of fee-free higher education in Australia for overseas students in the 1980s, and the ways in which the government managed the diplomatic relationships that were affected by this policy shift. The introduction of fee-free higher education in Australia in 1974 was incredibly popular, and the end of the program in the late 1980s created difficulties for individuals, families and diplomatic relationships.

Using a mix of secondary sources and archival documents, this paper has a historiographical element, and an element of analysis.

This research finds that the ending of fee-free education created significant diplomatic issues with a number of Australia’s regional neighbours. It also created issues for individual students and families. The solution to these problems was, in large part, a scholarship scheme called the Equity and Merit Scholarship Scheme (EMSS). The EMSS was designed, in part, to address the issues created by the end of the fee-free program. However, the design of the scholarship scheme also created its own diplomatic issues with a different cohort of nation states.

There is limited scholarly research into the history of international education policy in Australia. This research draws on the work of some scholars of international scholarships, as well as historians of universities and education more broadly. This research adds to a growing body of work in the field of Australian international education history.

The Metaverse is rapidly reshaping the understanding of tourism, yet the public perception of this new domain remains largely uncharted empirically. This paper aims to build on the technology acceptance model (TAM) and diffusion of innovations theory (DIT) to fill this gap, offering crucial insights that could inform scholars and practitioners in both the tourism and technology sectors.

Using a big-data approach, the authors applied machine learning to scrape comments made by social media users on recent popular posts or videos related to tourism in the Metaverse from three prominent social media platforms. The cleaning process narrowed down 15,461 comments to 2,650, which were then analysed using thematic, emotion and sentiment analysis techniques.

The thematic analysis revealed that virtual tourism evokes a complex range of public beliefs. While many express awe and excitement toward its immersive capabilities, others remain sceptical about authenticity compared to physical travel. Additional themes show people draw comparisons to real-world tourism, discuss technology’s role and note educational value and novelty. However, some comments raise concerns about potential societal harms, exploitation and mental health impacts. Sentiment analysis found over half of the comments positive, though some were negative. Emotion analysis showed contentment, happiness and excitement as most frequent, though sadness, worry and loneliness also featured. Overall, perceptions of Metaverse tourism encompass enthusiasm yet substantial ambivalence.

To the best of the authors’ knowledge, this study is one of the first to comprehensively analyse public discussions on Metaverse tourism. It takes TAM and Rogers’s DIT a step further and provides fresh insights into how these theories can be employed in the emerging field of Metaverse tourism. The themes revealed new conceptual insights into multidimensional factors shaping public beliefs about Metaverse tourism and thus informing scholarly research on virtual interaction and technology acceptance regarding Metaverse tourism. In addition, the results can help tourism providers, platforms and marketers address salient public beliefs and sentiments/attitudes in developing marketing offerings, experiences and communications. Over time, this analysis methodology can be used to track the evolving public perceptions of Metaverse tourism.

Scholars have underscored the importance of organizational authenticity, but it is unclear how it influences the links among market strategy, and nonmarket strategy (NMS) and firm performance. This study addresses this gap in the literature.

A survey of 294 managers in firms based in the United States investigates configurations among competitive strategy (e.g. cost leadership or differentiation), political and social nonmarket strategy (NMS), authenticity, and firm performance.

Cost leaders tend to engage in political nonmarket strategy (PNMS), but the interaction does not necessarily improve firm performance. Differentiators are more likely to pursue social nonmarket strategy (SNMS) and perform better, but neither market-nonmarket strategy configuration is inherently optimal.

The results support market-nonmarket strategy configurations but do not prescribe optimal combinations. However, the sample is cross-sector and employs self-reports for firm performance.

Political and social authenticity can enhance firm performance, but nonmarket activity can compromise a firm’s ability to be politically and socially authentic. Authenticity can drive performance, but a firm’s nonmarket activity can compromise its ability to be politically and socially authentic. Firms should view a prospective loss in authenticity as a potential cost of nonmarket activity.

This paper investigates how a firm’s emphasis on market (competitive) strategies, political and social nonmarket strategies, and political and social authenticity impact financial and non-financial performance. It also tests the veracity of two market-nonmarket configurations, cost leadership with political NMS and differentiation with social NMS.

Net zero energy buildings (NZEBs) play a crucial role in mitigating the environmental impact of the construction industry. However, this concept in Ghana is still in the infancy stage, and the level of embracement in the construction industry is uncertain which further poses challenges to its adoption. This can be attributed to the lack of awareness of NZEB among construction professionals. Hence, understanding the awareness among construction professionals is essential for promoting sustainable building practices and reducing the carbon footprint of buildings. Therefore, this study investigates the level of awareness of NZEBs among construction professionals in the Ghanaian construction industry (GCI).

The study adopted a quantitative research method where questionnaire survey was used to obtain data from sixty-six (66) construction professionals in the GCI through snowball sampling technique. The collected data were analysed using frequencies, mean scores, one-sample t-test and cross-tabulation.

The study revealed that thirty (30) construction professionals out of the sixty-six (66) had a moderate level of awareness of NZEBs, and 14 professionals had a low level of awareness. Thirteen had a high level of awareness. Three of the profesionals were extremely unaware, while six had a very high level of awareness. The study’s findings highlight the need to create awareness of NZEBs and their practices among construction professionals and employees in Ghana.

NZEB is an under-explored area in the Ghanaian context and therefore, this study uniquely highlights the nascent awareness of NZEBs among Ghanaian construction professionals, unlike previous studies in more developed contexts. It underscores the critical need for targeted awareness programs essential for reducing the carbon footprint and advancing the adoption of NZEBs in the GCI.

Autonomous vehicles (AVs) have the potential to transform the infrastructure, mobility and social well-being paradigms in New Zealand (NZ) amid its unprecedented population and road safety challenges. But, public acceptance, co-evolution of regulations and AV technology based on interpersonal and institutional trust perspectives pose significant challenges. Previous theories and models need to be more comprehensive to address trust influencing autonomous driving (AD) factors in natural settings. Therefore, this study aims to find key AD factors corresponding to the chain of human-machine interaction (HMI) events happening in real time and formulate a guiding framework for the successful deployment of AVs in NZ.

This study utilized a comprehensive literature review complemented by an AV users’ study with 15 participants. AV driving sprints were conducted on low, medium and high-density roads in Auckland, followed by 15 ideation workshops to gather data about the users’ observations, feelings and attitudes towards the AVs during HMI.

This research study determined nine essential trust-influencing AD determinants in HMI and legal readiness domains. These AD determinants were analyzed, corresponding to eight AV events in three phases. Subsequently, a guiding framework was developed based on these factors, i.e. human-machine interaction autonomous driving events relationship identification framework (HMI-ADERIF) for the deployment of AVs in New Zealand.

This study was conducted only in specific Auckland areas.

This study is significant for advanced design research and provides valuable insights, guidelines and deployment pathways for designers, practitioners and regulators when developing HMI Systems for AD vehicles.

This study is the first-ever AV user study in New Zealand in live traffic conditions. This user study also claimed its novelty due to AV trials in congested and fast-moving traffic on the four-lane motorway in New Zealand. Previously, none of the studies conducted AV user study on SUV BMW vehicle and motorway in real-time traffic conditions; all operations were completely autonomous without any input from the driver. Thus, it explored the essential autonomous driving (AD) trust influencing variables in human factors and legal readiness domains. This research is also unique in identifying critical AD determinants that affect the user trust, acceptance and adoption of AVs in New Zealand by bridging the socio-technical gap with futuristic research insights.

The current adverse changes in climatic conditions have necessitated innovative nature-based solutions like blue-green roofs to ensure sustainable built environments. The use of blue-green roofs in combating climate change issues has continued to grow, and its benefits are showcased in many countries' studies. However, there is an absence of reports on the use of this approach in South Africa. Therefore, in ensuring a sustainable built environment through nature-based solutions, this study explored the built environment professional’s knowledge of blue-green roofs, the hindrances to their use and motivations for much wider use of blue-green roofs in the country.

Based on the nature of the study, a quantitative design was adopted and data were obtained from professionals within the built environment through a questionnaire. Data analyses were conducted using the Cronbach alpha test, Kruskal–Wallis H-Test, exploratory factor analysis and fuzzy synthetic evaluation.

The findings revealed a growing knowledge of blue-green roofs, albeit its slow adoption in the country. Also, five critical clusters of hindrances affecting the use of blue-green roofs were identified. These are understanding the blue-green roof concepts, technical, economic, regulation and client hindrances. Furthermore, the ability to manage stormwater properly, provide climate change adaptation and deliver sustainable buildings were the key motivating factors that could drive the use of this innovative solution.

This study offers actionable insights for built environment professionals and stakeholders to address the hindrances to using blue-green roofs in South Africa. Strategies such as improved education, financial incentives and policy development can help overcome some notable hindrances and promote the widespread adoption of blue-green roofs.

The slow adoption of blue-green roofs and the scant nature of research within the built environment required adequate attention to which this current research contributes. Theoretically, being one of the foremost studies in South Africa to explore blue-green roofs, the findings offer a foundation for future studies seeking to explore this roofing system in the country further.

The objective of this paper is to explore the development of the Blackmail-as-a-Service business model within the Digital Thrift Shop. This service model involves the sale of doxing files to customers, as well as the removal of the content from the shop and its dissemination to victims or individuals closely connected to them.

To access the Digital Thrift shop, this study relies on the Tor browser and a darknet indexing site. The authors then use an application to collect and store the web pages as PDFs. Finally, content analysis is performed on these PDFs to understand the Blackmail-as-a-Service business model developed by the Digital Thrift.

The doxing data available on the Digital Thrift is primarily targeted toward women. Digital Thrift has also established a way to value the purchase, sale and the removal of blackmail data. The presence of Blackmail-as-a-Service on darknet sites poses unique challenges for criminal justice agencies in terms of jurisdiction, due to the lack of harmonized laws and the obstacles involved in taking down content from darknet sites. Finally, the use of a service model for blackmail allows criminals without technical skills to engage in cyber-victimization using blackmail.

Research into Blackmail-as-a-Service from boutique providers has not been conducted. To the best of the authors’ knowledge, this is one of the first study seeking to understand the Blackmail-as-a-Service business model on the darknet when used to target adults. This study presents evidence of a lack of connection between the buyers of the compromising material and the potential victim, challenging preconceived notions about image-based sexual abuse and its connection to individuals involved in interpersonal relationships.

In the process of one stop border posts (OSBP), market access is dynamic. In this context, administrative practices and cross-cultural competence among traders are crucial for market access. However, there is limited research on how cross cultural competences can strengthen the influence of administrative practices on market access among small traders. This study therefore aims at exploring this relationship.

This study used structured questionnaire to collect data from 328 traders of maize, onion and tomatoes at Namanga OSBP. Data were analyzed using PLS-SEM.

The results of this study imply that administrative practices and cross-cultural competences significantly and positively influence market access. Finally, cross-cultural competence is a significant positive moderator of the relationship between administrative practices and market access.

The results suggest that cross-cultural competence is a significant moderator of the relationship between administrative practices and market access. This adds new knowledge in the literature on how cross-cultural competences of the traders can strengthen the influences of administrative practices at the OSBPs for high market access.
