“…Through structural equation modelling, they revealed that affordance derived from the mobile app significantly impacts the perceived value. Albeit in a different context, similar results can also be found in the study by Wen et al [52], where there is a significant relationship between the affordances of open-access data repositories and perceived value. They assessed this relationship through PLS-SEM, due to the suitability of the method, to test a model that contains both formative and reflective constructs.…”

“…For this reason, the matching perceptions of the values generated from the uptake of the product by the tourist can lead to significant interaction with the tourism managers, while reducing the possibilities of diminishing values (see [51]). Conceivably, individuals will be steered away from consuming or using a product if the anticipated values are less, irrespective of any other factors [52]. Reviewing past literature, little research has been done in the realm of tourism-or other fields of study-regarding the relationship between affordance and perceived value.…”

“…Therefore, it can be postulated that affordances derived from good product design may influence destination reputation and loyalty. The operationalisation of affordances can further support this through a three-phase process, as suggested by Wen et al [52]. The first phase looks at how people realise what possibilities can be actualised from a product.…”

The aim of this study is to analyse the relationships between the perceived ecotourism design affordances (PEDA), perceived value of destination experience (PERVAL), destination reputation, and destination loyalty among the tourists visiting Langkawi Island, Malaysia. It extends the affordance theory through the lens of Gestalt theory and ecological dynamics in understanding the interactions between tourists and products derived from their ecotourism environment. A quantitative approach was utilised, in which a structured questionnaire was used to collect 280 tourist responses through purposive sampling. Utilising partial least square-structural equation modelling (PLS-SEM) to test the research hypotheses, it is reported that PEDA significantly impacts PERVAL, where the latter subsequently impacts both destination reputation and loyalty. This illustrates the mediating impacts of PERVAL on the relationship between PEDA and destination reputation and destination loyalty. Another result revealed that destination reputation has a significant effect on destination loyalty. The findings address the gap in the tourism literature centered on the dynamics of product design and its subsequent value in shaping positive ecotourism destination reputation and loyalty. Such insights also emphasise the necessity for tourism stakeholders to generate values from coherent ecotourism product design through the affordance perspective.

Factors affecting the Acceptance of Video Games as a Tool to improve students’ academic performance in Physical Education

Using commercial videogames as learning objects for the development of 21st century skills in secondary schools has been a relevant topic of study in recent years. But its use in the field of physical education is especially interesting considering its nature. The aim of this article is to explore how elements like technological competence, game-based learning, accessibility, and enjoyment are relevant factors that influence the acceptance of the use of video games as a learning aid in the context of physical education, as well as their influence on academic performance in the subject itself. The study enlisted the participation of 166 secondary school students. A quasi-experimental pre-post design with a non-equivalent control group was used. The intervention consisted of a specific training program entailing nine one-hour sessions once a week. To develop the model, the data was analysed using the optimisation technique of partial least squares (PLS). Our findings show that the factors studied, which are accessibility, enjoyment, technological competence and learning through video games, have an impact on students’ acceptance of video games as an educational tool and how this positive relationship leads to enhanced academic performance in physical education.

Counteracting Dark Web Text-Based CAPTCHA with Generative Adversarial Learning for Proactive Cyber Threat Intelligence

Automated monitoring of dark web (DW) platforms on a large scale is the first step toward developing proactive Cyber Threat Intelligence (CTI). While there are efficient methods for collecting data from the surface web, large-scale dark web data collection is often hindered by anti-crawling measures. In particular, text-based CAPTCHA serves as the most prevalent and prohibiting type of these measures in the dark web. Text-based CAPTCHA identifies and blocks automated crawlers by forcing the user to enter a combination of hard-to-recognize alphanumeric characters. In the dark web, CAPTCHA images are meticulously designed with additional background noise and variable character length to prevent automated CAPTCHA breaking. Existing automated CAPTCHA breaking methods have difficulties in overcoming these dark web challenges. As such, solving dark web text-based CAPTCHA has been relying heavily on human involvement, which is labor-intensive and time-consuming. In this study, we propose a novel framework for automated breaking of dark web CAPTCHA to facilitate dark web data collection. This framework encompasses a novel generative method to recognize dark web text-based CAPTCHA with noisy background and variable character length. To eliminate the need for human involvement, the proposed framework utilizes Generative Adversarial Network (GAN) to counteract dark web background noise and leverages an enhanced character segmentation algorithm to handle CAPTCHA images with variable character length. Our proposed framework, DW-GAN, was systematically evaluated on multiple dark web CAPTCHA testbeds. DW-GAN significantly outperformed the state-of-the-art benchmark methods on all datasets, achieving over 94.4% success rate on a carefully collected real-world dark web dataset. We further conducted a case study on an emergent Dark Net Marketplace (DNM) to demonstrate that DW-GAN eliminated human involvement by automatically solving CAPTCHA challenges with no more than three attempts. Our research enables the CTI community to develop advanced, large-scale dark web monitoring. We make DW-GAN code available to the community as an open-source tool in GitHub.
