In discussing the limits of human knowledge, physical objects are, in principle, not identical to the apparent ones. This is because the latter depend also on the observer. Virtual reality (VR) models are environments that address the senses and therefore belong to the apparent space. Therefore, they seem to prevent an epistemic justification. Based on that, this paper discusses VR technology’s potential to provide knowledge of external reality to students. This is particularly important in light of the conditions imposed by the COVID-19 pandemic, which have led to an increasingly significant role of VR related technologies in education. The research question of this study is whether VR models being used as educational tools, bring us closer – or not – to knowing the properties of physical objects. The main focus of this epistemic investigation is Russell’s theory of perception with an emphasis to the concept of space. Analysis indicates that VR is educationally useful especially when it comes to objects that are absent from our perceptual range. VR technology brings us closer to the theoretical properties of non-perceptual objects, those that cannot be perceived by the senses, like exoplanets. Furthermore, it brings us closer to the non-perceptual properties of directly perceived objects, properties referring, for example to subatomic structures. In a theoretical level, this macro and micro “terra incognita” may be linked to the sensibilia entities proposed by Russell (1914).

Aristotelian leadership in corporations and organizations and the virtues associated with it has been extensively studied. Today, due to the pandemic but mainly because of Information Communication Technologies (ICT) and the Fourth Industrial Revolution, there is an increase in online communication within corporate organizations (via emails, teleconferencing, etc.). In this new context, managers, CEOs and company leaders are developing digital behaviors. Online and electronic communication has largely replaced in person and a leader or e-leader should cultivate and use her virtues within a new digital environment. In this context, can we refer to emerging “digital virtues” or is the technological factor too “weak” to disturb the nature of these character traits? In order to address this question, this paper investigates four Aristotelian virtues that lie at the heart of an ethical corporate leader, i.e. “prudence/practical wisdom”, “fortitude” (courage), “temperance”, and “justice”. The findings will determine whether changing the means of communication affects the way in which a leader should develop these virtues.

This paper investigates social advertising both in social media and mass media during the first lockdown of the Covid-19 pandemic in Greece. It presents a qualitative analysis of the advertisements that were part of the coronavirus campaigns “Stay at home” and “Stay safe”, from March to June 2020. The analysis is based on semiotic and communication models. The aim of the research is to find out to what extend those advertising spots shaped the new daily life of the citizens, acting either informatively or instructively. Findings indicate that the campaign adapted to the needs of an already tired public. Furthermore, those specific social ads neither did they meet the expectations, nor resulted as expected, reproducing mostly stereotypes. They eventually did not innovate, express better ideas nor effectively communicate the intended message without provoking, distracting from the central objective or raising debate for all the wrong reasons.

One of the instant increases in coaching and mentoring has been apparent in last years, indicating the improved interest in several development aspects. This development concerns all sectors of the economy and society, such as education, health, entrepreneurship. The focus was on actions to enhance efficiency through development, mainly for the labor sector. Mentoring and coaching are now integral parts of educational life and vocational training, with the ultimate goal of the multifaceted development of those employed in various professions. This article was written during the Covid-19 pandemic to study the impact of the pandemic on the digital age and coaching and mentoring processes. The research data have emerged from recent studies, with full knowledge of the prevailing situation, including all problems and uncertainties. As we face the immense business interruptions due to the Covid-19 pandemic, coaching and mentoring play a significant role in maintaining employees motivated and determined during extraordinary times.

The 4th Industrial Revolution, or 2nd digital revolution, has brought about drastic changes in the economy and society, as technology develops at a rapid pace. Digital humanities take advantage of this technological evolution to uncover new ways to approach the humanities and the social sciences. In particular, the 4IR has enabled the development of new technologies that are facilitating the integration of virtual and physical environments in different digital humanities sectors, such as arts and culture. In addition, it helped digital humanities scholars to analyse massive amounts of data and apply machine learning algorithms to identify patterns, uncover new insights and approach cultural, historical, and literary phenomena in a more comprehensive and differentiated way. In the context of 4IR, the Semantic Web plays a crucial role in enabling machines and humans to access and use the vast amount of data generated by advanced technologies, by providing a common language and structure for data exchange and integration.
