Social organisations and their entrepreneurial approaches are quite challenging to avail a robust and sustainable platform. Yet it is more difficult when the venture is aimed to serve an uncommon service that the target group are not aware of. Leveraging morale boosts and power of the mind through yoga and transcendental meditation practices could be an approach of a social enterprise that are outlined in this chapter. How tranquility and mental peace in the midst a huge number of people can be achieved by some innovative steps, that is also conferred here.

Plastic has been a very useful material which is very cheap, easy to carry and is resilient to biodegradation. That is why plastic has been used, sometimes reused, and overused due to the reasons mentioned above. As a result, landfills and oceans are full of plastic. But if we consider all the negative health effects, environmental / ecological effects it has in present times, we can understand that it is environmentally very expensive to use plastic. Bangladesh is a relatively young country with dense population and limited resource. Proper management of plastic remains an issue with the country. Considering these, this chapter focuses on how plastic is used, how it is treated as waste and what can be possible solutions in reducing the amount of plastic in Bangladesh.

The involvement of wear, friction and lubrication in engineering systems and industrial applications makes it imperative to study the various aspects of tribology in relation with advanced technologies and concepts. The concept of Industry 4.0 and its implementation further faces a lot of barriers, particularly in developing economies. Real-time and reliable data is an important enabler for the implementation of the concept of Industry 4.0. For availability of reliable and real-time data about various tribological systems is crucial in applying the various concepts of Industry 4.0. This paper aims to attempt to highlight the role of sensors related to friction, wear and lubrication in implementing Industry 4.0 in various tribology-related industries and equipment.

A through literature review has been done to study the interrelationships between the availability of tribology-related data and implementation of Industry 4.0 are also discussed. Relevant and recent research papers from prominent databases have been included. A detailed overview about the various types of sensors used in generating tribological data is also presented. Some studies related to the application of machine learning and artificial intelligence (AI) are also included in the paper. A discussion on fault diagnosis and cyber physical systems in connection with tribology has also been included.

Industry 4.0 and tribology are interconnected through various means and the various pillars of Industry 4.0 such as big data, AI can effectively be implemented in various tribological systems. Data is an important parameter in the effective application of concepts of Industry 4.0 in the tribological environment. Sensors have a vital role to play in the implementation of Industry 4.0 in tribological systems. Determining the machine health, carrying out maintenance in off-shore and remote mechanical systems is possible by applying online-real-time data acquisition.

The paper tries to relate the pillars of Industry 4.0 with various aspects of tribology. The paper is a first of its kind wherein the interdisciplinary field of tribology has been linked with Industry 4.0. The paper also highlights the role of sensors in generating tribological data related to the critical parameters, such as wear rate, coefficient of friction, surface roughness which is critical in implementing the various pillars of Industry 4.0.

This study employs bibliometric analysis to map the research landscape of social media trending topics during the COVID-19 pandemic. The authors aim to offer a comprehensive review of the predominant research organisations and countries, key themes and favoured research methodologies pertinent to this subject.

The authors extracted data on social media trending topics from the Web of Science Core Collection database, spanning from 2009 to 2022. A total of 1,504 publications were subjected to bibliometric analysis, utilising the VOSviewer tool. The study analytical process encompassed co-occurrence, co-authorship, citation analysis, field mapping, bibliographic coupling and co-citation analysis.

Interest in social media research, particularly on trending topics during the COVID-19 pandemic, remains high despite signs of the pandemic stabilising globally. The study predominantly addresses misinformation and public health communication, with notable focus on interactions between governments and the public. Recent studies have concentrated on analysing Twitter user data through text mining, sentiment analysis and topic modelling. The authors also identify key leading organisations, countries and journals that are central to this research area.

Diverging from the narrow focus of previous literature reviews on social media, which are often confined to particular fields or sectors, this study offers a broad view of social media's role, emphasising trending topics. The authors demonstrate a significant link between social media trends and public events, such as the COVID-19 pandemic. The paper discusses research priorities that emerged during the pandemic and outlines potential methodologies for future studies, advocating for a greater emphasis on qualitative approaches.

The COVID-19 pandemic, in addition to posing challenges, has also created opportunities for greater digital integration than ever. However, the scale and efficacy of digital integration are contingent on the digital competence (DC) of teachers. In the same way, how well teachers learn and teach online may depend on how willing they are to try new ways of digitizing learning or being innovative. This study aimed to ascertain if teachers' digital nativeness, digital addiction and innovative work behavior had an impact on their DC.

The study used a quantitative research method, whereby data were collected from 276 schools, colleges and university teachers. The researchers employed structural equation modeling (SEM) using SmartPLS to analyze the data.

The results illuminate the literature regarding DC and the predictive capability of teachers' digital nativeness, digital addiction and innovative work behavior, which can contribute to paving the way for digitizing teaching and learning in the post-COVID-19 era.

The study has significant implications for meaningful learner engagement by explaining the importance of teachers' digital competencies and how they could be approached conceptually to better understand the factors associated with teachers' DC. The differences in DC between digital natives and digital emigrants remain one of the limitations that future research may address.

The results have policy level and practical implications for organizations to consider the value of young teachers in the integration of digital resources. It is also critical to encourage teachers' innovative behavior in the digitization of teaching by creating a supportive organizational environment.

The study remains valuable in the post-COVID-19 era, where educational institutes are revisiting the prospect of online learning as a parallel to in-person teaching. The results remain innovative and genuine and have not been explored in previous research, in particular in the post-COVID-19 era. The involvement of teachers from schools, colleges and universities makes the results more general, which all of them can equally benefit from.
