The Metaverse: Survey, Trends, Novel Pipeline Ecosystem & Future Directions
The Metaverse offers a second world beyond reality, where boundaries are
non-existent, and possibilities are endless through engagement and immersive
experiences using the virtual reality (VR) technology. Many disciplines can
benefit from the advancement of the Metaverse when accurately developed,
including the fields of technology, gaming, education, art, and culture.
Nevertheless, developing the Metaverse environment to its full potential is an
ambiguous task that needs proper guidance and directions. Existing surveys on
the Metaverse focus only on a specific aspect and discipline of the Metaverse
and lack a holistic view of the entire process. To this end, a more holistic,
multi-disciplinary, in-depth, and academic and industry-oriented review is
required to provide a thorough study of the Metaverse development pipeline. To
address these issues, we present in this survey a novel multi-layered pipeline
ecosystem composed of (1) the Metaverse computing, networking, communications
and hardware infrastructure, (2) environment digitization, and (3) user
interactions. For every layer, we discuss the components that detail the steps
of its development. Also, for each of these components, we examine the impact
of a set of enabling technologies and empowering domains (e.g., Artificial
Intelligence, Security & Privacy, Blockchain, Business, Ethics, and Social) on
its advancement. In addition, we explain the importance of these technologies
to support decentralization, interoperability, user experiences, interactions,
and monetization. Our presented study highlights the existing challenges for
each component, followed by research directions and potential solutions. To the
best of our knowledge, this survey is the most comprehensive and allows users,
scholars, and entrepreneurs to get an in-depth understanding of the Metaverse
ecosystem to find their opportunities and potentials for contribution

A Design Science Research Approach to Smart and Collaborative Urban Supply Networks
Urban supply networks are facing increasing demands and challenges and thus constitute a relevant field for research and practical development. Supply chain management holds enormous potential and relevance for society and everyday life as the flow of goods and information are important economic functions. Being a heterogeneous field, the literature base of supply chain management research is difficult to manage and navigate. Disruptive digital technologies and the implementation of cross-network information analysis and sharing drive the need for new organisational and technological approaches. Practical issues are manifold and include mega trends such as digital transformation, urbanisation, and environmental awareness.
A promising approach to solving these problems is the realisation of smart and collaborative supply networks. The growth of artificial intelligence applications in recent years has led to a wide range of applications in a variety of domains. However, the potential of artificial intelligence utilisation in supply chain management has not yet been fully exploited. Similarly, value creation increasingly takes place in networked value creation cycles that have become continuously more collaborative, complex, and dynamic as interactions in business processes involving information technologies have become more intense.
Following a design science research approach this cumulative thesis comprises the development and discussion of four artefacts for the analysis and advancement of smart and collaborative urban supply networks. This thesis aims to highlight the potential of artificial intelligence-based supply networks, to advance data-driven inter-organisational collaboration, and to improve last mile supply network sustainability. Based on thorough machine learning and systematic literature reviews, reference and system dynamics modelling, simulation, and qualitative empirical research, the artefacts provide a valuable contribution to research and practice
Investigating process skills and competency gaps in undergraduate agricultural extension curriculum in selected South African universities
The Michigan State University Alliance for African Partnership (AAP) launched a multi-country study to contribute to upgrading and tailoring the agricultural extension curricula at participating institutions. The first phase of primary data collection consisted of focus group discussions. The focus groups were structured around a specific objective: gathering information around specific questions. Focus group discussions were followed by an online survey of Agricultural Extension and Advisory Services (AEAS) role players, of which the results will be discussed separately. It was concluded from the focus group discussions that the AEAS workers in South Africa lacked the critical skills to perform their responsibilities efficiently. Several required skills were singled out during the focus group discussions. It was concluded that it is vital for agricultural development in the country to ensure that these skills and competencies are included in all South African teaching institutions' curricula. It is therefore recommended that it is critical for each institution offering agricultural extension training to keep the curriculum relevant so that it meets the needs of the profession. Keeping the curriculum relevant includes participatory curriculum development (PCD), regular review of the curriculum by all the stakeholders of the profession, and the necessary collaborations with professional bodies to regulate the curriculum. The efficiency in the sector will be enhanced if AEAS qualifications at the various training institutions cater to the profession's demands
Subsidiary Entrepreneurial Alertness: Antecedents and Outcomes
This thesis brings together concepts from both international business and entrepreneurship to develop a framework of the facilitators of subsidiary innovation and performance. This study proposes that Subsidiary Entrepreneurial Alertness (SEA) facilitates the recognition of opportunities (the origin of subsidiary initiatives). First introduced by Kirzner (1979) in the context of the individual, entrepreneurial alertness (EA) is the ability to notice an opportunity without actively searching. Similarly, to entrepreneurial alertness at the individual level, this study argues that SEA enables the subsidiary to best select opportunities based on resources available. The research further develops our conceptualisation of SEA by drawing on work by Tang et al. (2012) identifying three distinct activities of EA: scanning and search (identifying opportunities unseen by others due to their awareness gaps), association and connection of information, and evaluation and judgement to interpret or anticipate future viability of opportunities. This study then hypothesises that SEA leads to opportunity recognition at the subsidiary level and further hypothesises innovation and performance as outcomes of opportunity recognition. This research brings these arguments together to develop and test a comprehensive theoretical model.
The theoretical model is tested through a mail survey of the CEOs/MDs of foreign subsidiaries within the Republic of Ireland (an innovative hub for foreign subsidiaries). This method was selected as the best method to reach the targeted respondent, and due to the depth of knowledge the target respondent holds, the survey can answer the desired question more substantially. The results were examined using partial least squares structural equation modelling (PLS-SEM). The study’s findings confirm two critical aspects of subsidiary context, subsidiary brokerage and subsidiary credibility are positively related to SEA. The study establishes a positive link between SEA and both the generation of innovation and the subsidiary’s performance. This thesis makes three significant contributions to the subsidiary literature as it 1) introduces and develops the concept of SEA, 2) identifies the antecedents of SEA, and 3) demonstrates the impact of SEA on subsidiary opportunity recognition. Implications for subsidiaries, headquarters and policy makers are discussed along with the limitations of the study
Consent and the Construction of the Volunteer: Institutional Settings of Experimental Research on Human Beings in Britain during the Cold War
This study challenges the primacy of consent in the history of human experimentation and argues that privileging the cultural frameworks adds nuance to our understanding of the construction of the volunteer in the period 1945 to 1970. Historians and bio-ethicists have argued that medical ethics codes have marked out the parameters of using people as subjects in medical scientific research and that the consent of the subjects was fundamental to their status as volunteers. However, the temporality of the creation of medical ethics codes means that they need to be understood within their historical context. That medical ethics codes arose from a specific historical context rather than a concerted and conscious determination to safeguard the well-being of subjects needs to be acknowledged. The British context of human experimentation is under-researched and there has been even less focus on the cultural frameworks within which experiments took place. This study demonstrates, through a close analysis of the Medical Research Council's Common Cold Research Unit (CCRU) and the government's military research facility, the Chemical Defence Experimental Establishment, Porton Down (Porton), that the `volunteer' in human experiments was a subjective entity whose identity was specific to the institution which recruited and made use of the subject. By examining representations of volunteers in the British press, the rhetoric of the government's collectivist agenda becomes evident and this fed into the institutional construction of the volunteer at the CCRU. In contrast, discussions between Porton scientists, staff members, and government officials demonstrate that the use of military personnel in secret chemical warfare experiments was far more complex. Conflicting interests of the military, the government and the scientific imperative affected how the military volunteer was perceived
The Gradual Disappearance Of Financial Literacy In Today\u27s World. What Is Financial Literacy And Why Is It So Important? My Own Story Of Acquisition
There is a growing concern in this country that the middle class is disappearing and not in the way one would hope. Instead of families moving into a higher socio-economic class and being able to provide richer life experiences for themselves and their children, vast numbers are shifting to a lower socio-economic status level. The gap between the affluent and those barely eking out an existence is increasing at an alarming rate. This trend will directly affect who can successfully attend college and who will be available and capable to perform the blue-collar jobs that are vital to the continuation of our economy. Many of these jobs are becoming increasingly complex and sophisticated. While they may not require a college degree, they do require additional post-secondary training and expertise. Longer reaching concerns are that a dwindling middle class equates to a smaller tax base and contributes to a larger segment of the population that needs financial assistance.
The productive management of money is part of a concept known as financial literacy. People that have money take this knowledge for granted. Somewhere along the line, whether it was at home, in school, or from personal experiences, successful people learned the value of earning money and using it thoughtfully and intentionally in order to achieve a future goal. No one disputes the fact that personal choices and discretion are parts of the picture.
Imagine, however, that the environment in which you grew up did not contain earning possibilities. Perhaps you had to work without pay caring for your siblings, leaving no time to go out and earn your own money. Maybe your family was in the situation where everything that each family member earned was required to try to make ends meet. The result can be a feeling of ignorance and powerlessness around financial literacy and a lack of understanding the difference it could make in your life.
This dissertation examines these issues. As a Scholarly Personal Narrative, it will also relate the story of my own journey of acquiring financial literacy and how that knowledge has affected my life. It concludes with a proposal that I created for teaching the concepts of financial literacy to underserved members of our society living at the lower socio-economic level. This education is important because understanding financial literacy can build self-confidence, empowerment, and purpose. This knowledge can also set an example that parents can pass on to their children and future generations. I believe this is one possible route toward breaking the cycle of poverty
