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
One Small Step for Generative AI, One Giant Leap for AGI: A Complete Survey on ChatGPT in AIGC Era
OpenAI has recently released GPT-4 (a.k.a. ChatGPT plus), which is
demonstrated to be one small step for generative AI (GAI), but one giant leap
for artificial general intelligence (AGI). Since its official release in
November 2022, ChatGPT has quickly attracted numerous users with extensive
media coverage. Such unprecedented attention has also motivated numerous
researchers to investigate ChatGPT from various aspects. According to Google
scholar, there are more than 500 articles with ChatGPT in their titles or
mentioning it in their abstracts. Considering this, a review is urgently
needed, and our work fills this gap. Overall, this work is the first to survey
ChatGPT with a comprehensive review of its underlying technology, applications,
and challenges. Moreover, we present an outlook on how ChatGPT might evolve to
realize general-purpose AIGC (a.k.a. AI-generated content), which will be a
significant milestone for the development of AGI.Comment: A Survey on ChatGPT and GPT-4, 29 pages. Feedback is appreciated

The Effects of Tailored Energy Preservation Training on Fatigue and Re-admission in Patients with Heart Failure: A Randomized Clinical Trial
Background: Fatigue and re-admissions are the important consequences of heart failure that cause limitations in patients’ daily activities, personal, and social affairs. Energy conservation techniques are among evidence-based and non-pharmacological approaches that can reduce fatigue in patients with chronic disease.      Aim: The present study was performed with aim to determine the effects of tailored energy conservation training on fatigue and readmissions of patients with heart failure (HF).Method: This randomized clinical trial study was performed from May 2019 to March 2020 on 96 patients with HF admitted to CCU and cardiovascular clinics affiliated to Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran. Patients who met the inclusion criteria were randomly assigned to the intervention and control groups. A three-part tool (demographic-clinical questionnaire and need assessment), the Fatigue Severity Scale (FSS) and a readmissions record checklist were used to collect data. After determining the training needs of each individual, the intervention group received five 45-minute face-to-face individual training sessions of energy conservation strategies reinforced by telephone support every two weeks and followed up for 12 weeks. The control group only received routine post-discharge training. Fatigue scores by FSS and the readmissions recorded were tested at baseline and three months after the end of the intervention.Results: At baseline, the two groups were comparable in the mean hospital admissions and fatigue scores. However, after the intervention, the mean frequency of hospital admissions and the mean fatigue score were significantly lower in the intervention group (1.36±1.26, P< 0.001; 2.86±1.01,P< 0.001) than in the control group (0.42±0.77, P< 0.001; 5.25±1.03, P< 0.001) respectively.Implications for Practice: Nurses and physicians are recommended to teach energy conservation methods to patients with HF and chronic conditions who are prone to fatigue and its side effects
Economia colaborativa
A importância de se proceder à análise dos principais desafios jurÃdicos que a economia colaborativa coloca – pelas implicações que as mudanças de paradigma dos modelos de negócios e dos sujeitos envolvidos suscitam − é indiscutÃvel, correspondendo à necessidade de se fomentar a segurança jurÃdica destas práticas, potenciadoras de crescimento económico e bem-estar social.
O Centro de Investigação em Justiça e Governação (JusGov) constituiu uma equipa multidisciplinar que, além de juristas, integra investigadores de outras áreas, como a economia e a gestão, dos vários grupos do JusGov – embora com especial participação dos investigadores que integram o grupo E-TEC (Estado, Empresa e Tecnologia) – e de outras prestigiadas instituições nacionais e internacionais, para desenvolver um projeto neste domÃnio, com o objetivo de identificar os problemas jurÃdicos que a economia colaborativa suscita e avaliar se já existem soluções para aqueles, refletindo igualmente sobre a conveniência de serem introduzidas alterações ou se será mesmo necessário criar nova regulamentação.
O resultado desta investigação é apresentado nesta obra, com o que se pretende fomentar a continuação do debate sobre este tema.Esta obra é financiada por fundos nacionais através da FCT — Fundação para a Ciência e a Tecnologia, I.P., no âmbito do Financiamento UID/05749/202
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
Constructing a Theological Framework That Revitalizes the Missional Nature of Churches of Christ in South Australia
This thesis addresses the need for a theological framework that revitalizes the missional nature of Churches of Christ in South Australia. The problem identified within this ministry context was a lack of clear theological principles that informed a common understanding of identity for missional engagement. The purpose of the project was to create a study guide that informs common theological commitments and grounds congregations for missional vitality. A research and development team made up of seven Church of Christ ministers from different backgrounds was assembled to design a curriculum that addressed the problem. Through eight two-hour sessions over four months in the first half of 2022, the team discussed a theological framework that could revitalize mission. This was informed by a Trinitarian theological rationale introduced as perichoresis. The conceptual framework for discussions included (1) the historical and theological foundations of Churches of Christ, (2) a Trinitarian doctrine of God presented as perichoresis, (3) contemporary congregational practices, and (4) a theological proposal for re-imagining mission. The team developed a study guide that promotes a dynamic theological framework for practicing theology and revitalizing the missional nature of the church. The artifact, Movement & Identity: Participating in the Life of God’s Mission, was evaluated by the team and members of Church of Christ congregations in South Australia. The curriculum is designed to assist participants with practical theological interpretation through (1) discovering new ideas about God in the context of Churches of Christ traditions, (2) engaging with contextual theology in community, (3) participating in God’s mission, and (4) reflecting on how God’s agency transforms the church. The development of the study guide will stimulate a practical theological framework that promotes dynamic theological dialogue and missional vitality for Churches of Christ in South Australia
Higher Education’s Effect on Retention: Exploring the Experiences of CPS Caseworkers
This qualitative research study was an exploration of Child Protective Services (CPS) frontline caseworkers\u27 experiences. The problem investigated was the high number of caseworkers who lacked the knowledge and skills necessary to do their job and the constant turnover of workers within the agency. Although previous researchers have explored many factors that cause caseworker turnover, the research has not focused much on the caseworkers’ perspective. Therefore, this qualitative study explored CPS caseworkers’ opinions and experiences using virtual semistructured interviews. The study specifically focused on the impact that education and training has on job performance and turnover. The study population was CPS caseworkers who had worked in a large urban community in Texas for 2 years or more. The sample included eight caseworkers who had experienced the turnover firsthand. Thematic analysis of the transcripts of the audio-recorded interviews and data coding using NVivo software led to the development of a coding system to identify patterns and common themes. The findings indicated that for caseworkers, hands-on training, gaining experience, unity between caseworkers, social service training, and leadership support may lead to decreased turnover rates and increased job performance. Agency leaders and other professionals in the social service field may consider the findings to improve caseworker retention and organizational outcomes. These improvements could prompt positive change through leadership and policy adjustments designed to support the needs of CPS caseworkers related to education, training, and retention.

Queens of the Hill: How Title IX Fares in the Hilltop Neighborhood of Columbus, Ohio
National research indicates that Title IX of the Education Amendments of 1972 leaves Black girls behind in the pursuit of gender equity. Low rates of participation and high dropout rates in girls sports plague low-income, majority-minority high schools. This thesis investigates whether the national research holds true in Columbus, Ohio, specifically at West High School. Following from a series of interviews with coaches, teachers, and a student, I find that West High School’s athletic program is Title IX compliant, but girls at West High School still face severe barriers to sports participation. A school can comply with Title IX and fall short of equal opportunity for sports participation. Title IX leaves girls at West High School behind because it is reliant on a top-down approach of administrative punishment, threatening the loss of federal funding. To achieve authentic gender equity, West High School and other low-income, majority-minority schools must supplement Title IX with a bottom-up approach that is community and culturally centered
Message Journal, Issue 5: COVID-19 SPECIAL ISSUE Capturing visual insights, thoughts and reflections on 2020/21 and beyond...
If there is a theme running through the Message Covid-19 special issue, it is one of caring. Of our own and others’ resilience and wellbeing, of friendship and community, of students, practitioners and their futures, of social justice, equality and of doing the right thing. The veins of designing with care run through the edition, wide and deep. It captures, not designers as heroes, but those with humble views, exposing the need to understand a diversity of perspectives when trying to comprehend the complexity that Covid-19 continues to generate.
As graphic designers, illustrators and visual communicators, contributors have created, documented, written, visualised, reflected, shared, connected and co-created, designed for good causes and re-defined what it is to be a student, an academic and a designer during the pandemic. This poignant period in time has driven us, through isolation, towards new rules of living, and new ways of working; to see and map the world in a different light. A light that is uncertain, disjointed, and constantly being redefined.
This Message issue captures responses from the graphic communication design community in their raw state, to allow contributors to communicate their experiences through both their written and visual voice. Thus, the reader can discern as much from the words as the design and visualisations.
Through this issue a substantial number of contributions have focused on personal reflection, isolation, fear, anxiety and wellbeing, as well as reaching out to community, making connections and collaborating. This was not surprising in a world in which connection with others has often been remote, and where ‘normal’ social structures of support and care have been broken down. We also gain insight into those who are using graphic communication design to inspire and capture new ways of teaching and learning, developing themselves as designers, educators, and activists, responding to social justice and to do good; gaining greater insight into society, government actions and conspiracy.
