    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

    Deep Transfer Learning Applications in Intrusion Detection Systems: A Comprehensive Review

    Full text link
    Globally, the external Internet is increasingly being connected to the contemporary industrial control system. As a result, there is an immediate need to protect the network from several threats. The key infrastructure of industrial activity may be protected from harm by using an intrusion detection system (IDS), a preventive measure mechanism, to recognize new kinds of dangerous threats and hostile activities. The most recent artificial intelligence (AI) techniques used to create IDS in many kinds of industrial control networks are examined in this study, with a particular emphasis on IDS-based deep transfer learning (DTL). This latter can be seen as a type of information fusion that merge, and/or adapt knowledge from multiple domains to enhance the performance of the target task, particularly when the labeled data in the target domain is scarce. Publications issued after 2015 were taken into account. These selected publications were divided into three categories: DTL-only and IDS-only are involved in the introduction and background, and DTL-based IDS papers are involved in the core papers of this review. Researchers will be able to have a better grasp of the current state of DTL approaches used in IDS in many different types of networks by reading this review paper. Other useful information, such as the datasets used, the sort of DTL employed, the pre-trained network, IDS techniques, the evaluation metrics including accuracy/F-score and false alarm rate (FAR), and the improvement gained, were also covered. The algorithms, and methods used in several studies, or illustrate deeply and clearly the principle in any DTL-based IDS subcategory are presented to the reader

    The media is constructed and interpreted through what people 'know'. That knowledge is, forthe most part, created through day to day experiences. In Pakistan, Islam and nationalism aretwo components of this social knowledge which are intrinsically tied to the experiences of thePakistani people. Censorship and selection are means through which this knowledge isarticulated and interpreted.General conceptions of partially shared large scale bodies of knowledge and ideas reinforce,and are reinforced by, general medium of mass communication: the print and electronic media.Focusing on the govermnent, media institutions and Pakistani elites, I describe and analyse thedifferent, sometimes conflicting, interpretations of Islam and Pakistani nationalism manifest inand through media productions presented in Pakistan.The media means many things, not least of which is power. It is the media as a source ofpower that is so frequently controlled, directed and manipulated. The terminology may beslightly different according to the context within which one is talking - propaganda, selection,etc. - but ultimately it comes down to the same thing - censorship. Each of the three groups:government, media institutions and Pakistani elites - have the power to interpret and censormedia content and consideration must be taken of each of the other power holders consequentlyrestricting the power of each group in relation to the other two. The processes of thismanipulation and their consequences form the major themes of this thesis

    Chinese Benteng Women’s Participation in Local Development Affairs in Indonesia: Appropriate means for struggle and a pathway to claim citizen’ right?

    It had been more than two decades passing by aftermath the devastating Asia’s Financial Crisis in 1997, subsequently followed by Suharto’s step down from his presidential throne which he occupied for more than three decades. The financial turmoil turned to a political disaster furthermore has led to massive looting that severely impacted Indonesians of Chinese descendant, including unresolved mystery of the most atrocious sexual violation against women and covert killings of students and democracy activists in this country. Since then, precisely aftermath May 1998, which publicly known as “Reformasi”1, Indonesia underwent political reform that eventually corresponded positively to its macroeconomic growth. Twenty years later, in 2018, Indonesia captured worldwide attention because it has successfully hosted two internationally renowned events, namely the Asian Games 2018 – the most prestigious sport events in Asia – conducted in Jakarta and Palembang; and the IMF/World Bank Annual Meeting 2018 in Bali. Particularly in the IMF/World Bank Annual Meeting, this event has significantly elevated Indonesia’s credibility and international prestige in the global economic powerplay as one of the nations with promising growth and openness. However, the narrative about poverty and inequality, including increasing racial tension, religious conservatism, and sexual violation against women are superseded by friendly climate for foreign investment and eventually excessive glorification of the nation’s economic growth. By portraying the image of promising new economic power, as rhetorically promised by President Joko Widodo during his presidential terms, Indonesia has swept the growing inequality in this highly stratified society that historically compounded with religious and racial tension under the carpet of digital economy.Arte y Humanidade

    Masculinities, vulnerability and negotiated identity: Understanding the reporting behaviours of men who experience violence or otherwise harmful behaviour, within a sex work context

    Context The focus of sex work related discussions most commonly falls on female providers of sexual services, and male purchasers. As a result, the often victim-oriented policy response in England and Wales falls short of truly addressing the needs of men who are involved in the sale of sex, with there being limited support available for them and a systemic approach which does not fully recognise the potential for men to face harm within this context. Methods The aim of this study is to explore experiences of and reactions to violence, and otherwise harmful behaviours, faced by men in the context of their sex working, by understanding the lived realities of a sample of men who engage in this type of work. The study takes a phased approach which combines an initial informative quantitative survey, with three subsequent phases of semi-structured interviews with male sex workers, sex work-focused practitioners and police officers. The method is guided by feminist research principles which suggest that reality is situated within those with lived experience, and also by an element of co-creation which has grounded this study within the perspectives of male sex workers from its conception. Findings The findings of this research suggest that all of the men involved in the study had faced at least one of the violent or otherwise harmful behaviours outlined, though reporting of these behaviours was not at all common. Discussions with the male sex working participants, practitioners and the police highlighted the issues related to the structural influences of authority, such as the police, and the social environment, and the internalisation of these wider factors, which create barriers to reporting for groups such as male sex workers and others who face similar social marginalisation. Conclusions This study challenges existing gendered understandings of violence and otherwise harmful behaviour within a sex work context, by highlighting the harmful experiences of men. By exploring these experiences and the reporting behaviours of those involved, the study also proposes a new framework for understanding barriers to reporting, which suggests that these are formed through the influences of formal and informal measures of social control, and the internalisation of these outside influences by the individual. By better understanding the experiences of men, and the barriers to their reporting, this study attempts to nuance a gendered discussion. Within, I propose that in order to better support male sex workers, responses must begin by appreciating the heterogeneity of those involved in sex work and the influence of their individual circumstances and the social environment on their willingness to seek support

    B/order work: recomposing relations in the seamful carescapes of health and social care integration in Scotland

    As people, ageing and living with disabilities, struggle with how care is enacted through their lives, integrated care has gained policy purchase in many places, especially in the United Kingdom. Accordingly, there have been various (re)forms of care configurations instigated, in particular, promoting partnership and service redesign. Despite integrations apparent popularity, its contribution to improved service delivery and outcomes for people has been questioned, exposing ongoing uncertainties about what it entails and its associated benefits. Nonetheless, over decades, a remarkably consistent approach to integrated care has advanced collaboration as a solution. Equally, any (re)configurations emerge through wider infrastructures of care, in what might be regarded as dis-integrated care, as complex carescapes attempt to hold and aporias remain. In 2014, the Scottish Public Bodies (Joint Working) (Scotland) Act mandated Health and Social Care Integration (HSCI), as a means to mend fraying carescapes; a flagship policy epitomising public service reform in Scotland, in which normative aspirations of collaboration are central. What then are the accomplishments of this ambitious legislation? From the vantage point of 2021, HSCI has been assessed as slow and insubstantial, but this is not the complete picture. Narratives about failing to meet expectations obscure more complicated histories of cooperation and discord, successes and failures, and unintended consequences. Yet given collaborative ubiquity, if partnerships are contested how then are they practiced? To answer this question, I embarked on an interorganisational ethnography of the enactment of a Health and Social Care Partnership (HSCP), which went ‘live’ on April 1st, 2016; in a place I call ‘Kintra’. I interrogate what happened when several managers (from the NHS and Council) endeavoured to implement HSCI according to the precepts of the Act; working to both (re)configure and hold things together behind care frontiers; away from the bodywork of direct care, immersed in everyday arrangements in the spaces of governance and operations. I chart their efforts to comply with regulations, plan, and build governance apparatuses through documents. I explore through coalescent objects how distributed forms of governance, entwined in policy implementation, were subsequently both sustained, and challenged. I observed for seven months actors struggling to (re)configure care services embedded in a collaborative approach, as well as establish the legitimacy of the HSCP; exemplified through the fabrication of what was understood as a 'must-do' commissioning plan. In tracing documents, I show the ways in which HSCI was simultaneously materialised and constituted through documentation. I reveal how, in the mundane mattering of document manufacturing, possibilities for (re)forming the carescape emerged. By delving into inconspicuous, ‘seamful’ b/order work that both sustained distinctions between the NHS and Council and enabled b/order crossings, I expose how actors were knotted, and how this shaped efforts to recompose the contours of the carescape. While ‘Kintra’s story might be familiar, situated in concerns that may resonate across Scotland; I reveal how collaboration-as-practice is tangled in differing organisational practices, emerging from quotidian intra-actions in meeting rooms, offices, car parks and kitchenettes. I deploy a posthuman practice stance to show not only the way in which public administration ‘does’ care, but it’s world-making through a sociomaterial politics of anticipation. I was told legislation was the only way to make HSCI in ‘Kintra’ happen, nevertheless, there was resistance to limit the breadth and depth of integrating. Consequently, I show how the (re)organising of b/orders was an always-ongoing act of maintenance and repair of a (dis)integrating carescape; as I learnt at the end of my fieldwork, ‘it’s ‘Kintra, ‘it’s aye been!

    ‘We the People: Supporting Food SMEs towards a Circular Food Economy’

    This single Case Study locates SME (small and medium-size enterprise) hospitality and food services (HaFS) within a complex food waste system. It examines collaborative support for business change from linear resource wastage (‘take, use, dump), towards a circular food economy (CfE)- where ‘designing out’ food waste may reap savings. The objective is to support SME uptake of waste aversion practices so that they may thrive. The qualitative research centers on a London-based project promoting food waste valorization and healthy nutrition, in 15 boroughs. That project’s outreach for broad-based, collective impact included HaFS that are SMEs. Cross-sector liaison was the research focus for this Case Study which utilizes a hybrid philosophy and meta-framework, based on Critical Realism and Systemic Thinking. Some reference to Interpretivism highlights stewardship values for transforming individual behaviour. The Study also uses a multi-method design, borrowing soft systems from Management Science and Operational Research. Its blended approach includes: participant observation, mapping and rich picture techniques, semi-structured interviews and focus groups. The main research questions align concepts such as: circular economy, cross-sector collaboration and food waste management- with HaFS that are SMEs. A framework method and Leximancer software supported coding and qualitative thematic analysis. Primary findings include interesting categories of analytical, NGO and policy literature. Although conversations flagged up pivotal roles for our health and education sectors, the food SME element still seems peripheral in this transition to regenerative business. A ‘people vibe’ is enabling some HaFS’ kitchen waste action and food redistribution and, academia is a potential contributor to this information resource flow among stakeholders. The Study’s unique onto-epistemological framework enhances philosophical and theoretical knowledge about promoting SME resource stewardship. It spans Systemic Thinking (overt connections and acute complexities) and Critical Realism (deep mechanisms and institutional power differentials, impacting change). As an interpretive lens, the framework’s contribution to praxis was tested by shadowing the London TRiFOCAL project. This research could inform a business policy shift from traditional supply chain thinking, towards active UK food citizenship

    Knowledge Transfer for and through the Replication of Organisational Routines in Franchise Systems

    Get PDF
    Routines are dispositions to behave according to established sets of rules that are also repositories of the organisational memory about “how things get done”. Franchise systems are organisational forms which expand through the replication of routines by new units owned by franchisees. Drawing on insights from the literatures on organisational learning, organisational evolution (under generalised Darwinism), and cognitive psychology, this thesis identifies the building blocks for a conceptual explanation of routine replication in franchise systems. It then proposes an original case study of Yázigi, a large Brazilian franchise system of language schools, which is used to develop a novel process model that captures how knowledge is transferred for and through the replication of routines within an expanding franchise system. Four principal lessons are derived. First, when direct knowledge transfer is not available, artefacts, most notably template representations of routines, are essential. Second, intermediaries, as agents of routine compilation who direct participants to template representations, are crucial to the process of routine replication. Third, just as routines are analogues of habits, routine compilation seems to reproduce habit compilation. Finally, existing learning-related habits of thought may work in favour of or against the adoption of new habits in the replication process. This thesis outlines the prescriptive implications of these lessons for franchise practitioners and details opportunities for future research
