âTaking an Interdisciplinary Approach to Designing the Theoretical Part of a Level 5 Initial Teacher Education Programme Based on the âTriple Professionalismâ Concept, for Adult Community Learning Teachers in Essexâ
The Lingfield report (DBIS 2012) recommended that post-compulsory sector (PCS) institutions become business-oriented and revoked the statutory obligation for teachers to hold Level 5 (L5) teaching qualifications. As a result, the PCS, including my setting, Essex Adult Community Learning (EACL), has gone through unprecedented reforms.
EACL offers adults recreational and career-enhancing education. EACLâs inherent complexity has challenged its teachersâ professional identity as most became teachers whilst or after pursuing another career, work on an âas and whenâ basis and are not L5 teacher-trained. Practice demands have increased in response to local government and EACL restructures which gave EACL a significant role in delivering community development policy.
My qualitative research project explores the views of EACL teachers and managers, an adult education expert, a leading adult community learning policy figure and one of the authors of Triple Professionalism (TP) which is a professionalism model which adds to dual professionalism the knowledges/skills needed for working interdependently with other community stakeholders. The research draws together reported elements of EACL teachersâ professionalism and examines the professional knowledges/skills required of the teachersâ new spheres of operation. It explores TPâs potential for supporting EACL teachersâ professional identity and informing three new centre-devised modules to be incorporated in the Education and Training Foundationâs L5 Diploma in Education and Training (DET). The research concludes with proposing the structure of an EACL-specific TP-DET and recommending the content of the centre-devised modules.
The resulting TP-DET borrows from interdisciplinary methodologies because it is combining traditional teacher-training curriculum elements with knowledges/skills borrowed from unrelated-to-teaching fields, in particular, Learning Technology, Community Development and Business Management. Its delivery approach is also interdisciplinary because the field-expert lecturers join teacher-trainers in equipping trainees for classroom teaching whilst enabling them to understand and contribute to EACLâs managerial processes and business expansion and affirm their functionality as community workers. Current professional initial teacher education programmes do not afford the latter; the TP-DET, does
Survey on 6G Frontiers: Trends, Applications, Requirements, Technologies and Future Research
Emerging applications such as Internet of Everything, Holographic Telepresence, collaborative robots, and space and deep-sea tourism are already highlighting the limitations of existing fifth-generation (5G) mobile networks. These limitations are in terms of data-rate, latency, reliability, availability, processing, connection density and global coverage, spanning over ground, underwater and space. The sixth-generation (6G) of mobile networks are expected to burgeon in the coming decade to address these limitations. The development of 6G vision, applications, technologies and standards has already become a popular research theme in academia and the industry. In this paper, we provide a comprehensive survey of the current developments towards 6G. We highlight the societal and technological trends that initiate the drive towards 6G. Emerging applications to realize the demands raised by 6G driving trends are discussed subsequently. We also elaborate the requirements that are necessary to realize the 6G applications. Then we present the key enabling technologies in detail. We also outline current research projects and activities including standardization efforts towards the development of 6G. Finally, we summarize lessons learned from state-of-the-art research and discuss technical challenges that would shed a new light on future research directions towards 6G
Towards Time-Aware Context-Aware Deep Trust Prediction in Online Social Networks
Trust can be defined as a measure to determine which source of information is
reliable and with whom we should share or from whom we should accept
information. There are several applications for trust in Online Social Networks
(OSNs), including social spammer detection, fake news detection, retweet
behaviour detection and recommender systems. Trust prediction is the process of
predicting a new trust relation between two users who are not currently
connected. In applications of trust, trust relations among users need to be
predicted. This process faces many challenges, such as the sparsity of
user-specified trust relations, the context-awareness of trust and changes in
trust values over time. In this dissertation, we analyse the state-of-the-art
in pair-wise trust prediction models in OSNs. We discuss three main challenges
in this domain and present novel trust prediction approaches to address them.
We first focus on proposing a low-rank representation of users that
incorporates users' personality traits as additional information. Then, we
propose a set of context-aware trust prediction models. Finally, by considering
the time-dependency of trust relations, we propose a dynamic deep trust
prediction approach. We design and implement five pair-wise trust prediction
approaches and evaluate them with real-world datasets collected from OSNs. The
experimental results demonstrate the effectiveness of our approaches compared
to other state-of-the-art pair-wise trust prediction models.Comment: 158 pages, 20 figures, and 19 tables. This is my PhD thesis in

New Waves of IoT Technologies Research â Transcending Intelligence and Senses at the Edge to Create Multi Experience Environments
The next wave of Internet of Things (IoT) and Industrial Internet of Things (IIoT) brings new technological developments that incorporate radical advances in Artificial Intelligence (AI), edge computing processing, new sensing capabilities, more security protection and autonomous functions accelerating progress towards the ability for IoT systems to self-develop, self-maintain and self-optimise. The emergence of hyper autonomous IoT applications with enhanced sensing, distributed intelligence, edge processing and connectivity, combined with human augmentation, has the potential to power the transformation and optimisation of industrial sectors and to change the innovation landscape. This chapter is reviewing the most recent advances in the next wave of the IoT by looking not only at the technology enabling the IoT but also at the platforms and smart data aspects that will bring intelligence, sustainability, dependability, autonomy, and will support human-centric solutions.acceptedVersio
The Successes and Limitations of Retraining Non-specialist Teachers to Teach Mathematics
Acknowledging that there are simply too few mathematics teachers, the UK government is investing significantly in retraining programmes to equip non-specialist teachers to teach mathematics. With the new more mathematically rigorous GCSE courses, and the expectation that most post-16 students will engage with some mathematics (studying for A and AS levels, a Core Maths qualification or re-taking GCSE) many more teachers of mathematics will be needed. The questions posed, explore whether retraining could provide an effective way for alleviating the problem of the lack of well qualified teachers for mathematics. This thesis reports on the unfolding stories of eight teachers, from the 2013-2014 cohort, retrained by way of the Plymouth University model with me as course tutor. In this four-year longitudinal study, the teachers were followed during their year of retraining and in the succeeding years. A methodological model is proposed, for conducting intrusive and intimate research, with the researcher at the heart of the study; this is largely based on grounded theory with a constant comparative approach linking data with data, and data with literature. Interviews and lesson observations provided the mainstays for data collection, and summary narratives for each teacher were weaved from the multifarious sources of data. The analysis of the data leads to a set of propositions suggested for the implementation of future retraining programmes
Towards Tactile Internet in Beyond 5G Era: Recent Advances, Current Issues and Future Directions
Tactile Internet (TI) is envisioned to create a paradigm shift from the content-oriented
communications to steer/control-based communications by enabling real-time transmission of haptic information (i.e., touch, actuation, motion, vibration, surface texture) over Internet in addition to the conventional audiovisual and data traffics. This emerging TI technology, also considered as the next evolution phase of Internet of Things (IoT), is expected to create numerous opportunities for technology markets in a wide variety of applications ranging from teleoperation systems and Augmented/Virtual Reality (AR/VR) to automotive safety and eHealthcare towards addressing the complex problems of human society. However, the realization of TI over wireless media in the upcoming Fifth Generation (5G) and beyond networks creates various non-conventional communication challenges and stringent requirements
in terms of ultra-low latency, ultra-high reliability, high data-rate connectivity, resource allocation, multiple access and quality-latency-rate tradeoff. To this end, this paper aims to provide a holistic view on wireless TI along with a thorough review of the existing state-of-the-art, to identify and analyze the involved technical issues, to highlight potential solutions and to propose future research directions. First, starting with the vision of TI and recent advances and a review of related survey/overview articles, we present a generalized framework for wireless TI in the Beyond 5G Era including a TI architecture, the main technical requirements, the key application areas and potential enabling technologies. Subsequently, we provide a comprehensive review of the existing TI works by broadly categorizing them into three main paradigms; namely, haptic communications, wireless AR/VR, and autonomous, intelligent and cooperative mobility systems. Next, potential enabling technologies across physical/Medium Access Control (MAC) and network layers are identified and discussed in detail. Also, security and privacy issues of TI applications are discussed
along with some promising enablers. Finally, we present some open research challenges and recommend promising future research directions

Britain and the Occupation of Germany, 1945-49
The Allied Occupation of Germany, 1945-49, was intended to transform the war-torn Third Reich into a peaceable nation through a series of far-reaching political, economic, and social reforms. But amid the growing tensions between East and West these radical plans would be significantly altered, culminating in the formation of two German states in 1949. Historians have tended to view the occupation as a backdrop to the nascent Cold War or a transitional period in the history of modern Germany. Yet this thesis suggests that British participation in the Allied occupation was, in fact, much more than simply an exercise in political pragmatism or a contribution to the rebuilding of war-torn Europe. Rather, this undertaking catalysed Britainâs political and public confrontation with Nazism, laying some of the most significant and durable foundations of the postwar Anglo-German relationship.
This research utilises contemporary mass media sources and official records to explore British images and perceptions of Germany under occupation, scrutinising the interactions of decision-makers, the media, and the public. It begins with an examination of the pervasive culture war that emerged in wartime Britain over the precise interpretation and resolution of the so-called âGerman problemâ. The thesis then goes on to consider public portrayals of the occupation vis-Ă -vis the evolution of official policy, beginning in the summer of 1945 when British policymakers responded to popular demands for a âhard peaceâ and approved a rigorous programme of denazification, re-education, and demilitarisation. In the coming years, scandals engulfed the public image of the British occupiers, threatening to undermine Britainâs claims on âwinning the peaceâ and even prompting an official public relations campaign. The mass market press led calls for an abrupt end to the occupation, fearing it was undermining the nationâs prestige while failing to adequately address the threat still posed by Germany. At around the same time, Britainâs political and military leaders reassessed their position in the face of the Cold War, turning towards the reconstruction and rehabilitation of western Germany. By 1949, a clear dichotomy had emerged, with implications reaching far beyond the immediate postwar period: while anxieties over the âGerman problemâ remained largely intact amongst substantial sections of the British press and public, with many regarding the occupation as an abject failure, policymakers were firmly set on the path towards Anglo-German reconciliation and alliance.AHRC DTP full scholarshi
