This study explores partnership working as a mechanism for effective public service delivery. It investigates into how Public-Social Enterprise Partnerships (P-SEPs) can utilise innovative models of user involvement and Service Innovation (SI) in the co-design and co-delivery of user-led socially-oriented services to young adults (18-24) in East England. It identifies the inability of P-SEPs to conceptually explore innovative models of user involvement and SI when engaging young-adult end users in the co-design and co-delivery of user-led solutions to `wicked` issues like `rough sleeping` as a gap in knowledge which I will explore three interrelated research questions in filling. This study draws conceptual inspiration from the network theory, the Pragmatic research paradigm and the inductive-deductive research strategy in exploring the Concurrent Mixed Method underpinned by Likert-scale questionnaires and semi-structure interviews as my data gathering instruments. The emergent conceptual framework from my data analyses posits that high users` perception of their involvement in the co-design and co-delivery of user-led public services can engineer satisfaction, transformational outcomes and high service quality. A fieldtrip provided the conceptual opportunity for me to explore three multiple-case studies in gathering qualitative data through semi-structured interviews administered to staff as these were coded, thematised and analysed using NVivo. Quantitative data from questionnaires administered to end users were analysed using Excel. Evidence gleaned from both strands was integrated and triangulated in complementing and enhancing my research findings. This study challenges misconceptions and dominant ideologies which underpin user involvement while making three interconnected contributions to knowledge. First, it extends the frontiers of knowledge in the discipline by creating new insights and articulating four innovative models of user involvement. Second, at the practical level, it contributes to the ongoing debate on conceptualising, modernising and delivering more effective userengineered public services by informing professional practice and policymaking. And third, at the theoretical level, it contributes towards the development of a theory on user involvement. It thus underlines the factual conclusion that high users` perception of their involvement in the co-design and co-delivery of user-led outcomes can engineer high user satisfaction, high service quality and transformational outcomes. It successfully re-positions the debates on user involvement on new conceptual and empirical grounds.

Previous research highlighted consumer dissatisfaction with fashion clothing products on offer. There is a lack of information about real consumers needs due to the industry standards of beauty and behaviour as well as a constant rush for innovation that feeds fashion cycles. This research identifies the elements that will enable fashion clothing companies to become more inclusive, and aims to find a methodological relationship between the stakeholders in the fashion industry: consumers, designers and companies. The research considered the difference between a mature market as opposed to emergent ones, and addressed differences between Western and Eastern cultures.

Dieser Beitrag zeigt, inwiefern eine digitale Lernortkooperation unter Gesichtspunkten des Wissenstransfers mithilfe eines Online-Berichtsheftes umgesetzt werden kann. Dazu wird das vom BMBF geförderte Verbundprojekt ‚Diffusion digitaler Technologien in der beruflichen Bildung durch Lernortkooperation‘ (DiBBLok) vorgestellt und inblicke in die Ergebnisse einer quantiativen Strukturdatenanalyse des Online-Berichtsheftes BLok gegeben.

<p>No organisation has an endless and unlimited supply of money, especially in a recessive economy, and therefore decisions have to be made as to which areas an organisation will invest in. As organisations, such as YZ1 financial services organisation, are focused on seeing returns on investment (ROI), implementing software that is not being used&nbsp<br>will not render any benefits to the organisation. Research problem: Project Managers (PMs) in YZ organisation&rsquo<br>s IT department need to perform mandated processes, as&nbsp<br>defined in their centralised repository. PMs need to use Financial and Planning Software (FPS)2 software to perform certain project management activities, as required by their&nbsp<br>job function. However, it was found that MPP3 software, another tool, was used for more detailed project schedules, as well as activities that were not strictly enforced by&nbsp<br>management, the Project Office or the Quality Assurance team. Therefore, from this discovery, it was not clear whether the intended benefit of implementing this mandatory&nbsp<br>software (FPS) was being realised &ndash<br>since implementing software that is not being utilised fully would not deliver the intended benefits to the IT department (Devaraj &amp<br>Kohli&nbsp<br>2003), even if the software is termed &lsquo<br>mandatory&rsquo<br>. Objective: The primary objective of this research was to explore and optimise the key success factors for an effective&nbsp<br>implementation of mandatory software in a department, in order to derive the intended business benefits. Literature Review: Literature was reviewed in the search for models or&nbsp<br>theories that explore the relationship between the use of mandatory software and the achievement of business benefits. The Information Management Body of Knowledge&nbsp<br>(IMBOK) was selected as this framework defines the relationship between IT and the realisation of business benefits, and ultimately the achievement of any business strategy. The literature review focused predominantly on the level of user involvement, change management, as well as factors that influence the usage of mandatory software by&nbsp<br>individuals. 1. The name of the organisation utilised has been changed. Refer to Ethical Consideration 2. The name of the tools utilised has been changed. Refer to Ethical&nbsp<br>Consideration and list of acronyms 3. The name of the tools utilised has been changed. Refer to Ethical Consideration and list of acronyms. Focus was given to organisational factors affecting usage, such as top management support and organisational processes. A model was compiled using unique constructs in the Technology Acceptance Model&nbsp<br>(and TAM2), the Motivational Model (MM) and the Model of PC Utilisation (MPCU) &ndash<br>in order to test user acceptance of mandatory software. The literature study concludes with a&nbsp<br>review of an approach to benefits management including five stages, namely: identifying and structuring benefits, planning for the realisation of benefits, executing the plan, in&nbsp<br>addition to the evaluation and the review. Research design and methodology: A case study was used in this research, as it examined the phenomenon in its natural setting,&nbsp<br>&nbsp<br>&nbsp<br>employing multiple methods of data collection to gather information from a few entities (groups and data sources). In this way, it was not limited to only qualitative or quantitative&nbsp<br>approaches, but utilised mixed methods instead. A mixed methods approach was used in order to elaborate, enhance and clarify the results from the qualitative research&nbsp<br>through the results of the quantitative analysis. Findings: The main finding, based on the compilation of three models of user acceptance, proved that FPS was not being utilised&nbsp<br>as intended. There was also no evidence of an improvement in business operations. Therefore, benefits management was negatively impacted. Organisational processes were&nbsp<br>dentified as the most important organisational factor, influencing the usage of FPS software. Own technological capability was considered to be the least important factor,&nbsp<br>as respondents believed that they had sufficient IT skills in order to learn how to use FPS software. Change management was rated negatively<br>and as a result, it impacted the&nbsp<br>usage of FPS, as users were not involved in the decision to implement, and had limited interaction in the implementation process. In addition, there was no evidence found that&nbsp<br>benefits management was conducted in the IT department<br>and therefore, the impact of using alternative software could not be quantitatively assessed. Recommendations: In concluding this research, it is recommended that the &ldquo<br>best practice&rdquo<br>, derived from the pertinent literate should be followed more diligently if YZ organisation is to benefit from the&nbsp<br>implementation of mandatory software. For example, in this research, it was found that top management&rsquo<br>s support of FPS (second most important organisational factor influencing use) was lacking, despite the literature suggestion that senior management involvement in changing technology is crucial for organisational commitment. It is&nbsp<br>suggested that a more formal approach to benefits management should be implemented. It is also recommended that further study should be conducted &ndash<br>in order to explore&nbsp<br>the applicability of the Japanese framing (achieving benefits from IT software through the concept of strategic instinct, rather than strategic alignment) in the context of a&nbsp<br>developing country (such as South Africa).</p>

Research Doctorate - Doctor of Philosophy (PhD)<br>Next-generation wireless communication systems are expected to deliver extreme improvements in throughput and energy efficiency, in an era of pervasive machine learning applications. Meeting the ambitious technical objectives set out in beyond-5G visions requires a collaborative effort among a large number of wireless access points. Leveraging advances in optimisation theory, this thesis studies collaborative radio resource management for the two most promising cloud-based wireless network architectures: Cloud Radio Access Networks (C-RANs) and Cell-Free Massive Multiple-Input-Multiple-Output (CFmMIMO) networks. In these networks, the significant advantages achieved through centralised baseband processing, spatial multiplexing and large antenna arrays make it possible to support distributed machine learning algorithms over the air. However, on top of the traditional issue of limited available radio resources, C-RANs and CFmMIMO architectures must resolve new issues arising from the limited-capacity fronthaul links that connect the access points with the central processing unit in the cloud. Furthermore, executing distributed machine learning algorithms over dynamic and unpredictable wireless links remains a major obstacle. The first contribution of this thesis is proposing novel resource allocation solutions to improve throughput and energy efficiency for C-RANs via edge baseband processing. Here, we propose that baseband signals be partially processed at the access points instead of being fully processed at the central processing unit. We show that in the best-case scenarios, our optimisation-based edge processing approach provides up to 50% energy efficiency gain over the existing centralised compression-based solutions. We further extend our results to full-duplex transmissions, and show that full-duplexing can improve the network throughput by almost 1.5 times while tripling the energy-efficiency gain, compared with half-duplex transmissions. In the second contribution, we consider a C-RAN content delivery network where each access point stores the frequently requested content in its local cache. Local caching has been shown to substantially reduce data traffic on the fronthaul links. We propose new transmission and resource allocation algorithms that are applicable to any caching scheme. Here, both multicasting and unicasting cases are analysed in detail. Simulation results show that for a given caching scheme, our proposals can deliver up to 20% network throughput gain and 14% energy efficiency gain. In the third contribution, we propose a novel communication scheme for CFmMIMO networks to support any federated learning (FL) framework. This scheme exploits the channel hardening property of massive MIMO, where the effective channel gains remain relatively unchanged during the large-scale channel coherence time. We propose that within this coherence time, one (instead of all) iteration of an FL process is executed, thus guaranteeing the stable operation of the whole FL process. In this communication scheme, we develop successive convex approximation algorithms that allocate radio resources to minimise the FL training time. Simulation results show that our proposals reduce the FL training time by more than half compared to the heuristic approaches. In the fourth contribution of this thesis, we extend the results in the third contribution to mitigate the `straggler effect' in wireless federated learning. Here, a user with unfavorable wireless link conditions may significantly slow down the entire FL process. We study new user selection methods for CFmMIMO networks and develop algorithms that minimise the FL training time. Significantly, a reduction of up to 63% in training time has been observed in our numerical results with practical parameter settings.

XMach-1 was the first XML data management benchmark designed for general applicability [1]. It is still the only benchmark supporting a multiuser performance evaluation of XML database systems. After a brief review of XMach-1 we summarize three additionally proposed benchmarks (XMark, XOO7, Mbench) and provide a comparison between these benchmarks. We then present experiences and performance results from evaluating XML database systems with XMach-1.

Social Sciences have a relevant importance, because they assist individuals to make sense of the social world and to situate their ideas, fears, interests, values ​​and relationships at the center of the social processes they reflect and configure. However, a diagnosis made in the main doctoral programs of the Pedagogical Sciences in Cuba revealed deficiencies and deficiencies that led to the formulation of the scientific problem of the present investigation: insufficiencies in the process of interpretation of the social reality, in relation to its qualitative and complex nature, which limits the scientific performance of professionals. The object of the research is, therefore, the scientific research process of the Social Sciences and its field of action: the dynamics of information processing in the Social Sciences research process. The main research results are: a model of the dynamics of information processing in social investigations, which becomes an integrative didactic method for such processing, as a theoretical contribution, and a system of methodological procedures for processing information in the social investigations, as a practical contribution. It is revealed as essential regularity, the integrating logic between the understanding of the validity and reliability of social information and the systematization of the synthesis and the concretion of this information, consistent with a qualitative and quantitative processing of it. The pertinence and scientific feasibility of the research results was assessed satisfactorily through a consultation with experts and the corroboration of the partial application of the system of methodological procedures.
