    The study of employee engagement has been a key focus of management for over three decades. The academic literature on engagement has generated multiple definitions but there are two primary models of engagement: the Personal Engagement Model of Kahn (1990), and the Work Engagement Model (WEM) of Schaufeli et al., (2002). While the former is cited by most authors as the seminal work on engagement, research has tended to focus on elements of the model and most theoretical work on engagement has predominantly used the WEM to consider the topic. The purpose of this study was to test all the elements of the nomological network of the PEM to determine whether the complete model of personal engagement is viable. This was done using data from a large, complex public sector workforce. Survey questions were designed to test each element of the PEM and administered to a sample of the workforce (n = 3,103). The scales were tested and refined using confirmatory factor analysis and then the model was tested determine the structure of the nomological network. This was validated and the generalisability of the final model was tested across different work and organisational types. The results showed that the PEM is viable but there were differences from what was originally proposed by Kahn (1990). Specifically, of the three psychological conditions deemed necessary for engagement to occur, meaningfulness, safety, and availability, only meaningfulness was found to contribute to employee engagement. The model demonstrated that employees experience meaningfulness through both the nature of the work that they do and the organisation within which they do their work. Finally, the findings were replicated across employees in different work types and different organisational types. This thesis makes five contributions to the engagement paradigm. It advances engagement theory by testing the PEM and showing that it is an adequate representation of engagement. A model for testing the causal mechanism for engagement has been articulated, demonstrating that meaningfulness in work is a primary mechanism for engagement. The research has shown the key aspects of the workplace in which employees experience meaningfulness, the nature of the work that they do and the organisation within which they do it. It has demonstrated that this is consistent across organisations and the type of work. Finally, it has developed a reliable measure of the different elements of the PEM which will support future research in this area

    El trabajo de investigaci贸n identifica un problema p煤blico que surge por una reducida participaci贸n ciudadana en la emisi贸n de observaciones, comentarios o sugerencias a los proyectos normativos elaborados por el Organismo de Evaluaci贸n y Fiscalizaci贸n Ambiental - OEFA debido a que, durante el per铆odo del 2016 al 2019 se ha evidenciado que el n煤mero de participantes efectivos no supera ni el 1 % de los participantes potenciales (administrados del OEFA y EFA de nivel nacional, regional y local). Entre las principales causas del problema p煤blico identificado se encuentra la ausencia de procedimientos claros y espec铆ficos, la falta de conocimiento sobre las oportunidades para participar, as铆 como una d茅bil promoci贸n de los procesos de participaci贸n toda vez que, la ciudadan铆a interesada en temas de fiscalizaci贸n ambiental no cuenta con los canales id贸neos ni recibe de manera oportuna la informaci贸n pertinente que les garantice su derecho constitucional a la participaci贸n. Para solucionar este problema p煤blico se propone el dise帽o, creaci贸n e implementaci贸n de un Sistema de Regulaci贸n y Participaci贸n en Fiscalizaci贸n Ambiental (SIREFA), la cual elevar铆a la participaci贸n ciudadana en la emisi贸n de observaciones, comentarios o sugerencias a los proyectos normativos elaborados por el OEFA. Este sistema es una herramienta tecnol贸gica intuitiva que cuenta con cuatro (4) componentes que le permite, tanto a las y los usuarios internos (servidores(as) civiles del OEFA), as铆 como a las y los usuarios externos (ciudadan铆a en general), acceder a los textos en formato editable de los proyectos normativos y realizar los aportes pertinentes, de manera f谩cil y r谩pida, generando de esta forma, buenas pr谩cticas de gesti贸n p煤blica en la categor铆a consulta y participaci贸n ciudadana, al constituirse en una de las primeras plataformas de su naturaleza en Am茅rica Latina y El Caribe. El prototipo del SIREFA es un proyecto viable en su desarrollo e implementaci贸n toda vez que, garantiza el derecho a la participaci贸n de la ciudadan铆a y, al mismo tiempo, se ha justificado que el SIREFA contar铆a con viabilidad, deseabilidad y factibilidad debido a que, la propuesta se alinea al planeamiento estrat茅gico de la entidad para la mejora normativa y digitalizaci贸n; y sobre todo se construye sobre las experiencias de optimizaci贸n de los procesos digitales para la participaci贸n de actores clave de sus procesos.The research work identifies a public problem that arises from a reduced citizen participation in the issuance of observations, comments or suggestions to the normative projects prepared by the Environmental Assessment and Enforcement Agency - OEFA because, during the period from 2016 to 2019 the number of effective participants does not exceed 1 % of potential participants. Among the main causes of the identified public problem is the absence of clear and specific procedures, the lack of knowledge about the opportunities to participate, as well as a weak promotion of the participation processes, since the citizens interested in environmental enforcement issues do not have the appropriate channels nor do them receive in a timely manner the pertinent information that guarantees its constitutional right to participation. To solve this public problem, the design, creation and implementation of a System of Regulation and Participation in Environmental Enforcement (SIREFA) is proposed, which would increase citizen participation in the issuance of observations, comments or suggestions to the normative projects prepared by the OEFA. This system is an intuitive technological tool that has four (4) components that allow internal as well as external users, to access the texts of the normative projects in editable format and allows them to register the observations, comments or pertinent suggestions, easily and quickly, thus generating good public management practices in the category of citizen consultation and participation, by becoming one of the first platforms of its kind in Latin America and the Caribbean. The SIREFA prototype is a viable project in its development and implementation since it guarantees the right to citizen participation, in a simple and fast way access to the texts of the normative projects, in editable format, justifying that the SIREFA has viability, desirability and feasibility because the proposal is aligned with the entity's strategic planning for regulatory improvement and digitization; and, above all, it is built on experiences of optimization of digital processes for the participation of key actors in their regulatory processes

    Radical Left Parties and the Role of Euroscepticism

    Globalization has shifted the political competition landscape in Western Europe. Extensive research has studied the impact of this on the radical right, yet little attention has been paid to the radical left. This dissertation, comprised of three papers, analyses the impact of the increased European integration emphasis on the radical left. My first paper analyses whether there is a beneficial policy position for the radical left on European integration. The chapter finds that there is an electoral benefit to a Eurosceptic position for radical left parties but also shows that this benefit is constrained when a Eurosceptic competitor, i.e. radical right party, enters the party system. My second paper follows from this and examines an alternative approach for the radical left on European integration. While the benefit of a Eurosceptic position can be constrained, blurring the position on European integration can help avoid losing pro-EU voters. The chapter finds that position blurring on EU integration is beneficial when there is electorate polarization but harmful when the electorate is in consensus on EU integration. When there is consensus, radical left parties benefit from a clear position on EU integration. My third paper is co-authored with Royce Carroll and zooms into the findings of the first two chapters by examining the demand side of Euroscepticism. The paper finds that European integration is an important issue for vote choice of the electorate. The results of the chapter show that the more Eurosceptic voters are, the higher their propensity to vote for a radical left party becomes. These three papers demonstrate how the issue of European integration is in the centre of radical left strategy from a supply and demand side perspective. This thesis contributes to the literature by providing a detailed understanding of the success of small parties beyond their issue ownership

    .E-sports games can drive the sports industry forward and sponsorship is the best way to engage consumers of this new sport. The purpose of this study is to examine the effect of sponsorship image and consumer participation in co-creation consumption activities on fans鈥 sponsorship response (represented by the variables interest, purchase intention and word of mouth) in e-sports. Four antecedent variables build sponsorship image (i.e., ubiquity of sport, sincerity of sponsor, attitude to sponsor and team identification). A quantitative approach is used for the purposes of this study. Some 445 questionnaires were filled in by fans who watch e-sports in Spain; these are analyzed using partial least squares structural equation modeling (PLS-SEM). The outcomes show that sponsor antecedents are crucial factors if a sponsor wants to change their sponsorship image and influence sponsorship response, and that it is also possible to use participation to improve responsesS

    Exploring the Structure of Scattering Amplitudes in Quantum Field Theory: Scattering Equations, On-Shell Diagrams and Ambitwistor String Models in Gauge Theory and Gravity

    In this thesis I analyse the structure of scattering amplitudes in super-symmetric gauge and gravitational theories in four dimensional spacetime, starting with a detailed review of background material accessible to a non-expert. I then analyse the 4D scattering equations, developing the theory of how they can be used to express scattering amplitudes at tree level. I go on to explain how the equations can be solved numerically using a Monte Carlo algorithm, and introduce my Mathematica package treeamps4dJAF which performs these calculations. Next I analyse the relation between the 4D scattering equations and on-shell diagrams in N = 4 super Yang-Mills, which provides a new perspective on the tree level amplitudes of the theory. I apply a similar analysis to N = 8 supergravity, developing the theory of on-shell diagrams to derive new Grassmannian integral formulae for the amplitudes of the theory. In both theories I derive a new worldsheet expression for the 4 point one loop amplitude supported on 4D scattering equations. Finally I use 4D ambitwistor string theory to analyse scattering amplitudes in N = 4 conformal supergravity, deriving new worldsheet formulae for both plane wave and non-plane wave amplitudes supported on 4D scattering equations. I introduce a new prescription to calculate the derivatives of on-shell variables with respect to momenta, and I use this to show that certain non-plane wave amplitudes can be calculated as momentum derivatives of amplitudes with plane wave states
