description: A combination of dynamical mean field theory and density functional theory, as implemented in Phys. Rev. B 81, 195107 (2010), is applied to both the early and late transition metal oxides. For fixed value of the local Coulomb repulsion, without fine tuning, we obtain the main features of these series, such as the metallic character of SrVO$_3$ and the the insulating gaps of LaVO$_3$, LaTiO$_3$ and La$_2$CO$_4$ which are in good agreement with experiment. The study highlights the importance of local physics and high energy hybridization in the screening of the Hubbard interaction and how different low energy behaviors can emerge from the a unified treatment of the transition metal series.

description: We briefly survey several typical CP-conserving two-Higgs-doublet models (2HDMs) in light of current experiments. First we derive the masses and couplings of the mass eigenstates from the Lagrangians. Then we analyze the constraints from theory and oblique electroweak parameters. Finally, we delineate the status of 2HDM in light of the LHC searches, the dark matter detections and the muon $g-2$ measurement.

A study of chief executive officer (CEO) turnover in Vietnam: The link between firm performance and CEO turnover
Creators: name: Tran, Quan
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Organisational planning and management

description: The main findings of the thesis show that firm performance had significant inverse relationship with the likelihood of CEO turnover. Meanwhile, the influence of ownership structure on CEO turnover was insignificant. Interestingly, aged CEOs in Vietnamese-listed enterprises were more likely to be dismissed than young CEOs. Additionally, the probability of CEO turnover significantly increased when CEOs reached the ages of 59-61. The certain age also reduced the influence of CEO duality on CEO turnover. Together, CEO ownership negatively influenced the sensitivities of the link between firm performance and CEO turnover, although the influence is insignificant when CEOs own less than 5% of firm shares. Importantly, the thesis provides the significant and positive relationship between the percentage of independent directors and CEO turnover. Based on those findings, the thesis concludes that the efficiency of corporate governance and effectiveness of management are able to improve by increasing the independence of the Board of Management rather than other factors.

description: Let $G$ be a split connected reductive group over a finite extension $F$ of $Q_p$. We determine the extensions between unitary continuous $p$-adic and smooth mod $p$ principal series of $G(F)$ in the generic case. In order to do so, we compute Emerton's delta-functor $\mathrm{H^\bullet Ord}_{B(F)}$ of derived ordinary parts with respect to a Borel subgroup on certain induced representations of $G(F)$ using a Bruhat filtration. These extensions come into play in the $p$-adic and mod $p$ Langlands programs.

description: The Gerber-Shiu function provides a unified framework for the evaluation of a variety of risk quantities. Ever since its establishment, it has attracted constantly increasing interests in actuarial science, whereas the conventional research has been focused on finding analytical or semi-analytical solutions, either of which is rarely available, except for limited classes of penalty functions on rather simple risk models. In contrast to its great generality, the Gerber-Shiu function does not seem sufficiently prevalent in practice, largely due to a variety of difficulties in numerical approximation and statistical inference. To enhance research activities on such implementation aspects, we provide a comprehensive review of existing formulations and underlying surplus processes, as well as an extensive survey of analytical, semi-analytical and asymptotic methods for the Gerber-Shiu function, which altogether shed fresh light on its numerical methods and statistical inference for further developments. On the basis of an ambitious collection of 235 references, the present survey can serve as an insightful guidebook to model and method selection from practical perspectives as well.

description: In this review we consider in detail different theoretical topics associated with interaction in the dark sector. We study linear and nonlinear interactions which depend on the dark matter and dark energy densities. We consider a number of different models (including the holographic dark energy and dark energy in a fractal universe) with interacting dark energy (DE) and dark matter (DM), have done a thorough analysis of these models. The main task of this review was not only to give an idea about the modern set of different models of dark energy, but to show how much can be diverse dynamics of the universe in these models. We find that the dynamics of a Universe that contains interaction in the dark sector can differ significantly from the Standard Cosmological Model (SCM).

description: We study Yang-Mills lattice theories with $Sp(N_c)$ gauge group, with $N_c=2N$, for $N=1,\,\cdots,\,4$. We show that if we divide the renormalised couplings appearing in the Wilson flow by the quadratic Casimir $C_2(F)$ of the $Sp(N_c)$ group, then the resulting quantities display a good agreement among all values of $N_c$ considered, over a finite interval in flow time. We use this scaled version of the Wilson flow as a scale-setting procedure, compute the topological susceptibility of the $Sp(N_c)$ theories, and extrapolate the results to the continuum limit for each $N_c$.

description: In the present work, we developed a sustainable and effective antimicrobial surface film based on Micro-Fibrillated Cellulose. The resulting porous cellulose thin film is barely noticeable to human eyes due to its sub-micron thickness, of which the coverage, porosity and microstructure can be modulated by the formulations developed. Using goniometers and a quartz crystal microbalance (QCM), we observed a threefold reduction in water contact angles and accelerated (more than 50% faster) water evaporation kinetics on the cellulose film. The thin film exhibits not only a rapid inactivation effect against SARS-CoV-2 in 5 minutes, following deposition of the virus loaded droplets, but also an exceptional ability to reduce contact transfer of liquid, e.g. respiratory droplets, onto surfaces such as artificial skin by more than 90%. It also exhibits excellent antimicrobial performance in inhibiting the growth of both gram-negative and gram-positive bacteria (E.coli and S.epidermidis) due to the excellent porosity and hydrophilicity. Additionally, the cellulose film shows nearly 100% resistance to skin scraping in dry condition thanks to its strong attachment to the substrate, whilst good removability once wetted, suggesting its practical suitability for daily use. Importantly, the coating can be formed on solid substrates readily by spraying and requires solely a simple formulation of a plant-based cellulose material with no additives, rendering it a scalable, affordable and green solution for antimicrobial surfaces. Implementing such cellulose films could thus play a significant role in controlling future pan- and epidemics, in particularly during the first phase when appropriate medication needs to be developed.

description: We describe a type of n-point function associated to strongly regular vertex operator algebras V and their irreducible modules. Transformation laws with respect to the Jacobi group are developed for 1-point functions. For certain elements in V, the finite-dimensional space spanned by the corresponding 1-point functions for the inequivalent irreducible modules is shown to be a vector-valued weak Jacobi form. A decomposition of 1-point functions for general elements is proved, and shows that such functions are typically quasi-Jacobi forms. Zhu-type recursion formulas are proved; they show how an n-point function can be written as a linear combination of (n-1)-point functions with coefficients that are quasi-Jacobi forms.

Thickness bound for nonlocal wide-field-of-view metalenses
Creators: name: Li, Shiyu

Publisher: name: arXiv
Year: 2022
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: Metalenses -- flat lenses made with optical metasurfaces -- promise to enable thinner, cheaper, and better imaging systems. Achieving a sufficient angular field of view (FOV) is crucial toward that goal and requires a tailored incident-angle-dependent response. Here, we show that there is an intrinsic trade-off between achieving a desired broad-angle response and reducing the thickness of the device. It originates from the Fourier transform duality between space and angle. One can write down the transmission matrix describing the desired angle-dependent response, convert it to the spatial basis where its degree of nonlocality can be quantified through a lateral spreading, and determine the minimal device thickness based on such a required lateral spreading. This approach is general. When applied to wide-FOV lenses, it predicts the minimal thickness as a function of the FOV, lens diameter, and numerical aperture. The bound is tight, as some inverse-designed multi-layer metasurfaces can approach the minimal thickness we found. This work offers guidance for the design of nonlocal metasurfaces, proposes a new framework for establishing bounds, and reveals the relation between angular diversity and spatial footprint in multi-channel systems.
The diversity of diffusion of information and communication technologies in the hospitality and tourism sector - with particular reference to the small and medium hospitality enterprise
Creators: name: Murphy, Hilary
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Other commerce, management, tourism and services not elsewhere classified

description: This thesis presents an overview of a selection of previously published works from 1994-2003. It focuses on the diffusion of information and communication technologies (ICTs) in the hospitality and tourism sector, with particular reference to small and medium-sized hospitality enterprises. It specifically evaluates the critical internal and external factors that influence the diffusion of ICTs in this sector.
 The first chapter introduces the overall research question, the publisher works and the models that are used to guide the progress of this thesis and its structure. It reveals the phases of investigation throughout the research period and provides a framework for the following chapter, which reviews the published works.
 The second chapter presents a review of the selected publications in the context of a contemporaneous literature review that starts from a baseline of Gamble's 1984 model of diffusion. It builds towards populating a new model that takes into account the emerging internal and external factors that emerge not only from these works, but also from other sources that impact on this sector over the research period.
 The third chapter outlines the research process using a timeline model and provides a critical review of that process in terms of the methodologies used in the phases of the research. It highlights and justifies the pluralistic, pragmatic approach adopted and concludes with a review and reflection on the methodologies chosen.
 The final chapter evaluates the contribution to knowledge and highlights the empirical evidence in the new model that has emerged as a result of this thesis. It considers the direction of future research and reflects on the overall thesis.

description: Stimuli responsive surface structures attract increasing attention dueto a large variety of envisioned applications. The controlled organization ofpoly(N-isopropyl acrylamid), PNIPAM microgel particles at solid surfaces in-spired numerous research activities. In this review article, we briefly discuss theswelling/deswelling properties of adsorbed microgel particles in comparison tothe behavior in the bulk phase. The presence of the solid interface highly influ-ences and changes their behavior with respect to the properties in solution. Fur-thermore, the confinement on a solid substrate allows the direct and in-situ in-vestigation of the mechanical properties of the microgel particles. Additionally,we briefly review the research on microgel particles at liquid interfaces. At theseinterfaces new interesting effects occur. Moreover, we discuss some interestingwork on potential applications. In this context, microgel particles are often usedas an active component for responsive coatings of various functionality envision-ing applications, e.g. in medicine, biotechnology, and nanooptics.

description: This paper introduces a library of algorithms for representing cloud microphysics in numerical models. The library is written in C++, hence the name libcloudph++. In the current release, the library covers three warm-rain schemes: the single- and double-moment bulk schemes, and the particle-based scheme with Monte-Carlo coalescence. The three schemes are intended for modelling frameworks of different dimensionality and complexity ranging from parcel models to multi-dimensional cloud-resolving (e.g. large-eddy) simulations. A two-dimensional prescribed-flow framework is used in example simulations presented in the paper with the aim of highlighting the library features. The libcloudph++ and all its mandatory dependencies are free and open-source software. The Boost.units library is used for zero-overhead dimensional analysis of the code at compile time. The particle-based scheme is implemented using the Thrust library that allows to leverage the power of graphics processing units (GPU), retaining the possibility to compile the unchanged code for execution on single or multiple standard processors (CPUs). The paper includes complete description of the programming interface (API) of the library and a performance analysis including comparison of GPU and CPU setups.
description: The library description has been updated to the new library API (i.e. v0.1 -> v0.2 update). The key difference is that the model state variables are now mixing ratios as opposed to densities. The particle-based scheme was supplemented with the "particle recycling" process.

Constraining the Z' Mass in 331 Models using Direct Dark Matter Detection

description: We investigate a so-called 331 extension of the Standard Model gauge sector which accommodates neutrino masses and where the lightest of the new neutral fermions in the theory is a viable particle dark matter candidate. In this model, processes mediated by the additional $Z^{\prime}$ gauge boson set both the dark matter relic abundance and the scattering cross section off of nuclei. We calculate with unprecedented accuracy the dark matter relic density, including the important effect of coannihilation across the heavy fermion sector, and show that indeed the candidate particle has the potential of having the observed dark matter density. We find that the recent LUX results put very stringent bounds on the mass of the extra gauge boson, $M_{Z^{\prime}} \gtrsim 2$~TeV, independently of the dark matter mass. We also comment on regime where our bounds on the $Z^{\prime}$ mass may apply to generic 331-like models, and on implications for LHC phenomenology.

description: Extreme-value distributions are studied in the context of a broad range of problems, from the equilibrium properties of low-temperature disordered systems to the occurrence of natural disasters. Our focus here is on the ground-state energy distribution of disordered many-body quantum systems. We derive an analytical expression that, upon tuning a parameter, reproduces with high accuracy the ground-state energy distribution of the systems that we consider. For some models, it agrees with the Tracy-Widom distribution obtained from Gaussian random matrices. They include transverse Ising models, the Sachdev-Ye model, and a randomized version of the PXP model. For other systems, such as Bose-Hubbard models with random couplings and the disordered spin-1/2 Heisenberg chain used to investigate many-body localization, the shapes are at odds with the Tracy-Widom distribution. Our analytical expression captures all of these distributions, thus playing a role to the lowest energy level similar to that played by the Brody distribution to the bulk of the spectrum.

description: Categorical probability has recently seen significant advances through the formalism of Markov categories, within which several classical theorems have been proven in entirely abstract categorical terms. Closely related to Markov categories are gs-monoidal categories, also known as CD categories. These omit a condition that implements the normalization of probability. Extending work of Corradini and Gadducci, we construct free gs-monoidal and free Markov categories generated by a collection of morphisms of arbitrary arity and coarity. For free gs-monoidal categories, this comes in the form of an explicit combinatorial description of their morphisms as structured cospans of labeled hypergraphs. These can be thought of as a formalization of gs-monoidal string diagrams ($=$term graphs) as a combinatorial data structure. We formulate the appropriate $2$-categorical universal property based on ideas of Walters and prove that our categories satisfy it. We expect our free categories to be relevant for computer implementations and we also argue that they can be used as statistical causal models generalizing Bayesian networks.

description: The hypocholesterolemic effect of peptides present in crude casein hydrolysate using trypsin from Bifidobacterium animalis subsp. lactis (Bb-12) culture grown in casein solution or in MRS broth were compared with the control (unhydrolysed crude casein). These samples have shown to reduce cholesterol level in vitro to varying degree between 24-87%. The unhydrolysed crude casein (control) has shown not to have a reducing effect on cholesterol level. The reduction level of cholesterol was found to be dependant on the degree of hydrolysis. Fractions obtained after size exclusion from crude casein hydrolysate formed by trypsin after 48h hydrolysis have shown to reduce cholesterol level to degree vary between 2.7% to 50%. Bb-12 or trypsin crude casein hydrolysates were also found to possess angiotensin-converting enzyme (ACE) inhibitory activity in vitro to a varying degree between 29% and 38%, respectively. Unhydrolysed crude casein showed no real effect on ACE inhibitory activity. Trypsin hydrolysate has slightly more effect on ACE activity than Bb-l2. A relationship was also found between ACE-inhibitory activity and degree of hydrolysis. Fractions of crude casein hydrolysate after 48h hydrolysis with trypsin by size exclusion have shown to have ACE-inhibitory activity varying between 37% and 50%. Several identified ACE-inhibitory peptides from active fractions were found to have Phe, Trp, Tyr, Arg, Lys or Pro at their ultimate C-terminal position, making them a possible candidate for ACE-inhibitory activity. Further analysis on the profiles of casein and whey protein fractions, obtained by fast protein liquid chromatography (FPLC), of skimmed milk and four different commercial types of probiotic health drinks, and casein profile of added Bb-12 culture were investigated to study the possible effect of probiotics on milk proteins. Differences in protein-profile were found between the control and the four commercial probiotic health drinks as well as with added Bb-12 culture. Whey proteins were more resistance to hydrolysis than caseins.

description: We solve Dehn's isomorphism problem for virtually torsion-free relatively hyperbolic groups with nilpotent parabolic subgroups. We do so by reducing the isomorphism problem to three algorithmic problems in the parabolic subgroups, namely the isomorphism problem, separation of torsion (in their outer automorphism groups) by congruences, and the mixed Whitehead problem, an automorphism group orbit problem. The first step of the reduction is to compute canonical JSJ decompositions. Dehn fillings and the given solutions of the algorithmic problems in the parabolic groups are then used to decide if the graphs of groups have isomorphic vertex groups and, if so, whether a global isomorphism can be assembled. For the class of finitely generated nilpotent groups, we give solutions to these algorithmic problems by using the arithmetic nature of these groups and of their automorphism groups.
description: 76 pages. This version incorporates referee comments and corrections. The main changes to the previous version are a better treatment of the algorithmic recognition and presentation of virtually cyclic subgroups and a new proof of a rigidity criterion obtained by passing to a torsion-free finite index subgroup.

Several of the examples also support a conjecture of Brumer and Kramer on abelian varieties associated to Siegel modular forms with paramodular level structures.

description: Obtaining models that can be used for control is of utmost importance to ensure the guidance and navigation of spacecraft, like a Generic Parafoil Return Vehicle (GPRV). In this paper, we convert a nonlinear model of the atmospheric flight dynamics of an GPRV to a Linear Parameter-Varying (LPV) description, such that the LPV model is suitable for navigation control design. Automated conversion methods for nonlinear models can result in complex LPV representation, which are not suitable for controller synthesis. We apply several state-of-the-art techniques, including learning based approaches, to optimize the complexity and conservatism of the LPV embedding for an GPRV. The results show that we can obtain an LPV embedding that approximates the complex nonlinear dynamics sufficiently well, where the balance between complexity, conservatism and model performance is optimal.

description: It is well known that the power spectrum is not able to fully characterize the statistical properties of non-Gaussian density fields. Recently, many different statistics have been proposed to extract information from non-Gaussian cosmological fields that perform better than the power spectrum. The Fisher matrix formalism is commonly used to quantify the accuracy with which a given statistic can constrain the value of the cosmological parameters. However, these calculations typically rely on the assumption that the likelihood of the considered statistic follows a multivariate Gaussian distribution. In this work we follow Sellentin & Heavens (2017) and use two different statistical tests to identify non-Gaussianities in different statistics such as the power spectrum, bispectrum, marked power spectrum, and wavelet scatering transform (WST). We remove the non-Gaussian components of the different statistics and perform Fisher matrix calculations with the \textit{Gaussianized} statistics using Quijote simulations. We show that constraints on the parameters can change by a factor of $\sim 2$ in some cases. We show with simple examples how statistics that do not follow a multivariate Gaussian distribution can achieve artificially tight bounds on the cosmological parameters when using the Fisher matrix formalism. We think that the non-Gaussian tests used in this work represent a powerful tool to quantify the robustness of Fisher matrix calculations and their underlying assumptions. We release the code used to compute the power spectra, bispectra, and WST that can be run on both CPUs and GPUs.

description: We present a classical analysis on the issue of vector superluminality in the decoupling limit ghost-free massive gravity with a Minkowski reference metric. We show explicitly in the Lorenz gauge that the theory is free of superluminal vector excitations around a nontrivial solution at the cubic order in the fields. In the same gauge, we demonstrate that superluminal vector modes arise at the quartic order and compute some superluminal propagating solutions. We then generalize our findings to all orders in a gauge-independent way. We check the physical consistency of the vector superluminalities, arguing that they are not physically detectable in the perturbation theory but could be trusted classically in the strong coupling region. Nevertheless, these superluminalities involve only low frequency group and phase velocities and are unable to determine the acausality of the theory.

description: In the hybrid kT-factorization formula, one initial-state parton momentum is space-like and carries non-vanishing transverse components, while the other is on-shell. We promote this factorization formula to next-to-leading order. Studying the partonic cross section, we identify all soft and collinear divergencies in the real and virtual contribution, and recognize that all non-cancelling ones can be attributed to PDF evolution, evolution kernel, and target impact factors. In result, we construct a framework that may be used to compute NLO impact factors in general. In particular, we recover known expressions for inclusive NLO quark-and gluon impact factor corrections.

Costs, benefits and barriers to the application of hygiene management systems in the United Kingdom food industry

description: Hazard Analysis Critical Control Point (HACCP) is the system of choice for the Food Standards Agency in attempting to improve risk management within the UK food industry. Informing the debate surrounding the potential barriers to HACCP implementation, this research aimed to identify the factors influencing the uptake of such systems and profile the potential costs and benefits of their implementation either individually or as part of industry wide initiatives. Results from a 1997 postal survey showed that 69% of UK food manufacturers reported having implemented HACCP, compared to only 15% of caterers and 13%o of retailers. Business size, status, managerial risk perceptions and training levels were associated with use of HACCP within individual industry sectors. The experience of eight case studies suggested that HACCP systems had been able to be implemented within the reasonable financial means of businesses both large and small. Although tangible financial benefits as a result of HACCP were experienced by only one case study, the less tangible benefits of improved food safety control through HACCP were recognised. Evaluation of a sector wide HACCP initiative for English retail butchers identified average implementation costs of f859. Although significant improvements in HACCP related knowledge and ability were delivered by the training provided, many managers believed that they would require further support to help maintain their system. Results from a Vickrey auction suggested that a substantial proportion of consumers would be willing to pay more for HACCP, although once mandatory, the system attracts lower premiums. Recommendations made for further action in promoting the wider use of HACCP include the need for monitoring of HACCP implementation rates, the provision of further evidence on the likely costs and benefits of HACCP and the need to ensure a sound basis for HACCP by improving general levels of hygiene practice and hygiene training.

description: Second-order optimality conditions for vector nonlinear programming problems with inequality constraints are studied in this paper. We introduce a new second-order constraint qualification, which includes Mangasarian-Fromovitz constraint qualification as a particular case. We obtain necessary and sufficient conditions for weak efficiency of problems with a second-order pseudoconvex vector objective function and quasiconvex constraints. We also derive Lagrange multiplier characterizations of the solution set of a scalar problem with a second-order pseudoconvex objective function and quasiconvex inequality constraints, provided that one of the solutions and the Lagrange multipliers in the Karush-Kuhn-Tucker conditions are known. At last, we introduce a notion of a second-order KKT-pseudoconvex problem with inequality constraints. We derive sufficient and also necessary conditions for efficiency of second-order KKT-pseudoconvex problems. Three examples are presented.
description: The submission contains 15 pages. I replaced the first version of the paper by another one, because I have published the introduced constraint qualification in another article. In this version it is replaced by a new second-order constraint qualification, and therefore a new theorem appears. I have added a new section with new results also
Bayesian information engine that optimally exploits noisy measurements

description: We have experimentally realized an information engine consisting of an optically trapped, heavy bead in water. The device raises the trap center after a favorable "up" thermal fluctuation, thereby increasing the bead's average gravitational potential energy. In the presence of measurement noise, poor feedback decisions degrade its performance; below a critical signal-to-noise ratio, the engine shows a phase transition and cannot store any gravitational energy. However, using Bayesian estimates of the bead's position to make feedback decisions can extract gravitational energy at all measurement noise strengths and has maximum performance benefit at the critical signal-to-noise ratio.

description: The paper presents a combination of the time-parallel "parallel full approximation scheme in space and time" (PFASST) with a parallel multigrid method (PMG) in space, resulting in a mesh-based solver for the three-dimensional heat equation with a uniquely high degree of efficient concurrency. Parallel scaling tests are reported on the Cray XE6 machine "Monte Rosa" on up to 16,384 cores and on the IBM Blue Gene/Q system "JUQUEEN" on up to 65,536 cores. The efficacy of the combined spatial- and temporal parallelization is shown by demonstrating that using PFASST in addition to PMG significantly extends the strong-scaling limit. Implications of using spatial coarsening strategies in PFASST's multi-level hierarchy in large-scale parallel simulations are discussed.

description: We discuss an aspect of string theory which has been tackled from many different perspectives, but incompletely: the role of nonlocality in the theory and its relation to the geometric shape of the string. In particular, we will describe in quantitative terms how one can zoom out from an extended object such as the string in such a way that, at sufficiently large scales, it appears structureless. Since there are no free parameters in free-string theory, the notion of large scales will be unambiguously determined. In other words, we will be able to answer the question: How and at which scale can the string be seen as a particle? In doing so, we will employ the concept of spectral dimension in a new way with respect to its usual applications in quantum gravity. The operational notions of worldsheet and target spacetime dimension in string theory are also clarified and found to be in mutual agreement.

Implementing sustainability through community participation : Methods and processes involved in strategy development
Creators: name: Collins, Andrea
Publisher: name: Cardiff Metropolitan University

Subjects: Information systems for sustainable development and the public good

description: Sustainable development is one of the most important international policy agendas of the 21st Century and involves the development of policies that integrate environmental and development issues with those that are central to poverty and social inequalities. While it is imperative that the policymaking process begins at the local level, there is uncertainty surrounding its implementation. 'Going for Green' was the UK Government's approach to achieving sustainable development at the local level. This thesis has developed a model research process to evaluate how the initiative's Pilot Sustainable Communities Project was implemented within two comparative project areas in Merthyr Tydfil (South Wales). The case study was selected as a research framework, combining quantitative and qualitative research methods. To assist in the collection of empirical data and respond to changes during the initiative's implementation, the research process was divided into three interrelated phases (exploratory, process monitoring and explanatory). An analysis was made of the scope, stage, significance and level of participation, and also how the 'local' community was defined. Empirical data was organised using a case study database and analysed at three different levels: initial preparatory work, a general analytic strategy and the use of analytic techniques. Research findings have indicated that there is a need for sustainability to be locally defined, and reflect how the environment is perceived and understood. Encouraging participation amongst a broad range of community stakeholders requires the development of different approaches based on local identities. Understanding recent social and cultural changes that have occurred within a particular locality can assist in their identification. The thesis concludes that community studies are important in developing and evaluating initiatives that promote sustainable development at the local level. As a research approach they provide an understanding of how communities operate and identify ways of involving them more effectively.
