title: Reading V.S. Naipaul : fiction and history 1967-1987
Creators: name: Prescott, Lynda
Publisher: name: The Open University
Year: 1990

description: V. S. Naipaul has published almost equal amounts of fiction and nonfiction; he maintains that his nonfictional writing is an integral part of his work. This thesis is concerned with the way readers process the two types of narrative, with special reference to historical writing and the novel. After a brief introductory survey of Naipaul's writing to date, chapter 1 explores some of the philosophical and historical issues underlying a comparative study of fiction and history. In chapter 2 attention switches to the reader's role; selected aspects of reader-response criticism are discussed in order to generate some questions that will need to be considered in a theory of reading taking account of fictional and nonfictional texts. Chapter 3 advances such a theory, based on the idea of opposing centrifugal and centripetal tendencies in reading. In chapters 4-6 this theory is tested with three sets of readers, using two of Naipaul's books from the late 1960s, a novel (The Mimic Men) and a history (The Loss of El Dorado). In chapter 4 the readers are volunteers who took part in a research project aimed at finding out more about readers' initial orientations towards literary texts, and about reading strategies for different genres. Reviewers of The Mimic Men and The Loss of El Dorado form the second group of readers (chapter 5) and the two sets of reviews are analysed for evidence of centrifugal and centripetal reading. In chapter 6 the readers are academic critics and the materials are longer critical texts. Chapters 5 and 6 also raise questions about literary criticism as an institution, and the influence of interpretive communities. In chapter 7 the centrifugal/centripetal theory is used to produce a reading of The Enigma of Arrival (1987), a novel which hovers on the borderline of nonfiction. Possibilities for further research are outlined briefly in the conclusion.

description: Motivated by the discovery that the eighth root of the theta series of the E_8 lattice and the 24th root of the theta series of the Leech lattice both have integer coefficients, we investigate the question of when an arbitrary element f in R (where R = 1 + xZ[[x]]) can be written as f = g^n for g in R, n >= 2. Let P_n := {g^n : g in R} and let mu_n := n Product_{p|n} p. We show among other things that (i) for f in R, f in P_n <=> f mod mu_n in P_n, and (ii) if f in P_n, there is a unique g in P_n with coefficients mod mu_n/n such that f == g^n (mod mu_n). In particular, if f == 1 (mod mu_n) then f in P_n. The latter assertion implies that the theta series of any extremal even unimodular lattice in R^n (e.g. E_8 in R^8) is in P_n if n is of the form 2^i 3^j 5^k (i >= 3). There do not seem to be any exact analogues for codes, although we show that the weight enumerator of the r-th order Reed-Muller code of length 2^m is in P_{2^r}. We give a number of other results and conjectures, and establish a conjecture of Paul D. Hanna that there is a unique element f in P_n (n != 2) with coefficients restricted to the set {1, 2, ..., n}.

title: Representing the user: a sociological study of the discourse of human computer interaction
Creators: name: Cooper, Geoff
Publisher: name: The Open University
Year: 1991

description: The discipline of Human Computer Interaction (HCI) was established in the early 1980's on the foundations of cognitive psychology, computer science and ergonomics. In recent years however, claims have been made for the relevance of forms of sociology to this avowedly multidisciplinary field, and a number of sociologists have attempted to contribute to the general enterprise of developing a deeper understanding of the computer user and thereby informing, and improving, software design. This thesis is, in one sense, a continuation of this emerging body of work. However, my contention is that little, if any, critical attention has been given within this work to questions that would seem to be of fundamental importance to attempts at collaboration between disciplines: how is the disciplinary organization of knowledge to be understood, and more specifically, can HCI be adequately described in the simple pluralist terms in which it tends to characterise itself? The primary focus then is on the discipline of HCI. Utilising a theoretical model which considers disciplines as distinctive discourses which constitute their own domains of objects, I analyse the discourse and practice of HCI in order to explicate some of its underlying premises and assumptions, and to argue that it has, unavoidably, set many of the parameters within which contributing disciplines must operate. Texts, audio and video tapes, and ethnographic observation of instances of HCI practice form the empirical basis of the thesis. In addition, an analysis of some recorded human-computer interactions, which like the study as a whole, exemplifies an approach that differs from the prevailing sociological models within the field, is used to support the argument.

description: Past planetary missions have been broad and detailed for Gas Giants, compared to flyby missions for Ice Giants. Presently, a mission to Neptune using electrodynamic tethers is under consideration due to the ability of tethers to provide free propulsion and power for orbital insertion as well as additional exploratory maneuvering --- providing more mission capability than a standard orbiter mission. Tether operation depends on plasma density and magnetic field $\mathbf{B}$, though tethers can deal with ill-defined density profiles, with the anodic segment self-adjusting to accommodate densities. Planetary magnetic fields are due to currents in some small volume inside the planet, magnetic-moment vector, and typically a dipole law approximation --- which describes the field outside. When compared with Saturn and Jupiter, the Neptunian magnetic structure is significantly more complex: the dipole is located below the equatorial plane, is highly offset from the planet center, and at large tilt with its rotation axis. Lorentz-drag work decreases quickly with distance, thus requiring spacecraft periapsis at capture close to the planet and allowing the large offset to make capture efficiency (spacecraft-to-tether mass ratio) well above a no-offset case. The S/C might optimally reach periapsis when crossing the meridian plane of the dipole, with the S/C facing it; this convenient synchronism is eased by Neptune rotating little during capture. Calculations yield maximum efficiency of approximately 12, whereas a $10^{\circ}$ meridian error would reduce efficiency by about 6%. Efficiency results suggest new calculations should be made to fully include Neptunian rotation and consider detailed dipole and quadrupole corrections.

description: We present the general rules for double-Reggeon production of objects with different spins and parities. The existing experimental information on resonance production in these central exclusive diffractive processes is discussed. The absorptive corrections are calculated and found to depend strongly on the quantum numbers of the produced states. The central exclusive diffractive production of 0^+ and 0^- Higgs bosons is studied as an illustrative topical example of the use of the general rules. The signal for diffractive 0^+ and 0^- Higgs production at the LHC is evaluated using, as an example, the minimal supersymmetric model, with large tan(beta).

description: The aim of the study was to identify regions with the greatest potential for the production of organic food, which is consistent with the concept of the bio-economy. The main objective of the method of research was to bring all of examined characteristics to comparable size in the range [-1; 1] (the standardised parameters). Then the standardized parameters have been summarized for all three characteristics in order to determine an aggregate measure. This way the data, allowing to compare the provinces with respect to all three features together, have been obtained. The voivodships with the greatest potential to produce organic food are the following: Zachodniopomorskie, Warmińsko-Mazurskie, Mazowieckie, Podlaskie, Lubelskie and Wielkopolskie. All these provinces in the last considered years were in the forefront in terms of area of ecological farmland, number of eco-farms, or/and the number of the eco-processing plants.

description: Dynamic routing occurs when customers are not known in advance, e.g. for real-time routing. Two heuristics are proposed that solve the balanced dynamic multiple travelling salesmen problem (BD-mTSP). These heuristics represent operational (tactical) tools for dynamic (online, real-time) routing. Several types and scopes of dynamics are proposed. Particular attention is given to sequential dynamics. The balanced dynamic closest vehicle heuristic (BD-CVH) and the balanced dynamic assignment vehicle heuristic (BD-AVH) are applied to this type of dynamics. The algorithms are applied to a wide range of test instances. Taxi services and palette transfers in warehouses demonstrate how to use the BD-mTSP algorithms in real-world scenarios. Continuous approximation models for the BD-mTSP's are derived and serve as strategic tools for dynamic routing. The models express route lengths using vehicles, customers, and dynamic scopes without the need of running an algorithm. A machine learning approach was used to obtain regression models. The mean absolute percentage error of two of these models is below 3%.

description: In the recent years, goose meat had a constantly decreasing proportion of the world’s poultry production. However, a significant amount of goose meat is produced mainly in Central Europe and Southeastern Asia. During the last decade, production greatly increased in these areas and also worldwide. China has a leading role in the world’s goose meat production. In Europe, the most significant goose meat producers are Hungary and Poland, the latter of which could greatly improve the volume of production in the recent years, thereby representing an increasingly growing competitor for Hungary. This study illustrates the international circumstances of goose production, as well as the tendencies of production and trade. In addition, RCA indexes were used to examine the comparative advantages of goose meat and meat products in the world waterfowl market in the case of the most significant producers of Europe – Hungary and Poland. Consequently, it can be concluded that the two main exporting countries have different, but significant comparative advantages in terms of various meat products.

While in the case of a constant electric field strength expectation value the static potential remains Coulombic, in the case of a constant magnetic field strength the potential energy is the sum of a Yukawa and a linear potentials, leading to the confinement of static charges.

In our main result we show that if the process has summable memory decay, then the associated filtration is standard. We prove it by coupling techniques. For a process whose associated filtration is standard, we construct a product type filtration extending it, based upon the usual couplings and the Vershik's criterion for standardness.

description: We describe a faster and more accurate algorithm for computing the statistical mechanics of DNA denaturation according to the Poland-Scheraga type. Nearest neighbor thermodynamics is included in a complete and general way. The algorithm represents an optimization with respect to algorithmic complexity of the partition function algorithm of Yeramian et al.: We reduce the computation time for a base-pairing probability profile from O(N2) to O(N). This speed-up comes in addition to the speed-up due to a multiexponential approximation of the loop entropy factor as introduced by Fixman and Freire. The speed-up, however, is independent of the multiexponential approximation and reduces time from O(N3) to O(N2) in the exact case. In addition to calculating the standard base-pairing probability profiles, we propose to use the algorithm to calculate various other probabilities (loops, helices, tails) for a more direct view of the melting regions and their positions and sizes.

On the Formation and Evolution of Stellar Bars in Galaxies

description: We have done a detailed study on the structural and kinematical properties of lenticular and early- and late-type spiral galaxies with bars, aiming to explore the formation and evolution processes of stellar bars in galaxies, and their implications on the global formation and evolution of galaxies. Using spectra obtained along the major and minor axes of the bars in a sample of 14 galaxies, we have determined the stellar velocity distribution in the bars' vertical axis. With these data, it was possible to develop a diagnostic tool that allows one to estimate the ages of bars. Through realistic N-body simulations, we have studied the necessary conditions to the formation of bars in galaxies, as well as the time scale involved in the processes which give bars an important vertical structure. Finally, using optical and near-infrared imaging, we have performed a detailed galaxy structural analysis. Among the main results obtained, we point out: (i) there are vertically thin and thick bars and this difference is caused by a difference in the ages of the bars; (ii) the bar thickening process, as we have determined, is slow (5-10 Gyr); (iii) the current scenario for bar formation is not able to explain naturally the existence of bars in galaxies which are kinematically hot and have prominent bulges; (iv) we suggest a new mechanism for bar formation in galaxies, which can account for the serious drawbacks confronted in the current scenario; (v) bulges in lenticular and in spiral galaxies are, at least partially, formed through the secular evolutionary processes in bars; (vi) during its evolution, a bar grows stronger by capturing stars from the disk, which becomes fainter, in agreement with recent numerical and analytical results.

description: Methane-related carbonates from Hydrate Ridge typically show several macroscopically distinguishable mineral phases, namely whitish aragonite, lucent aragonite, and gray micrite. The relationship of these phases to particular microorganisms or biogeochemical processes is as yet unclear. We used a miniaturized biomarker technique on mg samples, combined with factor analysis and subsequent electron microprobe analysis, to study lipid biomarkers and chemical compositions of the individual phases. This allows us to identify particular mechanisms involved in the formation of the different carbonate precipitates. Our combined analysis of biomarkers and petrographic traits shows that most of the lipids related to the anaerobic oxidation of methane (>90% by weight) are concentrated within only a minor compartment ( 20% by volume) of the Hydrate Ridge carbonates, the whitish aragonite. The patterns indicate that the whitish aragonite represents fossilized biofilms of methanotrophic consortia containing mainly archaea of the ANME-2 group and sulfate reducing bacteria, whereas the precipitation of the lucent aragonite may have lacked the immediate proximity of microorganisms during formation. By contrast, the gray micrite formed by incorporation of allochthonous organic and inorganic matter during carbonate precipitation induced by the anaerobic oxidation of methane involving ANME-1 archaea.

Year: 2022

description: This article introduces ‘existence theory’ as a new approach to sociological theory and research. Existence theory starts from the assumption that people organise their lives around a limited set of existential milestones. Cultural expectations are such that without the accomplishment of those milestones, individuals may experience their lives as incomplete. Examples of milestones can include the attainment of formal education, a lasting partnership and the creation of a family, but in general the milestones which are important to individuals and their precise articulation will depend on a variety of cultural and structural factors. The achievement of existential milestones often depends on that of other existential milestones, thereby producing what we call an ‘existential ladder’. The article also elaborates on the significance of ‘existential urgency’ in that, due to a variety of factors (some biological, some cultural and structural), there are time limits on when certain existential milestones ought to be achieved by. In contemporary society, we note that individuals seem to have more choice about which milestones are important to them and when they can be achieved, although we emphasise that this flexibility is unevenly distributed. This then provides a steppingstone towards an elaboration of the power dynamics and inequalities underlying both the experience and the achievement of existential milestones. Finally, this paper shows how existence theory helps to reflect on a variety of social phenomena of contemporary significance: populism in politics, forced migration, and the coronavirus pandemic.
title: The teacher appraisal interview

Publisher: name: The Open University
Year: 1991

description: Teacher appraisal is one of the key educational issues of the 1980s and 1990s. Developments have been-taking place at both national and local levels, and in the near future, many schools will be obliged to adopt some form of appraisal system. In setting the context for this research, attention is drawn to the purposes and types of appraisal, its major benefits and drawbacks, and the common features of existing schemes. Most teacher appraisal schemes maýe the appraisal "interview" the focal activity, and therefore the effectiveness of the system, is dependent upon the quality of the interaction during the interview itself. Thus, the central aim of this research is to find out more about what goes on in such meetings. In one school eleven case-study appraisal interviews were audio-taped, and intensive analysis of both "content" and "process" was applied. The methodology employed is primarily qualitative and interpretive in nature. Each interview is described in detail, making extensive use of quotations where necessary. The evaluation of each encounter provides valuable insights into the behaviour of participants. Semi-structured interviews with staff from the study school afford additional data. A number of generalities and issues emerge, in relation to both interview content and process. The results are enhanced by making use of certain theoretical concepts from the science of social psychology, including role theory, social psychological orientations, and interactionist perspectives. The implications of this research are considered, in particular the need to train staff in the skills of appraisal interviewing. The characteristics of 'good practice' in a teacher appraisal interview are also discussed. It is concluded that the behaviour of participants in a teacher appraisal interview is a function of role, relationship, personality, and the intricacies of transactional processes. A dramaturgical perspective provides an appropriate language for describing typical interview behaviour. A typology of teacher appraisal interviews is also developed.

It is only in a few decays with excited vector mesons in the final state that measurable TP's may be obtained. On the other hand, TP's in models beyond the SM can be large, and hence TP correlations are excellent probes of new physics.

The effects of a single biosolids application on soil physical properties in three forage production systems in the southern interior of British Columbia

Year: 2011

description: The Greater Vancouver Regional District applies about 15,000 dry tonnes of biosolids per year to various types of land in British Columbia (BC) in an effort to divert biosolids from landfilling, incineration, and ocean disposal. The effects of biosolids (20, and 60 Mg ha⁻¹) and chemical fertilizer on aggregate stability, bulk density, aeration porosity, total C and N of stable aggregates, and the hydrolysis of fluorescein diacetate (FDA) in aggregates> 2 mm were investigated five years after soil application in three common forage production systems (crested wheatgrass = CW, native range = NR, and irrigated alfalfa = IA) in the southern interior of BC. At each of the three sites, the experiment was laid out in 2001 in a randomized block design with four treatments replicated over four blocks. Soil samples were collected during spring, summer, and fall 2005 and 2006. At the CW site, biosolids at 60 Mg ha⁻¹ increased the stability and proportion of soil aggregates> 1 mm, the concentration of C and N in aggregates, and the hydrolysis of FDA. On the NR site, there were no differences in the mean weight diameter (MWD) or the proportion of stable aggregates> 1 mm from either biosolids rates, yet together the biosolids treatments were greater from the control or fertilizer treatments during every sample period in 2006. Biosolids applied at 20 Mg ha⁻¹ significantly increased total C and N of stable aggregates and reduced bulk density relative to all other treatments. At the IA site, biosolids applied at 60 Mg ha⁻¹ decreased bulk density in 2005 and 2006, relative to the control and the fertilizer treatment decreased aeration porosity and the concentration of C in aggregates. Our data showed that, land applied biosolids to these common forage production systems in the southern interior of BC enhanced aggregate stability and total C of stable aggregates. The majority of improvements to soil properties at the CW and IA sites came from biosolids applied at 60 Mg ha⁻¹, while the greatest improvements to soil properties at the NR site were from the 20 Mg ha⁻¹ biosolids treatment. This is thought to be due to greater site productivity (above and below ground) from the 60 Mg ha⁻¹ treatment at the CW and IA sites, as compared to the NR site where the 20 Mg ha⁻¹ biosolids treatment decreased bulk density and increased the concentration of C and N among stable aggregates, relative to all other treatments.

description: As a generalization of DHR analysis, the superselection sectors are studied in the case of absence of the spectrum condition for the reference representation. Considered a net of local observables in the 4-dimensional Minkowski spacetime, we show that it is possible to associate to a set of representations, that are local excitations of a reference one fulfilling Haag duality, a symmetric tensor $\mathrm{C}^*$-category $\Bim$ of bimodules of the net, with subobjects and direct sums. The existence of conjugates is studied introducing an equivalent formulation of the theory in terms of the presheaf associated with the observable net. This allows us to find, under the assumption that the local algebras in the reference representation are properly infinite, necessary and sufficient conditions for the existence of conjugates. Moreover, we present several results that suggest how the mentioned assumption on the reference representation can be considered essential also in the case of theories in curved spacetimes.

We use a hidden landscape function $u$, defined as the solution of an inhomogeneous boundary problem with uniform right-hand side for $H$, to predict the location of the localized eigenfunctions of $H$. Explicit bounds on the exponential decay of Agmon type for low energy modes are obtained. This extends the recent work of Agmon type of localization in [5] for $\mathbb{R}^d$ to a tight-binding Hamiltonian on $\mathbb{Z}^d$ lattice. Contrary to the continuous case, high energy modes are as localized as the low energy ones in discrete lattices. We show that exponential decay estimates of Agmon type also appear near the top of the spectrum, where the location of the localized eigenfunctions is predicted by a different landscape function. Our results are deterministic and are independent of the size of the cube. We also provide numerical experiments to confirm the conditional results effectively, for some random potentials.

description: We show that in a locally lambda-presentable category, every lambda(m)-injectivity class (i.e., the class of all the objects injective with respect to some class of lambda-presentable morphisms) is a weakly reflective subcategory determined by a functorial weak factorization system cofibrantly generated by a class of lambda-presentable morphisms. This was known for small-injectivity classes, and referred to as the "small object argument". An analogous result is obtained for orthogonality classes and factorization systems, where lambda-filtered colimits play the role of the transfinite compositions in the injectivity case. Lambda-presentable morphisms are also used to organize and clarify some related results (and their proofs), in particular on the existence of enough injectives (resp. pure-injectives).

title: Theological education and ministerial training for the ordained ministry of the Church of England 1800 - 1850
Creators: name: Park, Trevor
Publisher: name: The Open University

description: There were no establishments of higher education in England and Wales in 1800 where an Anglican ordinand could receive a professional training to prepare him for his future parochial ministry, Most men who took Holy Orders in the Church of England had no more theological education than any other graduate of the two English universities. If the candidate had been educated at Oxford, his degree was largely in classical studies, if at Cambridge in mathematics. By 1850 the situation had changed radically. In response to mounting criticism there had been some modest reforms in the two ancient universities, most notably the establishment at Oxford in 1842 of two new regius professorships in Pastoral Theology and Ecclesiastical History , and at Cambridge the introduction of the Voluntary Theological Examination in 1843. More importantly nine new institutions of higher education which catered for Anglican ordinands had been founded. These were: 1817 St Bees Clerical Institution 1825 C. M. S. Institution, Islington 1827 St David's College, Lampeter 1831 King's College, London 1833 Durham University 1839 Chichester Diocesan Theological College 1840 Wells Diocesan Theological College 1847 St Aidan's College, Birkenhead 1848 St Augustine's Missionary College, Canterbury In addition, the Theological Department of the Queen's College, Birmingham existed in part - it had premises and staff but' no studentsl Two more institutions were under consideration at Cuddesdon (Oxford) and at Lichfield. This study explores why and how this transformation took place in the provision of theological education and ministerial training for the ordained ministry of the Church of England between 1800 - 1850. More particularly it documents who the men were who had the vision and entrepreneural skills to found new colleges and universities$ what the social, political and ecclesiastical factors were which motivated them to undertake this great work, and what influenced the form and ethos of these new institutions. In so doing, it is a record of part of the Church of England's contribution to higher education during that half century.

description: The main objective of the paper was critical assessment of the administrative procedures for applying for funding investments in farms from the “Rural Development Programme” 2014-2020. Public funds should be spent with due diligence. They must be defined clear goals for their spending and proposed appropriate assessment procedures. They should be relatively simple for applying for funding and clear in the evaluation of administrative staff. Analyzed in the article, the administrative requirements of applying for funding and the procedure for assessing the validity of investment activities in the operation “Help in starting a business for young farmers” are complicated, useless, imprecise and inducing farmers to primitive, simple (usually unprogressing) investments.
title: Stress in firefighters: situations, reactions and interactions
Creators: name: Docherty, Robert Walker
Publisher: name: The Open University
Year: 1992

description: A series of studies were carried out to determine how experience and training in firefighters affected their reactions to situations they encountered at work. The first three studies used quantitative and qualitative techniques to identify those situations which firefighters found to be significant to them in terms of varying stressfulness. One of these studies sampled firefighters who attended the Manchester Air Disaster. The final two studies used the situations identified by the initial studies and extended the methodology of Payne, Fineman & Jackson (1982) in the development of a measure of work anxiety within a paradigm of interaction between situations and individual reactions. Evidence for the interactionist position was found in both studies although subject's reactions to situations seemed to be situationally driven. Strength of reactions to situations did reduce over time due to training, experience, occupational group homogeneity and the learning of coping strategies. As a result of these studies an extended model of the interactionist position was proposed as well as some suggestions for future research.

description: Signal processing on directed graphs (digraphs) is problematic, since the graph shift, and thus associated filters, are in general not diagonalizable. Furthermore, the Fourier transform in this case is now obtained from the Jordan decomposition, which may not be computable at all for large graphs. We propose a novel and general solution for this problem based on matrix perturbation theory: We design an algorithm that adds a small number of edges to a given digraph to destroy nontrivial Jordan blocks. The obtained digraph is then diagonalizable and yields, as we show, an approximate eigenbasis and Fourier transform for the original digraph. We explain why and how this construction can be viewed as generalized form of boundary conditions, a common practice in signal processing. Our experiments with random and real world graphs show that we can scale to graphs with a few thousands nodes, and obtain Fourier transforms that are close to orthogonal while still diagonalizing an intuitive notion of convolution. Our method works with adjacency and Laplacian shift and can be used as preprocessing step to enable further processing as we show with a prototypical Wiener filter application.

description: The aim of this paper was to present the reserves of labour resources in agriculture on the basis of statistical data from the Central Statistical Office of Poland and indicate the possibilities to use them in rural areas. The paper presents the changes in the structure of agricultural holdings, the level of concentration of the labour resources expressed in number of annual work units (AWU) per 100 ha of agricultural land and the qualifications of farm managers. The paper also investigates the possibilities to utilize the surplus labour force in agriculture in rural areas, stressing the necessity to stop the migration of rural population to urban areas.
title: Britain's new industrial space? A case study of high technology Hertfordshire'
Creators: name: Henry, Nicholas David
Publisher: name: The Open University
Year: 1991

description: The suggestion is now widespread that fundamental changes within the advanced Western economies are part of the transition to a new era of capitalist development. The geographical repercussions of this change, the form of the new geography of production, has become the subject of much conjecture. The question has become one of explaining how the present period of economic restructuring is being translated into a period of spatial restructuring. A key element of such theories of change has been the "high technologies", defined both as a process of change and as the basis of new industries encapsulating new forms of production. Indeed, for the proponents of the New Industrial Spaces theory, the rise of "high technology" industry is the harbinger of structural change and its spatial development indicative of the new geography of production we may expect throughout North America and Western Europe (Scott and Storper, 1986; Scott, 1988a; 1988b). This thesis outlines a theoretical and empirical investigation of the New Industrial Spaces theory, an investigation framed by the principal claim of the theory to explain the processes structuring the emergent geography of production. Firstly, a critique of this claim argues that whilst the explanation provided (based on transaction costs) is plausible, it rests upon a particular and deficient conceptualisation of the firm. Secondly, allowing for such reservations, it is argued that the explanation of the New Industrial Spaces' theorists has yet to be shown as empirically valid. Thus, in the search for this evidence, an empirical investigation of Britain's own prominent candidate for the title New Industrial Space, namely "high technology Hertfordshire", is undertaken. Whilst this empirical investigation provides evidence for the New Industrial Spaces theory, it also highlights the theory's failure to explain fully the growth of "high technology Hertfordshire". In contrast, the thesis develops an alternative conceptualisation of contemporary agglomerations of production.

description: In the present work, we adopt a relativistic constituent quark model to depict the charmed strange meson spectroscopy, in which $D_{s0}(2317)$ and $D_{s1}(2460)$ are considered as the $1^3P_0$ and $1P_1^\prime$ charmed strange mesons, respectively. By using the wave function obtained from the relativistic quark model, we further investigate the electric transitions between charmed strange mesons. We find the long wave length approximation is reasonable for the charmed strange meson radiative decay by comparing the results with different approximations. The estimated partial widths are all safely under the upper limits of the experimental data. Moreover, we find the branching ratio of $D_{s1}(2536) \to D_s^\ast γ/D_s γ$ are large enough to be detected, which could be searched by further experiments in Belle II and LHCb.
