In recent years the field of communication has been experiencing a movement toward newer non-tradtional approaches to the study of communication and information. Among these newer approaches is a growing body of research that focuses on interpretive behavior in the communication process.
Brenda Dervin's Sense-Making model of communication/information has been the most widely used interpretive theory of information to date. Sense-Making focuses primarily upon the role of the receiver in the communication process and how individuals construct meaning in specific situations. As a result, Sense-Making has not attended adequately to larger shared frameworks of meaning and the effects that they have upon information seeking and use.
It is the purpose of this thesis to strengthen Dervin's theory of Sense-Making by gaining a deeper view of the individual in the construction process and yet broadening the meaning making context to include structural concerns. The work of William Perry on cognitive and ethical development will be examined and applied to Sense-Making theory and data to provide a more in-depth understanding of how individuals construct meaning and use information. As a framework for examining shared structures of meaning, James Fowler's theory of faith development has also been applied to Sense-Making theory and data with particular emphasis on relational aspects. These theories are applied to Sense-Making in an effort to develop a more complete view of the individual in the communication process.

Whereas ten years ago most SLA researchers assumed a rationalist, "scientific" approach to theory construction, recently, growing numbers have adopted relativist positions that strongly criticise the methods, and authority of the rationalist/empiricist paradigm. Apart from the problem of research methodology, other problems make progress in the construction of a theory of SLA difficult: the proliferation of theories, contradictions among them, and, most important of all, confusion about the domain and objectives of a theory of SLA. This thesis addresses the problems outlined above by returning to first principles and asking what it is that we can know about the world, whether there is any such thing as reliable knowledge, what is special about scientific methodology, and what the best way of tackling the complex task of explaining SLA might be. While previous surveys of SLA research exist, no previous attempt has been made to examine SLA research in terms of its epistemological underpinnings and its relation to scientific method, or to evaluate different research programmes and putative theories in terms of how they form part of, and contribute towards, a rational, scientific explanation of the phenomena of SLA. Having outlined basic terms and the problems to be dealt with, I give a brief history of scientific method and explain the objections to a rationalist methodology raised by various relativists. I then attempt to defend rationality against relativists' attacks and suggest criteria that can guide a rationalist research programme in SLA. The questions of the domain of SLA theories, what counts as an explanation, and different theory types are examined. Having suggested guidelines for a rationalist approach to SLA theory construction, I examine different approaches to SLA in the history of SLA, assessing them in terms of the guidelines. Finally I suggest what the domain of a theory of SLA should be and discuss to what extent theories to date offer a satisfactory explanation of the phenomena within that domain.

My supervisors Ian Chiswell and Thomas M¨uller have found a new class of groups of functions defined on intervals of the real line, with multiplication defined by analogy with multiplication in free groups. I have extended this idea to functions defined on a densely ordered abelian group. This doesn’t give rise to a class of groups straight away, but using the idea of exponentiation from a paper by Myasnikov, Remeslennikov and Serbin, I have formed another class of groups, in which each group contains a subgroup isomorphic to one of Chiswell and M¨uller’s groups. After the introduction, the second chapter defines the set that contains the group and describes the multiplication for elements within the set. In chapter three I define exponentiation, which leads on to chapter four, in which I describe how it is used to find my groups. Then in chapter five I describe the structure of the centralisers of certain elements within the groups.

Modified Fourier expansions present an alternative to more standard algorithms for the approximation of nonperiodic functions in bounded domains. This thesis addresses the theory of such expansions, their effective construction and computation, and their application to the numerical solution of partial differential equations. As the name indicates, modified Fourier expansions are closely related to classical Fourier series. The latter are naturally defined in the d-variate cube, and, in an analogous fashion, we primarily study modified Fourier expansions in this domain. However, whilst Fourier coefficients are commonly computed with the Fast Fourier Transform (FFT), we use modern numerical quadratures instead. In contrast to the FFT, such schemes are adaptive, leading to great potential savings in computational cost. Standard algorithms for the approximation of nonperiodic functions in

Pełny tekst źródłaStreszczenie:
Building contractors are often commissioned using unit price based contracts. They, nevertheless, often compete on the basis of their overall project bids and yet are paid on the basis of these projectsâ constituent item prices. If a contractor decides these prices by way of applying an uneven mark-up to their estimates of their costs, this is known as unbalanced bidding. This research provides proof and explanation that different item pricing scenarios produce different levels of reward for a contractor, whilst exposing them to different degrees of risk. The theory describes the three identified sources of these rewards as well as provides the first explanation of the risks. It has identified the three types of risk involved and provides a model by which both the rewards as well as these risks can now be measured given any item pricing scenario. The research has included a study of the mainstream microeconomic techniques of Modern Portfolio Theory, Value-at-Risk, as well as Cumulative Prospect Theory that are all suited to making decisions that involve trading-off prospective rewards against risk. These techniques are then incorporated into a model that serves to identify the one item pricing combination that will produce the optimum value of utility as will be best suited to a contractorâs risk profile. The research has included the development of software written especially for this purpose in Java so that this theory could be tested on a hypothetical project. A test produced an improvement of more than 150% on the present-value worth of the contractorâs profit from this project, if they apply this model compared to if they instead price the project in a balanced manner.

Pełny tekst źródłaStreszczenie:
La procedure standard pour construire une courbe de puissance est la norme lEC. Toutefois,
ce modele contient quelques faiblesses. Une de ses faiblesses est le fait de moyenner les
puissances, ce qui engendre des erreurs puisque les puissances obtenues, sur la courbe de
puissance, sont grandement influencees par I'intensite de turbulence de la vitesse du vent. De
plus, cette norme pent demander beaucoup de temps pour evaluer 1'influence de divers
parametres sur une eolienne. La solution proposee dans ce memoire est d'implementer une
nouvelle methode, en suivant la theorie de Markov, pour calculer les courbes de puissance.
Cette methode calcule la puissance stationnaire avec une approche stochastique, laquelle est
plus precise et s'effectue en un plus court laps de temps. II arrive aussi que le calcul d'une
courbe de puissance puisse etre impossible a effectuer avec I'anemometre a la tour
meteorologique, il faut done creer une fonction de transfert pour I'implementer a
I'anemometre a la nacelle de I'eolienne.
L'objectif final de ce memoire est de creer un programme qui va constmire une courbe de
puissance, avec I'anemometre a la nacelle, en suivant la theorie de Markov, tout en evaluant
et opfimisant I'influence de divers parametres. Finalement, un autre objectif est I'analyse du
temps minimum requis avec ce nouveau modele pour constmire une courbe de puissance.
Bien que les resultats obtenus ne soient pas stables, ni parfait, ce memoire propose la
mediane pour calculer le moment conditionnel, puisque les resultats sont moins affectes par
I'intensite de turbulence. Par la suite, il propose aussi de moyenner les vitesses du vent sur
une periode de deux minutes, lorsque la vitesse du vent est lue sur I'anemometre a la nacelle,
afin d'eliminer les fluctuations rapide du vent causees par le passage des pales de I'eolierme.
Cependant, le temps necessaire a la construction d'une courbe de puissance en suivant la
theorie de Markov n'est pas affectee par les donnees moyennces a differents intervalles de
temps. Par contre, cette nouvelle methode pent constmire une courbe de puissance en un
temps plus rapide que la norme lEC.
De plus amples ameliorations doivent etre effectue dans le programme qui constmit la courbe
de puissance avec Markov. En fait, I'amelioration du programme permettrait d'obtenir des
resultats plus stables, et done plus precis. Par le fait meme, cette amelioration pourrait faire
en sorte d'effectuer une courbe de puissance en un temps plus court. La premiere
recommandation est de verifier I'impact du filtrage pour la posifion du rotor, avec un plus
grand nombre d'eoliennes. La deuxieme recommandation est de corriger I'apparition du
deuxieme minimum. Une methode pour le corriger est d'optimiser I'intervalle du temps de

This thesis explains the "systematic" refinement of Kenneth Burke's theoretical process through his development of a theological paradigm for the dramatistic vocabulary. It describes the merging metaphysical and dialectical issues in Burke's critical thought and locates a theoretical shift in A Grammar of Motives, where Burke posits the prototype for his key term, "act." The study then interprets the formal treatment of the prototype in The Rhetoric of Religion: Studies in Logology, and demonstrates how the derived paradigm maintains and advances the convergence of metaphysics and dialectics, and how it reestablishes the interaction between language structure and usage in two types of definition or explanation (temporal-logical, narrative-tautological). This thesis also describes the purpose and functional range of Logology.

The growing interest in volatility trading, by many types of financial institutions, has led to a recent surge of interest amongst academics. Variance swaps are the most popular pure volatility trade derivatives, so understanding them is of imperative importance. So therefore, we provide an extensive empirical work in variance swaps spotting trading patterns via using all of the most widely known volatility indices. Additionally, we perform a comprehensive distribution fitting exercise to the variance swap returns, which provides in sights to their accurate modelling. We also show that the 'model-free' volatility index formula, which the exchanges base their volatility indices upon, is actually model-dependent. The main theoretical contribution of this thesis lies in the derivation of a completely model-free risk-neutral moment generating function which is not constrained by the usual underlying and volatility dynamics assumptions. Our model-free risk-neutral moment generating function can generate higher moment indices for assets which are traded or not. Extending the literature beyond the second moment, we derive formulae for model- free volatility, skewness and kurtosis based on our moment generating function. The estimation of these formulae is free from the problems and constraints that the calibration techniques entail. We also test the numerical procedures that are used by the exchanges, finding that they can be considerably improved. A time period of more than 16 years of FTSE 100 options provides a challenging environment in which to implement our theoretical results. Important observations of these data help the adjustment of the model-free formulae to minimise any data related errors, particularly those relating to 'cabinet' options. The absence of a volatility index in the British market inspired the construction of the VFTSE, the first volatility index on the FTSE 100 index. We show that the standard methodology consistently overestimates volatility and that the standard distributions used for model-free volatility modelling are incorrect. Viable alternatives are proposed. Following this, we present for the first time in the literature, term structure of skewness and excess kurtosis time series indices, the SFTSE and KFTSE indices. Using those moment indices, we build and analyse FTSE 100 forward densities using four different methodologies. Our results have important implications for VaR analysis, volatility trading and risk management. Finally, we discuss an options trading application of our moment indices, using FTSE 100 forward densities to spot mispriced FTSE 100 options.

Everitt, Mark Stanley. "Construction, theory and simulation of cavity QED systems". Thesis, University of Leeds, 2009. http://etheses.whiterose.ac.uk/2786/.
Pełny tekst źródłaStreszczenie:
The microscopically pumped maser, or micromaser is a cavity QED experiment intended to be a physical realisation of the Jaynes-Cummings model of a single two-level atom interacting with a single mode electromagnetic field. This is the simplest model that describes the interaction between light and matter, yet it predicts behaviour unexpected from semiclassical models, such as the revival of Rabi oscillations of an atom interacting with an initially coherent field and non-monotonic linewidth as a function of pumping. The micromaser at the University of Leeds consists of a high quality superconducting microwave cavity designed to be resonant with the transition between two specific Rydberg states of rubidium. These two states behave like an ideal two level atom, and couple strongly to the cavity field due to a large dipole moment. These Rydberg atoms are passed through the cavity in a rarified beam such that in most instances when there is an atom in the cavity, there will only be one, closely approximating the Jaynes-Cummings model. I present experimental work on the build phase of the micromaser. Specifically I routed all of the wiring and microwave lines in the cryostat that contains the micromaser, and designed mounts for various components. I also designed several testing methods for probing high quality microwave cavity resonances and quality factors which are presented. Using the Jaynes-Cummings model as a prototype, I demonstrate how extensions to the model can be used to construct universal quantum logic gates that operate on photonic qubits in a multi-mode cavity. This could be realised in a micromaser with a multi-mode cavity. Conversely, I demonstrate that by using atoms as qubits, detuned cavities can be used to generate entangled resources such as the Greenberger-Horne-Zeilinger state, the W state, and graph states of atoms. I show that single qubit rotations on Rydberg atom qubits have already been experimentally demonstrated so that in combination these entangled resources are useful for quantum metrology, quantum computation and even tests of quantum gravity.

This thesis splits into two parts. In the first part we introduce a bosonic construction of the ten-dimensional fermionic theories. This construction relies on a consistent truncation procedure which can produce fermions out of bosons. We illustrate this truncation procedure in the case of type II superstring theories, which emerge as the truncation of the 26-dimensional closed bosonic string theory compacified on the weight lattice of E(_8) x E(_8). The same truncation procedure can be applied to the unoriented bosonic string theory compactified on the above lattice and produces the type I superstring theory with the Chan-Paton gauge group reduced from SO(2(^13)) to SO(32). We also demonstrate that the BPS D-branes in Type I theory can be obtained from the bosonic D-branes wrapping on the above lattice by using the technique of Boundary Conformal Field Theory. In the second part, we construct new four-dimensional configurations of oppositely charged static black hole pairs (diholes) which are solutions of the low-energy effective action of string theories. The black holes are extrernal and carry four different charges. We also generalize the dihole solution to a theory which has an arbitrary number of abelian gauge fields and scalars where the diholes are composite objects. We uplift the dihole solutions to higher dimensions in order to describe intersecting brane-anti-brane configurations in string theory. The properties of the strings and membranes stretched between the brane and anti-brane are discussed.

A new high order theory, referred to as the Extended High-Order Sandwich Panel Theory (EHSAPT), was formulated for orthotropic sandwich beams/wide panels with a general layout. This new theory accounts for the axial, transverse normal, and shear rigidity of the core. Validation of the present theory was performed for several structural analysis problems including: static loading, static instability (global buckling and wrinkling), free vibrations (natural frequencies), and dynamic loading (blast and impact). The accuracy of the theory was assessed by comparison with elasticity solutions and with experiment. It is shown that this new theory has superior accuracy over other available computational models, especially for sandwich beams/wide panel configurations with stiffer cores.

It is often very difficult, particularly in higher dimensions, to find a good multivariate model that describes both marginal behavior and dependence structure of data efficiently. The copula approach to multivariate models has been found to fit this purpose particularly well, and since it is a relatively new concept in statistical modeling, it is under frequent development. In this thesis we focus on the decomposition of a multivariate model into pairwise copulas rather than the usual multivariate copula approach. We account for the theory behind the decomposition of a multivariate model into pairwise copulas, and apply the theory on both daily and intra day financial returns. The results are compared with the usual multivariate copula approach, and problems applying the theory are accounted for. The multivariate copula is rejected in favor of the pairwise decomposed model on daily returns with a level of significance less than 1%, while our decomposed models on intra day data does not lead to a rejection of the models with multivariate copulas. On daily returns a pairwise decomposition with Student copulas is preferable to multivariate copulas, while the decomposed models on intra day data need more development before outperforming multivariate copulas.

Thesis: M. Eng., Massachusetts Institute of Technology, Department of Civil and Environmental Engineering, 2015.Cataloged from PDF version of thesis.
Includes bibliographical references (page 105).
The Collier Memorial is a vaulted stone structure that was built on the campus of the Massachusetts Institute of Technology during the fall of 2014 and the spring of 2015. In the course of the last century, structural engineers have almost fully abandoned the practice of masonry vaulting. The the Collier Memorial is a particularly interesting structure, because it spans not only space but also time, to an age that appreciated permanence in structure, an ideal befitting a memorial. This study's main goal was to equip the construction team with real-time validation of the Collier Memorial's performance during the most critical phase of construction-the lowering of the vault. This was accomplished by using a simple analytical approach to predict how loads and deformations would evolve at every stage of the lowering process. Using the lower-bound theorem of plastic theory, thrust line analysis was performed assuming global equilibrium was satisfied among the five legs. Jack loads were predicted using simple two-dimensional equilibrium while the deformations were predicted considering the structure to behave as a series of straight elastic bars that are oriented along the line of thrust and experience an axial force equal to the assumed thrust force. By choosing to predict the performance in addition to monitoring it, the team had the opportunity to test how their understanding of equilibrium applied to the structural performance of a modem masonry structure. Working with an accurate prediction of the performance, the hope was that the structure would carry as much of its own weight as possible before being grouted, so that the small amount of reinforcing steel would be only minimally engaged and thus pose a minimal threat to fracturing the stones in the future. By comparing the theoretical results and physical monitoring data, it was found that there was very little construction error, and this condition laid the path for shedding 96% of the vault load in the scaffolding and developing joint openings less than 1mm prior to grouting. Ultimately, this study demonstrates that simple hand calculations are capable of producing accurate solutions to complex problems. Given these results, the future of masonry vaulting could be brighter than its more recent past, as the legitimacy of its structural and historical merits outweigh any belief that this type of construction has somehow become inferior due to modern advancements.

Statistical predictive validity has regularly been demonstrated for the complex selection procedure by which young high-potential administrative entrants are recruited to the Civil Service. There is, however, a largely unexplored qualitative aspect to recruitment as well. For most successful candidates, taking up appointment as trainee administrators represents a major life-transition - from full-time education to full-time employment. What is that experience like? How do they go about making sense of their new circumstances? Six trainees took part in the enquiry, which centred on a series of interviews carried out over the course of their first year at work. The focus in this ideographic study is on the individual as learner In a natural setting. Analysis of the accounts produced is set in a social cognition framework, and something of the approach of the ethnographer is also brought to bear. Particular attention is paid to the status of narrative as knowledge. A simple model is outlined for narrative-based reflection as a means to development, with the prospect of the individual acting as his or her own mentor in the process.

One of the main research questions in financial mathematics is that of portfolio construction: how should one systematically invest their wealth in a financial market? This problem has been tackled in numerous ways, typically through the modeling of market prices and the optimization of an investment objective. A recent approach to portfolio construction is that offered by Stochastic Portfolio Theory, in which a relatively general market model is assumed, and the portfolio selection criterion is to outperform a benchmark with probability one. In order to achieve this, Robert Fernholz developed the method of functional generation, which allows one to explicitly construct and study portfolios that depend deterministically on the currently observable prices. The typical example of such a strategy is the diversity-weighted portfolio, which we extend in the first chapter of this work with a negative-parameter variation. We show that several modifications of this portfolio outperform the market index in theory, under certain assumptions on the market, and we perform an empirical study that confirms this. In our second chapter, we develop a data-driven portfolio construction method that goes beyond functional generation, allowing for the inclusion of factors other than current prices. We empirically show that this Bayesian nonparametric approach, which utilizes Gaussian processes, leads to drastically improved performance compared to benchmark portfolios. Next, we establish a formal equivalence between the method of functional generation and the mathematical field of optimal transport. Our results fortify known relations between the two, and extend this connection to additive functional generation, a recent variation of the method. In Chapter 4, we apply our results to derive new properties and characterizations of functionally-generated wealth processes in very general market models. Finally, we develop methods for incorporating defaults into functional generation, improving its real-world implementability.

Construction industry is a one of the most risky sectors due to high level of uncertainties included in the nature of the construction projects. Although there are many reasons, the deficiency of cash is one of the main factors threatening the success of the construction projects and causing business failures. Therefore, an appropriate cash planning technique is necessary for adequate cost control and efficient cash management while considering the risks and uncertainties of the construction projects.
The main objective of this thesis is to develop a realistic, reliable and cost-schedule integrated cash flow modeling technique by using fuzzy set theory for including the uncertainties in project cost and schedule resulting from complex and ambiguous nature of construction works. The linguistic expressions are used for utilizing from human judgment and approximate reasoning ability of users for reflecting their experience into the model to create cash flow scenarios. The uncertain cost and duration estimates gathered from experts are inserted in the model as fuzzy numbers. The model provides the user different net cash flow scenarios with fuzzy formats that are beneficial for foreseeing possible cost and schedule threats to the project during the tender stage. The model is generated in Microsoft Excel 2007 using Visual Basic for applications and the model is applied to a case example.

O objetivo principal deste estudo é identificar na indústria de construção civil como as estratégias das empresas durante o período de 2011 a 2016 afetaram o seu posicionamento e, consequentemente, o seu desempenho. Também são identificadas as principais dimensões estratégicas adotadas pelas firmas que
refletem o modo como elas competem. Por último, é avaliada a presença de grupos estratégicos nesta indústria. A Base de dados utilizada é composta de 15 empresas e contém informações sobre seu comportamento estratégico. São consideradas cinco variáveis estratégicas e sete variáveis de desempenho. Os dados coletados foram analisados utilizando métodos estatísticos multivariados como análise de fatores, análise de cluster e MANOVA. Os resultados obtidos através dessa análise sugerem que as diferenças de desempenho médias dos grupos estratégicos formados podem ser explicadas em função das diferenças
entre as decisões estratégicas de cada empresa da amostra.The main objective of this study is to identify in the construction industry how the strategies of companies during the period from 2011 to 2016 affected their positioning and consequently their performance. It also identifies the main strategic dimensions adopted by firms that reflect how they compete. Finally, the presence of strategic groups in this industry is evaluated. The database used is composed of 15 companies and contains information about their strategic behavior. Five strategic variables and seven performance variables are considered. The data collected were analyzed using multivariate statistical methods such as factor analysis, cluster analysis and MANOVA. The results obtained through this analysis suggest that the average performance differences of the strategic groups formed can be explained by the differences between the strategic decisions of each company in the sample.

The objective of this study was the development of the imaging subsystem of an organ mapping system that would be able to acquire sufficient information for building a 3D cellular level map of a small organ. The imaging subsystem that is presented is a confocal scanning laser microscope arrangement that is versatile and offers a number of different imaging modes, with minimal modifications in the optical configuration, and no need for realignment of optical components.The organ mapping system is a part of a larger project involving the building of a teleoperated microsurgical robot capable of operating on small organs, such as the eye. In this context a second imaging system prototype based again on a scanning laser microscope configuration is presented. The development of this second imaging system is for investigating possible integration of such a device into the surgical microrobot for high resolution image acquisition during operations. The main feature of this system is that the scanning is performed in spherical coordinates; making it suitable and advantageous for imaging organs that exhibit some form of spherical shape, such as the eye.
Before the two imaging systems are presented an overview of the theory governing the operation of confocal microscope arrangements is given, together with a simple model based on geometric optics with Gaussian beam weighting that describes the depth response of a confocal arrangement as a function of the detector size. Finally, a detailed analysis of the error due to refractive index mismatches, that can lead to significant dimensional miscalculations when volumetric imaging is performed with a confocal microscope, is also presented.

We construct the moduli spaces of stable maps, Mg,n(pr, d), via geometric invariant theory (GIT). This construction is only valid over Spec C, but a special case is a GIT presentation of Mg,n, which is valid over any algebraically closed field. Our method follows that of Gieseker in [G] and Swinarski in [Sw2], though our proof that the semistable set is nonempty is different.

Background: The professional development of midwifery in China has been challenged by its marginalised professional status and the medical dominance within midwifery practice in the contemporary maternity care system. There has been growing confusion about, ‘Who the midwife is and what does the midwife do?’ within and outside the profession. The sense of identity crisis for the profession has become particularly salient when Chinese midwifery becomes a sub-branch of the nursing profession during the contemporary period. If, however, we consider the International Confederation of Midwives (ICM) Mission Statement (2008: 32) that midwives are the ‘most appropriate professionals for childbearing women in keeping childbirth normal’, then the focus on a greater understanding of midwives is needed. It is the aim of this research to facilitate this understanding by exploring how hospital-based Chinese midwives construct their professional identity in the contemporary maternity care system and the factors that significantly influence the process. Design and Method: A Constructivist Grounded Theory (CGT) study was conducted to achieve the research aim. A sample of 15 midwives and 5 women participants was recruited between October 2010 and May 2011 from a capital city in one province of China. The accounts from the participants in the form of in-depth individual interviews were digitally recorded and three work journals from midwife participants were also included to facilitate the exploration of the study subject. NVivo 8 was used to assist with data management for the analysis. Findings: Six principle categories were identified: ‘institutional position’; ‘organisational management’; ‘professional discourse’; ‘compromising strategies’; ‘engaging strategies’; and ‘hybrid identity’. The integration of the principle categories has developed the theoretical model ‘navigating the self in maternity care’, which suggests that professional identity construction in midwives is a dynamic process, involving a constant structural and attitudinal interplay between the external (‘obstetric nurse’) and internal (‘professional midwife’) definitions of the midwife. The model indicates that the midwives’ professional identity construction was contextualised in their ‘institutional position’ in the contemporary maternity care system. In everyday practice, midwives experienced identity dissonance in relation to two competing identities: the ‘obstetric nurse’, bound up to the ‘organisational management’ in hospital settings; and the ‘professional midwife’, associated with the ‘professional discourse’ in the midwifery profession. Two types of strategies were identified to reduce the identity dissonance – ‘compromising strategies’ and ‘engaging strategies’ – which resulted in a ‘hybrid identity’, as the construction of professional identity in individual midwives is navigating along an identity continuum with ‘obstetric nurse’ and ‘professional midwife’ at opposing ends. This thesis has expanded on the current theoretical knowledge of identity work by elaborating on the discursive practices professionals employ to legitimate their professional identity and the various strategies individuals use to negotiate their identities at work. It has also extended attention to the influence of institutional forces on professional identity construction. With specific regard to Chinese midwifery, this emerging theoretical model provides a number of possible implications for midwifery practice, education and policy which would facilitate the exploration of effective operational processes for midwives in China to develop professionally.

Ni-Mn-Ga and In-Tl are two examples of shape memory alloys. Their shape memory effect is controlled by the martensitic transformation from the high temperature cubic phase to the low temperature tetragonal phase. Experimentally, it was found that the martensitic transformation, related to the elastic properties, is highly composition-dependent.In order to better understand the phase transition and facilitate the design of new materials with improved shape memory properties, the atomic scale description of the thermophysical properties of these alloys is needed. Therefore, in the presen tthesis, the elastic properties and phase stability of Ni-Mn-Ga and In-Tl shape memory alloys are investigated by the use of first-principles exact muffin-tin orbitals method in combination with the coherent-potential approximation. We present a theoretical description of the equilibrium properties of pure In and standard stoichiometric Ni2MnGa alloy with both cubic and tetragonal structures. In In-Tl alloys, all the calculated composition-dependent thermophysical properties: lattice parameter c/a, tetragonal shear modulus C" = (C11 - C12)/2, energy difference between the austenitic and martensitic phases, as well as electronic structures are shown to be in line with the experimentally observed lowering of the martensitic transition temperature TM with the addition of Tl. For most of the off-stoichiometric Ni2MnGa, the excess atoms of the rich component prefer to occupy the sublattice of the deficient one, except for the Ga-rich alloys, where the excess Ga atoms have strong tendency to take the Mn sublattice irrespective of the Mn occupation. In Ni-Mn-Ga-X (X=Fe, Co, and Cu) quarternary alloys, Fe atom prefers to occupy the Mn and Ni sublattices even in Ga-deficient alloys; Co has strong tendency to occupy the Ni-sublattice in all types of alloys; Cu atoms always occupy the sublattice of the host elements in deficiency. For most of the studied Ni-Mn-Ga and Ni-Mn-Ga-X alloys with stable site-occupations, the shear modulus C" can be considered as a predictor of the composition dependence of TM of the alloys: the alloy with larger C" than that of the perfect Ni2MnGa generally possesses lower TM except for Ni2Mn1+xGa1-x and Ni2Mn1-xGaFex. The failure of C" as a factor of TM in these two types of alloys may be ascribed that the compositiondependentmagnetic interactions and the temperature-dependent C0, which also playan important role on the martensitic transformation in these alloys. Furthermore, wedemonstrate that a proper account of the temperature and composition dependence ofC0 gives us reasonable theoretical TM(x) values in Ni2+xMn1-xGa alloys. Also in this type of Ni-rich and Mn-deficient alloys, by using the Heisenberg model in combination with the mean-field approximation, the abnormal trend of experimental magnetic transition temperature TC(x) with respect to the composition x is shown to be well captured by the theory.QC 20110830

Pre-literate children experience written text as a meaningless material object, the word-object, but the compulsory and institutional aspects of reading pedagogy make this an experience from which they cannot escape. Some children begin to associate their own negative experiental sense with the word-object before they are able to learn to read. As reading pedagogy continues, these children begin to read back experiental sense which prevents them from converting the word-object to meaningful text. Experiental sense is repressed because it is psychically painful. It retains qualities of phenomena repressed from childhood: it is active and intractable to reason. The result is an intractable illiteracy which may be interpreted as biologically based �dyslexia.� Further attempts at reading pedagogy in childhood and adulthood generally result in reproduction of the inability because this pedagogy requires learners to attempt to read linguistically which elicits experiental sense. As these children become adults, their avoidance of reading sometimes structures their social relations to accommodate and compound their problems. The method to overcome the problem replaces experiental sense with positive feelings about written language. The power of language to denote emotions of pleasure and affirmation from learners� lives is used. These emotions are enhanced through a technique of affirmative intersubjectivity. Short spoken affirmative texts are made by learners, tape recorded and reproduced as written texts by the literacy worker. Through allowing learners control and autonomy over their spoken and written texts, the positive emotions in them are associated by learners with the written texts. Exercises on the affirmative written texts are used to demonstrate regularities about written language. Learners then progress to reading suitable independent texts and other activities. There are suggestions about how to enhance learners� feelings as competent readers and writers. The thesis uses a methodology of action research and includes five case studies of adults with literacy problems. Concepts from social theory, psychoanalysis and object relations theory are used and adapted to understand written language, schooling and illiteracy.

Many nation-states have their potential for growth hindered by the involvement of developed nations. These low-income nation-states are primarily located on the continent of Africa. There are three parts to this phenomenon of neocolonialism which is the process of continuing involvement of developed nations in developing nations that creates a negative growth in those nations. The research I've conducted is in three parts. The first consists of analyzing the social construction of neocolonialism, how the phenomenon occurs, and where it stems from. The second part is to show how this involvement is damaging to the developing nations. I will use examples such as the multinational corporation profit recycling, the life of foreign aid, and unwise economic deals. As it turns out the phenomena brings on the hindrance of developing in the low-income nation. The last part of my research is to come up with an economic improvement plan. For instance, rather than country A trading money (or some monetary value) for a resource in country B, "A" would build a school, hospital, or infrastructure in "B" to improve the conditions in the low-income nation. It is hypothesized that will leave room for growth in both nations without creating harmful economic repercussions because money would be taken out of the equation.B.A.

The concept of a tree has been used in various areas of mathematics for over a century. In particular, trees appear to be one of the most fundamental notions in computer science. Sequential algorithms for trees are generally well studied. Unfortunately many of these sequential algorithms use methods which seem to be inherently sequential. One of the contributions of this thesis is the introduction of several parallel techniques for the construction of various types of trees and the presentation of new parallel tree construction algorithms using these methods. Along with the parallel tree construction techniques presented here, we develop techniques which have broader applications.
We use the Parallel Random Access Machine as our model of computation. We consider two basic methods of constructing trees:tree expansion and tree synthesis.
In the tree expansion method, we start with a single vertex and construct a tree by adding nodes of degree one and/or by subdividing edges. We use the parallel tree expansion technique to construct the tree representation for graphs in the family of graphs known as cographs.
In the tree synthesis method, we start with a forest of single node subtrees and construct a tree by adding edges or (for rooted trees) by creating parent nodes for some roots of the trees in the forest. We present a family of parallel and sequential algorithms to construct various approximations to the Huffman tree. All these algorithms apply the tree synthesis method by constructing a tree in a level-by-level fashion. To support one of the algorithms in the family we develop a technique which we call the cascading sampling technique.
One might suspect that the parallel tree synthesis method can be applied only to trees of polylogarithmic height, but this is not the case.We present a technique which we call the valley filling technique and develop its accelerated version called the accelerated valley filling technique. We present an application of this technique to an optimal parallel algorithm for construction of minimax trees.Science, Faculty of
