Academic literature on the topic 'Theoretical References'

Abstract The article describes conceptual aspects related to the artistic tendencies in preschool education.The realization of this process is presented by operating with the concepts of the famous occidental, Russian and local scientists. One of the ideas characteristic to the scientists’ pedagogical thinking is that in the process of formation/development of the child through arts, the child is submitting the objects and phenomena to his/her previously acquired assimilation schemes. To insure integrity in the practical way of the early education, the methodology we are proposingis based on a research, a significant theoretical network ofsuccessful pedagogical practicesof word known scientists. The analyzed theories are a source of inspiration and constitute the theoretical universe which contributes to as-truthful-as-possible preschool educationof the child.Early education is the most important period in one’s life through the sustainable consequences it has on his/her ultimate development.

Theoretical and model analysis of the unreliability of cardiac output measurement by means of the thermodilution methodThermodilution is the clinically most often applied method of cardiac output measurements. This method is based on thermal indicator (iced isotonic salt solution) variation measurements by a Swan-Ganz catheter located inside the pulmonary artery. The unreliability of thermodilution should be estimated theoretically because of the lack of references. In this paper an attempt has been made to estimate theoretically the unreliability of thermodilution cardiac output measurements.

The article discusses the motivation to learn as a part of the subject-subject pedagogical interaction. It is presented as an active multifaceted pedagogical, psycho-age and social problem. And also as a problem related to the overall development of school education. The problem of motivation in the school environment is considered theoretically. On this basis, references are made to the various practical situational models proposed in the scientific literature. Motivation is shaped as a specific problem area that is directly related to the school environment; the intellectual and cognitive development of the student; methodical and didactic skills of the teacher.

The literature on referencing takes a firm stance on the value that vendors derive from marketing customer references. What the literature lacks, however, is empirical work that supports our current understanding of the value of customer references to the potential customer. The present exploratory research aims to demonstrate the value of customer references from the perspective of the potential customer. This goal will be achieved by considering a single case study that provides evidence for the value of customer references to potential customers in business markets. Three theoretical propositions emerge as key conceptual contributions: (a) customer references allow buying companies to establish their suppliers’ competence, assess the buying decision risk and forecast return on investment; (b) customer references deliver value by helping potential customers to identify new business needs and (c) potential customers benefit from being exposed to customer references insofar as they are sources of organizational learning. This work concludes by presenting recommendations for practitioners who wish to reap the full benefits of customer references.

This article discusses the typical form and content of forty theoretical scientific papers. These papers were chosen from the 400 most-cited papers in the Science Citation Index for the period 1945–1988 (reported by Eugene Garfield in a series of recent essays appearing in Current Contents). It was found that the typical form for these papers is similar to that for experimental and methods papers, but the content differs substantially. In brief, the content follows the logical sequence: problem or need, assumptions made in attempting to solve problem or meet need, theorem derived from those assumptions and additional considerations, proof of theorem by logical reasoning or validation by comparison with what is established or establishable, conclusions from previous discussion, and recommendations on future experimental or theoretical work. Also, compared with experimental and methods papers, these theoretical papers have somewhat fewer figures and tables, but many more references and equations.

Asset-Income declaration and auditing has been becoming hot issues in the revolution of anti-corruption in our country in recent years. This study mainly use qualitative analysis methods, synthesis, inductive and explanatory methods, combined with law references. Our research results show that asset-income declaration audit follows a process with several steps: planning, conducting audits, audit reports and examining audit conclusions. We recognize that a transparent declaration audit will benefit the public in anti-corruption revolution.

Container houses have exhibited huge advantages in such aspects as building efficiency, environmental protection and sustainability. The theoretical basis of the recycling design of waste container is formed based on the idea of reuse design and the idea modular design and the idea of energy-saving design and the idea of improving design combination. This article also obtained the inventive principle of the reuse design of waste containers from the theory of TRIZ. This article will provides certain references for the future transformation design of the containers.

The field study based on a questionnaire, classroom observation and a range of interviews with government officials and teachers confirmed a deeply negative attitude towards the way SiSwati is being taught, resulting in negative attitudes towards the language itself. Other findings pointed to a resistance to the cultural content of the curriculum as dictated by the power elite in Swaziland, the outdated emphasis on linguistics rather than sociolinguistics as an informing discipline and the absence of social and negative literacy skills embedded in subject content. The field study reflects an overall climate of despondency governing the teaching and learning context.

The aim of this thesis is to study certain linear connections arising in physics; and in particular metric connections, Weyl connections and Cartan connections are examined. Emphasis is placed on the holonomy group of the connection and the relationships between the relevant geometric objects in the physical theories. The appropriate mathematical background is reviewed in the first two chapters and various notions from differential geometry are introduced. Proofs of theorems relating covariantly constant and recurrent tensors with holonomy are given in detail, and Eisenhart's results on connections induced in submanifolds are given a modern treatment. The relationship between a metric, its Levi-Civita connection and its curvature tensor is examined in chapter three. Some new results on the problem of how to 'recognise' a metric curvature are presented and the idea of a 'curvature copy' - different linear connections with the same curvature - is discussed. Weyl's elegant attempt to unify gravity with electromagnetism is the topic of the fourth chapter. A full holonomy classification of Weyl connections is given in this chapter, along with results concerning the relationship between metric, connection and curvature. The Cartan connection was introduced by Cartan as a device for placing Newtonian gravity in a similar formal setting to Einstein's theory of gravity. This connection is studied in chapter five and reference is made to holonomy properties, symmetries and reduction of the bundle - which enables Newtonian gravity to take on the appearance of a gauge field theory.

The coupled-cluster (CC) equations including single, double, triple and quadruple excitations (CCSDTQ) are qraphically derived using Feynman diagrams. These equations are programmed and an iterative reduced linear equation method is used to solve these equations. A few points on the potential curves for the dissociation of some model systems with a single bond (LiH and Li₂) are calculated using CC doubles (CCD), singles and doubles (CCSD), singles, doubles and triples (CCSDT) and CCSDTQ. These calculations demonstrate the magnitude of the CC contributions arising from triple and quadruple excitation amplitudes to the stretching of a chemical bond. A multi-reference coupled-cluster singles and doubles (MRCCSD) method utilizing two reference determinants, which differ by a two electron excitation, is then proposed. One of these determinants is selected as the formal reference determinant. The proposed method is based on the single-reference coupled-cluster equations truncated after quadruples with appropriate restrictions placed on the triple and quadruple amplitudes to allow only those amplitudes which correspond to single and double excitations from the second reference determinant. The computational expense of this method is no more than twice that of singles and doubles from a single reference (CCSD). These equations are programmed and the potential curves for the dissociation of a few model systems with single bonds (LiH, BH, and H₂O) are calculated to demonstrate the correct bond dissociation properties of this method. These calculations also demonstrate how much of the CC energy contribution arising from the triple and quadruple excitation amplitudes can be attributed to single and double excitations from the second reference determinant.

The chemistry of actinides in aqueous solution is important, and it is essential to build adequate conceptual models and develop methods applicable for actinide systems. The complex electronic structure makes benchmarking necessary. In the thesis a prototype reaction of the water exchange reaction for uranyl(VI), for both ground and luminescent states, described with a six-water model, was used to study the applicability of density functional methods on actinides and different solvation models. An excellent agreement between the wave function methods CCSD(T) and MP2 was obtained in the ground state, implying that near-minimal CASPT2 can be used with confidence for the reaction in the luminescent state of uranyl(VI), while density functionals are not suited to describe energetics for this type of reaction. There was an ambiguity concerning the position of the waters in the second hydration sphere. This issue was resolved by investigating a larger model, and prop- erly used the six-water model was found to adequately describe the water exchange reaction. The effect of solvation was investigated by comparing the results from conductor-like polarizable continuum models using two cavity models. Scattered numbers made it difficult to determine which solvation model to use. The final conclusion was that the water exchange reaction in the luminescent state of uranyl(VI) should be addressed with near-minimal CASPT2 and a solvation model without explicit cavities for hydrogens. Finally it was shown that no new chemistry appears in the luminescent state for this reaction. The thesis includes a methodological investigation of a multi-reference density functional method based on a range separation of the two-electron interaction. The method depends on a universal parameter, which has been determined for lighter elements. It is shown here that the same parameter could be used for actinides, a prerequisite for further development of the method. The results are in that sense promising.

In this dissertation it is argued that the concept of literary intelligence as used and developed by Frank Raymond Leavis and other members of his Scrutiny circle is a viable theoretical and educational notion and is long due a reappraisal. Their thesis that reading quality texts intelligently assists our personal and moral development is taken up and subjected to philosophical analysis. It is also argued that a theory of intellectual virtue is best suited for such a reappraisal. Literary intelligence is then found to be best interpreted as a form of Aristotelian practical intelligence. This interpretation allows us to theorize the moral salience of literary experiences. This theorization is achieved through an in-depth analysis of relevant articles written by Leavis, Harding and Bantock, assorted writings on the relationship between life and art as envisaged by a number of thinkers, as well as a sustained analysis of the theory of intellectual virtue. In particular, recourse is taken to the theory of intellectual virtue as drafted by American philosopher Linda Trinkaus Zagzebski. Consequently, a number of educational implications of the above theories are identified and commented upon. Also, it is shown that the above-mentioned theoretical insights fit in well with the consistent findings of research into reading. Finally it is argued that if the capacity to read well is best approached as a moral trait, then reading education cannot be legitimately conceptualized as one ‗competence‘ among others. On the contrary: reading education ought to form the moral kernel of the curriculum. A sustained and socially sanctioned emphasis on the fostering of reading and the creation of a culture of literacy will widely expand the social, cultural and moral horizons of children and adults alike

Thesis (DLitt (Afrikaans and Dutch))--University of Stellenbosch, 2010.<br>ENGLISH ABSTRACT: This dissertation is an attempt to design a theoretical model for an encyclopaedic dictionary for Gabonese languages. It makes specific reference to Yilumbu, a developing language of the Bantu phylum (B44, according to Guthrie’s classification) spoken in Gabon and in Congo. All existing metalexicographic studies on Gabonese languages (including Yilumbu) pursue the compilation of comprehensive language dictionaries. Most of them are bilingual languages. On the other hand, a number of encyclopaedic dictionaries exist for Gabonese languages. Most of them were compiled by Catholic and Protestant missionaries and colonial administrators. However, none of these reference works was compiled on the basis of a prior metalexicographic orientation. Ultimately, the present study is the first of its kind to propose an encyclopaedic dictionary for Gabonese languages on the basis of a comprehensive metalexicographic analysis. This dissertation also shows that the planned encyclopaedic dictionary reflects the language planning needs of Gabon. Developing and documenting the Gabonese languages on all levels of communication in order to address all the roles and user characteristics are a great challenge. As far as encyclopaedic dictionary compilation is concerned, acquaintance with state-of-the-art developments in the theory and practice of lexicography is necessary. This dissertation comprises nine chapters. Chapter 1 mainly focuses on the specific aims, the purpose and the motivation of the study. The research problem is also demarcated in this chapter. Furthermore, the chapter presents the theoretical model that provides the framework for this research as well as the methodological approach adopted. The potential impact of the study, the reasons for and the position of the source and target languages as well as the sociolinguistic situation of Yilumbu are also introduced in the first chapter. Chapter 2 is a review of the dictionary typology with reference to the proposed model. It aims to present a typological framework for the planned encyclopaedic dictionary. It also introduces various dictionary typologies and contrasts encyclopaedic lexicography and general lexicography. The chapter concludes with a typological profile of the planned encyclopaedic dictionary for Yilumbu before outlining specific principles of the proposed model for an encyclopaedic dictionary. Chapter 3 is a review of encyclopaedic lexicography in Gabon. It introduces the concept of encyclopaedic lexicography. Then it provides a literature review of lexicographic surveys in the Gabonese languages by presenting existing encyclopaedic works in Gabon. The chapter also outlines recent trends in Gabonese lexicography in order to explain the situation of encyclopaedic lexicography in Gabonese lexicographic studies. Finally, the need for research in encyclopaedic lexicography in the Gabonese languages is underlined and specific advantages of encyclopaedic research for Yilumbu lexicography are introduced. Chapter 4 focuses on the target users of the planned encyclopaedic dictionary and its lexicographic functions. The chapter starts with a broad outline of target users and the activity of dictionary compilation. It also reviews what is known as target users and outlines user characteristics. The lexicographic functions of the planned encyclopaedic dictionary are also outlined in this chapter. Chapter 5 gives a comprehensive presentation of the frame structure of the planned encyclopaedic dictionary of Yilumbu. More specifically, the chapter provides a definition of the concept of frame structure and schematises the frame structure, highlighting its components. It outlines the accessory texts and the outer texts of the planned dictionary. This chapter also contains an outline of the front matter and the back matter strategies used for the Yilumbu encyclopaedic dictionary project. The central word list is also dealt with in this chapter. Finally, the chapter reports on the proposed frame structure functions. Chapter 6 focuses on the macrostructure of the planned dictionary. In this chapter, a general overview of the concept of macrostructure is first given. Then the chapter presents the dictionary basis and the selection of the lemma candidate list. Further macrostructural issues are also described. In Chapter 7, different aspects of the microstructure are discussed, focusing on a number of contributions. The chapter presents the concept of microstructure according to Hausmann and Wiegand (1989) and enumerates the different types of article to be included in the microstructure. Data to be included in the microstructure are also presented. Chapter 8 discusses the notion of access structure and its related concepts, namely outer access structure, inner access structure and search zones. The effectiveness and success of any dictionary is measured, among other things, by the accessibility and retrievability of the desired information. The chapter contains an overview of the concept of access structure and also deals with the outer access structure. Moreover, the chapter presents the inner access structure and the rapid access structure. The mediostructure is finally dealt with as a way of gaining access to data. Chapter 9 provides a comprehensive conclusion of the dissertation. This chapter also outlines the contribution of the research findings to lexicographic research, to the emerging Gabonese lexicography and to the fuller promotion of the Yilumbu language. It provides conclusions and formulates suggestions for further research.<br>AFRIKAANSE OPSOMMING: Hierdie proefskrif is 'n poging om 'n teoretiese model te ontwerp vir 'n ensiklopediese woordeboek vir Gaboenese tale.

The recent emergence of ‘Iberian Studies’ requires a crucial reflection on the challenges and potentialities associated with this area. This volume intends to contribute to methodological renewal and compiles essays that explore possibilities of analysis over the Iberian space and related phenomena. It offers a plural framework of theoretical references and perspectives, in which the challenges posed by Basque, Catalan and Galician cases are especially focused. Thereby, this book is a valuable tool for reading the current situation and for developing a new critical thinking about this object of study.

The weld is a typical dissimilar metal weld (DMW). As its large grain, anisotropism and narrow moving space for probe, it is difficult for practical ultrasonic testing. On the basis of studying weld structure, this thesis firstly discusses the sonic propagation path of different incident angle, and then calculates the reflectivity and transmittivity, from which the ratio-angle curve will be plotted, finally simulates &amp; analyzes the ultrasonic testing with software CIVA. The analysis results show that proper selection of the incident angle will provide suitable incident angle range for the following experiments. With the CIVA analysis results, it will also provide references for choosing proper probe parameters and relative technics for following research.

The quasi-orthogonal surface method of calculation of three-dimensional flow of references (1, 2, 3) is extended to take account of the influences of upstream and downstream flow and to include various losses in the impeller. By this method, the three-dimensional flow distribution of two impellers were calculated and the results were compared with experimental data. It was found that the calculation results of the present method which takes account of the gradient of entropy and the upstream and downstream conditions are in closer agreement with the experimental results than the previous method.

The quality of hydro-expanded double-layered tubes depends on the hydro-expanding pressure. Therefore, it is very important to determine the range of the hydro-expanding pressure accurately during the fabrication of double-layer tubes. According to theories of elasticity and plasticity, the responses of double-layered tubes subjected to five kinds of cases were analyzed during the hydro-expanding process. And the stress and strain for inner and outer tubes of double-layered tubes were discussed. By using the relation of deformed compatibility of hoop strain, suitable condition of hydraulic expansion and variable range of hydro-expanding pressure were obtained, and the calculating formulas between the hydro-expanding pressure and residual contact pressure was derived. Use the non-linear FEA MSC.patran/marc code to simulate the deformation and stress distribution, the whole process of hydraulic expansion was numerically investigated, in which the nonlinearities of the material, geometry and contact were all taken into account. The results show that the range of the hydro-expanding pressure from the numerical simulation is in good agreement with those from theoretical calculation with a maximum relative error of 6.52%. The investigation on the hydraulic expansion of double-layered tubes may guide the engineering design and provide references for further research.

Software is ubiquitous in an information-based society. Market complexity requires companies to employ open innovation, incorporating external knowledge and providing knowledge to its’ partners. It is aimed to investigate the characteristics of international scientific literature on open innovation and software development, their theoretical affinities and the most relevant authors. As methodological procedures, bibliographic coupling is used, with Social Network Analysis principles, verifying: references in common between papers on this theme, production by country and its annual average. As a result, it is evident that developed countries have higher production on the topic, despite the low annual average. The most referenced papers discuss profitability strategies using open source code. It is concluded that open innovation enables software companies to share knowledge and contribute to the development of society

The present paper offers that most of the advocates of discipline of library and information science believe that there is a lack of theoretical foundation and rational identity. The author maintains that there has been an error in defining the subject by confusing library with librarianship. That is many researchers have derived the concept of librarianship from library. Therefore they came to define librarianship as an entity only through the social application and services. If instead, a librarian was assumed to be a person who was usually a scholar, with or without the knowledge of classification properly, and if it was further assumed that before establishing any library, at least there has always been one thoughtful person with the enthusiasm of classifying his own tacit or explicit knowledge in order to retrieve, the concept of librarianship could have been derived from the concept of personal seeking of knowledge, or the need of any knowledgeable person who believes in scientific classification for the sake of retrieval. Thus, there has always been the necessity for scientific classification even if there has not been any formal library. So, I propose that librarianship is more related to the knowledge retrieval and classification which is in the mind of all people specially scholars and learned men before the library, as a place for the collection of books and other materials come to being.

The paper historically describes the application and development of the centrifugal compressor from the very beginning of its introduction until today. It focuses on selected practical and theoretical examples that — to the author’s opinion — pushed the centrifugal’s standard from simple, low efficiency designs to its current high level status. The main events related with this development like the impact of the industrial revolution and the introduction of jet propulsion are pointed out. The implication of improved theoretical tools becoming available with raising computer capacity and the impetus of advanced measurement techniques on the centrifugal’s improvement are described. A considerable number of references offers the possibility to engross the thoughts.

From 1962 Lancashire, in England, became the focus of a major renewal scheme: the creation of a ‘super-city’ for 500,000 people. The last and largest New Town designated under the 1965 Act, Central Lancashire New Town (CLNT) differed from other New Towns. Although influenced by the ideals and example of Garden City model, its master plan followed new and proposed infrastructure to connect the sub-region’s poly-centricity. By unifying and expanding existing towns and settlements it aimed to generate prosperity on a sub-regional scale using the New Towns Act, rather than creating a single new self-sufficient urban development. CLNT’s scale, poly-centricity and theoretical growth made it unique compared to other new town typologies and, although not realised, its planning can be traced across Lancashire’s urban and rural landscape by communication networks and city-scale public and civic buildings. With reference to diagrams for the British New Towns of Hook, Milton Keynes and Civilia, this paper will contextualize and evaluate CLNT’s theoretical layout and its proposed expansion based on interdependent townships, districts and ‘localities’. The paper will conclude by comparing CLNT’s theoretical diagram with its proposed application and adaptation to the sub-region’s topographical physical setting.

This paper proposes an alternative design procedure for current control of LCL-filtered grid-tied inverters, taking into account robustness against uncertain and possibly timevarying grid inductances. The control strategy is developed in stationary reference frame, and is based on a partial state feedback, including an active damping scheme of the LCL filter resonance. From the system parameters and the design specifications, analytical expressions for the calculation of the control gains are provided, oriented by a pole placement in discretetime domain. These expressions are obtained neglecting the dynamics of the filter capacitor, including resonant controllers to track sinusoidal references, and taken into account the delay due to digital implementation. To certicate robust stability of the closed-loop system undertime-varying grid inductances, a theoretical analysis based on a Lyapunov function is provided. Time and frequency domain results are presented for a case study, illustrating that the proposed design strategy is able to provide robust control gains leading to grid-injected currents with suitable responses for the entire range of grid inductances considered in the design.

"Reported is the synthesis of a series of seven studies on work and health, conducted collaboratively by researchers in applied psychology and occupational medicine. This qualitative meta-study develops a framework, in which reviewed studies are structured, aggregated, integrated, and interpreted in a theory-guided iterative process of themed analysis. Building on empirical results, the subsequent interpretive integration seeks to demonstrate, how overarching, pervasive, and in psychological research typically underemphasized tendencies of “subjectification” manifest in exemplary work contexts, research topics, and results. Subjectification of work is operationalized in dimensions of work intensification (performance focus), work internalization (goal adoption), and work individualization (job personalization). A meta-dimension is work insecurity (personal risk), cultivated in contemporary management ideologies of employee self-reliance. Following thematic description, content-analytical structuring criteria include: a) focus on work task (activity) versus working conditions (context); b) primary (close, direct, explicit) versus secondary (inferred, indirect, subtle) references to and/or indication for identified tendencies of subjectification; and c) theoretically assumed and empirically examined relationships with negative (psychopathological) and positive (psychosalutogenic) short, medium, and longer-term attitudinal and health-related work effects, as well as the personality-shaping impact of long-term occupational socialization. Psychological aspects of work tasks are core to 4 studies, 3 focus on working conditions and organizational practices. References to intensification were dominant in 4 studies, whereas 5 include internalization processes, and 3 predominantly focus on individualization of work. All studies share secondary or indirect references to other subjectifying tendencies. Examined work effects were aggregated into a matrix of short, medium and long-term positive and negative manifestations of health and wellbeing. Results suggest tensions and pressures arising from the motivational individualization of work tasks and conditions, resulting internalization of organizational interests and goals (e.g., performance, efficiency, costs), coupled with system-inherent tendencies of work intensification. These dysfunctional dynamics constitute risks factors for psychologically detrimental or harmful forms of self-management, self-control, and self-endangering work behavior, as manifestations of “internalized” incompatibilities between work and health in the neoliberal workplace, aggravated by existential threats associated with political-economic crisis. Outlined are implications of subjectification for a critical reevaluation and reorientation of basic theoretical assumptions of research and practice in applied psychology and occupational health."

Walter Bagehot (1873) published his famous book, Lombard Street, almost 150 years ago. The adage “lending freely against good collateral at a penalty rate” is associated with his name and his book has always been set on a pedestal and is still considered as the leading reference on the role of lender of last resort. Nonetheless, without a clear understanding of the theoretical grounds and the institutional features of the British banking system, any interpretation of Bagehot’s writings remains vague if not misleading—which is worrisome if they are supposed to provide a guideline for policy makers. The purpose of the present paper is to determine whether Bagehot’s recommendation remains relevant for modern central bankers or whether it was indigenous to the monetary and banking architecture of Victorian times.
