OLIVIERI, ARIANNA. "Crystallographic Coxeter groups and Kac' denominator formula." Doctoral thesis, Università degli Studi di Milano-Bicocca, 2018. http://hdl.handle.net/10281/241351.
Full textAbstract:
Questa tesi esplora la connessione tra un sistema cristallografico di Coxeter (W, S) e le radici di un'algebra di Kac-Moody Lie arbitraria associata a una Matrice di Cartan Generalizzata simmetrizzabile con il gruppo Weyl W attraverso la formula del denominatore Kac.
La formula è parametrizzata quando conosciamo esplicitamente la molteplicità delle radici dell'algebra di Kac-Moody Lie. Il lato sinistro della formula del denominatore Kac dipende interamente dal gruppo Coxeter. Uno degli obiettivi più importanti è quello di calcolare questo lato sinistro per i gruppi cristallografici di Coxeter con infty-decomposition. Ciò è possibile perché il lato sinistro può essere reinterpretato con la serie completa di crescita applicata alla traccia e utilizzando diversi fatti sulla serie di crescita completa dei gruppi di Coxeter cristallografico con infinita-decomposizione.
Nel Capitolo 1 mostriamo alcune proprietà del cociclo che si trovano nella parte sinistra della formula del denominatore Kac.
La formula del denominatore Kac è stata già stabilita per alcune classi di gruppi di Coxeter. La classe dei gruppi di Coxeter è divisa in tre tipi principali: finiti, affini e indefiniti. La formula del denominatore Kac è stata appena parametrizzata per gruppi di Coxeter finiti e affini e anche per alcuni gruppi di Coxeter indefiniti. Quindi dobbiamo lavorare con la classe di gruppi di Coxeter indefiniti. Esiste una classe di gruppi di Coxeter indefiniti, uno dei cosiddetti gruppi di Coxeter iperbolico. Questi gruppi hanno attirato molta attenzione tra i matematici negli ultimi anni.
Nel Capitolo 3 abbiamo dedicato molto impegno a rappresentare l'unica classe di isomorfismo dei gruppi di coxeter iperbolici cristallografici cocompact come un reticolo aritmetico cocompatto del gruppo ortogonale di matrici con voci reali che stabilizza una forma bilineare di firma (3,1) e con entrata positiva in posizione (1,1). Poi abbiamo anche ottenuto una rappresentazione del gruppo di Coxeter anche nello speciale gruppo lineare delle matrici 2x2 con coefficienti complessi prodotto semidiretto con una particolare involuzione esterna, utilizzando e calcolando un particolare isomorfismo di gruppo, che si dice sia eccezionale. Inoltre abbiamo ottenuto una descrizione del sistema di radici di una algebra di Kac-Moody Lie con questo gruppo cristallografico di Coxeter come gruppo di Weyl. In generale è estremamente difficile determinare o caratterizzare tutte le radici immaginarie ma grazie a una costruzione di una mappa lineare e ad un risultato importante di R. V. Moody sulle radici delle algebre di Kac-Moody Lie iperboliche è possibile in questo caso
Nel capitolo 4 studiamo i sistemi cristallografici di Coxeter (W, S) con una sferica infinita-decomposizione. Il nostro scopo è quello di trovare una formula esplicita per il lato sinistro della formula del denominatore Kac per i gruppi cristallografici di Coxeter con una sferica infinita-decomposizione. Usiamo il fatto che questi gruppi sono prodotti liberi di gruppi con amalgama, quindi gli elementi hanno un'espressione unica in una forma normale canonica.
Ciò consente di interpretare il lato sinistro della formula del denominatore Kac come una serie di potenze formali (chiamate serie Cocycle) di alcuni elementi dell'anello della serie di potenze formali con coefficienti nell'anello del gruppo Z [W], dove Z è il anelli interi e W è il gruppo considerato.<br>This thesis explores the connection between a crystallographic Coxeter system (W,S) and the roots of an arbitrary Kac-Moody Lie algebra associated with a symmetrizable Generalized Cartan Matrix (GCM) with Weyl group W through the Kac' denominator formula.
The formula is parametrized when we explicitly know the multiplicity of the roots of the Kac-Moody Lie algebra. The left hand-side of the Kac' denominator formula depends entirely on the Coxeter group. One of the most important goals is to calculate this left hand-side for crystallographic Coxeter groups with infty-decomposition. This is possible because the left hand-side can be reinterpreted with the complete growth series applied to the trace and using several facts on the complete growth series of crystallographic Coxeter groups with infty-decomposition.
In Chapter 1 we show some properties of the cocycle that is in the left hand-side of the Kac' denominator formula.
Kac' denominator formula has been already established for some classes of Coxeter groups. The class of Coxeter groups is split into three principal types: finite Coxeter groups, affine Coxeter groups and indefinite Coxeter groups. Kac' denominator formula has just been parametrized for finite and affine Coxeter groups and also for some indefinite Coxeter groups. Then we must work with the class of indefinite Coxeter groups. There is one class of indefinite Coxeter groups, the one of the so-called hyperbolic Coxeter groups. These groups have attracted much attention among the mathematicians in recent years.
In Chapter 3 we spent much effort to represent the only one isomorphism class of cocompact crystallographic hyperbolic Coxeter groups as a cocompact arithmetic lattice of the orthogonal group of matrices with real entries that stabilizes a bilinear form of signature (3,1) and with positive entry in position (1,1). Then we also obtained a representation of the Coxeter group also in the special linear group of the matrices 2x2 with complex coefficients semidirect product with a particular external involution, using and computing a particular group isomorphism, said to be exceptional. Moreover we obteined a description of the root system of a Kac-Moody Lie algebra with this crystallographic Coxeter group as Weyl group. In general it is extremely difficult to determine or characterize all imaginary roots but thank to a construction of a linear map and to an important result of R. V. Moody about the roots of the hyperbolic Kac-Moody Lie algebras it is possible in this case.
In Chapter 4 we study crystallographic Coxeter systems (W,S) with a spherically infty-decomposition. Our aim is to find an explicit formula for the left hand-side of the Kac' denominator formula for the crystallographic Coxeter groups with spherically infty-decomposition. We use the fact that this groups are free product of groups with amalgamation, therefore the elements have a unique expression in a canonical normal form.
This allows to interpret the left-hand side of the Kac' denominator formula as a formal power series (called Cocycle series) of some elements of the ring of formal power series with coefficients in the group ring Z[W], where Z is the integer rings and W is the considered group.

A collection of poems exploring the relationship between self, interpretation of memory, and the dynamic structure of families, nuclear and not. The notion of family as a wider concept, a unit that can be heartily constructed, maintained, and destructed beyond the ties of blood relations, is a focus of numerous poems in the collection. The title poem, “Numerator Denominator,"? evokes, through associative leaps in language, the implicit shifts of emotion that surround personal relationships—the countless divisions and facets of oneself exposed. The structures of the poems in the collection range from free verse to a nonce sonnet sequence to the repetitive drive of the sestina. The poems are not divided into sections, but are arranged in such a way that connects the themes and flow of the work while still allowing the reader to explore her/his own connections throughout the collection.<br>Master of Fine Arts

Full textAbstract:
Let R be a commutative ring. To each finitely presented R-module M one can associate an ideal, Fit_R(M), called the (zeroth) Fitting ideal of M . This ideal is always contained within the R-annihilator of M . Now let R be an integrally closed complete Noetherian local ring and let Λ be a (not necessarily commutative) R-order. A. Nickel generalised the notion of the Fitting ideal, providing a definition of the Fitting invariant for finitely presented modules M over Λ. In this case, to obtain the relation between the Fitting invariant of M and the annihilator of M in the centre of Λ, one must multiply the Fitting invariant of M by a certain ideal, H(Λ), of the centre of Λ, called the denominator ideal of Λ. H. Johnston and A. Nickel have formulated several bounds for the denominator ideal and have computed the denominator ideal for certain group rings. In this thesis, we prove a local-global principle for denominator ideals. We build upon the work of H. Johnston and A. Nickel to give improved bounds for the denominator ideal of Λ assuming some structural knowledge of Λ. We also build upon the work of P. Schmid and K. Roggenkamp to determine structural information about certain group rings. Finally, we use this structural information to compute the denominator ideal of group rings R[G], where G is a p-group with commutator subgroup of order p.

The aim of this research is to investigate characteristics of accident denominators across age groups in mining and associated process industries in the Port Hedland region of Western Australia. Emphasis has been focussed on comparing young, inexperienced groups with older, more experienced groups. A literature review revealed some key contributors to accidents among younger workers, in particular, those who had only recently entered the workforce. The review also revealed contributors impacting accidents regarding other age groups over a wide range of industry types. From these findings an accident construct model and questionnaire were designed to identify contributing and mitigating denominators which input to accidents occurring across the defined age groups.

Full textAbstract:
Context: In the last decade, Agile software development methods were proposed as a response to plan-driven methods. The main aim for this paradigm shift was to cope up with constant changes. Core values that are central to agile methods are described in Agile Manifesto. Agile practices define how agile methods are implemented in practice. Objectives: This study aims to investigate what practices were considered and adopted as part of agile philosophy, and identify evidence on the use of agile practices in reference to what defines agile. Methods: We conducted a systematic literature review. The review includes 186 primary studies published between 2000 and 2010. Quality assessment based on rigor and relevance as identified in the selected papers has been conducted. Non-empirical papers were classified based on themes they addressed. Empirical papers were analyzed based on two factors: 1. if they described the use of agile practices for a software project/product in general, 2. if they described the use of agile practices for a specific purpose/activity Application type, team size and experience of subjects in the primary studies were extracted. The alignment between practices reported in the studies with the core agile values is analyzed. Results: A total of 119 studies were conducted in industry and 67 in academia. Nearly half the papers published by researchers are non-empirical and present analysis of agile practices in various topics. Over half of the empirical papers were focused on evaluation/assessment of a specific aspect of agile. ‘Pair programming’ received most attention in this direction. Among the empirical studies that described agile practices for academic projects, ‘Pair programming’ and ‘Test driven development’ were the most considered practices. Among the 119 studies conducted in industry, 93 studies described the use of agile practices for the overall project/product development while the remaining studies described experiences of single practices like Pair Programming or the modification/adoption of agile for non-software aspects in software projects. Practices adopted have been ranked based on team size, practitioners’ experience and application type. A method for agile assessment based on core agile values is developed and exemplified. Conclusions: Practices that are considered agile vary with context although ‘Pair programming’, ‘Continuous integration’, ‘Refactoring and Testing continuous throughout the project are the most common practices used. ‘Test driven development’ was not highly adopted by practitioners. But it was not clear if test cases were written before code construction in projects where continuous testing was performed. However, this was completely opposite in academic projects. Practices ‘On-site frequently modified. In many of the studies inspected, practices adopted were not aligned with agile values. Although practices related to technical aspects of software development are in place, agile practices that focus aspects like ‘working together’ and ‘motivated individuals’ are often not used in practice. Moreover, many of the studies were not reported to an extent that it was possible to draw any inferences on the usability/applicability, benefits and limitations of the agile practices. To this end, a major implication is to improve the quality of the studies and a need for a common framework to report the results of agile practices’ adoption.

We investigate the influence on the solutions of finite-difference schemes of using unconventional denominator functions in the discrete modeling of the derivatives for ordinary differential equations. The derived results are a consequence of using a generalized definition of the first derivative of a function. Two explicit examples, the linear decay equation and the Logistic differential equation, are used to illustrate in detail the various solution possibilities that can occur.

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Urban Studies and Planning, 2001.<br>Includes bibliographical references (p. 331-361).<br>This study explores the collective negotiation behavior of the developing countries of the South in international environmental politics. The so-called 'South'-represented in global negotiations by Group of 77 (G77)-is an unwieldy and unlikely collective made up of over 130 countries displaying dramatically different economic conditions, ideological persuasions, political systems and geographic features and environmental endowments. Yet, for over 30 years now, the collective has demonstrated remarkable resilience in the face of internal divisions as well as external threats. Although sometimes described as an economic collective 'of the poor', the South is, in fact, a political collective 'of the marginalized'. Its resilience stems from its member's strongly shared sense of exclusion from the international system and their collective desire to change the 'rules of the game'. This resilience, however, has often come at the cost of having to slip into 'lowest common denominator' positions. In following an 'asymmetrically prescriptive-descriptive' research approach, this study seeks to explore the nature of the 'South' as a negotiating collective and understand why it tends to slip into lowest common denominator positions. The study uses the case of global negotiations on the Desertification Convention and twelve experimental runs of a simulation-game (The Chlorine Game; conducted in four countries, with 191 players of 59 different nationalities).<br>(cont.) The case-experience and the experimental results are analyzed using a heuristic framework developed to explore and explain strategic options available to collectives in international multilateral negotiations. Descriptively, the study concludes that the South tends to negotiate as a 'behavioral alignment' maintaining a relatively broad issue focus and investing relatively little in the internal organization. While this explains its 'lowest common denominator' tendency, it is nonetheless an understandable strategy given the South's chronic lack of resources and diversity. Prescriptively, the study suggests that the most desirable results for the South are likely to be in 'coalition mode' where the collective moves towards increased internal coordination and a more specific issue-focus. This will require concerted investment in more meaningful South-South negotiation prior to North-South negotiations and in the internal organization of the G77.<br>by Adil Najam.<br>Ph.D.

The objective of this research was to investigate alternative methods of measuring national rates of OD using publicly available data and examine the implications of using each method as a measure of performance.<br>Method. We used 7 measures to calculate deceased OD rates, based on 7 different denominators. Data were collected from OD organizations and the World Health Organization. OD rates for each measure were calculated for 10 countries for the years 2001--2004. Relative rates were calculated using Spain as the standard.<br>Results. We found variations in relative rates across the proposed measures. Regardless of the measure used Spain excelled.<br>Conclusion. If the purpose of the OD rate is to identify the top performer internationally, it may not matter which measure is used providing this is done with an understanding of its limitations.

Full textAbstract:
L’elaborato ha come tema principale l’analisi energetica di un edificio multipiano destinato a servizio residenziale – alberghiero, denominato “Terzo Millennio”.
Si tratta di una struttura con elevato fabbisogno energetico, dovendo garantire agli ospiti comfort e funzionalità dei servizi 24 ore al giorno per 365 giorni l’anno.
L’albergo è da considerarsi come un’organizzazione multifunzionale sotto il profilo tecnologico – impiantistico, economico – gestionale, con quest’ultimo avendo un ruolo fondamentale sul comportamento dei consumi energetici e alla quale è dedicato il terzo capitolo della tesi.
Un’analisi approfondita dei consumi è possibile tramite una giusta procedura e corretta metodologia di diagnosi energetica.
La raccolta dei dati necessari alla costruzione di un inventario energetico ha richiesto un lungo periodo, soprattutto la campagna di misurazione effettuata sui contattori per il gas metano e produzione d’acqua calda sanitaria per la fase di monitoraggio.
Una volta isolate le principali voci di consumo, le anomalie dovute alla gestione per il riscaldamento e una volta calcolate le dispersioni termiche, sono stati proposti interventi di miglioramento e di risparmio energetico sia dal punto di vista gestionale sia d’involucro.
Gli interventi proposti sono stati valutati utilizzando come indicatori economici il pay-back time semplice e il valore attuale netto.

Full textAbstract:
Antonio Orsini (1788-1870) è stato un importante naturalista tanto che molte specie botaniche, zoologiche e mineralogiche gli furono dedicate dai suoi colleghi scienziati. Le sue collezioni naturalistiche, comprendenti un notevole numero di reperti, dopo la morte del celebre scienziato ottocentesco, sono state soggette negli anni a numerosi trasferimenti prima di essere definitivamente collocate al terzo piano dei Musei della Cartiera Papale, nella città di Ascoli Piceno, dove sono oggi visitabili. L’erbario storico chiuso (1745-1889) denominato “Antonio Orsini”, numericamente molto consistente, non è mai stato oggetto di studi specifici. Con il presente studio di ricerca si espone il lavoro di conservazione, restauro e catalogazione dei singoli campioni d’erbario, a cui è seguita la fase di studio e rideterminazione, che hanno permesso la creazione di in un database informatico. A corredo delle ricerche più prettamente scientifiche, sono state condotte ricerche storiche su documenti d’epoca. Dallo studio svolto è emerso che all’interno dell’erbario sono presenti campioni provenienti: dall’erbario dello zio speziale i “semplici” (anni 1745, 1746 e 1747), da raccolte di Antonio Orsini, da erborizzazioni dei curatori dell’erbario successivi (anni dal 1870 fino al 1889) e da scambio. Ci sono esemplari che provengono da collezioni di botanici famosi come ad esempio Caruel, Parlatore, Tenore, Tineo Vincenzo; per cui è possibile ricostruire la fitta trama di relazioni che si è realizzata nella comunità scientifica dell’Ottocento. Notevole il contributo di Antonio Orsini alle prime due Flore storiche d’Italia di Bertoloni Antonio, (1833-1854), di Parlatore (1848-1896) ed all’unica Flora marchigiana di Paolucci (1890-1891). Dal lavoro di ricerca sono derivati numerosi dati utili da un punto di vista floristico: vi sono specie considerate estinte; prime segnalazioni dal punto di vista temporale di ritrovamento per le specie; conferme di presenze delle specie per regioni dove invece sono date per dubbie; infine exsiccata che forniscono dati nuovi utili allo studio della flora italiana con un contributo di particolare rilevanza per l’area dell’Appennino Centrale. Gli exsiccata rideterminati (n. 2281) rivestono un chiaro interesse di natura storica poiché essi sono una documentazione relativa a località ed ambienti che oggi possono essere più o meno profondamente modificati. Questa ricerca ha permesso di valorizzare un bene storico non ancora esplorato nelle sue potenzialità, con questo primo studio si rende finalmente fruibile al pubblico la ricchezza del patrimonio storico-scientifico che è contenuto nell’erbario storico “Antonio Orsini”.<br>Antonio Orsini (1788-1870) can be deemed to be a very important naturalist. He was well known in the academic circles, so that many botanical, zoological and mineralogical species were dedicated to him. His collections, including a large number of stuff, were moved to different location in the years following his death. Finally they were placed on the third floor in “Cartiera Papale Musei” in the town of Ascoli Piceno, namely his birthplace, where they are open to the public. The closed historic herbarium (1745-1889) named “Antonio Orsini”, numerically very consistent, has never been studied. This research has been conducted on several levels: the conservation, restoration and cataloging of the individual specimens; the review and the taxonomic redetermination and the creation of a computer database. Historical researches on documents of XIX Century have been done. The study of research carried out that in the Herbarium are collected exsiccata: some come from apthecary uncle’s herbarium the “simple” (years 1745, 1746 and 1747), some from Antonio Orsini himself, some from Herbarium curators (since 1870 to 1889) and others from botanic exchanges. There are many exsiccata coming from famous botanists such as Caruel, Parlatore, Tenore, Tineo Vincenzo. Thus it is possible to know the relationships among naturalists in the XIX Century scientific comunity. Antonio Orsini’s contribution to the first two Flora of Italy (Bertoloni Antonio and Parlatore) and the only one Flora of Marche (Paolucci) was very meaningful. A lot of very interesting and important floristic data are derived from this research: extinct species, the first collection in the time for the species; exsiccata referred to region where they are record as doubtful; specimens that providing new elements for the reserarch of the Italian Flora in general and in particular to the Central Appennines Area. The exsiccata examined (n. 2281) are also of historical interest because they are the real record of locations and environments that today may be more or less deeply modified. In sum, this research aims at achiving a scientific-historical dimension, as it allows everyone intetersted in this matter to understand the great richness of the Antonio Orsini’s Herbarium.

Previous issue date: 2011-12-06<br>UNISINOS - Universidade do Vale do Rio dos Sinos<br>Esta pesquisa tem por objetivo identificar as formações terminológicas que são utilizadas no contexto aplicado de uma importante empresa internacional do setor de manutenção aeronáutica, com a finalidade de obter subsídios para propor métodos de organização e padronização, uma vez que, como foi possível verificar, não existe na companhia uma terminologia estabelecida. Para isso, passamos a recolher os termos a partir de três fontes: os manuais técnicos de manutenção, o sistema de gestão informatizado, e a oralidade. É possível perceber que a variação denominativa é muito frequente. Para um único conceito é comum encontrar mais de um termo que o qualifique. Em virtude disso, voltamos nosso interesse para a busca da univocidade terminológica. A reorganização do sistema informatizado, através do desenvolvimento de um glossário para uso exclusivo dos gestores do sistema, é ponto inicial para isso. Além disso, a produção de outro glossário, para ser utilizado pelos funcionários como um instrumento de consulta, representa um acréscimo para a qualidade do trabalho. Adotamos como principal aporte teórico os fundamentos da Teoria Geral da Terminologia, porém, para a investigação do processo de formação terminológica que ocorre na empresa, também seguimos os princípios da Teoria Comunicativa da Terminologia. Para a produção dos glossários, organizamos em fichas terminológicas os termos padrão, os termos encontrados nos manuais técnicos, suas variantes denominativas, e ainda uma breve definição. De posse dos glossários, verificamos que sua aplicação para a reformulação do sistema informatizado é viável e, portanto, o objetivo de padronização é possível. Além disso, pode-se afirmar que o glossário voltado para a consulta pelos funcionários é bastante útil, pois serve para orientá-los em suas dúvidas.<br>This research paper aims to identify the terminological formations that are used in the context of an important international company of aeronautical maintenance, so that we may get subsidies to propose organizational and standardization methods, once, it was possible to verify that in the company the terminology is not totally established. To perform this, we started to collect the terms in three different sources: in the technical maintenance manuals, in the management informatics system, and the in orality. It is possible to notice that the denominative variation is really frequent. To an only concept it is normal to find different terms to describe it. Because of this, we target our attention to the objective of the terminological univocity. The informatics system reorganization, by the development of and glossary to be used by the system managers is the first step to do that. Besides, the development of another glossary, to be used by the workers as an instrument of consultation, represents an improvement to the quality of work. The study is firstly based on the theoretical assumption of General Theory of Terminology, but, to investigate the process of terminological creation that occurs in the company, we also follow the assumptions of Communicative Theory of Terminology. To the production of the glossaries, we organize, in terminological forms the standard terms, the terms that may be found in the technical manuals, the denominative variants linked to them, and, in addition, a brief definition. Once the glossaries were ready, we were able to verify that their application to the reformulation of the informatics system was viable, and so, the objectives of standardization were also viable. Besides, it is possible to assert that the glossary toward to the consultation by the workers is really useful, because it may be used to guide them and solve their doubts.

Full textAbstract:
The employment outcomes of Canadian immigrants have been deteriorating over the last two decades. Given the scope of the problem, a more systemic-based problem solving approach that involves multiple stakeholders is required to address immigrant labor market misfortunes in Canada. The Toronto Regional Immigrant Employment Council (TRIEC) has been recognized as a promising multi-stakeholder collaboration model in the area of immigrant economic integration. This study attempts to examine the conditions that contributed to the perceived success of TRIEC, with the goals being to discover critical success factors that made TRIEC a ‘success story’, and to identify lessons that could be learned by other Immigrant Employment Councils (IECs) in Canada. The study finds six success factor groups that were associated with TRIEC’s accomplishments. These include TRIEC’s highly professional operational practices, its action-oriented approach, its strong leadership model (which included business, community and municipal leaders), its focus on employers, its unique contextual environment, and its professional and highly effective communication and public relations strategies. It is argued that the last factor contributed to the formation of TRIEC’s ‘successful multi- stakeholder model’ branding in Canada and overseas.
When the strategies and activities of TRIEC were compared to those of seven other IECs in Canada, it was revealed that TRIEC was the only IEC whose leaders either were or became truly vocal on the topic of immigrant integration. It was also discovered that TRIEC was the only IEC to openly and consistently share its results, activities and finances with the general public. Finally, TRIEC was the first group in Canada and only one of IECs that managed to bring three levels of government together to discuss immigration issues. Shedding light on the role of municipalities in relation to immigrant economic integration issues, this research has shown that all the Canadian municipalities of reviewed communities were recognized by IECs for their capacity to initiate and support collaborative community efforts. The final discussion focuses on the implications of solely adopting an economic perspective in promoting the benefits of hiring immigrants to Canadian society. The study concludes that more research should be conducted to define the success of multi-stakeholder collaborations such as TRIEC, to develop appropriate frameworks to measure their effectiveness and to evaluate what degree their interventions contributed to societal change(s).

Full textAbstract:
This thesis addresses the issues of how rhythm could be taught differently in the West, how the new methodology described here could impact the performance of rhythmically complex contemporary music as well as becoming the starting point of a new creative approach for improvisers and composers. The three main goals of this research are to describe South Indian (Karnatic) rhythmical concepts which could be considered sufficiently universal to be integrated with western classical and jazz aesthetics, to show how these techniques can be utilised to analyse and perform western contemporary music with more understanding and accuracy, and to demonstrate how these concepts can be integrated within a western creative framework, be it improvised or composed.

The author has found, during her experience teaching students on the fourth grade level, that some concepts of number theory haven't even been introduced to the students. Some of these concepts include prime and composite numbers and their applications. Through personal research, the author has found that prime numbers are vital to the understanding of the grade level curriculum. Prime numbers are used to aide in determining divisibility, finding greatest common factors, least common multiples, and common denominators. Through experimentation, classroom examples, and homework, the author has introduced students to prime numbers and their applications.

Vår första cykel genomfördes i årskurs fyra, den andra cykeln i årskurs sex och den sista och avslutande cykeln i årskurs nio. Lektionen i årskurs fyra var en introduktion till bråk där fokus låg på nämnarens funktion. Lektionerna i årskurs sex och nio fokuserade till stor del på addition av bråk med olika nämnare. Processen i varje cykel började med ett förtest som sedan följdes upp med en planerad lektion utifrån utfallet, lektionen i sin tur videofilmades utifrån det iscensatta lärandeobjektet, och som sista del tog vi reda på det erfarna lärandeobjektet med hjälp av eftertest.

Our first cycle was conducted in grade four, the second cycle in grade six and the final and concluding one in grade nine. The lesson in grade four served as an introduction to fractions since the pupils were unfamiliar with the concept of fractions, yet the focus was on the function of the denominator, whereas the focus of the lessons in grade six and grade nine was on performing addition of fractions with different denominators. The process in each of the cycles in the learning study began with a pretest. The lesson was then planned according to the assumed critical aspects shown in the pretest before carried out. Each lesson was videotaped, and followed by a posttest about a week after the lesson. The material (pre-tests, lessons, and post-tests) from the three cycles were analyzed and thereafter also compared in order to find and compare critical aspects when it comes to the learning of fractions with different denominators.</p><p> </p><p>The result indicates that the critical aspects for pupils in grade four were the meaning of the denominator and the numerator and their relationship. These aspects were targeted in the lesson and the pupils’ understanding of this was improved after the lesson. Moreover, the result implies that the most important critical aspect in grade six, as well as in grade nine, appears to be to understand the proportional relationship between the denominator and the numerator. This aspect was targeted at the respective lessons, yet the pupils only showed little or even no better understanding after the lessons, and in some cases their understanding even became impaired. It appears as if the pupils in grade six and grade nine have the same difficulties when dealing with fractions with unequal denominators, and moreover they were on the same level when dealing with the fractions.</p>

The aim of this study is to investigate how the connection between fractions, decimals and percent are taught in grade 4-6 with more focuson the fractions. The empirical data was obtained by qualitative methods comprising interviews with four mathematic elementary school teachers, in addition to two observations with two classrooms in grade 6. The data presented is from one school. The theoretical framework is based on Liping Ma profound understanding of fundamental mathematics and theories of subject didactic concepts of Kilborn, Löwing, Karlsson & Kilborn and MacIntosh. The results of the interviews and observations show that the connection between fractions, decimals and percent is being taught without illuminating how the mentioned are connected. The aspect of fractions, which has been taught to show the relation between fractions and decimals, was division as metaphor. While there was no aspect of fractions has been taught to show the relation between it and percent except that a percent is a hundredth. Such as 40% is equal with 40/100. In addition, fractions has been taught by using visual aids, but never taught by using number line. In conclusion the connection between fractions, decimals and percent has not been related clearly with basic concept fractions.

Tanmateix, aquesta proposta ha rebut diverses crítiques tant en relació amb els trets utilitzats per caracteritzar tots dos tipus de neologismes, com la seva conceptualització com a categories oposades i l’exclusió o subordinació d’altres funcions dels neologismes. Per aquest motiu, el nostre objectiu consisteix a estudiar els conceptes utilitzats per caracteritzar els neologismes des del punt de vista de la seva funció, que inclou aspectes lingüístics i extralingüístics, és a dir, funcionals, sociolingüístics, discursius i pragmàtics. A partir d’aquí, dissenyem una proposta metodològica per identificar els neologismes amb valors prototípicament denominatius, estilístics, de tots dos tipus o no prototípics de cap d’aquests dos valors. Els resultats de l’anàlisi mostren que, per una banda, els criteris aïllats es complementen entre si per caracteritzar un conjunt de neologismes en relació amb la seva funció i, de l’altra, permeten observar que aquestes categories no es comporten de forma oposada ni són suficients per explicar aquest fenomen.<br>This PhD dissertation is devoted to the study of neologisms from the perspective of their communicative function. In particular, it reviews the concepts denominative neology and stylistic neology, which make up the classification most widely used to sort neologisms according to their function. However, this classification has received criticism regarding the features used to characterise both types of neologisms, their representation as opposing categories and the exclusion or subordination of other functions of neologisms. For this reason, our goal is to study the concepts used to characterise neologisms from the point of view of their function, which include linguistic and extra-linguistic aspects such as functional, sociolinguistic, discursive and pragmatic features. As a result, we have designed a methodological proposal in order to identify prototypical neologisms with either denominative or stylistic values, with both values, or with neither. The results of the analysis show that, on the one hand, the isolated criteria complement each other and they help to characterise a group of neologisms according to their function and, on the other hand, we can see that these two categories are not opposing and they are not enough to explain this phenomenon

Full textAbstract:
En 1906 le royaume de Perse connut une révolution constitutionnelle qui lui a donné la première constitution écrite du pays. Durant les années où la révolution se prépare, la société civile ouvre un grand champ d’émergence des concepts modernes du droit public. L’œuvre de l’assemblée constituante de 1906, qui a donné naissance à la constitution et à son complément, en est un exemple par excellence. Dans cette thèse nous allons procéder à l’exploitation de l’œuvre de l’assemblée constituante pour y suivre la genèse et l’évolution des concepts de droit public. Nous allons chercher à travers les concepts principaux du droit public - représentation, égalité civique et égalité devant la loi - la conception qu'avaient les constituants de la Constitution. Nous allons aussi observer la notion de constitution à certains moments décisifs de la révolution, où par exemple les révolutionnaires appelleront le roi au serment pour protéger la constitution. Dans cette thèse nous assisterons aussi à un processus qui par le biais de la redéfinition des anciens concepts de droit public, fait naître les concepts modernes du droit public. Cette thèse en se référant à l’histoire constitutionnelle du pays vise à relever un défi du droit constitutionnel d’aujourd’hui en Iran. Un droit constitutionnel qui, dès sa naissance, ne prend pas au sérieux l’histoire de la discipline. Par cette thèse nous voulons mettre en valeur l’importance et la nécessité des études historiques dans l’enseignement ainsi que dans l’étude du droit constitutionnel<br>In 1906 the Persian Kingdom witnessed a constitutional revolution which gave it its first written constitution. In the early years of the revolution, civil society opened a great field for the emergence of modern concepts of public law. The work of the Constituent Assembly of 1906, which gave birth to the Constitution and its Supplement, is a unique illustration of this. The present thesis proceeds to explain the work of the Constituent Assembly in order to follow the genesis and evolution of the principles of public law in Iran. Referring to the principal concepts of public law - representation, civic equality and equality before the law - we will attempt to find the particular conception that the constituents of the Constitution had of these concepts. We also explore the notion of constitution at certain key moments of the revolution, where, for example, the revolutionaries called the King to give oath for the safeguard of the Constitution. Further, the thesis explains the process by which modern concepts of public law were given birth through a redefinition of ancient concepts. By referring to constitutional history, the present study aims to expose the challenges to constitutional law in Iran today, a constitutional law which has failed to seriously account for the history of the discipline. The present study therefore aims to show the importance of, and need for, historical studies in the teaching and study of constitutional law in Iran

Dans cette thèse sont montrés des développements de l'approximation de la phase aléatoire (RPA) dans le contexte de théories à séparation de portée. On présente des travaux sur le formalisme de la RPA en général, et en particulier sur le formalisme "matrice diélectrique" qui est exploré de manière systématique. On montre un résumé d'un travail sur les équations RPA dans le contexte d'orbitales localisées, notamment des développements des orbitales virtuelles localisées que sont les "orbitales oscillantes projetées" (POO). Un programme a été écrit pour calculer des fonctions telles que le trou de d'échange, la fonction de réponse, etc... sur des grilles de l'espace réel (grilles parallélépipédiques ou de type "DFT"). On montre certaines de ces visualisations. Dans l'espace réel, on expose une adaptation de l'approximation du dénominateur effectif (EED), développée originellement dans l'espace réciproque en physique du solide. Également, les gradients analytiques des énergies de corrélation RPA dans le contexte de la séparation de portée sont dérivés. Le formalisme développé ici à l'aide d'un lagrangien permet une dérivation tout-en-un des termes courte- et longue-portée qui émergent dans les expressions du gradient, et qui montrent un parallèle intéressant. Des applications sont montrées, telles que des optimisations de géométries aux niveaux RSH-dRPA-I et RSH-SOSEX d'un ensemble de 16 petites molécules, ou encore le calcul et la visualisation des densités corrélées au niveau RSH-dRPA-I<br>In this thesis are shown developments in the random phase approximation (RPA) in the context of range-separated theories. We present advances in the formalism of the RPA in general, and particularly in the "dielectric matrix" formulation of RPA, which is explored in details. We show a summary of a work on the RPA equations with localized orbitals, especially developments of the virtual localized orbitals that are the "projected oscillatory orbitals" (POO). A program has been written to calculate functions such as the exchange hole, the response function, etc... on real space grid (parallelepipedic or of the "DFT" type) ; some of those visualizations are shown here. In the real space, we offer an adaptation of the effective energy denominator approximation (EED), originally developed in the reciprocal space in solid physics. The analytical gradients of the RPA correlation energies in the context of range separation has been derived. The formalism developed here with a Lagrangian allows an all-in-one derivation of the short- and long-range terms that emerge in the expressions of the gradient. These terms show interesting parallels. Geometry optimizations at the RSH-dRPA-I and RSH-SOSEX levels on a set of 16 molecules are shown, as well as calculations and visualizations of correlated densities at the RSH-dRPA-I level

abstract: With this document I will discuss and reflect upon the performance and art exhibition show which I presented as part of my MFA thesis at the MonOrchid Gallery in Phoenix, Arizona on February 10, 2017. The approach to my thesis comes from my perspective as a Hip Hop practitioner exploring the relationship between each artistic discipline that makes up Hip Hop. Through this lens I will show the knowledge that is built from both individual and the conventional collective understandings of Hip Hop. As a practitioner for over 20 years, Hip Hop has molded my mind to be multifaceted, giving me a strong interest in art making as a collaborative process. I believe the more you see the relationship between each medium, the more that connection manifests a larger cognizance for where these art forms can progress. The relationship between all of the mediums involved creates a rhythm; it is the understanding of rhythm that can connect all types of art. When you are able to understand the process of rhythm as a through line, you will be able to create from your own personal rhythmic qualities in all things. This paper will delve into how my thesis performance incorporated not only music production and dance, but the written form of Hip Hop culture (Writing), identity, and the fundamentals of design. I will use the discussion of these forms to explore the similarities of meaning in movement-making behind B-boying, the most fundamental aspect of visual art and in body forms within Hip Hop. My aim was to research what we (the dancers and myself) learned from the movement in conjunction with Writing. I will discuss how many ways this can be beneficial to exploring new interdisciplinary creative collaborations with
design, visual art, choreography, sculpture, and architecture. Rhythm is the connective tissue between these disciplines in Hip Hop culture.<br>Dissertation/Thesis<br>Masters Thesis Dance 2017

Full textAbstract:
Two-dimensional digital filters are being widely used in modern image processing software for various types of analysis. The main objective of this thesis has been to implement two-dimensional filter functions using simple design procedures such that the presence of elliptical symmetry in such designed filters are obtained by parameter modifications. In keeping with the simple design criteria, the two-dimensional filters studied in this thesis have been designed starting from a product of two one dimensional filters. Only IIR Filters have been considered for this purpose due to their flexibility in terms of altering filter parameters to obtain new filters. The filters have been checked for stability before analysis. The design has made use of the fact that varying the feedback factor ' k ' in an IIR filter produces a near-elliptical symmetric response for certain values of ' k 1 ' and ' k 2 ' having specific magnitude ranges. Considerable success has been achieved in obtained near-elliptical symmetry especially among the two-dimensional lowpass filters and also in other types of filters. It has also been found that there exists numerous possibilities to achieve near elliptical symmetry based on parameter modifications (values of k 1 and k 2 ) and magnitude range of the filter under study.

Full textAbstract:
碩士<br>國立臺中教育大學<br>數學教育學系<br>99<br>The purpose of this study was to investigate 5th graders’ concept of addition and subtraction of fraction with different types of denominator combinations. Both quantitative and qualitative methods were used in this study. First, a self-constructed paper-and-pencil test was given to all participants. Six students were chosen for semi-structured interviews based on their responses on the test. The results were as follows:
1. There are significant differences on addition and subtraction fractions with prime denominators for both algorism calculations and word problems. There is no difference on denominators with factors that were equal to or greater than 2.
2. When one denominator is the multiply of the other, students could find the common denominator easier by reading the problems, without any calculation.
3. When dealing with the prime denominators, students only use the algorism (short division) to find the common denominator, but did not understanding the meaning and/or concept of the algorism. Students could not check/find their process/errors if the problems were twisted from the example.
4. In the addition problems that two dominators had common factors equal to or greater than 2, students will multiplied two dominators directly as the common one, even with large numbers.
5. Some students could not distinguish what methods were suitable for which problems. They multiplied two denominators together as the common one in order to solve problems.

碩士<br>國立臺灣師範大學<br>資訊教育學系<br>95<br>Fractions are the first concept which children experience a number represents something other than a count. Learning of fraction is distributed from first grade to sixth grade, the significance of which is very important. According to past research, part of seniors cannot get the point of fractions. In order to help students fully understand the notion of fractions, teachers should take students’ learning difficulties into account and make up their deficiencies. Formative assessment is an effective method which help teacher to know students’ learning situation, but which is hard to apply in real teaching situation. This research combine mobile device and wireless network environment and implement an on-line formative assessment system according Ordering Theory. When the tolerance is 0.12 and the samples were within 500, the efficiency of the like denominators subtraction unit hierarchy can achieved 80%, and the accuracy can achieved 87%. This study used Chi-Square Test (Independence of Test) and two-way mixed design ANOVA to analyze data. The results showed that the effects of using on-line formative assessment to help teaching and conventional paper-and-pencil-based testing to help teaching, the learning effect of the students on like denominators subtraction unit has no significant difference.

Spillover theory was used to describe the interacting effects of the experience of living with HIV/AIDS and the experience of motherhood on one another. Findings indicate that maternal ideologies critically affected how the women experienced both their HIV-positive status and their mothering experiences. Findings also show that the mothers developed strategies to help them reconcile their valued identity as mothers with a stigmatized identity as HIV-positive women.

Full textAbstract:
abstract: Whilst linear mixed models offer a flexible approach to handle data with multiple sources of random variability, the related hypothesis testing for the fixed effects often encounters obstacles when the sample size is small and the underlying distribution for the test statistic is unknown. Consequently, five methods of denominator degrees of freedom approximations (residual, containment, between-within, Satterthwaite, Kenward-Roger) are developed to overcome this problem. This study aims to evaluate the performance of these five methods with a mixed model consisting of random intercept and random slope. Specifically, simulations are conducted to provide insights on the F-statistics, denominator degrees of freedom and p-values each method gives with respect to different settings of the sample structure, the fixed-effect slopes and the missing-data proportion. The simulation results show that the residual method performs the worst in terms of F-statistics and p-values. Also, Satterthwaite and Kenward-Roger methods tend to be more sensitive to the change of designs. The Kenward-Roger method performs the best in terms of F-statistics when the null hypothesis is true.<br>Dissertation/Thesis<br>Masters Thesis Statistics 2020

Full textAbstract:
碩士<br>亞洲大學<br>資訊工程學系碩士在職專班<br>104<br>Most of the format for computer-based testing in Taiwan is multiple choice. In spite of the advantage of automated grading, the process of solving strategies can not be analyzed. In addition to that, the possibility of guessing among the respondents is likely to happen. On the other hand, the regular test of constructed-response questions will be able to provide the respondents process of solving strategies. Likewise, correcting and grading will be a heavy task for the teachers. In this study, students’multiple-strategies, skills, and the type of error were diagnosed and classified by using the example of different denominator subtraction in math. The automated analysis processes for constructed-response questions could be formed and the cognitive diagnostic analysis was conducted by using DINA and MS-DINA modes.
The results of this study show,
1.Two or more than two solving strategies for the same question could be found. The ratio of using mixed fraction is higher than that of using improper fraction.
At the same time, the type of error is more diverse and there are lower numbers of occurrences of type of error.
2.In terms of multiple-strategies, skills, and the type of error, the coherence of experts’ grading and automated analysis processes for constructed- response questions can reach the percentage of ninety-five. Therefore, the automated analysis processes for constructed- response questions is effective.
3. Pattern correct classification rate and attribute correct classification rate in mode 2, 3, and 4 are better than those of in mode 1. Pattern correct classification rate and attribute correct classification rate in MS-DINA mode are better than those of in DINA mode.

碩士<br>臺中師範學院<br>國民教育研究所<br>91<br>A Study of Sixth Grades'''' Problem Solving Processes in Combining Unlike Denominator Fractions in Different Representation Models
Abstract
The main purpose of this study was to explore sixth grades'''' problem solving processes
in combining unlike denominator fractions in different representation models. Teaching interview method was adopted for this study. The representation models used in the contents of interview include three models - area models, discrete models, and linear models. The area models have two situations under which reference unit is dividable into a single object, or the referent unit is dividable into three objects; the discrete models have situations under which the number of referent unit is known, or the number of referent unit is unknown; the linear models also have two situations under which the length of referent unit has been metricated, or the length of referent unit has not been metricated. Each of the above interview situations is composed of six different fraction models. The subjects of the interview were sampled by levels. Five students participated in each representation model; therefore there were a total of 15 participants in the interview. Each student accepted two different interview situations of that representation model, therefore each student accepted interview two times.
It is concluded from the study results:
1. Under free solution situation, “numerator plus numerator, denominator plus denominator” strategy and common multiple calculation strategy are mainly adopted regardless of its representation model. Under restrictive graphic solution situation, six different strategies — graphic cue searching common measurement unit strategy, common multiple division referent unit strategy, graphic compensation strategy, count composition strategy, content composition strategy, and length composition strategy — appear.
2. Under both situations of the area model in which the referent unit is dividable into single object and the linear model in which the length of referent unit has not been metricated, the students can search the common measurement unit of two resultants through graphic cues in particular fraction model.
3. In the fraction composition solution strategy, the students are affected by its fraction concept. The students who successfully solved the question possess some fraction concepts such as part-whole, portioning, unitizing, and equivalence etc.; while the students whole failed to resolve the question lack of the above said fraction concepts.
Key words: unlike denominator composition, area model, discrete model, linear model, solution strategy, common measurement unit
