Lo scopo di questo lavoro è la generalizzazione, nel contesto degli 1-motivi, degli accoppiamenti di altezza costruiti da B. Mazur e J. Tate sulle varietà abeliane. Seguendo il loro approccio, consideriamo ρ-splittings della biestensione di Poincaré di un 1-motivo e richiediamo che siano compatibili con la linearizzazione canonica associata alla biestensione. Stabiliamo quindi risultati riguardanti l'esistenza di tali ρ-splittings. Quando ρ è non ramificato, tale risultato segue se l'accoppiamento di monodromia dell’1-motivo preso in considerazione è non degenere. Per ρ ramificato, il ρ-splitting si costruisce a partire da una coppia di scissioni delle filtrazioni di Hodge delle realizzazioni di de Rham dell’1-motivo e del suo duale. In questo modo generalizziamo precedenti risultati di R. Coleman and Y. Zarhin sulle varietà abeliane. Questi ρ-splittings vengono poi usati per definire un accoppiamento globale sui punti razionali di un 1-motivo e del suo duale. Infine forniamo accoppiamenti locali tra i zero-cicli e i divisori di una varietà, applicando i risultati precedenti ai suoi 1-motivi di Picard e d’Albanese.The purpose of this work is to generalize, in the context of 1-motives, the height pairings constructed by B.

Sozeri, Baris. "Motivational Factors Affecting Spectators." Master's thesis, METU, 2005. http://etd.lib.metu.edu.tr/upload/2/12606891/index.pdf.
Full textAbstract:
Interest in sport, especially in soccer has been increasing in Turkey. Consequently, sport clubs should ascertain the reasons why people attend sporting events and what motivates them to attend in order not to lose their interest. From this pointthe purpose of this study was to examine the motivational factors affecting spectator attendance of soccer games in Turkey. In order to measure the sport fan motivations of the spectators, the Turkish version of Motivational Scale for Sport Consumption (MSSC) was distributed to 602 spectators in three different Super League Soccer games with the systematic sampling procedure. Results of this study indicated that the physical skills of the athletes, aesthetics related with the game of soccer and the achievement motives are the most effective motives in explaining spectators&rsquo
decisions to attend soccer games in Turkey. On the other hand, escape, drama, and social interaction motives were found to be the least important motives of the Turkish soccer spectators. The findings of this study also revealed that the more frequent ticket consumers&rsquo
achievement and acquisition of knowledge motivations were higher than the other consumer types in spectator segmentation. Multiple regression analysis revealed that 27 % of the variance in future ticket consumption intentions can be accounted for by the linear combination of 6 of the 12 variables including past ticket consumption frequency, fan identification with the team, and the motives of achievement, acquisition of knowledge, aesthetics, and social interaction. These findings indicated that Turkish spectators are mainly motivated by the core product of the sport, the game itself. However, previous studies indicated that overarching motives (escape, social interaction) should be one of the aspects of the game attendance. Thus, findings of this study showed that Turkish spectators do not perceive the attending a sport game as a social and stress releasing activity. In conclusion, motivations are the needs of the sport consumers, therefore, Turkish sport clubs should try to fulfill the needs of their customers, in this case, acquiring skilled soccer players, playing good team soccer, and playing combatively to win games should be the prerequisites of the sport clubs to not to lose their spectators&rsquo
interest in following their team from the stadium.

Cakmak, Sabiha Safak. "Psychometric Properties Of Anxiety Sensitivity Index-revised And The Relationship With Drinking Motives And Alcohol Use In Turkish University Students And Patients." Master's thesis, METU, 2006. http://etd.lib.metu.edu.tr/upload/12607321/index.pdf.
Full textAbstract:
Anxiety Sensitivity (AS) consists of beliefs that the experience of anxiety symptoms leads to illness or additional anxiety. The aim of the present study was to examine the factor structure of the Turkish version of Anxiety Sensitivity Index–
Revised (ASI-R), and to investigate associations among AS, alcohol use and drinking motives in university students and alcohol dependent inpatients. The participants were 411 university students (225 females and 186 males) and 55 (3 females and 52 males) alcohol dependent inpatients. All participants were administered ASI-R, State-Trait Anxiety Inventory-Trait Form, Beck Depression Inventory, Drinking Motives Questionnaire-Revised, and Demographic Information Form. Exploratory factor analyses revealed four lower order factors of the ASI-R: (1) fear of respiratory symptoms
(2) fear of cardiovascular symptoms
(3) fear of cognitive dyscontrol
and (4) fear of publicly observable anxiety symptoms. ANOVA revealed that the frequency and amount of alcohol use were significantly higher in male students than females. Males reported more alcohol use for Coping and Conformity Motives than did females. Regression analyses revealed that only fear of cognitive dyscontrol significantly predicted hazardous alcohol use of students. Coping Motives significantly predicted alcohol use after controlling the effects of demographics, depression and ASI-R lower order factors in students using alcohol. Fear of publicly observable anxiety symptoms significantly predicted frequency of alcohol use in students using alcohol. Students reported using alcohol mostly for Enhancement, Social, Coping, and Conformity Motives, respectively. Students with high AS reported more alcohol use for Coping, Social and Conformity Motives than those with moderate and low AS. Fear of cognitive dyscontrol and fear of publicly observable anxiety symptoms explained a significant variance of drinking motives in students. In alcohol dependent inpatients, only fear of respiratory symptoms had a significant correlation with Coping Motives. Patients reported having used alcohol mostly for Coping, Enhancement, Social, and Conformity Motives, respectively. Coping and Enhancement Motives were significantly correlated with alcohol use. Results were discussed within the findings in the literature.

Artusa, Marco. "Sur des théorèmes de dualité pour la cohomologie condensée du groupe de Weil d'un corps p-adique." Electronic Thesis or Diss., Bordeaux, 2024. http://www.theses.fr/2024BORD0228.
Full textAbstract:
L’objectif de cette thèse est double. Premièrement, on construit une théorie de cohomologie topologique pour le groupe de Weil d’un corps p-adique. En second lieu, on utilise cette théorie pour prouver des théorèmes de dualité, qui se manifestent sous la forme de la dualité de Pontryagin entre groupes abéliens localement compacts. Ces résultats améliorent des théorèmes de dualité existants et leur confèrent une perspective topologique. De tels objectifs peuvent être atteints grâce aux Mathématiques Condensées, qui fournissent un cadre dans lequel il est possible de faire de l’algèbre avec des objets topologiques. On définit une théorie cohomologique pour les groupes condensés et pro-condensés et on étudie ses propriétés. Ensuite, on applique cela au groupe de Weil d’un corps p-adique, considéré comme un groupe pro-condensé. On démontre que, dans certains cas particuliers, les groupes de cohomologie correspondants sont des groupes abéliens localement compacts de rangs finis. Ceci nous permet d’étendre la dualité locale de Tate à une catégorie plus générale de coefficients non nécessairement discrets, o`u elle prend la forme d’une dualité de Pontryagin entre groupes abéliens localement compacts. Dans la dernière partie de la thèse, on utilise le même cadre pour retrouver une version “à la Weil” de la dualité de Tate avec coefficients dans les variétés abéliennes, et plus généralement dans les 1- motifs, en exprimant ces dualités comme des accouplements parfaits entre groupes abéliens condensés. Pour ce faire, on associe à chaque groupe algébrique, resp. 1-motif, un groupe abélien condensé, resp. un complexe de groupes abéliens condensés, avec une action du groupe de Weil (pro-condensé). On appelle cette association la réalisation de Weil-étale condensée. On montre l’existence d’un accouplement de Poincaré condensé pour les variétés abéliennes, et on prouve une version condensée et “à la Weil” de la dualité de Tate à coefficients dans les variétés abéliennes, qui améliore le résultat correspondant de Karpuk. Enfin, on montre l’existence d’un accouplement de Poincaré condensé pour les 1-motifs. On prouve que cet accouplement est compatible à la filtration par les poids et on démontre un théorème de dualité à coefficients dans les 1- motifs, qui améliore un résultat de Harari-SzamuelyThe goal of this thesis is twofold. First, we build a topological cohomology theory for the Weil group of p-adic fields. Secondly, we use this theory to prove duality theorems for such fields, which manifest as Pontryagin duality between locally compact abelian groups. These results improve existing duality theorems and give them a topological flavour. Condensed Mathematics allow us to reach these objectives, providing a framework where it is possible to do algebra with topological objects. We define and study a cohomology theory for condensed groups and pro-condensed groups, and we apply it to the Weil group of a p-adic field, considered as a pro-condensed group. The resulting cohomology groups are proved to be locally compact abelian groups of finite ranks in some special cases. This allows us to enlarge the local Tate duality to a more general category of non-necessarily discrete coefficients, where it takes the form of a Pontryagin duality between locally compact abelian groups. In the last part of the thesis, we use the same framework to recover a Weil-version of the Tate duality with coefficients in abelian varieties and more generally in 1-motives, expressing those dualities as perfect pairings between condensed abelian groups. To do this, we associate to every algebraic group, resp. 1-motive, a condensed abelian group, resp. a complex of condensed abelian groups, with an action of the (pro-condensed) Weil group. We call this association the condensed Weil-´etale realisation. We show the existence of a condensed Poincar´e pairing for abelian varieties and we prove a condensed-Weil version of the Tate duality with coefficients in abelian varieties, which improves the correspondent result of Karpuk. Lastly, we exhibit a condensed Poincar´e pairing for 1-motives. We show that this pairing is compatible with the weight filtration and we prove a duality theorem with coefficients in 1-motives, which improves a result of Harari-Szamuely

Institut für Regional- und Umweltwirtschaft, WU Vienna University of Economics and Business, 2009. http://epub.wu.ac.at/1658/1/document.pdf.
Full textAbstract:
Traditionally, regional endowments are viewed as external variables when it comes to location choices of companies. In most concepts on location choices and regional economics companies are thought to view the local labour market, the local innovation system or the general quality of life in a region as given and chose the location that best suits the company's needs. Increasingly however, scholars from different research fields are providing arguments to reverse that view and show that there can be good reasons for a company to engage in improving its location despite implicit externalities. In this paper we try to systematically analyse issue of corporate engagement in regions. We will show how strong and in which fields companies engage in their respective region, how this engagement can be related to their existing regional integration and what differences appear between industries and types of companies in this respect. In this study we draw upon extensive interviews with over thirty companies from three industrial sectors in the Austrian region of Styria: the metals industry, which dates back to medieval times and has gone through a deep process of economic restructuring, the automotive industry, the first industry in which a comprehensive cluster policy approach was applied in Austria and the software industry, a rather young industry that experienced high growth rates in the past years. We will conclude that even though there are differences between the industries and types of companies in terms of scope and scale of regional integration and regional engagement, there is a strong correlation between the two: the higher the regional integration, the higher corporate regional engagement and vice versa.Series: SRE - Discussion Papers

One of the cornerstones of the R system for statistical computing is the
multitude of contributed packages making an extremely broad range of
statistical techniques and other quantitative methods freely available. This
study investigates which factors are the crucial determinants responsible for
the participation of the package authors in the R project. For this purpose a
survey was conducted among R package authors, collecting data on different
types of participation in the R project, three psychometric scales (hybrid
forms of motivation, work design characteristics, and values), as well as
various specie-demographic factors. These data are analyzed using item
response theory and generalized linear models, showing that the most important
determinants for participation are a hybrid form of motivation and the
knowledge characteristics of the work design. Other factors are found to have
less impact or influence only specific aspects of participation. (authors' abstract)Series: Research Report Series / Department of Statistics and Mathematics

Full textAbstract:
Children and adolescents are now using online communication to form and/or maintain relationships with strangers and/or friends. Relationships in real life are important for children and adolescents in identity formation and general development. However, social relationships can be difficult for those who experience feelings of loneliness and social anxiety. The current study aimed to replicate and extend research conducted by Valkenburg and Peter (2007b), by investigating differences in online communication patterns between children and adolescents with and without selfreported loneliness and social anxiety. Six hundred and twenty-six students aged 10-16 years completed a questionnaire survey about the amount of time they engaged in online communication, the topics they discussed, who they communicated with, and their purposes of online communication. Following Valkenburg and Peter (2007b), loneliness was measured with a shortened version of the UCLA Loneliness Scale (Version 3) developed by Russell (1996), whereas social anxiety was assessed with a sub-scale of the Social Anxiety Scale for Adolescents (La Greca & Lopez, 1998). The sample was divided into four groups of children and adolescents: 220 were “non-socially anxious and non-lonely”, 139 were “socially anxious but not lonely”, 107 were “lonely but not socially anxious”, and 159 were “lonely and socially anxious”. A one-way ANOVA and chi-square tests were conducted to evaluate the aforementioned differences between these groups. The results indicated that children and adolescents who reported being lonely used online communication differently from those who did not report being lonely. Essentially, the former communicated online more frequently about personal things and intimate topics, but also to compensate for their weak social skills and to meet new people. Further analyses on gender differences within lonely children and adolescents revealed that boys and girls communicated online more frequently with different partners. It was concluded that for these vulnerable individuals online communication may fulfil needs of self-disclosure, identity exploration, and social interactions. However, future longitudinal studies combining a quantitative with a qualitative approach would better address the relationship between Internet use and psychosocial well-being. The findings also suggested the need for further exploration of how such troubled children and adolescents can use the Internet beneficially.

Full textAbstract:
Gambling becomes a source of difficulties of varying severity for some individuals whereas it is a positive experience for most of other people. Although gambling continues to be an entertaining activity for the majority of gambling individuals, prevalence rates suggest that pathological gambling is not low compared to other types of diagnosis. Most of the data with respect to gambling is from Western gambling literature, whereas research investigating the associated features of problem and pathological gamblers are very limited in the Turkish sample. The present study aimed to adapt two gambling-related instruments into Turkish and subsequently to examine the contributory roles of gambling participation, personality, affect, cognition, and motives of Turkish gamblers on gambling severity and gambling-related harm. The present study sample consisted of 357 males who were gambling in the sports and horse-races betting terminals. The findings pointed out it is important to conduct gambling research with Turkish samples considering the gambling severity and harm scores of the participants. The Turkish versions of Gambling-Related Cognitions Scale and Gambling Motives Scale showed promising psychometric properties with respect to their reliability and validity analyses. Besides, relatively higher negative affect, neuroticism, gambling-related cognitions, avoidance motive, and gambling participation were found to be associates of probable pathological gambling among Turkish regular gambling individuals. Moreover, the relationships of gambling cognitions / motives and gambling severity were mediated by the gambling participation. The main findings and related findings of the present study together with their implications are reported and discussed within the relevant gambling literature.

In this essay I want to illuminate how teachers describe their work to increase motivation for reading in first grade. The teachers views on the concept of motivation and its complexes. Relevant research shows that there is a clear link between pupils learning and their motivation.
The purpose of this essay is to contribute with knowledge about how teachers describe their work to increase pupils’ motivation for reading in first grade.
The survey was conducted during the latter part of autumn -09 and the method that was used was qualitative interviews. Three teachers with long experience of first grade were each interviewed.
The results showed that all the teachers found it difficult to concretely explain their views on the concept of motivation. According to the three informants this is rarely discussed in school. They shared a perception that motivation was found inside each pupil and that it could be satisfied in different ways. The teachers also described how they worked to increase pupils' motivation for reading. A few points they described and felt were important to pupils' motivation for reading was; the reading aloud importance, good reading - role models, the reading–book instruments and a books content.

Syftet med den här studien är att undersöka hur tre lärare i årskurs 1 arbetar med läsmotivation. Vidare är syftet att undersöka om pojkar och flickor motiveras till läsning på samma sätt. Läsförmåga är en förutsättning för att kunna leva och verka i ett samhälle, eftersom läsning är centralt i människors liv. Det framgår dock av PIRLSresultat från 2016 att flickor presterar bättre än pojkar när det kommer till läsning. Jag vill därför undersöka hur lärare motiverar elever till läsning. Den här studien baseras på tre observationer och tre intervjuer med yrkesverksamma lärare. Observationerna dokumenteras i observationsscheman utifrån bestämda händelser, och intervjuerna spelas in och transkriberas. Resultatet visar att flickor och pojkar generellt inte motiveras till läslust på samma sätt. Det som motiverar elever till läsning är individuellt och beror inte på kön. Elever motiveras till läsning genom att lärare bland annat förklarar nyttan av att kunna läsa samt genom att eleverna själva får välja böcker.

A segurança alimentar e as consequências provocadas no meio ambiente
pelo modo de produção atual de alimentos, baseado no uso de agrotóxicos e alto
grau de mecanização, têm se tornado temas de debates na comunidade
internacional. Diante desse cenário, o modelo de produção orgânico, que tem na
isenção de insumos químicos e na preservação do ecossistema seus valores
fundamentais, surge como uma proposta alternativa. O mercado de produtos
orgânicos apresentou crescimento considerável na última década no Brasil. O
objetivo deste trabalho foi levantar os motivos que influenciam consumidores na
sua decisão de compra de produtos orgânicos. Foi utilizado um método de
pesquisa do tipo survey, de cunho exploratório e descritivo, com amostra de 44
indivíduos, frequentadores de feiras e de lojas especializadas. A coleta de dados se
deu através de um formulário com escalas desenvolvidas para indicar os possíveis
fatores que influenciam a compra de produtos orgânicos no Rio de Janeiro, a
partir de revisão bibliográfica. As ferramentas estatísticas utilizadas para o
tratamento dos dados foram a análise descritiva e o teste de diferença de médias
entre consumidores assíduos e não regulares, com ou sem filhos, considerando
diferentes faixas etárias. Os resultados apontam que as principais motivações para
a compra de orgânicos são a isenção de agrotóxicos e os benefícios à saúde do
consumidor e de sua família. Porém, preço e proximidade das feiras às residências
dos consumidores surgiram como fatores relevantes para o desenvolvimento deste
mercado.Food safety and the impact in the environment caused by the current food production based on the use of pesticides and high degree of mechanization have become topics of discussion in the international community. Given this scenario, the organic production model, which has chemical inputs and exemption in the preservation of the ecosystem their fundamental values, emerges as an alternative proposal. The organic products market showed considerable growth over the past decade in Brazil. The aim of this work was to raise the reasons which influence consumers to purchase organic products. It was used a research method called survey, of exploratory and descriptive nature, with 44 individuals, fairs and specialty stores visitors. Data collection took place through a form with scales developed to indicate the possible factors influencing purchase of organic products in Rio de Janeiro, from literature review. The statistical tools used for the processing of data were descriptive analysis and testing of average difference between regular and non-regular consumers, with or without children, considering different age groups. The results show that the main reasons for buying organic are the exemption of pesticides and the benefits to the health of the consumer and of his family. However, price and proximity of the fairs to consumer homes have emerged as important factors for the development of this market.

Studiens syfte är att undersöka hur lärare i årskurs 1–3 säger sig arbeta med skönlitteratur i undervisningen för att stimulera elevernas inre och yttre motivation till läsning. Den metod som användes för att samla in material är semistrukturerade intervjuer. Intervjuer gjordes med fem lärare som arbetar i årskurs 1–3. Utgångspunkten för studien är tidigare forskning om läsmotivation samt teorier om begreppen inre och yttre motivation. Resultatet visar att lärarna arbetar på många olika sätt för att öka elevernas läsmotivation. De använder olika läsutmaningar för att eleverna ska läsa mer och de samtalar med dem om varför det är viktigt att läsa. Däremot visar resultatet att lärarna inte fokuserar på begreppen inre och yttre motivation i någon större utsträckning. Resultatet visar också de svårigheter lärarna möter i arbetet när de ska motivera eleverna till läsning. Lärarna berättade att en del elever inte har någon läskultur hemifrån och att vårdnadshavarna inte är stöttande när det kommer till läsning. Detta anser lärarna vara ett problem då det kan vara svårt att få dessa elever motiverade till läsning.

Full textAbstract:
Forskning visar på att elever i grundskolan påvisar bristande motivation när det kommer till läsning och att deras läsvanor har försämrats. När läsning väl förekommer är det till största delen som tidsfördriv, där elever enbart bläddrar i böcker. När lärare har slut på idéer eller lektionsslut börjar närma sig är det oftast läsning elever får fördriva tiden med. Läsning förekommer mestadels i sammanhang där elever förväntas utveckla sin läsförmåga. Syftet med kunskapsöversikten är att ta reda på vad forskning säger om hur lärare kan motiverar elever till läsning, mer specifikt svara på frågeställningen: Hur kan lärare motivera elever till att läsa i årskurs 1-3? För att besvara frågeställningen för kunskapsöversikten har vetenskapliga studier om motivation, läsning och professionella lärare sökts upp som empiriskt material. Detta gjordes genom både manuella och systematiska sökningar i olika databaser. Styrdokument nämns ocksåi bakgrunden för att tydliggöra vad som förväntas av lärare. Forskningen som togs fram analyserades utifrån tematisk innehållsanalys och sammanställdes sedan under lämpliga underrubriker i resultatdelen. Resultatet i kunskapsöversikten visar på att en läskultur är väldigt viktigt för att elever ska bli läsare, där de får uppleva läsande förebilder både i och utanför skolan. Vidare visar resultatet att själva litteraturen elever får till sig att läsa, spelar stor roll för själva motivationen. Slutligen visar det också att lärare behöver bemöta elever på rätt sätt. Genom att stötta elever utifrån bakgrund, erfarenheter och hemmiljö kan elevers motivation öka.

A análise de dois romances de Rachel Jardim, Vazio pleno: relatório do cotidiano (1976) e Inventário das cinzas (1980), demonstra a ênfase das obras em um caráter intimista. Tal aspecto se manifesta por meio da exploração do espaço biográfico – o qual se evidencia nas implicações da incorporação na diegese de traços autobiográficos – e também se exprime através dos elementos que instauram uma dialética entre o binômio exterior/interior. Este estudo é baseado no levantamento e na análise de elementos estruturais e de temas comuns às obras, o que promoveu a elaboração de um processo metodológico projetado sobre a distribuição dos dados em “células” e “motivos”. Esses motivos convergem para dois grandes blocos, chamados “células”, que, juntos, formam um mosaico de assuntos itemizados os quais orbitam o intimismo. A análise detalhada das duas células é distribuída em dois capítulos com os títulos de Traços autobiográficos e A dialética exterior/interior. Em vista de que o conceito de intimismo, ainda pouco explorado pela historiografia literária brasileira, recebe diferentes nomenclaturas, busco defini-lo, bem como delimitar as suas principais características. Enfoco, também, de que forma o romance de artista e alguns aspectos atinentes à estética romântica, associados à escrita do eu, emolduram o corpus, sobretudo no que respeita à tematização dos processos que envolvem a leitura e a escrita literárias. A análise fundamenta-se em conceitos fornecidos pela Teoria Literária e reflexões de distintos teóricos, não só no que concerne ao intimismo na Literatura Brasileira, mas também ao espaço ocupado por Rachel Jardim na História da Literatura Brasileira. Os procedimentos analíticos mostram o vínculo das obras de Rachel Jardim estudadas com o veio intimista no âmbito do sistema literário brasileiro.
The analysis of two novels by Rachel Jardim, Vazio pleno: relatório do cotidiano (1976) e Inventário das cinzas (1980) aims at demonstrating the emphasis of these works on an intimist character. Such an aspect arises throughout the exploration of the biographical space – which becomes evident in the implications of the incorporation of autobiographical traces in the narrative tissue – and also springs up throughout the elements that establish a dialectical relationship within the pair exterior/interior. The present work is based on the survey and the analysis of structural elements and common themes found in the two novels, fact that supported the elaboration of a methodological process designed on the distribution of the data in “cells” and “motives”. These motives are gathered in two blocks, called “cells”, which unite to form a mosaic made of itemized matters that revolve around intimacy. The detailed analysis of the two cells is distributed in two chapters under the titles of Traços autobiográgicos and A dialética exterior/interior. Due to the fact that the concept of intimacy, still slightly investigated by the literary Brazilian historiography, receives many different names, we look forward to its definition as well as to the demarcation of its main features. We also focus on the ways the artist novel and some principles of the Romantic aesthetics related to the writing of the “I” frame the corpus mainly in what concerns the thematization of the pertinent procedures linked to the literary acts of reading and writing. The analysis is grounded on concepts taken from the Literary Theory and from distinct theorist ́s stands not only in what concerns to intimacy in Brazilian Literature but also related to Rachel Jardim ́s place within the Brazilian literary history. The analytical proceedings show the connection between Rachel Jardim ́s works and the intimist thread in literature within the scope of the literary Brazilian system.

Full textAbstract:
Syftet med studien är att belysa lärares uppfattningar om hur digitala verktyg kan bidra till motivation hos elever i den tidiga skrivutvecklingen i årskurs 1. Studiens resultat är baserat på en enkätundersökning med 92 deltagande lärare samt en systematisk litteraturstudie med tidigare forskning utifrån studiens utvalda kategorier. Enkätundersökningen består av både kvalitativa och kvantitativa frågor. Studien utgår från det sociokulturella perspektivet med inriktning mot begreppet mediering där en analysprocess används för att analysera studiens resultat. Studien har även sin utgångspunkt i motivationsteorin som fokuserar på hur individen blir motiverad och av vad. I resultatet jämförs enkätsvaren med den systematiska litteraturstudien för att se eventuella likheter och skillnader. Studiens resultat visar att digitala verktyg ofta används i skrivundervisningen men att tillgången till digitala resurser varierar i skolorna vilket kan vara ett hinder för många i undervisningen. Resultatet visar även att 78 av 92 deltagande lärare anser att digitala verktyg motiverar eleverna till att skriva. I studien beskrivs digitala verktyg i form av Ipads och datorer vilket är de vanligast förekommande verktygen i klassrummet.

Syftet med studien är att få ökad kunskap om lärares uppfattningar om och undervisning i läsning kopplat till motivation, i årskurs 1. För att undersöka detta ligger fokus på vilken läsundervisning lärare bedriver och vad lärare använder för motiverande inslag i sin läsundervisning. Teoretiska utgångspunkter som används i studien är The Simple View of Reading och förväntan-värdeteorin. Data består av intervjuer och observationer med fyra lärare. I resultatet framkommer det att majoriteten av lärarna bedriver läsundervisning där olika läsundervisningsmetoder kombineras och att elevers motivation är betydelsefullt för läsutvecklingen. Resultatet visar även att lärarna använder en mängd motiverande inslag i läsundervisningen som går att härleda till förväntan-värdeteorin.

Full textAbstract:
There is a wonderful conjecture of Bloch and Kato that generalizes both the analytic Class Number Formula and the Birch and Swinnerton-Dyer conjecture. The conjecture itself was generalized by Fukaya and Kato to an equivariant formulation. In this thesis, I provide a new proof for the equivariant local Tamagawa number conjecture in the case of Tate motives for unramified fields, using Iwasawa theory and (φ,Γ)-modules, and provide some work towards extending the proof to tamely ramified fields.

Gealy, Matthew Thomas. "On the Tamagawa Number Conjecture for Motives Attached to Modular Forms." Thesis, 2006. https://thesis.library.caltech.edu/5020/1/thesis-final.pdf.
Full textAbstract:
We carry out certain automorphic and l-adic computations, the former extending results of Beilinson and Scholl, and the latter using ideas of Kato and Kings, related to explicit motivic cohomology classes on modular varieties. Under mild local and global conditions on a modular form, these give exactly the coordinates of the Deligne and l-adic realizations of said motivic cohomology class in the eigenspace attached to the modular form (Theorem 4.1.1). Assuming Kato's Main Conjecture and a Leopoldt-type conjecture, we deduce (a weak version of) the Tamagawa Number Conjecture for the motive attached to a modular form, twisted by a negative integer.

Mohamed, Mohamed Nazir Riad. "Influence of virtual world end-user motives on social capital." Thesis, 2017. https://researchonline.jcu.edu.au/51750/1/51750-mohamed-thesis-2017.pdf.
Full textAbstract:
This virtual platform study enhances the building of stronger social communities. It researches the influence of end-user motives on social relationship dimensions by highlighting the mediating pathways of social connectivities. Developers and businesses can enlist the findings to customise their virtual end-user-targeted solutions and then deliver value-added virtual services and products.
The relationship between end-user motives and the formation of social capital remains critical in understanding casual influences; however, there has been no previous research looking at this relationship by considering social connectivities. Previous research on end-user motives and social capital within one type of online gaming environment indicated some driving factors behind the development and formation of social capital in virtual worlds.
This study focuses on active end-users participating in one of three substantive virtual world platforms to examine whether end-user motives influence their social capital dimensions.
Three basic theories—gratification, social relationship and social capital—underpin this study's social capital motives model. In this model, end-user motive antecedents— achievement, control, escapism and friendship—are linked to social connectivities through bridging and bonding, which, in turn, are linked to the social capital's cognitive, relational and structural dimensions.
An online global survey in English provided 274 valid and usable cases from three different virtual worlds.
A quantitative approach is used to test the proposed research framework model. The resulting empirically tested social capital motives model was bootstrap-validated using AMOS 22. The model delivered a high-quality fit across all relevant fit indices.
The social capital motives model verified 12 hypothesised paths as significant and theoretically justified. Here, achievement and escapism show a significant positive effect on bridging social connectivities, whereas control, escapism and friendship show a significant positive effect on bonding social connectivities.
Next, bridging social connectivities shows a strong positive effect on bonding social connectivities. Bridging social connectivities also offers a positive influence on cognitive social capital. Bonding social connectivities positively affects cognitive, relational and structural social capital dimensions. Finally, both the cognitive and structural dimensions are found to have a significant effect on the resulting relational social capital dimension.
The social capital motives model contributes to research within international business (particularly virtual world businesses and social media) and information technology platforms. Theoretically, this study's two-stage Structural Equation Modelling (SEM) path model integrates three theories and redefines bonding and bridging as social connectivities.
This study shows end-user motives can indirectly influence social capital dimensions through social connectivities. Thus, researchers investigating the formulation of social capital in virtual worlds can apply the social capital motives model as a starting point when developing their more advance social capital research models.
Businesses can engage the social capital motives model to further motivate their end-users to generate greater social capital, which, in turn, will strengthen interactions among existing end-users and, consequently, attract new end-users.

Full textAbstract:
Although the term "Art Lover" is something that our society uses in everyday language, little is known about what this term means. How do museum visitors characterize the Art Lover? How does an Art Lover's experience of art differ from that of a Non-Art Lover? In answering these two questions, this study seeks to understand a museum visitor's self-identification as an Art Lover and the role that this identification plays in the quality of their museum experience. Using a framework of Ethnomethodology and Marketing Research techniques, a written questionnaire consisting of thirty-five questions was administered. In April 2003, over one-hundred visitors to the Montreal Museum of Fine Art completed the questionnaire. Seven visitors participated in follow-up interviews. It was found that 22% of museum attendees in this study do not consider themselves Art Lovers. Analysis of both questionnaire and interview results revealed that all participants--regardless of their love for art--shared many of the same responses, emotions, and behaviours. However, in comparing the experiences of Art Lovers to Non-Art Lovers, a marked difference was found in the relative intensities and values associated with these motives, emotions, and behaviours. Art Lovers expressed a high level of intensity in their desire to seek out museum experiences and subsequently reported an elevated level of satisfaction with their experience of the exhibition. The results of this study suggest that to consider oneself an Art Lover is directly and positively related to the quality of an individual's museum experience. This study also suggests that a significant proportion of museum visitors are people who do not consider themselves Art Lovers and that museums need to better address this segment of their public.

This paper is focused on tempo and motive transformations in Ernest Bloch's Violin Sonata No.1. I document the life, background, and style of the composer and his music. In the second part, I analyze the structure of motives, and its interaction with tempo changes. I attempt to find out the most appropriate performance according to my analysis.
