In recent years many teachers and students have begun having good access to digital technology in their classrooms, and in the context of Sweden the majority of secondary schools are known as one-to-one schools, with students having their own computer or tablet. However, the mere presence of technology in the classroom is not a guarantee for improved teaching and learning. In fact, there is a challenge involved with integrating technology in the classroom and many teachers need support. Therefore, the aim of this thesis is to contribute to the knowledge about support for teachers integrating digital technology, especially a classroom response system (CRS), in the mathematics classroom. This is done by focusing on frameworks for CRS task design and technology integration. The thesis consists of two papers and a kappa. Both papers use data from a design research project including interventions in two cases. Paper I focuses on the development of design principles and task types for CRS tasks in a multiple-choice format aiming to engineer mathematical classroom discussions. The study generated three design principles, six task types, and 31 empirically evaluated tasks. The empirical evaluation shows that teachers consider the evaluated CRS tasks useful for engineering mathematical classroom discussions. Paper II focuses on exploring the potential of Ruthven’s (2009) SFCP framework as tool for analyzing empirical data in order to conceptualize and analyze teachers’ reasoning about critical aspects of technology integration in the mathematics classroom. The results show that the SFCP framework can be useful for capturing teachers’ reasoning about critical aspects of technology integration, but also that the framework does not capture teachers’ reasoning about students’ attitudes and behaviors. Therefore, the framework would benefit from taking into consideration students’ attitudes and behaviors, as these features are a challenge teachers need to deal with when integrating technology in the classroom. This thesis kappa, building on earlier research as well as the results and methods of its own papers, ends with an elaborated discussion on the challenges and support for teachers wanting to integrate CRS in their mathematics classroom. / Lärare och elever har idag god tillgång till digital teknik i klassrummen. I Sverige är numera majoriteten av högstadie- och gymnasieskolorna en-till-en skolor där alla elever har en egen dator eller surfplatta. Blotta närvaron av digital teknik i klassrummen är inte en garanti för förbättrad undervisning och ökat lärande. I själva verket så är det en utmaning att integrera digital teknik i klassrummet och många lärare behöver stöd för att lyckas med detta. Syftet med den här uppsatsen är att bidra till kunskap om stöd för lärare som integrerar digitala verktyg i matematikklassrummet. Detta görs dels genom att fokusera på ramverk för att konstruera matematikuppgifter till digitala responssystem och dels genom att undersöka ett ramverk för teknikintegrering i undervisningen. Uppsatsen består av två artiklar och en kappa. Båda artiklarna använder data från ett designforskningsprojekt bestående av interventioner i två separat fall. Artikel I fokuserar på utvecklingen av designprinciper och uppgiftstyper för flervalsuppgifter till digitala responssystem. Uppgifterna syftar till att initiera och fördjupa matematiska diskussioner i klassrummet. Studien genererade tre designprinciper, sex uppgiftstyper och 31 empiriskt utvärderade flervalsuppgifter som kan användas för att välja, värdera och konstruera uppgifter till responssystem. Den empiriska utvärderingen visar att lärarna anser att de testade uppgifterna och uppgiftstyperna är användbara för att initiera matematiska klassrumsdiskussioner. Artikel II fokuserar på att undersöka potentialen av Ruthvens (2009) ramverk ”Structuring Features of Classroom Practice” (SFCP), som ett analytiskt verktyg för att begreppsliggöra och analysera lärares resonemang om kritiska aspekter vid teknikintegrering i matematikklassrummet. Resultatet visar att ramverket är användbart för att fånga lärares resonemang om kritiska aspekter vid teknikintegrering i undervisningen, men också att ramverket inte fångade lärares resonemang om elevers attityder och uppförande. Studien föreslår att ramverket kan utvecklas och förbättras genom att även ta hänsyn till elevernas attityder och uppförande, eftersom detta är kritiska aspekter som lärare behöver hantera när de integrerar teknik i klassrummet. Med utgångspunkt från tidigare forskning och resultaten i artiklarna avslutas uppsatsens kappa med en utvecklad diskussion om utmaningar och stöd för lärare som integrerar digitala responssystem i matematikklassrummet.

The role of the Anthropic Principle in astrophysics and cosmology is examined in two principal parts. The first (minor) part takes a chiefly philosophical perspective and examines the manner in which human cognition features into discussions on cosmic origins. It is shown that the philosophical questions raised by the Anthropic Principle and ‘fine-tuning of life’ bear resemblances to problems within the philosophy of mind and we seek a common origin for this surprising parallel. A form of ‘epistemic structural realism’ is defended and used to critique the physicalist identity thesis. It is argued that equating ‘reality’ with mathematical structures, which is the basis of the identity thesis, leads to incoherent conclusions. Similar reasoning is used to critique infinite Multiverse theories. In the second (major) part, we gradually transition into mainstream astrophysics, first presenting a new line of research to explore counterfactual universes using semi-analytic models (SAMs) and offering a preliminary study wherein the cosmological constant is varied and the effects on ‘advanced civilisations’ are examined. The importance of galaxy mergers is highlighted and leads to their study. We first try solving the pattern-recognition problem of locating mergers using the Galaxy Zoo database and produce the largest homogenous merger catalogue to date. We examine their properties and compare them with the SAMs of the Millennium Simulation finding good general agreement. We develop the Galaxy Zoo approach with a new visual-interface design and double the size of the merger catalogue of SDSS mergers in the local Universe.

This dissertation examines Cassell's theory of purchasing power parity within the context of post-World War II foreign exchange markets and government policies.

In accordance with structural theory and distributive justice theory, this study investigates if Americans' personal encounters with the opportunity structure and their existing reward conditions will influence their perceptions toward distribution outcomes in the U.S. I argue that higher-status individuals possessing various "attributes of structural privilege" will exhibit less support for regulating income inequality in society than lower-status individuals. Upward mobility should also be negatively related to support for restoring greater equality in allocation outcomes. However, the effect of mobility on justice perceptions should vary by class status, since class has been known to be a reliable predictor of these attitudes. The study employed a sample of 438 American adults from the GSS 2000 dataset, and ordinary least squares (OLS) regression was applied in the analyses of the data. Two of the three above hypotheses received partial confirmation, that is, there were class, race, and gender differences in distributive justice perceptions. Class also interacted significantly with occupational mobility in altering distributive justice perceptions.

Arnold Schoenberg viewed himself as an extension of the German Romantic tradition. Schoenberg's early unpublished songs prove his indebtedness to nineteenth century music, but they also show a great deal that is strictly Schoenbergian. This paper investigates the musical elements that Schoenberg assimilated from tradition, especially from the great Lied tradition of the nineteenth century. lements that may be associated with his later works are also investigated, namely the 2rundgestalt principle, and his use of the "primal cell," a trichord set that appears in works of all his periods. This paper shows how these elements are manifested in seven early songs. These songs are from the Nachod collection, an assemblage of correspondence and early unpublished music manuscripts by Schoenberg. This collection is owned by North Texas State University.

The electricity network is undergoing significant changes in the transition to a low carbon system. The growth of renewable distributed generation (DG) creates a number of technical and economic challenges in the electricity network. While the development of the smart grid promises alternative ways to manage network constraints, their impact on the ability of the network to accommodate DG – the ‘hosting capacity’- is not fully understood. It is of significance for both DNOs and DGs developers to quantify the hosting capacity according to given technical or commercial objectives while subject to a set of predefined limits. The combinational nature of the hosting capacity problem, together with the intermittent nature of renewable generation and the complex actions of smart control systems, means evaluation of hosting capacity requires appropriate optimisation techniques. This thesis extends the knowledge of hosting capacity. Three specific but related areas are examined to fill the gaps identified in existing knowledge. New evaluation methods are developed that allow the study of hosting capacity (1) under different curtailment priority rules, (2) with harmonic distortion limits, and (3) alongside energy storage systems. These works together improve DG planning in two directions: demonstrating the benefit provided by a range of smart grid solutions; and evaluating extensive impacts to ensure compliance with all relevant planning standards and grid codes. As an outcome, the methods developed can help both DNOs and DG developers make sound and practical decisions, facilitating the integration of renewable DG in a more cost-effective way.

The goal of this thesis is to give an exposition of the following recent result of Freeman, Lennard, Odell, Turett and Randrianantoanina. A Banach space has the Schur property if and only if every weakly compact set is contained in the closed convex hull of a weakly null sequence. This result complements an old result of Grothendieck (now called the Grothendieck Compactness Principle) stating that every norm compact subset of a Banach space is contained in the closed convex hull of a norm null sequence. We include many of the relevant definitions and preliminary results which are required in the proofs of both of these theorems.

Throughout the course of this thesis, we give an introduction to optimal control theory and its necessary conditions, prove Pontryagin's Maximum Principle, and present the life-cycle saving under uncertain lifetime optimal control problem. We present a very involved sensitivity analysis that determines how a change in the initial wealth, discount factor, or relative risk aversion coefficient may affect the model the terminal depletion of wealth time, optimal consumption path, and optimal accumulation of wealth path. Through simulation of the life-cycle saving under uncertain lifetime model, we are not only able to present the model dynamics through time, but also to demonstrate the feasibility of the model.

in English The diploma thesis addresses the precautionary principle and its role in environmental protection. In the introduction the author deals with the origins of application of this principle, its definition and its primary characteristics. Precautionary principle is distinguished from prevention principle and differences between terms principle and approach are assessed. Subsequently the thesis describes the current state of incorporation of precautionary principle in the individual areas of environmental protection and specifies the typology of various incorporation methods. Furthermore, significant case law regarding the subject principle is introduced and the current importance of the principle is evaluated. Substantial arguments of precautionary principle critics are also included. In the final part of the thesis, the author outlines de lege ferenda ideas concerning the precautionary principle, including efficient methods of incorporation of the principle, solutions to flaws of current regulations and draft of template provisions of precautionary principle application.

Parallel imports and trademark law in the Czech Republic This thesis goal is to provide a basic introduction to Czech trademark law and to analyse parallel imports. I wanted to emphasize the "exhaustion of rights "principle in the context of the law of the European Union also in the context of law in the Czech Republic. It covers some of the most intriguing aspects of parallel imports for example "placed on the market", "consent of a trade mark owner", "repackaging and other changed of the parallel imported goods "by examining the most important Court of Justice of the European Union (before European Court of Justice) decisions that have set a solid legal environment and use them to explain how parallel imports have evolved. The thesis focuses on Czech and European trademark law and parallel imports in the law of the Czech Republic, as a member state of European Union. At the first part of thesis I explain what is trademark law, it's sense and intent in general. I also examine the fundamental sources of Czech national trademark law, trademark law of the European Union and international law. Which is followed by description what a "trademark" is and which trademarks are protected in Czech Republic, their functions and "trademark owners" as a basics terminology of trademark law in Czech Republic.
