During the Middle and Late Neolithic, especially in south-eastern Sweden, the archaeological material sometimes reveals a type of hybrid ceramic that was previously classified as a Battle-axe ceramic. But as recent as the latter part of the 1990s, this hybrid pottery was again noticed by researchers in a compilation of Neolithic pottery. In this compilation, the name Third Group is used as a collective name for the hybrid ceramics. Further studies have since resulted in a relatively restrictive template with several subgroups where the material has been defined as the Third Group. This work is a type of definition analysis with an element of comparative analysis where the use of the term Third Group is analyzed, as well as the definition behind the term. The main goal of the study is that during the relatively short period the term has been in use, be able to follow and gain a deeper understanding of how words and definitions in technical language are used, developed, and discussed. The aim of the study is to show that communication and language use within one's own profession is extremely relevant for further research.

Jag, Therese Enebrant, läser pedagogiskt drama 51-60p på Malmö Högskola, 2006. Denna c-uppsats har jag valt att kalla "Pedagogiskt drama på Montessoriskolor". Mitt syfte med studien är att undersöka vilka möjligheter det finns i att kombinera pedagogiskt drama med Montessoripedagogiken. Mina frågeställningar är:• Går det att kombinera pedagogiskt drama med Montessoripedagogiken och i så fall hur? • Vad innebär pedagogiskt drama för pedagogerna på Montessoriskolorna? • Vad vill man uppnå med att använda pedagogiskt drama i undervisningen och vilken inställning har kollegerna till ovanstående?• Hur kan jag dra nytta av resultaten i min framtida profession?De metoder som jag har använt mig av är intervju samt observationer. Jag har intervjuat pedagoger som arbetar med barn från 3 års ålder och upp till 12 år. Barnen kommer från två Montessoriskolor. Mitt resultat visar att alla pedagogerna som jag har intervjuat tycker att barnen utvecklas personligt samt i grupp med hjälp av pedagogiskt drama. Det har också kommit fram att det är en oslagbar kombination att kombinera pedagogiskt drama med Montessoripedagogiken. / Teachers´ Stories About the Combining Pedagogical Drama with the Montessori Educational Method

This thesis is devoted to the study of operators on discrete structures. The operators are supposed to be self-adjoint and obey a certain translation invariance property. The discrete structures are given as Cayley graphs via finitely generated groups. Here, sofic groups and amenable groups are in the center of our considerations. Note that every finitely generated amenable group is sofic. We investigate the spectrum of a discrete self-adjoint operator by studying a sequence of finite dimensional analogues of these operators. In the setting of amenable groups we obtain these approximating operators by restricting the operator in question to finite subsets Qn , n ∈ N. These finite dimensional operators are self-adjoint and therefore admit a well-defined normalized eigenvalue counting function. The limit of the normalized eigenvalue counting functions when |Qn | → ∞ (if it exists) is called the integrated density of states (IDS). It is a distribution function of a probability measure encoding the distribution of the spectrum of the operator in question on the real axis. In this thesis, we prove the existence of the IDS in various geometric settings and for different types of operators. The models we consider include deterministic as well as random situations. Depending on the specific setting, we prove existence of the IDS as a weak limit of distribution functions or even as a uniform limit. Moreover, in certain situations we are able to express the IDS via a semi-explicit formula using the trace of the spectral projection of the original operator. This is sometimes referred to as the validity of the Pastur-Shubin trace formula. In the most general geometric setting we study, the operators are defined on Cayley graphs of sofic groups. Here we prove weak convergence of the eigenvalue counting functions and verify the validity of the Pastur-Shubin trace formula for random and non-random operators . These results apply to operators which not necessarily bounded or of finite hopping range. The methods are based on resolvent techniques. This theory is established without having an ergodic theorem for sofic groups at hand. Note that ergodic theory is the usual tool used in the proof of convergence results of this type. Specifying to operators on amenable groups we are able to prove stronger results. In the discrete case, we show that the IDS exists uniformly for a certain class of finite hopping range operators. This is obtained by using a Banach space-valued ergodic theorem. We show that this applies to eigenvalue counting functions, which implies their convergence with respect to the Banach space norm, in this case the supremum norm. Thus, the heart of this theory is the verification of the Banach space-valued ergodic theorem. Proceeding in two steps we first prove this result for so-called ST-amenable groups. Then, using results from the theory of ε-quasi tilings, we prove a version of the Banach space-valued ergodic theorem which is valid for all amenable groups. Focusing on random operators on amenable groups, we prove uniform existence of the IDS without the assumption that the operator needs to be of finite hopping range or bounded. Moreover, we verify the Pastur-Shubin trace formula. Here we present different techniques. First we show uniform convergence of the normalized eigenvalue counting functions adapting the technique of the Banach space-valued ergodic theorem from the deterministic setting. In a second approach we use weak convergence of the eigenvalue counting functions and additionally obtain control over the convergence at the jumps of the IDS. These ingredients are applied to verify uniform existence of the IDS. In both situations we employ results from the theory of large deviations, in order to deal with long-range interactions.

Die Arbeit enthaelt kurze Abrisse zum gegenwertigen Kenntnisstand bezueglich der Struktur und der Eigenschaften von amorphen Siliciumdioxiden sowie zur Erzeugung von Silan- und Phenylgruppen auf Siliciumdioxidoberflaechen. Im Mittelpunkt der Arbeit steht die Oberflaechenfunktionalisierung des Aerosil 300 aus der Gasphase bei hohen Temperaturen. Es wird die Reaktion des Wasserstoffs mit den Silanolgruppen zu Silangruppen und deren Umsetzung mit Benzol untersucht. Die IR-Spektroskopie wird zur Verfolgung des Einflusses der Reaktionsparameter (Temperatur, Zeit und Volumenstroeme der Gase) auf das Ergebnis der Funktionalisierung eingesetzt. Neben der IR-Spektroskopie wird auch die Festkoerper-NMR-Spektroskopie zur Strukturaufklaerung genutzt. Weiterhin werden die erzeugten Oberflaechengruppen quantitativ bestimmt und die molaren dekadischen Extinktionskoeffizienten fuer die Valenzschwingung der Silangruppen bei 2293 cm-1 und der Phenylgruppen bei 3068 cm-1 berechnet. Die Hydrolysebestaendigkeit sowie die thermische Stabilitaet der Oberflaechensilane und -phenyle wird ueberprueft. Außerdem werden Aussagen zu den Eigenschaften der Oberflaechen-Si-H-Bindung getroffen. Dann wird gezeigt, daß auch auf Kieselgeloberflaechen Silan- und Phenylgruppen erzeugt werden koennen.

Diese Dissertation untersucht Galois-Erweiterungen von Zahlkörpern und die Unverzweigte Fontaine-Mazur-Vermutung für p-adische Galois-Darstellungen und deren Verallgemeinerungen. Wir beweisen viele grundlegende Fälle der Vermutung und liefern einige nützliche Kriterien zur Überprüfung. Darüber hinaus schlagen wir mehrere verschiedene Strategien vor, um die Vermutung anzugreifen und auf einige spezielle Fälle zu reduzieren. Wir beweisen auch viele neue Ergebnisse der Vermutung im zweidimensionalen Fall. Als Anwendung beweisen wir die Endlichkeit der unverzweigten Galois-Deformationsringe unter der Annahme eines speziellen Falles der Vermutung und geben einige Gegenbeispiele zur sogenannten Dimension-Vermutung für Galois-Deformationsringe unter der Annahme der Vermutung. / This thesis studies Galois extensions of number fields, and the Unramified Fontaine-Mazur Conjecture for p-adic Galois representations and its generalizations. We prove many basic cases of the conjecture, and provide some useful criterions for verifying it. In addition, we propose several different strategies to attack the conjecture and reduce it to some special cases. We also prove many new results of the conjecture in the two-dimensional case. As an application, we prove the finiteness of unramified Galois deformation rings assuming a special case of the conjecture, and we give some counterexamples to the so-called dimension conjecture for Galois deformation rings assuming the conjecture.

The diversification of unicellular, auto- and heterotrophic protists and the appearance of multicellular microorganisms is recorded in numerous Tonian age successions worldwide, including the Visingsö Group in southern Sweden. The Tonian Period (1000-720 Ma) was a time of changes in the marine environments with increasing oxygenation and a high input of mineral nutrients from the weathering continental margins to shallow shelves, where marine life thrived. This is well documented by the elevated level of biodiversity seen in global microfossil record. The Visingsö Group contains a taxonomically rich assemblage of cyanobacteria, stromatolites, algal phytoplankton, and vase-shaped microfossils. A new study of organic-walled, phytoplanktic microfossils, which are extracted by palynological method from the Visingsö 1 borehole samples, reveals the presence of morphologically disparate taxa. They are in gross cysts of microalgae (Pterospermopsimorpha, Pterospermella, Cerebrosphaera, Trachysphaeridium, Simia and certain Leiosphaeridia with pylome) and some are of uncertain affinities (acritarchs). Representative taxa of two lineages among green algae, Prasinophyceae and Chlorophyceae, are recognized. Cyanobacterial clusters and filaments are abundant and specimens of multicellular, yet systematically unrecognized taxa are recorded. Taxonomically, the assemblage is similar to some from other successions distributed along the margins of Baltica, Laurentia and Siberia in the Tonian Period. The ecological habitats of those organisms are inferred by comparing with their potential modern analogues and from the sedimentological setting of the upper formation of the Visingsö Group. / Denna studie handlar om biodiversiteten och den biologiska affiniteten av mikrofossil från den neoproterozoiska eran, tonianperioden (1000-720 Ma). De har extraherats från övre formationen av Visingsögruppen i södra Sverige.Mikrofossilen har organiska cellväggar, är encelliga och har förmodats representera algcystor (resistenta reproduktiva strukturer), cyanobakterier, och andra organismer av okänd tillhörighet. Neoproterozoikum har den högsta graden av biologisk diversitet under prekambrium. Det är därför viktigt att studera diversiteten för att förstå utvecklingen av biosfären under denna period i samband med utvecklingen av miljöer. Den studerade samlingen härrör från ett borrhål på Visingsö i Vättern, och visar på större diversitet än från tidigare studier.Denna nya studie syftar till att bestämma biodiversiteten i den övre formationen av Visingsögruppen och att känna igen affiniteten av mikrofossilen med organiska väggar och deras ekologi. Vissa av de undersökta mikrofossilen hör sannolikt till grönalgerna. Kluster och fiber av cyanobakterier är rikligt förekommande, och några prover är ej biologiskt igenkännbara. Med hjälp av moderna analoger och sedimentologiska data är ekologin hos dessa mikrofossil utläs

Challenges in global politics like climate change, maritime piracy and fighting highly contagious diseases concern global public goods. The related policy decisions are mostly made by teams. In contrast, economic models of global public goods typically assume a single rational decision-maker. We use a laboratory experiment to compare team decisions to decisions of individuals in a finitely repeated public good game with and without a costly punishment option. Teams of three participants coordinate on decisions either by majority or unanimity rule. We find that in absence of a punishment option teams contribute more to the public good than individuals. With a punishment option subsequently to the contribution decision team treatments exhibit a less frequent use of anti-social punishment and lower levels of social as well as anti-social punishment. Extreme preferences for punishment are eliminated by the majority decision rule. Overall, team decisions are closer to the social optimum and teams yield higher net payoffs when compared to individuals.

Diese Dissertation befasst sich mit dem oft vernachlässigten Problem ethnischer Gruppen, die eine Delegitimierung ihrer Staatsbürgerschaft erfahren haben. Sie gelten nicht als „richtige“ Staatsbürger eines Nationalstaates, da sie nicht der ethnischen Definition der Nation entsprechen. Staatsbürgerschaft entsteht im Zuge der Bildung von Nationalstaaten in einem modernen Weltsystem, das nach wie vor kolonial geprägt ist. Die Legitimität dieser globalen kolonialen Idee des Nationalstaates basierte auf dem kulturellen Konzept einer Nation; der Illusion einer homogenen gemeinsamen Vergangenheit, gemeinsamer Gebräuche und einer gemeinsamen Sprache, in der Unterschiede unterdrückt werden. Auf diesem Modell basiert die Idee eines legitimen Bürgers. Illegitime Staatsbürgerschaft ist eine andere Art und Weise, eine koloniale Staatsbürgerschaft zu benennen, die in ein eurozentrisches, patriarchalisch/weiß und christlich zentriertes Weltsystem eingebettet ist. Staatsbürgerschaft ist ein Konzept, das sich auf Individuen bezieht. Durch Rassializierung und Ethnisierung wird dem Mensch seine Individualität genommen. Der rassifizierte -illegitime Bürger wird stets als Teil einer Gruppe beschrieben; die "Einwanderer", die "Muslime", die "Indigenen", die "Inder des Nordostens". Sie werden nie als autonomes individuelles Subjekt beschrieben. Diese Individualität ist den weißen europäischen oder europäischen Nachkommen vorbehalten und wird als "weißes Privileg" bezeichnet. Diese Dissertation beschreibt, wie ähnlich die illegitime Staatsbürgerschaft in zwei unterschiedlichen Ländern empirisch operiert, die beide eine koloniale, untergeordnete Position im Weltsystem einnehmen. Die untersuchten Gruppen – die Mapuche in Chile und die Menschen im Nordosten Indiens – leiden unter einer doppelten Kolonialisierung. Zum einen aufgrund der Position von Chile und Indien im Weltsystem, zum anderen bezüglich der geringen Wertschätzung innerhalb des Nationalstaates. / This thesis tackles the commonly overlooked issue of ethnic groups that have suffered a delegetimization of their citizenship. They are not considered as the ideal citizens of a nation-state because they do not conform ethnically to the definition of the nation. Citizenship emerges with the formation of the nation-state in a modern world system characterized by a still operating coloniality. The legitimacy of this global colonial idea of nation-state was based on the cultural concept of a nation; an illusion of a homogenous shared past, customs and language where differences were suppressed. This is the common pattern of nation-state formation and the rise of the idea of a legitimate citizen. Illegitimate citizenship is another way of naming a colonial citizenship inserted in a Eurocentric patriarchal/white and Christian-centered world-system. Citizenship is a concept referring to individuals, however, and when it is racialized or ethnicized, the individuality of the person is taken away. The racialized citizen, the illegitimate citizen is always described as part of a group; the “immigrants”, the “Muslims”, the “indigenous”, the “northeastern Indians”. They are never described as an autonomous individual subject. This individuality is reserved for white European or European- descendant people and has been coined as “white privilege”. This research describes how illegitimate citizenship empirically operates in a very similar way in two ethnic groups within two different countries that have in common a colonial subordinated position in the world system. Therefore, Mapuches in Chile and Northeastern Indians suffer a double colonization in two different scales; one regarding the position of Chile and India in the world-system and one regarding their own position within the nation-state.

In this work the methods of mode decomposition and Fourier analysis of quantum fields on curved spacetimes previously available mainly for the scalar fields on Friedman-Robertson-Walker spacetimes are extended to arbitrary vector fields on general spatially homogeneous spacetimes. This is done by developing a rigorous unified framework which incorporates mode decomposition, harmonic analysis and Fourier analysis. Explicit constructions are performed for a variety of situations arising in homogeneous cosmology. A number of results concerning classical and quantum fields known for very restricted situations are generalized to cover almost all cosmological models.
