New media reading strategy

This dissertation addresses the need for a strategy that will help readers new to new media texts interpret such texts. While scholars in multimodal and new media theory posit rubrics that offer ways to understand how designers use the materialities and media found in overtly designed, new media texts (see, e.g,, Wysocki, 2004a), these strategies do not account for how readers have to make meaning from those texts. In this dissertation, I discuss how these theories, such as Lev Manovich’s (2001) five principles for determining the new media potential of texts and Gunther Kress and Theo van Leeuwen’s (2001) four strata of designing multimodal texts, are inadequate to the job of helping readers understand new media from a rhetorical perspective. I also explore how literary theory, specifically Wolfgang Iser’s (1978) description of acts of interpretation, can help audiences understand why readers are often unable to interpret the multiple, unexpected modes of communication used in new media texts. Rhetorical theory, explored in a discussion of Sonja Foss’s (2004) units of analysis, is helpful in bringing the reader into a situated context with a new media text, although these units of analysis, like Iser’s process, suggests that a reader has some prior experience interpreting a text-as-artifact. Because of this assumption of knowledge put forth by all of the theories explored within, I argue that none alone is useful to help readers engage with and interpret new media texts. However, I argue that a heuristic which combines elements from each of these theories, as well as additional ones, is more useful for readers who are new to interpreting the multiple modes of communication that are often used in unconventional ways in new media texts. I describe that heuristic in the final chapter and discuss how it can be useful to a range of texts besides those labelled new media.

Economic viability of shale gas production in the Marcellus Shale; indicated by production rates, costs and current natural gas prices

The U.S. natural gas industry has changed because of the recent ability to produce natural gas from unconventional shale deposits. One of the largest and most important deposits is the Marcellus Shale. Hydraulic fracturing and horizontal drilling have allowed for the technical feasibility of production, but concerns exist regarding the economics of shale gas production. These concerns are related to limited production and economic data for shale gas wells, declines in the rates of production, falling natural gas prices, oversupply issues coupled with slow growth in U.S. natural gas demand, and rising production costs. An attempt to determine profitability was done through the economic analysis of an average shale gas well using data that is representative of natural gas production from 2009 to 2011 in the Marcellus Shale. Despite the adverse conditions facing the shale gas industry it is concluded from the results of this analysis that a shale gas well in the Marcellus Shale is profitable based on NPV, IRR and breakeven price calculations.

The Domestic Natural Gas Shortage in China

This thesis analyzes the domestic shortage in the Chinese natural gas market. Both the domestic supply and demand of natural gas are growing fast in China. However, the supply cannot catch up with the demand. Under the present pricing mechanism, the Chinese natural gas market cannot get the equilibrium by itself. Expensive imports are inadequate to fill the increasing gap between the domestic demand and supply. Therefore, the shortage problem occurs. Since the energy gap can result in the arrested development of economics, the shortage problem need to be solved. This thesis gives three suggestions to solve the problem: the use of Unconventional Gas, Natural Gas Storage and Pricing Reform.

Phenotyping, functional characterization, and developmental changes in canine intestinal intraepithelial lymphocytes

Little is currently known about the lymphocyte populations in the normal and diseased canine gut. The aim of this study was thus the phenotypical and functional characterization of canine intestinal intraepithelial lymphocytes (IEL). IEL were isolated from full-thickness biopsies of 15 adult Swiss Beagle dogs (mean age 8.2 +/-2.8 years) and compared to mesenteric lymph node cells. The phenotypical characterization by multi-parameter flow cytometry revealed that canine IEL differ substantially from lymph node T cells, and consist of various unconventional lymphocyte subsets, unique to mucosal surfaces. These include gammasigma T cells, and CD4(-)CD8(-) and CD8alphaalpha(+) T cells. IEL populations in adult dogs were also compared to those isolated from neonatal Beagle dogs. Analysis revealed a high frequency of undifferentiated CD4(-)CD8(-) T cells in newborn dogs whereas mature CD4(+) and CD8(+) T cells predominate in adult dogs, indicating maturation of the intestinal immune system during development. As IEL in other species are thought to exhibit regulatory functions, we investigated the role of IEL on the activation-induced proliferation of lymph node T cells. While IEL alone did not show activation-induced proliferation, they significantly inhibited the proliferation of activated lymph node T cells in a cell number-dependent manner. These findings are the first to demonstrate that canine intestinal IEL have an immunoregulatory phenotype, which may contribute to the maintenance of intestinal immune homeostasis and may, therefore, be lost in canine chronic enteropathies.

T cell-mediated immunoregulation in the gastrointestinal tract

In the intestinal tract, only a single layer of epithelial cells separates innate and adaptive immune effector cells from a vast amount of antigens. Here, the immune system faces a considerable challenge in tolerating commensal flora and dietary antigens while preventing the dissemination of potential pathogens. Failure to tightly control immune reactions may result in detrimental inflammation. In this respect, 'conventional' regulatory CD4(+) T cells, including naturally occurring and adaptive CD4(+) CD25(+) Foxp3(+) T cells, Th3 and Tr1 cells, have recently been the focus of considerable attention. However, regulatory mechanisms in the intestinal mucosa are highly complex, including adaptations of nonhaematopoietic cells and innate immune cells as well as the presence of unconventional T cells with regulatory properties such as resident TCRgammadelta or TCRalphabeta CD8(+) intraepithelial lymphocytes. This review aims to summarize the currently available knowledge on conventional and unconventional regulatory T cell subsets (Tregs), with special emphasis on clinical data and the potential role or malfunctioning of Tregs in four major human gastrointestinal diseases, i.e. inflammatory bowel diseases, coeliac disease, food allergy and colorectal cancer. We conclude that the clinical data confirms some but not all of the findings derived from experimental animal models.

Direct Democracy: Protest Catalyst or Protest Alternative?

This paper presents the first investigation of whether direct democracy supplements or undermines the attendance of demonstrations as a form of protest behavior. A first approach assumes that direct democracy is associated with fewer protests, as they function as a valve that integrates voters’ opinions, preferences, and emotions into the political process. A competing hypothesis proposes a positive relationship between direct democracy and this unconventional form of political participation due to educative effects. Drawing on individual data from recent Swiss Electoral Studies, we apply multilevel analysis and estimate a hierarchical model of the effect of the presence as well as the use of direct democratic institutions on individual protest behavior. Our empirical findings suggest that the political opportunity of direct democracy is associated with a lower individual probability to attend demonstrations.

Ultracold Quantum Gases and Lattice Systems: Quantum Simulation of Lattice Gauge Theories

Abelian and non-Abelian gauge theories are of central importance in many areas of physics. In condensed matter physics, AbelianU(1) lattice gauge theories arise in the description of certain quantum spin liquids. In quantum information theory, Kitaev’s toric code is a Z(2) lattice gauge theory. In particle physics, Quantum Chromodynamics (QCD), the non-Abelian SU(3) gauge theory of the strong interactions between quarks and gluons, is nonperturbatively regularized on a lattice. Quantum link models extend the concept of lattice gauge theories beyond the Wilson formulation, and are well suited for both digital and analog quantum simulation using ultracold atomic gases in optical lattices. Since quantum simulators do not suffer from the notorious sign problem, they open the door to studies of the real-time evolution of strongly coupled quantum systems, which are impossible with classical simulation methods. A plethora of interesting lattice gauge theories suggests itself for quantum simulation, which should allow us to address very challenging problems, ranging from confinement and deconfinement, or chiral symmetry breaking and its restoration at finite baryon density, to color superconductivity and the real-time evolution of heavy-ion collisions, first in simpler model gauge theories and ultimately in QCD.

Quantum and classical criticality in a dimerized quantum antiferromagnet

A quantum critical point (QCP) is a singularity in the phase diagram arising because of quantum mechanical fluctuations. The exotic properties of some of the most enigmatic physical systems, including unconventional metals and superconductors, quantum magnets and ultracold atomic condensates, have been related to the importance of critical quantum and thermal fluctuations near such a point. However, direct and continuous control of these fluctuations has been difficult to realize, and complete thermodynamic and spectroscopic information is required to disentangle the effects of quantum and classical physics around a QCP. Here we achieve this control in a high-pressure, high-resolution neutron scattering experiment on the quantum dimer material TlCuCl3. By measuring the magnetic excitation spectrum across the entire quantum critical phase diagram, we illustrate the similarities between quantum and thermal melting of magnetic order. We prove the critical nature of the unconventional longitudinal (Higgs) mode of the ordered phase by damping it thermally. We demonstrate the development of two types of criticality, quantum and classical, and use their static and dynamic scaling properties to conclude that quantum and thermal fluctuations can behave largely independently near a QCP.

Novel unsymmetrically functionalized BEDT–TTF derivatives: synthesis, crystal structure and electrochemical characterization

Novel functionalized bis(ethylenedithio)tetrathiafulvalene (BEDT–TTF) derivatives 4 and 5 have been synthesized in good yields from cyano precursor via a cross-coupling reaction. Their redox potentials have been studied by cyclic voltammetry in a dichloromethane solution; this indicated that they are slightly weaker electron donors than BEDT–TTF. Compound 4 has been studied by X–ray crystallography; this revealed that, in the crystal, the molecules were held together by some unconventional C–H···N and C–H···S hydrogen bonds.

Evidence for C−H⋅⋅⋅O Hydrogen Bond Assisted Recognition of a Pyrimidine Base in the Parallel DNA Triple-Helical Motif

The efficient recognition of the pyrimidine base uracil by hypoxanthine or thymine in the parallel DNA triplex motif is based on the interplay of a conventional N−H⋅⋅⋅O and an unconventional C−H⋅⋅⋅O hydrogen bond.

Finding a voice - Nollywood inspired filmmaking practices in Switzerland

Under the name Nollywood a unique video film industry has developed in Nigeria in the last few decades, which now forms one of the world’s biggest entertainment industries. With its focus on stories reflecting „the values, desires and fears” (Haynes 2007: 133) of African viewers and its particular way of production, Nollywood brings „lived practices and its representation together in ways that make the films deeply accessible and entirely familiar to their audience“ (Marston et al. 2007: 57). In doing so, Nollywood shows its spectators new postcolonial forms of performative self‐expression and becomes a point of reference for a wide range of people. However, Nollywood not only excites a large number of viewers inside and outside Nigeria, it also inspires some of them to become active themselves and make their own films. This effect of Nigerian filmmaking can be found in many parts of sub‐Saharan Africa as well as in African diasporas all over the world – including Switzerland (Mooser 2011: 63‐66). As a source of inspiration, Nollywood and its unconventional ways of filmmaking offer African migrants a benchmark that meets their wish to express themselves as minority group in a foreign country. As Appadurai (1996: 53), Ginsburg (2003: 78) and Marks (2000: 21) assume, filmmakers with a migratory background have a specific need to express themselves through media. As minority group members in their country of residence they not only wish to reflect upon their situation within the diaspora and illustrate their everyday struggles as foreigners, but to also express their own views and ideas in order to challenge dominant public opinion (Ginsburg 2003: 78). They attempt to “talk back to the structures of power” (2003: 78) they live in. In this process, their audio-visual works become a means of response and “an answering echo to a previous presentation or representation” (Mitchell 1994: 421). The American art historian Mitchell, therefore, suggests interpreting representation as “the relay mechanism in exchange of power, value, and publicity” (1994: 420). This desire of interacting with the local public has also been expressed during a film project of African, mainly Nigerian, first-generation migrants in Switzerland I am currently partnering in. Several cast and crew members have expressed feelings of being under-represented, even misrepresented, in the dominant Swiss media discourse. In order to create a form of exchange and give themselves a voice, they consequently produce a Nollywood inspired film and wish to present it to the society they live in. My partnership in this on‐going film production (which forms the foundation of my PhD field study) allows me to observe and experience this process. By employing qualitative media anthropological methods and in particular Performance Ethnography, I seek to find out more about the ways African migrants represent themselves as a community through audio‐visual media and the effect the transnational use of Nollywood has on their form of self‐representations as well as the ways they express themselves.

Polaronic metal state at the LaAlO₃/SrTiO₃ interface

Interplay of spin, charge, orbital and lattice degrees of freedom in oxide heterostructures results in a plethora of fascinating properties, which can be exploited in new generations of electronic devices with enhanced functionalities. The paradigm example is the interface between the two band insulators LaAlO3 and SrTiO3 that hosts a two-dimensional electron system. Apart from the mobile charge carriers, this system exhibits a range of intriguing properties such as field effect, superconductivity and ferromagnetism, whose fundamental origins are still debated. Here we use soft-X-ray angle-resolved photoelectron spectroscopy to penetrate through the LaAlO3 overlayer and access charge carriers at the buried interface. The experimental spectral function directly identifies the interface charge carriers as large polarons, emerging from coupling of charge and lattice degrees of freedom, and involving two phonons of different energy and thermal activity. This phenomenon fundamentally limits the carrier mobility and explains its puzzling drop at high temperatures.

First Staphylococcal Cassette Chromosome mec Containing a mecB-Carrying Gene Complex Independent of Transposon Tn6045 in a Macrococcus caseolyticus Isolate from a Canine Infection.

A methicillin-resistant mecB-positive Macrococcus caseolyticus (strain KM45013) was isolated from the nares of a dog with rhinitis. It contained a novel 39-kb transposon-defective complete mecB-carrying staphylococcal cassette chromosome mec element (SCCmecKM45013). SCCmecKM45013 contained 49 coding sequences (CDSs), was integrated at the 3' end of the chromosomal orfX gene, and was delimited at both ends by imperfect direct repeats functioning as integration site sequences (ISSs). SCCmecKM45013 presented two discontinuous regions of homology (SCCmec coverage of 35%) to the chromosomal and transposon Tn6045-associated SCCmec-like element of M. caseolyticus JCSC7096: (i) the mec gene complex (98.8% identity) and (ii) the ccr-carrying segment (91.8% identity). The mec gene complex, located at the right junction of the cassette, also carried the β-lactamase gene blaZm (mecRm-mecIm-mecB-blaZm). SCCmecKM45013 contained two cassette chromosome recombinase genes, ccrAm2 and ccrBm2, which shared 94.3% and 96.6% DNA identity with those of the SCCmec-like element of JCSC7096 but shared less than 52% DNA identity with the staphylococcal ccrAB and ccrC genes. Three distinct extrachromosomal circularized elements (the entire SCCmecKM45013, ΨSCCmecKM45013 lacking the ccr genes, and SCCKM45013 lacking mecB) flanked by one ISS copy, as well as the chromosomal regions remaining after excision, were detected. An unconventional circularized structure carrying the mecB gene complex was associated with two extensive direct repeat regions, which enclosed two open reading frames (ORFs) (ORF46 and ORF51) flanking the chromosomal mecB-carrying gene complex. This study revealed M. caseolyticus as a potential disease-associated bacterium in dogs and also unveiled an SCCmec element carrying mecB not associated with Tn6045 in the genus Macrococcus.

Gay Parenthood and the Revolution of the Modern Family: An Examination of the Unique Barriers Confronting Gay Adoptive Parents

Abstract: In recent decades, the structure of the American family has been revolutionized to incorporate families of diverse and unconventional compositions. Gay and lesbian couples have undoubtedly played a crucial role in this revolution by establishing families through the tool of adoption. Eleven adoptive parents from the state of Connecticut were interviewed to better conceptualize the unique barriers gay couples encounter in the process adoption. Both the scholarly research and the interview data illustrate that although gay couples face enormous legal barriers, the majority of their hardship comes through social interactions. As a result, the cultural myths and legal restrictions that create social hardships for gay adoptive parents forge a vicious and discriminatory cycle of marginalization that American legal history illustrates is best remedied through judicial intervention at the Supreme Court level. While judicial intervention, alone, cannot change the reality of gay parenthood, I argue that past judicial precedent illustrates that such change can serve as a tool of individual, political, and legal validation for the gay community for obtaining equal rights.
