description: A field kinetic coupling with the Einstein tensor leads to a gravitationally enhanced friction during inflation, by which even steep potentials with theoretically natural model parameters can drive cosmic acceleration. In the presence of this non-minimal derivative coupling we place observational constraints on a number of representative inflationary models such as chaotic inflation, inflation with exponential potentials, natural inflation, and hybrid inflation. We show that most of the models can be made compatible with the current observational data mainly due to the suppressed tensor-to-scalar ratio.

description: Abstrak
Problems in improving teacher professionalism include teachers' low motivation to improve their abilities due to age, inability to use information and lack of enthusiasm for competition. Teachers feel more comfortable without having to bother following efforts to increase professional competence. Under these conditions, efforts are needed to improve teacher competency through the management Quality Control Circle (QCC). This research aims to obtain an overview and analysis of management QCC to improve the professional competence of MTsN teachers through a qualitative research approach using the case study method. To discuss research findings using quality assurance system management theory using the PDCA (Plan, Do, Check Act) cycle. Spencer's Competency Theory is a characteristic that underlies a person and is related to the effectiveness of an individual's work in their work. Data sources were obtained through observations, documents and interviews with Madrasah Principals, Deputy Madrasah Principals, Teachers and School Committees and Supervisors at MTsN 1 and MTsN 2 in Palangka Raya City. The results of this research found that QCC planning had been carried out by pursuing ideal planning principles but was not yet optimal. The implementation of QCC pays little attention to quality management aspects. QCC evaluation does not pay enough attention to the success of teachers' professional competency measures. QCC follow-up is still faced with obstacles to the consistency and cohesiveness of the QCC team.

description: The critical tum in language policy and planning has transformed it into a discipline that can bring the inequalities in social structures to light. In the field of language education, it can reveal how the policies and guidelines regulated at the macro­level impose their discourse on the micro-level and influence the perceptions and practices of their recipients. Ethnography of language policy has been used to explore the interplay and interaction between the macro and micro-level discourses and investigate the areas of inconsistency, ambiguity and contradiction. It is applied to inquire about the perceptions and experiences of policy recipients, to give voice to the underrepresented, and call for policy reform. While Alberta is serving a considerable number of ESL students, these students have been documented to be underachievers, both academically and socioculturally. This study explores the outcomes of the interpretation and implementation of ESL education polices by looking into the perceptions and practices of the agents in a charter school in Alberta. The findings of this study suggest that the educational objectives of ESL policies cannot be fully achieved unless the actual experiences of agents at the micro-level are taken into consideration. The study indicates that there are barriers hindering the academic and sociocultural integration of ESL students into the mainstream education system. It suggests that the picture illustrating ESL students as underachievers needs to be replaced by acknowledging these students' academic and sociocultural potential through policy reform that empowers the education system to help them reach their full potential.
Fast radiative transfer of dust reprocessing in semi-analytic models with artificial neural networks

description: A serious concern for semi-analytical galaxy formation models, aiming to simulate multi-wavelength surveys and to thoroughly explore the model parameter space, is the extremely time consuming numerical solution of the radiative transfer of stellar radiation through dusty media. To overcome this problem, we have implemented an artificial neural network algorithm in the radiative transfer code GRASIL, in order to significantly speed up the computation of the infrared SED. The ANN we have implemented is of general use, in that its input neurons are defined as those quantities effectively determining the shape of the IR SED. Therefore, the training of the ANN can be performed with any model and then applied to other models. We made a blind test to check the algorithm, by applying a net trained with a standard chemical evolution model (i.e. CHE_EVO) to a mock catalogue extracted from the SAM MORGANA, and compared galaxy counts and evolution of the luminosity functions in several near-IR to sub-mm bands, and also the spectral differences for a large subset of randomly extracted models. The ANN is able to excellently approximate the full computation, but with a gain in CPU time by $\sim 2$ orders of magnitude. It is only advisable that the training covers reasonably well the range of values of the input neurons in the application. Indeed in the sub-mm at high redshift, a tiny fraction of models with some sensible input neurons out of the range of the trained net cause wrong answer by the ANN. These are extreme starbursting models with high optical depths, favorably selected by sub-mm observations, and difficult to predict a priori.

On the Impossibility of Informationally Efficient Markets: Reply

name: Grossman, Sanford J.
Publisher: name: Columbia University
Year: 1982
Subjects: Economics

description: The article presents a reply to the comments of economist Richard Cothren on a paper related to efficient market theory written by the authors. According to the author Cothren's assertion that the authors incorrectly derived an informed trader's risky asset demand function is false. They permitted borrowing and short selling. For this reason there is no nonnegativity constraint on a trader's holdings of risky or risk-free assets. A trader's initial wealth is not the limit on the value of the risky assets that he can purchase. The trader can borrow, and in so doing finance a large purchase of risky assets. The goal of their paper was to show that when information is costly, a perfectly competitive equilibrium will not exist which completely transmits the informed traders' information to uninformed traders. It would have been trivial to prove that constraints on borrowing, or on short sales, prevent perfect arbitrage from occurring. They proved a more interesting result, which is that even in the absence of constraints on borrowing or short sales, markets cannot be fully arbitraged, when information about the arbitrage opportunity is costly.

An investigation into the concept of heat : a study of chemistry instructors’ alternate conceptions
Creators: name: Goodman, Donna-Leigh
Publisher: name: University of British Columbia
Year: 2011

description: Research has shown that chemistry students often possess alternate conceptions regarding the ‘heat’ concept. This is a problem because understanding heat in chemistry is pivotal to a meaningful comprehension of many other heat-related scientific concepts, such as temperature, kinetic energy, and work. Studies indicate that students frequently exit chemistry courses with inaccurate conceptualizations of heat. The implications for teaching are that whenever students’ reasoning about heat is faulty, then it becomes pedagogically important to examine, also, the chemistry instructors’ conceptualizations. As language is a powerful method of representation of knowledge and ideas in chemistry education, alternate conceptions may be directly transmitted through inaccurate articulation, such as misused metaphors and analogies. This investigation involves determining instructors’ various understandings of the meaning of the heat concept as taught in college preparation and first-year level chemistry classes. A sample consisting of currently practicing chemistry instructors from local colleges and universities completed a survey-questionnaire describing a lesson on how they teach the heat concept to their students by making an audio digital recording. To support this investigation the chemistry textbooks used by the instructors were linguistically analyzed for definitions and explanations of heat. Analytically, this study employs the qualitative methodology of grounded theory to inductively develop emergent theory from the data through a constant comparative process. Grounded theory allows movement from in-depth studies to more general accounts of wider context which offer testable predictions verifiable by traditional experimental and statistical means. The results of this study indicate that instructors do hold many alternate conceptions about heat and use them during instruction, of which several or more are discrepant with the accepted views of the scientific community. I argue that chemistry instructors need to identify and understand the use of these alternate conceptions, and find ways to counteract them through conceptual change-based pedagogy, before passing them on to students. I suggest instructors speak about heat as a process rather than as a substance to support development of the correct scientific meaning of heat. This inquiry also shows that chemistry textbooks contain incorrect language, and misconceptions, about the heat concept likely contributing to the problem.

description: Context. The circumstellar environment of evolved stars is generally rich in molecular gas and dust. Typically, the entire environment is either oxygen-rich or carbon-rich, depending on the evolution of the central star. Aims. In this paper we discuss three evolved disc sources with evidence of atypical emission lines in their infrared spectra. The stars were taken from a larger sample of post-AGB binaries for which we have Spitzer infrared spectra, characterised by the presence of a stable oxygen-rich circumbinary disc. Our previous studies have shown that the infrared spectra of post-AGB disc sources are dominated by silicate dust emission, often with an extremely high crystallinity fraction. However, the three sources described here are selected because they show a peculiar molecular chemistry. Methods. Using Spitzer infrared spectroscopy, we study in detail the peculiar mineralogy of the three sample stars. Using the observed emission features, we identify the different observed dust, molecular and gas species. Results. The infrared spectra show emission features due to various oxygen-rich dust components, as well as CO2 gas. All three sources show the strong infrared bands generally ascribed to polycyclic aromatic hydrocarbons. Furthermore, two sample sources show C60 fullerene bands. Conclusions. Even though the majority of post-AGB disc sources are dominated by silicate dust in their circumstellar environment, we do find evidence that, for some sources at least, additional processing must occur to explain the presence of large carbonaceous molecules. There is evidence that some of these sources are still oxygen-rich, which makes the detection of these molecules even more surprising.

description: The goal of this thesis is to investigate how second language learners of German perceive language variation. A three-part linguistic experiment was carried out on twenty university students to determine their ability to discriminate dialects from the standard language, their understanding of dialects, and their attitudes towards dialects. I found that the discrimination ability of students is generally high, and that language proficiency predicted discrimination ability. Intelligibility was generally poor and was unaffected by language proficiency. Students generally found Low German dialects to be more pleasant than Central and Upper German dialects.

For cases (a) and (c), we also calculate the differential cross section to $\ell^+f^-V$, where $V=W,Z,γ$, and $\ell$ is a light fermion that may or not be the same as $f$. The form of the cross section depends on whether the DM is a Majorana fermion or a scalar but in both cases its form is independent of $V$.

description: In this article the authors present a general set of arguments applicable to both competitive and noncompetitive environments, to situations where all the terms of the contract are determined in an optimal way, as well as to situations where many of the terms are specified institutionally. Much of the formal analysis of this article focuses on showing how the landlord, by altering, say, the terms at which he makes loans available to his tenants, not only can induce the tenant to borrow more but, more importantly, can induce the tenant to work harder or to undertake projects which are more to the liking of the landlord. Section I of this article examines interlinked credit and tenancy contracts; section II examines interlinked marketing and tenancy contracts; section III points out the possible interlinking between labor contracts and consumption goods markets; and section IV presents the different equilibrium frameworks discussed in this article, that is, monopoly, monopsony, competition, and equilibria with surplus labor.

description: We present a spectrum of highly excited charmonium mesons up to around 4.5 GeV calculated using dynamical lattice QCD. Employing novel computational techniques and the variational method with a large basis of carefully constructed operators, we extract and reliably identify the continuum spin of an extensive set of excited states, states with exotic quantum numbers (0+-, 1-+, 2+-) and states with high spin. Calculations are performed on two lattice volumes with pion mass approximately 400 MeV and the mass determinations have high statistical precision even for excited states. We discuss the results in light of experimental observations, identify the lightest 'supermultiplet' of hybrid mesons and comment on the phenomenological implications of the spectrum of exotic mesons.

description: Butler (2009) in Frames of War asked about the frames through which we have come to understand grievable and precarious lives. She asked us to consider how our boundedness with others makes all of our lives precarious. In this dissertation, I consider how post-secondary teachers might frame the necessity of using materials that depict suffering and the effects on students from encountering such materials. There is an aporia in this topic; that using materials that depict suffering could both enrich and impede learning. The practice of depicting sufering others may be fraught with representational challenges and this topic sits within a discourse that remains unresolved and contentious. Recognizing this impasse, I thought that a hermeneutic approach was necessary. Interpretive inquiry provides a reflection of how a topic might present itself in the world. Therefore, I invited six post-secondary teachers from human service programs who use materials that depict suffering to dialogue about their practices; in addition, a post­secondary counsellor was also invited to join these conversations. The participants assisted in opening up the topic, and they described pedagogical experiences that garnered my attention. True to hermeneutic work, what is offered herein is not about the participants but rather the topic. These pages speak to the aporia of using traumatic materials in teaching, and include the complications related to teachers' ethical responsibilities. While I stopped short of providing an answer to the aporia of this topic, I offer an opportunity for post-secondary teachers to consider their own actions and their own responses to students who have suffered from encountering such materials. In essence, I throw open an opportunity to understand this teaching practice as a reflection of the self in relation to others through the work of Paul Ricoeur. I also offer questions that may open up a new understanding of the assumptions we take up easily when we are teaching, and how such assumptions impact the students in our care. It is my hope that opening up this topic for further discussions could bring about more informed and responsible teaching practices in the future.

description: We study experimentally and theoretically polarization-dependent luminescence from an ensemble of quantum-dot-like nanostructures with a very large in-plane shape anisotropy (quantum dashes). We show that the measured degree of linear polarization of the emitted light increases with the excitation power and changes with temperature in a non-trivial way, depending on the excitation conditions. Using an approximate model based on the k.p theory, we are able to relate this degree of polarization to the amount of light hole admixture in the exciton states which, in turn, depends on the symmetry of the envelope wave function. Agreement between the measured properties and theory is reached under assumption that the ground exciton state in a quantum dash is trapped in a confinement fluctuation within the structure and thus localized in a much smaller volume of much lower asymmetry than the entire nanostructure.

description: Most prosocial and antisocial behaviors affect ourselves and others simultaneously. To know whether to repeat behaviors that help or harm, we must learn from their outcomes. But the neurocomputational processes supporting such simultaneous learning remain poorly understood. In this pre-registered study, two independent samples learned to make choices that simultaneously affected themselves and another person. Detailed model comparison showed that people integrate self- and other-relevant information into a single cached value per choice, but update this value asymmetrically based on different types of prediction errors related to the target (e.g., self, other) and valence (e.g., positive, negative). People who acquire more prosocial patterns are more sensitive to information about how their choices affect others. However, those with higher levels of subclinical psychopathic traits are relatively insensitive to unexpected outcomes for others. Model-based neuroimaging revealed distinct brain regions tracking prediction errors guided by the asymmetric value update. These results demonstrate that the way people distinctly encode self- and other-relevant outcomes resulting from their behavior guides how desirable the same behavior will be in the future, regardless of whether it is mutually beneficial or costly, instrumentally harmful, or altruistic.

description: Recent advances in photo technology have led to the advent of inexpensive light emitting diodes (LEDs) which provide the opportunity to cut the operational cost of photochemical treatment significantly. LEDs offer several advantages over conver:,tional mercury lamps which include a . long life, efficient u_tilization of energy, approximately monochromatic light and can be operated in DC power making it operational at remote locations. A photochemical study to degrade organics photocatalytically using dye-coated TiO2, TiO2 nanofiber, tin doped TiO2, platinum loaded TiO2 and P25 TiO2 under both visible and UV light has been investigated. Both fluorescent mercury lamp and LEDs were used as light sources. Laboratory scale investigations on i) the applicability of visible LEDs (A =436 nm) in degrading 4-chlorophenol (4-CP) by employing a dye (coumarin-343)-sensitized catalyst; ii) preparation of different nanoscale catalysts and their competitiveness with commercial catalyst in degrading 4-CP; and iii) photocatalytic dechlorination of polychlorinated biphenyls (PCBs) have been conducted. Subsequently a bench scale UV LED (A=365 nm) based photoreactor has been designed, fabricated and tested. Degradation of 4-CP by using a dye-sensitized catalyst under visible LED irradiation led to the generation of hydroxylated intermediates including ring opening. Laboratory studies on the competitiveness of the photocatalytic activities of four different nanoscale catalysts, under UV light irradiation at 350 nm, and coumarin (C-343) coated TiO2 nanofibers at 436 nm light emitting diodes (LED) showed the promise of utilizing nano-scale catalysts in degrading 4-CP. Photocatalytic dechlorination of polychlorinated biphenyls (PCBs) using platinum loaded TiO2 (P25) in an alkaline 2-propanol medium was found to be successful. Bench scale batch experiments using a Rayonet photo-reactor under black lamp . . . irradiation (11,=350 nm) showed complete dechlorination in a deaerated environment. Enhanced photocatalytic efficiency was observed when platinum loaded P25 was used as catalyst, with the best result being obtained when aqueous potassium hexachloroplatinate was added into the reaction medium. Design of a novel bench-scale flow-through light emitting diode (LED) based photocatalytic reactor and testing of the same in degrading 4-CP, atrazine, methylene blue (MB) under different conditions (bubbling oxygen, adding hydrogen peroxide) showed promising results.

Adults with intellectual disabilities and the visual arts : "It's not art therapy!"
Creators: name: Lige, Sara
Publisher: name: University of British Columbia
Year: 2011

description: This thesis examines the emerging discourse concerning adults with intellectual disabilities and their agency as visual artists. People with intellectual or developmental disabilities are arguably the most marginalized members of our society and have historically suffered oppression. They have not experienced the same access to the arts as non-disabled people; artists with intellectual disabilities are typically situated within a therapeutic paradigm and excluded from institutional structures of contemporary art. This thesis raises issues of access and identity and problematizes the hegemonic structures and boundaries faced by artists with intellectual disabilities within the field of contemporary art. This interdisciplinary project evolves from a Disability Studies perspective and is heavily influenced by Emancipatory Methodology. A brief overview of Disability Theory is provided including a discussion concerning ‘cognitive ableism’. I propose a theoretical framework that supports artists with intellectual disabilities as legitimate artists. Issues of ‘Outsider Art’ and art therapy are addressed. A key component is a discussion of Cool Arts and the exhibition “We Are Artists”, which I curated. The exhibition worked to counter stereotypes and included an exhibition catalogue written in Plain Language. The qualitative research component to this thesis examines the art-making practices of three participants. Data collection methods included participant observation, semi-structured interviews and video-elicitation; documentation of the art-making process served to validate and recognize the participants as legitimate artists. I argue that artists with intellectual disabilities are legitimate artists and must have the same access to the arts as non-disabled people. This research makes a significant contribution to an emerging discourse which, to date, has had little scholarly literature devoted to it. This thesis counters misconceptions, and brings attention to issues of access and the lack of research in this interdisciplinary field.
The historical light curve of the symbiotic star AG Draconis: intense, magnetically induced cyclic activity
Creators: name: Formiggini, Liliana

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We analyze an optical light curve of the symbiotic system AG Draconis covering the last 120 years of its history. During the first 32 years the system was in a quiescence state. Around the year 1922 the star's quiescence luminosity brightened by 0.29 mag. The last 82 years of the light curve (LC) are characterized by a series of outbursts of 1-2 magnitude in brightness and about 100 days in duration. The outbursts are distributed along the time axis in 6 clusters with a quasi-periodic cycle of some 5300 days. The time intervals among the outbursts themselves are integral numbers of the period 373.5 days. During quiescence states the LC oscillates with the binary period of the system of 550 d. The LC contains also a weak periodic signal with a period of 350 d, attributed to pulsations of the giant star. Another period of 1160 d is also present in the light curve, being the sidereal rotation period of the giant star. We suggest that the outbursts are events of intense mass transfer from the giant onto the hot component. These are modulated by an interplay between a solar-like magnetic dynamo cycle operating in the outer layers of the giant, and a tidal deformation of these layers that circulates the surface of the giant with the synodic diurnal period of 373.5 Earth days. AG Dra is the 5th symbiotic system with a light curve that reflects such an intense magnetic and magnetically modulated activity. (Abridged)

description: Research into music in the Third Reich has been relatively neglected by historians since WWII. This study investigates the impact of Third Reich policies on the Gesellschaft der Musilifreunde (GdMt), a major Viennese music Society, while the Society was under the Nazi Regime from 1938-1945. The GdMf case study evidence is measured against Primo Levi's "gray zone" theory of human behaviour in a totalitarian state. GdMf music programs flourished under Franz Schiltz, a professional musician and Nazi Party member. Under his GdMfleadership, the Nazis were not just perpetrators and the Viennese were not just victims. The study shows the response of the Viennese to the Nazi takeover of the Society can best be classified as collaboration, compromise and complicity. This case study also sheds light on the question of Austria as the first victim of Nazi aggression and how Austrians today are coming to terms with their Nazi past.
