Flattened Hierarchy Through Drama-Based Pedagogy: A Graduate Student Instructor and Two Undergraduates Partner on Classroom Research

ABSTRACT In this paper, the authors describe their journey from a teacher-student relationship to that of research partners and co-authors, thus providing a case study situated within the literature on students as partners. The instructor's use of drama-based pedagogy organically facilitated this journey both by flattening the hierarchy between teacher and students, and by being the subject under study. As a research group, the authors designed and collaborated on a scholarship of teaching and learning (SoTL) project. They analyzed existing classroom data to study the effects of drama-based pedagogy on their classroom environment and presented findings at conferences and through publication. This collaboration between a graduate student instructor and her undergraduate learners benefited all parties from both research and professionalization perspectives, which mirrors positive outcomes in the students as partners literature. The partnership can thus serve as a model for similar partnerships with minimal institutional infrastructure. Graduate students become research mentors and gain greater access to their students' classroom experiences, while undergraduate students explore the next step of an academic career track by conducting and disseminating original research as equal partners. The authors highlight reciprocity in their collaboration and call on institutions to facilitate this kind of partnership with funding and institutional support.
Tiny graviton matrix theory/SYM correspondence: Analysis of BPS states

In this paper we continue analysis of the Matrix theory describing the DLCQ of type IIB string theory on AdS{sub 5}xS{sup 5} (and/or the plane-wave) background, i.e. the tiny graviton matrix theory (TGMT) [M. M. Sheikh-Jabbari, J. High Energy Phys. 09 (2004) 017. ]. We study and classify 1/2, 1/4, and 1/8 BPS solutions of the TGMT which are generically of the form of rotating three-brane giants. These are branes whose shape are deformed three-spheres and hyperboloids. In lack of a classification of such ten-dimensional type IIb supergravity configurations, we focus on the dual N=4 four-dimensional 1/2, 1/4, and one 1/8 BPS operators and show that they are in one-to-one correspondence with the states of the same set of quantum numbers in TGMT. This provides further evidence in support of the matrix theory.
The effects of real and financial integration on output fluctuations in East Asia

The paper analyzes how regional financial and trade integration have affected output fluctuations in East Asia. It also controls for possible effects of specialization patterns and exchange rate policies. The findings hint at a convergent direct effect of trade and FDI integration on output fluctuations. Real and financial integration also have sizable indirect effects on output fluctuations through their impact on each other, as well as on specialization. The overall effects are positive in both cases. Moreover, trade and FDI integration reduce specialization patterns, and exchange rate volatility has a very strong negative effect on trade for East Asian economies.
Essays on Firms and Human Behavior

OF THE DISSERTATION Essays on Firms and Human Behavior by Nicolas Aguelakakis Doctor of Philosophy in Economics Washington University in St. Louis, 2015 Professor Brian Wade Rogers, Chair This dissertation studies three di erent topics related to the economic science. In the rst chapter, it is shown that collaborations between rms can have more harmful consequences on prices than a consolidation between them. We analyze a symmetric joint venture in which rms facing external competition collaborate in input production. Under standard regularity conditions, the collaboration leads to higher pro ts than a horizontal merger, whereas the e ect on prices and quantities depends on the form of downstream competition. When rms compete in prices, downstream prices for all rms are higher following a symmetric joint venture than following a merger. The reverse result may obtain under quantity competition. In light of our results regarding pro ts, we provide reasons why rms might still wish to merge: imperfect information, cost synergies, and organizational asymmetries. On the second chapter, it is measured the impact on retail prices for a gas station if a bigbox store starts selling gasoline to consumers. To the concern of their smaller competitors Wal-Mart, big-box stores, and other high-volume, low-price retailers have entered many retail industries globally in recent decades. In particular, big-box stores have increased in presence and market share in the U.S. retail gasoline industry. We examine the price impact of these "hypermarts" on traditional gasoline retailers and nd it to be economically large. The presence of a hypermart reduces a mean retailer's pro t by over one-half. This impact
Personality and adjustment in South African higher education accounting studies

This study seeks to investigate the contribution of individual personality differences to diverse aspects of accounting student adjustment to university in the context of a South African university. In a context in which many have but one opportunity to access higher education, knowledge of specific personality-related vulnerabilities to adjustment is considered. Multiple linear regression analysis was applied to 939 questionnaire responses of first-year accountancy students. Findings indicate that conscientiousness may offer an adjustment advantage across almost all adjustment dimensions, and neuroticism might represent a specific vulnerability. Findings may have implications for university contexts globally which share similarities with the South African university context of increasing diversity.
The requirement of yeast replication origins for pre-replication complex proteins is modulated by transcription

The mini-chromosome maintenance proteins Mcm2–7 are essential for DNA replication. They are loaded onto replication origins during G1 phase of the cell cycle to form a pre-replication complex (pre-RC) that licenses each origin for subsequent initiation. We have investigated the DNA elements that determine the dependence of yeast replication origins on Mcm2–7 activity, i.e. the sensitivity of an origin to mcm mutations. Using chimaeric constructs from mcm sensitive and mcm insensitive origins, we have identified two main elements affecting the requirement for Mcm2–7 function. First, transcription into an origin increases its dependence on Mcm2–7 function, revealing a conflict between pre-RC assembly and transcription. Second, sequence elements within the minimal origin influence its mcm sensitivity. Replication origins show similar differences in sensitivity to mutations in other pre-RC proteins (such as Origin Recognition Complex and Cdc6), but not to mutations in initiation and elongation factors, demonstrating that the mcm sensitivity of an origin is determined by its ability to establish a pre-RC. We propose that there is a hierarchy of replication origins with respect to the range of pre-RC protein concentrations under which they will function. This hierarchy is both ‘hard-wired’ by the minimal origin sequences and ‘soft-wired’ by local transcriptional context.
Exploring the uneven effects of economic recession and austerity on lone mothers : a critical realist intersectional approach

Latest studies have not only acknowledged the gendered and classed ‘nature’ of the latest economic recession and government austerity, but also their uneven impacts across the UK population. Accordingly, lone mothers have been identified as one of the groups most adversely affected. It is essential then to extend the research base on lone mothers as they already experience multiple disadvantages as a result of being the sole earner/carer of their family unit. It is also important to explore the uneven effects of these wider socioeconomic processes using an encompassing theoretical framework which grapples with how the intersections of multiple social categories can be examined simultaneously to shed light on differential outcomes. Thus, this thesis explores lone mothers using an overarching critical realist intersectional framework to acknowledge their locations in multiple structural inequalities, and also their agential strategies when facing wider socioeconomic pressures. Using a mixed-methods design, three sub-groups of lone mothers differentiated by distinctive multiple categories of social division are identified. Based on these three sub-groups, paid employment, welfare entitlement and agential responses to recession and austerity are examined. The findings drawn by this exploration elucidate the uneven effects of the institutionalisation of neoliberalism in the economy, the labour market and the welfare state. Those differentiated effects are explained not only by experiencing lone motherhood, but also by their particular multiple intersectional positioning. Thus, this thesis offers a valuable and original contribution to knowledge in the following three aspects: in extending the current research base on the differential impact of the economic recession and austerity on lone mothers, in intersectional theory by designing and applying an innovative critical realist intersectional framework and in mixed-methods research by employing an original longitudinal exploratory mixed-methods design.
The role of cytokines in hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is a frequent malignancy worldwide with a high rate of metastasis. The hepatitis B and C viruses are considered major etiological factors associated with the development of HCC, particularly as a result of their induction of chronic inflammation. There is increasing evidence that the inflammatory process is inherently associated with many different cancer types, including HCC. Specifically, this review aims to cover evidence for the potential roles of cytokines, an important component of the immune system, in promoting HCC carcinogenesis and progression. A global summary of cytokine levels, functions, polymorphisms, and therapies with regard to HCC is presented. In particular, the role of proinflammatory Th1 and anti‐inflammatory Th2 cytokine imbalances in the microenvironment of HCC patients with metastasis and the possible clinical significance of these findings are addressed. Overall, multiple studies, spanning many decades, have begun to elucidate the important role of cytokines in HCC.
STRINGS, PATHS AND STANDARD TABLEAUX

For the vacuum sectors of regime-III ABF models, we observe that two sets of combinatorial objects: the strings which parametrize the row-to-row transfer matrix eigenvectors, and the paths which parametrize the corner transfer matrix eigenvectors, can both be expressed in terms of the same set of standard tableaux. Furthermore, the momenta of the strings, the energies of the paths, and the charges of the tableaux are such that there is a weight-preserving bijection between the two sets of eigenvectors, wherein the tableaux play an interpolating role. This bijection is so natural, that we conjecture that it exists in general.
Personal Differences among Brazilian Adolescents with Distinct Levels of Engagement in Delinquency

Many adolescents manifest delinquent behavior, but only a few are responsible for most of the offenses and the serious crimes. To know the differences in the criminal engagement and in the personal variables related to the more persistent/severe antisocial behavior is important to adjust the Juvenile Justice Systems to the adolescents needs. In the Brazilian Justice System, this is not considered. Although the law indicates the importance of personalizing legal and social responses to each juvenile offender, the treatment is essentially undifferentiated. Therefore, the purpose of this study was to identify and describe personal variables that discriminate subgroups of Brazilian adolescents with different levels of criminal engagement. A total of 193 male adolescents (133 recruited in schools and 60 institutionalized) answered a Self-Report Delinquency Questionnaire, which included scales of psychosocial constructs. Five groups were found by the Ward and K-means clustering methods. The adolescents were compared on variables such as personal traits. Those groups with major criminal engagement had higher levels of impulsivity (I·Â² = 0.08; p = 0.002), higher antisocial values (I·Â² = 0.08; p = 0.003), and higher prevalence of alcohol (XÂ² = 103.75; p < 0.001) and marijuana use (XÂ² =257.61; p < 0.001). This finding confirms the specialized literature, denoting how important it is to identify and understand the differences in the criminal engagement of adolescents.
Full-Thickness Retinochoroidal Incision in the Management of Central Retinal Vein Occlusion

Purpose. To evaluate the clinical outcomes in patients with central retinal vein occlusion (CRVO) treated with full-thickness retinochoroidal incisions and to compare whether there is difference in treatment response in ischemic and nonischemic CRVO. Methods. Retrospective study of patients of CRVO receiving full-thickness retinochoroidal incisions in Changhua Christian Hospital. Fluorescein angiography (FA), slit-lamp biomicroscopy, indirect funduscopy, best corrected visual acuity, and central macular thickness (CMT) measured by optical coherence tomography were performed pre- and postoperatively. Patients were divided into an ischemic and nonischemic group according to the findings of FA. Patients were followed up for at least 1 year. Results. Twenty-eight eyes (14 ischemic and 14 nonischemic CRVO) were included. Functional retinochoroidal venous anastomosis (RCVA) was achieved in 48 of the 65 retinochoroidal incisions (73.8%). Central macular thickness (CMT) and retinal hemorrhage decreased significantly after the surgery. Significant visual gain was observed postoperatively in the nonischemic group, but not in the ischemic group. Postoperative complications included vitreous hemorrhage (17.8%), neovascular glaucoma (7.1%), and preretinal fibrovasular membrane (10.7%), all of which were in the ischemic group. Conclusions. RCVA formation induced by retinochoroidal incisions could improve venous flow, and decrease CMT and retinal hemorrhage. However, only eyes with nonischemic CRVO showed visual improvement.
Relationship between Household Air Pollution from Biomass Smoke Exposure, and Pulmonary Dysfunction, Oxidant-Antioxidant Imbalance and Systemic Inflammation in Rural Women and Children in Nigeria

Background: Exposure to particulate matter from burning biomass fuels is believed to affect oxidant-antioxidant balance and to induce oxidative stress. Methods: Fifty-nine mother-child pairs from 59 households that used firewood exclusively for cooking in three rural communities in southwest Nigeria underwent blood test for albumin, pre-albumin, retinol-binding protein (RBP), superoxide dismutase (SOD), vitamins C, vitamin E, malondialdehyde (MDA) and C-reactive protein (CRP). Spirometry was performed and indoor levels of PM2.5 were determined. Results: Mean age (± SD; years) of mothers and children was 43.0±11.7 and 13.6±3.2, respectively. The median indoor PM2.5 level was 1575.1 µg/m3 (IQR 943.6–2847.0, p<0.001), which is substantially higher than the World Health Organization (WHO) standard of 25 µg/m3. The mean levels of pre-albumin (0.21±0.14 g/dL) and RBP (0.03±0.03 g/dL) in women were significantly lower than their respective normal ranges (1-3 g/dL and 0.2-0.6 g/dL, respectively, p<0.05). Similarly, the mean levels of pre-albumin (0.19±0.13 g/dL) and RBP (0.01±0.01 g/dL) in children were significantly lower than the respective normal ranges (1-3 g/dL and 0.2-0.6 g/dL, respectively, p<0.05). Mean serum concentrations of MDA in children (5.44±1.88 µmol/L) was positively correlated to serum concentrations of CRP (r=0.3, p=0.04) and negatively correlated to lung function (FEV1/FVC) in both mothers and children (both r=-0.3, p<0.05). Also, regression analysis indicates that CRP and SOD are associated with lung function impairment in mothers (-2.55±1.08, p<0.05) and children (-5.96±3.05, p=0.05) respectively. Conclusion: Exposure to HAP from biomass fuel is associated with pulmonary dysfunction, reduced antioxidant defense and inflammation of the airways. Further studies are needed to better define causal relationships and the mechanisms involved.
Star formation in accretion discs: from the Galactic center to active galactic nuclei

Context. Keplerian accretion discs around massive black holes (MBHs) are gravitationally unstable beyond a few hundredths of a parsec, and they should collapse to form stars. It has indeed been shown recently that an accretion/star formation episode took place a few million years ago in the Galactic center (GC). This raises the question of how the disc can survive in AGN and quasars and continue to transport matter towards the black hole. Aims. We study the accretion/star formation process in quasars and AGN with one aim in mind: to show that a spectrum similar to the observed one can be produced by the disc. Methods. We compute models of stationary accretion discs that are either continuous or clumpy. Continuous discs must be maintained in a state of marginal stability so that the rate of star formation remains modest and the disc is not immediately destroyed. The disc then requires additional heating and additional transport of angular momentum. In clumpy discs, the momentum transport is provided by cloud interactions. Results. Non-viscous heating can be provided by stellar illumination, but in the case of continuous discs, even momentum transport by supernovae is insufficient for sustaining a marginal state, except at the very periphery of the disc. In clumpy discs it is possible to account for the required accretion rate through interactions between clouds, but this model is unsatisfactory because its parameters are tightly constrained without any physical justification. Conclusions. Finally one must appeal to non-stationary discs with intermittent accretion episodes like those that occurred in the GC, but such a model is probably not applicable either to luminous high redshift quasars or to radio-loud quasars.
The differential role of ethnicity on women's workplace experiences

by WENDY RENEÉ REYNOLDS-DOBBS (Under the Direction of KECIA M. THOMAS) ABSTRACT As more and more women enter leadership positions in the workplace, it is imperative to study and understand the unique career experiences and obstacles that hinder their professional development. Although most women deal with similar barriers to success in organizations, women of color tend to deal with additional hurdles in the workplace due to their double minority status. This study examined the relationships among ethnicity, organizational experiences, perceived discrimination, well-being, and organizational attachment for professional women. The results of the path analysis revealed that women of color have more negative organizational experiences, perceive more discrimination, and are less attached to their organization than White women. Furthermore, women who have more negative organizational experiences have more negative career outcomes and well-being issues. Implications for women’s career development research and supporting organizational practices are offered.
Disruption of the NF-H Gene Increases Axonal Microtubule Content and Velocity of Neurofilament Transport: Relief of Axonopathy Resulting from the Toxin β,β′-Iminodipropionitrile

To investigate the role of the neurofilament heavy (NF-H) subunit in neuronal function, we generated mice bearing a targeted disruption of the gene coding for the NF-H subunit. Surprisingly, the lack of NF-H subunits had little effect on axonal calibers and electron microscopy revealed no significant changes in the number and packing density of neurofilaments made up of only the neurofilament light (NF-L) and neurofilament medium (NF-M) subunits. However, our analysis of NF-H knockout mice revealed an ∼2.4-fold increase of microtubule density in their large ventral root axons. This finding was further corroborated by a corresponding increase in the ratio of assembled tubulin to NF-L protein in insoluble cytoskeletal preparations from the sciatic nerve. Axonal transport studies carried out by the injection of [35S]methionine into spinal cord revealed an increased transport velocity of newly synthesized NF-L and NF-M proteins in motor axons of NF-H knockout mice. When treated with β,β′-iminodipropionitrile (IDPN), a neurotoxin that segregates microtubules and retards neurofilament transport, mice heterozygous or homozygous for the NF-H null mutation did not develop neurofilamentous swellings in motor neurons, unlike normal mouse littermates. These results indicate that the NF-H subunit is a key mediator of IDPN-induced axonopathy.

The Nature of Shocks in Europe and in Germany

The plan for European Monetary Union (EMU) hangs in part on the incidence of aggregate demand and supply shocks in the participating countries. This paper addresses that question empirically using a bivariate VAR. Identification of the underlying orthogonal demand and supply shocks is achieved using only long-run restrictions. Data for sixteen European countries and eleven West German states (Lander) show that the correlation of shocks among the EU countries is much lower than within Germany. This implies that there remain questions about the advisability of EMU. Copyright 1997 by The London School of Economics and Political Science
