description: The issue of college student retention remains a critical concern in higher education. Institutions have begun to address this issue through the development of academic enhancement programs. These programs are designed to increase student and prior research largely supports their efficacy. However, a paucity of research exists to demonstrate which mechanisms contribute to this positive change. This study, therefore, seeks to examine the role of cultural processes and therapeutic factors on the effectiveness of a group-based academic enhancement intervention. Consistent with prior research, this study is guided by the Psychosociocultural (PSC) model and the Multicultural Orientation (MCO) framework. Data for this study consisted of 70 students on academic probation enrolled in eight sections of an academic enhancement seminar. Latent Variable Structural Equation Modeling (LVSEM) was used to examine the direct and indirect effect of students’ perceptions of Group MCO and Instructor MCO on changes in their academic outcomes. Results indicated that Group MCO and Instructor MCO were not significantly related to changes in students’ GPAs. However, Instructor MCO was indirectly related to changes in students’ GPA vis-à-vis students’ perceptions of therapeutic factors. Findings demonstrate the importance of Instructor MCO in enhancing students’ experiences of therapeutic factors (e.g., hope and belonging) within academic enhancement groups and ultimately changes in their academic outcomes.

description: In this study, a simple protocol was developed to test the survival of a human rotavirus (HRV), rhinovirus type 14 (RV-14), and parainfluenzavirus type 3 (HPIV-3) as well as Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) on human hands. HPIV-3 lost nearly all of its infectivity within the first 60 minutes on the fingerpads. In contrast to this, nearly 16% of infectious RV-14 could be recovered even after 3 hours. The poor survival of HPIV-3 on human hands prompted us to investigate its survival on stainless steel disks (1 cm in diam.) under ambient conditions. The ability of the two respiratory viruses to survive well on non-porous inanimate surfaces indicates that, once contaminated, these surfaces may act as a potential virus source. To study the patterns of virus transfer, the following three experimental models were developed and tested: finger-to-finger, finger-to-disk and disk-to-finger. The results suggest that human hands and environmental surfaces, singly or in combination, have the potential to spread rotaviral infections, particularly in institutional settings. The comparatively rapid loss of HPIV-3 infectivity on hands may reduce their potential as vehicles for transmission. These results also suggest a role for environmental surfaces in the contamination of hands with respiratory viruses. We compared the efficiency of paper-, cloth- and an electric blow dryer in further reducing the level of infectious rotavirus and E. coli remaining on fingerpads washed with either 70% isopropanol, Savlon in water (1:200), an unmedicated liquid soap, or tap water alone. Irrespective of the hand-washing agent used, warm air drying produced the greatest and the cloth the smallest reduction in the numbers of both test organisms. These findings indicate the importance of the proper drying of washed hands, particularly when less effective hand-washing agents are used. The results of this study show that HRV, RV-14 and S. aureus can survive on human hands long enough to permit their spread through hands. In contrast to this, parainfluenzaviruses and E. coli appeared to be limited in their capacity to survive on hands. The differences found in the efficacy of commonly used hand-washing agents against HRV and the bacteria tested point to the importance of testing such products by proper in vivo protocols using representative viruses.

description: It has recently been established that mitochondria function as an interconnected reticulum that is maintained through dynamic fission and fusion events. The research performed throughout the course of this doctoral thesis has profound impacts on cell biology, impacting mitochondrial dynamics, programmed cell death, intracellular signaling, and peroxisome biology. Research into the protein mechanisms of mitochondrial fusion and fission is presented as two distinct research aims. The first objective of this thesis investigated the mechanisms and meaning of mitochondrial fusion; specifically the role of Mitofusin 2. It is presented as a manuscript which describes Mfn2 functioning as a signaling GTPase for mitochondrial fusion, rather then a mechanoenzyme, and that activated Mfn2 protects against both cytosolic and mitochondrial apoptosis as well as inhibits Bax activation. The second objective of this doctoral thesis was the investigation into the mechanisms and meaning of mitochondrial fission; specifically the role of a novel uncharacterized protein FLJ12875 (subsequently named MAPL). The identification of MAPL and a previously unrecognized pathway for mitochondrial vesiculation as a means to segregate selected cargo into distinct transport vesicles which traffic to the peroxisome is presented. MAPL is evolutionarily conserved from plants to bacteria and is an integral mitochondrial outer membrane protein. MAPL has two transmembrane domains and a carboy-terminal RING domain. Additionally it has an uncharacterized highly conserved middle domain positioned between the two membranes, the BAM domain (Beside A Membrane) MAPL overexpression results in a stimulation of Drp1-dependent mitochondrial fragmentation. Unexpectedly, it was found that in cells where mitochondrial fission was blocked, a pool of small (70-100 nm) vesicles enriched for MAPL and or TOM20 was observed. Convincing data are presented documenting that this pool of vesicles generates independently of the canonical mitochondrial fission pathway. This thesis describes the identification of a novel vesicular trafficking pathway for the cell. Both the signaling capabilities of Mfn2 and the identification of Mitochondrial Derived Vesicles (MDV's), provide a new platform for investigations of mitochondrial dynamics and opens up new avenues of research into mitochondrial mechanism and meaning.

description: Background and Aims Individualization of treatment with peginterferon alfa and ribavirin in patients with chronic hepatitis C showed benefit in controlled trials and was implemented in treatment guidelines to increase response rates and to reduce side effects and costs. However, it is unknown whether individualization was adopted in routine daily practice and whether it translated into improved outcomes. Methods From a large noninterventional cohort study, clinical and virologic response data of 10,262 HCV patients who received peginterferon alfa-2a and ribavirin between 2003-2007 and 2008-2011 were analyzed. To account for treatment individualization, a matched-pair analysis (2,997 matched pairs) was performed. Variation in treatment duration and dosing of ribavirin were analyzed as indicators for individualization. Results Sustained virological response (SVR) rates were similar between 2003-2007 and 2008-2011 (62.0% vs. 63.7%). Patients with comorbidities were more abundant in the later period, (44.3% vs. 57.1%). The subsequent matched- pair analysis demonstrated higher SVR rates in the 2008-2011 period (64.3%) than in the 2003-2007 period (61.2%, p=0.008). More patients received abbreviated or extended treatment regimens in the later than the earlier period as an indicator of treatment individualization. To the same end, ribavirin doses were higher in the later period (12.6 versus 11.6 mg/kg/day). Factors independently associated with SVR included HCV genotype, low baseline viral load, younger age, route of infection, absence of concomitant diseases, lower APRI score, normal gamma-GT, higher ribavirin doses, no substitution for drug abuse, treatment duration, and treatment in the 2008-2011 period. Conclusions Treatment individualization with peginterferon alfa and ribavirin was implemented in daily routine between 2003-2007 and 2008-2011, SVR rates improved in the same period. These findings may be most relevant in resource- limited settings.
Information manipulation and civil rebellion in autocratic regimes

description: Autocratic regimes are always under the threat of being overthrown by popular uprising. Apart from violent repression, autocratic regimes have also largely adopted strategies to manipulate information in order to deter civil rebellion. These strategies include ideology indoctrination, censorship, government propaganda, and more. Despite autocratic regimes’ multiple efforts, it is unclear whether these efforts are effective, especially in the age when information technologies greatly increase the free flow of information both internationally and domestically. This dissertation looks into autocratic regimes’ strategies of information manipulation with a focus on censorship and propaganda and attempts to answer the question of whether civil rebellion is deterred by these strategies. I argue that censorship and propaganda, as two measures of information manipulation in autocratic toolkits, may deter popular rebellion by either lowering citizens’ motives for social change or increasing the difficulty of mass mobilization. To test this argument, I use both cross-national time-series data from 2003 to 2018 on anti-regime movements in autocracies and a case study of China. I further construct my own measurement of propaganda using text analysis methods in this research. I also test which mechanism is at work in the empirical analysis. Empirical evidence shows that media censorship, internet censorship, and propaganda all contribute to lower numbers of anti-regime movements in autocratic regimes, although the mechanism varies. Further, I use the Hong Kong 2019 protest to illustrate how an autocracy may manipulation information, promote its own political rhetoric, and compete with Western media’s storytelling and narratives.
The key to dealing with P2P infringements: regulation, partnerships and education

description: In iiNet, the High Court held that current Australian copyright law is powerless to prevent large-scale peer-to-peer (P2P) infringements. A similar conclusion was previously reached by the Irish High Court in the UPC decision. This article compares and contrasts the two decisions, finding that the judges in both cases came to a number of similar conclusions. The article also explains how dealing with large-scale P2P infringements requires a combination of appropriate regulation, partnerships between the telecommunications and content industries and education. It concludes that, as in Ireland, legislative reform is needed to deal with the problem of P2P file-sharing.

description: Chronic exposure to pesticides has been associated with numerous adverse health effects including cancer, cognitive impairment, and endocrine system disruption. Because of their occupations, pesticide applicators may be at higher risk of illness from pesticide exposure.
description: Due to their semi-volatile nature, pesticides can exist both as particles and gases (vapors) in the air. Many pesticides have been assigned an inhalable fraction and vapor (IFV) endnote by the American Conference of Governmental Industrial Hygienists (ACGIH), indicating a need to sample for both their particle and vapor phases. The National Institute for Occupational Safety and Health (NIOSH) and the Occupational Safety and Health Association (OSHA) methods recommend the OSHA Versatile Sampler (OVS) when sampling for both phases simultaneously (NIOHS Method 5600 & 5601; OSHA Method 62 & 63). Unlike the OVS, the IFV Pro (SKC Inc) was designed to be an inhalable sampler and has been identified in one study to have a higher mass collection efficiency than the OVS in a laboratory setting (Alex et al., 2021).
description: The aims of this study were to: 1) assess the particle and dual-phase relative efficiencies of the OVS and IFV Pro in a simulated and real-world pesticide spraying operation; and 2) perform an exposure assessment of pesticide applicators from three Iowa companies. It was hypothesized that the IFV Pro would sample higher particle and vapor mass concentrations than the OVS and that participating pesticide applicators would not be exposed to significant levels of pesticide. Under the conditions in which the two samplers were compared in this study, results indicate an insignificant difference in the particle-phase collection efficiencies between the OVS (M=5.80 mg/m3, SD=1.77) and IFV Pro (M=5.56 mg/m3, SD=1.55) (t=1.48, p=0.11). Descriptive statistics did not prove that the OVS and IFV Pro relative dual-phase sampling efficiencies were different under the same conditions. Six applicators in this study experienced low exposure to glyphosate, dicamba, and MCPA herbicides. Exposure monitoring results indicate that the subjects are not at an increased risk of pesticide-induced illness and disease. Further research should assess the influence of directional drafts and other environmental conditions on the OVS, IFV Pro, and pesticide applicator exposure. Additional efforts should also be made to standardize an analysis method for the IFV Pro.

description: Objective: To quantify delays during management of children with suspected meningitis. Design: Multicentre prospective cohort study Setting: Three UK tertiary paediatric centres; June 2011-June 2012 Patients: 388 children aged <16 years hospitalised with suspected meningitis or undergoing lumbar puncture (LP) during sepsis evaluation. Main outcome measures: Time of pre-hospital and in-hospital assessments, LP, antibiotic treatment and discharge; types of pre-hospital medical assessment and microbiological results. Data collected from hospital records and parental interview. Results: 220/388 (57%) children were seen by a medical professional pre- hospitalisation (143 by a GP). Median times from initial hospital assessment to LP and antibiotic administration were 4.8 hours and 3.1 hours respectively; 62% of children had their LP after antibiotic treatment. Median time to LP was shorter for children aged <3 months (3.0 hours) than those aged 3-23 months (6.2 hours, p<0.001) or age ≥2 years (20.3 hours, p<0.001). In meningitis of unknown cause, CSF PCR was performed for meningococcus in 7%, pneumococcus in 10% and enterovirus in 76%. When no pathogen was identified, hospital stay was longer if LP was performed after antibiotics (median 12.5 days vs. 5.0 days, p=0.037). Conclusions: Most children had LP after antibiotics were administered, reducing yield from CSF culture, and PCRs were under-used despite national recommendations. These deficiencies reduce the ability to exclude bacterial meningitis, increasing unnecessary hospital stay and antibiotic treatment.

description: Objective Youth with mental health problems often have difficulties engaging in education and employment. In Australia, youth mental health services have been widely established with a key aim of improving role functioning; however, there is little knowledge of those who are not engaged in employment, education or training (NEET) and the factors which may influence this. This study aimed to examine NEET status and its correlates in a sample of such youth.Design Cross-sectional data from a longitudinal cohort study.Setting Between January 2011 and August 2012, young people presenting to one of the four primary mental health centres in Sydney or Melbourne were invited to participate.Participants Young adults (N=696) aged between 15 and 25 years (M=19.0, SD=2.8), 68% female, 58% (n=404) attended headspace in Sydney.Measures Individuals 'Not in any type of Education, Employment or Training' in the past month were categorised as NEET. Demographic, psychological and clinical factors alongside disability and functioning were assessed using clinical interview and self-report.Results A total of 19% (n=130/696) were NEET. NEETs were more likely to be male, older, have a history of criminal charges, risky cannabis use, higher level of depression, poorer social functioning, greater disability and economic hardship, and a more advanced stage of mental illness than those engaged in education, training or work. Demographics such as postsecondary education, immigrant background and indigenous background, were not significantly associated with NEET status in this sample.Conclusions One in five young people seeking help for mental health problems were not in any form of education, employment and training. The commonly observed risk factors did not appear to influence this association, instead, behavioural factors such as criminal offending and cannabis use appeared to require targeted intervention.

description: Previous work has identified the positive effects of the acute administration of a multivitamin-guarana; preparation during an effortful executive/working memory task. Here, we aimed to differentiate the effects of multivitamins with and without guarana and to examine the neural substrates of such effects using functional magnetic resonance imaging (fMRI). Following a double-blind, placebo-controlled, randomised, balanced crossover design, 20 participants (mean age 29 ± 5.54 years) consumed multivitamin preparations with or without guarana (Berocca® Performance and Boost, respectively) and a placebo. Thirty minutes post-treatment, they underwent neurocognitive assessment, consisting of a 10 min Cognitive Demand Battery, with mood ratings taken immediately before and after the battery. Five additional participants underwent post-treatment fMRI scanning during Rapid Visual Information Processing and Inspection Time activation tasks. The multivitamin with guarana treatment was associated with significantly enhanced Serial Threes performance and self-rated contentment. fMRI revealed that both multivitamin treatments increased activation in areas associated with working memory and attentional processing, with the effect being greater in the multivitamin with guarana condition. These data confirm the acute benefits of multivitamins with guarana on mood and cognitive performance. Furthermore, they demonstrate for the first time increased brain activation from multivitamin preparations both with and without guarana, as measured using fMRI.
A logic based approach to use case based requirement verification and domain model improvement

description: In software systems, a significant number of software errors and disasters can be traced to late detection of requirements errors. Hence, it is crucial to concentrate on early design phases to verify the primary design against user requirements. In this thesis, two model based verification methods are proposed for performing early design verification and validation. The first approach is a predicate based verification method termed 'Predicate based Sequential Verification (PSV)' which checks the domain model against semi-formal Natural Language (NL) based Use Cases. The PSV module reports requirement violations and model inconsistencies and suggests improvements to the domain model. A proof based strategy termed 'Scenario Sequential Verification (SSV) Strategy' is also discussed as an alternative method for proving domain model requirements which relies on Program Transformation method using Hoare logic. The second verification approach called 'Semi-Automated Validation (SAV)' verifies the formal design model (state chart) against Semiformal NL based Use Case requirements.

description: In the development of the Next Generation Science Standards (NGSS) there was a purposeful effort to not only include but prioritize science and engineering practices as part of the standards. Including the science and engineering practices in science curriculum and instruction is thought to help students understand how scientific knowledge develops and embed this knowledge in their worldview (3 Dimension 1: Scientific and Engineering Practices, 2012). Epistemic cognition, the concept of how one views knowledge and what beliefs they hold about knowledge, has been found to have significant influences on learning and academic success (Cano, 2005; Greene et al., 2018; Schommer, 1990).
description: This study utilized a self-report survey and presents the results of mixed-methods both quantitative and qualitative analysis to identify and bring saliency to correlational relationships between recent U.S. high school graduates’ self-perceptions in their ability to perform the eight NGSS science practices and two dimensions of epistemic cognition (source and structure of knowledge) and between the dimensions across domain specificity. Undergraduate college students were recruited to complete a scenario-based survey intended to elicit both general and science-specific domain epistemic beliefs as well as rank their self-perception in their ability to perform the eight NGSS science and engineering practices (SEP).
description: Findings from this study indicate that these students’ self-perceptions in performing the SEP were correlated to a number of source and structure beliefs both in science-specific knowledge and knowledge generally or as an unspecified concept. Participants use multiple sources and justificatory standards when encountering science knowledge contexts. Engaging in the SEP may help students to develop sophisticated conceptualizations of science knowledge and components of both science-specific and general epistemic cognition.
Suppression of tumorigenicity of the PA-1 human teratocarcinoma cell line.

description: Teratocarcinomas are tumors that develop spontaneously in the gonads, and usually contain a rapidly dividing undifferentiated stem-cell population. I have used microcell fusion to introduce individually tagged human chromosomes into the PA-1 human teratocarcinoma cell line. Introduction of human chromosome 4 caused a change of cell morphology in culture and suppressed PA-1 tumorigenicity in nude mice, while addition of portions of either chromosome 7 or 12 had no effect on the cell phenotype. The PA-1 cell line regained its tumorigenicity when the tagged chromosome 4 was lost under negative selection. Tumors were noted in the test period after two out of twelve injections of PA-1 harbouring an additional copy of chromosome 4. One tumor derived cell line had lost the complete tagged chromosome while the other had lost portions of the tagged chromosome (4p11-15.3 and q31.1). I concluded that there is a putative tumor suppressor gene on human chromosome 4 whose expression interferes with the tumorigenicity of PA-1 cells, and that this gene maps to the portion of chromosome 4 lost from the tumor-derived cell line. Differential display of mRNAs from PA-1-derived cell lines revealed that at least two genes, the immunoglobulin heavy chain binding protein (BiP gene) and a novel transcript, are over-expressed as a result of the introduction of chromosome 4 into PA-1. Coincident with the loss of tumorigenicity after introduction of chromosome 4, was an increase in the retinoic acid-induced differentiation of the cell line. Retinoic acid is a potent morphogen and has been implicated in development and differentiation in mammalian systems. Not only did the addition of the tagged chromosome 4 to PA-1 cause an increase in differentiation potential, it also caused an increase in the induction of both retinoic acid receptor-$\alpha$ and HOX1F gene expression. This implies that the increase in retinoid acid-induced differentiation in PA-1-derived cells occurs through a pathway involving retinoic acid receptor-$\alpha .$ Thus, the gene(s) mapping to 4p1.1-15.3 or q31.1 is not only responsible for the suppression of tumorigenicity of PA-1, but it also increases the differentiation potential of the cells.

description: Cette recherche a eu un objectif bien precis: construire les principes d'interpretation qui guident la lecture kantienne de la Bible. Cela a ete fait a partir d'une analyse de toute l'oeuvre de Kant touchant ce sujet. La these reconstruit trois contextes ou la hermeneutica sacra de Kant est nee: d'abord, un contexte d'epoque determine par les pensees de Kant sur la Aufklarung ainsi que par le pietisme. Ensuite, il existe dans la configuration de la Bibelauslegung de Kant un contexte de controverse. Kant fait face a plusieurs traditions hermeneutiques dont la souche est parfois historique, mystique, grammaticale, religieuse ou dogmatique. Dans ce sens, le philosophe de Konigsberg entre en polemique avec certains de ses contemporains, tels que Johann David Michaelis, Johann Kaspar Lavater, Manuel Swedenborg, Johann Georg Rosenmuller et Johann Gottfried Eichhorn. Il se montre par ailleurs que Kant critique aussi la doctrine interpretative de Luther pour la Bible ainsi que la position de la metaphysique dogmatique d'un Wolff et d'un Baumgarten par rapport au Livre des livres. En dernier lieu, il est question de la philosophie critique elle-meme d'ou le philosophe puise le contenu des differents principes de son exegese scripturaire. Dans les principes interpretatifs, des acquis venant de sa philosophie pratique, de sa philosophie theorique, de son esthetique et sa theorie de la histoire ont leur place essentielle. La recherche a construit six principes kantienns d'interpretation biblique: le principe de pertinence morale, le principe d'immanence, le principe de anhistoricisme, le principe d'antilitteralite, le principe de symbolisation et le principe d'autonomie. Chacun d'eux est illustre par des textes tires de l'oeuvre de Kant, sans oublier une mise a jour de son arriere-plan historique. Finalement, tous ces principes sont mis a preuve dans l'etude approndie de deux questions d'une importance capitale pour les theories interpretatives des Ecritures Saintes, c'est-a-dire la revelation scripturaire et la doctrine kantienne sur la justification. Une introduction, des conclusions et une complete bibliographie appartiennent de meme a l'ensemble de cette these doctorale.

description: The aurora (northern/southern lights) are a majestic display of light that illuminates the night sky at high latitudes in the northern and southern hemispheres. These lights come in several different varieties. Discrete and substorm aurora are the brightest and most photogenic type, but in this thesis we focus on the dimmer, but just as important, diffuse aurora. More specifically, we look at subsets of diffuse aurora that are also dynamic. A majority of this work is devoted to pulsating aurora, which appear as an uncoordinatedsymphony of dim auroral patches that blink on and off across wide portions of the sky. Pulsating aurora plays an important role in energy transfer between the magnetosphere and the upper atmosphere. This energy transfer can have significant impacts on the atmosphere, such as ozone depletion. Using electron density measurements from the Poker Flat Incoherent Scatter Radar, we were able to statistically quantify the energy flux of electrons responsible for pulsating aurora. We found a significant contribution from > 30 keV electrons, which increases in close temporal proximity to a substorm and for periods of high AE index. We also found that following a substorm, the energy flux from > 30 keV electrons decays with an e-folding time of 0.95 hr. Using wave measurements from the Van Allen Probes, we were able to connect this timescale to a similar e-folding time of 1.18 hr for lower-band chorus waves following a substorm. Combined, these results support the hypothesis that pulsating aurora represents a significant loss of energetic electrons from the outer radiation belt to the atmosphere. It also supports the hypothesis that pulsating aurora are the result of Doppler-shifted cyclotron resonance between energetic substorm electrons and lower-band chorus waves. However, much regarding diffuse and dynamic aurora is still unknown. This is evident in the diffuse auroral eraser, a new phenomenon that we characterize as a rapid brightening and then dimming of a diffuse arc superimposed on a background diffuse aurora. Upon dimming, the background aurora get erased and takes approximately 20 seconds to return to normal. We believe this feature may shed light on how different magnetospheric waves could influence each other. However, we need more observations to solve this puzzle and hope our results will inspire future studies into diffuse and dynamic aurora.

description: After three judgments between 2010-2, Roadshow has provided much needed clarity on what Internet Service Providers (ISPs) should - or should not - do when informed of alleged infringing activity by their customers. The judgments have also made useful suggestions on what an industry code for ISPs would look like. What is missing is a clearer understanding of the third parties in these debates - the public - the users. How do they use the Internet? What do they know of copyright? And if a code for ISPs is developed, how should it protect public rights to fair access to Internet content?
Le conflit des herméneutiques : Gadamer et Ricoeur en débat.

description: Cette thèse propose de faire la lumière sur le débat latent qui sévit entre les projets herméneutiques de Hans-Georg Gadamer et Paul Ricoeur. Elle est divisée en quatre chapitres. Nous commençons par camper les enjeux du débat en confrontant leurs conceptions de l'herméneutique, afin de soulever le problème de l'unité du champ de l'herméneutique contemporaine. Notre propos met ici en relief les traditions philosophiques dont sont issues les conceptions de chacun. Ainsi, nous faisons valoir que l'herméneutique de la facticité de Heidegger est à la source du paradigme dialogique que développe l'herméneutique ontologique de Gadamer. Quant à Ricoeur, nous montrons que le paradigme textuel de son herméneutique méthodologique lui vient surtout de la pratique de l'interprétation en théologie protestante. Le second chapitre s'intéresse au rôle déterminant qu'a eu Hegel pour le problème herméneutique de la conscience historique. Nous faisons valoir que Gadamer "intériorise" la dialectique hégélienne, tandis que Ricoeur y recourt un peu comme à une méthode pour résoudre les conflits d'interprétation. Mais nous montrons que tous les deux renoncent à l'hégélianisme, au nom d'une herméneutique de la conscience historique. C'est ici que s'amorce la position commune à leurs herméneutiques. Le troisième chapitre se penche sur la position de Gadamer et Ricoeur face à l'héritage diltheyien de l'herméneutique. Nous montrons comment Gadamer a élaboré son herméneutique philosophique en critiquant l'historicisme de Dilthey, alors que ce dernier a eu de toute évidence une plus grande influence sur celle de Ricoeur, qui considère que la thèse diltheyienne sur la fixation de la vie dans l'écriture a été fructueuse pour penser l'objectivité propre aux sciences humaines. Enfin, le quatrième chapitre montre comment leurs herméneutiques s'enracinent dans la philosophie pratique et relèvent le défi posé par l'altérité. La comparaison de leur interprétation de la doctrine aristotélicienne de la phronesis nous conduit alors au point de rencontre culminant des deux projets herméneutiques: la similitude entre la catégorie ontologique de l'être-en-dialogue chez Gadamer et la théorie de l'identité narrative chez Ricoeur est à notre avis décisive pour l'unité du champ de l'herméneutique contemporaine.

description: This project assembles a subset of 20th century LGBT-identified authors – Christopher Isherwood, John Rechy, Audre Lorde, Harvey Fierstein, and Tony Kushner – and examines the influence of media technologies like the telephone, gramophone, radio, and television on the metaphors, logics, and forms of their literature. Queer engagement with the media emerges in these texts as an oppositional practice, as a way for queer subjects to articulate and play with their identities, to pursue sexual pleasure, and to imagine a better world. Each chapter advances a media materialist approach to literary analysis that draws on insights from the field of media archaeology, which seeks to uncover the aesthetic, cultural, and political resonances of the media. Through their detailed representations of media technologies and their related networks and procedures, these authors stress the ecological, bodily, and material consequences that undergird the production and use of a given medium – often to the detriment of marginalized queer populations the world over – at the same time as they gesture toward the liberatory possibilities of certain mediums.
description: Furthermore, in their dual role as cultural producer and archivist, these authors envision literature as a means to store and transmit their visions of social transformation and queer collectivity into the future. Their texts are best understood as dynamic media assemblages, or queer archives, capable of reinventing themselves into new models of storage and transmission in response to the contours of queer life. As a contribution to the archival turn in the humanities and social sciences, an additional aim of this study is to palpate the transhistorical and transmedial reverberations of the queer archive as a storytelling technology, as site where queer histories and identities are negotiated and sometimes consolidated, but never fully fixed.
Microvascular Cranial Nerve Palsies in an Arabic Population

description: The incidence of microvascular ocular cranial nerve palsies may be increasing with the prevalence of diabetes in the developing world. We review this problem for the first time in an Arabic population. This is a prospective nonrandomized study of all patients with the diagnosis of microvascular cranial mononeuropathy seen in the Neuro-ophthalmology Clinic at the King Khaled Eye Specialist Hospital between September 1997 and April 1998. Forty-seven patients with microvascular palsies of cranial nerves 3, 4, or 6 were seen in this 8-month period. Compared to previous studies, this group had a stronger association with previously diagnosed diabetes mellitus, more males affected, and a longer duration of the cranial nerve palsy before complete resolution. Five patients had an unusual clinical course that included a second microvascular cranial mononeuropathy before the first palsy completely resolved. Microvascular cranial nerve palsies may occur more frequently in this Arabic population than elsewhere and may have certain unusual features.

description: Background: identifying nutrition- and lifestyle-based risk factors for cognitive impairment and dementia may aid future primary prevention efforts. Objective:We aimed to examine the association of serum vitamin D levels with incident all-cause dementia, clinically characterized Alzheimer’s disease (AD), MRI markers of brain aging, and neuropsychological function. Methods:Framingham Heart Study participants had baseline serum 25-hydroxyvitamin D (25(OH)D) concentrations measured between 1986 and 2001. Vitamin D status was considered both as a continuous variable and dichotomized as deficient (<10 ng/mL), or at the cohort-specific 20th and 80th percentiles. Vitamin D was related to the 9-year risk of incident dementia (n = 1663), multiple neuropsychological tests (n = 1291) and MRI markers of brain volume, white matter hyperintensities and silent cerebral infarcts (n = 1139). Results:In adjusted models, participants with vitamin D deficiency (n = 104, 8% of the cognitive sample) displayed poorer performance on Trail Making B-A (β= –0.03 to –0.05±0.02) and the Hooper Visual Organization Test (β= –0.09 to –0.12±0.05), indicating poorer executive function, processing speed, and visuo-perceptual skills. These associations remained when vitamin D was examined as a continuous variable or dichotomized at the cohort specific 20th percentile. Vitamin D deficiency was also associated with lower hippocampal volumes (β= –0.01±0.01) but not total brain volume, white matter hyperintensities, or silent brain infarcts. No association was found between vitamin D deficiency and incident all-cause dementia or clinically characterized AD. Conclusions:In this large community-based sample, low 25(OH)D concentrations were associated with smaller hippocampal volume and poorer neuropsychological function.

description: G-protein-coupled receptors are membrane proteins that are regulated by a small family of arrestin proteins. During formation of the arrestin–receptor complex, arrestin first interacts with the phosphorylated receptor C terminus in a pre-complex, which activates arrestin for tight receptor binding. Currently, little is known about the structure of the pre-complex and its transition to a high-affinity complex. Here we present molecular dynamics simulations and site-directed fluorescence experiments on arrestin-1 interactions with rhodopsin, showing that loops within the C-edge of arrestin function as a membrane anchor. Activation of arrestin by receptor-attached phosphates is necessary for C-edge engagement of the membrane, and we show that these interactions are distinct in the pre-complex and high-affinity complex in regard to their conformation and orientation. Our results expand current knowledge of C-edge structure and further illuminate the conformational transitions that occur in arrestin along the pathway to tight receptor binding.
