Integrating Communication with Conspicuity to Enhance Vulnerable Road User Safety: ArroWhere Case Study
Creators: name: Shoji, Takuro

Publisher: name: Multidisciplinary Digital Publishing Institute
Year: 2019

description: This paper presents findings from a research study into the role that communication plays in the safety of vulnerable road users (VRUs), including a literature review, a hypothesis, and a case study testing our hypothesis. Many governments and road authorities lack capital or have not made it a priority to implement full VRU safety measures, with many gaps in VRU infrastructure and networks. These gaps leave VRUs to take safety into their own hands, including use of conspicuity aids such as high-visibility wear, helmets, bells, and lights with differing levels of effectiveness. The knowledge gap regarding the conventional wisdom, “be safe, be seen,” is the absence of communication and comprehension between road users (VRUs and vehicles). We hypothesize that communication aids are equally, if not more important than visibility aids for VRU safety. A case study was conducted to measure the effectiveness of several Hi-Viz safety vest designs including online surveys and separate in-field experiments using Instrumented Probe Bicycles. The results suggest that Hi-Viz safety vests using arrow designs (ArroWhere’s proprietary products and designs) similar to those found in the Manual on Uniform Traffic Control Devices (MUTCD) can increase VRU safety until road authorities can fully fund and complete proper and sustainable VRU networks.

description: Neural signals modulate acetylcholinesterase (AChE) expression in skeletal muscle cells. However, the cellular and molecular events mediating these effects are poorly understood. The mechanisms by which nerve-evoked electrical activity and nerve-derived trophic factors regulate the expression of AChE along muscle fibers was therefore elucidated. The contribution of nerve-evoked activity versus intrinsic properties of muscle fibers was assessed for their role in dictating the distinct patterns of AChE expression displayed by fast and slow muscles. We demonstrate that nerve-evoked electrical impulses play a key role in regulating AChE synthesis in these distinct muscle types. We also demonstrate that myogenic precursor cells from fast and slow muscle fibers generate myotubes that display similar patterns of AChE expression. Together, these findings suggest that nerve-evoked electrical activity rather than intrinsic properties of muscle cells is the primary regulator of AChE expression in fast and slow muscles. The importance of transcriptional versus post-transcriptional mechanisms in mediating the activity-dependent regulation of AChE was also determined. We demonstrate that higher levels of AChE mRNA observed in fast versus slow muscles is due to post-transcriptional events. We also show that reductions of AChE mRNA seen in mature denervated muscles cannot be accounted for by a decrease in the rate of AChE gene transcription. Denervation-induced reductions in the levels of AChE mRNA were less pronounced in muscles of developing animals. This attenuated decrease in AChE transcript abundance may be due to a transient enhancement in the transcriptional activity of the AChE gene observed in denervated muscles of developing rats. Transcriptional as well as post-transcriptional mechanisms are therefore important in mediating the activity-dependent regulation of AChE in developing muscles whereas post-transcriptional events are the primary mediators controlling AChE expression in mature muscles. Finally, the activity of several rat AChE promoter fragments in synaptic versus extrasynaptic regions of muscle fibers was assessed to determined whether enhanced transcription of the AChE gene in synaptic nuclei contributes to the accumulation of AChE transcripts at the neuromuscular synapse. Our findings indicate that synapse-specific activity of the AChE gene contributes to localized expression of the enzyme and its mRNA at the neuromuscular junction. Furthermore, we observed that calcitonin gene-related peptide (CGRP) and ciliary neurotrophic factor (CNTF) downregulate AChE expression. The suppressive effects of CGRP and CNTF on AChE expression suggest that a combination of activating and inhibiting signalling cascades may function in concert to regulate the abundance of AChE transcripts at synaptic sites.
"If you go there - you who was never there:" On Contemporary Uses of the Memory of Slavery

Subjects: American literature, slavery

description: Kenneth Warren, in his controversial What Was African American Literature? (2011), argues that while African American literature was once “prospective,” contemporary black writing is “retrospective” and its obsessive preoccupation with the past is the result of nostalgia for the supposedly unified and cohesive black community of Jim Crow times and unwillingness to accept the disappearance of racial particularity after the end of legally sanctioned racial segregation. While some of his points are well taken, nostalgia for the past is not behind the current rememory of slavery in literature, the arts and popular culture. “I know I can’t change the future but I can change the past. It is the past, not the future, which is infinite,” replied Toni Morrison to a question about the genesis of Beloved. By changing the past, however, she aims at changing the future. Neo-slave narratives are works that rewrite the past in order not only to set the historical records straight, but also to heal the collective memory through narrative so that an authentically post-racial community can come into existence. They challenge the divide between past and present, to counter Western amnesia of the traumas of colonization and slavery.

Black Power Is Black Language. Le lingue del ghetto come pratiche di ®esistenza

Subjects: Black English, African diaspora

description: Drawing on the debate on African American English, this paper will explore two pivotal aspects of the issue: the necessary tracing back of the origins and the context that gave birth to Black language as a fundamental issue for a specific social reality, and the identification of those peculiarities (phonetic, morpho-syntactic and lexical) not only proving the complexity of its linguistic status and its diversity from standard English, but also representing all its strength. In particular, by connecting African American Diaspora to more recent trans-Mediterranean routes, the theoretical framework will focus on the creation of new geo-localities and linguistic identities emerged from the multilayered contaminations brought about by global cultural flows. From a linguistic point of view a meaningful example of this process of contact and contamination is the form of Black English used in Italy by some second-generation immigrants as a pidgin adapted to specific communicative purposes that exceed linguistic, national and geographical borders. More specifically, the research will analyze Karima 2G’s aesthetics that might help re-construct the linguistic and cultural history of the color line in Italy through her history of second-generation Liberian-Italian using rap and Black English to open a transatlantic vision of the traces left by the African Diaspora.

description: Lasciando Pamplona, dove nel luglio 1925 avevano assistito alla festa di San Firmino con alcuni loro amici parigini, Ernest e Hadley Hemingway prolungarono la vacanza per godersi insieme qualche momento più tranquillo dopo la frenesia di quell’evento. Andarono a sud, a Madrid, per vedere qualche altra corrida e visitare il Prado, che ben presto divenne uno dei luoghi della città preferiti da Hemingway. Nonostante tutti quei nuovi stimoli, Hemingway a stento riusciva a non pensare all’incredibile settimana che avevano trascorso a Pamplona durante la festa. Tutto quello che era successo là aveva cominciato a fondersi nella sua mente, assumendo nuova vita come materiale per un romanzo. Furono i suoi amici a ispirargli i personaggi: Lady Duff Twysden suggerì il modello per Brett Ashley; Harold Loeb sarebbe diventato Robert Cohn; i tratti di Bill Smith e Donald Ogden Stewart si sarebbero combinati per creare il personaggio di Bill Gorton. Hemingway si accorse di avere le carte in regola per scrivere un grande romanzo. Stava anche arrivando alla conclusione che le vacanze erano un buon momento per dedicarsi alla scrittura. Invece di aspettare fino a quando lui e Hadley sarebbero tornati a Parigi, Hemingway iniziò la stesura del nuovo lavoro a Madrid. Il risultato sarebbe stato Fiesta–Il sole sorge ancora.

Subjects: American literature, civil rights movement

description: Given that “the civil rights movement without its music would have been like a bird without its wings”, music is more and more often acknowledged for being the backbone to the struggles for the civil rights in the US, from the mid-fifties through the mid-sixties. The essay points to the mix of Black music styles – spirituals from the Black Church, union folk songs, soul hits, popular music and even jingles – that often crossed over into each other, offering a complex body of music that often defied an ill-perceived color line. Some examples are offered that provide new food for thought about the folk revival style of African American singer-songwriters like Len Chandler and Jim Collier, about Aretha Franklin’s 1967 recording session at Fame Studios in Muscle Shoals, about the overlooked Wattstax event (and film) that took place at the Los Angeles Coliseum in 1972 (featuring Reverend Jesse Jackson, a roster of Stax artists and blaxploitation icons like Isaac Hayes and Melvin Van Peebles), and about the debated transformations in the singing of the national anthem.

The Route to Identity: Italian Translation and African American Language(s) in Spike Lee's Get on the Bus
Creators: name: Renna, Dora
Publisher: name: Iperstoria
Year: 2019
Subjects: cinema, audiovisual translation, spike lee

description: This paper investigates translation issues emerging from the analysis of Spike Lee’s movie Get on the Bus (1996) and its Italian adaptation, Bus in Viaggio. The choice is motivated by African American Vernacular English (AAVE), used in the film by a group of men that get on the bus to reach the Million Man March in Washington (1995). During the journey, characters will confront each other on different topics, such as African American male identity in that precise moment and for the future, as well as their role within the black community. As in other movies by Spike Lee, the traditional and stereotyped media portrayal of African American people is challenged and subverted. This dialogical construction poses a set of challenges for the translator/adaptor, especially because it is characterised by a use of language that has no equivalent in Italian. (Un)translatability is the main focus of this research: can idiomatic expressions that are typical of a non-standard variety of English be translated? Which translation strategies have been used? These questions will be analysed through a reading of the speech patterns enacted by one of the characters, the wannabe Hollywood star Flip, a stereotyped portrait against whom each character will fight in order to affirm his identity.

Diritto di voto e alfabetizzazione. Bernice Robinson e le Citizenship Schools delle Sea Islands

Publisher: name: Iperstoria

Subjects: American literature; Bernice Robinson

description: American historiography in the last two decades has been paying growing attention to the contribution of women to the African American Freedom Struggle. Women were often the main agents in grassroots experiences, delving on their deep connections to local communities, where they were involved on many levels, including friendship networks or church activities. The experience of Bernice Robinson (1914-1994) is telling in that line: after leaving her native Charleston in her youth, she returned after the war, due to family obligations, carrying the experience of integrated life in New York. She relied on the two trades she had learned in New York, as a seamstress and beautician. She was an active member of NAACP, besides being the cousin of a more widely known activist, Septima P. Clark, who had been fired from her position as a teacher because of NAACP membership. Clark first took her cousin to the interracial Highlander Folkschool, Tennessee, along with an activist from Johns Island, Esau Jenkins. This experience brought to a bold experiment in the education of illiterate adults in the Sea Islands, stretching along the coast of South Carolina and Georgia: the site of an outstanding grassroots experiment in the late ‘50s and early ‘60s. Basic literacy for adults was taught, with the aim of getting them registered for voting, starting with a small class in January 1957, when the literacy test was still the main instrument for excluding African American Southerners from the ballots. Robinson accepted to be a non-professional teacher on the Sea Islands, while keeping her business running in Charleston. She successfully developed original methods for teaching adults. Within a few years she became a full-time activist, holding workshops around the South, cooperating with both SCLC and SNCC. The Citizenship Schools project in 1961 was administered by SCLC, and it spread in the whole South, totaling 900 classes led by non-professional teachers, coordinated by Clark, and 700.000 registrations before VRA was enacted. After the passing of the Voting Rights Act of 1965, Robinson’s experience proved valuable for other organizations involved in literacy projects for migrants. Her personality is a good example of the way in which Southern African American women could develop strategies for civil rights in a very difficult political context, still widely imbued with male chauvinism.

Remembering the Reverend: An Analysis of Obama's Speeches Commemorating Martin Luther King
Creators: name: Franceschi, Valeria
Publisher: name: Iperstoria

Subjects: political discourse, cognitive metaphors, Obama

description: In the wake of the 50th anniversary of the Selma-Montgomery marches, the memory of Martin Luther King and his struggles for equality still survives in the minds of American citizens. The echo of his actions and words endures pervasively in Barack Obama’s own rhetoric; a connection between King and Obama was drawn when the latter became a serious contender for the nomination as a Democratic candidate in early 2007, due to their shared ethnicity as AfricanAmericans and to the historical significance of having a strong African-American candidate running for the presidency. This study investigates how metaphors and myths are employed in Martin Luther King’s and Obama’s rhetoric from a cognitive linguistic perspective, by applying conceptual metaphor theory (Lakoff and Johnson 1980; Fauconnier and Turner 1994, 1998) applied to political discourse analysis (Charteris-Black 2004, 2011, 2014). The analysis is carried out on 7, speeches delivered by Obama between 2006 and 2015, with the purpose of remembering and celebrating the achievements and activism of Martin Luther King. Results show how Obama builds and expands on the ideas and myths employed by King in his own speeches to create support for himself as a dependable and rightful leader for America, both before and after his election to office.

Subjects: CE-Kennzeichnung

description: In Europe, the Construction Products Regulation sets harmonized conditions for the marketing of construction products with the objective of protecting the building users' health. However, until now only three European countries have implemented requirements for the assessment of VOC emissions from construction products. The European Commission has recognized the insufficient implementation of health require ents and is therefore currently planning the issue of a delegated act on the communication of VOC emissions from construction products in the form of "VOC Classes". A key prerequisite for defining the VOC classes is the completion of the EU-LCI list currently being carried out by a group of experts from ten European countries. This paper reports on the development of the VOC class concept, the progress of the EU-LCI harmonization framework and Germany's current efforts to ensure a high health protection level of building users and avoid dangers from construction product emissions.

A role for nitric oxide in the pathogenesis of necrotizing enterocolitis: Discovery, evaluation and design of a novel prophylactic therapy.

Subjects: subject: Biology, Molecular.

description: Necrotizing enterocolitis (NEC) is an acute, self-limiting, inflammatory bowel disease of unclear pathogenesis affecting premature infants. It is the most common acquired surgical emergency in the neonatal period. NEC is characterized by necrosis of the bowel wall and may lead to peritonitis, stricture formation with bowel obstruction and lower gastrointestinal hemorrhage. Approximately 10% of premature babies develop NEC with up to 94% of cases seen in infants born at less than 36 weeks gestation. As more and more premature infants survive the neonatal period, it is expected that the incidence of this disease will increase. Briefly, the protocol involves laparotomy of anesthetized animals, creation of closed loops from terminal ileum to proximal colon which are injected with acidified casein test solution separated by saline injected control loops. Because NO is involved in neural control of intestinal motility and mucosal protection, we sought to evaluate the effects of manipulation of the nitrergic system on experimentally induced NEC in this model. Developmental changes in piglet intestinal motility were then documented in vivo, as well as those modifications induced by systemic stimulation or inhibition of NO availability. Our results have shown the presence of an ontogenically determined pattern of fasting intestinal motor activity, which is more susceptible to nitrergic manipulation in earlier developmental stages as documented through motility responses of the terminal gut. NO synthase activity was then measured in different regions of the developing piglet gut as well as in various layers of the piglet gut wall and compared to the activity found in NEC-induced gut specimens (test loops) at different stages of development and in different gut regions. Total NOS, iNOS and cNOS activity was assayed using the conversion of 14C L-arginine to 14C citrulline in full thickness gut, and in muscular and mucosal layers separated under the dissecting microscope. The potential therapeutic applications of these findings in preventing or attenuating NEC-induced intestinal damage in premature infants led to the development of a, now ongoing, clinical trial evaluating the effects of intravenous L-arginine administration in premature infants. It is expected that, based on preliminary data, a multi-centre clinical trial may lead to the prophylactic use of L-arginine as a treatment modality for NEC. (Abstract shortened by UMI.)

description: The cutoff properties of triangular photonic crystal fibers with different core dimensions have been deeply investigated. In particular, 7-rod core fibers, obtained by removing the air-holes belonging to the first ring, as well as the central one in the fiber cross-section, have been considered. A phase diagram which describes the regions of single-mode and multi-mode operation for these large mode area fibers has been calculated with two different approaches. Simulation results have demonstrated that, for a fixed air-filling fraction, triangular photonic crystal fibers with a wider silica core region are single-mode in a smaller wavelength range. As a consequence, also the endlessly single-mode region of 7-rod core triangular fibers is smaller than that of 1-rod core ones. However, by properly choosing low air-filling fraction and relatively small hole-to-hole distance, 7-rod core photonic crystal fibers can provide high effective area values, as well as single-mode operation, without the problem of leakage losses.

description: Potential effects of demographics, personality, and ideological attitudes on the number of news sources consumed should be investigated. The number of news sources consumed, in turn, was seen as inverse proxy for the susceptibility to be caught in “filter bubbles” and/or “echo chambers” (online), which are hotly discussed topics also in politics. A sample of 1,681 (n ¼ 557 males) participants provided data on demographics, the Big Five as well asRight-Wing Authoritarianism (RWA) alongside the number of different news sources consumed and current voting preferences. Results showed that age (positively), gender (higher in males), Openness (positively), and RWA (negatively) predicted the number of different news sources consumed. The group of participants consuming news exclusively offline showed highest scores in Conscientiousness and lowest scores in Neuroticism compared to the “news feeds only” and the “news feeds and online” groups. However, less than 5% of the participants exclusively consumed news via news feeds of social networking sites. Participants who stated that they would not vote reported the lowest number of different news sources consumed. These findings reveal first insights into predisposing factors for the susceptibility to be caught in “filter bubbles” and/or “echo chamber” online and how this might be associated with voting preferences.

description: In the last twenty years there has been a growing desire to devolve justice interventions to the level of the community. An example of one such initiative is the justice committee program, an extrajudicial program set up in a number of Canadian communities to address minor youth cases, and cases involving Aboriginal people. This thesis is a capacity assessment of justice committees in Aboriginal communities in Quebec. With the help of literature on restorative community justice, crime prevention and building sustainable community programs, this thesis explores the recommended capacities for the implementation of sustainable justice committees, as well as the capacities perceived to be currently available to some justice committees in Aboriginal communities in Quebec. Through personal observations gathered during my work with justice committees in the past and interviews with various individuals working closely with justice committees in Quebec, this thesis found that a number of capacities were either lacking or were sporadically available to the communities studied. It concludes that with a common vision of the program's purpose, careful consideration of a community's ability to effectively intervene, and increased collaboration, resources and training; justice committees will be more likely to be implemented in a sustainable manner.

Subjects: subject: Health Sciences, Oncology.

description: Glioblastoma multiforme, a high grade malignant astrocytoma, is the most common and mortal intracranial tumor in adults. The median survival time for glioblastoma patients remains from 9--12 months despite aggressive treatment programs. These high-grade central nervous system tumors bear genetic and molecular aberrations that result in innate chemoresistance to commonly used chemotherapeutic agents. The main focus of this thesis is on exploring signaling events downstream of phosphoinositide 3-kinase (PI3-K) in glioblastoma multiforme in attempts to discover molecular targets that may be highly specific and thus less toxic therapeutic targets. The PI3-K pathway is constitutively activated in glioblastoma. The Protein Kinase C family of serine/threonine kinases is activated downstream of PI3-K. Our focus is placed on a member of the atypical protein kinase C subfamily called, atypical PKC iota. We finally began examining the role of atypical PKC iota and invasion in U87MG glioblastoma cells using scratch/wound assays. (Abstract shortened by UMI.)

description: Little is known about the relative cost-effectiveness (CE) of different cardiac rehabilitation (CR) program designs and how CE is influenced by a patient's clinical and demographic characteristics. The aim of this study was to assess the 2-year incremental cost-utility of a distributed (12-month, 33-session) CR program to that of a standard (3-month, 33-session) CR program as assessed from the perspective of the cardiac health care system. 306 Patients (mean age = 58.4 years, SD+/-9.7) with CAD were randomized to either standard or distributed CR. Program delivery costs, cardiac health care use, QALYS were tracked over a two-year period. The standard CR intervention was found to be dominant, resulting in both a cost saving and larger gains in QALYs in the 2-years following initiation of CR. Important differences were noted in CE of CR across cardiac risk strata and diagnosis groups, suggesting patients may benefit from triage to available CR models.
Tablet technology to facilitate improved interaction and communication with students studying mathematics at a distance

description: Teaching and learning of mathematics is challenging when lecturer and students are separated geographically. While student engagement and interaction with the course, with other students and with the lecturer is vital to mathematics learning, it is difficult to facilitate this electronically, because of the nature of mathematics. With tablet technology now becoming ubiquitous and many new and inexpensive models entering the market, it is timely to investigate how the distance student experience in mathematics can be impacted by the use of tablet technologies. This paper reports on a case study of a first year mathematics course at a regional Australian university, where distance students were provided with affordable tablet PCs. An investigation of the impact of this technology on engagement and interaction is at the centre of this study. Evidence from journals, students’ assessment submissions, screen snippets, student communication and formal student evaluations is analysed. It was found that distance students acknowledged the value of tablets for communicating mathematics, particularly for assignment submission and feedback, but they also recognized the potential for easier interaction with content and the lecturer. This paper highlights the specific benefits and challenges tablet PCs present to the learning experiences in mathematics within the distance context.
Water extraction from the atmosphere

Subjects: subject: Engineering, Chemical.

description: This investigation is driven by the desire to find an alternative method of obtaining fresh water. More specifically, fresh water is to be obtained by condensation of atmospheric water vapor on a surface maintained below the dew point by a radiative heat loss from its surface to the night sky. To properly simulate the condensation process, an accurate estimation of the effective sky temperature is required. To estimate the effective night sky temperature an experimental system, consisting of a series of metal plates embedded on a heat transfer panel, a weather station and a control system, was built. The temperature of each plate was controlled using an electric flat-plate heater. A control loop was implemented to ensure that the heat transfer panel was adjusted automatically to always be oriented perpendicular to the wind direction. In addition to the effective night sky temperature, the experimental system was designed to estimate the convective heat transfer coefficient between the plates and ambient air as well as the surface emissivity of the plates. The results obtained from theoretical analyses and preliminary experiments are presented and discussed. Special emphasis was given to mathematical solution of the system of equations that need to be solved to obtain the effective sky temperature. It was shown that, although the solution of the system of equations was straightforward for the direct heat transfer problem, there was a serious difficulty to solve the inverse heat transfer problem to retrieve the desired parameters.
On neural processing in the ventral and dorsal visual pathways using the programmable Graphics Processing Unit

Subjects: subject: Computer Science.

description: We describe a system of biological inspiration that represents both pathways of the primate visual cortex. Our model is applied to multi-class object recognition and the creation of disparity maps from stereo images. All processing is done using the programmable graphics processor; we show that the Graphics Processing Unit (GPU) is a very natural platform for modeling the highly parallel nature of the brain. Each visual processing area in our model is closely based on the properties of the associated area within the brain. Our model covers areas V1 and V2, area V3 of the dorsal pathway and V4 of the ventral pathway of the primate visual cortex. Our model is able to programmatically tune its parameters to select the optimal cells with which to process any visual field. We define a biological feature descriptor that is appropriate for both multi-class object recognition and stereo disparity. We demonstrate that this feature descriptor is also able to match well under changes to rotation, scale and object pose. Our model is tested on the Caltech 101 object dataset and the Middlebury stereo dataset, performing well in both cases. We show that a significant speedup is achieved by using the GPU for all neural computation. Our results strengthen the case for using both the GPU and biologically-motivated techniques in computer vision.

description: This essay analyses a corpus of online articles dealing with models’ rights collected in the press section of the “Model Alliance” website. The articles (about 60, plus the related blogs and forums) were originally published in various newspapers and magazines between 2010 and 2013, and they are an interesting object of analysis for the linguist who intends to investigate how language is used to build up semantically and syntactically coherent forms of discourse about social and cultural issues that are perceived as yet “unexplored.” The analysis develops along two main lines: 1. a quantitative and qualitative lexical analysis based on semantic fields theory and discourse analysis, during which ten key topics (age, education, health, body, work, money, rights, law, sex, power) were identified and then grouped together into five semantic fields and 2. the use of semantic, morphological and rhetorical strategies, with particular emphasis on forms of negativization as well as on the use of modifiers, prefixes and suffixes. The study has confirmed the hypothesis that journalistic language needs to find a “voice” when dealing with new and contested topics. In fact, particularly in the first phase (2010-2012), journalistic discourses about models’ rights presented a more tentative style compared to more consolidated subjects covered in news reports.

Subjects: subject: Language, Linguistics.

description: The characteristics of automated learning and generalization, and of graceful degradation in the face of unforeseen input, give neural networks interesting potential for machine translation (MT). However, the field of connectionist MT has been little explored by researchers. This thesis provides an introduction to neural network concepts and summarizes and reviews the research in the field of connectionist MT. It describes the building, training and testing of TransNet, an embryonic neural network that translates weather reports from English into French. TransNet uses an innovative bigram (word pair) data representation which makes it possible to take some account of word order in the processing.
La storia al tempo della politica. Le produzione teatrali di Tutto è vero (Enrico VIII) nel Novecento
Creators: name: Gallo, Carmen

description: The paper explores the main features of Shakespeare and Fletcher’s All is True, or Henry VIII (1613) through its twentieth-century productions. The play was included in the famous 1623 Folio among the histories (Fletcher’s co-authorship had not been acknowledged yet and it is still debated today) by the editors who probably dismissed the original or alternative title, All is True, and adopted The Famous History of the Life of King Henry VIII so as to strengthen the contiguities between this late work, revolving around one of the most controversial figure of Tudor dynasty, and the previous histories. Nonetheless, the original title and its insistence on “truth” is constantly alluded throughout the play, whose main theme is the use of propaganda, rumors, slanders and defamation as means of political action. This is probably one of the reasons why in the 20th century a few directors chose this play to reflect on the dynamics of modern politics and on the rhetoric of politics in the age of information. Their productions may be split into two main scenic readings: a conservative one, faithful to the Shakespearean tradition established by the Victorians and focused on the ceremonialist and nationalist aspects of the play; and a more radical one, which underlines the hypocrisy of modern politics and the emptiness of its propagandistic practices. The paper reconstructs the pivotal moments of the two performative lines, and analyses the main features and the historical contexts of the productions from Gray’s direction of the play (1931) until Doran’s 1996 e 1998 productions, which significantly restored the title All is True.

The effect of spatial statistics of hydraulic conductivity and distribution coefficient fields on solute transport.
Creators: name: Luffman, Ingrid Elizabeth.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1997
Subjects: subject: Hydrology.

description: The purpose of this research is twofold. First, a tool is developed to assist in the reproduction of field correlation scenarios for input into a flow and transport simulator. Second, this tool is used to generate random fields with several different velocity/retardation relationships typical of the Canada Forces Base Borden aquifer in order to determine the effect of this relationship on the retardation and dispersive processes, specifically on the macrodispersivity. The second section of the research investigates the effect of different types of spatial statistics on the behaviour of a contaminant travelling through saturated, heterogeneous porous media. The non-reactive plume travels significantly farther than the reactive plume, even when considering the effects of retardation. Transverse macrodispersivities are sensitive to changes to neither the correlation within fields, nor the correlation between velocity and retardation fields for both the reactive and non-reactive solute plumes. Longitudinal macrodispersivity for a reactive solute is significantly different than that for a non-reactive solute: the effect of the chemical heterogeneities is to enhance reactive solute macrodispersivities relative to non-reactive macrodispersivities for a negative cross-correlation between velocity and retardation, and to decease reactive solute macrodispersivities relative to non-reactive macrodispersivities when the cross-correlation is positive.

History and Its Others in Afrofuturism
Creators: name: Rieder, John
name: Bacchilega, Cristina
Publisher: name: Iperstoria
Year: 2019
Subjects: American literature, afrofuturism

description: Afrofuturist fiction proceeds from the position of an enslaved, silenced, subaltern Other within the history of the US. It responds by constructing various strategic discontinuities with historical time, including anachronism, apocalypse, and utopia. This talk will survey the use of these narrative strategies in Afrofuturist work by Sun Ra, Octavia Butler, Andrea Hairston, and in the recent anthology of activist science fiction, Octavia’s Brood .

Expression, regulation, and function of the KIT tyrosine kinase receptor and its ligand, stem cell factor, in human epithelial ovarian cancer.
Creators: name: Tonary, Angela Marie.

Subjects: subject: Health Sciences, Obstetrics and Gynecology.

description: This Ph.D. project sought to determine the expression, regulation, and function of the KIT-SCF receptor-ligand system in human epithelia] ovarian cancer. The expression of c- KIT and SCF in normal ovaries, in cultured ovarian surface epithelium (OSE), and in epithelia] ovarian tumors was analyzed. Normal OSE expressed SCF, but not c- KIT ; however, epithelia] invaginations and inclusion cysts often expressed KIT protein. Of 15 benign ovarian tumors and tumors of low malignant potential, 87% expressed c- KIT , and 92% of these co-expressed SCF, suggesting the possibility of autocrine growth regulation. Of 35 malignant ovarian cancers, 71% expressed c- KIT (92% co-expressed SCF), with a trend for decreased c- KIT expression in advanced stage disease. Of 34 patients with malignant tumors for whom follow-up information was available (median follow-up time of 24 months), 9 had tumors that did not express c- KIT , 8 (89%) of whom have died and the remaining 1 has recurrent disease. Of the 25 patients with tumors expressing c- KIT , 56% are still alive, eight of whom have no evidence of disease. Importantly, statistical analysis indicated that patients whose tumors did not express c- KIT had a significantly shorter (p < 0.05) disease-free survival time than patients who had KIT-expressing tumors. Studies were carried out to identify intraovarian growth regulatory factors which may regulate c- KIT and SCF expression in ovarian cancer cells, and to determine whether activated KIT can affect the proliferation and survival of these cells. HEY cells, which co-expressed KIT and SCF, were treated with transforming growth factor (TGF)-α, TGF-β, and dibutyryl cyclic AMP (dbcAMP) and their cellular proliferation and expression of c- KIT and SCF were examined. A series of transfection studies were carried out to determine if enforced c- kit expression inhuman ovarian carcinoma cells could regulate cellular proliferation. Transient transfection of c- kit into HEY cells resulted in decreased proliferation. Similarly, stable transfection of c- kit into A2780-cp cells, which do not express endogenous c- KIT , also resulted in a decreased proliferative rate. In contrast to the ovarian cancer cells, increased proliferation was documented for NIH 3T3 fibroblast cells transiently transfected with c- kit . Together, these results suggest that the positive prognostic value of c- KIT expression in ovarian tumors is related to its negative growth regulatory function in ovarian cancer cells.

Visualizing Black Leadership: The African-American Civil Rights Struggle in Two Contemporary Graphic Novels
Creators: name: Bosco, Stefano
Publisher: name: Iperstoria
Year: 2019
Subjects: American literature, graphic novels

description: Over the last few decades, the genre of the graphic novel has known an unprecedented diffusion as a viable aesthetic form through which its creators can vehicle cultural and political discourses. Especially in the hands of artists belonging to social and racial minorities, the medium has displayed a crucial potential for undermining the master narratives of the dominant (i.e. white) culture, whose traditions of textual and visual representation contributed to the normalization of oppression and exclusion. As they did for other genres of the white American tradition, black artists have recently started to employ graphic narratives so as to question biased views on the African American past, along with the legacy of racialized images through which blacks have been portrayed. Strictly connected to such concern with history and its re-formulation in a predominantly visual medium, there is also an involvement in personal or (auto-)biographical narratives where the self becomes the prism through which one approaches the events and collective experiences defining a particular historical moment. In the case of African-American representations, this biographical element takes up a special resonance for its recalling the tradition of the slave narratives—a genre which was in an already problematic relationship with the ideological uses of white American life-writing. What I am going to explore here is the declination of African-American historical biography within the form of the graphic novel; I will do so by considering two works that thematize black experience during the Civil Rights Movement in different ways and with different purposes—the graphic memoir March, by African American Congressman John Lewis, and the graphic biography King by Afro-Canadian artist Ho Che Anderson.

Oppositional defiant and conduct disorder in attention-deficit/hyperactivity disorder: child and adolescent profiles, diagnostic aids, cognitive markers and implications for the future DSM nomenclature
Creators: name: Perera, Sharnel Miriam
Publisher: name: Swinburne
Year: 2024

description: This research represents the first investigation into the neuro-cognitive profiles of Attention Deficit Hyperactivity Disorder (ADHD) in children and adolescents, particularly in ADHD comorbid with Oppositional Defiant and Conduct Disorder. The results supported a revision of the definition for ADHD in the Diagnostic and Statistical Manual of Mental Disorders. Specifically, the results supported previous claims that ADHD comorbid with Oppositional Defiant and Conduct Disorder constitutes a separate pathological entity in adolescence, and should be classified as such. In childhood, results suggested that a dimensional approach to ADHD diagnosis was more appropriate, which would also help to identify 'at-risk' individuals.
