A sensorimotor basis of speech communication
Full text linkThis dissertation presents the development of sensorimotor primitives as a means of constructing a language-agnostic model of speech communication. Insights from major theories in speech science and linguistics are used to develop a conceptual framework for sensorimotor primitives in the context of control and information theory. Within this conceptual framework, sensorimotor primitives are defined as a system transformation that simplifies the interface to some high dimensional and/or nonlinear system. In the context of feedback control, sensorimotor primitives take the form of a feedback transformation. In the context of communication, sensorimotor primitives are represented as a channel encoder and decoder pair. Using a high fidelity simulation of articulatory speech synthesis, these realizations of sensorimotor primitives are respectively applied to feedback control of the articulators, and communication via the acoustic speech signal. Experimental results demonstrate the construction of a model of speech communication that is capable of both transmitting and receiving information, and imitating simple utterances.Submission original under an indefinite embargo labeled 'Open Access'.

Risk Assessment in Economic Feasibility Analysis: The Case of Ethanol Production in Texas
Full text linkThe objective of this study is to demonstrate the benefits of quantifying the economic viability of a proposed agribusiness under risk relative to a feasibility study which ignores risk. To achieve this objective, the economic viability of a 50 MMGPY ethanol facility in Texas is analyzed over a 10-year period in two ways: with no risk and with historical risk for prices and costs.Risk and Uncertainty,

Interpretation of COVID-19 Swab Statistics
No full textEach day during the current COVID-19 pandemic many countries report the number of diagnostic swabs performed and the number of positive cases found. These data help to predict the immediate course of the public health emergency. However, their interpretation is non-trivial because the more tests performed, the greater the number of positive cases that will be found. In this document we propose a method for interpreting the data and we apply it to data from Italy.The author can be contacted at "[email protected]". This and another method are implemented in a program available at "https://zenodo.org/record/4633930#.YGrtwRJ8KAk"
The 'true use of reading' : Sarah Fielding and mid eighteenth-century literary strategies.
No full textPhDThe aim of this thesis is to explore, by examining her life and
works, how Sarah Fielding (1710-68) established her identity as an author.
The definition of her role involves her notions of the functions of
writing and reading.
Sarah Fielding attempts to invite readers to form a sense of ties
by tacit understanding of her messages. As she believes that a work
of literature is produced through collaboration between the writer and
the reader, it is an important task in her view to show her attentiveness
toward reading practice. In her consideration of reading, she has two
distinct, even opposite views of her audience: on the one hand a familiar
and limited circle of readers with shared moral and cultural values and
on the other potential readers among the unknown mass of people. The
dual targets direct her to devise various strategies. She tries to
appeal to those who can endorse and appreciate her moral values as well
as her learning. Her writings and letters testify that she is sensitive
to the demands of the literary market, trying to lead the taste of readers
by inventing new forms.
The thesis opens with an overview of Sarah Fielding's career,
followed by a consideration of her critical attention to the roles of
reading. I go on to examine the narrative structures and strategies
she deploys, with a particular emphasis on her use of the epistolary
method. The following chapter deals with her attention to the reading
of the moral message tangibly embodied in her educational writing. It
is followed by an analysis of the activity which earned her a reputation
as a learned woman. Various as the forms of her works are, they invariably
reflect her attempt to balance herself between the two demands of
inventiveness and familiarity

Full text linkObstacles on the path: An exposition of the experience of car-free living
No full textThe contemporary focus by local and central government on the promotion of sustainable transport options has highlighted the need for commuting to move away from the current dependence on private cars to more public and active (walking and cycling) modes of transport. Given the prominence of the motor car in personal transport options however, choosing to live car-free in this car dependent culture appears at first glance to be an irrational choice. This research explores the lived experiences of a group of Hamilton residents who have made such a choice. Using a grounded theory approach, the thesis presents the results of interviews with nine car-free Hamilton residents who shared their personal transport stories, which include their childhood experiences, but focus on their current everyday practices and experiences. Through semi-structured interviews, the costs and benefits of a car-free lifestyle are articulated and analysed. Their motivations for choosing to forgo cars and their solutions for overcoming potential barriers to car-free living are also reported and explored. The collected data generated a range of themes which are presented in three chapters, each covering a specific aspect of the participants’ stories. The first group of themes relate to the public sphere, the second to the private realm and the final group emanates from specific elements of car-free living that the thesis sought to clarify through the participants’ stories. The key finding is that living car-free within Hamilton City is viewed by the participants as a well reasoned and eminently sensible choice, which produces multiple benefits. In addition to their reduced environmental footprints, the participants value the social interaction associated with active and public transport. Their consensus is that they are healthier, wealthier and more involved members of the community. The most problematic areas of living without a car were associated with recreational and social activities, which often do not coincide with public transport schedules or involve distances too great for active transport. The benefits far outweigh any disadvantages however, and ultimately, this thesis concludes that a motor car is not necessary for the everyday activities of urban living in Hamilton and any associated inconveniences are not as insurmountable as generally imagined

Comparative Effectiveness of Moderna, Pfizer-BioNTech, and Janssen (Johnson & Johnson) Vaccines in Preventing COVID-19 Hospitalizations Among Adults Without Immunocompromising Conditions — United States, March–August 2021
Full text linkThree COVID-19 vaccines are authorized or approved for use among adults in the United States (1,2). Two 2-dose mRNA vaccines, mRNA-1273 from Moderna and BNT162b2 from Pfizer-BioNTech, received Emergency Use Authorization (EUA) by the Food and Drug Administration (FDA) in December 2020 for persons aged ≥18 years and aged ≥16 years, respectively. A 1-dose viral vector vaccine (Ad26.COV2 from Janssen [Johnson & Johnson]) received EUA in February 2021 for persons aged ≥18 years (3). The Pfizer-BioNTech vaccine received FDA approval for persons aged ≥16 years on August 23, 2021 (4). Current guidelines from FDA and CDC recommend vaccination of eligible persons with one of these three products, without preference for any specific vaccine (4,5). To assess vaccine effectiveness (VE) of these three products in preventing COVID-19 hospitalization, CDC and collaborators conducted a case-control analysis among 3,689 adults aged ≥18 years who were hospitalized at 21 U.S. hospitals across 18 states during March 11-August 15, 2021. An additional analysis compared serum antibody levels (anti-spike immunoglobulin G [IgG] and anti-receptor binding domain [RBD] IgG) to SARS-CoV-2, the virus that causes COVID-19, among 100 healthy volunteers enrolled at three hospitals 2-6 weeks after full vaccination with the Moderna, Pfizer-BioNTech, or Janssen COVID-19 vaccine. Patients with immunocompromising conditions were excluded. VE against COVID-19 hospitalizations was higher for the Moderna vaccine (93%; 95% confidence interval [CI] = 91%-95%) than for the Pfizer-BioNTech vaccine (88%; 95% CI = 85%-91%) (p = 0.011); VE for both mRNA vaccines was higher than that for the Janssen vaccine (71%; 95% CI = 56%-81%) (all p<0.001). Protection for the Pfizer-BioNTech vaccine declined 4 months after vaccination. Postvaccination anti-spike IgG and anti-RBD IgG levels were significantly lower in persons vaccinated with the Janssen vaccine than the Moderna or Pfizer-BioNTech vaccines. Although these real-world data suggest some variation in levels of protection by vaccine, all FDA-approved or authorized COVID-19 vaccines provide substantial protection against COVID-19 hospitalization
