Finding the Origins of Musical Taste
Why do some people claim to “listen to all music” while others prefer one genre? Existing research on musical tastes suggests there is a lot more than mere taste that influences an individual’s opinions of particular musical genres (Benzecry and Collins 2014; Peterson and Simkus 1992; Vuolo, Uggen, and Lageson 2014). To investigate this, I look to the theory of cultural omnivorousness (Peterson and Simkus 1992), which suggests that high status individuals may no longer prefer a select few musical genres, but conversely a broad and eclectic arrangement of genres. Using data on musical preferences likes from the 1993 General Social Survey of 828 respondents, I link literatures on cultural omnivorousness (Peterson and Simkus 1992), cultural capital (Bourdieu 1984), musical taste, and prestige by proposing that the patterns of an individual’s musical preference can be predicted through their educational attainment and income. Controlling for the age of the respondent, the multivariate regression analyses find educational attainment to be the only significant predictor of musical preferences, with neither income nor age having relationships with musical preferences. I suggest, therefore, that the theory of cultural omnivorousness is upheld, as respondents with higher levels of educational attainment liked more musical genres
Point of Care Healthcare Quality Control for Patients Using Mobile Devices
The advances made in the domain of mobile telecommunications over the last decade offer great potential for developments in many areas. One such area that can benefit from mobile communications is telemedicine, which is the provision of medical assistance, in one form or another, to patients who are geographically separated from the healthcare provider. When a person is ill, individual attention from medical professionals is of the utmost importance until they have returned to full health. However, people who suffer with long term and chronic illnesses may need life long care and often must manage their condition at home. Many chronically ill patients manage their condition themselves and perform ‘self-testing’ with Point of Care Test (POCT) equipment as part of this condition management. When a specimen sample is analysed at home with a POCT device, a result is available to the patient almost immediately, but the result cannot be proven to be plausible for the patient unless it is validated by the hospital systems. In addition to this the hospital is unaware of the patients condition and progress between hospital visits. This research addresses some of the issues and problems that fact patients who use POCT equipment to ‘self-manage’ their condition at home. Using mobile phone technologies and the Java platform, three alternative methods for providing patients with a service of POCT result validation and storage was designed. The implementation and test of these systems, proves that a mobile phone solution to the issues associated with patient self-testing is possible and can greatly contribute to the quality of patient care
Relational Composition of Physical Systems: A Categorical Approach
In this master's thesis, we rigorously develop two frameworks of relational
composition of systems using tools from category theory. The first framework
addresses port-Hamiltonian systems, which are dynamical systems whose dynamics
are connected to flows of energy across a boundary. The second framework
addresses thermostatic systems, which are descriptions of equilibria in
physical systems using entropy. We also review necessary subjects to develop
these frameworks from a category-theoretic viewpoint, including inear algebra,
differential geometry, and convex geometry
Selling Catholicism: Bishop Sheen and the Power of Television
When the popularity of Milton Berle\u27s television show began to slip, Berle quipped, At least I\u27m losing my ratings to God! He was referring to the popularity of Life Is Worth Living and its host, Bishop Fulton J. Sheen. The show aired from 1952 to 1957, and Sheen won an Emmy, beating competition that included Lucille Ball, Jimmy Durante, and Edward R. Murrow.
What was the secret to Sheen\u27s on-air success? Christopher Lynch examines how he reached a diverse audience by using television to synthesize traditional American Protestantism with a reassuring vision of Catholicism as patriotic and traditional. Sheen provided his viewers with a sense of stability by sentimentalizing the medieval world and holding it out as a model for contemporary society. Offering clear-cut moral direction in order to eliminate the anxiety of cultural change, he discussed topics ranging from the role of women to the perils of Communism.
Sheen\u27s rhetoric united both Protestant and Catholic audiences, reflecting--and forming--a vision of mainstream, postwar America. Lynch argues that Sheen\u27s persuasive television presentations helped Catholics gain social acceptance and paved the way for religious ecumenism in America. Yet, Sheen\u27s work also sowed the seeds for the crisis of competing ideologies in the modern American Catholic Church.
Christopher Lynch is an assistant professor and freshman seminar director in the Department of Communication and Theatre at Kean University, New Jersey.
Not only was Fulton Sheen the only ostensibly religious broadcaster to ever be commercially viable on television, but he enjoys residual popularity today. —John P. Ferre, University of Louisville

Design of a wireless system for patient-hospital communciation and result validation in point of care testing
This paper discuses mobile phone (cell phone) and wireless applications for linking patients who manage their healthcare outside the hospital using point of care testing (POCT) to hospital information systems (HIS). Certain medical conditions require patients to manage their healthcare by performing on themselves POC testing and act faithfully on the result. This raises quality control issue, as these POC samples and testing procedures are not independently overseen by professional hospital staff. In hospitals, samples taken by clinicians are validated by hi-tech computerised validation systems to ensure plausibility, before physicians rely on them. Patients in the home must often use results from these POCT to determine medication dosage or to monitor their condition. Thus, there is a need to implement a system of result validation, either locally or by the hospital validation system itself for people testing with POCT devices
Categorical Data Structures for Technical Computing
Many mathematical objects can be represented as functors from
finitely-presented categories to . For instance,
graphs are functors to from the category with two parallel arrows.
Such functors are known informally as -sets. In this paper, we
describe and implement an extension of -sets having data attributes
with fixed types, such as graphs with labeled vertices or real-valued edge
weights. We call such structures "acsets," short for "attributed
-sets." Derived from previous work on algebraic databases, acsets
are a joint generalization of graphs and data frames. They also encompass more
elaborate graph-like objects such as wiring diagrams and Petri nets with rate
constants. We develop the mathematical theory of acsets and then describe a
generic implementation in the Julia programming language, which uses advanced
language features to achieve performance comparable with specialized data
structures.Comment: 26 pages, 7 figure
Humor at work: using humor to study organizations as a social process
Humor is usually associated with trivial or non-serious banter; it is however a significant factor in the construction of organizational culture. This work provides an experience based organizational account of how organizations are produced and reproduced, as well as how organizational interaction is coupled with structure. This dissertation is based on two ethnographic studies: the first, a year-long study of a hotel kitchen, and the second, a three-year study of a private boarding school. This long term examination of an organization??s interaction is used to illustrate how organizational interaction produces the duality of organizational structuration overtime. An ethnographic communication-focused approach provides methods for recognizing multiple sites and levels of the Structuration process. As a result, this approach provides a major contribution to understanding the process of Structuration through agents?? actions in the context of their organizational culture
Aspects of slurry management on pig farms.
End of Project ReportThe objectives of manure or slurry management on intensive pig farms
are the provision of adequate slurry storage capacity and the efficient
recycling of the slurry nutrients for crop production. However, recent
surveys of pig slurry dry matter suggest there is excessive dilution of
raw pig slurry with water. This has two important implications for
management. The first is greater storage capacity will be required due
to the increased volume of slurry generated. Slurry storage is expensive.
For example, a 350 sow unit adding 10 weeks storage needs to
invest £50,000. Secondly, evidence from the literature indicates an
improved slurry nitrogen efficiency with the more dilute manure. The results of field trials showed that higher dry matter pig slurries
reduced the relative efficiency of pig slurry nitrogen for second cut
silage production. This is probably linked to reduced ammonia volatilisation
losses, consequent to the less viscous nature of dilute slurry
which permits a more rapid infiltration of the ammonium nitrogen into
the soil. The use of a band spreader or shallow injection rather than
the conventional splash plate were shown to increase the efficiency of
pig slurry nitrogen for grass silage production. Therefore, the potential
for the higher pig slurry dry matter, required for cost effective storage/
handling costs, to reduce the efficiency of its nitrogen for grass
silage production can be partially offset by using band spreaders or
shallow injection spreading systems. These have the added advantage
of reducing odour emissions from the land spreading operation.Teagasc Walsh Fellowship Programm
Dynamics of cardiovascular ageing
We gain wrinkles and lose hair, as we age, but our bodies also change in less obvious but much more important ways. This project studied the age-related alterations that occur in the cardiovascular system – the heart, lungs and network of arteries and veins that carry oxygenated blood and nutrients to every cell of the body and remove the waste products of metabolism. It was already known that the phase of breathing affects the rate at which the heart beats, but that this effect decreases as we age. The research has associated this reduction in heart-lung interaction with changes in the endothelium, the inner lining of all the blood vessels. It involved making non-invasive measurements of blood flow in the skin of 200 healthy subjects of all ages. The analysis focused on very low frequency oscillations in blood flow that can give a measure of the state of the endothelium. The main conclusions are, first, that to age healthily, you should look after your endothelium and, secondly, that it should be feasible to design an instrument for assessing endothelial health – an endotheliometer
