Measuring Culture And Cultural Change, James Melton '03 Jan 2003

Measuring Culture And Cultural Change, James Melton '03

Res Publica - Journal of Undergraduate Research

Mary Douglas’s grid/group analysis has been a very influential theory for many culture theorists in all fields of the social sciences. There are two good reasons for importance of this theory. It allows for an interaction between the individual and the culture, and it can explain cultural change. There has been some theorizing about the implications of these innovations; however, little empirical work has been done to test these implications. The reason for this, at least partly, is the lack of an indicator capable of easily measuring culture on a wide-scale basis. This paper attempts to solve this problem by …

Market Liberalization, Social Programming, And Stability In Latin America: Are They Compatible?, Gretchen Grabowski '03 Jan 2003

Market Liberalization, Social Programming, And Stability In Latin America: Are They Compatible?, Gretchen Grabowski '03

Res Publica - Journal of Undergraduate Research

A central axiom of political science research holds that government stability is a key determinant of effective governance. Instability makes policymaking difficult and creates an environment that is inhospitable to foreign or domestic economic investment and, in turn, economic growth. Latin America provides an excellent context in which this relationship can be examined. The region was known for its political instability in the 1970s and 1980s, and the vast majority of countries implemented liberal economic reforms during the 1990s. The expectation was that these reforms would yield the economic growth so desperately needed in the region and, along with democratic …

Two Facets Of Competitiveness And Their Influence On Psychological Adjustment, Elaine Kayhan '03 Jan 2003

Two Facets Of Competitiveness And Their Influence On Psychological Adjustment, Elaine Kayhan '03

Honors Projects

This study was conducted to explore the influence of competitiveness as a personality trait on psychological adjustment. Competitiveness was differentiated into two distinct facets referred to as superiority competitiveness and mastery competitiveness. In terms of psychological adjustment, the effects of these facets of competitiveness on depression, loneliness, self-esteem, anxiety, and eating patterns were examined. Questionnaires were used to assess the aforementioned dimensions. The results of the study revealed some noteworthy gender differences. Among females, superiority competitiveness was associated with higher levels of depression. Among males, superiority competitiveness was associated with less loneliness. A significant association was also observed between mastery …

Differences In Friendship Qualities Of Korean And American College Students, Yun-Sun Alexis Bae '03 Jan 2003

Differences In Friendship Qualities Of Korean And American College Students, Yun-Sun Alexis Bae '03

Honors Projects

The present study explored the friendship characteristics of Korean and American college students. Participants (41 Koreans and 87 Americans) described their friends using a questionnaire (Friendship Quality Questionnaire) and an interview. Because of the inadequacy of the interview coding system, the interview data were not analyzed. Analysis of the FQQ supported the hypothesis that Koreans exhibit higher exclusivity than Americans, but no other country effects emerged. Both U.S. and Korean women reported more intimate disclosure than men. Friendship characteristics of Korea and U.S. students were conceptualized using concepts such as Individualism and Collectivism, Confucianism, and the Korean term "cheong" (affection). …

Masculinity And Homophobia: Does Masculine Threat Increase Homophobic Behavior?, Julie M. Longo '03 Jan 2003

Masculinity And Homophobia: Does Masculine Threat Increase Homophobic Behavior?, Julie M. Longo '03

Honors Projects

Threatened masculinity may play a role in homophobic responses in college men. In this study, homophobic or non-homophobic responses to a gay confederate were measured after a masculine threat or no threat manipulation. 49 college men participated in the study: 24 in the masculine threat condition and 25 in the no threat condition. Masculinity level was pre-determined in an initial phase one testing using the Male Role Norms Scale (MRNS). In the masculine threat condition, participants were given a test that was said to measure masculine knowledge and then received false negative feedback. The no threat condition involved a general …

Environmental Impacts Of Modern Agricultural Technology Diffusion In Bangladesh: An Analysis Of Farmers' Perceptions And Their Determinants, S Rahman Jan 2003

Environmental Impacts Of Modern Agricultural Technology Diffusion In Bangladesh: An Analysis Of Farmers' Perceptions And Their Determinants, S Rahman

School of Geography, Earth and Environmental Sciences

Farmers' perception of the environmental impacts of modern agricultural technology diffusion and factors determining such awareness were examined using survey data from 21 villages in three agro-ecological regions of Bangladesh. Results reveal that farmers are well aware of the adverse environmental impacts of modern agricultural technology, although their awareness remains confined within visible impacts such as soil fertility, fish catches, and health effects. Their perception of intangible impacts such as, toxicity in water and soils is weak. Level and duration of modern agricultural technology adoption directly influence awareness of its adverse effects. Education and extension contacts also play an important …

Parenting And Adult Development: Contexts, Processes, And Products Of Intergenerational Relationships, Rob Palkovitz, Loren D. Marks, David W. Appleby, Erin K. Holmes Jan 2003

Parenting And Adult Development: Contexts, Processes, And Products Of Intergenerational Relationships, Rob Palkovitz, Loren D. Marks, David W. Appleby, Erin K. Holmes

Faculty Publications

For the past 50 years, parenthood has been discussed in social science literature as a context of adult development. Theories, anecdotes, and the opinions of laypersons are nearly unanimous: People who become parents and are involved in the raising of children are transformed and follow a different developmental trajectory from people who do not engage in parenting roles. Erickson (1950) suggested that positive adult development reflects care for the next generation, or "generativity," and that parenthood is "the first, and for many, the prime generative encounter" (Erickson, 1964, p. 130). More recently, parenthood has been described as a necessary but …

The Relations Between Knowledge, Search Strategy, And Performance In Unaided And Aided Information Search, John A. Barrick, Brian C. Spilker Jan 2003

The Relations Between Knowledge, Search Strategy, And Performance In Unaided And Aided Information Search, John A. Barrick, Brian C. Spilker

Faculty Publications

Information search is a critical step in resolving complex issues in many different decisionmaking domains. This study examines the relations between knowledge, search strategy, and performance in both unaided and aided information search. The results of an experiment indicates that (a) task-relevant knowledge is directly related to performance in aided but not in unaided information search; (b) in unaided information search, search strategy mediates the relation between knowledge and performance; that is, knowledge indirectly affects performance through its effect on search strategy; and (c) an information search aid moderates both the relation between knowledge and search strategy and the relation …

Indirect Evaporative Cooling Potential In Air-Water Systems In Temperate Climates, Ben Costelloe, Donal Finn Jan 2003

Indirect Evaporative Cooling Potential In Air-Water Systems In Temperate Climates, Ben Costelloe, Donal Finn

Articles

Recent developments have prompted a review of evaporative cooling technology as an effective means of cooling modern deep plan buildings. Prominent among these developments is the success of high temperature sensible cooling systems, particularly, chilled ceilings, which require a supply of cooling water at 14–18 °C. Crucial to the success of evaporative cooling technology, as a significant means of cooling in modern applications, is the ability to generate cooling water, in an indirect circuit, at a temperature which closely approaches the ambient adiabatic saturation temperature (AST) or wet bulb temperature (WBT). Recent experimental research has demonstrated that it is technically …

Automated Rating Of Esl Essays, Deryle W. Lonsdale, Diane Strong-Krause Jan 2003

Automated Rating Of Esl Essays, Deryle W. Lonsdale, Diane Strong-Krause

Faculty Publications

To date, traditional NLP parsers have not been widely successful in TESOLoriented applications, particularly in scoring written compositions. Re-engineering such applications to provide the necessary robustness for handling ungrammatical English has proven a formidable obstacle. We discuss the use of a nontraditional parser for rating compositions that attenuates some of these difficulties. Its dependency-based shallow parsing approach provides significant robustness in the face of language learners’ ungrammatical compositions. This paper discusses how a corpus of L2 essays for English was rated using the parser, and how the automatic evaulations compared to those obtained by manual methods. The types of modifications …

Study Of Structure And Quality Of Different Silicon Oxides Using Ftir And Raman Microscopy, C. Moore, T. S. Perova, B. Kennedy, Kevin Berwick, I. I. Shaganov, R. A. Moore Jan 2003

Study Of Structure And Quality Of Different Silicon Oxides Using Ftir And Raman Microscopy, C. Moore, T. S. Perova, B. Kennedy, Kevin Berwick, I. I. Shaganov, R. A. Moore

Articles

In this work, SiO2 and fluorine and phosphorous doped SiO2 thin films are investigated using FTIR and Raman techniques. FTIR spectroscopy was performed at normal and oblique incidence of the probe beam in transmission and reflection modes. The effect of polarisation and angle of incidence of the probe beam is examined for the case of reflection mode. Infrared spectra taken from doped oxides show that the structure changes with the passage of time. Alternate methods to calculate the thickness of the doped film are therefore discussed. Infrared spectra of electron beam evaporated oxides give valuable information on their …

Pid Compensation Of Time Delayed Processes 1998-2002: A Survey, Aidan O'Dwyer Jan 2003

Pid Compensation Of Time Delayed Processes 1998-2002: A Survey, Aidan O'Dwyer

Conference papers

A time delay may be defined as the time interval between the start of an event at one point in a system and its resulting action at another point in the system. Delays are also known as transport lags or dead times; they arise in physical, chemical, biological and economic systems, as well as in the process of measurement and computation. Methods for the compensation of time delayed processes may be broadly divided into proportional integral derivative (PID) based controllers, in which the controller parameters are adapted to the controller structure, and structurally optimised controllers, in which the controller structure …

“Rocky Mountain Entrepreneur: Robert Campbell As A Fur Trade Capitalist.”, Jay H. Buckley Jan 2003

“Rocky Mountain Entrepreneur: Robert Campbell As A Fur Trade Capitalist.”, Jay H. Buckley

Faculty Publications

Between 1825 and 1835 Robert Campbell emerged as a fur trade entrepreneur. Campbell served as clerk for Ashley-Smith, as brigade leader for Smith, Jackson, and Sublette, and supplier and financier for the Rocky Mountain Fur Company. Campbell quickly became a dominant figure in the American fur trade. In addition to leading fur brigades, Campbell and his partner William Sublette built several trading posts (most notably Fort Laramie), supplied the annual rendezvous, and challenged John Jacob Astor's American Fur Company on the Missouri River. Through it all, Campbell's business acumen helped him pursue economic opportunities that paved the way for future …

Solution Of The Navier-Stokes Equations For Transonic Propeller Flows, Fergal Boyle Jan 2003

Solution Of The Navier-Stokes Equations For Transonic Propeller Flows, Fergal Boyle

Conference Papers

The three-dimensional, compressible, viscous flow field around a general propeller geometry with the inflow at zero angles of incidence and yaw is computed using a Reynolds-Averaged Navier-Stokes equations solver. Results from validation test cases in which the laminar and turbulent incompressible flow over a flat plate are calculated demonstrate the flow solver is capable of accurately capturing boundary-layer behaviour. Euler solutions from flow field calculations around two very different propeller geometries show a high level of accuracy and efficiency. Preliminary results from a viscous flow field calculation around a two-bladed propeller are very encouraging.

Increased Brain Histamine H3 Receptor Expression During Hibernation In Golden-Mantled Ground Squirrels, T Sallmen, Af Lozada, Ov Anichtchik, Al Beckman, P Panula Jan 2003

Increased Brain Histamine H3 Receptor Expression During Hibernation In Golden-Mantled Ground Squirrels, T Sallmen, Af Lozada, Ov Anichtchik, Al Beckman, P Panula

School of Biological and Marine Sciences

BACKGROUND: Hibernation is a state of extremely reduced physiological functions and a deep depression of CNS activity. We have previously shown that the histamine levels increase in the brain during hibernation, as does the ratio between histamine and its first metabolite, suggesting increased histamine turnover during this state. The inhibitory histamine H3 receptor has both auto- and heteroreceptor function, rendering it the most likely histamine receptor to be involved in regulating the activity of histamine as well as other neurotransmitters during hibernation. In view of accumulating evidence that there is a global depression of transcription and translation during hibernation, of …

Infra-Red Divergences In 2+1 Dimensional Gauge Theories, Zakaria Mazumder Jan 2003

Infra-Red Divergences In 2+1 Dimensional Gauge Theories, Zakaria Mazumder

School of Engineering, Computing and Mathematics Theses

Quantum field theories generally exhibit divergences. Ultra-violet divergences are treated through the renormalisation programme. Infra-red divergences, which accompany massless particles, are a characteristic of unbroken gauge theories and make it difficult to extract physical predictions. In this thesis we analyse various approaches to the infra-red problem and apply them to 2+1 dimensional gauge theories. These are useful as toy models, are related to the high temperature limit and are important in condensed matter physics. After briefly reviewing various responses to the infra-red problem in 3H-1 dimensions, we begin our study of gauge theories in 2+1 dimensions by performing a one …

Analytical Investigations In Magnetic Recording, Stephen J. C. Brown Jan 2003

Analytical Investigations In Magnetic Recording, Stephen J. C. Brown

School of Engineering, Computing and Mathematics Theses

The Fourier method is used to provide new analytic solutions for idealized mathematical models of double-element shielded magnetoresistive (MR) recording heads. The general two-dimensional model allows analysis of various recording head configurations; a single pole head, a ring head, a dual stripe head and a differential head. The analysis accommodates both longitudinal recording (with no soft magnetic underlayer present) and perpendicular recording (in the presence of a soft underlayer). Typical field, spectral response function and output voltage pulse plots for double-element MR heads are given and compared to published, approximate solutions. The integrals arising in the determination of the Fourier …

Formal Concept Matching And Reinforcement Learning In Adaptive Information Retrieval, Rohana Kithsiri Rajapakse Jan 2003

Formal Concept Matching And Reinforcement Learning In Adaptive Information Retrieval, Rohana Kithsiri Rajapakse

School of Engineering, Computing and Mathematics Theses

The superiority of the human brain in information retrieval (IR) tasks seems to come firstly from its ability to read and understand the concepts, ideas or meanings central to documents, in order to reason out the usefulness of documents to information needs, and secondly from its ability to learn from experience and be adaptive to the environment. In this work we attempt to incorporate these properties into the development of an IR model to improve document retrieval. We investigate the applicability of concept lattices, which are based on the theory of Formal Concept Analysis (FCA), to the representation of documents. …

A Correlation Framework For Continuous User Authentication Using Data Mining, Harjit Singh Jan 2003

A Correlation Framework For Continuous User Authentication Using Data Mining, Harjit Singh

School of Engineering, Computing and Mathematics Theses

The increasing security breaches revealed in recent surveys and security threats reported in the media reaffirms the lack of current security measures in IT systems. While most reported work in this area has focussed on enhancing the initial login stage in order to counteract against unauthorised access, there is still a problem detecting when an intruder has compromised the front line controls. This could pose a senous threat since any subsequent indicator of an intrusion in progress could be quite subtle and may remain hidden to the casual observer. Having passed the frontline controls and having the appropriate access privileges, …

Intelligent Vision-Based Navigation System, Kheng Lee Koay Jan 2003

Intelligent Vision-Based Navigation System, Kheng Lee Koay

School of Engineering, Computing and Mathematics Theses

This thesis presents a complete vision-based navigation system that can plan and follow an obstacle-avoiding path to a desired destination on the basis of an internal map updated with information gathered from its visual sensor. For vision-based self-localization, the system uses new floor-edges-specific filters for detecting floor edges and their pose, a new algorithm for determining the orientation of the robot, and a new procedure for selecting the initial positions in the self-localization procedure. Self-localization is based on matching visually detected features with those stored in a prior map. For planning, the system demonstrates for the first time a real-world …

Searching For Greater Variety In Strategic Thinking, Brendan O'Rourke, Martyn Pitt Jan 2003

Searching For Greater Variety In Strategic Thinking, Brendan O'Rourke, Martyn Pitt

Conference papers

This paper proposes a use of the discursive approach to explicate variety in ways of strategic thinking. Such an explication of variety is both useful managerially in increasing awareness of greater discursive resources and also theoretically in critiquing views of strategic thinking as homogenous and organizationally contained. Ways of strategic thinking have been investigated using a variety of approaches including expertise perspectives (Voss, Greene et al. 1983), cognitive mapping (Eden, Jones et al. (1979); Huff (1990) ) and upper echelon theory (Hambrick 1998). More recently the linguistic turn in organizational sciences (Alvesson and Kärreman 2000), and the study of strategy …

A Procedural Model For Integrating Physical And Cyberspaces In Architecture, Peter Anders Jan 2003

A Procedural Model For Integrating Physical And Cyberspaces In Architecture, Peter Anders

School of Engineering, Computing and Mathematics Theses

This dissertation articiilates opportunities offered by architectural computation, in particular the digital simulation of space known as virtual reality (VR) and its networked, social variant cyberspace. The thesis will argue that VR/cyberspace has exacerbated differences between architecture's materialist and idealist practices, widening the gap that separates them. In an effort to bridge this gap it presents a procedural model for how VR and cyberspace may be integrated within the practice and product of architecture. The dissertation presents important developments in architectural computation that disclose concepts and values that contrast with orthodox practice. Virtual reality and cyberspace, the foci of this …

Principles Of Metadesign : Processes And Levels Of Co-Creation In The New Design Space, Elisa Giaccardi Jan 2003

Principles Of Metadesign : Processes And Levels Of Co-Creation In The New Design Space, Elisa Giaccardi

School of Engineering, Computing and Mathematics Theses

In the tight of the material and cultural conditions of the present world and within the context of current design theories, this research aims to provide an understanding of Metadesign as emerging design cutture, and to integrate and advance its conceptual framework and principles through a tra nsdisci pli nary dialogue with the aesthetics and practice of Net Art. By rejecting the notion of Metadesign as an established design approach and practice, the creation of an etymological hypothesis based on the meanings of the prefix "-meta" (behind, together, between) becomes possible. Following this historical and cultural path, the research describes …
