Generative naming in Korean-English bilingual speakers and assessment tests for Korean-English bilingual speakers with aphasiaKwon, Hygine 16 September 2014 (has links)
This present study aimed to: 1) Update and expand the data pool of normal Korean-English speaker’s generative naming task from previous data in Food, Clothes, and Animal categories, 2) analyze the relationship between language proficiencies and total number of words and different categories, and 3) provide easier means of testing Korean-English bilinguals with aphasia through translated standardized tests such as Aphasia Language Performance Scale (ALPS) and Boston Naming Test (BNT). Five additional subjects were added to 25 participants from Kim (2010). The participants were asked to name as many different items as possible in 60 seconds in Food, Clothes, and Animal category in both English and Korean. The participants generated more items in Korean than in English. A significant negative correlation was observed between number of words generated in Korean and Korean proficiency and between number of category doublets produced and language proficiency difference scores. A significant positive correlation was observed between number of words generated in English and English proficiency. Large differences in the number of words generated were observed between the participants assessed and participants from Kim (2010), indicating education level and field of study impacts generative naming ability. / text

On the Rational Retraction IndexParadis, Philippe 26 July 2012 (has links)
If X is a simply connected CW complex, then it has a unique (up to isomorphism) minimal Sullivan model. There is an important rational homotopy invariant, called the rational Lusternik–Schnirelmann of X, denoted cat0(X), which has an algebraic formulation in terms of the minimal Sullivan model of X. We study another such numerical invariant called the rational retraction index of X, denoted r0(X), which is defined in terms of the minimal Sullivan model of X and satisfies 0 ≤ r0(X) ≤ cat0(X). It was introduced by Cuvilliez et al. as a tool to estimate the rational Lusternik–Schnirelmann category of the total space of a fibration. In this thesis we compute the rational retraction index on a range of rationally elliptic spaces, including for example spheres, complex projective space, the biquotient Sp(1) \ Sp(3) / Sp(1) × Sp(1), the homogeneous space Sp(3)/U(3) and products of these. In particular, we focus on formal spaces and formulate a conjecture to answer a question posed in the original article of Cuvilliez et al., “If X is formal, what invariant of the algebra H∗(X;Q) is r0(X)?”

Plan and Situated Action as a Function of Activity CategoryBahamdan, Walid January 2012 (has links)
Plans do not serve the particular circumstances of a given situation, but rather serve as abstract descriptions of some future activities. The relationship between plans, which are abstract, and actions, which are concrete, is referred to as the relationship between plans and situated actions. This relationship can be formulated in the following questions: 1) How do individuals conceive of future activities? 2) How does an individual who is acting upon a plan adjust when facing contingencies? The relationship between plans and situated actions has remained a source of intense academic discussions (e.g., Bardram, 1997; Bardram & Hensen, 2010; Leudar & Costall, 1996; Ng, 2002; Schmidt, 1997; Suchman, 1987). Despite the ample research on the relationship between plans and situated actions, a review of the literature indicates that the problem has not been adequately addressed (Randall et al., 2007; Suchman 2003), which has compelled this researcher to create a theoretical model that integrates the disparate nature of plans and line of actions.
Drawing on research on cognition and categorization theory, this thesis proposes a theoretical framework that conceptualizes the relationship between plans and situated actions in terms of activity categories. Specifically, the theoretical framework draws on the prototype and basic-level category theories of categorization, both of which were developed primarily by Rosch (1978), as well as the field theory developed by Lewin (1936). Categorization theories are used to address plans’ abstractness as they capture typifications of human experience. Field theory is used to address the concreteness of action as it captures dynamic properties of the situation in the here and now. The basic premise of the theoretical framework is that individuals conceive (have a knowledge) of plans and their attributes as future activity categories with a range of possibilities. These possibilities are structurally graded, ranging from highly typical to atypical. Plans are believed to be formed based on what is typical for the activity. The theoretical framework argues that an association exists between an individual’s knowledge of typical adjustment relevant to the activity and actual adjustment the individual makes while performing the activity. With this in mind, the theoretical framework considers the actor’s perspective to be central to the investigation. Based on the theoretical framework, several hypotheses are formularized and tested.
An in-depth case study conducted in a ready-mix concrete company was used to examine aspects of the theoretical framework empirically. The results of the case study provide a wide range of independent evidence supporting the framework. In addition, an experimental methodology was developed for quantitative testing in the laboratory aspects of the theoretical framework not attainable in the case study. Theoretical and practical implications of the proposed framework and empirical findings are examined. Future research directions are discussed.

Cross-Lingual Category Integration TechniqueTzeng, Guo-han 30 August 2006 (has links)
With the emergence of the Internet, many innovative and interesting applications from different countries have been stimulated and e-commerce is also getting more and more pervasive. Under this scenario, tremendous amount of information expressed in different languages are exchanged and shared by not only organizations but also individuals in the modern global environment. A large proportion of information is typically formatted and available as textual documents and managed by using categories. Consequently, the development of a practical and effective technique to deal with the problem of cross-lingual category integration (CLCI) becomes a very essential and important issue. Several category integration techniques have been proposed, but all of them deal with category integration involving only monolingual documents. In response, in this study, we combine the existing cross-lingual text categorization techniques with an existing monolingual category integration technique (specifically, Enhanced Naive Bayes) and proposed a CLCI solution to address cross-lingual category integration. Our empirical evaluation results show that our proposed CLCI technique demonstrates its feasibility and superior effectiveness.

Algebraic deformation of a monoidal categoryShrestha, Tej Bahadur January 1900 (has links)
Doctor of Philosophy / Department of Mathematics / David Yetter / This dissertation begins the development of the deformation theorem of monoidal categories which accounts for the function that all
arrow-valued operations, composition, the arrow part of the monoidal
product, and structural natural transformation are deformed.
The first chapter is review of algebra deformation theory. It includes the Hochschild complex of an algebra, Gerstenhaber's
deformation theory of rings and algebras, Yetter's deformation theory of a monoidal category, Gerstenhaber and Schack's bialgebra
deformation theory and Markl and Shnider's deformation theory for Drinfel'd algebras.
The second chapter examines deformations of a small $k$-linear
monoidal category. It examines deformations beginning with a naive computational approach to discover that as in Markl and Shnider's
theory for Drinfel'd algebras, deformations of monoidal categories are governed by the cohomology of a multicomplex. The standard
results concerning first order deformations are established. Obstructions are shown to be cocycles in the special case of strict
monoidal categories when one of composition or tensor or the associator is left undeformed.
At the end there is a brief conclusion with conjectures.
