This qualitative study examines how five preservice teachers use multiple forms of representation (photography, spoken discourse, and written reflection) to interpret literacy. Eisner (1994) defines multiple forms of representations as "the devices that humans use to make public, conceptions that are privately held"(39). By better understanding preservice teachers' interpretations of literacy through multiple forms, teacher educators can promote a more holistic view of the literate qualities that define students as literate beings. Data included: individual and group interview transcripts, photographs, literacy autobiographies, literacy portfolios, journal entries, and other written reflections. Five collective themes emerged across the data: self and self esteem, literacy as a social act, the environment, and growth. From these themes creative inquiry, a framework for literacy inquiry evolved. Creative inquiry is a circular or spiral process of interpretation, hermeneutic in form, whereby interpretations return us to a new self. Although collective themes were revealed, the participants engaged with the multiple forms in undividual ways throughout the process of creative inquiry helping shape personal interpretations of literacy. / Ph.

This dissertation attempts to construct a theory which states that forms of enterprise are determined to a large extent by potential market failure. In the four independent, but closely interrelated chapters, I derive this hypothesis through theoretical reasoning, and suppose it by referring to empirical observations. Chapter 1, Forms of enterprise as a response to market failure, proposes the main idea that forms of enterprise are determined by market failure. I take three representative types of firms - capitalist firms, worker owned firms, and consumer cooperatives - and consider their relationship with three major causes for failure of markets: asymmetric information, externalities, and market power. Chapter 2, Firms owned by raw material suppliers: A case of food manufacturing firms run by agriculture cooperatives in Japan, is a case study which complements chapter 1. It deals with food processing farmers' cooperatives. These firms are owned by the suppliers of raw materials, and therefore classified as the fourth type of firms. I consider comparative efficiency of this type of firms from the viewpoint of market power and asymmetric information. Chapter 3, Asymmetric information on production-related risks and the form of enterprise: Capitalist firms versus consumer cooperatives, considers an efficient enterprise form when there is asymmetric information on accident risks in the market. Chapter 4, Market power and the form of enterprise: Capitalist firms, worker owned firms, or consumer cooperatives, considers an efficient enterprise form when there is market power in various markets. / Ph.

No / The advent of the Internet and e-commerce in the mid-to-late 20th century, has been instrumental in changing the landscape of the business environment. This has led to new management approaches and practices, mediated by advances in technology that are revolutionizing the workplace and continue to impact organizational structures and strategies. In this paper, we develop a taxonomy for IT and organizational theory from which we identify a pressing need for a conceptualisation of this rapid development in technology and its impact on organizational form. We introduce the concept of the e-environment to define the new and problem domain in which organizations are now operating as a consequence, particularly, of new technologies and the Internet. We explain how as the complexity of the technology increases, the ability to manage and appropriately exploit this e-environment under a traditional organizational form becomes more difficult. Currently, organizations are in the process of re-structuring to address this issue and facilitate continued strategic technological take-up to remain competitive. We posit the need for developing suitable organizational forms comprising both functional and technological specialists. We argue that the resulting forms are best explained by an extended model that can be seen as a composite of the existing forms. Finally, we present an executive reporting structure that will provide long-term top-level support for organizational decision making to manage the dynamic domain that is the e-environment.

This thesis consists of two parts. In the first part, we study stability properties of Hamiltonian systems on the Wasserstein space. Let H be a Hamiltonian satisfying conditions imposed in the work of Ambrosio and Gangbo. We regularize H via Moreau-Yosida approximation to get H[subscript Tau] and denote by μ[subscript Tau] a solution of system with the new Hamiltonian H[subscript Tau] . Suppose H[subscript Tau] converges to H as τ tends to zero. We show μ[subscript Tau] converges to μ and μ is a solution of a Hamiltonian system which is corresponding to the Hamiltonian H. At the end of first part, we give a sufficient condition for the uniqueness of Hamiltonian systems. In the second part, we develop a general theory of differential forms on the Wasserstein space. Our main result is to prove an analogue of Green's theorem for 1-forms and show that every closed 1-form on the Wasserstein space is exact. If the Wasserstein space were a manifold in the classical sense, this result wouldn't be worthy of mention. Hence, the first cohomology group, in the sense of de Rham, vanishes.
