The Formation of a Theory on Screenplay Imaging Through the Adaptation of Eisenstein's Principles of Montage

Description: The purpose and problem of this thesis is to formulate a theory on screenplay aesthetics with Eisenstein's montage as the mother theory providing the aesthetic nourishment for the proposed concept of imaging. The theory of screenplay imaging proposes that the screenplay is a montage of sub-narratives occurring in the sensual, emotional, and intellectual dimensions and expressing the grand narrative theme. It further suggests that the interaction between the screenplay and the reader-interpreter… more

Forms in the Chopin Ballades

Description: The term ballade is the French and German spelling of the English word "ballad" and the Italian ballata. Although each of these terms is derived from the Latin ballare, meaning "to dance," each denotes an entirely different meaning. The synonomous usage of these terms is definitely misleading (1,p. 67), Frederic Chopin, 1810-1849, was first to use this term as a title for piano compositions. The purpose of this study is to reveal the formal characteristics of each of the four ballades that Chop… more

Formulaic sequences in English conversation: Improving spoken fluency in non-native speakers.

Description: Native speakers often ignore the limitless potential of language and stick to institutionalized formulaic sequences. These sequences are stored and processed as wholes, rather than as the individual words and grammatical rules which make them up. Due to research on formulaic sequence in spoken language, English as a Second Language / Foreign Language pedagogy has begun to follow suit. There has been a call for a shift from the traditional focus on isolated grammar and vocabulary to formulaic s… more

The Formulation of a Theoretical Construct and the Development of an Instrument for the Evaluation of Curricula in Nursing

Description: The problem of this investigation was the development of a systematic method for the evaluation of curricula in baccalaureate nursing programs. The literature in nursing and general education was used to extrapolate theories and concepts for the formulation of a theoretical construct. This construct served as the basis for the evaluation instrument. The major concepts were identified as (1) underlying structure, (2) content of courses within the curriculum, and (3) methods and activities. Eleme… more

Fortification Renaissance: the Roman Origins of the Trace Italienne

Description: The Military Revolution thesis posited by Michael Roberts and expanded upon by Geoffrey Parker places the trace italienne style of fortification of the early modern period as something that is a novel creation, borne out of the minds of Renaissance geniuses. Research shows, however, that the key component of the trace italienne, the angled bastion, has its roots in Greek and Roman writing, and in extant constructions by Roman and Byzantine engineers. The angled bastion of the trace italienne … more

Forward Genetic Characterization of Medicago truncatula Tnt1 Insertion Mutants Defective in Nodule Development and Symbiotic Nitrogen Fixation

Description: Legumes are unique plants because they form special structures “nodules”, via symbiotic relationships with rhizobial bacteria present in the soil. Once rhizobia mature inside nodules, they fix atmospheric nitrogen providing a source of bioavailable nitrogen to the plant. To discover novel genetic components involved in the legume-rhizobia symbiosis by using forward genetic screening, we have isolated Medicago truncatula Tnt1 insertion mutants in the R108 ecotype, which are defective in nodule d… more

Foucault's Foundationless Democratic Theory

Description: I examine a key shift in Michel Foucault's political philosophy from a position in which he was a staunch anti-humanist, to a final position in which he advocated not only the ability of the subject to influence his political condition, but also the individual freedoms assured by a democratic form of government. I begin by summarizing his overall critique of the post-Enlightenment West, and then explain how his observation of the Iranian Revolution served as a key turning point concerning his a… more
