The current research examined whether nonword repetition (NWR) tasks, designed to measure phonological short-term memory, are also influenced by familiarity with lexical representation of a given language. In Study 1, children with and without exposure to Hebrew were administered a NWR task based on the Hebrew language structure (HNWR). On the HNWR, participants with Hebrew exposure significantly outperformed participants who had no familiarity with any Semitic language. This indicates that long-term phonological and lexical knowledge can be used to aid NWR performance. Study 2 investigated whether a NWR task based on a foreign language could minimize the lexicality effect. English speaking undergraduate students rated the less familiar HNWR task to be lower in wordlikeness than English-like NWR tasks. These findings demonstrate that regardless of language background a NWR task based on an unfamiliar language structure is a more valid measure of the phonological processing skills required for vocabulary acquisition.

The purpose of this study is to investigate the most common phonetic and phonological difficulties in the teaching of Spanish as a foreign language. The study has been based on the following questions: Which difficulties can teachers encounter when teaching phonetics and phonology? Which difficulties can students encounter when learning phonetics and phonology? How is phonetics and phonology taught? In order to be able to investigate the difficulties, a questionnaire has been handed out to five experienced teachers. The results of the questionnaires, together with the theory, has been analysed in the analysis. The outcome of the analysis shows that several difficulties can be detected in both the teaching and in the learning process. The results of the questionnaires also show us that the teachers mostly teach phonetics the same way: through repetition and imitation, the conductive method, and very few think outside of the box to encounter new methods.

A helicopter based system equipped with a millimetre-wave fire control radar is studied for improvement of the detection probability for moving ground targets. The system is a pulse doppler radar that sends out the electromagnetic wave in repetitive pulses. The frequency in which radar sends this pulse is called Pulse Repetition Frequency (PRF). The velocity of the moving targets is measured by spectral analysis of the pulses received. With this sort of system some targets will not be possible to detect. These targets are said to be blind for the radar. Also the measured targets can be ambiguous. A solution to this is to shift PRF during the time the radar emits itspulses on the target. This method is called PRF block staggering. The antenna is mounted on a mechanical sweep on top of the rotor of the helicopter. Because of this the time on target is limited. This means that the measured velocity resolution of the radar is also limited. With the studied method it is possible to resolve range and velocity ambiguities. This is under the condition that it is acceptable with a reduction in the velocity resolution by a factor equal to the number of PRF blocks used. The work leading to this thesis included developing a program in Mathworks Matlab for studying different configurations of PRFs and the effect on the detection probability.

"Passage" presents a negotiation between the natural and the human-made realms and comments on the duality of perceptions and emotional responses associated with each. On the one hand, I aim to create a calm, quiet and peaceful environment offering a pleasant and meditative experience.  On the other hand, I offer the challenge of contemplation in a city-like space that evokes dense urban architecture in the process of decay. Both experiences draw on my personal histories of fact and fiction, reality and dream, hopefully resulting in evocative parallel experiences for those who encounter my exhibition space.

J.O. Mallander’s Extended Play (1968) is a sound recording, a readymade, of the counting of votes in two presidential elections in Finland, during 1962 and 1968. A voice repeats monotonously: “Kekkonen, Kekkonen, Kekkonen, Kekkonen, Kekkonen…” Although the Finnish president Urho Kekkonen represents, almost personifies, the politics of the post World War II period in Finland, Extended Play does not explicitly address the political. Rather, as this essay argues, it engages in the discourses of power and politics by providing a temporalization of its fixedness, or what Jacques Derrida terms the proper. Extended Play is, in parallel with Derrida’s critique of western metaphysics, a deconstruction in sound that challenges the state ideologies conveyed in the process of the counting of votes, where the presuppositions of the presence of the voice characterizes the ambiguities of power that Kekkonen’s politics of neutrality represent. Mallander’s readymade emerges as a double of the game theory strategies of the Cold War, a mimetic surplus of the administrative control mechanisms of sound recording. Through overturning the dialectics of the original and the copy, where repetition of sound also temporalizes the representation of the proper, it does not unequivocally reproduce its content. As an aural document, repeated and mass-produced as a record, it devalues, therefore, presumptions of origin. Derrida’s idea of “sous rature” initiates, in the discussion of Extended Play as a specific form of conceptual sound art, the notion of sound under erasure, which is not reducible to an auditory or medium-specific practice.

The main objective of this master&rsquo / s thesis is to examine the concept of difference according to French philosophers Gilles Deleuze and Henri Bergson. In order to explicate this crucial concept and its emphasis in these thinkers&rsquo / philosophies, this dissertation is focused on the notion of time and memory. Through the thesis, first Deleuze&rsquo / s critical attitude towards representational and dialectical approachs for difference is elucidated. After the comprehensive examination for the meaning of difference according to Deleuze, the understanding of time is revealed by means of Deleuzian comprehension of repetition and Bergsonian notion of duration. Throughout the thesis what is virtually hidden beneath the arguments, what is common in both philosophers finally is exposed as the concept of becoming. For Deleuze, whose philosophy of time is certainly dependent on Bergson, time creates a renewed conception in order for subject to be an individual as the state of permanent becoming. And an individual which is qualified as a state of becoming, is the memory of time where the latter is an infinite virtuality.

The aim of this study was to investigate the effects web-based multimedia annotated vocabulary learning in context model and in spaced repetitions on vocabulary retention of intermediate level English language learners. The research study encompassed two main faces which was related to development of the material and implementation of it. In WEBVOCLE, which stands for web-based vocabulary learning material, the contextual presentation of vocabulary were enriched with audible online dictionary, pictures and animations / target words were repeated by the learners with interactive exercises, such as gap-filling, cloze and multiple choice test, games, puzzles, in &lsquo / spaced repetitions&rsquo / . In the study both qualitative and quantitative data were gathered through attitude questionnaires, checklists, interviews, focus group interviews and through vocabulary retention tests. The qualitative data were analyzed according to qualitative data analysis techniques and quantitative data were analyzed using SPSS statistics software. Feedback obtained from the learners demonstrated that they not only developed a positive attitude toward English vocabulary language learning but also increased their vocabulary retention level of the target vocabulary through spaced repetitions.

The Student Success Initiative (SSI) established, in 1999, various promotional gates for students to pass the state-mandated high-stakes assessment test known as the Texas Assessment of Knowledge & Skills (TAKS), administered in the areas of reading for third graders and of reading and math for fifth graders. Largely perceived as antisocial promotion legislation, outcomes of the SSI implementation did not seem to coincide with their original intentions. To ascertain the veracity of this claim, interviews were scheduled with a variety of local level stakeholders serving as decision-making participants in a structure known as the grade placement committee. Grade placement committee members address student promotion and retention decisions when students do not meet the passing standards for the TAKS tests. Because the SSI is still recent in its implementation, to date there is not a wide body of research examining the stakeholder perceptions of the SSI and of their role in the decision-making process for student retention and promotion. To this end, several interviews were conducted with teachers, with parents, and with campus or district-level administrators. The interviews served to gauge the stakeholder perceptions regarding their role in the grade placement committee itself as decision-makers and also their perceptions or their experiences regarding how often or likely students are to be promoted or to be retained in the context of the grade placement committee meetings. The participants also spoke about their views regarding the effectiveness of the SSI and the outcomes of its implementation. The research participants spoke to their personal experiences with student retention and promotion. The stakeholders' views range from the perception that the SSI puts students at risk of failure, actually causing students to be promoted more often to the opinion that the SSI does hold both the teacher and the parents more accountable for student success. Several broad themes emerged from the data. The themes of perceived power, underlying or unwritten agendas and a call for change due to dissatisfaction with the current system were evident upon the examination of the data.

This study examined which predictor measures best explain first grade retention in Texas, using three campus configuration types. Predictor measures were chosen from Texas public school campus student demographic and operational data, as well as community-based early childhood program data. Prior to this study, no research had been conducted in Texas that merged public school-based early childhood program data with community-based early childhood program data in order to understand a historical and often neglected problem in the state's education system: the number of students being held back in first grade. To determine which predictor measures best explained first grade retention among selected campus configuration types, a hierarchical regression analysis was conducted. Initially, public school campuses that did not contain early childhood and/or pre- kindergarten programs in their campus configuration, and that generally served students with fewer risks for academic and social failure, had lower first grade retention rates, which were statistically significant. After controlling for multiple campus student demographic and operational predictor measures, as well as access to community-based early childhood programs per first grade student, however, campuses that contained early childhood and pre-kindergarten programs, or a combination of both, had retention rates that were no longer statistically different from the campus configurations that, on average, contained fewer economically disadvantaged and at-risk students. Although the study was a systems-level analysis and was restricted to making inferences at the aggregate level that were non-causal, the findings provided several clues that suggest early childhood programs and experiences, both internal and external to public school campuses, have the potential to affect the short- and long-term academic success of vulnerable children. The study encouraged collaboration between the public school system and a complex, diverse community-based early childhood system, using a "vulnerable neighborhood approach" (Bruner,2007), as one effective strategy for promoting school readiness and success for disadvantaged children, and as one means to address this challenge. / text
