The purpose of this study was to investigate the effectiveness of an experimental teaching method, Sport Aerobics, on the basketball skill acquisition of fifth grade students. This study investigated the differences in the shooting, dribbling, and passing scores of students taught with Sport Aerobics instruction compared to those taught with a traditional method, Practice Style. Sport Aerobics is an instructional method based on a theoretical framework developed by the researcher to enhance skill acquisition. This framework leads to teaching strategies such as using immediate feedback and specific cueing; arranging for students to engage in object free movement; arranging lessons, according to the framework's concept of movement progression, into lessons staged according to skill and sub-skill complexity; and instructing based on whole group organization. Sport Aerobic instructional strategies were designed to facilitate process learning that is recognized as important in today's development learning approach for age related curriculums. In contrast, the traditional Practice Style uses product-oriented strategies. ^ Four classrooms, consisting of seventy-nine fifth grade students from two physical education programs, at different locations, were randomly assigned to two treatments; Sport Aerobics and Practice Style for instruction over a 15 period curriculum. Using the American Alliance Physical Education Recreation & Dance tests, both groups were pretested and posttested for skill achievement of shooting, dribbling, and passing. Pretest and posttest skill score samples were collected and evaluated. ANCOVAs were performed on the posttests adjusted for the pretests to determine whether or not there would be greater achievement of skills with the Sport Aerobics method. Results failed to establish significant scoring differences between the two methods. Based on the literature and study findings a recommendation is made that longer lesson units will assist in the investigation of the effectiveness of both the instructional model and the individual elements that facilitate skill acquisition. ^

There is significant national evidence the language development of four year-olds is a critical area for later school success (Brooks-Gunn, Fuligni, & Berlin, 2003; Cunningham, & Stanovich, 1998). This study originated as part of Literacy Intervention X (LIX), a larger national study conducted to examine the effectiveness of early literacy curricula implemented in subsidized childcare centers. The professional development of childcare center providers is key to improving the quality of subsidized care. In exploring the mentoring practices of nine LIX literacy coaches, the researcher investigated the perceptions of what best mentoring practices facilitated the implementation of literacy curricula by childcare providers. A qualitative case study was conducted using a combination of participant observer notes, document analysis, and focus group semi-structured interviews. The researcher is a participant observer, one of the nine Literacy Coaches. The best mentoring practices from the perspective of the literacy coaches are related to building relationships including trust, mutual respect, support, empathy, and encouragement with the childcare providers, the center directors, and with fellow literacy coaches. Clear, constant, and consistent communication with the childcare providers was a vital mentoring practice in building a relationship between the literacy coach and childcare provider. Another best mentoring practice in building a relationship with the childcare provider was the perceptions of the literacy coaches as co-learners in the mentoring process. The best mentoring practices highlighted in this study exemplified the kind of effective professional development that builds on the strengths of the childcare providers and does not disrupt the childcare centers or the services provided by the subsidized childcare programs that meet the needs of children and families. The experience of these nine literacy coaches, including their perceptions of effective mentoring practices, along with lesson learned about relationships, mentoring team structures, and general project design sheds light on the challenge of mentoring subsidized childcare providers in future literacy intervention projects.

A concern for both educators and policy makers is how to increase the reading achievement of African American students. Studies have shown that rap music, which has its roots in the African American community, can be used as a tool to facilitate this increase, specifically how using rap songs in reading lessons can improve a child's reading motivation, information recall, and vocabulary development. There are also studies on how repeated reading of a text can help improve a child's reading fluency. Yet, there are no studies that combine rap music and repeated reading of a text. This study describes the effects of using a culturally responsive reading strategy on the fluency, decoding, and comprehension skills of African American students. ^ The sample consisted of 105 African American students within eight, second grade classrooms at two different elementary schools. The classes were randomly selected and assigned to the rap group or the control group. Students received eight half-hour sessions using either a rap text or a traditional text in a repeated reading lesson. All of the students were pre-tested and post-tested on the Oral Reading Fluency and the Nonsense Word Fluency portions of the Dynamic Indicators of Basic Literacy Skills Test. Additionally, a researcher constructed comprehension quiz was given to the students at the beginning, middle, and end of the study. Research questions were analyzed using ANOVAs and t tests. ^ The hypotheses were not supported but there was some evidence that rap music in a reading lesson helped improve the fluency skills of African American students at one of the schools. The results also revealed that rap music used in a reading lesson initially improved the comprehension skills of African American students. The rap treatment may not have worked best overall because of the lack of intensity of the treatment. ^ The study has shown some evidence to support using culturally appropriate materials such as rap with students. There needs to be more research on the interaction between teaching methods, materials, and students. ^

Fr. Marcelino García, S.J. has been the president of Belen Jesuit Preparatory School for 25 years. The longevity and success of his tenure is an exemplary case of effective leadership and provided significant insight into what constitutes effective school leadership. The target population for this case study consisted of the school’s 7 administrators, 90 faculty members, 10 English-speaking staff members, and 3 key informants. Data were collected using Bolman and Deal’s (1997) Leadership Orientation Survey along with the Jesuit Secondary Education Administration’s (1994) Administrative Leadership Profile Survey (ALPS). Data collected from the surveys were analyzed using the SPSS, version 10. The study also included data collected from focus interviews with Fr. García and six other significant members of the school community. The interviews were approximately 1-hour individual interviews that employed a semi-structured guide. A concurrent triangulation method was used that directly compared the results from these data collection methods. This was done by looking at the data as a whole and in parts. The parts were internal (faculty, administrators, and staff) and external (parents, alumni, and the superior of the Jesuit community) sectors. The comparison of the findings was then examined in terms of each research question. Analysis of the data revealed that while Fr. García’s predominant leadership style reflected the typical Bolman and Deal characteristics associated with the political frame, his leadership demonstrates access to all four frames. Research has found a correlation between multiple frame use and successful leadership. Relatedly, Fr. García’s capacity to approach his administration from various perspectives is indicative of success. In addition, from the perspective of Jesuit education, an analysis of Fr. García’s leadership indicated recurring themes that contributed to the school’s organizational health. The results of this study provide an extensive analysis of the administration of a unique leader. An analysis of Fr. García’s leadership style from two perspectives gives fresh insight into sustained and successful leadership.

In their dialogue - An Analysis of Stock Market Performance: The Dow Jones Industrial Average and the Three Top Performing Lodging Firms 1982 – 1988 - by N. H. Ringstrom, Professor and Elisa S. Moncarz, Associate Professor, School of Hospitality Management at Florida International University, Professors Ringstrom and Moncarz state at the outset: “An interesting comparison can be made between the Dow Jones lndustrial Average and the three top performing, publicly held lodging firms which had $100 million or more in annual lodging revenues. The authors provide that analytical comparison with Prime Motor Inns Inc., the Marriott Corporation, and Hilton Hotels Corporation.” “Based on a criterion of size, only those with $100 million in annual lodging revenues or more resulted in the inclusion of the following six major hotel firms: Prime Motor Inns, Inc., Marriott Corporation, Hilton Hotels Corporation, Ramada Inc., Holiday Corporation and La Quinta Motor Inns, Inc.,” say Professors Ringstrom and Moncarz in framing this discussion with its underpinnings in the years 1982 to 1988. The article looks at each company’s fiscal and Dow Jones performance for the years in question, and presents a detailed analysis of said performance. Graphic analysis is included. It helps to have a fairly vigorous knowledge of stock market and fiscal examination criteria to digest this material. The Ringstrom and Moncarz analysis of Prime Motor Inns Incorporated occupies the first 7 pages of this article in and of itself. Marriot Corporation also occupies a prominent position in this discussion. “Marriott, a giant in the hospitality industry, is huge and continuing to grow. Its 1987 sales were more than $6.5 billion, and its employees numbered over 200,000 individuals, which place Marriott among the 10 largest private employers in the country,” Ringstrom and Moncarz parse Marriott’s influence as a significant financial player. “The firm has a fantastic history of growth over the past 60 years, starting in May 1927 with a nine-seat A & W Root Beer stand in Washington, D.C.,” offer the authors in initialing Marriot’s portion of the discussion with a brief history lesson. The Marriot firm was officially incorporated as Hot Shoppes Inc. in 1929. As the thesis statement for the discussion suggests the performance of these huge, hospitality giants is compared and contrasted directly to the Dow Jones Industrial Average performance. Reasons and empirical data are offered by the authors to explain the distinctions. It would be difficult to explain those distinctions without delving deeply into corporate financial history and the authors willingly do so in an effort to help you understand the growth, as well as some of the setbacks of these hospitality based juggernauts. Ringstrom and Moncarz conclude the article with an extensive overview and analysis of the Hilton Hotels Corporation performance for the period outlined. It may well be the most fiscally dynamic of the firms presented for your perusal. “It is interesting to note that Hilton Hotels Corporation maintained a very strong financial position with relatively little debt during the years 1982-1988…the highest among all companies in the study,” the authors paint.

The purpose of this study was to compare the effects of three student response conditions during computer-assisted instruction on the acquisition and maintenance of social-studies facts. Two of the conditions required active student responding (ASR), whereas the other required an on-task (OT) response. Participants were five fifth-grade students, with learning disabilities enrolled in a private school. An alternating treatments design with a best treatments phase was used to compare the effects of the response procedures on three major dependent measures: same-day tests, next-day tests, and maintenance tests. ^ Each week for six weeks, participants were provided daily one-to-one instruction on sets of 21 unknown social-studies facts using a hypermedia computer program, with a new set of facts being practiced each week. Each set of 21 facts was divided randomly into three conditions: Clicking-ASR, Repeating-ASR, and Listening-OT. Hypermedia lesson began weekly with the concept introduction lesson, followed by practice and testing. Practice and testing occurred four days per week, per set. During Clicking-ASR, student practice involved the selection of a social-studies response by clicking on an item with the mouse on the hypermedia card. Repeating-ASR instruction required students to orally repeat the social-studies facts when prompted by the computer. During Listening-OT, students listened to the social-studies facts being read by the computer. During weeks seven and eight, instruction occurred with seven unknown facts using only the best treatment. ^ Test results show that all for all 5 students, the Repeating-ASR practice procedure resulted in more social-studies facts stated correctly on same-day tests, next-day tests, and one-and two-week maintenance tests. Clicking-ASR was the next most effective procedure. During the seventh and eighth week of instruction when only the best practice condition was implemented, Repeating-ASR produced higher scores than all conditions (including Repeating-ASR) during the first six weeks of the study. ^ The results lend further support to the growing body of literature that demonstrates the positive relation between ASR and student achievement. Much of the ASR literature has focused on the effects of increased ASR during teacher-led or peer-mediated instruction. This study adds a dimension to that research in that it demonstrated the importance of ASR during computer-assisted instruction and further suggests that the type of ASR used during computer-assisted instruction may influence learning. Future research is needed to investigate the effectiveness of other types of ASR during computer-assisted instruction and to identify other fundamental characteristics of an effective computer-assisted instruction. ^

Colombia's increasingly effective efforts to mitigate the power of the FARC and other illegitimately armed groups in the country can offer important lessons for the Peruvian government as it strives to prevent a resurgence of Sendero Luminoso and other illegal non-state actors. Both countries share certain particular challenges: deep economic, social, and in the case of Peru ethnic divisions, the presence of and/or the effects of violent insurgencies, a large-scale narcotics production and trafficking, and a history of weak state presence in large tracts of isolated and scarcely-populated areas. Important differences exist, however in the nature of the insurgencies in the two countries, the government response to them and the nature of government and society that affects the applicability of Colombia's experience to Peru. The security threat to Panama from drug trafficking and Colombian insurgents --often a linked phenomenon-- are in many ways different from the drug/insurgent factor in Colombia itself and in Peru, although there are similar variables. Unlike the Colombian and Peruvian cases, the security threat in Panama is not directed against the state, there are no domestic elements seeking to overthrow the government -- as the case of the FARC and Sendero Luminoso, security problems have not spilled over from rural to urban areas in Panama, and there is no ideological component at play in driving the threat. Nor is drug cultivation a major factor in Panama as it is in Colombia and Peru. The key variable that is shared among all three cases is the threat of extra-state actors controlling remote rural areas or small towns where state presence is minimal. The central lesson learned from Colombia is the need to define and then address the key problem of a "sovereignity gap," lack of legitimate state presence in many part of the country. Colombia's success in broadening the presence of the national government between 2002 and the presence is owed to many factors, including an effective national strategy, improvements in the armed forces and police, political will on the part of government for a sustained effort, citizen buy-in to the national strategy, including the resolve of the elite to pay more in taxes to bring change about, and the adoption of a sequenced approach to consolidated development in conflicted areas. Control of territory and effective state presence improved citizen security, strengthened confidence in democracy and the legitimate state, promoted economic development, and helped mitigate the effect of illegal drugs. Peru can benefit from the Colombian experience especially in terms of the importance of legitimate state authority, improved institutions, gaining the support of local citizens, and furthering development to wean communities away from drugs. State coordinated "integration" efforts in Peru as practiced in Colombia have the potential for success if properly calibrated to Peruvian reality, coordinated within government, and provided with sufficient resources. Peru's traditionally weak political institutions and lack of public confidence in the state in many areas of the country must be overcome if this effort is to be successful.

Poor informational reading and writing skills in early grades and the need to provide students more experience with informational text have been identified by research as areas of concern. Wilkinson and Son (2011) support future research in dialogic approaches to investigate the impact dialogic teaching has on comprehension. This study (N = 39) examined the gains in reading comprehension, science achievement, and metacognitive functioning of individual second grade students interacting with instructors using dialogue journals alongside their textbook. The 38 week study consisted of two instructional phases, and three assessment points. After a period of oral metacognitive strategies, one class formed the treatment group (n=17), consisting of two teachers following the co-teaching method, and two classes formed the comparison group ( n=22). The dialogue journal intervention for the treatment group embraced the transactional theory of instruction through the use of dialogic interaction between teachers and students. Students took notes on the assigned lesson after an oral discussion. Teachers responded to students' entries with scaffolding using reading strategies (prior knowledge, skim, slow down, mental integration, and diagrams) modeled after Schraw's (1998) strategy evaluation matrix, to enhance students' comprehension. The comparison group utilized text-based, teacher-led whole group discussion. Data were collected using different measures: (a) Florida Assessments for Instruction in Reading (FAIR) Broad Diagnostic Inventory; (b) Scott Foresman end of chapter tests; (c) Metacomprehension Strategy Index (Schmitt, 1990); and (d) researcher-made metacognitive scaffolding rubric. Statistical analyses were performed using paired sample t-tests, regression analysis of covariance, and two way analysis of covariance. Findings from the study revealed that experimental participants performed significantly better on the linear combination of reading comprehension, science achievement, and metacognitive function, than their comparison group counterparts while controlling for pretest scores. Overall, results from the study established that teacher scaffolding using metacognitive strategies can potentially develop students' reading comprehension, science achievement, and metacognitive awareness. This suggests that early childhood students gain from the integration of reading and writing when using authentic materials (science textbooks) in science classrooms. A replication of this study with more students across more schools, and different grade levels would improve the generalizability of these results.

In line with Wittgenstein's axiom that "what the solipsist means is quite correct; only it cannot be said, but makes itself manifest," this thesis aims to demonstrate how the gulf between analytic and continental philosophy can best be bridged through the mediation of art. The present thesis brings attention to Markson's work, lauded in the tradition of Faulkner, Joyce, and Lowry, as exemplary of the shift from modernity to postmodernity, wherein the human heart is not only in conflict with itself, but with the language out of which it is necessarily constituted. Markson limns the paradoxical condition of the subject severed from intersubjectivity, and affected not only by the grief of bereavement, which can be defined in Heideggarian terms as anxiety for the ontic negation of a being (i.e., death), but by loss, which I assert is the ontological ground for how Dasein encounters the nothing in anxiety proper.

Students with specific learning disabilities (SLD) typically learn less history content than their peers without disabilities and show fewer learning gains. Even when they are provided with the same instructional strategies, many students with SLD struggle to grasp complex historical concepts and content area vocabulary. Many strategies involving technology have been used in the past to enhance learning for students with SLD in history classrooms. However, very few studies have explored the effectiveness of emerging mobile technology in K-12 history classrooms. This study investigated the effects of mobile devices (iPads) as an active student response (ASR) system on the acquisition of U.S. history content of middle school students with SLD. An alternating treatments single subject design was used to compare the effects of two interventions. There were two conditions and a series of pretest probesin this study. The conditions were: (a) direct instruction and studying from handwritten notes using the interactive notebook strategy and (b) direct instruction and studying using the Quizlet App on the iPad. There were three dependent variables in this study: (a) percent correct on tests, (b) rate of correct responses per minute, and (c) rate of errors per minute. A comparative analysis suggested that both interventions (studying from interactive notes and studying using Quizlet on the iPad) had varying degrees of effectiveness in increasing the learning gains of students with SLD. In most cases, both interventions were equally effective. During both interventions, all of the participants increased their percentage correct and increased their rate of correct responses. Most of the participants decreased their rate of errors. The results of this study suggest that teachers of students with SLD should consider a post lesson review in the form of mobile devices as an ASR system or studying from handwritten notes paired with existing evidence-based practices to facilitate students’ knowledge in U.S. history. Future research should focus on the use of other interactive applications on various mobile operating platforms, on other social studies subjects, and should explore various testing formats such as oral question-answer and multiple choice.

This study investigated the use of music listening maps to help learning and the preferences of second graders for orchestral music. Subjects were a population of four 2nd grade classes, and were randomly divided into two groups. The investigation was a counterbalanced, post-test only design, lasting for three consecutive classes. Two treatments/lessons were presented and a third lesson was a review. In Treatment 1 Group I used listening maps first, while Group II received instruction without listening maps. In Treatment 2, the order was reversed. Two post-tests and a comprehensive test were administered. An affective survey was administered after the treatments, measuring student preference and attitude. When listening maps were presented, scores were significantly higher. It did not matter whether the listening maps were presented first or not. Results of the survey show student preference will increase with music listening maps.

Science application has faced problems in the process of training and cognizant thinking subjects in their actions. Thus, this work is justified in order to reorganize the contents of this area of knowledge. Thus, the research entitled "Plantation School: generating themes and teaching moments in teaching of science" was developed with a group of 6th grade of elementary school, from the planting of vegetables in tires without usefulness, with purpose of building meanings and scientific concepts to students. This work was based on sociointeractionist perspective of Vygotsky (1996, 1998), education for thematic research Freire (1983, 1996) as well as in problem-solving situations identified by the methodology of Pedagogical Moments Delizoicov and Angoti (1992; 2002 ) which together corroborated for the construction of a proposed teaching and learning, curriculum reorganization and significance of scientific concepts. Thus, the project breaks in practice with the linearity of the contents, to develop and analyze themes mediated by pedagogical moments, in order to ascertain the contribution of this methodological resource for the teacher's work, with regard to the understanding of scientific concepts by students. Thus, lesson plans were built based on the study situation "Horta School" and Themes Generators "human interaction with the environment", "photosynthesis", "Ecology and Nutrition of living beings", culminating in the work proposal developed in the classroom. From these themes, the contents were worked through pedagogical moments, which are organized into three stages: questioning, organization / systematization of knowledge and application / contextualization of knowledge. Thus, within each Theme Generator activities were planned which resulted in the involvement of students in learning scientific concepts, such as the issue of sustainability, environmental pollution, nutrition of living beings and the decomposition of organic matter. This work led and motivated student participation in Themes generators, and allows greater interaction between teacher-student and student among his peers, through dialogism established in the classroom, which promoted a more meaningful learning for students.

*Designated as an exemplary master's project for 2015-16*
The American approach to disparities in educational achievement is deficit focused and based on false assumptions of equal educational opportunity and social mobility. The labels attached to children served by compensatory early childhood education programs have evolved, e.g., from “culturally deprived” into “at-risk” for school failure, yet remain rooted in deficit discourses and ideology. Drawing on multiple bodies of literature, this thesis analyzes the rhetoric of compensatory education as viewed through the conceptual lens of the deficit thinking paradigm, in which school failure is attributed to perceived genetic, cultural, or environmental deficiencies, rather than institutional and societal inequalities. With a focus on the evolution of deficit thinking, the thesis begins with late 19th century U.S. early childhood education as it set the stage for more than a century of compensatory education responses to the needs of children, inadequacies of immigrant and minority families, and threats to national security. Key educational research and publications on genetic-, cultural-, and environmental-deficits are aligned with trends in achievement gaps and compensatory education initiatives, beginning mid-20th century following the Brown vs Board declaration of 1954 and continuing to the present. This analysis then highlights patterns in the oppression, segregation, and disenfranchisement experienced by low-income and minority students, largely ignored within the mainstream compensatory education discourse. This thesis concludes with a heterodox analysis of how the deficit thinking paradigm is dependent on assumptions of equal educational opportunity and social mobility, which helps perpetuate the cycle of school failure amid larger social injustices.

Integrating information from multiple sources is a crucial function of the brain. Examples of such integration include multiple stimuli of different modalties, such as visual and auditory, multiple stimuli of the same modality, such as auditory and auditory, and integrating stimuli from the sensory organs (i.e. ears) with stimuli delivered from brain-machine interfaces.
The overall aim of this body of work is to empirically examine stimulus integration in these three domains to inform our broader understanding of how and when the brain combines information from multiple sources.
First, I examine visually-guided auditory, a problem with implications for the general problem in learning of how the brain determines what lesson to learn (and what lessons not to learn). For example, sound localization is a behavior that is partially learned with the aid of vision. This process requires correctly matching a visual location to that of a sound. This is an intrinsically circular problem when sound location is itself uncertain and the visual scene is rife with possible visual matches. Here, we develop a simple paradigm using visual guidance of sound localization to gain insight into how the brain confronts this type of circularity. We tested two competing hypotheses. 1: The brain guides sound location learning based on the synchrony or simultaneity of auditory-visual stimuli, potentially involving a Hebbian associative mechanism. 2: The brain uses a ‘guess and check’ heuristic in which visual feedback that is obtained after an eye movement to a sound alters future performance, perhaps by recruiting the brain’s reward-related circuitry. We assessed the effects of exposure to visual stimuli spatially mismatched from sounds on performance of an interleaved auditory-only saccade task. We found that when humans and monkeys were provided the visual stimulus asynchronously with the sound but as feedback to an auditory-guided saccade, they shifted their subsequent auditory-only performance toward the direction of the visual cue by 1.3-1.7 degrees, or 22-28% of the original 6 degree visual-auditory mismatch. In contrast when the visual stimulus was presented synchronously with the sound but extinguished too quickly to provide this feedback, there was little change in subsequent auditory-only performance. Our results suggest that the outcome of our own actions is vital to localizing sounds correctly. Contrary to previous expectations, visual calibration of auditory space does not appear to require visual-auditory associations based on synchrony/simultaneity.
My next line of research examines how electrical stimulation of the inferior colliculus influences perception of sounds in a nonhuman primate. The central nucleus of the inferior colliculus is the major ascending relay of auditory information before it reaches the forebrain, and thus an ideal target for understanding low-level information processing prior to the forebrain, as almost all auditory signals pass through the central nucleus of the inferior colliculus before reaching the forebrain. Thus, the inferior colliculus is the ideal structure to examine to understand the format of the inputs into the forebrain and, by extension, the processing of auditory scenes that occurs in the brainstem. Therefore, the inferior colliculus was an attractive target for understanding stimulus integration in the ascending auditory pathway.
Moreover, understanding the relationship between the auditory selectivity of neurons and their contribution to perception is critical to the design of effective auditory brain prosthetics. These prosthetics seek to mimic natural activity patterns to achieve desired perceptual outcomes. We measured the contribution of inferior colliculus (IC) sites to perception using combined recording and electrical stimulation. Monkeys performed a frequency-based discrimination task, reporting whether a probe sound was higher or lower in frequency than a reference sound. Stimulation pulses were paired with the probe sound on 50% of trials (0.5-80 µA, 100-300 Hz, n=172 IC locations in 3 rhesus monkeys). Electrical stimulation tended to bias the animals’ judgments in a fashion that was coarsely but significantly correlated with the best frequency of the stimulation site in comparison to the reference frequency employed in the task. Although there was considerable variability in the effects of stimulation (including impairments in performance and shifts in performance away from the direction predicted based on the site’s response properties), the results indicate that stimulation of the IC can evoke percepts correlated with the frequency tuning properties of the IC. Consistent with the implications of recent human studies, the main avenue for improvement for the auditory midbrain implant suggested by our findings is to increase the number and spatial extent of electrodes, to increase the size of the region that can be electrically activated and provide a greater range of evoked percepts.
My next line of research employs a frequency-tagging approach to examine the extent to which multiple sound sources are combined (or segregated) in the nonhuman primate inferior colliculus. In the single-sound case, most inferior colliculus neurons respond and entrain to sounds in a very broad region of space, and many are entirely spatially insensitive, so it is unknown how the neurons will respond to a situation with more than one sound. I use multiple AM stimuli of different frequencies, which the inferior colliculus represents using a spike timing code. This allows me to measure spike timing in the inferior colliculus to determine which sound source is responsible for neural activity in an auditory scene containing multiple sounds. Using this approach, I find that the same neurons that are tuned to broad regions of space in the single sound condition become dramatically more selective in the dual sound condition, preferentially entraining spikes to stimuli from a smaller region of space. I will examine the possibility that there may be a conceptual linkage between this finding and the finding of receptive field shifts in the visual system.
In chapter 5, I will comment on these findings more generally, compare them to existing theoretical models, and discuss what these results tell us about processing in the central nervous system in a multi-stimulus situation. My results suggest that the brain is flexible in its processing and can adapt its integration schema to fit the available cues and the demands of the task.

This dissertation attempts to retrieve the integration of prayer and theology in the life of the church. Prayer is a spiritual and bodily theological activity that forms Christian identity and virtuous character. The bodily dimension of Christian prayer plays an essential role in theological understanding and moral formation. However, the embodiment of prayer has been mostly neglected in modern academic theology. This study highlights the significance of the body at prayer in theological studies and spiritual formation.
Chapter 1 presents Karl Barth’s theology of prayer as a model of the integration of prayer, theology, and Christian life (lex orandi, lex credendi, lex agendi). However, Barth’s attempt to overcome the dichotomy between theory and practice in theology did not pay much attention to embodiment of prayer. Through ritual studies and phenomenology (Marcel Mauss, Maurice Merleau-Ponty, and Pierre Bourdieu), chapter 2 shows why the bodily dimension of the practice of prayer should be recovered in theology and ministry; then it explains how Christians in the early and medieval church actually prayed with the body, how their bodily actions were understood in their theological paradigms, and how their actions contributed to the formation of Christian character. Chapter 3 narrows the focus to the formation of the heart in the making of Christian character. The practice of prayer has been emphasized not only as an expression of the inner heart of pray-ers but also as a channel of grace that shapes their affections as enduring dispositions of the heart. Furthermore, historically the bodily practice of prayer gave theological authority to the devout Christians who were marginalized in academic theology or ecclesiastical hierarchy, and Chapter 4 presents the lex orandi of praying women who gained their theological knowledge, wisdom, and authority through their exemplary practices of prayer (Catherine of Siena, Mechthild of Magdeburg, Julian of Norwich, Margery Kempe, and Teresa of Avila). These historical examples reveal how Christian communities appreciated and celebrated the theological voices from the margins, which developed from theological embodiments in prayer.
This dissertation concludes that academic theology needs to heed these diverse theological voices, which are nurtured through everyday practice, as an integral part of theological studies. Therefore, it calls for a new paradigm for understanding the relationship between theory and practice in theological education. The integration between theory and bodily practice is necessary for both academic theology and spiritual formation. A more holistic understanding of Christian practices will not only enhance the training of scholars and clergy but also give the laity their own theological voices that will enrich academic theology.
