Transcultural experiences: A literature bridge to English for ESOL students from Cuba

This qualitative study is concerned with exploring the transcultural experiences of ESOL students and connecting their lived experiences to literature in the classroom. The purpose of this study was to describe and explain the transcultural perspectives of six high school and community college students: four Cuban born students and two American born/raised students of Cuban-American culture. The participants were from Barbara Goleman Senior High School and Miami-Dade Community College. The six phenomenological portraits were explored in the form of lived experience pieces, representing the students' transcultural experiences. The data was collected in the form of student interviews, researcher's journal, and document reviews. The following exploratory questions guided this study: (1) From the perspective of four Cuban-born, non-native English-speaking students (NNS), what are the essential structures of their transcultural identities? (2) What are the underlying themes that account for the Cuban NNS students' transcultural experiences? (3) What are the universal transcultural structures among the Cuban NNS students' transcultural experiences and the Cuban-American, native English/Spanish speaking (NESS) students' experiences? (4) What are the possible structural meanings of the Cuban NNS students' interests in relation to their transcultural experiences? (5) What are some connections between the structural themes inherent in the Cuban NNS students' transcultural experiences and teaching literature in ESOL? ^ A phenomenological approach was used to investigate the participants' transcultural experiences, focused on the students' lived experiences. The study consisted of three interview sessions for each of the six participants. The analysis of the data was conducted following the principles of qualitative research, which included participant interviews, thematic analysis, researcher's journal, document reviews, and triangulation. The researcher created portraits representing students' transcultural experiences. Subsequently, the participants' transcultural experiences were used to respond to the exploratory questions, including comparing and contrasting themes and drawing connections among teaching literature in the ESOL classroom. ^ The results of this study show some relevant specific statements and themes that emerged from the students' transcultural data. The results serve as a better understanding of these students' transcultural experiences and the potentiality of connecting their perspectives to literature in the classroom. In addition, this study shows the need for a better understanding of the connection between transcultural experiences and literature in ESOL. ^

What secondary English to speakers of other languages (ESOL) teachers know about social and academic language and instructional strategies for limited English proficient students

The purpose of this study was to examine what secondary English to Speakers of Other Languages (ESOL) teachers understand about social and academic language, what instructional strategies they use for Limited English Proficient (LEP) students, and how these concepts are operationalized in their daily practice. ^ This was a mixed method study incorporating both quantitative and qualitative data collection and interpretation. Written questionnaires and individual interviews addressed the questions on teachers' definitions of social and academic language and their strategy use. Classroom observations provided verification of their definitions and their descriptions of instruction for academic language. ^ Findings indicated that teachers' definitions of social and academic language were still developing and that there were ambiguities in identifying examples of social and academic language. The use of graphic organizers or visual supports, groups or peer partners, role play or drama, and modeling were the strategies teachers consistently listed for beginner, intermediate, advanced and multiple level classes. Additionally, teachers' descriptions of their instruction were congruent with what was observed in their classroom practice. ^ It appeared that this population of secondary ESOL teachers was in the process of evolving their definitions of social and academic language and were at different stages in this evolution. Teachers' definitions of language influenced their instruction. Furthermore, those who had clear constructs of language were able to operationalize them in their classroom instruction. ^

The will to write: Students' and teachers' perceptions of writing

This study investigated the perceptions of writing among secondary and post-secondary students and their teachers. The focus was on students' writing philosophy and influences, perceptions of the writing process, and perceptions of student writing skills, high stakes assessment tests, and writing across the curriculum. ^ An ethnographic case study was used to investigate the perceptions of writing among ten students and their English teachers in two high schools, a community college, and a university. To establish balance and ethnic plurality, seven females and three males representing the four large ethnic groups in South Florida—African American, Haitian American, European American and Latino—participated. During one four-month term, data from written samples of students' writing, formal and informal interviews, a student focus group, field notes, classroom observations, and a “think-aloud” protocol were collected. ^ Four themes emerged. First, Florida's writing assessment test has a negative influence on students' perceptions of writing. Students' motivation and attitudes as well as their confidence in their abilities were affected by practice and preparation in “recital writing.” Second, writing is a vehicle of social and personal transformation. Students believed that writing is a mean to connect to others and to create change in schools and communities. Third, students lacked the ability to connect writing, thinking and learning. Although students and teachers agree with statements about this connection, students failed to see the relevance of thinking and learning through writing in current or future courses, or in their future careers. Finally, writing context, teachers, schools, peers and gender influenced writing perceptions. Students believed that their writing philosophy, writing process, and perceptions of writing in academia and in the workplace are connected to these five factors. ^ The effect of the Florida writing test pervades students' and teachers' writing perceptions, making a stronger case for writing across the curriculum than previous research. Writing should help students see knowledge as interrelated, honor students' interests and values, and build relationships between and among students, schools and communities. In designing and implementing methods that support and sustain student writing, teachers should provide students with multiple opportunities to expand knowledge, learning, and connection through writing. ^

Reading comprehension and mathematical concept acquisition through the use of math stories with bilingual children

Math storybooks are picture books in which the understanding of mathematical concepts is central to the comprehension of the story. Math stories have provided useful opportunities for children to expand their skills in the language arts area and to talk about mathematical factors that are related to their real lives. The purpose of this study was to examine bilingual children's reading and math comprehension of the math storybooks. ^ The participants were randomly selected from two Korean schools and two public elementary schools in Miami, Florida. The sample consisted of 63 Hispanic American and 43 Korean American children from ages five to seven. A 2 x 3 x (2) mixed-model design with two between- and one within-subjects variable was used to conduct this study. The two between-subjects variables were ethnicity and age, and the within-subjects variable was the subject area of comprehension. Subjects were read the three math stories individually, and then they were asked questions related to reading and math comprehension. ^ The overall ANOVA using multivariate tests was conducted to evaluate the factor of subject area for age and ethnicity. As follow-up tests for a significant main effect and a significant interaction effect, pairwise comparisons and simple main effect tests were conducted, respectively. ^ The results showed that there were significant ethnicity and age differences in total comprehension scores. There were also age differences in reading and math comprehension, but no significant differences were found in reading and math by ethnicity. Korean American children had higher scores in total comprehension than those of Hispanic American children, and they showed greater changes in their comprehension skills at the younger ages, from five to six, whereas Hispanic American children showed greater changes at the older ages, from six to seven. Children at ages five and six showed higher scores in reading than in math, but no significant differences between math and reading comprehension scores were found at age seven. ^ Through schooling with integrated instruction, young bilingual children can move into higher levels of abstraction and concepts. This study highlighted bilingual children's general nature of thinking and showed how they developed reading and mathematics comprehension in an integrated process. ^

The thermodynamics and statistical mechanics of protein folding

The physics of self-organization and complexity is manifested on a variety of biological scales, from large ecosystems to the molecular level. Protein molecules exhibit characteristics of complex systems in terms of their structure, dynamics, and function. Proteins have the extraordinary ability to fold to a specific functional three-dimensional shape, starting from a random coil, in a biologically relevant time. How they accomplish this is one of the secrets of life. In this work, theoretical research into understanding this remarkable behavior is discussed. Thermodynamic and statistical mechanical tools are used in order to investigate the protein folding dynamics and stability. Theoretical analyses of the results from computer simulation of the dynamics of a four-helix bundle show that the excluded volume entropic effects are very important in protein dynamics and crucial for protein stability. The dramatic effects of changing the size of sidechains imply that a strategic placement of amino acid residues with a particular size may be an important consideration in protein engineering. Another investigation deals with modeling protein structural transitions as a phase transition. Using finite size scaling theory, the nature of unfolding transition of a four-helix bundle protein was investigated and critical exponents for the transition were calculated for various hydrophobic strengths in the core. It is found that the order of the transition changes from first to higher order as the strength of the hydrophobic interaction in the core region is significantly increased. Finally, a detailed kinetic and thermodynamic analysis was carried out in a model two-helix bundle. The connection between the structural free-energy landscape and folding kinetics was quantified. I show how simple protein engineering, by changing the hydropathy of a small number of amino acids, can enhance protein folding by significantly changing the free energy landscape so that kinetic traps are removed. The results have general applicability in protein engineering as well as understanding the underlying physical mechanisms of protein folding. ^

Developing performance measures of mangrove wetlands using simulation models of hydrology, nutrient biogeochemistry, and community dynamics

The goal of mangrove restoration projects should be to improve community structure and ecosystem function of degraded coastal landscapes. This requires the ability to forecast how mangrove structure and function will respond to prescribed changes in site conditions including hydrology, topography, and geophysical energies. There are global, regional, and local factors that can explain gradients of regulators (e.g., salinity, sulfides), resources (nutrients, light, water), and hydroperiod (frequency, duration of flooding) that collectively account for stressors that result in diverse patterns of mangrove properties across a variety of environmental settings. Simulation models of hydrology, nutrient biogeochemistry, and vegetation dynamics have been developed to forecast patterns in mangroves in the Florida Coastal Everglades. These models provide insight to mangrove response to specific restoration alternatives, testing causal mechanisms of system degradation. We propose that these models can also assist in selecting performance measures for monitoring programs that evaluate project effectiveness. This selection process in turn improves model development and calibration for forecasting mangrove response to restoration alternatives. Hydrologic performance measures include soil regulators, particularly soil salinity, surface topography of mangrove landscape, and hydroperiod, including both the frequency and duration of flooding. Estuarine performance measures should include salinity of the bay, tidal amplitude, and conditions of fresh water discharge (included in the salinity value). The most important performance measures from the mangrove biogeochemistry model should include soil resources (bulk density, total nitrogen, and phosphorus) and soil accretion. Mangrove ecology performance measures should include forest dimension analysis (transects and/or plots), sapling recruitment, leaf area index, and faunal relationships. Estuarine ecology performance measures should include the habitat function of mangroves, which can be evaluated with growth rate of key species, habitat suitability analysis, isotope abundance of indicator species, and bird census. The list of performance measures can be modified according to the model output that is used to define the scientific goals during the restoration planning process that reflect specific goals of the project.

Dynamics of ecosystem metabolism and flocculent detritus transport in estuarine Taylor River

Estuaries and estuarine wetlands are ecologically and societally important systems, exhibiting high rates of primary production that fuel offshore secondary production. Hydrological processes play a central role in shaping estuarine ecosystem structure and function by controlling nutrient loading and the relative contributions of marine and terrestrial influences on the estuary. The Comprehensive Everglades Restoration Plan includes plans to restore freshwater delivery to Taylor Slough, a shallow drainage basin in the southern Everglades, ultimately resulting in increased freshwater flow to the downstream Taylor River estuary. The existing seasonal and inter-annual variability of water flow and source in Taylor River affords the opportunity to investigate relationships between ecosystem function and hydrologic forcing. Estimates of aquatic ecosystem metabolism, derived from free-water, diel changes in dissolved oxygen, were combined with assessments of wetland flocculent detritus quality and transport within the context of seasonal changes in Everglades hydrology. Variation in ecosystem gross primary production and respiration were linked to seasonal changes in estuarine water quality using multiple autoregression models. Furthermore, Taylor River was observed to be net heterotrophic, indicating that an allochthonous source of carbon maintained ecosystem respiration in excess of autochthonous primary production. Wetland-derived detritus appears to be an important vector of energy and nutrients across the Everglades landscape; and in Taylor River, is seasonally flushed into ponded segments of the river where it is then respired. Lastly, seasonal water delivery appears to govern feedbacks regulating water column phosphorus availability in the Taylor River estuary.

Diatom-based Models for Inferring Hydrology and Periphyton Abundance in a Subtropical Karstic Wetland: Implications for Ecosystem-Scale Bioassessment

We developed diatom-based prediction models of hydrology and periphyton abundance to inform assessment tools for a hydrologically managed wetland. Because hydrology is an important driver of ecosystem change, hydrologic alterations by restoration efforts could modify biological responses, such as periphyton characteristics. In karstic wetlands, diatoms are particularly important components of mat-forming calcareous periphyton assemblages that both respond and contribute to the structural organization and function of the periphyton matrix. We examined the distribution of diatoms across the Florida Everglades landscape and found hydroperiod and periphyton biovolume were strongly correlated with assemblage composition. We present species optima and tolerances for hydroperiod and periphyton biovolume, for use in interpreting the directionality of change in these important variables. Predictions of these variables were mapped to visualize landscape-scale spatial patterns in a dominant driver of change in this ecosystem (hydroperiod) and an ecosystem-level response metric of hydrologic change (periphyton biovolume). Specific diatom assemblages inhabiting periphyton mats of differing abundance can be used to infer past conditions and inform management decisions based on how assemblages are changing. This study captures diatom responses to wide gradients of hydrology and periphyton characteristics to inform ecosystem-scale bioassessment efforts in a large wetland.

Mapping and Assessing Fire Damage on Broadleaved Forest Communities in Big Cypress National Preserve

Within Big Cypress National Preserve (BICY), oak-dominated forests and woodlands as well as tropical and temperate hardwood hammocks are integral components of the landscape and are biodiversity hotpots for both flora and fauna. These broadleaved forest communities serve as refugia for many of the Preserve’s wildlife species during prolonged flooding and fires. However, both prolonged flooding and severe fires, which are important and necessary disturbance vectors within this landscape, can have deleterious effects on these forested communities. This is particularly true in the case of fires, which under extreme conditions associated with drought and elevated fuel loads, can burn through these forested communities consuming litter and understory vegetation and top killing most, if not all, of the trees present.

Application of biomarkers and compound specific stable isotopes for the assessment of hydrology as a driver of organic matter dynamics in the Everglades ecosystem

The Everglades is a sub-tropical coastal wetland characterized among others by its hydrological features and deposits of peat. Formation and preservation of organic matter in soils and sediments in this wetland ecosystem is critical for its sustainability and hydrological processes are important divers in the origin, transport and fate of organic matter. With this in mind, organic matter dynamics in the greater Florida Everglades was studied though various organic geochemistry techniques, especially biomarkers, bulk and compound specific δ13C and δD isotope analysis. The main objectives were focused on how different hydrological regimes in this ecosystem control organic matter dynamics, such as the mobilization of particulate organic matter (POM) in freshwater marshes and estuaries, and how organic geochemistry techniques can be applied to reconstruct Everglades paleo-hydrology. For this purpose organic matter in typical vegetation, floc, surface soils, soil cores, and estuarine suspended particulates were characterized in samples selected along hydrological gradients in the Water Conservation Area 3, Shark River Slough and Taylor Slough. ^ This research focused on three general themes: (1) Assessment of the environmental dynamics and source-specific particulate organic carbon export in a mangrove-dominated estuary. (2) Assessment of the origin, transport and fate of organic matter in freshwater marsh. (3) Assessment of historical changes in hydrological conditions in the Everglades (paleo-hydrology) though biomarkes and compound specific isotope analyses. This study reports the first estimate of particulate organic carbon loss from mangrove ecosystems in the Everglades, provides evidence for particulate organic matter transport with regards to the formation of ridge and slough landscapes in the Everglades, and demonstrates the applicability of the combined biomarker and compound-specific stable isotope approach as a means to generate paleohydrological data in wetlands. The data suggests that: (1) Carbon loss from mangrove estuaries is roughly split 50/50 between dissolved and particulate carbon; (2) hydrological remobilization of particulate organic matter from slough to ridge environments may play an important role in the maintenance of the Everglades freshwater landscape; and (3) Historical changes in hydrology have resulted in significant vegetation shifts from historical slough type vegetation to present ridge type vegetation. ^

Landscape shaping the economy of small coastal villages

Some years ago visitors and natives had a different way of enjoying the landscape of the coastal villages located in Santa Elena Province, in Ecuador. Nowadays natives of those towns are concerned about the emergent tourist industry, which is not just offering lodging but also it is increasing the construction of vacation homes or second homes. This development is showing notorious social and spatial changes in those coastal towns. Since 80's, the real-estate investments in vacation homes have not stopped. In addition, it has been increasing year in year out, to the north of the Province. Nowadays there are not just homes but also luxury complex of buildings attracting more and more seasonal tourists. This real estate growing has been constantly changing the landscape and shaping the economy of those towns. The authorities in this province are aware of those effects citing in the Province's Master Plan of Development the lack of land use policies. This study aims to describe the socioeconomic activity of coastal villages located in Santa Elena Province, which - during many years - have a resource-based economy: agriculture and fishing economy; but during this last years they have been trying to switch it to tourism. The analysis of spatial changes of the landscape and its effects as a consequence of the land use is another goal of this work. Finally, this study describes the quest of new natural tourist attractions that villagers and stakeholders have taken recently. Key words: Nature and society, sociospatial, rural landscape, coastal landscape, tourism.

"Hamlet" and Marginality

This research aims to explore the place of marginality (or that which is not the immediate focus of narrative) in the context of the play and through the examination of the characters of Fortinbras and Horatio, in William Shakespeare’s Hamlet. The intended outcome is to encourage diversified perspectives and approaches to the play by focusing on the marginal themes and/or characters. The chapters address the characters of Fortinbras and Horatio; the first inverts the protagonist/foil relationship by reading Hamlet as a foil to Fortinbras, while the second uses Freud’s “The Uncanny” as a way to understand Horatio’s role in the play, as its uncanniest phenomena. Both are marginal to the text, but both are significant to the understanding of the text. Essentially, the objective is to encourage readings of the play, and of narratives, that appreciate the complexity of marginality, in order to broaden the language for future research.

On Record: Soundscapes as Metaphor and Physical Manifestation of Memory in Early Holocaust Novels and Contemporary Criticism

This thesis compares two perspectives on the production of Holocaust memory: a novel that leads up to The Holocaust in Britain and one that reflects the hindsight perspective of a liberator in the Soviet Union. The novels are Virginia Woolf’s BETWEEN THE ACTS and Vasily Grossman’s LIFE AND FATE. The analysis offers a locus of analysis for the diasporic literary energy created by the catastrophe in the 20th and 21st centuries. The project offers a theorized standpoint on the role of literature on official historical archives. Proposing a method through which contemporary readers can engage the diasporic event of The Holocaust, the project adopts both the extended metaphor and literal expression of soundscapes. Soundscapes encompass the immaterial processes of memorialization and the literal sonic textures developed in Holocaust novels. The critical perspective incorporates contemporary notions of narratology, archival practices, and cultural manifestations of language into the notion of literary ethnomusicology.

Reimagining Reflection: Gender, Student Perception, and Reflective Writing in the Composition Classroom

The purpose of this thesis is to discover any existing correlation between gender and student perceptions of reflective writing in the composition classroom. Seventy-five students at Florida International University participated in a survey that explored their approaches to and understanding of reflective writing. In order to connect the specific results of this study to the larger context of composition theory, this thesis includes an examination of the theoretical background of gender and reflective writing. The results of the survey indicate that the only identifiable difference between male and female student responses resulted from their definitions of reflective writing. Beyond this difference, however, there were no significant variances in student perceptions of reflective writing. The response of these students at FIU indicates a shift in expected gender norms and suggests a reconsideration of what it means to be a gendered writer in the composition classroom.

Treason and trial : consuetudines and law in the romances of Chrétien de Troyes and the lais of Marie de France

Treason, in the romances of Chrdtien de Troyes and the lais of Marie de France, is explored more often as afin' amor problem than as a legal issue with its concomitant sociopolitical ramifications. It is precisely the historical function of literature within the ambit of court culture that appears to have shaped the legal context of the poems of Chrdtien de Troyes and the lais of Marie de France. Counterpoising the literary treatment of treason in Le Chevalier au Lion and Lanval with actions and definitions of treachery by contemporary, twelfth-century chronicle and customary law sources reveals that the conceptualized, fictional world of Chrdtien's Yvain closely reflects the workings of the Capetian society Chretien experienced. Marie's Lanval reflects as well the historical impressions of the Angevin court with which she had familiarity, a court whose concept of treason leaned more toward the maiestas concept found in Roman jurisprudence tradition.
