Language Behaviors and Social Strategies of English as Second Language and English as Primary Language Preschool Children During Computer Assisted Instruction Experiences

Language Behaviors and Social Strategies of English as Second Language and English as Primary Language Preschool Children During Computer Assisted Instruction Experiences

Date: August 1993
Creator: Emerson, Stacia B. (Stacia Brewster)
Description: This study describes the language behaviors and social strategies of English as Second Language (ESL) and English as Primary Language (EPL) pre-kindergarten students during cooperative Computer Assisted Instruction (CAI) experiences. Thirty-three pre-kindergarten subjects ages four to five years, were videotaped at two personal computers during self-selected center time. The sources of data for this descriptive study were a parent computer survey, videotapes, a subject interview derived from the Young Children's Computer Inventory, and written records.

Language Choice in the ESL and FL Classrooms: Teachers and Students Speak Out

Language Choice in the ESL and FL Classrooms: Teachers and Students Speak Out

Date: August 2006
Creator: Fernandez, Cody
Description: This paper compares English as a second language (ESL) and foreign language (FL) teachers' and students' perspectives regarding target language (TL) and first language (L1) use in the respective classrooms. Teachers and students were given questionnaires asking their opinions of a rule that restricts students' L1 use. Questionnaires were administered to 46 ESL students, 43 FL students, 14 ESL teachers, and 15 FL teachers in Texas secondary public schools. Results were analyzed using SPSS and R. Results demonstrated an almost statistical difference between perspectives of ESL and FL students regarding TL and L1 use, while teacher results demonstrated no statistical difference between the groups. Students had a more positive perspective of the rule than teachers.

Language Contact in the Inner City: the Acquisition of AAVE Features by Bilingual Hispanic Adolescents

Language Contact in the Inner City: the Acquisition of AAVE Features by Bilingual Hispanic Adolescents

Date: August 1998
Creator: Coleman, Jeffrey Alan
Description: Sociolinguists working in Northern urban areas have shown that Hispanics who come in contact with African Americans sometimes acquire features of African American vernacular English (AAVE). However, the acquisition of AAVE features by Hispanics in the South has yet to be documented. Specifically, no one has studied the kind of English that Hispanics in Texas are acquiring. The present study investigates this issue through research in an inner-city area of Dallas: Oak Cliff. During the past twenty-five years, the population of Oak Cliff has changed from a largely African American community to include a substantial number of Hispanics. Though their neighborhoods remain fairly separate, sports and gangs provide an arena for extended contact. This study investigates the extent to which AAVE grammatical features are being acquired by bilingual Hispanic adolescents who hang out with African Americans. The analysis for this paper focuses on the relationship between contact and depth of acquisition of AAVE syntactic constraints on the use the copula (is/are, be). Preliminary results show that be+V+ing as an habitual form has been incorporated into the grammar of these subjects, suggesting fundamental changes towards an AAVE grammatical system.

Language Drift in English : Gender Loss and Semantic Change

Language Drift in English : Gender Loss and Semantic Change

Date: August 1968
Creator: Parker, Mary A.
Description: In parallel passages from Old and Middle English and in noun cognates from Modern English, Old English, and Modern German, the most discernible elements of language drift are gender loss and word meaning change, respectively. They can be observed, discussed, and calculated to show a definite progression toward the development of Modern English.

The Language of Color in Shelley's Prometheus Unbound

The Language of Color in Shelley's Prometheus Unbound

Date: May 1969
Creator: Farrell, Charlotte Ann
Description: On the premise that examination of a poet's language can provide a valid and significant approach to the study of a work of art, this thesis proposes to make such a study of Prometheus Unbound, the major poetical work of Percy Bysshe Shelley, with specific attention to his use of color language.

Language Policy, Protest and Rebellion

Language Policy, Protest and Rebellion

Date: May 2001
Creator: Lunsford, Sharon
Description: The hypothesis that language discrimination contributes to protest and/or rebellion is tested. Constitutional language policy regarding administrative/judicial, educational and other matters is measured on three separate scales developed for this study; the status of each minority group's language under its country's policy is measured by another set of scales. Protest and rebellion variables are taken from Gurr's Minorities at Risk study. Findings include an indication that group language status contributes positively to protest and rebellion until a language attains moderate recognition by the government, at which point status develops a negative relationship with protest and rebellion, and an indication that countries with wider internal variations in their treatment of language groups experience higher levels of protest and rebellion on the part of minority groups.

Laser Cutting Machine: Justification of initial costs

Laser Cutting Machine: Justification of initial costs

Date: May 2001
Creator: Nagaraja, Dwarakish
Description: The Industrial Laser is firmly established in metalcutting as the tool of choice for many applications. The elevator division of Montgomery KONE Inc., in an effort to move towards quality, ontime, complete deliveries and 100% customer satisfaction, decided to invest in new equipment to improve manufacturing processes. A huge investment is proposed for a laser-cutting machine. It is the responsibility of Manufacturing Engineering to direct the management by justifying its benefits, which includes payback time and financial gains. Factors such as common line cutting, automated material handling system and cutting time were involved in justification of the initial cost of a laser-cutting machine. Comparative statistics on appropriate factors accurately determine and justify the initial cost of a laser-cutting machine.

Laser Deposition, Heat-treatment, and Characterization of the Binary Ti-xmn System

Laser Deposition, Heat-treatment, and Characterization of the Binary Ti-xmn System

Date: August 2013
Creator: Avasarala, Chandana
Description: The present research seeks to characterization of an additively manufactured and heat-treated Ti-xMn gradient alloy, a binary system that has largely been unexplored. In order to rapidly assess this binary system, compositionally graded Ti-xMn (0<x<15 wt%) specimens were fabricated using the LENS (Laser Engineered Net Shaping) and were subsequently heat-treated and characterized using a wide range of techniques. Microstructural changes with respect to the change in thermal treatments, hardness and chemical composition were observed and will be presented. These include assessments of both continuous cooling, leading to observations of both equilibrium and metastable phases, including the titanium martensites, and to direct aging studies looking for composition regimes that produce highly refined alpha precipitates – a subject of great interest given recent understandings of non-classical nucleation and growth mechanisms. The samples were characterized using SEM, EDS, TEM, and XRD and the properties probed using a Vickers Microhardness tester.
