English Devotional Song of the Seventeenth Century in Printed Collections from 1638 to 1693: A Study of Music and Culture

Description: Seventeenth-century England witnessed profound historical, theological, and musical changes. A king was overthrown and executed; religion was practiced fervently and disputed hotly; and English musicians fell under the influence of the Italian stile nuovo. Many devotional songs were printed, among them those which reveal influences of this style. These English-texted sacred songs for one to three solo voices with continuo--not based upon a previously- composed hymn or psalm tune—are emphasized in this dissertation. Chapter One treats definitions, past neglect of the genre by scholars, and the problem of ambiguous terminology. Chapter Two is an examination of how religion and politics affected musical life, the hiatus from liturgical music from 1644 to 1660 causing composers to contribute to the flourishing of devotional music for home worship and recreation. Different modes of seventeenth-century devotional life are discussed in Chapter Three. Chapter Four provides documentation for use of devotional music, diaries and memoirs of the period revealing the use of several publications considered in this study. Baroque musical aesthetics applied to devotional song and its raising of the affections towards God are discussed in Chapter Five. Chapter Six traces the influence of Italian monody and sacred concerto on English devotional song. The earliest compositions by an Englishman working in the stile nuovo are Henry Lawes' 1638 hymn tunes with continuo. Collections of two- and three-voice compositions by Child, the Lawes brothers, Wilson, and Porter, published from 1639 to 1657, comprise Chapter Seven, as well as early devotional works of Locke. Chapter Eight treats Restoration devotional song-- compositions for one to three voices and continuo, mostly of a more secular and dramatic style than works discussed in earlier. The outstanding English Baroque composers--Locke, Humfrey, Blow, and Purcell--are represented, and the apex of this style is found in the latest seventeenth-century publication of devotional song, ...

English language learners: Does summer school make a difference in young children's literacy scores?

Description: Many school districts consider literacy and oral language as a top priority for pre-kindergarten students. In the district under study, pre-kindergarten English language learner (ELL) students are encouraged to attend a special summer school program to increase their oral language ability in English. This study compared three groups of children: ELL students attending summer school v. ELL students not attending summer school v. English speaking students not attending summer school. The students' primary reading inventory scores from the end of pre-kindergarten to the middle of kindergarten in the areas of reading, writing and oral language were compared. As expected, ELLs who attended summer school showed significant growth in oral language development from the beginning of summer school to the end of summer school. While it was hypothesized that ELL students attending summer school would show more improvement in oral language than other children over time, there was no significant difference between summer school and non-summer school children's scores by the middle of kindergarten.

English Methods Courses in Texas Preparation for the Essential Elements

Description: This study analyzes the congruence between the objectives of secondary-level English methods courses in Texas universities and the objectives of the state-mandated high school curriculum (the essential elements) in language arts. A questionnaire was used to obtain information from 26 English methods instructors at 22 universities in Texas. The data obtained from these questionnaires reveal that these instructors strongly emphasize preparing prospective English teachers to teach the essential elements of composition. Other significant findings include: (1) the lack of emphasis in the English methods course on strategies for teaching the essential elements of language, when those elements are unrelated to composition, and (2) the lack of uniformity which characterizes the organization of the English methods course at major Texas universities.

Enhanced Coarse-Graining for Multiscale Modeling of Elastomers

Description: One of the major goal of the researchers is to reduce energy loss including nanoscale to the structural level. For instance, around 65% of fuel energy is lost during the propulsion of the automobiles, where 11% of the loss happens at tires due to rolling friction. Out of that tire loss, 90 to 95% loss happens due to hysteresis of tire materials. This dissertation focuses on multiscale modeling techniques in order to facilitate the discovery new rubber materials. Enhanced coarse-grained models of elastomers (thermoplastic polyurethane elastomer and natural rubber) are constructed from full-atomic models with reasonable repeat units/beads associated with pressure-correction for non-bonded interactions of the beads using inverse Boltzmann method (IBM). Equivalent continuum modeling is performed with volumetric/isochoric loading to predict macroscopic mechanical properties using molecular mechanics (MM) and molecular dynamics (MD). Glass-transition and rate-dependent mechanical properties along with hysteresis loss under uniaxial deformation is predicted with varying composition of the material. A statistical non-Gaussian treatment of a rubber chain is performed and linked with molecular dynamics in order predict hyperelastic material constants without fitting with any experimental data.

Enhanced learning performance in the middle school classroom through increased student motivation, by the use of educational software and question-based gaming technology.

Description: The purpose of this research was to determine if the introduction of a competitive and collaborative computer-based gaming software system into middle school classrooms would result in improved attendance and grades, and motivate students to have a greater interest in their studies. This study was conducted over a 6 week period, with attendance and performance data being collected from 284 students. Two quantitative surveys were used to measure course interest and motivation: (a) the Course Interest Survey (CIS), and (b) the Instructional Materials Motivation Survey (IMMS). Participation in these surveys consisted of 84 students taking the CIS and 40 students taking the IMMS. The results indicated that the experimental group showed statistically better scores than the comparison group in attendance and performance. Students participating in the experimental group had significantly lower mean ranks of absenteeism compared to students in the comparison group. Results also revealed significant differences on grades. Students that were in the experimental group had significantly higher grades compared to students that were in the comparison group. Results of the CIS suggest that a statistically significant difference does not exist on Attention, Relevance, Confidence, and Satisfaction between the experimental and comparison groups. Results of the means and standard deviations for the IMMS Motivation Scores fell somewhere between Moderately true and Mostly true. This research study suggests that student's attendance and performance can be improved when quiz based gaming software that is both collaborative and competitive is used regularly in the classroom. However, for student's that participated in the gaming software, their interest in studying the subject doesn't appear to be significantly different from students that did not participate.

Enhancement by Human Chorionic Gonadotropin of Transformation of Chick Embryo Fibroblasts and Rat Kidney Cells Infected with Temperature-Sensitive and Wild Type Rous Sarcoma Viruses

Description: Human chorionic gonodotropin (HCG) affected in various ways cell cultures infected with strains of Rous sarcoma virus (RSV). The cell cultures studied were chick embryo fibroblasts (CEF), normal rat kidney cells infected with temperature-sensitive mutant (LA31-NRK) and a wild type RSV (B77-NRK). HCG increased the rate of transformation and viral titer of CEF cells infected with RSV, but not B77-NRK. HCG increased significantly transformation rates of LA31-NRK, only if the temperature sensitive transformation process was first delayed by incubation at non-permissive temperatures. It is suggested that some postinfective, pretransformational event(s) may operate before viralmediated transformation rates are increased by HCG.

Enhancement of Light Emission from Metal Nanoparticles Embedded Graphene Oxide

Description: A fully oxidized state of graphene behaves as a pure insulating while a pristine graphene behaves as a pure conducting. The in-between oxide state in graphene which is the controlled state of oxide behaves as a semiconducting. This is the key condition for tuning optical band gap for the better light emitting property. The controlling method of oxide in graphene structure is known as reduction which is the mixed state of sp2 and sp3 hybrid state in graphene structure. sp2 hybridized domains correspond to pure carbon-carbon bond i.e. pristine graphene while sp3 hybridized domains correspond to the oxide bond with carbon i.e. defect in graphene structure. This is the uniqueness of the graphene-base material. Graphene is a gapless material i.e. having no bandgap energy and this property prevents it from switching device applications and also from the optoelectronic devices applications. The main challenge for this material is to tune as a semiconducting which can open the optical characteristics and emit light of desired color. There may be several possibilities for the modification of graphene-base material that can tune a band gap. One way is to find semiconducting property by doping the defects into pristine graphene structure. Other way is oxides functional groups in graphene structure behaves as defects. The physical properties of graphene depend on the amount of oxides present in graphene structure. So if there are more oxides in graphene structure then this material behaves as a insulating. By any means if it can be reduced then oxides amount to achieve specific proportion of sp2 and sp3 that can emit light of desired color. Further, after achieving light emission from graphene base material, there is more possibility for the study of non-linear optical property. In this work, plasmonic effect in graphene oxide has been focused. Mainly there are two ...

The enhancement of machine translation for low-density languages using Web-gathered parallel texts.

Description: The majority of the world's languages are poorly represented in informational media like radio, television, newspapers, and the Internet. Translation into and out of these languages may offer a way for speakers of these languages to interact with the wider world, but current statistical machine translation models are only effective with a large corpus of parallel texts - texts in two languages that are translations of one another - which most languages lack. This thesis describes the Babylon project which attempts to alleviate this shortage by supplementing existing parallel texts with texts gathered automatically from the Web -- specifically targeting pages that contain text in a pair of languages. Results indicate that parallel texts gathered from the Web can be effectively used as a source of training data for machine translation and can significantly improve the translation quality for text in a similar domain. However, the small quantity of high-quality low-density language parallel texts on the Web remains a significant obstacle.

Enhancement of spatial ability in girls in a single-sex environment through spatial experience and the impact on information seeking.

Description: The test scores of spatial ability for women lag behind those of men in many spatial tests. On the Mental Rotations Test (MRT), a significant gender gap has existed for over 20 years and continues to exist. High spatial ability has been linked to efficiencies in typical computing tasks including Web and database searching, text editing, and computer programming. The relationships between the components of visuospatial ability and performance are complex. However, research strongly indicates that a connection exists, and further research is necessary to determine the interactions between the variables of environment, genetics, and spatial training. Spatial experience can enhance spatial skills. However, to what extent spatial skills can be enhanced in female adolescents through a spatial curriculum to reduce the gap in scores has not been fully researched, nor has the impact of spatial skill on information seeking. This research project investigated spatial skill in adolescent females by examining (1) the extent to which the intervention of teaching a spatial curriculum in a single-sex setting could improve mental rotation test scores, and (2) the impact of spatial skills on an information seeking task in a single-sex setting. The extent to which a spatial visualization curriculum can improve MRT scores from a pretest to a posttest for girls was the first factor examined using a spatial visualization curriculum. The information seeking task used 4 tasks from a doctoral study and utilized the scholarly journal database JSTOR® (JSTOR, Ann Arbor, MI, www.jstor.org).

Enhancements of Mechanical, Thermal Stability, and Tribological Properties by Addition of Functionalized Reduced Graphene Oxide in Epoxy

Description: The effects of octadecylamine-functionalized reduced graphene oxide (FRGO) on the frictional and wear properties of diglycidylether of bisphenol-A (DGEBA) epoxy are studied using a pin-on-disk tribometer. It was observed that the addition of FRGO significantly improves the tribological, mechanical, and thermal properties of epoxy matrix. Graphene oxide (GO) was functionalized with octadecylamine (ODA), and then reduction of oxygen-containing functional groups was carried out using hydrazine monohydrate. The Raman and x-ray photoelectron spectroscopy studies confirm significant reduction in oxygen-containing functional groups and formation of ODA functionalized reduced GO. The nanocomposites are prepared by adding 0.1, 0.2, 0.5 and 1.0 wt % of FRGO to the epoxy. The addition of FRGO increases by more than an order of magnitude the sliding distance during which the dynamic friction is ≤ 0.1. After this distance, the friction sharply increases to the range of 0.4 - 0.5. We explain the increase in sliding distance during which the friction is low by formation of a transfer film from the nanocomposite to the counterface. The wear rates in the low and high friction regimes are approximately 1.5 x 10-4 mm3/N·m and 5.5 x 10-4 mm3/N·m, respectively. The nanocomposites exhibit a 74 % increase in Young’s modulus with 0.5 wt. % of FRGO, and an increase in glass transition and thermal degradation temperatures.

Enhancing skill maintenance through relapse prevention strategies: a comparison of two models.

Description: In a quasi-experimental field study, two posttraining interventions composed of relapse prevention (RP) strategies were compared and tested for the effects on participant transfer outcomes. Participant retention of training content, skill maintenance, use of relapse prevention strategies, and self-efficacy served as the dependent variables. Self-efficacy was also tested as a mediator between the experimental treatment levels and both participant skill maintenance and participant use of RP strategies. Participants (n = 39) included managers, directors, and supervisors from various departments within a multi-national telecommunications organization located in a large southern city. After participating in a four-hour leadership development training, two of the three groups participated in a 30-40 minute training where they received one of two RP interventions. One intervention included the steps of (1) identifying potential obstacles to positive training transfer, (2) predicting the first lapse to pretraining behavior, and (3) applying relevant coping strategies to thwart a lapse. The alternative RP intervention included the same steps in addition to a goal setting step. Descriminant descriptive analysis was used to test for group differences across the response variables and to identify on which variables the groups differed. Three separate regression equations were used to test for the mediating relationship of self-efficacy between the RP treatment levels and participant skill maintenance and participant use of RP strategies. Results indicated minimal, but non-statistically significant results between treatment levels and each of the response variables. Self-efficacy was not found to mediate the relationship between RP treatment level and participant skill maintenance or participant use of RP strategies, but did function as a strong predictor of both variables. Suggestions for future research include using additional motivational and efficacy variables to better explore group differences and including efficacy-inducing methods both in training design and as part of a transfer intervention to enhance training transfer. Further, ...

Enhancing User Search Experience in Digital Libraries with Rotated Latent Semantic Indexing

Description: This study investigates a semi-automatic method for creation of topical labels representing the topical concepts in information objects. The method is called rotated latent semantic indexing (rLSI). rLSI has found application in text mining but has not been used for topical labels generation in digital libraries (DLs). The present study proposes a theoretical model and an evaluation framework which are based on the LSA theory of meaning and investigates rLSI in a DL environment. The proposed evaluation framework for rLSI topical labels is focused on human-information search behavior and satisfaction measures. The experimental systems that utilize those topical labels were built for the purposes of evaluating user satisfaction with the search process. A new instrument was developed for this study and the experiment showed high reliability of the measurement scales and confirmed the construct validity. Data was collected through the information search tasks performed by 122 participants using two experimental systems. A quantitative method of analysis, partial least squares structural equation modeling (PLS-SEM), was used to test a set of research hypotheses and to answer research questions. The results showed a not significant, indirect effect of topical label type on both guidance and satisfaction. The conclusion of the study is that topical labels generated using rLSI provide the same levels of alignment, guidance, and satisfaction with the search process as topical labels created by the professional indexers using best practices.

Enkephalin Metabolism in Exercise Stress

Description: Investigators have suggested that opiate peptide hormones released during exercise stress may play an important role in athletic performance or perceived effort. Their enzymatic inactivation in the periphery is of considerable interest since the opiate peptides may be regulated by enkephalin hydrolyzing enzyme (EHA). In this study, the relationship between maximal aerobic capacity (VO_2max) and EHA activity was examined in two distinct fitness groups. When the metabolic capacity was evaluated in whole blood, the unfit subjects metabolized the peptides significantly faster than their fit counterparts. Since the total enzyme activity of the two groups is similar, the difference in metabolism must result from circulating factors in the trained athletes, which slow the rate of peptide inactivation.

The Enlightenment and the Englishwoman

Description: The present study investigates the failure of the Enlightenment to liberate Englishwomen from the prejudices society and law imposed upon them. Classifying social classes by lifestyle, the roles of noble, middleclass, and criminal women, as well as the attitudes of contemporary writers of both sexes, are analyzed. This investigation concludes that social mores limited noblewomen to ornamental roles and condemned them to exist in luxurious boredom; forced middle-class women to emulate shining domestic images which contrasted sharply with the reality of their lives; subjected women of desperate circumstances to a criminal code rendered erratic and inconsistent by contemporary attitudes, and impelled the Enlightenment to invent new defenses for old attitudes toward women.

The Enlightenment Legacy of David Hume

Description: Although many historians assert the unity of the Enlightenment, their histories essentially belie this notion. Consequently, Enlightenment history is confused and meaningless, urging the reader to believe that diversity is similarity and faction is unity. Fundamental among the common denominators of these various interpretations, however, are the scientific method and empirical observation, as introduced by Newton. These, historians acclaim as the turning point when mankind escaped the ignorance of superstition and the oppression of the church, and embarked upon the modern secular age. The Enlightenment, however, founders immediately upon its own standards of empiricism and demonstrable philosophical tenets, with the exception of David Hume. As the most consistent and fearless empiricist of the era, Hume's is by far the most "legitimate" philosophy of the Enlightenment, but it starkly contrasts the rhetoric and ideology of the philosophe community, and, therefore, defies attempts by historians to incorporate it into the traditional Enlightenment picture. Hume, then, exposes the Enlightenment dilemma: either the Enlightenment is not empirical, but rather the new Age of Faith Carl Becker proclaimed it, or Enlightenment philosophy is that of Hume. This study presents the historical characterization of major Enlightenment themes, such as method, reason, religion, morality, and politics, then juxtaposes this picture with the particulars (data) that contradict or seriously qualify it. As a result, much superficial analysis, wishful thinking, even proselytizing is demonstrated in the traditional Enlightenment characterization, especially with regard to the widely heralded liberal and progressive legacy of the era. In contrast, Hume's conclusions, based on the method of Newton-the essence of "enlightened" philosophy, are presented, revealing the authoritarian character (and legacy) of the Enlightenment as well as the utility and relevance of its method when honestly and rigorously applied. Through David Hume, the twentieth century can truly acquire what the Enlightenment promised—an understanding of human ...
