Affordances of External Representations in Instructional Design: The Effect of Narrative and Imagery in Learning. (open access)

Affordances of External Representations in Instructional Design: The Effect of Narrative and Imagery in Learning.

Consisting of both theoretical and empirical inquires, this study examines the primary functions of narrative and the relationship between narrative and mental imagery. The study proposes a new framework to interpret semiotic resources. Combining this with the linguistic functional theory of Halliday (1978), a functional method to empirically investigate semiotic representations was also developed. In the empirical inquiry, the study developed a latent construct method to empirically test the effects of narrative in a real learning situation. This study is the first to investigate the functional relationship between narrative and mental imagery, and among the first to suggest a theory and empirically investigate representations of a multimodal nature. The study is also among the first to use latent constructs to investigate the learning experience in a real educational setting. Data were collected from 190 library professionals who enrolled in three sections (two in narrative and one in plain text) of an online course administered through Vista 4.0 and who completed the course and responded to several instruments. Essay data (n = 82 x 2) were analyzed using content analysis based on the narrative analysis framework developed. Quantitative data analysis methods include univariate data analysis, factor analysis, and structural equation modeling …

An Analysis of Joseph Schwantner's Concerto for Percussion and Orchestra (open access)

An Analysis of Joseph Schwantner's Concerto for Percussion and Orchestra

This analysis of Schwantner's Concerto is focused primarily on the pitch organization within the work, using terminology and concepts borrowed from those designed by Allen Forte in The Structure of Atonal Music. Discussion of pitch sets, their use, their derivation, their intervallic content, and their evolution throughout the piece are discussed. Additional discussion regarding Schwantner's style, orchestration techniques, textural manipulation with regard to form, are also discussed. Sources consist of the orchestral score, the two - piano reduction, and the solo percussion score. This document is in six chapters. The first discusses Schwantner's life and general musical style. The second is a brief discussion of terms in the field of pitch set organization. The third, fourth, and fifth chapters discuss in detail the musical materials themselves in each respective movement. Finally, the sixth chapter is a summary of the findings from the analysis.

An Analysis of the Opinions of University Students about the Current Situation of the Headscarf Dispute in Turkey (open access)

An Analysis of the Opinions of University Students about the Current Situation of the Headscarf Dispute in Turkey

This study examined the opinions of university students about the current situation of the headscarf dispute on the wearing of headscarves in Turkey. The influence of gender, the level of secularism, socioeconomic status and encounter with women wearing headscarves on opinions about the wearing of headscarves were analyzed in this study. The sample of this study was composed of 400 university students among whom there were 240 female and 160 male students. Moreover, the sample comprised university students from 50 universities from Turkey. The results indicated that the level of secularism and encounter with women wearing headscarves were distinguished as two determining factors of the diverse opinions of the university students on the topic. No association was found between the perceptions of university students about the issue and the independent variables of gender and socioeconomic status.

Analyze and Rebuild an Apparatus to Gauge Evaporative Cooling Effectiveness of Micro-Porous Barriers. (open access)

Analyze and Rebuild an Apparatus to Gauge Evaporative Cooling Effectiveness of Micro-Porous Barriers.

The sample used for evaporative cooling system is Fabric defender 750 with Shelltite finish. From the experimental data and equations we have diffusion coefficient of 20.9 ± 3.71 x 10-6 m2/s for fabric with one layer with 17%-20% fluctuations from the theory, 27.8 ± 4.5 x 10-6 m2/s for fabric with two layers with 6%-14% fluctuations from the theory and 24.9 ± 4.1 x 10-6 m2/s for fabric with three layers with 13%-16% fluctuations from the theory. Since the thickness of the fabric increases so the mass transport rate decreases so the mass transport resistance should be increases. The intrinsic mass resistances of Fabri-1L, Fabri-2L and Fabri-3L are respectively 104 ± 10.2 s/m, 154 ± 23 s/m and 206 ± 26 s/m from the experiment.

Applications of Molecular Genetics to Human Identity. (open access)

Applications of Molecular Genetics to Human Identity.

The primary objectives of this project were: 1. to develop improved methods for extraction of DNA from human skeletal remains, 2. to improve STR profiling success of low-copy DNA samples by employing whole genome amplification to amplify the total pool of DNA prior to STR analysis, and 3. to improve STR profiling success of damaged DNA templates by using DNA repair enzymes to reduce the number/severity of lesions that interfere with STR profiling. The data from this study support the following conclusions. Inhibitory compounds must be removed prior to enzymatic amplification; either during bone section pretreatment or by the DNA extraction method. Overall, bleach outperformed UV as a pretreatment and DNA extraction using silica outperformed microconcentration and organic extraction. DNA repair with PreCR™ A outperformed both whole genome amplification and repair with PreCR™ T6. Superior DNA extraction results were achieved using the A6 PMB columns (20 ml capacity column with 6 layers of type A glass fiber filter), and DNA repair with PreCR™ A led to an overall improvement in profile quality in most cases, although whole genome amplification was unsuccessful. Rapid, robust DNA isolation, successful amplification of loci from the sample-derived DNA pool, and an elimination of DNA damage …

Applications of Nanomanipulation Coupled to Nanospray Mass Spectrometry in Trace Fiber Analysis and Cellular Lipid Analysis. (open access)

Applications of Nanomanipulation Coupled to Nanospray Mass Spectrometry in Trace Fiber Analysis and Cellular Lipid Analysis.

The novel instrumentation of nanomanipulation coupled to nanospray mass spectrometry and its applications are presented. The nanomanipulator has the resolution of 10nm step sizes allowing for specific fine movement used to probe and characterize objects of interest. Nanospray mass spectrometry only needs a minimum sample volume of 300nl and a minimum sample size of 300attograms to analyze an analyte making it the ideal instrument to couple to nanomanipulation. The nanomanipulator is mounted to an inverted microscope and consists of 4 nano-positioners; these nano-positioners hold end-effectors and other tools used for manipulation. This original coupling has been used to enhance the current abilities of cellular probing and trace fiber analysis. Experiments have been performed to demonstrate the functionality of this instrument and its capabilities. Histidine and caffeine have been sampled directly from single fibers and analyzed. Lipid bodies from cotton seeds have been sampled indirectly and analyzed. The few applications demonstrated are only the beginning of nanomanipulation coupled to nanospray mass spectrometry and the possible applications are numerous especially with the ability to design and fabricate new end-effectors with unique abilities. Future study will be done to further the applications in direct cellular probing including toxicology studies and organelle analysis of …

Balanced Scorecards: An Experimental Study of the Effects of Linking the Evaluators' and Subordinates' Balanced Scorecards on Performance Evaluation. (open access)

Balanced Scorecards: An Experimental Study of the Effects of Linking the Evaluators' and Subordinates' Balanced Scorecards on Performance Evaluation.

In the early 1990s, Robert Kaplan and David Norton introduced and developed a new performance measurement and management system called the balanced scorecard (BSC). Most studies have found that evaluators tend to ignore or are not willing to use nonfinancial measures. This study attempts to examine whether the explicit linkage between the evaluator's BSC and the subordinate's BSC makes the evaluators use nonfinancial measures in performance evaluation. This study used an experimental design where subjects were asked to evaluate two managers' performance under explicit linkage versus nonexplicit linkage conditions. The difference between performance evaluation scores of the two managers under the two linkage conditions captures the influence of explicit linkage between BSCs on performance evaluation. I used regression analyses to test my hypothesis. The results of the regression analyses support my hypothesis. This study attempts to explore one possible reason for evaluators' not using nonfinancial measures much in performance evaluation. It is the first one that studies the influence of the linkage between the BSCs on performance evaluation.

Belle Musique and Fin' Amour: Thibaut de Champagne, Gace Brulé, and an Aristocratic Trouvére Tradition (open access)

Belle Musique and Fin' Amour: Thibaut de Champagne, Gace Brulé, and an Aristocratic Trouvére Tradition

Many consider Gace Brulé (c1160-c1213) and Thibaut IV, Count of Champagne, (1201-1253) to have been the greatest trouvères. Writers on this subject have not adequately examined this assumption, having focused their energies on such issues as tracking melodic variants of individual works as preserved in different song-books (or chansonniers), the interpretation of rhythm in performance, and creation of modern editions of these songs. This thesis examines the esteem enjoyed by Gace and Thibaut in both medieval and modern times which derives from their exemplarity of, rather than difference from their noble contemporaries.

Caught Between Jazz and Pop: The Contested Origins, Criticism, Performance Practice, and Reception of Smooth Jazz. (open access)

Caught Between Jazz and Pop: The Contested Origins, Criticism, Performance Practice, and Reception of Smooth Jazz.

In Caught Between Jazz and Pop, I challenge the prevalent marginalization and malignment of smooth jazz in the standard jazz narrative. Furthermore, I question the assumption that smooth jazz is an unfortunate and unwelcomed evolutionary outcome of the jazz-fusion era. Instead, I argue that smooth jazz is a long-lived musical style that merits multi-disciplinary analyses of its origins, critical dialogues, performance practice, and reception. Chapter 1 begins with an examination of current misconceptions about the origins of smooth jazz. In many jazz histories, the origins of smooth jazz are defined as a product of the jazz-fusion era. I suggest that smooth jazz is a distinct jazz style that is not a direct outgrowth of any mainstream jazz style, but a hybrid of various popular and jazz styles. Chapters 2 through 4 contain eight case studies examining the performers of crossover jazz and smooth jazz. These performers have conceived and maintained distinct communicative connections between themselves and their audiences. In the following chapter, the unfair treatment of popular jazz styles is examined. Many early and influential jazz critics sought to elevate jazz to the status of art music by discrediting popular jazz styles. These critics used specific criteria and emphasized notions …

A Comparative Analysis of Minoru Miki's Time For Marimba  and Concerto for Marimba and Orchestra (open access)

A Comparative Analysis of Minoru Miki's Time For Marimba and Concerto for Marimba and Orchestra

Minoru Miki's first two marimba compositions, Time for Marimba (1968) and Concerto for Marimba and Orchestra (1969) were composed at a revolutionary time-period for the marimba. Due to unique and innovative compositional techniques, Miki helped establish the marimba as a true concert instrument capable of performing music of the highest quality. As a pioneer in composing for marimba literature, Miki was able to capture the true essence of the marimba; a timeless quality that has helped Time for Marimba remain a part of the standard solo repertoire for the past forty years. The purpose of this study is to analyze and compare Minoru Miki's compositions, Time for Marimba and Concerto for Marimba and Orchestra. Composed within a year of each other, these works possess similar compositional techniques, and rhythmic and thematic relationships. This thesis includes a formal analysis and detailed comparisons of compositional techniques used in both works. Performance considerations, a brief biographical sketch of Miki and historical significance of Time for Marimba and Concerto for Marimba and Orchestra are also included.

Dawn in the Empty House (open access)

Dawn in the Empty House

The preface to this collection of poems, "Memory and The Myth of Lost Truth," explores the physical and metaphysical roles memory plays within poetry. It examines the melancholy frequently birthed from a particular kind poetic self-inquiry, or, more specifically, the feelings associated with recognizing the self's inability to re-inhabit the emotional experience of past events, and how poetry can redeem, via engaging our symbolic intuition, the faultiness of remembered history. Dawn in the Empty House is a collection of poems about the implications of human relationships, self-deception, and memory as a tool for self-discovery.

Diffusion across the digital divide: Assessing use of the Connecticut Digital Library (ICONN) in K-12 schools in Connecticut.

State digital libraries are manifestations of the diffusion of technology that has provided both access to and delivery of digital content. Whether the content is being accessed and used equitably in K-12 schools has not been assessed. Determining patterns of the diffusion of use across socioeconomic groups in K-12 schools may help measure the success of existing efforts to provide equitable access and use of digital content, and help guide policies and implementation to more effectively address remaining disparities. This study examined use of the Connecticut Digital Library (ICONN) in K-12 schools in Connecticut by determining annual patterns of use per school/district over a four-year period, using transaction log search statistics. The data were analyzed in the paradigm that Rogers (2003) describes as the first and second dimensions of the consequences of an innovation - the overall growth and the equality of the diffusion to individuals within an intended audience --- in this case, students in K-12 schools. Data were compared by school district and the established socioeconomic District Reference Groups (DRGs) defined by the Connecticut State Board of Education. At the time of this study, ICONN used aggregate data (total searches) for K-12 schools, but did not have relevant …

Direct Online/Offline Digital Signature Schemes. (open access)

Direct Online/Offline Digital Signature Schemes.

Online/offline signature schemes are useful in many situations, and two such scenarios are considered in this dissertation: bursty server authentication and embedded device authentication. In this dissertation, new techniques for online/offline signing are introduced, those are applied in a variety of ways for creating online/offline signature schemes, and five different online/offline signature schemes that are proved secure under a variety of models and assumptions are proposed. Two of the proposed five schemes have the best offline or best online performance of any currently known technique, and are particularly well-suited for the scenarios that are considered in this dissertation. To determine if the proposed schemes provide the expected practical improvements, a series of experiments were conducted comparing the proposed schemes with each other and with other state-of-the-art schemes in this area, both on a desktop class computer, and under AVR Studio, a simulation platform for an 8-bit processor that is popular for embedded systems. Under AVR Studio, the proposed SGE scheme using a typical key size for the embedded device authentication scenario, can complete the offline phase in about 24 seconds and then produce a signature (the online phase) in 15 milliseconds, which is the best offline performance of any known …

Effects of Fixed- and Variable-Ratio Token Exchange Schedules on Performance with Children with Autism (open access)

Effects of Fixed- and Variable-Ratio Token Exchange Schedules on Performance with Children with Autism

The research literature with nonhumans supports findings that token economies are a common component of training programs. The literature suggests that the schedule by which exchange opportunities become available determines the organization of behavioral performances in token economies to a great extent. This study sought to systematically document whether the dynamics observed in basic laboratory procedures will also be observed in a child diagnosed with autism spectrum disorders and whether altering schedules by which the exchange opportunities become available will attenuate these effects. The participant was exposed to two conditions: 1) a fixed token-production schedule (FR1) with a fixed token-exchange schedule (FR5) and 2) a fixed token-production schedule (FR1) with a variable token-exchange schedule (VR5). Results of the current study did not lend themselves to draw definitive conclusions that the patterns of responding observed in this experiment were in fact due to the change in the token exchange schedule.

Effects of Minimum Quantity Lubrication in Drilling 1018 Steel.

A common goal for industrial manufacturers is to create a safer working environment and reduce production costs. One common method to achieve this goal is to drastically reduce cutting fluid use in machining. Recent advances in machining technologies have made it possible to perform machining with minimum-quantity lubrication (MQL). Drilling takes a key position in the realization of MQL machining. In this study the effects of using MQL in drilling AISI 1018 steel with HSS tools using a vegetable based lubricant were investigated. A full factorial experiment was conducted and regression models were generated for both surface finish and hole size. Lower surface roughness and higher tool life were observed in the lowest speed and feed rate combination.

The Effects of Pre-Kindergarten on Spanish-Speaking Bilingual Students Taking the Third Grade TAKS Reading Test (open access)

The Effects of Pre-Kindergarten on Spanish-Speaking Bilingual Students Taking the Third Grade TAKS Reading Test

The purpose of this dissertation is to provide research and data examining the impact of pre-kindergarten on Spanish-speaking ESL students on the third grade TAKS Reading test scores. The two questions that guided this study are: (1) As measured by the third grade TAKS reading test, what is the relationship between those limited english proficient (LEP) Spanish-speaking children who attended a pre-kindergarten program and those who did not attend a pre-kindergarten program? and (2) As measured by the third grade TAKS Reading test, how do the test scores of those LEP Spanish-speaking third graders who attended the district's pre-k program in 2000-2001 and testing in 2005, differ from those who attended the district's pre-k program in 2001-2002 and testing in 2006? The research study used a quantitative methodology designed as causal-comparative analysis. Independent t-tests were used to determine if there were any significant differences in test scores of third graders between the two groups of students. Although the results of the statistical analysis revealed some isolated statistically significant differences between those Spanish-speaking bilingual students who attended pre-kindergarten and those who did not, the data showed no real differences in the test scores of those students.

Ego development and theoretical orientation among counseling students.

This study investigated potential relationships between master's level counseling students' levels of ego development and their identified orientations to one of six guiding theories of counseling; students' theoretical orientation classifications when classified according to the theory's domain of emphasis: affective, behavioral, or cognitive; students' degrees of confidence in identifying their theoretical orientations; and students' degrees of comfort in applying their theories in clinical practice. Seventy participants enrolled in a master's level practicum course completed the Washington University Sentence Completion Test, a measure of ego development, and the Counseling Theory Survey, a survey developed by the researcher, in order to identify students' identified theoretical orientations, students' degrees of confidence in identifying their theoretical orientations, and students' degrees of comfort in applying their theories in clinical practice. Ego development level was operationalized as a dichotomous variable consisting of level E5 and below and E6 and above, based on the developmental task attained at E6: a shift from emphasis on in-group identity to self-evaluated standards. To determine potential relationships between the students' ego development levels and their theoretical orientations and their orientations when classified by domain of emphasis, 2 x 4 and 2 x 3 Chi-square analyses were used.

Employment of dual frequency excitation method to improve the accuracy of an optical current sensor, by measuring both current and temperature. (open access)

Employment of dual frequency excitation method to improve the accuracy of an optical current sensor, by measuring both current and temperature.

Optical current sensors (OCSs) are initially developed to measure relatively large current over a wide range of frequency band. They are also used as protective devices in the event a fault occurs due to a short circuit, in the power generation and distribution industries. The basic principal used in OCS is the Faraday effect. When a light guiding faraday medium is placed in a magnetic field which is produced by the current flowing in the conductor around the magnetic core, the plane of polarization of the linearly polarized light is rotated. The angle of rotation is proportional to the magnetic field strength, proportionality constant and the interaction length. The proportionality constant is the Verdet constant V (λ, T), which is dependent on both temperature and wavelength of the light. Opto electrical methods are used to measure the angle of rotation of the polarization plane. By measuring the angle the current flowing in the current carrying conductor can be calculated. But the accuracy of the OCS is lost of the angle of rotation of the polarization plane is dependent on the Verdet constant, apart from the magnetic field strength. As temperature increases the Verdet constant decreases, so the angle of rotation …

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

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

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 …

Environmentally-friendly purchase intentions: Debunking the misconception behind apathetic consumer attitudes.

By measuring intentions to purchase, this research gives insight into environmental attitudes, pressures to purchase environmentally friendly apparel, factors that inhibit environmentally friendly apparel purchasing, awareness of environmentally friendly apparel purchase options, and marketing insight into the eco-friendly consumer. The theory of planned behavior (TPB) was used to assess consumer purchasing intentions for environmentally friendly apparel. The TPB consists of a three-pronged measurement: individual attitudes, subjective norms, and perceived behavioral control. Individual attitudes were gauged on three dimensions which included environmental attitudes, demographic patterns, and environmentally friendly apparel purchase intentions. Subjective norms involve social pressure to engage in eco-friendly behavior, perceived individual environmental impact, and desire for uniqueness in dress. Finally, perceived behavioral control was studied through previous environmentally friendly apparel purchases, accessibility of environmentally friendly apparel purchase options, and cost of environmentally friendly apparel. The results revealed that individual environmental attitudes, social pressure to behave environmentally friendly, perceived individual environmental impact, desire for uniqueness in dress, past environmentally friendly apparel purchases, accessibility of environmentally friendly apparel purchase options, and cost of environmentally friendly apparel all have an impact on intentions to purchase environmentally friendly apparel. The variable with the strongest relationship to intentions was social pressure. A demographic profile …
