Clarinet Performance Practices For Alberto Ginastera's "Variaciones Concertantes": Solutions For Orchestral Auditions And Performances, Thomas James Kmiecik

UNLV Theses, Dissertations, Professional Papers, and Capstones

The principal clarinet part of Alberto Ginastera's Variaciones concertantes (1953) requires the performer to execute a number of exposed passages that are considered impractical by many clarinetists as published. The Boosey & Hawkes edition of Variaciones concertantes was published for the B-flat clarinet. On account of this clarinet choice, the part exceeds the traditional upper range of the instrument in the third variation (Variazione in modo di Scherzo per Clarinetto ). Moreover, it requires very awkward fingering patterns in passages because they are written in the Phrygian mode of C-sharp. To avoid some of these technical obstacles, many professional …

The Pedagogy Of Pornography: What Popular Pornography On The Internet Teaches Us About Aggression And Consent, Anthony Springrt Jr.

UNLV Theses, Dissertations, Professional Papers, and Capstones

Pornography remains a highly discussed and hotly debated topic within the academy and popular culture. Despite declining revenues for pornographic content, the proliferation of the Internet makes pornography easier to access than ever before. This study examines aggression and consent in popular pornography on the Internet. One hundred scenes across five highly trafficked Web sites’ “most viewed” sections were selected for analysis. Consistent with existing research literature, women were overwhelmingly the targets of aggressive acts and typically expressed consensual reactions to acts of aggression. The results are examined within the context of social learning theory to posit what ideas and …

Challenges In Researching The Relationship Between Delinquency And Family Dynamics In Juvenile Sex Offenders, Dio Kevin Turner Ii

UNLV Theses, Dissertations, Professional Papers, and Capstones

Recently developed treatment approaches on juvenile sex offenders include the offenders and their families. These approaches have some empirical support; however, little research attempts to link family dynamics and child abuse with juvenile re-offending. This study attempted to examine the family dynamics from the juveniles’ perspective. The Family Assessment Measure (FAM-III), Parental Bonding Instrument (PBI), Self Reported Delinquency measure (SRD), and Childhood Trauma Questionnaire - Short Form (CTQ-SF) were used to assess family dynamics, parenting style, delinquency and childhood maltreatment, respectively. Problems with recruitment resulted in too few participants (N=6) to conduct meaningful statistical analyses. Participant responses suggested elevated impression …

Factors Which Influence The Use Of Active Learning Strategies By Nursing Faculty, Deborah Lowell Shindell

UNLV Theses, Dissertations, Professional Papers, and Capstones

Nursing education is facing a crisis. Anachronistic teaching methods are no longer keeping up with the needs of new graduates entering practice. Despite a body of knowledge which supports the use of active learning in higher education, nursing faculty continue to rely on lecture as their primary pedagogical approach. Previous study of the use of research products in clinical nursing practice identified systematic factors such as characteristics of the communication of research findings and characteristics of the organization form the greatest barrier to use. This study discovers if these same barriers face nursing educators.

Fourth and fifth grade students with reading disabilities participated in twice-weekly literature discussions, 30- to-60 minutes each, for 12 weeks. The students attended a Title I school and most were Hispanic males. Together, they read and discussed five postmodern picturebooks. The purpose of the study was to understand (a) reader responses to the illustrations, text, and postmodern features of the books, and (b) the individual reader’s response habits. Situated within a sociocultural frame, the theories guiding this study pertained to language …

Sensing And Transmission Strategies In Wireless Cognitive Radio Systems, Babak Abbasi Bastami

UNLV Theses, Dissertations, Professional Papers, and Capstones

The main challenge in any cognitive radio system is to maximize secondary users throughput while limiting interference imposed on licensed users. In this regard, finding the optimal sensing and transmission timing strategies and accurate sensing techniques are of great importance in a cognitive radio network.

In this thesis, we study a sensing-transmission scheme for secondary user in a cognitive radio system where the secondary user senses every primary channel independently and transmits a signal for a fixed duration if it finds the channel empty and stays idle for another fixed duration if it senses the channel busy. We obtain optimal …

Comparative And Critical Analysis: The Roles Of Civic And Traditional Journalism, Kendle Walters

UNLV Theses, Dissertations, Professional Papers, and Capstones

This research contains a comparative and critical analysis of both civic and traditional journalism and the practices associated with the two models. In depth interviews were conducted with a total of nine respondents to explore their perspectives on the topic. Purposive sampling was employed to ensure the sample consisted solely of journalists and former journalists. From the data emerged five primary themes: Objectivity, Journalists as Problem Solvers, Confusion with the Term Civic Journalism, Journalists' Encouragement of Political Discourse and Deliberation, and Dedication to Traditional Journalism. Respondents overwhelmingly supported the notion of traditional journalism as the dominant model. There was support …

Identifying Effort Estimation Factors For Corrective Maintenance In Object-Oriented Systems, Michael J. Lee

UNLV Theses, Dissertations, Professional Papers, and Capstones

This research identifies factors that impact software maintenance effort by exploring the decision-making process of expert estimators of corrective maintenance projects by using qualitative methods to identify the factors that they use in deriving estimates. We implement a technique called causal mapping, which allows us to identify the cognitive links between the information that estimators use, and the estimates that they produce based on that information. Results suggest that a total of 17 factors may be relevant for corrective maintenance effort estimation, covering constructs related to developers, code, defects, and environment. When these factors are rank-ordered, they demonstrate that some …

Methodological Quality Of Quantitative Nursing Lesbian, Gay, Bisexual, And Transgender Research From 2000 To 2010, Michael Johnson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lesbian, gay, bisexual, and transgender (LGBT) people constitute one of the largest underserved populations in any nursing setting. Despite the large LGBT populations, very little nursing research has been conducted on these populations. Nurse researchers have recommended that nursing researchers end the silence on LGBT research. To accomplish this, the methodological rigor of LGBT nursing research must be evaluated and improved upon. Currently, no literature examines the methodological quality of quantitative nursing LGBT research. Using a cross-sectional design, it was the purpose of this study to evaluate the methodological quality of quantitative nursing LGBT research from 2000 to 2010 using …

The Impact Of World War Ii On Women's Fashion In The United States And Britain, Meghann Mason

UNLV Theses, Dissertations, Professional Papers, and Capstones

World War II (hereafter referred to as WWII) is a fascinating era in fashion, society, and politics. The fashion of the era was truly representative of the events happening in the world in a most visible way. This era made indelible marks on future designers and the science of fashion as the world knows it. Fashion and costume design were influenced and changed due to the many limitations presented and imposed by WWII. WWII represents a great marker of change socially, technologically, economically, and politically. While it affected the entire world, the main focus of this thesis will explore the …

Development Of A Simulation Tool For Analysis Of Freeway Crashes Due To Cell Phone Usage, Sourabh Sriom

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research shows that drivers are susceptible to numerous distractions while driving which can be held responsible as the reason of a crash. Usage of cell phones, i.e. talking or texting while driving is considered one of the prominent distractions which causes a crash. This dissertation aims to study the number of crashes occurring on the freeways and their relation with the drivers of these cars using cell phones while they are driving. Since crashes occur relatively less frequently, the study of crashes is done using what is called the "rare event" theory. Java based simulations are done to model a …

Korean Mask-Dance And Aristotle's Poetics, Teayong Pakr

UNLV Theses, Dissertations, Professional Papers, and Capstones

Korean mask-dance is the traditional theatre of Korea. It was formerly the country's most well-known form of drama among traditional theatrical entertainments. This study explores the theatrical structure of Korean mask-dance as well as its historical background.

The rise of Korean mask-dance may be traced back to the shamanistic village ritual which gradually became similar to the extant form after absorbing aspects of the Buddhism festival through the Goryeo Dynasty, which lasted from 918-1392). During the Joseon Dynasty (1392-1910), the mask-dance had acquired its basic form with aspects of professional theatrical entertainment. The mask-dances have been performed during traditional holidays …

Fall Prevention Training And Its Impact To Southern Nevada Construction Workers, Vedaspati Joshi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Death and injury from falls are a long-standing and continuing problem in construction, responsible for at least a third of the construction deaths in the U.S. from 2004 to 2007. Each of those years, Nevada has exceeded the national percentage. Although 29 CFR 1926.503 sets forth Occupational Safety and Health Administration (OSHA)'s requirements that construction employers train employees exposed to fall hazards and document such training, the incidence of deaths and injuries from falls are an indicator that this training was not provided or else was not effective.

Conventional fall protection training is more narrowly focused on recognizing fall hazards …

Scaling Laws Of Key Predistribution Protocols In Wireless Sensor Networks, Wenjun Gu, Sriram Chellappan, Xiaole Bai, Honggang Wang

Computer Science Faculty Research & Creative Works

Many key predistribution (KP) protocols have been proposed and are well accepted in randomly deployed wireless sensor networks (WSNs). Being distributed and localized, they are perceived to be scalable as node density and network dimension increase. While it is true in terms of communication/computation overhead, their scalability in terms of security performance is unclear. in this paper, we conduct a detailed study on this issue. in particular, we define a new metric called Resilient Connectivity (RC) to quantify security performance in WSNs. We then conduct a detailed analytical investigation on how KP protocols scale with respect to node density and …

Dynamic Partial Reconfiguration For Pipelined Digital Systems— A Case Study Using A Color Space Conversion Engine, Ryan Toukatly

Theses

In digital hardware design, reconfigurable devices such as Field Programmable Gate Arrays (FPGAs) allow for a unique feature called partial reconfiguration PR). This refers to the reprogramming of a subset of the reconfigurable logic during active operation. PR allows multiple hardware blocks to be consolidated into a single partition, which can be reprogrammed at run-time as desired. This may reduce the logic circuit (and silicon area) requirements and greatly extend functionality. Furthermore, dynamic partial reconfiguration (DPR) refers to PR that does not halt the system during reprogramming. This allows for configuration to overlap with normal processing, potentially achieving better system …

Specters In The Archive: Faculty Digital Image Collections And The Problems Of Invisibility, Joan E. Beaudoin

School of Information Sciences Faculty Research Publications

This paper argues that the devaluation of visual information in favor of textual information will result in a loss of visual information in a digital form that has personal, institutional and cultural ramifications. Framing this discussion is a study of the digital preservation practices among two faculty user groups, archaeologists and art historians. The study examined the faculty users’ knowledge, perception, emotions and processes surrounding the digital images they had created and, or collected to support their professional activities. What was discovered is a worrisome situation where an important part of the cultural record is at serious risk of being …

Production And Fate Of Transparent Exopolymer Particles In The Ocean, Oliver Wurl, Lisa Miller, Svein Vagle

OES Faculty Publications

The production and fate of transparent exopolymer particles (TEP) have been investigated in various oceanic regions (tropical, temperate, and polar), from the sea surface microlayer (SML) to the deep ocean. Accumulation of TEP within the mixed layer was observed even in the absence of phytoplankton blooms, indicating abiotic processes are important in TEP production. The abiotic TEP aggregation rates measured in the tropical and temperate North Pacific and the Arctic Ocean averaged between 8 and 12 μmol C L^-1 d-¹. Depth profiles from under sea ice in the Arctic revealed the highest TEP concentrations, potentially released by …

Including The Excluded: Communitarian Paths To Cosmopolitanism, Eduard Jordaan

Research Collection School of Social Sciences

Cosmopolitanism is frequently criticised for overlooking the situatedness of morality and the importance of solidarity in their aspiration to global justice. A number of thinkers take these criticisms seriously and pursue ‘a communitarian path to cosmopolitanism’. Four such approaches are considered. All four view morality and justice as grounded in a specific social setting and hold that justice is more likely to result if there is some ‘we-feeling’ among people, but are simultaneously committed to expanding the realm of justice and moral concern to beyond national boundaries. To enable the theorisation of an expanded realm of situated justice and moral …

Barriers To And Facilitators Of Latino Parent Involvement: One Georgia District's Perspective, Lakshmi Subramaniam

College of Graduate Studies: Theses & Dissertations

The face of America's school is changing bringing in students from all over the world, predominantly Spanish speaking students from Mexico and Central and South America. Parents of these students are trying to balance the various challenges that moving to a new country can bring, including fostering success in school for their children. Oftentimes, their jobs, their immigration status, or their lack of education prevent them from speaking out and sharing their experiences. Many of these families are in areas of the country where immigration issues are relatively new. Unfortunately, statistics on academic achievement and drop-out rates for these Latino …

Classwide Functional Analysis And Comparison Of Function-Based Interventions With Preschoolers, Veena Yamasani Poole

Dissertations

Few studies have used experimental functional analysis procedures and function-based treatments using the class as a unit of analysis. Two kindergarten classrooms, one Head Start classroom and their teachers participated in the study. Both the assessment and intervention included teacher-implemented functional analyses and intervention using the class as the unit of analysis. Functional assessment procedures included a direct-descriptive screening observation, teacher interviews, and functional analyses. Assessment data were used to develop function-based interventions. An alternating treatment design with a verification phase was used to evaluate treatment effects. Function-based interventions, specifically, differential reinforcement of appropriate behaviors (DRA), resulted in decreases in …

Principals’ Perceptions Of Readiness For Their Evolving Roles In High-Stakes Environments, Angela Marie Huff

Dissertations

Principals are leading schools during an evolving time where preparation may not have prepared principals fully for the task of school leadership. The past decade has revealed an escalation in the disapproval of principal preparation programs and participants in these programs insist that these schools be held accountable (Levine, 2005). However, in revamping preparation programs, one must focus on student selection, curriculum and course content, pedagogical strategies, internships, and field experiences (Orr, 2006). Some have suggested that the job of principal may have become impossible for all but a few super leaders (Lashway, 2003). The requirements of the job may …

A Historical Perspective Of Testing And Assessment Including The Impact Of Summative And Formative Assessment On Student Achievement, Carole Sanger Brink

Dissertations

In 2007, Georgia developed a comprehensive framework to define what students need to know. One component of this framework emphasizes the use of both formative and summative assessments as part of an integral and specific component of the teachers' performance evaluation. Georgia administers the Criterion-Referenced Competency Test (CRCT) to every elementary student in Grades 1 though 8. Before 2008, the state tested eighth-grade students on a quality core curriculum. In 2008, the state began testing students on a Georgia Performance Standard curriculum. A direct comparison of the curriculum change should have contained items to test both curriculums. However, this was …
