Confronting Convergence:  Are Higher Education Administrators Using a Strategic Planning Approach to Mass Communication Curriculum Convergence? (open access)

Confronting Convergence: Are Higher Education Administrators Using a Strategic Planning Approach to Mass Communication Curriculum Convergence?

Professors in mass communications departments of higher education institutions continue to search for the best way to prepare graduates for the ever-changing world of print, broadcast, and online media. Business administration theories have long been used in other areas, including education. While some application of strategic planning has been documented with regards to education, there is not much to reference in this area. The study investigated the use of strategic planning in developing a course of action for curriculum convergence in mass communication programs. The study used a purposive sample to determine if administrators are utilizing this method as a part of curriculum convergence. The results indicated a use of this method among institutions involved in curriculum convergence.

Excerpts From the Eva Crane Field Diary: Stories (open access)

Excerpts From the Eva Crane Field Diary: Stories

Male or female, young or old, the characters of this collection inhabit a liminal space of trauma and social dislocation in which elements of the real and fabulous coexist in equal measure. The ghosts that populate the stories are as much the ghosts of the living, as they are the ghosts of the dead. They represent individual conscience and an inescapable connection to the past.

Does the Provision of an Intensive and Highly Focused Indirect Corrective Feedback Lead to Accuracy? (open access)

Does the Provision of an Intensive and Highly Focused Indirect Corrective Feedback Lead to Accuracy?

This thesis imparts the outcomes of a seven-week long quasi-experimental study that explored whether or not L2 learners who received intensive and highly focused indirect feedback on one type of treatable error - either the third person singular -s, plural endings -s, or definite article the - eventually become more accurate in the post-test as compared to a control group that did not. The paired-samples t-test comparing the pre-test and post-test scores of both groups demonstrates that the experimental group did no better than the control group after they received indirect corrective feedback. The independent samples t-test measuring the experimental and control group's accuracy shows no significant difference between the two groups. Effect sizes calculated, however, do indicate that, had the sample sizes been bigger, both groups would have eventually become more accurate in the errors targeted, although this would not have been because of the indirect feedback.

A Study of Anti-collision Multi-tag Identification Algorithms for Passive RFID Systems (open access)

A Study of Anti-collision Multi-tag Identification Algorithms for Passive RFID Systems

The major advantages of radio frequency identification (RFID) technology over barcodes are that the RFID-tagged objects do not require to be in line-of-sight with the reader for their identification and multiple objects can be read simultaneously. But when multiple objects are read simultaneously there is always a problem of collision which reduces the efficiency of the system. This thesis presents a comprehensive study of the dynamic framed slotted ALOHA (DFSA)-based anti-collision multi-tag identification algorithms for passive RFID system. Performance of various DFSA algorithms is compared through extensive simulation results. In addition, a number of simple performance improvement techniques have also been investigated in this thesis, including improved estimation techniques for the number of tags in each read cycle and a low-complexity heuristic stopping criterion that can be easily implemented in the practical system.

Speaking up: Applying the Theory of Planned Behavior to Bystander Intervention in Racism (open access)

Speaking up: Applying the Theory of Planned Behavior to Bystander Intervention in Racism

Because racism remains a significant issue in society, and many victims of racism do not speak up for themselves when faced with racism, it is important to explore how witnesses to racist events may react and intervene upon observing racism toward others. Thus, the current study explored how participants (bystanders) reacted verbally to racist comments made by a confederate during a partner activity, as well as how participants discussed their reactions in post-interviews. Forty college students participated in the study, and three of the participants verbally intervened upon hearing the racist statements. Ajzen's theory of planned behavior was utilized as a framework, and examination of the results indicated that components of the theory as well as social constructions of racism and appropriateness of intervention behaviors affect intervention outcomes. Theoretical, methodological, and practical implications, as well as suggestions for future research are included.

Comparison of Heteranthera Dubia (Jacq.) MacM.-associated Macroinvertebrates Between Georgraphical Regions in the United States (open access)

Comparison of Heteranthera Dubia (Jacq.) MacM.-associated Macroinvertebrates Between Georgraphical Regions in the United States

Macroinvertebrates associated with the aquatic plant, water stargrass (Heteranthera dubia), were sampled from 12 waterbodies in four regions of the United States from June to August 2005. Taxa richness, evenness, and diversity were lowest in the Lower Midwest (LMW) region, and higher in Northern sites, especially the Upper Midwest (UMW), and Northeast (NE). While relative abundance varied from site to site and region to region, utilization of the plant by functional groups remained fairly constant. Collector-gatherers consistently comprised the largest portion of invertebrates sampled. The shredder/ herbivore functional group comprised an average of 17 % of total groups. Through an exhaustive literature review, it was found that shredder/ herbivores of water stargrass have not been reported in the literature. Because of this, the herbivore group was analyzed separately and consisted of 2,383 specimens representing 23 species. The most common groups were Rhopalosiphum sp., Nectopsyche spp. and chironomids. No differences were found in herbivore diversity or evenness between sampling regions, but species richness was significantly different.

Modulation of the Coelomic Fluid Protein Profile in the Earthworm, Lumbricus Terrestris, After Exposure to Copper as Copper Sulfate (open access)

Modulation of the Coelomic Fluid Protein Profile in the Earthworm, Lumbricus Terrestris, After Exposure to Copper as Copper Sulfate

Proteomic techniques were used to analyze the protein profile of earthworm, Lumbricus terrestris, coelomic fluid collected by either whole body dissection method or the coelomic cavity puncture method. Data demonstrated that collection of coelomic fluid using the coelomic cavity puncture method protocol resulted in a 32% reduction, 377 +/- 4.5 vs 253+/- 19.9 (p=0.0007), in the number of individual proteins. It was determined that the coelomic cavity puncture method yielded a "cleaner" preparation, one less contaminated with extraneous proteins from intestinal tissue, gut contents, and body wall materials. This protocol was used in all later studies. The same proteomic techniques were used to evaluate the effects that exposure to Cu (1.0 μg/cm2) as CuSO4 had on the earthworm coelomic fluid profile. Comparison of protein profile from exposed earthworms demonstrated a significant reduction in the number of proteins expressed (184 ± 2.64 vs 253 ±19.9 p=0.0192) when compared to control organisms. Cu exposure also resulted in a modulation of the protein profile with treated earthworms expressing 47 new proteins that were not identified in unexposed worm coelomic fluid. Additionally, 116 proteins found in coelomic fluid collected from normal worms were absent in Cu exposed organisms. Finally, 137 proteins were conserved or …

Teaching Points in Comparing the Great Depression to the 2008-2009 Recession in the United States (open access)

Teaching Points in Comparing the Great Depression to the 2008-2009 Recession in the United States

For an introductory macroeconomics course, the discussion of historical relevance helps foster important learning connections. By comparing the Great Depression to the 2008-2009 recession, a macroeconomics instructor can provide students with connections to history. This paper discusses the major causes of each recession, major fiscal policy and monetary policy decisions of both recessions, and the respective relevance in teaching the relationship of each policy to gross domestic product. The teaching points addressed in this paper are directed towards an introductory college-level macroeconomics course, incorporating a variety of theories from historical and economic writers and data from government and central bank sources. A lesson plan is included in an appendix to assist the instructor in implementing the material.

Adaptive Advantages of Carotenoid Pigments in Alpine and Subalpine Copepod Responses to Polycyclic Aromatic Hydrocarbon Induced Phototoxicity (open access)

Adaptive Advantages of Carotenoid Pigments in Alpine and Subalpine Copepod Responses to Polycyclic Aromatic Hydrocarbon Induced Phototoxicity

Alpine zooplankton are exposed to a variety of stressors in their natural environment including ultraviolet radiation. Physiological coping mechanisms such as the accumulation of photoprotective compounds provide these zooplankton protection from many of these stressors. Elevated levels of carotenoid compounds such as astaxanthin have been shown to help zooplankton survive longer when exposed to ultraviolet radiation presumably due to the strong antioxidant properties of carotenoid compounds. This antioxidant capacity is important because it may ameliorate natural and anthropogenic stressor-induced oxidative stress. While previous researchers have shown carotenoid compounds impart increased resistance to ultraviolet radiation in populations of zooplankton, little work has focused on the toxicological implications of PAH induced phototoxicity on zooplankton containing high levels of carotenoid compounds. This thesis discusses research studying the role that carotenoid compounds play in reducing PAH induced phototoxicity. By sampling different lakes at elevations ranging from 9,500' to 12,700' in the front range of the Colorado Rocky Mountains, copepod populations containing different levels of carotenoid compounds were obtained. These populations were then challenged with fluoranthene and ultraviolet radiation. Results discussed include differences in survival and levels of lipid peroxidation among populations exhibiting different levels of carotenoid compounds, and the toxicological and ecological implications of …

"Being" a Stickist:  A Phenomenological Consideration of "Dwelling" in a Virtual Music Scene (open access)

"Being" a Stickist: A Phenomenological Consideration of "Dwelling" in a Virtual Music Scene

Musical instruments are not static, unchanging objects. They are, instead, things that materially evolve in symmetry with human practices. Alterations to an instrument's design often attend to its ergonomic or expressive capacity, but sometimes an innovator causes an entirely new instrument to arise. One such instrument is the Chapman Stick. This instrument's history is closely intertwined with global currents that have evolved into virtual, online scenes. Virtuality obfuscates embodiment, but the Stick's world, like any instrument's, is optimally related in intercorporeal exchanges. Stickists circumvent real and virtual obstacles to engage the Stick world. Using an organology informed by the work of Heidegger and Merleau-Ponty, this study examines how the Chapman Stick, as a material "thing," speaks in and through a virtual, representational environment.

Routine Leisure Activities and Adolescent Marijuana Use: Moderating Effects of Family Structure (open access)

Routine Leisure Activities and Adolescent Marijuana Use: Moderating Effects of Family Structure

How adolescents spend their time is a crucial predictor of their engagement in delinquency. Activities with peers away from direct supervision of adults are of concern as more opportunities and motivation to use marijuana exist in such situations. However, adolescents may vary in their propensity to use marijuana when faced the opportunity. Especially adolescents living with a single parent may have a higher propensity compared to those from two-parent households to use marijuana due to reduced parental monitoring and increased peer attachment. This thesis investigates the moderating effects of family structure on the routine leisure activities and adolescent marijuana use relationship, using data from Monitoring the Future Study 2007, 12th Grade Survey. The results provide partial support for the moderating effects.

L'emploi variable des signes diacritiques dans le français tchaté : une étude variationniste en temps apparent .

After providing an historical overview of the French spelling system and orthographic variation, this study analyzes selected internal (i.e., linguistic) factors and one external (i.e., social) factor that can influence the use of diacritics in online French-language chat sessions. From a corpus of synchronous computer-mediated communication, 3,855 tokens of graphemes capable of bearing diacritics were coded with the following scheme: Letter, Diacritic, Grapheme (i.e., Letter and Diacritic combined), Date of Participation, and Age Group of Participant. A multivariate (VARBRUL) analysis determined that Grapheme exerts the most influence on variation.

Effects of Suspended Multi-Walled Carbon Nanotubes on Daphnid Growth and Reproduction (open access)

Effects of Suspended Multi-Walled Carbon Nanotubes on Daphnid Growth and Reproduction

Multi-walled carbon nanotube aggregates can be suspended in the aqueous phase by natural organic matter. These aggregates are ingested by filter feeding zooplankton. Ingested aggregates result in decreased growth and decreased reproduction. These effects may be caused by reduction in energy input from normal feeding behavior. pH alters natural organic matter structure through changes in electrostatic repulsion. Altered natural organic matter structure changes multi-walled carbon nanotube aggregate size. This size variation with variation in pH is significant, but not large enough a change in size to alter toxicity, as the aggregate size range remains well within the particle size selection of the organisms.

Tracing the Path of Sustainable Development through Major International Conferences: A Brief History and Overview of Sustainable Development 1964-2002 (open access)

Tracing the Path of Sustainable Development through Major International Conferences: A Brief History and Overview of Sustainable Development 1964-2002

Starting with the idea that unsustainable practices contribute to issues of social justice and poverty as much as to ecological issues. Chapter 1 traces the origins of the terms sustainable and development individually to see how it is that they came together. Chapter 2 traces the major international conferences and documents and their use of the terms sustainable development. Chapter 3 takes a phenomenology approach to get a bit deeper into sustainable development. I examine the most commonly cited definition of sustainable development as well as a broader definition of sustainable development as a process of change. Chapter 4 examines the field of environmental ethics and argues that constant debates over value distract policy makers from the central question of what morally motivates people to support environmental ethics views. Chapter 5 examines the institution and regime building process, and the conclusion offers three questions to measure our progress.

Stretching the Flexible Myosin II Subfragment Using the Novel Gravitational Force Spectroscope, and the Uncoiling of S2 (open access)

Stretching the Flexible Myosin II Subfragment Using the Novel Gravitational Force Spectroscope, and the Uncoiling of S2

Familial Hypertrophic cardiomyopathy (HCM) causes ventricle walls to thicken and often leads to sudden death especially in adults. Mutations in the subfragment 2 (S2) of β-cardiac myosin are implicated in the genetic disorder. This S2 region is a coiled-coil rod region resulting from the dimeric form of myosin II. It has been proposed that an elastic quality allows normal S2 to absorb force during the powerstroke according to the sliding filament model. To test the flexibility of single molecules of S2 against levels of physiological force, the Gravitational Force Spectrometer (GFS) is being developed. This novel system employs a standard microscope on an equatorial mount that allows the spectrometer to be rotated freely in space. Stationary glass beads are attached to a microscope slide where the molecule is tethered between the stationary bead and a smaller mobile bead. The GFS is oriented so that the force of gravity can act on the mobile bead and so impart a small force to the tethered subfragment. Additionally, a video system in conjunction with ImageJ software makes a distance measurement of the molecule possible with a resolution of around 11 nm. The S2 can be stretched parallel or perpendicular to the coiled coil …

Self-Objectification and Sport Participation: Do the Gendered Makeup and Competitive Level of the Team Matter? (open access)

Self-Objectification and Sport Participation: Do the Gendered Makeup and Competitive Level of the Team Matter?

The purposes of this study were to (a) investigate differences in self-objectification, self-surveillance, body shame, and flow among female athletes on all-women's and coed ultimate frisbee teams at different competitive levels, and (b) examine the objectification theory model across groups. Participants (n = 112) completed online surveys including a demographic questionnaire, trait and state versions of the Self-Objectification Questionnaire, Body Surveillance and Body Shame subscales of the Objectified Body Consciousness Scale, and the Flow State Scale. No differences in self-objectification, self-surveillance, or body shame were found, although highly competitive athletes experienced more flow than lower competitive teams. Relationships were found between self-objectification, self-surveillance, and body shame, but not for flow, partially supporting the objectification theory model.

Using Geographic Information Systems for the Functional Assessment of Texas Coastal Prairie Freshwater Wetlands Around Galveston Bay (open access)

Using Geographic Information Systems for the Functional Assessment of Texas Coastal Prairie Freshwater Wetlands Around Galveston Bay

The objective of this study was to deploy a conceptual framework developed by M. Forbes using a geographic information system (GIS) approach to assess the functionality of wetlands in the Galveston Bay Area of Texas. This study utilized geospatial datasets which included National Wetland Inventory maps (NWI), LiDAR data, National Agriculture Imagery Program (NAIP) imagery and USGS National Land Cover data to assess the capacity of wetlands to store surface water and remove pollutants, including nitrogen, phosphorus, heavy metals, and organic compounds. The use of LiDAR to characterize the hydrogeomorphic characteristics of wetlands is a key contribution of this study to the science of wetland functional assessment. LiDAR data was used to estimate volumes for the 7,370 wetlands and delineate catchments for over 4,000 wetlands, located outside the 100-yr floodplain, within a 2,075 square mile area around Galveston Bay. Results from this study suggest that coastal prairie freshwater wetlands typically have a moderate capacity to store surface water from precipitation events, remove ammonium, and retain phosphorus and heavy metals and tend to have a high capacity for removing nitrate and retainremove organic compounds. The results serve as a valuable survey instrument for increasing the understanding of coastal prairie freshwater wetlands …

Fractus I for Trumpet in C and Electronic Sound: A Critical Examination of the Compositional Process

Fractus I is a composition for trumpet in C and live electronic sound. The electronics were primarily created using SuperCollider, an environment and programming language for real time audio synthesis. This project investigates SuperCollider's pattern and task functionality as a means of supporting and enriching the compositional process. Fractus I develops several different code architectures in order to randomize as well as synchronize various musical elements. The piece exploits SuperCollider as both an audio synthesis tool and a performance conduit. Additionally, the nature of SuperCollider's patterns and tasks influences the form and content of the composition. The project underscores SuperCollider as a powerful, versatile and open-ended tool for musical composition and examines future directions and improvements.

Cracking the Closed Society: James W. Silver and the Civil Rights Movement in Mississippi (open access)

Cracking the Closed Society: James W. Silver and the Civil Rights Movement in Mississippi

This thesis examines the life of James Wesley Silver, a professor of history at the University of Mississippi for twenty-six years and author of Mississippi: The Closed Society, a scathing attack on the Magnolia State's history of racial oppression. In 1962, Silver witnessed the campus riot resulting from James Meredith's enrollment as the first black student at the state's hallowed public university and claims this was the catalyst for writing his book. However, by examining James Silver's personal and professional activities and comparing them with the political, cultural, and social events taking place concurrently, this paper demonstrates that his entire life, the gamut of his experiences, culminated in the creation of his own rebel yell, Mississippi: The Closed Society. Chapter 1 establishes Silver's environment by exploring the history and sociology of the South during the years of his residency. Chapter 2 discusses Silver's background and early years, culminating with his appointment as a faculty member of the University of Mississippi in 1936. Chapter 3 reveals Silver's personal and professional life during the 1940s, as well as the era's notable historical events. The decade of the 1950s is discussed in chapter 4, particularly the civil rights movement, Silver's response to these …

Effect of Fluorine and Hydrogen Radical Species on Modified Oxidized Ni(pt)si (open access)

Effect of Fluorine and Hydrogen Radical Species on Modified Oxidized Ni(pt)si

NiSi is an attractive material in the production of CMOS devices. The problem with the utilization of NiSi, is that there is no proper method of cleaning the oxide on the surface. Sputtering is the most common method used for the cleaning, but it has its own complications. Dry cleaning methods include the reactions with radicals and these processes are not well understood and are the focus of the project. Dissociated NF3 and NH3 were used as an alternative and XPS is the technique to analyze the reactions of atomic fluorine and nitrogen with the oxide on the surface. A thermal cracker was used to dissociate the NF3 and NH3 into NFx+F and NHx+H. There was a formation of a NiF2 layer on top of the oxide and there was no evidence of nitrogen on the surface indicating that the fluorine and hydrogen are the reacting species. XPS spectra, however, indicate that the substrate SiO2 layer is not removed by the dissociated NF3 and NiF2 growth process. The NiF2 over layer can be reduced to metallic Ni by reacting with dissociated NH3 at room temperature. The atomic hydrogen from dissociated ammonia reduces the NiF2 but it was determined that the …

This study partially replicates and re-explores specific dimensions of a textbook analysis of the presentation and use of specific grammatical elements and sociolinguistic variants in textbooks published in the United States for learners of French. Authenticity is situated as a central construct in the analysis of interrogatives, relative pronouns, and the negative particle ne in selected textbooks and ancillary materials. The findings reveal that little progress has been made over the past twenty years in integrating authentic representations of discourse into French-as-a-foreign-language textbooks.

Discovery of Resources and Conflict in the Interstate System, 1816-2001 (open access)

Discovery of Resources and Conflict in the Interstate System, 1816-2001

This study tests a theory detailing the increased likelihood of conflict following an initial resource discovery in the discovering nation and its region. A survey of prior literature shows a multitude of prior research concerning resources and nations' willingness to initiate conflict over those resources, but this prior research lacks any study concerning the effects of the discovery of resources on interstate conflict. The theory discusses the increased likelihood of conflict in the discovering nation as both target and initiator. It further looks at the increased chance of conflict in the discoverer's region due to security dilemmas and proxy wars. The results show strong support for the theory, suggesting nations making new resource discoveries must take extra care to avoid conflict.
