Magma Chamber Processes At Mutnovsky Volcano, Russia, Kelly L. Robertson

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation is composed of two manuscripts about the evolution of Mutnovsky Volcano in Kamchatka, Russia. Mutnovsky has been active for the past approximately 80,000 years, during which there was the formation and subsequent eruption of four major stratocones. These four eruptive centers, named Mutnovsky I, II, III, and IV from oldest to youngest, have a range of erupted product compositions from basalt to dacite. The first major goal of this project was to investigate the melt source for Mutnovsky. Whole rock trace element and Nd, Sr, and Pb isotopic data were used to determine that the melt source was …

Conversion Of English Characters Into Braille Using Neural Network, Mohammed Y., Ahmed G. Mohammed

Iraqi Journal of Computers, Communications, Control and Systems Engineering

The Braille system is a method that is widely used by blind people to read and write. Braille generally consists of cells of raised dots arranged in a grid. The presence or absence of dots can be sensed by the blind people’s fingertips to give them the coding for the symbol. The electronic reVolution is changing the way Braille is produced, stored and retrieved, making it easier to use in the work place. All kinds of materials can be put into Braille, from bank statements, bus timetables, maps to music. But it is still difficult to produce an error-free Braille …

Nursing Students' Lived Experiences Surrounding Medication Administration, Sally Nan Morgan Phd

Dissertations

Medication errors are abounding and the complexity of medication administration creates an environment where health care providers are at risk for making errors. This environment includes nursing students learning medication administration. Coupled with a rigid, protocol-driven pedagogy, nursing students may be placed in a learning experience counterproductive to accuracy. Previous studies have focused on causes and perceptions of medication errors looking for the delineation between safe and unsafe practice. In doing so, past research may have narrowed the path of discovery needed to diminish medication errors. In addition, research regarding the lived experience of nursing students while they are learning …

Cultivating Readiness For Professional Learning Community Through Learning Teams In A Restructuring High School, Cassandra H. Hyacinthe

Education Doctoral

The traditional organizational structure of large comprehensive high schools: departmental divisions, teacher isolation, fragmented subcultures, student alienation, and competing group interests have undermined student and adult learning and have thwarted attempts at school reform. Professional learning communities (PLCs) are a promising strategy for advancing student achievement and school reform. Schools with strong PLCs foster a collaborative culture, focus on learning, promote shared responsibility, and pursue results-oriented goals and assessments to ensure student academic gains. The study investigated the use of learning teams as a preliminary strategy for PLC and to inform school-wide PLC implementation in a restructuring high school. Wenger’s …

The Association Between Reading Comprehension And Prerequisite Skills For Children In Poverty, Hyo Jin Yoon

Theses and Dissertations (ETD)

The purpose of this study was to investigate the relationship between reading comprehension and the prerequisite skills typically assessed by a school based speech pathologist with a focus on children raised in poverty. Based upon previous studies, three hypotheses were developed. First, children from low socioeconomic status (SES) backgrounds would not perform as well as children from the standardization sample on norm referenced language tests although the language tests would predict reading comprehension. Second, decoding would not be as good a predictor of reading comprehension for children from low SES backgrounds as it is in typically developing children from middle …

Accessing Justice: The Availability And Adequacy Of Counsel In Removal Proceedings (New York Immigrant Representation Study Report: Part 1), Peter L. Markowitz, Jojo Annobil, Stacy Caplow, Peter V.Z Cobb, Nancy Morawetz, Oren Root, Claudia Slovinsky, Zhifen Cheng, Lindsay Nash

Cardozo Law Review

The article addresses the immigrant representation crisis in U.S. immigration courts, highlighting a severe shortage of competent legal representation for individuals in removal proceedings. This crisis is marked by both a lack of quantity and quality of representation, exacerbated by rising deportation rates, detention practices, and resource constraints faced by removal defense providers (RDPs). The study underscores the critical role of legal representation in achieving successful outcomes, with stark disparities in success rates between represented and unrepresented individuals. It advocates for systemic solutions, including expanded funding, improved coordination among providers, and policy reforms to ensure fair and competent representation for …

Considering The Scope Of Advisal Duties Under Padilla, Lindsay C. Nash

Cardozo Law Review

In Padilla v. Kentucky, the Supreme Court recognized the complexity and severity of immigration penalties triggered by criminal convictions and held that defense attorneys are obligated to advise clients of such consequences. In so doing, the Court explained that specific advice is required when a consequence is clear; at the same time, it acknowledged it is not always possible to ascertain the consequences of a criminal disposition and, when that is the case, counsel's duty is more limited. The Court did not, however, elaborate on the circumstances in which the duty might be limited or explain what advice defense …

Examining The Relationships Between Acculturation Orientations, Perceived And Actual Norms, And Drinking Behaviors Of Short-Term American Sojourners In Foreign Environments, Eric R. Pedersen, Rick A. Cruz, Joseph W. Labrie, Justin F. Hummer

Heads Up!

As little research has examined factors influencing increased and heavy drinking behavior among American sojourners abroad, this study was designed to examine how acculturation orientations (i.e., separation versus assimilation), host country per capita drinking rates, and perceptions about the drinking behavior among other sojourners and natives in the host country predicted alcohol risk abroad. A sample of 216 American college students completing study abroad programs completed a pre-abroad questionnaire to document their pre-abroad drinking levels, followed by a post-return questionnaire to assess drinking while abroad, acculturation orientations and perceived norms of drinking behavior within the foreign environment. A dichotomous variable …

Comparing Greek-Affiliated Students And Student Athletes: An Examination Of The Behavior-Intention Link, Reasons For Drinking, And Alcohol-Related Consequences, Karen K. Huchting, Andrew Lac, Justin F. Hummer, Joseph W. Labrie

Heads Up!

While affiliation with Greek fraternities/sororities and intercollegiate athletic teams is associated with heavier drinking (Meilman et al., 1999), few studies have compared reasons for drinking among these groups. A sample of 1,541 students, identifying as either Greeks or athletes, completed an online survey. Athletes were significantly higher than Greeks on conformity reason for drinking. Tests of independent correlations indicated the magnitude of the past behavior to intention link was considerably stronger for Greeks. Greeks experienced significantly more social problems from drinking. Several group by gender ANOVA models found significant main effects with highest drinking rates, usually among Greek …

Unveiling Jewett's Hidden Voice: Discovering The Aborted Future Of Dunnet Landing In The Country Of The Pointed Firs, Katie Mcclelland

Masters Theses and Doctoral Dissertations

Recent scholarship addresses a deeper significance to Jewett‟s female characters than was previously attributed in canonical history. Jewett imbues her women with complexity, but intentionally avoids portraying her females as disproportionately heroic. Indeed, a pervading recurrence of abortions and otherwise lost children among the predominately female community of Dunnet Landing creates a framework of death by which to interpret the actions and motivations of Jewett‟s characters. My thesis explores the larger metaphor Jewett establishes by juxtaposing the literal abortions of her female characters and the figurative abortion of Dunnet Landing‟s future; moreover, the aborted futures of Jewett‟s female characters mirror …

Basic Astronomical Estimates, Dan Ward, Emma Sturgess, Joseph Whiteman, Laura Jenkins

The Plymouth Student Scientist

The Use Of Near Infrared Spectroscopy In Measuring Haemodynamic Response Of The Primary Visual Cortex To A Visual Bullseye Stimulus With Various Spatial And Temporal Frequencies, Luke Perkins

The Plymouth Student Scientist

The effects of spatial and temporal frequencies of a visual, sinusoidal bullseye stimulus on haemodynamic responses in V1 were investigated using Near-Infrared Spectroscopy. Eight psychology undergraduates viewed a reversing bullseye pattern with differing spatial and temporal frequencies and haemodynamic responses in V1 were measured. It was found that optimum responses were recorded when the spatial frequency was 4.00 c/deg and when temporal frequency was 7.55 Hz; however no significant differences between frequencies were found. The mixed findings provided some support for past findings, implying that cells are finely tuned to detect certain stimulus properties, and demonstrated NIRS as a valid …

The Effect Of Shifting Between Internal And External Foci Of Attention On Throwing Accuracy, Jeremy Lowen

The Plymouth Student Scientist

A vast quantity of research has identified the benefits of an external focus on the performance and learning of motor actions. This study aims to isolate the effects that shifting attention between internal and external foci can have on performance. A within subjects design tested the throwing accuracy of 40 undergraduate psychology students in both internal and external focus conditions. Participants threw a tennis ball towards a target with their non-dominant hand over a period of 3 x 2 (counterbalanced) sets of 15 throws. The main effect of focus condition was significant; external focus eliciting higher scores of accuracy. The …

An Examination Of The Present And Future Selves Of Adolescents: Investigating Possible Selves And Self-Esteem In Relation To Gender And Attachment, Charlene Mcclelland

The Plymouth Student Scientist

Gender differences in self-esteem and possible selves have long been documented, in particular girls have been reported to have lower self-esteem and generate more interpersonally oriented possible selves than boys during adolescence. To explore these findings the current study wanted to look at gender differences and relationship factors i.e. attachment, in regards to possible selves. The study investigated the possible selves generated by 52 adolescents aged 13-16 years, as well as measuring their self-esteem and attachment patterns. As predicted the results supported previous findings on gender differences, with the addition of finding attachment differences. In particular insecure participants had lower …

A Review In Overhydration Underlying Exercise-Associated Hyponatremia, Jahn Firth

The Plymouth Student Scientist

Exercise-associated hyponatremia (EAH) is hyponatremia occurring during or up to 24 hours after prolonged physical activity. There is clear evidence that the primary cause of EAH is overconsumption of fluids relative to fluid losses. The electrolyte imbalance, in particular sodium triggered by overhydration is the aetiologic basis behind the illness. If untreated, hyponatremia causes cerebral and pulmonary edema resulting in seizures, coma and on occasion, death. Current understanding of overhydration underlying EAH is discussed. Aetiology, pathology, diagnosis, the role of sodium and preventive measures are key focal points in this review. The body of research spans more than two decades …

The Effect Of An Invasive Species On Predation Rates Upon Intertidal Barnacles, Rachel Linaker

The Plymouth Student Scientist

Non-indigenous species invasions are considered a large threat to native biota however the effects of which have been relatively understudied with respect to intertidal systems. Current literature surrounds the movement of species, however relatively little attempt has been made to quantify the effect. Using the invasive oyster drill Ocenebra erinacea and the native dogwhelk Nucella lapillus, this study aimed to investigate the effect of an invasive species‟ on predation rates over a one-week period feeding on the intertidal barnacle Chthamalus montagui. This was conducted by testing for the effects of increased conspecific density (abundance increase) and biodiversity (species number/identity) against …

College Student Reactions To Health Warning Labels: Sociodemographic And Psychosocial Factors Related To Perceived Effectiveness Of Different Approaches, Carla J. Berg, James F. Thrasher, J. Lee Westmaas, Taneisha Buchanan, Erika A. Pinsker, Jasjit S. Ahluwalia

Faculty Publications

Objective. To examine factors associated with perceiving different types of pictorial cigarette health warning labels as most effective in motivating smokers to quit or preventing smoking initiation among college students.

Method. We administered an online survey to 24,055 students attending six Southeast colleges in Fall, 2010. We obtained complete data for the current analysis from 2600.

Results. Current smoking prevalence was 23.5%. The largest majority (78.6%) consistently rated gruesome images as most effective, 19.5% rated testimonial images as most effective, and only a small proportion rated either standard (1.6%) or human suffering images (0.3%) as most effective. Subsequent analyses focused …

The Effects Of Changing From A Traditional Mathematics Curriculum To An Integrated Mathematics Curriculum On Student Mathematics Learning In Georgia, Catherine Lynn Mallanda

Dissertations

In 2005, the state of Georgia adopted a new integrated mathematics curriculum, the Georgia Performance Standards (GPS), which included a task-based approach for instruction. The purpose of this study was to determine if the new Georgia Performance Standards for mathematics increased students’ mean mathematics Preliminary SAT/National Merit Scholarship Qualifying Test (PSAT/NMSQT) scores or induced changes in the distribution of students’ scores on the PSAT/NMSQT. In addition, it was determined whether the level of course the student took, the type of implementation of the GPS curriculum or the preparation for implementation affected the PSAT/NMSQT scores. The results of the study indicated …

Following The Principles: Case Studies In Operations Other Than War, 1945-1999, Kevin Joseph Dougherty

Dissertations

In the post-World War II-era, operations other than war (OOTW) were the types of conflict most commonly faced by the United States. This term for what had previously been called by such names as small wars and low intensity conflict was incorporated in the Army’s capstone manual, Field Manual (FM) 100-5, Operations, in 1993. Field Manual 100-5 also listed objective, unity of effort, legitimacy, perseverance, restraint, and security as the six principles of OOTW. An analysis of eight OOTWs that occurred between 1945 and 1999 indicates that the balanced application of these principles is a reliable predicator of the operation’s …

Determining Content Validity For The Transition Awareness And Possibilities Scale (Taps), Melynda Burck Ross

Dissertations

The Transition Awareness & Possibilities Scale (TAPS) was crafted after an extensive review of literature was conducted to find research that examined and described specific aspects of transition programming: inputs, including supports and skill instruction; processes, including parent and support provider perceptions of the transition experience; and outcomes, including quality of life and traditional, quantitatively-measured outcomes. Once developed, the TAPS will allow a teacher or transition coordinator to know what information a family is lacking about transition planning and adult service options for students with disabilities who need extensive or pervasive supports.

In this research, content validity was used as …

A Comparison Of Adult- And Peer-Mediated Intervention For Autism: A Case Study, Maura Jones Moyle

Speech Pathology and Audiology Faculty Research and Publications

This study examined the response of a young child with autism to two play-based intervention conditions: adult-mediated and peer-mediated. The client was five years old, demonstrated moderate-to-severe autism, and exhibited developmental functioning between the 14 to 34 month level. The peer-mediated condition, based on a modified Integrated Play Group approach, utilized a typically developing peer who was three years of age. The study utilized an ABAB alternating treatment design to compare the impact of the adult- and peer-mediated interventions. Results from the current study suggest that the adult-mediated intervention resulted in increased engagement and more sophisticated social-communicative behaviors than the …

Using International Human Rights Law To Combat Racial Discrimination In The U.S. Criminal Justice System., Terrence Rogers

The Scholar: St. Mary's Law Review on Race and Social Justice

Statistics tend to show Black people commit most of the crime in the United States. Those statistics fail to account for unequal treatment of minorities at each stage of the criminal justice system. This unequal treatment may take the form of buy-and-bust operations, racial profiling, street sweeps, and other police activities which target people in low-income communities populated mainly by minorities. The American criminal justice system contains a cyclical, self-perpetuating aspect to the treatment of certain minorities. These perceptions direct a disproportionate amount of law enforcement attention on minorities, which leads to disproportionate arrests of minorities. The result shows racial …

Buffered Memory: A Hypothesis For The Maintenance Of Functional, Virus-Specific Cd8(+) T Cells During Cytomegalovirus Infection., Christopher M Snyder

Department of Microbiology and Immunology Faculty Papers

Chronic infections have been a major topic of investigation in recent years, but the mechanisms that dictate whether or not a pathogen is successfully controlled are incompletely understood. Cytomegalovirus (CMV) is a herpesvirus that establishes a persistent infection in the majority of people in the world. Like other herpesviruses, CMV is well controlled by an effective immune response and induces little, if any, pathology in healthy individuals. However, controlling CMV requires continuous immune surveillance, and thus, CMV is a significant cause of morbidity and death in immune-compromised individuals. T cells in particular play an important role in controlling CMV and …

Revisiting A Founding Assumption Of Genocide Studies, A Dirk Moses

Genocide Studies and Prevention: An International Journal

Genocide studies has come a long way over the past decade, having attained a level of intellectual sobriety, academic credibility, and public recognition virtually inconceivable forty years ago. At the same time, there have been signs of convergence between the fields of genocide studies and Holocaust historiography and studies. This development can be challenging for those in Holocaust studies and historio- graphy because the relationship betweem the two disciplines is complicated by genocide studies’ claim to incorporate the Holocaust into its object of inquiry, whereas the reverse does not hold. There is a potentially subordinate situation here, or at least …
