Effects Of Presenting Normative Alcohol Data On Perceptions Of College Drinking Behavior, Cullen Patrick Hardy

Antioch University Dissertations & Theses

Alcohol abuse, often in the form of binge drinking, is a problem that every college campus faces. Many researchers suggest that students believe that their peers drink more alcohol than is actually true, and use such a perception as a justification to drink more alcohol than should be consumed (Perkins, Haines, & Rice, 2005). The purpose of this study is to understand whether presenting normative information on drinking behavior among college students in two different ways (focus on heavy drinking or focus on abstinence) has an effect on the perceptions of drinking behavior.

Asperger's Syndrome/Autism Spectrum Disorder And Marital Satisfaction: A Quantitative Study, Kim L. Bolling

Few empirical studies exist that examine adult Asperger-affected relationships. The purpose of this study was to determine whether the marital satisfaction of individuals in relationships in which at least one partner has Asperger’s Syndrome (AS) or Autism Spectrum Disorder (ASD), differs in some significant way from the marital satisfaction of individuals in relationships in which neither partner has AS/ASD. Participants were 126 adults in relationships in which at least one partner had a diagnosis of AS or ASD, recruited from Asperger- and autism-related websites, social media, and organizations from English-speaking countries. Couples consisted of heterosexual and same-sex couples, couples with …

The Effects Of Baby Sign On Child Development, Joanna Scott

Open Access Theses & Dissertations

Introduction: Although the popular media supports the use of baby sign for enhanced developmental outcomes of children, empirical research verifying the actual effects of baby sign on the areas of communicative, cognitive, social, and physical development, is limited. Advocates of baby sign suggest pre-lingual symbolic communication may result in accelerated development whereas critics claim definitive conclusions cannot be drawn because of flawed methodology in the research. Purpose: The purpose of the present study was to explore whether baby sign has an impact on the developmental growth of children. Methods: Using a between groups research design, assessment data were obtained from …

Cleansing The Common: A Narrative-Intertextual Study Of Mark 7:1-23, Eike Arend Mueller

Dissertations

The conflict story of Mark 7:1–23 between Jesus and the religious leaders over the issue of defilement is the meeting point of a variety of disciplines: Purity studies, Jewish studies, exegetical studies, Historical Jesus studies, and studies on Jesus and the law. The crux of the passage, the meaning of the parable in v. 15 and the ensuing “cleansing” in v. 19, has been interpreted very differently. Scholars doing exegetical studies and studies on the relationship between Jesus and the law have maintained that the Gospel writer correctly reflects in 7:19 the meaning of Jesus’ parable (7:15), abrogating the clean/unclean …

An Analysis And Response To The Fear Of Evil Spiritual Forces Among Kamba Christians In The Light Of Biblical And Ellen G. White Teachings, Joseph Mutune Ndisya

Dissertations

This research aimed to discover whether there are any reasons from the Scriptures and writings of Ellen G. White regarding fear of evil spiritual forces. Thus research aims to understand the historical, cultural and religious reasons Kamba Christians frequently live in fear and dual allegiance. Biblical solutions will be suggested to permanently eliminate that fear. Fear is often so great that born-again Christians carry protective devices and practices which they believe will ward off the invading evil spiritual forces.

The Old Testament writings were examined to see how God wanted His people to relate to any evil power. The Old …

Use Of Passive Samplers To Detect Organochlorine Pesticides In Air And Water At Wetland Mountain Region Sites (S-Se Brazil), R. O. Meire, M. Khairy, A. C. Targino, P. M.A. Galvão, J. P.M. Torres, O. Malm, Rainer Lohmann

Graduate School of Oceanography Faculty Publications

Low-density polyethylene (LDPE) passive samplers were deployed in upland surface waters and the overlying atmosphere during May and June 2012, to determine the transport and trends of freely dissolved and gaseous organochlorine pesticides (OCPs) along altitudinal gradients in mountain regions in south and southeast Brazil. Gaseous OCP concentrations were dominated by hexachlorobenzene (3.0 to 29 pg.m^-3) and endosulfans (Ʃ= α-endosulfan + β-endosulfan + endosulfan sulphate, 170 to 260 pg.m^-3), whereas freely dissolved endosulfans were significantly higher than all other OCPs (p < 0.001). The presence of some target pesticides at the highest elevation sites indicated their efficient high-altitude transport from regional sources. Air-water exchange gradients indicated net deposition of most volatile and recently banned OCPs (e.g., HCB, endosulfan) over Brazilian mountains. Moreover, the exposure of these sites to large-scale continental airflows with varying source contributions may partly explain the atmospheric deposition of selected OCPs over upland freshwaters at tropical and subtropical mountains sites in Brazil. These findings, couple with LDPE passive air and water sampling measurements, point out the potential inputs from distant sources of semi-volatile chemicals to the two high-altitude sites.

Gaseous And Freely-Dissolved Pcbs In The Lower Great Lakes Based On Passive Sampling: Spatial Trends And Air-Water Exchange, Ying Liu, Siyao Wang, Carrie A. Mcdonough, Mohammed Khairy, Derek Muir, Paul Helm, Rainer Lohmann

Graduate School of Oceanography Faculty Publications

Polyethylene passive sampling was performed to quantify gaseous and freely dissolved polychlorinated biphenyls (PCBs) in the air and water of Lakes Erie and Ontario during 2011–2012. In view of differing physical characteristics and the impacts of historical contamination by PCBs within these lakes, spatial variation of PCB concentrations and air–water exchange across these lakes may be expected. Both lakes displayed statistically similar aqueous and atmospheric PCB concentrations. Total aqueous concentrations of 29 PCBs ranged from 1.5 pg L^–1 in the open lake of Lake Erie (site E02) in 2011 spring to 105 pg L^–1 in Niagara (site On05) …

Stigma and discrimination towards individuals living with Human Immunodeficiency Virus (HIV) is a serious issue. The stigma experienced by people with HIV relates to how the virus has been primary associated with so-called deviant behaviors (e.g. promiscuity and homosexuality). Stigma may isolate infected individuals from society and create barriers when accessing medical care and seeking social support. Conducted in El Paso, Texas, this study aims to better understand the issue of stigma through the life stories of individuals living with HIV and to test an exploratory model of a community-based intervention for fighting self-stigma. This research project is divided into …

A Rapid Approach For Considering Nonlinear Response Of Flexible Pavements Under Fwd And Estimation Of Remaining Lives Of Pavements, Shahabaldin Shirazi

Open Access Theses & Dissertations

Most mechanistic empirical pavement analyses are based on the layered elastic models where the stress sensitivity of geomaterials and their nonlinearity are either ignored or accounted for indirectly. Advanced numerical models, such as finite element models, are required to consider the nonlinear nature of the geomaterials. Existing pavements are often tested with the Falling Weight Deflectometer (FWD) to estimate the input moduli to the layered elastic models in order to estimate remaining life and structural capacity of pavements. It has been more than 30 years that FWD tests are being performed to measure structural adequacy of pavements. Backcalculation is the …

Graduate School of Oceanography Faculty Publications

The contributions of micro-, nano-, and picoplankton to particle export were estimated from measurements of size-fractionated particulate ²³⁴Th, organic carbon, and phytoplankton indicator pigments obtained during five cruises between 2010 and 2012 along Line P in the subarctic northeast Pacific Ocean. Sinking fluxes of particulate organic carbon (POC) and indicator pigments were calculated from ²³⁴Th–²³⁸U disequilibria and, during two cruises, measured by a sediment trap at Ocean Station Papa. POC fluxes at 100 m ranged from 0.65 to 7.95 mmol m⁻² d⁻¹, similar in magnitude to previous results at Line P. Microplankton pigments …

Detection And Quantification Of Oil Under Sea Ice: The View From Below, J. P. Wilkinson, T. Boyd, B. Hagen, T. Maksym, S. Pegau, Chris Roman, H. Singh, L. Zabilansky

Graduate School of Oceanography Faculty Publications

Traditional measures for detecting oil spills in the open-ocean are both difficult to apply and less effective in ice-covered seas. In view of the increasing levels of commercial activity in the Arctic, there is a growing gap between the potential need to respond to an oil spill in Arctic ice-covered waters and the capability to do so. In particular, there is no robust operational capability to remotely locate oil spilt under or encapsulated within sea ice. To date, most research approaches the problem from on or above the sea ice, and thus they suffer from the need to ‘see’ through …

Intensity Of Th And Pa Scavenging Partitioned By Particle Chemistry In The North Atlantic Ocean, Christopher T. Hayes, Robert F. Anderson, Martin Q. Fleischer, Sebastian M. Vivancos, Phoebe J. Lam, Daniel C. Ohnemus, Kuo-Fang Huang, Laura F. Robinson, Yanbin Lu, Hai Cheng, R. Lawrence Edwards, S. Bradley Moran

Graduate School of Oceanography Faculty Publications

The natural radionuclides ²³¹Pa and ²³⁰Th are incorporated into the marine sediment record by scavenging, or adsorption to various particle types, via chemical reactions that are not fully understood. Because these isotopes have potential value in tracing several oceanographic processes, we investigate the nature of scavenging using trans-Atlantic measurements of dissolved (< 0.45 μm) and particulate (0.8–51 μm) ²³¹Pa and ²³⁰Th, together with major particle composition. We find widespread impact of intense scavenging by authigenic Fe/Mn (hydr)oxides, in the form of hydrothermal particles emanating from the Mid-Atlantic ridge and particles resuspended from reducing conditions near the seafloor off the coast of West …

Examining Teachers' Acceptance And Use Of Mobile Applications And Ipads In Instruction Through The Technology Acceptance Model: A Mixed Methods Study, Danielle Nicole Navariz

Open Access Theses & Dissertations

With the addition of new technologies and the shift from digital learning to mobile learning, districts are rushing to purchase the latest mobile devices for their campuses. Despite this rush, as indicated by the growing number of pilot programs and 13 million iPads sold to education customers globally (Maestri, 2014), there is little research on the factors teachers consider when selecting mobile applications or the factors that impact their acceptance of the new technology. When implementing new technologies, teachers' acceptance of the technology must be examined to ensure proper use.

This Dissertation explored, through sequential mixed methods, teachersâ?? acceptance of …

Open Access Theses & Dissertations

Concussions affect an estimated 1.6 to 3.8 million individuals annually and can result in persistent symptoms and cognitive impairments in attention and memory. Concussions are a rising health concern especially in concussion management. Event Related Potentials (ERP) may more accurately assess cognitive recovery making better return to play decisions. In 2013, Sanchez found no significant difference between concussed athletes and non-concussed individuals in the in amplitude of the P300 ERP component using an auditory oddball task consisting of 2 different consonant, vowel (CV) syllables. Because participants were instructed to maintain a mental and verbal count of the target stimuli, a …

Combining Semiparametric Regression And Kriging For Prediction Of Pm2.5 Pollutant Levels At Unmonitored Locations With Meterological And Traffic Data, Justin Jonathan Strate

Open Access Theses & Dissertations

Particulate matter (PM) is defined by the Texas Commission on Environmental Quality (TCEQ) as "a mixture of solid particles and liquid droplets found in the air". These particles vary widely in size. Those particles that are less than 2.5 micrometers in aerodynamic diameter are known as Particulate Matter 2.5 or PM2.5. These particles are inhaled, and their health effects are still largely being studied. Past studies have assessed PM2.5 exposure of a population, yet individual exposure is more diffcult to assess and may vary widely in a population. Recent studies have combined semiparametric models with kriging (Li et. al [2012]) …

Dopamine Regulation Of Disengagement In The Basal Ganglia Circuitry, Mabel N. Terminel

Open Access Theses & Dissertations

Evidence suggests that dopamine (DA) is crucial for initiation and termination as well as sustained execution of movement. For the present study, it was hypothesized that DA plays a more important role in initiation and termination of movement than in its sustained production. To test these hypotheses, rats were trained to walk on a treadmill in a continuous and discontinuous (walk 30 secs/stop 15 seconds) fashion for one hour while striatal DA samples were collected using In Vivo Microdialysis (IVMCD). We predicted larger increases during discontinuous compared to continuous walking. It was found that brain dialysate levels of DA consistently …

Defeating Anisotropy In Material Extrusion 3d Printing Via Materials Development, Ángel Ramón Torrado Pérez

Today, the market of 3D printers covers all ranges of price, from very specialized, heavy and expensive machines, to desktop printers of only a few cubic inches in volume. Until recently, FDM technology had remained somewhat stagnant …

Accuracy And Precision Evaluation Of Traffic Speed Pavement Deflection Devices, Jorge Velarde

Open Access Theses & Dissertations

Pavement structural adequacy is considered an important aspect of the pavement management activities and can be incorporated by using surface pavement deflections. Continuous deflection technology, which has been around for several years, can potentially supplant single point deflection measurements provided by the Falling Weight Deflectometer (FWD). Previous studies have evaluated the traffic speed deflection devices (TSDD) accuracy and precision by comparing their results with FWD measurements. Although appropriate correlations and indices to compensate for the differences in load have been made, a direct comparison under the same loading conditions has not been reported in the literature.

The goal of this …

The following study is presented in two sections. In the first section variable-temperature magnetic and structural data of two pairs of diruthenium isomers (having an idealized D4h symmetry), one pair having axial ligands and the formula Ru2(DArF)4Cl (where DArF is the anion of a diarylformamidine isomer, and Ar = p-anisyl or m-anisyl) and the other one being essentially identical but devoid of axial ligands and having the formula [Ru2(DArF)4]BF4, show that the axial ligands have a significant effect on the electronic structure of the diruthenium core. Variable-temperature crystallographic and magnetic data as well as density functional theory (DFT) calculations unequivocally …

Optimization Schemes For The Inversion Of Bouguer Gravity Anomalies, Azucena Zamora

Open Access Theses & Dissertations

Data sets obtained from measurable physical properties of the Earth structure have helped advance the understanding of its tectonic and structural processes and constitute key elements for resource prospecting. 2-Dimensional (2-D) and 3-D models obtained from the inversion of geophysical data sets are widely used to represent the structural composition of the Earth based on physical properties such as density, seismic wave velocities, magnetic susceptibility, conductivity, and resistivity. The inversion of each one of these data sets provides structural models whose consistency depends on the data collection process, methodology, and overall assumptions made in their individual mathematical processes. Although sampling …
