When Arab Girls Break The Rules: A Qualitative Study, Camelia Ibrahim-Nassar Jan 2016

When Arab Girls Break The Rules: A Qualitative Study, Camelia Ibrahim-Nassar

Papers from the International Association for Cross-Cultural Psychology Conferences

Much has been written about the social control of Arab girls as one of the parental practices in a collective culture. Most girls are subject to strict rules and modesty codes and only a few dare to confront their culture by breaking the rules and engaging in risky unacceptable behavior. In this study, we interviewed eight such girls to examine why, when, and how they defied acceptable social norms and the consequences they suffered. Interestingly, the experience of risk taking yielded narratives that revealed a search for personal, social, and gender identity and highlighted the effect of the strictness of …

Why Do Cultural Differences So Often Trump Cross-Cultural Invariance?, Ype H. Poortinga Jan 2016

Why Do Cultural Differences So Often Trump Cross-Cultural Invariance?, Ype H. Poortinga

Papers from the International Association for Cross-Cultural Psychology Conferences

In this roundtable discussion I will advocate balancing psychological invariance and cultural variation. There are large and evident differences between the behavior repertoires of human groups. Cross-cultural researchers have endeavored to explain such differences in terms of broad and inclusive sociocultural dimensions, styles and traits. Among other contributions to this roundtable, I will argue that psychological patterning of cross-cultural differences is much less coherent than our literature tends to suggest. Admittedly, this is a serious challenge; if correct, it implies that cross-cultural psychology tends to engage in cultural stereotyping.

Culture + Behaviour + Comparison = Cross-Cultural Psychology, John W. Berry Jan 2016

Culture + Behaviour + Comparison = Cross-Cultural Psychology, John W. Berry

Papers from the International Association for Cross-Cultural Psychology Conferences

For many years I have advocated the view that cross-cultural psychology should have the following characteristics: it begins with an ethnographic search to select those settings that may provide the cultural and ecological contexts that are theoretically-relevant to the development of the particular behaviour of interest; this is followed by advancing hypotheses that link the context to the behaviour; then fieldwork is undertaken to further examine these cultural attributes, and to carry out the assessment of the behaviour of individuals. These activities are carried out across contexts for three reasons: (i) in order to gain sufficient variation in the cultural …

Evaluation Of Tillage, Crop Rotation, And Cover Crop Impacts On Corn Nitrogen Requirements In Southeastern South Dakota, Sara Louise Berg Jan 2016

Evaluation Of Tillage, Crop Rotation, And Cover Crop Impacts On Corn Nitrogen Requirements In Southeastern South Dakota, Sara Louise Berg

Electronic Theses and Dissertations

Nitrogen (N) is a vital factor of corn (Zea mays) production. Previous work in South Dakota has shown that there is uncertainty as to whether nitrogen requirements are the same for corn raised under no-till (NT) versus conventional till (CT) production systems. The objective of this study was to evaluate whether N requirements continue to be greater under long-term NT versus CT production systems in southeastern South Dakota, while also considering effects from cover crops and crop rotation. This was a two year study conducted at the SDSU Southeast Research Farm near Beresford, SD; it was superimposed on a long-term …

Starchy Surveillance, Ashley Meyer, Deborah Herrington, Stephen Rybczynski Jan 2016

Starchy Surveillance, Ashley Meyer, Deborah Herrington, Stephen Rybczynski

Peer Reviewed Articles

Students start learning about photosynthesis in early grade school, yet it is a topic they still struggle with in college. Misconceptions and lack of a deep understanding of photosynthesis may result from a paucity of quality science labs that address photosynthesis using inquiry. A quick internet search reveals that although a number of photosynthesis lessons are widely available, very few engage students in activities that allow them to actively construct an understanding of the principles of photosynthesis. Rather, most are cookbook style confirmation labs. The lesson presented here requires students to answer fundamental questions underlying photosynthesis using data they collected. …

Neoliberalism Redux: The Global Health Policy Agenda And The Politics Of Cooptation In Latin America And Beyond, Anne E Birn, Laura Nervi, Carlos Eduardo Siqueira Jan 2016

Neoliberalism Redux: The Global Health Policy Agenda And The Politics Of Cooptation In Latin America And Beyond, Anne E Birn, Laura Nervi, Carlos Eduardo Siqueira

Gastón Institute Publications

This article explores the neoliberal cooptation of social justice-oriented global health policies over the last three decades, from primary health care and ‘health for all’ to various contemporary so-called ‘health equity’ initiatives, such as Universal Health Coverage and ‘health convergence’. The authors illustrate and contextualize the different periods and approaches with examples from a range of Latin American countries, drawing on diverse political experiences and social struggles in the health arena. The analysis concludes with reflections about the region’s experiences of resisting and challenging the neoliberal health agenda, in spite of domestic and global environments that have constrained these efforts, …

Identifying Values: Comparing Four Methods Of Values Identification, Emmie Hebert Jan 2016

Identifying Values: Comparing Four Methods Of Values Identification, Emmie Hebert

Electronic Theses and Dissertations

Values have been described, from a behavioral perspective, as “freely chosen, verbally constructed consequences of ongoing, dynamic, evolving patterns of activity, which establish predominant reinforcers for that activity that are intrinsic in engagement in the valued behavioral pattern itself “ (Wilson & DuFrene, 2009). Emerging research supports the psychological benefits of interventions with a values component. However, there has been little experimental research that explores systematic methods of getting participants and psychotherapy clients to identify their values. This study evaluated four methods of identifying values by comparing within-subject ratings of participant-generated values stimuli. Participants were undergraduate students at the University …

Scrupulosity, Trauma And Disgust, Oh My! Assessing The Potential Relation Between Religiosity, Trauma Symptoms And Disgust, Brooklee Lightsey Tynes Jan 2016

Scrupulosity, Trauma And Disgust, Oh My! Assessing The Potential Relation Between Religiosity, Trauma Symptoms And Disgust, Brooklee Lightsey Tynes

Electronic Theses and Dissertations

Lifetime prevalence rates for Posttraumatic Stress Disorder (PTSD) are estimated to be 6% in the general population. In the United States alone, an estimated 5.2 million adults will experience PTSD within the year (National Comorbidity Survey, 2005). However, a much larger number of the population will experience some form of trauma over the course of their lifetime. Research has demonstrated that the development of PTSD may be attributed to some factors (e.g., temperamental vulnerabilities, social ecological factors), which may predispose individuals to the development of the disorder. The purpose of this study was to test the association of moral disgust …

Sookie's Place(S): New Roadways Into The South Of The Southern Vampire Mysteries, Sarah Holder Jan 2016

Sookie's Place(S): New Roadways Into The South Of The Southern Vampire Mysteries, Sarah Holder

Electronic Theses and Dissertations

Charlaine Harris’ bestselling paranormal romance series, the Southern Vampire Mysteries is only beginning to be understood as more than a cultural phenomenon, but rather as a highly politicized and critical work of fiction that shines through genre designations such as romance, mystery, and fantasy. Much of this praise can be attributed to the series’ heroine, Sookie Stackhouse, who gracefully traverses boundaries that divide what are arguably racial and ethnic groups ever at odds with one another as they share political and social space. Her adventures therefore pose significant questions concerning diversity, equality, and nationalism, but more obviously they ask what …

Competitive Effects Of Increased Plant Species Richness And Increased Endemic Versus Native Generalist Species Dominance On The Invasive Grass Microstegium Vimineum During Oak Woodland Restoration, Sean Anthony Moyer Jan 2016

Competitive Effects Of Increased Plant Species Richness And Increased Endemic Versus Native Generalist Species Dominance On The Invasive Grass Microstegium Vimineum During Oak Woodland Restoration, Sean Anthony Moyer

Electronic Theses and Dissertations

The hypothesis that species-rich assemblages are resistant to invasion by non-native species has generated considerable research and controversy. However, the relevance of such research to the conservation of biodiversity is questionable, given that local species richness often does not correlate with regional or global species richness, two metrics undoubtedly important to conservation. Furthermore, species of greater conservation interest (i.e. endemics) and widespread generalist species may compete differentially with non-native invasive species. To test whether plant species richness or species fidelity to a regionally rare habitat were more important in competitively suppressing an invasive species, I established a field competition experiment …

Community Ecology Of Soil Microbes In Southeast Usa Oak-Pine Woodlands, Ann L. Rasmussen Jan 2016

Community Ecology Of Soil Microbes In Southeast Usa Oak-Pine Woodlands, Ann L. Rasmussen

Electronic Theses and Dissertations

Soil microbial communities can have important effects on plant growth and plant community ecology; however, the relationships between trees and soil microbial communities are still relatively poorly understood. Here i examine several of these relationships. Chapter 1 examines how ecological restoration and environmental conditions affect the community composition and enzyme activities of Ectomycorrhizal fungi (emf). Chapter 2 considers whether host specificity in emf structures taxa occurrence on oaks and pines, and chapter 3 investigates how ash addition affects oak seedling growth and the soil bacterial community. I found that while wildfire lowered emf diversity, prescribed burning did not. Ectomycorrhizal root …

Characterization Of Charge Accommodation In Biologically Important Hydrogen-Bonded Clusters, John Thomas Kelly Jan 2016

Characterization Of Charge Accommodation In Biologically Important Hydrogen-Bonded Clusters, John Thomas Kelly

Electronic Theses and Dissertations

The underlying motivation of chemical physics and physical chemistry is to understand naturally occurring chemical and physical processes from the nanoscopic molecular level to the macroscopic condensed phase. Over the past half-century, experimentalists have developed a number of laser-based analytical techniques to bridge the gap between the bulk phase and the single molecule. Here, we look at bulk phase and gas phase clusters to compare the local hydrogen-bonded network. To better understand the role noncovalent interactions have on biologically relevant building blocks in a natural environment, we compare the microhydration of gas phase cluster ions to condensed phase spectra. The …

Genetic And Temporal Variation In Resource Exchange Between An Ectomycorrhizal Fungus, Rhizopogon Occidentalis, And Seedlings Of Pinus Radiata, Mariah Meachum Jan 2016

Genetic And Temporal Variation In Resource Exchange Between An Ectomycorrhizal Fungus, Rhizopogon Occidentalis, And Seedlings Of Pinus Radiata, Mariah Meachum

Electronic Theses and Dissertations

Various economic theories have been adapted to explain the evolutionary persistence of resource exchange mutualisms such as mycorrhizae. The ratio of resources exchanged is an important variable comto all these models. Measuring resource exchange ratios is the first step in testing the hypotheses predicted by these models and will provide insight into resource dynamics of mutualisms. We examined how the carbon, nitrogen and phosphorus resource exchange dynamics between Pinus radiata and an ectomycorrhizal fungus, Rhizopogon occidentalis, varied between native populations of Pinus radiata and over the first 64 weeks of the mycorrhizal mutualism. Using a mycocosm approach, the C:N and …

Loblolly Pine Genetics Structure Its Mycorrhizal Community, Bridget Joan Piculell Jan 2016

Loblolly Pine Genetics Structure Its Mycorrhizal Community, Bridget Joan Piculell

Electronic Theses and Dissertations

Plant populations are constantly exposed to a multitude of biotic and abiotic environmental selection pressures. The ability of a population to persist in or adapt to its environment is heavily influenced by the genetic underpinnings of the traits involved. Thus, in order to understand patterns in current plant populations, and to predict future populations dynamics, an understanding of the genetic basis of adaptive traits is necessary. For example, genetic correlations between traits (driven by pleiotropy or linkage disequilibrium) could influence how species evolve under multiple, conflicting selection pressures, potentially either constraining or enhancing the adaptation of species to each other. …

Raft Polymerization Of Ph-Responsive, Diblock Copolymers For Nucleic Acid Delivery Vehicles, Annie Katherine Mcclellan

Electronic Theses and Dissertations

Since the development of gene therapy, a variety of non-viral nucleic acid delivery vehicles have been prepared and studied for their transfection efficiencies. Recently, polymeric gene delivery vehicles have gained popularity for their low immunogenicity and high transfection efficiency. With the advent of controlled radical polymerization (CRP) and more specifically reversible addition-fragmentation chain transfer (RAFT) polymerization, it is now possible to develop well-defined polymers with predicted molecular weights and architectures. The work presented here focuses on the RAFT polymerization of a family of amphiphilic, cationic copolymers to be utilized for nucleic acid delivery. These copolymers are composed of a stabilizing …

Gas Exchange Of Hg Over Wetlands, Effect Of Biochar And Activated Carbon On Hg Emissions From Soil, And Seasonal Concentrations Of Hg In Rain, Divya Nallamothu

Electronic Theses and Dissertations

Mercury (Hg) is a global pollutant with human-health and ecological impacts. Gaseous Hg exchange between the atmosphere and aquatic or terrestrial surfaces serves as an important, but not well understood, route for Hg to enter and exit ecosystems. To better understand the role of gaseous Hg exchange in the biogeochemical cycling of Hg, we investigated Hg0 fluxes over natural wetlands (Sky Lake) and artificial wetlands (UM Field Station) using a dynamic flux chamber and an Hg vapor analyzer based on atomic fluorescence (Chapter 1). We also examined the effect of activated carbon and biochar on Hg emissions from soils for …

Multi-Scale Nanoindentation For Characterization Of Oil Shales, Zachary N. Miller Jan 2016

Multi-Scale Nanoindentation For Characterization Of Oil Shales, Zachary N. Miller

Electronic Theses and Dissertations

Studies of the effects of polishing techniques, scale of nanoindentation, and petrophysical properties were conducted on both Woodford and Tuscaloosa Marine Shale. Polishing procedures include both an in-house developed, mechanical sample preparation protocol as well as ion beam milling. The elastic modulus and hardness of each mechanically polished sample was found to have larger value than those that were ion-milled. Additionally, at low loads, the samples resulted in having high standard deviation. This high deviation was found to be significantly reduced by testing at higher loads. The variations in results between mechanically polished and ion beam milled samples is believed …

Validation Of Integrated Coast-Ocean Model Cche2d-Coast And Development Of Wind Model, Afshin Gazerzadeh Jan 2016

Validation Of Integrated Coast-Ocean Model Cche2d-Coast And Development Of Wind Model, Afshin Gazerzadeh

Electronic Theses and Dissertations

The eastern and southern coastlines of the United States are two of the most cyclone-prone areas of the world. The effects of tropical cyclones vary mainly depending on wind intensity and geological features of the coast that it is crossing. Higher winds potentially generate higher storm surges and consequently larger floods occur along the coastlines. Therefore, it is critical to accurately predict winds, storm surge, and waves associated with a hurricane. In the present study, an integrated coastal and ocean process model, CCHE2D-Coast, is validated by assessing the model’s capabilities in simulating coast-ocean circulations driven by the astronomical tides on …

The Effect Of Hyperparameters In The Activation Layers Of Deep Neural Networks, Clay Lafayette Mcleod Jan 2016

The Effect Of Hyperparameters In The Activation Layers Of Deep Neural Networks, Clay Lafayette Mcleod

Electronic Theses and Dissertations

Deep neural networks (DNNs), and artificial neural networks (ANNs) in general, have recently received a great amount of attention from both the media and the machine learning community at large. DNNs have been used to produce world-class results in a variety of domains, including image recognition, speech recognition, sequence modeling, and natural language processing. Many of most exciting recent deep neural network studies have made improvements by hardcoding less about the network and giving the neural network more control over its own parameters, allowing flexibility and control within the network. Although much research has been done to introduce trainable hyperparameters …

The Corruption Of Promise: The Insane Asylum In Mississippi, 1848-1910, Whitney E. Barringer Jan 2016

The Corruption Of Promise: The Insane Asylum In Mississippi, 1848-1910, Whitney E. Barringer

Electronic Theses and Dissertations

The ideology of insane asylum reform, which emphasized the Enlightenment language of human rights and the humane treatment of the mentally ill, reached American shores in the early-mid-nineteenth century. When asylum reform began to disseminate throughout the United States, forward-thinking Mississippians latched onto the idea of the reformed asylum as a humane way to treat mentally ill Mississippians and to bolster the humanitarian image of a Southern slave society to its Northern critics. When the Mississippi State Lunatic Asylum opened in 1855, its superintendents were optimistic about the power of the state to meet mental healthcare needs. While Mississippi slave …

Cavaliers And Crackers: Landless Whites In The Mind Of The Elite Antebellum South, Jeffrey Glossner Jan 2016

Cavaliers And Crackers: Landless Whites In The Mind Of The Elite Antebellum South, Jeffrey Glossner

Electronic Theses and Dissertations

Due to their marginalized role in southern society, landless white southerners have often been overlooked by historians who study social class, politics and intellectual culture in the antebellum south. But depictions of landless white southerners were prominent in contemporary elite literature and their place was debated extensively by social commentators. These depictions marginalized landless whites from southern honor culture and marked them as a people who were not quite white in a social and biological sense. This characterization was both a cause and effect of elite southern unease with the presence of a class of poor landless whites. This unease …
