Key Indicators Of Language Impact On Identity Formation In Belarus, Tony Brown Jan 2013

Key Indicators Of Language Impact On Identity Formation In Belarus, Tony Brown

Russian Language Journal

In 1986, a group of 28 intellectuals from Belarus wrote the following brief letter to then-General Secretary Mikhail Gorbachev: “Language is the soul of a nation, the supreme manifestation of its cultural identity, the foundation of its true spiritual life. A nation lives and flourishes in history while its language lives. With the decline of the language, culture withers and atrophies, the nation ceases to exist as a historical organism” (Letters to Gorbachev, 1987).


Dynamic Microtubules And Endomembrane Cycling Contribute To Polarity Establishment And Early Development Of Ectocarpus Mitospores, Jeffrey Jack Green, Diego Cordero Cervantes, Nick T. Peters, Kyle O. Logan, Darryl L. Kropf Jan 2013

Dynamic Microtubules And Endomembrane Cycling Contribute To Polarity Establishment And Early Development Of Ectocarpus Mitospores, Jeffrey Jack Green, Diego Cordero Cervantes, Nick T. Peters, Kyle O. Logan, Darryl L. Kropf

Faculty Publications

Many zygotes and spores of brown algae are photosensitive and establish a developmental axis in accordance with directional light cues. Ectocarpus siliculosus is being advanced as a genetic and genomic model organism for investigating brown alga development, and this report investigates photopolarization of the growth axis of mitospores. When exposed to unidirectional light, mitospores photopolarized and established a growth axis such that germination was preferentially localized to the shaded hemisphere of the spore body. The roles of the microtubule cytoskeleton and endomembrane cycling in the photopolarization process were investigated using pharmacological agents. Disruption of microtubule dynamics progressively reduced the percentage …


Feminism, Breastfeeding, And Society, Jen Bracken-Hull Jan 2013

Feminism, Breastfeeding, And Society, Jen Bracken-Hull

AWE (A Woman’s Experience)

A dichotomy exists among feminists regarding the views and contributions of breastfeeding. Across several waves of feminism women have argued for and against breastfeeding. Until recently, breastfeeding (regarding the bearing and nurturing of children) was seen as a responsibility that prevented women from participating in public circles. This article delineates the general contributions made by women who breastfeed including biological, social, emotional, and personal factors. Changes and accommodations are required for women who choose to breastfeed to not be disadvantaged.


The Several Faces Of Late-Gothic Eve: Gender And Marriage In The Mystery Creation And Fall Plays, Thomas Flanigan Jan 2013

The Several Faces Of Late-Gothic Eve: Gender And Marriage In The Mystery Creation And Fall Plays, Thomas Flanigan

Quidditas

The critical drive to make fundamental, substantive distinctions between Catholic and Protestant dogma and culture has always been central to early modern English studies, but over the past fifty years a prominent contingent of literary and historical scholars has endeavored more specifically to identify and articulate significant differences between Catholic and Protestant perceptions of women and marriage. According to one familiar, now widely accepted theory advanced primarily by Miltonists, a relatively feminist and pro-marriage Protestant ethic emerged in response to the extreme, aggressively misogynistic attitudes attributed to late-medieval Catholic thought. This paper will seek to demonstrate, through a close comparative …


Toward A Theory Of Interdisciplinarity: An Example Of Conceptual Integration/Blending In Teaching And Learning In Russian And East European Language-Based Area Studies, Anna Pleshakova, Kathleen M. Quinlan Jan 2013

Toward A Theory Of Interdisciplinarity: An Example Of Conceptual Integration/Blending In Teaching And Learning In Russian And East European Language-Based Area Studies, Anna Pleshakova, Kathleen M. Quinlan

Russian Language Journal

Most of problems in everyday and professional life are interdisciplinary, though most of our academic scholarship is contained within disciplines. To understand and solve such interdisciplinary problems, we must cross disciplinary boundaries. Yet, “the need to identify a method or/and logic of interdisciplinarity has, however, proven to be much easier to proclaim than to meet.”


Planning Prompts As A Means Of Increasing Rates Of Immunization And Preventive Screening, Hengchen Dai, Katherine L. Milkman, John Beshears, James J. Choi, David Laibson, Brigitte C. Madrian Jan 2013

Planning Prompts As A Means Of Increasing Rates Of Immunization And Preventive Screening, Hengchen Dai, Katherine L. Milkman, John Beshears, James J. Choi, David Laibson, Brigitte C. Madrian

Faculty Publications

Building on psychological insights about the way people make decisions, behavioral scientists have proposed various methods to increase behaviors that promote welfare without limiting freedom of choice (Thaler & Sunstein, 2008). Recently, researchers have begun exploring the power of such methods for encouraging people to engage in beneficial health-related behaviors, particularly those that are often put off or forgotten (Loewenstein, Brennan, & Volpp, 2007). For example, motivated by evidence of substantial inertia at the status quo, researchers have demonstrated that if people are automatically assigned an appointment to receive a flu shot (while retaining the right to change or cancel …


Prediction Of Sawdust Pyrolysis Yields From A Flat-Flame Burner Using The Cpd Model, Aaron D. Lewis, Thomas H. Fletcher Jan 2013

Prediction Of Sawdust Pyrolysis Yields From A Flat-Flame Burner Using The Cpd Model, Aaron D. Lewis, Thomas H. Fletcher

Faculty Publications

High heating rate pyrolysis experiments were performed on a softwood sawdust in a flat-flame burner reactor at temperatures from 1163 to 1433 K with particle residence times ranging from 23 to 102 ms at atmospheric pressure. Volatile yields of the 45−75 μm sawdust were measured and are believed to be similar to those that would occur in an industrial entrained-flow combustor or gasifier. A refractory tar yield near 1.5 wt % (dry, ash-free) was measured. A high percentage of the fully pyrolyzed sawdust char was spherical, having lost the original sawdust structure. It is suggested that the morphology of sawdust …


Respite Care, Marital Quality, And Stress In Parents Of Children With Autism Spectrum Disorders, Amber Harper, Tina Taylor, James Harper, Susanne Olsen Roper, Mikle South Jan 2013

Respite Care, Marital Quality, And Stress In Parents Of Children With Autism Spectrum Disorders, Amber Harper, Tina Taylor, James Harper, Susanne Olsen Roper, Mikle South

Faculty Publications

Parents of children with autism spectrum disorders (ASD) are at risk for having higher stress and lower marital quality than other parents. Survey data regarding respite care, marital quality, and daily hassles and uplifts were obtained from 101 mother-father dyads who were together raising at least one child with ASD (total # of children = 118). Number of hours of respite care was positively related to improved marital quality for both husbands and wives, such that a one-hour increase in weekly respite care was associated with a one-half standard deviation increase in marital quality. This relationship was significantly mediated by …

An Exploratory Investigation Of Marital Functioning And Order Of Spousal Onset In Couples Concordant For Psychopathology, Scott R. Braithwaite, Kimberly Van Orden, Mike Anestis, Katherine Merrill Timmons, Frank Fincham, Thomas E. Joiner Jr., Peter M. Lewinsohn

Faculty Publications

Individuals with a psychiatric disorder are significantly more likely to have a spouse with a clinical diagnosis—marital concordance. We used a community sample of 304 couples concordant for either Major Depressive Disorder (MDD) or Substance Use Disorders (SUDs) to examine the relationship between marital functioning and gendered patterns of mental health diagnosis onset. For SUD concordance, couples in which wives onset before husbands—in spite of typical later onset for males—reported lower levels of marital satisfaction compared to couples in which the husband onset first. For MDD concordance, couples in which husbands onset with depression before wives—in spite of typical later …

The Effects Of Practice On The Concurrent Performance Of A Speech And Postural Task In Persons With Parkinson Disease And Healthy Controls, Christopher Dromey, K Bo Foreman, Stuart Sondrup, Eon Jarvis, Shawn Nissen, Leland E. Dibble

Faculty Publications

Purpose. Persons with Parkinson disease (PD) demonstrate deficits in motor learning as well as bidirectional interference (the performance of one task concurrently interferes with the performance of another task) during dual-task performance. Few studies have examined the practice dosages necessary for behavioral change in rehabilitation relevant tasks. Therefore, to compare the effects of age and PD on motor learning during dual-task performance, this pilot study examined persons with PD as well as neurologically healthy participants during concurrent performance of postural and speaking tasks. Methods. Seven persons with PD and 7 healthy age-matched and 10 healthy young control subjects were tested …

Perceived Food And Labor Equity And School Attendance Among Ugandan Children Living In Kin Care, Jini Roby, Stacey Shaw, Laurel George Jan 2013

Perceived Food And Labor Equity And School Attendance Among Ugandan Children Living In Kin Care, Jini Roby, Stacey Shaw, Laurel George

Faculty Publications

Emerging research suggests that biological relatedness contributes to differential treatment between children being raised by kin and the biological children in the caregiver’s household. This potential concern may be elevated especially when household resources are stretched thin. In this study, 518 Ugandan youth and their caregivers were interviewed individually, examining the association between relatedness and perceived food and work equity, and school attendance. Household income, but not relatedness, was negatively associated with food inequity. However, relatedness was positively associated with perceived disparity in the distribution of work among children living in the household, and with children’s school attendance. These findings …


A Force Based Model Of Individual Cell Migration With Discrete Attachment Sites And Random Switching Terms, J. C. Dallon, Matthew Scott, William V. Smith Jan 2013

A Force Based Model Of Individual Cell Migration With Discrete Attachment Sites And Random Switching Terms, J. C. Dallon, Matthew Scott, William V. Smith

Faculty Publications

A force based model of cell migration is presented which gives new insight into the importance of the dynamics of cell binding to the substrate. The main features of the model are the focus on discrete attachment dynamics, the treatment of the cellular forces as springs, and an incorporation of the stochastic nature of the attachment sites. One goal of the model is to capture the effect of the random binding and unbinding of cell attachments on global cell motion. Simulations reveal one of the most important factor influencing cell speed is the duration of the attachment to the substrate. …


Remarital Chances, Choices, And Economic Consequences: Issues Of Social And Personal Welfare, Kevin Shafer, Todd M. Jensen Jan 2013

Remarital Chances, Choices, And Economic Consequences: Issues Of Social And Personal Welfare, Kevin Shafer, Todd M. Jensen

Faculty Publications

Many divorced women experience a significant decline financial, social, physical and psychological well-being following a divorce. Using data from the NLSY79 (n = 2,520) we compare welfare recipients, mothers, and impoverished women to less marginalized divorcees on remarriage chances. Furthermore, we look at the kinds of men these women marry by focusing on the employment and education of new spouses. Finally, we address how remarriage and spousal quality (as defined by education and employment) impact economic well-being after divorce. Our results show that remarriage has positive economic effects, but that is dependent upon spousal quality. However, such matches are …


No One Best Way: Work-Family Strategies, The Gendered Division Of Parenting, And The Contemporary Marriages Of Mothers And Fathers, W. Bradford Wilcox, Jeffrey P. Dew Jan 2013

No One Best Way: Work-Family Strategies, The Gendered Division Of Parenting, And The Contemporary Marriages Of Mothers And Fathers, W. Bradford Wilcox, Jeffrey P. Dew

Faculty Publications

The gender revolution of the last half-century has dramatically reshaped the nature, quality, and stability of marriage and parenthood in the United States. A half-century ago, most married mothers did not work outside the home, and most men and women preferred this arrangement. But over the course of the second half of the twentieth century, mothers streamed into the labor force, fathers devoted more time to childcare and housework, and public opinion largely swung behind these changes, with most Americans expressing normative support for working mothers, as well as for more egalitarian relationships between mothers and fathers in the home …


A Comparison Of Boltzmann And Gibbs Definitions Of Microcanonical Entropy For Small Systems, Randall B. Shirts Dec 2012

A Comparison Of Boltzmann And Gibbs Definitions Of Microcanonical Entropy For Small Systems, Randall B. Shirts

Faculty Publications

Two different definitions of entropy, S= klnW, in the microcanonical ensemble have been competing for over 100 years. The Boltzmann/Planck definition is that W is the number of states accessible to the system at its energy E (also called the surface entropy). The Gibbs/Hertz definition is that W is the number of states of the system up to the energy E (also called the volume entropy). These two definitions agree for large systems but differ by terms of order N-1 for small systems, where N is the number of particles in the system. For three analytical …


Nouns And Verbs In The Tagalog Mental Lexicon, Linda Walton Dec 2012

Nouns And Verbs In The Tagalog Mental Lexicon, Linda Walton

Theses and Dissertations

The purpose of this research was to study grammatical categories in the Tagalog mental lexicon using lexical decision tasks. Some linguists question whether words in Tagalog can be classified as nouns and verbs (Foley, 1998; Kaufman, 2011) because most root words can be inflected for any grammatical function and because verbs cannot be used in their uninflected form. Previous studies with English and German (Kauschke and Stenneken 2008) have shown that participants respond differently to nouns and verbs in lexical decision tasks. These studies have also shown that participants respond differently to transitive and intransitive verbs in lexical decision tasks. …


Using Hypertext And Case-Based Explanation To Help Learners Access Explanations To Unexpected Grammar Forms Encountered In Native Speech Examples, Kenneth B. Packer Dec 2012

Using Hypertext And Case-Based Explanation To Help Learners Access Explanations To Unexpected Grammar Forms Encountered In Native Speech Examples, Kenneth B. Packer

Theses and Dissertations

Three hypertext implementation strategies were evaluated against one another and against a control group to determine which best supported the language learner. Each version was also applied to four languages with diverse grammatical structures. These included Mandarin Chinese, Japanese, Portuguese, and Spanish. Language students were tested to determine how useful each strategy was in facilitating rapid and accurate explanation of grammatical structures embedded in native speech examples. Speed and accuracy were also measured as respondents applied a targeted grammar structure to construction of their own unique sentences. With respect to the four different languages, results were also analyzed to judge …


Does Attachment To Parents Mediate The Relationship Between Couple Conflict And Adolescent Self-Regulation?, Lisa Tensmeyer Hansen Dec 2012

Does Attachment To Parents Mediate The Relationship Between Couple Conflict And Adolescent Self-Regulation?, Lisa Tensmeyer Hansen

Theses and Dissertations

Adolescent self-regulation follows a developmental trajectory over time with ups and downs during maturation. This paper uses growth curve analysis to look at change in self-regulation over time. Although self-regulation scores may increase during latency, adolescents differ in levels of self-regulation due to biological and socialization factors. In addition, exposure to couple conflict has been shown to affect levels of self-regulation. The current study examined the role of attachment to parents as a mediator between couple conflict and adolescent self-regulation outcomes, controlling for gender of child. Participants were 681 families with a child between the ages of 11 and 13 …

Transcriptome And Methylation Analysis Of Gossypium Petal Tissue, Aditi Rambani Dec 2012

Transcriptome And Methylation Analysis Of Gossypium Petal Tissue, Aditi Rambani

Theses and Dissertations

Polyploidization instantly doubles all genome content by combining two genomes that have markedly different methylation and gene expression levels. This process may be accompanied by genetic and epigenetic changes in each genome. Sequencing of the transcriptome (RNA-seq) and the methylome (bisulfite treated libraries whole genome libraries) were used to measure gene expression and methylation levels of genic regions of allopolyploid cotton petals and petals of their diploid relatives. Many differentially expressed genes detected by RNA-seq were consistent with expression levels previously detected by microarrays. RNA-seq results also reconfirmed the presence of general polyploid gene expression trends like expression level dominance …


Transcriptome Analysis Of Drought Induced Stress In Chenopodium Quinoa, Joshua Arthur Raney Dec 2012

Transcriptome Analysis Of Drought Induced Stress In Chenopodium Quinoa, Joshua Arthur Raney

Theses and Dissertations

RNA-seq transcriptome analysis of Chenopodium quinoa at different water treatment levels was conducted in a greenhouse study using four water treatments (field capacity to drought) on a valley ecotype quinoa (variety Ingapirca) and an Altiplano Salares ecotype quinoa (variety Ollague). Physiological results support the earlier findings that the Salares ecotypes display greater tolerance to drought-like stress conditions than the valley ecotypes (as determined by growth rate, photosynthetic rate, stomatal conductance, and stem water potential). cDNA libraries from root tissue sample for each treatment x variety combination were sequenced using Illumina Hi-Seq technology in an RNA-seq experiment. De novo assembly of …

Long-Term Depression Of Excitatory Inputs To Gabaergic Neurons In The Ventral Tegmental Area, Philip J. Sandoval Dec 2012

Long-Term Depression Of Excitatory Inputs To Gabaergic Neurons In The Ventral Tegmental Area, Philip J. Sandoval

Theses and Dissertations

Dopamine cells within the ventral tegmental area of the brain are involved in motivation and reward. Drugs of abuse target these dopamine cells altering their activity and plasticity resulting in addiction. While dopamine cell activity is primarily involved in addiction, the GABA neurons in the VTA have also been shown to have an indirect role. By decreasing the activity of the inhibitory GABA inputs onto dopamine neurons abusive drugs can indirectly increase dopamine cell activity resulting in addictive behaviors. However, although GABA neurons are important in the perception of reward, much less is known about how the excitatory inputs to …


Mtor Pathway Activation Following Sciatic Stimulation In Wild-Type And Desmin Knockout Mice, Daniel S. Nelson Dec 2012

Mtor Pathway Activation Following Sciatic Stimulation In Wild-Type And Desmin Knockout Mice, Daniel S. Nelson

Theses and Dissertations

The 52 kDa intermediate filament protein desmin plays an important role in force transmission in skeletal muscle by connecting myofibrils at Z-lines and to the sarcolemma. Desmin content in muscle adapts to contractile activity and may be involved in cellular signaling mechanisms responsible for muscle growth. Purpose: To compare signaling responses of the mTOR pathway in wild type (WT) vs desmin knock out (KO) mice. Methods: WT (n=12) and KO (n=12) mice were exposed to high frequency electric stimulation of the left hindlimb to elicit an acute response of the mTOR pathway. Non-stimulated right hindlimbs were used as a within …


A Tree Theory Case Study In Steinernema, Camille Eileen Finlinson Porter Dec 2012

A Tree Theory Case Study In Steinernema, Camille Eileen Finlinson Porter

Theses and Dissertations

It is widely assumed that current phylogenetic methods are fairly accurate at recovering the evolutionary relationships among different species, but evaluating the relative success of this enterprise is a difficult task. This study addresses some fundamental questions associated with generating phylogenetic trees. The complete genomes of five species of Steinernema were sequenced and assembled. Genes were predicted in AUGUSTUS and orthologous genes were found from those data using OrthoMCL. I aligned 3890 genes in MAFFT and eliminated poorly aligned positions with GBlocks. I created individual trees for each gene as well as a supermatrix tree in PAUP*, using a closely …


Cultural Thinning Of Native Sagebrush Stands To Increase Seed Yields, Kurt David Elder Dec 2012

Cultural Thinning Of Native Sagebrush Stands To Increase Seed Yields, Kurt David Elder

Theses and Dissertations

Wyoming big sagebrush (Artemisia tridentata Nutt.) is an important native shrub in the Great Basin because of its wide distribution where it dominates over 60 million ha and provides essential habitat and forage for many varied species. The hand collection of sagebrush seed often results in seed scarcity and the available seed quantities are at times inadequate to revegetate large areas that have been disturbed, resulting in a demand for sagebrush seed. Study locations were selected near Scipio and Sahara sand dunes of Utah, and treatments were 1-) control, no treatment applied area left undisturbed 2-) general chemical strip …

Theses and Dissertations

This study examined the cost effectiveness of treating Anorexia Nervosa, Bulimia Nervosa, and Eating Disorder Not Otherwise Specified (NOS), as well as the effects that modality of therapy (i.e. individual, family, and mixed therapy), license of therapist, and secondary diagnosis had on recidivism and total cost of treatment in the care of these patients. One-thousand and thirty-eight patients (56 males, 982 females) diagnosed with Anorexia Nervosa, 1,674 patients (56 males, 1,618 females) diagnosed with Bulimia Nervosa, and 1,997 patients (197 males, 1,800 females) diagnosed with Eating Disorder NOS were included in this study. Results revealed that family therapy was the …


Characterization Of Sterile Tassel Silky Earl: A Homeotic B-Class Gene Involved In Specification Of Floral Organ Identity In Zea Mays, Steven Keith Williams Dec 2012

Characterization Of Sterile Tassel Silky Earl: A Homeotic B-Class Gene Involved In Specification Of Floral Organ Identity In Zea Mays, Steven Keith Williams

Theses and Dissertations

Specification of floral organ identity in angiosperm flowers is accomplished by the coordinated activity of A-, B-, C-, and E-class MADS-box genes. In the eudicots, B-class genes specify petal and stamen identity. This eudicot B-class function depends on the simultaneous expression of genes from two paralogous B-class lineages (the DEFICIENS/APETALA3 lineage and the GLOBOSA/PISTILLATA lineage). Proteins produced by genes from these two lineages interact as obligate heterodimers and together regulate the transcription of various downstream targets. These obligate heterodimers also positively regulate the transcription of the B-class genes themselves, thereby mediating a unique B-class autoregulatory feedback loop. There is compelling …
