Chicken Feather Protein Hydrolysate As A Biostimulant Improves The Growth Of Wheat Seedlings By Affecting Biochemical And Physiological Parameters, Ebru Genç, Ökkeş Atici

Turkish Journal of Botany

We derived a protein hydrolysate with rich content, which includes proteinogenic and nonproteinogenic amino acids, from chicken feathers by using an alkaline hydrolysis procedure with high yield success. After foliar application of aqueous solutions (0.05%, 0.075%, and 0.1%) of chicken feather protein hydrolysate (CFPH) to the seedlings of wheat (Triticum aestivum L. `Altındane? and `Bezostaya?), their effects were evaluated on important physiological and biochemical parameters. Treating plants with CFPH stimulated the expression of RuBisCo and increased root and shoot lengths, fresh and dry weights of the seedlings, and photosynthetic pigment content. In addition, applying CFPH at 0.075% and 0.1% concentrations …

Seed Germination Requirements Of Relictic And Broadly-Distributed Populations Of Chaerophyllum Aureum (Apiaceae): Connecting Ecophysiology And Genetic Identity, Alejandro Santiago, Oussama Ahrazem, Lourdes Gómez-Gómez, Miguel Ángel Copete, Raquel Herranz, Pablo Ferrandis

Turkish Journal of Botany

The main goal of this work was to relate the germinative ecology and genetic variability of Chaerolhyllum aureum L., an Apiaceae plant with dormant, underdeveloped embryos at the time of seed dispersal. We compared the seed germination physiology traits between a relictic geographically isolated Mediterranean population (Iberian System; central Spain) and a population located in the main, colder Atlantic Alpine core (Pyrenees; northern Spain). We analyzed both populations? genetic identity in parallel on the basis of ISSR?PCR analyses. Stratification, gibberellin treatment, and seed storage tests showed that C. aureum seeds have deep complex morphophysiological dormancy. The Iberian System population seeds …

The taxa identified belong to the genera Actinotaenium (1), Closterium (1), Cosmarium (15), Micrasterias (1), Spondylosium (1), Staurastrum (5), Teilingia (1), and Tetmemorus (1). Morphotaxonomy, ecology, and distribution of each species were discussed in detail.

Morphological And Leaf Anatomical Variability Of Crocus Cf. Heuffelianus Herb. (Iridaceae) Populations From The Different Habitats Of The Balkan Peninsula, Irena Raca, Milica Jovanovic, Irena Ljubisavljevic, Marina Juskovic, Vladimir Randelovic

Turkish Journal of Botany

Crocus cf. heuffelianus Herb. belongs to the series Verni Mathew and presents one of the most complex and critical taxa within the whole genus Crocus L. Depending on different authors, C. cf. heuffelianus is sometimes split into different taxa (e.g., C. scepusiensis (Rehmer & Wol.) Borbás ex Kulcz., C. vittatus Schloss. & Vuk., nom. illeg.). In order to disentangle the complicated taxonomical status of this species and to determine the degree of its morphoanatomical variability in the different environmental conditions, a comparative investigation of plant morphology and leaf anatomy of seven populations from the Balkan Peninsula was carried out. Morphometric …

Exploring The Relationship Between Anxiety Sensitivity And Heart Rate Variability, Bethany Gourley

Master's Theses and Doctoral Dissertations

Anxiety sensitivity (AS) is a multifaceted construct based on individual beliefs that anxiety symptoms and sensations will have harmful consequences. In general, literature demonstrates three underlying dimensions of AS: fear of cognitive dyscontrol (i.e., cognitive concerns), fear of physiological anxiety sensations (i.e., physical concerns), and fear of negative evaluation (i.e., social concerns). Elevated AS and underlying dimensions have been shown to underlie psychopathology, including anxiety and depression broadly, and are predictive of fear responding in the context of behavioral challenge paradigms whereby individuals with elevated AS demonstrate higher fear and sympathetic nervous system activation. To date, few studies have investigated …

Unravelling The D1r-D2r Heteromer, Margaret M. Champion

Master's Theses and Doctoral Dissertations

Dopamine receptors D1R and D2R form a heterooligomeric complex with signaling properties distinct from the individual receptors. Aberrant expression of this protein-protein complex is linked to the etiology of various neuropsychiatric diseases. Formation of the D1R-D2R heteromer is thought to be dependent upon electrostatic interactions occurring between the carboxyl tail of D1R and the third intracellular loop of D2R. Using this interaction site as template, I synthesized several peptides designed to disrupt the minimal area of the D1R-D2R interaction interface and tested these using whole cell lysates of human brain tissue and dopamine receptor constructs. I report that a synthetic …

The Influence Of Spirituality On Stressful Marriages In The Matanuska-Borough Of Alaska, Cheryl Vanessa Puryear

Walden Dissertations and Doctoral Studies

Because marriage brings two individuals who may or may not come from the same background into an intimate relationship, there are times when a marriage can be stressful. Although spirituality may be useful in coping with marital stress, there are few published studies on the influence of spirituality on stress in marriages in recent years. The purpose of this study was to examine the influence of spiritualty on stress in marriages. Differentation-based spirituality, an outgrowth of Kerr and Bowen's spirituality theory, served as the theoretical framework. A phenomenological research design was used to explore whether spirituality was a factor that …

The mental health of healthcare workers during the Ebola outbreak in West Africa was a serious concern for healthcare professionals and the mental health field. One area in West Africa where healthcare workers played a significant role during the Ebola outbreak of 2014 and 2015 was Sierra Leone. This qualitative research study was designed to explore the perceptions of Sierra Leoneans healthcare workers' mental health, how they coped, and treatment they received while providing care for Ebola virus patients. This study, with a phenomenological research approach, used purposeful sampling to recruit 10 healthcare workers to participate in semi structured, open-ended …

Demographic And Symptomology Differences Among Sexually Assaulted Children With Posttraumatic Stress Disorder, Kathleen Bethel-Pracht

Walden Dissertations and Doctoral Studies

Trauma due to sexual assault becomes a life changing event during a child's critical developmental years. Bronfenbrenner's ecological systems theory outlines the process of understanding an individual's environment and how disruptions in one level may affect other levels. This study determined if gender and ethnicity among sexually traumatized children diagnosed with post-traumatic stress disorder (PTSD) predict symptom severity as measured by the Trauma Symptom Checklist for Children (TSCC) after controlling for the socioeconomic level and home environment. The population consisted of 126 children aged 8 through 16 with at least a second-grade reading level. Multiple regression examined whether male and …

Nature Of Stressors On Female Law Enforcement Academy Recruits, Sandra Patricia Dillard

Walden Dissertations and Doctoral Studies

A problem in law enforcement academy training is that female recruits endure more stressors than male recruits endure. This can lead to fewer females opting for careers as law enforcement officers. The purpose of this study was to explore the unique stressors on female recruits when they are held to the same standards as males. The feminist theory was used as the theoretical framework for this study to depict how stress is perceived for the female. The first research question examined how outside stressors affected female trainees. The second research question examined how job-€related stressors affected female trainees. In-€depth, semistructured …

Parent Perceptions Of Biofeedback Treatment Effectiveness For Pediatric Migraine, Andrea Grando Weber

Walden Dissertations and Doctoral Studies

Gate control theory posits the idea that the brain and spinal cord have the ability to control the perception of pain sensation throughout the body. Biofeedback provides a proven way to teach a person how they may control their heart rate, breathing, and skin temperature. Through this process, individuals learn to lessen their migraine frequency and intensity. There are no studies to date that have measured the effectiveness of biofeedback in conjunction with medication for migraines in children despite established evidence of success in adults. In this study, an online format via SurveyMonkey was used to document the perceptions of …

Fish Encounters: Aquariums And Their Veterinarians In A Rapidly Changing World, Irus Braverman

Journal Articles

The extensive body of social science and humanities scholarship on zoos rarely discusses aquariums. Despite their independent historical trajectory and unique characteristics and challenges, aquariums are typically considered the younger sister to the more established terrestrial zoo institutions. This article is an initial exploration of modern public aquariums through the eyes of these institutions’ veterinarians, a small but rapidly growing, and quite influential, professional cohort. Drawing on in-depth interviews with a handful of aquarium veterinarians in various sites — including the United States, Canada, Israel, Portugal, Denmark, and Germany — the article documents some of the everyday challenges that these …

Modeling For Ecological Engineering, Lauren Simpson, Brooke A. Whitworth

Publications

In this classroom, high-school biology students learned how pine beetle outbreaks in North America have become some of the worst in a decade. To make sense of this phenomenon, students created iterative models with in-depth explanations over the course of the unit. These models were formative in developing students’ conceptual understanding of ecology and applying their knowledge to a real-world context. The models showed students the detrimental effects of the outbreaks and helped them wonder about efforts to manage them and preserve the forests. This allowed the teacher to connect their learning to an ecological engineering task. This task pushed …

Whiteness As Innocence, David Simson

Articles & Chapters

Current antidiscrimination law is exceedingly hostile to the project of race-conscious remediation—the conscious use of race to mitigate America’s persistent racial hierarchy. This Article argues that this broad hostility can be traced in significant part to what I call “Whiteness as Innocence” ideology. This ideology is a system of legal reasoning by which the formal principle of equality is filled with the substantive principle of white racial dominance via invocations of white innocence. That is, under this ideology, ideas about white innocence influence legal decisions on who is “alike” and “unalike” and what constitutes “alike” and “unalike” treatment in race-conscious …

Looking To The Future: Key Points For Sustainable Management Of Northern Great Plains Grasslands, Lora B. Perkins, Marissa Ahlering, Diane L. Larson

Natural Resource Management Faculty Publications

The grasslands of the northern Great Plains (NGP) region of North America are considered endangered ecosystems and priority conservation areas yet have great ecological and economic importance. Grasslands in the NGP are no longer self-regulating adaptive systems. The challenges to these grasslands are widespread and serious (e.g. climate change, invasive species, fragmentation, altered disturbance regimes, and anthropogenic chemical loads). Because the challenges facing the region are dynamic, complex, and persistent, a paradigm shift in how we approach restoration and management of the grasslands in the NGP is imperative. The goal of this article is to highlight four key points for …

Natural Resource Management Faculty Publications

Establishing baseline values for pathogen exposure and nutritional indices is necessary to monitor population health. However, little is known about white-tailed deer (Odocoileus virginianus) pathogen exposure and nutritional condition in the Northern Great Plains. Our objective was to assess pathogen exposure and establish nutritional indices for female white-tailed deer in Dunn and Grant counties, North Dakota and Perkins County, South Dakota. During 2014, we collected blood serum from 150 adult female white-tailed deer. Pathogens with the highest antibody prevalence included West Nile Virus (WNV; 85%), epizootic hemorrhagic disease (48%), and malignant catarrhal fever (32%). Serum values for creatine kinase, globulin, …

The Effects Of Forest Gaps On Animal Communication Networks, Cedar Arran Mathers-Winn

Graduate Student Theses, Dissertations, & Professional Papers

To avoid predation, many animals have evolved complex systems of anti-predator communication. Alarm calls are a key component of anti-predator behavior in many birds, and can provide detailed information about predators. Additionally, many birds and mammals produce and respond to each other’s alarm calls, creating a complex communication network. Furthermore, individuals may give alarm calls in response to the alarm calls of others nearby, without actually seeing a predator. This makes possible the spatial spread of alarm information, which can result in complex communication networks extending over a large area. However, this requires suitable habitat in which birds will be …

Pattern-Process Linkages In Forested Ecosystems, Eryn Elizabeth Schneider

Graduate Student Theses, Dissertations, & Professional Papers

Ecological pattern-process linkages have been called the Rosetta’s stone of ecology. The pattern-process linkage is a feedback whereby ecosystem processes drive structural patterns, and vegetation patterns also strongly influence vital ecosystem processes. The role of competition and gap dynamics in creating spatial heterogeneity was assessed in Sitka-spruce western hemlock forests. Results indicated that despite low species richness, these forests are structurally diverse with the spatial imprint of competition obscured by gap dynamics through stand development. The influence of forest structural and spatial heterogeneity on snow accumulation and persistence was examined in a mixed-conifer forest. Tree neighborhood type (open, clump, individual) …

Cognitive Impacts Of Age Based Stereotype Threat In Older Adults, Cali Caughie

Graduate Student Theses, Dissertations, & Professional Papers

The present study examined the effects of age-based stereotype threat (ABST) exposure on cognitive performance in older adults. Forty-nine community volunteers age 65 and older were stratified by age and gender and then randomly assigned to either an ABST group or a Control group. The ABST group read a paragraph describing the expected negative effects of age on cognition and the prevalence of Alzheimer’s disease in older adults. Participants in the Control group read a neutral paragraph of similar length and difficulty. It was hypothesized that individuals in the ABST group would perform worse on neuropsychological testing than individuals in …

Xflow: An Algorithm For Extracting Ion Chromatograms, Mathew M. Gutierrez, Rob Smith

Graduate Student Theses, Dissertations, & Professional Papers

Abstract: Mass spectrometry is a fundamental tool for modern proteomics. The increasing availability of mass spectrometry data paired with the increasing sensitivity and fidelity of the instruments necessitates new and more potent analytical methods. To that end, we have created and present XFlow, a feature detection algorithm for extracting ion chromatograms from MS1 LC-MS data. XFlow is a parameter-free procedurally agnostic feature detection algorithm that utilizes the latent properties of ion chromatograms to resolve them from the surrounding noise present in MS1 data. XFlow is designed to function on either profile or centroided data across different resolutions and instruments. This …

Association Of Health Facility Delivery And Risk Of Infant Mortality In Nigeria, Susan Adaku Ukwu

Walden Dissertations and Doctoral Studies

Infant mortality (IM) incidence in health facility systems during or after infant delivery is

substantially high in Nigeria. In this quantitative, cross-sectional study, the effects of skill

birth attendants (SBAs), prenatal care, and providers of prenatal care on IM in health

facility delivery centers were examined. The Mosley and Chen theoretical framework

informed this study and was used to explain the relationship between SBAs, prenatal

care, and providers of prenatal care and IM. One hundred and sixty infant deaths were

examined among mothers who used an SBA versus those who did not, mothers who had

prenatal care versus those without, …
