Communal Infant Care In Black-And-White Ruffed Lemurs (Varecia Variegata)., Andrea Lee Baden

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Cooperative breeding describes a system where group members provide regular, unsolicited allomaternal care for offspring that are not genetically their own (Emlen 1991 Hrdy 2009). Most cooperative breeders live in groups with high reproductive skew (i.e. | singular breeders with helpers at the nest) however, skew falls along a continuum (Sherman et al. 1995 Vehrencamp, 2000), and, while rare, some cooperative breeders live in groups which experience low skew, subordinates commonly breed, and many if not all breeding individuals communally rear offspring (i.e. | plural or communal breeders) (Keller and Reeve 1994). Though phylogenetically widespread, communal breeding is rare. Among …

Breast Cancer Survivors' Perception Of Yoga Practice For Different Spans Of Time, Karyn Kirschbaum

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

This qualitative study uses an exploratory research design that incorporates both grounded theory and phenomenological approaches in order to gain insight into the meaning of yoga in relation to coping with breast cancer. The study focuses on the individual, lived experience and relies on in-depth interview strategies to capture the subjects' sensations and perceptions of the practice and utility of yoga over the duration of time. By interviewing women who practice yoga for different spans of time, several aspects are explored: if the length of time affects any observed changes; if transitional stages in yoga progression can be identified, and …

Constructive Developmental Theory: An Alternative Approach To Leadership, Anne Marie B. Hunter, Nancy M. Lewis, Paula K. Ritter-Gooder

Department of Nutrition and Health Sciences: Faculty Publications

As early as 1954, the critical value of leadership in dietetics was described by Rourke, who wrote, “When the day comes that your executive abilities equal your scientific knowledge, your profession (dietetics) will be secure. Until that day, you will be faced with a constant and unwelcome challenge” (1). Career and leadership skills development have been identified as an area for further attention by American Dietetic Association (ADA) practitioners and student members (2). Creation of the ADA Leadership Institute in 2003 represented an awareness of the need to invest in developing dietetic leaders (3). Proficient leaders are critical in keeping …

The Induction Of Positive Affect In A Community Setting Using Electronic Communications., Philip Andrew Smeltzer

Electronic Theses and Dissertations

Objective: To evaluate the influence of positive affect inductions on daily and weekly Positive and Negative Affect Scales (PANAS) in a community setting. Methods: Humor messages were distributed to participants four times per day during a treatment week with general health messages distributed in the crossover week. Subjects completed a series of self-report psychosocial and behavioral survey instruments on a weekly basis and daily PANAS responses. Messages were delivered through either email or SMS/text messages. Results: The daily and weekly PANAS scores were higher during treatment periods compared to the neutral periods. The observed trends were suggestive of successful positive …

Characterization Of The Ai-2-Dependent Quorum Sensing Pathway In Aggregatibacter Actinomycetemcomitans., Elizabeth A. Novak

Electronic Theses and Dissertations

Quorum sensing in the oral pathogen Aggregatibacter actinomycetemcomitans is dependent upon the soluble signaling molecule AI-2, but it is not known how the initial detection of AI-2 is coupled to the downstream regulation of gene expression that confers complex phenotypes such as biofilm formation and iron acquisition. Here we show that expression of a two-component system encoded by qseBC is induced by AI-2 in A. actinomycetemcomitans and that induction of qseBC requires the AI-2 receptors, LsrB and/or RbsB. Inactivation of the sensor kinase gene qseC resulted in a significant reduction of in vitro biofilm growth and in vivo virulence using …

Regulation Of Morphogenesis By Ammonium Transporters In Ustilgo Maydis., Jinny A. Paul

Electronic Theses and Dissertations

Many species of fungi undergo a dimorphic transition to switch from a unicellular yeast-like growth form to a filamentous growth form. Ustilago maydis undergoes such a transition, in response to successful mating events and subsequent host cues, to form a filamentous pathogenic form. U maydis also undergoes haploid filamentous growth in response to several environmental cues including, but not limited to nutrient limitation, pH, lipids, among others. Ammonium transporter proteins (Amts) play an essential role in controlling the dimorphic transition in response to nutrient limitation, specifically nitrogen in the form of ammonium. I demonstrate a role for the U maydis …

Food Stamps And Dependency: Disentangling The Short-Term And Long-Term Economic Effects Of Food Stamp Receipt And Low Income For Young Mothers, Thomas P. Vartanian, Linda Houser, Joseph Harkness

The Journal of Sociology & Social Welfare

The Food Stamp Program (FSP) remains one of the most widely used of all U.S. social "safety net" programs. While a substantial body of research has developed around the primary goals of the program- improving food access, nutrition, and health among lowincome families-less attention has been paid to the broader goals of hardship and poverty reduction. Using 38 years of data from the Panel Study of Income Dynamics, we examine several immediate and longer-term economic outcomes of early adult FSP participation for a sample of3,848 young mothers. While FSP participation is associated with some negative outcomes in the immediate future …

The Theory And Practice Of Genetically Engineered Crops And Agricultural Sustainability, David E. Ervin, Leland L. Glenna, Raymond Adelard Jussaume

Institute for Sustainable Solutions Publications and Presentations

The development of genetically engineered (GE) crops has focused predominantly on enhancing conventional pest control approaches. Scientific assessments show that these GE crops generally deliver significant economic and some environmental benefits over their conventional crop alternatives. However, emerging evidence indicates that current GE crops will not foster sustainable cropping systems unless the negative environmental and social feedback effects are properly addressed. Moreover, GE crop innovations that promote more sustainable agricultural systems will receive underinvestment by seed and chemical companies that must understandably focus on private returns for major crops. Opportunities to promote crops that convey multi-faceted benefits for the environment …

A Measure Of Self-Efficacy Among Agency Directors To Offer Nutrition Education To Lowcountry Food Bank Clients, Lucie Maguire

All Theses

In 2005, the Lowcountry Food Bank (LCFB) in Charleston, SC, launched an initiative to provide nutrition education to clients that seek food assistance. The agency directors of the 332 member agencies of the LCFB are in direct contact with clients, therefore they could provide nutrition education rather than the LCFB staff alone. As such, the self-efficacy of agency directors to deliver nutrition education must be measured. The objective of this project was to measure the self-efficacy of agency directors of the LCFB. A 17-item instrument measuring self-efficacy was developed, including ten validated items from the General Self-Efficacy Scale and an …

Biological Sciences Faculty Research

Human activity in the last century has led to a significant increase in nitrogen (N) emissions and atmospheric deposition. This N deposition has reached a level that has caused or is likely to cause alterations to the structure and function of many ecosystems across the United States. One approach for quantifying the deposition of pollution that would be harmful to ecosystems is the determination of critical loads. A critical load is defined as the input of a pollutant below which no detrimental ecological effects occur over the long-term according to present knowledge. The objectives of this project were to synthesize …

Behavioral And Environmental Correlates Of Parasite Burden In Eulemur Cinereiceps From Southeastern Madagascar, Sara Katharine Martin

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The grey-headed lemur, Eulemur cinereiceps, is among the top 25 most endangered primates. This work investigated behavioral and environmental correlates of parasite exposure through the evaluation of parasite burden in two wild metapopulations of E. cinereiceps in southeastern Madagascar. Understanding the relationship between primate behavior, environment and primate disease risk is critical for the conservation of primates and their ecosystems. The presence and distribution of parasites among primate populations is the result of primate exposure to parasites through both behavioral and environmental variables. Primate exposure to parasites is often the result of either host social behaviors or habitat use behaviors. …

Determination Of Sexual Dimorphism From The Proximal Femur In A Heterogeneous North American Population, Kathleen Elizabeth Droesch

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Many studies support the use of population specific standards to establish sexing of skeletal remains. Classic collections, which have been used to establish population standards, may not be reflective of modern societies, which are frequently composed of multiple ethnicities. In this study, vertical head diameter (VHD), superior-inferior neck diameter (SID), hip axis length (HAL) and neck-shaft angle (NSA) were measured from the proximal femur in order to determine if dimorphism can be established in a heterogeneous, contemporary population. Radiographic images from 159 males and 293 females were sampled. Comparisons using a two-tailed t-test indicated significant differences between males and females …

The Effects Of Dietary Immunostimulation On Atlantic Salmon (Salmo Salar) Immune Response To Sea Lice (Lepeophtheirus Salmonis) Infection, Sarah Ellen Friend

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The ectoparasitic copepod, Lepeophtheius salmonis, is considered to be the most economically damaging parasite in commercial Atlantic salmon (Salmo salar) culture, causing serious disease outbreaks which cost the industry nearly half a billion dollars annually. While other salmonid species show some resistance to this parasite, Atlantic salmon have previously shown very little in the way of inflammatory response to sea lice infection. The objective of this study was to enhance the immune response of Atlantic salmon to sea lice infection through the administration of in-feed immunostimulants. The efficacy of dietary additives to stimulate the immune response of Atlantic salmon against …

Observations Of Brachygnathia Superior (Underbite) In Wild Ruminates In Western Montana, Usa, J. A. Hoy, G. T. Haas, R. D. Hoy, Pamela Hallock

Marine Science Faculty Publications

Since spring of 1995 developmental malformations have been observed on many species of vertebrates. The most frequently observed of a range of skeletal anomalies is brachygnathia superior, also called mandibular prognathia, resulting from underdevelopment in length and width of the premaxillary bone forward of the upper premolars on ruminant species. To quantify these observations, facial anatomy was examined for bone and dental malformations on 1061 white-tailed deer (Odocoileus virginianus) that were accident-killed or died of natural causes between January 1996 and December 2010 in northern Ravalli County in the Bitterroot Valley of west-central, Montana, USA. Observations of brachygnathia …

Use Of Urban Bird Feeders By White-Winged Doves And Great-Tailed Grackles In Texas, Alayne B. Fronimos, John T. Baccus, Michael F. Small, Joseph A. Veech

Bulletin of the Texas Ornithological Society

As White-winged Doves (Zenaida asiatica) and Great-tailed Grackles (Quiscalus mexicanus) expanded their range northward, these species have shown an increased affinity for urban areas, perhaps because of a constant supply of anthropogenic food sources. We compared use of bird feeders by both of these species to established avian species in urban central Texas. We used 15 feeding stations in San Marcos and 15 in San Antonio. We digitally recorded interaction events for half-hour intervals in summer 2009 and winter 2010. We used recordings to calculate total time spent by each species at each feeding station, count the number of aggressive …

Use Of The Health Belief Model To Assess Hand Hygiene Knowledge, Perceptions, And Practices Of Saudi Students Studying In The U.S., Najla Khateeb

All Theses

Many factors influence hygiene but those that have the greatest impact vary widely across population groups. Our aim was to characterize hand hygiene practices of Saudi students studying in the U.S. by completing two objectives: (1) assess hand hygiene knowledge, perceptions, and practices of Saudi students studying in the U.S. and (2) determine the relationship among knowledge, perceptions, and practices.
A modified version of the Health Belief Model was the theoretical framework to characterize hand hygiene practices. A web-based instrument was posted to the ¬DSaudis Studying in USAÁÂ Facebook page. The instrument was prepared in English then translated into Arabic. …

Testing Hypotheses Of The Demographic Transition In San Borja, Bolivia, Kristin Snopkowski

Anthropology ETDs

Understanding the demographic transition, a trend in which fertility drops after a period of population growth, has been an important area of anthropological and demographic research. This dissertation seeks to understand fertility change by testing five models that have been presented in the literature. The predictions that are unique to each hypothesis are tested in San Borja, Bolivia, a community currently undergoing a fertility transition. Low modern fertility seems counter-intuitive given the increase of individual wealth, but there have not been sufficient tests to lead to an understanding of why this occurs. Informational hypotheses explain fertility transition as a change …

Functional Analysis Of Poliovirus Protein 2catpase In Viral Rna Replication And Encapsidation Using Alanine Scanning Mutagenesis, Chunling Wang

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Polypeptide 2CATPase is one of the most thoroughly studied but least understood proteins in the life cycle of poliovirus. Within the protein, multiple functional domains, important for uncoating, host cell membrane alterations, RNA replication and encapsidation have previously been identified. In this study, charged to alanine scanning mutagenesis was used to generate conditional-lethal mutations in hitherto uncharacterized domains of the 2CATPase polypeptide, particularly those possibly involved in morphogenesis. Adjacent or clustered charged amino acids (2-4), scattered along the 2CATPase coding sequence, were replaced with alanines. RNA transcripts of mutant poliovirus cDNA clones were transfected into HeLa cells. Subsequently, ten lethal, …

Potential Of Three Brassica Cover Crops For Biofumigation In The Field And The Relationship Between Soil Myrosinase And Biofumigation Efficacy, Zachariah Hansen

All Theses

A greenhouse study was set up in January 2011 to investigate the effect of soil myrosinase concentration and Bacillus spp. on the release efficiency of isothiocyanates (ITCs) from freeze-dried `Pacific Gold' mustard leaf tissue after incorporation into soil. Seventeen diverse soil samples collected from various regions of South Carolina were used in the study. A correlation analysis was conducted to determine if soil myrosinase was positively correlated with ITC concentrations after mustard incorporation. ITC concentrations were then analyzed with soilborne Bacillus spp. populations, bean emergence, disease incidence, and shoot weight to identify significant correlations. Finally, the effect of freeze-dried `Pacific …
