Gastrointestinal Health As A Stimulus For Native American Attraction To Medicinal Asteraceae And Further Implications For Human Evolution, Christopher David Stiegler
Graduate Theses and Dissertations
The Asteraceae, or the daisy family, is the largest family of flowering plants in the world, and its ethnobotanical, medical, and economic value is readily apparent cross-culturally. The aim of this thesis is to examine why constituent genera of the Aster family have remained such an integral part of human medicinal plant knowledge, and thereby to reveal any potential physiological, biological, or evolutionary mechanisms underlining human patterns of use regarding the Asteraceae. The present study focuses specifically on Native American plant knowledge made available by the expansive database in the works Daniel Moerman (Moerman 2003). Frequencies of plant use and …
The Effect Of Confirmation Bias In Criminal Investigative Decision Making, Wayne A. Wallace
The Effect Of Confirmation Bias In Criminal Investigative Decision Making, Wayne A. Wallace
Harold L. Hodgkinson Award for Outstanding Dissertation
Confirmation bias occurs when a person believes in or searches for evidence to support his or her favored theory while ignoring or excusing disconfirmatory evidence and is disinclined to change his or her belief once he or she arrives at a conclusion. The purpose of this quantitative study was to examine whether emotionally charged evidence and evidence presentation order could influence an investigator's belief in a suspect's guilt. The study included 166 sworn police officers (basic training recruits, patrol officers, and criminal investigators) who completed online surveys in response to criminal vignettes across different scenarios to record their measure of …

Universal health coverage (UHC) has gained prominence as a global health priority. The UHC movement aims to increase access to quality, needed health services while reducing financial hardship from health spending, particularly in low- and middle- income countries.
As a policy agenda, UHC has been identified primarily with prepayment and risk-pool- ing programs. While financing policies provide important benefits, increasing access to health services will require broader reforms.
For lessons, the UHC movement should look to the global HIV response, which has confronted many of the same barriers to access in weak health systems. Considerable success on HIV has resulted …
Manufacturer Perspectives On Content Transparency And Material Health In The Us Building Products Industry, Alexandra A. Muller
Manufacturer Perspectives On Content Transparency And Material Health In The Us Building Products Industry, Alexandra A. Muller
Open Access Theses
Flawed U.S. federal regulation of chemicals has resulted in a materials market that undervalues human and environmental health in favor of the more traditional attributes of price, performance and aesthetics. In the building products industry, global, dynamic supply chains and proprietary information concerns further complicate the task of assessing the material health of products.
Voluntary material health programs in the green building industry are intended to incentivize the manufacture and selection of safer products by getting companies to gather and assess ingredient, hazard and risk information from their supply chain. Building product manufacturers considered early adopters of the main material …
South Asian Women's Sexual Relationship Power: Examining The Role Of Sexism, Cultural Values Conflict, Discrimination, And Social Support, Chandni D. Shah
South Asian Women's Sexual Relationship Power: Examining The Role Of Sexism, Cultural Values Conflict, Discrimination, And Social Support, Chandni D. Shah
Open Access Dissertations
The lack of literature examining sexual experiences of South Asian women in dating relationships has important implications for the healthy development of long lasting romantic relationships. It is important to understand South Asian women’s relationship experiences in the context of power and sexism (interpersonal power framework; Pulerwitz, Gortmaker, & DeJong, 2000) and the role of specific sociopolitical factors (e.g., discrimination). Understanding South Asian women’s experiences of power in a sociopolitical context will help professionals when working with them to develop healthier sexual relationships through therapy outreach, and community programming. I used a correlational, quantitative study to examine the associations between …
Risks And Health Consequences Of Forgoing, Delaying, Or Having Trouble Accessing Needed Health Care Among Medicare Beneficiaries, Angelitta M. Spells
Risks And Health Consequences Of Forgoing, Delaying, Or Having Trouble Accessing Needed Health Care Among Medicare Beneficiaries, Angelitta M. Spells
Open Access Dissertations
Medicare provides health care coverage for approximately 93% of non-institutionalized older adults. Compared to uninsured adults, Medicare beneficiaries have greater access to needed healthcare including preventative care. However, disparities in accessing needed health care still exist among Medicare beneficiaries. Prior research has described barriers to accessing needed health care among older Medicare beneficiaries, such as transportation and health system characteristics, but little is known about prevalence, risks, or health consequences of older Medicare beneficiaries delaying, forgoing, or having trouble accessing needed health care. The three studies included in this dissertation followed a nationally representative sample of older Medicare beneficiaries to …
Evaluating The Prevalence And Effectiveness Of Breed-Specific Legislation, Felicia E. Trembath
Evaluating The Prevalence And Effectiveness Of Breed-Specific Legislation, Felicia E. Trembath
Open Access Dissertations
Dog bites pose a persistent public health problem, which some jurisdictions pass breed-specific legislation (BSL) to address. However, very little non-anecdotal evidence regarding the efficacy of BSL has been presented. Currently, BSL research is hampered by the absence of standard terminology, an established prevalence, or a scientific consensus on its effectiveness. The purpose of this study is to propose standardized terminology for BSL, establish the prevalence of each type of BSL in the USA, and conduct a systematic review of the effectiveness of BSL.
After review of terminology currently in use, as well as review of the regulatory actions of …
Impact Of Peer Relationship And Exposure To Violence On Posttraumatic Stress For Children At Risk For Maltreatment, Aura Ankita Mishra
Impact Of Peer Relationship And Exposure To Violence On Posttraumatic Stress For Children At Risk For Maltreatment, Aura Ankita Mishra
Open Access Theses
Post-traumatic Stress (PTS) symptomology includes ruminating thoughts and feelings around trauma, inability to feel and express emotions, and avoidance of things related to the traumatic event (American Psychiatric Association, 2000). Children and youth exposed to child maltreatment (abuse and neglect) are at higher risk of experiencing PTS. Extra-familial support, including peer support can reduce post-traumatic stress among youth (Pina et al., 2008). In the present study, Witnessing, Victimization, and Both Witnessing and Victimization due to Exposure to In-Home Violence and Peer Relationship Quality are evaluated as to their relative impact on PTS for children at risk for child maltreatment. Peer …
Breast Is Best: A Case Study Of Bottom-Up Implementation, Britni Ayers
Breast Is Best: A Case Study Of Bottom-Up Implementation, Britni Ayers
Graduate Theses and Dissertations
The institutional narrative surrounding breastfeeding is that breast is best. Research on infant feeding practices in the United States are abundant, especially among WIC recipients. Although WIC is championed as being a breastfeeding promotional venue, WIC recipients demonstrate lower breastfeeding rates than non-WIC recipients of similar economic standing suggesting the need for further research into the policies and breastfeeding promotional tools being implemented within WIC. Concurrently, research demonstrates that breastfeeding duration rates among WIC recipients can be prolonged with women’s interaction with a Breastfeeding Peer Counselors (BFPC). However, there has been little exploration into the experiences of BFPC or the …

Evaluation Of Negative Energy And Mineral Balance In Periparturient Holstein-Friesian Cattle, Ameer Ahmed Abdelhameed
Evaluation Of Negative Energy And Mineral Balance In Periparturient Holstein-Friesian Cattle, Ameer Ahmed Abdelhameed
Open Access Dissertations
Most cows experience a state of negative energy and mineral balance during the periparturient period. This imbalance is a major problem in the dairy industry and it is more frequently seen in multiparous cattle due to their high milk production. A large amount of fat and protein is mobilized in order to address the energy deficit during the periparturient period. The ability to accurately monitor energetics and electrolytes status using accurate, rapid, and low cost point-of-care instruments will assist in optimizing animal health and productivity.
This dissertation contains three studies that evaluated point-of-care instruments for measuring blood and plasma glucose, …
Neural Activity Reveals Effects Of Aging On Inhibitory Processes During Word Retrieval, Ranjini Mohan
Neural Activity Reveals Effects Of Aging On Inhibitory Processes During Word Retrieval, Ranjini Mohan
Open Access Dissertations
Word retrieval difficulties are one of the most frustrating problems in older adults. Poorer access to phonological (speech sound) representation of the target word has been postulated as the underlying deficit, supported by findings of improvement in word retrieval after phonological priming. But the great variability in naming performance among older adults may reflect cognitive scaffolding or compensatory neurophysiological processes related to maintenance or decline of naming abilities. In order better understand aging effects in the underlying neurophysiological changes associated with phonological retrieval, the present study examined electrophysiological correlates of phonological priming and word retrieval in adults across the lifespan. …

Dartmouth Scholarship
Background: Population attributable risk percent (PAR%) is an epidemiological tool that provides an estimate of the percent reduction in total disease burden if that disease could be entirely eliminated among a subpopulation. As such, PAR% is used to efficiently target prevention interventions. Due to significant limitations in current Clostridium difficile Infection (CDI) prevention practices and the development of new approaches to prevent CDI, such as vaccina- tion, we determined the PAR% for CDI in various subpopulations in the Medicare 5% random sample. Methods: This was a retrospective cohort study using the 2009 Medicare 5% random sample. Comorbidities, infections, and healthcare …
