Assessment Of The Intake And Knowledge Of Folate/Folic Acid Among Unh Students, Jessica Lee Pelletier, Ruth Reilly, Sherman Bigornia

Honors Theses and Capstones

There are 3,000 U.S. pregnancies affected by spina bifida and anencephaly annually. If women consume adequate amounts of folic acid (400 mcg/day) one month before pregnancy and through the first trimester, then the risk of their infant developing a neural tube defect (NTD) is reduced by 50-70%. However, approximately 50% of pregnancies are unplanned, with some of the highest rates among 18-24 year olds. The purpose of this study was to evaluate the knowledge source, knowledge level, and intake of folic acid among college-aged students. Qualtrics surveys from 96 subjects (87.5% female, aged 18-24) were used for analysis. In the …


A Changing Gulf Of Maine: Investigating The Role Of Benthic Water Temperature In Determining The Timing Of Spiny Dogfish (Squalus Acanthias) Arrival And Departure In The Gulf Of Maine, Benjamin Donald Gallo Jan 2017

A Changing Gulf Of Maine: Investigating The Role Of Benthic Water Temperature In Determining The Timing Of Spiny Dogfish (Squalus Acanthias) Arrival And Departure In The Gulf Of Maine, Benjamin Donald Gallo

Honors Theses and Capstones

Spiny Dogfish (Squalus acanthias) is a highly migratory elasmobranch that undergoes annual migrations along the East Coast of the United States. Spiny dogfish have been studied extensively on the West Coast, but little information currently exists on the life history of this species in the Gulf of Maine (GOM). In the last few years, commercial gillnet fishermen in the GOM have been reporting unusual catch patterns while fishing offshore, perhaps indicating an increased abundance in dogfish and an extension of the length of time that dogfish occupy the GOM in a given year. Concurrent with these changes, rising …


Effects Of Silvopasture Establishment On Aqueous And Gaseous Soil N Losses At The University Of New Hampshire Organic Dairy Research Farm, Kathryn Ann Slebodnik Jan 2017

Effects Of Silvopasture Establishment On Aqueous And Gaseous Soil N Losses At The University Of New Hampshire Organic Dairy Research Farm, Kathryn Ann Slebodnik

Honors Theses and Capstones

The expansion of local agriculture in the New England region is putting increased pressure on farmers to expand their arable land base. While clear-cutting is a traditional method of converting forested land to agriculture, it is known for having adverse ecological impacts. To minimize these impacts, farmers can create a silvopasture which incorporates a portion of the original forest canopy into pastures or crop fields. This study evaluates the impact of land-use changes for agriculture on soil nitrogen (N) retention. In particular, this study investigates the differences in soil N turnover, gaseous loss, and aqueous loss among an established forest, …


The Relationship Of Life Stage To Daily Social Patterns Of Captive African Elephants (Loxodonta Africana) And The Correlation Of Handler Perceptions Of Elephant Personality To Demonstrated Social Behaviors, Alison Jeffrey Jan 2017

The Relationship Of Life Stage To Daily Social Patterns Of Captive African Elephants (Loxodonta Africana) And The Correlation Of Handler Perceptions Of Elephant Personality To Demonstrated Social Behaviors, Alison Jeffrey

Honors Theses and Capstones

Elephants typically have very strong social bonds, and social interactions can include affiliative, agonistic, or ambiguous behaviors. The social interactions and dominance hierarchy between individuals of a herd depend upon many factors, including maternal lineage, age, and sex. This study was designed to determine how social behaviors among a herd of captive African elephants varied throughout the day and to establish if the frequency of social interactions and age class were correlated. The study also aimed to determine if handler perceptions of elephant personality were an accurate predictor of the type and frequency of social behaviors observed, in addition to …


More Than Food: An Analysis Of Multidimensional Relationships In Our Food System, Jessica Erin Newnan Jan 2017

More Than Food: An Analysis Of Multidimensional Relationships In Our Food System, Jessica Erin Newnan

Honors Theses and Capstones

Food is an integral part of everyday life for human beings, thus meriting particular attention from research and education. Looking further in depth at the factors that influence food, it becomes apparent that this is a complex topic that is related to several systems within the constructs of society. Here, the food system is approached with the understanding that several systems influence food consumption options and decisions including the agricultural, economic, education, energy, health, and political systems. To identify the relationships more closely, a three-dimensional model was built to represent the food system and depict several key factors, their relationships, …


Daily Distance Moved And Home Range Analysis Of Female Cheetahs On Namibia's Commercial Farmland, Elisabeth Nicole Wise Jan 2017

Daily Distance Moved And Home Range Analysis Of Female Cheetahs On Namibia's Commercial Farmland, Elisabeth Nicole Wise

Honors Theses and Capstones

Fewer then 10,000 cheetahs remain in Sub-Saharan Africa. Namibia has the largest population, estimated to be 4,000. Habitat fragmentation and prey depletion from human expansion for agriculture has pushed 90% of cheetahs to reside on commercial farmland where there is an absence of larger predators. Radio telemetry was used to investigate the seasonal variation in home range size among nine female cheetahs on commercial farmlands on or near the Cheetah Conservation Fund in Otjiwarongo, Namibia. ArcGIS 10.3 and Geospatial Modeling Environment were used to calculate the overall and core home range size. This was estimated for the overall, annual, monthly, …


Characterizing Food Selectivity In Children With Autism, Samantha H. Wohlmacher Jan 2017

Characterizing Food Selectivity In Children With Autism, Samantha H. Wohlmacher

Honors Theses and Capstones

Food selectivity or “picky eating” affects a large percentage of children on the autism spectrum and as a result can have negative impacts on a child’s health and nutritional status (Cermak, Curtin, & Bandini, 2010). Few studies compare food selectivity in children on the autism spectrum to children with other developmental issues. Such a comparison may reveal how food selectivity presents itself uniquely in children on the autism spectrum. This study examined data from past health records collected from the Seacoast Childhood Development Center (SCDC). Thirty-eight children whose parents were concerned about their diets were taken from a larger sample …


Effects Of Equine Assisted Activities And Therapies On Equine Stress And Welfare, Sarah Jean Reega Jan 2017

Effects Of Equine Assisted Activities And Therapies On Equine Stress And Welfare, Sarah Jean Reega

Honors Theses and Capstones

Equine assisted activities and therapies (EAATs) are becoming an increasingly popular approach for therapy, therapeutic recreation, and learning for a broad range of human clients and participants. In the EAAT field, most research has been human-centric, focusing primarily on benefits of EAATs for participants and clients. Relatively little research has been conducted on the effects of EAATs on equine stress and welfare for equines engaged in EAAT sessions.

The effects of equine assisted activities and therapies on equine stress and welfare were studied by way of exploring current EAAT professionals’ experiences and views related to equine stress and welfare in …


The Influence Of Dietary Factors On Child Food Allergies, Jessica A. Shaw Jan 2017

The Influence Of Dietary Factors On Child Food Allergies, Jessica A. Shaw

Honors Theses and Capstones

Solid food introduction guidelines were recently amended to suggest that earlier introduction of peanuts is associated with a decreased prevalence of peanut allergies in high-risk children. This study aimed to determine whether there is a relationship between timing of introduction to the eight most common food allergens and the development of a food allergy. A total of 177 biological mothers of school-aged New Hampshire children completed the survey, but some were excluded due to answering <50% of the survey or not consenting to participate in the study. This left data on 101 participants, and the number of participants then varied between the various food allergens. Out of the 22 children with a milk allergy, 10 children were introduced to milk when they were less than 12 months old and 12 children were introduced at or after one year old. Fifty-nine percent of those introduced before 12 months of age developed a milk allergy, while only 17% of those introduced at or past 12 months developed a milk allergy (p = 0.00). Out of the 55 participants that developed a peanut/tree nut allergy, 12 were introduced to peanuts/tree nuts before the age of 12 months, and 43 introduced after. This means that 63% of those introduced before a year developed an allergy, while only 33% introduced later developed an allergy (p = 0.01). Although not significant, the results for egg, wheat, and peanut also demonstrated that earlier introduction may be associated with an increased risk of an allergy to that food. When only one child per family was considered, to exclude genetic confounders, the only significant value was for a milk allergy, in which 64% of children introduced before 12 months developed a food allergy, while only 18% of children introduced at or after 12 months developed one (p = 0.00). Results were similar even after the exclusion of child one and two. The results of this study concur with the recommendation of introducing milk after one year, but do not support earlier introduction to other food allergens in the general population.


Characterizing Food Insecurity At A Northeast Land-Grant University, Alana Ruth Davidson Jan 2017

Characterizing Food Insecurity At A Northeast Land-Grant University, Alana Ruth Davidson

Honors Theses and Capstones

In 2015, 15.8 million U.S. households were food insecure. While nationally food insecurity is assessed at the household and childhood level, university students are not explicitly monitored. The purpose of this study was to determine the prevalence of food insecurity at a northeast land grant university and characterize the contributing factors. A pilot study (n=211) was conducted in fall 2014 among a general nutrition class and found that 12.4% of students were food insecure, with another 5.7% reported marginal food security. A larger, university wide survey among graduate and undergraduate students was conducted in fall 2015 (n=943) and found that …
