Adult-Use Cannabis And State Research Agencies An Exploratory Study And Development Of A Harm-Reduction Course, Abigail Wiegand
Electronic Theses and Dissertations
The increasing demand of adult-use cannabis is outpacing the regulatory stride of the states that legalize recreational marijuana. This work is the product of two studies that focus on those states’ agencies that closely work with their constituents. They include those who are invested or reliant on cannabis businesses and those who consume cannabis for medical or recreational purposes. State agencies and resources are funded by those same constituents’ taxes, for which they have the responsibility to protect the public’s best interests as the industry grows. Chapter 2 describes an inquiry on what information and support is shared with adult-use …
Health-Related Quality Of Life (Hrqol) In Sexual Minority (Sm) College Undergraduate Students, Leigh Neptune
Health-Related Quality Of Life (Hrqol) In Sexual Minority (Sm) College Undergraduate Students, Leigh Neptune
Electronic Theses and Dissertations
It is well documented that disparities exist in health-related quality of life (HRQOL) among sexual minority (SM) youth and adults compared to their heterosexual peers, and among college undergraduate students compared to all young adults. Yet, no studies have been conducted to date examining HRQOL, diet quality, or weight dissatisfaction at the intersection of SM and college undergraduate student status. In 2020, a cross-sectional convenience sample of college undergraduate students (N=690) from the University of Maine and Rutgers University completed an online survey consisting of items assessing demographic variables, HRQOL, diet quality, and weight dissatisfaction. Of this sample, 23.9% (n=165) …

To Know The Land With Hands And Minds: Negotiating Agricultural Knowledge In Late-Nineteenth-Century New England And Westphalia, Justus Hillebrand
Electronic Theses and Dissertations
Ever since the eighteenth century, experts have tried to tell farmers how to farm. The agricultural enlightenment in Europe marked the beginning of a long arc of new experts aiming to change agricultural knowledge and practice. This dissertation analyzes the pivotal period in the late nineteenth and early twentieth century in Germany and the United States when scientists, improvers, and market agents began to develop comprehensive ways to communicate agricultural innovation to farmers. In a functional approach to analyzing the negotiation of agricultural knowledge through its communication in things, words, and practices, this dissertation argues that the process of change …
Enzyme-Assisted Fermentation And Chef Perspectives Of Green Crab Sauce, Holly Constance Leung
Enzyme-Assisted Fermentation And Chef Perspectives Of Green Crab Sauce, Holly Constance Leung
Electronic Theses and Dissertations
The European green crab (Carcinus maenas) is an invasive species which has caused considerable economic and ecological damage along U.S. coasts. Due to their small size, meat extraction from green crabs is laborious, and there is currently no well-established use for this abundant biomass. Developing a high-value, high-volume food product such as a fermented green crab sauce may stimulate the commercial harvesting of these crabs. Overall, the purpose of this research was to accelerate fermentation of green crab sauce using proteases and to gain insight into chef perspectives of fish sauce and a green crab sauce concept. The specific objectives …

Milk Phospholipids Extraction Using Switchable Solvents, Kaavya Rathnakumar
Electronic Theses and Dissertations
Phospholipids (PLs) found in milk are of great interest due to their health and nutritional benefits associated with their consumption. By-products generated during the manufacture of dairy products represent a source of PLs with potential for value-added opportunities. Currently, the extraction of PLs from by-products results in overall lowefficiencies, and it involves subsequent solvent separation and lipid recovery. This dissertation studied the extraction of milk PLs from by-product streams with a tertiary anime (N, N-dimethyl cyclohexylamine, CyNMe2) as a switchable hydrophilicity solvent. This type of solvents can be reversibly switched between a hydrophobic and hydrophilic form in the presence or …
