All Peer-Reviewed Publications

The perception of key players in the fish farming sector towards the use of insects is important for their acceptance to adopt insects as an alternative protein source to the expensive fish meal. Perception was established through a cross-sectional study of 208 fish farmers and 71 fish feed traders and/or processors conducted in Gulu, Tororo and Masaka districts in Uganda, using descriptive, Chi-square, correlation and factor statistical analysis of the data collected. Males dominated the fish farming and fish feed trading and/or processing enterprises. Youths were involved to almost the same extent as adults. Fish farmers majorly practiced pond fish …

Uas Flight Operations In Complex Terrain: Assessing The Agricultural Impact From Hurricane Maria In The Central Mountainous Region Of Puerto Rico, Kevin Adkins

Publications

Hurricane Maria struck Puerto Rico in September 2017 as a Category 4 storm causing major damage to infrastructure, agriculture and natural ecosystems, as well as the loss of many lives. Among the crops hardest hit was coffee, one of the most important crops in Puerto Rico. As a perennial system, coffee takes various production forms along a gradient from high shade/biodiversity coffee farms to low shade coffee monocultures and therefore offers an ideal means for the study of resistance and resilience of an agroecosystem to weather and climate disturbance. During the summer of 2018, 14 impacted farms across the production …

Investigating Whether Implicit Prejudice Moderates The Impact Of Sexual Assault Survivors’ Minority Status On Negative Stereotyping, Tabitha Powell

UNF Graduate Theses and Dissertations

Although all sexual assault survivors have the potential to experience victim blame, Black women and transgender survivors of sexual assault face higher rates of victim blame and discrimination than their non-minority counterparts. This increased blame may be related to stereotypes about these individuals that do not align with “real” rape victim stereotypes. To understand how minority survivors of sexual assault are stereotyped, I investigated the intelligence and promiscuity ratings of minority survivors of sexual assault compared to their non-minority counterparts. Moreover, I investigated how implicit prejudice moderated the stereotyping of survivors. Participants read crime alerts that varied the race of …

We Can’T Afford To Turn A Blind Eye To Myopia, Christine Marie Bourke, James Loughman, Daniel Ian Flitcroft, Ekaterina Loskutova, Colm O’Brien

Articles

Background

Myopia is becoming increasingly prevalent throughout the world. It is an overlooked but leading cause of blindness, particularly among the working aged population. Myopia is often considered benign because it is easily corrected with glasses, contact lenses, or refractive surgery. Traditionally myopia has been classified into physiological and pathological subtypes based on the degree of myopia present. Higher levels of myopia are associated with increased risk of pathological complications but it is important to note that there is no safe level of myopia. Even low levels of myopia increase the risk of retinal detachment and other ocular comorbidities which …

Permitted Incentives For Workplace Wellness Plans Under The Ada And Gina: The Regulatory Gap, Elizabeth Pendo

Articles

Although workplace wellness plans have been around for decades, they have flourished under the Patient Protection and Affordable Care Act (“PPACA”) into a $6 billion-dollar industry. Under PPACA, a “wellness plan” is a program of health promotion or disease prevention offered by an employer that is designed to promote health or prevent disease and which meets the other applicable requirements of that subsection. Employers look to these programs to promote healthy lifestyles, improve the overall health of employees and beneficiaries, and reduce rising healthcare costs.

PPACA’s amendments to the Health Insurance Portability and Accountability Act (“HIPAA”) permit employers to offer …

Endolysosome Dysfunction And Inter-Organellar Signalling: An 'Iron-Ic' Story, Peter Halcrow

Theses and Dissertations

Endosomes and lysosomes (endolysosomes) are acidic organelles that are important both physiologically and pathologically. Implicated in the physiological and pathophysiological processes regulated by endolysosomes are readily releasable stores of cations including ferrous iron (Fe2+); an essential cofactor for the generation of reactive oxygen species (ROS). In determining the extent to which and mechanisms by which Fe2+ released from endolysosomes affects cellular functions it was important to determine levels of Fe2+ in endolysosomes. In some cells and by other researchers, FeRhoNox-1 was found to detect Fe2+ in acidic organelles known as Golgi. Here, using U87MG astrocytoma cells and primary cultures of …

An Exploration Of In-Person And Online Social Interaction: Examining The Effects Of Two Domains Of Social Behavior, Michael David Prazak

Theses and Dissertations

Social interaction is a core dimension of a fulfilling life. At present, the study of social interaction has focused largely on online social interaction due to the prevalence of this behavior in modern society, and the large impact of this manner of interaction on the psychological health of individuals. In terms of online behavior, both positive and negative effects may be experienced. Better understanding predictors and outcomes of online behavior would thus be a timely and valuable contribution to literature. The present study examined anxious and avoidant attachment style as predictors of social intimacy, levels of both in-person and online …

The Relationships Among Sleep Quality, Self-Efficacy And Performance In A Military Setting, Andrew D. Lautner

Relationships Between Sibling Physical Abuse And Lifetime Aggression Using Statistical Controls For Poly-Victimization, Ani Celine Mangold

Theses and Dissertations

Sibling abuse, as a potential contributor to lifetime aggression, is under-represented in the childhood maltreatment literature and minimized in American society. A contemporary survey study conducted using a large college sample (King et al., 2017) established significant relationships between sibling abuse (i.e., acts of physical abuse, threats of violence, and heated verbal conflict) and a range of lifetime aggression indicators after controlling for variance attributable to physical, sexual, intimate partner, and peer abuse. The present study examined sibling physical abuse and established these same relationships using a national sample after controlling for variance due to childhood physical abuse, observed violence …

Assessing The Robustness Of Time-To-Event Abundance Estimation, Kenneth E. Loonam

Graduate Student Theses, Dissertations, & Professional Papers

Abundance estimates can inform management policies and are used to address a variety of wildlife research questions, but reliable estimates of abundance can be difficult and expensive to obtain. For low-density, difficult to detect species, such as cougars (Puma concolor), the costs and intensive field effort required to estimate abundance can make working at broad spatial and temporal scales impractical. Remote cameras have proven effective in detecting these species, but the widely applied methods of estimating abundance from remote cameras rely on some portion of the population being marked or uniquely identifiable, limiting their utility to populations with naturally occurring …

Constructing Distance, Responsibility, And Memory Management Theories: An Anthropological Approach To Death Notification Interactions, Teresa Ann 'Lilly' White

Graduate Student Theses, Dissertations, & Professional Papers

Following a sudden or unexpected death, coroners often communicate the death to the next-of-kin. Death notifications may occur in hospitals, assisted living or dying facilities, homes, offices or workplaces, correctional facilities, schools, or other locations. A death notification has been perceived by outsiders and many researchers as a one-time, unilateral death-telling event. I argue, instead, death notifications are a series of social interactions and processes necessitating multiple actors and mechanisms. The death notification processes begin for the coroner when they are dispatched to a death scene, while the processes begin for the next-of-kin upon the death-telling event. The end is …

It examines the challenges and potentials of SfC’s efforts to implement food forests at 16 autonomous secondary schools. I contextualize this work within a larger conversation amongst food sovereignty activists and scholars around efforts to scale-out the use of agroecology through education. As the organization looks to …

Life Expectancy, Institute Of Portland Metropolitan Studies

Metroscape

Using Center for Disease Control data, we can visualize the spatial distribution of life expectancy estimates. For reference, the life expectancy of an average adult within the United States born in 2016 is 78.6 years. In the Portland Metropolitan region, 34 percent of the population lives in tracts with an average life expectancy below the United States average. These tracts are clustered largely in east Portland and Gresham. Future research should consider exploring other factors related to life expectancy such as race, income, and education.

Forms part of the continuing series Indicators of the Metroscape.

Examining Self-Regulation Of Learning Among Community College Students In Developmental Mathematics Courses, Katrina M. Eberhart

Theses and Dissertations

The ability to self-regulate one’s learning is crucial to the success of all college students, but is particularly important to those who are considered to be underprepared; it puts students on a path towards successful course completion, subsequent course enrollment, and eventual graduation from a postsecondary institution. Those enrolled in remedial coursework are a large portion of students labeled as underprepared. Remedial education is a contentious topic in higher education. Thus, it is critical to investigate the use of classroom strategies to foster a self-regulated environment to support student success in these early classes and move onto the classes needed …
