The Facilitators And Barriers For Active Seniors Attending Physiotherapy, Derek Wood

Theses and Dissertations (Comprehensive)

Physiotherapists are healthcare professionals who can be utilized by the senior population to maintain or improve their health (CPA, 2012). This research examined the experiences of physically active, injured seniors receiving treatment from a physiotherapist in order to understand the barriers and facilitators to treatment and recovery. The study also examined this population’s experiences with physiotherapy (PT) as well as their physical activity (PA) levels and the effect PA had on them.

The study employed a qualitative design which used background questionnaires and semi-structured interviews for data collection. Interviews were transcribed verbatim and thematic analysis was used to analyze the …

Exploring The Potential Neuromuscular Adaptations Associated With Sprint Interval Training, Samer Hassan

Theses and Dissertations (Comprehensive)

Purpose. The primary purpose of this study was to explore the acute (a single sprint interval training or SIT exercise session) and chronic (3 weeks of SIT) neural adaptations that may occur with the SIT (30 second sprint and 4 minutes of rest).

Methods. 28 recreationally active participants were pseudo-randomized into either a control group (CTRL) or training group (TR) and tested at 4 time points after baseline VO_2max testing. Participants were tested, pre-training/pre-fatigue, pre-training/post-fatigue, post-training/pre-fatigue, post-training/post-fatigue. The fatigue protocol was a SIT session (4 x 30-s sprints). The TR completed a 3-week running SIT protocol (3x/wk) progressing …

Structural Investigation Of Bcsc: Insight Into Periplasmic Transport During Cellulose Export, William Scott, Joel T. Weadge

Theses and Dissertations (Comprehensive)

A biofilm can be defined by a community of microbes coexisting within a self-produced protective polymeric matrix. Exopolysaccharide (EPS) is a key component in biofilms and a contributor to their virulence and pathogenicity. The cellulose bacterial synthesis complex is one such EPS system that is found in many Enterobacteriaceae,including Escherichia coli and Salmonella spp., and is responsible for the production and secretion of the EPS cellulose. BcsC is the periplasmic protein responsible for the export of the exopolysaccharide cellulose and was the focus of this research. Sequence homology comparisons and structural predictions between BcsC, and the previously characterized alginate …

Resign!!!: Acrimony And Protest On President Trump's @Realdonaldtrump Twitter Account, Saman Talib

Iowa Journal of Communication

A major feature of the Trump election and presidency is President Trump's use of Twitter. He has used @realdonaldtrump, his personal Twitter account, to state policy positions, berate various people, and even announce firings. While news coverage focuses on President Trump's tweets, the account itself has been and continues to be the recipient of copious numbers of negative posts from ordinary citizens. The court 's designation of this Twitter account as a 'designated public space' and the large number of negative posts warrants a closer examination of these tweets. This study employed the grounded theory method to analyze the account …

The Rhetoric Of Rhetorical Reactance: Pork Producers' Responses To The Animal Activist Movement, Kathleen German, Adam Rottinghaus

Iowa Journal of Communication

Animal activists made inroads against the fur industry, laboratory research, veal production, and horse slaughter during the 1980s and 1990s. While pork producers were not directly targeted, they nevertheless reacted, perceiving a dire threat to their own industry and a bleak future for pork production. This fear was magnified by their sense that activists were supported by a broad population of non/armers who were naively susceptible to irrational and emotional appeals. This case study points out the complexity of public discourse rippling outward from the animal rights movement. As animal activists raised their voices against fur ranchers, animal researchers, and …

Why? Because I Like You: Effects Of Familiarity On Perceptions Of Media Trustworthiness, Stephanie G. Shartel Dunn

Iowa Journal of Communication

Familiarity and parasocial relationships (PSR) play a definitive role on perceptions of trustworthiness and credibility. In this study, the role PSR play in the evaluation of political commentators is tested. Research presented demonstrates familiarity and PSR allow commentators to cultivate perceptions of trustworthiness and overcome retraction/corrective messages. Findings suggest increased familiarity and higher PSR generate more positive message evaluations, higher assessments of source credibility, and increased likelihood of persuasion.

The Dilemma Of Being Colin Kaepernick: An Examination Of The #Takeaknee Protest Using Heider's Balance Theory, Ashley A. Hanna Edwards, M. Elizabeth Thorpe

Iowa Journal of Communication

Colin Kaepernick and the #takeaknee protest have been simultaneously criticized and praised. Critics argue that Kaepernick disrespects veterans and the country, while supporters suggest he is an advocate for social justice in the mistreatment of people of color, particularly by law enforcement. Beyond partisan politics, this paper shows that critics and supporters alike are evaluating Kaepernick's protest on the basis of perceived consistency between his identity and behavior. Drawing on Heider 's balance theory, we argue that individuals who focus on Kaepernick 's identity as a professional athlete will be critical of the protest because it is out of balance …

The Influence Of Goals On Sexual Initiation, Shawna Harris

Iowa Journal of Communication

In an effort to utilize theory to understand sexual communication, this study examined if the Goals-Plans-Actions Theory's conceptualization of goals would relate to the use of direct and indirect sexual initiation strategies. We surveyed 111 participants and asked them to identify the salient goals and strategies used when initiating sex with a partner. Although relational resource goals and identity goals were rated high, they had no effect on the use of direct or indirect initiation strategies. However, the primary goal of having sex and conversation management goals positively correlated with the use of direct and indirect initiation strategies.

Speaking For Another Polis, Rebecca Townsend

Iowa Journal of Communication

With the ending of the historic practice of town meeting legislature in Amherst, Massachusetts in 2018, this essay studies one practice that had been a source of tension: the deliberative body's foreign policy rhetoric. This essay examines one deliberation on a resolution concerning Nigeria for how participants use presence (Perelman & Olbrechts-Tyteca, 1971) and ventriloquism (Cooren, 2016) to construct a sense of authority for speaking for themselves and for others as democratic agents. It contributes to literature on public meetings and on rhetorical authority.

Making The Case: A College Physical And Mental Health Integration, Tamara L. Laursen

Iowa Journal of Communication

Much research has been done linking physical disorders and depressive disorders. Although this topic is highly relevant to college populations, administrative structures and clinical practices vary as to how college health, health promotion, and counseling services are delivered. Understanding current operational relationships and possible strengths and weaknesses of an integrated physical and mental health service can provide notable benefits for college students. Recognized standards exist for college health services, health promotion, and counseling services. Exploration of current integrated models offers an understanding of benefits and challenges encountered when establishing an integrated model. Health and well-being are life-long endeavors, and by …

Resting Cerebral Blood Flow After Exercise Training In Mild Cognitive Impairment, Alfonso J. Alfini, Lauren R. Weiss, Kristy A. Nielson, Matthew D. Verber, J. Carson Smith

Psychology Faculty Research and Publications

Background:

Exercise training has been associated with greater cerebral blood flow (CBF) in cognitively normal older adults (CN). Alterations in CBF, including compensatory perfusion in the prefrontal cortex, may facilitate changes to the brain’s neural infrastructure.

Objective:

To examine the effects of a 12-week aerobic exercise intervention on resting CBF and cognition in CN and those with mild cognitive impairment (MCI). We hypothesized individuals with MCI (vs. CN) would exhibit greater whole brain CBF at baseline and that exercise would mitigate these differences. We also expected CBF changes to parallel cognitive improvements.

Methods:

Before and after a 12-week exercise intervention, …

Exploring Action Coils For Bystander Intervention: Modeling Bystander Consequences, Victoria Banyard, Elizabeth Moschella, Ernest N. Jouriles, John H. Grych

Psychology Faculty Research and Publications

Objective: Individuals who take action to reduce sexual assault can experience a range of positive and negative consequences as a result of helping. This study examined how different types of consequences explain variation in confidence and intent to help. Participants: Nine hundred sixty-six individuals who reported intervening in a situation involving interpersonal violence; approximately half were recruited from university psychology courses and half through Amazon’s Mechanical Turk. Data were collected from September to December of 2016. Methods: Participants completed measures of consequences related to helping, bystander efficacy, and intent to help. Results: Positive reactions from victims and other individuals who …

Alcohol And Marijuana: Substitutes Or Complements And A Deeper Evaluation Of Marijuana Prohibition, Nicholas Andrew Brown

Honors Program Theses

This paper first looks to determine whether alcohol and marijuana are substitutes or complements. This economic relationship between alcohol and marijuana could influence policy decisions regarding marijuana’s legal status in the United States. My method is a meta study and evaluates the current literature on alcohol and marijuana’s economic connection. I find that more empirical research is needed before we can definitively say whether alcohol and marijuana are substitutes or complements. Second, the paper compares the prohibitions of alcohol and marijuana and gives reasons why the United States should learn from its experience during alcohol prohibition and legalize marijuana

Liability Design For Autonomous Vehicles And Human-Driven Vehicles: A Hierarchical Game-Theoretic Approach, Xuan Di, Xu Chen, Eric L. Talley

Faculty Scholarship

Autonomous vehicles (AVs) are inevitably entering our lives with potential benefits for improved traffic safety, mobility, and accessibility. However, AVs’ benefits also introduce a serious potential challenge, in the form of complex interactions with human-driven vehicles (HVs). The emergence of AVs introduces uncertainty in the behavior of human actors and in the impact of the AV manufacturer on autonomous driving design. This paper thus aims to investigate how AVs affect road safety and to design socially optimal liability rules in comparative negligence for AVs and human drivers. A unified game is developed, including a Nash game between human drivers, a …

The current model of corporate governance needs reform. There is mounting evidence that the practices of shareholder primacy drive company directors and executives to adopt the same short time horizon as financial markets. Pressure to meet the demands of the financial markets drives stock buybacks, excessive dividends and a failure to invest in productive capabilities. The result is a ‘tragedy of the horizon’, with corporations and their shareholders failing to consider environmental, social or even their own, long-term, economic sustainability.

With less than a decade left to address the threat of climate change, and with consensus emerging that businesses need …

Variation In Both Host Defense And Prior Herbivory Can Alter Plant-Vector-Virus Interactions, Xiaobin Shi, Evan L. Preisser, Baiming Liu, Huipeng Pan, Min Xiang, Wen Xie, Shaoli Wang, Qingjun Wu, Chuanyou Li, Yong Liu, Xuguo Zhou, Youjun Zhang

Biological Sciences Faculty Publications

Background:

While virus-vector-host interactions have been a major focus of both basic and applied ecological research, little is known about how different levels of plant defense interact with prior herbivory to affect these relationships. We used genetically-modified strains of tomato (Solanum lycopersicum) varying in the jasmonic acid (JA) plant defense pathways to explore how plant defense and prior herbivory affects a plant virus (tomato yellow leaf curl virus, ‘TYLCV’), its vector (the whitefly Bemisia tabaci MED), and the host.

Results:

Virus-free MED preferred low-JA over high-JA plants and had lower fitness on high-JA plants. Viruliferous MED preferred …

Analysis Of The Tcr Repertoire In Hiv-Exposed But Uninfected Infants, Benjamin Gabriel, Carey Medin, Jeremiah Alves, Ruth Nduati, Rose Kerubo Bosire, Dalton Wamalwa, Carey Farquhar, Grace John-Steward, Barbara L. Lohman-Payne

Cell and Molecular Biology Faculty Publications

Maternal human immunodeficiency virus (HIV) infection has been shown to leave profound and lasting impacts on the HIV-exposed uninfected (HEU) infant, including increased mortality and morbidity, immunological changes, and developmental delays compared to their HIV-unexposed (HU) counterparts. Exposure to HIV or antiretroviral therapy may influence immune development, which could increase morbidity and mortality. However, a direct link between the increased mortality and morbidity and the infant’s immune system has not been identified. To provide a global picture of the neonatal T cell repertoire in HEU versus HU infants, the diversity of the T cell receptor beta chain (TRB) expressed in …

Valuation Of The External Costs Of Unconventional Oil And Gas Development: The Critical Importance Of Mineral Rights Ownership, Andrew Boslett, Todd Guilfoos, Corey Lang

Environmental and Natural Resource Economics Faculty Publications

We quantify the externalities associated with unconventional oil and gas development using hedonic valuation. One complication in determining local impacts is that some but not all properties are unified with mineral rights, which enable the residents to financially benefit from drilling, and this information is typically unobserved by researchers. To overcome this issue, we exploit the mineral severance legacy of the homestead act extensions of the twentieth century to identify properties in western Colorado that do not have mineral rights and are therefore only impacted negatively by drilling. We find housing prices decline about 35% when drilling occurs within 1 …

Smart Growth At The Ballot Box: Understanding Voting On Affordable Housing And Land Management Referendums, Shanna Pearson-Merkowitz, Corey Lang

Political Science Faculty Publications

This study investigates voter decision-making on two smart-growth components: land preservation and affordable housing. We seek to understand how voters make concurrent decisions about unpaired smart-growth components at the ballot box. Previous studies of smart growth, affordable housing, and environmental preservation have focused primarily on describing the attitudes and traits of voters on these policies, utilize aggregate voting outcomes, or are case studies of single towns in which there is a fairly homogenous group of residents either supporting or opposing the policy. We draw on a unique data set to investigate the different covariates of attitudes for environmental preservation and …

Interpreting The Law Of The Sea ‘Regime Of Islands’: An Opportunity For Productive Us Leadership, Elizabeth Mendenhall

Marine Affairs Faculty Publications

This commentary describes an opportunity for clarification of the United Nations Convention on the Law of the Sea (UNCLOS) ‘regime of islands.’ It describes the growing need to authoritatively distinguish between islands, rocks, and artificial islands for the purpose of stabilizing claims to maritime territory. Sea level rise and island building activities in the South China Sea and elsewhere are increasing the pace at which new islands appear and existing islands disappear. This commentary proposes a two-part interpretation of UNCLOS, which (1) freezes the status of islands and rocks, and (2) asserts a practical distinction between ‘islands’ and ‘artificial islands.’ …

Institutional And Conceptual Barriers To Climate Change Adaptation For Coastal Cultural Heritage, Alanna Casey, Austin Becker

Marine Affairs Faculty Publications

Climate change is increasing the speed at which tangible coastal cultural heritage is changing in character or being lost through weathering, erosion, and inundation. Damages to coastal archeological sites, loss of access to historical sites, and the alteration of cultural landscapes will force changes in the way researchers can study sites, tourists can enjoy places, and descendant communities who have lived in particular areas for time immemorial, and local community members can utilize and relate to landscapes. In the USA, the National Park Service is a primary coastal cultural resource management organization. The National Park Service has been working on …

The Influence Of Plastic Bag Bans On Pro-Environmental Behaviors In Rhode Island Coastal Communities, Eva Touhey

Open Access Master's Theses

One of the greatest threats to the natural environment is marine debris pollution. Single-use plastics, one of many contributors to marine debris, are causing the greatest harm, affecting the well-being of humans and animals. In an effort to mitigate plastic pollution, environmental policies are implemented to reduce the availability of single-use plastic products to the consumer. This research looks explicitly at single-use plastic bag policies to see if implemented plastic bag bans promote pro-environmental behaviors and broader support for plastic bag policies. This study sampled two communities in Rhode Island, one with a single-use plastic bag ban, Middletown, and one …

Optimized Fishing Through Periodically Harvested Closures, Paul G. Carvalho, Stacy D. Jupiter, Fraser A. Januchowski-Hartley, Jordan Goetze, Joachim Claudet, Rebecca Weeks, Austin T. Humphries, Crow White

Fisheries, Animal and Veterinary Sciences Faculty Publications

1. Periodically harvested closures are a widespread, centuries‐old form of fisheries management that protects fish between pulse harvests and can generate high harvest efficiency by reducing fish wariness of fishing gear. However, the ability for periodic closures to also support high fisheries yields and healthy marine ecosystems is uncertain, despite increased promotion of periodic closures for managing fisheries and conserving ecosystems in the Indo‐Pacific.
2. We developed a bioeconomic fisheries model that considers changes in fish wariness, based on empirical field research, and quantified the extent to which periodic closures can simultaneously maximize harvest efficiency, fisheries yield and conservation of fish stocks. …

Social Learning And Communication With Threshold Uncertainty, Todd Guilfoos, Haoran Miao, Simona Trandafir, Emi Uchida

Environmental and Natural Resource Economics Faculty Publications

Using a threshold public bad game, we perform an experiment to test the effects of communication on coordination failure with various levels of threshold uncertainty. We apply two communication treatments to the coordination game: cheap talk between group members (unrestricted) and anonymous written communication from one generation of subjects to another (restricted). We find that the probability of groups coordinating and reaching the socially preferred equilibrium increases significantly with cheap talk and increases moderately with written communication. Repeated communication through cheap talk leads to a higher probability of achieving a set of payoff-dominant equilibria even in the face of threshold …

Assessing Consumer Preferences For Sustainability, Equity, And Welfare In The Aquarium Trade, Larynn Cutshaw

Open Access Master's Theses

Each year millions of fish and invertebrates are traded to support the home aquaria industry. Aquarium keeping is a popular hobby worldwide and the trade has the potential to provide socio-economic benefits to reef-adjacent communities while promoting environmental stewardship by consumers. However, current practices are negatively impacting the industry as the supply chain can be environmentally unsustainable and socially unequitable. Poor industry practices compromise the welfare of the organisms, leading to immense supply chain losses which exacerbate the sustainability and equity issues. Since the trade is demand-driven, consumers can play a role in addressing poor industry practices by using their …

The Burden Of Invisibility: A Case Study Of The Fisheries Crisis In Ghana, And Usaid/Ghana Sustainable Fisheries Management Project’S Gender Mainstreaming Strategy, Danielle Bilecki

Open Access Master's Theses

The Sustainable Fisheries Management Project’s primary goal is to create a more sustainable artisanal fishery in Ghana, in order to increase food security within the nation. One of SFMP’s strategies within this fisheries-based project was to implement a gender mainstreaming strategy in order to empower previously overlooked women stakeholders. This chapter will present the results of a study on the impacts of SFMP’s gender mainstreaming strategy on members of Ghana’s artisanal fisheries sector.

This study focuses on impacts primarily associated with fishers, fish processors, members of client and partner organizations, as well as the organizations themselves, and on the Ministry …
