User Research To Design A More-Than-Human Food Commons, Justin Sacks

DRS Biennial Conference Series

The way humans approach food systems not only affects our survival but also creates or destroys futures for humans and nonhuman species alike. Rooted in a rights-based approach, food as a commons offers an important and robust economic alternative to food as a commodity. The commons literature also struggles with anthropocentrism, however, particularly the recognized analytical frameworks used by scholars that classify nonhuman nature as inputs. How can user research tools support communities to create a more-than-human food commons that treats nonhuman nature as equal actants? This paper responds to this question by adapting two user research tools to support …

Why Would I Ever Fry And Eat My Scoby? It Would Be Like Murder! Attuning To Nonhumans Through Kombucha Fermentation Practices, Aybars Senyildiz, Emilija Veselova

DRS Biennial Conference Series

Kombucha fermentation is a multispecies activity guided by human-microbe interactions. This study investigates kombucha fermentation practices as a platform to recognize relationality with nonhuman microbes. For this, relational theories enable reframing human-microbe relations by focusing on reciprocity and interconnectedness within multispecies relations. The empirical research consists of interviews, a design probing task, and a collective reflection workshop with kombucha brewers. The empirical research delivers insights into the agency of microbes, sensory experiences, and embodied knowledge in kombucha fermentation practices. Findings investigate how humans attune to the needs of microbes, and the role of embeddedness in ethical doings. In this way, …

Designing Appropriate Things: An Experiential Perspective On The Effectiveness Of Artefacts In Contributing To Behaviour Change, Thomas Van Arkel, Nynke Tromp

DRS Biennial Conference Series

Behavioural design is an emergent discipline that aims to harness design’s influence on behaviour in an intentional way. However, there is limited knowledge on how to translate knowledge on behaviour and its determinants to specific design properties in ways that can maintain such change. We adopt a user experiential view to discuss the role that artefacts and their materiality play in effectively changing behaviour by introducing the notion of appropriateness, a quality of user-artefact interaction that describes the fitness of an artefact to the user and context that may play a moderating role in effectiveness of a design intervention in …

Reflection During Goal Setting: An Analysis Of Popular Personal Informatics Apps, Tina Ekhtiar, Rúben Gouveia, Armağan Karahanoğlu, Geke Ludden

DRS Biennial Conference Series

Setting achievable, realistic goals aligned to people’s current abilities and needs is an important part of behavior change. Reflection is a critical part of this process, as it helps people identify and elicit appropriate goals. Commercial applications that support behavior change often use goal setting; however, we know very little about if these implementations are based on theory and how they support reflection. In this paper, we analyze how popular health tracking apps support reflection during goal setting. We found that a majority supported limited or no reflection during the elicitation of goals. We discuss our findings and suggest design …

Healthricious: Improving An Existing Mobile App For Healthy Eating To Support Groups At Risk Of Covid-19, Sander Hermsen

DRS Biennial Conference Series

Urgent health issues, such as the COVID-19 pandemic, require rapid responses based on scientific evidence. Improving existing solutions is often faster, more effective and cheaper than developing new ones. This paper describes a case study consisting of a design cycle aimed at improving an existing design, a mobile app, to better support at-risk groups with healthy nutrition, to reduce risk of debilitating consequences of COVID-19. The design process consisted of five phases: user research (lived experience), expert consultations (learned experience), behavioural analysis of the original design, development of a new iteration, and delivery & evaluation. The case study showed that …

Associations Of Dietary Antioxidants With Glycated Hemoglobin And Insulin Sensitivity In Adults With And Without Type 1 Diabetes, Arpita Basu, Amy C. Alman, Janet K. Snell-Bergeon

Kinesiology and Nutrition Sciences Faculty Research

Type 1 diabetes (T1D) has been associated with increased risks of atherosclerotic cardiovascular disease, and poor glycemic control and oxidative stress play a major role in its pathology. There is a lack of data on the role of dietary antioxidant micronutrients, including vitamins and trace elements, in glycemic control in T1D. The aim of this study is to examine associations of dietary intakes of micronutrients with glycemic status. We report data from a cross-sectional analysis from the coronary artery calcification in type 1 diabetes (CACTI) study (n = 1257; T1D: n = 568; nondiabetic controls: n = 689) collected between …

Size Specific Boldness Associated With Differences In Resource Requirements And Habitat Use: A Cross-Sectional Study In Hermit Crabs, Mark Briffa, Rose Archer

School of Biological and Marine Sciences

Abstract Animal personality is often studied within compressed periods of observation that represent narrow windows in comparison to animal lifespans. While much is known about the relations between repeatable personality traits and cross-situational behavioural plasticity, less is known about how such traits might differ across age classes or life-history transitions. We conducted a cross-sectional study of startle response duration in three size classes of Pagurus bernhardus, the common European hermit crab. We defined size classes using transitions in the preferred species of gastropod shells that accompany growth, and this change in preference is in turn associated with a transition from …

Algorithmic Manipulation: How Social Media Is Shaping Our Theology, Ethan Jago

Liberty Theological Review

The average individual in Generation Z spends nine hours a day on social media and derives over 62% of the information retained from social applications such as YouTube and Instagram. Social media applications are designed to track and adapt a user's activity to custom-tailor their internet experience resulting in a controlled, one-sided view of the information flow custom-tailored to an individual's usage, which subtly changes the disposition concerning the interpretation of theological and biblical truths. The algorithm of social media responds adapts and directly impacts individuals in what they think, purchase, and places they visit. Social media is not neutral …

Variation On A Theme: The Structures And Biosynthesis Of Specialized Fatty Acid Natural Products In Plants, Samuel Scott, Edgar B. Cahoon, Lucas Busta

Department of Biochemistry: Faculty Publications

Plants are able to construct lineage-specific natural products from a wide array of their core metabolic pathways. Considerable progress has been made toward documenting and understanding, for example, phenylpropanoid natural products derived from phosphoenolpyruvate via the shikimate pathway, terpenoid compounds built using isopentyl pyrophosphate, and alkaloids generated by the extensive modification of amino acids. By comparison, natural products derived from fatty acids have received little attention, except for unusual fatty acids in seed oils and jasmonate-like oxylipins. However, scattered but numerous reports show that plants are able to generate many structurally diverse compounds from fatty acids, including some with highly …

Diet Recommendations For Patients With Irritable Bowel Syndrome, Tia M. Kinilau, Shawna Bajet, Erika Mccarthy, Justin Gambini

Doctor of Medical Science (DMSc)

Introduction

Irritable bowel syndrome (IBS) is a very common chronic functional gastrointestinal (GI) disease that is characterized by abdominal pain in association with defecation and change in bowel habits.1 The condition has a multifactorial and incompletely understood pathophysiology, including altered brain-gut interactions, microbiome changes, differed GI motility, psychological factors, and food hypersensitivity.2 With the heterogenicity of the disorder, there is no standardized treatment for IBS, leading its therapy to rely on symptomatic treatments.2 The influence of dietary triggers on the generation of IBS symptoms is well-known and includes different mechanisms including immune activation, mast cell inflammation, and luminal distention.2 Studies …

Bioelectrical Impedance Changes Of The Trunk Are Opposite The Limbs Following Acute Hydration Change, Dale R. Wagner

Kinesiology and Health Science Faculty Publications

This study aimed to evaluate the changes in impedance and estimates of body composition variables obtained from segmental multi-frequency bioelectrical impedance analysis (SMFBIA) following acute hydration change. All participants (N = 11 active adults) had SMFBIA measurements at baseline (euhydration), post-dehydration, and post-hyperhydration in an experimental repeated-measures design. Dehydration and hyperhydration trials were randomized with the opposite treatment given 24 h later. Dehydration was achieved via a heat chamber of 40 °C and 60% relative humidity. Hyperhydration was achieved by drinking lightly-salted water (30 mmol·L^-1 NaCl; 1.76 g NaCl·L^-1) within 30 min. Post-measurements were taken 30 min …

Comparing Brood Care Behaviors Across Five Fertility Castes In The Invasive Fire Ant,Solenopsis Invicta,And The Expression Of Inotocin, Alexis Masnjak

USF Tampa Graduate Theses and Dissertations

The fire ant, Solenopsis invicta, is one of the most successful of the invasive eusocial invertebrates. The fire ant’s prolific reproductive capacity and its division of labor among five fertility castes are key factors to its successful invasion and global colonization across all continents except Antarctica. Although the rate of self-care and brood care by sterile S. invicta workers is well known, little is known about the rate of self-care and brood care by the other four fertility castes. In this study, I quantified the frequency and duration of behaviors by alate males, alate queens, newly mated queens, older mature …

“Even If You Have Food In Your House, It Will Not Taste Sweet”: Central African Refugees’ Experiences Of Cultural Food Insecurity And Other Overlapping Insecurities In Tampa, Florida, Shaye Soifoine

USF Tampa Graduate Theses and Dissertations

In the United States, resettled African refugee populations experience food insecurity at rates up to seven times higher than those of the general population. In Tampa, Florida, anthropologists have documented high levels of food insecurity among Central African refugee households since members of this population began to be resettled in the area in 2016. Utilizing an intersectional lens and drawing upon theoretical concepts such as cultural food security, navigational capital, and social reproduction, this thesis examines how Central African refugees, particularly women, experience food (in)security and other overlapping forms of (in)security as they integrate into US systems of structural inequality …

BACKGROUND: Children with inflammatory bowel disease [IBD] are disproportionally affected by recurrent Clostridioides difficile infection [rCDI]. Although faecal microbiota transplantation [FMT] has been used with good efficacy in adults with IBD, little is known about outcomes associated with FMT in paediatric IBD.

METHODS: We performed a retrospective review of FMT at 20 paediatric centres in the USA from March 2012 to March 2020. Children with and without IBD were compared with determined differences in the efficacy of FMT for rCDI. In addition, children with IBD with and without a successful outcome were compared with determined predictors of success. Safety data …

Crispr/Cas13 Effectors Have Differing Extents Of Off-Target Effects That Limit Their Utility In Eukaryotic Cells, Yuxi Ai, Dongming Liang, Jeremy E Wilusz

Faculty, Staff and Students Publications

CRISPR/Cas13 effectors have garnered increasing attention as easily customizable tools for detecting and depleting RNAs of interest. Near perfect complementarity between a target RNA and the Cas13-associated guide RNA is required for activation of Cas13 ribonuclease activity. Nonetheless, the specificity of Cas13 effectors in eukaryotic cells has been debated as the Cas13 nuclease domains can be exposed on the enzyme surface, providing the potential for promiscuous cleavage of nearby RNAs (so-called collateral damage). Here, using co-transfection assays in Drosophila and human cells, we found that the off-target effects of RxCas13d, a commonly used Cas13 effector, can be as strong as …

Cleaning Invisible Matter In Open-Kitchen Restaurants To Reduce The Impact Of Covid-19, Bendegul Okumus

Rosen Research Review

Commercial cooking in indoor settings is known to produce particulate matter, a mixture of solid particles and liquid droplets which can cause acute or chronic respiratory problems. Recent studies suggest that these invisible particles also make people more susceptible to adverse health effects of the COVID-19 virus. Dr. Bendegul Okumus was joined by a team and conducted an experimental scientific study in an open-kitchen chain restaurant to determine whether the levels of particulate matter (PM) pollution were potentially harmful for both kitchen staff and customers dining at the restaurant.
