Capacity And Kinetics Of Light‑Induced Cytochrome Oxidation In Intact Cells Of Photosynthetic Bacteria, Mariann Kis, James L. Smart, Péter Maróti

Faculty Publications - Department of Biological & Molecular Science

Light-induced oxidation of the reaction center dimer and periplasmic cytochromes was detected by fast kinetic difference absorption changes in intact cells of wild type and cytochrome mutants (cycA, cytC4 and pufC) of Rubrivivax gelatinosus and Rhodobacter sphaeroides. Constant illumination from a laser diode or trains of saturating flashes enabled the kinetic separation of acceptor and donor redox processes, and the electron contribution from the cyt bc1 complex via periplasmic cytochromes. Under continuous excitation, concentrations of oxidized cytochromes increased in three phases where light intensity, electron transfer rate and the number of reduced cytochromes were the rate liming steps, respectively. By …

Failure: A Heuristic Inquiry Of The Experience Of Failure Through A Nature Based Art Therapy Process, Lisa Manthe

Art Therapy | Doctoral Dissertations

The aim of this arts based study was to investigate the experience of failure during the dissertation process. Through a heuristic lens, its objective was to gain an understanding of the tacit experience of failure and the influence of a nature art based process on the understanding of failure. Failure is integral to the scientific method (Wang et al. 2019), enhancing understanding and teaching us valuable skills. Intentional engagement with our response to failure allows us to address and incorporate possibilities that are often unseen (Nelson et al., 2017). The art process illuminates tacit knowledge, unearthing creative solutions and untapped …

Formation Of Gold Nanoparticle Self-Assembling Films In Various Polymer Matrices For Sers Substrates, Ksenia A. Maleeva, Ilia E. Kaliya, Anton P. Tkach, Anton A. Babaev, Michail Baranov, Kevin Berwick, Tatiana S. Perova, Alexander V. Baranov, Kirill V. Bogdanov

Articles

Surface-enhanced Raman spectroscopy (SERS) is regarded as a versatile tool for studying the composition and structure of matter. This work has studied the preparation of a SERS substrate based on a self-assembling plasmonic nanoparticle film (SPF) in a polymer matrix. Several synthesis parameters for the SPF are investigated, including the size of the particles making up the film and the concentration and type of the self-assembling agent. The result of testing systems with different characteristics is discussed using a model substance (pseudo isocyaniniodide). These models can be useful in the study of biology and chemistry. Research results contain the optimal …

Investigating The Role Corynebacterium Matruchotii Has Within Supragingival Plaque Spatial Organization And Its Response To Oral Streptococci And Saliva, Eric Ganeto Almeida

Open Access Dissertations

Human supragingival plaque (SUPP) is a polymicrobial biofilm on the tooth surface above the gumline, comprised of ordered structures with spatial associations between specific bacterial taxa. Recent microscopy and microbiome data have suggested that some plaque structures are scaffolded by the abundant filamentous bacterium Corynebacterium matruchotii decorated with Streptococcus species. These taxa are able to make a reproducible structure known as the ‘Hedgehog’ model in vivo where Streptococcus species tend to form 'corncob' like structures around the terminal ends of C. matruchotii. As these species colocalize in vivo, we hypothesize that they also interact biochemically with one another. …

Submerged Independent Agencies, Brian D. Feinstein, Jennifer Nou

Public Law and Legal Theory Working Papers

Independent agencies are in the judicial crosshairs. Scholars criticize their efficacy—while still puzzling over how to define the form. By and large, this attention focuses on the top of the agency hierarchy, the extent to which agency heads are insulated from presidential control. What this perspective misses, however, is that power is also exercised by tenure-protected civil servants below. This phenomenon exists not because Congress has delegated them authority, but because executive branch actors have. Consequently, there exists another species of independent agency that requires a reckoning: call them “submerged independent agencies.” These entities are “agencies” because they wield discretionary …

Nys Bar Association Annual Meeting Lecture Outline: The New Environmental Rights In Ny’S Constitutional Bill Of Rights, Nicholas A. Robinson

Elisabeth Haub School of Law Faculty Publications

It is too easy this winter to miss the signature Human Rights event in New York, the overwhelming vote last November 4^th to recognizing the Human Right to the Environment. Competition for our attention is fierce: the Pandemic, political rivalries playing out in Washington, D.C., and angst about extreme weather events and other climate change impacts. So, I welcome this opportunity to illuminate the hope and promise of Article 1, Section 19 in New York’s Bill of Rights: “Each Person shall have a right to clean air and water, and a healthful environment.” Most New York lawyers have yet …

The Power Of Reciprocity: How The Confederated Salish & Kootenai Water Compact Illuminates A Path Toward Natural Resources Reconciliation, Michelle Bryan

Water Law Review

This article chronicles the negotiation and recent passage of the Confederated Salish & Kootenai Tribes Water Compact, which creates one of the most innovative water management regimes envisioned among sovereigns. The Compact's journey toward ratification is extraordinary, as the parties over the span of three decades worked to overcome historically entrenched racism and political opposition to craft a model that would provide enough water for all peoples and the fishery. Compounding the challenge, the Flathead Reservation itself contains vast swaths of checkerboard land held by non-Indians and a major federal irrigation project that has permanently altered the hydrograph of the …

Everything Is Bigger In Texas, Including The Need To Incentivize And Implement Innovative Decentralized Wastewater Treatment Systems As A Method Of Water Reuse, Haley Varnadoe

Water Law Review

Texas will need to adapt to a drier climate and reduced water supply in the 21st century as the negative hydrological effects of climate change continue. Rising temperatures will accelerate evaporation of surface water resources, which in turn both increases reliance on depletable groundwater resources and de creases the amount of surface water available for aquifer recharge. As a result, Texans who rely on either groundwater or surface water to meet their domestic water needs-particularly those in rural aid regions-may suffer as both quantities decrease in the coming decades. The practice of domestic water reuse presents one solution to a …

Comparing Trebouxia Diversity In Lichen Genera Sympatric With The Niebla Species Complex., Anthony Perugini, Louise A. Lewis, Zachary M. Muscavitch

Undergraduate Papers

Lichens are one of the most successful mutualisms on Earth. The ecology and distribution of lichen symbionts likely influences their association and genetic structure . Two sister genera of lichenized fungi Niebla and Vermilicinia are endemic to the fog deserts on the west coast of North America. Species of Trebouxia, a genus of green algae found worldwide, are the associated photobiont partners to the Niebla/Vermilicinia species complex. Recent work demonstrated that Niebla and Vermilicinia are highly specific for only a few closely related Trebouxia molecular species (OTUs). This project examines the diversity and broad specificity of algae with lichen …

Decapod Sentience: Broadening The Framework, Cecilia De Souza Valente

Animal Sentience

A framework for studying sentience in decapods is of great value, but how high a cost (in suffering) to each individual decapod (or any animal) is warranted for collecting scientific evidence of sentience? The lack of evidence for some of the target article’s proposed criteria surely results from the fact that research is focused mainly on biomedical studies, ecotoxicology, and commercial production, with decapod sentience and welfare seen as only a secondary research topic. I draw attention also to the possibility of a wider framework that includes all felt experiences, from suffering to pleasure.

Sentience In Decapods: Difficulties To Surmount, Michael L. Woodruff

Animal Sentience

In the target article Crump et al. present 8 criteria to assess whether decapods experience pain. Four of these -- sensory integration, motivational trade-offs, flexible self-protection, and associative learning -- could be used to assess sentience in general. In this commentary I discuss difficulties with using these criteria to provide evidence of sentience in decapods, particularly if this evidence is to change public opinion and policies. These difficulties are lack of evidence, the potential to eventually explain the neurobiological basis of the behaviors chosen as criteria, thereby eliminating any explanatory work for sentience, and the reluctance to bring animals that …

Pain In Pleocyemata, But Not In Dendrobranchiata?, Gary Comstock

Animal Sentience

Crump et al.’s contribution to assessing whether decapods feel pain raises an important question: Is pain distributed unevenly across the order? The case for pain appears stronger in Pleocyemata than in Dendrobranchiata. Some studies report pain avoidance behaviors in Dendrobranchiata (Penaeidae) shrimp, but further studies are needed to determine whether the chemicals used are acting as analgesics to relieve pain, or as soporifics to reduce overall alertness. If the latter, the most farmed shrimp species may not require the same level of protection as crabs, crayfish, and lobsters.

Sentience As Part Of Emotional Lives, Frans B. M. De Waal

Animal Sentience

It is high time to explore the sentience of invertebrate animals, but this topic cannot be discussed without also exploring their emotional lives, including positive emotions. Sentience probably evolved to allow the regulation of emotions by endowing them with feelings.

Decapod Sentience: Promising Framework And Evidence, Jon Mallatt, Todd E. Feinberg Md

Animal Sentience

Strong points of the target article by Crump et al. are that it offers clear criteria for judging whether decapods are sentient, an effective semi-quantitative grading system for this purpose, and an astute, critical review of the literature. It concludes plausibly that major subgroups of decapods are sentient. A minor problem is that it includes classical, Pavlovian learning as a marker of sentience along with the more valid marker of complex (e.g., operant) learning. Another minor problem is that it does not distinguish results that are negative because of likely absence of sentience from results that are negative because they …

Extending The Null Hypothesis To Invertebrate Pain Sentience, Eva Kakrada, Michael Colombo

Animal Sentience

In 1985 Macphail proposed his Null Hypothesis that there were no qualitative differences in intelligence across vertebrate species. A recent review of the literature has found overwhelming support for his view. Studies also suggest that, with respect to cognition and the neural mechanisms that support it, the Null Hypothesis should be extended to invertebrates. We suggest, on the same premise, that the Null Hypothesis should be extended to pain sentience in invertebrates. Although few studies have been conducted, behavioural and neural evidence for pain sentience has been found in various representative invertebrate species.

Decapods As Food, Companions And Research Animals: Legal Impact Of Ascribing Sentience, Jonathan J. Cooper, Ambrose Tinarwo, Beth A. Ventura

Animal Sentience

This commentary provides an overview of the practical implications of attributing sentience to protect decapods as food, companion and research animals in the UK context. Recognising their capacity to suffer has implications for humane slaughter in farming and fishing sectors. It should also place a greater duty of care on owners of captive decapods, considering their needs and avoiding unnecessary suffering. The recognition of decapod sentience should also have an impact on their protection as research animals, although research with a potential to cause suffering may be needed to better understand decapods’ capacity to suffer.

A Framework For Evaluating Evidence Of Pain In Animals, Matilda Gibbons, Lars Chittka

Animal Sentience

Crump et al. define eight criteria indicating sentience in animals, with a focus on pain. Here, we point out the risk of false negative or false positive diagnoses of pain. Criteria of different levels of inclusivity are useful for using the precautionary principle in animal welfare considerations, and for more formal scientific evidence of pain. We suggest tightening the criteria -- from more general evidence of sentience to pain alone -- because crucial evidence for animal welfare decisions might otherwise be missed for animals subjected to invasive and injurious procedures.

Pros And Cons Of A Framework For Evaluating Potential Pain In Decapods, Robert W. Elwood

Animal Sentience

The rigorous framework for research into potential pain in decapods was successful in allowing legislators in the United Kingdom to evaluate a complex scientific issue. However, it might produce problems for research. I discuss doubts about the usefulness of the eight criteria. Some have yet to receive any investigation and others do not allow much inference about pain. In addition, some existing studies are not covered in the framework. Most worrying, however, is the potential for stifling future research of novel areas that are excluded from the framework.

Integrating Evolution Into The Study Of Animal Sentience, Walter Veit

Animal Sentience

Like many others, I see Crump et al. (2022) as a milestone for improving upon previous guidelines and for extending their framework to decapod crustaceans. Their proposal would benefit from a firm evolutionary foundation by adding the comparative measurement of life-history complexity as a ninth criterion for attributing sentience to nonhuman animals.

Animal Sentience Research: Synthesis And Proposals, Andrew Crump, Heather Browning, Alex Schnell, Charlotte Burn, Jonathan Birch

Animal Sentience

Most commentaries on our target article broadly support our approach to evaluating evidence of animal sentience. In this Response, we clarify the framework’s purpose and address criticisms of our criteria. A recurring theme is that a framework to synthesise current evidence of sentience is not the same as an agenda for future directions in animal sentience research. Although future directions are valuable, our framework aims to evaluate existing evidence and inform animal welfare legislation.

Factors Associated With The Hpv Vaccination Among Korean Americans And Koreans: A Systematic Review, Soojung Jo, Soo-Yeon Han, Connor A. Walters

School of Nursing Faculty Publications

Koreans and Korean Americans (KAs) have limited HPV knowledge and awareness. KAs share a culture with Koreans, and this culture has affected their behavior around HPV. This systematic review aimed to synthesize the factors associated with HPV vaccination among Koreans and KAs. The literature search was done with four databases. The vaccination rate, awareness and knowledge of HPV, and factors associated with vaccination intention were identified. Eighteen articles were selected. Koreans and KAs had low levels of HPV knowledge and awareness. Perceived benefits and seriousness were associated with vaccination intention. Cervical cancer history, beliefs that their daughters need a pap …

Effects Of Intervention And Prevention Programs On Youth Risk-Taking Behavior In Monroe County, Audrey D. Davis

Walden Dissertations and Doctoral Studies

Crime committed by adolescents between the ages of 13 and 16 is a recurring issue in the United States. Research showed a number of contributing factors associated with youth risk-taking behaviors and juvenile delinquency. The purpose of this qualitative case study was to improve the understanding of the relationship between intervention and prevention programs and curbing risk-taking and delinquency among adolescents between the ages of 13 and 16 in Monroe County, New York. This study addressed the connection between modern theories of deviance and programs of juvenile delinquency intervention as conceptualized by Chapman as the theoretical framework. Using intrinsic case …

Weight Management Among Postpartum African-Born Immigrant Women In Texas, Ethel Emehel

Walden Dissertations and Doctoral Studies

The growing population of postpartum African-born immigrant women has contributed significantly to the high burden of obesity and poor maternal health outcomes in the state of Texas; however, there is little research on this population. The purpose of this transcendental phenomenological study was to explore the lived experiences of weight management among postpartum African-born immigrant women in Texas based on the concepts of the health belief model. Semistructured interviews sparked the life experience of postpartum weight management of African-born immigrant women ages 18–45 who had a baby within the last year and suffered postpartum overweight or obesity. Interviews were audio-recorded …

Texas Metro Versus Nonmetro Variations In Cervical Cancer Preventative Measures, Amanda S. English

Walden Dissertations and Doctoral Studies

Cervical cancer is a public health threat that can be eliminated with the use of preventative measures. Individuals who live in Texas’s nonmetro areas are more likely than individuals who live in metro areas of Texas to be diagnosed with cervical cancer. In this study, the individual- and county-level factors in metro and nonmetro areas that facilitate or inhibit the receipt of cervical cancer preventative measures at multiple levels of influence were examined. The ecological model was used as the theoretical framework. Using secondary data from a national population health survey (n=1,303), the goal of this cross-sectional, quantitative study was …

Innate Property: The Danger Of Incongruency Between Law And The Biological And Behavioral Roots Of Property And Possessiveness, Aaron Schwabach

Cardozo Law Review de•novo

Property law is, in some areas, dangerously out of step with property expectations. Property—the idea that a place, object, or idea can belong to a person—is at the root of the world’s economies and thus also at the root of much of its laws. Property is neither solely a creature of positive law, nor of some abstract natural law with a moral underpinning, but rather may be biologically determined, much as Noam Chomsky proposed for languages in Aspects of the Theory of Syntax.1 The idea that ownership is at least behaviorally, and perhaps to some extent instinctively, determined has been …

Identifying Novel Subphenotypes In Covid-19 Using Protein Biomarkers, A Spicer, P A. Verhoef, C Lopez-Espina, A Bhargava, L Schmalz, M Sims, A V. Palagiri, K V. Iyer, M J. Crisp, A Halalau, N Maddens, A Espinosa

Conference Presentation Abstracts

RATIONALE: COVID-19 is widely heterogeneous in presentation, even across patients with similar demographics and medical history. Identification of subphenotypes based on host immune responses that are biologically discrete and predict outcomes may enable personalized COVID-19 therapies. Accordingly, using a composite of electronic health record (EHR) data and 36 research biomarkers, we sought to compare COVID-19 immune responses across patients of varying disease severity, identify subphenotypes within hospitalized COVID-19 patients, and test for heterogeneity of treatment effect (HTE) to intravenous corticosteroids across these subphenotypes. METHODS: In this multicenter retrospective analysis of prospectively collected data, patients presenting to three medical centers from …

Digital Accessibility In Iran: An Investigation Focusing On Iran's National Policies On Accessibility And Disability Support, Laleh Nourian, Kristen Shinohara, Garreth W. Tigwell

Articles

Digital accessibility has become an important topic in the field of HCI, but when looking at accessibility on a global scale, we find that the representation of accessibility research is mostly centered in the Global North with countries that are WEIRD (Western, Educated, Industrialized, Rich, and Democratic). Our paper explores digital accessibility in Iran, focusing exclusively on its national policies on accessibility. Iran is a non-WEIRD country located in the Global South, with no reports on its digital accessibility status from the Global Initiative for Inclusive Information and Communication Technologies (G3ict). We found that there is not enough focus on …

An Examination Of Diabetes Prevention Program Translations For Eastern Kentucky, William H. Robinson

DSW Capstone Projects

This capstone project examined translations of the National Diabetes Prevention Program (DPP) that have been adapted to improve cultural competency and analyzed the potential application of these adaptations to serve communities in Eastern Kentucky. Findings in the project were synthesized using the Ecological Validity Model (EVM) posited by Bernal et al. (1995) and the RE-AIM framework developed by Glasgow et al. (1999). EVM and RE-AIM have been used in other systematic literature reviews of the DPP and provide a framework for conceptual analysis and practice application of the findings. This project recommends changes in public health policy and social work …
