Before Amplification: The Role Of Experts In The Dynamics Of The Social Attenuation And Amplification Of Risk, Lisbet Fjaeran, Kenneth Pettersen Gould, Rob Goble Jan 2024

Before Amplification: The Role Of Experts In The Dynamics Of The Social Attenuation And Amplification Of Risk, Lisbet Fjaeran, Kenneth Pettersen Gould, Rob Goble

Sustainability and Social Justice

In this article, we use system/network theory together with the social amplification of risk framework (SARF) to show how expert actors over time and across multiple events can contribute to social risk amplification and attenuation. The framework and the theory, in particular the concepts of risk emplacement and displacement, are employed in the analysis of an illustrative case related to the use of the feed additive, narasin, and provide explanations of how risks are part of continuously ongoing and dynamic social processes. By emphasizing the role of experts in such developments, connecting what happens in expert communities with the processing …

Not Just A Simple Survey: A Case Study Of Pitfalls In Interdisciplinary, Multiorganizational, Multinational Research For Development, Fleur B.M. Kilwinger, Cynthia Caron, Anne M. Reitveld, Ynte K. Van Dam

Sustainability and Social Justice

Surveys are common research methods in agricultural research for development. Despite the multitude of well-documented warnings for pitfalls in survey research, it appears challenging to avoid these in practice. We use a case study in agricultural research for development to illustrate what complicates survey research within an interdisciplinary, multiorganizational and multinational team. The survey research process, rather than the survey outcome, is our object of study. Using the Methodology of Interdisciplinary Research (MIR) framework we identify different steps within survey research. We overlay a technographic lens to understand “the making of a survey”. We thereby focus on the transformations made …

Finding pathways to more sustainable agriculture and resource use remains the most pressing challenge for Amazonian countries. Characterizing recent changes in the structure and types of agrarian production systems, this review identifies responses to deal with the challenges and opportunities to promote more sustainable production and extraction economies in the Amazon. While regional agriculture and resource economies rest on a rich diversity of producers, knowledge, and production systems, the expansion of agribusiness enterprises has come to dominate the distribution of subsidies, institutional support, and logistical infrastructure. These trends are associated with forest loss and degradation, pollution of waterways, pressures on …


Development Of A Measure Assessing Adolescent Aggression: The Aggressive Behavior Risk Assessment- Adolescent- Parent Report (Abra-A-Pr), Katherine Fallon Jan 2024

Development Of A Measure Assessing Adolescent Aggression: The Aggressive Behavior Risk Assessment- Adolescent- Parent Report (Abra-A-Pr), Katherine Fallon

College of Graduate Studies: Theses & Dissertations

Although parent-report scales for general behavioral difficulties and aggression (e.g., verbal and physical aggression) exist, there are currently no measures assessing sexual behaviors in this context. Commonly, parent-report measures provide a few items relevant to behavioral aggression, and items encompassing sexually aggressive behaviors are frequently vague and non-specific in the actions being committed by the adolescent. The primary purpose of this project was to develop a comprehensive and multifaceted parent-report measure for aggressive behavior in adolescents. Three separate studies were conducted to evaluate the psychometric properties of the measure. Exploratory (EFA) and confirmatory factor analysis (CFA) were used to investigate …

Sialylation As A Mechanism For Preferential Ligand Binding In Cfs1r, Eric J. Beaulaurier Jan 2024

Sialylation As A Mechanism For Preferential Ligand Binding In Cfs1r, Eric J. Beaulaurier

EWU Masters Thesis Collection

Macrophages are immune cells that help provide the first line of defense against a wide range of internal and external insults and create the bridge between innate and adaptive immune responses. When macrophage homeostasis is disrupted, disease states occur. Associated disease states include rheumatoid arthritis, Alzheimer’s disease, and multiple sclerosis. The survival and proliferation of macrophages is largely controlled by signaling through colony stimulating factor 1 receptor (CSF1R). Notably, this receptor can be activated by two non-homologous ligands, colony stimulating factor 1 (CSF1) and interleukin- 34 (IL-34). These two ligands are differentially required for macrophage homeostasis across body systems and …

The Elwha and Glines Canyon dams on the Elwha River, Washington, USA were removed between 2011 and 2014 after being in place for a century, and at the time were the largest dams ever removed. The resulting dewatering of Lake Aldwell, the reservoir of the Elwha dam, and Lake Mills, the reservoir of the Glines Canyon dam exposed over 270 hectares of land that had been submerged. While several studies have examined the revegetation of these drained reservoirs, none have gone beyond 5 years since dam removal. These studies found that sediment grain size and reservoir landform (valley walls, terraces …


Disability In Education From A Neurodiversity Standpoint: A Multi-Article Dissertation, Isabelle Kluge Jan 2024

Disability In Education From A Neurodiversity Standpoint: A Multi-Article Dissertation, Isabelle Kluge

Antioch University Dissertations & Theses

This theoretical multi-article dissertation is a broad examination of education, including trends in our school system, juvenile justice system, and cultural/media system to address the disproportionate targeted failure of students with disabilities from a neurodiversity standpoint. Research shows how our current education system is not the practice of freedom for all learners, but rather a reproductive practice that teaches forms of group-based privilege that results in the disproportionate outcome of school failure, oppression, and incarceration for students with disabilities. Creating liberatory learning spaces for neurodiverse students of all races must include challenging White supremacy, neurotypical superiority, and a standardized one-size-fits-all …

Exploring The Impact Of Early Adversity On Young Children With Autism, Kelsea M. Batista Jan 2024

Exploring The Impact Of Early Adversity On Young Children With Autism, Kelsea M. Batista

Antioch University Dissertations & Theses

This dissertation builds on a small but growing literature exploring the association between early adverse childhood experiences (ACEs) and children diagnosed with autism spectrum disorder (ASD). Research suggests that children with ASD are more likely to experience ACEs throughout their lifetime due to increased vulnerability to victimization and social communication deficits. Still, to date, there is scant research explicitly exploring the impact of ACEs on young children diagnosed with ASD. This study utilized a biopsychosocial framework to further examine whether a relationship exists between ACEs and ASD. The objectives of this study include: (a) to determine whether a relationship exists …


Spatial And Temporal Variation In Population Genetic Diversity In Seagrasses And The Implications For Resilience, Anna Maria Frouws Jan 2024

Spatial And Temporal Variation In Population Genetic Diversity In Seagrasses And The Implications For Resilience, Anna Maria Frouws

Theses: Doctorates and Masters

Seagrass ecosystems are highly productive and fulfil vital roles in the coastal environment as ecosystem engineers and keystone species. Unfortunately, anthropogenic pressures have resulted in a significant loss of seagrass habitat and associated ecosystem services. The complex and unpredictable nature of these pressures, and their increasing extent and intensity globally, makes resilience-based ecosystem management a valuable approach. Resilience-based management requires knowledge on processes enhancing ecosystem resilience and on actions supporting these processes. Genetic diversity, which is the allelic variation among individuals of a population, has been recognised as one of the pillars of resilient ecosystems. Genetic diversity within a population …

The Texas Heart Institute Journal

BACKGROUND: Valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) is quickly becoming a routine and effective means by which to treat degenerated bioprosthetic valves. A known complication of ViV-TAVI is patient-prosthesis mismatch, which substantially affects survival. Bioprosthetic valve fracture is a method by which to reduce the risk of patient-prosthesis mismatch and post-ViV-TAVI transvalvular gradients. This study sought to determine the safety and efficacy of post-ViV-TAVI bioprosthetic valve fracture.

METHODS: Patients with a history of surgical aortic valve replacement undergoing ViV-TAVI bioprosthetic valve fracture (N = 25) at the corresponding institution from 2015 to 2022 were cataloged for a retrospective analysis. …

Klebsiella Pneumoniae Carbapenemase Variant 44 Acquires Ceftazidime-Avibactam Resistance By Altering The Conformation Of Active-Site Loops, Zhizeng Sun, Hanfeng Lin, Liya Hu, Neetu Neetu, Banumathi Sankaran, Jin Wang, B V Venkataram Prasad, Timothy Palzkill

Faculty, Staff and Students Publications

Klebsiella pneumoniae carbapenemase 2 (KPC-2) is an important source of drug resistance as it can hydrolyze and inactivate virtually all β-lactam antibiotics. KPC-2 is potently inhibited by avibactam via formation of a reversible carbamyl linkage of the inhibitor with the catalytic serine of the enzyme. However, the use of avibactam in combination with ceftazidime (CAZ-AVI) has led to the emergence of CAZ-AVI-resistant variants of KPC-2 in clinical settings. One such variant, KPC-44, bears a 15 amino acid duplication in one of the active-site loops (270-loop). Here, we show that the KPC-44 variant exhibits higher catalytic efficiency in hydrolyzing ceftazidime, lower …

Sle1 and Faslpr are two lupus susceptibility loci that lead to manifestations of systemic lupus erythematosus. To evaluate the dosage effects of Faslpr in determining cellular and serological phenotypes associated with lupus, we developed a new C57BL/6 (B6) congenic lupus strain, B6.Sle1/Sle1.Faslpr/+ (Sle1homo.lprhet) and compared it with B6.Faslpr/lpr (lprhomo), B6.Sle1/Sle1 (Sle1homo), and B6.Sle1/Sle1.Faslpr/lpr (Sle1homo.lprhomo) strains. Whereas Sle1homo.lprhomo mice exhibited profound lymphoproliferation and early mortality, Sle1homo.lprhet mice had a lifespan comparable to B6 mice, with no evidence of splenomegaly or lymphadenopathy. Compared to B6 monogenic lupus strains, Sle1homo.lprhet mice exhibited significantly …


Adipose Tissue Lymphocytes And Obesity, Feng Gao, Benjamin Litchfield, Huaizhu Wu Jan 2024

Adipose Tissue Lymphocytes And Obesity, Feng Gao, Benjamin Litchfield, Huaizhu Wu

Faculty, Staff and Students Publications

Obesity is associated with chronic inflammation in adipose tissue (AT), mainly evidenced by infiltration and phenotypic changes of various types of immune cells. Macrophages are the major innate immune cells and represent the predominant immune cell population within AT. Lymphocytes, including T cells and B cells, are adaptive immune cells and constitute another important immune cell population in AT. In obesity, CD8+ effector memory T cells, CD4+ Th1 cells, and B2 cells are increased in AT and promote AT inflammation, while regulatory T cells and Th2 cells, which usually function as immune regulatory or type 2 inflammatory cells, are reduced …

We present the case of a 60-year-old male, with active smoking and cocaine use disorder, who reported progressive chest pain. Various anatomical and functional cardiac imaging, performed to further evaluate chest pain etiology, revealed changing severity and distribution of left main artery (LMA) stenosis, raising suspicion for vasospasm. Intracoronary nitroglycerin relieved the vasospasm, with resolution of the LMA pseudostenosis. A diagnosis of vasospastic angina (VA) led to starting appropriate medical therapy with lifestyle modification counselling. This case highlights VA, a frequently underdiagnosed etiology of angina pectoris. We discuss when to suspect VA, its appropriate work-up, and management.

Duncan NRI Faculty and Staff Publications

Background: A hereditary condition primarily affecting the kidneys and heart has newly been identified: the RRAGD-associated autosomal dominant kidney hypomagnesemia with cardiomyopathy (ADKH-RRAGD). This disorder is characterized by renal loss of magnesium and potassium, coupled with varying degrees of cardiac dysfunction. These range from arrhythmias to severe dilated cardiomyopathy, which may require heart transplantation. Mutations associated with RRAGD significantly disrupt the non-canonical branch of the mechanistic target of rapamycin complex 1 pathway. This disruption hinders the nuclear translocation and transcriptional activity of the transcription factor EB a crucial regulator of lysosomal and autophagic function.

Summary: All identified RRAGD variants compromise …
