    Some Level of Skill for Life : Secondary Teacher Librarians Supporting Student Information Literacy Skill Transfer Beyond Secondary School

    No full text
    Students entering higher education are expected to transfer information literacy skills and knowledge developed through their primary schooling and sharpened in their secondary years. However, the constant evolution of the information landscape means the mastery of these skills presents challenges for students to develop and teachers to teach. Through interviews, this phenomenological study examines the perspectives and practices of 19 Australian secondary teacher librarians supporting student information literacy skill transfer in school and life contexts and considers important changes in the teaching of these skills. Findings suggest time and content overload are preventing integration across subjects and limiting students’ ability to apply skills in real world situations. Further, participants identified changes in important ethical issues around information like copyright and intellectual property, especially for students entering university. Potential solutions to these challenges include the adoption of whole-school or state-wide approaches to information literacy and partnerships with secondary schools and universities

    Examining the Anxiolytic Effects of Flavonoids in Passionflower: A Gut-Brain Axis Perspective

    No full text
    This literature review investigates the influence of Passiflora incarnata on the Gut-Brain Axis, focusing on the role of flavonoids and the specific biological mechanisms involved in this process. The study aims to identify Passiflora incarnata as a practical, non-harmful, and cost-effective alternative to current modern anxiety medications. This study also emphasizes the need for further clinical trials to integrate Passiflora incarnata further into healthcare settings. Using a narrative review approach, this analysis will examine pre-existing empirical articles, all of which have been found on credible sites, are peer-reviewed, and have been published within the past twenty-five years. The data discussed in this review will be analyzed to determine if the hypothesized relationships exist and their practical significance. If supported, the hypothesis validates the theory that Passiflora incarnata alleviates anxiety in part by modulating the Gut-Brain Axis, emphasizing the need for further clinical investigations

    American Consumer Culture and Social Media Polarization: Analyzing Twentieth Century Trends and Their Effects on Twenty First Century Politics

    No full text
    The emergence of social media as a mainstream communication technology during the early twenty first century has had an outsized impact on the United States\u27 political system. By analyzing trends in American culture and economics beginning in the decades following the end of World War Two, the circumstances that shaped social media during its development can be tied to long term historical changes. Shifts away from traditional models of community and towards rising individualism reshaped communication with both political allies and opponents. Generational shifts in political attitudes have heightened these divisions as well, as younger and liberal perspectives challenge traditional, conservative norms. Economic priorities have also shifted during this time period, incentivizing short term gain over longer term sustainability. As economic precarity and inequality increase, individuals increasingly look to narratives that support their worldview. The structure of corporate social media services looks to increase revenue rather than promote factual content. While these individuals have been aligning themselves at an increasing rate since 1945, contemporary political polarization has been accelerating since the introduction and mass adoption of social media in the first decades of the twenty first century. The shift from earlier political segregation along geographic divisions to modern polarization in digital communication has reshaped political communication by connecting previously isolated information environments. Social media\u27s impact on contemporary political events can be analyzed by examining how polarized perspectives on the outcome of the 2020 presidential election led to the unprecedented January 6 Capitol Riot

    What is Known About the Psychological Impacts of Acting, and Where Are the Gaps?

    No full text
    Acting has been a profession since before 400 BCE, and still is to this day through theater, television shows, movies, voice acting, and more. While studies consider the impact of acting on the audience, there are significant gaps of information for the psychological impacts this profession has. This thesis conducts a literature review of topics such as pretend play, role-play, drama therapy, and acting, to examine what is known about the topic, and a thematic analysis of fifteen publicly available interviews with a total of twenty-two actors to investigate what is known of the experience of actors. Six themes highlighted include getting into character, short and long-term impacts, social bonds, self-care, and safety concerns. Overall, we can see that the profession of acting seems to have an impact on the mental health of actors, with further research being required to investigate what variables have the most impact and why

    The Influence of Ethnic Racial Identity on the Critical Consciousness of Asian American College Students

    No full text
    Ethical and racial identity (ERI) and critical consciousness play crucial roles in how youth of color understand themselves, contextualize their racialized experiences, and navigate oppressive social conditions. However, there has been a lack of research on both constructs in the lives of Asian American youth. Thus, this thesis aims to study the influence of ERI on the critical consciousness of Asian American college students by conducting semi-structured interviews. ERI was found to influence critical reflection and critical action but not political efficacy. The relationship between ERI and critical consciousness is understood through how youth engage with their ERI and contextualize their experiences as Asian Americans. Understanding the unique racialized experiences of Asian American youth can help us aid the development of critical consciousness and channel it as a tool for resistance and empowerment among Asian American youth

    Historicity and Axiology: Temporal Implications for Axiology

    No full text
    To develop the axiology of moral (or ethical) values, phenomenological analysis must look at temporality in a way that is unfamiliar to it. This way is through knowledge and experience of the actual historical past, from which it has been separated by the Heideggerian conception of historicity and its classical Husserlian analysis of time consciousness. The development of historical studies helps to make this possible. A simple sample model of the diachronesis of the awareness of ethical significance, value, and obligation is presented. It moves the analysis from a presentist focus to the field of experience in which subjects develop moral agency. Two concepts, historical phenomenology and interpersonal values-making, are advanced as the bases of a research program. It will amplify the potential of phenomenology to understand ethical goods such as empathy and will also encourage interactions of ethics, philosophy of history, and phenomenology. Keywords: empathy, ethics, historicity, moral philosophy, philosophy of history, philosophy of tim

    Population Genomic Investigation of the Oregon Slender Salamander (batrachoseps Wrighti) Reveals Suburban Populations Are Remnants, Not Recent Introductions

    No full text
    In the face of urbanization and anthropogenic change, some native species persist while others are lost. Understanding native populations, particularly in marginal habitat, can lend insights into the effects of habitat change. The Oregon Slender Salamander (Batrachoseps wrighti) is endemic to the late-successional forests of the Cascade Range in Oregon and has declined due to land use change. In 2007, several populations of the Oregon Slender Salamander were found within highly human-modified localities in the Portland Metropolitan Region. We investigate whether these, and other newly discovered suburban populations, represent remnant populations that persisted in the face of habitat change or if they were recently reintroduced to the area via human-assisted transport. We use ecological niche models to assess climatic suitability of the suburban localities and population genomic analyses to examine the relationship of these suburban populations to populations within forested habitats in the Oregon Cascade Range. We find that the suburban sites are marginally suitable for the Oregon Slender Salamander. Furthermore, these populations are genetically distinct from those in the Cascade Range and show a pattern of isolation-by-distance. Our results support the hypothesis that these populations are remnant populations rather than recent introductions and represent a unique evolutionary history

    How do Patient-Provider Relationships Affect Patient Satisfaction?

    No full text
    This article reviews studies on patient satisfaction within the U.S. healthcare system to investigate how physicians’ behavior influences patients’ reported quality of care. Medical negligence, neglect, and cognitive biases are identified from the reviewed literature as physician behaviors that affect the patient-provider relationship and patient satisfaction. Emphasizing patient satisfaction and involvement in their care as important considerations when evaluating patient-provider relationships, Lightspeed underscores how the complex dynamic between patient and provider–including physicians’ reported feeling of inadequate interpersonal skills and patients’ sensitivity to dismissive communication–contributes to reduced satisfaction rates. Lightspeed argues that increasing physician awareness of these factors that influence patient satisfaction, particularly awareness of cognitive bias and neglect, will improve patients’ reported quality of care. There is a need for future research to study patient-provider communication to inform interventions targeting improving physicians’ interactions with patients and increasing patient satisfaction

    Robust Contraction Decomposition for Minor-Free Graphs and Its Applications

    No full text
    We prove a robust contraction decomposition theorem for H-minor-free graphs, which states that given an H-minor-free graph G and an integer p, one can partition in polynomial time the vertices of G into p sets Z₁,… ,Z_p such that tw(G/(Z_i ⧵ Z\u27)) = O(p + |Z\u27|) for all i ∈ [p] and Z\u27 ⊆ Z_i. Here, tw(⋅) denotes the treewidth of a graph and G/(Z_i ⧵ Z\u27) denotes the graph obtained from G by contracting all edges with both endpoints in Z_i ⧵ Z\u27. Our result generalizes earlier results by Klein [SICOMP 2008] and Demaine et al. [STOC 2011] based on partitioning E(G), and some recent theorems for planar graphs by Marx et al. [SODA 2022], for bounded-genus graphs (more generally, almost-embeddable graphs) by Bandyapadhyay et al. [SODA 2022], and for unit-disk graphs by Bandyapadhyay et al. [SoCG 2022]. The robust contraction decomposition theorem directly results in parameterized algorithms with running time 2^{Õ(√k)} ⋅ n^{O(1)} or n^{O(√k)} for every vertex/edge deletion problems on H-minor-free graphs that can be formulated as Permutation CSP Deletion or 2-Conn Permutation CSP Deletion. Consequently, we obtain the first subexponential-time parameterized algorithms for Subset Feedback Vertex Set, Subset Odd Cycle Transversal, Subset Group Feedback Vertex Set, 2-Conn Component Order Connectivity on H-minor-free graphs. For other problems which already have subexponential-time parameterized algorithms on H-minor-free graphs (e.g., Odd Cycle Transversal, Vertex Multiway Cut, Vertex Multicut, etc.), our theorem gives much simpler algorithms of the same running time

    Navigating Sovereignty and Human Rights: A Legal Analysis of Palestinian Detention Under Israeli Jurisdiction in Comparison to International Law

    No full text
    This thesis examines whether Israeli detention practices of Palestinians conform to or contravene Israeli domestic legislation and international legal standards using a doctrinal legal analysis. This thesis evaluates six key areas through four hypotheses: the detention of minors, geographic disparities (particularly Gaza), administrative detention procedures, the use of military courts, due process violations, and detention conditions. While Israeli domestic law formally authorizes these practices, the analysis finds they routinely violate crucial international legal norms, including the ICCPR, CRC, CAT, and the Fourth Geneva Convention. The use of secret evidence, prolonged administrative detention without trial, and discriminatory legal frameworks undermines the right to a fair trial and protection against arbitrary detention. The conditions under which individuals are held, such as solitary confinement, instances of torture, and neglect of medical needs, significantly violate both international humanitarian laws and human rights norms. This thesis explores how the practices employed in Israeli detention, despite being legalized, contravene global obligations. It emphasizes the pressing need for legal reform, mechanisms for accountability, and adherence to international laws regarding the treatment of detainees
