Detection of Hybrid Optical Anapoles in Dielectric Microspheres
Get PDFNonradiating optical anapoles are special configurations of charge-current distributions that do not radiate. It was theoretically predicted that, for microspheres, electric and magnetic dipolar coefficients can simultaneously vanish by engineering the incident light, leading to the excitation of nonradiating hybrid optical anapoles. In this work, the experimental detection of hybrid optical anapoles in dielectric microspheres (TiO2) is reported using dual detection optical spectroscopy, developed to enable sequential measurement of forward and backward scattering under tightly-focused Gaussian beam (TFGB) illumination. The results show that the excitation of TiO2 microspheres (diameter, d ≈1 µm) under TFGB illumination leads to the appearance of scattering minima in both the forward and backward directions within specific wavelength ranges. These scattering minima are found to be due to vanishing electric and magnetic dipolar coefficients associated with hybrid optical anapoles. The ability to confine electromagnetic fields associated with hybrid optical anapoles can give rise to several novel optical phenomena and applications
The Toughest Job You\u27ll Ever Love : Identity Creation, Compartmentalization, and Belonging Among Queer Peace Corps Volunteers
Get PDFThe Peace Corps advertises that it accepts anyone, no matter their gender identity or sexual orientation; however, recruiters and staff ask volunteers to go back into the closet for their twenty-seven months of service due to the Peace Corps’ safety concerns about their volunteers being out in their host countries. Queer Peace Corps Volunteers (PCVs) answer the call to serve, accepting that it means they will need to keep their queer identities concealed for two years and three months. I conducted ethnographic interviews with ten people who have served or are currently serving in the Peace Corps and identify under the LGBTQ+ umbrella to learn how they navigated finding a sense of belonging during their service. In these semi-structured interviews, I chose not to define belonging for my participants, allowing them to define belonging for themselves. In these interviews, trends emerged regarding the creation of a Peace Corps identity, the compartmentalization of identities, and queer dating within the Peace Corps. I approached this research with an understanding of the queer Peace Corps experience, having served in Vanuatu in 2019, sensing that the Peace Corps’ training and policies impede the ability of queer volunteers to form genuine relationships with their host communities. The responses from my interview participants confirmed this suspicion. In this thesis, I argue that queer PCVs are compelled to create an entirely new identity to fit what is expected of them by the Peace Corps and their host communities, as a result of the conditioning experienced during Pre-Service Training. This can be especially disorienting for queer PCVs, leaving them to question the authenticity of the relationships they form with Host Country Nationals. This is a problem for both PCVs and the Peace Corps, since the second of Peace Corps’ three guiding goals is “to help promote a better understanding of Americans on the part of the peoples served” (Peace Corps 2025a), and forming cross-cultural connection is one of the main motivating factors for PCVs to serve. PCVs sign up to give twenty-seven months of their lives to serve host countries on behalf of the United States government under the condition that the Peace Corps support and protect them, but instead, queer PCVs are forced to evade Peace Corps staff to find safety and belonging on their own terms
Transformative Social Emotional Learning Practices and Instructional Engagement in the Kindergarten Classroom
Get PDFThe kindergarten teachers at Catalina Elementary School have identified a crucial issue: their students\u27 inability to self-regulate is impeding their learning and classroom engagement. The kindergarten team engages in ongoing professional learning with a focus on transformative social emotional learning. The teacher team explores whether on-going professional learning based in transformative social emotional core competencies impacts their direct instruction of transformative social emotional standards. Teachers further support implementation of the transformative social emotional core competencies using structured play-based activities. Following the on-going professional learning sessions, the teacher team would craft a whole group lesson and select an activity to embed into the structured play centers in the classroom. Teachers grappled with selecting appropriate lessons and activities because of their students’ independent learning levels. For most writing and reflection activities selected, multiple versions using various modalities were created to support student independence. Through their participation in ongoing professional learning, the teacher team sought to develop an understanding of transformative social emotional thinking and shift their instructional practices in the classroom
The Impact of Race on Police Officer Retention
No full textPolice officer retention has been identified as a significant challenge for agencies across the United States. Factors that influence officer attrition, the effects of attrition, and how police agencies can modify job conditions to mitigate the problem have received increasing research attention. However, examinations of the specific factors that may influence officers of color to leave the policing field as a career are comparatively limited. Retaining officers who are underrepresented in policing is particularly important, as increasing the diversity of departments is listed as an integral part of improved police-community relations. Drawing upon a survey of officers from eight police agencies across the United States, the current study examined how race impacts officers’ intentions to leave their career field. The results showed significant differences between Black and non-Black officers. Surprisingly, Black/African American officers were identified to express more job satisfaction and, at the same time, more likely to quit policing as a career. The study presents policy implications for how police agencies can reduce officer turnover, retain newly recruited minority officers, and foster diversity

Get PDFFor the 74th Annual Meeting, the Literacy Research Association (LRA) membership was invited to respond to the current moment characterized by “consistent systemic legislative and political efforts to thwart achievements in literacy research, pedagogical practices, curricula, diversity, equity, and cultural inclusions” (LRA, 2024, Conference Program, p. 2). Drawing on Congressman John Lewis\u27s invocation to “Never, ever be afraid to make some noise and get in good trouble, necessary trouble” (Discover UMES, 2014), LRA President Elect and 2024 Conference Chair, Fenice Boyd, called on the membership to consider what actions literacy scholars are best suited to take by considering, What research questions, design, and methodologies build capacity, agency, and sustainable literacy development for our participants and our scholarship? …[H]ow might literacy research—and researchers—empower teachers, students, parents/guardians, administrators, and community members to make “good trouble” and assert our right to engage, appraise, and critique oppressive literacy practices that emerge from politics? (LRA, 2024, p. 2)
Prioritization Among School Nurses: An Integrative Review of the Literature
Get PDFWith a median caseload of 750–1,000 clients, school nurses face setting-specific challenges involving multiple, competing demands. This necessitates effective prioritization to prevent missed opportunities to provide appropriate care. This integrative review synthesizes the current state of the literature related to prioritization among school nurses in the United States. Three themes were identified relating to prioritization among school nursing: knowledge, attitudes and values; self-efficacy and intention to act; and the nursing process. The prioritization behavior of school nurses can be facilitated by organizational and community collaboration and strong evidence-based practice recommendations. High workloads and inadequate resources among school nurses are the most consistently cited barriers to effective prioritization. Additional research on how to improve effective prioritization among school nurses for the improvement of population health outcomes is needed
Investigation of the Human Temporal Styloid Process as a Bony Indicator of Speech
Get PDFThe temporal styloid process in humans serves as an attachment point for the styloglossus, stylohyoid, and stylopharyngeus, which are involved in tongue movement and deglutition. I hypothesized that the length of the ossified styloid process in humans is the result of selection for increased musculature that would support tongue movements involved in speech. This hypothesis assumes that the relative length of the ossified temporal styloid process is unique to humans. A comparative analysis of the presence or absence of the temporal styloid process was conducted on ten genera of Old-World primates, and it was found that the length of this structure is not unique to humans but also exists in baboons. However, the consistency of the bilateral presence of an ossified temporal styloid process was observed to be unique in humans, perhaps due to cranial covariation and bipedal locomotion. In Papio, the styloid ligament, styloglossus, stylohyoid, and stylopharyngeus attach to the styloid process in a comparable manner to the human soft tissue articulations. This suggests that the ossified temporal styloid process that is present in humans and baboons could be a convergent evolutionary structure, therefore its presence does not concretely indicate a species’ capacity for speech
Lady Macbeth\u27s Maternity and Morality
Get PDFThis thesis explores the ways in which adaptations of Lady Macbeth from the seventeenth century to modern day have functioned to vilify or redeem Lady Macbeth based on her connection with her maternity as well as on the contextual, cultural, and political opinions surrounding both a woman’s place in society and the importance of maternity. This thesis examines William D’Avenant’s 1674 stage adaptation of Macbeth, Han Tae-Sook’s 1998 stage adaptation Lady Macbeth, and Lisa Klein’s 2009 novel adaptation Lady Macbeth’s Daughter to capture a range of cultures and the evolution of the character
AI: Initial Responses, More Questions
Get PDF[In the absence of an abstract the opening of the editorial is presented.] Librarians working in technical services have long had opportunities to automate portions of their work. Attitudes about doing so, however, have been mixed. Automation comes with enhanced needs for human-mediated quality control. With this long-standing and somewhat fraught relationship in mind, we began discussing the use of artificial intelligence (AI) and large language model (LLM) tools and their implications for writing and reviewing in Library Resources & Technical Services (LRTS) back in 2023
