Investigation of PRA for Rapid Part Replacement
No full textAs the electronics industry transitions to using commercial-off-the-shelf (COTS) devices of increasingly smaller technologies, radiation effects analysis becomes more significant in mission planning. In this work a probabilistic risk assessment (PRA) program, RadSTATS, is used in the analysis of various COTS memories in a radiation environment. The probabilities that the bits in memory will be flipped due to single event upset (SEU) rates are calculated for each memory, volatile and non-volatile. The unavailability of bits was discovered to increase with increasing storage capacity. Methods of error detection and correction (EDAC) between the same manufacturer were seen to decrease at unavailability percent rates by a similar order of magnitude. Using the observed trends between memories, a Cypress flash with test data was used to help predict the unavailability of another Cypress flash without prior performed testing
Far from first kill: sapphic fan campaigns + the fight for queer television
Get PDFOver the decades, LGBTQ+ media has had a long history of, despite getting better, more popular, more powerful each time, being canceled, delayed, even simply never seen again. This has led to justified anger, sorrow, + distress from the queer fandom communities, who, already inspired by the sense of activism that their community is founded on, have created over 8 years of online fan campaigning to fight back, maybe even bring the shows from the grave to a new life. This case study will examine 6 of those campaigns, ranging from the birth of modern queer fandom in We Deserve Better, to the reinvention of the campaign in Fight for Wynonna, up to the present day First Kill Forever, among others. In the end, a success model will become apparent from the various wins + losses of each campaign, thus creating a blueprint from which future campaigns can pull
Effects of attractiveness and relationship type of perceptions of adolescent sexual grooming
No full textChild sexual grooming is a prevalent issue within the United States, especially with the rise of the internet and social media (Shakeshaft, 2004; Finkelhor et al., 2000; Winters et al., 2017). There has been less research done on adolescent sexual grooming; however, researchers have found that perceptions of adolescent sexual grooming vary depending on the gender and age of the offender and victim (Russel & Gyrus, 2022; Sahl & Keene, 2012). Researchers have found that people perceive a sexual grooming relationship as inflicting more harm if the perpetrator is a man (Hernandez et al., 2019), particularly an older man (Russel & Gyrus, 2022), or if the victim is younger (Hernandez et al., 2019). Research on adolescent sexual grooming has heavily revolved around educator sexual misconduct and online sexual grooming. Further, researchers have focused predominantly on the experiences of perpetrators and survivors, with limited focus on outsider perceptions, particularly for grooming relationships initiated by religious leaders or family friends. To address this gap, an experimental study will be conducted to understand how people’s perceptions of grooming behavior varies by levels of attractiveness and relationship with the victim. I hypothesize that adolescent sexual grooming will be perceived as less problematic when the offender is more attractive. I also hypothesize that a relationship with an obvious power imbalance, such as the offender being a religious leader, will be perceived as more problematic than a relationship with a more ambiguous power imbalance, such as the offender being a family friend. My first hypothesis was not supported. Level of attractiveness did not have a significant effect on perceptions of problematic behavior. My second hypothesis was supported. Relationship type did have a significant effect on perceptions of problematic behavior as respondents believed that victims would experience less harm in a relationship with a family friend than with a teacher or religious leader
Examining the adoption of digital transformation initiatives in higher education institutions: A mixed-methods investigation of employee perceptions and decision-making processes
Get PDFDigital transformation refers to the strategic integration of innovative technologies, which include mobile devices, artificial intelligence, and cloud computing, to name a few. These digital technologies weave into business processes to drastically enhance and ultimately improve the customer experience, optimize operational efficiency, or forge new revenue streams (Beach, 2021). This mixed-methods study investigated the dynamics of digital transformation in higher education from the perspective of information technology professionals. There were four primary research questions: • Research Question 1 (RQ1): Does one or more demographic factor predict an employee’s level of decision-making in higher education as it relates to digital transformation? • Research Question 2 (RQ1): What is the relationship between perceived organizational support and the decision-making process in higher education as it relates to digital transformation? • Research Question 3 (RQ1): What themes contribute to an employee\u27s negative or positive perceptions of their organization\u27s capacity for digital transformation? • Research Question 4 (RQ1): What challenges contribute to an organization\u27s agency for digital transformation initiatives? The quantitative portion of the study leveraged a survey instrument to collect data in five areas: demographics, general experience with digital transformation, sentiment and decision-making, work environment, and digital transformation efforts. Regression analysis determined a model of combined demographic information had no significance in predicting digital transformation decision-making, except with job roles. In addition, a Pearson’s correlation was performed between perceived support and digital transformation decision-making, resulting in a positive correlation between the two. Interviews were performed and analyzed through coding and categorizing, and they were evaluated for emergent themes. These findings highlighted the importance of administrators understanding and acknowledging the complexities of digital transformation by establishing supportive frameworks that empower IT professionals and non-IT staff across the organization. Potential recommendations include establishing funding specific for digital transformation, fostering a culture of collaboration, and promoting adaptability across the institution
Building a Dynamic Employee Value Proposition
Get PDFTalent survey data indicates 75% of active job seekers are likely to apply for a job if the employer activity manages its employer brand and their company’s Employee Value Proposition (EVP). Additional data confirms, organizations with a strong EVP have lower turnover and increased new hire commitments – addressing two of the most frustrating challenges facing employers today. A dynamic Employee Value Proposition is intentional and comprehensive in nature…capitalizing on the strengths of the organization and its purpose while providing benefits and resources that resonate with employees, enabling them to be productive and thrive. The stakes are high and so are employee expectations. Applying a combination of frameworks and real-world examples, this session aims to provide insight into steps an employer can take to create an EVP that helps to retain high-performing talent while solidifying and improving the relationship between employees and the organization. At the end of this session, participants will be able to: Explain the business case for developing an Employee Value Proposition Describe the essential elements of a magnetic EVP Outline initial steps an organization can take to integrate EVP into talent attraction and retention strateg
Investigating the Impact of Student SEL Education on Teacher Burnout, Satisfaction, and Well-Being
No full textThe importance of social and emotional learning (SEL) education in early education settings has become increasingly vital as mental health concerns in children are on the rise. While research focusing on the importance of SEL education in the mitigation of problem behaviors and mental health concerns in children has grown over the last decade, little research has explored the impact this SEL education has on teachers. As part of their job, teachers interact and engage with children daily as part of their workplace responsibilities. As burnout rates among educators continue to rise, due to increasing job demands and responsibilities, student SEL education that integrates teachers into the learning and skill development process has the potential to enhance educators\u27 work-life quality and overall well-being. As such, the proposed research seeks to investigate the impact student SEL education has on teacher reported burnout, job satisfaction, and well-being. Teachers whose students participate in SEL education will complete self-report measures of burnout, job satisfaction, and well-being throughout the academic year. Focus groups will also be conducted to gather feedback to better understand the specific elements of SEL currculum that may have an indirect effect on teachers’ wellbeing. We will analyze the quantitative comparison of means from the assessments given to teachers, along with a thematic analysis of the focus groups. As turnover in education continues to rise, it is imperative that wellbeing of teachers becomes a priority. Therefore, the importance of finding currciulum or SEL programming that is low-burden while also enhances teacher well-being, could possibly help reduce burnout and improve retention in a field that is crucial to children’s development
Beyond the Gig: Exploring Economic Viability, Underemployment, and Burnout in Gig Workers
Get PDFGig workers are susceptible to economic viability challenges, defined as the struggles faced by gig workers in maintaining financial stability, managing irregular income patterns, and securing consistent earnings (Ashford et al., 2018; Caza et al., 2022). There is limited literature examining the consequences of gig work viability challenges (Caza et al., 2021). The Conservation of Resources (COR) theory (Hobfoll, 1989) suggests that stress arises when resources such as finances and job security are threatened, lost, or fail to be gained (Hobfoll, 2011). Viability challenges represent a lack of these resources and the unpredictability of resource attainment. The ongoing pressure to manage these resources may increase burnout risk among gig workers. Burnout is described as a psychological condition characterized by physical and mental exhaustion of workers resulting from exposure to workplace stressors (Yang, 2023). In line with COR, we predict gig work viability challenges will be positively associated with burnout (H1). We further test underemployment as a moderator of this relationship. Underemployment refers to employment situations that underutilize an individual’s skills, qualifications, or working capacity (McKee-Ryan & Harvey, 2011). When gig workers perceive they are overqualified for the job, the frustration with their employment situation may exacerbate the burnout experienced from viability challenges. Thus, underemployment is expected to moderate the relationship such that the positive relationship will be stronger for gig workers experiencing higher levels of underemployment than those with lower levels of underemployment (H2). Participants were recruited through Amazon Mechanical Turk (N = 291). The cross-sectional survey measured gig work viability challenges (Caza et al., 2022), underemployment (Allan et al., 2017), burnout (Melamed et al., 1992), and control variables (age, gender, race, education). Using R Studio, we tested regression and moderation analysis. Both hypotheses were supported. For H1, viability challenges were positively associated with burnout (b = .42, p \u3c .001). For H2, underemployment moderated this relationship (b = .13, p = .004). The interaction term was significant, therefore simple slopes were tested using +/- 1SD from the mean. The relationship was significantly stronger for gig workers experiencing higher levels of underemployment (b = .55, p \u3c .001) than lower levels of underemployment (b = .29, p \u3c .001). Our findings advance theory by demonstrating that even in gig work contexts where viability challenges may be inherent to the job, the unpredictability of resource attainment induces burnout - especially for underemployed gig workers. For practice, gig employers should be more transparent regarding earnings to reduce viability challenges and minimize burnout
Effects of age and gender on perceptions on victims of financial exploitation
No full textA report by the Center for Victim Research shows that younger adults are more often victims of general and identity fraud (Irvin-Erickson & Ricks, 2019, p. 9); however, research conducted on financial exploitation focuses heavily on older adults. However, a recent study by Gunderson and colleagues (2021) found that older and younger adults are highly susceptible to financial exploitation. The purpose of the current study is to determine if perceptions of vulnerability to financial exploitation vary by the age of the victim. A sample of undergraduate participants will be recruited from the University of Tennessee at Chattanooga through an online recruitment system called SONA. Participants will be randomly assigned to one of four vignettes where gender and age have been manipulated and dichotomized: (1) 67-year-old older man victim, (2) 67-year-old older woman victim, (3) 20-year-old young man victim, and (4) 20-year-old young woman victim. Participants will be asked to respond to questions regarding the following: (1) perceptions of vulnerability and susceptibility, (2) perceptions of blame and accountability, and (3) perceptions of empathy and support. The hypothesis is that age and gender will interact such that older women will be perceived as more vulnerable and deserving of empathy and support. The results of this study will begin to lay the groundwork needed to understand how to decrease stigma to increase reporting, develop and market educational training to reduce financial exploitation that is targeted to adults across the lifespan, and improve training for legal and social service professionals
Screening full-sib and half-sib families of chestnut seedlings for resistance to Cryphonectria parasitica using a small stem assay and a leaf-disc assay
Get PDFCryphonectria parasitica is the ascomycete fungus species that causes chestnut blight disease. Symptoms of chestnut blight include bark cankers and eventually the death of American chestnut, Castanea dentata. However, not all Castanea species are equally affected by the disease, and some Asian species appear highly resistant. The OALDS and SSA in this study aim to assist in screening for resistance to C. parasitica within a year. We investigated the effect of C. parasitica on three North American species, one European species, four East Asian species of Castanea, and nine full-sib families of TACF backcross hybrids. Our study used both a small stem assay to measure canker lengths and an excised leaf disc assay to measure variation in tolerance to oxalic acid between the different Castanea species and hybrids. We inoculated 967 container-grown seedlings with C. parasitica strain EP155 and allowed cankers to develop for 12 weeks. Two measurements were recorded for each canker: orange zone and full length of necrosis, following the method of Cipollini et al. 2021. Excised leaf discs were soaked in a 50 mM solution of OA for 8 hours and then digitally imaged for measurement of browning with Image J, following the method of Harden 2023. Results show differences that vary by Castanea species in resistance to C. parasitica, as measured by orange zone in the SSA was significant between species. OA degradation (browning) did not have any statistically significant results. While the initial results seemed promising, the statistical analysis did not show any significance. These methods may continue to be practiced but should not fully replace the traditional method for C. parasitica resistance screening
Can jury instructions reduce the negative impact of pretrial publicity?
Get PDFThe increasing prevalence of pretrial publicity (PTP), media coverage of a case that occurs prior to a trial, raises concerns about fair trials. Jurors may rely on pretrial information rather than trial information to decide the fate of a defendant and may even confuse the sources of the information. While it is difficult to limit jurors’ exposure to PTP, jury instructions to improve memory for trial information may limit these effects. Participants (N=100) read negative PTP articles about a defendant. A week later, they were randomly assigned to jury instruction conditions (notetaking, question-posing, or standard) and watched a trial video about the case. Mock jurors who took notes and asked questions during the trial video were significantly better at remembering trial statements and attributing trial and pretrial information to its source than jurors who received standard instructions. However, instruction condition did not influence the number of guilty verdicts rendered
