    The relationship between autism and suicide: Risk factors and potential mitigation strategies

    Get PDF
    Suicide is a major problem worldwide, but individuals with autism may be at particular risk due to multiple factors—perceived burdensomeness, thwarted belonging, and capability for suicide, according to the IPTS model for suicidality as modified by Pelton and Cassidy (2017). This article focuses on these three factors and proposes a new feature of the model: the intersection between perceived burdensomeness and thwarted belonging. Existing suicide support mechanisms for young adults with autism without intellectual disability that target the main components of the model will be critiqued, and areas for further improvement will be suggested. Potential areas for future inquiry may include interdisciplinary collaboration between the autism community and researchers to identify the causes of suicide among autistic people, implement autism-specific risk assessment and suicide prevention tools, and educate clinicians and the general public about autism and suicide

    A study of the impact of the Nation Builders Program on the self-perception of African American male participants in the fourth and fifth grades at Dunbar Elementary

    This study was designed to determine if there was a significant difference in the self-perception of fourth and fifth grade African American male participants in the Nation Builders Leadership Program and fourth and fifth grade African American male participants in traditional extracurricular programs offered at Paul Laurence Dunbar Elementary School. The availability sample included 30 African American males. Fifteen participants were randomly assigned to the Nation Builders Leadership Program and fifteen were randomly assigned to other programs by the school’s administration. The participants selected were given the self-perception profile family of assessments (SPPC) designed by Dr. Susan Harter. The SPPC was given as a pretest and posttest to assess each participant’s self-perception in six dimensions: scholastic competence, social competence, athletic competence, physical appearance, behavioral conduct, and global self-worth. The dependent variable was the scores on the SPPC. This quantitative instrument was given before and after the students’ engagement in the programs to ascertain the programs\u27 relationships with their self-perception. The findings of the study seem to suggest that there is a significant difference in the self-perception of Nation Builders program participants and the self-perception of traditional program participants, as measured by the Harter SPP

    Decades of Don Quixote: tracking social progression through Marcela and Grisóstomo

    Get PDF
    In this essay, I will track the evolution of academic opinions in the late 20th and early 21st century of two main components of the episode: Marcela’s character and what it says about Cervantes’ perception of women’s autonomy, as well as Grisóstomo’s death and the rejection of the notion of suicide by past academics. Marcela’s dramatic rejection of societal demands and Gristósomo’s tragic and confusing death are radically exciting since there is so much left to be assumed about the two main characters that is not explicitly written. The story relies on irony and subversion to enunciate a certain message; this means that, inevitably, the message will be read differently by each reader. By tracing the episode’s critical attention, it becomes clear that Cervantes has made the themes in Don Quixote timelessly liable to interpretation; of course, this doesn’t mean that there isn’t a consensus on the meaning of the story today. Generally, most readers of Marcela’s story can agree that Cervantes has made it clear that Grisóstomo committed suicide; there has also been a sharp decline in the amount of papers published crticizing Marcela’s attitude, and a steady growth of papers instead recognizing Marcela as a pioneer of the independent woman. The ambiguity of the story, alongside the bucolic atmosphere, the parodic nature of the text, and the question of love and honor through Marcela and Gristóstomo’s actions have cemented this story into persistent cultural relevance and discussion

    My Internship Overview Poster reflects my experiences as an HR Intern for SPI LLC during the summer of 2023. I acquired this internship through a posting on Indeed and subsequent meetings/interviews. Specialty Products and Insulation (SPI) LLC is a company that fabricates, manufactures, and distributes insulation and related products. During my time at SPI, I had the opportunity to demonstrate my knowledge and skills by designing a comprehensive onboarding program for their new hires. This internship experience helped me better develop my business acumen, data analysis skills, communication, time-management skills, and attention to detail. Two of my biggest take-aways was the importance of benchmark data and not to be scared of sharing my ideas

    Justice perceptions, quiet quitting & personality

    Get PDF
    Quiet quitting is a term that has grown in popularity over the past few years. Quiet quitting can refer to a decrease in employees’ commitment to carry out assigned tasks, avoiding tasks that are not within employees’ job description, quitting the idea of going above and beyond in their job performance (Formica & Sfodera 2022) & (Rosalsky & Selyukh 2022). In the past, researcher have shown the relationship between engagement and burnout with personality. Since quiet quitting has only recently grown popular, the relationship between quiet quitting and personality has not been greatly researched. This thesis attempts to fill this gap by aiming to determine if personality is a predictor for quiet quitting in response to organizational injustice. The primary research question for this study asks if personality predicts quiet quitting in response to organizational injustice. There are five hypotheses included in this study that suggest a relationship between quiet quitting and the factors of the Big Five Inventory (BFI): agreeableness, neuroticism, conscientiousness, openness, and extraversion. The proposed method for this study is to collect participants by mass emailing MTSU students. Then, each participant will be asked to complete a demographics questionnaire, a work injustice scenario survey, a quiet quitting scale, and the BFI. The proposed analysis consists of using correlational analysis to determine the relationship between quiet quitting and personality in response to organizational injustice. Anticipated results include extroversion, conscientiousness, and neuroticism being related to quiet quitting. However, openness and agreeableness are not expected to be related to quiet quitting. The implications of this study relate to the 2023 RCIO theme. If quiet quitting is related to personality, organizations can use personality assessments to assist in their screening process. This will help organizations select talented individuals who are less prone to quiet quitting. If this study shows quiet quitting is related to organizational injustice, then this study reinforces the importance of creating a healthy work environment that will be more attractive to talent

    Propagation of wild-collected Prunus americana Marsh. by rooted cuttings for germplasm conservation in the Southern Appalachians

    Get PDF
    American plum, Prunus americana Marsh., is a native tree valued for wildlife and wildland restoration. To propagate this tree for germplasm conservation, this study investigated the optimal season of collection and indole-3-butyric acid (IBA) treatment for a viable rooted stem-cutting method. Cuttings were collected from trees in eight locations in May, July, and September, treated with 0-ppm, 1000-ppm, 3000-ppm, or 8000-ppm IBA for five seconds, and held in a mist propagation bed with basal heat for four to six weeks. The results of this study show that (1) rooted cuttings are a viable propagation method for wild-collected American plum, (2) rooting was greatest for May- or July-collected cuttings treated with 3000-ppm or 8000-ppm IBA, (3) cuttings treated with 8000-ppm IBA produced the most roots, (4) May-collected rooted cuttings had greater survival that July or September rooted cuttings, and (5) shoot length was longer for May-collected cuttings treated with 8000-ppm IBA

    The effects of outdoor therapy on depression and anxiety: a quantitative review

    Get PDF
    The goal of this research was to assess the effectiveness of outdoor therapy on depression and anxiety across different moderators via a quantitative review. While there are studies that look at the effectiveness of outdoor therapy on psychological outcomes, there is a lack of synthesis of the research investigating moderators. A literature review was conducted and six studies were included in the analysis. Cohen’s d was calculated for each study. We examined the following moderators: intervention type, intervention duration, age, and outcome measurement. The effects of outdoor therapy were greater for anxiety (d=0.65, n=1215) than depression (d=0.43, n=115). Within the anxiety results, the average effect size for adolescents (d=0.75, n=979) was greater than the adult effect size (d=0.27, n=236)

    The Innocent Bystander: A Scenario Based Study on the Impact of Leadership Gossip

    Get PDF
    The purpose of this study was to understand how witnessing workplace gossip between a supervisor and an employee in a hypothetical scenario impacts ratings of acceptability of gossip behavior, leader quality ratings, relationship quality, and future comfort with the leader. Data were gathered from 207 college students who read a scenario involving gossip, which varied in the target (about oneself or another) and the domain (about work or personal matters) and then responded to a series of questions about the scenario. Across all four scenarios, leaders received fairly unfavorable ratings for participating in gossip behavior. However, we did not find consistent main effects based on the target or domain and there were no significant interactions between domain and target. Limitations and practical implications are further discussed

    Reliable Change in College Coursework Self-Efficacy

    Get PDF
    This study aimed to examine the test-retest reliability of the College Self-Efficacy Inventory-Coursework subscale (CSEI-C) and calculate cutoffs for determining reliable change. A sample of 39 college students from a U.S. university (M=19.0±1.0 years old, 84.6% women, 64.1% White) completed the CSEI-C twice (test-retest interval: M=55.4±12.4 days). The CSEI-C had good test-retest reliability, per the intraclass correlation (ICC=.85). The cutoffs of detecting reliable change were ±.91, ±1.12, and ±1.44 for 70%, 80%, and 90% confidence intervals, respectively. College students often experience mental health problems, and those presenting for psychotherapy may experience concurrent reductions in academic self-efficacy. Clinicians could use the CSEI-C during treatment to track academic self-efficacy and determine whether treatment improves confidence in coursework – a meaningful functional outcome for college students

    Mobile phone mindfulness: Effects of app-based meditation intervention on stress and HRV of undergraduate students

    Get PDF
    Since the COVID-19 pandemic, stress has increased exponentially in undergraduate populations. The current study sought to determine the efficacy of an eight-week relaxation intervention, using a free meditation app to reduce perceived stress and increase baseline heart rate variability (HRV) of undergraduate students, compared to using a traditional relaxation intervention across the same period. Participants (N = 14) were randomized into either a meditation app group or self-directed diaphragmatic breathing group and were instructed to engage in their respective relaxation technique ten minutes daily for eight weeks. Pre- and post-intervention differences in perceived stress and HRV were examined, along with user satisfaction with the type of intervention. Perceived stress was significantly reduced in both groups. However, participants used the meditation app for a comparatively longer period of time and enjoyed the meditation app more than diaphragmatic breathing exercises. While there was no change in baseline HRV for either group, the percent change in HRV was significantly higher in the meditation app group. The results highlight the effectiveness of mobile phone meditation apps in reducing perceived stress in college students and suggest the app may be better at maintaining adherence amongst users when compared to traditional self-guided methods
