Student Success and Evaluation Metrics

In so many instances, students drift through high school and are unaware of what types of job opportunities are out there for them. It is easy to see that a student can get overwhelmed by the number of career options, or they may not know what they want to do at all. The Blue Barred has generated a solution that allows students to see their options much more clearly through the analysis of six factors and their contribution to success: Engagement, Value Added Learning, Network-ability, Literacy, Numeracy, and Graduation Rates. Through the usage of tools such as literary research, surveys, the House of Quality, a Pareto chart, and a Lingo code-based Optimization model, we were able to discover that amongst the defined six factors that contribute to maximizing the number of career opportunities, the student who sees the value in what they learn in school will have a much wider array of job opportunities from which to select. This also shows that schools should focus the most on value added learning to produce the most successful students

U.S. Public Opinion of Reproductive Control Options for Free-roaming Horses on Western Public Lands

Free-roaming horses (Equus ferus caballus; horses) inhabit public rangelands located primarily in 10 western U.S. states. Recent horse population increases are impacting rangeland ecosystems, native wildlife species and their habitats, and exacerbating conflicts with domestic livestock grazing. While contraceptives and physical sterilization are promising options to manage horse herd levels, public opinion concerning the use of fertility control is not well understood. To better inform policymakers, we completed a rigorous study of a random sample of public land stakeholders across the United States (n = 3,500) in 2020 using a Likert scale online survey to assess their level of agreement with the general use of reproductive controls and their preferences regarding 4 available reproductive control options. We used chi-square likelihood ratio tests to determine the associations between the knowledge of horse origins in North America and horse management in the United States, and public support of contraception and sterilization methods to control horse populations. We also assessed the associations between survey responses and respondent demographics. Most respondents either “somewhat agreed” or “strongly agreed” with the use of contraceptives to control horse birth rates (36.6% and 26.9%, respectively) when no specific type of contraceptive was described. Respondents who believed horses were native to North America “strongly agreed” with the statement regarding the use of contraceptives less often (22.2%) than respondents who recognized that European explorers introduced horses (36.6%) or believed horses arrived by crossing a land bridge (35.8%); however, this association exhibited very low power to predict the response (λ \u3c 0.1). Similarly, while there were some associations indicated by chi-square analyses between demographic variables and support for contraceptives, these associations exhibited very low power to explain the responses. When asked to rank 4 generalized population control options, more respondents ranked physical sterilization as their preferred option (37.1%). There was an association between age and ranking order of sterilization. For ages 18–53, the range was 40.6–45.3%, significantly more than older ages, 54 to ≥73, where the range was 31.1–33.8%. Knowledge did not influence the preference for control options. Our results suggest that our respondents were more supportive of the use of contraceptives or sterilization, when described in generalities, to control the birth rates in free-roaming horses. Our research provides policymakers with objective, novel insights into public knowledge and perceptions concerning the population control of free-roaming horses on designated western rangelands. We encourage the federal, state, and tribal agencies charged with the management of free-roaming horses to develop and deliver outreach programs to better educate public land stakeholders about the ecological and economic impacts of free-roaming horses on western landscapes and efficacy of available population management options to mitigate impact and sustain herds

“Say it Loud, I’m Black and Proud:” The Effectiveness of Racial Acknowledgments at Work

Research underscores engagement in identity management strategies as an effective way to reduce workplace discrimination, particularly subtle forms of discrimination. The aim of the current study is to examine the use and effectiveness of different methods of the specific identity management strategy of acknowledging race as a way to reduce workplace discrimination and lead to other positive outcomes for Black individuals. A sample of Black and White individuals with professional work experience participated in an online vignettebased survey. Participants read four short vignettes involving race in the workplace and responded to a series of questions assessing usage of various acknowledgment strategies, affective outcomes, and perceptions of effectiveness. Results revealed that Black individuals reported acknowledging their race to a greater extent than did White individuals, and Black people reported positive benefits of affirming race and using humor to discuss their race. Finally, Black participants found racial acknowledgments to be more effective than White participants. Implications and future directions are discussed

Glucoregulatory Consequences and Cardiorespiratory Parameters in Rats Exposed to Chronic–Intermittent Hypoxia: Effects of the Duration of Exposure and Losartan

Background: Obstructive sleep apnea (OSA) is associated with glucose intolerance. Both chronic sleep disruption and recurrent blood oxygen desaturations (chronic–intermittent hypoxia, CIH) may cause, or exacerbate, metabolic derangements. Methods: To assess the impact of CIH alone, without accompanying upper airway obstructions, on the counter-regulatory response to glucose load and cardiorespiratory parameters, we exposed adult male Sprague-Dawley rats to CIH or sham room air exchanges for 10 h/day for 7, 21, or 35 days and then, 1 day after conclusion of CIH exposure, conducted intravenous glucose-tolerance tests (ivgtt) under urethane anesthesia. Additional rats underwent 35 days of CIH followed by 35 days of regular housing, or had 35 day-long CIH exposure combined with daily administration of the type 1 angiotensin II receptor antagonist, losartan (15 mg/kg, p.o.), and then were also subjected to ivgtt. Results: Compared with the corresponding control groups, CIH rats had progressively reduced glucose-stimulated insulin release and impaired glucose clearance, only mildly elevated heart rate and/or arterial blood pressure and slightly reduced respiratory rate. The differences in insulin release between the CIH and sham-treated rats disappeared in the rats normally housed for 35 days after 35 days of CIH/sham exposure. The losartan-treated rats had improved insulin sensitivity, with no evidence of suppressed insulin release in the CIH group. Conclusion: In adult rats, the glucose-stimulated insulin release is gradually suppressed with the duration of exposure to CIH, but the effect is reversible. Elimination of the detrimental effect of CIH on insulin release by losartan suggests that CIH disrupts glucoregulation through angiotensin/catecholaminergic pathways. Accordingly, treatment with continuous positive airway pressure may ameliorate pre-diabetic conditions in OSA patients, in part, by reducing sympathoexcitatory effects of recurrent nocturnal hypoxia
