    In recognition of increasing rates of repeated ground schools and flight lessons, in combination with decreasing retention rates in the flight programs at Embry-Riddle Aeronautical University, the Department of Aeronautical Science in the College of Aviation took initiative to create a program that identified struggling students before they reached excessive failure or financial distress. The students identified in the Student Success Initiative (SSI) after being assessed would be required to attend a mediation session with their academic and flight training staff in order to create a specialized training program

    A pair of Jovian Trojans at the L4 Lagrange point

    Asteroid pairs, two objects that are not gravitationally bound to one another, but share a common origin, have been discovered in the Main belt and Hungaria populations. Such pairs are of major interest, as the study of their evolution under a variety of dynamical influences can indicate the time since the pair was created. To date, no asteroid pairs have been found in the Jovian Trojans, despite the presence of several binaries and collisional families in the population. The search for pairs in the Jovian Trojan population is of particular interest, given the importance of the Trojans as tracers of planetary migration during the Solar system's youth. Here we report a discovery of the first pair, (258656) 2002~ES76_{76} and 2013~CC41_{41}, in the Jovian Trojans. The two objects are approximately the same size and are located very close to the L4 Lagrange point. Using numerical integrations, we find that the pair is at least 360360~Myr old, though its age could be as high as several Gyrs. The existence of the (258656) 2002~ES76_{76}--2013~CC41_{41} pair implies there could be many such pairs scattered through the Trojan population. Our preferred formation mechanism for the newly discovered pair is through the dissociation of an ancient binary system, triggered by a sub-catastrophic impact, but we can not rule out rotation fission of a single object driven by YORP torques. A by-product of our work is an up-to-date catalog of Jovian Trojan proper elements, which we have made available for further studies.Comment: 15 figs. Accepted for publication in MNRA

AQR provides consumers and industry watchers a means to compare performance quality among different US airlines using objective performance-based data. This research looks to analyze the cyclical patterns present in AQR in order to identify trends and factors contributing to the changes in these results each year. This research utilizes the application of a longitudinal analysis methodology which will provide the correlation between factors identified and the indicators affected

    Assessing HIV risk and the social and behavioural characteristics of gay and bisexual men who have recently migrated to Australia: an analysis of national, behavioural surveillance data 2019–2021

    Full text link
    Introduction: Overseas‐born gay and bisexual men (GBM) are overrepresented in HIV diagnoses in Australia. We assessed social and sexual behaviours, and the use of HIV prevention and testing, by region of birth and length of residence in Australia. We sought to identify similarities and differences between recently arrived and non‐recently arrived GBM from non‐English‐speaking countries to improve targeting and engagement with HIV testing and prevention. Methods: Data were collected in national repeated, behavioural surveillance surveys conducted across Australia during 2019–2021. Logistic regression was used to identify factors that differentiated between recently arrived (<2 years) and non‐recently arrived (≥2 years in Australia) GBM from non‐English‐speaking countries. Results Among 24,707 participants in 2019–21, 2811 (11.4%) were from high‐income English‐speaking countries, 714 (2.9%) were recently arrived overseas‐born GBM and 3833 (15.5%) were non‐recently arrived migrants. Recently arrived GBM were most likely to be born in Asia (36.1%) and Europe (21.1%). Compared with non‐recently arrived GBM, recently arrived GBM from non‐English‐speaking countries were younger (aOR = 0.95, 95% CI = 0.94–0.96, p<0.001), more likely to be students (aOR = 1.43, 95% CI = 1.11–1.85, p=0.005), less likely to be in full‐time employment (aOR = 0.56, 95% CI = 0.46–0.69, p<0.001), more likely to report consistent condom use (aOR = 1.30, 95% CI = 1.01–1.66, p=0.039), but had lower awareness (aOR = 0.62, 95% CI = 0.48–0.80, p<0.001) and use of pre‐exposure prophylaxis (PrEP) (22.8%, vs. 32.3%, χ2(1, 4185) = 23.78, p<0.001), and similar levels of casual sex with a risk of HIV acquisition or transmission (aOR = 1.29, 95% CI = 0.98–1.69, p=0.066). Recently arrived GBM reported similar levels of lifetime HIV testing (aOR = 0.97, 95% CI = 0.54–1.74, p=0.915) and recent HIV testing (OR = 1.03, 95% CI = 0.86–1.22, p=0.779), but were much less likely to have tested at general practitioners (aOR = 0.53, 95% CI = 0.41–0.68, p<0.001) and more likely to report testing at hospitals (aOR = 3.35, 95% CI = 2.53–4.43, p<0.001), at home (aOR = 2.85, 95% CI = 1.63–4.99, p<0.001), or community‐based services (aOR = 1.36, 95% CI = 1.01–1.84, p=0.043). Conclusions: Recently arrived GBM from non‐English‐speaking countries reported similar levels of risk of HIV acquisition to longer‐term residents in Australia, but lower levels of PrEP awareness and use, and more reliance on HIV testing services which are free or low cost. It is necessary to enhance access to HIV testing and prevention among recently arrived GBM in Australia

    Variations in HIV Prevention Coverage in Subpopulations of Australian Gay and Bisexual Men, 2017–2021: Implications for Reducing Inequities in the Combination Prevention Era

    Full text link
    Using repeated behavioural surveillance data collected from gay and bisexual men (GBM) across Australia, we assessed trends in HIV prevention coverage (the level of ‘safe sex’ achieved in the population by the use of effective prevention methods, including condoms, pre-exposure prophylaxis [PrEP] and having an undetectable viral load). We stratified these trends by age, country of birth/recency of arrival, sexual identity, and the proportion of gay residents in the participant’s suburb. Among 25,865 participants with casual male partners, HIV prevention coverage increased from 69.8% in 2017 to 75.2% in 2021, lower than the UNAIDS target of 95%. Higher levels of coverage were achieved among older GBM (≥ 45 years), non-recently-arrived migrants, and in suburbs with ≥ 10% gay residents. The lowest levels of prevention coverage (and highest levels of HIV risk) were recorded among younger GBM (&lt; 25 years) and bisexual and other-identified participants. Younger, recently-arrived, and bisexual GBM were the most likely to use condoms, while PrEP use was concentrated among gay men, 25–44-year-olds, and in suburbs with more gay residents. The use of undetectable viral load was most common among participants aged ≥ 45 years. Our analysis shows that high HIV prevention coverage can be achieved through a mixture of condom use, PrEP use, and undetectable viral load, or by emphasising PrEP use. In the Australian context, younger, bisexual and other-identified GBM should be prioritised for enhanced access to effective HIV prevention methods. We encourage other jurisdictions to assess the level of coverage achieved by combination prevention, and variations in uptake

    Trends in illicit drug use and their association with HIV transmission risks from behavioural surveillance of Australian gay and bisexual men

    Full text link
    Introduction. Investigating drug trends among Australian gay and bisexual men (GBM) is crucial for understanding levels of use and the potential for harm, including HIV transmission risk. Method. Using repeated, national, cross‐sectional survey data collected between 2012 and 2021 (69,567 surveys), trends of recent (previous 6 months) and frequent (weekly) drug use were analysed, using logistic regression models. The last round of data from each jurisdiction (6709 surveys) was used to compare GBM who reported no use, infrequent (less than weekly) use and frequent (at least weekly) use of party drugs to investigate the association between party drug use and HIV transmission risk, using multinomial logistic regression models. Results. There was a significant upward trend in any recent drug use (from 58.4% in 2012 to 64.1% in 2021; p<0.001). Frequent party drug use remained a minority practice over the period (consistently less than 3%). In cross‐sectional analysis, frequent party drug users were more likely to report behaviours with HIV transmission risks, such as condomless anal intercourse without biomedical prevention strategies (30.0% vs. 13.1%; adjusted relative risk ratio [aRRR], 2.08; 95% CI, 1.24–3.47), weekly group sex (16.3% vs. 0.6%; aRRR, 12.36; 95% CI, 5.75–26.56) and more than 20 recent sexual partners (42.5% vs. 5.0%; aRRR, 21.44; 95% CI, 5.82–78.89), compared with GBM who did not use party drugs. Discussion and Conclusion. Our findings suggest that the frequent use of party drugs remains a marker of HIV transmission risk among Australian GBM, despite the increased adoption of biomedical HIV prevention strategies over the past few years

    Quality, Performance, and Consumer Perceptions: A National Study of US Airlines

    Prior inquiry into consumer perceptions, attitudes, and overall satisfaction regarding commercial mainline passenger carriers in the United States has provided little more than a snapshot of the average air traveler. Building on 28 continuous years of research with the National Airline Quality Rating (AQR), this study attempts to move beyond descriptive information in order to identify relationships and trends in the airline industry’s performance and relate those observations to consumer perceptions. This study will utilize a comparative trend analysis methodology to analyze major United States Airlines\u27 performance and quality over the last 28 years. This methodology provides a means of tracking airline\u27s progressions and regressions in operational performance and allows for the development of theories in data shifts and trends. This study will attempt to exemplify the objective formula-driven weighted averages that constitute the Airline Quality Rating. The development of this qualitative model provides industry leaders with the ability to improve their understanding of airline performance and make adjustments to their operations for continued growth development.

    Background. Asian gay, bisexual, and other men who have sex with men (GBMSM) are overrepresented in new HIV diagnoses in Australia. Social engagement with other GBMSM has been associated with HIV testing and pre-exposure prophylaxis (PrEP) uptake. Asian GBMSM may be socially disconnected from LGBTQ+ people, which may increase their HIV risk. This analysis assessed the contribution of social connection on HIV risk among Asian GBMSM. Methods. Using an online cross-sectional survey of Asian GBMSM in Australia, we measured condomless anal intercourse (CLAI) in the last 6 months without PrEP or an undetectable viral load (UVL), i.e. CLAI with a risk of HIV transmission. Bivariable and multivariable logistic regression models were performed to compare demographic characteristics and social engagement of participants who had CLAI without PrEP or UVL to those who had not. Analyses were restricted to participants who reported sex with casual partners in the last 6 months. Results. Among 509 participants who had casual partners in the last 6 months, 151 (29.7%) reported CLAI without PrEP or UVL. CLAI without PrEP or UVL was negatively associated with full-time employment, and recently being tested for HIV and was positively associated with experiencing discrimination based on sexual orientation. Social engagement with LGBTQ+ people was not associated with CLAI without PrEP or UVL. Conclusions. CLAI without PrEP or UVL was not related to social connections with LGBTQ+ people but was more likely among Asian men who had experienced sexuality-related discrimination, suggesting that mitigating homophobia and biphobia may assist in improving HIV prevention among Asian GBMSM who live in Australia

    Adjusting Behavioural Surveillance and Assessing Disparities in the Impact of COVID-19 on Gay and Bisexual Men’s HIV-Related Behaviour in Australia

    Full text link
    COVID-19 has disrupted sexual behaviour and access to health systems. We adapted regular HIV behavioural surveillance of gay and bisexual men (GBM) in Australia in response to COVID-19, assessed the impact on the profile of the sample, the participants’ HIV-related behaviour, and whether COVID-19 may have accentuated existing disparities in the Australian HIV epidemic. Data collected from five states during July 2017–June 2021 were included (N = 31,460). The emphasis on online recruitment after COVID-19 led to smaller sample sizes, greater geographic reach, and a higher proportion of bisexual-identifying participants. Most participants (88.1%) reported physical distancing and 52.1% had fewer sex partners due to COVID-19. In the COVID-19-affected rounds (July 2020–June 2021), the number of male partners, recent HIV testing and pre-exposure prophylaxis (PrEP) use all fell, and HIV risk among the smaller group of participants who reported casual sex increased. COVID-related changes were generally more pronounced among GBM aged under 25 years, participants from suburbs with fewer gay residents, and bisexual men. These groups should be prioritised when encouraging GBM to reengage with HIV testing services and effective prevention methods, like condoms and PrEP
