Heterosexual Casual Sex and STI Diagnosis: A Latent Class Analysis

Casual sex is common during the emerging adult life course stage, but little research has taken a person-centered approach to investigate if casual sexual behavior influences sexually transmitted infection (STI) rates. Using a nationally representative sample and latent class analysis, results showed three distinctive latent classes. Abstainers were the least likely to have an STI, followed by the casual sex experienced, and then the casual sex risk-takers. Once other covariates were included in the model, there was no significant difference between the abstainers and casual sex experienced classes. These results highlight the need for future research to include diverse samples of emerging adults.     

Reliability and validity of the Vulnerability Index-Service Prioritization Decision Assistance Tool (VI-SPDAT) in real-world implementation

This study examined the reliability and validity of the Vulnerability Index-Service Prioritization Decision Assistance Tool (VI-SPDAT), a widely-used assessment of the health and social vulnerabilities and housing needs of individuals experiencing homelessness. Homeless Management Information System data were obtained for 1495 individuals who were administered the VI-SPDAT between 2014 and 2016. Subsamples were selected for reliability and validity assessments. Results suggest there are challenges to the reliability and validity of the VI-SPDAT in practical use. VI-SPDAT total scores did not significantly predict risk of return to homeless services, while type of housing was a significant predictor. Vulnerability assessment instruments have important implications for communities working to end homelessness by facilitating prioritization of scarce housing resources. Findings suggest that further testing and development of the VI-SPDAT is necessary.     

Motives for sharing illness experiences on Twitter: conversations of parents with children diagnosed with cancer

A patient- and family-centred approach in paediatric health care is important because parents are involved in making key decisions about their child’s health care and advocating for the best interest of the child. Parents and family members are increasingly turning to the internet to find and actively share information about their child’s health care. Twitter is one of many online platforms used by parents of children diagnosed with cancer to share information related to their child’s cancer experience. Existing research suggests that there is a need to better understand the motives for using Twitter for sharing content about a child’s cancer experience. Furthermore, there is a lack of theoretical frameworks for characterizing those motives. In this paper, we identify key themes of tweets posted by parents of children diagnosed with cancer and align those themes with motives inspired by the well-studied Everyday Life Information Seeking framework. We propose a new motive in addition to those associated with the framework and suggest that information can be shared for endogenous reasons as well as to meet the needs of others. This paper contributes an increased understanding of motives for sharing information about a child’s cancer journey and extends a theoretical framework for building further knowledge in this area.     

Complexity analysis of the Next Gen Air Traffic Management System: trajectory based operations

According to Federal Aviation Administration traffic predictions currently our Air Traffic Management (ATM) system is operating at 150 percent capacity; forecasting that within the next two decades, the traffic with increase to a staggering 250 percent [17]. This will require a major redesign of our system. Today's ATM system is complex. It is designed to safely, economically, and efficiently provide air traffic services through the cost-effective provision of facilities and seamless services in collaboration with multiple agents however, contrary the vision, the system is loosely integrated and is suffering tremendously from antiquated equipment and saturated airways. The new Next Generation (Next Gen) ATM system is designed to transform the current system into an agile, robust and responsive set of operations that are designed to safely manage the growing needs of the projected increasingly complex, diverse set of air transportation system users and massive projected worldwide traffic rates. This new revolutionary technology-centric system is dynamically complex and is much more sophisticated than it's soon to be predecessor. ATM system failures could yield large scale catastrophic consequences as it is a safety critical system. This work will attempt to describe complexity and the complex nature of the NextGen ATM system and Trajectory Based Operational. Complex human factors interactions within Next Gen will be analyzed using a proposed dual experimental approach designed to identify hazards, gaps and elicit emergent hazards that would not be visible if conducted in isolation. Suggestions will be made along with a proposal for future human factors research in the TBO safety critical Next Gen environment.     

Māori and Pasifika leaders’ experiences of government health advisory groups in New Zealand

Māori and Pasifika populations in New Zealand experience poorer health outcomes than other New Zealanders. These inequalities are a deeply entrenched injustice. This qualitative study explores the experiences of six Māori and Pasifika leaders on health policy-making advisory committees. All had extensive experience in the health system. They were recruited, provided semi-structured interviews, the data coded, and a thematic analysis undertaken. Our findings show that inequalities in the health system are reproduced in advisory committees. Participants noted their knowledge and interests were devalued and they experienced racism and tokenistic engagement. Some indicated it took considerable effort to establish credibility, be heard, have impact, and navigate advisory meetings, but even then their inputs were marginalised. Health policy advisory committees need deeper engagement and more genuine recognition of Māori and Pasifika knowledge. Māori and Pasifika leaders have constructive solutions for eliminating health inequities that could benefit all New Zealanders.
