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.     

Teaching intercultural awareness to first‐year medical students via experiential exercises

This study assessed the extent to which a one‐time experiential intervention improved intercultural awareness and sensitivity among first‐year medical students. The students participated in group activities in which they shared personal experiences, solved a hypothetical problem, and engaged in team building exercises. Post‐intervention, students reported less intercultural awareness, but a greater commitment to improving the intercultural climate of the medical school and an increased willingness to work in diverse groups during their medical training. The results of the study suggest that experiential interventions may provide an important complement to didactics around issues of intercultural awareness and sensitivity with medical students. Importantly, experiential interventions must provide students with sufficient time to reflect upon and discuss feelings, thoughts and attitudes that emerge during this kind of intercultural awareness training.     

Gender,social change,and the professions: The case of pharmacy

This paper examines the nature of increasing female entry into the profession of pharmacy. Using data from a survey of Ontario pharmacists, it compares the work experiences and career paths of 668 men and women in the profession. In terms of hours worked, where they work, and the nature of the work that they do, we found considerable differences between males and females that are becoming increasingly pronounced as more women enter the profession. These findings are then discussed in terms of available theories of gender, professions and social change.     

Psychological Wellbeing Among Same‐sex Attracted and Heterosexual Parents: Role of Connectedness to Family and Friendship Networks

Increasing numbers of lesbian, gay and bisexual (LGB) adults are entering into parenthood. Previous studies indicate many of these parents receive little or no support from their families of origin due to family members' negative attitudes toward homosexuality. This study looks at the extent to which LGB parents report a lower sense of connectedness to family of origin and friendship networks than heterosexual parents and whether this has an impact on psychological wellbeing in either of these groups. Data were derived from two studies of parents: Work, Love, Play, a study of Australian and New Zealand LGB parents (n=324); and the Longitudinal Study of Australian Children, a population‐based study of young children and parents (n=6460). Structural equation modelling was used to explore the relationships between: parent sexuality and family/friendship connectedness, family/friendship connectedness and psychological wellbeing, parent sexuality and psychological wellbeing. LGB parents reported feeling less connected to their families of origin but more connected to their friendship groups than heterosexual parents. Counter to previous studies, we found no difference in the psychological wellbeing of LGB parents compared to heterosexual parents when examining the direct effect of sexuality on psychological wellbeing. Clinical implications for counsellors and family therapists are discussed.     

The gift-exchange and reciprocity of women in donor-assisted conception

This paper explores the rhetoric of gift‐exchange as it pertains to the donation of ovarian eggs (oocytes) and participation in surrogate pregnancy arrangements. It does so by drawing on the analysis of interviews with New Zealand women engaged in these practices. Contrary to the view that women's reproductive gift‐giving is intrinsically coercive and exploitative, the narrative accounts of donors involved in this research tend to suggest that women's moral identities as ethical subjects are created in the donative process. Despite this, many anxieties and contradictions involving the exchanges of women involved in donor‐assisted reproduction remain. This paper discusses some of these complexities in light of perceptions and theorisations of the gift relationship.     

How to Inform: Comparing Written and Video Education Interventions to Increase Human Papillomavirus Knowledge and Vaccination Intentions in Young Adults

Abstract

Objective: To compare the efficacy of 2 human papillomavirus (HPV) educational interventions on increasing HPV knowledge and vaccination intentions in college students. Participants: Male (n = 60) and female (n = 140) undergraduates (M _age = 20.4, SD = 2.3) recruited from a university in Montreal, Quebec, Canada, from October 2009 to March 2010. Methods: Using theory-based interventions, participants were randomly assigned to either a written HPV pamphlet, an HPV video, or a control. HPV knowledge and vaccination intentions were assessed pre and postintervention. Results: Low baseline knowledge and intentions were found across groups. Postintervention, participants in the written and video interventions had significantly higher knowledge and intentions than the control. No differences were found between written and video interventions on knowledge or intentions. Conclusion: This study, a first in comparing HPV educational formats, suggests that both written and video interventions are equally effective in educating about HPV and increasing young adults’ vaccination intentions.     

A comparison of some nonparametric tests for the simple tree alternative

This paper develops a new test statistic for testing hypotheses of the form H_O M₀=M₁=…=M_k versus H_a: M₀≦M₁,M₂,…,M_k] where at least one inequality is strict. M₀ is the median of the control population and M₁ is the median of the population receiving trearment i, i=1,2,…,k. The population distributions are assumed to be unknown but to differ only in their location parameters if at all. A simulation study is done comparing the new test statistic with the Chacko and the Kruskal-Wallis when the underlying population distributions are either normal, uniform, exponential, or Cauchy. Sample sizes of five, eight, ten, and twenty were considered. The new test statistic did better than the Chacko and the Kruskal-Wallis when the medians of the populations receiving the treatments were approximately the same     

A Comparison of Trans Women,Trans Men,Genderqueer Individuals,and Cisgender Brothers and Sisters on the Bem Sex-Role Inventory: Ratings by Self and Siblings

A U.S. national sample of 295 transgender adults (trans women, trans men, and genderqueer individuals) and their cisgender siblings completed the Bem Sex-Role Inventory about their siblings as well as themselves, which enabled a comparison between self-perceptions and sibling’s perceptions of personality characteristics. Self-reported personality characteristics scored as feminine of trans women were not statistically different from those of their cisgender sisters, but they were significantly higher than self-reported femininity scores of trans men, genderqueer individuals, and cisgender brothers. Self-reported personality characteristics scored as masculine of trans men did not differ significantly from those of their cisgender brothers, but they were higher than those of trans women. Trans men and cisgender brothers were viewed by their siblings in a more sex-typed way than they rated themselves, whereas trans women and cisgender sisters were rated by their siblings in a less sex-typed way than they viewed themselves.
