    International Space Station Alpha (ISSA) will accommodate a variety of user payloads investigating diverse scientific and technology disciplines on behalf of five international partners: Canada, Europe, Japan, Russia, and the United States. A combination of crew, automated systems, and ground operations teams will control payload operations that require complementary on-board and ground systems. This paper presents the current planning for the ISSA U.S. user payload operations concept and the functional architecture supporting the concept. It describes various NASA payload operations facilities, their interfaces, user facility flight support, the payload planning system, the onboard and ground data management system, and payload operations crew and ground personnel training. This paper summarizes the payload operations infrastructure and architecture developed at the Marshall Space Flight Center (MSFC) to prepare and conduct ISSA on-orbit payload operations from the Payload Operations Integration Center (POIC), and from various user operations locations. The authors pay particular attention to user data management, which includes interfaces with both the onboard data management system and the ground data system. Discussion covers the functional disciplines that define and support POIC payload operations: Planning, Operations Control, Data Management, and Training. The paper describes potential interfaces between users and the POIC disciplines, from the U.S. user perspective

    The Antihero in Popular Culture: A Life History Theory of the Dark Triad

    Get PDF
    The Dark Triad of personality is composed of narcissism, psychopathy, and Machiavellianism. Despite the common belief that these traits are undesirable, the media is awash with characters that embody the Dark Triad. Characters like Gregory House, M.D., Batman (a.k.a. the Dark Knight), and James Bond all embody these traits and are some of the most popular media franchises today. As entertaining as these characters are, they provide us with a window into the dark side of human nature. Instead of treating the dark side of human nature as inherently maladaptive, we provide an alternative view that, despite their costs, traits like these can confer reproductive and survival benefits for the individual. In so doing, we review the research on the Dark Triad traits and provide a theoretical account for how these traits can confer some positive benefits. To facilitate comprehension, we provide examples taken from the media to show how evolutionary psychology and popular culture intersect

    Childhood emotional trauma and cyberbullying perpetration among emerging adults: a multiple mediation model of the role of problematic social media use and psychopathology

    Research suggests that a small minority of social media users experience problems as a result of their online use. The purpose of the present study was to examine the association of cyberbullying perpetration and problematic social media use with childhood emotional trauma, Cluster B (narcissistic, histrionic, antisocial, and borderline) personality traits, dissociative experiences (DEs), depression, and self-esteem in a nonclinical undergraduate sample. A total of 344 university students volunteered to complete a questionnaire that included measures on the aforementioned dimensions. Thirty-eight percent of the participants had emotional neglect and 27% had emotional abuse, while 44% of them demonstrated at least one cyberbullying perpetration behavior. Results indicated that cyberbullying perpetrators had higher scores on problematic social media use, dissociative experiences, Cluster B traits, depression and childhood emotional trauma, and lower on self-esteem. Path analysis demonstrated that, while adjusting for gender and age, childhood emotional trauma was directly and indirectly associated with cyberbullying perpetration via Cluster B traits. Moreover, depression and dissociation were directly associated with problematic social media use. The findings of this study emphasize the important direct role of childhood emotional trauma and pathological personality traits on cyberbullying perpetration

    Personality, dangerous driving, and involvement in accidents: Testing a contextual mediated model

    The present study tested the role of various personality traits in explaining dangerous driving and involvement in accidents, using a contextual mediated model (N = 311). We initially found direct effects of personality traits on dangerous driving indicators (Big-5, Dark Triad, sensation seeking, aggression, and impulsivity). Subsequently, personality variables with predictive power were tested in the mediation model. Indirect effects of anger, psychopathy and sensation seeking on the history of involvement in traffic accidents were found, which was predicted directly by risky driving. The results are discussed based on the characteristics of each trait. Overall, our research replicates and extends previous findings and highlights the importance of psychological evaluations (e.g., personality test) when prospective drivers are applying for a driver license

    Schadenfreude and the spread of political misfortune.

    Schadenfreude is a social emotion that describes one's happiness at the misfortune of others. Because people experience schadenfreude to different extents, it can also be considered a trait. The present research aimed to develop a trait measure of schadenfreude and investigate the relationship between schadenfreude and political downfalls. We developed an item pool and used exploratory (Study 1) and confirmatory (Study 2) factor analyses to establish a 12-item, two-factor schadenfreude measure: benign and malicious. We also assessed its test-retest reliability (Study 3) and convergent validity with related measures (Study 4). Findings supported a two-factor schadenfreude measure that produced valid and reliable scores (Studies 1-4). In an experiment, we found a positive correlation between episodic-but not trait-schadenfreude on spreading news of a politician's downfall (Study 5). Using a 3 (Political affiliation: Democrat, Republican, or other) × 3 (Manipulated condition: Democrat, Republican, or CEO) design, we examined the extent to which participants' schadenfreude predicted their intentions and choices to share an embarrassing news story about a politician or CEO via social media. Schadenfreude can be assessed as a reliable trait-one that may help us predict why some people intend to spread news of embarrassing political failures

    Mutually attracted or repulsed? : actor-partner interdependence models of Dark Triad traits and relationship outcomes

    Although the Dark Triad traits - narcissism, Machiavellianism, and psychopathy - have been studied in individuals, little is known about their roles in dating relationships. Forty-five heterosexual undergraduate couples (N= 90) reported measures of the Dark Triad and relationship commitment and satisfaction. Within couples, assortative mating was slightly negative for narcissism, marginally positive for Machiavellianism, and significantly positive for psychopathy. Using actor-partner interdependence models, we explored the extent to which satisfaction mediated the direct associations between the Dark Triad and commitment. Men's satisfaction marginally mediated the women's Dark Triad. →. men's commitment negative association. Among the three Dark Triad subscales, satisfaction marginally mediated both of the actor-effect-based psychopathy. →. commitment negative associations. We discuss possible implications for couples' relationship strategies

    Prior storm experience moderates water surge perception and risk

    Background How accurately do people perceive extreme water speeds and how does their perception affect perceived risk? Prior research has focused on the characteristics of moving water that can reduce human stability or balance. The current research presents the first experiment on people's perceptions of risk and moving water at different speeds and depths. Methods Using a randomized within-person 2 (water depth: 0.45, 0.90 m) ×3 (water speed: 0.4, 0.8, 1.2 m/s) experiment, we immersed 76 people in moving water and asked them to estimate water speed and the risk they felt. Results Multilevel modeling showed that people increasingly overestimated water speeds as actual water speeds increased or as water depth increased. Water speed perceptions mediated the direct positive relationship between actual water speeds and perceptions of risk; the faster the moving water, the greater the perceived risk. Participants' prior experience with rip currents and tropical cyclones moderated the strength of the actual–perceived water speed relationship; consequently, mediation was stronger for people who had experienced no rip currents or fewer storms. Conclusions These findings provide a clearer understanding of water speed and risk perception, which may help communicate the risks associated with anticipated floods and tropical cyclones

    An actor-partner interdependence model of the Dark Triad and aggression in couples : relationship duration moderates the link between psychopathy and argumentativeness

    Prior research has examined links between Dark Triad traits-Machiavellianism, psychopathy, and narcissism-and aggression in individuals, but not couples. Dating heterosexual couples self-reported measures of the Dark Triad and aggression (trait and displaced; Study 1) or negativity (Study 2). Actor-partner interdependence models showed positive links between (a) women's psychopathy and women's trait and displaced aggression (actor effects), and (b) men's psychopathy and women's trait aggression (partner effect). Positive actor effects also linked narcissism to displaced aggression. Using integrative data analysis to combine Studies 1 and 2, relationship duration moderated actor and partner effects linking psychopathy to women's argumentativeness (negativity and verbal aggression); men in longer relationships and women in shorter relationships had psychopathy-argumentativeness slopes that were especially positive
