The Effects of Automation Expertise, System Confidence, and Image Quality on Trust, Compliance, and Performance

This study examined the effects of automation expertise, system confidence, and image quality on automation trust, compliance, and detection performance. One hundred and fifteen participants completed a simulated military target detection task while receiving advice from an imperfect diagnostic aid that varied in expertise (expert vs. novice) and confidence (75% vs. 50% vs. 25% vs. no aid). The task required participants to detect covert enemy targets in simulated synthetic aperture radar (SAR) images. Participants reported whether a target was present or absent, their decision-confidence, and their trust in the diagnostic system\u27s advice. Results indicated that system confidence and automation expertise influenced automation trust, compliance, and measures of detection performance, particularly when image quality was poor. Results also highlighted several incurred costs of system confidence and automation expertise. Participants were more apt to generate false alarms as system confidence increased and when receiving diagnostic advice from the expert system. Data also suggest participants adopted an analogical trust tuning strategy rather than an analytical strategy when evaluating system confidence ratings. This resulted in inappropriate trust when system confidence was low. Theoretical and practical implications regarding the effects of system confidence and automation expertise on automation trust and the design of diagnostic automation are discussed

Beyond the Bright Side: Dark Personality at Work

Despite the long history of the psychological study of dark personality characteristics and the recent surge of interest in the topic, much work remains to fully understand the breadth and depth of the impact of dark personality in the workplace. This commentary briefly covers the history of dark personality, discusses the place of this special issue within that history, and then proposes a number of avenues for future research in terms of defining, measuring, and providing a more comprehensive theoretical framework for the study of dark personality

Follower Perceptions Deserve a Closer Look

On the whole, we embrace the wisdom of Lord and Dinh’s suggestion that leadership researchers need to refocus our attention on the distinction between leadership perception and effectiveness. That said, we hope that the field can move one step further by recognizing the need to treat perceptual biases as more than systematic errors to be controlled for. As encoded in Lord and Dinh’s first two principles, followers are active participants in the construction of leadership phenomena, so the perceptual “baggage” that they bring into the leader–follower system is an important building block in that construction. We believe that by accounting for perceiver effects in leadership research we can not only help disentangle leadership perception from effectiveness but also open up new opportunities to explore how perceptions may drive effectiveness. In addition, we believe that a better understanding of follower perceptions can facilitate more effective management by allowing practicing managers to make sense of the idiosyncratic reactions followers may display in response to the decisions and behaviors of their leaders

Siblings of individuals with severe mental illness

Purpose – The importance of providing information, support and interventions for family members and carers of people who have severe mental illness (SMI) has garnered increasing attention in recent years. However, research to date has primarily focused on parents; the purpose of this paper is to review the literature investigating the experiences of siblings of individuals who have SMI. Design/methodology/approach – A literature review was undertaken to summarise the empirical data regarding the experiences and needs of siblings, and their potential contribution to supporting their siblings’ recovery journey. Findings – Sibling views, experiences and needs have thus far been little explored. Yet siblings often make significant contributions to their brother’s/sister’s care and social and emotional well-being, and their support can positively shape the recovery trajectory. This review finds that siblings require information and support for two reasons: to maintain their own well-being, and to be able to best support their sibling with SMI and the family as a whole. Several implications for clinical practice, workforce development and research are outlined. Originality/value – This paper provides a timely review of the literature to enhance awareness of the needs and experiences of siblings for health and social care professionals. Examples of good practice are proposed for statutory and voluntary service settings

The application of active controls technology to a generic hypersonic aircraft configuration

Analytical methods are described for the prediction of aerothermoelastic stability of hypersonic aircraft including active control systems. Thermal loads due to aerodynamic heating were applied to the finite element model of the aircraft structure and the thermal effects on flutter were determined. An iterative static aeroelastic trim analysis procedure was developed including thermal effects. And active control technology was assessed for flutter suppression, ride quality improvement, and gust load alleviation to overcome any potential adverse aeroelastic stability or response problems due to aerodynamic heating. A generic hypersonic aircraft configuration was selected which incorporates wing flaps, ailerons, and all moveable fins to be used for active control purposes. The active control system would use onboard sensors in a feedback loop through the aircraft flight control computers to move the surfaces for improved structural dynamic response as the aircraft encounters atmospheric turbulence

Cognitive behaviour therapy for social anxiety in autism spectrum disorder: A systematic review.

Purpose Individuals who have autism spectrum disorders (ASD) commonly experience anxiety about social interaction and social situations. Cognitive behaviour therapy (CBT) is a recommended treatment for social anxiety (SA) in the non-ASD population. Therapy typically comprises cognitive interventions, imagery-based work and for some individuals, behavioural interventions. Whether these are useful for the ASD population is unclear. Therefore, the purpose of this paper is to undertake a systematic review to summarise research about CBT for SA in ASD. Design/methodology/approach Using a priori criteria, the authors searched for English-language peer-reviewed empirical studies in five databases. The search yielded 1,364 results. Titles, abstracts, and relevant publications were independently screened by two reviewers. Findings Four single case studies met the review inclusion criteria; data were synthesised narratively. Participants (three adults and one child) were diagnosed with ASD and SA. There were commonalities in interventions and techniques used: participants were encouraged to identify and challenge negative thoughts, enter anxiety-provoking social situations, and develop new ways of coping. Unlike CBT for SA in non-ASD individuals, treatment also included social skills interventions. Outcomes were assessed using self- or informant-reports. Improvements in SA, depressive symptoms, social skills, and activity levels were noted. Generalisability of results is hampered, however, by the small number of studies and participants and lack of randomised controlled trial conditions employed. Research limitations/implications Future studies should investigate how beliefs and behaviours indicative of SA can be ameliorated in individuals with ASD. Originality/value This is the first review to synthesise empirical data about CBT for SA in ASD

Atmospheric bromoform at Mace Head, Ireland: Evidence for a peatland source

International audienceIn situ atmospheric observations of bromoform (CHBr3) made over a 2.5 year period at Mace Head, Ireland from May 2001?December 2003, including during the NAMBLEX (North Atlantic Marine Boundary Layer Experiment) campaign, show broad maxima from spring until autumn and winter minima, with mixing ratios of 5.3+1.0 pptv (mid March?mid October) and 1.8+0.8 pptv (December?February). This indicates that, unlike CHCl3, which has a summer minimum and winter maximum at Mace Head, local biological sources of CHBr3 have a greater influence on the atmospheric data than photochemical decay during long-range transport. The emission sources are predominantly macroalgal, but we find evidence for a small terrestrial flux from peatland ecosystems, which so far has not been accounted for in the CHBr3 budget. Sharp increases in CHCl3 and CHBr3 concentrations and decreases in O3 concentrations occurred at night when the wind direction switched from an ocean- to a land-based sector (land breeze) and the wind speed dropped to below 5 ms?1. These observations infer a shallow atmospheric boundary layer with increased O3 deposition and concentration of local emissions of both CHCl3 and CHBr3. The ratio of ?CHCl3/?CHBr3 varied strongly according to the prevailing wind direction; from 0.6+0.1 in south-easterly (100?170°) air to 1.9+0.8 in north-easterly (40?70°) air. Of these land-sectors, the south-easterly air masses are likely to be strongly influenced by macroalgal beds along the coast and the emission ratios probably reflect those from seaweeds in addition to land sources. The north-easterly airmasses however have a fetch predominantly over land, which locally is comprised of coastal peatland ecosystems (peat bogs and coastal conifer plantations), previously identified as being strong sources of atmospheric CHCl3 under these conditions. Although we cannot entirely rule out other local land or coastal sources, our observations also suggest peatland ecosystem emissions of CHBr3. We use correlations between CHCl3 and CHBr3 during the land breeze events in conjunction with previous estimates of local wetland CHCl3 release to tentatively deduce a global wetland CHBr3 source of 26.9 (0.5?1247) Gg yr?1, which is approximately 10% of the total global source
