Uncertainty-Adjusted Translation for Preference-Sensitive Decision Support.
Authors: Dowie J, Kaltoft MK
Abstract
In Multi-Criteria Decision Analysis-based decision support for person-centred care, the person's quantitative preferences (as criterion weightings) are combined with quantified evidence and expert assessments (as option performance ratings on all criteria) to produce a personalised quantified opinion (as a set of expected value option scores). In our current decision support tools, we use the best available (central point) estimates for option performance ratings. The uncertainty surrounding the performance rating estimates, routinely reported by researchers as interva...

Evaluation of the Military Functional Assessment Program for Return-to-Duty Decision Making: A Longitudinal Study.
Authors: Kelley AM, Showers M
Abstract
Following concussion, return-to-duty decisions are made by medical providers and leaders using informal assessment, review of symptom resolution, and clinical assessments. In an effort to provide military-specific tasks for use in the decision making regarding return-to-duty, a battery developed from the set of basic soldier skills, the Military Functional Assessment Program (MFAP), was evaluated for construct validity using clinical assessment outcomes as well as the relationships between MFAP performance and indicators of long-term performance and satisfaction. A to...

Performance, rating of perceived exertion and physiological responses during a Brazilian jiu-jitsu match: comparisons between winning and losing athletes
AbstractThe purpose of the present study was to describe the physiological, perceptive and performance responses across Brazilian jiu-jitsu (BJJ) match simulation and compare them between winning and losing athletes. Fourteen male adult BJJ athletes (age: 25.8 ± 3.4 years; height: 174.8 ± 9.2 cm; body mass: 79.6 ± 12.4 kg; training experience: 7.0 ± 2.5 years), 6 brown and 8 black belts participated in this study. All athletes performed a combat simulation of 10 min. Heart rate (HR), rating of perceived exertion (RPE) and maximal isometric handgrip strength (MIHS) were evaluated before the combat a...

Outcome Bias in Subjective Ratings of Performance: Evidence from the (Football) Field
Publication date: Available online 12 December 2018Source: Journal of Economic PsychologyAuthor(s): Edgar E. Kausel, Santiago Ventura, Arturo RodríguezAbstractThe outcome bias occurs when people assess others’ decision making process or performance and put an unwarranted weight to their outcomes. This bias has important implications for the judgment and choice as well as the performance appraisal literatures.However, virtually every extant study has been conducted in the lab, likely due to endogeneity concerns in field. Penalty shoot-outs in association football (‘soccer’) offer an interesting way of studying outcom...

Self-Paced Team-Sport Match Simulation Results in Reductions in Voluntary Activation and Modifications to Biological, Perceptual, and Performance Measures at Halftime and for up to 96 Hours Postmatch
Tofari, PJ, Kemp, JG, and Cormack, SJ. Self-paced team-sport match-simulation results in reductions in voluntary activation and modifications to biological, perceptual, and performance measures at halftime and for up to 96 hours postmatch. J Strength Cond Res 32(12): 3561–3572, 2018—Assessing responses to soccer match play is limited by match variability or unrealistic simulations. To address this, the biological, perceptual, and performance responses were assessed using a self-paced, simulated soccer match protocol using a nonmotorized treadmill. Twelve male team-sport athletes performed the 90-minute simulation. Matc...

Chasing the zone: Reduced beta power predicts baseball batting performance
Publication date: Available online 6 September 2018Source: Neuroscience LettersAuthor(s): Anthony Pluta, Chad C. Williams, Gordon Binsted, Kent G. Hecker, Olave E. KrigolsonAbstractMental state prior to sports skill execution is related to subsequent performance. For example, relationships between pre-performance electroencephalogram (EEG) power and subsequent movement outcomes in golf putting, pistol shooting, and basketball free throw shooting have been previously reported. With that said, the existing body of research examining the pre-performance EEG – performance relationship has been focused on the execution of int...

Towards automated assessment of team performance by mimicking expert observers ’ ratings
This study investigates the reliability of human observers as assessors of performance among virtual teams, and what they base their assessments on when only able to monitor one of the team members at a time. The results show that expert observers put a lot of emphasis on task outcomes and on communication and are generally reliable raters of team performance, but there are several aspects that they cannot rate reliably under these circumstances, e.g., team workload, stress, and collaborative problem-solving. Through simple algorithms, this study shows that by capturing task scores and different quantitative communication ...

IJERPH, Vol. 15, Pages 1345: The Importance of External Contacts in Job Performance: A Study in Healthcare Organizations Using Social Network Analysis
David Reeves
There is evidence that relations between physicians and nurses within healthcare institutions might be shaped by informal aspects of such relations and by links to people external to the organization, with an impact on work performance. Social network analysis is underutilized in exploring such associations. The paper aims to describe physicians’ and nurses’ relationships outside their clinical units and to explore what kind of ties are related to job performance. A network analysis was performed on cross-sectional data. The study population consisted of 196 healthcare employees...

IJERPH, Vol. 15, Pages 339: A Comparison of Military and Law Enforcement Body Armour
This study investigated differences between selected military body armour (MBA: 6.4 kg) and law-enforcement body armour (LEBA: 2.1 kg) in impacts on postural sway, vertical jump, agility, a functional movement screen (FMS), task simulations (vehicle exit; victim recovery), and subjective measures. Ten volunteer police officers (six females, four males) were randomly allocated to one of the designs on each of two days. Body armour type did not significantly affect postural sway, vertical jump, vehicle exit and 5 m sprint times, or victim recovery times. Both armour types increased sway velocity and sway-path length in the f...

Dark personality, job performance ratings, and the role of political skill: An indication of why toxic people may get ahead at work
In this study, an indirect effect chain model was tested which proposes that dark employees receive good performance ratings through political skill. Dark personality was operationalized by low scores on the honesty-humility factor of the HEXACO personality model. One hundred and ten employees provided self-ratings on honesty-humility and political skill. Their supervisors provided observer ratings on political skill and job performance. Results show a positive direct effect of honesty-humility on the performance measure of team facilitation and support at the same time the opposing indirect effect hypothesis: Dark, as opp...

What goes up must . . . Keep going up? Cultural differences in cognitive styles influence evaluations of dynamic performance.
Past research on dynamic workplace performance evaluation has taken as axiomatic that temporal performance trends produce naïve extrapolation effects on performance ratings. That is, we naïvely assume that an individual whose performance has trended upward over time will continue to improve, and rate that individual more positively than an individual whose performance has trended downward over time—even if, on average, the 2 individuals have performed at an equivalent level. However, we argue that such naïve extrapolation effects are more pronounced in Western countries than Eastern countries, owing to Eastern countri...

The ability to self ‐monitor cognitive performance during 60 h total sleep deprivation and following 2 nights recovery sleep
Summary
We aimed to investigate whether self‐monitoring of performance is altered during 60 h of total sleep deprivation, following 2 nights of recovery sleep, and by task difficulty and/or subjective sleepiness. Forty adults (22 females, aged 19–39 years) underwent a 5‐day protocol, with a well‐rested day, 66 h total sleep deprivation (last test session at 60 h), and 2 nights of 8 h recovery sleep. An arithmetic task (MATH) with three difficulty levels assessed working memory. The Psychomotor Vigilance Task assessed sustained attention. Arithmetic accuracy and Psychomotor Vigilance Task median reaction time...
