How asynchronous video interviews are used in practice:A study of an Australian‐based AVI vendor

With an archival data set from an Australian-based asynchronous video interview (AVI) vendor, we examined how employers implemented AVI features as a step toward understanding how AVIs can be more optimally designed. The multilevel data contained information about 2,550,105 responses from 627,999 candidates to 52,623 questions, nested within 12,105 interview templates. We found that AVIs were often used for small applicant pools (Mdn = 10 candidates per AVI) and that a majority of the AVIs comprised four to five questions, with candidates typically given 30 seconds to prepare a response, and 2 minutes to record it. Only rarely were candidates permitted to preview questions or re-record responses. Finally, we noted that the settings typically applied were highly consistent with platform's default settings

Competition, autonomy, and prestige: Mechanisms through which the Dark Triad predict job satisfaction

Organizational researchers increasingly recognize the need to consider the Dark Triad traits (i.e., psychopathy, Machiavellianism, and narcissism) when explaining undesirable work outcomes (e.g., counterproductive behaviors). However, little research has focused on the motivations of those who actually hold the traits. In this study (N= 361) we examined how the Dark Triad traits predispose individuals to perceive situations as competitive, prestigious, and comprised of restrictions (i.e., autonomy) which differentially predict job satisfaction. Individuals high on psychopathy and Machiavellianism perceived their workplaces as competitive, whereas individuals high on narcissism perceived their workplaces as prestigious and with fewer restrictions. Sex differences in perceptions were fully mediated by psychopathy and Machiavellianism. We discuss our results from an Evolutionary Industrial/Organization Psychology framework

Thinking Bigger and Better about "Bad Apples": Evolutionary Industrial/Organizational psychology and the Dark Triad

The focal article by Guenole (2014) correctly contends that industrial– organizational (I–O) psychology has been overly reliant on the Big Five or the five-factor model (Benet-Martínez & John, 1998). Although popular and useful, the Big Five also tends to be limited in two important ways. The Big Five is a set of atheoretically derived, descriptive adjectives, and it tends to better tap ‘‘positive’’ aspects of people’s personality over ‘‘negative’’ or ‘‘darker’’ sides. A number of authors have highlighted the importance of examining ‘‘darker’’ aspects of people’s personality both outside (Jonason, Li, Webster, & Schmitt, 2009; Lee & Ashton, 2005; Paulhus & Williams, 2002) and within (Hogan & Hogan, 2001; Jonason, Slomski, & Partyka, 2012) the workplace. As potential mechanisms to explore the ‘‘darker’’ aspects of the workplace, the author of the focal article suggests the Dark Triad of personality (i.e., narcissism, psychopathy, and Machiavellianism). Although the focal article was not solely about these three, we use them as examples to illustrate a broader point: An evolutionary perspective can provide a foundational theory through which workplace phenomenon can be examined with greater richness

Signal detection with criterion noise: Applications to recognition memory

A tacit but fundamental assumption of the theory of signal detection is that criterion placement is a noise-free process. This article challenges that assumption on theoretical and empirical grounds and presents the noisy decision theory of signal detection (ND-TSD). Generalized equations for the isosen-sitivity function and for measures of discrimination incorporating criterion variability are derived, and the model’s relationship with extant models of decision making in discrimination tasks is examined. An experiment evaluating recognition memory for ensembles of word stimuli revealed that criterion noise is not trivial in magnitude and contributes substantially to variance in the slope of the isosensitivity function. The authors discuss how ND-TSD can help explain a number of current and historical puzzles in recognition memory, including the inconsistent relationship between manipulations of learning and the isosensitivity function’s slope, the lack of invariance of the slope with manipulations of bias or payoffs, the effects of aging on the decision-making process in recognition, and the nature of responding in remember–know decision tasks. ND-TSD poses novel, theoretically meaningful constraints on theories of recognition and decision making more generally, and provides a mechanism for rapprochement between theories of decision making that employ deterministic response rules and those that postulate probabilistic response rules

Cultural Differences in Prioritizing Applicant Attributes when Assessing Employment Suitability

We examined how culture influences perceptions of applicant attributes when assessing employment suitability. In two studies (N = 408), we compared members from a collectivistic society (Singapore) to two samples from individualistic societies (the United States and Australia) on their perceptions of applicant attributes across job contexts. For each job, participants either chose between candidates with different attribute profiles or created ideal candidates by allocating a fixed amount of percentile points across different attributes. More often than Australians, Singaporeans chose the candidate with higher levels of the trait (e.g., openness to experience) uniquely associated with the job (e.g., graphic designer). More so than either Americans or Australians, Singaporeans prioritized having the trait most associated with each job. Members from collectivistic societies may require higher levels of the traits most associated with different jobs than members from individualistic societies, who prefer more well-rounded individuals for each job. As discussed, the study of lay perceptions may have implications for training hiring professionals and managers

Occupational Niches and the Dark Triad Traits

Our research focused on the vocational interests correlated with the Dark Triad traits (i.e., narcissism, psychopathy, and Machiavellianism). By understanding how these traits facilitate the structuring of one's environment, we hypothesized that psychopaths will be more interested in realistic and practical careers, narcissists will be more interested in artistic, enterprising, and social careers, and Machiavellians will be more interested in avoiding careers that involve caring for others. In two cross-sectional studies (N= 424; N= 274), we provide general support for these hypotheses. Overall, our study showed those high on the Dark Triad traits may structure their social environment through idealized career preferences. We also show that sex differences in career preferences might be a function, in part of, individual differences in the Dark Triad traits. \ua9 2014 Elsevier Ltd

Human Leukocyte Antigen Profile Predicts Severity of Autoimmune Liver Disease in Children of European Ancestry

Background and Aims Genetic predisposition to autoimmune hepatitis (AIH) in adults is associated with possession of human leukocyte antigen (HLA) class I (A*01, B*08) and class II (DRB1*03, ‐04, ‐07, or ‐13) alleles, depending on geographic region. Juvenile autoimmune liver disease (AILD) comprises AIH‐1, AIH‐2, and autoimmune sclerosing cholangitis (ASC), which are phenotypically different from their adult counterparts. We aimed to define the relationship between HLA profile and disease course, severity, and outcome in juvenile AILD. Approach and Results We studied 236 children of European ancestry (152 female [64%], median age 11.15 years, range 0.8‐17), including 100 with AIH‐1, 59 with AIH‐2, and 77 with ASC. The follow‐up period was from 1977 to June 2019 (median 14.5 years). Class I and II HLA genotyping was performed using PCR/sequence‐specific primers. HLA B*08, ‐DRB1*03, and the A1‐B8‐DR3 haplotype impart predisposition to all three forms of AILD. Homozygosity for DRB1*03 represented the strongest risk factor (8.8). HLA DRB1*04, which independently confers susceptibility to AIH in adults, was infrequent in AIH‐1 and ASC, suggesting protection; and DRB1*15 (DR15) was protective against all forms of AILD. Distinct HLA class II alleles predispose to the different subgroups of juvenile AILD: DRB1*03 to AIH‐1, DRB1*13 to ASC, and DRB1*07 to AIH‐2. Possession of homozygous DRB1*03 or of DRB1*13 is associated with fibrosis at disease onset, and possession of these two genes in addition to DRB1*07 is associated with a more severe disease in all three subgroups. Conclusions Unique HLA profiles are seen in each subgroup of juvenile AILD. HLA genotype might be useful in predicting responsiveness to immunosuppressive treatment and course

Perinatal and 2-year neurodevelopmental outcome in late preterm fetal compromise: the TRUFFLE 2 randomised trial protocol

Introduction: Following the detection of fetal growth restriction, there is no consensus about the criteria that should trigger delivery in the late preterm period. The consequences of inappropriate early or late delivery are potentially important yet practice varies widely around the world, with abnormal findings from fetal heart rate monitoring invariably leading to delivery. Indices derived from fetal cerebral Doppler examination may guide such decisions although there are few studies in this area. We propose a randomised, controlled trial to establish the optimum method of timing delivery between 32 weeks and 36 weeks 6 days of gestation. We hypothesise that delivery on evidence of cerebral blood flow redistribution reduces a composite of perinatal poor outcome, death and short-term hypoxia-related morbidity, with no worsening of neurodevelopmental outcome at 2 years. Methods and analysis: Women with non-anomalous singleton pregnancies 32+0 to 36+6 weeks of gestation in whom the estimated fetal weight or abdominal circumference is <10th percentile or has decreased by 50 percentiles since 18-32 weeks will be included for observational data collection. Participants will be randomised if cerebral blood flow redistribution is identified, based on umbilical to middle cerebral artery pulsatility index ratio values. Computerised cardiotocography (cCTG) must show normal fetal heart rate short term variation (≥4.5 msec) and absence of decelerations at randomisation. Randomisation will be 1:1 to immediate delivery or delayed delivery (based on cCTG abnormalities or other worsening fetal condition). The primary outcome is poor condition at birth and/or fetal or neonatal death and/or major neonatal morbidity, the secondary non-inferiority outcome is 2-year infant general health and neurodevelopmental outcome based on the Parent Report of Children's Abilities-Revised questionnaire.

The development and validation of a scoring tool to predict the operative duration of elective laparoscopic cholecystectomy

Background: The ability to accurately predict operative duration has the potential to optimise theatre efficiency and utilisation, thus reducing costs and increasing staff and patient satisfaction. With laparoscopic cholecystectomy being one of the most commonly performed procedures worldwide, a tool to predict operative duration could be extremely beneficial to healthcare organisations. Methods: Data collected from the CholeS study on patients undergoing cholecystectomy in UK and Irish hospitals between 04/2014 and 05/2014 were used to study operative duration. A multivariable binary logistic regression model was produced in order to identify significant independent predictors of long (> 90 min) operations. The resulting model was converted to a risk score, which was subsequently validated on second cohort of patients using ROC curves. Results: After exclusions, data were available for 7227 patients in the derivation (CholeS) cohort. The median operative duration was 60 min (interquartile range 45–85), with 17.7% of operations lasting longer than 90 min. Ten factors were found to be significant independent predictors of operative durations > 90 min, including ASA, age, previous surgical admissions, BMI, gallbladder wall thickness and CBD diameter. A risk score was then produced from these factors, and applied to a cohort of 2405 patients from a tertiary centre for external validation. This returned an area under the ROC curve of 0.708 (SE = 0.013, p  90 min increasing more than eightfold from 5.1 to 41.8% in the extremes of the score. Conclusion: The scoring tool produced in this study was found to be significantly predictive of long operative durations on validation in an external cohort. As such, the tool may have the potential to enable organisations to better organise theatre lists and deliver greater efficiencies in care
