With the advent of means to generate and disseminate fake, sexualised images of others for the purposes of financial gain, harassment, or sexual gratification, there is a need to assess and understand the public’s awareness and judgements of said behaviour. In two independently-sampled studies, we used moderation (Study 1) and linear mixed effects (Study 2) analyses to investigate whether judgements of deepfaking differed as a function of victim status (celebrity, non-celebrity), victim and participant demographics, and image use (sharing, own sexual gratification), whilst controlling for the potential covariates of psychopathy and beliefs about a just world. We consistently observed more lenient judgements of deepfake generation and dissemination for victims who were celebrities and male, and when images were created for self-sexual gratification rather than being shared. Moreover, lenient judgements, as well as proclivity to act were predicted by greater levels of psychopathy. We discuss our findings in the context of needing to qualitatively understand the general public’s rationale for said disparity in judgements, as well as identifying and combating barriers to disclose victimisation.

Wollack et al. (2015) suggested the erasure detection index (EDI) for detecting fraudulent erasures for individual examinees. Wollack and Eckerly (2017) and Sinharay (2018) extended the index of Wollack et al. (2015) to suggest three EDIs for detecting fraudulent erasures at the aggregate or group level. This article follows up on the research of Wollack and Eckerly (2017) and Sinharay (2018) and suggests a new aggregate-level EDI by incorporating the empirical best linear unbiased predictor from the literature of linear mixed-effects models (e.g., McCulloch et al., 2008). A simulation study shows that the new EDI has larger power than the indices of Wollack and Eckerly (2017) and Sinharay (2018). In addition, the new index has satisfactory Type I error rates. A real data example is also included.

AbstractStudies exploring when social inequalities in body mass index (BMI) and its composites emerge and how these evolve with age are limited. Thus, this study explored parental income and education related inequalities in children’s weight, height, weight velocity and body mass index among Norwegian children from 1 month to 8 years. The study population included 59,927 family/children pairs participating in the Norwegian Mother, Father, and Child Cohort Study. Growth was modelled using the Jenss–Bayley model and linear mixed effects analyses were conducted. Maternal and paternal educational differences in children’s weight and BMI trajectories emerged during infancy, continuing to age 8 years. Parental income-related inequalities in children’s weight were observed from the age of 1 month to 4 years for maternal and up to 1 year for paternal income-related differences but then disappeared. Parental income-related inequalities in child’s BMI were observed from 18 months to 8 years for maternal income, and from 9 months to 8 years for paternal income-related differences. These results suggest that social inequalities in children’s BMI present early in infancy and continue to 8 years of age. The inequalities sometimes differed by indicator of socioeconomic position used. Interventions to combat these inequalities early in life are, thus needed.

BACKGROUND: We investigated preoperative cerebral (ScO2) and abdominal (StO2) regional oxygen saturations according to cardiac diagnosis in neonates with critical CHD, their time trends, and the clinical and biochemical parameters associated with them. METHODS: Thirty-seven neonates with a prenatal diagnosis of CHD were included. ScO2 and StO2 values were continuously evaluated using near-infrared spectroscopy. Measurements were obtained hourly before surgery. A linear mixed effects model was used to assess the effects of time and cardiac diagnosis on regional oxygenation and to explore the contributing factors. RESULTS: Regional oxygenation differed according to cardiac diagnosis (p < 0.001). ScO2 was lowest in the patients with severe atrioventricular valvar regurgitation (AVVR) (48.1 ± 8.0%). StO2 tended to be lower than ScO2, and both worsened gradually during the period between birth and surgery. There was also a significant interaction between cardiac diagnosis and time. The factors related to ScO2 were hemoglobin and arterial saturation, whereas no factor was associated with StO2. CONCLUSIONS: Preoperative ScO2 and StO2 in critical CHD differed according to cardiac diagnosis. ScO2 in the patients with severe AVVR was very low, which may imply cerebral hypoxia. ScO2 gradually decreased, suggesting that the longer the time to surgery, the higher the risk of hypoxic brain injury.

Cognate similarity and intervocalic /d/ production in Riverense Spanish

Aims and objectives: While previous research has shown that phonetic variation in language contact situations is affected by whether a word has a cognate in the contact language, this paper aims to show that such an effect is not monotonic. According to the usage-based model, items in memory are organized according to similarity, thus we anticipated that formally more similar cognates would show a stronger cognate effect. Methodology: This variationist sociophonetic study investigates the relationship between cognate similarity and phonetic realization. We examined this relationship in the bilingual community of Rivera, Uruguay, in which both Portuguese and Spanish are spoken with regularity. Specifically, we focused on intervocalic /d/, which in monolingual Spanish is realized as an approximant [ð̞] or phonetic zero, but in monolingual Brazilian Portuguese is produced as a stop [d] or, in most varieties, an affricate [ʤ] before [i]. Data and analysis: We analyzed a corpus of sociolinguistic interviews of the Spanish spoken in Rivera. Acoustic measurements were taken from approximately 60 tokens each from 40 different speakers. Using a linear mixed-effects model, we examined the relationship between several predictors and the degree of constriction of intervocalic /d/. Findings/conclusions: While there is an overall frequency effect whereby more frequent words exhibit less constriction of intervocalic /d/, as both frequency and cognate similarity increase, less constriction of intervocalic /d/ obtains. Therefore, frequent cognates in Portuguese that have very similar forms affect the production of intervocalic /d/ more so than other cognates. Originality: No previous study has demonstrated that the cognate effect on phonetic variation in a situation of language contact is regulated by form similarity between cognate pairs. Significance/implications: The data support the usage-based model in that similar cognates have more lexical connections and can therefore show greater influence on phonetic realization than can cognates that share less phonetic material.

Abstract This research communication describes the relationship between the occurrence of lameness and body condition score (BCS) in a sample of 288 cows from a single farm that were repeatedly scored in the course of 9 months while controlling for confounding variables. The relationship between BCS and lameness was evaluated using generalised linear mixed-effects models. It was found that the proportion of lame cows was higher with decreasing but also with increasing BCS, increased with lactation number and decreased with time since the last claw trimming. This is likely to reflect the importance of sufficient body condition in the prevention of lameness but also raises the question of the impact of overcondition on lameness and the influence of claw trimming events on the assessment of lameness. A stronger focus on BCS might allow improved management of lameness that is still one of the major problems in housed cows.
