Gender and family-role portrayals of autism in British newspapers:An intersectional corpus-based study

A recent large-scale study on the portrayal of autism in British newspapers revealed a deficit-based coverage, which concentrated on children and boys in particular, typically represented from the mothers' perspective. This follow-up study refines these representations, considering how they differ by gender and family role. We analysed 2,998 text samples, which discussed autism in the context of four combinations of gender and family roles, namely, BOY, GIRL, FATHER, and MOTHER. These samples included sources with different publication date, reporting style, and political orientation. Autism representations remained negative regardless of gender and family role. Over time, stories about autistic girls started to emerge, identifying them as a distinct group explicitly compared to autistic boys. Newspapers, especially broadsheets, associated girls with diagnostic difficulties, camouflaging, and sometimes gender dysphoria − discussed particularly for children assigned female at birth. The child's autism was more often attributed to maternal than paternal behaviours or lifestyle. Autistic mothers were mentioned more often than fathers, and were portrayed negatively. We conclude that newspapers portray female autism as less significant than male autism, and, in addition, place mothers under more ethical scrutiny than fathers. These disparities reflect both historical biases in autism research and gender and family-role stereotypes

Maternal Responses in the Face of Infection Risk

When animals are sick, their physiology and behavior change in ways that can impact their offspring. Research is emerging showing that infection risk alone can also modify the physiology and behavior of healthy animals. If physiological responses to environments with high infection risk take place during reproduction, it is possible that they lead to maternal effects. Understanding whether and how high infection risk triggers maternal effects is important to elucidate how the impacts of infectious agents extend beyond infected individuals and how, in this way, they are even stronger evolutionary forces than already considered. Here, to evaluate the effects of infection risk on maternal responses, we exposed healthy female Japanese quail to either an immune-challenged (lipopolysaccharide [LPS] treated) mate or to a healthy (control) mate. We first assessed how females responded behaviorally to these treatments. Exposure to an immune-challenged or control male was immediately followed by exposure to a healthy male, to determine whether treatment affected paternity allocation. We predicted that females paired with immune-challenged males would avoid and show aggression towards those males, and that paternity would be skewed towards the healthy male. After mating, we collected eggs over a 5-day period. As an additional control, we collected eggs from immune-challenged females mated to healthy males. We tested eggs for fertilization status, embryo sex ratio, as well as albumen corticosterone, lysozyme activity, and ovotransferrin, and yolk antioxidant capacity. We predicted that immune-challenged females would show the strongest changes in the egg and embryo metrics, and that females exposed to immune-challenged males would show intermediate responses. Contrary to our predictions, we found no avoidance of immune-challenged males and no differences in terms of paternity allocation. Immune-challenged females laid fewer eggs, with an almost bimodal distribution of sex ratio for embryos. In this group, albumen ovotransferrin was the lowest, and yolk antioxidant capacity decreased over time, while it increased in the other treatments. No differences in albumen lysozyme were found. Both females that were immune-challenged and those exposed to immune-challenged males deposited progressively more corticosterone in their eggs over time, a pattern opposed to that shown by females exposed to control males. Our results suggest that egg-laying Japanese quail may be able to respond to infection risk, but that additional or prolonged sickness symptoms may be needed for more extensive maternal responses

The Environmental Impact of Lowering Dietary Crude Protein in Finishing Pig Diets—The Effect on Ammonia, Odour and Slurry Production

Publication history: Accepted - 20 September 2022; Published - 23 September 2022.Excess nitrogen excretion, ammonia and odour are environmental pollutants associated with pig production. Reducing dietary crude protein (CP) will lower the amount of nitrogen excreted, reducing the potential for ammonia emissions, if diets are adequately formulated to supply amino acids and production performance is maintained. Crude protein content in diets for finishing pigs has been lowered recently, but the quantitative effect of this reduction on ammonia, odour, and slurry output is not well-established. The relationship between ammonia and odour is equivocal, and the effect on slurry production is unclear. The objective of this study was to investigate the effect of lowering dietary CP on ammonia emission, odour emission and slurry output of finishing pigs. Thirty entire boar pigs were individually housed in groups of six, from 10 weeks of age (30 3.0 kg) and offered standard diets. At 75 kg ( 1.5 kg) pigs were assigned to one of three treatment diets; (1) 180 g/kg CP, 11.0 g/kg total lysine (High CP), (2) 150 g/kg CP, 11.1 g/kg total lysine (Medium CP), and (3) 130 g/kg CP, 9.0 g/kg total lysine (Low CP). After three weeks on the experimental diets pigs were moved, six each week, to individual calorimetry chambers to measure ammonia and odour emissions. Pigs were offered treatment diets ad libitum. At the end of the recording period, the pigs were removed from the chamber, weighed and feed disappearance recorded to calculate intake. The slurry in each chamber was collected and analysed. The reduction in CP in the diet from 180 g/kg to 150 g/kg resulted in a 22% reduction in ammonia emissions, and from 180 g/kg to 130 g/kg resulted in a 47% reduction (p < 0.001). Slurry output from pigs offered the 130 g/kg CP diet was reduced by 39% (p < 0.001) and dry matter increased by 35% compared to slurry from pigs offered the 180 g/kg CP diet (p < 0.05). Water usage (p = 0.017), slurry output and nitrogen and phosphate in the slurry (p < 0.05, respectively) were found to decrease linearly with decreasing dietary CP content. There was no significant effect of reducing CP on performance or odour emission but hydrogen sulphide emissions decreased linearly (p < 0.010) with decreasing dietary CP. There was a weak positive relationship between odour emission and ammonia (linear: R2 = 0.25, p = 0.005) with odour emission reduced as ammonia emission reduced. Reducing dietary CP in finishing pig diets could reduce ammonia emissions, water usage and slurry and nutrient output from pig production.This work was funded by the Department of Agriculture, Environment and Rural Affairs under Evidence and Innovation Project 15/01/01 with industry contribution from the partners of the Pig Research Consortium

Population analysis of the GLB1 gene in South Brazil

Infantile GM1 gangliosidosis is caused by the absence or reduction of lysosomal beta-galactosidase activity. Studies conducted in Brazil have indicated that it is one of the most frequent lysosomal storage disorders in the southern part of the country. To assess the incidence of this disorder, 390 blood donors were tested for the presence of two common mutations (1622–1627insG and R59H) in the GLB1 gene. Another group, consisting of 26 GM1 patients, and the blood donors were tested for the presence of two polymorphisms (R521C and S532G), in an attempt to elucidate whether there is a founder effect. The frequencies of the R59H and 1622–1627insG mutations among the GM1 patients studied were 19.2% and 38.5%, respectively. The frequency of polymorphism S532G was 16.7%, whereas R521C was not found in the patients. The overall frequency of either R59H or 1622–1627insG was 57.7% of the disease-causing alleles. This epidemiological study suggested a carrier frequency of 1:58. Seven different haplotypes were found. The 1622–1627insG mutation was not found to be linked to any polymorphism, whereas linkage disequilibrium was found for haplotype 2 (R59H, S532G) (p < 0.001). These data confirm the high incidence of GM1 gangliosidosis and the high frequency of two common mutations in southern Brazil

Portrayals of autism in the British press:A corpus-based study

Press representations of autism and autistic people both reflect and help shape public attitudes towards autism and neurodiversity and may establish critical barriers to social integration for autistic individuals. This study examined such representations in UK newspapers in the period 2011–2020 using a corpus-based approach. It also considered how press representations changed over time and differed with regard to reporting style (tabloids vs broadsheets) and political orientation (left- vs right-leaning). We created the Autism UK Press Corpus, which included all documents (~24K) referring to autism in 10 national newspapers. We used document counts (normalised by newspaper size) to assess the ‘newsworthiness’ of autism. We also employed a synergy of corpus-based and critical-discourse-analysis methodologies to study lexicogrammatical patterns and uncover explicit and implicit attitudes towards autism. Our results showed that the coverage of autism increased slightly over time, especially in broadsheets and left-leaning newspapers. Newspapers emphasised adversities associated with autism, often used negative language, and tended to focus on boys. These representations shifted gradually towards more difference-based descriptions and included more diverse age/gender groups, especially in broadsheets and left-leaning newspapers. We discuss the broad implications of these findings for the autism community and those interested in a more inclusive society. Lay abstract Any thriving society must recognise, accept and celebrate all of its diverse talent. But how accepting is British society towards autism and autistic people? This research addressed this question through the lens of the press since the press both reflects and helps shape public attitudes towards various social categories. We used specialised ‘corpus-based’ methods to carry out a large-scale study, which examined all articles referring to autism or autistic people in 10 national British newspapers in the period 2011–2020. We first investigated how often newspapers referred to autism. We found that the coverage of autism increased slightly over the years, suggesting that autism was becoming an increasingly newsworthy topic. Furthermore, the rise in autism coverage differed considerably between individual newspapers: it was more pronounced in the broadsheets than tabloids, and in left-leaning than right-leaning newspapers. But what was the focus of these articles? We found that newspapers emphasised the adversities associated with autism and portrayed autism with a lot of negative language. Newspapers also tended to focus on autistic children, and particularly on boys. There were some signs of change in more recent years, with some newspapers now representing autism as a difference and, in addition, referring to more diverse groups of autistic people. However, these changes tended to be confined to broadsheets and left-leaning newspapers. Our findings suggest that representations of autism in the contemporary British press are skewed towards stereotypically negative views, which may well hinder the acceptance of autism and the fostering of a more inclusive society
