Islamophobes are not all the same! A study of far right actors on Twitter

Far-right actors are often purveyors of Islamophobic hate speech online, using social media to spread divisive and prejudiced messages which can stir up intergroup tensions and conflict. Hateful content can inflict harm on targeted victims, create a sense of fear amongst communities and stir up intergroup tensions and conflict. Accordingly, there is a pressing need to better understand at a granular level how Islamophobia manifests online and who produces it. We investigate the dynamics of Islamophobia amongst followers of a prominent UK far right political party on Twitter, the British National Party. Analysing a new data set of five million tweets, collected over a period of one year, using a machine learning classifier and latent Markov modelling, we identify seven types of Islamophobic far right actors, capturing qualitative, quantitative and temporal differences in their behaviour. Notably, we show that a small number of users are responsible for most of the Islamophobia that we observe. We then discuss the policy implications of this typology in the context of social media regulation

Are We Closer to International Consensus on the Term 'Food Literacy'? A Systematic Scoping Review of Its Use in the Academic Literature (1998-2019).

(1) Background: The term 'food literacy' has gained momentum globally; however, a lack of clarity around its definition has resulted in inconsistencies in use of the term. Therefore, the objective was to conduct a systematic scoping review to describe the use, reach, application and definitions of the term 'food literacy' over time. (2) Methods: A search was conducted using the PRISMA-ScR guidelines in seven research databases without any date limitations up to 31 December 2019, searching simply for use of the term 'food literacy'. (3) Results: Five hundred and forty-nine studies were included. The term 'food literacy' was used once in 243 articles (44%) and mentioned by researchers working in 41 countries. Original research was the most common article type (n = 429, 78%). Food literacy was published across 72 In Cites disciplines, with 456 (83%) articles from the last 5 years. In articles about food literacy (n = 82, 15%), review articles were twice as prevalent compared to the total number of articles (n = 10, 12% vs. n = 32, 6%). Fifty-one different definitions of food literacy were cited. (4) Conclusions: 'Food literacy' has been used frequently and broadly across differing article types and disciplines in academic literature internationally. However, agreement on a standardised definition of food literacy endorsed by a peak international agency is needed in order to progress the field

Recalibrating classifiers for interpretable abusive content detection

Dataset and code for the paper, 'Recalibrating classifiers for interpretable abusive content detection' by Vidgen et al. (2020) -- to appear at the NLP + CSS workshop at EMNLP 2020. We provide: 1,000 annotated tweets, sampled using the Davidson classifier with 20 0.05 increments (50 from each) from a dataset of tweets directed against MPs in the UK 2017 General Election 1,000 annotated tweets, sampled using the Perspective classifier with 20 0.05 increments (50 from each) from a dataset of tweets directed against MPs in the UK 2017 General Election Code for recalibration in R and STAN. Annotation guidelines for both datasets. Paper abstract We investigate the use of machine learning classifiers for detecting online abuse in empirical research. We show that uncalibrated classifiers (i.e. where the 'raw' scores are used) align poorly with human evaluations. This limits their use to understand the dynamics, patterns and prevalence of online abuse. We examine two widely used classifiers (created by Perspective and Davidson et al.) on a dataset of tweets directed against candidates in the UK's 2017 general election. A Bayesian approach is presented to recalibrate the raw scores from the classifiers, using probabilistic programming and newly annotated data. We argue that interpretability evaluation and recalibration is integral to the application of abusive content classifiers

Introducing CAD: the Contextual Abuse Dataset

Online abuse can inflict harm on users and communities, making online spaces unsafe and toxic. Progress in automatically detecting and classifying abusive content is often held back by the lack of high quality and detailed datasets.We introduce a new dataset of primarily English Reddit entries which addresses several limitations of prior work. It (1) contains six conceptually distinct primary categories as well as secondary categories, (2) has labels annotated in the context of the conversation thread, (3) contains rationales and (4) uses an expert-driven group-adjudication process for high quality annotations. We report several baseline models to benchmark the work of future researchers. The annotated dataset, annotation guidelines, models and code are freely available

Rise and demise: a case study of public health nutrition in Queensland, Australia, over three decades

This case study describes the delivery and achievements of the public health nutrition programme in Queensland, Australia, over more than three decades. Analysis of publicly available documents related to statewide nutrition policy and programmes from 1983 to 2014 identified key inputs and programme impacts and outcomes, including an increase in fruit and vegetable intake by 1.1 serves per person per day and rates of exclusive breastfeeding for the first 6 months quadrupled. Mapping factors and milestones against a framework on determinants of political priority highlighted correlation with effective nutrition promotion policy and practice. Identified enablers included the influence of policy champions and advocates, quality of governance, focus on whole-of-population approaches, and periods of political will and economic prosperity. Key barriers included changes of ideology with government leadership; lack of commitment to long-term implementation and evaluation; and limited recognition of and support for preventive health and nutrition promotion. The case study shows that a coordinated, well-funded, intersectoral approach to improve nutrition and prevent chronic disease and malnutrition in all its forms can be achieved and produce promising impacts at state level, but that sustained effort is required to secure and protect investment. Political support for long-term investment in nutrition is essential to reduce the high cost of all diet-related diseases. Public health leadership to better prepare for risks around political cycles, secure adequate resources for evaluation, and better communicate impacts and outcomes may help protect future investments and achievements

Enrolment of families with overweight children into a program aimed at reducing childhood obesity with and without a weight criterion: a natural experiment

The Creative Commons Public Domain Dedication waiver (http://creativecommons.org/publicdomain/zero/1.0/) applies to the data made available in this article, unless otherwise stated.BACKGROUND: Difficulties engaging families with overweight children to enrol into programs aimed at reducing childhood obesity have been well documented. During the implementation of the Parenting, Eating and Activity for Child Health Program (PEACH™) over a large geographical area (Queensland (QLD), Australia), a natural experiment developed. This experiment provided an opportunity to observe if there was a difference in enrolment for families with overweight children with a weight criterion (referred to as the period with a Targeted Eligibility Criterion (TEC)) compared to when a weight criterion was removed (the period referred to as Universal Eligibility Criterion (UEC)). We also examined the eligibility criterion’s relationship with attendance, parental concern about their child’s weight, estimation of overweight and obesity from parent-reported data. METHODS: A secondary analysis of baseline data from 926 overweight/obese children from 817 families enrolled in PEACH™ QLD was performed. Analyses were adjusted to control for the presence of clustered data. Bivariate statistics were performed using Pearson chi-square test with the second-order Rao-Scott correction, and Mann–Whitney U-test for non-parametric continuous variables. Generalized Estimating Equations (GEE) explored the association between weight status-based eligibility criteria and enrolment of overweight children. GEE were adjusted for sex, age and socioeconomic index and stratified for weight category. RESULTS: Compared to obese children, overweight children were almost twice as likely to be enrolled when the program did not have weight status-based eligibility criteria (during UEC period) (OR = 1.90 (CI 95% 1.35–2.68, p <  0.001)). Parents of overweight children enrolled during the UEC period were more likely to regard their child’s weight as less of a concern than during the TEC period (UEC 67% vs. TEC 45%, p = 0.036). Children whose parent-reported data underestimated their weight category were more likely to be enrolled while the program did not have weight-related eligibility criteria OR = 2.27 (CI 1.38–3.70, p <  0.01). Program session attendance did not appear to be impacted by the changes in eligibility criteria. CONCLUSIONS: The omission of weight criteria for healthy lifestyle programs is a consideration for health professionals and decision-makers alike when encouraging the enrolment of children who are overweight into healthy lifestyle programs

The extent and nature of children’s involvement in food practice research: a scoping review of qualitative studies

Abstract Objective: Aligning with the United Nations Convention on the Rights of the Child, amplification of children’s voice in food practice research aims to inform initiatives that cater to children’s needs and thus improve nutritional outcomes. The aim of this study was to describe children’s (aged 6–11 years) involvement across qualitative research investigating their food practice perspectives. Design: A scoping review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews (PRISMA-ScR). Six electronic databases were searched up until March 2023 (Cochrane, CINAHL, Embase, ERIC, Medline and PsychInfo). The Wellcome Framework for young people’s involvement in health research guided data extraction. Data were described according to inclusiveness, geography, food-related study topic, research stage and method, and child involvement. Results: The search identified 120 peer-reviewed studies (134 papers). Active participation was only seen within research implementation stages (i.e. data collection (n 134), analysis (n 31), dissemination (n 9) and re-design (n 7)). More passive forms of participation were identified in research design stages (i.e. agenda setting, resourcing and design). Studies that utilised participatory research methodologies and developmentally appropriate and engaging methods (e.g. PhotoVoice) saw more active participation by children. Conclusion: This review identified a lack of opportunities for children’s active participation in all stages of food practice research. Without a radical shift towards providing these opportunities, food and nutrition initiatives, policies or further research that do not meet the needs of children’s food-related worlds will continue to be developed. Instead, researchers and their institutions need to advocate for and, where possible, provide voluntary opportunities for children to actively participate in food practice research
