“When they go low, we kick them”
Pushing and Pulling
Distrust is widely argued to stimulate support for political and institutional change. Yet, there is little agreement among scholars whether distrust pulls people towards rivaling decision-making models such as direct democracy, technocracy, and authoritarianism. This paper argues that political distrust is an unconditional push-factor away from the status quo (i.e., representative democracy), but that the appeal of any specific alternative decis…
Breaking free from linear assumptions
Scholars increasingly raise concerns about the alleged detrimental impact of affective polarization on citizens’ democratic attitudes. Yet, prior studies on the relationship between affective polarization and democratic support have yielded mixed results: Whereas some scholars report evidence that affective polarization erodes citizens’ support for democracy, others report null findings. In this research note, we posit that one relevant explanati…
Sweet victory, bitter defeat
Accepting defeat in the aftermath of elections is crucial for the stability of democracies. But in times of intense polarization, the voluntary consent of electoral losers seems less obvious. In this paper, I study whether affective and perceived ideological polarization amplify the winner–loser gap in political support. Using multilevel growth curve modelling on pre and post‐election panel data from the British Election Study Internet Panel coll…
Privatization of preschool education
Preschool education is regarded by many researchers and policymakers as a potential equalizer of educational opportunities. Yet, cross-national research shows that there exist large variations in the equalizing effects of preschool education across countries. In this paper, we study to what extent the national level of privatization of the preschool sector can explain these cross-national differences by examining its impact on the equalizing effe…
The predictive value of polls in a fragmented multi-party system
Enhancing the potential effects of text messages delivered via an m-health intervention to improve packing of healthy school lunchboxes
Objective: The aim of the study was to assess the impact of different lunchbox messages on parents’ intention to pack a healthy lunchbox. Design: This study employed an experimental design. Setting: A series of messages were developed to align with the six constructs of the Health Belief Model. Messages were also developed that were (and were not) personalised and varied based on the source of the information provided (university, school, dietiti…
A cross-sectional study to determine the energy density and nutritional quality of primary-school children’s lunchboxes
Objective: The present study describes the energy content of primary-school children’s lunchboxes and the proportion of lunchbox foods considered discretionary. Subgroup analyses by sex, socio-economic status, age and weight status were undertaken. Design: A cross-sectional study was conducted. Mean kilojoule content, number of items and categorisation of foods and drinks in lunchboxes as ‘everyday’ (healthy) or discretionary (sometimes) foods we…
Protocol for an effectiveness- implementation hybrid trial to assess the effectiveness and cost-effectiveness of an m-health intervention to decrease the consumption of discretionary foods packed in s…

A cross-sectional study of the nutritional quality of student canteen purchases from New South Wales primary-school canteens
Objective: To assess the nutritional quality of student canteen purchases at recess and lunch, including: (i) the mean energy (kilojoules), saturated fat (grams), total sugar (grams) and Na (milligrams) and percentage of energy from saturated fat and total sugar; and (ii) the proportion and types of foods purchased that are healthier (green) and less healthy (amber/red) according to a state school canteen policy. Design: A cross-sectional study o…
Availability of food and beverage items on school canteen menus and association with items purchased by children of primary-school age
Objective To (i) describe the proportion of foods and beverages available on school canteen menus classified as having high (‘green’), moderate (‘amber’) or low (‘red’) nutritional value; (ii) describe the proportion of these items purchased by students; and (iii) examine the association between food and beverage availability on school canteen menus and food and beverage purchasing by students. Design A cross-sectional study was conducted as part…
