The Impact

Shifting people in higher income countries toward more plant-based diets would protect the natural environment and improve population health. Research in other domains suggests altering the physical environments in which people make decisions (“nudging”) holds promise for achieving socially desirable behavior change. Here, we examine the impact of attempting to nudge meal selection by increasing the proportion of vegetarian meals offered in a year-long large-scale series of observational and experimental field studies. Anonymized individual-level data from 94,644 meals purchased in 2017 were collected from 3 cafeterias at an English university. Doubling the proportion of vegetarian meals available from 25 to 50% (e.g., from 1 in 4 to 2 in 4 options) increased vegetarian meal sales (and decreased meat meal sales) by 14.9 and 14.5 percentage points in the observational study (2 cafeterias) and by 7.8 percentage points in the experimental study (1 cafeteria), equivalent to proportional increases in vegetarian meal sales of 61.8%, 78.8%, and 40.8%, respectively. Linking sales data to participants’ previous meal purchases revealed that the largest effects were found in the quartile of diners with the lowest prior levels of vegetarian meal selection. Moreover, serving more vegetarian options had little impact on overall sales and did not lead to detectable rebound effects: Vegetarian sales were not lower at other mealtimes. These results provide robust evidence to support the potential for simple changes to catering practices to make an important contribution to achieving more sustainable diets at the population level.

The Impact

Corruption is a phenomenon that affects societies. It lowers trust in public institutions, lowers trust among people, undermines economic development, undermines democracy, and has implications for political participation. This article contributes to current debates on the impact of corruption by looking at other possible consequences of corruption. Specifically, this article looks at the impact of the perception of corruption on the approval of public protest meetings and demonstrations because, if corruption leads to these non-institutionalized forms of political participation, this may lead to security problems or a direct outbreak of violence. This study analyses this relationship by using seven post-communist countries that have undergone specific developments in terms of corruption. These developments were largely due to large-scale privatizations, politicized state administration, and the linking of politicians to the private sector. This research was conducted with individual-level data. The module ‘The Role of Government V’ from the International Social Survey Programme was used. Descriptive charts have revealed that in six out of the seven countries, most respondents considered politicians to be very corrupt. Around 80% of respondents in all seven countries approve of the organization of public protest meetings. Around 70% of respondents in all seven countries approve of demonstrations. Regression analysis revealed that there is a relationship between the perception of corruption among politicians and the approval of protest activities. Specifically, the more politicians are corrupt, the more people approve of holding public protest meetings and demonstrations.

Abstract Background Area-level deprivation is well known to have an adverse impact on mortality, morbidity, or other specific health outcomes. This study examined how area-level deprivation may affect self-rated health (SRH) and life satisfaction (LS), an issue that is largely understudied. Methods We used individual-level data obtained from a nationwide population-based internet survey conducted between 2019 and 2020, as well as municipality-level data obtained from a Japanese government database (N = 12,461 living in 366 municipalities). We developed multilevel regression models to explain an individual’s SRH and LS scores using four alternative measures of municipality-level deprivation, controlling for individual-level deprivation and covariates. We also examined how health behavior and interactions with others mediated the impact of area-level deprivation on SRH and LS. Results Participants in highly deprived municipalities tended to report poorer SRH and lower LS. For example, when living in municipalities falling in the highest tertile of municipality-level deprivation as measured by the z-scoring method, SRH and LS scores worsened by a standard deviation of 0.05 (p < 0.05) when compared with those living in municipalities falling in the lowest tertile of deprivation. In addition, health behavior mediated between 17.6 and 33.1% of the impact of municipality-level deprivation on SRH and LS, depending on model specifications. Conclusion Results showed that area-level deprivation modestly decreased an individual’s general health conditions and subjective well-being, underscoring the need for public health policies to improve area-level socioeconomic conditions.

The Impact

In 2002, Florida adopted a test-based promotion policy in the third grade in an attempt to end social promotion. Similar policies are currently operating in Texas, New York City, and Chicago and affect at least 17 percent of public school students nationwide. Using individual-level data on the universe of public school students in Florida, we analyze the impact of grade retention on student proficiency in reading one and two years after the retention decision. We use an instrumental variable (IV) approach made available by the relatively objective nature of Florida's policy. Our findings suggest that retained students slightly outperformed socially promoted students in reading in the first year after retention, and these gains increased substantially in the second year. Results were robust across two distinct IV comparisons: an across-year approach comparing students who were essentially separated by the year in which they happened to have been born, and a regression discontinuity design.

The Impact

Background: Britain’s National Surveys of Sexual Attitudes and Lifestyles (Natsal) have been undertaken decennially since 1990 and provide a key data source underpinning sexual and reproductive health (SRH) policy. The COVID-19 pandemic disrupted many aspects of sexual lifestyles, triggering an urgent need for population-level data on sexual behaviour, relationships, and service use at a time when gold-standard in-person, household-based surveys with probability sampling were not feasible. We designed the Natsal-COVID study to understand the impact of COVID-19 on the nation’s SRH and assessed the sample representativeness. Methods: Natsal-COVID Wave 1 data collection was conducted four months (29/7-10/8/2020) after the announcement of Britain’s first national lockdown (23/03/2020). This was an online web-panel survey administered by survey research company, Ipsos MORI. Eligible participants were resident in Britain, aged 18-59 years, and the sample included a boost of those aged 18-29. Questions covered participants’ sexual behaviour, relationships, and SRH service use. Quotas and weighting were used to achieve a quasi-representative sample of the British general population. Participants meeting criteria of interest and agreeing to recontact were selected for qualitative follow-up interviews. Comparisons were made with contemporaneous national probability surveys and Natsal-3 (2010-12) to understand bias. Results: 6,654 participants completed the survey and 45 completed follow-up interviews. The weighted Natsal-COVID sample was similar to the general population in terms of gender, age, ethnicity, rurality, and, among sexually-active participants, numbers of sexual partners in the past year. However, the sample was more educated, contained more sexually-inexperienced people, and included more people in poorer health. Conclusions: Natsal-COVID Wave 1 rapidly collected quasi-representative population data to enable evaluation of the early population-level impact of COVID-19 and lockdown measures on SRH in Britain and inform policy. Although sampling was less representative than the decennial Natsals, Natsal-COVID will complement national surveillance data and Natsal-4 (planned for 2022).

Abstract In this chapter, we focus on mathematical models of tuberculosis epidemiology (TB) that include interactions with HIV and an explicit representation of transmission. We review the natural history of TB and illustrate how its features are simplified and incorporated in mathematical models. We then review the ways HIV influences the natural history of TB, the interventions that have been considered in models, and the way these individual-level effects are represented in models. We then go on to consider population-level effects, reviewing the TB/HIV modelling literature. We first review studies whose focus was on purely epidemiological modelling, and then studies whose focus was on modelling the impact of interventions. We conclude with a summary of the uses and achievements of TB/HIV modelling and some suggested future directions.

AbstractThis article contests the view that the strong positive correlation between anti-immigration attitudes and far right party success necessarily constitutes evidence in support of the cultural grievance thesis. We argue that the success of far right parties depends on their ability to mobilize a coalition of interests between their core supporters, that is voters with cultural grievances over immigration and the often larger group of voters with economic grievances over immigration. Using individual level data from eight rounds of the European Social Survey, our empirical analysis shows that while cultural concerns over immigration are a stronger predictor of far right party support, those who are concerned with the impact of immigration on the economy are important to the far right in numerical terms. Taken together, our findings suggest that economic grievances over immigration remain pivotal within the context of the transnational cleavage.

Original Approach

This exploratory article aims to take first steps towards understanding whether a regional cultural background has, among other determinants, an influence on a person’s entrepreneurial behaviour, relying on the example of Germany. A multilevel approach is applied combining the Global Entrepreneurship Monitor individual-level data about entrepreneurship with up-to-date cultural dimensions indicators based on Hofstede’s original approach at the regional (NUTS 1) level. The results indicate that regional cultural context is an important determinant of entrepreneurial behaviour. At that, different cultural dimensions have different impacts, and the impact also differs across different stages of entrepreneurship. A lower level of uncertainty avoidance in a region could have a positive impact on early-stage entrepreneurship, whereas the established business ownership seems to be encouraged by a lower level of power distance.

Service Attendance

During the long nineteenth century, Poland was divided among the Russian, Habsburg, and Prussian empires. The partition produced regional diversity in political culture and in institutional and economic development. We examine how the cultural legacies of the empires have influenced the propensity of Poles to cast a ballot in parliamentary elections since 1989. Polish National Election Study individual-level data are used to assess whether higher levels of electoral turnout in Galicia are indeed a legacy of the Habsburg rule. Our results confirm that, even after controlling for socio-demographic factors, there is a positive, substantive, and significant effect on turnout of living in the ex-Habsburg part of Poland. This effect can be explained by the frequency of religious service attendance and by ideology. Inhabitants of Galicia not only attend religious services more frequently and are more conservative than their counterparts in the rest of Poland, but also the more frequently they attend church and the closer to the radical right they place themselves, the more mobilized they are to vote. The impact of the legacies of the empires on political behavior in Poland seems persistent.

AbstractWe examine the impact of the current economic crisis on the accuracy of responsibility attribution between levels of government within states. Using individual-level data from Spain, we show that learning about responsibility attribution depends on the saliency of the issue (in our study, unemployment) and economic self-interest. The (unintended) positive consequence of economic crisis is that citizens are now more able to accurately attribute the responsibility for political decisions than some years ago. Learning is particularly significant among those individuals more affected by the economic crisis.

The Impact

All educational testing is intended to have consequences, which are assumed to be beneficial, but tests may also have unintended, negative consequences (Messick, 1989). The issue is particularly important in the case of large-scale standardized tests, such as Australia’s National Assessment Program - Literacy and Numeracy (NAPLAN), the intended benefits of which are increased accountability and improved educational outcomes. The NAPLAN purpose is comparable to that of other state and national ‘core skills’ testing programs, which evaluate cross-sections of populations in order to compare results between population sub-groupings. Such comparisons underpin ‘accountability’ in the era of population-level testing. This study investigates the impact of NAPLAN testing on one population grouping that is prominent in the NAPLAN results’ comparisons and public reporting: children in remote Indigenous communities. A series of interviews with principals and teachers documents informants’ first-hand experiences of the use and effects of NAPLAN in schools. In the views of most participants, the language and content of the test instruments, the nature of the test engagement, and the test washback have negative impacts on students and staff, with little benefit in terms of the usefulness of the test data. The primary issue is the fact that meaningful participation in the tests depends critically on proficiency in Standard Australian English (SAE) as a first language. This study contributes to the broader discussion of how reform-targeted standardized testing for national populations affects sub-groups who are not treated equitably by the test instrument or reporting for accountability purposes. It highlights a conflict between consequential validity and the notion of accountability that drives reform-targeted testing.
