How Accurate Are Survey Responses on Social Media and Politics?

How accurate are survey-based measures of social media use, in particular about political topics? We answer this question by linking original survey data collected during the U.S. 2016 election campaign with respondents’ observed social media activity. We use supervised machine learning to classify whether these Twitter and Facebook account data are content related to politics. We then benchmark our survey measures on frequency of posting about politics and the number of political figures followed. We find that, on average, our self-reported survey measures tend to correlate with observed social media activity. At the same time, we also find a worrying amount of individual-level discrepancy and problems related to extreme outliers. Our recommendations are twofold. The first is for survey questions about social media use to provide respondents with options covering a wider range of activity, especially in the long tail. The second is for survey questions to include specific content and anchors defining what it means for a post to be “about politics.”     

Reality Shock and Public Service Motivation: A Longitudinal,Qualitative Study Among Dutch Veterinary Inspectors

To this day little is known about the mechanisms that help explain the mixed findings of longitudinal public service motivation (PSM) research. This study aims to deepen our understanding of post-entry PSM dynamics by focusing on the role of the often cited “reality shock” as a potential explanation for the decrease in PSM also found here. The results of this longitudinal, small-scale qualitative study of a specific cohort of newcomers who just started work as veterinary inspectors at the Dutch food safety authority suggest that a loss of PSM is not due to a generic shock effect, but is linked to having unclear job expectations and individual differences in coping behaviour.     

The Body Perfect Ideal and Eating Regulation Goals: Investigating the Role of Adolescents’ Identity Styles

Adolescents are exposed to images depicting the thin or muscular ideal almost on a daily basis. When the body perfect ideal is adopted, adolescents are at increased risk for developing unhealthy and disordered eating behaviors. The aim of the current 3-wave longitudinal study among adolescents (N = 418; 54 % girls) was to investigate whether different styles of identity exploration (i.e., information-oriented, normative, and diffuse-avoidant) are associated differentially with changes in adoption of the body perfect ideal, which, in turn, would relate to changes in appearance-focused and health-focused eating regulation. Results indicated that the information-oriented style predicted decreases and the normative style predicted increases in adoption of the body perfect ideal. In turn, adoption of the body perfect ideal predicted significant increases in appearance-focused eating regulation but not in health-focused eating regulation. A diffuse-avoidant style was unrelated to changes in adoption of the body perfect, yet directly predicted decreases in health-focused eating regulation. Theoretical and clinical implications of these findings are discussed.     

Is All Politics Indeed Local? A Comparative Study of Dual Mandate‐Holders’ Role Attitudes and Behaviours in Parliament

The practice of dual mandate‐holding, i.e. the simultaneous occupation of a political mandate at the (sub)national and the local level, is understudied in the comparative literature. Dual mandate‐holders embody the most direct link between local and central government, yet research has disregarded whether these actors actually feel and act as local ambassadors in parliament. In this article, we study whether councillors in parliament feel responsive for local grievances in terms of their respective role attitudes and behaviour, using the PARTIREP Comparative MP Survey. The estimated regression models demonstrate that dual mandate‐holders indeed perceive themselves as local brokers, even when controlling for various systemic‐, party‐ and individual‐level factors. On the other hand, they struggle to translate their localized attitudes into localized parliamentary behaviour, which could call one of the main arguments in favour of dual mandate‐holding into question.

Sexual Debut Timing and Depressive Symptoms in Emerging Adulthood

The association between sexual debut timing and depressive symptomatology in adolescence and emerging adulthood was examined using data from Waves I, II and III of the National Longitudinal Study of Adolescent Health. Respondents who reported never having sexual intercourse at Wave I and were 18–22 years of age at Wave III were included (n = 5,061). Twenty percent of respondents experienced early (<age 16) and 49% experienced typical (ages 16–18) sexual debut. In bivariate analyses, pre-debut depressive symptoms were associated with earlier sexual debut among female but not male adolescents. In models adjusting for demographic characteristics and pre-debut depressive symptoms, sexual debut was positively related to adolescent (Wave II) depressive symptomatology, but only among female adolescents age less than sixteen. However, sexual debut timing was unassociated with emerging adult (Wave III) depressive symptomatology for both male and female respondents. Findings suggest sexual debut timing does not have implications for depressive symptomatology beyond adolescence.

Enhancing rural learning,linkages, and institutions: the rice videos in Africa

Africa Rice Center (WARDA) facilitated the development and translation of 11 rice videos. From 2005 to 2009, WARDA partners translated them into more than 30 African languages. Open-air video presentations enhanced learning, experimentation, confidence, trust, and group cohesion among rural people. The videos strengthened capacities of more than 500 organisations and hundreds of thousands of farmers. WARDA's integrated rural learning approach also helped women to access new markets and credit. Learning videos allow for unsupervised learning; unleash local creativity and experimentation; facilitate institutional innovations; and improve social inclusion of the poor, youth, and women.
