Maintaining participant engagement in longitudinal surveys has been a key focus of survey research, and has implications for the quality of response and cost of administration. This paper presents new research measuring the impact of the design of between-wave keeping-in-touch mailings on response to the mailing and subsequent wave of a longitudinal survey. Three design attributes of the mailings were randomly implemented: the form of response request (whether respondents were asked to respond only if their address had changed, or in all cases to confirm or update their address); the newsletter included with the mailing (contrasting a newsletter with content tailored to respondent characteristics with a general newsletter and no newsletter); and the outgoing postage used (stamped or franked). The experiments were fielded on a new longitudinal study, the English and Welsh Civil and Social Justice Panel Survey (CSJPS), and took place between waves one and two. Fieldwork for both waves was conducted by Ipsos MORI face-to-face interviewers. Our main finding was that the tailored newsletter was associated with a significant increase in the wave-two response rate. However, in relation to response to the request, the tailored newsletter, or sending no newsletter at all, were equally effective at inducing response, and significantly better than the general newsletter. We also found that, in relation to the form of request, the ‘change of address’ request was as effective as the more costly ‘confirmation’ request. Findings are discussed with reference to the design of keeping-in-touch mailings for longitudinal surveys.

In the fight against climate change, renewable energy has been subsidised in many countries. With the costs passed onto consumers, governments are paying those, for example, who instal domestic solar panels on top of their homes and feed electricity back into the system at preferential rates. We know that substantial amounts of income flow into households with solar installations as a result, but we do not know much about the political consequences of these programmes. Similar government programmes are known to have resource and interpretative effects on participants, leading to changes in their attitudes. Drawing on three longitudinal surveys from Germany, United Kingdom, and Switzerland, this article analyses whether installation of these solar panels causes meaningful changes in households’ various political attitudes. Using fixed-effect models as the identification strategy, the article reports null results – solar installations do not seem to generate political attitudes. This is good as well as bad news for actors looking to increase the amount of renewable energy produced through solar installations.

In March 2020, academic libraries across the United States closed and sent everyone home, some destined to not reopen for months. University offices closed. Classes were moved online. Suddenly, librarians and staff pivoted to working from home and to all remote services, without time for planning logistics or training. To study the impact of this extraordinary and sweeping transition on virtual reference services (VRS), we conducted a major study of academic library responses to the pandemic that focused on librarian perceptions of how services and relationships with users morphed during this COVID-19 year.Academic librarians rallied to our call, and we collected a total of 300 responses to two longitudinal surveys launched at key points during the pandemic. Data collection focused on two phases in 2020: 1) shutdown and immediate aftermath (mid-March to July), and 2) fall ramp up and into the semester (August to December). Via Zoom, we also interviewed 28 academic librarian leaders (e.g., heads of reference and/or VRS, associate directors for User Services) from September to November. Surveys and interviews centered on adaptations and innovations to reference services, especially VRS and perceptions of changes in user interactions.
