... This study reports the results of a multiyear program to predict direct executive elections in a variety of countries from globally pooled data.We developed prediction models by means of an election data set covering 86 countries and more than 500 elections, and a separate data set with extensive polling data from 146 election rounds.We also participated in two live forecasting experiments. Our models correctly predicted 80 to 90% of elections in out-of-sample tests. The results suggest that global elections can be successfully modeled and that they are likely to become more predictable as more information becomes available in future elections. The results provide strong evidence for the impact of political institutions and incumbent advantage. They also provide evidence to support contentions about the importance of international linkage and aid. Direct evidence for economic indicators as predictors of election outcomes is relatively weak. The results suggest that, with some adjustments, global polling is a robust predictor of election outcomes, even in developing states. Implications of these findings after the latest U.S. presidential election are discussed.

... How did anxiety influence voters' decisions in the 2016 presidential election? This study tests the hypothesis that voters who were anxious about their own party's candidate were less likely to vote based on partisanship and more likely to vote based on issue positions and candidate personal qualities. As part of the Election Research Preacceptance Competition 2016, this study has been designed with the 2016 American National Election Study codebook before the data are to be released. Hence, the documentation of this study shows how this analysis of anxiety's conditioning effect on vote choice is to be completed once the data are gathered. Documentation also shows how these data are to be cleaned with a program that cleans similar variables from the 2012 American National Election Study.

... Cores of the sediments from Oblong Tarn, Mount Kenya, were collected in 1983 and 1986, and were conventional radiocarbon dated to examine late Holocene glacier history of the mountain. Subsequently pollen samples were taken from both cores to create a composite pollen record.

... The IES is a five-yearly household survey based on the sample for the rotating panel of the twice yearly Labour force Survey (LFS). It measures the detailed income and expenditure of households. The survey was done by means of an interview with the household head or a responsible adult and the questionnaire was completed by the enumerator during this interview. In cases where the household requested to complete the questionnaire themselves, it was dropped off by the enumerator, and the completed questionnaire was collected at a second visit. There are 4 data files. General data: no cases; Home Grown Products (Part 22): 31, 302 cases; Person data (from flap, part 2404): 104, 153 cases; Worker (domestic) data (from part 4): 2, 701.

... The legislative agenda in most parliamentary systems is controlled tightly by the government and bills offered by individual members of parliament have low rates of success. Yet, MPs do seek to present (private) members’ bills even where the rate of adoption is very low. We argue that members’ bills serve as an electoral connection but also as an opportunity for MPs to signal competence to their co-partisans. To demonstrate the presence of an electoral connection we take advantage of the random selection of private members’ bills in the New Zealand House of Representatives and show that survey respondents approve more of electorate MPs whose bills were drawn on the ballot. In addition, we show that MPs respond to the incentives created by the voters and parties’ willingness to reward legislative effort and, consequently, that electorally vulnerable legislators are more likely to place members’ bills on the ballot.

... To see if attitudes are changing about the potential for using one's home to cover living expenses in retirement, the Center for Retirement Research commissioned a survey that examined the house as a potential source of retirement income. Harris Interactive® conducted the study online within the United States between January 24 and February 2, 2007 among 2,673 adults (aged 50-65). Figures for age, sex, race, education, household income, and region were weighted where necessary to bring them into line with their actual proportions in the population. Propensity score weighting was also used to adjust for respondents’ propensity to be online. The questionnaire, results, and raw data from both surveys are available.

... Transparency of research is a large concern in political science, and the practice of publishing links to datasets and other online resources is one of the main methods by which political scientists promote transparency. But the method cannot work if the links don’t, and very often, they don’t. We show that most of the URLs ever published in the American Political Science Review no longer work as intended. The problem is severe in recent as well as in older articles; for example, more than one-fourth of links published in the APSR in 2013 were broken by the end of 2014. We conclude that “reference rot” limits the transparency and reproducibility of political science research. We also describe practices that scholars can adopt to combat the problem: when possible, they should archive data in trustworthy repositories, use links that incorporate persistent digital identifiers, and create archival versions of the webpages to which they link.
