title: Presence and Quantification of Microplastic in Urban Tap-Water

description: Plastic pollution is a rapidly growing environmental and human health crisis, with no sign of improvement. Since 2012 the number of studies on plastic pollution has quadrupled, and macro to nano-size plastics have been documented even in the planet's remote biomes. Studies have shown contamination by microplastics (MPs) in various types of food consumed by humans, including seafood, honey, sugar, salt, tap-water and bottled water and beer. The study's objective was to detect the possible contamination by MPs in drinking water samples collected from the two main residential and commercial areas of Brasília. A total of 32 samples of tap water were collected, 16 samples in the south zone, and 16 samples in the north zone of the city (respectively, South Wing and North Wing). Samples were processed and transferred to the Sedgewick-Rafter counting cell chamber. The presence of MPs particles was analysed using a Nikon Eclipse fluorescence microscope. MPs were found in 100% of the samples. The mean MPs per 500 ml found in the South Wing area was 97, while the mean number of particles in the North Wing area was 219. The study results reveal a disturbing amount of MP particles in Brasilia's tap-water. This surprising number of particles in tap-water is especially concerning considering that tap-water is not the only source of MPs to which people are exposed. The cumulative and toxicological effect of this chronic exposure is alarming.

title: Replication Data for: Submerged for Some? Government Visibility, Race, and American Political Trust

description: Scholarship concerning American government visibility has focused on the state’s growing submergence, yet these accounts contrast with race and ethnic politics research focusing on the American state’s conspicuousness in the lives of people of color. Attending to this disconnect, this paper asks how government visibility varies across racial groups. Combining interviews and quantitative analysis within a policy feedback framework, I argue that five public policy trends have created a racial split in the American state’s visibility. For whites, submerged state policies have grown alongside the rising visibility of racialized poverty policies and taxation. As a result, whites are less aware of how government benefits them and more aware of how government uses tax dollars to fund programs perceived as solely benefitting racial others. For people of color, the decline of civil rights legislation has contrasted with criminal legal policies that have made the criminal legal system a uniquely visible manifestation of government in their lives. To demonstrate the political importance of this racial divide, I uncover a racial heterogeneity in people’s political trust attachments, wherein white trust is connected to welfare attitudes, while trust among people of color is associated with feelings about the police.

title: Replication Data for: Model Uncertainty, Political Contestation, and Public Trust in Science: Evidence from the Covid Pandemic

description: Policymakers rely on scientific models, but the inherent uncertainty of underlying assumptions and data renders models susceptible to political contestation in ways that threaten public confidence in the models and the policies they inform. We investigate the politics and policy implications of Covid models predicting the virus’ course. We conduct five experiments that probe how the partisan identity of the cue-giver and the substance of the cue – particularly how it frames uncertainty – affect public trust in science and support for science-based policy. Democratic criticism undermines trust more than criticism from Republicans, even when it was not the intention of the signaling elite. Emphasizing and exploiting uncertainty in projections can erode public trust. Downplaying uncertainty and exaggerating the dire consequences of failing to heed model projections can raise support in the short-term but backfires when projections prove wrong. Transparently acknowledging and contextualizing uncertainty avoids these backfire effects without threatening public trust.

title: (Non-) Involvement in Terrorist Violence Dataset (NITV)

description: This dataset describes 206 individuals who radicalised to extremism. Exactly half of the sample (N=103) radicalised to right-wing extremism, and half to jihadism. The sample is also split 50/50 in terms of the outcome of these radicalization processes: 103 individuals became involved in the planning, preparation or execution of terrorist attacks, the other 103 did not. The purpose of our dataset was to gain insights into what variables influence these outcome differences. To that end, we used a codebook to look at structural, group and individual-level variables theorised to influence the onset and outcome of radicalization processes. The dataset describes individuals from Europe and North-America (Canada / US) with an average date of birth of 1980.

Data on our population was gathered from a range of sources, such as secondary literature (e.g. academic publications, think-tank reports), journalistic accounts, court records, (auto)biographies and, where possible, privileged information drawn from semi-structured interviews and material provided by the Dutch public prosecution service. To ensure their privacy and security, all personally-identifying information has been rigorously removed. This means that no data on names, exact dates of birth, places of residence etc. is included in the dataset. All interviewees were asked to sign consent forms and the project went through formal ethics approval by Leiden University's Faculty of Governance and Global Affairs (FGGA) Ethics Committee (ref: 2019-012-ISGA-Schuurman) before it commenced.

title: Salt Prints Survey Data

description: Salt prints represent the first negative-to-positive photographic technique. Introduced by Englishman William Henry Fox Talbot in 1839, it is the process from which most nineteenth- and twentieth-century photographic formats were derived. Collections of salt prints found in libraries, archives, and museums at Harvard University include some of the earliest photographic images created, and they represent a seminal chapter in the history of photography. Together, these holdings reveal technological developments in the medium and pioneering uses of photography across the sciences and humanities. Please visit &lt;a href="https://projects.iq.harvard.edu/saltprintsatharvard"&gt;https://projects.iq.harvard.edu/saltprintsatharvard&lt;/a&gt; to learn more about the full project and access digital images.

title: Replication Data for: Tree-Based Models for Political Science Data

description: Political scientists often find themselves analyzing datasets with a large number of observations, a large number of variables, or both. Yet, traditional statistical techniques fail to take full advantage of the opportunities inherent in ``big data'' as they are too rigid to recover nonlinearities and do not facilitate the easy exploration of interactions in high-dimensional datasets. In this paper, we introduce a family of tree-based nonparametric techniques that may, in some circumstances, be more appropriate than traditional methods for confronting these data challenges. In particular, tree models are very effective for detecting nonlinearities and interactions, even in datasets with many (potentially irrelevant) covariates. We introduce the basic logic of tree-based models, provide an overview of the most prominent methods in the literature, and conduct three analyses that illustrate how the methods can be implemented while highlighting both their advantages and limitations.

title: Replication Data for: The Arc of Modernization: Economic Structure, Materialism, and the Onset of Civil Conflict

description: The onset of intrastate conflict has two requisite conditions: that prospective insurgents have an incentive to rebel, and that the state lacks the capacity to deter such a rebellion. We outline a simple rationalist argument grounded in gains from economic growth (to both individual income and state revenues) to argue that modernization has the potential to affect the likelihood of civil conflict through both of these conditions. The shift away from a rent-seeking economy affects opportunity costs for rebellion by increasing the cost of recruitment, broadening the time horizon for gain, and decreasing looting possibilities. On the state side, modernization increases state military, economic, and institutional capacity, allowing governments to deter rebellion. We construct an index of modernization from World Bank data and apply a strategic model to explore the effect of modernization on both states and rebels simultaneously. We find that the modernization process describes an arc that may increase the likelihood of unrest in the early stages, but has long-term stabilizing effects.
