title: Instagram political preferences data donation dataset
title: Self-reported political preferences in combination with donated instagram data describing the participants activity on Instagram

description: These data were collected in spring 2025 from participants in the Ipsos panel in the Netherlands. Participants were invited to join a data donation study that involved the donating some of their Instagram data in addition to completing a questionnaire. The questionnaire data includes: 1) background characteristics of the participants 2) political preference 3) media usage 4) life satisfaction 5) trust in the government. The donated Instagram data consists of: 1) lists of Instagram creators whose content the participant had interacted with during the four months prior to requesting the data from Instagram. See readme.txt for the complete codebook of the questionnaire data and a description of the donated Instagram data. Of the 1,103 participants who expressed willingness to participate, 481 ultimately donated their Instagram data (see the readme.txt for what parts exactly). The primary objective of collecting this dataset was to test a federated learning approach for data donation.

title: Abiotic stress maps for rice (STRASA): Maps (kmz) for Africa with probability of presence of a saline/sodic soil overlaid with crop maps to identify areas with lots of salinity/sodicity AND lots of rice

description: This dataset is produced for the STRASA project in which breeders are developing varieties tolerant to salinity/sodicity. The intended use is that tolerant varieties can be sent to places with high risk of salinity/sodicity. This "salinity/sodicity" map was combined with three crop maps (GAEZv3, MIRCA2000,SPAM2005) to identify countries and hotspots, that is sites with lots of rice and lots of salinity.

title: Generation of High-Power, Reversed-Cherenkov Wakefield Radiation in a Metamaterial Structure

description: We present the ﬁrst demonstration of high-power, reversed Cherenkov wakeﬁeld radiation by electron bunches passing through a metamaterial structure. The structure supports a fundamental TM-like mode with a negative group velocity leading to reversed Cherenkov radiation, which was clearly veriﬁed in the experiments. Single 45 nC electron bunches of 65 MeV traversing the structure generated up to 25 MW in 2 ns pulses at 11.4 GHz, in excellent agreement with theory. Two bunches of 85 nC with appropriate temporal spacing generated up to 80 MW by coherent wakeﬁeld superposition, the highest RF power that metamaterial structures ever experienced without damage. These results demonstrate the unique features of metamaterial structures that are very attractive for future high-gradient, wakeﬁeld accelerators, including two-beam and collinear accelerators. Advantages include the high shunt impedance for high power generation and high gradient acceleration; the simple and rugged structure; and a large parameter space for optimization.

title: The Costs of Conflict and Support for the Use of Force: Accounting for Information Equivalence in Survey Experiments

description: How do the costs of conflict influence public support for the use of force? Existing research finds that weapons that eliminate the possibility of military casualties, such as drones, increase popular support for engaging in conflict. We argue that this effect may be overstated because the choice of weapons technology is endogenous to conflict. Leaders may select to use drones in conflicts where the risk of harm to ground forces is especially high. To address this, we replicate and extend the research design in Walsh and Schulzke (2018) across three survey experiments. The key innovation in our experiments is that subjects are led to believe that the choice of attack type—drones or ground troops—is determined by weather conditions rather than strategic considerations. We find that support for military action does not differ across treatments in which subjects are told that the attack involves drone strikes or ground troops.

title: Haiti (2009): HIV/ AIDS Focus for Qualitative Segmentation: Clients of Female Commercial Sex Workers

description: PSI/Haiti has been working with female CSWs for the past three years on a project called Condomania. It is a community-based education project focusing on female CSWs working in the various bars and bordellos in Port-au-Prince and other large provincial cities. During these Condomania activities, the clients of the female CSWs are often present. The clients have questioned why PSI-Haiti does not have any programs directed towards them. This stated need for client-specific programs has motivated PSI/Haiti to conduct a FoQus for Qualitative Segmentation study in order to gather information to help develop client-specific programs and communications materials. The study was conducted in four villages in Haiti: Port-au-Prince, Carrefour, Delmas, and Petion-Ville. 24 clients of CSWs were selected to participate in the study, which used individual photonarrative interviews to collect information from the participants.

title: 2015 Africa-wide Breeding Task Force Trials for Rainfed Lowland - PET

description: In 2010, the Africa-wide Rice Breeding Task Force was launched by 
AfricaRice involving National Agricultural Research System (NARS) from 
about 30 countries. The objectives of the network are to evaluate the 
stability of traits incorporated in breeding processes and to identify 
varieties best fit to growth conditions in target regions and to markets. 
The Task Force also accumulates data on performance of new elite lines, 
thereby facilitating varietal release procedures. Furthermore, by 
exposing breeders from NARS and farmers to these elite lines during the 
testing phase, dissemination will be facilitated. 

The activities conducted by the Task Force consists of a series of 
consecutive trials. Promising breeding lines developed by AfricaRice or 
by national and international partners, such as IRRI, CIAT and the NARS 
are nominated for evaluation in one or several rice cultivation 
environments: rainfed lowland, irrigated lowland, rainfed upland, high 
elevation and mangrove. All nominated lines should be fixed and 
accompanied by supporting data on traits incorporated during the breeding 
process and with information on yield performance. These characteristics 
are checked at AfricaRice before incorporation into the network. 

The first phase (MET, Multi-Environment Testing) consists of an initial 
evaluation of about 100 lines selected from the nominated lines. 
Each national partner evaluates these lines at sites in his/her country. 
Such sites may be at an experimental station under optimal management 
to evaluate yield potential, or may be ‘hot spots’ to check the 
performance of the nominations in a stressed growth environment. 
Trials are replicated three times and include at least a common 
and a local check.

The second phase (PET,Participatory Evaluation Trial) serves to 
evaluate and confirm the performance of the selected lines. These lines 
are cultivated using the same experimental design with 3 replications. 
An important feature of PET is that farmer and other stakeholders 
such as miller and traders are invited to participate in varietal 
selection and their opinion on the performance of all entries 
(i.e. participatory varietal selection, PVS) collected. Based on the 
data collected, observations by the breeders and the opinion of 
stakeholder groups, NARS partners select up to 10 lines.

Further, NARS evaluated these lines in at least three sites per country and during one or more growing seasons, depending on varietal release requirements. All stakeholders are again invited to get acquainted with the new lines and voice their opinion to help select lines for further advancement. Among the 10 lines, farmers are invited to select three lines and cultivate these in their own fields, together with a common check and their own variety.

description: Reproducibility in cardiac MRI research is a pervasive issue across the field, which impacts the translational pathway. Given the relative infancy of research within 4D-flow cardiovascular magnetic resonance (CMR) imaging and the accepted potential for this imaging technique to propel our understanding of cardiovascular disease, it becomes important to establish repeatability of the various aspects of the techniques. This dataset includes the left ventricular blood flow kinetic energy parameters of twenty patients void of any known cardiovascular disease, collected from two sites in the United Kingdom and the Netherlands. Here we present data from the inter-observer and intra-observer reproducibility analyses following 4D-flow CMR.

title: Replication data for: Clearing the Hurdle: Border Settlement and Rivalry Processes

description: Why do interstate rivalries end? In pursuit of this question, we advance a territorial theory of rivalry to account for termination, which bridges the limited theoretical work on rivalry termination, the logic of commitment problems, and recent research associated with the territorial peace. We argue that unsettled borders are caused by an underlying commitment problem that contributes to the formation and perpetuation of rivalry. Ending the rivalry (by settling the borders) requires overcoming this fundamental commitment problem. We suggest that the signing of an international border agreement therefore represents a tangible indicator that states have overcome this commitment problem. After such agreements, we therefore expect rivalry termination to hasten and the rivalries that persist to experience fewer, shorter, and less severe conflict episodes. Empirical analysis of rivalries during the period 1816-2001 confirm these expectations. Such findings offer support to our unified (territorial) theory of rivalry and suggest that those seeking to manage rivalries might first focus upon unsettled borders as they attempt to create more peaceful interstate relations.

title: The corrected raw data

description: Herein is the raw data used for all subsequent analyses. There is one data file, and two programs. One program combines multiple data files into a single dataset, while another is used to search for errors in the data.

The most common errors are of two types.
1) Repeat waveforms. NP-C-C-D is not allowed. However, the program does not know if the consecutive pathway behaviors (waveform C) are the same behavior recorded twice, or if partway through the behavior it was stopped and then continued. 
2) Invalid transitions. NP-G, NP-D, NP-E1, NP-E2, C-E1, C-E2, G-D, G-E1, G-E2, D-G, D-E2, E1-G, and E2-G are not allowed. It might be possible to have E1-D, and E2-D but these have never been observed and should be carefully examined if found. The errors are mostly self-evident. The first example NP-G would mean that the insect did not have stylets inserted into the plant and then immediately started ingesting xylem. The sample rate of 1/100 second is fast enough that it is not possible for the insect to move anywhere without being detected.

It is assumed that these steps were performed successfully in all subsequent steps in the analysis of these data. There is no further error checking.
