  • We use a randomized controlled trial to study the response of poor households in rural Kenya to large, unconditional cash transfers from the NGO GiveDirectly. The transfers differ from other programs in that they are explicitly unconditional, large, and concentrated in time. We randomized at both the village and household levels; further, within the treatment group, we randomized recipient gender (wife vs. husband), transfer timing (lump-sum transfer vs. monthly installments), and transfer magnitude (USD 404 PPP vs. USD 1,525 PPP). We find a strong consumption response to transfers, with an increase in household monthly consumption from USD 158 PPP to USD 193 PPP nine months after the transfer began. Transfer recipients experience large increases in psychological wellbeing. We find no overall effect on levels of the stress hormone cortisol, although there are differences across some subgroups. Monthly transfers are more likely than lump-sum transfers to improve food security, while lump-sum transfers are more likely to be spent on durables, suggesting that households face savings and credit constraints. Together, these results suggest that unconditional cash transfers have significant impacts on economic outcomes and psychological wellbeing.

  • 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.

  • Subnational poverty headcount ratios were derived from 66 nationally representative household surveys and population census information conducted in various years around 2008 for 26 countries. Our poverty calculations are based on the comparison between the household per-capita consumption expenditure (a synthetic indicator expressing the money-metric welfare utility level) and the $1.90 and $3.10/day poverty lines expressed in international equivalent purchasing power parity (PPP) dollars in 2011. Poverty headcount with standard deviation, gap, severity, and Gini index are also provided.

  • HistPat provides the geography of historical patents granted by the United States Patent and Trademark Office (USPTO) from 1790 to 1975. This historical dataset is constructed using digitalized records of original patent documents that are publicly available. HistPat can be used in different disciplines ranging from geography, economics, history, network science, and science and technology studies. Additionally, it can easily be merged with post-1975 USPTO digital patent data to extend it until today.

  • This dataset includes summary physiology and MRI data used in a publication identifying sex differences in insular organization to an autonomic challenge, the Valsalva maneuver. The protocol consistent of healthy participants performing a series of four 18-second Valsalva maneuvers one minute part, with baseline and recovery periods. Continues fMRI whole-brain scans were collected at 2 s intervals, and concurrent pulse oximetry data were acquired. The data include the SaO2 levels and continuous heart rate derived from the pleth waveform. The files include pdf and MATLAB figures, and tables and results from a SAS dataset with statistical results from RMANOVA (see 10.12688/f1000research.8252.1 for method). The MRI data include summary T1 files after DARTEL normalization in SPM12. The fMRI data include the preprocessing whole-brain images (motion-corrected, coregistered to T1, spatially normalized using T1 DARTEL parameters, smoothed 8mm FWHM), and VOI-specific timetrends, figures and RMANOVA statistics and graphs. Full details are included in the publication (10.3389/fneur.2016.00087).

  • This paper tests the effects on the take-up of a preventative health product of two interventions based on behavioral models derived from psychology: varying the framing of the perceived benefits; and having people verbally commit to purchase the product. I find that none of these interventions had a significant effect (whether economically or statistically) on take-up, and that the gender of the household member targeted was also irrelevant. In contrast, I find that take-up is sensitive to price, as in Cohen and Dupas (2008), and is correlated with indicators of household’s wealth.

  • Rare-earth elements are an attractive class of dopant elements, as they give easily trivalent cations that possibly altering the structure and other properties of the parent nanoparticles and creating multifunctional materials because of their f-electronic configurations. Herein, experimental evidence has been given for a better understanding of the factors that dictate the interactions of La doping on the structure and optical properties of iron oxide nanoparticles. For that, lanthanum doped hematite (α-Fe2O3) nanoparticles were prepared by a facile solution method using iron (III) chloride (FeCl3) as starting precursor and sodium hydroxide (NaOH) as reducing agent without templates at low temperature. As-prepared powders were subsequently calcined in air for 3 hr at 800 ºC. X-ray diffraction (XRD) technique was used to study the nanocrystal formation of α-Fe2O3 and Fourier Transform Raman (FT-Raman) spectral information identified the chemical bond structure of the nanoparticles. Morphology study of the nanoparticles was identified using Scanning Electron Microscope (SEM) and the incorporated La content was recognized from the Energy Dispersive X-ray Spectroscopy (EDS) analysis. The optical absorption spectrum was recorded in the wavelength range of 200-2000 nm and the optical parameters such as absorption coefficient and optical band gap energy of pure and doped Fe2O3 nanoparticles were determined. Obtained results are interpreted by considering the impregnation of trivalent La cations that replaced Fe cations of the host structure.
