From Oppel to Callomon (and beyond): building a high‐resolution ammonite‐based biochronology for the Jurassic System
TL;DR: Arkell et al. as discussed by the authors proposed a very modern looking global subdivision of a Jurassique "System" into a sequence of 10 etages, which were based on a basic biostratigraphical framework, but there were still some issues with its actual demonstrable applicability internationally.

Nuclear shieldings with the SSB-D functional.
TL;DR: The recently reported SSB-D functional is compared with its "parent" functionals, the KT2 functional that was designed specially for NMR applications and the coupled cluster CCSD(T) method and the best performance for the experimentally most-used elements ((1)H, (13)C) is obtained for the SSB -D and KT2 functionals.

Negative ions of nitroethane and its clusters
Sarah T. Stokes,Kit H. Bowen,Thomas Sommerfeld,Shaun G. Ard,Nasrin Mirsaleh-Kohan,Jeffrey D. Steill,Robert N. Compton +6 more
TL;DR: Valence and dipole-bound negative ions of the nitroethane (NE) molecule and its clusters are studied using photoelectron spectroscopy, Rydberg electron transfer techniques, and ab initio methods to suggest that NE clusters form only anions where the excess electron localizes on a single monomer.
Journal ArticleDOI
Evaluation of composite schemes for CCSDT(Q) calculations of interaction energies of noncovalent complexes
TL;DR: This work has examined the accuracy of composite schemes where CCSDT(Q) correction calculated in a smaller basis set is added to CCSD(T), C CSD[T] and CCS DT calculations and found that the differences between the studied schemes are small.
Book ChapterDOI
Construction of Machine Learned Force Fields with Quantum Chemical Accuracy: Applications and Chemical Insights
TL;DR: The hierarchical pathway from generating the dataset of reference calculations to the construction of the machine learning model, and the validation of the physics generated by the model are discussed, and empirical evidence that a higher level of theory generates a smoother PES is provided.

Impact Evaluation of a Conditional Cash Transfer Program: The Nicaraguan Red de Proteccion Social
John A. Maluccio,Rafael Flores +1 more
TL;DR: The impact evaluation of a conditional cash transfer program was performed by the Nicaraguan Red de Proteccion Social (RPS) as discussed by the authors, which evaluated the effectiveness of the program.
Journal ArticleDOI
The Case for Randomized Field Trials in Economic and Policy Research
TL;DR: The advantages and disadvantages of experiments in comparison with other research techniques are examined and the circumstances where randomized trials should be preferred over other methods are described.

An evaluation of the impact of progresa on pre-school child height
Jere R. Behrman,John Hoddinott +1 more
TL;DR: One of the major components of the PROGRESA program has been directed toward improving the nutritional status of small children in poor rural communities in Mexico as mentioned in this paper, which has been shown to have a substantial effect on lifetime productivities and earnings of currently small children.

Progressing through progresa: an impact assessment of a school subsidy experiment
TL;DR: The authors used a Markov schooling transition model applied to the experimental data to assess the impact of the educational subsidy program along several dimensions, including effects on initial ages of school entry, dropout rates, grade repetition rates, and school reentry rates.

A New Approach to Social Assistance: Latin America’s Experience with Conditional Cash Transfer Programs
TL;DR: Conditional cash transfer as discussed by the authors is a departure from more traditional approaches to social assistance, that represents an innovative, and increasingly popular channel for the delivery of social services that represents a demand-side complement to the supply of health, and education services.
