Sea-level reconstruction for Turonian sediments from Tanzania based on integration of sedimentology, microfacies, geochemistry and micropaleontology
TL;DR: In this article, the authors reconstruct relative sea-level changes based on sequence stratigraphy and integration of sedimentology, microfacies, geochemistry, and micropaleontology.

TL;DR: T theoretical calculations using the density functional theory with the B3LYP and MPW1B95 energy functionals and the 6-311G** and cc-pVTZ basis sets have been performed for these molecules and the corresponding one-ring species to obtain the most stable geometries and to access their energetic stabilities.

The crinoid Marsupites in the Upper Cretaceous Nanaimo Group, British Columbia: Resolution of the Santonian–Campanian boundary in the North Pacific Province
TL;DR: The presence of the crinoid genus Marsupites Mantell in Miller 1821, considered a marker of the Santonian-Campanian boundary at many places around the globe, has been collected recently from a number of localities of the Upper Cretaceous Nanaimo Group succession of southwestern British Columbia, including the species M.testudinarius and M.lamberti as discussed by the authors.
Journal ArticleDOI
The existence of superluminal particles is consistent with the kinematics of Einstein's special theory of relativity
TL;DR: Within an axiomatic framework of kinematics, it was shown in this article that the existence of faster than light particles is logically independent of Einstein's special theory of relativity.
Journal ArticleDOI
Generalization of Intrinsic Orbitals to Kramers-Paired Quaternion Spinors, Molecular Fragments, and Valence Virtual Spinors
TL;DR: This paper generalizes the intrinsic atomic and bonding orbitals to relativistic applications using complex and quaternion spinors, as well as to molecular fragments instead of atomic fragments only, and shows how localized valence virtual orbitals can be expressed on this intrinsic minimal basis.

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.
