Equilibrium Structures of Pyrazine, s-Triazine, and s-Tetrazine
Jürgen Breidung,Walter Thiel +1 more
TL;DR: In recent years, accurate equilibrium structures have been determined for pyridine, pyridazine, and pyrimidine for the structurally related molecules py... as discussed by the authors, and they have been reported accurate re-structures for other related molecules.
Decomposition of multihomogeneous polynomials: minimal number of variables
TL;DR: In this article, the ridge and directrix invariants of homogeneous ideals are generalized to multihomogeneous ideals and algorithms to compute these invariants are presented. But their complexity depends on the number of blocks of variables, number of variables in each block and the degree of the polynomials spanning the ideal.
Dissertation
Using Bayesian techniques with item response theory to analyze mathematics tests
TL;DR: This work compares the use of free software (Item Response Theory Command Language) to generally accepted commercial software (Xcalibre) in the analysis of College Algebra final exams and uses Item Response Theory (IRT) models to determine the instrument's reliability at various points along the student ability spectrum.

Assessment of Ore Deposit Settings
TL;DR: In this paper, the authors discuss problems faced by field geologists in assessing intensely deformed metavolcanic sequences and recognition of unconformities and metaevaporites in ancient terrains.
Journal ArticleDOI
Molecules as diagnostic tools in the interstellar medium
TL;DR: In this article, the authors focused on collisional excitation rates of molecules relevant to the interstellar medium and discussed the use of accurate ab initio potential energy surfaces, which could lead to important changes in the interpretation of molecular emission emerging from molecular clouds.

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.
