How To Make A Pie: Reproducible Research for Empirical Economics & Econometrics

Empirical economics and econometrics (EEE) research now relies primarily on the application of code to datasets. Handling the workflow linking datasets, programs, results and finally manuscript(s) is essential if one wish to reproduce results, which is now increasingly required by journals and institutions. We underline here the importance of “reproducible research” in EEE and suggest three simple principles to follow. We illustrate these principles with good habits and tools, with particular focus on their implementation in most popular software and languages in applied economics

Исследовательская деятельность эколого-биологической направленности в НОУ "Эврика" - эффективное средство профессиональной ориентации учащихся

В статье научно-исследовательская деятельность эколого-биологической направленности старшеклассников НОУ "Эврика" г. Нижнего Новгорода рассматривается как одна из значимых инновационных форм профессионального самоопределения. Материалом исследования послужил анализ программ конференции городского научного общества учащихся "Эврика" и судьбы выпускников данного общества. Отмечена тенденция роста популярности эколого-биологических исследований среди старшеклассников г. Нижнего Новгорода и успешное вхождение в профессию выпускников научного общества учащихся.In the article, the research activity of the ecology and biology of senior pupils of the scientific society of the pupils "Eureka" in Nizhny Novgorod is considered as one of the significant innovative forms of professional self-determination. The material of the study was the analysis of the programs of the conference of the city scientific society of the students "Eureka" and the fate of the graduates of this society. The tendency of growth of popularity of ecological and biological researches among senior pupils of Nizhny Novgorod and successful entry into the profession of graduates of the scientific society of students is noted

Australian clinical practice guidelines for the diagnosis and management of Barrett's esophagus and early esophageal adenocarcinoma

Author version made available following 12 month embargo from date of publication according to publisher copyright policy.Barrett's esophagus (BE), a common condition, is the only known precursor to esophageal adenocarcinoma (EAC). There is uncertainty about the best way to manage BE as most people with BE never develop EAC and most patients diagnosed with EAC have no preceding diagnosis of BE. Moreover, there have been recent advances in knowledge and practice about the management of BE and early EAC. To aid clinical decision making in this rapidly moving field, Cancer Council Australia convened an expert working party to identify pertinent clinical questions. The questions covered a wide range of topics including endoscopic and histological definitions of BE and early EAC; prevalence, incidence, natural history, and risk factors for BE; and methods for managing BE and early EAC. The latter considered modification of lifestyle factors; screening and surveillance strategies; and medical, endoscopic, and surgical interventions. To answer each question, the working party systematically reviewed the literature and developed a set of recommendations through consensus. Evidence underpinning each recommendation was rated according to quality and applicability

Large area self-powered gamma ray detector. Phase 2, Development of a source position monitor for use on industrial radiographic units

The purpose of this research was to develop a large area self-powered gamma detector (LASPGD) capable of detecting the movement of sealed radiation sources into and out of industrial radiographic units and to construct a prototype source position monitor (SPM) for these units utilizing the LASPGD. Prototype isotropic and directional LASPGDs, with solid and inert gas dielectrics, were developed and extensively tested using calibrated gamma sources (i.e., Cs-137, and Co-60). The sensitivities of the isotropic detectors, with inert gas dielectrics, were found to be approximately a factor of ten greater than those measured for the solid dielectric LASPGDs. Directionally sensitive self-powered detectors were found to exhibit a forward-to-back hemispherical sensitivity ratio of approximately 2 to 1. Industrial radiographic units containing Ir-192 sources with different activities were used to test the performance of the SPM. The SPM, which utilized a gas dielectric LASPGD, performed as designed. That is, the current generated in the LASPGD was converted to a voltage, amplified and used to control the on/off state of an incandescent lamp. The incandescent lamp, which functions as the source/out warning indicator, flashes at a rate of one flash per second when the source is in use (i.e. out of its shield)

Potential adoption of GM rapeseed in France, effects on revenues of farmers and upstream companies : an ex ante evaluation

Diffusion du document : INRA Unité d'Economie et Sociologie rurales 4 Allée Adolphe Bobierre CS 61103 35011 Rennes cedex (FRA)Ce document présente une investigation empirique de l'adoption potentielle de colza génétiquement modifié (OGM) tolérant à un herbicide en France. L'objectif est d'étudier ex ante l'impact potentiel de la diffusion de cette innovation en termes de taux d'adoption, de gains potentiels liés à l'adoption, et de distribution de ces gains potentiels entre agriculteurs et industries d'amont. Les auteurs utilisent des données d'enquête sur les pratiques actuelles de désherbage en France, pour calculer la distribution des coûts en herbicide dans le cas de cultures conventionnelles de colza (c'est-à-dire non OGM). Ensuite, en utilisant les résultats d'études techniques sur les essais OGM en France, ils calculent un coût prévisionnel en herbicide avec une variété OGM. Ils étudient alors les taux d'adoption, les gains et pertes potentiels des agriculteurs (adopteurs et non adopteurs) et des industries d'amont (fournisseurs des herbicides conventionnels, de l'herbicide total auquel la plante OGM est résistante, de la semence OGM), selon le prix de la semence OGM, le taux de marge sur les ventes d'herbicides conventionnels et le prix des herbicides conventionnels
