Toward a Real Simple Taxonomy: Bridging Learners and Content to Create New Value at LearnPhilanthropy

LearnPhilanthropy is bringing together the wealth of research, resources and ideas on good practice from sources across the sector: Imagine a farmer's market providing fresh products from a variety of producers, all in one place, as well as a gathering place where practitioners of all kinds can come together to exchange "recipes" and learning perspectives. A general purpose taxonomy is needed to help make these resources more widely accessible. Yet we've found that a general-purpose taxonomy on grantmaker learning just plain doesn't exist. Our research to date -- conducted in partnership with our Planning Committee, Content Partners, workgroup members and others in the field -- has turned up taxonomies mostly for specific audiences or grantmaker types.For this reason, LearnPhilanthropy developed a general-purpose taxonomy, with an iterative and highly collaborative approach -- more user-generated folksonomy than the traditionally hierarchical taxonomy -- and broad review at each iteration stage. We see this Real Simple Taxonomy as a living document, and encourage ongoing co-creation and co-ownership within the LearnPhilanthropy community

Purchasing Power Parity and Real Exchange Rate in Japan

This paper examines the validity of both the short-run and long-run purchasing power parity (PPP) hypotheses in Japan using two estimation methods, namely, a unit root test and an Autoregressive Distributed Lag (ARDL) cointegration test. Some important findings are obtained from our analysis. The first test reveals the mean reversion of real exchange rate (RER) in the long-run. On the other hand, from the second test, we found that there is a strongly robust long-run PPP relationship but no significant short-run PPP relationship. Furthermore, unlike the previous literature, this paper confirms the stability of the estimated results by CUSUM and CUSUMQ tests. Overall, the results suggest that PPP hypothesis in Japan strongly holds for the long-run while not for the short-run.PPP; Real Exchange Rate; Unit Root; ARDL to cointegration

The Long-Run of Purchasing Power Parity: The Case of Japan

This paper examines the validity of both the short-run and long-run purchasing power parity (PPP) hypotheses in the case of the Yen-Dollar exchange rate using two estimation methods, namely, a unit root test and an Autoregressive Distributed Lag (ARDL) cointegration test. Some important findings are obtained from our analysis. The first test reveals the mean reversion of real exchange rate (RER) in the long-run. From the second test, we found that there is a strongly robust long-run PPP relationship but only weakly significant short-run PPP relationship. Furthermore, unlike the previous literature, we use CUSUM and CUSUMSQ stability tests and rolling estimations to deal with the problems of structural breaks and power of the test respectively. Overall, the results suggest that PPP hypothesis in the case of Yen-Dollar exchange rate strongly holds in the long-run but weakly in the short-run. Finally, our results suggest that a minimum of 30 years of sample be a benchmark required for long-run PPP to hold for the case of Japan.PPP, Real Exchange Rate, Unit Root, ARDL to cointegration

The Impact of Childhood Health on Adult Educational Attainment: Evidence from Modern Mandatory School Vaccination Laws

This paper examines the impact of post-neonatal childhood health on adult educational attainment using evidence from mandatory school vaccination laws in the U.S. After the development of a number of key vaccines, states began to require proof of immunization against certain infectious diseases for children entering school. I exploit the staggered implementation of the laws across states to identify both the short-run impacts on child health and long-term effects on educational attainment. First, I show that the mandatory school vaccination laws were effective in reducing the incidence rates of the targeted diseases. Next, I find sizable and positive effects on educational outcomes as measured by high school completion and years of schooling. The effect on educational attainment is twice as large for non-whites relative to whites.school vaccinations, morbidity, health, educational attainment

Optical Signatures of Non-Markovian Behaviour in Open Quantum Systems

We derive an extension to the quantum regression theorem which facilitates the calculation of two-time correlation functions and emission spectra for systems undergoing non-Markovian evolution. The derivation exploits projection operator techniques, with which we obtain explicit equations of motion for the correlation functions, making only a second order expansion in the system--environment coupling strength, and invoking the Born approximation at a fixed initial time. The results are used to investigate a driven semiconductor quantum dot coupled to an acoustic phonon bath, where we find the non-Markovian nature of the dynamics has observable signatures in the form of phonon sidebands in the resonance fluorescence emission spectrum. Furthermore, we use recently developed non-Markovianity measures to demonstrate an associated flow of information from the phonon bath back into the quantum dot exciton system.Comment: Comments welcom
