Resonances in the asteroid and trans-Neptunian belts: a brief review
Mean motion resonances play a fundamental role in the dynamics of the small
bodies of the Solar System. The last decades of the 20th century gave us a
detailed description of the dynamics as well as the process of capture of small
bodies in coplanar or small inclination resonant orbits. More recently,
semianalytical or numerical methods allowed us to explore the behavior of
resonant motions for arbitrary inclination orbits. The emerging dynamics is
very rich, including large orbital changes due to secular effects inside mean
motion resonances. The process of capture in highly inclined or retrograde
resonant orbits was addressed showing that the capture in retrograde resonances
is more efficient than in direct ones. A new terminology appeared in order to
characterize the properties of the resonances. Numerical explorations in the
transneptunian region showed the relevance and the particular dynamics of the
exterior resonances with Neptune which can account for some of the known high
perihelion orbits in the scattered disk. Moreover, several asteroids evolving
in resonance with planets other than Jupiter or Neptune were found and a large
number of asteroids in three-body resonances were identified.Comment: Asteroids, Comets, Meteors 2017 meetin

La perspectiva intercultural en los libros para la enseñanza de lenguas modernas.Un enfoque histórico
This paper analyses the pedagogical and practical approaches to the teaching of culture which were used in a range of popular French, Spanish, Italian and German grammars and text-books published in the XIX century in Europe and America. Series such as Ollendorff´s and Hossfeld´s show an understanding of cultural differences associated to the language of study as well as a practical consideration towards their students´needs which are reflected in the selection of linguistic material as well as in the creation of strategies for language and cultural learning
A note on graded hypersurface singularities
For a weighted quasihomogeneous two dimensional hypersurface singularity, we
define a smoothing with unipotent monodromy and an isolated graded normal
singularity. We study the natural weighted blow up of both the smoothing and
the surface. In particular, we describe our construction for the
quasihomogeneous singularities of type I, the 14 unimodal exceptional
singularities and we relate it to their stable replacement.Comment: 19 pages, 4 figures. New section on stable replacement of Unimodal

A framework for regulating microfinance institutions : the experience in Ghana and the Philippines
An earlier Policy Research Working Paper (Hennie van Greuning, Joselito Gallardo, and Bikki Randhawa,"A Framework for Regulating Microfinance Institutions,"WPS 2061, February 1999) presented a regulatory framework that identifies thresholds in financial intermediation activities that trigger a requirement for a microfinance institution to satisfy external or mandatory guidelines-a tiered approach to regulation and prudential supervision. The model focuses on risk-taking activities of microfinance institutions that must be managed and prudentially regulated. The author reports on the results of the field testing and assessment of the tiered approach, focusing on the experience of Ghana and the Philippines. The two countries both have a wide range of informal, semi-formal, and formal institutions providing financial services to the poor, but differ in how they regulate financial intermediation activities by microfinance providers. In his assessment and a comparative analysis, the author focuses on key issues in the regulatory and supervisory environment for microfinance-and in the legal system and judicial processes-being addressed by government authorities and microfinance stakeholders in both countries. He gives particular attention to the thresholds at which intermediation activities become subject to prudential regulation and regulatory standards for capitalization and capital adequacy, asset quality and provisioning for nonperforming loans, and liquidity management. seeks to identify the key elements and characteristics of the microfinance regulatory experience of Ghana and the Philippines and to draw the lessons that may be useful for other countries interested in establishing a regulatory environmentconducive to the development of sustainable microfinance institutions. The experience of Ghana and the Philippines shows that a transparent, inclusive regulatory framework is indispensable for enabling microfinance institutions to maintain market specialization and to pursue institutional development that leads to sustainability. Clear pathways for institutional transformation facilitate the integration of microfinance institutions into the formal financial system.Payment Systems&Infrastructure,Banks&Banking Reform,Rural Finance,Financial Intermediation,Decentralization,Banks&Banking Reform,Rural Finance,Financial Intermediation,Governance Indicators,Poverty Assessment
The Relativistic Factor in the Orbital Dynamics of Point Masses
There is a growing population of relativistically relevant minor bodies in
the Solar System and a growing population of massive extrasolar planets with
orbits very close to the central star where relativistic effects should have
some signature. Our purpose is to review how general relativity affects the
orbital dynamics of the planetary systems and to define a suitable relativistic
correction for Solar System orbital studies when only point masses are
considered. Using relativistic formulae for the N body problem suited for a
planetary system given in the literature we present a series of numerical
orbital integrations designed to test the relevance of the effects due to the
general theory of relativity in the case of our Solar System. Comparison
between different algorithms for accounting for the relativistic corrections
are performed. Relativistic effects generated by the Sun or by the central star
are the most relevant ones and produce evident modifications in the secular
dynamics of the inner Solar System. The Kozai mechanism, for example, is
modified due to the relativistic effects on the argument of the perihelion.
Relativistic effects generated by planets instead are of very low relevance but
detectable in numerical simulations
