Controlled vocabularies and semantics in systems biology
The use of computational modeling to describe and analyze biological systems is at the heart of systems biology. Model structures, simulation descriptions and numerical results can be encoded in structured formats, but there is an increasing need to provide an additional semantic layer. Semantic information adds meaning to components of structured descriptions to help identify and interpret them unambiguously. Ontologies are one of the tools frequently used for this purpose. We describe here three ontologies created specifically to address the needs of the systems biology community. The Systems Biology Ontology (SBO) provides semantic information about the model components. The Kinetic Simulation Algorithm Ontology (KiSAO) supplies information about existing algorithms available for the simulation of systems biology models, their characterization and interrelationships. The Terminology for the Description of Dynamics (TEDDY) categorizes dynamical features of the simulation results and general systems behavior. The provision of semantic information extends a model's longevity and facilitates its reuse. It provides useful insight into the biology of modeled processes, and may be used to make informed decisions on subsequent simulation experiments

Knowledge Gaps and Misinformation About Birth Control Methods Persist in 2016
Beyond Birth Control: Family Planning and Women's Lives is a multiyear project examining the current state of access to contraception and how this access influences women's lives in the short and long term. Supported by the William and Flora Hewlett Foundation, the Urban Institute is using mixed research methods to answer two main questions under the project: how does expanded access to affordable contraception affect short- and long-term socioeconomic and health outcomes for women and their families, and what are the persistent barriers to contraceptive access and use, who faces these barriers, and how can these barriers be reduced? This brief is one of a series of Beyond Birth Control products that will provide new and timely information to influence policy debates and highlight areas where progress has been most challenging and where additional resources could most productively be directed
Growing Pains for the Los Angeles Healthy Kids Program: Findings From the Second Evaluation Case Study (Apr 2008)
Evaluates the program to provide health coverage to poor children ineligible for Medi-Cal or Healthy Families in terms of outreach, enrollment, and retention; benefits, service delivery, and access; financing and stability; and program improvement
Los Dibujos de trabajo de campo de la Escuela francesa de Geografía (Paul Vidal de La Blache y Pierre Deffontaines)
Els dibuixos de treball de camp a l'Escola francesa de Geografia
(Paul Vidal de la Blache i Pierre Deffontaines).
L'Escola francesa de Geografia ha desenvolupat el croquis de terreny i el dibuix de perfils,
blocs diagrames i croquis panoràmics com a eines eficaces per a l'anàlisi del paisatge
i particularment de les relacions entre les societats humanes i el seu entorn físic. Paul
Vidal de La Blache, precursor en aquest camp, va practicar un dibuix simple i constructiu,
passant d'un inventari topogràfic a una anàlisi complexa del paisatge. Emmanuel de
Martonne ha estat el fundador d'una escola de cartografia a la Universitat de la Sorbona
i el pedagog dels exercicis gràfics canònics per al geògraf. Pierre Deffontaines va seguir les
seves lliçons i produí una obra gràfica immensa, moltes vegades utilitzada per a il·lustrar les
seves publicacions. Després d'un declivi causat per la introducció de l'anàlisi quantitativa
i de l'ordinador, el croquis de terreny torna amb la relectura dels antics mestres i el retorn
del paisatge i de la sensibilitat al camp de la geografia.La Escuela francesa de Geografía ha desarrollado el croquis de terreno y el dibujo de

ámbito geográfico.The field trip drawings of the French School of Geography
(Paul Vidal de La Blache and Pierre Deffontaines).
The French school of geography developed all kind of tools such as field diagrams,
and drawings of profiles and of the scenery for the analysis of the landscape and particularly
for the understanding of the relationship between human societies and their
physical environments. Paul Vidal de La Blache was the pioneer in this field, practicing
a very simple and constructive drawing, from topographic records to complex landscape
analysis. Emmanuel de Martonne was the founding father of the cartographic school of
the Sorbonne University in Paris, and a geography pedagogue using his canonic graphic exercises. Pierre Deffontaines followed De Martonne lessons and produced an enormous
graphic legacy, often used in his publications. After a decline in these techniques caused
by the introduction of the use of quantitative analysis and computers, field drawings
is coming back with a new reading of the old masters, and by the renewed interest on
landscape and a more sensible geography
Growing Pains for the Los Angeles Healthy Kids Program: Findings From the Second Evaluation Case Study (Nov 2008)
Analyzes the initiative's continued efforts to provide health insurance for poor children ineligible for Medi-Cal or Healthy Families, as well as the challenges it faces, including the enrollment hold placed on 6- to 18-year-olds due to funding shortages
Characterisation of chaos in meteoroid streams. Application to the Geminids
Dynamically linking a meteor shower with its parent body can be challenging.
This is in part due to the limits of the tools available today (such as
D-criteria) but is also due to the complex dynamics of meteoroid streams. We
choose a method to study chaos in meteoroid streams and apply it to the Geminid
meteoroid stream. We decided to draw chaos maps. Amongst the chaos indicators
we studied, we show that the orthogonal fast Lyapunov indicator is particularly
well suited to our problem. The maps are drawn for three bin sizes, ranging
from to m. We show the influence of mean-motion resonances
with the Earth and with Venus, which tend to trap the largest particles. The
chaos maps present three distinct regimes in eccentricity, reflecting close
encounters with the planets. We also study the effect of non-gravitational
forces. We determine a first approximation of the particle size
needed to counterbalance the resonances with the diffusion due to the
non-gravitational forces. We find that, for the Geminids, lies in the
range m. However, depends on the orbital phase
space.Comment: 14 pages, 14 figures, Published in A&
MIREOT: the Minimum Information to Reference an External Ontology Term
While the Web Ontology Language (OWL) provides a mechanism to import ontologies, this mechanism is not always suitable. First, given the current state of editing tools and the issues they have working with large ontologies, direct OWL imports have sometimes proven impractical for day-to-day development. Second, ontologies chosen for integration may be under active development and not aligned with the chosen design principles. Importing heterogeneous ontologies in their entirety may lead to inconsistencies or unintended inferences. In this paper we propose a set of guidelines for importing required terms from an external resource into a target ontology. We describe the guidelines, their implementation, present some examples of application, and outline future work and extensions
