A program manual to assist with implementation of a volunteer health and wellness program

Based on the success of a community health and wellness program, Wellness in the City, delivered in Dallas County by trained volunteers, Texas Cooperative Extension (TCE) decided to pilot the program in 16 counties in North and East Texas. Before implementing the program, TCE wanted the Dallas County program to be reviewed and revised as needed to meet the diverse community needs in the pilot counties. TCE also asked for an implementation manual to be developed for the county agents to utilize. ^ To achieve these objectives, I first reviewed literature on other volunteer-implemented health interventions in the U.S. to see how they were planned, disseminated, implemented, and evaluated. Next, I reviewed the Wellness in the City program and materials. I applied all the information I gathered up to that point to the program development committee meetings (committee included seven TCE county agents, a TCE regional program director, and me). The program structure and training materials were revised based on our research and program implementation experience. These changes were made to ensure adequate training for the volunteers and to create a program that is applicable in the communities it will be piloted in. ^ With the program structure and training presentations developed, next I focused on compiling the implementation manual, which includes program details and volunteer recruitment, training, and management materials. The goal was to create a manual with everything the county agents will need to implement the program, so they can focus their efforts on putting the manual to use and recruiting and managing the volunteers. The final step was developing a program evaluation form for the agents to complete. It includes questions to assess the agents' thoughts about the training content, the feasibility of implementing the program using the manual, and the challenges of the program. ^

Statistics of the National soil test database of France

In France, farmers commission about 250,000 soil-testing analyses per year to assist them managing soil fertility. The number and diversity of origin of the samples make these analyses an interesting and original information source regarding cultivated topsoil variability. Moreover, these analyses relate to several parameters strongly influenced by human activity (macronutrient contents, pH...), for which existing cartographic information is not very relevant. Compiling the results of these analyses into a database makes it possible to re-use these data within both a national and temporal framework. A database compilation relating to data collected over the period 1990-2009 has been recently achieved. So far, commercial soil-testing laboratories approved by the Ministry of Agriculture have provided analytical results from more than 2,000,000 samples. After the initial quality control stage, analytical results from more than 1,900,000 samples were available in the database. The anonymity of the landholders seeking soil analyses is perfectly preserved, as the only identifying information stored is the location of the nearest administrative city to the sample site. We present in this dataset a set of statistical parameters of the spatial distributions for several agronomic soil properties. These statistical parameters are calculated for 4 different nested spatial entities (administrative areas: e.g. regions, departments, counties and agricultural areas) and for 4 time periods (1990-1994, 1995-1999, 2000-2004, 2005-2009). Two kinds of agronomic soil properties are available: the firs one correspond to the quantitative variables like the organic carbon content and the second one corresponds to the qualitative variables like the texture class. For each spatial unit and temporal period, we calculated the following statistics stets: the first set is calculated for the quantitative variables and corresponds to the number of samples, the mean, the standard deviation and, the 2-,4-,10-quantiles; the second set is calculated for the qualitative variables and corresponds to the number of samples, the value of the dominant class, the number of samples of the dominant class, the second dominant class, the number of samples of the second dominant class.

Turbidite recognition and radiocarbon ages of marine sediment cores along the continental margin of Chile

Much progress has been made in estimating recurrence intervals of great and giant subduction earthquakes using terrestrial, lacustrine, and marine paleoseismic archives. Recent detailed records suggest these earthquakes may have variable recurrence periods and magnitudes forming supercycles. Understanding seismic supercycles requires long paleoseismic archives that record timing and magnitude of such events. Turbidite paleoseismic archives may potentially extend past earthquake records to the Pleistocene and can thus complement commonly shorter-term terrestrial archives. However, in order to unambiguously establish recurring seismicity as a trigger mechanism for turbidity currents, synchronous deposition of turbidites in widely spaced, isolated depocenters has to be ascertained. Furthermore, characteristics that predispose a seismically active continental margin to turbidite paleoseismology and the correct sample site selection have to be taken into account. Here we analyze 8 marine sediment cores along 950 km of the Chile margin to test for the feasibility of compiling detailed and continuous paleoseismic records based on turbidites. Our results suggest that the deposition of areally widespread, synchronous turbidites triggered by seismicity is largely controlled by sediment supply and, hence, the climatic and geomorphic conditions of the adjacent subaerial setting. The feasibility of compiling a turbidite paleoseismic record depends on the delicate balance between sufficient sediment supply providing material to fail frequently during seismic shaking and sufficiently low sedimentation rates to allow for coeval accumulation of planktonic foraminifera for high-resolution radiocarbon dating. We conclude that offshore northern central Chile (29-32.5°S) Holocene turbidite paleoseismology is not feasible, because sediment supply from the semi-arid mainland is low and almost no Holocene turbidity-current deposits are found in the cores. In contrast, in the humid region between 36 and 38°S frequent Holocene turbidite deposition may generally correspond to paleoseismic events. However, high terrigenous sedimentation rates prevent high-resolution radiocarbon dating. The climatic transition region between 32.5 and 36°S appears to be best suited for turbidite paleoseismology.

Database of Ice-Rich Yedoma Permafrost (IRYP)

Vast portions of Arctic and sub-Arctic Siberia, Alaska and the Yukon Territory are covered by ice-rich silty to sandy deposits that are containing large ice wedges, resulting from syngenetic sedimentation and freezing. Accompanied by wedge-ice growth in polygonal landscapes, the sedimentation process was driven by cold continental climatic and environmental conditions in unglaciated regions during the late Pleistocene, inducing the accumulation of the unique Yedoma deposits up to >50 meters thick. Because of fast incorporation of organic material into syngenetic permafrost during its formation, Yedoma deposits include well-preserved organic matter. Ice-rich deposits like Yedoma are especially prone to degradation triggered by climate changes or human activity. When Yedoma deposits degrade, large amounts of sequestered organic carbon as well as other nutrients are released and become part of active biogeochemical cycling. This could be of global significance for future climate warming as increased permafrost thaw is likely to lead to a positive feedback through enhanced greenhouse gas fluxes. Therefore, a detailed assessment of the current Yedoma deposit coverage and its volume is of importance to estimate its potential response to future climate changes. We synthesized the map of the coverage and thickness estimation, which will provide critical data needed for further research. In particular, this preliminary Yedoma map is a great step forward to understand the spatial heterogeneity of Yedoma deposits and its regional coverage. There will be further applications in the context of reconstructing paleo-environmental dynamics and past ecosystems like the mammoth-steppe-tundra, or ground ice distribution including future thermokarst vulnerability. Moreover, the map will be a crucial improvement of the data basis needed to refine the present-day Yedoma permafrost organic carbon inventory, which is assumed to be between 83±12 (Strauss et al., 2013, doi:10.1002/2013GL058088) and 129±30 (Walter Anthony et al., 2014, doi:10.1038/nature13560) gigatonnes (Gt) of organic carbon in perennially-frozen archives. Hence, here we synthesize data on the circum-Arctic and sub-Arctic distribution and thickness of Yedoma for compiling a preliminary circum-polar Yedoma map. For compiling this map, we used (1) maps of the previous Yedoma coverage estimates, (2) included the digitized areas from Grosse et al. (2013) as well as extracted areas of potential Yedoma distribution from additional surface geological and Quaternary geological maps (1.: 1:500,000: Q-51-V,G; P-51-A,B; P-52-A,B; Q-52-V,G; P-52-V,G; Q-51-A,B; R-51-V,G; R-52-V,G; R-52-A,B; 2.: 1:1,000,000: P-50-51; P-52-53; P-58-59; Q-42-43; Q-44-45; Q-50-51; Q-52-53; Q-54-55; Q-56-57; Q-58-59; Q-60-1; R-(40)-42; R-43-(45); R-(45)-47; R-48-(50); R-51; R-53-(55); R-(55)-57; R-58-(60); S-44-46; S-47-49; S-50-52; S-53-55; 3.: 1:2,500,000: Quaternary map of the territory of Russian Federation, 4.: Alaska Permafrost Map). The digitalization was done using GIS techniques (ArcGIS) and vectorization of raster Images (Adobe Photoshop and Illustrator). Data on Yedoma thickness are obtained from boreholes and exposures reported in the scientific literature. The map and database are still preliminary and will have to undergo a technical and scientific vetting and review process. In their current form, we included a range of attributes for Yedoma area polygons based on lithological and stratigraphical information from the original source maps as well as a confidence level for our classification of an area as Yedoma (3 stages: confirmed, likely, or uncertain). In its current version, our database includes more than 365 boreholes and exposures and more than 2000 digitized Yedoma areas. We expect that the database will continue to grow. In this preliminary stage, we estimate the Northern Hemisphere Yedoma deposit area to cover approximately 625,000 km². We estimate that 53% of the total Yedoma area today is located in the tundra zone, 47% in the taiga zone. Separated from west to east, 29% of the Yedoma area is found in North America and 71 % in North Asia. The latter include 9% in West Siberia, 11% in Central Siberia, 44% in East Siberia and 7% in Far East Russia. Adding the recent maximum Yedoma region (including all Yedoma uplands, thermokarst lakes and basins, and river valleys) of 1.4 million km² (Strauss et al., 2013, doi:10.1002/2013GL058088) and postulating that Yedoma occupied up to 80% of the adjacent formerly exposed and now flooded Beringia shelves (1.9 million km², down to 125 m below modern sea level, between 105°E - 128°W and >68°N), we assume that the Last Glacial Maximum Yedoma region likely covered more than 3 million km² of Beringia.

Adjustment methods of national input-output tables for harmonized and consistent multi-regional input-output databases

Despite the fact that input–output (IO) tables form a central part of the System of National Accounts, each individual country's national IO table exhibits more or less different features and characteristics, reflecting the country's socioeconomic idiosyncrasies. Consequently, the compilers of a multi-regional input–output table (MRIOT) are advised to thoroughly examine the conceptual as well as methodological differences among countries in the estimation of basic statistics for national IO tables and, if necessary, to carry out pre-adjustment of these tables into a common format prior to the MRIOT compilation. The objective of this study is to provide a practical guide for harmonizing national IO tables to construct a consistent MRIOT, referring to the adjustment practices used by the Institute of Developing Economies, JETRO (IDE-JETRO) in compiling the Asian International Input–Output Table.

The Effect That Project Management Certification Has on Employability: Agent's Perceptions from Spain

This study analyses the effects that the project management certification has on employability. This analysis started with a participative process in which various groups of experts who are involved in the certification of people were consulted. A personal interview was carried out amongst 106 professionals —certifying bodies, training institutions, the civil service, and international organisations— and amongst professional who are certified in project management by the International Project Management Association in Spain. The results show that the certification emerges as a powerful tool for improving employability. The effects are demonstrated across two complementary aspects: internal company aspects and external aspects relating to the labour market. Finally, by compiling the different agents’ opinions, a series of measures emerge for improving the accreditation processes as an employability tool and increasing the mutual learning between public and private actors.

E.1027. Maison en bord de mer: Theoretical Restoration

E.1027, Maison en bord de mer is a small villa in Roquebrune Cap-Martin, built by architects Eileen Gray and Jean Badovici between 1926 and 1929. It was hailed as a landmark of modern architecture, and then forgotten. Over the years many transformations have been carried out, and these changes have altered the spatial qualities of the original project. Time and neglect have taken their toll, and until 2008 the villa was abandoned, a shadow of its former self. In order to state an appropriate restoration, a description of the house and its historic evolution has been made, comparing plans of its different transformations. After compiling the most common pathologies and restoration procedures in buildings of the Modern Movement in general, the particular pathologies of E.1027 are presented, concluding with a restoration proposal for E.1027 that considers aesthetical as well as technical aspects. This study involves an attempt to establish guidelines for the theoretical and technical aspects for restoration of architecture of the Modern Movement, using the Maison en bord de mer as an example.

Arquitectura de información para medicion de rendimiento en entornos e-manufacturing

La implantación de las tecnologías Internet ha permitido la extensión del uso de estrategias e-manufacturing y el desarrollo de herramientas para la recopilación, transformación y sincronización de datos de fabricación vía web. En este ámbito, un área de potencial desarrollo es la extensión del virtual manufacturing a los procesos de Performance Management (PM), área crítica para la toma de decisiones y ejecución de acciones de mejora en fabricación. Este trabajo doctoral propone un Arquitectura de Información para el desarrollo de herramientas virtuales en el ámbito PM. Su aplicación permite asegurar la interoperabilidad necesaria en los procesos de tratamiento de información de toma de decisión. Está formado por tres sub-sistemas: un modelo conceptual, un modelo de objetos y un marco Web compuesto de una plataforma de información y una arquitectura de servicios Web (WS). El modelo conceptual y el modelo de objetos se basa en el desarrollo de toda la información que se necesita para definir y obtener los diferentes indicadores de medida que requieren los procesos PM. La plataforma de información hace uso de las tecnologías XML y B2MML para estructurar un nuevo conjunto de esquemas de mensajes de intercambio de medición de rendimiento (PMXML). Esta plataforma de información se complementa con una arquitectura de servicios web que hace uso de estos esquemas para integrar los procesos de codificación, decodificación, traducción y evaluación de los performance key indicators (KPI). Estos servicios realizan todas las transacciones que permiten transformar los datos origen en información inteligente usable en los procesos de toma de decisión. Un caso práctico de intercambio de datos en procesos de medición del área de mantenimiento de equipos es mostrado para verificar la utilidad de la arquitectura. ABSTRAC The implementation of Internet technologies has led to e-Manufacturing technologies becoming more widely used and to the development of tools for compiling, transforming and synchronizing manufacturing data through the Web. In this context, a potential area for development is the extension of virtual manufacturing to Performance Measurement (PM) processes, a critical area for decision-making and implementing improvement actions in manufacturing. This thesis proposes a Information Architecture to integrate decision support systems in e-manufacturing. Specifically, the proposed architecture offers a homogeneous PM information exchange model that can be applied trough decision support in emanufacturing environment. Its application improves the necessary interoperability in decision-making data processing tasks. It comprises three sub-systems: a data model, a object model and Web Framework which is composed by a PM information platform and PM-Web services architecture. . The data model and the object model are based on developing all the information required to define and acquire the different indicators required by PM processes. The PM information platform uses XML and B2MML technologies to structure a new set of performance measurement exchange message schemas (PM-XML). This PM information platform is complemented by a PM-Web Services architecture that uses these schemas to integrate the coding, decoding, translation and assessment processes of the key performance indicators (KPIs). These services perform all the transactions that enable the source data to be transformed into smart data that can be used in the decision-making processes. A practical example of data exchange for measurement processes in the area of equipment maintenance is shown to demonstrate the utility of the architecture.

Integrating software testing and run-time checking in an assertion verification framework

We have designed and implemented a framework that unifies unit testing and run-time verification (as well as static verification and static debugging). A key contribution of our approach is that a unified assertion language is used for all of these tasks. We first propose methods for compiling runtime checks for (parts of) assertions which cannot be verified at compile-time via program transformation. This transformation allows checking preconditions and postconditions, including conditional postconditions, properties at arbitrary program points, and certain computational properties. The implemented transformation includes several optimizations to reduce run-time overhead. We also propose a minimal addition to the assertion language which allows defining unit tests to be run in order to detect possible violations of the (partial) specifications expressed by the assertions. This language can express for example the input data for performing the unit tests or the number of times that the unit tests should be repeated. We have implemented the framework within the Ciao/CiaoPP system and effectively applied it to the verification of ISO-prolog compliance and to the detection of different types of bugs in the Ciao system source code. Several experimental results are presented that ¡Ilústrate different trade-offs among program size, running time, or levéis of verbosity of the messages shown to the user.

Neutron performance analysis for ESS target proposal

In the course of discussing different target types for their suitability in the European Spallation Source (ESS) one main focus was on neutronics' performance. Diverse concepts have been assessed baselining some preliminary engineering and geometrical details and including some optimization. With the restrictions and resulting uncertainty imposed by the lack of detailed designs optimizations at the time of compiling this paper, the conclusion drawn is basically that there is a little difference in the neutronic yield of the investigated targets. Other criteria like safety, environmental compatibility, reliability and cost will thus dominate the choice of an ESS target.

Estudio comparativo en el dimensionamiento de cimentaciones

El presente documento es el resultado de la participación de forma activa del autor en el equipo de la oficina de proyectos IDEAM S.A. encargada de realizar en U.T.E. con F.H.E.C.O.R. un manual de aplicación del Eurocódigo 7 a petición de la Dirección General de Carreteras del Ministerio de Fomento. El trabajo se ha centrado en la comparación entre las diversas formulaciones existentes para obtener la carga de hundimiento en cimentaciones superficiales, comparando los resultados de los distintos factores que participan en la formulación de los diferentes autores. De este modo el estudio ha servido para detectar algunas incongruencias entre las formulaciones clásicas de Brinch-Hansen y la formulación propuesta en el anexo D del Eurocódigo 7 (UNE-EN 1997-1) A sí mismo la investigación también se centra en las implicaciones que supone realizar el diseño de las cimentaciones superficiales utilizando para ello el método de los coeficientes parciales de seguridad y combinaciones de acciones mayoradas tal y como plantea el Eurocódigo 7 en lugar de realizar dicho diseño mediante el método de los coeficientes globales de seguridad y combinaciones características de acciones en la forma en que la tradición geotécnica española ha venido haciendo hasta la fecha. This document is the result of the active participation of the author in IDEAM SA, responsible for compiling a guide for the Eurocode 7 as a request by General Director of Hihways of the Fomento Ministry The work primarily focuses on the comparison between the different theories used to obtain the bearing capacity of shallow foundations and comparing the results of the multpile factors involved in the formulas designed by different authors Thereby, the present study has helped identify inconsistencies between the classical formulations of Brinch-Hansen and the proposed formulation in the Annex D of the Eurocode 7 (UNE- EN 1997-1) The investigation additionally focuses on the implications of shallow foundations desing by using the method of partial safety factors and the ULS combinations of actions instead of employing the design by the global safety factor method and SLS combinations of the actions.

La arquitectura de Curro Inza : una aproximación crítica y proyectual

El arquitecto Curro Inza (1929-1976) pertenece al grupo que se ha denominado como organicismo madrileño y Escuela de Madrid, cuyas máximas realizaciones se produjeron durante los años sesenta del pasado siglo. Hasta ahora su obra y persona han generado opiniones bien extremas, pero apenas han sido investigadas, cuando en realidad su arquitectura trata asuntos que hoy se muestran de actual interés. El estudio que aquí se presenta tiene un doble objetivo. El primero es agrupar la información arquitectónica del autor y catalogar las obras de su archivo personal (inédito hasta ahora). Se ordena, clasifica y cataloga toda la documentación arquitectónica del archivo Inza, dejándose depositada en la Biblioteca de la ETSAM, quedando disponible y facilitando posteriores investigaciones sobre este arquitecto. Se procede asimismo a la digitalizaran de los proyectos principales garantizando su optima conservación para el futuro Una vez logrado el primer objetivo, el segundo consiste en realizar un análisis proyectual y critico de su obra, un punto de vista hasta ahora apenas abordado. Me propongo profundizar en una obra definida como compleja pero poco explicada, realizando una revisión crítica de sus escritos y de sus proyectos, y relacionando esta con otras arquitecturas (nacionales e internacionales) que sitúen al autor dentro del discurso contemporáneo. Para desentrañar las claves de su arquitectura se aborda el trabajo de Inza desde cinco miradas distintas y simultaneas. Desde cada una de estas miradas o categorías) se hace una aproximación crítica recorriendo los proyectos. Unas categorías que, a la postre, conforman el índice de este trabajo. Aunque la compilación y revisión del archivo posee algo de búsqueda arqueológica, el estudio no pretende tener un interés únicamente o intrínsecamente histórico. El trabajo tiene en realidad como fin estudiar la forma de proyectar de un arquitecto hasta ahora poco referencial y que entiendo, puede hoy establecer puentes con el presente y el futuro a través de su arquitectura. Intentar entender los mecanismos que arman esta arquitectura, sus orígenes, su evolución y la construcción de su lenguaje. En resumen, explicar y analizar la obra desde un punto de vista proyectual haciendo una lectura critica que desentrañe estrategias de las que hoy pudiéramos aprender y nos resultasen operativas.ABSTRACT: The architect Curro Inza (1929-1976) belongs to the group known as Madrilian organicism and the School of Madrid, whose most important works were built during the 1960 and 1970 decades. Curro Inza's work has received up until now very different, even extreme opinions, but his work has not been studied in depth, which is surprising if we consider that his architecture treats issues which are of great interest today. The present study has aimed at two objectives. The first has been to gather the information concerned with the author and his work, and to catalog all of the works of this personal archive (unpublished up until now). The work we have done here has consisted in compiling, digitalizing, classifying and cataloguing all of the documentation found in Curro Inza's personal archive; this archive has been deposited in the Biblioteca de la Escuela Superior de Artquitectura de Madrid (ETSAM) . We have also digitalized the main projects in order to assure the best storage conditions for the future. The second objective has consisted in analyzing Curro Inza's work from a project and critical point of view, an approach which has not yet been explored. Within this second objective, I have studied Inza's work, which is well defined and personal as well as complex, but which has received little attention and has not been explained. I have done a critical revision of both his projects and his writings, and have related these with other, both national and international, architectures, in order to place Inza's work within the contemporary architectural discourse. In order to decipher the essence of Inza's architecture, I have approached his work from five, simultaneous perspectives. I have described the projects critically from each of the five perspectives or categories; these five categories give shape to the organization of the dissertation. Even if the compilation and revision of Inza's archive is somehow an archaeological search, this study aims at having a larger scope than its strict, exclusive historical interest. In this study I have studied Inza's projects from a critical point of view and in relation to contemporary architecture and architectural thought, attempting to draw connections between Inza's work and modern, present architecture. We have also attempted to understand and describe Inza's language and conception of architectural discourse, as well as his origins, evolution and expression of his thought. In summary, I have analyzed and explained Curro Inza's work from a projectual point of view, drawing a critical reading of the strategies used by the author, and from which we could learn and work today.

Impedance control for legged robots: an insight into the concepts involved

The application of impedance control strategies to modern legged locomotion is analyzed, paying special attention to the concepts behind its implementation which is not straightforward. In order to implement a functional impedance controller for a walking mechanism, the concepts of contact, impact, friction, and impedance have to be merged together. A literature review and a comprehensive analysis are presented compiling all these concepts along with a discussion on position-based versus force-based impedance control approaches, and a theoretical model of a robotic leg in contact with its environment is introduced. A theoretical control scheme for the legs of a general legged robot is also introduced, and some simulations results are presented.
