Several superstructure design methodologies have been developed for low volume road bridges by the Iowa State University Bridge Engineering Center. However, to date no standard abutment designs have been developed. Thus, there was a need to establish an easy to use design methodology in addition to generating generic abutment standards and other design aids for the more common substructure systems used in Iowa. The final report for this project consists of three volumes. The first volume (this volume) summarizes the research completed in this project. A survey of the Iowa County Engineers was conducted from which it was determined that while most counties use similar types of abutments, only 17 percent use some type of standard abutment designs or plans. A literature review revealed several possible alternative abutment systems for future use on low volume road bridges in addition to two separate substructure lateral load analysis methods. These consisted of a linear and a non-linear method. The linear analysis method was used for this project due to its relative simplicity and the relative accuracy of the maximum pile moment when compared to values obtained from the more complex non-linear analysis method. The resulting design methodology was developed for single span stub abutments supported on steel or timber piles with a bridge span length ranging from 20 to 90 ft and roadway widths of 24 and 30 ft. However, other roadway widths can be designed using the foundation design template provided. The backwall height is limited to a range of 6 to 12 ft, and the soil type is classified as cohesive or cohesionless. The design methodology was developed using the guidelines specified by the American Association of State Highway Transportation Officials Standard Specifications, the Iowa Department of Transportation Bridge Design Manual, and the National Design Specifications for Wood Construction. The second volume introduces and outlines the use of the various design aids developed for this project. Charts for determining dead and live gravity loads based on the roadway width, span length, and superstructure type are provided. A foundation design template was developed in which the engineer can check a substructure design by inputting basic bridge site information. Tables published by the Iowa Department of Transportation that provide values for estimating pile friction and end bearing for different combinations of soils and pile types are also included. Generic standard abutment plans were developed for which the engineer can provide necessary bridge site information in the spaces provided. These tools enable engineers to design and detail county bridge substructures more efficiently. The third volume provides two sets of calculations that demonstrate the application of the substructure design methodology developed in this project. These calculations also verify the accuracy of the foundation design template. The printouts from the foundation design template are provided at the end of each example. Also several tables provide various foundation details for a pre-cast double tee superstructure with different combinations of soil type, backwall height, and pile type.

Head and neck squamous cell carcinomas are frequently diagnosed at an advanced stage. Their treatment remains controversial, and has to be multidisciplinary. External beam radiotherapy is a recognized treatment option after radical curative surgery in order to improve local control. Different adjuvant treatment options have been studied in order to improve the outcome of these patients. We review in this paper the different prognostic factors indicating an adjuvant treatment and the interest of treatment intensification in bad prognostic patients.

The ASTM standards on Writing Ink Identification (ASTM 1789-04) and on Writing Ink Comparison (ASTM 1422-05) are the most up-to-date guidelines that have been published on the forensic analysis of ink. The aim of these documents is to cover most aspects of the forensic analysis of ink evidence, from the analysis of ink samples, the comparison of the analytical profile of these samples (with the aim to differentiate them or not), through to the interpretation of the result of the examination of these samples in a forensic context. Significant evolutions in the technology available to forensic scientists, in the quality assurance requirements brought onto them, and in the understanding of frameworks to interpret forensic evidence have been made in recent years. This article reviews the two standards in the light of these evolutions and proposes some practical improvements in terms of the standardization of the analyses, the comparison of ink samples, and the interpretation of ink examination. Some of these suggestions have already been included in a DHS funded project aimed at creating a digital ink library for the United States Secret Service.

The NRS state data quality standards identify the policies, processes and materials that states and local programs should have in place to collect valid and reliable data for the National Reporting System (NRS). The Division of Adult Education (DAEL) within the Office of Vocational and Adult Education developed the standards to define the characteristics of high quality state and local data collection systems for the NRS. The standards provide an organized way for DAEL to understand the quality of NRS data collection within the states and also provide guidance to states on how to improve their systems. States are to complete this checklist, which incorporates the standards, with their annual NRS data submission to rate their level of implementation of the standards. The accompanying policy document describes DAEL’s requirements for state conformance to the standards and explains the use of the information from this checklist.

A Cultura pode ser definida de várias maneiras e cada autor tem uma visão própria do termo mas, genericamente, cultura pode ser entendida como o conjunto de características humanas que não são inatas e que se criam, preservam ou aprimoram com o convívio na sociedade, com a comunicação e cooperação entre indivíduos. Os membros de uma sociedade não estão conscientes dos seus valores culturais e somente percebem estes valores quando entram em “choque” com uma cultura diferente. Estas diferenças culturais podem criar confusões e mal-entendidos. As culturas Portuguesa e a Brasileira parecem ser bastante semelhantes: a mesma língua, as mesmas crenças, religião predominantemente católica e alimentos similares. Porém, apesar das semelhanças, e após entrevistas de carácter narrativo, observou-se nestas duas culturas características próprias e que muitas vezes foram necessárias adaptações para uma melhor integração na sociedade. Esta tese de mestrado é uma análise das diferenças culturais entre Portugal e Brasil e tem por objectivo encontrar standards culturais de ambos os países podendo ser um instrumento de ajuda para aqueles que vêm do Brasil para Portugal, e vice-versa, para trabalharem ou abrirem uma empresa. Os standards culturais encontrados, após análise comparativa, estão relacionados com a maneira de ver a vida, de ultrapassar os problemas e pressões do dia a dia, com colectivismo, hierarquia, simpatia, preocupação com o cliente, ansiedade face à incerteza e profissionalismo. Este trabalho termina com a identificação dos standards culturais e com dicas para aqueles que saem do seu país e recomeçam a sua vida noutro com cultura diferente

Mountain ranges are biodiversity hotspots worldwide and provide refuge to many organisms under contemporary climate change. Gathering field information on mountain biodiversity over time is of primary importance to understand the response of biotic communities to climate changes. For plants, several long-term observation sites and networks of mountain biodiversity are emerging worldwide to gather field data and monitor altitudinal range shifts and community composition changes under contemporary climate change. Most of these monitoring sites, however, focus on alpine ecosystems and mountain summits, such as the global observation research initiative in alpine environments (GLORIA). Here we describe the Alps Vegetation Database, a comprehensive community level archive (GIVD ID EU-00-014) which aims at compiling all available geo-referenced vegetation plots from lowland forests to alpine grasslands across the greatest mountain range in Europe: the Alps. This research initiative was funded between 2008 and 2011 by the Danish Council for Independent Research and was part of a larger project to compare cross-scale plant community structure between the Alps and the Scandes. The Alps Vegetation Database currently harbours 35,731 geo-referenced vegetation plots and 5,023 valid taxa across Mediterranean, temperate and alpine environments. The data are mainly used by the main contributors of the Alps Vegetation Database in an ecoinformatics approach to test hypotheses related to plant macroecology and biogeography, but external proposals for joint collaborations are welcome.

Abstract OBJECTIVE To determine time standards for interventions and activities conducted by nursing professionals in Family Health Units (FHU) in Brazil to substantiate the calculation of work force. METHOD This was an observational study carried out in 27 FHU, in 12 municipalities in 10 states, in 2013. In each unit, nursing professionals were observed every 10 minutes, for eight work hours, on five consecutive days via the work sampling technique. RESULTS A total of 32,613 observations were made, involving 47 nurses and 93 nursing technicians/assistants. Appointments were the main intervention carried out by nurses, with a mean time of 25.3 minutes, followed by record-keeping, which corresponded to 9.7%. On average, nursing technicians/assistants spent 6.3% of their time keeping records and 30.6 intervention minutes on immunization/vaccination control. CONCLUSION The study resulted in standard times of interventions carried out by the FHU nursing team, which can underpin the determination of nursing staff size and human resource policies. Furthermore, the study showed the panorama of interventions currently employed, allowing for the work process to be reviewed and optimized.

We analyze the effects of a domestic standard that reduces an externality associated with the consumption of the good targeted by the standard, using a model in which foreign and domestic producers compete in the domestic good market. Producers can reduce expected damage associated with the externality by incurring a cost that varies by source of origin. Despite potential protectionism, the standard is useful in correcting the consumption externality in the domestic country. Protectionism occurs when the welfare-maximizing domestic standard is higher than the international standard maximizing welfare inclusive of foreign profits. The standard is actually anti-protectionist when foreign producers are much more efficient at addressing the externality than are domestic producers. Possible exclusion of domestic or foreign producers arises with large standards, which may alter the classification of a standard as protectionist or non-protectionist. The paper provides important implications for the estimation and use of tariff equivalents of nontariff barriers.

When did overseas trade start to matter for living standards? Traditional real-wage indices suggest that living standards in Europe stagnated before 1800. In this paper, we argue thatwelfare rose substantially, but surreptitiously, because of an influx of new goods as a result ofoverseas trade. Colonial luxuries such as tea, coffee, and sugar transformed European diets afterthe discovery of America and the rounding of the Cape of Good Hope. These goods became household items in many countries by the end of the 18th century. We use three different methodsto calculate welfare gains based on price data and the rate of adoption of these new colonialgoods. Our results suggest that by 1800, the average Englishman would have been willing to forego 10% or more of his income in order to maintain access to sugar and tea alone. These findings are robust to a wide range of alternative assumptions, data series, and valuation methods.

We propose a model in which economic relations and institutions in advancedand less developed economies differ as these societies have access to different amounts of information. This lack of information makes it hard to give the right incentives to managers and entrepreneurs. We argue that differences in the amount of information arise because of the differences in the scale of activities in rich and poor economies; namely, there is too little repetition of similar activities in pooreconomies, thus insufficient information to set the appropriate standards for firm performance. Our model predicts a number of institutional and structural transformations as the economy accumulates capital and information.

The Standards and Accreditation program exists to encourage the ongoing development of high quality public library services in Iowa. In Service to Iowa: Public Library Standards is the manual for the State Library of Iowa’s standards program. It was first published in 1985 and was updated in 1989, 1997, 2004, and now in 2010. Iowa’s voluntary public library standards program was established to give public libraries a tool to identify strengths and areas for improvement. It is also used to document the condition of public library service in Iowa, to distribute Direct State Aid funding, and to meet statutory requirements. In 2010, the Iowa Commission of Libraries appointed the Public Library Standards Advisory Task Force to revise In Service to Iowa. The Task Force included members representing libraries from different size categories, the Iowa Commission of Libraries, Library Service Area staff, and State Library staff. All members support and stress the importance of the accreditation process and thank the Iowa public library community for its assistance.
