The role of sites of special scientific interest (SSSIs) in the conservation of British rivers

This paper discusses the particular contribution of the SSSI (Sites of Special Scientific Interest) as a way of nature conservation for rivers. In 1989, the Nature Conservancy Council proposed a dual selection system for selection of rivers; either (1) "Whole river" SSSIs representing the main types of river, or rivers which show classic and representative transitions down their lengths, or (2) "Sectional" SSSIs which are shorter stretches of river with high nature conservation interest. The NCC has recently classified all SSSIs with a river interest into 4 categories: - river SSSIs, river valley SSSIs, river adds interest - where the river clearly adds biological interest to the site, and rivers of incidental interest. The overall length of river SSSIs amounts to almost 1000 km.

A brief history of the scientific study of tropical African inland waters

An account is given of a study of African tropical waters, drawing on the personal experiences of the author. Reviewing developments since 1900, the author examines the way in which research has developed and the influence the changes in the policitcal map of Africa, in particular the change from colonial rule, has had on research.

Studies on the mouth size of fish larvae. Method and conclusions only [Translation from: Bulletin of the Japanese Society of Scientific Fisheries 36, 353-368, 1970]

This study was conducted to look into the relationship between mouth size and the total length of larval fish, and the growth in total length of larval fish in one or within a one-year period. Study material was gathered in the South China Sea, the Bay of Bangkok and the Vietnamese coast. This translation focuses on methods and conclusions of the original (longer) paper.

Scientific investigations into the eutrophication of the Norfolk Broads

The word ”Broads” is used to describe a series of relatively shallow lakes resulting from the flooding of medieval peat diggings. Broadland is essentially freshwater, but because the rivers have such low gradients the lower reaches are brackish. The influence of tide is particularly apparent on the River Yare; in Norwich 40 km from the sea there is a vertical movement of half a metre at spring tide. This study examines the problems that the broadlands are facing. The problems are basically the progressive loss of aquatic plants, in particular the macro- phytes, animal life, outbreaks of avian botulism, occasional fish kills due to a toxin produced by the blue-green alga Prymesium parvum and the emergence of very heavy algal blooms. The main factor for the deteriation of the Broaslands is the eutrophication resulting from enhanced nutrient inputs, in particular of nitrates and phosphates, from a variety of sources. The most important of these are sewage effluents, agricultural drainage, which includes fertilisers and nutrient rich effluents from piggeries and dairy un

Aprendendo o uso das ervas: a trajetória de terapeutas populares

A utilização de ervas e plantas para finalidades terapêuticas é bastante antiga e registrada em várias sociedades. Esta pesquisa procura investigar como se dá o processo de construção e reprodução do conhecimento em medicina popular (particularmente o cuidado com ervas e plantas medicinais) através da história de vida de terapeutas populares pessoas que se tornaram referências em suas comunidades por adquirir, praticar e transmitir esse conhecimento. Tem como objetivos conhecer e compreender o processo de construção do conhecimento sobre plantas medicinais por terapeutas populares do município do Rio de Janeiro; compreender as formas de reprodução deste conhecimento; entender o contexto de relações destes terapeutas com o saber científico. Utilizou-se como opção metodológica a história oral com ênfase na história de vida. Foram entrevistados sete terapeutas populares de diferentes bairros do município. Observou-se que o conhecimento em relação às ervas medicinais não está restrito a um pequeno grupo e limitado a uma forma de transmissão oral. O conhecimento tem se reproduzido, mas também tem se modificado, mesclando-se com outras formas de conhecimento e entremeado por diversas fontes de informação que vão desde a transmissão oral até informações disponíveis na mídia. A principal forma de reprodução do conhecimento parece ser a perpetuação do negócio, que evoca o discurso do tradicional, a natureza das ervas e suas propriedades benéficas e se sustenta por uma rede de informação que se utiliza dos diversos meios de comunicação e uma rede de produção e comércio que garante o sustento econômico dos terapeutas populares. A transformação das práticas de utilização de ervas medicinais em patrimônio cultural ou negócio de família além de garantir a perpetuação do conhecimento, garante um espaço diferente dentro das práticas de cuidado em saúde. As relações dos terapeutas com a medicina oficial não são relações de tensões, embora haja criticas, mas de interposição de sistemas terapêuticos.

Image-Based Delineation and Classification of Built Heritage Masonry

Fundacion Zain is developing new built heritage assessment protocols. The goal is to objectivize and standardize the analysis and decision process that leads to determining the degree of protection of built heritage in the Basque Country. The ultimate step in this objectivization and standardization effort will be the development of an information and communication technology (ICT) tool for the assessment of built heritage. This paper presents the ground work carried out to make this tool possible: the automatic, image-based delineation of stone masonry. This is a necessary first step in the development of the tool, as the built heritage that will be assessed consists of stone masonry construction, and many of the features analyzed can be characterized according to the geometry and arrangement of the stones. Much of the assessment is carried out through visual inspection. Thus, this process will be automated by applying image processing on digital images of the elements under inspection. The principal contribution of this paper is the automatic delineation the framework proposed. The other contribution is the performance evaluation of this delineation as the input to a classifier for a geometrically characterized feature of a built heritage object. The element chosen to perform this evaluation is the stone arrangement of masonry walls. The validity of the proposed framework is assessed on real images of masonry walls.

A field guide for Agency staff operating the SIMRAD EY500 portable scientific echosounder. 2nd draft 3rd August 1999

This manual has been produced by members of the national acoustics group (NAG) and represents the first in a series of outputs designed to promote co-ordination and consistency in Agency hydroacoustic surveys. It is designed as a field guide for Agency staff operating the SIMRAD EY500 portable scientific echosounder. It should be simplistic enough for the newcomer to EY500 to be able to set up and run a mobile hydroacoustic survey with some knowledge of the supporting theory. It should act as guidance for standardisation of survey procedures providing a concise list of settings and recommendations that can be used as a quick reference guide in the field. This manual condenses 5 years of practical experience of surveying fish populations using Simrad hardware and software for surveying large rivers and still waters throughout England and Wales. This document should be used as a companion to the manufacturers instruction manual and not act as a substitute for it.

Território, rede e cultura da tradição: o fado do século XIX no mundo do século XXI

A história do fado começa no século XIX e está entrelaçada por diversas teorias sobre suas origens, as quais continuam sendo debatidas até hoje. Inserido a Lista Representativa do Patrimônio Cultural Imaterial da Humanidade pela Organização das Nações Unidas para a Educação, a Ciência e a Cultura (UNESCO) em 2011, o fado é considerado como o principal símbolo musical de Portugal, presente na vida quotidiana social e cultural de muitos portugueses, tendo superado fronteiras geográficas, sociais, culturais, políticas e econômicas. Considera-se neste trabalho a importância do Império Português e de suas colônias, como Moçambique, Angola, Brasil e Goa, como contributos para o início do processo da disseminação do fado pelo mundo, levando para os territórios ultramarinos fragmentos da cultura portuguesa a partir do século XV, bem como o desenvolvimento do capitalismo e a fluidificação das fronteiras que, através da mídia, globalizaram o fado, mundializando-o, e catalisando nele o processo de mestiçagem entre as músicas das mais diferentes classificações (VALENTE, 2007:94), e, a influência dos fadistas, que com o surgimento das novas formas de comunicação possibilitaram a sua interação com outras culturas e, consequentemente, com outras canções. Destaca-se em sua trajetória a transformação de música exclusivamente consumida pelos transgressores da lei e da moral à música representativa da cultura de um país, deixando para trás as casas de má fama do século XIX e ganhando espaço pelos palcos do mundo no século XXI. A indústria fonográfica e também o rádio constituem ferramentas que colaboraram para o desenvolvimento do fado. O objetivo desta dissertação é observar o fado na atualidade, recuperando sua história desde as origens no século XIX. Para isso identifica e localiza as diversas transformações ao longo do tempo e personagens que se destacaram durante este percurso, mostrando como as tradições são reinventadas pelas novas gerações que, em vários momentos, são responsáveis pelo zelo e, muitas vezes, pela reinvenção do fado como herança cultural. Nesta análise a globalização da cultura é considerada como um poder redefinidor do significado de uma tradição. Alguns fadistas serão os pontos de referência desta pesquisa, representativos de uma linha do tempo que se distribui em 200 anos de história. As letras de fado percorrerão esta pesquisa com o intuito de ilustrar os pontos abordados. Como pesquisa cartográfica apoiada no modelo dos rizomas proposto por Gilles Deleuze e Félix Guattari (2000), pretende-se analisar a história contemporânea do fado, tendo como marco temporal a Revolução dos Cravos decorrida em 25 de abril de 1974.

La persona investigadora del patrimonio histórico-educativo como cernedora en la Sociedad de la Información: de la infoxicación hacia conocimiento

[ES] El concepto de historia del patrimonio histórico-educativo ha ido cambiando acorde con la aparición de nuevas formas de comunicarnos. Hemos pasado de estar en archivos nacionales o autonómicos para conseguir documentos, a poder hacerlo desde la comodidad de nuestro hogar a través de unos simples clics. A pesar de ello, esta suerte de aventura sólo puede llevarse a buen término cuando aprendamos a ser investigadores-cernedores. Cuando aprendamos a separar con nuestro cedazo la información veraz, presumible de poder erigirse en conocimiento científico, de aquella infoxicada que distorsiona y llena de ruidos nuestras pesquisas como personas historiadoras.

A meta-analytic approach to quantifying scientific uncertainty in stock assessments

Quantifying scientific uncertainty when setting total allowable catch limits for fish stocks is a major challenge, but it is a requirement in the United States since changes to national fisheries legislation. Multiple sources of error are readily identifiable, including estimation error, model specification error, forecast error, and errors associated with the definition and estimation of reference points. Our focus here, however, is to quantify the influence of estimation error and model specification error on assessment outcomes. These are fundamental sources of uncertainty in developing scientific advice concerning appropriate catch levels and although a study of these two factors may not be inclusive, it is feasible with available information. For data-rich stock assessments conducted on the U.S. west coast we report approximate coefficients of variation in terminal biomass estimates from assessments based on inversion of the assessment of the model’s Hessian matrix (i.e., the asymptotic standard error). To summarize variation “among” stock assessments, as a proxy for model specification error, we characterize variation among multiple historical assessments of the same stock. Results indicate that for 17 groundfish and coastal pelagic species, the mean coefficient of variation of terminal biomass is 18%. In contrast, the coefficient of variation ascribable to model specification error (i.e., pooled among-assessment variation) is 37%. We show that if a precautionary probability of overfishing equal to 0.40 is adopted by managers, and only model specification error is considered, a 9% reduction in the overfishing catch level is indicated.

The scientific legacy of the "Instituto Eduardo Torroja" in Bilbao (1960-1980)

By means of this analysis, we have endeavored to evaluate and understand both the influence that the IETcc started to bear on scientific progress in Bilbao, mainly during the 1960s and the 1970s, as well as the determined efforts of the local financial and industrial elite of the time to transform Bilbao into the great metropolis of the north, i.e. the economic capital of that part of Spain, using as a model, among other metropolises, New York, the financial capital of America, and Pittsburg, the industrial capital. The various means to accomplish this have been studied: from the institutions of investigation, exposition and information which would initiate the longed for scientific progress, to the pathways for reproducing the fascinating American way.

Ancient DNA from South-East Europe Reveals Different Events during Early and Middle Neolithic Influencing the European Genetic Heritage

The importance of the process of Neolithization for the genetic make-up of European populations has been hotly debated, with shifting hypotheses from a demic diffusion (DD) to a cultural diffusion (CD) model. In this regard, ancient DNA data from the Balkan Peninsula, which is an important source of information to assess the process of Neolithization in Europe, is however missing. In the present study we show genetic information on ancient populations of the South-East of Europe. We assessed mtDNA from ten sites from the current territory of Romania, spanning a time-period from the Early Neolithic to the Late Bronze Age. mtDNA data from Early Neolithic farmers of the Starcevo Cris culture in Romania (Carcea, Gura Baciului and Negrilesti sites), confirm their genetic relationship with those of the LBK culture (Linienbandkeramik Kultur) in Central Europe, and they show little genetic continuity with modern European populations. On the other hand, populations of the Middle-Late Neolithic (Boian, Zau and Gumelnita cultures), supposedly a second wave of Neolithic migration from Anatolia, had a much stronger effect on the genetic heritage of the European populations. In contrast, we find a smaller contribution of Late Bronze Age migrations to the genetic composition of Europeans. Based on these findings, we propose that permeation of mtDNA lineages from a second wave of Middle-Late Neolithic migration from North-West Anatolia into the Balkan Peninsula and Central Europe represent an important contribution to the genetic shift between Early and Late Neolithic populations in Europe, and consequently to the genetic make-up of modern European populations.
