Mellan frihet och kontroll : Om läroplanskonstruktioner i svensk skola

The aim of this thesis is to explore how different competing discourses in the historical context of the Swedish education development have qualified and disqualified different constructions of national curriculum. How and after what kind of principles is the curriculum constructed? What qualify who are going to be recognized as the author and addressee of the curriculum? These key ques-tions of the study are discussed in the first part of the thesis. My point of depar-ture is that the curriculum can be understood as a relation between freedom and control. In an educational system this relationship reflects the problematic ten-sion between the external demands from an authoritative center and the local need to independently reflect over educational issues. How these concepts are defined by the prevailing social discourses affect specific relations and construc-tions of curricula as a steering tool and a producer of specific teacher identities. In this sense, I claim that curriculum is constructed in different ways depending on which of the didactic questions are emphasized and answered and who is judged as the legitimate author. Based on this, three models of curriculum con-struction are formulated; the content based, the result based and the process based. These models are subsequently used as an analytical tool to examine the historical development of Swedish national curricula. The second part of the thesis investigates the Swedish education system and the production of the national curriculum as a product of rival discourses. The historical investigation begins 1842 when the first state curriculum was issued and the inquiry concludes in 2008. The findings indicate that no one single con-struction has been totally dominant and that there has been an on-going discur-sive struggle between different alternative and opinions about what teachers must do and be.

När lanthandeln stänger : En studie av lanthandelns betydelse för flyttning in och ut och för människorna i byn

In Sweden the number of rural food shops has decreased for more than 50 years. Often the closing of a village shop is supposed to affect the migration patterns in the area it has been serving. However, according to this study, neither in- nor out-migration in the area affected by the closing is affected. The deficits of migration usual in those areas are established at least 10-12 years before the closing year. Thus, the typical closing takes place subsequent to a long term population decline. On the other hand, localities hosting a shop that survived during the study period 1990-2004 have a bigger total population and show tendencies towards decreasing deficit of migration at any potential closing year. These statistical results are supported by interviews carried out in three villages where the last shop has closed. They indicate that the shop has already lost its importance as supplier when it closes. By then the village shop is primarily used as complement to nearby towns or shopping centres. Each of the two studies accounted for here point at a relative un-importance of the village shop as a service point at the closing time. However, as it often offer the last public space in the village the village shop serves a key function as a meeting point for some households. When the shop has closed, the village holds private homes only. That is a situation increasing loneliness to some inhabitants.

Metaanalys av vargforskningen i Sverige/Norgemellan åren 2000-2014

Vargens återkomst har gett upphov till olika attitydsyttringar, boende i vargområden är i regel mernegativa till vargen än de som bor utanför dessa områden. Genom att mäta vilka attityder som finnstill varg kan forskare ge incitament till makthavare om hur vargförvaltningen upplevs avallmänheten.Den här studien är en kartläggning av forskningsläget under åren 2000 – 2014 rörande attityder tillvarg i Sverige och Norge. De variabler/grupper av individer som forskare inom området använderför att mäta vem som har vilken attityd är jägare, djurägare, boende på landsbygd utanför vargområde, boende på landsbygd i vargområde, boende i stad med flera. Vi finner att studierna tar uppteorierna social representation, centrum och periferi och NIMBY (Not In My Backyard). Manproblematiserar dessa i varierande grad utifrån de teorier som används. Något vi menar ärproblematiskt då forskningen blir enkelspårig och grund. Vi vill se en bredare problematiseringutifrån de teorier som redan framkommit i forskningen och ifrågasätter varför inte fler teorier ochvariabler undersöks. Vi efterfrågar ett vidare perspektiv där forskaren exempelvis gör tolkningarutifrån olika samhälleliga maktfigurationer.

Flood Risk Management In Small Urban River Using A Sustainable Urban Drainage System: Wortley Beck, Leeds, Uk

In the UK, urban river basins are particularly vulnerable to flash floods due to short and intense rainfall. This paper presents potential flood resilience approaches for the highly urbanised Wortley Beck river basin, south west of the Leeds city centre. The reach of Wortley Beck is approximately 6km long with contributing catchment area of 30km2 that drain into the River Aire. Lower Wortley has experienced regular flooding over the last few years from a range of sources, including Wortley Beck and surface and ground water, that affects properties both upstream and downstream of Farnley Lake as well as Wortley Ring Road. This has serious implications for society, the environment and economy activity in the City of Leeds. The first stage of the study involves systematically incorporating Wortley Beck’s land scape features on an Arc-GIS platform to identify existing green features in the region. This process also enables the exploration of potential blue green features: green spaces, green roofs, water retention ponds and swales at appropriate locations and connect them with existing green corridors to maximize their productivity. The next stage is involved in developing a detailed 2D urban flood inundation model for the Wortley Beck region using the CityCat model. CityCat is capable to model the effects of permeable/impermeable ground surfaces and buildings/roofs to generate flood depth and velocity maps at 1m caused by design storm events. The final stage of the study is involved in simulation of range of rainfall and flood event scenarios through CityCat model with different blue green features. Installation of other hard engineering individual property protection measures through water butts and flood walls are also incorporated in the CityCat model. This enables an integrated sustainable flood resilience strategy for this region.

Reducing The Risk Of Floods In Urban Areas With Combined Inland-River System

With the change of the water environment in accordance with climate change, the loss of lives and properties has increased due to urban flood. Although the importance of urban floods has been highlighted quickly, the construction of advancement technology of an urban drainage system combined with inland-river water and its relevant research has not been emphasized in Korea. In addition, without operation in consideration of combined inland-river water, it is difficult to prevent urban flooding effectively. This study, therefore, develops the uncertainty quantification technology of the risk-based water level and the assessment technology of a flood-risk region through a flooding analysis of the combination of inland-river. The study is also conducted to develop forecast technology of change in the water level of an urban region through the construction of very short-term/short-term flood forecast systems. This study is expected to be able to build an urban flood forecast system which makes it possible to support decision making for systematic disaster prevention which can cope actively with climate change.

Cidade (i)material: museografias do patrimônio cultural na cidade de Juiz de Fora/MG

Este estudo é sobre os discursos produzidos sobre o patrimônio cultural na cidade de Juiz de Fora a partir da trajetória da política pública de preservação local entre 1982 e 2008. Concentra-se o foco nos discursos, embates e apropriações desencadeados a partir da aplicação dos instrumentos de preservação tombamento e registro em função dos conflitos e interesses que colocam em jogo. Visa identificar o que as modalidades de invenção discursivas do patrimônio juizforano presentes nos processos tem a dizer, e, permitem dizer, sobre a cidade de Juiz de Fora, bem como a categoria patrimônio de modo geral. De modo especifico procura investigar questões como: Qual a relação do patrimônio juizforano com o espaço urbano da cidade? Que narrativas e concepções de passados, história e patrimônios estão colocadas em jogo? Como são operadas as antinomias entre os ideólogos do patrimônio local e os agentes do mercado; entre narrativas do passado e da memória contrapostas às narrativas de progresso; entre direito público e privado? Como a categoria patrimônio é formulada e desliza em meio à tais questões?

Inhibition of the myotoxic activity of Bothrops jararacussu venom and its two major myotoxins, BthTX-I and BthTX-II, by the aqueous extract of Tabernaemontana catharinensis A. DC. (Apocynaceae)

Partial neutralization of the myotoxic effect of Bothrops jararacussu venom (BV) and two of its myotoxins [bothropstoxin-I (BthTX-I), catalytically inactive, and II (BthTX-II), showing low PLA(2) activity], by the lyophilized aqueous extract of Tabernaemontana catharinensis (AE), was studied in rat isolated soleus muscle preparations (in vitro) and through i.m. injection in the gastrocnemius muscle (in vivo) by determination of creatine kinase (CK) activity and histopathological analysis. Incubation of soleus muscle for 1 h with BV or toxins (20 mug/ml) plus AE (400 mug/ml) added immediately after BV, BthTX-I or BthTX-II reduced CK levels by 53%, 37% and 56%, respectively. The myonecrotic effects of BV (20 mug/ml) upon soleus muscle was reduced 24%, 35% and 36% when AE (400 mug/ml) was added 1 h after BV and CK was evaluated 30 min, 1 and 2 h later, respectively. For BthTX-I these values were 46%, 48% and 47%, while for BthTX-II no inhibitory effect was detected. Histological analysis of soleus muscle after incubation with AE (400 mug/ml, I h) did not reveal any change in muscle fibers, but severe necrosis induced by -BV or toxins (20 mug/ml) was clearly in evidence, and decreased significantly when soleus muscle was protected by AE. This protection was also observed when AE was administered 1 h after BV or BthTX-I, but not after BthTX-II. AE did not inhibit the catalytic PLA(2), activity of BthTX-II or BV and did not change the PAGE pattern of BV, BthTX-I or BthTX-II. In vivo assays were performed in 100-g rats and maximal CK release was attained at a dose of 100 mug of BV, 3 h after injection. AE was not effective when injected 20 s after BV or toxins. However, injecting BV or toxins (100 mug), which were pre-incubated with AE (2 mg) caused an inhibition of 57%, 59% and 51%, respectively, with zero time pre-incubation, but was less effective with I h pre-incubation. This plant represents a potential source of promising myotoxin inhibitors. (C) 2004 Elsevier GmbH. All rights reserved.

Optimisation of environmental gas cleaning routes for solid wastes cogeneration systems - Part I - Analysis of waste incineration steam cycle

Research of advanced technologies for energy generation contemplates a series of alternatives that are introduced both in the investigation of new energy sources and in the improvement and/or development of new components and systems. Even though significant reductions are observed in the amount of emissions, the proposed alternatives require the use of exhaust gases cleaning systems. The results of environmental analyses based on two configurations proposed for urban waste incineration are presented in this paper; the annexation of integer (Boolean) variables to the environomic model makes it possible to define the best gas cleaning routes based on exergetic cost minimisation criteria. In this first part, the results for steam cogeneration system analysis associated with the incineration of municipal solid wastes (MSW) is presented. (c) 2007 Elsevier Ltd. All rights reserved.

Social support and infant malnutrition: a case-control study in an urban area of Southeastern Brazil

The relationship between malnutrition and social support was first suggested in the mid-1990s. Despite its plausibility, no empirical studies aimed at obtaining evidence of this association could be located. The goal of the present study was to investigate such evidence. A case-control study was carried out including 101 malnourished children (weight-for-age National Center for Health Statistics/WHO 5th percentile) aged 12-23 months, who were compared with 200 well-nourished children with regard to exposure to a series of factors related to their social support system. Univariate and multiple logistic regressions were carried out, odds ratios being adjusted for per capita family income, mother's schooling, and number of children. The presence of an interaction between income and social support variables was also tested. Absence of a partner living with the mother increased risk of malnutrition (odds ratio 2.4 (95 % CI 1.19, 4.89)), even after adjustment for per capita family income, mother's schooling, and number of children. The lack of economic support during adverse situations accounted for a very high risk of malnutrition (odds ratio 10.1 (95 % CI 3.48, 29.13)) among low-income children, but had no effect on children of higher-income families. Results indicate that receiving economic support is an efficient risk modulator for malnutrition among low-income children. In addition, it was shown that the absence of a partner living with the mother is an important risk factor for malnutrition, with an effect independent from per capita family income, mother's schooling, and number of children.

Serology for Brucella abortus in cart horses from an urban area in Brazil

Avaliou-se a infecção por Brucella abortus em cavalos de carroça de Curitiba e São José dos Pinhais-PR. Um total de 123 amostras foi submetido ao teste do antígeno tamponado acidificado (ATA), soroaglutinação lenta em tubos (SAL) e prova do 2-mercaptoetanol (2-ME) para confirmação dos resultados. Oito (6,5%) equinos foram positivos para o ATA e um animal permaneceu positivo ao teste confirmatório. Existem evidências da presença de brucelose entre os cavalos de carroça.

Paralyzing and myotoxic effects of a recombinant bothropstoxin-1 (BthTX-I) on mouse neuromuscular preparations

As a first step to investigate the structure-function relationship of bothropstoxin-1 (BthTX-1), a myotoxin from Bothrops jararacussu snake venom, Our group previously cloned a recombinant toxin (rBthTX-1) in Escherichia coli. The aim or this work was to characterize the biological activities of this rBthTX-1 (1.0 mu M) in both phrenic-diaphragm and extensor digitorum longus preparations in vitro, by means of myographic and morphologic techniques. Native BthTX-1 (1.0 mu M) was used as a standard. The influence of heparin (27.5 mu g/ml) upon the biological activities of both toxins was also investigated. rBthTX-1 had similar effects to the native toxin inducing blockage of both directly and indirectly evoked contractions in phrenic-diaphragm preparations, and muscle damage characterized by edema, round fibers, and cell areas devoid of myofibrils. Interestingly the paralyzing activity of rBthTX-1 was slightly more potent than the native toxin. Heparin prevented paralyzing and myotoxic effects of both the native and recombinant toxins. This work shows that rBthTX-1 was expressed in a fully active form, and presents a biological profile similar to the native toxin. (c) 2005 Elsevier GmbH All rights reserved.
