The effects of a soft drink tax in the UK

The majority of the UK population is either overweight or obese. Health economists, nutritionists and doctors are calling for the UK to follow the example of other European countries and introduce a tax on soft drinks as a result of the perception that high intakes contribute to diet-related disease. We use a demand model estimated with household-level data on beverage purchases in the UK to investigate the effects of a tax on soft drink consumption. The model is a Quadratic Almost Ideal Demand System, and censoring is handled by applying a double hurdle. Separate models are estimated for low, moderate and high consumers to allow for a differential impact on consumption between these groups. Applying different hypothetical tax rates, we conclude that understanding the nature of substitute/complement relationships is crucial in designing an effective policy as these relationships differ between consumers depending on their consumption level. The overall impact of a soft drink tax on calorie consumption is likely to be small.

Statistical-dynamical downscaling for wind energy potentials: evaluation and applications to decadal hindcasts and climate change projections

A statistical–dynamical downscaling (SDD) approach for the regionalization of wind energy output (Eout) over Europe with special focus on Germany is proposed. SDD uses an extended circulation weather type (CWT) analysis on global daily mean sea level pressure fields with the central point being located over Germany. Seventy-seven weather classes based on the associated CWT and the intensity of the geostrophic flow are identified. Representatives of these classes are dynamically downscaled with the regional climate model COSMO-CLM. By using weather class frequencies of different data sets, the simulated representatives are recombined to probability density functions (PDFs) of near-surface wind speed and finally to Eout of a sample wind turbine for present and future climate. This is performed for reanalysis, decadal hindcasts and long-term future projections. For evaluation purposes, results of SDD are compared to wind observations and to simulated Eout of purely dynamical downscaling (DD) methods. For the present climate, SDD is able to simulate realistic PDFs of 10-m wind speed for most stations in Germany. The resulting spatial Eout patterns are similar to DD-simulated Eout. In terms of decadal hindcasts, results of SDD are similar to DD-simulated Eout over Germany, Poland, Czech Republic, and Benelux, for which high correlations between annual Eout time series of SDD and DD are detected for selected hindcasts. Lower correlation is found for other European countries. It is demonstrated that SDD can be used to downscale the full ensemble of the Earth System Model of the Max Planck Institute (MPI-ESM) decadal prediction system. Long-term climate change projections in Special Report on Emission Scenarios of ECHAM5/MPI-OM as obtained by SDD agree well to the results of other studies using DD methods, with increasing Eout over northern Europe and a negative trend over southern Europe. Despite some biases, it is concluded that SDD is an adequate tool to assess regional wind energy changes in large model ensembles.

Trust in the German police

The relative levels of trust in the police are explored, using data from the fifth round of the European Social Survey (ESS) which covered mainly 28 European countries. In this article, the position of Germany is examined within the international context. German trust in the police, for both German natives and ethnic minorities, for those 15 and over is high in comparison to other European countries. The article also tests if it is the fair treatment of citizens by the police, or the high value placed on rule adherence and conformity, that is driving the German citizen’s trust. It shows that the German police is trusted due to their perceived fairness, effectiveness and shared moral values, rather than on value placed on conformity to authority.

Borlänge and Falun Brundtland cities

Development of an infrastructure for Brundtland Renewable Energy Network - BREN is a European Commission Alterner Project with Contract no XVII/4. 1030/Z96-032.The project has its origin in the UN-report “Our Common Future”, 1989. A change in and reduction of the use of energy was fundamental in order to reach the goals which the report proposed. Denmark decided on an action plan on how energy consumption could be reduced “Energi 2000 - Handlingsplan för en bäredygtig udvikling”. The ministries of energy in Denmark and Schleswig Holstein both agreed to start an energy saving project in a smaller town. The project was called “Brundtlandby” and the two first were Toftlund in South Jutland and Bredstedt in North Friesland. After a short period a further two German Cities, Rheinsberg and Viernheim, and Rajec in Slovakia joined the group. A network for the exchange of knowledge and experience between the cities was formed. The network, Brundtland City Project, inspired the participating cities in the continuing work with energy saving measures. The Brundtland City Project was presented at an international conference “Cities and Energy” in Trondheim, Norway,in December 1995. Great interest was shown in the project and it was decided that a network should be developed in northern European countries as a pilot project to be enlarged with other European countries later on. A steering committee was formed with representatives from the nordic countries.An application was sent to the European Commission, Alterner Program, and was approved in Juli 1996. The project was subdivided into nine activities. Activity 1, consisted of summarising the experiences of the Brundtland City Project in Toftlund, Denmark and the Brundtland Cities network in Slovakia, Germany and Denmark. The Scandinavian part started with Activity 2, to engage municipalities/cities in Finland, Norway and Sweden in the project. The Solar Energy Research Center, SERC, Högskolan Dalarna was appointed as co-ordinator for the Swedish part. The project was presented at a seminar on the 30th September for representatives from the municipalities of Borlänge and Falun. On the 10th of December 1996 the two municipalities accepted the invitation to join the Northern network. Pelle Helje, Borlänge Energi, has been informant for the municipality of Borlänge and Anders Goop, Department of Urban Planninginformant for the municipality of Falun with Jan Kaans, Estates department providing information to the basis for the Newsletter.Reports on the work in Borlänge and Falun municipalities have been made to Brundtland Center Denmark on three occasions; Activities 2-5, 16-12-1997, Activities 6-7, including parts of activities 8-9, 03-03-1998, and the basis for the Newsletter, 01-07-1998. The Nordic reports have been compiled at the Brundtland Center Denmark for submission to the European Commission. English has been the common language. After the report of activities 2 - 5 the participants wereinvited to a project meeting and a workshop at Brundtland Center the 23rd and 24th March 1998.This was the first occasion the participants in the project met and the network thus took a moreconcrete form. It also was decided that the next meeting should be in Borlänge in August 1998,with Borlänge Energi and Solar Energy Research Center SERC as organisers. As BrundtlandCentre Denmark was wound up for financial reasons, the project meeting in Borlänge wascancelled.Compilation of the Final Report was carried out by Esbensen Consultants in October 1998Future development of the networkIt is intended to continue the work with the Brundtland City Network as an “EU Thermie Bproject”and the network will be enlarged with the addition of four new Brundtland Cities from Austria, Germany, Italy and Great Britain. In addition the village of Putja in Estonia will join the network but this will be financed by the EU-Phare programme.

Methods and background characteristics of the TOHNN study : a population-based study of oral health conditions in northern Norway

OBJECTIVES: The aim of the Tromstannen - Oral Health in Northern Norway (TOHNN) study was to investigate oral health and dental-related diseases in an adult population. This article provides an overview of the background of the study and a description of the sample characteristics and methods employed in data collection. STUDY DESIGN: Cross-sectional population-based study including a questionnaire and clinical dental examination. METHODS: A randomly selected sample of 2,909 individuals (20-79 years old) drawn from the population register was invited to participate in the study. The data were collected between October 2013 and November 2014 in Troms County in northern Norway. The questionnaire focused on oral health-related behaviours and attitudes, oral health-related quality of life, sense of coherence, dental anxiety and symptoms from the temporomandibular joint. The dental examinations, including radiographs, were conducted by 11 dental teams in 5 dental offices. The examination comprised of registration of dental caries, full mouth periodontal status, temporomandibular disorders, mucosal lesions and height and weight. The participants were grouped by age (20-34, 35-49, 50-64 and 65-79) and ethnicity (Norwegian, Sámi, other European and other world). RESULTS: From the original sample of 2,909 individuals, 1,986 (68.3%) people participated, of whom 1,019 (51.3%) were women. The highest attendance rate was among women 20-34 years old (80.3%) and the lowest in the oldest age group of women (55.4%). There was no difference in response rate between rural and urban areas. There was a positive correlation between population size and household gross income (p < 0.001) and education level (p < 0.001). The majority of Sámi resided in smaller municipalities. In larger cities, most participants used private dental health care services, whereas, in rural areas, most participants used the public dental health care service. CONCLUSION: The TOHNN study has the potential to generate new knowledge on a wide range of oral health conditions beneficial to the population in Troms County. Due to the high participation rate, generalization both nationally and to the circumpolar area ought to be possible.

O computador no ensino de lígnua inglesa no CEFET/RN

The present study has as goal to analyze the aplicability of the computational technology as mediator in the english-speaking teaching in the Centro Federal de Educação Tecnológica do Rio Grande do Norte-CEFET/RN. The object of study was centered in the use of the computer incorporated in the teaching of English by four institution groups. The research was ruled metodologically in the study of case, adopting a qualitative and quantitative boarding of interpretative-reflexive mark. We support ourselves on a bibliographical literature revision that cares of the use of the computational technology matter into the class-room, aiming an education new practice, regarding the current reality conceptions in what we live in the technological education. We also use a referencial for a pedagogical action, trying to offer subsidies for a practice that provides the knowledges generation through the interaction, aiming a subject reflexive and critical education. For materialization of this study, we used esrutuctured action, as interviews for the teachers and students, besides the observations of the dayly in class-room, in order to get the necessary datas for analysis. During this study, we oserved that the use of the computer, while pedagogical support instrument in the english-speaking teaching, has acted like mediator of the teaching-learning process. The results demonstrate use of the computer use has been each more a practice adopted by other institution languages teachers. The conclusions confirm the hypothesis showed at the beginning of the work and evidence that the teachers are warden of forming thinking, reflexive and critical subjects. For that, they need to be prepared to face situations in which they can take the pedagogical practice to tune with the technological advances, consequently providing an effective technological education

Estendendo CRefine para o suporte de táticas de refinamento

The use of increasingly complex software applications is demanding greater investment in the development of such systems to ensure applications with better quality. Therefore, new techniques are being used in Software Engineering, thus making the development process more effective. Among these new approaches, we highlight Formal Methods, which use formal languages that are strongly based on mathematics and have a well-defined semantics and syntax. One of these languages is Circus, which can be used to model concurrent systems. It was developed from the union of concepts from two other specification languages: Z, which specifies systems with complex data, and CSP, which is normally used to model concurrent systems. Circus has an associated refinement calculus, which can be used to develop software in a precise and stepwise fashion. Each step is justified by the application of a refinement law (possibly with the discharge of proof obligations). Sometimes, the same laws can be applied in the same manner in different developments or even in different parts of a single development. A strategy to optimize this calculus is to formalise these application as a refinement tactic, which can then be used as a single transformation rule. CRefine was developed to support the Circus refinement calculus. However, before the work presented here, it did not provide support for refinement tactics. The aim of this work is to provide tool support for refinement tactics. For that, we develop a new module in CRefine, which automates the process of defining and applying refinement tactics that are formalised in the tactic language ArcAngelC. Finally, we validate the extension by applying the new module in a case study, which used the refinement tactics in a refinement strategy for verification of SPARK Ada implementations of control systems. In this work, we apply our module in the first two phases of this strategy

História de uma completiva: origem e desenvolvimento do complemento oracional introduzido por se do português

O propósito deste trabalho é investigar o percurso histórico da oração completiva iniciada pela conjunção se do português, que também introduz, nessa e em outras línguas românicas, uma oração adverbial condicional. Com base em registros de filólogos e romanistas, demonstra-se que a similaridade existente entre essas orações é resultado de gramaticalização da oração condicional que, no latim, passou a funcionar como oração completiva, em razão da extinção das partículas interrogativas que passaram a ser substituídas pela conjunção condicional latina si. Como oração completiva, a oração com se submete-se à gramaticalização, integrando-se à oração matriz de um modo que, conforme proposta de Hopper e Traugott (1993) e de Lehmann (1988), é próprio a construções completivas. A forma que tem essa oração de se gramaticalizar, incorporando-se à oração matriz, é, entretanto, diferente do que é previsto ocorrer a uma completiva introduzida por que, uma diferença que se deve, sobretudo, ao significado hipotético que a completiva com se preserva de sua fonte histórica. Demonstra-se, por fim, que, do português arcaico ao português contemporâneo, a gramaticalização do complemento oracional introduzido por se não se configura em mudança diacrônica, já que essa gramaticalização é atestada desde períodos mais remotos, em textos do século XIV.

Aprendendo línguas estrangeiras in-tandem: histórias de identidades

A Pesquisa Narrativa de Clandinin & Connelly (2000) compreende a experiência humana como histórias vividas e contadas. Nesta abordagem qualitativa de pesquisa, os participantes contam histórias e os pesquisadores as recontam e as reconstroem por meio de narrativas acerca das experiências. Tendo este arcabouço metodológico como orientador de nossos procedimentos de pesquisa, neste artigo investigamos nossa experiência compartilhada de aprendizagem in-tandem do português e do italiano - no caso, uma experiência de oito meses por meio de um tandem face-a-face. Neste período, vivenciamos e coletamos dados acerca de nosso processo de aprender a língua um do outro: anotações de campo, mensagens reflexivas de e-mail trocadas durante o período e o conteúdo anotado durante as aulas. Ao reviver nossas histórias vividas durante aquele período, por meio da narrativa aqui apresentada, ressaltamos os elementos de identidade no nosso tandem que acreditamos estarem relacionados à aprendizagem. Também individuamos os elementos desencadeadores de identidade específicos deste contexto de aprendizagem.

Em defesa da categoria de voz média no português

A voz média representa uma categoria flexional das línguas clássicas indo-européias com a função de expressar estados de coisas que afetam o sujeito do verbo ou seus interesses. O português dispõe de um conjunto de predicados, formalmente identificados pelo uso anafórico e não-correferencial do pronome 'se', em que se sustenta a noção de diátese medial. Este trabalho pretende fornecer evidências formais, semânticas e tipológicas para postular uma distinção entre construções médias e reflexivo-recíprocas.

Scientific pedagogy at the end of the 19th century: Some readings and writings in the Portuguese debate

Through the text presented we intend to outline the debate that occurred in Portugal in the transition from the 19th to the 20th centuries. At the time, the imperatives of scientific development had reached education as a basis for the national prosperity. It was believed that Portugal had fallen behind in comparison to the other European countries because it was not capable of constructing a civilization directed by scientific criteria, through the expansion and spreading of culture. The debate over the extension of schools to increasingly broader segments of the population acquires a different meaning when the theorist of Education make use of language from several other areas of knowledge in order to create a mosaic of what has become known, since that time, as the Science of Education.
