The current approval procedure for wind farm proposals in the German EEZ only considers site specific conflict analysis between the wind farm and fisheries. Due to the relatively small spatial coverage of single sites potential opportunity losses to the fisheries are always considered as low or negligible. Cumulative effects on fisheries that will occur once all proposed wind farms are in place are not yet considered adequately. However, those cumulative effects will be quite substantial because, in particular, opportunities to catch such valuable species as flatfish will be considerably reduced.

A presente tese se empenha na análise comparada de corte polanyiano da trajetória de liberalização econômica do Brasil e Índia. O objetivo é compreender os padrões de mudança institucional que organizam as reformas orientadas para o mercado. Para isso empregou uma análise que combina modelos de coalizão de interesse, dependência de trajetória e comunidades epistêmicas empregados de forma interdependente para entender as adaptações ao cenário de globalização financeira. Os mecanismos de fertilização mútua dessas variáveis causais desempenham um papel analítico crucial porque permitiu escapar de modelos monocausais que tendem a ficar presos a explicações que sobredeterminam exclusivamente restrições externas, padrões institucionais domésticos ou legados institucionais estatais. Ao empregar esse instrumento, a tese procura mostrar as diferenças no grau de liberdade das capacidades estatais entre Brasil e Índia no contexto das reformas e as semelhanças em termos da estratégia incremental das reformas.

The impact of transient wind events on an established zooplankton community was observed during a, field survey in a, coastal region off northern Norway in May 2002. A transient wind event induced a coastal jet/filament intrusion of warm, saline water into our survey area where a semi-permanent eddy was present. There was an abrupt change in zooplankton community structure within 4-7 days of the wind event, with a change in the size structure, an increase in lower size classes less than 1 mm in equivalent spherical diameter (ESD) and a decrease in larger size classes greater than 1.5 mm in ESD. The slope of zooplankton biovolume spectra changed from -0.6 to -0.8, consistent with the size shifting towards smaller size classes. This study shows that even well established zooplankton communities are susceptible to restructuring during transient wind events, and in particular when wind forcing induces horizontal currents or filaments.

Efficient early identification of primary immunodeficiency disease (PID) is important for prognosis, but is not an easy task for non-immunologists. The Clinical Working Party of the European Society for Immunodeficiencies (ESID) has composed a multi-stage diagnostic protocol that is based on expert opinion, in order to increase the awareness of PID among doctors working in different fields. The protocol starts from the clinical presentation of the patient; immunological skills are not needed for its use. The multi-stage design allows cost-effective screening for PID within the large pool of potential cases in all hospitals in the early phases, while more expensive tests are reserved for definitive classification in collaboration with an immunologist at a later stage. Although many PIDs present in childhood, others may present at any age. The protocols presented here are therefore aimed at both adult physicians and paediatricians. While designed for use throughout Europe, there will be national differences which may make modification of this generic algorithm necessary.
