Struggling for recognition and inclusion—parents' and pupils' experiences of special support measures in school

During the last decade an increasing use of differentiated support measures for pupils with special educational needs, indicative of a discrepancy between educational policies and practices, has been witnessed in Sweden. Another trend has been the increased use of medical diagnoses in school. The aim of this study was to explore the main concern of support given to pupils with special educational needs and how pupils and parents experience and handle this. Interviews were conducted with eight pupils in Grades 7–9—and their parents—at two compulsory schools in a city in northern Sweden. A grounded theory approach was used for analyzing the interview data. A conceptual model was generated illuminating the main concern of special support measures for pupils and parents. The core category of the model, struggling for recognition and inclusion, was related to two categories, which further described how this process was experienced and handled by the participants. These categories were labeled negotiating expertise knowledge within a fragmented support structure and coping with stigma, ambivalence, and special support measures. The developed conceptual model provides a deeper understanding of an ongoing process of struggle for recognition and inclusion in school as described by the pupils and parents

The Biodiversity of the Mediterranean Sea: Estimates, Patterns, and Threats

The Mediterranean Sea is a marine biodiversity hot spot. Here we combined an extensive literature analysis with expert opinions to update publicly available estimates of major taxa in this marine ecosystem and to revise and update several species lists. We also assessed overall spatial and temporal patterns of species diversity and identified major changes and threats. Our results listed approximately 17,000 marine species occurring in the Mediterranean Sea. However, our estimates of marine diversity are still incomplete as yet—undescribed species will be added in the future. Diversity for microbes is substantially underestimated, and the deep-sea areas and portions of the southern and eastern region are still poorly known. In addition, the invasion of alien species is a crucial factor that will continue to change the biodiversity of the Mediterranean, mainly in its eastern basin that can spread rapidly northwards and westwards due to the warming of the Mediterranean Sea. Spatial patterns showed a general decrease in biodiversity from northwestern to southeastern regions following a gradient of production, with some exceptions and caution due to gaps in our knowledge of the biota along the southern and eastern rims. Biodiversity was also generally higher in coastal areas and continental shelves, and decreases with depth. Temporal trends indicated that overexploitation and habitat loss have been the main human drivers of historical changes in biodiversity. At present, habitat loss and degradation, followed by fishing impacts, pollution, climate change, eutrophication, and the establishment of alien species are the most important threats and affect the greatest number of taxonomic groups. All these impacts are expected to grow in importance in the future, especially climate change and habitat degradation. The spatial identification of hot spots highlighted the ecological importance of most of the western Mediterranean shelves (and in particular, the Strait of Gibraltar and the adjacent Alboran Sea), western African coast, the Adriatic, and the Aegean Sea, which show high concentrations of endangered, threatened, or vulnerable species. The Levantine Basin, severely impacted by the invasion of species, is endangered as well

Effects of summer ice coverage on phytoplankton assemblages in the Ross Sea, Antarctica.

An oceanographic cruise was conducted in the Ross Sea (Antarctica) during summer 2001 as part of the Italian National Program for Antarctic Research (PNRA). Extensive areas of pack ice occurred over the Ross Sea, atypical for summer when offshore waters are normally free of ice. The present study focuses on the effects of increased ice coverage on phytoplankton assemblages. Water samples collected at various depths at 72 hydrographical stations in offshore and coastal waters were used to determine size-fractionated phytoplankton biomass as chlorophyll a (chla) concentrations, and HPLC photosynthetic pigments. For the offshore waters, the average chla concentration was 57.8mgm-2, approximately three times the values recorded under ice-free conditions during summer 1996. In coastal waters, the average chla concentrations were 102 and 206mgm-2 during January and February, respectively, i.e., up to 2.5 times those of 1996. Micro- and nano-phytoplankton size fractions made up about 90% of the phytoplankton biomass over the entire study area and were composed primarily of diatoms with a pico-phytoplankton fraction dominated by prymnesiophyceans. The broken pack and melting ice was strongly coloured by an extensive algal biomass suggesting that the phytoplankton was a result of seeding from ice algal communities. The Ross Sea considered to be one of the most productive areas of the Southern Ocean, had primary production values about four-fold those of other areas. The lengthening of the ice season observed in the Western Ross Sea, associated with a considerable increase in phytoplankton biomass as observed in summer 2001, would have a major impact on the trophic structure of the entire ecosystem, and presumably, also on carbon export
