Il massiccio di Beni Bousera (Marocco) è formato da diverse unità geologiche composte prevalentemente da rocce metamorfiche molto simili a quelle che si trovano nel massiccio di Ronda (Spagna). Queste due catene montuose erano connesse prima dell’estensione (iniziata nel Miocene inferiore) che le ha separate lasciando il posto al mare di Alborán. Questo studio sarà incentrato soltanto sul massiccio marocchino, in particolare sull’unità peridotitica di Beni Bousera. Questa unità è stata suddivisa in quattro domini, ognuno dei quali ha specifiche caratteristiche petrologiche e geochimiche, che sono il risultato di diverse condizioni metamorfiche e di diversi regimi tettonici. L’obiettivo di questo lavoro è di caratterizzare, dal punto di vista petrologico, un campione che è stato prelevato dal massiccio di Beni Bousera, nella zona costiera del mare di Alborán e di determinare a quale dominio esso appartiene.

Macro- and meiobenthic abundance and biomass as well as metabolic activity (respiration, ETS activity) have been studied along a transect ranging from 130 to 3000 m water depth off northern Morocco (35° N) during "Meteor" cruise No. 53 (1980). The distribution of chloroplastic pigment concentration (chlorophyll a, pheophytins) in the sediment has been investigated as a measure of sedimented primary organic matter. High chloroplastic pigment concentrations were found on the shelf and around the shelf break, but values declined rapidly between 200 and 600 m depth. Below 1200 m pigment concentrations remained at a relatively uniform low level. Macrobenthic abundance and biomass (wet weight) decreased with increasing water depth and with distance from the shore. Significant changes occurred between the shelf and upper slope and below 2000 m depth. Meiobenthic abundance and biomass (ash free dry weight) followed the same general pattern, but changes were found below 400 and 800 m depth. In the depth range of 1200 to 3000 m values differ only slightly. Meiofauna abundance and biomass show a good correlation with the sedimentary chloroplastic pigment concentrations. Respiratory activity of sediment cores, measured by a shipboard technique at ambient temperatures, decreased with water depth and shows a good correlation with the pigment concentrations. ETS activity was highest on the shelf and decreased with water depth, with significant changes between 200 and 400 m, and below 1200 m depth, respectively. Activity was generally highest in the top 5 cm of the sediment and was measurable, at all stations, down to 15 cm sediment depth. Shelf and upper slope stations exhibited a vertical distribution pattern of ETS activity in the sediment column, different from that of deeper stations. The importance of biological activity measurements as an estimate of productivity is discussed. To prove the thesis that differences in benthic abundance, biomass and activity reflect differences in pelagic surface primary production, in the case of the NW-African coast caused by different upwelling intensities, the values from 35° N were compared with data from 21° N (permanent upwelling activity) and 17° N (ca. 9 months upwelling per year). On the shelf and upper slope (< 500 m) hydrographical conditions (currents, internal waves) influence the deposition of organic matter and cause a biomass minimum between 200 and 400 m depth in some regions. But, in general, macrobenthic abundance and biomass increases with enhanced upwelling activity and reaches a maximum in the area off Cape Blanc (21° N). On the shelf and in the shelf break region meiofauna densities are higher at 35° N in comparison to 21° N; but in contrast to the decreasing meiofauna abundance with increasing water depth at 35° N, an abundance maximum between 400 and 1200 m depth is formed in the Cape Blanc region; this maximum coincides with the maximum of sedimentary chloroplastic pigment equivalents. The comparison of ETS activities between 35° N and 21° N shows on the shelf activity at 21° N is up to 14 times higher and on the slope 4-9 times higher, which demonstrates that benthic activity responds to the surface productivity regime.

The influence of different primary productivity regimes on live (Rose Bengal stained) and dead benthic foraminiferal distribution, as well as on the stable carbon isotopic composition of foraminiferal tests, was investigated in sediment surface samples (0-1 cm) from the upwelling region off Morocco between Cape Ghir (31°N) and Cape Yubi (27°N). A combination of factor analysis, detrended correspondence analysis (DCA) and canonical correspondence analysis (CCA) was applied to the benthic foraminiferal data sets. Five major assemblages for both the live and dead fauna were revealed by factor analysis. In the cape regions organic matter fluxes are enhanced by high chlorophyll-a concentrations in the overlying surface waters. Here, benthic foraminiferal faunas are characterized by identical live and dead assemblages, high standing stocks, and low species delta13C values, indicating constant year-round high productivity. Bulimina marginata dominates the unique fauna at the shallowest station off Cape Ghir indicating highest chlorophyll-a concentrations. Off both capes, the succession of the Bulimina aculeata/Uvigerina mediterranea assemblage, the Sphaeroidina bulloides/Gavelinopsis translucens assemblage, and the Hoeglundina elegans assemblage from the shelf to the deep sea reflects the decrease in chlorophyll-a concentrations, hence the export flux. In contrast, the area between the capes is characterized by differently composed live and dead assemblages, low standing stocks, and less depleted delta13C values, thus reflecting low primary productivity. High foraminiferal numbers of Epistominella exigua, Eponides pusillus, and Globocassidulina subglobosa in the dead fauna indicate a seasonally varying primary productivity signal. Significantly lower mean delta13C values were recorded in Bulimina mexicana, Cibicidoides kullenbergi, H. elegans, U. mediterranea and Uvigerina peregrina. Cibicidoides wuellerstorfi is a faithful recorder of bottom water delta13C in the Canary Islands regions. The mean delta13C signal of this species is not significantly influenced by constant high organic matter fluxes. The species-specific offset between live and dead specimens is the same.

In theory, the multiple platforms and transnational nature of digital media, along with a related proliferation of diverse forms of content, make it easier for children’s right to access socially and culturally beneficial information and material to be realised, as required by Article 17 of the UN Convention on the Rights of the Child (CRC). Drawing on data collected during research on children’s screen content in the Arab world, combined with scrutiny of documents collated by the Committee on the Rights of the Child, which monitors compliance with the CRC, this paper explores how three Arab countries, Egypt, Morocco and the United Arab Emirates, presented their efforts to implement Article 17 as part of their periodic reporting on their overall performance in putting the CRC into effect. It uncovers tensions over the relationship between provision, participation and protection in relation to media, reveals that Article 17 is liable to get less attention than it deserves in contexts where governments keep a tight grip on media, and that, by appearing to give it a lower priority, all parties neglect the intersection between human rights in relation to media and children’s rights.

This paper describes research carried out as part of a wider doctoral study on ‘the biography of music teachers, their understanding of musicality and the implications for secondary music education’. Music teachers will come from a range of diverse backgrounds, though research data would suggest that most seem to have been educated as ‘classical’ music performers which will have an affect on what they perceive to be central competencies in the development of young musicians. In turn, this will determine, to some extent, what is taught and learned in the secondary music classroom. This study explores the impact of the biography of secondary music teachers as they seek to develop the musicianship of their pupils and present the activities in which the young people will be expected to participate. A mixed methods approach has been taken, including surveys, observation and interviews. Surveys amongst a sample of experienced and trainee teachers have produced a range of quantitative data on respondents’ experience of and values related to music education; whilst qualitative data in the form of lesson observation notes and transcription of semi-structured interviews have been the result of working with a small sub-set of participants. The outcomes of study have suggested a clear link between biography and classroom practice but that there are also other potential tensions which arise, such as in the subject knowledge development of practitioners as they move from musician to teacher. Implications for a variety of stakeholders in secondary music education include a consideration of the development of subject knowledge together with potential review of national and local education policy, the nature of undergraduate music study and the ‘shape’ of initial teacher training in England.
