Abstract: artificial reefs (ars) are becoming a popular biological and management component in shallow water environments characterized by soft seabed, representing both important marine habitats and tools to manage coastal fisheries and resources. because of the unstable nature of sediments, they require a detailed and systematic investigation that acoustic systems can provide. an ar into the marine environment acts as an open system with exchange of material and energy, altering the physical and biological characteristics of the surrounding area. the ar stability will depend on the balance of scour, settlement, and burial resulting from ocean conditions over time. the acoustic systems are efficient tools in monitoring the environmental evolution around ars, whereas water turbidity can limit visual dive and rov inspections. high-frequency multibeam echosounder offers the potential of detecting fine-scale distribution of reef units, providing an unprecedented level of resolution, coverage, and spatial definition. in 2008 the em3002 multibeam was used to investigate the first scientifically-planned ar in italy deployed during 1974-75. after 33 years the ar is almost in perfect condition. a considerable scouring around the structures and some vertical/horizontal movements of the single units have occurred. moreover a deepening of the whole area hosting the ar was observed.

Abstract: Artificial reefs (ARs) are becoming a popular biological and management component in shallow water environments characterized by soft seabed, representing both important marine habitats and tools to manage coastal fisheries and resources. Because of the unstable nature of sediments, they require a detailed and systematic investigation that acoustic systems can provide. An AR into the marine environment acts as an open system with exchange of material and energy, altering the physical and biological characteristics of the surrounding area. The AR stability will depend on the balance of scour, settlement, and burial resulting from ocean conditions over time. The acoustic systems are efficient tools in monitoring the environmental evolution around ARs, whereas water turbidity can limit visual dive and ROV inspections. High-frequency multibeam echosounder offers the potential of detecting fine-scale distribution of reef units, providing an unprecedented level of resolution, coverage, and spatial definition. In 2008 the EM3002 multibeam was used to investigate the first scientifically-planned AR in Italy deployed during 1974-75. After 33 years the AR is almost in perfect condition. A considerable scouring around the structures and some vertical/horizontal movements of the single units have occurred. Moreover a deepening of the whole area hosting the AR was observed. Os recifes artificiais (ARs) est o se tornando um componente biológico e de manejo de ambientes de áreas rasas com substratos característicos n o rígidos, representando habitats marinhos importantes e ainda constituindo uma ferramenta para o manejo da pesca e dos recursos costeiros. Devido à natureza instável dos sedimentos, exigem um estudo detalhado e sistemático que os sistemas acústicos podem disponibilizar. Um RA atua no ambiente marinho como um sistema aberto com troca de materiais e energia, alterando as características físicas e biológicas das áreas que o cerca. A estabilidade do RA dependerá do equilíbrio entre a escava o, o assentamento e aterramento resultantes das a es do oceano no decorrer do tempo. Os sistemas acústicos s o ferramentas eficientes no monitoramento da evolu o ambiental ao redor dos ARs, uma vez que a turbidez da água pode limitar o mergulho visual e as inspe es ROV. A ecosonda multifeixe de alta frequência oferece meios para identificar com precis o a distribui o das unidades recifais, com nível de resolu o, cobertura e defini o especial. Em 2008, a sonda multifeixe EM3002 foi usada para estudar a primeira implanta o cientificamente planejada de RA na Itália,
Overview on artificial reefs in Europe
Gianna Fabi,Alessandra Spagnolo,Denise Bellan-Santini,Eric Charbonnel
Brazilian Journal of Oceanography , 2011,
Abstract: Artificial reefs in Europe have been developed over the last 40 yrs. Most of these reefs have been placed in the Mediterranean Sea, but there is an increasing interest on the part of northern European countries. Fish stock enhancement and fishery management are the main purposes of reef construction in the Mediterranean Sea and on the Atlantic coast of the Iberian Peninsula, while nature conservation/restoration, research, and recreation have been the main purposes served in the other European regions to date. Artificial reef deployment falls under some general regulations concerning the protection of the sea against pollution due to the dumping of unsuitable materials. Specific Regional Plans relating to the use of artificial reefs in the marine environment and Guidelines for reef construction have been derived from these general regulations. In spite of recent developments, national and/or regional programs for the deployment of artificial reefs and/or their inclusion in overall management plans for integrated management of coastal zones are in force only in the majority of Mediterranean countries, while only a few projects have, to date, been undertaken in the other European Regions. Moreover, there is a noteworthy lack of plans, in many countries, for the management of the reefs after their deployment. Os recifes artificiais, na Europa, foram desenvolvidos nos últimos 40 anos. A maioria desses recifes foram instalados no Mar Mediterraneo, mas despertam um interesse crescente por parte dos paises do norte europeu. O incentivo aos estoques pesqueiros e o manejo da pesca s o os principais objetivos da constru o de recifes no Mar Mediterraneo e na costa Atlantica da Península Ibérica, enquanto a preserva o / recupera o da natureza, a pesquisa e a recrea o tem sido os principais objetivos das demais regi es européias até hoje. A implanta o de recifes artificiais está submetida a algumas regulamenta es básicas quanto à prote o dos oceanos com rela o à polui o devido ao despejo de materiais. Projetos Regionais específicos relativos ao uso de recifes artificiais no ambiente marinho e Instru es para a constru o de recifes s o decorrentes dessa Regulamenta o Geral. Apesar de avan os recentes, programas regionais e/ou nacionais sobre a instala o de recifes artificiais e/ou a sua inclus o nos planos gerais de planejamento para a gest o integral das zonas costeiras tem mais destaque somente em grande parte dos paises do Mediterraneo, enquanto que, poucos projetos até hoje tem sido realizados nas outras Regi es Européias.

Orthodox Church and Science Education Policy in Modern Greece  [PDF]
Gianna Katsiampoura
Advances in Historical Studies (AHS) , 2019, DOI: 10.4236/ahs.2019.82007
Abstract: The aim of this paper is to present the influence the Greek Orthodox Church has on matters of Education Policy in the Modern Greek state, especially on Science Education. Historically, since its foundation, the Greek state is closely linked to the Orthodox Church, which is the institution of orthodox Christianity, the official religious dogma of the Greek state as it is explicitly mentioned in the Greek Constitution. Since the foundation of the Modern Greek state, nearly two centuries ago, the Orthodox Church plays a key role in every aspect of general policy, and especially in educational policy. It is characteristic that religious affairs and education are governed by the same ministry, the Ministry of Education, Research and Religions, and orthodox priests are public employees enjoying the status of civil servants. Historically, this interlink of the Church with the State can be easily explained by the privileged relation the patriarch had with the sultan in the Ottoman empire, a status that continued to exist in a different form in the epoch of the Modern Greek state. Due to its privileged position in the state apparatus, the Orthodox Church and its multitude of official and unofficial organizations could control the educational policy and especially the national curriculum. This control is more obvious in science education. The aim of this paper is to present the influence the Greek Orthodox Church has on matters of secular education policy in the Modern Greek state, especially on the curriculum of natural sciences. Here, we don’t refer to the parallel secondary education system organized by the Church, which is another point of confrontation between the Greek Orthodox Church and the Greek state in several occasions.
Comparison of growth rates estimated by otolith reading of Scorpaena porcus and Scorpaena notata caught on artificial and natural reefs of the northern Adriatic sea
Scarcella, Giuseppe;Grati, Fabio;Polidori, Piero;Domenichetti, Filippo;Bolognini, Luca;Fabi, Gianna;
Brazilian Journal of Oceanography , 2011,
Abstract: despite the high number of studies on fish assemblages associated with artificial reefs and offshore platforms, little information exists on the growth rates of fish living on artificial and natural substrates. age and growth was determined throughout otolith reading on two commercial scorpionfishes (scorpaena porcus and scorpaena notata) caught in the surroundings of artificial structures (artificial reefs and gas platforms) and natural habitats. von bertalanffy growth parameters were calculated for each species separately for each site. age of s. porcus and s. notata ranged from 0 to 8 years and from 0 to 16 years, respectively. kimura test applied to von bertalanffy growth curves indicated that the individuals of both species inhabiting the artificial structures had higher growth parameters than those caught in the natural habitat. the presence of artificial habitats in the northern adriatic sea positively affects growth rates and growth performance of both species, likely for the greater prey availability in respect to the natural open sea.

Analisi critica vs. produzione creativa. Le nuove sfide della media education nell’era digitale
Gianna Cappello
Form@re : Open Journal per la Formazione in Rete , 2013,
Abstract: Il consumo dei media è ingrediente di base della vita pubblica e privata dei minori rivestendo un ruolo fondamentale nella costruzione della loro identità e socialità. Una dimensione cruciale delle loro esperienze mediali è costituita dal piacere e dal gioco. In questo contributo si vuole sostenere che se l’educazione formale non riconosce questo ruolo e questa dimensione, il suo divario con i mondi vitali dei ragazzi fuori dalla scuola è destinato ad allargarsi sempre più. L’introduzione della media education1 può ridurre questo divario, a condizione però che l’analisi critica venga combinata alla produzione creativa degli studenti in classe, e cioè aprendo uno spazio dove questi ultimi possono esplorare gli aspetti piacevoli delle loro esperienze mediali quotidiane e al tempo stesso affrontare criticamente la loro condizione di consumatori e cittadini nella cultura contemporanea e capire i modi in cui i piaceri che derivano dai media sono socialmente costruiti.

Gender: Italian Perspectives on a Useful Category for Comparative Literature
Gianna Fusco
Trans : Revue de Littérature Générale et Comparée , 2006,
Abstract: Cet article trace des liens, sur les plans théorique et critique, entre le domaine de la littérature comparée et la catégorie des gender studies. Ces liens sont examinés en tenant compte de leurs développements actuels au sein de l’université italienne, avec un regard spécifique sur le caractère multi- et interdisciplinaire de nombreuses contributions qui s’inscrivent dans le cadre de ce débat. This essay traces the connections, both on a theoretical and on a critical level, between the field of comparative literature and the category of gender studies. These connections will be analyzed in the context of the Italian academy, with specific regard to the multi- and interdisciplinary character of many contributions to the debate. Tanto en el plano teórico como en el crítico, el presente artículo establece vínculos entre el campo de la literatura comparada y el área de los cultural studies. Tales vínculos son examinados según el desenvolvimiento de cada disciplina en la universidad italiana de hoy, poniendo un especial interés en el carácter multi- e interdisciplinario de numerosas contribuciones que se inscriben dentro de los límites del debate.
