DELL’ANGELO, BRUNO, SANDRO GORI, LEONARDO BASCHIERI et ANTONIO BONFITTO. « Chitons (Mollusca, Polyplacophora) from the Maldive islands ». Zootaxa 2673, no 1 (10 novembre 2010) : 1. http://dx.doi.org/10.11646/zootaxa.2673.1.1.
Texte intégralRésumé :
This paper is the first comprehensive and illustrated account of living Polyplacophora from the Maldive Islands. The only important previous contribution is that of E.A. Smith (1903), describing eight species. We determined 15 species sourced from 24 sampling sites, mainly at a depth of 20–40 meters, represented by 19 living specimens and 1112 valves. Only nine species (Parachiton hylkiae mauricejayi, Ischnochiton albinus, Ischnochiton sp., Rhyssoplax maldivensis, Tegulaplax hululensis, Lucilina sp., Acanthochitona penicillata, Craspedochiton cf. laqueatus, Cryptoplax burrowi) are represented by living specimens, the others by separate valves (Callochiton clausadeae, Lucilina perligera, L. carnosa, Acanthochitona sp., Craspedochiton sp., Cryptoplax sykesi), three of them (Lucilina perligera, Acanthochitona sp., Craspedochiton sp.) by only one or two valves. We did not find four of the species previously reported for the Maldives, i.e. Ischnochiton feliduensis, Callochiton platessa, Squamopleura miles and Schizochiton incisus. The specimen collected by J.S. Gardiner, and reported in Smith (1903) as Callochiton platessa Gould, has been studied, and it is not possible to attribute to any of the other Callochiton species from the Indian Ocean. It thus remains undetermined as Callochiton sp., and Callochiton platessa Gould must be deleted from the list of chiton species living in the Maldive Islands. The holotype of Ischnochiton feliduensis (the only specimen known) is illustrated to provide a complete and exhaustive survey of all the 19 chiton species now known from the Maldive Islands. Two species from other localities, Squamopleura miles and Schizochiton incisus, also are illustrated. The type material of Craspedochiton laqueatus and Cryptoplax burrowi has been examined. Eleven species are reported for the first time for the Maldives: Parachiton hylkiae mauricejayi, Ischnochiton albinus, Ischnochiton sp., Callochiton clausadeae, Lucilina perligera, L. carnosa, Lucilina sp., Acanthochitona penicillata, Acanthochitona sp., Craspedochiton sp. and Cryptoplax sykesi.

Texte intégralRésumé :
A census of scleractinian species was carried out in 2002 and 2003 in the atolls of South Male, Felidhu, Wataru and Ari, in the central Maldives. Thirty four stations were surveyed by scuba diving between the depths of 0 and 50m. One hundred and eighty zooxanthellate coral species belonging to 51 genera were recorded, of which 17 species belonging to 14 genera are new records for the Maldives. A complete list of zooxanthellate scleractinian species including our own results as well as documented records published by previous authors is given. This list includes 248 species belonging to 57 genera. The taxonomic status of a number of species of doubtful validity cited by previous authors is discussed. The need for additional sampling throughout the entire Maldive Archipelago and for a re-examination of Gardiner’s material is stressed.

Texte intégralRésumé :
A biodiversity survey carried out from 2016 to 2018 by the Department of Science and Technology in the Lakshadweep Atolls, India, recorded six species of shallow-water feather stars new to the archipelago (Comanthus wahlbergii, Comaster schlegelii, Himerometra robustipinna, Dichrometra palmata, Stephanometra indica, and Phanogenia typica). Himerometra sol A.H. Clark, 1912, previously known only from the Maldive Islands, is synonymized under Himerometra robustipinna (Carpenter, 1881). This study brings the total number of shallow-water crinoids recorded from Lakshadweep to ten species. Of the four species collected previously from the archipelago, only Comatella nigra was found in this survey. Of those not collected, Comatella stelligera and Oligometra serripinna are widespread in the Indo-western Pacific region, whereas Heterometra compta is known only from Lakshadweep, and its validity remains uncertain. The known shallow-water crinoid fauna of the archipelago is substantially less diverse than that of the adjacent and environmentally similar Maldive Islands, emphasizing the need for additional research in this island group, in particular, to determine whether the differences are actual or not, and whether they are based on natural conditions versus anthropogenic impacts.

Texte intégralRésumé :
The Chagos-Laccadiv Range is a linear-elongated structure adjacent to the passive margin of western India. The ridge consists of three segments: northern — Lakkadiv ridge, central — Maldives ridge and southern — bank (archipelago) Chagos. The ridges are separated by depressions and have different manifestations in morphology and anomalous gravitational field. Modeling of the density structure of the Chagos-Lakkadive Ridge tectonosphere showed that the Lakkadive and Maldive segments, most likely, represent submerged blocks of thinned continental crust, partially separated from the continental margin of India by a riftogenic basin. Along with the assumption that the Chagos Bank may contain fragments of the continental crust, the main factor in its formation is apparently the active magmatic activity of the Reunion hot spot, leading to an increase in the thickness of the crust due to underplating. Physical modeling showed that the formation of such a linear structure is possible in the presence of thermal (hot spot) and structural (faults and cracks) inhomogeneities in the model continental lithosphere, which within the continental margin led to a jump (jumping) of the spreading axis towards the young margin and partial separation from it narrow linearly elongated microblocks (ridges).

Texte intégralRésumé :
L’ecosistema delle scogliere coralline presenta una elevatissima diversità di specie, tuttavia è anche esposto a numerosi disturbi naturali ed antropici. Le minacce includono macro e micro-plastica, riscaldamento globale e predazione. La comprensione delle dinamiche ecologiche della scogliera corallina e le interazioni con attività umane è di primario interesse per evitare la perdita di biodiversità. Questa priorità è fondamentale per aree isolate e remote come la Repubblica delle Maldive, che risulta essere sensibile ai cambiamenti ambientali, anche se è un’area ancora poco investigata. Perciò, questo studio intende esplorare le maggiori minacce e interazioni che causano danni alla scogliera corallina maldiviana. In particolare la corallivoria, per cui, la struttura della popolazione, le preferenze alimentari e le variazioni di densità dei tre corallivori principali delle Maldive (Acanthaster planci, Culcita spp. and Drupella spp.) sono stati studiati. Questi corallivori hanno un ruolo nel deteriorare la copertura di corallo tramite predazione diretta e interazione con altri disturbi di origine antropica come l’aumento delle temperature delle acque. Ciò è specialmente valido per A. planci che ha sviluppato un’esplosione demografica nell’area di studio intensificando la pressione predatoria. Mentre Culcita spp. ha mostrato un ruolo potenzialmente specifico nel rallentare il recupero della scogliera corallina, poiché focalizza la predazione sulle reclute dei coralli. Al contratio, Drupella spp. ha mostrato un collasso della popolazione dopo un evento di mortalità dei coralli, riducendo la pressione predatoria senza apparentemente influenzare la fase di recupero. L’interazione tra corallivoria e minacce di origine antropica intensifica la mortalità dei coralli. Tuttavia non tutti i disturbi antropici sono conosciuti, spesso per mancanza di metodologie standard per quantificarli. Una minaccia aggiuntiva non ancora studiata in dettaglio è rappresentata dai detriti marini antropici (DMA). Perciò, un ulteriore obiettivo è stato quello di sviluppare un metodo efficace e rapido per monitorare e quantificare DMA sulle spiagge usando un drone e un sistema di intelligenza artificiale (IA) basato su un programma di apprendimento artificiale (PlasticFinder). L’alta risoluzione (0.5 cm/pix) dei dati ha permesso di rilevare più dell’ 87% degli oggetti presenti sulla spiaggia rappresentando uno strumento utile a monitorare rapidamente il tasso di accumulo di DMA anche in aree remote ed isolate o disabitate. Negl’ultimi decenni però le scogliere coralline hanno subito una elevata perdita di corallo vivo determinando lo sviluppo di tecniche per il restauro della scogliera corallina. Tuttavia, la valutazione dell’efficacia delle strategie di restauro sono limitate a pochi fattori, come sopravvivenza e crescita del corallo. Il coinvolgimento delle comunità di utenti delle scogliere coralline è stato dimostrato essere fondamentale. L’uso dell’analisi della soddisfazione degli utenti ha rivelato, in questo studio, il bisogno di intervenire con attività di restauro attivo invece che con l’uso di strutture artificiali. Inoltre, donne e locali si sono dimostrati i più interessati a dedicarsi a progetti di restauro, suggerendo che l’investimento nell’addestramento di queste categorie può risultare in una maggiore efficienza delle strategie di restauro. In conclusione, questo lavoro fornisce una visione dettagliata sull’impatto dei principali corallivori alle Maldive. Perciò può rappresentare un utile spunto per futuri studi sull’ecologia dei corallivori, e in più, per la comprensione di ulteriori impatti e strategie per salvaguardare la biodiversità delle scogliere coralline maldiviane.Coral reef is one of the most diverse ecosystem on Earth, yet one of the most exposed to natural and anthropogenic disturbances. Threats to coral reefs include macro and micro-plastic, global warming and natural coral predators. In this context, understanding the dynamics of coral reef and the interactions with anthropogenic activities is of primary interest to prevent the loss of the reef biodiversity. Such priority is fundamental for isolated and remote areas, such as the Republic of Maldives, which is highly sensitive to changes in environmental conditions, yet, barely investigated. Thus, this study is intended to explore natural and anthropogenic threats recently impacting the maldivian coral reef. Specifically, we investigated the population structure, feeding preferences, distribution and density variation of the three major corallivores occurring in the Maldives (Acanthaster planci, Culcita spp. and Drupella spp.). The results highlighted the role of corallivores in decreasing coral cover by direct predation and co-occurence with temperature-induced coral mortality. Especially for A. planci which showed a severe outbreak in the study area. While Culcita spp. showed a more specific possible role in delaying coral recovery, since resulted to focus predatory pressure on coral recruits. On the other hand, Drupella spp. showed a population collapse compared to previous studies in Maldives, reducing the predatory pressure during the recovery phase of the reef. Thus, the interaction between corallivores and anthropogenic disturbances intesify mortality of corals. Yet, not all disturbances are known, often for lacking of standard methodology for quantification. Among those, a further disturb not known in details is represented by marine anthropogenic debris (AMD). The purpose here was to develop an effective and time-saving method to monitoring and automatically quantifying AMD, using a commercial Unmanned Aerial Vehicle (UAV) and Artificial Intelligence (AI) with a deep-learning based software (PlasticFinder). The high resolution (0.5 cm/pix) of the data allowed to detect more than 87% of the object on the shores and the analysis from PlasticFinder reached a Positive Predictive Value of 94%, which overcame the limits highlighted in the previous AI algorithm used in the literature. The use of drone resulted in a time saving tool to survey AMD accumulation even in remote areas such as uninhabited islands. The degradation of the maldivian coral reef caused by anthropogenic and natural disturbances is a trigger for active strategies to enhance recovery through coral restoration. However, assessment tools of restoration effectiveness and development are still restricted to few ecological factors, such as coral survival and growth. Very few studies included other factors such as socio-economic assessment. The involvement of the community of users of the coral reefs are as important as factors related directly to corals, since users’ satisfaction may drive allocation of private funding useful to improve restoration success. Results presented here, revealed weak points and ways to improve coral restoration programs management in two resorts in the Maldives. The use of satisfaction analysis revealed the need for intervention dedicated to active restoration rather than using artificial reef. Further, women and Maldivians resulted to be the most willing to dedicate themselves to coral restoration project. Thus, suggesting that training session by the resort may be organized for such categories to build team of volunteers for improving local restoration programs. In conclusion, this work provide a detailed overview of the impacts of the main corallivores on the maldivian coral reef. Therefore, it may represent a baseline for future research on the ecology of coral predators and, additionally, for the understanding of further anthropogenic disturbances and for improving strategies to prevent the loss of maldivian coral reef biodiversity.

Texte intégralRésumé :
Lo studio delle malattie che colpiscono i coralli rappresenta un campo di ricerca nuovo e poche sono le ricerche concentrate nell’Oceano Indo-Pacifico, in particolare nella Repubblica delle Maldive. Lo scopo di questa ricerca è stato approfondire le conoscenze riguardo distribuzione, prevalenza e host range della Skeleton Eroding Band (SEB) nell’atollo di Faafu. Durante il lavoro, svolto in campo tra il novembre e il dicembre 2013, sono state indagate le isole di: Magoodhoo, Filitheyo e Adangau al fine di rilevare differenze nei livelli di prevalenza della SEB in relazione ai diversi gradi di utilizzo da parte dell’uomo delle 3 isole. Il piano di campionamento ha previsto la scelta casuale, in ciascuna delle isole, di 4 siti in cui sono stati realizzati 3 belt transect e 3 point intercept transect a 2 profondità predefinite. La SEB è stata ritrovata con una prevalenza media totale di 0,27%. Dai risultati dell’analisi statistica le differenze fra le isole non sono apparse significative, facendo ipotizzare che i livelli di prevalenza differiscano a causa di oscillazioni casuali di carattere naturale e che quindi non siano dovute a dinamiche legate al diverso sfruttamento da parte dell’uomo. I generi Acropora e Pocillopora sono risultati quelli maggiormente colpiti con valori di prevalenza totale di 0,46% e 1,33%. Infine è stata rilevata una correlazione positiva tra il numero di colonie di madrepore affette dalla SEB e il numero di colonie in cui la malattia è associata alla presenza di lesioni provocate da danni meccanici. I dati di prevalenza ottenuti e le previsioni di cambiamenti climatici in grado di aumentare distribuzione, host range, abbondanza della patologia, pongono l’accento sulla necessità di chiarire il ruolo delle malattie dei coralli nel deterioramento, resilienza e recupero dei coral reefs, al fine di attuare politiche di gestione adatte alla protezione di questi fragili ecosistemi.

Texte intégralRésumé :
Nonostante lo sforzo sempre crescente mirato allo studio delle malattie che colpiscono le sclerattinie, ancora poco si sa circa distribuzione, prevalenza, host range e fattori che concorrono alla comparsa di queste patologie, soprattutto nell’area indopacifica. Questo studio si propone quindi lo scopo di documentare la presenza della Brown Band Disease all’interno delle scogliere madreporiche dell’Arcipelago delle Maldive. Nell’arco di tempo tra Novembre e Dicembre 2013 è stata effettuata una valutazione di tipo quantitativo di tale patologia su tre isole appartenenti l’Atollo di Faafu, rispettivamente Magoodhoo, Filitheyo e Adangau. Queste tre isole sono caratterizzate da un diverso sfruttamento da parte dell’uomo: la prima isola è abitata da locali, la seconda caratterizzata dalla presenza di un resort e l’ultima, un’isola deserta. Al fine di valutare prevalenza, distribuzione e host range della BrBD sono stati effettuati belt transect (25x2 m), point intercept transect e analisi chimico fisiche delle acque.
La Brown Band Disease è risultata essere diffusa tra le isole con prevalenze inferiori al 0,50%. Queste non hanno
mostrato differenze significative tra le isole, facendo quindi ipotizzare che i diversi valori osservati potrebbero essere imputati a variazioni casuali e naturali. In tutta l’area investigata, le stazioni più profonde hanno mostrato valori di prevalenza maggiori. La patologia è stata registrata infestare soprattutto il genere Acropora (con prevalenza media totale inferiore all’1%) e in un solo caso il genere Isopora. È stato dimostrato come sia presente una correlazione negativa tra densità totale delle sclerattinie e la prevalenza della Brown Band sul genere Acropora. É stato inoltre notato come vi fosse una correlazione positiva tra la prevalenza della BrBD e la presenza del gasteropode Drupella sulle colonie già malate. Poiché il principale ospite della patologia è anche il più abbondante nelle scogliere madreporiche maldiviane, si rendono necessari ulteriori accertamenti e monitoraggi futuri della BrBD.

Texte intégralRésumé :
La frequenza degli episodi di coral bleaching è aumentata interrottamente nelle ultime decadi a causa dell’incremento di temperatura registrato nei diversi oceani del pianeta. Nell’Arcipelago Maldiviano, tali eventi sono stati osservati principalmente nei mesi seguenti il picco di episodi El-Niño molto intensi. Il bleaching tuttavia non è stato uniforme e alcuni reef sono stati colpiti solo marginalmente. Ho utilizzato i dati da satellite e un modello oceanico regionale (CROCO) per investigare la variabilità, sia spaziale sia temporale, della temperatura superficiale dell’oceano (SST) e quantificare l’entità relativa di episodi legati ad ENSO, confrontandoli con l’effetto dell’incremento della temperatura negli ultimi decenni. In linea con altri studi effettuati, è stato confermato che il trend di temperatura aumenta significativamente la frequenza di episodi di stress termico per i coralli. È stato anche scoperto che, durante la stagione più calda, l’interazione tra le correnti e la ripida batimetria è responsabile di una diminuzione locale della temperatura elimina virgole avanati e dietro nell’Arcipelago di circa 0.2°C rispetto all'oceano circostante. Questo raffreddamento riduce notevolmente la frequenza di condizioni di mortalità per i coralli. La riduzione della SST attorno alle Maldive è probabilmente collegata all’Island Mass Effect: l’incremento di produttività intorno a isole di dimensione ridotte scoperto negli anni sessanta e documentato in tutto il mondo. Nonostante il suo effetto sulla produttività marina, l’esatto quadro dei processi che stanno dietro al raffreddamento locale e l’input di nutrienti che accresce la produttività è ancora incerto. Dall'analisi delle variazioni di SST e della produttività primaria netta (NPP) intorno a numerose isole ed arcipelaghi di piccole dimensioni sono stati identificati due tipi di pattern. Intorno ad isole con un'altitudine considerevole e dimensioni maggiori, infatti, sono visibili anomalie calde/fredde, probabilmente corrispondenti ad aree di upwelling e downwelling. Aree più calde non sono invece visibili intorno ad isole di dimensioni minori. Sono diversi i processi, sia oceanici sia atmosferici, che potrebbero essere coinvolti e contribuire a generare il pattern di temperatura. Ho studiato nel dettaglio il caso delle Maldive, utilizzando CROCO - aumentando la risoluzione - ed un modello di particles tracking, Ariane, ed è emerso che il meccanismo predominante varia durante l’anno e dipende dalla direzione e magnitudo delle correnti. Vicino alle Maldive il rallentamento delle correnti a causa dell’attrito dovuto ad una batimetria poco profonda produce un forte shear verticale, che favorisce il mescolamento verticale e produce un raffreddamento quasi simmetrico intorno alle isole. Un altro meccanismo domina il pattern di raffreddamento quando le correnti sono particolarmente intense, come durante i monsoni: forti correnti zonali attraversano l’Arcipelago e generano wake intense con un elevato shear orizzontale; un intenso upwelling si origina nelle scie, creando un segnale di temperature asimmetrico (raffreddamento maggiore nella scia delle isole) e offuscando gli effetti del rafforzato mescolamento verticale.The frequency of coral bleaching events has been increasing in recent decades due to the temperature rise registered in most regions near the ocean. Their occurrence in the Maldivian Archipelago has been observed in the months following the peak of strong El Niño events. Bleaching has not been uniform, and some reefs have been only marginally impacted. I have used satellite observations and a regional ocean model (CROCO) to explore the spatial and temporal variability of sea surface temperatures (SSTs), and quantify the relative magnitude of ENSO-related episodes with respect to the recent warming. In line with other studies, it is confirmed that the long-term trend in SST significantly increases the frequency of stress conditions for the Maldivian corals. It is also found that the interaction between currents and the steep bathymetry is responsible for a local cooling of about 0.2°C in the Archipelago during the warmest season, with respect to the surrounding waters. This cooling largely reduces the frequency of mortality conditions. The reduced SST surrounding the Maldives is probably linked to the Island Mass Effect: the enhanced productivity around small islands discovered in the sixties and documented worldwide. Despite its effects on marine productivity, the exact description of the physical processes behind the local cooling and nutrient input that enhances productivity is still unclear. From the analysis of SST variations and net primary productivity (NPP) around small islands and archipelagos, two kinds of signals can be identified, depending on the altitude and dimension of the islands. Around islands with considerable elevation and greatest diameters, cold/warm anomalies, most likely corresponding to upwelling/downwelling zones, emerge. Warmer areas don’t appear around smaller islands that usually display only a local cooling. Several oceanic and atmospheric processes might be involved. The case of the Maldives has been analyzed in detail using CROCO with increased resolution and a particle tracking model: Ariane. More than one process might coexist in generating the described patterns, the prevailing one varying along the year and depending on the strength and direction of the incoming flow. Near the Maldives, the frictional break of the currents in the presence of shallow bathymetry produces a strong vertical shear in the flow that favors vertical mixing and produces a nearly symmetric cooling around the islands. A different mechanism dominates the cooling pattern when the currents are particularly intense, such as during the monsoons: intense zonal currents cross the Archipelago and give rise to intense wakes with large horizontal shear; strong upwelling originates in the lees, creating an asymmetric temperature signal (larger cooling in the lee of the islands) and obfuscating the effects of the enhanced vertical mixing.

Texte intégralRésumé :
Approved for public release; distribution is unlimitedThis thesis aims to explore the rise of Islamism and Islamic radicalism in the Republic of Maldives. It analyzes the causes and grievances which have fueled the rise of political Islam, as well as its radical elements, and the main groups operating in both the political and social space (as well as on the fringes), including an analysis of their main ideological drivers and their social and political outlook. The closed and conspiratorial nature of the Maldivian political environment, as well as the use of repression to quell political dissent and the manipulation of Islamic religious ideals to cement political position was one factor that led to the rise of Islamism and Islamic radicalism. Another was the rapid modernization that introduced alien concepts and values into Maldivian society. These militated against the traditional norms and cultures and wrought havoc on the social structures, causing intense alienation and social dislocation. All these changes were taking place in a context where Maldives was being infiltrated by radical elements, both local and foreign. They made ample use of the social conditions to craft and narrative that was conducive to their recruitment and radicalization efforts.

Rechercher la genèse et les usages sociaux du mot bandit c est le but de mon travail. Voilà pourquoi j adopte trois concepts opérationnels: archéologie, de Foucault; pli, de Deleuze et rhizome, de Deleuze et Guatari. Cependant, analyser un mot remet à l etude de tout ce qui l engage, mis dans les mots qu elle entreprend et aux termes auxquels ils s associent. Aisi, dans l ensemble des mot entrepris par bandit ou y attélés, un terme synonyme se met en évidence, criminel . Cependant, les synonymes constituent des babillages, puisqu aucunt mot ne dit un autre. Ainsi, je dévoile le parcours historique de ces deux termes, criminel et bandit , en analysant, d abord, les usages sociaux du mot criminel et après, du mot bandit. Criminel, au XIXe. siècle, constitue une catégorie générale désignative du délinquant, y compris le criminel politique ou bandit. Mais, peu à peu le bandit qui constituait autrefois une catégorie particulière de criminel, criminel politique, devient catégorie générale à partir de la fin du XIXe. siècle et début du XXe., en désignant, dans la presse, toute sorte de délinquant. En tant que terme central dans la première partie intitulée Sociologie de la Méchancité et Méchancité de la Sociologie , le mot criminel essaie d analyser la méchancité qui gagne une visibilité dans le corps du criminel, selon les discours de la physiognomonie, de la phrénologie, de la craniométrie et de la criminologie. Telles visibilités constituent un discours d exclusion, basé sur la peur sociale, le déni de cette émotion et sa transformation en haine. Ainsi, une Sociologie de la Méchancité doit analyser les facteurs sociaux existants dans la transformation de peur en haine, en discutant une et d autres émotions, en tant que des faits historiques qui rendent possible l invention de la survellance et du contrôle sociaux. Méchancité de la Sociologie, par contre, n est que l usage stratégique de la sociologie de la part du Pouvoir qui s en sert comme un moyen de rationalisation pour la surveillance, le contrôle, l exclusion, au nom de la sécurité sociale devant la possibilité de danger de certains groupes sociaux, pris comme suspects et/ou criminels. À la deuxième partie, où spécifiquement l on recherche l Archéologie du Bandit, à la façon de reconstituer le parcours historique de bandit , j élabore une analyse biographique sur Antônio Vicente Mendes Maciel, le Conselheiro , le bandit typique des premières années de la République Brésilienne, tandis que j analyse la guerre de Canudos comme exemple d exclusion sociale, par les rites sacrificatoires engagés dans les chocs entre le Même et l Autre. Le cas Conselheiro peut servir soit à démontrer l usage social du mot bandit, importe du settecento français, soit à l usage national des savoirs produits en Europe à la fin du XIXe. siècle quand le concept de criminel est créé, recapitules parmi nous par Raimundo Nina Rodrigues et Euclydes da Cunha. Dans les Inconclusões du travail, à partir des concepts sociaux de criminel et bandit, je renvoie à la discussions sur les notions de contrôle, surveillance et exclusion, mises entre la croyance de l égalité et le manque de respect à la différence et médiatrices de certaines relations entre lê Même et l Autre.
Investigar a gênese e os usos sociais da palavra bandido, este o objetivo de meu trabalho. Para tanto, lanço mão de três conceitos operacionais: arqueologia, de Foucault; dobra, de Deleuze; e rizoma, de Deleuze e Guatari. Analisar um vocábulo, porém, remete ao estudo dos seus entornos, colocados nas palavras que ele agencia e nos termos que àquele se associam. Dessa forma, na rede dos vocábulos agenciados pela palavra bandido ou a ela associados, um termo sinônimo ganha destaque, criminoso. Entretanto, sinônimos são falácias, pois nenhuma palavra diz outra. Pensado assim, ponho a descoberto o percurso histórico destes dois termos, criminoso e bandido, analisando, na primeira parte, os usos sociais do vocábulo criminoso e, na segunda, os usos sociais da palavra bandido, tendo-se que criminoso, no século XIX, é categoria geral designativa do delinqüente, entre os quais se inclui o criminoso político ou bandido. Gradativamente, porém, o bandido, que era categoria particular de criminoso, criminoso político, passa a categoria geral, a partir do final do século XIX e início do século XX, designando, no jornalismo, toda e qualquer modalidade de delinqüente. Termo nuclear na primeira parte, intitulada Sociologia da Maldade & Maldade da Sociologia , o vocábulo criminoso enseja analisar a maldade que, de acordo com os discursos da fisiognomonia, da frenologia, da craniometria e da criminologia, ganha visibilidade no corpo do criminoso. Tais dizibilidades formatam um discurso de exclusão, calcado no medo social, na denegação dessa emoção e na sua transformação em ódio. Assim sendo, uma Sociologia da Maldade deve analisar os fatores sociais alocados na transformação daquele medo nesse ódio, discutindo uma e outra emoções, enquanto fatos históricos possibilitantes da invenção da vigilância e do controle sociais. Maldade da sociologia, por outro lado, nada mais é que a utilização estratégica da sociologia por parte do Poder, que dela se serve como forma de racionalização para a vigilância, o controle, a exclusão, em nome da segurança social, diante da suposta periculosidade de certos grupos sociais, assinalados como suspeitos e/ou criminosos. Na segunda parte, onde especificamente é investigada a Arqueologia do Bandido, à guisa de reconstituir o percurso histórico do termo bandido, elaboro uma análise biográfica sobre Antônio Vicente Mendes Maciel, o Conselheiro, o bandido típico dos primeiros anos da República Brasileira, enquanto analiso a guerra de Canudos como exemplo de exclusão social, pela via dos ritos sacrificiais envolvidos nos embates entre o Mesmo e o Outro. O caso Conselheiro tanto serve para demonstrar o uso social do termo bandido, importado do settecento francês, quanto o uso nacional dos saberes produzidos na Europa ao final do século XIX, quando é inventado o conceito de criminoso, recapitulados entre nós por Raimundo Nina Rodrigues e Euclydes da Cunha. Nas Inconclusões que encerram o trabalho, partindo dos conceitos sociais de criminoso e de bandido, remeto à discussão sobre as noções de controle, vigilância e exclusão, colocadas entre a crença da igualdade e o desrespeito à diferença e mediadoras de certas relações entre o Mesmo e o Outro.

Les Maldiviens exploitent durablement le thon dans l'océan Indien depuis plus d'un millénaire, avec 20% des captures totales de thon de l'océan Indien actuellement débarquées aux Maldives. Après quatre décennies d'utilisation d'une moyenne de 55 dispositifs de concentration de poissons ancrés (DCPA-) répartis sur l'ensemble de l'archipel, cette thèse vise à améliorer nos connaissances sur l'écologie de la pêche au thon au sein du réseau de DCP des Maldives afin de mieux comprendre les moteurs de la durabilité de la pêche pour les années à venir. L'écologie du thon autour de ces DCP a été étudiée en recueillant les connaissances écologiques locales de 54 pêcheurs à la canne et en marquant acoustiquement 65 listaos et 57 albacores dans un réseau de 21 DCP instrumentés. La plupart des pêcheurs considèrent que des courants faibles, une température de la mer adaptée, des proies et des attractifs favorisent les agrégations tandis que des courants forts, des températures de la mer élevées et des conditions orageuses font que les thons quittent les DCP. Ils considèrent également que les thons ont tendance à rester associés aux DCP de 3 à 6 jours, ce qui est comparable aux résultats du marquage acoustique (de 2 à 5,5 jours en moyenne). Le marquage acoustique a montré que les thons n'ont pas de préférence spécifique dans la direction du mouvement, et que très peu de poissons se déplacent d'un DCP à l'autre. Par conséquent, les 55 DCP des Maldives ne fonctionnent pas comme un réseau mais semblent être relativement indépendants. Le réseau de DCP des Maldives peut être considéré comme une étude de cas pour examiner les avantages et les inconvénients des réseaux de DCP peu denses comme supports pour les pêcheries, tout en minimisant les impacts négatifs potentiels.

After four decades using on average 55 anchored fish aggregating devices (AFADs) spread over the entire archipelago, this thesis aims to improve our knowledge on the fishery ecology of tuna within the Maldivian AFAD array in order to better understand the drivers of the sustainability of the fishery for the coming years. The ecology of tuna around these AFADs was studied by collecting local ecological knowledge from 54 pole and line fishers and by acoustically tagging 65 skipjack and 57 yellowfin tuna within an instrumented 21-AFAD array. Most fishers consider that slight currents, suitable sea temperature, prey and attractants enhance the aggregations while strong currents, high sea temperatures and stormy conditions make tuna leave AFADs. They also consider that tuna tend to stay associated with AFADs 3 to 6 days, which is comparable to results from acoustic tagging (from 2 to 5.5 days on average). Acoustic tagging showed that tuna do not have a specific preference in the direction of movement, and very few fish moved from one FAD to another. Therefore, the 55 AFADs in the Maldives do not act like a network but appear to be relatively independent. The Maldives FAD network can be considered as a case study to examine the pros and cons of sparse FAD networks as supports for fisheries, while minimizing potential negative impacts. More research on the ecological, social and economic aspects of the pole and line fishery must be conducted to support the Maldives in their science-based management.Keywords: Anchored Fish Aggregating Device, Tropical tunas, Pole and Line, Maldives, Local Ecological Knowledge, Residence Time

Texte intégralRésumé :
Abstract Substance misuse is a global phenomenon. However, little is known about substance misuse issues in Islamic nations or about the provision of preventative and rehabilitative services in such nations. This thesis explores the legal context of such services in the Maldives and pays particular attention to tensions between the formal policies of the National Narcotics Control Bureau and clinical practice. Findings are drawn from a review of government and service policy documents, five semi-structured individual interviews with clinical practitioners and senior administrative staff from rehabilitative services, and a three day focus group workshop with clinical staff. Findings show the lack of awareness of the legal and policy contexts for service provision and the ways in which existing policy frameworks often detract from the forging of therapeutic alliances. The primary concern raised by the analysis is the lack of involvement of clinical staff in policy formation and revision. This contributes to series of tensions and contradictions between official aims for services and the actual provision of these services. Further a range of ethical issues arose as a result of inadequate professional monitoring, training, and peer review. Recommendations are made regarding how these issues should be addressed in order to enhance the Maldivian response to increasing substance misuse.

Texte intégralRésumé :
In the Asian and other monsoon regions of the world most of the severe weather observed is local or mesoscale in nature. Forecasting convective storms or mesoscale systems in the monsoon regions, especially in the tropics, has always been a challenging task to operational meteorologists. Maldives Islands, being situated in the tropical Indian Ocean, are affected by monsoon depressions and tropical cyclones. Thunderstorms and the passage of squall lines are well known sources of heavy rainfall. However, due to the lack of professional people and necessary equipment the weather systems around these islands are seldom studied. Therefore the aim of this thesis is to investigate whether the small islands can create sufficient perturbations in the mesoscale environment to result in the development of convective systems. In this regard, two numerical models, Weather Research and Forecasting model (WRF version 2.2.1) and Regional Atmospheric Modelling System (RAMS version 6.0) were used in this study. Two experiments were performed using the WRF model. In the first experiment, a case study was investigated where the selected day experienced heavy rainfall and thunderstorms. In the second experiment, the same case study was used but with the topographical and surface properties removed in order to investigate the influence of the island in modifying the mesoscale environment. All the experiments were initialized using the re-analysis data from NECP. WRF was able to predict the large scale synoptic features with reasonable accuracy when compared to the observations. Development of the boundary layer and the downstream advection of the temperature anomaly generated by the island were well represented. However, the magnitude of the effects was shown to be weak, probably due to the influence of large scale synoptic features. Even though the model was able to predict the large scale features and some of the mesoscale features, it did not predict any storm development and underestimated the precipitation. Therefore, it was decided to idealize the storm development using the RAMS model. RAMS model was used in a two-dimensional framework. The model was initialized horizontally homogenous using a single sounding and six simulations were performed. The simulation results clearly depicted that the small island can generate its own circulation and influence the mesoscale environment. The daytime heating of the island and the downstream advection of the temperature anomaly in a moist unstable atmosphere could trigger a thunderstorm later in the day. The storm becomes mature approximately 40-80 km offshore. This also suggests that triggering of a storm on one side of an atoll could influence the islands on the downstream side. Sensitivity of storm development to the thermodynamics showed that even with an unstable atmosphere, enough moisture in the lower and mid-troposphere is needed to trigger the storm. Sensitivity to the change of SST showed that convective development was suppressed with a drop of 1 oC. However, this needs further investigation. Assessment of sensitivity to the size of the island showed that the time of triggering of the storm was later and the scale of influence was smaller with a smaller island.

Texte intégralRésumé :
Many powerful laser based methods are unavailable for the analysis of molecules in solution. Techniques for the analysis of liquids are particularly important for the study of biomolecules, whose natural environment is a water solution. Mass spectrometry is a powerful analytical technique, but liquids and mass spectrometers are fundamentally incompatible. We have developed a technique for laser ionization of biomolecules in solution by applying matrix-assisted laser desorption ionization (MALDI) to liquid aerosols. In the typical MALDI experiment, the analyte biomolecule is deposited from solution onto a metal surface with a 100 to 50,000 molar excess of a suitable matrix, usually a UV absorbing organic acid.1 The solvents are allowed to evaporate and the sample is inserted into the source region of a mass spectrometer. Light from a pulsed laser is absorbed by the matrix causing both ablation of the surface and ionization of the intact biomolecule. In the aerosol MALDI experiment, 2,3 the analyte biomolecule is dissolved in a methanol solution with an ultraviolet absorbing matrix. The aerosol is sprayed into vacuum, desolvated, and ionized by pulsed UV laser radiation. The ions are mass separated in a time-of-flight (TOF) mass spectrometer. Aerosol MALDI mass spectra have been obtained for a variety of peptides and proteins with molecular weights as large as 80,000. We have used aerosol MALDI as a liquid chromatography detection method4 (LC/MS) and as a probe of aerosol and cluster chemistry.5 This paper gives a general description of aerosol MALDI and discusses some recent results for peptide and protein ionization.

Texte intégralRésumé :
The recent development of Matrix Assisted Laser Desorption / Ionization (MALDI) has sparked a revolution in the field of high molecular weight mass spectrometry.1 Time-of-flight (TOF) mass spectra of proteins weighing up to 300,000 Da are now routinely produced and this achievement has fostered a variety of bioanalytical applications which were previously unapproachable using conventional mass spectrometric techniques. These successful applications have burgeoned in spite of a poor understanding of the mechanism of analyte desorption and ionization under MALDI conditions. An improved understanding of the MALDI mechanism should aid in overcoming a number of limitations of the current state-of-the-art and forms the motivation for the work described.

Além de encontrarmos preconceitos, temos uma questão da história por trás e como tudo começou, como as dificuldades durante a vinda dos primeiros imigrantes no Brasil no ano de 1908, no século XX. Mostrando como os japoneses tinham certas dificuldades financeiras, para voltar ao seu país natal e a questão de aprender uma língua nova. Com o período da Primeira e Segunda Guerra Mundial, isso se tornou mais complicado, onde os imigrantes que vieram estavam com intuito de poder vir assim que acabassem às duas guerras, porém nos dias 6 a 9 de agosto em 1945 o Japão foi bombardeado pelos Estados Unidos, onde tivemos cerca de 70 mil mortos.

<p>The piers no.19~21 of the main bridge of China-Maldives Friendship Bridge are V-shaped piers, which are constructed by the method of "cast-in-place slant legs with cable-stayed connection and hanging section + cast-in-place block no.0 with inner supports". Based on the analysis of the whole construction stage of the bridge by the finite element method, the factors of concrete cracking during the construction of V-shaped piers are grasped. In view of the risk of structural cracks, the scheme of setting prestressed steel beam in the slant legs and accurately controlling the removal time of the cable hanging bracket is adopted to effectively prevent the concrete cracking during the construction of V-shaped piers.</p>

Texte intégralRésumé :
This study aims to build an efficient small-scale macroeconomic forecasting tool for Maldives. Due to significant limitations in data availability, empirical economic modeling for the country can be problematic. To address data constraints and circumvent the “curse of dimensionality,” Bayesian vector autoregression estimations are utilized comprising of component-disaggregated domestic sectoral production, price, and tourism variables. Results demonstrate how this methodology is appropriate for economic modeling in Maldives. With the appropriate level of shrinkage, Bayesian vector autoregressions can exploit the information content of the macroeconomic and tourism variables. Augmenting for qualitative assessments, the directional inclination of the forecasts is improved.

Texte intégralRésumé :
This working paper shows how Maldives can boost recycling to strengthen its solid waste management strategy, protect its blue ocean economy, and create green business opportunities to support its long-term sustainable growth. Estimating under 2 percent of plastic waste is recycled in the island nation, it outlines how factors including high costs, inefficient collection efforts, and a lack of reprocessing facilities are hobbling recycling efforts. It recommends Maldives set up public-private partnerships with waste exporters and recyclers, incentivize domestic demand, and build a modern waste collection system to protect its environment and start the transition to a circular economy.
