Abstract This study is an attempt to determine potential tsunamigenic morphostructural nodes in mainland Greece using pattern recognition algorithms. The earthquakes that have produced local tsunamis in the region were confined to morphostructural nodes whose locations were found by morphostructural zoning. The recognition problem consisted in separating all nodes in the region into the tsunamigenic class and the non-tsunamigenic class based mainly on the geomorphologic parameters of the nodes. The data on tsunamigenic earthquakes in Greece for training the Cora-3 algorithm were taken from the GHTD global historical catalog of tsunamigenic events (http://www.ngdc.noaa.gov/hazard/tsu_db.shtml). The recognition procedure resulted in determining 27 tsunamigenic nodes, with most of these being situated in the southern tip of the Peloponnese Peninsula, as well as in the gulfs of Corinth and Patras. Three tsunamigenic nodes were identified in the area of the Malian Gulf on the Aegean coast of Greece. According to the relevant literature, most local tsunamis in Greece were initiated by submarine slides and slumps due to earthquakes. According to the characteristic geomorphologic features derived in this study, the tsunamigenic nodes are situated in settings of contrasting relief characterized by steep slopes. This favors submarine landslides when subjected to earthquake excitation. The results reported in this paper form a basis for developing a methodology to be used in long-term tsunami hazard assessment, supplying information on local potential tsunamigenic sources required for tsunami regionalization of coastal areas in Greece.

Over Time

In conditions of severe water-pollution and dormant community acceptance of accumulating environmental damage, the regulator's role goes beyond pollution prevention and more towards remediation and solutions based on the community's long-term expectations of economic benefits from clean water. This paper suggests a method to enable these benefits to become perceptible progressively, through participatory clean-up operations, supported by staggered pollution charges. It analyses the relevant literature on pollution prevention and applies a cost-based “willingness to pay” model, using primary basin-level data of total marginal costs. It develops a replicable demand-side approach imposing charge-standard targets over time in urban-industrial basins of developing countries.

Of Greece

The front cover of John Bintliff's Complete Archaeology of Greece is interesting. There is the Parthenon: as most of its sculptures have gone, the aspect is post-Elgin. But it stands amid an assortment of post-classical buildings: one can see a small mosque within the cella, a large barrack-like building between the temple and the Erechtheum, and in the foreground an assortment of stone-built houses – so this probably pre-dates Greek independence and certainly pre-dates the nineteenth-century ‘cleansing’ of all Byzantine, Frankish, and Ottoman remains from the Athenian Akropolis (in fact the view, from Dodwell, is dated 1820). For the author, it is a poignant image. He is, overtly (or ‘passionately’ in today's parlance), a philhellene, but his Greece is not chauvinistically selective. He mourns the current neglect of an eighteenth-century Islamic school by the Tower of the Winds; and he gives two of his colour plates over to illustrations of Byzantine and Byzantine-Frankish ceramics. Anyone familiar with Bintliff's Boeotia project will recognize here an ideological commitment to the ‘Annales school’ of history, and a certain (rather wistful) respect for a subsistence economy that unites the inhabitants of Greece across many centuries. ‘Beyond the Akropolis’ was the war-cry of the landscape archaeologists whose investigations of long-term patterns of settlement and land use reclaimed ‘the people without history’ – and who sought to reform our fetish for the obvious glories of the classical past. This book is not so militant: there is due consideration of the meaning of the Parthenon Frieze, of the contents of the shaft graves at Mycenae, and suchlike. Its tone verges on the conversational (an attractive feature of the layout is the recurrent sub-heading ‘A Personal View’); nonetheless, it carries the authority and clarity of a textbook – a considerable achievement.

<p>Since May 2018, Mayotte island has experienced an important seismic activity linked to the on-going sismo-volcanic crisis. The epicenters of the seismic swarms are located between 5 and 15 km east of Petite Terre for the main swarm, and 25 km east of Petite Terre for the secondary swarm. Although variations in the number of earthquakes and their distribution have been observed since the start of the eruption in early July 2018 [Lemoine A.(2020), Cesca et al.(2020)], a continuous seismicity persists and could generate several earthquakes of magnitudes close to M4 widely felt by the population. This recurrent seismicity could weaken the steep submarine slopes of Mayotte, as highlighted by the high resolution bathymetry data collected during the MAYOBS cruise in May 2019 (Feuillet et al.,submitted) and trigger submarine landslides with associated tsunamis.</p><p>To address the hazards associated with such events, we analyzed morphological data to define 8 scenarios of potential submarine slides with volumes ranging from 11,25.10<sup>6</sup> to 800.10<sup>6</sup> m<sup>3</sup> and we simulate the landslide dynamics and generated waves. We use two complementary numerical models: (i) the code HYSEA to simulate the dynamic of the submarine granular flows and the water wave generation, and (ii) the Boussinesq FUNWAVE- TVD model simulate the waves propagation and the inundation on Mayotte. The effect of the time at which the models are coupled is investigated.</p><p>The most impacting submarine slide scenarios are located close to Petite Terre at a shallow depth. They can locally generate a sea surface elevation more than a meter in local areas especially at Petite Terre. The various simulations show that parts of the island are particularly sensitive to the risk of tsunamis. Indeed, some scenarios that does not cause significant coastal flooding still seems to cause significant hazards in these exposed areas. The barrier reef around Mayotte has a prominent role in controlling the wave propagation towards the island and therefore reducing the impact on land. It should be noted that the arrival of tsunamis on the coastline is not necessarily preceded by a retreat from the sea and the waves can reach the coasts of Mayotte very quicky (few minutes).</p><p> </p><p>Cesca, S., Letort, J., Razafindrakoto, H.N.T. et al. Drainage of a deep magma reservoir near Mayotte inferred from seismicity and deformation. Nat.

Key Terms

Job role localization is a strategic local content solution used by countries bearing natural resource stocks to maximize the long-term benefits of exploring and producing them. Currently, there is significant variation in how countries and organizations plan and implement local content and job role localization strategies; hence, this paper aims to gather, classify, and discuss relevant literature with a view to identify best practices for future application. After a multi-dimensional discussion of key terms relevant to the topic, the drivers and theoretical underpinnings of local content are examined, followed by an assessment of job role localization literature qualifying enablers and barriers to localization. A critical discussion on the means of evaluating local content policies summarizes the findings of this critical review.

Severe Personality Disorder

BackgroundSevere personality disorder (SPD) is an imprecise but useful term referring to some notoriously difficult to treat psychiatric patients. Their long-term psychiatric treatment is often unsuccessful, in spite of hospitalisation. The specialist expertise of in-patient psychotherapy units (IPUs) can successfully meet some of SPD patients' needs.MethodRelevant literature on the subject is summarised and integrated with the authors' specialist clinical experience.ResultsMany clinical problems with SPD patients are interpersonal and prevent any effective therapeutic alliance, which is necessary for successful treatment. With in-patients, inconsistencies in treatment delivery and issues surrounding compulsory treatment reinforce patients' mistrust of professionals, compromising accurate diagnosis and an assessment of the need for specialist IPU referral.ConclusionsGeneral psychiatric teams are well-placed to plan long-term treatment for SPD patients which may include IPU treatment. Timely referral of selected SPD patients to an IPU maximises a successful outcome, especially if there is appropriate post-discharge collaboration with general psychiatric teams to consolidate gains made.

The paper deals with the role and significance of election campaigns through a consideration of the relevant literature in political science, communication and anthropology. The current interpretation of elections as ritual and drama is altered by focusing on V. Turner's concept of liminality. As liminal periods, it is claimed, election campaigns are an active arena for social construction of political worlds. They take an active part in moulding political cognition and thus produce long-term effects. Perceiving elections in this conceptual frame focuses the empirical concern on the different actors participating in moulding old or new social meanings, the way challenging alternatives are presented, negotiated, included or excluded, the way events as well as symbols become meaningful. It reveals the contested as well as the taken-for-granted, unquestioned and thus reinforced political symbolic world.

Objective To evaluate the long-term results of using the BacJac interspinous device (Pioneer Surgical Technology Inc.) in a series of patients with degenerative lumbar spine disease. Methods Forty-one patients undergoing lumbar surgery with implantation of a BacJac device from 2009 to 2012 were enrolled in the present study. Patients were evaluated using the Oswestry Disability Scale (ODI). Results Although all patients showed a significant improvement of the ODI score immediately after surgery, only 41% of patients showed a satisfactory outcome. We observed worse results in the patients operated on at the L3–L4 level and in whom the device was implanted in a segment different from the one where surgical decompression had been performed. Weight gain in the months after surgery was also a poor outcome-influencing factor. Conclusions This study confirms what is already suggested in the relevant literature regarding the long-term inefficacy of the so-called dynamic stabilization devices.
