No full textMerle Greene Robertson (1913-2011) figura entre los académicos que en el siglo XX dieron forma a los modernos estudios sobre los mayas. Ella realizó las primeras calcas en muchos de sus sitios, y al cabo de una vida las cinco mil calcas de su legado están en el Departamento de Libros Raros y Manuscritos de la Universidad de Tulane. Tal vez su obra más ambiciosa sea la que dedicó a la escultura de Palenque: cuatro tomos que publicó la Universidad de Princeton entre 1983 y 1991. En el centenario de su nacimiento la recordamos publicando aquí un capítulo de sus memorias Never in Fear (The Pre-Columbian Art Research Institute, 2006)

Parole et silence pour l’expression de l’éthique dans La mort est mon métier de Robert Merle
No full textGracias a una atrevida y original focalización de la narración desde la primera persona, haciendo de una figura histórica nazi su protagonista y narrador, y a otros recursos estilísticos, basados en la cuidadosa elección de lo dicho y lo omitido, Robert Merle muestra en La mort est mon métier cómo la «solución final del problema judío» hitleriana no fue una masacre organizada por unos individuos sanguinarios o vengativos, sino una «dura tarea» ejercida por un conjunto de seres deshumanizados para quienes el honor (y la moral) estribaba en la absoluta entrega de sí mismos a la ciega obediencia a sus superiores.Thanks to a daring and original exercise of focusing the narrative in first person, Robert Merle makes a historical Nazi the hero and narrator of his novel La mort est mon métier. Adding to this fact a careful choice of what is said and what is omitted, the author shows that the “final solution to the Jewish problem” by Hitler was not a massacre organized by some bloodthirsty or revengeful individuals, but a «hard task» accomplished by a group of dehumanized beings for whom the honor –and morals– consisted of total dedication to blind obedience to their superiors

Evidence of multi-phase Cretaceous to Quaternary alkaline magmatism on Tore-Madeira Rise and neighbouring seamounts from Ar-40/Ar-39 ages
No full textThe Tore-Madeira Rise is a seamount chain located 300 km off the Portugal and Morocco coasts attributed to hotspot activity. U-Pb ages of lavas from the northern and central Tore-Madeira Rise range between 103 and 80.5 Ma whereas 40Ar/39Ar ages from the central and southern Tore-Madeira Rise yield ages ranging from 94.5 to 0.5 Ma. We performed new 40Ar/39Ar measurements to better understand the geodynamic history of the Tore-Madeira Rise. Plagioclase ages from the Bikini Bottom and Torillon seamounts suggest ages of >90 Ma and ≥60 Ma, respectively. Amphiboles from the Seine seamount yield an age of 24.0 ± 0.8 Ma. Biotites from lavas of the Ashton seamount give ages of 97.4 ± 1.1 Ma and 97.8 ± 1.1 Ma. The geochronological database available on the Tore-Madeira Rise has been filtered on statistical criteria to eliminate unreliable ages. The resulting database reveals three pulses of alkaline magmatism on the Tore-Madeira Rise at 103-80.5 Ma, at c. 68 Ma and between 30 Ma and the present...
Should all Soldiers be Sensation Seekers? The role of Personality in the Context of Operational Deployments
No full textShould all Soldiers be Sensation Seekers? The role of Personality in the Context of Operational DeploymentsThesis presented by Merle Parmak to obtain the degree of PhD. in Psychology and in Social and Military Sciences, 2011Supervisors: Prof. Dr. Martin Euwema and Prof. Dr. Jacques Mylle In this dissertation individual differences of soldiers psychological adaptation in a military task environment are explored. To better understand the role of personality in soldiers psychological well-being in the context of operational deployments, the dissertation takes its starting point in an interactionistic approach, the Person x Environment (P x E) theory (Lewin, 1935). The environment in operational deployments can be characterized by elevated risks and unpredictable incidents, but also by unquestionable regulations, tightly organised life and tedious tasks and duties. Being simultaneously present, these contradictive conditions chaos and order constitute a challenge for soldiers psychological adaptability. Although soldiers in general manage to adapt, there are those whose personality-based needs are less met by the reality of a particular deployment, and whose mental persistence[1] is more challenging to maintain. The author conducted a series of studies to explore the role of personality, more specifically the role of two narrow traits, Sensation Seeking and Need for Structure, in the psychological adaptability of Estonian soldiers deployed to the Helmand province, in Afghanistan, as part of NATOs International Security Assistance Force (ISAF). Verifying the relevance of P x E fit theory in the context of operational deployments, authors findings contribute to a field of performance research, illustrating the need of an interactional approach studying performers mental persistence in a challenging environment. We have demonstrated the importance of considering not only skills (trainable) and abilities (identifiable) of performing individuals, but also their personality-based needs that may interfere with the outcome of interest. Based on the conclusions of the dissertation, a targeted approach in military training and post-deployment programs is encouraged. As an example, a behavioural modelling technique and simulations are suggested to prepare military personnel for complex operations in contemporary environments. In addition, Third Location Decompression programs are introduced to help their transition from the operational environment back to normal life. In Chapter 1 the author explains the theoretical ground of the research and formulates the research questions. In Chapter 2, the first empirical study is presented, in which the author demonstrates that soldiers with different personality profiles perceive and evaluate the environment and tasks in different ways. Chapter 3 describes the second empirical study, in which the author reports that soldiers are normally able to adapt their personality-based needs to the environmental demands. Chapter 4 illustrates how the soldiers personality profile is related to the difficulty in adapting to the realities of deployment. In Chapter 5, the general discussion, the author describes the relevance of results in terms of theoretical and practical implications. Summary of the main findings: The two studied personality predispositions sensation seeking and need for structure influence the perceived situational structure of a task in a military environment in terms of riskiness and predictability (Ch. 2); Reflecting the operational reality in terms of increased levels of risks and restrictions, an adjustment in the expression of personality-based needs, namely in Sensation Seeking and in Need for Structure is observable (Ch. 3);Soldiers, whose personal predispositions are corresponding to the reality of deployment, namely soldiers who do like a well-ordered environment and have at least a moderate need for sensations, are the least likely to become psychologically influenced negatively by the deployment; i.e. showing the smallest decrease in well-being (Ch. 4). [1] Defined from a motivational perspective (Bandura, 1989, 1991) in terms of ones willingness or a motivational urge to intensity his efforts and persistence of exertion in this particular environment.status: Publishe
“I Could Turn Viper Tomorrow”: Challenging Reproductive Futurism in Merle Collins’s The Colour of Forgetting
No full textGrenadian author Merle Collins has talked in an interview about the collective optimism felt about the future after the Grenadian Revolution of 1979, when the Grenada United Labour Party government was overthrown by the New Jewel Movement (NJM), a Black Power organization that turned into a Marxist political party. This event was seen as a turning point, cementing Grenada’s status as an independent postcolonial country after Britain relinquished the territory in 1974. Collins describes the affection felt for the new Prime Minister, a young revolutionary called Maurice Bishop, in terms of his rapport across generations of ordinary Grenadians, epitomized by a famous photograph of an older woman touching the young Premier’s face (Scott, “Fragility of Memory” 105). The image symbolizes the confection of youth and old age as a postcolonial political stratagem wherein a beneficent grandmother figure nurtures the hope that revolutionary black youth represents.
Collins reflects on the popular perception that Bishop was an approachable and sympathetic agent of change: “‘De boy nice, he nice, all behind he head nice!’ [Everything is nice, good or attractive about him] Dah’s ting you hear. So you think about the body, and how people view the man, the individual” (Scott, “Fragility of Memory” 105). Collins draws on her memories of collective utterance to link revolutionary legitimacy and masculine youthfulness. Bishop is called a ‘boy’ – instead of the British university-educated, Marxist activist he was – implying that his political appeal was accentuated by his youthfulness. Throughout the rest of the interview Collins repeatedly references how young people and students were at the forefront of the NJM movement in resistance to the former Prime Minister Eric Gairy’s ancien régime, which was characterized by longstanding incumbents, corruption, and violent suppression of opposition both before and after Grenada was granted independence (Scott, “Fragility of Memory” 99, 102; also see Meeks 138–48). According to Collins’s testimony, Bishop’s youth and masculine vigour propelled the New Jewel Movement’s popularity. He seems to embody the NJM’s motto, devised by the Grenadian Carnival calypsonian Lord Melody, of “forward ever and backward never.” The interview subtly delineates a distinction between gendered and aged bodies within Grenada’s postcolonial politics
Occurrence of inherited supra-subduction zone mantle in the oceanic lithosphere as inferred from mantle xenoliths from Dragon Seamount (southern Tore–Madeira Rise)
No full textSpinel-bearing peridotite and pyroxenite xenoliths dredged from the Dragon Seamount (southern Tore–Madeira Rise, West Iberia and Morocco margin) give an insight into the composition of the underlying lithosphere. These xenoliths are devoid of evidence of strong host lava–peridotite interaction and re-equilibration or late impregnation in the plagioclase facies. The spinels and pyroxenes from the Dragon peridotites have compositions distinct from those of both lherzolites and harzburgites from the Iberia margin and the Mid-Atlantic Ridge. They display a highly depleted composition, in particular, high Cr-number, up to 0.63 in the spinels, consistent with a melting degree between 12 and 19%. Because of the strong chemical similarities between the Tore–Madeira Rise, Newfoundland peridotites, and peridotites from supra-subduction zones, we propose that the Dragon peridotites formed in a similar context. The pyroxenites display a cumulate texture and are probably a high-temperature–high-pressure cumulate formed by fractional crystallization from a melt. The Tore–Madeira Rise peridotites may represent a former mantle wedge in an oceanic arc, later included into the continental lithosphere and finally tectonically disseminated within the lithosphere during the rifting of the Newfoundland–Iberia continental lithosphere. As a consequence, rifting processes may produce heterogeneities in the oceanic lithosphere and influence isotopic compositions of ocean island basalt-type lavas during plume–lithosphere interactions, as inferred for the southern Tore–Madeira Rise
Geochronology of the Tore-Madeira Rise seamounts and surrounding areas: a review
No full text© 2018 Geological Society of Australia We present new 40 Ar/ 39 Ar data for two of the Tore-Madeira Rise (TMR) volcanic seamounts. A sample from Tore East seamount on the northern part of the TMR yielded an ultra-precise age of 80.50 ± 0.13 Ma (2s) that is similar within uncertainties to a published age obtained by U–Pb TIMS technique on titanites and zircons extracted from Tore NW seamount. Another sample from Isabelle seamount, located on the southern part of the TMR failed to produce a plateau age but yielded a minimum age estimate of > 85 Ma. We filtered the published ages available on the TMR, the surrounding seamounts and the massifs of southwest Portugal to better understand the origin of this magmatic province. Together with this dataset, our new data suggest that:(1) a hypothetical Madeira hot-spot track spanning from Serra de Monchique on the continent to Madeira Archipelago is difficult to reconcile with the occurrence of several seamounts geographically located within or very close to this alleged hot-spot track yet being much older than the age predicted by the age trend.(2) The geographical distribution and age pattern of the TMR and surrounding areas magmatism are still best explained by the interaction of a mantle melting anomaly emitting magma pulses and the different motion phases of the Iberia plate since 103 Ma
Proterozoic to Mesozoic evolution of North-West Africa and Peri-Gondwana microplates: Detrital zircon ages from Morocco and Canada
No full text© 2017 Elsevier B.V. The complex history of assemblage and disruption of continental plates surrounding the Atlantic Ocean is in part recorded by the distribution of detrital zircon ages entrained in continental sedimentary strata from Morocco (Central High Atlas and Argana basins) and Canada (Grand Manan Island, New Brunswick). Here we investigate detrital zircon from the latest Triassic (ca. 202 Ma) sedimentary strata directly underlying lava flows of the Central Atlantic magmatic province or interlayered within them. SHRIMP (Sensitive High-Resolution Ion MicroProbe) and LA-ICP-MS (Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry) U–Pb ages for zircon range from Paleozoic to Archean with a dominant Neoproterozoic peak, and significant amounts of ca. 2 Ga zircon. These ages suggest a prevailing West African (Gondwanan) provenance at all sampling sites. Notably, the Paleoproterozoic zircon population is particularly abundant in central Morocco, north of the High Atlas chain, suggesting the presence of Eburnean-aged rocks in this part of the country, which is consistent with recent geochronologic data from outcropping rocks. Minor amounts of late Mesoproterozoic and early Neoproterozoic zircon ages (ca. 1.1–0.9 Ga) in Moroccan samples are more difficult to interpret. A provenance from Avalonia or Amazonia, as proposed by previous studies is not supported by the age distributions observed here. An involvement of more distal source regions, possibly located in north-eastern Africa (Arabian Nubian Shield) would instead be possible. Paleozoic zircon ages are abundant in the Canadian sample, pointing to a significant contribution from Hercynian aged source rocks. Such a signal is nearly absent in the Moroccan samples, suggesting that zircon-bearing Hercynian granitic rocks of the Moroccan Meseta block were not yet outcropping at ca. 200 Ma. The only Moroccan samples that yield Paleozoic zircon ages are those interlayered within the CAMP lavas, suggesting an increased dismantling (i.e. uplift) of the Hercynian chain during emplacement of CAMP lava flows, combined with subsidence of the volcanic grabens
