Recent theoretical accounts of verbal and visuo-spatial short-term memory (STM) have proposed the existence of domain-general mechanisms for the maintenance of serial order information. These accounts are based on the observation of similar behavioural effects across several modalities, such as temporal grouping effects. Across two experiments, the present study aimed at extending these findings, by exploring a STM modality that has received little interest so far, STM for musical information. Given its inherent rhythmic, temporal and serial organisation, the musical domain is of interest for investigating serial order STM processes such as temporal grouping. In Experiment 1, the data did not allow to determine the presence or the absence of temporal grouping effects. In Experiment 2, we observed that temporal grouping of tone sequences during encoding improves short-term recognition for serially presented probe tones. Furthermore, the serial position curves included micro-primacy and micro-recency effects, which are the hallmark characteristic of temporal grouping. Our results suggest that the encoding of serial order information in musical STM may be supported by temporal positional coding mechanisms similar to those reported in the verbal domain. [less ▲]

Regional climate models (RCMs) are suitable numerical tools to study the surface mass balance (SMB) of the wide polar ice sheets due to their high spatial resolution and polar-adapted physics. Nonetheless, RCMs are driven at their boundaries and over the ocean by reanalysis or global climate model (GCM) products and are thus influenced by potential biases in these large-scale fields. These biases can be significant for both the atmosphere and the sea surface conditions (i.e. sea ice concentration and sea surface temperature). With the RCM MAR, a set of sensitivity experiments has been realized to assess the direct response of the SMB of the Antarctic ice sheet to oceanic perturbations. MAR is forced by ERA-Interim and anomalies based on mean GCM biases are introduced in sea surface conditions. Results show significant increases (decreases) of liquid and solid precipitation due to biases related to warm (cold) oceans. As precipitation is mainly caused by low-pressure systems that intrude into the continent and do not penetrate far inland, coastal areas are more sensitive than inland regions. Furthermore, warm ocean representative biases lead to anomalies as large as anomalies simulated by other RCMs or GCMs for the end of the 21st century. [less ▲]

The so-called "Map of the gold mines" (P. Turin Cat. 1879) is among the most famous papyri of the Turin collection (and of ancient Egypt as a whole), but it has never been properly published, nor systematically studied up until today. Most of the egyptological attention was indeed captured by the ‘map’ side (e.g., Goyon 1949; Harrell & Brown 1992), but the verso of the document, which contains many hieratic texts belonging to different genres, has not been examined thoroughly (exceptions are Janssen 1994 and Hovestreydt 1997 for col. 1-2 of frag. A, vo). As a prelude to a complete edition of this papyrus, the goal of this lecture is threefold. First, we provide an overview of history of this papyrus since its acquisition in 1824 (as part of the Drovetti collection), and we discuss various scholarly interpretations. In a second part, we focus on the map, discussing some unacknowledged iconic features as well as its topographical and geological significance. The third section of the talk is devoted to the texts found on the verso, to the relationship between these texts and the map, and to the identification of the hands and scribes who worked on this papyrus. We conclude with a discussion of the scribal practices — at Deir el-Medina and beyond — that led to the creation of such an exceptional document. [less ▲]

Résumé - Depuis les années 2000, la vie politique cambodgienne est marquée par des conflits majeurs provoqués par la destruction de communs fonciers, ruraux et urbains. Ces conflits jaillissent dans un contexte où la violence et les relations clientélistes propres à l’exercice du pouvoir d’Etat cambodgien limitent la formation de contre-pouvoirs. Des espaces de résistance existent néanmoins et les possibilités d’internet les transforment ou les amplifient. A travers les conflits fonciers, cet article examine les mobilisations du web et montre qu’elles apportent une dimension informationnelle aux dynamiques sociales de protection des communs fonciers. La mise à disposition de données et informations foncières sur internet par des acteurs de la société civile bouscule le rôle central de l’Etat en la matière. Toutefois, le lien entre les interventions du numérique et la gouvernance foncière ne va pas de soi et reste une piste à explorer. Abstract - Since the years 2000, political life in Cambodia has been deeply marked by land conflicts, brought about by the destruction of rural and urban commons. These conflicts occur in a context where violence and patronage, which are at the core of Cambodian State formation practises, limit approaches to counter power. However, spaces of resistance exist and are actively transformed by the internet. Through the prism of land conflicts, this article examines how different mobilizations of the Web bring an informational dimension to the social dynamics of protecting land-based commons. The release of land-related data and information on the internet by civil society actors shakes up the central role of the State as data gatekeeper. Yet, the link between these intervention on the Web and land governance is not obvious and remain to be explored. Keywords - Land tenure ; Commons ; Internet ; Governance ; Conflict [less ▲]

The use of fire is essential for the preparation of hafting adhesives; both are suggested to be a proxy for distinguishing the technological expertise and complex cognition among Palaeolithic populations. While use of fire has been argued to exist from about 1.0 Ma onwards, evidence for adhesives in the Palaeolithic record is rare and fragmented. In spite of the close link between fire places and adhesives, no study has ever focussed on examining the impact of heat on adhesive deposition and preservation. This paper discusses the results of a combustion experiment that was undertaken to understand the impact of heat exposure on hafting adhesives. The results have significant implications for archaeological interpretations. Deposition in or near a fire proves to severely impact the types of residues that preserve on a stone tool. The vertically transferred heat is responsible for the loss of adhesives but also for the incidental production of adhesives and their deposition on stone tools. It can be hypothesised that the rare survival of adhesives on archaeological stone tools might not only be the result of direct contact with the fire but also the result of degradation due to heat from overlying fireplaces. If we are to improve our understanding of the preservation of adhesives, it is important to unstand the taphonomic processes that affect these adhesives, in particular heat alteration. [less ▲]

The Late Devonian was affected by major, irreversible changes including two of the most severe biodiversity crises in Earth’s history, the so-called Kellwasser and Hangenberg Events (respectively near the Frasnian – Famennian (F-F) and the Devonian – Carboniferous (D-C) boundaries). Currently, hypotheses for the Late Devonian extinctions include sea-level fluctuations and regression, climate cooling, ocean anoxia, massive volcanism and/or bolide impact. Unfortunately, testing these hypotheses is impaired by a lack of sufficient temporal resolution in paleobiological, tectonic and proxy climate records. Recent advances in astronomical calibration have improved the accuracy of the Frasnian time scale and part of the Famennian. However, the time duration of the Famennian Stage remains poorly constrained. During the Late Devonian, an epieric sea in North-America mid-continent occupied the Illinois Basin where a complete Late Frasnian – Early Carboniferous succession of deep-shelf deposits was archived. A record of this sequence is captured in three overlapping cores (H-30, Sullivan Slough and H-32). The H-30 core section spans the F-F boundary; the Sullivan Slough section spans almost all of the Famennian and the H-32 section sampled spans the D-C boundary. To have the best chance of capturing Milankovitch cycles, 2200 rock samples were collected at minimum 5-cm-interval across the entire sequence. Magnetic susceptibility (MS) was measured on each sample and the preservation of climatic information into the signal was verified through geochemical analyses. To estimate the duration of the Famennian stage, we applied multiple spectral techniques and tuned the MS signal using the highly stable 405 k.y. cycle for Sullivan Slough and the obliquity cycle (34.4 k.y.; Waltham, 2015) for the H-30 and H-32 cores. Based on the correlation between the cores and the tuning, we constructed a Famennian astronomical time scale, which indicates a duration of 13.3 m.y. An uncertainty of ± 0.5 m.y. was calculated to assess the errors raising from the stratigraphic position of the F-F and D-C boundaries, and the 405 k.y. cycle counting error. Our estimate duration is very close to the GTS-2012 duration (Becker, 2012) interpolated from the high-resolution (U/Pb) radiometric ages available for the uppermost Devonian. [less ▲]

The Late Devonian period was affected by major, irreversible changes including two of the most severe biodiversity crises in Earth’s history, the so-called Kellwasser and Hangenberg Events (respectively at the Frasnian – Famennian and the Famennian – Carboniferous boundaries). Currently, hypotheses for the Late Devonian extinctions include sea-level fluctuations and regression, climate cooling, ocean anoxia, massive volcanism and/or bolide impact. Unfortunately, testing these hypotheses is impaired by a lack of sufficient temporal resolution in paleobiological, tectonic and proxy climate records. Recent advances in astronomical dating have improved the accuracy of the Frasnian time scale and part of the Famennian (De Vleeschouwer et al., 2012, 2013). However, the time duration of the Famennian stage remains poorly constrained even though this is the key to understanding cause-and-effect relationships of the Late Devonian greenhouse–icehouse transition and the onset of the end Famennian glaciation that ultimately led to the Hangenberg Event at the Devonian–Carboniferous boundary. During the Late Devonian an epieric sea in mid-continent North America occupied the Illinois Basin onto which a Late Frasnian – Early Carboniferous sequence of deep-shelf deposits was archived. A complete record of this sequence, mainly composed of marl, organic-rich shale, silty-shale and carbonate, is captured in three overlapping cores stored in the Iowa Geological Survey (H-30, Sullivan Slough and H-32). H-30 records the Frasnian-Famennian boundary, the Sullivan Slough covers almost all the Famennian (middle triangularis-upper expansa conodont zones) and H-32 spans the junction between the uppermost Famennian and lowermost Carboniferous. To have the best chance of capturing Milankovitch cycles (long- and short-eccentricity cycles as well as obliquity and precession), 2200 rock samples were collected at 5-cm intervals across the entire sequence. Magnetic susceptibility (MS) was measured on each sample and the preservation of paleoenvironmental/climatic information into the signal was verified through geochemical analyses (Ti, Al, Zr by XRF) and magnetic measurements (low temperature magnetic susceptibility and IRM acquisitions). Correlation and overlap between each core was made using available conodont biostratigraphy and then refined by comparing the trends in the MS and δ13C signals for critical intervals. To estimate the duration of the Famennian stage we applied multiple techniques on the MS signal (multitaper method, evolutive harmonic analysis and adaptive-weighted harmonic F-test). By combining these techniques, we identified highly stable 405-kyr cycles across the Sullivan Slough and the H-32 cores. 405-kyr cycles were not observed in H-30, but 100-kyr cycles were identified. A preliminary estimate of the duration for the Famennian stage using the 405-kyr cycle as chronometer constrains the duration of the Famennian stage to 13 ± 0.4 Myr with an average sedimentation rate of 0.5 cm/kyr across the sequence.
