Late-Holocene climatic variability south of the Alps as recorded by lake-level fluctuations at Lake Ledro, Trentino, Italy

International audienceA lake-level record for the late Holocene at Lake Ledro (Trentino, northeastern Italy) is presented. It is based on the sediment and pollen analysis of a 1.75 m high stratigraphic section observed on the southern shore (site Ledro I) and a 3.2 m long sediment core taken from a littoral mire on the southeastern shore (site Ledro II). The chronology is derived from 15 radiocarbon dates and pollen stratigraphy. The late-Holocene composite record established from these two sediment sequences gives evidence of centennial-scale fluctuations with highstands at c. 3400, 2600, 1700, 1200 and 400 cal. BP, in agreement with various palaeohydro-logical records established in central and northern Italy, as well as north of the Alps. In addition, high lake-level conditions at c. 2000 cal. BP may be the equivalent of stronger river discharge observed at the same time in Central Italy's rivers. In agreement with the lake-level record of Accesa (Tuscany), the Ledro record also suggests a relatively complex palaeohydrological pattern for the period around 4000 cal. BP. On a millennial scale, sediment hiatuses observed in the lower part of the Ledro I sediment sequence indicate that, except for a high-stand occurring just after 7500 cal. BP, lower lake levels generally prevailed rather before c. 4000 cal. BP than afterwards. Finally, the lake-level data obtained at Lake Ledro indicate that the relative continuity of settlements in humid areas of northern Italy during the Bronze Age (in contrast to their general abandonment north of the Alps between c. 3450 and 3150 cal. BP), does not reflect different regional patterns of climatic and palaeohy-drological conditions. In contrast, the rise in lake level dated to c. 3400 cal. BP at Ledro appears to coincide with a worldwide climate reversal, observed in both the hemispheres, while palaeoenvironmental and archaeological data collected at Lake Ledro may suggest, as a working hypothesis, a relative emancipation of proto-historic societies from climatic conditions

Proportion and number of upper-extremity musculoskeletal disorders attributable to the combined effect of biomechanical and psychosocial risk factors in a working population

The objective of this paper is to assess the combined effect of occupational biomechanical and psychosocial risk factors on the incidence of work-related upper-extremity musculoskeletal disorders (UEMSDs) and estimate the proportion and number of incident cases attributable to these risk factors in a working population. Using data from the French COSALI (COhorte des SAlariés LIgériens) cohort (enrolment phase: 2002-2005; follow-up phase: 2007-2010), a complete case analysis including 1246 workers (59% men, mean age: 38 years ± 8.6 at baseline) was performed. All participants underwent a standardized clinical examination at enrolment and 1611 workers were re-examined at follow-up. Population attributable fractions and the number of UEMSD cases attributable to occupational risk factors were calculated. During follow-up, 139 UEMSD cases were diagnosed, representing an estimated 129,320 projected incident UEMSD cases in the working population. After adjusting for personal factors, in model 1, 8664 cases (6.7%) were attributable to low social support, 19,010 (14.7%) to high physical exertion, and 20,443 (15.8%) to co-exposure to both factors. In model 2, 16,294 (12.6%) cases were attributable to low social support, 6983 (5.4%) to posture with arms above shoulder level, and 5043 (3.9%) to co-exposure to both factors. Our findings suggest that many cases of UEMSD could be potentially prevented by multidimensional interventions aimed at reducing exposure to high physical exertion and improving social support at work

Du minerai au métal et du XIe au XVIIIe siècle : le carreau Sainte-Barbe, un site central dans la production minière de l'Altenberg (Sainte-Marie-aux-Mines, France)

International audienceDůl Sainte-Barbe se nachází ve střední části pohoří Altenberg. Tento důlní segment, nepřetržitě využívaný mezi karolinským obdobím a 17. stoletím, byl proslulý kvůli produkci olova a stříbra. Archeologické průzkumy na hlušině Sainte-Barbe jsou prováděny od roku 2011. Odhalilo se několik fází aktivity i všechny kroky provozního řetězce produkce olova a stříbra. Jedna halda strusky pochází z 11.-12. století a byla vykopána jedna zpracovatelská dílna z 15. století. Tato studie se zaměřuje na kovárnu, halu na skladování rudy a dům ze 16. století. Na základě velikosti své infrastruktury se zdá, že lokalita Sainte-Barbe sloužila zejména v tomto období jako technické centrum pro okolní doly. Během předchozího století lokalita hrála emblematickou roli v pozorování důležité technické změny ve zpracování rud, doprovázeno globálním vývojem provozních procesů v Sainte-Marie-aux--Mines. V důsledku toho provoz upravování rud byl posunut ze svahů na úpatí hor, do blízkosti řek.The Sainte-Barbe mine is located in the middle part of the Altenberg mountain range. This mining sector, continuously exploited between the Carolingian times and the 17 th c. was renowed for its lead and silver production. Archaeological investigations on the Sainte-Barbe tailing have been led since 2011. Several phases of activity were revealed, as well as all the steps of the lead-silver production chaîne opératoire. A slag heap dates from the 11 th -12 th c., an ore processing workshop from the 15 th c. has been excavated and the current work focuses on a forge, an ore storage hall and a house from the 16 th c. Especially during this period, the Sainte-Barbe site seems to have served as a technical centre for surrounding mines, due to the size of its infrastructures. During the previous century, the site had an emblematic role for the observation of an important technical modification in ore processing. This is concomitant with a global evolution in the operating processes in Sainte-Marie-aux-Mines. As a consequence, ore treatment operations left the mountain slopes and took place at its foot, close to the rivers

Organisation of the mining exploitation on the Altenberg medieval sector (Sainte-Marie-aux-Mines; France: the mine "Sainte-Barbe", an emblematic place

International audienceThe Altenberg is one of the three mining sectors in Sainte-Marie-aux-Mines (Vosges, France). It is the only one which was exploited before the Modern Age: it has been demonstrated that the mining exploitation did not stop from the 9th c. to the 17th c. Hundreds of archaeological sites can be found along the 4 km vein system (galena, tetrahedrite): remains of ancient mines, workshops and houses. Among them, in the middle of the sector, the mine Sainte-Barbe is both a point of convergence for surroundings exploitations and a representative example of the Altenberg evolution. The importance of the production in this mine can surely explain the development of infrastructure facilities used by several extraction sites around. Moreover, the 11th-12th c. smelting place, the 15th c. ore dressing place and the 16th c. smith show the increasing distance between mines and workshops, which are progressively set at the foot of the slopes, near the rivers
