Until recently the role of the public drinking house has been approached from elitist, folkloric and anecdotal perspectives. The work of a new generation of social historians, however, has raised the tavern’s profile in the academic consciousness and confirmed its position within the mainstream of social and cultural history. It is now recognized that an understanding of the centrality of public drinking to the development of both elite and popular culture is vital to studies of social behaviour. The study of taverns has also been at the forefront of emerging interest in the history of consumption and material culture, and has contributed to a richer understanding of economic history. Constructions of gender and identity are also visible through research into the patterns of behaviour and discourse in and around the public house. This four-volume reset edition presents a wide-ranging collection of primary sources which uncover the language and behaviour of local and state authorities, of peasants and town-dwellers, and of drinking companions and irate wives. The documents are translated and set in their social and historical context, providing a multidisciplinary collection that will be of great importance to scholars of all areas of social and cultural history of the early modern period. The vast majority of this material is published here for the first time, ensuring that the collection will open up new avenues of research. Volume 1 draws heavily from the Parisian police archives and includes inspectors’ reports, complaints by the general public and details of court cases to build a picture of drinking in early modern France. Volumes 2 and 3 address public drinking in the Holy Roman Empire through a variety of chronicles, civic ordinances, court records, travel reports and surveys of public houses. Volume 4 locates taverns within a broader analysis of America’s public houses, drawing on visual material as well as journal entries, business reports and newspaper articles. Each volume is accompanied by editorial introductions and is annotated to provide readers with a high-quality resource of scholarly material.

To increase the sparse knowledge of long-term Southern Hemisphere (SH) climate variability, we assess an ensemble of 4 transient simulations over the last 500 yr performed with a state-of-the-art atmosphere ocean general circulation model. The model is forced with reconstructions of solar irradiance, greenhouse gas (GHG) and volcanic aerosol concentrations. A 1990 control simulation shows that the model is able to represent the Southern Annular Mode (SAM), and to some extent the South Pacific Dipole (SPD) and the Zonal Wave 3 (ZW3). During the past 500 yr we find that SPD and ZW3 variability remain stable, whereas SAM shows a significant shift towards its positive state during the 20th century. Regional temperatures over South America are strongly influenced by changing both GHG concentrations and volcanic eruptions, whereas precipitation shows no significant response to the varying external forcing. For temperature this stands in contrast to proxy records, suggesting that SH climate is dominated by internal variability rather than external forcing. The underlying dynamics of the temperature changes generally point to a combination of several modes, thus, hampering the possibilities of regional reconstructing the modes from proxy records. The linear imprint of the external forcing is as expected, i.e. a warming for increase in the combined solar and GHG forcing and a cooling after volcanic eruptions. Dynamically, only the increase in SAM with increased combined forcing is simulated.

OBJECTIVE: To investigate effects of isoflurane at approximately the minimum alveolar concentration (MAC) on the nociceptive withdrawal reflex (NWR) of the forelimb of ponies as a method for quantifying anesthetic potency. ANIMALS: 7 healthy adult Shetland ponies. PROCEDURE: Individual MAC (iMAC) for isoflurane was determined for each pony. Then, effects of isoflurane administered at 0.85, 0.95, and 1.05 iMAC on the NWR were assessed. At each concentration, the NWR threshold was defined electromyographically for the common digital extensor and deltoid muscles by stimulating the digital nerve; additional electrical stimulations (3, 5, 10, 20, 30, and 40 mA) were delivered, and the evoked activity was recorded and analyzed. After the end of anesthesia, the NWR threshold was assessed in standing ponies. RESULTS: Mean +/- SD MAC of isoflurane was 1.0 +/- 0.2%. The NWR thresholds for both muscles increased significantly in a concentration-dependent manner during anesthesia, whereas they decreased in awake ponies. Significantly higher thresholds were found for the deltoid muscle, compared with thresholds for the common digital extensor muscle, in anesthetized ponies. At each iMAC tested, amplitudes of the reflex responses from both muscles increased as stimulus intensities increased from 3 to 40 mA. A concentration-dependent depression of evoked reflexes with reduction in slopes of the stimulus-response functions was detected. CONCLUSIONS AND CLINICAL RELEVANCE: Anesthetic-induced changes in sensory-motor processing in ponies anesthetized with isoflurane at concentrations of approximately 1.0 MAC can be detected by assessment of NWR. This method will permit comparison of effects of inhaled anesthetics or anesthetic combinations on spinal processing in equids.
