Surficial deposits, ice movements, and glacial lakes are described for an area of 42 000 square miles in northeastern Ontario. Field studies and air photograph interpretation suggest the following sequence of events. A major fan-shaped advance of an ice mass over the study area. This was followed by the withdrawal of the ice mass from the area and the formation of proglacial lakes. This ablation phase was followed by a minor readvance. Two phases are postulated for this 'Cochrane' readvance. Within the study area, the extent of the glacial lakes and the limits of extension of the Cochrane readvance are postulated. A maximum water plane, location, and maximum elevation of outlet and amount of differential uplift of sediments are postulated for glacial Lake Barlow–Ojibway.

The surficial deposits, ice movements, and glacial lakes are described within an area of 25 000 square miles in northwestern Ontario. Field studies and subsequent interpretation of aerial photographs suggest the existence of two major and one minor ice mass during late Wisconsin glaciation. Movements by the various ice masses are shown and correlated. The extent of several glacial lakes and their drainage channels are described. A reconstruction of the sequence of events, based on morphological features, allows a tentative correlation of Glacial Lake Agassiz in the west with Glacial Lake Minong stages in the Superior basin. A radiocarbon date of 9 380 ± 150 years B.P. (GSC No. 287) was obtained from wood buried in a post-Minong beach.

The surficial deposits, ice movements, and glacial lakes within an area of 34 500 square miles in northeastern Ontario are described. Some of the moraines of the study are tentatively correlated with moraines to the west in the upper peninsula of Michigan, in the Nipigon area, and along the north shore of Lake Superior. The glaciolacustrine deposits and sequence of events in the study area in relation to the glacial features and chronology of the southern Great Lakes basin provide a basis for a partial glacial chronology for the study area. A knowledge of the glacial features of this area further elucidates the integration of movements of two advancing ice lobes, which was observed in northwestern Quebec.

The structure of hydrous amorphous SiO2 is fundamental in order to investigate the effects of water on the physicochemical properties of oxide glasses and magma. The hydrous SiO2 glass with 13 wt.% D2O was synthesized under high-pressure and high-temperature conditions and its structure was investigated by small angle X-ray scattering, X-ray diffraction, and neutron diffraction experiments at pressures of up to 10 GPa and room temperature. This hydrous glass is separated into two phases: a major phase rich in SiO2 and a minor phase rich in D2O molecules distributed as small domains with dimensions of less than 100 Å. Medium-range order of the hydrous glass shrinks compared to the anhydrous SiO2 glass by disruption of SiO4 linkage due to the formation of Si–OD deuterioxyl, while the response of its structure to pressure is almost the same as that of the anhydrous SiO2 glass. Most of D2O molecules are in the small domains and hardly penetrate into the void space in the ring consisting of SiO4 tetrahedra.

The contractile history of muscle can potentiate electrically evoked force production. A link to voluntary force production, related in part to an increase in reflex excitability, has been suggested.Purpose:Our purpose was to quantify the effect of postactivation potentiation on voluntary force production and spinal H-reflex excitability during explosive plantar fexion actions.Methods:Plantar flexor twitch torque, soleus H-reflex amplitudes, and the rate of force development of explosive plantar fexion were measured before and after 4 separate conditioning trials (3 × 5 s maximal contractions).Results:Twitch torque and rate of force production during voluntary explosive plantar flexion were significantly increased (P < .05) while H-reflex amplitudes remained unchanged. Although twitch torque was significantly higher after conditioning, leading to a small increase in the rate of voluntary force production, this was unrelated to changes in reflex excitability.Conclusion:We conclude that postactivation potentiation may result in a minor increase in the rate of voluntary isometric force production that is unrelated to neural excitability.

Radical Shift

This book explores the development of Scottish child protection law from its earliest days in the poor law, tracing the changing assumptions that underlay child protection processes, and the radical shift of emphasis from private (charitable) endeavour to public (local authority) duty. This book looks at the developing legal processes for removing children from abusive or neglectful environments, explores how child offenders and child victims came to be dealt with in the same processes, and examines the reasons why Scots law has managed to continue to cleave its own procedural path in the contemporary world. It explores both processes and outcomes, explaining how the juvenile court evolved into the children’s hearing, and it examines the substantive continuities between the various orders that could be made over children. The regulation of boarding out and fostering of children is compared with the regulation of institutional care, and the evolution of aftercare provisions is explained. The book also offers an analysis of the (dubious) legal basis for the Imperial practice of sending troubled children to the colonies, as part of a deliberate policy of spreading British “stock” across the world. The final chapter traces the origins and statutory control of the practice of adoption of children, from its days as an informal arrangement through its early manifestation as a minor action changing status to its present position as the most radical order that a court of law can make.

Abstract Whenever one reads internal histories of psychology what is covered is the establishment of a lab by Wundt in 1879 as the initiating act and then the breakaway movements of the 20th Century are discussed: Behaviorism, Gestalt Theory, Psychoanalysis, and most recently the Cognitive revival. However, Aron Gurwitsch described a perspective noted by Cassirer and first developed by Malebranche, which dates the founding of psychology at the same time as that of physics in the 17th Century. This external perspective shows the dependency of psychology upon the concepts, methods and procedures of physics and the natural sciences in general up until the present time. Gurwitsch argues that this approach has blocked the growth of psychology and has assured its status as a minor science. He argued that the everyday Lifeworld achievements of subjectivity are the true subject matter of psychology and that a phenomenological approach to subjectivity could give psychology the authenticity it has been forever seeking but never finding as a naturalistic science. Some clarifying thoughts concerning this phenomenologically grounded psychology are offered, especially the role of desire. The assumption of an external perspective toward the history of psychology fostered the insights about psychology’s scientific role.

Ice Conditions

The last glaciation of Fosheim Peninsula is reconstructed on the basis of landform and sediment mapping and associated radiocarbon dates. Ice growth involved the expansion of cirque glaciers and accumulation on upland surfaces that are now ice free. Limited ice buildup, despite lowering of the paleoglaciation level by 700–800 m, is attributed to the hyperaridity of the region during glacial conditions. Marine deposits in formerly submerged basins beyond the ice margins are interpreted to represent (i) sedimentation caused by local ice buildup and marine transgression by 10.6 ka BP, (ii) increased ablation and glacier runoff [Formula: see text]9.5 ka BP, and (iii) marine regression during the Holocene. Holocene marine limit reaches a maximum elevation of approximately 150 m asl along northern Eureka Sound and Greely Fiord and descends southeastwards to 139–142 m asl near the Sawtooth Mountains. A synchronous marine limit is implied where the last ice limit was inland of the sea. The magnitude and pattern of Holocene emergence cannot be fully explained by the glacioisostatic effects of the small ice load during the last glaciation of the region. Deglaciation of the peninsula was underway by 9.5 ka BP; however, local ice caps may have persisted through the wannest period of the Holocene until 6–5 ka BP. This was likely a function of reduced sea ice conditions and increased moisture availability which benefited low-lying coastal icefields, but had negligible effect on interior highland ice caps.

Ancient Geography

The appearance in 1998 of F. E. Romer's English translation of Pomponius Mela's De Chorographia has helped to raise further the profile of this previously rather obscure author. Indeed, since the publication a decade previously of the Budé edition by Alain Silberman, interest in Mela seems to have grown quite steadily. Important contributions in German by Kai Brodersen have widened our appreciation of Mela's place within ancient geography as a whole, and his role within the history of cartography has been the subject of a number of shorter pieces.One element common to all these works, however, is a continuing tendency to disparage both Mela himself and the work he created. This is typified by Romer, for whom Mela was ‘a minor writer, a popularizer, not a first-class geographer’; one ‘shocking reason’ for his choice of genre was simply poor preparation, ‘insufficient for technical writing in geography’. Similar judgements appear in the works of Brodersen and Silberman. Mela's inaccuracies are, for these critics, typical of the wider decline of geography in the Roman period. Perhaps such negative views sprang initially from a sense of frustration: it was counted as one of our author's chief defects that he failed to list many sources for his work. For scholars interested in Quellenforschung it makes poor reading. Yet, quite clearly, the De Chorographia has also been damned by comparison. Mela's work has been held against the best Graeco-Roman learning on geography during antiquity—against Strabo, Ptolemy, or Pliny—and it has usually been found wanting. Set against the achievements of his peers, his work does not stand close scrutiny. Thus, for most scholars, the text has been read as a failed exercise in technical geography, or a markedly inferior document in the wider Graeco-Roman geographical tradition.
