Making waves: The Royal Navy's management of invention and innovation in steam shipping, 1815–1832 1

Abstract

This paper explores the sources of invention and innovation in steam shipping, the distribution of funding and risk between the state and the private sector, and the Royal Navy's management of innovation, during the experimental period of steam power's adoption at sea. It identifies two intersecting channels through which steam‐related innovations reached the Royal Navy. First, “packages” of innovations were embedded in the marine engines that were commissioned by the Navy from private engine‐making firms. Secondly, the Navy was spontaneously offered a gamut of ideas and inventions, which varied enormously both in potential importance and in degree of development. Although the mechanisms for dealing with these two channels were different, the end result was much the same ‐ in minimizing both the expense and the risk borne by the public sector. It was principally the private sector that was funding scientific and technological development in this sphere. Recognizing its own lack of expertise and consequent hazard, the Navy Board was developing a systematic yet flexible method of assessing steam‐related inventions ‐ which appears to have served it well.     

The Sense of Oklahomaness: Contributions of Psychogeography to the Study of American Culture

What the authors are calling “Oklahomaness” is meant to evoke that (psychogeographic) feeling of what it is to be Oklahoman, both as experienced by Oklahomans and by those outside Oklahoma as well. While this study will delineate Oklahomaness per se, the authors hope that it will stimulate the reader's imagination so that the reader might take from it a new way of looking at, and feeling into, the human sculpting of natural and social space.     

Between Horror and Hope: Gladiator’s Blood as a Cure for Epileptics in Ancient Medicine

Between the first and the sixth century a single theological and several medical authors reported on the consumption of gladiator’s blood or liver to cure epileptics. The origins of the sacred or apoplectic properties of blood of a slain gladiator, likely lie in Etruscan funeral rites. Although the influence of this religious background faded during the Roman Republic, the magical use of gladiators’ blood continued for centuries. After the prohibition of gladiatorial combat in about 400 AD, an executed individual (particularly had he been beheaded) became the “legitimate” successor to the gladiator. Occasional indications in early modern textbooks on medicine as well as reports in the popular literature of the 19th and early 20th century document the existence of this ancient magical practice until modern times. Spontaneous recovery of some forms of epilepsy may be responsible for the illusion of therapeutic effectiveness and for the confirming statements by physicians who have commented on this cure.     

Medieval Descriptions and Doctrines of Stroke: Preliminary Analysis of Select Sources. Part III: Multiplying Speculations – The High and Late Middle Ages (1000–1450)

By analyzing a body of texts compiled by various medical authors from the 11th to the 15th century, four basic developments can be noted: (1) From the beginning of the eleventh century the reception, translation and assimilation of Arabian and arabicized ancient texts became the ultimate goal of Western medicine (Constantine the African, Arnald of Villanova, et al.). Concepts of stroke were consequently guided by textual tradition, not by observation. (2) Scholastic speculations about different aspects of apoplexy, especially those concerning its origins, were numerous (Johannes Platearius, Batholomaeus Salernitanus, Pietro d'Abano, Giacomo da Forlì). Although most medieval physicians used the ancient doctrine of the four humors as model and explanation, opinions differed in many ways. (3) Attempts developed to present a simple outline of the etiology, the prognosis, and the treatment of the disease (Gilbertus Anglicus, Bernard of Gordon, John of Gaddesden). (4) Although lacking in originality, many of these writers nevertheless achieved a certain uniformity in presenting main topics, thus setting the standard for later practitioners.     

A Late Holocene Tsunami at Basta Voe,Yell, Shetland Isles

A distinctive sand layer enclosed within Holocene peat is described from Basta Voe, Isle of Yell, Shetland Isles. The sand layer, that can be traced considerable distances inland and up to a maximum altitude of c. + 9 m OD, is here interpreted as having been deposited by a former tsunami. AMS dating appears to indicate that the tsunami occurred between 1300 – 1570 cal years BP. At present, the tsunami has no known source mechanism although the most likely mechanism is thought to have been an offshore slump or slide. The available information would presently seem to indicate that this tsunami was restricted to the eastern coastline of Shetland. The relatively young age of this inferred tsunami is of considerable importance to planners and engineers concerned with estimating coastal flood frequency and magnitude.     

REGIONAL POLICY ANALYSIS IN A SIMPLE GENERAL EQUILIBRIUM MODEL WITH VERTICAL LINKAGES*

ABSTRACT The paper presents a simple three‐region, two‐sector general equilibrium model that is used for analyzing the effect of regional tax policies aimed at combat depopulation. The model includes exogenous asymmetry in terms of transport costs as well as a vertical industry structure that can account for endogenous location development in order to distinguish between the effects of “first nature” and “second nature” on the required subsidy for meeting the population policy target.     

Errichtung und Zurechnung von Ressortforschungseinrichtungen. Eine Frage des Bedarfs an wissenschaftlicher Expertise?

The Constitution and Attribution of Government Research Agencies. A Matter of Need for Science‐generated Policy Knowledge? Government research agencies are a form of extra‐university research institutions. In contrast to other extra‐university research facilities they are subordinate to and financed by respective German governmental departments. As their mission they provide science‐generated information, services, and monitoring to support the governmental departments. In science studies researchers proclaim a rigid association between the installation, attribution, and development of government research agencies and the increasing need for science‐generated policy knowledge. The article examines this assumed association based on the personal, institutional, financial, and mission specific development of government research agencies between the years 1965 and 2005. According to the results the expansion of government research agencies stagnates – like science in general.     

Tools for Predicting Damage to Archaeological Sites Caused by One-Dimensional Loading

Tools are developed to predict damage to archaeological remains caused by the construction of line infrastructure on soft soil. They are based on numerical modelling and laboratory testing supported by X-ray microcomputed tomographic observations, and micromorphological analyses of thin sections. They have been validated for one-dimensional (1D) loading at two sites in the Netherlands where soil has been placed on top of organic layers rich in ecofacts and overlaying Pleistocene sands.

Numerical prediction of the deformation of soft layers underneath an embankment remains a challenge for geo-technical engineers. Errors on surface settlement prediction reach ±15% of the measured total settlement.

Laboratory observations show that vulnerable artefacts can get crushed when packed loosely in pure assemblies under 1D loading equivalent to less than 5 m of sand. Fragmentation is assimilated to loss of archaeological value as it compromises recovery during sieving. Embedment in a sandy or a very compressible organic matrix has a beneficial effect on the resistance of ecofacts. Embedded ecofacts can resist a load of more than 12 m of sand. Flattening and re-orientation of soft plant remains occur during 1D loading without microscopic damage of tissues.     

Humeral morphology of the early Eocene mekosuchine crocodylian Kambara from the Tingamarra Local Fauna southeastern Queensland,Australia

Stein, M., Salisbury, S.W., Hand, S.J., Archer, M. & Godthelp, H., December 2012. Humeral morphology of the early Eocene mekosuchine crocodylian Kambara from the Tingamarra Local Fauna southeastern Queensland, Australia. Alcheringa 36, 473–486. ISSN 0311-5518.

Mekosuchines (Crocodylia; Crocodyloidea) were a clade of crocodylians endemic to Australia and the South Pacific that underwent radiation during the Cenozoic. Numerous questions about mekosuchine palaeoecology remain unanswered. Tantalizing among these is the possibility that some mekosuchines were primarily terrestrial. To date, studies of mekosuchines have focused mainly on the cranium. However, the morphological signal for terrestriality is more likely to be found in the postcranial skeleton. Here, we present a comparative morphological study of fossil humeri referable to Kambara from the early Eocene Tingamara Local Fauna, Murgon, southeastern Queensland. The humeri of Kambara do not show the torsion between the proximal and distal extremity seen in extant crocodylians, illustrated here with Crocodylus porosus and Crocodylus johnstoni. They also differ in the structure of the medial and lateral condyles of the distal extremity. When the effects of these features on musculature and articulation are considered, it appears that the forelimb of Kambara could have facilitated a greater force at the glenohumeral joint and possibly swung the lower forelimb faster with a greater arc of motion than Australia's extant crocodylians. This is conducive to an improved capacity for both terrestrial locomotion and paraxial swimming. Although the former case suggests that Kambara may not have been as closely tied to water as extant crocodylians, it is unusual given the typically broad rostra of the cranium. Among crocodylians this is a common characteristic of semi-aquatic ambush predators. This study shows the utility of the postcranial skeleton in interpreting crocodylian palaeoecology.
