Thomas Graham Brown undertook seminal experiments on the neural control of locomotion between 1910 and 1915. Although elected to the Royal Society in 1927, his locomotion research was largely ignored until the 1960s when it was championed and extended by the distinguished neuroscientist, Anders Lundberg. Puzzlingly, Graham Brown's published research stopped in the 1920s and he became renowned as a mountaineer. In this article, we review his life and multifaceted career, including his active neurological service in WWI. We outline events behind the scenes during his tenure at Cardiff's Institute of Physiology in Wales, UK, including an interview with his technician, Terrence J. Surman, who worked in this institute for over half a century.  相似文献

Ozone amounts in the mesosphere have been determined from limb-scan observations made by the near infra-red channel of the Faza teleradiometer on board the orbital station ‘Salyut-7’ in October and November 1985. Altitude and latitude ozone and atomic oxygen density profiles were deduced. We have observed a secondary maximum of ozone density near 80 km. An error analysis shows that effects of random errors in the data are less than 10% between 45 and 75 km.  相似文献

The establishment of the new magnetic observatory at Charters Towers is described. Hourly values of the magnetic elements are analysed from two data sets (1984–1985 and 1986–1987) to provide solar diurnal variations during different months. These are compared with other stations in Australia and Papua New Guinea to study the behaviour of the focus of the Sq current systems. The unar geomagnetic variations are consistent with other Australian stations. An oceanic lunar tide is detected in the vertical element Z.  相似文献

In this article, we address the international dimension of Stellenbosch University (SU) during the apartheid era, most notably during the academic boycott of South African universities between the early 1960s and the early 1990s. Based on information gathered from the documentary sources of the university and interviews with key role players at the university, the findings of the research will put some of the well-established hypotheses on South Africa’s academic isolation and an increasing localism in higher education during that period into perspective. The article will show that prior to 1990 there were different kinds of international activities going on at SU, despite the academic boycotts.  相似文献

This article is a study of a neglected yet significant French writer on the United States, Louis-Xavier Eyma (1816–76). In the period of the Second Empire (1852–70), Eyma wrote more about the United States than any other author, and was recognised as a reliable and influential guide to US society. What makes his career particularly interesting is that his work defies any simple categorisation. Whilst elements of his writings smack of anti-Americanism, he wrote with admiration about many aspects of US democracy and society. At the same time, he did not belong to the group of liberal writers who, according to some scholars, used praise of the United States as a coded means of criticising repressive government at home. Eyma was a staunch monarchist who opposed the introduction of democracy in his native France. Eyma's career demonstrates the complexity of French attitudes towards the United States, and points towards the need for a comprehensive study of French writing about the United States in the period of the Second Empire.  相似文献

This paper presents the results of inter-disciplinary work drawing on archaeobotanical and archaeometric studies to trace the agroforestry landscape and the supply economy at the vicus of Thamusida in north-west Morocco at the border of the Roman Empire. The available data indicate the self-sufficiency of the settlement in both forestry and agricultural products throughout the period investigated from the end of the 1st century BC to the beginning of the 4th century AD. Charcoal data testify to the presence of a Quercus suber forest in the close surroundings of the site and its exploitation for a variety of forestry products such as timber, fuelwood, cork, and probably also leaves and acorns to feed livestock. The overwhelming presence of Q. suber in the archaeological layer investigated clearly indicates that this forest was under human influence prior to Roman occupation and was already partially degraded. Charred seed and fruit remains suggest that the diet of both troops and civilians was mainly based on locally grown products and that all the inhabitants of the site had access to good cereals such as barley, naked wheats and pulses with large seeds such as horse bean and pea; quality fruits, such as olive and grape, were also produced locally for fresh consumption. Organic residue analyses of the contents of ceramic vessels and plastered vats allowed archaeobotanical data to be complemented, thereby shedding light on some of the imports at Thamusida. Despite the remote location of this settlement, imported goods such as oil and wine were transported here in amphorae from different parts of the Empire.  相似文献

Excavations at the Kraków Spadzista Street (B) site, Poland were conducted over 16 years in which approximately 150 m2 of the site was studied. The radiocarbon dates clustered around 23–24 ky BP, placing the site in the Gravettian cultural complex. In this paper, results from a detailed taphonomic study of faunal remains are discussed in conjunction with previous analyses of stone artefacts and site structure in order to address questions regarding site formation and Gravettian occupation. Up to 1994, ∼9000 bone remains were recovered and it was possible to identify the species and skeletal element for 5860 remains. The site contained bones of seven animal species associated with Pleistocene steppe–tundra habitats. At Kraków Spadzista Street (B), 99% of the faunal remains belong to the woolly mammoth, with other large mammal taxa represented by only isolated bones and teeth. This site yielded the largest number of mammoth bones and most individuals (MNI = 86) ever found in one place in Poland. Kraków Spadzista Street (B) represents a mammoth butchering locality and probably a mammoth hunting site as well. However, it is not yet possible to distinguish the mammoths killed by Gravettian hunters from those that died naturally and then were scavenged by people.  相似文献

The private letter, one of the most representative expressions of mass literacy, was the product of improved postal services and epistolary manuals. In the nineteenth century, which also witnessed the new phenomenon of mass emigration, letter writing became one of the most common practices. This article discusses the correspondence of José Moldes, an Asturian who left Spain for Puerto Rico at the age of fourteen and settled shortly afterwards in Chile. He died in his native Asturias at the age of sixty-one. Throughout these fifty or so years, José wrote letters to keep in contact with members of his family, to control them when he became head of the household or to manage his businesses and investments. About 120 of his letters survived in the Moldes-Barreras family archive, through which we can reconstruct his experiences. The essential characteristics of this epistolary corpus emerge from an analysis of its material and graphic aspects, suggesting the profound influence of immigration on personal writing.  相似文献

In border region studies, the concept of (un)familiarity is applied in empirical studies of consumer culture across borders, illustrating how feelings of unfamiliarity can have an off-putting influence on cross-border interaction (e.g. because of dislike of or lack of attraction to the other side) at the same time as it can be an incentive for people living at borders to cross them (e.g. to explore the exotic other side). The concepts explanatory scope has, thus, far responded to the normative claim that a borderless Europe encourages and increases mobility. However, in previous studies applying the concept of (un)familiarity, an explanatory problem remains concerning people's unarticulated and perhaps deeper reasons for mobility and lack thereof. This leaves a question mark as to why feelings of (un)familiarity occur in the first place as well as the actual degree to which they constitute barriers and provide incentives for mobility. The concern in this article is to deepen our understanding of the concept of (un)familiarity. It enriches the bandwidth of the unfamiliarity concept by relating it to a notion of socio-spatial identity-formation, which takes into consideration the psychological aspects involved when identities form. By doing so, the concepts explanatory scope is extended, making it possible to explain some of the complexity involved when feelings of (un)familiarity occur. It, thus, also answers the question why (un)familiarity cannot be translated into normative claims about cross border mobility.  相似文献

The ancient port city of Sumhuram (Dhofar Governorate, Sultanate of Oman) has been the focus of over 20 years of research by the Italian Mission to Oman (IMTO), University of Pisa, in collaboration with the Office of the Adviser to His Majesty the Sultan for Cultural Affairs (Muscat-Salalah, Sultanate of Oman). Excavation has revealed most of the town layout, leading to the identification of several buildings, alleyways, squares and workshops, among which two massive buildings stand out, significantly named by the excavators as “Monumental Building” 1 and 2 (MB1 and MB2). This paper presents the results of the excavation inside MB1, characterised by the presence of the only well discovered within the city walls, which was previously interpreted alternatively as a palace or as a temple. The architectural development of the building, its distinctive features, the archaeological material discovered inside it, and its chronology will be discussed. These results highlight the absence of fitting parallels from other ancient South Arabian towns. Overall, it is clear that access to, management of, and control over the water supply of the town represented a key asset which justified the huge investment in workforce and building materials that is reflected in the monumental architecture of this edifice.  相似文献

Under which conditions do politicians listen to scientific experts in a crisis? This study addresses this question by assessing how the Swiss government implemented 186 policy recommendations formulated by the National COVID-19 Science Task Force (STF) to combat the spread of the virus and alleviate its impact on the health system, society and economy during the first year of the pandemic. Results of multiple regression analyses show that the impact of problem pressure on the propensity of the government to implement experts' recommendations varies over time: it was considerably larger during spring 2020 than afterwards. We argue that this reflects a change in status of the STF during the second phase of the pandemic: it was distanced from the political-strategic level of the crisis management organization and its epistemic authority was increasingly questioned by political parties and interest groups. Policy scholars should thus give more attention to how rapidly the government's propensity to rely on expert advice can change.  相似文献
