建国初期知识分子思想改造运动研究述评

建国初期,中国共产党为确立马克思主义在意识形态领域的指导地位,提出从旧时代过来的各个阶级阶层的人都要通过政治学习和思想改造以适应新时代的要求,而且将知识分子的思想改造放在首位,认为这是我国在各方面彻底实现民主改革和逐步实行工业化的重要条件之一。1951年秋至1952年秋,知识分子思想改造运动迅速从北京、天津20余所高校推广到     

THE ACTUAL AND PERCEIVED EFFECTS OF FLOODPLAIN LAND-USE REGULATIONS ON RESIDENTIAL PROPERTY VALUES IN LONDON, ONTARIO

The impacts associated with floodplain management adjustments should be understood. This paper addresses this need by describing the perceived and actual impacts floodplain regulations have had on residential land values in a portion of London, Ontario. The institutional arrangements for floodplain regulation and the actual practice of regulation in the City of London for the period 1978–1989 are described. Actual impacts on land values were determined through use of a geographical matching technique based on data obtained from mls sources and permit data available at the Upper Thames River Conservation Authority office. Perceptual data were acquired from a questionnaire survey of floodplain landowners. Findings indicate that most residents perceived that no impact on land values was associated with floodplain regulations. This view was supported by the analysis of actual home transactions     

Stable isotopes as indicators of change in the food procurement and food preference of Viking Age and Early Christian populations on Gotland (Sweden)

Archaeological samples of human and faunal remains dating from the Viking (9–11th century AD) and Early Christian (11–12th century AD) periods of Gotland, Sweden were assayed through stable carbon and nitrogen isotope analysis in order to investigate whether changes in subsistence occurred between these periods, particularly regarding the importance of seafood. The study was concerned with how the dietary regime of the Baltic trading port and farming settlement at Ridanäs, Gotland was affected by the widespread environmental and sociocultural transformations that characterized the end of the Viking Age. More generally, the research considers how changes in both food procurement and preference may account for observed differences in the dietary regimes of individuals from the Viking Age and the Early Christian period.     

A multi-proxy palaeoenvironmental investigation of the findspot of an Iron Age bog body from Oldcroghan,Co. Offaly,Ireland

In 2003, the remains of an Early Iron Age bog body, known as ‘Oldcroghan Man’, were recovered during the cutting of a drainage ditch in a bog in the Irish Midlands. Only some fingernails and a withe fragment remained undisturbed in situ in the drain face, providing the sole evidence for the original position of the body. A detailed reconstruction of the depositional context of the body has been undertaken through multi-proxy analyses of a peat monolith collected at the findspot. The palynological record shows that the surrounding area was the focus of intensive human activity during the Later Bronze Age, but was largely abandoned during the Bronze Age–Iron transition in the mid-first millennium BC. In the mid-4th century BC, a bog pool developed at the site, evidenced in the stratigraphic, plant macrofossil, testate amoebae and coleopteran records. Plant macrofossil and pollen analysis of peat samples associated with the fingernails suggests that the body was deposited in this pool most likely during the 3rd century BC. The absence of carrion beetle fauna points to complete submergence of the body within the pool. Deposition occurred shortly before or around the time that the surrounding area again became the focus of woodland clearance, as seen in the extended pollen record from the peat monolith. This period corresponds to the Early Iron Age in Ireland, during which renewed cultural connections with Britain and continental Europe can be seen in the archaeological record and widespread forest clearance is recorded in pollen records from across Ireland. The palaeoenvironmental results indicate, therefore, that the demise of Oldcroghan Man took place at a pivotal time of socio-economic and perhaps political change.     

Inheritance relationship between Zhanggongxiang kiln celadon and Ru Guan celadon: Comments on the rationality of Raman Ip value evaluating firing temperature

The development of Chinese ceramics culminated during the Song dynasty. At this time, exquisite celadon works emerged, such as Ru Guan celadon and Southern Song dynasty official kiln celadon, which exhibited the glory of their era. Since the excavation of Zhanggongxiang kiln celadon in Ruzhou city, Henan province, China, it has been attracting widespread scholarly attention at home and abroad. Most scholars have suggested that Zhanggongxiang is the official kiln of the Northern Song dynasty. In this paper, taking the celadon unearthed from the Zhanggongxiang kiln as a sample, the combination of laser Raman spectrum and thermal expansion methods is used to study the inheritance relationship between Zhanggongxiang celadon and Ru Guan celadon in the firing process. Meanwhile, the rationality of using Raman I_p value to evaluate the firing temperature of ceramics is reviewed. The main conclusions are as follows. First, the firing temperature of Zhanggongxiang celadon with various glaze colours is quite different, whereas the firing temperature of the same glaze colour is similar, thereby inheriting the firing technology of Ru Guan porcelain. Second, the I_p value of glaze cannot evaluate the firing temperature of porcelain with similar firing temperature. The I_p value corresponds to a range, within which it does not fully conform to the rule that the larger the I_p value, the higher the firing temperature. The I_p value is also associated with the formulation in addition to firing temperature. It is applicable to evaluating porcelains with a similar formulation but a large temperature difference.     

Engaging students and maintaining quality in the era of massification: strategies and approaches for teaching large first-year courses

This article examines the nature of first-year international relations (IR) teaching in Australia. Cost pressures in the university sector have been met by economies of scale with foundational classes becoming very large, often with hundreds of students. The article critically reflects on current strategies for teaching these courses to meet the challenge of providing an engaging and high quality learning environment in large classes with widely fluctuating student entry scores, university preparedness, and educational capital and language competence. The article argues that a successful approach to improving the quality of first-year IR teaching and to accommodating the diverse learning needs of all students is to run these courses in multiple streams, with one dedicated to providing a richer, more active IR learning experience. In the era of ‘massification’, allowing students a level of guided autonomy in aligning their learning preferences with teaching methods is likely to increase engagement and motivation, thereby improving retention and degree progression.
