Compositional Analysis of Ceramics from Goguryeo Fortified Sites in Central Korea

The aim of this paper is to investigate whether the ceramics from the Goguryeo fortified sites of the Han River region in central Korea were manufactured and consumed locally during the southern expansion of the Goguryeo State (475–551 ce ). For this research, 88 ceramic samples from seven contemporary sites in the southern territories of Goguryeo were sampled and analysed by ceramic thin‐section petrography and neutron activation analysis (NAA). In addition, to establish a possible chemical fingerprint at Hongryeonbong Fort 2, five clay specimens were also gathered and analysed from the pottery firing structure. The results of this analytical study indicate that the majority of the ceramics from the Goguryeo fortified sites of central Korea were produced and circulated within this newly acquired region. In addition, it is highly probable that Hongryeonbong Fort, which contains the remains of what may be ceramic firing architecture, is the place of production for the ceramics.     

Learning by ‘design’: how undergraduates in Singapore learn to become engineers

ABSTRACT

In this paper, we explore the evolving norms and dispositions of creativity and enterprise of engineering students using data gathered from a newly established technology and engineering-focused university called ‘UniTech’ located in Singapore. Based on interviews with students, we seek to explain (1) what they learn, reject, adopt and appropriate; (2) the kinds of challenges they face and (3) the unexpected and serendipitous outcomes of their learning. Through an integrated engineering curriculum focusing on design, students learn to be technically competent, creative and entrepreneurial persons. This paper considers how the curriculum works as a set of formal procedures preparing students for a future ‘knowledge-based economy’ imagined to be technology-intensive, dynamic and filled with opportunities but also increasingly uncertain. We analyse how students at UniTech negotiate this design-focused curriculum where experiences of creativity, open-ended possibilities and holistic perspectives intersect with the national economic agenda of a knowledge-based economy.     

Integrating Transportation Network and Regional Economic Models to Estimate the Costs of a Large Urban Earthquake

In this paper we summarize an integrated, operational model of losses due to earthquake impacts on transportation and industrial capacity, and how these losses affect the metropolitan economy. The procedure advances the information provided by transportation and activity system analysis techniques in ways that help capture the most important ecomonic implications of earthquakes. Network costs and origin-destination requirements are modeled endogenously and consistently. Indirect and induced losses associated with direct impacts on transportation and industrial capacity are distributed across zones and ecomonic sectors. Preliminary results are summarized for a magnitude 7.1 earthquake on the Elysian Park blind thrust fault in Los Angeles.     

Provincializing Albert Schweitzer's Ethical Colonialism in Africa

Unlike many commentators who tend to see Schweitzer's mission one-sidedly, I show the coexistence of liberal and conservative elements in his mission. While his mission intent was mostly motivated by the former, his mission practices largely show the latter. In this essay, I analyze them in detail in three parts. I first explain how such opposite elements can coexist by applying Dipesh Chakrabarty's notion of provincializing Europe. Like most nineteenth-century Western liberals, Schweitzer advocated Enlightenment rights for Europeans, but denied them to the colonized. I then argue that Schweitzer's mission was motivated by the liberal elements of his theology. When his critical theology led him to deny the divinity of Jesus, he found a new basis for Christianity in Jesus’ ethical activism, which led him to become a medical missionary to Africa. I then examine Schweitzer's conservative practices in Africa: by applying the developmental model of Hegelian-Marxist historicism to African society, Schweitzer opposed both decolonization and advanced learning to Africans. Schweitzer's missionary practices in Africa, I therefore conclude, were more conservative than those of the typical European missionary.     

马韩古坟坟丘的区划盛土法

坟丘的区划盛土法是指在筑造坟丘时将其分成许多区域,由不同人力分别承担作业的筑造方式。为识别区划界限可设置异色粘土带、土囊列或排列石材作为标志物。坟丘的区划方向都是从坟丘中心呈放射状分布的,随着坟丘规模的扩大,区划数也在增多。中国春秋时期已使用区划盛土法这种技术,因而这种盛土方法应当是起源于中国。     

The persistence of white ethnicity in New England politics

There was a consensus among earlier students of New England politics that the political influence of European ancestry was fading by the latter half of the 20th century. We examine this proposition in recent times by exploring the role of ethnic ancestry in explaining the political divide in the region's presidential voting in over 1500 New England towns. Contrary to earlier predictions, ethnic origin does retain some explanatory power in models of recent voting behavior, and ethnic cleavages have not been entirely replaced by economic divisions in the electorate. Although the settlement patterns of the more established and numerous nationality groups (i.e. Irish and Italians) are less associated with partisanship than they were 50 years ago, the political salience of white ethnicity persists, suggesting that ethnic groups do not simply dealign or politically “assimilate” over time. Some groups maintain a strong identity in spite of upward mobility because movement from city to suburbs is selected not just on housing, income or school characteristics, as is usually the case, but on ethnicity too. Towns with significant concentrations of specific European ancestry groups lean Republican, even after we have accounted for the presence of other sources of political leaning and past voting tendencies, while Democratic attachments are undeniably strong in towns where the newer immigrant groups have settled. The “new ethnicity” (i.e. racial minorities) and the “old ethnicity” (i.e. white ethnics) clearly carry distinct political implications for this region's presidential politics.     

Development of Damage Patterns and Fragility Curves in Brick-nogging Buildings from the Thabeikkyin Earthquake,Myanmar, 2012

The Thabeikkyin earthquake (moment magnitude scale of 6.8) occurred on November 11, 2012; its epicenter was located 25 km from Thabeikkyin Township, Mandalay Region, Myanmar. Many buildings were damaged severely during the earthquake. In this study, damage patterns of brick-nogging buildings were firstly developed, and damage grades were characterized to allow for easy classification of the damaged buildings. The damaged data of all building types in the surveyed areas were collected by classifying the four damage levels as no damage, slight damage, moderate damage, and heavy damage. To develop the damage patterns of brick-nogging buildings, damage categories were arranged into three damage grades (slight, moderate, and heavy damage). Secondly, a questionnaire survey was conducted to calculate the seismic intensities of the affected areas. Medvedev–Sponheuer–Karnik (MSK) seismic intensities for the surveyed areas were estimated by analyzing the questionnaire survey responses. Finally, fragility curves for brick-nogging buildings were constructed using the estimated seismic intensities from the survey responses combined with the damage levels. These fragility curves may be useful to assess damage to brick-nogging buildings and to predict the number of damaged buildings in future earthquakes.
