“Middling” Chinese Returnees or Immigrants from Canada? The Ambiguity of Return Migration and Claims to Modernity

This paper investigates the conceptual overlaps between transnational return migration and immigration by drawing on a qualitative study of Mainland Chinese return migration from Canada. The paper argues that reframing return migration as a distinct type of immigration draws attention to the citizenship vulnerabilities experienced by “middling” returnees who are not privy to the preferential treatment given to highly skilled returnees. They come to be considered as “foreigners” in their homeland because they have naturalised elsewhere. The paper also explores the double diasporic identifications of Mainland Chinese returnees from Canada; it highlights the tensions and fissures manifested in secondary diasporas, particularly in light of China’s growing prominence in international business, foreign diplomacy and cultural exchanges. The paper suggests that social encounters that marginalise such migrants in Canada are reproduced in China. The returnees navigate such encounters by mobilising their transnational affiliations to different national contexts.     

The Effect of Accelerated Alteration on the Discrimination between Baltic and Romanian Amber

Ten geological samples (five from each source—Romanian amber and Baltic amber) in duplicate for five different media (air, water, saline, acid and basic) were subjected to thermal alteration at 80 ± 2°C for 12 weeks, in the dark. The samples were analysed before and after the accelerated alteration experiment by Fourier transform infrared spectroscopy, both in transmittance and reflectance mode, and the acquired spectra were statistically processed by multivariate data analysis, mainly using principal component analysis. The results of the experiment are useful in giving a better picture of how to discriminate between archaeological amber artefacts.     

PROVENANCE DETERMINATION OF MYCENAEAN IIIC VESSELS FROM THE 1934–1939 EXCAVATIONS AT TARSUS‐GÖZLÜKULE BY NEUTRON ACTIVATION ANALYSIS

Neutron Activation Analysis (NAA) has been carried out in order to determine the provenance of a selected set of 30 sherds of Mycenaean style excavated at Tarsus‐Gözlükule. The provenance could be established or made feasible in 80% of the samples. The results confirm the current status of research, namely that in the LH IIIC phase trade patterns changed and Mycenaean wares, which used to be exported to the Near East, were now produced locally. At Tarsus, the LH IIIC imports came from Cyprus and the eastern Aegean.     

Atmospheric deterioration of Qin brick in an environmental chamber at Emperor Qin's Terracotta Museum, China

Potential mechanisms for the changing appearance of Qin terracotta was evaluated on simulated bricks with, SO₂, NH₃, O₃, and a NH₃/O₃ mixture for total dosages of 2.2–5.4 ppm-years. Changes in the surface composition and appearance were evaluated with scanning electron microscopy/energy dispersive X-ray analysis (SEM–EDX) and X-ray photoelectron spectroscopy (XPS). No observable changes with O₃ exposure were found. Sulfate as sulfur and ammonium as nitrogen increased by 1.2 at% and 0.8 at% of the surface deposit as determined by XPS. O₃ did not have a detectable effect by itself, but when combined with NH₃, NO₃ as nitrogen increased by 1.5 at%, indicating a strong oxidation of NH₃ to nitric acid. The combination of outdoor O₃ infiltration with indoor NH₃, presumably from the visitors, appears to have a greater potential for damage than either pollutant by itself. SEM–EDX mapping of the surface showed sulfur associated with calcium and magnesium compounds after SO₂ exposure, but not before. More detailed microscopic examination showed this primarily in the form of gypsum, especially near cracks and pits in the surface. Both of these mechanisms are probably among the causes of changes in terracotta appearances since they were unearthed in 1974.     

Environmental Quality and User Satisfaction in Mass Housing Areas: The Case of Istanbul

In a residence environment, housing and housing groups constitute a fundamental life space to meet the needs of the residents, to satisfy them, and to maintain the overall health of individuals and public. Various needs that appear due to the problems caused by housing and residence environment situated in a physical, psychological and socio-cultural environment together with their surroundings affect resident satisfaction and attitude, while directing the overall individual/family and public health, happiness and welfare. Most researchers argue about and try to determine the residents' needs related to their expectations of and satisfaction in housing and residence environment, within the framework of basic needs of human beings. In this study, in order to assess the factors that improve housing and environmental quality satisfaction, the concepts of housing and its environment, and the subject of housing and environmental quality satisfaction have been investigated; the conceptual model of housing and environmental quality satisfaction has been developed, which takes up the subject of user satisfaction in housing and environment quality as a whole; and the factors to increase the level of satisfaction in housing and environmental quality have been specified. A sum of 400 questionnaire inquiries has been made in planned mass housing areas in the Istanbul Metropolitan Area. Applying factor analysis to the data that have been gathered as a result of questionnaire inquiries, the following factors have been determined according to their order of importance to increase the level of user satisfaction in housing and environmental quality. The findings of this study show that, the elements influencing these factor groups include accessibility to various function areas in the inhabited housing area, environmental features of the housing, satisfaction in the various facilities in the inhabited environment, environmental security, neighbour relationships, and the appearance of the housing environment. A logistic regression model has been made to assess whether there are any differences among the factors influencing housing and environmental quality satisfaction for mass housing users on location choice (central districts and peripheral districts) at the metropolitan level.     

A Model for Measuring the Sustainability Level of Historic Urban Quarters

The main aim of this paper is to propose a model for measuring the sustainability level of historic urban quarters and to indicate an appropriate strategy for their revitalization. Based on this aim, this study first presents the theoretical review on the concept of “revitalization”, and its relationship with sustainability; next, it introduces the characteristics, role, selection process and scaling method of sustainability indicators, which are essential for measuring the level of sustainability. The paper then, as the main contribution of this paper, proposes the model for measuring the level of sustainability in historic urban quarters and determines some proposals to achieve revitalized and sustainable historic urban quarters. Depending on the proposed model, there is a direct relationship between type and the level of obsolescence (revitalization) and the level of sustainability in the physical, economic and social structures of a particular area. Therefore, when the level of sustainability is high in any one of these three structures, it means that the level of obsolescence is low in the same structures of an historic urban quarter. The result of this paper leads us to say that, the level of sustainability is a new (additional) input in the strategic planning process of revitalization and sustainable urban revitalization of historic urban quarters. Finally, the paper concludes with a brief summary on the general arguments of the paper.
