We examine Canada's recent Syrian Refugee Resettlement Initiative (SRRI) paying close attention to the resettlement role played by mid‐sized urban communities. We elaborate on a key policy dimension at work at this scale of action: local immigration partnerships (LIPs). We start with a very brief review of Canada's history of mass refugee resettlement. Second, we assess the policy of LIPs, particularly how they have been presented as a form of “place‐based policy,” and third, we offer an overview of the role the LIPs played in three case study communities (Hamilton, Ottawa, and Waterloo) during the SRRI. Finally, we present three overarching themes that emerged from our research in each of these communities: the importance of each community's history of immigration and refugee resettlement; the embeddedness of the LIP and its leadership in the local community; and how the positioning of each LIP relative to the three levels of government and its official Resettlement Assistance Program agreement holders impacted its ability to act. The history, location, and place characteristics of each community influenced the nature of intersectoral and intergovernmental relations in distinctive ways, and differentially shaped the effectiveness of each LIP's ability to contribute to the SRRI. 相似文献

Bone collagen is found throughout most of the archaeological record. Under experimental conditions, collagen is apparently
preserved as an intact molecule, with amino acid compositions and isotopic profiles only changing when almost all of the protein
is lost. The ubiquity of collagen in archaeological bone has lead to the development of the use of collagen peptide mass fingerprints
for the identification of bone fragments—Zooarchaeology by Mass Spectrometry (ZooMS). We report a novel, but a simple method
for the partial extraction of collagen for ZooMS that uses ammonium bicarbonate buffer but avoids demineralisation. We compared
conventional acid demineralisation with ammonium bicarbonate buffer extraction to test ZooMS in a range of modern and archaeological
bone samples. The sensitivity of the current generation of mass spectrometers is high enough for the non-destructive buffer
method to extract sufficient collagen for ZooMS. We envisage that a particular advantage of this method is that it leaves
worked bone artefacts effectively undamaged post-treatment, suitable for subsequent analysis or museum storage or display.
Furthermore, it may have potential as a screening tool to aid curators in the selection of material for more advanced molecular
analysis—such as DNA sequencing. 相似文献

In this work the analytical results obtained by ICP-MS with laser ablation solid sampling and SEM-EDS for some polychrome glass vessels from the Iron Age are presented and discussed. The samples, coming from Etruscan sites near Adria (Northern Italy), belong to the so-called Mediterranean Groups I, II and III and are dated from the 5th, 3rd and 2nd century B.C., respectively. To date, analytical data for only two sets of vessels of the Iron Age have been discussed in the literature. In spite of the low number of available samples, this is the first time that vessels of all three periods are analytically compared. Elemental concentration data show that the samples can be classified as low-magnesia-low potash (LMLK) soda-lime-silica glasses, with low phosphorus and titanium contents, in agreement with data for similar samples of the same age. Bivariate and multivariate analyses of the contents of many elements characterizing the siliceous sands showed three distinct sets corresponding to the three periods. Since the sets indicate different provenances of the sands it seems rational to assume that different glassmaking locations were involved. Chromophores and opacifiers of the blue bodies and the yellow, white and turquoise decorations of the vessels were analytically identified, while the nature of the corresponding ores was hypothesized. 相似文献

ABSTRACT Border cities or regions are in theory more affected by the EU integration process than more central locations as it more drastically influences their transaction costs and market potential. We find a positive empirical effect of EU enlargement as measured by the growth in population share along the integration borders. This effect is active for a limited distance (70 km) and time period (30 years), and is more important for large cities and regions. Despite this positive EU enlargement effect along the border, a location close to a border remains a burden in view of the (larger) negative general border effect. 相似文献

ABSTRACT An important subset of the literature on agglomeration externalities hypothesizes that intrasectoral and intersectoral relations are endogenously determined in models of local and regional economic growth. Remarkably, structural adjustment models describing the spatio‐temporal dynamics of population and employment levels or growth traditionally do not include intersectoral economic dynamics. This paper argues and shows that allowing for economic linkages across sectors in these models adds considerable value, especially in forecasting. An econometric model of population–employment dynamics, in which sectoral variations in economic development are explicitly taken into account, is applied to a large urban planning policy proposal in the Netherlands. The empirical analyses suggest that population dynamics are largely exogenous, population changes drive employment in particular in the industry and retail sectors, and employment in all sectors depends strongly on intersectoral dynamics. Intersectoral dynamics appear as important drivers of regional sectoral employment changes; they are even more important than population changes, and their effect shows up clearly even within the Dutch institutional context where strict regulatory housing and planning restrictions are enforced. 相似文献
