Growing international migration constitutes a tremendous challenge for contemporary democracies, no more so than for minority nations. An important challenge for the latter is one of acceptance of immigration from the native‐born population, in a context in which immigrant can be seen as both a cultural and a political threat. In this article we ask what explains attitudes towards immigration in minority nations. More specifically, we seek to provide answers to these questions: What is the impact of cultural insecurity on attitudes towards immigration in minority nations? Is strong attachment to a minority nation associated with less positive attitudes towards immigration? And finally, are proponents of independence for minority nations more likely to favour a reduction in the level of immigration than those who oppose it? The article seeks to answer these questions by exploring the case of Quebec.  相似文献

One strategy used to increase response rates when using mail questionnaires is to prolong the period of data collection. This paper examines the consequences of such a strategy on the Australian Election Studies (1996–2004). The findings suggest that such a strategy has both positive and negative consequences on the overall quality of the survey. On the one hand, prolonging the period of data collection decreases the non-response error by providing a somewhat better representation of hard-to-reach groups of respondents such as the young, full-time employed, and those disinterested in politics. On the other hand, prolonging the period of data collection increases the risk of measurement error. The evidence suggests that post-election events significantly impact on respondents' political opinions. More specifically, the longer respondents wait to return their questionnaire after the elections the more positive their opinions of winning leaders, the more negative their opinions of defeated leaders and the more distant they feel with the policies of defeated parties. Australian investigators thus face a dilemma in deciding when to stop the fieldwork period for their mail election surveys: they must choose between non-response error and measurement error.  相似文献

ABSTRACT

Pastoralism and camelid management have been essential to all aspects of pre-Hispanic Andean societies. Here, we present zooarchaeological and isotopic data on domestic camelid remains from Huaca Cao Viejo (El Brujo archaeological complex) on the northern coast of Peru, and dated to the Lambayeque/Sicán period—to characterise their biological age, diet, life history, possible geographic origin and ritual use. Domestic camelids, representing a wide range of biological ages and a high rate of polydactyly, were found as burial offerings in direct association with human funerary bundles (fardos). Direct AMS dates indicated that camelids were buried over a short period of time (AD 1022–1176) confirming the Lambayeque presence in the Chicama Valley during the first half of the Late Intermediate Period. Stable isotopic analyses were carried out on both bone collagen and hair keratin, including incremental analysis. A considerable variability in δ13C values at both the intra-individual and the intra-group level and a large contribution of C4 resources to diet are shown. This clearly supports local management and camelids originating from various herds. Zooarchaeological and isotopic evidences suggest diversity in herding practices and suggest the importance of the herds in fulfilling the transportation demands for trade in goods.  相似文献
