This essay examines the ways in which the social organization of migration interacts with domestic structures in the reception country. Taking the case of Greece, the current reception policy encourages temporary migrant settlement, while the socio-economic structures and cultural familiarity with the host society support individual integration in the society and the informal economy, but discourage migrant community representation. In addition, the political environment has supported Kurdish diaspora politics that, in turn, enhanced existing fragmentation within the ethnic group. The aim of this essay is to highlight the dimensions affecting temporary and permanent migrant settlement in Greece through empirical findings. 相似文献

In the article, the entrance probabilities and the probability distribution of the number of transitions to a state are studied to provide some answers to questions related to state occupancies for the semi Markov model. Biological sequences and Web navigation are two cases that initially seem to be different but to a certain extent they do have similarities. Two main aspects of word occurrences in biological sequences are: (a) where do they occur and (b) how many times do they occur. In Web navigation the similar questions are (a) when a node is visited and (b) how many times a node is visited. So, the theoretical results of this study are applied to model these two cases and derive distributions of word location or node occurrence and frequency of occurrences. Rewards/costs are included in the Web navigation model and analytic forms for the means, variances, and moments of total interval rewards/costs are provided. 相似文献

In the present article we study the asymptotic behaviour of the sequence of vectors with components expectations, variances, and covariances of the state sizes of a semi-Markov system. In this respect, we transform the semi-Markov system into a Markov system with a different though equivalent state space and relate the sequence of the transition probabilities of the respective Markov system as functions of the parameters of the semi-Markov system. Also, we study the asymptotic behavior of the sequence of vectors with components variances and covariances of the duration state sizes, of the related Markov system, under perturbation of the transition probability matrices. We use the results in the study of asymptotic behavior under perturbation of the sequence of vectors with components variances and covariances of the semi-Markov system. 相似文献
