This study investigates the effects of climatic variations and extremes captured by variability in temperature, precipitation, and incidents of typhoons on aggregate inter-provincial migration within the Philippines using panel data. Our results indicate that a rise in temperature and to some extent increased typhoon activity increase outmigration, while precipitation does not have a consistent...

The main purpose of this paper is to study the roles of ethnicity and language acculturation in determining the propensities to make interprovincial migration in Canada in 1976-81, 1981-86, and 1996-2001, based on the micro data of the 1981, 1986 and 2001 censuses. Since these propensities are also subject to the strong effects of other explanatory factors, a multivariate analysis using a binom...

We present a number of variously rearranged matrix plots of the 3, 107×3, 107 1995-2000 (asymmetric) intercounty migration table for the United States, principally in its bistochasticized form (all 3,107 row and column sums iteratively proportionally fitted to equal 1). In one set of plots, the counties are seriated on the bases of the subdominant (left and right) eigenvectors of the bistochast...

In this issue of the Journal, Coldman et al. report results from the Pan-Canadian Study of Mammography Screening and Mortality from Breast Cancer, an analysis of observational data from seven of 12 provincial screening programs from 1990 to 2009 (1). They find that " participation in mammography screening programs in Canada was associated with substantially reduced breast cancer mortality, " wi...

Migration is one of the most important issues in Turkey today. Notably, the state forest enterprises are affected by the social, economic, and ecological dimensions of migration; these enterprises find it increasingly difficult to find labor to operate effectively in the forestry activities with each passing day. This study examined population movement over the 1965-2013 period in Kastamonu for...

The degree to which extrinsic factors influence migration chronology in North American waterfowl has not been quantified, particularly for dabbling ducks. Previous studies have examined waterfowl migration using various methods, however, quantitative approaches to define avian migration chronology over broad spatio-temporal scales are limited, and the implications for using different approaches...
