OBJECTIVES The objectives of this study were to investigate differences on health protection status between two generations (born pre- vs. post- 1980) of rural-to-urban migrants in China, and whether the differences are associated with spatial contexts. METHODS Respondent-Driven Sampling (RDS) approach was used to recruit migrants in Chengdu city from September 2008 to July 2009. All migrants...
BACKGROUND It has been frequently reported a higher incidence of psychotic disorders in immigrants than in native populations. There is, however, a lack of knowledge about risk factors which may explain this phenomenon. A better understanding of the causes of psychosis among first-generation migrants is highly needed, particularly in Italy, a country with a recent massive migration. METHODS/D...
The Larva monitoring tool has been successfully applied to a number of industrial Java systems, providing extra assurance of behaviour correctness. Given the increased interest in concurrent programming, we propose Elarva, an adaptation of Larva for monitoring programs written in Erlang, an established industry-strength concurrent language. Object-oriented Larva constructs have been translated ...
I N addition to the principal imaginal discs (cephalic, labial, wing, haltere, leg and genital), the larva in Cyclorrhapha carries as discrete components the rudiments of the imaginal segmental abdominal hypodermis, salivary glands, fore-, midand hind-gut, lateral cerebral ganglia and segmental tracheal system (Snodgrass, 1924; Bodenstein, 1950; Shatoury, 19566; Anderson, 1964, etc.). The embry...
The ultimate stadium larva of Neuraeschna claviforcipata is described and illustrated based on an F-0 exuvia of a reared female from northern Amazonas State, Brazil. This larva differs from the other two known larvae of the genus in lacking the spiny lateral prominence of the mandible, and in having only a short spine each side of the median cleft of the prementum; labium is shorter and cercus ...
Figure 1. The giant tubeworm Riftia pachyptila. (A) Dense aggregation at a hydrothermal vent of the East Pacific Rise. (B) Life cycle with aposymbiotic phase from fertilized egg to settled larva (blue), and symbiotic phase from larva in metamorphosis to adult (red). Infection of Endoriftia (red) from a free-living microbial community occurs in the larva. (C) Relationships of siboglinids outlini...
Previous research suggests that Mexican female migrants face more barriers than their male counterparts. However, few studies examine how the educational characteristics of female migrants differ from those of male migrants and how selectivity may have changed in the context of evolving gender dynamics in both countries. This study uses U.S. and Mexican census data from 1960 to 2000 to compare ...
We examined migration in China using the 2005 inter-census population survey, in which migrants were registered at both their place of original (hukou) residence and at their destination. We find evidence that the estimated number of internal migrants in China is extremely sensitive to the enumeration method. We estimate that the traditional destination-based survey method fails to account for ...
This study focuses on Wenzhou migrants and explains the developmental path of overseas migrants’ sustained entrepreneurship. It also analyzes how migrant entrepreneurs fit into the Italian culture to improve ambidextrous innovation ability. This paper applies the methods of induction and longitudinal study, conducts case studies on four migrant entrepreneurs, and explores embedding strategies i...
An anisakid nematode larva found in cod sold in the state of Minas Gerais, Brazil was studied by light and scanning electron microscopy and by a molecular approach. Mitochondrial cytochrome c-oxidase subunit 2 (mtDNA cox-2), 28S rRNA and ITS1, 5.8S and ITS2 regions were amplified using the polymerase chain reaction and sequenced to evaluate the phylogenetic relationships of the larva. The genet...
