This article reports key findings of a study which investigated the use of technology by 569 'digital natives' students for English Language learning and recreational purposes. Their views on the applicability of technological tools such as facebook, blogging and skype for English Language teaching and learning were also investigated. The findings showed that although the students expressed pos...

Colonization of new habitats through dispersal of phytoplankton cysts might be limited, if resident populations outcompete invaders during germination. We reciprocally transferred Gonyostomum semen (Raphidophyceae) cysts from three lakes into native and foreign waters originating from the respective habitats. Germination rate and germling growth were impacted by water origin, but there was no p...

Five specimens of the non-native three spot gourami (Osphronemidae: Trichogaster trichopterus) were collected from a small pond near the northern coast of Jamaica in June 2009. The collection represents the first documentation of this species in Jamaica. Origin of the introduction is not known. Herein, we discuss the occurrence of this species in Jamaica and possible threats posed to the island...

mtDNA haplotypes of representatives of the cosmopolitan peoples of north-central Mexico were studied. Two hundred twenty-three samples from individuals residing in vicinities of two localities in north-central Mexico were analyzed. A combination of strategies was employed to identify the origin of each haplotype, including length variation analysis of the COII and tRNALYS intergenic region, nuc...

BACKGROUND Chronic hepatitis B virus (HBV) infection affects up to 7% of the European population. Specific HBV genotypes are associated with rapid progression to end-stage liver disease and sub-optimal interferon treatment responses. Although the geographic distribution of HBV genotypes differs between regions, it has not been studied in Switzerland, which lies at the crossroads of Europe. ME...

the expansion of grey- black pottery tradition in the iranian plateau, on the basis of iron age theory of cultural dynamism, was emerged by the end of the 2nd millennium bc. such a pottery tradition is regarded as a cultural sign to point migrants who entered in the iranian plateau from the northern outside of caucasus the major. according to the theory, the migrants passed the river valley of ...

We describe a monolingual English corpus of original and (human) translated texts, with an accurate annotation of speaker properties, including the original language of the utterances and the speaker’s country of origin. We thus obtain three sub-corpora of texts reflecting native English, non-native English, and English translated from a variety of European languages. This dataset will facilita...

We analyzed in detail the wages of Latinos of Mexican origin, Central/South Americans, and Puerto Ricans. The wage structure facing second and thirdand higher-generation Latinos is very similar to the wage structure of thirdand higher-generation White workers. Unlike African American workers, more than half of the native Latino/White wage gap can be accounted for by the lower educational attain...

The replication initiator protein RepA of the IncB plasmid pMU720 was shown to induce localized unwinding of its cognate origin of replication in vitro. DnaA, the initiator protein of Escherichia coli, was unable to induce localized unwinding of this origin of replication on its own but enhanced the opening generated by RepA. The opened region lies immediately downstream of the last of the thre...
