The model describes the system by aggregated variables that represent the fraction of speakers of each language, where a higher local density of speakers and a higher prestige, the relative status of a language, tend to increase the density of speakers of a language.
(Flege, Yeni-Komshian and Liu 1999; Bialystok, 1997)[22] The fact that many adults and older children can learn both first and second languages to a high degree of proficiency makes clear that unlike the kitten visual system studied by Hubel and Wiesel, the language acquisition system in humans is not subject to a critical period in the strict sense.
A number of researchers also claim that appropriate use of formulaic sequences can help language learners reach a higher level of language proficiency not only in terms of fluency, but also in terms of range of expression and accuracy (e.g., Wood, 2006; Boers et al., 2006; Wood, 2010; Stengers et al., 2010; Stengers et al., 2011; Boers & Lindstromberg, 2012; Henriksen, 2013; Peters, 2014).
We also observed a surprising lack of genetic substructure in Botswana, despite multiple tribal ethnicities and language groups, alongside a higher degree of relatedness than purported founder populations from the 1000 Genomes project.
Potential migrants tend to choose countries that share a similar language and have a higher share of migrants from their home country.
The findings of the current study are also in line with the findings obtained in the study conducted by Qi and Ding (2011) who found that more proficient language learners possess a higher inventory of formulaic sequence knowledge.
The shared mathematical language allowed both a higher level of collaboration with more established and successful fields and the achievement of results which were measurable and provable; AI had become a more rigorous "scientific" discipline.
While themes a, b, c and d were 'in vivo' codes suggested by respondents' own language, theme e, practice organisation, was of a higher analytical abstraction, constructed from respondents' descriptions of the way their practices were organised.
Other factors also keep the numbers down, including poverty, language barriers, a high incidence of obesity and diabetes among Hispanics, and a high dropout rate.
To be able to solve a crossword puzzle in a second language shows a high degree of skill and knowledge therein.
