Morphosyntactic transference of Aymara in Spanish por Romero Sihuayro, Miguel Angel

“…The result of the research show that the contact of languages which characterizes the C.P. Challapampa, gives rise to linguistic transference phenomena, especially at the morphosyntactic level where students make use of the morphosyntactic structure of Aymara S + O + V to write in Spanish, which is incorrect, since the structure of Spanish is S + V + O; frequent use of expressions such as hemosand taba; loan words from the Aymara language such as the expressions waka, awatiw; and finally the replacement of the vowel /e/ with /i/.…”

“…Data on individual chemicals (ie, benzene, toluene, xylenes [summation of ethylbenzene, m-xylene, p-xylene, and o-xylene]) and the aggregate mixture (ie, BTEX) were estimated using a chemistry-climate model.We examined the short-term associations of each individual chemical as well as the BTEX mixture with daily total, cardiovascular, and respiratory mortality in a multicountry framework.Using a two-stage time-series design, we first applied generalised additive models with a quasi-Poisson distribution to obtain location-specific associations, which were subsequently pooled using random-effects meta-analysis.Two-pollutant models were used to assess the independent effects of BTEX after adjusting for co-pollutants (PM 25 , PM 10 , nitrogen dioxide, sulphur dioxide, ozone, and carbon monoxide).Additionally, we assessed the overall exposure-response curves with spline terms.Findings An IQR increment of BTEX concentration on lag 0-2 days (3-day moving average of the present day and the previous 2 days) was associated with increases of 057% (95% CI 049-065), 042% (030-054), and 068% (050-086) in total, cardiovascular, and respiratory mortality, respectively.The corresponding effect estimates for an IQR increment in individual chemicals (benzene, toluene, and xylenes) were 038-061%, 044-070%, and 041-065%, respectively.The associations remained significant after adjusting for co-pollutants, with a general decline in magnitude, except for a slight increase after adjustment for ozone.The shape of the exposureresponse curves for all pollutants and causes of death was almost linear, with steeper slopes at low concentrations and no discernible thresholds.Interpretation This global study provides novel evidence linking short-term exposure to ambient BTEX, both individually and as a mixture, with increased daily total, cardiovascular, and respiratory mortality.Our findings underscore the need for comprehensive air pollution mitigation policies, including stringent controls on BTEX emissions, to protect public health.…”
