A) COMPARISON OF TWO PAIR
ARTICLES (SCIENTIFIC AND POPULAR)
1. Comparison
between articles “A” & “B”.
The popular article (“B”) does not address everything what was
wrote on the scientific one (“A”), because the scientific article talks about
very specific research information on how rural out-migration in Mexico had
affected the deforestation levels, agricultural intensification, and deforestation
in the Neotropics (such as Mexico), it also gives a message (which I totally
agree) that with social and government support, proper human development
strategies involving the active participation or rural people Mexico’s society
can face and reduce the deforestation levels. On the other side, the popular
article pointed out what are the main factors of deforestation worldwide.
However, both articles have something very important in common: Deforestation
expansion as a negative cause of deforestation in many countries (Mexico as one
them), mainly because of non-sustainable agriculture practices, and extensive
use of grasslands for livestock.
2. Comparison
between articles “C” & “D”.
The popular article (“D”) address very accurately the science
article (“C”) about the oil spill happened in April, 2010 in the Gulf of
Mexico. The popular article summarized and clearly explained the data on the
scientific article: This was a tremendous oil spill (notice that nearly 5
million barrels (210 million gallons) of oil spewed), “the oil spill and plume
covered nearly 360 square miles, about the size of Dallas, Texas”- according to
the research article. The task that the first researches had was to investigate
what were the results/impact that this event caused on the deep-sea ecosystem
and the natural resources around the area. Even though part of “the oil was
removed by cleanup operations and other natural mechanisms it is estimated that
35% of hydrocarbons from the oil were trapped” in the surface and deep sea and devastating
the biodiversity of the Gulf of Mexico. Sadly, the recovery rates in the deep sea are likely to be
slow, on the order of decades or longer.

SCIENCE ARTICLE ANALYSIS (ARTICLE “A”)
What this a controlled experiment? Yes.
What was the control?
Tables and graphs that provided analysis of deforestation
rates in relationship to percentage of population.
What were the hypotheses of the experiment?
What were the hypotheses of the experiment?
One of the theories the article showed was that the agriculture’s
out-migration from Mexico caused the abandonment of agricultural production
which in turn, became one of the main causes of recovery of forested areas.
Did the data support the hypothesis (hypotheses)?
NO, according to the research that the authors did, people
migrating to the U.S. is a response to rural and urban unemployment, and once
they save enough money they invest in livestock and sell their grasslands to
bigger farmers that keep expanding agriculture (without applying
sustainability). As mentioned on this article: “Expansion of agriculture is the
largest driver of deforestation in underdeveloped tropical countries”, such as
Mexico.
Were the methods repeatable?
Yes, the data provided by the tables on the article were
obtained from 10 to 15 case studies (some of them went from 1986 to 2000)
analyzed by Galvan and colleagues (2009).
Was there adequate replication?
Was there adequate replication?
Yes, on page 869 was showed a brief description of two cases
derived from their own field research, in which neoliberal policies propelled
significant land-use change by inducing international migration and
discouraging or outcompeting small-farmer maize production.
Was there a founding source to that may be
a conflict of interest?
This research project was funded by the Consejo Nacional de Ciencia y Tecnologia (projects 51253 and 45636) and by the University of California Institute for Mexico and the United States program (2008-2009).
