1. Valoración de la idoneidad epistémica y cognitiva de un proceso de instrucción en la resolución de problemas bayesianos
This paper aims to present the assessment of an instructional process about the Bayes Theorem carried out with 50 Engineering students in a Statistics class of the Universidad Nacional de Mar del Plata. Under the theoretical and methodological framework of the Ontosemiotic Approach to Mathematical Cognition and Instruction, this assessment is done in epistem

2. Evaluación de sesgos en el razonamiento sobre probabilidad condicional en futuros profesores de educación secundaria
In this paper we present a study aimed at assessing biases in conditional probability reasoning in prospective secondary school and high school mathematics teachers. We analyze responses to 7 items taken from the CPR (conditional probability reasoning) in a sample of 196 last year mathematics students and Máster students, finding a high incidence in both gr

3. Raciocínio condicional : O uso de modelos mentais influenciados pelo acesso da informação na memória
This study investigates conditional reasoning within the mental model framework and the influences of semantic memory. Conclusions in conditional reasoning are explained in terms of mental models for the If P then Q rule, according to Johnson-Laird (2001). However, mental model theory has explored very little on the elaboration of additional models which cou

4. Desenvolvimento farmacotÃcnico e desenvolvimento de estabilidade de comprimidos à base de captopril / Pharmacotechnician development and a study based on the stability of tablets with captopril
Hypertension is a public health problem considered by the Worldwide Health Organisation (OMS) as the third death cause in the world, overpassing only by unsafe sex and malnutrition. In the world, there are 600 million hypertensive people. In which of these, 500 million need an immediate medical intervention. In Brazil, there are about 30 million infected by

5. Cross-cultural evidence of cognitive adaptations for social exchange among the Shiwiar of Ecuadorian Amazonia
On the basis of evolutionary game theory, it was hypothesized that humans have an evolved cognitive specialization for reasoning about social exchange, including a subroutine for detecting cheaters. This hypothesis led to a specific prediction: Although humans are known to be poor at detecting potential violations of conditional rules in general, they should

6. Years of Life Lost due to exposure: Causal concepts and empirical shortcomings
Excess Years of Life Lost due to exposure is an important measure of health impact complementary to rate or risk statistics. I show that the total excess Years of Life Lost due to exposure can be estimated unbiasedly by calculating the corresponding excess Years of Potential Life Lost given conditions that describe study validity (like exchangeability of exp

7. Conditional switching of vascular endothelial growth factor (VEGF) expression in tumors: Induction of endothelial cell shedding and regression of hemangioblastoma-like vessels by VEGF withdrawal
We have recently shown that VEGF functions as a survival factor for newly formed vessels during developmental neovascularization, but is not required for maintenance of mature vessels. Reasoning that expanding tumors contain a significant fraction of newly formed and remodeling vessels, we examined whether abrupt withdrawal of VEGF will result in regression

8. Suppression of signal sequence defects and azide resistance in Escherichia coli commonly result from the same mutations in secA.
The SecA protein of Escherichia coli is required for protein translocation from the cytoplasm. The complexity of SecA function is reflected by missense mutations in the secA gene that confer several different phenotypes: (i) conditional-lethal alleles cause a generalized block in protein secretion, resulting in the cytoplasmic accumulation of the precursor f
