Amigo, Hugo;
Cadernos de Saúde Pública , 2003, DOI: 10.1590/S0102-311X2003000700017
Abstract: obesity has emerged as an alarming public health problem, having increased rapidly in both adults and children. considering 12 countries with reported levels of overweight and obesity, one third have a 20% prevalence of one or both conditions. in 17 countries reporting data on obesity, the mean rate was 4.6%; four countries reported rates over 6%, while three reported less than 2%. the majority of these countries showed increases of 70% in overweight and 60% in obesity during the last decade. only two countries reported decreasing prevalence rates. countries may be classified in four groups: (1) low or even downward prevalence of overweight and obesity; (2) underweight reported simultaneously with an increase in obesity; (3) a large territory and population with differences in the prevalence of overweight and obesity between regions and socioeconomic groups; and (4) little underweight and high prevalence of obesity. in conclusion, there is no doubt about the increasing trend in overweight and obesity among latin american children. however, since there is no consensus as to diagnostic criteria for overweight and obesity, the real prevalence is not known.

Cadernos de Saúde Pública , 2003,
Abstract: En la actualidad, la obesidad constituye un problema de Salud Pública y ha aumentado en adultos y ni os. De 12 países latinoamericanos que tenían información completa de sobrepeso y obesidad algo más de un tercio supera el 20% en ambas situaciones. Para obesidad 17 países contaban con información; el promedio de ésta fue 4,6%, en el que 4 de ellos presentaron valores sobre 6% y 3 inferiores al 2%. En la mayoría se observó incremento en los últimos a os, el 70% presentó aumento de sobrepeso y el 60% de obesidad, sólo en dos de ellos hubo descenso. Esta situación permite clasificar a los países en 4 grupos: el primero los que presentan bajos valores de exceso de peso y tendencia al descenso; el segundo los que poseen altos valores de déficit de peso y aumento de obesidad; el tercero son los que tienen gran extensión territorial, en que se observa diferenciación geográfica y poblacional en el exceso de peso; y finalmente los que presentaron disminución del déficit y un importante aumento del exceso de peso. En conclusión, no hay dudas sobre la tendencia al aumento del sobrepeso y la obesidad en el ni o, sin embargo, debido a la falta de consenso sobre los criterios diagnósticos los reales niveles de prevalencia están en discusión.
A Reduced Number of mtSNPs Saturates Mitochondrial DNA Haplotype Diversity of Worldwide Population Groups
Antonio Salas,Jorge Amigo
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0010218
Abstract: The high levels of variation characterising the mitochondrial DNA (mtDNA) molecule are due ultimately to its high average mutation rate; moreover, mtDNA variation is deeply structured in different populations and ethnic groups. There is growing interest in selecting a reduced number of mtDNA single nucleotide polymorphisms (mtSNPs) that account for the maximum level of discrimination power in a given population. Applications of the selected mtSNP panel range from anthropologic and medical studies to forensic genetic casework.
Inteligencia: Diferencias de género y relaciones con factores psicomotrices, conductuales y emocionales en ni?os de 5 a?os

Interdisciplinaria , 2010,
Abstract: the study had two goals: (1) to explore gender differences in intelligence during early infancy; and (2) to analyze the relation between intelligence (verbal, nonverbal, global) and self-concept, psychomotricity, and behavioral and emotional variables. the study of the relations between intelligence and these variables is proposed in order to confirm that at early ages, such developmental areas are strongly interrelated, and this will underline the relevance of carrying out integral educational programs in preschool children. in this study, the cognitive definition of intelligence postulated by kaufman and kaufman (1997) was adopted. on the basis of the convergence of various cognitive models and in accordance with the contributions of neurology and cognitive psychology, these authors, conceive intelligence in terms of the individual style of information processing. to a great extent, they consider intelligence to be a question of problem-solving capacities and of the effectiveness of individual information-processing skills. they integrate into the concept of intelligence the theory of fluid intelligence (nonverbal skills and the capacity to solve new problems based on the person's aptitude to perceive relations and complete analogies, skills that are not much affected by culture or learning) and of crystallized intelligence (verbal skills related to academic learning that are supported by knowledge of words and by the formation of verbal concepts, skills that depend to agreat extent on formal schooling and cultural experiences). taking into account the results of previous studies, the investigation proposes five hypotheses: (1) at the age of 5 years, no significant differences in intelligence will be found between boys and girls; (2) intelligence correlates positively with self-concept; (3) intelligence will have significant positive relations with psychomotor development; (4) intelligence will be negatively associated with indicators of emotional stability, and (
ANáLISIS COMPARATIVO PARA LA ECONOMíA MAGALLáNICA DESDE LA PERSPECTIVA DE LA SENSIBILIDAD DE COEFICIENTES TéCNICOS

Abstract: the aim of this paper is to show how changes in sectoral activities affect the output of some of the chilean regions. the magellan region is compared to other three regions: libertador bernando o′higgins, bío bío and los lagos to assess similarities and differences among them. using the field of influence techniques, and the chilean regional input-output tables (ine and mideplan), according to schintke y st?glin (1988) to identify the key sectors and treating the results with tools from graph theory (aroche, 1996; 2002 y 2005). finally, it can be it concluded that, when a major interaction of the activities exists, they increase the alternatives that they allow to accede to an economic successful development, since the degree of spatial interaction to the interior of a region associates with a range of possibilities that allow a growth of the economy.

Magallania (Punta Arenas) , 2008, DOI: 10.4067/S0718-22442008000100007
Abstract: it has always been a recurring theme to be able to establish what the key areas of an economy are, especially under an environment of input-output analysis. this would be caused by two reasons, the first would be related to the leadership that one particular activity can have on the other, what is meant to be motivated by the possible impulse that a particular sector can give to the economic development of a particular area, and on the other side, due to the fact that the concept of branch “key” has been subject to disputes for being very broad and vague, since it depends on the perspective that addresses the issue at hand. this study allows for a multiple-angle hierarchically of the importance of economic activities in the region of magallanes and the chilean antarctic. in order to do that, input-output tables developed by the ine-chile and mideplan are used, and which data refer to 1996. firstly, a linkage analysis is presented, and various techniques are used for identification [rasmussen (1956), chenery and watanabe (1958), hazari (1970), cella (1985), sonis et al (1995), dietzenbacher and van der linden (1997) and soza (2007)]. the answers are finally combined to obtain some synthetic indicators, which facilitate their interpretation as well as avoiding a profusion of results. secondly, the sensible of technical coefficients is determined using the schintke and st?glin proposal (1988), which has identified the importance of a branch in terms of its elasticity, given the number of more sensible coefficients presented in columns as well as rows, and depending on the alteration of each of the separate factors and following aroche4s approach, in the sense of using graph theory (1996; 2002 and 2005), influence fields for have been identified each activity after carrying out all of the above, and based on the main results achieved, the following step was the identification of those groups which generate evolvement in the region studied.
LA IDENTIDAD MAGALLáNICA DADOS LOS PRINCIPALES CAMBIOS ECONóMICOS Y ESTRUCTURALES OCURRIDOS EN CHILE ENTRE 1960 Y 2008

Magallania (Punta Arenas) , 2010, DOI: 10.4067/S0718-22442010000100007
Abstract: the present work consists in identifying the economic activity or activities that have contributed to the development of the magellan region. for this we recognize two variables, the internal gross product (pibr) and employment by branch of economic activity (pea). in this intention, we consider two time horizons, one from 1960 to year 2006 for the first variable and, from 1986 to 2008, for the second. results help us establish the most representative economic activities in the functioning regional production. also, some repercussions are advanced in relation to a possible economic shock, which in this economy can happen as soon as these are implemented, in a caeteris paribus scene. nowadays the magellan region, on the basis of its pea, is identified with branches linked to services, where as the pibr focuses on mining and manufacturing industry. on the other hand, we perceive that magellan has specialized itself in activities of rapid regional growth, but slow in a national level.
Sele??o de técnicas de previs?o de mercado segundo as diferentes categorias de novos produtos
Sampron, Dario Amigo;
RAE eletr?nica , 2005, DOI: 10.1590/S1676-56482005000200007
Abstract: market forecasting for new products is a difficult task. some of the reasons are the large number of techniques available for forecasting and the scarce orientation on the best techniques to apply. difficult increases because most of the literature on new product forecasting focuses on the techniques and not on the management issues, such as discussing when to employ the technique. this article aims to guide practitioners on the techniques to be applied in specific situations. the approach assumes there are different categories of new products and that a market forecasting is divided up in steps. each combination of new product category and job step can define specific techniques to be adopted. due to the extension of the subject, suggestions for future research are also indicated.
ENCADENAMIENTOS Y SIMILITUDES ESTRUCTURALES PARA LAS REGIONES DE CHILE
SOZA-AMIGO,SERGIO;
Revista de análisis económico , 2011, DOI: 10.4067/S0718-88702011000200004
Abstract: many authors stress the importance of relationships between sectors for the economic growth. therefore the concept of linkage appears in the definition of two of the most traditional concepts in the input-output analysis: the "key sector" and cluster. in this paper, key products and activities are identified for the chilean regions, the clusters that form and the structural similarity that exists between them. for this, we use a combination of so-called important coefficients and fields of influence. the results indicate that the regions that are most similar are: tarapacá and antofagasta, biobío and los lagos. besides the "developed" regions concept that is associated with a high division of labor and coordination between sectors, they have similar production structures and are very different from those that have "less development".
