Abstract: the construction and maintenance of infrastructure has been identified as one of the main tools for economic development in colombia. this requires huge amounts of investment. recent economic studies in developing countries, such as colombia, have shown that great part of infrastructure projects are financed through investment coming from the private sector. of this, more than half constitutes foreign direct investment. colombia has recently adopted apolicy ofopenness towards foreign investment. through international investment agreements, colombia has committed to protect foreign investment following certain international obligations and standards. great part of the foreign investment needed for the development of infrastructure in colombia will fall under such investment agreements, and will thus be protected by the obligations agreed upon under said agreements. this paper seeks to describe how the actual obligations committed by colombia are not always clear, and sometimes they introduce new concepts that are not well known in colombian law. this is the case, respectively, of the "fair and equitable treatment" and "indirect expropriation". colombia should have caution in its governance offoreign investment, with a view of reducing the risk of being challenged under international arbitration that may result in multimillion disputes; even more in this era of financing projects through foreign direct investment.

Valderrama,José O;
Formación universitaria , 2010, DOI: 10.4067/S0718-50062010000100006
Abstract: some reflections and recommendations on how to organize, to structure and to submit a manuscript to be considered for publication in the journal formación universitaria or other journals with similar scope and subjects are presented. this papers summarizes some concepts presented by the author in a previous communication and discusses some general aspects on articles that are not necessarily based on scientific research but belong to the so-called documented reflection. this type of articles is acceptable in formación universitaria but it is required to include appropriate documentation, similar to that requested in any other main stream journal. this is because it is the documentation that gives the "scientific" support to the article. it is concluded ion the need that authors must follow the instructions for authors established by the journal and by the international community if they want that their papers have good impact once they are published.
Impacto de los cambios de precios relativos en pobreza y desigualdad en Colombia: 1998-2007
Lasso Valderrama,Francisco Javier;
Ensayos sobre POLíTICA ECONóMICA , 2008,
Abstract: based on the estimation of plutocratic and democratic price indexes for colombia, through individual inflation, i found evidence of the anti-poor effect of relative price shifts occurred between december 1998 and december 2007 and its regressivity with respect to income distribution. in 2001, 2002 and 2007 where the annual increases in food prices were above the national average, the inflation was regressive with regard to the income distribution. on the contrary, in 2000 and 2003 food inflation was below the national level and was progressive with regard to income distribution. on average, an increase of 3.5% in food prices, keeping other prices constant, national inflation increases by 1%, generating an increase of 0.62 percentage points in poverty and 0.14 percentage points in extreme poverty. in relative terms, extreme poverty increases by 2.9% while poverty only reaches 1.6%.
?Rumores, miedo o epidemia? La peste de 1913 y 1914 en la costa atlántica de Colombia
Márquez Valderrama, Jorge;
História, Ciências, Saúde-Manguinhos , 2001, DOI: 10.1590/S0104-59702001000200007
Abstract: by the end of the 1800s , international trade and steam navigation made way for the third bubonic plague pandemy, which started in china in 1891 and reached america in 1898. this calamity apparently arrived in colombia's coast between 1913 and 1915, during the apex of pasteur medicine. the deficiencies of colombian public scientific and sanitary apparat, concerning the emerging bacteriology and epidemiology, prevented the government and the medical body from reacting against the fear and rummor of epidemy, which negatively affected the trade. the authorities were also unable to fight this problem with adequate diagnosis, enferms treatment, urban sanitation, and isolation of infected places. these difficulties led to a confrontation between the government and the medical body, inciting an argument about the existence of the plague. this discussion was settled by the north american official medicine that, in its verdict, gave preference to the commercial interests of the united states, ignoring the sanitary urgencies of the colombian atlantic coast.
Principales Aspectos sobre la Preparación de un Artículo para ser Publicado en una Revista Internacional de Corriente Principal
Valderrama,J. O.;
Información tecnológica , 2005, DOI: 10.4067/S0718-07642005000200002
Abstract: some reflexions and recommendations on how to organize, to structure and to submit a manuscript to an editor for publication in a main stream journal, such as the isi and scielo journals, are presented. some of the most relevant aspects related to the title of an article, the abstract, the introduction, the body of the paper, the conclusions and the references, are discussed. some examples on how to write each of these parts and recommendations on how to solve some common problems found during the preparation of a manuscript, are given. the topics discussed could make a manuscript more attractive to referees and editors, who get the first impression by the presentation and organization of the manuscript, to go next to the details. it is concluded that it is necessary that authors must be careful in fulfilling some minimum rules of ethics and quality accepted by the international community if they want their papers to have the expected positive impact.
El Legado de Johannes Diderik van der Waals y su Conferencia Nobel
Valderrama,José O;
Información tecnológica , 2010, DOI: 10.4067/S0718-07642010000500002
Abstract: the author presents the conference that van der waals delivered when he received the nobel prize for physics in 1910. this work is a contribution to the several commemorating activities that are be-ing organized around the world to celébrate the 100 years since van der waals was awarded the máximum prize. the conference summarizes some of the main achievements and in particular the equation of state, the principie of corresponding states and the theory of mixtures. these pioneering ideas of van der waals have influenced several áreas of physics and thermodynamics but in particular these three concepts, which motivated his merited nobel prize. the paper concludes that even after a hundred years since the nobel and more than 125 years since the doctoral thesis, and despite of many other extraordinary advances in physics and thermodynamics, the concepts of van der waals continué more valid than ever.
Un Modelo para la Distribución Racional de la Actividad Académica en una Universidad
Información tecnológica , 2005, DOI: 10.4067/S0718-07642005000300002
Abstract: some ideas and concepts about the work of a university professor are presented and a model to better distribute the academic work in a university is proposed. the model considers the usual activities of any chilean university but can be adapted to any other university in ibero america, in a simple way. the proposal has the main objective of quantifying in the best possible manner the work done by an academician so he or she can do in a proper and efficient way all the activities of a true university: teaching, research and community service, and not only teaching as erroneously considered in several universities. the model has been randomly applied in several iberoamerican universities. all the academicians that have voluntarily collaborated in the tests have ratified the quality of the model and the accuracy of the results.

Abstract: the north-west of urabá gulf in the southern caribbean supports a variety of coral reef zones in conditions of high turbulence and fluctuating turbidity and salinity. sponge composition and density were surveyed and their relationship with physical and structural features of the reef zones were analyzed. in total, 65 demosponges and 1 calcareous sponge species were encountered along belt transects (20 m2) on 11 stations between 1 and 17 m in depth. sponge density in urabá tended to be higher than in other areas with water conditions optimal for coral reef development (i.e. ronacador, serrana and quitasue?o remote oceanic atolls in the sw caribbean, colombia) due possibly to higher concentrations of organic suspended materials discharged from rivers. nevertheless, this effect was not reflected in the urabá`s species richness as just a limited number of species (niphates erecta, iotrochota birotulata and mycale laevis) had high densities. multivariate analyses showed that sponge community composition varies along a depth gradient and across habitats (coral and geomorphological zones), similar to the patterns observed in other caribbean areas. however, marked taxonomic differences between shallow (<4 m) and deeper (>6 m) zones and the great increase of the sponge density below just 6 m, seem to be a unique feature of urabá. the absence of many species and the low abundance of sponges in shallow zones (< 6 m) may be due, not only to the variables associated to low depth, like turbulence, which is periodically very b, but also to great fluctuations in surface salinity due to discharges of the atrato and other local rivers. the shallow and deep stations that had low sponge richness and density, showed the greatest urchin densities (especially echinometra viridis); therefore, it is possible that these urchins may be playing an additional controlling role on sponge populations.
