Abstract: This article is the first report of equine cholangiocarcinoma in Colombia. A 14 years old horse was referred to the Large Animal Clinic at the National University of Colombia, with history of weight loss; on examination, the horse was letarghic, in poor body condition, with abdominal distention and ventral edema. The clinical examination suggested a hepatic tumor as a very probable diagnosis; the clinical pathology results showed severe involve -ment of biliary ducts and hepatic cells. The necropsy and the microscopic examen revealed cholangiocarcinoma. Este art -culo representa el primer reporte de colangiocarcinoma en un equino en Colombia. Esta neoplasia fue diagnosticada en un equino de 14 a ±os de edad remitido a la Cl -nica de Grandes Animales de la Universidad Nacional de Colombia, con historia de p rdida de peso cr 3nica. En la evaluaci 3n cl -nica se encontraron como hallazgos m s relevantes depresi 3n, condici 3n corporal pobre, distensi 3n abdominal severa y edema ventral; se plante 3 como diagn 3stico diferencial m s probable tumor hep tico; los resultados de laboratorio revela -ron severo compromiso de conductos biliares y hepatocitos. En la necropsia e histopatolog -a se confirm 3 el diagn 3stico de colangiocarcinoma.

Abstract: Most approaches to variability in Optimality Theory have attempted to make variation possible within the OT framework, i.e. to reformulate constraints and rankings to accommodate variable and gradient linguistic facts. Sociolinguists have attempted to apply these theoretical advances to the study of language variation, with an emphasis on language-interna1 variables (Auger 2001, Cardoso 2001). Little attention has been paid to the array of externa1 factors that influence the patterning of variation. In this paper, we argue that some variation pattems-specially those that are socially meaningful- are actually the result of a three-grarnmar system. G, is the standard grammar, which has to be available to the speaker to obtain these variation patterns. G; is the vernacular grammar, which the speaker is likely to have acquired in his local community. Finally, G, is an intergrammar, which is used by the speaker as his 'default' constraint set. G is a continuous ranking (Boersma & Hayes 2001) and domination relations are consciously altered by the speakers to shape the appropriate and variable linguistic output. We illustrate this model with analyses of English and Spanish.

Abstract: Tesar & Srnolensky's book is a valuable reference for traditional approaches to leamability within an Optimality Theory framework. It summarises the reflections of two of the 'founder members' of the discipline. However, other researchers have developed altemative algorithms based on the previous work presented in Tesar & Smolensky which, in our opinion, are more realisfic insofar as they can cope with variation and developmental instability (Boersrna & Hayes 2001). Another interesting question, which affects all computational approaches to leamability, is whether such theories are really grounded or not. Now we know that computers can actually work out the constraint ranking of a language starting frorn some (but not al]) initial hierarchies, provided that they are given sufficient overt information. Does that really mean that this is the way the human mind works?. We cannot be satisfied with a simple statement of the type 'if the hurnan mind performed these operations, it would acquire a language'. The only possible answer is that further research on phonological acquisition must be carried out in order to test whether RIPICD and EDCD are indeed at work in phonological acquisition by human beings. Tesar & Srnolensky's Learnability in Opfimality Theory is possibly a must for phonologists. But insofar as the developrnent of OT seems to have wider implications to the extent of having become a revolution in linguistic theory, it is also recomended for linguists in general and specially for applied linguists with some interest in phonological acquisition.
Tiempo y aspecto verbal. Marco teórico para la clase de ELE
Juan Manuel Real Espinosa
MarcoELE : Revista de Didáctica , 2005,
Abstract: En el presente trabajo se analizan las relaciones temporales y aspectuales del verbo en espa ol. Se defiende que el tiempo es una categoría gramatical pertinente con un comportamiento constante en los modos indicativo y subjuntivo, y que se estructura mediante dos pares de oposiciones binarias, que dan lugar a dos niveles o segmentos temporales y a cuatro áreas de significación temporal. Los comportamientos que podríamos considerar ajenos a esta norma, generan de forma regular un contenido modal dentro del mensaje, por lo tanto un mismo procedimiento da cuenta de las relaciones temporales y modales. El aspecto se articula de igual modo en dos pares de oposiciones binarias, que generan dos niveles o segmentos aspectuales y cuatro áreas de significación aspectual. La oposición en el segundo nivel de oposición aspectual genera una cronología relativa. Se proponen procedimientos para emplear en el aula de E/LE esta concepción del sistema verbal. //// In the present paper I analyze the relationship in temporal and aspect of the Spanish verbs. I defend that time is a pertinent grammatical category which has a constant comportment in the indicative and the subjunctive, structured through two pairs of binary oppositions, forming two grades or temporal fragments and four areas of temporal meanings. The comportment that could be considered as not being part of the rule generates a regular form of modal contents within the message; therefore, the same procedure explains the relationship between time and mode. The aspect is articulated in the same way in two pairs of binary oppositions which generate to grades or aspect fragments and four areas of aspect meanings. The opposition in the second aspect grade generates a relative chronology. Procedure are to be proposed use this verbal system concept in E/LE classes.
Incidencia del género y la edad en la creatividad infantil

Diversitas: Perspectivas en Psicología , 2005,
Abstract: it was studied the creativity in 115 children with the creativity test developed by de zubiría, marlés y ramírez (2003) and it was identified both gender and age incidence in the subject's scores. in addition, it was estimated reliability and validity of this test. the results indicate that gender does not represent a significant effect over test's scores; while the age is a relevant factor in children's creativity processes. recommendations about specificity in the age's score tables to this test are done.

Abstract: in the course of universal history ii at the university of quintana roo in the 7th semester of the bachelors program of humanities during the summer of 2007 students were given to read the historical novel from umberto eco in the name of the rose. this was done with didactic purposes in order to introduce the students to the middle ages and to teach them which specific part of this era and culture arrived in the new spain in the xvi century; i.e. scholastic philosophy, the castilian language, the latin language, and the catholic religion among other cultural aspects. it is important to consider that many of our students come not only from urban areas but from rural ones as well and in many cases they have a mayan background and many of them even speak the mayan language. this is one of the most important aspects to be considered while teaching courses of this nature; for many students this will be their first time encountering with this sort of knowledge new to them since it is not taught in any previous educational levels in the state of quintana roo, mexico.

Abstract: En la materia de Historia Universal II -semestre verano 2007- de la Universidad de Quintana Roo, se les pidió a los estudiantes de la Licenciatura en Humanidades la lectura de la novela histórica de Umberto Eco, El nombre de la rosa, con una finalidad didáctica: que conocieran una parte de la Edad Media y los aspectos socioculturales que llegaron a la Nueva Espa a en el siglo XVI -como la filosofía escolástica, el castellano, el latín, la religión católica, entre otros-, ya que algunos alumnos, que provienen de medios urbanos y rurales, son hablantes del maya -así como sus abuelos-, y este conocimiento para ellos es nuevo, dado que no se los ense aron en los otros niveles educativos en esta región del sur de Quintana Roo.

Abstract: Background: It is postulated that the concentrations of the major strong ions (Na, K, and Cl) in oral electrolyte solutions play a major role in clinical efficacy of these solutions for rehydration and corrections of metabolic acid base derangements. Objectives: The purpose of this study was to test prospectively the efficacy of an OES (OESexp) formulated based on concentration of strong ion difference (SID) and propionate in a group of calves with naturally occurring neonatal diarrhea and clinically detectable dehydration and acid base abnormalities. Animals: Ten client owned calves of varying breeds, 2 - 22 days old, presented to a veterinary teaching hospital with a history of naturally occurring acute undifferentiated diarrhea, progressive depression and dehydration for treatment. Methods: Clinical and laboratory parameters were measured pre and post two oral electrolyte treatments to assess efficacy of the experimental OES to correct clinical and clinico pathological parameters. For the clinical trial the calves served as their own controls. For control of safety of medication 4 normal calves were force fed 4 L of OESexp and followed over a 24 hour period. Results: All calves had severe diarrhea and metabolic acidosis. The metabolic acidosis observed in the plasma of these calves and reflected by pH, HCO3- SID and base deficit was corrected significantly towards reference ranges (p < 0.05) with two 2 L feedings 12 hours apart. Dehydration was significantly corrected and all calves were discharged 1 - 3 days post admission. Conclusion and Clinical Importance: The use of SID is a valid approach when formulating oral electrolytes solutions for use in calves with acute diarrhea and metabolic derangement. Sodium propionate is valid substitute for commonly used sodium base equivalents in North America in oral electrolyte solutions.

Abstract: in order to evaluate the vertical distribution of the heavy metals pb, cd, and zn in sediments associated to rhizophora mangle plants, potentially bioavailable and not bioavailable concentrations of these metals were determined in three sediment cores collected in the sevilla river, ciénaga grande de santa marta. measurements were carried out by inductively coupled plasma-atomic emission spectrometry. the results showed that in sevilla river mangrove ecosystem these metals are accumulated principally in non-bioavailable forms, this means that a great part or them are retained in the sediment. the retention of pb, cd, and zn in the sediments of this mangrove ecosystem is bly related to the physicochemical parameters ph, salinity, and redox potential, and to organic matter, and silt and clays contents.
