Devolviendo el balón a la cancha: Diálogos con Walter Mignolo
Iglesias Turrión,Pablo; Espasandín López,Jesús; Errejón Galván,I?igo;
Tabula Rasa , 2008,
Abstract: this article originated with discussions maintained with walter d. mignolo during the summer course titled “decolonial thought and the surge of indigenous peoples as new political subjects in latin america,” held at el escorial between the 24th and 28th of july, 2006. our primary objective is to continue the debate, organizing and systematizing large part of the arguments that opposed walter’s thesis, to try to present a group of questions and arguments around the notion of epistemic turn. second objective is to provide elements that can be used to create a liberating theoretical cartography that allows articulating and relating the fights and processes of collective action of the attacked subaltern subjectivities in different areas of the planet by the dynamics of domination and exploitation of capitalist modernity, as well as overcoming the euro-centric defects of a large part of the emancipating thought traditions of classic anti-systemic movements. in third place, we ask ourselves the question with which professor heriberto cairo opened the course: it is possible to decolonize europe? we will thus inquire about the possibility of a communication interface between the movements in latin america and europe, and about the radiation of indigenous political cultures outside of their range of immediate insertion.

Abstract: the electoral victory in 2005 of the socialist movement headed by eva morales had a worldwide significance. in this article, we will hold that the political events in bolivia over recent years have to be interpreted as more than a mere change in the country’s political elite. what is happening in bolivia is, in our judgment, the institutional crystallization of a set of processes that converged with the start of a cycle of anti-neo-liberal fights that initiated in the year 2000. the origins and effects of that "rebel cycle" transcend the country scale, even though it represents its most visible space of materialization. in first place, using the perspective of wallerstein’s world-system, we present an explanation of the historical tendencies of transformation of geopolitical power distribution and the integration dynamics of capitalism. we pay special attention to the effects of systemic reordering of neo-liberal globalization since the 1970s. in second place, we examine the effects of neo-liberalism on the geopolitical situation of bolivia and its determining influence on the emergence of indigenous political identities, as well as the crisis of political protagonism of the bolivian miner proletarians, within the framework of impugnation processes of coloniality. in third place, we analyze some aspects of the influence of these elements (global systemic dynamics and transformation of class structures) on the constitutional process currently open in bolivia. we describe the interactions between the political actors that intervene in the constitutional process, paying special attention to the role of social movements.
El regreso de Túpac Katari. Bolivia y los procesos de transformación global del capitalismo

Tabula Rasa , 2007,
Abstract: La victoria electoral en diciembre de 2005 del Movimiento al socialismo encabezado por Evo Morales tuvo una significación mundial. En este artículo defenderemos que los acontecimientos políticos bolivianos de los últimos tiempos deben ser interpretados como algo más que un mero recambio en las elites políticas del país. Lo que está ocurriendo en Bolivia es, a nuestro juicio, la cristalización institucional de un conjunto de procesos que convergieron en la apertura de un ciclo de luchas anti-neoliberales iniciado en el a o 2000. Los orígenes y efectos de este ciclo rebelde trascienden la escala estatal aún cuando ésta represente su espacio de materialización más visible. Een primer lugar, usando la perspectiva del sistema-mundo de Wallerstein, llevaremos a cabo una explicación de las tendencias históricas de transformación en la distribución geopolítica del poder y en las dinámicas de integración del Capitalismo. Prestaremos particular atención a los efectos de reordenación sistémica de la globalización neoliberal desde los a os 70. segundo lugar, examinaremos los efectos del Neoliberalismo en la situación geopolítica de Bolivia y su influencia determinante en la emergencia de las identidades políticas indígenas, así como en la crisis de protagonismo político del proletariado minero boliviano, en el marco de procesos de impugnación de la colonialidad . Een tercer lugar, analizaremos algunos aspectos de la influencia de los elementos anteriores dinámicas sistémicas globales y transformación de la estructura de clases en el proceso constituyente actualmente abierto en Bolivia. Intentaremos describir las interacciones entre los actores políticos que intervienen en el proceso constituyente prestando especial atención al papel de los movimientos sociales
Devolviendo el balón a la cancha. Diálogos con Walter Mignolo
Pablo Iglesias Turrión,Jesús Espasandín López,I?igo Errejón Galván
Tabula Rasa , 2008,
Abstract: El presente artículo tiene su origen en las discusiones mantenidas con Walter Dd. Mignolo en el curso de verano "El pensamiento descolonial y el surgimiento de los indígenas como nuevo sujeto político en América Latina", celebrado en Escorial entre el 24 y el 28 de Julio de 2006. Nuestro primer objetivo es continuar el debate ordenando y sistematizando buena parte de los argumentos que se opusieron a las tesis de Walter para tratar de presentar un conjunto de cuestiones y argumentos frente a la noción de giro epistémico. Nuestro segundo objetivo es aportar elementos para la elaboración de una cartografía teórica liberadora que permita articular y relacionar las luchas y procesos de acción colectiva de las subjetividades subalternas agredidas en diferentes áreas del planeta por las dinámicas de dominación y explotación de la modernidad capitalista, así como superar los defectos euro-céntricos de buena parte de las tradiciones de pensamiento emancipador de los movimientos antisistémicos clásicos. En tercer lugar, nos plantearemos la pregunta con la que el profesor Heriberto Cairo inauguraba el curso: Es posible descolonializar Europa? Indagaremos así sobre la posibilidad de una interfaz comunicadora entre los movimientos de América Latina y Europa y sobre la irradiación de las culturas políticas indígenas fuera de su ámbito de inserción inmediata.
Patterns of Genetic Diversity of the White-Nosed Coati Reveals Phylogeographically Structured Subpopulations in Mexico  [PDF]

Natural Resources (NR) , 2017, DOI: 10.4236/nr.2017.81003
Abstract: Coatis (Procyonidae; Nasua) are considered the only truly social meso-carnivore mammals in Neotropical forests. In Mexico, white-nosed coatis (Nasua narica) are suspected to have undergone population reduction due to habitat loss and fragmentation and led to a lack of genetic adaptability and genetic isolation throughout its range. We examined patterns of genetic diversity and connectivity of five populations of Nasua narica distributed throughout Mexico (n = 60) by sequencing an ≈ 800 bp fragment of the mitochondrial cytochrome-b gene and also by screening 12 microsatellite loci. We found moderate to high levels of genetic variability for both genetic markers. We recorded twenty-two different cytochrome-b haplotypes throughout the 5 sampled areas and found that each of the sampled population of white-nosed coatis in Mexico harbors unique haplotypes and only three haplotypes were shared among two different populations that were closer geographically. All populations had high haplotype diversity (h) (0.968 ± 0.008 (SD)) but lower levels of nucleotide diversity (π) of 0.007 ± 0.001 (SD). All microsatellite loci were polymorphic in all of the populations and the mean number of alleles per locus was 5.033 ± 1.545 (SD) with expected (HE) and observed (HO) heterozygosity values of 0.774 and 0.664, respectively. However, low Wright F statistic values suggest the existence of a reduced heterozygosity (FST = 0.203, FIS = 0.134 and FIT = 0.310). Significant differences between the five populations confirmed isolation by distance, which suggests genetic structure among five subpopulations.
El 15-M como discurso contrahegemónico
I?igo Errejón Galván
Encrucijadas : Revista Crítica de Ciencias Sociales , 2011,
Abstract: El movimiento 15-M ha sido una irrupción inesperada en el panorama político espa ol, que ha conseguido, desde su nacimiento, una enorme atención mediática y marcar en gran medida la agenda política espa ola. En este artículo se defiende que una parte fundamental de su éxito político se debe a su capacidad de alterar las posiciones políticas dadas y generar una nueva identidad, los así llamados “indignados”, que suscitan lealtades relativamente transversales y reordenan el campo político espa ol. Para ello, se analizará el discurso fundamental del 15-M desde los presupuestos y con las herramientas de la Teoría del Discurso y la Hegemonía. Se caracterizarán a grandes rasgos las principales operaciones de generación de sentido que constituyen a los “indignados” y se adelantarán algunas hipótesis sobre los escenarios de futuro.
Neoangiogenesis in early cervical cancer: Correlation between color Doppler findings and risk factors. A prospective observational study

World Journal of Surgical Oncology , 2008, DOI: 10.1186/1477-7819-6-126
Abstract: A total of 27 patients (mean age: 51.3 years, range: 29 to 85) with histologically proven early stage invasive cervical cancer were evaluated by TVCD prior to surgery. Subjective assessment of the amount of vessels within the tumor (scanty-moderate or abundant) and pulsatility index (PI) were recorded. All patients underwent radical hysterectomy and pelvic lymph node dissection. Postoperative treatment (RT or chemoradiotherapy) was given according to risk factors (positive lymph nodes, parametrial and vaginal margin involvement, depth stromal invasion, lymph-vascular space involvement)Tumors with "abundant" vascularization were significantly associated with pelvic lymph node metastases, depth stromal invasion > 10 mm, lymph-vascular space involvement, tumor diameter > 17.5 mm, and parametrial involvement. Postoperative treatment was significantly more frequent in patients with "abundant" vascularization (OR: 20.8, 95% CIs: 2 to 211). The presence of scanty-moderate vascularization with a PI < 0.82 or abundant vascularization with either PI > 0.82 or PI < 0.82 was associated with high-risk group in 94.4% of the cases (OR: 21.2, 95% CI: 1.9 to 236.0)The results are consistent with a relationship between tumor angiogenesis and prognostic factors for recurrence in early cervical cancer. "Abundant" vascularization and PI < 0.82 may be related to postoperative treatment due to risk factors.Angiogenesis has gained much attention in oncology in recent years. It has been shown to be an essential event for tumor growth and metastases [1]. Several studies have demonstrated that tumor angiogenesis is an independent prognostic factor in cervical cancer [2-4]. Therefore, the assessment of this factor would seem to be important when evaluating patients with this disease. However, tumor angiogenesis can only be assessed on the surgical specimen after surgery and therefore its prospective use, as part of the treatment plan is difficult.Transvaginal Color-Doppler Ultrasound (TVCD) al
Food habits of the yellow snapper Lutjanus argentiventris (Peters, 1869) (Percoidei: Lutjanidae) in La Paz Bay, Mexico
Vázquez,Rosa I; Rodríguez,Jesús; Abitia,Leonardo A; Galván,Felipe;
Revista de biología marina y oceanografía , 2008, DOI: 10.4067/S0718-19572008000200008
Abstract: a total of 304 yellow snapper lutjanus argentiventris stomachs were sampled bimonthly from april 2003 to april 2004, of which 44% contained food. we identified 54 prey species. from the index of relative importance (iri), fish eggs (62%), harengula thrissina (23%), porichthys margaritatus (3.3%), and abudefduf troschelii (2.3%) were the prey of greatest importance in its trophic spectrum. in juvenile snappers, the most important preys were unidentified organic matter (32%), the crustacean upogebia pugettensis (29%), penaeid shrimp (6.5%), and fish eggs (5.2%). the levin index determined that the diet breadth was low (bi=0.0002), indicating that it is a specialist predator showing preference for fish eggs and h. thrissina. the same result was found in males (bi=0.0002) and females (bi = 0.0009). although juveniles also showed a low trophic breadth, they preferred unidentified organic matter and u. pugettensis. the morisita-horn index showed considerable overlap in diet between genders (cλ>0.6), though diet overlap was low between juveniles and adults (cλ<0.2) reflecting feeding habitat differences between them.

Emelio Barjau,Jesús Rodríguez-Romero,Felipe Galván,Francisco Gutiérrez
Revista de Biología Tropical , 2012,
Abstract: Para determinar la variación estacional y espacial de la comunidad de peces en ocho localidades alrededor de la Isla San José en el Golfo de California se realizo un estudio ecológico de marzo 2001 a febrero 2002. Además, se utilizaron censos visuales en 48 transectos de 100x5m (500m2). También, se detectaron dos temporadas climáticas: una fría y otra cálida, se observaron 26 608 organismos de 112 especies de 76 géneros de peces. Asimismo, se utilizo el índice de abundancia relativa para determinar las especies más importantes. Febrero fue el mes de menor diversidad y octubre el mayor. De acuerdo con el índice de valor biológico, 13 especies fueron las que obtuvieron un mayor puntaje. En los meses cálidos se presentaron las mismas especies pero en diferente orden y abundancia. Las localidades de la zona oriental de la isla, presentaron un mayor número de especies y abundancia de peces. En el análisis de componentes principales (ACP) la riqueza específica, diversidad, equidad, número de especies y abundancia total se relacionaron con los meses cálidos. Al utilizar el ACP en su forma espacial registro que la localidad Punta Colorada obtuvo una mayor correlación con el número de especies, diversidad y abundancia total. Seasonal and spatial structure of reef fish community in San Jose Island, Gulf of California, México. The Gulf of California is one of the most fish diverse areas of the Tropical Eastern Pacific Ocean. In spite of its economic value, few works have considered fish community studies for optimum management. With the aim to determine the seasonal and spatial variation of fish communities in eight locations around the San Jose Island, some ecological research was conducted from March 2001 to February 2002. For this, visual censuses were used in 48 transects of 100x5m (500m2); specific analysis such as diversity values, the relative abundance and the biological value indexes were undertaken, and a principal component analysis applied. Our results clearly showed two climatic seasons of cold and warm waters. A total number of 26 608 organisms of 112 species and 76 genera of fishes were identified. We used the relative abundance index to determine the most important species, which were: Abudefduf troschelii, Thalassoma lucasanum, Stegastes rectifraenum, Mulloidichthys dentatus, Chromis atrilobata, Lutjanus argentiventris and Scarus ghobban. February was the month with the lowest diversity with a value of 3.12bits/ind. and October was the most diverse (4.13bits/ind.). According to the biological value index (BVI) and considering the climatic seasons,
