Innovative Applications : Open Educational Resources and Mobile Resources Repository for the Instruction of Educational Researchers in Mexico

The movement of Open Educational Resources (OER) is one of the most important trends that are helping education through the Internet worldwide. "Tecnológico de Monterrey" (http://tecvirtual.itesm.mx/) in Mexico, with other Mexican higher education institutions, is creating an Internet/web based repository of OERs and Mobile Resources for the instruction and development of educational researchers at undergraduate, Master's and Doctoral level. There is a lack of open educational resources and material available at the Internet that can help and assist the development and education of educational researchers in Spanish speaking countries. This OER repository is part of a project that is experimenting new technology for the delivery of OERs from one repository (http://catedra.ruv.itesm.mx/) through an indexed OER catalog (http://www.temoa.info/) to mobile devices (Ipod, Iphone, MP3, MP4). This paper presentation will describe and comment about this project: outcomes, best practices, difficulties and technological constraints.

¿La cultura es un factor que influye en la percepción de las marcas? :Caso: La imagen de marca-país de México entre los turistas españoles

Aquest treball presenta un model comparatiu d’anàlisis de la marca en base a l’inconscient col•lectiu, teoria desenvolupada per C. G. Jung (1991), adequat per Sabrine Dornelles (2010) a l’estudi de les marques comercials i contrastat en aquest treball amb la proposta d’aproximació al Perfil Arquetípic Azteca. Per aquesta raó, s’ha realitzat una revisió bibliográfica en referencia a l’objecte de l’estudi del posicionament de la marca, i en especial, dels atributs vinculats al perfil azteca. Amb l’objectiu de conèixer si la cultura influeix o no, en la percepció d’una marca, s’ha realitzat un pre-test via online amb subjectes de nacionalitat espanyola i de països d’Amèrica llatina (Argentina, Colòmbia, Equador, Perú, República Dominicana i Veneçuela) per al grup de control. 5 Els resultats han sigut tractats tant a nivell d’estadística descriptiva com a mode inferencial. Les dades amb significació p≤ 0,05 mostren els estímuls (atributs) que foren associats o no, amb la marca del país Mèxic. Mentre que l’arquetip occidental (grec) va permetre en major percentatge valorar la marca amb tots els subjectes (espanyols, mexicans i llatins) l’arquetip prehispànic no dóna significació suficient amb els espanyols i llatins, però en canvi aporta matisos en el cas dels mexicans. En referència a l’esmenta’t anteriorment , cal que el proper pas sigui millorar el perfil d’arquetipus azteca.

Y-chromosome diversity in native mexicans reveals continental transition of genetic structure in the Americas

The genetic characterization of Native Mexicans is important to understand multiethnic based features influencing the medical genetics of present Mexican populations, as well as to the reconstruct the peopling of the Americas. We describe the Y-chromosome genetic diversity of 197 Native Mexicans from 11 populations and 1,044 individuals from 44 Native American populations after combining with publicly available data. We found extensive heterogeneity among Native Mexican populations and ample segregation of Q-M242* (46%) and Q-M3 (54%) haplogroups within Mexico. The northernmost sampled populations falling outside Mesoamerica (Pima and Tarahumara) showed a clear differentiation with respect to the other populations, which is in agreement with previous results from mtDNA lineages. However, our results point toward a complex genetic makeup of Native Mexicans whose maternal and paternal lineages reveal different narratives of their population history, with sex-biased continental contributions and different admixture proportions. At a continental scale, we found that Arctic populations and the northernmost groups from North America cluster together, but we did not find a clear differentiation within Mesoamerica and the rest of the continent, which coupled with the fact that the majority of individuals from Central and South American samples are restricted to the Q-M3 branch, supports the notion that most Native Americans from Mesoamerica southwards are descendants from a single wave of migration. This observation is compatible with the idea that present day Mexico might have constituted an area of transition in the diversification of paternal lineages during the colonization of the Americas.

Linguistic and maternal genetic diversity are not correlated in native mexicans

Mesoamerica, defined as the broad linguistic and cultural area from middle southern Mexico to Costa Rica, might have played a pivotal role during the colonization of theAmerican continent. It has been suggested that the Mesoamerican isthmus could have played an important role in severely restricting prehistorically gene flow between North and SouthAmerica. Although the Native American component has been already described in admixedMexican populations, few studies have been carried out in native Mexican populations. In thisstudy we present mitochondrial DNA (mtDNA) sequence data for the first hypervariable region (HVR-I) in 477 unrelated individuals belonging to eleven different native populations from Mexico. Almost all the Native Mexican mtDNAs could be classified into the four pan-Amerindian haplogroups (A2, B2, C1 and D1); only three of them could be allocated to the rare Native American lineage D4h3. Their haplogroup phylogenies are clearly star-like, as expected from relatively young populations that have experienced diverse episodes of genetic drift (e.g. extensive isolation, genetic drift and founder effects) and posterior population expansions. In agreement with this observation is the fact that Native Mexican populations show a high degree of heterogeneity in their patterns of haplogroup frequencies. HaplogroupX2a was absent in our samples, supporting previous observations where this clade was only detected in the American northernmost areas. The search for identical sequences in the American continent shows that, although Native Mexican populations seem to show a closer relationship to North American populations, they cannot be related to a single geographical region within the continent. Finally, we did not find significant population structure on the maternal lineages when considering the four main and distinct linguistic groups represented in our Mexican samples (Oto-Manguean, Uto-Aztecan, Tarascan, and Mayan), suggesting that genetic divergence predates linguistic diversification in Mexico.

African signatures of recent positive selection in human FOXI1

Background: The human FOXI1 gene codes for a transcription factor involved in the physiology of the inner ear, testis, and kidney. Using three interspecies comparisons, it has been suggested that this may be a gene underhuman-specific selection. We sought to confirm this finding by using an extended set of orthologous sequences.Additionally, we explored for signals of natural selection within humans by sequencing the gene in 20 Europeans,20 East Asians and 20 Yorubas and by analysing SNP variation in a 2 Mb region centered on FOXI1 in 39worldwide human populations from the HGDP-CEPH diversity panel.Results: The genome sequences recently available from other primate and non-primate species showed that FOXI1divergence patterns are compatible with neutral evolution. Sequence-based neutrality tests were not significant inEuropeans, East Asians or Yorubas. However, the Long Range Haplotype (LRH) test, as well as the iHS and XP-Rsbstatistics revealed significantly extended tracks of homozygosity around FOXI1 in Africa, suggesting a recentepisode of positive selection acting on this gene. A functionally relevant SNP, as well as several SNPs either on theputatively selected core haplotypes or with significant iHS or XP-Rsb values, displayed allele frequencies stronglycorrelated with the absolute geographical latitude of the populations sampled.Conclusions: We present evidence for recent positive selection in the FOXI1 gene region in Africa. Climate mightbe related to this recent adaptive event in humans. Of the multiple functions of FOXI1, its role in kidney-mediatedwater-electrolyte homeostasis is the most obvious candidate for explaining a climate-related adaptation.

Oil and economy in Mexico, 1900-1930s

This brief essay reviews the macro framework of oil and economy in Mexicoin the early days of the oil industry, from 1900 to 1938. The first sectiondisplays the figures of production at the world level and shows how Mexicobecome a major oil producer in the 1920s. The second section look at theMexican economy of the first third of the century followed by a thirdsection on the importance of the oil sector in terms of trade and fiscalincome. The last section reviews the literature and the outlooks of thecontemporaries over the development of the oil industry in the early partof the 20th century. The paper will be of use for those producing in depthanalyses of the Mexican oil industry in this period.

The role of Mexico in the first oil shortage: 1918-1922, an international perspective

In 1921 Mexico produced a quarter of world s petroleum, making the country the secondlargest producer in the world, but by 1930 it only accounted for 3 per cent of world sproduction. To date the discussion has mostly relied on events taking place in Mexico forexplaining the decline of the industry. Very little attention has been placed todevelopments in petroleum industry elsewhere, except Venezuela. Practically noattention has been paid to the reasons for the rise of oil output in Mexico. This neglectsthe massive changes taking place in the petroleum industry worldwide during the GreatWar years and its aftermath, and overall ignores the shortage of oil that occurred in theworld s markets between 1918-1921. These are crucial events in order to understand theearly rise of the Mexican oil industry and set the basis for a better understanding of thesubsequent sudden decline.

Dialectología y paremiología: refranes meteorológicos y variación diatópica en la Romania

A partir de los materiales de BADARE (Base de datos sobre refranes del calendario y meteorológicos en la Romania), esta contribución reivindica el enorme interés de estudiar la variación diatópica en dicho tipo de paremias, y abre una línea de investigación que podríamos denominar"dialectología paremiológica". A partir de la muestra que aquí ofrezco, se observa que tales paremias albergan componentes individuales de índole fonética, morfosintáctica y derivativa, léxica y semántica que responden a una adscripción dialecta l concreta; y, asimismo, que las propias paremias, como entidades globales, dan pie en algunos casos a identificar"tipos parémicos" o"paremiotipos" relacionables con determinadas zonas de uso: áreas parémicas dialectales que constituyen uno de los principales objetos de atención de la"geoparemiología romance"

Paremiología española e hispanoamericana. Los americanismos parémicos

Desde mediados del siglo XX se plantea en español el debate teórico en torno al concepto de americanismo léxico, que se entiende de distintas formas en función del criterio adoptado. Sea como sea, resulta patente que existe un fondo léxico general al lado de numerosas voces particulares de determinadas variedades diatópicas. En este artículo se extiende el análisis a la paremiología y, después de la caracterización general de los refranes y de la reflexión sobre la actualidad de su uso en español, se aborda la variación geográfica que despliegan. Se argumenta que, al igual que existe un fondo panhispánico de refranes, producto del trasplante desde España hacia América, se han producido también reformulaciones del caudal heredado o nuevas acuñaciones en distintos territorios del Nuevo Mundo, de las que se ofrecen numerosos ejemplos y para las que se propone el uso de la etiqueta americanismo parémico, en paralelo a la ya tradicional de americanismo léxico.

A aldraxe proverbial da preguiza nas dúas versións españolas de The Way to Wealth de Benjamin Franklin

A admiración que destilou no seu tempo e durante o século XIX o bo sentido común das obras de Benjamin Franklin (1706-1790) plasmouse na tradución dos seus libros a un considerable número de linguas. The Way to Wealth (El camino de la fortuna o Cómo hacerse rico), publicado en 1758, contén máis de cen máximas que instan ao traballo honrado, á orde e ao aforro, condenando calquera sinal de preguiza ou desidia. O noso corpus nútrese dunha selección de trece aforismos que teñen relación precisamente con este vicio que condena á miseria, a preguiza. En cambio, o home de ben que aplique as virtudes contidas en The Way to Wealth, aconselladas a modo de refráns, verá, segundo o autor, prosperar esplendidamente a súa economía. Pretendemos analizar, dende os puntos de vista tradutolóxico e contrastivo, o corpus de dúas traducións españolas deste libriño de Franklin: unha anónima, publicada en Barcelona, en 1891; e a de Alberto Lena de 1999.

Recursos naturales y género. El caso de la comunidad Once de Mayo (Campeche, México)

Este estudio pretende realizar una aproximación al papel de la cooperación en el empoderamiento femenino sobre los recursos naturales en la comunidad rural mexicana Once de Mayo. Para ello se analizan las experiencias de doce participantes en proyectos destinados a mujeres utilizando como medios la historia de vida, la observación participativa y los talleres. De todo ello se desprende la importancia de que los programas y/o proyectos aborden las necesidades prácticas de las mujeres, vinculadas a su hogar, sin omitir sus necesidades estratégicas de género como elementos para el empoderamiento. Además, para el empoderamiento femenino a través de la cooperación es fundamental el desarrollo de actitudes de liderazgo por parte de alguna/as de las participantes y el propio interés de todas las involucradas en colaborar, además de sus experiencias previas de capacitación en diferentes temáticas.

Geografías familiares bajo la dictadura franquista: exilio, clandestinidad, prisión

Este texto ahonda en las geografías políticas, sociales y familiares de Aurèlia Pijoan, la primera mujer que, médico de profesión, ha accedido a un cargo de representación municipal en Lleida. Casada con Luis Pérez García-Lago –secretario general del PSUC y la UGT en la Lleida de los años trenta y posteriormente máximo responsable del partido en el exilio mejicano-, continuó su compromiso a través de la Unión de Mujeres Españolas de México de la que llegó a convertirse en secretaria general. El artículo pretende, a la vez que reflexionar sobre el diálogo que se establece entre recuerdo y olvido, hacer visible la historia de los sin historia a partir de un centro de gravedad concreto, puesto que los itinerarios personales y familiares de Aurèlia Pijoan permiten recorrer las diversas caras del universo represivo franquista: exilio,clandestinidad y prisión.

Reconstructing native American migrations from whole-genome and whole-exome data.

There is great scientific and popular interest in understanding the genetic history of populations in the Americas. We wish to understand when different regions of the continent were inhabited, where settlers came from, and how current inhabitants relate genetically to earlier populations. Recent studies unraveled parts of the genetic history of the continent using genotyping arrays and uniparental markers. The 1000 Genomes Project provides a unique opportunity for improving our understanding of population genetic history by providing over a hundred sequenced low coverage genomes and exomes from Colombian (CLM), Mexican-American (MXL), and Puerto Rican (PUR) populations. Here, we explore the genomic contributions of African, European, and especially Native American ancestry to these populations. Estimated Native American ancestry is 48% in MXL, 25% in CLM, and 13% in PUR. Native American ancestry in PUR is most closely related to populations surrounding the Orinoco River basin, confirming the Southern American ancestry of the Taíno people of the Caribbean. We present new methods to estimate the allele frequencies in the Native American fraction of the populations, and model their distribution using a demographic model for three ancestral Native American populations. These ancestral populations likely split in close succession: the most likely scenario, based on a peopling of the Americas 16 thousand years ago (kya), supports that the MXL Ancestors split 12.2kya, with a subsequent split of the ancestors to CLM and PUR 11.7kya. The model also features effective populations of 62,000 in Mexico, 8,700 in Colombia, and 1,900 in Puerto Rico. Modeling Identity-by-descent (IBD) and ancestry tract length, we show that post-contact populations also differ markedly in their effective sizes and migration patterns, with Puerto Rico showing the smallest effective size and the earlier migration from Europe. Finally, we compare IBD and ancestry assignments to find evidence for relatedness among European founders to the three populations.

Per Santa Llúcia, un pas de puça. Crecer y decrecer de los días, refranes del calendario, Romania continua

Hace años que me ocupo, con creciente interés, de los refranes del calendario en el ámbito de la Romania. Al cabo de un tiempo de ir advirtiendo afinidades entre paremias romances relativas al curso del año, me decidí a escribir un par de artículos (Gargallo, 1998a, 1998b) sobre las referidas al día de Santa Lucía (13 de diciembre), fecha vinculada secularmente al solsticio de invierno y a la recuperación de la luz solar. En ambos artículos contemplo esta jornada de Santa Lucía como el arranque de una serie de paremias o refranes que expresan por diversos medios el crecer de los días en jalones que recorren el mes de diciembre restante, a continuación el de enero, y pierden su rastro allá por febrero, no lejos de la igualación de días y noches, del equinoccio primaveral.

Refráns meteorolóxicos e atlas románicos, paremioloxía e territorio

Tras unha presentación da Base de datos sobre refranes del calendario y meteorológicos en la Romania (BADARE) e do progresivo baleirado nela de diversos atlas lingüísticos da Romania, preséntanse tres mostras da variación diatópica deste tipo de refráns no espazo iberorromance: (1) coa implicación do arco da vella, (2) dos roibéns e (3) das imaxes de ceo ovellado e afíns. Cómpre destacar o grande interese dos materiais contidos nos atlas románicos, que se poden complementar cos doutras obras vinculadas á lingua e ao territorio: repertorios paremiográficos, monografías dialectais, achegas diversas. Aínda que non parece factible un grande atlas paremiolóxico romance nin sequera de segunda xeración, pois os refráns (meteorolóxicos o de outros tipos) son nos atlas de primeira xeración unha propina ocasional, coidamos que mediante a base de datos BADARE se poden administrar eses materiais de xeito que faciliten o estudo da paremioloxía románica ligada ao territorio.
