Assessment of the impact on sediment quality from abandoned artisanal mine runoffs in a semi-arid environment (the Sonora River basin—Northwestern Mexico)

Impact to streams that receive runoffs from the abundant abandoned artisan-scale mines disseminated throughout the middle and upper Sonora river basin in central Sonora state, Northwestern Mexico, was evaluated by determining total concentrations, enrichment factor (EF), geoaccumulation index (Igeo) and geochemical and granulometric fractionations of heavy metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn) in sediment of those streams. Total concentrations of As were also determined. Excluding Fe, the metal found in highest concentrations in all sites was Mn. Findings indicate that sediment enrichment is moderate only for Pb (3.76) and Zn (3.68) in 1 point, and for Cu (3.61) in a different site, out of the 11 points under study. Enrichment is absent or minimal for the remaining elements and sites. Maximum contamination levels as established by Igeo were moderate for Cu (1.14) and lower than moderate for Cu (0.77) and Pb (0.32) in one site each; and absent for all other elements and sites. The granulometric analyses found a close correlation between the percent mass composition of sediment in gravel, sand, clay and silt, and the distributions of metal content in those compartments, with the exception for Cu and, to a lesser extent, Pb. The geochemical fractionation indicates the metal found in the exchangeable fraction in a highest proportion was Mn, while the highest percent in the reducible fraction corresponds to Pb and Mn. At present, sediments of streams in the middle and upper Sonora River basin show a low or null impact on their quality by the sporadic runoffs from abandoned artisan mines they receive.

Documenting a plant invasion: The influence of land use on buffelgrass invasion along roadsides in Sonora, Mexico

Buffelgrass is an African grass commonly established in pastures in arid and semiarid regions as forage for livestock. However, once established in pastures, this grass spreads and invades adjacent habitats. We evaluated buffelgrass cover along invaded roadsides and adjacent lands in the state of Sonora, Mexico to explore how land use affect invasion. Additionally, we evaluated the abundance and influence of buffelgrass in five invaded plant communities. We recorded buffelgrass in 63.6% of the sampled sites along roadsides and in 17.5% of adjacent lands in the state of Sonora. Land use has a significant effect on adjacent roadside buffelgrass cover, probably through propagule pressure. Buffelgrass abundance ranged from 1633 to 10,399 adult plants per hectare and from 0 to 1811 seeds/m2 in invaded plant communities. Our analysis of five invaded sites revealed a significant effect of buffelgrass invasion through a reduction on species diversity. Overall, our data from five sites suggest that buffelgrass invasion in rangelands is having an impact of native plant communities in the state of Sonora.

Desarrollo tecnológico e integración comercial de los productores agrícolas de la Costa de Hermosillo en la globalización

En este trabajo se describen las características del desarrollo tecnológico del sistema agrícola de la Costa de Hermosillo, en Sonora, y su relación con las formas de integración de los productores en las cadenas de valor nacionales y mundiales. Para ello se recolectó, analizó y relacionó información cuantitativa y cualitativa, y se hicieron entrevistas semiestructuradas. El problema de investigación es original y novedoso, está planteado de manera sistemática, y se desarrollan las herramientas teórico-analíticas necesarias para estudiarlo y analizarlo. La limitante es que no da cuenta suficiente del papel de las empresas privadas e instituciones gubernamentales en la gestión del desarrollo tecnológico regional. Los resultados aportan datos cuantitativos y cualitativos valiosos para comprender y dar testimonio de la realidad socioeconómica de la agricultura sonorense. Se concluye que dicho desarrollo tecnológico no ha beneficiado a todos los productores por igual ni de manera suficiente.

ISO 14001 and 26001, Agents of Change in the SME

At present, business strategies in SMEs (Small and medium enterprises) are crucial for consolidation in highly competitive markets, in achieving a better image and in business profitability. One of the strategies that are currently being used and that have a high level of success are the practices focused on sustainability and social responsibility, through standardized standards such as: ISO 14001 and ISO 26001. The literature related to sustainable business is based mainly on the theory of resources and capabilities, and in theory based on Stakeholders. These currents state that companies should focus on profitable strategies to ensure significant and long-term results, in order to achieve organizational and financial results for stakeholders. In this work, the sample consists of 215 companies from the commerce, services and industry sectors, located in the southern region of the State of Sonora in Mexico.The objective of the work is to analyze the influence of ISO 14001 and 26001 standards on the image and profitability of SMEs. The statistical analysis of the data has been carried out through the linear regression technique by OLS (Ordinary Least Squares). The findings prove that the ISO 14001 standard is the one that most influences the improvement of the business image and the level of profitability of the SME. In addition, we discovered that ISO 26001 has a partial influence on the image and profitability of the SME.

Mitochondrial evidence for a new evolutionary significant unit within the Gila eremica lineage (Teleostei, Cyprinidae) in Sonora, Northwest Mexico

espanolPresentamos las afinidades filogeneticas y el codigo de barras del ADN de Gila cf. eremica, una poblacion morfologicamente divergente y geograficamente aislada de G. eremica DeMarais, 1991. Los analisis filogeneticos mitocondriales de cyt–b, cox1 y nd2 muestran la existencia de un patron de clados dentro del linaje de G. eremica, que situa a G. cf. eremica en un clado de identidad especifica que comparte un supuesto ancestro comun con G. eremica, originario de la cuenca del rio Matape. El analisis de codigo de barras, en que se utilizo un metodo basado en caracteres del programa informatico CAOS, mostro siete caracteres puros que diferencian a G. eremica de su congenere regional G. purpurea y un caracter fijo en G. cf. eremica que lo diferencia de G. eremica. Estos resultados y la reciente deteccion de diferencias morfologicas diagnosticas entre G. cf. eremica y G. eremica sostienen la hipotesis de que Gila cf. eremica es una unidad evolutivamente significativa dentro del linaje de G. eremica. EnglishWe present the phylogenetic affinities and DNA barcode of Gila cf. eremica, a geographically isolated and morphologically divergent population from G. eremica DeMarais, 1991. Mitochondrial phylogenetic analyses of cyt–b, cox1 and nd2 show a clades pattern within the G. eremica lineage, placing G. cf. eremica in a clade of specific identity to and sharing a putative common ancestor with G. eremica from the Matape River basin. The barcoding analysis using a character–based approach of CAOS showed seven single pure characters discriminating G. eremica from its regional congener G. purpurea, and one fixed character in G. cf. eremica discriminating it from G. eremica. These results and the recent detection of diagnostic morphological differences between G. cf. eremica and G. eremica support the hypothesis of Gila cf. eremica as an significant evolutionary unit within the G. eremica lineage.

Collaboration, Women’s Work, and the Unfinished Story of a Sonoran Tale Collection

Abstract From 1976–1978, UCLA PhD student Ronald B. Melton travelled to the state of Sonora in Mexico with his wife, Lily Villanueva Melton, to record legends and folktales for his dissertation research, though he died before he was able to complete the project. Historian Miriam Melton-Villanueva (their daughter) and folklorist Sheila Bock discuss key considerations framing their attempts to present the unfinished story of this tale collection, attending specifically to the role of “women’s work” and the dynamics of presence and absence shaping their participation in an ongoing, collaborative research process.

Civil War in the Southwest Borderlands, 1861–1867 by Andrew E. Masich

Reviewed by: Civil War in the Southwest Borderlands, 1861–1867 by Andrew E. Masich Lance R. Blyth (bio) Civil War in the Southwest Borderlands, 1861–1867. By Andrew E. Masich. (Norman: University of Oklahoma Press, 2017. Pp. 464. Paper, $26.95.) "From 1861 to 1867 the diverse peoples—Indian, Hispano, and Anglo—of the Southwest Borderlands struggled for survival and dominance in civil wars, quite apart from the Civil War of the Southern rebellion that raged in the eastern United States" (3). So begins Andrew E. Masich's Civil War in the Southwest Borderlands, which examines the fighting in the southwestern United States and northern Mexico that took place from the start of the U.S. Civil War in 1861 to discharge of the last New Mexico volunteer in 1867. The Southwest Borderlands was a vast theater of war, the combatants, as I have noted elsewhere, far more peoples than armies. Masich's first chapter covers these peoples. He identifies some twenty-seven different native societies, speaking languages from six different groups. To the familiar roll of Apaches, Navajos, and Comanches, Masich adds the Yumans (Quechans and Mojaves) and their antagonist Pima and Papago (Akimel and Tohono O'odham) neighbors. Other peoples included the Hispanos, ethnic Mexican U.S. citizens of New Mexico and Arizona; Anglos, non-Hispano U.S. citizens; and Mexicans of the border states of Sonora and Chihuahua. He notes that all the peoples of the Southwest Borderlands shared a "martial masculinity" in which men found violence a usable way to gain and maintain access to resources and, I would add, to reproductive opportunities (31). Thus "ethnic rivalries, competition for resources, and deeply rooted warrior traditions" underlay the fighting in the Southwest Borderlands (37). Masich then moves to the start of the Civil War, noting that it "created a great power vacuum" in the region with the withdrawal of federal troops and the diversion of local, state, and federal attention (38). Among those seeking to fill the absence were Chiricahua Apaches, who had clashed with the U.S. before 1861, particularly in what would become the territory of Arizona. As Texan forces prepared to seize the Southwest, California Volunteer regiments mobilized to stop them, leading to an Anglo invasion of the Southwest, with the Californians coming across the deserts from the west and the Texans from the east. The Texan invasion ultimately failed, foiled [End Page 319] by distance, logistics, and the intervention of the Colorado Volunteers in New Mexico, and the Texans retreated, leaving both the Southwest and the story. Masich then takes up the tale in 1863 with Christopher "Kit" Carson's campaigns against the Mescalero Apaches and Navajos and continuing campaigns in Arizona against the Western and Chiricahua Apaches. He notes that the fighting hardened into a series of retaliations by all sides, with Indian revenge falling hardest on the Hispano inhabitants. "By 1865," Masich writes, "the clashes over power and dominance among ethnic groups and nations had increased, and the level of violence had also risen" (197). Starting in 1864, as the U.S. Civil War was coming to an end, Plains Indians—Cheyennes, Comanches, Kiowas—attacked supply trains and settlers along the routes to Denver and into New Mexico. Campaigns to stop these raids resulted in the First Battle of Adobe Walls, where Carson was nearly defeated, and the massacre at Sand Creek. In Arizona, Pimas, Papagos, and Hispanos formed a multiethnic battalion to seek out Apaches, Yavapais, and Hualapais. Masich concludes that "the American Civil War had triggered multiple wars in the Southwest Borderlands during the 1860s," which "transformed the region's communities" (262). By 1867, Anglos were unquestioningly militarily, economically, and politically dominant in the Southwest, whereas in 1861 they had been one people among many. The greatest contribution of Masich's work is that we now have a single-volume history of the Southwest Borderlands during the Civil War from which other scholars may depart or disagree. In full disclosure, I made tentative attempts several years back at a similar project but failed to make any headway, so I applaud the accomplishment. Masich also adds extensive coverage of Arizona to the typically New Mexican focus of most works. He...

Shame, Empathy, Coping and School Safety of the Bystanders in Situations of Bullying

Abstract Unjustified aggression is a problem that exists in schools and represents an obstacle for achieving the goals pursued by education. The goal of this article is to explain how shame, empathy, coping style and school safety discriminate between defensive and reinforcing observers in the face of a hypothetical situation of school bullying. 505 students from public, technical and federal secondary schools of the State of Sonora with ages ranging from 12 to 17 years participated in this study. Of this sample 131 were considered defenders and 374 reinforcers. The results show that the recognition of shame, affective empathy, confrontative coping and school safety explain up to 71.4% the differences between the defensive observers and the reinforcers. It is concluded that the variables considered as predictors can differentiate between the types of observers and represent a valuable contribution in the analysis of bullying as a group process.

Experience in the surgical treatment of juvenile nasopharyngeal angiofibroma at the Hospital de Especialidades No. 2 “Lic. Luis Donaldo Colosio Murrieta”, Mexican Social Security Institute, Ciudad Obregón, Sonora

Objetivo: Exponer nuestra experiencia y evaluar la recurrencia en el manejo quirurgico del angiofibroma nasal juvenil, abordaje abierto contra endoscopico, en el servicio de otorrinolaringologia del noroeste del pais. Materiales y metodos: Estudio observacional, retrospectivo, analitico. Se revisaron los expedientes clinicos de los pacientes con diagnostico de angiofibroma nasal juvenil de 2014 a 2017, atendidos en el Servicio de Otorrinolaringologia y Cirugia de Cabeza y Cuello de esta institucion. Resultados: Un total de 19 pacientes con diagnostico de angiofibroma nasal juvenil, fueron sometidos a un procedimiento quirurgico, 14 abiertos y 5 endoscopicos, la recurrencia fue de 50 % y 40 % respectivamente, lo cual no fue estadisticamente significativo (p=0.88). No obstante, se contrastaron otras variables, como la necesidad de la Unidad de Cuidados Intensivos (UCI) para ambos grupos, 71 % en abordaje abierto y 20 % para el endoscopico, en lo cual si encontramos diferencia significativa (p=0.04). Conclusiones: El estudio no muestra una ventaja estadisticamente significativa del abordaje endoscopico frente al abordaje abierto, pero si una menor necesidad de hospitalizacion en UCI, lo que reduciria los costos de atencion.

Biotechnological potential of bacteria isolated from cattle environments of desert soils in Sonora Mexico

The aim of this research was to study the hydrolytic potential of bacteria isolated from cattle environments of two desert soils in one of the driest and hottest zones in America. A total of 26 points were sampled, 144 strains were isolated, and 50 strains were selected for the characterization of esterase, lipase, protease, and amylase activities and for 16S rRNA identification. Strains of the Bacillus, Pseudomonas, Acinetobacter, Enterobacter, Providencia, Escherichia, and Pantoea genera were identified. Comparisons of the proteolytic activity of the secretome from 14 strains (Bacillus n = 7, Escherichia n = 2; Providencia, Pseudomonas, Enterobacter, Pantoea and Acinetobacter n = 1) were performed. Four strains of Bacillus showed the highest proteolytic activity. These strains were characterized through a comparative analysis of pH and temperature as well as the effects of salt concentration on protease activity. Maximum proteolytic activity occurred in the range of pH 7-9 and temperatures between 50 and 70°C for B. subtilis WD01, B. tequilensis WS11, B. tequilensis WS13, and B. tequilensis WS14. At a 20% NaCl concentration, the proteolytic activity retained was 71.4%, 65%, and 79.8% for WD01, WS11, and WS13, respectively; the activity of strain WS14 increased with 45% NaCl. Protease production by B. tequilensis WS14 with wheat, fish, and bone flours as low-cost substrates showed no differences between bone and fish flours and showed a decrease in protease production with wheat flour. The proteolytic activity in flour extracts with 20% NaCl was 82%, 75.61% and 38.04% for fish, bone and wheat flours, respectively. Data obtained in this work allow us to propose that strains isolated from environments with extreme conditions have a biotechnological potential.

De alienígenas chinos e indígenas yaquis (ubicando el constitucionalismo latinoamericano)

He aquí un par de casos pretéritos en busca de una categoría actual. Los casos son el del pueblo yaqui en México, entre su hostigamiento y supeditación en Sonora y su deportación y esclavización en Yucatán, y el de la inmigración china y su tratamiento severísimamente discriminatorio, hasta la expulsión, en el mismo Estado de Sonora. La categoría es aquella que pudiera ser capaz de caracterizar el constitucionalismo latinoamericano por la recurrencia de casos similares respecto tanto a pueblos indígenas como a contingentes de inmigraciones no europeas. Al propósito se toma también en cuenta a los Estados Unidos. Entre casos y categoría, se considera la condición constitucional o, dicho mejor, el estatus extraconstitucional, durante el siglo XIX, de los llamados culíes, de otros trabajadores importados, de esclavos emancipados y, a su vez, como presencia humana más relevante para el mismo núcleo del constitucionalismo, de los pueblos indígenas, en cuyo contexto la historia constitucional latinoamericana se revela como una especie de reciclaje e incluso potenciación del legado colonial europeo por Estados independientes. Dicho de otro modo, a lo largo y ancho de las Américas, el colonialismo puede ser un factor de primer orden en la formación y el desenvolvimiento del constitucionalismo.

CENEB Oro C2017: nueva variedad de trigo duro para el noroeste de México

El cultivo de trigo cristalino o duro (Triticum durum L.) es una de las actividades agrícolas que genera mas riqueza en el estado de Sonora, porque este tipo de grano se comercializa en el mercado internacional. En el año 2017, dicho estado exportó este cereal por 176.3 millones de dólares, que representan 6.6% de las exportaciones agrícolas con destino a Sudamérica, Europa y África (SAGARHA, 2018). En respuesta a esta importancia del trigo cristalino y con base en las evaluaciones de rendimiento de grano llevado a en el Campo Experimental Norman E. Borlaug (CENEB), se propuso la liberación de la línea experimental de trigo duro CNDO/PRIMADUR//HAI-OU-17/3/SNITAN/4/JUPAREC2001/5/CNDO/PRIMADUR//HAIOU -17/3/SNITAN/6/RISSA/GAN//POHO-1/3/PLATA-3//CREX/ALLA*2/4/ARMENT//SRN-3/ NIGRIS-4/3/CANELO-9.1, como nueva variedad denominada “CENEB Oro C2017”.

Population data for 21 autosomal STR loci (GlobalFiler kit) in two Mexican-Mestizo population from the northwest, Mexico.

Mexican Mestizos (admixed) have been poorly studied for short tandem repeats (STRs) included for new human identification (HID) kits, such as the GlobalFiler PCR Amplification kit. Therefore, this kit was analyzed in 784 unrelated volunteers from the city of Tijuana (n = 381) and Sonora state (n = 403) in the northwest region of Mexico. Allele frequencies, forensic parameters, Hardy-Weinberg equilibrium, and linkage equilibrium were estimated or evaluated for 21 autosomal STRs, respectively. For this HID kit, the combined power of discrimination (PD) was > 0.99999999999999 (RMP range = 1.23 to 3.0 × 10-25), and the combined power of exclusion (PE) were 0.999999993 and 0.999999997 in Tijuana city and Sonora state, respectively. Interpopulation analyses based on STRs of the GlobalFiler kit was performed, including four Mexican Native American, one Mexican Mestizo, and four ethnic American populations (USA), previously studied. The low-but significant-differentiation observed among Mexican Mestizos (FST = 0.0969%; p = 0.02584) justifies the creation of STR databases for HID purposes in this country. In brief, results allow the confident use of the GlobalFiler kit for HID purposes in Mestizo population from the Northwest region Mexico.
