Objective: To know the prevalence of N. gonorrhoeae and C. trachomatis among women 18-30 years of age from the Autonomous University of Juárez, Mexico. Methodology: A cross sectional, observational study was done; the molecular diagnosis C. trachomatis and N. gonorrhoeae was done using the PCR proposed by Wong and Ho.; the culture of N. gonorrhoeae was on agar chocolate. Results. The sample included 216 women; the total number of sexual partners range from one to 37; 29% have had ≥4 partners; 23% of the women did not have protection in their last sexual intercourse. We found a prevalence of C. trachomatis of 6% and 2.3% for N. gonorrhoeae. We found that the infected women were younger, used less protection and none had history of pregnancy, but the differences were not significant. VOLUMEN. XII,.

  • Socioeconomic Inequalities Among the Municipalities of Chihuahua, Mexico
    T h e J o u r n a l o f D e v e l o p i n g A r e a s Volume 55 No. 3 Summer 2021 SOCIOECONOMIC INEQUALITIES AMONG THE MUNICIPALITIES OF CHIHUAHUA, MEXICO Omolara Adebimpe Adekanbi Isaac Sánchez-Juárez Both affiliated with Universidad Autónoma de Ciudad Juárez, México ABSTRACT The objective of this paper is to analyze the nature of inequalities among the municipalities of Chihuahua State, Mexico and the factors that contribute to the disparity. The state of Chihuahua has a deep household inequality due to the nature of the inhabitants’ occupations and comprises a significant percentage of the people living in poverty in Mexico because of social deprivation and low income. Previous studies on inequality in Mexico show that significant differences among the municipalities is caused by factors such as marginalization, low economic activity, and informal activities while some other studies have used similar variables selected from social and economic sphere. All these works used these variables to obtain the socioeconomic development index for each region under study. Following the methodology used in de Haro et al. (2017), this paper examines the social and economic conditions of the 67 municipalities of Chihuahua State by calculating the Socioeconomic Development Index (SEDI) of each municipality using the data compiled on variables such as marginalization, degree of urbanization, gross economic activity rate, economic dependence coefficient and density of paved roads. The result shows that two municipalities: Juarez and Chihuahua City have the most favorable socioeconomic conditions due to a high urban density and a low marginalization.

  • New Distributional and Temporal Bird Records from Chihuahua, Mexico
    Israel Moreno-Contreras et al. 272 Bull. B.O.C. 2016 136(4) New distributional and temporal bird records from Chihuahua, Mexico by Israel Moreno-Contreras, Fernando Mondaca, Jaime Robles-Morales, Manuel Jurado, Javier Cruz, Alonso Alvidrez & Jaime Robles-Carrillo Received 25 May 2016 Summary.—We present noteworthy records from Chihuahua, northern Mexico, including several first state occurrences (e.g. White Ibis Eudocimus albus, Red- shouldered Hawk Buteo lineatus) or species with very few previous state records (e.g. Tricoloured Heron Egretta tricolor, Baltimore Oriole Icterus galbula). We also report the first Chihuahuan records of Red-tailed Hawk Buteo jamaicensis harlani and ‘White-winged’ Dark-eyed Junco Junco hyemalis aikeni (the latter only the second Mexican record). Other records improve our knowledge of the distribution of winter visitors to the Chihuahuan Desert ecoregion that formerly were considered transients, including several parulids. Our field work has also improved knowledge of the distribution of certain Near Threatened (e.g. Snowy Plover Charadrius nivosus) and Vulnerable species (e.g. Pinyon Jay Gymnorhinus cyanocephalus). We also confirmed various breeding localities for Yellow-crowned Night Heron Nyctanassa violacea in Chihuahua. The avian diversity of Mexico encompasses 95 families, 493 genera and 1,150 species following IOC taxonomy (cf. Navarro-Sigüenza et al. 2014) or c.11% of total avian richness worldwide. Mexico is ranked as the 11th most important country in terms of bird species richness and fourth in the proportion of endemic species (Navarro-Sigüenza et al. 2014). However, Chihuahua—the largest Mexican state—is poorly surveyed ornithologically, mostly at sites in and around the Sierra Madre Occidental (e.g., Stager 1954, Miller et al.

Dissertation Presented to the Faculty of the Graduate School of the University of Texas at Austin in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy The University of Texas at Austin May 2007 Acknowledgements While there are many people deserving of recognition for their assistance and support during the process of completing this research, I can mention here only a few. First, without a doubt, I would like to thank Irene for her love and support over the years, and without whom this process might never have started, and certainly would not have ended. I thank my mother, Marilyn Chumley, for her love and support as well, especially after the death of my father, Don Chumley; I trust that he would be proud of this accomplishment. My advisor, Dr. Robert K. Jansen and my cohort of labmates deserve mention for providing a fun and challenging environment. Jan Barber, Romey Haberle, Barbara Goodson, and Micheal J. Moore all provided excellent advice, discussion or feedback in the lab or field. Everyone who went into the field with me needs a special award, particularly if the Land Cruiser decided to break down on that particular trip; Geoff Denny gets kudos for the Monterrey experience, when we, like an old submarine, ran only on batteries, and Mike gets some kudos for the Deerslayer episode, and the many, many beers and many, many miles, usually not at the same time of course.

INFORMATION TO USERS The most advanced technology has been used to photo­ graph and reproduce this manuscript from the microfilm master. UMI films the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer. The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction.
