The New World had hardly begun to fire the imagination of the Old before the Sons of Saint Francis, filled with a burning desire to spread the faith in the unknown lands in fulfillment of the biblical injunction “Go ye into the whole world and teach all nations” began their ceaseless peregrinations across two continents, from distant Canada and the forbidding Northwest to Tierra del Fuego and Patagonia in South America. In our own United States, dotting the land from Georgia to San Francisco, we find today the imposing ruins of Spanish missions built by their loving hands, their fervent faith, and their unequaled zeal.

Purpose Universidad San Francisco de Quito, USFQ, completed an assessment study to understand its performance in sustainability in 2012. This study aims to recognize the limitations of applying a North American rating system considering relevant criteria to a South American university and to emphasize the importance and lack of benchmarks available in the region. Design/methodology/approach Methodology used for this study is based on the Sustainability Tracking Assessment Rating System (STARS) by AASHE. In December 2013, USFQ joined the Pilot Program that included publicly documenting efforts, sharing feedback and making suggestions for system improvements. Findings Data collected by USFQ in 2012 and 2013 illustrate how the status of USFQ as a non-residential, teaching university in Ecuador in a developing country had several challenges while using an evaluation system established for universities within a North American system. The limits of assessing sustainability in South America are associated to its geographical location, the number of students and staff that commute to University and the lack of environmental services and certifications available in Ecuador. There are applicability issues with the use of STARS without performance reports from regional peers that can guide the development of relevant benchmarks for future comparability. Originality/value Little research has been conducted in the assessment and tracking of sustainability within universities in South America. This paper is one of the first to address the applicability of a North American self-reporting tool to a South American university.

“The most noble and most faithful city of St. Francis of Quito”, capital of the republic of Ecuador and formerly capital of the Audiencia of the same name, was founded upon the ruins of the capital of Atahualpa by the Spanish conqueror, D. Sebastián de Belalcázar y Medrano, on December 6, 1534. On January 25, 1535, the noble Flemish Franciscan, Fray Jodoco Ricke de Marselaer, assisted by two other Franciscans, placed the first stone of the building which was to become the first Franciscan monastery in South America. As was the custom, the patron of the new building was the saint of the day. In this case, the feast of the day was the Conversion of St. Paul and by this name was the new friary known.

Clepsine modesta was described by Verrill (1872) based on specimens collected in the West River and Whitneyville Lake, New Haven County, Connecticut, USA. Consistent with Article 73.2.3 of the International Code of Zoological Nomenclature (Anonymous 1999), the Syntype specimens of C. modesta originated from two localities and thus the type locality encompasses all of the places of origin. Moore (1898) synonomized C. modesta with the European Helobdella stagnalis (Linnaeus 1758) based on similarities in morphology. Subsequently, all North American leeches with a nuchal scute were considered as H. stagnalis with the exception of Helobdella californica Kutschera 1988, known only from Stow Lake, Golden Gate Park, San Francisco, California, USA. In addition to Europe and North America, Helobdella stagnalis has been reported from South America, Africa, and Asia (Sawyer 1986).

Light microscopic immunohistochemistry based on the principle of capillary action staining is a widely used method to localize antigens. Capillary action immunostaining, however, has not been tested or applied to detect antigens at the ultrastructural level. The aim of this work was to establish a capillary action staining method for localization of intracellular antigens, using colloidal gold probes.Post-embedding capillary action immunocytochemistry was used to detect maternal IgG in the small intestine of newborn suckling piglets. Pieces of the jejunum of newborn piglets suckled for 12 h were fixed and embedded into LR White resin. Sections on nickel grids were secured on a capillary action glass slide (100 μm wide capillary gap, Bio-Tek Solutions, Santa Barbara CA, distributed by CMS, Houston, TX) by double sided adhesive tape. Immunolabeling was performed by applying reagents over the grids using capillary action and removing reagents by blotting on filter paper. Reagents for capillary action staining were from Biomeda (Foster City, CA). The following steps were performed: 1) wet the surface of the sections with automation buffer twice, 5 min each; 2) block non-specific binding sites with tissue conditioner, 10 min; 3) apply first antibody (affinity-purified rabbit anti-porcine IgG, Sigma Chem. Co., St. Louis, MO), diluted in probe diluent, 1 hour; 4) wash with automation buffer three times, 5 min each; 5) apply gold probe (goat anti-rabbit IgG conjugated to 10 nm colloidal gold, Zymed Laboratories, South San Francisco, CA) diluted in probe diluent, 30 min; 6) wash with automation buffer three times, 5 min each; 7) post-fix with 5% glutaraldehyde in PBS for 10 min; 8) wash with PBS twice, 5 min each; 9) contrast with 1% OSO4 in PBS for 15 min; 10) wash with PBS followed by distilled water for5 min each; 11) stain with 2% uranyl acetate for 10 min; 12) stain with lead citrate for 2 min; 13) wash with distilled water three times, 1 min each. The glass slides were separated, and the grids were air-dried, then removed from the adhesive tape. The following controls were used to ensure the specificity of labeling: i) omission of the first antibody; ii) normal rabbit IgG in lieu of first antibody; iii) rabbit anti-porcine IgG absorbed with porcine IgG.
