Evaluation of Intangible Assets and Best Practices in a Medium-sized Port Community
AbstractThis paper analyses the main factors involved in the knowledge management of different actors participating in a Chilean port community. The intangible assets participating in the creation of value of the port community, which are expressed in ideas, attitudes, perceptions, experiences, information and knowledge management, are evaluated and classified according to community members’ core competencies. Then, the current situation of public institutions and companies participating in the port community is diagnosed utilizing interviews to experts and relevant actors. The role of the intellectual, structural, and social capital is examined in relation to strategic statements present in the missions of public and private port system companies. The results of the assessment enable to identify the main critical factors in knowledge management, transference, dissemination, collaboration and team work, storage, and best practices. In particular, the Conversation System stage of the Primary Model is analyzed and evaluated, as well as its causes, by actors of the port community and experts. Initiatives fostering collective work and encouraging conversations are proposed. Some of the best practices developed by the port community to create and disseminate stakeholders’ knowledge are presented. Also, a set of knowledge management indicators and indexes is developed and presented
Osmotic propulsion of colloidal particles via constant surface flux
We propose a model for the self-propulsion of a small motor particle that generates a nonuniform concentration distribution of solute in the surrounding fluid via a constant solute flux asymmetrically from the motor surface. The net osmotic driving force and motor speed are investigated in the limits of slow and fast product particle flux (relative to the diffusive flux of the product species). When the only solute species in solution is that produced by the motor, the motor's speed is shown to be proportional to the solute flux for slow flux rates and to the square root of the solute flux for large flux rates. When solute species are already present in solution at concentration high compared to that generated by the motor, the motor speed at high flux rates saturates and scales as the diffusivity of the solute divided by the motor size. The analytical results compare well with Brownian dynamics simulations. Full hydrodynamic interactions are taken into account in the theoretical analysis

Archeological Testing Associated with theStabilization of the Convento at Mission San Juan Capistrano (41BX5), San Antonio, Bexar County, Texas
In January and April, 2005, the Center for Archaeological Research (CAR) of The University of Texas at San Antonio conducted test excavations at Mission San Juan Capistrano (41BX5) for the San Antonio Missions National Historical Park of the National Park Service. The site is located approximately eight miles south of downtown San Antonio on the left bank of the San Antonio River.
The purpose of the excavations was to provide information on the nature and content of the subsurface deposits in preparation for a major stabilization campaign around the convento at Mission San Juan that will result in the installation of an impermeable barrier around the structure. Concrete footers will also be installed under each buttress, if necessary. Six 1-x-1-meter units were excavated around the convento and Rooms 19 and 21. Excavations conducted by CAR revealed disturbed deposits on the west side of the convento. A cut-stone step feature was encountered on the southeast side of the convento, along with a footer that was exposed near the northeast corner of the building. Excavations also revealed the original sandstone foundation of San Juan Capistrano on the south side of Room 21.
These investigations were conducted under Texas Antiquities Committee permit no. 3655 with Dr. Steve A. Tomka, CAR Director, serving as Principal Investigator. All cultural materials recovered and project-related documents are permanently curated at the Center for Archaeological Research

Physicochemical and sensory properties of yogurt as affected by the incorporation of jumbo squid (Dosidicus gigas) powder
The increase of soluble solids in milk by the addition of powdered products is a normal practice in the elaboration
of yogurt in order to enhance viscosity, texture and sensory properties for the consumer. The purpose of
this study was to evaluate the effect of adding jumbo squid (Dosidicus gigas) powder (protein content, 420 g/kg)
on the aforementioned quality properties of yogurt. Six formulations of yogurt were prepared with the addition
of 0, 1, 3, 5, 7 or 10 g/100 mL jumbo squid powder, plus one formulation with 3 g/100 mL maltodextrin. During
fermentation, yogurts formulated with squid powder gradually achieved greater viscosity while producing both
more acidity and at a higher rate than the controls. Apart from lower pH (hence, higher titratable acidity) and
higher viscosity, the final enriched yogurts presented lower syneresis than the controls (p < 0.05). Although the
highest viscosity (58.90 Pa.s) and the lowest syneresis (1.00%) was achieved by the yogurt with 10 g/100 mL
jumbo squid powder, it was the treatment formulated with 3 g/100 mL (pH 4.31, acidity 0.85 g/100 g, viscosity
40.90 Pa.s and syneresis 9.10%) that kept constant sensory properties, as evaluated by the panelists, while
improving some physical properties of the control yogurts.The authors are grateful to Biologist Armando Solari and the

Leaving the Devil You Know: Crime Victimization, US Deterrence Policy, and the Emigration Decision in Central America
Following a sharp increase in the number of border arrivals from the violence-torn countries of Guatemala, El Salvador, and Honduras in the spring and summer of 2014, the United States quickly implemented a strategy designed to prevent such surges by enhancing its detention and deportation efforts. In this article, we examine the emigration decision for citizens living in the high-crime contexts of northern Central America. First, through analysis of survey data across Guatemala, El Salvador, and Honduras, we explore the role crime victimization plays in leading residents of these countries to consider emigration. Next, using survey data collected across twelve municipalities in Honduras, we evaluate the extent to which knowledge of heightened US immigration deterrence efforts influenced respondents’ emigration decision. Though a vast majority of these respondents were aware of the stricter US immigration policy regime, this awareness had no effect on their consideration of emigration as a viable strategy
Habitat Characterization of Juvenile Atlantic Tarpon (Megalops atlanticus) in Isle of Youth, Cuba
Tarpon is considered a ‘Vulnerable’ species by IUCN but is also a highly prized recreational species. It is reportedly abundant in Cuba and may be threatened by high levels of fishing pressure. However, the current knowledge about Tarpon habitat characteristics and ecology in Cuba is very poor, which limit any attempt for its management and conservation. Here we summarize abiotic characteristics of juvenile Tarpon habitats in Lanier Swamp, Isle of Youth, Cuba, which is a RAMSAR site and Faunal Refuge. Three locations in Lanier Swamp were sampled for juvenile Tarpon presence during 2015-2017: Colony Lagoon (CL), Punta Francés Lagoon (PFL) and San Pedro (SP) river system. Abiotic characteristics were sampled from these same sites in January 2017. The smallest Tarpon (~150 mm fork length (FL, n= 22) occurred at CL, characterized by shallower waters with extreme salinities (0.6 and 50.8), less connection with the sea, and more protection from sunlight. In contrast, larger juvenile Tarpon (~630 mm FL, n= 20) were captured at SP, the location with the greatest connectivity to the ocean and greatest depth (~353 cm). The main results suggest that water depth, salinity, sunlight exposure and spatial dimensions are important habitat characteristics. Additionally, this study demonstrates the importance of coastal mangroves as juvenile Tarpon habitat and highlights the potential of using Tarpon as an umbrella species with broader conservation benefits. This study is an important first step to understanding Tarpon habitat use patterns in Cuba and developing a comprehensive conservation plan.
Resumen
El sábalo es considerado especie ‘Vulnerable’ según la UICN, pero también es altamente apreciado en la pesca recreativa. Se ha registrado como una especie abundante en Cuba y pudiera estar amenazado por altos niveles de presión pesquera. Sin embargo, el conocimiento actual sobre los hábitats y la ecología del sábalo en Cuba es escaso, lo cual limita cualquier intento de manejo y conservación. En este estudio se describen las características abióticas de hábitats de sábalos juveniles en la Ciénaga de Lanier, Isla de la Juventud, Cuba; área que es sitio RAMSAR y Refugio de Fauna. Tres localidades en la Ciénaga de Lanier fueron muestreados para juveniles por la presencia de sábalos juveniles durante 2015-2017: Laguna Colony (CL), Laguna Punta Francés (PFL) y sistema rivereño San Pedro (SP). Se tomaron muestras de las características abióticas de estos mismos sitios en enero de 2017. Los sábalos más pequeños (~150 mm de longitud horquilla (LH, n= 22) habitaron sitios en CL menos profundos, con salinidades extremas (0,6 and 50,8), menos conectados con el mar, y más protegidos de la luz solar. Los sábalos juveniles más grandes (~630 mm LH, n= 20) fueron capturados en SP, la localidad con mayor conectividad con el mar y mayor profundidad (~353 cm). Los resultados encontrados sugieren que la profundidad del agua, salinidad, exposición solar y dimensión espacial, son importantes características del hábitat. Adicionalmente, se demuestra la importancia de los manglares como hábitats de sábalos juveniles y se resalta el potencial de emplear al sábalo como especie sombrilla con amplios beneficios en la conservación. Este estudio es una importante contribución para entender los patrones de uso del hábitat de los sábalos en Cuba y desarrollar un plan de conservación integral
