Authors: Pertuz Belloso Rafael 
Published: December 2019

Recibido 13 de enero de 2013 • Corregido 18 de marzo de 2013 • Aceptado 11 de setiembre de 2013La presente investigación tuvo como objetivo proponer un modelo de estructura organizacional para los institutos universitarios, vinculante con la realidad socio económica venezolana. El estudio corresponde a una investigación de campo de carácter descriptiva, con un diseño no experimental trasversal. La población del estudio estuvo constituida por un conjunto de 746 profesores y directivos de los institutos tecnológicos de Cabimas y Maracaibo. La técnica de recolección empleada fue la encuesta con un cuestionario compuesto por 54 ítems. La técnica de análisis de los datos fue la distribución de frecuencias porcentuales. Los resultados obtenidos indican qué subsistemas no se encuentran integrados en las instituciones estudiadas, así como la coexistencia de tipologías estructurales burocráticas, además de una clara descontextualización en la aplicación de los planes de la nación, lo cual evidencia escasa pertinencia y vinculación con la realidad socio económica venezolana. Para solucionar esta realidad, se diseñó un modelo de estructura organizacional mixto departamental/matricial que integra el departamento en una red matricial que vincula la docencia, la investigación y la extensión. Para la aplicación de este modelo se propuso su instrumentación en tres etapas o fases que permitirán alcanzar las características operativas del modelo departamental.

Clinical Value of lncRNA LUCAT1 Expression in Liver Cancer and its Potential Pathways
Authors: Jiao Yan , Li Yanqing , Ji Bai , Cai Hongqiao , Liu Yahui 
Published: December 2019

Background and Aims: Emerging studies indicate that long noncoding RNAs (lncRNAs) play a role as prognostic markers in many cancers, including liver cancer. Here, we focused on the lncRNA lung cancer-associated transcript 1 (LUCAT1) for liver cancer prognosis.
Methods: RNA-seq and phenotype data were downloaded from the Cancer Genome Atlas (TCGA). Chisquare tests were used to evaluate the correlations between LUCAT1 expression and clinical features. Survival analysis and Cox regression analysis were used to compare different LUCAT1 expression groups (optimal cutoff value determined by ROC). The log-rank test was used to calculate the p-value of the Kaplan-Meier curves. A ROC curve was used to evaluate the diagnostic value. Gene Set Enrichment Analysis (GSEA) was performed, and competing endogenous RNA (ceRNA) networks were constructed to explore the potential mechanism.
Results: Data mining of the TCGA -Liver Hepatocellular Carcinoma (LIHC) RNA-seq data of 371 patients showed the overexpression of LUCAT1 in cancerous tissue. High LUCAT1 expression was associated with age (p=0.007), histologic grade (p=0.009), T classification (p=0.022), and survival status (p=0.002). High LUCAT1 patients had a poorer overall survival and relapse-free survival than low LUCAT1 patients. Multivariate analysis identified LUCAT1 as an independent risk factor for poor survival. The ROC curve indicated modest diagnostic performance. GSEA revealed the related signaling pathways, and the ceRNA network uncovered the underlying mechanism.
Conclusion: High LUCAT1 expression is an independent prognostic factor for liver cancer.
Global Health Experience and Interest: Results From the AAP Periodic Survey
Authors: Chan Kevin , Sisk Blake , Yun Katherine , St Clair Nicole E. 
Published: December 2019

BACKGROUND:
Interest and participation in global health (GH) experiences have increased over the past 30 years in both medical schools and residencies, but little is known at the level of practicing pediatricians.

METHODS:
Data were compared from the American Academy of Pediatrics Periodic Surveys conducted in 1989 and 2017. The surveys had a response rate of 70.8% in 1989 and 46.7% in 2017. There were 638 and 668 postresidency pediatricians in the 1989 and 2017 surveys, respectively. Descriptive analyses were performed to look at changes in experience and interest in GH. A multivariable logistic regression was conducted specifically looking at characteristics associated with interest in participating in GH experiences in the next 3 years.

RESULTS:
Pediatrician participation in GH experiences increased from 2.2% in 1989 to 5.1% in 2017, with statistically significant increases in pediatricians ≥50 years of age. Interest in participating in future GH experiences increased from 25.2% in 1989 to 31.7% in 2017, with a particular preference for short-term clinical opportunities. In the multivariable logistic regression model, the year 2017 was associated with an increased interest in future GH experience, especially in medical school, hospital or clinic practice settings, as well as among subspecialists.

CONCLUSIONS:
Over the past 28 years, practicing pediatricians have increased their involvement in GH, and they are more interested in future GH experiences. The focus is on short-term opportunities. Our study reveals that practicing pediatricians mirror medical trainees in their growing interest and participation in GH.
The tradition of snake-thread glass in Pannonia
Authors: Dévai Kata 
Published: December 2019

Abstract
Snake-thread glass vessels were used from the late 2nd to the mid-3rd century AD. At least two production centres/distribution circles have been identified in the western part of the Roman Empire, which probably owed their existence to Syrian glassmaking artisans migrating to the west. One was located in the Rhine region, the other in Pannonia. Considering the distribution of snake-thread glass fragments known to date from Pannonia, it is striking that 52 of the currently known 112 fragments were found at Intercisa, 45 exemplars came to light at Brigetio and only a few pieces are known from other sites. It is remarkable that in both towns, glass workshops were active during the same period and there is also some evidence that snake-thread glass had been produced in the workshop of Brigetio.
Estudio dialectológico perceptual de las Antillas hispánicas
Authors: Sobrino Triana Roxana 
Published: December 2019

In this paper I analyzed the Spanish - speaking Caribbean´s dialectal perceptions (Cubans, Puerto Ricans and Dominicans), in order to know the mental delimitation of the linguistic area to which their varieties are circumscribed, the elements through which they distinguish it and the way in which they perceived themselves linguistically in the Spanish-speaking context in general. The analysis has been based on the postulates of Perceptual Dialectology. From the methodological point of view, a questionnaire was applied in the capitals of the three countries in which four questions addressed the linguistic perceptions. The sample was formed from a fixed quota sampling, for a total of 198 informants surveyed in the three countries, of which the variables sex, age and level of education were controlled.
Some of the most important concluding ideas of the study are that the Antillean perceive their varieties of Spanish as inserted in a common dialectal space, although with variable limits. In a triangle of relationships, Puerto Ricans and Cubans perceive their respective varieties of Spanish as much closer and more like each other than to the Spanish in the Dominican Republic. Dominicans, on the other hand, show a weaker awareness of the link between the three varieties. As for the differentiating perceptions, is evident a perceptual distance from other variants (such as the Spanish, Colombian, Mexican and Argentine), based on arguments that show the prestige granted to these modalities of language.
Narcomenudeo y control territorial en América Latina
Authors: Saborío Sebastián 
Published: December 2019

El presente artículo analiza el fenómeno del control territorial llevado a cabo por parte de grupos criminales que se dedican al narcomenudeo en barrios de las ciudades latinoamericanas. Demuestra que las publicaciones sobre el tema asumen que existe una definición clara de “control territorial”, pero terminan por referirse a procesos sociales diferentes. Apoyándose en los conceptos de territorio, territorialidad y territorialización, el autor define los elementos que conforman las diferentes modalidades de control territorial que llevan a cabo las bandas del narcomenudeo. De esa manera, brinda una herramienta de análisis compuesta por diferentes indicadores: quiénes son los sujetos controlados por las bandas, cuál es la extensión, modalidad y objetivos del control territorial y de qué manera dichos grupos influencian la vida política, asociativa y otras esferas de la cotidianeidad de las comunidades en las cuales están situados.
Abstract
This article analyses the phenomena of territorial control that is carried on by small scale drug trafficking groups in Latin American cities. It shows that existing publications on this topic take for granted what “territorial control” is, but end up referring to different social processes. Leaning in the concepts of territory, territoriality and territorialization, the author defines which elements shape the different modalities of territorial control implemented by small scale drug trafficking groups. In this way, he provides an analytical tool composed by different indicators: who are the subjects controlled by drug gangs, what is the extension, modality and objectives of territorial control and how do these groups influence political and associative life as well as other spheres of everyday life of the communities in which they are located.
Hechos ciberfísicos: una propuesta de análisis para ciberamenazas en las Estrategias Nacionales de Ciberseguridad
Authors: Aguilar-Antonio Juan-Manuel 
Published: December 2019

El artículo presenta la categoría de hechos ciberfísicos, una propuesta para el análisis y la delimitación de amenazas en el régimen híbrido del ciberespacio. Se propone la hipótesis de que América Latina, y en particular México, no comprenden en sus Estrategias Nacionales de Ciberseguridad (ENCS) la naturaleza de las ciberagresiones ni la posibilidad de que una crisis surgida en el ciberespacio salte al espacio físico o material. Para probarla se presenta el contexto de la ciberseguridad en la región y se realiza una crítica de la ENCS de México. Después se hace un análisis comparativo de cinco casos de interés y referencia entre los estudios de ciberseguridad, para introducir el concepto de hecho ciberfísico. Por último, se aplica la propuesta a un estudio de caso y se muestra su utilidad para las ENCS, así como su grado de impacto en la esfera de la seguridad pública y nacional.
Abstract
The article introduces the category of cyber-physical facts, a proposal for the analysis and delimitation of threats in the hybrid regime of cyberspace. The research objective is to test the hypothesis that Latin America, and Mexico in particular, do not understand in their National Cybersecurity Strategies (NCSS) the nature of cyber-attacks, nor the possibility that a crisis arising in cyberspace will jump into the physical or material ground. To prove this, the context of cybersecurity in the region is presented and also a critique of the NCSS of Mexico. Then, the article makes a comparative analysis of five cases of interest and reference in cybersecurity studies to introduce the concept of cyber-physical fact. Finally, this proposal is applied to a case study, and its usefulness to the NCSS is shown, as well as its degree of impact in the sphere of public and national security.
Neotectonic and Paleoseismic Analysis of the Northwest Extent of Holocene Surface Deformation along the Meers Fault, Oklahoma

Published: December 2019

ABSTRACTThe Meers fault (Oklahoma) is one of few seismogenic structures with evidence for Holocene surface rupture in the stable continental region of North America. The 37-kilometer-long southeast section of the full 54-kilometer-long Meers fault is interpreted to be Holocene active. The 17-kilometer-long northwest section is considered Quaternary active, but not Holocene active. We reevaluate surface expression and earthquake timing of the northwest Meers fault to improve seismic source characterization. We use airborne light detection and ranging and historical stereopaired aerial photos to evaluate the fault scarp and local fault-zone geomorphology. In the northwest, complex surface deformation includes fault splays, subtle monoclinal warping, and a minor change in fault strike. We interpret that the along-strike transition from surface faulting on the southeast Meers fault to surface folding on the northwest Meers fault occurs at the lithologic contact between Permian Post Oak conglomerate and Hennessey shale. We excavated a paleoseismic trench to evaluate the timing of surface-deforming earthquakes on the northwest section of the fault. The excavation revealed weathered Permian Hennessey shale and an ∼1–2-meter-thick veneer of Holocene alluvial deposits that were progressively deformed during two surface-folding earthquakes likely related to blind fault rupture beneath the site. Repeated onlapping to overlapping stratigraphic sequences and associated unconformities are intimately related to folding events along the monocline. OxCal paleoearthquake age modeling indicates that earthquakes occurred 4704–3109 yr B.P. and 5955–4744 yr B.P., and that part of the northwest section of the Meers fault is Holocene active. We find the Holocene-active section of the Meers fault should be lengthened 6.1 km to the northwest, to a total Holocene-active fault length of 43 km. Empirical scaling relationships between surface rupture length and magnitude reveal that the fault could generate an Mw 7.0 earthquake.
Brain Remain
Authors: Lieberman Devorah , Capaldi Shannon 
Published: December 2019

Volumes of research studies, surveys, and census data document the “brain drain,” the phenomenon of highly educated and highly skilled workers migrating from their hometown to an urban or metropolitan area that promises a better life. Early indications of brain drain begin with high school graduates determining where to attend college. There is a pervasive belief that it is a measure of success and part of a process of upward mobility to go away to college, and therefore an implied failure if one remains in their hometown or region while earning a degree. This mentality and encouraged brain drain behavior is reinforced by a K-12 education system that sorts students early in their academic careers and invests in the best and brightest, while paying little attention to the majority of students (Harmon, 2010). This is a skewed approach and leaves many individuals, and their hometowns, with few opportunities and stifled upward social and economic mobility.

The needs of the workforce are rapidly changing. Some form of post-secondary education is required for the majority of entry-level jobs in the United States (Bureau of Labor Statistics, 2017). Yet, higher education is being faced with increasing competition and growing skepticism regarding the value of a college degree. By collaborating and partnering with the region in which an institution exists, urban, suburban, or rural, colleges and universities can cut through higher education’s competitive noise and growing skepticism, while addressing the changing workforce needs and redefining students’ pride about where they earn a degree, and begin their careers, close to home.
We call this paradigm shift the “Brain Remain,” and it has the potential to significantly alter the way higher education, K-12 districts, businesses, and community leaders work, operate, and collaborate in the new economy. This, in turn, can create bold new opportunities for students where they least expect them: right in their own backyards.
¡Eh, tú! ¿Por qué me traduces con eco? La traducción del multilingüismo para el soporte unimodal y multimodal de la obra "Coco"
Authors: Hurtado Malillos Lorena , Cuéllar Lázaro Carmen 
Published: December 2019

En la literatura latina o literatura de origen hispano desarrollada en los Estados Unidos, es frecuente el uso de la L3 o segunda lengua español en el texto y la alternancia de código entre este idioma y la lengua base inglés en el desarrollo de la escritura. Debido a esta particularidad, traducir una obra de estas características a otra lengua puede suponer un gran desafío para el traductor. El propósito de este artículo es determinar en qué modo influyen los factores soporte y receptor en el tipo de técnicas de traducción elegidas para llevar a cabo la transferencia de estos términos en L3. Para ello, se han comparado dos obras translingües con distinto tipo de receptor, la adaptación textual de la película Coco con receptor infantil y la novela In the Time of the Butterflies con receptor adulto y a su vez, dos obras con distinto tipo de soporte, una obra unimodal, de nuevo, la adaptación textual de la película Coco y una obra multimodal, la propia obra audiovisual. Palabras clave: multilingüismo, translingüismo, L3, soporte, receptor, literatura infantil y juvenil, Coco

Este artigo discute o fenômeno de power creepno card gamedigital Hearthstone(Blizzard, 2012), problematizando-o a partir das perspectivas da midiatização, serialização e capitalismo tardio. O objetivo central é politizar a questão, apontando para os imbricamentos da indústria cultural contemporânea com as perspectivas epistemológicas e ontológicas do jogo enquanto chave interpretativa. Nesse sentido, empreendemos o esforço de revisar algumas teorias da midiatização, observando em particular o conceito nos videogames a partir da serialização. Partimos para uma análise empírica exploratória de relatos de jogadores profissionais no Youtube, revelando discursos nos ajudam a localizar a agência do capitalismo tardio a partir da serialização e da midiatização. Por fim, reforçamos a necessidade de contemplar os pontos desvelados pela pesquisa na compreensão da indústria contemporânea do entretenimento, bem como a necessidade de (re)pensar os entendimentos particulares sobre jogos digitais e suas culturas.

Published: December 2019

TiO2-CaO and TiO2-CaO-Fe2O3 photocatalysts have been synthesized through the surfactant-assisted sol-gel method. The catalysts were characterized using XRD, FTIR, SEM-ED Sand BET surface area. XRD pattern showed the formation of anatase TiO2 crystal phase both in TiO2-CaO and TiO2-CaO-Fe2O3. The TiO2-CaO has higher crystallinity than TiO2-CaO-Fe2O3. Based on the peak refinement using Rietveld, there are two peaks identified as Fe2O3 hematite in the sample TiO2-CaO-Fe2O3. BET surface area analysis showed that the average pore size of TiO2-CaO and TiO2-CaO-Fe2O3 catalysts are 8.04 and 8.41 nm respectively, indicating both catalysts are mesoporous.FTIR spectra show that the vibration of Ti-O, Ca-O, and Ca-TiO2 were observed in both catalysts. SEM images confirm that both catalysts are porous material. The catechol removal using TiO2-CaO and TiO2-CaO-Fe2O3 improved with the increase of catalyst concentration. After 360 minutes of UV radiation, the removal of catechol using TiO2-CaO-Fe2O3 reached 46.0%, 48.3%, and 69.2%, while when using TiO2-CaO, it reached 22.1%, 36.8%, and 57.0% for 0.1 g, 0.15 g, and 0.2 g of catalysts, respectively. The photocatalytic activity of TiO2-CaO-Fe2O3 is not so strong compared to TiO2-CaO catalyst but the catechol adsorption property of TiO2-CaO-Fe2O3 is higher than that of TiO2-CaO catalyst.
