Refactorización Orientada a Aspectos de Aplicaciones Empresariales

La importancia de las aplicaciones empresariales en las organizaciones de hoy en día, hace que sea necesario facilitar su mantenimiento y evolución a lo largo de su existencia. Este tipo de aplicaciones de gran complejidad cuentan con diversas funcionalidades y requerimientos que cortan transversalmente su estructura, para lo cual otros mecanismos de mo dularización más allá de la orientación a objetos resultarían convenientes. Dado que muchas de las aplicaciones empresariales se implementan utilizando el framework Spring puede utilizarse el módulo de AOP que este provee para obtener una mejor separación de los concerns. Con este objetivo, en este trabajo se presentan dos casos de estudios en los cuales se refactorizan los crosscutting concerns de dos aplicaciones empresariales con el prop ósito de encapsularlos en asp ectos. Con el fin de simplificar la tarea de refactorizacion un conjunto de refactorings, inicialmente presentados para AspectJ fueron adaptados para ser utilizados con Spring/AOP.Sociedad Argentina de Informática e Investigación Operativ

Teaching during the COVID-19 Pandemic: sharing results and data obtained from the Ames Test

We present a resource for instructors that contains results and data sets from the Ames test. Our aim is to share the results we have collected in previous semesters with other instructors, so they will be able to “conduct” the Ames test without the need to set foot in a laboratory classroom. Instructors will be able to use our online resource to perform the test remotely, as a supplement to their laboratory classroom, or even under hybrid circumstances. The coronavirus disease 2019 (COVID-19) pandemic brought many changes, including the way we, as instructors, were able to carry out our educational curricula, since access to laboratory classrooms was not always possible. While COVID-19 restrictions are still in place, and thus access to laboratory classrooms is limited or null, instructors can use our online resource, without the need to set foot in a laboratory classroom. When COVID-19 restrictions are lifted and access to laboratory classrooms is permitted, instructors can follow the procedures we describe and compare their results with ours, which appear in Results and Discussion, or use our data sets as take-home assignments for their students. In addition to its use in detecting the potential mutagenicity of different samples, we have found the Ames test to be extremely useful for developing problem-solving skills by means of exercises like the ones included in this resource. Furthermore, the potential of this test as a starting point for problem-based learning is remarkable. Some suggestions for its use in active learning settings are provided

Releasing transitional justice from the technical asylum: judicial reform in Guatemala seen through techne and phronesis

The application of universal ideas to specific settings is a crucial aspect of transitional justice. Yet, that application awakens tensions between universal and local conceptions of justice. This article considers the judicial reform programme carried out in Guatemala after its internal conflict. I use Hans-Georg Gadamer's concepts of technē and phronēsis to assess the programme and to suggest an alternative. I argue that the reforms were underpinned by technē, which involves choosing the appropriate means to attain an end. This technical approach entailed a reliance on indicators and expertise that resulted in a self-defeating project, where the process (re)produced the phenomena it strove to eliminate: impunity and violence. As an alternative, I suggest a model that relies on phronēsis, which would establish a dialogical relationship between universal values and particular circumstances. It would be undertaken in three layers: one involving the universal and the local, another embracing the means and the end, and the last engaging legal institutions with an ideal justice

Los observatorios de medios como experiencias para el análisis de las representaciones mediáticas de la realidad fronteriza: Una mirada desde México y Argentina

Reconsultas tempranas al servicio de urgencias antes y después de un protocolo para la crisis asmática del adulto: estudio de cohorte retrospectivo

Objetivo: Comparar las reconsultas al servicio de urgencias (SU) por asma durante la semana posterior al alta y explorar los factores asociados antes y después de la implementación de un protocolo asistencial. Materiales y métodos: Se realizó un estudio de cohorte retrospectivo que incluyó las consultas por crisis asmática de adultos al SU de un hospital universitario en los períodos 2016-2018 (preprotocolo) y 2019-2020 (posprotocolo). Se utilizó un modelo de regresión logística multivariado y se reportaron odds ratios (OR) e intervalos de confianza al 95 % (IC95%). Se consideró significativo un valor p < 0,05. Resultados: Las reconsultas fueron 38 (31,40 %) para el período preprotocolo y 33 (26,61 %) para el período posprotocolo. En el modelo de regresión multivariable, no se encontraron diferencias en las reconsultas tempranas al comparar el período posprotocolo con el período preprotocolo (OR 0,68; IC95% 0,26-1,74; p=0,421). Los factores asociados a las reconsultas tempranas fueron la edad (OR: 1,02; IC95%:1,00-1,04; p=0,017), el sexo masculino (OR 0,21 IC95%: 0,08-0,59; p=0,003), y el haber tenido más de una consulta al SU en el último año (OR 6,19 IC95%: 2,48-15,46; p<0,001). Conclusión: Aunque las reconsultas tempranas no disminuyeron luego de la aplicación del protocolo, se identificaron la edad y el haber tenido más de una visita al SU por asma dentro del último año como factores de riesgo para las reconsultas dentro de la semana, mientras que el sexo masculino resultó ser un factor protector

Carbon Dioxide, Hydrographic, and Chemical Data Obtained During the R/V Sarmiento de Gamboa Cruise in the North Atlantic Ocean on CLIVAR Repeat Hydrography Section OVIDE-2016-BOCATS (June 17 - July 31, 2016)

This dataset compiles information obtained during the cruise BOCATS 2016This dataset gathers discrete measurements of CO2 (pH and alkalinity) and hydrographic variables (salinity, temperature, dissolved oxygen, nitrate, phosphate and silicate) obtained during the cruise BOCATS carried out along the OVIDE section from 17 June to 31 July 2016. pH was measured spectrophotometrically following the Clayton and Byrne (1993). This method consists on adding a dye solution to the seawater sample, so that the ratio between two absorbances at two different wavelengths is proportional to the sample pH. Alkalinity was measured using an automatic potentiometric titrator Titrando 809 Metrohm, with a Metrohm 6.0232.100 combination glass electrode and a Pt-1000 probe for temperature measurement following the methodology given by Pérez and Fraga (1987). Dissolved oxygen was analyzed following the widely applied Winkler method. Determinations of nitrate, phosphate and silicate were carried out following methods described by Hansen and Grassoff (1983) Salinity and Temperature were recorded with a CTD probeBOCATS (CTM2013-41048-P)N

Rapid shoaling of the Aragonite Saturation Horizon along the OVIDE (A25) line

1 poster.-- 2018 Ocean Sciences Meeting, 11-16 February, Portland, Oregon, USAFrom 2002 to 2016, a biennial transoceanic section from Portugal to Greenland (Ovide section/GO-SHIP-A25 line, Fig. 1) was performed as part of the CLIVAR and GOSHIP programs. The marine CO2 system parameters were measured to study their temporal variability due to natural and anthropogenic drivers. The rather deep Aragonite Saturation Horizon (ASH) in the Irminger Sea has been experiencing a very rapid shoaling mainly due to the rapid penetration of the anthropogenic CO2. From 1991 to 2016, the ASH shoaled 12-14 m year-1 for the intermediate waters in the Irminger Sea. The deep-convection events occurred during severe winters (1991-1994 and 2015-2106) fostered the fast addition of more acidified water into the deep layers of the North Atlantic. We calculated the increase in anthropogenic CO2 during the last two decades (2002-2016) and its concomitant decrease in the excess of calcium carbonate over the aragonite saturation levels. We found a reduction of about 1/3 in the transport of ion carbonate excess over the saturation levels with respect to the natural CO2 cycle for the period 2002-2016. The projection of these results to a future scenario where the atmospheric CO2 is 500±20 ppm indicates that the export of the aragonite saturated waters to the deep Atlantic associated with the thermohaline circulation would be reduced in nearly 2/3, which will have a negative impact in the deep habitats based in carbonate structuresPeer reviewe
