Iris: an Extensible Application for Building and Analyzing Spectral Energy Distributions

Iris is an extensible application that provides astronomers with a user-friendly interface capable of ingesting broad-band data from many different sources in order to build, explore, and model spectral energy distributions (SEDs). Iris takes advantage of the standards defined by the International Virtual Observatory Alliance, but hides the technicalities of such standards by implementing different layers of abstraction on top of them. Such intermediate layers provide hooks that users and developers can exploit in order to extend the capabilities provided by Iris. For instance, custom Python models can be combined in arbitrary ways with the Iris built-in models or with other custom functions. As such, Iris offers a platform for the development and integration of SED data, services, and applications, either from the user's system or from the web. In this paper we describe the built-in features provided by Iris for building and analyzing SEDs. We also explore in some detail the Iris framework and software development kit, showing how astronomers and software developers can plug their code into an integrated SED analysis environment.Comment: 18 pages, 8 figures, accepted for publication in Astronomy & Computin

archivist: An R Package for Managing, Recording and Restoring Data Analysis Results

Everything that exists in R is an object [Chambers2016]. This article examines what would be possible if we kept copies of all R objects that have ever been created. Not only objects but also their properties, meta-data, relations with other objects and information about context in which they were created. We introduce archivist, an R package designed to improve the management of results of data analysis. Key functionalities of this package include: (i) management of local and remote repositories which contain R objects and their meta-data (objects' properties and relations between them); (ii) archiving R objects to repositories; (iii) sharing and retrieving objects (and it's pedigree) by their unique hooks; (iv) searching for objects with specific properties or relations to other objects; (v) verification of object's identity and context of it's creation. The presented archivist package extends, in a combination with packages such as knitr and Sweave, the reproducible research paradigm by creating new ways to retrieve and validate previously calculated objects. These new features give a variety of opportunities such as: sharing R objects within reports or articles; adding hooks to R objects in table or figure captions; interactive exploration of object repositories; caching function calls with their results; retrieving object's pedigree (information about how the object was created); automated tracking of the performance of considered models, restoring R libraries to the state in which object was archived.Comment: Submitted to JSS in 2015, conditionally accepte

Follow-up study of over three years of patients with uveitis after cataract phacoemulsification: outcomes and complications

Purpose: To evaluate the rate and onset of intraoperative and postoperative complications post-phacoemulsification. Methods: One hundred sixty-two eyes of 145 patients with uveitis who underwent phacoemulsification between 2006 and 2009 were identified through surgical record review. Fifty-nine eyes of 46 patients met the inclusion criteria. Hazard ratio (HR) and Kaplan-Meier survival probability were calculated for each class of uveitis. Results: Macular edema (ME) resulted to be associated to chronic postoperative inflammation (r = 0.6; p = 0.00) and mostly related to patients who presented more than one postoperative relapse/year (r = 0.2; p = 0.02). Fuchs uveitis resulted to be a risk factor for posterior capsule opacification (PCO) (HR 3.36 IC95%1.0-10.5; p = 0.03). Hypotony and elevated intraocular pressure (IOP) were detected in the anterior uveitis group (0.02 EY). Conclusion: The HR to develop ME was significantly related to chronic anterior uveitis. PCO and elevated IOP are

Hyphessobrycon nicolasi (Teleostei: Characidae) a new species from the Uruguay River basin in the Mesopotamian Region, Argentina

Hyphessobrycon nicolasi is described from the Uruguay River basin in the Mesopotamian Region, Entre Ríos, Argentina. The new species can be distinguished from all congeners by the presence of a well-defined oblique and marginal black stripe on each lobe of the caudal fin. Other characters defining H. nicolasi are the possession of 1-3 teeth with 3-10 cusps on maxilla; outer premaxillary row with 2-3 small teeth, with 5 or 7 cusps; iv-vi, 27-36 anal-fin rays; 33-36 scales on the longitudinal series; two vertical dark spots on the humeral region; dorsal and anal fins dappled in black and base of caudal fin bearing conspicuous black spot; and the presence of bony hooks on the rays of dorsal, anal and caudal fins of the mature males.Fil: Miquelarena, Amalia Maria.

Name It and Claim It: Cross-Campus Collaborations for Community-Based Learning

This article describes the value of cross-campus collaborations for community-based learning. We argue that community-based learning both provides unique opportunities for breaking academic silos and invites campus partnerships to make ambitious projects possible. To illustrate, we describe a course Writing for Social Justice that involved created videos for our local YWCA\u27s Racial Justice Program. We begin by discussing the shared value of collaboration across writing studies and librarianship (our disciplinary orientations). We identify four forms of cross-campus collaboration, which engaged us in working with each other, with our community partner, and with other partners across campus. From there, we visualize a timeline, turning from the why of cross-campus collaborations to the how. Finally, we underscore the need to name and claim--to value and cultivate--cross-campus collaborations for community-based learning

Iris Marion Young. Responsabilidad social y solidaridad

Este artículo propone suplementar el modelo de Young de la responsabilidad como conexión social con la propuesta de la justicia como solidaridad. No se apela a una solidaridad meramente cosmopolita y abstracta, sino a una identificada con redes de ayuda y cooperación transnacionales que han surgido frente a las agresiones de la globalización neoliberal a los más empobrecidos, especialmente a las mujeres de clase humilde que afrontan los retos de la feminización de la pobreza y de la supervivencia. Se atiende a la interseccionalidad de las opresiones para dar base a la solidaridad feminista. Y, finalmente, se propone a la economía solidaria emergente -especialmente nos brinda ejemplos de Latinoamérica y de lazos políticos con iniciativas estadounidenses ligadas al comercio justo y a la colaboración transnacional- como fundamentos de la solidaridad global.This article aims at supplementing Young's model of responsibility as social linkage with that of Justice as Solidarity. We move beyond a discussion of solidarity as a mere cosmopolitan and abstract concept. Solidarity applies somehow to a number of assistance networks and transnational cooperation that have emerged to confront neoliberal, globalised aggressions to the poor, mostly to poor women challenging the feminization of poverty and survival. We resort to the the so-called Oppressions' Intersectionality to contextualize feminist Solidarity. Finally, we discuss the growing strength of Solidarity Economy to become the basis of global solidarity, specially after successful experiences in Latin America and various North-American initiatives concerning fair trade and transnational collaboration

Transformative Education in a Broken World: Feminist and Jesuit Pedagogy on the Importance of Context

This chapter relates the concept of positionality from feminist theory and pedagogy to the Ignatian paradigm to show how its focus on the individual, at the expense of the structural, fails to acknowledge the unequal power relationships that disadvantage students from minority groups. Focusing on the positionality of gay and lesbian students in the author\u27s classroom at a Jesuit college, it explores how becoming attentive to our own positions with respect to our students allows us better to examine how relationships of domination and subordination between members of oppressed and privileged groups in larger social and ecclesial contexts are re-created at the micro-level in the classroom
