The spheroidal trackball: generalising the fixed trackball for virtual camera navigation

Virtual trackball techniques have become a standard in 3D applications, particularly for interfaces with limited degrees of freedom such as touchscreens or mice. The fact that we are used to them does not mean that they cannot be improved upon. Recent research has highlighted the significance of considering users’ mental models of a preferred rotation axis, as it can improve performance, perceived usability and perceived workload. Building upon these findings, this paper introduces the spheroidal trackball framework—a novel method for orbiting the virtual camera around elongated objects. The paper presents the mathematical formulation and the evaluation of the technique. The formulation offers enough information to implement the approach. The evaluation shows the advantages of this approach over the fixed spherical trackball for this class of objects, in terms of task performance, usability and perceived workload. This research constitutes an advancement in the refinement of 3D user interaction techniques, opening new avenues of innovation in this still evolving field.Funding for open access charge: Universidad Málaga/CBUA.

AnaPro, Tool for Identification and Resolution of Direct Anaphora in Spanish

Introduction Anaphora is a relation of coreference between linguistic terms. According to Webster’s dictionary: “It is the use of a grammatical substitute (as a pronoun or a pro-verb) to refer to the denotation of a preceding word or group of words; also : the relation between a grammatical substitute and its antecedent.” Therefore, anaphora is a discourse relation. Anaphora resolution is very important in Natural Language Processing (NLP). This work is part of Project OM* (Ontology Merging), which seeks to build a large ontology by fusing smaller ontologies extracted from textual documents. An important part of the project is to analyze the sentences in a document with the goal to transform that text into an ontology that comprises its contents. A brief description of Project OM* follows.AnaPro is software that solves direct anaphora in Spanish, specifically pronouns: it finds the noun or group of words to which the pronoun refers. It locates in the previous sentenc es the referent or antecedent which the pronoun replaces. An example of a direct anaphora solved is the pronoun “ he” in the sentence “He is sad.” Much of the work on anaphora has been done for texts in English; thus , we specifically focus on Spanish documents. AnaPro directly supports text analys is (to understand what a document says ), a non trivial task since there are different writing styles, references, idiomatic expressions, etc. The problem grows if t he analyzer is a computer, because they lack “common sense” (which persons possess) . Hence, before text analysis, its preprocessing is required, in order to assign tags (noun, verb,...) to each word, find the stems, disambiguate nouns, verbs, prepositions, identify colloquial expressions, i dentify and resolve anaphor a, among other chores. AnaPro works for Spanish sentences. It is a novel procedure, since it is automatic (no user intervenes during the resolution) and it does not need dictionaries. It employs heu ristics procedures to discover the semantics and help in the decisions; they are rather easy to implement and use li mited knowledge. Nevertheless, its results are good (81% of correct answers, at least). However, more tests will give a better idea of its goodness.Authors I.T. and E.V. would like to acknowledge ESCOM-IPN, where they defended their thesis, #20110083 , which gives a more detailed description of AnaPro.

Qualitative study on dialogic literary gatherings as co-creation intervention and its impact on psychological and social wellbeing in women during the COVID-19 lockdown

Background: Dialogic Literary Gatherings (DLG) are evidence-based interventions implemented in very diverse educational and health settings. The main elements that make DLG a co-creation intervention and promote health during the COVID-19 crisis lockdown are presented. This study focuses on the case of a DLG that is being promoted by an adult school in the city of Barcelona. Methods: This qualitative study was conducted using a communicative approach. Seven in-depth interviews with participants in the online DLG have been conducted. Five of them are women without higher education ranging from 56 to 85 years old and two are educators of this school. Results: The main results are 2-fold. First, the factors that make DLG a co-creation intervention, such as egalitarian dialogue and dialogical creation of knowledge in the decision-making process, are found. Second, the results show how DLG is contributing to creating a supportive environment that breaks the social isolation of confinement and improving the participants' psychological and social well-being. Conclusions: The findings from this study contribute to generating knowledge about a co-creation process between adult education participants and educators in education and health promotion during the COVID-19 lockdown, which could be replicated in other contexts

Postselection-Loophole-Free Bell Test Over an Installed Optical Fiber Network

Device-independent (DI) quantum communication will require a loophole-free violation of Bell inequalities. In typical scenarios where line-of-sight between the communicating parties is not available, it is convenient to use energy-time entangled photons due to intrinsic robustness while propagating over optical fibers. Here we show an energy-time Clauser-Horne-Shimony-Holt Bell inequality violation with two parties separated by 3.7 km over the deployed optical fiber network belonging to the University of Concepci\'on in Chile. Remarkably, this is the first Bell violation with spatially separated parties that is free of the post-selection loophole, which affected all previous in-field long-distance energy-time experiments. Our work takes a further step towards a fiber-based loophole-free Bell test, which is highly desired for secure quantum communication due to the widespread existing telecommunication infrastructure.Comment: 5 pages, 3 figures.

Esta investigación da a conocer la implementación de una línea de política social referida a los microcréditos, destinadas a emprendedoras de escasos recursos económicos, en la cual participan profesionales y estudiantes de Trabajo Social, en Misiones. Se analizan las estrategias y modos de organización que las emprendedoras utilizan para llevar adelante sus microemprendimientos y se busca dar a conocer cual es grado de intervención de los profesionales del trabajo social en la implementación de esta política social y cual es contribución a los procesos de ciudadanización de las mujeres. El proyecto se ejecutó en articulación con la ONG Desarrollo Humano Integral, que desarrolla proyectos de microcréditos, con Programas del Ministerio de Desarrollo Social de la Nación. Para la recolección de información, se tomaron como unidades de análisis a las mujeres beneficiarias de los microcréditos de los barrios “Prosol II” y “Medalla Milagrosa de Villa Cabello”. Como también a los Trabajadores Sociales responsables de la ejecución del proyecto. Se utiliza una metodología cualitativa, lo cual posibilita captar la percepción de las prestatarias en torno al microemprendimiento y la relación con su vida cotidiana. Para el aspecto cuantitativo se toma la información del banco de datos de la ONG

Histología uretral y vaginal en algunas hembras de mamíferos

El análisis de las características histológicas de la uretra y la vagina en hembras de mamíferos es útil para entender la fisiología y la patología de procesos como la continencia urinaria, la cópula y el parto. En este contexto, las especies más estudiadas en cuanto a la organización tisular de la uretra y vagina son la rata y la coneja. Es necesario estudiar con más detalle la organización tisular de la vagina y uretra en diferentes especies con fines de comparación. Tal información permitiría entender la diversidad funcional y conductual asociada a estos órganos. El presente documento reúne, compara y discute la información existente sobre las características histológicas de la uretra y la vagina en algunas hembras de mamíferos destacando aquellas de la coneja, modelo utilizado por nuestro grupo de investigación para estudiar la fisiología reproductiva y urinaria femenina
