Futuro y evidencialidad

El futuro es un tiempo verbal problemático en muchas lenguas, entre las que se cuenta el español. Los problemas principales son los siguientes: 1) el tiempo futuro puede recibir un elevado número de usos y valores; 2) de estas diferentes lecturas, algunas no expresan referencia temporal futura y, además, este empleo es, con diferencia, el más frecuente; y 3) la referencia temporal futura suele expresarse preferentemente por medio de otros tiempos y otras perífrasis verbales. Los intentos de caracterización del significado básico del futuro en términos temporales y/o modales no parecen poder tratar estas dificultades de manera satisfactoria. El propósito de este trabajo es presentar un nuevo enfoque unificado de la semántica del futuro en español basado en la noción de evidencialidad. Trataré de demostrar que, cuando el futuro se analiza como la expresión de un contenido evidencial -en particular, como una indicación de que la única fuente del contenido comunicado es una inferencia del hablante-, no solo puede caracterizarse fácilmente toda la variedad de usos y valores, sino que la concurrencia de otras formas para expresar la futuridad también encaja de manera natural en la propuesta.Future tenses are cross-linguistically problematic for various reasons: 1) they usually get a large number of different interpretations; 2) some of these readings do not carry a future time reference and, moreover, these are, by far, the most frequent ones; and 3) future time reference is successfully expressed by means of other tenses and verbal periphrases. Approaches to the meaning of the future in temporal and modal terms do not seem to be able to tackle these difficulties in an adequate way. The aim of this paper is to put forward a unified proposal for the meaning of the future in Spanish based on the notion of evidentiality. I will argue that, when the future is analysed as conveying an evidential meaning -more precisely, that the propositional content has as the only source-, the whole range of uses and interpretations can be easily accounted for, and the co-occurrence of other expressions to indicate futurity can also be accommodated within my proposal in a natural way

Generalized Linear Models for Geometrical Current predictors. An application to predict garment fit

The aim of this paper is to model an ordinal response variable in terms of vector-valued functional data included on a vector-valued RKHS. In particular, we focus on the vector-valued RKHS obtained when a geometrical object (body) is characterized by a current and on the ordinal regression model. A common way to solve this problem in functional data analysis is to express the data in the orthonormal basis given by decomposition of the covariance operator. But our data present very important differences with respect to the usual functional data setting. On the one hand, they are vector-valued functions, and on the other, they are functions in an RKHS with a previously defined norm. We propose to use three different bases: the orthonormal basis given by the kernel that defines the RKHS, a basis obtained from decomposition of the integral operator defined using the covariance function, and a third basis that combines the previous two. The three approaches are compared and applied to an interesting problem: building a model to predict the fit of children’s garment sizes, based on a 3D database of the Spanish child population. Our proposal has been compared with alternative methods that explore the performance of other classifiers (Suppport Vector Machine and k-NN), and with the result of applying the classification method proposed in this work, from different characterizations of the objects (landmarks and multivariate anthropometric measurements instead of currents), obtaining in all these cases worst results

Traditional Instruction Versus Virtual Reality Simulation: A Comparative Study of Phlebotomy Training among Nursing Students in Kuwait

This quasi-experimental study compared differences in phlebotomy performance on a live client, between a control group taught through the traditional method and an experimental group using virtual reality simulation. The study showed both groups had performed successfully, using the following metrics: number of reinsertions, pain factor, hematoma status, duration of tourniquet application, time to complete the procedure, and successful completion of procedure. Utilizing t-test in comparing the control and experimental groups, no performance metric was found to be significant. Total time to complete the procedure for both groups had the lowest p value, but was of no significance. Both methods for phlebotomy training were found to be equally effective. Nurse educators are challenged  to recognize the advantages and limitations of both methods to pave their way in an enhanced quality phlebotomy program. Keywords: Traditional method, Virtual reality simulation, Phlebotomy, Performance metrics

Identification and detection of iha subtypes in LEE-negative Shiga toxin-producing Escherichia coli (STEC) strains isolated from humans, cattle and food

LEE-negative Shiga toxin-producing Escherichia coli (STEC) strains are important cause of infection in humans and they should be included in the public health surveillance systems. Some isolates have been associated with haemolytic uremic syndrome (HUS) but the mechanisms of pathogenicity are is a field continuos broadening of knowledge. The IrgA homologue adhesin (Iha), encoded by iha, is an adherence-conferring protein and also a siderophore receptor distributed among LEE-negative STEC strains. This study reports the presence of different subtypes of iha in LEE-negative STEC strains. We used genomic analyses to design PCR assays for detecting each of the different iha subtypes and also, all the subtypes simultaneously. LEE-negative STEC strains were designed and different localizations of this gene in STEC subgroups were examinated.Genomic analysis detected iha in a high percentage of LEE-negative STEC strains. These strains generally carried iha sequences similar to those harbored by the Locus of Adhesion and Autoaggregation (LAA) or by the plasmid pO113. Besides, almost half of the strains carried both subtypes. Similar results were observed by PCR, detecting iha LAA in 87% of the strains (117/135) and iha pO113 in 32% of strains (43/135). Thus, we designed PCR assays that allow rapid detection of iha subtypes harbored by LEE-negative strains. These results highlight the need to investigate the individual and orchestrated role of virulence genes that determine the STEC capacity of causing serious disease, which would allow for identification of target candidates to develop therapies against HUS.Fil: Colello, Rocío.

Archetypal analysis with missing data: see all samples by looking at a few based on extreme profiles

In this paper we propose several methodologies for handling missing or incomplete data in Archetype analysis (AA) and Archetypoid analysis (ADA). AA seeks to find archetypes, which are convex combinations of data points, and to approximate the samples as mixtures of those archetypes. In ADA, the representative archetypal data belong to the sample, i.e. they are actual data points. With the proposed procedures, missing data are not discarded or previously filled by imputation and the theoretical properties regarding location of archetypes are guaranteed, unlike the previous approaches. The new procedures adapt the AA algorithm either by considering the missing values in the computation of the solution or by skipping them. In the first case, the solutions of previous approaches are modified in order to fulfill the theory and a new procedure is proposed, where the missing values are updated by the fitted values. In this second case, the procedure is based on the estimation of dissimilarities between samples and the projection of these dissimilarities in a new space, where AA or ADA is applied, and those results are used to provide a solution in the original space. A comparative analysis is carried out in a simulation study, with favorable results. The methodology is also applied to two real data sets: a well-known climate data set and a global development data set. We illustrate how these unsupervised methodologies allow complex data to be understood, even by non-experts

Social support and self care in diabetes type 2

Se realizó un estudio descriptivo y transversal con el objetivo de identificar la relación entre el ámbito laboral y familiar con las prácticas de autoatención y autocuidado de pacientes con diagnóstico de diabetes tipo 2, que concurren a los consultorios externos de diabetología de hospitales públicos dependientes del Gobierno de la Ciudad de Buenos Aires. Se tomó una muestra probabilística al azar sistemático de 337 pacientes entre 40 y 79 años que fueron encuestados con los siguientes instrumentos: cuestionario de datos personales y laborales, escala de frecuencias sobre prácticas de autoatención y autocuidado, ambos construidos ad hoc y validados previamente. Los datos fueron analizados estadísticamente con análisis descriptivos y pruebas bivariadas, según el nivel de medición de las variables. Los hallazgos del presente estudio evidencian que el apoyo social favorece una mayor adherencia a los tratamientos a través del cumplimiento de pautas de autocuidado.A descriptive and transversal study was made with the aim of identifying the relationship between the working and the family environment with the self attention and self care of patients with diabetes type 2 who are treated in Public Hospitals of Buenos Aires. A systematic sample of 337 people was randomly chosen. These people, aged since 40 to79 years old, had to answer the following: a questionnaire about personal and working issues, a frequency scale about self care and self attentions' practices, all of them built ad hoc and previously val idated. Data was analyzed statistically with descriptive and bivariated tests. According to the breakthroughs, social support helps the compliance to treatments through the fulillment of the self care prescriptions.Fil: Azzollini, Susana Celeste.

Archetypal shapes based on landmarks and extension to handle missing data

Archetype and archetypoid analysis are extended to shapes. The objective is to find representative shapes. Archetypal shapes are pure (extreme) shapes. We focus on the case where the shape of an object is represented by a configuration matrix of landmarks. As shape space is not a vectorial space, we work in the tangent space, the linearized space about the mean shape. Then, each observation is approximated by a convex combination of actual observations (archetypoids) or archetypes, which are a convex combination of observations in the data set. These tools can contribute to the understanding of shapes, as in the usual multivariate case, since they lie somewhere between clustering and matrix factorization methods. A new simplex visualization tool is also proposed to provide a picture of the archetypal analysis results. We also propose new algorithms for performing archetypal analysis with missing data and its extension to incomplete shapes. A well-known data set is used to illustrate the methodologies developed. The proposed methodology is applied to an apparel design problem in children
