Physical comparision and social physique anxiety: gender differences

La importancia de trabajar la autoestima y el desarrollo de una imagen corporal positiva se vislumbra con gran interés desde edades tempranas, debido a las consecuencias desadaptativas derivadas. El objetivo primario de este estudio fue analizar las posibles diferencias entre géneros en cuanto a la comparación hacia la apariencia física y la ansiedad física. Un segundo objetivo pretendió analizar la relación predictiva de la comparación hacia la apariencia física (hacia arriba y hacia abajo) sobre la ansiedad físico social. Participaron 347 universitarios (188 hombres y 159 mujeres) con edades entre 18 y 24 años (Medad = 20.42; DTedad = 1.54). Los resultados derivados de la prueba t de estudiante mostró diferencias estadísticamente significativas en comparación hacia arriba, comparación hacia abajo y ansiedad físico social a favor de la mujer. Los resultados emergidos del análisis de regresión lineal reflejaron que tanto la comparación hacia arriba como la comparación hacia abajo predijeron la ansiedad físico social, después de controlar el modelo por el género. Como conclusión, este estudio subraya que una excesivamente comparación hacia la apariencia física podría conducir a la ansiedad físico social tanto en hombres como en mujeres.The importance of working on self-esteem y the development of a positive body image is glimpsed with a great interest from an early age, due to the maladaptive consequences derived from them. The primary objective of this research was to analyze the possible difference among gender in appearance comparison y social physique anxiety.

Palatability of Alfalfa (\u3cem\u3eMedicago sativa\u3c/em\u3e L.) and Orchard Grass (\u3cem\u3eDactylis glomerata\u3c/em\u3e L.) Silages

The objective was to compare palatability with different methodologies for characterizing silages at Chapingo Autonomous University, México. Eight silages were used resulting from an experiment which evaluated effects of cutting time (08:00 and 14:00), time of wilting (0, 1 and 2 h) and use of lactic bacteria inoculant on properties of alfalfa (Medicago sativa L.) and orchard grass (Dactylis glomerata L.) silages. Organoleptic properties (odor, color, texture, moisture) were assessed by trained observers, using as categories: excellent, good, fair and poor. Dry matter content, CO2 rate of production and pH were also measured. For the evaluation of palatability with ewes, the experiment encompassed 18 days of adaptation and 14 days of measurement. In each of the 14 days of evaluation, four combinations of silages were evaluated (three silages per combination), each one assigned to experimental units formed by three ewes allotted by means of ratified random; each experimental unit was housed during 2.5 h in a pen with three feeders. The silages to be evaluated daily by each experimental unit were allotted randomly to these feeders. Silages harvested at 14:00 achieved highest scores in organoleptic, preference and intake evaluations. Results of preference and intake were similar and the results of PCA ordering of treatments resembled those of odor and texture and were opposite to those of pH and in a lesser extent also to those of aerobic deterioration. The organoleptic evaluation resulted an easy and cheap method to characterize silages, which results were reliable predictors of preference and intake (and hence quality) of alfalfa and orchard grass silages

On the performance of SQL scalable systems on Kubernetes: a comparative study

The popularization of Hadoop as the the-facto standard platform for data analytics in the context of Big Data applications has led to the upsurge of SQL-on-Hadoop systems, which provide scalable query execution engines allowing the use of SQL queries on data stored in HDFS. In this context, Kubernetes appears as the leading choice to simplify the deployment and scaling of containerized applications; however, there is a lack of studies about the performance of SQL-on-Hadoop systems deployed on Kubernetes, and this is the gap we intend to fill in this paper. We present an experimental study involving four representative SQL scalable platforms: Apache Drill, Apache Hive, Apache Spark SQL and Trino. Concretely, we analyze the performance of these systems when they are deployed on a Hadoop cluster with Kubernetes by using the TPC-H benchmark. The results of our study can help practitioners and users about what they can expect in terms of performance if they plan to use the advantages of Kubernetes to deploy applications using the analyzed SQL scalable platforms.Open Access funding provided thanks to the CRUE-CSIC agreement with Springer Nature.

Distributed Model-to-Model Transformation with ATL on MapReduce

International audienceEfficient processing of very large models is a key requirement for the adoption of Model-Driven Engineering (MDE) in some industrial contexts. One of the central operations in MDE is rule-based model transformation (MT). It is used to specify manipulation operations over structured data coming in the form of model graphs. However, being based on com-putationally expensive operations like subgraph isomorphism, MT tools are facing issues on both memory occupancy and execution time while dealing with the increasing model size and complexity. One way to overcome these issues is to exploit the wide availability of distributed clusters in the Cloud for the distributed execution of MT. In this paper, we propose an approach to automatically distribute the execution of model transformations written in a popular MT language, ATL, on top of a well-known distributed programming model, MapReduce. We show how the execution semantics of ATL can be aligned with the MapReduce computation model. We describe the extensions to the ATL transformation engine to enable distribution, and we experimentally demonstrate the scalability of this solution in a reverse-engineering scenario

La necesidad de medir la motivación situacional en el contexto español de la educación física: Psicometría de la Situational Motivation Scale

El objetivo primario de este trabajo fue comparar la estructura factorial de las diversas versiones propuestas (SIMS-16, SIMS-15, SIMS-14 y SIMS-13), así como de explorar la posible sostenibilidad de una nueva estructura para la Situational Motivation Scale (SIMS) en el contexto español de la Educación Física. El objetivo secundario fue aportar evidencias que respalden la invariancia factorial, consistencia interna y validez externa de la mejor estructura factorial identificada. Participaron 644 estudiantes (344 hombres y 300 mujeres; Medad = 15,04, DT = 1,58) de educación secundaria obligatoria y bachillerato en clase de EF. El análisis factorial confirmatorio no respaldó psicométricamente las diferentes versiones (SIMS-16, SIMS-15, SIMS-14 y SIMS-13) identificadas por la investigación previa para la SIMS. No obstante, los hallazgos sustentaron psicométricamente un modelo factorial de cuatro factores correlacionados y 12 ítems, que permaneció invariante respecto al género y nivel educativo. El análisis correlacional apoyó la validez discriminante del instrumento y, a su vez, respaldó el continuum de auto-determinación. El análisis de consistencia interna reflejó adecuados valores para cada factor. Los resultados del modelo de ecuaciones estructurales respaldaron los asertos del Modelo Jerárquico de Motivación Intrínseca/ Extrínseca. Como conclusión, se recomienda la utilización de una nueva estructura factorial para la Situational Motivation Scale (modelo de cuatro factores correlacionados y 12 ítems) para el alumnado de EF de secundaria obligatoria y bachillerato en el contexto español

Genomic prediction models for grain yield of spring bread wheat in diverse agro-ecological zones

Genomic and pedigree predictions for grain yield and agronomic traits were carried out using high density molecular data on a set of 803 spring wheat lines that were evaluated in 5 sites characterized by several environmental co-variables. Seven statistical models were tested using two random cross-validations schemes. Two other prediction problems were studied, namely predicting the lines’ performance at one site with another (pairwise-site) and at untested sites (leave-one-site-out). Grain yield ranged from 3.7 to 9.0 t ha−1 across sites. The best predictability was observed when genotypic and pedigree data were included in the models and their interaction with sites and the environmental co-variables. The leave-one-site-out increased average prediction accuracy over pairwise-site for all the traits, specifically from 0.27 to 0.36 for grain yield. Days to anthesis, maturity, and plant height predictions had high heritability and gave the highest accuracy for prediction models. Genomic and pedigree models coupled with environmental co-variables gave high prediction accuracy due to high genetic correlation between sites. This study provides an example of model prediction considering climate data along-with genomic and pedigree information. Such comprehensive models can be used to achieve rapid enhancement of wheat yield enhancement in current and future climate change scenario
