Bilateral and Unilateral Asymmetries of Strength and Flexibility in Young Elite Sailors: Windsurfing, Optimist and Laser Classes

In sport sailing, performance is related to the sailor’s ability to maintain the stability of the boat, and the boat class determines the variables involved in such ability. In monohull-type vessels, such as the Optimist and Laser classes, the flexibility of the hip joint is a key performance factor. In the Windsurfing class, performance is determined by the strength of the flexors of the fingers and elbows. The performance of the sailor may be a ected by asymmetries in the strength and flexibility of the muscles and joints involved in technical actions. The objective of this study was to evaluate asymmetries in strength and flexibility in young sailors. Thirty-three young sailors (ten girls) from the Windsurfing, Optimist and Laser classes were assessed for manual strength and flexibility, by dynamometry and straight leg lift tests, respectively. The symmetry index and the functional asymmetry of compression force were calculated. The results showed no di erences between sailors according to gender. The sailors of the Laser class obtained the highest levels of manual strength, whereas those of the Windsurfing class showed the highest flexibility levels. The girls’ group andWindsurfing class had the highest percentage of sailors with strength asymmetry, whereas, the sailors of the Optimist class presented a greater percentage of asymmetry in flexibility. There were no di erences in upper limb strength and lower limb flexibility between the dominant and non-dominant sides

The controversy over the LFC: An analysis of the implications and viability of ELF ideology and the LFC.

Esta disertación cuestiona la ideología del inglés como lengua franca (English as a Lingua Franca, ELF) y la posible implementación del Lingua Franca Core (LFC) en nuestro contexto. El propósito de este análisis es evaluar la validez y la utilidad de estas ideas con el objetivo de dilucidar si sus propuestas se ajustan a las necesidades de los estudiantes del inglés como segunda lengua. La metodología de esta investigación se divide en dos partes principales. Primero, un trabajo teórico en el que se examinan las implicaciones del LFC para los investigadores, los profesores de inglés, y especialmente, los estudiantes. Y segundo, un estudio de actitudes y un estudio de percepción llevado a cabo en un grupo de estudiantes universitarios españoles. Los resultados obtenidos mostraron cierta prevalencia de la ideología del inglés como lengua franca (ELF) entre los estudiantes. Sin embargo, sus actitudes, la frecuencia de exposición, y sus aspiraciones, fueron factores determinantes que mostraron que tienen una mayor preferencia por los modelos estándares de pronunciación. Por lo tanto, el LFC no es todavía ni una opción viable ni un sustituto adecuado dentro del paradigma de la enseñanza del inglés.<br /

Challenges And Opportunities In Analytic-Predictive Environments Of Big Data And Natural Language Processing For Social Network Rating Systems

Social Media is playing a key role in today's society. Many of the events that are taking place in diverse human activities could be explained by the study of these data. Big Data is a relatively new parading in Computer Science that is gaining increasing interest by the scientific community. Big Data Predictive Analytics is a Big Data discipline that is mostly used to analyze what is in the huge amounts of data and then perform predictions based on such analysis using advanced mathematics and computing techniques. The study of Social Media Data involves disciplines like Natural Language Processing, by the integration of this area to academic studies, useful findings have been achieved. Social Network Rating Systems are online platforms that allow users to know about goods and services, the way in how users review and rate their experience is a field of evolving research. This paper presents a deep investigation in the state of the art of these areas to discover and analyze the current status of the research that has been developed so far by academics of diverse background

Cerambícidos xilófagos de encinas y alcornoques : estudio bioecológico y control de poblaciones

En este trabajo se profundiza en el conocimiento de los cerambícidos xilófagos presentes en encinares y alcornocales de la provincia de Huelva. Se consideran como principales especies perforadoras Cerambyx welensii y Prinobius germari. Destacan las diferencias de comportamiento encontradas entre ellas: la primera especie se muestra poco territorial y muy móvil, la segunda parece mostrar un comportamiento territorial y sedentario, al menos en lo que machos se refiere. Tras el análisis de diversas opciones para el control de poblaciones de insectos con hábitos semejantes, se propone una estrategia de Control Integrado que tenga como uno de sus pilares la atracción de estas especies para su captura, la repelencia o la confusión específica; es decir, el estudio aplicado de los compuestos semioquímicos. Palabras clave: xilófagos, Cerambyx, Prinobius, comportamiento, encina, alcornoque, manejo integrado.___________________________________The aim of this work is to present recent advances on the knowledge of holm oak and cork oak woodborers (Coleoptera: Cerambycidae) in Huelva (Andalussia, Spain). Cerambyx welensii and Prinobius germari are considered the main implicated species. We emphasize over the differences of behavior founded among them: the first species is little territorial and very movable, Prinobius seems to show a more territorial and sedentary behavior, specially the males. After the analysis of diverse options for population control of insects with similar habits, a strategy of Integrated Management is recommended, having as one of his pillars the attraction of these species for his capture and/or the specific repelence or confusion; that is to say, the applied study of semiochemicals compounds to integrated pest management. Key words: woodborers, Cerambyx, Prinobius, ehavior, holm oak, cork oak, Integrated Pest Management

Differential effects of paramomycin on ribosomes of Leishmania mexicana and Mammalian cells

Paromomycin, an aminoglycoside antibiotic having low mammalian cell toxicity, is one of the drugs currently used in the chemotherapy of cutaneous and visceral leishmaniasis. In order to understand the mode of action of this antibiotic at the molecular level, we have investigated the effects of paromomycin on protein synthesis in Leishmania and its mammalian hosts. We were able to demonstrate that in vivo protein synthesis in the promastigote stage of the parasite and its proliferation rate are markedly inhibited by paromomycin while being only slightly affected by other aminoglycoside antibiotics, such as streptomycin and neomycin B. Furthermore, both in vitro polypeptide synthesis induced by poly(U) as mRNA and accuracy of translation are significantly decreased by paromomycin in cell-free systems containing ribosomal particles of Leishmania promastigotes. Conversely, when ribosomes from mammalian cells are used instead of the protozoan particles, polyphenylalanine synthesis is only barely reduced by the antibiotic and the translation misreading remains almost unaltered. Surface plasmon resonance analysis of the interaction between paromomycin and protozoan or mammalian cell ribosomal RNAs shows a strong binding of antibiotic to the parasite ribosomal decoding site and practically no interaction with the mammalian cell counterpart. Our results indicating differential effects of paromomycin on the translation processes of the Leishmania parasite and its mammalian hosts can explain the therapeutic efficiency of this antibiotic as an antileishmaniasis agent.Fil: Fernández, Marisa Mariel.

Cosmological solutions with nonlinear bulk viscosity

A recently proposed nonlinear transport equation is used to model bulk viscous cosmologies that may be far from equilibrium, as happens during viscous fluid inflation or during reheating. The asymptotic stability of the de Sitter and Friedmann solutions is investigated. The former is stable for bulk viscosity index $q1$. New solutions are obtained in the weakly nonlinear regime for $q=1$. These solutions are singular and some of them represent a late-time inflationary era.Comment: 16 pages Latex (IOP style); to appear Class. Quantum Gra

Sub-Sync: automatic synchronization of subtitles in the broadcasting of true live programs in spanish

Individuals With Sensory Impairment (Hearing Or Visual) Encounter Serious Communication Barriers Within Society And The World Around Them. These Barriers Hinder The Communication Process And Make Access To Information An Obstacle They Must Overcome On A Daily Basis. In This Context, One Of The Most Common Complaints Made By The Television (Tv) Users With Sensory Impairment Is The Lack Of Synchronism Between Audio And Subtitles In Some Types Of Programs. In Addition, Synchronization Remains One Of The Most Significant Factors In Audience Perception Of Quality In Live-Originated Tv Subtitles For The Deaf And Hard Of Hearing. This Paper Introduces The Sub-Sync Framework Intended For Use In Automatic Synchronization Of Audio-Visual Contents And Subtitles, Taking Advantage Of Current Well-Known Techniques Used In Symbol Sequences Alignment. In This Particular Case, These Symbol Sequences Are The Subtitles Produced By The Broadcaster Subtitling System And The Word Flow Generated By An Automatic Speech Recognizing The Procedure. The Goal Of Sub-Sync Is To Address The Lack Of Synchronism That Occurs In The Subtitles When Produced During The Broadcast Of Live Tv Programs Or Other Programs That Have Some Improvised Parts. Furthermore, It Also Aims To Resolve The Problematic Interphase Of Synchronized And Unsynchronized Parts Of Mixed Type Programs. In Addition, The Framework Is Able To Synchronize The Subtitles Even When They Do Not Correspond Literally To The Original Audio And/Or The Audio Cannot Be Completely Transcribed By An Automatic Process. Sub-Sync Has Been Successfully Tested In Different Live Broadcasts, Including Mixed Programs, In Which The Synchronized Parts (Recorded, Scripted) Are Interspersed With Desynchronized (Improvised) Ones

The Relationship Between Methadone Familiarity and Methadone Opinions Among Community Corrections Staff

The United States is in the midst of an opioid crisis. Fortunately, effective treatments for opioid use disorder exist (OUD); however, they are underutilized. Medications for opioid use disorder (MOUDs) decrease death by 50 %. These MOUDs are particularly relevant in the criminal justice population given that this population has a higher OUD disease burden but is less likely than the general population to receive this life-saving treatment. Research has identified negative attitudes toward MOUDs among corrections staff as a barrier to utilizing MOUDs. This thesis examines the relationships between community correction staff familiarity with methadone, one type of MOUD, and their opinions toward methadone using extant data from the Criminal Justice Drug Abuse Treatment Studies 2 (CJ-DATS 2) series. These data were collected between 2010-2012. The study was guided by the Knowledge-Attitude Behavior (KAB) model. The data are described using descriptive statistics, and I estimate logistic regressions to examine the relationship between respondent familiarity with methadone and their attitude toward methadone while controlling for other covariates. With a sample of 167 corrections employees, I found that corrections staff who agreed or strongly agreed with the statement that they were familiar with methadone had more positive methadone attitudes. Future research should examine the relationship between familiarity/knowledge, attitudes, and behaviors in other criminal justice settings and for other MOUDs (i.e., buprenorphine and naltrexone)
