Physical fitness, hormonal, and immunological responses during prolonged military field training
2018
Physical fitness is crucial to warfighters’ performance in the battlefield. Previous studies have shown negative changes in their hormonal and neuromuscular responses induced by military field training (MFT). The purpose of this study was to investigate the changes in hormonal and immunological values and body composition during a prolonged MFT and to find out how warfighters’ physical condition influences these changes. Conscripts (n = 49, age 20 1 years, height 179 9 cm, body mass 73.8 7.8 kg, fat 12.6 3.7% and BMI 23 kg/m²) were measured before, during, after MFT, and after a 4-day recovery period. Serum insulin-like growth factor-1 (IGF-1), tumor necrosis factor alpha (TNF-a), interleuk…
Neural and genetic correlates of antidepressant response to sleep deprivation - A functional magnetic resonance imaging study of moral valence decisi…
2007
Context: Total sleep deprivation combined with light therapy causes rapid amelioration of bipolar depression. A polymorphism in the promoter for the serotonin transporter influences both antidepressant response and the structure and function of specific brain areas. Objective: To determine whether antidepressant therapy or the genotype of the serotonin transporter influence the pattern of neural response to a task targeting the depressive biases in information processing (moral valence decision). Design: Before-and-after trial studying the biologic correlates of response to treatment. Setting: University hospital. Patients: Twenty inpatients with bipolar depression. Intervention: Repeated t…
Rapid serial naming: relations between different stimuli and neuropsychological factors.
2004
We report two studies on rapid serial naming (RSN). Study 1 addressed the relations among RSN tasks comprising different stimuli. Separate components for RSN of alphanumeric and non-alphanumeric stimuli, as well as for tasks in which the stimuli alternated between categories were identified. In Study 2, phonological skills, processing speed, motor dexterity, and verbal fluency were found to explain RSN performance. The studies indicate: (1) that RSN tasks vary in their properties according to the stimuli used and according to the way the tasks are arranged, and (2) that RSN tasks are multi-componented.
Lope de Vega y la historia en los escenarios de los siglos XX y XXI
2013
This paper aims to examine, on the one hand, the presence of Lope’s historical dramas on contemporary stage to confirm their continuity; and, on the other, to reflect on the distinctive features of the staging of these dramas from a specific corpus of performances dating from the last decades. The goal is to observe the current relevance of these dramas and performances, to study under what ethical and aesthetic assumptions characters are now represented and the historical episodes that Lope used in the creation of his fictions, as well as to analyze the possible connections between History, Lope and the audience of the 21st century.
Estructura informativa y reformulación: los recapitulativos kurz gesagt y mit einem Wort
2014
Este artículo analiza el papel discursivo de los marcadores de reformulación recapitulativos a partir de una definición del texto como un proceso dinámico de construcción orientado a la satisfacción de un propósito comunicativo concreto. La consideración de las dinámicas que rigen los procesos de producción textual nos permitirán analizar estos marcadores no como meros nexos textuales paratácticos, sino como los mecanismos mediante los que el emisor distribuye y presenta las distintas unidades comunicativas con las que compone su discurso. Mostraremos que kurz gesagt y mit einem Wort cumplen una doble función textual, organizativa y cognitiva, y contribuyen al intento de todo emisor de apro…
Predicting arithmetical achievement from neuro-psychological performance: a longitudinal study
1998
In this article, we show that the performances of 5- to 6-year-old children in arithmetic tests can be predicted from their performances in neuro-psychological tests administered a number of months in advance, independently of their level of development.
Automatic speech recognition in the booth
2020
Abstract Automatic Speech Recognition (ASR) has been proposed as a means to enhance state-of-the-art computer-assisted interpreting (CAI) tools and to allow machine-learning techniques to enter the workflow of professional interpreters. In this article, we test the usefulness of real-time transcription with number highlighting of a source speech for simultaneous interpreting using InterpretBank ASR. The system’s precision is high (96%) and its latency low enough to fit interpreters’ ear–voice span (EVS). We evaluate the potential benefits among first-time users of this technology by applying an error matrix and by investigating the users’ subjective perceptions through a questionnaire. The …
Justice for All? Issues Faced by Linguistic Minorities and Border Patrol Agents during Interpreted Arraignment Interviews.
2015
The Tijuana (Mexico) - San Ysidro (San Diego County, CA) international border is the world’s busiest port of entry. The US Customs and Border Protection Agency hires over 60,000 employees, 21,000 of whom are agents in the US Border Patrol. Several steps must be taken to become a border patrol agent, but being bilingual is not a pre-requisite. In order to communicate with detainees, and interrogate them, the US Border Patrol Agency hires the services of Telephone Interpreting Companies. In this study I present segments of a 2 hour and fifty minute transcript that captures a typical border patrol agent /detainee interaction facilitated by an ad-hoc interpreter. I examine the power differentia…
Is TCP Packet Reordering Always Harmful?
2004
IP networks do not provide any guarantee that packets belonging to the same flow are delivered in the correct order. Out-of-order reception of packets was commonly considered due to pathological network conditions (such as link failures, etc.). However, it has been shown that packet reordering is a phenomenon which occurs even in normal network operation, due to a number of link-level and/or router-level implementation features, such as local parallelism and load balancing. Packet reordering is intuitively considered as a negative phenomenon, which may severely affect TCP traffic performance since it is expected to cause inefficient usage of the available link bandwidth and is expected to i…
Liquid chromatography in pharmaceutical analytics
2017
Tutkielmassa perehdytään nestekromatografian käyttöön lääkeaineanalytiikassa. Korkean erotuskyvyn nestekromatografia (HPLC) on suosittu menetelmä lääkeaineiden analysoinneissa, esimerkiksi pitoisuuksien tai epäpuhtauksien määrityksissä. HPLC-menetelmät voidaan luokitella useisiin alalajeihin ja käänteisfaasinestekromatografia (RP-HPLC) on niistä suosituin lääkeaineanalytiikassa. Tässä kirjallisuuskatsauksessa käsitellään erityisesti nopeaa nestekromatografiaa. Analyysimenetelmiä voidaan nopeuttaa sopivan kolonnin avulla. Tavanomainen HPLC-ajo on mahdollista toteuttaa lyhyemmässä ajassa käyttämällä lyhyttä kolonnia tai kolonnia, jossa partikkelikoko on pieni. Kuitenkin tehokkain tapa on käyt…
