Authors: Meléndez Nelly , Briceño Magally , Giberton Jaime , Lucente Rosina
Published: April 2023

El objetivo de esta investigación es analizar los sentimientos expresados por los profesores en torno a su participación en un programa de actualización docente. Para ello se utilizó la minería del texto como un proceso de investigación que permite el manejo automático de datos a partir de lenguaje natural, a fin de identificar patrones, descubrir relaciones, tendencias, desviaciones y obtener nueva información para la toma de decisiones en diferentes ámbitos, entre ellos los programas educativos. El estado del arte de este objeto de estudio partió de una conceptualización de la minería de texto y la aplicación de la inteligencia artificial, debido a los aportes significativos que han brindado a la educación y al proceso de análisis de los sentimientos. Se parte del supuesto que se puede proponer la minería de datos para el estudio de percepciones motivacionales en programas de capacitación. La metodología utilizada fue cuantitativa y cualitativa, el análisis del texto se realizó mediante el método AnalyzeSentiment (Google, 2022). Los resultados demuestran que el análisis de las opiniones emitidas por los docentes, atendiendo a preguntas intencionales, puede analizarse para generar un enfoque eficaz en programas de formación. Se concluye que la combinación de métodos de inteligencia artificial para el análisis de lenguaje natural, junto con técnicas de estadística descriptiva y análisis del discurso constituye un enfoque viable para el análisis de datos y sentimientos para mejorar la transmisión de mensajes que se utilizan en el aula de clase.

Published: April 2023

El proceso de democratización de los estudios superiores favoreció el acceso de grupos que tradicionalmente quedaban fuera de la universidad. Esto despertó nuevos debates, nueva normativa y la creación de universidades en Argentina en zonas desfavorecidas. Una de ellas es la Universidad Nacional de Tierra del Fuego, Antártida e Islas del Atlántico Sur que se ubica en la provincia del mismo nombre. En la creación de esta universidad, la enseñanza de las lenguas extranjeras parecía ocupar un lugar al igual que el resto de las disciplinas. Pero a medida que se fue construyendo su matriz organizacional, definiendo el Estatuto Universitario y conformando las ofertas académicas, se redujo a “cursos extracurriculares” y las y los docentes especialistas en lenguas parecen no formar parte del personal académico. Esto repercute en la enseñanza a estudiantes de las Licenciaturas en Biología, en Geología y en Ciencias Ambientales quienes deben acreditar un buen nivel de conocimientos en lengua extranjera inglés (LEI) a través de un examen para obtener su titulación, sin existir la enseñanza formal de esta como una asignatura del plan de estudio y sin ser un requisito explícito para el cursado de otras asignaturas. Para conocer este proceso y en el que se encuentran la LEI en esta institución, se hizo una lectura de las leyes de: (a) Educación Superior, (b) Creación de la UNTDF, el Estatuto Universitario (provisorio y definitivo). Estos documentos abren el camino a un diseño particular de política lingüística. Documentos que permiten comprender las formas en que se planificará la enseñanza del inglés como lengua extranjera y cómo se utilizará esta en esta comunidad educativa en particular.

Se registra por primera vez para Panamá el hiperparasitismo sobre una larva de Hypercompe muzina (Oberthür, 1881) (Lepidoptera: Erebidae) parasitada, en la que se desarrolló 296 capullos (pupas) pertenecientes al parasitoide primario y gregario de Cotesia congregata (Say, 1836) (Hymenoptera: Braconidae), después de siete días de la colecta. Se obtuvo de los 296 capullos, un total de 280 individuos del parasitoide C. congregata, con una relación de sexo de 277 hembras y 3 machos. Simultáneamente se obtuvo 16 avispas hiperparasitoides del género Conura sp (Ceratomisca) del subgrupo immaculata, con una relación de sexo,14 hembras y 2 machos, que emergieron de los capullos de Cotesia congregata. La diversidad de hiperparasitoides que se reportan en la literatura son seis géneros, tres familias y dos superfamilias. Este trabajo aporta al conocimiento sobre parasitoides primarios y secundarios; comportamiento de algunas avispas parasitoides que podrían ser una alternativa de uso que debería ser analizada para la inclusión a programas de control biológico en nuestro país, a fin de optar por estas técnicas en sistemas agrícolas, forestales, y utilizar menos compuestos contaminantes, e incorporando especies nativas y de esa manera minimizar efectos dañinos al medio ambiente.

Published: April 2023

Las moscas de la fruta son un problema en todos los frutales de la zona, siendo Chrysophyllum cainito la especie más afectada por la pulpa muy dulce de sus frutos. Se ha recolectado en el mes de enero muestras de 25 frutos premaduros, 25 frutos maduros de la planta y 25 frutos caídos en el suelo. Los frutos fueron acondicionados en frascos de plástico con ligas y tul para la recuperación de adultos. Otros frutos fueron partidos para observar pulpa y semilla afectados por las larvas. Se encontró dos especies de moscas de familias distintas, la primera Anastrepha serpentina (Diptera Tephritidae) y la segunda Pectictus testaceus (Diptera Stratiomyidae) como nuevo registro, ambos están presentes en los frutos premaduros y maduros. Los frutos premaduros en la planta están afectados en un 56% y los frutos maduros en la planta están afectados en un 88%, lo cual demuestra un alto porcentaje de daños que realizan ambas especies de moscas, que se traducen en grandes pérdidas económicas. Ambas especies afectan el mesocarpio o pulpa del fruto; asimismo, la especie P. testaceus también barrena el endocarpio o semilla haciéndolo inservible, ya que los cotiledones se transforman en excremento marrón de la larva con la consecuente pudrición por hongos. Se ha observado que ya los frutos premaduros tienen lesiones en la semilla, lo cual demuestra que P. testaceus afecta frutos desde la misma planta. Asimismo, predomina P. testaceus (60,8%) sobre A. serpentina (39,2%).

Published: April 2023

The increasing demand of making the roads safer has trigged a lot of companies to develop complete self- driving cars. A self-driving car requires a great number of different sensors as gyros, radars, GPS, tachymeters etc. and advanced software. This thesis will focus on the possibilities of using only light sensing devices for a tracking robot and examine the advantages and disadvantages of this. The purpose is to investigate which type of light sensor is more suitable for a tracking robot and what the limitations of a tracking robot using this technology are. A demonstrator using two light sensors for controlling speed and direction and a color sensor to avoid obstacles will be built. Apart from choosing the most suitable sensor for a light-tracking robot the sensing distance and range of the chosen one will be tested. To investigate the different light-tracking possibilities and the accuracy of the demonstrator, the vehicle will be put in an open indoor space with arranged colored luminous obstacles. The robot will be tested in both a completely dark room and a lit room. The intention with the outcome is to see the differences of the robots behaviour when disturbances from surrounding light are added as an additional aspect. The results from the test are presented and the use of different sensors are discussed. The final conclusion on using light sensing for a tracking robot is that it is an easy and inexpensive method, but it should be used as a complement to other sensing devices not as a stand-alone method.

Change-of-Direction Speed in Firefighter Trainees: Fitness Relationships and Implications for Occupational Performance
Authors: Lockie Robert , Orr Robin Orr , Montes Fernando , Dawes J. Jay
Published: April 2023

Change-of-direction (COD) speed and ability could assist a firefighter moving about the fire ground more efficiently. There has been limited investigations of COD speed in firefighter trainees, and what measures of fitness could contribute to faster performance in a test such as the Illinois agility test (IAT), which measures longer COD speed. This study analyzed archival data from 292 trainees (262 males, 30 females). The trainees completed the following fitness tests at their training academy: IAT, push-ups, pull-ups, leg tucks, 20-m multistage fitness test to measure estimated maximal aerobic capacity (V̇O2max), backwards overhead 4.54-kg medicine ball throw (BOMBT), 10-repetition maximum (10RM) deadlift, and a 91.44-m farmer’s carry with 2 x 18-kg kettlebells. Independent samples t-tests compared male and female trainees to determine the need to control for trainee sex in the analyses. Partial correlations, controlling for trainee sex, analyzed relationships between the IAT and fitness tests. Stepwise regression analyses controlling for trainee sex determined if any fitness test predicted the IAT. On average, male trainees outperformed females in all fitness tests (p ≤ 0.002). The IAT significantly related to all fitness tests (r = ±0.138–0.439, p ≤ 0.019), and was predicted by trainee sex, estimated V̇O2max, the 10RM deadlift, BOMBT, and the farmer’s carry (R = 0.631; R2 = 0.398; adjusted R2 = 0.388). The results indicate the trainees who are generally fit may perform well in a range of different fitness tests, including the IAT. Nonetheless, improving muscular strength (measured by the 10RM deadlift), total-body power (BOMBT), and metabolic capacity (estimated V̇O2max, farmer’s carry) could enhance COD speed in firefighter trainees.

Published: April 2023

The aim of this study was to investigate the peak running, mechanical, and physiological demands of players of different positions in professional men's field hockey matches. Eighteen professional male field hockey players participated in the study, and data were collected in eleven official matches. Players wore GPS units (Vector S7, Catapult Sports) and heart rate (HR) monitors (Polar H1, Polar Electros) to collect physical and physiological data. Physical and physiological output of forwards, midfielders, and defenders in full matches and during 1-min peak periods was analysed. For all metrics and positions, the values identified for the 1-min peak periods were greater than the average values of match play (p < 0.05). In terms of 1-min peak period Player Load, all three positions were significantly different from each other. Forwards achieved the highest Player Load per minute, while defenders the lowest. The distance per minute, high-speed distance per minute, and the relative average heart rate of defenders were significantly lower than of midfielders and forwards (p < 0.05). The current study revealed the peak running, mechanical, and physiological demands of professional men’s field hockey matches. It is recommended when prescribing training programmes, to consider not only match average demands, but also peak demands. Forwards and midfielders displayed similar peak demands, while defenders had the lowest demands in all metrics except the number of accelerations and decelerations per minute. Player Load per minute can be used to identify the differences in peak mechanical demands between forwards and midfielders.
Influence of Target Width and Distance
on Postural Adjustments in a Fencing Lunge
Authors: Akbas Anna , Marszalek Wojciech , Brachman Anna , Juras Grzegorz
Published: April 2023

The aim of this study was to examine whether target width and target distance influence the planning phase of a fencing lunge (early and anticipatory postural adjustments) as well as the execution phase of a fencing lunge. Eight elite female fencers participated in the study. The displacement of the center of foot pressure, muscle activity of the tibialis anterior, and kinematics of center of mass were recorded using force plates. The results show that target width and distance have no effect on early and anticipatory postural adjustments as well as the acceleration and velocity of the center of mass at the moment of foot-off. However, a greater target distance was associated with a greater max center of mass acceleration and velocity, and larger target width resulted in a greater max center of mass acceleration during lunging (p < 0.05). We suppose that the effect of task parameters on preparing a fencing lunge may be mitigated due to the specific technique adopted by expert fencers and the ballistic nature of a fencing lunge.
Rating of Perceived Exertion in Professional Volleyball:
A Systematic Review
Authors: Rebelo André , Pereira João R. , Martinho Diogo V. , Valente-dos-Santos João
Published: April 2023

The rating of perceived exertion (RPE) it's a non-invasive, cost effective, and time efficient strategy to measure load. However, data can be collected without following specific procedures and across a range of methods (e.g., different RPE scales and/or different operational questions). Consequently, practitioners working in professional volleyball can use this information in various ways with different assessment standards between them. Therefore, the purpose of the current review was to systematically and critically evaluate the use of RPE-based methods in professional volleyball athletes. Electronic searches were conducted in four databases (PubMed, SPORTDiscus, Scopus, and Web of Science). The electronic search yielded 442 articles in which 14 articles were included in the systematic review. All included studies used the BORG-CR10 scale to calculate the session RPE. The main findings indicate that, to minimize the effect of the last exercise of the session, the athlete should be presented with the RPE question 10 to 30 minutes after the session is finished. Plus, in order, to evaluate the intensity of the training session, the question should be “how hard/intense was your session?”, avoiding questions without these adverbs or adjectives such as “how was your training session/workout?”. Future studies should analyse the collection of the localized RPE responses in professional volleyball athletes and their relationships with objective markers such as number of jumps and accelerations.

The purpose of the current study was to investigate the effect of acute BJ ingestion on neuromuscular and biochemical variables in amateur male sport climbers. Ten physically active sport climbers (28.8 ± 3.7 years) underwent a battery of neuromuscular tests consisting of the half crimp test, the pull-up to failure test, the isometric handgrip strength test, the countermovement jump (CMJ) and the squat jump (SJ). Participants performed the neuromuscular test battery twice in a cross-over design separated by 10 days, 150 min after having consumed either 70-mL of BJ (6.4 mmol NO3-) or a 70-mL placebo (0.0034 mmol NO3-). In addition, nitrate
(NO3-) and nitrite (NO2-) saliva concentrations were analysed, and a side effect questionnaire related to ingestion was administrated. No differences were reported in particular neuromuscular variables measured such as the CMJ (p = 0.960; ES = 0.03), the SJ (p = 0.581; ES = −0.25), isometric handgrip strength (dominant/non dominant) (p = 0.459–0.447; ES = 0.34–0.35), the pull-up failure test (p = 0.272; ES = 0.51) or the maximal isometric half crimp test (p = 0.521–0.824; ES = 0.10–0.28). Salivary NO3- and NO2- increased significantly post BJ supplementation compared to the placebo (p < 0.001), while no side effects associated to ingestion were reported (p = 0.330–1.000) between conditions (BJ/placebo ingestion). Acute dietary nitrate supplementation (70-mL) did not produce any statistically significant improvement in neuromuscular performance or side effects in amateur sport climbers.

Adequacy of Normative-Legal Framework for Engaging the Military Forces of the Republic of Serbia in Emergency Situations
Authors: Komazec Nenad , Kovačević Nenad , Bjelica-Vlajić Iris
Published: April 2023

Engagement of military forces of the Republic of Serbia is determined by the national legislation. The operationalisation of engagement of military forces of the Republic of Serbia is regulated in more detail by strategic-doctrinal documents of the National Security system and rules of use of the Serbian Armed Forces. However, engagement of military forces in peacetime (emergency situations) is specific, from the point of view of ambient conditions for use, i.e. dimensions of the operational environment in which military forces are used. Consequently, clearly defined procedures and methodologies for use of military forces are necessary, which nominally requires precise normative-legal determinants. The existence of adequate normative-legal determinants of engagement of military forces in emergency situations is a problem that is being researched in the paper. The solution to the problem, that is, the goal of the work, is achieved by applying the basic method used in the research is the method of content analysis. A special instrument-sheet for content analysis was constructed for its application. A total of 66 normative-legal documents were examined, which can be divided into four groups: laws; regulations; decrees and decisions; and assessments and instructions. The research, at the level of scientific description, led to the following results: the normative-legal framework of the Republic of Serbia enables the use of military forces in emergency situations; the existing legislation is not adequately regulated, so it is necessary to regulate the use of military forces more closely, with a focus on regulating connections and relations at different levels of coordination of entities and forces of disaster risk reduction and emergency management systems.

Abstract. Atmospheric aerosol particles have a profound impact on Earth’s climate by scattering and absorbing solar and terrestrial radiation and by impacting the properties of clouds. Research aircraft such as the Deutsches Zentrum für Luft- und Raumfahrt e.V. (DLR) Falcon are widely used to study aerosol particles in the troposphere and lower stratosphere. However, transporting a representative sample to the instrumentation inside the aircraft remains a challenge due to high airspeeds and changing ambient conditions. In particular, for high-quality coarse mode aerosol measurements, knowledge about losses or enhancements in the aerosol sampling system is crucial. In this study, we present a detailed characterization of the Falcon aerosol sampling system. Aerosol number size distributions were measured during the A-LIFE field campaign simultaneously with in-cabin and out-cabin/wing-mounted instrumentation. Sampling efficiencies were derived for different true airspeed ranges by comparing the in-cabin and the out-cabin particle number size distributions during flight sequences with a major contribution of mineral dust particles in the coarse mode size range. Additionally, experimentally derived Stokes numbers were used to calculate the cut-off diameter of the A-LIFE aerosol sampling system for different particle densities as a function of true airspeed. The results show that the velocity of the research aircraft has a major impact on the sampling of coarse mode aerosol particles with in-cabin instruments. For true airspeeds up to about 190 m s-1, aerosol particles larger than about 1 µm are depleted in the sampling system of the Falcon during the A-LIFE project. In contrast, for true airspeeds higher than 190 m s-1, an enhancement of particles up to a diameter of 4 µm is observed. For even larger particles, the enhancement effect at the inlet is still present, but inertial and gravitational particle losses in the transport system get more and more pronounced which leads to a decreasing overall sampling efficiency. In summary, aerosol particles can either be depleted or enhanced at an aerosol inlet, whereas transport in sampling lines always leads to a loss of particles. Therefore, it is important to consider both, inlet and transport efficiency, when quantifying the sampling efficiency of an aerosol sampling system.

Abstract. Winter near-surface temperatures have important implications for ecosystem functioning such as vegetation dynamicsand carbon cycling. In cold environments, seasonal snow cover can exert a strong control on the surface temperatures.However, the lack of in situ measurements of both snow cover and surface temperatures over high latitudes has made it difficultto estimate the spatio-temporal variability of this relationship. Here, we quantified the fine-scale variability of winternear-surface temperatures (+2 cm) and snow cover duration using a total of 441 microclimate loggers in seven study areasacross boreal and tundra landscapes during 2019–2021. We further examined the drivers behind this variation and the extentto which surface temperatures are buffered from air temperatures during winter. Our results show that while average winternear-surface temperatures stay close to 0 °C across the study domain, there are large differences in their fine-scale variabilityamong the study areas. Areas with large topographical variation, as well as areas with shallow snowpacks, showed the greatestvariation in near-surface temperatures and in the insulating effect of snow cover. In the tundra, for example, differences inminimum near-surface temperatures were close to 30 °C. In contrast, flat topography and deep snow cover lead to little spatialvariation and decoupling of the near-surface and air temperatures. Quantifying and understanding the landscape-wide variationin winter microclimates improves our ability to predict the local effects of climate change in the rapidly warming boreal andtundra regions.

Published: April 2023

Abstract. State-of-the-art snow sensing technologies currently provide an unprecedented amount of data from both remote sensing satellites and ground sensors, but their assimilation into dynamic models is bounded to data quality, which is often low − especially in mountain, high-elevation, and unattended regions where snow is the predominant land-cover feature. To maximize the value of snow-depth measurements, we developed a Random Forest classifier to automatize the quality assurance/quality control (QA/QC) procedure of near-surface snow depth measurements collected through ultrasonic sensors, with particular reference to differentiate snow cover from grass or bare ground data and to detecting random errors (e.g., spikes). The model was trained and validated using a split-sample approach of an already manually classified dataset of 18 years of data from 43 sensors in Aosta Valley (north-western Italian Alps), and then further validated using 3 years of data from 27 stations across the rest of Italy (with no further training or tuning). The F1 score was used as scoring metric, being it the most suited to describe the performances of a model in case of a multi-class imbalanced classification problem. The model proved to be both robust and reliable in the classification of snow cover vs. grass/bare ground in Aosta Valley (F1 values above 90 %), yet less reliable in rare random-error detection, mostly due to the dataset imbalance (samples distribution: 46.46 % snow, 49.21 % grass/bare ground, 4.34 % error). No clear correlation with snow-season climatology was found in the training dataset, which further suggests robustness of our approach. The application across the rest of Italy yielded F1 scores on the order of 90 % for snow and grass/bare ground, thus confirming results from the testing region and corroborating model robustness and reliability, with again a less skillful classification of random errors (values below 5 %). This machine learning algorithm of data quality assessment will provide more reliable snow ground data, enhancing their use in snow models.
4DVarNet-SSH: end-to-end learning of variational interpolation schemes for nadir and wide-swath satellite altimetry

Published: April 2023

Abstract. The reconstruction of sea surface currents from satellite altimeter data is a key challenge in spatial oceanography, especially with the upcoming wide-swath SWOT (Surface Water and Ocean and Topography) altimeter mission. Operational systems, however, generally fail to retrieve mesoscale dynamics for horizontal scales below 100 km and timescales below 10 d. Here, we address this challenge through the 4DVarnet framework, an end-to-end neural scheme backed on a variational data assimilation formulation. We introduce a parameterization of the 4DVarNet scheme dedicated to the space–time interpolation of satellite altimeter data. Within an observing system simulation experiment (NATL60), we demonstrate the relevance of the proposed approach, both for nadir and nadir plus SWOT altimeter configurations for two contrasting case study regions in terms of upper ocean dynamics. We report a relative improvement with respect to the operational optimal interpolation between 30 % and 60 % in terms of the reconstruction error. Interestingly, for the nadir plus SWOT altimeter configuration, we reach resolved space–timescales below 70 km and 7 d. The code is open source to enable reproducibility and future collaborative developments. Beyond its applicability to large-scale domains, we also address the uncertainty quantification issues and generalization properties of the proposed learning setting. We discuss further future research avenues and extensions to other ocean data assimilation and space oceanography challenges.

Pidana penjara merupakan jenis pidana yang selalu diancamkan pada semua jenis kejahatan, tidak terkecuali bagi pengguna narkotika tanpa hak. Penerapan sanksi pidana bagi pengguna narkotika ini penulis pandang tidak lagi sejalan dengan tujuan hukum yang harus memenuhi unsur keadilan, kemanfaatan dan kepastian hukum. Penulis menilai sudah waktunya untuk merujuk pendekatan dekriminalisasi dalam upaya pemidanaan bagi pengguna narkotika yang saat ini menjadi objek pada tatanan hukum pidana Indonesia di dalam Undang-Undang nomor 35 Tahun 2009. Sudaut pandang yang menjadi alasan ketidak cocokan penerapan ini adalah dari kriminologi dan viktimologi yang melanggar tiga unsur tujuan hukum. Berdasarkan latar belakang tersebut penulis tertarik untuk melakukan penelitian untuk meninaju kembali terkait kedudukan hukum pengguna narkotika yang saat ini merupakan perbuatan pidana dengan pendekatan tujuan hukum yaitu untuk keadilan, kemafaatan dan kepastian. Adapun rumusan masalah; (a) Bagaimana kedudukan hukum pengguna narkotika di hukum positif Indonesia! (b) Bagaimana solusi dalam memnuhi keadilan, kemanfaatan dan kepastian hukum bagi pengguna narkotika! Penelitian yang dilakukan dalam penelitian ini adalah penelitian hukum normatif. Yaitu jenis penelitian tersebut menekankan pada pencarian fakta-fakta yang valid dan akurat mengenai sebuah peristiwa konkrit.
