Utilización de Programas Computacionales y Materiales Digitales durante Procesos de Evaluación del Aprendizaje: Percepción de Docentes y Discentes de Educación Superior
Authors: Gallardo Katherina E. 
Published: October 2023

Este artículo presenta los resultados de un estudio de caso que se realizó con el objetivo de comprender cómo se está vinculando el uso de tecnología computacional y el uso de materiales digitales en los procesos de evaluación del aprendizaje en un escenario de educación superior, específicamente en la materia de contabilidad administrativa. Se realizaron observaciones sobre procesos de evaluación sumativa. También se entrevistó a docentes y estudiantes para comprender su percepción sobre las implicaciones formativas que emanan de la decisión de hacer uso de las TICs en procesos de verificación del aprendizaje. Los hallazgos permitieron la comprensión de diferentes factores que convergen en la decisión de utilizar o no TICs en el proceso de evaluación tales como: la concepción que tiene el docente sobre el propósito y diseño de un examen, la vinculación entre evaluación y aprendizaje, así como la inseguridad y desconfianza que genera la apertura a posibilidades de plagio, de fallas tecnológicas, además de caer en el riesgo de propiciar un ambiente de inequidad ante el desafío que implica manejar con pericia dichas herramientas; todos éstos, factores que provocan desaceleración en la inserción de las herramientas tecnológicas en procesos de verificación del aprendizaje.Palabras clave: Evaluación sumativa, programas computacionales, materiales digitales, educación superior. This article contains the results of a case study in a higher education institution context. The objective was getting to comprehend in a deeply way how are computing programs and digital materials being used for summative assessment purposes in management accounting lectures. Observations during computing exam applications as well as some interviews were held with both, professors and students to get their perceptions about consequences of deciding to use or not computing programs and support digital material. Findings revealed a conjunction of factors that permit deep comprehension about some attitudes towards the usage of computing tools. Indeed, insecurity and mistrust are reasons that involve decisions such as not using computing technology during examinations. Risks related to plagiarism possibilities and unfair conditions to solve exams are some of the reasons why computing technology is not becoming a familiar part of examinations tools in higher education.Keywords: Summative assessment, computer programs, digital materials, higher education.

Purpose: This semi-experimental research aimed at achieving two objectives: 1) to develop the research competency of pre-service teachers in early childhood education through the use of a peer coaching process, and 2) to compare the research competency of pre-service teachers in early childhood education before and after implementing the peer coaching process. Methodology: The research sample consists of 30 second-year pre-service teachers in the early childhood education program who are enrolled in research classes in the 2021 academic year, selected through cluster random sampling. The research tools used include activities planned with a peer coaching process and a pre-service teacher research competency assessment form. The statistical analysis employed the mean and standard deviation. Findings: The findings revealed that: 1) pre-service teachers demonstrated good research competency when using the peer coaching process (mean = 3.97, SD = 0.52), and 2) the research competency of pre-service teachers in early childhood education after the implementation of the peer coaching process was at a higher level (good level) compared to their competency level before the trial of the peer coaching process (fair level). The statistical significance was set at .05. Conclusion: Upon closer examination, it was found that the participants exhibited good performance in all aspects, except for writing research reports and presenting research findings. Furthermore, the research competencies of the post-experimental early childhood education students were significantly higher than before the reciprocal coaching process. Practical Implications: This study can be implemented in the classes to improve the competency of student's research ability by applying these coaching methods.

Pebbles, graphs and equilibria: Higher order shape descriptors for sedimentary particles
Authors: Ludmány Balázs , Domokos Gábor 
Published: October 2023

AbstractWhile three-dimensional measurement technology is spreading fast, its meaningful application to sedimentary geology still lacks content. Classical shape descriptors (such as axis ratios, circularity of projection) were not inherently three-dimensional, because no such technology existed. Recently a new class of three-dimensional descriptors, collectively referred to as mechanical descriptors, has been introduced and applied for a broad range of sedimentary particles. First-order mechanical descriptors (registered for each pebble as a pair {S, U} of integers), refer to the respective numbers of stable and unstable static equilibria and can be reliably detected by hand experiments. However, they have limited ability of distinction, as the majority of coastal pebbles fall into primary class . Higher-order mechanical descriptors offer a more refined distinction. However, for the extraction of these descriptors (registered as graphs for each pebble), hand measurements are not an option and even computer-based extraction from 3D scans offers a formidable challenge. Here we not only describe and implement an algorithm to perform this task, but also apply it to a collection of 271 pebbles with various lithologies, illustrating that the application of higher-order descriptors is a viable option for geologists. We also show that the so-far uncharted connection between the two known secondary descriptors, the so-called Morse–Smale graph and the Reeb-graph, can be established via a third order descriptor which we call the master graph.

Atmospheric conditions influence various sectors of human activity, so it is important to study the dynamics of the atmospheric layers, especially those related to temperature fluctuations. The aim of this research is to investigate the model of temperature fluctuations in the tropopause layer (at an altitude of 17 km) by determining the wave amplitude and phase parameters. The method for obtaining parameters is defined as simulated annealing inversion, which is a simulation of finding solutions at global critical points. The data used in this study are temperature at 17 km, which retrieved from the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) Mission #2 GNSS radio occultation satellite during April–May 2021. The results of the annealing simulation show that the amplitude and phase parameters of atmospheric waves in the tropopause layers vary between 3.4–23.86 K and 7.3–52.5°, respectively. The simulation model shows that the temperature spreads from west to east and fluctuates between –25 and 25 K.Keywords: Atmospheric Waves, Simulated Annealing, Temperature, Tropopause Layer.

A regression tree is a data analysis technique that aims to determine the effect of all explanatory variables on the response variables. However, it turns out the regression tree method has a weakness that is the hierarchical structure allows for high variance predictors. The weakness of this regression tree method can be above using the Boosted Regression Trees (BRT) approach. The BRT approach uses a boosting technique to combine multiple regression trees in an additive manner so that the resulting variance is smaller than the previous variance. This study uses the BRT method for a case study of factors affecting the level of crime in East Java in 2018. Through 89 obtained optimal trees, the most important crime rate factors are the number of youth (model importance of 31.86%), followed by the percentage of poor population (11.14%), junior high school gross enrollment rate (9.67%), elementary school gross enrollment rate (8.98%), road stability (8.81 %), senior high school gross enrollment rate (8.67%), distance to the capital city of Surabaya (7.25%), open unemployment rate (7.02%), Gross Domestic Regional Product (GRDP) (5.32%), and population density (1.25%)..Keywords: Boosted Regression Trees, Boosting, Crime Rate, Regression Trees.AbstrakPohon regresi merupakan teknik analisis data yang bertujuan untuk mengetahui pengaruh semua peubah penjelas terhadap peubah responnya. Namun, ternyata metode pohon regresi memiliki kelemahan yaitu struktur hierarkisnya memungkinkan terjadinya varians yang tinggi. Kelemahan metode pohon regresi ini dapat diatasi dengan menggunakan pendekatan Boosted Regression Trees (BRT). Pendekatan BRT menggunakan teknik boosting untuk menggabungkan beberapa pohon regresi secara aditif sedemikian sehingga nilai varians yang dihasilkan lebih kecil dari nilai varians sebelumnya. Penelitian ini menggunakan metode BRT untuk studi kasus menentukan faktor-faktor yang memengaruhi tingkat kriminalitas di Jawa Timur tahun 2018. Melalui 89 buah pohon optimal yang terbentuk, diperoleh kesimpulan bahwa faktor yang memengaruhi tingkat kriminalitas tertinggi adalah jumlah pemuda (31,86%), diikuti oleh persentase penduduk miskin (11,14%), Angka Partisipasi Kasar (APK) SMP (9,67%), APK SD (8,98%), kemantapan jalan (8.81%), APK SMA (8,67%), jarak ke ibukota Surabaya (7,25%), tingkat pengangguran terbuka (7,02%), Produk Domestik Regional Bruto (5,32%), dan kepadatan penduduk (1,25%).

Published: October 2023

The capacitated vehicle routing problem (CVRP) is a problem of distributing a number of goods using vehicles with limited carrying capacity that needed to pick up or deliver items at various locations, such as round trips from a store to customers. The goal of CVRP is to obtain a route with shortest travel distance. This research proposed the combination of genetics algorithm with simulated annealing (GASA) to solve CVRP. The first step in GASA is to represent customer as chromosomes, calculate fitness values, selection, crossover, and mutation. After that we continue to optimize the problem using SA algorithm by modifying the best solution produced by GA algorithm, comparing the fitness of modified best solution with the best solution of GA, and return to GA algorithm until maximum iteration achieved. Thus, GASA has greater chance to obtain global optimal solution. To simulate the algorithm, GASA was used for CVRP of an ice cream company in Bandung City and was able to solve it well.Keywords: Capacitated Vehicle Routing Problem (CVRP), Genetic Algorithm (GA), Optimization, Simulated Annealing (SA). AbstrakCapacitated Vehicle Routing Problem (CVRP) adalah permasalahan pendistribusian sejumlah barang oleh kendaraan yang tersedia dengan kapasitas tertentu dari suatu depot ke sejumlah pelanggan lalu kembali ke depot. Tujuan penyelesaian CVRP adalah untuk menentukan rute pendistribusian dengan total jarak terpendek. Pada penelitian ini, digunakan gabungan algoritma genetika dan simulated annealing (GASA) untuk menyelesaikan permasalahan CVRP. Algoritma GASA bekerja dengan cara melakukan tahapan-tahapan pada Algoritma GA yaitu merepresentasikan kromosom, menghitung nilai fitness, seleksi, crossover, dan mutasi, kemudian dilanjutkan ke tahapan-tahapan Algoritma SA yaitu memodifikasi solusi terbaik yang diperoleh dari Algoritma GA sebelumnya, membandingkan nilai fitness solusi hasil modifikasi dengan solusi terbaik pada Algoritma GA, setelah itu melakukan kembali tahapan-tahapan Algoritma GA sampai iterasi maksimum tercapai. Dengan demikian gabungan GA dan SA mempunyai peluang besar untuk memberikan solusi optimal global. Hasil implementasi model CVRP dan Algoritma GASA pada masalah pendistribusian es krim suatu perusahaan di Kota Bandung diperoleh kesimpulan bahwa Algoritma GASA dapat menyelesaikan masalah tersebut dengan baik.
Chile: abdicación cívica e historia contra la memoria
Authors: Cassigoli Salamon Rossana 
Published: October 2023

Este artículo recapitula las secuelas existenciales que asolan a familias, localidades e individuos, enmendadas o transmutadas por memoriales humanistas y vanguardistas de la experiencia dictatorial chilena de la década de 1970. Derivaciones inmateriales que han marcado, al menos, a tres generaciones, tres descendencias presentes y convivientes. Los síntomas del olvido y de una “reclamación negada” afloran bajo el peso de la cultura imperante. La presente remembranza bordea la crónica, afín al trabajo de la memoria; compendia fragmentos de interlocución crítica entre la disparidad de presencias que personifican un patrimonio disperso: el de una alteridad perdida y referida a otro tiempo cultural.
Democracia sin ciudadanos: crítica de la teoría de la transición
Authors: Ortiz Sandoval Luis 
Published: October 2023

La tesis de que las formas democráticas basadas en la teoría de la “poliarquía” aseguran los procesos de transición democrática en América Latina es abstracta. La continuidad de las estructuras sociales de desigualdad en la región, demuestra que la construcción de instituciones democráticas es una mera pretensión de “jugar las reglas de juego” y de instaurar por decreto la participación de hombres y mujeres a través de “elecciones libres”, allí donde la gente no es libre ni puede elegir. Este ensayo propone que el punto a considerar en esta problemática es la construcción social de ciudadanía: proceso todavía inconcluso pero que deviene en condición de posibilidad de la democracia misma. A partir de la experiencia paraguaya, se puede constatar que las acciones colectivas no necesariamente apuntan a la creación de condiciones de acceso a la ciudadanía, sino a una cuestión aún previa: la inclusión social de las clases subalternas.

Published: October 2023

Vitamin D deficiency in young children presents a current problem of public health in modern Russia. Statistical data on rickets incidence accounts only moderate and severe cases of rickets that is why the sample surveys in children population detect much more cases of clinical manifestation of vitamin D deficiency or its consequences. The purpose of the study was to find out the prevalence rate of rickets signs and risk factors of vitamin D deficiency in young children aged 1–3. Methodology of research: we used survey methods and content-analysis of out-patient records of a random sample that included 127 children aged 1 to 3 in a children polyclinic of Kursk city. By a specially designed questionnaire clinical symptoms of vitamin D deficiency were detected, risk factors of rickets in anamnesis, use of specific and non-specific antenatal and postnatal prophylaxis of rickets were investigated. Results of the study: minimum two signs of rickets were detected in children by 53 mothers – respondents (42% of the sample), the most frequent complaints were bald spots on the back of the head (71,7%), excessive back of the head sweating (58,5%), emotional instability (30,2%), frequent crying (22,6%), anxiety and poor sleep quality (20,8%). There were identified the following factors that had statistically significant association with development of clinical signs of rickets: short breast feeding, maternal complications during pregnancy, absence of specific prophylaxis of vitamin D deficiency in antenatal and postnatal periods (p<0,05). Season of baby’s birth and maternal age did not have statistically significant association with rickets’ signs. Conclusion. The problem of vitamin D deficiency in young children often remains under-reported, so being untreated it can lead to delayed consequences for health of children and adolescents. A particular attention of pediatricians and parents must be paid to specific antenatal and postnatal prophylaxis, prolonged breast feeding until 12–18 months
