Scaffolding to Support Better Achievement in Mathematics
Authors: Murdiyani Nila Mareta
Published: March 2024

According to the National Science Education Standards, teachers should emphasize students’ interests, needs, experiences, inquiry, collaboration and understanding in their classrooms. One of the characteristics of inquiry is using scaffolding. Because of the benefits, it is important to investigate the effect of scaffolding on achievement in mathematics. Based on some relevant previous studies, scaffolding can be used to support better achievement in mathematics. In scaffolding, teacher’s guidance decreases gradually and student’s autonomy increases gradually. By giving guidance, teacher revises student’s misconceptions; while by giving autonomy, teacher supports student’s motivation in learning. Minimizing misconceptions and maximizing motivation can lead students to better achievement in mathematics. Many studies in this paper emphasize the importance of teachers' contribution in giving scaffolding to their students. Further research should be conducted to investigate the role of other people surrounding the students, such as parent and peer, in supporting effective scaffolding.Keywords: scaffolding, achievement in mathematics, misconceptions, motivation

Published: March 2024

Penelitian ini bertujuan menemukan model untuk tingkat pengangguran terbuka di Bali dengan Fuzzy Times series Cheng (FTS Cheng) dan Fuzzy Times series Markov Chain (FTS Markov Chain) serta membandingkan tingkat akurasi kedua model tersebut. Jenis penelitian ini adalah jenis penelitian kuantitatif. Data tingkat pengangguran terbuka di Bali yang digunakan sebanyak 34 dari periode Februari 2006 sampai dengan Agustus 2021. Dari 34 data kemudian dibagi menjadi dua dengan proporsi 30% data latih dan 70% data uji. Tahapan penelitian yang dilakukan dengan menghitung FTS Cheng dan FTS Markov Chain pada data latih kemudian dilanjutkan pada data uji. Selanjutnya model FTS Cheng dan FTS Markov Chain dihitung akurasinya dengan MAPE (Mean Absolute Percentage Error),RMSE (Root Mean Square Error) dan Confusion Matrix (akurasi,presisi,recall). Hasil MAPE yang didapatkan adalah  FTS Cheng sebesar 18.43% dan FTS Markov Chain sebesar 31.19%. Kemudian hasil RMSE yang didapatkan dari FTS Cheng dan FTS Markov Chain secara berturut-turut adalah 0.88 dan 0.63. Pada pengujian menggunakan Confusion Matrix pada FTS Ceng didapatkan hasil akurasi, presisi, recall secara berturut-turut adalah 61.90%,41.22% dan 44.35%. Sedangkan untuk FTS Markov Chain mendapatkan hasil pengujian sebesar 61.90%,49.17% dan 48.75% untuk akurasi, presisi dan recall.

Analisa Kestabilan Bebas Kecanduan pada Penyebaran Penggunaan Media Sosial Berdasarkan Model SEARQS
Authors: Widayati Ratna , Reviladi Intrada
Published: March 2024

Penelitian ini membahas mengenai model penyebaran penggunaan media sosial dan analisa kestabilan di sekitar titik ekuilibrium serta simulasi numeriknya dengan mengasumsikan populasi individu dibagi menjadi 5 kelas yaitu individu yang rentan terhadap kecanduan media sosial, individu yang menggunakan media sosial tetapi belum timbul kecanduan, individu kecanduan/adiktif media sosial, individu sembuh dari kecanduan media dan individu yang berhenti menggunakan media sosial. Model matematika yang digunakan adalah SEARQS dengan asumsi tidak ada kematian karena kecanduan media sosial. Selain itu, individu yang telah berhenti dari kecanduan media sosial, dapat kembali menjadi individu rentan. Permasalahan yang timbul dari penyebaran penggunaan media sosial yang berlebihan adalah bagaimana mengetahui kapan individu yang kecanduan media sosial akan menghilang dari populasi dan kapan individu yang kecanduan media sosial masih akan tetap ada di dalam populasi. Berdasarkan model, diperoleh titik ekuilibrium bebas kecanduan dan titik ekuilibrium endemik. Analisa kestabilan dilakukan di sekitar titik ekuilibrium bebas kecanduan diperoleh hasil bahwa titik ekuilibrium bebas kecanduan stabil asimtotik lokal jika dipenuhi syarat Ro1. Selanjutnya dilakukan simulasi numerik dengan menggunakan program Matlab menghasilkan jika Ro1 populasi individu yang kecanduan media sosial akan menghilang dari populasi sesaat setelah 10 satuan waktu, sedangkan jika Ro1 individu yang kecanduan media sosial masih ada dalam populasi. In this paper we discussed about the model of social media addiction and stability analysis of the equilibrium point as well as its numerical simulation by assuming the individual population is divided into 5 classes, namely Susceptible individual, Expose individuals, Addicted individuals, Recover individuals. The SEARQS model is used. The assumptios used are no deaths due to social media addiction. In addition, individuals who have quit social media addiction may return to being Susceptible individuals. The problem that arises from the spread of excessive use of social media is how to know when individuals who are addicted to social media will disappear from the population and when individuals who are addicted to social media will still be in the population. Based on the model, an addiction-free equilibrium point and an endemic equilibrium point are obtained. The stability analysis was carried out around the addiction-free equilibrium point and the result was that the addiction-free equilibrium point was locally asymptotically stable if the condition  was fulfilled. Furthermore, a numerical simulation using the Matlab program results if , the population of individuals who are addicted to social media will disappear from the population shortly after 10 time units, whereas if , individuals who are addicted to social media are still in the population.

Authors: Hernández Ramírez Eric , Sánchez Vargas Armando , López Herrera Francisco
Published: March 2024

En este artículo analizamos el impacto heterogéneo de un incremento de los costos de las remuneraciones a los trabajadores sobre el nivel de precios general y sectorial de la economía mexicana. Mediante un modelo de precios de insumo producto con funciones de costos flexibles, simulamos escenarios considerando un aumento de 10% en las remuneraciones a los trabajadores. Encontramos que el aumento de precios a nivel de sectores económicos es heterogéneo y depende tanto de su estructura de costos como de cuán flexibles sean dichos sectores para sustituir. A nivel global, para costos fijos un aumento del 10% tiene un efecto sobre la inflación de 2.2%, mientras para costos flexibles de 1.98%. La originalidad de este trabajo consiste en el hallazgo de impactos heterogéneos, dando pie a la propuesta de políticas públicas focalizadas por sector. Naturalmente, el modelo está limitado por los propios supuestos del modelo de insumo producto.
Factors Explaining the Use of Web-Based Consultations With Physicians by Young and Middle-Aged Individuals in China: Qualitative Comparative Analysis
Authors: Zhang Chunyu , Hu Ning , Li Rui , Zhu Aiping , Yu Zhongguang
Published: March 2024

Background

It was only upon the occurrence of the COVID-19 pandemic that the demand for web-based consultations with physicians grew at unprecedented rates. To meet the demand, the service environment developed rapidly during the pandemic.

Objective

This study aimed to identify the current status of the use of web-based consultations with physicians among young and middle-aged Chinese individuals and explore users’ perspectives on key factors that influence its use in terms of optimizing benefits and compensating for disadvantages.

Methods

We conducted semistructured interviews with 65 individuals (aged 18 to 60 years) across China between September and October 2022. The interviewees were selected through snowball sampling. They described their experiences of using web-based physician consultations and the reasons for using or not using the service. Based on the Andersen Behavioral Model, a qualitative comparative analysis was used to analyze the factors associated with the use of web-based physician consultations and explore the combinations of these factors.

Results

In all, 31 (48%) of the 65 interviewees used web-based consultation services. The singular necessary condition analysis revealed that the complementary role of the service and perceived convenience are necessary conditions for the use of web-based consultation services, and user’s confidence in the service was a sufficient condition. Based on the Andersen Behavioral Model, the configuration analysis uncovered 2 interpretation models: an enabling-oriented model and a need-oriented model. The basic combination of the enabling-oriented model included income and perceived convenience. The basic combination of the need-oriented model included complementary role and user’s confidence.

Conclusions

Among the factors associated with the use of web-based consultations, perceived convenience, complementary role, and user’s confidence were essential factors. Clear instructions on the conduct of the service, cost regulations, provider qualifications guarantee, privacy and safety supervision, the consultations’ application in chronic disease management settings, and subsequent visits can promote the positive development of web-based consultations.

Authors: Rettinger Lena , Schönthaler Erna , Kerschbaumer Andrea , Hauser Carina , Klupper Carissa , Aichinger Lea , Werner Franz
Published: March 2024

Background

The acquisition of handwriting skills is essential for a child’s academic success, self-confidence, and general school performance. Nevertheless, an estimated 5% to 27% of children face handwriting challenges, where the ability to modulate pressure on the pencil and lead on the paper is a key motor component.

Objective

We aimed to investigate the experience with and usability of the SensoGrip system, a pressure-measuring pen system with personalized real-time feedback about pressure modulation, in a clinical setting with children and occupational therapists (OTs).

Methods

A multimethods study was conducted, incorporating qualitative interviews and questionnaires with children, user diaries, focus group discussions, and a usability questionnaire with OTs, along with a questionnaire for parents.

Results

The study involved OTs (n=8), children with handwriting difficulties (n=16), and their parents (n=16), each of whom used the SensoGrip system in up to 5 therapy sessions. OTs reported that the SensoGrip system helped to focus the child’s awareness on handwriting pressure and to measure it objectively. The system received high acceptance and usability ratings from the OTs—usefulness: median score of 4 out of 7; ease of use and ease of learning: median score of 6 out of 7; and satisfaction: median score of 6 out of 7. Participants appreciated that it fosters pressure awareness and motivation to draw and write.

Conclusions

The SensoGrip pressure-sensing system with real-time feedback is a promising tool for pediatric occupational therapy. It supports children with handwriting difficulties to adjust their pressure application during the task. In the future, controlled quantitative trials are warranted to further examine the system’s impact.

However, the perceptions of young people and health care professionals’ (HCPs) toward the use of social media for type 1 diabetes self-management have not been systematically reviewed.

Objective

The aim of this study is to explore and summarize the experiences and views of young people with type 1 diabetes and their HCPs on using social media for self-management across qualitative findings.

Methods

We searched MEDLINE, Embase, PsycINFO, and CINAHL from 2012 to 2023 using Medical Subject Heading terms and text words related to type 1 diabetes and social media. We screened and selected the studies according to the inclusion and exclusion criteria. We quality appraised and characterized the included studies and conducted a thematic synthesis.

Results

We included 11 studies in our synthesis. A total of 9 of them were qualitative and 2 were mixed methods studies. Ten focused on young people with type 1 diabetes and 1 on HCPs. All used content analysis and were of moderate to high quality. Thirteen descriptive themes were yielded by our thematic synthesis, contributing to five analytic themes: (1) differences in how young people interact with social media, (2) characteristics of social media platforms that influence their use and uptake for type 1 diabetes self-management, (3) social media as a source of information, (4) impact on young people’s coping and emotional well-being, and (5) impact on support from and relationships with HCPs and services.

Conclusions

The synthesis suggests that we should consider leveraging social media’s peer support capabilities to augment the traditional services for young people with type 1 diabetes. However, the patients may have privacy concerns about HCPs’ involvement in their online activities. This warrants an update of existing guidelines to help young people use social media safely for self-managing their diabetes.
Populist attitudes and support for democracy among Latin American bureaucrats

Despite macro-level patterns that link populists in power with democratic backsliding, it is unclear how populist attitudes correlate with attitudes about democracy among individuals. Scholars have only recently turned their attention to this issue and produced inconclusive results. Using our unique survey of Latin American bureaucrats, we investigate how populism operates among bureaucrats, a set of actors with a crucial role in democratic governance. We analyze each of three dimensions of populism separately (anti-elitism, pro-people orientation and Manicheanism). Building on recent scholarship finding that populists are dissatisfied democrats, we examine the relationship between attitudes about each dimension of populism and satisfaction with and support for democracy. We extend current scholarship by deploying two measures of satisfaction with and four measures of support for democracy, including support for checks on the executive. We find that those scoring high on underlying dimensions of populism rate the quality of democracy lower but are not less satisfied with the system in their countries.  We also find that those with pro-people attitudes consistently support democracy, including checks on the executive. Those with a Manichean outlook, in contrast, are less supportive of democracy and favor increased executive powers. These complexities suggest the need for more research on the concept of populism, as well as supporting the need for understanding how attitudes among important social groups, particularly institutional actors, may differ from the overall population.

improvement of signal communication for a foraging task using evolutionary robotics

Published: March 2024

Communication systems represent an evolutionary advantage for a group of robots solving coordinated tasks. In the field of evolutionary robotics, the emergence and establishment of communication are regulated by different variables. These systems are a tool produced by artificial evolution for the exchange of personal and environmental information. Since evolutionary processes involve multi-objective evolutionary methods, it is important to study all the mechanisms that affect the emergence and establishment of communication systems. One of these variables is the evolutionary advantage of emerging signals. In this article it is assumed that the signals appear because they are evolutionarily useful in solving a task. Emitter and receiver generate a process of conceptualization, which makes the signals associated with a meaning for the community. In this way an experiment is adapted to the FARSA simulator and the MARXBOT robot. This experiment consists of a group of robots that spend as much time as possible in a food zone and avoid a poisoned zone. Under normal conditions, robots tend to point to the food zone to attract the rest of the population. When the evolutionary importance of pointing out the food zone is reduced, the signals arise in different situations such as the presence of nearby objects and the poisoned zone. Communication is configured with the LED rings and linear cameras of the robots. In addition, an ethological method is adapted to quantify the behavioral effects of experimental manipulation.
Identification of geothermal potential zone associated with land surface temperature derived from Landsat 8 data using split-window algorithm
Authors: Akhyar  , Sary C. A.
Published: March 2024

This study was conducted in the geothermal potential area of Mount Seulawah, Aceh province. Study was conducted using remote sensing methods in order to estimate and map the land surface temperature (LST). Data used in this study is Landsat 8 OLI and TIRS. Methods used in this study were split-window algorithm (SWA) to obtain the LST through NDVI analysis and landcover classification, and image enhancement to obtain the lineament density through visual interpretation referring to the results of band ratio and filter techniques. The results of the NDVI analysis show that the study area has a value in the range of -0.57 – 0.97. The results of the LST analysis show that the surface temperature in the area has a value in the range of 21.32 - 32.88 oC. Areas that have high LST values can be estimated as areas that have anomalies. Based on the results of the lineament density analysis, the higher density value in an area can indicate the better permeability where geothermal manifestations come out. The direction of the lineaments that control the study area is dominated by the northwest-southeast in accordance with the direction of the main stress, namely the Seulimum fault and the Aceh fault which also has a northwest-southeast direction. The overall results show that the Seulawah geothermal area is quite potential to be developed for the sustainable natural resource.
Highly efficient relay triggering circuit for fault detection during Power swings
Authors: Akolkar S. M. , Jariwala H. R.
Published: March 2024

This paper introduces a Discrete Wavelet Transform based very simple and fast acting algorithm with multi-resolution analysis to sense all types of faults in presence of power swings using current signal analyzation. The algorithm confirms very quick and efficient detection of various fault types in the first signal decomposition level of signal. The novelty of proposed algorithm lies in use of special type of Battle Lemarie mother wavelet having an advantage of perfect symmetry ensuring decomposition into B-Spline or same order polynomials capturing excellent speed and time-frequency localization of signal. The algorithm is tested for different fault parameters such as fault resistance, fault distance and time of initiation of faults considering EHV double circuit transmission line network and IEEE 9 Bus system developed in MATLAB environment. The proposed algorithm is capable of detecting all types of faults consistently within minimum time of 0.001 sec.
effect of hybrid ratio on the flexural properties of Arenga Pinnata fiber/E-glass fiber/polyester hybrid composites

Published: March 2024

Hybrid ratio effect on flexural properties of sugar palm/E-glass fiber hybrid-reinforced polyester composites has been investigated. Before being embedded, the sugar palm fiber was taken off from its original mesh, washed, alkali-treated, and chopped into ~10 mm long. The specimens were cut from composite plates having different hybrid ratios, fabricated using cold pressed technique. The total fiber volume fraction was kept at ~0.21, where four hybrid ratios, and two span-to-depth ratios were used. The E-glass was arranged unidirectionally and placed right on the surface of a bottom mold and wetted using the matrix, and the SPF was then evenly poured on the wet E-glass arrangement in randomly oriented pattern. Specimen preparation and testing were carried out according to the ASTM D790 standard, where the E-glass sides were placed in tension sides of the beams. It was found that flexural strength, and strain at maximum stress significantly increase with the increase of hybrid ratio.
