Published: December 2024

This study aims to determine teacher views on the applicability of curricula during the Covid-19 pandemic compulsory remote education. The study adopts the descriptive method and is based on the single survey model. The population comprises teachers working at primary, secondary and Anatolian high school levels in Çankaya, Elmadağ and Bala districts of Ankara, each of which represents three different socioeconomic development levels. The data were collected by using a questionnaire, and frequency and percentage values were used for analysis. Regarding the four basic curriculum components (objectives, content, teaching-learning process and measurement and evaluation), teachers stated that while they used the curriculum when planning instructional activities during the Covid-19 pandemic, they found the objectives unsuitable for the remote education process and felt the need for revision as they believed not all outcomes could be achieved. Teacher views on the suitability of the curriculum content for remote education varied based on their branches of teaching. Regarding teaching-learning experiences, teacher views about student participation in classes also varied based on their branches of teaching and the socioeconomic level of the school's location. Teachers reported practical activities to be insufficient. Regarding the measurement and evaluation component, most teachers, particularly those working in secondary and Anatolian high schools, stated that the cancellation of common exams negatively affected student participation in their classes. Most teachers also reported that classroom assessment activities could only be partially conducted. There is a need to adapt curricula for future emergency remote education events, particularly in terms of developing content and designing measurement and evaluation activities. Additionally, it is recommended that technological support should be provided to teachers and students who still have limited resources today and that training should be provided on technology use.
Can Laws Send the Right Message: Understanding the Assumptions and Costs Associated with Using Legal Expression as a Tool for Social Change
Authors: Roy Shubhangi
Published: December 2024

Laws send a message – or so we assume. Law and economics scholars argue that it may do so through mere expression. Since this requires no active enforcement, legal expression has become a popular policy tool. This article questions both the strength of legal expression for social change as well as its costlessness by focusing on the institutional conditions essential for legal expression to work. First, legal expression requires that people have good legal knowledge. At least, their legal knowledge should be better than their social knowledge. Second, individuals must be interested in the attitudes of a ‘homogenized whole’ of which law is a credible source of information. As the article highlights, neither of these two conditions exist in most contexts. As importantly, the article explains how over-utilizing legal expression in such ill-suited contexts further undermines the power of future laws in creating change, with or without enforcement.

Published: December 2024

The increasing demand for higher bandwidth and reliable communication networks driven by next-generation mobile technologies (5G/6G) and the Internet of Things (IoT) poses challenges for existing communication infrastructures. Free Space Optics (FSO) offers high-speed wireless data transmission comparable to fiber optics but suffers from significant performance degradation due to environmental factors such as rain, fog, and atmospheric turbulence. This study investigates the potential of a hybrid Dense Wavelength Division Multiplexing (DWDM)-FSO system to overcome these challenges. By combining DWDM’s high capacity with the flexibility of FSO links, the system achieves a data rate of 5.4 Tbps across 90 users. Simulations conducted using OptiSystem software evaluate the impact of different weather conditions – clear skies, heavy rain, and dense fog – on performance. Key metrics, including bit error rate (BER), quality factor (Q-factor), and eye diagrams, are analyzed to assess signal integrity and reliability. A comparative study of Single Input Single Output (SISO) and MIMO configurations (2 × 2 and 3 × 3) shows that the 3 × 3 MIMO-FSO setup significantly enhances performance, maintaining signal quality and extending range under adverse weather. These findings highlight the hybrid DWDM-FSO system’s potential to deliver high-speed, resilient communication, ensuring seamless connectivity in dynamic environments.

Avaliação dos Indicadores de Performance na Análise de Eficácia dos Bancos de Perfis Genéticos do Brasil
Authors: Antunes Isabella
Published: December 2024

O exame de DNA tem se consolidado como uma ferramenta essencial nas ciências forenses, especialmente na identificação criminal. A genética forense, em particular, fornece informações precisas que são cruciais para a resolução de investigações e confirmação de identidades. Este artigo avalia a efetividade do Banco Nacional de Perfis Genéticos (BNPG) no Brasil, utilizando indicadores de desempenho e comparando-os a métricas internacionais. A análise se baseia em dados dos relatórios semestrais da Rede Integrada de Perfis Genéticos (RIBPG) entre 2017 e 2023, focando em quatro indicadores: taxa de coincidência, índice de retorno, taxa de coincidência entre vestígios e taxa de representatividade criminal. A taxa de coincidência, que indica a probabilidade de correspondência entre perfis, mostrou um crescimento contínuo, embora seja inferior à do Reino Unido, refletindo diferenças nas políticas de coleta e na proporção de perfis cadastrados. O índice de retorno apresentou uma correlação positiva com o aumento de perfis, mas suas limitações dificultaram a avaliação do desempenho. Já a taxa de coincidência de investigação e a taxa de representatividade criminal evidenciam a importância da qualidade da coleta e dos perfis registrados. Os resultados sugerem que, apesar dos avanços, a RIBPG poderia se beneficiar de uma expansão nas políticas de coleta de amostras de referência. A comparação com práticas internacionais oferece subsídios para aprimorar políticas públicas e estratégias de segurança no Brasil, indicando que uma ampliação nas hipóteses de coleta poderia aumentar a resolução de crimes e reduzir a impunidade.
The Boundaries of Gravitational Wave: How Far Could We Reach?
Authors: Nassif Marc
Published: December 2024

Advanced scientific instruments have recently detected gravitational waves, which were predicted by Albert Einstein in his general theory of relativity. Astronomers are afforded a novel method of investigating and comprehending the cosmos because of these ripples in spacetime, which convey information regarding the movements of colossal objects in the universe. Nevertheless, the sensitivity of current detectors, such as LIGO and Virgo, is restricted to a maximum distance of several billion light-years, which limits their detection. Future technological advancements and the development of more sensitive, larger detectors hold the potential to detect gravitational waves from even greater distances in the future, despite this constraint. Scientists aspire to uncover new secrets about our universe and potentially detect gravitational waves from the edge of the observable universe by pushing the boundaries of what is currently feasible.
Posverdad y la época del eco del mundo. Una meditación sobre la experiencia poshumana
Authors: Pac Andrea
Published: December 2024

El trabajo propone una meditación sobre la posverdad, pensada no en contraposición a la verdad sino como la forma que la verdad y las cosas adoptan en la época presente. De esta manera, la posverdad se presenta como una decisión metafísica que articula los modos de existencia posthumana. Esta meditación apela a la reflexión heideggeriana sobre la modernidad (Heidegger, 1958[1939]), así como al análisis de las metáforas básicas de Blumenberg (2008[1997]), las consideraciones de Sadin (2023, 2024) sobre la inteligencia artificial y la noción de no-cosas (Han, 2023). En su recorrido, se nutre de fuentes filosóficas tanto como literarias. Propone que los problemas que plantea la posverdad no son epistémicos sino políticos; pero que, por esa misma razón, la praxis política requiere de una nueva imaginación epistémica y ética.

Parent-Adolescent Conflicts Viewed from Emotional Independence and Parenting Styles
Authors: Vision Vision , Savitri Jane , Tjandraningtyas Jacqueline
Published: December 2024

The level of parent-adolescent conflicts increases after children attain puberty, facilitated by hormonal changes and cognitive development, which are believed to contribute to adolescents developing a sense of emotional autonomy from parents. These changes often lead to parent-adolescent conflicts, facilitating more mature and equal relationships between both parties. Parenting styles in responding to adolescents’ growing need for independence also influence the conflicts. Therefore, this study aimed to investigate the impact of adolescents’ emotional autonomy and parenting styles on the level of conflicts. To achieve this objective, a quantitative study was conducted on 386 Junior and Senior High School students from X Foundation, Denpasar. The results of multiple regression analysis showed that both emotional autonomy and parenting styles significantly impacted parent-adolescent conflicts. The contribution of these variables was more pronounced for mothers (50%) than fathers (43%). Both authoritative and authoritarian parenting styles were found to influence conflicts. Therefore, reducing parent-adolescent conflicts required considering adolescents’ emotional autonomy and fostering authoritative parenting styles.

Published: December 2024

Ten to fifteen percent of mothers worldwide are studied to develop postpartum depression (PPD) following birth. Although studies suggest significant cases among Indonesian mothers in particular, the prevalence remains unknown. Therefore, this study aimed to investigate support needs of mothers and identify the factors that facilitated or hindered social support. A qualitative study was conducted using in-depth interviews, both online and face-to-face. Furthermore, 13 first-time Indonesian mothers who had given birth in the country and were above 18 years old were selected through purposive sampling. The results suggested that facilitating social support actions included validating feelings, sharing responsibilities, assisting with domestic tasks, providing appropriate advice, and exchanging feelings, knowledge, as well as experiences. Hindering factors included partner ignorance, lack of empathy, promotion of irrelevant traditional beliefs, criticism and comparisons, excessive support, and an exclusive focus on the baby. Future studies were further recommended to provide a more comprehensive understanding of the experiences of first-time Indonesian mothers.

Published: December 2024

Research on narrative engagement centers on personal narratives and how these personal narratives challenge master-narratives. Less attention is paid to narrative engagement in an online context, so the current study aims to explore online narrative engagement of master narratives attached to Indonesia’s 30 September Movement. We observed online political discourse by retrieving 3,057 tweets using the keyword “PKI.” We used content analysis to identify relevant themes. Two main themes emerged and represented either support or opposition toward the anti-communist master-narrative. Most tweets in our dataset supported the anti-communist narrative while the remaining were critical of it. We observed that the tweets found predominantly supported anti-communist narratives. Moreover, our research details the unique mechanisms of narrative engagement operative within the online environment. Additionally, we recommend that reconciliation efforts should adopt a subtle approach in challenging the anti-communist narrative to prevent intense opposition.

Published: December 2024

Calcium is a macromineral essential by human body, with deficiencies often leading to bone-related issues. Red snapper bone waste is a source of calcium. The bioavailability of calcium is maximized when present in microscopic particles, such as bio-calcium. This study aims to identify the optimal milling time to produce bio-calcium from red snapper bones, evaluating parameters such as water content, particle size, and yield. Biocalcium was extracted from red snapper bone meal using a 1 N NaOH solution (1:3 ratio) with milling times of 1, 2, and 3 h. Analysis of the red snapper bone meal including yield, particle size, chemical composition, calcium, and phosphorus content. The bio-calcium was characterized based on water content, particle size, yield, Fourier-transform infrared spectroscopy (FTIR), and morphological structure using a scanning electron microscope (SEM). The results demonstrated that a 3-hour milling time yielded bio-calcium with a particle size of 410.8 nm, a water content of 4.51 ± 0.15%, and a yield of 4.12 ± 0.03%. SEM revealed a uniform morphology. FTIR spectra indicated the presence of carbonate, amine, hydrocarbon, and hydroxyl groups, suggesting residual organic substances such as protein, fat, and water. The uniform spectra across all samples highlight the consistency of the extraction process, ensuring a similar chemical composition.

Published: December 2024

Our study focused on unveiling the tropical red algae Gracilaria spp. Active-peptide materials from the central region of Java Island, Indonesia. We described the protein isolation, hydrolysis, purification, and method to test its potency against pathogen Staphylococcus aureus IFO 12576 and Eschericia coli IFO 3301, followed by molecular docking analysis. TCA/acetone precipitation was used to isolate Gracilaria spp. proteins, and the hydrolysis was  done by trypsin digestion with an effective yield to provide antibacterial activity. The disk diffusion method showed promising inhibition and continued with a confirmation test using microdilution, which implied bacteriostatic inhibition with  a minimum concentration of 40 µg/ml, from one potent fraction. Further characterizations were conducted using a proteomic approach. LC-HRMS was used for peptide sequencing in the potent fraction with prospective peptides identified along with its physical properties. Molecular docking simulations  were used to investigate the degree of interactions using binding affinities score (kcal/mol), with the target of receptor DraE adhesin subunit (2JKJ) of Escherichia coli binds chloramphenicol. We proposed the interactions model of peptides GP1 and GP4 against targeted peptides. Our model GP4.1 and GP4.2 model (VVINADAK) were found to have high binding affinities with the energy score of -10,6 and -10,8 kcal/mol, respectively  by the different sites of binding than chloramphenicol succinate.

"Dios" como un término teórico
Authors: Huneeus Alliende Clemente
Published: December 2024

El presente trabajo propone reconsiderar algunas dificultades clásicas relacionadas con la significatividad y referencia de las proposiciones religiosas y explorar la posibilidad de lidiar con ellas bajo la suposición de que ‘Dios’ es un término teórico, es decir, una palabra que nombra una entidad no susceptible de observación directa pero aun así capaz de cumplir un rol explicativo dentro de teorías que pretenden explicar el mundo disponible a nuestra experiencia. La consideración de ciertos rasgos distintivos de los términos teóricos puede arrojar una luz nueva sobre varias temáticas discutidas en la filosofía de la religión contemporánea, especialmente porque entrega un marco nuevo desde el que pensar la naturaleza y funciones de la teología natural.
Some Ruminations on Perfect Theism
Authors: Resto Quiñones Jashiel
Published: December 2024

According to Perfect Being Theism, God is the absolutely perfect (i.e., greatest possible) being. The notion of absolute perfection can be analyzed in different ways. On one interpretation, to be absolutely perfect requires the exemplification of all absolute perfections. On another interpretation, to be perfect requires the exemplification of the best possible combination of perfections. It seems that the latter analysis is better than the former, because it does not fall prey to the problem of incompatible perfections, viz., that there (probably) are perfections that cannot be coexemplified. Here I argue that even if perfect being theists accept the latter analysis, the problem of incompatibility does not go away. I argue that perfections are (probably) incomparable: it is false that some perfection is better than, worse than, or equally good to another perfection. If so, then it is impossible or at least extremely difficult to say that among the combination of perfections there are, there is one that is best among them. I also argue that adopting the former analysis with some restrictions (as Mark Murphy does) leads to the same incompatibility and incomparability problems.

The potential reactions of grafted and ungrafted eggplant plants under different irrigation water levels (100%, 80%, 60% and 40%) with the use of the “conventional and deficit irrigation” and “partial root drying (PRD)” technique were investigated in this study. The research was conducted in a glass greenhouse during two cultivation seasons in 2019 and 2020. Irrigation was applied equally to both grafted and non-grafted eggplant plants using the drip irrigation method. Many observations and measurements were made in the research to determine the reactions of grafted and ungrafted eggplant plants under different irrigation applications. It was found in the study that the method and amount of irrigation water applied had a significant effect on the grafted and ungrafted eggplant plants. In general, grafted eggplant plants were found to have had a higher total yield than the ungrafted plants. However, as the amount of irrigation water applied decreased, the yield also decreased. The advantages of the PRD technique over “conventional and deficit irrigation” have also been revealed. As a result of the research, it could be recommended that the cultivation of grafted eggplant seedlings is more suitable, and irrigation applications could be carried out using the “partial root drying (PRD)” technique.

Nowadays, polymers are widely used in various fields. Such materials often exhibit viscoelastic properties. Engineering analysis considering viscoelasticity is laborious and requires certain expertize. This paper proposes a method for solving linear viscoelastic problems in a simpler way and presents a variant of the solution extension to an anisotropic case. The Volterra correspondence principle allows one to analyze viscoelastic bodies on the basis of the analytical solution like an elastic problem. The developed method is described in a similar way. It allows determining of some functions of time and material constants whose values at a certain point in time can be used as elastic constants. The solutions to these two problems are identical. To substantiate this statement, the authors consider the conditions for maximum equivalence of specific potential energy functionals of strain and stress (for the cases of kinematic and force boundary conditions, respectively) of viscoelastic and reference elastic media. The functions satisfying these conditions have been found, and a new method for solving the problems of linear viscoelasticity of an anisotropic body has been shown using several examples.

The work describes a way to obtain Kahler and sublagrangian submanifolds in real manifolds of arbitrary dimension. For this purpose, the concept of subtwistor and sub-Kahler structure is used. They generalize the classic concepts of twistor and Kahler structures to real manifolds of any dimension with a degenerate fundamental 2-form. The explicit examples of such submanifolds are presented. It is also shown how the subtwis-tor structure on the manifold allows one to factorize locally this manifold into direct products of submanifolds.

The payload launching into Earth orbit is carried out by launch vehicles. At certain stages of the flight, once the dense layers of the atmosphere are passed through, the spent stages of rocket engines and large payload fairings are jettisoned. Falling of separated parts in the designated areas causes economic, environmental, and social problems. This paper presents a mathematical model of the combustion of a pyrotechnic device with a charge-filler from a solid propellant. The model is developed to calculate combustion processes, the flow of the products of combustion and heat and mass exchange in elements of the pyrotechnic device. Calculations are carried out for three configurations of the solid propellant charge-filler. The obtained spatial and temporal distributions of the parameters of occurring flows allow one to assess the feasibility of the pyrotechnic device, namely defragmentation and combustion of the payload fairing elements. The calculated results for the model pyrotechnic device are in satisfactory agreement with experimental data.

When modeling the flow of two-phase media, a number of authors use the kinetic approach. In the 1980s, I.M. Vasenin et al. obtained equations describing the flow of gas and liquid particles based on the equation for a drop distribution function in terms of masses, velocities, temperatures, and intrinsic angular momentum. They differ from the known equations by an additional equation for the mean square of the rotation moment. A numerical solution to the equations shows that due to numerous collisions and coagulation, the rotation moments of some drops exceed the critical value, and the drops are destroyed by centrifugal forces. In this paper, the kinetic approach is extended to the model of a two-phase flow in an axisymmetric de Laval nozzle with account for the radial diffusion of drops under the action of the Magnus force acting on a rotating drop. The system of equations is derived from the kinetic equation up to second-order moments using the method of moments. Only second-order moments, which affect diffusion to the wall, are taken into account. Diffusion leads to an earlier occurrence of drops on the wall and therefore must be considered when profiling the contour of the nozzle.

This paper considers the combustion of high-density propellants with the use of a manometric bomb and a nozzle test facility. The propellant combustion within the manometric bomb is explored at ignition pressures of 18, 50, and 100 MPa. The study results for the propellant combustion in the laboratory nozzle test facility, including a set of nozzles with throat diameters varying from 8 to 20 mm, are presented. The nozzle cluster allows one to adjust the opening pressure up to about 200 MPa. A microwave radar is used to detect the moment of nozzle opening. Some features of the outflow of gunpowder and propellant combustion products are revealed at various geometric dimensions of the nozzle cluster and its opening methods. The laws of propellant combustion along the end face in closed and semi-closed volumes with the gas outflow from a nozzle are obtained. Good agreement is observed in terms of the pressure curve shapes on the ascending and descending branches. The discrepancy in the maximum pressure is less than 5%. The parametric study results for the end combustion of high-density propellants at various nozzle diameters are presented. It is shown that the considered propellants can be used to maintain constant pressure in a semi-closed volume.
