The Political Economy of Digital Technology
Authors: Huato Julio
Published: April 2024

The world is undergoing a profound revolution in the technical conditions of production due to the rapid buildup and pervasive use of digital machinery. It constitutes a radical transformation in the scale and mode of labor cooperation in the reproduction of our lives. As with any other technological development under the rule of capital, the fruits of labor cooperation are expropriated from the workers and weaponized against them as vehicles of class exploitation, capital accumulation, imperialist domination, and militarism. Three ideologies accompany this revolution in capitalist production: disembodied technology, technological determinism, and the fear of the rebellious machines. Socialists face the challenge of appropriating and redirecting technology, turning it into a means of radical liberation and socialist construction.

Published: April 2024

Decolonization of history education mainly seeks to decenter Eurocentric narrative in history curriculum and teaching. Whilst this topic has been widely explored, the discussion related to the decolonization of history education has yet to be explored. This research aims to trace the complex process of decolonization of the history curriculum in Indonesia, which took place at the beginning of its independence, and how the political situation might have influenced this process. Historical research was conducted. Archival materials were obtained from various institutions both in Indonesia and overseas. The data were analyzed and interpreted using decolonization as a framework. This research found that the Indonesian government has tried to decolonize the history curriculum by foregrounding the role of Indonesians in History. However, the effort was not easy because the references used in teaching were still written using sources from the colonial period. Moreover, this research shows that political changes could affect the history curriculum.Dekolonisasi pendidikan sejarah terutama berupaya untuk menghilangkan narasi Eurosentris dalam kurikulum dan pengajaran sejarah. Meskipun topik ini sudah banyak dieksplorasi, namun pembahasan terkait dekolonisasi pendidikan sejarah masih belum tereksplorasi. Penelitian ini bertujuan untuk menelusuri kompleksnya proses dekolonisasi kurikulum sejarah di Indonesia yang terjadi pada awal kemerdekaannya, dan bagaimana situasi politik mempengaruhi proses tersebut. Penelitian sejarah dilakukan. Bahan arsip diperoleh dari berbagai institusi baik di Indonesia maupun di luar negeri. Data dianalisis dan diinterpretasikan dengan menggunakan kerangka dekolonisasi. Penelitian ini menemukan bahwa pemerintah Indonesia telah mencoba mendekolonisasi kurikulum sejarah dengan mengedepankan peran masyarakat Indonesia dalam Sejarah. Namun upaya tersebut tidak mudah karena referensi yang digunakan dalam pengajaran masih ditulis menggunakan sumber-sumber dari masa kolonial. Selain itu, penelitian ini menunjukkan bahwa perubahan politik dapat mempengaruhi kurikulum sejarah.
Incidencia política comunitaria en la Feria de Agricultores de Barranca, Puntarenas, Costa Rica, en el 2023
Authors: Bolaños Alvarado Bayron , Cascante Chaves Magally
Published: April 2024

This article presents a case study on the citizen participation strategies implemented by farmers from Barranca, Puntarenas, during 2023, to resolve the conflict stemming from the eviction of their Farmers’ Market in 2020. The closure of this commercial space had serious negative economic and social consequences for producers and the community. The analysis of the political and legislative process helped us identify the strategies used by farmers to actively engage in finding a viable solution to the problem. These tactics included presenting a bill in the Legislative Assembly and exerting constant pressure on deputies, which resulted in the approval of the legislation that facilitated the return of the farmers’ market to the original facilities. The study assessed the effectiveness of these context-specific participatory strategies in influencing concrete results. Findings offer valuable lessons on localized ways of citizen participation in the formal political sphere, aiming to promote more inclusive democracies geared towards collective well-being.

Authors: Kasmani Jafar Ebrahimpour , Samariha Ahmad , Margavi Mohammadreza Amiri
Published: April 2024

Nanofibrillated cellulose (NFC) and its combined usage with cationic starch and a cationic copolymer of acrylamide were studied in relation to the properties of paper. Independent pulp treatments using additives separately included 0%, 5%, 10%, and 15% refined long fiber pulp, 3 and 6% NFC, 0.75 and 1.5% cationic starch and 0.07% and 0.15% cationic polyacrylamide and combined treatments. Handsheets were made of the above treatments, and finally their optical and microscopic properties were evaluated. Increasing the NFC content to 6% increased the brightness and yellowness of the white liner by 13% and 21%, respectively. The liner opacity was also reduced by 1%. Additionally, increasing NFC by 6% compared to imported long fibers, the brightness and yellowness of the white liner increased 5.44% and 6.3%, respectively. The liner opacity was also reduced by 1%. A 1.5% cationic starch addition to NFC increased the brightness of the white liner by 4.4%, its whiteness increased 1.5%, and its yellowness increased 2.1%. The opacity of the liner was also reduced by 7.1%. The use of NFC and cationic starch can improve the optical properties of the white liner, while imported long fibers may be problematic.

Authors: Aldy Fithria , Yanni Gema Nazri , Siregar Jelita
Published: April 2024

Myopia is the most common ophthalmic condition worldwide, with an estimated 22.9% of the population or 1.406 billion people affected. Studies of candidate gene-associated refraction abnormalities have also identified several genes that cause vulnerability myopia, including the hepatocyte growth factor (HGF) and  hepatocyte growth factor receptor (MET) genes. The purpose of the study was to analyze the correlation between hepatocyte growth factor (HGF) levels, degrees of myopia, and long axial in adolescents with myopia treated as outpatients in Universitas Sumatera Utara Hospital. This study applied the cross-sectional analytical approach. The inclusion criterion for the participants was patients diagnosed as suffering from myopia by the Ophthalmology Outpatient Clinic of the Universitas Sumatera Utara Hospital. Sampling was performed consecutively with a minimum sample size of 25 patients in control group and 25 patients in the case group. This study revealed that the mean axial length of the right eye in the case group was 23.82 mm, with a significant difference in the axial length between the case and control groups. The mean HGF level in the myopia group was 510.49 ng/mL, which was not significantly different from the mean HGF level in the control or emmetropic group. The HGF levels were highest in the group of subjects with moderate myopia, with an average of 551.87 ng/mL, and differences in HGF levels were identified in different degrees of myopia. Thus, no significant correlation is identified between the HGF levels, axial length, and myopia degree.

In Ukraine, there is an urgent need to regulate the powers, grounds, and methods of using unmanned aircraft by the security and defense forces, as well as to improve enforceability of the procedure for its use.Purpose. To defi ne the conceptual framework for the use of unmanned aerial systems in the protection of the state border of Ukraine and the ways to improve the relevant regulatory framework of Ukraine.Material and Methods. General scholarly research and special methods have been employed, the main of whichare logical-semantic, system-structural, historical, observation, and comparison.Results. The history of implementation, problems and promising areas of use of unmanned aerial systems inthe protection of the state border have been studied. Attention has been drawn to the rapid development of unmanned technologies, which leads to their widespread use on the battlefi eld and in law enforcement. Emphasis has been placed on analyzing the negative trends in increasing number of violations related to the use of unmanned aerial vehicles.Conclusions. The research has proved the need to improve the classifi cation of unmanned aerial vehicles, as defined by NATO standards and EU regulations, given the possibility and necessity of using the same-type unmanned aerial vehicles in the military, law enforcement, and civilian spheres. It is necessary to put into operation nationwide digital platforms for drone control, which can perform almost all tasks previously performed exclusively by manned aircraft.
Euonymus nanus (Celastraceae) in Europe and in the Caucasus Mountains: geographi-cal distribution, habitats and modern state of populations
Authors: Melnyk V. , Shynder O. , Didenko S. , Savchuk L.
Published: April 2024

The study of the current state of populations and habitats of rare and threatened species of plants is a relevant task of ecological research. The paper presents the results of investigation of the geographical distribution, habitats and modern state of populations of a rare species of the European and Caucasian floras Euonymus nanus M. Bieb. (Celastraceae), included in the Red Data Books of Ukraine, Moldova, the Russian Federation and the Red List of Romania. The structure of the European and Caucasian parts of its range is described. The natural range of Euonymus nanus includes Romania (the Carpathian Mountains and the Moldavian Plateau), Moldova (the Moldavian Plateau and Southern Podillia Upland), Ukraine (Podillia and Dnieper Uplands and Dnieper Lowlands, Crimean Mountains) and the Russian Federation (North Caucasus). There are near 100 localities of E. nanus in Europe and 6 localities in the Caucasus Mountains. A phytocoenotical peculiarity of European habitats of E. nanus is their confinement exclusively to deciduous forests. This is their difference from Caucasian habitats, connected with scree slopes and from Asiatic habitats, connected with coniferous forests. Biogeographical and paleontological data and some biological peculiarities of E. nanus (low reproductive potential) confirm its relic nature (Tertiary relic) in Europe. The claim that E. nanus has an alien origin in Europe is insufficiently scientifically substantiated. The current state of E. nanus populations in Europe and in the Caucasus Mountains is shown. Known local populations of E. nanus are few in number, with relatively low densities, and their gradual decline is observed everywhere. Due to the uniqueness of E. nanus populations, it must be included to the European Red List. Modelling of E. nanus populations in cultivated coenoses is an effective method of ex situ conservation for this species.

QOS in Wireless Sensor Network-Fault Tolerance and Efficient Bandwidth Allocation
Authors: Naik Deepa
Published: April 2024

Wireless sensor networks are an integral part of Industrial Revolution 4.0. The traffic efficiency of any network depends on link failures and available bandwidth. This paper discusses route discovery in case of a link failure and a control system approach for efficient bandwidth allocation. Control system approach has been attempted to address the twin issues of link failure and bandwidth allocation. The main function of Wireless networks is to gather information about various types of parameters, notably process variables in industries, air quality variables in ambient air monitoring, weather forecasting, cyclonic alertness, congestion and other parameters in traffic routing. The outputs from WSN are feed into Plant systems either to display or control the variables. Naturally for efficient, reliable display and control of parameters continuous supply of information from WSN to Plant systems is important. Hence improving Quality of Service Parameters like signal to noise ratio, fault tolerance, Band width allocation, and stability and load balancing is vital while designing a WSN. We discuss about two QOS parameters in WSN namely Fault Tolerance in case of Link failures and Efficient Bandwidth Allocation. Links here are wireless in nature.

Authors: Chen Jieh-Haur , Utami Andina Mugi , Wang Jui-Pin , Huang Chien-Ming , Shen Lian
Published: April 2024

This study aims to develop a preference ranking model using the analytic hierarchy process (AHP) for expanding tap water utilities. The literature review identifies six aspects and 15 factors influencing the prioritisation and decisions regarding the extension of tap water pipelines. A pilot study involving eight officials in Taiwan yielded a consistency index (CI) of 0.070, which is below the threshold of 0.1, supporting the feasibility of the AHP questionnaire. The formal AHP questionnaire, targeting 30 officials with over 6 years of work experience, resulted in a CI of 0.062 and a consistency ratio of 0.050, both meeting the criterion of being less than 0.1. The established priority ranking places emphasis on (a) aspects – water source > construction period > population > residential type > political matter > constructability – and (b) factor preference rankings within each aspect. The outcome undergoes evaluation based on 26 empirical cases to determine its potential approval by the central government. Apart from the costly construction in the top three cases, the acceptance rate sees an approximately 60% increase compared with previous rates. These findings promise to enhance operational efficiency, saving both time and manpower in practical applications.
Effects of Gender and Age on Performance in Verbal Fluency and Working Memory Measures Among Cognitively Healthy Korean Adults
Authors:   RehabilitationInternational Korea, Koh Hyojeong , Paek Eun Jin , Sung Jee Eun
Published: April 2024

The purpose of this study is to examine how gender and aging affect verbal fluency performance
depending on the task types and how their performance is associated with working memory
capacity in cognitively healthy Korean adults. A total of 120 normal adults (60 males and 60
females) residing in Korea, matched for age and education, were categorized into three age
groups: younger (20-39 years), middle-aged (40-59 years), and older adults (60-79 years). Verbal
fluency was assessed using semantic and verb fluency tasks. Working memory was evaluated
through digit span tasks. Significant gender-related differences were found in verbal fluency
tasks, with females consistently outperforming males in all tasks, particularly semantic fluency.
Moreover, a noticeable decline in performance on verbal fluency tasks is observed among the
different age groups, with young adults displaying the highest performance, followed by
middle-aged and older adults. Remarkably, the interplay between task type and gender emphasizes that females excel in semantic fluency across all age groups. In younger and older groups, the
fluency task that best distinguishes gender was the verb fluency task, and a significant correlation
was observed between working memory and all verbal fluency tasks in male and female groups.
These findings suggest that males may face challenges in specific verbal fluency tasks compared
to females, potentially influenced by various factors and complex interactions.
Negros na piscina: as imagens de felicidade e insurgência como estratégias decoloniais
Authors:   Universidade Federal de Pernambuco, MORAES Fabiana
Published: April 2024

Valorizadas tanto no jornalismo quanto na arte, as imagens de sofrimento não podem ser vistas somente como denúncias da desumanização de pessoas, grupos e povos: a repetição das mesmas pode, ela mesma, provocar esta desumanização. Isso porque não se publicizam as formas de criatividade e autonomia vitais e existentes mesmo entre os minorizados socialmente. É com essa premissa que trazemos, como parte de uma investigação maior, uma análise sobre os trabalhos de três fotógrafas e um fotógrafo (Ana Araújo, Bárbara Wagner, Gessica Amorim e Walter Firmo) cujos trabalhos, que não negam os constrangimentos diários de seus fotografados, também refletem beleza e resistência, expressões vitais do poder.

Las diferencias entre el giro decolonial en Comunicación y la Crítica Comunicacional Latinoamericana son sustanciales pero no por ello antitéticas. El presente ensayo problematiza en tres dimensiones esta divergencia: la primera discute por qué la Comunicación-Decolonialidad no puede problematizarse como una teoría en el sentido clásico; la segunda dimensión, aborda algunas diferencias conceptuales y programáticas entre la Comunicación-Decolonialidad y la Crítica Comunicacional Latinoamericana; y la tercera, explora los asuntos de conocimiento y (re) conocimiento a los que apunta el giro Comunicación-Decolonialidad como una otra epistemología.
La parentalidad en las familias latinoamericanas tras la migración: una revisión sistemática de factores de riesgo y factores de protección de Nauzet
Authors: Gutiérrez Rodríguez Nauzet , Álvarez Lorenzo Míriam , Rodrigo López María José
Published: April 2024

Objetivo: Esta revisión pretende identificar los factores de riesgo y protección que influyen en la parentalidad de las familias latinoamericanas tras migrar hacia los dos principales países receptores de población latina, Estados Unidos y España. Metodología: Se ha realizado una revisión sistemática de artículos científicos a través del protocolo PRISMA (2000-2020). Se incluyeron 17 estudios publicados entre 2006-2019 sobre el ejercicio de la parentalidad de familias latinoamericanas migrantes en ambos países. Resultados: Se han identificado múltiples factores de riesgo y protección procedentes de diferentes ecosistemas relacionados con la parentalidad. Los factores sociodemográficos como la precariedad económica y laboral fueron los factores de riesgo más documentados y se relacionaron con el estrés parental y los estilos educativos inadecuados. Los factores del microsistema, como los estilos y creencias autoritarias de los/as padres/madres y a falta de afecto, se relacionaron con una mayor probabilidad de problemas conductuales disruptivos en los/as hijos/as. Los factores procedentes del exosistema, como la ausencia de apoyos, se relacionaron con un mayor aislamiento social y menor integración comunitaria. Los factores del macrosistema como la aculturación se relacionaron con mayor estrés parental y una percepción más baja de la competencia parental. Los factores protectores se encontraron mayoritariamente en el microsistema (ej., apego) y en el exosistema (ej., apoyo social). Conclusiones: La migración no es en sí misma negativa o positiva para el ejercicio de la tarea parental, sino que son los factores de riesgo y protección en el nuevo ecosistema los que dificultan o favorecen dicho ejercicio. Las políticas sociales y las intervenciones dirigidas a familias migrantes latinoamericanas deben diseñarse considerando el impacto de los diferentes factores de riesgo y protección en la dinámica familiar.

Published: April 2024

In parallel with the rapid advancement of technology, the increasing use of smartphones causes some problems. "Nomophobia", which refers to the state of being away from the cell phone or having connection problems, is one of these problems. The aim of this study is to examine whether the level of nomophobia of academicians teaching at a university located in the west of Türkiye differs significantly in terms of age, gender, academic title and marital status variables. The sample of the study consisted of 205 academicians working at the university who voluntarily participated in the study. In the data collection process of the study, a questionnaire was used to determine the level of nomophobia. Data analysis of the study was carried out using independent sample t-test and analysis of variance test. The results of the analysis revealed that there was no statistically significant difference between the participants' general nomophobia levels and nomophobia dimensions in terms of gender, marital status and academic title variables, while there was a significant difference between the categories of age variable. Considering the findings of the study, it can be said that it is very important to understand how nomophobia questionnaire scores differ according to demographic characteristics in order to increase the efficiency and effectiveness of academicians and to develop new strategies in this direction.
Interaction of 6-Bromo- and 6-Chloro-Ubiquinone derivatives with mitochondrial electron transfer system
Authors: Chang-An Yu , Xiao-long Li , Lian-Quan Gu , Linda Yu
Published: April 2024

To understand the reaction mechanism of quinone-mediated electron transfer, a series of ubiquinone (Q)-derivatives with a bromine or chlorine atom at the 6-position and a different alkyl side chains at the 5-position of the benzoquinone ring were synthesized and characterized. The chemical properties and electron transfer activities were compared with the native ubiquinone, Q0C10. The redox midpoint potential of 6-Bromo- and 6-chloro-Q derivatives is 142 mV and 148 mV, respectively. These 6-halo-Q derivatives are reducible by ascorbate alone or by succinate in the presence of succinate-ubiquinone reductase. The reduced 6-halo-Q (6-halo-QH2) can be oxidized by cytochrome c alone or via ubiquinol-cytochrome c reductase. In the presence of cytochrome c oxidase and cytochrome c, 6-halo-QH2 is oxidizable by oxygen. 6-Halo-Q derivatives are reducible by succinate via succinate-ubiquinone reductase. They function as an electron-mediator connecting succinate-Q reductase and cytochrome c oxidase and bypass ubiquinol-cytochrome c reductase in the mitochondrial electron-transfer chain. This bypassing results in a decrease in energy coupling efficiency and a lower P/O ratio. These compounds might have therapeutic value in treating diseases that are caused by the oversupply of energy.

In this section, generate nuclear coordinates on thehigh-resolution H&E images through color deconvolution and identificationof two-dimensional intensity minimums in the hematoxylin channels of the images(corresponding to the dark blue nuclei). This calculation is done on thehigh-resolution tiff images saved inside pth10x. Note on cell detection: It is important that the cellcoordinates are generated on unregistered images, as warping caused by theregisteration process can cause inaccuracies in nuclear detection performed onthe registered images. Instead, detect coordinates on the unregistered images,then apply the registration transformations to the cell coordinates todetermine their positions in registered space.

This study develops a new higher-order shear deformation theory (HSDT) to analyze the static behavior of functionally graded (FG) beams under various mechanical loading conditions. The new theory is meticulously designed to effectively represent complexities in stress, strain, and deformation analysis, with a focus on maintaining or enhancing accuracy while reducing the computational burden for practical applications. The material properties of the FG beams are assumed to vary continuously across the thickness as per a power law distribution (P-FGM). The governing equilibrium equations are derived using the principle of virtual work. Navier’s solution method is then utilized to obtain the analytical solutions. Extensive numerical studies are conducted to study the influences of key geometric and material parameters on the static response. The deflection, axial stress and tangential stress distributions are computed for different combinations of length-to- thickness ratio, material grading index, and applied loads. The results are validated by comparison with existing literature where good agreement is observed, demonstrating the accuracy of the proposed HSDT formulation. Parametric analyses provide useful insights into the individual and coupled effects of beam slenderness, material inhomogeneity and transverse loading on the static performance of P-FGM beams. This study enhances understanding of the structural behavior of FG beams through an efficient and accurate analytical approach.

Bonding between asphalt layers is a crucial factor affecting the durability and mechanical response of flexible pavements. The effect of tack coat application on this bonding has been extensively studied, with several factors influencing the degree of bonding achieved. These include the type of tack coat, application rate, temperature, and moisture, among others. This study evaluated the effect of binder type and application rate on the interface shear strength of bituminous layers made of asphalt concrete type MDC-19, using the Laboratorio de Caminos de Barcelona (LCB) shear test. Two types of asphalt emulsions, CRL-1 and CRL-1hm (conventional and modified with polymers, respectively), were used as tack coats at five residual application rates. The results of the study showed that the CRL-1hm tack coat developed a higher shear strength than the CRL-1 tack coat. Additionally, there was a variation in strength with an increase in application rate, leading to the determination of an optimum rate. These findings demonstrate the importance of binder type and application rate in achieving optimal bonding between asphalt layers, with potential benefits for the longevity and performance of pavements. Overall, this research provides valuable insights for pavement engineers seeking to optimize the bonding between asphalt layers. The study highlights the potential of modified emulsions, such as CRL-1hm, and the importance of carefully considering the application rate to achieve the desired bonding performance.

Background: Moringa peregrina is widely used in the traditional medicine of the Arabian Peninsula to treat various ailments, because it has many pharmacologically active components with several therapeutic effects. Objective: This study aimed to investigate the inhibitory effect of Moringa peregrina seed ethanolic extract (MPSE) against key enzymes involved in human pathologies, such as angiogenesis (thymidine phosphorylase), diabetes (α-glucosidase), and idiopathic intracranial hypertension (carbonic anhydrase). In addition, the anticancer properties were tested against the SH-SY5Y(human neuroblastoma). Results: MPSE extract significantly inhibited α-glucosidase, thymidine phosphorylase, and carbonic anhydrase with half-maximal inhibitory concentrations (IC50) values of 303.1 ± 1.3, 471.30 ± 0.3, and 271.30 ± 5.1 µg/mL, respectively. Furthermore, the antiproliferative effect of the MPSE was observed on the SH-SY5Y cancer cell line with IC50 values of 55.1 µg/mL. Conclusions: MPSE has interesting inhibitory capacities against key enzymes and human neuroblastoma cancer cell line.
