B ← N Lewis Pair Fusion of N,N-Diaryldihydrophenazines: Effect on Structural, Electronic, and Emissive Properties
Authors: Sahoo Ashutosh , Patel Ashvini , Lalancette Roger , Jaekle Frieder
Published: February 2025

Doping of PAHs with boron and/or nitrogen is emerging as a powerful tool to tailor the electronic structure and photophysical properties. As N-doped analogues of anthracene, N,N-dihydrophenazines play important roles as redox mediators, battery materials, luminophores, and photoredox catalysts. While benzannulation has been used successfully as a structural constraint to control the excited state properties, fusion of the N-aryl groups to the phenazine backbone has rarely been explored. Herein, we report the first examples of dihydrophenazines in which the N-aryl groups are fused to the phenazine backbone via B←N Lewis pair formation. This results in structural rigidification, locking the molecules in a bent conformation, while also modulating the electronic structure through molecular polarization. B-N fusion in BNPz1-BNPz3 induces a quinoid resonance structure with significant C-N(py) double bond character and reduces the antiaromatic character of the central pyrazine ring. Borylation also lowers the HOMO/LUMO energies and engenders bathochromic shifts in the emission. Further rigidification in the solid state gives rise to enhanced emission quantum yields, consistent with aggregation-induced emission enhancement (AIEE) observed upon water addition to solutions in THF. The demonstrated structural control and fine-tuning of optoelectronic properties is of great significance to potential application as emissive materials and in photocatalysis.
DIFFERENTIAL ASSOCIATION THEORY OVERVIEW AGAINST CHILDREN OF CRIMINAL ACTS OF TERRORISM
Authors: Kusumawati Aprilia
Published: February 2025

This paper examines children as perpetrators of criminal acts of terrorism and efforts to protect children's rights through a criminological policy approach with focus on the principles and norms of criminal law on the rights of children who are perpetrators of terrorism crimes. This normative juridical research uses a statutory, conceptual, philosophical and case approach. The analysis technique uses prescriptive analysis with logic and legal reasoning. The results of the study show thatthe involvement of children as perpetrators in criminal acts of terrorism is in line with the Differential Association Theory which states that criminal behavior is a learned behavior. In addition, the cause of children becoming perpetrators of acts of terrorism can also be explained through Motivation Theory. There are 2 (two) kinds of motivation, namely intrinsic motivation (internal) and extrinsic motivation (external). Efforts to protect children's human rights as perpetrators of criminal acts of terrorism through the Criminal Policy approach can be carried out with 2 (two) approaches, namely the Penal Policy or efforts to overcome crimes with criminal law and Non-Penal Policies or efforts to overcome crimes outside the criminal law.

Authors: Dwi Kusumawati  , Yunas Derta Luluardi
Published: February 2025

Exploitation of children who are used as beggars is an action that is contrary to one of the rights of children that has been regulated in the constitution or law. The basic rules that serve as guidelines for protecting children's rights are the 1945 Constitution article 28B paragraph (2), the Law on Child Welfare, and the Law on Child Protection. This research was taken from the problems of children who become beggars in Pekalongan Regency. By using empirical juridical research with a statutory approach, conceptual approach and qualitative approach. The results of this research are that the legal protection efforts carried out by the Regional Government of Pekalongan Regency only take the form of handling. There are no basic regulations regarding the protection of children who are used as beggars so no legal action has been provided. So there is a need for regional regulations regarding legal protection for children, especially protection for children who are exploited as beggars, so that it becomes the basis for the government in taking policies to provide legal protection for children who are victims of exploitation.
Farmers' Constitutional Rights and Subsidized Fertilizer: How is the State Responsible?
Authors: Yuwono Nurbaity Prastyananda , Munajad Dias Said
Published: February 2025

Fertilizers play an essential role in increasing agricultural productivity, and Indonesia has implemented a subsidized fertilizer policy since the 1970s to alleviate the burden on farmers and provide fertilizers at affordable prices. However, farmers often face scarcity and difficulties in obtaining subsidized fertilizers, despite their constitutional rights being stipulated in the Minister of Trade Regulation Number 15/MDAG/PER/4/2013 regarding the procurement and distribution of subsidized fertilizers. This research uses an empirical legal method, with primary data obtained through interviews with farmers in Sokoduwet Village, Pekalongan, and secondary data sourced from related documents and literature. Data collection techniques include observation, interviews, and documentation. The study aims to assess the fulfillment of farmers' constitutional rights in obtaining subsidized fertilizers and to understand the legal consequences of fulfilling these rights. The findings indicate that farmers' constitutional rights in Sokoduwet Village have been fairly fulfilled, as subsidized fertilizers help reduce their burden and production costs. However, issues of fertilizer scarcity persist during planting periods, necessitating improvements from distributors and the government to ensure a smoother distribution process. Existing regulations and government decrees have provided farmers with guaranteed rights, including easier access through Farmer Cards and Farmer Identification.

Authors: Kafidhoh Siti , Asyari Nadzif Ali , Ali Mutakin Ali Mutakin , Saujan Iqbal
Published: February 2025

The change in regulations regarding the age limit for marriage in Indonesia is a response to the high rate of child marriage, which still faces various challenges in its implementation. This study examines the debate between tradition and modernity in child marriage practice, the legislative process, and the challenges faced in changing the age limit norms for marriage and marriage dispensation as a legal loophole in enforcing the age limit norms for marriage. The research method employs a normative juridical with statutory and conceptual approaches. The study results show that changes in the age limit norms for marriage aimed to protect children's rights. However, religious norms and social pressure influence its implementation through marriage dispensation in the Religious Court, resulting in inconsistencies in its law enforcement. This condition poses a challenge to harmonize religious norms with social change. This study emphasizes the need for a more transparent and strict marriage dispensation mechanism. In addition, increasing public legal awareness is the key to encouraging social changes that support child protection. Strengthening public awareness and consistent regulations is expected to minimize and suppress the number of child marriages.
EXPLORING PETASE: A PROMISING ENZYME FOR PLASTIC WASTE MANAGEMENT
Authors: Vidya A.S
Published: February 2025

Plastic pollution is a pressing global challenge owing to the pervasive, near-unmanageable threat it poses to living and non-living systems and the environmental stress it causes. The widespread use of plastic materials, their slow degradation rates, and their ability to travel vast distances through air and water currents have made plastic waste a significant environmental challenge. Plastics are classified as degradable and non-degradable ones based on their extent of degradation in natural environments. Conventional plastics, have an extremely slow degradation rate in the environments. Degradation of plastics by environmental microbes are fast, eco-friendly and minimises pollution. This study focuses on role of PETase in PET plastic degradation. Conventional methods such as photochemical, thermal are employed. Biological method using microbes provide greener solutions. Mutagenesis of marine hydrocarbonoclastic bacterium Pseudomonas aestusnigri showed PET degrading potential. The Ideonella sakaiensis mutant showed 3-fold increase in PET degradation compared to wild type. Two strains C. reinhardtii CC-124 and CC-503 degraded PET completely to terephthalic acid detected using HPLC. The in vitro technique of plastic degradation does not fit industrial applications. Thus, genetically engineered microorganisms combined with plastic-degrading enzymes would be a possible for practical application.

Published: February 2025

The eyelid is unique in that it contains tissues of very diverse origins in a small volume. All these tissues can degenerate malignantly or benignly, with the majority being benign. Orbito-palpebral tumors are characterized by histological diversity due to the architectural complexity of the orbito-palpebral region. Our study consists of an epidemiological, histological, therapeutic and evolutionary analysis of these carcinomas through a retrospective study extending over a period from September 2022 to March-September 2024, including 27 patients with eyelid tumors operated on in the Department of Plastic, Reconstructive and Aesthetic Surgery, Burns Center, CHU Tanger-Tétouan-Al Hoceima. Our patients ranged in age from 17 to 84 years, with an average age of 60.11 years and a clear male predominance. Rural origin was represented (68.75%), and the majority had been exposed to the sun. All regions of the eyelid were affected, with a concentration of lesions in the lower eyelid (62.96%). Basal cell carcinoma was the most frequent histological type (75%), followed by adenoid cystic carcinoma (18.75%).

Authors: Lamia Chakib  , Mohamed Ijim  , Oussama Fikri  , Lamyae Amro
Published: February 2025

Pulmonary fibrosis is a rare manifestation of systemic lupus erythematosus (SLE), occurring in 3 to 9% of cases, and is rarely the initial presenting symptom of the disease. Its pathophysiology remains poorly understood, and its clinical and radiological presentation resembles that of other connective tissue diseases. It is often associated with multi-organ involvement.

The article presents the case of a 64-year-old woman with no significant medical history, hospitalized for stage III dyspnea (according to Sadoul), dry cough, and fatigue, all evolving over six years. Her medical history revealed photosensitivity and inflammatory polyarthralgia of the large joints. Biological tests showed an inflammatory syndrome, leukopenia, and positive antinuclear and anti-DNA antibodies, which led to the diagnosis of systemic lupus erythematosus (SLE) based on the ACR criteria (photosensitivity, lymphopenia, positive antinuclear antibodies, and positive anti-DNA antibodies).

Imaging studies (chest X-ray and CT scan) revealed bilateral diffuse pulmonary fibrosis, with a honeycomb appearance and thickening of the septal lines. Pulmonary function tests showed a restrictive syndrome. The diagnosis of pulmonary fibrosis associated with SLE was confirmed. The patient was treated with corticosteroids and an immunosuppressant, with stable disease progression.

In summary, this case illustrates the complexity of diagnosing pulmonary fibrosis in the context of systemic lupus erythematosus, a rare but serious condition that requires a multi-faceted approach to management.

Published: February 2025

Introduction: Bovine Tuberculosis (bTB) is a significant zoonotic disease that affects the human population and livestock globally. In Zambia, bTB poses substantial economic and social challenges to livestock farmers.

Aim: The purpose of this study was to assess the impact of Bovine Tuberculosis on the social-economic status of livestock farmers.

Methodology: The study was qualitative and quantitative in nature and concurrent triangulation design guided the study. The study had 280 participants who were selected through heterogeneous purposive sampling. The production of data was through semi-structured interviews, structured questionnaires, and document analysis. Quantitative data analysis was performed in R software, while qualitative data was analyzed using Nvivo® and content analysis.

Findings: The results revealed that there was a significantly high impact of bTB on monthly income (p< 0.001, OR = 0.99, CI = 0.997-0.998). For every 0.99 odds of a decrease in monthly income, the impact from bTB increased, an indication of a reduction of monthly income resulting from the high impact of bTB. Our results also indicated that for every one-unit increase in monthly income, the log of the odds associated with low milk production decreased by 3.38. Therefore, the more income generated from milk sales the lesser milk production incurred. The results revealed that there was a significantly high impact of bTB on monthly income (p< 0.001, OR = 0.99, CI = 0.997-0.998). For every 0.99 odds of a decrease in monthly income, the impact from bTB increased, an indication of a reduction of monthly income resulting from the high impact of bTB. Further, participants were faced with carcass contamination at abattoirs. They suggested that the government working together with other stakeholders should initiate an insurance scheme to cover livestock. However, the contributions should be minimal. Finally, participants reported having experienced social-economic discriminatory statutes, as they were not rendered eligible to be part of cooperatives where they would borrow money for empowerment (surety) due to losing of source of income (animal) at an abattoir

Published: February 2025

This study examines public sentiment and key topics in Twitter discussions regarding the COVID-19 vaccine and the Omicron variant in the US and Indonesia. The importance of this research lies in understanding people's changing views on vaccination, especially in light of new virus variants. Using sentiment analysis with VADER and topic modeling with Latent Dirichlet Allocation (LDA), this research analyzes 637,367 tweets from the US and 91,679 tweets from Indonesia collected over two months from January 21 to February 21, 2022. The results reveal that US discussions on vaccines are predominantly positive, while those on Omicron are mostly negative. In contrast, discussions in Indonesia are largely neutral, followed by positive sentiment. Additionally, five main topics were identified for each country, with the US showing a broader range of vaccine-related discussions. These findings suggest that while the vaccine is seen as a source of hope in both countries, factors such as literacy, socioeconomic status, and education contribute to negative sentiment and vaccine resistance.
ENGLISH PRONUNCIATION IN EGYPTIAN EFL CLASSROOMS: ATTITUDES, CHALLENGES, AND EXPECTATIONS
Authors:   University of Szeged and Cairo University, Faculty of Arts, Abdelreheem Hasnaa Hasan Sultan
Published: February 2025

This paper is an effort to explore issues pertaining to pronunciation instruction in Egypt, from the perspective of Egyptian EFL learners and teachers, with an emphasis placed on: views on pronunciation performances, expectations from their lecturers/students and study programmes, challenges faced in learning/teaching English pronunciation, desired proficiency standards and attitudes towards English and the specific items taught, the influence of mother tongue, as well as views on what participants would like to see applied in textbooks and classrooms (e.g. organised activities, behaviour, approaches, methods, etc.). Recommendations based on questionnaire responses by both learners and teachers can be summarised as follows: (i) ensuring the qualifiedness of teachers, lecturers and educators in general (e.g. by seeking a TEFL-related qualification alongside a relevant university degree as position requirements), (ii) teaching English in English for more exposure to the target language content, (iii) minimising teacher-centered classroom performance and allocating most of the class time for student participation and involvement, (iv) directing efforts towards creating an engaging and motivating environment for both teachers and learners by refraining from employing traditional outdated teaching methods that may lead to eliminating chances of effective communicative interaction, (v) applying assessment methods that prioritise development over scores to enhance students’ creativity and critical thinking skills, (vi) integrating the element of pronunciation in the teaching of other language skills, (vii) ensuring the cultural appropriacy and appeal of the study materials to meet the expectations of learners, address the actual teaching/learning objectives and suit the particular EFL context in question.
A Beta Mixture Model for Careless Respondent Detection in Visual Analogue Scale Data
Authors: Zhang Lijin , Domingue Benjamin , Vogelsmeier Leonie V. D. E. , Ulitzsch Esther
Published: February 2025

Visual Analogue Scales (VASs) are increasingly popular in psychological, social, andmedical research. However, VASs can also be more demanding for respondents, potentiallyleading to quicker disengagement and a higher risk of careless responding. Existing mixturemodeling approaches for careless response detection have so far only been available forLikert-type and unbounded continuous data but have not been tailored to VAS data. Thisstudy introduces and evaluates a model-based approach specifically designed to detect andaccount for careless respondents in VAS data. To this end, we integrate existingmeasurement models for VASs (Noel and Dauvier, 2007) with mixture item response theorymodels for identifying and modeling careless responding. Simulation results show that the proposed model effectively detects careless responding and recovers key parameters, and highlights the unsuitability of the existing mixture factor analysis model for VAS data. Weillustrate the model’s potential for identifying and accounting for careless responding usingreal data from both VASs and Likert scales. First, we show how the model can be used tocompare careless responding across different scale types, revealing a slightly higherproportion of careless respondents in VAS compared to Likert scale data. Second, wedemonstrate that item parameters from the proposed model, accounting for carelessresponding, exhibit improved psychometric properties compared to those from a modelthat ignores it. These findings underscore the model’s potential to enhance data quality byidentifying and addressing careless responding.
Psychological Insights on the Fans’ Boycott of the 2022 FIFA World Cup
Authors: Bertin Paul , Grippa Pauline
Published: February 2025

The 2022 FIFA World Cup in Qatar has been criticised for numerous social, political, and environmental issues. While an important call to boycott the tournament spread worldwide, research has yet to document the motives underlying a boycott of such a mega sporting event. We investigated fans’ intentions to boycott the 2022 FIFA World Cup in four countries of the Francophonie engaged in the World Cup (N = 1,635). We found that being highly identified with the team and enjoying football for aesthetic pleasures predicted rejection of the boycott, while the most robust predictor of boycott intentions was a concern for environmental issues. When assessing actual boycott behaviours among fans after the World Cup (N = 286), we found a significant decrease compared to boycott intentions. Importantly, this intention–behaviour gap was true even for politicised fans with high awareness of social and environmental issues who initially planned to boycott the tournament. We discuss the paradox of calls to boycott mega sporting events: Unlike other consumption products, these events often have no alternatives, which influences fans’ decisions not to boycott. As a consequence, boycott behaviours mirror one’s fandom rather than political values, and boycotters are those barely interested in these events in any case.
Knowledge and Practices of Hairdressers about Occupational Safety and Health in Kaski District
Authors: Gopal Prasad Sedhai
Published: February 2025

Hairdressers are exposed to various occupational hazards, including physical, chemical, and biological risks, which can lead to skin disorders, respiratory issues, and communicable diseases. This cross-sectional study assessed the knowledge and practices of hairdressers regarding occupational safety and health (OSH) in Kaski district, Nepal. A total of 60 salon workers from urban and rural areas were surveyed using a semi-structured questionnaire and direct observations. The findings revealed a satisfactory level of OSH awareness overall, with urban workers demonstrating significantly higher awareness compared to their rural counterparts. Most participants (83.3%) acknowledged the role of contaminated tools in spreading skin diseases, and 96.7% identified razors as potential sources of contamination. However, gaps in the use of personal protective equipment (PPE) and adherence to hygiene practices were observed, particularly among rural workers. Musculoskeletal disorders (MSDs) were prevalent due to prolonged standing and repetitive motions, highlighting the need for ergonomic training. Furthermore, the study emphasized the importance of training and education in improving OSH practices, as workers with formal training exhibited better safety practices. The findings align with global research, underscoring the urgent need for targeted interventions, stricter regulations, and comprehensive training programs to enhance workplace safety and health in the hairdressing profession. Future research should explore the long-term impacts of these measures to promote a safer working environment.

Motavita Formation, new lithostratigraphic unit in the central region of the Eastern Cordillera, Colombia
Authors: Terraza Melo Roberto , Martínez Aparicio Germán
Published: February 2025

Se propone formalmente una nueva unidad litoestratigráfica para el Cretácico superior en la región central de la Cordillera Oriental de Colombia denominada Formación Motavita, constituida por cherts, porcelanitas, lodolitas, limolitas y cuarzoarenitas subordinadas, con niveles de abundantes foraminíferos bentónicos de la familia Siphogenerinoididae y capas de fosfatos potencialmente explotables. La cartografía geológica adelantada por el Servicio Geológico Colombiano (SGC) en los últimos 20 años, soportada con bioestratigrafía de amonitas y la correlación de secciones estratigráficas, permitió inferir importantes cambios litológicos laterales en la base del Grupo Guadalupe, desde los cerros orientales de Bogotá, donde dominan las arenitas (Formación Arenisca Dura), hasta el municipio de Motavita, donde prevalecen las rocas finogranulares silíceas de la nueva Formación Motavita propuesta. La sección tipo de la nueva Formación Motavita corresponde a un estratotipo compuesto conformado por un holoestratotipo y un paraestratotipo. En el holoestratotipo del Alto del Gavilán (municipio de Motavita) aparece el límite inferior con la infrayacente Formación Conejo del Santoniano superior. En el paraestratotipo de la cantera La Batea (municipio de Samacá), se observa el límite superior con la suprayacente Formación Plaeners del Campaniano superior. La nueva Formación Motavita sustituye a la “Formación Plaeners” de Renzoni (1967) y de Etayo (1968a, b) y a la “Formación Lidita Superior” de Montoya y Reyes (2003a, 2005). El intervalo cronoestratigráfico va del Santoniano superior al Campaniano inferior, siendo predominantemente del Campaniano inferior. Regionalmente, se puede reconocer desde el norte de Nemocón (departamento de Cundinamarca) hasta los municipios de Tasco y Paz del Río en el departamento de Boyacá.

We show new geodetic velocity field for Western Venezuela based on repeated GNSS campaign measurements in 2011, 2013, and 2016. The 28 sites are distributed on the northern side of the Oca-Ancon fault, the eastern Maracaibo Block, and vicinities to the whole extension of the Boconó fault but particularly densified across the La Grita segment in the Southern Mérida Andes. Deformation in western Venezuela based on geodetic measurements has been the object of recent studies, however this contribution focuses on the Southern Merida Andes. We assess the simple homogeneous model for one fault (across La Grita segment of the Boconó fault) and two-faults (Boconó fault and a secondary system) model. Our preferred model of both approaches shows a far-field velocity of 11.3 mm yr-1 and a 9.6 km locking depth for the Boconó fault. Nonetheless, the best fit concerning the two-fault model shows a slip rate of 9.5 mm yr-1 for the Boconó fault and 1.3 mm yr-1 for the Caparo fault. We confirm that the Boconó fault is the main structure that accommodates most of the right-lateral slip between the Maracaibo block and South American plate. A complimentary comparison with the surface velocity model VEMOS17 indicates the need of densifying observation sites through measurement campaigns and continuous GNSS stations. These stations will improve our knowledge of local and regional geodynamics and their implications for seismic hazard studies.

Objective: This study evaluated the impact of agricultural backyard production on the well-being of producing families in the context of food security in a Microregion of Chicontepec Veracruz, Mexico, highlighting the substantial economic advantages of this practice.
Design/methodology/approach: Through probabilistic sampling, a structured survey on availability, accessibility, and nutrition was designed and applied to backyard-producing families. A multinomial logistic regression model was employed to analyze the relationship between a dependent variable and a set of independent variables.
Results: In the microregion of study, backyard production is distributed in 55.4% of fruit trees, 25.4% of regional crops, and 19.2% of vegetables. The two crops that add the most to the basic basket are corn and Chichimeken beans. 98% of producers estimate that backyard production (livestock and agriculture) saves the family economy 10% to 50% of its costs.
Limitations on study/implications: Knowledge of the backyard production of the microregion under study will allow the development of municipal policies that will link producers with the local market.
Findings/conclusions: Backyard production has been shown to contribute significantly to food security since different fruit trees, vegetables, and local crops substantially contribute to the household economy through sales and self-consumption.

Espacio educativo límite. El patrimonio como contenido revolucionario en educación
Authors: De Castro Martín Pablo
Published: February 2025

Este artículo explora el concepto de educación patrimonial como un territorio de frontera, un límite difuso que permite la transgresión y la aventura en la aplicación de acciones educativas en torno a los bienes culturales, ya sean materiales o inmateriales. El espacio liminar de la educación en torno al acervo cultural habilita la subversión y la interpretación del currículo, al tiempo que da cabida a la transdisciplina/interdisciplina como un activo fundamental para el éxito de los proyectos de innovación en educación patrimonial. Entre los terrenos expuestos con más claridad, se hace referencia a la intuición educativa como guía en el proceso de diseño de las acciones o a la propia voluntad del educador, en un fiero compromiso por sostener su posición central en todo el proceso de enseñanza-aprendizaje. Así mismo, se transita por el aprendizaje y servicio, las metodologías artísticas, la investigación basada en las artes como algunas de las herramientas metodológicas más apropiadas para desenvolverse en el vasto y difuso territorio patrimonial, o para abordar patrimonios controvertidos. Todos estos aspectos aparecen brevemente ejemplificados a través de proyectos de excelencia educativa en el campo de la educación en torno al patrimonio.
