Authors: Ramli Muhamad Zakwan Hamizan , Lee Tien Tien
Published: December 2024

Penguasaan konsep asas Kimia yang lemah dan sifat abstrak konsep Kimia menyebabkan pelajar sukar untuk menentukan garam terlarutkan dan garam tak terlarutkan. Kajian ini bertujuan menilai keberkesanan permainan Salt-UNO Card terhadap pencapaian konsep Garam dan minat pelajar tingkatan empat dalam pembelajaran Kimia. Pendekatan kuantitatif dengan reka bentuk kuasi eksperimen telah dipilih untuk menjawab persoalan dan hipotesis kajian. Seramai 63 orang pelajar dari sebuah sekolah menengah di daerah Alor Setar telah terlibat sebagai sampel kajian. Seramai 32 orang pelajar diletakkan dalam kumpulan kawalan manakala baki 31 orang pelajar sebagai kumpulan rawatan. Ujian Pencapaian dan Soal Selidik Minat telah digunakan sebagai instrumen kajian bagi mengukur tahap pencapaian dan minat pelajar dalam pembelajaran Kimia. Dapatan kajian dianalisis menggunakan ujian-t bagi membuat perbandingan min skor antara kedua-dua kumpulan. Keputusan analisis ujian-t sampel bebas menunjukkan terdapat perbezaan yang signifikan (t = -6.40, p < 0.05) dalam min skor pascaujian pencapaian antara kumpulan kawalan dan rawatan. Namun, tidak terdapat perbezaan yang signifikan (t = -0.66, p > 0.05) dalam min skor pasca minat antara kumpulan kawalan dan rawatan. Kesimpulannya, permainan Salt-UNO Card berkesan terhadap pencapaian konsep Garam pelajar berbanding kaedah pengajaran konvensional. Walau bagaimanapun, dapatan kajian menunjukkan bahawa permainan Salt-UNO Card kurang berkesan terhadap minat pelajar dalam pembelajaran Kimia. Implikasi kajian menunjukkan bahawa permainan Salt-UNO Card dapat dijadikan sebagai bahan bantu mengajar yang sesuai dalam membantu meningkatkan kefahaman, penguasaan dan pencapaian pelajar terhadap konsep Garam.

Published: December 2024

Algebraic ability is crucial for students to master; however, studies have shown that many students struggle with learning algebra. In the Malaysian context, there is a lack of specific instruments to measure the algebraic ability of 13-year-old or 7th grade students. This study aims to develop a valid and reliable instrument to measure the algebraic thinking ability of 7th grade students in Malaysia. The Algebraic Thinking Ability Test (ATAT) assessment utilized the Winsteps Rasch Measurement Model. Fifteen main question items were selected, each further divided into subsections and treated as individual items, resulting in a total of twenty-seven items. These items were adapted and modified from the Form One or 7th grade Mathematics Textbook and TIMSS Mathematics questions. Each item had a different rating scale; thus, the Partial Credit Model (Group 0) was applied for analysis. The newly developed instrument was administered to 93 students from government schools in Selangor, Malaysia. The results indicated that the Algebra Test adequately described students' ability in algebra; however, the students' ability was found to be exceptionally low in this study. In other words, the respondents demonstrated lower capability as a group than the item difficulty. Overall, this research contributes to the development of a reliable and valid instrument to measure the algebraic ability of 7th grade students in Malaysia. The findings highlight the need for targeted interventions and support to improve students' algebraic thinking skills in the Malaysian education system.
Social Security and Compensation: Analyzing the Protection of Fixed-Term Employment Contract Workers under the Omnibus Law on Job Creation
Authors: Deviona Ayu Anggi , Sriono Sriono , Siahaan Nimrot
Published: December 2024

This study aims to analyze the legal protection afforded to fixed-term employment contract workers under Law Number 6 of 2023, which introduces significant changes to the legal framework governing fixed-term employment in Indonesia. Focusing on working conditions and compensation, this research employs a normative legal research method with a statute approach and utilizes qualitative analysis with a content analysis approach. The findings reveal that Law Number 6 of 2023 establishes a new paradigm in protecting fixed-term employment contract workers by affirming their right to wages during probationary periods, providing flexibility in contract renewals, and regulating the provision of compensation. However, implementing this Omnibus Law also presents new dynamics and challenges, such as the potential for job insecurity due to excessive flexibility in contract extensions. A case simulation further exposes the gap between legal norms and the reality on the ground, where some companies still neglect their obligation to compensate fixed-term employment contract workers. These findings underscore the urgent need for commitment and active participation from all stakeholders, including the government, companies, and workers, in realizing harmonious, productive, and equitable industrial relations.

El objetivo de esta esta investigación es analizar cómo las micro y pequeñas empresas (Mypes) de H. Matamoros, Tamaulipas, adoptan prácticas de Responsabilidad Social Corporativa (RSC) y cómo el género del directivo influye en su aplicación. Para lograrlo, se llevó a cabo un estudio cuantitativo basado en encuestas aplicadas a 389 Mypes, con el apoyo de estudiantes, y se incluyeron empresas de los sectores industrial, comercial y de servicios. La mayoría de las empresas se comprometen activamente a respetar los derechos humanos, prevenir la contaminación y promover el bienestar de sus empleados. No obstante, el desarrollo comunitario se presenta como un área que requiere mayor atención, ya que una proporción significativa de las empresas reconoce que su contribución en este ámbito es limitada. En cuanto a la influencia del género, los directivos masculinos muestran mayor compromiso en áreas como el respeto a los derechos humanos y la responsabilidad hacia los clientes. Por su parte, las mujeres destacan en la prevención de la contaminación. Estos hallazgos sugieren que considerar el género en el liderazgo puede fortalecer las iniciativas de RSC en las Mypes.

Published: November 2024

A floresta amazônica, a maior do mundo e uma das áreas de maior biodiversidade, desempenha um papel fundamental no ciclo climático global. Estudos sobre a evapotranspiração nessa região são essenciais para entender sua influência nesse ciclo. O presente trabalho teve como objetivo avaliar diferentes métodos de estimativa da evapotranspiração (ETo), comparando-os ao método de Penman-Monteith (PM), considerado padrão, utilizando cenários futuros do IPCC. Além disso, foram desenvolvidos scripts práticos em R para o cálculo da Eto. A área de estudo foi a Floresta Estadual do Antimary. Para a estimativa da ETo, utilizando tanto o método padrão (PM) quanto os métodos alternativos Irmak 1 e 2, Alex e Hargreaves-Samani, foram empregados dados de temperatura mínima e máxima do ar, precipitação e velocidade do vento. As estimativas foram realizadas tanto para o período de referência (1969-2021) quanto para cenários futuros (2021-2100) baseados nos SSPs do IPCC: SSP 1-2.6, SSP 2-4.5, SSP 3-7.0 e SSP 5-8.5. Os scripts desenvolvidos no RStudio permitiram o cálculo da ETo por meio dos diferentes métodos, além de análises estatísticas comparativas. As estimativas de ETo pelo método PM foram menores no cenário SSP 1-2.6, com um valor de 67,83 mm d⁻¹, e maiores no SSP 5-8.5, com 68,80 mm d⁻¹. O método Irmak 2 apresentou a maior correlação com o método PM, com valores de correlação variando entre 0,997 e 0,999, e erro padrão de estimativa (EPE) de 0,018 mm d⁻¹ a 0,027 mm d⁻¹ em todos os períodos analisados. Todos os métodos alternativos avaliados demonstraram boas correlações com o PM, sendo adequados para estimativas de ETo na região da Floresta Estadual do Antimary.

Published: November 2024

O desenvolvimento de material didático é crucial para facilitar o processo de ensino e aprendizagem, tornando os conteúdos mais acessíveis e compreensíveis para os alunos. Nesse sentido, desenvolvemos um modelo 3D de um Tiranossauro rex/ Tyrannosaurus rex (Osborn, 1905), com o objetivo de explorar a extinção em massa de animais antigos por eventos naturais e estabelecer sua relação com a diversidade atual, a fim de facilitar a compreensão da extinção da biodiversidade, integrando conceitos de ecologia e a importância da preservação ambiental. Confeccionamos o T. rex utilizando materiais de baixo custo e recicláveis, aplicando técnicas de modelagem. Posteriormente, o modelo foi exposto para a turma do 2º ano do Técnico em Meio Ambiente integrado ao Ensino Médio do IF Goiano – Campus Ceres, na disciplina de Ecologia, e fizemos uma apresentação teórica que abordou a história da extinção e sua relevância contemporânea. Esperamos que o uso desse material didático tenha promovido maior engajamento dos alunos e possibilitado uma discussão aprofundada sobre a biodiversidade, suas ameaças e a necessidade de conservação. Além disso, esperamos que esse exemplar tenha sido uma ferramenta eficaz no ensino de ecologia, contribuindo para a sensibilização sobre a extinção e a importância da conservação da biodiversidade nos dias atuais.

“Nibezwe kodwa ningabalaleli” – An Analysis of Hidden Treasures in African Literature
Authors: Dladla Celimpilo Piety
Published: December 2024

This study critically explored African literature, focusing on the creative strategies 19th-century authors employed to resist censorship of African literary expression. The paper addresses the prevalent criticisms of African literature by examining Nyembezi’s novel “Inkinsela YaseMgungundlovu,” translated as “The Richman of Pietermaritzburg,” by Sandile Ngidi. The research highlighted the pivotal role of annotations in uncovering implicit societal constructs shaped by historical limitations within South African literature. Through a qualitative desktop study, this paper systematically analysed selected passages from the novel, employing monolingual and bilingual dictionaries along with scholarly literature to extract deeper meanings. The findings underscored how annotations bridge linguistic and cultural gaps, enriching readers’ understanding of the socio-political contexts embedded in the text. Additionally, the study advocates for the re-evaluation of African ethnic literature and encourages greater engagement among scholars and readers. It further posits that annotations enhance translation by providing crucial contextual information, empowering target readers to engage with the text as intended by its original audience. Ultimately, this research illuminates the hidden treasures within African literature, promoting its broader significance in literary studies and advocating for future analyses that reveal the rich cultural heritage of its people.

Exploring the Perspectives of Women on Unreported Experiences of Gender-Based Violence in South African Homes (Relationships)
Authors: Ntshangase Mohammed X. , Molise Habasisa V
Published: December 2024

In many areas of South Africa, gender-based violence has continued to grow, and during COVID-19 lockdowns, it reached its highest heights. This study sought to differentiate between active gender-based violence and passive gender-based violence, as this distinction has always been ignored both in literature and in the South African legal system. While active gender-based violence (GBV) gets reported to the police and legally addressed, passive GBV happens in closets and cannot be reported. However, passive GBV leaves no physical scars that can be presented in court and is therefore not addressed in South African law. Semi-structured interviews were conducted with a purposively sampled group of 10 women from Vhembe District (Venda), and thematic analysis was adopted. This study argued for women’s psychological health to be equally recognized as well as their physical health. The core argument is that depression causes as much harm as physical scars. The findings of the study revealed that GBV offenses as omissions in relationships do affect South African women in serious ways, similar to those offenses reported as commission. The findings also showed that South African law only focuses on GBV by commission; this is because GBV by omission offenses have nowhere to report and no one investigates them. Furthermore, the study found that women in South Africa suffer from being victims of mental health problems due to the fact that they live with unreportable offenses of GBV by omission. Therefore, the study contends that cases of GBV by commission in the context of spouses are usually the end result of salient GBV by omission that has been happening for a long time with no ability to report or call for intervention. This study adds to the growing literature on combating GBV in South Africa.

The impact of innovation and renewable energy on CO2 emission in Asian developing countries
Authors: Pham Xuan Truong , Nguyen Cam Nhung , Nguyen Thi An Ly
Published: November 2024

This study examines the impact of innovation and renewable energy on CO2 emissions in a sample of 15 developing Asian countries from 2000 to 2020. Using panel data regression analysis, it identifies two key findings. First, innovation - measured by research and development (R&D) expenditures and the number of patents - leads to an increase in CO2 emissions, likely driven by the scale effect, whereby economic growth and technological advancements initially result in higher emissions. Second, a higher share of renewable energy consumption significantly reduces emissions, underscoring the critical role of clean energy in mitigating environmental impacts. The findings also support the Environmental Kuznets Curve (EKC) hypothesis, suggesting that as income levels rise, emissions initially grow but eventually decline as economies transition toward greener technologies. Additionally, the study highlights population growth and afforestation as significant factors influencing CO2 emissions. By offering empirical evidence, this research provides valuable guidance for policymakers in developing Asian nations, emphasizing the need to balance innovation with greater investments in renewable energy to achieve sustainable development and lower carbon emissions.​

Mindfulness, Kindergarten, and Mobile Applications
Authors: Anagnostopoulou Panagiota , Drigas Athanasios
Published: December 2024

The following review explores the use of mobile applications in mindfulness practices. Also, it examines the fundamental characteristics of mobile applications that might enhance their effectiveness. This study is the third and final phase of a project that aims to investigate the advantages of technology and mindfulness in kindergarten. In the first two parts, we examined the use of social robots and virtual reality in mindfulness interventions. The objective of this paper is to present existing research on mobile applications and mindfulness, evaluate the possible advantages and obstacles of combining these two fields, and also analyze the features of the apps that lead to optimal results. We conducted a bibliographic review of articles. The results of our study indicate that mindfulness applications have a substantial impact on the development of children’s mindfulness abilities, such as their ability to regulate attention and manage emotions, while also enhancing their general well-being. Advances in mobile technology provide opportunities to overcome barriers to traditional mindfulness training because they are portable devices that are also cost-effective. According to our findings, the apps should be age-appropriate, simple, and engaging. However, there is limited empirical evidence supporting the efficacy of many available mindfulness apps. We need further research to explore and validate their effectiveness, especially in comparison to traditional in-person interventions.

Tributaires de l’héritage laissé par les images de la fin du Moyen Âge, la vieille femme décharnée aux seins flétris et l’homme obèse, chauve et impotent répondent ainsi à des stéréotypes bien définis. Dès la fin du xve siècle néanmoins, les artistes germaniques s’approprient littéralement ces deux corps extrêmes et repensent complètement leurs usages symboliques, esthétiques et formels, apportant de la sorte une contribution majeure à l’histoire culturelle de la laideur et des corps hors norme. Parmi eux, Albrecht Dürer n’a pas seulement tenté l’expérience inédite de construire un corps extrême normatif, il a fourni un cadre théorique à l’idée d’une beauté multiple, qui rend compte de la variété et du développement biologique des corps. Dans cette perspective, l’article montre comment, dans l’art germanique de la Renaissance, l’obésité et la maigreur vieillissante se sont imposées comme des objections efficaces au modèle canonique des corps à l’antique, dont le caractère subversif s’inscrit dans la problématique culturelle de la concurrence avec l’Italie.
« L’intime est politique. » Les corps malades féminins chez Jo Spence et Hannah Wilke
Authors: Lévy Léna
Published: December 2024

À travers l’étude des œuvres ultimes de Jo Spence et Hannah Wilke, produites alors qu’elles sont toutes deux atteintes d’un cancer, le présent article porte sur les enjeux de la représentation des corps féminins souffrants en histoire de l’art, dans le contexte sociopolitique occidental de la fin du xxe siècle. Leurs œuvres relèvent d’une perspective féministe au sens où elles remettent en cause les modèles esthétiques et historiques des représentations et s’inscrivent dans une histoire collective de la revendication d’une visibilité du féminin s’éloignant des stéréotypes pour prendre en compte le monstrueux, l’anormal, l’informe ou l’obscène. En parallèle des mouvements féministes, des mouvements de santé et des questionnements sociologiques sur la place de la maladie et de la mort dans les sociétés occidentales, le travail autopathographique de ces artistes femmes interroge la place des corps malades, à l’extrémité de la vie, dans l’histoire de l’art et l’histoire politique.
Na Génese da Primeira Crónica Portuguesa
Authors: Miranda José Carlos
Published: December 2024

Após a recente publicação de Afonso Henriques e a Primeira Crónica Portuguesa, por Filipe Moreira, o panorama da historiografia em Portugal no séc. XIII deverá ser totalmente revisto, e com ele muito do que sobre a sociedade, a produção escrita e o uso da língua desta época se dava como adquirido. Mas questões centrais sobre a "Primeira Crónica Portuguesa" permanecem por resolver, tais como as fontes que utilizou, os propósitos a que a sua redacção obedeceu e seu processo de elaboração. O presente estudo propõe-se equacionar alguns desses aspectos, chamando a atenção para o modo como o texto se relaciona com várias obras provenientes de Castela, em particular com o Chronicon Mundi, de Lucas de Tuy.
Google is the new Mickey Mouse (and Cognitive Science of Religion still isn’t clear about what a god is)
Authors: Campos Veronica
Published: December 2024

In a 2008 paper, Justin Barrett outlined five conditions meant to be jointly sufficient for an agent-concept to elicit faith and religious commitment. In other words, he outlined five requirements for an entity to be a god. His table of criteria was intended as a solution to the so-called Mickey Mouse problem, the problem of explaining why people believe in god(s), but not in other entities, such as Mickey Mouse. Barrett was criticized in a 2010 paper by Gervais & Henrich, who claimed the table yields false positives: some god-concepts meet all five criteria but are not the object of faith and religious commitment, such as Zeus, as well as any god-concepts of every extinct religion. In this paper, I argue along similar lines, but beyond. I show that some of the false positives Barrett’s table allows for don’t even stand for gods of any genuine religion, extinct or not.

Lifestyle choices significantly shape the intricate chemical makeup of the human body, impacting health and lifespan. The use of bio-chemical adsorbents in multistage potable water filtration represents a major breakthrough in addressing global water quality challenges. The fundamentals of bio-chemical adsorbents are discussed, distinguishing between bio-based and chemical materials and highlighting various types such as activated carbon, biochar, and graphene oxide. The concept of multistage filtration systems is introduced by major advantages over single-stage systems and key design considerations. The chapter then delves into the applications of bio-chemical adsorbents in water purification, presenting case studies and comparative analyses with traditional methods to demonstrate their efficacy and performance metrics. Strategies to enhance adsorption efficiency through surface modifications, hybrid systems, and composite materials are explored in detail with targets on environmental impact, sustainability, regulatory standards, and future trends on bio-chemical adsorbents.

Published: November 2024

This chapter reports on how private Islamic centres in Singapore promote religious education with the help of technology. This research study relies on the method of content analysis of textbooks used in the Islamic centres. Two research findings are noted in this chapter. First, the Islamic textbooks incorporate various technological tools and resources to impart religiosity in students. Secondly, technology has its limitations in engendering religiosity through effective teacher guidance and moral development. A major implication of this study is that educational changes in Islamic education need to be underpinned and mediated by an Islamic worldview on knowledge, education and morals.

Authors: Bouras Christos John , Kollia Anastasia
Published: November 2024

5G has almost arrived, and the demands imposed by mobile subscribers gradually augment in terms of network performance, coverage, and efficiency. Thus, the frequencies that are already available do not adequately cover the users' needs. In this context, Milimeter Wave technology (mmWave) appears as one of the 5G key enablers, as the unused and available spectrum of 30-300GHz (mmWave) could be redefined in order to cover several issues that have appeared concerning bandwidth. The mmWave band is almost unused, and as a result, it could cover future demands and network users. In this paper, the mmWave is analyzed in a techno-economic way. What is more, mathematical models for the costing of mmWave are developed. Parameters for the models are opted. Sensitivity Analysis (SA) experiments contribute to indicating the most fundamental network parameters and costs concerning the mmWave and the bandwidth in general. Conclusions are summarized and future research is suggested.
