Migration, Remittances, And Child Growth: Evidence From Cambodia, Vatana Chea, Patcharawalai Wongboonsin

Journal of Demography

Remittances have become a main resource for development in low- and middle-income countries around the world. With impressive growth in remittances over the decades comes interest in their importance to development. Using data from the 2009 Cambodian Socio-Economic Survey with a sample of 2,767 children under 5 years of age, this study investigates the impact of migration and of remittances on children's quality of health, and tests whether or not the so-called permanent income hypothesis holds for remittances relative to other income. Also employed is two-stage least squares analysis to account for potential endogeneity problems. In short, it was found …

Effects Of Ball Milling Duration And Sintering Temperature On Mechanical Alloying Fe3si, Varistha Chobpattana, Chakansin Phoomkong, Peerawat Nutnual, Kritsada Thaengthong, Wanchai Pijitrojana

Journal of Metals, Materials and Minerals

Fe3Si is under interest as a ferromagnetic electrode of magnetic tunneling junctions (MTJs). Its crystalline structure is important for achieving high device efficiency. This work focuses on mechanical alloying of 3:1 ratio of 99% pure Fe and Si powder mixtures by ball milling and sintering. The mixtures were ball-milled for various durations up to 20 h. Then, they were sintered from 400°C  to 800°C for 4 h in Ar.  SEM images and particle size analysis show significant reduction in average particle size of the mixtures after ball milling for 20 h. The longer duration of ball milling process promotes powder …

(R2165) Two Different Stages With Two Distinct Harvesting Processes, S. Vijaya, Krishika M

Applications and Applied Mathematics: An International Journal (AAM)

This study extends the classical Lotka-Volterra prey-predator model by incorporating a stage structured prey population consisting of juvenile and adult stages, while considering a single predator species governed by a Holling type II functional response. The growth of the juvenile prey depends on the adult prey population and since the juvenile prey has no reproduction capability. Two distinct harvesting strategies are introduced in the model. Constant-yield harvesting is applied to the juvenile stage of the prey population and represents a fixed amount of harvest regardless of population size. Constant effort harvesting is applied to the adult stage of the prey …

The Moderating Role Of Coping Strategies In The Relationship Between Depressive Symptoms And Hypersexuality Among Young Filipino Adults, Kathryn H. Jacob, Voltaire M. Marquez

Makara Human Behavior Studies in Asia

Mental health among young adults is receiving increasing attention because of its significant influence on overall well-being, including physical health, interpersonal relationships, and daily functioning. Among the key concerns within this age group are depression and hypersexuality. This study investigated the moderating role of coping strategies in the relationship between depressive symptoms and hypersexuality. We hypothesize that adaptive coping strategies—such as problem- and emotion-focused coping—would attenuate the negative effects of depressive symptoms on hypersexual behavior, whereas avoidant coping would intensify this relationship. To test these assumptions, a cross-sectional explanatory study was conducted involving 407 Filipino young adults aged 18 to …

Sanctuary: Counter-Oppressive Relationships With Farmed Animals As An Ecopsychological Imperative, Kelsey Bomboy

The International Journal of Ecopsychology (IJE)

Consumers are intentionally shielded from and often misled about the process of breeding, raising, and slaughtering animals for consumption. By confining most farmed animals to warehouses in rural areas while the majority of humans are sequestered in urban areas, we have effectively created a world where humans do not have to contend with the sense of interconnectedness that arises when witnessing and being witnessed by a farmed animal. Within industrial slaughterhouses, the physical act of killing is minimized to just a fraction of the workers, so that even those who are responsible for rendering a once living being will never …

From Uncertainty To Dialogue: Visualising Collaborative Noticing And Mathematical Intuitions In Students' Narratives Within Probability Learning, Daniela Diaz-Rojas

The Mathematics Enthusiast

This study explores the critical role of language and communication in fostering collaborative noticing practices that display mathematical intuitions within probability learning. Through an analysis of student interactions, I show how the joint articulation of ideas and the exploration of shared doubt enable intuition, often perceived as an object that is held and a solitary experience, to become a socially shared and co-constructed process. The observed collaborative dialogue concerns shared content and form, constructing a joint narrative architecture that enables common understanding and allows the group to notice, examine, and reshape their intuitions. Collaborative noticing when working with probability problems …

Journal of Marine Science and Technology–Taiwan

The shipboard safety management system (SMS) is designed to enhance safe operations, risk management, and emergency response to improve overall ship safety and efficiency. This paper demonstrates the use of an engine room simulator (ERS) for collecting failure modes and applies it to a comprehensive failure analysis of the stern tube lubricating oil system. A new risk closeness coefficient method was developed, integrating expert background knowledge and weighted risk assessments. The analysis, based on multiple expert evaluations, covered five subsystems, eight main components, 23 failure modes, and 112 failure causes. This study presents 26 recommendations for maritime practitioners and onboard …

Port And Vessel Communication Traffic Intrusion Detection: A Variational Autoencoder‑Enhanced Multilayer Perceptron Approach, Chien-Lin Chiang, Hsien-Cheng Chou, Ming-Yuan Peng, Yi-Yuan Chiang, Yu-Shun Liu

Journal of Marine Science and Technology–Taiwan

Port and vessel networks increasingly operate on IP/Ethernet backbones with high‑noise, high‑dimensional traffic. We present a lightweight hybrid intrusion‑detection model that couples a variational autoencoder (VAE) with a multilayer perceptron (MLP) and augments training with a boundary‑oriented latent‑space mixup strategy. The VAE models the distribution of normal traffic and identifies anomalies through reconstruction errors. Subsequently, it generates robust latent vectors, enabling the MLP to perform highly accurate supervised classification. On the UNSW‑NB15 dataset, the proposed pipeline attains ≥97% accuracy and an outstanding recall of 99.56% in binary intrusion detection, and visualization of the latent space (PCA) together with reconstruction‑error analyses …

Sar Ship Detection Based On Shallow Feature Guidance, Chenxu Xia, Peng Chen, Ya Zhang, Ying Li

Journal of Marine Science and Technology–Taiwan

Maritime ship detection is of great significance for both military security and civilian applications. Synthetic Aperture Radar (SAR), with its all-weather and all-day imaging capability, plays a vital role in maritime surveillance. Nevertheless, SAR ship targets typically appear small in scale, embedded in complex backgrounds, blurred at boundaries, and easily confused with near-shore features, which pose substantial challenges for accurate detection. To address these issues, we propose a SAR ship detection network that integrates dual enhancements of small-object representation and edge information. The network introduces two key components: the Small Target Refine Pyramid (STRP) to strengthen shallow feature representation for …

Contributions To Research On Preservice And Inservice Science Education And The Current Status Of Initial Science Teacher Education, David F. Treagust, Michelle De Kok

Australian Journal of Teacher Education

In this paper, firstly we review Australian university science educators’ contributions to the Australian Journal of Teacher Education. These publications demonstrate a wide range of interesting and targeted initiatives to enhance the teaching and learning science by preservice and inservice teachers.  Secondly, we examine the current situation of initial teacher education programs and development for future possibilities of science teacher education in Australia. This analysis shows that attention has concentrated disproportionately on entry standards and the theory-versus-practice tensions, while the conditions shaping retention, workload, and equitable subject-matter staffing remain substantially unaddressed.

Affective Governmentality And Feeling The Cycle Of Crisis: Why Teacher Education Reform In 21st-Century Australia Has No End, Brad Gobby, Barry Down

Australian Journal of Teacher Education

This article uses affect theory to critically examine the discourses underlying initial teacher education (ITE) reform in 21^st century Australia. We argue that contemporary ITE reform has persisted in the face of a quarter-century of scholarly critique not because that critique is wrong, but because reform operates through an affective governmentality, a regime in which the conduct of conduct is accomplished through the organisation of affect as well as the application of knowledge and technique. In this domain of reform, the public shaming of teachers and teacher educators, and the promise of evidence-based “rigour” compose a recurring cycle of …

The Story Of Indigenous Teacher Education In Western Australia, Mindy Oxenburgh, Rhonda Oliver, Helen Cd Mccarthy

Australian Journal of Teacher Education

Since colonisation, the history of Indigenous education and related teacher education in Western Australia (WA) has been fraught. It has involved a mixture of inherent prejudice, blatant racism, ignorance, valiant attempts to redress the balance, optimism, and fluctuating success. There remains a need for more Indigenous and especially local teachers who understand their students’ cultural and linguistic needs and who can best serve as the link between addressing these needs, their community’s desires and the reality of the students' schooling. The employment of non-Indigenous and non-local teachers is problematic at several levels and, as a result, over the past 50 …

A Systematic Review Of Alkali-Treated Polylactic Acid Biocomposites Relevant To Pineapple Leaf And Water Hyacinth Hybrid Design, Muhammad Rizky Adrianto Subandi, Tri Hartutuk Ningsih, Hanna Zakiyya

Journal of Mechanical Engineering Science and Technology (JMEST)

The increasing demand for sustainable materials has accelerated the development of biodegradable polymer composites. Polylactic acid (PLA)-based natural fiber composites have attracted significant attention due to their renewable characteristics; however, their performance remains limited by weak fiber–matrix compatibility, moisture sensitivity, and inconsistent interfacial behavior. Alkali treatment has been widely applied to modify lignocellulosic fibers by removing non-cellulosic components and improving surface characteristics, although its effectiveness remains dependent on treatment conditions and fiber properties. This systematic review evaluates the influence of alkali treatment on PLA-based natural fiber composites and assesses the available evidence supporting future pineapple leaf fiber (PALF) and water …

Otogenic Temporomandibular Joint Involvement With Intracranial Inflammatory Changes In A Child, Lacy Jones, Jessica Bloom-Foster

Journal of Maine Medical Center

Introduction: Temporomandibular joint (TMJ) involvement is an uncommon but potentially important complication of pediatric otologic infection. Imaging findings may overlap with septic arthritis, mastoiditis, and intracranial inflammatory extension, creating uncertainty regarding the need for invasive intervention.
Clinical Findings: A 12-year-old female with recurrent otitis externa presented with 3 days of severe right otalgia, progressive facial and periauricular swelling, jaw pain, and trismus. Her examination results showed marked external auditory canal edema and tenderness that initially prevented visualization of the tympanic membrane.
Clinical Course: She was treated with intravenous ceftazidime and clindamycin, and initially improved; however, her facial swelling …

Do Cows Dream Of Open Fields?: Moral Imagination In The Age Of Industrial Meat, Josefa Benasso Barriga

Caroliniana Undergraduate Research Journal

This paper examines the ethical complexities of industrial meat production through the lens of competing moral frameworks, including utilitarianism and deontological ethics. While industrial agriculture provides affordable food and supports global economies, it also raises significant concerns regarding animal welfare, public health, environmental sustainability, and labor conditions. Using the BSE crisis as a case study, the analysis highlights how efficiency-driven systems can obscure moral perception and normalize harmful practices. The paper further explores the role of language and moral psychology in sustaining these systems, particularly through mechanisms such as moral distancing and cognitive dissonance.

By situating animal ethics within broader …

The Mechanical Actor: Meyerhold’S Biomechanics And The Birth Of The Analyzable Body, Margaret R. Davisson

Caroliniana Undergraduate Research Journal

This paper analyzes Vsevolod Meyerhold’s system of biomechanics, an actor-training system, as a theatrical framework that participated in the broader cultural consolidation of an analytical conception of human movement also taking place within modern scientific biomechanics. Situating Meyerhold’s work within the industrial and ideological context of early twentieth-century Soviet modernity, the study examines how theatrical training methods operationalized emerging assumptions about the mechanization, decomposition, and optimization of human movement. Through comparative analysis of Meyerholdian performance theory and scientific biomechanics, the paper demonstrates a structural correspondence between theatrical movement segmentation and biomechanical concepts such as kinematics, force distribution, and mechanical equilibrium. …

Impacts Of Acetaminophen Treatment On Hl-60 Cell Viability, Differentiation, And Apoptosis, Emma Crenshaw, Shannon Finney, Todd Mount, Gabriela M. Ramirez, Harshita Negi, Charles Andrew Schumpert

Caroliniana Undergraduate Research Journal

Acetaminophen is a widely used analgesic and antipyretic, but its effects on cancer cell behavior remain unclear. This study examined the effects of low concentrations of acetaminophen on HL-60 leukemia cells, focusing on cell viability, apoptosis, and differentiation. HL-60 cells were treated with 33 nM and 66 nM acetaminophen for 1-hour and 24-hour periods. Cell viability and density were assessed using a Trypan Blue Viability Assay, apoptosis was measured using a Caspase-Glo 3/7 Assay, and morphological changes were analyzed by May-Grünwald Giemsa Staining. Results showed decreased cell viability and density with increased apoptosis in a dose-dependent manner, with the stronger …
