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 …

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 …

Journal of Health Research

Background: Sleep disturbances impact cognition and physiology. While individual essential oils are documented, a gap remains in how multi-component blends can target multiple pathways. This study evaluated a blended essential oil (BEO) systematically guided by Thai Traditional medicine (TTM) principles to balance the "Wind" element (Tard Lom) alongside modern neurobiological validation.

Methods: A one-group pretest–posttest quasi-experimental study was conducted in adults (aged ≥ 20 years, n = 38) with sleep disturbances (PSQI > 5). The BEO formulation consisting of orange (2.5% w/w), lavender (1.0% w/w), ylang-ylang (1.5% w/w), geranium (0.5% w/w), cedarwood (2.0% w/w), and rosewood (2.0% w/w) in 95% ethanol …

The Role Of Family Problem-Solving And Neighborhood Social Cohesion On Child Socioemotional Learning Among Families With Low-Income, Nazaret C. Suazo, Alanah C. Claybaugh, Deborah J. Jones

Journal of Applied Research on Children: Informing Policy for Children at Risk

Socioemotional learning (SEL) is linked to a broad range of child outcomes, with income playing an important role in child SEL, yet most work has compared high- and low-income children yielding less understanding of variability in risk and protective factors within low-income families and communities. Building upon theories in the positive youth development literature and public health frameworks exploring social determinants of health, this study explored the role of family problem-solving, neighborhood social cohesion, and neighborhood resources in understanding child SEL within 1097 low-income families of 3- to 5-year-old children who participated in the National Survey of Children’s Health. Using …

Temporal Variation In Picophytoplankton Pigment Phenotypes Of Two Urban Rivers, Kylee M. Lamberson, Camille E. Wendlandt, Kristin E. Forgrave, Anne W. Thompson

International Journal of Undergraduate Research and Creative Activities

Picophytoplankton are a group of photosynthetic, unicellular organisms, making them key primary producers in aquatic ecosystems. These cells numerically dominate in oceans and lakes where picophytoplankton communities contain phenotypic subpopulations that correspond to biogeographic patterns. In rivers, however, such community dynamics are less studied. We examined the phenotypic subpopulations of picophytoplankton in two converging urban river environments of Portland, Oregon (USA): the Columbia and the Willamette Rivers. From September 2022 through July 2023, we took roughly bi-weekly surface water samples and used multi-laser flow cytometry to distinguish between photosynthetic cells based on their size and pigment fluorescence. We discovered seven …

The Case Against The Five-Paragraph Essay, An Tran

Undercurrents: A Journal of Undergraduate Student Composition

An Tran is a double major in finance and psychology from Boston, MA. An notes that she came from an “underfunded elementary school” where “the curriculum has been rooted in standardized tests, and preparing for them in order to bring in funding.” Given that, she argues that “our value, as students, has become less about the investment of an upcoming generation and more about how much money we could bring in from our test scores.” An notes that the five-paragraph essay “is a core component of this pattern, and it hinders students from truly learning the craft of writing.” She …
