Fast-Track Ode: A Student-Centered, Game-Based Summer Differential Equations Course, Chamila D. Malagoda Gamage

CODEE Journal

This article describes a student-centered and game-based redesign of an Elementary Differential Equations course taught during a six-week summer session. In this compressed setting, students had to move through the standard course content quickly while still developing procedural fluency, conceptual understanding, and confidence with applications. To support these goals, the course used real-time feedback tools, collaborative problem solving, applications connected to students' fields, and mathematical games. The paper describes the course context, major activities, implementation details, and student feedback. Student responses suggest that the activities were well received and helped students stay engaged, participate regularly, prepare for exams, and see …

An End-To-End Optical And Ethernet Networking Architecture For Next-Generation Satellite Constellations, Gianluca Giuffrida, Francesco Falaschi

Small Satellite Conference

• Modern satellites generate ever-increasing data volumes, increasingly challenging traditional RF links. IngeniArs combines very high speed optical links, up to 10 Gbps, with an onboard Ethernet routing fabric
• Optical data is packetized and dynamically routed for onboard storage or processing, or relayed across the constellation from satellite to satellite until it reaches an available ground station
• The result is reduced time-to-ground, increased contact opportunities, and more resilient end-to-end data delivery across the space and ground segments, despite intermittent link availability

Feasibility Of Failure-Resilient Swarm Formation Flying And Multi-Beam Coherent Apertures In 10000+ High-Density Satellite Swarms, Sumio Morioka

Small Satellite Conference

Direct-to-Device (D2D) communication links satellites directly to ground terminals without large antennas, supporting future Cyber-Physical Systems (CPS) and IoT. Our earlier work [1] showed that a formation of 10,000+ ultra-small satellites, as a coherent phased-array aperture, closes the D2D link budget. This study asks whether the formation can be operated within each satellite’s available power.

The project question was as follows: Among staff members in a skilled nursing facility, does an evidence-based educational intervention improve knowledge of Candida auris infection prevention as compared pre- …

When Childcare Becomes A Crime Space In Contemporary Indonesia, Isyana Kurniasari Konoras, Dr. Dra. Vinita Susanti, M.Si

Jurnal Kriminologi Indonesia

Abstract. The increasing incidence of violence against children in daycare institutions reflects a structural crisis in contemporary child protection systems. This study examines the violence case at Little Aresha Daycare in Yogyakarta to identify the criminogenic factors underlying abuse in institutional childcare settings. The research applies a normative-empirical qualitative method through media-based case studies, legal analysis, and criminological interpretation. The findings demonstrate that violence emerged from the convergence of three major factors: structural strain experienced by caregivers, weak capable guardianship within daycare institutions, and the normalization of abusive disciplinary practices. Robert K. Merton’s Strain Theory explains how economic and occupational …

Beyond Extremism: Rethinking Anarchism In Contemporary Indonesian Security Discourse Through Anarchist Criminology, I Gusti Ngurah Aditia Tjandra Asmara

Jurnal Kriminologi Indonesia

This article examines how contemporary Indonesian security discourse increasingly frames anarchism through the categories of radicalism, extremism, and national security threats. Responding to the emergence of academic and security-oriented narratives that position anarchism as a form of anti-state extremism, this article asks how anarchism is represented and securitized within contemporary Indonesian criminological and security discourse. Using a qualitative critical-discourse analysis approach, this article draws upon perspectives from Anarchist Criminology and Cultural Criminology to examine the construction of anarchism within contemporary Indonesian security narratives. The findings demonstrate that anarchism is frequently reduced into a simplified and homogeneous category of extremism through …

Methamphetamine Trafficking In Indonesia: A Routine Activity And Situational Crime Prevention Perspectives, M Fadli Makarim

Jurnal Kriminologi Indonesia

Abstract. Methamphetamine trafficking represents one of the most significant forms of transnational organised crime affecting Indonesia and appears to be facilitated by Indonesia’s strategic position within global maritime trade networks. Existing explanations have emphasised law enforcement capacity and policy responses, while less attention has been given to the opportunity structures that may facilitate trafficking activities. This study examines how Routine Activity Theory may contribute to explaining methamphetamine trafficking in Indonesia and considers its implications for Situational Crime Prevention. This study employed a structured literature review based on a systematic semantic search of publications indexed in Semantic Scholar and OpenAlex. The …

Symbolic Reform And Police Legitimacy In Indonesia, Nur Zena Anggita Raissa

Jurnal Kriminologi Indonesia

The Indonesian National Police (Polri) are facing a sustained crisis of legitimacy amid increasing public distrust, digital activism, and intensified external oversight. While reform has been repeatedly promised since the post-authoritarian transition, institutional change remains fragmented and largely symbolic. This article examines Polri’s reform trajectory through a criminological lens, drawing on theories of social solidarity (Durkheim), procedural justice (Tyler), and the sociology of professions (Abbott) to analyze the interaction between external pressures and internal organizational dysfunctions. Using theory-driven qualitative analysis of corruption cases, recruitment controversies, and public trust surveys, the study argues that Polri’s legitimacy crisis is rooted not only …

For this basic qualitative design, semistructured interviews with nine students and four staff …

Nasa’S Ecostress Satellite Reveals Widespread Midday Depression In Ecosystem Evapotranspiration, Jingyi Bu, Jingfeng Xiao, Joshua B. Fisher, Yiqi Luo

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Plants often exhibit a midday depression in water use (i.e., transpiration), reflecting a constraint on their ability to sustain maximum water transport, which may occur at the cost of reduced photosynthesis. Eddy covariance observations and geostationary satellites cannot quantify this widespread phenomenon globally while resolving fine-scale spatial variability. Using evapotranspiration measurements from the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) and machine learning, we quantify the global distribution of midday depression in evapotranspiration. Midday depression primarily occurs during peak-growing seasons in temperate zones and dry periods in the tropics, with a morning shift of the peak evapotranspiration time …
