Simulation Results Of Spaceborne Ssa Using A Comprehensive Passive Radar Model, Chinmay Gaikwad, Filipe Senra, Thomas Alan Lovell, Hao Peng, Berker Pekoz, Tianyu Yang Jan 2026

Simulation Results Of Spaceborne Ssa Using A Comprehensive Passive Radar Model, Chinmay Gaikwad, Filipe Senra, Thomas Alan Lovell, Hao Peng, Berker Pekoz, Tianyu Yang

Publications

In this paper, a high-fidelity simulation framework is developed to assess the feasibility of tracking space debris using a large low-Earth orbit (LEO) satellite constellation equipped with onboard passive radar sensors. By exploiting illumination from a distributed network of ground-based transmitters, the constellation provides consistent line-of-sight access to debris objects at higher altitudes, enabling angles-only detection and tracking. This approach yields a scalable, automated, and cost-effective architecture for next-generation space surveillance and contributes to more resilient space traffic management. A complete angles-only passive-radar orbit-determination pipeline is introduced and demonstrated. Initial orbital states are generated using a rate-aware constrained admissible-region multiple-hypothesis …

The History Of Teaching Indonesian In The United States And Its Pedagogical Shift In The Late 20th Century, Eko Widianto, G.G. Weix, Michael Cullinane Jan 2026

The History Of Teaching Indonesian In The United States And Its Pedagogical Shift In The Late 20th Century, Eko Widianto, G.G. Weix, Michael Cullinane

Journal of Southeast Asian American Education and Advancement

The history of teaching Indonesian in the United States has received limited scholarly attention, despite the field's existence for over eighty years. This study traces its development and identifies three main phases. The first phase began during World War II, when Indonesian was taught primarily to meet military needs through a structural and drill-based approach. In the 1960s and 1970s, instruction was restructured to support academic research, with teaching materials and classroom practices aimed at developing reading skills and preparing students for fieldwork. From the late twentieth century onward, Indonesian programs increasingly adopted communicative approaches influenced by broader trends in …

The Power Of Choice: Transformative Moments In The Lives Of Biblical Heroes, Hershey H. Friedman, Linda Weiser Friedman Jan 2026

The Power Of Choice: Transformative Moments In The Lives Of Biblical Heroes, Hershey H. Friedman, Linda Weiser Friedman

The Journal of Values-Based Leadership

This paper examines pivotal moments in the lives of key biblical figures and explores how these choices shaped both personal destinies and spiritual legacies. Biblical narratives depicting the lives of Adam, Noah, Joseph, Judah, Moses, Ruth, Boaz, David, Solomon, Zerubbabel, Esther, Mordechai, and Samson illustrate that these transcendent moments involve significant moral choices. We see that even revered figures can experience moral failings, and that some individuals can achieve greatness through singular acts of moral courage. These momentous decisions – whether acts of bravery, failures of judgment, vengeance versus reconciliation, worldly power versus spiritual calling, or moments of redemption—reveal profound …

Toward A Contemporary Understanding Of Global Leadership: Relevance Of Diverse Voices, International Collaboration, And New Perspectives, Joseph M. Cervantes, Viet A. Ho, Vui T. Nguyen, Tram N. Le, Minh N.P. Vo Jan 2026

Toward A Contemporary Understanding Of Global Leadership: Relevance Of Diverse Voices, International Collaboration, And New Perspectives, Joseph M. Cervantes, Viet A. Ho, Vui T. Nguyen, Tram N. Le, Minh N.P. Vo

The Journal of Values-Based Leadership

This paper introduces Integral Global Attunement (IGA) as a transformative paradigm in global leadership, emerging in response to the unprecedented shifts catalyzed by theCOVID-19 pandemic. Rooted in the fusion of psychological insight, intercultural consciousness, and ethical stewardship, IGA proposes a fifth wave of leadership—one that transcends transactional strategies to embrace identity, ethics, and relational interconnectedness as central pillars of influence. The writing argues that the current global crises reflect not merely external disruption but an inner dissonance within humanity, calling for a deeper, multi-aware model of leadership. Through the triadic lens of identity (e.g., multicultural integration, visionary consciousness), ethics (e.g., …

The Receptive And Resilient Leader: Thriving In An Era Of Ai And Digital Disruption, Hershey H. Friedman, Nakato Hirakubo, Barbara Jo Lewis

The Journal of Values-Based Leadership

In an Age of Chaos, a term often used to describe the digital AI age, with its explosive growth of information and disruptive technology, businesses face unprecedented turbulence. This paper examines the essential leadership qualities required for success in this environment, arguing that traditional leadership, as seen in the decline of Kodak, Sears, and Blockbuster, struggles to adapt to rapid technological and market shifts. We identify several key competencies for leaders in the digital age: fostering agility, championing an ethical culture, pursuing purpose-driven goals, maintaining technological competency, and genuinely understanding diversity. Perhaps most crucial is receptive leadership, which embodies humility, …

The Effect Of Servant Leadership And Psychological Safety On Employee Commitment And Workplace Engagement, Pierce J. Ippolito, Joshua S. Kay, Kevin J. Hurt Jan 2026

The Effect Of Servant Leadership And Psychological Safety On Employee Commitment And Workplace Engagement, Pierce J. Ippolito, Joshua S. Kay, Kevin J. Hurt

The Journal of Values-Based Leadership

This paper presents a conceptual model of servant leadership, psychological safety, work engagement, and individual commitment. Psychological safety is positioned as a causal factor that provides answers addressing why servant leaders have positive effects on individual commitment and work engagement. The depicted model operates under the consideration that commitment and engagement serve two distinct roles based on the study conducted by Hirschfeld and Feild (2000). Theory-based propositions are developed linking servant leadership and psychological safety to individual commitment and work engagement. Finally, the authors provide a framework that may be utilized for future research.

Pure Leadership Model: A Framework For Leaders Desiring To Lead With An Upright Heart, Matome Liphy Ramalepe Jan 2026

Pure Leadership Model: A Framework For Leaders Desiring To Lead With An Upright Heart, Matome Liphy Ramalepe

The Journal of Values-Based Leadership

Contemporary organisations face intensifying demands for value-driven decision-making, ethical consistency, and service-oriented leadership. These demands underscore the need for frameworks that integrate character formation with organisational performance. In response to these challenges, the Pure Leadership Model conceptualises leadership as a virtue-centred system in which specific virtues function as the mediating link between leadership styles and core organisational values. The model positions the virtues of meekness, compassion, courage, faithfulness, sincerity, and prudence as central mechanisms through which servant, ethical, and authentic leadership translate into the organisational values of service, accountability, and integrity. Through this virtuous mediation, the model ultimately promotes organisational …

The Core Triplet Theory On Leadership, Sajid Hameed Jan 2026

The Core Triplet Theory On Leadership, Sajid Hameed

The Journal of Values-Based Leadership

There are many theories about what makes a leader effective, but no area of research has been studied more than leadership. Traditional models are comprehensive lists of traits; hence, we seldom find a person who possesses them all. One such model is the Core Triplet Theory on Leadership, which simplifies leadership into three core values: Integrity, Empathy, and Vision. These qualities express themselves at three levels: personal, human, and organizational. This theory is a simple, holistic, and pragmatic model to apply, and its adaptability to modern leadership challenges instills confidence. Integrity nurtures trust and ethical consistency at the individual level; …

Dna Of Leadership To Guide Our Existential Purposes Toward Kindness, Hakan Kapucu Jan 2026

Dna Of Leadership To Guide Our Existential Purposes Toward Kindness, Hakan Kapucu

The Journal of Values-Based Leadership

This article examines the intersection of leadership and humanity’s quest for existential purpose, highlighting the role of human values such as kindness, empathy, respect, and ethics in guiding individuals toward meaning. It examines how existential purposes—shaped by philosophical, spiritual, social, and scientific perspectives—align with values that foster personal fulfillment and collective well-being. The article highlights the potential of leaders to address existential struggles, such as the dread of insignificance or isolation, by creating purpose-driven workplaces. Two leadership styles, servant leadership and technoversal leadership, are presented as exemplary models. Servant leadership prioritizes community, fostering environments where individuals discover purpose through shared …

Living Ethically: An Inner Capacity Struggling To Become A Moral Reality, Joseph P. Hester

The Journal of Values-Based Leadership

Spiritual refinement is a part of our essential moral self. As a seedbed of moral consciousness, spiritual refinement is a perpetual activity, as well as a reservoir of experiences, needed for shaping the world and responding to its ethical demands. Begun as moral insight and utilizing the moral imagination, the actual details and social structures of morality are developed and applied in real life situations where they mature and change as they overlap and are tempered by others.

Mapping The Multifarious Image In Time Of Globalization, Anne-Laure Oberson Jan 2026

Mapping The Multifarious Image In Time Of Globalization, Anne-Laure Oberson

Artl@s Bulletin

Abstract: In this paper, I examine the evolving concept of the image, exploring the philosophical implications of its complex, multifaceted nature. I question the value of terms such as icon, simulacrum, and image in reference to Gilles Deleuze’s text Difference and Repetition. I argue for a pluralistic approach to understanding images as they embody more than a duality of visible-invisible dimensions. I seek to capture the multifariousness of the image to understand its transformative power. In conclusion, the paper suggests reevaluating image discourse to better engage with the evolution of its implications in a global context.

Queens, Pearls And Spirochaetes, Radu Suciu Jan 2026

Queens, Pearls And Spirochaetes, Radu Suciu

Artl@s Bulletin

Abstract: In December 2019, the New Zealand AIDS Foundation (now the Burnett Foundation) released a public health campaign raising awareness about the increasing rates of syphilis infections in New Zealand. The campaign consisted of photographs that contrasted contemporary backgrounds of bars and nightclubs with actors wearing theatrical costumes akin to the Elizabethan period. This reinforced the perceived idea that syphilis was a disease resurging from the distant past. This paper discusses one of the campaign’s most iconic portraits by analysing its shared cultural, artistic, and medical references (explicit or implicit) and their shifting meanings through time.

Roaming Pixels: Clipping The Operative Close-Up, Vanessa Gravenor Jan 2026

Roaming Pixels: Clipping The Operative Close-Up, Vanessa Gravenor

Artl@s Bulletin

Abstract: This essay examines the disseminated war image as it takes off at the speed of light. It seeks to challenge the legacy of the post-structuralist spectator who watches war by complicating this figure with post-colonial perspectives where the distanced, global war dissemination collapses into the intimate, subjective gaze. Focusing on artist–theorist perspectives, it traces strategies for working with the digital broadcast of war, specifically from the 2000s and 2010s, and artists who peer into uncertain pixels and the cruelty of the close-up.

Zusammenfassung: In diesem Essay wird das verbreitete Kriegsbild untersucht, das mit Lichtgeschwindigkeit abhebt. Er versucht, das Erbe …

The Global On Display? Art, Circulation, And The Institutional Framing Of Practices, Florian Rosinski Jan 2026

The Global On Display? Art, Circulation, And The Institutional Framing Of Practices, Florian Rosinski

Artl@s Bulletin

Abstract: This article examines how the notion of “circulation” structures institutional discourse in contemporary art exhibitions focused on digital photography. Drawing on curatorial texts, mediation materials, and interviews from four shows, it uses discourse analysis to show how circulation operates as both a symbolic framework and an organizational logic. While it helps articulate tensions in the global art field, it also neutralizes critique by reaffirming artistic centrality and marginalizing audiences. The study questions whether circulation illuminates or obscures the very power relations it names.

Brute Force Branding: Variations & Repetitions Of The Almighty Dollar Banknote, Rui-Long Monico Jan 2026

Brute Force Branding: Variations & Repetitions Of The Almighty Dollar Banknote, Rui-Long Monico

Artl@s Bulletin

Abstract: This paper examines the U.S. dollar as a global brand and mythic icon, revealing how its stable aesthetic asserts dominance and infiltrates daily life. Through visual analysis and global comparison, it shows how banknotes are battlegrounds where art, identity, and geopolitics collide—currency as a weapon of soft power and cultural hegemony. The dollar’s visual inertia—ritualized, repeated, reappropriated—cements its supremacy as a symbolic force, where repetition enforces authority and variation sparks both resistance and conformity. Banknotes emerge as tools of statecraft and vessels of collective memory, as reflected in the author’s bespoke creation accompanying this study.

Image Circulations And Economic Imagination: Framing The Peruvian And Chilean Peripheries At The End Of The 19th Century, Alexandre Puche Jan 2026

Image Circulations And Economic Imagination: Framing The Peruvian And Chilean Peripheries At The End Of The 19th Century, Alexandre Puche

Artl@s Bulletin

Abstract: This study explores two cases of photographic circulation between Peru, Chile and France in the late nineteenth century to show how images contributed to the requalification of the region within global commercial geography. It also proposes a historical methodology that considers visual repetition as a traceable product of transnational circulation. This approach sheds light on both certain mechanisms behind Atlantic propaganda regarding South America’s economic potential and the structuring role such circulations played in shaping regional representations.

What Makes Art Images Travel So Well? Repetition, Variation, And The Global Life Of Images, Béatrice Joyeux-Prunel Jan 2026

What Makes Art Images Travel So Well? Repetition, Variation, And The Global Life Of Images, Béatrice Joyeux-Prunel

Artl@s Bulletin

What do we actually know about how images become global? This article takes stock of current approaches to studying their worldwide circulation. Drawing on findings from the Visual Contagions project—which maps 15 million illustrations across 18,000 periodicals in more than 50 countries—we now see that in the age of print, only a small fraction of images traveled widely, with art reproductions proving to be the most mobile. The central question, then, is whether this broader circulation of art images is linked to their formal power. When examined from multiple perspectives, the answer cannot be a simple yes. Visual circulation also …

Food Insecurity. A Factor In Criminal Behavior?, Jerrod Brown, Jeremiah Schimp, Leanne Skehan, Janina Cich Jan 2026

Food Insecurity. A Factor In Criminal Behavior?, Jerrod Brown, Jeremiah Schimp, Leanne Skehan, Janina Cich

Nutritional Neurocriminology Today

This article examines how food insecurity and limited access to nutritionally adequate foods impair cognitive function, emotional regulation, decision-making, and impulse control. Emerging research purports that individuals experiencing food insecurity face increased risks of mental and physical health problems, violent behavior, delinquency, heightened childhood vulnerability, and criminal justice involvement across the lifespan. The article advocates for increased awareness, routine screening, and specialized training for professionals in mental health, social services, and the criminal justice system to address food insecurity, thereby supporting long-term policy and community-level strategies that reduce criminal behavior and improve outcomes for vulnerable populations.

Antimicrobial Resistance Of Cultivable Bacteria Isolated From Sorcerer’S Cave In Texas, Jennifer R. Huddleston, David E. Sanderson, Braden J. Smith, Joshua M. Brokaw, Evan M. Babb, Jeffrey T. Wooliscroft

International Journal of Speleology

Studying caves with minimal human contact offers insights into antimicrobial resistance before human influence. In this study, we isolated 315 bacterial strains from Sorcerer’s Cave in Texas and evaluated their resistance to seven common antimicrobials. Under half (41.4%) of the Gram-positive isolates and 68.4% of the Gram-negative isolates were resistant to three or more antimicrobials. The two most common genera identified were Pseudomonas and Bacillus. Compared to bacteria isolated in previous cave studies, Sorcerer’s Cave bacteria exhibited more extensive antimicrobial resistance. This study underscores the importance of minimally disturbed cave environments in advancing our knowledge of antimicrobial resistance present …

Beyond Broadcasting: Irish Radio And The Convergent Mediascape Of The 21st Century, Daithí Mcmahon

Irish Communication Review

As we reflect on one hundred years of broadcast radio in Ireland, we are reminded of the resilience required to remain a prominent fixture in what has become a highly congested digital mediascape. The Irish radio industry’s survival and continued success has been made possible, paradoxically, by remaining true to its origins as a linear, aural medium - while at the same time adapting to become a modern, digitally convergent one. Over the last twenty-five years, Irish radio has continued to serve as a live, spontaneous and trustworthy medium, providing an ever-present voice in Irish people’s lives at home and …

“A Questionable Culture That Has Dominated Rté For Too Long”: Early Funding Structures And The Nature Of Irish Public Service Media, Roddy Flynn Jan 2026

“A Questionable Culture That Has Dominated Rté For Too Long”: Early Funding Structures And The Nature Of Irish Public Service Media, Roddy Flynn

Irish Communication Review

RTÉ is unusually reliant on advertising revenue in comparison with other European public service media. This article suggests that understanding why this is the case requires a look at the longer history of RTE’s finances, back to the era when the broadcasting service was directly run as an element of the Department of Posts and Telegraphs and thus, indirectly, the Irish state. This status notwithstanding, a sequence of government decisions in the 1930s created a situation whereby the public service medium became reliant on advertising income for its survival, a dependency relationship which not only persisted but became even more …
