Strong deflection gravitational lensing

, 2012
In this work are reviewed several aspects of gravitational lensing produced by astrophysical bodies that strongly curve the spacetime in their vicinity. When an object with a photon sphere (e.g. a black hole) is interposed between a source and an observer, in addition to primary and secondary images due to small deflections of the light rays, there are

Agglomeration Behavior of Nonmetallic Particles on the Surface of Si‐Killed Liquid Steel Using HT‐CSLM: An In Situ Investigation

steel research international, EarlyView.
The in situ agglomeration behavior of semisolid Al–silicate inclusions in Si‐killed steel is studied using high‐temperature confocal scanning laser microscopy. Particle motion and interparticle forces at the steel/argon interface are quantified and compared with a modified capillary interaction model.

Strong Gravitational-wave Lensing Posterior Odds

The Astrophysical Journal
Abstract Like light, gravitational waves are gravitationally lensed by intervening massive astrophysical objects—such as galaxies, clusters, black holes, and stars—resulting in a variety of potentially observable gravitational-wave lensing signatures.

Unveiling the “Gray Zone”: Characterizing Young People's Moderate STEM Identities

Journal of Research in Science Teaching, EarlyView.
ABSTRACT Understanding how students identify with STEM (Science, Technology, Engineering, Mathematics) is crucial for fostering broader and more equitable participation within these fields. While existing research has focused on students who either strongly identify with STEM or disengage from it, this study explores the moderate STEM identities of ...

Late‐Arriving Multilingual Learners' Transition from K–16 Education to the Workforce: Cultural Capital and Habitus Adaptation across Fields

TESOL Quarterly, EarlyView.
Abstract English learners (ELs) in US K–12 schools face systemic barriers that constrain their college and career readiness. Although research has richly documented ELs' limited opportunities to learn in high school and barriers to postsecondary education, much less is known about how late‐arriving ELs move from high school to community college (CC ...

What Remains Ours to Think? Reclaiming Critical Thinking in AI‐Augmented Student Leadership Education

New Directions for Student Leadership, EarlyView.
ABSTRACT The arrival of generative artificial intelligence in learning environments has created an urgent question for leadership educators: what remains distinctly ours to think in the act of learning to lead? This article proposes a third orientation beyond the familiar poles of embrace and resistance, centering the reciprocal holding environment as ...

Changing practices, not just rules: Rethinking the institutionalisation of deliberative engagement

Australian Journal of Public Administration, EarlyView.
Abstract When Victoria introduced legislation requiring all 79 councils to adopt deliberative engagement, 92% continued practices the legislation had just removed. This paradox reveals a fundamental challenge in embedding democratic innovations within existing systems of government: legislation signals commitment but cannot disrupt entrenched ...

When Thriving for More Collapses the System: The Academic Reproduction of Uncaring Structures

British Journal of Management, EarlyView.
Abstract This essay argues that the widening gap between aspirational aims and visionary orientations and the prevailing practices in neoliberal academia stems from deeper, historically rooted, market‐based logics shaping our institutions, increasingly governed by economic values and academic subjectivities therein.

Who Is a Patriotic Man? Rethinking Hegemonic Masculinity in Modern Iran

Gender &History, EarlyView.
ABSTRACT This article examines the analytical viability of the concept of “hegemonic masculinity” in the historical study of masculinities in early‐twentieth‐century Iran (c.1890–1941). It argues that a radical problematizing of the concepts of hegemony, class, “the West,” and patriotism helps us move beyond the binaries of Western‐Iranian and modern ...

A War of Words: Framing the Austrian Civil War through the Language of the Combatants

History, EarlyView.
Abstract The Austrian civil war was a four‐day conflict in 1934 between the largest left‐wing paramilitary, the Schutzbund, and government forces aligned with the largest right‐wing paramilitary group, the Heimwehr. The Schutzbund was quickly and brutally suppressed through the use of overwhelming force, armoured vehicles and even artillery deployment ...
