A Pedagogical Analysis Of How Unprefixed Verbs Of Motion Are Presented In Instructional Materials For Beginner Russian Language Learners, Elena Petrova, Kris Lewis

Russian Language Journal

It is well-known that verbs of motion (VoM) are quite challenging for Russian language learners. We analyze four VoM-specific pedagogical materials (three textbooks and one mobile application) for their usefulness in supporting second language acquisition and the development of new thinking-for-speaking (TFS) patterns in beginner-level Russian language learners. Focusing on directionality, scaffolding, comprehensible input, the use of visuals, and communicative activities, we highlight how these materials lay a foundation for understanding VoM but are not sufficient for helping learners fully develop new TFS patterns. We pose recommendations for future research, teaching, learning, and materials development in the area of Russian …

Purdue’S Side Effects: Using Due Process To Realign Mass Tort Bankruptcies, William A. Organek

BYU Law Review

In Harrington v. Purdue Pharma, the United States Supreme Court held that victims of the opioid crisis could not be forced to release their independent claims against the Sacklers, who owned and controlled Purdue, without the victims’ consent. Such releases had become a controversial mainstay of mass tort bankruptcy filings. Yet Purdue was decided on narrow, textualist grounds, leaving as a side effect many seemingly disparate and difficult questions unanswered. This Article argues that Purdue and its open issues should be analyzed through a broader due process lens in tension with some aspects of current bankruptcy practice but consistent with …

Faith On The Frontlines: Exploring The Religiosity Of Ukrainian Soldiers During War, Alexander Karlsson

Occasional Papers on Religion in Eastern Europe

Wartime religiosity among Ukrainian Christian soldiers reveals a spectrum of spiritual responses shaped by personal experience, cultural identity, and institutional dynamics. Interview-based evidence indicates that war influences religious engagement in diverse and often contradictory ways. For many, religiosity intensifies during moments of danger, functioning more as a coping mechanism than a transformation of belief. Institutional realignment may also reflect broader socio-political changes, as soldiers gravitate toward religious communities that resonate with their evolving values. For some, the adoption of Norse mythology illustrates the fluidity and adaptability of religious identity in wartime. Simultaneously, confrontations with theodicy may give rise to both …

Regularity, Uniqueness And The Relative Size Of Small And Large Scales In Sqg Flows, Z. Akridge, Z. Bradshaw

Mathematical Sciences Faculty Publications and Presentations

The problems of regularity and uniqueness are open for the supercritically dissipative surface quasi-geostrophic equations in certain classes. In this note we examine the extent to which small or large scales are necessarily active both for the temperature in a hypothetical blow-up scenario and for the error in hypothetical non-uniqueness scenarios, the latter understood within the class of Marchand's solutions. This extends prior work for the 3D Navier-Stokes equations. The extension is complicated by the fact that mild solution techniques are unavailable for supercritical SQG. This forces us to develop a new approach using energy methods and Littlewood-Paley theory.

Friction Points Between The Eu Data Act And Wto Law, Pedro R. Borges De Carvalho

Indian Journal of International Economic Law

It has been noted that many of the provisions of the EU Data Act are protectionist in character, seemingly designed to guard data as a national resource to be explored by EU actors first and foremost, and not to be exported, to the detriment of third-country companies. To international trade treaty partners, most notably the United States, it may seem as though the EU’s policy of digital sovereignty, in its current contours, risks violating WTO Law, which is premised on ideals of global free trade and comparative advantage. This essay analyses the most problematic provision of the Data Act in …
