The New Economic Liberties, Daniel B. Rodriguez

Northwestern University Law Review

Despite the lack of serious interrogation at the federal constitutional level of economic regulations, there continues to be a fairly robust, energetic attention at the level of state constitutional law to so-called economic liberties. In a number of key cases, including, for example, matters involving occupational licensing, state courts have looked to unique features of their respective state constitutions to assess whether and to what extent regulations undertaken under the police power go too far. The rationales for evaluating and, in some cases, invalidating regulations under economic liberties principles are creative, and also controversial. The development of new interpretive approaches …

From Visual Forms To Character Values: A Conceptual Model Of Visual Meaning-Making For Character Education, Muhammad Gufran, Irsan Kadir, Lukman Ismail, Meisar Ashari

Bahasa dan Seni: Jurnal Bahasa, Sastra, Seni, dan Pengajarannya

Illustrated children's storybooks play a significant role in character education by communicating moral messages through visual narratives. Although previous studies have examined visual literacy, multimodal storytelling, and character education, limited attention has been devoted to explaining how visual forms construct visual meanings that support moral interpretation and represent character values within an integrated framework. Addressing this gap, this study investigates how visual forms in the Indonesian children's storybook Aku Bisa Lebih Baik construct visual meanings, inform moral interpretation, and represent character values. A qualitative visual content analysis was conducted on seven purposively selected illustrations using Wong's (1993) Visual Form Theory …

Metaphors And Socio-Cultural Values In China's Press Statement Translation, Adinda Natassa Valentine Hutabarat

Paradigma: Jurnal Kajian Budaya

In real practice, political text translations are in line with a country’s main foreign policies. Thus, an in-depth understanding on communicative strategies employed in translating political texts, e.g. press statements, is essential. The paper analyses the translation of press statements from the Source Text (Mandarin Chinese) into the Target Texts (English and Indonesian). To elaborate, this study uses van Dijk’s Political Discourse Analysis at the macro (contexts) and micro (texts) levels. By considering Newmark’s equivalent translation concept, as well as metaphor and annotated translations, the analysis reveals that the translation from China’s perspective uses metaphors and China’s socio-cultural values within …

Using a qualitative descriptive case study approach, the research analyzes nine translated songs through the theoretical frameworks of Peter Newmark and Vinay and Darbelnet, while also incorporating contemporary perspectives from digital translation studies, machine translation, and ideological translation. The findings indicate that Musixmatch predominantly applies literal translation strategies in transferring religious terminology, symbolic expressions, and intertextual references. Although this approach enables rapid semantic transfer and general comprehension, it frequently results in the reduction of aesthetic, liturgical, symbolic, and …

Court Reform And State Constitutions, Bryna Godar, Miriam Seifter

Northwestern University Law Review

State legislatures regularly propose and enact laws that seek to shape the substantive outcomes of state courts. These maneuvers, including court-packing, jurisdiction-stripping, and more creative changes to judicial selection or authority, would amount to legal earthquakes at the federal level. At the state level, these efforts often receive virtually no attention.

This Essay brings the potent category of outcome-shaping state court reform measures into focus and evaluates it as a question of state constitutional law. We argue that state constitutions, organized around principles of popular sovereignty, do not bar measures that align state courts with popular preferences or the public’s …

State Constitutionalism's Fragile Wall, Adam B. Sopko

Northwestern University Law Review

The adequate and independent state grounds (AISG) doctrine has long demarcated the perimeter of the U.S. Supreme Court’s authority to review state court decisions, limiting review to questions of federal law. AISG maintains the Court’s primacy over federal law and state courts’ supremacy over state law. A comprehensive review of all filings on the Court’s docket from state courts over the last twenty years reveals that recent applications of AISG consist of subtle but significant departures from existing norms that, together, suggest a reformulation of the Court’s power over state courts that threatens their sovereign law development role. This Essay …

State Greenhouse Gas Emissions Disclosure Laws And The Dormant Commerce Clause: Leveraging The State Interest In Protecting Residents From Deception To Pass The Pike Balancing Test, Matthew Macphail

Northwestern University Law Review

Misleading corporate claims about greenhouse gas emissions pose a high risk of consumer deception, as there is currently no uniform federal standard governing how companies must measure or disclose those emissions. Without a national regulatory scheme, firms can selectively report, use inconsistent methodologies, or market vague “carbon neutral” claims, making it difficult for consumers to assess accuracy or compare companies’ representations.

In 2023, California introduced legislation requiring companies doing business in the state to disclose their greenhouse gas emissions in an effort to bring transparency to this area. But such state-level mandates face a constitutional obstacle: the Dormant Commerce Clause, …

Kikuchi-Fujimoto Disease In Pregnancy: A Rare Case With Atypical Presentation And Potential Viral Trigger, Nicole Nudelman, Ann K. Valencia, Alex Fernandez, Gustavo A. Hernandez, Jeffrey Valencia Uribe, Brian G. Nudelman

Student Publications

Kikuchi-Fujimoto disease (KFD), or histiocytic necrotizing lymphadenitis, is a rare, self-limiting condition characterized by cervical lymphadenopathy, fever, and night sweats. Although KFD is most commonly reported in young Asian women, cases have emerged globally, including among non-Asian populations. The etiology remains unclear, with viral and autoimmune triggers, such as Epstein-Barr Virus (EBV) and systemic lupus erythematosus (SLE), being commonly proposed. Diagnosing KFD is challenging due to its overlapping symptoms with more severe conditions like tuberculosis, malignancies, and autoimmune disorders. Diagnosis typically requires an excisional lymph node biopsy due to the insufficiency of noninvasive methods.

This case report describes a 29-year-old …

Navigating The Edge Of Sentience Without A Scientific Meta-Consensus, Daniel West

Animal Sentience

In The Edge of Sentience (2024, 2025), Birch develops a precautionary framework for crafting public policies about potentially sentient systems. Underlying this framework is a commitment to the democratic principle that the public should authorize all significant moral judgments that arise during the policymaking process. In this commentary, I suggest that Birch’s framework fails to live up to this commitment by requiring scientists without public accountability to make consequential moral judgments. I suggest a friendly amendment to Birch’s framework by replacing the idea of a scientific meta-consensus with the method of formal expert elicitation, a well-tested method of gathering expert …
