Article Abstract

Linguistics needs to embrace all the way down a key feature of language: its diversity. In this paper, we build on recent experimental findings and theoretical discussions about the neuroscience and the cognitive science of linguistic variation, but also on proposals by theoretical biology, to advance some future directions for a more solid neurocognitive approach to language diversity. We argue that the cognitive foundations and the neuroscience of human language will be better understood if we pursue a unitary explanation of four key dimensions of linguistic variation: the different functions performed by language, the diversity of sociolinguistic phenomena, the typological differences between human languages, and the diverse developmental paths to language. Succeeding in the cognitive and neurobiological examination and explanation of these four dimensions will not only result in a more comprehensive understanding of how our brain processes language, but also of how language evolved and the core properties of human language(s).

Camouflaged Object Segmentation (COS) faces significant challenges due to the scarcity of annotated data, where meticulous pixel-level annotation is both labor-intensive and costly, primarily due to the intricate object-background boundaries. Addressing the core question, "Can COS be effectively achieved in a zero-shot manner without manual annotations for any camouflaged object?", we propose an affirmative solution. We analyze the learned attention patterns for camouflaged objects and introduce a robust zero-shot COS framework.

Background: Community engagement is key to developing culturally responsive public health interventions that resonate with diverse populations and promote health equity.

Brief Description Of Activity: We applied an adapted version of Boot Camp Translation (BCT), a community-based participatory approach, to develop culturally and locally relevant messaging and materials for diverse populations. This adapted BCT approach focuses on three core themes: (1) Listen, (2) Empower, and (3) Co-Create, or LEC.

Overcoming gaps and barriers to effectively integrate social science in European conservation.

Conserv Biol

September 2025

Alfred Toepfer Academy for Nature Conservation, Schneverdingen, Germany.

The importance of social science to address the human dimensions of natural resource management is increasingly recognized in the conservation field, yet the application of associated concepts, theories, methods, and data remains underrepresented in parts of Europe. Common barriers and gaps, persistent over decades, including institutional constraints, work environment, different cultures and languages between natural and social science disciplines, lack of qualified personnel, and an accessible professional community, are often cited as underlying and driving factors. To better understand, contextualize, and inform solutions for wider use of social science, we analyzed interactions with conservation researchers and practitioners across a series of organized events from 2018 to 2023 (e.

COVID-19 and the moral failure to protect the most vulnerable.

The USA's COVID-19 pandemic experience is an example of privileged thinking that what generally works for those in power ought to be the standard for what makes medical interventions, research, treatments, and policy ethical. As a result of not focusing on doing whatever was required for vulnerable or susceptible populations or their members to achieve their health and flourishing, there are a disproportionate numbers of COVID-19 infections and deaths in Black, Hispanic, and indigenous communities. Future studies will likely show even more harm and larger health failure than known of now.
