Three closely linked X‐chromosomal genes potentially control sex determination in Cannabis sativa

open access: yesNew Phytologist, EarlyView.
Summary Sex determination mechanisms in dioecious plants remain poorly understood yet offer an excellent model system to study genetic changes underlying morphological evolution. We investigated the genetic basis of sex determination in Cannabis sativa, combining quantitative trait locus mapping in a segregating population, comparative transcriptomics ...

Locally adapted Arabidopsis thaliana accessions show transcriptomic plasticity in a multi‐timescale analysis of whole‐genome gene expression in a natural environment

open access: yesPlant Biology, EarlyView.
Natural Arabidopsis thaliana accessions showed remarkable plasticity in both life‐cycle phenology and whole‐genome gene expression patterns in in natura field experiments. Nevertheless, local adaptation in fitness‐related life‐history traits can also be detected at the whole‐genome gene expression level.

A Natural Language Processing Approach to Identifying Partisan Framing of Climate Change Denialism, Fatalism, and Solutions in US Congressional Speeches

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT This study examines the evolution of climate change discourse in the United States Congress from 1987 to 2017, employing natural language processing (NLP) techniques to analyze floor speeches. Using a la carte (ALC) word embeddings, we investigate how Democratic and Republican members of Congress frame climate change, focusing on denialist ...

Evolution of generic competitive strategies and the importance of Michael E. Porter La evolución de las estrategias genéricas de competición y la influencia de Michael E. Porter A evolução das estratégias genéricas de competição e a influência de Michael E. Porter

open access: yesREGE Revista de Gestão, 2010
Generic competitive strategies are considered almost as archetypes in Business Administration, sometimes leading to over simplification of their concepts as well as underestimation of their importance. Since publication in 1980, as part of Michael E. Porter's book Competitive Strategy, the generic strategies of Differentiation, Leadership in Total Cost

Coalition Breakdown and Subsystem Exit

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT Why actors choose to work together (or not) to advance policy has been the central area of inquiry within the Advocacy Coalition Framework (ACF). Existing research has mainly emphasized the pathway towards coalition formation and evolution, underscoring the stable patterns of allies and opponents observable in policy processes over a decade or
