Geopolitical imaginations and construction of ‘the people’: Turkey’s populist spatial logic in its engagement with Africa

Hamid Talebian, Mira Demirdirek

Abstract Research on foreign policy at the intersection of International Relations, critical geopolitics and the study of populism remains limited, particularly regarding emerging powers. While political geographers have shown that foreign policy is shaped by geopolitical imaginations, little attention has been paid to how populist logics inform the spatial articulation of such imaginaries. The article addresses this gap by introducing ‘Populist Spatial Logic’ (PSL) as a conceptual lens for analysing how space and …

Query-based multimodal interaction and adaptive gated fusion for Alzheimer's disease detection

Yongqi Shao, Cong Tan, Hong Huo, Tao Fang

Early detection of Alzheimer's disease is crucial for delaying disease progression and improving patient outcomes. Speech has emerged as a promising biomarker for Alzheimer's disease detection because it is convenient, non-invasive, and low-cost. However, existing studies often rely on a single modality or fail to fully exploit complementary information across modalities. To address these limitations, we propose a query-based multimodal interaction and adaptive gated fusion framework for Alzheimer's disease detecti …

Selective Similarity Preference: People with a “Darker Core” Desire More Partner Similarity in Dark Traits but Not in Big Five

Hao Wu, Shanhong Luo, Whitney Wall, Karryll Winborne-Phillips

Research on assortative mating has shown that couples share strong similarities in demographic and attitudinal variables, while the similarity in personality is generally weak. However, a recent meta-analysis indicated that couple similarity in dark traits is considerably greater than that in the Big Five. If these differential similarities are primarily due to active preference, we expect that (1) the desire for similarity in dark traits should be higher than that for the Big Five and (2) the strongest desire for …
