Sculpting organism shape requires that cells produce forces with proper directionality. Thus, it is critical to understand how cells orient the cytoskeleton to produce forces that deform tissues. During Drosophila gastrulation, actomyosin contraction in ventral cells generates a long, narrow epithelial furrow, termed the ventral furrow, in which actomyosin fibres and tension are directed along ...

l'orient et la perse ont été au centre de l'attention des  voyageurs européens qui parcouraient le monde pour connaître  l'autre monde. à ce propos, l'altérité qui est l'étude de ce qui est autre et l'image que les étrangers proposent pour cet ailleurs et ces peuples, occupent une place remarquable dans la littérature. des récits de voyage, en tant que le fruit du voyageur contiennent des inf...

This study describes interactional structures and practices in client-identified important events in psychotherapy sessions. Twelve of 16 events from seven client-therapist dyads were found to contain disagreement. A turn-by-turn investigation using conversation analysis displayed three different ways that therapists used to handle disagreement. The first was to orient to the client's disagreem...

What is the relative salience of different aspects of word meaning in the developing lexicon? The current study examines the time-course of retrieval of semantic and color knowledge associated with words during toddler word recognition: At what point do toddlers orient toward an image of a yellow cup upon hearing color-matching words such as "banana" (typically yellow) relative to unrelated wor...

Orientation of animals towards or away from light is a simple behavior commonly found in the animal kingdom. A recent study using zebrafish larvae has revealed the underlying neural logic of this primal choice behavior, by differential use of the retinal ON- and OFF-pathways.

This chapter examines the concept of loss and damage and how they are used in a political and moral context. It takes as a starting point the nuclear accident of Fukushima Daiichi and the short, medium and long-term consequences for the human and non-human environment. It also identifies some potential elements for the transformation of the disaster into a catastrophe, and how we can develop di...

Children with autism were compared to developmentally matched children with Down syndrome or typical development in terms of their ability to visually orient to two social stimuli (name called, hands clapping) and two nonsocial stimuli (rattle, musical jack-in-the-box), and in terms of their ability to share attention (following another's gaze or point). It was found that, compared to children ...
