Inflexibility in motion

Inflexibility in motion

ell migration depends on polarized actin polymerization at a cell's front edge. To get the most out of these actin networks, plasma membrane flexibility must be similarly polarized, according to results from Amit Vasanji, Paul Fox (Cleveland Clinic Foundation, Cleveland, OH), and colleagues. The group shows that the membrane is stiffest at the front of migrating endothelial cells. This oriented...

Inflexibility and Stock Returns

Investment-based asset pricing research highlights the role of irreversibility as a determinant of firms’ risk and expected return. In a neoclassical model of a firm with costly scale adjustment options, we show that the effect of scale flexibility (i.e., contraction and expansion options) is to determine the relation between risk and operating leverage: risk increases with operating leverage f...

Rigidity and Inflexibility in Conformal Dynamics

Psychological Inflexibility and Child Anxiety

Psychological flexibility is the main outcome of acceptance commitment therapy. Insight into the usefulness of measuring psychological flexibility is an important step to enable studies on the effectiveness of acceptance commitment therapy in middle-aged children (8-10 years). For this purpose, we examined the factor structure, the construct validity and the reliability of the Avoidance and Fus...

The prod of on-site course inflexibility

The aim of this research was to study the effect of flexibility on e-learning use within the framework of the technology acceptance model (TAM). Concern with flexibility arises from university programmes increasingly blending distance education and on-site learning, made possible by internet-age computer technologies. The use of these technologies is bound to their enabling to break away from t...
