n the nervous system, guidance molecules called semaphorins bind to receptors called plexins to induce motility and regulate axonal pathfinding. Now, Swiercz et al. (page 869) show that plexin-B1, after binding its ligand semaphorin 4D (Sema4D), forms a heterodimer with the tyrosine kinase ErbB2. This raises the intriguing possibility that the semaphorins and the EGF-like ligands of ErbB recept...

Do Households with Debt Problems Spend Less?

At the end of 2012, almost one-fifth of owner-occupier mortgages were in arrears. A further five per cent not in arrears were classified as “restructured” loans. This Economic Letter looks at the impact of financial distress on household expenditure patterns by comparing the behaviour of households in mortgage distress with similar households in the general population.

Do the Reciprocal Trust Less?

Do the Reciprocal Trust Less? We study the intrapersonal relationship between trust and reciprocity in a laboratory experiment. Reciprocal subjects trust significantly more than selfish ones. This finding raises questions about theories of social preferences which predict that “fairer” players should trust less. JEL Classification: C91, D63

Deconstructing the Deformable Parts Model: Do More with Less

The deformable parts model (DPM) [1] is a successful detection model that continues to achieve state-of-the-art results in object detection. While the model’s success is attributed to the deformable parts, the proposed system has many other design choices such as the use of multi-resolution HOG features, the sampling of parts from high energy areas, the use of a mixture model, etc. Recently, th...
