IN April 1961 it became apparent that an increasing number of patients was attending the out-patients department of the Birmingham and Midland Eye Hospital with a follicular conjunctivitis, and an associated pre-auricular adenitis, which often proceeded to a keratitis. This was soon recognized as an outbreak of epidemic keratoconjunctivitis and therefore precautionary measures were immediately ...

We prove the Strengthened Hanna Neumann Conjecture. We give a more direct cohomological interpretation of the conjecture in terms of “typical” covering maps, and use graph Galois theory to “symmetrize” the conjecture. The conjecture is then related to certain kernel of a morphism of sheaves, and is implied provided these kernels are co-acyclic in the covering cohomology theory. This allows us t...

The understanding and interpretation of unconscious symbolism is one of the main tools of the psychologist. Often he is faced with the task of understanding and recognizing the meaning not only of a particular symbol but also of the whole process of symbol formation. This applies particularly to work with patients who show a disturbance or inhibition in the formation or free use of symbols, as ...

From puberty onward, mating becomes a major focus of thought: Whom shall I date? Shall I stay with my current partner, or look for someone else? Can I find someone better? Will she like me? Will he leave me for someone else? How popular with the opposite sex am I, compared to my peers? These types of questions, which sometimes persist throughout adulthood, point to the complexity of mating deci...
