A frame is any payo¤ relevant preference parameter broadly de...ned to include psychological considerations such as reference points, beliefs, aspirations etc. An endogenous frame is a preference parameter that is, in turn, a¤ected by chosen actions. We model decions in two ways. A standard decision problem is one where the chosen action is required to be optimal when the feedback e¤ect from ac...

There has been a considerable amount of work on retrieving functions in function libraries using their type as search key. The availability of rich component specifications, in the form of behavioral types, enables similar queries where one can search a component library using the behavioral type of a component as the search key. Just like for function libraries, however, component libraries wi...

This paper provides experimental evidence on the relationship between education and early fertility in a developing country. We exploit experimental variation in the cost of education for a cohort of 18,000 students in Western Kenya. Students in Kenyan primary schools wear uniforms which typically cost about $6. In 163 schools randomly selected from among 328, students enrolled in grade 6 at ba...

Every acupoint has specific indications for acupuncture treatment. These indications, primarily established based on the meridian system, have spatial patterns of symptoms on the human body. We investigated the associations between acupoints and symptom locations in 75 patients with chronic pain who were asked to sketch the localization of their symptoms on body schemes using the bodily sensati...

In this paper, we study pattern matching conditions in the cycle structures of permutations. We develop methods to find the joint distribution of the number of cycles and the number of cycle descents over the set of permutations in the symmetric group Sn which have no cycle occurrences or no consecutive cycle occurrences of a given pattern or set of patterns. Our methods also allow us to refine...

Route directions describe the sequence of actions a moving person needs to take to reach a goal in an environment. When generating directions, speakers not only specify what to do. They also refer to landmarks located along the route. We report two studies intended to identify the cognitive functions of landmarks. In the first study, participants learned a route in an urban environment. They th...

The modulus and phase of the reduced logarithmic derivative of the Hankel function zH^'iz)/Hi'\z) for complex variable z and real order v, are investigated. Special attention is paid to the location of saddle points and their trajectories as v varies.

Stimulation at specific acupoints can activate cortical regions in human subjects. Previous studies have mainly focused on a single brain region. However, the brain is a network and many brain regions participate in the same task. The study of a single brain region alone cannot clearly explain any brain-related issues. Therefore, for the present study, magnetic stimulation was used to stimulate...

Last lecture we introduced the cutting method, and we sketched the proof of Theorem 2. We can pose variations on Question 1 by replacing lines with other curves in the plane. What happens for circles? Unit circles? Parabolas? Ellipses? These are four major open problems of incidence geometry! Let us try to explain why these problems are hard, or at least why they cannot be solved by the same me...
