Highly Accomplished Teachers (HATs) think deeply about skilled pedagogy in ways that illuminate its complexity and the challenges of pedagogical change. The sophistication, breadth, depth their thinking often goes well beyond way teachers responses to professional development (PD) are typically positioned extensive, quite pessimistic literature on teacher PD. This study extends our previous res...

Bug-bounty programs have the potential to harvest the efforts and diverse knowledge of thousands of white hat hackers. As a consequence, they are becoming increasingly popular as a key part of the security culture of organizations. However, bug-bounty programs can be riddled with myriads of invalid vulnerability-report submissions, which are partially the result of misaligned incentives between...

Many classical puzzles involve hats. The general setting for these puzzles is a game in which several players are each given a hat to wear. Associated with each hat is either a color or a number. Every player can see the color or number of everyone else’s hat but not his own. The players are then trying to figure out the colors or the numbers on their own hats. The Three-Hat Problem is one of s...

We analyze the following general version of deterministic Hats game. Several sages wearing colored hats occupy vertices a graph. Each sage can have hat one k colors. tries to guess color his own merely on basis observing neighbors without exchanging any information. A predetermined guessing strategy is winning if it guarantees at least correct individual for every assignment present an example ...

2. The Council of Wizards is tested in the followingway: The King lines the wizards up in a row and places on the head of each of them either a white hat or a blue hat or a red hat. Each wizard sees the colours of hats of the people standing in front of him, but he neither sees the colour of his hat nor the colours of hats of the people standing behind. Every minute some of the wizards must ann...

While the CAP Theorem is often interpreted to preclude the availability of transactions in a partition-prone environment, we show that highly available systems can provide useful transactional semantics, often matching those of today’s ACID databases. We propose Highly Available Transactions (HATs) that are available in the presence of partitions. HATs support many desirable ACID guarantees for...

The heteromeric amino acid transporters (HATs) are composed of two polypeptides: a heavy subunit (HSHAT) and a light subunit (LSHAT) linked by a disulfide bridge. HSHATs are N-glycosylated type II membrane glycoproteins, whereas LSHATs are nonglycosylated polytopic membrane proteins. The HSHATs have been known since 1992, and the LSHATs have been described in the last three years. HATs represen...

We present an overview of our work in information fusion for intelligence analysis. This work includes the Hats Simulator and the COLAB system. The Hats Simulator is a parameterized model of a virtual world in which hundreds of thousands of agents engage in individual and collective activities. Playing against the simulator, the goal of the analyst is to identify and stop harmful agents before ...

We study a game puzzle that has enjoyed recent popularity among mathematicians, computer scientist, coding theorists and even the mass press. In the game, n players are fitted with randomly assigned colored hats. Individual players can see their teammates’ hat colors, but not their own. Based on this information, and without any further communication, each player must attempt to guess his hat c...
