-level functional partitioning. These partitions are mapped into information process-ing modules. The modules are assigned to nodes of the distributed information systems. A central role is assigned to modules that mediate between the users ' workstations and data re-sources. Mediators contain

, is evidence of the above. However, the map-reduce paradigm is too low-level and rigid, and leads to a great deal of custom user code that is hard to maintain, and reuse. We describe a new language called Pig Latin that we have designed to fit in a sweet spot between the declarative style of SQL, and the low

-based primitives and incremental rendering. The method also can be used to greatly accelerate the computation of motion blur and soft shadows cast by area light sources.

, they have great difficulty because these harsh conditions are different from thost of the local objects they are used to dealing with. Third, IDL hides information about the tradeoffs any implementation of an object must make. Fourth, there is presently no way to systematically reuse current technology

in an inconsistent and often incorrect fashion. The problem we study here is the task of merging data from multiple sources in as efficient manner as possible, while maximizing the accuracy of the result. We call this the merge/purge problem. In this paper we detail the sorted neighborhood method that is used

conceptual refocusing and broadening to account for the location decisions of people as opposed to those of firms as sources of regional and national economic growth. In doing so, this article hopes to spur wider commentary and debate on the critical functions of cities and regions in 21st-century creative

Affordable housing has remained one of the biggest problems in the Sacramento region over the past four years. Today, almost half of the area residents (47%) aren’t able to find a home that they can afford and would buy in the four-county Sacramento region if they decide to purchase a new house in the near future. This includes 43 percent of current homeowners and half of the middle-class families who are making $30,000 to $99,999 a year. This American dream is even more illusive for households making less than $30,000 (67%), non-homeowners (57%), unmarried (57%), and elderly residents (58%). In fact, this high cost has made one-third (33%) of the public think about moving away, which is eight percentage points higher than the state as a whole (25%). This is particularly the case for non-homeowners (48%), people 40 or younger (43%), respondents with income less than $30,000 (41%), and those who are nonwhite (37%). Of those who are pondering relocation, about two-thirds (65%) plan to leave California.

with very different query capabilities. Garlic's optimizer extends the rule-based approach of [Loh88 ] to work in a heterogeneous environment, by defining generic rules for the middleware and using wrapper-provided rules to encapsulate the capabilities of each data source. This approach offers great
