1 Davis, Alan L.A characterization of parallel systemsa taxonomy for parallel processing systems is presented which has some advantages over previous taxonomies. The taxonomy characterizes parallel processing systems using four parameters: topology, communication, granularity, and operation. These parameters and used repetitively in a hierarchical fash...Parallel systems1980
2 Barsky, Brian A.A description of several tools for the synchronization of concurrent processesConcurrent processes are tasks which may be executed simultaneously. When several such processes have access to shared variables, it is necessary to establish some regimen to control this access. Several language tools for expressing various synchronization disciplines are presented.Concurrent processes1980
3 Subrahmanyam, P.A.A new approach to specifying and handling exceptionsAn operation generally exhibits different patterns of behavior over different parts of its domain. Depending upon the context, such behavior may either be conceived of as "normal" or as an "exception." Thus, the behavior of an operation Is quite naturally characterized by the set of partial operatio...Computer operations; Exceptions; Exception handling1980

6 Goldberg, Robert A.Beneath the hood and robe: a socioeconomic analysis of Ku Klux Klan membership in Denver, Colorado, 1921-1925The Invisible Empire of the Knights of the Ku Klux Klan was in numbers and political influence the most powerful social movement of the 1920s and probably the most significant crusade of the American right-wing. Unlike its predecessor of the Reconstruction period or its descendant of today, this Kla...1980
7 Smith, Ken R.Biased estimation in policy research: an illustrative example of ridge regression in a health system modelThe paper develops an argument for the necessity of examining individual coefficients in policy models. As a result of this need, it is posited that something other than OLS estimators should be used since they are inflated and have extremely large variances when multicollinearity is present. Furthe...Policy models; Health systems; Ridge regression1980
8 Gerpheide, George E.Bit-driven logic: a style of digital logic for VLSI designThis memo describes a new style of low-level digital logic design called Bit-Driven Logic (BDL) which may prove attractive for the design of VLSI chips.

23 Fogel, Alan DaleExpressing affection and love to young childrenFew people would seriously contest the proposition that children need love. The belief that children thrive on love is not universal, but in our western culture it has become the foundation for the work of educators and parents (Kagan, 1978). Yet, for all of our certainty about the principle, the p...Expressing affection1980
24 Flynn, John J.Function and dysfunction of per se rules in vertical market restraintsIn 1963, the Supreme Court held it did not know enough about the "economic and business stuff" out of which nonprice vertical market restraints "emerge" to determine whether they should be measured by a "rule of reason" test or one of "per se illegality.'" Seventeen years later, after one flip2 and ...1980
