Intercultural Romantic Couples\u27 Interactive Construction of Relational Culture

This study explores intercultural romantic couples and their interactive construction of relational culture. Qualitative methods of inquiry appeared most useful for identifying the processes involved in the social construction of intimates\u27 shared reality and, so, both Conversation Analysis and Joint Interviews were utilized. Five romantic couples whose partners were socilaized within different cultural communities participated in the study. Findings of this study suggest that intercultural romantic couples import cultural resources from their individual cultures into their joint relational culture. These cultural resources included foods, traditions, language, and values. Findings of ths study also suggest that two types of communicative episodes, intimate play and the negotiation of misunderstandings, were particularly important in the couples\u27 construction of a shared relational culture

A multistage linear array assignment problem

The implementation of certain algorithms on parallel processing computing architectures can involve partitioning contiguous elements into a fixed number of groups, each of which is to be handled by a single processor. It is desired to find an assignment of elements to processors that minimizes the sum of the maximum workloads experienced at each stage. This problem can be viewed as a multi-objective network optimization problem. Polynomially-bounded algorithms are developed for the case of two stages, whereas the associated decision problem (for an arbitrary number of stages) is shown to be NP-complete. Heuristic procedures are therefore proposed and analyzed for the general problem. Computational experience with one of the exact problems, incorporating certain pruning rules, is presented with one of the exact problems. Empirical results also demonstrate that one of the heuristic procedures is especially effective in practice

Darkness as a Positive Reinforcer in Weakly Electric Fish

Darkness was used as a positive reinforcer in 14 Gnathonemus petersii fish in an object discrimination task. One subject showed a significant learning response. This study provides preliminary support for the use of darkness as positive reinforcement in weakly electric fish and presents potential areas of interest for future study

Adapting iterative algorithms for solving large sparse linear systems for efficient use on the CDC CYBER 205

Adapting and designing mathematical software to achieve optimum performance on the CYBER 205 is discussed. Comments and observations are made in light of recent work done on modifying the ITPACK software package and on writing new software for vector supercomputers. The goal was to develop very efficient vector algorithms and software for solving large sparse linear systems using iterative methods

Basic linear algebra subprograms for FORTRAN usage

A package of 38 low level subprograms for many of the basic operations of numerical linear algebra is presented. The package is intended to be used with FORTRAN. The operations in the package are dot products, elementary vector operations, Givens transformations, vector copy and swap, vector norms, vector scaling, and the indices of components of largest magnitude. The subprograms and a test driver are available in portable FORTRAN. Versions of the subprograms are also provided in assembly language for the IBM 360/67, the CDC 6600 and CDC 7600, and the Univac 1108

Doming Modes and Dynamics of Model Heme Compounds

Synchrotron far-IR spectroscopy and density-functional calculations are used to characterize the low-frequency dynamics of model heme FeCO compounds. The “doming” vibrational mode in which the iron atom moves out of the porphyrin plane while the periphery of this ring moves in the opposite direction determines the reactivity of oxygen with this type of molecule in biological systems. Calculations of frequencies and absorption intensities and the measured pressure dependence of vibrational modes in the model compounds are used to identify the doming and related normal modes
