OBJECTIVE: To examine how knowledge about the Texas top 10% law influences college enrollment decisions of high achieving students minority and nonminority students. DATA AND METHODS: Using a representative survey of graduates from Texas public high schools in 2002, we compare self-reported and transcript-verified class rank and estimate probit models to assess the likelihood that top-ranked m...

The goal of this report is to survey state of the art and existing approaches for parallel programming on workstation clusters with special emphasis on object{oriented programming. First, workstation clusters as parallel computing platforms are characterized and fundamental concepts for parallel programming are discussed. Then, an overview of existing tools, systems, languages, and environments...

Message-passing is a well known approach for parallelizing programs. The widely used standard MPI (Message passing interface) also defines C++ bindings. Nevertheless, there is a lack of integration of object-oriented concepts. In this paper, we describe our design of TPO++1, an object-oriented message-passing library written in C++ on top of MPI. Its key features are easy transmission of object...

This paper focuses on message handling in multiagent systems. The proposed approach uses aspect-oriented programming to separate message handling from other agent concerns, thus increasing system’s modularity and simplifying modification and expansion. To illustrate the proposed approach in practice, a prototype of a simple knowledge base agent model is implemented. The prototype is built on to...

This paper describes abstractions that have been designed to support distributed programming in the object oriented programming language BETA. The approach is minimalistic in the sense that a goal is to provide the essential building blocks on top of which other distribution related abstractions may be built. This goal is made easier by demanding for type orthogonal persistence and distribution...

According to the paradigm of Language-Oriented Programming, an application for a problem should be implemented in the most appropriate domain-specific language (DSL). This paper introduces DSL stacking, an efficient method for implementing Language-Oriented Programming where DSLs and general-purpose languages are incrementally developed on top of a base language. This is demonstrated with compo...

realm of User Interface Management Systems (UIMS) with a built-in knowledge about the specific kinds of techniques used by object-oriented databases, we have designed a system that allows a user to customize a database interface with minimal programming. Knowledge about object-oriented database constructs such as classes, groupings, etc., allows FaceKit to semi-automatically create graphical co...

Due to the data sparsity problem, social network information is often additionally used to improve the performance of recommender system. While most existing works exploit social information to reduce the rating prediction error, e.g., RMSE, a few had aimed to improve the top-k ranking prediction accuracy. This paper proposes a novel top-k oriented recommendation method, TRecSo, which incorpora...

ADOME, ADvanced Object Modeling Environment, an approach to integrating data and knowledge management based on object-oriented technology, is presented. Next generation information systems will require more exible data modelling capabilities than those provided by current object-oriented DBMSs. In particular, integration of data and knowledge management capabilities will become increasingly imp...

This article presents the definition and the implementation of the OOHQL (Object Oriented Hypermedia Query Language) on top of the OO-Navigator Framework, an object-oriented framework for developing object-oriented hypermedia applications. This language allows a final user to easily formulate queries on a hypermedia application and to obtain a set of nodes satisfying the query condition. This q...
