the occurrence of chatter vibrations in boring operation has a great influence in improving workpiece dimensional accuracy, surface quality and production efficiency. in this paper instability analysis of machining process is presented by dynamic model of boring machine. this model, which consists of machine tool’s structure, is provided by finite element method and ansys software. the model is...

This study examines the impact of legitimacy on the dynamics of interorganizational networks within the nongovernmental organizations’ children’s rights community. The 27-year period of analysis included a critical community event: the ratification of the United Nations Convention on the Rights of the Child (UNCRC). Building on theories of organizational evolution, hypotheses proposed that (1) ...

Normative dimensions constitute one of the important elements in the Theory of Reasoned Action (TORA) model. However, the changes of lifestyle over period and different societies have spurred the TORA model constitution and also to vary interpretation of the model itself towards intention to purchase the green food product.Therefore, this paper aims to explorethe underlying dimensionsof normati...

The authors look at online tip exchanges as parts of gift economies created by the players and designers of console and online role-playing games in Taiwan. A group of experienced players and tip contributors agreed to be interviewed about the mechanisms and processes of providing free strategy guides on the Internet. Their comments reveal needs for social approval and networking in addition to...

This study examined the processing correlates of aspectual coercion among native and non-native speakers of English. For native English speakers, results suggested that the processing delay associated with aspectual coercion is minimal. Aspectual coercion was perhaps cognitively easy to perform. By contrast, non-native speakers of English from unlike first language (L1) backgrounds differed in ...

Branching Constraint Satisfaction Problems (BCSPs) have been introduced to model dynamic resource allocation subject to constraints and uncertainty. We give BCSPs a formal probability semantics by showing how they can be mapped to a certain class of Bayesian decision networks.

This paper exposes the results of our participation at INEX’07 in the AdHoc track and the comparison of these results with respect to the ones obtained last year. Three runs were submitted to each of the Focused, Relevant In Context and Best In Context tasks, all of them obtained with Garnata, our Information Retrieval System for structured documents. As in the past year, we use a model based o...

Prior research has found mixed evidence for the long-theorized link between religiosity and pro-social behavior. To help overcome this divergence, I hypothesize that pro-social behavior is linked not to religiosity per se, but rather to the salience of religion and religious norms. I report a field experiment that examined when auction participants will respond to an appeal to continue bidding ...

Real-time Decision algorithms are a class of incremental resource-bounded [Horvitz, 89] or anytime [Dean, 93] algorithms for evaluating influence diagrams. We present a test domain for real-time decision algorithms, and the results of experiments with several Real-time Decision Algorithms in this domain. The results demonstrate high performance for two algorithms, a decision-evaluation variant ...
