Patients' self-concept, desire for information and uncertainty reduction
… is a post-test only experimental design using an uncertainty reduction video to alleviate patient uncertainty, desire for information and increase self-concept to improve overall patient satisfaction with health care experience. The subjects were 80 cardiac consultation patients in a cardiology …

Uncertainty Reduction in Initial Interaction of Collectivist and Individualist Students
… interviews, to investigate the feelings of uncertainty of six international students within their first three semesters at a medium-sized university in the Midwestern United States. Participants described their feelings of uncertainty about: )a anticipated initial interactions in a new …

Depersonalization and Projection in Groups: Two Paths to Uncertainty Reduction
… model, which proposes that uncertainty reduction is a key motivation underlying depersonalization and projection processes in groups. The proposed model describes the conditions under which people in group contexts define themselves in terms of group attributes …

Uncertainty Quantification and Uncertainty Reduction Techniques for Large-scale Simulations
… It is of great interest to include uncertainty information in the simulation. By ``Uncertainty Quantification,'' we denote the ensemble of techniques used to model probabilistically the uncertainty in model inputs, to propagate it through the system, and to represent the resulting …

Utilization of soft data for uncertainty reduction in groundwater flow and transport modeling
Includes bibliographical references (pages 237-247).

Robust State Estimation, Uncertainty Quantification, and Uncertainty Reduction with Applications to Wind Estimation
… method, known as Sensitivity-Informed Variable Reduction (SIVR) was developed. In the multivariate case presented here, gPC and the SIVR-derived reduced gPC (gPCr) exhibit a computational advantage over Monte Carlo sampling-based methods for uncertainty quantification (UQ) and sensitivity …

A new optimisation procedure for uncertainty reduction by intelligent wells during field development planning
The uncertainty in the produced oil volume can be minimised by substituting intelligent wells (IWs) for conventional wells. A previous study showed that IWs reduce the impact of geological uncertainty on the production forecast (Birchenko, Demyanov et al. 2008). This investigation has now been …

Iterative uncertainty reduction via Monte Carlo simulation : a streamlined life cycle assessment case study
… intuition. While they can be effective, the reduction in effort is often accompanied by a commensurate increase in the uncertainty of the results. One nascent streamlining method aims to reduce uncertainty by generating random simulations of the target product's environmental impact. In these …

Uncertainty reduction in reservoir parameters prediction from multiscale data using machine learning in deep offshore reservoirs.
… a model. Also increasing the degree of this uncertainty is the fact that the reservoir properties from different data sources - like well logs, cores and well test - often produce different results, thus making predictions less accurate. The present study focussed on three reservoir …

Organizational Information-Seeking in the Digital Era: A Model of New Media Use, Uncertainty Reduction, Identification and Culture
… between information-seeking behaviors, uncertainty level serves as a mediator, and tests the mediating model of information-seeking, uncertainty level and identification levels. In particular, this dissertation highlights the role of social contexts in individuals’ daily interactions. It …

Making Us Look Bad vs. Making Us Uncertain: Examining the Motivations Underlying Derogation of Ingroup Deviants
… social identity motives—self-esteem and uncertainty reduction—underlie the derogation of these different types of group deviants. Specifically, it was predicted that self-esteem is the primary motivation for the derogation of generic norm deviants, whereas, uncertainty reduction is the …

Uncertainty budgeting methods for conceptual aircraft design
Quantification and management of uncertainty are critical in the design of engineering systems, especially in the early stages of conceptual design. This thesis presents an approach to defining budgets on the acceptable levels of uncertainty in design quantities of interest, such as the allowable …

A Descriptive Analysis of the Miscues Associated With the Construction of Meaning by Three Bilingual Spanish-English-Speaking Students Reading in Their Second Language, English
… strategies they employed, as well as the uncertainty reduction they effected, were observed.

How firms learn about new product development in their business networks
… the network learning mechanism impact on NPD uncertainty reduction and speed-to-market? Two complementary research approaches to explore empirical phenomena and to examine the proposed constructs were envisaged: the qualitative multiple-case study guided and refined theory development; and the …

Probablistic risk analysis of financial investment decisions. A probabilistic analysis of the financial performance of'selected Colombian companies and banks for the period 1973-1977 with application to the investment decision process.
… developed for assessing risk and reducing uncertainty inherent in the investment decision making process. It is proposed that the two most important profitability financial ratios in relation to investment decisions are the return on equity and the return on assets respectively. In order to …

The negotiation of conflict management in long-distance and geographically close romantic relationships.
… close dating relationships (GCDRs). Uncertainty Reduction Theory posits that uncertainty could be problematic for LDDRs and thus contribute to differences in conflict management styles. This study applied the conceptualization of Peterson's (1983) conflict management strategies to the …
