In this paper, we present an empirical study of the opinion dynamics a large-scale sample online social network users. We estimate opinions users as continuous scalars based on their subscriptions to information sources and analyze how friendship connections affect these estimations. Distinguishing between positive (toward friends) negative (away from shifts, find that existence magnitude shift...

ORGANIZATIONAL CULTURE, MACRO AND MICRO EMPOWERMENT DIMENSIONS, AND JOB SATISFACTION: AN APPLICATION OF CONCURRENT MIXED AND MULTI-LEVEL METHODS IN THE FEDERAL SECTOR Timothy L. Bailey, Ph.D. Touro University International 2009 This dissertation examined the interrelationship of organizational culture; macro (structural) and micro (psychological) empowerment; and job satisfaction. Specifically,...

because of its kinetic nature and computational advantages, the lattice boltzmann method (lbm) has been well accepted as a useful tool to simulate micro-scale flows. the slip boundary model plays a crucial role in the accuracy of solutions for micro-channel flow simulations. the most used slip boundary condition is the maxwell slip model. the results of maxwell slip model are affected by the ac...

the paper presents an analysis of both energy intensity and energy demand for the italianindustrial sector. the aim of the paper is twofold: making a decomposition of energy intensity at the aggregate level and modeling energy demand at the firm level. the decomposition of energy intensity shows different patterns for the different sub-sectors in the period of interest. in the micro approach, p...

We use micro data on product prices linked to information on the firms that set them to test for selection effects (state dependence) in micro-level producer pricing. In contrast to using synthetic data from a canonical menu-cost model, we find very weak, if any, micro-level selection effects when running price change probability regressions on actual data. Moreover, when fitting a model that n...

Accurate loss reserves are essential for insurers to maintain adequate capital and to efficiently price their insurance products. Loss reserving for Property & Casualty (P&C) insurance is usually based on macro-level models with aggregate data in a run-off triangle but many limitations exist in these models despite of their simplicity. A run-off triangle is a summary of underlying individual cl...

this research is aimed at developing a model for measuring and comparison amount of supply and demand for different urban services from quality of life and equity perspectives, in urban built-up areas. this paper explains different steps of implementing the model as a tool for evaluating accessibility of residents to various services according to two main criteria: land per capita and distance ...
