We augment the mechanism used in Nash implementation with a political process that collects the opinions of a subset of individuals with a fixed probability distribution. The outcome is a function of only the collected opinions. We show that the necessary – and sometimes sufficient – condition for implementation by a specific political process can be either weaker or stronger than Maskin monoto...

objective: although there are some reports of reduction of obsessive-compulsive symptoms in manic episodes or its exacerbation during depressive episodes, this relationship has not been proved. method: clinical observations of six cases with co-morbidity of bipolar-i-disorder and obsessive-compulsive disorder or symptoms. results: the cases presented here show heterogeneity and variety of the r...

Present work is an attempt to describe the socio-economic status of homeless people. It was conducted in Bahir Dar city of Amhara region with objectives to identify demographic characteristics and socio-economic status of the homeless population, and to describe problems faced by homeless people. On basis of random sampling four kebeles were selected where using purposive sampling 120 homeless ...

Abstract Simple random-sampling resolutions of the raven paradox relevantly diverge from scientific practice. We develop a stratified model, yielding better fit and apparently rehabilitating simple random sampling as legitimate idealization. However, neither accommodates second concern, objection potential bias. third model that crucially invokes causal considerations, novel resolution handles ...

this paper explores the relationship between cognitive dissonance and product involvement. this project is a descriptive- mensurable research. the statistical population of this project includes all students of isfahan university in 2012-2013, and the sample volume was determined through cochran formula (354); and they were selected via stratified random sampling method. data was collected thro...

We propose a jackknife variance estimator for the population average from two, two-phase samples after imputation. The jackknife method has long been used to estimate and reduce bias, but has now become a valuable tool for variance estimation. We apply two different sampling methods, (simple random sampling and stratified random sampling) to derive jackknife variance estimators for the twosampl...

This paper’s centre of attention is on the problem of data mining (in general) and clustering (in specific) on a hidden web data. We know that data mining is a process that analyzes and extracts knowledge from large amounts of data which provides useful information to users. Hidden or deep web data is the database located at remote system .So, to access such data, we need query interface or HTM...

the current study aimed to investigate the perception of servant leadership situation and its relationship with social capial. the method is descriptive and the research project is of correlational type. the statistical population consists of all employees of the keshavarzi bank among which 196 were selected by stratified random sampling method. data were gathered through two standard questionn...

Random demodulation based compressive sampling technique is a novel approach that it can break through the Shannon sampling theorem for the sparse signal capturing. A major challenge in the random demodulation based sampling system is the random sequence generation. In this paper, we introduce an approach to generate the high-speed random sequence that meets the incoherence of compressive sampl...
