We study effects on the W mass measurements at LEP2 from non-perturbative interference effects in the fully hadronic decay channel. Based on a model for Bose-Einstein interference, which is in agreement with LEP1 data, we argue that there are no Bose-Einstein correlations between bosons coming from the different W’s. For small reconnection probabilities we rule out the possible experimental sig...

BACKGROUND The 'Communicate to vaccinate' (COMMVAC) project builds research evidence for improving communication with parents and communities about childhood vaccinations in low- and middle-income countries. Understanding and mapping the range of vaccination communication strategies used in different settings is an important component of this work. In this part of the COMMVAC project, our objec...

We study interference effects between resonant and nonresonant amplitudes for the γγ → W + W − process at a backscattered photon-photon collider. We show that a Higgs boson with M H > ∼ 200 GeV is manifest as a resonant dip in the W + W − invariant mass spectrum and we investigate its statistical significance. There has been recent interest in weak gauge boson pair production in γγ collisions a...

An on-line mass spectrometric method has been developed to generate and identify drug metabolites formed by hepatic cytochromes P450. This method, pulsed ultrafiltration-mass spectrometry, may be used for rapid screening of drugs to determine their extent of metabolism by microsomal cytochromes P450 and to characterize the primary metabolites. Rat liver microsomes were trapped in a stirred ultr...

Ana akımın en tanınmış ve en önemli iki aydınının iletişim alanında en önemli klasik yapıtlarından biri de Mass Communication, Popular Taste and Organized Action yapıtıdır. Lazarsfeld iletişimde ampirik yöntemin gelişmesinde ve yönetimsel araştırmanın yaygınlaşmasında öncülük etmiştir. Merton, T. Parsons’un yapısal fonksiyonalizmini geliştiren Amerikan ana akım sosyolojisinin önemli liderlerind...

Revolution dynamics is studied through a minimal Ising model with three main influences (fields): personal conservatism (power-law distributed), inter-personal and group pressure, and a global field incorporating peer-to-peer and mass communications, which is generated bottom-up from the revolutionary faction. A rich phase diagram appears separating possible terminal stages of the revolution, c...

The large-scale adoption of computer mediated communication technologies has resulted in what has been described as “mass interaction”, shared discourse between hundreds, thousands or more individuals. The emergence of mass interaction presents new opportunities to learn about and understand human communication, and information technologies. A number of theoretical papers suggest that the forms...

This article provides an overview of the ways in which mass communication has been used -- or can be used -- to promote beneficial changes in behavior among members of populations. We use an ecological perspective to examine the ways in which mass media interventions can be used to influence public behavior both directly and indirectly. Mass media interventions that seek to influence people dir...

The risk of incidents involving mass decontamination in response to a chemical, biological, radiological, or nuclear release has increased in recent years, due to technological advances, and the willingness of terrorists to use unconventional weapons. Planning for such incidents has focused on the technical issues involved, rather than on psychosocial concerns. This paper presents a novel exper...
