Quantifying urban forest structure, function, and value: the Chicago Urban Forest Climate Project

Abstract: This paper is a review of research in Chicago that linked analyses of vegetation structure with forest functions and values. During 1991, the regions trees removed an estimated 5575 metric tons of air pollutants, providing air cleansing worth 9.2 million. Each year they sequester an estimated 315 800 metric tons of carbon. Increasing tree cover 10% or planting about three trees per building lot saves annual heating and cooling costs by an estimated 50 to 90 per dwelling unit because of increased shade, lower summertime air temperatures, and reduced neighborhood wind speeds once the trees mature. The net present value of the services trees provide is estimated as 402 per planted tree. The present value of long-term benefits is more than twice the present value of costs.

Primary sources of health information: comparisons in the domain of health attitudes, health cognitions, and health behaviors

Abstract: The recent growth in consumer autonomy in health care accompanied by the surge in the use of new media for health information gathering has led to an increasing scholarly interest in understanding the consumer health information search construct This article explores consumer health information seeking in the realm of the primary sources of health information used by consumers Based on an analysis of the 1999 HealthStyles data, the paper demonstrates that active communication channels such as interpersonal communication, print readership, and Internet communication serve as primary health information sources for health-conscious, health-information oriented individuals with strong health beliefs, and commitment to healthy activities On the other hand, passive consumption channels such as television and radio serve as primary health information resources for individuals who are not health-oriented Media planning implications are drawn from the results, suggesting that broadcast outlets with an entertainment orientation are better suited for prevention campaigns Such channels provide suitable sites for entertainment-education On the other hand, print media, interpersonal networks, and the Internet are better suited for communicating about health issues to the health-active consumer segment

Centrality Dependence of the Charged-Particle Multiplicity Density at Midrapidity in Pb-Pb Collisions at root s(NN)=2.76 TeV

Abstract: The centrality dependence of the charged-particle multiplicity density at midrapidity in Pb-Pb collisions at root s(NN) = 2: 76 TeV is presented. The charged-particle density normalized per participating nucleon pair increases by about a factor of 2 from peripheral (70%-80%) to central (0%-5%) collisions. The centrality dependence is found to be similar to that observed at lower collision energies. The data are compared with models based on different mechanisms for particle production in nuclear collisions.
