In this paper, we address the often contentious debate over state and local recycling policy by carefully estimating the social net benefit of curbside recycling. Benefits are estimated using household survey data from over 4,000 households across 40 western U.S. cities. We calibrate household willingness-to-pay for hypothetical bias using an innovative experimental design that contrasts stated...

Cost-benefit analysis was conducted to determine whether it is worthwhile to initiate a routine varicella vaccination program in Taiwan from different perspectives. Using the human capital approach, the discounted net cost for vaccination program was New Taiwan Dollars (NTD) 281 million from health care payer's perspective. Taking indirect costs into account, the net saving due to vaccination p...

[1] We describe a method for determining net annual biological oxygen production in the euphotic zone of the ocean using remote in situ measurements of oxygen and nitrogen gas. Temperature, salinity, oxygen, and total dissolved gas pressure were measured every 2 hours at 10-m depth on a mooring at the Hawaii Ocean time series during the year 2005. Since dissolved N2 is effectively inert to biol...

Generational accounting is a relatively new method of reorganizing the government's budget data to understand how the burden of paying for government spending on goods and services is distributed among living and future generations.' To study this distribution, generational accounting estimates lifetime net tax rates facing different generations under current policies.' For a given generation, ...

background: use of bed-net continues to offer potential strategy for malaria prevention in endemic areas. local communi­ties are indispensable during design and implementation stages. methods: a cross-sectional study of 192 randomly selected inhabitants was carried out in malarious zone, siahoo dire­strict, hormozgan province, southern iran. in addition, we monitored human landing periodicity o...

A universal deterministic inhibitor Petri net with 14 places, 29 transitions and 138 arcs was constructed via simulation of Neary and Woods’ weakly universal Turing machine with 2 states and 4 symbols; the total time complexity is exponential in the running time of their weak machine. To simulate the blank words of the weakly universal Turing machine, a couple of dedicated transitions insert th...
