Using a nationally representative sample of 3,158 bottled water users, this article finds that both water bottle deposits and recycling laws foster recycling through a discontinuous effect that converts reluctant recyclers into diligent recyclers. The impact of the warm glow from being an environmentalist and an environmental group member is about equal to that of a 5-cent bottle deposit. Respondents from states with stringent recycling laws and bottle deposits have greater recycling rates. The efficacy of these policy interventions is greater for those who do not already recycle, have lower income, and do not consider themselves to be environmentalists. [ABSTRACT FROM AUTHOR]

Using an original, nationally representative sample of plastic water bottle users, this article examines the efficacy of various policy mechanisms to increase recycling. We evaluate the impact of bottle deposits and the stringency of a state’s recycling laws on the provision of recycling opportunities and on recycling rates. Using household-level data and controlling for the type of recycling legal regime as well as the bottle deposit policies in each state, we find that mandated separation of recyclables, the availability of a recycling center in the community, and the provision of curbside pickup at houses or recycling locations at apartments increase recycling rates. Furthermore, we show that recycling opportunities are substitutes for each other. For example, although deposits for plastic water bottles and curbside recycling separately increase recycling rates, their impacts are each less pronounced if both policies are in place. Moreover, the efficacy of these policies exhibits a discontinuous effect on household behavior, with effective laws and deposit policies transforming nonrecyclers into diligent recyclers. An examination of two states before and after their deposit laws were altered to include plastic water bottles shows that changes in recycling laws do generate changes in recycling behavior.

This paper reports the stated preference values for reducing the morbidity risks from drinking water estimated using a nationally representative U.S. sample of 3,585 households. Based on the average annual gastrointestinal (GI) illness risk in the U.S. from drinking water of about 5 illnesses per 100 population, eliminating the GI risk has a median annual value per household of $219. The considerable heterogeneity in the values arises largely from differences in attitudes towards risk and price sensitivity. Using interval regressions, we find that valuations are greater for those who perceive a high personal risk, consume a large quantity of tap water, or are environmentalists. The paper explores several methodological issues pertaining to the iterative choice format involving a choice between two policies characterized by their cost and GI risk. The analysis adjusts for starting point effects by basing valuations on the tradeoffs that are estimated to prevail at the 'equitable tradeoff rate,' which is the starting cost-water quality tradeoff rate that produces a 50-50 split in the initial policy choice between policies with greater tradeoff rates and policies with lower tradeoff rates. The heterogeneity in valuations is also explored by examining quantile regression results and the determinants of the unbounded valuation amounts at the low and high extremes. [ABSTRACT FROM AUTHOR]

The article presents a study that investigates the political economy preferences of voters with regard to the environment using a new stated preference survey that shows the first benefit values for national water quality levels in the U.S. It cites that the mean valuation greatly surpasses the median value, as the distribution of valuations is highly not aligned. The study matches the valuations of the survey with the information on the patterns of respondent voting. Moreover, the results show that preferences of registered voters are the same to the preferences of the population at large, however, median voters highly regard the water quality more than nonvoters. It notes that the strongest contrast of voter-weighted preferences is from voters with different candidates.

Based upon trends in observed climate, extreme events are thought to be increasing in frequency and/or magnitude. This change in extreme events is attributed to enhancement of the hydrologic cycle caused by increased greenhouse gas concentrations. Results are presented of relatively long (50 yr) regional climate model simulations of the western United States examining the sensitivity of climate and extreme events to a doubling of preindustrial atmospheric CO2 concentrations. These results indicate a shift in the temperature distribution, resulting in fewer cold days and more hot days; the largest changes occur at high elevations. The rainfall distribution is also affected; total rain increases as a result of increases in rainfall during the spring season and at higher elevations. The risk of flooding is generally increased, as is the severity of droughts and heat waves. These results, combined with results of decreased snowpack and increased evaporation, could further stress the water supply of the western United States. [ABSTRACT FROM AUTHOR]

Using a regional climate model (RegCM2.5), the potential impacts on the climate of California of increasing atmospheric CO2 concentrations were explored from the perspective of the state's 10 hydrologic regions. Relative to preindustrial CO2 conditions (280 ppm), doubled preindustrial CO2 conditions (560 ppm) produced increased temperatures of up to 4°C on an annual average basis and of up to 5°C on a monthly basis. Temperature increases were greatest in the central and northern regions. On a monthly basis, the temperature response was greatest in February, March, and May for nearly all regions. Snow accumulation was significantly decreased in all months and regions, with the greatest reduction occurring in the Sacramento River region. Precipitation results indicate drier winters for all regions, with a large reduction in precipitation from December to April and a smaller decrease from May to November. The result is a wet season that is slightly reduced in length. Findings suggest that the total amount of water in the state will decrease, water needs will increase, and the timing of water availability will be greatly perturbed. [ABSTRACT FROM AUTHOR]

In this study a regional climate model is employed to expand on modeling experiments of future climate change to address issues of 1) the timing and length of the growing season and 2) the frequency and intensity of extreme temperatures and precipitation. The study focuses on California as a climatically complex region that is vulnerable to changes in water supply and delivery. Statistically significant increases in daily minimum and maximum temperatures occur with a doubling of atmospheric carbon dioxide concentration. Increases in daily temperatures lead to increases in prolonged heat waves and length of the growing season. Changes in total and extreme precipitation vary depending upon geographic location.

Objectives: The diagnosis and treatment of Chlamydia trachomatis infection is important in preventing persistent or recurrent infection. Expedited partner therapy (EPT) is the favoured and supported method for STI treatment of the Centers for Disease Control and Prevention when the provider cannot be assured that all recent sexual partner(s) will seek therapy. EPT is legally permissible in 38 states and is endorsed by healthcare organisations to decrease the rates of chlamydia and gonorrhoea infection. Our study investigated the impact of EPT legal status (permissible, potentially allowable or prohibited) on C. trachomatis infection rates for each state., Methods: Our ecological study modelled the number of reported chlamydia cases from 2000 to 2013 as a function of year, legal status and the interaction between year and legality. We used a negative binomial regression model that included state fixed effects (including the District of Columbia) to account for both the repeated measures per state and state-specific characteristics that could not be measured for inclusion in this study. The lagged number of C. trachomatis cases was included as a covariate and each state's total population for a given year was included in the model as an exposure parameter. States were designated Y (EPT permissible), N (EPT prohibited) and M (EPT potentially allowable), and the legal status of each state could vary over time., Results: Each legal category saw an increase in the incidence rate of C. trachomatis infection, but on average, the incidence rate for states with prohibitive EPT legislation grew significantly faster over time compared with the rate for the states where EPT was permissible. The average increase in predicted incidence rates per year for states with Y , N and M legal status were 14.1 (95% CI (12.0 to 16.2)), 17.5 (95% CI (15.9 to 19.2)) and 16.8 (95% CI (15.0 to 18.6)) cases per 100 000 persons per year, respectively, when controlling for state-specific effects., Conclusions: Our model suggests that a lack of EPT legislation is associated with an increase in STI rates. States with potentially allowable EPT legislation as of 2013 (n=8) should consider permitting EPT as a component of a multipronged strategy for treatment of sexual partners to prevent C. trachomatis infection., Competing Interests: Competing interests: None declared., (Published by the BMJ Publishing Group Limited.

This article evaluates the effect of the choice of survey recruitment mode on the value of water quality in lakes, rivers, and streams. Four different modes are compared: bringing respondents to one central location after phone recruitment, mall intercepts in two states, national phone-mail survey, and an Internet survey with a national, probability-based panel. The modes differ in terms of the representativeness of the samples, non-response rates, sample selection effects, and consistency of responses. The article also shows that the estimated value of water quality can differ substantially depending on the survey mode. The national Internet panel has the most desirable properties with respect to performance on the four important survey dimensions of interest.
