Vertical Greening

Abstract There are numerous buildings in existing residential areas in Hangzhou City, which results in much carbon emissions and the formation of greenhouse gases that have exerted significant ad-verse impacts on the living comfort of citizens in Hangzhou City. It is imperative to conduct a greening renovation of buildings in existing residential areas in Hangzhou City. Vertical greening, as a significant measure of renovation, has received much attention. In this paper we use double-bounded discrete choice format to elicit public’s willingness to pay (WTP), and the economic benefits of vertical greening reduces greenhouse gases in Hangzhou City were preliminarily estimated, and the factors that affect residents' payment and participation. A total of 1089 valid samples were obtained via the face-to-face field interview. There were 250 (23.0%) respondents who refused to pay, whose data were subject to processing with Spike model, which had been proved to be more advantageous than traditional models in dealing with zero response problems. Families in Hangzhou City would pay 702.55 Chinese yuan (CNY) each year. The economic benefit of the project is 1.141–1.433 billion CNY. The factors affecting WTP were explored by demographic characteristics,social psychology༌knowledge of the environment and theory of planned behavior. The results showed that there were obvious statistical relationships between the age, income, family members, cognition of vertical greening and subjective norms of respondents and their WTP. Meanwhile, the feedback information was collected and analyzed, with the results showing that increasing income, setting up compensation mechanism, promoting the publicity of environmental protection, and disclosing the flow of funds would conduce to residents' participation in the renovation of vertical greening.

Walking is an essential sustainable mode of transportation. Encouraging to increase walking trips can bring various social and economic benefits to our society. Since the policy paradigm has been shifting from car-oriented to pedestrian-oriented, interest in securing pedestrian rights and improving walking environments is increasing significantly. This study aims to examine factors affecting pedestrian satisfaction according to land use and street type. A pedestrian satisfaction survey was conducted in an industrial city with a mid-size population in the city of Changwon, South Korea. Based on the survey data from 500 respondents, factors affecting pedestrian satisfaction were analyzed by land use (commercial or residential areas) and street type (non-separated or separated sidewalks). The analysis results, using binary and ordered logit models, showed that the less illegal parking, the more pedestrian space, pedestrian guidance facility, and green space, the higher the pedestrian satisfaction. Factors positively affecting the satisfaction of pedestrian paths according to land use were physical environmental variables, such as the separated sidewalk variable. In commercial areas, pedestrian guidance facilities and street cleanliness were included as major influencing factors, implying differences in land use influencing factors. A common factor affecting the satisfaction of separated or non-separated sidewalk cases was also identified as the sufficiency of walking space. Therefore, the most urgent policy measure for improving pedestrian satisfaction for the city was to install a sidewalk or expand the pedestrian space. In the pedestrian-vehicle separation models, green space and cleanliness were included as significant variables, and in the non-separated models, variables of pedestrian guidance facilities and sidewalk conditions were included.

The Cost

Abstract Introduction Trial-based tele-obstructive sleep apnea (OSA) cost-effectiveness analyses have often been inconclusive due to small sample sizes and short follow-up. In this study, we report the cost-effectiveness of Tele-OSA using a larger sample from a 3-month trial that was augmented with 2.75 additional years of epidemiologic follow-up. Methods The Tele-OSA study was a 3-month randomized trial conducted in Kaiser Permanente Southern California that demonstrated improved adherence in patients receiving automated feedback messaging regarding their positive airway pressure (PAP) use when compared to usual care. At the end of the 3 months, participants in the intervention group pseudo-randomly either stopped or continued receiving messaging. This analysis included those participants who had moderate-severe OSA (Apnea Hypopnea Index >=15) and compared the cost-effectiveness of 3 groups: 1) no messaging, 2) messaging for 3 months only, and 3) messaging for 3 years. Costs were derived by multiplying medical service use from electronic medical records times costs from Federal fee schedules. Effects were average nightly hours of PAP use. We report the incremental cost per incremental hour of PAP use as well as the fraction acceptable. Results We included 256 patients with moderate-severe OSA (Group 1, n=132; Group 2, n=79; Group 3, n=45). Group 2, which received the intervention for 3 months only, had the highest costs and fewest hours of use and was dominated by the other two groups. Average 1-year costs for groups 1 and 3 were $6035 (SE, $477) and $6154 (SE, $575), respectively; average nightly hours of PAP use were 3.07 (SE, 0.23) and 4.09 (SE, 0.42). Compared to no messaging, messaging for 3 years had an incremental cost ($119, p=0.86) per incremental hour of use (1.02, p=0.03) of $117. For a willingness-to-pay (WTP) of $500 per year ($1.37/night), 3-year messaging has a 70% chance of being acceptable. Conclusion Long-term Tele-OSA messaging was more effective than no messaging for PAP use outcomes but also highly likely cost-effective with an acceptable willingness-to-pay threshold. Epidemiologic evidence suggests that this greater use will yield both clinical and additional economic benefits. Support (if any) Tele-OSA study was supported by the AASM Foundation SRA Grant #: 104-SR-13

The Impact

AbstractMillennials, the demographic cohort born in the last two decades of the twentieth century, are reported to adopt information and communication technologies (ICTs) in their everyday lives, including travel, to a greater extent than older generations. As ICT-driven travel-based multitasking influences travelers’ experience and satisfaction in various ways, millennials are expected to be affected at a greater scale. Still, to our knowledge, no previous studies have specifically focused on the impact of travel multitasking on travel behavior and the value of travel time (VOTT) of young adults. To address this gap, we use an original dataset collected among Northern California commuters (N = 2216) to analyze the magnitude and significance of individual and household-level factors affecting commute mode choice. We estimate a revealed-preference mode choice model and investigate the differences between millennials and older adults in the sample. Additionally, we conduct a sensitivity analysis to explore how incorporation of explanatory factors such as attitudes and propensity to multitask while traveling in mode choice models affects coefficient estimates, VOTT, and willingness to pay to use a laptop on the commute. Compared to non-millennials, the mode choice of millennials is found to be less affected by socio-economic characteristics and more strongly influenced by the activities performed while traveling. Young adults are found to have lower VOTT than older adults for both in-vehicle (15.0% less) and out-of-vehicle travel time (15.7% less), and higher willingness to pay (in time or money) to use a laptop, even after controlling for demographic traits, personal attitudes, and the propensity to multitask. This study contributes to better understanding the commuting behavior of millennials, and the factors affecting it, a topic of interest to transportation researchers, planners, and practitioners.

Green roofs reduce runoff from impervious surfaces in urban development. This paper reviews the technical literature on green roof hydrology. Laboratory experiments and field measurements have shown that green roofs can reduce stormwater runoff volume by 30 to 86%, reduce peak flow rate by 22 to 93% and delay the peak flow by 0 to 30 min and thereby decrease pollution, flooding and erosion during precipitation events. However, the effectiveness can vary substantially due to design characteristics making performance predictions difficult. Evaluation of the most recently published study findings indicates that the major factors affecting green roof hydrology are precipitation volume, precipitation dynamics, antecedent conditions, growth medium, plant species, and roof slope. This paper also evaluates the computer models commonly used to simulate hydrologic processes for green roofs, including stormwater management model, soil water atmosphere and plant, SWMS-2D, HYDRUS, and other models that are shown to be effective for predicting precipitation response and economic benefits. The review findings indicate that green roofs are effective for reduction of runoff volume and peak flow, and delay of peak flow, however, no tool or model is available to predict expected performance for any given anticipated system based on design parameters that directly affect green roof hydrology.

PurposeThe purpose of this paper is to empirically analyze the factors affecting Muslim consumers’ willingness to pay (WTP) for Halal food, products and operations by employing theory of reasoned action.Design/methodology/approachThis study has used quantitative research methodology and collected data from 350 questionnaires from a densely populated city of Pakistan. Partial least squares-structural equation modeling was used to analyze the data.FindingsThe results show that the concerns about Halal, religiosity, perception of usefulness of Halal and product ingredients have a significant impact on WTP for Halal foods, while attitude has an insignificant impact on WTP. Moreover, the extent of demand for Halal certification is significantly affected by WTP.Originality/valueThe study highlighted the concerns of the Muslim consumers with respect to Halalness of the products and operations despite living in a Muslim country. It is recommended that the policy makers, food authorities and health institutions should conduct regular inspections of foods, products and producers’/manufacturers’ operations to ensure that all the procedures from manufacturing of the raw material till the finished goods follow Islamic principles to make them completely Halal.

Purpose The purpose of this paper is to examine citizens’ willingness to pay (WTP), in relation to having a professional first-tier football club in a medium-sized Danish municipality, when tangible economic benefits such as economic growth and/or inbound migration produced by these are absent. Design/methodology/approach Using the contingent valuation method on survey respondents, the study examines factors affecting WTP using binary logistic regression and interval regression and further extrapolates the WTP from the sample to the municipal population. Findings Citizens significantly value having a first-tier football club in their municipality even when tangible benefits are absent, although a large proportion of respondents stated to be against the municipality being financially involved in professional team sports clubs (PTSC). WTP is largely driven by interest in sports and the local football club. It is argued that the findings cannot be generalized across contexts. Research limitations/implications There can be circumstances where public subsidy of PTSCs is beneficial to economic welfare. However, authorities should be careful in their evaluation of whether to subsidize PTSCs. Originality/value The study expands on existing research by informing respondents about the lack of tangible benefits produced by PTSCs, hereby focusing on WTP on an informed basis.

Abstract In this paper, we analyze perceptions and determinants of households' participation in a randomized experiment on water quality testing and information in southern Ghana. Beneficiary households assessed the components of the intervention including its relevance and adequacy in improving understanding of water quality issues. Motivating and constraining factors to participation in the randomized experiment are also assessed. We also estimate the correlates of participation in the intervention. Social and economic benefits derived from the intervention based on perceptions are compared with impacts of the intervention using an instrumental variable approach. We found evidence that subjective analysis estimates of the effects of the intervention are higher than the objective analysis estimates. Households generally perceived the intervention to be relevant in improving their understanding of water quality issues. However, there are differing opinions based on random assignment into either child or adult treatment groups on most- and least-liked attributes of the intervention, and also motivating and constraining factors affecting participation in the intervention. The factors that statistically and significantly influenced participation in the intervention include educational attainment, ethnicity, religious denomination and marital status of the household heads, in addition to the location of residence.

Energy Consumption Pattern

Energy consumption pattern and greenhouse gases emission are interrelated. The unsustainable use of biomass and widespread use of commercial energy are of the major sources of greenhouse gas emission. The alternative to kerosene for lighting is solar home system (SHS), which is one of the potential renewable technologies for rural electrification. The present study has analyzed household energy consumption pattern and greenhouse gases emission from energy consumption practices as well as environmental and economic benefits of SHS in Madi Kalyanpur Village Development Committee of Chitwan district. For the purpose, the primary data were collected through household questionnaire survey, key informant interview (KII) and focus group discussion (FGD). The analysis has shown that 22% of household use all types of energy, i.e. fuel-wood, LPG (liquefied petroleum gas), biogas and SHS as the sources of energy. Thirty-five percent households use fuel-wood, LPG and SHS, 24% use fuel-wood, biogas and SHS, 1% used LPG and SHS, 5% use biogas and SHS, 4% use LPG, biogas and SHS and 9% use fuel-wood and SHS as a source of energy. Almost all people have been using SHS for the lighting purpose. The average annual greenhouse gases emission per household from fuel-wood and liquefied petroleum gas consumption was 7.89 ton and 0.17 ton of CO2 equivalent respectively. Typically, a 40 Wp SHS reduced the consumption of kerosene by 42 liter annually for lighting that displaced 0.11 ton of CO2 equivalent per household per year. The simple payback period for typically 40 Wp SHS was found to be nine years with no subsidy, seven years with subsidy from Alternative Energy Promotion Centre and two years with Indian Government Grant. Similarly, the benefit-cost ratios were found to be 3.1, 3.5 and 4.6 for the systems with no subsidy, with AEPC subsidy and with Indian Grant, respectively.
