Economic valuation of environmental services sustained by water flows in the Yaqui River Delta

We attempted to estimate the economic value of environmental services provided by restored instream flows in the water-scarce Yaqui River Delta in Mexico. The Yaqui River begins near the U.S.-Mexico border and continues for 400 km before reaching the Oviachic dam, but has not reached the nearby Gulf of California for decades due to diversions for irrigation. These diversions have degraded the riparian ecosystem, coastal wetlands, and estuaries. Environmental services provided by restored flows in the Yaqui River would include healthy riverside vegetation, wetlands and estuaries, fish and wildlife habitats, non-use values, and recreation. A contingent valuation survey in 40 neighborhoods in the most populated Delta city, Ciudad Obregon, was administered to estimate non-market values of instream uses. Respondents were given a current and hypothetical Delta scenario (the latter assumed restored water flows in the River) and asked a willingness-to-pay (WTP) question regarding purchasing water for environmental flows through higher water bills. Results from 148 in-person interviews indicated that households would pay an average of 73 pesos monthly. WTP was found related to key variables suggested by economic theory and contingent valuation studies elsewhere: income, educational level, number of children in the household, and initial bid amount. These results will allow decision makers to compare the benefits generated by different water uses, including environmental services, and to manage scarce water resources under a long-term sustainable approach.     

What do you prefer for a relaxing time at home: reading,watching TV or listening to the radio?

This article studies the determinants of time spent by Spanish consumers on reading, watching TV and listening to the radio. To that end, we estimate a SUR (seemingly unrelated regressions) model with data from the Spanish Time Use Survey for 2009–2010. Our results show that being self-employed has a negative and significant effect on the time dedicated to reading and to watching TV; older individuals spend more time reading, and being male influences the time spent watching TV and listening to the radio, all in a statistically significant and positive way. Additionally, those with a higher level of education spend more time reading, while those with lower levels of education prefer to watch TV. Adults with better health spend less time on both reading and watching TV, and families with larger numbers of children up to age 5 tend to spend less time on all three of our at-home leisure activities. Finally, living in a larger city has a positive effect on the time dedicated to all three options.     

我国生态旅游开发中“生态保护原则”的积极性应用

在我国生态旅游开发实践中, "生态保护原则"的应用存在不完整、不积极的状况.这种现象导致的结果与生态旅游的可持续发展初衷不一致,长期看,甚至带来严重的生态破坏.对此,文章提出应积极利用生态旅游开发中的"生态保护原则",树立生态保护观念,并采取分级定等、保持生态系统完整性、保护在先开发在后等生态保护措施.     

Impact of the interactive and diagnostic uses of performance measurement systems on procedural fairness perception,cooperation and performance in supply alliances

We examine the effects of interactive and diagnostic uses of performance measurement systems (PMSs) on two behavioural factors (procedural fairness perception and cooperation) in inter-firm alliances. We further investigate whether the two behavioural factors mediate the relationship between PMS uses and alliance performance. We find that both interactive and diagnostic uses of PMS are significantly related to procedural fairness perception but only the interactive use is significantly related to cooperation. The relationships between the two uses of PMS and alliance performance are serially mediated by procedural fairness perception and cooperation. These findings contribute to management accounting studies in inter-firm alliances.     

‘Regrettable-escapism’ the negative effects of mobile app use: A retail perspective

Despite the enhanced shopping opportunities that mobile devices offer to consumers, there is a fine line between consumers enjoying the mobile shopping process and them regretting the time spent involved in it. Through the lens of Uses and Gratifications Theory (U>) and drawing on Flow Theory, this study aims to understand the effects of consumers' interactions with mobile shopping apps on their intention to reuse the app in the future, loyalty towards the brand and brand reputation. Study 1, through a questionnaire (n = 1024), provides insight into the positive and negative relationships between Utilitarian and Hedonic gratifications on intentions to reuse a retailer's mobile app, loyalty towards the b,rand and the brand's reputation. Through undertaking 24 in-depth interviews, Study 2 provides deeper insight into these relationships to uncover the complex nature of the negative effects of escapism. Findings demonstrate that the addictive nature of retailers' shopping apps lead to regrettable escapism. The flow state of mind experienced during escapism, becoming engrossed and notions of time-distortion, leave consumers with feelings of guilt and frustration due to the perceived wasted time spent on the retailer's app. Accordingly, this study advances theoretical understanding of escapism and its negative effects with ubiquitous, portable smartphones. The research provides implications for retailers and policy makers, while offering avenues for future research.
