Linking place preferences with place meaning: An examination of the relationship between place motivation and place attachment 总被引:4,自引:0,他引:4
Using data collected from residents surrounding a large urban park setting, we examined the relationship between their motivation to visit the park and their attachment to the setting. Based on the literature suggesting that natural environments provide humans with a variety of desired psychological, social, and physiological outcomes, we hypothesized that these outcomes would motivate respondents to interact with the park environment and facilitate the development of their attachment to the setting. Our data were analysed using covariance structure analysis. The results of this analysis offered partial support for our hypothesized model. Using multidimensional conceptualizations of motivation and place attachment, we observed that not all dimensions of motivation had a significant effect on the dimensions of place attachment. The valence of the significant predictors, however, was consistent with our hypotheses and prior literature. 相似文献

/ Current private and public regulatory systems may not provide an optimal degree of regulation for labels bearing environmental information, and established institutions may detract from efforts to provide for better environmental management. The advent of ISO 14000 offers new opportunities for making eco-labeling a meaningful tool to encourage environmental stewardship. While new federal legislation offers the best vehicle to introduce these standards into US law, the slow pace of the legislative process may recommend an alternative system. Multinational and civic-minded firms may be expected to employ private programs to nurture benevolent environmental management practices until more definitive governmental institutions can be put in place.KEY WORDS: Eco-labels; Environmental labeling; International standards; ISO 14000 相似文献

Model‐Based Nitrogen and Phosphorus (Nutrient) Criteria for Large Temperate Rivers: 2. Criteria Derivation 下载免费PDF全文

Nitrogen and phosphorus criteria were developed for 233 km of the Yellowstone River, one of the first cases where a mechanistic model has been used to derive large river numeric nutrient criteria. A water quality model and a companion model which simulates lateral algal biomass across transects were used to simulate effects of increasing nutrients on five variables (dissolved oxygen, total organic carbon, total dissolved gas, pH, and benthic algal biomass in depths ≤1 m). Incremental increases in nutrients were evaluated relative to their impact on predefined thresholds for each variable; the first variable to exceed a threshold set the nutrient criteria. Simulations were made at a low flow, the 14Q5 (lowest average 14 consecutive day flow, July‐September, recurring one in five years), which was derived using benthic algae growth curves and EPA guidance on excursion frequency. An extant climate dataset with an annual recurrence was used, and tributary water quality and flows were coincident with the river's 10 lowest flow years. The river had different sensitivities to nutrients longitudinally, pH being the most sensitive variable in the upstream reach and algal biomass in the lower. Model‐based criteria for the Yellowstone River are as follows: between the Bighorn and Powder river confluences, 55 μg TP/l and 655 μg TN/l; from the Powder River confluence to Montana state line, 95 μg TP/l and 815 μg TN/l. Pros and cons of using steady‐state models to derive river nutrient criteria are discussed. 相似文献

Microorganisms are ubiquitous in natural environments and in water supply infrastructure including groundwater wells. Sessile-state microorganisms may build up on well surfaces as biofilms and, if excessive, cause biofouling that reduces well productivity and water quality. Conditions can be improved using biocides and other traditional well rehabilitation measures; however, biofilm regrowth is inevitable given the continuous introduction of microorganisms from the surrounding environment. Alternative and less invasive well maintenance approaches are desirable for reducing biofilm densities while also minimizing harmful disinfection-by-products. The primary objective of this research was to evaluate effectiveness of alternative treatments for inactivating microorganisms comprising biofilms. A novel approach was designed for in situ growth of biofilms on steel coupons suspended from ‘chandeliers’. After more than 100 days of in situ growth, biofilms were harvested, sampled, and baseline biofilm densities quantified through cultivation. Ultraviolet-C (UV-C) and oxidative treatments including hydrogen peroxide (H2O2), ozone (O3) and mixed oxidants were then applied to the biofilms in laboratory-scale treatments. Microbial inactivation was assessed by comparing treated versus baseline biofilm densities. H2O2 was the most effective treatment, and decreased density below baseline by as much as 3.1 orders of magnitude. Mixed oxidants were effective for the well having a lower density biofilm, decreasing density below baseline by as much as 1.4 orders of magnitude. Disparity in the response to treatment was apparent in the wells despite their spatial proximity and common aquifer source, which suggests that microbiological communities are more heterogeneous than the natural media from which they originate. 相似文献

Cetacean-focused tourism in Taiwan has grown rapidly since 1997. This development, measured in terms of both number of tour
boats and visitors, has resulted in many resource management challenges stemming from the absence of regulation and scientific
data. To fill this void in empirical evidence, we used 464 sighting records from 2002 to 2005 to model the impact of cetacean-focused
tourism. Cox proportional hazard analysis indicated cetacean avoidance responses to cetacean watching boats were strongly
associated with pod size, mother–calf pairs, and cetacean-vessel distances. Mother–calf pairs abandoned their avoidance tactic
by 55% compared to noncalf groups when tour boats approached. Second, the hazard ratio of abundance was 0.996, suggesting
that the odds of encountering avoidance responses by the cetaceans decreased by 42% for every 100-member increase in the cetacean
pod size. Last, distances maintained by boats from the cetaceans was positively related to avoidance responses (i.e., less
avoidance behavior with closer interaction). Based on our findings, we have the following recommendations: (a) limit vessels
from approaching mothers with calves, (b) limit vessels from approaching small groups of cetaceans, (c) reduced avoidance
behavior to boat traffic may be a red flag for potential long-term disturbance, and (d) apply the “precautionary principle”
based on the best scientific information available in cetacean-based tourism in Taiwan. These recommendations will help contribute
to the sustainable development of cetacean-focused tourism in Taiwan. 相似文献
