This article explores the possibility of a “partnership‐with‐nature” frame as experienced through interactions with urban “green” buildings. The discussion is situated in the broader context of an emerging green building movement and the cultural role played by the Leadership in Energy and Environmental Design certification framework and its supporting networks. Examples are drawn from an ethnographic case study of a particular green building, the Heifer International headquarters in Little Rock. More broadly, the article reflects on how nature and culture are coming together in new ways in our real and imagined urban spaces.  相似文献

Recreational fishing is a very popular outdoor leisure activity. Assessing differences in basic metrics in recreational fishing on different types of fishing grounds is very important for effective fisheries management. This study aimed to discover how basic metrics in recreational fishing (harvest, fishing effort, angling guard activities) differ between urban fishing grounds (located in a densely populated city) and natural fishing grounds (located in the countryside). Data were obtained from individual angling logbooks collected by the Czech Fishing Union on the River Elbe and the River Vltava (Prague and Central Bohemia, Czechia, Central Europe). Study shows that urban and natural fishing grounds showed significant differences in basic metrics in recreational fishing. Urban fishing grounds displayed higher fish harvest in general and higher dominance of intensively stocked fish species in catches of anglers (mainly common carp Cyprinus carpio). High harvest rates of common carp can be mostly explained by intensive fish stocking. The only fish species that showed higher harvest on natural fishing grounds were large-growing piscivorous fish with high ecological demands. However, anglers were harvesting larger fish (average body weight) on natural fishing grounds. In addition, fishing effort was similar on both types of fishing grounds. Inversely, angling guards were more active on natural fishing grounds. In conclusion, differences in basic fisheries metrics between urban and natural fishing grounds seem to be partially driven by intensive fish stocking.

Abstract

The objective of the study was to identify the differences in 24-h variations in moods between three groups of oil-refinery workers: tolerant shiftworkers, intolerant shiftworkers and workers who had never worked in shifts. Each group comprised 29 workers matched by age. The mood measurements were taken during a 24-h period every 2 h starting from 08:00 h. Results were scored for three scales: positive moods, negative moods and fatigue. The two-factor ANOVA revealed the significant main effect of groups for all three moods indicating differences at the average level of 24-h variations in all moods between workers who differed in the degree of tolerance to shiftwork. The significant main effect of time of day was also found for all moods while the reliable interaction between groups and time of day was observed for negative moods only, indicating a different shape of 24-h variations for non-shiftworkers in comparison to shiftworkers.  相似文献

We analysed the relation between foreign direct investment and the quality of the institutional environment in transition economies. The analysis confirmed a significant impact of various institutional aspects on the inflow of foreign capital. To isolate the importance of the institutional environment from the impact of other factors, a panel data analysis was performed using the data of 24 transition economies in the period 1995–2002. The results showed that in the observed period the quality of the institutional environment significantly influenced the level of foreign direct investment in transition economies. Other variables that proved to have a statistically significant influence were budget deficit, insider privatization, and labour cost per hour.  相似文献

The article discusses the results of sociological research on environmental awareness in Croatia. A strong anti‐nuclear attitude is present, especially with respect to radioactive waste. Education is by far the strongest determining variable: those of high educational qualifications are critical in general as well as vis‐à‐vis specific issues, yet not necessarily critical in a negative sense.  相似文献
