Factors influencing households' participation in recycling 总被引:2,自引:0,他引:2
The success of a recycling programme depends on the active and sustained participation of citizens in the correct separation and collection of recyclable waste. An effective study of strategies aimed at augmenting people's involvement in recycling involves understanding which factors influence the decision to co-operate with a recycling programme. This research investigates the influence of attitudes, incentives, presence of children in household and information through direct media, on households' participation in recycling. The results suggest that positive attitudes toward recycling and information are important factors in explaining recycling participation. Some guidelines that may be considered in future communication and intervention strategies designed to promote recycling participation are discussed. 相似文献

Watershed management program on Santiago Island,Cape Verde 总被引:1,自引:0,他引:1
The Watershed Management Program (WMP) was put into operation in early 1985 on Santiago Island, Cape Verde, with the stated
purpose, “to develop and protect the soil and water resources of the Program-designated watersheds … to stabilize the natural
environment and increase agricultural production potential in the Program area.” The approach to soil and water conservation
in the program has been to build erosion and flood control structures (engineering approach) and plant trees (biological approach)
to decrease rill and gully erosion, trap sediment behind control structures, provide flood protection, increase infiltration,
increase fuelwood and fodder production, and increase water supplies for irrigation. There have been many successes resulting
from specific management activities, but flawed approach or implementation in a few key areas has acted to impede the program's
complete success, including lack of a scientific basis for evaluating its impact on soil and water conservation; poor design,
placement, and maintenance of some major hydraulic structures; inadequate intervention in stabilizing farmlands or education
of farmers and landowners in the need for and benefits of agroforestry; and incomplete integration of engineering and biological
approaches. 相似文献

Variations in the gene encoding the low-density lipoprotein receptor (LDLR) can cause familial hypercholesterolemia (FH), one of the most common inherited metabolic disorders in humans. The functional
effects of the p.Gln92Glu and p.Asn564His alterations are predicted as benign, but the c.313 + 1G>C and p.Lys799_Phe801del
changes are believed to cause disease. Although p.Gln92Glu and c.313 + 1G>C have been observed only in Spain, p.Asn564His
and p.Lys799_Phe801del are widespread in Western Europe. In order to estimate the ages (t generations) of these four variants of the gene, to determine their possible origin and to consider the influence of age
and selective pressure on their spread, we analyzed 86 healthy individuals and 126 FH patients in Spain. Most of the FH patients
investigated carried two of these four LDLR variants simultaneously, while only one patient carried three of them simultaneously. Haplotype analyses were based on five
LDLR SNPs: c.81T>C, c.1413G>A, c.1725C>T, c.1959T>C and c.2232G>A. The results suggest that p.Gln92Glu and c.313 + 1G>C arose
at about the same time (99 and 103 generations ago, respectively) in the CACTG haplotype and that p.Asn564His and p.Lys799_Phe801del
appeared in the CGCCG haplotype and might be slightly more recent variations (92 and 95 generations ago, respectively). Low
selective pressures could explain the maintenance of these variants in spite of their ages. The origin of p.Gln92Glu and c.313 + 1G>C
appears to be in Spain whereas p.Asn564His and p.Lys799_Phe801del could have been introduced in Spain by Celtic migrations
in the seventh to fifth centuries BC. 相似文献

Electron transport system (ETS) activity of sediments as an indication of microbial metabolic activity was examined in two
adjacent Mediterranean wetlands (southern Spain). We determined the spatio-temporal variation in ETS, and we explored the
potential biological [organic matter (OM), chlorophyll a (Chl a), aerobic and anaerobic bacteria] drivers of sediment ETS
activity. ETS activity was notably higher in the eutrophic Lake Nueva (34.91 μl O2 g−1 D.W. h−1) than in the hypertrophic Lake Honda (24.99 μl O2 g−1 D.W. h−1). Strong spatial differences were observed in ETS in both study sites. Highest ETS values were achieved at the surface sediment
at the deepest sampling station in each lake and a notable reduction in ETS with sediment depth was observed. By using linear
regression and multiple regression analysis, OM was identified as the best predictor of ETS in Lake Honda while Chl a was
the best predictor in Lake Nueva. The strong influence of OM supply on ETS activity in sediment from Lake Honda was the consequence
of the labile nature of sedimentary OM, while a more refractory OM (with a higher contribution of vascular plants) comprised
most of the sedimentary OM from Lake Nueva. By contrast, a large contribution of phytobenthos (supported by a higher lake
water transparency) to ETS has been recognized in sediments from Lake Nueva. In summary, the results of this study revealed
that the relative importance of planktonic primary producers (phytoplankton), benthic algae and vascular plants in the study
sites could explain the differences observed in the intensity of sediment ETS as well as in their drivers. 相似文献
