CHILDREN'S PERCEPTION OF A DOWNTOWN SHOPPING CENTER     

Geoffrey C. Smith  Denis J. B. Shaw  Peter R. Huckle 《The Professional geographer》1979,31(2):157-164

This paper offers an exploratory investigation of the effects of a child's age on three behavioral constructs (awareness space, activity space, and attitude) concerning a downtown shopping center in Bristol, England. The data are elicited from three samples of Bristol school children defined according to age and are analyzed using statistical inferential procedures. The results disclose that awareness space and activity space consistently increase with age. In addition, attitudinal responses to specific features of the shopping center exhibit a gradual change over a long-term period.  相似文献

Climatic deterioration and the end of the Gortian Interglacial in sediments from Derrynadivva and Burren Townland,near Castlebar,County Mayo,Ireland     

Peter Coxon  Gina Hannon  Peter Foss 《第四纪科学杂志》1994,9(1):33-46

Pollen and macrofossil analyses of two sequences of organic sediment in western Ireland have allowed the recognition of the latter parts of the Gortian Interglacial, a Middle Pleistocene temperate stage. The palaeobotanical information from the two sites identifies the preservation of partial sequences from the Gortian Interglacial (believed to be the equivalent of the Hoxnian Stage of Britain and the Holsteinian of Europe). The pollen and macrofossil data from one of the sites, Derrynadivva, span the middle and latter parts of the temperate stage. The results show that fire influenced the vegetation throughout the middle part of the temperate stage, and the termination of the organic depositional sequence appears to have been due to environmental deterioration. The former is identified through the abundant occurrence of charcoal in the sediments, whereas the latter is apparent in the sediment sequence and in the reworking of thermophilous pollen types into the upper part of the deposit. The second site, Burren Townland, records only part of the later zones of the interglacial, but the ericaceous assemblages of the latter part of the Gortian Interglacial are well developed and well preserved. Macrofossil analyses and scanning electron microscopy work on the pollen at the latter site has allowed the recognition of Rhododendron ponticum, adding to previous records of this species, which now has a very disjunct European distribution.  相似文献

Mercos — A simple Teflon sampler for ultratrace metal analysis in seawater     

Peter Freimann  Diether Schmidt  Karl Schomaker 《Marine Chemistry》1983,14(1):43-48

This paper describes an uncomplicated sampling technique for ultratrace element analysis of coastal and surface seawaters (maximum depth 100 m). The sampler system is very easy to operate. To prevent contamination problems, interchangeable 500-ml Teflon bottles are used as both sampling and storage vessels. The seawater samples are stabilized in situ by preacidifying the sampling bottles. For the determination of mercury in seawater the desired system has been developed: sampling bottle = storage bottle = reaction vessel.  相似文献   

Water resource management in the USA: a case study of large dams     

Peter Beaumont 《Applied geography (Sevenoaks, England)》1983,3(4):259-275

The construction of large dams in the USA reveals a rapid growth in activity in the post-Second World War period, with the largest number of dams being inaugurated in the mid-1960s. Texas, with 823 dams, is the state with the largest number, followed in turn by California, Oklahoma, Pennsylvania and Colorado. At the other extreme some states have fewer than a dozen dams. Although there are large variations in the number of dams between states nearly all of them record peak constructional activity between the late 1950s and early 1970s. Surprisingly, most dams have relatively small reservoirs with about 70 per cent of the total having capacities of less than 10⁶ m³. Over two-thirds of all dams have been constructed with a single aim in view, with flood control being the most important reason. Only 1.5 per cent of all dams are utilized for four or more purposes. The objectives behind dam construction reveal changes since the 19th century. In the early years of the 20th century irrigation, hydro-electric power generation and water supply were the most important reasons for dam construction, whereas in the post-1950 period flood control stands out as the dominant activity. Changing technology, the introduction of specific legislation and changing attitudes to the environment have been the major influences on dam-building activity over the period studied.  相似文献
