一种利用公式和SQL语句将Excel数据升迁至关系型数据库的方法

本文讨论了一种利用Excel的公式和Sql语句来完成Excel数据导入到关系型数据库的方法。某些Excel数据具备一定的特征，但又不像关系型数据库那样每行对应着一条记录，而是一块数据对应着一条记录，对于这种情况，本文首先利用IF函数判断某个单元格是否需要生成Sql语句，如果需要生成Sql语句，再利用CONCATENATE函数把单元格的内容放到一条InsertSql中去。最后利用把Sql语句拷贝到一个文本文件中去。

CO2-emissions from agriculture: Sources and mitigation potentials

In 1991/92, the subgroup “Agriculture and Forestry” of the IPCC Working Group III developed an update of its earlier statements in the first IPCC-Report, concerning the release of greenhouse gases from agriculture. The present paper is an extract from this updated IPCC Supplement, concentrating on the CO₂ emissions from agriculture and its potentials for mitigation.     

Statistical methods helping and hindering environmental science and management

Environmental scientists face the reality that many of their journals’ editors and referees routinely insist that results be accompanied by statements of statistical significance, obtained from two-sided tests of point-null hypotheses. Many in these three groups of people appear only vaguely a ware of the arbitrarinessoften invoked by this procedure and of the information sterility in a single p-value. The interpretation to be made of the failure of a test to attain such significance is not clear. For such reasons, some colleagues (and senior statisticans) have called current usage of the procedures into serious question. Some reasons for this dislocation and some of the more dramatic consequences for environmental science and management are presented. Interval and Bayesian approaches can offer remedies.     

Exotic fishes in fresh and brackish waters of Florida

At least 38 species and several hybrids of exotic fishes have been found in fresh and brackish waters of Florida. Twenty species and five hybrids are at present established in the form of reproducing populations. The ornamental aquarium fish industry has been the major source of these introductions. Several methods of introductions are considered and recommendations presented toward preventing repetitions in the future. Future dispersal of exotics by channelization projects should become part of environmental impact statements.     

Perspectives on soil fertility change: a case study from southern Ethiopia

This paper explores the complexities underlying the apparently simple question—Is soil fertility declining?—for Wolayta in southern Ethiopia, an area famed for its high population densities and extreme pressure on resources. Drawing on extensive field research in the area, the paper examines differing perceptions of soil fertility decline, and attempts to pick apart the range of evidence of changes in soil fertility over time from a variety of different sources, ranging from historical interviews with farmers to fertilizer trials carried out over many years. In contrast to the definitive statements so often made in development policy statements, the actual situation is much less clear. A detailed understanding of soil fertility dynamics is only reached by a farm and field level examination of soil nutrient balances. Differences according to agroecological zone and socio-economic group are evaluated. These results show that soil fertility is indeed declining in some places, for some people and over certain periods, but it is not universal. Indeed, soil fertility is apparently increasing at certain sites. The implications of such findings for development policy and practice are briefly explored.

“Preferential flow”: Eine Übersicht über den heutigen Kenntnisstand

Preferential flow: A review of current knowledge Despite intensive research neither suitable methods of measurement, nor complete theoretical statements give an adequate account of preferential flow due to the exceptional complexity and variability of the soil system. In particular it is not possible to make predictions of preferential flow for a given soil due to observations and measurements. In this work we describe theoretical and technical problems of preferential flow and initiate ideas for future work in this field.     

Bioindication of radioactive contamination of natural ecosystems

This article is based on materials of original complex dynamic surveys carried out during 1986–2012 in natural ecosystems of the Russian Federation and Ukraine that were contaminated due to the Chernobyl disaster. A number of statements were formulated regarding the bioindication of basic components of the ecosystem (arboreal and herbaceous vegetation, mosses, lichens, and higher fungi), and some temporal changes were shown in ranks of the bioindicators.     

High level of mislabeling in Spanish and Greek hake markets suggests the fraudulent introduction of African species

DNA analysis of hake products commercialized in southern European (Spanish and Greek) market chains have demonstrated more than 30% mislabeling, on the basis of species substitution. Tails and fillets were more mislabeled than other products, such as slices and whole pieces. African species were substitute species for products labeled as American and European species, and we suggest it is a case of deliberate economically profitable mislabeling because real market prices of European and American hake products are higher than those of African in Spanish market chains. The presented results suggest fraud detection that disadvantages African producers. Government-mandated genetic surveys of commercial hakes and the use of subsequent statements of fair trade on labels of seafood products could help to reduce fraud levels in a global market of increasingly conscious consumers sensitive to ethical issues.     

Effect of Information Communication Technology on Agricultural Information Access Among Researchers,Extension Agents,and Farmers in South Western Nigeria

This study compared researchers, extension agents, and farmers’ perceptions of the effect of Information Communication Technology (ICT) on agricultural information access. A simple random sampling technique was used to select 88 researchers, 115 extension agents, and 271 farmers. Data collected through a structured questionnaire were analyzed using means, standard deviation, and one-way analysis of variance. The results showed that, of the 29 statements on the rating scale, researchers, extension agents, and farmers agreed with and were positively disposed to 25, 23, and 19, respectively. A significant difference in the effect of ICT on agricultural information access among researchers, extension agents, and farmers (F = 6.49, p < .05) was observed. Access to agricultural information through ICT will continue to improve, since perceptions are overtly positive among researchers, extension agents, and farmers.
