Research into the origins of strong arsenic anomalies in southwest Tuscany helped in realising the correlation between ancient mining activities and higher levels of the element. Besides an indication about the source of arsenic pollution in this area, these results indicate that arsenic can be used to trace major archaeoindustrial settlements. This research can provide precious information about the medieval period, when land use and ore extraction were regulated, for the first time, by a mining code. Interesting data can also be obtained about the Etruscan population and their ability to extract and work various metals, which confirmed their predominance in central Italy in the pre-Roman period. This kind of study could also be extended to other substances.","PeriodicalId":13902,"journal":{"name":"International Journal of Design & Nature and Ecodynamics","volume":"22 1","pages":"24-26"},"PeriodicalIF":0.0,"publicationDate":"2007-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87740376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, there are costs of management activities such as hazard reduction, eradication and control. The assessment of these costs and the determination of the optimal management response have attracted attention in recent years. Minimising the expected present value of the total of the above mentioned costs is one of the criteria for determining how to protect the economy from the effects of unmitigated hazards. It involves a tradeoff between additional expenditure on management activities such as hazard reduction and their expected benefits such as a reduced hazard rate of future incursions. In this paper, an analytical expression is developed for the expected discounted present value of all future incursion and management costs for the case of recurrent episodes of pest or disease incursion and eradication, where there is uncertainty about the arrival of disease incursions and about the outcome of the eradication process. Uncertainty about the outcome of the eradication process means that it is uncertain whether the pest or disease is completely removed at the end of the eradication process. The optimal expenditure on management activities for a risk neutral decision maker is obtained by minimising the derived expression with respect to the levels of management activities, subject to the relationships between management activities and their associated outcomes such as a reduction of the hazard rate. An example is provided to illustrate the determination of the combination of management activities that minimises the expected economic cost of pest or disease incursions.","PeriodicalId":13902,"journal":{"name":"International Journal of Design & Nature and Ecodynamics","volume":"198 1","pages":"348-360"},"PeriodicalIF":0.0,"publicationDate":"2007-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78126485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The character of earth history 地球历史的特征

Some of the fundamental processes that regulate the evolution of the earth display a repetitive, cyclical behavior, whereas others are characterized by irreversible, unidirectional trends. Both processes, i.e. cycles and trends, may be seen as long-term patterns in earth history. These patterns may coexist, and may be modulated by occasional, but extremely important, chance events. It has been suggested that the interplay between chance events and long-term patterns is a feature in human history; in this paper we propose that the same character applies to earth history as well. This suggestion is illustrated with geological examples: we discuss the tectonic evolution of mountain belts that display components of both cyclical and unidirectional trends. We then provide an example of a dramatic, important chance event, namely the impact of a large meteorite on the earth’s surface that caused the Cretaceous–Tertiary boundary mass extinction 65 million years ago.","PeriodicalId":13902,"journal":{"name":"International Journal of Design & Nature and Ecodynamics","volume":"25 1","pages":"380-388"},"PeriodicalIF":0.0,"publicationDate":"2007-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75054453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research of such principles represents a fundamental step toward a keener understanding of the functioning of the real world and is a prerequisite for the sustainable management of natural resources. The lagoon of Venice is the largest in the Mediterranean Sea, and is an example of a complex transitional ecosystem subjected to strong anthropogenic influences. It has been studied by both local and international scientific communities. Only recently, however, have systematic, basin-wide, monitoring and research efforts been taking place. Here we show that differences in meteorological conditions cause substantial interannual variability in the water quality parameters of the lagoon of Venice. Indeed, even thoughnutrientloadsoriginatinginthedrainagebasinare,onanannualbasis,roughlyconstant,ananalysisofthe time evolution of the spatial distributions of the concentration of nutrients and chlorophyll a reveals remarkable interannual differences, superimposed on a well recognizable seasonal pattern. These differences are related to the amount of rain in spring and summer. In all the three years analyzed, a clear spatial structure is present. The existence of a strong correlation of distribution of trophic variables with salinity and residence times indicates that the lagoon can be described almost in toto by the balance achieved by its freshwater input, tidal flushing, and the annual cycle of solar radiance.","PeriodicalId":13902,"journal":{"name":"International Journal of Design & Nature and Ecodynamics","volume":"163 1","pages":"339-347"},"PeriodicalIF":0.0,"publicationDate":"2007-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86412401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
