The politics of contaminated sites management : institutional regime change and actor's mode of participation in the environmental management of the Bonfol Chemical Waste Landfill in Switzerland

By the end of the 1970s, contaminated sites had emerged as one of the most complex and urgent environmental issues affecting industrialized countries. The authors show that small and prosperous Switzerland is no exception to the pervasive problem of sites contamination, the legacy of past practices in waste management having left some 38,000 contaminated sites throughout the country. This book outlines the problem, offering evidence that open and polycentric environmental decision-making that includes civil society actors is valuable. They propose an understanding of environmental management of contaminated sites as a political process in which institutions frame interactions between strategic actors pursuing sometimes conflicting interests. In the opening chapter, the authors describe the influences of politics and the power relationships between actors involved in decision-making in contaminated sites management, which they term a "wicked problem." Chapter Two offers a theoretical framework for understanding institutions and the environmental management of contaminated sites. The next five chapters present a detailed case study on environmental management and contaminated sites in Switzerland, focused on the Bonfol Chemical Landfill. The study and analysis covers the establishment of the landfill under the first generation of environmental regulations, its closure and early remediation efforts, and the gambling on the remediation objectives, methods and funding in the first decade of the 21st Century. The concluding chapter discusses the question of whether the strength of environmental regulations, and the type of interactions between public, private, and civil society actors can explain the environmental choices in contaminated sites management. Drawing lessons from research, the authors debate the value of institutional flexibility for dealing with environmental issues such as contaminated sites.

Iowa Department of Transportation Fiscal Year 2006 Report of Savings by Using Video Conferencing Through Iowa Communications Network, January 2007

Pursuant to Chapter II 84 Acts and Joint Resolutions enacted at the 1994 Regular Session of the 75th General Assembly of the State of Iowa - Code section 8D.10 Report of Savings by State Agencies Iowa Code section 8D.10 requires that certain state agencies prepare an annual report to the General Assembly certifying the identified savings associated with that state agency’s use of the Iowa Communications Network (ICN). This report covers estimated cost savings related to video conferencing via ICN for the Iowa Department of Transportation (DOT). In FY 2006, the DOT conducted two sessions utilizing ICN’s video conferencing system which resulted in $13,017 in estimated savings to the DOT.

Érosion des sols au Cap Vert : étude des processus et quantification à l’échelle de trois bassins versants de l’île de Santiago

Erosão dos solos em Cabo Verde: estudo dos processos e quantificação à escala de três bacias hidrográficas O arquipélago de Cabo Verde é constituído por 10 ilhas vulcânicas pertence à zona do Sahel que se estende do Atlântico ao Mar Vermelho. Desde então, várias décadas, Cabo Verde é afectado pela desertificação causada principalmente pela recessão climatica e a erosão do solo. Esses fatores, aliados à alta pressão humana sobre os recursos, a topografia acidentada e chuvas tropicais por vezes torrenciais, causam sérios danos aos solos. No entanto, desde sua independência em 1975, o Governo realizou um amplo programa de arborização, recuperação de áreas degradadas e a correcção dos leitos das ribeiras. No entanto, a investigação, muito pouco foi realizada para avaliar as acções de protecção e conservação do solo e da água. Portanto, não há dados sobre o problema da degradação das terras nem balanços. Como parte deste trabalho, foram estudados vários factores que controlam a erosão do solo pela água. Especificamente, buscou-se diferenciar os efeitos das actividades humanas, incluindo a agricultura, os factores climáticos, como chuva e geração de escoamento. Também estabeleceu os primeiros balanços das exportações de matérias em suspensão e em solução no contexto do arquipélago de Cabo Verde. O estudo foi realizado em três bacias hidrográficas da ilha de Santiago, Cabo Verde. Estas três bacias hidrográficas (Longueira, Grande e Godim) estão localizadas na parte central da ilha de Santiago e representam os diversos tipos de uso da terra e as diferentes zonas bioclimaticas da ilha. Existe um gradiente climático entre as três bacias hidrográficas. Na verdade, Longueira que abrange uma área de 4,18 km2, tem um declive médio de 47 %, uma zona florestada de 69% e uma área agrícola de 17 %. Grande com uma área de 1,87 km2, é localizada numa zona sub humida com um declive médio de 50%, é essencialmente agrícola. Godim, com uma área de 2,0 km2, é localizado numa zona semi-árida com um declive médio de 32%, é particularmente uma zona agricola. Para estes três bacias hidrográficas, as cheias foram medidas e amostradas de 2004 a 2009. A bacia de Longueira teve um maior acompanhamento, nomeadamente em termos de amostragem e monitoramento dos escoamentos. Em cada amostra foram feitas a determinação da concentração de matérias em suspensão e a análise dos principais elementos quimicos. Os resultados mostram que a erosão mecânica nas três bacias hidrográficas é caracterizada por uma forte variabilidade espacial e temporal. Durante o período de 2005-2009, o balanço anual média para as bacias hidrográficas de Longueira, Grande e Godim é: 4266, 157 e 10,1 t.km2.an-1, respectivamente. A estação das chuvas de 2006 foi a mais erosiva para as três bacias, particularmente em Longueira, com 2 cheias excepcionais, que têm gerado uma concentração média de sólidos em suspensão superior a 100 g / l. Porém, as estações do ano de 2005 e 2008 foram de uma forma geral menos erosivas porque as concentrações médias não inferiores a 20 g / l. Além disso, não houve cheias para as temporadas 2005 e 2007 para a bacia do Godim. Na bacia de Longueira, o estudo dos fenómenos de histerese na caracterização das cheias mostrou que a evolução temporal das exportações de sólidos em suspensão durante a temporada é fortemente influenciada pelas atividades agrícolas. Na verdade, a primeira cheia causou uma exportação maciça de sedimento disponível e localizado no leito da ribeira. Assim, a segunda cheia exportou menos sedimentos. Um mês após as primeiras chuvas, a prática da monda que reduz a densidade da cobertura vegetal e destructura a camada superficial do solo, gerou uma grande quantidade de sedimento que novamente permitiu uma exportação muito forte de sedimentos durante a terceira forte cheia. Os resultados da erosão química na bacia de Longueira indicam que a taxa de erosão é de 45 t.km2.an-1 com uma forte variabilidade temporal. Na verdade, as temporadas de 2006 e 2007 são as mais erosivas, enquanto 2005 teve uma exportação de matérias disolvidas baixa. A utilização do modelo EMMA (End- Members Mixing Analysis) mostra que os escoamentos hipodermico e profundo, alimentandos os fluxos de elementos dissolvidos são os principais factores da erosão química. É mostrado que esses fluxos causam mais de 90% dos fluxos de erosão química. O escoamento superficial, que contribui com cerca de 70% na formação das cheias, é o maior factor da erosão mecânica do solo.

Determinants of linear judgment: A meta-analysis of lens model studies

The mathematical representation of Brunswik s lens model has been usedextensively to study human judgment and provides a unique opportunity to conduct ameta-analysis of studies that covers roughly five decades. Specifically, we analyzestatistics of the lens model equation (Tucker, 1964) associated with 259 different taskenvironments obtained from 78 papers. In short, we find on average fairly high levelsof judgmental achievement and note that people can achieve similar levels of cognitiveperformance in both noisy and predictable environments. Although overall performancevaries little between laboratory and field studies, both differ in terms of components ofperformance and types of environments (numbers of cues and redundancy). An analysisof learning studies reveals that the most effective form of feedback is information aboutthe task. We also analyze empirically when bootstrapping is more likely to occur. Weconclude by indicating shortcomings of the kinds of studies conducted to date, limitationsin the lens model methodology, and possibilities for future research.

Bands width, credibility and exchange risk: Lessons from the EMS experience

This paper presents an analysis of the credibility of the EMScurrencies that covers the period before and after the increase in thebands of fluctuation. Our credibility indicator is based on the inferredprobabilities derived from the estimation of a Markov-switching model(Hamilton (1989)) applied to the expected rate of depreciation. Theresults show that, for most of the currencies, credibility has improved,at least transitorily, after the increase in the bands. However, for allcurrencies, the credibility measured by the indicator proposed in thispaper has been eroded recently even with the widened bands.

Report of Savings by Using Video Conferencing Through Iowa Communications Network

Iowa Department of Transportation Fiscal Year 2007 Report of Savings by Using Video Conferencing Through Iowa Communications Network to the Iowa General Assembly Pursuant to Chapter II 84 Acts and Joint Resolutions Enacted at the 1994 Regular Session of the 75th General Assembly of the State of Iowa Code section 8D.10 Report of Savings by State Agencies Iowa Code section 8D.10 requires certain state agencies prepare an annual report to the General Assembly certifying the identified savings associated with that state agency’s use of the Iowa Communications Network (ICN). This report covers estimated cost savings related to video conferencing via ICN for the Iowa Department of Transportation (DOT). In FY 2007, the DOT conducted two sessions utilizing ICN’s video conferencing system. These two sessions included DOT employees in Ames with non-DOT participants at remote ICN sites. Since the cost savings is calculated based on DOT staff savings, no cost savings from these conferences were gained because the public participants were attending from the ICN sites.

Calceology : an introduction to North Western European archaeological leather footwear (Neolithic period to c. AD 1600)

Calceology is the study of recovered archaeological leather footwear and is comprised of conservation, documentation and identification of leather shoe components and shoe styles. Recovered leather shoes are complex artefacts that present technical, stylistic and personal information about the culture and people that used them. The current method in calceological research for typology and chronology is by comparison with parallel examples, though its use poses problems by an absence of basic definitions and the lack of a taxonomic hierarchy. The research findings of the primary cutting patterns, used for making all leather footwear, are integrated with the named style method and the Goubitz notation, resulting in a combined methodology as a basis for typological organisation for recovered footwear and a chronology for named shoe styles. The history of calceological research is examined in chapter two and is accompanied by a review of methodological problems as seen in the literature. Through the examination of various documentation and research techniques used during the history of calceological studies, the reasons why a standard typology and methodology failed to develop are investigated. The variety and continual invention of a new research method for each publication of a recovered leather assemblage hindered the development of a single standard methodology. Chapter three covers the initial research with the database through which the primary cutting patterns were identified and the named styles were defined. The chronological span of each named style was established through iterative cross-site sedation and named style comparisons. The technical interpretation of the primary cutting patterns' consistent use is due to constraints imposed by the leather and the forms needed to cover the foot. Basic parts of the shoe patterns and the foot are defined, plus terms provided for identifying the key points for pattern making. Chapter four presents the seventeen primary cutting patterns and their sub-types, these are divided into three main groups: six integral soled patterns, four hybrid soled patterns and seven separately soled patterns. Descriptions of the letter codes, pattern layout, construction principle, closing seam placement and list of sub-types are included in the descriptions of each primary cutting pattern. The named shoe styles and their relative chronology are presented in chapter five. Nomenclature for the named styles is based on the find location of the first published example plus the primary cutting pattern code letter. The named styles are presented in chronological order from Prehistory through to the late 16th century. Short descriptions of the named styles are given and illustrated with examples of recovered archaeological leather footwear, reconstructions of archaeological shoes and iconographical sources. Chapter six presents documentation of recovered archaeological leather using the Goubitz notation, an inventory and description of style elements and fastening methods used for defining named shoe styles, technical information about sole/upper constructions and the consequences created by the use of lasts and sewing forms for style identification and fastening placement in relation to the instep point. The chapter concludes with further technical information about the implications for researchers about shoemaking, pattern making and reconstructive archaeology. The conclusion restates the original research question of why a group of primary cutting patterns appear to have been used consistently throughout the European archaeological record. The quantitative and qualitative results from the database show the use of these patterns but it is the properties of the leather that imposes the use of the primary cutting patterns. The combined methodology of primary pattern identification, named style and artefact registration provides a framework for calceological research.

Active civic participation of immigrants in Portugal

Portugal’s historical past strongly influences the composition of the country’s immigrant population. The main third-country foreign nationals in Portugal originate traditionally from Portuguese-speaking African countries (namely Cape Verde, Angola, Guinea Bissau, and S. Tomé e Príncipe) and Brazil. In 2001, a newly created immigrant status entitled “permanence” authorization uncovered a quantitative and a qualitative change in the structure of immigrant population in Portugal. First, there was a quantitative jump from 223.602 foreigners in 2001 to 364.203 regularized foreigners in 2003. Secondly, there was a substantial qualitative shift in the composition of immigrants. The majority of the new immigrants began coming from Eastern European countries, such as Ukraine, Moldavia, Romania, and the Russian Federation. Thus, European countries outside the E.U. zone now rank second (after African countries) in their contribution of individuals to the stocks of immigrant population in Portugal. The differences between the new and traditional immigration flows are visible in the geographical distribution of immigrants and in their insertion into the labour market. While the traditional flows would congregate around the metropolitan area of Lisbon and in the Algarve, the new migratory flows tend to be more geographically dispersed and present in less urbanized areas of Portugal. In terms of insertion in the labour market, although the construction sector is still the most important industry for immigrant labour, Eastern European workers may also be found in the agriculture and manufacturing sectors. The institutional conditions that encourage immigrants’ civic participation are divided at three different levels: the state, the local, and the civil society levels. At the state level, the High Commissioner for Migrations and Ethnic Minorities is the main organizational structure along with a set of interrelated initiatives operating under specific regulatory frameworks, which act as mediators between state officials and the Portuguese civil society, and more specifically, immigrant communities. At the local level, some municipalities created consultative councils and municipal departments aiming at encouraging the participation and representation of interests from immigrant groups and association in local policies. In the civil society sphere, the main actors in Portugal spurring immigrants civic participation are immigrant associations, mainstream associations directed toward immigration topics, and unions. The legal conditions framing immigrants’ access to social housing, education, health, and social security in Portugal are also considered to be positive. Conditions restricting immigrants’ civic participation are mainly normative and include the Portuguese nationality law, the regulations shaping the political participation of immigrants, namely in what concerns their right to vote, and employment regulations restricting immigrants’ access to public administration positions. Part II of the report focuses on the active civic participation of third country immigrants. First, reasons for the lack of research on this issue in Portugal are explained. On the one hand, the recent immigration history and the more urgent needs regarding school and economic integration kept this issue out of the research spotlight. On the other hand, it was just in the beginning of the 1990s that immigrants took the very first steps toward collective mobilisation. Secondly, the literature review of Portuguese bibliography covers research on third country immigrants’ associative movement, research on local authorities’ policies and discussion about ethnic politics and political mobilisation of immigrants in Portugal. As political mobilisation of these groups has been made mainly through ethnic and/or migrant organisations, a brief history of immigrants' associative movement is given. Immigrant associations develop multiple roles, covering the social, the cultural, the economic and the political domains. Political claiming for the regularisation of illegal immigrants has been a permanent and important field of intervention since the mid-1990s. Research results reveal the com5 plex relations between ethnic mobilisation and the set of legal and institutional frameworks developed by local and national governmental authorities targeted to the incorporation of minority groups. Case studies on the Oeiras district and on the Amadora district are then presented. Conclusions underline that the most active immigrant groups are those from Cape Verde and Guinea Bissau, since these groups have constituted a higher number of ethnic associations, give priority to political claiming and present a more politicised discourse. Reflecting on the future of research on civic participation of third country immigrants in Portugal, the authors state that it would be interesting and relevant to compare the Portuguese situation with those of other European countries, with an older immigration history, and analyse how the Portuguese immigrants’ associative movement will be affected by a changing legal framework and the emergence of new opportunities within the set of structures regarding the political participation of minority groups.

A permeable cuticle in Arabidopsis leads to a strong resistance to Botrytis cinerea.

The plant cuticle composed of cutin, a lipid-derived polyester, and cuticular waxes covers the aerial portions of plants and constitutes a hydrophobic extracellular matrix layer that protects plants against environmental stresses. The botrytis-resistant 1 (bre1) mutant of Arabidopsis reveals that a permeable cuticle does not facilitate the entry of fungal pathogens in general, but surprisingly causes an arrest of invasion by Botrytis. BRE1 was identified to be long-chain acyl-CoA synthetase2 (LACS2) that has previously been shown to be involved in cuticle development and was here found to be essential for cutin biosynthesis. bre1/lacs2 has a five-fold reduction in dicarboxylic acids, the typical monomers of Arabidopsis cutin. Comparison of bre1/lacs2 with the mutants lacerata and hothead revealed that an increased permeability of the cuticle facilitates perception of putative elicitors in potato dextrose broth, leading to the presence of antifungal compound(s) at the surface of Arabidopsis plants that confer resistance to Botrytis and Sclerotinia. Arabidopsis plants with a permeable cuticle have thus an altered perception of their environment and change their physiology accordingly.

RAGBRAI Learn about the Land; Day 2, July 2008

On today’s ride we continue riding across the Southern Iowa Drift Plain. This landform region covers over 40% of the state and comprises most of southern Iowa. Over the last several million years Iowa was subjected to at least seven glacial advances. The last of these older advances occurred approximately 500,000 years ago. Since then the landscape has been subjected to stream erosion and from12,500-24,000 years ago was mantled with a thick blanket of loess before being further eroded.

Entrepreneurial structure of the mercantile company in pre-industrial Catalonia

The mercantile company was the basic form of enterprise in pre-industrial Catalonia. The aim of this paper is to study the formation and development of the mercantile companies in Barcelona whose end was the wholesale and retail sale of textiles in the botigues de teles (textile retail shops) throughout the eighteenth century. These firms were officially registered before a notary and their deeds reveal how these establishments were administered and managed.The study covers a sample of 121 mercantile companies, and the articles and documentation that were put into effect by 32 notaries who were active in Barcelona in the 18th century have been consulted in their entirety. From an initial selection of documentation, a total of 228 deeds registering companies have been found, 107 of which (47%) relate to the creation of companies whose various activities were centred in taverns, textile manufacturing, braiding.... While the 121 companies, which make up our sample and which account for 53% of the deeds registered with the notaries mentioned above, focused exclusively on the management of textile retail shops located in the commercial heart of the city. Thus one point of interest that the documentation reveals is that the majority of the mercantile companies registered by Barcelona notaries throughout the 18th century were establishments which traded in textiles. The first part of the article focuses on the structural characteristics of these enterprises, the number and socio-professional status of the partners and the extent of each partner s involvement in the administration and management. The second part of the article examines the capital investment made by each partner, their rights and obligations agreed on, the sharing out of profits and possible losses and the duration of the companies. The final aim of the paper is to highlight the evolution of these companies through one specific case.

The application of NMR and MS methods for detection of adulteration of wine, fruit juices, and olive oil. A review

This review covers two important techniques, high resolution nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS), used to characterize food products and detect possible adulteration of wine, fruit juices, and olive oil, all important products of the Mediterranean Basin. Emphasis is placed on the complementary use of SNIF-NMR (site-specific natural isotopic fractionation nuclear magnetic resonance) and IRMS (isotope-ratio mass spectrometry) in association with chemometric methods for detecting the adulteration.

Erosão dos solos em Cabo Verde - Estudos dos Processos e Quantificação de Três Bacias na Ilha de Santiago

L’archipel du Cap Vert constitué de 10 îles volcaniques appartient à la zone sahélienne qui s’étend de l’atlantique jusqu’à la mer rouge. Depuis, plusieurs décennies le Cap Vert est affecté par la désertification causée en grande partie par la récession climatique et l’érosion des sols. Ces facteurs, associés à la forte pression anthropique sur les ressources, à l’orographie accidentée et à des pluies tropicales parfois diluviennes, provoquent de sérieuses pertes du patrimoine foncier. Cependant, depuis son Indépendance en 1975, le Gouvernement a mené un vaste programme d’arborisation, de restauration des terres et d’aménagement des cours d’eau. Pourtant, très peu de recherches ont été menées pour évaluer les actions de protection et de conservation des sols et des eaux. Par conséquent, il n’existe quasiment pas de données sur la problématique de la dégradation des terres ni de bilans. Dans le cadre de ce travail, nous avons étudié les différents facteurs qui contrôlent l’érosion hydrique des sols. Nous avons plus particulièrement cherché à différencier les effets des activités humaines, notamment agricoles, de ceux des facteurs climatiques comme les précipitations et la génération des écoulements. Nous avons également établi les premiers bilans d’exportations de matières en suspension et en solution dans le contexte de l’archipel du Cap Vert. L’étude a été menée à l’échelle de trois bassins versants de l’ile de Santiago Cap-Vert. Ces trois bassins versant (Longueira, Grande et Godim) sont localisés dans la partie centrale de l’île de Santiago et représentatifs des divers modes d’occupation du sol et des différents climats de l’île. Il existe un gradient climatique entre les trois bassins versants. En effet, Longueira qui présente une superficie de 4,18 km2, une pente moyenne de 47 %, se localise dans une zone humide couverte à 69 % par une forêt et une surface agricole de 17 %. Grande avec une superficie de 1,87 km2, se localise en zone sub humide pour une pente moyenne de 50 %, il est essentiellement agricole. Godim, avec une superficie de 2,0 km2, se localise en zone semi aride, il est particulièrement agricole et sa pente moyenne est de 32 %. Pour ces trois bassins versants, les écoulements de crue à l’exutoire ont été mesurés et échantillonnés de 2004 à 2009. Le bassin versant de Longueira a fait l’objet d’un suivi plus poussé, notamment en termes de fréquence d’échantillonnage et de suivi des écoulements hors crue. Sur chaque échantillon nous avons procédé à la détermination de la concentration des matières en suspension ainsi qu’à l’analyse des éléments majeurs. Les résultats obtenus montrent que l’érosion mécanique dans les 3 bassins versants est caractérisée par une forte variabilité spatiale et temporelle. Sur la période 2005-2009, le bilan moyen annuel pour les bassins versants de Longueira, Grande et Godim est de : 4266, 157 et 10,1 t.km2.an-1 respectivement. La saison humide 2006 a été la plus érosive pour l’ensemble des trois bassins versants et particulièrement dans Longueira avec 2 crues exceptionnelles qui ont généré une concentration moyenne de matières en suspension supérieure à 100 g/l. En revanche, les saisons 2005 et 2008 ont été dans l’ensemble peu érosives car les concentrations moyennes ne dépassèrent pas 20 g/l. Par ailleurs, il n’y a pas eu de lames d’eau écoulées pour les saisons 2005 et 2007 pour le bassin de Godim. Sur le bassin de Longueira, l’étude des phénomènes d’hystérésis permet de caractériser chaque crue et de montrer que l’évolution temporelle des exportations de matières en suspension au cours de la saison est fortement influencée par les activités agricoles. En effet, la première crue provoque l’exportation massive des sédiments disponibles et localisés dans le lit du cours d’eau. En conséquence, la seconde est moins exportatrice de sédiments. Un mois après les premières pluies, les activités de sarclage diminuent la densité du couvert végétal et destructurent la partie superficielle des sols, ce qui provoque à nouveau une très forte exportation de sédiments lors de la troisième crue. Les résultats de l’érosion chimique sur le bassin de Longueira indiquent que le taux d’érosion chimique moyen s’élève à 45 t.km2.an-1 avec une forte variabilité temporelle. En effet, les saisons les plus humides de 2006 et 2007 sont les plus exportatrices de matières en solution, alors que 2005 a eu une faible exportation. L’utilisation du modèle de mélanges EMMA (End-Members Mixing Analysis) montre que les écoulements hypodermique et profond, qui alimentent le cours d’eau en éléments dissous, sont les principaux facteurs de l’érosion chimique. On montre ainsi que les écoulements hors crue sont à l’origine de plus de 90% des flux d’érosion chimique. L’écoulement superficiel, qui contribue à environ 70 % du débit du cours d’eau en crue, constitue un facteur de premier plan de l’érosion mécanique des sols.
