The challenge confronting those seeking to understand the institutional dimensions of global environmental change and patterns of land-use and land-cover change is to find effective methods for analyzing the dynamics of socio-ecological systems. Such systems exhibit a number of characteristics that pose problems for the most commonly used statistical techniques and may require additional and innovative analytic tools. This article explores options available to researchers working in this field and recommends a strategy for achieving scientific progress. Statistical procedures developed in other fields of study are often helpful in addressing challenges arising in research into global change. Accordingly, we start with an assessment of some of the enhanced...

An automated method for the assessment of mercury adsorption rates on particulate suspended matter OMA
Baeyens, W.F.J.; Decadt, G.; Dehairs, F.A.; Goeyens, L..
A continuous filtration system connected to a mercury auto-analyzer has been constructed for obtaining mercury adsorption rates on particulate suspended matter. The capabilities of this device have been demonstrated by carrying out a series of experiments under controlled physicochemical parameter conditions on samples of the Scheldt estuary. Duplicate measurements showed coefficients of variation ranging from 1 to 6 %. Depending on the physico-chemical conditions, the initial adsorption rate per unit of dissolved mercury concentration varied between 1.2 and 8.1 x 10<sup>-2</sup> mn<sup>-1</sup>.

An Integrated Approach to Analyzing (Adaptive) Comanagement Using the &#8220;Politicized&#8221; IAD Framework Ecology and Society
Whaley, Luke; Water Science Institute, Cranfield University; l.whaley@cranfield.ac.uk; Weatherhead, Edward K.; Water Science Institute, Cranfield University; k.weatherhead@cranfield.ac.uk.
Scholars of comanagement are faced with a difficult methodological challenge. As comanagement has evolved and diversified it has increasingly merged with the field of adaptive management and related concepts that derive from resilience thinking and complex adaptive systems theory. In addition to earlier considerations of power sharing, institution building, and trust, the adaptive turn in comanagement has brought attention to the process of social learning and a focus on concepts such as scale, self-organization, and system trajectory. At the same time, a number of scholars are calling for a more integrated approach to studying (adaptive) comanagement that is able to situate these normative concepts within a critical understanding of how context and power...

Appreciative Inquiry: An approach for learning and change based on our own best practices AgEcon
Acosta, Anne Starks; Douthwaite, Boru.
Since it was conceptualized in the late 1980s as a research methodology and change paradigm, the technique of ‘appreciative inquiry’ (AI) has proved to be highly effective for capturing the positive features of an organization or social system and energizing the members to strive for higher levels of performance. This Brief outlines the basic principles and methods of AI, describes various domains in which it has been undertaken and provides a recent example of its use in a centre affiliated with the Consultative Group on International Agricultural Research (CGIAR).

Bilan énergétique chez les mollusques bivalves : terminologie et méthodologie - Compte rendu du groupe de travail réuni au laboratoire national "Ecosystème conchylicole" de l'IFREMER La Tremblade (13 et 14 septembre 1984) ArchiMer
Heral, Maurice; Lucas, Albert; Deslous Paoli, Jean-marc; Goulletquer, Philippe; Masse, Henri; LABEIM (Laboratoire de Biologie et d'Ecologie des Invertébrés Marins).
En septembre 1984, MM. HERAL et DESLOUS-PAOLI organisèrent à La Tremblade, une "réunion méthodologie expérimentale mollusques". Cette rencontre faisait suite à un bref état qui s'était engagé au Congrès de Montpellier sur les "Bases biologiques de l'Aquaculture", où il était apparu que la terminologie et la méthodologie concernant le métabolisme des bivalves devaient être clarifiées. Grâce à une large information auprès des spécialistes français de la physiologie des bivalves, la réunion à La Tremblade a réuni un grand nombre de participants très motivés. Pendant 2 jours des discussions très animées ont permis de bien comprendre les échanges entre les bivalves et leur environnement et d'y jeter un regard neuf, ce qui impliquait une analyse critique du...

Bonamia sp. (Protozoa, Haplosporidia) parásito de Ostrea puelchana D’Orbigny, (Mollusca, Bivalvia) en el Golfo San Matías (Patagonia Argentina): Histopatología, identificación e infección OceanDocs
Kroeck, M.A..
Los moluscos bivalvos son organismos sedentarios que establecen una relación íntima no sólo entre ellos, sino también con el espacio que ocupan y con sus condiciones fisicoquímicas. Sus poblaciones pueden ser hospedadoras de múltiples organismos patógenos (virus,bacterias, hongos, protistas y metazoos), cuya presencia es regulada eficazmente a niveles infra, meta y suprapoblacionales en ambientes silvestres, no provocando, salvo excepcionalmente, impactos severos. Los cultivos a escala comercial producen concentraciones de individuos, con la consiguiente alteración del medio y del equilibrio natural en la relación parásito-hospedador, generándose condiciones apropiadas para el desarrollo de enfermedades. Entre los años 1995 y 1996 se instala, en la zona...

Can Qualitative and Quantitative Methods Serve Complementary Purposes for Policy Research?: Evidence from Accra AgEcon
Maxwell, Daniel G..
Qualitative and quantitative methods in social science research have long been separate spheres with little overlap. However, recent innovations have highlighted the complementarity of qualitative and quantitative approaches. The Accra Food and Nutrition Security Study was designed to incorporate the participation of a variety of constituencies in the research, and to rely on a variety of approaches—both qualitative and quantitative—to data collection and analysis. This paper reviews the way in which qualitative and quantitative methods were used in the Accra study. The argument of the paper is that the complementary use of qualitative and quantitative approaches provides a greater range of insights and perspectives and permits triangulation or the...

Changes in proximate composition and lipid quality of atherina atherina sp. during sun drying process OceanDocs
Selmi, S.; Bouriga, N.; Faure, E.; Trabelsi, M..
Dans le présent travail, l’effet du séchage solaire sur la composition biochimique et la qualité des lipides des athérines a été étudié. La teneur en lipides, protéines et en cendres dans l’athérine a augmenté significativement (p <0.05) après le séchage. Cependant, celle de l’humidité a montré une forte diminution pour atteindre 22.37% dans le produit final. D’autre part, l’étude des indicateurs d’altération des lipides (Oxydation et Hydrolyse) nous a montré que la qualité des lipides des athérines est affectée par ce type de traitement. En effet, les taux des hydropéroxydes et des acides gras libres ont augmenté significativement (p < 0.05) après le séchage pour atteindre respectivement 2.02 meq active O2/kg huile et 3.67%. La formation des...

Comparison of methods for stock assessment of European hake Merluccius merluccius in the Gulf of Lions (Northwestern mediterranean) ArchiMer
Aldebert, Yvonne; Recasens, Laura.
European hake Merluccius merluccius is the main commercial demersal species in the Gulf of Lions (Northwestern Mediterranean). This fish is exploited by French and Spanish trawler fleets and by small-scale fisheries using gillnets and longlines. Data on landings and the demography of catches by type of gear are now available for the period 1988-1991. The assessment of the hake stock was carried out using methods of virtual population analysis (VPA), or cohort analysis, based respectively on mean pseudocohorts and cohorts by age. The results of these VPA were then analysed and compared from a methodological point of view. The general results have confirmed previous studies with regard to the level of exploitation of the species. The two methods gave quite...

Competing claims on natural resources become increasingly acute, with the poor being most vulnerable to adverse outcomes of such competition. A major challenge for science and policy is to progress from facilitating univocal use to guiding stakeholders in dealing with potentially conflicting uses of natural resources. The development of novel, more equitable, management options that reduce rural poverty is key to achieving sustainable use of natural resources and the resolution of conflicts over them. Here, we describe an interdisciplinary and interactive approach for: (i) the understanding of competing claims and stakeholder objectives; (ii) the identification of alternative resource use options, and (iii) the scientific support to negotiation processes...

Demand for High-value Secondary Crops in Developing Countries: The Case of Potatoes in Bangladesh and Pakistan AgEcon
Bouis, Howarth E.; Scott, Gregory.
Secondary crops are of increasing interest to policymakers and planners in developing countries because of a desire to diversify economic activities and because of their proven potential to raise farm incomes and rural employment. To assess this potential, basic information on the demand characteristics for these crops is required. But, given the large number of possible crops to be studied, policy analysts require an estimation procedure that is less data-intensive and time-intensive than standard econometric estimation procedures. In this paper, a relatively new, low-cost procedure, based on demand for food characteristics, is applied, illustrating its usefulness for analysis of demand for potatoes in Bangladesh and Pakistan. In Asia, the potato should...

Developing a methodology for assessing the economic impacts of large scale environmental regulations AgEcon
Berck, Peter; Hess, Peter.
This paper explains the development and implementation of a methodology for assessing the economic impacts of large-scale environmental regulations. The development process began with a literature review surveying channels through which environmental regulations might influence economic performance. Avenues deemed suitable were incorporated into a computable general equilibrium (CGE) model of the California economy. This model is based on the California Department of Finance's Dynamic Revenue Analysis Model (DRAM). Modifications to DRAM for the current project include a revised sectoring scheme that features industries of particular regulatory interest, revamped data matrices that accommodate this new sectoring scheme, a new air pollution module,...
