Adaptive and integrative governance on risk and uncertainty

Abstract: The article will conceptualize procedural mechanisms and structural configurations of risk governance with adaptive and integrative capacity in a general and comprehensive manner in order to better grasp the dynamics, structures, and functionality of risk-handling processes. Adaptive and integrative risk governance is supposed to address challenges raised by three characteristics that result from a lack of knowledge and/or competing knowledge claims about the risk problem: complexity, scientific uncertainty, and socio-political ambiguity. Adaptive and integrative capacity are broadly seen as the ability of politics and society to collectively design and implement a systematic approach to organizational and policy learning in institutional settings that are conducive to resolve cognitive, evaluative and normative problems, and conflicts of risks. For this purpose, we propose a risk governance model that augments the classical model of risk analysis (risk assessment, management, communication) by including ...

Polyphenolics extracts from legume seeds: correlations between total antioxidant activity, total phenolics content, tannins content and astringency

Abstract: Extracts of polyphenolic compounds were obtained from seeds of faba bean, broad bean, adzuki bean, red bean, pea, red lentil and green lentil using 80% (v/v) acetone. The total antioxidant activity (TAA) of extracts was determined and their astringency (Sensation Astringency Indices – SAI) investigated using the sensory scaling method. The content of tannins in extracts was expressed as absorbance values at 500 and 550 nm after color developed with vanillin/HCl reagent and after n-butanol-HCl hydrolysis, respectively. A statistically significant correlation was found between the TAA values and total phenolics (P = 0.01), TAA and tannins determined by vanillin method (P = 0.05), TAA and tannins determined after n-butanol-HCl hydrolysis (P = 0.05), SAI values and tannins determined with vanillin method (P = 0.10), SAI values and tannins determined after n-butanol-HCl hydrolysis (P = 0.05), SAI values and total phenolics (P = 0.01), total phenolics and tannin content determined by vanillin method (P = 0.01), total phenolics and tannin content determined after n-butanol-HCl hydrolysis (P = 0.05), tannins determined with vanillin method and tannins determined after n-butanol hydrolysis (P = 0.02).

Loss of Fish Habitat as a Consequence of Inappropriately Constructed Stream Crossings

Abstract: In the light of declines in Atlantic salmon (Salmo salar) stocks, we sought to determine the extent to which stream crossings along a newly constructed section of the Trans Labrador Highway (TLH Phase II) in southern Labrador accorded with government regulations for fish habitat protection. We surveyed crossings of permanent streams over a 210 km road segment, containing 4 bridges and 47 culverts. Fifty-three percent of culverts posed problems to fish passage, due to poor design or poor installation. We conjecture that cost and inadequate environmental oversight in the field explain the weak compliance with the relevant fisheries guidelines. Our research has prompted the federal regulator to instigate remediation of problems with the Phase II part of the highway. In addition many of the planned stream crossings for Phase III of the TLH were re-designed, and a commitment to careful monitoring of the installations has been made by the federal regulator in cooperation with the indigenous inhabitants.

Integrated inherent safety index (I2SI): A tool for inherent safety evaluation

Abstract: Inherent safety is a proactive approach for loss prevention and risk management. Considering the lifetime costs of a process and its operation, an inherent safety approach can lead to a cost-optimal option. Inherent safety may be achieved at any stage of process design; however, its application at the early stages of process design yields the best results. Despite being an attractive and cost-effective approach, the inherent safety methodology is not widely used. Many reasons have been attributed to this lack of widespread use; the nonavailability of systematic tools for the application of inherent safety principles is perhaps the most important reason. This paper presents a conceptual framework of an integrated inherent safety index (I2SI). It is called an integrated index because the procedure, when fully developed, is intended to consider the life cycle of the process with economic evaluation and hazard potential identification for each option. The I2SI is composed of subindices which account for hazard potential, inherent safety potential, and add-on control requirements. An application of the I2SI is also discussed. © 2004 American Institute of Chemical Engineers Process Saf Prog 23: 136–148, 2004
