Firms’ Private Action Towards Environmental Quality: Where Does Regulation Stand for Non-Adopters of Environment Management Practices?
Full text linkThis study examines the effects of regulatory framework and legal system on the private action towards environmental quality among food processing firms in Sri Lanka. An Environment Regulation Responsiveness Index, reflecting compliance to solid waste management practices, was used as the measure of firms perception on environment regulation. The results highlight that compliance by the majority of firms was relatively low, especially among the small scale firms, suggesting that the decision maker on environment quality did not consider government regulation as an impotant factor to act on the environment. This calls for a critical revision and adjustments to the policy on environmental quality management both at the national and provincial level in order to promote voluntary action by firms

Full text linkUrban Coastal Ecosystem Services and Value of Cultural Landscape: An Assessment of View Value to the Indigenous Fishing Community
Full text linkBenefits from an ecosystem to support sustainable human well-being-commonly referred to as ‘ecosystem services’-are basically categorized into four major groups such as “Provisioning”, “Regulating”, “Cultural” and “Supporting”. In environmental valuation studies, these have often been taken as a bundle of services and the individual value of certain attributes such as Cultural services, which accounts for non-material benefits people obtain from ecosystems, were largely overlooked. The purpose of this study was to assess the value of cultural landscape of an urban coastal ecosystem, which is made out of two categories (i.e. urban systems and coastal systems) specified under the ‘ten system classification of millennium ecosystem assessment’. Negombo lagoon was selected as the study site, and the view of the site was justified to explain the cultural landscape of lagoon in concern. Admitting those inherent difficulties associated with defining the cultural landscape, this was slender down into few values, namely: aesthetic, social relations, sense of place, and cultural heritage values. The lagoon area is geographically segregated into areas known as “Thotupola” where the fisherman used to launch their fishing boats. Choice Method was applied to assess the community preferences for lagoon view to which the ‘attributes’ and ‘levels’ identified through the pilot survey were used. There were number of lagoon front properties as lagoon provides many other amenities. Therefore view was classified into three levels as “full view” (unobstructed lagoon view), “partial view” (some obstruction by buildings and trees) and “no view” (fully obstructed or no view can be seen). Face-to-face interviews supported by a structured questionnaire were carried out with 300 respondents representing 15 ‘Thotupola’ areas to collect data. The level “no view” was omitted as the dummy variable; “full” and “partial” view were combined to value the cultural landscape. The outcome of analysis shows that the Marginal willingness-to-pay (MWTP) for cultural landscape is Rs. 309.50. Further, the lagoon view had significant impact on implicit price of overall ecosystem services in terms of both ‘full’ (Rs. 161.50) and ‘partial’ (Rs. 148.50) view. The overall implicit price for the ecosystem services is derived as Rs. 1062.75. Cultural landscape account solely 30 percent from whole ecosystem value that cannot readily provide a substitute to the indigenous people in community. Therefore in formulating conservation policies and exploiting land development activities the policy makers must account the fact and importance of cultural landscape of an ecosystem to the indigenous people in community.Keywords: Choice Methods, Cultural landscape, Negombo lagoon, Urban ecosystem services, Value of vie

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
