Its aim is to study the extent to which the industry and its stakeholders are aware of the existence of such services in order to be able to prioritize them with respect to social well-being. This identification phase is seldom discussed. It requires that survey questionnaires be designed so as to improve understanding of these perceptions. The surveys undertaken combined both open questions where the interviewees expressed their perceptions spontaneously and closed questions where they were invited to rank a pre-established list of the relevant services. These surveys involved 133 fish farmers and 93 stakeholders. The results show that perceptions differ by question type, and confirm the significance of the questionnaire design and the importance of combining several kinds of approach.展开更多

PES schemes often have high opportunity costs in terms of foregone uses of goods and services offered by the environment. It is within this scope that economic evaluation of environmental goods and services plays a role. In this paper we surveyed articles and studies that report application of economic environmental valuation procedures in PES schemes. Special attention was paid to data collection and analysis, to theoretical robustness of its procedures and to the aggregation of estimated value. We also scrutinize how these estimates had been incorporated into PES schemes, in particularly in the assessment phase of these schemes. Empirical data from Brazil and other Latin American countries were used, particularly those in the Amazon Basis. Our results reveal a frequent overestimation of the values of ecosystem services calculated through the use of economic valuation methods. Values have been estimated by production function methods （opportunity cost, preventive expenditures, recovering cost or dose-response methods）. As a consequence, estimated values reflect much more willingness to accept compensation by supplier and rarely willingness to pay by consumer of these ecosystem services. Besides this distance between supply and demand, application of valuation methods did not account for problems such as uncertainty, risks, and lack of information. All these limitations have led to wrong decision-making.展开更多

Models of the national ancillary services markets are market models which offer transmission system operator efficient procurement of ancillary services, reducing the system management risk, more competitive electricity market, better utilization of production facilities and complete deregulation of electricity markets. This paper deals with current mode of ancillary services market and potential market development in Croatia. Described models are used for establishing market of ancillary services which should occur in parallel with the electricity market.展开更多

By reviewing a variety of literature and using statistics, the paper ascertains notable impediments such as the absence of standard protocols, lack of adequate technological infrastructure, and weak regulatory frameworks. Resultant effects from these challenges regarding health provision target enhanced data sharing and merging for better patient outcomes and allocation of resources. It also highlights several opportunities that include the adoption of emerging technologies, and the establishment of public-private partnerships to strengthen the healthcare framework among others. In this regard, the article provides recommendations based on stakeholder views and global best practices addressed to policymakers, medical practitioners, and IT specialists concerned with achieving effective interoperability within Kenya’s health system. This research is relevant because it adds knowledge to the existing literature on how healthcare quality can be improved to make it more patient-centered especially in Kenya.展开更多
