Principles for Fairness and Efficiency in Enhancing Environmental Services in Asia: Payments, Compensation, or Co-Investment?

The term payments for environmental services (PES) has rapidly gained popularity, with its focus on market-based mechanisms for enhancing environmental services (ES). Current use of the term, however, covers a broad spectrum of interactions between ES suppliers and beneficiaries. A broader class of mechanisms pursues ES enhancement through compensation or rewards. Such mechanisms can be analyzed on the basis of how they meet four conditions: realistic, conditional, voluntary, and pro-poor. Based on our action research in Asia in the Rewarding Upland Poor for Environmental Services (RUPES) program since 2002, we examine three paradigms: commoditized ES (CES), compensation for opportunities skipped (COS), and co-investment in (environmental) stewardship (CIS). Among the RUPES action research sites, there are several examples of CIS with a focus on assets (natural + human + social capital) that can be expected to provide future flows of ES. CES, equivalent to a strict definition of PES, may represent an abstraction rather than a current reality. COS is a challenge when the legality of opportunities to reduce ES is contested. The primary difference between CES, COS, and CIS is the way in which conditionality is achieved, with additional variation in the scale (individual, household, or community) at which the voluntary principle takes shape. CIS approaches have the greatest opportunity to be pro-poor, as both CES and COS presuppose property rights that the rural poor often do not have. CIS requires and reinforces trust building after initial conflicts over the consequences of resource use on ES have been clarified and a realistic joint appraisal is obtained. CIS will often be part of a multiscale approach to the regeneration and survival of natural capital, alongside respect and appreciation for the guardians and stewards of landscapes

What words mean and express: semantics and pragmatics of kind terms and verbs

For many years, it has been common-ground in semantics and in philosophy of language that semantics is in the business of providing a full explanation about how propositional meanings are obtained. This orthodox picture seems to be in trouble these days, as an increasing number of authors now hold that semantics does not deal with thought-contents. Some of these authors have embraced a “thin meanings” view, according to which lexical meanings are too schematic to enter propositional contents. I will suggest that it is plausible to adopt thin semantics for a class of words. However, I’ll also hold that some classes of words, like kind terms, plausibly have richer lexical meanings, and so that an adequate theory of word meaning may have to combine thin and rich semantics

Abductive two-dimensionalism: a new route to the a priori identification of necessary truths

Epistemic two-dimensional semantics, advocated by Chalmers and Jackson, among others, aims to restore the link between necessity and a priority seemingly broken by Kripke, by showing how armchair access to semantic intensions provides a basis for knowledge of necessary a posteriori truths. The most compelling objections to E2D are that, for one or other reason, the requisite intensions are not accessible from the armchair. As we substantiate here, existing versions of E2D are indeed subject to such access-based objections. But, we moreover argue, the difficulty lies not with E2D but with the typically presupposed conceiving-based epistemology of intensions. Freed from that epistemology, and given the right alternative—one where inference to the best explanation provides the operative guide to intensions—E2D can meet access-based objections, and fulfill its promise of restoring the desirable link between necessity and a priority. This result serves as a central application of Biggs and Wilson, according to which abduction is an a priori mode of inference

Conceivability and Modal Knowledge

Christopher Hill contends that the metaphysical modalities can be reductively explained in terms of the subjunctive conditional and that this reductive explanation yields two tests for determining the metaphysical modality of a proposition. He goes on to argue that his reductive account of the metaphysical modalities in conjunction with his account of modal knowledge underwrites the further conclusion that conceivability does not provide a reliable test for metaphysical possibility. I argue (1) that Hill’s reductive explanation of the metaphysical modalities in terms of the subjunctive conditional does not yield a reductive explanation of knowledge of metaphysical modality in terms of knowledge of subjunctive conditionals, and (2) that his account of modal knowledge is at odds with his contention that conceivability does not provide epistemic access to metaphysical possibility

Tentative first steps : an assessment of the Uruguay Round agreement on services

A major result of the Uruguay Round was the creation of a General Agreement on Trade in Services (GATS). The GATS greatly extends coverage of the multilateral trading system, establishing rules and disciplines on policies affecting access to service markets. In this paper, the author asks: what does the GATS do to bind policies? And has it established a mechanism likely to induce significant liberalization through future rounds of negotiations? The GATS consists of two elements: 1) a set of general concepts, principles, and rules that apply across the board to measures affecting trade in services; and 2) specific commitments on national treatment and market access. These apply only to service activities listed in a member's schedule - reflecting the agreement's"positive-list"approach to determining coverage - and only to the extent that sector-specific or cross-sectoral qualifications or conditions are not maintained. The impact of the GATS depends largely on the specific commitments made by members, and sectoral coverage is far from universal. High-income countries scheduled about half of their service sectors; developing countries as a group (including Eastern European countries in transition) scheduled only 11 percent. And the sectors scheduled often continue to be subject to measures that violate national treatment or limit market access. High-income countries scheduled only 28 percent of the universe of services without exceptions to national treatment or market access obligations. For developing countries, that figure is only 6.5 percent. Much remains to be done. The GAT's weaknesses include: 1) a lack of transparency. No information is generated on sectors, subsectors, and activities in which no commitments are scheduled - most often the sensitive areas where restrictions and discriminatory practices abound; 2) the sector-specificity of liberalization commitments. Negotiations were driven by the concerns of major players of each industry, leading to an emphasis on"absolute"sectoral reciprocity, limiting the scope for incremental liberalization, tradeoffs across issues, and an economywide perspective; and 3) the limited number of generic rules. Rather than lock in liberal situations that exist, the GATS allows for the future imposition of restrictions (creating"negotiating chips"). To foster nondiscriminatory liberalization, sectoral agreeements should be firmly imbedded in a framework of general rules and disciplines. Many of the framework's general principles apply only if specific commitments have been made. Therefore they are not general. Proposals for improving the GATS should probably build on the existing structure as mush as possible. Possibilities include the following: 1) ultimately, apply the same rules to goods and services. Eliminate the artificial distinction between the two; 2) adopt a negative-list approach to scheduling commitments for the sake of transparency; 3) eliminate overlap between national treatment and market access; 4) develop generic,"horizontal"disciplines for the different modes of supply through which service markets may be contested; 5) explore the possibility of converting quota-like market access restrictions to price-based equivalent measures, thus ensuring that the most-favored-nation and national treatment principles are satisfied; 6) make framework disciplines general by eliminating all instances in which rules are conditional on the scheduling of specific commitments; and 7) agree to a formula-based approach for liberalizing and expanding the GAT's sectoral coverage in future negotiations.Economic Theory&Research,Environmental Economics&Policies,Payment Systems&Infrastructure,Decentralization,Health Economics&Finance,Health Economics&Finance,Economic Theory&Research,Trade and Services,TF054105-DONOR FUNDED OPERATION ADMINISTRATION FEE INCOME AND EXPENSE ACCOUNT,ICT Policy and Strategies

Python for teaching introductory programming: A quantitative evaluation

This paper compares two different approaches of teaching introductory programming by quantitatively analysing the student assessments in a real classroom. The first approach is to emphasise the principles of object-oriented programming and design using Java from the very beginning. The second approach is to first teach the basic programming concepts (loops, branch, and use of libraries) using Python and then move on to oriented programming using Java. Each approach was adopted for one academic year (2008-09 and 2009-10) with first year undergraduate students. Quantitative analysis of the student assessments from the first semester of each year was then carried out. The results of this analysis are presented in this paper. These results suggest that the later approach leads to enhanced learning of introductory programming concepts by students

Issues of shaping the students’ professional and terminological competence in science area of expertise in the sustainable development era

The paper deals with the problem of future biology teachers’ vocational preparation process and shaping in them of those capacities that contribute to the conservation and enhancement of our planet’s biodiversity as a reflection of the leading sustainable development goals of society. Such personality traits are viewed through the prism of forming the future biology teachers’ professional and terminological competence. The main aspects and categories that characterize the professional and terminological competence of future biology teachers, including terminology, nomenclature, term, nomen and term element, have been explained. The criteria and stages of shaping the future biology teachers’ professional and terminological competence during the vocational training process have been fixed. Methods, techniques, technologies, guiding principles and forms of staged work on the forming of an active terminological dictionary of students have been described and specified. The content of the distant special course “Latin. Botanical Terminology”, which provides training for future teachers to study the professional subjects and to understand of international scientific terminology, has been presented. It is concluded that the proper level of formation of the future biology teachers’ professional and terminological competence will eventually ensure the qualitative preparation of pupils for life in a sustainable development era
