Reusando Modelos Conceituais : Linguagem e Compilador

TCC(graduação) - Universidade Federal de Santa Catarina. Centro Tecnológico. Ciências da Computação.Este relatório apresenta uma linguagem textual para modelagem con- ceitual (baseada em classes/associações da UML e em restrições da OCL) e um compilador que pode gerar código em qualquer linguagem ou tecnologia através de templates de texto extensíveis. A linguagem e o compilador permitem a especificação da informação gerenciada por sistemas de software cada vez mais distribuídos e em constante mu- dança. A partir de uma única fonte, a geração de código automática mantém as implementações consistentes com sua especificação atra- vés das diferentes plataformas e tecnologias. Além disso, na medida em que o horizonte tecnológico se expande, os templates textuais po- dem ser modificados para adotar novas tecnologias. Diferentemente de outras abordagens, tais como MDA e MPS, espera-se que o suporte fer- ramental acompanhando esta linguagem, juntamente com sua natureza textual, facilite a integração do desenvolvimento de software dirigido por modelos no fluxo de trabalho dos desenvolvedores de software

Impure Public Goods and Technological Interdependencies

Impure public goods represent an important group of goods. Almost every public good exerts not only effects which are public to all but also effects which are private to the producer of this good. What is often omitted in the analysis of impure public goods is the fact that – regularly – these private effects can also be generated independently of the public good. In our analysis we focus on the effects alternative technologies – independently generating the private effects of the public good – may have on the provision of impure public goods. After the investigation in an analytical impure public good model, we numerically simulate the effects of alternative technologies in a parameterized model for climate policy in Germany

Key Environmental Innovations

This paper is based on empirical research on a taxonomy of technological environmental innovations. It draws on a databank with over 500 examples of new technologies (materials, products, processes and practices) which come with benign environmental effects. The approaches applied to interpreting the datasets are innovation life cycle analysis, and product chain analysis. Main results include the following: 1. Innovations merely aimed at eco-efficienc y do in most cases not represent significant contributions to improving the properties of the industrial metabolism. This can better be achieved by technologies that fulfill the criteria of eco-consistency (metabolic consistency), also called eco-effectiveness. 2. Ecological pressure of a technology is basically determined by its conceptual make-up and design. Most promising thus are technologies in earlier rather than later stages of their life cycle (i.e. during R&D and customisation in growing numbers), because it is during the stages before reaching the inflection point and maturity in a learning curve where technological environmental innovations can best contribute to improving ecological consistency of the industrial metabolism while at the same time delivering their maximum increase in efficiency as well.3. Moreover, environmental action needs to focus on early steps in the vertical manufacturing chain rather than on those in the end. Most of the ecological pressure of a technology is no rmally not caused end-of-chain in use or consumption, but in the more basic steps of the manufacturing chain (with the exception of products the use of which consumes energy, e.g. vehicles, appliances). There are conclusions to be drawn for refocusing attention from downstream to upstream in life cycles and product chains, and for a shift of emphasis in environmental policy from regulation to innovation. Ambitious environmental standards, though, continue to be an important regulative precondition of ecologically benign technological innovation

Emissions Trading, CDM, JI, and More - The Climate Strategy of the EU

The objective of this paper is to assess the likely allocation effects of the current cli-mate protection strategy as it is laid out in the National Allocation Plans (NAPs) for the European Emissions Trading Scheme (ETS). The multi-regional, multi-sectoral CGE-model DART is used to simulate the effects of the current policies in the year 2012 when the Kyoto targets need to be met. Different scenarios are simulated in or-der to highlight the effects of the grandfathering of permits to energy-intensive instal-lations, the use of the project-based mechanisms (CDM and JI), and the restriction imposed by the supplementarity criterion

Urban Environmental Health and Sensitive Populations: How Much are the Italians Willing to Pay to Reduce Their Risks?

We use contingent valuation to elicit WTP for a reduction in the risk of dying for cardiovascular and respiratory causes, the most important causes of premature mortality associated with heat wave and air pollution, among the Italian public. The purpose of this study is three-fold. First, we obtain WTP and VSL figures that can be applied when estimating the benefits of heat advisories, other policies that reduce the mortality effects of extreme heat, and environmental policies that reduce the risk of dying for cardiovascular and respiratory causes. Second, our experimental study design allows us to examine the sensitivity of WTP to the size of the risk reduction. Third, we examine whether the WTP of populations that are especially sensitive to extreme heat and air pollution - such as the elderly, those in compromised health, and those living alone and/or physically impaired - is different from that of other individuals. We find that WTP, and hence the VSL, depends on the risk reduction, respondent age (via the baseline risk), and respondent health status. WTP increases with the size of the risk reduction, but is not strictly proportional to it. All else the same, older individuals are willing to pay less for a given risk reduction than younger individuals of comparable characteristics. Poor health, however, tends to raise WTP, so that the appropriate VSL of elderly individuals in poor health may be quite large. Our results support the notion that the VSL is individuated

Creative Thinking and Modelling for the Decision Support in Water Management

This paper reviews the state of art in knowledge and preferences elicitation techniques. The purpose of the study was to evaluate various cognitive mapping techniques in order to conclude with the identification of the optimal technique for the NetSyMod methodology. Network Analysis Creative System Modelling (NetSyMod) methodology has been designed for the improvement of decision support systems (DSS) with respect to the environmental problems. In the paper the difference is made between experts and stakeholders knowledge and preference elicitation methods. The suggested technique is very similar to the Nominal Group Techniques (NGT) with the external representation of the analysed problem by means of the Hodgson Hexagons. The evolving methodology is undergoing tests within several EU-funded projects such as: ITAES, IISIM, NostrumDSS

Multilateral Environmental Agreements and Trade Obligations: A Theoretical Analysis of the Doha Proposal

The Doha declaration on trade and environment proposed to clarify the relationship between multilateral environmental agreement (MEA) trade obligations and WTO rules by only guaranteeing economic integration upon ratification of certain MEAs. In other words, it pushed to authorize the use of trade measures against non-compliance, denying a non-signatory of its WTO rights to exercise countervailing tariffs. This paper demonstrates that the Doha proposal can be effective when environmental policy and its trade obligations are endogenous. Under plausible circumstances, ratification by a non-signatory to the MEA along with free trade as a reward is the unique equilibrium outcome. Delocation to pollution havens does not occur, as optimal tariffs are positive if standards are not adopted. Tariffs however only work as a credible threat and do not emerge in equilibrium. Results are consistent with broad empirical evidence that opposes the pollution haven hypothesis and suggests capital movements to be non-pollution related
