    The Operators Aγ = γA + -γA for a Class of Nondissipative Operators A with a Limit of the Corresponding Correlation Function

    2000 Mathematics Subject Classification: Primary 47A48, Secondary 60G12In this work we present the operators Aγ = γA + -γA with Re γ = 1/2 in the case of an operator A from the class of nondissipative operators generating nonselfadjoint curves, whose correlation functions have a limit as t → ±∞. The asympthotics of the stationary curves e^(itAγ)f as t → ±∞ onto the absolutely continuous subspace of Aγ are obtained. These asymptotics and the obtained asymptotics in [9] of the nondissipative curves e^(itA)f allow to construct the scattering theory for the couples (Aγ , A) and (A, Aγ). We consider the basic terms from the scattering theory - wave operators, a scattering operator and the question of a similarity of A and Aγ. We obtain explicitly the wave operators, the scattering operator and the similarity of A and Aγ.Partially supported by Grant MM-810/98 of MESC and by Scientific Research Grant 21/09.05.2001 of Shumen University

    Incentives for Residential Water Conservation: Water Price, Revenue, and Consumer Equity in Florida

    Get PDF
    Economic theory suggests that price incentives can be used to encourage water conservation in residential consumers. Conservation water rates are designed to send price signals that encourage households to reduce discretionary water use in the long term. However, it is not always clear that conservation rates effectively provide meaningful incentives. Utilities themselves may also not have strong incentives to implement conservation rates. If conservation rates have a negative impact on revenue, or if they lead to increased revenue variability, utilities may have a disincentive to use them. In addition, block pricing structures (where unit water rate increases with water usage) may be inequitable, in the sense that the “revenue burden” is borne disproportionately by some customer groups. This may make some rate structures unpopular with consumers and politically unfeasible. Because there is no consensus about what defines conservation rates, they take many forms. In Florida, the two most common are: uniform rates- where customers pay a set fee for each unit of water used, and inclining block rates- where the price per unit becomes progressively higher. Empirical evidence about the incentives provided by various structures is limited. This research has three main objectives. The first is to analyze whether or not the number of price blocks affects the conservation incentives faced by residential consumers. The second is to test for statistical evidence that rate structure effects revenue variability. And, the third is to analyze the impact of different rate structures on consumer equity. Secondary data from sixteen Florida utilities are used to meet the objectives of the study. The sample was originally chosen by Dr. John Whitcomb as a part of his study Florida Water Rates Evaluation of Single-Family Homes (2005). Whitcomb (2005) includes rate information, customer survey results, and empirical data on actual water use for 7,200 households from 1998 to 2003. For the first objective, a descriptive analysis of rate structures is used. Household reductions in water use are compared to corresponding reductions in water bills for all rate structure periods. Larger reductions in corresponding bills indicate stronger conservation price signals. Distribution of utility revenues between volumetric and fixed water and wastewater charges is also examined, and larger share of volumetric charges is linked to a stronger conservation price signal. The second part of the study uses graphical analysis and a simple OLS model to examine rate structure and revenue variability. For the third objective, Gini coefficients and Lorenz curves were used, following Morgan (1987). Households are divided into income groups and usage groups. Gini Coefficients are calculated based on these groups. Lower coefficients indicate a more equitable rate structure. The results indicate that the conservation price signals are strongest for inclining block structures with more than three price blocks. Block structures with three or less price blocks do not send stronger price signals than uniform rate structures. In some cases, the price incentive to reduce water consumption by 40% was stronger for uniform structures than for inclining block structures with three blocks. Within the sample, the price incentive is strongest for inclining block structures with more than three price blocks. Alternatively, the utility revenue distribution results suggest that the number of price blocks is not necessarily a good indicator of how conservation oriented a rate structure is. In several cases, the percentage of revenue from volumetric sources was higher for uniform structures than for block structures. Analysis for objectives two and three will be completed in October 2009. Preliminary results for objective two provide evidence that revenue variability could be a significant disincentive for utilities to adopt conservation rates. While there was no statistical evidence that overall revenue is affected by changes in rate structure, there is some evidence that utility revenue streams are more variable for block structures than for uniform structures. Preliminary objective three results suggest that customer equity is not adversely affected by conservation rates. When divided into income groups, the estimated Gini coefficients for uniform and inclining block rate structures were similar and close to zero, indicating equitable pricing.Conservation, water, price, revenue, equity, Community/Rural/Urban Development, Consumer/Household Economics, Demand and Price Analysis, Environmental Economics and Policy,

    Performance assessment of Russian homeowners associations : The importance of being social

    Get PDF
    Performance of Russian homeowners associations – non-profits established to manage common property in residential housing – is assessed using the stochastic frontier technique, which is a powerful tool of productivity analysis. Performance variations are explained by physical and social factors, prominent among them is the availability of social capital among tenants, required to resolve collective action problems and ensure accountability of managing bodies and outside contractors. Lack of civic capacity could be an obstacle to implementing community-governance solutions in residential housing, making homeowners associations dysfunctional or prone to capture by vested interests.homeowners associations; non-profit organizations; common property; stochastic frontier; social capital

    Semiotic aspects of architectural graphic's History

    Get PDF
    [Abstract]The subject of this thesis are the semiotic aspects of the architectural graphics' history. It is suggested that the main expressive system in the architecture design - „architectural graphics“ is to be given a new meaning in the light of semiotics, as a contemporary science paradigm. The history of the architectural drawings is to be examined as a history of a system of signs, as a growth and development of an original architectural language. The aim of this paper is to prove the necessity and also to test the limits and the range of this research area. The study must altogether present the historical base of the architectural drawing systems and to analyze the concentration of graphics’ meanings, comparing to the contemporary elements in the design process. It shall also follow the existing ways of transferring architectural information, according to the audience, the culture and the building methods of the historical period. The study will focus over the communication processes in the architectural design, and will examine the key points of decoding and apprehending the architectural experience. The results of this study are expected in the fields of architectural history and education, same as in the area of visual and especially architectural semiotics. The value of this paper is to give a referance point for the future semiotics research over the architectural graphics, and another studies in the field of architectural semiotics
