Throughout early modern Europe, one of the most extraordinary royal fund-raising schemes was the seizure and sale of church property to finance foreign wars. The monarchs of Habsburg Spain extended these seizures to municipal property and used the revenue to maintain their empire. They sold charters of autonomy to hundreds of villages, thus converting them into towns, and sold towns to private buyers, thus increasing the number of seigniorial lords. In Hapsburg Spain, therefore, absolutism did not mean centralization. Rather, the kings invoked their absolute power to decentralize authority and allow their subjects a surprising degree of autonomy.
Various ways of financing health care expenditures by communities are studied in this chapter. The first method is direct payments by patients for drugs. Application of this method presupposes that other health care expenditures are financed by other agents such as international donors and central, district or local government. A fee-for-service arrangement constitutes the second method. This is more general in that fees may cover other recurrent expenditures as well as drug expenditures. Salaries of health personnel and depreciation allowances may also be included in a fee-for service system. The third method consists of prepayments for health care or decentralized forms of health insurance. Finally, we consider community labour as a means of financing health expenditures. In the last section, evaluation criteria for projects in community financing are examined.

IntroductionThe challenge for land use management in the nineties is to initiate a people- centered development process which creates opportunities for local people to make their own choices about which development strategy to follow. This need is felt in particular for upland areas where government initiated blue- print programmes for land use management have a record of failure. The major reason is that these programmes are often not adjusted to cope with the complexity and diversity of the uplands. Land use management encompasses both short-term and longterm benefits and is confronted with rapid changes. The differing role of private, state and communal lands in combination with a complex system of control and utilization makes land use management difficult to fully understand. This study responds with the development of an alternative strategy for planning sustainable land use programmes at local level and has the following objectives:- to develop a strategic model for people-centered planning of sustainable land use programmes;- to develop a flexible planning method that can serve as land use management tool at local level;- to test the feasibility of the strategy for the uplands of East Java, Indonesia.Strategic modelThe two major principles of the strategic model are:- Programmes are planned and implemented through a learning process in a local and organizational dimension. The local dimension includes a learning process of planning, implementing and monitoring of small scale programmes. The planning process is short, but planned interventions are regularly adjusted based on new insights and changing conditions. In the organizational dimension the learning process proceeds through three different phases of trial, development and expansion. In this dimension, the government can learn how to manage the strategy of implementing local level planning and how to change attitudes, norms and organizational competence of organizations in order to do so. This dimension embraces local, regional and national governments.- Three major variables have to be considered in programme planning: land use system; interventions and organizations. Sustainable land use programmes are only possible if a good fit between these variables is achieved.In the strategic model these two principles are combined; a fit between the variables is achieved through a learning process. Because achieving a fit between the three variables is a complicated matter, it requires a phased approach which consists of the following three steps: a trial phase, a development phase and an expansion phase. In the trial phase, the focus is on achieving a fit between interventions and land use system in the local dimension. This is achieved through the implementation of trial cases in local level planning in which villagers, field workers of organizations and local leaders become acquainted with this new approach of planning sustainable land use programmes at a local level. In the development phase, attention is focused on achieving a fit between organizations and land use system. Through the development of human resources and extension processes the skills and attitudes of those involved may gradually change to become more people-oriented. In the expansion phase the focus is on achieving a fit between interventions and organization. In this phase the planning approach is accepted and applied at a national level. Changes in government structures and procedures, such as decentralization and strengthening of local leadership need to be achieved. By dividing the process into phases, the complex problems associated with planning sustainable land use become manageable, and step by step the ultimate goal of achieving a fit between all three variables can be reached.Planning methodIn order to reach an optimal fit between the three variables of the strategic model in the trial phase, a planning method should be applied to collect and analyse data that can be transformed into the design of effective programmes. No 'off-the-peg' planning method is available, instead a combination of existing approaches, methods and techniques is needed.Three development approaches can be distinguished to this end: planning of land use development; extension approaches and project management approaches. Generally speaking, each approach covers a different side of the strategic model. Land use development focuses on achieving a fit between interventions and land use system; extension processes can be used in achieving a fit between land use system and organizations; and the fit between interventions and organizations can be accomplished with the help of project management techniques.For planning land use development in the trial phase a number of current methods and techniques are discussed. These are Farming System Analysis, Land Evaluation, Agroecosystem Analysis, Landscape Planning, Rapid Rural Appraisal and Gender Analysis. The criteria set by the strategic model determine which aspects of these present planning methods and techniques are useful for the development of a new planning method. None of these methods and techniques as such are ideal as an operational planning method for realizing the first phase of the strategic model. A synthesis of all useful features into a new land use planning method is proposed.For the trial phase the focus is on planning land use development while opportunities to develop extension processes and to influence project management are limited. Therefore plans should basically be tailored to the existing competence of organizations. Within these limitations some attention can be paid to extension processes and management techniques by introducing an additional step to land use planning, called programming which includes the preparation of a detailed design and a programme planning matrix.Planning environment on JavaThe environment for the planning of land use development programmes is diverse and complex in the uplands of East Java. Farmers react to the wide diversity in the land use system by developing a large number of different land use strategies. By contrast, government organizations use standardized programmes with uniform and mostly inflexible procedures for planning and implementation. Village development planning procedures exist, but do not yet function properly. Local organizations responsible for village development planning do not yet possess the skills and capability to develop such plans, and centrally organized sectoral agencies still dominate this 'bottom-up' planning process. The dominance of the central government can be explained by the incorporation of a number of socio-cultural features in their policy, such as the principles of 'sole authority', consensus, and harmony. The government uses these principles to encapsulate autonomous local organizations in the government administration, orienting the local leaders more to government rules and procedures than to the needs of the local population.This orientation towards government administration has two major implications for the current planning of interventions. Firstly, the interventions are adjusted to the competence of implementing organizations rather than letting the organizations develop their competence to implement the tasks of locally planned interventions. Secondly little more than lip-service is paid to the participation of villagers in planning.Notwithstanding these shortcomings in the present village development planning process, official government policy has some room for improvement. This may allow for a more balanced planning process new approach.Secondly, constraints which can be expected while applying the model on Java are described. The feasibility of the trial phase of the strategy is evaluated based on experiences with implementing the trial cases on Java. In this evaluation the question is raised as to what extent the results of local level planning on Java can respond to the research objectives as formulated at the start of this study. No experience has been gained as yet with implementing the development and expansion phase. One programme that provides some valuable lessons for the feasibility of the phased learning process of the strategic model is the Java Social Forestry Programme (JSFP). This programme has followed a comparable phasing strategy and has already reached the expansion phase.Conclusions and policy recommendationsThis evaluation results in a number of conclusions on conditions to be fulfilled for successful implementation of the strategy. To sum up:- although the strategy is aimed at the local level, it cannot be realized at local level only as it requires involvement of regional and national government organizations to deal with changing communication processes and organizational structure;- objectives in village development planning should be set realistically in the knowledge that short term results will always dominate long term benefits, tangible results will get higher priority than social changes, while top-down influences from sectoral agencies will prevail;- in addressing the organizational dimension a choice should be made between following an approach of 'decentralized trial cases' versus 'centrally guided bottom-up process'. Whichever strategy is chosen it needs careful management to avoid difficulties in institutionalization or a too rapid expansion respectively;- it is necessary for the government to be shown better results in terms of sustainable land use development programmes at local level implemented by highly committed villagers. Only then may they be motivated to accept such a participatory approach at the cost of losing some power or consensus;- implementing a participatory planning process is an initially slow process, to which government agencies need to be committed.These conditions are translated into a number of policy recommendations for donor agencies and governments pertaining to: long-term and continuous com
We look at the question of how powerful a prover must be to give a zero-knowledge proof.We present the first unconditional bounds on the complexity of a statistical ZK prover.The result is that if a language possesses a statistical zero-knowledge then it also possesses a statistical zero-knowledge proof in which the prover runs in probabilistic, polynomial time with an NP oracle.Previously this was only known given the existence of one-way permutations. Extendingthese techniques to protocols of knowledge complexity k(n) >0, we derive bounds on the time complexity of languages of "small" knowledge complexity.Underlying these results is a technique for efficiently generating an "almost" random element of a set S E P.Namely, we construct a probabilistic machine with an NP oracle which, on input 1" and 6 > 0 runs in time polynomial in n and lg 6-1, and outputs a random string from a distribution within distance 6 of the uniform distribution on S n {O, l}~.
In order to describe adequately the national organization of police, it is necessary to distinguish the number of autonomous forces, the coordination of jurisdictions among them, and the territorial and functional distribution of commands within them. Among the five English-speaking countries of Australia, Canada, Great Britain, India, and the United States, the number as well as the coordination of forces varies sharply. As a result, differences in scale are so great as to call into question the value of using either forces or police stations as units of managerial analysis. Surprisingly, the scale of jurisdictions does not affect the number of command levels within forces. One implication of this is that the concept of centralization/decentralization must be grounded in considerations of scale. Differences in national structures of policing depend on political settlements achieved at the time countries were formed. Differences in functional organization are smaller among countries than structural ones, and they depend on professional outlooks shared internationally. Finally, very little is known about the effects of police organization on goals and objectives. The entire subject is shrouded in unexamined assumptions often unintelligently applied.
A zero-knowledge proof system of knowledge is a protocol between two parties called the prover and the verifier. The prover wants to convince the verifier that he “knows” the proof of a given theorem without revealing any additional information. This is different from a zero-knowledge proof system of membership where the prover convinces the verifier only of the veridicity of the statement. Zero-knowledge proofs of knowledge are very useful tools in the design of secure protocols. Though, the concept of a proof of knowledge is a very subtle one and great care is needed to obtain a satisfying formalization. In this paper, we investigate the concept of a zero-knowledge proof of knowledge in the noninteractive model of [5, 61. Here, the prover and the verifier share a short random string and the only communication allowed is from the prover to the verifier. Although this is a simpler model than the interactive one, still formalizing zeroknowledge proofs of knowledge is a delicate task. The main results of the paper are the following e We present formal definitions for the concept of non-interactive zero-knowledge proofs

In this note, we present new zero-knowledge interactive proofs and arguments for languages in NP. To show that x ε L, with an error probability of at most 2-k, our zero-knowledge proof system requires O(|x|c1)+O(lgc2|x|)k ideal bit commitments, where c1 and c2 depend only on L. This construction is the first in the ideal bit commitment model that achieves large values of k more efficiently than by running k independent iterations of the base interactive proof system. Under suitable complexity assumptions, we exhibit zero knowledge arguments that require O(lgc|x|kl bits of communication, where c depends only on L, and l is the security parameter for the prover. This is the first construction in which the total amount of communication can be less than that needed to transmit the NP witness. Our protocols are based on efficiently checkable proofs for NP[4].

This document reports the findings of an examination of a variety of state government efforts to assist local government in obtaining infrastructure, particularly water supply, wastewater treatment, and solid waste disposal facilities. The project team sought examples of innovative practices that could serve as models for other state and local agencies. The scope of this effort did not permit the team to evaluate in-depth these state programs. The information is presented under nine topics, which are also chapter heading for chapters 2 through 10: (2) terms and conditions, and special requirements; (3) scope of financial assistance programs; (4) project selection process; (5) providing technical assistance; (6) decentralized decision-making; (7) bond banks; (8) monitoring and evaluation; (9) assessing statewide future needs; and (10) privatization. The first chapter is an introduction to the report and the final chapter (11) contains recommendations to the Federal government.

This paper investigates the possibility of disposing of interaction between prover and verifier in a zero-knowledge proof if they share beforehand a short random string. Without any assumption, it is proven that noninteractive zero-knowledge proofs exist for some number-theoretic languages for which no efficient algorithm is known. If deciding quadratic residuosity (modulo composite integers whose factorization is not known) is computationally hard, it is shown that the NP-complete language of satisfiability also possesses noninteractive zero-knowledge proofs.
Finding the proper balance between central control and local autonomy is a perennial problem in the Chinese economy, and the Chinese fiscal system has undergone numerous changes in central-provincial revenue-sharing arrangements since the 1950s. In the post-Mao period, fiscal decentralization began in 1980 under the slogan of “cooking in separate kitchens” ( fenzao chifan ), and a series of reforms was implemented to put local governments increasingly on a self-financing basis. However, this attempt to revamp the financial interaction between the central and provincial governments has been made immensely more complicated by rapid changes in the fiscal system and the shifting composition of revenues and expenditures brought by economic reform.
After providing… [public expenditure] … theory with its… optimal conditions, I went on to demonstrate the fatal inability of any decentralized market or voting mechanism to attain or compute this optimum [Samuelson, (1955), p. 35]. … to say that market mechanisms are non-optimal, and that there are difficulties with most political decision processes, does not imply that we can never find new mechanisms of a better sort [Samuelson (1958), p. 334]. Providing the [public] expenditure in question holds out any prospect at all of creating utility exceeding costs, it will always be theoretically possible, and approximately so in practice, to find a distribution of costs such that all parties regard the expenditure as beneficial and may therefore approve it unanimously [Wicksell (1896), pp. 89-90]. How much of this [the principle of unanimity and voluntary consent in taxation] … may be of practical use in the near future, men of affairs may decide [Wicksell (1896), p. 73]. INTRODUCTION The theory of public goods has, in the space of 20 years, revolutionized teaching and research in public finance, had a major impact on the content of microeconomic theory in general, and has provided, for many, the analytical foundation for an economic justification for the state. The most widely accepted proposition in contemporary public finance is the “fatal inability” of decentralized market or voting institutions to attain a Pareto-optimal allocation of resources when there are public goods.

The Heart Smart Family Health Promotion Program is a multidisciplinary, school-based program for cardiovascular risk reduction among high-risk children and their families. As a program that includes young adults at high risk, it is adaptable to a clinical practice. Nineteen fourth and fifth graders were selected as probands for elevated risk factors after a general screening to identify families for an intervention program. Twenty-three parents participated in a 12-week program focused on eating, exercise, and smoking behavior changes enhanced by behavicral support strategies. Weekly sessions were held in the auditorium/cafeteria of the elementary school and consisted of orientation and presentations, cardiovascular (CV) screening with medical feedback, activities, self-monitoring, counseling, and contingency contracting. Information gathered before and after the program included medical history, CV health knowledge and relevant behavior, blood pressure, serum lipid and lipoprotein values, anthropometric measurements, and urine electrolyte excretion. Both children and parents showed positive changes in eating habits and physical activity and significant changes in knowledge and blood pressure levels, while the children halted their weight gain. We believe this multidisciplinary, behavior-oriented, school-based program can be an effective cardiovascular risk intervention adaptable for a clinical office practice.
Local government Gordon Hughes and Stephen Smith Many OECD countries are uncomfortable with the structure and financing of their decentralized governments. In some, the pressures for change have even led to tax revolts. Much of the existing economic literature on decentralization considers that the purpose of local governments is to decentralize decisions. Lower tiers of government are assigned local public goods and matching taxes. This contrasts with actual arrangements. The patterns of government decentralization in OECD countries are diverse. Most local governments in Europe actually perform a major administrative role, in effect acting as agents for the central government. While this is justified by the advantages that local governments have over central governments in terms of information and control by voters, such arrangements require large financial resources, and more control by central government than where local governments simply provide local public goods. A drawback is the potential for conflict between different tiers of government. The trend towards more decentralization, common to most countries, has had to be met by more taxation or more grants. The need for revenue has encouraged a move away from property taxes to broader-based local taxes. Tax-sharing arrangements have often been under-rated, but in practice they compare favourably with complex and discretionary systems of transfers between levels of government.
Control system design is considered for attitude control and vibration suppression of flexible space structures. The problem addressed is that of controlling both the zero-frequency rigid-body modes and the elastic modes. Model-based compensators, which employ observers tuned to the plant parameters, are first investigated. Such compensators are shown to generally exhibit high sensitivity to the knowledge of the parameters, especially the elastic mode frequencies. To overcome this problem a class of dynamic dissipative compensators is next proposed, which robustly stabilize the plant in the presence of unmodeled dynamics and parametric uncertainties. An analytical proof of robust stability is given, and a method of implementing the controller as a strictly proper compensator is given. Methods of designing such controllers to obtain optimal performance and robust stability are presented. Numerical and experimental results of application of the methods are presented, which indicate that dynamic dissipative controllers can simultaneously provide excellent performance and robustness.
To contain the escalating cost of health care, a prospective payment system is being introduced into the military. The authors propose a proactive approach to this change in health care financing by evaluating the experiences of nurses to a similar change in the civilian sector. These approaches are presented as nine interrelated lessons: responding optimistically; shifting into a business mode; valuing clinical nursing experts; understanding the implications for documentation; moving to decentralized management; changing outpatient care delivery; considering the effects on job satisfaction; evaluating the relationship between costs and nursing resource consumption; and basing nursing practice in science.
