Decentralization policies are at the heart of education reform efforts in many countries internationally. Two important types of policies are those that: (a) remove barriers to private education; and (b) devolve authority and responsibility for schools from central level administrations to intermediate level organizations and ultimately to schools, relying more on local communities for financing, with an overall goal of improving effectiveness. While both types of policies are largely uninformed by empirical evidence regarding their impact on such education outcomes as student learning, in developing countries the evidence regarding the effects of local control is much weaker than that regarding private schools. This paper extends the literature on the impact of private education on achievement, while providing the first evidence on the impact of local control on achievement in a developing county. It analyzes data from 214 secondary schools in the Philippines to answer questions regarding: (a) the relative effectiveness of local, government and private secondary schools; and (b) the factors that account for observed differences.
Abstract In modern cryptologic theory, the design of cryptographic protocols is often based on the assumed difficulty of number theoretic problems. Especially, in order to prove the security of a cryptographic protocol based upon the assumed difficulty of a problem, a very important role is played by the legitimacy (as concerns the security of the cryptographic protocol) of that cryptographic assumption. Recently, Kurosawa, Ogata, and Tsujii proposed a new cryptographic assumption, the Chosen Discrete Logarithm Assumption (CDLA), and showed that any language in NP has a fourâmove, zeroâknowledge interactive proof (ZKIP) under the CDLA. In this paper, we define the modified CDLA and consider its legitimacy. Our principal result (that the modified CDLA is not a legitimate cryptographic assumption) follows from a theoretical analysis of expected polynomialâtime algorithms and the concrete construction of an algorithm based on the Artin conjecture.
Participatory development activities at local level in a sub-district located in the Central Plain of Thailand were studied employing the theoretical concept of the "linking loops" to analyze the related interactions among target group members and between the local level and superordinated organizations.The participatory development planning approach was first introduced in Thailand through her Fourth National Economic and Social Development Plan (1977-1981) as a strategy to apply the bottom-up concept.The qualitative, in-depth study covers nine projects at different stages of the planned development process alternatively covering the stages of initiation, implementation and completion. Despite the variety of projects involving different groups of the local population within the three case study villages in close vicinity, all these are set in the same socio-cultural context which allows direct comparison.Drawing on selected theoretical sociological explanations of the dimensions and determinants of people's participation, the conceptual and analytical framework is focussed on an actor-oriented approach using the theoretical concept of the "linking loops" to explicate the complex dynamics evolving in Thai rural society when engaged in local-level planning.By their mechanism of initiation, as explained in terms of the "linking loops" concept, three categories of projects are distinguished including village initiated projects (VIP) and government initiated projects (GIP) as well as projects initiated by villagers with a view to securing government support (V/GP). The comparison of hypothesis test results by project category leads to their classification as explanations of narrow range pertaining to one project category only, of medium range covering two out of the three categories, or of wide range rendering explanations valid for all three project categories.Six general hypotheses and their sub-hypotheses addressing as many stages of the project cycle are tested. The results of hypothesis testing vary by project category as summarized hereunder.VIP were effective owing to people's involvement in setting the project objectives, despite differences and conflicts; utilization of local knowledge in data collection and analysis; broad formal consensus on project design; active involvement in project approval; active involvement in implementation; and involvement in project evaluation through participatory monitoring and evaluation.V/GP differ substantially because the test results show that local-level projects initiated by villagers and obtaining resources from on-going government programmes were of limited effectiveness. The constraints include lack of people's involvement in the formulation of objectives, thus reinforcing dissent and conflict; differences in perception between local people and government agents with regard to data collection and analysis; lack of people's involvement and formal consensus on project design; lack of local interest in project approval due to complicated procedure followed by several government organizations involved; lack of people's participation in on- going project implementation due to changed circumstances and reassessment of the erstwhile situation; and lack of involvement in project evaluation, in the absence of participatory monitoring and evaluation.GIP implemented at local-level were found ineffective as a consequence of lack of local people's involvement in the specification of objectives and formulation of projects, aggravated by conflicting priorities among local people; differences in perception between local people and government agents regarding data collection and analysis; limited extent of people's participation in designing activities and weak consensus; lack of interest among local people not involved in project approval; discontinuation of people's participation in on-going implementation due to new perception after reassessment of the erstwhile situation, poor organizational set-up by the implementing agency, disagreement between local people and government agent, and conflict among local people; and lack of people's involvement in project evaluation, in the absence of participatory monitoring and evaluation.Overall, it is concluded that local-level plans are, indeed, of interest to local people. They tend to become ineffective, however, at any of the various stages of the planned development process, if people's participation is lacking in the formulation of project objectives, complicated by differing and conflicting objectives among local people; if differences in perception prevail between local people and government agents with regard to data collection and analysis; if deficiencies in project design are aggravated by the exclusion of local people from endorsing projects and procedure is complicated engaging several government organizations at the approval stage; if discontinuation of people's participation jeopardizes on-going implementation; and if project performance and outcome are assessed without participatory monitoring and evaluation.Recognizing certain existing deficiencies with a view to people's participation in the planned development process of local-level projects, policy recommendations are made focussing on suitability, design and intervention, taking into account local socio-economic, cultural and political factors. Moreover, the necessity of decentralization is stressed so as to strengthen people's participation in the planned development process. This means that wholesome delegation of responsibility in terms of decision-making power and budget allocation as well as finance control to the local level of development administration is essential to facilitate and foster participatory planning.
The aim of this report is to discuss appropriate planning philosophy for road development. The paper analyses the fundamental economic characteristic of road and transport service supply and demand. Two alternatives are considered: (1) that the citizens, in the political process, should be able to choose the main direction of the development of the structure of society including the transport infrastructure, and (2) that decentralized decision-making should be encouraged and facilitated by clear economic principles of pricing as well as investment criteria.
Postmodernism is beginning to enter organization studies. After introducing the contours of the debate, some of the early contributions are critically reviewed and then subjected to sympathetic scrutiny. A distinction between the periodization 'post-modern' and a 'postmodern' epistemology is explored in terms of its conse quences for writing about organizations. Each position is shown to have diffi culties attached to it and the political ramifications of these are explored. Some tentative suggestions are made to explain the rising popularity of the 'post' within organizational writing.
The paper presents a more efficient noninteractive zero knowledge proof system (NIZK) for 3 colorability. The length of the proof is 1/3 and the length of the reference string is 1/4 of those of Blum et al. (1988) respectively. The proposed NIZK is based on the quadratic residuosity assumption.>
The final tensile fracture of any composite structure is primarily due to the failure of its constituents, namely fibers and matrix in the present case. To date, no experimental data exists, to the authorâs knowledge, to define the behavior of constitutive fibers of a composite structure throughout its life span. The prime candidate for a fiber-based investigation is unidirectional zero-degree composite coupons. But unidirectional coupons do not demonstrate any significant loss of stiffness during fatigue cycling compared to other lay-ups. Even if stiffness degradation was significant, due to the nature of damage in this material system it would be impossible, practically, to monitor that change using conventional techniques (e.g. an extensometer) because the damage and failure process destroys the integrity of the contact between those devices and the material, under cyclic conditions. This investigation presents the findings of a fiber-based investigation of unidirectional composite material systems. In particular, a unidirectional graphite/epoxy system was studied, and the influence of applied load level on fiber fractures, and their influence on damage growth documented. A damage monitoring technique (patent pending) was developed to accurately record the state of damage in this material system without the usage of extensometers or strain gages. Following this method, two new damage norms were introduced, namely, âpercent phase damageâ and âpercent gain damageâ. Fiber fracture, strength degradation, and the life of unidirectional specimens were investigated and recorded as a function of various load levels. Fiber fracture, in general, showed no definitive growth pattern during fatigue cycling. It appears that the majority of the broken fibers that occur over nearly 90% of the life are due to the initial applied load cycle. This is one of the key findings of this investigation. âProof testingâ which is a common practice in industry for âverifyingâ the integrity of a structure, could very well be causing significant subsequent reductions in life. With these findings as a base, it is now possible to postulate the first well-founded mechanistic model of fiber-dominated fatigue degradation under tensile loading.
Over successive fiveâyear development plans, Indonesia has channeled large sums of foreign loans and domestic funds into water supply projects with the aim of providing clean water for a majority of households. Most projects have been planned and financed through the central government's public works ministry, though a growing share of rural water projects are being funded through earmarked grants provided to local governments. This paper examines how these central government transfers, in the aggregate, have responded to various indicators of expenditure needs. Overall, past allocations have matched existing demand and supply levels closelyâfunding has generally favored provinces with large populations, large numbers of water enterprises, extensive distribution networks in place, and high production capacity. They have not, however, worked in favor of either equalization or economic productivity objectives, as reflected by per capita income or GRDP growth rates. This analysis suggests that equity would be promoted either by including incomeârelated factors in future block grant allocation formulas or by shifting funding emphasis in the water supply sector from grantsâinâkind controlled by the central government to sectoral grants controlled mainly at the local level. Such policy reforms would also further promote the nation's professed goal of decentralizing infrastructure development.
Ten years after the decentralization laws were adopted by the French Parliament, the once-and-for-all effects of the changes introduced have had time to work themselves out and the observed evolutions can safely be assumed to reflect the permanent functioning of the French system of local goverments in their new institutional environment. The present paper reviews some of the major consequences of the reforms, mostly on local public finance. It stresses the potential dangers of a system in which, due to the disproportionate share of some taxes and to the important role of central government in financing, locally elected authorities may well not be «accountable» enough. In addition, the equalization properties of existing inter-governmental grants seem much too limited compared to the tendencies, inherent in the current system of local finance, to strong polarization of economic development and to geographic segregation of population according to income levels.
This article presents a conceptual framework for analyzing societal responses to women battering in Israel. The model of policy analysis consisted of three specific dimensions namely: 1) descriptive-operational; 2) analytic interpretive; and 3) chronological. Allocation provision delivery and financing of interventions with the abused Israeli women and their families were conducted from 1986 to 1988 through telephone surveys. Data indicate that due to strong religious influences on family life and political factors poor services were provided to abused women. The influence of social welfare in response to women battering were as follows: 1) intervention in woman battering was specific rather than universal; 2) services have been decentralized since their inception; and 3) intervention has been influenced by a collectivist residential orientation to welfare services. Furthermore government agencies and nongovernmental agencies provide only limited services for physically abused women.
With almost 27% of land in Costa Rica protected to some extent the country is at the forefront of national conservation efforts. National parks and biological reserves constitute fully 12% of the country. Efforts began in 1969 to create parks and protected areas. Lands were expropriated and preserved accordingly over the next decade. State financial resources were scarce however and many landowners were forced to wait years before receiving full compensation for lands expropriated through these government initiatives. Economic conditions worsened in the first half of the 1980s impacting adversely upon protected areas. Populations in buffer zones encroached and protected areas were left to deteriorate. The conservation environment grew green however following the election of President Oscar Arias in 1986. His administration consolidated conservation efforts and made institutional reforms. President Arias met the multiple challenges of slowing the nationwide deforestation rate improving park management and providing survival alternatives to populations in buffer areas in the following manner; he consolidated conservation power under one ministry; developed a decentralized system to link and manage protected and buffer areas; created new financing mechanisms; and developed technical capacity to describe and catalog species and their potential uses in Costa Rica. If Costa Rica realizes its objectives as set forth in its National Conservation Strategy almost 95% of the flora and fauna in the country will be preserved. These represent 5% of all plant and animal species known to exist. Costa Ricas experience demonstrates how sustainable development requires creativity innovation and a capacity to implement new programs and policies. Other countries might call upon lessons learned in Costa Rica as they develop their respective institutional structures for conservation and link conservation and development across national regional and local levels.
This article examines the mechanics and attributes of concerted debt reduction agreements that offer creditors a choice between exit and relending options. The menu approach sets prices for different choices that implement a decentralized equilibrium. When banks can commit to choose from the menu and are not allowed to free ride, a menu can be designed that assures that the price paid for debt repurchased is equal to the marginal value of the debt claims. This can be achieved by taxing the gains that accrue to nonexiters with a request for new money. The equilibrium amount of debt reduction rises when the new money request is increased. The importance of banks' heterogeneity for menus to dominate simple concerted buybacks and the case in which debt reduction can be financed by loans from international financial institutions are discussed.
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.
