Against the backdrop of the financial and economic crisis, federal and regional States are engaging in several reforms. The financial constitutional design and institutional setting in the area of fiscal and financial matters are being revised in order to better adapt to the current challenges, which result both from the supranational sphere of economic governance and the domestic one. The rationale behind these reforming processes lies in the struggle between the apparent needs to re-centralize while accommodating decentralization claims. The paper focuses on federal and highly regionalized European States by adopting a comparative domestic perspective and investigates reform processes in the area of fiscal matters and financial intergovernmental relations. It explores the most significant features that permeate the various legal orders, trying to single out the different trends in shifting powers in favour of either (re)centralization or decentralization. To this extent the recognition of autonomy on the revenue side and the accommodation of autonomy and solidarity within the new fiscal regimes will be analyzed. Moreover,intergovernmental cooperation in fiscal and financial areas will be scrutinized trying to point out crucial characteristics from a comparative perspective. To this regard particular attention will be given to major recently established bodies and procedures in the fiscal and public finance area as well as to their role within domestic economic governance.
This book is based upon research and reflection supported by BALTA during its initial research program from 2006-2012. It explored many of the themes that became central to BALTA’s work in its Scaling Innovation for Sustainability Project. With our communities confronted by major sustainability challenges, many linked to the impact of climate change, it argues for replacing the paradigm of limitless economic growth with a more decentralized, co-operative, steady-state economy. It examines case studies of success in energy sufficiency, local food systems, low-cost community based financing, affordable housing and land reform. Specific chapters and the book as a whole redefine the development paradigm within a sustainability and steady-state economic framework.
One important aspect of fiscal decentralization policy is delegation of authority and responsibility of management of public finance to regional governments, especially those of municipalities/districts. After more than ten years of implementation, it is now the right time to evaluate the policy questioning how effective its impacts on regional economic development. The study intends to find on how effective the performance of regional public finance is in providing basic infrastructures and how effective the provision of basic infrastructures reduces the poverty rates. By using panel data methods, this study confirms the positive relationship between performance of regional finance management and provision of basic infrastructures (especially those of road and electricity, but not that of drinking water). On the other hand, the relationship between the provision of basic infrastructures and poverty rates, as expected, is negative. This finding strengthens the belief that it is necessary to further enhance the basic infrastructures development to reduce poverty rates.
Climate change—fears of it; predictions about it; proposed reactions to it; and in some cases, denials of it—is a momentous issue for humanity, and it promises to become even more important. However, despite its importance—and mountains of scientific research on the topic—real progress by those with the means to address climate change has been slow in coming. The warming climate, with its accompanying intense weather, rising seas, and wrenching changes in agriculture, human health, and ecosystems in general, is not a recent discovery. Scientists and policymakers have been talking about it for decades. Climate scientists have produced reams of information about the change that is upon us—some showing that the shift is well under way, some offering ideas about how to cope with it by mitigating its effects or by adapting to it. Scientists are starting to develop the tools necessary to discover links between global change and specific local events, such as floods and droughts. Much of the US-based research is directed at people who make political decisions: members of Congress, the president, state legislators, municipal officials. But whereas the flow of information from scientists has been copious, the response from policymakers, including those at the topmost positions in government, has been minuscule. Interest in preparing for climate change seems to have been superseded by concerns about the economy. But the problems of a changed climate march on (see National Research Council definitions box), and at some point, policymakers will have to deal with them. As far back as 1978, Congress passed the National Climate Program Act in response to a need “to assist in the understanding and response to natural and man-induced climate processes and their implications.” The legislation stated that “Congress finds and declares” that “an ability to anticipate natural and man-induced changes in climate would contribute to the soundness of policy decisions in the public and private sectors,” and that “the United States lacks a well-defined and coordinated program in climate-related research, monitoring, assessment of effects, and information utilization.” Today, after dozens of data-heavy reports on climate change, bolstered by the work of the Intergovernmental Panel on Climate Change (IPCC), the crisis remains unaddressed, in large part because the issue has become a partisan arguing point—increasingly so as a presidential election looms. In April 2011, the House of Representatives considered action stating that “Congress accepts the scientific findings… that climate change is occurring, is caused largely by human activities, and poses significant risks for public health and welfare.” The national legislators voted the proposition down 240 to 184, largely along party lines. Scientists who study climate change, then, are left with the following question: How do we communicate in a meaningful way with policymakers? Climate change, in the United States and elsewhere, covers most areas of the human experience. A report from the US National Research Council lists the following areas of concern: changes in the climate system; sea-level rise and its effects on the coastal environment; freshwater resources; ecosystems, ecosystem services, and biodiversity; agriculture and aquaculture; public health; cities and the “built environment”; transportation systems; energy systems; solar radiation management; national and human security; and climate policy. First of all, says Pamela A. Matson, an interdisciplinary earth scientist at Stanford University, scientists should not tell policymakers what to do. Matson chaired one of four expert panels charged by the US National Academies in 2009 with studying climate change and recommending responses to it. The panels—Limiting the Magnitude of Future Climate Change, Adapting to the Impacts of Climate Change, Informing an Effective Response to Climate Change, and Advancing the Science of Climate Change—each produced extensive reports. Together, these reports and a summary volume form a solid tutorial on the challenges facing the nation (see For more information). Matson headed the Advancing the Science of Climate Change panel. “We can't do much about politics,” said Matson in an interview, “other than to keep reminding people that there is a huge amount of evidence about climate change, its causes, and the risks associated with it. Decisionmakers of all sorts will need to decide if they want to take the risks and expose future generations to even greater risks, but scientists can do our best to provide the best and most clear information about those risks and uncertainties. We can also help by providing viable options for reducing those risks—options that make sense from social, economic, technical, and environmental perspectives. The Advancing report calls for more research designed to develop such options and thus support decisionmakers who want to respond to the risks of climate change by limiting it and adapting to it.” In practically all of the heavyweight studies of climate change, including those in the National Academies quartet, the panelists assumed that the federal government is the logical leader in climate policymaking, if only because climate does not respect local boundaries (or international ones either). But there are scant signs of leadership from federal officials, and there is active opposition to any climate action (or even the notion that climate change exists) among some national legislators. Progress at the federal level, says Peter Raven, cochair of the National Academies panel Informing Decisions and Actions, is missing. His panel recommended that the federal government create “comprehensive, robust, and credible information systems to inform climate choices and evaluate their effectiveness.” “My impression,” said Raven recently, “is that it hasn't happened. The United States is the only nation in the world where serious doubt is expressed about the scientific conclusion that the climate is warming rapidly and that human beings are the principal underlying factor. That kind of anti-intellectualism can only hurt as we try to maintain our standing in science and technology against some very stiff competition internationally.” Robert Fri, visiting scholar at Resources for the Future, chaired the Limiting the Magnitude of Future Climate Change panel, which recommended “a framework of national goals and policies” to limit greenhouse gases. Asked about the report's reception, he replied, “Policy attention has been focused on the economy recently. Not much has happened on the climate front as a result.” So the search for leadership has turned elsewhere—to local, state, and regional governments and private organizations. Several states have undertaken serious studies of climate change problems, many of them as a result of gubernatorial executive orders issued a few years ago, when climate change was considered less controversial. Some went a step further and set up commissions to recommend legislative action. The results of those efforts have been mixed; the economic crisis has sapped much of the climate change energy of local, as well as national, politicians. Arizona's Policy on Climate Change, instituted on 2 February 2010, under Governor Jan Brewer, seeks to reduce greenhouse gas emissions “while maintaining Arizona's economic growth and competitiveness.” Yet in the same executive order that established the policy, Brewer pulled her state out of a promising regional effort, the Western Climate Initiative, to limit the gases. The 15-member commission created by Brewer's executive order included representatives of electric power, manufacturing, and mining companies, but no scientists.

For a critical look at America's willingness to adapt to climate change, see Robert Repetto's 2008 report for the Yale School of Forestry and Environmental Studies at http://environment.yale.edu/publication-series/climate_change/5790. The Colorado Climate Project created a blue-ribbon action panel in 2007 that, a year later, produced 70 recommendations for reducing greenhouse gas emissions and preparing for the coming changes. The panel's efforts appear to have been received favorably by policymakers. Texas, beset by wildfires in 2011 that some experts linked to climate change, has no state adaptation plan, according to a survey by the Pew Center on Global Climate Change. Texas leads the states in carbon dioxide emissions. In Connecticut, the Governor's Steering Committee on Climate Change says that it is “working with stakeholders” and “assessing the impacts of climate change.” However, the committee's Web site devotes approximately half of its space to thanking the company that designed its logo. Massachusetts has made a more strenuous effort. In September 2011, the state sent a report to its legislature in which the expected impacts were analyzed and suggestions were made for reactions to them. The proof of the pudding in Massachusetts, as in the nation as a whole, lies in what happens after the recommendations go to the policymakers. In the Bay State, that would include the office of Frank I. Smizik, the chair of the House Committee on Climate Change. Smizik believes that climate change is going to affect “every corner of our lives,” is already creating problems, and is “one of the most complex and interrelated problems we face. And that makes it even more of a challenge to confront.” In an interview, the legislator praised the state's framework report both for its “long-term and far-reaching strategies” and for the “small, incremental improvements we can make at little or no cost. This aspect of the report makes the necessary task of climate adaptation seem more feasible.” Does this mean that Massachusetts's policymakers will rush to enact laws to deal with the well-documented menace? “Ideally, the need to adapt to climate change will be taken seriously, and these strategies will be swiftly transformed into reality in Massachusetts,” said Smizik. “Realistically, it won't be that easy. My job as the Chair of the House Committee on Global Warming and Climate Change is to advocate for the strategies that I think are not only most effective but also the most politically feasible at this time. I could see some of the more short-term, cost-effective strategies making progress in the State House as legislative packages. Meanwhile, some strategies will be directly implemented by state agencies. “I feel these issues are very pressing and they warrant our immediate attention. But… the legislating and governing process takes time, with good reason. The release of this adaptation report is an important step for our state, but it's hard to say how quickly or slowly these adaptation measures will become law. The economic climate is such that legislators are very focused on job creation and the like, and environmental issues are often pushed to the back burner in this situation.” The state of Washington is another place where policymakers take climate change seriously. Hedia Adelsman is the director of the state's Department of Ecology. Her predecessor in that job was Christine Gregoire, who went on to become the state's attorney general and then governor. Adelsman credits Gregoire with helping move climate awareness into action. Also, the University of Washington produced an exhaustive examination of climate change and ways to react to it that has served as a vital resource for legislators and other policymakers. Within 50–100 years, 2400 miles of major roadway are projected to be inundated by sea-level rise in the Gulf Coast region. The map shows roadways at risk in the event of a sea-level rise of about 4 feet, which is within the range of projections for this region in this century under medium- and high-emissions scenarios. In total, 24 percent of interstate highway miles and 28 percent of secondary road miles in the Gulf Coast region are at elevations below 4 feet. Source: US Global Change Research Program (www.globalchange.gov). Even though Washington is more environmentally conscious than most other states, economic troubles have hampered action on the climate front. “The conversation is not as active as it used to be,” said Adelsman in an interview, “[for] a couple of reasons: One of them—no surprise—is all the budget problems that the state is facing. And when you talk about the impact of climate change, people really see it as in the future. And right now we have all these urgent problems facing us. Some of the impacts that would be due to climate change… people don't see as something that's happening now. They see it as happening a little bit more in the future. So they feel like they can get back to it later… But the communication continues. “It all depends on how you describe it,” she said. “If you are describing the problem as a water-availability issue—if we are going to face a major issue with water available for irrigation; for municipal, for our fish, the salmon—you get people to listen. If you talk about it as global warming, it's immediately, ‘go away.’ “It's kind of sad to not call it by what it is, but it's much easier to communicate with the public and with the policymaker if you put it in these terms.” Some, including the authors of the National Research Council's panel Advancing the Science of Climate Change, think that a likely source of federal leadership can come, with a few modifications, from an existing organization: the US Global Change Research Program (USGCRP), which was created in 1989 as a presidential initiative by George H. W. Bush. USGCRP coordinates and integrates the global change work of 13 agencies, from the US Department of Agriculture to the US Department of Defense to the US Environmental Protection Agency and the Smithsonian Institution. Thomas Armstrong, of the White House Office of Science and Technology Policy, is USGCRP's executive director. In an interview, he said that he certainly agreed with the panels' findings. “But the real challenge comes not when you recommend strategic changes but when you get down to the nuts and bolts of implementing programs.” One potential obstacle, he said, could come if 13 agencies, which together receive $2.8 billion in global change research funds, are asked not only to funnel their work through a single office—his—but are made to redirect their agencies' funding as well. “If we were to take this level of enterprise and now say that it is no longer just coordinated but actually run out of my office, with all the resources coming to my office, that would be a big change in our collective way of doing to say the said is the 13 agencies, and the 13 are The of 13 them and a of leadership of this I would be that in their we would be the and of 13 federal who their research and to 13 agencies' In we would be the USGCRP out of what makes this program so the Science in climate information to policymakers. one is the climate change who can of all science in the of some is the of of scientific which scientists by their as does the in of such as very out of out of very than out of and so deal with communication such as these and many there has a of or for a can be government agencies, such as the that produced the state action or state such as Hedia in and federal such as the USGCRP they can be such as the regional Climate Science that were established in 2009 by the US Department of the The are by the US and by one or more significant of communication is by private and the Pew Center on Global Climate Change, which has been to and information on climate Climate an of and a for natural systems in the face of climate change.” The which a large of for for adaptation, dozens of studies from The appear to be some in scientific information into the of those who already want to it in their program director at the Climate for the part of a regional program run by the National and says that it that are more with decisionmakers much to the in of decisions that may be to scientific for something more to We certainly people who are out scientific information to make decisions that help them deal with of these decisions to the that has the region for years and are vital to policymakers who deal with water does a of its when public and private including a to a are also for scientific about adaptation and a then, is on the that climate change is important. are who for one or climate or climate change as something they really need to more about into their it's because a to attention to of the US Department of the have been under orders now to make climate change part of their it's because an like their is to the impacts of climate, and they want to more so they can to address this it's because an or government has a climate impact that them into The is an of as is in the United States and for how are projected to become more A so that it is years would other year or more by the of the century under the Source: US Global Change Research Program (www.globalchange.gov).

Fordism-Keynesianism gradually transited to neoliberalism during 1970s economic recession in capitalist society, shifting urban governance from managerialism to entrepreneurialism. At the same time, China’s 1978 political-economic reform has led to a rapid development and a profound urban transformation characterized by globalization, neo-liberal decentralization and marketization over the past thirty years. To sustain the development and further promote the transformation, mega-events as one of those entrepreneurial policy programs are increasingly favored and widely used by city policy makers. Adopting urban entrepreneurialism as the theoretical perspective, this research explores mega-events, aiming to resolve two debates concerning urban entrepreneurialism and mega-events in the context of China: whether mega-events are effective and sustainable ways for China’s urban development in entrepreneurial city discourses and whether Chinese cities and their local states are entrepreneurial in nature in mega-events? It then takes Shanghai Expo 2010 as the case, focusing on how the Expo as entrepreneurial city action impacts on Shanghai’s urban transformation and how different stakeholders behave in the Expo development. Analysis of the case provides some findings resolving the debates. \n \nFirst, through landscape reconfiguration, spatial restructuring and new sources provision, Expo 2010 effectively transforms Shanghai city within a short time, showing entrepreneurial city qualities in diminutive spatial scale. However, it fails to improve social life except those who under high media exposure and is powerless to impress the world as China has little voice in the Western mainstream media. Moreover, while Expo 2010 generally benefits sustainable development by using energy saving technologies in Expo Park, by creating “Shanghai Mode” rehabilitation for affected communities and by preserving industrial and cultural heritage for future creative industry development, it still negatively impacts general urban living and causes exorbitant investment. \n \nThen, entrepreneurial governance is manifested in Expo operation as municipal government unites various stakeholders to ensure the smooth progress of the event, a process explicable by both urban regime and growth machine models. The private sectors are encouraged by municipal government to join Expo market as sponsors or developers and are mobilized interests triggered by Expo opportunities. Civil communities play auxiliary roles that must be united by government to achieve long-term growth. Urban planners are important inter-mediators among stakeholders in Expo, serving municipal government for urban growth. Although “Local Developmental State” model exhibits at municipal level as “development” represents the primary legitimizing principle of the state above those of individuals and the plan-rationality suppresses the market rationality, the “Entrepreneurial State” model can better interpret the nature of government in terms of coordination and partnership in Expo 2010. The government start-ups commercially operate in financing, investment attraction and land development, actively cooperating with private, foreign capitals and other social forces. \n \nThese findings imply that the event-led restructuring is overall effective for the transformation of urban order from traditional industries to flexible leisure consumption, from monocentric city to polycentric mega-city region, consistent with the tide of postmodern city. They also imply that the operation of Expo by municipal government is entrepreneurial in nature, corresponding to the emerging neo-liberalization with Chinese characteristics.
Polish Abstract: Rozwoj edukacji jest jednym z priorytetow polityki Unii Europejskiej od początkow jej istnienia. W ciągu ostatnich 15 lat szczegolny nacisk kladziony jest na modernizacje szkolnictwa wyzszego, ktore postrzegane jest jako kluczowe dla rozwoju zarowno calej Unii Europejskiej, poszczegolnych panstw czlonkowskich, jak i indywidualnych obywateli. Postulowane reformy wymagają zmian w obszarze zarządzania, jak i finansowania uczelni, a w szczegolności odejścia od scentralizowanego finansowania zorientowanego na zasoby w kierunku zdecentralizowanego finansowania zorientowanego na wyniki. Transformacja ta powoduje koniecznośc mierzenia efektywności i skuteczności szkolnictwa wyzszego w roznych jego aspektach, w tym rowniez w obszarze edukacji. Artykul koncentruje sie na badaniu mozliwości zastosowania modelu J. Mincera do mierzenia wplywu wyzszego wyksztalcenia na poziom wynagrodzen i wyznaczania tzw. prywatnej stopy zwrotu z inwestycji w edukacje. Badania empiryczne przeprowadzone są na danych pochodzących z niemieckiego badania panelowego SOEP.English Abstract: The development of educational system has been one of the priorities of European Union policy since the beginning of its existence. In the course of the last 15 years particularly strong emphasis has been placed on modernization of higher education, which is perceived as key factor for development of European Union, each member state separately, as well as individual EU citizens. The postulated reforms require changes both in the area of governance and funding of the universities, in particular a shift form centralized input oriented funding mechanisms towards decentralized outcome oriented financing is needed. This transformation causes necessity for measurement of efficiency and effectiveness of various aspects of higher universities activities, including education area. The paper focuses on application of Mincer model in analysis of higher education influence on the level of wages in order to determine the private rate of return to education. Empirical research have been conducted using the data from German Socio-Economic Panel Study (SOEP).
What is the legal status of a “bitcoin,” a decentralized peer-to-peer digital currency? Is the use of bitcoins even legal? Should it be? The bitcoin cybercurrency thus poses a puzzle. Unlike centralized and publicly-created metallic or paper currencies, bitcoin is a privately-created, decentralized medium of exchange and thus is not backed by any national or transnational government or by any public or private bank. As such, the legal status of the bitcoin cybercurrency is murky and unclear at best. Despite this legal uncertainty, the demand for bitcoins on the Internet continues to grow. The authors will present a legal, normative, and game-theoretic analysis of the bitcoin cybercurrency. To provide a theoretical background to our legal and normative analysis, the first part of the paper will present an analytical model of the behavior of bitcoin users. In summary, the use of bitcoins can be modeled as a Prisoner’s Dilemma. That is, because of the limited supply of bitcoins and the rising demand of this cybercurrency, the temptation to defect by hoarding this currency -- rather than using bitcoins for the exchange of goods and services -- threatens the stability of the bitcoin cybercurrency as a whole. In the second part of the paper, the authors consider the legal status of bitcoins, discuss the policy and normative arguments for and against the legalization of bitcoins, and propose several possible legal frameworks for protecting the bitcoin cybercurrency and solving the bitcoin puzzle.
Eurasian cities, unique in the global \n spatial landscape, were part of the world's largest \n experiment in urban development. The challenges they now \n face because of their history offer valuable lessons to \n urban planners and policy makers across the world from \n places that are still urbanizing to those already urbanized. \n More than three-quarters of the built environment in \n Eurasian cities was developed after 1945 in a centralized \n fashion. Central planners could implement whatever they \n considered good practice planning solutions, and \n Eurasia's cities became their drawing boards. The \n central planners got a lot right easy access to public \n transportation, district heating networks, almost universal \n access to water systems, and socially integrated \n neighborhoods. At the same time, they failed to acknowledge \n the importance of markets and individual choice in shaping \n sustainable and congenial places for people to live in. From \n a spatial point of view, it became clear that many Eurasian \n cities were developed in places where they should not have \n been. To populate sparsely inhabited territory, Soviet \n planners pushed urban development toward the heart of \n Siberia. Many of the resulting cities had no rural \n hinterland to rely on for daily food needs and had to depend \n on subsidized goods and services. Many Eurasian cities face \n an overdeveloped public service infrastructure that is hard \n to maintain and upgrade. Facing an economic downturn in the \n 1990s and lacking experience in decentralized urban \n management, many local authorities struggled to run these \n services. Public transport ridership fell in most cities, \n with more people commuting in private vehicles. Recycling \n networks disappeared, and soaring consumption overwhelmed \n solid waste management systems. District heating systems \n became large energy sieves hard to run and maintain without \n subsidies. Plaguing water systems are large shares of \n nonrevenue water, and low tariffs do not ensure the cost \n recovery needed for upgrades and repairs. This book \n discusses all five of these issues rethinking, planning, \n connecting, greening, and financing in more detail. It seeks \n to analyze the key challenges created by central planning, \n outline how these challenges were addressed in the \n transition years, and identify some steps Eurasian cities \n should take to chart a sustainable development path for \n themselves. The book also shows how some of the most \n progressive cities in the region have been tackling these \n problems and, in doing so, shedding the last vestiges of the \n socialist economy.
利用Cha-Cheon 的基于身份的签名方案提出了一个可证安全的基于身份的可验证加密签名(verifiablyencrypted signature,简称VES)方案,并利用该方案和基于身份的代理可验证加密签名(proxy verifiably encryptedsignature,简称PVES)方案提出了一个新颖的多元合同签署协议.信息交换过程中,原始签名者或代理签名者分别利用VES 或PVES 实现承诺消息的交换与认证,并未使用复杂的零知识证明系统,从而有效避免了大量运算.当争议发生时,可信第三方从VES 或PVES 中恢复出有效的合同签名,以保证签署者的公平性.安全性分析结果表明,协议满足不可否认性、时效性以及公平性.;Utilizing the Cha-Cheon’s identity-based signature scheme, a provably secure identity-based verifiably encrypted signature (VES) scheme is proposed. Utilizing the proposed scheme and identity-based proxy verifiably encrypted signature (PVES) scheme, a novel multiplex contract signing protocol is also proposed. The original signer or proxy signer uses VES or PVES to realize the interaction and certification of the commitment message in the information exchange process. The proposed scheme does not need the zero-knowledge proof and excessive computation. An optimized trusted third party who participates in the protocol extracts the formal signature from the VES or PVES only when problem occurs. The performance analysis results show that the scheme satisfies non-repudiation, timeliness and fairness.
This paper analyses 26 time series that measure daily data for different attributes of the Bitcoin network and studies how the virtual currency behaves compared to a basket of currencies containing the Brazil Real (BRL), the Chinese Yuan (CNY), the Euro (EUR), and the Japan Yen (JPY) against the US Dollar (USD). \nBasic statistics about the time series have been taken and stationarity has been studied in order to build sterilized fact data and meaningful cointegrations have been found among them. By applying a Vector Autoregressive (VAR) model, a regression has been built among the currencies and the Granger causality test has been applied in order to determine whether one time series (of a given currency) is useful in forecasting another and to observe causal relationships among the currencies studied.
Built on the theories about talent competition between rent-seeking and entrepreneurship, and the theories about constitutional environment and rent-seeking, this dissertation explores empirically the effects of a country's constitutional settings on entrepreneurship, in terms of the quantity of entrepreneurs and the quality of their performance. Both the de facto and de jure constitutional environments are studied. In particular, with respect to the de facto constitutional environment, I considered the property rights protection, decentralization, and the factors suggested by the "selectorate theory". In relation to the de jure constitutional environment, I focused on six aspects including electoral rules, form of government, federalism, property rights protection, judicial independence and antidiscrimination provisions. Three indexes were constructed to measure the de jure property rights protection, judicial independence and antidiscrimination provisions, using the data set provided by the Comparative Constitution Project.The empirical study first shows that the quantity of entrepreneurs is inversely correlated with the quality of entrepreneurship in a country. If entrepreneurship does serve as the engine of economic growth, it is perhaps the quality, rather than quantity, that matters. This study then demonstrates that the de facto property rights protection is associated negatively with the quantity of entrepreneurs, but positively with the quality of entrepreneurship. The effects of the two key factors of the selectorate theory, the size of the winning coalition and the ratio of this size to the size of the selectorate, also appear to be compatible with what the theory is to predict. On the other hand, neither fiscal nor political decentralization is found to significantly affect entrepreneurship. Among the de jure constitutional features, two have significant influence on entrepreneurship. First, the constitutional design of judicial independence has a negative effect on the quantity of entrepreneurs, but a positive one on the quality of their performance. Second, majoritarian electoral rules, compared with non-majoritarian rules, have a negative effect on the quality of entrepreneurship. In contrast, the presumed effects of the other three formal constitutional attributes, federalism, presidentialism and property rights protection, cannot be ascertained.Apart from the cross-country study, I also conducted a detailed research on China. Entrepreneurship in China is a case of entrepreneurial development in an authoritarian state lack of secure property rights and the rule of law, hence afflicted with profuse rent-seeking activities. Under these circumstances, entrepreneurship hinges on both the rent-seeking and the entrepreneurial abilities. Drawing on the private enterprise surveys, I found that, in China, the politically connected were systematically advantaged in terms of bank finance, entry to regulated industries and judicial treatment, when they plunged into the business world. The Chinese case also indicates that, when entrepreneurs cannot trust the commitment made by the state in the constitution, they will be eager to scoop profits as soon as possible and exit swiftly with accumulated wealth.Finally, this dissertation concludes by suggesting that a healthy development of entrepreneurship should be sustainable rather than aiming merely at quick money and instant success. It should allow all talented people to reach their full potentials, rather than keep the politically disconnected away from resources needed to make the best use of their potentials. Above all, it wants a constitutional environment with reliable property rights and equal access to opportunities, neither of which is seen in today's China.

Abstract Regional autonomy and fiscal decentralization has the objective to create a regional self-reliance. Not all regions have the same readiness in creating independence. To overcome this problem, the central government balance fund / fund transfers to local governments. But the empirical evidence, some studies suggest the existence of the flypaper phenomenon of local government in Indonesia, with an indication of the dominant role of the transfer of funds to finance revenue expenditure in the region. This study uses a sample of 30 regions in Central Java are sourced from the Report of Actual Revenue and Expenditure Budget (budget) from 2009 to 2011. Sampling method using Purposive Sampling method. Research tool used is logistic regression. The results of this study Shopping Employees has a significant effect on flypaper. While the Local Government Investments and Local Government Debt Payments had no effect on flypaper.
Due to the ageing and the decreasing birth rate in Japanese society, an important problem of providing nursing care for the elderly has occurred. Therefore, it is strongly desired to develop a wearable actuator to use in nursing care or rehabilitation. The purpose of this study is to develop a high-power flexible actuator with a displacement sensor which can be used in supporting a bathing. In our previous study, we proposed and tested a rubber artificial muscle with the inner diameter sensor. The inner diameter sensor consists of two electric circuit boards with two photo reflectors. Two boards are bonded together to contract the inner diameter sensor. The sensor also has a doughnutshaped bulkhead to keep a seal. The sensor is inserted into the tube of the artificial muscle. The senor is set at the end of tube. This sensor can be expected to estimate the axial direction displacement of the rubber artificial muscle, because the relation between the inner diameter and the axial directional displacement of the muscle has a strong correlation. However, if the external bending force is applied to the end of the muscle, the inner diameter sensor cannot hold at the center position of the tube. Therefore, the sensor cannot measure the inner diameter exactly. In this study, the improvement of the inner diameter sensor was executed. The improved sensor has 4 photo reflectors on the two electric circuit boards to compensate the measuring error. The position control was also carried out by using the actuator with the built-in inner diameter sensor. As a result, the axial direction displacement of the muscle could be estimated well by the tested inner diameter sensor, and a relatively good position control performance was obtained.
The paper contains main concepts of the interactive proof theory and suggests zero-knowledge proof of Diffie–Hellman problem solution with bilinear maps.
The analysis of the administrative capacity of institutions in the regional development starts from the analysis of the existing framework for the implementation of regional politics in Romania and studies the extent to what the structures and competencies were regionally enlarged as to contribute in the regional development. The basic hypothesis considered for such analysis had in view the fact that the differences recorded with respect to the implementation capacity of the regional development policy are caused by the various levels of the administrative capacity of the national, regional and local institutions existent in Romania. Although the regional development activity is, both centrally and regionally, dominated by the Regional Operational Programmme 2007-2013 (ROP) implementation, significant activity also exists outside the ROP, but only regionally. The regional strategies incorporate to a great extent the strategic objectives established nationally, being coordinated with the national financing instruments for economic, social and territorial development. The undertaking degree of responsibilities regarding the objectives fulfillment of the regional development policy is relatively low both regionally and locally, and the main indicator which contributes in sustaining this conclusion is the absence of an adequate level regarding the property holding on certain strategies and also the methodological lack of strategies. Nationally, the current activity of Ministry of Regional Development and Tourism in the field of regional development totally overlaps the management activity of ROP. The management of structural funds 2007-2013 granted through ROP deals with various situations in which, due to the fact that the Law of regional development remained behind the legislation for the structural instruments implementation in Romania, additional resources are necessary to be granted in order to be found solutions through other types of regulations. The Romanian legal and institutional setting allowed a centralized top-down approach for the regional development process and brought forward the approach of the type â€Å"local development which falls among certain priorities of regional development established nationally†. Definitely, the local development is important for the regional development, but it is not self-sufficient in this respect. Therefore, the centralized approach should be completed by a decentralized approach, as a natural next phase.
Silicon as a mono-crystalline bulk semiconductor is today the predominant material in many integrated electronic and photovoltaic applications. This has not been the case in lighting technology, since due to its indirect bandgap nature bulk silicon is an inherently poor light emitter.With the discovery of efficient light emission from silicon nanostructures, great new interest arose and research in this area increased dramatically.However, despite more than two decades of research on silicon nanocrystals and nanowires, not all aspects of their light emission mechanisms and optical properties are well understood, yet.There is great potential for a range of applications, such as light conversion (phosphor substitute), emission (LEDs) and harvesting (solar cells), but for efficient implementation the underlying mechanisms have to be unveiled and understood.Investigation of single quantum emitters enable proper understanding and modeling of the nature and correlation of different optical, electrical and geometric properties.In large numbers, such sets of experiments ensure statistical significance. These two objectives can best be met when a large number of luminescing nanostructures are placed in a pattern that can easily be navigated with different measurement methods.This thesis presents a method for the (optional) simultaneous fabrication of luminescent zero- and one-dimensional silicon nanostructuresand deals with their structural and optical characterization.Nanometer-sized silicon walls are defined by electron beam lithography and plasma etching. Subsequent oxidation in the self-limiting regime reduces the size of the silicon core unevenly and passivates it with a thermal oxide layer.Depending on the oxidation time, nanowires, quantum dots or a mixture of both types of structures can be created.While electron microscopy yields structural information, different photoluminescence measurements, such as time-integrated and time-resolved imaging, spectral imaging, lifetime measurements and absorption and emission polarization measurements, are used to gain knowledge about optical properties and light emission mechanisms in single silicon nanocrystals.The fabrication method used in this thesis yields a large number of spatially separated luminescing quantum dots randomly distributed along a line, or a slightly smaller number that can be placed at well-defined coordinates. Single dot measurements can be performed even with an optical microscope and the pattern, in which the nanostructures are arranged, enables the experimenter to easily find the same individual dot in different measurements.Spectral measurements on the single dot level reveal information about processes that are involved in the photoluminescence of silicon nanoparticles and yield proof for the atomic-like quantized nature of energy levels in the conduction and valence band, as evidenced by narrow luminescence lines (~500 µeV) at low temperature. Analysis of the blinking sheds light on the charging mechanisms of oxide-capped Si-QDs and, by exposing exponential on- and off-time distributions instead of the frequently observed power law distributions, argues in favor of the absence of statistical aging. Experiments probing the emission intensity as a function of excitation power suggest that saturation is not achieved. Both absorption and emission of silicon nanocrystals contained in a one-dimensional silicon dioxide matrix are polarized to a high degree. Many of the results obtained in this work seem to strengthen the arguments that oxide-capped silicon quantum dots have universal properties, independently of the fabrication method, and that the greatest differences between individual nanocrystals are indeed caused by individual factors like local environment, shape and size (among others).
Independent regulatory bodies are important economic institutes, which take on a part of classical state affairs, which generally need particular, i.e. specialized knowledge, which does not exist in state management. European countries have different experiences when it comes to bearers of public authorization, representing intermediaries between the state on one hand, and companies and citizens on the other. In those countries with a traditionally big state apparatus, there are few agencies and vice versa, where there is a large portion of state affairs decentralized, small governments, supported by a modest central state apparatus are established. In the countries of Central and Eastern Europe, along with the process of transition, there occurred the process of "agencification". Serbia is maybe the worst example, with large coalition governments, which have established almost 200 different independent institutions. The causes of independent public body boom in Serbia are to be sought in a too liberal understanding of laws regulating this area, which has created the possibility of political feudalism. Also it has created an inappropriate autonomy of institutions (inappropriate for Serbian conditions, especially when it comes to finance), with a clear debalance of quality of employees in those bodies and the system of their compensation compared to contribution given by their work. Recent political changes, "new waves" of global economic crisis and large crisis of state financing are making boom problem solving quicker, and also are putting under control the behavior of bearers of public authorization in Serbia. However, it seems that this process still lacks good and impartial methodology and argumented atmosphere for making political decisions.
The Hong Kong government has dedicated considerable resources to study and test the viability of office decentralization within the city since the 1980s, with objectives to achieve more sustainable industry spatial patterns and to relieve the Central Business District (CBD)from pressures created by high density of establishments and employment. Policies encouraging firm relocation from CBD areas to other office nodes have been implemented, and it was believed that the construction of new railway lines would facilitate such decentralization policies. In addition, a review of literature suggests that decentralization seems to be an inevitable trend in the evolution of a city. In particular, it was proposed by Smith & Selwood (1983) that decentralization could be industry-selective. \n \nWith this background, this research aims to examine whether industries in Hong Kong have actually exhibited decentralizing spatial patterns from the period 1995 to 2010and to compare trend of changes in spatial patterns among different industries. Four industries were selected as the target of study, which are (1) finance and insurance, (2) professionals services, (3) real estate, and (4) import/export, wholesale and retail trades. Their employment and establishment data at Tertiary Planning Unit (TPU) level were obtained from the Census and Statistics Department and processed. \n \nThrough the use of spatial tools, it was found that the real estate industry experienced most rapid trends of decentralization, both in establishment and employment. The other industries were less obviously decentralized; for the finance and insurance industry and the import/export, wholesale and retail industry, there even appeared indicators of stronger concentration in the study period. These findings provide strong support for future relocation policies to be industry-oriented. Another important finding is that for all industries in all study years, employment distribution tends to be more centralized than establishment distribution, which suggests that decentralizing people may be harder to achieve than decentralizing offices. It is thus envisaged that in the future, government policies regarding traffic management need to complement decentralization policies in order to alleviate transportation pressure in Hong Kong’s CBD area.
