central authority
2021
A central authority, in a conventional centralized energy trading market, superintends energy and financial transactions. The central authority manages and controls transparent energy trading between producer and consumer, imposes a penalty in case of contract violation, and disburses numerous rewards. However, the management and control through the third party pose a significant threat to the security and privacy of consumers’/producers’ (participants) profiles. The energy transactions between participants involving central authority utilize users’ time, money, and impose a computational burden over the central controlling authority. The Blockchain-based decentralized energy transaction concept, bypassing the central authority, is proposed in Smart Grid (SG) by researchers. Blockchain technology braces the concept of Peer-to-Peer (P2P) energy transactions. This work encompasses the SolarCoin-based digital currency blockchain model for SG incorporating RE. Energy transactions from Prosumer (P) to Prosumer, Energy District to Energy District, and Energy District to SG are thoroughly investigated and analyzed in this work. A robust demand-side optimized model is proposed using Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) to maximize Prosumer Energy Surplus (PES), Grid revenue (GR), percentage energy transactions accomplished, and decreased Prosumer Energy Cost (PEC). Real-time averaged energy data of Australia are employed, and a piece-wise energy price mechanism is implemented in this work. The graphical analysis and tabular statistics manifest the efficacy of the proposed model.

Federalism and subsidiarity
\"In Federalism and Subsidiarity, a distinguished interdisciplinary group of scholars in political science, law, and philosophy address the application and interaction of the concept of federalism within law and government. What are the best justifications for and conceptions of federalism? What are the most useful criteria for deciding what powers should be allocated to national governments and what powers reserved to state or provincial governments? What are the implications of the principle of subsidiarity for such questions? What should be the constitutional standing of cities in federations? Do we need to \"remap\" federalism to reckon with the emergence of translocal and transnational organizations with porous boundaries that are not reflected in traditional jurisdictional conceptions? Examining these questions and more, this latest installation in the NOMOS series sheds new light on the allocation of power within federations\"-- Provided by publisher.
Cities of Commerce
2013
Cities of Commerce develops a model of institutional change in European commerce based on urban rivalry. Cities continuously competed with each other by adapting commercial, legal, and financial institutions to the evolving needs of merchants. Oscar Gelderblom traces the successive rise of Bruges, Antwerp, and Amsterdam to commercial primacy between 1250 and 1650, showing how dominant cities feared being displaced by challengers while lesser cities sought to keep up by cultivating policies favorable to trade. He argues that it was this competitive urban network that promoted open-access institutions in the Low Countries, and emphasizes the central role played by the urban power holders--the magistrates--in fostering these inclusive institutional arrangements. Gelderblom describes how the city fathers resisted the predatory or reckless actions of their territorial rulers, and how their nonrestrictive approach to commercial life succeeded in attracting merchants from all over Europe.
Cities of Commerce intervenes in an important debate on the growth of trade in Europe before the Industrial Revolution. Challenging influential theories that attribute this commercial expansion to the political strength of merchants, this book demonstrates how urban rivalry fostered the creation of open-access institutions in international trade.
ECONOMIC AND SOCIAL FACTORS IMPACTING SMALL AND MEDIUM-SIZED ENTERPRISES IN ISRAEL
2021
The development of local entrepreneurship has become an integral part of the urban culture, creating an interest in the impact of small and medium-sized enterprises on the local economy, the satisfaction of the residents and their desire to remain in the city and bring up the next generation in their place of residence. A qualitative research approach, using semi-structured interviews with stakeholders of small and medium-sized enterprises in several cities in Israel was adopted to examine the situation of small and medium-sized enterprises from an economic, and social perspective. The findings indicated that while the local businesses fulfill a role in the social fabric of the city by connecting residents to their urban place of residence, the small and medium-sized enterprises are struggling economically, since they are faced with heavy competition from chain stores, malls and trading centers established in the peripheral regions.

Creating the national security state
2008,2009
For the last sixty years, American foreign and defense policymaking has been dominated by a network of institutions created by one piece of legislation--the 1947 National Security Act. This is the definitive study of the intense political and bureaucratic struggles that surrounded the passage and initial implementation of the law. Focusing on the critical years from 1937 to 1960, Douglas Stuart shows how disputes over the lessons of Pearl Harbor and World War II informed the debates that culminated in the legislation, and how the new national security agencies were subsequently transformed by battles over missions, budgets, and influence during the early cold war.
Stuart provides an in-depth account of the fight over Truman's plan for unification of the armed services, demonstrating how this dispute colored debates about institutional reform. He traces the rise of the Office of the Secretary of Defense, the transformation of the CIA, and the institutionalization of the National Security Council. He also illustrates how the development of this network of national security institutions resulted in the progressive marginalization of the State Department.
Stuart concludes with some insights that will be of value to anyone interested in the current debate over institutional reform.
More Talk, Less Need for Monitoring: Communication and Deterrence in a Public Good Game
2018
This paper investigates the impact of communication in a public good game with a central authority. The central authority includes a fixed cost that increases with the level of monitoring which in turn determines the level of deterrence. The level of monitoring is both exogenously and endogenously determined. Across three treatments subjects either have no opportunity to communicate, communicate only when the level of monitoring is exogenously imposed, or communicate only when the level of monitoring is endogenously selected. Results suggest that, in both treatments, average earnings are significantly higher with the opportunity to communicate. Most significantly, with the opportunity to communicate prior to endogenous selection, groups practically eliminate monitoring (imposing a low cost, non-deterrent, central authority), while maintaining a high level of contributions. Communication appears to make groups less dependent on institutional deterrence and allows them to reduce the costs of central authority.

La insubordinación a la autoridad central y los mecanismos regios de contención durante el reino astur-leonés (siglos VIII-XI)
2024
El gobierno de Bermudo II (982-999) sobresale como la etapa álgida de los movimientos de rebelión durante el reino astur-leonés. Los diferentes aportes historiográficos han intentado explicar las motivaciones que empujaban a determinados individuos a cometer estas acciones, mientras que las represiones ejercidas por la monarquía apenas han captado la atención de los investigadores, pues se comprenden como una causa natural del castigo impuesto a los sediciosos. En mi aportación, trataré de analizar las distintas categorías de sedición y sus consecuencias atendiendo a un contexto diacrónico y a la construcción de redes clientelares con el objetivo de confirmar o desmentir la imagen sobre la presunta fragilidad de la autoridad central durante la segunda mitad del siglo X.

Empowered participation
2009,2004,2006
Every month in every neighborhood in Chicago, residents, teachers, school principals, and police officers gather to deliberate about how to improve their schools and make their streets safer. Residents of poor neighborhoods participate as much or more as those from wealthy ones. All voices are heard. Since the meetings began more than a dozen years ago, they have led not only to safer streets but also to surprising improvements in the city's schools. Chicago's police department and school system have become democratic urban institutions unlike any others in America.
Empowered Participationis the compelling chronicle of this unprecedented transformation. It is the first comprehensive empirical analysis of the ways in which participatory democracy can be used to effect social change. Using city-wide data and six neighborhood case studies, the book explores how determined Chicago residents, police officers, teachers, and community groups worked to banish crime and transform a failing city school system into a model for educational reform. The author's conclusion: Properly designed and implemented institutions of participatory democratic governance can spark citizen involvement that in turn generates innovative problem-solving and public action. Their participation makes organizations more fair and effective.
Though the book focuses on Chicago's municipal agencies, its lessons are applicable to many American cities. Its findings will prove useful not only in the fields of education and law enforcement, but also to sectors as diverse as environmental regulation, social service provision, and workforce development.
The last pharaohs
2010,2009
The history of Ptolemaic Egypt has usually been doubly isolated--separated both from the history of other Hellenistic states and from the history of ancient Egypt.The Last Pharaohs, the first detailed history of Ptolemaic Egypt as a state, departs radically from previous studies by putting the Ptolemaic state firmly in the context of both Hellenistic and Egyptian history. More broadly still, J. G. Manning examines the Ptolemaic dynasty in the context of the study of authoritarian and premodern states, shifting the focus of study away from modern European nation-states and toward ancient Asian ones. By analyzing Ptolemaic reforms of Egyptian economic and legal structures,The Last Pharaohsgauges the impact of Ptolemaic rule on Egypt and the relationships that the Ptolemaic kings formed with Egyptian society. Manning argues that the Ptolemies sought to rule through--rather than over--Egyptian society. He tells how the Ptolemies, adopting a pharaonic model of governance, shaped Egyptian society and in turn were shaped by it. Neither fully Greek nor wholly Egyptian, the Ptolemaic state within its core Egyptian territory was a hybrid that departed from but did not break with Egyptian history. Integrating the latest research on archaeology, papyrology, theories of the state, and legal history, as well as Hellenistic and Egyptian history,The Last Pharaohsdraws a dramatically new picture of Egypt's last ancient state.
