An intergovernmental organization (IGO) is an organization composed primarily of sovereign states (referred to as member states), or of other organizations through formal treaties for handling/serving common interests and governed by international laws. IGOs are established by a treaty that acts as a charter creating the group. Treaties are formed when lawful representatives (governments) of several states go through a ratification process, providing the IGO with an international legal personality. Intergovernmental organizations are an important aspect of public international law.
Intergovernmental organizations in a legal sense should be distinguished from simple groupings or coalitions of states, such as the G7 or the Quartet. Such groups or associations have not been founded by a constituent document and exist only as task groups. Intergovernmental organizations must also be distinguished from treaties.
The Commonwealth of Nations, generally known simply as the Commonwealth, is a political association of 54 member states, almost all of which are former territories of the British Empire. The chief institutions of the organisation are the Commonwealth Secretariat, which focuses on intergovernmental aspects, and the Commonwealth Foundation, which focuses on non-governmental relations amongst member states.
The Commonwealth dates back to the first half of the 20th century with the decolonisation of the British Empire through increased self-governance of its territories. It was originally created as the British Commonwealth of Nations through the Balfour Declaration at the 1926 Imperial Conference, and formalised by the United Kingdom through the Statute of Westminster in 1931. The current Commonwealth of Nations was formally constituted by the London Declaration in 1949, which modernised the community and established the member states as "free and equal".
The United Nations defines community development as "a process where community members come together to take collective action and generate solutions to common problems." It is a broad concept, applied to the practices of civic leaders, activists, involved citizens, and professionals to improve various aspects of communities, typically aiming to build stronger and more resilient local communities.
Community development is also understood as a professional discipline, and is defined by the International Association for Community Development as "a practice-based profession and an academic discipline that promotes participative democracy, sustainable development, rights, economic opportunity, equality and social justice, through the organisation, education and empowerment of people within their communities, whether these be of locality, identity or interest, in urban and rural settings".
The Treaty on the Functioning of the European Union (TFEU) is one of two treaties forming the constitutional basis of the European Union (EU), the other being the Treaty on European Union (TEU. It was previously known as Treaty Establishing the European Community (TEC).
The Treaty originated as the Treaty of Rome (fully the Treaty establishing the European Economic Community), which brought about the creation of the European Economic Community (EEC), the best-known of the European Communities (EC). It was signed on 25 March 1957 by Belgium, France, Italy, Luxembourg, the Netherlands and West Germany and came into force on 1 January 1958. It remains one of the two most important treaties in the modern-day European Union (EU).
Its name has been amended twice since 1957. The Maastricht Treaty of 1992 removed the word "economic" from the Treaty of Rome's official title and, in 2009, the Treaty of Lisbon renamed it the "Treaty on the Functioning of the European Union".
A capital requirement (also known as regulatory capital or capital adequacy) is the amount of capital a bank or other financial institution has to have as required by its financial regulator. This is usually expressed as a capital adequacy ratio of equity as a percentage of risk-weighted assets. These requirements are put into place to ensure that these institutions do not take on excess leverage and risk becoming insolvent. Capital requirements govern the ratio of equity to debt, recorded on the liabilities and equity side of a firm's balance sheet. They should not be confused with reserve requirements, which govern the assets side of a bank's balance sheet—in particular, the proportion of its assets it must hold in cash or highly-liquid assets. Capital is a source of funds not a use of funds.
The Treaty Establishing the European Stability Mechanism was signed by the member states of the eurozone to found the European Stability Mechanism (ESM), an international organisation located in Luxembourg, to act as a permanent source of financial assistance for member states in financial difficulty, with a maximum lending capacity of €500 billion. It replaced two earlier temporary EU funding programmes: the European Financial Stability Facility (EFSF) and the European Financial Stabilisation Mechanism (EFSM). All new bailouts of eurozone member states will be covered by ESM, while the EFSF and EFSM will continue to handle money transfers and program monitoring for bailouts previously approved for Ireland, Portugal and Greece.
International law, also known as public international law and law of nations, is the set of rules, norms, and standards generally recognized as binding between nations. It establishes normative guidelines and a common conceptual framework for states across a broad range of domains, including war, diplomacy, trade, and human rights. International law aims to promote the practice of stable, consistent, and organized international relations.
The sources of international law include international custom (general state practice accepted as law), treaties, and general principles of law recognized by most national legal systems. International law may also be reflected in international comity, the practices and customs adopted by states to maintain good relations and mutual recognition, such as saluting the flag of a foreign ship or enforcing a foreign legal judgment.
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves.
Physics is one of the oldest academic disciplines and, through its inclusion of astronomy, perhaps the oldest. Over much of the past two millennia, physics, chemistry, biology, and certain branches of mathematics were a part of natural philosophy, but during the Scientific Revolution in the 17th century these natural sciences emerged as unique research endeavors in their own right. Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined.
In mathematics, structural stability is a fundamental property of a dynamical system which means that the qualitative behavior of the trajectories is unaffected by small perturbations.
Examples of such qualitative properties are numbers of fixed points and periodic orbits. Unlike Lyapunov stability, which considers perturbations of initial conditions for a fixed system, structural stability deals with perturbations of the system itself. Variants of this notion apply to systems of ordinary differential equations, vector fields on smooth manifolds and flows generated by them, and diffeomorphisms.
Structurally stable systems were introduced by Aleksandr Andronov and Lev Pontryagin in 1937 under the name "systèmes grossiers", or rough systems. They announced a characterization of rough systems in the plane, the Andronov–Pontryagin criterion. In this case, structurally stable systems are typical, they form an open dense set in the space of all systems endowed with appropriate topology.
Certain works of structural engineering design are also works of structural art. Such works can be classified as structural art when they attain excellence in the three areas of efficiency, economy, and elegance, as defined by Prof. David P. Billington of Princeton University. A key part of the concept of structural art is that the structural engineer making the design must exercise his or her creativity and playfulness to create an elegant structure within the constraints imposed by engineering requirements. Structural art is a topic of active scholarly research at several universities in the United States, including Princeton University, University of Massachusetts Amherst, and Roger Williams University, and in other parts of the world such as Spain and Germany. While structural artists often collaborate with architects, the discipline of structural art is based upon engineering rather than architectural design. A recent summary about this topic can be found in a review paper.
