MultilateralismIn international relations, multilateralism refers to an alliance of multiple countries pursuing a common goal. Multilateralism, in the form of membership in international institutions, serves to bind powerful nations, discourage unilateralism, and gives small powers a voice and influence that they could not otherwise exercise. For a small power to influence a great power, the Lilliputian strategy of small countries banding together to collectively bind a larger one can be effective.
Multistakeholder governanceMultistakeholder governance is a practice of governance that employs bringing multiple stakeholders together to participate in dialogue, decision making, and implementation of responses to jointly perceived problems. The principle behind such a structure is that if enough input is provided by multiple types of actors involved in a question, the eventual consensual decision gains more legitimacy, and can be more effectively implemented than a traditional state-based response.
Sequence spaceIn functional analysis and related areas of mathematics, a sequence space is a vector space whose elements are infinite sequences of real or complex numbers. Equivalently, it is a function space whose elements are functions from the natural numbers to the field K of real or complex numbers. The set of all such functions is naturally identified with the set of all possible infinite sequences with elements in K, and can be turned into a vector space under the operations of pointwise addition of functions and pointwise scalar multiplication.
Space lawSpace law is the body of law governing space-related activities, encompassing both international and domestic agreements, rules, and principles. Parameters of space law include space exploration, liability for damage, weapons use, rescue efforts, environmental preservation, information sharing, new technologies, and ethics. Other fields of law, such as administrative law, intellectual property law, arms control law, insurance law, environmental law, criminal law, and commercial law, are also integrated within the space law.
Socio-ecological systemA social-ecological system consists of 'a bio-geo-physical' unit and its associated social actors and institutions. Social-ecological systems are complex and adaptive and delimited by spatial or functional boundaries surrounding particular ecosystems and their context problems. A social-ecological system (SES) can be defined as:(p.
Banach spaceIn mathematics, more specifically in functional analysis, a Banach space (pronounced ˈbanax) is a complete normed vector space. Thus, a Banach space is a vector space with a metric that allows the computation of vector length and distance between vectors and is complete in the sense that a Cauchy sequence of vectors always converges to a well-defined limit that is within the space. Banach spaces are named after the Polish mathematician Stefan Banach, who introduced this concept and studied it systematically in 1920–1922 along with Hans Hahn and Eduard Helly.
Isoelastic utilityIn economics, the isoelastic function for utility, also known as the isoelastic utility function, or power utility function, is used to express utility in terms of consumption or some other economic variable that a decision-maker is concerned with. The isoelastic utility function is a special case of hyperbolic absolute risk aversion and at the same time is the only class of utility functions with constant relative risk aversion, which is why it is also called the CRRA utility function.
Environmental, social, and corporate governanceEnvironmental, social, and corporate governance (ESG), also known as environmental, social, and governance, is a set of aspects considered when investing in companies, that recommends taking environmental issues, social issues and corporate governance issues into account. Since 2020, there have been accelerating incentives from the United Nations (UN) to overlay ESG data with the Sustainable Development Goals (SDGs), based on their work, which began in the 1980s.
Commons-based peer productionCommons-based peer production (CBPP) is a term coined by Harvard Law School professor Yochai Benkler. It describes a model of socio-economic production in which large numbers of people work cooperatively; usually over the Internet. Commons-based projects generally have less rigid hierarchical structures than those under more traditional business models. One of the major characteristics of the commons-based peer production is its non-profit scope. Often—but not always—commons-based projects are designed without a need for financial compensation for contributors.
Common-pool resourceIn economics, a common-pool resource (CPR) is a type of good consisting of a natural or human-made resource system (e.g. an irrigation system or fishing grounds), whose size or characteristics makes it costly, but not impossible, to exclude potential beneficiaries from obtaining benefits from its use. Unlike pure public goods, common pool resources face problems of congestion or overuse, because they are subtractable. A common-pool resource typically consists of a core resource (e.g.
Hyperbolic absolute risk aversionIn finance, economics, and decision theory, hyperbolic absolute risk aversion (HARA) refers to a type of risk aversion that is particularly convenient to model mathematically and to obtain empirical predictions from. It refers specifically to a property of von Neumann–Morgenstern utility functions, which are typically functions of final wealth (or some related variable), and which describe a decision-maker's degree of satisfaction with the outcome for wealth. The final outcome for wealth is affected both by random variables and by decisions.
