Behavioral operations management 1970-01-01
Behavioral operations management is a field that integrates insights from behavioral science and psychology into the study and practice of operations management. It focuses on understanding how human behavior and decision-making processes affect operational performance, efficiency, and effectiveness within organizations. This discipline recognizes that traditional operations management models often assume rational behavior and optimal decision-making by individuals and teams.
Confrontation analysis 1970-01-01
Confrontation analysis is a problem-solving and decision-making methodology that focuses on identifying and addressing conflicting interests and positions among stakeholders in a given context. This approach is particularly useful in situations where there is competition, debate, or disagreement, such as in politics, business negotiations, social issues, and conflict resolution. Key components of confrontation analysis typically include: 1. **Stakeholder Identification**: Identifying all parties involved and understanding their interests, positions, and power dynamics.
Drama theory 1970-01-01
Drama theory is a conceptual framework used to analyze and understand interactions and conflicts within social, organizational, and political contexts. It draws heavily from the principles of theatrical drama to model human behavior, decision-making, and negotiation processes. While there isn't a universally accepted definition, drama theory posits that individuals are often motivated by personal stories or narratives that drive their actions in conflict situations.
EURO Advanced Tutorials in Operational Research 1970-01-01
EURO Advanced Tutorials in Operational Research is a series of educational resources and materials aimed at providing in-depth knowledge and insights into various areas of operational research (OR). OR is a field of study that uses mathematical modeling, statistical analysis, and optimization techniques to aid decision-making in complex systems across various domains, including logistics, finance, healthcare, and manufacturing. The EURO (Association of European Operational Research Societies) organization typically collaborates with leading experts in the field to develop these tutorials.
Program evaluation and review technique 1970-01-01
Program Evaluation and Review Technique (PERT) is a project management tool used to analyze and represent the tasks involved in completing a given project. It was developed in the 1950s for the Polaris submarine project and is especially useful for projects with uncertain activity durations. ### Key Features of PERT: 1. **Graphical Representation**: PERT uses a flowchart-like diagram to represent project tasks and their interrelationships. Each task is depicted as a node or a milestone.
Scheduling (computing) 1970-01-01
In computing, scheduling refers to the method by which tasks are assigned to resources, particularly in the context of operating systems and process management. The goal of scheduling is to efficiently manage the execution of multiple processes or threads on a computer system, optimizing resource utilization, responsiveness, and overall performance. ### Types of Scheduling 1. **Long-term Scheduling**: Determines which processes are admitted to the system for processing. It controls the degree of multiprogramming (the number of processes in memory).
Seven management and planning tools 1970-01-01
The Seven Management and Planning Tools (7MP) are a set of strategic and operational tools used for problem-solving, project management, and planning in organizations. These tools help teams improve communication, enhance decision-making, and facilitate effective planning processes. The seven tools are: 1. **Affinity Diagram**: This tool helps in organizing ideas and data into groups based on their natural relationships. It's particularly useful for brainstorming sessions, where many ideas need to be categorized and prioritized.
Transportation Science 1970-01-01
Transportation Science is an interdisciplinary field that focuses on the analysis, design, and optimization of transportation systems and their components. It encompasses various aspects of transportation, including infrastructure, vehicles, operations, logistics, and policy. The goal of Transportation Science is to improve the efficiency, safety, reliability, and sustainability of transportation systems while addressing issues like traffic congestion, environmental impacts, and public safety.
Nomological danglers 1970-01-01
Nomological danglers refer to phenomena or observations that cannot be adequately explained by a given scientific theory or framework. The term is often used in discussions about the philosophy of science, particularly in relation to scientific theories, laws, and explanations. When a scientific theory encounters data or phenomena that it cannot account for, these anomalies can be seen as "dangling" outside the theoretical framework. This situation may indicate that the theory is incomplete, flawed, or in need of revision.
Black drop effect 1970-01-01
The "black drop effect" is an optical phenomenon that occurs during the transit of a planet across the face of the Sun, typically observed during transits of Venus or Mercury. It manifests as a distortion of the planet's silhouette, where the edges appear to be blunted or "dropped" against the Sun's bright disk. This effect makes it seem as if the planet is connected to the Sun by a dark "tail" or that it has a larger apparent size than it actually does.
Blue field entoptic phenomenon 1970-01-01
The Blue Field Entoptic Phenomenon, also known as "Blue Field Vision," is a visual phenomenon characterized by the perception of small, bright dots moving rapidly across a blue background, particularly when looking at a clear blue sky. These dots are not external objects; rather, they are the shadowy silhouettes of white blood cells moving through the capillaries in the retina.
Chatoyancy 1970-01-01
Chatoyancy, often referred to as "cat's eye effect," is an optical phenomenon seen in certain gemstones and materials that exhibit a bright, narrow band of reflected light. This effect resembles the slit eye of a cat, hence the name. Chatoyancy occurs due to the presence of fibrous inclusions or parallel needle-like structures within the gemstone, which reflect light in a specific way.
Entoptic phenomenon 1970-01-01
An entoptic phenomenon refers to visual effects that originate from within the eye itself, rather than from external visual stimuli. These phenomena typically arise from the structures of the eye, such as the retina or the vitreous humor, and can manifest as various visual sensations or disturbances.
Extinction cross 1970-01-01
The term "extinction cross" commonly refers to a specific concept in the field of ecology and conservation biology. It generally pertains to the intersection of two extinction dynamics: the extinction of species and the loss of genetic diversity within those species. In a broader sense, it can also represent the interaction between various factors leading to species extinction, such as habitat loss, climate change, invasive species, and human activity.
Förster resonance energy transfer 1970-01-01
Förster resonance energy transfer (FRET) is a physical phenomenon that describes the transfer of energy from an excited donor molecule to an acceptor molecule through non-radiative dipole-dipole interactions. This process occurs when the two molecules are in close proximity, typically within 1 to 10 nanometers.
Gegenschein 1970-01-01
Gegenschein is a faint brightness or glow in the night sky that is seen opposite the Sun, usually in the ecliptic plane. It is part of a phenomenon known as zodiacal light. The gegenschein appears as a small, diffuse patch of light, and it is most noticeable in very dark skies far from any artificial light. This glow is caused primarily by sunlight scattering off interplanetary dust particles that are located in the solar system.
Giant birefringence 1970-01-01
Giant birefringence refers to an extreme form of birefringence observed in certain materials, where the difference in the refractive indices of the fast and slow optical axes is significantly large, sometimes on the order of several orders of magnitude higher than normal birefringent materials. Birefringence occurs in anisotropic materials, where the speed of light varies depending on the direction of propagation through the material.
Goos–Hänchen effect 1970-01-01
The Goos–Hänchen effect is a phenomenon observed in the field of optics and wave physics, particularly in the context of total internal reflection. It describes the lateral displacement of a light beam when it reflects off the boundary between two different media at an angle greater than the critical angle. When a light wave hits the interface between two media (like air and glass) at an angle greater than the critical angle, it undergoes total internal reflection.
Gravitational mirage 1970-01-01
A gravitational mirage, more commonly referred to as gravitational lensing, is a phenomenon that occurs when the gravitational field of a massive object, such as a galaxy or cluster of galaxies, distorts the light from objects that are located behind it. This effect arises from the predictions of Einstein's General Theory of Relativity, which posits that mass can curve spacetime. When light from a distant star or galaxy passes near a massive object, the object's gravity bends the light's path.
Simulation hypothesis 1970-01-01
The simulation hypothesis is a philosophical proposition suggesting that what we perceive as reality might be an artificial simulation, such as a computer simulation. This idea posits that advanced civilizations, capable of creating highly sophisticated simulations, might run simulations of their ancestors or environments, making it possible that we are living in one of these simulated realities.
