Glossary of systems theory A glossary of terms as relating to systems theory.[1] A[edit] B[edit] C[edit] Cascading failure: failure in a system of interconnected parts, where the service provided depends on the operation of a preceding part, and the failure of a preceding part can trigger the failure of successive parts.Closed system: a system which can exchange energy (as heat or work), but not matter, with its surroundings.Complexity: A systemic characteristic that stands for a large number of densely connected parts and multiple levels of embeddedness and entanglement. D[edit] Development: The process of liberating a system from its previous set of limiting conditions. E[edit] F[edit] H[edit] I[edit] Isolated system: A system in which the total energy-mass is conserved without any external exchange happening. L[edit] Lowerarchy: A specific type of hierarchy involving a ‘bottom up’ arrangement of entities such that the few are influenced by the many.

Negative Thinking A CEO calls her staff into the conference room on the eve of the launch of a major new initiative. They file in and take their seats around the table. She calls the meeting to attention and begins, “I have bad news. The project has failed spectacularly. What went wrong?” The team is perplexed: What?! I know it seems strange and maybe even counterproductive to demand that employees think negatively instead of optimistically, but in business circles today, everyone from startups to Fortune 500 companies and the Harvard Business Review are doing this exact exercise. The technique that the CEO above was using was designed by psychologist Gary Klein. Stocklite/Shutterstock In fact, I think more companies need a Chief Dissent Officer, someone to shoot down the bad ideas that our blind spots and naive optimism too often obscure. The practice goes back much further than just psychology though. A writer like Seneca would begin by reviewing or rehearsing his plans, say, to take a trip.
Home Brain Structures and Their Functions The nervous system is your body's decision and communication center. The central nervous system (CNS) is made of the brain and the spinal cord and the peripheral nervous system (PNS) is made of nerves. Together they control every part of your daily life, from breathing and blinking to helping you memorize facts for a test. The brain is made of three main parts: the forebrain, midbrain, and hindbrain. The Cerebrum: The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action. What do each of these lobes do? Frontal Lobe- associated with reasoning, planning, parts of speech, movement, emotions, and problem solving Parietal Lobe- associated with movement, orientation, recognition, perception of stimuli Occipital Lobe- associated with visual processing Temporal Lobe- associated with perception and recognition of auditory stimuli, memory, and speech Note that the cerebral cortex is highly wrinkled.

Systems - A Journey Along the Way Systems A Journey Along theWay Welcome to a journey in the realm of systems. The journey is still unfolding as this web site continues to evolve over time. Yet, even with the endless changes, there continues to be a connection, in one fashion or another, with systems. And, I continue to find that the lens which provides a systems perspective is the most revealing of understanding found to date. The real intent here is not to study systems as a discipline, though more an intent to study lots of things and employ a systems perspective to foster understanding. Every attempt will be made to avoid the major failing of "system science." Enjoy the journey! System The word system probably has more varied meanings than any other word in use today. A system is an entity which maintains its existence through the mutual interaction of its parts. The key emphasis here is "mutual interaction," in that something is occurring between the parts, over time, which maintains the system. Emergence Threat System
Study showing that humans have some psychic powers caps Daryl Bem's career It took eight years and nine experiments with more 1,000 participants, but the results offer evidence that humans have some ability to anticipate the future. "Of the various forms of ESP or psi, as we call it, precognition has always most intrigued me because it's the most magical," said Daryl Bem, professor of psychology emeritus, whose study will be published in the American Psychological Association's Journal of Personality and Social Psychology sometime next year. "It most violates our notion of how the physical world works. The phenomena of modern quantum physics are just as mind-boggling, but they are so technical that most non-physicists don't know about them," said Bem, who studied physics before becoming a psychologist. Publishing on this topic has gladdened the hearts of psi researchers but stumped doubting social psychologists, who cannot fault Bem's mainstream and widely accepted methodology. All but one of the nine experiments confirmed the hypothesis that psi exists.
