The transition from Search to Social Media: The future of information networks The king of Web corporations has been Google with its dominance of search. Recently, Facebook has become the second-most popular website. How do the purposes of each of these successful sites differ, and where do they compete? We will argue that Facebook, Twitter and other social websites are actually becoming a replacement of Google for a key function where they overlap—identifying the information that people pay attention to. This is not a superﬁcial change. We can better understand this by considering another system that has similar concerns: the human brain. As a neuron receives messages from its input synapses it combines them in some way, ﬁltering or processing, and transmits the result to the neurons that are recipients of its output synapses. What neurons don't have is the ability to search for information they might happen to want to see out of the information that is available to the brain as a whole. Social media sites serve a similar purpose.  B.  Y.  Y.
Customized Blended Learning: The Classrooms of the Future? Online colleges may offer lessons that are personalized—to a degree. But not to the degree found at Summit High, a California charter school. The school has launched a test program that lets students personalize their own learning to an unprecedented degree. In a ninth-grade math class, some students work on geometry exercises, while others take tests in algebra, probability, and long division. Students work online, in large-group, teacher-led instruction, and in small groups. Kids get to choose the type of instruction they want—and the teacher can monitor everyone’s progress on a laptop as he moves around the room, stopping to offer individual help when needed. Even today’s typical online learning programs aren’t this personalized. Approximately 36 schools throughout the nation are trying out a combination of instructor-led and software-led instruction. But there are also plenty of reasons why highly personalized learning has big potential. The future of education is hard to gauge.
Interactive and Visual Representations Visualizing Complex Systems Science (CSS) One of NECSI's ongoing projects is to further the understanding, dissemination, and advancement of CSS by capturing key CSS concepts in visual models. Below are links to a few examples of this work in progress. About the Visual Models Generalized diagrammatic models present an abstract high-level view visualizing the fundamental phenomenon common to complexity studies. Graphics created by Marshall Clemens. How To Define Learning Objectives In education, there are goals – often of the large scale and nebulous variety: “Learn English.” “Understand fractions”. “Learn to write (well)”. Achieving this type of goal is often difficult. The handy graphic below by Mia MacMeekin takes a look at “Making Stops On The Journey”, and how defining learning outcomes gives students a destination to reach for, and an expectation to achieve. Reveal the ‘destination’ (aka the learning outcome)Prepare several objectives for the students to learn based on different learning stylesPrepare for a landing on the first objectiveCreate real life objectivesCreate objectives that teach the leaders of tomorrowMotivate your students during each learning objective
System dynamics Dynamic stock and flow diagram of model New product adoption (model from article by John Sterman 2001) System dynamics is an approach to understanding the behaviour of complex systems over time. It deals with internal feedback loops and time delays that affect the behaviour of the entire system. What makes using system dynamics different from other approaches to studying complex systems is the use of feedback loops and stocks and flows. These elements help describe how even seemingly simple systems display baffling nonlinearity. Overview System dynamics (SD) is a methodology and mathematical modeling technique for framing, understanding, and discussing complex issues and problems. Convenient GUI system dynamics software developed into user friendly versions by the 1990s and have been applied to diverse systems. System dynamics is an aspect of systems theory as a method for understanding the dynamic behavior of complex systems. History Topics in systems dynamics
Systems thinking For some, systems thinking is the cognitive process of studying and understanding systems of every kind. For others, the focus is on social organizations in particular. A system may be defined in general as a set of interrelated or interacting elements. In biology, a living organism is seen as a set of organs, muscles etc. that interact in processes to sustain the organism. The term general system theory was coined by Ludwig von Bertalanffy in the middle of the 20th century. An early focus of general system theory was on homeostatic or self-regulating systems that maintain themselves in a consistent or viable state through input/output feedback loops. Sociological systems thinking started much earlier, in the 19th century. History and overview Impression of systems thinking about society. Systems thinking has been defined as an approach to problem solving that attempts to balance holistic thinking and reductionistic thinking. The concept of a system Stephen G.
U.S. Department of Energy's Introduction to System Dynamics U.S. Department of Energy's Introduction to System Dynamics(V 1.0) Welcome to the Office of Policy and International Affairs's Introduction to System Dynamics (V1.0). Energy policy is well suited for a "systems approach" because those who study, design, and implement national energy policy must not only understand the complexities of our nation's energy sector, but how energy issues influence and "connect" with national policy concerns such as economic growth, technology development, national security, international trade, and environmental conservation, just to name a few. System dynamics helps the decision maker untangle the complexity of these connections by providing a new language and set of tools to describe - and even model - the cause-and-effect relationships among various policy variables.
Dynamics of Complex Systems Textbook for seminar/course on complex systems.View full text in PDF format The study of complex systems in a unified framework has become recognized in recent years as a new scientific discipline, the ultimate of interdisciplinary fields. Breaking down the barriers between physics, chemistry and biology and the so-called soft sciences of psychology, sociology, economics, and anthropology, this text explores the universal physical and mathematical principles that govern the emergence of complex systems from simple components. Dynamics of Complex Systems is the first text describing the modern unified study of complex systems. It is designed for upper-undergraduate/beginning graduate-level students, and covers a wide range of applications in a wide array of disciplines. A central goal of this text is to develop models and modeling techniques that are useful when applied to all complex systems.
How to Detect Lies - body language, reactions, speech patterns Interesting Info -> Lying Index -> How to Detect Lies Become a Human Lie Detector (Part 1) Warning: sometimes ignorance is bliss. After gaining this knowledge, you may be hurt when it is obvious that someone is lying to you. Introduction to Detecting Lies: This knowledge is also useful for managers, employers, and for anyone to use in everyday situations where telling the truth from a lie can help prevent you from being a victim of fraud/scams and other deceptions. This is just a basic run down of physical (body language) gestures and verbal cues that may indicate someone is being untruthful. If you got here from somewhere else, be sure to check out our Lie Detection index page for more info including new research in the field of forensic psychology. Signs of Deception: Body Language of Lies: • Physical expression will be limited and stiff, with few arm and hand movements. • A person who is lying to you will avoid making eye contact. • Hands touching their face, throat & mouth. Final Notes:
Rats Capable Of Reflecting On Mental Processes -- ScienceDaily Let's say a college student enters a classroom to take a test. She probably already has an idea how she will do on the test, before she even takes out a pencil. But do animals possess the same ability to think about what they know or don't know? A new study by researchers from the University of Georgia, just published in the journal Current Biology, shows that laboratory rats do. "This kind of research may change how we think about cognition and memory in animals," said Jonathon Crystal, an associate professor of psychology in UGA's Franklin College of Arts and Sciences. Researchers have believed for some time that people and non-human primates are capable of "metacognition"--reasoning or thinking about one's own thinking. The study involved what is called a "duration-discrimination" test--offering rats rewards for classifying a signal as either short or long. It's easy to find out when humans believe they know or don't know the answer to a task or test.

Jennifer Egan on Writing, the Trap of Approval, and the Most Important Discipline for Aspiring Writers “You can only write regularly if you’re willing to write badly… Accept bad writing as a way of priming the pump, a warm-up exercise that allows you to write well.”
Nietzsche’s 10 Rules for Writers, Penned in a Letter to His Lover and Muse More than a century before Elmore Leonard’s ten rules of writing inspired similar sets of commandments by Neil Gaiman, Zadie Smith, and Margaret Atwood, one of humanity’s greatest minds did precisely that. Between August 8 and August 24 of 1882, Friedrich Nietzsche set down ten stylistic rules of writing in a series of letters to the Russian-born writer, intellectual, and psychoanalyst Lou Andreas-Salomé — the first female psychoanalyst, who corresponded with Freud about human nature, and an extraordinary woman celebrated as the “muse of Europe’s fin-de-siècle thinkers and artists,” to whom Rainer Maria Rilke would later come to write breathtaking love letters. Smitten with 21-year-old Andreas-Salomé, Nietzsche decided to make her not only his intellectual protégé, but also his wife, allegedly proposing marriage at only their second meeting earlier that year. Collected under the heading “Toward the Teaching of Style,” they read: These commandments are obviously rather aphoristic.
[M06] Necessity and sufficiency The concepts of necessary and sufficient conditions help us understand and explain the different kinds of connections between concepts, and how different states of affairs are related to each other. §1. Necessary conditions To say that X is a necessary condition for Y is to say that it is impossible to have Y without X. In other words, the absence of X guarantees the absence of Y. A necessary condition is sometimes also called "an essential condition". Having four sides is necessary for being a square.Being brave is a necessary condition for being a good soldier.Not being divisible by four is essential for being a prime number. To show that X is not a necessary condition for Y, we simply find a situation where Y is present but X is not. Additional remarks about necessary conditions : We invoke the notion of a necessary condition very often in our daily life, even though we might be using different terms. §2. Loving someone is not sufficient for being loved. §3. Exercise #1 Exercise #2
