Chaos/Complexity Theory and Education
Sciences exist to demonstrate the fundamental order underlying nature. Chaos/complexity theory is a novel and amazing field of scientific inquiry. Notions of our everyday experiences are somehow in connection to the laws of nature through chaos/complexity theory’s concerns with the relationships between simplicity and complexity, between orderliness and randomness (Retrieved from http://www.inc...

QSAT (QBF) INSTANCE: Boolean expression φ in CNF with variables x1, . . . , xn. QUESTION: Is there a truth value for the variable x1 such that for both truth values of x2 there is a truth value for x3 and so on up to xn, such that φ is satisfied by the overall truth assignment? Notation An instance of QSAT is written as ∃x1∀x2∃x3 · · ·Qxnφ, where Q is ∀ if n is even and ∃ if n is odd. Theorem Q...
متن کاملHistory and the sizes of cities
We discuss the tension between some of the recent evidence of path dependence in urban location with recent efforts to analyze calibrated models of city sizes. One strand of recent work, including some of our own, finds evidence of persistent city sizes following the obsolescence of historical advantages. This literature argues that such persistence cannot be understood as the medium-run effect...

بر اساس فرضیه شناخت رابینسون (2001 و 2003 و 2005) و مدل ظرفیت توجه محدود اسکهان (1998)، این تحقیق تاثیر پیچیدگی تکلیف را بر پیچیدگی واژگان و صحت گرامری نوشتار مباحثه ای 60 نفر از دانشجویان زبان انگلیسی بررسی کرد. میزان پیچیدگی تکلیف از طریق فاکتورهای پراکندگی-منابع تعیین شد. همه ی شرکت کنندگان به صورت نیمه تصادفی به یکی از سه گروه: (1) گروه موضوع، (2) گروه موضوع + اندیشه و (3) گروه موضوع + اندی...
