Global Thoughts, Local Action: a case of comparative EFL teacher education
Teacher education is deemed to play a critical role in revolutionizing any education system. As a result, pre-service teacher education has received considerable attention in education systems world over. In the context of Iran, the process of teacher education has not been properly implemented and following their being recruited teachers would go directly to classes, without possessing adequat...
متن کاملRecognizing Action at a Distance
Our goal is to recognize human actions at a distance, at resolutions where a whole person may be, say, 30 pixels tall. We introduce a novel motion descriptor based on optical flow measurements in a spatio-temporal volume for each stabilized human figure, and an associated similarity measure to be used in a nearest-neighbor framework. Making use of noisy optical flow measurements is the key chal...
متن کاملAction-at-a-Distance and Local Action in Gravitation: Discussion and Possible Solution of the Dilemma
The problem of the character of gravitation is approached by discussing three main possible modes of action from the historical, theoretical and empirical standpoints. The “Newtonian” mode of action-at-a-distance (AAAD)—in which Newton himself did not believe—is followed through three centuries, though the aim is not historical accuracy. This approach includes several Webertype theories of velo...
متن کاملCasimir Forces in Chiral Metamaterials
We use the extended Lifshitz theory to study the behavior of the Casimir forces between chiral metamaterials and regular metamaterials. We have shown that the chirality, if strong enough, is of critical importance to reduce the Cassimir attractive force and can find new designs to obtain repulsive Casimir forces. We will review chiral metamaterials and find some analytical expression for the st...
متن کاملGlobal/Local Subtyping for a Distributed -calculus
Abstract In the design of mobile agent programming languages there is a tension between the implementation cost and the expressiveness of the communication mechanisms provided. This paper gives a static type system for a distributed -calculus in which the input and output capabilities of channels may be either global or local. This allows compile-time optimization where possible but retains the...
