Central of these services is consumers’ satisfaction with recommendation results. Traditional recommendation mechanism (TRM) is b...

Across the nervous system, certain population spiking patterns are observed far more frequently than others. A hypothesis about this structure is that these collective activity patterns function as population codewords-collective modes-carrying information distinct from that of any single cell. We investigate this phenomenon in recordings of ∼150 retinal ganglion cells, the retina's output. We ...

In the global economy, knowledge has become a key asset in organizations; thus, Knowledge Management (KM) has emerged as a major issue that managers must deal with. However, implementing KM is becoming more complicated. Practitioners must assess complex and confusing situations, initiate KM, identify the causal relationships between problems, make appropriate decisions, and guarantee that the r...

A large number of studies have evaluated the association of hs-C-reactive protein with atherosclerosis and coronary heart disease (CHD) in mechanistic, genetic, population-based studies, as well as clinical trials. This paper reviews the collective evidence to determine if hs-C-reactive protein is part of the causal pathway of atherosclerosis and CHD or whether it is a bystander.

the concept of teacher efficacy has received significant attention in educational contexts in the recent years and has been empirically probed at 2 levels: individual teacher efficacy and collective teacher efficacy. having their origins in the social cognitive theory, teacher and collective efficacy perceptions are quite distinct constructs, each affecting educational decisions and student ach...

Intrinsic-signal optical imaging was used to evaluate relationships of domains of neurons in middle temporal visual area (MT) selective for stimulus orientation and direction-of-motion. Maps of activation were elicited in MT of owl monkeys by gratings drifting back-and-forth, flashed stationary gratings and unidirectionally drifting fields of random dots. Drifting gratings, typically used to re...
