The staking of containers on ideal locations within the yard is a tactical decision that affects productivity container terminals. goal to improve posterior loading and retrieval operations, get better use terminal resources. In this paper, we study how allocate storage space for outbound in A two-phase methodological framework proposed. first phase groups into clusters similar operational cond...

When processing complex visual input, human observers sequentially allocate their attention to different subsets of the stimulus. What are the mechanisms and strategies that guide this selection process? We investigated the influence of various stimulus features on human overt attention--that is, attention related to shifts of gaze with natural color images and modified versions thereof. Our ex...

What is the subject here? The aim is to gain control of this medium, mostly so as to be able to make those faces, my main proving ground. And the medium itself —is what? Clearly it involves folding curves (in, as it happens, rectangles of brown wrapping paper sprayglued to thick aluminum foil). Now curve-folding, as is known, creates surfaces that won’t lie flush to each other, or “open folds”;...

We study the integrated operational and financial hedging decisions faced by a global firm who sells to both home and foreign markets. Production occurs either at a single facility located in one of the markets or at two facilities, one in each market. The company has to invest in capacity before the selling season starts when the demand in both markets and the currency exchange rate are uncert...

Fluid (or Hybrid) Petri Nets are Petri net based models with two classes of places: discrete places that carry a natural number of distinct objects (tokens), and fluid places that hold a positive amount of fluid, represented by a real number. With respect to previous formulations, the FSPN model presented in this paper, is augmented with a new primitive, called flush-out arc. A flush-out arc co...

Learning how to allocate attention properly is essential for success at many categorization tasks. Advances in our understanding of learned attention are stymied by a chicken-and-egg problem: there are no theoretical accounts of learned attention that predict patterns of eye movements, making data collection difficult to justify, and there are not enough datasets to support the development of a...

Threatening stimuli have been shown to preferentially capture attention using a range of tasks and measures. However, attentional bias to threat has not typically been found in unselected individuals using behavioral measures in the dot-probe task, one of the most common ways of examining attention to threat. The present study leveraged event-related potentials (ERPs) in conjunction with behavi...

Across different studies, patients with temporal lobe epilepsy (TLE) demonstrate impairments on numerous measures of attentional control that are classically associated with frontal lobe functioning. One aspect of attentional control that has not been examined in TLE is the ability to execute two modality-specific tasks concurrently. We sought to examine the status of dual-task coordination in ...

We show that firm-level short interest predicts negative returns for individual stocks during economic expansions, while aggregate short interest predicts negative market returns during recessions. Viewing short sellers as informed traders, these findings are consistent with Kacperczyk, Van Nieuwerburgh, and Veldkamp’s (2016) model in which rational yet cognitively constrained traders optimally...
