Choice of communication media is an important topic in Information Systems research. To complement the prevailing research which focuses on the effective delivery of message through communication media, this research regards communication as a way to accomplish social exchanges. Because communication media vary in their capacity to deliver nonverbal cues, they vary in their capacity to produce ...

Capacity choice or expansion, whether organic or via mergers and acquisitions, creates firms of widely varying scales. The ex-post profitability of such a transformed firm relative to its original size will typically be evaluated on ratio (rate) measures like earnings per share or profits to asset ratio, as such are the only meaningful ways to compare profitability of firms of substantially dif...

OBJECTIVES To investigate capacity to consent to medical treatment (competency) in cognitively impaired patients with PD. BACKGROUND Although competency has been studied empirically in patients with cortical dementia (AD), no empirical studies have examined competency in patients with PD or other subcortical neurodegenerative disorders. METHODS Patients with PD with cognitive impairment (n ...

OBJECTIVE To examine the contribution of neuropsychological test performance to treatment decision-making capacity in community volunteers with mild to moderate dementia. METHODS The authors recruited volunteers (44 men, 44 women) with mild to moderate dementia from the community. Subjects completed a battery of 11 neuropsychological tests that assessed auditory and visual attention, logical ...

Decision making theory in general, and mental models in particular, associate judgment and choice. Decision choice follows probability estimates and errors in choice derive mainly from errors in judgment. In the studies reported here we use the Monty Hall dilemma to illustrate that judgment and choice do not always go together, and that such a dissociation can lead to better decision-making. Sp...

We present two capacity choice scenarios for the socially optimal location of facilities with fixed servers, stochastic demand and congestion. Walk-in health clinics, motor vehicle inspection stations, automobile emissions testing stations, and internal service systems are motivating examples of such facilities. The choice of locations for such facilities influences not only distances for users...

Previous studies have demonstrated that working memory capacity plays a central role in delay discounting in people with externalizing psychopathology. These studies used a hyperbolic discounting model, and its single parameter-a measure of delay discounting-was estimated using the standard method of searching for indifference points between intertemporal options. However, there are several pro...

Accounts of decision-making have long posited the operation of separate, competing valuation systems in the control of choice behavior. Recent theoretical and experimental advances suggest that this classic distinction between habitual and goal-directed (or more generally, automatic and controlled) choice may arise from two computational strategies for reinforcement learning, called model-free ...

Disk drives are now available with capacity and price per capacity comparable to (and in some cases better than) nearline tape systems. Given disks' superior performance , density and maintainability characteristics, it seems likely that disks will soon overtake tapes as the backup medium of choice. In this paper, we outline the potential advantages of a backup system composed of high-capacity ...

The signaling capacity of traces on the popular PCB dielectric.material FR4 is under-utilized today by at least one order of magnitude through the choice of pre-coding, pulseshaping, equalization, and receiver architecture. This paper determines the channel capacity of FX4 traces of various length in the presence of noise and crosstalk, and explores capacity limits based on signaling schemes su...
