Cross-sectional study, carried out at the outpatient clinic of an oncology hospital. Data were collected from 88 caregivers of cancer patients using the Caregiver General Comfort Questionnaire (GCQ) to assess the caregivers' comfort. The caregivers' GCQ score mean was 203.9; better comfort scores was associated with age, care time and current occupation; positive aspects of comfort were related...

respirators are commonly used to protect workers against workplace airborne contaminants, but this equipment may become a safety hazard by creating discomfort, disorientation and postural instability. although postural stability is critical to workers, especially those working near moving objects or on surfaces where a loss of balance may become life threatening, little attention has been given...

At the level of individual neurons. catecholamine release increases the responsivity of cells to excitatory and inhibitory inputs. We present a model of catecholamine effects in a network of neural-like elements. We argue that changes in the responsivity of individual elements do not affect their ability to detect a signal and ignore noise. However. the same changes in cell responsivity in a ne...

This work aims at validating a new statistical index (Weighted Pressure Comfort Loss, WPCL) for seat comfort assessment. The validation is carried out by deepening the relationship between subjective comfort evaluations and objective measures of seat comfort and comparing, from an engineering standpoint, the new index with the pressure peak which is currently one of the most used indexes for se...

In this paper, I examine the charge that Gopnik and Meltzoff's 'Child as Scientist' program, outlined and defended in their 1997 book Words, Thoughts and Theories is vitiated by a form of 'cognitive individualism' about science. Although this charge has often been leveled at Gopnik and Meltzoff's work, it has rarely been developed in any detail. I suggest that we should distinguish between two ...

Correspondence to: D. Levinson (e-mail: [email protected]) Abstract. This paper examines the full costs, defined as the sum of private and social costs, of a high-speed rail system proposed for a corridor connecting Los Angeles and San Francisco in California. The full costs include infrastructure, fleet capital and operating expenses, the time users spend on the system, and the soc...

Collaboration in research continuously gains importance. Recent developments in online collaboration technology, namely social research network sites (SRNS), specifically aim to support research collaboration. SRNS allow researchers to present themselves, to network, to communicate, and to collaborate. Acceptance of this technology by researchers has received little academic attention, a void t...

An important problem in bandwidth allocation and reservation over a communication link is to estimate the traffic bit rate in that link. This can be done by using specific tools for measurements of the traffic bit rate. However, the obtained measures are affected by some noise. Moreover, one might be interested in future traffic forecasting, when a prediction is needed. In this paper, an iterat...
