What Factors Facilitate Good Learning Experiences in Clinical Studies in Nursing: Bachelor Students’ Perceptions

2013

Published version of an article from the journal:ISRN Nursing. Also available from the publisher: http://dx.doi.org/10.1155/2013/628679 Clinical studies constitute 50% of the bachelor program in nursing education in Norway, and the quality of these studies may be decisive for the students’ opportunities to learn and develop their professional competences. The aim of this study was to explore what bachelor students’ in nursing perceived to be important for having good learning experiences in clinical studies. Data was collected in a focus group interview with eight nursing students who were in the last year of the educational program. The interview was transcribed verbatim, and qualitative c…

Great Minds Think Alike? Spatial Search Processes Can Be More Idiosyncratic When Guided by More Accurate Information.

2022

Existing research demonstrates that pre-decisional information sampling strategies are often stablewithin a given person while varying greatly across people. However, it remains largely unknown whatdrives these individual differences, that is, why in some circumstances we collect information moreidiosyncratically. In this brief report, we present a pre-registered online study of spatial search. Usinga novel technique that combines machine-learning dimension reduction and sequence alignment algo-rithms, we quantify the extent to which the shape and temporal properties of a search trajectory areidiosyncratic. We show that this metric increases (trajectories become more idiosyncratic) when a p…

Imaging Quality of Bifocal Piggyback Intraocular Lens versus ReSTOR and TECNIS Multifocal Lenses

2009

Purpose The imaging quality provided by a piggyback integrated by a monofocal intraocular lens (IOL) + a bifocal IOL of zero power and +3.75 diopters of addition is compared with the optics quality of a simple multifocal IOL of the same power and addition. Methods The imaging quality was evaluated by determining the modulation transfer function (MTF), using an artificial eye simulating in vivo conditions of the anterior chamber, including an artificial cornea and a wet cell containing physiologic solution where the IOL was positioned. The MTFs of the bifocal piggyback for near and distance vision were measured, with pupil diameters of 3 and 5 mm, and compared with the MTFs of an equivalent …

Why Cortices ? Neural Computation in the Vertebrate Visual System

1989

We propose three high level structural principles of neural networks in the vertebrate visual cortex and discuss some of their computational implications for early vision: a) Lamination, average axonal and dendritic domains, and intrinsic feedback determine the spatio-temporal interactions in cortical processing. Possible applications of the resulting filters include continuous motion perception and the direct measurement of high-level parameters of image flow, b) Retinotopic mapping is an emergent property of massively parallel connections. With a local intrinsic operation in the target area, mapping combines to a space-variant image processing system as would be useful in the analysis of …

Why Cortices? Neural Networks for Visual Information Processing

1989

Neural networks for the processing of sensory information show remarkable similarities between different species and across different sensory modalities. As an example, cortical organization found in the mamalian neopallium and in the optic tecta of most vertebrates appears to be equally appropriate as a substrate for visual, auditory, and somatosensory information processing. In this paper, we formulate three structural principles of the vertebrate visual cortex that allow to analyze structure and function of these neural networks on an intermediate level of complexity. Computational applications are taken from the field of early vision. The proposed principles are: (a) Average anatomy, i …

Perceptions, attitudes and ethical valuations: The ambivalence of the public image of biotechnology in Spain

2000

This paper analyzes the study of the public perception of biotechnology, comparing different studies made on the European and the Spanish national levels. It aims at testing the applicability of these kinds of studies, and describes some of their limits. The analysis shows clear ambivalence in the public response to distinct applications of this technology, pointing out the crucial differences between general moral valuation and attitude towards specific products. Taking into account this difference appears fundamental for the design of future perception studies able to more accurately reflect public understanding.

Gaze position reveals impaired attentional shift during visual word recognition in dysfluent readers

2014

Effects reflecting serial within-word processing are frequently found in pseudo- and non-word recognition tasks not only among fluent, but especially among dyslexic readers. However, the time course and locus of these serial within-word processing effects in the cognitive hierarchy (i.e., orthographic, phonological, lexical) have remained elusive. We studied whether a subject’s eye movements during a lexical decision task would provide information about the temporal dynamics of serial within-word processing. We assumed that if there is serial within-word processing proceeding from left to right, items with informative beginnings would attract the gaze position and (micro-)saccadic eye movem…

Nurses' perception of the oncology patient's death: a qualitative study

2021

Death is one of the basic theme with which nurses are faced, and for which it is hard for them to prepare deeply and sincerely. The difficulties in handling the emotional burden can cause them to develop negative feelings towards life and clinical practice, so that it affects their caregiving capacity and the quality of care provided.To explore nurses' perceptions facing the death of a hospitalized oncology patient.Qualitative phenomenological study. The sample of nurses was recruited at IRCCS (Scientific Institute for Research and Healthcare) in Rome, a hospice in Latina and a hospice in Rieti. The data were collected by means of focus groups. The semi-structured interviews featuring three…
