Implementing a Digital Strategy:Learning from the Experience of Three Digital Transformation Projects
The rapid growth of digital technologies and the extraordinary amount of data that devices and applications collect each day are increasingly driving companies to radically transform the business architecture through which they create and appropriate value. However, companies may fail to extract value from digital transformation due to the disconnection between strategy formulation and strategy implementation. Through the analysis of three case studies of firms that digitally transformed their business - namely ABB, CNH Industrial, and Vodafone -, this article presents a framework than can help companies implement their digital transformation strategy and thereby renovate their business model
An impaired attentional dwell time after parietal and frontal lesions related to impaired selective attention not unilateral neglect.
The attentional blink, a measure of the temporal dynamics of visual processing, has been documented to be more pronounced following brain lesions that are associated with visual neglect. This suggests that, in addition to their spatial bias in attention, neglect patients may have a prolonged dwell time for attention. Here the attentional dwell time was examined in patients with damage focused on either posterior parietal or frontal cortices. In three experiments, we show that there is an abnormally pronounced attentional dwell time, which does not differ in patients with posterior parietal and with frontal lobe lesions, and this is associated with a measure of selective attention but not with measures of spatial bias in selection. These data occurred both when we attempted to match patients and controls for overall differences in performance and when a single set stimulus exposure was used across participants. In Experiments 1 and 2, requiring report of colour-form conjunctions, there was evidence that the patients were also impaired at temporal binding, showing errors in feature combination across stimuli and in reporting in the correct temporal order. In Experiment 3, requiring only the report of features but introducing task switching led to similar results. The data suggest that damage to a frontoparietal network can compromise temporal selection of visual stimuli; however, this is not necessarily related to a deficit in hemispatial visual attention but it is to impaired target selection. We discuss the implications for understanding visual selection
Luminosity - a perceptual "feature" of light-emitting objects
AbstractLight-emitting objects are perceived as qualitatively different from light-reflecting objects, and the two categories elicit different cortical activity. However, it is unclear whether object luminosity is treated as an independent visual feature, comparable to orientation, motion or colour. Visual search tasks revealed that light-emitting targets led to efficient search when presented with light-reflecting distractors of similar luminance, but this efficiency was induced by the presence of luminance gradients producing the percept of luminosity rather than by luminosity itself. This implies that luminance gradients (not object luminosity) are encoded as features, questioning the existence of specific sensory mechanisms to detect light-emitting objects

Theoretical Study on the Excited Electronic States of CHCl: Application to Photodissociation at 193 nm
We
present herein a high-level ab initio study on the electronic
excited states of CHCl using the internally contracted multireference
configuration interaction method including Davidson correction (icMRCI+Q).
A total of 13 electronic states with energy of up to 7 eV have been
investigated. The vertical transition energies, oscillator strengths,
electron configurations, and transitions of the electronic states
of CHCl have been calculated at the icMRCI+Q/aug-cc-pvÂ(5+d)ÂZ level.
The potential energy curves of the electronic states have been studied
along the H–C–Cl angle, the C–H bond length,
and the C–Cl bond length, respectively. Our theoretical study
has provided comprehensive information for understanding the interaction
and the behavior of the electronic excited states of CHCl. In particular,
the excited state involved in the 193 nm photodissociation as well
as the corresponding dissociation dynamics have been discussed on
the basis of our calculation results. The present study should shed
more light on the photochemistry of CHCl in the ultraviolet region
