Using EEG to Examine the Role of Attention, Working Memory, Emotion, and Imagination in Narrative Transportation
This paper presents a study using encephalography (EEG) to investigate consumer responses to narrative videos in energy efficiency social marketing. The purpose is to assess the role of attention, working memory, emotion, and imagination in narrative transportation, and how these stages of narrative transportation are ordered temporally.
Design/methodology/approach
Consumers took part in an EEG experiment during which they were shown four different narrative videos to identify brain response during specific video segments.
Findings
The study found that during the opening segment of the videos, attention, working memory, and emotion were high before attenuating with some introspection at the end of this segment. During the story segment of the videos attention, working memory, and emotion were also high, with attention decreasing later on but working memory, emotion, and imagination being evident. Consumer responses to each of the four videos differed.
Practical implications
The study suggests that narratives can be a useful approach in energy efficiency social marketing. Specifically, marketers should attempt to gain focused attention and invoke emotional responses, working memory, and imagination to help consumers become narratively transported. The fit between story object and story-receiver should also be considered when creating consumer narratives.
Social implications
Policy makers, and organisations who wish to promote pro-social behaviours such as using energy efficiently, or eating healthily should consider using narratives.
Originality/value
This research contributes to theory by identifying brain response relating to attention, working memory, emotion, and imagination during specific stages of narrative transportation. The study considers the role of attention, emotion, working memory, and imagination during reception of stories with different objects, and how these may relate to consumers' narrative transportation
Qualité des pommes de terre : nouvelles méthodes d'évaluation calibrées sur l'analyse sensorielle
Quality of potatoes : new assessment methods calibrated by means of sensory analysis [frying index]. For the potato sector, raw material quality became an important criterium because it determines the type of use and the transformation ability of the tubers. It is now primordial to be able to identify the quality level of a share by reliable and objective methods. The qualitative criteria of potatoes are for the most estimated via sensory tests. During this survey, we measured several texture descriptors (desintegration, flouriness, granulation), the flesh colour, the after-cooking blackening susceptibility, the taste intensity and the after-frying coloration of the samples. In order to get rid of the human subjectivity, we studied the potentialities of near infrared spectrometry (NIRS) and of image analysis to predict or to measure these sensory behaviours. We observed high correlation between real values and values predicted by NIRS models, mainly for texture descriptors and flesh colour. Frying index prediction by NIRS is acceptable, but less precise than its measurement by image analysis
Ligamentous rupture of the ACL associated with dislocated fracture of the proximal tibial physis in a 12-year-old boy
BACKGROUND: Dislocated fracture of the proximal physeal plate of the tibia with or without metaphyseal fragment is rare in children. This unusual fracture classically excludes rupture of the anterior cruciate ligament due to the ligament's stability. A combination of both injuries has not been previously published in the literature. CASE PRESENTATION: The authors report the case of a 12-year-old boy who presented with a dislocated fracture (Salter-Harris II) of the proximal tibia combined with ligamentous rupture of the anterior cruciate ligament after a sporting accident
Nonlinear optical interactions in silicon waveguides
The strong nonlinear response of silicon photonic nanowire waveguides allows for the integration of nonlinear optical functions on a chip. However, the detrimental nonlinear optical absorption in silicon at telecom wavelengths limits the efficiency of many such experiments. In this review, several approaches are proposed and demonstrated to overcome this fundamental issue. By using the proposed methods, we demonstrate amongst others supercontinuum generation, frequency comb generation, a parametric optical amplifier, and a parametric optical oscillator

Coherent coupling between radio frequency, optical, and acoustic waves in piezo-optomechanical circuits
The interaction of optical and mechanical modes in nanoscale optomechanical
systems has been widely studied for applications ranging from sensing to
quantum information science. Here, we develop a platform for cavity
optomechanical circuits in which localized and interacting 1550 nm photons and
2.4 GHz phonons are combined with photonic and phononic waveguides. Working in
GaAs facilitates manipulation of the localized mechanical mode either with a
radio frequency field through the piezo-electric effect, or optically through
the strong photoelastic effect. We use this to demonstrate a novel acoustic
wave interference effect, analogous to coherent population trapping in atomic
systems, in which the coherent mechanical motion induced by the electrical
drive can be completely cancelled out by the optically-driven motion. The
ability to manipulate cavity optomechanical systems with equal facility through
either photonic or phononic channels enables new device and system
architectures for signal transduction between the optical, electrical, and
mechanical domains

A non-randomized comparison of gemcitabine-based chemoradiation with or without induction chemotherapy for locally advanced squamous cell carcinoma of the head and neck
<p>Abstract</p> <p>Background</p> <p>Concomitant chemotherapy and radiotherapy (chemoradiation; CRT) is the standard treatment for locoregionally advanced squamous cell carcinoma of the head and neck (LA-SCCHN). CRT improves local control and overall survival (OS) when compared to radiotherapy (RT) alone. Induction chemotherapy (IC) reduces the risk of distant metastases (DM) and improves OS by 5% with the use of cisplatin/infusional 5 fluorouracil (PF) in meta-analysis. Adding a taxane to PF in the IC regimen confers a better outcome. Sequential treatment (ST) of IC followed by CRT is therefore under active investigation in multiple phase III trials.</p> <p>Methods</p> <p>We compared the outcome of two cohorts of patients (pts) with LA-SCCHN treated at our institution with CRT (n = 27) or ST (n = 31), respectively. CRT consisted of GEM 100 mg/m<sup>2 </sup>weekly + conventional RT (70 Gy); ST consisted of the same CRT preceded by platinum-based IC.</p> <p>Results</p> <p>Response to IC: complete 8 (26%), partial 20 (65%), stable 1, progressive 1, not evaluable 1. Median follow up of the surviving pts: for CRT 73 months, for ST 51 months. Median time to distant metastasis (TDM) was for CRT 23.6 months, for ST not reached. Median OS was for CRT 20.2 months, for ST 40.2 months. Cox regression analysis, taking into account age, T and N stage and tumor site, showed a hazard ratio with ST of 1.190 for time to locoregional failure (p = 0.712), 0.162 for TDM (p = 0.002), and 0.441 for overall survival (OS) (p = 0.026).</p> <p>Conclusion</p> <p>TDM and OS were found significantly longer in the ST cohort without a reduced locoregional control. Notwithstanding the limitations of a non-randomized single-center comparison, the results are in line with very preliminary data of randomized comparisons suggesting an improved outcome with ST.</p
