The Influence of Signaling on the Disfluency Effect in Multimedia Learning

Do students learn better with texts that are slightly harder-to-read (i.e., disfluent)? Previous research has yielded conflicting findings. The present study identified the boundary condition that determines when disfluent texts benefit learning. We used eye-tracking to examine the joint influence of text legibility (fluent vs. disfluent) and signaling (signaling vs. non-signaling) on multimedia learning. The results revealed that both disfluent text and signaling led to better transfer test performance, and there was also an interaction between them. Specifically, the disfluent text led to better learning outcomes with or without signaling; however, in the fluent text condition, only signaling facilitated learning. Eye movement analyses indicated that signaling guided learners to pay more attention to important content in the learning materials. The current results suggest that signaling can enhance individuals’ perceived fluency or familiarity to the material and guide the attention during multimedia learning, and the positive impact of disfluency on multimedia learning seems to be more stable and ubiquitous. We discuss these under the framework of disfluency effect and attention-guiding effect.

Influence of Animation- Versus Text-Based Delivery of a Web-Based Computer-Tailored Smoking Cessation Intervention on User Perceptions

Computer-tailored (CT) digital health interventions have shown to be effective in obtaining behaviour change. Yet, user perceptions of these interventions are often unsatisfactory. Traditional CT interventions rely mostly on text-based feedback messages. A way of presenting feedback messages in a more engaging manner may be the use of narrated animations instead of text. The goal of this study was to assess the effect of manipulating the mode of delivery (animation vs. text) in a smoking cessation intervention on user perceptions among smokers and non-smokers. Smokers and non-smokers (N = 181) were randomized into either the animation or text condition. Participants in the animation condition assessed the intervention as more effective (ηp2 = .035), more trustworthy (ηp2 = .048), more enjoyable (ηp2 = .022), more aesthetic (ηp2 = .233), and more engaging (ηp2 = .043) compared to participants in the text condition. Participants that received animations compared to text messages also reported to actively trust the intervention more (ηp2 = .039) and graded the intervention better (ηp2 = .056). These findings suggest that animation-based interventions are superior to text-based interventions with respect to user perceptions.

Sobolev–Kantorovich inequalities under CD(0,∞) condition

We refine and generalize several interpolation inequalities bounding the [Formula: see text] norm of a probability density with respect to the reference measure [Formula: see text] by its Sobolev norm and the Kantorovich distance to [Formula: see text] on a smooth weighted Riemannian manifold satisfying [Formula: see text] condition.

Discourse, Figure, d’après Lyotard.

The presence of the written element in cinema goes back to the early silent movies era, to express meanings that were not enough comprehensible just through images. The use of text charts as means to support and to implement narrative almost invariable consisted of black cards with centered white type (rarely the opposite, i.e., black type on white boards), occasionally utilizing graphic features as ornaments.These letterings inserted between scenes, either before or after to which they referred, sometimes had a deranged narrative effect because of interrupting the action flow. But words, when added to the cinematographic image, can indeed communicate certain abstract concepts such as date time lapse, local; evince characters speeches; describe some action not performed in the movie.This paper aims to investigate the change of status of the written element as an accessory apparatus to a central and structural element of the movie, specifically in the experimental and avant-garde cinema, considering Marcel Duchamp’s Anémic Cinéma (1926) its inaugural example.The incorporation of textual elements can be understood within the very process of the visual arts in the first decades of the twentieth century since Braque’s Gueridon (1913) and Picasso’s Bottle of Vieux Marc, Glass, Guitar and Newspaper (1913) through the Cubist and the Dada conceptual and formal strategies.The Conceptual art of the sixties and seventies permeates expressions of film experimentalism that will be analyzed for its use of text condition, where Michael Snow’s So this is, already in early 80ies (1982) is to be highlighted.

Fish Tales: How Narrative Modality, Emotion, and Transportation Influence Support for Sustainable Aquaculture

Considerable research suggests narrative persuasion’s attitudinal and behavioral effects in health and environmental contexts. Whether the format of narrative presentation influences these effects, however, remains unclear. We use an online experiment ( N = 2,225), comparing text and video conditions, to evaluate how exposure to narrative influences transportation, emotions, and risk-benefit perceptions and, in turn, how such perceptions affect attitudes and behavioral intentions toward sustainable aquaculture. Consistent with prior research, the text condition was more transporting than the video. Further, a serial mediation model shows transportation as leading to lower risk perception, higher benefit perception, and higher aquaculture support.

An electrohydrodynamic (EHD) printing method with nanosilver ink for flexible electronics

In this paper, the electrohydrodynamic (EHD) printing method for the flexible electronics with nanosilver ink was studied. The effect of DC voltage and air pressure on the printed nanosilver line was experimentally researched on the printing system. The necessary working voltage was above 600 V DC voltage, and when the voltage reached 1100 V, the line width increased from [Formula: see text] to [Formula: see text]. The air supply of [Formula: see text] resulted an obviously larger width than that of [Formula: see text], but the printing process was unstable on the [Formula: see text] condition. The EHD printing was applied to realize nanosilver ink line ranged from [Formula: see text] to [Formula: see text] and a kind of antenna pattern for radio frequency identification devices (RFID) was fabricated. This kind of EHD printing method has the advantages of high flexibility and printing resolution and shows potential prospects in the field of flexible electronics.

Conformal Ricci soliton and geometrical structure in a perfect fluid spacetime

In this paper, we studied the geometrical aspects of a perfect fluid spacetime in terms of conformal Ricci soliton and conformal [Formula: see text]-Ricci soliton with torse-forming vector field [Formula: see text]. Condition for the conformal Ricci soliton to be steady, expanding or shrinking are also given. In particular case, when the potential vector filed [Formula: see text] of the soliton is of gradient type, we derive, from the conformal [Formula: see text]-Ricci soliton equation, a Laplacian equation.

Nearly cosymplectic manifolds with nullity conditions

In this paper, we study the geometry and topology of [Formula: see text]-Ricci solitons satisfying Ricci-semisymmetry condition, [Formula: see text] condition and finally Einstein-semisymmetry condition on nearly Kenmotsu manifolds.

User Perception of Situated Product Recommendations in Augmented Reality

Augmented reality (AR) interfaces increasingly utilize artificial intelligence systems to tailor content and experiences to the user. We explore the effects of one such system — a recommender system for online shopping — which allows customers to view personalized product recommendations in the physical spaces where they might be used. We describe results of a [Formula: see text] condition exploratory study in which recommendation quality was varied across three user interface types. Our results highlight potential differences in user perception of the recommended objects in an AR environment. Specifically, users rate product recommendations significantly higher in AR and in a 3D browser interface, and show a significant increase in trust in the recommender system, compared to a web interface with 2D product images. Through semi-structured interviews, we gather participant feedback which suggests AR interfaces perform better due to their ability to view products within the physical context where they will be used.
