When Intrusive Can Be Likable: Product Placement Effects on Multitasking Consumers

Using movie scenes, this study examines how multitasking by viewers influences the product-plot integration effect. Findings indicate that multitasking dampens a well-integrated placement\u27s brand-enhancing effect and mitigates an intrusive placement\u27s brand-damaging effect. Well-integrated placement produces an assimilation effect, leading to convergence of viewers\u27 attitudes toward the placed versus competing brands, while intrusive placement triggers a contrast effect that results in divergence of these attitudes. Among single-tasking viewers, the boomerang effect of an intrusive placement decreases the favorability of the placed brand and increases the favorability of the not-shown competitor. The opposite is true among multitasking viewers, however

Text versus pictures in advertising: effects of psychological distance and product type

The authors examine effects of marketing messages that use text or pictures for advertising durable or nondurable products appealing to consumers’ perceptions of close versus far psychological distance. In three studies, ads featuring text (pictures) evoke more favourable attitudes and purchase intentions toward products to be purchased in the distant (close) future or at a distant (close) location. In addition, ads featuring text (pictures) evoke more favourable attitudes and purchase intentions for durable (nondurable) goods. The research shows that marketers will be most persuasive if they ensure congruence among message formats, product types, and psychological distance

Cancel Anytime! How Easy Cancellation Options Enhance Purchase Intentions for Services that Require Long-Term Commitments

The authors recognize that an uncertain environment associated with prolonged pandemic conditions have made consumers reluctant to make long-term contractual commitments in various retail contexts. Hypothesizing that retailers might offer cancellation options to motivate consumers to undertake long-term commitments, the authors conduct two studies in which cancellation messages accompany ads for an online language course and a gym membership. Findings indicate that retailers can alleviate the pressures associated with long-term commitment decisions and can heighten purchase intentions by providing cancel options for consumers who register for services requiring long-term but not short-term commitments. Perceived goal achievability is identified as an underlying mechanism that mediates the effects

Local Metric Learning for Off-Policy Evaluation in Contextual Bandits with Continuous Actions

We consider local kernel metric learning for off-policy evaluation (OPE) of deterministic policies in contextual bandits with continuous action spaces. Our work is motivated by practical scenarios where the target policy needs to be deterministic due to domain requirements, such as prescription of treatment dosage and duration in medicine. Although importance sampling (IS) provides a basic principle for OPE, it is ill-posed for the deterministic target policy with continuous actions. Our main idea is to relax the target policy and pose the problem as kernel-based estimation, where we learn the kernel metric in order to minimize the overall mean squared error (MSE). We present an analytic solution for the optimal metric, based on the analysis of bias and variance. Whereas prior work has been limited to scalar action spaces or kernel bandwidth selection, our work takes a step further being capable of vector action spaces and metric optimization. We show that our estimator is consistent, and significantly reduces the MSE compared to baseline OPE methods through experiments on various domains

The impact of communication information on the perceived threat of COVID-19 and stockpiling intention

This article investigates the role of diverse nudging communication strategies on perceived threat and stockpiling intention. Across three studies, the authors examined the various effects of “nudging” on consumer behavior. Study 1 demonstrates that a commonly used picture has a stronger impact on perceived threat than a less frequently exposed picture regardless of its accuracy. Study 2 shows that the perceived threat of COVID-19, in terms of severe health consequences, is lower when using an indirect (vs. direct) explanation of the virus, as well as when reducing the amount of information about the virus. Study 3 investigates the impact of salient negative information and childhood socioeconomic status (SES). Findings reveal that negative information about deaths associated with the virus increases the level of perceived threat and stockpiling intention, especially among people of low childhood SES

Down-Regulation of NF-κB Target Genes by the AP-1 and STAT Complex during the Innate Immune Response in Drosophila

The activation of several transcription factors is required for the elimination of infectious pathogens via the innate immune response. The transcription factors NF-κB, AP-1, and STAT play major roles in the synthesis of immune effector molecules during innate immune responses. However, the fact that these immune responses can have cytotoxic effects requires their tight regulation to achieve restricted and transient activation, and mis-regulation of the damping process has pathological consequences. Here we show that AP-1 and STAT are themselves the major inhibitors responsible for damping NF-κB–mediated transcriptional activation during the innate immune response in Drosophila. As the levels of dAP-1 and Stat92E increase due to continuous immune signaling, they play a repressive role by forming a repressosome complex with the Drosophila HMG protein, Dsp1. The dAP-1–, Stat92E-, and Dsp1-containing complexes replace Relish at the promoters of diverse immune effector genes by binding to evolutionarily conserved cis-elements, and they recruit histone deacetylase to inhibit transcription. Reduction by mutation of dAP-1, Stat92E, or Dsp1 results in hyperactivation of Relish target genes and reduces the viability of bacterially infected flies despite more efficient pathogen clearance. These defects are rescued by reducing the Relish copy number, thus confirming that mis-regulation of Relish, not inadequate activation of dAP-1, Stat92E, or Dsp1 target genes, is responsible for the reduced survival of the mutants. We conclude that an inhibitory effect of AP-1 and STAT on NF-κB is required for properly balanced immune responses and appears to be evolutionarily conserved

NeBula: Team CoSTAR's robotic autonomy solution that won phase II of DARPA Subterranean Challenge

This paper presents and discusses algorithms, hardware, and software architecture developed by the TEAM CoSTAR (Collaborative SubTerranean Autonomous Robots), competing in the DARPA Subterranean Challenge. Specifically, it presents the techniques utilized within the Tunnel (2019) and Urban (2020) competitions, where CoSTAR achieved second and first place, respectively. We also discuss CoSTAR¿s demonstrations in Martian-analog surface and subsurface (lava tubes) exploration. The paper introduces our autonomy solution, referred to as NeBula (Networked Belief-aware Perceptual Autonomy). NeBula is an uncertainty-aware framework that aims at enabling resilient and modular autonomy solutions by performing reasoning and decision making in the belief space (space of probability distributions over the robot and world states). We discuss various components of the NeBula framework, including (i) geometric and semantic environment mapping, (ii) a multi-modal positioning system, (iii) traversability analysis and local planning, (iv) global motion planning and exploration behavior, (v) risk-aware mission planning, (vi) networking and decentralized reasoning, and (vii) learning-enabled adaptation. We discuss the performance of NeBula on several robot types (e.g., wheeled, legged, flying), in various environments. We discuss the specific results and lessons learned from fielding this solution in the challenging courses of the DARPA Subterranean Challenge competition.The work is partially supported by the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration (80NM0018D0004), and Defense Advanced Research Projects Agency (DARPA)

E-WOM Messaging on Social Media: social ties, temporal distance, and message concreteness

Purpose The purpose of this paper is to explore the intentions to share electronic word-of-mouth (E-WOM) messages on social media websites depending on tie strength, perceptions of temporal distance and the concreteness of promotional messages. Design/methodology/approach A 2×2×2 mixed design is used. Temporal distance (near vs distant) and message concreteness (text vs picture) are between-subjects factors; sharing intentions (close friends vs general public) is a within-subjects factor. Findings Findings indicate that consumers are more likely to share promotional messages with their strong rather than weak ties. If they perceive that purchases will occur soon, concrete promotional messages will more strongly motivate them to share the message with their friends. However, if they perceive that purchases will occur in the distant future, abstract messages are more motivating. The difference occurs because construal-level theory is more effective among strong E-WOM ties. Originality/value By studying senders’ perspectives, the authors make a new theoretical and practical contribution to the emerging literature on E-WOM communication. Specifically, the authors show how senders are persuaded to share information with their strong- or weak-tie audiences according to the concreteness of a message and temporal distance. The authors add construal-level theory and advertising message processing to the domain of E-WOM and social ties research

Different Routes to Judgment Formation

This article identifies and reviews the three routes to judgment - elaborative, peripheral, and automatic processing - and their antecedents and consequences in the context of advertising effects. The mechanism of these routes are illustrated through the consideration of the roles of product, media, programming context, mood, individual differences, cognitive load, and other variables that may influence the way a judgment is formed. The multiple roles of affect in each of these types of judgment-formation processes are also discussed. We concluded that different types of judgment process are determined by product related factors, media related factors, and consumer related factors. Further, the present study suggests the impact of affect on three types of judgment processes that consequently lead to consumers\u27 attitudes. Based on the findings of the study, theoretical applications for future studies are recommended
