A Tale of Two Sources in Native Advertising: Examining the Effects of Source Credibility and Priming on Content,Organizations, and Media Evaluations

In the strategic communication field, native advertising has been hailed as the next big trend. However, this type of marketing technique may negatively affect the perceptions of brands as well as media outlets that provide such content due to its obscurity of persuasive intent and ambiguity of the content source. The current study examined these issues by conducting a 2 (priming: presence vs. absence) × 2 (media credibility: high vs. low) × 2 (corporate credibility: high vs. low) factorial between-subjects experiment. A total of 500 participants recruited from Amazon Mechanical Turk completed the online experiment. Findings suggested that priming of native advertising information would significantly improve users’ ad recognition and change their content perception. In addition, a series of three-way interaction effects suggested that the interaction between the two types of source credibility (media and corporate) tend to work as a function of priming of native advertising information, which could completely change individuals’ perception of the ad content and evaluation of the media source in the future, but not their future corporate evaluation. Important theoretical as well as practical implications have also been discussed in this article

Directional torsion and temperature discrimination based on a multicore fiber with a helical structure

We propose and experimentally demonstrate a directional torsion sensor based on a Mach-Zehnder interferometer formed in a multicore fiber (MCF) with a ~570-μm-long helical structure (HS). The HS was fabricated into the MCF by simply pre-twisting and then heating with a CO2 laser splicing system. This device shows the capability of directional torsion measurement from −17.094 rad/m to 15.669 rad/m with the sensitivity of ~0.118 nm/(rad/m). Moreover, since the multiple interferences respond differently to torsion and temperature simultaneously, the temperature cross-sensitivity of the proposed sensor can be eliminated effectively. Besides, the sensor owns other merits such as easy fabrication and good mechanical robustness.NRF (Natl Research Foundation, S’pore)MOE (Min. of Education, S’pore)Published versio

Nacre-Templated Synthesis of Highly Dispersible Carbon Nanomeshes for Layered Membranes with High-Flux Filtration and Sensing Properties

Marine shells not only represent a rapidly accumulating type of fishery wastes but also offer a unique sort of hybrid nanomaterials produced greenly and massively in nature. The elaborate “brick and mortar” structures of nacre enabled the synthesis of carbon nanomeshes with <1 nm thickness, hierarchical porosity, and high specific surface area through pyrolysis, in which two-dimensional (2D) organic layers served as the carbonaceous precursor and aragonite platelets as the hard template. Mineral bridges within 2D organic layers templated the formation of mesh pores of 20–70 nm. In contrast to other hydrophobic carbon nanomaterials, these carbon nanomeshes showed super dispersibility in diverse solvents and thus processability for membranes through filtration, patterning, spray-coating, and ink-writing. The carbon membranes with layered structures were capable of serving not only for high-flux filtration and continuous flow absorption but also for electrochemical and strain sensing with high sensitivity. Thus, utilization of marine shells, on one hand, relieves the environmental concern of shellfish waste, on the other hand, offers a facile, green, low-cost, and massive approach to synthesize unique carbon nanomeshes alternative to graphene nanomeshes and applicable in environmental adsorption, filtration, wearable sensors, and flexible microelectronics

Highly sensitive strain sensor based on helical structure combined with Mach-Zehnder interferometer in multicore fiber

Optical fiber sensors for strain measurement have been playing important roles in structural health monitoring for buildings, tunnels, pipelines, aircrafts, and so on. A highly sensitive strain sensor based on helical structures (HSs) assisted Mach-Zehnder interference in an all-solid heterogeneous multicore fiber (MCF) is proposed and experimentally demonstrated. Due to the HSs, a maximum strain sensitivity as high as −61.8 pm/με was experimentally achieved. This is the highest sensitivity among interferometer-based strain sensors reported so far, to the best of our knowledge. Moreover, the proposed sensor has the ability to discriminate axial strain and temperature, and offers several advantages such as repeatability of fabrication, robust structure and compact size, which further benefits its practical sensing applications.MOE (Min. of Education, S’pore)Published versio
