INDIRECT PERSUASION IN ADVERTISING: How Consumers Process Metaphors Presented in Pictures and Words

Abstract: Indirect persuasion attempts are common in magazine advertisements. Although the use of an indirect claim presumably offers some advantage to an advertiser, as yet, little is known about how consumers process different types of indirect claims. We develop the proposition that when consumers are presented with an indirect metaphorical claim, they become more receptive to multiple positive inferences about the advertised brand. In addition, when the indirect metaphorical claim takes the form of a picture, consumers are more likely to spontaneously generate such positive inferences at the time of ad exposure. These ideas are supported in an experiment using response latency data. Because many of the inferences examined in this study could be considered misleading if claimed directly, the paper concludes with a discussion of the public policy implications of the findings.

A review of the occurrence and fate of naphthenic acids in aquatic environments.

Abstract: Naphthenic acids are comprised of a large collection of saturated aliphatic and alicyclic carboxylic acids found in hydrocarbon deposits (petroleum, oil sands bitumen, and crude oils) Naphthenic acids enter surface water systems primarily through effluent discharge, but also through groundwater mixing and erosion of riverbank oil deposits Of the possible environmental receptors (ie, air, soil, and water), the most significant is water Ambient levels of naphthenic acids in northern Alberta rivers in the Athabasca Oil Sands are generally below 1 mg L(-1) However, tailings pond waters may contain as high as 110 mg L(-1) The complexity of natural naphthenic acids in petroleum deposits poses an analytical challenge as reflected by the several techniques reported for quantitation of naphthenic acids in the environment Although naphthenic acids are known to be persistent biomarkers used in identification of oil source maturation, little is established regarding their relative degradation pathways in aquatic environments Published research related to the potential for microbiological degradation and adsorption to typical Athabasca Oil Sands soils reveal that naphthenic acids are likely to persist in the water column and, with prolonged exposure, accumulate in sediments However, other than a very general knowledge of environmental persistence, the occurrence and fate of naphthenic acids has been sparsely studied This article brings together some of those environmental persistence results, as well as detailed information regarding the origin of naphthenic acids in tailings ponds, chemistry and toxicological considerations, current analytical methods for aquatic sampling, and areas of future remediation research

Blockchain as a Service for IoT

Abstract: A blockchain is a distributed and decentralized ledger that contains connected blocks of transactions. Unlike other ledger approaches, blockchain guarantees tamper proof storage of approved transactions. Due to its distributed and decentralized organization, blockchain is beeing used within IoT e.g. to manage device configuration, store sensor data and enable micro-payments. This paper presents the idea of using blockchain as a service for IoT and evaluates the performance of a cloud and edge hosted blockchain implementation.

Properties of Fe-Organic Matter Associations via Coprecipitation versus Adsorption

Abstract: The association of organic matter (OM) with minerals is recognized as the most important stabilization mechanism for soil organic matter. This study compared the properties of Fe–OM complexes formed from adsorption (reaction of OM to postsynthesis ferrihydrite) versus coprecipitation (formation of Fe solids in the presence of OM). Coprecipitates and adsorption complexes were synthesized using dissolved organic matter (DOM) extracts from a forest little layer at varying molar C/Fe ratios of 0.3–25.0. Sample properties were studied by N2 gas adsorption, XRD, FTIR, Fe EXAFS, and STXM-NEXAFS techniques. Coprecipitation resulted in much higher maximum C contents (∼130 mg g–1 C difference) in the solid products than adsorption, which may be related to the formation of precipitated insoluble Fe(III)–organic complexes at high C/Fe ratios in the coprecipitates as revealed by Fe EXAFS analysis. Coprecipitation led to a complete blockage of mineral surface sites and pores with ≥177 mg g–1 C and molar C/Fe ratios ≥2....
