Abstract The proliferation of mobile devices and the continuous development online technologies has led to an increasing variety channels, leaving customers with a choice channel alongside product, service, or retailer. Any attempt optimize customer experience engage in successful omnichannel management will require complete, multifaceted understanding processes around customers. To date, many existing studies multi- research have failed yield integrated, comprehensive synthesis factors...

Abstract The proliferation of smartphones, tablets and other digital devices in addition to traditional computers has transformed the Internet into a device‐mediated environment. While these provide immediate access similar sources, they differ significantly their characteristics, such as screen size, operation mode context use. As consequence, behaviours on along customer journey vary substantially depending device used. To summarize fast‐growing body research behaviour, systematic,...

Excessive online shopping cart abandonment rates constitute a major challenge for e-commerce companies and can inhibit their success within competitive environment. Simultaneously, the emergence of Internet’s commercial usage results in steadily growing volumes data about consumers’ behavior. Thus, data-driven methods are needed to extract valuable knowledge from such big automatically identify abandoners. Hence, this contribution analyzes clickstream leading German retailer comprising...

We report the nanostructures in a novel microemulsion system of silicone oil, water and surfactant mixture an anionic nonionic surfactant. The phase diagram investigated exhibits two isotropic single-phase channels for constant temperature. upper channel, that is channel with higher mass fraction surfactant, starts L3-phase at side, passes through minimum continuously to oil side. lower L1-phase increasing content middle ends there. No connection between was detected concentration 15%. are...

We report a phase diagram for novel microemulsion that consists of oil and water 15% surfactant mixture an anionic nonionic surfactant. The shows optically isotropic channel passes from the water-rich side to oil-rich side. In contrast in microemulsions surfactants, reported system undergoes abrupt transition structure with increasing content. structural is reflected conductivity viscosity channel. Between L(3) sample 6% decreases 3 orders magnitude. Thus, bicontinuous at origin transforms...

Microemulsion phases have been prepared for the first time from silicone oil "M2" (hexamethyldisiloxane) and a surfactant mixture of nonionic "IT 3" (isotridecyltriethyleneglycolether) an ionic Ca(DS)2 (calciumdodecylsulfate). For such hydrophilicity system can be tuned by mixing ratio two components. With increasing IT 3 content, mixtures show L1-phase, wide Lα-region narrow L3 sponge phase. constant temperature, single phase channels exist in microemulsion system. The lower channel (low...

Prosody—the suprasegmental component of speech, including pitch, loudness, and tempo—carries critical aspects meaning. However, the relationship between information conveyed by prosody vs. words themselves remains poorly understood. We use large language models (LLMs) to estimate how much is redundant themselves. Using a spoken corpus English audiobooks, we extract prosodic features aligned individual test well they can be predicted from LLM embeddings, compared non-contextual word...

We have studied the dynamic and rheological properties in single-phase channels of a microemulsion system with mixed anionic/nonionic surfactant decane from aqueous to oil phase. One isotropic channel, called "upper" begins at L(3) phase (sponge-like phase) binary mixture on water side passes shallow minimum for composition side. The other "lower" channel micellar L(1) ends middle diagram. Both are separated by huge anisotropic single L(α) that reaches 90% solvent mixture. structural...

Abstract Customer referral programs (CRPs) are considered an effective means of customer acquisition through which firms stimulate existing customers to refer services and products potential new customers. Digitalization technological developments have led the common practice using digital devices like smartphones or laptops create submit referrals. This is first study investigate influence submission in CRPs from both sender's receiver's perspective. Based on four experiments, we...

ABSTRACT In today's ever‐changing and modern world, user‐generated content (UGC) on the internet exerts a significant influence consumers. Therefore, understanding UGC its design is of great interest to researchers practitioners alike. One examined factor influencing submission device, such as smartphone, tablet, or laptop. Despite digital devices offering similar capabilities for creation submission, they differ substantially in their characteristics, including screen size, user interface,...

The single phase channels of a presently reported microemulsion system were investigated by electrical conductivity and pulsed-field gradient nuclear magnetic resonance (PFG-NMR) spectroscopy. consists mixed anionic–non-ionic surfactant mixture, water decane. At constant concentration temperature, the diagram exhibits two channels, separated an anisotropic lamellar channel. lower channel starts from side with micellar L1 reaches middle increasing mass fraction decane in solvent mixture...

Training on multiple modalities of input can augment the capabilities a language model. Here, we ask whether such training regime improve quality and efficiency these systems as well. We focus text--audio introduce Whisbert, which is inspired by text--image approach FLAVA (Singh et al., 2022). In accordance with Babylm guidelines (Warstadt 2023), pretrain Whisbert dataset comprising only 100 million words plus their corresponding speech from word-aligned version People's Speech (Galvez...
