The impact of brand communication on brand equity through Facebook
Purpose: The purpose of this study is to fill the gap in the discussion of the ways in which firm-created and user-generated social media brand communication impacts consumer-based brand equity metrics through Facebook. Design/methodology/approach: We evaluated 302 data sets that were generated through a standardized online-survey to investigate the impact of firm-created and user-generated social media brand communication on brand awareness/associations, perceived quality, and brand loyalty across 60 brands within three different industries: non-alcoholic beverages, clothing, and mobile network providers. We applied structural equation modeling techniques (SEM) to investigate the effects of social media brand communication on consumersâ perception of brand equity metrics, as well as in an examination of industry-specific differences. Findings: The results of our empirical studies showed that both firm-created and user-generated social media brand communication influence brand awareness/associations; whereas, user-generated social media brand communication had a positive impact on brand loyalty and perceived brand quality. Additionally, there are significant differences between the industries being investigated. Originality/value: This article is pioneering in that it exposes the effects of two different types of social media brand communication (i.e., firm-created and user-generated social media communication) on consumer-based brand equity metrics, a topic of relevance for both marketers and scholars in the era of social media. Additionally, it differentiates the effects of social media brand communication across industries, which indicate that practitioners should implement social media strategies according to industry specifics to lever consumer-based brand equity metrics
A scale to measure consumerâs engagement with social media brand-related content
The purpose of this study is to fill the gap in the literature concerning to the measurement of consumerâs engagement with social media brand-related content (hereafter, CESBC). We introduce empirical evidence for the development and measurement of CESBC scale. The scale is based on the consumer's online brand-related framework and comprises three dimensions: consumption, contribution, and creation. We used qualitative techniques to prepare an initial list of items and tested and validated the CESBC scale with confirmatory factor analysis (CFA). Results (n = 2252) confirmed the three-factor structure of the CESBC and indicated its good psychometric properties
Free analysis and planar algebras
We study 2-cabled analogs of Voiculescu's trace and free Gibbs states on
Jones planar algebras. These states are traces on a tower of graded algebras
associated to a Jones planar algebra. Among our results is that, with a
suitable definition, finiteness of free Fisher information for planar algebra
traces implies that the associated tower of von Neumann algebras consists of
factors, and that the standard invariant of the associated inclusion is exactly
the original planar algebra. We also give conditions that imply that the
associated von Neumann algebras are non- non- rigid factors
Determination of the X-ray reflection emissivity profile of 1H 0707-495
When considering the X-ray spectrum resulting from the reflection off the
surface of accretion discs of AGN, it is necessary to account for the variation
in reflected flux over the disc, i.e. the emissivity profile. This will depend
on factors including the location and geometry of the X-ray source and the disc
characteristics. We directly obtain the emissivity profile of the disc from the
observed spectrum by considering the reflection component as the sum of
contributions from successive radii in the disc and fitting to find the
relative weightings of these components in a relativistically-broadened
emission line. This method has successfully recovered known emissivity profiles
from synthetic spectra and is applied to XMM-Newton spectra of the Narrow Line
Seyfert 1 galaxy 1H 0707-495. The data imply a twice-broken power law form of
the emissivity law with a steep profile in the inner regions of the disc (index
7.8) and then a flat region between 5.6rg and 34.8rg before tending to a
constant index of 3.3 over the outer regions of the disc. The form of the
observed emissivity profile is consistent with theoretical predictions, thus
reinforcing the reflection interpretation.Comment: 9 pages, 10 figures. Accepted for publication in MNRA
User-generated images and its impact on consumer-based brand equity and on purchase intention
Researchers and brand managers have limited knowledge of the effects that different types of user-generated content (UGC) have on consumersâ perception of brands and behavior. In this study we investigated 301 authors of a specific category of UGC, i.e., user-generated images (UGI) on a social networking site to confirm the relationships of four drivers reported in literature (co-creation, empowerment, community, and self-concept) to the consumers involvement with UGI, and consequently how it impacts consumer-based brand equity and purchase intention. When analyzing the data, we applied the structural equation modeling technique with Mplus software. The results of the empirical study showed that from the four drivers, only the perception of community influenced the consumersâ involvement with the creation of brand-related images. Subsequently, the consumersâ involvement with UGI directly affected both brand equity and brand purchase intention
Deep Learning and Statistical Models for Time-Critical Pedestrian Behaviour Prediction
The time it takes for a classifier to make an accurate prediction can be
crucial in many behaviour recognition problems. For example, an autonomous
vehicle should detect hazardous pedestrian behaviour early enough for it to
take appropriate measures. In this context, we compare the switching linear
dynamical system (SLDS) and a three-layered bi-directional long short-term
memory (LSTM) neural network, which are applied to infer pedestrian behaviour
from motion tracks. We show that, though the neural network model achieves an
accuracy of 80%, it requires long sequences to achieve this (100 samples or
more). The SLDS, has a lower accuracy of 74%, but it achieves this result with
short sequences (10 samples). To our knowledge, such a comparison on sequence
length has not been considered in the literature before. The results provide a
key intuition of the suitability of the models in time-critical problems
