The X-ray afterglow of GRB 081109A: clue to the wind bubble structure

We present the prompt BAT and afterglow XRT data of Swift-discovered GRB081109A up to ~ 5\times 10^5 sec after the trigger, and the early ground-based optical follow-ups. The temporal and spectral indices of the X-ray afterglow emission change remarkably. We interpret this as the GRB jet first traversing the freely expanding supersonic stellar wind of the progenitor with density varying as $\rho \propto r^{-2}$. Then after approximately 300 sec the jet traverses into a region of apparent constant density similar to that expected in the stalled-wind region of a stellar wind bubble or the interstellar medium (ISM). The optical afterglow data are generally consistent with such a scenario. Our best numerical model has a wind density parameter {$A_{*} \sim 0.02$, a density of the stalled wind $n\sim 0.12 {\rm cm}^{-3}$, and a transition radius $\sim 4.5 \times 10^{17}$ cm}. Such a transition radius is smaller than that predicted by numerical simulations of the stellar wind bubbles and may be due to a rapidly evolving wind of the progenitor close to the time of its core-collapse.Comment: 7 pages, 5 figures, 2 tables, MNRAS accepted for publicatio

Reputation: configuring the symmetrical and asymmetrical paths to architecture in a retail setting

Grounded in social identity and attribution theories, this study focuses on the effect of architecture and its components on reputation. The relationships conceptualised were evaluated using data collected from a survey of 489 online and offline UK retail consumers and employees. To accommodate the equifinality and complexity of these relationships, this study employs fuzzy set qualitative comparative analysis, predictive validity and fit validity chec

Making sense of sensory brand experience: constructing an integrative framework for future research

This study asserts that conceptualising sensory brand experience (SBE) as an independent construct is critical to expanding our understanding of experiences provided by brands. To achieve this goal, a rigorous examination of its foundational knowledge structure underpinning the construct is urgently required. Using co-citation analysis examining 151 SBE-related articles with 4,038 citations over more than two decades (1994–2019), six knowledge fields deemed to have constitutive influence on SBE literature have been identified - atmospherics, product evaluation, sensory marketing, service marketing, experiential marketing and brand experience. Combining the results of a hierarchical cluster analysis and a metric multidimensional scaling analysis, the authors located three fundamental premises: (1) brand settings are arbiters of brand meaning; (2) the intrinsic processing of SBE involves the entrainment of exteroceptive and interoceptive processes; and (3) SBE outcomes are non-representational. At the end of the paper, these findings are organised into an integrative framework, highlighting research concerns and research gaps at the antecedent, processing and outcome stages. In doing so, this paper contributes to the conceptual development of SBE by constructing a doctrinal schema for future research undertakings

Experiencing the sense of the brand: the mining, processing and application of brand data through sensory brand experiences

Purpose - This article aims to develop an integrative framework based on a convergence of embodiment, ecological and phenomenological theoretical perspectives, to explain the multiple processes involved in the consumers’ mining, processing and application of brand-related sensory data through a sensory brand experience. Design/methodology/approach – This research adopts a qualitative method by using face-to-face in-depth interviews (retail managers and customers) and focus group interviews (actual customers) with 34 respondents to investigate sensory brand experiences in the context of Chinese shopping malls. Findings - Results show that the brand data mined through multisensory cues (visual, auditory, olfactory, tactile and taste) in a brand setting are processed internally as sensory brand experiences (involving sensory impressions such as fun, interesting, extraordinary, comforting, caring, innovative, pleasant, appealing, convenient), which influence key variables in customer-brand relationships including customer satisfaction, brand attachment, and customer lovemarks. Originality/value – This study has implications for current theory on experiential marketing, branding, consumer-brand relationships, consumer psychology and customer experience management
