“…Nonetheless, we can extract meaningful benchmarks from this large dataset which estimates an increase in median RT of 50% for LMRI studies with a CSS of ~ 12 relative to a normal study (CSS = 0). The Current Procedural Terminology (CPT) Code for non-contrast LRMI (72,148) in the Washington, DC area, is assigned a global RVU of 6.32, of which 1.48 RVU is allocated for physician work (estimated payment ranging from $220.87 to $273.47) [ 4 , 18 , 19 ]. LMRI can therefore account for a considerable portion of revenue for both academic and private groups.…”

The Composite Severity Score for Lumbar Spine MRI: a Metric of Cumulative Degenerative Disease Predicts Time Spent on Interpretation and Reporting

Conventional measures of radiologist efficiency, such as the relative value unit, fail to account for variations in the complexity and difficulty of a given study. For lumbar spine MRI (LMRI), an ideal performance metric should account for the global severity of lumbar degenerative disease (LSDD) which may influence reporting time (RT), thereby affecting clinical productivity. This study aims to derive a global LSDD metric and estimate its effect on RT. A 10-year archive of LMRI reports comprising 13,388 exams was reviewed. Objective reporting timestamps were used to calculate RT. A natural language processing (NLP) tool was used to extract radiologist-assigned stenosis severity using a 6-point scale (0 = “normal” to 5 = “severe”) at each lumbar level. The composite severity score (CSS) was calculated as the sum of each of 18 stenosis grades. The predictive values of CSS, sex, age, radiologist identity, and referring service on RT were examined with multiple regression models. The NLP tool accurately classified LSDD in 94.8% of cases in a validation set. The CSS increased with patient age and differed between men and women. In a univariable model, CSS was a significant predictor of mean RT (R2 = 0.38, p < 0.001) and independent predictor of mean RT (p < 0.001) controlling for patient sex, patient age, service location, and interpreting radiologist. The predictive strength of CSS was stronger for the low CSS range (CSS = 0–25, R2 = 0.83, p < 0.001) compared to higher CSS values (CSS > 25, R2 = 0.15, p = 0.05). Individual radiologist study volume was negatively correlated with mean RT (Pearson’s R = − 0.35, p < 0.001). The composite severity score predicts radiologist reporting efficiency in LMRI, providing a quantitative measure of case complexity which may be useful for workflow planning and performance evaluation.

“…As some brands position their products on features aligned with the lifestyle of their consumers (Chernev, Hamilton, & Gal, 2011), using brands as a means to favour belonging is related to preceding research where some have argued that individuals use the symbolic nature of consumption to communicate information about themselves to others (Hammerl et al, 2016;Mead et al, 2011;Ratner et al, 1999). In particular, branded products and consumer practices are used to project an individual's identity to others within their social environment (Berger & Heath, 2007;Belk, 1988;Holt, 1997).…”

“…They call it social value, meaning the perceived utility of the product's association with specific groups. Brands or products can serve as guides for signalling approval, and thus can perform as instruments to assist relationships with others, and to enable affiliation (Berger & Heath, 2007;Hammerl et al, 2016;Ratner, Kahn, & Kahneman, 1999). Baumeister and Leary also described different dimensions with which this need may be related.…”

“…The suggestion that consumption is often a person-thing-person relationship, or clientbrand as proposed by Muniz & O'Guinn (2001), is witnessed in the so-called brand communities, where a specific brand functions as the axis that gives rise to interpersonal closeness and grounds the sense of belonging between individuals in that community (Algesheimer et al, 2005;McAlexander, Schouten, & Koenig, 2002;Muniz & O'Guinn, 2001). Brand communities are a set of social relationships that are structured around the use of a particular brand (Ahuvia, 2005;Berger & Heath, 2007;Bettman & Escalas, 2005;Goulding et al, 2013;Muniz & O'Guinn, 2001), between members who share a system of values, standards and representations (Cătălin & Andreea, 2014), and who have an identity based on that brand (McAlexander et al, 1981), or around shared ownership of a product (Ahuvia, 2005;Ruiz, 2005). Some authors refer to brand tribes rather than communities, although there does not seem to be any consensus on the differences between the two terms, and they are used interchangeably (Cova & Pace, 2006).…”

Shopping to belong: Testing and advancement of a framework on consumer behaviour aimed to promote belonging

Much research has been conducted on how consumption is related to human relations, for example, consumer communities organized around specific brands or the way people use products to define their own identity and transmit a desired image. However, only a scarcity of research has examined the consumption process when the fundamental intention is to leverage group belonging. The literature comprises a single theoretical framework that describes this behaviour, a nascent proposition that has not been tested. This study reviews the transferability of the model and its descriptive extent of the phenomenon in a different context than the one originally used for its proposal. A qualitative deductive case study and a pattern matching analysis technique were employed. The findings revealed that the model is transferable, thus revealing its suitability for future research on consumer behaviour intentionally aimed to promote belonging. The study also expands the framework with precisions on its conceptualization.

“…Такая ситуация в целом может характеризовать и современные паттерны потребления (Rössel & Pape 2016). С другой стороны, все чаще наблюдается и ситуация, когда потребление опосредовано менее масштабными и менее устойчивыми типизациями (Berger & Heath 2007;Kleine, Kleine, & Kernan 1993), в том числе и стилями жизни (Rössel & Pape 2016).…”

Metasemiotic Projects and Lifestyle Media: Formulating Commodities as Resources for Identity Enactment

There has recently been a notable increase in the amount and perceived significance of new lifestyle media. Besides the instructive and entertaining function, these media arguably play a more fundamental sociocultural role of constructing identities. In consumer societies, these identities are to a great extent enacted through the acquisition of commodities and engagement in commodified practices, which thereby become semiotic resources of identity stylization. The purpose of this article is to explore the discursive mechanisms underpinning the process of formulating commodities and practices as such semiotic resources. To this end, several discourses from new online men’s magazines have been analyzed drawing on a model of discourse analysis that sees discourse as one of the “moments” of the social practice it is embedded in. The results indicate that the mechanism behind the processes in question can be described as a metasemiotic project. As such a project unfolds in discourse, various commodities and practices are being typified by a metasemiotic term. One of the most frequent prototypical metasemiotic terms in these resources is stylish man . The term is instantiated in texts by several lexemes, including the lexeme style and its derivatives, as well as lexemes naming various “masculine personas” such as man , guy, kid, gentleman, bad ass. It has been shown that an increasing number of commodities and practices are being “theorized” by the discourse of new online men’s magazines and typified by this term. One important feature behind the workings of the metasemiotic project is intertextuality. Specific texts are always dialogically linked to other texts of lifestyle discourse, while object-signs are reformulated and imbued with different social values. These results contribute to the exploration of contemporary lifestyle media and discursive mechanisms of identity construction used by them, and, in a more general sense, to recent discussions of operationalizing wider sociocultural context in textually oriented discourse analysis.
