Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Genetic signatures have added a molecular dimension to prognostics and therapeutic decision-making. However, tumour heterogeneity in prostate cancer and current sampling methods could confound accurate assessment. Based on previously published spatial transcriptomic data from multifocal prostate cancer, we created virtual biopsy models that mimic conventional biopsy placement and core size. We then analysed the gene expression of different prognostic signatures (OncotypeDx®, Decipher®, Prostadiag®) using a step-wise approach with increasing resolution from pseudo-bulk analysis of the whole biopsy, to differentiation by tissue subtype (benign, stroma, tumour), followed by distinct tumour grade and finally clonal resolution. The gene expression profile of virtual tumour biopsies revealed clear differences between grade groups and tumour clones, compared to a benign control, which were not reflected in bulk analyses. This suggests that bulk analyses of whole biopsies or tumour-only areas, as used in clinical practice, may provide an inaccurate assessment of gene profiles. The type of tissue, the grade of the tumour and the clonal composition all influence the gene expression in a biopsy. Clinical decision making based on biopsy genomics should be made with caution while we await more precise targeting and cost-effective spatial analyses.

Why do online grocery shoppers switch? An empirical investigation of drivers of switching in online grocery
- 2020
-
Ingår i: Journal of Retailing and Consumer Services. - : Elsevier. - 0969-6989. ; 53

Tidskriftsartikel (refereegranskat)abstract
- The article sets out to develop a deeper understanding of the drivers of switching behavior in an online grocery context, which is becoming a key area of focus for grocery retailers. Applying the push, pull, and mooring framework (PPM) popularly used in migration and switching literature, we empirically assessed factors that might contribute to online grocery switching. The results highlight that retailer-related push factors (customer service, issues with delivered products, technical issues, and high price perception) and competitor-related pull factors (WOM and alternative attraction) have significant direct effects on switching. Furthermore, the results also show that consumer-related mooring factors (switching cost and prior switching behavior) significantly moderate switching. The findings provide valuable insights to retailers on the drivers of switching behavior in online grocery retailing, which can be used to develop strategies to reduce consumer switching and hence increase consumer retention.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: Given the growing prominence of voice-activated artificial intelligent devices (VAIs) as the strategic market-facing technology for grocery purchases, this article aims to bring together theories on anthropomorphism, trust, emotional attachment, self-connection and self-disclosure in one conceptual framework establishing that consumer–VAI relationship has significant implications for grocery purchase satisfaction and intention to repurchase using VAIs. Design/methodology/approach: The study tested seven hypotheses through a survey-based approach comprising of two studies. Findings: The study empirically supports VAI anthropomorphism and trust in VAIs as predictors of consumer–VAI emotional attachment and establishes the moderating role of consumer self-disclosure. Consumer–VAI self-connection resulting from emotional attachment results in grocery purchase satisfaction and intention to repurchase using VAIs. Research limitations/implications: The article offers a novel perspective on consumer–VAI relationships and the use of VAIs for grocery purchases. It establishes an agentic role of consumers when ordering groceries using VAIs, creating a deeper understanding of how consumer–VAI emotional attachment results in extensions of consumers’ self-identity, resulting in purchase satisfaction and repurchase intention using VAIs. Practical implications: Establishing a consumer–VAI relationship, the article brings out the strategic importance of VAIs for marketers in grocery purchases and repurchases, which can be extended to other purchases. Originality/value: The article offers a new perspective on establishing VAIs as strategically important market-facing devices by examining consumer relationships with VAIs and offering valuable insights on how consumer emotional attachment with VAIs results in satisfaction and intention to repurchase using VAIs. © 2021, Emerald Publishing Limited.

One Vs. Many: who wins? : An empirical investigation of online product display
- 2019
-
Ingår i: International Review of Retail, Distribution and Consumer Research. - : Taylor & Francis (Routledge): SSH Titles. - 1466-4402 .- 0959-3969. ; 29:3, s. 285-305

Tidskriftsartikel (refereegranskat)abstract
- This study questions the unharmonious ways of product displays in online grocery retailing and aims to find if visual complexity of the product display has any impact on behavioral outcomes of online grocery shoppers. Our main finding was that visually complex images, i.e. images with a high number of elements have a negative effect on affective and cognitive states resulting in decreased behavioral intentions. However, when the number of elements in the product display was decreased, i.e. the visual complexity of the product display was reduced, shoppers’ cognitive and affective responses and intentions were similar to when they were exposed to noncomplex images. We also found that arousal and pleasure (parallel mediators) absorption, telepresence, utilitarian and hedonic values and perceived ease of use (serial mediators) mediate the effect that the product display has on behavioral intentions.

There is no place like home : home satisfaction and customer satisfaction in online grocery retailing
- 2022
-
Ingår i: International Review of Retail, Distribution and Consumer Research. - : Informa UK Limited. - 0959-3969 .- 1466-4402. ; 32:4, s. 370-387
-
Tidskriftsartikel (refereegranskat)abstract
- This study acknowledges that home is a central and valenced place for most people, and therefore it is assumed that (a) the content in people’s general category for home issues can be activated easily, particularly by various home-related stimuli, and that (b) the affective charge of such content can have a valence-congruent impact on evaluations of home-related stimuli. These assumptions were the basis for two empirical studies carried out in an online grocery shopping context with respect to home delivery. Both studies indicate that home satisfaction had a positive influence on satisfaction with home delivery–and that home satisfaction had an indirect and positive influence of overall satisfaction with the retailer that provides home delivery. These findings, then, emphasize the need to ‘emplace’ the contemporary online shopper: although the shopper faces an abundance of alternatives only a mouse-click away, he or she is still emplaced in an environment when orders are placed and when goods are received. And when this environment is home, it is particularly likely to influence home-related offers.

Understanding the effects of retailer attributes on customer responses in online grocery retailing
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Online grocery shopping is gaining importance for both customers and retailers. Retailers have recognized the importance of online grocery as an extension of their existing business model, serving as drivers for their marketing and growth strategies. Online grocery retailer attributes such as delivery, pricing, website, products, and customer service influence customers to shop for groceries online. With more customers continuing to gain grocery shopping experience, it is essential to broaden the existing research on grocery retailing, which predominantly focuses on offline (in-store) grocery retailer attributes and creates an understanding of online grocery retailer attributes on customer responses. The existing literature on online grocery has provided valuable insights into who are these online grocery customers, their expectations from retailers, and why they shop for groceries online. However, compared to the extensive body of literature dedicated to offline grocery retailing, studies on understanding the effects of retailer attributes on online grocery customer response are relatively less and are predominantly focused on retailer attributes related to retailer’s website interface. Online grocery customers want convenience from the time they start grocery shopping. For these shoppers, retailer attributes beyond retailer’s website such as delivery, customer service is equally important. The present thesis contributes to research and practice by expanding our current understanding of the effect retailer attributes have on customer responses. More importantly, by examining these attributes one can identify the attributes that are essential to customers to enhance their overall grocery shopping convenience. The empirical results from four articles create a deeper understanding of retailer attributes’ effects on customer responses, furthering our insights beyond the current knowledge of retailer attributes’ effects on customer responses. The articles paint a larger picture, emphasizing the importance of retailer attributes towards enhancing convenience, introducing new technologies such as automated voice-activated devices for grocery purchases, and examining customer responses such as customer experience, customer satisfaction, and behavioral intentions. This thesis can be used as a guide for retailers in implementing strategies that can create positive and favorable customer responses.

Why do online grocery shoppers switch or stay? An exploratoty analysis of consumers´response to online grocery shopping experience
- 2019
-
Ingår i: International Journal of Retail and Distribution Management. - : Emerald. - 0959-0552. ; 47:12, s. 1300-1317

Tidskriftsartikel (refereegranskat)abstract
- Purpose The purpose of this paper is to add to current knowledge of online customer experience (OCE) by examining various drivers and outcomes of online grocery shopping experience that can help researchers and retailers answer the pressing question: "Why do online grocery customers stay or switch?" Design/methodology/approach This study applied netnography and critical incident analysis to a pool of 1,004 reviews captured from forum and review sites dedicated to online grocery shopping. Findings Two broad dimensions of OCE, four attributes and 13 factors corresponding to shoppers' psychological states and their utilitarian and hedonic orientations emerged from the data analysis. The proposed framework, containing these four attributes and corresponding 13 factors, captures the consumers' intention to stay with the current retailer or switch. Research limitations/implications - The study contributes to existing knowledge of OCE by providing a dynamic and yet holistic framework that encompasses experiential states and utilitarian or hedonic orientations in an online grocery context. Although its contributions are valuable to both researchers and practitioners, further quantitative analysis is needed to validate the findings. Practical implications - In addition to providing superior customer experience by implementing the various drivers of OCE identified here, online grocery retailers can use the study findings as a strategic guide toward building a frictionless and pleasurable shopping experience. Originality/value The study employs netnography and critical incident technique to identify experiential attributes such as reliability, responsiveness, return and refund, which are unique OCE attributes in online grocery, a relatively unexamined field of retailing.
