  • Greenwashing : Teaching from Marketing & Sustainability
  • 2023
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • This session is based on the book “Marketing & Sustainability: Why and how sustainability is changing current marketing practices” (Guyader et al. 2020, Studentlitteratur). The authors host a workshop about using the concept of greenwashing in the classroom, and they open for discussion with fellow teachers about teaching marketing with a sustainability approach. The session begins with a short introductory presentation of the book content, with a focus on the practice of greenwashing — before moving-on to a workshop/discussion of greenwashing cases in Sweden.

  • Identifying the resource integration processes of green service
  • 2019
  • Ingår i: Journal of Service Management. - : Emerald Group Publishing Limited. - 1757-5818 .- 1757-5826. ; 31:4
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: The purpose of this paper is to improve the understanding of green service. In particular, the focus is on identifying homopathic and heteropathic resource integration processes that preserve or increase the resourceness of the natural ecosystem. Design/methodology/approach: Through an extensive multiple case study involving ten service providers from diverse sectors based on a substantial number of interviews, detailed accounts of green service are provided. Findings: Six resource integration processes were identified: reducing, recirculating, recycling, redistributing, reframing and renewing. While four of these processes are based on homopathic resource integration, both reframing and renewing are based on heteropathic resource integration. While homopathic processes historically constitute a green service by mitigating the impact of consumption on the environment, heteropathic resource integration increases the resourceness of the natural ecosystem through emergent processes and the (re)creation of natural resources. Research limitations/implications: The present study breaks away from the paradigm that “green service” is about reducing the negative environmental impact of existing services, toward providing a green service that expands biological diversity and other natural resources. Originality/value: Transformative service research on environmental sustainability is still in its infancy. The present study contributes through conceptualizing green service, redefining existing resource integration processes (reducing, recirculating, recycling) and identifying new resource integration processes (redistributing, reframing, renewing).

  • Marketing and sustainability : why and how sustainability is changing current marketing practices
  • 2020. - 1
  • Bok (övrigt vetenskapligt/konstnärligt)abstract
    • This book aims to equip business students and marketing practitioners with a thorough understanding of sustainability issues. It uses contemporary cases and useful conceptualizations from recent research to provide a toolbox that help the reader understand how to deliver value to today’s consumers, while considering the well-being of future generations.Marketing & Sustainability raises important questions concerning the impact of (over)consumption, production, distribution, and communication, all key marketing activities, on socio-environmental challenges in the world — such as climate change and natural resource depletion.Servitization, dematerialization of consumption, the emergence of the circular economy paradigm, the platform-based sharing economy paradigm and the use of sharing schemes and platform-based exchanges of existing market goods are all dealt with in this book, which will make a lot of sense for students, marketers and other professionals who are aware of and striving for sustainable growth.

  • Sustainability & Marketing
  • 2019
  • Konferensbidrag (populärvet., debatt m.m.)abstract
    • This session is based on the upcoming book “Marketing & Sustainability” (Studentlitteratur 2020) which aims to equip business students with the relevant mindset to pursue advanced marketing education or start their career as marketer with an understanding of sustainability issues — with contemporary cases and useful conceptualisations and classifications.The presentation will cover (1) classic consumer behavior concepts (e.g., consumer segmentations, the consumption process) and how to influence consumer behavior in light of infamous attitude-behavior “green gap” (e.g., nudging); (2) firms’ operations and responses to the sustainability imperative (e.g., new product/service development, the life-cycle approach, ISO standards, open innovation); (3) sustainable marketing communications (e.g., branding, certifications and labelling, communication channels) and the pitfalls of “cheating the consumers” (e.g., greenwashing issues, transparency, GDPR implications); and (4) the diverse sustainable business models and marketing channels (e.g., Product-Service Systems, circular economy paradigm, peer-to-peer platforms).

  • The Heart and Wallet Paradox of Collaborative Consumption
  • 2019
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Collaborative consumption is a peer-to-peer (P2P) exchange of goods and services facilitated by online platforms. This phenomenon is driven by technologies that make it easier and cheaper to redistribute and share the use of existing but underutilized private resources. It is embedded in the paradigm shift in society towards access-based consumption, in opposition to acquisition and private individual ownership. Firms take on the new role of enabler of collaborative consumption by developing online platforms and smartphone apps that facilitate P2P exchanges between people in their roles of peer providers and consumers.Collaborative consumption is anchored to two opposite logics of consumption: sharing and market exchange. This results in the Heart & Wallet paradox with its tensions between a pro-social orientation and communal norms on the one hand, and a for-profit orientation and market norms on the other hand. While diverse societal and regulatory aspects of the so-called “sharing economy” are discussed in popular debate, scholars have yet to catch up on the theoretical implications from these influences on business activities and consumer behavior.This thesis aims to improve the understanding of collaborative consumption by contributing to the conceptualization of this new phenomenon as intertwined with coexisting sharing and market logics. The research is based on two papers taking the perspective of the firms operating online platforms that facilitate collaborative consumption, and two papers taking the perspective of the peer providers and consumers participating in P2P exchanges. The context of shared mobility (i.e. P2P car rental, ridesharing) is explored through three cases, using interviews with online platform managers and participants in collaborative consumption, participant observation, a netnography, a cross-sectional survey of platform users, and document analyses.This thesis situates collaborative consumption in the access paradigm, based on the temporal redistribution and monetization of private resources facilitated via online platforms, while nurturing the feelings of communal belonging and the sharing ethos embedded in P2P exchanges. Investigating the tensions of the Heart & Wallet paradox of collaborative consumption, I highlight the opposing rationales between the sharing logic of the original nonmonetary practices initiated by grassroots communities and the market logic of platform business models. I further emphasize the key function of communal identification for participants and the role of perceived sharing authenticity—the pitfalls of sharewashing for firms. This thesis contributes to service research by advancing the understanding of P2P exchanges and the conceptualization of collaborative consumption.

  • You can't buy what you can't see: Retailer practices to increase the green premium
  • 2017
  • Ingår i: Journal of Retailing and Consumer Services. - : Elsevier. - 0969-6989 .- 1873-1384. ; 34, s. 319-325
  • Tidskriftsartikel (refereegranskat)abstract
    • Retailers are the gatekeepers between consumers and eco-friendly products. As such, they can influence green shopping behavior. The results of an eye-tracking experiment show that retailers can attract consumers’ visual attention and increase the green premium through various practices such as providing relevant information, orienting consumers inside the store, and offering an eco-friendly product assortment. Managerial implications are to use green-colored price tags to signal eco-friendly products, while avoiding greenwashing practices that can distract consumers from finding the eco-friendly products they look for.

  • BEST: Bypass equipoise sleeve trial; rationale and design of a randomized, registry-based, multicenter trial comparing Roux-en-Y gastric bypass with sleeve gastrectomy
  • 2019
  • Ingår i: Contemporary Clinical Trials. - : Elsevier BV. - 1551-7144 .- 1559-2030. ; 84
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Laparoscopic gastric bypass (LGBP) is a well-documented surgical intervention for severe obesity. Recently, laparoscopic sleeve gastrectomy (LSG) has gained increased popularity. Short-term follow-up in limited-sized randomized trials comparing LGBP and LSG show no major differences in weight-loss, adverse events, or effect on comorbidities; however, there is a lack of sufficiently powered, pragmatic, randomized controlled trials comparing the mid- and long-term results of the two methods. Method: BEST is a randomized, registry-based, multicenter trial comparing LGBP and LSG. The trial has two primary outcomes; rates of substantial complications (SC) and total body weight loss. We hypothesize that patients treated with LSG will experience 35% fewer substantial complications during the 5-year follow-up compared to patients treated with LGBP, and that the efficacy of LSG will remain within a non-inferiority margin of 5% in terms of weight loss. Our sample size calculation, using data from the Scandinavian Obesity Surgery Registry (SOReg), shows a power of 80% for SC and > 95% for weight loss at p < .025 with a total of 2100 included patients. The design of the trial will also enable comparisons within several relevant patient subgroups. Conclusions: As a large-sized, pragmatic, randomized trial, BEST will provide robust data comparing LGBP with LSG by generating long-term results on weight loss and SC's, as well as secondary outcomes and comparisons within patient subgroups. The use of a well-established registry for registration of all data facilitates a large multicenter trial, and combines the strengths of registry studies with those of a randomized trial.

  • Comparison of Sleeve Gastrectomy vs Roux-en-Y Gastric Bypass : A Randomized Clinical Trial
  • 2024
  • Ingår i: JAMA Network Open. - : American Medical Association (AMA). - 2574-3805. ; 7:1
  • Tidskriftsartikel (refereegranskat)abstract
    • IMPORTANCE: Laparoscopic sleeve gastrectomy (SG) and laparoscopic Roux-en-Y gastric bypass (RYGB) are widely used bariatric procedures for which comparative efficacy and safety remain unclear.OBJECTIVE: To compare perioperative outcomes in SG and RYGB.DESIGN, SETTING, AND PARTICIPANTS: In this registry-based, multicenter randomized clinical trial (Bypass Equipoise Sleeve Trial), baseline and perioperative data for patients undergoing bariatric surgery from October 6, 2015, to March 31, 2022, were analyzed. Patients were from university, regional, county, and private hospitals in Sweden (n = 20) and Norway (n = 3). Adults (aged ≥18 years) eligible for bariatric surgery with body mass indexes (BMIs; calculated as weight in kilograms divided by height in meters squared) of 35 to 50 were studied.INTERVENTIONS: Laparoscopic SG or RYGB.MAIN OUTCOMES AND MEASURES: Perioperative complications were analyzed as all adverse events and serious adverse events (Clavien-Dindo grade >IIIb). Ninety-day mortality was also assessed.RESULTS: A total of 1735 of 14 182 eligible patients (12%; 1282 [73.9%] female; mean (SD) age, 42.9 [11.1] years; mean [SD] BMI, 40.8 [3.7]) were included in the study. Patients were randomized and underwent SG (n = 878) or RYGB (n = 857). The mean (SD) operating time was shorter in those undergoing SG vs RYGB (47 [18] vs 68 [25] minutes; P < .001). The median (IQR) postoperative hospital stay was 1 (1-1) day in both groups. The 30-day readmission rate was 3.1% after SG and 4.0% after RYGB (P = .33). There was no 90-day mortality. The 30-day incidence of any adverse event was 40 (4.6%) and 54 (6.3%) in the SG and RYGB groups, respectively (odds ratio, 0.71; 95% CI, 0.47-1.08; P = .11). Corresponding figures for serious adverse events were 15 (1.7%) for the SG group and 23 (2.7%) for the RYGB group (odds ratio, 0.63; 95% CI, 0.33-1.22; P = .19).CONCLUSIONS AND RELEVANCE: This randomized clinical trial of 1735 patients undergoing primary bariatric surgery found that both SG and RYGB were performed with a low perioperative risk without clinically significant differences between groups.TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02767505.

  • Corrosion of copper in pure O2-free water?
  • 2018
  • Ingår i: Corrosion Science. - : Elsevier BV. - 0010-938X .- 1879-0496. ; 137, s. 1-12
  • Tidskriftsartikel (refereegranskat)abstract
    • Copper exposed to pure, O-2-free water for several months in glass- and metal-contained, well-controlled systems shows no evidence of corrosion, either through hydrogen evolution or through the occurrence of oxidized copper. The results contradict the interpretation of recent experiments where it has been claimed that copper corrodes in pure, O-2-free water far above the very limited extent predicted by established thermodynamic data. Reasons for the different experimental outcomes are discussed. Experimental and theoretical efforts to identify hitherto unknown, potentially corrosion driving species of the Cu-O-H system and studies of copper/water surface reactions are reviewed as background for the present study.
