Shelf Management and Space Elasticity

Shelf management is a difficult task in which rules of thumb rather than good theory and hard evidence tend to guide practice. Through a series of field experiments, we measured the effectiveness of two shelf management techniques: “space-to-movement,” where we customized shelf sets based on store-specific movement patterns; and “product reorganization” where we manipulated product placement to facilitate cross-category merchandising or ease of shopping. We found modest gains (4%) in sales and profits from increased customization of shelf sets and 5–6% changes due to shelf reorganization. Using the field experiment data, we modeled the impact of shelf positioning and facing allocations on sales of individual items. We found that location had a large impact on sales, whereas changes in the number of facings allocated to a brand had much less impact as long as a minimum threshold (to avoid out-of-stocks) was maintained

A systematic quantitative determination of the antimicrobial efficacy of grape seed extract against foodborne bacterial pathogens

Concerns regarding the role of antimicrobial resistance (AMR) in disease outbreaks are growing due to the excessive use of antibiotics. Moreover, consumers are demanding food products that are minimally processed and produced in a sustainable way, without the use of chemical preservatives or antibiotics. Grape seed extract (GSE) is isolated from wine industry waste and is an interesting source of natural antimicrobials, especially when aiming to increase sustainable processing. The aim of this study was to obtain a systematic understanding of the microbial inactivation efficacy/potential of GSE against Listeria monocytogenes (Gram-positive), Escherichia coli and Salmonella Typhimurium (Gram-negative) in an in vitro model system. More specifically, for L. monocytogenes, the effects of the initial inoculum concentration, bacterial growth phase and absence of the environmental stress response regulon (SigB) on the GSE microbial inactivation potential were investigated. In general, GSE was found to be highly effective at inactivating L. monocytogenes, with higher inactivation achieved for higher GSE concentrations and lower initial inoculum levels. Generally, stationary phase cells were more resistant/tolerant to GSE as compared to exponential phase cells (for the same inoculum level). Additionally, SigB appears to play an important role in the resistance of L. monocytogenes to GSE. The Gram-negative bacteria under study (E. coli and S. Typhimurium) were less susceptible to GSE as compared to L. monocytogenes. Our findings provide a quantitative and mechanistic understanding of the impact of GSE on the microbial dynamics of foodborne pathogens, assisting in the more systematic design of natural antimicrobial-based strategies for sustainable food safety

Exploring what motivates and sustains support group engagement amongst young people with allergies: a qualitative study

Background Positive self-care behaviours are more likely in young people who engage with allergy support groups, but reasons for this association are not well understood. Objectives This study explored how and why young people engage with allergy support groups to identify what activities and resources are beneficial. Methods In-depth, semi-structured interviews were conducted with young people aged 12-21 years who reported engaging with allergy support groups (in person or on-line). Interviews were audiotaped, transcribed verbatim and analysed using thematic content analysis. Results The 21 participants had a range of allergies; initially most joined support groups on suggestion of their parent/carer although older participants sought groups independently. Feeling included and sharing experiences with people with similar problems/challenges were highly valued. Through membership, young people reported improved self-esteem and confidence in both managing their allergies and lives generally. Information, such as allergy alerts and hard-hitting video campaigns were reported to positively influence adherence to self-care behaviours such as carrying medication which led to sustained engagement. Participants wanted greater availability of allergy support groups, and higher profiles in healthcare and educational settings, as well as through social media. Conclusions and clinical relevance Participants valued the psychological and practical support of networking with others with allergies, and described how membership improved their confidence. This study also provides insight into the ways support groups improve young people’s adherence to medical advice and positive self-care behaviours; participants responded well to hard-hitting video campaigns which appeared to emphasise the severity and susceptibility of anaphylaxis. Participants identified the need for more active promotion of support groups amongst young people and their clinicians, as well as making them available in more localities
