The demand for food delivery services (FDSs) during the COVID-19 crisis has been fuelled by consumers who prefer to order meals online and have it delivered their door than wait at a restaurant. Since many restaurants moved joined FDSs such as Uber Eats, Menulog, Deliveroo, customer reviews on internet platforms become valuable source of information about company's performance. FDS organisations strive collect complaints effectively utilise identify improvements needed enhance satisfaction. However, only few opinions are addressed because large amount feedback data lack service consultants. Organisations can use artificial intelligence (AI) instead relying experts find solutions own save money opposed reading each review. Based literature, deep learning (DL) methods shown remarkable results in obtaining better accuracy when working with datasets other domains, but explainability model. Rapid research explainable AI (XAI) explain predictions made opaque models looks promising remains be explored domain.

Background: This study aims to examine how behavioral variables interact with and stimulate purchasing decisions influence the process of healthy foods during COVID-19 pandemic. Method: Principal component analysis was carried out on a sample 100 consumers in Saudi Arabia, this made it possible adapt items context study. Exploratory confirmatory 360 people out. Confirmatory factor provided reliable valid scales, multivariate using structural equations binary logistic regressions validate hypotheses. Results: The intention buy increased among foods. Women were more anxious about pandemic than men, they took considerable precautions avoid contamination. fear also intense elderly population younger people. respondents indicated reduced visits shops, restaurants, markets. Gender age moderated relationship between intention. Consumption risk negatively affected However, buying experiences led purchases compared other goods.

Abstract This study explores how firms sought to effectively match their internal competence with external resources from the supply chain network improve operational resilience (OR) during COVID‐19 pandemic. Drawing upon matching theory, this provides an internal–external perspective based on flexibility–stability features of OR explain mechanisms underlying different matchings between flexibility (i.e., product diversity)/stability efficiency) and structural holes)/stability centrality). We find that more heterogeneous (external) (internal) stability have a complementary effect enhances OR, whereas homogeneous (or stability) substitutive reduces OR. valuable contributions research focusing chain, organizational resilience, operations management.

This cross-sectional study was conducted via an online survey obtain overview food access, intake, physical activity residents during initial stage lockdown, investigate association between staying at home/working from home changes lifestyles. A total 2702 participants (70.7% women) were included. Most maintained their habitual diet, while 38.2% increased snack 54.3% reported reduced activity, 45.5% had sleep duration. people (70.1%) no change body weight, 25.0% increase. Always associated with increase animal product, vegetable, fruit, mushroom, nut, water, as well duration frequency skipping breakfast (odds ratio (OR) 1.54, 1.62, 1.58, 1.53, 1.57, 1.52, 1.77, 2.29, 1.76 respectively). Suggestions should be made encourage reduce maintain daily consumption breakfast, future periods.

This study aimed evaluate changes in dietary habits and lifestyle during lockdown specific with academic professional knowledge food sciences from Spain. An online questionnaire, based on 41 items, including sociodemographic data, habits, food-related behaviors, were distributed using institutional mailing lists social media. Results showed higher intake fruit vegetables, legumes, eggs, fish, yogurt together decrease consumption alcoholic beverages between before period. Nevertheless, an increase some fruitive foods self-reported weight also observed, although lower percentages than other populations. A worse sleep quality working hours sitting time reported. Overall, trends towards healthier observed within sample confinement

Aims: This study aimed to describe how the first phase of coronavirus disease 2019 (COVID-19) pandemic affected older persons from general Finnish population who are at risk developing or have cognitive impairment, specifically, whether participants experienced a change in factors that relevant for prevention decline including diet, physical activity, access medical care, socially and cognitively stimulating activities, emotional health well-being. Method: A postal survey was sent June 2020 859 Geriatric Intervention Study Prevent Cognitive Impairment Disability (FINGER), an ongoing longitudinal study. The developed assess effect COVID-19 related infection-control measures on daily life, specifically commitment distancing measures, care social services, changes activities. Results: By September 2020, 613 (71%) responded (mean age = 77.7 years, 32% lived alone, 80% had least one chronic condition). Three quarters adopted some practices during months pandemic. Older were more likely practice total isolation than younger ones (29 vs. 19%; p 0.003). Non-acute health-care visits canceled 5% needed appointments, but cancellations dental (43%), home aid (30%), rehabilitative services (53%) common. Pandemic-related reported engagements, example, less contact with friends (55%) family (31%), frequent attendance cultural events (38%) associations (25%), although remote others increased 40%. Feelings loneliness 21%, particularly those ( 0.023) living alone &lt; 0.001). Physical activity reduced 34%, dietary habits remained stable improved. lifestyle activities evident among alone. Conclusions: generally negative lifestyles behaviors expected. people seemed susceptible changes. It is important compare coping strategies may other European countries identify help individuals maintain healthy future waves COVID-19.
