Bridging data and adaptation in agent-based modelling
Agent-based models (ABMs) are powerful tools for simulating complex socioeconomic systems. Reinforcement learning (RL), especially online RL, is increasingly used to model agent behaviour, allowing agents to explore and learn optimal actions from the model environment. However, standard online RL approaches learn from scratch and often fail to incorporate valuable real-world data. Further, while purely offline RL can use this data, it does not ad…
Indigenous Market Participation in Commercial Retail
Commercial markets are institutional environments that shape which products are available and how value is signalled to and perceived by consumers. This study examines how such environments shape Indigenous participation in market exchanges, using Traditional Foods (TFs) in grocery retail as an empirical case. Using loyalty card data from 244 grocery stores in Quebec (2015–2016), we first assessed TF availability and found that only 34.5% of refe…
Quantitative and Spatially Explicit Clustering of Urban Grocery Shoppers in Montreal
This study integrates customer loyalty program data with a synthetic population to analyze grocery shopping behaviours in Montreal. Using clustering algorithms, we classify 295,631 loyalty program members into seven distinct consumer segments based on behavioural and sociodemographic attributes. The findings reveal significant heterogeneity in consumer behaviour, emphasizing the impact of urban geography on shopping decisions. This segmentation a…
Nudging consumers towards the most environmentally friendly warm dish
Switching to food with a lower environmental footprint has a substantial mitigation potential, but consumers still need significant assistance in making the switch. Ecolabels can help guide consumers towards more sustainable food options at the point of sale, without compromising their freedom of choice. However, the efficiency of ecolabels depends on many factors other than the label itself, including the choice settings (school canteen, hospita…

Exploring Pathways of Socioeconomic Inequity in Vegetable Expenditure Among Consumers Participating in a Grocery Loyalty Program in Quebec, Canada, 2015–2017
Vegetable consumption remains consistently low despite supportive policy and investments across the world. Vegetables are available in great variety, ranging in their processing level, availability, cost, and arguably, nutritional value. A retrospective longitudinal study was conducted in Quebec, Canada to explore pathways of socioeconomic inequity in vegetable expenditure. Data was obtained for consumers who participated in a grocery loyalty pro…
Tracing the Single and Combined Contributions of Home-Grown Supply and Health Literacy on Fruit and Vegetable Consumption
Low fruit and vegetable consumption (FVC) remains a global health challenge. Fostering subsistence agriculture through the production and home-grown consumption (HGC) of fruits and vegetables are seen as potential strategies for improving overall FVC, in particular, for developing countries like India. In addition, educational strategies targeting FVC health literacy are also used. Little evidence has documented a connection between these two str…
On the Front Lines in Food Policy
This paper reports a multi-year design-based implementation research (DBIR) that examines practical issues, challenges, and innovations faced by the Montreal food polity in transforming food systems for alleviating insecurity in vulnerable populations. Community organizations in three geographically distinct neighbourhoods were engaged in three distinct city-level collaborative engagement initiatives (coalition of neighbourhood roundtables; place…
Blcfa
In confirmatory factor analysis (CFA), post hoc model modification (PMM) indexes are often used to adjust for possible residual correlations between items. Although the approach is useful for improving model goodness-of-fit, it requires an iterative, one-item-pair-at-a-time procedure that can be tedious and prone to error. This paper provides a didactic discussion in the form of a tutorial of a more efficient and practical alternative and its imp…
Multi-indicator supply chain management framework for food convergent innovation in the dairy business
A comprehensive integrated framework of indicators currently used in lean, agile, sustainable and resilient supply chain paradigms is developed under the umbrella of convergent innovation (CI) and applied to the management of the supply chain of a dairy company, including procurement, processing and distribution of their products to customers. CI is a meta-framework that opens new frontiers for commercial innovation, supply chains and market syst…

Reciprocal Markov Modeling of Feedback Mechanisms Between Emotion and Dietary Choice Using Experience-Sampling Data
With intensively collected longitudinal data, recent advances in the experience-sampling method (ESM) benefit social science empirical research, but also pose important methodological challenges. As traditional statistical models are not generally well equipped to analyze a system of variables that contain feedback loops, this paper proposes the utility of an extended hidden Markov model to model reciprocal the relationship between momentary emot…
An Innovative Approach to Addressing Childhood Obesity
Multi-stakeholder partnerships (MSPs) have become a widespread means for deploying policies in a whole of society strategy to address the complex problem of childhood obesity. However, decision-making in MSPs is fraught with challenges, as decision-makers are faced with complexity, and have to reconcile disparate conceptualizations of knowledge across multiple sectors with diverse sets of indicators and data. These challenges can be addressed by …
Parental attachment insecurity predicts child and adult high-caloric food consumption
Eating habits are established early and are difficult to change once formed. This study investigated the role of caregiver-child attachment quality and its associations with high-caloric food consumption in a sample of middle socio-economic status children and adults, respectively. Survey data were collected from an online questionnaire administered separately to 213 (143 girls) children and 216 parents (adult sample; 180 women). Two studies show…

Waiting Time and Decision Making
Time is a resource. As such, consumers have to make decisions regarding their use of time in the purchase and consumption of goods and services. Using prospect theory and mental accounting as theoretical frameworks, this article investigates whether consumers treat time like money when they make decisions. In a series of studies, we found that the value of consumers' time is not constant but depends on contextual characteristics of the decision s…

Gender Differences in Responses to Emotional Advertising
Two studies examine gender differences in responses to advertising with emotional content that varies on agency—a fundamental component of the male, but not female, stereotype. As hypothesized, males reported a less pleasant viewing experience and a less favorable attitude toward the advertisement (Aad) when a low-agency emotion (i.e., stereotype-incongruent) ad was viewed with another male, while their responses were not affected by the presence…
Intrusions into waiting lines
Four experiments tested whether a waiting line should be viewed as a social system with norms, roles, and obligations for queuers or whether behavior in a queue can be explained solely by individuals' personal interests and cost versus benefit calculations. The 1st 3 studies demonstrated that Ss were more likely to respond to an intruder than to aservice provider who interrupts the service for a specific amount of time even though waiting costs w…
Trend Effects and Gender Differences in Retrospective Judgments of Consumption Emotions
A field study performed at the end of multiday hospital stays investigated trend effects on retrospective global judgments of emotions. Subjects (43 women and 50 men) reported instances of their positive and negative emotions, retrospective global judgments of these emotions, and satisfaction with hospital services. Retrospective global judgments of positive and negative emotions were a positive function of the increase or decrease of the instanc…

Associations among Park Use, Age, Social Participation, and Neighborhood Age Composition in Montreal
Parks provide benefits for the physical, psychological, and social well-being of residents in neighborhood environments. Multilevel logistic regression was used to examine associations between neighborhood- and individual-level characteristics and the lack of park use in Montreal. Data on park use were collected from 787 adults residing in 299 different neighborhoods. Results found that older adults who lived in areas with a younger age compositi…
Associations among socioeconomic status, perceived neighborhood control, perceived individual control, and self‐reported health
Recent research has suggested that perceived control and a person's perceptions of their neighborhood environment may mediate the association between socioeconomic status (SES) and health. This cross‐sectional study assessed whether perceptions of informal social control mediated the association between SES and self‐reported health, and if these two constructs represented distinct mechanisms linking SES with self‐reported health. The sample consi…

Subjective valuation and asymmetrical motivational systems
Studies using the Iowa Gambling Task have revealed individual differences in performance on the task. In this study, we tested the hypothesis that approach and avoidance motivations influence decision making through the process of subjective valuation. We examined the implications of a high sensitivity to gains or losses from two perspectives which we labeled scalar multiplication and valuation by feeling . Using two versions of the Iowa Gambling…

Sense of Mastery and Metabolic Risk
OBJECTIVE: To test the moderating role of the extent of fast-food restaurants in one's immediate environment in the association between mastery and metabolic risk. Higher sense of mastery (perceived control over one's circumstances) has been associated with better metabolic outcomes. Mastery may be instrumental in resisting unhealthful environmental food cues when these become ubiquitous, resulting in a greater health impact of mastery. METHODS: …
