Background: In response to the specific goals of carbon peaking and neutrality, remanufacture is becoming increasingly popular. With the marketplace being more and more adopted, an independent remanufacturer (IR) could sell its products via either the reselling model or the marketplace model. In order to contribute more to carbon neutrality, we investigate the optimal marketing decision for remanufacturing. We construct two models namely reselling model and the marketplace model, and further explore the effects of each marketing model on the decisions and profits of both the IR and the platform firm. Methods: We examine a platform firm that sells new products and an IR that sells remanufactured products under two marketing models based on game theory: (1) a reselling model in which the IR sells remanufactured products to the platform firm; then the platform firm resells to consumers; (2) a marketplace model in which the IR sells remanufactured products to consumers through the platform. Results: Our results show that aiming at carbon neutrality, the IR would be induced by the marketplace model to undertake remanufacturing operations and remanufacture products as many as it could still meet the market demand. Meanwhile, the marketplace model encourages the IR to rethink its work and manufacture more products under certain conditions. Furthermore, both the platform firm and the IR prefer the marketplace model to the reselling model within a Pareto zone. In addition, we find that both the platform firm and the IR could benefit from the marketplace model when they take carbon neutrality under consideration. Conclusions: This study provides managerial insight from two aspects. Remanufactures could decide their marketing model via thorough consideration of market competition, commission rate, and production cost. The government could do more to protect the marketplace environment in order to stimulate the internal vitality of the platform in the achievement march of carbon neutrality purpose. That is, this study will provide good guidance for sustainable development decision-making of remanufacturing marketing platforms, and further contributes to the achievement of the carbon neutrality goal.

INTRODUCTION: The aim of this study was to document the scope of violations of the Canadian Radio-television and Telecommunications Commission (CRTC) "Code for Broadcast Advertising of Alcoholic Beverages" (CRTC Code) by drinking venues posting alcohol-related content on social media platforms, and to assess whether CRTC Code violations by drinking venues relate to their popularity among university students and to students' drinking behaviours. METHODS: In phase 1 of the study, a probability sample of 477 students from four Canadian universities responded to a questionnaire about their drinking and preferred drinking venues. In phase 2, a probability sample of 78 students assessed the compliance of drinking venues' social media posts with the 17 CRTC Code guidelines. We pooled both datasets and linked them by drinking venues. RESULTS: Popular drinking venues were overwhelmingly posting alcohol-related content that contravenes the CRTC Code. Adjusted effect estimates show that a decrease in the mean level of compliance with the CRTC Code was significantly associated with a 1% increase in popularity score of drinking venues (t-test, p < .001). With regard to drinking behaviours, a 1% increase in the overall mean level of compliance with the CRTC Code was associated with 0.458 fewer drinking days per week during a semester (t-test, p = .01), 0.294 fewer drinks per occasion (t-test, p = .048) and a lesser likelihood of consuming alcohol when attending a drinking venue (t-test, p = .001). CONCLUSION: The results of this study serve as a reminder to territorial and provincial regulatory agencies to review their practices to ensure that alcohol advertising guidelines are applied and enforced consistently. More importantly, these results call for the adoption of federal legislation with a public health mandate that would apply to all media, including print, television and radio, digital and social.

Abstract

Introduction
Managed Alcohol Programs (MAPs) are designed to improve health and housing outcomes for unstably housed people with an alcohol use disorder (AUD). The present study assesses the association of MAP participation with healthcare and mortality outcomes.


Methods
A retrospective cohort study assessed health outcomes for 205 MAP participants and 128 controls recruited from five Canadian cities in 2006–2017. Survival and negative binomial regression models were used to calculate hazard ratios (HR) of death and emergency room (ER) visits and hospital bed days (HBDs). Covariates included age, sex, AUD severity and housing stability score.


Results
In fully adjusted models, compared with times outside MAPs, participants had significantly reduced risk of mortality (HR = 0.37, P = 0.0001) and ER attendance (HR = 0.74, P = 0.0002), and fewer HBDs yearly (10.40 vs 20.08, P = 0.0184). Over the 12 years, people enrolled in a MAP at some point had significantly fewer HBDs per year than controls after MAP enrolment (12.78 vs 20.08, P = 0.0001) but not significantly different rates of death or ER presentation. MAP participants had significantly more alcohol-related but significantly fewer nonalcohol-related ER presentations than controls.


Conclusion
Attendance at a MAP was associated with reduced risk of mortality or morbidity and less hospital utilization for individuals with unstable housing and severe AUDs. MAPs are a promising approach to reduce mortality risk and time spent in hospital for people with an AUD and experiencing homelessness.
