Future studies should evaluate individual differences in strategies to create a healthy HFE in the context of a weight loss attempt.

Obesity was more indicative of the HFE than making a weight loss attempt. A weight loss attempt was not associated with food planning behaviors, which may be used for multiple reasons, including organization and time management. Future studies should evaluate individual differences in strategies to create a healthy HFE in the context of a weight loss attempt.

Globally, a tainted drug supply is claiming the lives of tens of thousands of people who use drugs and current measures are not quelling this crisis. Within this context, mothers who have lost a child to substance use have emerged as vocal advocates for drug policy changes. This paper explores mothers' experiences in drug policy advocacy to uncover how they are using their stories to drive policy change.

Critical qualitative and narrative methods informed individual interviews with 43 mothers who had lost a child to substance use from across three regions in Canada British Columbia, Prairie Provinces, and Eastern Provinces. Multisite qualitative analysis (MSQA) provided a rigorous analytical method to identify how social context informed participants' advocacy efforts within and across geographies, together with a theoretical lens from Haraway to understand mothers' activism as situated knowledge.

Mothers' drug policy advocacy was shaped by social context and norms, which influenced the types of advocacal to inform more responsive and impactful drug policy.

To date, efforts to address the drug poisoning epidemic have done little to curb casualties. Mothers whose child's death is related to substance use are one group who are bringing their experiences to advocacy efforts aimed at generating new solutions, including calls for decriminalization and legal regulation of drugs. This and other lived experience perspectives represent a critical voice in decision-making and hold the potential to inform more responsive and impactful drug policy.International commerce and travel have been restricted in order to limit the spread of COVID-19. The illegal trafficking in drugs, which is often concealed in other commercial activity, will be affected by these disruptions. This is particularly true for precursor chemicals, controlled substances of synthetic origin, and new psychoactive substances coming from Asia. China hosts large and under-regulated pharmaceutical and chemical sectors that provide many of the active ingredients used both in legitimate medicines and illicit fentanyl and methamphetamine. Unregulated producers and vendors in China have been supplying drug trafficking organizations in Mexico or using the internet and postal service to directly sell fentanyl to buyers in North America. The magnitude of supply shortages and interrupted trade of chemicals and synthetic drugs coming from China will depend on the breadth and depth of COVID-19's disruptions. In turn, this could impact vulnerable drug-using populations. Drawing on historical account different in a post-COVID world.Understanding the effects of COVID-19 mitigation for persons in group living environments is of critical importance to limiting the spread of the virus. Eganelisib mw In the U.S., residential recovery homes for persons with alcohol and drug disorders are good examples of high-risk environments where virus mitigation procedures are essential. The National Alliance for Recovery Residences (NARR) has taken recommendations developed by the Center for Disease Control (CDC) and applied them to recovery home settings. This paper describes how COVID-19 mitigation efforts in recovery homes may be influenced by two factors. First, while some houses are licensed by states with rigorous health and safety standards, others are not licensed and are subject to less oversight. These homes may be more inconsistent in adhering to mitigation standards. Second, to varying degrees, recovery homes use a social model approach to recovery that contrasts with mitigation procedures such as social distancing and stay-at-home orders. This paper provides examples of ways recovery homes have been forced to adjust to the competing demands of mitigation efforts and social model recovery. The paper also identifies multiple questions that could be addressed by provider-researcher coalitions to inform how social model recovery can navigate forward during the era of COVID-19. As we move forward during the era of COVID-19, providers are encouraged to remember that recovery homes have a history of resilience facing adversity and in fact have their origins in grassroots responses to the challenges of their times.In order to reduce waste collection costs and realize sustainable urban development, this paper investigates a two-echelon collaborative waste collection vehicle routing problem (2E-CWCVRP), considering the cooperation and profit distribution between participants in the collection network. An optimization model for 2E-CWCVRP with the aim to minimize total costs and carbon emissions is constructed. Then, a three-stage solution approach is developed to solve this model, including a k-means clustering for simplifying the problem, and a hybrid heuristic for searching the optimal vehicle routes based on Clarke & Wright algorithm and an adaptive large neighborhood search algorithm (CW-ALNS). Finally, an improved Shapley value model is constructed for determining the costs and carbon emissions reduction amount and the best alliance sequence of each participant. The experiment results indicate that (1) the effectiveness of CW-ALNS algorithm is verified through the benchmark instances; (2) the costs and carbon emissions of the collection network could be reduced simultaneously after the implementation of cooperation; (3) constructing a large collection and transfer network is more efficient than dividing the network into several individual parts. Finally, different alliance sequences are analyzed from the economics and environment perspective and the best alliance sequences are determined.Bio-clogging of geotextile is a big challenge for the leachate collection system in landfills. It is important to understand the characteristics of geotextile bio-clogging to develop control technologies. This study investigated the characteristics of geotextile bio-clogging in municipal solid waste landfill (MSW_G) and bottom ash (BA) co-disposal landfill (BA_G). Results showed that the bio-clogging mass of per area in MSW_G and BA_G was 49 ± 5 g/m2 and 57 ± 3 g/m2, respectively. Bio-clogging was dominated by live cells in both MSW_G and BA_G. The confocal laser scanning microscopy images revealed that live cells percentage was 46% in MSW_G, while it increased to 77% in BA_G. In contrast, the percentage of the dead cells was 47% and 9% in MSW_G and BA_G, respectively. The biofilm formed in BA _G was thinner and denser than that in MSW_G. Based on the microbial analysis, the biofilms of BA_G had a higher genetic amount and diversity than these of MSW_G. The total amount of extracellular polymeric substances in BA_G was 45.
