Exploring the Role of Availability and Willingness to Pay Premium in Influencing Smart City Customers' Purchase Intentions for Green Food Products.

This research aims to identify the predictors that influence young, educated customers' intention to purchase green food products in India by utilizing the extended theory of planned behavior which includes elements such as environmental concern, perceived customer effectiveness, willingness to pay a premium, and product availability. A total of 337 customers from a smart city in India participated in this quantitative study and filled out a self-administered questionnaire. PLS-SEM and CFA were used to analyze the obtained data. The findings illustrates that attitude and perceived behavioral control influences purchase intentions, but subjective norms has no effect in the Indian context.

How changes in menu quality associate with subsequent expenditure on (un)healthy foods and beverages in school cafeterias: A three-year longitudinal study.

Evidence of the association between the school food environment and children's and adolescents' diet is mostly cross-sectional, usually based on self-reported behavior, and often conducted in high-income countries. Also, relatively little is known about how variations in menu quality associate with the subsequent expenditure on food and beverages of the same- (vs. cross-) nutritional value. Based on a three-year longitudinal dataset comprised of 4,268,457 purchases made by 20,333 children and adolescents from 54 private schools in Brazil, we unobtrusively assess how changes in (un)healthy product availability associate with students' subsequent purchase behavior. Our results reveal that, on average, only 11.6% of the products offered in the school cafeterias were of high nutritional value (HNV). Critically, expenditure on HNV products increased following both the addition of one HNV product (ß = 0.18; 95% CI = 0.128, 0.240) and, to a lesser extent, the subtraction of one low nutritional value (LNV) product from the menu (ß = -0.03; 95% CI = -0.042, -0.016). Cross-nutritional value effects were stronger for beverages. The inclusion of one HNV beverage was associated not only with a subsequent increase in expenditure on HNV beverages (ß = 0.19; 95% CI = 0.115, 0.264), but also with a decrease in expenditure on LNV beverages (ß = -0.18; 95% CI = -0.352, -0.010).Although only a small percentage of foods and beverages consumed in private school cafeterias in Brazil are of high nutritional value, improvements to menu quality have the potential to increase the consumption of healthier products and decrease the consumption of unhealthy ones.

Comparison of food and beverage products' availability, variety, price and quality in German and US supermarkets.

OBJECTIVE: To assess availability, variety, price and quality of different food products in a convenience sample of supermarkets in Germany and the USA. DESIGN: Cross-sectional study using an adapted version of the Bridging the Gap Food Store Observation Form. SETTING: Information on availability, quality, price and variety of selected food products in eight German and seven US supermarkets (discount and full service) was obtained and compared by country. RESULTS: A general tendency for lower prices of fruits and vegetables in Germany was observed, while produce quality and variety did not seem to differ between countries, with the exception of the variety of some vegetables such as tomatoes. Chips and cereals did not differ significantly in variety nor price. In both countries, high energy-dense foods were lower in energy costs than lower energy-dense foods. CONCLUSIONS: The influence of food prices and availability on consumption should be further explored, including the impact of country differences.

Associations of cannabis product source and subsequent cannabis use among adolescents.

BACKGROUND: Cannabis is obtained from a variety retail and illicit sources, with unknown implications for youth cannabis use. This study assessed whether source of obtaining cannabis was associated with future cannabis use among adolescents. METHODS: High-schoolers (N = 835) completed 3 semiannual surveys, reporting use of 7 cannabis sources (i.e., free, bought from someone, from an online dispensary, with a [valid/invalid] medical card, self-grown, or other; separate dichotomous exposure variables) at wave 1 (n = 621; M[SD] age=17.14[.40]) or wave 2 (n = 622; M[SD] age=17.51[.39]). Past-6-month (yes/no) and number of past-30-day (0-30) non-medical use of any cannabis product, combustible, edible, and vaporized cannabis, blunts, and concentrates (i.e., dabs) were reported at waves 2-3. Random-effect time-lagged repeated-measures regression was used to test longitudinal associations of youth's cannabis source (waves 1-2; time-varying exposure) with cannabis use outcomes 6 months later (waves 2-3). RESULTS: Most youth (72.1%) received cannabis for free; 50.9% bought cannabis from someone, 15.9% used a valid medical card at a brick-and-mortar dispensary, and 3.9% grew cannabis. Buying cannabis from someone (OR=1.46, 95% CI: 1.07-1.99, p = .02) or using a valid medical card (OR=1.99, 95% CI: 1.20-3.31, p = .008) conferred greater odds of any cannabis product use 6 months later. Buying from someone predicted subsequent past-30-day use frequency (RR=1.25, 95% CI:1.05-1.48, p = .01). Some associations between particular cannabis sources and products were observed. CONCLUSIONS: Adolescents may access cannabis from several sources. Those who purchase cannabis illicitly from someone or from a brick-and-mortar dispensary using a valid medical card may be at increased risk for more persistent and frequent patterns of non-medical cannabis use.

Can anticipatory supply chain decision making manage the pandemic's effect? A regime switching game.

The COVID-19 pandemic has shown that stock outs of essential items like hand sanitizers, tissue papers and other items of hygiene and daily use have been characteristic of a supply chain, especially immediately following a pandemic wave. Consequently, retailers have to indulge in substantial supplier management efforts to ensure product availability during a pandemic wave. Using a piecewise deterministic differential game, we model a scenario where, while anticipating a pandemic wave, a supplier decides on product availability efforts to ensure product availability under the impending threat of stock outs. A market leader coordinating retailer, on the other hand, decides on the proportion of the costs of the efforts to be shared with the supplier.

Sources of cannabis among young adults and associations with cannabis-related outcomes.

BACKGROUND: The ways in which young people learn about cannabis product availability and where they obtain cannabis products are important to understand for prevention and intervention efforts. METHODS: Young adults who reported past month cannabis use (N = 758) completed an online survey in 2018-2019 on how they obtained cannabis and the products they used in a newly legalized market in Los Angeles (mean age 21.6; 44% Hispanic, 27% white, 15% Asian). RESULTS: Overall, 59.1% obtained cannabis from recreational cannabis retailers (RCRs), 51.5% from family or friends, 39.1% from medical cannabis dispensaries (MCDs), and 5.5% from strangers or dealers in the past month. Compared to those getting cannabis from family or friends, those getting cannabis from MCDs or RCRs spent more money, used more cannabis products, were more likely to use alone, used greater quantities of bud/flower, and reported more consequences from use. Further, those obtaining cannabis from MCDs were more likely to screen positive for cannabis use disorder (CUD). For type of products, those obtaining cannabis from MCDs or RCRs were more likely to use joints, bongs, pipes, dabs, vape, and consume edibles relative to those obtaining from family or friends. Subgroup differences were found for both source patterns and cannabis-related outcomes. Males and those with a cannabis medical card reported spending more money on cannabis, using more types of products, and indicated more frequent use and greater CUD symptoms and consequences. Compared to Whites, Blacks spent more money on cannabis and used more products, and Hispanics reported using more products and greater quantities of cannabis bud/flower. CONCLUSIONS: Findings highlight the different ways that young adults obtain cannabis, and how young adults with a medical cannabis card may be at greater risk for problems compared to young adults who use cannabis recreationally.

Selecting an appropriate strategy to make quality 7.1 % chlorhexidine digluconate accessible for umbilical cord care.

Achieving increased access to medicines in low- and middle-income countries is a complex issue that requires a holistic approach. Choosing an appropriate manufacturing strategy that can ensure a sustainable supply of these medicines is an essential component of that approach. The Chlorhexidine Working Group, a consortium of more than 25 international organizations, donors, and manufacturers led by PATH, has been working to increase access to 7.1 % chlorhexidine digluconate for umbilical cord care in low- and middle-income countries to reduce neonatal mortality due to infection. The working group initially considered two strategies for manufacture of this commodity: (1) production and global distribution by a multinational company; and (2) production and regional distribution by locally owned companies or subsidiaries of multinational companies based in low- and middle-income countries. Local production may be beneficial to public health and economic development in these countries, yet capability and capacity of pharmaceutical manufacturers, regulatory and legal provisions, and market factors must be carefully assessed and addressed to ensure that local production is the correct strategy and that it contributes to improved access to the medicine. To date, this effort to implement a local production strategy has resulted in successful registration of 7.1 % chlorhexidine digluconate for umbilical cord care by manufacturers in Bangladesh, Kenya, Nepal, and Nigeria. Additionally, the product is now available in domestic and export markets.
