Objective To evaluate the effects of lowering prices and increasing availability on sales of healthy foods and beverages from 33 vending machines in four bus garages as part of a multi-component worksite obesity prevention intervention. Methods Availability of healthy items was increased to 50% and prices were lowered at least 10% in the vending machines in two metropolitan bus garages for an 18-month period. Two control garages offered vending choices at usual availability and prices. Sales data were collected monthly from each of the vending machines at the four garages. Results Increases in availability to 50% and price reductions of an average of 31% resulted in 10-42% higher sales of the healthy items. Employees were most price-responsive for snack purchases. Conclusions Greater availability and lower prices on targeted food and beverage items from vending machines was associated with greater purchases of these items over an eighteen-month period. Efforts to promote healthful food purchases in worksite settings should incorporate these two strategies. PMID:20061884

Residents of some low-income neighborhoods have limited access to fresh fruits and vegetables. In 2008, New York City issued new mobile fruit and vegetable cart licenses for neighborhoods with inadequate availability of fresh produce. Some of these carts were equipped with electronic benefit transfer (EBT) machines, allowing them to accept Supplemental Nutrition Assistance Program (SNAP) benefits. This article examines the association between type and quantities of fruits and vegetables purchased from mobile fruit and vegetable vendors and consumer characteristics, including payment method. Customers at 4 produce carts in the Bronx, New York, were surveyed during 3 periods in 2013 and 2014. Survey data, including purchased fruit and vegetable quantities, were analyzed using multivariable negative binomial regressions, with payment method (cash only vs EBT or EBT and cash) as the primary independent variable. Covariates included availability of EBT, vendor, and customer sociodemographic characteristics. A total of 779 adults participated in this study. Shoppers who used SNAP benefits purchased an average of 5.4 more cup equivalents of fruits and vegetables than did shoppers who paid with cash. Approximately 80% of this difference was due to higher quantities of purchased fruits. Expanding access to EBT machines at mobile produce carts may increase purchases of fruits and vegetables from these vendors.

This study examined the effects of pricing and promotion strategies on purchases of low-fat snacks from vending machines. Low-fat snacks were added to 55 vending machines in a convenience sample of 12 secondary schools and 12 worksites. Four pricing levels (equal price, 10% reduction, 25% reduction, 50% reduction) and 3 promotional conditions (none, low-fat label, low-fat label plus promotional sign) were crossed in a Latin square design. Sales of low-fat vending snacks were measured continuously for the 12-month intervention. Price reductions of 10%, 25%, and 50% on low-fat snacks were associated with significant increases in low-fat snack sales; percentages of low-fat snack sales increased by 9%, 39%, and 93%, respectively. Promotional signage was independently but weakly associated with increases in low-fat snack sales. Average profits per machine were not affected by the vending interventions. Reducing relative prices on low-fat snacks was effective in promoting lower-fat snack purchases from vending machines in both adult and adolescent populations.

OBJECTIVES. This study evaluated the influence of age, gender, vending machine lockout devices, and tobacco industry-sponsored voluntary compliance programs ("It's the Law" programs) on underage youths' ability to purchase tobacco. METHODS. Twelve youths made 480 attempts to purchase tobacco in Massachusetts from over-the-counter retailers and vending machines with and without remote control lockout devices. Half the vendors were participating in It's the Law programs. RESULTS. In communities with no requirements for lockout devices, illegal sales were far more likely from vending machines than from over-the-counter sources (odds ratio [OR] = 5.9, 95% confidence interval [CI] = 3.3, 10.3). Locks on vending machines made them equivalent to over-the-counter sources in terms of illegal sales to youths. Vendors participating in It's the Law programs were as likely to make illegal sales as nonparticipants (OR = 0.87, 95% CI = 0.57, 1.35). Girls and youths 16 years of age and older were more successful at purchasing tobacco. CONCLUSIONS. The It's the Law programs are ineffective in preventing illegal sales. While locks made vending machines equivalent to over-the-counter sources in their compliance with the law, they are not a substitute for law enforcement. PMID:8633739

The current food environment has a high prevalence of nutrient-sparse foods and beverages, most starkly seen in vending machine offerings. There are currently few studies that explore different interventions that might lead to healthier vending machine purchases. To examine how healthier product availability, price reductions, and/or promotional signs affect sales and revenue of snack and beverage vending machines. A 2×2×2 factorial randomized controlled trial was conducted. Students, staff, and employees on a university campus. All co-located snack and beverage vending machines (n=56, 28 snack and 28 beverage) were randomized into one of eight conditions: availability of healthier products and/or 25% price reduction for healthier items and/or promotional signs on machines. Aggregate sales and revenue data for the 5-month study period (February to June 2015) were compared with data from the same months 1 year prior. Analyses were conducted July 2015. The change in units sold and revenue between February through June 2014 and 2015. Linear regression models (main effects and interaction effects) and t test analyses were performed. The interaction between healthier product guidelines and promotional signs in snack vending machines documented increased revenue (P<0.05). Beverage machines randomized to meet healthier product guidelines documented increased units sold (P<0.05) with no revenue change. Price reductions alone had no effect, nor were there any effects for the three-way interaction of the factors. Examining top-selling products for all vending machines combined, pre- to postintervention, we found an overall shift to healthier purchasing. When healthier vending snacks are available, promotional signs are also important to ensure consumers purchase those items in greater amounts. Mitigating potential loss in profits is essential for sustainability of a healthier food environment. Copyright © 2017 Academy of Nutrition and Dietetics. Published by Elsevier Inc.

Internationally, vending machines are scrutinized for selling energy-dense nutrient-poor foods and beverages, and the contribution to overconsumption and subsequent risk of obesity. The aim of this review is to determine the efficacy of nutrition interventions in vending machine in eliciting behaviour change to improve diet quality or weight status of consumers. Electronic databases Cochrane, EMBASE, CINAHL, Science Direct and PubMed were searched from inception. (i) populations that have access to vending machines; (ii) nutrition interventions; (iii) measured outcomes of behaviour change (e.g. sales data, dietary intake or weight change); and (iv) experimental trials where controls were not exposed to the intervention. Risk of bias was assessed independently by two researchers, and higher quality research formed the basis of this qualitative review. Twelve articles from 136 searched were included for synthesis. Intervention settings included schools, universities and workplaces. Reducing price or increasing the availability increased sales of healthier choices. The results of point-of-purchase nutrition information interventions were heterogeneous and when measured changes to purchases were small. This review offers evidence that pricing and availability strategies are effective at improving the nutritional quality foods and beverages purchased from vending machines. Evidence on how these interventions alter consumer's overall diet or body mass index is needed. © 2015 World Obesity.

[Card-based age control mechanisms at tobacco vending machines. Effect and consequences].

Schneider, S; Meyer, C; Löber, S; Röhrig, S; Solle, D

2010-02-01

Until recently, 700,000 tobacco vending machines provided uncontrolled access to cigarettes for children and adolescents in Germany. On January 1, 2007, a card-based electronic locking device was attached to all tobacco vending machines to prevent the purchase of cigarettes by children and adolescents under 16. Starting in 2009, only persons older than 18 are able to buy cigarettes from tobacco vending machines. The aim of the present investigation (SToP Study: "Sources of Tobacco for Pupils" Study) was to assess changes in the number of tobacco vending machines after the introduction of these new technical devices (supplier's reaction). In addition, the ways smoking adolescents make purchases were assessed (consumer's reaction). We registered and mapped the total number of tobacco points of sale (tobacco POS) before and after the introduction of the card-based electronic locking device in two selected districts of the city of Cologne. Furthermore, pupils from local schools (response rate: 83%) were asked about their tobacco consumption and ways of purchase using a questionnaire. Results indicated that in the area investigated the total number of tobacco POSs decreased from 315 in 2005 to 277 in 2007. The rates of decrease were 48% for outdoor vending machines and 8% for indoor vending machines. Adolescents reported circumventing the card-based electronic locking devices (e.g., by using cards from older friends) and using other tobacco POSs (especially newspaper kiosks) or relying on their social network (mainly friends). The decreasing number of tobacco vending machines has not had a significant impact on cigarette acquisition by adolescent smokers as they tend to circumvent the newly introduced security measures.

[Consumer's psychological processes of hoarding and avoidant purchasing after the Tohoku earthquake].

PubMed

Ohtomo, Shoji; Hirose, Yukio

2014-02-01

This study examined psychological processes of consumers that had determined hoarding and avoidant purchasing behaviors after the Tohoku earthquake within a dual-process model. The model hypothesized that both intentional motivation based on reflective decision and reactive motivation based on non-reflective decision predicted the behaviors. This study assumed that attitude, subjective norm and descriptive norm in relation to hoarding and avoidant purchasing were determinants of motivations. Residents in the Tokyo metropolitan area (n = 667) completed internet longitudinal surveys at three times (April, June, and November, 2011). The results indicated that intentional and reactive motivation determined avoidant purchasing behaviors in June; only intentional motivation determined the behaviors in November. Attitude was a main determinant of the motivations each time. Moreover, previous behaviors predicted future behaviors. In conclusion, purchasing behaviors were intentional rather than reactive behaviors. Furthermore, attitude and previous behaviors were important determinants in the dual-process model. Attitude and behaviors formed in April continued to strengthen the subsequent decisions of purchasing behavior.

2008-12-01

The household setting may be the most important level at which to understand the food choices of individuals and how healthful food choices can be promoted. However, there are few available measures of the food purchase behaviors of households and little consensus on the best way to measure it. This review explores the currently available measures of household food purchasing behavior. Three main measures are described, evaluated, and compared: home food inventories, food and beverage purchase records and receipts, and Universal Product Code bar code scanning. The development of coding, aggregation, and analytical methods for these measures of household food purchasing behavior is described. Currently, annotated receipts and records are the most comprehensive, detailed measure of household food purchasing behavior, and are feasible for population-based samples. Universal Product Code scanning is not recommended due to its cost and complexity. Research directions to improve household food purchasing behavior measures are discussed.

Council-supported condom vending machines: are they acceptable to rural communities?

Tomnay, Jane E; Hatch, Beth

2013-11-01

Twenty-four hour access to condoms for young people living in rural Victoria is problematic for many reasons, including the fact that condom vending machines are often located in venues and places they cannot access. We partnered with three rural councils to install condom vending machines in locations that provided improved access to condoms for local young people. Councils regularly checked the machines, refilled the condoms and retrieved the money. They also managed the maintenance of the machine and provided monthly data. In total, 1153 condoms were purchased over 12 months, with 924 (80%) obtained from male toilets and 69% (801 out of 1153) purchased in the second half of the study. Revenue of $2626.10 (AUD) was generated and no negative feedback from residents was received by any council nor was there any negative reporting by local media. Vandalism, tampering or damage occurred at all sites; however, only two significant episodes of damage required a machine to be sent away for repairs. Condom vending machines installed in rural towns in north-east Victoria are accessible to young people after business hours, are cost-effective for councils and have not generated any complaints from residents. The machines have not suffered unrepairable damage and were used more frequently as the study progressed.

2014-01-01

Background While cigarette purchasing behavior has been shown to be linked with certain tobacco use outcomes such as quit intentions and quit attempts, there have been very few studies examining cigarette purchasing behaviors and their impact on cigarette price and consumption in China, the world’s largest cigarette consumer. Objective The goal of this study is to examine the extent and determinants of cost/price-related purchase behaviors, and estimate the impact of these behaviors on cigarette prices paid by Chinese smokers. It also assesses the socio-economic differences in compensatory purchase behaviors, and examines how they influence the relationship between purchase behaviors, cigarette prices, and cigarette consumption. Methods Multivariate analyses using the general estimating equations (GEE) method were conducted using data from the International Tobacco Control China Survey (the ITC China Survey), a longitudinal survey of adult smokers in seven cities in China: Beijing, Changsha, Guangzhou, Kunming, Shanghai, Shenyang, and Yinchuan. In each city, about 800 smokers were surveyed in each wave. The first three waves - Wave 1 (conducted between March to December 2006), Wave 2 (November 2007 to March 2008) and Wave 3 (May to October 2009 and February to March 2010) - of the ITC China Survey data were used in this analysis. Various aspects of smokers’ self-reported price/cost-related cigarette purchasing behaviors were analyzed. Findings Nearly three-quarters (72%) of smokers surveyed indicated that a major reason they chose their most-used cigarette brand was its low cost/price. Almost half (50.6%) of smokers reported buying in cartons in their most recent cigarette purchase. Smokers with lower income and/or low levels of education were more likely to choose a brand because of its low cost/price. However, those with higher income and/or high levels of education were more likely to buy cartons. Gender and age were also related to type of purchase behaviors. Those behaviors led to reductions in purchase prices. The price savings ranged from 0.54 Yuan to 1.01 Yuan per pack of cigarettes, depending on the behavior examined, representing a price reduction of 8% - 15%. Conclusion A significant portion of Chinese urban adult smokers engaged in cost/price-reducing purchase behaviors. Such behaviors reduce cigarette purchase prices and are associated with increased cigarette consumption. Smokers of different SES engaged in different purchase behaviors to mitigate the impact of higher cigarette prices. Reducing tobacco use through raising tobacco taxes/prices in China needs to take into account these cost/price-reducing behaviors. PMID:24048580

Eating Away from Home: Influences on the Dietary Quality of Adolescents with Overweight or Obesity.

Watts, Allison W; Valente, Maria; Tu, Andrew; Mâsse, Louise C

2017-12-01

To examine the influence of peers and the source of meals and snacks on the dietary quality of adolescents seeking obesity treatment. Baseline surveys were completed by 173 adolescents with overweight or obesity (11-16 years old) enrolled in an e-health intervention in Vancouver, British Columbia. Dietary quality was assessed with three 24-h dietary recalls used to compute a Healthy Eating Index adapted to the Canadian context (HEI-C). Multiple linear regression examined associations between HEI-C scores and the frequency of: (i) meals prepared away from home, (ii) purchasing snacks from vending machines or stores, (iii) eating out with friends, and (iv) peers modeling healthy eating. Adolescents reported eating approximately 3 lunch or dinner meals prepared away from home and half purchased snacks from vending machines or stores per week. After adjusting for socio-demographics, less frequent purchases of snacks from vending machines or stores (b = -3.00, P = 0.03) was associated with higher HEI-C scores. More frequent dinner meals prepared away from home and eating out with friends were only associated with lower HEI-C scores in unadjusted models. Snack purchasing was associated with lower dietary quality among obesity treatment-seeking adolescents. Improving the healthfulness of foods obtained away from home may contribute to healthier diets among these adolescents.

An investigation of the association between vending machine confectionery purchase frequency by schoolchildren in the UK and other dietary and lifestyle factors.

2003-08-01

Availability of confectionery from vending machines in secondary schools provides a convenient point of purchase. There is concern that this may lead to 'over-indulgence' and hence an increase in susceptibility to obesity and poor 'dietary quality'. The study objective was to investigate the association between the frequency of consumption of confectionery purchased from vending machines and other sources and related lifestyle factors in adolescent boys and girls. A secondary school-based, cross-sectional study. A total of 504 subjects were investigated (age range 12-15 years), from three schools in southern and northern England. Using a lifestyle questionnaire, frequency of confectionery consumption (CC) from all sources (AS) and vending machines (VM) was recorded for a typical school week. Subjects were categorised into non-consumers, low, medium and high consumers using the following criteria: none, 0 times per week; low, 1-5 times per week; medium, 6-9 times per week; high, 10 times per week or greater. No differences were found in the frequency of CC from AS or VM between those who consumed breakfast and lunch and those who did not. No differences were found in the frequency of fruit and vegetable intake in high VM CC vs. none VM CC groups, or in any of the VM CC groups. Confectionery consumption from AS (but not VM) was found to be higher in subjects who were physically active on the journey to school (P<0.01) but also higher in those who spent more time watching television and playing computer games (P<0.01). No associations were found between smoking habits or alcohol consumption and frequency of CC. These results do not show a link between consumption of confectionery purchased from vending machines and 'poor' dietary practice or 'undesirable' lifestyle habits. Findings for total confectionery consumption showed some interesting trends, but the results were not consistent, either for a negative or positive effect.

2013-01-01

Taking advantage of a natural experiment made possible by the placement of health-promoting vending machines (HPVMs), we evaluated the impact of the intervention on consumers' attitudes toward and practices with vending machines in a pediatric hospital. Vending machines offering healthy snacks, meals, and beverages were developed to replace four vending machines offering the usual high-energy, low-nutrition fare. A pre- and post-intervention evaluation design was used; data were collected through exit surveys and six-week follow-up telephone surveys among potential vending machine users before (n=293) and after (n=226) placement of HPVMs. Chi-2 statistics were used to compare pre- and post-intervention participants' responses. More than 90% of pre- and post-intervention participants were satisfied with their purchase. Post-intervention participants were more likely to state that nutritional content and appropriateness of portion size were elements that influenced their purchase. Overall, post-intervention participants were more likely than pre-intervention participants to perceive as healthy the options offered by the hospital vending machines. Thirty-three percent of post-intervention participants recalled two or more sources of information integrated in the HPVM concept. No differences were found between pre- and post-intervention participants' readiness to adopt healthy diets. While the HPVM project had challenges as well as strengths, vending machines offering healthy snacks are feasible in hospital settings.

2016-12-01

Excess calorie intake from sugar-sweetened beverages (SSBs) and energy-dense, nutrient-poor foods occupies a significant proportion of Western diet. The aim of this study was to examine consumption of SSBs and discretionary foods in US adults by purchase location. Nationally representative 24-h dietary recall data came from the 2011-2012 National Health and Nutrition Examination Survey. The discretionary food category identifies energy-dense, nutrient-poor foods that do not necessarily contain essential nutrients but may add variety and enjoyment. Linear regressions were performed to estimate daily calorie intake from SSBs and discretionary foods by purchase location (supermarket/grocery store, convenience store, vending machine, fast-food restaurant, full-service restaurant and other source), adjusting for individual characteristics and sampling design. During 2011-2012, 46.3% and 88.8% of US adults consumed SSBs and discretionary foods on any given day, respectively. SSB consumers on average consumed 213.0 kcal from SSBs daily, of which 111.6 kcal (52.4%) were purchased from supermarkets/grocery stores, 33.0 kcal (15.5%) from fast-food restaurants, 23.9 kcal (11.2%) from convenience stores, 17.1 kcal (8.0%) from full-service restaurants, 8.5 kcal (4.0%) from vending machines and 19.0 kcal (8.9%) from other sources. Discretionary food consumers on average consumed 439.0 kcal from discretionary foods daily, of which 280.1 kcal (63.8%) were purchased from supermarkets/grocery stores, 45.8 kcal (10.4%) from fast-food restaurants, 30.0 kcal (6.8%) from full-service restaurants, 21.1 kcal (4.8%) from convenience stores, 4.1 kcal (0.9%) from vending machines and 58.0 kcal (13.2%) from other sources. Supermarkets/grocery stores were by far the single largest source for SSB and discretionary food purchases in US adults.

This study examined the availability of foods sold in vending machines and school stores in United States public and private schools, and associations of availability with students' food purchases and consumption. Descriptive analyses, chi-square tests, and Spearman product-moment correlations were conducted on data collected from 521 students aged 8 to 15 years recruited from orthodontic offices in California. Vending machines were more common in private schools than in public schools, whereas school stores were common in both private and public schools. The food items most commonly available in both vending machines and school stores in all schools were predominately foods of minimal nutritional value (FMNV). Participant report of availability of food items in vending machines and/or school stores was significantly correlated with (1) participant purchase of each item from those sources, except for energy drinks, milk, fruits, and vegetables; and (2) participants' friends' consumption of items at lunch, for 2 categories of FMNV (candy, cookies, or cake; soda or sports drinks). Despite the Child Nutrition and Women, Infants, and Children (WIC) Reauthorization Act of 2004, FMNV were still available in schools, and may be contributing to unhealthy dietary choices and ultimately to health risks. © 2015, American School Health Association.

Attitudes vs. Purchase Behaviors as Experienced Dissonance: The Roles of Knowledge and Consumer Orientations in Organic Market.

PubMed

Hidalgo-Baz, María; Martos-Partal, Mercedes; González-Benito, Óscar

2017-01-01

This research focuses on the incongruity between positive attitudinal responses but a lack of purchase behavior in organic markets. According to cognitive dissonance theory, consumer orientations toward the benefits attributed to organic products (environmental protection, health, hedonic) relieve the dissonance that results from this attitude-behavior incongruity. Knowledge also functions as a transmitter, from positive attitudes to purchase behaviors, thereby reducing the incongruity. Using quota sampling in a survey study, this paper tests the hypotheses from linear regression models. The results show that orientations and knowledge improve the congruity between attitudes and purchase behaviors toward organic products. Moreover, interaction effects arise between the environmental protection orientation and knowledge and between the hedonic orientation and knowledge. Increasing knowledge mitigates the difference between attitudes and purchase behaviors, especially for consumers with environmental protection or hedonic orientations. These findings have several important implications for research and practice.

Schutte, Nicola S; Bhullar, Navjot

2017-04-03

This paper describes a model focused on the role of self-efficacy and belief in changeability of behavior in motivating environmentally sustainable behavior. The model was tested in two studies. The first study found that participants who had greater self-efficacy for sustainability behavior and a greater belief in their changeability of sustainability behavior had a higher level of approach motivation toward sustainability behavior and reported more such actual behavior. The second study investigated the effect of brief interventions intended to increase perception of self-efficacy for sustainability-related purchasing and changeability of sustainability-related purchasing. The intervention that focused on enhancing self-efficacy for making sustainability-related purchases had the strongest impact on intention to purchase. These findings have implications for interventions intended to change behavior related to environmental sustainability.

This study examined the relationship between the neighborhood food environment and the food purchasing behaviors among adolescents. Grade 7 and 8 students (n = 810) at 21 elementary schools in London, Ontario, Canada completed a questionnaire assessing their food purchasing behaviors. Parents of participants also completed a brief questionnaire providing residential address and demographic information. A Geographic Information System (GIS) was used to assess students' home and school neighborhood food environment and land use characteristics. Logistic regression analysis was conducted to assess the influence of the home neighborhood food environment on students' food purchasing behaviors, while two-level Hierarchical Non-Linear Regression Models were used to examine the effects of school neighborhood food environment factors on students' food purchasing behaviors. The study showed that approximately 65% of participants reported self-purchasing foods from fast-food outlets or convenience stores. Close proximity (i.e., less than 1 km) to the nearest fast-food outlet or convenience store in the home neighborhood increased the likelihood of food purchasing from these food establishments at least once per week by adolescents (p < 0.05). High fast-food outlet density in both home and school neighborhoods was associated with increased fast-food purchasing by adolescents (i.e., at least once per week; p < 0.05). In conclusion, macro-level regulations and policies are required to amend the health-detracting neighborhood food environment surrounding children and youth's home and school.

2014-07-01

Small employers are underserved with workplace health promotion services, so we explored the potential for group purchasing of these services. We conducted semistructured telephone interviews of member organizations serving small employers, as well as workplace health promotion vendors, in Washington State. We interviewed 22 employer organizations (chambers of commerce, trade associations, and an insurance trust) and vendors (of fitness facilities, healthy vending machines, fresh produce delivery, weight management services, and tobacco cessation quitlines). Both cautiously supported the idea of group purchasing but felt that small employers' workplace health promotion demand must increase first. Vendors providing off-site services, for example, quitline, found group purchasing more feasible than vendors providing on-site services, for example, produce delivery. Employer member organizations are well-positioned to group purchase workplace health promotion services; vendors are receptive if there is potential profit.

(i) To audit the nutritional composition, promotion and cost of products available from vending machines available to young adults; and (ii) to examine the relationship between product availability and sales. A cross-sectional analysis of snacks and beverages available and purchased at a large urban university was conducted between March and September 2014. Sales were electronically tracked for nine months. A total of 61 vending machines were identified; 95% (n = 864) of the available snacks and 49% of beverages (n = 455) were less-healthy items. The mean (SD) nutrient value of snacks sold was: energy 1173 kJ (437.5), saturated fat 5.36 g (3.6), sodium 251 mg (219), fibre 1.56 g (1.29) and energy density 20.16 kJ/g (2.34) per portion vended. There was a strong correlation between the availability of food and beverages and purchases (R 2 = 0.98, P < 0.001). Vending machines market and sell less-healthy food and beverages to university students. Efforts to improve the nutritional quality are indicated and afford an opportunity to improve the diet quality of young adults, a group at risk of obesity. © 2016 Dietitians Association of Australia.

The 'third class' of medications: Sales and purchasing behavior are associated with pharmacist only and pharmacy medicine classifications in Australia.

Emmerton, Lynne

2009-01-01

Nonprescription (over-the-counter) medications in Australia are classified as Pharmacist Only Medicines, Pharmacy Medicines, or unscheduled medications. This report characterizes these medication classifications using key sales and purchasing behavior variables. Descriptive, nonexperimental, cross-sectional study. 15 pharmacies in southeast Queensland, Australia, with data recorded over 36 hours per pharmacy in mid-August, 2006. Eligible purchasers (n = 3,470 medication purchases) of all nonprescription medications (including nutritional supplements). Researchers documented details of all observed nonprescription medication sales and interviewed all available patients following the transaction. Incidence of product-related consultation, products purchased (brand, dosage form, classification), and purchasing behavior data (including previous purchase, intended use, intended user, and intention to purchase a particular brand). More restrictive classification of the purchased medication was significantly (P < 0.01) associated with younger purchasers, purchase of a single nonprescription medication, intent to self-use the medication, intent to purchase a particular brand, repeat purchase, brand-switching interventions by pharmacy staff, pharmacy staff influence on first-time purchases, and observed consultation by pharmacists. Legislative compliance issues were identified: Pharmacists consulted in only 54.7% of Pharmacist Only Medicine sales and 13 cases (1.7% of observed sales) occurred in which Pharmacist Only and Pharmacy Medicines had been sourced from publicly accessible areas of the store. Pharmacist Only Medicines received greater levels of professional involvement during their sale than Pharmacy Medicines and unscheduled medications, despite higher levels of product familiarity among patients. To optimize the benefits of this classification system, emphasis on professional guidelines is recommended.

Burgardt, Paul; Pierce, Stanley W.

The purpose of this paper is to present and discuss data related to the performance of a newly acquired low voltage electron beam welding machine. The machine was made by Pro-Beam AG &Co. KGaA of Germany. This machine was recently installed at LANL in building SM -39; a companion machine was installed in the production facility. The PB machine is substantially different than the EBW machines typically used at LANL and therefore, it is important to understand its characteristics as well as possible. Our basic purpose in this paper is to present basic machine performance data and to compare thosemore » with similar results from the existing EBW machines. It is hoped that this data will provide a historical record of this machine’s characteristics as well as possibly being helpful for transferring welding processes from the old EBW machines to the PB machine or comparable machines that may be purchased in the future.« less

Supermarket Choice, Shopping Behavior, Socioeconomic Status, and Food Purchases

Pechey, Rachel; Monsivais, Pablo

2015-01-01

Introduction Both SES and supermarket choice have been associated with diet quality. This study aimed to assess the contributions of supermarket choice and shopping behaviors to the healthfulness of purchases and social patterning in purchases. Methods Observational panel data on purchases of fruit and vegetables and less-healthy foods/beverages from 2010 were obtained for 24,879 households, stratified by occupational social class (analyzed in 2014). Households’ supermarket choice was determined by whether they ever visited market-defined high- or low-price supermarkets. Analyses also explored extent of use within supermarket choice groups. Shopping behaviors included trip frequency, trip size, and number of store chains visited. Results Households using low-price (and not high-price) supermarkets purchased significantly lower percentages of energy from fruit and vegetables and higher percentages of energy from less-healthy foods/beverages than households using high-price (and not low-price) supermarkets. When controlling for SES and shopping behaviors, the effect of supermarket choice was reduced but remained significant for both fruit and vegetables and less-healthy foods/beverages. The extent of use of low- or high-price supermarkets had limited effects on outcomes. More-frequent trips and fewer small trips were associated with healthier purchasing for both outcomes; visiting more store chains was associated with higher percentages of energy from fruit and vegetables. Conclusions Although both supermarket choice and shopping behaviors are associated with healthfulness of purchases, neither appears to contribute to socioeconomic differences. Moreover, differences between supermarket environments may not be primary drivers of the relationship between supermarket choice and healthfulness of purchases. PMID:26163172

2015-08-01

We examined loose cigarette (loosie) purchasing behavior among young adult (aged 18-26 years) smokers at bars in New York City and factors associated with purchase and use. Between June and December 2013, we conducted cross-sectional surveys (n = 1916) in randomly selected bars and nightclubs. Using multivariable logistic regression models, we examined associations of loose cigarette purchasing and use with smoking frequency, price, social norms, cessation behaviors, and demographics. Forty-five percent (n = 621) of nondaily smokers and 57% (n = 133) of daily smokers had ever purchased a loosie; 15% of nondaily smokers and 4% of daily smokers reported that their last cigarette was a loosie. Nondaily smokers who never smoked daily were more likely than were daily smokers to have last smoked a loosie (odds ratio = 7.27; 95% confidence interval = 2.35, 22.48). Quitting behaviors and perceived approval of smoking were associated with ever purchasing and recently smoking loosies. Loosie purchase and use is common among young adults, especially nondaily smokers. Smoking patterns and attitudes should be considered to reduce loose cigarette purchasing among young adults in New York City.

Behavioral Economics of Cigarette Purchase Tasks: Within-Subject Comparison of Real, Potentially Real, and Hypothetical Cigarettes

PubMed Central

Wilson, A. George; Franck, Christopher T.; Koffarnus, Mikhail N.

2016-01-01

Abstract Introduction: Hypothetical rewards are commonly used in studies of laboratory-based tobacco demand. However, behavioral economic demand procedures require confirmation that the behavior elicited from real and hypothetical reward types are equivalent, and that results attained from these procedures are comparable to other accepted tasks, such as the hypothetical purchase task. Methods: Nineteen smokers were asked to purchase 1 week’s worth of cigarettes that they would consume over the following week either at one price that incrementally increased across four weekly sessions (“real” sessions) or four prices in a single session (“potentially real” session), one of which was randomly chosen to be actualized. At each session, participants also completed a hypothetical cigarette purchase task. After each week, participants reported the number of cigarettes they actually smoked. Results: Demand was found to be equivalent under both the real and potentially real reward conditions but statistically different from the demand captured in the hypothetical purchase task. However, the amounts purchased at specific prices in the hypothetical purchase task were significantly correlated with the amount purchased at comparable prices in the other two tasks (except for the highest price examined in both tasks of $1.00 per cigarette). Number of cigarettes consumed that were obtained outside of the study was correlated with study cigarette price. Conclusions: Combined, these results suggest that purchasing behavior during potentially real sessions (1) was not functionally different from real sessions, (2) imposes fewer costs to the experimenter, and (3) has high levels of both internal and external validity.

Objective: To systematically review evidence from field interventions on the effectiveness of monetary subsidies in promoting healthier food purchases and consumption. Design: Keyword and reference search were conducted in 5 electronic databases: Cochrane Library, EconLit, MEDLINE, PsycINFO, and Web of Science. Studies were included based on the following criteria – intervention: field experiments; population: adolescents 12-17 years old or adults 18 years and older; design: randomized controlled trials, cohort studies, or pre-post studies; subsidy: price discounts or vouchers for healthier foods; outcome: food purchases or consumption; period: 1990-2012; and language: English. Twenty-four articles on 20 distinct experiments were included with study quality assessed using predefined methodological criteria. Setting: Interventions were conducted in 7 countries: USA (n 14), New Zealand (n 1), France (n 1), Germany (n 1), Netherlands (n 1), South Africa (n 1), and United Kingdom (n 1). Subsidies applied to different types of foods such as fruits, vegetables, and low-fat snacks sold in supermarket, cafeteria, vending machine, farmers' market, or restaurant. Subjects: Interventions enrolled various population subgroups such as school/university students, metropolitan transit workers, and low-income women. Results: All but one study found subsidies on healthier foods to significantly increase the purchase and consumption of promoted products. Study limitations include small and convenience samples, short intervention and follow-up duration, and lack of cost-effectiveness and overall diet assessment. Conclusions: Subsidizing healthier foods tends to be effective in modifying dietary behavior. Future studies should examine its long-term effectiveness and cost-effectiveness at the population level and its impact on overall diet intake. PMID:23122423

To examine psychosocial and demographic variables associated with consumer intention to purchase sustainably produced foods using an expanded Theory of Planned Behavior. Consumers were approached at the store entrance and asked to complete a self-administered survey. Three metropolitan Minnesota grocery stores. Participants (n = 550) were adults who shopped at the store: the majority were white, female, and highly educated and earned >or= 50,000 dollars/year. Participation rates averaged 62%. The major domain investigated was consumer support for sustainably produced foods. Demographics, beliefs, attitudes, subjective norm, and self-identity and perceived behavioral control were evaluated as predictors of intention to purchase them. Descriptive statistics, independent t tests, one-way analysis of variance, Pearson product moment correlation coefficients, and stepwise multiple regression analyses (P <.05). Consumers were supportive of sustainably produced foods but not highly confident in their ability to purchase them. Independent predictors of intention to purchase them included attitudes, beliefs, perceived behavioral control, subjective norm, past buying behavior, and marital status. Beliefs, attitudes, and confidence level may influence intention to purchase sustainably produced foods. Nutrition educators could increase consumers' awareness of sustainably produced foods by understanding their beliefs, attitudes, and confidence levels.

This study compares the mechanical properties of modified Kessler and double-modified Kessler flexor tendon repair techniques and evaluates simple modifications on both methods. Forty fresh sheep flexor tendons were divided equally into four groups. A transverse sharp cut was done in the middle of each tendon and then repaired with modified Kessler technique, modified Kessler with additional purchase point in the midpoint of each longitudinal strand, double-modified Kessler technique, or a combination of outer Kessler and inner cruciate configuration based on double-modified Kessler technique. The tendons were tested in a tensile testing machine to assess the mechanical performance of the repairs. Outcome measures included gap formation and ultimate forces. The gap strengths of the double-modified Kessler technique (30.85 N, SD 1.90) and double-modified Kessler technique with inner cruciate configuration (33.60 N, SD 4.64) were statistically significantly greater than that of the two-strand modified Kessler (22.56 N, SD 3.44) and modified Kessler with additional purchase configuration (21.75 N, SD 4.03; Tukey honestly significant difference test, P < 0.000). There were statistically significant differences in failure strengths of the all groups (analysis of variance, P < 0.000). With an identical number of strands, the gap formation and ultimate forces of the repairs were not changed by additional locking purchase point in modified Kessler repair or changing the inner strand configuration in double-modified Kessler repair. The results of this study show that the number of strands across the repair site together with the number of locking loops clearly affects the strength of the repair; meanwhile, the longitudinal strand orientation and number of purchase points in a single loop did not affect its strength.

To examine whether several food purchasing behaviors (ie, sources of meals or snacks) are associated with adolescents' sugar-sweetened beverage (SSB) consumption and whether these associations vary by province. Cross-sectional observational study. Alberta and Ontario, Canada. Secondary school students from Alberta (n = 3,300) and Ontario (n = 37,999) participating in year 2 (2013-2014) of the Cannabis Use, Obesity, Mental Health, Physical Activity, Alcohol Use, Smoking, Sedentary Behavior (COMPASS) study. Participants' self-reported frequency of consuming 3 SSB types (soft drinks, sweetened coffees/teas, and energy drinks) in a typical week. Hierarchical Poisson regression analyses. Participants from Alberta had a significantly (P < .05) higher rate of consuming SSBs and purchasing meals or snacks from school food outlets compared with their Ontario counterparts. Most of the food purchasing behaviors were significantly (P < .05) and positively associated with greater rates of SSB consumption. Meal or snack purchases on weekends (vs weekdays) and from food outlets off school property (vs on school property) had a greater association with SSB consumption. Eating a home-packed lunch was protective against SSB consumption across models. Adolescents' food purchasing behaviors have a significant impact on their propensity for SSB consumption. These data demonstrate potentially important contexts for SSB consumption and have implications for possible settings and strategies for future interventions to reduce adolescents' SSB intake.

National, state, and local institutions that procure, distribute, sell, and/or serve food to employees, students, and the public are increasingly capitalizing on existing operational infrastructures to create healthier food environments. Integration of healthy nutrition standards and other recommended practices [e.g., energy (kilocalories) postings at point-of-purchase, portion size restrictions, product placement guidelines, and signage] into new or renewing food service and vending contracts codifies an institution's commitment to increasing the availability of healthful food options in their food service venues and vending machines. These procurement requirements, in turn, have the potential to positively influence consumers' food-purchasing behaviors. Although these strategies are becoming increasingly popular, much remains unknown about their context, the processes required to implement them effectively, and the factors that facilitate their sustainability, especially in such broad and diverse settings as schools, county government facilities, and cities. To contribute to this gap in information, we reviewed and compared nutrition standards and other best practices implemented recently in a large school district, in a large county government, and across 10 municipalities in Los Angeles County. We report lessons learned from these efforts.

To assess the short- and long-term effects of an AIDS-prevention workshop on undergraduates' attitudes about condom use and AIDS, 31 participants and 31 controls were studied immediately after training sessions as well as three months later. The workshop was aimed at reducing embarrassment to purchase condoms, encouraging positive attitudes about condoms, and promoting knowledge about AIDS. To help students overcome their embarrassment over condom purchases, a behavioral intervention was included allowing students to make condom purchases at nearby drug stores. Results revealed that participants reported less embarrassment over condom purchases after training sessions and that this effect became even stronger over time. Knowledge about AIDS and positive attitudes about condoms also increased immediately after the workshop, but these changes did not persist. Results suggest that AIDS prevention workshops may lead to transient changes unless a specific skill (i.e., condom purchasing) is targeted via behavioral training.

Although inverter-based welding power sources have been available since the late 1980s, many people hesitated to purchase them because of reliability issues. Unfortunately, their hesitancy had a basis, until now. Recent improvements give some inverters a reliability level that approaches that of traditional, transformer-based industrial welding machines, which have a failure rate of about 1%. Acceptance of inverter-based welding machines is important because, for many welding applications, they provide capabilities that solid-state, transformer-based machines cannot deliver. These advantages include enhanced pulsed gas metal arc welding (GMAW-P), lightweight portability, an ultrastable arc, and energy efficiency--all while producing highly aesthetic weld beadsmore » and delivering multiprocess capabilities.« less

Chen, Weiping; Scott, Steffanie

2014-12-01

This study explores the concept of perceived embeddedness (PE) and its impact on purchasing behavior at an organic farmers' market. Based on a review of the prior literature, the study refines the conceptualization and measurement of PE as a second-order factor construct reflected in its three dimensions: perceived social embeddedness, perceived spatial embeddedness, and perceived natural embeddedness. The study also suggests that organic farmers' market shoppers' PE is positively related to the two measures of purchasing behavior: expenditure per visit and repurchase intention. In a sample of 492 organic farmers' market shoppers in Beijing municipality, China, the study find support for the second-order factor structure of PE and the theorized relationship between the shoppers' PE and their purchasing behavior. The study also discusses theoretical and managerial implications of the findings. Copyright © 2014 Elsevier Ltd. All rights reserved.

Restaurant initiatives provide an efficient opportunity to impact large numbers of patrons. The purpose of this study is to measure patron purchasing behaviors during the ¡Por Vida! menu designation initiative. This study used a cross-sectional design and survey data to assess 23 restaurants throughout Bexar County and 152 restaurant patrons. The Patron Awareness Questionnaire assessed if patrons noticed the logo; believed nutrition, cost, and taste were important in making purchasing decisions; and purchased a ¡Por Vida! item. Descriptive statistics, Spearman correlations, and logistic regression were used to analyze the data. Most (93.4%) patrons considered taste very important when deciding what to eat. Cost was very important to 63.8% and nutrition was very important to 55.9% of the sample. The strongest predictors of purchasing a ¡Por Vida! item were the patrons' ages being between 18 and 35 years (odds ratio = 1.474; confidence interval = 0.017, 0.812; p < .05) and if patrons saw the logo (odds ratio = 4.327; confidence interval = 1.696-11.036; p < .01). Menu logo designation initiatives can potentially influence patron purchasing behaviors among a segment of the population when the logo is visible.

Stimulus selectivity of drug purchase tasks: A preliminary study evaluating alcohol and cigarette demand.

PubMed

Strickland, Justin C; Stoops, William W

2017-06-01

The use of drug purchase tasks to measure drug demand in human behavioral pharmacology and addiction research has proliferated in recent years. Few studies have systematically evaluated the stimulus selectivity of drug purchase tasks to demonstrate that demand metrics are specific to valuation of or demand for the commodity under study. Stimulus selectivity is broadly defined for this purpose as a condition under which a specific stimulus input or target (e.g., alcohol, cigarettes) is the primary determinant of behavior (e.g., demand). The overall goal of the present study was to evaluate the stimulus selectivity of drug purchase tasks. Participants were sampled from the Amazon.com's crowdsourcing platform Mechanical Turk. Participants completed either alcohol and soda purchase tasks (Experiment 1; N = 139) or cigarette and chocolate purchase tasks (Experiment 2; N = 46), and demand metrics were compared to self-reported use behaviors. Demand metrics for alcohol and soda were closely associated with commodity-similar (e.g., alcohol demand and weekly alcohol use) but not commodity-different (e.g., alcohol demand and weekly soda use) variables. A similar pattern was observed for cigarette and chocolate demand, but selectivity was not as consistent as for alcohol and soda. Collectively, we observed robust selectivity for alcohol and soda purchase tasks and modest selectivity for cigarette and chocolate purchase tasks. These preliminary outcomes suggest that demand metrics adequately reflect the specific commodity under study and support the continued use of purchase tasks in substance use research.

2015-01-01

As regulation of tobacco products tightens, there are concerns that illicit markets may develop to supply restricted products. However, there are few validated measures to assess attitudes or purchase intentions toward contraband tobacco (CT). As such, it is important to investigate individual level characteristics that are associated with the purchase and use of contraband tobacco. In May 2013, a pilot survey assessed attitudes, behaviors, and purchase intentions for contraband tobacco based on previous research regarding non-tobacco contraband. The survey was administered via Amazon Mechanical Turk, a crowdsourcing resource, among current smoking respondents in the United States and Canada. Structural equation modeling was used to evaluate the validity of the proposed model for understanding attitudes toward contraband tobacco. CT purchasers were more likely to report norms supportive of counterfeit products, more intentions toward purchasing counterfeit products, a lowered risk associated with these products, and to have more favorable attitudes toward CT than those who had not purchased CT. Attitudes toward CT mediated the relationship between subjective norms and prior purchase with behavior intentions. Perceived risk had a significant direct effect on intentions and an indirect effect through attitudes toward CT. The structural model fit the data well and accounted for over half (53%) of the variance in attitudes toward tobacco. Understanding the mechanisms associated with CT attitudes and purchase behaviors may provide insight for how to mitigate possible iatrogenic consequences of newly implemented regulations. The measures developed here elucidate some elements that influence attitudes and purchase intentions for CT and may inform policy efforts to curtail the development of illicit markets.

Purchased Behavioral Health Care Received by Military Health System Beneficiaries in Civilian Medical Facilities, 2000-2014.

Behavioral health conditions are a significant concern for the U.S. military and the Military Health System (MHS) because of decreased military readiness and increased health care utilization. Although MHS beneficiaries receive direct care in military treatment facilities, a disproportionate majority of behavioral health treatment is purchased care received in civilian facilities. Yet, limited evidence exists about purchased behavioral health care received by MHS beneficiaries. This longitudinal study (1) estimated the prevalence of purchased behavioral health care and (2) identified patient and visit characteristics predicting receipt of purchased behavioral health care in acute care facilities from 2000 to 2014. Medical claims with Major Diagnostic Code 19 (mental disorders/diseases) or 20 (alcohol/drug disorders) as primary diagnoses and TRICARE as the primary/secondary payer were analyzed for MHS beneficiaries (n = 17,943) receiving behavioral health care in civilian acute care facilities from January 1, 2000, to December 31, 2014. The primary dependent variable, receipt of purchased behavioral health care, was modeled for select mental health and substance use disorders from 2000 to 2014 using generalized estimating equations. Patient characteristics included time, age, sex, and race/ethnicity. Visit types included inpatient hospitalization and emergency department (ED). Time was measured in days and visits were assumed to be correlated over time. Behavioral health care was described by both frequency of patients and visit type. The University of South Carolina Institutional Review Board approved this study. From 2000 to 2014, purchased care visits increased significantly for post-traumatic stress disorder, adjustment, anxiety, mood, bipolar, tobacco use, opioid/combination opioid dependence, nondependent cocaine abuse, psychosocial problems, and suicidal ideation among MHS beneficiaries. The majority of care was received for mental health disorders (78.8%) and care was most often received in EDs (56%). Most commonly treated diagnoses included mood, tobacco use, and alcohol use disorders. ED visits were associated with being treated for anxiety (excluding post-traumatic stress disorder; Adjusted odds ratio [AOR]: 9.14 [95% confidence interval (CI): 8.26, 10.12]), alcohol use disorders (AOR = 1.67 [95% CI: 1.53, 1.83]), tobacco use (AOR = 1.16 [95% CI: 1.06, 1.26]), nondependent cocaine abuse (AOR = 5.47 [95% CI: 3.28, 9.12]), nondependent mixed/unspecified drug abuse (AOR = 7.30 [95% CI: 5.11, 10.44]), and psychosis (AOR = 1.38 [95% CI: 1.20, 1.58]). Compared with adults age 60 yr and older, adolescents (ages 12-17 yr), and adults under age 60 yr were more likely to be treated for suicidal ideation, adjustment, mood, bipolar, post-traumatic stress disorder, nondependent cocaine, and mixed/unspecified drug abuse. Adults under age 60 yr also had increased odds of being treated for tobacco use disorders, alcohol use disorders, and opioid/combination opioid dependence compared with adults age 60 yr and older. Over the past 15 yr, purchased behavioral health care received by MHS beneficiaries in acute care facilities increased significantly. MHS beneficiaries received the majority of purchased behavioral health care for mental health disorders and were treated most often in the ED. Receiving behavioral health care in civilian EDs raises questions about access to outpatient behavioral health care and patient-centered care coordination between civilian and military facilities. Given the influx of new Veterans Health Administration users from the MHS, findings have implications for military, veteran, and civilian facilities providing behavioral health care to military and veteran populations. © Association of Military Surgeons of the United States 2018.

Cocaine behavioral economics: From the naturalistic environment to the controlled laboratory setting

PubMed Central

Greenwald, Mark K.; Steinmiller, Caren L.

2017-01-01

Background We previously observed that behavioral economic factors predict naturalistic heroin seeking behavior that correlates with opioid seeking in the experimental laboratory. The present study sought to replicate and extend these prior findings with regular cocaine users. Methods Participants (N = 83) completed a semi-structured interview to establish income-generating and cocaine-purchasing/use repertoire during the past month. Questions addressed sources/amounts of income and expenditures; price (money and time) per purchase; and frequency/amounts of cocaine purchased and consumed. Naturalistic cocaine purchasing and use patterns were: (1) analyzed as a function of income quartile, (2) perturbed by hypothetical changes in cost factors to assess changes in purchasing/use habits, and (3) correlated with experimental cocaine seeking. Results Income was positively related to naturalistic cocaine seeking/use pattern (i.e., income elastic), and behaviors were cost-efficient and sensitive to supply chain. Income was unrelated to proportional expenditure on cocaine (≈55%) but inversely related to food expenditure. In all hypothetical scenarios (changes in income or dealer, loss of income assistance from government or family/friends, and increasing arrest risk when purchasing), the high-income group reported they would continue to use more cocaine daily than other groups. Number of laboratory cocaine choices significantly correlated with cocaine purchase time (positively) and purity of cocaine (negatively) in the naturalistic setting. Conclusions These results replicate and extend findings with regular heroin users, demonstrate the importance of income, cost-efficiency and supply-mindedness in cocaine seeking/use, and suggest that this interview-based approach has good external validity.

Implementing Audio-CASI on Windows’ Platforms

PubMed Central

Cooley, Philip C.; Turner, Charles F.

2011-01-01

Audio computer-assisted self interviewing (Audio-CASI) technologies have recently been shown to provide important and sometimes dramatic improvements in the quality of survey measurements. This is particularly true for measurements requiring respondents to divulge highly sensitive information such as their sexual, drug use, or other sensitive behaviors. However, DOS-based Audio-CASI systems that were designed and adopted in the early 1990s have important limitations. Most salient is the poor control they provide for manipulating the video presentation of survey questions. This article reports our experiences adapting Audio-CASI to Microsoft Windows 3.1 and Windows 95 platforms. Overall, our Windows-based system provided the desired control over video presentation and afforded other advantages including compatibility with a much wider array of audio devices than our DOS-based Audio-CASI technologies. These advantages came at the cost of increased system requirements --including the need for both more RAM and larger hard disks. While these costs will be an issue for organizations converting large inventories of PCS to Windows Audio-CASI today, this will not be a serious constraint for organizations and individuals with small inventories of machines to upgrade or those purchasing new machines today.

Turning point for US diets? Recessionary effects or behavioral shifts in foods purchased and consumed.

PubMed

2014-03-01

In the past decade, the United States has seen declining energy intakes and plateauing obesity levels. We examined whether these observed trends suggest a longer-term shift in dietary and health behavior that is independent of adverse economic conditions. We used nationally representative cross-sectional surveys on intake and longitudinal household food purchase data along with random-effects models to address this question. Data included individuals in NHANES 2003-2004 to 2009-2010 (children: n = 13,422; adults: n = 10,791) and households from the 2000-2011 Nielsen Homescan Panel (households with children: n = 57,298; households with adults only: n = 108,932). In both data sets, we showed that children decreased their calories the most. Even after we controlled for important socioeconomic factors, caloric purchases fell significantly from 2003 to 2011 (P < 0.001), particularly for households with children. The Great Recession was associated with small increases in caloric purchases, in which a 1-percentage point increase in unemployment in the local market was associated with a 1.6-4.1-kcal · capita⁻¹ · d⁻¹ (P < 0.001) increase in total calories purchased. Results also indicated shifts in caloric purchases were driven more by declines in caloric purchases from beverages than food. US consumers have exhibited changes in intake and purchasing behavior since 2003 that were independent from changing economic conditions linked with the Great Recession or food prices. Public health efforts in the past decade may have contributed to this trend.

Pricing effects on food choices.

PubMed

French, Simone A

2003-03-01

Individual dietary choices are primarily influenced by such considerations as taste, cost, convenience and nutritional value of foods. The current obesity epidemic has been linked to excessive consumption of added sugars and fat, as well as to sedentary lifestyles. Fat and sugar provide dietary energy at very low cost. Food pricing and marketing practices are therefore an essential component of the eating environment. Recent studies have applied economic theories to changing dietary behavior. Price reduction strategies promote the choice of targeted foods by lowering their cost relative to alternative food choices. Two community-based intervention studies used price reductions to promote the increased purchase of targeted foods. The first study examined lower prices and point-of-purchase promotion on sales of lower fat vending machine snacks in 12 work sites and 12 secondary schools. Price reductions of 10%, 25% and 50% on lower fat snacks resulted in an increase in sales of 9%, 39% and 93%, respectively, compared with usual price conditions. The second study examined the impact of a 50% price reduction on fresh fruit and baby carrots in two secondary school cafeterias. Compared with usual price conditions, price reductions resulted in a four-fold increase in fresh fruit sales and a two-fold increase in baby carrot sales. Both studies demonstrate that price reductions are an effective strategy to increase the purchase of more healthful foods in community-based settings such as work sites and schools. Results were generalizable across various food types and populations. Reducing prices on healthful foods is a public health strategy that should be implemented through policy initiatives and industry collaborations.

Loyalty programs are a consolidated marketing instrument whose adoption in many sectors has not been associated with appropriate comprehension of either their management elements or their effects. The purpose of this research is to contribute to knowledge about the effect of loyalty programs on repeat purchase behavior. More specifically, it seeks to discover whether joining a program changes the buying behavior of its members, and, if so, to study the profile of those whose behavior changes most. The intention was also to provide new study variables pertaining to multi-vendor loyalty programs, such as where they are joined or purchases in associated outlets as a result of behavioral loyalty. Research was carried out using a sample of 1200 individuals (31,746 purchases) belonging to a multi-vendor loyalty program. The study period was 13 years, 4 months, and split into two phases: before and after the joining the program. Different methodological approaches, such as the use of transactional databases that included pre-program-enrollment data and of the same sampling units throughout the study, were incorporated into the research with the aim of advancing academic knowledge regarding multi-vendor loyalty programs. Moreover, a type of program and market hardly dealt with in the relevant literature was analyzed. The results showed while the loyalty program had managed to reduce the time between purchases, it had not affected purchase volume or average expenditure. They also demonstrated the existence of a differential profile of customers who had changed their buying behavior to a greater extent. Finally, recency was identified as being the decisive variable in behavioral change.

By analyzing a huge amount of point-of-sale data collected from Japanese supermarkets, we find power law relationships between price and sales numbers. The estimated values of the exponents of these power laws depend on the category of products; however, they are independent of the stores, thereby implying the existence of universal human purchase behavior. The rate of sales numbers around these power laws are generally approximated by log-normal distributions implying that there are hidden random parameters, which might proportionally affect the purchase activity.

1991-01-01

Investigating the nature and degree of female household decision-making in Pakistan, this paper analyzes the influence of women in the purchase consumer durables. The paper also identifies those factors which enable women to play a more active role in the decision-making process. Because women in Pakistan are generally excluded from the public sphere, their level of emancipation is better assessed according to the degree of participation in household decision-making. A good measure of women's power within a household is their influence in the purchase of consumer durables (cars, appliances, etc.), whose expense and life-long nature makes their purchase an important decision. For this study, the authors relied on data from a 1989 nationwide household survey conducted by AERC, which included a information concerning the acquisition of 12 consumer durables as expected. As expected, men make more decisions on the purchase of all consumer goods than women, even for items in which women feel more need than men (e.g. sewing machines, washing machines). The study found that for the needs felt by women for all durable goods, men make 2/3 of all decisions, while women make only 1/3 of decisions. And in cases where the need is felt by men, the men make 93% of the decisions, while women decide only 3 % of the times. The study identified various cultural and economic factors that affect women's decision making power: urban women, women in nuclear families, educated women, and working women generally have more decision making power than rural women, women in extended families, illiterate women, and unemployed women.

The purpose of the present study was to investigate the relative importance of adolescents' attitude toward an act (the degree to which the person had a favorable or unfavorable evaluation or appraisal of the act's behavior in question), perceived norm, and perceived behavioral control in predicting Taiwanese adolescents' intention to purchase the merchandise of a celebrity when they had different levels of celebrity adoration. The present results showed that the relative strengths of attitude toward the act and the perception of behavioral control in predicting purchase intention toward the merchandise of a celebrity were stronger for adolescents in the celebrity adoration group than for adolescents in the celebrity nonadoration group. On the other hand, the relative importance of the perceived norm in predicting the attitude toward the act and the purchase intention was stronger for adolescents in the celebrity nonadoration group than for adolescents in the celebrity adoration group.

Variety seeking in the consumption of spread and cheese.

PubMed

Van Trijp, H C; Lähteenmäki, L; Tuorila, H

1992-04-01

Consumers' (n = 807) desire for variety, as measured by the food-specific VARSEEK scale, was related to reported usage and purchase behavior for spread and cheese. Subjects' scoring high in variety seeking tendency showed more exploratory tendencies in purchase behavior, vicarious exploration and use innovativeness than did those scoring low on the scale. Variation reported in the use of cheese was related to variety seeking tendency more strongly than the variation in the use of spreads. The variation in cheese purchases was particularly high for well-educated white collar workers between 31 and 50 years old and for female subjects living in urban areas of Finland. Some cross-product consistency in the variation in purchase behavior was found. The results suggest that certain product characteristics, such as sensory variation between alternatives, may determine whether the intrinsic desire for variety is expressed in product choice.

Predictability in Pathological Gambling? Applying the Duplication of Purchase Law to the Understanding of Cross-Purchases Between Regular and Pathological Gamblers.

PubMed

Lam, Desmond; Mizerski, Richard

2017-06-01

The objective of this study is to explore the gambling participations and game purchase duplication of light regular, heavy regular and pathological gamblers by applying the Duplication of Purchase Law. Current study uses data collected by the Australian Productivity Commission for eight different types of games. Key behavioral statistics on light regular, heavy regular, and pathological gamblers were computed and compared. The key finding is that pathological gambling, just like regular gambling, follows the Duplication of Purchase Law, which states that the dominant factor of purchase duplication between two brands is their market shares. This means that gambling between any two games at pathological level, like any regular consumer purchases, exhibits "law-like" regularity based on the pathological gamblers' participation rate of each game. Additionally, pathological gamblers tend to gamble more frequently across all games except lotteries and instant as well as make greater cross-purchases compared to heavy regular gamblers. A better understanding of the behavioral traits between regular (particularly heavy regular) and pathological gamblers can be useful to public policy makers and social marketers in order to more accurately identify such gamblers and better manage the negative impacts of gambling.

Hip Hop HEALS: Pilot Study of a Culturally Targeted Calorie Label Intervention to Improve Food Purchases of Children.

We explored the effect of a culturally targeted calorie label intervention on food purchasing behavior of elementary school students. We used a quasi-experimental design with two intervention schools and one control school to assess food purchases of third through fifth graders at standardized school food sales before and after the intervention (immediate and delayed) in schools. The intervention comprised three 1-hour assembly-style hip-hop-themed multimedia classes. A mean total of 225 children participated in two baseline preintervention sales with and without calorie labels; 149 children participated in immediate postintervention food sales, while 133 children participated in the delayed sales. No significant change in purchased calories was observed in response to labels alone before the intervention. However, a mean decline in purchased calories of 20% (p < .01) and unhealthy foods (p < .01) was seen in immediately following the intervention compared to baseline purchases, and this persisted without significant decay after 7 days and 12 days. A 3-hour culturally targeted calorie label intervention may improve food-purchasing behavior of children. © 2015 Society for Public Health Education.

Eggs and Poultry Purchase, Storage, and Preparation Practices of Consumers in Selected Asian Countries

2014-01-01

The objective of this study was to begin characterizing purchase, storage, handling, and preparation of poultry products and eggs by selected consumers in three Asian countries: India, Korea, and Thailand. Approximately 100 consumers in each location were recruited to participate in this study. The consumers were surveyed about eggs and poultry purchase behavior characteristics, such as temperatures and locations, storage behavior, such as storage locations in the refrigerator or freezer, preparation behavior, such as washing eggs and poultry before cooking, and handling behavior, such as using cutting boards during cooking. The results indicated differences in purchase and storage practices of raw eggs. Most Korean consumers purchased refrigerated eggs and stored the eggs in the refrigerator, while Indian and Thai consumers bought eggs that were stored at room temperature, but would refrigerate the eggs at home. Approximately half of the consumers in each country froze raw meat, poultry, or seafood. Food preparation practices showed potential for cross-contamination during cooking, such as using the same cutting board for different kinds of foods or not washing hands with soap and water. The results presented in this pilot study may lead to development of educational messages and raising consumer awareness of food safety practices in Asian countries. PMID:28234307

Local food environments can influence the diet and health of individuals through food availability, proximity to retail stores, pricing, and promotion. This study focused on how small convenience stores, known in New York City as bodegas, influence resident shopping behavior and the food environment. Using a cross-sectional design, 171 bodegas and 2118 shoppers were sampled. Small convenience stores in New York City. Any bodega shopper aged 18+ who purchased food or beverage from a participating store. Data collection consisted of a store assessment, a health and behavior survey given to exiting customers, and a bag check that recorded product information for all customer purchases. Descriptive statistics were generated for bodega store characteristics, shopper demographics, and purchase behavior. Multilevel models were used to assess the influence of product availability, placement, and advertising on consumer purchases of sugar-sweetened beverages (SSBs), water, and fruits and vegetables. Seventy-one percent of participants reported shopping at bodegas five or more times per week, and 35% reported purchasing all or most of their monthly food allotment at bodegas. Model results indicated that lower amounts of available fresh produce were significantly and independently associated with a higher likelihood of SSB purchases. A second, stratified multilevel model showed that the likelihood of purchasing an SSB increased with decreasing varieties of produce when produce was located at the front of the store. No significant effects were found for water placement and beverage advertising. Small convenience stores in New York City are an easily accessible source of foods and beverages. Bodegas may be suitable for interventions designed to improve food choice and diet.

The power of putting a label on it: green labels weigh heavier than contradicting product information for consumers’ purchase decisions and post-purchase behavior

Green products are appealing. Thus, labeling products as environmentally friendly is an effective strategy to increase sales. However, the labels often promise more than the products can actually deliver. In the present research, we examined the expectation that consumers with high ecological motivation have strong preferences for green-labeled products – even when presented product information contradicts the label’s image. This unsettling hypothesis is grounded in the labels’ potential to create a cognitive match between the labeled product and consumers’ motives. For labels indicating environmental friendliness (green product labels), this link should be strongest when consumers’ ecological motivation is high. Findings in a series of three experiments support our assumption, showing that consumers with high ecological motivation had strong preferences (i.e., product evaluations, purchase intentions, and simulated purchase decisions) for green-labeled products as compared to consumers with low ecological motivation (Studies 1–3). Crucially, these preferences were robust, despite contradicting environmental product information (Studies 1 and 2). We extended our findings by additionally examining the impact of product labels and motivation on moral self-regulation processes. This was established by assessing participants’ pro-social behavior after the purchase task: participants with high ecological motivation acted, consistent with their motives, more pro-socially in post-decision occasions. In accordance with moral cleansing effects, pro-social behavior was intensified after purchasing conventional products (Studies 2 and 3). Green labels protected participants with high ecological motivation from moral threats due to the purchase, thus making pro-social behavior less likely. Findings suggest that highly ecologically motivated consumers are most susceptible to green labels, which may override detailed product information. PMID:26441767

Background: In the past decade, the United States has seen declining energy intakes and plateauing obesity levels. Objective: We examined whether these observed trends suggest a longer-term shift in dietary and health behavior that is independent of adverse economic conditions. Design: We used nationally representative cross-sectional surveys on intake and longitudinal household food purchase data along with random-effects models to address this question. Data included individuals in NHANES 2003–2004 to 2009–2010 (children: n = 13,422; adults: n = 10,791) and households from the 2000–2011 Nielsen Homescan Panel (households with children: n = 57,298; households with adults only: n = 108,932). Results: In both data sets, we showed that children decreased their calories the most. Even after we controlled for important socioeconomic factors, caloric purchases fell significantly from 2003 to 2011 (P < 0.001), particularly for households with children. The Great Recession was associated with small increases in caloric purchases, in which a 1–percentage point increase in unemployment in the local market was associated with a 1.6–4.1-kcal · capita−1 · d−1 (P < 0.001) increase in total calories purchased. Results also indicated shifts in caloric purchases were driven more by declines in caloric purchases from beverages than food. Conclusions: US consumers have exhibited changes in intake and purchasing behavior since 2003 that were independent from changing economic conditions linked with the Great Recession or food prices. Public health efforts in the past decade may have contributed to this trend. PMID:24429538

The objective of this case study was to evaluate the acceptability, sales impact, and implementation barriers for the Chicago Park District's 100% Healthier Snack Vending Initiative to strengthen and support future healthful vending efforts. The Chicago Park District is the largest municipal park system in the United States, serving almost 200,000 children annually through after-school and summer programs. Chicago is one of the first US cities to improve park food environments through more healthful snack vending. A community-based participatory evaluation engaged community and academic partners, who shared in all aspects of the research. From spring 2011 to fall 2012, we collected data through observation, surveys, and interviews on staff and patron acceptance of snack vending items, purchasing behaviors, and machine operations at a sample of 10 Chicago parks. A new snack vending contract included nutrition standards for serving sizes, calories, sugar, fat, and sodium for all items. Fifteen months of snack vending sales data were collected from all 98 snack vending machines in park field houses. Staff (100%) and patrons (88%) reacted positively to the initiative. Average monthly per-machine sales increased during 15 months ($84 to $371). Vendor compliance issues included stocking noncompliant items and delayed restocking. The initiative resulted in improved park food environments. Diverse partner engagement, participatory evaluation, and early attention to compliance can be important supports for healthful vending initiatives. Consumer acceptance and increasing revenues can help to counter fears of revenue loss that can pose barriers to adoption.

Designing Interventions that Last: A Classification of Environmental Behaviors in Relation to the Activities, Costs, and Effort Involved for Adoption and Maintenance

PubMed Central

Moore, Harriet E.; Boldero, Jennifer

2017-01-01

Policy makers draw on behavioral research to design interventions that promote the voluntary adoption of environmental behavior in societies. Many environmental behaviors will only be effective if they are maintained over the long-term. In the context of climate change and concerns about future water security, behaviors that involve reducing energy consumption and improving water quality must be continued indefinitely to mitigate global warming and preserve scarce resources. Previous reviews of environmental behavior have focused exclusively on factors related to adoption. This review investigates the factors that influence both adoption and maintenance, and presents a classification of environmental behaviors in terms of the activities, costs, and effort required for both adoption and maintenance. Three categories of behavior are suggested. One-off behaviors involve performing an activity once, such as purchasing an energy efficient washing machine, or signing a petition. Continuous behaviors involve the performance of the same set of behaviors for adoption and for maintenance, such as curbside recycling. Dynamic behaviors involve the performance of different behaviors for adoption and maintenance, such as revegetation. Behaviors can also be classified into four categories related to cost and effort: those that involve little cost and effort for adoption and maintenance, those that involve moderate cost and effort for adoption and maintenance, those that involve a high cost or effort for adoption and less for maintenance, and those that involve less cost or effort for adoption and a higher amount for maintenance. In order to design interventions that last, policy makers should consider the factors that influence the maintenance as well as the adoption of environmental behaviors. PMID:29163265

Unlike other chains, Subway posted calorie information at point of purchase and its patrons more often reported seeing calorie infomation than patrons of other chains (32% vs 4%; P<.001); Subway patrons who saw calorie information purchased 52 fewer calories than did other Subway patrons (P<.01). Fast-food chains should display calorie information prominently at point of purchase, where it can be seen and used to inform purchases. PMID:18556597

Why do consumers respond to eco-labels? The case of Korea.

PubMed

Hwang, Jung-Ah; Park, Youkyoung; Kim, Yeonbae

2016-01-01

Although eco-labels were introduced with the intention of encouraging eco-friendly purchasing behavior by consumers, they have had little effect on consumers' purchasing decisions, and therefore a significant gap exists between eco-label awareness and actual purchasing behavior. The aim of this study was to analyze consumer preference, in terms of public and private values, for two types of Korean eco-label that have been administered by the Korean government since 1992. Analyses were based on a structural equation model, employing the theory of reasoned action. Data were collected by survey. The results indicate that although general consumers are highly aware of the publicly valuable information that eco-labels provide, privately valuable information exerts far greater power over their purchasing intentions. Therefore, a supplementary policy that converts public value to private value could promote the purchase of eco-labeled products.

Epstein, Leonard H; Dearing, Kelly K; Handley, Elizabeth A; Roemmich, James N; Paluch, Rocco A

2006-07-01

To our knowledge, there are no data on parental influences on child purchasing behavior of healthy or unhealthy foods. Mothers and children in ten families were given 5.00 US dollars to purchase portions of preferred fruits/vegetables and high energy-dense snack foods for each of ten trials of price manipulations. For five of the trials the price of the fruit/vegetable increased in price from 0.50 US dollars to 2.50 US dollars (in 0.50 US dollar increments), while the price of the energy-dense snack food remained constant at 1.00 US dollar. For the remaining five trials, the commodity that previously rose in price remained constant at 1.00 US dollars and the other commodity varied from 0.50 US dollars to 2.50 US dollars. Same-price elasticity was shown for both the child and parent purchases, and parent purchases were significantly related to child purchases of both healthy (regression estimate = 0.46, p < 0.001) and unhealthy (regression estimate = 0.12, p = 0.036) foods. Children's purchases of unhealthy snack food items were positively related to family socioeconomic status, and negatively related to child age. These results indicate that parental food choice and purchasing behaviors may play a role in the development of children's purchasing of both healthy and unhealthy foods.

Individual decision making in the non-purchase of long-term care insurance.

Curry, Leslie A; Robison, Julie; Shugrue, Noreen; Keenan, Patricia; Kapp, Marshall B

2009-08-01

Although prior research suggests that economic, behavioral, and psychosocial factors influence decisions not to purchase long-term care insurance, few studies have examined the interplay among these factors in depth and from the consumer's point of view. This study was intended to further illuminate these considerations, generate hypotheses about non-purchasing decisions, and inform the design of policies that are responsive to concerns and preferences of potential purchasers. Qualitative study using 32 in-depth interviews and 6 focus groups, following a grounded theory approach. Five themes characterize decisions not to purchase long-term care insurance: (a) the determination that a policy is "too costly" reflects highly individualized and complex trade-offs not solely economic in nature, (b) non-purchasers are skeptical about the viability and integrity of private insurance companies and seek an unbiased source of information, (c) family dynamics play an important role in insurance decisions, (d) contemplating personal risk for long-term care triggers psychological responses that have implications for decision making, and (e) non-purchasers feel inadequately informed and overwhelmed by the process of deciding whether to purchase long-term care insurance. States are seeking to offset escalating Medicaid long-term care expenditures through a variety of policy mechanisms, including stimulating individual purchase of long-term care insurance. Findings suggest that economic incentives such as lowering premiums will be necessary but not sufficient to attract appropriate candidates. Attention to behavioral and psychosocial factors is essential to designing incentives that are responsive to concerns and preferences of potential purchasers.

Peaches (Prunus persica (L.) Stokes) are grown in several regions throughout the USA, are eaten fresh, and used as ingredients in value-added processed products. An Internet survey was conducted to investigate Mid-Atlantic consumers' fresh and processed peach purchasing behaviors, and whether packaging certain numbers of peaches together, providing information about nutritional content, and other factors would increase purchases. Additionally, laboratory-based sensory testing was used to better understand peel color, texture, sweetness, sourness, and flavor preferences for cultivars commonly grown in the Mid-Atlantic region. Irrespective of fresh peach consumption frequency, certain value-added products were of interest. For some products, interest in purchasing was higher than reported purchasing behavior. Preference for certain fresh peach characteristics, such as peel color, differed between less frequent fresh peach consumers and those who consumed fresh peaches more often. Of the four peach cultivars included in the sensory test, most were liked; however, there were some cultivar differences pertaining to color, texture, sweetness, tartness, and flavor liking. Potential marketing strategies can be developed based on frequency of fresh peach consumption and household demographics. Data can be used to select peaches that best appeal to consumers. © 2015 Society of Chemical Industry. © 2015 Society of Chemical Industry.

Retail food environments have received attention for their influence on dietary behaviors and for their nutrition intervention potential. To improve diet-related behaviors, such as fruit and vegetable (FV) purchasing, it is important to examine its relationship with in-store environmental characteristics. This study used baseline data from the " El Valor de Nuestra Salud " study to examine how in-store environmental characteristics, such as product availability, placement and promotion, were associated with FV purchasing among Hispanic customers in San Diego County. Mixed linear regression models indicated that greater availability of fresh FVs was associated with a $0.36 increase in FV purchasing ( p = 0.01). Placement variables, specifically each additional square foot of display space dedicated to FVs ( p = 0.01) and each additional fresh FV display ( p = 0.01), were associated with a $0.02 increase and $0.29 decrease, respectively, in FV purchasing. Introducing FV promotions in the final model was not related to FV purchasing. Exploratory analyses indicated that men reported spending $3.69 fewer dollars on FVs compared to women, controlling for covariates ( p = 0.02). These results can help inform interventions targeting in-store environmental characteristics to encourage FV purchasing among Hispanics.

Among high-risk youth, those who may be at increased risk for adverse alcohol and other drug (AOD) use outcomes may benefit from targeted prevention efforts; how youth acquire AOD may provide an objective means of identifying youth at elevated risk. We assessed how youth acquired alcohol and marijuana (purchasing vs. other means), demographics, AOD behaviors/consequences, and environment among adolescents referred to a diversion program called Teen Court (N = 180) at two time points (prior to the program and 180 days from baseline). Participants were predominantly White and Hispanic/Latino(a). In cross-sectional analyses among alcohol and marijuana users, purchasing marijuana was associated with more frequent marijuana use and consequences, time spent around teens who use marijuana, higher likelihood of substance use disorders, and lower resistance self-efficacy compared to non-purchasers. Teens who purchased both alcohol and marijuana experienced similar outcomes to those who purchased only marijuana, and also reported more frequent and higher quantity of drinking, greater alcohol-related consequences, time spent around teens who use other drugs, and prescription drug misuse. Longitudinally, purchasing alcohol and marijuana at baseline was associated with more frequent and higher quantity of drinking compared to non-purchasers at follow-up. Marijuana only purchasers had a greater likelihood of substance use disorders at follow-up compared to non-purchasers. In an era where drinking is commonplace and attitudes towards marijuana use are becoming more tolerant, it is essential to evaluate how accessibility to AOD and subsequent purchasing behaviors affect youth consumption and intervene accordingly to prevent future consequences.

Heroin purchasing is income and price sensitive.

Semi-structured interviews were used to assess behavioral economic drug demand in heroin dependent research volunteers. Findings on drug price, competing purchases, and past 30-day income and consumption, established in a previous study, are replicated. We extended these findings by having participants indicate whether hypothetical environmental changes would alter heroin purchasing. Participants (n = 109) reported they would significantly (p < .005) decrease heroin daily purchasing amounts (DPA) from past 30-day levels (M = $60/day) if: (a) they encountered a 33% decrease in income (DPA = $34), (b) family/friends no longer paid their living expenses (DPA = $32), or (c) they faced four-fold greater likelihood of police arrest at their purchasing location (DPA = $42). Participants in higher income quartiles (who purchase more heroin) show greater DPA reductions (but would still buy more heroin) than those in lower income quartiles. For participants receiving government aid (n = 31), heroin purchasing would decrease if those subsidies were eliminated (DPA = $28). Compared to participants whose urine tested negative for cocaine (n = 31), cocaine-positive subjects (n = 32) reported more efficient heroin purchasing, that is, they live closer to their primary dealer; are more likely to have heroin delivered or walk to obtain it (and less likely to ride the bus), thus reducing purchasing time (52 vs. 31 min, respectively); and purchase more heroin per episode. These simulation results have treatment and policy implications: Daily heroin users' purchasing repertoire is very cost-effective, more so for those also using cocaine, and only potent environmental changes (income reductions or increased legal sanctions) may impact this behavior.

To understand the impact of healthy checkouts in Bronx, New York City supermarkets. Consumer purchasing behavior was observed for 2 weeks in 2015. Three supermarkets in the South Bronx. A total of 2,131 adult shoppers (aged ≥18 years) who paid for their groceries at 1 of the selected study checkout lines. Two checkout lines were selected per store; 1 was converted to a healthy checkout and the other remained as it was (standard checkout). Data collectors observed consumer behavior at each line and recorded items purchased from checkout areas. Percentage of customers who purchase items from the checkout area; quantity and price of healthy and unhealthy items purchased from the healthy and standard checkout lines. Measures were analyzed by study condition using chi-square and t tests; significance was determined at α = .05. Only 4.0% of customers bought anything from the checkout area. A higher proportion of customers using the healthy vs standard checkout line bought healthy items (56.5% vs 20.5%; P < .001). When healthier products were available, the proportion of healthy purchases increased. Findings contribute to limited research on effectiveness of healthy checkouts in supermarkets. Similar interventions should expect an increase in healthy purchases from the checkout area, but limited overall impact. Copyright © 2017 Society for Nutrition Education and Behavior.

Effect of Machining Parameters on Oxidation Behavior of Mild Steel

NASA Astrophysics Data System (ADS)

Majumdar, P.; Shekhar, S.; Mondal, K.

2015-01-01

This study aims to find out a correlation between machining parameters, resultant microstructure, and isothermal oxidation behavior of lathe-machined mild steel in the temperature range of 660-710 °C. The tool rake angles "α" used were +20°, 0°, and -20°, and cutting speeds used were 41, 232, and 541 mm/s. Under isothermal conditions, non-machined and machined mild steel samples follow parabolic oxidation kinetics with activation energy of 181 and ~400 kJ/mol, respectively. Exaggerated grain growth of the machined surface was observed, whereas, the center part of the machined sample showed minimal grain growth during oxidation at higher temperatures. Grain growth on the surface was attributed to the reduction of strain energy at high temperature oxidation, which was accumulated on the sub-region of the machined surface during machining. It was also observed that characteristic surface oxide controlled the oxidation behavior of the machined samples. This study clearly demonstrates the effect of equivalent strain, roughness, and grain size due to machining, and subsequent grain growth on the oxidation behavior of the mild steel.

Competitive foods and beverages available for purchase in secondary schools--selected sites, United States, 2006.

PubMed

2008-08-29

Schools are in a unique position to help improve youth dietary behaviors and prevent and reduce obesity. In most schools, foods and beverages are made available to students through the U.S. Department of Agriculture (USDA) school meal programs and the sale of competitive foods, which are any foods and beverages sold at a school separately from the USDA school meal programs. Foods and beverages sold through the USDA school meal programs must meet federal nutrition requirements. Competitive foods are not subject to any federal nutrition standards unless they are sold inside the food service area during mealtimes. A 2007 Institute of Medicine (IOM) report concluded that schools should limit the availability of less nutritious competitive foods or include more nutritious foods and beverages if they make competitive foods available. To identify the types of competitive foods and beverages available for purchase from vending machines or at school stores, canteens, or snack bars, CDC analyzed data from the 2006 School Health Profiles for public secondary schools in 36 states and 12 large urban school districts. CDC also compared 2004 and 2006 data among 24 states and nine large urban school districts. This report summarizes the results of these analyses, which indicated that, from 2004 to 2006, the median percentage of secondary schools across states allowing students to purchase chocolate candy and salty snacks that are not low in fat decreased; however, in 2006, secondary schools still offered less nutritious foods and beverages that compete with school meals. School and public health officials should work together with families to provide foods and beverages at school that follow the IOM recommendations.

The purpose of this study was to identify and examine the dimensions of problem gambling behaviors associated with purchasing sports lottery in China. This was accomplished through the development and validation of the Scale of Assessing Problem Gambling (SAPG). The SAPG was initially developed through a comprehensive qualitative research process. Research participants (N = 4,982) were Chinese residents who had purchased sports lottery tickets, who responded to a survey packet, representing a response rate of 91.4%. Data were split into two halves, one for conducting an EFA and the other for a CFA. A five-factor model with 19 items (Social Consequence, Financial Consequence, Harmful Behavior, Compulsive Disorder, and Depression Sign) showed good measurement properties to assess problem gambling of sports lottery consumers in China, including good fit to the data (RMSEA = 0.050, TLI = 0.978, and CFI = 0.922), convergent and discriminate validity, and reliability. Regression analyses revealed that except for Depression Sign, the SAPG factors were significantly (P < 0.05) predictive of purchase behaviors of sports lottery. This study represents an initial effort to understand the dimensions of problem gambling associated with Chinese sports lottery. The developed scale may be adopted by researchers and practitioners to examine problem gambling behaviors and develop effective prevention and intervention procedures based on tangible evidence.

A field application of behavior modification studied the relative effectiveness of different prompting procedures for increasing the probability that customers entering a grocery store would select their soft drinks in returnable rather than nonreturnable containers. Six different 2-hr experimental conditions during which bottle purchases were recorded were (1) No Prompt (i.e., control), (2) one student gave incoming customers a handbill urging the purchase of soft drinks in returnable bottles, (3) distribution of the handbill by one student and public charting of each customer's bottle purchases by another student, (4) handbill distribution and charting by a five-member group, (5) handbills distributed and purchases charted by three females. The variant prompting techniques were equally effective, and in general increased the percentage of returnable-bottle customers by an average of 25%. PMID:16795418

This paper examines how socio-economic status (SES) modifies how smokers adjust to changes in the price of tobacco products through utilization of multiple price minimizing techniques. Data come from the International Tobacco Control Policy Evaluation (ITC) Four Country Survey, nationally representative samples of adult smokers and includes respondents from Canada, the United States, the United Kingdom and Australia. Cross-sectional analyses were completed among 8,243 respondents (7,038 current smokers) from the survey wave conducted between October 2006 and February 2007. Analyses examined predictors of purchasing from low/untaxed sources, using discount cigarettes or roll-your-own (RYO) tobacco, purchasing cigarettes in cartons, and engaging in high levels of price and tax avoidance at last purchase. All analyses tested for interactions with SES and were weighted to account for changing and under-represented demographics. Relatively high levels of price and tax avoidance behaviors were present; 8% reported buying from low or untaxed source; 36% used discount or generic brands, 13.5% used RYO tobacco, 29% reported purchasing cartons, and 63% reported using at least one of these high price avoidance behaviors. Respondents categorized as having low SES were approximately 26% less likely to report using low or untaxed sources and 43% less likely to purchase tobacco by the carton. However, respondents with low SES were 85% more likely to report using discount brands/RYO compared to participants with higher SES. Overall, lower SES smokers were 25% more likely to engage in at least one or more tax avoidance behaviors compared to their higher SES counterparts. Price and tax avoidance behaviors are relatively common among smokers of all SES strata, but strategies differed with higher SES groups more likely to report traveling to a low-tax location to avoid paying higher prices, purchase duty free tobacco, and purchase by cartons instead of packs all of which were less commonly reported by low SES smokers. Because of the strategies lower SES respondents are more likely to use, reducing price differentials between discount and premium brands may have a greater impact on them, potentially increasing the likelihood of quitting.

People with mental illness often experience unique barriers to healthy eating and physical activity. For these clients, interventions should focus on changes in the immediate environment to change behaviors. The purpose of this project was to implement and evaluate policy changes that would limit calorie intake and increase calorie expenditure of clients receiving mental health services. This intervention was implemented in a rural mental health system in the southeastern United States. Clients live in small group homes, where they are served breakfast, dinner, and a snack, and attend outpatient day treatment programs, where they are served lunch and can purchase snacks from vending machines. This intervention included institutional policy changes that altered menus and vending machine options and implemented group walking programs. Primary outcome measures were changes in clients' weight at 3 and 6 months after policy implementation. At the 3-month follow-up, the median weight loss for overweight/obese clients (n = 45) was 1.4 kg. The 33 overweight/obese clients who were still in the group homes at the 6-month follow-up either maintained or continued to lose weight. Institutional policy changes aimed at improving dietary intake and physical activity levels among clients receiving mental health services can promote weight loss in overweight clients.

In 2010, the United States (US) enacted a restaurant menu labeling law. The law also applied to vending machine companies selling food. Research suggested that providing nutrition information on menus in restaurants might reduce the number of calories purchased. We tested the effect of providing nutrition information and 'healthy' designations to consumers where vending machines were located in college residence halls. We conducted our study at one university in Southeast US (October-November 2012). We randomly assigned 18 vending machines locations (residence halls) to an intervention or control group. For the intervention we posted nutrition information, interpretive signage, and sent a promotional email to residents of the hall. For the control group we did nothing. We tracked sales over 4 weeks before and 4 weeks after we introduced the intervention. Our intervention did not change what the residents bought. We recommend additional research about providing nutrition information where vending machines are located, including testing formats used to present information.

Business case studies are being looked at to support procurement of new machines and capital equipment in the SM-39 and TA-03-0102 machine shops. The first effort conducted economic analysis of replacing the Mazak 30Y Mill-Turn Machine located in SM-39. To determine the value of switching machinery, a baseline scenario was compared with a future scenario where new machinery was purchased and installed. The conditions under the two scenarios were defined via interviews with subject matter experts in terms of one-time and periodic costs. The results of the analysis were compiled in a life-cycle cost/benefit table. The costs of procuring, installing,more » and maintaining a new machine were balanced against the costs avoided by replacing older machinery. Productivity savings were included as a measure to show the costs avoided by being able to produce parts at a quicker and more efficient pace.« less

Do green products make us better people?

PubMed

Mazar, Nina; Zhong, Chen-Bo

2010-04-01

Consumer choices reflect not only price and quality preferences but also social and moral values, as witnessed in the remarkable growth of the global market for organic and environmentally friendly products. Building on recent research on behavioral priming and moral regulation, we found that mere exposure to green products and the purchase of such products lead to markedly different behavioral consequences. In line with the halo associated with green consumerism, results showed that people act more altruistically after mere exposure to green products than after mere exposure to conventional products. However, people act less altruistically and are more likely to cheat and steal after purchasing green products than after purchasing conventional products. Together, our studies show that consumption is connected to social and ethical behaviors more broadly across domains than previously thought.

To identify healthy food (HF) purchase habits and intake of fruits and vegetables (FV) in parents responsible for grocery shopping for their families. Survey with mothers and fathers (n = 216) of children aged 7-10 years in Brazil. Grocery purchases occurred mostly at supermarkets. Purchase of HF was considered to be frequent by 80% of parents, who cited FV as main examples of HF. The more frequent the reported purchase was of HF, the higher was the prevalence of regular consumption of FV (P = .002). Only 34% of respondents reported weekly intakes that could be classified as regular. Perceived frequent shopping for healthy foods was positively associated with regular consumption of FV but a gap between perception and behavior was identified. Nutrition education strategies need to go beyond a merely informative role and take consumers' opinions and points of view into consideration to become truly effective.

Proper age verification can prevent minors from accessing tobacco products. For this reason, electronic locking devices based on a proof-of age system utilising cards were installed in almost every tobacco vending machine across Japan and Germany to restrict sales to minors. We aimed to clarify the associations between amount smoked by high school students and the usage of age verification cards by conducting a nationwide cross-sectional survey of students in Japan. This survey was conducted in 2008. We asked high school students, aged 13-18 years, in Japan about their smoking behaviour, where they purchase cigarettes, if or if not they have used age verification cards, and if yes, how they obtained this card. As the amount smoked increased, the prevalence of purchasing cigarettes from vending machines also rose for both males and females. The percentage of those with experience of using an age verification card was also higher among those who smoked more. Somebody outside of family was the top source of obtaining cards. Surprisingly, around 5% of males and females belonging to the group with highest smoking levels applied for cards themselves. Age verification cards cannot fully prevent minors from accessing tobacco products. These findings suggest that a total ban of tobacco vending machines, not an age verification system, is needed to prevent sales to minors.

To improve diet-related behaviors, such as fruit and vegetable (FV) purchasing, it is important to examine its relationship with in-store environmental characteristics. This study used baseline data from the “El Valor de Nuestra Salud” study to examine how in-store environmental characteristics, such as product availability, placement and promotion, were associated with FV purchasing among Hispanic customers in San Diego County. Mixed linear regression models indicated that greater availability of fresh FVs was associated with a $0.36 increase in FV purchasing (p = 0.01). Placement variables, specifically each additional square foot of display space dedicated to FVs (p = 0.01) and each additional fresh FV display (p = 0.01), were associated with a $0.02 increase and $0.29 decrease, respectively, in FV purchasing. Introducing FV promotions in the final model was not related to FV purchasing. Exploratory analyses indicated that men reported spending $3.69 fewer dollars on FVs compared to women, controlling for covariates (p = 0.02). These results can help inform interventions targeting in-store environmental characteristics to encourage FV purchasing among Hispanics. PMID:29077075

This study examines purchases at fruit and vegetable carts and evaluates the potential benefits of expanding the availability of electronic benefit transfer machines at Green Carts. Customers at 4 Green Carts in the Bronx, New York, were surveyed in 3 waves from June 2013 through July 2014. Customers who used Supplemental Nutrition Assistance Program benefits spent on average $3.86 more than customers who paid with cash. This finding suggests that there may be benefits to increasing the availability of electronic benefit transfer machines at Green Carts.

Tobacco control environment in the United States and individual consumer characteristics in relation to continued smoking: Differential responses among menthol smokers?

PubMed Central

Lewis, Michael; Wang, Yanwen; Berg, Carla J.

Objective We used a consumer panel augmented with state-specific measures of tobacco control activities to examine main effects and interactions among consumer behaviors, particularly menthol cigarette smoking, and tobacco control environment on cessation over a six-year period. Methods We used the Nielson Homescan Panel, which tracks consumer purchasing behaviors, and tobacco control information matched to panelist zip code. We focused on 1,582 households purchasing ≥20 packs from 2004–2009. Our analysis included demographics; purchasing behavior including menthol versus nonmenthol use (≥80% of cigarettes purchased being menthol), quality preferences (average price/pack), purchase recency, and nicotine intake (nicotine levels of cigarettes purchased); and tobacco control metrics (taxation, anti-tobacco advertising, smoke-free policies). Results Menthol smoking (Hazards Ratio [HR]=0.79, 95% Confidence Interval [CI] 0.64, 0.99), being African American (HR=0.67, CI 0.46, 0.98), being male (HR=0.46; CI 0.28, 0.74), higher quality premium preferences (HR=0.80, CI0.77, 0.91), lower recency (HR=1.04, CI 1.02, 1.05), and higher nicotine intake rates (HR=0.99, CI 0.99, 0.99) were related to continued smoking. No significant interactions were found. Conclusion While there were no interactions between menthol use and effects of tobacco control activities, we did find additional support for the decreased cessation rates among menthol cigarette smokers, particularly in the African American population.

Tomaszewski, K; Motwani, J

1995-01-01

A large sum of money is spent annually by salespeople on gifts and favors for purchasing executives. The provision of gifts and favors to buyers remains a common practice despite the fact that it often leads to ethical conflicts for purchasing executives, sales managers, and salespeople. This paper investigates the perceptions of 51 purchasing executives of midwest hospitals regarding their behavior towards certain buying practices, the favors offered by vendors, favors actually accepted, as well as purchasers' discomfort and repayment levels regarding indebtedness. Based on the data analysis, this paper provides conclusions and directions for future research.

To develop healthier vending guidelines and assess their effect on the nutrient content and sales of snack products sold through hospital vending machines, and on staff satisfaction. Nutrition guidelines for healthier vending machine products were developed and implemented in 14 snack vending machines at two hospital sites in Auckland, New Zealand. The guidelines comprised threshold criteria for energy, saturated fat, sugar, and sodium content of vended foods. Sales data were collected prior to introduction of the guidelines (March-May 2007), and again post-introduction (March-May 2008). A food composition database was used to assess impact of the intervention on nutrient content of purchases. A staff survey was also conducted pre- and post-intervention to assess acceptability. Pre-intervention, 16% of staff used vending machines once a week or more, with little change post-intervention (15%). The guidelines resulted in a substantial reduction in the amount of energy (-24%), total fat (-32%), saturated fat (-41%), and total sugars (-30%) per 100 g product sold. Sales volumes were not affected, and the proportion of staff satisfied with vending machine products increased. Implementation of nutrition guidelines in hospital vending machines led to substantial improvements in nutrient content of vending products sold. Wider implementation of these guidelines is recommended.

The Inspection Shop at Lawrence Livermore Lab recently purchased a Sheffield Apollo RS50 Direct Computer Control Coordinate Measuring Machine. The performance of the machine was specified to conform to B89 standard which relies heavily upon using the measuring machine in its intended manner to verify its accuracy (rather than parametric tests). Although it would be possible to use the interactive measurement system to perform these tasks, a more thorough and efficient job can be done by creating Function Library programs for certain tasks which integrate Hewlett-Packard Basic 5.0 language and calls to proprietary analysis and machine control routines. This combinationmore » provides efficient use of the measuring machine with a minimum of keyboard input plus an analysis of the data with respect to the B89 Standard rather than a CMM analysis which would require subsequent interpretation. This paper discusses some characteristics of the Sheffield machine control and analysis software and my use of H-P Basic language to create automated measurement programs to support the B89 performance evaluation of the CMM. 1 ref.« less

From heavy-tailed to exponential distribution of interevent time in cellphone top-up behavior

NASA Astrophysics Data System (ADS)

Wang, Peng; Ma, Qiang

2017-05-01

Cellphone top-up is a kind of activities, to a great extent, driven by individual consumption rather than personal interest and this behavior should be stable in common sense. However, our researches find there are heavy-tails both in interevent time distribution and purchase frequency distribution at the global level. Moreover, we find both memories of interevent time and unit price series are negative, which is different from previous bursty activities. We divide individuals into five groups according to the purchase frequency and the average unit price respectively. Then, the group analysis shows some significant heterogeneity in this behavior. On one hand, we obtain only the individuals with high purchase frequency have the heavy-tailed nature in interevent time distribution. On the contrary, the negative memory is only caused by low purchase-frequency individuals without burstiness. On the other hand, the individuals with different preferential price also have different power-law exponents at the group level and there is no data collapse after rescaling between these distributions. Our findings produce the evidence for the significant heterogeneity of human activity in many aspects.

Considerable work on consumers' food safety habits has highlighted issues associated with home food preparation. However, consumer handling of foods, such as poultry, during shopping and storage has not been noted. The objective of this study was to determine consumer behaviors during purchasing and initial storage of raw poultry to determine potential cross-contamination issues. A shop-along observational study was conducted to determine actual shopping, transportation, and storage behavior of consumers who purchase raw poultry products. Neither hand sanitizer nor wipes were observed in 71% of grocery store meat sections of stores visited. Plastic bags could be found in the meat section 85% of the time, but only 25% of shoppers used the bag for their raw poultry purchases. During checkout, the poultry was bagged separately from other products 71% of the time. A majority of shoppers stored raw poultry in the original package without an additional container or overwrap. Overall, there needs to be an increase in food safety education on the handling of poultry during purchasing, transportation, and storage.

The objective of this study was to investigate the prevalence and factors associated with purchasing Chinese herbal medicine (CHM) without a physician's prescription among adults. Using data from the 2005 National Health Interview Survey and National Health Insurance, we identified 16,756 individuals aged 20 years and older. Socio-demographic factors, lifestyle, medical services utilization and health behaviors were compared between people with and without a history of purchasing CHM by calculating adjusted odds ratios (ORs) and 95% confidence intervals (CIs) in a multiple logistic regression analysis. The one-month prevalence of purchasing CHM without a physician' prescription was 5.2% in Taiwan. People more likely to purchase CHM included people aged ≥70 years (OR 2.84, 95% CI 2.03-3.99), women (OR 1.28, 95% CI 1.11-1.48), non-indigenous people (OR 2.61, 95% CI 1.29-5.30), and people with an illness not receiving medical care (OR 2.69, 95% CI 2.19-3.31). The prevalence of purchasing CHM without a physician's prescription is high in Taiwan and is correlated with factors such as socio-demographics, disease history, and behaviors surrounding the utilization of medical care.

Computerized point-of-sale (POS) machine software that allows parents to place restrictions on their child's school meal accounts is available. Parents could restrict specific foods (eg, chips), identify specific days the child can purchase extra foods, or set monetary limits. This descriptive study examines the use of parental restrictions on student cafeteria POS accounts in a convenience sample of 2 school districts. POS alerts, with student gender, grade, ethnicity, and students' free or reduced-price meal eligibility, were obtained from 2 school food service departments for the 2007-2008 school year. The alerts were coded into 5 categories: financial, medical, restrictions, snacks OK, and extras OK. The distribution of alerts by district, students, and demographics was then tabulated. District A (4839 students) had more students with alerts (n = 789, 16%) than District B (8510 students; n = 217, 2.6%), and 94 District A students had a second alert. District A parents had to provide written permission for their child to purchase snacks (n = 654, 13.5%) and extra meal items (n = 113, 2.3%). Most alerts were for full-pay students in both districts (74% and 66%) and varied by demographics of the students. Few parents actually used this system to limit student purchases of foods outside the school meal. Future studies should investigate the influence of these restrictions on student food choices. © 2011, American School Health Association.

Observance of the hunger-obesity paradox in urban Minnesota has ignited interest in the quality of low-income households' food purchases. This cross-sectional study investigated low-income, urban Minnesotan women's past-month food purchases and their associations with race, homelessness, and aspects of the food system, including food shelf (ie, food pantry) and food store usage, factors believed to influence food choice and grocery shopping behavior. The survey included demographics, the US Department of Agriculture's 18-item Household Food Security Survey Module, and grocery shopping questions related to food purchases and food stores visited in the past month. Participants were a convenience sample of 448 low-income, urban Minnesotan women, and data were collected from February through May 2008. The sample was 44% African American, 35% American Indian, 10% white, and 11% other/mixed race; 37% were homeless. Rates of "less healthy" food group purchases were higher compared to "healthy" food group purchases. Significant racial differences were found with respect to purchasing healthy protein food groups (P<0.05 to P<0.01) but not fruits, vegetables, or whole grains. Homelessness reduced the odds of purchasing most food groups, regardless of nutrient density (P<0.05 to P<0.001). Food shelf and food store usage mainly increased the odds of purchasing "less healthy" food groups (P<0.05 to P<0.01). These findings may help registered dietitians strategize with low-income, urban women how to make best use of food resources within their local food system.

Explaining Counterfeit Alcohol Purchases in Russia.

PubMed

Kotelnikova, Zoya

2017-04-01

Alcohol is a common target of counterfeiting in Russia. Counterfeit alcohol is defined here as the manufacture, distribution, unauthorized placement (forgery) of protected commodity trademarks, and infringement of the exclusive rights of the registered trademark holders of alcoholic beverages. It is often argued that the expansion of the counterfeit product market is due to the steady demand of economically disadvantaged people for low-priced goods. The situation becomes more complicated once deceptive and nondeceptive forms of counterfeiting are taken into account. This study aimed to identify markers of risky behavior associated with the purchase of counterfeit alcohol in Russia. The analysis relied on consumer self-reports of alcohol use and purchase collected nationwide by the Russia Longitudinal Monitoring Survey (RLMS-HSE) in 2012 to 2014. I used a generalized linear mixed-model logistic regression to identify predictors of risky behavior by consumers who purchased counterfeit alcohol, either knowingly or unknowingly, during the 30 days preceding the survey. Purchases of counterfeit alcohol declined slightly from 2012 to 2014, mainly due to a decrease in consumers mistakenly purchasing counterfeit products. Predictors of counterfeit alcohol purchases differed between consumers who knowingly and unknowingly purchased counterfeit products. Nondeceptive purchase of counterfeit alcohol was related primarily to an indifference to alcohol brands. Consumers with social networks that include drinkers of nonbeverage alcohol and producers of homemade alcohol were highly likely to consume counterfeit alcohol deliberately. Problem drinking was significantly associated with a higher risk of both deceptive and nondeceptive purchases of counterfeit alcohol. Poverty largely contributed to nondeceptive counterfeiting. The literature has overestimated the impact of low prices on counterfeit alcohol consumption. Problem drinking and membership in social networks of consumers of surrogate alcohol (i.e., nonbeverage) are more influential in explaining why people purchase counterfeit alcohol. Further research on these 2 factors is needed to more fully understand the purchase and consumption of counterfeit alcoholic beverages. Copyright © 2017 by the Research Society on Alcoholism.

Healthy vending machine policies are viewed as a promising strategy for combating the growing obesity epidemic in the United States. Few studies have evaluated the short- and intermediate-term outcomes of healthy vending policies, especially for interventions that require 100% healthy products to be stocked. To evaluate the potential impact of a 100% healthy vending machine nutrition policy. The vendor's quarterly revenue, product sales records, and nutritional information data from 359 unique vending machines were used to conduct a baseline and follow-up policy analysis. County of Los Angeles facilities, 2013-2015. Vending machines in facilities located across Los Angeles County. A healthy vending machine policy executed in 2013 that required 100% of all products sold in contracted machines meet specified nutrition standards. Policy adherence; average number of calories, sugar, and sodium in food products sold; revenue change. Policy adherence increased for snacks and beverages sold by the vending machines by 89% and 98%, respectively. Average snack and beverage revenues decreased by 37% and 34%, respectively, during the sampled period. Although a 100% healthy vending policy represents a promising strategy for encouraging purchases of healthier foods, steps should be taken to counteract potential revenue changes when planning its implementation.

Using Eye Tracking to Explore Consumers' Visual Behavior According to Their Shopping Motivation in Mobile Environments.

Hwang, Yoon Min; Lee, Kun Chang

2017-07-01

Despite a strong shift to mobile shopping trends, many in-depth questions about mobile shoppers' visual behaviors in mobile shopping environments remain unaddressed. This study aims to answer two challenging research questions (RQs): (a) how much does shopping motivation like goal orientation and recreation influence mobile shoppers' visual behavior toward displays of shopping information on a mobile shopping screen and (b) how much of mobile shoppers' visual behavior influences their purchase intention for the products displayed on a mobile shopping screen? An eye-tracking approach is adopted to answer the RQs empirically. The experimental results showed that goal-oriented shoppers paid closer attention to products' information areas to meet their shopping goals. Their purchase intention was positively influenced by their visual attention to the two areas of interest such as product information and consumer opinions. In contrast, recreational shoppers tended to visually fixate on the promotion area, which positively influences their purchase intention. The results contribute to understanding mobile shoppers' visual behaviors and shopping intentions from the perspective of mindset theory.

To examine how food store environments can promote healthful eating, including (1) preferences for a variety of behavioral economics strategies to promote healthful food purchases, and (2) the cross-sectional association between the primary food store where participants reported shopping, dietary behaviors, and body mass index. Intercept survey participants (n = 342) from 2 midsized eastern North Carolina communities completed questionnaires regarding preferred behavioral economics strategies, the primary food store at which they shopped, and consumption of fruits, vegetables, and sugary beverages. Frequently selected behavioral economic strategies included: (1) a token and reward system for fruit and vegetable purchases; and (2) price discounts on healthful foods and beverages. There was a significant association between the primary food store and consumption of fruits and vegetables (P = .005) and sugary beverages (P = .02). Future studies should examine associations between elements of the in-store food environment, purchases, and consumption. Copyright © 2016 Society for Nutrition Education and Behavior.

Concern about the welfare of production animals is growing among various stakeholders, including the general public. Citizens can influence the market for premium welfare products by expressing public concerns, and consumers-the actors who actually purchase products-can do so through their purchasing behavior. However, current market shares for premium welfare products are small in Europe. To better align purchase behavior with public and individuals' concerns, insight is needed into determinants that influence the intention to purchase premium welfare products. A cross-sectional online survey of 787 Flemish milk consumers was conducted to investigate attitudes toward and intention to purchase animal-friendly milk. More than half of the sample (52.5%) expressed the intention to purchase animal-friendly milk. Linear regression modeling indicated that intention was positively influenced by (1) higher perceived product benefits from animal-friendly milk (milk with more health benefits and higher quality); (2) higher personal importance of extrinsic product attributes such as local production and country of origin; (3) higher personal importance of animal welfare; (4) a more natural living oriented attitude toward cows; and (5) a more positive general attitude toward milk. Intention was negatively influenced by (1) a stronger business-oriented attitude toward cows; and (2) by a higher personal importance attached to price. These insights in key components of purchase intention can assist producers, the dairy industry, and retailers to position and market animal-friendly milk.

Monthly fuel purchase logs from the Residential Energy Consumption Survey's Household Transportation Panel (TP) were analyzed to determine the relationship between various household characteristics and purchase frequency, tank inventories, vehicle-miles traveled, and fuel expenditures. Multiple classification analysis (MCA) was used to relate observed differences in dependent variables to such index-type household characteristics as income and residence location, and sex, race and age of household head. Because it isolates the net effect of each parameter, after accounting for the effects of all other parameters, MCA is particularly appropriate for this type of analysis. Results reveal clear differences in travel and fuelmore » purchase behavior for four distinct groups of vehicle-owning households. Black households tend to own far fewer vehicles with lower fuel economy, to use them more intensively, to purchase fuel more frequently, and to maintain lower fuel inventories than white households. Similarly, poor households own fewer vehicles with lower fuel economy, but they drive them less intensively, purchase fuel more frequently, and maintain lower fuel inventories than nonpoor households. Elderly households also own fewer vehicles with lower fuel economy. But since they drive them much less intensively, their fuel purchases are much less frequent and their fuel inventories are higher than nonelderly households. Female-headed households also own fewer vehicles but with somewhat higher fuel economy. They drive them less intensively, maintain higher fuel inventories, and purchase fuel less frequently than male-headed households. 13 refs., 8 tabs.« less

The authors used a revised planned behavior model in the consumer domain. The revised model incorporated separate measures of descriptive and injunctive/ prescriptive norms, self-identity, and past behavior in an effort to improve the predictive power of the theory of planned behavior (TPB; I. Ajzen, 1985) in relation to a self-reported consumer behavior: purchasing one's preferred soft drink. At Time 1, respondents (N = 112) completed self-report measures of (a) attitudes, (b) perceived behavioral control, (c) descriptive and injunctive/prescriptive norms, (d) self-identity, (e) past behavior, and (f) intentions. The authors assessed self-reported behavior 1 week later (Time 2). Attitudes, injunctive/prescriptive norms, descriptive norms, past behavior, and self-identity were all positively related to purchase intentions, and intentions were predictive of self-reported behavior at Time 2. These findings highlight the utility of the TPB in the consumer domain.

Rost, Kathryn M; Marshall, Donna; Xu, Stanley

Employers can purchase high quality depression products that provide the type, intensity and duration of depression care management shown to improve work outcomes sufficiently for many employers to achieve a return on investment. The purpose of this randomized controlled trial was to test an intervention to encourage employers to purchase a high quality depression product for their workforce. Twenty nine organizations recruited senior health benefit professional members representing public or private employers who had not yet purchased a depression product for all 100+ workers in their company. The research team used randomization blocked by company size to assign eligible employers to: (1) a presentation encouraging employers to purchase a high quality depression product accompanied by a scientifically-derived return on investment estimate, or (2) a presentation encouraging employers to work with their most subscribed health plan to improve depression treatment quality indicators. Two hundred ninety three employers (82.3% of 356) completed baseline data immediately before learning that 140 employers had been randomized to the evidence-based (EB) depression product presentation and 153 had been randomized to the usual care (UC) depression treatment quality indicator presentation. Analysis of 250 (85.3% of 293) employers who completed web-based interviews at 12 and/or 24 months was conducted to determine presentation impact on depression product appraisal and purchasing behavior. The intervention had no impact on depression product appraisal in 232 subjects (F = 2.36, p = .07) or depression product purchasing (chisquare = 1.82, p = .44) in 250 subjects. Depression product appraisal increased in companies with greater health benefit generosity whose benefit professionals were male. Depression product purchasing behavior increased in small companies compared to large companies, companies who knew a vendor that sold depression products at baseline, companies with greater health benefit risk taking, and companies with less politicalization of health care benefit decision making. Policy makers need to build innovative bridges to the employer community to convince them to purchase evidence-based benefits, even when benefits offer potential financial savings. NCT01013220.

Little is known about adolescents' food purchasing behaviors in rural areas. This study examined whether purchasing food at stores/restaurants around schools was related to adolescents' participation in school breakfast programs and overall diet in rural Minnesota. Breakfast-skippers enrolled in a group-randomized intervention in 2014 to 2015 (N = 404 from 8 schools) completed 24-hour dietary recalls and pre/post surveys assessing food establishment purchase frequency. Healthy Eating Index Scores (HEI-2010) were calculated for each student. Student-level school breakfast participation (SBP) was obtained from school food service records. Mixed-effects regression models estimated: (1) whether SBP was associated with store/restaurant use at baseline, (2) whether an increase in SBP was associated with a decrease in store/restaurant use, and (3) whether stores/restaurant use was associated with HEI-2010 scores at baseline. Students with increased SBP were more likely to decrease fast-food restaurant purchases on the way home from school (OR 1.017, 95% CI 1.005, 1.029), but were less likely to decrease purchases at food stores for breakfast (OR 0.979, 95% CI 0.959, 0.999). Food establishment use was associated with lower HEI-2010 dairy component scores (p = .017). Increasing participation in school breakfast may result in modest changes in purchases at food establishments. © 2017, American School Health Association.

2017-12-12

To encourage the consumption of more fresh fruits and vegetables, the 2014 United Sates Farm Bill allocated funds to the Double Up Food Bucks Program. This program provided Supplemental Nutrition Assistance Program beneficiaries who spent $10 on fresh fruits and vegetables, in one transaction, with a $10 gift card exclusively for Michigan grown fresh fruits and vegetables. This study analyzes how fruit and vegetable expenditures, expenditure shares, variety and purchase decisions were affected by the initiation and conclusion, as well as any persistent effects of the program. Changes in fruit and vegetable purchase behaviors due to Double Up Food Bucks in a supermarket serving a low-income, predominantly Hispanic community in Detroit, Michigan were evaluated using a difference in difference fixed effects estimation strategy. We find that the Double Up Food Bucks program increased vegetable expenditures, fruit and vegetable expenditure shares, and variety of fruits and vegetables purchased but the effects were modest and not sustainable without the financial incentive. Fruit expenditures and the fruit and vegetable purchase decision were unaffected by the program. This study provides valuable insight on how a nutrition program influences a low-income, urban, Hispanic community's fruit and vegetable purchase behavior. Policy recommendations include either removing or lowering the purchase hurdle for incentive eligibility and dropping the Michigan grown requirement to better align with the customers' preferences for fresh fruits and vegetables.

In the United States, marijuana is the most commonly used illicit drug. Its prevalence is growing, particularly among young adults. Behavioral economic indices of the relative reinforcing efficacy (RRE) of substances have been used to examine the appeal of licit (e.g., alcohol) and illicit (e.g., heroin) drugs. The present study is the first to use an experimental, simulated purchasing task to examine the RRE of marijuana. Young-adult (M age = 21.64 years) recreational marijuana users (N = 59) completed a computerized marijuana purchasing task designed to generate demand curves and the related RRE indices (e.g., intensity of demand-purchases at lowest price; Omax-max. spent on marijuana; Pmax-price at which marijuana expenditure is max). Participants "purchased" high-grade marijuana across 16 escalating prices that ranged from $0/free to $160/joint. They also provided 2 weeks of real-time, ecological momentary assessment reports on their marijuana use. The purchasing task generated multiple RRE indices. Consistent with research on other substances, the demand for marijuana was inelastic at lower prices but became elastic at higher prices, suggesting that increases in the price of marijuana could lessen its use. In regression analyses, the intensity of demand, Omax, and Pmax, and elasticity each accounted for significant variance in real-time marijuana use. These results provide support for the validity of a simulated marijuana purchasing task to examine marijuana's reinforcing efficacy. This study highlights the value of applying a behavioral economic framework to young-adult marijuana use and has implications for prevention, treatment, and policies to regulate marijuana use.

The purpose of this study was to test the impact of distributing coupons redeemable at farmers markets plus an educational intervention on fruit and vegetable (F&V) purchase and consumption in overweight patients with type 2 diabetes (T2DM). Seventy-eight participants with T2DM being followed at Jacobi Medical Center, a large public hospital in the Bronx, New York, were randomized to receive the standard of care or a 1-hour session focused on benefits of F&V consumption and $6 in coupons. Questionnaires assessed demographics, F&V intake, and farmers market purchasing at baseline and 12 weeks. Clinical parameters were obtained through chart review at baseline and at 12 weeks. Participants were predominantly Latino, females, and low income. At 12 weeks, there was a statistically significant increase in the number of participants in the intervention arm who reported purchasing from a farmers market. In addition, there was a minimal increase in fresh fruit intake in the intervention arm at 12 weeks. Focused education combined with a small economic incentive resulted in an increase in purchasing behavior and fresh fruit intake per day. A more intense behavioral intervention combined with increased access may result in a significant impact on obesity and diabetes, particularly among low-income and racially diverse communities.

2010-01-01

This article examines the influences on the purchasing decisions of fruit and vegetable consumers and presents findings from a survey conducted with 385 respondents living in urban areas in Istanbul, Turkey. It uses a binary logistic model to estimate factor effects in organic fruit and vegetable purchasing in Turkey. The results indicate that concern for human health and safety is a key factor that influences consumer preferences for organic food. Findings will help organic product suppliers understand the key factors influencing consumer purchasing and consumption behaviors.

Determinants of consumer behavior related to organic foods.

PubMed

Shepherd, Richard; Magnusson, Maria; Sjödén, Per-Olow

2005-06-01

There have been many studies of what influences consumers in their decisions to purchase or consume organic foods, mainly concerned with fresh organic foods. These show a discrepancy between attitudes and behavior with people being positive about organic foods but often not purchasing them. This discrepancy seems to be explained by the fact that consumers do not consider "organically produced" to be an important purchase criterion, that organic foods are not perceived to surpass conventional foods regarding taste and shelf life (two qualities rated to be of great importance), and because of the perceived premium prices of organic foods. In two Swedish studies, health benefits were demonstrated to be more strongly related to attitudes and behavior toward organic foods than were perceived environmental benefits. A new European Union (EU) project will investigate the influences on both fresh and processed organic foods and investigate the role of moral, ethical, and affective influences on choice across eight EU countries.

Using a UK Virtual Supermarket to Examine Purchasing Behavior Across Different Income Groups in the United Kingdom: Development and Feasibility Study

Waterlander, Wilma Elzeline; Rayner, Mike; Scarborough, Peter

2017-01-01

Background The majority of food in the United Kingdom is purchased in supermarkets, and therefore, supermarket interventions provide an opportunity to improve diets. Randomized controlled trials are costly, time-consuming, and difficult to conduct in real stores. Alternative approaches of assessing the impact of supermarket interventions on food purchases are needed, especially with respect to assessing differential impacts on population subgroups. Objective The aim of this study was to assess the feasibility of using the United Kingdom Virtual Supermarket (UKVS), a three-dimensional (3D) computer simulation of a supermarket, to measure food purchasing behavior across income groups. Methods Participants (primary household shoppers in the United Kingdom with computer access) were asked to conduct two shopping tasks using the UKVS and complete questionnaires on demographics, food purchasing habits, and feedback on the UKVS software. Data on recruitment method and rate, completion of study procedure, purchases, and feedback on usability were collected to inform future trial protocols. Results A total of 98 participants were recruited, and 46 (47%) fully completed the study procedure. Low-income participants were less likely to complete the study (P=.02). Most participants found the UKVS easy to use (38/46, 83%) and reported that UKVS purchases resembled their usual purchases (41/46, 89%). Conclusions The UKVS is likely to be a useful tool to examine the effects of nutrition interventions using randomized controlled designs. Feedback was positive from participants who completed the study and did not differ by income group. However, retention was low and needs to be addressed in future studies. This study provides purchasing data to establish sample size requirements for full trials using the UKVS. PMID:28993301

To assess trends and correlates of youth cigarette purchasing behavior on the Internet. In 2000-2001, Roswell Park Cancer Institute conducted a survey asking 7,019 ninth grade students in Erie and Niagara Counties in New York State about their tobacco use and purchasing habits, including use of the Internet to buy cigarettes. The 2004-2005 survey is a replication of the 2000-2001 survey. Both surveys used an anonymous, self-administered questionnaire survey. These data were combined in order to examine trends in youth smoking behavior. Students surveyed in 2004-2005 were 2.6 times more likely (95% CI: 1.5, 4.6) to have purchased cigarettes over the Internet in the 30 days prior to the survey than those surveyed in 2001 (5.2% to 1.6%); however, the intention to use the Internet as a cigarette source in the future did not change between survey periods. Youth online cigarette purchasing has increased but intention to use the Internet to purchase cigarettes in the future has remained the same, suggesting that this trend may be reaching a plateau. Recent public efforts to reduce online cigarette sales will need to be evaluated in order to determine which policy or combination of policies are most effective.

Behavioral economic substitutability of e-cigarettes, tobacco cigarettes, and nicotine gum.

Johnson, Matthew W; Johnson, Patrick S; Rass, Olga; Pacek, Lauren R

The public health impact of e-cigarettes may depend on their substitutability for tobacco cigarettes. Dual users of e-cigarettes and tobacco cigarettes completed purchasing tasks in which they specified daily use levels under hypothetical conditions that varied the availability and price of e-cigarettes, tobacco cigarettes, and nicotine gum (for those with nicotine gum experience). When either e-cigarettes or tobacco cigarettes were the only available commodity, as price per puff increased, purchasing decreased, revealing similar reinforcement profiles. When available concurrently, as the price of tobacco puffs increased, purchasing of tobacco puffs decreased while purchasing of fixed-price e-cigarette puffs increased. Among those with nicotine gum experience, when the price of tobacco puffs was closest to the actual market value of tobacco puffs, e-cigarette availability decreased median tobacco puff purchases by 44% compared to when tobacco was available alone. In contrast, nicotine gum availability caused no decrease in tobacco puff purchases. E-cigarettes may serve as a behavioral economic substitute for tobacco cigarettes, and may be a superior substitute compared to nicotine gum in their ability to decrease tobacco use. Although important questions remain regarding the health impacts of e-cigarettes, these data are consistent with the possibility that e-cigarettes may serve as smoking cessation/reduction aids.

To compare changes in food-purchasing knowledge, self-efficacy, and behavior after viewing nutrition education videos among Los Angeles, California Latinas responsible for household grocery shopping. From February to May 2015, a convenience sample of 113 Latinas watched 1 video (El Carrito Saludable) featuring MyPlate guidelines applied to grocery shopping (1-video intervention) and another convenience sample of 105 Latinas watched 2 videos (El Carrito Saludable and Ser Consciente), the latter featuring mindfulness to support attention and overcome distractions while grocery shopping (2-video intervention). We administered questionnaires before and after intervention. A preselected sample in each intervention condition (n = 72) completed questionnaires at 2-months after intervention and provided grocery receipts (before and 2-months after intervention). Knowledge improved in both intervention groups (P < .001). The 2-video group improved more in self-efficacy and use of a shopping list (both P < .05) and purchased more healthy foods (d = 0.60; P < .05) at 2 months than did the 1-video group. Culturally tailored videos that model food-purchasing behavior and mindfulness show promise for improving the quality of foods that Latinas bring into the home.

The aim of the present research is to examine the relation between depletion sensitivity - a novel construct referring to the speed or ease by which one's self-control resources are drained - and snack purchase behavior. In addition, interactions between depletion sensitivity and the goal to lose weight on snack purchase behavior were explored. Participants included in the study were instructed to report every snack they bought over the course of one week. The dependent variables were the number of healthy and unhealthy snacks purchased. The results of the present study demonstrate that depletion sensitivity predicts the amount of unhealthy (but not healthy) snacks bought. The more sensitive people are to depletion, the more unhealthy snacks they buy. Moreover, there was some tentative evidence that this relation is more pronounced for people with a weak as opposed to a strong goal to lose weight, suggesting that a strong goal to lose weight may function as a motivational buffer against self-control failures. All in all, these findings provide evidence for the external validity of depletion sensitivity and the relevance of this construct in the domain of eating behavior. Copyright © 2015 Elsevier Ltd.

Virtual stores can be used to identify influences on consumer shopping behavior. Deception is one technique that may be used to attempt to increase the realism of virtual stores. The objective of the experiment was to test whether the purchasing behavior of participants in a virtual shopping task varied based on whether they were told that they would receive the products they selected in a virtual convenience store (a form of deception) or not. We recruited a US national sample of 402 adult current smokers by email from an online panel of survey participants. They completed a fully automated randomized virtual shopping experiment with a US $15 or US $20 budget in a Web-based virtual convenience store. We told a random half of participants that they would receive the products they chose in the virtual store or the cash equivalent (intervention condition), and the other random half simply to conduct a shopping task (control condition). We tested for differences in demographics, tobacco use behaviors, and in-store purchases (outcome variable, assessed by questionnaire) by experimental condition. The characteristics of the participants (398/402, 99.0% with complete data) were comparable across conditions except that the intervention group contained slightly more female participants (103/197, 52.3%) than the control group (84/201, 41.8%; P=.04). We did not find any other significant differences in any other demographic variables or tobacco use, or in virtual store shopping behaviors, including purchasing any tobacco (P=.44); purchasing cigarettes (P=.16), e-cigarettes (P=.54), cigars (P=.98), or smokeless tobacco (P=.72); amount spent overall (P=.63) or on tobacco (P=.66); percentage of budget spent overall (P=.84) or on tobacco (P=.74); number of total items (P=.64) and tobacco items purchased (P=.54); or total time spent in the store (P=.07). We found that telling participants that they will receive the products they select in a virtual store did not influence their purchases. This finding suggests that deception may not affect consumer behavior and, as a result, may not be necessary in virtual shopping experiments. ©Lauren McCarl Dutra, James Nonnemaker, Nathaniel Taylor, Annice E Kim.

To compare the habits of United States (US) soft contact lens (SCL) wearers who bought SCLs from their eye care practitioner (ECP), on the internet/telephone, or at retail (not where they were examined) to test the effect of proximity to the prescriber on SCL wear and care practices. Adult SCL wearers completed an adapted Contact Lens Risk Survey (CLRS) online that queried items related to risk factors for SCL-related complications. Responses from subjects who purchased at the ECP, via the internet/telephone, or at a retail store were compared (Chi-Square). Purchase sources were: ECP 646 (67%, 44±12 yrs, 17% male), Retail 104 (11%, 45±13 yrs, 28% male), and Internet/telephone 218 (23%, 45±12 yrs, 18% male); age (p=0.51), gender (p=0.021). Internet purchasers had fewer annual eye exams (79% ECP, 83% retail, 66% internet/telephone, p=0.007), purchased more hydrogel SCLs (34% ECP, 29% retail, 45% internet/telephone, p=0.0034), and paid for SCLs with insurance less often (39% ECP, 29% retail, 19% internet/telephone, p<0.0001). Other behaviors were similar across groups (p>0.05). In this sample, the purchase location of SCL wearers had limited impact on known risk factors for SCL-related complications. Internet purchasers reported less frequent eye exams and were more likely to be wearing hydrogel SCLs. Closer access to the ECP through in-office SCL purchase did not improve SCL habits or reduce the prevalence of risk behaviors. Copyright © 2016 British Contact Lens Association.

Prevalence data were collected from official microbiological records monitoring four selected foodborne pathogens (Salmonella, Listeria monocytogenes, Escherichia coli O157:H7, and Campylobacter jejuni) in raw milk sold by self-service vending machines in seven Italian regions (60,907 samples from 1,239 vending machines) from 2008 to 2011. Data from samples analyzed by both culture-based and real-time PCR methods were collected in one region. One hundred raw milk consumers in four regions were interviewed while purchasing raw milk from vending machines. One hundred seventy-eight of 60,907 samples were positive for one of the four foodborne pathogens investigated: 18 samples were positive for Salmonella, 83 for L. monocytogenes, 24 for E. coli O157:H7, and 53 for C. jejuni in the seven regions investigated. No significant differences in prevalence were found among regions, but a significant increase in C. jejuni prevalence was observed over the years of the study. A comparison of the two analysis methods revealed that real-time PCR was 2.71 to 9.40 times more sensitive than the culture-based method. Data on consumer habits revealed that some behaviors may enhance the risk of infection linked to raw milk consumption: 37% of consumers did not boil milk before consumption, 93% never used an insulated bag to transport raw milk home, and raw milk was consumed by children younger than 5 years of age. These results emphasize that end-product controls alone are not sufficient to guarantee an adequate level of consumer protection. The beta distribution of positive samples in this study and the data on raw milk consumer habits will be useful for the development of a national quantitative risk assessment of Salmonella, L. monocytogenes, E. coli O157, and C. jejuni infection associated with raw milk consumption.

Helping E-Commerce Consumers Make Good Purchase Decisions: A User Reviews-Based Approach

NASA Astrophysics Data System (ADS)

Zhang, Richong; Tran, Thomas T.

Online product reviews provided by the consumers, who have previously purchased and used some particular products, form a rich source of information for other consumers who would like to study about these products in order to make their purchase decisions. Realizing this great need of consumers, several e-commerce web sites such as Amazon.com offer facilities for consumers to review products and exchange their purchase opinions. Unfortunately, reading through the massive amounts of product reviews available online from many e-communities, forums and newsgroups is not only a tedious task but also an impossible one. Indeed, nowadays consumers need an effective and reliable method to search through those huge sources of information and sort out the most appropriate and helpful product reviews. This paper proposes a model to discover the helpfulness of online product reviews. Product reviews can be analyzed and ranked by our scoring system and those reviews that may help consumers better than others will be found. In addition, we compare our model with a number of machine learning techniques. Our experimental results confirm that our approach is effective in ranking and classifying online product reviews.

Unhealthy food advertising is an important contributor to childhood obesity. The purpose of this pilot study was to evaluate the impact of a food advertising literacy program that incorporated components of health-promoting media literacy education on fifth-grade children. Participants were 140 fifth-graders (10 and 11 years old) from one school who were randomly divided into three groups. Experimental Group A received a food advertising literacy program, experimental Group B received a comparable knowledge-based nutrition education program and the control group did not receive any nutrition education. Repeated measures analysis of variance and multivariate analysis of covariance were used to test mean changes between pretest, posttest and follow-up on participants' nutritional knowledge, food advertising literacy and food purchasing behavior. Results showed that, as compared with Group B and the control groups, Group A showed higher nutritional knowledge, food advertising literacy and food purchasing behavior at post-intervention, but had no significant improvements in nutritional knowledge and food purchasing behavior at the 1-month follow-up. Although some improvements were observed, future studies should consider a long-term, settings-based approach that is closely connected with children's daily lives, as this might be helpful to solidify children's skills in recognizing, evaluating and understanding unhealthy food advertising. © The Author 2016.

Consumer brand choice: individual and group analyses of demand elasticity.

Oliveira-Castro, Jorge M; Foxall, Gordon R; Schrezenmaier, Teresa C

2006-03-01

Following the behavior-analytic tradition of analyzing individual behavior, the present research investigated demand elasticity of individual consumers purchasing supermarket products, and compared individual and group analyses of elasticity. Panel data from 80 UK consumers purchasing 9 product categories (i.e., baked beans, biscuits, breakfast cereals, butter, cheese, fruit juice, instant coffee, margarine and tea) during a 16-week period were used. Elasticity coefficients were calculated for individual consumers with data from all or only 1 product category (intra-consumer elasticities), and for each product category using all data points from all consumers (overall product elasticity) or 1 average data point per consumer (interconsumer elasticity). In addition to this, split-sample elasticity coefficients were obtained for each individual with data from all product categories purchased during weeks 1 to 8 and 9 to 16. The results suggest that: 1) demand elasticity coefficients calculated for individual consumers purchasing supermarket food products are compatible with predictions from economic theory and behavioral economics; 2) overall product elasticities, typically employed in marketing and econometric research, include effects of interconsumer and intraconsumer elasticities; 3) when comparing demand elasticities of different product categories, group and individual analyses yield similar trends; and 4) individual differences in demand elasticity are relatively consistent across time, but do not seem to be consistent across products. These results demonstrate the theoretical, methodological, and managerial relevance of investigating the behavior of individual consumers.

A behavioral economic analysis of the nonmedical use of prescription drugs among young adults.

2016-02-01

The nonmedical use of prescription drugs is a widely recognized public health issue, and young adults are particularly vulnerable to their use. Behavioral economic drug purchase tasks capture an individual's strength of desire and motivation for a particular drug. We examined young adult prescription drug purchase and consumption patterns using hypothetical behavioral economic purchase tasks for prescription sedatives/tranquilizers, stimulants, and opiate pain relievers. We also examined relations between demand, use frequency, and Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) substance use disorder (SUD) symptoms, and sex differences in these relations. Undergraduate students who endorsed past-year prescription drug use (N = 393) completed an online questionnaire for course credit. Measures assessed substance use frequency and DSM-5 SUD symptoms. Hypothetical purchase tasks for sedatives, stimulants, and pain relievers assessed participants' consumption and expenditure patterns for these substances across 25 prices. Past-year prescription sedative, stimulant, and pain reliever use was endorsed by 138, 258, and 189 participants, respectively. Among these users, consumption for their respective substance decreased as a function of ascending price, as expected. Demand indices for a prescription drug were associated with each other and with use frequency and SUD symptoms, with variability across substances but largely not by sex. In addition, demand for prescription pain relievers differentially predicted symptoms independent of use, with differences for females and males. In conclusion, hypothetical consumption and expenditure patterns for prescription drugs were generally well described by behavioral economic demand curves, and the observed associations with use and SUD symptoms provide support for the utility of prescription drug purchase tasks.

Behavioral economic substitution between conventional cigarettes and e-cigarettes differs as a function of the frequency of e-cigarette use.

PubMed

Snider, Sarah E; Cummings, K Michael; Bickel, Warren K

2017-08-01

Models measuring the interactions between consumption of conventional cigarettes and electronic cigarettes (e-cigarettes) in the marketplace are becoming vital forecast tools as the popularity of e-cigarettes increases and policy on tobacco products changes. Behavioral economics, which involves the integration of psychology and consumer demand, can be used to measure individuals' purchase behavior under different marketplace conditions. Our goal was to measure hypothetical conventional cigarette and e-cigarette purchasing among smokers with varying e-cigarette use patterns. Daily cigarette smokers were recruited using Amazon Mechanical Turk, an online crowdsourcing tool. Participants were asked about their frequency of e-cigarette use and to complete hypothetical single and cross-commodity purchase tasks. Frequency of e-cigarette use differentially affected how individuals consumed both conventional and e- cigarettes in different hypothetical marketplace conditions. The present study demonstrates four main findings: 1) the demand for conventional cigarettes was the lowest in those with greater frequency of e-cigarette use, 2) the demand for e-cigarettes was the highest in those with greater frequency of e-cigarette use, 3) when both products were available together, daily e-cigarette users purchased more e-cigarettes, but e-cigarettes served as a substitute for cigarettes in all groups regardless of frequency of use, and 4) the demand for conventional cigarette demand was lower in frequent e-cigarette users when e-cigarettes were concurrently available. Together, these data suggest that price and marketplace conditions will impact purchasing behavior of conventional and e-cigarettes users heterogeneously. Therefore, frequency of use patterns should be considered when implementing novel policies and/or marketplace changes. Copyright © 2017 Elsevier B.V. All rights reserved.

The importance of creating healthier work environments by providing healthy foods and beverages in worksite cafeterias, in on-site vending machines, and at meetings and conferences is drawing increasing attention. Large employers, federal and state governments, and hospital systems are significant purchasers and providers of food and beverages. The American Heart Association, federal government, and other organizations have created procurement standards to guide healthy purchasing by these entities. There is a need to review how procurement standards are currently implemented, to identify important minimum criteria for evaluating health and purchasing outcomes, and to recognize significant barriers and challenges to implementation, along with success stories. The purpose of this policy paper is to describe the role of food-and-beverage environment and procurement policy standards in creating healthier worksite environments; to review recently created national model standards; to identify elements across the standards that are important to consider for incorporation into policies; and to delineate issues to address as standards are implemented across the country. © 2014 International Life Sciences Institute.

A framework for understanding grocery purchasing in a low-income urban environment.

2013-05-01

Research demonstrates that food desert environments limit low-income shoppers' ability to purchase healthy foods, thereby increasing their likelihood of diet-related illnesses. We sought to understand how individuals in an urban American food desert make grocery-purchasing decisions, and specifically why unhealthy purchases arise. Analysis is based on ethnographic data from participant observation, 37 in-depth interviews, and three focus groups with low-income, primarily African American shoppers with children. We found participants had detailed knowledge of and preference for healthy foods, but the obligation to consistently provide food for their families required them to apply specific decision criteria which, combined with structural qualities of the supermarket environment, increased unhealthy purchases and decreased healthy purchases. Applying situated cognition theory, we constructed an emic model explaining this widely shared grocery-purchasing decision process and its implications. This context-specific understanding of behavior suggests that multifaceted, system-level approaches to intervention are needed to increase healthy purchasing in food deserts.

Racial and Ethnic Differences in What Smokers Report Paying for Their Cigarettes

Introduction: Smoking rates and tobacco-related health problems vary by race and ethnicity. We explore whether cigarette prices, a determinant of tobacco use, differ across racial and ethnic groups, and whether consumer behaviors influence these differences. Methods: We used national Tobacco Use Supplement data from 23 299 adult smokers in the United States to calculate average reported cigarette pack prices for six racial and ethnic groups. Using multivariate regression models, we analyzed the independent effect of race and ethnicity on price, and whether these effects changed once indicators of carton purchasing, menthol use, Indian reservation purchase, and state market prices were incorporated. Results: American Indians and whites pay similar amounts and report the lowest prices. Blacks, Hispanics, and Asians reported paying $0.42, $0.68, and $0.89 more for a pack of cigarettes than whites. After accounting for differences in consumer behaviors, these gaps shrunk to $0.27, $0.29, and $0.27, respectively, while American Indians paid $0.38 more than whites. Pack buying was associated with $0.99 higher per-pack prices than carton buying, which was most common among whites. Additionally, people who purchased off an Indian reservation reporting paying $1.54 more than those who purchased on reservation. Conclusions: Average reported cigarette prices vary by race and ethnicity, in part due to differences in product use and purchase location. Tobacco price policies, especially those that target low prices for multipack products or on Indian reservations may increase the prices paid by whites and American Indians, who smoke at the highest rates and pay the least per pack. Implications: This study examines differences in reported prices paid by different racial and ethnic groups, using recent, national data from the United States. Results indicating that racial and ethnic groups that smoke at the highest rates (American Indians and whites) also pay the least are consistent with evidence that price is a key factor in cigarette use. Additional analysis finds that cigarette purchasing behaviors, especially carton buying and purchasing on Indian reservations, partially account for the documented price differences, and suggest that policies focused on bulk purchases (carton, multipack) and reservation prices have strong tobacco control potential.

This paper reports the results of two experiments using a laboratory analog to examine the influence of taxes and subsidies on youth's snack food purchases when alone (Experiment 1) and when in the presence of a same-gender peer (Experiment 2). Adolescents (12-14-years-old) completed a purchasing task, during which prices of snack foods were manipulated, either alone in Experiment 1 (N=37) or in the presence of an unfamiliar peer in Experiment 2 (N=52). In both experiments, purchases of unhealthy snacks decreased and purchases of healthy snacks increased when the price of unhealthy snacks were taxed (increased). In Experiment 1 (alone), participants did not purchase more healthy snacks when the price of these snacks were subsidized (decreased). However, in Experiment 2 (when participants were in the presence of a peer), participants purchased more healthy snacks when these snacks were subsidized. Taxes and subsidies affect adolescents' snack purchasing, as does the presence of peers. The results of this study highlight factors that influence healthy and unhealthy snack purchasing behavior in young adolescents. Copyright © 2012. Published by Elsevier Ltd.

Ergonomics in ultrasound equipment: productivity and patient throughput.

PubMed

Atjak, A; Gattinella, J A

1989-01-01

The important issues to consider when purchasing ultrasound equipment are: image quality, speed of interface, controls that are obvious, quick or slow configuring, a narrow or wide triangle of interest, fast or slow function shift capability, the amount of layering, color that is muted or not muted, whether the controls are back lit, easily managed cables and probes, and whether the machine is pleasant to operate and easy to learn. All these factors will provide you with some idea of a system's productivity and assist the buyer in making a purchasing decision. Consider these points as a checklist when shopping for an ultrasound system, especially when the radiology manager is concerned about throughput and the bottom line as well as diagnostic information quality.

Consumer choice: Linking consumer intentions to actual purchase of GM labeled food products.

PubMed

Sleenhoff, Susanne; Osseweijer, Patricia

2013-01-01

With a mandatory labeling scheme for GM food in Europe since 2004 measuring actual consumer choice in practice has become possible. Anticipating Europeans negative attitude toward GM food, the labeling was enforced to allow consumers to make an informed choice. We studied consumers actual purchase behavior of GM food products and compared this with their attitude and behavioral intention for buying GM food. We found that despite a majority of consumers voicing a negative attitude toward GM food over 50% of our European respondents stated that they did not actively avoid the purchase of GM food and 6% actually purchased one of the few available GM labeled food products in the period between September 2006 and October 2007. Our results imply that a voiced negative attitude of consumers in responses to questionnaires about their intentions is not a reliable guide for what they actually do in supermarkets. We conclude that the assumption of a negative attitude with regard to GM food is at least in part construed.

Evaluating Retailer Behavior in Preventing Youth Access to Harmful Legal Products: A Feasibility Test*

2008-01-01

This paper reports results from a feasibility study of a community effort to reduce the availability of legal products that youth can use to get “high”. The study evaluated the potential of youth purchase attempts to detect actual changes in retail availability of harmful legal products. These results were triangulated with self-reports from retailers themselves about their own policies and practices. Before the intervention less than half of retailers reported using any of six possible strategies identified as ways to reduce youth access to harmful products and less than 7% of baseline youth attempts to purchase potentially harmful legal products were refused or questioned. After the low dosage intervention, retailers reported increased use of three strategies and a statistically significant increase in the percentage of purchase attempts that were either questioned or refused by retail clerks. These findings (1) demonstrate the potential feasibility of retailer focused environmental strategies and (2) support continued use of youth purchase attempts as a measure of actual retailer behavior.

Reducing the illegal sale of cigarettes to minors.

PubMed

Altman, D G; Foster, V; Rasenick-Douss, L; Tye, J B

1989-01-06

This study reports on an effort to stop the illegal sale of cigarettes to minors. In Santa Clara County, Calif, 412 stores and 30 vending machines were visited by 18 minors aged 14 through 16 years with the intent to purchase cigarettes; they were successful at 74% of the stores and 100% of the vending machines. After an aggressive six-month campaign using communitywide media, direct merchant education, contact with the chief executive officers of chain stores and franchise operations owned by major companies, and grassroots work with community organizations, the percentage of stores with illegal over-the-counter sale of cigarettes to minors was reduced to 39%. Sales from vending machines were not reduced. While much remains to be accomplished in stopping the illegal sale of tobacco to minors, data from this study illustrate that a well-designed community and merchant education campaign can significantly reduce such sales.

Use of the think aloud method to examine fruit and vegetable purchasing behaviors among low-income African American women.

Reicks, Marla; Smith, Chery; Henry, Helen; Reimer, Kathy; Atwell, Janine; Thomas, Ruth

2003-01-01

The purpose of this report is to describe the development and implementation of the think aloud method in relation to fruit and vegetable purchasing behaviors of low-income African American mothers. Women (n = 70) were audiotaped as they thought aloud while selecting fruits and vegetables during a routine shopping trip. Audiotapes were transcribed, text was coded, and coded text was sorted using a database software program. Data were analyzed using content analysis procedures. The method was found to be useful in its ability to provide verbalization data for the majority of the women in the sample that reflected a typical shopping experience, were not excessively affected by the presence of the investigator, and captured information processing in relation to salient factors that influenced food purchasing decisions. Because a few women indicated that the method itself may have influenced behavior, future research is needed to test the reactivity of the think aloud method and its relationship to final choice of products.

2013-06-01

We examined the relationship between cigarette excise tax increases and tax-avoidant purchasing behaviors among New York City adult smokers. We analyzed data from the city's annual Community Health Survey to assess changes in rates of tax avoidance over time (2003-2010) and smokers' responses to the 2008 state cigarette tax increase. Multivariable logistic regression analysis identified correlates of buying more cigarettes on the street in response to the increase. After the 2002 tax increase, the percentage of smokers engaged in tax-avoidant behavior decreased with time from 30% in 2003 to 13% in 2007. Following the 2008 tax increase, 21% of smokers reported buying more cigarettes from another person on the street. Low-income, younger, Black, and Hispanic smokers were more likely than respondents with other sociodemographic characteristics to purchase more cigarettes on the street. To maximize public health impact, cigarette tax increases should be paired with efforts to limit the flow of untaxed cigarettes entering jurisdictions with high cigarette pack prices.

Online purchases in an Infocomm sophisticated society.

Goby, Valerie Priscilla

2006-08-01

This paper presents a preliminary investigation of attitude and intention in relation to online shopping in Singapore. Singaporeans display high levels of Infocomm proficiency, the result of many intense government initiatives to transform the country into an Intelligent Community. Does this Internet embracing environment enhance attitude and intention to online shopping? This study considers the links between personal consequences, subjective norms, behavioral control, and personal innovativeness with attitude and intention among Singaporeans. It uses a model based on the Theory of Planned Behavior and makes some initial comparisons of its findings with those of existing studies. The effects of behavioral control and intention on actual purchase behavior are not investigated. Findings permit the tentative proposition that level of Infocomm knowledge impacts on attitude and intention.

Ductile and brittle transition behavior of titanium alloys in ultra-precision machining.

PubMed

Yip, W S; To, S

2018-03-02

Titanium alloys are extensively applied in biomedical industries due to their excellent material properties. However, they are recognized as difficult to cut materials due to their low thermal conductivity, which induces a complexity to their deformation mechanisms and restricts precise productions. This paper presents a new observation about the removal regime of titanium alloys. The experimental results, including the chip formation, thrust force signal and surface profile, showed that there was a critical cutting distance to achieve better surface integrity of machined surface. The machined areas with better surface roughness were located before the clear transition point, defining as the ductile to brittle transition. The machined area at the brittle region displayed the fracture deformation which showed cracks on the surface edge. The relationship between depth of cut and the ductile to brittle transaction behavior of titanium alloys in ultra-precision machining(UPM) was also revealed in this study, it showed that the ductile to brittle transaction behavior of titanium alloys occurred mainly at relatively small depth of cut. The study firstly defines the ductile to brittle transition behavior of titanium alloys in UPM, contributing the information of ductile machining as an optimal machining condition for precise productions of titanium alloys.

Finkelstein, Eric A; Strombotne, Kiersten L; Chan, Nadine L; Krieger, James

2011-02-01

As part of a comprehensive effort to stem the rise in obesity, King County, Washington, enforced a mandatory menu-labeling regulation requiring all restaurant chains with 15 or more locations to disclose calorie information at the point of purchase beginning in January 2009. The purpose of this study is to quantify the impact of the King County regulation on transactions and purchasing behavior at one Mexican fast-food chain with locations within and adjacent to King County. To examine the effect of the King County regulation, a difference-in-difference approach was used to compare total transactions and average calories per transaction between seven King County restaurants and seven control locations focusing on two time periods: one period immediately following the law until the posting of drive-through menu boards (January 2009 to July 2009) and a second period following the drive-through postings (August 2009 through January 2010). Analyses were conducted in 2010. No impact of the regulation on purchasing behavior was found. Trends in transactions and calories per transaction did not vary between control and intervention locations after the law was enacted. In this setting, mandatory menu labeling did not promote healthier food-purchasing behavior. Copyright © 2011 American Journal of Preventive Medicine. Published by Elsevier Inc. All rights reserved.

2010-01-01

The purpose of this study was to examine consumers' behaviors toward ready-to-eat foods and to develop ready-to-eat food market segmentation in Korea. The food-related lifestyle and purchase behaviors of ready-to-eat foods were evaluated using 410 ready-to-eat food consumers in the Republic of Korea. Four factors were extracted by exploratory factor analysis (health-orientation, taste-orientation, convenience-orientation, and tradition-orientation) to explain the ready-to eat food consumers' food-related lifestyles. The results of cluster analysis indicated that "tradition seekers" and "convenience seekers" should be regarded as the target segments. Chi-square tests and t-tests of the subdivided groups showed there were significant differences across marital status, education level, family type, eating-out expenditure, place of purchase, and reason for purchase. In conclusion, the tradition seekers consumed more ready-to-eat foods from discount marts or specialty stores and ate them between meals more often than the convenience seekers. In contrast, the convenience seekers purchased more ready-to-eat foods at convenience stores and ate them as meals more often than the tradition seekers. These findings suggest that ready-to-eat food market segmentation based on food-related lifestyles can be applied to develop proper marketing strategies. PMID:20827350

2011-01-01

The purpose of this study was to understand fresh fruit and vegetable purchasing habits among senior farmers' market shoppers using the theory of planned behavior. A survey instrument was developed to collect information on seniors' fruit and vegetable purchasing habits. A convenience sample of seniors shopping at farmers' markets was employed. A total of 184 surveys were collected. Respondents were divided into two groups based on response to a question of whether they received Senior Farmers' Market Nutritional Program (SFMNP) checks: 35 were on the SFMNP and 149 were not. Results indicated attitudes, subjective norms (SN), and perceived behavioral control (PBC) were all significantly correlated with intentions at the p < 0.01 level. Attitude had the strongest association with intentions (0.730), followed by PBC (0.666) and SN (0.587). Regression analysis was significant and explained 66% of the variance (F = 86.151, p < 0.001, adjusted R square = 0.656). Results indicated attitude to be the strongest predictor of seniors' intentions to purchase more fresh fruits and vegetables at farmers' markets. Senior programs may find this information useful when promoting fresh fruits and vegetables for senior citizens. These findings may also benefit farmers' markets while promoting fresh fruits and vegetables.

Waste reduction through consumer education. Final report

DOE Office of Scientific and Technical Information (OSTI.GOV)

Harrison, E.Z.

The Waste Reduction through Consumer Education research project was conducted to determine how environmental educational strategies influence purchasing behavior in the supermarket. The objectives were to develop, demonstrate, and evaluate consumer education strategies for waste reduction. The amount of waste generated by packaging size and form, with an adjustment for local recyclability of waste, was determined for 14 product categories identified as having more waste generating and less waste generating product choices (a total of 484 products). Using supermarket scan data and shopper identification numbers, the research tracked the purchases of shoppers in groups receiving different education treatments for 9more » months. Statistical tests applied to the purchase data assessed patterns of change between the groups by treatment period. Analysis of the data revealed few meaningful statistical differences between study groups or changes in behavior over time. Findings suggest that broad brush consumer education about waste reduction is not effective in changing purchasing behaviors in the short term. However, it may help create a general awareness of the issues surrounding excess packaging and consumer responsibility. The study concludes that the answer to waste reduction in the future may be a combination of voluntary initiatives by manufacturers and retailers, governmental intervention, and better-informed consumers.« less

Children’s Eating Behavior: The Importance of Nutrition Standards for Foods in Schools

PubMed Central

Bevans, Katherine B.; Sanchez, Betty; Teneralli, Rachel; Forrest, Christopher B.

2011-01-01

BACKGROUND To enhance the impact of school nutrition programs on children’s health, more information is needed on the associations between healthy and unhealthy food offerings during school lunch periods and children’s eating behavior. The purpose of this study is to evaluate the contributions of food offerings and participation in school lunch programs on children’s overall (both in- and out-of-school) eating behavior. METHODS A cross-sectional observational study was conducted in which 2039 students in 12 elementary and 10 middle schools reported their eating behavior and the frequencies with which they purchased meals and à la carte items in the school cafeteria. Food service managers from each school provided information on the availability of foods and beverages during school lunch periods. Multilevel regression analyses were conducted to identify school- and student-level predictors of children’s eating behavior. RESULTS The availability of nutritious foods during school lunch periods was associated with healthier eating behavior among students. However, this effect was observed only among children who infrequently purchased à la carte food items, and not among those who were frequent purchasers. CONCLUSION Increased availability of fruits, vegetables, whole grains, and low-fat dairy products as components of school meals may be an effective strategy to promote healthy eating behaviors among children. Improving the nutrition standards for foods offered in competition with federally reimbursable school meals may enhance the positive effects of school meal programs on student eating behavior.

Paradoxically, individuals with food insecurity have been observed to have higher rates of obesity compared with their counterparts with food security. The factors influencing food purchasing behaviors in households with food security vs food insecurity are poorly understood. Using the mixed methods approach of concept mapping, we examined the perceptions and preferences driving the food purchasing behaviors of households with food security vs food insecurity. Twenty-six men and women with food security and 41 men and women with food insecurity from four neighborhoods in Boston, MA, completed the concept mapping process during 2010. Prevalence of overweight and obesity was greater among participants with food insecurity (80.5%) compared with those with food security (61.5%). Participants identified 163 unique factors that influenced their food purchasing behavior. Using multivariate analyses, these factors were grouped into eight unique concepts or clusters that reflected their perceptions of factors hindering healthy eating. Average cluster ratings were similar between participants with food security and food insecurity, suggesting that similar food purchasing behaviors are employed and are perceived similarly in how they hinder or promote healthy eating. The use of emergency food assistance programs may play a role in minimizing the burden of food insecurity while providing access to foods with varying degrees of nutritional quality that may be associated with increased risk of overweight and obesity observed in individuals and households with food insecurity.

2016-01-01

Two studies examined factors influencing cashiers' identification (ID)-checking behavior in order to inform the development of interventions to prevent credit-card fraud. In both studies, research assistants made credit purchases in various stores and noted the cashiers' ID-checking behavior. In the first study, the store type, whether the cashier swiped the credit/debit card, the amount of the purchase, and whether the credit/debit card was signed significantly influenced ID-checking behavior. In the second study, an A-B-A design was used to evaluate the impact of a "Check my ID" prompt placed on the credit/debit card. The prompt increased cashiers' ID-checking behavior from 5.9% at Baseline to 10.3% during the Intervention. When the prompt was removed, the cashiers' ID-checking behavior decreased to 7.2%. Implications for further intervention research to prevent credit-card fraud are discussed.

Using a UK Virtual Supermarket to Examine Purchasing Behavior Across Different Income Groups in the United Kingdom: Development and Feasibility Study.

2017-10-09

The majority of food in the United Kingdom is purchased in supermarkets, and therefore, supermarket interventions provide an opportunity to improve diets. Randomized controlled trials are costly, time-consuming, and difficult to conduct in real stores. Alternative approaches of assessing the impact of supermarket interventions on food purchases are needed, especially with respect to assessing differential impacts on population subgroups. The aim of this study was to assess the feasibility of using the United Kingdom Virtual Supermarket (UKVS), a three-dimensional (3D) computer simulation of a supermarket, to measure food purchasing behavior across income groups. Participants (primary household shoppers in the United Kingdom with computer access) were asked to conduct two shopping tasks using the UKVS and complete questionnaires on demographics, food purchasing habits, and feedback on the UKVS software. Data on recruitment method and rate, completion of study procedure, purchases, and feedback on usability were collected to inform future trial protocols. A total of 98 participants were recruited, and 46 (47%) fully completed the study procedure. Low-income participants were less likely to complete the study (P=.02). Most participants found the UKVS easy to use (38/46, 83%) and reported that UKVS purchases resembled their usual purchases (41/46, 89%). The UKVS is likely to be a useful tool to examine the effects of nutrition interventions using randomized controlled designs. Feedback was positive from participants who completed the study and did not differ by income group. However, retention was low and needs to be addressed in future studies. This study provides purchasing data to establish sample size requirements for full trials using the UKVS. ©Anja Mizdrak, Wilma Elzeline Waterlander, Mike Rayner, Peter Scarborough.

The environmental impact of the Glostavent® anesthetic machine.

PubMed

Eltringham, Roger J; Neighbour, Robert C

2015-06-01

Because anesthetic machines have become more complex and more expensive, they have become less suitable for use in the many isolated hospitals in the poorest countries in the world. In these situations, they are frequently unable to function at all because of interruptions in the supply of oxygen or electricity and the absence of skilled technicians for maintenance and servicing. Despite these disadvantages, these machines are still delivered in large numbers, thereby expending precious resources without any benefit to patients. The Glostavent was introduced primarily to enable an anesthetic service to be delivered in these difficult circumstances. It is smaller and less complex than standard anesthetic machines and much less expensive to produce. It combines a drawover anesthetic system with an oxygen concentrator and a gas-driven ventilator. It greatly reduces the need for the purchase and transport of cylinders of compressed gases, reduces the impact on the environment, and enables considerable savings. Cylinder oxygen is expensive to produce and difficult to transport over long distances on poor roads. Consequently, the supply may run out. However, when using the Glostavent, oxygen is normally produced at a fraction of the cost of cylinders by the oxygen concentrator, which is an integral part of the Glostavent. This enables great savings in the purchase and transport cost of oxygen cylinders. If the electricity fails and the oxygen concentrator ceases to function, oxygen from a reserve cylinder automatically provides the pressure to drive the ventilator and oxygen for the breathing circuit. Consequently, economy is achieved because the ventilator has been designed to minimize the amount of driving gas required to one-seventh of the patient's tidal volume. Additional economies are achieved by completely eliminating spillage of oxygen from the breathing system and by recycling the driving gas into the breathing system to increase the Fraction of Inspired Oxygen (FIO2) at no extra cost. Savings also are accrued when using the drawover breathing system as the need for nitrous oxide, compressed air, and soda lime are eliminated. The Glostavent enables the administration of safe anesthesia to be continued when standard machines are unable to function and can do so with minimal harm to the environment.

A Behavioral Economic Approach to Assessing Demand for Marijuana

PubMed Central

Collins, R. Lorraine; Vincent, Paula C.; Yu, Jihnhee; Liu, Liu; Epstein, Leonard H.

2014-01-01

In the U.S., marijuana is the most commonly used illicit drug. Its prevalence is growing, particularly among young adults. Behavioral economic indices of the relative reinforcing efficacy (RRE) of substances have been used to examine the appeal of licit (e.g., alcohol) and illicit (e.g., heroin) drugs. The present study is the first to use an experimental, simulated purchasing task to examine the RRE of marijuana. Young-adult (M age = 21.64 years) recreational marijuana users (N = 59) completed a computerized marijuana purchasing task designed to generate demand curves and the related RRE indices (e.g., intensity of demand - purchases at lowest price; Omax - max. spent on marijuana; Pmax - price at which marijuana expenditure is max). Participants “purchased” high-grade marijuana across 16 escalating prices that ranged from $0/free to $160/joint. They also provided 2-weeks of real-time, ecological momentary assessment reports on their marijuana use. The purchasing task generated multiple RRE indices. Consistent with research on other substances, the demand for marijuana was inelastic at lower prices but became elastic at higher prices, suggesting that increases in the price of marijuana could lessen its use. In regression analyses, the intensity of demand, Omax and Pmax, and elasticity each accounted for significant variance in real-time marijuana use. These results provide support for the validity of a simulated marijuana purchasing task to examine its reinforcing efficacy. This study highlights the value of applying a behavioral economic framework to young-adult marijuana use and has implications for prevention, treatment, and policies to regulate marijuana use.

Initial Development of a Brief Behavioral Economic Assessment of Alcohol Demand

PubMed Central

Owens, Max M.; Murphy, Cara M.; MacKillop, James

2015-01-01

Due to difficulties with definition and measurement, the role of conscious craving in substance use disorders remains contentious. To address this, behavioral economics is increasingly being used to quantify aspects of an individual’s acute motivation to use a substance. Doing so typically involves the use of a purchase task, in which participants make choices about consuming alcohol or other substances at various prices and multiple indices of alcohol demand are generated. However, purchase tasks can be limited by the time required to administer and score them. In the current study, a brief 3-item measure, designed to capture three important indices of demand that are derived from demand curve modeling (intensity, Omax, and breakpoint), was investigated in a group of 84 heavy drinkers. Participants underwent a cue-reactivity paradigm that is established to increase both conscious craving and alcohol demand on traditional purchase tasks. All three indices of demand for alcohol measured using the abbreviated measure increased significantly in response to alcohol cues, analogous to what has been observed using a traditional purchase task. Additionally, the correlations between these indices and subjective craving were modest-to-moderate, as has been found in studies comparing craving to the indices derived from purchase tasks. These findings suggest that this abbreviated measure may be a useful and efficient way to capture important and distinct aspects of motivation for alcohol. If these results are confirmed, this measure may be able to help increase the portability of behavioral economic indices of demand into novel research and clinical contexts. PMID:27135038

How the elderly and young adults differ in the decision making process of nonprescription medication purchases.

1996-01-01

The study compared elderly and young adults in their behavior and involvement in the decision making process of over-the-counter (OTC) medication purchases. Elderly subjects were more involved in the decision making process to purchase OTC medications compared to young adults. The elderly not only purchase and spend more money on medications but also read OTC labels completely. They requested help from the pharmacist more frequently than young adults. Needs of the elderly in making an OTC medication purchase were different compared to young adults. The two age groups differed on importance rating for several attributes regarding OTC medications, such as; ease of opening the package, child resistant package, side effects of medicine, manufacturer of medicine, print size on package labels, and greater choice of medicine.

Leveraging delay discounting for health: Can time delays influence food choice?

Appelhans, Bradley M; French, Simone A; Olinger, Tamara; Bogucki, Michael; Janssen, Imke; Avery-Mamer, Elizabeth F; Powell, Lisa M

2018-07-01

Delay discounting, the tendency to choose smaller immediate rewards over larger delayed rewards, is theorized to promote consumption of immediately rewarding but unhealthy foods at the expense of long-term weight maintenance and nutritional health. An untested implication of delay discounting models of decision-making is that selectively delaying access to less healthy foods may promote selection of healthier (immediately available) alternatives, even if they may be less desirable. The current study tested this hypothesis by measuring healthy versus regular vending machine snack purchasing before and during the implementation of a 25-s time delay on the delivery of regular snacks. Purchasing was also examined under a $0.25 discount on healthy snacks, a $0.25 tax on regular snacks, and the combination of both pricing interventions with the 25-s time delay. Across 32,019 vending sales from three separate vending locations, the 25-s time delay increased healthy snack purchasing from 40.1% to 42.5%, which was comparable to the impact of a $0.25 discount (43.0%). Combining the delay and the discount had a roughly additive effect (46.0%). However, the strongest effects were seen under the $0.25 tax on regular snacks (53.7%) and the combination of the delay and the tax (50.2%). Intervention effects varied substantially between vending locations. Importantly, time delays did not harm overall vending sales or revenue, which is relevant to the real-world feasibility of this intervention. More investigation is needed to better understand how the impact of time delays on food choice varies across populations, evaluate the effects of time delays on beverage vending choices, and extend this approach to food choices in contexts other than vending machines.

Ample experimental research has demonstrated the impact of peer influence on food intake in adolescents and adults. However, none of these studies focused social modeling effects on food purchases in supermarkets. This study investigated whether the food purchase behavior of a confederate peer would be adopted by the participant. Teenage girls (N=89) were asked to perform a shopping task in a local supermarket. They had to shop with a same-sex confederate peer who had been instructed earlier to purchase either five low-kilocaloric food products, five average-kilocaloric or five high-kilocaloric food products. Significant main effects for the experimental purchase condition and hunger were found on the amount of kilocalories of the purchased food products. Teenage girls who shopped with a peer in the high-kilocaloric condition purchased higher kilocaloric food products relative to the girls who shopped with a peer in the low-kilocaloric condition. In addition, girls who reported to be hungry purchased higher kilocaloric food products in general. These findings might imply that teenage girls follow unhealthy food purchases of a peer during shopping. Health promotion might benefit from our findings by also focusing on food purchases and not only food intake. Copyright © 2011 Elsevier Ltd. All rights reserved.

Representation of a memory fault of a sequential machine M by a function mu on the states of M and the result of the fault by an appropriately determined machine M(mu). Given some sequential behavior B, its inherent tolerance to memory faults can then be measured in terms of the minimum memory redundancy required to realize B with a state-assigned machine having fault tolerance type tau and fault tolerance level t. A behavior having maximum inherent tolerance is exhibited, and it is shown that behaviors of the same size can have different inherent tolerance.

Background Evidence on the effects of restaurant calorie labeling on consumer and restaurant behavior is mixed. This paper examined: 1) consumer responses to calorie information alone or compared to modified calorie information, and 2) changes in restaurant offerings following or in advance of menu labeling implementation. Methods We searched PubMed, Web of Science, Policy File and PAIS International to identify restaurant calorie labeling studies through October 1, 2016, that measured calories ordered, consumed, or available for purchase on restaurant menus. We also searched reference lists of calorie labeling articles. Results Fifty-three studies were included: 18 in real-world restaurants, 9 in cafeterias, and 21 in laboratory or simulation settings. Five examined restaurant offerings. Conclusion Due to a lack of well-powered studies with strong designs, the degree to which menu labeling encourages lower calorie purchases and whether that translates to a healthier population is unclear. Although there is limited evidence that menu labeling affects calories purchased at fast-food restaurants, some evidence demonstrates that it lowers calories purchased at certain types of restaurants and in cafeteria settings. The limited data on modified calorie labels find that such labels can encourage lower-calorie purchases, but may not differ in effects relative to calorie labels alone. PMID:29045080

Objectives Behavioral economic purchase tasks, which estimate demand for drugs, have been successfully developed for cigarettes and are widely used. However, a validated purchase task does not yet exist for e-cigarettes. The aim of this project was to identify the relevant units for an e-cigarette purchase task (E-CPT). Methods Focus groups (N=28 participants in 7 groups, 2-7 participants per group) consisting of current e-cigarette users were conducted. Participants discussed their daily use patterns, completed a preliminary E-CPT which asked how many puffs of their e-cigarette they would consume per day at escalating prices, and discussed the extent to which the task accurately reflected their real-world behavior. Groups were recorded and transcribed; analysis focused on statements related to daily consumption and the E-CPT. Results Participants were unlikely to quantify their daily use in terms of puffs, and perceptions about the appropriate unit for an E-CPT varied across device type. Users of first-generation devices (eg, cigalikes) reported that the relevant unit was the individual device/cartridge; however, participants who purchased nicotine liquid for their device emphasized that e-liquid volume in milliliters would better reflect their use. Conclusions Multiple versions of the E-CPT may be necessary to provide valid measures of e-cigarette demand. PMID:28824938

Do information, price, or morals influence ethical consumption? A natural field experiment and customer survey on the purchase of Fair Trade coffee.

PubMed

Andorfer, Veronika A; Liebe, Ulf

2015-07-01

We address ethical consumption using a natural field experiment on the actual purchase of Fair Trade (FT) coffee in three supermarkets in Germany. Based on a quasi-experimental before-and-after design the effects of three different treatments - information, 20% price reduction, and a moral appeal - are analyzed. Sales data cover actual ethical purchase behavior and avoid problems of social desirability. But they offer only limited insights into the motivations of individual consumers. We therefore complemented the field experiment with a customer survey that allows us to contrast observed (ethical) buying behavior with self-reported FT consumption. Results from the experiment suggest that only the price reduction had the expected positive and statistically significant effect on FT consumption. Copyright © 2015 Elsevier Inc.

The influence of an online auction's product price and e-retailer reputation on consumers' perception, attitude, and behavioral intention.

Wu, Wann-Yih; Huang, Po-Ching; Fu, Chen-Su

2011-06-01

Online auctions combine the conventional auction model with information technology. However, information asymmetry within such auctions causes risks and uncertainties that influence consumer purchase intentions. In this study, a 2 (product price: high vs. low) × 2 (e-retailer reputation: high vs. low) experimental design was used to understand whether the product price and e-retailer reputation will influence consumers' perceived risk, attitude toward the website and purchase intention. The results of this study indicate that perceived risk negatively influences consumer attitude toward the website and online purchase intention, while consumer attitude toward the website positively influences purchase intention. Moreover, involvement moderates the influence of product price and e-retailer reputation only on social risk but does not have a significant effect on consumer attitude toward the website. This study contributes to a more comprehensive understanding of online auction users' behavior. Finally, the managerial implications, limitations and future research directions are also provided. © 2011 The Authors.

Racial and Ethnic Differences in What Smokers Report Paying for Their Cigarettes.

PubMed

Golden, Shelley D; Kong, Amanda Y; Ribisl, Kurt M

2016-07-01

Smoking rates and tobacco-related health problems vary by race and ethnicity. We explore whether cigarette prices, a determinant of tobacco use, differ across racial and ethnic groups, and whether consumer behaviors influence these differences. We used national Tobacco Use Supplement data from 23 299 adult smokers in the United States to calculate average reported cigarette pack prices for six racial and ethnic groups. Using multivariate regression models, we analyzed the independent effect of race and ethnicity on price, and whether these effects changed once indicators of carton purchasing, menthol use, Indian reservation purchase, and state market prices were incorporated. American Indians and whites pay similar amounts and report the lowest prices. Blacks, Hispanics, and Asians reported paying $0.42, $0.68, and $0.89 more for a pack of cigarettes than whites. After accounting for differences in consumer behaviors, these gaps shrunk to $0.27, $0.29, and $0.27, respectively, while American Indians paid $0.38 more than whites. Pack buying was associated with $0.99 higher per-pack prices than carton buying, which was most common among whites. Additionally, people who purchased off an Indian reservation reporting paying $1.54 more than those who purchased on reservation. Average reported cigarette prices vary by race and ethnicity, in part due to differences in product use and purchase location. Tobacco price policies, especially those that target low prices for multipack products or on Indian reservations may increase the prices paid by whites and American Indians, who smoke at the highest rates and pay the least per pack. This study examines differences in reported prices paid by different racial and ethnic groups, using recent, national data from the United States. Results indicating that racial and ethnic groups that smoke at the highest rates (American Indians and whites) also pay the least are consistent with evidence that price is a key factor in cigarette use. Additional analysis finds that cigarette purchasing behaviors, especially carton buying and purchasing on Indian reservations, partially account for the documented price differences, and suggest that policies focused on bulk purchases (carton, multipack) and reservation prices have strong tobacco control potential. © The Author 2016.

Characteristics of parents who purchased kids' meals, reasons for the purchase, and desire for healthy options were examined. Quantitative, cross-sectional study. National. The SummerStyles survey data of 1147 parents (≥18 years). Self-reported outcome variables were purchase of kids' meals (yes/no), reasons for the purchase (13 choices), and desire for healthy options (yes/no). We used multivariable logistic regression to estimate odds ratios (ORs) for purchasing kids' meals based on parental sociodemographic and behavioral characteristics. Over half (51%) of parents reported purchasing kids' meals in the past month. The adjusted OR of purchasing kids' meals were significantly higher among younger parents (OR = 3.44 vs ≥50 years) and among parents who consumed sugar-sweetened beverages (SSBs) daily (OR = 2.70 vs none). No differences were found for race/ethnicity, income, and education. Parents who purchased kids' meals reported that the top 3 reasons for purchase were (1) because their children asked for kids' meals, (2) habit, and (3) offering of healthier sides such as fruits or fruit cups. Thirty-seven percent of parents who did not purchase kids' meals expressed willingness to purchase kids' meals if healthy options were available; this willingness was highest among younger parents (47%; P < .05). Kids' meal purchases were somewhat common. Our findings on characteristics of parents who frequently bought kids' meals (ie, younger parents and SSB consumers), common reasons for purchasing kids' meals, and willingness to buy healthier kids' meal can be used to inform intervention efforts to improve quality of kids' meals.

Older adults purchase and use over-the-counter (OTC) medications with potentially significant adverse effects. Some OTC medications, such as those with anticholinergic effects, are relatively contraindicated for use by older adults due to evidence of impaired cognition and other adverse effects. To inform the design of future OTC medication safety interventions for older adults, this study investigated consumers' decision making and behavior related to OTC medication purchasing and use, with a focus on OTC anticholinergic medications. The study had a cross-sectional design with multiple methods. A total of 84 adults participated in qualitative research interviews (n = 24), in-store shopper observations (n = 39), and laboratory-based simulated OTC shopping tasks (n = 21). Simulated shopping participants also rank-ordered eight factors on their importance for OTC decision making. Findings revealed that many participants had concerns about medication adverse effects, generally, but were not aware of age-related risk associated with the use of anticholinergic medications. Analyses produced a map of the workflow of OTC-related behavior and decision making as well as related barriers such as difficulty locating medications or comparing them to an alternative. Participants reported effectiveness, adverse effects or health risks, and price as most important to their OTC medication purchase and use decisions. A persona analysis identified two types of consumers: the habit follower, who frequently purchased OTC medications and considered them safe; and the deliberator, who was more likely to weigh their options and consider alternatives to OTC medications. A conceptual model of OTC medication purchase and use is presented. Drawing on study findings and behavioral theories, the model depicts dual processes for OTC medication decision making - habit-based and deliberation-based - as well as the antecedents and consequences of decision making. This model suggests several design directions for consumer-oriented interventions to promote OTC medication safety. Copyright © 2018 Elsevier Inc. All rights reserved.

Choosing healthier foods in recreational sports settings: a mixed methods investigation of the impact of nudging and an economic incentive

PubMed Central

2014-01-01

Background Nudging is an approach to environmental change that alters social and physical environments to shift behaviors in positive, self-interested directions. Evidence indicates that eating is largely an automatic behavior governed by environmental cues, suggesting that it might be possible to nudge healthier dietary behaviors. This study assessed the comparative and additive efficacy of two nudges and an economic incentive in supporting healthy food purchases by patrons at a recreational swimming pool. Methods An initial pre-intervention period was followed by three successive and additive interventions that promoted sales of healthy items through: signage, taste testing, and 30% price reductions; concluding with a return to baseline conditions. Each period was 8 days in length. The primary outcome was the change in the proportion of healthy items sold in the intervention periods relative to pre- and post-intervention in the full sample, and in a subsample of patrons whose purchases were directly observed. Secondary outcomes included change in the caloric value of purchases, change in revenues and gross profits, and qualitative process observations. Data were analyzed using analysis of covariance, chi-square tests and thematic content analysis. Results Healthy items represented 41% of sales and were significantly lower than sales of unhealthy items (p < 0.0001). In the full sample, sales of healthy items did not differ across periods, whereas in the subsample, sales of healthy items increased by 30% when a signage + taste testing intervention was implemented (p < 0.01). This increase was maintained when prices of healthy items were reduced by 30%, and when all interventions were removed. When adults were alone they purchased more healthy items compared to when children were present during food purchases (p < 0.001), however parental choices were not substantially better than choices made by children alone. Conclusions This study found mixed evidence for the efficacy of nudging in cueing healthier dietary behaviors. Moreover, price reductions appeared ineffectual in this setting. Our findings point to complex, context-specific patterns of effectiveness and suggest that nudging should not supplant the use of other strategies that have proven to promote healthier dietary behaviors.

Humanizing machines: Anthropomorphization of slot machines increases gambling.

PubMed

Riva, Paolo; Sacchi, Simona; Brambilla, Marco

2015-12-01

Do people gamble more on slot machines if they think that they are playing against humanlike minds rather than mathematical algorithms? Research has shown that people have a strong cognitive tendency to imbue humanlike mental states to nonhuman entities (i.e., anthropomorphism). The present research tested whether anthropomorphizing slot machines would increase gambling. Four studies manipulated slot machine anthropomorphization and found that exposing people to an anthropomorphized description of a slot machine increased gambling behavior and reduced gambling outcomes. Such findings emerged using tasks that focused on gambling behavior (Studies 1 to 3) as well as in experimental paradigms that included gambling outcomes (Studies 2 to 4). We found that gambling outcomes decrease because participants primed with the anthropomorphic slot machine gambled more (Study 4). Furthermore, we found that high-arousal positive emotions (e.g., feeling excited) played a role in the effect of anthropomorphism on gambling behavior (Studies 3 and 4). Our research indicates that the psychological process of gambling-machine anthropomorphism can be advantageous for the gaming industry; however, this may come at great expense for gamblers' (and their families') economic resources and psychological well-being.

The substitutability of cigarettes and food: A behavioral economic comparison in normal weight and overweight or obese smokers.

Obesity and cigarette smoking contribute to a multitude of preventable deaths in the United States and eating and smoking behavior may influence each other. The field of behavioral economics integrates principles from psychology and economics and permits systematic examination of how commodities interrelate with one another. Using this framework, the current study evaluated the effects of rising food and cigarette prices on consumption to investigate their substitutability and their relationship to BMI and associated variables. Behavioral economics categorizes commodities as substitutable when the consumption of one increases as a function of a price increase in the other. Smokers (N = 86) completed a 2-part hypothetical task in which money was allocated to purchase cigarettes and fast-food-style reinforcers (e.g., hamburgers, ice cream) at various prices. Results indicated that food and cigarettes were not substitutes for one another (cross-price elasticity coefficients < .20). Food purchases were independent of cigarette price, whereas cigarette purchases decreased as food price rose. Cross-price elasticity coefficients were significantly associated with confidence in one's ability to control weight without smoking (rs = -.23 and .29), but not BMI (rs = .04 and .04) or postcessation weight concerns (rs = -.05 and .12). Perceived ability to manage weight without cigarettes may influence who substitutes food for cigarettes when quitting. In addition, given observed decreases in purchases of both commodities as food prices increased, these findings imply that greater taxation of fast-food-style reinforcers could potentially reduce consumption of these foods and also cigarettes among smokers.

To measure impact of information, education, and communication intervention (IEC) on rational medicine use, purchase, and stocking behavior. This was a pre- and post-design, interventional study. Base data were collected in first visit, using pre tested questionnaire from 500 respondents, who were of either gender, English speaking, at least graduates, permanent residents, and willing to participate. IEC was framed based on problems identified from this data. First intervention was handouts distributed in the second visit, containing information on cost saving in medicine purchase. Second intervention was a lecture session on medicine prices, rational use of medicines, and tips on saving on medicine purchase. Five articles about medicine use and price differences were published in the local newspaper, over 10 days, formed third intervention. After 1 month, post-intervention data was collected using same instrument with some additional questions. Results were analyzed by Chi-square test using Graph Pad prism Version 3.0. Awareness about price variation, self-medication, expiry period, generic and brand quality increased post-intervention. Attitudes toward new, costly, brands, injections, sharing and reusing old prescriptions changed post-intervention. Behavioral changes in stocking habits, adherence to doctors' advice, getting cash memo, comparing prices, reading labels, were seen post-intervention. People carry false notions about medicines which influence their use and habits. This intervention successfully changed behavior and could bring awareness on many aspects of medicine use.

Most young adults do not consume recommended levels of fruits and vegetables (FV), and interventions to increase FV-related behaviors among this understudied population are needed. Therefore, it is important to identify correlates of FV intake among young adults to guide intervention development. This cross-sectional study utilized data from an online survey to identify factors related to young adults’ FV purchasing, preparation, and consumption, and to explore between-factor relationships using mediation analysis. In 2010, 1201 college students in Minnesota completed questionnaires assessing FV behaviors, as well as perceptions of FV-related individual, social, and environmental factors. Factor analysis identified questionnaire items assessing similar constructs. Seven factors were identified (personal barriers, FV knowledge, family, friends, neighborhood, access barriers, and campus) and evaluated for relationships with FV purchasing, preparation, and consumption using linear regression. Results revealed that perceived personal barriers (e.g., lacking cooking skills) were inversely related to all FV outcomes. Perception that family and friends eat healthfully and neighborhood access to FV were positively related to all outcomes. Individual-, social-, and environmental-level perceptions were related to purchasing, preparation, and consumption, and the effects of these factors were similar when accounting for mediated effects. Factors at all three levels and the ways in which these various factors operate together may be important to consider in future efforts to improve FV behaviors among young adults. PMID:23958116

Objective This paper examines trends in cigarette prices and corresponding purchasing patterns over a 9 year period and explores characteristics associated with the quantity and location of cigarettes purchased by adult smokers in the United States. Methods The data for this paper come from a nationally representative longitudinal survey of 6,669 adult smokers (18 years and older) who were recruited and surveyed between 2002 and 2011. Telephone interviews were conducted annually, and smokers were asked a series of questions about the location, quantity (i.e., single vs. multiple packs or cartons), and price paid for their most recent cigarette purchase. Generalized estimating equations were used to assess trends and model characteristics associated with cigarette purchasing behaviors. Results Between 2002 and 2011, the reported purchase of cigarette cartons and the use of coupons declined while multi-pack purchases increased. Compared with those purchasing by single packs, those who purchased by multi-packs and cartons saved an average of $0.53 and $1.63, respectively. Purchases in grocery and discount stores declined, while purchases in tobacco only outlets increased slightly. Female, older, white smokers were more likely to purchase cigarettes by the carton or in multi-packs and in locations commonly associated with tax avoidance (i.e., duty free shops, Indian reservations). Conclusions As cigarette prices have risen, smokers have begun purchasing via multi-packs instead of cartons. As carton sales have declined, purchases from grocery and discount stores have also declined, while an increasing number of smokers report low tax sources as their usual purchase location for cigarettes.

Libraries are an inherently sedentary environment, but are an understudied setting for sedentary behavior interventions. To investigate the feasibility of incorporating portable pedal machines in a university library to reduce sedentary behaviors. The 11-week intervention targeted students at a university library. Thirteen portable pedal machines were placed in the library. Four forms of prompts (e-mail, library website, advertisement monitors, and poster) encouraging pedal machine use were employed during the first 4 weeks. Pedal machine use was measured via automatic timers on each machine and momentary time sampling. Daily library visits were measured using a gate counter. Individualized data were measured by survey. Data were collected in fall 2012 and analyzed in 2013. Mean (SD) cumulative pedal time per day was 95.5 (66.1) minutes. One or more pedal machines were observed being used 15% of the time (N=589). Pedal machines were used at least once by 7% of students (n=527). Controlled for gate count, no linear change of pedal machine use across days was found (b=-0.1 minutes, p=0.75) and the presence of the prompts did not change daily pedal time (p=0.63). Seven of eight items that assessed attitudes toward the intervention supported intervention feasibility (p<0.05). The unique non-individualized approach of retrofitting a library with pedal machines to reduce sedentary behavior seems feasible, but improvement of its effectiveness is needed. This study could inform future studies aimed at reshaping traditionally sedentary settings to improve public health. Copyright © 2014 American Journal of Preventive Medicine.

Objectives. We examined the relationship between cigarette excise tax increases and tax-avoidant purchasing behaviors among New York City adult smokers. Methods. We analyzed data from the city’s annual Community Health Survey to assess changes in rates of tax avoidance over time (2003–2010) and smokers’ responses to the 2008 state cigarette tax increase. Multivariable logistic regression analysis identified correlates of buying more cigarettes on the street in response to the increase. Results. After the 2002 tax increase, the percentage of smokers engaged in tax-avoidant behavior decreased with time from 30% in 2003 to 13% in 2007. Following the 2008 tax increase, 21% of smokers reported buying more cigarettes from another person on the street. Low-income, younger, Black, and Hispanic smokers were more likely than respondents with other sociodemographic characteristics to purchase more cigarettes on the street. Conclusions. To maximize public health impact, cigarette tax increases should be paired with efforts to limit the flow of untaxed cigarettes entering jurisdictions with high cigarette pack prices. PMID:23597382

Place over traits? Purchasing edibles from medical marijuana dispensaries in Los Angeles, CA.

PubMed

Kepple, Nancy Jo; Freisthler, Bridget

2017-10-01

To examine discrete purchasing behaviors of marijuana-infused edibles from medical marijuana dispensaries with the aim to identify potential venue- and individual-level targets for prevention. Two-stage, venue-based sampling approach was used to randomly select patrons exiting 16 medical marijuana dispensaries in Los Angeles, California during Spring 2013. Hierarchical generalized linear modeling was used to examine the likelihood of purchasing edibles among 524 patrons reporting a discrete purchase regressed on characteristics of the sampled dispensaries and their patrons. At a venue level, patrons were more likely to purchase edibles from dispensaries located within Census tracts with higher median incomes or in close proximity to a higher number of dispensaries. At an individual level, patrons who identified as Black or Hispanic were associated with a lower likelihood of purchasing edibles when compared to patrons who identified as other non-White, non-Hispanic race/ethnicity. Place-based policies focused on regulating edible sales through dispensaries may be fruitful in influencing access to edibles. Additionally, social marketing campaigns may benefit from targeting both locations where edible purchases are more likely and populations who are more likely to purchase edibles.

My friends have a word for it: Event-related potentials evidence of how social risk inhibits purchase intention.

PubMed

2017-03-16

Social risk refers to the potential disapproval from significant others (especially family or friends), and it is crucial in dissuading consumers from making decisions to purchase. The current study explored the neural process underlying how social risk influenced people's purchase intention. Event-related potentials (ERPs) were employed to investigate the electrophysiological process when subjects evaluated their purchase intention for products with social risk factors. The behavioral data showed that the social risk condition inhibited people's purchase intention compared to the control condition. Neurophysiologically, larger anterior N2 amplitude was induced by the social risk condition in contrast with the control condition. We suggest that this anterior N2 may reflect the cognitive control or conflict monitoring. It may be that the participant has to regulate the conflict between an internal desire to purchase the item and the discordant information obtained from the social risk sentence, which would pressure the participant to not purchase the item in accord with social norms. These findings will be helpful in understanding the neural basis of social risk perception during purchase decisions. Copyright © 2017 Elsevier B.V. All rights reserved.

To examine purchase patterns at fast-food restaurants and their relation to restaurant characteristics, customer characteristics, and use of calorie information. Cross-sectional survey. Fast-food restaurants in New York State. Adult fast-food restaurant customers (n = 1,094). Restaurant characteristics (fast-food chain type, presence of calorie labels, and poverty of location), participant characteristics (demographics, calorie knowledge, awareness, and use), and customer purchasing patterns (ordering low-calorie or no beverage, small or no fries, or < 3 items) were used as predictors of total calories purchased. Multiple regression. In a regression model including restaurant and customer characteristics, fast-food chain customer age, sex, calorie use, and calorie awareness were independently associated with total calories purchased (all P < .05; model R2 = .19). When 3 purchasing patterns were added to the model, calorie use (P = .005), but not calorie awareness, remained associated with total calories purchased. The 3 purchase patterns collectively accounted for the majority of variance in calorie totals (Δ model R2 = .40). Promoting use of calorie information, purchase strategies, and calorie awareness represents complementary ways to support lower-calorie choices at fast-food chains.

2013-10-01

To assess whether adolescents purchasing food at a restaurant marketed as "healthy" (Subway) purchase fewer calories than at a competing chain (McDonald's). We studied 97 adolescents who purchased a meal at both restaurants on different days, using each participant as his or her control. We compared the difference in calories purchased by adolescents at McDonald's and Subway in a diverse area of Los Angeles, CA. Adolescents purchased an average of 1,038 calories (standard error of the mean [SEM]: 41) at McDonald's and 955 calories (SEM 39) at Subway. The difference of 83 calories (95% confidence interval [CI]: -20 to 186) was not statistically significant (p = .11). At McDonald's, participants purchased significantly more calories from drinks (151 vs. 61, p < .01) and from side dishes (i.e., French fries or potato chips; 201 at McDonald's vs. 35 at Subway, p < .01). In contrast, they purchased fewer cups of vegetables at McDonald's (.15 vs. .57 cups, p < .01). We found that, despite being marketed as "healthy," adolescents purchasing a meal at Subway order just as many calories as at McDonald's. Although Subway meals had more vegetables, meals from both restaurants are likely to contribute to overeating. Copyright © 2013 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

Brodny, Jarosław; Tutak, Magdalena

2018-01-01

Determination of effective use of mining devices has very significant meaning for mining enterprises. High costs of their purchase and tenancy cause that these enterprises tend to the best use of possessed technical potential. However, specifics of mining production causes that this process not always proceeds without interferences. Practical experiences show that determination of objective measure of utilization of machine in mining enterprise is not simple. In the paper a proposition for solution of this problem is presented. For this purpose an IT platform and overall efficiency model OEE were used. This model enables to evaluate the machine in a range of its availability performance and quality of product, and constitutes a quantitative tool of TPM strategy. Adapted to the specificity of mining branch the OEE model together with acquired data from industrial automatic system enabled to determine the partial indicators and overall efficiency of tested machines. Studies were performed for a set of machines directly use in coal exploitation process. They were: longwall-shearer and armoured face conveyor, and beam stage loader. Obtained results clearly indicate that degree of use of machines by mining enterprises are unsatisfactory. Use of IT platforms will significantly facilitate the process of registration, archiving and analytical processing of the acquired data. In the paper there is presented methodology of determination of partial indices and total OEE together with a practical example of its application for investigated machines set. Also IT platform was characterized for its construction, function and application.

A composite likelihood approach for spatially correlated survival data

2013-01-01

The aim of this paper is to provide a composite likelihood approach to handle spatially correlated survival data using pairwise joint distributions. With e-commerce data, a recent question of interest in marketing research has been to describe spatially clustered purchasing behavior and to assess whether geographic distance is the appropriate metric to describe purchasing dependence. We present a model for the dependence structure of time-to-event data subject to spatial dependence to characterize purchasing behavior from the motivating example from e-commerce data. We assume the Farlie-Gumbel-Morgenstern (FGM) distribution and then model the dependence parameter as a function of geographic and demographic pairwise distances. For estimation of the dependence parameters, we present pairwise composite likelihood equations. We prove that the resulting estimators exhibit key properties of consistency and asymptotic normality under certain regularity conditions in the increasing-domain framework of spatial asymptotic theory.

Advertising, marketing and purchase behavior for energy-related products

DOE Office of Scientific and Technical Information (OSTI.GOV)

Tiedemann, K.; Nelson, D.

Energy conservation programs have relied heavily on incentives and regulatory standards to reduce residential energy consumption. However, in the changing market environment characterized by competitive pressures, alternative mechanisms such as marketing and promotions may increase substantially in importance compared to the demand-side management programs which have been the focus of most research. This paper describes the role of marketing and promotions in encouraging energy efficiency at the household level in British Columbia. The paper examines three related issues: first, the purchase process for energy-related products; second, the criteria used by customers in making purchase decisions; and third, the impact andmore » effectiveness of alternative marketing tools. A key finding is the energy-related purchases do not fall into the impulse purchase category. There are two reasons for this: first, most of these products require installation and this requires a high level of commitment on the part of the purchaser; second, many energy-related products require a significant outlay of funds and this reduces impulse buying.« less

Influence of Price and Labeling on Energy Drink Purchasing in an Experimental Convenience Store.

Temple, Jennifer L; Ziegler, Amanda M; Epstein, Leonard H

2016-01-01

To examine the impact of energy drink (ED) pricing and labeling on the purchase of EDs. Participants visited a laboratory-based convenience store 3 times and purchased a beverage under different ED labeling (none, caffeine content, and warning labels) and pricing conditions. The 36 participants (aged 15-30 years) were classified as energy drink consumers (≥ 2 energy drinks/wk) and nonconsumers (< 1 energy drink/mo). Data were log transformed to generate elasticity coefficients. The authors analyzed changes in elasticity as a function of price and labeling using mixed-effects regression models. Increasing the price of EDs reduced ED purchases and increased purchasing of other caffeinated beverages among ED consumers. Energy drink labels affected ED sales in adolescents. These data suggest that ED pricing and labeling may influence the purchasing of ED, especially in adolescent consumers. Copyright © 2016 Society for Nutrition Education and Behavior.

1992-11-01

This article examines factors that predict changes in consumer purchasing decisions of nonprescription medications. Variables corresponding to factors in Andersen's behavioral model are measured, in addition to data regarding characteristics of the 17 pharmacy consultants who provided counseling services. One thousand seven hundred and thirteen consumers in five stores in southern California were provided consultation during a 6-month period, resulting in 25.4% of the patients purchasing a different drug than intended when entering the pharmacy, 1.3% being referred to a physician, and 13.4% not purchasing any over-the-counter medication at all. Logistic regression techniques demonstrated that one enabling variable (availability of generic medications), and four need factors (the discussion of clinical issues, short encounters, cough and cold products, and vitamin products) were significant predictors of the consumer's decision to purchase a different product than intended. Consultant characteristics (introversion, external locus of control) were also important predictors, but opposite the expected direction. Consumers who received information from female consultants were more likely to change their purchasing decisions.

Experimental research on the relation between food price changes and food-purchasing patterns: a targeted review.

One way in which to modify food purchases is to change prices through tax policy, subsidy policy, or both. We reviewed the growing body of experimental research conducted in the laboratory and in the field that investigates the following: the extent to which price changes influence purchases of targeted and nontargeted foods, total energy, or macronutrients purchased; the interaction of price changes with adjunctive interventions; and moderators of sensitivity to price changes. After a brief overview of economic principles and observational research that addresses these issues, we present a targeted review of experimental research. Experimental research suggests that price changes modify purchases of targeted foods, but research on the overall nutritional quality of purchases is mixed because of substitution effects. There is mixed support for combining price changes with adjunctive interventions, and there are no replicated findings on moderators to price sensitivity in experiments. Additional focused research is needed to better inform food policy development with the aim of improving eating behavior and preventing obesity.

To explore the role of feeding practices and food purchases in toddler dietary intake and anthropometry. A convenience sample of Latino mother and toddler pairs were interviewed at baseline and at 6-month follow-up. Data on feeding practices, toddler dietary intake, anthropometry, and food purchases were collected using the Toddler-Feeding Questionnaire; 24-hour recalls; measurements of weight, height, and/or length; and food purchase receipts. Indulgent feeding scores and high intake of sweetened beverage were associated with a 0.52 increase (P = .03) and 0.46 increase in toddler weight-for-height z-score (P = .05), respectively. Households with 10 percentage points of more sweetened food and beverage expenditures were associated with increases in weight indicator z-scores. Indulgent feeding, high intake, and purchase of sweetened beverage are associated with weight gain in Latino toddlers. Programs should target food purchasing decisions and provide concrete guidance for the division of responsibility around feeding. Copyright © 2014 Society for Nutrition Education and Behavior.

[The price-based certainty of purchase influences consumer behavior for discount].

Arihara, Katsuhiko; Ariga, Atsunori; Furuya, Takeshi

2016-04-01

Tversky & Kahneman (1981) reported that most participants decided to drive when they could save money on a low-price good as compared to when they could save on a high-price good, even though the discount prices were same. Although this irrational decision making has been interpreted as a rate-dependent estimation of value (prospect theory), this study newly proposes that it can be explained by the certainty of purchase based on the price of goods. Experiment 1 replicated the previously reported difference in decision making, and additionally demonstrated that participants' certainty of purchase was lower for a high- than a low-price good. When it was emphasized that participants' intention to purchase high- and low-price goods were equally sure, decision making did not significantly differ (Experiment 2). Furthermore, decision making differed based only on the certainty of purchase even,when prices of goods were-same (Experiment 3). Consumers' decision making may be rather rational, depending straightforwardly on the certainty of purchase that is susceptible to price.

To study the effects of school lessons about healthy food on adolescents' self-reported beliefs and behaviour regarding the purchase and consumption of soft drinks, water and extra foods, including sweets and snacks. The lessons were combined with the introduction of lower-calorie foods, food labelling and price reductions in school vending machines. A cluster-randomized controlled design was used to allocate schools to an experimental group (i.e. lessons and changes to school vending machines) and a control group (i.e. 'care as usual'). Questionnaires were used pre-test and post-test to assess students' self-reported purchase of extra products and their knowledge and beliefs regarding the consumption of low-calorie products. Secondary schools in the Netherlands. Twelve schools participated in the experimental group (303 students) and fourteen in the control group (311 students). The students' mean age was 13.6 years, 71.5% were of native Dutch origin and mean BMI was 18.9 kg/m(2). At post-test, the experimental group knew significantly more about healthy food than the control group. Fewer students in the experimental group (43%) than in the control group (56%) reported bringing soft drinks from home. There was no significant effect on attitude, social norm, perceived behavioural control and intention regarding the consumption of low-calorie extra products. The intervention had limited effects on students' knowledge and self-reported behaviour, and no effect on their beliefs regarding low-calorie beverages, sweets or snacks. We recommend a combined educational and environmental intervention of longer duration and engaging parents. More research into the effects of such interventions is needed.

Indoor tanning remains a popular activity in Western cultures despite a growing body of literature suggesting its link to skin cancer and melanoma. Advances in indoor tanning research have illuminated problematic patterns of its use. With problems such as difficulty quitting, devoting resources toward its use at the expense of healthy activities, and excessive motivation and urges to tan, symptoms of excessive indoor tanning appear consistent with behavioral addiction. The present study bridges the gap between clinical approaches to understanding indoor tanning problems and behavioral economic considerations of unhealthy habits and addiction. Eighty undergraduate females completed both the Behavioral Addiction Indoor Tanning Screener and the Tanning Purchase Task. Results suggest that behavioral economic demand for tanning significantly differs between risk classification groups, providing divergent validity to the Behavioral Addiction Indoor Tanning Screener and offering additional evidence of the sensitivity of the Tanning Purchase Task to differentiating groups according to tanning profiles.

The effect of life-cycle cost disclosure on consumer behavior

NASA Astrophysics Data System (ADS)

Deutsch, Matthias

For more than 20 years, analysts have reported on the so-called "energy paradox" or the "energy efficiency gap", referring to the fact that economic agents could in principle lower their total cost at current prices by using more energy-efficient technology but, nevertheless, often decide not to do so. Theory suggests that providing information in a simplified way could potentially reduce this "efficiency gap". Such simplification may be achieved by providing the estimated monetary operating cost and life-cycle cost (LCC) of a given appliance---which has been a recurring theme within the energy policy and efficiency labeling community. Yet, little is known so far about the causal effects of LCC disclosure on consumer action because of the gap between the acquisition of efficiency information and consumer purchasing behavior in the real marketplace. This dissertation bridges the gap by experimentally integrating LCC disclosure into two major German commercial websites---a price comparison engine for cooling appliances, and an online shop for washing machines. Internet users arriving on these websites were randomly assigned to two experimental groups, and the groups were exposed to different visual stimuli. The control group received regular product price information, whereas the treatment group was, in addition, offered information about operating cost and total LCC. Click-stream data of consumers' shopping behavior was evaluated with multiple regression analysis by controlling for several product characteristics. This dissertation finds that LCC disclosure reduces the mean energy use of chosen cooling appliances by 2.5% (p<0.01), and the energy use of chosen washing machines by 0.8% (p<0.001). For the latter, it also reduces the mean water use by 0.7% (p<0.05). These effects suggest a potential role for public policy in promoting LCC disclosure. While I do not attempt to estimate the costs of such a policy, a simple quantification shows that the benefits amount to 100 to 200 thousand Euros per year for Germany, given current predictions regarding the price of tradable permits for CO2, and not counting other potential benefits. Future research should strive for increasing external validity, using better instruments, and evaluating the effectiveness of different information formats for LCC disclosure.

Effect of co-payment on behavioral response to consumer genomic testing.

2018-01-29

Existing research in consumer behavior suggests that perceptions and usage of a product post-purchase depends, in part, on how the product was marketed, including price paid. In the current study, we examine the effect of providing an out-of-pocket co-payment for consumer genomic testing (CGT) on consumer post-purchase behavior using both correlational field evidence and a hypothetical online experiment. Participants were enrolled in a longitudinal cohort study of the impact of CGT and completed behavioral assessments before and after receipt of CGT results. Most participants provided a co-payment for the test (N = 1668), while others (N = 369) received fully subsidized testing. The two groups were compared regarding changes in health behaviors and post-test use of health care resources. Participants who paid were more likely to share results with their physician (p = .012) and obtain follow-up health screenings (p = .005) relative to those who received fully subsidized testing. A follow-up online experiment in which participants (N = 303) were randomized to a "fully-subsidized" versus "co-payment" condition found that simulating provision of a co-payment significantly increased intentions to seek follow-up screening tests (p = .050) and perceptions of the test results as more trustworthy (p = .02). Provision of an out-of-pocket co-payment for CGT may influence consumer's post-purchase behavior consistent with a price placebo effect. Cognitive dissonance or sunk cost may help explain the increase in screening propensity among paying consumers. Such individuals may obtain follow-up screenings to validate their initial decision to expend personal resources to obtain CGT. © Society of Behavioral Medicine 2018.

2010-01-01

The Healthy Vending Machine Pilot Project (HVMPP) was a public health initiative intended to create a healthier school nutrition environment by making healthier snacks available in vending machines, while maintaining a profit margin. The HVMPP was evaluated using quantitative and qualitative measures. Vending machines were stocked with healthier choices and conventional vending products at a 50:50 ratio. The HVMPP was implemented from February to May 2007 in four Ontario secondary schools in Middlesex-London, Elgin, and Oxford counties. Product sales were tracked, and focus groups were conducted to obtain students' opinions about healthy eating and vending choices. "Healthier choice" sales ranged from 14% to 17%. In all schools, vending revenues declined from 0.7% to 66%. A majority of participants had substantial knowledge of healthy eating and were in favour of healthier choices in vending machines; however, price, value, and taste were barriers that led them to purchase these products rarely. Students preferred to have "real" healthy snacks, such as yogurt, fruit, and vegetables, available in schools. Replacing 50% of vending stock with healthier snacks resulted in a decline in vending revenues. Future health programs in schools need to provide "real" healthy snacks, such as low-fat dairy products, fruits, and vegetables.

Dispositional Employability and Online Training Purchase. Evidence from Employees' Behavior in Spain.

This article explores the relationship between dispositional employability and online training purchase. Through a sample of 883 employees working for enterprises in Spain, and a using principal component analysis and binomial logit probabilistic models, the research revealed two main results. First, it was found that dispositional employability is characterized by five factors: "openness to changes at work," "career motivation and work resilience," "work and career proactivity," "optimism and engagement at work," and "work identity." Second, the research also found a double causality in the relationship analysis between dispositional employability and online training purchase. However, this causality is not direct. In explaining dispositional employability, certain motivations and types of behavior of employees participating in online training are significant. In particular, greater sensitivity toward career-related personal empowerment, a greater predisposition toward developing new experiences at work, and a greater awareness of the fact that positive job outcomes are related to preparation conscientiousness. In explaining online training purchase, employees who are more motivated and who better identify with their jobs are more likely to pay. Moreover, employees who spend more time on training and have less contact with new trends in their jobs, find it hard to keep calm in difficult situations, and have a greater predisposition toward effort, and preference for novelty, variety and challenges at work are more likely to purchase online training.

To examine the agreement between perceptions, behaviors, and ability to purchase healthful food in the Lower Mississippi Delta (LMD). A regional food store survey of healthful food options in supermarkets, small/medium stores, and convenience stores. Focus group discussions were conducted on shopping perceptions and behaviors. Counties in Arkansas, Louisiana, and Mississippi. Eighty-one LMD residents, 18-60+ years of age. Perceptions of healthful food and ability to acquire these food items across store types. Focus group data were analyzed using thematic coding. Summary food store statistics were weighted, and estimates were constructed using SUDAAN 9. Data triangulation was achieved by comparing focus group findings with food availability data. A majority (> 85%) of supermarkets had selected vegetables, breads, and cereals perceived as healthful, whereas availability was limited in small to medium grocery stores and convenience stores. Skim milk, perceived as healthful, was limited in all store types. Limited availability and perceived costs of healthful food in the LMD influenced purchasing behaviors. Attitudes and perceptions should be incorporated into intervention development to improve food choices in conjunction with increasing the availability of healthful food in the LMD.

Intention to purchase organic food among young consumers: Evidences from a developing nation.

PubMed

Yadav, Rambalak; Pathak, Govind Swaroop

2016-01-01

The present study attempts to investigate the consumer's intention to purchase organic food in the context of a developing nation (India) using the Theory of Planned Behavior (TPB). Further, the study has incorporated additional constructs (moral attitude, health consciousness and environmental concern) in the TPB and measured its appropriateness. Responses were collected from 220 young consumers adopting convenience sampling approach. Data were analyzed using Structural Equation Modeling (SEM) to evaluate the strength of relationship between the constructs. The findings reported that the TPB partially supported the organic food purchase intention. Among the additional constructs incorporated, moral attitude and health consciousness positively influenced the consumer's intention to purchase organic food. The study has supported the inclusion of new constructs in the TPB as it has improved the predictive power of the proposed framework in determining consumer's intention to purchase organic food.

Household-level Canadian meat purchases from 2002 to 2008 and a Food Opinions Survey conducted in 2008 were used to explore consumer responses to bovine spongiform encephalopathy (BSE) at the national level in Canada. Consumption in terms of the number of unit purchases was analyzed with a random-effects negative binomial model. In this study, household heterogeneity in meat purchases was partially explained using data from a self-reported food opinions survey. Of special interest was the hypothesis that consumers responded consistently to BSE in a one-time survey and in actual meat purchase behavior spanning years. Regional differences appeared, with consumers in eastern Canada reacting most negatively to BSE. Consumers responded more to the perception that food decision makers are honest about food safety than to the perception that they are knowledgeable, in maintaining beef purchases during BSE events.

Individuals with inefficient executive (higher level cognitive) function have a reduced ability to resist dietary temptation. The present study aimed to design and test a theory-based point-of-purchase intervention for coffee shops that reduced the calorie content of customers' purchases by reducing the need for executive function (EF) at the moment of choice. Key facets of EF were identified by a multidisciplinary group and used to develop a point-of-purchase intervention (signage). This intervention was evaluated in a randomized controlled trial (RCT) in a public coffee shop on consumer purchases of >20,000 snacks and drinks over 12 weeks. A sample of customers (n = 128) was recruited to complete an embedded cross-sectional study measuring EF strength, dietary intentions, typical purchases, and purchases made after exposure to the intervention. The proportion of snack purchases that were high in calorie reduced significantly (t(10) = 2.34, p = .04) in intervention weeks relative to control. High calorie drink purchases were also lower in intervention than control weeks, however, this difference was not significant (t(10) = 1.56, p = .15). On average, customers purchased items containing 66 calories < usual after exposure to the intervention. The magnitude of the intervention's positive effect on customer behavior increased as EF strength decreased (β = .24, p = .03). The calorie content of cafe purchases can be lowered by reducing the cognitive demands of healthy food choice at the moment of purchase, especially in those with poor EF. Environmental changes like these have the potential to help achieve population weight control. (c) 2015 APA, all rights reserved.

Behavioral interventions show potential for promoting increased fruit and vegetable consumption in the general population. However, little is known about their effectiveness or cost-effectiveness among socioeconomically disadvantaged groups, who are less likely to consume adequate fruit and vegetables. This study investigated the effects and costs of a behavior change intervention for increasing fruit and vegetable purchasing and consumption among socioeconomically disadvantaged women. ShopSmart 4 Health was a randomized controlled trial involving a 3-mo retrospective baseline data collection phase [time (T) 0], a 6-mo intervention (T1-T2), and a 6-mo no-intervention follow-up (T3). Socioeconomically disadvantaged women who were primary household shoppers in Melbourne, Australia, were randomly assigned to either a behavior change intervention arm (n = 124) or a control arm (n = 124). Supermarket transaction (sales) data and surveys measured the main outcomes: fruit and vegetable purchases and self-reported fruit and vegetable consumption. An analysis of supermarket transaction data showed no significant intervention effects on vegetable or fruit purchasing at T2 or T3. Participants in the behavior change intervention arm reported consumption of significantly more vegetables during the intervention (T2) than did controls, with smaller intervention effects sustained at 6 mo postintervention (T3). Relative to controls, vegetable consumption increased by ∼0.5 serving · participant(-1) · d(-1) from baseline to T2 and remained 0.28 servings/d higher than baseline at T3 among those who received the intervention. There was no intervention effect on reported fruit consumption. The behavior change intervention cost A$3.10 (in Australian dollars) · increased serving of vegetables(-1) · d(-1)CONCLUSIONS: This behavioral intervention increased vegetable consumption among socioeconomically disadvantaged women. However, the lack of observed effects on fruit consumption and on both fruit and vegetable purchasing at intervention stores suggests that further investigation of effective nutrition promotion approaches for this key target group is required.

Laugesen, M; Scragg, R

1999-10-08

To determine recent changes in cigarette purchasing behaviour of 14- and 15-year-old students in New Zealand. Nationwide cross-sectional surveys of fourth form students in 85 schools in New Zealand by means of an anonymous self-administered questionnaire collected in November 1992 and in November 1997. Analyses were restricted to 4198 out of 11 824 total students in 1992, and 4526 out of a total of 11 350 in 1997, who were current smokers aged 14 and 15 years. Self-purchasing of cigarettes decreased by 37% (95% CI: -40, -34) from 1992 to 1997, adjusting for age, sex and ethnicity, while acquiring cigarettes from other people increased. There was decreased purchasing from dairies (-6%; 95% CI: -8, -4) and supermarkets (-9%; 95% CI: -16, -1) but increases from other sources such as take-away shops, tobacconists and vending machines. From 1992 to 1997, weekly buying increased by 23% (95% CI 16, 32), students who were refused a sale increased by 153% (95% CI 139, 169) and students who had difficulty in buying increased by 324% (95% CI 276, 379). The latter were less likely to buy weekly than students who did not have difficulty (31.1% vs 41.4%). Students who smoked < or =5 cigarettes per week were 32% (95% CI 13, 53) more likely to have difficulty in buying than students smoking >20 per week. These results indicate major changes in cigarette purchasing behaviour between 1992 and 1997, when there was increased enforcement against underage sales of tobacco.

2006-10-01

A recent study of arrest data show that African Americans are 2.5 times more likely to be arrested for marijuana possession offences than Whites, even though general prevalence estimates show that they are no more likely to be using. The current study investigates the purchase patterns of marijuana users from the 2002 National Survey on Drug Use and Health (NSDUH) to evaluate whether differences in purchasing behaviors exist across racial groups. Although in general people who purchase marijuana are more likely to buy in private settings and from someone they know, this analysis shows that African Americans are statistically more likely to engage in risky purchasing behaviors that increase their likelihood of arrest. Using trivariate probit regression with demographic, drug use, and drug market covariates, analyses reveal that African Americans are nearly twice as likely to buy outdoors (0.31 versus 0.14), three times more likely to buy from a stranger (0.30 versus 0.09), and significantly more likely to buy away from their homes (0.61 versus 0.48). These results provide an additional explanation for the differential in arrest rates between African Americans and Whites.

Over the past several decades, the economic damage from flooding in the coastal areas has greatly increased due to rapid coastal development coupled with possible climate change impacts. One effective way to mitigate excessive economic losses from flooding is to purchase flood insurance. Only a minority of coastal residents however have taken this preventive measure. Using original survey data for all coastal counties of the United States Gulf Coast merged with contextual data, this study examines the effects of external influences and perceptions of flood-related risks on individuals' voluntary behaviors to purchase flood insurance. It is found that the estimated flood hazard conveyed through the U.S. Federal Emergency Management Agency's (FEMA's) flood maps, the intensities and consequences of past storms and flooding events, and perceived flood-related risks significantly affect individual's voluntary purchase of flood insurance. This behavior is also influenced by home ownership, trust in local government, education, and income. These findings have several important policy implications. First, FEMA's flood maps have been effective in conveying local flood risks to coastal residents, and correspondingly influencing their decisions to voluntarily seek flood insurance in the U.S. Gulf Coast. Flood maps therefore should be updated frequently to reflect timely and accurate information about flood hazards. Second, policy makers should design strategies to increase homeowners' trust in the local government, to better communicate flood risks with residents, to address the affordability issue for the low-income, and better inform less educated homeowners through various educational programs. Future studies should examine the voluntary flood insurance behavior across countries that are vulnerable to flooding. Copyright © 2016 Elsevier Ltd. All rights reserved.

Investigating sources of pharmaceutical pollution: Survey of over-the-counter and prescription medication purchasing, use, and disposal practices among university students.

Pharmaceutical pollution in surface waters poses a range of risks to public health and aquatic ecosystems. Consumers contribute to pharmaceutical pollution via use and disposal of medications, though data on such behaviors is limited. This paper investigates the purchasing, use, and disposal practices among a population that has been researched only minimally to date, yet will determine pharmaceutical pollution for decades to come: young adults represented by a university student population. We employed an online, 21-question survey to examine behaviors related to pharmaceuticals among students at the University of Vermont (n = 358). Results indicate that the majority of respondents had purchased medications in the previous 12 months (94%), and had leftover drugs (61%). Contrary to previous studies of older populations, only a small proportion of students had disposed of drugs (18%); municipal trash was the primary route of drug disposal (25%), and very few students disposed drugs via flushing (1%). Less than a quarter of students were aware of drug take-back programs (24%), and only 4% had ever used take-back services. These findings indicate that the university student population may be storing a large volume of unused drugs that will require future disposal. Increasing awareness of, access to, and participation in pro-environment pharmaceutical behaviors, such as purchasing over-the-counter medication in smaller quantities and utilizing drug take-back programs, could minimize future pharmaceutical pollution from this population.

Aims: To measure impact of information, education, and communication intervention (IEC) on rational medicine use, purchase, and stocking behavior. Materials and Methods: This was a pre- and post-design, interventional study. Base data were collected in first visit, using pre tested questionnaire from 500 respondents, who were of either gender, English speaking, at least graduates, permanent residents, and willing to participate. IEC was framed based on problems identified from this data. First intervention was handouts distributed in the second visit, containing information on cost saving in medicine purchase. Second intervention was a lecture session on medicine prices, rational use of medicines, and tips on saving on medicine purchase. Five articles about medicine use and price differences were published in the local newspaper, over 10 days, formed third intervention. After 1 month, post-intervention data was collected using same instrument with some additional questions. Results were analyzed by Chi-square test using Graph Pad prism Version 3.0. Results: Awareness about price variation, self-medication, expiry period, generic and brand quality increased post-intervention. Attitudes toward new, costly, brands, injections, sharing and reusing old prescriptions changed post-intervention. Behavioral changes in stocking habits, adherence to doctors’ advice, getting cash memo, comparing prices, reading labels, were seen post-intervention. Conclusion: People carry false notions about medicines which influence their use and habits. This intervention successfully changed behavior and could bring awareness on many aspects of medicine use.

Behavioral Targeting—Consumer Tracking

NASA Astrophysics Data System (ADS)

Srimani, P. K.; Srinivas, A.

2011-12-01

Behavioral targeting is an online marketing method that collects data on the browsing activities of consumers, in order to `target' more relevant online advertising. Behavioral targeting enables marketers to reach in-market consumers and increases the value of publisher inventory. At the heart of behavioral targeting is a learning-based investigation of consumer behaviors. It helps marketers understand consumers' purchase patterns over time, mapping out a customer's activities based not only on a single purchase but also on an annual or even lifetime basis. As marketers increasingly appreciate the importance of customer lifetime value, behavioral targeting can be a foundation for creating a continuous analytical study of consumer trends and patterns. But as behavioural-targeting systems become more sophisticated and invasive, it is vital that the companies behind them are open with users about what is going on, and give them control over their personal information. The aim of this paper is to explore the various tools and techniques of behavioral targeting and its benefits to online marketing. A multiple—case study approach was used for exploring the effectiveness and acceptance of online marketing in the area of the online marketing.

In the United States, many states have established minimum legal purchase ages for electronic nicotine delivery systems (ENDS) to ban adolescent purchases, but these policies may also affect other related substance use. We explore whether ENDS are substitutes or complements for cigarettes, cigars, smokeless tobacco, and marijuana among adolescents by using variation in state-level implementation of ENDS age purchasing restrictions. We linked data on ENDS age purchasing restrictions to state- and year-specific rates of adolescent tobacco and marijuana use in 2007-2013 from the Youth Risk Behavior Surveillance System. This data provides a nationally representative sample of adolescents who attend public and private schools. We performed a fixed effect regression analysis exploring the influence of ENDS age purchasing restrictions on outcomes of tobacco use and marijuana use, controlling for state and year fixed characteristics, age-race cohorts, cigarette excise taxes, and cigarette indoor use restrictions. For cigarette use, we separate our results into cigarette use frequency. We found causal evidence that ENDS age purchasing restrictions increased adolescent regular cigarette use by 0.8 percentage points. ENDS age purchasing restrictions were not associated with cigar use, smokeless tobacco use, or marijuana use. We document a concerning trend of cigarette smoking among adolescents increasing when ENDS become more difficult to purchase. Copyright © 2016 Elsevier Inc. All rights reserved.

Milliron, Brandy-Joe; Woolf, Kathleen; Appelhans, Bradley M

2012-01-01

This study tested the efficacy of a multicomponent supermarket point-of-purchase intervention featuring in-person nutrition education on the nutrient composition of food purchases. The design was a randomized trial comparing the intervention with usual care (no treatment). A supermarket in a socioeconomically diverse region of Phoenix, AZ. One hundred fifty-three adult shoppers were recruited onsite. The intervention consisted of brief shopping education by a nutrition educator and an explanation and promotion of a supermarket point-of-purchase healthful shopping program that included posted shelf signs identifying healthful foods, sample shopping lists, tips, and signage. Outcomes included purchases of total, saturated, and trans fat (grams/1,000 kcal), and fruits, vegetables, and dark-green/yellow vegetables (servings/1,000 kcal) derived through nutritional analysis of participant shopping baskets. Analysis of covariance compared the intervention and control groups on food purchasing patterns while adjusting for household income. The intervention resulted in greater purchasing of fruit and dark-green/yellow vegetables. No other group differences were observed. Long-term evaluations of supermarket interventions should be conducted to improve the evidence base and to determine the potential for influence on food choices associated with decreased chronic disease incidence.

Development of a method using marketing research data to assess food purchase behavior and consequent nutrient availability for purposes of nutrition surveillance, evaluation of intervention effects, and epidemiologic studies of diet-health relationships. Data collected on household food purchases accrued over a 13-week period were selected by using Universal Product Code numbers and household characteristics from a marketing research database. Universal Product Code numbers for 39,408 dairy product purchases were linked to a standard reference for food composition to estimate the nutrient content of foods purchased over time. Two thousand one hundred sixty-one households located in Victoria, Texas, and surrounding communities who were active members of a frequent shopper program. Demographic characteristics of sample households and the nutrient content of their dairy product purchases were analyzed using frequency distribution, cross tabulation, analysis of variance, and t test procedures. A method for using marketing research data was successfully used to estimate household purchases of specific foods and their nutrient content from a marketing database containing hundreds of thousands of records. Distribution of dairy product purchases and their concomitant nutrients between Hispanic and non-Hispanic households were significant (P<.01, P<.001, respectively) and sustained over time. Purchase records from large, nationally representative panels of shoppers, such as those maintained by major market research companies, might be used to accomplish detailed longitudinal epidemiologic studies or surveillance of national food- and nutrient-purchasing patterns within and between countries and segments of their respective populations.

Theory of health insurance.

PubMed

Nyman, J A

1998-01-01

The conventional explanation for purchasing insurance is to transfer risk. Psychologists, however, have shown that this explanation does not match actual behavior. They find that people generally prefer the risk of no loss at all to the certainty of a smaller actuarially equivalent loss, a situation exactly opposite to the one represented by the purchase of insurance. Nevertheless, people do purchase insurance, so there must be an explanation other than risk transfer for purchasing it. Of the explanations so far advanced, however, none have yet developed a wide acceptance. Regardless of risk issues, people will be more likely to purchase insurance when the premium is low compared to the value of the coverage to the consumer. Moral hazard raises the premium, as does adverse selection. The presence of either makes the purchase of insurance less likely. With health insurance, the tax subsidy can reduce the effective premium to less than the actuarially fair cost of insurance. This would increase the likelihood that health insurance is purchased. Finally, because of the value we place on our health, we desire access to a full range of health care. Health insurance is often the only affordable way of gaining access to this care, given the high costs of many of these procedures.

Food pricing policies to promote healthy diets, such as taxes, price manipulations, and food subsidies, have been tested in different settings. However, little consensus exists about the effect of these policies on the availability of healthy and unhealthy foods, on what foods consumers buy, or on the impact of food purchases on consumer health outcomes. We conducted a systematic review of studies of the effect of food-pricing interventions on retail sales and on consumer purchasing and consumption of healthy foods and beverages. We used MEDLINE, Embase, PsycINFO, Web of Science, ClinicalTrials.gov, and the Cochrane Library to conduct a systematic search for peer-reviewed articles related to studies of food pricing policies. We selected articles that were published in English from January 2000 through December 2016 on the following types of studies: 1) real-world experimental studies (randomized controlled trials, quasi-experimental studies, and natural experiments); 2) population studies of people or retail stores in middle-income and high-income countries; 3) pricing interventions alone or in combination with other strategies (price promotions, coupons, taxes, or cash-back rebates), excluding studies of vending-machine or online sales; and 4) outcomes studies at the retail (stocking, sales) and consumer (purchasing, consumption) levels. We selected 65 articles representing 30 studies for review. Sixteen pricing intervention studies that sought to improve access to healthy food and beverage options reported increased stocking and sales of promoted food items. Most studies (n = 23) reported improvement in the purchasing and consumption of healthy foods or beverages or decreased purchasing and consumption of unhealthy foods or beverages. Most studies assessed promotions of fresh fruits and vegetables (n = 20); however, these foods may be hard to source, have high perishability, and raise concerns about safety and handling. Few of the pricing studies we reviewed discouraged purchasing and consumption of unhealthy foods (n = 6). Many studies we reviewed had limitations, including lack of formative research, process evaluation, or psychosocial and health assessments of the intervention's impact; short intervention duration; or no assessment of food substitutions or the effects of pricing interventions on food purchasing and diets. Pricing interventions generally increased stocking, sales, purchasing, and consumption of promoted foods and beverages. Additional studies are needed to differentiate the potential impact of selected pricing strategies and policies over others.

Optimization Based Data Mining Approah for Forecasting Real-Time Energy Demand

DOE Office of Scientific and Technical Information (OSTI.GOV)

Omitaomu, Olufemi A; Li, Xueping; Zhou, Shengchao

The worldwide concern over environmental degradation, increasing pressure on electric utility companies to meet peak energy demand, and the requirement to avoid purchasing power from the real-time energy market are motivating the utility companies to explore new approaches for forecasting energy demand. Until now, most approaches for forecasting energy demand rely on monthly electrical consumption data. The emergence of smart meters data is changing the data space for electric utility companies, and creating opportunities for utility companies to collect and analyze energy consumption data at a much finer temporal resolution of at least 15-minutes interval. While the data granularity providedmore » by smart meters is important, there are still other challenges in forecasting energy demand; these challenges include lack of information about appliances usage and occupants behavior. Consequently, in this paper, we develop an optimization based data mining approach for forecasting real-time energy demand using smart meters data. The objective of our approach is to develop a robust estimation of energy demand without access to these other building and behavior data. Specifically, the forecasting problem is formulated as a quadratic programming problem and solved using the so-called support vector machine (SVM) technique in an online setting. The parameters of the SVM technique are optimized using simulated annealing approach. The proposed approach is applied to hourly smart meters data for several residential customers over several days.« less

Foraging models have rarely been used to address how behavior is altered by the presence of non-foraged foods. Here, choices of store-bought and hunted foods in one Aboriginal community are analyzed. Hunting occurs frequently, but community residents also purchase food from the shop. Increases in the frequency of hunting certain large and small prey are associated with reduced access to food in the shop. Higher-variance hunt types are not associated with shop purchases, but continue to be acquired due to their cultural significance. The variation in these results highlights the complexity of dietary behavior in a mixed economy.

To determine whether listening to a podcast about omega-3 fatty acids (n-3s) while grocery shopping increased shoppers' awareness about and purchases of seafood and other foods rich in n-3s. Repeated-measures design with a convenience sample (n = 56) of grocery shoppers who listened to the podcast while shopping. Pre- and postintervention semistructured interviews were conducted. The Theory of Reasoned Action was the study's framework. Shoppers were primarily females (mean age, 41 ± 15.3 years). Their perceived ability to buy [t(55) = 6.27, P < .0001] and perceived importance regarding buying [t(55) = 3.38, P < .01] n-3-rich foods improved significantly. At least 1 n-3 rich food (mean, 1.5 ± 0.8) was purchased by 30%, and 79% planned future purchases. Podcasts may effectively communicate nutrition information. More research with a larger sample size is needed to evaluate the effects of the podcast on long-term changes in shopping behavior. Copyright © 2014 Society for Nutrition Education and Behavior.

Machine intelligence-based decision-making (MIND) for automatic anomaly detection

NASA Astrophysics Data System (ADS)

Prasad, Nadipuram R.; King, Jason C.; Lu, Thomas

2007-04-01

Any event deemed as being out-of-the-ordinary may be called an anomaly. Anomalies by virtue of their definition are events that occur spontaneously with no prior indication of their existence or appearance. Effects of anomalies are typically unknown until they actually occur, and their effects aggregate in time to show noticeable change from the original behavior. An evolved behavior would in general be very difficult to correct unless the anomalous event that caused such behavior can be detected early, and any consequence attributed to the specific anomaly. Substantial time and effort is required to back-track the cause for abnormal behavior and to recreate the event sequence leading to abnormal behavior. There is a critical need therefore to automatically detect anomalous behavior as and when they may occur, and to do so with the operator in the loop. Human-machine interaction results in better machine learning and a better decision-support mechanism. This is the fundamental concept of intelligent control where machine learning is enhanced by interaction with human operators, and vice versa. The paper discusses a revolutionary framework for the characterization, detection, identification, learning, and modeling of anomalous behavior in observed phenomena arising from a large class of unknown and uncertain dynamical systems.

One way in which to modify food purchases is to change prices through tax policy, subsidy policy, or both. We reviewed the growing body of experimental research conducted in the laboratory and in the field that investigates the following: the extent to which price changes influence purchases of targeted and nontargeted foods, total energy, or macronutrients purchased; the interaction of price changes with adjunctive interventions; and moderators of sensitivity to price changes. After a brief overview of economic principles and observational research that addresses these issues, we present a targeted review of experimental research. Experimental research suggests that price changes modify purchases of targeted foods, but research on the overall nutritional quality of purchases is mixed because of substitution effects. There is mixed support for combining price changes with adjunctive interventions, and there are no replicated findings on moderators to price sensitivity in experiments. Additional focused research is needed to better inform food policy development with the aim of improving eating behavior and preventing obesity. PMID:22378726

Starting from 1 January 2007, electronic locking devices based on proof-of-age (via electronic cash cards or a European driving licence) were installed in approximately 500,000 vending machines across Germany to restrict the purchase of cigarettes to those over the age of 16. To examine changes in the number of tobacco vending machines before and after the introduction of these new measures. The total number of commercial tobacco sources in 2 selected districts (70,000 inhabitants) in Cologne were recorded and mapped. This major German city was the ideal setting for this study as investigators were able to use existing sociogeographical data from the area. A complete inventory was compiled in autumn 2005 and 2007. A total of 780 students aged 12 to 15 were also interviewed in the study areas. The main outcome measures were quantities and locations of commercial tobacco sources. Between 2005 and 2007 the total number of tobacco sources decreased from 315 to 277 within the study area. Although the most obvious reduction was detected in the number of outdoor vending machines (-48%), the number of indoor vending machines also decreased by 8%. Adolescents changed from vending machines to other sources for cigarettes, particularly kiosks or friends (+31% points usage rate, p<0.001; +35% points usage rate, p<0.001, respectively). Although the number of tobacco vending machines decreased, this has not had a significant impact on cigarette acquisition by underage smokers as they were able to circumvent this new security measure in several different ways.

Commercial sex workers (CSWs) in the Russian Federation are at high risk of HIV infection and transmission as a result of unsafe sexual and injecting behaviors. Their clients might be at increased risk of acquiring HIV; however, little is known about the population of men purchasing sex services. This study aims to investigate factors associated with a history of purchasing sex services by men in Saint Petersburg and Leningrad Oblast, Russian Federation. Data were collected as part of a cross-sectional study offering free anonymous rapid HIV testing in Saint Petersburg and Leningrad Oblast in 2014; in total, 3565 men aged 18 years and older provided information about their behaviors associated with risk of acquiring HIV during face-to-face interviews. Prevalence of CSW use in our study was 23.9%. Multivariable analyses using log-binomial regression were stratified by self-reported HIV testing during the 12 months preceding the study interview. In both strata, older age, multiple sex partners, and a history of sex with an injection drug user (IDU) were associated with an elevated prevalence ratio (PR) for history of purchasing sex services, although the strength of the association differed by strata. Among men who reported recent HIV testing, condom use (PR = 1.22, 90% confidence interval (CI) 1.0, 1.48) was associated with a history of purchasing sex services, and among men who did not report recent HIV testing, having a consistent sex partner was associated with purchasing sex services (PR = 1.23, 90% CI 1.1, 1.37). The high prevalence of CSW service use and associations found in this study raise serious concerns about potential for sexual HIV transmission and should be investigated more closely.

Student access to competitive foods in elementary schools: trends over time and regional differences.

To examine the availability of competitive foods in elementary schools. Nationally representative mail-back survey. United States public and private elementary schools during the 2006-2007, 2007-2008, 2008-2009, and 2009-2010 school years. Survey respondents at 2647 public and 1205 private elementary schools. The availability of foods offered in competitive venues. Elementary school students' access to foods in competitive venues on campus (vending machines, school stores, snack bars, or à la carte lines) remained constant over time. As of the 2009-2010 school year, approximately half of all public and private elementary school students could purchase foods in 1 or more competitive venues on campus. Sugary foods were available to almost all students with access to competitive foods on campus. Public elementary school students in the South had more access to competitive food venues and greater availability of salty and sweet products in those venues compared with students in other parts of the country; however, they also had greater availability of healthier foods, such as fruits and vegetables. Many elementary school students can purchase competitive foods on campus. Most students with access to competitive venues could purchase sweet products, but healthier foods were less widely available.

Thermometers that measure core (internal) body temperature are the gold standard for monitoring temperature. Despite that most modern hemodialysis machines are equipped with an internal blood monitor that measures core body temperature, current practice is to use peripheral thermometers. A better understanding of how peripheral thermometers compare with the dialysis machine thermometer may help guide practice. The study followed a prospective cross-sectional design. Hemodialysis patients were recruited from 2 sites in Calgary, Alberta (April - June 2017). Body temperatures were obtained from peripheral (temporal artery) and dialysis machine thermometers concurrently. Paired t-tests, Bland-Altman plots, and quantile-quantile plots were used to compare measurements from the two devices and to explore potential factors affecting temperature in hemodialysis patients. The mean body temperature of 94 hemodialysis patients measured using the temporal artery thermometer (36.7 °C) was significantly different than the dialysis machine thermometer (36.4 °C); p < 0.001. The mean difference (0.27 °C) appeared to be consistent across average temperature (range: 35.8-37.3 °C). Temperature measured by the temporal artery thermometer was statistically and clinically higher than that measured by the dialysis machine thermometer. Using the dialysis machine to monitor body temperature may result in more accurate readings and is likely to reduce the purchasing and maintenance costs associated with manual temperature readings, as well as easing the workload for dialysis staff.

This study reports findings from the International Alcohol Control (IAC) study that assesses the impact of alcohol control policy on consumption and policy-related behaviors. Modeled on the International Tobacco Control study that uses longitudinal surveys with comparison between countries, the baseline survey was carried out in New Zealand. This study reports analysis of the purchasing behavior respondents report separately for on- and off-premise outlets, providing validation data for both alcohol consumption and reported prices. New Zealand is a high-income country with an adult per capita alcohol consumption (as of 2011) of 9.5 l. The survey was carried out among a nationally representative sample of drinkers. Interview data on place and time of purchase, amounts purchased, price paid, and consumption (beverage and location specific) was collected. Relationships between policy relevant variables and consumption were modeled taking into account demographic variables. Validation was provided by government data on alcohol available for consumption, aggregate expenditure and prices from the Consumer Price Index. Drinkers paying low prices at on- or off-licensed premises had higher odds of consuming 6+ drinks on a typical occasion, as did drinkers purchasing alcohol at later times. Regarding frequency, drinkers purchasing at later times were more likely to be daily drinkers. Lower price in off licenses but not on licenses predicted daily drinking. The data collected accounted for approximately 96% of alcohol available for consumption and the prices accounted for 98% of aggregate expenditure. Valid survey data were collected to give an accurate picture of alcohol consumption and prices paid by drinkers. Heavy drinkers were more likely to buy cheaper alcohol and purchase at later times; 2 policy issues under discussion in many settings. This analysis suggests the IAC study that has the potential to provide data to contribute to the debate on appropriate policy responses to reduce alcohol-related harm.

Background: School canteens represent an opportune setting in which to deliver public health nutrition strategies because of their wide reach and frequent use by children. Online school-canteen ordering systems, where students order and pay for their lunch online, provide an avenue to improve healthy canteen purchases through the application of consumer-behavior strategies that have an impact on purchasing decisions. Objective: We assessed the efficacy of a consumer-behavior intervention implemented in an online school-canteen ordering system in reducing the energy, saturated fat, sugar, and sodium contents of primary student lunch orders. Design: A cluster-randomized controlled trial was conducted that involved 2714 students (aged 5-12 y) from 10 primary schools in New South Wales, Australia, who were currently using an online canteen ordering system. Schools were randomized in a 1:1 ratio to receive either the intervention (enhanced system) or the control (standard online ordering only). The intervention included consumer-behavior strategies that were integrated into the online ordering system (targeting menu labeling, healthy food availability, placement, and prompting). Results: Mean energy (difference: -567.25 kJ; 95% CI: -697.95, -436.55 kJ; P < 0.001), saturated fat (difference: -2.37 g; 95% CI: -3.08, -1.67 g; P < 0.001), and sodium (difference: -227.56 mg; 95% CI: -334.93, -120.19 mg; P < 0.001) contents per student lunch order were significantly lower in the intervention group than in the control group at follow-up. No significant differences were observed for sugar (difference: 1.16 g; 95% CI: -0.50, 2.83 g; P = 0.17). Conclusions: The study provides strong evidence supporting the effectiveness of a consumer-behavior intervention using an existing online canteen infrastructure to improve purchasing behavior from primary school canteens. Such an intervention may represent an appealing policy option as part of a broader government strategy to improve child public health nutrition.

One of the major objectives of industry is to curtail costs. An element, among others, that enables to achieve such goal is the efficiency of the production cycle machines. Such efficiency lies in the reliability of the upkeeping operations. Among maintenance procedures, measuring and analyzing vibrations is a way to detect structure modifications over the machine's lifespan. Further, the availability of a mathematical model describing the influence of each individual part of the machine on the total dynamic behavior of the whole machine may help localizing breakdowns during diagnosis operations. The paper hereof illustrates an analytical-numerical model which can simulate the behavior of a rolling housing. The aforesaid mathematical model has been obtained by FEM techniques, the dynamic response by mode superposition and the synthesis of the vibration time sequence in the frequency versus by FFT numerical techniques.

2015-01-01

The machine tool equipped with the dual-drive servo feed system could realize high feed speed as well as sharp precision. Currently, there is no report about the thermal behaviors of the dual-drive machine, and the current research of the thermal characteristics of machines mainly focuses on steady simulation. To explore the influence of thermal characterizations on the precision of a jib boring machine assembled dual-drive feed system, the thermal equilibrium tests and the research on thermal-mechanical transient behaviors are carried out. A laser interferometer, infrared thermography and a temperature-displacement acquisition system are applied to measure the temperature distribution and thermal deformation at different feed speeds. Subsequently, the finite element method (FEM) is used to analyze the transient thermal behaviors of the boring machine. The complex boundary conditions, such as heat sources and convective heat transfer coefficient, are calculated. Finally, transient variances in temperatures and deformations are compared with the measured values, and the errors between the measurement and the simulation of the temperature and the thermal error are 2 °C and 2.5 μm, respectively. The researching results demonstrate that the FEM model can predict the thermal error and temperature distribution very well under specified operating condition. Moreover, the uneven temperature gradient is due to the asynchronous dual-drive structure that results in thermal deformation. Additionally, the positioning accuracy decreases as the measured point became further away from the motor, and the thermal error and equilibrium period both increase with feed speeds. The research proposes a systematical method to measure and simulate the boring machine transient thermal behaviors.

Private dental practice can be achieved through either outright ownership or an associateship in conjunction with senior dentists; the decision depends on personal and professional objectives and goals. Once a decision is made, the time and effort required to identify an appropriate practice, negotiate the terms of purchase or associateship, and transition to the new practice can be daunting. This article reviews the process and provides an overview of the general steps involved in the evaluation of a dental practice for purchase or associateship. With appropriate knowledge and preparation, due diligence, and ethical and sensitive behavior, transitioning to private practice can be successful and lead to professional and personal fulfillment.

To assess the impacts associated with a grocery store tour point-of-purchase intervention using podcasts about omega-3 fatty acid (n-3)-rich food items. A repeated-measures secondary data analysis of food purchase records obtained from a convenience sample of shoppers' loyalty cards. Shoppers (n = 251) who had listened to podcasts regarding n-3-rich foods while shopping. The number of omega-3-rich food purchases made according to food or food category by participants determined via spreadsheets obtained from grocery store chain. Descriptive statistics were performed on demographic characteristics. Wilcoxon signed-rank tests were used to assess whether food purchases increased from 6 months before to 6 months after intervention. Correlations assessed the relationship between intentions to purchase n-3-rich foods expressed on the intervention day with actual long-term n-3-rich food purchases. Nonparametric Kruskal-Wallis ANOVAs and Wilcoxon signed-rank tests were used to analyze differences between changes made and demographic variables (ie, participants' gender, race, and education levels). Most shoppers (59%) increased n-3-rich food purchases, with significant mean purchase changes (t[172] = -6.9; P < .001; pre = 0.2 ± 0.7; post = 3.6 ± 5.1). Podcasts are promising nutrition education tools. Longer studies could assess whether lasting change results from podcast use. Copyright © 2017 Society for Nutrition Education and Behavior.

To examine differences in diet and food purchasing behaviors between Black and White older women living in urban neighborhoods. Cross-sectional observational study. Urban neighborhoods in Washington, DC, USA. Community-dwelling White and Black women of age 65 and older. Participants were queried on diet via 24-hour recalls, food purchasing habits, their use of neighborhood resources and local travel patterns. Frequency and location of self-reported food purchasing and consumption were compared by race. In 2014 and 2015, 49 White and 44 Black older women were enrolled in the study. Compared to Whites, Blacks reported lower daily caloric intake (mean (SD) 1314 (404) vs. 1529 (448), p=0.02), with a higher percent of calories from protein and fat 1.8 (7.0), p=0.03), and a slightly higher polyunsaturated to saturated fat ratio (p=0.05). Blacks had substantially lower alternate healthy eating index (AHEI) (33.5 (10.2) vs. 43.9 (10.8) of 80 possible points, p<0.001), daily intake (grams) of total fiber (15.3 (8.1) vs. 22.9 (8.5), p<0.001), insoluble fiber (10.8 (6.9) vs. 15.9 (6.5), p<0.001), and soluble fiber (4.5 (2.0) vs. 6.9 (2.8), p<0.001). Blacks had lower intake of micronutrients, alcohol and caffeine. Blacks shopped for groceries less often (4.4 (3.0) vs. 6.2 (3.0) monthly; p=0.006) and spent a longer time traveling to stores (15.8 (9.1) vs. 11.5 (7.2) minutes per trip, p=0.02). A lower percent of Blacks walked to stores (14% vs. 40%, p=0.003) and a higher percent of Blacks rode in a car with someone else (33% vs. 6%, p<0.001). In an urban setting, food consumption and purchasing behaviors differed substantially between older Black and White women, which should be further investigated and considered to promote healthy eating in older populations.

Currently, time of alcohol purchase is not part of the policies to regulate alcohol consumption in South Korea. This study was conducted to determine the relationship between alcohol purchasing time and alcohol use disorder. The survey for this study was conducted in geographically diverse regions of South Korea in 2012. Respondents' purchasing behaviors for both on-licensed (i.e., allows for consumption within the premises) and off-licensed (i.e., where alcohol is consumed off the premises) outlets and time of alcohol consumption were collected. Alcohol consumption patterns were examined using the Rapid Alcohol Problem Screen 4 (RAPS4). Data were also analyzed by age, gender and purchasing time. Results showed that among the off-licensed premises, supermarkets appear to be the most popular venue while for on-licensed premises; alcohol was generally consumed inside hotels/pubs regardless of age and gender of the purchaser. Purchasing of alcohol was highest during the day and early evening period (9:00 a.m. to 9:59 p.m.). Females are most likely to abuse alcohol than males during the early morning period and is that period after 12:00 midnight. Analysis suggests that the survey instrument used in the International Alcohol Control Study is being used to collect data on alcohol purchasing time consumption; therefore, the potential is there to provide accurate results to contribute appropriate policy responses to reduce alcohol related-harm.

Obesity and physical inactivity are responsible for more than 365,000 deaths per year and contribute substantially to rising healthcare costs in the US, making clear the need for effective public health interventions. Calorie labeling on menus has been implemented to guide consumer ordering behaviors, but effects on calories purchased has been minimal. In this project, we tested the effect of physical activity calorie expenditure (PACE) food labels on actual point-of-decision food purchasing behavior as well as physical activity. Using a two-group interrupted time series cohort study design in three worksite cafeterias, one cafeteria was assigned to the intervention condition, and the other two served as controls. Calories from food purchased in the cafeteria were assessed by photographs of meals (accompanied by notes made on-site) using a standardized calorie database and portion size-estimation protocol. Primary outcomes will be average calories purchased and minutes of moderate to vigorous physical activity (MVPA) by individuals in the cohorts. We will compare pre-post changes in study outcomes between study groups using piecewise generalized linear mixed model regressions (segmented regressions) with a single change point in our interrupted time-series study. The results of this project will provide evidence of the effectiveness of worksite cafeteria menu labeling, which could potentially inform policy intervention approaches. Labels that convey information in a more readily understandable manner may be more effective at motivating behavior change. Strengths of this study include its cohort design and its robust data capture methods using food photographs and accelerometry.

Most young adults do not consume recommended levels of fruits and vegetables (F/V), and interventions to increase F/V-related behaviors among this understudied population are needed. Therefore, it is important to identify correlates of F/V intake among young adults to guide intervention development. This cross-sectional study used data from an online survey to identify factors related to young adults' F/V purchasing, preparation, and consumption, and to explore between-factor relationships using mediation analysis. In 2010, 1,201 college students in Minnesota completed questionnaires assessing F/V behaviors as well as perceptions of F/V-related individual, social, and environmental factors. Factor analysis identified questionnaire items assessing similar constructs. Seven factors were identified (personal barriers, F/V knowledge, family, friends, neighborhood, access barriers, and campus) and evaluated for relationships with F/V purchasing, preparation, and consumption using linear regression. Results revealed that perceived personal barriers (eg, lacking cooking skills) were inversely related to all F/V outcomes. Perception that family and friends eat healthfully and neighborhood access to F/V were positively related to all outcomes. Individual-, social-, and environment-level perceptions were related to purchasing, preparation, and consumption, and the effects of these factors were similar when accounting for mediated effects. Factors at all three levels and the ways in which these various factors operate together may be important to consider in future efforts to improve F/V behaviors among young adults.

To investigate if acute sleep deprivation affects food purchasing choices in a mock supermarket. On the morning after one night of total sleep deprivation (TSD) or after one night of sleep, 14 normal-weight men were given a fixed budget (300 SEK-approximately 50 USD). They were instructed to purchase as much as they could out of a possible 40 items, including 20 high-caloric foods (>2 kcal/g) and 20 low-caloric foods (<2 kcal/g). The prices of the high-caloric foods were then varied (75%, 100% (reference price), and 125%) to determine if TSD affects the flexibility of food purchasing. Before the task, participants received a standardized breakfast, thereby minimizing the potential confound produced by hunger. In addition, morning plasma concentrations of the orexigenic hormone ghrelin were measured under fasting conditions. Independent of both type of food offered and price condition, sleep-deprived men purchased significantly more calories (+9%) and grams (+18%) of food than they did after one night of sleep (both P < 0.05). Morning plasma ghrelin concentrations were also higher after TSD (P < 0.05). However, this increase did not correlate with the effects of TSD on food purchasing. This experiment demonstrates that acute sleep loss alters food purchasing behavior in men. Copyright © 2013 The Obesity Society.

Retail point-of-sale guardianship and juvenile tobacco purchases: assessing the prevention capabilities of undergraduate college students.

This randomized experiment evaluates the attitudes and behavioral intentions of 458 undergraduate college students about intervening with the intent of preventing an illegal retail purchase of tobacco products by a minor after exposure to a factorial combination of three pieces of information. MANOVA results show that none of the treatment conditions, considered alone, are correlated with increased attitudes or behavioral intentions; however, there is a significant interaction effect on attitudes when information portraying a potentially annoying situation is combined with information about the costs associated with youth tobacco use. Post-hoc t tests suggest that this effect is concentrated among non-tobacco using respondents.

Consumer Behavior and the Plug-In Electric Vehicle Purchase Decision Process: A Research Synthesis

Taylor, Margaret; Fujita, K. Sydney

This report synthesizes consumer behavior research as it pertains to the plug-in electric vehicle (PEV) purchase decision process. The purpose is to clarify what is known about the vital role consumers play in the U.S. PEV market as it matures to become less policy-reliant and more representative of the U.S., both spatially and demographically. A more representative PEV market will: help OEMs recoup more of their R&D investments in PEVs; help American consumers access the economic and performance benefits of PEVs; and help the U.S. become more energy independent while improving air quality-related public health and reducing greenhouse gas emissions.

State-of-the-Art machine learning architectures (e.g. Extreme Learning Machines, Convolutional Deep Networks) are trained on physical models to learn the Resident Space Object (RSO) features in the vectorized energy and momentum states and parameters. The mapping from measurements to vectorized energy and momentum states and parameters enables behavior characterization via clustering in the features space and subsequent RSO classification. Additionally, Space Object Behavioral Ontologies (SOBO) are employed to define and capture the domain knowledge-base (KB) and BNs are constructed from the SOBO in a semi-automatic fashion to execute probabilistic reasoning over conclusions drawn from trained classifiers and/or directly from processed data. Such an approach enables integrating machine learning classifiers and probabilistic reasoning to support higher-level decision making for space domain awareness applications. The innovation here is to use these methods (which have enjoyed great success in other domains) in synergy so that it enables a "from data to discovery" paradigm by facilitating the linkage and fusion of large and disparate sources of information via a Big Data Science and Analytics framework.

Skip the trip: air travelers' behavioral responses to pandemic influenza.

Theory suggests that human behavior has implications for disease spread. We examine the hypothesis that individuals engage in voluntary defensive behavior during an epidemic. We estimate the number of passengers missing previously purchased flights as a function of concern for swine flu or A/H1N1 influenza using 1.7 million detailed flight records, Google Trends, and the World Health Organization's FluNet data. We estimate that concern over "swine flu," as measured by Google Trends, accounted for 0.34% of missed flights during the epidemic. The Google Trends data correlates strongly with media attention, but poorly (at times negatively) with reported cases in FluNet. Passengers show no response to reported cases. Passengers skipping their purchased trips forwent at least $50 M in travel related benefits. Responding to actual cases would have cut this estimate in half. Thus, people appear to respond to an epidemic by voluntarily engaging in self-protection behavior, but this behavior may not be responsive to objective measures of risk. Clearer risk communication could substantially reduce epidemic costs. People undertaking costly risk reduction behavior, for example, forgoing nonrefundable flights, suggests they may also make less costly behavior adjustments to avoid infection. Accounting for defensive behaviors may be important for forecasting epidemics, but linking behavior with epidemics likely requires consideration of risk communication.

Train stations provide opportunities for food purchases and many consumers are exposed to these venues daily, on their commute to and from work. This study aimed to describe the food environment that commuters are exposed to at train stations in NSW. One hundred train stations were randomly sampled from the Greater Sydney Metropolitan region, representing a range of demographic areas. A purpose-designed instrument was developed to collect information on the availability, promotion and cost of food and beverages in vending machines. Items were classified as high/low in energy according to NSW school canteen criteria. Of the 206 vending machines identified, 84% of slots were stocked with high-energy food and beverages. The most frequently available items were chips and extruded snacks (33%), sugar-sweetened soft drinks (18%), chocolate (12%) and confectionery (10%). High energy foods were consistently cheaper than lower-energy alternatives. Transport sites may cumulatively contribute to excess energy consumption as the items offered are energy dense. Interventions are required to improve train commuters' access to healthy food and beverages.

High resolution X-ray microCT (computerized tomography) can be used to image a variety of objects, including temperature-sensitive materials. In cases where the sample must be chilled or frozen to maintain sample integrity, either the microCT machine itself must be placed in a refrigerated chamber, or a relatively expensive commercial cold stage must be purchased. We describe here the design and construction of a low-cost custom cold stage suitable for use in a microCT imaging system. Our device uses a boron nitride sample holder, two-stage Peltier cooler, fan-cooled heat sink, and electronic controller to maintain sample temperatures as low as −25 °Cmore » ± 0.2 °C for the duration of a tomography acquisition. The design does not require modification to the microCT machine, and is easily installed and removed. Our custom cold stage represents a cost-effective solution for refrigerating CT samples for imaging, and is especially useful for shared equipment or machines unsuitable for cold room use.« less

We review the literature on the relation between narcissism and consumer behavior. Consumer behavior is sometimes guided by self-related motives (e.g., self-enhancement) rather than by rational economic considerations. Narcissism is a case in point. This personality trait reflects a self-centered, self-aggrandizing, dominant, and manipulative orientation. Narcissists are characterized by exhibitionism and vanity, and they see themselves as superior and entitled. To validate their grandiose self-image, narcissists purchase high-prestige products (i.e., luxurious, exclusive, flashy), show greater interest in the symbolic than utilitarian value of products, and distinguish themselves positively from others via their materialistic possessions. Our review lays the foundation for a novel methodological approach in which we explore how narcissism influences eye movement behavior during consumer decision-making. We conclude with a description of our experimental paradigm and report preliminary results. Our findings will provide insight into the mechanisms underlying narcissists’ conspicuous purchases. They will also likely have implications for theories of personality, consumer behavior, marketing, advertising, and visual cognition. PMID:24711797

The increase adoption of Internet among young users in Malaysia provides high prospect for online seller. Young users aged between 18 and 25 years old are important to online sellers because they are actively involved in online purchasing and this group of online buyers is expected to dominate future online market. Therefore, examining online sellers’ website quality and online buyers’ purchase intention is crucial. Based on the Theory of planned behavior (TPB), a conceptual model of online sellers’ website quality and purchase intention of online buyers was developed. E-tailQ instrument was adapted in this study which composed of website design, reliability/fulfillment, security, privacy & trust, and customer service. Using online questionnaire and convenience sampling procedure, primary data were obtained from 240 online buyers aged between 18 to 25 years old. It was discovered that website design, website reliability/fulfillment, website security, privacy & trust, and website customer service positively and significantly influence intention of online buyers to continuously purchase via online channels. This study concludes that online sellers’ website quality is important in predicting online buyers’ purchase intention. Recommendation and implication of this study were discussed focusing on how online sellers should improve their website quality to stay competitive in online business.

Modifying the school food environment is on the national agenda as one strategy to improve the nutritional quality of children's diets. Because few environmental-level interventions have been rigorously evaluated, the evidence base to inform programs and policies is limited. Of concern is the impact that changes to cafeteria offerings will have on participation in school meal programs. This study evaluates school lunch participation in the setting of a year-long middle school cafeteria intervention by examining the association between body mass index (BMI), sociodemographics, and the purchases of school lunch meals. IMOVE meals were healthier choices that met stringent nutritional criteria and were offered alongside standard lunch meals. Students who were overweight had a significantly higher purchase rate for both types of meals compared to those with a healthy BMI. Non-white race, younger age, being male, and low-income status were also significantly associated with participation in school lunch. Results indicate that nutritionally vulnerable students participate in school lunch and are equally likely to buy healthy alternatives or standard meals. This behavioral observation has important implications for school foodservice programs and policies. These results are timely given recent federal legislation to improve the school food environment to influence students' food choice behaviors.

The Human Papilloma Virus (HPV) vaccination provides substantial protection, and it is best to be taken before the age of twelve. Taiwan approved HPV vaccines since 2006. However, very few female adolescent have been vaccinated until now. To examine whether the parents' socio-economic status matters in deciding to purchase HPV vaccination for their daughters based on the theory of planned behavior. A structured questionnaire to collect 394 responses from parents of adolescent girls in Taiwan. Data was coded to categorize relevant socio-economic classes, and was analyzed with SPSS. The behavior intentions of parents with low (mean= 5.28) and high (5.01) socio-economic status are significantly stronger than the moderate (4.56) in deciding to purchase the HPV vaccination. Socio-economic factor has a slightly negative impact (B= -0.08), and attitude (0.68), subjective norms (0.16), and behavior control (0.32) have positive impacts on the parents' intention. Major impacts on the decision to purchase an HPV vaccination for their adolescent was not due to the parents' socio-economic status but the parent's attitude. As the major predictor of a less complicated decision, attitudes toward the HPV vaccination should be reinforced through continuous communications between service providers and patient-advocate groups.

Consumer and product-specific characteristics influencing the effect of nutrition, health and risk reduction claims on preferences and purchase behavior - A systematic review.

The research on nutrition, health, and risk reduction claims (NHR claims) shows a lack of consensus as to whether these claims have a positive or negative effect on consumer's preferences and purchase behavior. This issue has been highlighted by many authors. Therefore, a comprehensive literature review was performed to find reasons for contradictory results. First, a theoretical framework was developed which divided the determinants of the effects of NHR claims on consumers' preferences and purchase behavior into consumer and product-specific characteristics. Additionally, a categorization for the different NHR claim types was constructed to make the studies comparable. Afterwards, the scientific literature from the 1980s until May 2017 was scanned and 66 articles were found to be relevant. Consumer-specific characteristics such as nutrition knowledge, health motivation, familiarity, and socio-demographic characteristics were found to influence the NHR claim effect. Important product-specific characteristics were the perceived healthiness of the food product, the interaction between the product and the nutrient in the NHR claim, and the interaction between the claimed benefit and the NHR claim type. The consumer's nutrition knowledge and the product's perceived healthiness were deemed to be the most promising determinants for further investigation. Copyright © 2018 Elsevier Ltd.

Vending machines account for food sales and revenue in schools. We examined 3 strategies for promoting the sale of lower-calorie food products from vending machines in high schools in the Netherlands. A school-based randomized controlled trial was conducted in 13 experimental schools and 15 control schools. Three strategies were tested within each experimental school: increasing the availability of lower-calorie products in vending machines, labeling products, and reducing the price of lower-calorie products. The experimental schools introduced the strategies in 3 consecutive phases, with phase 3 incorporating all 3 strategies. The control schools remained the same. The sales volumes from the vending machines were registered. Products were grouped into (1) extra foods containing empty calories, for example, candies and potato chips, (2) nutrient-rich basic foods, and (3) beverages. They were also divided into favorable, moderately unfavorable, and unfavorable products. Total sales volumes for experimental and control schools did not differ significantly for the extra and beverage products. Proportionally, the higher availability of lower-calorie extra products in the experimental schools led to higher sales of moderately unfavorable extra products than in the control schools, and to higher sales of favorable extra products in experimental schools where students have to stay during breaks. Together, availability, labeling, and price reduction raised the proportional sales of favorable beverages. Results indicate that when the availability of lower-calorie foods is increased and is also combined with labeling and reduced prices, students make healthier choices without buying more or fewer products from school vending machines. Changes to school vending machines help to create a healthy school environment. © 2012, American School Health Association.

Point-of-purchase (POP) information at food stores could help promote healthy dietary habits. However, it has been difficult to evaluate the effects of such intervention on customers' behavior. We objectively evaluated the usefulness of POP health information for vegetables in the modification of customers' purchasing behavior by using the database of a point-of-sales (POS) system. Two supermarket stores belonging to the same chain were assigned as the intervention store (store I) and control store (store C). POP health information for vegetables was presented in store I for 60 days. The percent increase in daily sales of vegetables over the sales on the same date of the previous year was compared between the stores by using the database of the POS system, adjusting for the change in monthly visitors from the previous year (adjusted ∆sales). The adjusted ∆sales significantly increased during the intervention period (Spearman's ρ = 0.258, P for trend = 0.006) at store I but did not increase at store C (ρ = -0.037, P for trend = 0.728). The growth of the mean adjusted ∆sales of total vegetables from 30 days before the intervention period through the latter half of the intervention period was estimated to be greater at store I than at store C by 18.7 percentage points (95% confidence interval 1.6-35.9). Health-related POP information for vegetables in supermarkets can encourage customers to purchase and, probably, consume vegetables.

The effect of sensory and extrinsic attributes on consumer intentions to purchase the Japanese traditional fermented soybean product natto was evaluated using conjoint analysis. Six attributes with 2 levels each were chosen and manipulated: price (high compared with low), the country of origin of the soybeans (domestic compared with imported), stickiness (strong compared with moderate), smell (rich compared with moderate), attached seasonings (attached compared with no attached seasonings), and the environmental friendliness of the packaging (high compared with low). A fractional factorial design was applied and 8 hypothetical product labels were produced. A sample of 479 Japanese housewives ranked these product labels based on their purchase intentions. Overall purchase intention was affected by country of origin, attached seasonings, and price; those attributes accounted for 81.0%, while the sensory attributes of the product accounted for 19.0% of purchase intents. In order to estimate market segments for the natto products based on consumer preference, a cluster analysis was performed. It identified 4 segments of consumers: 1 oriented to attached seasonings, another conscious of the price, and the other 2 oriented to origins. The behavioral and demographic characteristics of the respondents had a limited influence on segment membership.   This research was conducted to understand how consumers valuate various sensory and nonsensory product attributes based on their assessment of the overall product in the case of Japanese fermented soy product (natto). The data of this research would be of great importance both in understanding consumer behavior and in designing strategies for product development.

The method used in this research is case study with rating scale and rank spearman analysis. The sampling technique is the accidental random sampling method consist of 30 respondents. The consumer’s decision making process consist of five stages, namely the recognition of needs, information searching, alternative evaluation, process of purchasing, and the evaluation of results. The results showed that at the stage of recognition of needs the motivation of purchasing freshwater fish because respondents are very fond of ornamental freshwater fish, at the stage of information search, the information sources are from the print media and friends or neighborhood. At the stage of alternative evaluation, the reason consumers buy ornamental freshwater fish because the quality of good products. The stage of purchasing decision process consumers bought 1-5 fish with frequency of purchase 1 time per month. The evaluation of results of post-purchasing consumers feel very satisfied with the fish products and the price is very affordable. To observe the factors that influence purchasing motivation of consumers, spearman rank test is the method. The results showed that the quality and price of the product are the factors that most influence the purchase decision of ornamental freshwater fish with the range of student-t value 3,968 and 2,107.

This study assessed the impact of changes in school food policy on student lunch consumption in middle schools. Two years of lunch food records were collected from students at three middle schools in the Houston, Texas area. During the first year, no changes occurred in the school food environment. After that school year was completed, chips and dessert foods were removed from the snack bars of all schools by the Food Service Director. Students recorded the amount and source of food and beverage items consumed. Point-of-service purchase machines provided a day-by-day electronic data file with food and beverage purchases from the snack bars during the 2-year period. Independent t-tests and time series analyses were used to document the impact of the policy change on consumption and sales data between the two years. In general, student consumption of sweetened beverages declined and milk, calcium, vitamin A, saturated fat and sodium increased after the policy change. Snack chips consumption from the snack bar declined in year 2; however, consumption of snack chips and candy from vending increased and the number of vending machines in study schools doubled during the study period. Ice cream sales increased significantly in year 2. Policy changes on foods sold in schools can result in changes in student consumption from the targeted environments. However, if all environments do not make similar changes, compensation may occur.

A Perspective on Consumers 3.0: They Are Not Better Decision-Makers than Previous Generations

This perspective article builds upon the theory of local thinking in interpretation and prediction of consumer behavior in a contemporary world of information overload. It is shown that even informed and socially and environmentally responsible consumers (consumers 3.0) exhibit selective recall, limited attention, and bounded search in the perception and interpretation of price and quality of purchases. Their decisions fall into local cognitive frames, which specifically focus attention only on a narrow structure and content of the choice. The cognitive frames can be established by recent or regular purchases, but also extreme or primary purchase experiences. The article includes a short conceptual review of car, food, clothing, insurance, drugs, paintings, and other product purchases showing that the local cognitive frames often lead to bad bargains across various sectors. The article presents several suggestions for future research. PMID:27375527

Purpose To examine the association between foods sold in school vending machines and students’ dietary behaviors. Methods The 2005-2006 US Health Behavior in School Aged Children (HBSC) survey was administered to 6th to 10th graders and school administrators. Students’ dietary intake was estimated with a brief food frequency measure. Administrators completed questions about foods sold in vending machines. For each food intake behavior, a multilevel regression analysis modeled students (level 1) nested within schools (level 2), with the corresponding food sold in vending machines as the main predictor. Control variables included gender, grade, family affluence and school poverty. Analyses were conducted separately for 6th to 8th and 9th to 10th grades. Results Eighty-three percent of schools (152 schools, 5,930 students) had vending machines which primarily sold foods of minimal nutritional values (soft drinks, chips and sweets). In younger grades, availability of fruits/vegetables and chocolate/sweets was positively related to the corresponding food intake, with vending machine content and school poverty explaining 70.6% of between-school variation in fruit/vegetable consumption, and 71.7% in sweets consumption. In older grades, there was no significant effect of foods available in vending machines on reported consumption of those foods. Conclusions Vending machines are widely available in US public schools. In younger grades, school vending machines were related to students’ diets positively or negatively, depending on what was sold in them. Schools are in a powerful position to influence children’s diets; therefore attention to foods sold in them is necessary in order to try to improve children’s diets. PMID:21185519

In younger grades, availability of fruit and/or vegetables and chocolate and/or sweets was positively related to the corresponding food intake, with vending machine content and school poverty index providing an explanation for 70.6% of between-school variation in fruit and/or vegetable consumption and 71.7% in sweets consumption. Among the older grades, there was no significant effect of food available in vending machines on reported consumption of those food. Vending machines are widely available in public schools in the United States. In younger grades, school vending machines were either positively or negatively related to the diets of the students, depending on what was sold in them. Schools are in a powerful position to influence the diets of children; therefore, attention to the food sold at school is necessary to try to improve their diets.

Objectives Currently, time of alcohol purchase is not part of the policies to regulate alcohol consumption in South Korea. This study was conducted to determine the relationship between alcohol purchasing time and alcohol use disorder. Methods The survey for this study was conducted in geographically diverse regions of South Korea in 2012. Respondents’ purchasing behaviors for both on-licensed (i.e., allows for consumption within the premises) and off-licensed (i.e., where alcohol is consumed off the premises) outlets and time of alcohol consumption were collected. Alcohol consumption patterns were examined using the Rapid Alcohol Problem Screen 4 (RAPS4). Data were also analyzed by age, gender and purchasing time. Results Results showed that among the off-licensed premises, supermarkets appear to be the most popular venue while for on-licensed premises; alcohol was generally consumed inside hotels/pubs regardless of age and gender of the purchaser. Purchasing of alcohol was highest during the day and early evening period (9:00 a.m. to 9:59 p.m.). Females are most likely to abuse alcohol than males during the early morning period and is that period after 12:00 midnight. Conclusion Analysis suggests that the survey instrument used in the International Alcohol Control Study is being used to collect data on alcohol purchasing time consumption; therefore, the potential is there to provide accurate results to contribute appropriate policy responses to reduce alcohol related-harm.

2017-01-01

Mobile shopping is increasing in prevalence and has become a necessary part of many people's daily lives. However, one main channel for mobile shopping, mobile shopping applications (apps), has not been thoroughly investigated. This study focused on mobile text advertising delivered from mobile shopping apps using the intention to purchase as the dependent variable for testing its marketing effect. In the context of a promotion focus vs. a prevention focus, we used Higgins' regulatory focus theory combined with Ajzen's TPB and Herzog's U&G to analyze the mechanism by which consumers formulate an intention to purchase in a mobile advertising context. This empirical study surveyed 320 consumers who had made a purchase using a mobile shopping app in the previous month. The results showed that infotainment, irritation, and subjective norms were significantly associated with attitudes; in turn, attitudes mediated the impact of these three factors on the intention to purchase. Moreover, a high promotion focus not only strengthened the positive effect of infotainment on attitudes but also intensified the mediation effect of attitudes between infotainment and the intention to purchase. A high prevention focus also consolidated the negative effect of irritation on attitudes as well as reinforced the mediation effect of attitudes between irritation and the intention to purchase. Furthermore, attitudes, subjective norms, and perceived behavioral control collectively impacted the intention to purchase. These findings shed light on ways to customize goods information in mobile advertising and have strong theoretical and practical implications.

Bruner, Natalie R; Johnson, Matthew W

2014-03-01

Drug purchasing tasks have been successfully used to examine demand for hypothetical consumption of abused drugs including heroin, nicotine, and alcohol. In these tasks, drug users make hypothetical choices whether to buy drugs, and if so, at what quantity, at various potential prices. These tasks allow for behavioral economic assessment of that drug's intensity of demand (preferred level of consumption at extremely low prices) and demand elasticity (sensitivity of consumption to price), among other metrics. However, a purchasing task for cocaine in cocaine-dependent individuals has not been investigated. This study examined a novel Cocaine Purchasing Task and the relation between resulting demand metrics and self-reported cocaine use data. Participants completed a questionnaire assessing hypothetical purchases of cocaine units at prices ranging from $0.01 to $1,000. Demand curves were generated from responses on the Cocaine Purchasing Task. Correlations compared metrics from the demand curve to measures of real-world cocaine use. Group and individual data were well modeled by a demand curve function. The validity of the Cocaine Purchasing Task was supported by a significant correlation between the demand curve metrics of demand intensity and O max (determined from Cocaine Purchasing Task data) and self-reported measures of cocaine use. Partial correlations revealed that after controlling for demand intensity, demand elasticity and the related measure, P max, were significantly correlated with real-world cocaine use. Results indicate that the Cocaine Purchasing Task produces orderly demand curve data, and that these data relate to real-world measures of cocaine use.

Family medicine residents are at risk for burnout due to extended work hours, lack of control over their work schedule, and challenging work situations and environments. Building resiliency can prevent burnout and may improve a resident's quality of life and health behavior. This report describes a program designed to build resiliency, the ability to bounce back from stress, in family medicine residents in a medium sized U.S. residency training program. Interactive sessions emphasized building self-awareness, coping skills, strengths and meaning in work, time management, self-care, and connections in and outside of medicine to support resident well-being. System changes which fostered wellness were also implemented. These changes included increasing the availability of fresh fruits in the conference and call room, purchasing an elliptical exercise machine for the on call room, and offering a few minutes of mindfulness meditation daily to the inpatient residents. Results to date show excellent acceptance of the program by trainees, increased consumption of nutritious foods, more personal exercise, and self-reported decreased overreactions to stress. Resiliency programs can effectively serve to meet accreditation requirements while fostering residents' abilities to balance personal and professional demands. © The Author(s) 2015.

People are increasingly leaving digital traces of their daily activities through interacting with their digital environment. Among these traces, financial transactions are of paramount interest since they provide a panoramic view of human life through the lens of purchases, from food and clothes to sport and travel. Although many analyses have been done to study the individual preferences based on credit card transaction, characterizing human behavior at larger scales remains largely unexplored. This is mainly due to the lack of models that can relate individual transactions to macro-socioeconomic indicators. Building these models, not only can we obtain a nearly real-time information about socioeconomic characteristics of regions, usually available yearly or quarterly through official statistics, but also it can reveal hidden social and economic structures that cannot be captured by official indicators. In this paper, we aim to elucidate how macro-socioeconomic patterns could be understood based on individual financial decisions. To this end, we reveal the underlying interconnection of the network of spending leveraging anonymized individual credit/debit card transactions data, craft micro-socioeconomic indices that consists of various social and economic aspects of human life, and propose a machine learning framework to predict macro-socioeconomic indicators.

Currently, many studies focus on how the environment can be changed to encourage healthier eating behavior, referred to as choice architecture or "nudging." However, to date, these strategies are not often investigated in real-life settings, such as worksite cafeterias, or are only done so on a short-term basis. The objective of this study is to examine the effects of a healthy worksite cafeteria ["worksite cafeteria 2.0" (WC 2.0)] intervention on Dutch employees' purchase behavior over a 12-wk period. We conducted a randomized controlled trial in 30 worksite cafeterias. Worksite cafeterias were randomized to either the intervention or control group. The intervention aimed to encourage employees to make healthier food choices during their daily worksite cafeteria visits. The intervention consisted of 14 simultaneously executed strategies based on nudging and social marketing theories, involving product, price, placement, and promotion. Adjusted multilevel models showed significant positive effects of the intervention on purchases for 3 of the 7 studied product groups: healthier sandwiches, healthier cheese as a sandwich filling, and the inclusion of fruit. The increased sales of these healthier meal options were constant throughout the 12-wk intervention period. This study shows that the way worksite cafeterias offer products affects purchase behavior. Situated nudging and social marketing-based strategies are effective in promoting healthier choices and aim to remain effective over time. Some product groups only indicated an upward trend in purchases. Such an intervention could ultimately help prevent and reduce obesity in the Dutch working population. This trial was registered at the Dutch Trial Register (http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=5372) as NTR5372.

Food is a primary reinforcer, and food reinforcement is related to obesity. The reinforcing value of food can be measured by establishing how hard someone will work to get food on progressive-ratio schedules. An alternative way to measure food reinforcement is a hypothetical purchase task which creates behavioral economic demand curves. This paper studies whether reinforcing value and hypothetical behavioral demand approaches are assessing the same or unique aspects of food reinforcement for low (LED) and high (HED) energy density foods using a combination of analytic approaches in females of varying BMI. Results showed absolute reinforcing value for LED and HED foods and relative reinforcing value were related to demand intensity (r's = 0.20-0.30, p's < 0.01), and demand elasticity (r's = 0.17-0.22, p's < 0.05). Correlations between demographic, BMI and restraint, disinhibition and hunger variables with the two measures of food reinforcement were different. Finally, the two measures provided unique contributions to predicting BMI. Potential reasons for differences between the reinforcing value and hypothetical purchase tasks were actual responding versus hypothetical purchasing, choice of reinforcers versus purchasing of individual foods in the demand task, and the differential role of effort in the two tasks. Examples of how a better understanding of food reinforcement may be useful to prevent or treat obesity are discussed, including engaging in alternative non-food reinforcers as substitutes for food, such as crafts or socializing in a non-food environment, and reducing the value of immediate food reinforcers by episodic future thinking.

Models are needed to understand the emerging capability to track consumers' movements. Therefore, we examined the use of legal and readily available stimulants that vary in their addictive potential (nicotine, caffeine). One hundred sixty-six participants answered the Kessler Psychological Distress Scale (K10), the Severity of Dependence Scale for nicotine and caffeine, and reported the number of times and locations stimulants were purchased and used. On average, nicotine dependent individuals made their purchases from 2 locations, while caffeine dependent individuals consumed caffeine at 2 locations, but some people exhibited a greater range and intensity of use. Stimulant foraging behavior could be described by power laws, and is exacerbated by dependency. The finding has implications for attempts to control substance use.

Video tracking based biological early warning system achieved a great progress with advanced computer vision and machine learning methods. Ability of video tracking of multiple biological organisms has been largely improved in recent years. Video based behavioral monitoring has become a common tool for acquiring quantified behavioral data for aquatic risk assessment. Investigation of behavioral responses under chemical and environmental stress has been boosted by rapidly developed machine learning and artificial intelligence. In this paper, we introduce the fundamental of video tracking and present the pioneer works in precise tracking of a group of individuals in 2D and 3D space. Technical and practical issues suffered in video tracking are explained. Subsequently, the toxic analysis based on fish behavioral data is summarized. Frequently used computational methods and machine learning are explained with their applications in aquatic toxicity detection and abnormal pattern analysis. Finally, advantages of recent developed deep learning approach in toxic prediction are presented. PMID:29849612

One way to increase choice of healthy over unhealthy behaviors is to increase the cost of less healthy alternatives or reduce the cost of healthier alternatives. The influence of price on purchases of healthy and unhealthy foods was evaluated in two laboratory experiments. In Experiment 1, thirty-two 10- to 12-year-old youth were given $5.00 and allowed to purchase multiple portions of a healthy food (fruit or vegetable) and a less healthy food (higher-fat snack). The price of one type of food varied from $0.50 to $2.50, while the price of the other type was held at $1.00. Increasing the price of a type of food reduced purchases of that type of food, but did not lead to substitution with the alternative type of food. In Experiment 2, twenty 10- to 14-year-old youth were given $1.00, $3.00, and $5.00 to purchase healthy and unhealthy foods. The price of each food was raised and lowered by 25% and 50%. Raising the price of healthy or unhealthy foods resulted in decreased purchases of those foods, and income available interacted with price to predict the pattern of substitution of alternative foods. These results show the potential for controlled laboratory studies of price and food purchases, and show that the substitution of healthier for unhealthy food is related to available money.

Combining human and machine intelligence to derive agents' behavioral rules for groundwater irrigation

Hu, Yao; Quinn, Christopher J.; Cai, Ximing; Garfinkle, Noah W.

2017-11-01

For agent-based modeling, the major challenges in deriving agents' behavioral rules arise from agents' bounded rationality and data scarcity. This study proposes a "gray box" approach to address the challenge by incorporating expert domain knowledge (i.e., human intelligence) with machine learning techniques (i.e., machine intelligence). Specifically, we propose using directed information graph (DIG), boosted regression trees (BRT), and domain knowledge to infer causal factors and identify behavioral rules from data. A case study is conducted to investigate farmers' pumping behavior in the Midwest, U.S.A. Results show that four factors identified by the DIG algorithm- corn price, underlying groundwater level, monthly mean temperature and precipitation- have main causal influences on agents' decisions on monthly groundwater irrigation depth. The agent-based model is then developed based on the behavioral rules represented by three DIGs and modeled by BRTs, and coupled with a physically-based groundwater model to investigate the impacts of agents' pumping behavior on the underlying groundwater system in the context of coupled human and environmental systems.

Nutritional profile of Supplemental Nutrition Assistance Program household food and beverage purchases.

Grummon, Anna H; Taillie, Lindsey Smith

Background: The Supplemental Nutrition Assistance Program (SNAP), which is the largest federal nutrition assistance program in the United States, serves nearly 1 of 7 Americans. To date, few studies have examined food and beverage purchase behaviors in SNAP participants with the use of electronic purchase data. Objective: In this cross-sectional study, we examined household store purchases of key food, beverage, and nutrient groups in SNAP participants and nonparticipants. Design: Using a data set of US households' ( n = 98,256 household-by-quarter observations) packaged food and beverage purchases and SNAP status [current participant, income-eligible nonparticipant (income ≤130% of the Federal Poverty Level [FPL]), and higher-income nonparticipants (income >130% of the FPL)] from 3 quarters during 2012-2013, we estimated pooled ordinary least-squares models, clustered at the household level, to examine the association between SNAP status and purchases while controlling for sociodemographic characteristics. We examined purchases of health- and policy-relevant food and beverage groups [e.g., fruit and sugar-sweetened beverages (SSBs)] and nutrients (e.g., total calories and sodium). Results: Regardless of SNAP status, households had low mean purchases of fruit, vegetables, and fiber and high mean purchases of junk foods, saturated fat, and sodium. After adjustment for multiple comparisons and demographic characteristics, we found significant differences by SNAP status of purchases of fruit, processed meat, salty snacks, sweeteners and toppings, SSBs, and total calories, fiber, sugar, and sodium. Several of these differences were clinically important. For example, compared with income-eligible and higher-income nonparticipants, SNAP participants purchased an additional ∼15-20 kcal · person -1 · d -1 from SSBs ( P < 0.0001) and ∼174-195 mg total Na · person -1 · d -1 ( P <0.0001). Results were robust to corrections for sample-selection bias and to the exclusion of observations with potentially misreported SNAP status. Conclusions: American households, including SNAP households, show room for improvement in the nutritional quality of store purchases. New interventions and policies may be needed to improve food and beverage purchases in both SNAP and non-SNAP households. © 2017 American Society for Nutrition.

Sex tourism among men who have sex with men (MSM) may exacerbate transmission of HIV and other sexually transmitted infections (STIs). Sex tourism is defined as purchasing sex with gifts or money outside of one's hometown. Our objective was to characterize the frequency, socio-demographic characteristics, and sexual risk behaviors among Chinese MSM sex tourists. An online, cross-sectional survey for high-risk MSM throughout China was conducted in November 2015 covering sociodemographic characteristics, sexual risk behaviors, and sex tourism. Univariate and multivariable logistic regressions were performed to identify correlates of sex tourism. The mean MSM HIV prevalence of sex tourism journey origins and destinations were compared. Of 1189 MSM who completed the survey, 62 (5%) men identified as sex tourists; among these sex tourists, twenty (32%) traveled primarily to purchase sex and the remainder purchased sex while traveling for another purpose. There was minimal socio-demographic and behavioral difference between the two groups. In multivariable analyses, adjusting for age and income, sex tourism was correlated with high-risk sexual behaviors, higher income (aOR 4.44, 95%CI 1.77-11.18) and living with HIV (aOR 2.79, 95%CI 1.03-7.55). Sex tourism was more often from locations with lower to higher MSM HIV prevalence (mean = 4.47, SD = 2.01 versus mean = 6.86, SD = 5.24). MSM sex tourists were more likely to have risky sexual behaviors and travel to locations with a higher HIV prevalence. MSM sex tourists may be part of core groups that are disproportionately responsible for MSM HIV transmission. Enhanced surveillance and interventions tailored to MSM sex tourists should be considered.

Skip the Trip: Air Travelers' Behavioral Responses to Pandemic Influenza

Theory suggests that human behavior has implications for disease spread. We examine the hypothesis that individuals engage in voluntary defensive behavior during an epidemic. We estimate the number of passengers missing previously purchased flights as a function of concern for swine flu or A/H1N1 influenza using 1.7 million detailed flight records, Google Trends, and the World Health Organization's FluNet data. We estimate that concern over “swine flu,” as measured by Google Trends, accounted for 0.34% of missed flights during the epidemic. The Google Trends data correlates strongly with media attention, but poorly (at times negatively) with reported cases in FluNet. Passengers show no response to reported cases. Passengers skipping their purchased trips forwent at least $50 M in travel related benefits. Responding to actual cases would have cut this estimate in half. Thus, people appear to respond to an epidemic by voluntarily engaging in self-protection behavior, but this behavior may not be responsive to objective measures of risk. Clearer risk communication could substantially reduce epidemic costs. People undertaking costly risk reduction behavior, for example, forgoing nonrefundable flights, suggests they may also make less costly behavior adjustments to avoid infection. Accounting for defensive behaviors may be important for forecasting epidemics, but linking behavior with epidemics likely requires consideration of risk communication. PMID:23526970

To what extent do food purchases reflect shoppers' diet quality and nutrient intake?

Food purchasing is considered a key mediator between the food environment and eating behavior, and food purchasing patterns are increasingly measured in epidemiologic and intervention studies. However, the extent to which food purchases actually reflect individuals' dietary intake has not been rigorously tested. This study examined cross-sectional agreement between estimates of diet quality and nutrient densities derived from objectively documented household food purchases and those derived from interviewer-administered 24-h diet recalls. A secondary aim was to identify moderator variables associated with attenuated agreement between purchases and dietary intake. Primary household food shoppers (N = 196) collected and annotated receipts for all household food and beverage purchases (16,356 total) over 14 days. Research staff visited participants' homes four times to photograph the packaging and nutrition labels of each purchased item. Three or four multiple-pass 24-h diet recalls were performed within the same 14-d period. Nutrient densities and Healthy Eating Index-2010 (HEI-2010) scores were calculated from both food purchase and diet recall data. HEI-2010 scores derived from food purchases (median = 60.9, interquartile range 49.1-71.7) showed moderate agreement (ρc = .57, p < .0001) and minimal bias (-2.0) with HEI-2010 scores from 24-h recalls (median = 60.1, interquartile range 50.8-73.9). The degree of observed bias was unrelated to the number of food/beverage purchases reported or participant characteristics such as social desirability, household income, household size, and body mass. Concordance for individual nutrient densities from food purchases and 24-h diet recalls varied widely from ρc = .10 to .61, with the strongest associations observed for fiber (ρc = .61), whole fruit (ρc = .48), and vegetables (ρc = .39). Objectively documented household food purchases yield an unbiased and reasonably accurate estimate of overall diet quality as measured through 24-h diet recalls, but are generally less useful for characterizing dietary intake of specific nutrients. Thus, some degree of caution is warranted when interpreting food purchase data as a reflection of diet in epidemiological and clinical research. Future work should examine agreement between food purchases and nutritional biomarkers. ClinicalTrials.gov, NCT02073643 . Retrospectively registered.

Comprehensive machine learning analysis of Hydra behavior reveals a stable basal behavioral repertoire

PubMed Central

Taralova, Ekaterina; Dupre, Christophe; Yuste, Rafael

2018-01-01

Animal behavior has been studied for centuries, but few efficient methods are available to automatically identify and classify it. Quantitative behavioral studies have been hindered by the subjective and imprecise nature of human observation, and the slow speed of annotating behavioral data. Here, we developed an automatic behavior analysis pipeline for the cnidarian Hydra vulgaris using machine learning. We imaged freely behaving Hydra, extracted motion and shape features from the videos, and constructed a dictionary of visual features to classify pre-defined behaviors. We also identified unannotated behaviors with unsupervised methods. Using this analysis pipeline, we quantified 6 basic behaviors and found surprisingly similar behavior statistics across animals within the same species, regardless of experimental conditions. Our analysis indicates that the fundamental behavioral repertoire of Hydra is stable. This robustness could reflect a homeostatic neural control of "housekeeping" behaviors which could have been already present in the earliest nervous systems. PMID:29589829

Mandatory labeling of products with top allergens has improved food safety for consumers. Precautionary allergen labeling (PAL), such as "may contain" or "manufactured on shared equipment," are voluntarily placed by the food industry. To establish knowledge of PAL and its impact on purchasing habits by food-allergic consumers in North America. Food Allergy Research & Education and Food Allergy Canada surveyed consumers in the United States and Canada on purchasing habits of food products featuring different types of PAL. Associations between respondents' purchasing behaviors and individual characteristics were estimated using multiple logistic regression. Of 6684 participants, 84.3% (n = 5634) were caregivers of a food-allergic child and 22.4% had food allergy themselves. Seventy-one percent reported a history of experiencing a severe allergic reaction. Buying practices varied on the basis of PAL wording; 11% of respondents purchased food with "may contain" labeling, whereas 40% purchased food that used "manufactured in a facility that also processes." Twenty-nine percent of respondents were unaware that the law requires labeling of priority food allergens. Forty-six percent were either unsure or incorrectly believed that PAL is required by law. Thirty-seven percent of respondents thought PAL was based on the amount of allergen present. History of a severe allergic reaction decreased the odds of purchasing foods with PAL. Almost half of consumers falsely believed that PAL was required by law. Up to 40% surveyed consumers purchased products with PAL. Understanding of PAL is poor, and improved awareness and guidelines are needed to help food-allergic consumers purchase food safely. Copyright © 2016 American Academy of Allergy, Asthma & Immunology.

Objective The main objective of this study was to investigate the relationship between various factors (e.g., sociodemographic, child, and parental factors) and the healthfulness of parental responses to child in-store food purchasing requests. Additionally, a secondary objective is to describe "resist strategies" used by parents to respond to child food-purchasing requests and their efficacy in avoiding conflict. Methods Parent-child dyads (children aged 2-6 years) completed an audio-/visual-recoded food shopping trip at their usual grocery store and time. Recordings of trips were coded for behavioral and environmental factors. Parental healthful response rate (i.e., percent of responses that were healthful) was the primary outcome variable. A healthful response occurred when a parent yielded to a healthful child request, or resisted a non-healthful request. Parents also completed a questionnaire. Kruskal-Wallis tests were used to assess the relationship between the main outcome variable and sociodemographic, child, and parent factors. Results Parents (n = 39) responded healthfully to 62.9 % (±26.7 %) of child food purchasing requests. Low- and middle-income parents, and black and white parents, had significantly higher healthful response rates compared to high-income parents (p = 0.03) and Hispanic/Indian-descent parents (p = 0.02), respectively. Using the "ignore" strategy proved an effective resist strategy in this study, leading to no parent-child conflicts. Conclusions Programming that seeks to improve the healthfulness of food purchasing in families with young children should address unhealthful response behaviors in Hispanic/Indian-descent parents and high-income parents; although, the needs of these groups are different. Further research is needed to confirm and expand on these findings.

Product placement influences consumer choices in retail stores. While sugar sweetened beverage (SSB) manufacturers expend considerable effort and resources to determine how product placement may increase SSB purchases, the information is proprietary and not available to the public health and research community. This study aims to quantify the effect of non-SSB product placement in corner stores on adolescent beverage purchasing behavior. Corner stores are small privately owned retail stores that are important beverage providers in low-income neighborhoods--where adolescents have higher rates of obesity. Using data from a community-based survey in Baltimore and parameters from the marketing literature, we developed a decision-analytic model to simulate and quantify how placement of healthy beverage (placement in beverage cooler closest to entrance, distance from back of the store, and vertical placement within each cooler) affects the probability of adolescents purchasing non-SSBs. In our simulation, non-SSB purchases were 2.8 times higher when placed in the "optimal location"--on the second or third shelves of the front cooler--compared to the worst location on the bottom shelf of the cooler farthest from the entrance. Based on our model results and survey data, we project that moving non-SSBs from the worst to the optional location would result in approximately 5.2 million more non-SSBs purchased by Baltimore adolescents annually. Our study is the first to quantify the potential impact of changing placement of beverages in corner stores. Our findings suggest that this could be a low-cost, yet impactful strategy to nudge this population--highly susceptible to obesity--towards healthier beverage decisions.

Children's dietary-related diseases and their associated costs have expanded dramatically in many countries, making children's food choice a policy issue of increasing relevance. As children spend a considerable amount of money on energy-dense, nutrient-poor (EDNP) products, a better understanding of the main drivers of children's independent food purchase decisions is crucial to move this behavior toward healthier options. The objective of the study is to investigate the role of branding and price in motivating children to choose healthier snack options. The study investigates snack choices of children ages 8 to 11, using a survey and a purchase experiment. The research took place in after-school programs of selected schools in the Boston area. Participants included 116 children. Products in the choice experiment differed on three factors: product type, brand, and price. Data were analyzed using aggregated and mixed logit models. Children's purchase decisions are primarily determined by product type (Importance Value (IV) 56.6%), while brand (IV 22.8%) and price (IV 20.6%) prove to be of less relevance. Only those children who state that they like the familiar brand reveal a preference for the branded product in their purchase decision. Price is a significant predictor of choice when controlling for whether or not children obtain an allowance. It is not simple brand awareness but a child's liking of the brand that determines whether a brand is successful in motivating a child to choose a product. The extent of children's experience with money influences their price responsiveness. To the extent that children who receive an allowance are primarily the ones buying food snacks, higher prices for EDNP snacks could be successful in motivating children to choose a healthier option.

HIV prevention efforts must be comprehensive in their understanding of the factors involved in HIV risk. Male clients, who have received less research attention than female sex workers (FSWs), may experience stigma as a function of purchasing sex. Perceived stigma may be related to poor psychological outcomes, risky psychosexual characteristics, and higher drug and sexual risk behavior among male clients of FSWs. However, perceived stigma of purchasing sex may differ between clients of different ethnic groups. In the present study, we examine the correlates of perceived stigma of purchasing sex among Latino vs. non-Latino male clients of FSWs in Tijuana, Mexico. Using time-location sampling, we recruited 375 male clients (323 Latino, 52 non-Latino) in Tijuana who completed a computerized survey on various measures. We measured perceived stigma of purchasing sex using three items we developed for this study. Using linear regression analyses we found that perceived stigma was associated with greater guilt, a greater feeling of escape from everyday life, and more negative condom attitudes among Latino clients. This was not found among non-Latino clients. Features of Latino culture, like machismo, and how they may relate to stigma of purchasing sex are discussed. PMID:23979714

Objectives To examine differences in diet and food purchasing behaviors between Black and White older women living in urban neighborhoods. Design Cross-sectional observational study. Setting Urban neighborhoods in Washington, DC, USA. Participants Community-dwelling White and Black women of age 65 and older. Measurements Participants were queried on diet via 24-hour recalls, food purchasing habits, their use of neighborhood resources and local travel patterns. Frequency and location of self-reported food purchasing and consumption were compared by race. Results In 2014 and 2015, 49 White and 44 Black older women were enrolled in the study. Compared to Whites, Blacks reported lower daily caloric intake (mean (SD) 1314 (404) vs. 1529 (448), p=0.02), with a higher percent of calories from protein and fat 1.8 (7.0), p=0.03), and a slightly higher polyunsaturated to saturated fat ratio (p=0.05). Blacks had substantially lower healthy eating index (HEI) (33.5 (10.2) vs. 43.9 (10.8) of 80 possible points, p<0.001), daily intake (grams) of total fiber (15.3 (8.1) vs. 22.9 (8.5), p<0.001), insoluble fiber (10.8 (6.9) vs. 15.9 (6.5), p<0.001), and soluble fiber (4.5 (2.0) vs. 6.9 (2.8), p<0.001). Blacks had lower intake of micronutrients, alcohol and caffeine. Blacks shopped for groceries less often (4.4 (3.0) vs. 6.2 (3.0) monthly; p=0.006) and spent a longer time traveling to stores (15.8 (9.1) vs. 11.5 (7.2) minutes per trip, p=0.02). A lower percent of Blacks walked to stores (14% vs. 40%, p=0.003) and a higher percent of Blacks rode in a car with someone else (33% vs. 6%, p<0.001). Conclusions In an urban setting, food consumption and purchasing behaviors differed substantially between older Black and White women, which should be further investigated and considered to promote healthy eating in older populations.

Objective To examine food and beverage choices of preschool-aged children. Design Semistructured observational study. While pretending to be adults during a role-play scenario, children selected food and beverage items from a miniature grocery store stocked with 73 different products, of which 47 foods and beverages were examined in this analysis. Parents self-reported how frequently they purchased specific grocery items. Setting A behavioral laboratory. Participants One hundred twenty children, aged 2 to 6 years, and 1 parent for each child. Main Outcome Measure Children’s total purchases were classified according to the number of healthier and less healthy products they selected as least healthy, somewhat healthy, and most healthy choices. The same categories were used to classify parents’ self-reported purchases. Results Most of the children (70.8%) purchased foods that were categorized as least healthy choices. Only 13 children (10.8%) had shopping baskets consisting of the healthiest choices. On average, children in the group with the least healthy choices purchased the same number of healthier and less healthy products, whereas children in the group with most healthy choices purchased 5 healthier products for each less healthy product selected. The healthfulness of children’s total purchases were significantly (P=.02) predicted by their parents’ purchasing categorization. Conclusions When presented with a wide array of food products, young children chose combinations of healthier and less healthy foods and beverages. The data suggest that children begin to assimilate and mimic their parents’ food choices at a very young age, even before they are able to fully appreciate the implications of these choices.

Bruner, Natalie R.; Johnson, Matthew W.

2013-01-01

Rationale Drug purchasing tasks have been successfully used to examine demand for hypothetical consumption of abused drugs including heroin, nicotine, and alcohol. In these tasks drug users make hypothetical choices whether to buy drugs, and if so, at what quantity, at various potential prices. These tasks allow for behavioral economic assessment of that drug's intensity of demand (preferred level of consumption at extremely low prices) and demand elasticity (sensitivity of consumption to price), among other metrics. However, a purchasing task for cocaine in cocaine-dependent individuals has not been investigated. Objectives This study examined a novel Cocaine Purchasing Task and the relation between resulting demand metrics and self-reported cocaine use data. Methods Participants completed a questionnaire assessing hypothetical purchases of cocaine units at prices ranging from $0.01 to $1,000. Demand curves were generated from responses on the Cocaine Purchasing Task. Correlations compared metrics from the demand curve to measures of real-world cocaine use. Results Group and individual data were well modeled by a demand curve function. The validity of the Cocaine Purchasing Task was supported by a significant correlation between the demand curve metrics of demand intensity and Omax (determined from Cocaine Purchasing Task data) and self-reported measures of cocaine use. Partial correlations revealed that after controlling for demand intensity, demand elasticity and the related measure, Pmax, were significantly correlated with real-world cocaine use. Conclusions Results indicate that the Cocaine Purchasing Task produces orderly demand curve data, and that these data relate to real-world measures of cocaine use. PMID:24217899

People are exposed to persuasive communication across many different contexts: Governments, companies, and political parties use persuasive appeals to encourage people to eat healthier, purchase a particular product, or vote for a specific candidate. Laboratory studies show that such persuasive appeals are more effective in influencing behavior when they are tailored to individuals' unique psychological characteristics. However, the investigation of large-scale psychological persuasion in the real world has been hindered by the questionnaire-based nature of psychological assessment. Recent research, however, shows that people's psychological characteristics can be accurately predicted from their digital footprints, such as their Facebook Likes or Tweets. Capitalizing on this form of psychological assessment from digital footprints, we test the effects of psychological persuasion on people's actual behavior in an ecologically valid setting. In three field experiments that reached over 3.5 million individuals with psychologically tailored advertising, we find that matching the content of persuasive appeals to individuals' psychological characteristics significantly altered their behavior as measured by clicks and purchases. Persuasive appeals that were matched to people's extraversion or openness-to-experience level resulted in up to 40% more clicks and up to 50% more purchases than their mismatching or unpersonalized counterparts. Our findings suggest that the application of psychological targeting makes it possible to influence the behavior of large groups of people by tailoring persuasive appeals to the psychological needs of the target audiences. We discuss both the potential benefits of this method for helping individuals make better decisions and the potential pitfalls related to manipulation and privacy. Copyright © 2017 the Author(s).

Consumption of single cigarettes and quitting behavior: A longitudinal analysis of Mexican smokers

PubMed Central

2011-01-01

Background Previous cross-sectional research has suggested single cigarettes could either promote or inhibit consumption. The present study aimed to assess the effects of single cigarette availability and consumption on downstream quit behavior. Methods We analyzed population-based, longitudinal data from adult smokers who participated in the 2008 and 2010 administrations of the International Tobacco Control Policy Evaluation Survey in Mexico. Results At baseline, 30% of smokers saw single cigarettes for sale on a daily basis, 17% bought singles at their last purchase, and 7% bought singles daily. Smokers who most frequently purchased singles, both in general and specifically to control their consumption, were no more likely to attempt to quit over the 14 month follow-up period than those who did not purchase singles. Frequency of buying singles to reduce consumption had a non-monotonic association with being quit at followup. The odds of being quit was only statistically significant when comparing those who had not bought singles to reduce consumption with those who had done so on a more irregular basis (AOR = 2.30; 95% CI 1.19, 4.45), whereas those who did so more regularly were no more likely to be quit at followup. Frequency of self-reported urges to smoke upon seeing singles for sale was unassociated with either quit attempts or being quit at followup. Conclusions These results suggest that the relationship between singles consumption and quit behavior is complex, with no clear evidence that singles either promote or inhibit downstream quit behavior.

To assess exposure to marketing of unhealthy food products and its relation to food related behavior and BMI in children aged 3-13, from different socioeconomic backgrounds in a south Indian town. Child-parent pairs (n=306) were recruited at pediatric clinics. Exposure to food marketing was assessed by a digital logo recognition test. Children matched 18 logos of unhealthy food (high in fat/sugar/salt) featured in promotion material from the food industry to pictures of corresponding products. Children's nutritional knowledge, food preferences, purchase requests, eating behavior and socioeconomic characteristics were assessed by a digital game and parental questionnaires. Anthropometric measurements were recorded. Recognition rates for the brand logos ranged from 30% to 80%. Logo recognition ability increased with age (p<0.001) and socioeconomic level (p<0.001 comparing children in the highest and lowest of three socioeconomic groups). Adjusted for gender, age and socioeconomic group, logo recognition was associated with higher BMI (p=0.022) and nutritional knowledge (p<0.001) but not to unhealthy food preferences or purchase requests. Children from higher socioeconomic groups in the region had higher brand logo recognition ability and are possibly exposed to more food marketing. The study did not lend support to a link between exposure to marketing and poor eating behavior, distorted nutritional knowledge or increased purchase requests. The correlation between logo recognition and BMI warrants further investigation on food marketing towards children and its potential role in the increasing burden of non-communicable diseases in this part of India.

Point-of-sale is a potentially important opportunity to promote healthy eating through nutrition education and environment modification. The aim of this review was to describe and review the evidence of effectiveness of various types of interventions that have been used at point-of-sale to encourage purchase and/or eating of healthier food and to improve health outcomes, and the extent to which effectiveness was related to intensity, duration and intervention setting. Records from searches in databases were screened and assessed against inclusion criteria. Included studies had risk of bias assessed. Intervention effectiveness was assessed for two outcomes: i) purchase and/or intake of healthier food options and/or nutrient intake; and ii) mediating factors that might effect the primary outcome. The search identified 5635 references. Thirty-two papers met the inclusion criteria. Twelve studies had low risk of bias and were classified as strong, nine were moderate and 11 were weak. Six intervention types and a range of different outcome measures were described in these papers: i) nutrition education and promotion alone through supermarkets/stores; ii) nutrition education plus enhanced availability of healthy food; iii) monetary incentive alone; iv) nutrition education plus monetary incentives; v) nutrition intervention through vending machines; and vi) nutrition intervention through shopping online. The evidence of this review indicates that monetary incentives offered to customers for a short-term look promising in increasing purchase of healthier food options when the intervention is applied by itself in stores or supermarkets. There was a lack of good quality studies addressing all other types of relevant point-of-sale interventions examining change in purchase and/or intake of healthier food options. There were few studies that examined mediating factors that might mediate the effect on the primary outcomes of relevant interventions. A range of intervention types have been used at point-of-sale to encourage healthy purchasing and/or intake of healthier food options and to improve health outcomes. There is a need for more well designed studies on the effectiveness of a range of point-of-sale interventions to encourage healthier eating and improve health outcomes, and of the mediating factors that might impact these interventions.

As of January 01, 2007, electronic locking devices based on proof of age (electronic cash cards or European driving licenses) were installed on 500,000 cigarette vending machines across Germany to restrict the purchase of cigarettes to those over the age of 16 years. In 2009, the age limit was raised to 18 years. The aim of this study was to compare the number of cigarette vending machines and other commercial sources before and after the enactment of the new law and to examine the association between commercial cigarette sources and area socioeconomic status (SES). We recorded and mapped using Geographical Information System software the total number of commercial cigarette sources in 4 selected districts in the major German city of Cologne. The city was the ideal setting for this study as we were able to use existing sociogeographical data from this area. We compiled a complete inventory of commercial cigarette sources in autumn 2005 and 2009. An interim inventory was also completed in 2007. Between 2005 and 2009, the total number of cigarette sources decreased from 369 to 325 within the study area. Although the most obvious reduction was detected in the number of outdoor vending machines (-44%), the number of indoor vending machines also decreased by 5%. In 2005 as well as in 2009, we found significantly fewer commercial cigarette sources in districts with above-average SES than in districts with below-average SES. Although the number of overall cigarette vending machines decreased, the disparity in distribution of cigarette sources between socially advantaged and disadvantaged areas increased.

Monitoring changes in the nutritional content of food/beverage products and shifts in consumer purchasing behaviors is needed to measure the effectiveness of efforts by both food manufacturers and policy makers to improve dietary quality in the United States. To examine changes in the nutritional content (eg, energy, saturated fat, and sugar density) of ready-to-eat (RTE) grain-based dessert (GBD) products manufactured and purchased between 2005 and 2012. Nutrition Facts panel information from commercial databases was linked to RTE GBD products purchased by households (N=134,128) in the Nielsen Homescan longitudinal dataset 2005-2012. Linear regression models were used to examine changes in the energy, saturated fat, and sugar density of RTE GBD products manufactured in each year between 2005 and 2012. Random effects models controlling for demographics, household composition/size, and geographic location were used to examine changes in household purchases of RTE GBD products (in grams) and the average energy, saturated fat, and sugar density of RTE GBD products purchased. The saturated fat density (grams/100 g) of RTE GBD products increased significantly from 6.5±0.2 in 2005 to 7.3±0.2 and 7.9±0.2 for pre-existing and newly introduced products in 2012, respectively. Between 2005 and 2012, the energy density (kilocalories/100 g) of RTE GBD products purchased decreased significantly from 433±0.2 to 422±0.2, the saturated fat density (grams/100 g) of products purchased increased significantly from 6.3±0.01 to 6.6±0.01, the sugar density (grams/100 g) of products purchased decreased significantly from 32.4±0.03 to 31.3±0.02, and household purchases of RTE GBD products (in grams) decreased by 24.1%±0.4%. These results highlight an opportunity for both food manufacturers and public health officials to develop new strategies to shift consumer purchases toward products with lower energy, saturated fat, and sugar densities in addition to decreasing overall purchases of RTE GBDs.

Computational Analysis of Behavior.

PubMed

Egnor, S E Roian; Branson, Kristin

2016-07-08

In this review, we discuss the emerging field of computational behavioral analysis-the use of modern methods from computer science and engineering to quantitatively measure animal behavior. We discuss aspects of experiment design important to both obtaining biologically relevant behavioral data and enabling the use of machine vision and learning techniques for automation. These two goals are often in conflict. Restraining or restricting the environment of the animal can simplify automatic behavior quantification, but it can also degrade the quality or alter important aspects of behavior. To enable biologists to design experiments to obtain better behavioral measurements, and computer scientists to pinpoint fruitful directions for algorithm improvement, we review known effects of artificial manipulation of the animal on behavior. We also review machine vision and learning techniques for tracking, feature extraction, automated behavior classification, and automated behavior discovery, the assumptions they make, and the types of data they work best with.

Background Nutritional labelling is advocated as a means to promote healthier food purchasing and consumption, including lower energy intake. Internationally, many different nutritional labelling schemes have been introduced. There is no consensus on whether such labelling is effective in promoting healthier behaviour. Objectives To assess the impact of nutritional labelling for food and non-alcoholic drinks on purchasing and consumption of healthier items. Our secondary objective was to explore possible effect moderators of nutritional labelling on purchasing and consumption. Search methods We searched 13 electronic databases including CENTRAL, MEDLINE and Embase to 26 April 2017. We also handsearched references and citations and sought unpublished studies through websites and trials registries. Selection criteria Eligible studies: were randomised or quasi-randomised controlled trials (RCTs/Q-RCTs), controlled before-and-after studies, or interrupted time series (ITS) studies; compared a labelled product (with information on nutrients or energy) with the same product without a nutritional label; assessed objectively measured purchasing or consumption of foods or non-alcoholic drinks in real-world or laboratory settings. Data collection and analysis Two authors independently selected studies for inclusion and extracted study data. We applied the Cochrane 'Risk of bias' tool and GRADE to assess the quality of evidence. We pooled studies that evaluated similar interventions and outcomes using a random-effects meta-analysis, and we synthesised data from other studies in a narrative summary. Main results We included 28 studies, comprising 17 RCTs, 5 Q-RCTs and 6 ITS studies. Most (21/28) took place in the USA, and 19 took place in university settings, 14 of which mainly involved university students or staff. Most (20/28) studies assessed the impact of labelling on menus or menu boards, or nutritional labelling placed on, or adjacent to, a range of foods or drinks from which participants could choose. Eight studies provided participants with only one labelled food or drink option (in which labelling was present on a container or packaging, adjacent to the food or on a display board) and measured the amount consumed. The most frequently assessed labelling type was energy (i.e. calorie) information (12/28). Eleven studies assessed the impact of nutritional labelling on purchasing food or drink options in real-world settings, including purchases from vending machines (one cluster-RCT), grocery stores (one ITS), or restaurants, cafeterias or coffee shops (three RCTs, one Q-RCT and five ITS). Findings on vending machines and grocery stores were not interpretable, and were rated as very low quality. A meta-analysis of the three RCTs, all of which assessed energy labelling on menus in restaurants, demonstrated a statistically significant reduction of 47 kcal in energy purchased (MD −46.72 kcal, 95% CI −78.35, −15.10, N = 1877). Assuming an average meal of 600 kcal, energy labelling on menus would reduce energy purchased per meal by 7.8% (95% CI 2.5% to 13.1%). The quality of the evidence for these three studies was rated as low, so our confidence in the effect estimate is limited and may change with further studies. Of the remaining six studies, only two (both ITS studies involving energy labels on menus or menus boards in a coffee shop or cafeteria) were at low risk of bias, and their results support the meta-analysis. The results of the other four studies which were conducted in a restaurant, cafeterias (2 studies) or a coffee shop, were not clearly reported and were at high risk of bias. Seventeen studies assessed the impact of nutritional labels on consumption in artificial settings or scenarios (henceforth referred to as laboratory studies or settings). Of these, eight (all RCTs) assessed the effect of labels on menus or placed on a range of food options. A meta-analysis of these studies did not conclusively demonstrate a reduction in energy consumed during a meal (MD −50 kcal, 95% CI −104.41, 3.88, N = 1705). We rated the quality of the evidence as low, so our confidence in the effect estimate is limited and may change with further studies. Six laboratory studies (four RCTs and two Q-RCTs) assessed the impact of labelling a single food or drink option (such as chocolate, pasta or soft drinks) on energy consumed during a snack or meal. A meta-analysis of these studies did not demonstrate a statistically significant difference in energy (kcal) consumed (SMD 0.05, 95% CI −0.17 to 0.27, N = 732). However, the confidence intervals were wide, suggesting uncertainty in the true effect size. We rated the quality of the evidence as low, so our confidence in the effect estimate is limited and may change with further studies. There was no evidence that nutritional labelling had the unintended harm of increasing energy purchased or consumed. Indirect evidence came from five laboratory studies that involved mislabelling single nutrient content (i.e. placing low energy or low fat labels on high-energy foods) during a snack or meal. A meta-analysis of these studies did not demonstrate a statistically significant increase in energy (kcal) consumed (SMD 0.19, 95% CI −0.14to 0.51, N = 718). The effect was small and the confidence intervals wide, suggesting uncertainty in the true effect size. We rated the quality of the evidence from these studies as very low, providing very little confidence in the effect estimate. Authors' conclusions Findings from a small body of low-quality evidence suggest that nutritional labelling comprising energy information on menus may reduce energy purchased in restaurants. The evidence assessing the impact on consumption of energy information on menus or on a range of food options in laboratory settings suggests a similar effect to that observed for purchasing, although the evidence is less definite and also of low quality. Accordingly, and in the absence of observed harms, we tentatively suggest that nutritional labelling on menus in restaurants could be used as part of a wider set of measures to tackle obesity. Additional high-quality research in real-world settings is needed to enable more certain conclusions. Further high-quality research is also needed to address the dearth of evidence from grocery stores and vending machines and to assess potential moderators of the intervention effect, including socioeconomic status. Nutritional labelling to promote healthier consumption and purchasing of food or drinks A poor diet including excessive energy intake is an important cause of ill health. Nutritional labelling may help people to make healthier food choices. What is the aim of this review? This review investigated whether nutritional labels (i.e. labels providing information about nutritional content) persuade people to buy or consume different (healthy) kinds of food. We searched for all available evidence to answer this question and found 28 studies. Key messages There is evidence to suggest that nutritional labelling, with energy information (e.g. calorie counts) on menus, may reduce energy purchased in restaurants, but more high-quality studies are needed to make this finding more certain. What was studied in the review? Some studies assessed buying food or drinks from vending machines, grocery stores, restaurants, cafeterias, or coffee shops. Others assessed the amount of food or drink consumed during a snack or meal in an artificial setting or scenario (referred to as laboratory studies or settings). What are the main results of the review? Nutritional labelling on restaurant menus reduced the amount of energy (i.e. calories) purchased, but the quality of the three studies that contributed to this finding was low, so our confidence in the effect estimate is limited and may change with further studies. Eight studies assessed this same type of intervention in laboratory settings, but instead of evaluating how much energy participants purchased, these studies evaluated how much energy participants consumed. These studies did not conclusively demonstrate a reduction in energy consumed when menus or foods were labelled, and they were also of low quality. In addition, six laboratory studies assessed how much energy participants consumed when they were given one food or drink option with or without labels, and five laboratory studies assessed how much energy participants consumed when foods were experimentally labelled as low energy or low fat when they were actually high-energy foods (i.e. mislabelling). Results from these two groups of studies were inconclusive and of low, or in the case of mislabelling studies, very low quality. We found some studies that assessed labelling on vending machines and grocery stores, but their results were not easy to interpret, so we could not use them to inform this review. How up-to-date is this review? The evidence is current to 26 April 2017. PMID:29482264

2017-12-01

From the analysis of ensemble variability to improving simulation performance, machine learning algorithms can play a powerful role in understanding the behavior of atmospheric and climate models. To learn about model behavior, we create training and testing data sets through ensemble techniques that sample different model configurations and values of input parameters, and then use supervised machine learning to map the relationships between the inputs and outputs. Following this procedure, we have used support vector machines, random forests, gradient boosting and other methods to investigate a variety of atmospheric and climate model phenomena. We have used machine learning to predict simulation crashes, estimate the probability density function of climate sensitivity, optimize simulations of the Madden Julian oscillation, assess the impacts of weather and emissions uncertainty on atmospheric dispersion, and quantify the effects of model resolution changes on precipitation. This presentation highlights recent examples of our applications of machine learning to improve the understanding of climate and atmospheric models.

Aim The aim of the current study was to evaluate tobacco product purchasing in the Experimental Tobacco Marketplace (ETM) among male and female smokers who also use e-cigarettes. We hypothesized a high substitution profile for e-cigarettes and that males would purchase more Snus than females. Methods The ETM is an online market used in clinical abuse liability research to mimic real-world purchasing patterns. Tobacco products, including each participant’s usual choice of conventional and e-cigarettes, were presented along with a price and description of nicotine content. Participants were endowed with an account balance based on the number of cigarettes and e-cigarettes consumed per week. Each participant was exposed to four ETM sessions in random order during which the price of conventional cigarettes was manipulated. Results Cigarette consumption decreased as price increased. A mixed factor three-way ANOVA revealed a significant main effect of price (i.e., more alternative products were purchased at higher cigarette prices), product (i.e., more e-cigarettes were purchased than gum, lozenges, and Snus), and sex (i.e., males purchased more than females). A significant three-way interaction indicated that males purchased more e-cigarettes, Snus, and dip than females at higher cigarette prices. Conclusion This study suggests that the user profile of cigarette smokers is associated with behavioral economic measures of alternative product substitution and indicates that the evaluation of nicotine replacement products should be considered for both males and females separately.

OBJECTIVES Schools have an important role to play in obesity prevention, but little is known about the food environment in small, predominately rural schools. The primary purpose of this study was to compare the availability and student purchasing of foods sold outside of the reimbursable meals program through a la carte (ALC) or vending (i.e., competitive foods) in small (n = 7) and large (n = 6) Kansas high schools. METHODS A cross-sectional observational study design was used to capture the number of ALC and vending items available and purchased, and the fat and caloric content of all available and purchased items on a single school day between January and May 2005. RESULTS Small schools had significantly fewer vending machines than large schools [median=3.0 (range=2.0–5.0) versus 6.5 (range=4.0–8.0), p<0.01]. Vending and ALC items at small schools contained a median of 2.3 fewer fat grams per item (p≤0.05), while vending products contained a median of 25.0 fewer calories per item (p≤0.05) than at large schools. Significantly less fat (median= −15.4 grams/student) and fewer calories (median= −306.8 kcal/student) were purchased per student from all competitive food sources and from ALC (median= −12.9 fat grams and −323.3 kcal/student) by students in small schools compared to students in large schools (p≤0.05). CONCLUSIONS The findings, which highlight less availability and lower energy content from competitive foods at small compared to large schools, have implications for understanding how small schools support their food service programs with limited dependence on competitive foods and the impact that food and nutrition professionals can have on the school environment by providing more oversight into the nutritional quality of foods available.

Sapkota, V P; Bhusal, U P

2017-01-01

Nepal is pursuing Social Health Insurance as a way of mobilizing revenues to achieve Universal Health Coverage. The Social Health Insurance governance encourages service providers to maintain quality and efficiency in services provision by practicing strategic purchasing. Social Health Security Programme is a social protection program which aspires to achieve the goals of Social Health Insurance. Social Health Security Development Committee needs to consider following experiences to function as a strategic purchaser. The Social Health Security Development Committee need to be an independent body instead of falling under Ministry of Health. Similarly, purchasing of health services needs to be made strategic, i.e., Social Health Security Development Committee should use its financial power to guide the provider behavior that will eventually contribute to achieving the goals of quality and efficiency in service provision. The other social health security funds should be merged with Social Health Security Development Committee and develop a single national fund. Finally, the state has to regulate and monitor the performance of the SHI agency.

Cultivating gratitude and giving through experiential consumption.

Walker, Jesse; Kumar, Amit; Gilovich, Thomas

2016-12-01

Gratitude promotes well-being and prompts prosocial behavior. Here, we examine a novel way to cultivate this beneficial emotion. We demonstrate that 2 different types of consumption-material consumption (buying for the sake of having) and experiential consumption (buying for the sake of doing)-differentially foster gratitude and giving. In 6 studies we show that reflecting on experiential purchases (e.g., travel, meals out, tickets to events) inspires more gratitude than reflecting on material purchases (e.g., clothing, jewelry, furniture), and that thinking about experiences leads to more subsequent altruistic behavior than thinking about possessions. In Studies 1-2b, we use within-subject and between-subjects designs to test our main hypothesis: that people are more grateful for what they've done than what they have. Study 3 finds evidence for this effect in the real-world setting of online customer reviews: Consumers are more likely to spontaneously mention feeling grateful for experiences they have bought than for material goods they have bought. In our final 2 studies, we show that experiential consumption also makes people more likely to be generous to others. Participants who contemplated a significant experiential purchase behaved more generously toward anonymous others in an economic game than those who contemplated a significant material purchase. It thus appears that shifting spending toward experiential consumption can improve people's everyday lives as well as the lives of those around them.

Jansen, Paul; Toomey, Traci L; Nelson, Toben F; Fabian, Lindsey E A; Lenk, Kathleen M; Forster, Jean L

Few studies have described youth cigarette sources in terms of whether the cigarettes were free or purchased. Understanding the different ways youth obtain tobacco can guide development of interventions to more effectively reduce youth smoking. To determine the propensity for youth to purchase cigarettes versus obtain cigarettes for free, and the factors associated with each obtainment method. Our sample included 812 youth ages 12-17 who reported ever smoking a whole cigarette. Our outcome was the source of the last cigarette smoked (purchased vs. free) and independent variables included demographics, smoking behaviors, and smoking status of parents/siblings/friends. We conducted logistic regression to assess relationships between outcome and independent variables. Eighty-four percent of youth obtained their last cigarette for free and 16% purchased their last cigarette. Youth who smoked less and had less weekly spending money were more likely to have obtained their last cigarette for free. Youth smokers appear to have a high propensity to obtain their cigarette for free, particularly those who smoke relatively infrequently. Interventions that target sources of free cigarettes have the potential to reduce the progression of youth smoking at a critical stage in its development.

Farmers' markets have the potential to improve the health of underserved communities, shape people's perceptions, values, and behaviors about healthy eating, and serve as a social space for both community members and vendors. This study explored the influence of health care provider communication and role modeling for diabetic patients within the context of a farmers' market located at a federally qualified health center. Although provider communication about diet decreased over time, communication strategies included: providing patients with "prescriptions" and vouchers for market purchases; educating patients about diet; and modeling healthy purchases. Data from patient interviews and provider surveys revealed that patients enjoyed social aspects of the market including interactions with their health care provider, and providers distributed prescriptions and vouchers to patients, shopped at the market, and believed that the market had potential to improve the health of staff and patients of the federally qualified health center. Provider modeling of healthy behaviors may influence patients' food-related perceptions and dietary behaviors.

Although antibiotics are prescription-only medicine in Indonesia, they can be purchased without prescription. This qualitative study elicited beliefs about nonprescribed antibiotics use informed by the theory of planned behavior to develop a questionnaire for an expanded theory of planned behavior survey. Twenty-five (N = 25) adults with experience of using nonprescribed antibiotics were interviewed. Content analysis was applied. Participants reported that the use of nonprescribed antibiotics was advantageous in term of saving time and money and of reducing the number of medicines that need to be purchased, in contrast to a perception of what occurs with medical prescriptions. Potential adverse effects, poor health outcomes, and antimicrobial resistance were the perceived disadvantages. Facilitators of such use were the availability of over-the-counter antibiotics and successful experience in using antibiotics. Medication for children was the perceived barrier to such use. Family members and friends, especially those with health education background, approved of such use. © 2012 APJPH.

The purpose of this study was to identify and examine consumer perception of corporate social responsibility (CSR) in China's sports lottery industry, and the effect of perceived CSR initiatives on sports lottery consumption behavior. Research participants (N = 4,980), selected based on a computer-generated, randomly stratified multistage sampling process, comprised Chinese residents who had purchased sports lottery tickets in the past 12 months. They completed a questionnaire that was derived from a qualitative research process. A factor analysis extracted two factors associated with perceptions of CSR in China's sports lottery administration: Regulatory and Prevention Responsibilities and Product Development Responsibility. Logistic regression analyses revealed that these two factors were influential of consumer behavior (i.e., relative and absolute expenditure, purchasing frequency, and time commitment). This study represents an initial effort to understand the dimensions of perceived CSR associated with Chinese sports lottery. The findings signify the importance of enforcing CSR in sports lottery administration.

Morphological change in machines accelerates the evolution of robust behavior

PubMed Central

Bongard, Josh

2011-01-01

Most animals exhibit significant neurological and morphological change throughout their lifetime. No robots to date, however, grow new morphological structure while behaving. This is due to technological limitations but also because it is unclear that morphological change provides a benefit to the acquisition of robust behavior in machines. Here I show that in evolving populations of simulated robots, if robots grow from anguilliform into legged robots during their lifetime in the early stages of evolution, and the anguilliform body plan is gradually lost during later stages of evolution, gaits are evolved for the final, legged form of the robot more rapidly—and the evolved gaits are more robust—compared to evolving populations of legged robots that do not transition through the anguilliform body plan. This suggests that morphological change, as well as the evolution of development, are two important processes that improve the automatic generation of robust behaviors for machines. It also provides an experimental platform for investigating the relationship between the evolution of development and robust behavior in biological organisms. PMID:21220304

Machinability of Green Powder Metallurgy Components: Part I. Characterization of the Influence of Tool Wear

2007-06-01

The green machining process is an interesting approach for solving the mediocre machining behavior of high-performance powder metallurgy (PM) steels. This process appears as a promising method for extending tool life and reducing machining costs. Recent improvements in binder/lubricant technologies have led to high green strength systems that enable green machining. So far, tool wear has been considered negligible when characterizing the machinability of green PM specimens. This inaccurate assumption may lead to the selection of suboptimum cutting conditions. The first part of this study involves the optimization of the machining parameters to minimize the effects of tool wear on the machinability in turning of green PM components. The second part of our work compares the sintered mechanical properties of components machined in green state with other machined after sintering.

The purpose of this study was to examine the outreach effort and impact of a joint federal-state campaign, Own Your Future, promoting awareness and planning for long-term care (LTC) in the state of Washington. The study applied survey methodology to evaluate the extent of campaign dissemination, evidence of its impact on LTC planning behaviors, and barriers to purchasing private LTC insurance. A total of 3,198 survey responses from a randomly selected community sample and a Washington State employee sample (ages 51 to 71) were analyzed. Results indicated that the impact of the campaign was limited, both with respect to awareness of the campaign itself and to initiation of LTC planning behaviors. Quantitative data revealed a high prevalence of health-related problems (e.g., obesity, diabetes), inadequate knowledge of basic LTC-related information (e.g., cost, payers), and negative attitudes toward purchasing LTC insurance among respondents. Qualitative analyses suggested that respondents perceived significant problems related to affordability and accountability within the current LTC insurance industry. These possible barriers to the purchase of LTC insurance suggest targets to be addressed by policy makers seeking to find ways to offset the public costs of LTC.

Extending overjustification: the effect of perceived reward-giver intention on response to rewards.

PubMed

Forehand, M R

2000-12-01

The perceived intention model incorporates a new moderator, beliefs about reward-giver intention, into the overjustification paradigm. In 2 simulated shopping studies featuring products paired with promotional rewards, consumers who believed the marketer was promotion focused (reward used to encourage purchase) reported lower purchase intentions and brand attitudes for promoted products after promotion, whereas consumers who believed the marketer was reward focused (promotion used to distribute the reward) showed no attitude change. Promotion-focus beliefs lowered attitudes by heightening the contingency between the promotion and purchase and thereby increasing the perceived causal role of the reward. This effect was contingent on initial behavior--postpromotion attitude change occurred for consumers who actively engaged in product decisions but not for consumers who passively observed the choice sets.

Background Young Australians aged between 18 and 30 years have experienced the largest increase in the body mass index and spend the largest proportion of their food budget on fast food and eating out. Frequent consumption of foods purchased and eaten away from home has been linked to poorer diet quality and weight gain. There has been no Australian research regarding quantities, type, or the frequency of consumption of food prepared outside the home by young adults and its impact on their energy and nutrient intakes. Objectives The objective of this study was to determine the relative contributions of different food outlets (eg, fast food chain, independent takeaway food store, coffee shop, etc) to the overall food and beverage intake of young adults; to assess the extent to which food and beverages consumed away from home contribute to young adults’ total energy and deleterious nutrient intakes; and to study social and physical environmental interactions with consumption patterns of young adults. Methods A cross-sectional study of 1008 young adults will be conducted. Individuals are eligible to participate if they: (1) are aged between 18 and 30 years; (2) reside in New South Wales, Australia; (3) own or have access to a smartphone; (4) are English-literate; and (5) consume at least one meal, snack, or drink purchased outside the home per week. An even spread of gender, age groups (18 to 24 years and 25 to 30 years), metropolitan or regional geographical areas, and high and low socioeconomic status areas will be included. Participants will record all food and drink consumed over 3 consecutive days, together with location purchased and consumed in our customized smartphone app named Eat and Track (EaT). Participants will then complete an extensive demographics questionnaire. Mean intakes of energy, nutrients, and food groups will be calculated along with the relative contribution of foods purchased and eaten away from home. A subsample of 19.84% (200/1008) of the participants will complete three 24-hour recall interviews to compare with the data collected using EaT. Data mining techniques such as clustering, decision trees, neural networks, and support vector machines will be used to build predictive models and identify important patterns. Results Recruitment is underway, and results will be available in 2018. Conclusions The contribution of foods prepared away from home, in terms of energy, nutrients, deleterious nutrients, and food groups to young people’s diets will be determined, as will the impact on meeting national recommendations. Foods and consumption behaviors that should be targeted in future health promotion efforts for young adults will be identified. PMID:29374002

Animal behavior has been studied for centuries, but few efficient methods are available to automatically identify and classify it. Quantitative behavioral studies have been hindered by the subjective and imprecise nature of human observation, and the slow speed of annotating behavioral data. Here, we developed an automatic behavior analysis pipeline for the cnidarian Hydra vulgaris using machine learning. We imaged freely behaving Hydra , extracted motion and shape features from the videos, and constructed a dictionary of visual features to classify pre-defined behaviors. We also identified unannotated behaviors with unsupervised methods. Using this analysis pipeline, we quantified 6 basic behaviors and found surprisingly similar behavior statistics across animals within the same species, regardless of experimental conditions. Our analysis indicates that the fundamental behavioral repertoire of Hydra is stable. This robustness could reflect a homeostatic neural control of "housekeeping" behaviors which could have been already present in the earliest nervous systems. © 2018, Han et al.

Effectiveness of subsidies in promoting healthy food purchases and consumption: a review of field experiments.

2013-07-01

To systematically review evidence from field interventions on the effectiveness of monetary subsidies in promoting healthier food purchases and consumption. Keyword and reference searches were conducted in five electronic databases: Cochrane Library, EconLit, MEDLINE, PsycINFO and Web of Science. Studies were included based on the following criteria: (i) intervention: field experiments; (ii) population: adolescents 12–17 years old or adults 18 years and older; (iii) design: randomized controlled trials, cohort studies or pre–post studies; (iv) subsidy: price discounts or vouchers for healthier foods; (v) outcome: food purchases or consumption; (vi) period: 1990–2012; and (vii) language: English. Twenty-four articles on twenty distinct experiments were included with study quality assessed using predefined methodological criteria. Interventions were conducted in seven countries: the USA (n 14), Canada (n 1), France (n 1), Germany (n 1), Netherlands (n 1), South Africa (n 1) and the UK (n 1). Subsidies applied to different types of foods such as fruits, vegetables and low-fat snacks sold in supermarkets, cafeterias, vending machines, farmers’ markets or restaurants. Interventions enrolled various population subgroups such as school/ university students, metropolitan transit workers and low-income women. All but one study found subsidies on healthier foods to significantly increase the purchase and consumption of promoted products. Study limitations include small and convenience samples, short intervention and follow-up duration, and lack of cost-effectiveness and overall diet assessment. Subsidizing healthier foods tends to be effective in modifying dietary behaviour. Future studies should examine its long-term effectiveness and cost-effectiveness at the population level and its impact on overall diet intake.

Evaluation of Fatigue Behavior and Surface Characteristics of Aluminum Alloy 2024 T6 After Electric Discharge Machining

2017-10-01

The effect of electric discharge machining (EDM) on surface quality and consequently on the fatigue performance of Al 2024 T6 is investigated. Five levels of discharge current are analyzed, while all other electrical and nonelectrical parameters are kept constant. At each discharge current level, dog-bone specimens are machined by generating a peripheral notch at the center. The fatigue tests are performed on four-point rotating bending machine at room temperature. For comparison purposes, fatigue tests are also performed on the conventionally machined specimens. Linearized SN curves for 95% failure probability and with four different confidence levels (75, 90, 95 and 99%) are plotted for each discharge current level as well as for conventionally machined specimens. These plots show that the electric discharge machined (EDMed) specimens give inferior fatigue behavior as compared to conventionally machined specimen. Moreover, discharge current inversely affects the fatigue life, and this influence is highly pronounced at lower stresses. The EDMed surfaces are characterized by surface properties that could be responsible for change in fatigue life such as surface morphology, surface roughness, white layer thickness, microhardness and residual stresses. It is found that all these surface properties are affected by changing discharge current level. However, change in fatigue life by discharge current could not be associated independently to any single surface property.

Information asymmetry, social networking site word of mouth, and mobility effects on social commerce in Korea.

The purpose of this research is to examine the issues that affect customers' behavioral character and purchasing behavior. The study proposes a research hypothesis with independent variables that include social presence, trust, and information asymmetry, and the dependent variable purchase decision making, to explain differentiated customer decision making processes in social commerce (S-commerce). To prove the hypothesis, positive verification was performed by focusing on mediating effects through a customer uncertainty variable and moderating effects through mobility and social networking site word of mouth (SNS WOM) variables. The number of studies on customer trends has rapidly increased together with the market size of S-commerce. However, few studies have examined the negative variables that make customers hesitant to make decisions in S-commerce. This study investigates the causes of customer uncertainty and focuses on deducing the control variables that offset this negative relationship. The study finds that in customers' S-commerce purchasing actions, the SNS WOM and mobility variables show control effects between information asymmetry and uncertainty and between trust and uncertainty. Additionally, this research defines the variables related to customer uncertainty that are hidden in S-commerce, and statistically verifies their relationship. The research results can be used in Internet marketing practices to establish marketing mix strategies for customer demand or as research data to predict customer behavior. The results are scientifically meaningful as a precedent for research on customers in S-commerce.

Tobacco taxes are one of the most effective policy interventions to reduce tobacco use. Tax avoidance, however, lessens the public health benefits of higher-priced cigarettes. Few studies examine responses to cigarette tax policies, particularly among high-risk minority populations. This study examined the prevalence and correlates of tax avoidance and changes in smoking behaviors among Chinese American smokers in New York City after a large tax increase. We conducted a cross-sectional study with data for 614 male smokers from in-person and telephone interviews using a comprehensive household-based survey of 2,537 adults aged 18-74 years. Interviews were conducted in multiple Chinese dialects. A total of 54.7% of respondents reported engaging in at least one low- or no-tax strategy after the New York City and New York State tax increases. The more common strategies for tax avoidance were purchasing cigarettes from a private supplier/importer and purchasing duty free/overseas. Higher consumption, younger age, and number of years in the U.S. were consistently associated with engaging in tax avoidance. Younger and heavier continuing smokers were less likely to make a change in smoking behavior in response to the tax increase. Despite high levels of tax avoidance and varying prices, nearly half of continuing smokers made a positive change in smoking behavior after the tax increase. Expanded legislation and enforcement must be directed toward minimizing the availability of legal and illegal low- or no-tax cigarette outlets. Public education and cessation assistance customized for the Chinese American community is key to maximizing the effectiveness of tobacco tax policies in this population.

Objectives To assess exposure to marketing of unhealthy food products and its relation to food related behavior and BMI in children aged 3–13, from different socioeconomic backgrounds in a south Indian town. Methods Child-parent pairs (n = 306) were recruited at pediatric clinics. Exposure to food marketing was assessed by a digital logo recognition test. Children matched 18 logos of unhealthy food (high in fat/sugar/salt) featured in promotion material from the food industry to pictures of corresponding products. Children's nutritional knowledge, food preferences, purchase requests, eating behavior and socioeconomic characteristics were assessed by a digital game and parental questionnaires. Anthropometric measurements were recorded. Results Recognition rates for the brand logos ranged from 30% to 80%. Logo recognition ability increased with age (p<0.001) and socioeconomic level (p<0.001 comparing children in the highest and lowest of three socioeconomic groups). Adjusted for gender, age and socioeconomic group, logo recognition was associated with higher BMI (p = 0.022) and nutritional knowledge (p<0.001) but not to unhealthy food preferences or purchase requests. Conclusions Children from higher socioeconomic groups in the region had higher brand logo recognition ability and are possibly exposed to more food marketing. The study did not lend support to a link between exposure to marketing and poor eating behavior, distorted nutritional knowledge or increased purchase requests. The correlation between logo recognition and BMI warrants further investigation on food marketing towards children and its potential role in the increasing burden of non-communicable diseases in this part of India.

This study describes the opinions and behaviors of chiropractic patients in a large, western Canadian urban center regarding the sale of health products by doctors of chiropractic. A brief, descriptive survey consisting of both fixed-choice and open-ended questions was distributed by clinic reception staff at 4 chiropractic offices in Calgary, Alberta, Canada. Each practice sold a range of health products, including those relating to musculoskeletal care and nutrition, and served between 275 and 320 clients per week. After a 10-week recruitment interval between January and March 2013, a convenience sample of 103 chiropractic patients was obtained. Most patients supported the sale of health products by doctors of chiropractic (n = 101; 98.1%), and most had made health product purchases from a doctor of chiropractic at some point (n = 73; 70.9%). Products relating to muscular care, exercise/rehabilitation products, and pillows were purchased most often (>40%). Consumers were most supportive of doctors of chiropractic selling products they perceived to be directly related to musculoskeletal care. Some participants believed that there should be limits placed on the range of products sold including the products had to be consistent with the practitioner's area of expertise and had to have some demonstrated level of effectiveness. Primary reasons for health product purchase included the doctor's recommendations, convenience, and perception that the product would improve well-being (>50%). This study found that chiropractic patients were supportive of health product sales by doctors of chiropractic, assuming certain conditions were met. Consumers believed that product sales should be undertaken with integrity and should be consistent with the doctor's area of expertise. Consumer beliefs appeared to impact their purchasing behaviors.

Bleidorn, Wiebke; Hopwood, Christopher James

2018-05-01

Machine learning has led to important advances in society. One of the most exciting applications of machine learning in psychological science has been the development of assessment tools that can powerfully predict human behavior and personality traits. Thus far, machine learning approaches to personality assessment have focused on the associations between social media and other digital records with established personality measures. The goal of this article is to expand the potential of machine learning approaches to personality assessment by embedding it in a more comprehensive construct validation framework. We review recent applications of machine learning to personality assessment, place machine learning research in the broader context of fundamental principles of construct validation, and provide recommendations for how to use machine learning to advance our understanding of personality.

Bramer, Lisa M.; Chatterjee, Samrat; Holmes, Aimee E.

Business intelligence problems are particularly challenging due to the use of large volume and high velocity data in attempts to model and explain complex underlying phenomena. Incremental machine learning based approaches for summarizing trends and identifying anomalous behavior are often desirable in such conditions to assist domain experts in characterizing their data. The overall goal of this research is to develop a machine learning algorithm that enables predictive analysis on streaming data, detects changes and anomalies in the data, and can evolve based on the dynamic behavior of the data. Commercial shipping transaction data for the U.S. is used tomore » develop and test a Naïve Bayes model that classifies several companies into lines of businesses and demonstrates an ability to predict when the behavior of these companies changes by venturing into other lines of businesses.« less

Hypothetical purchase tasks have advanced behavioral economic evaluations of demand by circumventing practical and ethical restrictions associated with delivering drug reinforcers to participants. Numerous studies examining the reliability and validity of purchase task methodology suggest that it is a valuable method for assessing demand that warrants continued use and evaluation. Within the literature examining purchase tasks, the alcohol purchase task (APT) has received the most investigation, and currently represents the most experimentally validated variant. However, inconsistencies in purchase task methodology between studies exist, even within APT studies, and, to date, none have assessed the influence of experimental economic constraints on responding. This study examined changes in Q0 (reported consumption when drinks are free), breakpoint (price that suppresses consumption), and α (rate of change in demand elasticity) in the presence of different hypothetical durations of access to alcohol in an APT. One hundred seventy-nine participants (94 males, 85 females) from Amazon Mechanical Turk completed 3 APTs that varied in the duration of time at a party (i.e., access to alcoholic beverages) as described in the APT instructions (i.e., vignette). The 3 durations included 5-hr (used by Murphy et al., 2013), 1-hr, and 9-hr time frames. We found that hypothetical duration of access was significantly related to Q0 and breakpoint at the individual level. Additionally, group-level mean α decreased significantly with increases in duration of access, thus indicating relatively higher demand for alcohol with longer durations of access. We discuss implications for conducting hypothetical purchase task research and alcohol misuse prevention efforts. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Toward quantifying the abuse liability of ultraviolet tanning: A behavioral economic approach to tanning addiction.

Many adults engage in ultraviolet indoor tanning despite evidence of its association with skin cancer. The constellation of behaviors associated with ultraviolet indoor tanning is analogous to that in other behavioral addictions. Despite a growing literature on ultraviolet indoor tanning as an addiction, there remains no consensus on how to identify ultraviolet indoor tanning addictive tendencies. The purpose of the present study was to translate a behavioral economic task more commonly used in substance abuse to quantify the "abuse liability" of ultraviolet indoor tanning, establish construct validity, and determine convergent validity with the most commonly used diagnostic tools for ultraviolet indoor tanning addiction (i.e., mCAGE and mDSM-IV-TR). We conducted a between-groups study using a novel hypothetical Tanning Purchase Task to quantify intensity and elasticity of ultraviolet indoor tanning demand and permit statistical comparisons with the mCAGE and mDSM-IV-TR. Results suggest that behavioral economic demand is related to ultraviolet indoor tanning addiction status and adequately discriminates between potential addicted individuals from nonaddicted individuals. Moreover, we provide evidence that the Tanning Purchase Task renders behavioral economic indicators that are relevant to public health research. The present findings are limited to two ultraviolet indoor tanning addiction tools and a relatively small sample of high-risk ultraviolet indoor tanning users; however, these pilot data demonstrate the potential for behavioral economic assessment tools as diagnostic and research aids in ultraviolet indoor tanning addiction studies. © 2016 Society for the Experimental Analysis of Behavior.

Nutritional labelling is advocated as a means to promote healthier food purchasing and consumption, including lower energy intake. Internationally, many different nutritional labelling schemes have been introduced. There is no consensus on whether such labelling is effective in promoting healthier behaviour. To assess the impact of nutritional labelling for food and non-alcoholic drinks on purchasing and consumption of healthier items. Our secondary objective was to explore possible effect moderators of nutritional labelling on purchasing and consumption. We searched 13 electronic databases including CENTRAL, MEDLINE and Embase to 26 April 2017. We also handsearched references and citations and sought unpublished studies through websites and trials registries. Eligible studies: were randomised or quasi-randomised controlled trials (RCTs/Q-RCTs), controlled before-and-after studies, or interrupted time series (ITS) studies; compared a labelled product (with information on nutrients or energy) with the same product without a nutritional label; assessed objectively measured purchasing or consumption of foods or non-alcoholic drinks in real-world or laboratory settings. Two authors independently selected studies for inclusion and extracted study data. We applied the Cochrane 'Risk of bias' tool and GRADE to assess the quality of evidence. We pooled studies that evaluated similar interventions and outcomes using a random-effects meta-analysis, and we synthesised data from other studies in a narrative summary. We included 28 studies, comprising 17 RCTs, 5 Q-RCTs and 6 ITS studies. Most (21/28) took place in the USA, and 19 took place in university settings, 14 of which mainly involved university students or staff. Most (20/28) studies assessed the impact of labelling on menus or menu boards, or nutritional labelling placed on, or adjacent to, a range of foods or drinks from which participants could choose. Eight studies provided participants with only one labelled food or drink option (in which labelling was present on a container or packaging, adjacent to the food or on a display board) and measured the amount consumed. The most frequently assessed labelling type was energy (i.e. calorie) information (12/28).Eleven studies assessed the impact of nutritional labelling on purchasing food or drink options in real-world settings, including purchases from vending machines (one cluster-RCT), grocery stores (one ITS), or restaurants, cafeterias or coffee shops (three RCTs, one Q-RCT and five ITS). Findings on vending machines and grocery stores were not interpretable, and were rated as very low quality. A meta-analysis of the three RCTs, all of which assessed energy labelling on menus in restaurants, demonstrated a statistically significant reduction of 47 kcal in energy purchased (MD -46.72 kcal, 95% CI -78.35, -15.10, N = 1877). Assuming an average meal of 600 kcal, energy labelling on menus would reduce energy purchased per meal by 7.8% (95% CI 2.5% to 13.1%). The quality of the evidence for these three studies was rated as low, so our confidence in the effect estimate is limited and may change with further studies. Of the remaining six studies, only two (both ITS studies involving energy labels on menus or menus boards in a coffee shop or cafeteria) were at low risk of bias, and their results support the meta-analysis. The results of the other four studies which were conducted in a restaurant, cafeterias (2 studies) or a coffee shop, were not clearly reported and were at high risk of bias.Seventeen studies assessed the impact of nutritional labels on consumption in artificial settings or scenarios (henceforth referred to as laboratory studies or settings). Of these, eight (all RCTs) assessed the effect of labels on menus or placed on a range of food options. A meta-analysis of these studies did not conclusively demonstrate a reduction in energy consumed during a meal (MD -50 kcal, 95% CI -104.41, 3.88, N = 1705). We rated the quality of the evidence as low, so our confidence in the effect estimate is limited and may change with further studies.Six laboratory studies (four RCTs and two Q-RCTs) assessed the impact of labelling a single food or drink option (such as chocolate, pasta or soft drinks) on energy consumed during a snack or meal. A meta-analysis of these studies did not demonstrate a statistically significant difference in energy (kcal) consumed (SMD 0.05, 95% CI -0.17 to 0.27, N = 732). However, the confidence intervals were wide, suggesting uncertainty in the true effect size. We rated the quality of the evidence as low, so our confidence in the effect estimate is limited and may change with further studies.There was no evidence that nutritional labelling had the unintended harm of increasing energy purchased or consumed. Indirect evidence came from five laboratory studies that involved mislabelling single nutrient content (i.e. placing low energy or low fat labels on high-energy foods) during a snack or meal. A meta-analysis of these studies did not demonstrate a statistically significant increase in energy (kcal) consumed (SMD 0.19, 95% CI -0.14to 0.51, N = 718). The effect was small and the confidence intervals wide, suggesting uncertainty in the true effect size. We rated the quality of the evidence from these studies as very low, providing very little confidence in the effect estimate. Findings from a small body of low-quality evidence suggest that nutritional labelling comprising energy information on menus may reduce energy purchased in restaurants. The evidence assessing the impact on consumption of energy information on menus or on a range of food options in laboratory settings suggests a similar effect to that observed for purchasing, although the evidence is less definite and also of low quality.Accordingly, and in the absence of observed harms, we tentatively suggest that nutritional labelling on menus in restaurants could be used as part of a wider set of measures to tackle obesity. Additional high-quality research in real-world settings is needed to enable more certain conclusions.Further high-quality research is also needed to address the dearth of evidence from grocery stores and vending machines and to assess potential moderators of the intervention effect, including socioeconomic status.

Application of a simple recording system to the analysis of free-play behavior in autistic children1

Boer, Arend P.

1968-01-01

An observational system, which has been developed to facilitate recording of the total behavioral repertoire of autistic children, involves time-sampling recording of behavior with the help of a common Stenograph machine. Categories which exhausted all behavior were defined. Each category corresponded with a designated key on the Stenograph machine. The observer depressed one key at each 1-sec interval. The observer was paced by audible beats from a metronome. A naive observer can be used with this method. The observer is not mechanically limited and a minimum of observer training is required to obtain reliable measures. The data sampled during a five-week observation period indicated the stability of a taxonomic instrument of behavior based upon direct, time-sampling observations and the stability of spontaneous autistic behavior. Results showed that the behavior of the subjects was largely nonrandom and unsocialized in character. PMID:16795193

2016-01-01

The advance of the Internet and new technologies over the last decade has transformed the retailing panorama. More and more channels are emerging, causing consumers to change their habits and shopping behavior. An omnichannel strategy is a form of retailing that, by enabling real interaction, allows customers to shop across channels anywhere and at any time, thereby providing them with a unique, complete, and seamless shopping experience that breaks down the barriers between channels. This paper aims to identify the factors that influence omnichannel consumers' behavior through their acceptance of and intention to use new technologies during the shopping process. To this end, an original model was developed to explain omnichannel shopping behavior based on the variables used in the UTAUT2 model and two additional factors: personal innovativeness and perceived security. The model was tested with a sample of 628 Spanish customers of the store Zara who had used at least two channels during their most recent shopping journey. The results indicate that the key determinants of purchase intention in an omnichannel context are, in order of importance: personal innovativeness, effort expectancy, and performance expectancy. The theoretical and managerial implications are discussed. PMID:27516749

The unwary purchaser: consumer psychology and the regulation of commerce in America.

PubMed

Pettit, Michael J

2007-01-01

Starting in the 1870s, American jurists deciding cases of trademark infringement began advancing arguments that the ordinary purchaser was an unwary one, easily deceived by imitations. Embedded within their legal decisions was a vision of the typical consumers' habitual behavior and cognitive ability. In response to legal critics who argued that the presumed psychology of the consumer was unevenly deployed, applied psychologists developed laboratory-based experiments and scales for determining the likelihood that the "average" purchaser would be confused. Although these psychologists failed in their goal of securing regular legal patronage, this commercial context and the resulting experiments were constitutive of the delineation of "recognition" as a distinct mental process. Furthermore, this case study complicates the scholarly consensus about the role of standardization and personal responsibility in the liberal administration of mass society.

As a kind of computer aided translation method, Interactive Machine Translation technology reduced manual translation repetitive and mechanical operation through a variety of methods, so as to get the translation efficiency, and played an important role in the practical application of the translation work. In this paper, we regarded the behavior of users' frequently searching for words in the translation process as the research object, and transformed the behavior to the translation selection problem under the current translation. The paper presented a prediction model, which is a comprehensive utilization of alignment model, translation model and language model of the searching words behavior. It achieved a highly accurate prediction of searching words behavior, and reduced the switching of mouse and keyboard operations in the users' translation process.

Objectives To investigate the impact of information on foodborne disease on consumers, we quantified consumers’ anxiety, purchasing behaviors, and willingness-to-pay (WTP) in response to the reading of newspaper articles published in 2001 that documented the first cow in Japan to be infected with bovine spongiform encephalopathy (BSE). Methods An online questionnaire survey of 993 females aged 20–59 years was conducted in 2007. The participants were randomly selected from the general population via the Internet and were divided into three groups. Each group was assigned a different number of BSE-related articles to read, namely, two, four, and six articles, respectively. Each participant described her personal level of anxiety, underlying reasons for her anxiety, and changes in purchasing behavior after reading the articles. The respondents who wanted to buy guaranteed-safe beef were asked to state their maximal WTP. Results The level of anxiety was significantly lower and distrust of the relevant administration significantly greater in the group asked to read six articles than in the other groups. The WTP value for guaranteed beef was approximately 1.3-fold higher than the regular purchase price, with significant differences between groups. In the ‘six-article’ group, the ratio between WTP and the regular purchase price was significantly less than that in the ‘four-article’ group. Conclusions These findings suggest that the anxiety of consumers can be reduced if they receive an appropriate amount of published information. WTP may be linked to the contents of the articles.

To test the feasibility and effectiveness of social marketing on the improvement of women's knowledge, attitudes, and behaviors regarding iron-fortified soy sauce (FeSS). A community-based intervention was conducted among 4 groups, experimental rural (E(R)), control rural (C(R)), experimental urban (E(U)), and control urban (C(U)). Urban and rural areas in Guizhou province, China. Women 19 to 70 years old (n = 193 in rural areas and n = 179 in urban areas). A mass-media campaign to promote use of FeSS was conducted throughout Guizhou province. In the intervention areas, social marketing strategies using integrated 6 Ps (product, price, place, promotion, policy, and partnership) were implemented from December 2004 to February 2006. Knowledge of FeSS; benefits, barriers, and intention to purchase; availability of FeSS; behaviors regarding purchase and use of FeSS. Analysis of covariance, paired T test and cross-tabulations were used. The alpha level was set at .05. Compared with the baseline, perceived benefits of FeSS, barriers (BARRI) and intention to buy (INTEN) significantly improved within both experimental groups (P < .01 or .001). The only improvement in control groups was for BARRI in C(R) (P < .001). Availability of FeSS increased in all areas. Purchase and use of FeSS in rural and urban intervention groups increased by nearly 30% more than those in control groups. Social marketing of FeSS is feasible and effective to improve knowledge, perception (perceived benefits and overcoming barriers), intention to purchase, and consumption of FeSS among women in Guizhou, China.

Latent factor structure of a behavioral economic marijuana demand curve.

Drug demand, or relative value, can be assessed via analysis of behavioral economic purchase task performance. Five demand indices are typically obtained from drug purchase tasks. The goal of this research was to determine whether metrics of marijuana reinforcement from a marijuana purchase task (MPT) exhibit a latent factor structure that efficiently characterizes marijuana demand. Participants were regular marijuana users (n = 99; 37.4% female, 71.5% marijuana use days [5 days/week], 15.2% cannabis dependent) who completed study assessments, including the MPT, during a baseline session. Principal component analysis was used to examine the latent structure underlying MPT indices. Concurrent validity was assessed via examination of relationships between latent factors and marijuana use, past quit attempts, and marijuana expectancies. A two-factor solution was confirmed as the best fitting structure, accounting for 88.5% of the overall variance. Factor 1 (65.8% variance) reflected "Persistence," indicating sensitivity to escalating marijuana price, which comprised four MPT indices (elasticity, O max , P max , and breakpoint). Factor 2 (22.7% variance) reflected "Amplitude," indicating the amount consumed at unrestricted price (intensity). Persistence factor scores were associated with fewer past marijuana quit attempts and lower expectancies of negative use outcomes. Amplitude factor scores were associated with more frequent use, dependence symptoms, craving severity, and positive marijuana outcome expectancies. Consistent with research on alcohol and cigarette purchase tasks, the MPT can be characterized with a latent two-factor structure. Thus, demand for marijuana appears to encompass distinct dimensions of price sensitivity and volumetric consumption, with differential relations to other aspects of marijuana motivation.

Point-of-purchase nutrition information influences food-purchasing behaviors of college students: a pilot study.

Freedman, Marjorie R; Connors, Rachel

2010-08-01

The goal of point-of-purchase (POP) nutrition information is to help consumers make informed, healthful choices. Despite limited evaluation, these population-based approaches are being advocated to replace traditional, more expensive, individual behavior-change strategies. Few studies have examined the effect of POP information on buying patterns of college students, a group with high obesity rates and poor eating habits. This quasi-experimental pilot project sought to determine whether the "Eat Smart" POP program affected food-purchasing habits of multiethnic college students shopping at an on-campus convenience store. Baseline sales data of foods in the cereal, soup, cracker, and bread categories were collected for 6 weeks during Fall 2008. After Winter break, a few food items within each of these food categories were labeled as healthful using a "Fuel Your Life" shelf tag, and sales data were then collected for 5 weeks. In each of the four food categories, nontagged foods were available at the identical price as tagged items. Following intervention, there were increased sales of tagged items (measured as a percentage of total sales) in the cereal, soup, and cracker categories, while sales of bread decreased. Although none of these changes were statistically significant, the intervention resulted in a 3.6%+/-1.6% (P=0.082) increase in the percentage of sales from tagged items. Thus, providing POP nutrition information in a college campus convenience store may promote healthful food choices. A longer study examining the effect of POP on sales of items in other food categories is warranted. 2010 American Dietetic Association. Published by Elsevier Inc. All rights reserved.

Sex purchasing and associations with HIV/STI among a clinic-based sample of US men.

Despite high rates of human immunodeficiency virus/sexually transmitted infection (HIV/STI) among commercial sex workers and international concern that male clients may constitute a critical bridge population for HIV/STI transmission, little empirical data exist within the United States to characterize men who purchase sex or to assess their sexual risk and HIV/STI infection. The study involves the analysis of a community-based survey of men aged 18-35 years attending urban health centers (n=1515) to assess the prevalence of engagement in sex purchasing during the past year and to evaluate relations with self-reported HIV/STI diagnosis and symptoms across this same period. More than 1 in 12 (8.7%) men reported exchanging drugs, money, or a place to stay for sex with a female partner in the past year. Such behavior was associated with additional sexual risk taking and emerged as an independent predictor of self-reported HIV/STI diagnosis [adjusted odds ratio (ORadj)=2.99; 95% confidence interval (CI): 1.51 to 5.94] and STI symptoms (ORadj=2.57; 95% CI: 1.57 to 4.22) in the past year in analyses adjusted for alternate HIV/STI risk sources. Sex purchasing is a common form of HIV/STI risk among the population sampled. Men engaging in such behavior are more likely to be HIV/STI infected and, thus, represent a risk to the sexual health of both commercial and noncommercial sex partners. Further research is needed to inform interventions targeted toward male clients of prostituted women.

Studies have revealed that consumers are susceptible to price framing effect, a common cognitive bias, due to their limited capacity in processing information. The effect of price framing in a bundling context and its neural correlates, however, remain not clearly characterized. The present study applied the event-related potentials (ERPs) approach to investigate the role of price framing in information processing and purchase decision making in a bundling context. Three price frames were created with practically identical total prices (with a maximum difference of ¥0.1, which was about equal to 0.016 US dollars) for a bundle with two components, a focal product and a tie-in product. In normal price condition (NP), both the focal and tie-in products were offered at a normal discounted price; in zero price condition (ZP), the tie-in product was offered free while the total price of the bundle remained the same as NP; whereas in low price condition (LP), the tie-in product was offered at a low token price (¥0.1), and the focal product shared the same price as the focal product of ZP. The behavioral results showed a higher purchase rate and a shorter reaction time for ZP in contrast to NP. Neurophysiologically, enlarged LPP amplitude was elicited by ZP relative to NP, suggesting that ZP triggered a stronger positive affect that could motivate decision to buy. Thus, this study provides both behavioral and neural evidence for how different price framing information is processed and ultimately gives rise to price framing effect in purchase decision making.

Binary classification of aqueous solubility using support vector machines with reduction and recombination feature selection.

2011-02-28

Aqueous solubility is recognized as a critical parameter in both the early- and late-stage drug discovery. Therefore, in silico modeling of solubility has attracted extensive interests in recent years. Most previous studies have been limited in using relatively small data sets with limited diversity, which in turn limits the predictability of derived models. In this work, we present a support vector machines model for the binary classification of solubility by taking advantage of the largest known public data set that contains over 46 000 compounds with experimental solubility. Our model was optimized in combination with a reduction and recombination feature selection strategy. The best model demonstrated robust performance in both cross-validation and prediction of two independent test sets, indicating it could be a practical tool to select soluble compounds for screening, purchasing, and synthesizing. Moreover, our work may be used for comparative evaluation of solubility classification studies ascribe to the use of completely public resources.

Post-purchase reassessment and improvement of neuroendoscope holder: importance of physician-manufacturer communication.

PubMed

Ogawa, Yoshikazu; Nakata, Yusuke; Tominaga, Teiji

2014-01-01

Modern medical management requires constant quality improvement of the various instruments used for surgical procedures. Higher quality, less complicated handling, and reduced maintenance are all desirable qualities. However, any improvements in instrumentation require that surgeons must clearly understand the application of the device by adherence to the manufacturer's instructions. The weakness of this one-way information flow depends on the low interest among medical personnel for post-purchase reassessment. Service industries have research departments to investigate the post-purchase behavior of customers, and service recovery is considered essential to retain customers after service failure. All service providers can suffer service failures, and even the best providers may make errors in delivering service. Such an approach has been increasingly adopted in the risk management at medical institutions. We report our clinical trials of the post-purchase reassessment and product improvement of surgical instrumentation. Medical personnel reassessed the use of a newly developed endoscope holder based on the manufacturer's manual and made recommendations for possible improvements, which were examined by the manufacturer. Simple but important improvement was achieved for reducing the instability and uncertainty of instrument fixation. This bi-directional post-purchase communication between medical personnel and manufacturers can improve risk management in medical institutions.

How state taxes and policies targeting soda consumption modify the association between school vending machines and student dietary behaviors: a cross-sectional analysis.

Sodas are widely sold in vending machines and other school venues in the United States, particularly in high school. Research suggests that policy changes have reduced soda access, but the impact of reduced access on consumption is unclear. This study was designed to identify student, environmental, or policy characteristics that modify the associations between school vending machines and student dietary behaviors. Data on school vending machine access and student diet were obtained as part of the National Youth Physical Activity and Nutrition Study (NYPANS) and linked to state-level data on soda taxes, restaurant taxes, and state laws governing the sale of soda in schools. Regression models were used to: 1) estimate associations between vending machine access and soda consumption, fast food consumption, and lunch source, and 2) determine if associations were modified by state soda taxes, restaurant taxes, laws banning in-school soda sales, or student characteristics (race/ethnicity, sex, home food access, weight loss behaviors.). Contrary to the hypothesis, students tended to consume 0.53 fewer servings of soda/week (95% CI: -1.17, 0.11) and consume fast food on 0.24 fewer days/week (95% CI: -0.44, -0.05) if they had in-school access to vending machines. They were also less likely to consume soda daily (23.9% vs. 27.9%, average difference  =  -4.02, 95% CI: -7.28, -0.76). However, these inverse associations were observed primarily among states with lower soda and restaurant tax rates (relative to general food tax rates) and states that did not ban in-school soda sales. Associations did not vary by any student characteristics except for weight loss behaviors. Isolated changes to the school food environment may have unintended consequences unless policymakers incorporate other initiatives designed to discourage overall soda consumption.

Background Sodas are widely sold in vending machines and other school venues in the United States, particularly in high school. Research suggests that policy changes have reduced soda access, but the impact of reduced access on consumption is unclear. This study was designed to identify student, environmental, or policy characteristics that modify the associations between school vending machines and student dietary behaviors. Methods Data on school vending machine access and student diet were obtained as part of the National Youth Physical Activity and Nutrition Study (NYPANS) and linked to state-level data on soda taxes, restaurant taxes, and state laws governing the sale of soda in schools.

They were also less likely to consume soda daily (23.9% vs. 27.9%, average difference = -4.02, 95% CI: -7.28, -0.76). However, these inverse associations were observed primarily among states with lower soda and restaurant tax rates (relative to general food tax rates) and states that did not ban in-school soda sales.

2010-01-01

A study has been performed to investigate the effect of various machining processes on fatigue life of configured low cycle fatigue specimens machined out of a NASA developed LSHR P/M nickel based disk alloy. Two types of configured specimen geometries were employed in the study. To evaluate a broach machining processes a double notch geometry was used with both notches machined using broach tooling. EDM machined notched specimens of the same configuration were tested for comparison purposes. Honing finishing process was evaluated by using a center hole specimen geometry. Comparison testing was again done using EDM machined specimens of the same geometry. The effect of these machining processes on the resulting surface roughness, residual stress distribution and microstructural damage were characterized and used in attempt to explain the low cycle fatigue results.

Foxall, G R

1998-01-01

This article considers an approach to the radical behaviorist interpretation of complex human social behavior. The chosen context is consumer psychology, a field currently dominated by cognitive models of purchase and consumption. The nature of operant interpretation is considered, and several levels of operant analysis of complex economic behavior in affluent marketing-oriented economies are developed. Empirical evidence for the interpretation is considered, and a case is made for the qualified use of the hypothetico-deductive method in the appraisal of operant interpretations of complex behaviors.

To investigate reasons why parents purchase prepackaged, processed meals and associations with parental cooking self-efficacy, meal-planning ability, and home food availability. This secondary data analysis uses Healthy Home Offerings via the Mealtime Environment Plus study data from parents of children aged 8-12 years (n = 160). Associations between reasons why parents purchase prepackaged, processed meals and the outcomes were assessed with chi-square, Fisher exact, and t tests. The most frequently endorsed reasons for purchasing prepackaged, processed meals included lack of time (57%) and family preferences (49%). Five of 6 reasons were associated with lower parental cooking self-efficacy and meal-planning ability. Some reasons were associated with less-healthful home food environments; few reasons varied by socio-demographic characteristics. Because lower cooking self-efficacy and meal-planning ability are associated with most reasons reported for purchasing prepackaged, processed meals, strategies to increase these attributes for parents of all backgrounds may reduce reliance on prepackaged processed meals for family mealtimes.

Determinants of the intention to purchase an autochthonous local lamb breed: Spanish case study.

PubMed

Gracia, Azucena; Maza, María Teresa

2015-12-01

The aim of the paper is to study consumers' acceptability for a lamb meat from a local autochthonous breed. An intention to purchase model was developed based on the Theory of Planned Behavior (TPB) and estimated using data from a survey conducted in Spain. Results indicated that consumers were willing to buy this lamb meat because 86% of respondents said that they probably/definitely would buy it, although only 23% would if the meat is not available in their usual meat store. Then, the lack of availability in the market is an aspect limiting its consumption. The most important factors explaining the intention to purchase for consumers who would purchase this meat if it were not available in their usual store are the importance attached to the animal breed and their social embeddedness with the local area. An appropriate food policy would be to inform consumers about the importance of the animal breed in the quality of the meat and the local origin. Copyright © 2015 Elsevier Ltd. All rights reserved.

What teenagers and young adults have to say about condoms and using condoms.

PubMed

Patient, D R; Orr, N M

2000-01-01

This study examined the perceptions of teenagers and young adults on condoms and condom use. By using two focus group sessions, 88 teenagers and young adults from South Africa were interviewed about their attitudes towards using condoms. The findings indicated that issues of image outweigh issues of risks in these groups. In obtaining condoms, these young adults did not trust free condoms and usually preferred anonymous points of purchase such as vending machines, which were also accessible at sites where they gathered for entertainment and socializing. In addition, the types of condoms available in the market were found to be unsuitable for these groups. Complaints on the color and size were noted, as well as the label of using condoms as boring and clinical. Lastly, to overcome the antipathy of using condoms, the paper suggests the following: development of black condoms, change of clinic and pharmacy staff attitude towards condom purchase, accessible distribution of condoms, and presentation of the product in such a way that it focuses on the fun aspect and less upon the clinical aspects.

There is growing interest in the usefulness of the workplace as a site for promotion of healthful food choices. The authors therefore analyzed data of U.S. adults (N = 1,918) who reported working outside the home and eating lunch. The majority (84.0%) of workers had a break room. About one half (54.0%) purchased lunch > or = 2 times/week, with higher percentages for males, Blacks, younger (age 18-34 years) versus older adults (age 55 years or older), and obese versus normal-weight persons. The most important lunch food choice value was convenience (34.3%), followed by taste (27.8%), cost (20.8%), and health (17.1%). The typical source for purchasing lunch was a fast-food restaurant (43.4%), followed by on-site cafeteria/snack shop (25.3%), full-service restaurant (16.9%), supermarket (5.2%), vending machine (4.4%), and convenience store (4.0%); younger adults and those less educated relied more on fast-food places. This study identifies individual factors and values that may influence future dietary health initiatives in the work site.

Grocery stores represent a context in which a majority of people's food purchases occur. Considering the nutrition quality of the population's food intake has dramatically decreased, understanding how to improve food choice in the grocery store is paramount to healthier living. In this work, we detail the type of financial resources from which shoppers could draw (i.e., personal income and benefits from government food assistance programs to low income populations) and explain how these financial resources are allocated in the grocery store (i.e., planned, unplanned, error). Subsequently, we identify a conceptual framework for shopper marketing nutrition interventions that targets unplanned fruit and vegetable purchases (i.e., slack, or willingness to spend minus list items). Targeting slack for fresh fruit and vegetable purchases allows retailers to benefit economically (i.e., fruit and vegetables are higher margin) and allows shoppers to improve their nutrition without increasing their budgets (i.e., budget neutrality). We also provide preliminary evidence of what in-store marketing of fresh fruits and vegetables could entail by modifying grocery carts and grocery floors to provide information of what is common, normal, or appropriate fruit and vegetable purchases. In each example, fresh fruit and vegetable purchases increased and evidence suggested shopper budget neutrality. To provide context for these results, we detail measurement tools that can be used to measure shopper behaviors, purchases, and consumption patterns. Finally, we address theoretical, practical, and policy implications of shopper marketing nutrition interventions. Copyright © 2014 Elsevier Inc. All rights reserved.

Behavioral economic measures of demand provide estimates of tobacco product abuse liability and may predict effects of policy-related price regulation on consumption of existing and emerging tobacco products. In the present study, we examined demand for snus, a smokeless tobacco product, in comparison to both cigarettes and medicinal nicotine. We used both a naturalistic method in which participants purchased these products for use outside the laboratory, as well as laboratory-based self-administration procedures. Cigarette smokers (N = 42) used an experimental income to purchase their usual brand of cigarettes and either snus or gum (only one product available per session) across a range of prices, while receiving all products they purchased from one randomly selected price. In a separate portion of the study, participants self-administered these products during laboratory-based, progressive ratio sessions. Demand elasticity (sensitivity of purchasing to price) was significantly greater for snus than cigarettes. Elasticity for gum was intermediate between snus and cigarettes but was not significantly different than either. Demand intensity (purchasing unconstrained by price) was significantly lower for gum compared to cigarettes, with no significant difference observed between snus and cigarettes. Results of the laboratory-based, progressive ratio sessions were generally discordant with measures of demand elasticity, with significantly higher "breakpoints" for cigarettes compared to gum and no significant differences between other study products. Moreover, breakpoints and product purchasing were generally uncorrelated across tasks. Under naturalistic conditions, snus appears more sensitive to price manipulation than either cigarettes or nicotine gum in existing smokers.

This paper examines how price minimizing behaviors impact efforts to stop smoking. Data on 4,988 participants from the International Tobacco Control Policy Evaluation (ITC) Four-Country Survey who were smokers at baseline (wave 5) and interviewed at a 1 year follow-up were used. We examined whether price minimizing behaviors at baseline predicted: (1) cessation, (2) quit attempts, and (3) successful quit attempts at one year follow up using multivariate logistic regression modeling. A subset analysis included 3,387 participants who were current smokers at waves 5 and 6 and were followed through wave 7 to explore effects of changing purchase patterns on cessation. Statistical tests for interaction were performed to examine the joint effect of SES and price/tax avoidance behaviors on cessation outcomes. Smokers who engaged in any price/tax avoidance behaviors were 28% less likely to report cessation. Persons using low/untaxed sources were less likely to quit at follow up, those purchasing cartons were less likely to make quit attempts and quit, and those using discount cigarettes were less likely to succeed, conditional on making attempts. Respondents who utilized multiple behaviors simultaneously were less likely to make quit attempts and to succeed. SES did not modify the effects of price minimizing behaviors on cessation outcomes. The data from this paper indicate that the availability of lower priced cigarette alternatives may attenuate public health efforts aimed at to reduce reducing smoking prevalence through price and tax increases among all SES groups.

Cost effective aluminum beryllium mirrors for critical optics applications

The unique performance of aluminum-beryllium frequently makes it an ideal material for manufacturing precision optical-grade metal mirrors. Traditional methods of manufacture utilize hot-pressed powder block in billet form which is subsequently machined to final dimensions. Complex component geometries such as lightweighted, non-plano mirrors require extensive tool path programming, fixturing, and CNC machining time and result in a high buy-to-fly ratio (the ratio of the mass of raw material purchased to the mass of the finished part). This increases the cost of the mirror structure as a significant percentage of the procurement cost is consumed in the form of machining, tooling, and scrap material that do not add value to the final part. Inrad Optics, Inc. and IBC Advanced Alloys Corp. undertook a joint study to evaluate the suitability of investment-cast Beralcast® 191 and 363 aluminum-beryllium as a precision mirror substrate material. Net shape investment castings of the desired geometry minimizes machining to just cleanup stock, thereby reducing the recurring procurement cost while still maintaining performance. The thermal stability of two mirrors, (one each of Beralcast® 191 and Beralcast® 363), was characterized from -40°F to +150°F. A representative pocketed mirror was developed, including the creation of a relevant geometry and production of a cast component to validate the approach. Information from the demonstration unit was used as a basis for a comparative cost study of the representative mirror produced in Beralcast® and one machined from a billet of AlBeMet® 162 (AlBeMet® is a registered trademark of Materion Corporation). The technical and financial results of these studies will be discussed in detail.

Tobler, Christina; Visschers, Vivianne H M; Siegrist, Michael

Food consumption is associated with various environmental impacts, and consumers' food choices therefore represent important environmental decisions. In a large-scale survey, we examined consumers' beliefs about ecological food consumption and their willingness to adopt such behaviors. Additionally, we investigated in more detail how different motives and food-related attitudes influenced consumers' willingness to reduce meat consumption and to buy seasonal fruits and vegetables. We found consumers believed avoiding excessive packaging had the strongest impact on the environment, whereas they rated purchasing organic food and reducing meat consumption as least environmentally beneficial. Similarly, respondents appeared to be most unwilling to reduce meat consumption and purchase organic food. Taste and environmental motives influenced consumers' willingness to eat seasonal fruits and vegetables, whereas preparedness to reduce meat consumption was influenced by health and ethical motives. Women and respondents who preferred natural foods were more willing to adopt ecological food consumption patterns. Copyright © 2011 Elsevier Ltd. All rights reserved.
