Consumer food waste behaviour in universities: Sharing as a means of prevention

In order to tackle food waste at the prevention stage of the waste hierarchy, an understanding of behaviour that leads to wastage is required. This article examines consumer food waste behaviour in a university setting and the implications for encouraging sharing as a means of mitigating food waste. The embodied and embedded nature of consumption and wasteful behaviours are contended, giving explanation to the transition of food into waste. By undertaking a mixed‐method study and a social media‐based intervention, behaviour that causes food to be wasted within a campus environment is discussed, furthering the current domestic focus of research. The paper argues that consumer food waste behaviour can be better understood by focusing on the practices, routines and habits of consumers given the hidden nature of the food waste issue. A number of barriers are also presented regarding the sharing of food as a means of food waste prevention. Copyright © 2016 John Wiley & Sons, Ltd.     

Mechanisms of behavioural maintenance: Long-term effects of theory-based interventions to promote safe water consumption

Theory-based interventions can enhance people’s safe water consumption, but the sustainability of these interventions and the mechanisms of maintenance remain unclear. We investigated these questions based on an extended theory of planned behaviour. Seven hundred and ten (445 analysed) randomly selected households participated in two cluster-randomised controlled trials in Bangladesh. Study 1 promoted switching to neighbours’ arsenic-safe wells, and Study 2 promoted switching to arsenic-safe deep wells. Both studies included two intervention phases. Structured interviews were conducted at baseline (T1), and at 1-month (T2), 2-month (T3) and 9-month (T4) follow-ups. In intervention phase 1 (between T1 and T2), commitment-based behaviour change techniques – reminders, implementation intentions and public commitment – were combined with information and compared to an information-only control group. In phase 2 (between T2 and T3), half of each phase 1 intervention group was randomly assigned to receive either commitment-based techniques once more or coping planning with reminders and information. Initial well-switching rates of up to 60% significantly declined by T4: 38.3% of T2 safe water users stopped consuming arsenic-safe water. The decline depended on the intervention. Perceived behavioural control, intentions, commitment strength and coping planning were associated with maintenance. In line with previous studies, the results indicate that commitment and reminders engender long-term behavioural change.

Sex differences in adolescent ethanol drinking to behavioral intoxication

Rodent models have been especially useful for investigating adolescent ethanol exposure. However, there is a paucity of studies examining sex differences in behavioral intoxication from adolescent ethanol drinking. Here, we used an ethanol drinking model to investigate if adolescent rats of both sexes readily drink ethanol to measurable behavioral intoxication, indicated by increased impulsive action and motor incoordination. Beginning on postnatal day (P) 28, male and female Long‐Evans rats were given 30‐min access to a solution of sucrose (20%) or sweetened ethanol (20% sucrose +15% ethanol) every other day until P60 and once after 2 weeks of forced abstinence (on P75). On alternate (nondrinking) days, rats were reinforced with a food pellet for making a cued nosepoke response. Beginning on P56, rats were tested in this task after drinking sessions to assess ethanol‐induced changes in impulsive action, defined as premature responding prior to cue presentation. Motor coordination was assessed before and after drinking sessions using an incline plane test. Adolescent male and female rats readily consumed ethanol to behavioral intoxication, measured as reduced motor coordination. Following forced abstinence, females displayed greater ethanol‐induced impulsive action. These studies provide evidence for sex differences in behavioral intoxication following adolescent ethanol drinking.     

The Theory of Emotions in Marketing

To determine whether a theory of emotions in marketing is needed, this article assesses the current theoretical status of emotions in marketing. The theoretical propositions and the characteristics of four major theories of emotions borrowed from psychology, as well as five marketing accounts for emotions are reviewed. The characteristics of emotions in marketing are specified and compared with the characteristics of emotions as seen by psychology. The article ends with four theoretical proposals on directions for future development of a theory of emotions in marketing.     

Local Food Environments: They’re All Stocked Differently

The obesity epidemic has widened the aims of prevention research to include the influence of local food environments on health outcomes. This mixed methods study extends existing research focused on local food environments by examining whether community members’ find food accessible. Data from food store audits and one-on-one interviews were analyzed. Results reveal that most of the food stores surrounding the three research sites were convenience stores and non-chain grocery stores; interviewees did not perceive these stores to be “real” food stores. Tobacco and alcohol products were more prevalent in the food stores than all varieties of milk, fresh fruits, or fresh vegetables. Food access varied by site in a manner that was designed to appeal to customers’ race, class, gender, or environment. Findings reveal that local food environments are reflections of social hierarchies. Unraveling the politics of space ought to be a part of broader efforts to promote the public’s health.     

When Sharing Is Not Caring: Does (un)Certainty About Bill Payment Method Lead Diners to Consume More and Spend More Money?

Previous work has demonstrated that unacquainted participants in an experimental, restaurant‐like setting consume more when they know in advance that the bill will be split evenly rather than paid according to individual consumption. Real life, however, often differs from these experimental settings in two important ways. First, unlike random groups of participants, diners who eat together are frequently friends or colleagues. Second, payment method (even vs. individual payment) is usually unknown (i.e. uncertain) at the time people place their orders, and is determined when the check arrives. The current research tests the ecological validity of the association between consumption amount and payment method. Study 1 was conducted in a natural setting with organic groups of diners. Some were asked to state their desired payment method before ordering (Certain condition); others did so only after asking for the check (Uncertain condition). In both conditions, even payment (as opposed to individual payment) was associated with greater consumption amount. However, overall, consumption amount was lower among diners in the Uncertain condition than among those in the Certain condition. Study 2 presents a controlled follow‐up experiment showing that eliminating diners' prior expectations regarding the payment method—by informing them that the payment method will be randomly determined after the consumption decision—eliminates the relationship between payment method and consumption amount. This study further indicates that when diners are uncertain what the payment method will be, even bill‐splitting has negative implications for their subsequent social interactions, expressed in retribution tendencies.

High dose alcohol consumption predicts less reduction in post-traumatic stress symptoms after a campus mass shooting

Background: Recognizing that alcohol might affect subsequent processing of trauma-related information, this study examined whether high dose alcohol consumption (HDAC) following a campus mass shooting affected the relation between shooting exposure and post-traumatic stress symptoms (PTSS).

Methods: Female participants (N?=?691) recorded levels of physical exposure to the shooting event, alcohol use, and PTSS 1 month following the shooting event and 8 months later.

Results: No evidence was found to suggest that pre-shooting HDAC moderated the relationship between trauma exposure and PTSS 1 month following the shooting. HDAC in the month following the shooting predicted less resolution of PTSS 8 months later. Specifically, at higher (but not lower) levels of HDAC, shooting exposure was associated with less reduction in PTSS from 1 to 8 months post-trauma. Several alternate explanations were ruled out.

Conclusions: Less reduction in PTSS seems to occur at high levels of both shooting exposure and HDAC. Theoretical implications and directions for future research are discussed.     

Need for uniqueness as a mediator of the relationship between face consciousness and status consumption in China

Strong economic development in China has led to a surge in status consumption as a means of gaining face. In Eastern culture, people interpret uniqueness as status distinction rather than separateness or deviance. This type of uniqueness can be used to meet others' expectations and gain social approval. Thus its relationship with face consciousness and status consumption is to be expected. This study investigates 2 hypotheses: (a) Face consciousness has a positive effect on status consumption and (b) Consumer need for uniqueness mediates the relationship between face consciousness and status consumption. Two‐hundred and forty‐six working respondents in eastern China completed a survey. Regression analysis of the results supported both hypotheses.     

Human Energy Expenditure and Postural Coordination on the Mechanical Horse

The authors investigated and compared the energy expenditure and postural coordination of two groups of healthy subjects on a mechanical horse at 4 increasing oscillation frequencies. Energy expenditure was assessed from the oxygen consumption, respiratory quotient, and heart rate values, and postural coordination was characterized by relative phase computations between subjects (elbow, head, trunk) and horse. The results showed that the postural coordination of the riders was better adapted (i.e., maintenance of in-phase and antiphase) than that of the nonriders, but the energy expenditure remains the same. Likewise, we observed an energy system shifting only for nonriders (from aerobic to lactic anaerobic mode). Finally, cross-correlations showed a link between energy expenditure and postural coordination in the riders (i.e., effectiveness).
