The Tortilla Curtain: War on the Table of the Poor

Abstract :  This essay approaches the concept of borders from a geopolitical perspective, focusing particularly on the dividing curtain between the USA and Mexico. Corn serves not only as Ariadne's thread but also as a symbol of food in general, to be problematized and not taken for granted. The author highlights God's imperative for us to take the side of the poor: to satiate their hunger and quench their thirst. This stands in clear contradiction to the current evil economic system that has reduced food to a weapon of mass destruction, through the simultaneous overproduction of food and hunger.     

WHY WE NEED RELIGION TO SOLVE THE WORLD FOOD CRISIS

Scholars and practitioners addressing the global food crisis have rarely incorporated perspectives from the world's religious traditions. This lacuna appears in multiple dimensions: until recently, environmentalists have tended to ignore food and agriculture; food justice advocates have focused on food quantities, rather than its method of production; and few scholars of religion have considered agriculture. Faith‐based perspectives typically emphasize the dignity and sanctity of creation and offer holistic frameworks that integrate equity, economic, and environmental concerns, often called the three legs of sustainability. Faith‐based perspectives can provide new paradigms through which to assess food, consumption, and production and the attendant social relations; assess our scientific, economic, and social approaches; and acknowledge the moral and religious dimensions of the world food crisis.     

Health-related behavioural change—a test of a new model

Abstract

Numerous studies have demonstrated that planned health education and health promotion interventions are not particularly successful in bringing about behavioural change. It is suggested that the reasons for this are the fallacious theoretical assumptions underlying many intervention strategies and the failure to place sufficient emphasis on the context in which health-related behaviours occur. Studies of self-initiated behavioural change suggest that the antecedents of change are often events or processes which bring a previously routinised and unremarked behaviour into new focus.

This paper describes a preliminary test of a new model of behavioural change in which a group of lay people were recruited to act as paid interviewers on a food survey in their own area. The survey was particularly concerned with the consumption of high fibre foods. he and post-test measures of the interviewers' own food habits as compared with those of a control group indicated modest support for the proposed model. Implications of this study for health education and promotion are discussed.     

Locating Religion in the Context of Charitable Food Assistance: An Ethnographic Study of Food Banks in a Finnish City

This article explores how, for whom, and to what extent religion is part of the reality that people enter into as they seek food assistance from a religious organization. Drawing from an ethnographic study of food assistance places in a Finnish city and applying Lefebvre’s spatial triad as a theoretical approach, the article describes the role of religion in the perceived, conceived, and lived space of charitable food provision in a secular Nordic welfare state. The findings show how the role of religion in the context of food assistance is subject to particular contexts and that this role is socially produced in the practices of the food banks, in the goals of the food providers, and in the lived experiences of the food recipients. The findings suggest that charitable food assistance is a social space where divergent readings of space as either religious or secular are potentially contested. The study provides a novel approach to understanding food assistance with its interconnections with religion and poses further questions for policy development, for religious organizations engaged in charitable food provision, and for future research.     

Signal modality and choice between signaled and unsignaled food

Choice between signaled and unsignaled response-independent food schedules was assessed in three experiments using a commitment procedure. In Experiment 1, subjects tested with a 5-s visual signal consistently changed from the signaled to the unsignaled schedule. Changing from the unsignaled to the signaled schedule was observed only occasionally and only at low levels. The same outcome was observed in Experiment 2 with different types of visual signals and with different stimulus combinations identifying the signal period, the signal-absent period, and the unsignaled schedule. In Experiment 3 the visual signal was replaced with an auditory signal for four of the subjects tested in Experiment 2. The subjects then changed from the unsignaled to the signaled schedule or showed a substantial reduction in choice for the unsignaled schedule. The data were assessed using a conditioned-reinforcement interpretation of choice.     

Matching-based hedonic scaling in the pigeon

Four slightly hungry pigeons chose between pairs of grains in a Findley concurrent choice procedure. For Condition I, choice involved hemp versus buckwheat; for Condition II, wheat versus buckwheat; and for Condition III, hemp versus wheat. In all conditions, frequency of reinforcement was arranged according to concurrent variable-interval variable-interval schedules. On the assumption that subjects matched their behavior and time distributions to those of reinforcer value, the choice functions obtained in Conditions I and II were transformed to yield estimates of values of hemp and wheat relative to buckwheat. These, in turn, provided predictions about behavior and time allocation in Condition III. In general, the predicted outcomes were close to those actually obtained. The results evidence the effectiveness of matching-based hedonic scales in the prediction of choice between qualitatively different reinforcers.     

Effects of body weight on discriminative-stimulus control by phencyclidine in the pigeon.

Using a color-tracking procedure with responses reinforced under a second-order schedule, the discriminative-stimulus properties of phencyclidine were studied in pigeons maintained at 70%, 80%, or 90% of their free-feeding weights. The generalization curves for phencyclidine were similar at all three body weights. Generalization curves for pentobarbital, d-amphetamine, and saline were also unrelated to body weight. These data suggest that food deprivation may not influence the discriminative-stimulus properties of drugs in the way that it influences the reinforcing-stimulus properties of drugs. The reason may be that during discrimination training interoceptive stimuli resulting from food deprivation do not become conditioned to the stimulus properties of the drug, because the food-deprivation stimuli are paired equally often with the presence and absence of drug stimuli.     

Positive conditioned suppression: an explanation in terms of multiple and concurrent schedules

Rats performed under a baseline variable-interval schedule of food presentation. A response-independent food schedule was then superimposed on the baseline schedule for different periods of time across different conditions. The response-independent schedule operated for the whole session in some conditions, intermittently for sixty second periods in some, and intermittently for ten-second periods in others. Under these latter two sets of conditions, the response-independent food schedule was stimulus correlated and alternated with the baseline schedule according to a multiple schedule. Response-independent food presentations always suppressed responding. The degree of suppression tended to increase the longer the period of response-independent food. Control conditions, in which the superimposed schedule was response-dependent, rather than response-independent, did not produce response suppression. The results fit an analysis of positive conditioned suppression phenomena in the context of multiple and concurrent schedule effects.     

Quality of Life and General Health Perception in Women with Obesity

The purpose of this study was to determine the differences in general health status and quality of life between patients who present “non-normative eating behaviours” (namely, binge eating disorder, night eating syndrome, sweet /fat food cravings and continuous nibbling) and patients without these eating behaviour characteristics. A cohort of 168 women with obesity, all candidates to bariatric surgery, aged between 15 and 65 (M = 39.04; SD = 10.86), with a body mass index ranging between 30.37 and 80.65 (M = 48.79; SD = 8.37), was studied. Participants answered to a clinical interview, to SF-36 and to ORWELL-97, after their informed consent. Results suggest that women with obesity reporting binge eating disorder, night eating syndrome and continuous nibbling show poorer general health status and worst quality of life than those who do not present these “non-normative eating behaviours”. Moreover, the general health status and the quality of life of patients with sweet/fat food cravings do not differ from those who do not report this eating behaviour. Nevertheless, patients reporting the eating behaviours studied do not differ from the others regarding their body mass index.     

USE OF COMPONENT ANALYSES TO IDENTIFY ACTIVE VARIABLES IN TREATMENT PACKAGES FOR CHILDREN WITH FEEDING DISORDERS

We evaluated the separate components in treatment packages for food refusal of 4 young children. First, treatment packages were implemented until food acceptance improved. Next, a component analysis was conducted within a multielement or reversal design to identify the active components that facilitated food acceptance. The results indicated that escape extinction was always identified as an active variable when assessed; however, other variables, including positive reinforcement and noncontingent play, were also identified as active variables for 2 of the children. The results suggest that the component analysis was useful for identifying variables that affected food acceptance.
