Food Access (food + access)
Selected AbstractsECONOMIC RESTRUCTURING AND URBAN FOOD ACCESS IN THE DOMINICAN REPUBLICANNALS OF ANTHROPOLOGICAL PRACTICE, Issue 1 2009Howard Rosing The article describes how economic restructuring in the Dominican Republic during the 1980s and 1990s established the basis for urban food access challenges during the 2000s. Primarily based on research in Santiago, the second largest Dominican city, the article provides insights into how export-oriented development strategies, expanding trade liberalization, domestic political struggles, and patriarchal relations influenced access to food for low-income residents. During the early 2000s, many Santiago residents were engaged in an elaborate, androcentric exchange network that linked gendered income-generating strategies to credit-bearing food merchants who were, in turn, conjoined to a sequence of brokers all of whom were eventually linked to domestic and international producers by credit relations. Analysis of these findings illustrates how and why this exchange network existed, the importance of credit relations to its maintenance, and the ways in which government and U.S. food policies influenced urban provisioning patterns among the most economically and socially vulnerable population of Santiago. I argue that the rapidly changing social and spatial configurations of Latin American and Caribbean cities calls for innovative applied anthropological research into the processes that structure access to food resources by food insecure groups. By focusing on household food procurement in conjunction with exchange relations for a key staple, the article highlights practices and policies that enable and constrain food access for such groups. The article provides empirical data relevant to scholars and practitioners concerned with understanding the structural origins of the present-day food crisis in developing countries. [source] Early handling reduces vulnerability of rats to activity-based anorexiaDEVELOPMENTAL PSYCHOBIOLOGY, Issue 7 2006O. Carrera Abstract Resistance to restricted feeding with and without wheel access was tested in rats handled (H) for 20 days since birth. Weight loss produced by 1.5-hr restricted food access was less in H than in non-handled (NH) males when tested aged 41 days. At this age combining food restriction with access to a running wheel (a procedure commonly known as activity-based anorexia, ABA) produced very rapid weight loss and no effect of handling was detected. When 75-day females were tested in the same way, under the ABA procedure H rats took longer than NH controls to reach the removal criterion. Simply restricting food access in these females produced variable weight loss, without detection of any handling effect. No differences in food intake or running were detected between H and NH rats in either males or females. In conclusion, handling seems to have a direct effect on rats' later response to either food deprivation alone or to an ABA procedure. © 2006 Wiley Periodicals, Inc. Dev Psychobiol 48: 520,527, 2006. [source] Hospital inpatients' experiences of access to food: a qualitative interview and observational studyHEALTH EXPECTATIONS, Issue 3 2008Smriti Naithani BSc MSc Abstract Background, Hospital surveys indicate that overall patients are satisfied with hospital food. However undernutrition is common and associated with a number of negative clinical outcomes. There is little information regarding food access from the patients' perspective. Purpose, To examine in-patients' experiences of access to food in hospitals. Methods, Qualitative semi-structured interviews with 48 patients from eight acute wards in two London teaching hospitals. Responses were coded and analysed thematically using NVivo. Results, Most patients were satisfied with the quality of the meals, which met their expectations. Almost half of the patients reported feeling hungry during their stay and identified a variety of difficulties in accessing food. These were categorized as: organizational barriers (e.g. unsuitable serving times, menus not enabling informed decision about what food met their needs, inflexible ordering systems); physical barriers (not in a comfortable position to eat, food out of reach, utensils or packaging presenting difficulties for eating); and environmental factors (e.g. staff interrupting during mealtimes, disruptive and noisy behaviour of other patients, repetitive sounds or unpleasant smells). Surgical and elderly patients and those with physical disabilities experienced greatest difficulty accessing food, whereas younger patients were more concerned about choice, timing and the delivery of food. Conclusions, Hospital in-patients often experienced feeling hungry and having difficulty accessing food. These problems generally remain hidden because staff fail to notice and because patients are reluctant to request assistance. [source] Daily Meal Timing is Not Necessary for Resetting the Main Circadian Clock by Calorie RestrictionJOURNAL OF NEUROENDOCRINOLOGY, Issue 2 2008J. Mendoza In rodents, entrainment and/or resetting by feeding of the central circadian clock, the suprachiasmatic nucleus (SCN), is more efficient when food cues arise from a timed calorie restriction. Because timed calorie restriction is associated with a single meal each day at the same time, its resetting properties on the SCN possibly depend on a combination of meal time-giving cues and hypocaloric conditions per se. To exclude any effect of daily meal timing in resetting by calorie restriction, the present study employed a model of ultradian feeding schedules, divided into six meals with different durations of food access (6 × 8-min versus 6 × 12-min meal schedule) every 4 h over the 24-h cycle. The effects of such an ultradian calorie restriction were evaluated on the rhythms of wheel-running activity (WRA) and body temperature (Tb) in rats. The results indicate that daily/circadian rhythms of WRA and Tb were shifted by a hypocaloric feeding distributed in six ultradian short meals (i.e. 6 × 8-min meal schedule), showing both phase advances and delays. The magnitude of phase shifts was positively correlated with body weight loss and level of day-time behavioural activity. By contrast, rats fed daily with six ultradian meals long enough (i.e. 6 × 12-min meal schedule) to prevent body weight loss, showed only small, if any, phase shifts in WRA and Tb rhythms. The results obtained reveal the potency of calorie restriction to reset the SCN clock without synchronisation to daily meal timing, highlighting functional links between metabolism, calorie restriction and the circadian timing system. [source] The relationship between socio-sexual behavior and salivary cortisol in bonobos: tests of the tension regulation hypothesisAMERICAN JOURNAL OF PRIMATOLOGY, Issue 3 2009Gottfried Hohmann Abstract Bonobos are known for their pacifistic behavior and their large repertoire of behaviors that are thought to serve conflict resolution. One is an unusual form of ventro-ventral mounting that facilitates genital contacts (GC). Various hypotheses have been proposed to explain its function. In this study we tested predictions of the tension regulation hypothesis using salivary cortisol as a marker for social stress. The results indicate a temporal relationship between GC and cortisol levels. Compared with baseline data and matched samples of unrestricted food access, rates of GC increased when access to food sources was restricted. Cortisol levels were highest when access to food was constrained. However, because the behavioral and hormonal responses occurred when viewing the stimulus at a distance and preceded the physical presence of the stimulus, we conclude that the anticipation of a competitive situation was sufficient to induce social stress. Contrary to our prediction, targets of aggression did not have higher rates of GC nor did they solicit GC more often than others. Furthermore, higher GC rates did not correlate with a more pronounced decrease in cortisol levels. Not all results obtained in this study supported the predictions concerning the regulatory function of GC on social tension and further research is needed to explore this question. However, the results indicate that the anticipation of competition may be sufficient to induce a costly physiological response, and that high levels of resource competition may have lasting effects on physical stress and stress management.

[source] Photic and non-photic entrainment on daily rhythm of locomotor activity in goatsANIMAL SCIENCE JOURNAL, Issue 1 2010Claudia GIANNETTO ABSTRACT We studied the photic (L/D cycle) and non-photic (restricted feeding) entrainment on the patterns of daily rhythm of total locomotor activity in goats. Six female Maltese goats were subjected to three different artificial L/D cycles: 12/12 L/D, 12/12 D/L and constant light. During the 12/12 L/D and 12/12 D/L, food and water were available ad libitum. During constant light, animals were subjected to a restricted feeding treatment. Total activity was recorded by means of an actigraphy-based data logger (Actiwatch-Mini®). Our results showed that goats exhibited clear daily rhythms of activity in 12/12 L/D cycle, 12/12 D/L cycle and constant light, although they showed FAA prior the feeding time during the restricted feeding treatment. Goats were diurnal, with activity consistently beginning promptly following the onset of light. Even when the L/D cycle was delayed by 12 h on some days, to the daily rhythm was re-established. During the constant light period, the onset of activity was linked to the time of food administration. Our study evidences two factors for the rhythm of total locomotor activity in goats: light stimuli (photic) and food access (non photic), strongly coupled to permit organisms the adaptive temporal coordination of behaviour with stable and unstable environmental periodicities. [source] Influence of sudden changes in management program on physiological and behavioral parameters in hensANIMAL SCIENCE JOURNAL, Issue 3 2004Ashraf M. KHALIL ABSTRACT The present study was designed to test the effects of sudden changes of food access and light duration on the physiological and behavioral parameters of hens. The physiological parameters investigated were heart rate (HR), body temperature (BT), and locomotor activity (LA) using a radiotelemetry system. After implantation of the telemetry transmitters, six hens were housed individually in cages under constant environmental conditions for 10 days with a photoperiod of 15 h light (04.00,19.00 hours), and food was available ad libitum at all times. After that, the same hens were subjected to a feed withdrawal trial, from 12.00 to 08.30 hours, followed by a lighting hour reduction trial by changing the time of lights-off from 19.00 to 14.00 hours. The physiological and behavioral data were recorded for 2 days before each trial, as control data. With the feed withdrawal trial, during the light and dark periods, HR and BT were significantly lower in the hens without food access than in the control. Whereas, LA was significantly lower only during the light period in the hens without food access than in the control. Further, the time spent resting increased significantly, but the time spent feeding decreased significantly in the hens without food access than in the control. Also, the number of times the cage was pecked and pecking of the feeder occured at a significantly higher level, while the number of times beaks were wiped occured at a significantly lower level in the hens without food access than in the control. With the lighting hour reduction trial, during the light period, HR and BT were significantly higher, whereas LA was significantly lower in the 'sudden light-off' treated hens than in the control. In addition, during the dark period, HR, BT and LA were significantly higher in the sudden light-off treated hens than in the control. Moreover, in the sudden light-off treated hens, the time spent preening and feeding decreased significantly, but the time spent resting increased significantly than in the control. It is concluded that sudden changes in a management program might result in many significant differences as were found in the physiological and behavioral parameters of hens in the present study.
