Nutritional assessment of the most frequently consumed dishes in a slum in Iquitos, Peruvian Amazon

Introduction: Large nutritional surveys in Peru have identified the magnitude and location of the different types of malnutrition. The chronic type is the most prevalent one. However, although rates may be considered as alarming (even more in rural areas), only one of these studies contains information about intake characteristics, using 24-hour recalls (R24). That is, it lacks some other systems, adapted to the gastronomical characteristics of their regions and to the bioavailability of food in each area, in order to locate the origin of this situation and, thus, propose truly effective and efficient solutions. Aim: To determine the nutritional value of the main dishes consumed by the residents of a slum in Peruvian Amazon. Methods: Ninety-eight participants completed three 24-h recalls. Based on these data, we selected the 25 most commonly eaten dishes and evaluated their nutritional composition. We took note of the homemade recipes, weights and measures. In addition, we observed preparation and cooking. The mean nutritional composition of each dish was calculated per 100 g using the Nutriplato 4.6. software. We also calculated gains or losses resulting from culinary treatments. Results: Within those which include milk, the highest energy density is the mingado de arroz. In the group of fish, the most energetic is pescado frito, while within meat-based recipes tallarín con pollo, res asada and chancho frito are the most energetic ones. Regarding prepared dishes, the juane is the highest energy density of all recipes. Inside garnish, using bananas as the main ingredient, plátano frito and madurito are the most energetic. Fats are higher in fried dishes and those which contribute most fat ratio. The same thing happens with garnish as 100 grams of plátano frito or madurito contain more than 70% of the RDA. Res asada and juane present the highest sodium level. Conclusions: If we wish to offer healthier dishes, it is necessary to change their composition and/or cooking methods, reducing the consumption of fried foods. Sodium intake should also be reduced. Two foods could be important to that aim: menudencia de pollo, rich in B vitamins and low in fat, and frijol hervido, which is rich in vegetable protein and, with rice dishes ubiquitous in this area, increases the biological value of ingested proteins.

The relationship of anthropometric measures of Hispanic children up to the age 5, to economic status and parental stature

Using data from the Hispanic Health and Nutrition Examination Survey, 1982-1984 (HHANES) of the Nutritional Center for Health Statistics (NCHS), the heights, weights and arm circumferences of 217 Mexican-American children ranging in age from six to sixty months were examined to assess whether birth weight, parental stature, and economic status greatly influenced growth patterns of Mexican-American children living with both parents.^ Heights, weights, and arm circumferences were converted to standardized values of height-for-age, weight-for-age, and arm circumference-for-age using norms developed for Anglo-American children (NCHS, 1977).^ Correlation and contingency table analysis were performed to test hypotheses concerning factors found associated with the stature of children in earlier studies.^ While relationships among childhood stature and birth weight, parental stature, and economic status were in the expected direction, few were statistically significant due to the small number of cases in the analyses. Reliable conclusions concerning these relationships require a much longer sample of families. ^

Nonlinear measures of heart rate time series: influence of posture and controlled breathing

In this study, we investigated measures of nonlinear dynamics and chaos theory in regards to heart rate variability in 27 normal control subjects in supine and standing postures, and 14 subjects in spontaneous and controlled breathing conditions. We examined minimum embedding dimension (MED), largest Lyapunov exponent (LLE) and measures of nonlinearity (NL) of heart rate time series. MED quantifies the system's complexity, LLE predictability and NL, a measure of deviation from linear processes. There was a significant decrease in complexity (P<0.00001), a decrease in predictability (P<0.00001) and an increase in nonlinearity (P=0.00001) during the change from supine to standing posture. Decrease in MED, and increases in NL score and LLE in standing posture appear to be partly due to an increase in sympathetic activity of the autonomous nervous system in standing posture. An improvement in predictability during controlled breathing appears to be due to the introduction of a periodic component. (C) 2000 published by Elsevier Science B.V.

Age and size composition, growth rate, reproductive biology, and habitats of the West Australian dhufish (Glaucosoma hebraicum) and their relevance to the management of this species

Samples of the commercially and recreationally important West Australian dhufish (Glaucosoma hebraicum) were obtained from the lower west coast of Australia by a variety of methods. Fish <300 mm TL were caught over flat, hard substrata and low-lying limestone reefs, whereas larger fish were caught over larger limestone and coral reef formations. Maximum total lengths, weights, and ages were 981 mm, 15.3 kg, and 39 years, respectively, for females and 1120 mm, 23.2 kg, and 41 years, respectively, for males. The von Bertalanffy growth curves for females and males were significantly different. The values for L∞, k, and t0 in the von Bertalanffy growth equations were 929 mm, 0.111/year, and –0.141 years, respectively, for females, and 1025 mm, 0.111/year, and –0.052 years, respectively, for males. Preliminary estimates of total mortality indicated that G. hebraicum is now subjected to a level of fishing pressure that must be of concern to fishery managers. Glaucosoma hebraicum, which spawns between November and April and predominantly between December and March, breeds at a wide range of depths and is a multiple spawner. The L50’s for females and males at first maturity, i.e. 301 and 320 mm, respectively, were attained by about the end of the third year of life and are well below the minimum legal length (MLL) of 500 mm. Because females and males did not reach the MLL until the end of their seventh and sixth years of life, respectively, they would have had, on average, the opportunity of spawning during four and three spawning seasons, respectively, before they reached the MLL. However, because G. hebraicum caught in water depths >40 m typically die upon release, a MLL is of limited use for conserving this species. Alternative approaches, such as restricting fishing activity in highly fished areas, reducing daily bag limits for recreational fishermen, introducing quotas or revising specific details of certain commercial hand-line licences (or doing both) are more likely to provide effective conservation measures.

ARAB MUSICIANS IN WASHINGTON, D.C. AREA: ETHNICITY AND IDENTITY

Musicians living in the Arab Diaspora around the Washington, D.C. metro area are a small group of multi-faceted individuals with significant contributions and intentions to propagate and disseminate their music. Various levels of identity are discussed and analyzed, including self-identity, group/ collective identity, and Arab ethnic identity. The performance and negotiation of Arab ethnic identity is apparent in selected repertoire, instrumentation, musical style, technique and expression, shared conversations about music, worldview on Arabic music and its future. For some musicians, further evidence of self-construction of one's ethnic identity entails choice of name, costume, and venue. Research completed is based on fieldwork, observations, participant-observations, interviews, and communications by phone and email. This thesis introduces concepts of Arabic music, discusses recent literature, reveals findings from case studies on individual Arab musicians and venues, and analyzes Arab identity and ethnicity in relation to particular definitions of identity found in anthropological and ethnomusicological writings. Musical lyrics, translations, transcriptions, quotes, discussions, analyses, as well as charts and diagrams of self-identity analyses are provided as evidence of the performance and negotiation of Arab identity.

An evaluation of portion size estimation aids precision, ease of use and likelihood of future use

OBJECTIVE: The present study aimed to evaluate the precision, ease of use and likelihood of future use of portion size estimation aids (PSEA).

DESIGN: A range of PSEA were used to estimate the serving sizes of a range of commonly eaten foods and rated for ease of use and likelihood of future usage.

SETTING: For each food, participants selected their preferred PSEA from a range of options including: quantities and measures; reference objects; measuring; and indicators on food packets. These PSEA were used to serve out various foods (e.g. liquid, amorphous, and composite dishes). Ease of use and likelihood of future use were noted. The foods were weighed to determine the precision of each PSEA.

SUBJECTS: Males and females aged 18-64 years (n 120).

RESULTS: The quantities and measures were the most precise PSEA (lowest range of weights for estimated portion sizes). However, participants preferred household measures (e.g. 200 ml disposable cup) - deemed easy to use (median rating of 5), likely to use again in future (all scored either 4 or 5 on a scale from 1='not very likely' to 5='very likely to use again') and precise (narrow range of weights for estimated portion sizes). The majority indicated they would most likely use the PSEA preparing a meal (94 %), particularly dinner (86 %) in the home (89 %; all P<0·001) for amorphous grain foods.

CONCLUSIONS: Household measures may be precise, easy to use and acceptable aids for estimating the appropriate portion size of amorphous grain foods.

Many valued algebraic structures as measures of comparison

This thesis studies the properties and usability of operators called t-norms, t-conorms, uninorms, as well as many valued implications and equivalences. Into these operators, weights and a generalized mean are embedded for aggregation, and they are used for comparison tasks and for this reason they are referred to as comparison measures. The thesis illustrates how these operators can be weighted with a differential evolution and aggregated with a generalized mean, and the kinds of measures of comparison that can be achieved from this procedure. New operators suitable for comparison measures are suggested. These operators are combination measures based on the use of t-norms and t-conorms, the generalized 3_-uninorm and pseudo equivalence measures based on S-type implications. The empirical part of this thesis demonstrates how these new comparison measures work in the field of classification, for example, in the classification of medical data. The second application area is from the field of sports medicine and it represents an expert system for defining an athlete's aerobic and anaerobic thresholds. The core of this thesis offers definitions for comparison measures and illustrates that there is no actual difference in the results achieved in comparison tasks, by the use of comparison measures based on distance, versus comparison measures based on many valued logical structures. The approach has been highly practical in this thesis and all usage of the measures has been validated mainly by practical testing. In general, many different types of operators suitable for comparison tasks have been presented in fuzzy logic literature and there has been little or no experimental work with these operators.

Arab Women in Translation : the Dynamics of Representation and the Construction of Alterity

Cette recherche examine la traduction et la réception en France, en Grande Bretagne et aux États-Unis de la littérature contemporaine d’expression arabe écrite par des femmes, afin de répondre à deux questions principales: comment les écrivaines provenant de pays arabes perdent-elles leur agentivité dans les processus de traduction et de réception? Et comment la traduction et la réception de leurs textes contribuent-elles à la construction d’une altérité arabe? Pour y répondre, l’auteure examine trois romans présentant des traits thématiques et formels très différents, à savoir Fawḍā al-Ḥawāss (1997) par Ahlem Mosteghanemi, Innahā Lundun Yā ‘Azīzī (2001) par Hanan al-Shaykh et Banāt al-Riyāḍ (2005) par Rajaa Alsanea. L’analyse, basée sur le modèle à trois dimensions de Norman Fairclough, vise à découvrir comment les écrivaines expriment leur agentivité à travers l’écriture, et quelles images elles projettent d’elles-mêmes et plus généralement des femmes dans leurs sociétés respectives. L’auteure se penche ensuite sur les traductions anglaise et française de chaque roman. Elle examine les déplacements qui s’opèrent principalement sur le plan de la texture et le plan pragma-sémiotique, et interroge en quoi ces déplacements ébranlent l’autorité des écrivaines. Enfin, une étude de la réception de ces traductions en France, en Grande Bretagne et aux États-Unis vient enrichir l’analyse textuelle. À cette étape, les critiques éditoriales et universitaires ainsi que les choix éditoriaux relatifs au paratexte sont scrutés de façon à mettre en lumière les processus décisionnels, les discours et les tropes sous-tendant la mise en marché et la consommation de ces traductions. L’analyse des originaux révèle tout d’abord qu’à travers leurs textes, les auteures sont des agentes actives de changement social. Elles s’insurgent, chacune à sa manière, contre les discours hégémoniques tant locaux qu’occidentaux, et (ré-)imaginent leurs sociétés et leurs nations. Ce faisant, elles se créent leur propre espace discursif dans la sphère publique. Toutefois, la thèse montre que dans la plupart des traductions, les discours dissidents sont neutralisés, l’agentivité et la subjectivité des écrivaines minées au profit d’un discours dominant orientaliste. Ce même discours semble sous-tendre la réception des romans en traduction. Dans ce discours réifiant, l’expression de la différence culturelle est inextricablement imbriquée dans l’expression de la différence sexuelle: la « femme arabe » est la victime d’une religion islamique et d’une culture arabe essentiellement misogynes et arriérées. L’étude suggère, cependant, que ce sont moins les interventions des traductrices que les décisions des éditeurs, le travail de médiation opéré par les critiques, et l’intérêt (ou le désintérêt) des universitaires qui influencent le plus la manière dont ces romans sont mis en marché et reçus dans les nouveaux contextes. L’auteure conclut par rappeler l’importance d’une éthique de la traduction qui transcende toute approche binaire et se fonde sur une lecture éthique des textes qui fait ressortir le lien entre la poétique et la politique. Enfin, elle propose une lecture basée sur la reconnaissance du caractère situé du texte traduit comme du sujet lisant/traduisant.

Animal performance and carcass characteristics of Nellore young bulls fed coated or uncoated urea slaughtered at different weights

The objective of this study was to evaluate animal performance and carcass characteristics of 64 Nellore young bulls at 22 months of age finished in a feedlot and slaughtered at five body weights (350; 455; 485; 555 and 580 kg) fed diets containing coated or uncoated urea. The experimental design adopted was completely randomized, set in a 4 × 2 factorial arrangement, and for the variables assessed in the control animals, it was 5 × 2. No effect of interaction between slaughter weights and diets were observed, so the variables were analyzed separately, compared by polynomial contrasts and by the F test, respectively. The time animals remained in the feedlot to reach slaughter weights was 66, 88, 145 and 194 days. Average daily gain (ADG) showed quadratic behavior, with a maximum of 1.44 kg/day with animals of 491.7 kg. Dry matter intake (DMI) (kg/day) was similar in all the treatments, but it decreased linearly as body weight increased. The bionutritional efficiency worsened linearly as body weight rose. The elevation in slaughter weight resulted in linear decrease in the percentage of beef round and increase in forequarter. Backfat thickness and rib eye area of the longissimus increased linearly and the percentages of muscle and protein in the carcass reduced and those of fat and ether extract increased linearly as body weight increased. Average daily gain, DMI, feed efficiency and carcass characteristics were not affected by diets containing coated or uncoated urea. However, animals fed coated urea presenter better crude fiber and neutral detergent fiber intake.

Land Management in the Central Highlands of Eritrea: A Participatory Appraisal of Conservation Measures and Soils in Afdeyu and its Vicinity

A comprehensive inventory of local and introduced soil and water conservation (SWC) measures presented in standardized fact sheets and completed with a special focus on the underlying reasons (problems) of acceptance / rejection. Different approaches are analysed and measures identified which are adapted to the specific local context. Second part of the study: soil assessment resulting in a consistent local classification of soil types and soil fertility, comparison with scientific classifications. Different topical maps show the spatial distribution of SWC measures, their condition, degradation hotspots, soil types, soil fertility and interrelations between these parameters. Based on the conclusions and the outcome of a stakeholder workshop recommendations are given for further activities in research and implementation of SWC in the Central Highlands of Eritrea.

Seasonal Variation in the Capacity for Plant Trait Measures to Predict Grassland Carbon and Water Fluxes

There is a need for accurate predictions of ecosystem carbon (C) and water fluxes in field conditions. Previous research has shown that ecosystem properties can be predicted from community abundance-weighted means (CWM) of plant functional traits and measures of trait variability within a community (FDvar). The capacity for traits to predict carbon (C) and water fluxes, and the seasonal dependency of these trait-function relationships has not been fully explored. Here we measured daytime C and water fluxes over four seasons in grasslands of a range of successional ages in southern England. In a model selection procedure, we related these fluxes to environmental covariates and plant biomass measures before adding CWM and FDvar plant trait measures that were scaled up from measures of individual plants grown in greenhouse conditions. Models describing fluxes in periods of low biological activity contained few predictors, which were usually abiotic factors. In more biologically active periods, models contained more predictors, including plant trait measures. Field-based plant biomass measures were generally better predictors of fluxes than CWM and FDvar traits. However, when these measures were used in combination traits accounted for additional variation. Where traits were significant predictors their identity often reflected seasonal vegetation dynamics. These results suggest that database derived trait measures can improve the prediction of ecosystem C and water fluxes. Controlled studies and those involving more detailed flux measurements are required to validate and explore these findings, a worthwhile effort given the potential for using simple vegetation measures to help predict landscape-scale fluxes.
