Livelihoods Limitations: The Political Economy of Urban Poverty in Dhaka, Bangladesh

Research in Bangladesh reveals the limitations of actor-oriented frameworks for understanding urban poverty that assess household livelihoods on thebasis of a household’s portfolio of assets or capitals. The narrow focus of these frameworks on households and their depoliticized de�nition of social capital overlook the political roots of urban poverty. The informal systems of governance that dominate resource distribution within low-income settlements ensure that the social resources necessary for long-term household improvement are con�ned to a small elite. Only through extending our analysis beyond the household level, to explore their position within this local political economy of employment and enterprise, can we recognize the limitations placed on household efforts to improve their livelihoods

The problem of accuracy in dietary surveys. Analysis of the over 65 UK National Diet and Nutrition Survey

STUDY OBJECTIVE—To investigate the prevalence and nature of low energy reporting in a dietary survey of British adults over 65 years of age.
DESIGN—Randomly selected cross sectional sample of 2060 British adults over 65 years. Four day weighed food diaries and questionnaires on health, lifestyle and socioeconomic characteristics.
SETTING—Great Britain.
PARTICIPANTS—539 women and 558 men over 65 years who were free living and completed four day food diaries.
MAIN RESULTS—A high proportion of men and women were classified as low energy reporters (LERs). Reported consumption of full fat dairy products, sugar and sweet foods, and alcoholic drinks differed most between LERs and non-LERs. Among LERs, reported protein and starch intakes were higher, fat, sugar and alcohol intakes were lower. LERs of either sex were more likely to be obese, male LERs were also more likely to belong to the manual social classes.
CONCLUSIONS—The high level of low energy reporting probably resulted from a coalescence of factors such as the weighed diary methodology and a reluctance to report consumption of unhealthy foods. The use of validatory biomarkers such as doubly labelled water needs to be more widespread.

Under-Reporting of energy intake in elderly Australian women is associated with a higher body mass index

Design: Dietary intake was assessed using a 3-day weighed food record. Protein intake was validated by 24-hour urinary nitrogen. To examine under-reporting, participants were grouped according to their energy intake and compared to the Goldberg cut-off equation. Logistic regression was performed to assess the influence of body mass index (BMI) and social-demographic factors on under-reporting. Setting: Community dwelling elderly women from Perth, Western Australia. Participants: 217 elderly women aged 70–80 years. Results: Under-reporters had a higher physical activity level (p<0.001) compared with acceptable-reporters. The under-reporters also had a higher body weight (p=0.006), body mass index (BMI) (p=0.001), waist (p=0.011), hip circumference (p<0.001), whole body fat mass (p<0.001) and percentage body fat (p<0.001) than acceptable-reporters. Under-reporters had a significantly lower intakes of protein, fat, carbohydrate and alcohol (p<0.001) and fewer reported food items, compared with acceptable reporters. However, 24-hour urinary nitrogen was only marginally different between the two groups (p=0.053). Participants with a higher BMI were more likely to under-report their energy intake (BMI=25–29.9: odds ratio=2.98[95% CI=1.46–6.09]; BMI≥30: 5.84[2.41–14.14]). Conclusion: Under-reporting energy intake in elderly women was associated with a higher BMI, body fat and higher self-reported physical activity levels. A higher BMI (≥25) appears to be most significant factor in determining if elderly women will underreport their food intake and may be related to body image. These results have implications for undertaking surveys of food intake in elderly women

ATTITUDE MEASURES IN EVALUATION RESEARCH: A RESEARCH NOTE

The paper focuses on the use of attitude measures in evaluation research. It is suggested that attitude measures can assist evaluators in surmounting the problems of assessing program effectiveness both in process and impact evaluations. Attitude change can be conceptualized as the intended output of programs, as intervening between program variables and behavior or as proxy measures of behavioral target variables that are not readily measurable. Attitude measures can play avital role in evaluation research if an adequate methodology is employed. Copyright 1986 by The Policy Studies Organization.

Transpression and tectonic exhumation in the Heimefrontfjella, western orogenic front of the East African/Antarctic Orogen, revealed by quartz textures of high strain domains

The metamorphic basement of the Heimefrontfjella in western Dronning Maud Land (Antarctica) forms the western margin of the major ca. 500 million year old East African/East Antarctic Orogen that resulted from the collision of East Antarctica and greater India with the African cratons. The boundary between the tectonothermally overprinted part of the orogen and its north-western foreland is marked by the subvertical Heimefront Shear Zone. North-west of the Heimefront Shear Zone, numerous low-angle dipping ductile thrust zones cut through the Mesoproterozoic basement. Petrographic studies, optical quartz c-axis analyses and x-ray texture goniometry of quartz-rich mylonites were used to reveal the conditions that prevailed during the deformation. Mineral assemblages in thrust mylonites show that they were formed under greenschist-facies conditions. Quartz microstructures are characteristic of the subgrain rotation regime and oblique quartz lattice preferred orientations are typical of simple shear-dominated deformation. In contrast, in the Heimefront Shear Zone, quartz textures indicate mainly flattening strain with a minor dextral rotational component. These quartz microstructures and lattice preferred orientations show signs of post-tectonic annealing following the tectonic exhumation. The spatial relation between the sub-vertical Heimefront Shear Zone and the low-angle thrusts can be explained as being the result of strain partitioning during transpressive deformation. The pure-shear component with a weak dextral strike-slip was accommodated by the Heimefront Shear Zone, whereas the north–north-west directed thrusts accommodate the simple shear component with a tectonic transport towards the foreland of the orogen
