Estimating The Production Function For Human Capital: Results From A Randomized Control Trial In Colombia, Orazio P. Attanasio, Sarah Cattan, Emla Fitzsimons, Costas Meghir, Marta Rubio-Codina

Cowles Foundation Discussion Papers

We examine the channels through which a randomized early childhood intervention in Colombia led to significant gains in cognitive and socio-emotional skills among a sample of disadvantaged children aged 12 to 24 months at baseline. We estimate the determinants of parents’ material and time investments in these children and evaluate the impact of the treatment on such investments. We then estimate the production functions for cognitive and socio-emotional skills. The effects of the program can be explained by increases in parental investments, emphasizing the importance of parenting interventions at an early age.

Using The West Indian Manatee (Trichechus Manatus) As A Mechanism For Invasive Aquatic Plant Management In Florida, Aarin Conrad Allen, Edward O. Keith

Marine & Environmental Sciences Faculty Articles

West-Indian manatees (Trichechus manatus L.) are opportunistic, herbivorous aquatic mammals that occupy the warm, shallow coastal waters throughout the southeastern United States. Manatees are known to feed on large quantities of diverse plant types. Presently within the state of Florida, manatees are an endangered species facing environmental and anthropogenic threats. Several different organizations work to rescue and rehabilitate these animals for an eventual return to the wild. Also within Florida, invasive aquatic plants are becoming increasingly problematic, creating both negative economic and environmental impacts. Each year, efforts are made to control these exotic plant species through several different …

Aging is usually accompanied by a significant reduction in muscle mass and force. To determine the relative contribution of inactivity and aging per se to this decay, we compared muscle function and structure in (a) male participants belonging to a group of well-trained seniors (average of 70 years) who exercised regularly in their previous 30 years and (b) age-matched healthy sedentary seniors with (c) active young men (average of 27 years). The results collected show that relative to their sedentary cohorts, muscle from senior sportsmen have: (a) greater maximal isometric force and function, (b) better preserved fiber morphology and ultrastructure …

Consuming Poverty: The Unexpected Politics Of Food Aid In An Era Of Austerity, Maggie Dickinson

Dissertations, Theses, and Capstone Projects

This dissertation tracks the remarkable growth of food assistance in the U.S. over the past fifteen years and asks what this expansion of food aid means for poor people living in New York City. Much of the scholarly literature on welfare policy in the U.S argues that social programs have become more stingy and punitive, particularly since the passage of welfare reform in 1996. On the surface, this does not seem to be the case for the food stamp program or for emergency food providers like soup kitchens and food pantries. Since 2001 food stamp rolls have risen 120% in …

Intestinal Microbiota-Dependent Phosphatidylcholine Metabolites, Diastolic Dysfunction, And Adverse Clinical Outcomes In Chronic Systolic Heart Failure, W.H. Wilson Tang, Zeneng Wang, Kevin Shrestha, Allen G. Borowski, Yuping Wu, Richard W. Troughton, Allan L. Klein, Stanley L. Hazen

Mathematics and Statistics Faculty Publications

Background: Trimethylamine-N-oxide (TMAO) has been linked to increased cardiovascular risk. We aimed to determine the prognostic value of TMAO and its dietary precursors, choline and betaine, in heart failure (HF). Methods and Results: In 112 patients with chronic systolic HF with comprehensive echocardiographic evaluation, we measured plasma TMAO, choline, and betaine by mass spectrometry. Median (interquartile range) TMAO levels, choline, and betaine levels were 5.8 (3.6–12.1) μmol/L, 10.9 (8.4–14.0) μmol/L, and 43.8 (37.1–53.0) μmol/L, respectively, and were correlated with each other (all P < .0001 for both). TMAO levels were significantly higher in patients with diabetes mellitus (9.4 [4.9–13.2] vs 4.8 [3.4–9.8] μmol/L; P = .005) and in subjects with New York Heart Association functional class III or greater (7.0 [4.7–14.8] vs 4.7 [3.4–11.3] μmol/L; P = .02). Elevated TMAO, choline, and betaine levels were each associated with higher plasma N-terminal pro–B-type natriuretic peptide (NT-proBNP) levels and more advanced left ventricular diastolic dysfunction, but not systolic dysfunction or inflammatory and endothelial biomarkers. Higher choline (hazard ratio [HR] 1.64, 95% CI 1.22–2.20; P = .001), betaine (HR 1.51, 95% CI 1.10–2.08; P = .01), and TMAO (HR 1.48, 95% CI 1.10–1.96; P = .01) predicted increased risk for 5-year adverse clinical events (death/transplantation). Only higher TMAO levels predicted incident adverse clinical events independently from age, estimated glomerular filtration rate, mitral E/septal Ea, and NT-proBNP levels (HR 1.46, 95% CI 1.03–2.14; P = .03). Conclusion: Elevated plasma TMAO, choline, and betaine levels are each associated with more advanced left ventricular diastolic dysfunction and portend poorer long-term adverse clinical outcomes in chronic systolic HF. However, only higher plasma TMAO was associated with poor prognosis after adjustment for cardiorenal indices.

Mechanisms Underlying Weight Loss And Metabolic Improvements In Rodent Models Of Bariatric Surgery, Deanna M. Arble, Darleen A. Sandoval, Randy J. Seeley

Biological Sciences Faculty Research and Publications

Obesity is a growing health risk with few successful treatment options and fewer still that target both obesity and obesity-associated comorbidities. Despite ongoing scientific efforts, the most effective treatment option to date was not developed from basic research but by surgeons observing outcomes in the clinic. Bariatric surgery is the most successful treatment for significant weight loss, resolution of type 2 diabetes and the prevention of future weight gain. Recent work with animal models has shed considerable light on the molecular underpinnings of the potent effects of these ‘metabolic’ surgical procedures. Here we review data from animal models and how …

Novel Approach To Identify Optimal Metabotypes Of Elongase And Desaturase Activities In Prevention Of Acute Coronary Syndrome, Nathan L. Tintle, John W. Newman, Gregory C. Shearer

Faculty Work Comprehensive List

Both metabolomic and genomic approaches are valuable for risk analysis, however typical approaches evaluating differences in means do not model the changes well. Gene polymorphisms that alter function would appear as distinct populations, or metabotypes, from the predominant one, in which case risk is revealed as changed mixing proportions between control and case samples. Here we validate a model accounting for mixed populations using biomarkers of fatty acid metabolism derived from a case/control study of acute coronary syndrome subjects in which both metabolomic and genomic approaches have been used previously. We first used simulated data to show improved power and …

Development Of Real-Time Pcr Assay For Detection Of Total Bacteria In Beverage Emulsions, Essam Gamaleldin Elsisi

Theses and Dissertations

The rapid growth and expansion of the soft drinks market and the necessity to meet and maintain the consumers’ expectations of having high quality products safe for consumption, have both drawn the attention to the need for rapid and sensitive methods for the detection of potential microbial contaminations. This has made the current conventional culture-based methods inconvenient due to the relatively long periods of time they need to yield results, in addition to their relatively low sensitivity. In contrast, real-time PCR is a rapid and sensitive molecular detection technique, capable of providing quick detection and quantification methods of specific DNA …

The Impact Of A Cartoon Character’S Gender On Egyptian Girls’ Knowledge Of And Intentions Toward Pneumonia Prevention, Farah Hafez El-Shiaty

Theses and Dissertations

Pneumonia kills 11% of children under the age of five in Egypt yearly. Studies suggest that health educational cartoons are effective ways to educate children about healthy practices to prevent diseases. The literature suggests that children tend to learn better from and imitate same-gender models more than opposite-gender models. Healthy Egyptians, a non-governmental organization, developed a health educational cartoon to educate young children on the preventative practices of pneumonia through a boy called Montasser as the main character. It was hypothesized that having a female character as the main character in this cartoon would increase the girls’ knowledge of and …

The Role Of Non-Governmental Organizations In Addressing Street Children In Egypt, Reem Elmenshawy

Theses and Dissertations

Both governmental and non-governmental organizations (NGOs) have initiated programs to support street children. Despite the fact that the number of NGOs working with this group of children is not large; estimated between 25-35 NGOs, they have existed in Egypt for more than twenty five years and have developed many interventions for street children. There is very limited literature that documents this role so far. This study addresses this gap in literature through studying the role of NGOs in Egypt in developing effective interventions for street children. It discusses the current practices of the NGOs, the obstacles they face in their …

An Application Of Asset Based Community Development Approach: A Case Study From Rural Community In Egypt, Alyaa Farouk Hessin

Theses and Dissertations

Many communities in Egypt, specifically the rural areas, are unquestionably distressed places as a result of the major economic and political shifts that have occurred over the past few years. Strategies of community development are currently viewed as the radical remedy for poverty related problems. In Egypt, community development strategies are usually driven from traditional approaches including charity, needs and rights based approaches which focus on basic needs like shelters and food. These approaches have proved a deficiency as they ignore the structural causes of poverty and address symptoms only. In response to these shortages came an alternative capacity focused …
