More in depth Student starts about how he thinks the supervisor functions and what can be improved like for example: We use longitudinal data on BMI for a national sample of fifth graders from the Early Childhood Longitudinal Study — Kindergarten Class ECLS-K and an instrumental research paper on alzheimers IV approach that leverages the well-documented fact that junk foods are significantly more prevalent in middle and high schools relative to elementary schools Finkelstein, Hill and Whitaker But this effect is primarily driven by adolescents with an overweight parent, which the authors interpret as a measure of family susceptibility. Our estimates suggest that the caloric contributions of in-school junk food purchases are likely to be small.
The literature does provide some evidence of substitution of caloric intake across meals and locations among adults Anderson and Matsabut the evidence is less clear regarding children for whom parental oversight can also play a role.
In recent years, several states, districts, and schools have enacted competitive food policies that are more restrictive than federal regulations.
In the absence of a single data source containing information on school food policies and BMI among adolescents, the authors use a two-sample IV approach that employs county, state, and regional characteristics as instruments to capture budgetary pressures on schools. After discussion and approval by your supervisor the work assignment is distributed among all FPE group members.
First-stage regressions confirm that combined school attendance is a strong predictor of junk food availability. Even if the IV point estimates were statistically significant, they would still represent only minor increases in BMI and obesity, generally one-third of one percent.
Our main finding is that junk food availability does not significantly increase BMI or obesity among this fifth grade cohort despite the increased likelihood of in-school junk food purchases. FPE is having their group meeting on Thursday mornings, starting at 8.

Within 3 weeks you'll write a work assignment about the background and the goals of your research. Guidelines for the evaluation meeting After 6 week student and supervisor have an evaluation talk.
We all enjoy reading Panchtantra together.
K-8, K or middle school e. The debate draws from largely cross-sectional research that rarely addresses the potential endogeneity of the school food environment. But this effect is primarily driven by adolescents with an overweight parent, which the authors interpret as a measure of family susceptibility.
Also how the thesis goes according to expectations of both parties.
Evaluation meeting After 1. Plausibly exogenous cover letter showroom manager in junk food availability across a cohort of fifth graders is identified using diet pepsi case study grade structure in their schools.
Measurements are superior to self- or parent-reported height and weight data that may introduce non-random measurement error. On the other hand, supporters argue that revenues from these food sales provide much-needed funding for schools, especially in times of budgetary pressures Gordon et al a. They find that a 10 percentage point increase in the proportion of schools in the county that offer junk foods leads to a 1 percent increase in BMI.

And, finally, we find little support for the notion that children substitute calories from healthy foods or increase their physical activity to compensate for increased junk food intake. Abstract Despite limited empirical evidence, there is growing concern that junk food availability in schools has contributed to the childhood obesity epidemic.
Oral presentations After weeks, you'll give a short presentation 10 min. Your presentations are always reviewed with focus on the contents and the presentation techniques.
Junk Food in Schools and Childhood Obesity
Then the supervisor does the same. Last to be discussed are the issues that come forward and together we can look at solutions. In Section 4, we describe our empirical strategy, which leverages longitudinal information on BMI and implements an instrumental variables approach to identify the causal impact of junk food availability.
The remainder of this paper is organized as follows.
Finally, Section 6 concludes with the policy implications of our findings. Starting the thesis project On the first day of your thesis project, your supervisor will introduce you to the group and Marjan de Lange will deal with some administrative issues.

Setup case study 2.1 meridian water pumps the talk First the student explains what he or she wants to discuss. These results are robust to alternative measures of junk food availability and sample restrictions.
At the beginning of the project you and your supervisor will draw up a contract to determine the contents of your thesis, the time schedule, the supervisors, etc. Moreover, the absence of any effects on overall food consumption and physical activity further support the null research paper on alzheimers for BMI and obesity.
The U. We first discuss junk food availability in schools and the findings from the existing literature in Section 2. Goal is to discuss each others functioning. During your project you will have regular meetings with your supervisor to discuss results. We find that junk food availability has small positive associations with BMI and obesity in basic OLS models that only control for a limited set of covariates, but those associations become insignificant when controls for BMI at school entry and state fixed effects are added.
In this paper, we estimate the effects of junk food availability on BMI, obesity, and related outcomes among a national sample of fifth-graders.
We expect all group members as a thesis student you are seen as one of our group members to attend the plenary group meetings. Further tests for instrument validity including an examination of sorting and peer effects support our use of the instrument.
The frequency of these meetings will be determined together with your supervisor. The purpose of this meeting is to improve food thesis pdf, not to judge!
Guidelines for the evaluation meeting
Introduction The prevalence of childhood obesity in the US is at an all-time high with nearly one-third of all children and adolescents now considered overweight or obese Ogden et al Our estimates suggest that the caloric contributions of in-school junk food purchases are likely to be small.
At the local level, two of the largest school districts in the nation, New York City Public School District and Los Angeles Unified School District, imposed a ban on soda vending in schools in andrespectively. More in depth Student starts about how he thinks the supervisor functions and what can be improved like for example: The models also produce the expected findings on various falsification tests.
It is our habit that new group members present themselves by mentioning your name, your research subject and the name of your supervisor.
First, to our knowledge, ours is the only study that addresses the endogeneity of the school food environment among younger children. Sales of competitive foods have the potential to generate significant revenues for schools.
Normally you start your project by reading literature to have more background knowledge about your subject. Our paper adds to the existing literature in its sample, methodology and scope. Considerable attention has been focused on schools in an attempt to identify policy levers that will help reverse the obesity epidemic.
Competitive foods are available in a large share of schools, although the availability of these foods varies significantly across elementary, middle, and high schools. We argue that a fifth grader attending a combined e.

- These measurements are used to compute BMI, defined as weight in kilograms divided by height in meters squared.

Our IV models, which address potential bias in the OLS models, generate somewhat larger, albeit less precise, point estimates that are also not statistically significant. Together with your supervisor you will decide when to start with the actual research. The schedule of the Thursday morning session is sent via email.
We also present supporting evidence from models of in-school purchases of junk food, total consumption of various healthy and unhealthy items, and physical activity. Specifically, the total amount of soda and fast food consumed in- and out-of-school, is not significantly higher among those children with greater exposure to junk food in school i.
Moreover it will be compulsory to follow a safety course, since you have to be aware of the risks of your activities in the lab and know the rules for safety.
The focus on fifth graders is useful because junk food regulations are increasingly targeting elementary and middle schools. It is useful to include a picture in the form.
