Limits on Anomalous Couplings from Higgs Boson Production at the Tevatron
We estimate the attainable limits on the coefficients of dimension--6
operators from the analysis of Higgs boson phenomenology, in the framework of a
gauge-invariant effective Lagrangian. Our results,
based on the data sample already collected by the collaborations at Fermilab
Tevatron, show that the coefficients of Higgs-vector boson couplings can be
determined with unprecedented accuracy. Assuming that the coefficients of all
``blind'' operators are of the same magnitude, we are also able to impose more
restrictive bounds on the anomalous vector-boson triple couplings than the
present limit from double gauge boson production at the Tevatron collider.Comment: 4 Pages, 2 figures, latex file using ReVTeX, Version to Appear in

Did Indonesia's Cries of 1997/98 Affect Child Nutrition? A Cohort Decomposition Analysis of National Nutrition Surveillance Data
This study uses a new survey of households in rural Central Java to assess the nutritional impact of Indonesia’s drought and financial crisis of 1997/98. Applying an econometric approach that distinguishes between time, age, and cohort effects to a data set with more frequent time observations over the crisis period than has previously been available, this study reveals significant nutritional impacts. While there was no meaningful decline in child weight-for-age measures, mean weight-for-height declined by over one-third of a standard deviation. Furthermore, blood hemoglobin concentration – an even more responsive indicator, and one that provides insight into the quality, as well as the quantity of the diet – also declined sharply during the crisis. While both indicators subsequently improved, neither had recovered to its pre-crisis level by January 2001. The crisis thus significantly reversed what had previously been a ten-year period of improving nutritional status in Indonesia. We also demonstrate the efficacy of applying econometric decomposition of time, age, and cohort effects to high frequency nutrition surveillance data, and present suggestive evidence of links between maternal undernutrition and the subsequent nutrition of offspring.nutrition, micronutrients, crisis, Indonesia

HPA-axis activity as a predictor of future disruptive behaviors in young adolescents
Low HPA-axis activity has been proposed as a risk factor for disruptive behaviors. However longitudinal data on this topic are practically lacking. In the present study we investigated if low HPA-axis activity predicted future disruptive behaviors. We included 1,399 boys and girls from the Dutch general population, initially aged 10-12 years. At the first assessment, basal cortisol levels were assessed. At the first assessment and at follow-up 2 years later disruptive behaviors were assessed with parent and self-report questionnaires. The results suggest that the association between low cortisol levels at 8.00 p.m. and future disruptive behaviors according to the parents was only present for boys. More importantly however, the results suggest that low HPA-axis activity is not a good predictor for disruptive behaviors, but could be valuable to identify those with a poor prognosis, once disruptive behaviors are present in preadolescence
