Rediseñando la Alimentación Escolar : una inversión de alto retorno en capital humano y economías locales

Ponencia presentada en: Foro Internacional "Evidencias y tendencias para fortalecer las políticas en Nutrición y Alimentación Escolar", Lima, 29 de enero de 2019En base a la presentación del libro "Rediseñando la Alimentación Escolar : una inversión de alto retorno en capital humano y economías locales" se proponen dos paquetes esenciales para el grupo de 5 a 19 años: –Paquete de la edad escolar (5-14 años): utiliza las escuelas de nivel inicial y primaria para atender las necesidades de salud en la etapa de la niñez y la adolescencia temprana, – Paquete del adolescente (15-19 años): utiliza un enfoque mixto que incorpora a la comunidad, escuelas de nivel secundaria, medios de comunicación y sistemas de salud

School Health and Nutrition Monitoring: What Practitioners and Policy Makers Can Learn from China.

“Coverage of School Health Monitoring Systems in China: a Large National Cross-Sectional Survey” by Yan et al. provides an important demonstration of the value of monitoring national school health and nutrition programs. School-based surveys have long been used as cost-efficient monitoring tools, as they serve as a proxy for the broader health and wellbeing for the community in which they live and inform programmatic responses. Despite their importance, there is surprisingly little published on how countries operationally monitor their programs, which presents meaningful challenges for program implementers globally

The Stripe 82 Massive Galaxy Project II: Stellar Mass Completeness of Spectroscopic Galaxy Samples from the Baryon Oscillation Spectroscopic Survey

The Baryon Oscillation Spectroscopic Survey (BOSS) has collected spectra for over one million galaxies at $0.15<z<0.7$ over a volume of 15.3 Gpc$^3$ (9,376 deg$^2$) -- providing us an opportunity to study the most massive galaxy populations with vanishing sample variance. However, BOSS samples are selected via complex color cuts that are optimized for cosmology studies, not galaxy science. In this paper, we supplement BOSS samples with photometric redshifts from the Stripe 82 Massive Galaxy Catalog and measure the total galaxy stellar mass function (SMF) at $z\sim0.3$ and $z\sim0.55$. With the total SMF in hand, we characterize the stellar mass completeness of BOSS samples. The high-redshift CMASS ("constant mass") sample is significantly impacted by mass incompleteness and is 80% complete at $\log_{10}(M_*/M_{\odot}) >11.6$ only in the narrow redshift range $z=[0.51,0.61]$. The low redshift LOWZ sample is 80% complete at $\log_{10}(M_*/M_{\odot}) >11.6$ for $z=[0.15,0.43]$. To construct mass complete samples at lower masses, spectroscopic samples need to be significantly supplemented by photometric redshifts. This work will enable future studies to better utilize the BOSS samples for galaxy-formation science.Comment: 18 pages, 17 figures, 5 table

Global School Feeding Sourcebook : Lessons from 14 countries

This sourcebook documents and analyzes a range of government-led school meals programs to provide decision-makers and practitioners worldwide with the knowledge, evidence and good practice they need to strengthen their national school feeding efforts. The sourcebook includes a compilation of concise and comprehensive country case-studies. It highlights the trade-offs associated with alternative school feeding models and analyzes the overarching themes, trends and challenges which run across them

Why do some CEOs become celebrities while others don’t?

Celebrity benefits chief executives personally: increased pay, more opportunities to join boards, and protection from dismissal. But their firms do not enjoy similarly positive outcomes. These CEOs often demonstrate higher levels of complacency, risk-taking, and hubris. But what leads them to attain celebrity in the first place? Jeffrey B. Lovelace, Jonathan N. Bundy, Tim Pollock, and Donald Hambrick write that a CEO’s personal attributes, a firm’s non-conforming actions, and a CEO’s use of self-promotion tactics play important roles in attracting high levels of positive media attention — with implications for individuals, firms, and society

Deworming and Development: Asking the Right Questions, Asking the Questions Right

Two billion people are infected with intestinal worms. In many areas, the majority of schoolchildren are infected, and the World Health Organization (WHO) has called for school-based mass deworming. The key area for debate is not whether deworming medicine works—in fact, the medical literature finds that treatment is highly effective, and thus the standard of care calls for treating any patient known to harbor an infection. As the authors of the Cochrane systematic review point out, a critical issue in evaluating current soil-transmitted helminth policies is whether the benefits of deworming exceed the costs or whether it would be more prudent to use the money for other purposes. While in general we think the Cochrane approach is very valuable, we argue below that many of the underlying studies of deworming suffer from three critical methodological problems: treatment externalities in dynamic infection systems, inadequate measurement of cognitive outcomes and school attendance, and sample attrition. We then argue that the currently available evidence from studies that address these issues is consistent with the consensus view expressed by other reviews and by policymakers that deworming is a very cost-effective way to increase school participation and has a high benefit to cost ratio.Economic
