The impact of grade retention on juvenile crime
(Elsevier, 2021)
This paper studies the causal effect of grade retention in primary school on juvenile crime in Chile. Implementing a fuzzy regression discontinuity design, we find that repeating an early grade in primary school decreases ...
The Impact of Grade Retention on Juvenile Crime
(Universidad de Chile. Facultad de Economía y Negocios, 2016)
Using detailed administrative and individual data on schooling and crime records
from Chile, we estimate the effect of grade retention between 4th and 8th grade
on juvenile crime. We base our research on the rule which ...
Production strategies for short term grow-out of the Amazon River prawn Macrobrachium amazonicum (Heller 1862) in ponds
(2011-12-01)
The aim of this study was to evaluate the effect of stocking ponds using graded and ungraded juveniles and performing drained and combined harvesting on the production of M. amazonicum. A randomized completed-blocks design ...
Population structure of pond-raised Macrobrachium amazonicum with different stocking and harvesting strategies
(Elsevier B.V., 2010-09-21)
The effect of size-grading of juveniles prior to stocking, as well as selective harvesting, on the population structure of pond-raised Macrobrachium amazonicum was studied. A randomized-complete-blocks design with 4 ...

Limnology of Macrobrachium amazonicum grow-out ponds subject to high inflow of nutrient-rich water and different stocking and harvest management
(Wiley-Blackwell, 2011-08-01)
We evaluated the water characteristics and particle sedimentation in Macrobrachium amazonicum (Heller 1862) grow-out ponds supplied with a high inflow of nutrient-rich water. Prawns were subject to different stocking and ...
