In a program I am writing I want the same utility file to be run on different datasets and certain variables in the dataset. But the datasets have different sets of variables. So a nice Stata tip, adapted for my purpose, was provided by Martin Weiss via Stata listserv.
capture confirm variable name3
if !_rc {
loc vars_to_use "name1 name2 name3"
}
else {
loc vars_to_use "firstname lastname"
}
* run utility file
foreach x in `vars_to_use' {
do something to `x'
}
Le 9 mai 2018 était la journée de célébration des projets à l’école américaine appelée International School of Ouagadougou (ISO). A cette journée ou FAVL a été honoré car suite à l’invitation nous avons voir à l’école une vingtaine de projets que les élèves ont présenté tant dans le domaine de la santé, de l’environnement, de l’énergie que de l’éducation. Ces projets ont été bien présenté et nous avons été touché par le choix d’une groupe d’élèves qui ont fait le déplacement sur la bibliothèque de Korsimoro et on produits 3 livres-photos pour les enfants des 20 bibliothèques. Ils disent s’être inspiré du modèle de livre-photo de FAVL et des conseils pour réaliser ses livres. C’est avec une note de satisfaction que nous avons félicité ces élèves qui ont pu faire aboutir leur projet.
And unfortunately there is so little known by small farmers about successful bee-keeping in Burkina Faso! Low hanging fruit for development projects?
Shea (Vitellaria paradoxa) is an important fruit tree in West African parklands, and its successful pollination is a requirement for fruit production. Size-based pollinator exclusion experiments combined with visual observations showed that presence of honey bees (Apis mellifera jemenitica) was important for pollination and thereby the production of fruits and seeds. Smaller insects, mainly species of stingless bees (Hypotrigona spp. and Liotrigona cf. bottegoi) and solitary bees (Compsomelissa borneri) could partly compensate pollination in absence of honey bees, but fertilisation and fruit yield was reduced. A positive correlation between fertilisation percentage and number of honey bee colonies within radii of 900 and 1000 m was observed. The percentage of fertilisation and number of mature fruits per fascicle were higher in trees with colonies of stingless bees in the trunk when honey bees were excluded by bagging. We conclude that local beekeeping with honey bees and stingless bees is likely to have a positive influence on fruit production of shea trees in the farmed West African parklands, which speaks in favour of a pollinator friendly environment.
From a recent study in Food Science & Nutrition:
E. coli strains were found to 27.45%. Forty samples (38.24%) were unacceptable based on the aerobic mesophilic bacteria (AMB) load. Fifty‐nine samples (57.85%) were contaminated with thermo‐tolerant coliforms (TTC)…. Diarrheagenic E. coli strains were detected in 21.43% of all samples. This study showed that flamed/grilled chickens sold in Ouagadougou could pose health risks for the consumers. Need of hygienic practices or system and good manufacturing practices is necessary to improve the hygienic quality of flamed/grilled chickens. Our results highlight the need of control of good hygiene and production practices to contribute to the improvement of the safety of the products and also to avoid antibiotic resistance. Slaughter, scalding, evisceration, plucking, bleeding, washing, rinsing, preserving, grilling, and selling may be the ways of contamination.

This book was circulating in the house so I started reading. Reading and skipping. What is there to say? I mean, did someone challenge Cline? “Hey, bet you can’t write a sci fi dystopia where female characters function only as objects of desire.” And he said, “Yes I can. And for free I’ll throw in an evil all-powerful opponent whose minions cannot shoot straight.” Sound familiar?
