When children are free to choose what they want to play with, their development happens more easily and naturally, gradually building their stories, their perception of the world, and their critical thinking.



The fear-increasing and fear-decreasing effects of a pilot policy to reduce fear of crime

Plos.org 

by José Miguel Benavente, Daniel Goya

Fear of crime has been rising persistently in Chile, even in periods where actual crime rates have decreased, making the perception of crime an important policy issue. This paper presents the results of the impact evaluation of a pilot public policy designed to reduce fear of crime around a shopping centre in Santiago, Chile. The pilot policy consisted of installing a team including police officers and local government officials that handed out information... Читать дальше...

Evaluating the accuracy of CAD/CAM optimized stones compared to conventional type IV stones

Plos.org 

by Gülsüm Ceylan, Faruk Emir

This study compared the accuracy (trueness and precision) of stone models fabricated using two brands of CAD/CAM optimized stones Cerec Stone (BC) and Elite Master (EM), and a conventional type IV stone Elite Rock Fast (ERF). 30 conventional Type IV and scannable stone complete-arch models were scanned with a blue LED extraoral scanner, and root mean square values were obtained. 6 abutments were used in complete-arch models. The digital models were compared with... Читать дальше...

Untangling the systematic dilemma behind the roughskin spurdog Cirrhigaleus asper (Merrett, 1973) (Chondrichthyes: Squaliformes), with phylogeny of Squalidae and a key to Cirrhigaleus species

Plos.org 

by Sarah Viana, Karla D. A. Soares

Cirrhigaleus comprises a small genus of rare barbel-bearing dogfish sharks with distributions in limited regions of all oceans. Generic validity and taxonomic status of some species are upon controversies by morphological and molecular evidence that often suggest reallocation of Cirrhigaleus species into the genus Squalus. Particularly, the roughskin spurdog C. asper exhibits intermediary morphological characteristics within Squalidae that requires clarification. Читать дальше...

Come together: A unified description of the escalator capacity

Plos.org 

by Christoph Gnendiger, Mohcine Chraibi, Antoine Tordeux

We investigate a variety of aspects related to the simulation of passenger dynamics on escalators, mainly focusing on the discrepancy between the ‘theoretical’ and the ‘practical’ capacity that is observed for these facilities. The structure of the paper is twofold. In the first part, we introduce a space-continuous model to describe the transition of agents from walking on the plain to standing on the escalator. In the second part... Читать дальше...
