Modified Checklist for Autism in Toddlers

The Modified Checklist for Autism in Toddlers (M-CHAT) is a psychological questionnaire that evaluates risk for autism spectrum disorder in children ages 16–30 months. The 20-question test is filled out by the parent, and a follow-up portion is available for children who are classified as medium- to high-risk for autism spectrum disorder. Children who score in the medium to high-risk zone may not necessarily meet criteria for a diagnosis. The checklist is designed so that primary care physicians can interpret it immediately and easily. The M-CHAT has shown fairly good reliability and validity in assessing child autism symptoms in recent studies.

Question breakdown, scoring, and interpretation

The first section of the M-CHAT identifies 20 behavioral characteristics of the autism spectrum and asks if the child has experienced any of them. If the parent reports a sufficient amount of characteristics for the child in this section, a follow-up form outlining specific questions pertaining to that characteristic would be administered by the researcher. It does not have to be completed for characteristics the child does not possess. The follow-up form asks questions based on a flow-chart format, ultimately categorizing the child as “pass� or “fail� for each characteristic.

M. Chat

M. Chat (also known as Monsieur Chat and Mr Chat) is the name of a graffiti cat that originally appeared in Orléans, France in 1997. The graffiti appeared most frequently on chimneys, but was also sighted in other places, such as train platforms and at political rallies. The artist was originally anonymous, but in 2007 Thoma Vuille was caught in the act of creating the cat.

The yellow cartoon cat is characterized by its large Cheshire Cat grin. The cat is most often portrayed in a running pose, but has also been variously depicted waving signal flags, bouncing on a ball, sporting angel wings, and waving in greeting at the entrance to a train station. It is sometimes accompanied by the tag "M. Chat" in small letters.

A 2004 documentary, Chats perchés (The Case of the Grinning Cat), by film maker Chris Marker, used the phenomenon of M. Chat's appearance across France as a springboard for a reflection on the state of the country post-9/11.

During a 2010 exhibition in Paris, Vuille claimed to have 60 cats across the French capital.

WvDial

WvDial (pronounced 'weave-dial') is a utility that helps in making modem-based connections to the Internet that is included in some Linux distributions. WvDial is a Point-to-Point Protocol dialer: it dials a modem and starts pppd in order to connect to the Internet. It uses the wvstreams library.

WvDial uses heuristics to guess how to dial and log into a server, alleviating the need to write a login script.

There are some GUI tools which allows using WvDial:

Chat (mining)

Chat is a term for fragments of siliceous rock, limestone, and dolomite waste rejected in the lead-zinc milling operations that accompanied lead-zinc mining in the first half of the 20th century. Historic lead and zinc mining in the Midwestern United States was centered in two major areas: the Tri-State area covering more than 2,500 square miles (6,500 km²) in southwestern Missouri, southeastern Kansas, and northeastern Oklahoma and the Old Lead Belt covering about 110 square miles (280 km²) in southeastern Missouri. The first recorded mining occurred in the Old Lead Belt in about 1742. The production increased significantly in both the Tri-state area and the Old Lead Belt during the mid-19th century and lasted up to 1970.

Cleanup

Currently production still occurs in a third area, the Viburnum Trend, in southeastern Missouri. Mining and milling of ore produced more than 500 million tons of wastes in the Tri-State area and about 250 million tons of wastes in the Old Lead Belt. More than 75 percent of this waste has been removed, with some portion of it used over the years. Today, approximately 100 million tons of chat remain in the Tri-State area. The EPA, the states of Oklahoma, Kansas and Missouri, local communities, and private companies continue to work together in implementing and monitoring response actions that reduce or remove potential adverse impacts posed by remaining mine wastes contaminated with lead, zinc, cadmium, and other metals.
