Context paragraphs:
Joiner: A joiner is an artisan who builds things by joining pieces of wood, particularly lighter and more ornamental work than that done by a carpenter, including furniture and the "fittings" of a house, ship, etc.  Joiners may work in a workshop, because the formation of various joints is made easier by the use of non-portable, powered machinery, or on job site.  A joiner usually produces items such as interior and exterior doors, windows, stairs, tables, bookshelves, cabinets, furniture, etc.  In shipbuilding a "marine joiner" may work with materials other than wood such as linoleum, fiberglass, hardware, and gaskets.

Monster.com: Monster.com is an American-based global employment website owned and operated by Monster Worldwide, Inc. It was created in 1999 through the merger of The Monster Board (TMB) and Online Career Center (OCC).  Monster is primarily used to help those seeking work to find job openings, for lower to mid-level employment, that match their skills and location.

The Hunger Site: The Hunger Site is the original click-to-donate site created in 1999 that gets sponsorship from advertisers in return for delivering users who will see their advertisements.  The Hunger site encourages visitors to click a button on the site, once per day, asserting that each unique click results in a donation "equivalent" to 1.1 cups of food.  The Hunger Site is not a charity; it is a for-profit corporation which donates the revenue from its advertising banner to selected charities.  Currently, these are Millennium Promise, Food Recovery Network, Partners in Health, Feeding America (formerly America's Second Harvest) and Mercy Corps.

Brian Trow: Brian Trow is a co-founder of Atlanta-based Foundations Investment Group, LLC, with Peter Pasternack.  He and the company, which was established in 2005, specialize in "flipping" houses.  Some of the endeavors of the company, founded in 2005, are featured in two seasons of the television series "Flip This House".  In season three, they work alongside — and provide the capital for — private house-flippers Angela and Harris Wilford; in season four, however, they go out on their own.  Trow, who is Foundations' creative director, takes on the role of general contractor on the job site and regularly provides piece-to-camera updates in the recorded flips.

Friends of WikiLeaks: Friends of WikiLeaks, sometimes reduced and stylized as FoWL, was a surveillance-resistant social network site created in support of WikiLeaks.  Founded in May 2012, the site was intended for those who support WikiLeaks and its activities to perform advocacy.  In contrast to more traditional forms of social networking, FoWL aimed at bringing together like-minded people who do not yet know each other.  To achieve this goal, the site would ask about the language the user speaks as well as any preferences in the ways of hobbies or other activities.  The site would then find six friends who share the user's views within your country, and another six from other parts of the world who speak your language.  If one of those friends cancelled their account or became inactive, a new friend would be matched to the user's circle and would replace the previous inactive one.

Steel plate construction: Steel plate construction is a rapid method of constructing heavy reinforced concrete items.  It was developed in Korea in 2004.  At a steel fabricator, assemblies are constructed.  Each assembly has two parallel plates joined with welded stringers.  The assemblies are moved to the job site and placed with a crane.  The plates are welded so that they form parallel walls joined by stringers.  Finally, the space between the plate walls is filled with concrete.

On-the-job training: On-the-job training (sometimes abbreviated OTJ or OJT), sometimes called direct instruction, is one of the earliest forms of training (observational learning is probably the earliest).  It is a one-on-one training located at the job site, where someone who knows how to do a task shows another how to perform it.  In antiquity, the work performed by most people did not rely on abstract thinking or academic education.  Parents or community members, who knew the skills necessary for survival, passed their knowledge on to the children through direct instruction.

Volumetric concrete mixer: A volumetric concrete mixer (also known as volumetric mobile mixer) is a mixer on a truck or trailer that contains concrete ingredient materials and water to be mixed at the job site to produce the exact amount of concrete needed.
