The document summarizes a Campus STaR Chart assessment for East Central High School. The STaR Chart profiles a campus's progress towards technology goals in key areas, placing them at one of four levels. The assessment found the campus is working towards regular technology use by students and teachers, though keeping up with global advances is difficult. It was determined that more staff development and initiatives are needed to make technology use the rule, not exception, which would help reach students in new ways.

The document provides instructions for creating an Empire magazine cover and a Nightmare on Elm Street film poster. For the magazine cover, it describes including a bold button, masthead at the top, main image, and cover lines. For the film poster, it recommends a medium shot of the villain with half the face hidden, small credits at the bottom, a punny tagline, and the title at the bottom in red font. Both include release dates at the bottom without detracting from the main focal image.

Algunas de las preguntas se refieren a por qué el sol aclara el pelo pero oscurece la piel, por qué las mujeres no pueden pintarse las pestañas con la boca cerrada, y por qué nunca se ha visto un titular de periódico que diga "Adivino gana la lotería".

RS Industrial undertook several upgrades to its manufacturing equipment between 1982 and 2001 including modernizing its coating line with larger bulk melters and improved nipping and die cutting capabilities. During this period, Jim McElligott's product designs increased the Identification Products Division's sales from $600,000 to nearly $40 million. The division introduced many new computer printable, heat shrink, and handheld printer products for wire identification, safety products, and utility markets. It also manufactured various printers, labels, and consumables in-house or through contract manufacturing.
