The term “lively arts” is attributed to American writer and poet James Thurber. It was popularized in the mid-20th century as a way to describe various forms of performing arts, such as theater, dance, music, and other creative expressions.

“What art is, in reality, is this missing link,  not the links which exist.

It’s not what you see that is art; art is the gap”

— Marcel Duchamp

 

Today we refresh our understanding of the literature that guides the safety and sustainability goals of lively art events in educational settlements.  Consortia have evolved quickly in recent years, leading and lagging changes in the content creation and delivery domain.  With this evolution a professional discipline has emerged that requires training and certification in the electrotechnologies that contribute to “event safety”; among them:

ASHRAE International

Standard 62.1: This standard establishes minimum ventilation rates and indoor air quality requirements for commercial buildings, including theaters and auditoriums.

Standard 55: This standard specifies thermal comfort conditions for occupants in indoor environments, which can have an impact on air quality.

…”Your children are not your children.
They are the sons and daughters of Life’s longing for itself.
They come through you but not from you,
And though they are with you yet they belong not to you.
You may give them your love but not your thoughts,
For they have their own thoughts.
You may house their bodies but not their souls,
For their souls dwell in the house of tomorrow,
which you cannot visit, not even in your dreams…”

Citizens of the Earth depend upon United States leadership in this technology for several reasons:

Development: The GPS was originally developed by the US Department of Defense for military purposes, but it was later made available for civilian use. The US has invested heavily in the development and maintenance of the system, which has contributed to its leadership in this area.

Coverage: The GPS provides global coverage, with 24 satellites orbiting the earth and transmitting signals that can be received by GPS receivers anywhere in the world. This level of coverage is unmatched by any other global navigation system.

Accuracy: The US has worked to continually improve the accuracy of the GPS, with current accuracy levels estimated at around 10 meters for civilian users and even higher accuracy for military users.

Innovation: The US has continued to innovate and expand the capabilities of the GPS over time, with newer versions of the system including features such as higher accuracy, improved anti-jamming capabilities, and the ability to operate in more challenging environments such as indoors or in urban canyons.

Collaboration: The US has collaborated with other countries to expand the reach and capabilities of the GPS, such as through the development of compatible navigation systems like the European Union’s Galileo system and Japan’s QZSS system.

United States leadership in the GPS has been driven by a combination of investment, innovation, collaboration, and a commitment to improving the accuracy and capabilities of the system over time.

Hosting open-air celebrations such as graduations and cultural requires sensitivity to audio standards that ensure high-quality sound and audience safety.  Today at the usual hour we examine the standards covering sound system design, noise control, loudness levels, equipment specifications, weather and local environmental considerations.
Surprisingly, there are many even without approaching the not insignificant cabling system standards.  We pick three representatives titles which cross reference one another:

 

World Health Organization recommendations for limiting exposure to leisure noise (e.g., concerts) to a level exceeding 80 dBA for 24 hours or 140 dB peak sound pressure to prevent hearing loss.  Recommendations for speech heavy events will defer from musical events.

 

Audio Engineering Society Guideline AES56-2008 which provides recommendations for loudspeaker placement in sound reinforcement systems.  Key points include:

    • Height and Angle: Line array speakers are often elevated (e.g., on trusses or poles) and angled to cover the audience while reducing sound spill to non-audience areas.
    • Distance: Main speakers should be placed to avoid excessive sound pressure near the front (e.g., 95–100 dBA max for audience safety) and ensure clarity at the back.

Acoustical Society of America ASA-2010 Acoustical Performance Criteria, Design Requirements, and Guidelines for Schools.  While primarily for schools, this standard’s principles can apply to open-air educational or community events, emphasizing background noise control and speech intelligibility.  For open-air audiences at events like outdoor lectures or festivals, speaker placement should minimize interference from environmental noise (e.g., traffic, wind). The standard suggests maintaining a signal-to-noise ratio where speech is at least 15 dB above background noise for clarity.

Standards Indiana § Greenwood

“Center Grove Schools enters the 2022/2023 school year with a new high-tech safety partner — Centegix CrisisAlert — purchased in part with school safety grant money that pairs with their Emergency Operations Center that opened in January 2022.  The CrisisAlert program  puts security at the fingertips of all teachers and staff.

Both systems address what the district learned it had to work on from a school safety assessment back in 2018 – live monitoring and faster response times in an emergency.   Seven-hundred cameras will scan every school in real-time from the district’s Emergency Operations Center. — More”

Qualified Zone Academy Bonds

From the Wikipedia:

Qualified Zone Academy Bonds (QZABs) are a U.S. government debt instrument created by Section 226 of the Taxpayer Relief Act of 1997. It was later revised and regulations may be found in Section 54(E) of the U.S. Code. QZABs allow certain qualified schools to borrow at nominal interest rates (as low as zero percent) for costs incurred in connection with the establishment of special programs in partnership with the private sector…

…Funds can be used for renovation and rehabilitation projects (including energy projects), as well as equipment purchases (including computers). QZABs cannot be used for new building construction. The school district must obtain matching funds from a private-sector/non-profit partner equal to at least 10% of the cost of the proposed project. Information on the two QZAB federal mandates, 10% match and academy, can be obtained by visiting the American Association of School Administrators (AASA) school financing toolkit (see resources below).

…The normal annual allocation each year has been $400,000,000. However, during 2008, 2009, and 2010, the American Recovery & Reinvestment Act (ARRA) increased these amounts to 1.4 billion. The 2011 allocation has returned to the $400,000,000 level. The allocation is divided up by all fifty states and US possessions. QZABs are a temporary program, subject to reauthorization. The last authorization was for the calendar years 2012 and 2013. Authorizations must be used within two years following the year for which they were given, meaning that authorizations given in 2012 must be used by December 31, 2014. As of July 21, 2014, the reauthorization of the QZAB program for years 2014 and 2015 has not been passed by the U.S. Congress.  [Emphasis added*]…

From the US Department of Education:

…Schools usually fund large projects, like building renovation or construction, through debt mechanisms such as tax-exempt bonds or loans. School districts must then pay a substantial amount of interest on this debt. For schools serving low income students, QZABs reduce the burden of interest payments by giving financial institutions holding the bonds (or other debt mechanism) a tax credit in lieu of interest. The school district must still pay back the amount of money it initially borrowed, but does not have to pay any interest — typically about half the cost of renovating a school. The credit rate for QZABs sold on a given day is set by the Treasury Department…

With the COVID-19 pandemic disrupting education facility construction projects — and the prospect of at least 10 percent of the built environment rendered redundant for all time — it is enlightening to review the several sources of financing for these construction projects.

We review education industry construction project status and financing at least twice a month during our US Census Bureau Monthly Construction and Finance teleconferences.   See our CALENDAR for the next online meeting; open to everyone.  Use the login credential at the upper right of our home page.

“Rainbow Connection”

The “lightning effect” seen in carnival tricks typically relies on a scientific principle known as the Lichtenberg figure or Lichtenberg figure. This phenomenon occurs when a high-voltage electrical discharge passes through an insulating material, such as wood or acrylic, leaving behind branching patterns resembling lightning bolts.

The process involves the creation of a temporary electric field within the material, which polarizes its molecules. As the discharge propagates through the material, it causes localized breakdowns, creating branching paths along the way. These branching patterns are the characteristic Lichtenberg figures.

In the carnival trick, a high-voltage generator is used to create an electrical discharge on a piece of insulating material, such as acrylic. When a person touches the material or a conductive object placed on it, the discharge follows the path of least resistance, leaving behind the branching patterns. This effect is often used for entertainment purposes due to its visually striking appearance, resembling miniature lightning bolts frozen in the material. However, it’s crucial to handle such demonstrations with caution due to the potential hazards associated with high-voltage electricity.
