Although most closely associated with All Saints’ Day, “For All the Saints” is often sung throughout the year in Anglican churches and collegiate chapels because its theme is not confined to a single feast. It celebrates the Church as a continuing fellowship across generations, encouraging Christians in the ordinary work of discipleship. In that respect, it speaks naturally to the long green season of Ordinary Time

Music is the oldest continuously evolving grammar of ordered relationships in the Western intellectual tradition.
For all the saints, who from their labours rest,
Who thee by faith before the world confessed,
Thy Name, O Jesus, be for ever blessed.
Alleluia, Alleluia!
Thou wast their Rock, their Fortress and their Might;
Thou, Lord, their Captain in the well-fought fight;
Thou, in the darkness drear, their one true Light.
Alleluia, Alleluia!
O may thy soldiers, faithful, true and bold,
Fight as the saints who nobly fought of old,
And win, with them, the victor’s crown of gold.
Alleluia, Alleluia!
O blest communion, fellowship divine!
We feebly struggle, they in glory shine;
Yet all are one in thee, for all are thine.
Alleluia, Alleluia!
And when the strife is fierce, the warfare long,
Steals on the ear the distant triumph song,
And hearts are brave again and arms are strong.
Alleluia, Alleluia!
The golden evening brightens in the west;
Soon, soon to faithful warriors cometh rest;
Sweet is the calm of Paradise the blest.
Alleluia, Alleluia!
But lo! there breaks a yet more glorious day;
The saints triumphant rise in bright array;
The King of Glory passes on his way.
Alleluia, Alleluia!
From earth’s wide bounds, from ocean’s farthest coast,
Through gates of pearl streams in the countless host,
Singing to Father, Son and Holy Ghost:
Alleluia, Alleluia!

Today we break down the catalog for food safety in education communities; with primary attention to consultations from private standard developing organizations and federal agencies charged with food safety. We do so with sensitivity to animals and plants and sustainability of the global food supply chain. Many schools are the communal cafeterias for the communities that own and operate them and run at commercial scale.
We prepare responses to public consultations released by standards developing organizations which, in many cases, have significant conformance enterprises. Core titles are published by the ANSI accredited organizations listed below:
The ASHRAE catalog is the most cross-cutting and fastest moving catalog in the land. If you claim ownership of the United States energy domain you pretty much capture everything related campus safety and sustainability. Best to deal with it on a day-by-day basis as we usually do according to daily topics shown on our CALENDAR.

Education communities have significant food safety responsibilities. Risk gets pushed around global food service counterparties; a drama in itself and one that requires coverage in a separate blog post.*
Since 2013 we have been following the development of food safety standards; among them ANSI/NSF 2: Food Equipment one of a constellation of NSF food safety titles whose provisions cover bakery, cafeteria, kitchen, and pantry units and other food handling and processing equipment such as tables and components, counters, hoods, shelves, and sinks. The purpose of this Standard is to establish minimum food protection and sanitation requirements for the materials, design, fabrication, construction, and performance of food handling and processing equipment.
It is a relatively stable standard; developed to support conformance revenue for products. A new landing page seems to have emerged in recent months:

You may be enlightened by the concepts running through this standard as can be seen on a past, pre-pandemic agenda:
NSF 2 Food Safety 2019 Meeting Packet – Final Draft
NSF 2 Food Safety 2019 Meeting Summary – August 21-22 Ann Arbor NSF Headquarters
NSF 2 Food Equipment Fabrication Agenda – FEF – TG – 2021-01-12
Not trivial agendas with concepts that cut across several disciplines involving product manufacture, installation, operation and maintenance. We find a very strong influence of organizations such as Aramark and Sodexo. More on that in a separate post.

This committee – along with several other joint committees –meets frequently online. If you wish to participate, and receive access to documents that explain the scope and scale of NSF food safety standards, please contact Allan Rose, (734) 827-3817, arose@nsf.org. NSF International welcomes guests/observers to nearly all of its standards-setting technical committees. We expect another online meeting hosted by this committee any day now.
Keep in mind that all NSF International titles are on the standing agenda of our Nourriture (Food) colloquia; open to everyone. See our CALENDAR for the next meeting.

Towering Tribute: New Engineering Building Named for Oil Pioneer Autry C. Stephens
North façade: a curtain-wall system uses a custom frit pattern. Architecturally, the frit makes the glass read as more solid and relates its pattern and limestone-like coloration to the adjacent building. Functionally, CO says explicitly that the frit reduces solar heat gain.
East façade: instead of relying entirely on the glazing, the designers introduced angled vertical aluminum fins to respond to the harsh morning sun. The fins also echo the curved geometry of the terra-cotta elsewhere on the building. That’s a particularly nice example of an external architectural element simultaneously becoming a passive solar-control device.
South façade: interestingly, CO uses masonry itself to establish some of the visual rhythm normally supplied by curtain wall. The brick gradually racks outward and eastward, creating changing shadows through the day; its proportions and shadow lines intentionally mimic those of the north curtain wall.

George H.W. Bush 1991 University of Michigan Commencement Speech on “Political Correctness”
“Ironically, on the 200th anniversary of our Bill of Rights, we find free speech under assault throughout the United States, including on some college campuses. The notion of political correctness has ignited controversy across the land. And although the movement arises from the laudable desire to sweep away the debris of racism and sexism and hatred, it replaces old prejudice with new ones. It declares certain topics off-limits, certain expression off-limits, even certain gestures off-limits.”
