The Cambridge Union is the oldest debating society in the world, as well as the largest student society in Cambridge. It remains one of the highest-ranking competitive debating chambers worldwide, and hosts a range of speakers and topical debates each term.
Since 1815 the Union has been committed to the principles of free speech and of fair, open, and honest debate. Founded at a time when the university authorities attempted to restrict these freedoms, the Union remains the centre of controversial and serious debate within the University of Cambridge.
The Union has been discussing, debating, and shaping the issues that matter for the last two hundred years. Understanding how concepts work, challenging ideas, and having a frank discussion is the bedrock upon which our society is founded. It is the responsibility of the Union to ensure that these ideals are protected and nurtured for years to come.
Many people are surprised to learn what counts as a “drink”. The amount of liquid in your glass, can, or bottle does not necessarily match up to how much alcohol is actually in your drink. Even before the United States federal government withdrew from regulating alcohol, the conversation, and degree of agreement and attitude, remains remarkably regionally specific:
yet we must work to ensure that it does not divide us.”
— Guglielmo Marconi
When the electric grid and the internet are down and there is no cell service, radio can still work to help communities stabilize. Starting 2024 we will break down our coverage of the radio frequency technology standards used in educational settlements into into two categories:
Radio 300: Security and maintenance radio. These usually use a single radio channel and operate in a half-duplex mode: only one user on the channel can transmit at a time, so users in a user group must take turns talking. The radio is normally in receive mode so the user can hear all other transmissions on the channel. When the user wants to talk he presses a “push-to-talk” button, which turns off the receiver and turns on the transmitter; when he releases the button the receiver is activated again. Multiple channels are provided so separate user groups can communicate in the same area without interfering with each other.
As of this posting APCO International has no public consultations on any titles in its public safety radio standards catalog.
Radio 400: Student radio. College radio stations are typically considered to be public radio radio stations in the way that they are funded by donation and grants. The term “Public radio” generally refers to classical music, jazz, and news. A more accurate term is community radio, as most staff are volunteers, although many radio stations limit staff to current or recent students instead of anyone from the local community. There has been a fair amount of drama over student-run radio station history; a topic we steer away from.
The Low Power FM radio service was created by the Commission in January 2000. LPFM stations are authorized for noncommercial educational broadcasting only (no commercial operation) and operate with an effective radiated power (ERP) of 100 watts (0.1 kilowatts) or less, with maximum facilities of 100 watts ERP at 30 meters (100 feet) antenna height above average terrain. The approximate service range of a 100 watt LPFM station is 5.6 kilometers (3.5 miles radius). LPFM stations are not protected from interference that may be received from other classes of FM stations.
We follow — but do not respond — to consultations on titles covering the use of radio frequencies for the Internet of Things. At the moment, most of that evolution happens at the consumer product level; though it is wise to contemplate the use of the electromagnetic spectrum during widespread and extended loss of broadband services.

We do not include policy specifics regarding the migration of National Public Radio beyond cultural content into political news; though we acknowledge that the growth of publicly financed radio domiciled in education communities is a consideration in the technology of content preparation informed by the Public Broadcasting Act of 1967.
We drill into technical specifics of the following:
Radios used for campus public safety and campus maintenance
Student-run campus radio stations licensed by the Federal Communications Commission as Low Power FM (LPFM)
Facilities for regional broadcast of National Public Radio operating from education communities
Off-campus transmission facilities such as broadcast towers.
Grounding, bonding, lightning protection of transmission and receiving equipment on buildings
Broadcast studio electrotechnologies
Radio technology is regulated by the Federal Communications Commission with no ANSI-accredited standards setting organizations involved in leading practice discovery and promulgation.

The FCC is the United States’ primary authority for communications laws, regulation and technological innovation. We provide a link to the August 3rd meeting during which time rules for Digital FM Radio and Non-Federal Spectrum Usage were discussed. Campus Security Radio, National Public Radio and Student Radio are central features of education community culture and safety and are typically available when the internet is not.

To what degree does the endless and, frankly shameless, on-air fundraising by an organization with widely tolerated bias constitute de facto political fundraising for the Democratic Party? In Southeastern Michigan — in less than a 50 mile region — you can hear the same NPR “content” from six different universities: Ann Arbor, Ypsilanti, Toledo, Detroit, East Lansing, and Flint.

National Public Radio follows guidelines and best practices when conducting fundraising campaigns, but they’re not so much strict “rules” as they are principles and standards upheld by NPR and its member stations. Here are some common practices and considerations:
Transparency: NPR and its member stations are typically transparent about their funding needs and where the money goes. They often provide detailed breakdowns of their budgets and expenses.
Ethical Solicitation: Fundraising efforts should be conducted ethically and in accordance with NPR’s values. This means avoiding misleading tactics and being honest about the need for funding.
Listener Support: NPR often emphasizes the importance of listener support in funding their programming. They encourage individuals to contribute at various levels, often with incentives like member benefits.
Corporate Sponsorship: NPR also receives funding from corporate sponsors, “but they are careful to maintain editorial independence.” Sponsored content is clearly labeled, and NPR maintains strict guidelines to ensure that sponsors do not influence editorial decisions.
Member Stations: NPR member stations across the country conduct their own fundraising campaigns, often in conjunction with national NPR campaigns. These stations rely heavily on listener support and may have their own guidelines and practices.
Regulatory Compliance: NPR and its member stations must comply with relevant laws and regulations governing fundraising, including those related to nonprofit organizations and broadcasting.
Stewardship: NPR and its member stations typically prioritize stewardship of donor funds, ensuring that donations are used effectively and efficiently to support their mission and programming.
While there may not be hard and fast rules for NPR fundraising, adherence to these principles helps maintain trust with listeners and supporters.
To become a National Public Radio (NPR) member station or broadcaster, certain criteria must be met. NPR is a mission-driven organization that partners with independently owned and operated public radio stations across the United States to deliver its programming. Here are the typical criteria for becoming an NPR member station:
Nonprofit Status: NPR member stations must be nonprofit organizations, often affiliated with universities, community organizations, or governmental bodies.
Broadcast License: Stations must hold a valid broadcast license issued by the Federal Communications Commission (FCC) in the United States. This license authorizes the station to broadcast on a specific frequency within a designated geographic area.
Commitment to NPR’s Mission: Member stations are expected to share NPR’s mission of providing high-quality, non-commercial programming that serves the public interest. This includes delivering news, cultural content, and educational programming to their local communities.
Financial Stability: Stations must demonstrate financial stability and viability to ensure they can fulfill their commitments to NPR and their local communities over the long term.
Technical Requirements: Stations must meet certain technical requirements to ensure they can receive and broadcast NPR programming effectively. This includes having appropriate transmission equipment and meeting FCC regulations for broadcast quality and coverage.
Membership Dues: Member stations are required to pay annual membership dues to NPR, which help support NPR’s operations and programming.
Compliance with NPR Policies: Stations must adhere to NPR’s policies and guidelines regarding programming standards, ethics, and editorial independence.
Community Engagement: NPR values stations that are actively engaged with their local communities, including through outreach, events, and partnerships with local organizations.
Programming Commitment: Member stations are expected to broadcast a significant portion of NPR programming, including flagship shows like “Morning Edition” and “All Things Considered,” as well as other NPR-produced content.
Commitment to Diversity, Equity, and Inclusion: NPR values diversity in its member stations and encourages stations to reflect the diversity of their communities in their programming and staffing.
Overall, becoming an NPR member station involves a combination of legal, financial, technical, and cultural considerations, all aimed at supporting NPR’s mission of providing high-quality public radio programming to audiences across the United States.
A significant portion of NPR member stations are associated with universities or colleges. These stations are often operated by the educational institution’s media departments or affiliated broadcasting organizations. They serve as valuable training grounds for students studying journalism, communications, broadcasting, and related fields.
While the exact number of NPR member stations associated with universities or colleges may vary over time, it’s safe to say that a substantial portion of the network falls into this category. Many universities and colleges across the United States operate their own radio stations, and a portion of these stations choose to affiliate with NPR to access its programming and resources.
National Public Radio (NPR) member stations are permitted to transmit from facilities supported by federally funded colleges or universities, as many are licensed as noncommercial educational (NCE) stations under the Federal Communications Commission (FCC). These stations, often operated by or affiliated with public colleges and universities, meet FCC requirements for NCE licenses, which allow them to broadcast educational and cultural programming without commercial advertisements.
Key Points:NCE Licensing: NPR member stations are typically licensed as NCE stations, which can be owned or operated by nonprofit entities, including public colleges and universities. These institutions often receive federal funding, and their facilities (e.g., campus buildings or transmission equipment) can be used for broadcasting.
Funding Structure: Stations affiliated with colleges or universities may receive funding from the institution, listener contributions, corporate underwriting, and federal grants via the Corporation for Public Broadcasting (CPB). Federal funding, while a small portion (e.g., ~10% of public radio revenue), is often channeled through CPB to support station operations.
Examples: Many NPR member stations, such as WBEZ (operated by Chicago Public Media but affiliated with educational institutions) or KUT (operated by the University of Texas), transmit from university-supported facilities. Approximately half of NPR’s member stations are affiliated with colleges, sometimes operating directly from campus facilities.
FCC Regulations: The FCC allows NCE stations to broadcast from such facilities as long as they adhere to noncommercial guidelines, prohibiting promotional advertisements for for-profit entities while permitting donor acknowledgments.
Impact of Federal Funding Cuts: Recent reductions in federal funding for public media, as reported in 2025, may strain these stations, particularly those reliant on university support, as budget-strapped institutions face additional financial pressures.
There are no explicit FCC restrictions preventing NPR stations from using federally funded college or university facilities, provided they comply with NCE regulations.
The first elevator in the United States was installed at Harvard University in 1874. It was not a passenger elevator as we typically think of today, but rather a freight elevator used to move heavy items within a building. The installation of this elevator marked an important development in building technology and transportation within multi-story structures. It was based on the design of Elisha Otis, who is famous for inventing the safety elevator with a safety brake system that prevents the elevator from falling if the hoisting cable fails. Otis’ innovation played a pivotal role in making elevators safe and practical for everyday use, leading to their widespread adoption in buildings around the world.
Elevator design by the German engineer Konrad Kyeser (1405)
Education communities are stewards of 100’s of lifts, elevators and moving walks. At the University of Michigan, there are the better part of 1000 of them; with 19 of them in Michigan Stadium alone. The cost of building them — on the order of $50,000 to $150,000 per floor depending upon architectural styling — and the highly trained staff needed to operate, maintain and program interoperability software is another cost that requires attention. All building design and construction disciplines — architectural, mechanical and electrical have a hand in making this technology safe and sustainabile.
We start with international and nationally developed best practice literature and work our way to state level adaptations. Labor for this technology is heavily regulated.
Its a rarefied and crazy domain for the user-interest. Expertise is passionate about safety and idiosyncratic but needs to be given the life safety hazard. Today we review o pull together public consultation notices on relevant codes, standards and regulations today 11 AM/EDT.
At the 1853 New York World’s Fair Elisha Otis amazed a crowd when he ordered the only rope holding the platform on which he was standing cut by an axeman. The platform fell only a few inches before coming to a halt; thus proving the safety locking mechanism he had invented will work. These elevators quickly became the type in most common usage and made vertical living possible.
Most large research universities have 100 – 1000 elevators that are highly regulated, maintained by highly regulated service personnel and inspected by highly trained conformance operatives; thus our primary interest in state-specific regulations. We have a secondary interest in innovation in the technology generally. Many sustainability goals urged in academic circles — which include greater population density in smaller areas — are challenged by mobility issues.
From the project prospectus:
“…The main feature of these products is that they are an integral part of industrial, residential or public buildings. Consequently, they should be adaptable to the technical and architectural constraints of such buildings. They must also meet the capacity requirements imposed by the intended use of the building. These products are considered as means of transport and therefore represent an essential component of the functional life of the buildings in which they are installed. Contrary to most public means of transport, they are intended for free use and operation by their passengers, which makes the integration of safety an essential concern…”
We maintain the work products of this committee on the standing agendas of our Mechanical, Elevator and Global colloquia; open to everyone. See our CALENDAR for the next online meeting.
Michigan Stadium — the largest collegiate stadium in the world — has 19 elevators.
Any multi-story building requires inspection and maintenance of structural steel framework. The steel supports the building’s weight and resists environmental forces like wind and seismic activity. Over time, corrosion, fatigue cracks, or connection failures can weaken the structure, risking collapse. Inspections detect these issues early, while maintenance, like repainting or replacing damaged parts, preserves steel integrity. For student housing, occupant safety is critical, and compliance with building codes reduces liability risks. Neglecting these practices can lead to structural failure, endangering residents and causing costly repairs or legal issues. Regular upkeep ensures safe, long-lasting buildings.
During today’s session we examine the relevant standards with proposed revisions open for public comment. Use the login credentials at the upper right of our home page.
No single universal code or standard guarantees that buildings will never crack or fail structurally, as structural integrity depends on various factors like design, materials, construction quality, environmental conditions, and maintenance. However, several widely adopted codes and standards aim to minimize the risk of structural failure and ensure safety, durability, and serviceability. These provide guidelines for design, construction, and maintenance to prevent issues like cracking or catastrophic failure.
φ
Key Codes and Standards:
International Building Code (IBC): Widely used in the United States and other regions, the IBC sets minimum requirements for structural design, materials, and maintenance to ensure safety and performance. It references standards like ASCE 7 (Minimum Design Loads and Associated Criteria for Buildings and Other Structures) for load calculations (e.g., wind, seismic, snow).Maintenance provisions require regular inspections and repairs to address issues like cracking or deterioration.
ACI 318 (Building Code Requirements for Structural Concrete): Published by the American Concrete Institute this standard governs the design and construction of concrete structures.Includes requirements to control cracking (e.g., reinforcement detailing, concrete mix design) and ensure durability under environmental exposure.Maintenance guidelines recommend periodic inspections for cracks, spalling, or reinforcement corrosion.
AISC 360 (Specification for Structural Steel Buildings): Published by the American Institute of Steel Construction, this standard covers the design, fabrication, and erection of steel structures. Addresses fatigue, connection design, and corrosion protection to prevent structural failure. Maintenance involves inspecting for issues like weld imperfections or coating degradation.
Elevator, escalator and moving walk systems are among the most complicated systems in any urban environment, no less so than on the #WiseCampus in which many large research universities have 100 to 1000 elevators to safely and economically operate, service and continuously commission. These systems are regulated heavily at state and local levels of government and have oversight from volunteers that are passionate about their work.
These “movement systems” are absorbed into the Internet of Things transformation. Lately we have tried to keep pace with the expansion of requirements to include software integration professionals to coordinate the interoperability of elevators, lifts and escalators with building automation systems for fire safety, indoor air quality and disaster management. Much of work requires understanding of the local adaptations of national building codes.
Some university elevator O&M units use a combination of in-house, manufacturer and standing order contractors to accomplish their safety and sustainability objectives.
In the United States the American Society of Mechanical Engineers is the dominant standards developer of elevator and escalator system best practice titles; its breakdown of technical committees listed in the link below:
As always, we encourage facility managers, elevator shop personnel to participate directly in the ASME Codes & Standards development process. For example, it would be relatively easy for our colleagues in the Phoenix, Arizona region to attend one or more of the technical committee meetings; ideally with operating data and a solid proposal for improving the A17 suite.
All ASME standards are on the agenda of our Mechanical, Pathway and Elevator & Lift colloquia. See our CALENDAR for the next online teleconferences; open to everyone. Use the login credentials at the upper right of our home page.
