The Value People Act

Proposal: Alteration to Federal (and State) IRS tax code to allow valuation of individual headcount as intangible assets.

Purpose: Establish a basic value (e.g. $10,000 USD) per full-time or part-time employee to be recorded as an intangible asset on an organization’s balance sheet.

Conditions: Does not differentiate employee headcount by any Title IX categories or payroll expense in calculating base employee value (i.e. a CEO is equal to a mailroom clerk for the purposes of base valuation)
Benefit and Risk Analysis:

Does not affect Income Statement (tax revenue) or alter normal payroll-related expenses.

Adds a “book value” for retaining and re-deploying employees for growth and/or surge capacity purposes.

The $10,000 USD valuation represents a basic worth of an individual based upon 50 percent of a federal minimum wage, less indirect and overhead expenses. It represents only a general approximation and is designed to level-out over the payroll headcount population.

Easily auditable as asset valuations (per balance sheet) are routinely audited by financial lenders, IRS, SEC, – reconcilable against required payroll records. (1 SSN/TIN = 1 headcount)

We treat office furniture, computers, and capitalized assets as valuable because they are a measurement of an organization’s overall stability.

Employers who retain headcount, even if relatively idle or unapplied, are recognized financially for higher stability or capacity.

Employee headcount size should be an equal measure of a firm’s size, capacity and potential stability similar to how retaining capital assets and other forms of personal property increase an organization’s “book” value.

Encourages headcount retention, and discourages mass layoffs in favor of seeing longer term strategic investment in assets.

Discourages mass outsourcing of production labor to non-payroll entities by encouraging workforce stability.

Can build-in effective workplace presence conditions to encourage on-site workplace improvement (a person is counted as an asset, if primary work is at an organization’s established work location; work from home, remote work or field workers are not counted as an intangible asset for this recategorization – only work positions given a permanent work locations can be counted.)

Organizations seeking to abuse this policy are effectively self-policed. Inflated headcounts for over-valuation purposes are auditable, and ineffective at influencing Income Statement results (these are non-depreciated intangible assets.)

See-saw hiring and firing is discouraged as temporarily inflating asset valuation is similar to the effect of short-term seasonal location leasing (inflates short-term expenses and is adjusted during balance sheet analysis for purposes of capital valuation).

Existing Generally Accepted Accounting Practices need little to no modification to adopt this revision. The execution is the addition of an Intangible Asset category based upon payroll headcount multiplied by a fixed value (per above suggested $10,000 USD value)

An organization that attempts to abuse this intangible asset category, e.g. hiring 90 percent executive level employees and 10 percent production staff, sees the same value as a 10 percent executive staff with 90 percent production employees, but the effective impact is the high-expense to income ratio of the former versus the latter. (Asset Turnover ratios account for this attempt to circumvent the intent of this revision.)


Google forms and regular expressions for response validation

I was kind of shocked with the proliferation of teachers now using Google Classroom to conduct classes, that the documentation for the Quiz sections of the Classwork assignments is quite insufficient (or presumes you’re an IT geek like me, and can just figure out what programming is available to you.)

The example situation is given by this Blog entry related to Google Classroom and students’ answers being marked Incorrect because on Short Text responses, every answer is matched as a “literal” string – that is, upper and lowercase letters MATTER (a lot!)

Link to:
Student’s answers were marked wrongly in a short answer quiz by Google Forms.

The odd thing is while Google provided a solution for simple e-mail address validation, and various numerical responses, it’s been horrible at dealing with text answers.

The answer is in the 3rd category of Response Validation: Regular Expressions. RegEx’s are commonly used in programming languages and OS shells (like Linux, Unix, HPUX, etc.) since when scripting various commands, we often need to parse parameters and do things with various input like file directory listings, and long lists of things separated by some arbitrary character (like a comma or a vertical bar character.)

Thus here in my example, dealing with a student who was marked with Incorrect answers simply because they didn’t provide the exact case required by the 3 answer versions entered by the instructor (e.g. “Any Dog”, “any dog”, “ANY DOG”) – and the student typed “Any dog” and got it marked Incorrect.

One more typical way to prevent this is specifying in the Quiz preamble the exact format responses you want as an instructor for the short answers. For example, “Please enter all short answers in lowercase letters only, with no leading or trailing space or tab characters.”

But a more practical way is exercising that Regular Expression engine that’s built into Google Forms.

My example question wanting a response from the student like “inner core” (preferably providing a graphic picture of the planet’s layers and just labeling them A/B/C/D/E would have been simpler, but maybe I’m testing vocabulary at this point.)

Selecting the Response Validation type “Regular expression” and using “Matches” the pattern: “^[A-Z]” is interepreted as meaning, “if the Short answer text contains any uppercase letters from A to Z” then display the warning text “Please use all lowercase answers only!” – and do not accept the answer, as submitted.

Regular Expressions can get really complicated, but if you think of them as basically describing what’s in a string of text and matching it as either TRUE or FALSE (and preferably keeping your Answer expectations limited unless you happen to be teaching a course in OS-level scripting, in which case, go ahead and get as complicated as you’d like…) I think you’ll find your student’s will be gently guided into providing the answers in the form you were thinking of when you prepared the Quiz.

And isn’t that what this was all about in the first place?

Here’s a link to a more thorough (and lengthy, and complicated) discussion of the power of Google Forms using Regular Expressions:

Westbound on the 15
Leaving Vegas behind
Plexiglas on the tables
Buffets politely declined
Up ahead in the distance
An agricultural stop
But instead of looking for fruits
Thermographic cameras pop

Checking out at TJ’s
Got my cauliflower rice
Karen comes in screaming
No masks, freedom and vice
Seems like peace and quiet
Are so far away
Yet only six months have passed
Since I heard them say

Welcome to our COVID California
Such a lovely place,
A chaotic space
Masking it up in our COVID California
Any time of year,
You’re not welcome here

Facebook’s full of bullies
Twitter’s gone insane
Newsom’s got himself a recall
Garcetti’s in his own lane
Health officials calling it quits
They can’t stand the heat
Hoping for some better stats
But Rona’s got us beat

Keeping socially distanced
Working from home all the time
Try to vacation out of the State
Find a 2 week mountain to climb
The health commissioners
All showed us the way
We ignored all the warning signs
Just to hear them say

Welcome to post COVID California
Such a lovely place,
An infected trace
Masking it up in post COVID California
Any time of year,
we’re infectious here

Silicon Valley’s tripping
Last year was so nice
“We are all just prisoners here
Of our own device”
Bears, coyotes and cougars
Have replaced the police
Nature’s just taking back it’s land
And we’re just here on lease

Is there a new vaccine
Can there be a cure
Acoording to the internet
You can never be sure
Here in the Golden State
You get what you receive
You can check out any time you like
But you can never leave”

Replace a Yamaha PSR-S900 Keyboard LCD Display

Full  Keyboard
Yamaha PSR-S900 Arranger Keyboard Full-view

I have one of these (Yamaha PSR-S900 Arranger Keyboard Workstation) and after 7 years, the display started going defective – half of the screen was duplicated, lines running through the middle of the display.

This renders use of the keyboard relatively impossible (because there is still a composite video out that can be sent to a portable DVD/LCD player, which will still work for the purposes of reading what’s on the display – your patch selections, mixer settings, scoring, sheet music, file selections, etc.)

I hit eBay and found a few replacement display units for about $150 (shipped from China, but made in Japan), and figured it would be worth trying (after all, a new PSR-S950 still runs about $2000.)

The replacement looks like this:

There’s a single pair red/white power lead with a small white modular plug used to connect it to the high-voltage power daughterboard. (my plug had one fewer white connections, so I used a modeling knife to trim off the extra middle connector).

The display itself connects via a 10-wire flat ribbon connector that is press-fit into the LCD’s connector. These are the somewhat fragile, but when carefully removed, basically easily re-inserted into the same receptacle (similar to re-wiring a video game console mod.) In the photo, this receptacle is on the right-center side of the display.

Since I didn’t happen to have the service manual, we dive in with the screwdriver (all phillips-head).  Flipping the keyboard over and laying it on a mattress (to avoid scratches,) you’ll find 14 3/4 inch panel screws,  4 slightly longer 1-1/2 inch panel screws used in the center holes of the keyboard, and about 24 larger headed 1-inch panel screws connecting 2 wood panels to the speakers and bottom frame.  You get to remove ALL of these to get the bottom and top shells separated (just keep them in separate dishes/jars.)

The bottom assembly sort of resembles this view from a PSR-1500 (for general reference – the PSR-S900 is more symmetrical in design) The larger screws are connecting the bottom boards to the 2 speaker enclosures and then attaching the wood panels to the bottom plastic shell; the smaller screws go into those taller pyramid-looking tower holes in the bottom case:

This is an interior view of where the LCD is actually mounted (underneath the front panel; this view is of the bottom of the top half of the keyboard):

To access this view, you will be removing the 6 mounting screws holding the CPU board box (the large aluminum vented box sitting on top of the LCD panel area.)  There are grounding wires on 3 sides of this box that are simply attached with more of the small panel screws.  You can either remove the screws that attach the box to the mounting posts, or the screws that hold the posts to the top assembly (whichever ones you can access most easily.)  The only connections I removed to access the LCD were the ethernet cable plugging into the CPU box, and the 2 white multi-wire connections that plug into the back-panel connector board (the one that has the USB plugs, video connectors and MIDI In/Out – it’s mounted to the top (silver) case assembly):

Once the CPU box is unmounted and moved aside (untaping the wires that are taped to the box), you can usually access the first 2 (of 4) screws mounting the LCD to the front panel (these are the 2 closest to the keyboard.) You can remove just the screws attaching the LCD to the aluminum mounts (you do not need to remove the mounts themselves).  To access the other 2 (the ones towards the back panel), if you don’t have a right-angle screwdriver that can fit under the back-panel connector board (about 1-inch clearance), you can remove the 6 screws holding the connector board to the top case assembly (4 of these have bendable wire tie-downs on them; the other 2 seem to hold the mylar foil shielding tabs.)  There is also a single screw that connects the coaxial video connector to the back panel that must also be removed to move the board.

Inside my particular model (which might have been an earlier build than the one my replacement LCD was designed to fit) the high voltage board was connected with a longer set of leads to the defective LCD.  So I unmounted it, rotated it clockwise 90 degrees to move the connector closer to the LCD, and re-mounted it using a single screw to hold it in-place again.

After un-mounting the defective LCD, I removed the existing ribbon connector and before mounting the new one, re-attached the ribbon into the new LCD (drawing a line with a marker on the ribbon helps you remember how deep it was plugged in before).  Plugged in the HV power lead and tested the power up to confirm the new display actually works (the first time, there were a bunch of alternating shadows, indicating I hadn’t seated the ribbon connector properly.)

4 screws back in to hold the LCD, 6+1 screws to re-mount the connector board, 6 more to remount the CPU box (and re-connect the ground wires, and 2 of them hold the box shut), then you can shut the case and replace all of those other screws you took out that hold the case together.

Nothing particularly technical – mostly a bunch of screws and tape.  And about an hour and an eBay purchase later, the keyboard is back up and running fine.
