Could Las Vegas Have Been Prevented? Easy – by Douglas W. Green, EdD

Could Las Vegas Have Been Prevented? Easy – by
Douglas W. Green, EdD explains how to avoid the kind of massacre that took place in Las Vegas.

Vegas

Same Old Arguments

  • About all I have heard since the Las Vegas massacre is arguments from the left and right about gun control. This is all pretty reflexive and you hear the same stuff after every mass shooting. I’m not saying that the gun control debate shouldn’t go on, but it would be nice if we could also hear a more creative analysis that takes the specifics into consideration.

Hundreds of Sniper Locations

  • This massacre would be easy to prevent without any change in our gun laws. What made this possible was the fact that the concert venue had hundreds of sniper locations above the scene. Last week I saw Paul McCartney at the Barclays Center in Brooklyn. There is no way anyone could get a gun in there let alone all the guns the shooter got into his hotel room.
  • The lesson is, don’t set up a concert venue with so many potential sniper points above the concert that can be accessed by someone who doesn’t have to go through concert security. This isn’t difficult, but it’s up to the people who set up these concerts. I suspect the cost of setting up this outdoor concert venue with access to snipers was a lot less than the folks in Brooklyn paid for the billion-dollar Barclays Center. 

Some Outdoor Venues are Safe

  • Last month I attended a Bon Jovi concert down the street at Enjoy Golf Course in Endicott, NY. Like Las Vegas, it was an outdoor venue, but if you wanted to get in and take a seat in one of the high altitude skyboxes that could serve a sniper positions, you needed to get a gun in the door through the metal detectors and you wouldn’t be alone in your skybox.
  • It should be easy to prevent this kind of mayhem if you avoid setting up concert venues that can be targeted by people in neighboring buildings without the ability to prevent people from getting guns to a room with a view of the concert.

How About the Hotel?

  • There are two issues here. The first relates to the two windows that the shooter broke with a hammer prior to the shooting. These are windows like many hotels have that are not designed to be opened by tenants. If they aren’t designed to be opened, there should be some way to know when they are hammered open. This would involve some expense, but if the hotel equipped the windows with sensors, the people at the front desk would know which windows have been breached immediately.
  • The other thing a hotel could do, if not today but probably in the future, is to use their cameras and a bit of artificial intelligence to spot someone coming in multiple times with loads of stuff. The guns and ammo that were brought into the room took several trips. He must have used some large containers that would have been easy to spot via video and/or alert people watching the lobby or the front door.

Housekeeping’s Role

  • Finally, what about the people who were visiting the room on a daily basis? I think hotels should tell their staff to take a look in closets and drawers quickly as they are making the beds. If guests say they don’t want such service, a security staff member should be sent to take a quick look at the room each day. Steven Wynn says that anytime a do not disturb sign is up for 12 hours it is investigated. His housekeeping staff also looks around. See the New York Post for more on this.
  • I send my prayers and sympathy to all of the people impacted by the terrible event. I also think that this particular type of massacre is easy to prevent. If you can, please do so. Also, don’t attend any outdoor events with line of sight to places people can access without going through concert security.

Data Visualization Resources for Lawrence C. Stedman’s Class at Binghamton University

Tuesday, July 11th, 2017

Today I’m doing a guest presentation at Binghamton University for Lawrence C. Stedman’s Education 680: Principles of Visualization and Data Analysis. In the process of preparing, I created this post, which you will also find linked at the left of my home page.

One Way to Use a Correlation

MLB Correlation
With an r squared of about 0.2, it means that money counts for 20% of the wins. This can make a difference, but not with every team. The teams above the line get more for their money.

Why You Can’t Trust Some Statistics

The Trouble with Averages: The Impact of Major Life Events and Acute Stress May Not Be What You Think – Anthony Mancini, Ph.D.

Coontz, Stephanie, When Numbers Mislead, The New York Times, May 25, 2013.

Orin, Ben. Why Not to Trust Statistics, mathwithbaddrawings.com, July 13, 2016. These simple drawings show you in an easy convincing manner how any statistic can be misleading.

Weinberg, Neil. Stats to Avoid: Batting Average, FanGraphs.Com, February 20, 2015. This is a good example of a poplular use of average that has been recently discredited.

Books That Debunk Current Federally Mandated Testing and Therefore Any Data Visualization Done With Them – Links to my summaries are included.

Zhao, Youg (2016). Counting What Counts: Reframing Education Outcomes – Yong Zhao and friends take on the current system with its focus on standardized tests and their sole focus on cognitive skills. Chapters are devoted to defining a variety of non-cognitive skills that are connected with success in life and the current status of how to assess them. They make a case for a new paradigm that would move the system towards more personalized learning and assessment.

Harris, Phillip, Smith, Bruce M., and Harris Joan (2011). The Myths of Standardized Tests: Why They Don’t Tell You What You Think They Do – This provides great ammunition for anyone who wants to join the fight against the test and punish reforms that schools and students are currently suffering from.

Amrein-Beardsley, Audrey (2014). Rethinking Value-Added Models in Education: Critical Perspective on Tests and Assessment-Based Accountability – This describes and analyzes the imposition of value added test-based evaluation of teachers, the theory behind it, the real-life consequences, and its fundamental flaws.

Kamenetz, Anya (2015). The Test: Why Our Schools Are Obsessed with Standardized Testing – But You Don’t Have to Be – Anya Kamenetz explains in some detail the ten things wrong with state tests along with some history and politics. She goes on to tell educators and parents what they should do to help kids survive the madness. Anyone who dislikes state test should get this book.

Kuhn, John (2013). Test-and-Punish: How the Texas Education Model Gave America Accountability Without Equity – John Kuhn follows the history of the modern education reform movement from its roots in Texas. While the tone is strongly one-sided, John makes a compelling case for reforms that diagnose-and-support and finds a way to finance schools in a more equitable manner. If you haven’t joined his battle, it may be time.

I suspect that this is the case due to the fact that it was produced by the same people who sell the tests and the value-added model to the state.

Wack a Mole

As a principal, I was fond of saying “if you don’t have ADHD when you take the job, you will have it two weeks later”. I supervised 70 adults and dealt with 530 students and their parents, as well as my follow administrators and the Superintendent.

It only took a small subset of this hoard to want my attention at the same time for the job to seem like playing the ‘Whack-a-Mole’ carnival game.

Anyone who aspires to this job needs to realize this and be prepared to deal with it. As a principal for 13 years, I believe I managed the hectic pace with success, so for anyone who wants this job or who already has it, here are my top tips on how to stay on track.

Sweden’s Cashless Economy: Pros & Cons – Great Student Debate Topic

Thursday, July 7th, 2016

The Björn Ultimatum: Two Men Fight Over Sweden’s Move to a Cashless Economy by Mallory Pickett covers both sides of the battle to get rid of cash altogether. This would be a good article for students to read and debate. As a Swedish-American who visits Swedish relatives regularly, I’ve seen a number of innovations like this that start there before being adopted in the US. @wired, May 2016 pp. 102-111.
Kronor

You Rob Banks Because That’s Where the Money Is.

  • On April 13, 2013, a man walked into the Stockholm branch of Skandinaviska Enskilda Bankan and announced that “this is a robbery, I want cash.” The staff calmly explained that there was no cash on the premises. The robber was then pointed at a sign that read “This is a Cash-Free Location.” What the robber had not realized was that Sweden was at the forefront of a global economic shift to where cash is increasingly unnecessary and even unwanted. Americans are about half way as 46% of their transactions feature cash as credit card use and mobile payment options expand. Even with concerns about data breaches and identity theft, a world without cash seems inevitable, if not imminent.

In Sweden Tomorrow Happens Yesterday

  • With a population half the size of Los Angeles (10 Million) and a sophisticated IT structure, Sweden can pilot-test new developments, new systems, and new futures almost overnight. Ironically, 350 years ago it became the first country to issue paper money. Now it’s on its way to be the first to phase it out altogether. There are Swedes, however, that are fighting this trend. At the heart of this story are two men on opposite sides both named Björn. The first is Björn Ulvaeus, one of the B’s in the famous pop group named ABBA. He is also half the brains behind the Mama Mia franchise that has made him a very rich man. In 2008, his son’s residence was robbed. Ulvaeus knew that the stolen items would be sold somewhere for cash so he asked himself, “what if there wasn’t any paper money?”

Cash is Anonymous and Crime Requires Cash

  • The criminal economy depends on the anonymous, untraceable nature of cash. That explains why a lot of the cash in the world is unaccounted for. The World Banks estimate that about a third of the cash in most countries circulates underground. Take it away and thieves and drug dealers have no way to do business, and the shadow economy collapses. Ulvaeus has written widely on the subject and has gone so far to make the ABBA Museum in Stockholm a cash-free zone. As safe as Sweden is, it is always looking for ways to increase safety.

Just Swish It

  • About the same time the ABBA Museum opened, Swedish banks created the Swish mobile phone app. This lets ordinary people transfer money to each other by using their mobile phones. All you need is someone’s phone number. About half of the population is using it so far as are small businesses and even homeless people. Cash transactions fell from 40% in 2010 to 20% in 2014 and more than half of bank branches do not deal in cash. Bank robberies have fallen 70% during that timeframe. Muggings and robberies have dropped as there isn’t much incentive to rob a person or a business that doesn’t have any cash. Tax revenues are also soaring. Ulvaeus hopes other countries will follow Sweden’s example and imagines how great going cashless would be for countries like Greece.

Unexpected Consequences

  • A number of odd things have happened. There has been a claim of e-mugging, which happens when someone forces you to Swish them some money, which is easy to trace. Tourists picking up cash at the airport have complained about not being able to spend it. ATM vendors are getting so little business that they are removing many of them. People depositing cash where they still can are viewed with suspicion. Tellers question people with cash and this can be a problem for churches. Hacking is more of an issue than ever. There have been some issues, but nothing major yet.

Björn Number Two

  • On the opposite side of the cashless argument is Björn Eriksson, the former chief of Interpol. At 71, he is the same age as Björn Ulvaeus. He claims that the move to a cashless society is being pushed by the banks and credit card companies rather than the people. He is also concerned about corruption, deceit, and security risks. Cards and apps with their hidden fees make banks money whereas cash transactions do not. In fact, cash costs banks money as they have to count, handle, transport, guard, and count it again.

Swedish Nature

  • Swedes are not a cynical people. They like technology and trust their government and institutions. Most of them have been happy to renounce cash and for some, the changeover has hardly been noticeable. The seeming thoughtlessness of many Swedes concerns Eriksson. Last year he started Cash Uprising in order to save cash. His supporters are mostly rural, small businesses, and retirees. These are the people who find the disappearance of cash to be inconvenient. People who sell produce, for example, end up with cash their local back won’t take. When they drive to the nearest bank that does take cash, there are limits to what they can deposit at once. For some, the change happened so fast that they couldn’t plan for it.

The Downside of No Cash

  • Thanks to Eriksson, the Swedish parliament may vote on a bill to require banks to provide cash services and the head of Sweden’s central bank is on his side. The biggest losers in a cashless society would be the security guards that are hired to protect cash. There is also the issue that when you spend cash, you don’t have to give up personal information. Although muggings and thefts are down, identity theft has more than doubled, and this only counts the incidents reported to the police. Cyber criminals are more active and many consumers have yet to learn how to protect themselves. Eriksson believes that banks are hiding the fact that at this stage even they have lost a lot of money.

The US is Sort of Catching Up

  • High profile hacks of the magnetic strips on the back of credit cards at places like Target and Home Depot have resulted in American retailers switching to chip readers. The chips make transactions more secure and the Swedes have had them for more than a decade. When I was there in 2010 I couldn’t even buy gas for my cousin’s car as my card lacked a chip. When I returned in 2014 I made sure I had a chip, but getting it took some effort as my financial advisor didn’t even know what it was. The US version of Swish is also in the works, but it remains to be seen how it will be received. The US also has a ways to go in regard to consumer protection. For now, transactions in the US are stalled at about 50% cash. Don’t be surprised if many Americans cling to their cash with more tenacity than the typical Swede.

My Cousins Weigh In

  • Cousin Peter Stockholm (40’s): Lot’s of people are using Swish, both when it comes to transferring between private persons and for smaller cash transfers at markets, cafés, and events. Today we went to an event for kids and all payments (hot dogs, entrance fees, parking, etc) were possible to via Swish. Most smaller stores accept it and a most prefer it. Being Swedish means that you count on the government to take care of you. I like it a lot, it is very convenient and I never lack cash thanks to Swish. I am quite sure you need a population that blindly trusts the authorities. It would be harder for Greece. October last year we got new bills, 200 SEK, 50 SEK and 20 SEK. I still haven’t seen the 200 or the 50 so that’s how often I see cash these days.
  • Cousin Martin Borås Western Sweden (40’s): Everybody is using Swish here. It’s a great service that gained millions of users very fast. It’s very common if two friends lunch together, one paying the bill and the other “Swishes”‘ the debt. Swish is also used by all small sports clubs when selling candy, drinks, and hot dogs at games. In Norway, they have a similar service called Vipps.
  • Cousins Morgan and Kristina Borås retired (70’s): We use Swish as often we can. It’s a perfect way to pay for what we buy and also to transfer money to others. I think the banks like it too as they always try to earn/steal as much money they can. Unfortunately, some older people are not trusting Swish and still use paper money. I´m sure Swish will take over, but it takes a time to have some people accept it.

Conclusion

  • Ultimately, Sweden’s two Björns want the same thing: a safer society. They are not so much rivals and complements. Thanks to their efforts, the US can look to the Swedes for guidance. I have been traveling to Sweden periodically since 1980. Every time I go I see innovations that come to the US in time. In 2010 I helped my cousin take some items to the recycling center. I was amazed at how hi-tech it was along with the degree they expected ordinary people to sort and recycle just about everything. This month I helped my sister clean out her house, which required many trips to the local recycling center. What I saw was an operation that looked a lot like Sweden six years ago. Just like we need to look to places like Finland for innovations in education, we need to look to Sweden for innovations in just about anything. As a Swedish-American, I know my bias is showing, but at least you know where I’m coming from. Skål!

Dr. Doug’s Multimedia Talk: Resources for Schools

Wednesday, December 23rd, 2015

On December 23, 2015, I gave a presentation on social media for educators to the staff at the Unatego Central School District in Upstate New York. During the talk I referred to the references below that for the most part stand on their own. Enjoy and share with educators you know.

Put this in the wall: Don’t post ANYTHING, ANYWHERE that you wouldn’t want ANYONE to see EVER! That goes for email too. If an email or any post makes you angry, your best reply is “let’s talk — tomorrow.”

You did review digital citizenship and online behavior prior to sending the kids off on the winter break, didn’t you? Research shows an increase of incidents related to sexual content and a spike in the number of students observed for depressive, self-harm, and suicidal issues during this time. Do you know who has this responsibility in your school?

Social Media and Your Reputation

Social media gives EVERYONE (that includes educators) one more way to get in trouble. What kind of trouble? See
Dr. Doug’s slides from his social media talk – This is a pdf file.

I don’t advise 1:1 electronic communication with students. Let students post questions to a blog where all students can see the question and your answer. If inappropriate questions or comments come in, take them down and talk to the student in private.
How many kids don’t have access at home? Do you know who they are? Who teaches copyright issues? Have your read your school policy lately?

Social Media for Professional Development and Student Learning

Shouldn’t every educator have their own professional development plan? Social media can facilitate this.
