What’s Most Likely To Kill Your Online Community?

by Richard Millington

You know the saying, first they ignore you

There are relatively fixed stages of doom for most communities.

1) You don’t notice the new trend (a shift to new technology, member launching a rival community, decline in topic popularity, collapse in internal support).

2) You ignore or dismiss the trend (“it’s a fad”, “he doesn’t have the support”, “our topic is strong” or “Mr. Smith has our back”).

3) You fight against the trend. You persuade people your technology is better, you attack your rival, you try to promote the topic, or you try to gain internal support. But it’s usually too late.

We all know what comes next.

The best time to prepare for this is right now.

1) If there is a sudden shift to a new technology, it’s better to move sooner than later. Go with the trend. Move to that app, launch the community on Reddit/Facebook as well, and speak to members regularly about how they participate in topic discussions. It’s incredibly hard (for you) to walk away from a platform in which you’ve invested so much. It’s far harder to see all your members walk away from you.

2) Preempt members launching a rival community. Rival communities form from an unmet need or disillusionment (a common scenario is when a community removes a feature members like). Provide a system for anonymous feedback for members to highlight what they want from the community.

3) Use data to check for topic popularity. How many people are searching for relevant terms each month? How many unique, new, visitors are reaching your community? How many people are showing up to events and participating in research? How many list the job profession in their profile? If you notice a decline, broaden the focus of the community or launch new communities in related areas.

4) Notice the signs of falling internal support. If your boss seems less interested in communities, if your budget is cut (or not increased), if you aren’t getting much attention internally, this is a problem. You need regular meetings with your boss (always a good practice) and other stakeholders. Understand what value they need and communicate how they’re getting it.

None of this is easy, which is why so many communities fall victim to one of the above. If you move quickly, many kinds of community deaths are entirely preventable.

Compositional machine learning

Some random notes I wrote for myself.

If you give a person a bunch of abstract images or videos, they can probably place them into some sort of categories with no supervision. The brain has a certain level of domain-agnostic raw signal processing and classification ability. Kind of interesting, though not magical.

Then there is also some further feedback—humans go out into the world, and then act based on these categorizations. Depending on outcomes, we then refine these categorizations. For instance, we might “naturally” put two items in different categories, but various forms of feedback from the world encourages us to place these items in the same category. (Think: a face during the day and at night is “the same” face) You could call this a form of “supervised learning”, but not exactly. Traditional supervised learning is too “clean”. In the real world, humans learn from much smaller and badly-labeled “training sets”—the feedback from the world isn’t “this assigned label was wrong” and the world certainly doesn’t tell us what categories there are in advance. It’s more like: “you put these things in the same category. Then XYZ happened. Now what?” Your brain does something useful.

Also, feedback from the world may encourage the brain to further distinguish among items given the same label. “Both these inputs are ‘a face’” needs further refinement and becomes “This is Alice” and “This is Bob”.

And theres’s quite a bit of fluidity here. The brain can switch between different means of categorizing the same inputs. We can adapt granularity “this is a face” vs “this is Alice” and also categorize according to different dimensions. “These pictures are taken at night” and “These pictures are taken during the day” (for the same pictures).

Lastly, the brain’s organization seems highly compositional. You learn one categorization task, and the next one becomes that much easier. Certainly in the obvious ways—-if you learn one written language, much of the classification logic of the brain seems to get recycled is able to be used for learning another written language. You learn one programming language, and you recycle most of this when learning another. It seems that “higher layers” of different networks are shared. But even in less obvious ways, rather abstract forms of reasoning get learned and recycled across classification tasks.

So the brute force approach to machine learning, where we build one neural net, train it for one task using a giant pile of data, then throw it out and use a completely different huge pile of data to train for what humans recognize as a similar task… it does not seem very practical. I suppose if you are Google or Facebook and can assemble these enormous training sets from user data for one narrow task like face recognition, well then that’s great, but it probably doesn’t teach us much about algorithms for supporting more general intelligence.

Part of the problem here is that a trained neural net is a black box. We wouldn’t even know how to reuse some parts of it meaningfully for some other task.

Any form of machine learning which starts with anything other than raw bits as input feels like “cheating” and teaches us less about how the brain works. By starting with something other than raw bits, we aren’t necessarily forced to understand the most general form of the brain’s compositional structure, and we aren’t forced to discover algorithms that learn this compositional structure. Instead, you can just feature engineer until your starting point is so close to the finish line that it almost doesn’t matter what learning algorithms you use.

If our brain starts with essentially raw bits as input and derives all these high-level classifications, with almost no supervision whatsoever, only various forms of feedback from the world, then our artificial systems ought to be able to the same. And getting an artificial system like this to do anything useful at all would probably teach us more.

David Brooks, What a Failed Trump Administration Looks Like

Brooks makes the case that even if Trump is not pushed from office by Russiagate, his administration won’t be able to get anything done, because the vast rule-based bureaucracy of the federal government will reject his personality-based governance.

Working together for critical thinking in schools

files/images/image-20150525-32558-q4csn1.jpg


Peter Ellerton, The Conversation, Feb 20, 2017


The focus of this article is critical thinking in the South African context, and in particular the recent Curriculum and Assessment Policy Statement (CAPS) and Thinking Schools South Africa (TSSA), "a non-profit organisation encouraging and resourcing the teaching of effective thinking in schools." One of the unsung advantages of critical thinking, writes Peter Ellerton, is that it creates resilience, promoting the development of "students who have an ability to think their way through problems, a confidence in their ability to do so, and who can apply critical thinking skills to understand their circumstances and explore options open to them."

Distance Education Price and Cost Report

files/images/DE_Costs_-_WCET_Report.PNG


Russell Poulin, Terri Taylor Straut, WCET, Feb 20, 2017


It's no surprise to anybody that distance and online courses cost students more (a least, when they're offered by traditional educational institutions). But more controversial in this WECT report (79 page PDF) is the contention that they cost more to produce. This result is based on 197 responses (from an unknown number of institutions) to an email survey sent to WCET members. Reading the results, the main reason distance education costs more seems to be "distance education costs more" (p.48). Every category of expense was higher for distance education. The main costs are faculty support and development (52%), tech (37%), and student support (28%). The report also makes the point that lowering cost isn't seen as part of the mandate by many institutions. Via Inside Higher Ed.

Annotate charts with a few clicks using ChartAccent

by Nathan Yau

Some say annotation is the most important layer for charts meant for public consumption. It directs readers where to look and what’s important. But the process is not always straightforward. ChartAccent is an application slash research project that aims to make annotation easier. Plug in some data, make a chart, and do some clicking and dragging. Done.

There are Two Types of Coaches. Which are You?

by djcoyle

Z-2When you look out at the vast ecosystem of teaching and coaching, you see two main species: people who are focused on building skill, and people who are focused on building people.

Most coaches and teachers are in the skill-building business. They spend their time thinking about how to get better. They understand technique and strategy and information. They specialize in the “how” — that is, giving people tools to improve.

People builders, on the other hand, are  focused not just on on skills, but on connecting with the learner and guiding the growth process. They use a toolkit of emotional skills to build relationships. They operate on a deeper level, specializing in tapping into the “why,” accessing the deepest wells of grit and motivation that drive progress over time.

Here’s a quick and wildly unscientific quiz to see where you fit:

  • A) I treat everybody as mostly the same
  • B) I treat people as individuals, with unique motivations, strengths, and weaknesses

 

  • A) I focus on drills and repetition
  • B) I focus on awareness and feedback, and helping the learner take ownership of the process

 

  • A) I focus on delivering the knowledge to drive improvement
  • B) I focus on building partnerships to create the knowledge together

 

  • A) I’m fascinated by designing drills
  • B) I’m fascinated by building plans, tools, and systems

 

  • A) I’m obsessed with progress
  • B) I’m obsessed with process

 

If you answered A) to most, you incline toward being a skill builder; if you answered B), you incline toward being a people builder. I think most of us would agree that being a people builder is probably a more powerful role to play. But what we might not appreciate is how simple it is to become one.

Here’s an example: the teachers at Geared to Golf Performance Center in Ontario started off a recent session by having the students answer a simple question: What is your motivational fuel as an athlete? They then shared the answers on this whiteboard.

C4kfVIBWQAAGase

It’s not exactly brain science; it probably took all of ten minutes to accomplish. But consider the effect: in one short exercise, the individual motivations of each learner are made apparent, both to themselves and to all the teachers. This isn’t just skill-building — this is partnering with the learner.

Another of my favorite people-building tools I’ve come across is KIPP’s framework for excellent teaching, which they use to guide their efforts to develop the talents of their teachers. It looks like this:

1441937402526-1

Check out the way it combines the various elements of teaching and centers all the them on student growth. This kind of model — as simple as it is — can be a powerful influence in a culture, because it places the skill sets in a social context. It connects people so they can grow together.

Do you happen to have any people-building tools or ideas you’d like to share? Feel free to share them below!

Authority figures in psychology spread more happy talk, still don't get the point that much of the published, celebrated, and publicized work in their field is no good

mkalus shared this story from Statistical Modeling, Causal Inference, and Social Science.

Susan Fiske, Daniel Schacter, and Shelley Taylor write (link from Retraction Watch):

Psychology is not in crisis, contrary to popular rumor. Every few decades, critics declare a crisis, point out problems, and sometimes motivate solutions. When we were graduate students, psychology was in “crisis,” raising concerns about whether it was scientific enough. Issues of measurement validity, theoretical rigor, and realistic applicability came to the fore. Researchers rose to the challenges, and psychological science soldiered on.

This decade, the crisis implicates biomedical, social, and behavioral sciences alike, and the focus is replicability. First came a few tragic and well-publicized frauds; fortunately, they are rare—though never absent from science conducted by humans—and they were caught. Now the main concern is some well-publicized failures to replicate, including some large-scale efforts to replicate multiple studies, for example in social and cognitive psychology. National panels will convene and caution scientists, reviewers, and editors to uphold standards. Graduate training will improve, and researchers will remember their training and learn new standards.

All this is normal science, not crisis. A replication failure is not a scientific problem; it is an opportunity to find limiting conditions and contextual effects. Of course studies don’t always replicate.

Annual Reviews provides an additional remedy that is also from the annals of normal science: the expert, synthetic review article. As part of the cycle of discovery, novel findings attract interest, programs of research develop, scientists build on the basic finding, and inevitably researchers discover its boundary conditions and limiting mechanisms. Expert reviewers periodically step in, assess the state of the science—including both dead ends and well-established effects—and identify new directions. Crisis or no crisis, the field develops consensus about the most valuable insights. As editors, we are impressed by the patterns of discovery affirmed in every Annual Review article.

On the plus side, I’m glad that Fiske is no longer using the term “terrorist” to describe people who have scientific disagreements with her. That was a bad move on her part. I don’t think she’s ever apologized, but if she stops doing it, that’s a start.

On the minus side, I find the sort of vague self-contragulatory happy talk in the above passage to be contrary to the spirit of scientific inquiry. Check this out:

National panels will convene and caution scientists, reviewers, and editors to uphold standards. Graduate training will improve, and researchers will remember their training and learn new standards.

What a touching faith in committees. W. H. Auden and Paul Meehl would be spinning in their graves.

Meanwhile, PPNAS publishes papers himmicanes, air rage, and “People search for meaning when they approach a new decade in chronological age.” The National Academy of Sciences is supposed to be a serious organization, no? Who’s in charge there?

The plan to rely on the consensus of authority figures seems to me to have the fatal flaw that some of the authority figures endorse junk science. How exactly do Fiske, Schacter, and Taylor plan to “uphold standards” and improve graduate training, when purportedly authoritative sources continue to publish low-quality papers? What do they say if Bem’s ESP experiment makes it into a textbook? Should psychology students do power poses as part of their graduate training? A bit of embodied cognition, anyone?

I really don’t see how they can plan to do better in the future if they refuse to admit any specific failures of the past and present.

Also this:

When we were graduate students, psychology was in “crisis,” raising concerns about whether it was scientific enough. Issues of measurement validity, theoretical rigor, and realistic applicability came to the fore. Researchers rose to the challenges, and psychological science soldiered on.

Yes, it “soldiered on,” through the celebrated work of Bargh, Baumeister, Bem . . . Is that considered a good thing, to soldier on in this way? Some of the messages of “measurement validity, theoretical rigor, and realistic applicability” didn’t seem to get through, even to leaders in the field. It really does seem like a crisis—not just a “crisis”—that all this work got so much respect. And did you hear, people are still wasting their time trying to replicate power pose?

And this:

A replication failure is not a scientific problem; it is an opportunity to find limiting conditions and contextual effects. Of course studies don’t always replicate.

Yes to this last sentence but no no no no no no no to the sentence before. Or, I should say, not always. To paraphrase a famous psychiatrist, sometimes a replication failure is just a replication failure. The key mistake in the above quote is the assumption that there was necessarily something there in the original study. Remember the time-reversal heuristic: in many of these cases, there’s no reason to believe the original published study has any value at all. Talk of “limiting conditions and contextual effects” is meaningless in the contexts of phenomena that have never been established in the first place.

If you want to move forward, you have to let go of some things. Not all broken eggs can be made into omelets. Sometimes they’re just rotten and have to be thrown out.

What's on the Horizon (Still, Again, Always) for Ed-Tech

The New Media Consortium and the EDUCAUSE Learning Initiative have released the latest NMC Horizon Report for Higher Education.

I have written quite a bit about the problems (as I see them) with the Horizon Report, most recently in a talk I gave last fall at VCU: “The Best Way to Predict the Future is to Issue a Press Release.” I have taken issue with the NMC’s refusal to revisit previous years’ predictions, for example, which is why I started a project where you can see at a glance how the predictions have and have not changed over the decade-plus of the Horizon Report’s existence. My project also makes some of the information available in a machine-readable format instead of solely in a PDF. (It seems like a missed opportunity to be touting “the future of ed-tech” in a report that is designed for the printer.)

This year, the Horizon Report’s Higher Education Edition does include graphics with some historical data, demonstrating how some technologies and topics appear and reappear and how some simply disappear altogether from the horizon.

Click for full-size

The topic names have been modified “for consistency,” the report’s authors say (although I’m a little unclear about some of these choices – how are “mobile learning,” “tablet computing,” and “bring your own device” separate technological developments? Why are “virtual assistants,” “learning analytics,” “adaptive learning technologies,” and “robotics” distinct from the overarching category of “artificial intelligence”?). Of course, the Horizon Report dates back to 2004, so this is only a partial look back at its own history. But the graphic still underscores (probably unintentionally) how haphazard the predictions about coming technological developments just might be.

Perhaps part of the problem is a compulsion to always pick something new simply for the sake of newness (for the newness of tech and for the continued relevance and circulation of the Horizon Report itself).

This year, the Horizon Report posits that the “Time to Adoption Horizon” for technologies in higher ed looks something like this:

One Year or Less

  • Adaptive Learning Technologies
  • Mobile Learning

Two to Three Years

  • The Internet of Things
  • Next-Generation LMS

Four to Five Years

  • Artificial Intelligence
  • Natural User Interfaces

Here’s what fourteen years’ worth of predictions look like:

Click for full-size

I can’t help but notice that mobile technologies have been one to three years out from widespread adoption since 2006. “Smart objects” (a.k.a. “the Internet of Things”) have been on the horizon since 2009. The LMS is now on the horizon for the very first time, despite being one of the oldest education technology systems out there, with origins in the 1970s and the development of PLATO. And gone from the horizon, these technologies from last year’s report: learning analytics, augmented reality and VR, makerspaces, affective computing, and robotics. Were they adopted? Were they rejected? The report does little to help us understand this.

Those technologies that are supposedly “on the horizon” have long been the primary focus and selling point of the report; but in 2014, it expanded its analysis, identifying the trends that might drive the adoption of education technology.

These are the trends the Horizon Report has identified this year:

One to Two Years

  • Blended Learning Designs
  • Collaborative Learning

Three to Five Years

  • Growing Focus on Measuring Learning
  • Redesigning Learning Spaces

Five or More Years

  • Advancing Cultures of Innovation
  • Deep Learning Approaches

These “trends” strike me as at once ahistorical and utterly meaningless – or even, as I described them in my VCU talk, “not even wrong.” “Measuring learning”? “Collaborative learning”? “Cultures of innovation”? How are these not already deeply intertwined with existing systems and practices of educational institutions? (Or is it, rather, that are these not intertwined in ways that further the ideologies underpinning a certain vision of a technologized future of education?)

The report also identifies certain challenges to ed-tech adoption – solvable, difficult, and wicked challenges – but these too seem to reflect a rather odd set of tests that higher education might face. There’s no mention of Trump and little discussion of state and federal education policies (accreditation, financial aid, for-profit higher education, DACA, Title IX, campus carry, for example). No mention of academic freedom (although, to be fair, there is a brief discussion of adjunctification). There’s very limited discussion of funding (that is, limited to discussion of “funding innovation” and not to funding higher education more broadly or to how students themselves will pay for post-secondary education or personal computing devices and broadband). Education technology in the Horizon Report is almost entirely stripped of politics, a political move in and of itself.

No doubt, I am asking the Horizon Report to do something and to be something that it hasn’t done, that it hasn’t been. But at some point (I hope), instead of a fixation on new technologies purportedly “on the horizon,” ed-tech will need to turn to the political reality here and now.

Paris deploys 'anti-migrant boulders' to thwart makeshift refugee camps

by jwz
mkalus shared this story from jwz.

City Hall has rolled in large boulders to dissuade migrants from setting up camps outside an official humanitarian centre.

The boulders appeared under a flyover at Porte de La Chapelle in the 18th arrondissement, of northern Paris, where migrants often sleep rough while waiting for one of the 400 spaces in the nearby official humanitarian welcome centre. [...]

The boulders are designed to make it hard for people to take shelter under the bridge, however those waiting for spots at the centre are managing to sleep in between the huge rocks.

"It's difficult to sleep here," one migrant told Le Parisien newspaper after the boulders were brought in.

This isn't the only piece of so-called "hostile architecture" Paris authorities have installed to stop migrants from making camps in the city.

After the camps at Stalingrad Metro was cleared, metal grills were erected blocking off areas where refugees had set up camps, such as along Avenue de Flandre and the Place de la Bataille-de-Stalingrad.

Previously, previously, previously, previously.

So how come we haven't heard much about the Chinese New Year home buying spree this year?

by Whisperer (noreply@blogger.com)
mkalus shared this story from Whispers from the Edge of the Rainforest.



So it's mid February and usually the real estate cartel is barfing out stories about how Chinese have come over to our shores on home buying trips for their kids.

It's become an annual tradition to hear this crap.  Here's just a couple of twitter posts from 2015/2014 to illustrate (click image to enlarge):


And with Premier Krusty gutting the Foreign Buyers Tax at the end of January (presumably it's news of this glorious move that's in those little red envelopes above), expectations soared that Cam Good's yellow helicopter might once again fly over the Lower Mainland.

In fact the Real Estate TV Network (RETV)... err... Global BC announced the wet coast's annual heralds of spring just three weeks ago...


Said Global BC:
"Vancouver’s slow-churning real estate market might see a slight uptick next week due to an influx of Chinese New Year vacationers. 
The Chinese national holiday – celebrated widely in Vancouver and around the globe – begins Friday night with a week-long holiday. Many take the time off as an opportunity to travel abroad. Last year, six million Chinese left the country for vacation.

Juwai.com, a China-based website for international real estate, says a quarter of Chinese consumers surveyed plan to travel internationally during Chinese New Year, with 42 per cent of those saying they plan to shop for property while away. In total, just under 11 per cent of all people surveyed said they’ll spend the holiday property hunting. 
The website also surveyed 163 realtors in Canada and found 17 per cent of international agents and 16 per cent of Canadian agents had been contacted by buyers who plan to visit during Chinese New Year. 
“We also see Vancouver getting a steady stream of Chinese visitors seeking a ‘lung cleansing’ holiday,” Charles Pittar, CEO of Juwai.com, said. “Canada is a top-five country for these trips. Other top lung-cleansing spots are Japan, Thailand, Australia and Switzerland. One-half billion Chinese were affected by hazardous smog this winter. They come to Vancouver for clean air, among other things.”
So how has the 'lung cleansing' gone so far this year?

Not that we have heard it on RETV Global BC, but reports are that Chinese New Year Sales of Vancouver Real Estate Are Down 78%.

Now besides debilitating Cam Good, an 80% drop in sales is nothing short of devestating. But the  drop in single family home sales - the bread and butter of the foreign Asian market - is even more spectacular. As the above article notes, "Sales of detached homes had the largest drop during this Chinese New Year vs the years prior. Just 119 sales were logged this year, an 87.28% decline from last year."

Yikes. And it's not just the detached market. Chinese New Year Condo sales are reported to be down 72% and townhouse sales down 78%.

Rumour amongst some agents is that pressure is being applied to the BC Liberals to cut what remains of the Foreign Buyers Tax, currently sitting at 15%, to something much lower.

We will see what happens next.

TransLink minister muses about a new kind of development tax to support transit … and mayors are worried

by Frances Bula

There’s been vague chatter for months now indicating that the province has its eye on the profits developers are making as they build towers next to SkyTrain lines (calling Derek Corrigan at Brentwood) as a possible source of revenue for big new spends on transit.

But TransLink Minister Peter Fassbender amped up the temperature on that lately by going public with talk about a “transit-supporting levy” that has been proposed (among other things) at a couple of roundtables he’s held recently.

Every mayor I talked to said it’s worth having the discussion about taking back some of the windfall land-value increase that developers get along those lines and using it for transit.

Surrey Mayor Linda Hepner said any discussion about a funding source that can be counted on as an ongoing and reliable source of transit money is worth having.

But the mayors are anxious. First off, they see that money as unequivocally theirs, not the province’s. They come up with the official community plans, they do the work of shaping where density will go, they take the heat from residents who don’t like those plans. They want control over that money to decide which community services it should go into.

Secondly, for cities like Surrey, the idea of adding on yet another tax to development, when it is struggling already to attract developers to its projected new downtown, is worrisome. My stories on this are here and here.

Mr. Fassbender said he doesn’t want to go into the cities’ piggy-bank and there is no discussion of where the revenue will go. But there are only a few options, as anyone can see.

The province can do what cities have asked for already last December, and create a new development cost charge whose money would be dedicated to transit. (Cities have that already for roads, water, sewer and park acquisition.) And then the province could say, Yes, all that money is yours. And since you have it, your share of all transit projects should be higher. (Currently, since the Trudeau government stepped in, the share is 50 per cent federal, 33 per cent provincial, 17 per cent municipal. The cities have said it should be 50/40/10, given the share of the tax pie each level has.)

Or the province could say, let’s talk about splitting it and we’re open to adjusting the share each of us pays based on that revenue.

Or it could just take part of it and use it for the standard 33 per cent it has always maintained is its fair share.

No one really knows which way this discussion is going. We await more news.

Choose Science

Government of Canada, Feb 19, 2017


Choose Science is a website recently created by the Government of Canada to encourage girls to pursue their interests (and may their careers) in science, technology, engineering and mathematics - STEM. It was  criticized by the National Post this week for perpetuating stereotypes (featuring fashion, music and kittens) but after a quick retrofit yesterday it is looking much better, though by no means perfect. The activities  for parents and  for teachers are drawn largely from  Actua and Let's Talk Science, which are private foundations with a lot of federal and industry funding. The resources could be a lot deeper and could be drawn from a much richer repository of actual work by Canadian teachers and educators. And instead of  talking down to girls interested in science, we should invite them to tell their own stories in their own voices. But hey - I'd rather see them do this work imperfectly than not at all.

NASA To Study Launching Astronauts on 1st SLS/Orion Flight

by Ken Kremer
mkalus shared this story from Universe Today.

KENNEDY SPACE CENTER, FL – In a potentially major change in direction for NASA’s human spaceflight architecture, the agency is officially studying the possibility of adding a crew of astronauts to the first flight of Orion deep space crew capsule and the heavy lift Space Launch System (SLS) rocket currently in development, announced Acting NASA Administrator Robert Lightfoot.

Lightfoot made the announcement in a speech to the Space Launch System/Orion Suppliers Conference in Washington, D.C. as well as an agency wide memo circulated to NASA employees on Wednesday, Feb. 15.

The move, if implemented, for the first joint SLS/Orion flight on Exploration Mission-1 (EM-1) would advance the date for sending American astronauts back to the Moon by several years – from the next decade into this decade.

Lightfoot has directed Bill Gerstenmaier, associate administrator for the Human Exploration and Operations Mission Directorate, to start detailed studies of what it would take to host astronauts inside the Orion EM-1 crew capsule.

“I have asked Bill Gerstenmaier to initiate a study to assess the feasibility of adding a crew to Exploration Mission-1, the first integrated flight of SLS and Orion,” Lightfoot said.

NASA’s current plans call for the unmanned blastoff of Orion EM-1 on the SLS-1 rocket later next year on the first test flight – roughly in the September to November timeframe from Launch Complex 39A at the Kennedy Space Center.

“The study will examine the opportunities it could present to accelerate the effort of the first crewed flight and what it would take to accomplish that first step of pushing humans farther into space,” NASA officials added in a statement.

But because of all the extra work required to upgrade a host of systems for both Orion and SLS for humans ahead of schedule, liftoff of that inaugural mission would have to slip by at least a year or more.

“I know the challenges associated with such a proposition, like reviewing the technical feasibility, additional resources needed, and clearly the extra work would require a different launch date” Lighfoot elaborated.

“That said, I also want to hear about the opportunities it could present to accelerate the effort of the first crewed flight and what it would take to accomplish that first step of pushing humans farther into space.”

Orion crew module pressure vessel for NASA’s Exploration Mission-1 (EM-1) is unveiled for the first time on Feb. 3, 2016 after arrival at the agency’s Kennedy Space Center (KSC) in Florida. It is secured for processing in a test stand called the birdcage in the high bay inside the Neil Armstrong Operations and Checkout (O&C) Building at KSC. Launch to the Moon is slated in 2018 atop the SLS rocket. Credit: Ken Kremer/kenkremer.com

The Orion EM-1 capsule is currently being manufactured at the Kennedy Space Center.

Secret Vancouver: Return to Hogan’s Alley

 .

Hogan’s Alley is an essential part of the history and soul of Vancouver. This vibrant, notorious neighbourhood was a magnet for famous entertainers (it’s where Sammy Davis Jr. learned to dance!). But it was also seen by 1960s city planners as an example of urban blight, and became the first few blocks destroyed to make way for a proposed 12-lane freeway.

We’ll view the short documentary Secret Vancouver: Return to Hogan’s Alley, followed by discussion with the director, Melinda Friedman, and featured contributor Wayde Compton.

Study: Will Quality of Portfolio Site Influence Hiring Decisions?

by Michael Keshen

Getting a job is all about impressing an employer by showing that you have what they’re looking for. The challenge is figuring out what exactly those things are. Even if your resumé checks off all the criteria in the job posting, these days that may not be enough.

Many of the domain names registered through Hover are used for professional portfolio websites, which our customers use to showcase their work and assist with finding employment. This got us wondering: will a portfolio site actually make a difference in the minds of hiring managers when vetting applicants?

We surveyed 121 people involved with hiring, from Coordinators to CEOs, to find out just how important a job candidate’s online presence is when it comes to getting a job offer.

So, how important is it to include an online portfolio in a job application? Here’s what we found:

Participants

Before we dive into the results, let’s first take a look at who we heard from. (Or, if you just want the results already, click here to jump ahead).

We received responses from all job levels of an organization, with the largest percentage identifying as Specialists (32%) and Managers (28%).

portfolio site importance survey - job level

In regards to how involved respondents are with hiring, a small sample (12%) indicated that they are not involved in the hiring process. Besides 5% of answers coming from Recruiters, responses were almost evenly split between Advisors (40%) and Hiring Managers (44%).

portfolio site importance - hiring duties

Next, we wanted to learn how long respondents have been involved in hiring. Overwhelmingly, responses came from individuals who have been hiring for 1-5 years (53%).

portfolio site importance - years involved with hiring

Finally, we wanted to get a feel for how many people our respondents are responsible for hiring. The majority of respondents indicated that they had hired 1-5 people within the past year (60%).

online portfolio importance - people hired in past year

We should also note that a majority of responses were from Hover customers, meaning that they own domain names. This may skew the results towards favoring online portfolios, as compared to the general population.

Online Portfolio Importance

Initially, it would seem as though an online portfolio is not so important after all. Although the majority of respondents either Strongly Agree or Agree that it’s important to have a portfolio site (38%), 31% feel Neutral about its importance, and 28% either Disagree or Strongly Disagree.

Employers will visit portfolio website

Despite their initial perception of portfolios, the story begins to change when asked about what happens when presented with a portfolio site. The vast majority of respondents (86%) either Agree or Strongly Agree that they will visit a portfolio when given the option.

online portfolio importance - will visit portfolio site

Portfolio site quality will influence hiring decision

Most revealing is what happens once employers arrive at a portfolio site. According to our survey, 71% of employers Agree or Strongly Agree that a portfolio’s quality will influence their decision on whether to hire a candidate.

Conclusion

Despite not being mandatory, having a strong portfolio site plays an important part in helping job applicants getting hired. This means that if you’re going to provide a portfolio site, make sure it’s of the best quality possible and makes you look great.

We shared the results with some leading HR professionals, and here’s what they had to say:

Jason Lauristenjasonlauritsen.com

“The results don’t surprise me. How you present yourself has always been critical to landing a job. It used to be the quality of the paper used to print your cover letter and resume and how you dressed for the interview. In our digital world, how you look online is critical. That said, I think the value of a portfolio website is linked to your profession. If you are a coder or designer, it makes perfect sense. If you are an accountant, probably not so much.”

Mark Anthony DysonThe Voice of Job Seekers Blog

“To have a personal website as your online portfolio is still the best way to stand out. Although employers do not make it a requirement, it does give them another opportunity to get to know you. Job seekers with online portfolios give employers another opportunity to know, trust, and like you will certainly increase their interest in you. The quality of your blog or website is essential. It is a preview of the quality of work you will deliver to them. If your blog is a deserted island with two blog posts in six months, it will not impress anyone. However, if it is a blog with consistent industry related articles published once a month, then you’ll increase your chance of interest.”

Nicole Le MaireNew To HR

“The hiring process is changing as the digital world is taking the next step. Recruiters are having to become more creative to fill vacancies, and the survey figures confirm what is happening in the workplace right now. With hundreds of job candidates for one role – the (only) way to stand out to an employer nowadays, is to create an online portfolio. It is like the candidate designs its own career story, directing the recruiter and hiring manager to their strengths, skills and experience. It creates a human link and is so much more personal than just the quick CV and cover letter introduction.”

If you’re ready to create your own portfolio website to land your dream job, get started by finding a great domain name!

A Few of My Favorite Apple Displays

by Stephen Hackett

Over the last 37 years, Apple has shipped 46 different models of standalone display.

The first was the Apple Monitor III, a green phosphor CRT built for use with the ill-fated Apple III.1


image via Wikipedia

The Apple Monitor III kicked off a long line of displays, but it's not all that interesting. Let's take a look at some of the standouts in a sea of forgettable beige products.

Apple IIc Flat Panel Display


image via Wikipedia

When Apple announced the Apple IIc in the spring of 1984, it also announced the Apple Flat Panel Display, a monochrome (1-bit) LCD screen designed specifically for the small machine.

The display was designed to make the IIc even more portable, but as it lacked any way to stay attached to the computer, users found it annoying to travel with the $595 accessory. The lack of a backlight, poor resolution (560 x 192 pixels!) and low contrast made it difficult to use except in very bright settings.

Macintosh Portrait Display

While the early Macs all came with built-in, 9-inch displays, the more powerful Macintosh II models required external monitors.

In March 1989, alongside the Macintosh IIcx, Apple introduced a 15" vertical CRT with a resolution of 640 x 870 pixels. It was aimed squarely at the desktop publishers that had become the Mac's bread and butter. The 80 DPI display was designed to show a full 8.5 x 11 inch page at once, making page layout easier and more efficient.

Apple wasn't the first to market with such a product; Radius beat Apple to the punch. This ad shows their product beside a Macintosh for scale:

AudioVision 14 Display

This is the tale of sorrow.

The Apple AudioVision 14 Display was a 14-inch display with an internal microphone, built-in speakers and more. It had a built-in micro-controller to communicate with the Mac over ADB.

Instead of a using separate ADB and video connectors, Apple opted for a single, proprietary connector named HDI-45. The 45-pin connector was only supported by a handful of computers, mainly the first-generation Power Macintoshes. An adaptor could be purchased to use a standard display with these Macs, but adapting to HDI-45 was impossible, stranding the AudioVision 14 Display on an island, forever doomed to be alone.

Apple Studio Display 15-inch

Now let's fast-forward past a whole bunch of consumer-grade "Multiple Scan" and professional "AppleVision/ColorSync" CRTs and join the future, as 1998 saw it.

The $1,999 Apple Studio Display 15 sat at the top of the range of several CRT options. Apple shipped three generations, and each one used a different display connector (DB-15, VGA and lastly DVI) and data connector, spanning from ADB to USB. At launch, it was paired with beige Macs, despite looking like it was designed for the more colorful Power Macs that would start shipping in January 1999.2

Apple Studio Display (17-inch ADC)

Based on looks alone, this may be my all-time favorite Apple display. I remember my high school yearbook staff having one, making all us newspaper kids jealous.

With that off my chest, just take a moment to look at this thing:

The clear case exposed the CRT far better than the translucent iMac G3s ever could. The contrast with the black material around the front of the CRT really made these things pop.

Under the covers, this was basically the same 17-inch CRT Apple had been shipping for three years. However, it now used Apple Display Connector (ADC), Apple's proprietary connector that carried video data (via DVI), USB and power all in one cable.

(ADC would stick around for several years, and enjoy a much more successful career than HDI-45, thankfully.)

In May 2001, Apple discontinued its last standalone CRT display. This generation of Studio Display was on sale for under a year.3

Apple Cinema Display

The Apple Studio Display 15-inch would mark Apple's entrance into the external LCD market, but the first few rounds of products would be confusingly named. For 1999 and 2000, Apple sold 17 and 21-inch CRTs with the all-new Apple Cinema Display at the top of the line with a whopping $3,999 price tag.

These displays would come to define the design language Apple would use for many years. Unlike that Studio Display above, these panels were encased in a minimal, transparent enclosure that made it look like the LCD was floating above the desk:

Apple shipped several sizes of these displays. The 1920 x 1200, 23-inch model was named the Apple Cinema HD display when it was released in March 2002.

In 2004, Apple revamped this lineup, introducing three new displays, at 20, 23 and 30-inch sizes clad in aluminum to better match the PowerMac G5:

The displays left ADC behind for good, moving to DVI, with USB and FireWire pass-through ports on the back of the display.

LED Cinema Display (24-inch)

In October 2008, Apple introduced the 24-inch LED Cinema Display. Powered by Mini DisplayPort and USB, it packed a built-in iSight camera, microphone and speakers in its new iMac-like case.

It was replaced with the larger 27-inch LED Cinema Display in 2010, which gave way to the Thunderbolt Display a year later. Until its cancellation in 2016, the design was basically unchanged from this 24-inch model.

A Dying Business

MacBooks and MacBook Pros far out-sell the Mac mini and Mac Pro, but it would be nice if Apple would have a good option for those customers when it comes to a display. Sadly, it seems those days are behind us.


  1. That's a story for a different time. ↩︎
  2. You can see several examples in the background of my photo, for example. ↩︎
  3. That makes it pretty hard to find this display today, as sad as that makes me. ↩︎

One way to protect Vancouver from land speculation: community land trusts

by Frances Bula

I used to hear the term “community land trust” about once a year. Now, I seem to hear about it almost every month.

Cities like New York and London are looking to community land trusts as a way to deal with the general real-estate insanity that appears to be prevailing in key cities around the world.

What are community land trusts? To use a definition scalped from one of the above articles:

A community land trust (CLT) is a model of non-profit land ownership in which a board of community stakeholders governs the use of land, while regulations ensure the permanent affordability of the rental or home-owner housing on that land.

Now a growing group of people in Vancouver are hopeful that this could become a more widely used model here.

As I note in my Globe story (which will appear in the Saturday print edition), the idea got a big boost here when the City of Vancouver turned over four valuable pieces of property worth $25 million to a group of non-profits and co-op housing to create a community land trust.

The group has started construction on the 358 units that will eventually exist, and which will function through a system of cross-subsidization. (The people who get the lovely condos fronting the river will pay max dollars, and their rent will help reduce the rent of someone in an apartment further away.) Warning: this system can’t bring rents down to a fully subsidized level. That would take provincial and federal help.

But it’s certainly an improvement from the unfettered market.

Thank you Guillermo Movia

by Emma

 

I first got to know Guillermo during our time together on Mozilla Reps council –  which was actually his second time contributing community leadership, the original was as a founding council member. Since this time, I’ve come to appreciate and rely on his intuition, experience and skill navigating complexities of community management as a peer in the community and colleague at Mozilla for the past two years.

Before I go any further I would like to thank Guillermo, on behalf of many,  for politely responding to terrible mispronunciations of his name over the years including (but not limited to)  ‘G-glermo, geejermo, Glermo, Juremo, Glermo, Gillermo and various versions of Guilllllllllmo’.

Although I am  excited to see Guillermo off to new adventures – I ,  and many others in the Mozilla community wanted to mark his 12 years with Mozilla by honoring and celebrating a journey so far.  Thankfully, he took some time to meet with me last week for an interview…

In the Beginning…

As many who do not speak English as a first language might understand, Guillermo remembers spending his early days on IRC and mailing lists trying to understand ways to get involved in his first language – Spanish.  It was this experience and eventual collaboration with other Spanish speaking community leaders Ruben and Francisco that led to the formation of the Hispano Community.

Emerging Leader, Emerging Community

Guillermo’s love of the open web, radiates through all aspects of his life, and history including his Bachelor’s thesis with a cover which you might notice resembles a browser…

During this same time of dedicated study, Guillermo began to both participate-in, and organize Mozilla events in Argentina.  One of his most memorable moments of empowerment was when Asa Dozler from Mozilla, who had been visiting his country, declared to Guillermo and the emerging community group  ‘you are the Argentina Community’ – with subsequent emails in support of that from both Asa and Mary Colvig that ultimately led to a new community evolution.

Building Participation

Guillermo joined Mozilla as staff during Firefox OS era, at first part time while he also worked at Nobox  organizing events and activities for De Todos Para Todos campaign.  He started full time not long afterwards stepping into the role of community manager for LATAM.   His work with Participation included developing regional leadership strategies including development of a coaching framework.

Proudest Moments

I asked Guillermo to reflect on what his proudest moments have been so far, and here’s what he said:

  1. Participation Mozilla Hispano creation community.
  2. Being part of Firefox OS launch teams, and localization
  3. Organizing community members, training. translating.
  4. Being part of the Mozilla Reps original council.

A Central Theme

In all that Guillermo shared, there was such a strong theme of empowering people – of building frameworks and opportunities that help people reach into their potential as emerging community leaders and mobilizers.  I think as a community we have been fortunate recipients of his talents in this area.

And that theme continues on in his wishes for Mozilla’s future – as an organization were community members continue to  innovate and have impact on Mozilla’s mission.

Thank you Guillermo!

Goodbye – not Goodbye!  Once a Mozillian, always a Mozillian – see you soon.

Please share your #mozlove memories, photos and gtratitude for #gmovia on Twitter and other social media!

Bike Spotting: How Has the City Been Doing With Bike Lane Maintenance This Winter?

by dandy

This year, the City of Toronto has committed to clearing priority bike lanes during winter. We went around the University of Toronto to ask cyclists what they think the service has been like so far.

Ginnie

Better than last year. A LOT better than last year. It hasn’t been perfect, there’s random chunks in the lane way. It’s not perfect we still have a ways to go.

Mike

I’ve found it pretty rough. I’ve had to bike in the lane itself.

Chris

It’s lacking.  It’s obviously been tough for the city. The private plows also create a lot of snow banks at the intersections, which is a problem.

Not Happy With The Bike Lanes This Winter? Suck It Up.

by dandy

The City is doing it's best to keep priority lanes clear this winter.

By Taylor Moyle

This winter, City of Toronto staff have been tasked with clearing certain “priority” bike lanes  -- with mixed results. Bikers aren’t completely happy  with the still-messy conditions in the bike lane, but the City is trying.

Bike lane maintenance has become a big issue in this city because people are actually using the bike lanes. In January, volunteers counted almost 2,000 trips per week on the new Bloor bike lane.

One of the biggest issues with the snow clearance is that snowbanks are being created at bike lane intersections after the plows (or cars from side streets) go through, which makes it unsafe for cyclists. Joey Schwartz says these messy intersections might be a deterrent for other cyclists, but not for him -- he rides every day.

Hector Moreno, manager of road operations for Toronto said that the snowbanks in the intersections is “never going to go away.” The snow has to go somewhere: It can’t be pushed back onto the laneway or roadway, so snow clearance from bike lanes and sidewalks can be labourious. Moreno added that because bikes don’t generate as much friction as cars and therefore don’t melt or break up the snow as much, it makes it more difficult for the city to deal with.

Despite bikers being unhappy, as seen with our bike spotting, Moreno does not think there is a “significant issue” with bike lane clearance this winter.

In the program's first year there are naturally going to be some bumps in the road, (or in this case snow) and the city is recognizing this, and they are trying to improve procedures based on what they learn this year. And, the City is trying new things too. Moreno described a pilot project the city recently started where a pull-behind trailer, with multiple wheels goes along all the dedicated bike lanes in order to agitate the snow which would make it melt faster. He also noted the trailer will be used on city sidewalks in the future.

Cars also push snow and slush over into the bike lanes, Moreno noted.

Laurie Featherstone, another year-round every-day Toronto cyclist noted this as a problem as well but does admit the lanes have been “pretty good” this winter.

She said that when there is a large snowfall, as we had in December, cars can spill slush onto the bike lanes and when it’s cold, it hardens. This makes the lanes practically unusable, rendering Featherstone to use the car lanes for “a couple of days.”

Moreno said that residents will sometimes put snow onto the bike lanes when clearing their own properties. And, although patrollers are 24/7 and can be deployed at any time, Moreno invited people to call whenever they do see a problem. Still, Moreno said people need to manage their expectations -- they can’t expect the city to respond in five minutes.

Toronto cyclist Chloe Hill says that the lanes do get plowed once, at first, but the city is doing a poor job at maintaining them after. “They don’t maintain it and it doesn’t go far enough. They’ll plow it once and then they’ll let it melt on its own,” said Hill.

Schwartz, along with Featherstone, think the issue can be fixed with two plowing sessions to clear the bike lanes. One at the usual time, and another several hours after to clear the remaining snow put on the road by civilians, cars, and snow plows, especially at intersections. Moreno said that there is no specific timing for the when the maintenance crew is deployed: They can be deployed any time of day, depending on need.

According to Moreno, about 66 units are dedicated to clearing the bike lanes. Overall, there are 200 road salters, 600 plows and 300 sidewalk machines that the city deploys to keep the roads clean in the winter season. That means about 17 per cent of the road units are dedicated to the 33 km of bike lanes the city has said it’s committed to maintaining during winter.

The city has also not taken any strategies specifically from Montreal, another city that gets lots of snow and bikers. Montreal does much more snow removal than Toronto.

At the end of the winter season Moreno and the city plan to sit down and evaluate how they did. There will be no public report, yet. Moreno said that might come in “two or three more seasons.” Moreno also noted that there is no official way for bikers to voice their input to the city on this matter. There are also no plans as of now for the priority bike lane list to be expanded.

Moreno said, “The city is committed to providing safe and passable conditions throughout the winter on the priority bike lanes.” Moreno also stressed that every winter is different and this one in particular has brought much more snow so far than previous winters. Despite the complaints Moreno seems satisfied with the service the City has provided so far this season. “We believe the program that we have in place is working fairly well,” he said.

Moreno said, “All of us need to do a better job at managing the expectation.”

Ours to own, not theirs to profit

by Michal Rozworski

It seems the public sector is under attack from all directions these days. Despite historically low public financing costs, despite proven efficiency and innovation, the public sector gets a bad rap in the public eye—something all manner of politicians from hardened right-wingers to cosmpolitan neoliberals take advantage of, letting markets further seep into the very functioning of health, education and other basic services.

I have two guests today to talk about the threats to public services and how to combat them. First, Chris Parsons, Coordinator of the Nova Scotia Health Coalition, talks to me the problems with public-private partnerships (P3s), and takes us on a tour of bungled P3 schools in Nova Scotia. Second, Adrienne Silnicki, National Coordinator of the Canadian Health Coalition, discusses the state of public healthcare in Canada, both the threats from the private sector and the ways to fight for a better public system.

Unbuilding the Wall

by Guest

This is a guest post by Toby Shorin.

Although symbols are intangible, that doesn’t mean they are inaccessible. On the contrary, we routinely understand and interact with the world by interpreting and intuiting their meanings. Symbols can be created, altered, proliferated, and overthrown.

This essay will discuss one symbol and its meanings: Donald Trump’s Wall. During the ‘15-‘16 election cycle, the Wall became as much of an aspirational motif for the right as it was a corrupt one for the left. In some ways, the Wall usurped Trump himself as the central image of the election. Compared to Trump, whose innumerable controversies make him an ethically difficult figure even for many of his supporters, the Wall makes a simple proposition: in or out. This legerdemain condenses a whole lineup of wicked problems and convoluted realities into a highly condensed ideological meme, representing the entire package of Trump’s policies. Ease of compliance is visible in the rally chants of Trump followers (“build the Wall, build the Wall!”), which acknowledge and perpetuate its myth.

Of course, the Wall is not just a symbol; it is a very real political project with significant implications. But symbols are not just ideas; they are very real concentrations of meaning with political agendas and the potential for momentous adoption. For example, the key symbol of the now-dead Occupy movement, “the 99%,” has been instrumental in spreading awareness of income inequality, and nearly 10 years later remains a crucial tool of global leftist discourse. In the apparently straightforward gesture of the Wall is hidden a similarly nuanced conceptual model. The Wall defines America by drawing its boundaries, producing an exclusionary, misleading, and compelling model nation. As a symbol, it functions on three levels: the geopolitical, the psychological, and the semiotic—it fucks with meaning itself.

Nostalgia for Sovereignty

Let’s start by taking Trump’s plan for the Wall at face value, and look at it as a territorial action. Trump claims that to “Secure Our Borders” from entry by immigrants, refugees, and terrorists, a Wall must be built, and policies like his immigration ban on Muslims enacted. This project is recognizable as a variant of the Brexit agenda in the UK, which went by a different but similarly themed slogan: “Take Back Our Nation.” Each program promises a sovereignty guaranteed by the territorial boundary of the state.

Ideologically, the Wall inherits the Westphalian model of sovereignty we all learned in high school. The preeminent authority on this model is 20th century legal theorist Carl Schmitt. Schmitt observed that before the legal, economic, and social structures of a state could emerge, there must always be an act of land appropriation. Because Westphalian sovereignty is also based on territorial ownership, Schmitt saw it as the ultimate spatial ordering method among various historical alternatives. The theoretical developments Schmitt made offer us two insights: first, that the Wall is a literal reinforcement of the Westphalian territorial model; and secondly, that its core ambition is to reinitiate the American legal, economic, and social orders.

Unfortunately, the legacy of the 20th century is the erosion of the territorial Westphalian model. The growth of transnational sovereign entities, multinational corporations and digital technology platforms, have rendered the idea of geographical sovereignties obsolete.

MNCs operate within countries but also stretch over national boundaries. They create alternative legal jurisdictions, active in both specific in-country sites where the corporation enforces its own disciplinary policies; and across a network of Special Economic Zones set up to accommodate free trade. The latter indicates an economic and legal order, the borders of which are not definite. This extra-national order is shapeless, but nevertheless present (for instance, in international arbitration courts in which MNCs and other private entities prosecute and sanction national governments). Other corporations cherish their national identities, but employ the majority of their workforce in other nations.

National sovereignty is further overwhelmed with the rise of digital citizenship. Increasingly, services conventionally guaranteed by the state are provided by private technology platforms. Traditional areas of state competency, like cartography and transportation, together with new services vital to daily life—digital storage, instantaneous communication, public knowledge, and so on—compose a suite of public services that these platforms compete to offer. Cloud-based platforms make multiple sovereign claims over the same people, events, and spaces, wrestling with and overlapping state’s own objectives (Bratton, 2016).

These are just a few among many transnational institutions that act like, and consider themselves, sovereign powers. The land-centric Westphalian model has has exhausted its relevance. The Wall, then, is an inherently nostalgic project, connected in spirit with Trump’s anti-globalist pledges. It suggests that America can retreat from this world of global finance capital flows and conglomerates. It alludes to the revitalization of “Greatness” and the return of jobs “back to America”—the Wall easily takes on the patriotic values and historical norms of the Westphalian model. Trump followers may not point directly to the decline of statehood, the rise of opaque megacorporations, and the inhumanity of a systems-based society as the culprits behind their dissatisfaction. But even when the issues are not explicitly identified, the Wall’s suggestion of a return to a more familiar form of society is alluring.

For followers of Trump, the Wall is a clear symbolic emblem for America’s restoration. The vision of an “impenetrable physical wall on the southern border” outlined in Trump’s campaign documents is a promise to reinstate the American sovereign order, and deny America’s embeddedness in international economic systems. The achievability of these objectives are beside the point. In the fantasy induced by the Wall, distribution and production are reverted back to their industrial-era modes, ending free trade and relocating labor back to America. A new American social order will be hewn, based on patriotism, and a statehood based on an imaginary homogenous identity of its residents. As an effective symbol, the Wall reflects—and creates—the desire to return to a simpler, normative understanding of geopolitics. One where sovereignty and “control” can be imposed on the world by defining and dividing it.

Masking Violence

Now we have a hint as to the Wall’s symbolic function. At the geopolitical level, the Wall obscures the actual workings of international political economy, refocusing attention on America, which it reinscribes by laying down borders. The imposition of boundaries to create some sort of “order” is something we’ll see again and again.

Above, we saw how a legal and social order is created through an act of territorial appropriation—a founding act of violence. The usefulness of violence does not end when a state is created, however. A state must maintain a monopoly on the use of violence to continually redefine its authority. Political theorist Willy Apollon (1996) says:

In our industrial and postindustrial societies, political power appeals to the sovereign use of violence, through the concern of the Law that establishes that sovereignty… In effect, political power is acknowledged as the authority that guarantees the society against a violent contradiction where its existence may be challenged. The power of that authority is legitimated through the political discourse that sustains the theory of Law defining the monopoly and the right of violence.

The United States of America is practically a case study on state-sponsored violence. Like other imperialist cultures before it, America displays an innate compulsion to dominate and exploit peoples and other nations. Its deployment of violence against non-white people is what is most relevant to our ongoing look at the Wall.

One success of the Black Lives Matter movement has been to expose how language and imagery used by the media legitimizes state violence against black American citizens. Following the death of a black person at the hands of the police, it is now common to see comparisons of the imagery selected to represent the deceased—often grainy pictures of the subject, unsmiling, looking somewhat menacing—with alternatives showing them smiling, laughing, with family, and so on. It has also become popular to identify and highlight language such as “thug” and “bad kid,” used by the media and the police to demonize victims and justify the actions of the police.

The state’s “right to violence” is always justified, both intentionally and unintentionally, by this dance between state institutions and public media. The dynamic is not new, nor does it exclusively utilize black, predominantly male Americans. State and media coordination during the Iraq War era focused on the supposed cultural captivity of the Muslim woman. And as with police violence against blacks in America, the last few years has seen a mainstream awakening to how the threat of terror has been invoked to legitimize persistent drone bombings in the Middle East. More recently, there has been criticism of the “job creation” rationale for what is ultimately violence against Native Americans in the struggle over the Dakota Access Pipeline.

If the Western political project is to establish a “mythical legitimacy for the monopoly of violence” (Apollon), that legitimacy is threatened by the growing general knowledge of how state and media collude to protect it. The most clear responses to the newfound obviousness of state violence come in the form of denial. The existence of “Blue Lives Matter” can only be read as evidence of mainstream, bi-partisan consciousness. The “Blue Lives Matter” narrative reverses the direction of violence to put police in the position of the victim, retroactively justifying police violence. Like “Blue Lives Matter,” the symbolic function of the Wall is to perpetuate denial. It represses collective social awareness of America’s violent reality.

Apollon reads political discourse as a “repression and substitute to the analysis and investigation” of the state monopoly on violence. In the psychoanalytic tradition, repression has two stages: innate violent and sexual drives are repressed, becoming fixations which then are projected outward. It is indeed striking how well this maps to Trump’s polemic, which has consistently denied racial bias while recentering the national narrative on a victimhood that justifies the Wall’s existence. The Wall portrays America an innocent entity, threatened by the entry of impure, darker-skinned others. Its claim to inviolability also seeds the notional possibility of violation. Fear of rape and murder are used to justify its existence. The Wall here acts as a border, dividing the American collective conscious from its collective unconscious. Just as the Wall hides international realities by venerating America, it obscures the target of violence, non-white-ness, while shifting the narrative so as to allow violence to continue unimpeded.

Importantly, it is not only penetration by foreigners that is fixated, but the threat of otherness—blackness, Hispanicness, Muslimness—within the national body itself. An important conclusion can be reached by following this logic. First, if coloredness is an impurity, then the collective identity of America produced by the Wall can only be understood as white. It is a sort of psycho-social order which defines the collective social mind, both figuratively and literally. As an infrastructural project, the Wall enacts what it symbolizes: the rejection of coloredness from the American social identity. The creation of the Wall is itself an act of psychological violence against Hispanic citizens, both documented and not. Trump’s immigration ban, increase in law enforcement and ICE staffing, and aggressive deportation policies are also best understood as measures to reduce the number of non-white people in America. But for the the Wall’s white proponents, this is all lost. It clears the white American conscious, while at once inflicting and obscuring its violence, and encouraging fear of non-white others.

The Final Symbol

Future semantic historians, delving into media from the 2010s, are sure to feel they have stepped into a war-ravaged landscape. In the 2010s, the logic first called “postmodernism” but properly termed poststructuralism has finally been acknowledged by the mainstream. The great legible institutions the state and the identity, have been overwhelmed, shown to be merely society’s constructions. The appearance of “post-truth” and “alternative facts” in mainstream political discourse indicates that the general public can now see that multiple meanings, far from impossible, are in play at all times. Post 2008 financial crisis, this is the war-zone of America. It has been spoonfed heaps of red pills and dogfed its own liberal vitamins. Is Trump’s election a triumph of white angst or of American pride? A foreign manipulation or the local failure of identity politics? Mastery of persuasion or meme magic? The air is thick with irreconcilable narratives, symbols, and herrings.

Unfortunately, traumatic events (such as the dissolution of absolute meanings) always incur responses. By my estimates, we’re somewhere between the “denial” and “anger” stages. Faced with confusing signals and the looming possibility of nihilism, drastic and violent attempts to re-impose truth on the world are becoming more and more frequent. Here, the ultimate mechanism of the Wall is revealed: it abolishes the inherent nebulousness of meaning altogether. Trump, claiming Nixon’s mantle as the “law and order candidate,” will lead us back to the rigidly ordered epistemology of structuralism.

In structuralist thought, it was thought that the symbols corresponded directly to their meanings, This representational pair, the “signifier” and the “signified,” were believed by structuralists to be how the brain’s language structure worked.

The crucial advancement of poststructuralism was to prove this false. Poststructural thinkers deconstructed language to show that there is no essential meaning affixed to each word, symbol, or idea; an idea only refers to (or “signifies”) many others. “Actual” meaning, then, is continuously deferred on and on, down an endless “signifying chain” of meanings. This is the essence of post-structuralism: meanings are not constant, not fixed, but flexible and co-created by their contextual use. America’s quickly-changing lexicon of youth slang proves the point rather well; 5 years ago, words like “lit,” “squad,” and “fire” did not have the accepted meanings they have today.

However, psychoanalyst and semiotician Jacques Lacan proposed the existence of a “master-signifier”. Among the endless chain of signs, the master-signifier asserts itself as an unquestionable constant, forming a stable, structured symbolic order. When a master-signifier emerges, all other meanings are defined in relation to it.

This special characteristic of the master-signifier is illustrated well in the anti-semitic thought of WWII-era Germany. There, “‘Jew’ serve[d] as the final word that effectively explains and accounts for everything…unifies a given field, constitutes its identity” (Gunkel, 2014, emphasis mine). This example shows how the signifier “Jew,” although empty of any fundamental meaning, came to possess a quality of absoluteness. Like other vague and indefinable yet ultimate words such as “good” and “evil,” invoking the “final word” forces everything else to relate to or against it. But because the master-signifier is as arbitrary and as empty as all other signifiers, it can only obtain primacy through an “abyssal, nonfounded, founding act of violence” (Zizek in Gunkel).

Do the circumstances sound familiar? A challenging reality, devoid of the comfortable assuredness of past absolutes; an act of order-creating violence, which justifies its own existence and obscures the truth. Today, the master-signifier is America; the Wall, the “violent imposition,” a territorial appropriation of meaning itself. Circumscribed by the Wall, America the concept achieves absolute significance. As satirized in the classic America, Fuck Yeah, “America” stands in to tautologically justify everything American and vilify everything un-American. Between the two there is no middle ground (“there is no alternative!”). The plan to build an impermeable Wall is a plan to build an essentialist hegemony of meaning.

Within this symbolic order, meanings are rendered in dualistic terms, forced to relate back to the master-signifier in a perverted form of structuralism. Good and evil, white and non-white, inside and outside the Wall. Each relate back to the “final” notions of American and un-American. One opposite is therefore always subordinated to the other in a “violent hierarchy” of terms. It is obvious that in this America, the privileged terms include citizen, documented, white, and male; the subordinated being foreigner, undocumented immigrant, nonwhite, and female. As exhibited by numerous instances of physical, psychological, and infrastructural violence against the latter groups in the weeks and months following Trump’s elections, the new politics of meaning is treacherously easy to internalize and enact.

This makes America and the definition of its semiotic boundaries the ground of deadly ideological conflict. We have arrived at the battlefront of the culture war over the meaning of America. On one side, an exclusionary meaning, defined from within the white mental model. For this side, the Wall is a powerful symbolic weapon that shrinks and ossifies America’s meaning, reversing the historical trend of an expanding definition of America and Americanness through emancipation, enfranchisement, and anti-discriminatory legislation. Regardless of political inclination, the informed reader will agree that the forceful imposition of national and psycho-social boundaries is totalitarian. On the other side, a definition of America that is more like meaning itself: permeable, inclusive, and most importantly, flexible. The natural workings of meaning are more like a distributed direct democracy, or perhaps even libertarianism. Meanings change and expand reflexively, and are responsive to the needs of their constituents and users. Eventually, the meaning of “America” may not even be limited to the country’s current geopolitical bounds.

A few words of advice for readers looking to join the resistance: opposition starts with better and more subversive meaning-making. Division has created the opportunity for unification through the creation of completely new symbols. Powerful words in the national vocabulary such as “freedom” and “liberty” are ripe for reinterpretation. For those with a platform, publicly acting in ways that challenge final vocabularies and hegemonic meanings is highly effective. Readers who wish to sharpen their weapons should practice deconstruction, analysis, and redefinition. If this essay has communicated one thing, it should be that wars are fought not only over meaning, but with it.

Bruno Snell, writing during and after WWII says: “when it is agreed that certain institutions have come to represent [the] absolute, the catastrophe becomes inevitable.” America may yet become that institution, and the Wall its real border. But the provocation to adopt absolute systems of meaning will always face resistance, for meaning is inevitably neither absolute nor nonexistent. It extends beyond our attempts to make it, arrives in unexpected places, and grows around Walls.

“First, [revolutionary actors] must de-legitimate the mechanisms that stabilize hegemonic meanings”
