The Happiest Workers are Self-Employed

conversation

It’s Wednesday my dudes, which means you’re likely midway through your work week. If you’re looking for a boost in productivity and happiness you may want to consider working for yourself. People who are self-employed report being happier than people who work for bosses in a recent in study about workplace happiness. Of course, being self-employed isn’t for everyone but if you’re looking for a change maybe it’s time to strike out on your own!

Professor Warr said: “Professional workers who are self-employed really value the autonomy they have. They have the freedom to innovate, express their own views, have influence beyond their own role and compete with other companies and people.

“They really get to use their own expertise, so don’t seem to mind working long hours. They can find meeting high standards really fulfilling.”

Co-author Professor Ilke Inceoglu added: “Being engaged in their jobs makes people feel energised and pleased with their own contribution.

“Measuring how engaged people are in their work is therefore a really useful way to gauge their wellbeing and shows we must move beyond just looking at job satisfaction.”

Safer Cities Stem from Active Communities

In the 1990s former New York mayor Rudy Giuliani popularized the broken window theory which is a zero tolerance approach to getting rid of crime. At first it proved successful and the approach spread, only later was it revealed that other factors were at work. Today, the solution to fighting crime and bringing life back to communities isn’t by cracking down on the people living there – it’s to empower them. In order to do this it means changing the streetscape from car-focused to people focused and giving people agency around what the spaces are redesigned for.

Busy streets have less crime

These surface-level environmental changes turned out to have profound economic and societal effects on this part of central Flint.

We surveyed residents there in 2014—before the intervention began—as well as in 2016 and 2017. We are now preparing the results of the Flint study for publication in an academic journal, but here’s a snapshot of our findings.

the coalition’s latest report, assaults decreased 54 percent, robberies 83 percent and burglaries 76 percent between 2013 and 2018.

This is Systemic Street Safety

The video above demonstrates how communities can transition from an unhealthy, vehicle focused, urban design to a healthy pedestrian design. Regular readers of this site know that streets designed for people are better for communities by making cities healthier and economically more productive. Cars are an clunky way to move people in cities so much so Oslo is banning cars, and other cities are making similar efforts around improving transportation. We know what we need to do to reduce needless deaths at the hands of car drivers, all we need is the political will.

If you’re in Toronto today then you can meet at city hall at 5:45pm to call on local councillors to stop pedestrian deaths.

This Flowchart Helps You Evaluate any Argument

Complex issues with multiple influential factors can be difficult to process for some. Three researchers from George Mason University and the University of Queensland decided to help people evaluate arguments by combining their own knowledge into one handy flowchart. The flowchart (above) is a great tool to help you think through any topic that you’re having difficulty with. The best part of the using the flowchart is that the more you use it the better you’ll get at reasoning through other’s arguments.

Step 3:  Determine Inference

Recall that we can make deductive or inductive arguments. Deductive arguments make their conclusion necessarily true or false. Inductive arguments merely make their conclusion more or less probably true — thus admitting the possibility that the conclusion is wrong. One way to test whether an argument relies on deductive or inductive inference is to check whether and how its premises support its conclusion.

Don’t Give up on Desalination

How we manage local water sources drastically alters how we grow crops and get drinking water. Cape Town is currently experience a water crisis that was in the making for decades because of poor water use policies. Desalination plants can help coastal cities provide water to their populace by separating salt from seawater. Wired has a good article on how one company is improving desalination techniques for growing crops, which, they predict can help bring plant life to arid regions.

The structure’s double-layered fibreglass roof transmitted sunlight but captured heat, diverting it through ducts into a compartment at the building’s rear. There, the heat was used to distill freshwater out of seawater for irrigation. The rest was vaporised and sucked through the growing space by fans to cool and humidify the plants, reducing transpiration. Paton calculated that a square metre of crops adjacent to the greenhouse would have required eight litres of water per day to offset what they lost in transpiration. “But inside we were using closer to one litre per square metre per day, and we were growing a better crop.”

Paton is also interested in the long term restorative benefits of his invention. Davies’ model predicted that the greenhouse’s cooling and humidifying effect would seep into the surrounding environment: “You can see there would be a plume of cool air coming off the greenhouse,” he says. And since the region hasn’t always been barren, Paton thinks greenhouses could return parts of it to the naturally vegetated state it was in before overgrazing and drought took hold. “I believe that when you get to, say, 20 years, you’d have enough vegetation to do the job of the greenhouses because they’re creating shade and shared humidity – changing the climate.” Because vegetation sequesters carbon, that also has broader ramifications for mitigating the effects of climate change.
