Need a mental break? Avoid your cellphone Using a cellphone to take a break during mentally challenging tasks does not allow the brain to recharge effectively and may result in poorer performance, researchers found.

Many of us check our phones during a break.

I do too.

But your brain stays "on".

Focus experts advise us to do nothing so we can recharge. Feels boring (it is!), but your brain will thank you.

Very cool study. LQ continues to publish top-notch pieces. Criterion: Wilma loves it!

♿ People with disabilities are discriminated against when applying for jobs.

Ask most employers, and they’ll say: “𝐖𝐞 𝐝𝐨𝐧’𝐭 𝐝𝐢𝐬𝐜𝐫𝐢𝐦𝐢𝐧𝐚𝐭𝐞.”

So we tested it. We sent 1,500 real job applications.

The result? 𝐎𝐫𝐠𝐚𝐧𝐢𝐳𝐚𝐭𝐢𝐨𝐧𝐬 𝐝𝐢𝐝 𝐝𝐢𝐬𝐜𝐫𝐢𝐦𝐢𝐧𝐚𝐭𝐞. There is a gap between what employers SAY and what they DO.

Not the smartest people become leaders. It’s the ones who talk the most.

This is known as the Babble Hypothesis.

👉 Their finding:
Regardless of intelligence or expertise, groups often pick the person who talks the most as their leader.

"People who nominate themselves to be in charge perform worse than managers appointed by lottery, in part because self-promoted managers are overconfident, especially about their social skills."

Cool new paper on #leadership!

Hoera! Een NWO Vici‑beurs!🎉

Miljoenen mensen kunnen ontsnappen aan armoede met hulp van de overheid, maar doen geen aanvraag voor bijvoorbeeld huurtoeslag.

Ze lopen tegen barrières aan. Ik noem dit welzijnsmuren: Welfare Walls.

Er zijn ook lichtpuntjes.

Werkgevers staan positief tegenover proefplaatsingen en trainingen.

Maar de vraag blijft: is dat genoeg om een structurele verandering te realiseren?

De inclusieve arbeidsmarkt is helaas nog ver weg.

𝟑. 𝐁𝐞𝐥𝐞𝐢𝐝𝐬𝐩𝐫𝐨𝐛𝐥𝐞𝐞𝐦
Veel organisaties hebben geen beleid voor het aannemen van mensen met een beperking.

𝟐. 𝐏𝐨𝐬𝐢𝐭𝐢𝐞𝐩𝐫𝐨𝐛𝐥𝐞𝐞𝐦
Werkgevers zien geen passende functies binnen hun organisatie.

Dus vroegen wij ons af:

👉 Wat houdt werkgevers tegen om inclusiever te werven?

In ons nieuwe onderzoek onder meer dan 500 werkgevers vonden we drie barrières:

𝟏. 𝐊𝐞𝐧𝐧𝐢𝐬𝐩𝐫𝐨𝐛𝐥𝐞𝐞𝐦
Werkgevers hebben onvoldoende kennis over regelgeving.

New article in JPART on administrative burdens.

We examine how collaborating with citizens can help break down such burdens.

The paper speaks to debates in public administration on policy design and citizen–state interactions.

💻 Laptops are great, but not during class. 💻

Laptops are the standard in classrooms. This needs to change.

New meta-analysis of 24 experiments shows that handwriting will lead to higher grades for students.

📣 Working from home results in lower performance ratings📣

Managers give lower performance ratings to teleworkers than to office workers, even when holding performance constant.

Female teleworkers face an even greater disadvantage.

We show that Digital Transformation Leadership comprises two dimensions.

First, a Strategic dimension: how managers develop a vision, foster collaboration, and consider public preferences.

Second, an Operational dimension: how managers guide employees, internal processes, and outputs.

Governments try to adopt new digital technologies.

However, there was no reliable way to measure how public leaders are directing such transformations.

We therefore validated a Digital Transformation Leadership scale.
