EU weert Amerikaanse cloud toch niet De geplande Europese wet over cloudbeveiliging (EUCS) is op flinke weerstand gestuit in Brussel. In de Raad van de Europese Unie hebben diverse lidstaten zich uitgesproken tegen het voorstel van de Eu...

Nederland beschermt Bonaire onvoldoende tegen klimaatΒ­verandering, zegt de rechter Nederland schiet tekort in het beschermen van Bonairiaanse landgenoten tegen de gevolgen van klimaatverandering. De rechter bepaalde vandaag dat de staat daarom onmiddellijk aanvullende maatregelen mo...

Doet de Nederlandse overheid genoeg om de inwoners van Bonaire te beschermen tegen klimaatverandering? Nee, zei de rechter vandaag. Om onze overzeese kustgebieden en koraalriffen te behouden, moeten we dus een nieuw klimaatplan opstellen.

Bruce Springsteen - Streets Of Minneapolis (Official Audio)
YouTube video by Bruce Springsteen Bruce Springsteen - Streets Of Minneapolis (Official Audio)

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good.

Mentaal welzijn is een linkse strijd Mentaal welzijn is geen privΓ©aangelegenheid, maar een politieke kwestie. En vooral een die links moet claimen.

"De crisis in ons hoofd is geen persoonlijk falen, maar het logische gevolg van beleid dat onzekerheid normaliseert en winst boven welzijn plaatst. Mentaal welzijn is politiek."

WTF!? 😱

So next time you read a study based on data from participants, your first question should be:

"Were these participants human?"

Text reads: About synthetic panels
Recruiting the right participants for a study can be difficult. You may not get the exact demographics you need, and the shorter the deadline, the less sure you can be that everyone will answer on time. One possible solution can be to use synthetic panels.

Synthetic panels are powered by a first party proprietary AI model developed here at Qualtrics. Our synthetic panel is trained on thousands of responses from a variety of demographic backgrounds in order to more accurately predict how certain populations would respond to a survey.

Our synthetic panel is based on the United States General Population, and is only available in English. This panel comes with ready-made quotas and target breakouts in order to represent your chosen population and make it easy to launch your survey right away.

Question-writing best practices
To get the most reliable and actionable results from synthetic audiences, consider these question-writing best practices:

Ask forward-looking and attitudinal questions.
Synthetic panels perform best with perceptions, preferences, and intent-based questions. For example, β€œHow likely are you to try…?”
Synthetic panels are less applicable for studies on past behaviors, detailed recall, brand recall, or awareness questions. For example, β€œWhen did you last visit…?”

Discussion
The current study aimed to conduct a meta-analysis of the TPB when applied to health behaviours which addressed the limitations of previous reviews by including only prospective tests of behaviour, applying RE meta-analytic procedures, correcting correlations for sampling and measurement error, and hierarchically analysing the effect of behaviour type and sample and methodological moderators. Some 237 tests were identified which examined relations amongst model components. Overall the analysis indicated that the TPB could explain 19.3% of the variance in behaviour and 44.3% of the variance in intention across studies. This level of prediction of behaviour is slightly lower than that of previous meta-analytic reviews which have found between 27% (Armitage & Conner, 2001; Hagger et al., 2002) and 36% (Trafimow et al., 2002)
of the variance in behaviour to be explained by intention and PBC.

Did you know that from tomorrow, Qualtrics is offering synthetic panels (AI-generated participants)?

Follow me down a rabbit hole I'm calling "doing science is tough and I'm so busy, can't we just make up participants?"

The Dutch government made a €2 billion deal with Tata Steel, the country’s largest emitter, to help it reduce its emissions.

The problem here? The €2 billion figure is incorrect.❌

We looked into the true costs of this deal and found they are much higher.
