Clarification on perceived Vs measured to public transit accessibility?

19 October 2023 0 9K Report

Dear researchers could you give me some research hints on what should I focus on the issue of perceived and measured(spatial) accessibility to public transit accessibility in developing countries (like Addiss Ababa,Ethiopia).

Can anyone help me with the administration of the "Mind the Gap" Scale for satisfaction with transition to adult care?

We are working on a study focused on adolescents' transition to adult care and are looking for a validated measure for satisfaction with the transition. So far the only measure that we have came...

Multinomial probabilities and confidence intervals - obtaining the CI of the reference category?

Hi, Some background to my question: I have fitted 1st order multinomial Markov models with covariates. Since all probabiilties (for each row of the transition matrix) sum to 1, I estimate only...

What is the detection limit of ED-XRF technique for transition metals in silicon ?

Hi everybody, please, can someone tell us if the transition metals (W, Fe, Ni, etc ...) in silicon destined for solar cell manufacturing can be detected by ED-XRF technique. Note that the...

Are there any thermochromic materials that reflect infrared light (~9000nm) at 10C and transmit infrared light at 25C?

So I know some metal-insulators (ex VO2) have thermochromic infrared-reflective properties, but most of these are insulators at low temperatures and conductive at high temperatures. Some...
