Critics call out problems with encampment bill Advocates say Ontario’s proposed encampment bill will only make the homelessness crisis worse. CTV’s Alexandra Holyk explains.

The Ford government's anti-encampment bill won't help solve the homelessness crisis. All it will do is criminalize those who are already down on their luck.

We need more supports, not more stigmatization.

Does chewing gum release microplastics into our bodies? A new UCLA study says yes. TMU prof. Roxana Suehring notes we must now study what types of chemicals are released and their impact on our health.

GLMM FAQ

Was catching up with friend and talking about model selection and covariance structures (as you do). We ended up turning to @bbolker.bsky.social's fantastically useful FAQ document for mixed models here: bbolker.github.io/mixedmodels-.... If you use #Rstats and mixed models, that FAQ is your friend!

this was arguably the first modern misogynist mass shooting -- the shooter had been denied admission to the engineering program, blamed the women who'd been admitted, bought a gun legally, entered the school, and proceeded to shoot only women, letting men go free and unharmed

Das sind natΓΌrlich alles meine persΓΆnlichen Erfahrungen und Vermutungen. Aber es war leider so, dass ich z.B. wΓ€hrend des Ingenieursstudiums immer wieder von Profs hΓΆrte, dass Frauen nichts im Ingenieurwesen verloren haben. Wenn in den Unternehmen Γ€hnlich gedacht wird erklΓ€rt das auch die Statistik

3. Und gleichzeitig werden Frauen in Naturwissenschaften und Ingenieurwissenschaften leider weiterhin oft nicht ernstgenommen/ mΓΌssen sich mit Vorurteile auseinandersetzen. Das fΓΌhrt dazu, dass sich weniger Frauen auf diese Positionen bewerben oder lieber ins Ausland gehen.

2. An Hochschulen und im Staatssektor gibt es mehr Geisteswissenschaftliche Forschungsstellen und fΓΌr diese werden Frauen ΓΆfter eingestellt

Als deutsche Wissenschaftlerin, die Deutschland bewusst verlassen hat, habe ich da einige Ideen:
1. Die Hochschulen haben seit Jahren mehr und mehr weibliche Doktoranden und postdocs. Auf der Professorebene sieht das dann schon deutlich schlechter aus.

High Time Resolution Ambient Observations of Gas-Phase Perfluoroalkyl Carboxylic Acids: Implications for Atmospheric Sources Atmospheric formation of persistent perfluoroalkyl carboxylic acids (PFCAs) is a route to global contamination, including drinking water sources. We present high time resolution measurements of C2–C6 PFCAs in ambient air made over 6 weeks each in winter and summer 2022 in Toronto, Canada. Observations were made using chemical ionization mass spectrometry with acetate ionization, with care taken to avoid system contamination. Measurements of trifluoroacetic acid (C2 PFCA) are reported at 1 min time resolution, while those for C3–C6 PFCAs are at 10 min time resolution. Variations with time and relationships to meteorology and other pollutants show evidence of secondary formation of all observed PFCAs except perfluoropropionic acid (C3 PFCA). High time resolution data allow these unique observations, allowing for improved process and source understanding moving forward. Mixing ratios of TFA were larger than predicted from models that describe TFA formation from known precursors, indicating additional atmospheric sources of this molecule have yet to be identified.

Excited to share the first real-time atmospheric measurements of #PFAS! We measured using acetate-CIMS in Toronto and see no evidence for direct emission of PFCAs. Rather, we see most are atmospherically formed. PFCA precursors must be considered and reduced! pubs.acs.org/doi/10.1021/...
