Ozonlaget beskytter det biologiske liv ved jordens overflade mod skadelig
ultraviolet stråling fra Solen. Udledningerne af CFC-gasser, som nedbryder
ozonlaget, er aftaget væsentligt de senere år. Alligevel er det
problematisk at forudsige gendannelsen af ozonlaget i de kommende år,
ikke mindst på grund af den betydning klimaændringer kan have.
Det mest ekstreme eksempel på at ozonlaget nedbrydes, er det antarktiske
ozonhul. Men også Arktis bliver hårdt ramt af ozonnedbrydning nogle år.
Derfor har den nedre stratosfære, hvor ozonlaget befinder sig, været
genstand for mange videnskabelige undersøgelser, med det formål at
kvantificere ozonnedbrydningen og forstå de processer, der ligger bag.
I foredraget vil jeg fortælle om mit arbejde med målinger af og forskning i
stratosfærisk ozon. Jeg vil også fortælle lidt om min karriere,
hvordan det er at arbejde på DMI og hvordan, jeg synes, forskning og
familie passer sammen.
In 2005, a questionnaire among the 107 Ph. D. Students within the physics
division was performed, treating how the Ph. D. students think of themselves,
their supervision, the work environment, recruitment and gender issues. The
aim was to find out what measures that should be taken in order to increase
the number of women in physics.
Our study shows that it is crucial to announce Ph. D. positions properly
if an increase of the number of female Ph. D. students is desired. Many
departments leave it to the undergraduate students to approach the professors
and ask for an available position, but this and other studies show that
almost exclusively male students benefit from this method. Generally,
female students only ask for a Ph. D. position if they are encouraged to do so.
Female physicist often find the social environment at work troublesome.
They seldom feel that others appreciate their efforts at work and they don't
feel that their colleagues value them as persons. They are also, to a much
larger extent than their male colleagues, exposed to dominating techniques.
Many women have either been exposed to sexual harassment or have adapted
their behaviour in different ways (like being careful with clothes, who
they talk to and when they leave work) to avoid being exposed. During
events such as conferences, summer schools and work at experimental
facilities, women seem more vulnerable than usual; a major part of them
have bad experiences.
A larger amount of men than women want to continue within physics
research after the dissertation. Many women who have decided to leave
science refer to the social environment and lack of opportunities.
Another interesting finding is that men who are positive to more women
in science and to active measures to improve the situation, want to leave
academia to a larger extent than men who have a hostile or a negative
attitude towards women in science.
