The reproduction of gender differences in early career choices and professional identity of young dentist in Finland

Introduction For over the last 20 years, approximately 70% of working dentists in Finland have been women. However, there is internal division of the profession along gender lines. Female dentists work more often in the public sector and male dentists in the private sector. The aim of this study was to investigate the gender differences in young dentists' early career choices, specialization plans, values and perceptions of professional identity. Materials and methods The data were taken from a national e-mail questionnaire study called "Young Dentist," which was sent to 458 dentists who had received their licence to practise dentistry in 2014-2016 from all four universities with dental curricula in Finland. A total of 52% young dentists (n = 238) answered the questionnaire. Results and discussion The results indicated that whereas female dentists were more likely to perceive themselves as comforters, social workers and health promoters, male dentists tended to perceive themselves as technicians. These professional identities were interrelated with early-stage career choices in which female dentists worked more often in the public than in the private sector when compared to male dentists. There were also clear gender differences in the importance of values and the specialization plans of the young dentists. Conclusion Young dentists in Finland make career choices and develop professional identity in accordance with the attributes traditionally associated with cultural ideals related to femininity and masculinity.Peer reviewe

Concentration Dependence of the Effective Mass of He-3 Atoms in He-3/He-4 Mixtures

Recent measurements by Yorozu et al. (S. Yorozu, H. Fukuyama, and H. Ishimoto, Phys. Rev. B 48, 9660 (1993)) as well as by Simons and Mueller (R. Simons and R. M. Mueller, Czhechoslowak Journal of Physics Suppl. 46, 201 (1976)) have determined the effective mass of He-3 atoms in a He-3/He-4 mixture with great accuracy. We here report theoretical calculations for the dependence of that effective mass on the He-3 concentration. Using correlated basis functions perturbation theory to infinite order to compute effective interactions in the appropriate channels, we obtain good agreement between theory and experiment.Comment: 4 pages, 1 figur

Single Particle and Fermi Liquid Properties of He-3/--He-4 Mixtures: A Microscopic Analysis

We calculate microscopically the properties of the dilute He-3 component in a He-3/--He-4 mixture. These depend on both, the dominant interaction between the impurity atom and the background, and the Fermi liquid contribution due to the interaction between the constituents of the He-3 component. We first calculate the dynamic structure function of a He-3 impurity atom moving in He-3. From that we obtain the excitation spectrum and the momentum dependent effective mass. The pole strength of this excitation mode is strongly reduced from the free particle value in agreement with experiments; part of the strength is distributed over high frequency excitations. Above k > 1.7$\AA$^{-1}$ the motion of the impurity is damped due to the decay into a roton and a low energy impurity mode. Next we determine the Fermi--Liquid interaction between He-4 atoms and calculate the pressure-- and concentration dependence of the effective mass, magnetic susceptibility, and the He-3--He-3 scattering phase shifts. The calculations are based on a dynamic theory that uses, as input, effective interactions provided by the Fermi hypernetted--chain theory. The relationship between both theories is discussed. Our theoretical effective masses agree well with recent measurements by Yorozu et al. (Phys. Rev. B 48, 9660 (1993)) as well as those by R. Simons and R. M. Mueller (Czekoslowak Journal of Physics Suppl. 46, 201 (1996)), but our analysis suggests a new extrapolation to the zero-concentration limit. With that effective mass we also find a good agreement with the measured Landau parameter F_0^a.Comment: 47 pages, 15 figure
