Bayesian analysis of human movement curves

Summary.  We consider the Bayesian analysis of human movement data, where the subjects perform various reaching tasks. A set of markers is placed on each subject and a system of cameras records the three-dimensional Cartesian co-ordinates of the markers during the reaching movement. It is of interest to describe the mean and variability of the curves that are traced by the markers during one reaching movement, and to identify any differences due to covariates. We propose a methodology based on a hierarchical Bayesian model for the curves. An important part of the method is to obtain identifiable features of the movement so that different curves can be compared after temporal warping. We consider four landmarks and a set of equally spaced pseudolandmarks are located in between. We demonstrate that the algorithm works well in locating the landmarks, and shape analysis techniques are used to describe the posterior distribution of the mean curve. A feature of this type of data is that some parts of the movement data may be missing—the Bayesian methodology is easily adapted to cope with this situation.     

Early 20th-Century Career Counseling for Women: Contemporary Practice and Research Implications

The authors critically examine the development of career counseling for women during the early 20th century. The development of career counseling for women lagged behind career counseling for men. Challenges, such as feminization of occupations, restricted occupational opportunities, and societal norms, stunted the development of career counseling for women. Furthermore, career counseling for women varied based on racial groups. Early writings discussed opportunities specifically geared toward White, college-educated, nonimmigrant women. Although these beginning opportunities provided formal guidance to White women, many other women were excluded from formal career counseling and are not represented in these writings. Implications include training practitioners to recognize their own biases when working with women, how gender bias influences career counseling inventories and career theories, and how counselors can challenge these biases and stereotypes to provide the full range of career opportunities to women. Future research should address the impact of career counseling on women of color.
