Abstract Females and students of non-dominant ethnicity are less likely to aspire to science careers. However, overcoming discrimination in science and chemistry is a challenging task, especially in vocational orientation. Thus, there is a need for strategies to support young women in their identity formation in science and chemistry. This article presents a scheme for supporting young women’s science identity formation in conversations about vocational orientation. The goal is to support young women in developing a positive attitude towards careers in chemistry. This attitude is part of cultural chemistry capital. The scheme was developed based on a study conducted as part of the project DiSenSu. Here, coachings for vocational orientation for young women in science and chemistry are provided, following the idea of Science in Public. In the coaching, the attitudes towards science and chemistry were determined using quantitative data. Based on these results, coaches conducted conversations with the participants. Qualitative analysis of 11 conversations revealed strategies coaches used to support young women in their vocational orientation. The study shows how the participants’ attitude towards careers in chemistry is used as a starting point for coachings. Also, it provides strategies that can be used to promote young women’s cultural chemistry capital.

Phenotypic variability in a population of cells can work as the bet-hedging of the cells under an unpredictably changing environment, the typical example of which is the bacterial persistence. To understand the strategy to control such phenomena, it is indispensable to identify the phenotype of each cell and its inheritance. Although recent advancements in microfluidic technology offer us useful lineage data, they are insufficient to directly identify the phenotypes of the cells. An alternative approach is to infer the phenotype from the lineage data by latent-variable estimation. To this end, however, we must resolve the bias problem in the inference from lineage called survivorship bias. In this work, we clarify how the survivor bias distorts statistical estimations. We then propose a latent-variable estimation algorithm without the survivorship bias from lineage trees based on an expectation-maximization (EM) algorithm, which we call Lineage EM algorithm (LEM). LEM provides a statistical method to identify the traits of the cells applicable to various kinds of lineage data.

As our nation and the global economy place an increased demand for science, technology, engineering, and mathematics (STEM) jobs, science educators must implement innovative approaches to pique precollege student’s interests in these careers. Pharmacology remains a relevant and engaging platform to teach biology and chemistry concepts, and this strategy applied over several months in the formal classroom increases science literacy in high school students. In order to improve the affordability and accessibility of this educational approach, we developed and assessed the impact of a short-term pharmacology day camp, ‘Pills, Potions, and Poisons’ (PPP), on high school students’ science knowledge and attitudes toward science careers. The PPP program was offered annually from 2009 through 2012, and participants spent 6 days learning about pharmacology and careers in the biomedical sciences. All PPP student participants (n=134) completed surveys assessing their basic science knowledge and science attitudes before and after the program. Students achieved significant gains in their science knowledge by the end (Day 6) of the PPP program (from 41% mean test score to 65%; p<0.001). In addition, the majority of participants agreed or strongly agreed that the PPP program positively impacted their attitudes toward science (p<0.001). This study provides evidence that a short-term pharmacology-centered science enrichment program can achieve significant gains in participant’s science knowledge as well as motivation and confidence towards science careers. Moreover, we report benefits experienced by the undergraduate, graduate, and professional pharmacy student teaching assistants (TAs, n=10) who reported improved communication skills and an increased interest in future educational work.   Type: Original Research
