As the political and social challenges facing the world multiply, the discipline of political science requires better tools and creative approaches advanced by a more diverse set of researchers. Yet the discipline has struggled to recruit and admit to graduate programs, and retain as faculty, women and underrepresented minorities. Many individual faculty, departments, and universities have developed innovative programs and sought to create structural changes to address these gaps. This article presents the approach taken by the Department of Government at Georgetown University: launching a week-long Political Science Predoctoral Summer Institute in 2022. We describe the Institute’s contours and structure, provide preliminary data on outcomes, and conclude by offering three ideas for expanding and advancing these types of initiatives across the discipline.

Social scientists with data science skills increasingly are assuming positions as computational social scientists in academic and non-academic organizations. However, because computational social science (CSS) is still relatively new to the social sciences, it can feel like a hidden curriculum for many PhD students. To support social science PhD students, this article is an accessible guide to CSS training based on previous literature and our collective working experiences in academic, public-, and private-sector organizations. We contend that students should supplement their traditional social science training in research design and domain expertise with CSS training by focusing on three core areas: (1) learning data science skills, (2) building a portfolio that uses data science to answer social science questions, and (3) connecting with computational social scientists. We conclude with practical recommendations for departments and professional associations to better support PhD students.

We present an elementary proof that the Rauzy gasket has Hausdorff dimension strictly smaller than two.

Cultivated sunflower (Helianthus annuus L.) pollen helps attract wild and managed bees needed to produce hybrid seed. Pollen quantity and grain size (≈quality) are affected by the environment, but are also heritable traits of interest for breeding. Florets from public inbred B-lines (maintainer) and R-lines (restorer) were used to evaluate pollen quantity and quality, test for trait correlations and determine if line development has changed pollen traits. Pollen quantity (≈25,000–67,000 grains per floret) and diameter (≈30–37 μm) were similar to previous reports and values of each parameter were correlated across years. Pollen quantity per floret was positively correlated with floret size (area; mm2) but floret sizes and pollen quantity were unrelated to pollen grain size. Groups of lines released relatively early (1968–1986) or late (1988–2006) did not differ in pollen quantity or size, and male (R-line) parents did not produce larger grains. The strong, positive correlation between floret size and pollen quantity reveals a possible trade-off because wild bees generally prefer sunflowers with shallower florets. The apparent lack of change in pollen quantity or pollen grain size over time (and lack of increased pollen size in R-lines relative to B-lines) suggests that the quantity and quality of pollen may not be limiting factors in the success of inbred lines or resulting hybrids. Though sunflower lines with larger florets contain more pollen, additional variation in pollen visible on sunflower heads may relate to the timing or completeness of pollen extrusion from anther tubes.

This article develops a liberal theory of the virtues in business. I first articulate two key liberal values embodied within market society: self-authorship and mutual benefit. Self-authorship is a mode of autonomy given expression through the effective exercise of economic liberties. Mutual benefit involves the intentional pursuit of the well-being of one’s transaction partners within economic exchange. These values are uniquely realized, I argue, within business, conceptualized as a distinct, firm-level, social practice. More specifically, individuals realize self-authorship by purposively integrating cospecialized resources, forms of knowledge, and business functions to facilitate mutually beneficial transactions. Through their commitment to mutual benefit, businesspersons establish ongoing, cooperative relationships with customers, members of other firms, and various stakeholders more generally. These relationships are constitutive of a distinct liberal notion of the common good. The practice of business and the common good in a market society are sustained by a range of individual-level virtues. I recount these virtues and, before concluding, discuss several other theoretical implications of this account.
