Introduction – Exploring and Expanding the Political World Pioneered by Don T. Nakanishi

This essay provides an introduction to the late Don T. Nakanishi of UCLA, commenting on his legacy in the founding and development of Asian American politics as a field. It also offers an overview of the articles and dialogue essays included in this special PGI issue on Asian Pacific American Politics, the first of its kind in the nation

The Voting Rights Act and the Election of Nonwhite Officials

Voting Rights Act (VRA) is one of the most important—if not the most important—public policies developed over the last half century to increase access to the U.S. political system for people of color. The VRA also provides an important context for understanding the ascension of nonwhite groups into the elected leadership of the nation (Browning, Marshall, and Tabb 1984; Davidson and Grofman 1994; Menifield 2001; Mc-Clain and Stewart 2002; Segura and Bowler 2005; Bositis 2006). This essay assesses the present-day significance of the VRA for the political representation of communities of color by examining the implications of majority-minority districts and other key provisions in the VRA for the election of nonwhite officials in the beginning years of the twenty-first century

Women with endometriosis have higher comorbidities: Analysis of domestic data in Taiwan

AbstractEndometriosis, defined by the presence of viable extrauterine endometrial glands and stroma, can grow or bleed cyclically, and possesses characteristics including a destructive, invasive, and metastatic nature. Since endometriosis may result in pelvic inflammation, adhesion, chronic pain, and infertility, and can progress to biologically malignant tumors, it is a long-term major health issue in women of reproductive age. In this review, we analyze the Taiwan domestic research addressing associations between endometriosis and other diseases. Concerning malignant tumors, we identified four studies on the links between endometriosis and ovarian cancer, one on breast cancer, two on endometrial cancer, one on colorectal cancer, and one on other malignancies, as well as one on associations between endometriosis and irritable bowel syndrome, one on links with migraine headache, three on links with pelvic inflammatory diseases, four on links with infertility, four on links with obesity, four on links with chronic liver disease, four on links with rheumatoid arthritis, four on links with chronic renal disease, five on links with diabetes mellitus, and five on links with cardiovascular diseases (hypertension, hyperlipidemia, etc.). The data available to date support that women with endometriosis might be at risk of some chronic illnesses and certain malignancies, although we consider the evidence for some comorbidities to be of low quality, for example, the association between colon cancer and adenomyosis/endometriosis. We still believe that the risk of comorbidity might be higher in women with endometriosis than that we supposed before. More research is needed to determine whether women with endometriosis are really at risk of these comorbidities

First measurement of the |t|-dependence of coherent J/ψ photonuclear production

The first measurement of the cross section for coherent J/ψ photoproduction as a function of |t|, the square of the momentum transferred between the incoming and outgoing target nucleus, is presented. The data were measured with the ALICE detector in ultra-peripheral Pb–Pb collisions at a centre-of-mass energy per nucleon pair sNN=5.02TeV with the J/ψ produced in the central rapidity region |y|<0.8, which corresponds to the small Bjorken-x range (0.3−1.4)×10−3. The measured |t|-dependence is not described by computations based only on the Pb nuclear form factor, while the photonuclear cross section is better reproduced by models including shadowing according to the leading-twist approximation, or gluon-saturation effects from the impact-parameter dependent Balitsky–Kovchegov equation. These new results are therefore a valid tool to constrain the relevant model parameters and to investigate the transverse gluonic structure at very low Bjorken-x.publishedVersio

Resolving the strange behavior of extraterrestrial potassium in the upper atmosphere

It has been known since the 1960s that the layers of Na and K atoms, which occur between 80 and 105 km in the Earth's atmosphere as a result of meteoric ablation, exhibit completely different seasonal behavior. In the extratropics Na varies annually, with a pronounced wintertime maximum and summertime minimum. However, K varies semiannually with a small summertime maximum and minima at the equinoxes. This contrasting behavior has never been satisfactorily explained. Here we use a combination of electronic structure and chemical kinetic rate theory to determine two key differences in the chemistries of K and Na. First, the neutralization of K+ ions is only favored at low temperatures during summer. Second, cycling between K and its major neutral reservoir KHCO3 is essentially temperature independent. A whole atmosphere model incorporating this new chemistry, together with a meteor input function, now correctly predicts the seasonal behavior of the K layer

How AAPIs in Congress Responded to COVID-19

The 116th Congress is making history in representational politics with the highest number of AAPI legislators in U.S. history. However, AAPI legislators’ increased visibility comes at the same moment as white supremacist politicians and pundits racialize a global pandemic. How have AAPI legislators responded to the COVID-19 outbreak? Our findings provide preliminary support for our hypotheses that AAPI legislators are more likely to be sponsors of AAPI-targeted legislation and that AAPI women legislators are more likely to introduce bills targeting AAPI constituents than their male counterparts. In addition, AAPI women legislators as a whole are more likely to sponsor legislation to advance interests of the intersectionally disadvantaged than AAPI men legislators during our study period (February to mid-May 2020)
