Recoil and Threshold Corrections in Short-distance Cross Sections
We identify and resum corrections associated with the kinematic recoil of the
hard scattering against soft-gluon emission in single-particle inclusive cross
sections. The method avoids double counting and conserves the flow of partonic
energy. It reproduces threshold resummation for high-p_T single-particle cross
sections, when recoil is neglected, and Q_T-resummation at low Q_T, when
higher-order threshold logarithms are suppressed. We exhibit explicit resummed
cross sections, accurate to next-to-leading logarithm, for electroweak
annihilation and prompt photon inclusive cross sections.Comment: minor modifications of the text, some references added. 51 pages,

Scarier than the flu shot? : The social determinants of shingles and influenza vaccinations among U.S. older adults.
BackgroundAlthough more than half of older adults receive the annual influenza vaccine (flu shot), only about one-third have ever been vaccinated for shingles. With this in mind, our study examines how the associations between sociodemographic characteristics, health behaviors, and vaccine uptake differ between these two viruses. In doing so, it also investigates whether the social predictors of shingles vaccination changed after the rollout of a new vaccine in 2017.MethodsData come from the 2017 and 2020 waves of the Behavioral Risk Factor Surveillance System survey, using a subset of older adults aged 60-plus (N = 389,165). We use logistic regression models to test for associations between individual-level characteristics and vaccine uptake.ResultsOne, when compared to Whites, Black respondents had approximately 30 % lower odds of having received the annual influenza vaccine (Odds Ratios [OR] = 0.72 [95 % CI 0.66-0.78] in 2017, and 0.66 [0.60-0.72] in 2020). For the shingles vaccine, these racial differences were starker (OR = 0.53 [0.48-0.59] in 2017, and OR = 0.55 [0.49-0.60] in 2020). Two, self-rated health was negatively associated with having received the influenza vaccine, but showed little relationship with shingles vaccination. Three, men were less likely than women to receive both vaccines in 2020 (OR = 0.88 [0.83-0.94] for influenza, and OR = 0.80 [0.75-0.85] for shingles). Four, older adults who abstained from alcohol were, generally, less likely to receive either vaccine, when compared to both moderate and heavy drinkers. Finally, we found that the release of a new shingles vaccine in 2017 (Shingrix) had little effect on vaccination prevalence or its social determinants.ConclusionThe importance of social groups, health, and health behaviors on vaccination status may be disease-dependent. This study also provides possible guidance to health care providers and health organizations looking to increase vaccine uptake among older adults, which may have more urgency since the arrival of COVID-19
Let’s Drink to Being Socially Active: Family Characteristics, Social Participation, and Alcohol Abuse across Mid- and Later-life
Researchers and practitioners often extol the health benefits of social relationships and social participation for older adults. Yet they often ignore how these same bonds and activities may contribute to negative health behaviors. Using data from the Wisconsin Longitudinal Study (16,065 observations from 7,007 respondents), we examined how family characteristics, family history, and social participation predicted three measures of alcohol abuse between ages 53 and 71. Results indicate that, generally, greater social participation is associated with increased drinking days per month. We also found that religious participation and having ever lived with an alcoholic are each associated with reporting possible alcohol dependence but not with alcohol consumption itself. Lastly, we identified gendered associations between marital dissolution and drinking behavior. These findings contextualize the increasing rates of alcohol abuse among older adults by emphasizing the possible negative consequences of “linked lives” on health via relationship stress and group norms
