Shifting and persosting in the face of failure: Learning from what did not work
No full textSocial justice activism demands coordinated, concentrated efforts to move the needle in a positive direction. In the author's nine years as a social justice educator, he led multiple large- and small-scale projects for social justice within higher education. In many ways, those efforts failed to create a lasting impact. In the higher education ecosystem, they also took away time from the kind of promotable work which would benefit his case for tenure and promotion. Trying - and failing - to effect institutional changes left him emotionally, psychologically, and physically exhausted. Beyond that, he suffered from feelings of loneliness, exclusion, and lack of direction. For a long time, the author blamed himself for the failure to change the institution to be a place in which he felt comfortable. He also failed to cope with these negative experiences and emotions, often seething in frustration or anger or avoiding similar situations of vulnerability or creativity. It took years for him to remember and internalize lessons of persistence and shifting appraisals in order to maintain motivation for action and survive the stressors of working within an oppressive system.Published versio
Sex- and age-related differences in post-breeding molt phenology are phylogenetically and ecologically widespread in passerines
No full textAssessment of within-population variation in the timing and duration of molt is crucial to understanding how molt overlaps and interacts with other important phases of the avian annual cycle, including breeding and migration. We investigated the effects of sex and adult age on phenology of the post-breeding prebasic molt in an assemblage of migratory songbird species captured during banding operations at Powdermill Avian Research Center in southwestern Pennsylvania, USA. Across all species examined, males consistently initiated molt earlier than females (14 of 15 species), and young adults hatched the previous year consistently initiated molt earlier than experienced older adults (13 of 13 species). Sex also had a weaker but significant effect on molt duration, with females completing molt more rapidly than males in 67% of the species examined. Adult age, in contrast, had no significant effect on molt duration. A review of the literature indicates that similar patterns are observed in the post-breeding molt of passerines worldwide, with females showing delayed but more rapid molt in diverse geographic, phylogenetic, and ecological contexts. The delayed onset of post-breeding molt in female passerines probably reflects either (1) their generally greater reproductive effort in egg-laying, incubation, and brooding of young, or (2) sex-specific physiological constraints imposed by the shared neuroendocrine mechanisms that regulate both avian reproduction and molt. The shorter duration of post-breeding molt in females may partially reflect their smaller body size and shorter flight feathers. Earlier onset of molt in young adults probably reflects their worn retained juvenile plumage, lower probability of successful nesting, and early termination of their initial breeding season. Regardless of the causes, strong sex- and age-based differences in the phenology of post-breeding molt are likely to produce cascading trade-offs with other aspects of the songbird annual cycle, including the timing of breeding, late-season parental care, and migration.Published versio
