The Politics of Latino Education: The Biases of At‐Large Elections

Abstract: This paper investigates the determinants and consequences of Latino political representation in the field of K-12 education. The first task is to examine the association between Latino population and the Latino presence on school boards. We then investigate if Latino representation is affected by the electoral structure of school boards, as scholars have reached differing conclusions on whether at-large and ward systems hinder or enhance minority descriptive representation. The next step examines the consequences of Latino representation, specifically whether board membership is associated with the share of Latino school administrators and teachers. The regression results show that Latino population positively affects Latino board representation, but that at-large systems hinder descriptive representation. The primary determinant of Latino administrators is Latino school board membership, and the primary determinant of Latino teachers is Latino administrators. In sum, at-large elections negatively influence Latino educational representation, which produces a ripple effect that ultimately reduces the share of Latino teachers.

Inoculating Against Reactance to Persuasive Health Messages

Abstract: This investigation examined the possibility of decreasing psychological reactance to health campaigns through the use of inoculation messages. It was hypothesized that an inoculation message, which forewarned of the potential of subsequent reactance, would decrease participants’ likelihood of reacting negatively to a freedom-threatening message aimed to reduce excessive alcohol consumption. Participants (N = 275) who were inoculated against potential reactance felt less threatened and experienced less reactance compared to those who did not read an inoculation message. Structural equation modeling showed that inoculation indirectly predicted lower intention to drink alcohol via the theorized mediated reactance process. This research suggests that it is possible to inoculate against self-generated cognitions that might otherwise lead toward negative health behaviors.

Life-history traits of the lizard Sceloporus undulatus from two populations raised in a common laboratory environment.

Abstract: Hatchling Sceloporus undulatus elongatus from Washington Co., Utah and S. u. garmani from Woods Co., Oklahoma were raised to maturity and reproduction under identical laboratory conditions with ad libitum food availability. Growth, allometry, age and size of maturity, clutch size and egg mass were compared among lab-raised cohorts from the two populations, among lab-raised and field-caught animals (including their field-caught mothers) and, for growth, with values obtained by previously published field studies on the same or nearby populations. For all traits population differences observed in previous field studies and current field samples resulted from both a plastic response to proximate environmental conditions and intrinsic (possibly genetic) difference. The most plastic traits were growth and age of maturity. Cohorts from both populations expressed the ability to mature in less than 6 months in the laboratory but only the S.u. garmani express early maturity in the field. Allometric differences generated during growth in the lab were not observed in field samples but may reflect an adaptive physiological difference. The least plastic trait was egg mass. The only trait for which the rank order of the difference in the field was reversed in the lab was growth rate. S.u. elongatus grew significantly faster than S.u. garmani in the lab but much slower in the field. The tendency of S.u. garmani females to breed at minimum size of maturity may be greater than that of S.u. elongatus.
