Bates College is a private liberal arts college located in Lewiston, Maine, in the United States. The college was founded in 1855 by abolitionists. Bates College is one of the first colleges in the United States to be coeducational from establishment, and is also the oldest continuously operating coeducational institution in New England. Originally a Free Will Baptist institution, Bates is now a nonsectarian institution.Bates College was ranked 19th in the nation in the 2015 US News & World Report Best Liberal Arts Colleges rankings. The college is listed as one of thirty "Hidden Ivies" and one of the "Little Ivies". Bates offers 32 departmental and interdisciplinary program majors and 25 secondary concentrations, and confers Bachelor of Arts and Bachelor of Science degrees. The college enrolls approximately 1,800 students, 300 of whom study abroad each semester. The student-faculty ratio is 9-to-1.Bates is a leader of the SAT optional movement for undergraduate admission. In 1984 it instituted one of the first test-optional admissions programs in the nation.

The major histocompatibility complex (MHC) is a polymorphic gene family associated with immune defence, and it can play a role in mate choice. Under the genetic compatibility hypothesis, females choose mates that differ genetically from their own MHC genotypes, avoiding inbreeding and/or enhancing the immunocompetence of their offspring. We tested this hypothesis of disassortative mating based on MHC genotypes in a population of great frigatebirds (Fregata minor) by sequencing the second exon of MHC class II B. Extensive haploid cloning yielded two to four alleles per individual, suggesting the amplification of two genes. MHC similarity between mates was not significantly different between pairs that did (n 1/4 4) or did not (n 1/4 42) exhibit extra-pair paternity. Comparing all mated pairs to a distribution based on randomized re-pairings, we observed the following (i): no evidence for mate choice based on maximal or intermediate levels of MHC allele sharing (ii), significantly disassortative mating based on similarity of MHC amino acid sequences, and (iii) no evidence for mate choice based on microsatellite alleles, as measured by either allele sharing or similarity in allele size. This suggests that females choose mates that differ genetically from themselves at MHC loci, but not as an inbreeding-avoidance mechanism. © 2012 The Royal Society. Source

Preterm infants often experience hyperoxia while receiving supplemental oxygen. Prolonged exposure to hyperoxia during development is associated with pathologies such as bronchopulmonary dysplasia and retinopathy of prematurity. Over the last 25 years, however, experiments with animal models have revealed that moderate exposures to hyperoxia (e.g., 30-60% O(2) for days to weeks) can also have profound effects on the developing respiratory control system that may lead to hypoventilation and diminished responses to acute hypoxia. This plasticity, which is generally inducible only during critical periods of development, has a complex time course that includes both transient and permanent respiratory deficits. Although the molecular mechanisms of hyperoxia-induced plasticity are only beginning to be elucidated, it is clear that many of the respiratory effects are linked to abnormal morphological and functional development of the carotid body, the principal site of arterial O(2) chemoreception for respiratory control. Specifically, developmental hyperoxia reduces carotid body size, decreases the number of chemoafferent neurons, and (at least transiently) diminishes the O(2) sensitivity of individual carotid body glomus cells. Recent evidence suggests that hyperoxia may also directly or indirectly impact development of the central neural control of breathing. Collectively, these findings emphasize the vulnerability of the developing respiratory control system to environmental perturbations. Copyright © 2012 Elsevier B.V. All rights reserved. Source

Calixarenes (CAs) and calix[4]resorcinarenes are cavity compounds, chiral analogues of which have the potential to be used as reagents for the differentiation of enantiomers in NMR spectroscopy. The nature of the substituent groups attached to the cavity permits the preparation of organic- or water-soluble analogues. In NMR applications, chirality of the CAs or calix[4]resorcinarene is usually achieved through the attachment of enantiomerically pure substituent groups. The use of inherently chiral analogues for chiral differentiation is less common. The range of CAs and calix[4]resorcinarenes that have been used for chiral analysis in NMR spectroscopy is reviewed. © 2013 Springer Science+Business Media Dordrecht. Source

Sex differences in children's toy play are robust and similar across cultures [1,2]. They include girls tending to play more with dolls and boys more with wheeled toys and pretend weaponry. This pattern is explained by socialization by elders and peers, male rejection of opposite-sex behavior and innate sex differences in activity preferences that are facilitated by specific toys [1]. Evidence for biological factors is controversial but mounting. For instance, girls who have been exposed to high fetal androgen levels are known to make relatively masculine toy choices [3]. Also, when presented with sex-stereotyped human toys, captive female monkeys play more with typically feminine toys, whereas male monkeys play more with masculine toys [1]. In human and nonhuman primates, juvenile females demonstrate a greater interest in infants, and males in rough-and-tumble play. This sex difference in activity preferences parallels adult behavior and may contribute to differences in toy play [1]. Here, we present the first evidence of sex differences in use of play objects in a wild primate, in chimpanzees (Pan troglodytes). We find that juveniles tend to carry sticks in a manner suggestive of rudimentary doll play and, as in children and captive monkeys, this behavior is more common in females than in males. © 2010 Elsevier Ltd.

Objective: The present study explores the association between positive mental health or flourishing, depression, and engaged learning in undergraduates. Participants: Entering first year students (N = 428) at a liberal arts college. Methods: Students completed measures of depression, flourishing, substance use, and student engagement. Results: Based on Keyes' model of mental health, 1 69.1% of students were flourishing, 29.0% were moderately mentally healthy, and 1.9% were languishing. In addition, 21.8% of students had elevated depression scores, and these scores were highly correlated with languishing. Alcohol consumption and binge drinking were not associated with measures of mental health. However, certain kinds of student engagement were associated with flourishing. Conclusions: Results suggest more flourishing in this sample entering college than in previous studies of high school students or adults. Future research should explore flourishing in undergraduates in more diverse samples across educational institutions, and employ prospective designs. Copyright © 2011 Taylor & Francis Group, LLC.
