Sex-specific breeding ecology of common terns in N. E. England.

Bi-parental care is necessary in a wide range of avian species to successfully raise offspring. I investigated a range of topics relating to sex-specific breeding ecology in common terns Sterna hirundo, a monogamous seabird with negligible sexual size dimorphism. Subtle size differences can be utilised to identify the sex of terns, enhanced by within-pair comparisons which increased the accuracy and simplified computational procedures. Under natural conditions, parental contributions were found to be flexible with respect to adult quality and body condition. Males were also found to provision more efficiently and to deliver more energy to offspring than females. Therefore there was no evidence for females investing more than males during a breeding attempt. Parental favouritism with respect to offspring sex was found, although why this should have occurred is uncertain. Experimentally increased egg production highlighted adult quality as an important factor in determining clutch size. Experimentally increasing male body mass did not result in lower provisioning rates or chick condition, suggesting that this species has a greater buffering capacity than previously thought. Environmental sensitivity of male and female offspring was examined under natural conditions. Mothers produced more female offspring at the end of the laying sequence, and male chicks from these eggs had higher mortality than females. This suggests that gender influences environmental sensitivity, even without sexual size differences

Tracking of toddler fruit and vegetable preferences to intake and adiposity later in childhood

This study examined whether toddlers' liking for fruit and vegetables (FV) predicts intake of FV later in childhood, how both relate to childhood adiposity and how these were moderated by factors in infancy. Children in the Gateshead Millennium Study were recruited at birth in 1999–2000. Feeding data collected in the first year were linked to data from a parental questionnaire completed for 456 children at age 2.5 years (30 m) and to anthropometry, skinfolds and bioelectrical impedance and 4‐day food diary data collected for 293 of these children at age 7 years. Aged 30 months, 50% of children were reported to like eight different vegetables and three fruits, but at 7 years, children ate a median of only 1.3 (range 0–7) portions of vegetables and 1.0 portion of fruit (0–4). Early appetite, feeding problems and food neophobia showed significant univariate associations with liking for FV aged 30 m, but the number of vegetables toddlers liked was the only independent predictor of vegetable consumption at age 7 years (odds ratio (OR) 1.28 p < 0.001). Liking for fruit aged 30 m also independently predicted fruit intake (OR = 1.31, p = 0.016), but these were also related to deprivation (OR = 2.69, p = 0.001) maternal education (OR = 1.28, p = 0.039) and female gender (OR = 1.8, p = 0.024). Children eating more FV at age 7 years had slightly lower body mass index and skinfolds. An early liking for FV predicted increased later intake, so increasing early exposure to FV could have long term beneficial consequences

Associations of Parental and Peer Characteristics with Adolescents’ Social Dominance Orientation

Studies with adults of social dominance orientation (SDO), a preference for inequality among social groups, have found correlations with various prejudices and support for discriminatory practices. This study explores the construct among adolescents at an age when they are beginning to recognize the social groups in their environment, particularly adolescent crowds. The relationship of SDO and perceptions of parents’ responsiveness and demandingness were also investigated. Subjects were in grades 9–12 (N = 516, 53% female, 96% White). Mother’s and father’s responsiveness significantly predicted adolescent’s SDO scores, with greater perceived responsiveness associated with lower SDO. To analyze the multiple crowd memberships of the 76% belonging to more than one crowd, two-step cluster analysis was used to identify patterns, resulting in 8 clusters of distinct, heterogeneous composition. SDO differed significantly among males in different clusters, but not females. The importance of membership was positively associated with SDO among high-status crowds and negatively associated with SDO among the academic and normal crowds. The findings have implications for prejudices that may be developing in adolescence and indicate a need for further research into the social context of SDO and its development

The Challenge of Adolescent Crowd Research: Defining the Crowd

As research on adolescent crowds has increased over the past several decades, researchers appear to be confident in their claims of the consequences of crowd membership, even suggesting targeted interventions. This review of the various methods used to identify adolescents’ crowd membership suggests that this confidence may be misplaced. There are diverse methodologies used in this research area that examine different samples of adolescents belonging to each crowd. Social-type rating methods, self-identification methods, grouping by adolescent behaviors or characteristics, and ethnographic or other qualitative methods should be accompanied by greater specificity in terminology to alert researchers to the various phenomena being studied (i.e., “reputational crowd,” “interactional crowd,” “behavioral crowd,” “affiliation crowd”). Additionally, studies comparing the various self-identification approaches and peer ratings are needed, along with reliability studies of peer ratings. More attention to specific methodology to determine crowd membership and its stability will aid the design of theoretical models of adolescent crowds and contribute to developmental outcome research

Shaking Up Traditional Training With Lynda.com

Supporting the diverse technology training needs on campus while resources continue to dwindle is a challenge many of us continue to tackle. Institutions from small liberal arts campuses to large research universities are providing individualized training and application support 24/7 by subscribing to the lynda.com Online Training Library(r) and marketing the service to various combinations of faculty, staff and students. As a supplemental service on most of our campuses, lynda.com has allowed us to extend support to those unable to attend live lab-based training, those who want advanced level training, those who want training on specialized applications, and those who want to learn applications that are not in high demand. The service also provides cost effective professional development opportunities for everyone on campus, from our own trainers and technology staff who are developing new workshops, learning new software versions or picking up new areas of expertise from project management to programming, to administrative and support staff who are trying to improve their skills in an ever-tighter economic environment. On this panel discussion, you will hear about different licensing approaches, ways of raising awareness about lynda.com on our campuses, lessons learned through implementation, reporting capabilities, and advice we would give for other campuses looking to offer this service

Social and emotional components of book reading between caregivers and their toddlers in a high-risk sample

In this collective case study of caregiver behaviors with their toddlers, two-minute videotaped reading interactions were analyzed using a constant comparative method. Twenty-four caregiver—toddler dyads from a high-risk sample of children prenatally exposed to cocaine were selected from a larger sample because they represented the extremes of expressive language scores on the Reynell Expressive Language Quotient at 36 months, one year after the reading interactions. Caregivers in the high-scoring group shared control of the book and discourse, were ‘in tune’ with the child’s needs and abilities, and answered their own questions to the children. This was in contrast to the behaviors of caregivers of the low-scoring children, who appeared unaware of the child’s developmental needs in the interaction, particularly in their ability to respond to the questions posed. Implications of the results for future research on caregiver reading with young children are discussed

Tribal Disruption and Indian Claims

Legal claims are inherently disruptive. Plaintiffs\u27 suits invariably seek to unsettle the status quo. On occasion, the remedies to legal claims can be so disruptive-that is, impossible to enforce or implement in a fair and equitable manner-that courts simply will not issue them. In the area of federal Indian law, American Indian tribal claims not only disrupt the status quo but may even disrupt so-called settled expectations of those affected by the claims. The U.S. Court of Appeals for the Second Circuit has dismissed a round of Indian land claims at the pleading stage, includingOnondaga Nation v. New York, because it considered the claims so disruptive. We agree that Indian legal claims are inherently disruptive and may implicate the centuries-old settled expectations of state and local governments and non-Indians. It is empirically and categorically false, however, that the remedies tribal interests seek are impossible to enforce or implement in a fair or equitable manner. Every year in cases against state governments and their political subdivisions, Indian tribes settle long-standing claims that at their outset, often appear intractable, if not downright impossible, to remedy. The recent settlements of claims by the Oneida Indian Nation of New York, the Saginaw Chippewa Indian Tribe, and five Michigan Anishinaabe tribes demonstrate the falsehood of the idea that Indian claims are too disruptive to be remedied. These negotiated settlements powerfully illustrate that the disruption produced by Indian claims has an important function: forcing federal, state, and tribal governments to creatively seek solutions to difficult governance issues in Indian country
