Extensive wildfires can have profound impacts on fauna communities by altering the vegetation structure and resource availability. However, unburnt areas within a fire mosaic may be important habitat for wildlife while the surrounding area recovers after fire. To understand the importance of unburnt vegetation for reptiles, we studied community assemblages at 15 burnt and 15 unburnt sites in a subtropical woodland 12 months after a 25 000 ha wildfire. We tested the relative importance of unburnt areas and structural attributes on reptile abundance, richness, and community composition across this landscape. Unburnt areas had higher species richness and diversity, but not overall abundance. Reptile community composition differed significantly between burnt and unburnt areas. Woody debris, which was retained in unburnt areas but depleted in burnt areas, was positively associated with increased reptile diversity and richness. Our results suggest that unburnt areas are vital for maintaining reptile diversity and richness within a woodland landscape after wildfire. These findings demonstrate the importance of ensuring fire management programs retain unburnt patches of vegetation in fire‐prone landscapes to sustain reptile communities. [ABSTRACT FROM AUTHOR]

Within the field of relationship science there is increasing interest in the connections between close relationships and physical health. In the present study, we examined whether adolescents' (~12 years old) and young adults' (~20 years old) perceptions of their parents as a secure base prospectively predict C-reactive protein (CRP), a commonly used marker of inflammatory activity, at age 32 in a well-characterized sample of African Americans. We utilized existing data collected as part of the Maryland Adolescent Development in Context Study (MADICS) to construct measures of perceptions of parental secure base support (SBS), general parental support, and peer support in early adolescence and early adulthood. In the present study, SBS was operationalized as the perceived ability to depend on parents in times of need. Fifty-nine African American MADICS participants who reported on perceived support in early adolescence and early adulthood participated in a follow-up home visit at age 32 during which serum CRP was measured via a blood draw. After controlling for inflammation-related confounds (e.g., tobacco use, body mass index), adolescents' perceptions of parental SBS, but not peer support or general parental support, predicted lower CRP values at age 32 (b = -.92, SE = .34, p < .05). None of the support variables in early adulthood predicted CRP at 32 years. This study adds to a growing literature on relationships and health-related outcomes and provides the first evidence for a link between parental SBS in adolescence and a marker of inflammatory activity in adulthood.

Perceived racial discrimination (PRD) has been associated with altered diurnal cortisol rhythms in past cross-sectional research. We investigate whether developmental histories of PRD, assessed prospectively, are associated with adult diurnal cortisol profiles. One-hundred and twelve (N=50 Black, N=62 White) adults from the Maryland Adolescent Development in Context Study provided saliva samples in adulthood (at approximately age 32 years) at waking, 30min after waking, and at bedtime for 7 days. Diurnal cortisol measures were calculated, including waking cortisol levels, diurnal cortisol slopes, the cortisol awakening response (CAR), and average daily cortisol (AUC). These cortisol outcomes were predicted from measures of PRD obtained over a 20-year period beginning when individuals were in 7th grade (approximately age 12). Greater average PRD measured across the 20-year period predicted flatter adult diurnal cortisol slopes for both Black and White adults, and a lower CAR. Greater average PRD also predicted lower waking cortisol for Black, but not White adults. PRD experiences in adolescence accounted for many of these effects. When adolescent and young adult PRD are entered together predicting cortisol outcomes, PRD experiences in adolescence (but not young adulthood) significantly predicted flatter diurnal cortisol slopes for both Black and White adults. Adolescent, but not young adult PRD, also significantly predicted lower waking and lower average cortisol for Black adults. Young adult PRD was, however, a stronger predictor of the CAR, predicting a marginally lower CAR for Whites, and a significantly larger CAR for Blacks. Effects were robust to controlling for covariates including health behaviors, depression, income and parent education levels. PRD experiences interacted with parent education and income to predict aspects of the diurnal cortisol rhythm. Although these results suggest PRD influences on cortisol for both Blacks and Whites, the key findings suggest that the effects are more pervasive for Blacks, affecting multiple aspects of the cortisol diurnal rhythm. In addition, adolescence is a more sensitive developmental period than adulthood for the impacts of PRD on adult stress biology.

Racial/ethnic (R/E) socialization is widely practiced in R/E minority families. However, only recently have models been developed to understand how parents' R/E socialization messages influence adolescent development. The primary goal of the present study was to clarify and extend existing work on R/E socialization in African American (Black) families by distinguishing between parent and youth reports of parents' R/E socialization messages and examining the extent to which adolescents and their parents agree about these socialization messages. In addition, we tested a theoretical model in which parent-reported R/E socialization messages have an indirect effect on the development of youth R/E identity through youth reports of their parents' R/E socialization messages. Using a combination of open- and close-ended data from a longitudinal study of self-identified Black adolescents and their parents, we found statistically significant parent-youth agreement about whether parents send both general R/E socialization messages and, for daughters, specific R/E socialization messages. R/E socialization messages focused on promoting cultural pride and history were associated positively with R/E identity development, whereas messages focused on preparing youth for discrimination tended to be unrelated to R/E identity development. The results largely supported the hypothesis that parent reports of parents' R/E socialization messages are related indirectly to the development of adolescent R/E identity via youth reports of parents' R/E socialization messages.

The present study used multidimensional and person-centered approaches to identify subgroups of adolescents characterized by unique patterns of behavioral, emotional, and cognitive engagement and examined whether adolescent developmental outcomes varied as a function of different combinations of engagement components. Data were collected on 1,025 youths (57% African American, 43% European American; 53% female, 47% male). Five profiles of student engagement in school were identified: Highly Engaged, Moderately Engaged, Minimally Engaged, Emotionally Disengaged, and Cognitively Disengaged. These 5 groups differed in their educational and psychological functioning. The study not only provides empirical evidence supporting the multifaceted nature of school engagement but also demonstrates its utility relative to educational success and mental health. Considering the multiple dimensions of student engagement simultaneously from a person-centered perspective promises a useful approach for addressing sample heterogeneity and understanding different patterns of school engagement and their consequences.

The present study examines growth curve trajectories of cigarette and alcohol use from 13 to 19 years, and investigates how family relations (i.e., decision-making opportunities, negative family interactions, and positive identification with parents) relate to contemporaneous and predictive alcohol and cigarette use during adolescence. Data came from a longitudinal study of European American and African American families from a range of socioeconomic backgrounds (n = 1160 for alcohol use; n = 1102 for cigarette use). European Americans had higher levels and faster rates of alcohol and cigarette use than African Americans. European Americans females had the greatest likelihood of increased cigarette use. Negative family interactions and positive identification had contemporaneous and predictive associations with alcohol and/or cigarette use. Negative family interactions were related to increased smoking and drinking, whereas positive identification was associated with decreased use. Family relations differentially affected cigarette use according to ethnicity and gender, but had similar effects on alcohol use. (Contains 4 tables and 2 figures.)

Consistent with the aims of this special issue, we present a systems perspective on self/identity, predicated on William James's classic distinction between "I" and Me, and use this perspective to explore conceptual relations between self/identity, motivation to learn, and self-regulated learning. We define the "I" self functionally in terms of the capacity for the conscious shifting and sustaining of awareness. The "I" is conceived of as that aspect of the self-system that affords the potential for the conscious and willful, rather than the non-conscious and automatic, motivation and regulation of behavior. We introduce contemplative education as a set of pedagogical practices designed to cultivate conscious awareness in an ethical-relational context in which the values of personal growth, learning, moral living, and caring for others are nurtured. We discuss the implications of contemplative education for the cultivation of conscious and willful forms of learning and living among students and educators alike.

Does anticipated future racial discrimination undermine African-American adolescents' academic motivation and performance? Do face-to-face experiences with racial discrimination at school undermine African-American adolescents' academic functioning? Does African-American ethnic identity buffer these relations? This paper addresses these questions using two waves of data from a longitudinal study of an economically diverse sample of African-American adolescents living near Washington D.C. The data were collected at the beginning of the 7th grade and after the completion of the 8th grade. As expected, the experiences of day-to-day racial discrimination at school from one's teachers and peers predicted declines in grades, academic ability self-concepts, and academic task values. A strong, positive connection to one's ethnic group (our measure of ethnic identity) reduced the magnitude of the association of racial discrimination experiences with declines in both academic self-concepts and school achievement. Most youth responded to anticipated future discrimination with increased academic motivation.

The authors' approach to using pattern-centered analyses and longitudinal data addresses how configurations of personal and contextual factors forecast the educational achievement and attainments of different youth across adolescence. Here, they discuss various types of pattern-centered analyses and provide an empirical illustration of how these techniques and longitudinal data can be used to explore how various psychological, behavioral, and contextual factors assessed in early adolescence are probabilistically associated with college enrollment rates among adolescents who complete high school.

Eccles (3) Abstract: This longitudinal study examines how extracurricular activity involvement contributes to 'educational resilience'-the unexpected educational attainments of adolescents who are otherwise vulnerable to curtailed school success due to personal- and social-level risks. Educationally vulnerable youth characterized by significant risks and an absence of assets were identified during early adolescence (approximately age 14) using measures of academic motivation, achievement, and mental health as well as family, school, and peer contexts. Using a mixture of variable- and pattern-centered analytic techniques, we investigate how both the total amount time that vulnerable youth spent in positive extracurricular activities and the specific pattern of their extracurricular activity involvement during late adolescence (approximately age 17) predict their subsequent enrollment in college during early adulthood (up through approximately age 21). Educational resilience was predicted uniquely by some, but not all, activity patterns. These results suggest that positive extracurricular activity settings afford vulnerable youth developmentally appropriate experiences that promote educational persistence and healthy development.

Peck (2) Abstract: In this overview of Volume 64, Issue 1, of the Journal of Social Issues, we describe why it is important to consider the diversity of student pathways through time and in context and why it is important to focus particularly on youth who defy predictions. We describe the ways in which expectations are formed in statistical analysis and also in real-world education systems and how the structural rigidity inherent in such systems can lead to poor person-environment fit for young people in education or training and to misleading statistical analysis. Our intention is to move beyond analytic approaches that assume 'one size fits all' while recognizing both that policy cannot provide fully individualized environments for everyone and that research cannot focus only on the unique characteristics of each individual. By focusing on individuals for whom our models typically do not apply, we highlight the value of research on complex but meaningful patterns of commonality among people, not in terms of the average person or effects, but in terms of coherent, distinct, and relatively homogenous subgroups of people experiencing systematic and consequential differences in their lives and lifepaths.

Peck (1) Abstract: ABSTRACT Terminological ambiguity and inattention to personal and contextual multilevel systems undermine personality, self, and identity theories. Hierarchical and heterarchical systems theories are used to describe contents and processes existing within and across three interrelated multilevel systems: levels of organization, representation, and integration. Materially nested levels of organization are used to distinguish persons from contexts and personal from social identity. Functionally nested levels of representation are used to distinguish personal identity from the sense of identity and symbolic (belief) from iconic (schema) systems. Levels of integration are hypothesized to unfold separately but interdependently across levels of representation. Multilevel system configurations clarify alternative conceptualizations of traits and contextualized identity. Methodological implications for measurement and analysis (e.g., integrating variable- and pattern-centered methods) are briefly described.
