Ethnic and Racial Identity in Adolescence: Implications for Psychosocial,Academic, and Health Outcomes

The construction of an ethnic or racial identity is considered an important developmental milestone for youth of color. This review summarizes research on links between ethnic and racial identity (ERI) with psychosocial, academic, and health risk outcomes among ethnic minority adolescents. With notable exceptions, aspects of ERI are generally associated with adaptive outcomes. ERI are generally beneficial for African American adolescents' adjustment across all three domains, whereas the evidence is somewhat mixed for Latino and American Indian youth. There is a dearth of research for academic and health risk outcomes among Asian American and Pacific Islander adolescents. The review concludes with suggestions for future research on ERI among minority youth.     

Feeling Good,Happy, and Proud: A Meta‐Analysis of Positive Ethnic–Racial Affect and Adjustment

One point of intersection in ethnic and racial identity research is the conceptual attention paid to how positively youth feel about their ethnicity or race, or positive ethnic–racial affect. This article reports results of a series of meta‐analyses based on 46 studies of this dimension and psychosocial, academic, and health risk outcomes among ethnic and racial minority youth. The overall pattern of results suggests that positive ethnic–racial affect exhibited small to medium associations (r range = |.11| to |.37|) with depressive symptoms, positive social functioning, self‐esteem, well‐being, internalizing, externalizing, academic achievement, academic attitudes, and health risk outcomes. Implications for theory and research about the role of positive ethnic–racial affect among youth growing up in an increasingly diverse society are discussed.     

Performance monitoring of university research: A perspective from Australia

The purpose of this paper is to report on who creates branding within institutions of higher learning, and what impact branding has on core institutional activities such as student recruitment and fundraising, as well as on socio‐psychological factors such as community respect and national prestige. Eighty‐nine tertiary education experts covering three world regions were surveyed in order to gather information to fulfil the paper’s objectives. The nature and extent of involvement of enrolled students, alumni, higher management, external consultants, civic leaders and the business community were investigated to identify the part each plays, if any, in the development of an institutional brand. Findings indicate that institutions have a tendency to brand from the top down rather than from the bottom up.     

Picture Book Biographies for Young Children: A Way to Teach Multiple Perspectives

In today’s global age, it is important for young students to develop multiple perspectives. Some of the standards that today’s teachers are required to adhere to include an understanding of different cultures. The National Council for the Social Studies, for example, indicates that teachers should provide instruction that complies with various thematic standards which include teaching about global connections and cultural diversity. To encourage young students to develop multiple perspectives, teachers need to pay attention not only to how they teach, but also to what they teach. Educators can guide students to develop cross-cultural understanding at an early age by using well-written picture book biographies which represent people from diverse backgrounds. This article explains what multiple perspectives are and offers resources and strategies for educators that will help young students develop an understanding of the frames of reference that different groups of people hold. It also emphasizes the importance of developing multiple viewpoints at a young age.     

Age- and Gender-Specific Reference Intervals for Fasting Blood Glucose and Lipid Levels in School Children Measured With Abbott Architect c8000 Chemistry Analyzer

Reference intervals for pubertal characteristics are influenced by genetic, geographic, dietary and socioeconomic factors. Therefore, the aim of this study was to establish age-specific reference intervals of glucose and lipid levels among local school children. This was cross-sectional study, conducted among Saudi school children. Fasting blood samples were collected from 2149 children, 1138 (53%) boys and 1011 (47%) girls, aged 6 to 18 years old. Samples were analyzed on the Architect c8000 Chemistry System (Abbott Diagnostics, USA) for glucose, cholesterol, triglycerides, HDL and LDL. Reference intervals were established by nonparametric methods between the 2.5th and 97.5th percentiles. Significant differences were observed between boys and girls for cholesterol and triglycerides levels in all age groups (P < 0.02). Only at age 6–7 years and at adolescents, HDL and LDL levels were found to be significant (P < 0.001). No significant differences were seen in glucose levels except at age 12 to 13 years. Saudi children have comparable serum cholesterol levels than their Western counterparts. This may reflect changing dietary habits and increasing affluence in Saudi Arabia. Increased lipid screening is anticipated, and these reference intervals will aid in the early assessment of cardiovascular and diabetes risk in Saudi pediatric populations.     

Functional observer based controller for stabilizing Takagi–Sugeno fuzzy systems with time-delays

This paper investigates the construction of a fuzzy functional observer for nonlinear systems with time-delays, and the application of the observer to estimate the state functions of the parallel distributed compensation controller for stabilizing the system. Two types of time-delays are considered: constant and time-varying delays with bounded time derivative. Stability conditions are obtained using Lyapunov–Krasovskii functional approach; and the conditions are transformed into linear matrix inequalities with equality constraints so that observer parameters can be calculated using the solution of these inequalities. Functional observer construction procedures are presented considering both constant and time-varying time-delays. Two examples, including one for obtaining a power system stabilizer for a single machine infinite bus system, are presented to illustrate effectiveness of the proposed design procedures.     

Interaction between prey and mutually interfering predator in prey reserve habitat: Pattern formation and the Turing–Hopf bifurcation

In this paper, we propose a diffusive prey-predator system with mutually interfering predator (Crowley–Martin functional response) and prey reserve. In particular, we develop and analyze both spatially homogeneous model based on ordinary differential equations and reaction-diffusion model. We mainly investigate the global existence and boundedness of positive solution, stability properties of homogeneous steady state, non-existence of non-constant positive steady state, conditions for Turing instability and Hopf bifurcation of the diffusive system analytically. Conventional stability properties of the non-spatial counterpart of the system are also studied. The analysis ensures that the prey reserve leaves stabilizing effect on the stability of temporal system. The prey reserve and diffusive parameters leave parallel impact on the stability of the spatio-temporal system. Furthermore, we illustrate the spatial patterns via numerical simulations, which show that the model dynamics exhibits diffusion controlled pattern formation by different interesting patterns.
