The presence of a best friend buffers the effects of negative experiences.

Abstract: The goal of the current study was to examine how the presence of a best friend might serve as protection against the effect of negative experiences on global self-worth and the hypothalamic-pituitary-adrenocortical axis (HPA axis). A total of 103 English-speaking male (n = 55) and female (n = 48) participants from Grade 5 (M = 10.27 years) and Grade 6 (M = 11.30 years) completed booklets about their experiences that occurred 20 min previously and how they felt about themselves at the moment, and they provided saliva multiple times per day over the course of 4 consecutive days. Having a best friend present during an experience significantly buffered the effect of the negativity of the experience on cortisol and global self-worth. When a best friend was not present, there was a significant increase in cortisol and a significant decrease in global self-worth as the negativity of the experience increased. When a best friend was present, there was less change in cortisol and global self-worth due to the negativity of the experience.

Resource-aware secure ECG healthcare monitoring through body sensor networks

Abstract: Real-time medical data about patients' physiological status can be collected simply by using wearable medical sensors based on a body sensor network. However, we lack an efficient, reliable, and secure BSN platform that can meet increasing needs in e-healthcare applications. Many such applications require a BSN to support multiple data rates with reliable and energyefficient data transmission. In this article we propose a secure and resource-aware BSN architecture to enable real-time healthcare monitoring, especially for secure wireless electrocardiogram data streaming and monitoring. A cross-layer framework was developed based on unequal resource allocation to support efficient biomedical data monitoring. In this framework important information (e.g., critical ECG data) is identified, and extra resources are allocated to protect it. Furthermore, BSN resource factors are exploited to guarantee a strict requirement of real-time performance. In this work we integrate biomedical information processing and transmission in a unified platform, where secure data transmission in a BSN proceeds with energy efficiency and minimum delay. In particular, we present a wearable ECG device consisting of small and low-power healthnode sensors for wireless three-lead ECG monitoring. Experimental and simulation results demonstrate that the proposed framework can support real-time wireless biomedical monitoring applications.

“I Believe in Inclusion, But…”: Regular Education Early Childhood Teachers' Perceptions of Successful Inclusion

Abstract: The purpose of this qualitative study was to describe regular education early childhood teachers' perceptions of those factors that contributed to or hindered their success in inclusive classrooms. From among the K-3 teachers in one pro-inclusion school district, six teachers (three self-described as successful with inclusion and three as unsuccessful) were randomly selected to participate in a series of four semi-structured interviews about their current experiences with inclusion. Analysis of the interview data indicated a strong shared belief in the fundamental value of inclusion, as well as revealing four themes that affected their perceptions about inclusion. The themes indicated a need for: more adequate and focused training (for both regular and special education personnel), better consideration of classroom load factors (including class size, ratios, and type and severity of special needs), more reliable support (in-class, collaborative, and administrative), and help to find more time to ...

The effect of offender and victim characteristics on sexual assault case processing decisions

Abstract: Previous research testing the sexual stratification hypothesis has demonstrated that the defendant's race interacts with the victim's race to produce harsher sentences for blacks who sexually assault whites. Research also has demonstrated that victim characteristics affect outcomes of sexual assault cases. We use data on defendants bound over for trial in Detroit Recorder's Court to build on and extend this research. We examine the effect of the racial makeup of the offender/victim pair on a series of sexual assault case outcomes, and we test for interaction between offender/victim race, the relationship between the victim and the offender, and evidence of risk-taking behavior by the victim. Our results show that sexual assaults involving black men and white women are not always treated more harshly than other types of assaults. We conclude that the sexual stratification hypothesis must be modified to account for the role of factors other than the racial composition of the offender/victim pair.

Elements of death anxiety and meanings of death

Abstract: The objectives of this study were: (1) to test hypotheses that women would have higher death anxiety than men and that older persons would have lower death anxiety than younger people; and (2) to probe for meanings of death among a large, heterogeneous sample. A group of 599 adolescents and adults completed a death anxiety scale; factor analysis of the resultant data revealed seven orthogonal factors. Both hypotheses were supported at acceptable levels of significance. Item analysis revealed additional information on meanings of death: Older respondents indicated a concern over the existence of an afterlife and over loss of personal control; women expressed more fear of pain and bodily decomposition. The strongest finding was variation in death anxiety by age, which confirms Butler's contention that the life review helps the aged to resolve conflicts and relieve anxiety.
