We attempted to isolate the evocative effects of the establishing operation for positively reinforced problem behavior with 2 participants. The study consisted of three phases. First, a functional analysis identified tangible items (Participant 1) and attention (Participant 2) as maintaining problem behavior. Second, access to tangible items and attention was systematically controlled (continuous access vs. no access) immediately prior to functional analysis sessions in which these consequences were delivered contingent on problem behavior. Results of this phase indicated that problem behavior occurred at higher levels when access to tangible items and attention was restricted. In the third phase, prior access was again controlled, but problem behavior produced no consequences. Results of this final phase indicated that problem behavior occurred at higher levels during extinction sessions when participants did not have prior access to the reinforcers. 相似文献

Mapping the Social World of Classrooms: A Multi‐Level,Multi‐Reporter Approach to Social Processes and Behavioral Engagement 下载免费PDF全文
Understanding the social context of classrooms has been a central goal of research focused on the promotion of academic development. Building on the current literature on classroom social settings and guided by a risk and protection framework, this study examines the unique and combined contribution of individual relationships and quality of classroom interactions on behavioral engagement among low‐income Latino students in kindergarten to fifth grade (N = 111). Findings indicate that individual relationships with teachers and peers and classroom quality, each independently predicted behavioral engagement. Moreover, high‐quality classrooms buffered the negative influence of students’ difficulties in individual relationships on behavioral engagement. Findings illuminate the need to consider multiple layers of social classroom relationships and interactions and suggest the potential benefit of targeting classroom quality as a mechanism for improving behavioral engagement in urban elementary schools. 相似文献

African American youth, especially those who live in low-income communities, are at increased risk for experiencing higher juvenile justice involvement, poorer mental health, low school engagement, higher illicit drug use, and STIs, relative to their higher income peers and those from other ethnic backgrounds. However, few studies have examined the relationship between family stressors and these multiple youth concerns. This study examines the relationship between family stress (i.e., having an adult in the home with a history of mental illness, substance use, and incarceration) and youth concerns such as substance use, mental health challenges, low school engagement, juvenile justice involvement, and STI risk behaviors. A total of 638 African American adolescents living in predominantly low-income, urban communities participated in the study by completing self-report measures on the above constructs. Logistic regressions controlling for age, gender, socioeconomic status, and sexual orientation indicated that adolescents who reported higher rates of family stress were significantly more likely to report mental health problems, delinquent behaviors, juvenile justice involvement, drug use, risky sex, and lower school engagement factors. Findings suggest that attending to the developmental concerns of youth also requires addressing the needs of the family unit. 相似文献

This paper focuses on compost use in overpasses and underpasses for wild animals over roads and other similar linear structures. In this context, good quality of compost may result in faster and more resistant vegetation cover during the year. Inter alia, this can be interpreted also as reduction of damage and saving lives. There are millions of tones of plant residue produced every day worldwide. These represent prospective business for manufacturers of compost additives called “accelerators”. The opinions of the sale representatives’ with regards to other alternatives of biowaste utilization and their own products were reviewed. The robust analyzes of several “accelerated” composts revealed that the quality was generally low. Only two accelerated composts were somewhat similar in quality to the blank sample that was produced according to the traditional procedure. Overlaps between the interests of decision makers on future soil fertility were weighed against the preferences on short-term profit. Possible causes that allowed the boom of these underperforming products and the possible consequences are also discussed. Conclusions regarding the ethical concerns on how to run businesses with products whose profitability depends on weaknesses in the legal system and customer unawareness are to follow. 相似文献

GaN photonic crystal slabs on InGaN/GaN multi-quantum well light-emitting diodes have been formed by dry etching using nanoporous anodic alumina templates, which have a periodic lattice constant of 105 nm and a hole diameter of 45 nm. The photonic crystal slab shows an enhanced intensity of photoluminescence due to the nanohole pattern array producing Fabry–Perot like interference. A rough surface of nanoholes results in a broad spectrum with a small oscillation, and well-ordered multiple facets of nanoholes results in a relatively sharp spectrum with a large oscillation. 相似文献

Nine-year-old Korean children (N = 299) were tested for reaction time (RT) and intelligence measured by Raven's Standard Progressive Matrices. Reaction times were broken into decision times and movement times and into three degrees of complexity. The results showed low but generally statistically significant correlations between decision times and intelligence. Generally, no significant differences existed between movement times and intelligence. Boys showed significantly faster movement times than girls did. 相似文献
