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 (= 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

A number of recent studies have documented rapid changes in behavioural sensory acuity induced by aversive learning in the olfactory and auditory modalities. The effect of aversive learning on the discrimination of low-level features in the visual system of humans remains unclear. Here, we used a psychophysical staircase procedure to estimate discrimination thresholds for oriented grating stimuli, before and after differential aversive learning. We discovered that when a target grating orientation was conditioned with an aversive loud noise, it subsequently led to an improvement of discrimination acuity in nearly all subjects. However, no such change was observed in a control group conditioned to an orientation shifted by ±90° from the target. Our findings cannot be explained by contextual learning or sensitisation factors. The results converge with those reported in the olfactory modality and provide further evidence that early sensory systems can be rapidly modified by recently experienced reinforcement histories.  相似文献

The delivery of food contingent on 10 s of consecutive toy engagement resulted in a decrease in engagement and a corresponding increase in other responses that had been previously reinforced with food. Similar effects were not observed when tokens exchangeable for the same food were delivered, suggesting that engagement was disrupted by the contingent provision of the food, which may have functioned as a discriminative stimulus that occasioned competing responses.  相似文献

The majority of research on self‐monitoring has focused on the positive aspects of this personality trait. The goal of the present research was to shed some light on the potential negative side of self‐monitoring and resulting consequences in two independent studies. Study 1 demonstrated that, in addition to being higher on Extraversion, high self‐monitors are also more likely to be low on Honesty‐Humility, which is characterized by a tendency to be dishonest and driven by self‐gain. Study 2 was designed to investigate the consequences of this dishonest side of self‐monitoring using two previously unexamined outcomes: moral disengagement and unethical business decision making. Results showed that high self‐monitors are more likely to engage in unethical business decision making and that this relationship is mediated by the propensity to engage in moral disengagement. In addition, these negative effects of self‐monitoring were found to be due to its low Honesty‐Humility aspect, rather than its high Extraversion side. Further investigation showed similar effects for the Other‐Directedness and Acting (but not Extraversion) self‐monitoring subscales. These findings provide valuable insight into previously unexamined negative consequences of self‐monitoring and suggest important directions for future research on self‐monitoring.

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

This study examined how psychotherapists address hypothetical nonsexual multiple relationships dilemmas with Asian American clients and identified predictors of conservative decisions and the use of culture-based rationales. This survey of 787 Asian American and non-Asian American psychotherapists revealed that clinicians rely on mostly their personal policies and seldom focus on the clients' cultural backgrounds. Psychotherapists who consider their clients' Asian culture have more cultural knowledge and awareness, have been mental health providers longer, and are Asian American and female. Clinicians who avoid multiple relationships tend to cite formal policies as justification and are less likely to consider clients' cultural worldviews, the therapeutic relationship, or their own values. The results are discussed in terms of specific revisions needed in the American Psychological Association Ethics Code, the benefits of more frequent consultation with colleagues and supervisors about ethical dilemmas, and recommendations for psychotherapists.  相似文献
