Correlates of household smoking bans in low-income families of children with and without asthma 总被引:1,自引:1,他引:0

Exposure to secondhand smoke (SHS) harms all children's health, especially children with asthma. Yet, children with asthma are as likely to live with smokers as healthy children. Household smoking bans are being advocated to reduce children's harm from SHS. To measure the effect of household smoking bans on child SHS exposure and to examine correlates of strict smoking bans in a low-income, diverse sample, 91 children with asthma were matched to 91 healthy children. All had at least one smoker living in their homes. Nicotine dosimeters, child cotinine assays, and maternal reports quantified child SHS exposures. Maternal reports of household smoking rules, behaviors, and beliefs, and other family characteristics were also gathered. The presence of a strict household smoking ban vastly reduced children's SHS exposures and was associated with fewer cigarettes smoked by the mother and by other family members, the belief that SHS was a personal health risk, having children with asthma, and living in a single-family home. Many children are exposed to high levels of SHS at home. Strict household smoking bans greatly decrease, but do not eliminate children's SHS exposure. Even in disadvantaged families, mutable factors were associated with strict smoking bans. Increased dissemination and use of established public health strategies are needed to reduce children's SHS exposures. 相似文献

The perception of social information is crucial for the survival of most animal species. Two recent studies demonstrate the joint contribution of innate mechanisms and perceptual experience to two aspects of social perception--faces and biological motion. Together, they highlight how important it is to consider faces and biological motion as different visual properties used by a broader social perception system. 相似文献

There is a paucity of selective, Tier 2 interventions that educators can implement for students with internalizing problems as part of their schools' Multi-Tiered Systems of Supports. To fill this void, the authors' purpose was to evaluate the efficacy, acceptability, and integrity of a structured school-based mentoring program, the Courage and Confidence Mentor Program (CCMP), for elementary students. A single-case experimental multiple baseline design across participants was used to evaluate the efficacy of the CCMP with 6 students. Visual analysis of the results and single-case effect size estimates revealed that all but 1 of the participants demonstrated noticeable reductions in internalizing problems as measured by teacher-completed direct behavior ratings. Findings were confirmed by other dependent variables gathered from students and teachers. Limitations of the methods and directions for future research involving Tier 2 interventions for elementary students with internalizing problems are discussed. 相似文献

Stimulus preference assessments often include items suspected to be highly preferred. If only high‐preference stimuli are assessed, preference hierarchies may not accurately predict the results of reinforcer assessments (RA). In this study, paired‐stimulus (PS) preference assessments using items suspected to be preferred (PS‐1) generated distinct preference hierarchies. Subsequent RAs (RA‐1) indicated that high‐preference and low‐preference stimuli were associated with similar response rates. Additional assessments (PS‐2) were then conducted, using the least‐preferred item from PS‐1 plus seven new stimuli. The least‐preferred items on PS‐1 ranked as most preferred on PS‐2, and on RA‐2, the top‐ranked items functioned as reinforcers, but low‐ranked items did not. Implications for incorporating low‐preference items into clinical/educational programming are discussed. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

Women of color are affected by both sexism and racism. We examined White women’s attitudes about sexism (hostile and benevolent sexism) and racial injustice (White empathic responses to racism) as correlates of their responses to a Black woman at risk for an alcohol-related sexual assault. White undergraduate women (N = 172) reported on their attitudes and then completed measures of blame and willingness to intervene in response to a scenario in which a woman named “LaToya” is at risk. All 3 types of attitudes were directly related to victim blame, whereas only hostile sexism was directly, negatively related to willingness to intervene. White empathic responses to racism moderated the associations between benevolent sexism and both victim blame and willingness to intervene. Results suggest that among White female bystanders, both hostile and benevolent sexist attitudes were related to increased blame and reduced willingness to intervene to help Black women at risk. The adverse effects of benevolent sexism, however, were reduced for those with greater concerns about racial injustice. 相似文献

Time perception in boys with attention-deficit/hyperactivity disorder according to time duration, distraction and mode of presentation. 总被引:2,自引:0,他引:2
In a recent theoretical model of attention-deficit/hyperactivity disorder (ADHD), Barkley (1997a) predicted that ADHD children experience impairments in their psychological sense of time. This was demonstrated in a series of experiments by Barkley, Koplowicz, Anderson, and McMurray (1997). The present study sought to investigate the effects of ADHD subtype, stimulus duration, mode of presentation (visual versus auditory) and distractors on the performance of a simple time reproduction task. Data were obtained from 44 ADHD children (14 predominantly inattentive and 30 combined type) and 44 age-matched Controls using the Time Perception Application version 1.0 (Barkley, University of Massachusetts Medical Center, 1998). Results revealed that the ADHD children made significantly larger errors on Visual time reproduction tasks than the Controls, regardless of ADHD subtype or the presence of distractors. Furthermore, ADHD children were more likely to overestimate the shorter time intervals (0.5 and 2 s) and underestimate the longer time intervals (3, 4 and 6 s) relative to Controls. No group differences were observed on the auditory time reproduction task, with both ADHD and Control groups consistently underestimating the durations to be reproduced. The results of this study provide further support for the prediction that children with ADHD have an impaired sense of time. 相似文献

Although the neuropathology of Korsakoff's syndrome (KS) was first described well over a century ago and the characteristic brain pathology does not pose a diagnostic challenge to pathologists, there is still controversy over the neuroanatomical substrate of the distinctive memory impairment in these patients. Cohort studies of KS suggest a central role for the mammillary bodies and mediodorsal thalamus, and quantitative studies suggest additional damage to the anterior thalamus is required. Rare cases of KS caused by pathologies other than those of nutritional origin provide support for the role of the anterior thalamus and mammillary bodies. Taken together the evidence to date shows that damage to the thalamus and hypothalamus is required, in particular the anterior thalamic nucleus and the medial mammillary nucleus of the hypothalamus. As these nuclei form part of wider memory circuits, damage to the inter-connecting white matter tracts can also result in a similar deficit as direct damage to the nuclei. Although these nuclei and their connections appear to be the primary site of damage, input from other brain regions within the circuits, such as the frontal cortex and hippocampus, or more distant regions, including the cerebellum and amygdala, may have a modulatory role on memory function. Further studies to confirm the precise site(s) and extend of brain damage necessary for the memory impairment of KS are required. 相似文献
