Over 200,000 American children visit the emergency room annually after a playground injury. Among the most promising means to reduce playground injuries is through increased quantity and quality of playground supervision by adults. To implement empirically supported playground supervision interventions, it is essential to understand how supervision prevents injuries. Recent research suggests supervision likely prevents injuries through several different mechanisms; this paper discusses six: (a) Supervisors repetitively teach children playground rules; (b) supervisors recognize and stop children's dangerous behavior; (c) supervisors prevent children from behaving impulsively; (d) the presence of a supervisor causes children to behave differently; (e) supervisors change children's attribution of risk; and (f) supervisors have influence as modelers and persuaders of safe behavior. Theoretical implications for future work and applied implications for the development of playground safety interventions are discussed. 相似文献

影响大学生人际关系主观因素的初步研究 总被引:13,自引:0,他引:13
用自编的大学生人际关系主观因素问卷对800名1-4年级本科生进行调查。结果表明,影响大学生人际关系的主观因素涉及人际安全、人际疑虑、人际张力和人际报复;大学生的人际安全因子得分为3.86,人际张力、人际疑虑和人际报复因子得分和总均分在1.8-2.6之间;人际张力、人际疑虑、人际报复因子存在显著的年级差异(p<0.01);男生在人际报复因子上的得分明显高于女生;理科生的人际张力、人际报复和主观因素总均分显著高于文科生,人际安全因子得分显著低于文科生。表明大学生的人际安全感较强,人际交往和相处中的负性体验较弱,但存在年级、性别、专业等方面的差异。 相似文献

药物的安全性是药物评价的首要标准。《欧盟传统药品法案》对中药的技术壁垒和我国对某些中药的毒副作用的披露,使得中药的安全性问题日益突出,使得中药产业面临前所未有的危机。对中药安全性的理性认识是扩大其国内市场占有率、走向国际市场所必须突破的瓶颈,也是中药产业危机管理的必由通道。这是一场深刻的文化革命。 相似文献

Seat belt use is an important factor in the prevention of automobile accidents involving injuries and fatalities. The current study used a multielement design to compare the “Click It or Ticket” and “Please Buckle Up—I Care” procedures. Results indicate that the Click It or Ticket prompt resulted in a 20‐percentage‐point increase in seat belt use, and Please Buckle Up—I Care resulted in a 14‐percentage‐point increase. 相似文献

This study evaluated video scoring and feedback about scoring as a safety intervention among 6 nursing staff. The dependent variable was safety behavior on one‐person transfers. Following baseline, 5 nursing staff participated in an information phase. A video scoring phase was then introduced for all 6. A feedback phase was added for 2 participants. All participants experienced treatment withdrawal. Information resulted in improvements for all 5 participants who received it. Further improvements were observed during video scoring for the 5 participants who improved following information. No improvements were observed for the participant who received only video scoring. Safety feedback further improved safety for the 2 participants who received it. However, participants' behavior returned to video scoring levels during withdrawal. 相似文献

Communally organized, as opposed to bureaucratically organized, schools are expected to provide significant advantages to
students in terms of their cognitive and social growth. However, for students to avail themselves of these benefits, they
need to experience school as a community. One factor that may influence whether students view their school as a functional
community is the kind of teacher–student and peer interactions they observe or personally experience. This study examines
the effects of positive and negative interracial interactions on whether students sense that their school is a community.
Analysis of a large sample of elementary and secondary schools in a major urban school district show that positive interracial
interactions contribute to students’ sense of school community while negative actions inhibit that sense.

Stimuli inevitably generated by behavior that avoids electric shock are inherently reinforcing. 下载免费PDF全文

A molecular analysis based on the termination of stimuli that are positively correlated with shock and the production of stimuli that are negatively correlated with shock provides a parsimonious count for both traditional discrete-trial avoidance behavior and the data derived from more recent free-operant procedures. The necessary stimuli are provided by the intrinsic feedback generated by the subject's behavior, in addition to those presented by the experimenter. Moreover, all data compatible with the molar principle of shock-frequency reduction as reinforcement are also compatible with a delay-of-shock gradient, but some data compatible with the delay gradient are not compatible with frequency reduction. The delay gradient corresponds to functions relating magnitude of behavioral effect to the time between conditional and unconditional stimuli, the time between conditioned and primary reinforcers, and the time between responses and positive reinforcers. 相似文献

The relation between heart-rate deceleration and the expression of positive affect in infancy is examined by testing the hypothesis that intensity of orienting (as indexed by heart-rate deceleration) is predictive of intensity of positive affect (smile size and duration). A social-stimulation procedure was utilized to elicit smiles in 41 3-month-old infants. The first smile elicited was coded for smile size and duration, and the preceding heart-rate deceleration was coded for magnitude, duration, and slope of deceleration. Slope and duration of heart-rate deceleration proved to be reliable predictors of smile size, but none of the heart-rate measures correlated with smile duration. Results suggest that the steeper and more rapid the deceleration, the larger the ensuing smile. Possible mechanisms for this finding are discussed. 相似文献

Many deaths from cardiopulmonary arrest can be prevented by the prompt and effective administration of cardiopulmonary resuscitation (CPR). In this study, we examined the standard training program for teaching CPR to emergency medical technicians (EMTs). We developed an alternative experimental program whereby the behaviors involved in CPR were assessed easily and in greater detail. This assessment provided the basis for a system in which effective CPR skills were reinforced and problems were corrected. Subjects who were trained in CPR according to this experimental program performed more effectively than subjects in the standard program. In addition, retention (maintenance) measures indicated that experimental subjects continued to perform well, often more effectively than professionally employed EMTs. 相似文献
