Objective
To explore whether adults possess implicit attitudes toward children and whether those attitudes are especially negative among respondents who are high in child physical abuse (CPA) risk.Methods
The present study used an implicit evaluative priming procedure. In this procedure, participants were instructed to make decisions about the evaluative implications of target words. These words were preceded by photographs of child faces or adult faces displaying positive, neutral, or negative expressions. Reaction times for the evaluative decisions were used as an index of the extent to which photos invoked negative or positive evaluative reactions.Results
Results from 2 studies, the first conducted on a student sample (N = 90) and the second on a parent sample (N = 95), demonstrated that evaluative congruence between the facial expressions displayed in photographs and the target words facilitated responses. Furthermore, the results suggested that regardless of CPA risk, child faces, relative to adult faces, facilitated responses to negative target words, suggesting an out-group bias. This implicit out-group bias was not moderated by respondents’ CPA risk status.Conclusions
Faces of children, relative to faces of adults, appear to activate negative information structures that facilitate evaluative decisions of negative stimuli, suggesting an out-group bias. Given that out-group biases typically lead to less favorable treatment of out-group members, additional research is needed to examine the pervasiveness of negative evaluative biases towards children and the potential implications of such biases on children's lives. Further, research examining whether high CPA risk parents and low CPA risk parents differ in how they manage initial negative evaluative reactions is needed. 相似文献3.
目的:探讨肺炎衣原体(TWAR)与急性心梗(AMI)、心绞痛(Angina)型冠心病之间的关系。方法:采用多聚合酶链反应(PCR)技术对200例冠心病(急性心梗56例,不稳定心绞痛124例,稳定心绞痛20例)和180例非冠心病患者进行全血标本肺炎衣原体DNA检测。结果:急性心梗组肺炎衣原体DNA阳性率为73.2%,不稳定心绞痛组为52.4%,稳定心绞痛组为45.0%;对照组为21.1%,三组与对照组相比,差异均有显著性(P〈0.01,P〈0.01,P〈0.05)。结论:肺炎衣原体感染与急性心梗、心绞痛型冠心病存在密切关系。 相似文献

目的探讨丙泊酚联合芬太尼深度静脉麻醉胃镜检查术后患者不适的影响因素。方法随机抽取2010年9月-2010年10月某院深度镇静麻醉胃镜检查术受检者270名,术前采用自制问卷调查,记录受检者术中术后多项指标,分析深度镇静麻醉胃镜检查术术后患者不适的主要影响因素。采用描述性统计分析、χ2检验、单因素非条件logistic回归分析。结果术后不适的影响因素有年龄、BMI、是否患有冠心病、是否曾经做过胃镜检查、术前心理是否紧张、术中是否出现呛咳和躁动、麻醉药物起效时间、术后清醒时间。结论对于年龄较大、肥胖、患有冠心病、以往从未做过胃镜检查、术前紧张、术中出现呛咳躁动、麻醉药物起效时间长的受检者应在术中密切观察其呼吸、循环受抑制情况,并在术后延长观察时间。 相似文献

This article deals with kinematic and kinetic conditions in volleyball attack and identifies loads in the shoulder joint. Joint angles and velocities of individual segments of upper limb were measured with the use of the motion capture system XSENS. Muscle forces and loads in skeletal system were calculated by means of mathematical model elaborated in AnyBody system. Spikes performed by players in the best and worst way were compared with each other. The relationships were found between reactions in shoulder joint and flexion/extension, abduction/adduction and rotation angles in the same joint and flexion/extension in the elbow joint. Reactions in shoulder joint varied from 591 N to 2001 N (in relation to body weight [BW] 83–328%).
The analysis proved that hand velocity at the moment of the ball hit (which varied between 6.8 and 13.3 m s–1) influences on the value of reaction in joints, but positions of individual segments relative to each other are also crucial. It was also proved in objective way, that position of the upper limb during spike can be more or less harmful assuming that bigger reaction increases possibility of injury, what can be an indication for trainers and physiotherapists how to improve injury prevention. 相似文献

The aim of this study is to propose an automatic and real-time social media analytics framework with interactive data visualizations to support effective exploration of knowledge about adverse drug reaction (ADR) surveillance. This proposed framework has been prototypically implemented on the basis of social media data. A longitudinal diabetes patient online community data (AskaPatient.com) as well as FDA Adverse Event Reporting Systems (FAERS) data as a benchmark were used to evaluate our proposed approach’s performance. Based on the results, our approach significantly increases the precision and accuracy for ADR extraction. The number of ADR cases, the time when the ADRs occurred, and the rating of Glucophage have been visualized that resulted by mining a collection of 870 ADRs posted in Askapatents.com over a certain time period (from 2001 to 2015). The results have important implications for pharmaceutical companies and hospitals wishing to monitor ADRs of medicines. 相似文献

Three hundred forty-two anonymous surveys regarding unwanted sexual experiences (USE) were filled out in three clinic sites: a pediatric sexual abuse clinic, family practice clinic, and family planning clinic. In the latter two clinics, 40% of females and 16% of males had at least one unwanted sexual experience prior to turning 18 years old. Only 91% of the sexual abuse clinic patients indicated their experience was unwanted. In addition, 27% of the subjects had wanted sexual experiences that were illegal and underreported: These experiences involved a partner at least 4 years older or younger. While feelings of victimization were most common, self-blame and naivete about the abuse were also frequently reported, especially in those who had an USE with a peer. Ambivalence, self-blame, and peer pressure were associated with a lower tendency to disclose one's USE. Although unwanted and illegal sexual experiences were less common in Hispanic females, feelings of self-blame and ambivalence regarding their USE were more frequent in comparison with White females. These findings have important investigative and therapeutic implications for professionals who encounter victims of sexual abuse. 相似文献
