Latchkey children and susceptibility to peer pressure: An ecological analysis.

Data on adolescents' after-school experiences and their susceptibility to peer pressure were derived from surveys administered to a heterogeneous sample of 865 adolescents in Grades 5–9. Consistent with the findings of previous studies, the results show that Ss who reported home after school were not significantly different from those who were supervised by their parents at home during after-school hours. However, when a 2nd sample of latchkey children (n?=?594) was studied to include greater variation in after-school experiences, Ss who were more removed from adult supervision were found to be more susceptible to peer pressure to engage in antisocial activity. Ss who were home alone were less susceptible to peer pressure than are those who were at a friend's house after school, and those who were at a friend's house, in turn, were less susceptible than were those who describe themselves as "hanging out." Moreover, latchkey Ss whose parents knew their whereabouts and those who had been raised authoritatively were less susceptible to peer influence than were their peers, even if their afternoons were spent in contexts in which adult supervision was lax and susceptibility to peer pressure was generally high.

砖混结构房屋施工中容易发生的问题及解决对策

砖混结构是指小部分钢筋混凝土及大部分砖墙承重的结构。在砖混结构中加入构造柱和圈梁,能提高结构的抗震能力,但由于一些施工管理人员对构造柱的作用原理认识不清,施工中出现很多质量问题,使有些部位的构造柱和圈梁不但达不到抗震目的,反而影响了结构安全性。     

宝钢3号高炉出铁场设计

宝钢３号高炉出铁场为矩形双面出铁场布置，与１、２号高炉相比，渣沟较短，两铁口间的夹角加大，出铁场更为平坦，炉前机械化程度高。采用固定主沟，渣铁沟设有侧温热电偶，以监测其内衬的温度变化。

夹芯板力学分析及优化

以总重量最轻为目标函数,以强度和刚度作为约束条件,对冲孔夹芯板进行分析,采用Optistruct求解器,依据分析的结果,对夹芯板进行优化设计,既降低了制造成本同时也减小了夹芯板传给主体结构的荷载。     

隧道爆破振动对上方居民楼震害分析

为了保证房屋安全,对地表和居民楼进行了监测,以便及时调整爆破参数。结合房屋的破坏特点与监测数据进行了分析,研究表明:隧道爆破引起地表和房屋的振动速度和频率存在差异,随着高度变化房屋振动随之减小。对爆破振动的衰减规律和房屋的响应特征进行了总结分析,得出破坏的原因是:微差爆破时间过短,波形有重叠放大现象;自振频率和爆破频率接近,有共振现象;空洞效应放大了振速;房屋年代久远。最后提出了减振的对策,对爆破有较好的控制。
