Examining the effects of news coverage linking undocumented immigrants with criminality: Policy and punitive implications

Although research suggests that there is no meaningful real-world connection between crime rates and undocumented immigrants, media coverage of this group almost exclusively portrays them as criminals. The present two-study investigation experimentally tests the effects of exposure to crime news depicting undocumented immigrant suspects on White viewers’ social judgments. To this end, assumptions from social identity theory were applied to research and theorizing on mediated intergroup threat and compound penalties for immigrant criminality. Results from Study 1 and Study 2 indicate that when White viewers are exposed to threatening crime news featuring undocumented immigrants, out-group bias emerges in the form of harsher sentencing. In Study 1, when exposed to highly threatening coverage, attitudes toward immigration and in-group identification partially mediated and moderated this relationship, respectively.     

谈造型基础训练中的悟理观

长期以来,国内高校的造型基础教学多局限于对学生造型基本功的培养,把造型基础课程仅仅看成了提高学生造型能力的一种手段,忽视了民族绘画精神的体现。在中国传统绘画的学习和创作中,对于"悟性"的探讨,有着悠久的历史,如果在造型基础学习中能够加以关注,显然有利于中国美术的纵深发展。     

冤假错案的成因及对策

审视近年来不断披露的冤假错案,不难发现任何一起冤假错案的形成都不是偶然的,而是各种因素合力作用的结果,尤其是应当对冤假错案的发生起着重要防范作用的审判环节,却因未能将程序公正的价值根植于法官内心,导致疑罪从无、非法证据排除、审判依法独立等原则在具体的审判实践中无法实现,是一批冤假错案发生的主要根源。需要坚持疑罪从无、非法证据排除、依法独立行使审判权三大原则,以求将冤假错案的发生率控制在最低的限度内。     

“青少年犯罪”概念之解析

"青少年犯罪"这一概念在犯罪学中占有极为重要之地位,其抓住了青少年群体的特殊性,具有合理性与独有优势,而解析此概念是研究青少年犯罪现象的重要前提,具体而言,"青少年犯罪"中青少年的范围应在十四岁到二十五岁之间,犯罪一概念应当做广义理解,同时包括违法行为和严重违反道德的具有社会危害性的行为,刑法中明确规定的罪行只是其典型形态。     

淮南市3~6岁幼儿各项身体形态分析

为全面了解淮南市幼儿的形态指标、身体素质现状,2010年淮南师范学院与淮南市体育局共同组织了对淮南市幼儿的调查与测试,把测得数据采用《国民体质测定标准手册》中幼儿部分的评定方法与标准进行统计处理。结果表明：淮南市3~6岁幼儿身体形态发育随着年龄的增加,他们的身高与体重值均增加,呈逐年升高趋向;男性幼儿和女性幼儿的身体形态从3岁就呈现出差异,这主要是由遗传决定的,这种差异在7岁以后,伴随着年龄的增长表现更为明显。     

基于内容的图像检索系统比较和分析

指出基于内容图像检索的优势;比较分析了多代理平台、CIRES、Chabot和SIMPLicity4个典型的基于内容图像检索系统,总结了它们的结构、功能、主要贡献及应用领域等,并针对语义鸿沟、检索特征单一、相互之间难以互访3个方面的问题．提出了应对措施。     

论未成年人强制性教育措施——兼论与社区矫正之契合

未成年人强制性教育措施具有灵活、开放和有效的特性,在预防犯罪、维护社会稳定方面发挥着重要作用,但却存在一定程度的滥用。未成年人社区矫正的推行更是加剧了其适用方式的错位与失衡。引入社区矫正,推动未成年人强制性教育措施的去行政化、社会化和多样化。通过两者的衔接与契合,实现对该措施的改造。     

运动干预对小学生体形态和体成分影响的实验研究

分析以运动为主的干预方式对小学生体形态和体成分的干预情况,并探讨适合小学生防控肥胖的有效手段。方法：随机抽取四所小学4、5年级中9-13岁超重/肥胖学生作为实验干预对象,共计430人,分为有氧组、无氧组、综合组和对照组,实验持续16周,每周运动5天,每天约65min;运动强度控制在靶心率范围内。结果：经过16周运动干预后,小学生的腰围、臀围和体脂百分比均显著下降(p<0.05),体重级别与干预方式在上述三个指标上均无交互作用存在(p>0.05),干预方式显著影响腰围、臀围和脂肪百分比(p<0.05),结论：16周以学校为基础的运动干预方式能够明显减小小学生的腰围、臀围等体形态指标,对体重的影响效果不明显;有氧为主的运动对体形态的改善效果最优;运动干预方式能够显著降低小学生的体脂百分比,有效改善体成分;有氧为主的运动效果最优。

Effect of chainring ovality on joint power during cycling at different workloads and cadences

Non-circular chainrings theoretically enhance cycling performance by increasing effective chainring diameter and varying crank velocity, but research has failed to consistently reproduce the benefits in cycling trials. The aim of this study was (1) to investigate the effect of different chainring shapes on sagittal knee joint moment and sagittal lower limb joint powers and (2) to investigate whether alterations are affected by cadence and workload. Fourteen elite cyclists cycled in six conditions (70, 90 and 110 rpm, each at 180 and 300 W), for 2 min each, using three chainrings of different ovalities (1.0–1.215). Kinematic data and pedal forces were collected. For most conditions, only the chainring with the highest ovality (1.215) was characterised by smaller sagittal knee joint moments, smaller relative sagittal knee joint power contribution and larger relative sagittal hip joint power contribution, which suggests a change from maximising efficiency to maximising power production. Effect sizes increased with higher cadences, but not with higher workload. This study has application for athletes, clinicians and sports equipment industry as a non-circular chainring can change joint-specific power generation and decrease knee joint moment, but certain ovality seems to be necessary to provoke this effect.
