School shootings are a concern due to their impact in the local community. This paper aimed to (a) establish frequent characteristics of the offender and offence, (b) explore the differences between offenders who are over the age of 18 years and those who are younger, and (c) consider the underlying themes of the offence characteristics. Data were collected on 28 cases through accessing resources such as West Law and case studies. The majority of the offenders were Caucasian and US citizens and suffered from depression. Their offences were primarily well planned, involved more than three deaths, and resulted in the offender committing suicide. Pearson's chi‐square test and Fisher's exact test identified significant differences between the two age groups. Offenders who were 18 years of age or under were more likely to experience depression, be US citizens and be linked to the school. Additionally, offenders who were 18 years of age or under were more likely to have stolen their weapons and made threats prior to the incident. Smallest space analysis revealed four thematic regions in relation to the offence characteristics: making an impact, delivering a message, doing unrestrained activity, and targeting specific individuals. These findings have implications for risk assessment and furthering understanding. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

Differential bundle functioning (DBF) analyses were conducted to determine whether seventh and eighth grade second language learners (SLLs) had lower probabilities of answering bundles of math word problems correctly that had heavy language demands, when compared to non-SLLs of equal math proficiency. Math word problems on each of four test forms (two at Grade 7 and two at Grade 8) were bundled together if they used the passive voice, conditional clause, relative clause, or a combination of any two. The results showed that the average total scores for SLLs was significantly lower than that for non-SLLs on each test form. However, only two bundles (passive voice and conditional clause at Grade 7 on Form 2) indicated statistically significant DBF against SLLs in favor of matched non-SLLs. An additional step was taken to determine whether the two bundles that showed statistically significant DBF against SLLs had biased the mean total scores for this group.The Walker, Zhang, Banks, and Cappaert (2012) procedure established for this purpose showed that this was not the case. Implications of the results are provided as well as suggestions for future research. 相似文献

对传统的假设检验作为心理学实验的数据分析工具的评价涉及两个标准:首先是它是否合法,其次是它是否有用。置于频率学派统计学框架中的传统假设检验在逻辑上实际上是合法的;但它在效用性方面则有着备择假设不可证伪以及只能提供定性结论这两方面的缺陷。置信区间能够集中地改进和弥补这些缺陷。对传统假设检验使用中错误的澄清也使得研究者们开始重视PSI问题,这使得心理学实验的设计和数据分析从关注总体转向关注个体。 相似文献

This study examines the mediating role of effortful control between reactive temperament traits (negative affectivity and extraversion) and children’s internalizing and externalizing behavioural problems. The sample was composed of 424 non-clinical children from 3 to 6 years of age (60% male). Use of a structural equation model revealed effortful control-mediated relations between reactive temperament traits and behavioural problems. Nevertheless, uniquely and directly, negative affect predicted externalizing problems and extraversion predicted internalizing problems. Assessment of invariance by children’s sex showed that the mediating role of effortful control tends to be stronger for externalizing problems in boys than in girls. Results showed no significant age differences. According to these results, effortful control as a method of self-regulation seems to be an essential process through which reactive temperament traits affect a child’s psychological adjustment. 相似文献

Relationships Among Paternal Involvement and Young Children's Perceived Self-Competence and Behavioral Problems 总被引:1,自引:0,他引:1

We examined the relationships of father involvement to young children's perceived self-competence and fathers' and mothers' perceptions of their children's internalizing and externalizing behavioral problems. The results indicated that mothers in families in which father involvement is high may have a more positive outlook regarding their child's behavior than do mothers in families in which father involvement is low. Fathers who were highly involved indicated their children have more behavior problems than fathers who were not highly involved. High father involvement was associated with increased children's feelings of paternal acceptance, a factor that plays a role in the development of self-concept and esteem. 相似文献

汉代象数学家的人文情怀 总被引:1,自引:0,他引:1
汉代象数学家历来被认为是只参天象不释人事,本文以孟京学派和《易纬》为例,通过对其象数学的深层分析,认为孟京讲卦气、讲天象,目的正是为了察人事、定人伦以明王道;《易纬》更显示了教化人民的道德意识和治国安邦的政治理念。前者以经学形式、后者以神学形式表达了各自强烈的人文情怀。 相似文献

中学欺侮行为现状研究 总被引:10,自引:0,他引:10
对湖南两所中学的399名中学生学校欺侮行为进行了研究,结果发现,经常受欺侮者为27%,欺侮者为14%。欺侮行为发生的地点是学校,发生的时间一般是课间。对于受欺侮者而言,没有性别差异,但是欺侮者以男生为主。受欺侮行为随年龄的增长在下降,而欺侮行为为则在上升。 相似文献

初中生函数概念发展的特点 总被引:2,自引:0,他引:2
本研究通过测验法对北京市六所中学的802名初一至初三的学生进行考察,研究了初中生函数要领的发展水平及其特点,结果表明,初中三个年级学生函数要领的发展,从总体上看,随着看级的增高呈上升的发展趋势,但年级结学生函数概念发展的影响不显著,制约 初中学生函数的概念发展水平的关键是,学生所受教育的质量,学生主要以接受教育的方式来获得函数概念。 相似文献
