Sexual abuse,residential schooling and probable pathological gambling among Indigenous Peoples     

《Child abuse & neglect》2015

Sexual abuse leads to short-term and long-lasting pervasive outcomes, including addictions. Among Indigenous Peoples, sexual abuse experienced in the context of residential schooling may have led to unresolved grief that is contributing to social problems, such as pathological (disordered) gambling. The aim of this study is to investigate the link between child sexual abuse, residential schooling and probable pathological gambling. The participants were 358 Indigenous persons (54.2% women) aged between 18 and 87 years, from two communities and two semi-urban centers in Quebec (Canada). Probable pathological gambling was evaluated using the South Oaks Gambling Screen (SOGS), and sexual abuse and residential schooling were assessed with dichotomous questions (yes/no). The results indicate an 8.7% past-year prevalence rate of pathological gambling problems among participants, which is high compared with the general Canadian population. Moreover, 35.4% were sexually abused, while 28.1% reported having been schooled in a residential setting. The results of a logistic regression also indicate that experiences of child sexual abuse and residential schooling are associated with probable pathological gambling among Indigenous Peoples. These findings underscore the importance of using an ecological approach when treating gambling, to address childhood traumas alongside current addiction problems.  相似文献   

基于消息的单片机编程方法   总被引：1，自引：0，他引：1  

贺海峰 《广西大学梧州分校学报》2005,15(1):83-84

在单片机MCS-51的开发运用中，通常要使用各种中断。如中断服务程序执行时间过长，当有另外的中断发生时，单片机就不能及时地进行处理，特别是对MCS-51这样的只有两级中断优先级的单片机更是这样。借鉴Windows编程的原理，在单片机编程中引入消息的概念，将中断产生的标志作为消息，而数据处理则放在消息循环中进行，这样一方面减少了中断服务程序的长度，提高了响应中断的速度；另一方面又不影响数据的处理。  相似文献   

小波变换在信号奇异性检测中的应用     

孙成祥  晁勤 《科技广场》2006,(11):11-13

小波变换突破了传统傅里叶变换等信号处理方法的限制,在时域和频域上可同时对信号实现局部化处理,这更符合信号非平稳的变频带结构特征,因而在信号检测奇异性等方面具有广泛的应用价值。本文简要地介绍了小波应用在信号奇异性检测方面变换的基本原理,并通过仿真实验进行了验证。  相似文献   

Deterioration of Yungang Grottoes: Diagnosis and research   总被引：2，自引：0，他引：2  

Ren Zhi Liu  Bing Jian Zhang  Hui Zhang  Mei Feng Shi 《Journal of Cultural Heritage》2011,(4):494

Yungang Grottoes, in Datong City of Shanxi Province, China, as the state-level key cultural relic preservation organ, have been subjected to severe degradation due to natural and human factors over the years. Since January 2010, site investigation and research on Yungang Grottoes, assisted by the Xi’an Relics Protection Center and Yungang Grottoes Cultural Research Institute, have been carried out in the laboratory of cultural relics conservation materials in Zhejiang University. Our investigation of the deterioration characteristics of these grottoes is presented here. The paper describes about 12 types of diseases in detail represented by dust deposit, salt crystallization and black crust. Relevant samples have been collected and analyzed by means of SEM, FT-IR, XRD and EDAX to study the potential hazard to the sandstones and conservation methods, which could be used to help guide remediation efforts directed at reducing the weathering problem.  相似文献   

A multilevel approach for the damage assessment of Historic masonry towers     

Anna Anzani  Luiga Binda  Alberto Carpinteri  Stefano Invernizzi  Guiseppe Lacidogna 《Journal of Cultural Heritage》2010,11(4):387-470

In the paper some case studies of damaged towers in Italy are presented: the Tower Masserano of Palace Ferrero - La Marmora at Biella, the bell tower of the Collegiata of San Vittore at Arcisate, and three medieval towers in Alba. A methodology is put forward for combining laboratory and nondestructive testing methods with monitoring systems in order to reach the goal of evaluating the state of conservation of historic towers and its evolution in time.  相似文献

儿童半月板损伤的诊断与手术效果     

杨泉森  王粉娣 《浙江体育科学》1994,(1)

作者报道了1957～1990年间收治并经手术证实儿童半月板损伤的48例临床资料.着重评价了传统诊断方法的要点及价值,讨论了仪器检查的价值与适应症.随诊1～36年.虽然临床疗效比较理想,但术后关节退变出现早而严重,故对儿童半月板全切除术应持慎重态度.藉助关节镜早期诊断和治疗,最大限度保留半月板是努力方向.  相似文献   

Patterns of contingent teaching in teacher-student interaction     

Janneke van de Pol  Monique VolmanJos Beishuizen 《Learning and Instruction》2011,21(1):46-57

The present study aimed at investigating the process of scaffolding in a naturalistic setting with focus on a key aspect of scaffolding, namely contingency. Three Social Studies teachers in innovative prevocational schools were observed and interviewed. A coding scheme for the measurement of scaffolding was developed which revealed different patterns of contingent and non-contingent teaching amongst the teachers. In general these teachers of innovative schools showed little contingent teaching. Not adapting the support to students' current understanding and barely diagnosing the students' understanding appeared to be characteristic of this scarcity of non-contingent teaching.  相似文献
