Child maltreatment as a risk factor for opioid dependence: Comparison of family characteristics and type and severity of child maltreatment with a matched control group

ObjectiveTo examine the prevalence, characteristics and risk factors for child maltreatment among opioid-dependent persons compared to a community sample of similar social disadvantage.MethodThe study employed a case-control design. Cases had a history of opioid pharmacotherapy. Controls were frequency matched to cases with regard to age, sex and unemployment and were restricted to those with a lifetime opioid use of less than five times. The interview covered child maltreatment, family environment, drug use and psychiatric history.ResultsThis study found a high prevalence of child maltreatment among both cases and controls. Despite the elevated prevalence among controls, opioid-dependent males had a higher prevalence of physical and emotional abuse; female cases had a higher prevalence and greater severity of sexual abuse. The prevalence of neglect was similar for both groups. Early parental separation was more prevalent among female cases compared to female controls; otherwise the prevalence of the risk factors was comparable for both groups. The risk factors significantly associated with child maltreatment were also similar for both cases and controls.ConclusionsGiven the documented association between child maltreatment and adult mental disorder, child maltreatment may be an important antecedent of current psychological distress in persons presenting to treatment for opioid dependence. Apart from a possible association between early parental separation and sexual abuse among female cases, the increased prevalence of child maltreatment associated with opioid dependence did not appear to be related to differences in early childhood risk factors considered in this paper. Other risk factors may be more pertinent for those with opioid dependence.Practice implicationsThe high prevalence of child maltreatment among the opioid-dependent sample has implications for the assessment and treatment of clients presenting with opioid dependence. Assessment of child maltreatment history could help inform the development of individual treatment plans to better address those factors contributing to the development and maintenance of opioid dependence. Specifically, management of co-morbid mental disorder associated with child maltreatment could be the focus of relapse prevention programmes and also have a positive influence on treatment retention.     

线性时态逻辑的决策问题复杂性

不同的时态逻辑能够适应不同的推理任务.为了符合应用,关于时间的模型从离散的自然数和整数,延伸到稠密的线性实数,甚至扩展到区间代数和树代数.如果简单的时态连接词的表达力已经足够,就只需使用这些简单的时态连接词来构造的时态逻辑.在能够承担降低运算速度的风险下,我们可以为实现更强的表达力而使用更多的连接词,也可以加上度量信息或者固定点.作者近期提出了一个令人惊讶的结论:建立在实数时间上的具有足够表达力的语言和基于自然数离散时间流的传统简单算子,它们推理的计算复杂性是一样的.在这篇论文中,作者试图对建立在标准时态连接词和线性时间流的普通类上的时态逻辑中所有决策问题的计算复杂性作新的说明.尤其是,文中指出,所有标准逻辑在PSPACE中都存在决策问题.     

Social justice and school linkages in teacher education programmes

This paper investigates current research into the role of education in combating social injustice, assembles this research to indicate key features of a teacher education programme that would assist education for social justice, and links these features to one innovative university teacher education programme to ascertain some of the practical difficulties in establishing such a programme. The research indicated key approaches that would enhance the probability that graduates from teacher education programmes will be able to pursue social justice initiatives.     

The impact of curriculum change on health sciences first year students’ approaches to learning

This study aimed to use a learning inventory (the Approaches and Study Skills Inventory for Students, ASSIST) to measure the impact of a curriculum change on students’ approaches to learning in two large courses in a health sciences first year programme. The two new Human Body Systems (HUBS) courses were designed to encourage students to take a deep approach to learning. ASSIST was completed by 599 students enrolled in a biology class in 2006 that was part of the old curriculum, and by 705 students at the beginning and end of the new HUBS courses in 2007. Changes in students’ approaches to learning over time were examined. The ASSIST scores for both HUBS courses reflected the dominance of a surface approach, followed by a strategic and then a deep approach. However, by the end of the year, students were taking a deep and strategic approach to their studies to a greater extent, and a surface approach to a lesser extent. Moreover, students enrolled in the new course adopted a deep approach to their studies to a significantly greater degree than those studying the old curriculum. Despite the predominance of a surface approach, the results suggest that it is possible to bring about small but significant positive changes in students’ learning behaviour in a very large class through curriculum change. The proportion of students preferring a surface approach, and results showing that high performance on the final exam was significantly correlated with a surface approach, probably reflected contextual factors, including assessment, and is the focus of ongoing curriculum development.     

Sexual choreographies of the classroom: movement in sexuality education

This paper is interested in thinking more about sexuality education at school. As such, it is concerned with a mundane and unacknowledged feature of the sexuality classroom – the mapping of movement. While human movement is a familiar focus of educational research, the movement of things is not. With reference to Barad’s concept of intra-activity, the paper maps human-non-human movements and characterises these as a sexual choreography of schooling. Instead of asking what does movement mean or reveal about sexuality education, I attend to the event movement inaugurates. Predominantly theoretical, the paper weaves together ideas from conventionally disparate disciplinary fields. These include Edensor’s concept of rhythm from geography, Eggermont’s notion of the choreography of schooling from education, and Barad’s spacetimemattering from quantum physics. This theorisation enables a recognition of movement as a force in human-non-human classroom intra-actions implicated in the becoming of sexuality education as event.     

Integrating curriculum: a case study of teaching Global Education

Despite widespread support for integrated approaches to teaching, classroom practice reveals a lack of implementation. This paper explores challenges and opportunities in teaching an integrated curriculum, and connects this with the contemporary notion of a twenty-first century curriculum and pedagogy. A case study of Global Education (GE) is used to delineate the complexity of issues when teachers attempt to move beyond disciplinary-based teaching approaches. We examine curriculum documents, advice for teachers on curriculum implementation, preservice teachers’ experiences in schools during Professional Experiences and national guidelines for Professional Experience. Through these data, a broad picture emerges of influences on integrating curricula in classrooms. Opportunities to integrate curriculum incorporating twenty-first century pedagogies were limited by pressures on teachers with preservice teachers rarely exposed to authentic integration. Teachers’ professional standing requires clear guidelines, which allow them to pursue important twenty-first century content and skills , for young citizens and this must begin in preservice education.     

Spelling error interpretation: beyond the phonetic/dysphonetic dichotomy

If spelling errors are classified simply as auditory or visual, or as phonetically accurate or inaccurate, manifestations of both developmental phenomena and possible linguistic process deficits in spelling may be overlooked or misinterpreted. Phonological process deficits in spelling are more complex than simple phonetic ratings will reflect. Spelling errors may yield useful information about specific language disabilities if linguistically informed criteria for analysis are employed.     

Embryonic auditory experience and maternal call recognition

Peking duck embryos respond selectively to the maternal call of their species on the day before hatching, given normal embryonic auditory experience (the sounds emanating from their siblings and themselves which begin late on Day 24 of development). Groups of Peking embryos were subjected to recordings of either the mallard or the Burmese red jungle fowl maternal call beginning on Day 21 of incubation. Responses to these calls were tested on the day before hatching to determine the effects of the prenatal auditory experience. The responses of those birds exposed to the mallard maternal call were neither attenuated nor enhanced (as compared to the controls) when presented that call; those subjects which were exposed to the jungle fowl maternal call later failed to respond to that call or the mallard maternal call.
