Adolescent maltreatment and its impact on young adult antisocial behavior

STATEMENT OF PROBLEM: Childhood maltreatment is known to be a risk factor for a range of later problems, but much less is known about adolescent maltreatment. The present study aims to investigate the impact of adolescent maltreatment on antisocial behavior, while controlling for prior levels of problem behavior as well as sociodemographic characteristics. METHODS: Data are from the Rochester Youth Development Study, a cohort study of the development of problem behaviors in a sample of 1,000 urban youth followed from age 13 into adulthood. Subjects include 68% African American, 17% Hispanic, and 15% White youth. This analysis includes a maximum of 884 subjects, of whom 9.3% had substantiated maltreatment reports in adolescence. Among the maltreated adolescents, 14 experienced sex abuse, 36 experienced physical abuse, and 32 were neglected or emotionally abused. Outcomes explored in late adolescence (ages 16-18) and young adulthood (ages 20-22) include arrest, self-reported general and violent offending, and illicit drug use. Control variables include prior levels of these outcomes as well as sociodemographic characteristics like poverty, parent education, and caregiver changes. RESULTS: Logistic regression analysis determined that experiencing any substantiated maltreatment during adolescence increases the odds of arrest, general and violent offending, and illicit drug use in young adulthood, even controlling for sociodemographic characteristics and prior levels of problem behavior. Different types of adolescent maltreatment, including neglect, appear to produce similar adverse behavioral consequences. CONCLUSIONS: Adolescent maltreatment necessitates increased attention in view of its enduring and potentially wide-ranging impact on the life span.     

Multiple hedonic memory: Memory for more than one hedonic event in rats

In each of two investigations, rats ran in a runway to obtain varying quantities of food pellets presented in a fixed order, such as 20-0-20. The major finding was that rats ran faster on a 0-pellet trial if that trial was followed shortly by a 20-pellet trial (e.g., 20-0-20 series) than if it was not (e.g., 20-0 series). This finding was obtained both within groups (Experiment 1) and between groups (Experiment 2), and suggested that the memory of 20 pellets arising from the first trial of the 20-0-20 series was retrieved not only on the second trial of the series, thereby signaling 0 pellets, but on the third trial as well, thereby also signaling 20 pellets. Retrieving the memory of 20 pellets on Trial 3 of the 20-0-20 series apparently resulted in that memory’s elevating speed on Trial 2 of that series.     

Promoting VET teachers’ innovative behaviour: exploring the roles of task interdependence,learning goal orientation and occupational self-efficacy

Changing employer demands, new technological and pedagogical insights are examples of developments which urge Vocational Education and Training (VET) institutes to continually renew and innovate their educational programmes. This, in turn, requires teachers to show innovative behaviour. Our study focuses on the effects of task interdependence on VET teachers’ innovative behaviour. In addition, the mediating roles of learning goal orientation and occupational self-efficacy in this relationship are examined. A two-wave survey study among 342 teachers, from 54 teams of 6 Dutch VET institutes, showed that task interdependence enhanced teachers’ learning goal orientation, which enhanced their engagement in innovative behaviour over time. Task interdependence also increased teachers’ occupational self-efficacy, which in turn increased their engagement in innovative behaviour. This effect, however, appeared short lived. Apparently, once teachers exceed a certain level of occupational self-efficacy, other variables, like learning goal orientation, play a more important role in sustaining innovative behaviour.     

Exploring the digital natives among pre-service teachers in Turkey: a cross-cultural validation of the Digital Native Assessment Scale

This study aims to explore the digital natives among a sample of pre-service teachers and in the process, examine the validity of a Turkish adaptation of the digital native assessment scale (DNAS) [Teo, T., & Fan, X. (2013). Coefficient alpha and beyond: Issues and alternatives for educational research. The Asia-Pacific Education Researcher, 22(2), 209–213]. Five hundred and fifty-seven participants completed a survey questionnaire in Turkish measuring their responses on the DNAS, developed from a proposed four-factor research. Confirmatory factor analysis and multiple indicators, multiple causes modelling were used to analyse the data and an acceptable fit was found, suggesting that the DNAS is a valid measure for participants who are older living in another culture. While the pre-service teachers had mostly regarded themselves as digital natives, significant differences were only found by years of computer use and perceived competence but no significant differences were found for gender and age.     

Making Real Analysis Relevant to Secondary Teachers: Building Up from and Stepping Down to Practice

Future teachers often claim that advanced undergraduate courses, even those that attempt to connect to school mathematics, are not useful for their teaching. This paper proposes a new way of designing advanced undergraduate content courses for secondary teachers. The model involves beginning with an analysis of the curriculum and practices of school mathematics and its teaching, and then using those to build up to the advanced mathematics – in this case, real analysis. After developing definitions, examples, theorems, and proofs, the model then reconnects to practice, asking the teachers to translate ideas from real analysis in ways that are appropriate for teaching high school content to students. To illustrate the model, we provide and discuss two example tasks.     

Recent Developments in Young-Earth Creationist Geology

Young-earth creationism has undergone a shift in emphasis toward building of historical models that incorporate Biblical and scientific evidence and the acceptance of scientific conclusions that were formerly rejected. The RATE Group admitted that massive amounts of radioactive decay occurred during earth history but proposed a period of accelerated decay during Noah’s Flood to fit the resulting history into a young-earth timeframe. Finding a mechanism for the acceleration and dealing with the excessive heat and radiation it would generate posed major problems for the project. Catastrophic plate tectonics was proposed to explain continental movements in a short timeframe and serve as a trigger for Noah’s Flood, but other creationists rejected the idea citing hopeless chronological problems. Creationists have also sought to explain the order of the fossil record and the Ice Age in a young-earth timeframe. An examination of these efforts demonstrates the anti-scientific nature of using the Bible as a non-negotiable framework for earth history.
