Parent-child interaction and conduct disorder

This paper reviews recent research on the role of parent-child interaction in the etiology of children's conduct disorder. It examines the role of social and family factors in conduct disorder and the possible mechanisms by which these contextual factors might affect parent-child interaction and child problem behavior. A major focus is on research that has compared the patterns of interaction in families with and without conduct-disordered children, using observational methods, in order to test different theoretical explanations about how conduct disorder develops and is maintained. Further research is needed on the neglected area of positive parent-child interaction, which may be just as important as conflictual processes in determining the development of conduct disorder. Theoretical and methodological issues are raised about the problems of determining causality from correlational research, and the possibilities for naturalistic experimental studies are discussed.     

A Primer on College Student Substance Use Disorders Screening,Assessment, and Treatment Planning

Significant numbers of college students experience negative consequences due to their misuse of alcohol and other drugs. For far too many, some of these effects are ruinous of their lives, and for well more than a thousand each year, life ending. This article first provides an overview of the scope of this problem. It then covers both assessment and intervention starting with brief and standard assessment inventories followed by a perspective on comprehensive focused counseling that incorporates an assessment of multiple life areas. A case is made that many students have substance use disorders issues either as primary problems or auxiliary to other concerns. Treatment planning based on a comprehensive approach to change, and the role of ongoing utilization of change measures, is then discussed. A basic premise of the article is that due to a lack of education, training, and exposure, many college mental health practitioners underdiagnose and underattend to the presence of substance use disorders problems. Many clinical staff members have never taken an academic course focused on this treatment issue or have done little by way of continuing education on this topic, so they may lack the knowledge, skills, and aptitudes related to the provision of helpful comprehensive care and consequently make the error of focusing exclusively on the substance use disorders related behaviors.

The influence of lexical and sublexical variables in normal and poor Spanish readers

The main aim of our study was to find out the effect of several lexical and sublexical variables (lexical category, lexical frequency, syllabic structure, and word length) in the acquisition of reading in a transparent language such as Spanish. The second goal of our study was the comparison of the effect of these variables in normal and poor Spanish readers. One hundred and forty children (aged between 6 and 12), twenty of whom were poor readers, were tested using a reading test of 306 items in which we balanced all the variables. The dependent variable was the percentage of correct responses in a decontextualized word reading test. Our results showed that all the above mentioned variables produced a significant effect on the number of errors made by the children. This pattern of results suggests no difference between the processes involved in the reading acquisition of Spanish and those implicated in deep orthographies such as English. Our results also showed no qualitative differences between normal and poor readers. The four variables studied showed the same behaviour in their effect on reading performance for both normal and poor readers, indicating that poor readers also use both the lexical and the phonological route. Our data suggest the universality of the dual route model, independent of the transparency or opaqueness of the different alphabetical languages.     

小学生英语学习策略发展特征的研究

以1303名小学生为研究对象,探讨了不同学校、不同年级、不同性别、小学生英语学习策略的差异。结果表明：（1）普通小学学生的学习策略频率普遍高于名牌小学的学生;在3—5年级学生群体中,年级越高,英语学习策略频率越低,6年级学生英语学习策略水平再次升高,但与3年级相比仍然较低;男生的记忆策略、认知策略、元认知策略使用频率高于女生;（2）学校、年级、性别分别都对小学生英语学习策略不同维度有不同程度的预测作用,其中,学校对小学生的记忆策略、认知策略、元认知策略、情感策略、社会策略的预测作用最大;在补偿策略上只有年级对其有预测作用。     

HPLC method for amino acids profile in biological fluids and inborn metabolic disorders of aminoacidopathies

Quantification of total and individual amino acids in biological fluids such as plasma, urine and cerebrospinal fluid has an important diagnostic implication in laboratory medicine. The present paper describes protocols for the assay of total amino acids by modified method based on dinitrophenyl and HPLC profile involving pre-column derivatization with o-pthalaldehyde (OPA) derivatization, respectively. The method, based on the alkylation of-SH groups prior to OPA derivatization of amino acids followed by reverse phase high performance liquid chromatography, provide a comprehensive profile of more than twenty amino acids (including-SH group containing) in a single run lasting about 45 minutes. The present study, apart from establishing the normal profile of amino acids in plasma of Indian sub population, also presents HPLC profile for some of the rare amino acidopathies.     

Who is Your Coach?

Initial teacher licensing is intended to provide public assurance of core competence in classroom settings. Core competence's implicit vulnerability is mediocrity. In daily practice, many educators appear satisfied in reaching a merely acceptable level of performance, thus minimizing the period of effortful skill acquisition required to attain core excellence. To transition from core competence to core excellence in instructional settings requires deep learning. Five professional practices reside at the heart of deep learning: a mind-set for continuous learning, an entrenched openness to feedback, deliberate practice, rigorous self-critique of instructional practices, and consistent coaching. Who is your coach?     

Behavior problems in elementary school among low-income boys: The role of teacher–child relationships

The authors identified trajectories of teacher–child relationship conflict and closeness from Grades 1 to 6, and associations between these trajectories and externalizing and internalizing behaviors at 11 years old among low-income, urban boys (N = 262). There were three main findings. Nagin cluster analyses indicated five trajectories for conflict with all children evidencing increases in conflict, and four trajectories for closeness with all children demonstrating decreases in closeness. Trajectories with higher levels of conflict and lower levels of closeness were associated with higher levels of externalizing and internalizing behavior problems at 11 years old. Moreover, conflictual teacher–child relationships exacerbated the effects of externalizing and internalizing behavior problems in early childhood; children with conflictual teacher–child relationships had higher levels of behavior problems in middle childhood relative to children with low conflictual teacher–child relationships. Implications of targeting teacher–child relationships as interventions to help prevent behavior problems are discussed.
