The Role of Preschool Relational and Physical Aggression in the Transition to Kindergarten: Links With Social-Psychological Adjustment

Research Findings: The transition to kindergarten has important ramifications for future achievement and psychosocial outcomes. Research suggests that physical aggression may be related to difficulty during school transitions, yet no studies to date have examined the role of relational aggression in these transitions. This article examines how engagement in preschool physical and relational aggression predict psychosocial adjustment during the kindergarten school year. Observations and teacher reports of aggression were collected in preschool, and kindergarten teachers reported on student–teacher relationship quality, child internalizing problems, and peer acceptance in kindergarten. Results suggested that preschool physical aggression predicted reduced peer acceptance and increased conflict with the kindergarten teacher. High levels of relational aggression, when not combined with physical aggression, were related to more positive transitions to kindergarten in the domains assessed. Practice or Policy: These data lend support to the need for interventions among physically aggressive preschoolers that target not only concurrent behavior but also future aggression and adjustment in kindergarten. Thus, educators should work to encourage social influence in more prosocial ways among aggressive preschoolers.     

Phonological recoding,orthographic decoding,and comprehension skills during reading acquisition

To become skillful readers, children have to acquire the ability to translate printed words letter by letter into phonemic representations (phonological recoding) and the ability to recognize the written word forms holistically (orthographical decoding). Whereas phonological recoding is the key for learning to read and useful for recognizing unknown or low-frequent words, orthographical decoding is often more efficient and takes less time, thus facilitating reading processes on the sentence and text level. Several studies with English-speaking children provided evidence for the relevance of the two routes but the question whether and to what extent both word recognition skills contribute to reading comprehension in young German readers requires further clarification. Based on data from a cross-sectional study with German primary school children we investigated whether and to what extent both types of word recognition skills are associated with sentence (N = 666) and text comprehension skills (N = 149) and how these relationships develop from Grade 2 to 4. The results indicate that both phonological recoding skills and orthographical decoding skills are important for reading comprehension skills. Their relative weight does not change across grade levels.     

But I’m Married: Understanding Relationship Status and College Students’ Sexual Behaviors

Sexual health programs on college campuses are often directed toward single individuals with a focus on sexual risk. Using a sample of college students, this study examines how relationship status relates to sexual behaviors and may be a factor for sexual risk. Based on the study's results, expansion of sexual health programming on college campuses to include those married and in committed relationships is justified.     

On modeling and analyzing multi-agent systems using n-calculus

Dynamic architecture of multi-agent systems （MAS） is important for critical systems. As the existing formal specifications of MAS cannot describe its dynamic architecture, a formal approach using n-calculus is presented, which is suited for the describing and analyzing of concurrent MAS with dynamic topology, n-calculus describes the belief-desireintention （BDI） model that represents agent＇s mental states and provides many useful facilities to analyze MAS model such as deadlock, behavior equivalence, and model checking. To illustrate the favorable representation capability of n-calculus, an example of dynamic multi-agent systems in e-commerce is provided. Finally, by using an existing n-calculus supporting tool, MAS model and some key behaviors properties are analyzed and verified.     

Parent and Child References to Letters During Alphabet Book Reading: Relations to Child Age and Letter Name Knowledge

Research Findings: The purpose of this study was to examine the frequency of extratextual references to letters made by parents and preschoolers during shared reading of an alphabet book. The frequency of letter references was also examined in relation to child age and knowledge of letter names. Participants consisted of 44 preschoolers and their primary caregivers. Videotaped book-reading data were transcribed verbatim and coded for their inclusion of 14 types of letter references (e.g., naming requests, labels, repetitions). Significant findings included the following: Parent labels were significantly correlated with child age; and child knowledge of letter names was significantly correlated with parent naming requests, corrections, and repetitions, and child answers and initiations. Practice or Policy: Findings are discussed in reference to the literature regarding parental sensitivity to child age and knowledge in educational interactions with their child.     

Measuring Teacher–Child Relationships in the Greek Kindergarten Setting: A Validity Study of the Student–Teacher Relationship Scale–Short Form

Research Findings: The present study was designed to examine the factorial validity of the Student–Teacher Relationship Scale–Short Form (STRS-SF; R. C. Pianta, 2001 Hamre, B. K. and Pianta, R. C. 2001. Early teacher-child relationships and the trajectory of children's school outcomes through eighth grade.. Child Development, 72: 625–638. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) and its invariance across gender in the Greek educational context. The STRS-SF comprises 15 items that measure 2 dimensions of teacher–child relationships: Closeness and Conflict. Fifty-six kindergarten teachers completed the STRS-SF about their students (n = 336). A 2-factor model with correlated latent factors was postulated and tested. Confirmatory factor analysis procedures showed marginal fit to the data (comparative fit index [CFI] = .902, root mean square error of approximation [RMSEA] = .066). The fit of the model was further improved by adding 2 error covariances (CFI = .931, RMSEA = .056). Cronbach's alpha coefficient showed adequate internal consistency for Closeness (α = .72) and Conflict (α = .82). In addition, there was a moderate negative association between the 2 subscales (r = ?.38). Examination of STRS-SF invariance showed that it was manifested in the same way across gender. Practice or Policy: The findings of the present study, which was conducted in a cultural context different from the one in which the STRS-SF was developed, seem to support the instrument's factorial validity and equivalence across gender.
