Children's insecure representations of the interparental relationship and their school adjustment: the mediating role of attention difficulties

This study examined the role of attention difficulties as a mediator of associations between children's insecure representations of the interparental relationship and their school adjustment in a sample of two hundred and sixteen 6-year-old children. Consistent with hypotheses, findings from structural equation models indicated that observer ratings of children's insecure representations of interparental relationships in a story completion task predicted computerized task assessments and parent reports of children's attention difficulties 1 year later. Children's attention difficulties, in turn, were associated with concurrent levels of school problems and increases in school problems over a 1-year period as indexed by teacher reports. Attention difficulties accounted for an average of 34% of the association between insecure internal representations and school problems.     

Risk factors for speech delay of unknown origin in 3-year-old children

One hundred 3-year-olds with speech delay of unknown origin and 539 same-age peers were compared with respect to 6 variables linked to speech disorders: male sex, family history of developmental communication disorder, low maternal education, low socioeconomic status (indexed by Medicaid health insurance), African American race, and prolonged otitis media. Abnormal hearing was also examined in a subset of 279 children who had at least 2 hearing evaluations between 6 and 18 months of age. Significant odds ratios were found only for low maternal education, male sex, and positive family history; a child with all 3 factors was 7.71 times as likely to have a speech delay as a child without any of these factors.     

Beware! Uncle Sam has Your DNA: Legal Fallout from its Use and Misuse in the U.S.

Technology has provided state and federal governments with huge collections of DNA samples and identifying profiles stored in databanks. That information can be used to solve crimes by matching samples from convicted felons to unsolved crimes, and has aided law enforcement in investigating and convicting suspects, and exonerating innocent felons, even after lengthy incarceration. Rights surrounding the provision of DNA samples, however, remain unclear in light of the constitutional guarantee against "unreasonable searches and seizures" and privacy concerns. The courts have just begun to consider this issue, and have provided little guidance. It is unclear whether the laws governing protected health information are applicable to the instant situation, and if so, the degree to which they apply. DNA databanks are not uniformly regulated, and it is possible that DNA samples contained in them may be used for purposes unintended by donors of the samples. As people live their lives, they leave bits of their DNA behind. They cannot be assured that these tiny specimens will not be taken or used against their will or without their knowledge for activities such as profiling to measure tendencies such as thrill-seeking, aggressiveness, or crimes with threatening behavior. Existing racial or ethnic discrimination and profiling may also encompass genetic discrimination and profiling, creating societal class distinctions. This article will explore the constitutionality of collecting genetic materials, the ethics of such activities, and balance the social good in solving crime and deterrence against the individual's security, liberty, and privacy.     

Supporting Student Learning through Instructional Videos in Business Statistics

While statistics is an essential topic for business students, many students experience barriers to successful learning due to anxiety, motivation, or difficulty with quantitative understanding. This research examines the use of online videos with an effort to explore the relationship between student characteristics, video usage, and course performance measures. In addition, the study examines student perceptions of the supplemental resources in an effort to examine the efficacy related to student learning and performance. This study seeks to confirm previous research regarding the benefit of supplemental video resources and extend the knowledge base by understanding the impact for various types of students (e.g., level of course, level of previous academic performance, etc.). The study found that the use of the video resources varies based on students’ previous math performance and the difficulty of the material. Student ratings indicate that the videos were helpful in learning the content and that they provided an important resource when students needed additional tools to master the material. Analysis of the results provides implications for understanding how different students use online videos and offers recommendations for educators and researchers about how to enhance student success in difficult statistics coursework.

Test stimuli: Representational level with middle class and head start children

Low income and middle income 4- and 5-year old children were shown stimuli in three forms: objects, colored pictures, and black and white line drawings taken from commonly used assessment instruments, and were asked to label the stimuli. Results indicated that both groups of children labeled the objects more successfully than the pictures, although this discrepancy was greater for the low income children. In addition, order of presentation influenced labeling performance. These results suggest that attention be paid to the representational level of materials used with young children in testing and educational settings.
