This study examined associations between maltreatment and early developmental vulnerabilities in a population sample of 68,459 children (Mage = 5.62 years, SD = .37) drawn from the Australian state of New South Wales, using linked administrative data for the children and their parents (collected 2001–2009). Associations were estimated between (a) any maltreatment, (b) the number of maltreatment types, and (c) the timing of first reported maltreatment and vulnerability and risk status on multiple developmental domains (i.e., physical, social, emotional, cognitive, and communication). Pervasive associations were revealed between maltreatment and all developmental domains; children exposed to two or more maltreatment types, and with first maltreatment reported after 3 years of age, showed greater likelihood of vulnerability on multiple domains, relative to nonmaltreated children. 相似文献

Item response time data were used in investigating the differences in student test-taking behavior between two device conditions: computer and tablet. Analyses were conducted to address the questions of whether or not the device condition had a differential impact on rapid guessing and solution behaviors (with response time effort used as an indicator) as well as on the time that students spent on the test (reading, mathematics, and science) or a given item type (such as drag-and-drop and fill in blank). Further analyses were conducted to examine if the potential impact of device conditions varied by gender and ethnicity groups. Overall there were no significant differences in response time effort related to device, although some differences related to item type and test sequence were noted. Students tended to spend slightly more time when taking the tests and certain types of items on the tablet than on the computer. No interactions of device with gender or ethnicity were observed. Follow-up research on the item time thresholds is discussed. 相似文献
