English Learners (ELs), students from non-English-speaking backgrounds, are a fast-growing, understudied, group of students in the U.S. with unique learning challenges. Cognitive flexibility—the ability to switch between task demands with ease—may be an important factor in learning for ELs as they have to manage learning in their non-dominant language and access knowledge in multiple languages. We used functional MRI to measure cognitive flexibility brain activity in a group of Hispanic middle school ELs (N = 63) and related it to their academic skills. We found that brain engagement during the cognitive flexibility task was related to both out-of-scanner reading and math measures. These relationships were observed across the brain, including in cognitive control, attention, and default mode networks. This work suggests the real-world importance of cognitive flexibility for adolescent ELs, where individual differences in brain engagement were associated with educational outcomes. 相似文献

This paper reports the results of a study comparing college freshmen with learning disabilities (LD) and freshmen with no
learning disabilities (NLD). Four data collections over one academic year were completed on a total of 72 students (LDn=39; NLDn=33). Results of the study indicated differences between groups in their initial choice of living accommodations and in the
changes made over the year: the overall trend was for students with LD to become more dependent on their families, while students
with NLD were becoming less dependent on their families. With regard to academics, students with LD reported spending significantly
less time in study and course preparation, as well as greater pessimism about success in coursework. Despite their pessimism,
the actual GPA attainment of students with LD was similar to that of NLD peers. Whereas both groups initially predicted it
would be easy to adjust to the academic and social nature of college, students with learning disabilities ultimately reported
being dissatisfied with the social climate on campus. No differences were found between LD and NLD students regarding their
motivation for attending college, or their plans for final degree attainment. 相似文献

Crisis communication research rarely highlights the voices of marginalized publics or their advocates whose interests are affected by crisis situations. We take a different approach by using a response to a natural disaster to expand our theorizing about crisis situations beyond those that hurt the bottom line. Using official statements from Senators Landrieu and Obama about events surrounding Hurricane Katrina as texts for analysis, we demonstrate how they used transcendence, rhetorically, and appropriated the Bush administration's key term—security—to garner more support for their positions, Katrina sufferers, and relief efforts. Implications of this strategy serve to broaden crisis communication theorizing, and to provide insights into ways to strengthen the quality of crisis emergency response planning and response protocols. 相似文献

This study examined the biological processes associated with foster mother–infant bonding. In an examination of foster mother–infant dyads (N = 41, mean infant age = 8.5 months), foster mothers' oxytocin production was associated with their expressions of behavioral delight toward their foster infant and their average P3 response to images of all infant faces in the first 2 months of the relationship. Three months later, foster mothers' oxytocin production was still associated with delight toward their foster infant and was also specifically associated with their P3 response to an image of their foster infant. Similar to biologically related mothers and infants, oxytocin appears to be associated with foster mothers' brain activity and caregiving behavior, with patterns suggestive of bond formation. 相似文献

We interviewed racially/ethnically diverse, early career public relations practitioners. By asking participants to reflect on their collegiate social and educational development, we unearth contributing factors to these individuals’ success both in college and in their professions to date. Respondents desired much more in-school training and technical skill acquisition than they were provided. Respondents also alluded to ways that the female/male composition of the undergraduate classroom affected their educational environment and student learning experiences. Findings are used to address the extent to which the educational/prepare-students-for-industry dialectic should be addressed by communication faculty and administrators. 相似文献

This study underscored the importance of addressing the well‐being of college students of Asian descent, because these students had higher rates of depression and lower positive feelings about their ethnic group compared with students of European descent, as measured by the Affirmation subscale of the Ethnic Identity Scale. Affirmation mediated the depression difference between these groups. Within the Asian group, affirmation and depression were inversely correlated, and this relationship was mediated by acculturative stress. 相似文献

The manipulation of ribosomal RNA (rRNA) extracted from E. coli cells by dielectrophoresis (DEP) has been demonstrated over the range of 3 kHz-50 MHz using interdigitated microelectrodes. Quantitative measurement using total internal reflection fluorescence microscopy of the time dependent collection indicated a positive DEP response characterized by a plateau between 3 kHz and 1 MHz followed by a decrease in response at higher frequencies. Negative DEP was observed above 9 MHz. The positive DEP response below 1 MHz is described by the Clausius-Mossotti model and corresponds to an induced dipole moment of 3300 D with a polarizability of 7.8×10(-32) F m(2). The negative DEP response above 9 MHz indicates that the rRNA molecules exhibit a net moment of -250 D, to give an effective permittivity value of 78.5 ε(0), close to that of the aqueous suspending medium, and a relatively small surface conductance value of ～0.1 nS. This suggests that our rRNA samples have a fairly open structure accessible to the surrounding water molecules, with counterions strongly bound to the charged phosphate groups in the rRNA backbone. These results are the first demonstration of DEP for fast capture and release of rRNA units, opening new opportunities for rRNA-based biosensing devices. 相似文献

OBJECTIVE: To determine whether the proportion of fractures rated as abusive in children <36 months of age evaluated at a regional pediatric hospital increased over a 24-year period from 1979 to 2002. Fractures were chosen as an example of serious injuries in young children. METHODS: Medical records were abstracted for all children <36 months of age who were seen at a single pediatric hospital with a fracture during three time periods: 1979-1983, 1991-1994, and 1999-2002. After reviewing the abstracted and radiographic information, two clinicians (one an expert on child abuse) and two pediatric radiologists each rated the likelihood of abuse using explicit criteria and a seven-point scale from definite abuse to definite unintentional injury. Ratings were done independently; when disagreements occurred, the case was discussed, and a joint rating was agreed upon, if possible. The proportions of cases rated as abuse were compared over the three time periods, and logistic regression was used to calculate adjusted odds ratios (OR). RESULTS: In the early, middle, and late samples, there were 200, 240, and 232 children, respectively, with fractures. The proportion of cases rated as abuse decreased from 22.5% in the early period to 10.0% in the middle period and was 10.8% in the late period (p<.001). When comparing the odds of abuse in the middle and late groups to the odds of abuse in the early group (controlling for age, gender, ethnicity, type of medical insurance, and site of pediatric care), the adjusted ORs were .31 (95% CI=.15, .62) for the middle group and .45 (95% CI=.23, .86) for the late group. Thus, the odds of a given case being rated as abuse decreased by over 50% from the early period to the middle and late time periods. No statistically significant difference was found when comparing the odds of abuse for the middle group to those of the late group, OR: 1.46 (95% CI=.69, 3.08). CONCLUSIONS: The proportion of abusive fractures in young children decreased substantially from 1979-1983 to 1991-1994 and 1999-2002 at a major pediatric hospital. We speculate that this decrease may reflect early recognition of less serious forms of maltreatment and the availability of services to high-risk families. 相似文献
