An increasing number of scholars are being trained in the field of mind, brain, and education (MBE), yet discussions of trainees' needs and how to meet them are rare. We, the inaugural International Mind, Brain, and Education Society (IMBES) Trainee Board, identify three broad needs of MBE trainees: guidance and support, greater access to and connections among the MBE community, and professional development. We report a first step to address these needs: a daylong trainee conference, which included sessions to foster connections among trainees, provide mentorship from MBE leaders, and provide knowledge and skill building for careers. Attendees' survey results suggest the conference successfully supported trainees' development. As substantial trainee needs remain, we offer specific ways that principal investigators, institutions, funding agencies, future IMBES trainee boards, and the MBE community can further address trainees' needs to support early‐career development and strengthen the MBE field generally. 相似文献

Teacher expectancies can have an impact on students' academic achievement. These expectancies can be based on diverse student characteristics, only one of which is past academic performance. The present study investigated three student individual differences that teachers may use when forming academic expectancies: the sex of the student, the family socioeconomic status (SES) of the student, and the student's after-school activities. Results indicated teachers held higher grade, graduation, and college attendance expectancies for females than for males and for middle-SES than low-SES students. Also, students who participated in extracurricular activities were expected to achieve more academically than either students who were employed after school or who did nothing after school. The latter two groups did not elicit different teacher expectancies. Interactions revealed that (a) lowest expectations were held for low-SES males who did nothing after school and (b) the difference in graduation expectancies between the SES groups was only half as great for students who took part in extracurricular activities than it was for students who had no involvements after school or who had jobs.

OBJECTIVE: Although social maladjustment appears to be common among abused children, negative outcomes are not inevitable. This investigation was designed to determine whether ethnicity and features of the parenting context predicted children's social adjustment, and whether the strength and direction of these relations differed for abused and nonabused children. METHOD: Participants included 78 physically abused and 75 demographically matched nonabused children and one of their parents. Observations of parenting were used to measure parental sensitivity, and parent self-reports of depression were obtained using the SCL-90-R. Children's peer social adjustment was measured by teacher report. RESULTS: Using regression analysis, we tested whether each potential protective or vulnerability factor interacted with abuse status in prediction of social adjustment. Results indicated main effects of ethnicity and sensitivity for prosocial behavior, and a main effect of sensitivity for aggression. In addition, there was a significant interaction of ethnicity and abuse status for aggression such that there was a significant difference between abused and nonabused European American children but not between abused and nonabused African American children. CONCLUSIONS: Findings indicate that risk for aggressive behavior among abused children might be culturally specific rather than universal. In addition, results point to beneficial effects of parental sensitivity for maltreated children. 相似文献

This paper considers vibration control of a single mass flexible rotor on damped flexible supports with active feedback control. Both proportional and derivative feedback control are utilized. Free vibrations and unbalance response of the rotor-control system are determined. The effect of proportional control is to increase the critical speed of rotating machinery while the effect of derivative control is to reduce the amplitude of vibration. Generally larger ratios of support stiffness to shaft stiffness require larger values of control parameters to produce given amplitudes of vibration. 相似文献

This study quantifies racial/ethnic differences in Medicaid expenditures on psychotropic drugs among a national sample of children with suspected maltreatment. We linked 4,445 child participants in the National Survey of Child and Adolescent Well-Being (NSCAW) – consisting of children investigated for suspected abuse and neglect – to their Medicaid claims obtained from 36 states. We used propensity score matching to construct a comparison group of children without known child welfare involvement, and estimated two-part generalized linear models to examine differences in annual psychotropic drug expenditures per child between children of different races/ethnicities. When compared to a matched sample of children, African American and Latino children incur $292 and $144 less expenditures on psychotropic drugs, respectively, than white children. Among NSCAW children alone, African American children display $614 less spending on psychotropic drugs when compared to white children. Racial/ethnic differences in expenditures on psychotropic drugs occur among all children on Medicaid, but the differences are especially pronounced among African American children in contact with the child welfare system. These findings demonstrate that policymakers will need to pay special attention to the needs of children of color as Medicaid expansions proceed nationwide. 相似文献

The generalized dynamic equations of motion have been obtained by the direct stiffness method for multimass flexible rotor bearing systems including the effects of gyroscopic moments, disc skew, and rotor acceleration. A set of undamped critical speed mode shapes calculated from the average horizontal and vertical bearing stiffness is used to transform the equations of motion into a set of coupled modal equations of motion. The modal equations are coupled by the generalized bearing coefficients and the gyroscopic moments. An analysis using only undamped critical speeds or decoupled modal analysis assuming proportional damping may lead to erroneous results. This paper presents a rapid method of calculating rotor resonance speeds with their corresponding amplification factors, stability and unbalance response of turborotors. Examples of the application of this modal approach are presented and results are compared to those of other methods such as matrix transfer analysis. 相似文献
