OBJECTIVE: To compare baseline characteristics, service provision, and child placement for infants exposed to cocaine in utero based on postnatal screening results. METHODS: We studied a retrospective cohort of 40 consecutive drug-exposed, but seemingly healthy term infants who underwent urine drug screening in the newborn nursery of a community hospital. Using clinical and service agency data, two cocaine-exposed cohorts were compared (a) screen-positive at birth (n = 22) versus (b) screen-negative at birth (n = 18). RESULTS: Both cocaine-exposed groups had similar infant birth weights, levels of paternal involvement, maternal ages, gravidity, parity, and lengths of gestation. Mothers in both groups had similar histories of prostitution, poor home environment, drug use, and prenatal drug rehabilitation. Mothers of screen-positive infants were more likely than mothers of screen-negative infants to have other children in foster care (27% vs. 6%, p = .07), to have experienced previous interventions by child protective services (CPS) (55% vs. 17%, p < .01), to have had no prenatal care (32% vs. 6%, p = .09), and fewer prenatal visits (4.7 vs. 8.6, p = .02). Compared to screen-negative infants, more screen-positive infants were referred to a high-risk infant tracking program (91% vs. 6%), referred to CPS (100% vs. 33%), placed outside the mother's home (50% vs. 22%), and had their mothers referred to drug rehabilitation (36% vs. 11%), (p < .01 for each). By 1 year of age, support services differed little between exposed cohorts. However, 6 of 22 screen-positive infants were in foster care and 3 were placed for adoption, while only 1 of the 18 screen-negative infants was in foster care and only 1 had been placed for adoption. There were no services available in this community to provide coordinated or comprehensive services or drug treatment specific to the needs of drug using mothers and drug exposed infants. CONCLUSIONS: Despite similarities between cocaine-exposed infants cared for in a normal newborn setting (with and without positive urine drug screens at birth), differences in referral services were noted. More striking than these differences was that services for families with drug-exposed infants are inadequate to even meet the needs of those families in our setting deemed to be at highest risk. Neonatal drug screening needs to be paired with effective services.  相似文献

Evaluating Assistive Technology in Early Childhood Education: The Use of a Concurrent Time Series Probe Approach     

Howard P. Parette  Craig Blum  Nichole M. Boeckmann 《Early Childhood Education Journal》2009,37(1):5-12

As assistive technology applications are increasingly implemented in early childhood settings for children who are at risk or who have disabilities, it is critical that teachers utilize observational approaches to determine whether targeted assistive technology-supported interventions make a difference in children’s learning. One structured strategy that employs observations and which has powerful child progress monitoring implications is the concurrent time series probe approach. Requiring multiple performance measures of a child engaged in a targeted task over time—both with and without a specific assistive technology device—the concurrent time series probe approach can be used to evaluate the effectiveness of assistive technology tools in supporting skill acquisition in the classroom. This approach is described in the context of a case study, with accompanying explanations of how to interpret data and make decisions regarding the effectiveness of the technology.  相似文献   

Fostering online social construction of science knowledge with primary pre-service teachers working in virtual teams     

Howard Nicholas  Wan Ng 《Asia-Pacific Journal of Teacher Education》2009,37(4):379-398

As many primary pre-service teachers enter teacher education courses with little science background, it is essential in teacher education courses to provide opportunities for them to learn more science independently. The purpose of this study is to investigate an online pedagogical activity that fosters the social construction of science knowledge by primary pre-service teachers working in small virtual teams. The study investigated how the pre-service teachers collaborated online in virtual teams to complete set tasks, their attitudes toward and beliefs about the effectiveness of the online learning experience, and the types and quality of the resources developed. The findings indicated that the virtual team-produced science resource materials were generally of high quality, with nearly half the number of teams engaging with Web 2.0 technologies (e.g. wikis and blogs) to construct their product. The findings indicated positive attitudes toward the collaborative learning even though beliefs about online learning were mixed.  相似文献   

Better Red than Dead—Putting an End to the Social Irrelevance of Postwar Philosophy of Science     

Don Howard 《Science & Education》2009,18(2):199-220

This paper asks what is necessary in a theory of science adequate to the task of empowering philosophers of science to participate in public debate about science in a social context. It is argued that an adequate theory of science must be capable of theorizing the role of values and motives in science and that it must take seriously the irreducibly social nature of scientific knowledge.

(Un)Critical times? Situating distributed leadership in the field     

Howard Youngs 《Journal of educational administration and history》2009,41(4):377-389

It is time to situate distributed leadership as a critical conceptualisation of school leadership; its popularisation has generally preceded conceptual and empirical development. Over the last 10 years distributed leadership has often been presented as a new construct of school leadership, though critique against education policy reforms and conceptual and historical links to the wider leadership field have generally been underemphasised. The theorisation and research of distributed leadership is currently situated at a critical point in its development; it is at the ‘crossroads’ of where it could dominantly be situated in the field of school leadership. A review of the literature and research suggests that distributed leadership is tending towards an uncritical position that is decoupled from critique of past and present education reforms and predominantly silent on how power relations at the local school level shape leadership activity.  相似文献

Agreement between Polar and SRM mobile ergometer systems during laboratory-based high-intensity,intermittent cycling activity     

Howard T. Hurst  Stephen Atkins 《Journal of sports sciences》2013,31(8):863-868

Abstract

The purpose of this study was to assess the agreement between two mobile cycle ergometer systems for recording high-intensity, intermittent power output. Twelve trained male cyclists (age 31.4 ± 9.8 years) performed a single 3 min intermittent cycle test consisting of 12 all-out efforts, separated by periods of passive recovery ranging from 5 to 15 s. Power output was recorded using a Polar S710 heart rate monitor and power sensor kit and an SRM Powercrank system for each test. The SRM used torque and angular velocity to calculate power, while the S710 used chain speed and vibration to calculate power. Significant differences (P < 0.05) in power were found at 8 of the 12 efforts. A significant difference (P = 0.001) was also found when power was averaged over all 12 intervals. Mean power was 556 ± 102 W and 446 ± 61 W for the SRM and S710 respectively. The S710 underestimated power by an average of 23% with random errors of ?/÷ 24% when compared with the SRM. Random errors ranged from 36% to 141% with a median of 51%. The results indicate there was little agreement between the two systems and that the Polar S710 did not provide a valid measure of power during intermittent cycling activity when compared with the SRM. Power recorded by the S710 system was influenced greatly by chain vibration and sampling rates.  相似文献   

Stimulus Velocity,Duration and Uncertainty as Determiners of Response Structure and Timing Accuracy     

Charles H. Shea  John B. Krampitz  Homer Tolson  Alan A. Ashby  Rose M. Howard  William S. Husak 《Research quarterly for exercise and sport》2013,84(1):86-99

Abstract

The present experiments examined the effects of stimulus velocity, stimulus duration, and stimulus uncertainty on the spatial-temporal structure and timing accuracy of coincident timing responses. The results of Experiment 1 indicated that the response structure for aimed movements differed from that of ballistic movements but response accuracy was comparable for both movement conditions. However, when information concerning the stimulus velocity was provided, the responses to the faster stimuli (i.e., stimuli of shorter duration) appeared to be “speeded up” copies of those to slower stimuli and response accuracy increased as the stimulus velocity increased (i.e., stimulus duration decreased). When the stimulus velocity was not known, subjects initiated a common response for approximately 260 msec and response accuracy appeared to decrease as the stimulus velocity increased (i.e., stimulus duration decreased). Experiment 2 indicated that the stimulus duration rather than the stimulus velocity was the major determiner of both the spatial-temporal structure and timing accuracy and that a very fast and a very slow stimulus will be responded to similarly when the stimulus duration remains constant.  相似文献   

Do special education teachers use IEPs to guide instruction?   总被引：1，自引：0，他引：1  

Howard Margolis  Lee Ann Truesdell 《The Urban Review》1987,19(3):151-159

Teachers in a large urban school system were surveyed with a self-administered questionnaire and a modified nominal group technique to assess their views about IEPs and identify impediments to implementing the IEPs of their students. Teachers indicated that they viewed the IEP more as a legal requirement than as an important guide for planning instruction. Frequently they were not involved in the development of their students' IEPs. The article specifies reasons given by teachers for not adhering to their students IEPs and provides recommendations for increasing teacher involvement in IEP preparation. It also presents recommendations for improving instructional conditions and practices which may facilitate IEP implementation.  相似文献
