Effects of delayed retention on multiple-choice test performance     

Gary Phye  Joseph Gugliemella  Janet Sola 《Contemporary educational psychology》1976,1(1):26-36

In two experiments, immediate feedback defined as feedback following the completion of a 40-item multiple-choice test and delayed feedback (received 48 hr later) were examined in a simulated classroom situation with college students. As defined, delayed feedback was not superior to immediate feedback, as would be predicted by the delayed retention effect. Also, feedback in the form of correct answer only was superior to correct answer plus distractors lending partial support to the frequency theory of recognition memory. In addition to not finding the delayed retention effect, an analysis of errors in experiment two did not support the interference—perseveration hypothesis as an explanation for the type of error committed following immediate feedback.  相似文献

Deliberate imagery practice: the reliability of using a retrospective recall methodology     

Cumming J  Hall C  Starkes JL 《Research quarterly for exercise and sport》2005,76(3):306-314

This study examined the reliability of a retrospective recall methodology for providing evidence of deliberate imagery practice. A secondary purpose was to determine which imagery activities constituted the sport-specific definition of deliberate practice (Starkes, Deakin, Allard, Hodges, & Hayes, 1996). Ninety-three Canadian athletes from one of three different competitive levels (regional, provincial, and national) completed the Deliberate Imagery Practice Recall Questionnaire, which was specifically designed for the present study. The athletes also completed a 1-week imagery diary to assess their use of 14 different imagery activities. The results of the study indicated that the athletes were able to reliably estimate their use of imagery over a short recall interval. Four imagery activities were also determined to fulfill the sport specific definition of deliberate practice.  相似文献

Vertical microbubble column–A photonic lab-on-chip for cultivation and online analysis of yeast cell cultures     

Stefanie Demming  Gena Peterat  Andreu Llobera  Hannah Schmolke  Alexander Bruns  Michael Kohlstedt  Ala‘aldeen Al-Halhouli  Claus-Peter Klages  Rainer Krull  Stephanus Büttgenbach 《Biomicrofluidics》2012,6(3)

This paper presents a vertically positioned microfluidic system made of poly(dimethylsiloxane) (PDMS) and glass, which can be applied as a microbubble column (μBC) for biotechnological screening in suspension. In this μBC, microbubbles are produced in a cultivation chamber through an integrated nozzle structure. Thus, homogeneous suspension of biomass is achieved in the cultivation chamber without requiring additional mixing elements. Moreover, blockage due to produced carbon dioxide by the microorganisms—a problem predominant in common, horizontally positioned microbioreactors (MBRs)—is avoided, as the gas bubbles are released by buoyancy at the upper part of the microsystem. The patterned PDMS layer is based on an optimized two-lithographic process. Since the naturally hydrophobic PDMS causes problems for the sufficient production of microbubbles, a method based on polyelectrolyte multilayers is applied in order to allow continuous hydrophilization of the already bonded PDMS-glass-system. The μBC comprises various microelements, including stabilization of temperature, control of continuous bubble formation, and two optical configurations for measurement of optical density with two different sensitivities. In addition, the simple and robust application and handling of the μBC is achieved via a custom-made modular plug-in adapter. To validate the scalability from laboratory scale to microscale, and thus to demonstrate the successful application of the μBC as a screening instrument, a batch cultivation of Saccharomyces cerevisiae is performed in the μBC and compared to shake flask cultivation. Monitoring of the biomass growth in the μBC with the integrated online analytics resulted in a specific growth rate of 0.32 h⁻¹, which is almost identical to the one achieved in the shake flask cultivation (0.31 h⁻¹). Therefore, the validity of the μBC as an alternative screening tool compared to other conventional laboratory scale systems in bioprocess development is proven. In addition, vertically positioned microbioreactors show high potential in comparison to conventional screening tools, since they allow for high density of integrated online analytics and therefore minimize time and cost for screening and guarantee improved control and analysis of cultivation parameters.  相似文献

Characteristics of child abuse in immigrant Korean families and correlates of placement decisions     

Chang J  Rhee S  Weaver D 《Child abuse & neglect》2006,30(8):881-891

OBJECTIVE: This study examined the characteristics and patterns of child abuse among immigrant Korean families in Los Angeles and critical variables that contribute to the type of placement made by the child protective services (CPS) system. METHOD: Data were obtained from reviewing and analyzing 170 active Korean case files maintained by the Asian Pacific Unit (APU) of the Los Angeles County Department of Children and Family Services (LAC-DCFS) during July through September, 2001. Logistic regression analysis was employed to examine the odds of children being kept in or removed from the home. RESULTS: Some of the major findings from this study include: (1) immigrant Korean families are more likely to be charged with physical abuse (49.4%) and less likely to be charged with neglect (20.6%) in comparison with all other groups in Los Angeles (13.2% and 27.1%, respectively); (2) the circumstance under which physical abuse occurred most frequently was corporal punishment used by Korean parents with an intention to discipline their children; and (3) the context under which emotional abuse occurred among the Korean families was likely to be children's witnessing domestic violence. In addition, the logistic regression showed that response status, referral source, living arrangement, victim's relationship to perpetrator, and chronicity of abuse were significant in predicting out-of-home placement. CONCLUSIONS: An analysis of Korean child abuse cases reported to child protective service revealed that culture and child rearing practices shaped the patterns of child maltreatment. A culturally sensitive approach is strongly suggested for effective child abuse prevention and intervention services with this group by CPS agencies.  相似文献
