Wirksamkeit schulrelevanter Förderung in Kindertagesstätten     

Marcus Hasselhorn  Susanne Kuger 《Zeitschrift für Erziehungswissenschaft》2014,17(2):299-314

The present paper summarizes international and national research findings on the general and differential effectiveness of pedagogical work in early childhood education and care settings, evaluations of pilot projects on compensatory preschool education as well programs to support individual learning abilities. Based on these findings, the following conclusions are drawn: First, attending early childhood education and care settings at an early age (after the age of three) has a positive influence on the development of academic competences. Second, the effectiveness of these settings depends on the instructional quality, which could be considerably improved in Germany. Third, pilot projects on programs to support individual learning abilities could show that compensatory effects for disadvantaged groups of children exist, especially when they are interlinked with stimulating conditions in the family and at school. Fourth, effective training programs exist that can be implemented in early childhood education and care. However, a number of challenges need to be met before they can be successfully implemented.  相似文献   

To explore or to exploit? An empirical investigation of acquisitions by large incumbents     

Marcus Wagner 《Research Policy》2011,40(9):1217-1225

Innovation in high technology industries poses considerable challenges, frequently forcing firms to consider using acquisitions as a means of sourcing technology. This paper investigates such behaviour in a major high technology sector, namely the semiconductor industry. The paper focuses on differential effects of technology-related versus nontechnological acquisitions on exploratory and exploitative research and innovation. Most importantly, it confirms the important role of technology-related acquisitions for exploratory innovation.  相似文献

Tuition and U.S. private college characteristics: The hedonic approach     

Jon D. Harford  Richard D. Marcus 《Economics of Education Review》1986,5(4)

Tuition at private colleges in the United States for the academic year 1982–1983 were statistically very closely related to quality characteristics associated with those colleges. Reduced form hedonic regressions reveal the equilibrium marginal tuition revenue estimates for over twenty important measures of quality, including faculty-student ratios, library size, and the percentage of the faculty holding Ph.D. degrees. These findings show that private college tuition responds in economically sensible ways to changes in public tuition, and changes in the quantity and quality of the faculties, facilities, and student bodies at private colleges.  相似文献   

Change in the body temperature of healthy term infant over the first 72 hours of life     

李萌霞  孙革  NEUBAUER Henning 《浙江大学学报(A卷英文版)》2004,5(4):486-493

Objective: To determine the range of body temperature in a group of healthy Chinese term neonates over the first 72 hours of life and to assess the influence of body weight, gestational age and route of delivery. Method: All 200 consecutive cases of neonates delivered at our hospital from March to August 2001 were included in this retrospective study. Temperatures were measured immediately after delivery, after 30 minutes, 1 hour, 2 hours, 8 hours and 15 hours and on the 2nd and 3rd day. Axillary temperatures ranging from 36.5 oC to 37 oC were regarded as normal. No cases of maternal fever or systemic infection of the newborns were discovered. All infants were discharged in good general condition. Results: The mean rectal temperature at birth was 37.19 ℃. The lowest average temperature was reached at 1 hour after delivery (36.54 ℃) with a significant difference between natural delivery (36.48 ℃) and section (36.59 ℃) (P<0.05). Temperature subsequently rose to 36.70 ℃ at 8 hours and 36.78 ℃ at 15 hours (P<0.05). Hypothermia was seen in 51.8% and hypothermia in 42.5% of the patients. On the 3rd day after delivery, 96% of all temperatures were in the normal range. A significant relation was found between hypothermia and both low birth weight (P<0.001) and low gestational age (P<0.05). Conclusion: The reference range presently used did not include all physiological temperatures in the first 72 hours of life. Considering other factors, such as birth weight, route of delivery, gestational age and body temperature on the 2nd and 3rd day of life, may help to correctly assess the significance of temperatures beyond the reference range.  相似文献   

Advancing opportunities for children’s informal STEM learning transfer through parent–child narrative reflection     

Maria Marcus  Pirko Tõugu  Catherine A. Haden  David H. Uttal 《Child development》2021,92(5):e1075-e1084

This study examined whether families’ conversational reflections after a STEM (science, technology, engineering, and mathematics)-related experience in a museum promoted learning transfer. 63 children (M = 6.93 years; 30 girls; 57% White, 17.5% Latinx, 8% Asian, 5% African American, 9.5% mixed, 3% missing race/ethnicity) and their parents received an engineering demonstration, engaged in a building activity, and either recorded a photo-narrative reflection about their building experience or not at the museum. Thirty-six of these families completed a building activity with different materials weeks later at home, and the majority (77%) evidenced learning transfer of the building principle demonstrated at the museum. Those who participated in the photo-narrative reflection at the museum also showed learning transfer by talking more about STEM during the home building activity.  相似文献
