The article examines historical and recent trends in the consumer publishing industry in order to make predictions about the
structure of that industry in 2020. The author anticipates the demise of the largest players in the industry, in both the
publishing and retail sectors. Their decline he attributes to a focus on supply chain management and a lack of attention to
innovation on the demand-side of the book business. In this respect he pays particular attention to studies of supply–demand
matching in the DVD business. 相似文献

This study evaluated the long-term impact of schoolwide positive behavioural interventions and supports (PBIS) on student academic achievement. In this quasi-experimental study, academic achievement data were collected over 9 years. The 21 elementary, middle, and high schools that achieved moderate to high fidelity to the Save & Civil Schools’ PBIS model were matched with 28 control schools to assess academic gains. There were 5 years of baseline data (no intervention in treatment schools) and 4 years of intervention data, including 1 year of maintenance. Results indicate that implementation of the PBIS programme was significantly associated with increased student academic achievement (p = .001) and that the rate of change for students’ academic achievement in treatment schools was greater than for students in control schools. This study suggests that PBIS programmes, such as Safe & Civil Schools’ Foundations, may complement other efforts to improve academic outcomes. 相似文献

ABSTRACTAiming at contributing to the preservation of black and white (B&W) film-based negatives held by Portuguese archives, four photographic collections from the first half of the twentieth century were selected for study. During the macro assessment of the collections the preservation condition and hues found in photographic negatives from the Elmano Cunha e Costa (ECC) were noticed, distinguishing this collection from the remaining ones. Additional attention was given considering that the ECC collection was formed in a colonial context in the 1930s, while the others were formed on the Portugal mainland. The ECC collection results from an ethnographic survey of Angolan tribes recorded with B&W film-based negatives. In this collection, sets of negatives with pink, lemon yellow, greenish, orange brownish, and red brownish hues were found. To identify the origin of such hues, the image layer was analysed by microscale energy-dispersive X-ray fluorescence (μ EDXRF) and scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDX). Additionally, to assess the base decay and its effect on the formation of hues, the plastic supports were characterized by Fourier transform infrared microscopy (μ FTIR). To complement the assessment of the film-base decay, pH was measured by using combined microelectrodes. The identification of mercury, iodine, chromium, and iron by μ EDXRF allowed correlation of the hues found in the negatives with chemical corrective treatments performed to improve the image quality. SEM-EDX confirmed those results and proved that the elements found were in the photographic emulsion layer. The results obtained are relevant since the hues identified may now be used as markers to indicate the technical work performed on colonial photography. Additionally, the visual and molecular assessment of the negatives’ supports (good to fair condition) allow proposing that the original storage conditions may have had a beneficial contribution to their present condition. 相似文献

High IQ is sufficient to explain the high achievements in math and science of the East Asian peoples
Richard Lynn 《Learning and individual differences》2010,20(6):567-568
It is argued that it is unnecessary to propose that Confucian values explain the high achievements in math and science of the North East Asian peoples, and that these can be satisfactorily and more parsimoniously be explained by their high IQs. 相似文献
