This article examines how shortened magazine supply duration of magazines effects newsstand sales. Based on a quasi-experimental design, panel data are gathered from a total of 33 newsstand vendors in cooperation with a magazine wholesaler in southwestern Germany. As results show, a shortening in magazines' supply duration does not lead to a significant decrease in a newsstand vendor's or a wholesaler's overall revenues. Furthermore, diverse categories of magazines are affected differently by a shortening of supply durations. 相似文献

Several studies have assessed whether funding of disease specific research is in line with their burden. The authors of these studies concluded that the burden of a disease was a good predictor for its associated research funding. However, previous analyses did not take into account diseases that mainly affect people living in low income regions, i.e. so-called diseases of poverty. Moreover, the analyses were only performed for the burden diseases cause in high income countries. We investigated whether the conclusions about the relationship between burden and funding still holds when (1) including diseases of poverty and (2) accounting for the burden of diseases in low income countries. We found that the relationship between the burden and the level of diseases specific funding decreases for people living in low income countries. We find the best predictor for the level of funding to be the mortality in high income countries. In contrast to previous studies, we were able to include more diseases into our analyses (74). This enabled us to discover differences in funding levels between and within groups of diseases. we found that research on cancers was over funded with respect to the associated burden. In contrast, diseases of poverty systematically receive less funding than would be expected based on their burden. Other groups of diseases (cardiovascular diseases and mental illnesses) contained both over and under funded diseases. 相似文献

The problems that educational research are supposed to solve have been poorly analyzed and the basic phenomena that we are trying to understand have not been clearly described. Educational experimenters often resemble Leerlaufreaktionen in lower animals, i.e., complex, highly integrated activities that take place despite the absence of an appropriate environmental occasion. We have tended to forget the practical origins of science and have allowed ourselves to be dominated by overly abstract ideas that betray our goals. Experimenters require tangible events to think and wonder about in order to improve their intuitions and in order to generate and test ideas that will deepen our understanding of nature and make a real difference in the practical world. Better observations of what actually goes on in instructional situations are therefore needed and more detailed records of teaching and learning must be kept. An instructional record‐keeping system called a course memory is described. 相似文献

Over 100 years of learning and cognition research have had only modest cumulative impact on teaching, while many other practical
domains such as agriculture have shown a steady growth in widely accepted, research-informed practices. Several reasons have
been advanced for the painfully slow adoption of science-based instructional procedures. One important but not widely recognized
obstacle is proposed here, namely, that the aims of fundamental learning and teaching research do not mesh well with the practical
logic of schools. Basic learning research tends to focus on efficiency, i.e., how much can be learned from a given amount
of effort or time but teaching efficiency is not a strong concern for schools. This is because they generally focus on global
year-end results while the efforts required at the tactical lesson level are only loosely monitored. School administrators
tend to reckon costs in terms of the number of engaged teachers and not in the difficulty of each teacher’s job. For these
reasons, schools can be expected to have only nominal interests in science-informed, close management of tactical pedagogic
units. Psychological work on labor saving possibilities, such as research-based instructive products, is more likely to be
readily welcomed than improvements in lesson efficiency, especially in middle and high schools. Instructional enterprises
in which the cost and the benefits of instruction are borne by the same agency, such as industrial training, are the most
likely consumers of efficiency-related basic cognitive research.
