This paper presents a simple profitability-based decision model to show how synergistic gains generated by the joint adoption of complementary innovations may influence the firm's adoption decision. For this purpose a weighted index of intra-firm diffusion is built to investigate empirically the drivers of the intensity of joint use of a set of complementary innovations. The findings indicate that establishment size, ownership structure and product market concentration are important determinants of the intensity of use. Interestingly, the factors that affect the extent of use of technological innovations do also affect that of clusters of management practices. However, they can explain only part of the heterogeneity of the benefits from joint use. 相似文献

The aim of the present research is to assess the developmental pattern of the metacognitive knowledge of attention in Italian primary school students. Data were collected from 95 pupils divided into two age groups: the first (6–8 years) and second primary school cycles (8–10 years). The children were asked to perform two specific thematic drawings on attention vs inattention in the school context. The drawings were coded on the basis of the Children’s Awareness of Attention through Drawing, consisting of five scales which explore the behavioural, pragmatic, cognitive, emotional and social awareness of attention. The analysis of the thematic drawings reveals that from the early years of primary school, children are aware of some components of attention: behavioural awareness, pragmatic awareness and social awareness. Other components are instead acquired as of the age of eight. 相似文献

Using primarily the example of Computerised Numerically Controlled Machine Tools (CNC) in the UK metalworking and engineering industry, it is shown that, even many years after the date of first use of a new technology, although the larger proportion of firms may be using that technology, because the extent of intra-firm diffusion is limited, the proportion of total industry output produced on that technology may be quite small. Using backward projection techniques it is further shown that intra-firm diffusion tends to lag behind inter-firm diffusion over the whole of the diffusion process and inter-firm diffusion patterns and extent may thus be poor indicators of overall diffusion. Although intra-firm diffusion is therefore crucial to the understanding of overall diffusion patterns the existing literature relating to it has severe limitations and there are no associated policy results. It is argued that much greater emphasis should be placed on intra-firm issues in future diffusion research. It is also suggested that discussions of intra-firm policy could usefully proceed within the context of already established general diffusion policy principles. 相似文献
