Market orientation, job satisfaction, product quality, and firm performance: Evidence from China

Abstract: This article examines the processes by which market orientation (MO) affects performance using a cross-level approach. The results of a survey of 2,754 employees from 180 firms in China show that organization-level MO culture leads to unit-level MO behavior, which improves employee-level job satisfaction and then product quality, which in turn fosters organizational performance. In particular, MO behavior fully mediates the effects of MO culture on employee satisfaction, product quality, and organizational performance. Leadership quality strengthens the effect of MO culture on unit-level MO behavior. Moreover, MO behavior enhances firm performance indirectly through employee job satisfaction and product quality.

A new insight into land use classification based on aggregated mobile phone data

Abstract: Land-use classification is essential for urban planning. Urban land-use types can be differentiated either by their physical characteristics (such as reflectivity and texture) or social functions. Remote sensing techniques have been recognized as a vital method for urban land-use classification because of their ability to capture the physical characteristics of land use. Although significant progress has been achieved in remote sensing methods designed for urban land-use classification, most techniques focus on physical characteristics, whereas knowledge of social functions is not adequately used. Owing to the wide usage of mobile phones, the activities of residents, which can be retrieved from the mobile phone data, can be determined in order to indicate the social function of land use. This could bring about the opportunity to derive land-use information from mobile phone data. To verify the application of this new data source to urban land-use classification, we first construct a vector of aggregated m...

Ultrafast growth of single-crystal graphene assisted by a continuous oxygen supply

Abstract: Single-crystal graphene can be grown on a copper foil at a rate of 60 μm s-1 by using an adjacent oxide substrate that continuously supplies oxygen to the surface of the copper catalyst. Graphene has a range of unique physical properties1,2 and could be of use in the development of a variety of electronic, photonic and photovoltaic devices3,4,5. For most applications, large-area high-quality graphene films are required and chemical vapour deposition (CVD) synthesis of graphene on copper surfaces has been of particular interest due to its simplicity and cost effectiveness6,7,8,9,10,11,12,13,14,15. However, the rates of growth for graphene by CVD on copper are less than 0.4 μm s–1, and therefore the synthesis of large, single-crystal graphene domains takes at least a few hours. Here, we show that single-crystal graphene can be grown on copper foils with a growth rate of 60 μm s–1. Our high growth rate is achieved by placing the copper foil above an oxide substrate with a gap of ∼15 μm between them. The oxide substrate provides a continuous supply of oxygen to the surface of the copper catalyst during the CVD growth, which significantly lowers the energy barrier to the decomposition of the carbon feedstock and increases the growth rate. With this approach, we are able to grow single-crystal graphene domains with a lateral size of 0.3 mm in just 5 s.
