To cope with the rising labour cost and protect the country’s deteriorating environmental conditions, Chinese policy makers have recently made a series of policy changes to promote innovation and hence the development of a knowledge-based economy in the country in the coming decades. As a result, China’s R&D spending has expanded substantially. This paper contributes to the understanding of R&D...

Canada in the mid-1980s, we know virtually nothing about contraceptive use among Canadians during the 1990s.2 The 1995 General Social Survey (GSS-95) collected detailed information on contraceptive use, as well as fertility and union histories, from a nationally representative sample of Canadian women and men aged 15 and older. The main objective of this article is to use these data to update o...

We give a speciic product decomposition of the base-point path connected component of the triple loop space of the suspension of the projective plane.

China has experimented with two strategies of reform of its state-owned enterprises (SOE). One is diversification of SOEs’ ownership through introducing non-state sources of investment. Another is to improve the management of SOEs by granting SOEs’ managers autonomy and their employees profit incentives.

To compare the gene expression profiling between intestinal-type gastric cancer (IGC) and diffuse-type gastric cancer (DGC), cDNA microarray containing 7334 gene elements was performed on 12 paired IGC specimens/its' normal epithelial tissue and 11 paired DGC specimens/its' normal epithelial tissue. Twenty-seven genes were co-overexpressed in IGC and DGC. These overexpressed genes were related ...

The traditional warm-up (WU) used by athletes to prepare for a sprint track cycling event involves a general WU followed by a series of brief sprints lasting ≥ 50 min in total. A WU of this duration and intensity could cause significant fatigue and impair subsequent performance. The purpose of this research was to compare a traditional WU with an experimental WU and examine the consequences of ...
