Nitrogen is often released in pulses with different frequencies, and N supply pulses may affect growth, reproduction, and biomass allocation of plants. However, few studies have examined how N supply pulses affect intraspecific competition of clonal plants and whether such an effect depends on the N supply amount. We grew one (no competition) or 12 ramets (with intraspecific competition) of both an invasive clonal plant Alternanthera philoxeroides and its native congener Alternanthera sessilis in five different N treatments: control (no N addition), low/high amount with low/high frequencies (pulses). Nitrogen addition significantly increased the growth of both species, while intraspecific competition decreased it. Nitrogen addition significantly increased intraspecific competitive intensity of A. philoxeroides as measured by the log response ratio of growth traits, but did not affect that of A. sessilis. Despite the N supply amount, N pulses had little effect on the growth and thus intraspecific competition of the two species. Therefore, increasing N deposition may change population structure and dynamics and the invasion succession of A. philoxeroides, but changes in N pulses may not.

To win the competitive advantage in market, more and more companies began to apply HR mobile technology. The paper from 7 dimension to design questionnaire, which include "administrative, workforce management, talent management, business intelligent, service delivery, workforce optimization and social media", choose different companies and industries to explore the present situation of the domestic application of HR mobile technology. Compared to the successful experience of foreign enterprises put forward the development trend of domestic enterprises in the future: extensive use of cloud technology to improve the business intelligence and service delivery contribution to the enterprise, adopt the way of renting service to improve the proportion of small and medium-sized enterprise to use HR mobile technology, use of technology and industry standards such as measures to ensure the security of data, improve the user experience to promote employee self-service system widely used.
