效率再造--报业集团做强之策略分析

我国报业集团化发展至今已经9个年头,报业集团的数量也已增加到目前的41家。由于报业的集团化之路缺乏必要的企业化铺垫,都或多或少地受到政治力量的推动,因此,在一定时段内各子报子刊会存在貌合神离、各自为战的现象,很可能导致“内耗”,造成“规模不经济”。因此,只有将子报子刊的资源有效整合,才能弥补报业集团浮躁发展带来的危险,才能真正实现经济学意义上的“规模经济”。     

A new approach to increase the attainable rice yield in intensive irrigated rice systems of Zhejiang province, China

A new site-specific nutrient management approach was developed to break the apparent attainable yield barrier of 6 t·ha⁻¹ in the double rice cropping system of Zhejiang. On-farm experiments involving 21 rice-growing farmer families and NPK long-term experiments commenced in 1997 in the central part of Zhejiang Province to assess the status of soil fertility and productivity under intensive rice-rice cropping. A new site-specific nutrient management (SSNM) approach has been developed for this studied area. Field-specific fertilizer recommendations are calculated considering indigenous nutrient supply, reasonable grain yield targets and corresponding nutrient demand, nutrient balance and nutrient use efficiency, as well as socio-economic factors. The agronomic performance of SSNM was tested against the farmer's fertilizer practice (FFP) in four 1998–1999 cropping seasons. Across seasons and years, SSNM consistently increased plant nutrient uptake, grain yield and profit by about 10%–15% compared to the FFP. Yield levels of 7.5 t·ha⁻¹ or more seem achievable and sustainable through introduction of SSNM and improved extension services in Zhejiang Province. Project supported by the International Fertilizer Industry Association(IFA), the Potash and Phosphate Institute, Canada (PPIC), and International Potash Institute(IPI).     

房地产业的宏观调控研究

近年来我国房地产业出现了快速发展的过热现象,其原因复杂。2004年中央开始有针对性地对房地产行业进行宏观调控,但过去的和现有的政策只具有明显的短期效应。因此,各级政府必须从房地产行业目前的机制与现存的问题出发,建立与市场经济相适应的房地产业宏观调控的长效机制,真正使房地产业长期稳定健康的发展。     

Challenging from the margins into the mainstream—improving renal services in a collaborative and entrepreneurial spirit

Can the development, both clinical and managerial, of practitioners involved in healthcare be enriched by connecting action learning principles and practice with research on ‘tempered radicals’? Might such connection also assist the efforts of patients and their advocates to create more holistic approaches to patient care? This paper explores these questions with reference to a UK Department of Health project to improve renal services. The prime focus is the experience of a set of set advisers who ‘held the ring’ on the project, supporting the work of the sets and attempting to make sense of the emerging learning.     

非言语交际在儿童英语教学中的应用(英文)

Non-verbal communication is a necessary and an important approach when we communicate with others. Teaching is also a kind of communications between teachers and students. So, non-verbal behaviors that teachers adopt during class are very useful, especially to teach pupils English. This paper is based on this and discusses different non-verbal behaviors in the pupils’ English class.

Searching high gray scale FPD scanning matrix based on PSO

With the increase of gray scale and flat panel display (FPD) size, subspace bitwise scanning strategy can be replaced traditional scanning method to cut down frame frequency. However, the direct searching strategy (DSS) becomes unfeasible to obtain corresponding high gray scale scanning matrix. Thus, particle swarm optimization (PSO) is introduced to accelerate searching for high gray scale weights scanning matrix (WSM) with its parallelism and global optimization feature. Finally a WSM of 256 gray scales is found out successfully with Matlab, which both gray linearity and scanning efficiency are satisfied.
