Economic Potential of Biomass Based Fuels for Greenhouse Gas Emission Mitigation

Use of biofuels diminishes fossil fuelcombustion thereby also reducing net greenhousegas emissions. However, subsidies are neededto make agricultural biofuel productioneconomically feasible. To explore the economicpotential of biofuels in a greenhouse gasmitigation market, we incorporate data onproduction and biofuel processing for thedesignated energy crops switchgrass, hybridpoplar, and willow in an U.S. AgriculturalSector Model along with data on traditionalcrop-livestock production and processing, andafforestation of cropland. Net emissioncoefficients on all included agriculturalpractices are estimated through crop growthsimulation models or taken from the literature. Potential emission mitigation policies ormarkets are simulated via hypothetical carbonprices. At each carbon price level, theAgricultural Sector Model computes the newmarket equilibrium, revealing agriculturalcommodity prices, regionally specificproduction, input use, and welfare levels,environmental impacts, and adoption ofalternative management practices such asbiofuel production. Results indicate no rolefor biofuels below carbon prices of $40 perton of carbon equivalent. At these incentivelevels, emission reductions via reduced soiltillage and afforestation are more costefficient. For carbon prices above $70,biofuels dominate all other agriculturalmitigation strategies.     

Impacts of an EC carbon/energy tax and deregulating thermal power supply on CO2, SO2 and NOx emissions

Emission of CO₂, SO₂ and NO_x are all closely linked to the burning of fossil fuels. Here we report on simulations done by linking a Sectoral European Energy Model (SEEM), covering energy demand in nine Western European countries, with the emission-transport-deposition model RAINS developed by IIASA. The study analyses emissions of CO₂, SO₂ and NO_x, deposition of sulphur and nitrogen and the extent of areas where the critical load for sulphur is exceeded in year 2000 under four different energy scenarios. Two different sets of future behavioural patterns for the thermal electric power production sector are considered. In one regime, called the plan-efficient regime, the sector is assumed to follow official plans with regard to investment in new capacity. In the other regime, called the cost-efficient regime, the thermal power sector is assumed to behave in a cost minimizing manner. The effects of the proposed EC carbon/energy tax are studied under both regimes, giving rise to altogether four scenarios.In both regimes the effect of the EC tax is to reduce emissions by between 6 and 10 per cent in year 2000 relative to the scenarios without the tax. A change of regime, from the regulated, plan-efficient regime to the market-based, cost-efficient regime, will, by itself, reduce emissions of CO₂ and NO_x by approximately 3 per cent, while SO₂ emissions are reduced by 13 per cent. The EC tax will reduce sulphur deposition by more than 5 per cent in the nine model countries under the plan-efficient regime. A change of regime further reduces the total deposition by 9 per cent. The area where depositions exceed the critical load is reduced by approximately 6 per cent in year 2000 by the tax in both regimes. Changing from the plan-efficient to the cost-efficient regime has a similar impact.Although the emission reductions due to the EC tax may seem modest, they are shown to have a sizeable effect on the technological abatement costs of reaching targets like those prescribed in the Sofia protocol on the stabilisation of NO_x emissions, and the Helsinki protocol on SO₂ emission reductions. This is part of what can be considered to be secondary benefits of the EC carbon/energy tax.

上市公司控制权争夺的动机及其特征

本文结合国内外研究成果以及我国当前的市场环境,对可能成为控制权争夺目标的公司会具备什么样的财务特征、股权结构以及公司治理进行了分析,以寻找上市公司控制权争夺的真正动机和目的.我们研究发现:上市公司经营业绩越差,债务比率越高,当年具有增发或配股资格,产权的可转让性越低,产权性质为国有企业和终极控制人为国有企业或政府机构时,其控制权被争夺的可能性也越高.     

会计价值机制论

本文认为,市场和企业是组织经济活动的形式,也是组织价值信息传递和价值激励的系统。市场价格机制是在长期市场供求关系作用下而形成的,而会计价值机制是随着企业的发展不断演化,在企业目标引导下组织价值信息传递和价值信息激励,以促成企业目标实现。企业替代市场或取得竞争优势,都是基于相同的原因和两种机制作用的结果,即是通过企业提供的产品或服务的成本低于市场价格而实现的。     

关于财政总预算会计制度改革的探讨

20世纪90年代,我国预算会计改革已取得重大成就,初步建立起适应社会主义市场经济需要的预算会计体系。近年来,随着我国以预算管理为中心的财政制度的不断深化,预算会计制度的诸多问题和局限性也逐渐产生和显现出来,面临着如何作进一步的改革问题。本文通过分析现行财政总预算会计制度的基本特点,探讨财政总预算会计制度存在的问题,并为进一步改进财政总预算会计制度的核算和管理提出一些看法。     

A substitution orbit model of competitive innovations

Successful innovation and diffusion of technology can be attributed to the identification of the orbit of emerging new technologies that complement or substitute for existing technologies. This dynamism resembles the co-evolution process in an ecosystem. In an ecosystem, in order to maintain sustainable development, the complex interplay between competition and cooperation, typically observed in predator-prey systems, create a sophisticated balance. Given that an ecosystem can be used as a masterpiece system, this sophisticated balance can provide suggestive ideas for identifying an optimal orbit of competitive innovations with complement or substitution dynamism.Prompted by such a sophisticated balance in an ecosystem, this paper analyzes the optimal orbit of competitive innovations and, on the basis of an application of Lotka-Volterra equations, it reviews substitution orbits of Japan's monochrome to color TV system, fixed telephones to cellular telephones, cellular telephones to mobile Internet access service, and analog to digital TV broadcasting. On the basis of substitution orbits analyses, it attempts to extract suggestions supportive to identifying an optimal policy option in a complex orbit leading to expected orbit.Key findings include policy options that are effective in controlling parameters for Lotka-Volterra equations leading to expected orbit.     

城市化释义

城市是人类社会经济发展的必然结果、现代文明的标志及创新的载体,是政治、经济、文化、教育和信息中心,具有集聚、规模和辐射等功能效应。2000余年来,城市内涵随历史发展不断丰富。城市化一词的出现至今也有百余年历史,不同学科对城市化理解不同。其实质是一个以人为中心、受众多因素影响的复杂多变的软硬件系统化过程,是从传统向现代全面转型和变迁的过程。不仅是农业人口向非农、并向城镇的聚集,而且是城镇在空间数量、区域规模、功能作用诸方面的扩大,以及城市经济关系、居民生活方式改变的过程。城市化与城镇化、农村城市化、农村城镇化及城乡一体化等相关新概念有所区别。从区位论、结构论、人口迁移论、非均衡增长论到生态学派论,从梯度推移、增长极与地域生产综合论到产业集群论的演进,体现了城市化发展理论的深化。不同学者时城市化“推拉”动力机制认识不同。不同阶段和同一发展阶段的不同地区,动力机制相异。中国现阶段城市化动力机制包括：农业工业化推动、比较利益驱动、农业刺余贡献和制度变迁促进等。     

Comparing the impact of management support on police officers’ perceptions of discretionary power and engagement: Australia,USA and Malta

Abstract

This paper uses Social Exchange Theory as a lens for comparing the impact of management support upon police perceptions of discretionary power and employee engagement, across three countries. A survey-based, self-report process collected data from 193 police officers in Australia, 588 from the USA, and 249 from Malta. Structural equation modelling was used to analyse the data. The findings suggest a significantly different management support context across the three countries, as well as significantly different perceptions of discretionary power. Across the three countries, police perceived relatively poor satisfaction with organizational management support and only some engagement levels. However, USA police perceived significantly more discretionary power than the other country samples. These findings provide greater clarity about the link between management support, discretionary power and engagement for the police officers. Since employee engagement likely affects policing outcomes, the findings suggest that poor management support of police officers could negatively affect the provided service. Potential strategies to enhance police engagement include (a) training police managers about how to manage so as to promote greater engagement, and (b) modifying police managers’ performance indicators in line with achieving better police engagement.
