Idiosyncratic deals in contemporary organizations: A qualitative and meta‐analytical review

Idiosyncratic deals (i‐deals) research focuses on the emergence of customized work arrangements employees negotiate with their employers. This article provides a critical review and synthesis of i‐deals research, combining a qualitative review of i‐deals theory and research with a supplementary meta‐analysis of 23 empirical studies (k = 27 samples, N = 8110 individuals). The qualitative review examines the conceptualization and measurement of i‐deals and identifies patterns and gaps in i‐deals research, while the quantitative meta‐analysis tests the moderating effect of societal cultures on the predictors and consequences of ideals investigated to date. In each section, attention is given to strengths and weaknesses of current approaches to i‐deals theory and research. Future research directions are identified with particular emphasis on the largely unexamined role of i‐deals from a multilevel perspective. Copyright © 2014 John Wiley & Sons, Ltd.     

CIBR污泥吸附有机物机理及应用

通过吸附实验考察连续流间歇生物反应器(CIBR)中污泥对有机物的吸附效果及吸附类型,分析好氧、缺氧和厌氧环境对污泥吸附有机物能力的影响,进而探讨污泥的吸附能力在CIBR实现有机物高效去除中的作用.实验结果表明,污泥对有机物的吸附主要是物理吸附.好氧/缺氧/厌氧环境对活性污泥及其灭活污泥吸附有机物能力影响不大,各环境下平均吸附率分别达到54.09％和48.62％.污泥良好的吸附能力及其先吸附后生物降解的特性,保证了CIBR混合液中COD值始终低于30 mg/L.     

How China’s current energy pricing mechanisms will impact its marginal carbon abatement costs?

Economic and social costs and benefits are critical factors affecting greenhouse gas abatement activities. Recognizing that energy prices are one of the most important factors influencing abatement costs, this study improved the basic China Energy and Environmental Policy Analysis (CEEPA) model by introducing a current energy pricing mechanism for China. The improved model was applied to generate marginal abatement cost (MAC) curves for China including the current energy pricing mechanism and to analyze MACs for the whole country and main abatement sectors in China under different energy pricing mechanisms. The results show that China MACs are sensitive to pricing mechanisms for electricity and refined oil. Ignoring the current regulation of these prices will lead to MAC underestimation, and price liberalization of these two energy sources could lead to a decrease in China MACs. Under a 50 % emission reduction target, if the electricity price regulation is ignored, the China MAC is underestimated by almost 16 %. Energy pricing reforms will lead to variations in sectoral abatement costs and overall abatement potential, and these impacts are projected to be large in the electricity sector. Under a 50 % reduction target, if the electricity price regulation is liberalized, MAC for the electricity sector nearly will decrease 50 %.     

Process analysis of characteristics of the boundary layer during a heavy haze pollution episode in an inland megacity, China

Ground observation data from 8 meteorological stations in Xi'an, air mass concentration data from 13 environmental quality monitoring sites in Xi'an, as well as radiosonde observation and wind profile radar data, were used in this study. Thereby, the process, causes and boundary layer meteorological characteristics of a heavy haze episode occurring from 16 to 25 December 2013 in Xi'an were analyzed. Principal component analysis showed that this haze pollution was mainly caused by the high-intensity emission and formation of gaseous pollutants (NO₂, CO and SO₂) and atmospheric particles (PM_2.5 (fine particles) and PM₁₀ (respirable suspended particle). The second cause was the relative humidity and continuous low temperature. The third cause was the allocation of the surface pressure field. The presence of a near-surface temperature inversion at the boundary layer formed favorable stratification conditions for the formation and maintenance of heavy haze pollution. The persistent thick haze layer weakened the solar radiation. Meanwhile, a warming effect in the urban canopy layer and in the transition zone from the urban friction sublayer to the urban canopy was indicated. All these conditions facilitated the maintenance and reinforcement of temperature inversion. The stable atmospheric stratification finally acted on the wind field in the boundary layer, and further weakened the exchange capacity of vertical turbulence. The superposition of a wind field with the horizontal gentle wind induced the typical air stagnation and finally caused the deterioration of air quality during this haze event.

江安河武侯区段水质改善的环境经济效益研究

根据成都市江安河武侯区段2010年11月-2011年3月的水质监测数据,结合中国地表水环境质量标准(GB3838-2002)和四川省实际确定水体中各污染物因子的本底浓度对该区段污水处理环境效益进行了分析。首先通过污染经济损失模型计算COD、BOD5、NH3-N、TP、SS和硫化物对水经济价值的损失率,然后在讨论COD、NH3-N、TP和硫化物减排情况的基础上计算了各种污染指标减排至达标后所产生的环境经济效益。研究结果表明,江安河武侯区段水体污染的综合污染损失率高达99.99%,如果各种污染物减排达标至IV类标准产生的环境经济效益14 912万元人民币/a,而减排达标至III类标准产生的环境经济效益更是高达15 786万元人民币/a。
