优化分配方式 提高资金环境绩效

十一五期间中央环境保护专项资金下达近91亿元,为我国环境污染防治和监管基础能力建设提供了强有力的资金保障。随着财政资金使用改革的不断深入,财政部和环保部对中央环境保护专项资金的管理已从过去以评审为中心转变为以绩效为中心,无论在资金投向、分配方式、过程管理、绩效评估等方面都紧密围绕环境绩效这一中心开展。本文在对十一五期间中央环境保护专项资金资金分配总体情况总结归纳的基础上,分析了资金分配方式制约绩效发挥的主要问题,以改革创新资金分配方式、提高环境绩效为目的,对中央统筹法、项目申报法、因素分配法等三种分配方式提出了若干改革优化的建议。

Inclusive education for children with disabilities in a refugee camp

Children in refugee camps, and particularly those with disabilities, face unique challenges in accessing education and are at high risk of being marginalised. Best practices suggest that main-streaming is the optimal strategy for serving students with disabilities. This study examines the extent to which mainstreaming in a refugee camp helps to promote children's prosocial behaviours, taking into account their emotional and behavioural problems. In Kakuma Refugee Camp, Kenya, researchers collected data from the parents of children currently enrolled in special needs education centres (n=65) and from those formerly enrolled at these facilities who transitioned to mainstream classrooms (n=81). Children in mainstream schools functioned better in terms of prosocial behaviours, but this relationship disappeared when factoring in children's emotional and behavioural difficulties. In the context of a refugee camp, mainstreaming alone is not likely to help children's psychosocial and educational functioning, which requires dedicated supports, appropriate facilities and infrastructure, and a dual focus on disability-specific and disability-inclusive initiatives.     

The Challenge of Civil-military Relations in International Peace Operations

The relationship between military and civilian humanitarian organisations has developed in an increasingly integrative way. Military initiatives to institutionalise the relationship, since the interventions in Somalia and the Balkans, entail a dilution of humanitarian independence as was manifested in practice in Kosovo. Further, the state-centric foundations of military intervention run counter to the potential for humanitarian organisations to foster a cosmopolitan ethos that would not only preserve humanitarian principles but also contest statist assumptions about conflict, development and power.     

Thermodynamics,economics and systems thinking: What role for air capture of CO2?

Air capture has recently been advanced by several parties as a solution to the problem of constraining – and ultimately reducing – atmospheric CO₂ in response to climate change. However, there are significant barriers pertaining to scale, energy needs and cost, which will hugely challenge the effectiveness and practicality of air capture. This paper examines the thermodynamics, energetics and economics and politics of air capture. These compare unfavourably with alternative approaches to atmospheric greenhouse gas reduction. An analysis is made of the energy cost of the one favoured DAC technology for which experimental results are available in the open literature – temperature/vacuum swing adsorption, and of one point source capture technology – oxyfiring of refinery FCCUs. We also examine the engineering effort required to implement atmospheric capture on a scale at which it could significantly reduce atmospheric levels of CO₂; and questions are addressed regarding its practicability and appropriateness. The analysis demonstrates that air capture remains at best a peripheral activity, at worst a distraction, until point sources of greenhouse gas emissions such as power stations, industrial flue gases, shale gas wellheads, anaerobic digestion plants and landfill sites have been completely decarbonised. When these and so many other unaddressed factors are affecting our global climate, the pursuit air capture, the ultimate “end-of-pipe” solution, is inappropriate.     

Green management practices and firm performance: A case of container terminal operations

This study aims to investigate the elements of green management practices (GMP) and its association with firm performance. A GMP model that consists of the key elements of GMP is proposed and firm performance indicators are formulated to provide a foundation for the adoption of GMP. Hutchison Port Holding (HPH) is selected as the case to illustrate the application of the proposed GMP model in a real-life situation. The findings suggest that GMP consists of the following elements: (1) cooperation with supply chain partners, (2) environmentally friendly operation, and (3) internal management support. Findings of this study also indicate a positive relationship exists between the adoption of GMP and firm performance. Hence, operators in the container terminal industry should strive to adopt GMP in order to achieve good firm performance including improvement in terminal throughput, profitability, and efficient and cost-effective operation.

Mixed methodology to analyze the relationship between maturity of environmental management and the adoption of green supply chain management in Brazil

The aim of this research is to verify the relationship between the maturity levels of environmental management and the adoption of green supply chain management (GSCM) practices by electro-electronic companies in Brazil. In this work a two-phase research was conducted, with one quantitative and the other qualitative. The quantitative phase aimed to test whether a relationship between the maturity levels of environmental management and GSCM exists, while the qualitative phase tried to detail the characteristics of this relationship. The quantitative phase was conducted through a survey with 100 Brazilian electro-electronic companies and the collected data were processed using Structural Equation Modeling. For the qualitative phase, a multiple case study was conducted with three companies located in Brazil. The results indicate that: (1) The main hypothesis was confirmed and considered statistically valid, indicating that, indeed, the maturity level of environmental management influences the adoption of GSCM practices; (2) a coevolution tends to occur between the environmental maturity and the GSCM practices; that is, the more developed is the company's environmental management, more complex GSCM practices are adopted; and (3) the GSCM internal practices tend to present a greater relative adoption than the external practices; these external practices of GSCM tend to be adopted when the company is inserted in a higher environmental stage and/or operates under a scenario of stronger normative environmental pressure. By the way, this is the first research mixing survey and case studies on GSCM in Brazil.
