Under the circumstances of low-carbon economy, the theoretical applications of the green supply chain management of steel and iron manufacture are to reform and innovate the present manufacturing process, enhance the controlling and reclaiming, and recycling using of the waste steel and iron, steel slag, and dust emissions, establish the green supply chain structure oriented to the cycle of “re...

The paper examines the validity of two indices of sustainability: family planning programme sustainability (PSI) and outcome sustainability (OSI) developed by Tsui and Knight (1997) by applying their original method to recent data. The indices succeed in identifying the directional path of programme and outcome sustainability. Close correlations are found between PSI and OSI predicted values an...

A primitive economic model with classical population theory is constructed in order to examine the greenhouse effect on the sustainability of human population as well as the environmental tax when the sustainability is in danger. The conclusion of this paper is that when the negative effect is small, the tax can guarantee the sustainability, where the effective tax rate interval for the sustain...

A key problem in the manufacture of highlycustomized products is the synthesis of controllers able to manufacture any instance of a given product type on a given production or assembly line. In this paper, we extend classical AI behavior composition to manufacturing settings. We first introduce a novel solution concept for manufacturing composition, target production processes, that are able to...

A recent proposal that leatherworkers might face a reproductive hazard was tested using data from a large survey in Montreal of occupational factors in pregnancy. The outcome ofpregnancy in almost 400 women employed in the manufacture of leather products, some 6000 employed in other types of manufacture, and nearly 50 000 employed but not in manufacture were compared. There was little differenc...

In the past few decades, there have been extensive efforts on measuring sustainability. One example is the development of assessment tools based on sustainability indicators. Several individuals and organisations have suggested various indices for assessing sustainability. This paper focuses on the review of water sustainability assessment using the indicator-based approach. It discusses major ...

Almost all cities in the United States have initiated efforts to become more sustainable. Theoretically, sustainability encompasses social equity, as well as ecological and economic systems. In practice, many cities are unsure about the role of equity in sustainability planning. With greater knowledge of how urban sustainability initiatives affect social equity, public officials will better be ...
