Social entrepreneurship: Creating new business models to serve the poor

The term bsocial entrepreneurshipQ (SE) is used to refer to the rapidly growing number of organizations that have created models for efficiently catering to basic human needs that existing markets and institutions have failed to satisfy. Social entrepreneurship combines the resourcefulness of traditional entrepreneurship with a mission to change society. One social entrepreneur, Ibrahim Abouleish, recently received the bAlternative Nobel PrizeQ for his Sekem initiative; in 2004, e-Bay founder Jeff Skoll donated 4.4 million pounds to set up a social entrepreneurship research center; and many social entrepreneurs have mingled with their business counterparts at the World Economic Forum in Davos. Social entrepreneurship offers insights that may stimulate ideas for more socially acceptable and sustainable business strategies and organizational forms. Because it contributes directly to internationally recognized sustainable development (SD) goals, social entrepreneurship may also encourage established corporations to take on greater social responsibility.

Green marketing and its impact on supply chain management in industrial markets

Green marketing and green supply chain have been drawing the attention of both academics and practitioners in the recent decade. However, no holistic framework has been developed on how to build green industrial brands and industrial corporate brands. Whether or not sustainable/green supply chains can be integrated with green industrial marketing in building greener organizations and industrial brands is still unclear. In addition, little is known on the factors on green new industrial product development or how green new industrial products are adopted by organizations. Furthermore, we know little of whether and how green supply chain enables green new industrial product development. This special issue aims at reflecting the most recent advances on green industrial marketing, green/sustainable supply chains and their interplay in green industrial branding, and to explore future research directions. The guest editors hope that the solicited papers can provide insightson the impacts of sustainable or green supply chains on marketing theory in industrial and business-to-businessmarkets.
Recycling of waste tire rubber in asphalt and portland cement concrete[taliem.ir]

Recycling of waste tire rubber in asphalt and portland cement concrete: An overview

Waste tires pose significant health and environmental concerns if not recycled and/or discarded properly. Over the years, recycling waste tires into civil engineering applications, especially into asphalt paving mixtures and portland cement concrete, has been gaining more and more interests. This review summarizes the recent advances in the use of waste tire rubber in asphalt and portland cement concrete. The use of crumb rubber in asphalt paving mixture has long been proven successful due to good compatibility and interaction between rubber particles and asphalt binder, leading to various improved properties and performance of asphalt mixtures. The rubberized asphalt mixtures also have shown good compatibility with two widely used sustainability technologies in asphalt paving industry – reclaimed asphalt pavement (RAP) and warm-mix asphalt (WMA). In comparison with its use in asphalt paving mixtures, recycling of waste rubber in Portland cement concrete has not been so successful due to two factors: (1) incompatibility in chemical property between rubber and cement paste and (2) the significant difference in stiffness resulting in stress concentrations. Various methods have been proposed to overcome the barriers to improve the performance of rubberized portland cement concrete, some of which have shown to be promising.

Water is an economic good: How to use prices to promote equity, efficiency, and sustainability

In 1992 the Dublin Water Principles claimed ‘‘water as an economic good’’ for the first time in a UN setting. But water has been recognized as an economic good for many centuries before 1992. Throughout Europe and the early United States private water supply companies thrived in a wide variety ofsettings. The ‘‘sanitary revolution’’ ofthe 19th century saw the demand for public ownership and management ofmost ofthese companies in the name ofpublic health. This, of course, did not obviate the need for water to be treated as an economic good, but a heavy emphasis on the public-good nature ofwater and its disposal led to the development ofheavily subsidized public systems. With the exception ofFrance, this was the path followed in most countries around the world. In the late 1980s, however, the World Bank and other multilateral and bilateral institutions discovered the virtues of‘‘privatization’’ in the provision ofpublic services and with privatization all of the attendant problems of setting tariffs and prices.
