Life cycle assessment of power generation alternatives for a stand-alone mobile house

This paper presents comparative life cycle assessment of nine different hybrid power generation solutions that meet the energy demand of a prototypical mobile home. In these nine solutions, photovoltaic panels and a wind turbine are used as the main energy source. Fuel cell and diesel generator are utilized as backup systems. Batteries, compressed H-2, and H-2 in metal hydrides are employed as backup energy storage. The findings of the study shows that renewable energy sources, although they are carbon-free, are not as environmentally friendly as may generally be thought. The comparative findings of this study indicate that a hybrid system with a wind turbine as a main power source and a diesel engine as backup power system is the most environmentally sound solution among the alternatives.</p

Political orientations, ideological selfcategorizations, party preferences, and moral foundations of young Turkish voters

Yılmaz, Onurcan (Dogus Author) -- Bahçekapılı, Hasan Galip (Dogus Author)Political ideology is often characterized along a liberal–conservative continuum in the United States and the left–right continuum in Europe. However, no study has examined what this characterization means to young Turkish voters or whether it predicts their approach to morality. In Study 1, we investigated in two separate samples the relation between young Turkish participants’ responses to the one-item left-to-right political orientation question and their self-reported political ideologies (conservative, socialist, etc.). In Study 2, we investigated the relation of moral dimensions as defined by Moral Foundations Theory to political party affiliation and political ideology. Results revealed that CHP, MHP, and AKP voters display a typical right-wing profile distinct from HDP voters. Findings regarding political ideology measures were consistent with party affiliations. Taken together, the findings reveal the distinctive nature of young Turkish people’s political orientations while supporting the predictive power of the one-item political orientation question

In her shoes : transnational digital solidarity with Muslim women, or the hijab?

Transnational solidarity has been taken up by feminist scholars, social scientists and activists who discuss or practice solidarity with the plights of different individuals, groups, and communities. This paper addresses transnational solidarity by investigating World Hijab Day, a campaign that shows solidarity with Muslim women by encouraging non‐Muslim women to temporarily wear the hijab. By analysing online activities and social media of the campaign, and investigating public debates surrounding it, the paper explores the centrality of the hijab as the unifying symbol. Results include reflections on the representations of female Muslimness, the hijab and gender roles in the campaign and insights on implications and possibility of transnational digital solidarity. Using the data, and drawing on literature of transnational solidarity, significance and implications of transnational activism in different online and digital geographies of solidarity are interrogated. The conclusion discusses the values and limits of solidarity activism that is based on notions or symbols of similarity or sameness and the role cyberspace plays in transnational reach of the campaign, and in creating online proximity

Eco-efficiency analysis for remote area power supply selection in Western Australia

Remote area power supply (RAPS) systems in Western Australia account for more than 56% of total off-grid electricity supply in Australia and utilise carbon emission intensive diesel and gas generating technologies for power supply. Most of these RAPS systems are run by environmentally unfriendly conventional fuel due to economic reasons. An eco-efficiency analysis (EEA) framework was therefore developed to explore the environmental and economic efficiency of the current diesel RAPS systems in Western Australia. ISO 14040:2006 for Life Cycle Assessment and AS/NZS 4536:1000 (R2014) for Life Cycle Costing have been used to estimate the associated environmental impacts and costs of RAPS systems in conducting an EEA. The results show that the integration of solar photovoltaic panels and an energy storage system into existing diesel generating units for power supply could improve the eco-efficiency of the existing system. It was found that a 4% increase in total life cycle costs with the use of a hybrid system could potentially decrease the overall environmental impacts by 16%
