  • Migration and Morality Amongst Sri Lankan Catholics
    UNLIKELY COSMPOLITANS: MIGRATION AND MORALITY AMONGST SRI LANKAN CATHOLICS A Dissertation Presented to the Faculty of the Graduate School of Cornell University In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Bernardo Enrique Brown August, 2013 © 2013 Bernardo Enrique Brown ii UNLIKELY COSMOPOLITANS: MIGRATION AND MORALITY AMONGST SRI LANKAN CATHOLICS Bernardo Enrique Brown, Ph.D. Cornell University, 2013 Sri Lankan Catholic families that successfully migrated to Italy encountered multiple challenges upon their return. Although most of these families set off pursuing very specific material objectives through transnational migration, the difficulties generated by return migration forced them to devise new and creative arguments to justify their continued stay away from home. This ethnography traces the migratory trajectories of Catholic families from the area of Negombo and suggests that – due to particular religious, historic and geographic circumstances– the community was able to develop a cosmopolitan attitude towards the foreign that allowed many of its members to imagine themselves as ―better fit‖ for migration than other Sri Lankans. But this cosmopolitanism was not boundless, it was circumscribed by specific ethical values that were constitutive of the identity of this community. For all the cosmopolitan curiosity that inspired people to leave, there was a clear limit to what values and practices could be negotiated without incurring serious moral transgressions. My dissertation traces the way in which these iii transnational families took decisions, constantly navigating between the extremes of a flexible, rootless cosmopolitanism and a rigid definition of identity demarcated by local attachments. Through fieldwork conducted between January and December of 2010 in the predominantly Catholic region of Negombo, I examine the work that transnational migrants did to become moral beings in a time of globalization, individualism and intense consumerism.

The reforms to the power, petroleum and postal sectors are terrorist attack on the Katunayake Bandaranayake welcome moves in this direction. International Airport (KIA) and the subsequent increase in Public investment in infrastructure development fell the war risk premium on aircraft passing through KIA short of expectations in 2001, mainly due to budgetary brought the airport operations almost to a standstill on some constraints. Public investment in economic infrastructure fell days. An increase in insurance costs due to a war risk to 3.9 per cent of GDP in 2001 in comparison to the premium, as well as labour disputes, had a serious impact original estimate of 6.0 per cent and 2000 figure of 4.4 per on port operations. The weak railway infrastructure led to cent. Public investments in social infrastructure also fell to a large number of derailments and several fatal accidents 1.0 per cent from 1.3 per cent in 2000. This level of during the year. Moreover, inadequate supply of investment is inadequate when considering the deficient infrastructure services, operational inefficiencies and issues nature of infrastructure facilities in the country.

  • Transport Sector
    The Role of Renewables in the Transport Sector 1. Current energy scenario 1.1 Background: Past & present Biofuels have the potential to displace a substantial amount of petroleum around the world over the next few decades. A clear trend in this direction can be seen by the attempts of countries like Brazil, USA, Canada and EU countries to incorporate biofuels into their national energy portfolio. Biofuels for transport include ethanol, bio-diesel and several other liquids and gaseous fuels. With increasingly stringent environmental emission standards coming up, many countries are looking at non – conventional pathways of mitigating pollution. Hence, the increased focus on biofuels. Both developed and non – developed countries have taken a keen interest. Asian countries like India, Malaysia, China and Thailand are today seriously considering the use of biofuels in the transport sector. 1.2 Current levels of energy use/mix for Sri Lanka Figure 1 represents the different types of primary energy sources currently used for catering these needs. It is also noted that more than 35% of the population do not have access to grid electricity and nearly 76% of the households can not afford gas or petroleum for cooking and depend on firewood or other forms of biomass for their daily food preparation. 8.30% 38.80% 52.90% Legend Petroleum Biomass Hydro Figure1: Primary energy sources (% of total) During the last two decades, the capacity of electricity production has rapidly increased (see Figure 2), with the aim of meeting the increasing demand at a rate of about 8% per annum. This is mainly based on hydro and thermal plants.

  • Analysis of Energy Embodied in Cement Produced in Sri Lanka
    LB/ooti/27/o3 ANALYSIS OF ENERGY EMBODIED IN CEMENT PRODUCED IN SRI LANKA A By Dampege Don Ananda Namal This thesis was submitted to the Department of Mechanical Engineering of the University of Moratuwa in partial fulfillment of the requirement for the Degree of Master of Engineering in Energy Technology. WW TheSis Coll Department of Mechanical Engineering The Faculty of Engineering University of Moratuwa Sri Lanka. 17713 February 2003 University of Moratuwa 77713 77713 t DECLARATION •A I hereby declare that this submission is my own work and that, to the best of my knowledge and behalf, it contains no material previously published or written by another person nor material, which to substantial extent, has been accepted for the award of any other acedemic qualification of a university or other institute of higher learning except where acknowledgment is made in the text. D D Ananda Namal Abstract Analysis of the embodied energy in cement produced in Sri Lanka was carried out considering national boundaries. National energy input to the cement manufacturing was the main focus of this study and therefore any energy involvement outside Sri Lanka was not taken in to consideration in this analysis. The total embodied energy content was analyzed in three levels. In level 1, direct energy consumption in manufacturing of cement at Puttalam cement factory was analyzed and energy consumption for ancillary inputs was considered in the level 2. Energy consumption for raw material extraction and transportation within the country was analyzed in level 3. The direct delivered energy consumption was assessed by carrying out an energy survey at Puttalam cement factory.
