This factory employs just over 2,000 Myanmar migrant workers. The authors study their "everyday life practices" as expressed in relationships among various groups, such as relationships between the Myanmar migrant workers and the factory, and the relationships between the Myanmar migrant workers and the Thai people of the surrounding communities. In analyzing these relationships and negotiations, the authors borrow the concept of "tactics of everyday life" from Michel de Certeau as a framework for analysis. The authors' analyses are based on in-depth interviews, non-participant observations, and focus-group discussions that collectively explored the tactics, in de Certeau's sense, that the Myanmar migrant workers used in negotiating their relationships with the factory and with the various communities in the area. The results indicate that Myanmar migrant workers negotiate their relationship with the factory by expressing themselves as selected workers, good workers, and being obedient to the factory's rules. The conflicts caused by Myanmar and Cambodian migrant workers are negotiated. Besides, Myanmar migrant workers also negotiate their relationship with the Thai people living in the surrounding communities. Their approach is showing that they are part of the communities by participating in the activities with the aim to gain acceptance of the Thai people in the surrounding communities.展开更多

Strict economic regulation of the DSOs (distribution system operators), forces them to search for more efficient work processes and improved technical solutions. The main challenges for network companies today are implementing new technologies and become more efficient in every part of the asset management. The work processes must be optimized and the right projects must be prioritized for reinvestment. The purpose of this paper is to give insight into some of the challenges electric distribution companies are facing today. This paper is based on experiences from NTE Nett AS--an electric distribution company in the middle of Norway. The paper also describes some of the measures that have been done in NTE Nett and what people believe will be the situation in the future.展开更多

However, the unsatisfying energy density is the inhabiting issue for the wide commercial applications. As the energy density(E, W h kg?1) is directly proportional to specific capacitance(C, F g?1) and the square of operating voltage(V, V), in this review, we summarize the recent progress in two sections: the exploration of high-performance electrode materials to achieve high specific capacitance and the construction of high-voltage supercapacitor systems for high working voltage. The progressive explorations and developments in supercapacitors could guide the future research towards high-performance, low-cost, and safe energy storage devices.展开更多
