1	China's Electric Power Industry Reform: An Empirical Investigation Shao, Bin January 2010 (has links) Electric power has become the most widely used secondary energy. As a result, the electricity industry's development will, in turn, directly influence other industries, people's daily lives, and the whole economy. China is one of the most rapidly developing economies, making it one of the biggest consumer of electricity in the world. Thus, the development of electric industry in China is not only important for the development of China itself, but also the energy pattern all over the world. In this study, we focus on analysing the market-oriented reform in China's electricity industry after the adoption of reforming and opening policies in 1978. By following the time path, the detailed content of the reform, as it was applied and modified over time, is first introduced. Then, an empirical investigation is conducted on the major policies in the process of China's electric power industry reform. Through quantitative measurement, the contribution of each major policy is clearly defined, so that conclusions concerning the reform in the past and suggestions for its future direction can be reached and made. It is found that both successes and deficiencies occurred in the reform process, and that China's electric industry has made significant efforts to overcome obstacles as they have been identified. However, even though great progress has been made in China's electric power industry from 1978 to 2009, more efforts are still required to finally achieve market operation in the industry. It is expected that this study can positively contribute to the development of China's electric power industry, as well as to electric power industries in other countries.

2	A case study of accountability for special education service delivery : a mixed model analysis Degenhardt, Austin C 20 March 2009 There were five main purposes for the current thesis: (1) to address the need for more quantitative studies to evaluate student academic success within the inclusive classroom setting; (2) to apply a recently released program assessment rubric for special education services to determine the level of special education service delivery in the specified location; (3) to evaluate the reliability of the results of the rubric mandated by the Saskatchewan Ministry of Education (2008); (4) to compare the results of the standardized student achievement tests with the rubric results in relation to program effectiveness; and (5) to investigate potential confounding factors related to the current study design. The goal of this thesis was to provide information to the Living Sky School Division and to the Saskatchewan Ministry of Education on the implementation and success of the inclusion model in a rural Saskatchewan setting. In addition, results were intended to provide information on assessment instruments employed in the measurement of program effectiveness. The analysis was conducted as a mixed-methods case study that included two parts: (1) the first assessment indicated that students with learning difficulties scored significantly higher on standardized academic achievement measures while in an inclusive setting as opposed to scores while in a pullout setting; and (2) the second assessment determined that special education service delivery was <i>emerging/developing</i> to <i>evident</i>. The correlation coefficient of rubric results was calculated at á = .69. A variety of general measurement issues, including small sample size and use of historical data, in relation to the current study design, were discussed. rubric assessment quantitative measurement standardized testing responsive evaluation inclusion

4	Entrainment and mixing properties of multiphase plumes: Experimental studies on turbulence and scalar structure of a bubble plume Seol, Dong Guan 15 May 2009 (has links) This dissertation presents a series of laboratory experiments to study flow and mixing properties of multiphase plumes. The particle image velocimetry (PIV) and laserinduced fluorescence (LIF) techniques are developed to measure two-dimensional velocity and concentration fields of multiphase plumes. The developed measurement techniques are applied to bubble plumes in different ambient conditions. The problems and errors in the two-phase PIV application to a bubble plume case are addressed through a comparative study between the optical separation method using fluorescent particles and a new phase separation method using vector postprocessing. The study shows that the new algorithm predicts well the instantaneous and time-averaged velocity profiles and has errors comparable to those for image masking techniques. The phase separation method developed in the previous section is applied to study the mean flow characteristics of a bubble plume in quiescent and unstratified condition. The entrainment coefficients representing the mixing properties of a bubble plume are calculated to lie between 0.08 near the plume source and 0.05 in the upper region, and to depend on the non-dimensional quantity us/(B/z)1/3, where us is the bubble slip velocity, B is the initial buoyancy flux, and z is the height from the diffuser. Further, the LIF technique is investigated to measure the scalar concentration field around a bubble plume in quiescent, unstratified condition. This new application to bubble plumes accounts for light scattering by bubbles using an attenuation coef- ficient that is proportional to the local void fraction. Measured scalar concentration fields show similar trend in concentration fluctuation to turbulent plume cases. Finally, the velocity and concentration field measurements using the developed two-phase PIV and LIF methods are applied for a bubble plume in a density-stratified ambient. The turbulent flow characteristics induced by a bubble plume in a stratified ambient water are studied. The plume fluctuation frequency is measured as about 0.1 Hz and compares well to plume wandering frequency measured in unstratified plume cases. bubble plume PIV LIF mean flow properties stratification
5	Who are we and what do we measure? : A case study of the dynamic relationship between performance measurement and organizational identity Källgren, Marcus, Vejbrink Kildal, Adrian January 2022 (has links) Performance measurements have been described as a tool by which management can communicate expected standards of behavior as well as a shared meaning among members regarding the intended direction of the firm. In parallel, the organizational identity field relies on the premise that members can answer the question “who are we as an organization?” through a sense of shared understanding. The purpose of this paper is to investigate the implications a performance measurement system has on the employees’ perception of “who we are“, related to the theoretical framework of organizational identity. This paper utilizes a qualitative research method, a case-based approach of a Swedish life science company which is conducted in an exploratory manner. The case company is chosen due to its contextual setting regarding the newly implemented performance measurement system, along with the inherent characteristics of the industry in general, which is typically considered to be incongruent with such quantitative measurements. The empirical data is collected through eight interviews with members from the chosen case company, as well as through internal documents describing its performance measurement system. The authors propose a revised theoretical framework in which performance measurements and organizational identity are investigated through a conceptual model which explores their dynamic relationship. The findings reinforce well-known ideas of performance measurements and organizational identity, along with providing new insights on the dynamics between them.
