1	Operating Efficiency Evaluation Study of Faculties in Private University -A Case Study of Certain Medical University Hsu, Fang-Yih 30 August 2010 (has links) In recent years, domestic high education institutions encounter the difficulty of decrease in numbers of enrolling students and increase in number of schools, which is resulted from the trend of less newborn children and more loosing governmental policy by Ministry of Education. In such environments, the private schools encounter high pressure of seeking sufficient enrolling students and more competition among schools. Therefore, management of private schools should focus on increasing efficiency of operating organization so private schools can be developed with more competition in the future. How to operate and allocate available resources and to achieve educational goals become the most important topics for school management. Schools are Non-Profit Organization and this thesis is intended to evaluate the relative efficiency of faculties of colleges or universities with Data Envelopment Analysis¡]DEA¡^, which is popular methods for researches regarding Non-Profit Organization. It includes the CCR model and BCC model and selects 4 input items and 3 output items as evaluation indicators. The thesis employed the DEA model in the case study to evaluate the Overall Efficiency, Pure Technical Efficiency and Scale Efficiency of school faculties and performed slack variable analysis to inefficient faculties to obtain inefficiency reasons and provide further improvements. The case study in this thesis was performed with efficiency evaluation on 19 faculties of certain medical university based on the information of fiscal year of 2008. The results were as below: 1.Overall Efficiency: In the case study, 7 faculties are relatively inefficient, representing 37% of population. This means that over 1/3 of total population is inefficient. 2.Pure Technical Efficiency: In the case study, 3 faculties have no pure technical efficiency, representing 16% of population. The negative result is less than overall efficiency, which implies that the inefficiency may be caused by scale inefficiency. 3.Scale Efficiency: In the case study, 7 faculties have no scale efficiency, representing 37% of population. Such faculties need to adjust their scales to reach the overall efficiency. This thesis also provided the improvement suggestions for inefficient faculties and operation strategies for management. operating efficiency Non-Profit Organization DEA Data Envelopment Analysis private university
2	The Impacts of Foreign Banks’ Management Model on Their Degree of Localization and Operating Efficiency in China January 2016 (has links) abstract: This thesis aims to investigate the impacts of foreign banks’ management model on their degree of localization and operating efficiency. I decompose their management model into five major factors, including two formative factors and three reflective factors. The two formative factors are (1) strategic orientation and (2) target customers, and the three reflective factors are (1) top management team composition, (2) organizational structure, and (3) managerial authority and incentives. I propose that the formative factors influence foreign banks’ degree of localization, as demonstrated by the reflective factors, which subsequently influence foreign banks’ operating efficiency in China. To test the above proposition, I conduct the empirical analysis in three steps. In the first step, I investigate foreign banks’ management model by surveying 13 major foreign banks locally incorporated in Mainland China. The results suggest that these 13 foreign banks can be categorized into three distinct groups based on their management model: intergrators, customer-followers, and parent-followers. The results also indicate that intergrators have the highest level of localization while parent-followers have the lowest level of localization. In the second step, I conduct DEA (Data Envelope Analysis) and CAMEL (Capital Adequacy, Asset Quality, Management, Earnings, Liquidity Analysis) to assess the operating efficiency of these 13 foreign banks. The assessment is conducted in two ways: 1) the inter-group comparison between foreign banks and local Chinese banks; 2) the intra-group comparison between the three distinct groups of foreign banks identified in the first step. The results indicates that the principal factor driving the operating efficiency of both local Chinese banks and foreign banks is the comprehensive technical efficiency, which includes both the quality of management and the quality of technical elements. I also find the uptrend of technical efficiency of the integrators is more stable than that of the other two groups of foreign banks. Finally, I integrate the results from step one and step two to assess the relevance between foreign banks’ localization level and operating efficiency. I find that foreign banks that score higher in localization tend to have a higher level of operating efficiency. Although this finding is not conclusive about the causal relationship between localization and operating efficiency, it nevertheless suggests that the management model of the higher performing integrators can serve as references for the other foreign banks attempting to enhance their localization and operating efficiency. I also discuss the future trends of development in the banking industry in China and what foreign banks can learn from local Chinese banks to improve their market positions. / Dissertation/Thesis / Doctoral Dissertation Business Administration 2016 Banking localization strategy locally-incorporated foreign banks management model operating efficiency
3	An Evaluation of Hospital Capital Investment after the Balanced Budget Act Kim, Tae Hyun 01 January 2006 (has links) Capital investments in the latest medical equipment and the replacement of aging facilities are important hospital decisions because they may have a significant influence on operating efficiencies and quality of care. However, hospitals experienced a minimal growth rate in capital expenditures which contributed to the aging of the hospital industry's asset base during the late 1990's and early 2000's. One of the underlying reasons behind this lack of growth might be the financial stresses that hospitals were facing after the Balanced Budget Act (BBA) of 1997, which significantly reducedMedicare reimbursement and had an adverse impact on the financial viability of hospitals. The objective of this study is to empirically evaluate how changes in market, operational and financial factors influence changes in hospital capital investment in the post BBA period.The study employs a panel of nonprofit private and public, short-term general hospitals from 1998 to 2001. Six secondary databases were merged and analyzed by first difference transformation and instrumental variable estimation to eliminate unmeasured, time-invariant hospital characteristics, and to address the endogeneity and possible feedback effects of regressors in the model.The results of the study suggest that changes in hospital capital investment appear to be positively associated with changes in the ratio of primary care physicians to all physicians in market, the size of population, and the ratio of population age 65 over to all population in market. Also significant is change in the age of plant for hospitals that exhibits a negative association with change in capital investment. As expected, the study observes a strong positive effect of changes in liquidity and cash flow on changes in capital investment. However, the effect of change in debt ratio on change in capital investment appears to be marginally significant.Estimation of the effects of changes in variety of factors on changes in hospital capital investment especially in the post-Balanced Budget Act period indicates that hospitals appear to increase their capital expenditures to accommodate the increasing market demand for hospital services, and the results also show that availability of resources, especially financial ones, are most likely to influence capital investment during the financially stressed environment.This study contributes to a limited body of research examining factors affecting capital investment at the hospital level and demonstrates the important role of internal funds in predicting future hospital capital investment.

A amostra foi formada por 159 companhias, sendo 57 pertencentes e 102 não pertencentes à carteira ISE. O período de análise compreende os anos de 2005 a 2014, correspondendo o ano de 2005 à criação do ISE. A análise dos dados foi efetuada mediante a utilização da análise envoltória de dados (DEA - data envelopment analysis) pelo método BCC, definido por Banker, Charnes e Cooper (1984), também conhecido como retorno variável de escala (VRS - variable returns to scale) com orientação ao produto, ou seja, a maximização dos outputs. As variáveis utilizadas na análise como inputs foram o ativo circulante, ativo imobilizado e o custo dos produtos vendidos e como output o lucro operacional. Toda a análise foi desenvolvida observando os segmentos de cada grupo de empresa da amostra de forma isolada, visando evitar distorção nos dados. Os resultados obtidos revelam que as companhias da carteira ISE apresentam eficiência operacional inferior às demais companhias, à medida que não alcançaram eficiência operacional de 100% (DEA – BCC – VRS) ao longo dos anos, o que leva a se concluir que o fato dessas companhias serem consideradas como de conduta sustentável, isso necessariamente não se reflete em sua eficiência operacional. / The research aimed to analyze the operational efficiency of companies belonging and not belonging to the theoretical portfolio of the Corporate Sustainability Index (ISE) of BM&FBOVESPA through data envelopment analysis. The sample was comprised of 159 companies, of which 57 owned and 102 non-ISE. The analysis period covers the years 2005 to 2014, corresponding to 2005 to the ISE creation. Data analysis was performed by using the data envelopment analysis (DEA) by the BCC method defined by Banker, Charnes and Cooper (1984), also known as variable returns to scale (VRS) with the product orientation, that is, the maximization of output. The variables used in the analysis were as inputs current assets, fixed assets and the cost of sales and operating profit as output. All analysis was developed observing the segments of each company in the sample group in isolation, in order to avoid distortion in the data. The results show that the ISE portfolio companies have lower operating efficiency to other companies, as they have not achieved operating efficiency of 100% (DEA - BCC - VRS) over the years, which leads to the conclusion that the fact that these companies are considered sustainable conduct, not necessarily reflected in operational efficiency.

Desde o paradoxo da produtividade (BRYNJOLFSSON, 1993), conseguiu-se mostrar a influência positiva da TI principalmente para as empresas grandes e, apenas mais recentemente, têm surgido pesquisas realizadas em pequenas e médias empresas. A urgência por se conhecer melhor esse tema, a carência de pesquisas sobre o setor brasileiro de bens de capital e o recente crescimento dele na economia do país são justificativas para a realização deste trabalho. Para o desenvolvimento desta investigação, utilizaram-se as técnicas de correlação estatística e de Análise Envoltória de Dados (Data Envelopment Analysis - DEA), além de análises fatoriais, através da seqüência: definições de conceitos; uso de metodologia apropriada para análise dos Fatores Críticos de Sucesso e análise dos Indicadores de Desempenho das empresas do setor de bens de capital; determinação dos inputs e outputs do modelo DEA; elaboração dos Fatores de Informatização; elaboração de construtos para aplicação da técnica DEA em dois estágios; elaboração de questionário para obtenção dos dados junto às empresas do setor; seu envio eletrônico; levantamento dos dados recebidos; análise descritiva; análise fatorial dos fatores de informatização; análise correlacional dos principais indicadores e variáveis; aplicação da técnica DEA nos construtos global, primeiro estágio e segundo estágio; análise dos resultados de eficiência; e análise correlacional entre os índices de eficiência e os fatores de informatização. O questionário elaborado foi testado previamente com três empresas, contando-se também com o auxílio de um consultor da Associação Brasileira da Indústria de Máquinas e Equipamentos (ABIMAQ) para refiná-lo e simplificá-lo. A lista de 3.833 empresas, entre associadas e não-associadas, foi fornecida pela própria ABIMAQ, e o questionário e suas respostas foram transmitidos via correio eletrônico da Universidade de São Paulo. Desse universo, que é formado principalmente por micro e pequenas empresas que trabalham sob encomenda, 80 responderam, e dessas, 28 puderam ser aproveitadas para comporem o grupo testado pelo método DEA. Dentre os resultados obtidos, destacam-se a associação positiva entre porte das empresas e melhores práticas, a relação entre a participação dos executivos e os fatores de informatização, a correlação entre os fatores de informatização e a eficiência operacional, a maior capacidade das empresas menores em converter o uso da TI em eficiência operacional e a maior capacidade das empresas maiores em converter os fatores críticos de sucesso em rentabilidade. Dentre os subsetores estudados, o de máquinas-ferramenta destacou-se nas atividades apoiadas pela TI e na extensão de seu uso. / The debate surrounding the use of IT and its consequences for companies is still incomplete. Since the Productivity Paradox (BRYNJOLFSSON, 1993), the positive influence of IT on large companies has been shown, and only recently has research regarding small and medium companies been developed.

9	Analysis of a novel thermoelectric generator in the built environment Lozano, Adolfo 05 October 2011 (has links) This study centered on a novel thermoelectric generator (TEG) integrated into the built environment. Designed by Watts Thermoelectric LLC, the TEG is essentially a novel assembly of thermoelectric modules whose required temperature differential is supplied by hot and cold streams of water flowing through the TEG. Per its recommended operating conditions, the TEG nominally generates 83 Watts of electrical power. In its default configuration in the built environment, solar-thermal energy serves as the TEG’s hot stream source and geothermal energy serves as its cold stream source. Two systems-level, thermodynamic analyses were performed, which were based on the TEG’s upcoming characterization testing, scheduled to occur later in 2011 in Detroit, Michigan. The first analysis considered the TEG coupled with a solar collector system. A numerical model of the coupled system was constructed in order to estimate the system’s annual energetic performance. It was determined numerically that over the course of a sample year, the solar collector system could deliver 39.73 megawatt-hours (MWh) of thermal energy to the TEG. The TEG converted that thermal energy into a net of 266.5 kilowatt-hours of electricity in that year. The second analysis focused on the TEG itself during operation with the purpose of providing a preliminary thermodynamic characterization of the TEG. Using experimental data, this analysis found the TEG’s operating efficiency to be 1.72%. Next, the annual emissions that would be avoided by implementing the zero-emission TEG were considered. The emission factor of Michigan’s electric grid, RFCM, was calculated to be 0.830 tons of carbon dioxide-equivalent (CO2e) per MWh, and with the TEG’s annual energy output, it was concluded that 0.221 tons CO2e would be avoided each year with the TEG. It is important to note that the TEG can be linearly scaled up by including additional modules. Thus, these benefits can be multiplied through the incorporation of more TEG units. Finally, the levelized cost of electricity (LCOE) of the TEG integrated into the built environment with the solar-thermal hot source and passive ground-based cold source was considered. The LCOE of the system was estimated to be approximately $8,404/MWh, which is substantially greater than current generation technologies. Note that this calculation was based on one particular configuration with a particular and narrow set of assumptions, and is not intended to be a general conclusion about TEG systems overall. It was concluded that while solar-thermal energy systems can sustain the TEG, they are capital-intensive and therefore not economically suitable for the TEG given the assumptions of this analysis. In the end, because of the large costs associated with the solar-thermal system, waste heat recovery is proposed as a potentially more cost-effective provider of the TEG’s hot stream source. / text Thermoelectric generator TEG Novel thermoelectric generator Thermoelectrics Thermoelectric effect Thermoelectric modules Thermoelectric device Patent application Hot stream source Cold stream source EIA EERE Systems-level analysis Energy balance Control volume analysis Thermodynamic analysis Insolation data Insolation incident on a panel Incident insolation Extraterrestrial insolation NREL Ambient temperature data NOAA Renewable energy sources Energy generation technology Electricity generation technology Thermal energy Coupled system Emissions Greenhouse gas GHG Emissions analysis Zero-emission Emissions avoided Emission factor EF Reliability First Corporation RFC Built environment Integrated into the built environment Solar-thermal energy Solar collector system Photovoltaic thermal PVT panel Thermal storage tank Geothermal energy Geothermal heat pump GHP Ground source heat pump GSHP Numerical analysis Numerical model MATLAB Finite-difference Euler explicit Electric grid Annual energetic performance Annual electricity generation Operating efficiency System efficiency Thermodynamic characterization Economic analysis Levelized cost of energy LCOE Waste heat recovery Carbon dioxide equivalent CO2e Capital costs Installed costs Operating and maintenance costs
