The Japanese cuisine is the largest number of exotic dishes in Taiwan. The past researches of Japanese that ignoring the evolution of variety of types of Japanese cuisine see cuisine as a single cuisine type. The purpose of this study is to investigate the Japanese cuisine taste differentiation patterns and social significance. I used Bourdieu¡¦s taste segmentation theory to analysis. Using depth interviews and historical documents to make a thorough inquiry. I classified Japanese cuisine into family-style, kaiseki ryori , buffet style all you can eat as well as chain stores, and pointed out the different types of stores will develop different taste.I found that except for the chain and buffet style all you can eat, other types of Japanese cuisine will emphasize ingredients imported from Japan, the chef's cooking skills, and a fresh source. Kaiseki ryori emphasized orthodoxy, relatively inexpensive family cuisine stressed Taiwanese taste to prefer popularity. And cultural performance , the atmosphere of the the traditional family-style Japanese will tend to show Japanese culture, highlighting the cuisine of different countries with it. Kaiseki ryori or chain is modern style, with different family-style. The study found that different types of Japanese cuisine in the process to create taste have distinction between others and showed their class status.

This research study was conducted as a qualitative case study of six middle class African American mothers living in a suburban community. Their children attended a predominantly White suburban junior high school in their community. The study was designed to hear the voices of the six mothers and their perceptions of their children’s experiences in suburban schools. The intent of this study was to broaden the limited research base relating to the academic achievement of African American students from the mothers’ perspective. Specifically, this study investigated the African American mothers’ perception of their children’s interactions with their White teachers and the difficulties their children faced in advanced placement courses. This study used the specific words of the mothers to share their narratives. Data were collected through open-ended, semi-structured individual interviews followed by focus group sessions. Data collection and analysis occurred simultaneously from the interviews, focus group sessions, and field notes. From the analysis, themes emerged and were formulated into categories. The results revealed that mothers perceived: (a) teachers as holding a lack of cultural appreciation for their children’s culture, (b) low expectations held by the teachers (students constantly had to prove their ability), (c) a lack of communication from the teacher to the mother, (d) the teachers’ lack of understanding of the mothers’ preparation of the success of their children, (e) the need to maintain a role of advocacy, (f) the need to maintain a role of visibility, and (g) the need to maintain a role of proactive parenting.

This dissertation analyzes the effect of smaller classes on student performance using student-level test score data from the state of Texas, focusing on three specific issues: heterogeneity in the returns to smaller classes across a score distribution of students, the relationship between class size and students' moving decisions, and the connection between smaller classes and schools' class division procedures. I first examine evidence of heterogeneity in the returns to class size reductions across a score distribution of students. I divide students into decile groups based on their previous year test scores, and I estimate the returns to smaller classes for each of the deciles. The empirical evidence supports the hypothesis that there are significant differences in students' responses to class size, based on their previous test scores. I then model the class size effect simultaneously with students' decisions to switch schools, which is important because movers compose a substantial fraction of the dataset, and because class size effects vary between movers and nonmovers. Recognizing that students move for different reasons, only some of which are school-related, I present a two-type moving model in which students are categorized as endogenous movers or exogenous movers. I estimate the model estimated using maximum likelihood. The results reveal key biases in traditional estimates of the moving effect and suggest significant differences in the class size effect across mover types. I also explore the class size effect in conjunction with schools' decisions to sort students into different classes. Using student-level data in which students are linked to specific classes, I disentangle the class size effect from the sorting effect. Including a variable indicating the sorting index of a school decreases the magnitude and significance of the class size effect. I also examine different types of sorting. The findings suggest that sorting students into more homogeneous groups is beneficial for both high and low scoring students.

An FM transmitter becomes the new feature in recent portable electronic development. A low power, integrable FM transmitter filter IC is required to meet the demand of FM transmitting feature. A low pass filter using harmonic rejection technique along with a low power class-AB output buffer is designed to meet the current market requirements on the FM transmitter chip. A harmonic rejection filter is designed to filter FM square wave signal from 70MHz to 110MHz into FM sine wave signal. Based on Fourier series, the harmonic rejection technique adds the phase shifted square waves to achieve better THD and less high frequency harmonics. The phase shifting is realized through a frequency divider, and the summation is implemented through a current summation circuit. A RC low pass filter with automatic tuning is designed to further attenuate unwanted harmonics. In this work, the filter's post layout simulation shows -53dB THD and harmonics above 800MHz attenuation of -99dB. The power consumption of the filter is less than 0.7mW. Output buffer stage is implemented through a resistor degenerated transconductor and a class-AB amplifier. Feedforward frequency compensation is applied to compensate the output class-AB stage, which extends the amplifier's operating bandwidth. A fully balanced class-AB driver is proposed to unleash the driving capability of common source output transistors. The output buffer reaches -43dB THD at 110MHz with 0.63Vpp output swing and drives 1mW into 50 load. The power consumption of the output buffer is 7.25mW. By using harmonic rejection technique, this work realizes the 70MHz-110MHz FM carrier filtering using TSMC 0.18um nominal process. Above 800MHz harmonics are attenuated to below -95dB. With 1.2V supply, the total power consumption including output buffer is 7.95mW. The total die area is 0.946mm2.

Modeling software with object-oriented technique and Unified Modeling Language (UML) has become the new paradigm of modern information systems analysis and design. Selonen et al. (2003) proposed a framework for transformation within UML. However, they do not precisely define the operations and the rules they use. This research presents a systematic method which enhances Selonen et al.¡¦s work to transform the sequence diagram into the class diagram. The transformation process consists of three phases: (1) mapping the given sequence diagram to a notation-independent and semantically equivalent minimal model, (2) transforming the minimal model of the sequence diagram into the minimal model of a class diagram, and (3) mapping the minimal model to a class diagram. A real-world case is used to illustrate the concepts, application, and the advantages of using the proposed method. With this approach, the system developer can transform sequence diagram into class diagram automatically and thereby enhance the efficiency of system development.

How does Chinese society define the class and stratum? Why do the classified methods and the standards of the class and stratum take place? The thesis primarily concentrates on studying the class and stratum in Chinese society. Reviewing class and stratification concepts, the reexamination of theories and the establishment of analytical framework, the thesis claims that the classified methods of the class and stratum are usually motivated by political purposes. That is to say, new class and the stratum categories derive from the alternations of political purposes. Hence, in addition to assisting readers to understand how Chinese class and stratum are classified, the result of the research can also predict the future development of class and stratum in Chinese society by means of the reformation of politics, economy, and the society.

Today, modeling the software with unified modeling language (UML) and computer-aided software engineering (CASE) tool becomes the main stream for the objected-oriented systems analysis and design. To enhance the degree of ransformation automation and reuse in the system development process, prior research suggested that most parts of the class diagram can be transformed from the sequence diagram directly. However, the explicit guideline for the transformation is lacking. This study presents a methodology, extended from Selonen et al (2003), to transform the sequence diagram into the class diagram. A real-world case using the integrated techniques is presented to illustrate the concepts, application, and the advantages of using the proposed approach. With this approach, the system developer can transform most parts of the sequence diagram into its associated class diagram automatically and thereby enhance the efficiency of system development.

The point of the problems of peasant workers in city is that the binary economy in China city and country has separated peasants and city residents as two different identity systems. Household system was deployed in China in 1950 to strictly limit the labor force of rural village, peasants were isolated from the city, and rural village became the sacrifice under the industrialization policy and developed slowly. Peasant workers play a vital role in the procedure of economy development in mainland China in recent years, the enormous and cheap labor force attracts foreign capital and Taiwan capital enterprises involve into China market to lead the development of district economy, it became a problem that China government put emphasis on due to the gradually emerge of labor dispute and social conflicts. Peasant workers have no opportunity to participate in social and political life; have no ability to maintain self rights, and become the ¡§silent class¡¨ in the city society. In the respect of economy, the labor disputes emerged in endless caused by the delay payment to peasant workers and resulted in sever social public security incidents, and laid a layer of shade upon the ¡§harmony society¡¨ leaded by Chinese Communist Party; in the respect of society, the class of peasant workers isn¡¦t approved by the city, the social exclusion and prejudice are all-pervasive owing to the enlargement of the gap between the rich and poor and created profound painful influence on the social attitude of peasant workers. The problem of peasant workers reflects not only the market failure due to imperfect market system but also the failure of the policies of Chinese Communist Party, and the emerge of civil organizations compensate the gap between the government and society, the NGOs of China thereby concern the problems of peasant workers and attempt to get involve in the aspects that government can¡¦t achieved. This text dissertates mainly from the social levels and class respects to explore the status of peasants and causes of being discriminated; to analyze the leadership of Chinese Communist Party how to bring up corresponding solution focused on the sever social problems caused by peasant workers; to explore whether the relationship between nation and society also changed in Mainland China during the development procedure of peasant workers and what¡¦s the context and direction of change.

After well-known structured technology, object-oriented technology has become another paradigm of system development and a hot topic in the field of software engineering. The Unified Modeling Language (UML) has become a standard means for the analysis and design of object-oriented after it passed the certification of the Object Management Group (OMG) in 1997, and it was widely used in many industries. Although it becomes a standard of object-oriented modeling language, UML hasn¡¦t provided principles or guidelines for mapping classes to tables. The purpose of this study is to investigate the guidelines for transforming UML class diagram to object-relational model. The transferring methods include both static structure transfer and dynamic behavior transfer. An example of automobile ordering system is used to illustrate the guideline and application. With these guidelines, analysts can easily use the UML class diagram to express database designing and thereby improve the efficiency and effectiveness of UML modeling.

This thesis consists of two parts. Part 1 introduces the characteristics of Class E power amplifier. Part 2 is focused on the implementation of Class E power amplifier for 2.4GHz Bluetooth applications. The design procedure follows the theory of class E power amplifier, and is implemented in MMICs and modules. For MMICs, the GaAs HBT foundry services are provided by the GCTC Ltd. and WIN Ltd.. Under single supply voltage of 3.3V and the output power of 20dBm, two designed MMICs have gain 23dB and 11dB, and power added efficiency (PAE) 57% and 72%, respectively. For Hybrid modules, RF transistors are provided by the Filtronic Ltd.. Under the same supply voltage of 3.3V, the measured output power, gain, and power added efficiency are 20 dBm, 25dB, and 75% respectively. Compared with the other types of power amplifiers on the market, Class E power amplifier has higher power added efficiency, and thus can increase the using time of communication system.
