"Am I Korean American?": beliefs and practices of parents and children living in two languages and two cultures

The purpose of this study is to explore attitudes and practices regarding their heritage language and the dominant English language among Korean American immigrant families. Using the framework of Language Ideology (Silverstein, 1979), I had three research questions: a) why do parents send their children to a Korean language school, b) what attitudes do immigrant parents and their children show toward Korean and English, and c) how are the parents and children involved in the practices of these two languages? I conducted a survey of parents whose children attended a Korean language school in Urbana-Champaign, Illinois, where the number of Korean sojourners (temporary residents) exceeds that of Korean immigrants. Forty participant parents provided demographic information. They described their children's language-use patterns depending on interlocutors as well as their language proficiency in both Korean and English. The reasons for sending their children to the Korean language school were significantly different depending on the respondents' residential status. In comparison to the sojourners, immigrants tended to give more priority to their children's oral language development and Korean identity construction. I also conducted case studies of three Korean immigrant families with 3- to 5-year-old children, using interviews, observations, and photographs of children's work. The collected data were analyzed according to themes such as daily life, parental beliefs about two languages, practices in two languages, children's attitudes toward two languages, and challenges and needs. Despite individual families' different immigration histories, the three families faced some common challenges. Because of their busy daily routines and different lifestyles, the immigrant families had limited interactions with other Koreans. The parents wanted their children to benefit from two communities and build a combined ethnic identity as Korean Americans. I argue that a Korean language school should expand its role as a comfort zone for all Koreans and Korean Americans. This study explores the heterogeneity among Korean sojourner and immigrant families and their language use and identity construction.

NETCODE: an XOR-based warning dissemination scheme for vehicular wireless networks

The next generation of vehicles will be equipped with automated Accident Warning Systems (AWSs) capable of warning neighbouring vehicles about hazards that might lead to accidents. The key enabling technology for these systems is the Vehicular Ad-hoc Networks (VANET) but the dynamics of such networks make the crucial timely delivery of warning messages challenging. While most previously attempted implementations have used broadcast-based data dissemination schemes, these do not cope well as data traffic load or network density increases. This problem of sending warning messages in a timely manner is addressed by employing a network coding technique in this thesis. The proposed NETwork COded DissEmination (NETCODE) is a VANET-based AWS responsible for generating and sending warnings to the vehicles on the road. NETCODE offers an XOR-based data dissemination scheme that sends multiple warning in a single transmission and therefore, reduces the total number of transmissions required to send the same number of warnings that broadcast schemes send. Hence, it reduces contention and collisions in the network improving the delivery time of the warnings. The first part of this research (Chapters 3 and 4) asserts that in order to build a warning system, it is needful to ascertain the system requirements, information to be exchanged, and protocols best suited for communication between vehicles. Therefore, a study of these factors along with a review of existing proposals identifying their strength and weakness is carried out. Then an analysis of existing broadcast-based warning is conducted which concludes that although this is the most straightforward scheme, loading can result an effective collapse, resulting in unacceptably long transmission delays. The second part of this research (Chapter 5) proposes the NETCODE design, including the main contribution of this thesis, a pair of encoding and decoding algorithms that makes the use of an XOR-based technique to reduce transmission overheads and thus allows warnings to get delivered in time. The final part of this research (Chapters 6--8) evaluates the performance of the proposed scheme as to how it reduces the number of transmissions in the network in response to growing data traffic load and network density and investigates its capacity to detect potential accidents. The evaluations use a custom-built simulator to model real-world scenarios such as city areas, junctions, roundabouts, motorways and so on. The study shows that the reduction in the number of transmissions helps reduce competition in the network significantly and this allows vehicles to deliver warning messages more rapidly to their neighbours. It also examines the relative performance of NETCODE when handling both sudden event-driven and longer-term periodic messages in diverse scenarios under stress caused by increasing numbers of vehicles and transmissions per vehicle. This work confirms the thesis' primary contention that XOR-based network coding provides a potential solution on which a more efficient AWS data dissemination scheme can be built.

Ética na pesquisa em Administração

Ethics on scientific research is approached and often discussed in several areas of knowledge connected to health. In the Administration area there are very few studies which approach the topic of ethics on research. The present paper tried to fill in this gap in the production of knowledge about the topic, investigating how the ethical principles found in the literature and in the codes of conduct are noticed and taken into account in Administration research activities developed by acting researchers in Administration Post Graduation Programs. Theoretically speaking, the study was based mainly on the approaches by Creswell (2007) and Bell and Bryman (2007), which discuss the research ethical principles. Methodologically speaking it was all about an exploratory kind of study, with qualitative research approach. Upon data collection, personal interviews were made aiming at its depth and focus groups were formed. The first stage had interviews with four experienced researchers who took part on a teaching and researching event and on the second stage we used the focus group technique. The focus groups were done in four college institutions along with the post graduation programs in Administration in the states of Rio Grande do Norte, Paraíba and Pernambuco, in Brazil. The results suggest the existence of general principles and parameters for the scientific research recommended in the literature and on official resolution. However, in the Administration area, there are only a few recommendations of good practices when it comes to submitting articles for scientific publications but we found no guidance with ethical principles and parameters which cover all the activities in the scientific research and which specifically meet the research particularities in Administration. The main ethical dilemma pointed by the researchers refers to ethical questions which arise at the time of data collection and on disclosing the results. Most researchers do not know the guidelines and the ethical norms on ethics about research that we have in our country neither do they send in their projects to the research ethics committee. When dilemma arises, they decide the ethical question based on their values and common sense. These elements confirm the thesis that the researcher s procedure in the research activities in Administration is predominantly signed by personal values or by common sense and less by ethical principles, whether by not knowing the normative instruments related to ethics or by disagreeing with any disciplining rules on ethical behavior in the research

Notoriedade dos produtos tradicionais de origem animal (DOP e IGP) do Alentejo

O presente trabalho visa conhecer o nível de notoriedade dos produtos tradicionais de origem animal (DOP e IGP) do Alentejo no mercado consumidor. Este objectivo foi alcançado através da realização de revisão bibliográfica com recurso às fontes secundárias disponíveis e de fontes primárias, nomeadamente de um questionário de avaliação da notoriedade dos produtos tradicionais (DOP e IGP) de origem animal do Alentejo expressamente desenvolvido para o efeito. A informação obtida permitiu caracterizar a oferta dos produtos tradicionais de origem animal do Alentejo, em termos quantitativos, qualitativos e diversidade, enquadrar teoricamente o tema da notoriedade no contexto do comportamento do consumidor e do marketing agro-alimentar e identificar os procedimentos metodológicos a serem utilizados e delineamento do trabalho de investigação. A análise dos dados recolhidos por inquérito, tratados com recurso a software e técnicas estatísticas descritivas, permitiram retirar conclusões relevantes, tais como a baixa notoriedade dos produtos DOP e IGP, o produto com mais notoriedade, Top-of-Mind, a Carnalentejana, entre outros. Foram identificados tanto nas fontes primárias como nas secundárias aspectos em comum: uma baixíssima notoriedade dos produtos certificados e uma preocupação e necessidade em haver mais acções de divulgação destes produtos. Dos 33 produtos certificados de origem animal do Alentejo, apuraram-se que apenas 26 se encontram a ser comercializados e em que muitos casos os agrupamentos remetem para os produtores a responsabilidade da promoção dos produtos. Foram ainda identificados tópicos para futuras pesquisas e para acções de marketing tendentes a melhorar a notoriedade dos produtos tradicionais de origem animal do Alentejo no mercado. ABSTRACT; The present work aims to know the level of renown of the traditional products of animal origin (DOP and IGP) of the Alentejo in the consumer market. This objective was reached through the realization of bibliographical revision with resource to the available secondary fountains and of primary fountains, namely of a questionnaire of evaluation of the renown of the traditional products (DOP and IGP) of animal origin of the Alentejo definitely developed for the effect. The obtained information allowed to characterize the offer of the traditional products of animal origin of the Alentejo, in quantitative, qualitative terms and diversity, to fit theoretically the subject of the renown in the context of the behavior of the consumer and of the food-rough marketing and to identify the methodological proceedings being used and delineation of the work of investigation. The analysis of the data gathered by inquiry, treated with resource the software and descriptive statistical techniques, allowed there withdrew relevant conclusions, such as the low renown of the products DOP and IGP, the product with more renown, Top-of-Mind, was the Carnalentejana, between others. Aspects were identified so much in the primary fountains how in secondary in common: a low renown of the certified products and a preoccupation and necessity in having more actions of spread/promotion of these products. Of 33 products made sure of animal origin of the Alentejo, they perfected that you punish 26 they are being marketed and in what many cases the groupings send for the producers the responsibility of the promotion of the products. Topics were still identified for future inquiries and for tending actions of marketing to improve the renown of the traditional products of animal origin of the Alentejo in the market.

A four-dimensional analysis of the thermal structure in the Gulf of Lion

The Theoretical and Experimental Tomography in the Sea Experiment (THETIS 1) took place in the Gulf of Lion to observe the evolution of the temperature field and the process of deep convection during the 1991-1992 winter. The temperature measurements consist, of moored sensors, conductivity-temperature-depth and expendable bathythermograph surveys, ana acoustic tomography. Because of this diverse data set and since the field evolves rather fast, the analysis uses a unified framework, based on estimation theory and implementing a Kalman filter. The resolution and the errors associated with the model are systematically estimated. Temperature is a good tracer of water masses. The time-evolving three-dimensional view of the field resulting from the analysis shows the details of the three classical convection phases: preconditioning, vigourous convection, and relaxation. In all phases, there is strong spatial nonuniformity, with mesoscale activity, short timescales, and sporadic evidence of advective events (surface capping, intrusions of Levantine Intermediate Water (LIW)). Deep convection, reaching 1500 m, was observed in late February; by late April the field had not yet returned to its initial conditions (strong deficit of LIW). Comparison with available atmospheric flux data shows that advection acts to delay the occurence of convection and confirms the essential role of buoyancy fluxes. For this winter, the deep. mixing results in an injection of anomalously warm water (Delta T similar or equal to 0.03 degrees) to a depth of 1500 m, compatible with the deep warming previously reported.

Entre o cartão-postal e a cidade real: um estudo sobre paisagem e produção imobiliária em Natal/RN

Recent studies concerning the landscape have investigated the most important activities that contribute for its modification and have tried to better understand the society through the marks left by its quotidian. It is understood that singular landscapes constitute the cultural patrimonies of the cities, once they are part of the daily life of the citizens and are present in their social representations. Some contemporary authors defend the preservation of the natural and urban landscape trying, specially, to keep its importance for the local population. Natal is a city where the ambient qualities are well defined and known by the beauty of the area where it is located. Situated just between a river and the sea, the city grew following its geographic characteristics. The Potengi River, the Atlantic Ocean and the vast dunes ecosystem represented natural limits to the urban expansion; at the same time they have favored the development of a landscape pattern marked by the dialectic between the natural elements and the human interventions. However, this relationship changed after the intensification of the high rising development process that took place since the 1960s. The urban legislation tried to preserve the features of the local landscape delimiting Areas for Controlling Building High , destined to protect the scenic value of some parts of the city. On the other hand, the civil construction sector has made constant pressure in sense to abolish or to modify this legal instrument, aiming profits that have increased, in the 1990s, because of the consumption and the qualification of the urban space for tourist activities. It is necessary the raising of new elements to stimulate the quarrel about the landscape preservation, the process of the urban space production and the best way for the legislation implementation. This work tries to raise elements about the subject at local level, in sense to use Natal City experience to contribute for the formulation of indicators to raise the question about the lack of measure for subjective values, for example the cultural and affective value of the landscape. The natural elements inserted in the urban profile, represent strong visual references and supply identity to the town; they are part of the collective imaginary and are detached in the social context of the city. Then, why the preservation of the landscape, that estimates the improvement in the quality of life, is not enough to justify the controlling building high already previewed as part of Natal City Legislation? These questions send us to the approach of the landscape, as a community patrimony, alerting that some of its significant esthetics attributes must be preserved as a legacy for the future generations

De lettre intime à lettre ouverte dans Lettres à l’Indigène de Joël Des Rosiers

Dans la première décennie du XXIe siècle, à l’ère des nouvelles technologies de communication électroniques, le courriel est devenu le moyen par excellence pour envoyer et recevoir du contenu privé, remplaçant dès lors l’envoi de lettres papier. Dans ce contexte, pour quelles raisons un individu souhaiterait-il partager ce contenu privé en le publiant ouvertement, publiquement, de plus, dans un format papier, le rendant désormais disponible à l’ensemble des lecteurs désirant en consulter le contenu? Pourtant, telle est la genèse du recueil Lettres à l’Indigène de Joël Des Rosiers dans lequel l’auteur fait don de lettres d’amour qui « deviennent alors des objets communs que partagent la destinataire et l’homme qui lui écrit, le livre et le lecteur » (LALI, p. 7). Ainsi, c’est par la réappropriation d’une pratique épistolaire ancienne que cet ouvrage rend compte d’une écriture intimiste dans laquelle lettres intimes et lettres ouvertes se côtoient. Les lettres intimes comportent plusieurs ressemblances avec les lettres conventionnelles, mais s’en distinguent sur certains points. Les lettres ouvertes, quant à elles, s’apparentent davantage aux publications libres que l’on retrouve dans les divers périodiques papier ou Web, ainsi que dans les divers blogues. Dans les deux types de lettres, nous voyons quelle est la place du destinateur et celle de l’Autre, nous présentons les différentes constructions de l’espace liées à chacune des formes de lettre et nous dévoilons les diverses stratégies formelles qui laissent voir un jeu entre les sphères publique et privée. Nous démontrons ainsi de quelles manières ce recueil questionne l’intimisme du XXIe siècle, ainsi que la pratique d’une écriture intimiste dans le cadre actuel.

Improved Electronics for the Hall A Detectors at JLab: Summing Modules and VDC Amplifier/Discriminator Cards

Testing of summing electronics and VDC A/D Cards was performed to assure proper functioning and operation within defined parameters. In both the summing modules and the VDC A/D cards, testing for minimum threshold voltage for each channel and crosstalk between neighboring channels was performed. Additionally, the modules were installed in Hall A with input signals from shower detectors arranged to establish a trigger by summing signals together with the use of tested modules. Testing involved utilizing a pulser to mimic PMT signals, a discriminator, an attenuator, a scaler, a level translator, an oscilloscope, a high voltage power supply, and a special apparatus used to power and send signal to the A/D cards. After testing, modules were obtained that meet necessary criteria for use in the APEX experiment, and the A/D cards obtained were determined to have adequate specifications for their utilization, with specific results included in the appendix.

The Influence of HOPE VI Public Housing on Public Schools

In the United States, public school enrollment is typically organized by neighborhood boundaries. This dissertation examines whether the federally funded HOPE VI program influenced performance in neighborhood public schools. In effect since 1992, HOPE VI has sought to revitalize distressed public housing using the New Urbanism model of mixed income communities. There are 165 such HOPE VI projects nationwide. Despite nearly two decades of the program’s implementation, the literature on its connection to public school performance is thin. My dissertation aims to narrow this research gap. There are three principal research questions: (1) Following HOPE VI, was there a change in socioeconomic status (SES) in the neighborhood public school? The hypothesis is that low SES (measured as the proportion of students qualifying for the Free and Reduced Lunch Program) would reduce. (2) Following HOPE VI, did the performance of neighborhood public schools change? The hypothesis is that the school performance, measured by the proportion of 5th grade students proficient in state wide math and reading tests, would increase. (3) What factors relate to the performance of public schools in HOPE VI communities? The focus is on non-school, neighborhood factors that influence the public school performance. For answering the first two questions, I used t-tests and regression models to test the hypotheses. The analysis shows that there is no statistically significant change in SES following HOPE VI. However, there are statistically significant increases in performance for reading and math proficiency. The results are interesting in indicating that HOPE VI neighborhood improvement may have some relationship with improving school performance. To answer the third question, I conducted a case study analysis of two HOPE VI neighborhood public schools, one which improved significantly (in Philadelphia) and one which declined the most (in Washington DC). The analysis revealed three insights into neighborhood factors for improved school performance: (i) a strong local community organization; (ii) local community’s commitment (including the middle income families) to send children to the public school; and (iii) ties between housing and education officials to implement the federal housing program. In essence, the study reveals how housing policy is de facto education policy.
