The adoption and use of SMS among Chinese teenagers

Ce mémoire examine l'adoption des téléphones mobiles et l'utilisation des messages texte (SMS) par les adolescents chinois, selon la théorie des usages et gratifications et de la recherche sur la communication par ordinateur. Certains champs particuliers de l'utilisation des messages textes par les adolescents chinois, comme le contrôle parental, la circulation des chaînes de messages, la popularité des messages de salutations et l'utilisation répandue des émoticônes ont été étudiés. La fonction sociale des SMS, plus particulièrement des pratiques sociales et des relations émotionnelles des adolescents chinois, a également été explorée. Cette étude est basée sur un sondage réalisé sur le terrain auprès de 100 adolescents chinois. Elle révèle que chez les adolescents chinois, les deux principales raisons pour l'adoption du téléphone mobile sont l'influence parentale et le besoin de communication sociale. Quant à l'utilisation des messages texte, elle répond à sept usages et gratifications : la flexibilité, le coût modique, l’intimité, éviter l'embarras, le divertissement, l'engouement et l'évasion. Il a également été observé que les messages texte jouent un rôle positif dans la construction et l'entretien des relations sociales des adolescents chinois.

The Educational Experience of Students of Chinese Origin in a French-Speaking Context : the role of school, family, and community

Cette recherche vise à documenter l’expérience scolaire des élèves québécois d’origine chinoise à l’école secondaire de langue française et à examiner les dynamiques qui influencent la réussite scolaire de ces élèves. Elle s’intéresse plus précisément aux impacts des facteurs relatifs à l’école, à la famille immigrante, et à ceux de la communauté ethnique sur l’intégration de ces jeunes dans un contexte francophone. Les données ont été principalement recueillies à travers des entretiens semi-structurés approfondis auprès d’élèves d’origine chinoise et de différents acteurs du paradigme éducatif (parents, acteurs scolaires et intervenants communautaires). D’autres instruments, tels que l’analyse du contenu de documents et de médias, ont également été utilisés afin de fournir des informations contextuelles et d’enrichir les données d’entrevues. Les données ont été analysées selon un cadre théorique ouvert et inclusif où la réussite scolaire des élèves issus de l’immigration est mesurée en mettant l’accent sur l’influence de la maîtrise de la langue d’enseignement, du capital culturel et social de la famille et de la communauté immigrante, ainsi que des facteurs systémiques au niveau de l’école. Les résultats de cette étude dans trois écoles cibles montrent qu’en général les élèves d’origine chinoise connaissent une expérience positive, surtout en ce qui concerne leur performance scolaire en mathématiques et sciences. Cependant, les nouveaux arrivants ont tendance à éprouver des difficultés dans l’apprentissage du français et pour leur intégration sociale. En effet, le processus d’intégration socioscolaire des jeunes chinois est sous l’influence des différents milieux qu’ils fréquentent. À propos de l’influence des dynamiques scolaires, les résultats de la recherche indiquent qu’une relation maître-élève positive joue un rôle important dans la réussite éducative de ces élèves. Toutefois, l’insuffisance du soutien à l’apprentissage défavorise l’intégration linguistique et sociale des élèves nouvellement arrivés. Les données de cette étude soulignent notamment le rôle de la famille immigrante et de la communauté ethnique dans l’expérience scolaire de ces jeunes. D’une part, sous l’impact des dynamiques familiales, notamment ce qui à trait au projet migratoire, à la culture chinoise et à l’expérience pré- et post-migratoire, les parents immigrants chinois s’impliquent activement dans les études de leurs enfants, malgré des barrières linguistiques et culturelles. D’autre part, afin de surmonter les effets négatifs des faibles liens entretenus avec l’école de langue française, les parents chinois ont largement recours aux ressources au sein de la communauté ethnique, tels que les médias de langue chinoise, les organismes ethnospécifiques de services aux immigrants, l’école du samedi et les institutions religieuses ethniques. Ces institutions sociales ethniques contribuent à soutenir les valeurs culturelles, échanger des informations, établir des modèles pour les jeunes et à fournir des services appropriés en matière culturelle et linguistique.

Interprovincial migration among chinese skilled worker immigrants to Quebec.

The purpose of this research is to find out whether higher levels of education cause the exodus of Quebec’s Chinese skilled worker immigrants to other provinces. I first examine the history of Chinese immigration in Canada; the federal and Quebec’s immigration policies and selection criteria, as well as statistics regarding Chinese migration to Quebec and their out- migration from the province. My study’s ethnographic findings suggest that higher levels of education are not the main cause of the exodus, nor is the lack of French language competence. Rather, kin ties, age, and marital status play an influential role on interprovincial-migration of Quebec’s Chinese skilled immigrants. While based on a small number of respondents, my study indicates that having personal networks in Quebec before immigration tends to retain immigrants in the province.

Analyse géographique des investissements internationaux de la China National Petroleum Corporation

Ce mémoire propose une analyse de l’expansion internationale de la China National Petroleum Corporation (CNPC) et des impacts de cette expansion sur la sécurité énergétique de la Chine. Dans le cadre de cette recherche, l’approvisionnement énergétique d’un pays est jugé sécuritaire lorsqu’une quantité suffisante de ressources nécessaires pour combler sa demande en énergie sont présentes, disponibles et accessibles et que son approvisionnement en services énergétiques demeure fiable et abordable. La recherche comporte quatre volets. Le premier volet porte sur les étapes de la restructuration de l’industrie pétrolière chinoise depuis 1949. Celle-ci est analysée au travers des changements dans les modes de gestion des compagnies pétrolières nationales et dans leurs relations avec le gouvernement chinois. Le deuxième volet traite de la diversification et des nouvelles spécialisations de CNPC. Ces aspects sont étudiés dans le cadre d’une analyse du pourcentage de ses actifs dans chaque segment industriel (aval, intermédiaire et amont) obtenus grâce à ses rapports annuels. Le troisième volet aborde la répartition géographique des activités de la compagnie que l’on étudie à l’aide d’une analyse approfondie de près de 150 investissements, acquisitions et contrats réalisés à l’étranger entre 1992 et 2014. Le quatrième volet aborde les impacts des investissements à l’étranger de la compagnie sur la sécurité énergétique de la Chine. Ces impacts sont mesurés par l’entremise d’une analyse des flux pétroliers internationaux vers la Chine que l’on compare à la production de CNPC par pays. Ce mémoire permet de déterminer que l’expansion internationale de CNPC sert d’abord et avant tout les intérêts économiques de la compagnie. Ce sont surtout ses investissements dans la construction d’infrastructures de transport (oléoducs, gazoducs ainsi que les usines et terminaux de liquéfaction de gaz naturel liquéfié) qui apportent des bénéfices directs à la sécurité énergétique de la Chine. La contribution des investissements dans les autres secteurs est beaucoup moins systématique et dépend largement de la période au cours de laquelle ils ont été effectués.

The empirical study of the price mechanism in the Chinese housing market

In China, the history of the establishment of the private housing market is pretty short. Actually in less then two decades, the market has grown from almost the scratch to playing an important role in the economy. A great achievement! But many problems also exist. They need to be properly addressed and solved. Price problem---simply put, housing price is too high--- is one of them, and this paper is focused on it. Three basic questions are posed, i.e. (1) how to judge the housing affordability? (2) why the housing price is so high? (3) how to solve the housing price problem. The paper pays particular attention to answering the second question. Except the numerous news reports and surveys show that most of the ordinary city dwellers complained about the high housing price, the mathematical means, the four ratios, are applied to judge the housing affordability in Shanghai and Shenzhen. The results are very clear that the price problem is severe. So why? Something is wrong with the price mechanism. This research shows that mainly these five factors contribute to the price problem: the housing reform, the housing development model, the unbalanced housing market, the housing project financing and the poor governmental management. Finally the paper puts forward five suggestions to solve the housing price problem in first-hand private Chinese housing market. They include: the establishment of real estate information system, the creation of specific price management department, the government price regulation, the property tax and the legalization of "cushion money".

A Study of a Comprehensive Career Services System in Chinese Universities

Since 1999, with the adoption of expansion policy in higher education by the Chinese government, enrollment and graduate numbers have been increasing at an unprecedented speed. Accustomed to a system in which university graduates were placed, many students are not trained in “selling themselves”, which exacerbates the situation leading to a skyrocketing unemployment rate among new graduates. The idea of emphasizing career services comes with increasing employment pressure among university graduates in recent years. The 1998 “Higher Education Act” made it a legislative requirement. Thereafter, the Ministry of Education issued a series of documents in order to promote the development of career services. All higher education institutions are required to set up special career service centers and to set a ratio of 1:500 between career staff and the total number of students. Related career management courses, especially career planning classes, are required to be clearly included as specific modules into the teaching plan with a requirement of no less than 38 sessions in one semester at all universities. Developing career services in higher education has thus become a hot issue. One of the more notable trends in higher education in recent years has been the transformation of university career service centers from merely being the coordinators of on-campus placement into full service centers for international career development. The traditional core of career services in higher education had been built around guidance, information and placements (Watts, 1997). This core was still in place, but the role of higher education career services has changed considerably in recent years and the nature of each part is being transformed (Watts, 1997). Most services are undertaking a range of additional activities, and the career guidance issue is emphasized much more than before. Career management courses, especially career planning classes, are given special focus in developing career services in the Chinese case. This links career services clearly and directly with the course provision function. In China, most career service centers are engaging in the transformation period from a “management-oriented” organization to a “service-oriented” organization. Besides guidance services, information services and placement activities, there is a need to blend them together with the new additional teaching function, which follows the general trend as regulated by the government. The role of career services has been expanding and this has brought more challenges to its development in Chinese higher education. Chinese universities still remain in the period of exploration and establishment in developing their own career services. In the face of the new situation, it is very important and meaningful to explore and establish a comprehensive career services system to address student needs in the universities. A key part in developing this system is the introduction of career courses and delivering related career management skills to the students. So there is the need to restructure the career service sectors within the Chinese universities in general. The career service centers will operate as a hub and function as a spoke in the wheel of this model system, providing support and information to staff located in individual teaching departments who are responsible for the delivery of career education, information, advice and guidance. The career service centers will also provide training and career planning classes. The purpose of establishing a comprehensive career services system is to provide a strong base for student career development. The students can prepare themselves well in psychology, ideology and ability before employment with the assistance of effective career services. To conclude, according to the different characteristics and needs of students, there will be appropriate services and guidance in different stages and different ways. In other words, related career services and career guidance activities would be started for newly enrolled freshmen and continue throughout their whole university process. For the operation of a comprehensive services system, there is a need for strong support by the government in the form of macro-control and policy guarantee, but support by the government in the form of macro-control and policy guarantee, but also a need for close cooperation with the academic administration and faculties to be actively involved in career planning and employment programs. As an integral function within the universities, career services must develop and maintain productive relationships with relevant campus offices and key stakeholders both within the universities and externally.

Political Economy of Global Rush for Agricultural Land: a Tract on India’s Overseas Acquisitions

This paper is an attempt to map the global land acquisitions with a focus on Indian MNCs in acquiring overseas land for agricultural purposes. It tries to outline the contemporary political economy of capital accumulation at the global level, especially, in the emerging developing economies like India and China, where the emergence of a new capitalist class has engaged itself into acquisition of land and control of other natural resources in Africa, Latin America, Eastern Europe and South East Asia, for example, water and other minerals to secure itself from the eventual losses of ongoing economic crisis and to earn profit from the volatile agricultural commodity markets. This sway of control of resources by the MNCs has got paramount State support under the helm of neoliberal policies. The paper provides scale of overseas land acquisitions at the current juncture and tries to highlight its causes and the major implications associated with it.

How do consumers perceive organic food from different geographic origins? Evidence from Hong Kong and Shanghai

The objective of this paper is to understand how Chinese consumers perceive certified organic food, especially the differences between locally and nationally produced organic food compared to food produced overseas. In 2012, a consumer survey was conducted at supermarkets in Hong Kong and Shanghai (N=245). Participants were asked for their perception on four different food origins: locally produced organic food, organic food from China, imported organic food, and locally produced conventional food. Consumers in Hong Kong had a positive attitude towards local organic food and imported organic food. However, they were sceptical about organic food from China, in particular regarding chemical residues and the trustworthiness of producers. Consumers in Shanghai, in contrast, had a positive attitude towards all three tested geographical origins of organic food. Overall, the results suggest that it is challenging for marketers to promote and boost the sales of China-produced organic food in China. Better communication is essential to convince consumers that organic food from China is of similar quality as organic food produced elsewhere.

Cell-line Engineering of Chinese Hamster Ovary Cells for Low-temperature Culture

Developments in mammalian cell culture and recombinant technology has allowed for the production of recombinant proteins for use as human therapeutics. Mammalian cell culture is typically operated at the physiological temperature of 37°. However, recent research has shown that the use of low-temperature conditions (30-33°) as a platform for cell-culture results in changes in cell characteristics, such as increased specific productivity and extended periods of cell viability, that can potentially improve the production of recombinant proteins. Furthermore, many recent reports have focused on investigating low-temperature mammalian cell culture of Chinese hamster ovary (CHO) cells, one of the principal cell-lines used in industrial production of recombinant proteins. Exposure to low ambient temperatures exerts an external stress on all living cells, and elicits a cellular response. This cold-stress response has been observed in bacteria, plants and mammals, and is regulated at the gene level. The exact genes and molecular mechanisms involved in the cold-stress response in prokaryotes and plants have been well studied. There are also various reports that detail the modification of cold-stress genes to improve the characteristics of bacteria or plant cells at low temperatures. However, there is very limited information on mammalian cold-stress genes or the related pathways governing the mammalian cold-stress response. This project seeks to investigate and characterise cold-stress genes that are differentially expressed during low-temperature culture of CHO cells, and to relate them to the various changes in cell characteristics observed in low-temperature culture of CHO cells. The gene information can then be used to modify CHO cell-lines for improved performance in the production of recombinant proteins.

Over Expression of the CMP-sialic Acid Transporter in Chinese Hamster Ovary Cells Leads to Increased Sialylation

Most glyco-engineering approaches used to improve quality of recombinant glycoproteins involve the manipulation of glycosyltransferase and/or glycosidase expression. We investigated whether the over expression of nucleotide sugar transporters, particularly the CMP-sialic acid transporter (CMP-SAT), would be a means to improve the sialylation process in CHO cells. We hypothesized that increasing the expression of the CMP-SAT in the cells would increase the transport of the CMP-sialic acid in the Golgi lumen, hence increasing the intra-lumenal CMP-sialic acid pool, and resulting in a possible increase in sialylation extent of proteins being produced. We report the construction of a CMP-SAT expression vector which was used for transfection into CHO-IFNγ, a CHO cell line producing human IFNγ. This resulted in approximately 2 to 5 times increase in total CMP-SAT expression in some of the positive clones as compared to untransfected CHO-IFNγ, as determined using real-time PCR analysis. This in turn concurred with a 9.6% to 16.3% percent increase in site sialylation. This engineering approach has thus been identified as a novel means of improving sialylation in recombinant glycoprotein therapeutics. This strategy can be utilized feasibly on its own, or in combination with existing sialylation improvement strategies. It is believed that such multi-prong approaches are required to effectively manipulate the complex sialylation process, so as to bring us closer to the goal of producing recombinant glycoproteins of high and consistent sialylation from mammalian cells.

Variability in the Stability and Productivity of Transfected Genes in Chinese Hamster Ovary (CHO) cells

In the field of biologics production, productivity and stability of the transfected gene of interest are two very important attributes that dictate if a production process is viable. To further understand and improve these two traits, we would need to further our understanding of the factors affecting them. These would include integration site of the gene, gene copy number, cell phenotypic variation and cell environment. As these factors play different parts in the development process, they lead to variable productivity and stability of the transfected gene between clones, the well-known phenomenon of “clonal variation”. A study of this phenomenon and how the various factors contribute to it will thus shed light on strategies to improve productivity and stability in the production cell line. Of the four factors, the site of gene integration appears to be one of the most important. Hence, it is proposed that work is done on studying how different integration sites affect the productivity and stability of transfected genes in the development process. For the study to be more industrially relevant, it is proposed that the Chinese Hamster Ovary dhfr-deficient cell line, CHO-DG44, is used as the model system.

Implicaciones comerciales de la Diplomacia Petrolera China en el Amazonas ecuatoriano. 2007 - 2013

El presente Estudio de Caso tiene como objetivo analizar en qué medida las dinámicas comerciales de la Diplomacia Petrolera China han convertido a Ecuador en un socio estratégico para la RPCh. El petróleo como fuente de energía es primordial para llevar a cabo los procesos de industrialización y mantener el crecimiento económico del león Asiático. Por eso su búsqueda se ha convertido en un tema principal dentro de la agenda de política exterior. Ecuador, el tercer país de Suramérica con más reservas de petróleo, después de Venezuela y Brasil, se ha convertido en zona de influencia de la RPCh y a través de las empresas petroleras estatales se han firmado contratos por la venta de petróleo. A pesar de que las relaciones bilaterales son asimétricas, se buscar establecer si Ecuador es un socio estratégico en la región.
