This dissertation examines the ideological connections between schooling, mobility, and social difference among students in New Delhi. In it, I argue that educational mobility, especially with regard to English-language education, is an ideology which seems to offer a path to reduce social difference while in fact protecting it. I also argue that people who desire mobility engage in discursive practices which attempt to emphasize how their social positions are better than the ones they aspire to, a process I call discursive mobility. These discourses are inherently conflicted and contradictory, something I argue is characteristic of discursive responses to ideologies of educational mobility. Thus, I inquire into how different ideologies and discourses (dominant and subordinate) relating to social difference, education, and mobility interact, the prominent role of English in ideologies of education and mobility, and how the process of attempting mobility produces inherently contradictory ways of being. This research was conducted in two government schools and one private school in New Delhi, using a number of methods including participant observation, surveys, interviews, group discussions, and matched guise technique. I describe the discursive contradictions that come from attempts at discursive mobility, how language is implicated in ideologies of educational mobility, how social ideologies of privilege affect schooling experiences and mobility possibilities, how students discursively respond to social difference, and how the discursive worlds of students in government and private schools differ.

Doctor of Philosophy (Ph.D.) / The buzzword of this decade has been convergence: the convergence of telecommunications, Internet, entertainment, and information technologies for the seamless provisioning of multimedia services across different network types. Thus the future Next Generation Mobile Network (NGMN) can be envisioned as a group of co-existing heterogeneous mobile data networking technologies sharing a common Internet Protocol (IP) based backbone. In such all-IP based heterogeneous networking environments, ongoing sessions from roaming users are subjected to frequent vertical handoffs across network boundaries. Therefore, ensuring uninterrupted service continuity during session handoffs requires successful mobility and session management mechanisms to be implemented in these participating access networks. Therefore, it is essential for a common interworking framework to be in place for ensuring seamless service continuity over dissimilar networks to enable a potential user to freely roam from one network to another. For the best of our knowledge, the need for a suitable unified mobility and session management framework for the NGMN has not been successfully addressed as yet. This can be seen as the primary motivation of this research. Therefore, the key objectives of this thesis can be stated as:  To propose a mobility-aware novel architecture for interworking between heterogeneous mobile data networks  To propose a framework for facilitating unified real-time session management (inclusive of session establishment and seamless session handoff) across these different networks. In order to achieve the above goals, an interworking architecture is designed by incorporating the IP Multimedia Subsystem (IMS) as the coupling mediator between dissipate mobile data networking technologies. Subsequently, two different mobility management frameworks are proposed and implemented over the initial interworking architectural design. The first mobility management framework is fully handled by the IMS at the Application Layer. This framework is primarily dependant on the IMS’s default session management protocol, which is the Session Initiation Protocol (SIP). The second framework is a combined method based on SIP and the Mobile IP (MIP) protocols, which is essentially operated at the Network Layer. An analytical model is derived for evaluating the proposed scheme for analyzing the network Quality of Service (QoS) metrics and measures involved in session mobility management for the proposed mobility management frameworks. More precisely, these analyzed QoS metrics include vertical handoff delay, transient packet loss, jitter, and signaling overhead/cost. The results of the QoS analysis indicates that a MIP-SIP based mobility management framework performs better than its predecessor, the Pure-SIP based mobility management method. Also, the analysis results indicate that the QoS performances for the investigated parameters are within acceptable levels for real-time VoIP conversations. An OPNET based simulation platform is also used for modeling the proposed mobility management frameworks. All simulated scenarios prove to be capable of performing successful VoIP session handoffs between dissimilar networks whilst maintaining acceptable QoS levels. Lastly, based on the findings, the contributions made by this thesis can be summarized as:  The development of a novel framework for interworked heterogeneous mobile data networks in a NGMN environment.  The final design conveniently enables 3G cellular technologies (such as the Universal Mobile Telecommunications Systems (UMTS) or Code Division Multiple Access 2000 (CDMA2000) type systems), Wireless Local Area Networking (WLAN) technologies, and Wireless Metropolitan Area Networking (WMAN) technologies (e.g., Broadband Wireless Access (BWA) systems such as WiMAX) to interwork under a common signaling platform.  The introduction of a novel unified/centralized mobility and session management platform by exploiting the IMS as a universal coupling mediator for real-time session negotiation and management.  This enables a roaming user to seamlessly handoff sessions between different heterogeneous networks.  As secondary outcomes of this thesis, an analytical framework and an OPNET simulation framework are developed for analyzing vertical handoff performance. This OPNET simulation platform is suitable for commercial use.

This thesis progressively evolves and presents a practical 'theory' for mobile work – mobile trajectory – through three case studies conducted using fieldwork. The three cases presented here examine tram travellers finding their way around a city centre (Case A), health care workers looking after people with mental illness in a residential setting (Case B) and mobile clinicians caring for young people with mental illness in a community setting (Case C). My concern is to develop a 'theory' for mobile work that is both practical and theoretical,; at once supporting the practical action of completing field and analytic work while abstracting away from the ordinary affairs of society. The contribution of this ‘theory’ is to synthesise ideas from the domain of studies of ICTs mobile work to support description, rhetoric, inference and application for mobile work. This 'theory' has particular COMPONENTS, FEATURES, PROPERTIES, CONCERNS and ASSOCIATED NOTIONS. / A mobile trajectory has a CORE TRAJECTORY that involves particular work: the CORE WORK. There are ALIGNED TRAJECTORIES that feed the CORE TRAJECTORY. These are part of the CORE TRAJECTORY. The FEATURES of mobile trajectory are CYCLES, TRANSITIONS, TRAVERSALS, STREAMS, SCHEMES, POSSIBILITIES, HISTORICITY and SHAPE. The PROPERTIES are PHYSICALITY, LOCALITY, INSTRUMENTALITY, SYNCHRONICITY, INTER- DEPENDENCY, PREDICTABILITY and PALPABILITY. Important CONCERNS are RECONCILIATION CONCERNS, ALIGNMNENT CONCERNS, RECIPROCAL CONCERNS and CONTINGENCY CONCERNS. Key ASSOCIATED NOTIONS are SOCIAL SPHERES with particular WORLDS and SUB-WORLDS comprising MEMBERS with particular ROLES and INVOLVEMENT. SOCIAL SPHERES have particular BOUNDARIES, RESOURCES and MEDIA and shared KNOWLEDGE and PRACTICES. MEDIA and RESOURCES have particular AVAILABILITY and MUTABILITY. MEMBERS have particular BIOGRAPHIES, TIES and OBLIGATIONS and AWARENESS of others. Through the case material presented I demonstrate how this 'theory' supports the work of describing and discussing mobile work for the purpose of conceptualising, selecting, recommending and critically evaluating everyday Information and Communication Technologies. At the end of the thesis I compare mobile trajectory to three alternative approaches and two alternative theories with regard to supporting the same kind of work.

As China develops and progresses as a nation, unique patterns of social mobility are emerging. For many years a centrally planned economy, the country is now a hybrid economy characterised by its authoritative political structure while allowing its entrepreneurs to experiment with innovative ways to accumulate wealth and ‘get ahead’. The research is particularly interested and aims in understanding how a specific group of people, namely the home-grown entrepreneurs, have been able to achieve social mobility within the contemporary Chinese economy. It focuses on the city of Suzhou in Jiangsu Province. Suzhou was chosen as the research setting because, since the beginning of the 1980s, it has been rapidly transformed into a business and industrial centre by implementation of economic reforms shaped by Deng Xiaoping and the production of infrastructure, such as the Economic and Technological Development Zones, from Communist Party initiatives. Home-grown entrepreneurs were ready to take advantage of the booming business opportunities by using their personal resources and networks afforded by the economic reforms that introduced foreign direct investment to coincide with private business reform. Specifically, it examines how the economic reforms have fostered conditions that allowed home-grown entrepreneurs to emerge and prosper and, in turn, how these entrepreneurs cultivate and utilise their social capital to form strategies to create pathways leading to social mobility. Qualitative research uncovers the social mobility of these entrepreneurs by interviewing in-depth a total of 50 home-grown entrepreneurs from different generations currently operating in Suzhou. The research reveals that while the economic reforms did provide a favourable environment for conducting private businesses, it has been equally important for each generation of home-grown entrepreneurs to take specific risks and seize opportunities to acquire various forms of social capital and to adjust personal values and imposed goals to reflect the complex social and political dynamics of their times. They had to make appropriate decisions to consolidate their businesses through careful consideration and manipulation of a variety of social capital. While social mobility may seem more accessible under the new hybrid economy, business failures and growing social inequalities have not been uncommon. Data analysis provides insights to conclude that the research may construct a new normative theory about a value driven society with economic aspirations within social controls constructed by authoritarian capitalism. As home-grown entrepreneurs begin to dominate, they are not only redefining how various forms of social capital should be linked to trajectories for social mobility, increasingly they are also transforming the social landscapes of China’s business world.

<p>The purpose of this study is to examine what effect social background may have on the timing of becoming a parent in Sweden. By applying event-history techniques to data from the Swedish level of living survey (LNU) we try to separate the direct from the indirect effect of social background on timing of first childbearing. Few previous studies have focused on characteristics of social background and analysis of intergenerational effects on the age of becoming a parent. In this study, we show that the risk of becoming a parent is different for those who are mobile than for the socially non-mobile. The effect of social background on the propensity of becoming a parent is not just indirect via persons own educational careers. When we control for own educational level much of the impact of social background on the propensity of becoming a parent remains. We clearly show the existence of a significant direct effect of social background on the propensity to become a parent.</p>

Biaxial tensile strained Si grown on SiGe virtual substrates will be incorporated into future generations of CMOS technology due to the lack of performance increase with scaling. Compressively strained Ge-rich alloys with high hole mobilities can also be grown on relaxed SiGe. We review progress in strained Si and dual channel heterostructures, and also introduce high hole mobility digital alloy heterostructures. By optimizing growth conditions and understanding the physics of hole and electron transport in these devices, we have fabricated nearly symmetric mobility p- and n-MOSFETs on a common Si₀.₅Ge₀.₅ virtual substrate. / Singapore-MIT Alliance (SMA)
