    An ethnomethodological approach to examine exploitation in the context of capacity, trust and experience of commercial surrogacy in India

    No full text
    The socio-ethical concerns regarding exploitation in commercial surrogacy are premised on asymmetric vulnerability and the commercialization of women’s reproductive capacity to suit individualistic motives. In examining the exploitation argument, this article reviews the social contract theory that describes an individual as an ‘economic man’ with moral and/or political motivations to satisfy individual desires. This study considers the critique by feminists, who argue that patriarchal and medical control prevails in the surrogacy contracts. It also explores the exploitative dynamics amongst actors in the light of Baier’s conceptualization of trust and human relationship, within which both justice and exploitation thrive, and Foucault’s concept of bio-power. Drawing on these concepts, this paper aims to investigate the manifestations of exploitation in commercial surrogacy in the context of trust, power and experiences of actors, using a case study of one clinic in India. The actors’ experiences are evaluated at different stages of the surrogacy process: recruitment, medical procedures, living in the surrogate home, bonding with the child and amongst actors, financial dealings, relinquishment and post-relinquishment.This study applies ethnomethodology to identify phenomena as perceived by the actors in a situation, giving importance to their interpretations of the rules that make collective activity possible. The methods include semi-structured interviews, discussions, participant observation and explanation of the phenomena from the actors’ perspectives. Between August 2009 and April 2010, 13 surrogate mothers (SMs), 4 intended parents (IPs) and 2 medical practitioners (MPs) from one clinic in Western India were interviewed.This study reveals that asymmetries of capacity amongst the MPs, SMs, IPs and surrogate agents (SAs) lead to a network of trust and designation of powers through rules, bringing out the relevance of Baier’s conceptualization of asymmetric vulnerability, trust and potential exploitation in human relationships. The IPs are exploited, especially in monetary terms. The SMs are relatively the most exploited, given their vulnerability. Their remuneration through surrogacy is significant for them, and their acquired knowledge as ex-surrogates is used for their own benefit and for exploiting others. Foucault’s conceptualization of power is hence relevant, since the ex-SMs re-invest the power of their exploitative experience in exploiting others

    Vibration control of a flexible structure using electromagnetic dampers

    No full text
    This thesis presents both theoretical and experimental studies aimed at reducing vibrations in flexible structures using an electromagnetic damper. In recent years, semiactive vibration control systems have gained importance due to their ability to balance between effective vibration control and energy consumption compared to active control systems. Consequently, this research begins by exploring semiactive control strategies for the vibration control of the flexible structures. A comprehensive investigation is conducted on vibration control of a SDOF structure using passive, active and semiactive control strategies. The effectiveness of each method is evaluated and compared. The passive and active control methods are introduced and compared with semiactive time-varying on-off control strategies. Numerical simulation demonstrates that the semi-active control provides better damping compared to the passive damping, although less effective than active control. In addition, the reviews of various active dampers such as magneto-rheological (MR) piezoelectric and electromagnetic dampers based on their ability to alter mechanical properties in response to external stimuli. The electromagnetic (EM) damper is the primary focus of this work, and its dynamic characterisation experimentally determined, confirming its potential for both active and semiactive control application.The thesis further investigates the passive vibration control capabilities of an electromagnetic damper shunted damper with various RLC network. An analytical approach is used to evaluate the damping effects of purely resistive, RL and RLC shunt configuration. The optimal resistance values are evaluated using root locus method. The study extended by integrating the electromagnetic damper into primary structure- a cantilever beam modelled as SDOF system, where the EM damper functions as passive tuned mass damper under open circuit condition. While the passive TMDs are effective at suppressing vibration at specific resonant frequency that are limited to narrow bandwidth. To overcome this limitation, an electromagnetic damper tuned to the structural frequency is designed and evaluated. The performance of the tuned EM-TMD is compared with that of the conventional TMD, demonstrating enhanced vibration attenuation and improved adaptability. The final part of the thesis focuses on active vibration control using electromagnetic dampers. The commonly used direct velocity feedback (DVF) control is implemented and evaluated. While DVF is effective at the fundamental resonant frequency, it offer limited suppression at other frequencies. To over this limitation, proportional resonant (PR) control is proposed and investigated. The PR control effectively reduces the vibration at resonance and can be tuned to specific resonant frequencies. For numerical investigation, the beam is modelled as an SDOF structure. The vibration reduction performance of the PR controller is assessed for the various values of proportional gain, resonant gain, and damping ratio. Both time domain and frequency domain analysis are carried out, and the result shoes that the PR controller outperforms the conventional DVF control at the target resonance frequency. In addition to numerical analysis, experimental validation is carried out using a cantilever beam equipped with an EM damper. The continuous-time PR controller is implemented on the dSPACE controller using its discrete-time equivalent. The experimental confirms the trend observed in the numerical analysis. The DVF control is also implemented experimentally to benchmark the performance of both strategies. Finally, the multimodal vibration control is achieved by placing multiple PR controllers in parallel, each tuned to distinct resonant mode. The experimental result shows that the proposed PR control strategy provides superior vibration suppression compared to the traditional direct velocity feedback control, especially for multi-mode vibration scenarios.<br/

    Global justice, capabilities approach and commercial surrogacy in India

    No full text
    Inequalities, ineffective governance, unclear surrogacy regulations and unethical practices make India an ideal environment for global injustice in the process of commercial surrogacy. This article aims to apply the 'capabilities approach' to find possibilities of global justice through human fellowship in the context of commercial surrogacy. I draw primarily on my research findings supplemented by other relevant empirical research and documentary films on surrogacy. The paper reveals inequalities and inadequate basic entitlements among surrogate mothers as a consequence of which they are engaged in unjust contracts. Their limited entitlements also limit their opportunities to engage in enriching goals. It is the role of the state to provide all its citizens with basic entitlements and protect their basic human rights. Individuals in India evading their basic duty also contribute to the existing inequalities. Individual responsibilities of the medical practitioners and the intended parents are in question here as they are more inclined towards self-interest rather than commitment towards human fellowship. At the global level, the injustice in transnational commercial surrogacy practices in developing countries calls for an international declaration of women and child rights in third party reproduction with a normative vision of mutual fellowship and human dignity
