There has been a fundamental change in health care pedagogy to address the demands and challenges posed by the present generation of millennial students. There is also a growing recognition of the role of intrinsic motivation as a catalyst in a positive learning experience. The term intrinsic motivation refers to energizing behavior that comes from within an individual and develops due to an inherent interest in the activity at hand. However, stimulating intrinsic motivation in the present generation of millennial health care students is a daunting task, considering their diverse and disparate nature. In addition, the inherent generational differences between educators and students, and an increasing emphasis on technological tools have resulted in a dichotomy in the educational environment leading to the development of a greater incidence of burnouts among students. Hence, numerous innovative techniques have been introduced in health care education to enhance the levels of intrinsic motivation in these students. Unfortunately, most of these approaches have only been moderately successful due to their limited ability to address the unique educational expectations of millennial students. The cumulative evidence suggests that specific approaches to stimulate intrinsic motivation should aim at nurturing the learning efforts of students, bridging the generational barriers between educators and students, and ameliorating the stress associated with health care education. Hence, the specific aim of this narrative review is to suggest empirically proven curricular strategies and institutional reforms to enhance intrinsic motivation in health care students belonging to the Millennial Generation. 相似文献

Owing to the saturation of the efficiency of silicon devices in electronics industry, molecular electronics has gained tremendous
impetus in recent times. Theoretical predictions and experimental realizations of such systems have given birth to a new generation
of miniaturized electronic devices. Organic molecules with delocalized π-electrons show a promising future in this aspect.
The long-standing history and interesting properties of two isomeric organic molecules, naphthalene and azulene, motivate
us to explore their electrical conductance property and possible electronic device applications that exploit the unique characteristics
associated with their structural aspects. Single molecule of azulene shows higher conductivity than naphthalene. The charge
transfer from the seven-membered ring to the five-membered ring in azulene gives the system aromatic stability, making it
dipolar. As a consequence, the conductance becomes asymmetric for forward and reverse bias, opening an efficient application
of azulene as molecular rectifier in electronic device fabrication. 相似文献

The paper analyses the identities of Indian women engineers in the gendered organizational context of US engineering programmes. Participant narratives discuss the ways in which women are subjected to identity struggles in India due to gendered patrifocal norms that impose structural, societal, and familial pressures on women. Subsequently, when these women enter US engineering programmes, they encounter a highly masculine organizational and cultural space. Participants discuss identity dislocations, transformations, and assimilation as they seek to meld into the existing structures and find a career trajectory. I draw upon liminality theory to explore the cultural transitions, identity restructuring, and negotiations of Indian women engineers, navigating the intersections of competing and intersecting cultural norms of gender and engineering in India and the US, work, and family. The findings indicate the layers of gendered ideology that constitute engineering education in India and the US, the societal pressures of marriage and family rooted in patrifocal Indian norms, the barriers to finding an engineering job, the resources within the structures that support women, and the identification of patriarchy as the enactment of agency and as a site for change. 相似文献

Electrorotation is widely used for characterization of biological cells and materials using a rotating electric field. Generally, multiphase AC electric fields and quadrupolar electrode configuration are needed to create a rotating electric field for electrorotation. In this study, we demonstrate a simple method to rotate dielectrophoretically trapped microparticles using a stationary AC electric field. Coplanar interdigitated electrodes are used to create a linearly polarized nonuniform AC electric field. This nonuniform electric field is employed for dielectrophoretic trapping of microparticles as well as for generating electroosmotic flow in the vicinity of the electrodes resulting in rotation of microparticles in a microfluidic device. The rotation of barium titanate microparticles is observed in 2-propanol and methanol solvent at a frequency below 1 kHz. A particle rotation rate as high as 240 revolutions per minute is observed. It is demonstrated that precise manipulation (both rotation rate and equilibrium position) of the particles is possible by controlling the frequency of the applied electric field. At low frequency range, the equilibrium positions of the microparticles are observed between the electrode edge and electrode center. This method of particle manipulation is different from electrorotation as it uses induced AC electroosmosis instead of electric torque as in the case of electrorotation. Moreover, it has been shown that a microparticle can be rotated along its own axis without any translational motion. 相似文献

Historically, indigenous people have been struggling with the issues of material and communicative absences and their voices systematically erased from discursive spaces. Critical-cultural frameworks such as the culture-centered approach (CCA) argue that reflexive engagements with subaltern communities by listening to their narratives are instrumental in interrogating structural absences. By mindfully attending to the emerging contextual narratives, this CCA study examines how indigenous villagers of eastern-India negotiate and exert agency with situated structural absences in their day-to-day existence. This research seeks to explore as well as extend our understanding of structural marginalization and its negotiations in the realm of subaltern agency. 相似文献
