First person – Poonam Sehgal
No full textABSTRACT
First Person is a series of interviews with the first authors of a selection of papers published in Journal of Cell Science, helping early-career researchers promote themselves alongside their papers. Poonam Sehgal is the first author on ‘Epidermal growth factor receptor and integrins control force-dependent vinculin recruitment to E-cadherin junctions’, published in Journal of Cell Science. The work in this article was carried out while Poonam was a postdoc in the lab of Dr Deborah Leckband at University of Illinois, Urbana-Champaign, USA, investigating the mechanism of E-cadherin-mediated force-transduction signaling in epithelial cells.</jats:p
"There are millions of young Indians who feel frustrated with their lives.... I really want the Indian government to take these frustrations seriously." - Snigdha Poonam
No full textLSE South Asia Centre recently invited Snigdha Poonam, journalist at Hindustan Times and author of Dreamers: How Young Indians are Changing the World, for a panel discussion entitled 'Who are the Middle Class in South Asia?' as part of the South Asia Summit 2018. In conversation with Anirbaan Banerjee, she talks about aggressive Indian nationalism, the political and economic frustrations of the middle-class young Indian, women's aspirations and a growing social-political crisis in India
Application of Emerging Technology in an Emerging Economy : case of GovTech through blockchain-based seeds traceability in Jharkhand
No full textA strong agriculture sector plays an important role in ensuring the food security of a country. In addition to the ecological and social importance of seeds, the seeds’ quality holds the utmost priority in the agricultural supply chain, thus governments are employing tactics focused on seed quality, and traceability. Governments have been deploying emerging technological tools to monitor the various phases of the agricultural supply chain. This paper analyzes the role of GovTech in agricultural seed traceability. I examine the same by understanding the deployment of blockchain-based techniques by the government of the Indian state of Jharkhand. Thus, this paper demonstrates the responsible action undertaken by the government to ensure transparency, efficiency, and immutability in the agricultural supply chain data which leads to effective seed traceability and eventually quality. The paper presents a potential guide for policymakers and government institutions in reconfiguring the agricultural sector
Land use as possible strategy for managing water table depth in flat basins with shallow groundwater
No full textIn flat plains groundwater affects agricultural production outcomes and risks. Agricultural land use decisions, however, may strongly impact groundwater levels available for production. This paper explores the scope for managing groundwater levels through land use decisions in a sub-basin of the Salado River in the Argentine Pampas, a very flat area that plays a key role in world agricultural production. A spatially distributed hydrological model implemented with MIKE SHE software was used to establish the impacts of different land uses on groundwater dynamics, and to assess the interdependencies among spatially close decision-makers sharing a water table (WT). Additionally, groundwater level changes in response to climate variability were quantified. We found land use has strong effects on WT levels both for oneself (e.g. pastures can lead to significant decreases (up to 4.5 m) in WT levels) and others, in the form of strong interdependencies that exist between farmers sharing a WT where land use decisions of one farmer effect groundwater level of neighbouring farms and vice versa. However, the effectiveness to control groundwater levels through land use decisions is subject to the rather unpredictable effects of rainfall variability. The results presented in this paper provide key insights in relation to physical and social aspects that should be considered for managing groundwater levels through land use decisions, in order to avoid negative and/or maximize positive effects on agricultural production.Fil: García, Pablo Enrique.

Design, Realization and Applications of Dynamically Controllable Bragg Gratings
No full textThis dissertation emphasizes on the realization, investigation and manipulation of Bragg gratings with external electrical control especially for spectral filtering applications. Volume photorefractive Bragg gratings realized in bulk lithium niobate crystals are manipulated with external electric field in order to demonstrate fast electrically switchable holographic lenses and mirrors. Furthermore, photorefractive Bragg gratings are inscribed in lithium niobate waveguides and a fast electrically tunable integrated optical spectral filter is demonstrated. In addition, a detailed investigation of higher harmonic components of nonlinear photorefractive waveguide gratings in reflection geometry has been reported. The most important and interesting part of the entire work is the introduced concept of phase-shift keying of corrugated waveguide Bragg gratings which was used to dynamically reconfigure the Filter transfer function. This novel concept comprises, for the first time to the best of my knowledge, the use of external electric field to dynamically inscribe phase-shifts to more than two sections of the already fabricated integrated corrugated Bragg grating. Employing this technique, a fast (< one microsecond) reconfiguration or synthesis of the transfer function into several desirable profiles is demonstrated. Some of the realized reconfigurations e.g. continuous tuning of a single selected channel, reconfiguration from pass-band to stop-band, reconfiguration from one to two, three and five pass-bands, reconfiguration to a flat-top profile, dynamic correction of the transfer function profile, dynamic control of the bandwidth and the shape of the transfer function are presented and discussed. One of the most promising results was the estimation of switching time. The demonstrated switching with time less than 1 microsecond (few GHz). With such fast switching, the proposed integrated optical filters with reconfigurable transfer functions are very promising not only for the existing DWDM networks but also for the next generation high-speed reconfigurable telecommunication networks like OCDMA (optical code division multiple access)

Redesigning Human Resource Management System through Cloud Computing: A Strategic Approach
No full textCloud computing is enabling human resource (HR) management functions to strategically integrate into business operations. Its acting as a game changer for HR amid intense competition to survive and grow. Digital disruption, transformation, agility has set the new benchmarks for organizations to automate and redesign their functions. Cloud Computing offers HR a completely new dimension with cloud centric benefits like reduction in communication gap, increased organizational excellence, effective talent strategies, data driven decision making, and supporting revenue in organizations. Cloud Computing has the right capability to redesign major HR functions with agility to match the changing requirements of business, automating transactional activities, smarter decision making and meeting the business expectations. Use of HR cloud in organization can result into structural benefits beyond technological advancements. Cloud HR gives organizations flexibility of location, prompt information processing, effective use of data analytics and strategic decision making. This paper discusses ways through which cloud computing could be integrated into HR functions. An analysis on applications of cloud computing in human resource areas with their outcomes is also presented in this paper. A brief note on future prospects of cloud computing in HRM is also discussed
