Responding to Professional Knowledge Disruptions of Unmitigable Uncertainty: The Role of Emotions, Practices, and Moral Duty among COVID-19 Physicians
No full textDrawing on an in-depth study of physicians facing the Covid-19 pandemic in Italy in 2020, we advance theory on how professionals in their workplace respond to knowledge disruptions associated with complex societal challenges that undermine the adequacy of their knowledge base to solve professional problems. We show that, in the context of the uncertainty generated by the knowledge disruption and unable to mitigate it through typical knowledge-based strategies, professionals experience a trail of negative epistemic emotions linked to the immitigability of this uncertainty. Despite these negative epistemic emotions and motivated by a heightened sense of moral duty, professionals engage in service-oriented practices of collegial and humanistic work that depart from the knowledge-centric practices of their usual work. We detail how the repeated development of positive moral emotions when performing of such practices leads professionals to ultimately consolidate and embed service-oriented practices in their professional work. Our study contributes to the literature on professions and organizations by theorizing the distinctive category of knowledge disruptions of unmitigable uncertainty and by uncovering the micro-level dynamics and mechanisms that sustain professionals’ responses

Investigating the revised international marketing strategies during COVID-19 based on resources and capabilities of the firms: A mixed method approach
No full textThis paper aims to identify the revised international marketing strategies in communication during the COVID-19 pandemic by utilizing the firm's resources and capabilities. We conducted in-depth interviews and a questionnaire survey with key stakeholders of retail organizations which changed their digital marketing strategies during COVID-19. The data is collected from 587 respondents from different parts of the world through resource orchestration theory. The qualitative findings support a high degree of association among the firm’s resources and capabilities, leveraging processes based on the revised international marketing strategies during the COVID-19 pandemic. We have developed a conceptual model based on these findings with six variables: leveraging process of the firm’s capabilities information technology-related resources; information technology-related capabilities, dynamic capabilities, environmental uncertainty, and leveraging process of the firm’s resources. However, environmental uncertainty and leveraging of the firm’s resources were not influential in forming digital marketing strategies during COVID-19. This study proposes a new process for international marketing managers in business organizations to restructure the resources within their organizations by creating new capabilities and leveraging them

No full textMapping of arsenic contamination severity in Bahraich district of Ghagra basin, Uttar Pradesh, India
No full textArsenic testing work has been carried out in Uttar Pradesh by UP Jal Nigam during the period 2005–2008. During this period, arsenic testing was performed using field test kits for 150,000 sources employing screening and blanket testing approach. The current paper describes the work of geographical information system (GIS) mapping in Bahraich district. The district has two physiographic units – Uprahar and Tarhar to depict highland and lowland Quarternary alluvial plains. Out of 30,216 India Mark II hand pumps in the district, arsenic testing was performed, by UP Jal Nigam for 13,812 hand pumps, out of which 7190 (52.06%) tested sources show arsenic value > 0 μg/L. Further segregation of data shows that 56.66% of affected sources fall in 10–40 μg/L category and 10.86% sources fall in >50 μg/L category. Village level mapping of affected sources at GIS platform shows arsenic concentration is more in Huzoorpur and Tajwapur blocks which lie in lowland physiographic unit
The regional economic impacts of biofuels: A review of multisectoral modelling techniques and evaluation of applications
No full textThe regional economic impact of biofuel production depends upon a number of interrelated factors: the specific biofuels feedstock and production technology employed; the sector’s embeddedness to the rest of the economy, through its demand for local resources; the extent to which new activity is created. These issues can be analysed using multisectoral economic models. Some studies have used (fixed price) Input-Output (IO) and Social Accounting Matrix (SAM) modelling frameworks, whilst a nascent Computable General Equilibrium (CGE) literature has also begun to examine the regional (and national) impact of biofuel development. This paper reviews, compares and evaluates these approaches for modelling the regional economic impacts of biofuels.biofuels; economic modelling; input-output; social accounting matrix; computable general equilibrium.

UIDB/04152/2020 Centro de Investigação em Gestão de Informação (MagIC).Climate change poses a significant threat to coastal regions worldwide. This study presents and applies a modified CVI to assess coastal vulnerability at the village level, focusing on Canacona, a taluka in South Goa, India. It adapts the existing CVI methodology by incorporating additional variables to represent the various dimensions of vulnerability better, resulting in 21 variables split into a Physical Vulnerability Index (PVI) and a Social Vulnerability Index (SoVI). The results show spatial variability in coastal vulnerability across the studied villages, with Agonda and Nagercem-Chaudi found to be highly vulnerable and Loliem to be the least vulnerable. A hydrological modeling approach is also used to compare the CVI of every village with their susceptibility to inundation due to rising sea levels. The result demonstrates the influence of local factors on vulnerability, challenging previous taluka-level assessments given the typical scale upon which adaptation typically takes place.publishersversionpublishe
Quantification of benefits of the campus grid operations as a microgrid
No full textThe US grid's weak ability to withstand severe weather incidents, particularly with the growing number of events due to climate change, the slow pace of expansion of transmission grids and the increased push to integrate deeper penetrations of renewable resources in recent years, has raised many questions about the reliability and resilience of the electricity supply as well as about the design and operational paradigm of the distribution grid. The increased implementation of microgrids in distribution networks (DNs) indicates that microgrids provide promising alternative approaches to address many of these issues. The growing interest in microgrid implementations provides evidence that many projects are, in effect, able to realize such benefits. However, the lack of a general methodology that can comprehensively quantify the benefits of applying the microgrid concept to any power system limits the much broader implementation of microgrids as the investments made in the microgrid area are not justified. In light of this situation, we developed a quantification methodology and carried out the quantification and comparative analysis of the benefits of the operation of the University of Illinois at Champaign-Urbana (UIUC) campus utility system (CUS) as a microgrid versus its current operations. The UIUC campus is a microcosm of a city with diverse facilities including the academic buildings and laboratories, student housing facilities, theatres, health center, sports stadiums, libraries, veterinary hospital and an airport. The UIUC campus is critically dependent on the CUS for its chilled water, steam and electricity demands year round. The UIUC CUS has all the required characteristics of a microgrid including distributed energy resources (DERs), critical and non–critical loads and a defined electrical grid boundary. Thus, we may view the CUS as a microgrid. Consequently, consideration of the UIUC CUS via microgrid optics allows us to carry out a comparative quantification of the benefits of the UIUC CUS operated as a microgrid versus under the current operational paradigm.
For the quantification methodology, we use a stochastic simulation approach that provides the capability to quantify the impacts of CUS operations in terms of economic, reliability and emissions metrics of the CUS operations under a specified operational paradigm. The approach is based on the explicit representation of the various sources of uncertainty together with the time-varying nature in the demand–side and supply–side resources in the CUS. The simulation approach models the uncertainty in the demands, available capacity of conventional generation resources and the time–varying, intermittent renewable resources in terms of discrete–time random processes (r.p.s). Such a representation explicitly takes into account the time correlations in each input variable. A key exponent of the simulation approach is the formulation of the so–called energy scheduling optimization problem (ESOP). The ESOP solution is an essential building block in our approach and is used to determine the CUS resource scheduling decisions with the explicit consideration of the uncertainty effects. Under the current operational paradigm, the schedule of the energy resources is based on heuristic techniques and does not involve the deployment of formal optimization techniques. The ESOP solution replaces the current heuristics–based approach to determine the optimal schedule and loading levels of the CUS energy resources so as to minimize the CUS operational costs. We use this optimal scheduling as a proxy for the current operational paradigm. In this way we can carry out on a consistent basis a comparative analysis of the UIUC CUS operational performance as a microgrid – the so–called microgrid operational paradigm – and those under the optimal operations of the current paradigm. A modified ESOP and its solution is also adopted in the simulation methodology for the quantification of the CUS operational performance under the microgrid operational paradigm. A salient feature of the ESOP mathematical formulation is its ability to capture the inter–dependencies in the electricity and steam services that the UIUC CUS provides under each operational paradigm. The simulation approach makes use of the Monte Carlo simulation (MCS) techniques to represent the impacts of sources of uncertainty on the CUS operations under each operational paradigm. As such, we systematically sample the r.p.s to generate the realizations, or sample paths, that we use to emulate the scheduling of the CUS for a given operational paradigm via the ESOP. The ESOP solution maps the sample paths of the loads and supply resources into the sample paths of the r.p.s we use to measure the performance of CUS operations. The evaluation of the metrics of interest is based on these resulting s.p.s.
We demonstrate the capabilities of the simulation approach by carrying out various case studies on the UIUC CUS. We discuss a set of representative studies to gain important insights about the current UIUC CUS operations and under the application of the microgrid concept to the UIUC CUS. The studies provide clear understanding of the interactions between the electric and steam utility in the UIUC CUS and the limitations on electric system operations imposed by the requirement to meet the steam loads. A key observation made from these case studies is that the extent of the benefits of the microgrid concept application to a power system attained would depend on the characteristics of the system as well as the location of the system in the geographical footprint of the distribution system.
There is a broad range of applications of this methodology, including resource planning studies, reliability, economic and environmental assessments and operational studies. A particularly attractive feature is its ability to provide answers to various “what if” questions of any nature. The methodology described in this thesis is general in a sense that it can easily be adapted to demonstrate the extent to which the benefits of the microgrid concept application can be realized in any particular power system when it is operated as a microgrid versus when it is operated under its current paradigm.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2019-05-01The student, Siddhartha Nigam, accepted the attached license on 2017-04-25 at 13:56.The student, Siddhartha Nigam, submitted this Thesis for approval on 2017-04-25 at 14:50.This Thesis was approved for publication on 2017-04-26 at 13:32.DSpace SAF Submission Ingestion Package generated from Vireo submission #11048 on 2017-08-10 at 15:06:59Made available in DSpace on 2017-08-10T20:33:24Z (GMT).
