Abstract

Purpose

This study aims to analyse the structure of the Indian vaccine supply chain (SC) during the Covid-19 crisis and explore the underlying challenges at each stage in the network. It also brings out the difference in performance of various constituent states.

Design/methodology/approach

This study relied on both primary and secondary data for the analyses. For the primary data, the study gathered experts’ opinions to validate the authors’ inferences. For the secondary data, it relies on government data provided in websites.

Findings

Based on the quartile analysis and cluster analysis of the secondary data, the authors find that the constituent states responded differently during the first and second waves. This was due to the differences in SC characteristics attributed to varied demographics and administrative efficiency.

Research limitations/implications

This paper’s analyses is primarily limited to secondary information and inferences are based on them. The study has important implications for implementing the large-scale vaccination drives by government and constituent states for better coordination and last-mile delivery.

Originality/value

The contribution is unique in studying the performance of constituent states using statistical techniques, with secondary data from authentic sources. It is also unique in combining this observation with validation from experts.

Abstract

Purpose

The purpose of this paper is to determine the feasibility of identifying the creep rupture of reactor cladding tubes using acoustic emission technique (AET).

Design/methodology/approach

The creep rupture tests were carried out by pressuring stainless steel capsules upto 6 MPa at room temperature and then heating continuously in a furnace upto rupture. The acoustic emission (AE) signals generated during the creep rupture tests were recorded using a 150 kHz resonant sensor and analysed using AE Win software.

Findings

When rupture occurs in the pressurized capsule tube representing the cladding tube, AE sensor attached to a waveguide captures the mechanical disturbance from the capsule and these data can be advantageously used to identify the creep rupture event of the cladding tube.

Practical implications

The creep rupture data of fuel clad tube is very important in design and for smooth operation of nuclear reactors without fuel pin failure in reactors.

Originality/value

AE is an advanced non-destructive evaluation technique. This technique has been successfully applied for on-line monitoring of creep rupture of the reactor cladding tube which otherwise could be detected by thermocouple readings only.

Abstract

Purpose

Junior doctors rotating through psychiatry often practise in isolated environments with little prior experience in this field. This can cause anxiety amongst doctors, and may potentially lead to patient safety concerns. The paper aims to discuss these issues.

Design/methodology/approach

A novel peer-led simulation style teaching session was developed to improve junior doctor knowledge and confidence when working with psychiatry rotations out of hours.

Findings

Following successful completion of two iterations of the teaching, junior doctors reported increased confidence, reduced anxiety and a more positive attitude following the session. Facilitators were similarly positive in their feedback, being able to gain formal teaching experience and appraisal.

Originality/value

A novel, inexpensive and easily replicable teaching session is introduced, which can improve junior doctors’ practice and experience when working in psychiatry settings out of hours.

Abstract

Purpose

In this paper, a new front end converter (FEC) topology has been proposed for the switched reluctance (SR) motor drive. This study aims to present the performance analysis of FEC-based SR motor drive using various types of control schemes like conventional proportional integral (PI) controller, fuzzy logic controller (FLC) and fuzzy-tuned proportional integral controller (Fuzzy-PI).

Design/methodology/approach

The proposed FEC-based SR motor drive with various control strategies is derived for the torque ripple minimization and speed control.

Findings

The steady state and the dynamic response of the FEC-based SR motor drive are analyzed using three different controllers under change in speed and loading conditions. The Fuzzy-PI-based control scheme improves the dynamic response of the system when compared with the FLC and the conventional PI controller.

Originality/value

The hardware prototype has been implemented for the FEC-based SR motor drive by using the Xilinx SPARTAN 6 FPGA processor. The experimental verification has been conducted and the results have been measured under steady state and dynamic conditions.

Abstract

As a tribute to Kathy Charmaz, the author discusses the fundamental role that Charmaz's work played in her development as a sociologist and qualitative researcher. The author notes that Charmaz's most prominent contributions are constructivist grounded theory, the notion of methodological self-consciousness, and discussions of the body and emotions as significant to substantive and methodological considerations. The author further describes how the synergy between Charmaz's key concepts and Black feminist perspectives have been relevant to how she leveraged and negotiated her positionality as a Black woman and transnational researcher. Ultimately, the author concludes that Kathy Charmaz's legacy reinforces the importance of equity-minded research and provides a model of how to extend concerns about social justice to activities that also disrupt structural barriers faced by underrepresented researchers.

Abstract

With 43.2 million coronavirus cases and 525,000 deaths in 2022, India ranked second worldwide, after the United States (84.6 million cases and 1 million deaths), according to the latest available June 2022 COVID-19 impact data.

Amid people’s growing mistrust in the government, India’s news media enhanced the nation’s distinguished designation as the world’s largest and most populous democracy. India’s news media inform, educate, empower, and entertain a surging population of 1.4 billion people, which is roughly one-sixth of the world’s people.

Drawing upon the media agendamelding theoretical framework, we conducted a case study research into interplay between two prominent democratic institutions, the media and the government, to analyze the role of the COVID-19 pandemic in redefining India’s networked society.

India’s COVID-19 pandemic aggravated internecine tensions between media and government relating to four key freedom issues: (1) world’s largest COVID-19 lockdown affecting 1.3 billion Indians from March 25, 2020 to August 2020 with extensions and five-phased re-openings, to restrict the spread of COVID-19; (2) Internet shutdowns; (3) media censorship during the 1975–1977 “Emergency”; and (4) unabated murders of journalists in India.

Although the COVID-19 pandemic caused deleterious problems debilitating the tensions between the media and the government, India’s journalists thrived by speaking truth to power. This study delineates key aspects of India’s media agendamelding that explicates how the people of India form their media agendas. India’s news audiences meld media messages from newspapers, television, and social media to form a picture of the issues, insights, and ideas that define their lives and times in the 21st century digital age.

Abstract

Distance education techniques perceived holistically can and should be applied to literacy campaigns. In fact when we pose the question: ‘who is the distant learner’ the illiterates, semi‐literates and neo‐literates form tangible target groups. The first generation of distance education which organised and sustained the print media has been used very effectively for literacy measures in the form of primers, practicing writing/ numeracy skills etc. In fact the learning material prepared for literacy purposes is an indicator of Distance Education Methodology, as the print material which is the basic medium of instruction in Distance Education, is used for learners to be literates and neotiterates.
