Abstract
Purpose
The purpose of this paper is to investigate the effect of high-k material HfO2 as a buffer layer for the fabrication of metal-ferroelectric-insulator-silicon (MFeIS) structures on Si (100) substrate.
Design/methodology/approach
RF-sputtered Pb[Zr0.35Ti0.65]O3 or (PZT) and plasma-enhanced atomic layer deposited HfO2 films were selected as the ferroelectric and high-k buffer layer, respectively, for the fabrication of metal-ferroelectric-insulator-silicon (MFeIS) structures on Si (100) substrate. Multiple angle ellipsometry and X-ray diffraction analysis was carried out to obtain the crystal orientation, refractive index and absorption coefficient parameters of the deposited/annealed films. In the different range of annealing temperature, the refractive index was observed in the range of 2.9 to 2 and 1.86 to 2.64 for the PZT and HfO2 films, respectively
Findings
Electrical and ferroelectric properties of the dielectric and ferroelectric films and their stacks were obtained by fabricating the metal/ferroelectric/silicon (MFeS), metal/ferroelectric/metal, metal/insulator/silicon and MFeIS capacitor structures. A closed hysteresis loop with remnant polarization of 4.6 µC/cm2 and coercive voltage of 2.1 V was observed in the PZT film annealed at 5000 C. Introduction of HfO2 buffer layer (10 nm) improves the memory window from 5.12 V in MFeS to 6.4 V in MFeIS structure with one order reduction in the leakage current density. The same MFeS device was found having excellent fatigue resistance property for greater than 1010 read/write cycles and data retention time more than 3 h.
Originality/value
The MFeIS structure has been fabricated with constant PZT thickness and varied buffer layer (HfO2) thickness. Electrical characteristics shows the improved leakage current and memory window in the MFeIS structures as compared to the MFeS structures. Optimized MFeIS structure with 10-nm buffer layer shows the excellent ferroelectric properties with endurance greater than E10 read/write cycles and data retention time higher than 3 h. The above properties indicate the MFe(100 nm)I(10 nm)S gate stack as a potential candidate for the FeFET-based nonvolatile memory applications.

Abstract
Purpose
The purpose of this paper is to develop knowledge management constructs comprising of KM processes and KM practices through marketing and sales to derive competitive advantage (CA) in the cement industry.
Design/methodology/approach
A thorough and detailed analysis of the literature was carried out to develop the measures for KM practices, KM processes and their impact on CA. A total of 65 variables affecting competitiveness in the form of questionnaire were developed. The questionnaire was administered through e-mail to 962 territory sales managers (TSM) and equivalent employed in the marketing and sales function of the cement organizations in India. A total of 121 valid and complete responses were received, representing a response rate of 12.6 percent. The factor analysis was carried out on the data collected to establish reliability and validity of the measures.
Findings
A total of seven constructs pertaining to knowledge management practices and processes and competitiveness that comprises of 65 variables have been developed. The statistical results establish that the constructs and the variables considered in the study are reliable and valid.
Research limitations/implications
The sample of respondents for developing constructs consisted of TSM and equivalent employed in the marketing and sales function of cement companies in India. Research scope can be enhanced in the future study by including middle and senior level managers in cement companies to better diagnose and understand perception of KM initiatives across different levels in the cement industry. The work can also be extended to incorporate inbound logistics and procurement that directly contributes to the overall value chain to have a holistic perspective.
Practical implications
The measures developed in this study would be effective management tools for the implementation of knowledge management initiatives in the marketing and sales function to ascertain their level of implementation and impact on the competitiveness.
Originality/value
This study is probably the first of its kind in India to provide KM measures combined for practices and processes to understand the relationship with competitiveness in cement companies pertaining to marketing and sales function. It provides valuable insights as a strategic tool for investing in KM initiatives.

Abstract
Purpose
The purpose of this research is to portray the historical evolution of retailing from 1980 to 2020. The study considers India as the domain as it is one of the fastest growing markets, and the retail growth is anticipated to reach more than one trillion dollars within this decade.
Design/methodology/approach
This paper captures the historical growth trajectory of retailing from the pre-online era to the online era and highlights how the retail environment has become modernized and sophisticated in the process in India.
Findings
The study traces the journey of retail from 1980 to the multi-billion-dollar sector it had become by 2020 in India. Furthermore, the article provides an overview of how the different retail forms and players in the Indian retail sector have been shaping the industry over the last four decades. During this period, there has been a transformational change in the format of Indian retailing. The Indian consumers' shopping mindset moved from physical in the 1980s to online, and now “Phygital” (Physical and Digital) in 2020s has become an omni-channel platform in Indian retail.
Originality/value
This paper aims to present a viewpoint of the evolutions of retailing from the unorganized to the organized form and from the physical to the online form over the last 40 years in the Indian retail sector landscape.

Abstract
This paper presents comparative studies of modern transportation systems in the Bengal Delta and British Borneo. To meet the demands of the new modes of resource extraction, the British colonial rulers introduced a new transportation system in both regions and built roads, railways, and navigational routes connecting major commercial and political centers. There has been little research into the historical connections between modern transportation and environmental changes in colonial South Asia and Malaysia. When modern transportation was introduced, environmental consequences were rarely considered. As a result, significant ecological changes and declines were unintentionally caused. The environmental changes brought about by these transportation systems in these two regions were not the same one from the other. For example, railroad construction harmed the plains and waterways in the Bengal Delta, whereas, in British Borneo, rubber plantations for the global market harmed the rainforests.

Abstract
Purpose
As a developing country, India initiated several labor measures to contain the Covid-19 pandemic. This study analyzes the impact of the Covid-19-induced comprehensive labor measures by Indian states on the Case Fatality Ratios and Recovery Rates. Such an analysis will provide deeper insights into the importance of labor measures during a health emergency. It will also be a reality check to the existing National Health Policy.
Design/methodology/approach
The study examines the four major aspects of labor measures on migration, social security, state-specific needs and health and human rights. The authors use these to formulate a composite labor measure index to comprehend the Covid-19-induced various labor measures. Additionally, the authors apply pooled ordinary least squares and panel random-effects models with the state-wise monthly data to examine the impact of Covid-19-induced labor measures on the severity of the pandemic.
Findings
Covid-19-induced comprehensive labor measures reduce fatalities and increase recovery rates. In particular, the measures on labor migration, state-specific needs and health and human rights adopted by the Indian states successfully reduce the Covid-19 fatalities and improve the recovery rates. However, the measures taken to address social security have been ineffective in reducing the severity of the pandemic. The study results are robust to various other specifications.
Research limitations/implications
The time period covered in this research is very brief and does not account for the qualitative impact of labor measures on the severity of the pandemic. This study specifically addresses the number of Covid-19-induced labor measures and not the resources allocated to their implementations or the number of people who benefited from the measures.
Practical implications
This study emphasizes the need for subnational comprehensive labor measures to reduce the severity of the pandemic in developing countries. The study confirms the need for effective Covid-19-induced social security measures to cope with the pandemic in India. This study also ascertains the beneficial impact of the measures on migration, state-specific needs and health and human rights.
Originality/value
The authors make a composite labor measure index that captures state-level Covid-19-induced labor measures on diverse aspects, namely migration, social security, state-specific need and health and human rights, hitherto unexplored. In addition, the authors analyze the impact of these labor measures on the severity of the pandemic.

Abstract
In this chapter, I explore two media texts, Imtiaz Ali's Highway and Alankrita Shrivastava's Netflix original series Bombay Begums (2021). I contend that recent filmmakers have begun to arguably reframe the narratives of rape victim-survivors and disrupting the cultural of silence described above. They offer progressive and multi-faceted representations of these experiences, such that there is an opportunity for a dialogue within both private and public spheres. What I mean when I say that they are ‘progressive representations’ is that the rape victim-survivors are not merely reduced to helpless women in distress, nor painted as vengeful, aggressive characters. Instead, their characterisation shows that they have agency and autonomy, but at the same time struggle with the repercussions of speaking out against their perpetrators in a society that does not support them wholly.
