- Tracing Feminist Discourse in the Intellectual Output of Women Trade Unionists in Late Colonial Bengal November 28, 2024
Dr Manaswini Sen, Assistant Professor at the Department of History, has published an insightful paper tracing the ideological and intellectual output of women trade unionists in late colonial Bengal. Her research paper titled “(Re)Inventing Feminism within the Discourse of Class Struggle: Women and Intellectual History in the Trade Union Movement of Late Colonial Bengal (1920–1947)”, published in the prestigious Journal of the History of Women Philosophers and Scientists, offers a novel perspective on understanding the class struggle, anticolonial discourse in the patriarchal society of colonial Bengal.
Abstract
This paper envisages (re)constructing the intellectual praxis of women trade unionists in late colonial Bengal. By arguing how political practice habitually translates to political thought, the paper devises a methodology to address the gendered discourse of intellectual history in the Global South. It focuses on intellectual output, primarily journal articles of women trade unionists like Santoshi Kumari Gupta, Maitreyee Bose, and Kanak Mukherjee, to trace a genealogy of how class struggle was perceived by women labour activists across the ideological spectrum of nationalism, socialism, and communism between 1920 to 1947 in Bengal. The piece is an effort to transcend the manifold marginalisations that plague the establishment of feminine political praxis within the regulating structures of colonialism and capitalism. In the process, it bids to unfold an alternative narrative of the anti-colonial, anti-capitalist, and anti-patriarchal narrative of the decolonisation of South Asian intellectual thought.
Research, Collaboration and Future Research Plans
The research strives to bring to the forefront the intellectual contributions of three female trade unionists in the late colonial period to trace the evolution of discourses on anticolonial class struggle from a gendered perspective. With the global turn in intellectual history, there is an augmented effort at amplifying the ‘small voices of history’. The inherent socio-cultural predicaments in our society make it inordinately challenging to trace conventional sources for mapping the intellectual endeavours of women. This paper aims to rectify this gap by reconstructing women labour activists’ intellectual practises and literary output in the early 20th century. In the process, the research tries to bring forth narratives of anticolonialism, which drowns in the overwhelming presence of nationalism in the discourses of decolonisation of South Asia. This paper was the result of academic exchanges with professors of Benaras Hindu University, Dr B.R. Ambedkar University, Delhi, and the University of Paderborn, Germany.
Dr Sen primarily researches marginal anticolonial epistemological traditions of South and South East Asia. Her thesis on the evolution and dissemination of socialism in late colonial Bengal, which focuses on an intellectual history of trade unionism, forms the basis of her first monograph. However, she is now focusing on the transnational and transcontinental intellectual networks of a wide spectrum of leftist labour activists and proto-nationalists and the ways these fringe intellectual traditions interacted with each other and nationalism. Based on a rich archive across India and Europe and a plethora of alternative sources, she tends to devise new methodological interventions in the field of Global Intellectual History, making labour history more accessible and relevant in scholarly circles.

Dr Partha Bhattacharjee, Assistant Professor from the Department of Literature and Languages, along with his scholar Mr Rounak Gupta has published their paper titled “Fractured Identities and Wounded Memories in Indian Comics on Partition: A Decolonial Reading of Frame and Panel” in the esteemed Q1 journal Journal of Graphic Novels and Comics. This paper explains comics as a medium whose panels, frames, and stylistic aspects can be interpreted in the Indian context. This interpretation has been read as a decolonial intervention into the medium’s history and the established aesthetic theories.
Abstract
Within the liaison of decoloniality studies and comics studies, this paper investigates how the decolonial visual style in the comics anthology This Side That Side (2013) has been used to locate the traumatised past and violation of human rights due to the “b/ordering” practices of partition of India (Rifkind 2017; Bhattacharjee and Tripathi 2022). “The Taboo” by Malini Gupta and Dyuti Mittal, “An Afterlife” by Sanjoy Chakraborty, and “Making Faces” by Orijit Sen cultivate the stories of the inhumane condition of the migrants and victims during and after the Indo-Pakistan and Indo-Bangladesh-Pakistan partition. These narratives exemplify decolonised counter comics narratives on collective and personal memories (Chute 2016; Mickwitz 2016; Ahmed and Crucifix 2018) inflicted upon and against the dominant partition discourse. They help churn out the human stories of the interminable psychological violence of partition and post-partitioned reality.
The paradigm established in this research can later be used to interpret different formations within comics, especially pertaining to decolonial aesthetics, dialogue, and attitude.

The complexities of identity in literature are a significant area of scholarly inquiry, especially in colonial and postcolonial studies. A key addition to this discourse is Assistant Professor, Dr Stella Chitralekha Biswas’ book chapter on “The Child is the Father: The Dynamics of Identity-Formation in Juvenile Literature.” in the anthology, (Re)Framing Identity: Responses from History, Culture and Literature by Atlantic Publishers & Distributors.
A Brief Introduction to the Book:
This anthology (Re)Framing Identity: Responses from History, Culture and Literature is a significant and timely effort to understand the issues of identity because in the postmodern age, it is one of the highly debated and discussed issues in the field of History, Culture and Literature. In the postmodern age, the question of identity with reference to literature becomes important because the monolithic idea of identity is challenged in both imaginative and critical works. The significance of this anthology also lies in the fact that it scrutinizes the process of identity formation in the Indian subcontinent and problematizes the notions of its unity and continuity across time and space philosophers. This anthology continues the tradition of the critique of identity formation right from Stuart Hall, who, in his article in Questions of Cultural Identity (1996) says, “The deconstruction has been conducted within a variety of disciplinary areas, all of them, in one way or another critical of the notion of an integral, originary and unified identity”. Therefore the purported aim of this anthology is to analyse the conflicts and amalgamation among numerous races, ethnic groups, religions, linguistic acommunities and various other stakeholders and to understand how these conflicts and amalgamations resulted in the formation of diversified identities in the light of Stuart Hall’s ideas, “identities are never unified and, in late modern times, increasingly fragmented and fractured; never singular but multiply constructed across different, often intersecting and antagonistic, discourses, practices and positions. They are subject to a radical historicization, and are constantly in the process of change and transformation”
Significance of the Book Chapter:
The understanding of identity formation has evolved from the philosophical understanding to its discursive formation and further to the neurological understanding of how identity is shaped. The fundamental idea followed in the anthology can be summed in by Stuart Hall, “actually identities are about questions of using the resources of history, language and culture in the process of becoming rather than being: not ‘who we are’ or ‘where we came from’, so much as what we might become, how we have been represented and how that bears on how we might represent ourselves. Identities are therefore constituted within, not outside representation. They relate to the invention of tradition as much as to tradition itself, which they oblige us to read not as an endless reiteration but as ‘the changing same’ not the so-called return to roots but a coming-to-terms-with our ‘routes’. They arise from the narrativization of the self, but the necessarily fictional nature of this process in no way undermines its discursive, material or political effectivity, even if the belongingness, the ‘suturing into the story’ through which identities arise is, partly, in the imaginary (as well as the symbolic) and therefore, always, partly constructed in fantasy, or at least within a fantasmatic field”. This particular analysis of identity formation in the Indian subcontinent under numerous pressures exerted through various mediums like literature, folk theatre and literature and philosophical texts not only in India but outside as well among the Indian diaspora located especially in Euro-American parts of the world, making this anthology a crucial book not only in the country but also at an international level.
Target Audience:
It is inspiriting to read such exhaustive literary anthology by eminent academicians and scholars and broadens one’s horizon of critical thinking as one goes through the collection. The book will definitely open up new trajectories of research in the field of postcolonial studies, bhasha literature and identity theory. It will also motivate students and researchers to explore the formation and representation of identities in the subcontinent in terms of culture, race, ethnicity, language, religion, caste, gender and politics.

This research paper titled, “Continuously-tunable, compact, freespace notch-filter design using an all-dielectric metagrating capped with a low-loss phase change material” by Dr Devdutt Tripathi, Assistant Professor, Department Electronics and Communication Engineering explores the use of active metasurfaces combined with phase change materials (PCMs) to enhance optical technologies thereby enhancing optical technologies across various sectors including telecommunications and imaging sectors.
Abstract:
Active metasurfaces utilising phase change materials (PCMs) are currently under investigation for applications in free-space optical communication, optical signal processing, neuromorphic photonics, quantum photonics, and compact LiDAR. Attention has now turned towards novel PCM like Sb2S3 which exhibit lower optical absorption and reasonable values of refractive-index contrast in comparison to traditional data-storage PCM. We propose and numerically study the class of all-dielectric metagratings capped with low-loss PCM and predict the possibility of continuously tunable resonances whose quality factors degrade gracefully during the amorphous-to-crystalline phase transition of the PCM. Specifically, we consider the CMOS-compatible silicon-nitride on silica substrate material platform for simple and asymmetric metagratings (in particular, the symmetric-broken dimerization) and Sb2S3 capping. Our numerical study predicts that notch-filters operating around the 1550 nm NIR wavelength window can be achieved with tuning range of over 76 nm with Q-factors ranging from 784 (amorphous-phase) to 510 (crystalline-phase) (a degradation in Q of about 35%) and insertion loss of about 0.9 dB. These performance figures are a significant improvement over previously published designs utilizing data-storage PCMs and other traditional notch-filter mechanisms. We examine the influence of grating dimerization and geometrical parameters on performance metrics of the notch-filter and predict the possibility to trade-off rejection-band and in-band spectral transmission properties. Lastly, we perform a study of an all-optical phase change mechanism. Our study is promising for the miniaturization of tunable notch-filter based optical systems.
Explanation in Layperson’s Terms:
This research explores the use of advanced materials called metasurfaces (engineered materials especially in a 2D thin film structure), combined with phase change materials (PCMs- Semiconducting alloys of the Chalcogen family), for improving already existing and emergent technologies such as Optical communication, LiDAR (an acronym for Light Detection and Ranging), and Quantum photonics. Metasurfaces are thin layers with typical thickness ranging from a few hundred nanometers to several micrometers that can manipulate light in unique ways. In this study, the focus is on a specific PCM, Antimony Trisulphide (Sb2S3), which exhibits lower light absorption and better control over how it interacts with the incident light compared to traditional PCMs such as GST225 (Germanium Antimony Telluride) used in data storage. We propose a new design of metasurfaces, called metagratings, that can be “tuned” by changing the state of the PCM between amorphous and crystalline forms. The study predicts that these metasurfaces can be used to create notch filters, which block specific wavelengths of light, particularly around the 1550 nm range commonly used in fiber optics. When the PCM switches states, the filter can shift by 76 nm, with only a minor decrease in performance, about 35%. The study also looks at how small changes in the shape and structure of the metagratings can fine-tune their performance, allowing for a balance between filtering strength and light transmission. Overall, this research points to a promising way of miniaturizing and improving tunable optical filters for a range of high-tech applications.
Practical Implications:
This research has several practical implications:
1. Optical Communication: It can improve free-space optical
communication by offering tunable filters to enhance signal clarity and reduce interference.
2. Miniaturized LiDAR: Smaller, more efficient LiDAR systems for autonomous vehicles and 3D mapping can be developed.
3. Optical Signal Processing: Faster, more efficient photonic circuits could be created for data processing and telecommunications.
4. Neuromorphic and Quantum Photonics: The tunable metasurfaces can support advanced computing and quantum technologies by precisely controlling light.
5. Energy Efficiency: Sb₂S₃ uses less power than traditional materials, making devices more energy-efficient.
6. Sensing and Imaging: It can improve sensors and imaging systems by allowing more precise wavelength control.
7. CMOS Compatibility: The research can be integrated into existing semiconductor technologies, facilitating mass production.

The Sundarbans represent the largest mangrove system on Earth, covering >10,000 km2. These mangroves can export a vast amount of aquatic carbon that can be potentially sequestered for millennia. Dr Kousik Das, Assistant Professor at the Department of Environmental Science and Engineering, collaborates with Southern Cross University, Australia and IIT Kharagpur to conduct breakthrough research to analyse and estimate the carbon flux between the Sunderbans and the Bay of Bengal. He has published a research paper titled “Groundwater discharge and bank overtopping drive large carbon exports from Indian Sundarban mangroves” in the Q1 journal Science of The Total Environment, having an impact factor of 8.2.
Abstract
We estimate porewater-driven carbon exchange between the Sundarbans and the Bay of Bengal using high-resolution time series and a radon groundwater mass balance approach spanning a neap-spring tidal cycle. Submarine groundwater discharge (SGD) increased from neap to spring tides by 352 % up to a maximum of 65.6 cm d−1 largely driven by creek bank overtopping after the mid-tide. Exports of dissolved organic and inorganic carbon and alkalinity doubled between neap and spring, likely due to the ‘first flush’ of older porewater in the mangrove flats. Groundwater discharge was a significant driver of the net carbon export, contributing up to 86.7 % of DIC and 74.0 % of alkalinity during the spring tide while contributing a lower proportion of DOC (4 %–23 %). If these results are representative of the Sundarbans more broadly, carbon fluxes from the Sundarbans would be more than an order of magnitude higher than some of the world’s largest rivers on an areal basis, highlighting the importance of Sundarbans mangroves to global oceanic carbon budgets.
Practical Implementation/Social Implications of the Research
This study shows the global importance of the Sundarbans mangrove system, with significant dissolved inorganic carbon and total alkalinity fluxes to the Bay of Bengal. It also shows that mangrove SGD is an important driver of dissolved inorganic carbon, dissolved inorganic carbon (DIC) and total alkalinity (TAlk) exports and that bank overtopping during mid and spring tides drives a ‘first flush’ of carbon from groundwater. When carbon fluxes from the study site were upscaled to the entire inundated area of the Sundarbans, DIC and TAlk exports were smaller than some of the world’s largest rivers, however when adjusted to the catchment size (assuming the Sundarbans mangrove catchment area is the extent of the mangroves; 10,200 km2), the areal carbon fluxes from the mangroves are more than an order of magnitude higher than these river systems
Dr Das aims to continue his research and further explore the large flux of carbon export due to tropical cyclones from the Indian Sundarbans to the Bay of Bengal.

With the advent of cutting-edge technology, Dr Abhijit Dasgupta, Assistant Professor at the Department of Computer Science and Engineering, has conducted breakthrough research in understanding biochemical systems with limited data in hand. His research has been published as a paper titled “Efficient Parameter Estimation in Biochemical Pathways: Overcoming Data Limitations with Constrained Regularization and Fuzzy Inference” in the Elsevier journal Expert Systems With Applications, having an impact factor of 7.5.
Abstract
This study introduces a new method to estimate parameters in biochemical pathways without relying on experimental data. The method called the Constrained Regularized Fuzzy Inferred Extended Kalman Filter (CRFIEKF) uses fuzzy logic to estimate parameters based on known but imprecise relationships between molecules. To handle complex and unstable data, the method incorporates Tikhonov regularisation, improving accuracy and stability. CRFIEKF was tested on several pathways, including glycolysis and JAK/STAT signalling, and reliable results were obtained. This approach offers a useful tool for estimating parameters in complex biochemical systems, especially when experimental data is limited.
Explanation of the Research in Layperson’s Terms
This research is about finding a new way to predict how living cells work, especially when scientists don’t have enough data from experiments. Normally, to understand how cells function, scientists need to collect a lot of information over time, which can be costly, difficult, or even impossible.
To solve this, the researchers developed a new method that doesn’t need as much experimental data. Instead of relying on exact measurements, their method uses fuzzy logic, which is like making smart guesses based on patterns and relationships we know, even if we don’t have perfect information. They also used a technique to keep these guesses steady and reliable, even when the data is messy or incomplete.
They tested this method on different biological processes, such as how cells turn food into energy (a process called glycolysis) and how cells send signals using proteins (like in the JAK/STAT pathway). The method worked well and gave accurate results.
In simple terms, this research helps scientists predict how cells behave without needing a lot of expensive and hard-to-get data, making it easier to study the complex systems inside living organisms.
Practical Implementation/Social Implications of the Research
The practical implementation of this research lies in its ability to accurately predict how biological systems, such as cells, function without relying heavily on time-consuming and costly experimental data. This method can be applied in various fields, including drug development, personalised medicine, and agriculture, where understanding complex biological processes is crucial. For instance, pharmaceutical companies could use this technique to model how a drug will interact with different biological pathways, speeding up the drug discovery process. Similarly, it could help tailor medical treatments to individual patients by predicting how their unique biological makeup will respond to specific therapies.
The broader social impact of this research is significant. By reducing the need for extensive experimental data, this method can lower the cost and time required for scientific discoveries in healthcare and biotechnology. This could lead to faster development of new medicines, more affordable healthcare solutions, and personalised treatments that improve patient outcomes. In agriculture, this method can help optimise crop growth and resilience, contributing to food security. Overall, this research provides a pathway for more efficient and cost-effective advancements in biology, healthcare, and environmental sciences, ultimately benefiting society by improving health and sustainability.

Future Research Plans
Building on the foundation laid by this research, the next steps will involve expanding its applications to more complex biological systems and personalised medicine. The following outlines a future roadmap:
1. From Time-Course Data to Pathway Enrichment and Single-Cell Modeling:
The current method, which estimates parameters without relying on time-course data, can be adapted to use time-course data when available. Time-course data captures how biological processes change over time, offering valuable insights. By integrating this data, we can refine the parameter estimation and achieve a more precise pathway enrichment analysis. This approach can be particularly beneficial in single-cell studies, where understanding the variability in cellular responses within complex diseases like cancer, diabetes, or neurodegenerative disorders is crucial. Modelling these pathways at the single-cell level will enable us to capture heterogeneity within tissues and improve disease understanding.
2. Simulating Pathways to Identify Drug Targets:
Once the pathways are enriched and modelled, we can simulate these biological networks to predict how different interventions—such as drugs—might influence the system. This simulation can help identify potential drug targets, particularly those that are critical in disease progression. For instance, by manipulating the modelled pathways, we can observe how specific proteins or molecules influence the disease state, providing insights into where a drug could be most effective.
3. Predicting Drug Side Effects:
After identifying potential drug targets, the next step is to predict the side effects of these interventions. The same model can simulate unintended consequences by analysing how modifying a target impacts other connected pathways. This simulation can provide early warnings about potential side effects, reducing the risk during later stages of drug development. Understanding these off-target effects at an early stage will be crucial for designing safer drugs.
4. Predicting Drug Molecules Using Generative Adversarial Networks (GANs):
Incorporating machine learning, particularly Generative Adversarial Networks (GANs), can take this research to the next level. GANs can be trained to generate new drug molecules by learning from existing drug databases. By feeding the pathway model’s identified targets into the GAN, we can generate candidate drug molecules that are predicted to interact with these targets effectively. This approach can significantly speed up the drug discovery process by automating the design of new drug candidates tailored to specific biological pathways.
5. Integration with Omics Data for Personalized Medicine:
The future of personalised medicine relies on integrating various layers of biological data—such as genomics, transcriptomics, proteomics, and metabolomics—into a cohesive model. By integrating pathway data with these other “omics” layers, this research will facilitate a more comprehensive understanding of individual patient biology. This integration allows for tailored treatment strategies, making personalised medicine more achievable. For instance, based on an individual’s genetic makeup and biological pathways, we can predict how they will respond to specific drugs and design personalised therapies with minimal side effects.
6. Pathway-Based Drug Design and Validation:
Once potential drug molecules are identified using GANs, they can be simulated within the enriched pathways to test their efficacy in silico. These simulations will allow researchers to understand how the drug interacts with the target pathway and its downstream effects. If the simulation shows promising results, the drug candidates can be prioritised for lab testing and clinical trials. This systematic approach, from modelling to simulation, could drastically reduce the time and cost associated with traditional drug discovery processes.
Summary
This plan transforms the current research from a powerful parameter estimation technique into a comprehensive framework for personalized medicine and drug discovery. By expanding to time-course data, single-cell modeling, pathway simulation, and integrating cutting-edge AI techniques like GANs, we can predict drug molecules tailored to individual biological systems. This personalized approach not only streamlines drug discovery but also enhances the safety and effectiveness of treatments, paving the way for more efficient and precise medical interventions.

In a society where sustainability is the watchword, Dr Jaidev Kaushik, Assistant Professor at the Department of Chemistry introduces an innovative method for producing acetanilide derivatives, using waste-derived copper flakes as a catalyst. This environmentally friendly approach enables a single-step synthesis while promoting a “waste to wealth” philosophy. His paper titled, “Waste-derived Copper Flakes for Solvent-Free Reductive Acetamidation of Nitroarenes,” featured in the Q1 Journal, Langmuir (ACS).
Abstract:
Amides are the most vital chemical moieties used in organic and biological processes and as a starting material in many industrial sectors like pharmaceuticals, agro-based, polymers, solvents, dyes, pigments, etc. The most common synthesis method of amides is by first reducing nitroarenes to their corresponding amines, followed by acylation with the required acyl group, a two-step process involving expensive metal catalysts. Given this, we have utilized waste-derived copper (Cu) flakes as a cost-effective heterogeneous catalyst for solvent-free and one-pot reductive acylation of nitroarenes. Metallic zerovalent copper flakes (f-ZCu) were isolated from waste copper Cu scrap/flakes/turnings generated after the grinding and cutting from the Cu industries. Moreover, the same procedure was also utilized to produce various substrates, including the gram-scale synthesis of the well-known crucial antipyretic drug, paracetamol.
Practical / Social Implications:
The proposed copper waste-derived heterogeneous catalyst can replace toxic and heavy metal catalysts from various organic synthesis reactions and can be utilized in the large-scale synthesis of important drugs such as paracetamol under more optimized conditions.

It is pivotal for multinational companies to opt for sustainable growth while expanding their domains. In this regard, Dr Manisha Kumari, Assistant Professor from the Department of Management, Paari School of Business, has published her paper titled “The Impact of Corporate Environmental Reporting on the Financial Performance of Listed Manufacturing in Ghana” along with her research scholars Mr Musah Mohammed Saeed and Ms Mohammed Shahin Sultana in the Q1 journal Corporate Social Responsibility and Environmental Management with the impact factor 8.3.
Abstract
A growing number of businesses are facing criticism for engaging in environmentally damaging practices. Despite advancements in technology and operational efficiency, the environmental challenges confronting businesses have become increasingly urgent. As disclosure requirements have expanded, the importance of reporting standards for environmental sustainability has risen. This study explores the impact of corporate environmental reporting on the financial performance of listed manufacturing firms in Ghana. It analyses ten years (2012-2021) of annual reports from 20 publicly traded manufacturing companies, using panel regression and content analysis to assess the data. The findings reveal that environmental sustainability disclosure (ENVD) has a positive and significant effect on return on equity (ROE) and net profit margin (NPM). Furthermore, disclosures related to health, safety, and community development initiatives have a strong positive impact on ROE. The study recommends that policymakers develop guidelines, especially for environmental reporting, to aid firms in preparing their annual reports. It also suggests that corporate accountants expand their expertise and collaborate with environmental and ecological experts. This research offers valuable insights for policymakers and provides a foundation for further investigation into the effects of corporate environmental reporting (CER) on the performance of listed firms in sub-Saharan Africa.
Explanation of the Research in Layperson’s Terms
In simple terms, this study looks at how companies are being criticised for harming the environment, even though they have access to better technology and more efficient ways of working. Environmental problems for businesses are getting more serious, and as governments and organisations require companies to share more information about how they affect the environment, the standards for reporting this information have become more important.
The research focuses on how reporting environmental activities affects the financial success of manufacturing companies in Ghana. It examines reports from 20 publicly traded companies over ten years (2012-2021). The analysis shows that companies that disclose their environmental efforts, such as how they manage health, safety, and community projects, tend to have better financial outcomes, particularly in terms of the profit they return to shareholders and how much profit they make overall.
The study recommends that governments create clear guidelines for environmental reporting to help companies include this information in their annual reports. It also suggests that accountants should work more closely with environmental experts to improve their knowledge. The research provides important information for policymakers and encourages further exploration into how reporting on environmental activities affects company performance in Africa.
Practical Implementation/Social Implications of the Research
The study shows that environmental sustainability disclosures (ENVD) positively impact net profit margin (NPM) and return on equity (ROE) but have minimal effect on return on assets (ROA). This emphasises the need for stricter regulations to ensure comprehensive sustainability reporting, with policymakers incentivising better practices to boost financial performance.
- Energy disclosure (END) positively affects NPM, ROA, and ROE, suggesting mandatory energy-efficiency reporting. Regulators should set standardised metrics and offer tax incentives to encourage energy-efficient technologies.
- Mandatory environmental reporting by companies can help achieve environmental goals, gain importance in securing trade partnerships, and attract global capital.
- Health and safety disclosures (HSD) improve financial metrics, underscoring the need for stricter workplace safety regulations and rewarding safety-focused companies to enhance both worker safety and financial outcomes.
- Community involvement disclosure (CID), which has a negative but insignificant effect on financial performance, highlights the need for standardised reporting and alignment with core business strategies to show long-term value.
- To boost transparency, integrated reporting should be adopted nationwide, embedding environmental and social disclosures into financial reports to better demonstrate their long-term impact. Strengthening Ghana’s weak regulatory framework and aligning it with international standards (e.g., IFRS S1 and S2) would improve corporate social responsibility (CSR) practices, particularly in community development.
- Fiscal incentives, such as tax breaks, could encourage firms to invest in long-term sustainability projects, such as education and healthcare. Capacity building within firms, including sustainability training, would improve both financial and environmental outcomes.
- Standard method of accounting for environmental reporting can bring consistency in the market. Also, they required a proper set of guidelines that can attract environmental investors.
Overall, policy reforms focused on transparency, regulation, and aligning sustainability with financial goals would significantly benefit Ghana’s corporate sector.
Future Research Plans
Dr Manisha plans to shift her focus from traditional accounting standards to the growing field of sustainability reporting. This transition aligns with the increasing global emphasis on environmental, social, and governance (ESG) issues, which have become central to corporate accountability and transparency. Sustainability reporting has been a topic of ongoing discussion, reflecting the need for businesses to disclose not only their financial performance but also their impact on the planet and society.

In this research work, we proposed a fog-enabled network architecture integrated with IoT devices (Intra and Inter-domain IoT devices) and developed the DEAC-IoT scheme using Elliptic Curve Cryptography (ECC) for secure authentication and key agreement. Our protocol is designed to protect device-to-device communication from security threats in resource-constrained IoT environments.

Explanation of the Research in Layperson’s Terms:
With more and more devices connecting wirelessly through the Internet of Things (IoT) (think of smart home gadgets, wearables, etc.), keeping their communications secure has become a big priority. However, many current communication methods for IoT devices don’t provide strong enough security. This leaves them open to cyber-attacks.
The challenge is to create a security system that is safe from attacks and doesn’t require too many computations. This is important because IoT devices often have limited resources (like low battery power or slower processors).
In this research, the authors have devised a solution: a new type of network setup (called fog-enabled architecture) that connects IoT devices with each other and with external devices. They’ve also developed a security protocol called DEAC-IoT, which uses Elliptic Curve Cryptography (ECC)—a highly efficient method for securing communications.
Their system makes it easier for IoT devices to authenticate (verify each other’s identity) and securely exchange keys (used to encrypt data), all while being lightweight enough to run on devices that don’t have a lot of processing power or energy.
In short: the paper offers a way to securely connect IoT devices with minimal computations, making communication between devices safe from hackers, even in environments where cyber threats are common.
Practical Implication and Social Implications Associated:
The practical implementation of this research can strengthen the security of IoT devices across many sectors, from homes and cities to healthcare and industries. The proposed DEAC-IoT scheme can also be used to implement vehicle to vehicle secure communication in autonomous vehicles, VANETs and Internet of Vehicles scenario.
Socially, it can enhance trust in IoT technology, protect privacy, safeguard critical infrastructure, and promote economic and technological development—while ensuring security remains affordable even in resource-constrained environments.
In Industrial IoT (IIoT) Scenario: In industries where machines are connected via IoT (such as in factories), devices need to communicate securely to ensure the smooth running of production lines. The DEAC-IoT protocol could secure these communications, preventing industrial espionage or sabotage.
