This paper aims to report small-signal parameter extraction and simulation of enhanced dual-channel dual-material gate AlGaN/GaN high electron mobility transistor (HEMT) for the first time for the characterization of a device in microwave range of frequency.

For parameter extraction, a standard and well-known direct parameter extraction methodology is applied. Extrinsic elements of small-signal circuit model are extracted from measured S-parameters obtained using pinch-off cold field effect transistor (FET) biasing in the first step at a low frequency range and at a higher frequency range in the second step to ensure higher extraction accuracy. Intrinsic elements are extracted from intrinsic Y-parameters that are obtained after de-embedding all the extrinsic parasitic elements of the device. Figure of merits of radio frequency are also derived from the measured results and S-parameters of the proposed device.

Small signal parameters of the proposed device circuit model are extracted using the standard direct parameter extraction technique. Analysis of microwave figure of merits for device include maximum oscillation frequency, cut-off frequency, current gain, transducer power gain, available power gain, maximum stable gain, transconductance, drain conductance, stern stability factor and time delay.

The paper bridges the gaps between theory and experimental practices by validating extracted results with reported results of structurally matching devices.

An enhanced device structure investigated for small signal parameters incorporates field plate over dual metal engineered gate to provide better electric field uniformity, effective suppression of short channel effect, reduction in current collapse, improvement in carrier transport efficiency and enhancement in drain current capabilities.

Healthcare is indispensable for any civilisation to attain a good quality of life and well-being on both mental and physical levels. The healthcare domain primarily falls under pharma, medical, biotechnology, and nursing. Also, other fields may be aligned with these primary fields. Healthcare amasses the contemporary trends and knowledge of upcoming techniques to improve healthcare processes. The practitioners are primarily doctors, nurses, specialists and health professionals, hospital administrators, and health insurance.

It is a fundamental attribute needed for any society to attain good quality of life and well-being in mental and physical health. It is a fundamental right of people to receive good healthcare where drug treatment and hospitalization are available at a nominal cost, as a requirement of today’s modern era. There appears to be a significant disparity in the availability of good healthcare in rural areas compared to urban in India. Even though we enter the digital era with the facilities offered in Industry 4.0 and other advanced technologies brings about a significant change of overall processing within healthcare systems.

In the present era of green consumerism, consumers are shifting towards sustainable consumption with the rising demand of green products. Despite consumers' demand of such products, their attitudes towards eco-friendly practices can neither be the same for different consumer groups nor can be treated as they all are equally green. The purpose of this study is to operationalize the green market segmentation based on demographic, psychographic and behavioural characterization in the Indian context of green consumerism.

The deductive approach of questionnaire survey method has been adapted to collect the responses from convenience sampling of Indian consumers using the measured constructs concerning to green consumer psychology. The data were analyzed by applying multivariate techniques of confirmatory factor analysis (CFA), cluster and discriminant analysis.

The results revealed that the three distinctive set of consumer groups are evolved as “keen greens”, “moderate greens” and “reluctant greens” based on the eight cognitive variables used in this study, namely environmental concern (EC), perceived environmental knowledge (PEK), perceived consumer effectiveness (PCE), perception of eco-label, perception of eco-brand and environmental advertisements, green purchase intention (GPI) and green purchasing behaviour (GPB) in the Indian context.

The research findings may lack its generalizability in the Indian context, as the survey strategy is confined with the most populated territory of India. To provide its robustness, the future studies need more heterogeneous sample across the country. The research findings could provide the key insights into policymakers and enterprises in the framing of marketing strategies to promote green consumerism in the setting of emerging economies.

There is dearth of literature concerning to green consumer segmentation based on the “attitude–intention–behaviour” approach in the Indian context. Therefore, the present study endeavours to manifest a holistic description of green consumer classification based on demographic, psychographic and behavioural characterization. At Prima facie, the study is the first that elucidates consumers' segments profile by incorporating environmental cognitive factors from both the perspectives; “consumers” inner stimuli' and “external green marketing cues”, especially in the indigenous Indian setting.

Purpose: In this study, an attempt has been made to examine the compliance unit’s role in mediating the electronic government’s role in money laundering. E-government is clarified as the application of Information technology to encourage access and transfer of all aspects of government amenities and operations that impact transparency and accountability for the benefit of the people, trades, workforces and other stakeholders. The current study aims to assess whether the e-government can lessen or counterbalance the risks related to money laundering in the country and the mediating role of the compliance unit in reducing money laundering.

Methodology: This study practices structural modelling to assess the direct linkage between e-government and anti-money laundering and the indirect path between e-government and anti-money laundering that passes through the compliance unit as a mediator.

Findings: The findings prove that the compliance unit fully mediates the relationship between E-government and anti-money laundering. The direct path shows an insignificant relationship between e-government and money laundering, but this association becomes significant when the compliance unit is brought as a mediator.

Originality: This study directs that e-government runs on a sustainable ICT platform to improve transparency and accountability of all aspects of government facilities and actions for sustainable economic goals and help to diminish money laundering by enhancing transparency and accountability of government administration.

This paper aims to critically review the isolation and chemistry of plant pigments.

A literature survey from 1974 to 2022 was carried out and studied thoroughly. The authors reviewed literature in various areas such as isolation methods and catalytic properties of pigments.

With vast growing research in the field of catalytic activities of various pigments like chlorophyll, anthocyanin and flavonoids, there is still scope for further research for the pigments such as Lycopene, carotenoids and xanthophyll as there has not been any significant work in this area.

Plant pigments may be used as an ecofriendly catalyst for chemical reactions.

One can get the direction of pigment research.

Plant pigments are natural and ecofriendly catalyst which can reduce the pollution.

This is an original work. This paper precisely depicts the advantages as well as disadvantages of the isolation techniques of pigments. This study also presents the chemistry of plant pigments.

There has been a substantial increase in the implementation of programmes that aim to enhance the livelihoods of rural people by organizing them into groups, emphasizing women towards achieving women empowerment, which is one of the key goals of the Sustainable Development Goals (SDGs). This study aims to assess the impact of participation in self-help groups (SHGs) under the National Rural Livelihood Mission (NRLM) on the political empowerment of rural tribal women in India.

This study is based on primary data collected using a multistage random sampling method. Field research is conducted in the state of Jharkhand, primarily focusing on women belonging to the scheduled tribe category. The propensity score matching technique derives the results using the psmatch2 command in STATA.

The results show a significant positive change in women's access to voting rights, awareness of various government schemes and entitlements, political awareness and participation, campaigning during elections and leadership positions after participation in SHGs under NRLM.

The existing literature indicates that research on the empowerment of tribal women through participation in SHGs is scant. This study makes a novel contribution by examining the effectiveness of participation in SHGs under NRLM on the political empowerment of tribal women in rural India. This study will provide significant insights to the government, policymakers, practitioners and researchers working on SHGs and tribal women’s empowerment.

After analysing this case study, students will be able to understand the relationship between compensation, reward management and gig workers’ behaviour; apply the theory of organizational behaviour related to compensation management to address the motivational issues; analyse the challenges in managing the gig workers’ expectations related to compensation; and design innovative ways of retaining gig workers, especially delivery partners among the gig workers.

In April 2022, Riya, who worked as a business development manager at a newly established food delivery app company named “Our Kitchen” (located in Hyderabad, India), attended a meeting where the chief executive officer expressed concern about the difficulty in retaining their delivery partners. The company provided food delivery services to the customers by procuring ordered food from partner restaurants in select Indian cities. The delivery partners of the company worked part-time and received a commission for the hours they worked. With the rising fuel cost, minimal career growth and negligible social security benefits, it was hard for them to continue in their jobs. As a result, there were high attrition rates in the food delivery company. This case study is about the attrition issue being faced by the company and explores various strategies through which Riya could think of retaining the delivery partners so that there was a win-win situation for both parties. The dilemma given in the case study would help in understanding the motivational theories and factors that encouraged delivery partners to work for these jobs.

The case study is ideally suited for discussing human resources concepts, especially problems related to the retention of delivery partners without reducing the profit of the organization. It will help in understanding the motivational factors leading to job satisfaction and how that will help in the retention of delivery partners. The case study can also be used to teach the executives in a management development programme. This will help them to understand the gig workers’ motivational factors and the causes of their attrition.
