The purpose of this paper is to examine the growth and characterization of the two different compound semiconductors, namely, n-zinc oxide (ZnO) and p-gallium antimonide (GaSb). In this paper, fabrication and characterization of n-ZnO/p-GaSb heterojunction diode is analyzed.

Thermo vertical direction solidification (TVDS) method was used to synthesize undoped GaSb ingot from high purity Ga (5N) and Sb (4N) host materials. Thermal evaporation technique is used to prepare a film of GaSb on glass substrate from the pre-synthesized bulk material by TVDS method. Undoped ZnO film was grown on GaSb film by sol–gel method by using chemical wet and dry (CWD) technique to fabricate n-ZnO/p-GaSb heterojunction diode.

The formation of crystalline structure and surface morphological analysis of both the GaSb bulk and film have been carried out by x-ray diffraction (XRD) analysis and scanning electron microscopy analysis. From the XRD studies, the structural characterization and phase identification of ZnO/GaSb interface. The current–voltage characteristic of the n-ZnO/p-GaSb heterostructure is found to be rectifying in nature.

GaSb film growth on any substrate by thermal evaporation method taking a small piece of the sample from the pre-synthesized GaSb bulk ingot has not been reported yet. Semiconductor device with heterojunction diode by using two different semiconductors such as ZnO/GaSb was used by this group for the first time.

This study aims to examine the value relevance of earnings in terms of predicting the value variables such as cash flow, capital investment (CI), dividend and stock return under the Indian institutional settings.

The study used panel Granger causality tests to examine causality relationships among variables and panel data regression models to check the statistical associations between earnings and value variables.

Based on a data set of 7,280 Bombay Stock Exchange-listed firm-years spanning over ten years from March 2009 to March 2018, the results show higher sensitivity of earnings toward cash flows, CI, divided and stock return and vice-versa. Further, the findings deduced from the empirical results demonstrate that earnings are positively related to value variables. Overall, the results established that earnings are value-relevant and have predictive ability to forecast the value variables that facilitate investors in portfolio valuation. The results are consistent with the predictive view of the value relevance of earnings. Several robustness checks confirm these results.

This study brings new empirical evidence from a distinct capital market, India, and provides a new facet to the value relevance debate in terms of its prediction view. The study is among earlier attempts that jointly measure the ability of earnings in forecasting different value variables by taking a uniform sample of firms at the same period. Hence, the study provides a comprehensive view of the predictive ability of reported earnings.

This paper aims to provide an overview of recent research on accountability of local and state governments in India.

The Downsian theory of electoral competition is used as a departure point for classifying different sources of government accountability failures. Subsequent sections deal with each of these sources in turn: limited voter participation and awareness; ideology, honesty and competence of political parties and electoral candidates; capture by elites; clientelism and vote-buying. Each section starts by explaining the relevant departure from the Downsian framework and then reviews available empirical evidence in the Indian context for each of these possible “distortions”, besides effects of related policy interventions. The final section summarizes the lessons learnt, and the fresh questions that they raise.

The paper describes a range of possible reasons that limit the effectiveness of elections as a mechanism inducing governments to be accountable to their citizens and reviews the evidence available from the Indian context concerning each of these.

The contribution of the paper is to provide an overview and perspective of recent literature on political economy problems affecting performance of state and local governments in India.

This paper analyzes the welfare implications of the unequal distribution of wealth amongst the social and religious groups by studying the segregation of these groups across different occupations.

The authors use measures suggested by Alonso-Villar and Río (2017) and del Río and Alonso-Villar (2018) to compute the well-being of social groups (based on caste system prevalent in the Indian subcontinent) and religious groups due to their segregation across different regions (urban and rural) and occupations and social welfare loss of the society due to the segregation. Here social groups comprise of ST: Scheduled Tribe, SC: Scheduled Caste, OBC: Other Backward Caste and Others: other remaining castes; while, religious groups comprise of followers of Hinduism, Islam, Christianity and other religious groups.

The result shows that SC and ST groups are worse; while, the “others” group is better off due to the segregation of social groups across both regions and occupation. Similarly, in the case of religious groups, the analysis reveals that followers of Christianity are better off due to the segregation across region and occupation. It further shows that followers of Hinduism are negatively impacted while followers of Islam and other religious groups were better off due to the segregation across the regions.

Various researchers have studied the wealth inequality and unequal distribution in India over the years but did not dive further into the welfare implications of segregation of social and religious groups from wealth perspectives in India.

There is limited evidence on the determinants of hospitalisation and its causes in India. This study aims to examine the differential in the hospitalisation rates and its socioeconomic determinants. This study also examines the causes of diseases in hospitalisation among the elderly (≥60 years) in India.

This study used data from the 75th round of the National Sample Survey Organizations, collected from July 2017 to June 2018. The elderly samples in this survey are 42,759, where 11,070 were hospitalised, and 31,689 were not hospitalised in the past year or 365 days. This study estimated hospitalisation rates and carried out binary logistic regression analysis to examine the associations of hospitalisation with the background variables. The cause of diseases in hospitalisations was also calculated.

The hospitalisation rate was lower among elderly female compared to elderly male. Elderly who belongs to middle-old aged groups, non-married, North-Eastern region, Southern region, general caste, health insurance, partially and fully economically dependent have a higher chance of being hospitalised. About 38% elderly were hospitalised due to communicable diseases (CDs), 52% due to non-communicable diseases (NCDs) and 10% due to injuries and others (IO). Nearly 40% elderly were hospitalised in public hospitals due to CDs, whereas 52% were hospitalised in private hospitals due to NCDs and 11% due to IO.

Firstly, this study is based on cross-sectional survey due to which temporal ambiguity averted to draw causal inferences. Secondly, other significant factors can also predict hospitalisations and provide insightful results, such as lifestyle factors, behavioral factors, obesity, mental state and several personal habits such as smoking cigarettes, drinking alcohol, consuming tobacco or other harmful substances. But this information was not available in this study. Even with these limitations, the hospitalisation issues among the elderly are beneficial to understand the current circumstances of CDs, NCDs and injury and other diseases for India and its states to formulate health policy.

Early screening and early treatment for NCDs are needed, which are non-existent in almost all parts of India. It is essential to necessitate and identify the important factors that best predict hospitalisation or re-visit of hospital admission. Although, the medical advances in India have made rapid strides in the past few decades, it is burdened none the less, as the doctor–patient ratio is very low. It is important to develop preventive measures to minimize the accidents and causalities to avoid substantial cost associated with elderly health care.

Raising awareness, promotion of healthy life style and improving the quality of good health-care provisions at primary level is a necessity.

The findings, practical and social implications provide a way forward for the health policymakers to potentially alter the future research to reduce associated comorbidities, unnecessary hospitalisations and other medical complications.

The paper demonstrates prejudicial effects of the rising private participation and the lacuna of state in ensuring the accessibility and affordability of healthcare.

Secondary data analysis from national and international databases is employed to demonstrate the low government spending and the alternate healthcare financing mechanisms in the country. The company reports of six Indian pharma companies are examined to map the profits and revenues, and also taking into account the sales growth and return on investment.

The paper observes the pharmaceutical sector, via its spiralling drug prices, is the primary contributor to the huge out-of-pocket expenses borne by households. The study findings indicate that there is an increased divergence between the out-of-pocket expenses of households and exorbitant profits of the private drug companies in the country over the years.

Amidst debates on the importance of public health in the aftermath of the pandemic, the paper examines the rising hands of private sector in healthcare, and implores – who benefits? The authors study the implications via looking into the rise in the wealth of pharma giants; at the time of crisis when the lives of common citizens in the country were at stake.

The paper emphasises the repercussions of the higher markup of the pharma industry in raising the healthcare costs of households. The authors emphasise that the nonregulation of the pharma sector leads to high medical debts/poverty, in the wake of growing out-of-pocket expenditures of the citizens.

With technology advances, metallic implants claim to improve the quality and durability of human life. In the recent decade, Ti-6Al-4V biomaterial has been additively manufactured via selective laser melting (SLM) for orthopedic applications. This paper aims to provide state-of-the-art on mechanobiology of these fabricated components.

A literature review has been done to explore the potential of SLM fabricated Ti-6Al-4V porous lattice structures (LS) as bone substitutes. The emphasize was on the effect of process parameters and porosity on mechanical and biological properties. The papers published since 2007 were considered here. The keywords used to search were porous Ti-6Al-4V, additive manufacturing, metal three-dimensional printing, osseointegration, porous LS, SLM, in vitro and in vivo.

The properties of SLM porous biomaterials were compared with different human bones, and bulk SLM fabricated Ti-6Al-4V structures. The comparison was also made between LS with different unit cells to find out whether there is any particular design that can mimic the human bone functionality and enhance osseointegration.

The implant porosity plays a crucial role in mechanical and biological characteristics that relies on the optimum controlled process variables and design attributes. It was also indicated that although the mechanical strength (compressive and fatigue) of porous LS is not mostly close to natural cortical bone, elastic modulus can be adjusted to match that of cortical or cancellous bone. Porous Ti-6Al-4V provide favorable bone formation. However, the effect of design variables on biological behavior cannot be fully conclusive as few studies have been dedicated to this.
