This paper aims to examine the interplay between risk, capital and efficiency of Indian banks and study how their relationship differs across different ownership types.

Panel regression techniques are used to analyze a large data set of all Indian scheduled commercial banks operating during the period 2008-2016.

The results show that lower efficiency is associated with higher credit risk in the case of public sector and old private sector banks (”bad management hypothesis”). However, higher efficiency leads to higher credit risk in the case of foreign banks (“cost skimping hypothesis”). The authors further find that the more efficient institutions among public sector hold more capital. Finally, they find that the better-capitalized banks among those in the public sector have lower risks on their balance sheets (“moral hazard hypothesis”).

There is a paucity of papers on the interplay between risk, capital and efficiency of banks in emerging economies. This paper is the first to study the inter-relationship between risk, capital and efficiency of Indian banks across ownership groups using a number of different measures of risk.

Under the traditional franchise value paradigm, competition in banking markets is considered to be risk enhancing because of its tendency to raise interest rates on deposits. Taking a contrarian view, Boyd and De Nicolo (2005) have argued that competition in the loan market can lead to lower interest rates and hence reduce bank risk-taking. Following these contradictory theoretical results, the empirical evidence on the relationship between risk and competition in banking has also been mixed. This paper analyses the competition–stability relationship for the Indian banking sector for the period 1999-2000 to 2012-2013.

Banking competition is measured using structural measures of concentration, namely, five-bank concentration ratios and the Herfindahl-Hirschman Index as well as a non-structural measure of competition – the Panzar-Rosse H-Statistic. Panel regression methods are used to estimate the relationships.

Our results show that while concentration leads to lower levels of default, market and asset risks, it exacerbates the levels of capital and liquidity risks.

These results have interesting implications for banking sector policy in emerging economies. For instance, any strategy on entry of new banks has to be carefully coordinated with supervisory efforts and macro-prudential policy to derive the benefits of greater competition in the banking industry.

This is the first paper that analyses the competition – stability relationship using a large number of alternative measures for the banking sector, an emerging economy.

This study aims to explore the role of the Indian merchant class in 19th-century colonial India in addressing the social concerns of disability. Specifically, it addresses why and how business engaged with disability in colonial India.

This study’s methodology entailed historiographical approach and archival investigation of official correspondence and letters of business people in 19th-century colonial India.

Using institutional theory, the study’s findings indicate that guided by philanthropic and ethical motives, Indian businesses, while recognizing the normative and cognitive challenges, accepted the regulative institutional pressures of colonial India and adopted an involved and humane approach. This manifested in the construction of asylums and the setting up of bequeaths and charitable funds for people with disability (PwD). The principal institutional drivers in making of the asylums and the creation of benevolent charities were religion, social practices, caste-based expectations, exposure to Western education and Victorian and Protestantism ideologies, the emergence of colonial notions of health, hygiene and medicine, carefully crafted socio-political and economic policies of the British Raj and the social aspirations of the native merchant class.

In contrast to the 20th-century rights-based movement of the West, which gave birth to the global term of “disability,” a collective representation of different types of disabilities, this paper locates that cloaked in individual forms of sickness, the identity of PwD in 19th-century colonial India appeared under varied fragmented labels such as those of leper, lunatic, blind and infirm. This paper broadens the understanding of how philanthropic business response to disability provided social acceptability and credibility to business people as benevolent members of society. While parallelly, for PwD, it reinforced social marginalization and the need for institutionalization, propagating perceptions of unfortunate and helpless members of society.

Iodine content in drinking water is a reflection of the iodine level of rocks and soil of the region. Different water sources have different levels of iodine; this makes variability in concentration of iodine content. The present study was done to estimate the iodine content in drinking water from different water sources of Ramtek villages in Nagpur district identified with sporadic cases of endemic goiter. The paper aims to discuss these issues.

The water samples were collected from seven villages from Ramtek taluka, which included well, bore well and tap water. Water was collected in clean and dry glass bottles from each source from the entire villages under study. The analysis of the water samples was done by the method of Karmarkar et al.

Iodine content of water samples varied from 17.42 to 43.55 μg/l in tap water, 17.42-21.77 μg/l in well water and 8.7-37.02 μg/l bore well water. The mean iodine content was found to be highest (34.04±11.44 μg/l) in tap water, while bore well water and well water showed 20.46±14.16 μg/l and 19.59±3.07 μg/l, respectively.

The endemic area has been surveyed by the author – the data generated and analyzed – the findings of which are independently arrived. The study is helpful for students, academicians, independent researchers, and the government policy makers for their further research, policy formulation and implementation.

Quantum-dot cellular automata (QCA) is a promising technology, which seems to be the prospective substitute for complementary metal-oxide semiconductor (CMOS). It is a high speed, high density and low power paradigm producing efficient circuits. These days, most of the smart devices used for computing, make use of random access memory (RAM). To enhance the performance of a RAM cell, researchers are putting effort to minimize its area and access time. Multilayer structures in QCA framework are area efficient, fast and immune to the random interference. Unlike CMOS, QCA multilayer architectures can be designed using active components on different layers. Thus, using multilayer topology in the design of a RAM cell, which is not yet reported in the literature can improve the performance of RAM and hence, the computing device. This paper aims to present the modular design of RAM cell with multilayer structures in the QCA framework. The fundamental modules such as XOR gate, 2:1 multiplexer and D latch are proposed here using multilayer formations with the goal of designing a RAM cell with the provision of read, write, set and reset control.

All the modules used to design a RAM cell are designed using multilayer approach in QCA framework.

The proposed multilayer RAM cell is optimized and has shown an improvement of 20% in cell count, 30% in area, 25% in area latency product and 48.8% in cost function over the other efficient RAM designs with set/reset ability reported earlier. The proposed RAM cell is further analyzed for the fault tolerance and power dissipation.

Due to the multilayer structure, the complexity of the circuit enhances which can be eliminated using simple architectures.

The performance metrics and results obtained establish that the multilayer approach can be implemented in the QCA circuit to produce area efficient and optimized sequential circuits such as a latch, flip flop and memory cells.
