International health-related research on human subjects entails unique ethical responsibilities and difficulties. Often, these difficulties are augmented by the lack of a local ethical review infrastructure. In a recent cross-national study conducted by us, three critical components of ethical regulation were identified—external oversight, local oversight and subject involvement—and integrated into the study design. These three concepts are outlined and established as an important aspect of ensuring ethical coherence in the local context, particularly when reviews by the local institutional review boards (...) cannot practically be obtained. The three levels of ethical oversight identified are suggested to be the framework within which future field studies on human subjects are developed and a standard for maintaining ethical rigorousness in research on humans.

BackgroundCognitive deficits are one of the core features of major depressive disorder that play crucial role in functional recovery. Studies have explored cognitive deficits in MDD, however, given inconsistent results, especially in mild-moderate MDD. Recently, studies have explored music as cognitive ability in various clinical conditions. In MDD, large focus has been on evaluating emotion deficits and just a handful on music cognition. With growing evidence on use of music based intervention to target cognitive deficits, it is imperative to explore (...) nature of music cognitive ability in MDD.AimTo examine musical and neuro-cognitive deficits in patients with mild-moderate MDD.MethodsPatients diagnosed with mild or moderate MDD and matched healthy controls were evaluated on selected tests from NIMHANS Neuropsychological test battery and Montreal battery for evaluation of amusia.ResultsMDD group performed significantly lower than HC on working memory, verbal learning and retention. Three indices were computed for a comprehensive evaluation. Groups did not differ significantly in any of the indices- focused attention, executive function, learning and memory as well as on music cognition. Focused attention and memory index predicted music cognition in HC and the combined group. Attention alone contributed to 62.1% of variance in music cognition. Similarly, music cognition significantly predicted focused attention.ConclusionIndividuals with mild-moderate MDD show significant deficits in working memory, verbal learning and memory, however, not in music cognition. There exists a significant relationship between music cognition and attention, which could be implicated in use of music interventions to ameliorate cognitive deficits. Limitations of study include small sample size and heterogeneity. Future studies on larger cohort examining musical emotion perception and neurocognition is imperative to have deeper understanding of this debilitating condition. (shrink)

Brief summary of the adhikaranas of Brahamasūtra of Bādarāyaṇa.

In this paper, we propose a person verification scheme using a novel combination of palmprint and speech. The crucial aspect of biometric based verification lies in its use of features in verification. Thus, in this paper, we propose two novel feature extraction methods for palmprint verification. The proposed methods are based on the Gaussian mixture model followed by subspace based approaches such as ICA I and ICA II, called independent component analysis I mixture model and independent component analysis II mixture (...) model for palmprint verification. The speech verification system uses sphericity based measurement for person verification. The proposed multimodal biometric system uses a fairly large database of 150 users. The robustness of the proposed methods is validated by introducing six different types of noises on palmprint images and Gaussian white noise with two different signal-to-noise ratios on speech samples. Then, fusion of palmprint and speech are carried out at match score level using the weighted SUM rule for both clean and noisy conditions. Finally, we compare the results of combined biometric with the results of individual biometric and also the results of the proposed methods against conventional subspace methods. (shrink)

In this paper, we propose a general copula approach to accommodate non-normal continuous mixing distributions in multinomial probit models. In particular, we specify a multivariate mixing distribution that allows different marginal continuous parametric distributions for different coefficients. A new hybrid estimation technique is proposed to estimate the model, which combines the advantageous features of each of the maximum simulated likelihood inference technique and Bhat’s maximum approximate composite marginal likelihood inference approach. The effectiveness of our formulation and inference approach is (...) demonstrated through simulation exercises and an empirical application. (shrink)

Animal personality refers to the consistency of variation in behavior among individuals which may be the driving force behind variations in complex behaviors as well. Individual personality could predict how well an organism would perform in behavior and cognition related tasks, as well as survive and thrive in its environment. Therefore, we would expect inter-individual variations in many behaviors, which would persist even if habituation to the experimental setup occurs, which generally results in convergence of behavior. Our study used wild-caught (...) zebrafish from three natural habitats with differing ecological regimes, to understand how consistency and repeatability in specific traits such as boldness, exploration, and spatial ability varies across and within populations even when habituation causes change in behavior. We found that the extent of individual variation differs between populations, with dynamic habitats showing similar repeatability. This indicates that habitat conditions are important drivers of individual variation in addition to other factors, such as sex or size of individuals within populations. Although we found that sex and size played an important role within some populations for some behaviors, in others, the variation was likely caused by other factors, for which we have not accounted. This study underlines the importance of studying inter-individual differences as the phenomenon that underpins multiple behavioral traits and explains the possible role of environmental and inherent factors that drive these differences.

Six treatises on the textual contents of Badarāyana's Brahmasutras, a work of Vedanta philosophy.

This study attempts to fill in two research gaps in the extant literature concerning the ecosystem for social innovation in the context of emerging market economies such as India. The study first attempts to assess the potential of corporate social responsibility (CSR) in not-for-profit entities such as technology business incubators (TBIs) to stimulate social innovations in the prevalent ecosystems in emerging markets. Further, using a random-effects Tobit model, the study examines the characteristics of firms that spend higher percentages of CSR (...) expenditure on not-for-profit TBIs/societies/trusts in India. The study provides policy suggestions to create an entrepreneurial ecosystem for promoting social innovation in emerging markets such as India. (shrink)

Pashmina is one of the most luxurious and finest fibres in the world. It is a special kind of wool obtained from Cashmere goats. Counterfeiting Pashmina is becoming a prevalent malpractice because of limited supply, expensive pricing and high demand in western markets. Presently, there is a lack of a low-cost and easily available approach for distinguishing authentic Pashmina apparels from other similar-looking products. Because of technological advances and cost reductions in digital image processing, we have been able to implement (...) a variety of image recognition systems on a practical level. In this study, we propose a deep learning model PashmNet for identification of Pashmina fabric using transfer learning. The technique proposed herein classifies Pashmina and non-Pashmina images accurately with classification accuracy of 97.4%. (shrink)

Flavin‐containing monooxygenases (FMOs), traditionally known for detoxifying xenobiotics, are now recognized for their involvement in endogenous metabolism. We recently discovered that an isoform of FMO, fmo‐2 in Caenorhabditis elegans, alters endogenous metabolism to impact longevity and stress tolerance. Increased expression of fmo‐2 in C. elegans modifies the flux through the key pathway known as One Carbon Metabolism (OCM). This modified flux results in a decrease in the ratio of S‐adenosyl‐methionine (SAM) to S‐adenosyl‐homocysteine (SAH), consequently diminishing methylation capacity. Here we discuss (...) how FMO‐2‐mediated formate production during tryptophan metabolism may serve as a trigger for changing the flux in OCM. We suggest formate bridges tryptophan and OCM, altering metabolic flux away from methylation during fmo‐2 overexpression. Additionally, we highlight how these metabolic results intersect with the mTOR and AMPK pathways, in addition to mitochondrial metabolism. In conclusion, the goal of this essay is to bring attention to the central role of FMO enzymes but lack of understanding of their mechanisms. We justify a call for a deeper understanding of FMO enzyme's role in metabolic rewiring through tryptophan/formate or other yet unidentified substrates. Additionally, we emphasize the identification of novel drugs and microbes to induce FMO activity and extend lifespan. (shrink)

This article seeks to examine the representation of masculinities and femininities in the renowned South Indian drama film The Great Indian Kitchen. The research construes the manner in which the two dominant genders promote and/or modify patriarchal norms within the institution of family. The functioning of women as ancillary members of patriarchy, the interplay between masculinities and femininities, their evolution in contemporary times, etc., are also critically engaged in the paper. The paper argues that the movie The Great Indian Kitchen (...) not only illustrates different masculinities and femininities but also reconstructs the patriarchal family structure which institutionalises gender inequality. It further argues that the movie proposes an alternative image of the family based on gender equality, where men and women live with mutual respect and complementation. (shrink)

The relatively simple central nervous system (CNS) of the Drosophila embryo provides a useful model system for investigating the mechanisms that generate and pattern complex nervous systems. Central to the generation of different types of neurons by precursor neuroblasts is the initial specification of neuroblast identity and the Drosophila segment polarity genes, genes that specify regions within a segment or repeating unit of the Drosophila embryo, have emerged recently as significant players in this process. During neurogenesis the segment polarity genes (...) are expressed in the neuroectodermal cells from which neuroblasts delaminate and they continue to be expressed in neuroblasts and their progeny. Loss-of-function mutations in these genes lead to a failure in the formation of neuroblasts and/or specification of neuroblast identity. Results from several recent studies suggest that regulatory interactions between segment polarity genes during neurogenesis lead to an increase in the number of neuroblasts and specification of different identities to neuroblasts within a population of cells.
