Neuroethics Questions to Guide Ethical Research in the International Brain Initiatives.K. S. Rommelfanger,S. J. Jeong,A. Ema,T. Fukushi,K. Kasai,K. M. Ramos,Arleen Salles,I.Singh,Paul Boshears,Global Neuroethics Summit Delegates &Hagop Sarkissian -2018 -Neuron 100 (1):19-36.detailsIncreasingly, national governments across the globe are prioritizing investments in neuroscience. Currently, seven active or in-development national-level brain research initiatives exist, spanning four continents. Engaging with the underlying values and ethical concerns that drive brain research across cultural and continental divides is critical to future research. Culture influences what kinds of science are supported and where science can be conducted through ethical frameworks and evaluations of risk. Neuroscientists and philosophers alike have found themselves together encountering perennial questions; these questions are (...) engaged by the field of neuroethics, related to the nature of understanding the self and identity, the existence and meaning of free will, defining the role of reason in human behavior, and more. With this Perspective article, we aim to prioritize and advance to the foreground a list of neuroethics questions for neuroscientists operating in the context of these international brain initiatives.

A double‐edged sword to force posterior dominance of Hox genes.Narendra PratapSingh &Rakesh K. Mishra -2008 -Bioessays 30 (11-12):1058-1061.detailsSpatially and temporally restricted expression of Hox genes requires multiple mechanisms at both the transcriptional and the post-transcriptional levels. New insight into this precise expression mechanism comes from recent findings of a novel sense–antisense miRNA combination from the bithorax complex of Drosophila melanogaster.1-4 These two miRNAs encoded from the same locus target 3′ untranslated regions of anterior hox genes, Antp, Ubx and abd-A to establish the dominance of posterior hox gene Abd-B in its expression domain. Such double-edge tools, sense–antisense miRNA (...) combinations, also operate at multiple loci in the genome implicating their wider impact on the post-transcriptional gene regulation in eukaryotes.

Labour standards in global value chains in India: the case of handknotted carpet manufacturing cluster.S. P.Singh &Amit K. Giri -2016 -Asian Journal of Business Ethics 5 (1 - 2):37-52.detailsIndia is a major producer and exporter of hand-knotted carpets to the world since the beginning of the British rule over India. Majority of the hand-knotted carpets exported from India are produced in the Bhadohi-Mirzapur region, popularly called as the carpet belt of India. Given deplorable working conditions and very high prevalence of child labour in the cluster, in the mid-1990, four social labels were implemented to improve the labour standards, in addition to slew of labour laws implemented by the (...) state of India. The objective of this study is to explore the prevailing labour standards and effectiveness of social labels in improving labour standards in the hand-knotted carpet manufacturing cluster. This study found that even after the implementation of social labels and slew of labour laws, there had been barely any improvement in the working conditions of carpet workers. The workers continued to be adversely incorporated in the carpet commodity chain. However, realising that there is very little scope of social upgrading in this occupation, many carpet workers have shifted to other occupations. But this study found very few child workers in carpet manufactories in the cluster. (shrink)
Chromosome segment duplications in Neurospora crassa: barren crosses beget fertile science.Parmit K.Singh,Srividhya V. Iyer,Mukund Ramakrishnan &Durgadas P. Kasbekar -2009 -Bioessays 31 (2):209-219.detailsStudies on Neurospora chromosome segment duplications (Dps) performed since the publication of Perkins's comprehensive review in 1997 form the focus of this article. We present a brief summary of Perkins's seminal work on chromosome rearrangements, specifically, the identification of insertional and quasiterminal translocations that can segregate Dp progeny when crossed with normal sequence strains (i.e., T × N). We describe the genome defense process called meiotic silencing by unpaired DNA that renders Dp‐heterozygous crosses (i.e., Dp × N) barren, which provides (...) a basis for identifying Dps, and discuss whether other processes also might contribute to the barren phenotype of Dp × N and Dp × Dp crosses. We then turn to studies suggesting that large Dps (i.e., >300 kbp) can allow smaller gene‐sized duplications to escape another genome defense process called repeat‐induced point mutation (RIP), possibly by titration of the RIP machinery. Finally, we assess whether in natural populations dominant RIP suppressor Dps provide an “RIP‐free” niche for evolution of new genes following the duplication of existing genes. (shrink)
Religious Diversity at Workplace: a Literature Review.Reetesh K.Singh &Mansi Babbar -2021 -Humanistic Management Journal 6 (2):229-247.detailsThe globalization, increased migration, and mobility of workforce necessitate the need to study religious diversity in organizations, which has not yet received adequate academic attention of management scholars. The paper attempts to define and understand the nuances of religious diversity with the help of certain theories from psychology and sociology domains. It aims to present the legal provisions of different countries regarding workplace religious discrimination and endeavours to synthesize and analyze the pros and cons of religious diversity at workplace. The (...) paper follows a systematic literature review approach. The descriptive analysis of search results and thematic analysis of the literature reviewed has been presented. It is found that the theories from other domains can be borrowed to understand the root cause of different perceptions for religious diversity. The favourable and unfavourable outcomes of workplace religious diversity have been identified and categorized at two levels i.e. individual and organizational. It is realized that the favourable outcomes of bringing religion to workplace outnumber the unfavourable outcomes and therefore it is time to leverage workplace religious diversity. Lastly, the paper attempts to equip the human resource managers with certain strategies to better deal with religious diversity issues at the workplace. (shrink)
Classification of Infant Cries Using Dynamics of Epoch Features.Kapinaiah Viswanath,K. Sreenivasa Rao,Jayanta Mukhopadhyay &Avinash KumarSingh -2013 -Journal of Intelligent Systems 22 (3):351-364.detailsIn this article, epoch-based dynamic features such as sequence of epoch interval values and epoch strength values are explored to classify infant cries. Epoch is the instant of significant excitation of the vocal tract system during the production of speech. For voiced speech, the most significant excitation takes place around the instant of glottal closure. The different types of infant cries considered in this work are hunger, pain, and wet diaper. In this work, epoch strength and epoch interval features are (...) used to represent infant cry-specific information from the acoustic signal. In this study, the proposed features such as epoch interval and epoch strength values are determined using zero-frequency filter-based method. Gaussian mixture models are used to classify the above-mentioned cries from the features proposed in this work. GMMs are developed separately for each of the cries using the proposed features. The infant cry database collected under a telemedicine project at the Indian Institute of Technology Kharagpur has been used for this study. In the first step, infant cry recognition accuracy is investigated separately using epoch interval and epoch strength features. To enhance recognition performance, GMMs developed using various features are combined through score level fusion techniques. The recognition performance using a combination of evidence is found to be superior over individual systems. (shrink)

Philosophy of Change Management.S. K.Singh -2008 -Proceedings of the Xxii World Congress of Philosophy 29:157-163.detailsThe persons who adapt to changes as may be necessary in the course of their existence not only survive in the struggle for existence but also thrive and enjoy their lives in the best possible way under the given circumstances. For, life consists in various relationships, which are in constant movement and change.Therefore dealing with change or change-management has got pivotal importance in all walks of humans’ lives. In order to facilitate smooth change all big and small inheritances have to (...) be shed off. Adaptation to change involves some amount of give and take. Before stepping into new shoes one has to remove old ones. Sticking to good or bad things of the past in some cases spoils the present. One should, therefore, be in a position to come out of the situation of status quoor inertia. In some cases our ego does not allow us to change. It forces us to remain in the state that we have been enjoying hitherto. If we are untouched by sense of exuberance and live a life of simplicity, we can break the fetters of ego. The crux of the problem lies in affecting the change of attitude towards the present state of affairs and performance of corresponding duty. The persons should realize that change in power, position, strength etc. is inevitable. So,they should be mentally and physically prepared for it. This can be conveniently achieved by developing adaptability to and management of change. (shrink)

Cerebellar Abnormalities on Proton MR Spectroscopy and Imaging in Patients With Gluten Ataxia: A Pilot Study.Vishwa Rawat,Ritu Tyagi,InderSingh,Prasenjit Das,Achal Kumar Srivastava,Govind K. Makharia &Uma Sharma -2022 -Frontiers in Human Neuroscience 16.detailsGluten ataxia is a rare immune-mediated neurological disorder caused by the ingestion of gluten. The diagnosis is not straightforward as antibodies are present in only up to 38% of patients, but often at lower titers. The symptoms of ataxia may be mild at the onset but lead to permanent damage if remain untreated. It is characterized by damage to the cerebellum however, the pathophysiology of the disease is not clearly understood. The present study investigated the neurochemical profile of vermis and (...) right cerebellum and structural changes in various brain regions of patients with gluten ataxia and compared it with healthy controls. Volumetric 3-D T1 and T1-weighted magnetic resonance imaging in the three planes of the whole brain and single-voxel 1H- magnetic resonance spectroscopy of the vermis and right cerebellum were acquired on 3 T human MR scanner. The metabolite concentrations were estimated using LC Model while brain volumes were estimated using the online tool volBrain pipeline and CERES and corrected for partial volumes. The levels of neuro-metabolites were found to be significantly lower in vermis, while N-acetyl aspartate + N-acetyl aspartate glutamate and glycerophosphocholine + phosphocholine was lower in cerebellum regions in the patients with gluten ataxia compared to healthy controls. A significant reduction in the white matter of ; reduction in the volumes of cerebellum lobe and thalamus while lateral ventricles were increased in the patients with gluten ataxia compared to healthy controls. The reduced neuronal metabolites along with structural changes in the brain suggested neuronal degeneration in the patients with gluten ataxia. Our preliminary findings may be useful in understanding the gluten-induced cerebral damage and indicated that MRI and MRS may serve as a non-invasive useful tool in the early diagnosis, thereby enabling better management of these patients.

Of Semiotics, the Marginalised and Laws During the Lockdown in India.Manwendra K. Tiwari &SwatiSingh Parmar -2022 -International Journal for the Semiotics of Law - Revue Internationale de Sémiotique Juridique 35 (3):977-1000.detailsOn 24th March 2020, the first nationwide complete lockdown was announced by the Prime Minister of India for 21 days which was later extended to 31st May 2020. Consequently, thousands of migrant workers placed in big cities had no other option but to go back to their native villages. Their journeys back to villages- thousands of kilometres on bicycles or foot due to the non-availability of public transport amidst the travel ban- were driven by the compulsions of food and shelter. (...) In one of many heart-wrenching incidents, sixteen laborers were run over by a freight train while they were resting on the railway tracks. The images of the Roti on the railway track strewn across were beamed on the national news channels, as a telling commentary of the unimaginable hardships of these workers. Ironically, in the eyes of law, they were trespassers under the Indian Railways Act, 1989. The Indian Railway did not pay any compensation to the victims. Their act also violated the Indian Disaster Management Act, 2005 and Indian Penal Code, 1860- the law for the breach of lockdown guidelines and the law for disobedience of order by public servants respectively- for having decided to travel amidst a travel ban. The semiotics of law-making acts ‘criminal’ bereft of ‘moral culpability’ are seldom questioned on their supposed amoral foundations. Pandemic exhibited that social fissures not only condition the individual or community actions but also the actions of the State. Minorities especially Muslims were at the receiving end of State’s selective enforcement of lockdown laws in India. The various instances in the wake of the COVID-19 pandemic expose the hollow claims of equality before the law and the equal protection of laws as a constitutional promise to every citizen. This article aims to unravel the ostensible and the actual moral exhibition of such Indian laws through the lens of several incidents during the nationwide lockdown in India. This paper would argue that this constructed positivist amorality needs to be deconstructed to unearth the power imbalance that it seeks to hide. (shrink)
