Variability of thinness and its relation to cardio-metabolic risk factors using four body mass index references in school-children from Delhi, India
No full textObjectives: to compare: (i) prevalences of thinness in school-children by four body mass index references in common use viz., Centre for Disease Control (CDC); Cole; Indian Academy of Pediatrics (IAP); World Health Organization (WHO); and (ii) relationship of thinness with absence of cardio-metabolic risk factors in these BMI references.Design: cross-sectionalSetting: schools in Delhi.Participats: anthropometry and blood pressure were measured in 16,245 school children aged 5 to 18 years. Fasting lipids and blood sugar were estimated in 2796 subjects.Outcome measures: age and sex-specific prevalences of thinness and predictive ability of reference cut-off for detecting any cardio-metabolic risk factor were compared.Results: prevalence of thinness varied with the reference employed; more so for boys. Overall prevalence of thinness was least with IAP reference and highest with CDC cut-offs (6.6% to 16.9% in boys, 6.5% to 10.3% in girls). Children identified as thin by any reference had comparable, significantly lower risks (OR 0.59 to 0.73) of associated cardio-metabolic aberrations. In subjects with any cardio-metabolic or blood pressure aberration, the prevalence of thinness was highest with CDC and least with IAP definition.Conclusions: prevalence of thinness varies considerably with the reference employed. Thin children, identified by any reference, have a lower risk of associated cardio-metabolic aberrations; however, thinness is a poor diagnostic test for this purpose. In populations undergoing nutrition transition, there is a need to link cardio-metabolic risk factors with recommended anthropometric criteria to define undernutritio
Sampling hurdles : “Borderline Illegitimate” to legitimate data.
Get PDFIn this paper the author discusses how sampling access and recruitment problems encountered in an in-depth interview study heightened her sensitivity to “borderline illegitimate” data. The term illegitimate data usually refers to the data collected during a covert study, whereas “legitimate” data are collected during an overt study. Hence, data collected during any nonconsented period(s) of an overt study lie on the borderline of illegitimacy and legitimacy, and constitute what the author calls borderline illegitimate data. Such data need legitimization before use. The borderline illegitimate data were collected during the pre- and postinterview stages of her study as they explained how medical and ethnic cultures and sensitivity to racism as a topic combined to create sample recruitment difficulties of the study. The author later legitimized them by sharing them with the participants, guaranteeing anonymity, and asking their permission to use them
Unpacking the impact of the TikTok ban on local content creators and the rise of Indianized social media apps.
Get PDFThis paper investigates the repercussions of the TikTok ban in 2020 and the subsequent migration of local content creators to alternative platforms, with a particular focus on the identity negotiation of the marginalized LGBTQIA+ community. The author positions this paper as an exploration of the displacement experienced by rural young queers in expressing their queerness following the ban. TikTok was a platform that transcended class barriers and provided an equal platform for socioeconomically diverse users. However, its ban led to the emergence of Indianized social media apps that have further segregated the classes. The author argues that this phenomenon requires academic attention because the rise of these Indian apps coincides with the overshadowing of right-wing populism. By exploring these complex dynamics, this paper contributes to the understanding of the impact of digital media on the social fabric of contemporary India.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/177335/1/15-Garg-Tiktok-Social Media and Society in India Proceedings-66-72-10.73027932.pdfSEL

Leggett-Garg inequalities for quantum fluctuating work
Get PDFThis is the author accepted manuscript. The final version is available from MDPI via the DOI in this recordThe Leggett-Garg inequalities serve to test whether or not quantum correlations in time can be explained
within a classical macrorealistic framework. We apply this test to thermodynamics and derive a set of LeggettGarg
inequalities for the statistics of fluctuating work done on a quantum system unitarily driven in time. It
is shown that these inequalities can be violated in a driven two-level system, thereby demonstrating that there
exists no general macrorealistic description of quantum work. These violations are shown to emerge within the
standard Two-Projective-Measurement scheme as well as for alternative definitions of fluctuating work that are
based on weak measurement. Our results elucidate the influences of temporal correlations on work extraction
in the quantum regime and highlight a key difference between quantum and classical thermodynamics.HM is supported by EPSRC through a Doctoral

Atomic "bomb testing": The Elitzur-Vaidman experiment violates the Leggett-Garg inequality
No full text\ua9 The Author(s) 2018. Elitzur and Vaidman have proposed a measurement scheme that, based on the quantum superposition principle, allows one to detect the presence of an object-in a dramatic scenario, a bomb-without interacting with it. It was pointed out by Ghirardi that this interaction-free measurement scheme can be put in direct relation with falsification tests of the macro-realistic worldview. Here we have implemented the "bomb test" with a single atom trapped in a spin-dependent optical lattice to show explicitly a violation of the Leggett-Garg inequality-a quantitative criterion fulfilled by macro-realistic physical theories. To perform interaction-free measurements, we have implemented a novel measurement method that correlates spin and position of the atom. This method, which quantum mechanically entangles spin and position, finds general application for spin measurements, thereby avoiding the shortcomings inherent in the widely used push-out technique. Allowing decoherence to dominate the evolution of our system causes a transition from quantum to classical behavior in fulfillment of the Leggett-Garg inequality

Racism at work : inter-spouse stress and strain transfer.
Get PDFThe aim of this paper is to discuss pathways that interlink spouses’ well-being in a study of male Indian origin doctors and their wives where husbands experienced racism at work. This first study of its type was underpinned by Collins’ Afro-centric feminist epistemology and Lazarus’ cognitive mediational stress theory. Sampling: A sample of eight couples was recruited through advertising and snowballing. Data collection: Each spouse was interviewed separately through a semi-structured depth interview followed by a telephone interview. Data analysis: Generic pathways that inter-linked spouses’ well-being were delineated through cross-case analysis. Findings: Pathways were found to be grounded in three areas: a) supportive behaviour of the wives, b) the nature of inter-spouse communication, and c) the husband’s behaviour with the couple’s children. These pathways were accentuated by the couples’ values and beliefs related to Hinduism and middle-class, and doctors’ personality characteristics
