Sampling hurdles : “Borderline Illegitimate” to legitimate data.
No full textIn 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.
No full textThis 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
No full textThis 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
Changing daily-life behaviors to directly cut greenhouse gas emissions
No full textLAUREA MAGISTRALEIl nostro pianeta sta morendo. Il cambiamento climatico è un’emergenza che richiede la nostra massima attenzione urgente. Poiché le attività umane sono aumentate molte volte in passato, dall’inizio della rivoluzione industriale a quella digitale, anche l’impatto sul nostro pianeta Terra. Man mano che la nostra popolazione e tecnologia crescevano, crescevano anche i nostri bisogni. Per soddisfare i nostri bisogni avevamo bisogno di molte risorse naturali che abbiamo estratto ed estratto dal nostro pianeta distruggendo foreste, terre e questo ha disturbato l’equilibrio naturale del nostro ecosistema. A causa dei nostri consumi abbiamo creato molti loop positivi che secondo la teoria del System Design hanno causato conseguenze devastanti. Le attività umane generano gas serra come anidride carbonica, metano, biossido di azoto, ecc. Che rimangono intrappolati nella nostra atmosfera e a causa di questi gas il nostro pianeta si riscalda come una serra. L’aumento della temperatura crea un clima più caldo, un aumento degli eventi meteorologici e disturba l’intero ecosistema naturale del nostro pianeta. Siamo nel periodo della sesta estinzione di massa in cui quasi 200 specie si estinguono ogni giorno.
Secondo il “Rapporto speciale sul riscaldamento globale di 1.5°C” dell’IPCC (gruppo intergovernativo sui cambiamenti climatici), entro il 2030 dovremo ridurre le emissioni globali di gas a effetto serra del 50%. Quindi, mentre l’anno 2019 sta per concludersi dobbiamo ancora raggiungere questi obiettivi che erano stati stabiliti nell’Accordo sul clima di Parigi nel 2015. Ora abbiamo solo il 67% di possibilità di invertire gli impatti e di raggiungere l’obiettivo di limitare l’aumento della temperatura globale a 1.5°C - 2°C.
Tutti i problemi causati dai cambiamenti climatici sono causati dall’uomo. E noi come cittadini della Terra dobbiamo prendere misure drastiche per limitare l’impatto. In quanto individui, in realtà pensiamo di non essere parte del problema e lasciamo il risparmio ai politici e al governo che non hanno fatto nulla per fermare questa catastrofe. In quanto individui, possiamo effettivamente apportare enormi cambiamenti intervenendo a partire dalla comprensione di ciò che facciamo nella vita di tutti i giorni e informandoci sul problema dei cambiamenti climatici. Per una persona media è difficile leggere relazioni scientifiche e documenti di ricerca, quindi esiste una grande opportunità nello sviluppo di un sistema di prodotti e servizi che potrebbe aiutare le persone a essere informate, fare scelte migliori, ridurre il loro impatto e fare la loro parte nella risoluzione di questo problema. Come esseri umani dobbiamo agire e il tempo è adesso.Our planet is dying. Climate Change is an emergency that needs our outmost urgent attention. As human activities have increased many folds in the past from the onset of the industrial revolution to now the digital revolution, so has the impact on our planet Earth. As our populations and technology grew, so did our needs. To fulfil our needs we needed a lot of natural resources that we mined and extracted from our planet by destroying forests, lands and this disturbed the natural balance of our ecosystem. Due to our consumption we have created a lot of positive loops which according to the System Design theory has caused devastating consequences. The human activities generate greenhouse gases such as carbon dioxide, methan, nitrogen dioxide, etc. which gets trapped in our atmosphere and due to these gases our planet warms up like a greenhouse. The temperature rise creates warmer weather, increased weather-related events and disturbs the whole natural ecosystem of our planet. We are now in the period of 6th mass extinction where almost 200 species are getting extinct every single day.
According to the “Special Report on Global Warming of 1.5°C” by IPCC (Intergovernmental Panel on Climate Change), we need to cut down the Global Greenhouse Gas Emissions by 50% by the year 2030. So as the year 2019 is almost ending we still have to achieve this goals which were set at the Paris Climate Agreement in 2015. We just have a 67% chance now to reverse the impacts and to achieve the goal of limiting the global temperature rise to 1.5°C-2°C.
All the problems caused by Climate Change are man-made. And we as citizens of the Earth have to take drastic measures to limit the impact. We as individuals actually think that we are not a part of the problem and leave the saving up to to the politicians and government which haven’t done anything to stop this catastrophe. As individuals we actually can make huge changes by taking action starting by understanding what we do in our day-to-day lives and informing ourselves about the problem of Climate Change. For an average person it is difficult to read scientific reports & research papers so there lies a big opportunity in developing a product-service-system which could help people informed, make better choices, reduce their impact and do their part in solving this problem. As humans we need to take action and the time is now

Racism at work : inter-spouse stress and strain transfer.
No full textThe 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
