Meanings of Failed Action: A Reassessment of the 1946 Royal Indian Navy Uprising

The exhibition Meanings of Failed Action: Insurrection 1946 opened in Mumbai on 17 March 2017 and in New Delhi on 8 February 2018. The second part of Vivan Sundaram’s The History Project,1 this new installation was intended to mark seventy years of Indian independence and partition by exploring an often forgotten moment of Indian history: the uprising of the Royal Indian Navy’s ratings in February 1946, when 10,000 naval ratings took charge of 66 ships across the Indian subcontinent in the name of the ‘Quit India’ movement. R.I.A.F. men, Sepoys, Bombay’s industrial workers and the city’s population joined in, marching in solidarity with the ratings irrespective of caste and religious affiliation. But the Congress and the Muslim League condemned the action and consented to British military intervention, which resulted in the deaths of over two hundred people and the ratings’ imprisonment. The event has since been erased from Indian national history, perhaps because, had the insurrection succeeded, India’s struggle for freedom might have taken a different turn. I worked on the exhibition as a researcher for the artist, with Ashish Rajadhyaksha and David Chapman, for over a year. The question we sought to answer during those months was: what is the significance of that uprising for India today? With this question in mind, in what follows I focus on the documents we unearthed in the process – pamphlets, slogans, the ratings’ statements to the police and Inquiry, their memories and prison letters – and examine the motivations and hopes that defined the strikers’ action. What kind of freedom did the ratings stand for

The Women’s Royal Indian Naval Service: Picturing India’s New Woman

Lack of research on the Women’s Royal Indian Naval Service (W.R.I.N.S.) has led to the misconception that most of the women recruited into the Royal Indian Navy during World War 2 were either British or ‘Anglo-Indian’. In reality, by far the majority of the ‘Wrins’, as they came to be called, were Indian. In this paper I follow two parallel lines of enquiry. The first inspects the material stored in British archives - official navy documents, illustrated promotional pamphlets, photographs, memoirs, oral history and letters - to offer the first comprehensive account of the W.R.I.N.S.’ formation, operation and dismantlement. This provides the context for an examination of the visual material created to promote the service. More specifically, comparing the few surviving photographs of Wrins with Lee Miller’s photos of Wrens, I argue that W.R.I.N.S. material mediated a specific and, for the time, new set of discourses about Indian women, ideas about women’s role in a nation-in-making that may still speak to Indian women today

Systematic Field-Theory for the Hard-Core One-Component Plasma

An accurate and systematic equation of state for the hard-core one-component plasma (HCOCP) is obtained. The result is based on the Hubbard-Schofield transformation which yields the field-theoretical Hamiltonian, with coefficients expressed in terms of equilibrium correlation functions of the reference hard-core fluid. Explicit calculations were performed using the Gaussian approximation for the effective Hamiltonian and known thermodynamic and structural properties of the reference hard-core fluid. For small values of the plasma parameter G and packing fraction the Debye-Huckel result is recovered, while for G>>1, the excess free energy F_ex and internal U_{ex} energy depend linearly on G. The obtained expression for U_ex is in a good agreement with the available Monte Carlo data for the HCOCP. We also analyse the validity of the widely used approximation, which represents the free energy as a sum of the hard-core and electrostatic part.Comment: 14 pages, 3 figure

Hospital environment as a reservoir for cross transmission. Cleaning and disinfection procedures

Background. Healthcare associated infections (HAIs) represent a serious problem for public health, as they increase the morbidity and mortality rates, present a relevant financial burden, and significantly contribute to the antimicrobial resistance. Methods. The aim of this review was to investigate the literature about HAIs, with particular reference to hospital environments and the role of cleaning and disinfection procedures. Hospital environments are an essential reservoir for HAIs cross transmission, and the application of appropriate procedures related to hand hygiene and disinfection/sterilization of surfaces and instruments remain key strategies for controlling HAIs. Results. Different procedures, based on the risk associated with the healthcare procedure, are recommended for hand hygiene: washing with soap and water, antiseptic rubbing with alcohol-based disinfectants, antiseptic and surgical hand washing. Environmental surfaces can be treated with different products, and the mostly used are chlorine-based and polyphenolic disinfectant. The reprocessing of instruments is related to their use according to the Spaulding's classification. In addition, scientific evidence demonstrated the great relevance of the "bundles" (small set of practices performed together) in controlling HAIs. Conclusions. Research agenda should include the improvement of well-known effective preventive procedures and the development of new bundles devoted to high-risk procedures and specific microorganisms

Phase noise measurement in a cavity with a movable mirror undergoing quantum Brownian motion

We study the dynamics of an optical mode in a cavity with a movable mirror subject to quantum Brownian motion. We study the phase noise power spectrum of the output light, and we describe the mirror Brownian motion, which is responsible for the thermal noise contribution, using the quantum Langevin approach. We show that, contrary to what has been claimed in the recent literature, the standard quantum Langevin equations provide an adequate and consistent description of Brownian motion

Increasing future gravitational-wave detectors sensitivity by means of amplitude filter cavities and quantum entanglement

The future laser interferometric gravitational-wave detectors sensitivity can be improved using squeezed light. In particular, recently a scheme which uses the optical field with frequency dependent squeeze factor, prepared by means of a relatively short (~30 m) amplitude filter cavity, was proposed \cite{Corbitt2004-3}. Here we consider an improved version of this scheme, which allows to further reduce the quantum noise by exploiting the quantum entanglement between the optical fields at the filter cavity two ports.Comment: 10 pages, 7 figure

Hacking Smart Machines with Smarter Ones: How to Extract Meaningful Data from Machine Learning Classifiers

Machine Learning (ML) algorithms are used to train computers to perform a variety of complex tasks and improve with experience. Computers learn how to recognize patterns, make unintended decisions, or react to a dynamic environment. Certain trained machines may be more effective than others because they are based on more suitable ML algorithms or because they were trained through superior training sets. Although ML algorithms are known and publicly released, training sets may not be reasonably ascertainable and, indeed, may be guarded as trade secrets. While much research has been performed about the privacy of the elements of training sets, in this paper we focus our attention on ML classifiers and on the statistical information that can be unconsciously or maliciously revealed from them. We show that it is possible to infer unexpected but useful information from ML classifiers. In particular, we build a novel meta-classifier and train it to hack other classifiers, obtaining meaningful information about their training sets. This kind of information leakage can be exploited, for example, by a vendor to build more effective classifiers or to simply acquire trade secrets from a competitor's apparatus, potentially violating its intellectual property rights

Further insights on predictors of environmental tobacco smoke exposure during the pediatric age

Background: The smoking ban in public places has reduced Environmental Tobacco Smoke (ETS) exposure for non-smokers, but despite this, domestic environments still remain places at high risk of exposure, and, today, about 40% of children worldwide are exposed to ETS at home. The aims of the study are to investigate the contribution of several factors on ETS exposure among a group of Italian children and to evaluate the changes in smoking precautions adopted at home when the smoker is the mother, the father, or both parents, respectively. Methods: A cross-sectional study was performed on a sample of 519 Italian schoolchildren. Information was collected via a questionnaire. Results: 41.4% of the participants lived with at least one smoker. Almost half of the children exposed to ETS lived with one or more smokers who do not observe any home smoking ban. Lower maternal or paternal educational levels significantly increase the risk of ETS exposure at home and the “worst case” is represented by both parents who smoke. Conclusions: More effective preventive interventions are needed to protect children from ETS exposure. Some interventions should be specifically dedicated to smokers with a low educational level and to mothers that smoke

Comment on "The static evolution of the new Italian code of medical ethics"

The manuscript by Montanari Vergallo et al. appears primarily important because it resubmits the discussion on the relationshi between law and ethica norm in medical practice, as being responsible for promoting professional conduct or slowing it down and depriving it of its meaning
