Novel Multimodal Feedback Techniques for In-Car Mid-Air Gesture Interaction

This paper presents an investigation into the effects of different feedback modalities on mid-air gesture interaction for infotainment systems in cars. Car crashes and near-crash events are most commonly caused by driver distraction. Mid-air interaction is a way of reducing driver distraction by reducing visual demand from infotainment. Despite a range of available modalities, feedback in mid-air gesture systems is generally provided through visual displays. We conducted a simulated driving study to investigate how different types of multimodal feedback can support in-air gestures. The effects of different feedback modalities on eye gaze behaviour, and the driving and gesturing tasks are considered. We found that feedback modality influenced gesturing behaviour. However, drivers corrected falsely executed gestures more often in non-visual conditions. Our findings show that non-visual feedback can reduce visual distraction significantl

Obscure Certificates Could Cut Down Recidivism

When you’re convicted of a crime, your punishment doesn’t end with prison. Your life is harder until you die. New Yorkers with criminal histories can get these Certificates that make life a little less hard. They’re a kind of a diploma of rehabilitation. The standards for getting them aren’t that high. Most people who’ve been convicted of a crime are eligible, in theory. But hardly anybody gets them. This article is about the ignorance and legal contradictions that have made them so obscure

A metallographic study of certain sintered zirconium base alloys.

Following a literature survey and a number of exploratory experiments, mixtures of zirconium and chromium powders containing up to 18% by weight of chromium were cold pressed and sintered in vacuo at temperatures in the range 900°C -1100°C. for times up to 16 hours. The densities and hardnesses of the sintered alloys were determined and the resultant micro-structures were examined under the optical microscope. The density and hardness results were subjected to an analysis of variance to establish the significances and validities of the observed trends. It was found that both density and hardness increased with increasing temperature and time of sintering and with increasing chromium content, the rates of increase were less in the upper temperature ranges, and sintering temperature was a more significant variable than either of the other two. In no case were theoretical maximum densities obtained, and anomalous density decrements were observed associated with particular combinations of sintering temperature and time. Microscopic examinations of the alloys showed that in no case were equilibrium conditions reached, although the alpha-zirconium/ZrCr[2] eutectoid and some massive ZrCr[2] were formed, complete solution of the free chromium particles in the zirconium matrix was not obtained. Porosity, of two types, was seen. The normal sintering porosity showed a decrease in pore number and an increase in pore size with increased sintering. At the higher temperatures and longer times of sintering, other pores were seen associated with the free/free chromium/zirconium matrix interfaces. These pores were attributed to differential diffusion effects across the interfaces and account for the anomalous density effects. Certain phenomena associated with abnormal sintering conditions were also detected and examined. A number of conclusions were drawn on all aspects of the work and possible further work was outlined

An adolescent girl with signs and symptoms of anaphylaxis and negative immunologic workup: a case report.

BackgroundThe increasing incidence of allergies and allergic reactions among children and adults has become a major public health concern. The etiology of allergic reactions can often be confirmed based on a detailed history and supportive testing. However, there are cases where the underlying factors are more complex and difficult to identify.Case presentationHere we present the case report of a 14-year-old Caucasian  girl with weight loss and a 3-year history of reported angioedema culminating in five intensive care unit admissions over the course of 2.5 months. Her initial clinical presentation included hypotension, dyspnea, and reported facial edema, but allergy and immunological workup were negative. A psychiatric workup identified an eating disorder with food restriction, comorbid major depression, obsessive compulsive disorder, and posttraumatic stress disorder. A close collaboration between Adolescent Medicine, Allergy and Immunology, and Psychiatry helped disentangle medical from psychiatric problems, including fluoxetine medication effects, as well as develop a treatment plan that was acceptable to the family. The angioedema was ultimately diagnosed as factitious disorder.ConclusionsThis patient's treatment highlights the importance of a multidisciplinary team approach, a multifactorial etiology that needed to be addressed by multiple specialists, and the importance of long-term treatment and support

Timing of poverty in childhood and adolescent health: Evidence from the US and UK

Childhood poverty is associated with poorer adolescent health and health behaviours, but the importance of the timing of poverty remains unclear. There may be critical or sensitive periods in early life or early adolescence, or poverty may have cumulative effects throughout childhood. Understanding when poverty is most important can support efficient timing of interventions to raise family income or buffer against the effects of low income, but answers may vary across social contexts. The US and the UK are a useful comparison with similar liberal approaches to cash transfers, but very different approaches to healthcare provision. Utilising data from large population studies in the US (n = 9408; born 1979–1996) and UK (n = 1204; born 1991–1997), this study employs a structured life course approach to compare competing hypotheses about the importance of the timing or pattern of childhood exposure to poverty in predicting adolescent health limitations, symptoms of psychiatric distress, and smoking at age 16 (age 15/16 in US). Household income histories identified experience of poverty (measured as <60% of the national median equivalised income for a given year) in early life (ages 0–5), mid-childhood (ages 6–10) and early adolescence (ages 11–15). The Bayesian Information Criterion (BIC) compared fit across models with variables representing different life course patterns of exposure to poverty. Adolescent distress was not associated with poverty in either country. In both countries, however, variables representing cumulative or persistent experiences of poverty exhibited optimal fit of all poverty exposure variables in predicting adolescent smoking and health limitations. There was also evidence of an early life sensitive period for smoking in the US. Poverty was more persistent in the US, but associations between poverty and outcomes were consistent across countries. Although poverty can have cumulative effects on health and behaviour, early interventions may offer the best long-term protection

Dynamics after a sweep through a quantum critical point

The coherent quantum evolution of a one-dimensional many-particle system after sweeping the Hamiltonian through a critical point is studied using a generalized quantum Ising model containing both integrable and non-integrable regimes. It is known from previous work that universal power laws appear in such quantities as the mean number of excitations created by the sweep. Several other phenomena are found that are not reflected by such averages: there are two scaling regimes of the entanglement entropy and a relaxation that is power-law rather than exponential. The final state of evolution after the quench is not well characterized by any effective temperature, and the Loschmidt echo converges algebraically to a constant for long times, with cusplike singularities in the integrable case that are dynamically broadened by nonintegrable perturbations.Comment: 4 pages, 4 figure

TWO POLITICIZATIONS OF U.S. ANTITRUST LAW

Critics have accused the Trump Department of Justice (DOJ) and Trump-appointee-chaired Federal Trade Commission (FTC) of populism, deviating from the more technocratic standards that governed agency interventions during the Bush and Obama eras. The broad brush of politicization has been applied to the administration\u27s handling of a wide variety of topics, ranging from marijuana and media mergers, to landmark lawsuits against Google and Facebook. But a more discerning eye is necessary here. The concept of the political has both authoritarian and democratic registers. The federal Google and Facebook antitrust cases reflected the democratization of high technology antitrust. Meanwhile, troublingly authoritarian tendencies (including a targeting of firms that seemed highly unlikely absent an effort to punish enemies and reward friends of the regime) characterized marijuana and some key media merger policy. Politicization is a complex and multifaceted feature of competition law enforcement. The challenge for antitrust is not to eradicate politics tout court. Rather, as the law and political economy movement teaches, it is to channel legitimate demands to restructure commercial life in ways that reflect and reconcile public values in a pluralistic democracy, harmonizing the interests of labor, consumers, and capital

Impact of imperfect test sensitivity on determining risk factors : the case of bovine tuberculosis

Background Imperfect diagnostic testing reduces the power to detect significant predictors in classical cross-sectional studies. Assuming that the misclassification in diagnosis is random this can be dealt with by increasing the sample size of a study. However, the effects of imperfect tests in longitudinal data analyses are not as straightforward to anticipate, especially if the outcome of the test influences behaviour. The aim of this paper is to investigate the impact of imperfect test sensitivity on the determination of predictor variables in a longitudinal study. Methodology/Principal Findings To deal with imperfect test sensitivity affecting the response variable, we transformed the observed response variable into a set of possible temporal patterns of true disease status, whose prior probability was a function of the test sensitivity. We fitted a Bayesian discrete time survival model using an MCMC algorithm that treats the true response patterns as unknown parameters in the model. We applied our approach to epidemiological data of bovine tuberculosis outbreaks in England and investigated the effect of reduced test sensitivity in the determination of risk factors for the disease. We found that reduced test sensitivity led to changes to the collection of risk factors associated with the probability of an outbreak that were chosen in the ‘best’ model and to an increase in the uncertainty surrounding the parameter estimates for a model with a fixed set of risk factors that were associated with the response variable. Conclusions/Significance We propose a novel algorithm to fit discrete survival models for longitudinal data where values of the response variable are uncertain. When analysing longitudinal data, uncertainty surrounding the response variable will affect the significance of the predictors and should therefore be accounted for either at the design stage by increasing the sample size or at the post analysis stage by conducting appropriate sensitivity analyses
