This paper describes the application of eight statistical and machine-learning methods to derive computer models for predicting mortality of hospital patients with pneumonia from their findings at initial presentation. The eight models were each constructed based on 9847 patient cases and they were each evaluated on 4352 additional cases. The primary evaluation metric was the error in predicted survival as a function of the fraction of patients predicted to survive. This metric is useful in assessing a model’s potential to assist (...) a clinician in deciding whether to treat a given patient in the hospital or at home. We examined the error rates of the models when predicting that a given fraction of patients will survive. We examined survival fractions between 0.1 and 0.6. Over this range, each model’s predictive error rate was within 1% of the error rate of every other model. When predicting that approximately 30°K of the patients will survive, all the models have an error rate of less than 1.5%. The models are distinguished more by the number of variables and parameters that they contain than by their error rates; these differences suggest which models may be the most amenable to future implementation as paper-based guidelines.

Psychologists from nineteen countries in Asia and Oceania report on the expansion of western psychology in the region at both the academic and the professional levels. With its own network of associations, conferences, and journals, the comminity of psychologists in the East has braved new frontiers for the discipline.

In this fascinating collection of essays, noted critic Geoffrey Hartman raises the essential question of where we can find the real or authentic in today's world, and how this affects the way we understand our human predicament. Hartman explores such issues as the fantasy of total information and perfect communication encouraged by the internet, the biographical excesses of tell-all talk shows that serve to shore up a personal sense of unreality, the tendency to motivate violence in the name of (...) some moral or spiritual necessity, and the increased difficulty of distinguishing between fakery and truth in confessional and testimonial writing. Underlying the entire book is the crucial issue of how the trauma of the Holocaust and other genocidal acts, brought home to us almost daily by the media, is shaping our quest for agency, identity and meaning. Against what he describes as a contempt for the aesthetic in the face of social suffering, Hartman produces a defense of art that helps to recast these questions. His idea is that the form of contemplation produced by the aesthetic, and particularly by poetry, resists both the fantasy of data delivering up their own final meaning and of ideology as a shortcut seeking to deliver us from literature and other deeply reflective and sometimes vulnerable--because self-critical--modes of expression.

In this extended prose poem—a text that reads as much as a work of art as important scholarship—Kurt H. Wolff has created a work of phenomenology that goes far beyond the typical methods of empirical social science to embrace field work as an extraordinary openness to being. Including personal letters to Wolff from Hannah Arendt and Hermann Bloch, the book portrays a fertile mind's reckoning with pre-phenomenal being in a way that dances between the realms of intellectual consideration and the (...) surrender of will to the intoxication of lived experience.

"Kevin Hart and Geoffrey H. Hartman bring together essays by prominent scholars from a range of disciplines to focus on Blanchot's diverse concerns: literature, art, community, politics, ethics, spirituality, and the Holocaust."--Jacket.

A novel social interaction is a dynamic process, in which participants adapt to, react to and engage with their social partners. To facilitate such interactions, people gather information relating to the social context and structure of the situation. The current study aimed to deepen the understanding of the psychological determinants of behavior in a novel social interaction. Three social robots and the participant interacted non-verbally according to a pre-programmed “relationship matrix” that dictated who favored whom. Participants' gaze was tracked during (...) the interaction and, using Bayesian inference models, resulted in a measure of participants' social information-gathering behaviors. Our results reveal the dynamics in a novel environment, wherein information-gathering behavior is initially predicted by psychological inflexibility and then, toward the end of the interaction, predicted by curiosity. These results highlight the utility of using social robots in behavioral experiments. (shrink)

Canadian capitalism has entered a period of intensified volatility. Rooted in persistent profitability problems, it is facing several challenges, including economic stagnation, a household-debt driven real-estate and construction boom, and an increasingly fragile financial system. Drawing on a classical Marxist framework of capitalist crisis, this article explores the dynamics of instability in Canada and the response of the capitalist state, which centres on increased efforts to export oil and gas to China, thereby deepening conflict with Indigenous land defenders, and a (...) redoubling of the assault on workers to increase the rate of exploitation.

The statements and arguments based on experimental evidence used to support the claim that the 3d sub-level is below the 4s sub-level in scandium are examined. The flaw in all the arguments is that they assume the order in which the 3d and 4s sub-levels arrange remains the same in both the neutral atom and in its ions. Analysis of the ground and excited states of atomic spectra shows that as the number of electrons relative to the nuclear charge increases, (...) the 3d level moves higher in energy relative to the 4s level. It is perfectly possible that in a neutral scandium atom the 3d sub-level is above the 4s sub-level and that when it ionizes the energy levels simultaneously rearrange during the process. (shrink)

Using data from American emergency call centers, this article focuses on the coordination, and mutual relevance, of participants’ effort to manage two forms of unit completion – sequence closing and concluding the occasion in which the project was pursued. In doing so, we specify the import of sequence organization as one method for conducting, organizing, and resolving interactional projects participants may be said to pursue, and describe a range of possible relations between project completion and occasion closure and the locations (...) from which problems come to be introduced as parties move to resolve projects and close calls. As we show, sequence and occasion closings produced in the service of projects are fateful: they inexorably demand that the participants arrive at some alignment – or make visible their failure to do so – regarding the projects pursued in it, the status of those projects, and thus who, as a consequence, the parties are for another, that is, their ‘identities’. For strangers and familiars both, the management of projects and the manner in which closing is achieved matters. (shrink)
