Cognitive Film Theory : An Insider’s Appraisal

Cet article évalue la contribution de l'approche cognitive aux études cinématographiques et indique les voies à emprunter pour que cette approche soit aussi efficace et utile que possible. L'auteur montre d'abord que les études « cognitivistes » du cinéma ne sont telles qu'au sens large du terme et qu'elles pourraient tout aussi bien être qualifiées d'« analytiques ». Il fait ensuite valoir que l'approche cognitive serait plus utile si elle était appliquée de façon plus générale, devenant alors davantage un engagement en faveur de la rationalité du discours et de la pensée humaine qu'un projet se tenant strictement dans les limites de la psychologie. Enfin, il démontre l'utilité de l'approche cognitive pour la compréhension du pouvoir psychologique du cinéma et de l'esthétique du film.This article appraises the contributions of what has been called cognitivism or the cognitive approach to film studies, and suggests the means by which the cognitive approach can become more central to film studies than it has been so far. The author first shows that much of what has been called "cognitivist" film studies is only cognitivist in a broad sense, and could just as well be called "analytic." He then argues that the cognitive approach would be most useful when it is thus broadly applied, becoming then more a commitment to the rationality of discourse and human thought than a narrow project within psychology. The article then goes on to appraise the utility of the cognitive approach in our understanding of the psychological power of film and film aesthetics

Digital afx: digital dressing and affective shifts in Sin City and 300

In Sin City (Robert Rodriguez, 2005) and 300 (Zack Snyder, 2006) extensive post-production work has created stylised colour palettes, manipulated areas of the image, and added or subtracted elements. Framing a discussion around the terms ‘affect’ and ‘emotion’, this paper argues that the digital technologies used in Sin City and 300 modify conventional interactions between representational and aesthetic dimensions. Brian Massumi suggests affective imagery can operate through two modes of engagement. One mode is embedded in a meaning system, linked to a speci?c emotion. The second is understood as an intensi?cation whereby a viewer reacts but that reaction is not yet gathered into an alignment with meaning. The term ‘digital afx’ is used to describe manipulations that produce imagery allowing these two modes of engagement to coexist. Digital afx are present when two competing aesthetic strategies remain equally visible within sequences of images. As a consequence the afx mingle with and shift the content of representation

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe

The growth of acute kidney injury: a rising tide or just closer attention to detail?

Acute kidney injury (AKI), previously termed acute renal failure, is associated with increased mortality, prolonged hospital stay, and accelerated chronic kidney disease (CKD). Over the past 2 decades, dramatic rises in the incidences of AKI have been reported, particularly within the United States. The question arises as to whether these changes reflect actual increases in disease incidence, or are potentially explained by the introduction of consensus definitions that rely on small standardized changes in serum creatinine, changes in coding and reimbursement, or increasingly available and more liberal use of dialysis. In this review, we explore the secular trends in AKI incidence in North America and Western Europe and its potential contributors
