Naming Our Concerns about Neuroscience: A Review of Bennett and Hacker's Philosophical Foundations of Neuroscience

Bennett and Hacker use conceptual analysis to appraise the theoretical language of modern cognitive neuroscientists, and conclude that neuroscientific theory is largely dualistic despite the fact that neuroscientists equate mind with the operations of the brain. The central error of cognitive neuroscientists is to commit the mereological fallacy, the tendency to ascribe to the brain psychological concepts that only make sense when ascribed to whole animals. The authors review how the mereological fallacy is committed in theories of memory, perception, thinking, imagery, belief, consciousness, and other psychological processes studied by neuroscientists, and the consequences that fallacious reasoning have for our understanding of how the brain participates in cognition and behavior. Several behavior-analytic concepts may themselves be nonsense based on thorough conceptual analyses in which the criteria for sense and nonsense are found in the ways the concepts are used in ordinary language. Nevertheless, the authors' nondualistic approach and their consistent focus on behavioral criteria for the application of psychological concepts make Philosophical Foundations of Neuroscience an important contribution to cognitive neuroscience

Stalker, de Andrei Tarkovski, e a mise-en-scène como forma de experiência

The present research aims to think about the film Stalker, by the Russian director Andrei Tarkovski, from the concept of experience of the philosopher Walter Benjamin. The study was based on the analysis of the film's mise-en-scène, in order to think of it as a power to break the automatism and to perceive the images as a way of "feeling" life - a concept present in the reflection text of Viktor Chklovsky Art as procedureSubmitted by José Ricardo da Rocha Cacciari ([email protected]) on 2017-10-27T22:55:44Z No. of bitstreams: 2 license_rdf: 811 bytes, checksum: e39d27027a6cc9cb039ad269a5db8e34 (MD5) Stalker, de Andrei Tarkovski, e a Mise-en-scène cono forma de experiência.pdf: 2448360 bytes, checksum: 90f377f87116b0361920f7cd899a0cf2 (MD5)Approved for entry into archive by Karina Ramos Wagner ([email protected]) on 2017-11-06T10:46:31Z (GMT) No. of bitstreams: 2 license_rdf: 811 bytes, checksum: e39d27027a6cc9cb039ad269a5db8e34 (MD5) Stalker, de Andrei Tarkovski, e a Mise-en-scène cono forma de experiência.pdf: 2448360 bytes, checksum: 90f377f87116b0361920f7cd899a0cf2 (MD5)Made available in DSpace on 2017-11-06T10:46:31Z (GMT).

In-situ calibration and validation of CryoSat-2 observations over Arctic first year sea ice north of Svalbard

Large areas of the Arctic Ocean are covered with sea ice, the extent, thickness, concentration and properties of which change seasonally, interannually and on longer time scales. The Arctic Ocean is often difficult to access, making satellite remote sensing the only means to obtain information about the sea ice on a pan-Arctic scale. In order to improve the processing and interpretation of satellite data and imagery, in-situ calibration and validation are necessary. In spring 2011, measurements on first year sea ice north of Svalbard were performed during two scientific cruises with the ships KV “Svalbard” and RV “Lance” as a part of the CryoVEx 2011 project. During these cruises, detailed measurements of snow and ice thickness, freeboard, and snow density were performed on ice stations and from a helicopter. The data collected contributes to the calibration and validation of the SIRAL sensor data from the CryoSat-2 radar altimeter satellite, which measures the freeboard of sea ice for estimating its thickness. In snow pits, the stratigraphy of the snow pack was recorded. The collected data are currently being integrated with satellite data, airborne observations from helicopter that measured ice thickness using an electromagnetic induction sounder (EM-bird) and conducted aerial photography, and a Twin-Otter aircraft carrying the ESA Airborne Synthetic Aperture and Interferometric Radar Altimeter System (ASIRAS) system, the airborne radar altimeter designed to simulate the SIRAL radar on board the satellite, as well as a laser scanner. The first analysis of airborne and in- situ data indicates that the ASIRAS radar altimeter used in this experiment did not fully penetrate the snow layer on top of the sea ice. The regional sea ice characteristics for the research area are described using SAR products, obtained from the Envisat and Radarsat-2 satellites, in order to improve the interpretation and conclusions of the CryoSat-2 calibration and validation
