He develops a novel framework for information refinement, which integrates the event, organisational, societal, and technological perspectives of crises. Therefore, he reviews the state of the art on crisis informatics and empirically examines the use, potentials and barriers of both social media and mobile apps. Based on these insights, he designs and evaluates ICT concepts and artifacts with the aim to overcome the issues of information overload and quality in large-scale crises, concluding with practical and theoretical implications for technology adaptation and design. About the author: Marc-André Kaufhold is a postdoc at the Chair of Science and Technology for Peace and Security (PEASEC) in the Department of Computer Science at the Technical University of Darmstadt. His research focuses on the user-centred design and evaluation of mobile apps and social media technologies in the context of crisis and security research. 606 $aCrisis management$xInformation technology 606 $aOnline social networks 606 $aGestió de la crisi$2thub 606 $aTecnologia de la informació$2thub 606 $aComunitats virtuals$2thub 608 $aLlibres electrònics$2thub 615 0$aCrisis management$xInformation technology. 615 0$aOnline social networks. 615 7$aGestió de la crisi 615 7$aTecnologia de la informació 615 7$aComunitats virtuals 676 $a302.30285 700 $aKaufhold$b Marc-Andre?$0963824 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910483108703321 996 $aInformation Refinement Technologies for Crisis Informatics$92185776 997 $aUNINA LEADER 03963nam 2200529 450 001 9910810570003321 005 20231110233703.0 010 $a2-7598-2518-3 024 7 $a10.1051/978-2-7598-2518-9 035 $a(CKB)4100000011788883 035 $a(DE-B1597)586408 035 $a(DE-B1597)9782759825189 035 $a(MiAaPQ)EBC6510170 035 $a(Au-PeEL)EBL6510170 035 $a(OCoLC)1241444825 035 $a(MiAaPQ)EBC6810264 035 $a(Au-PeEL)EBL6810264 035 $a(PPN)254806597 035 $a(EXLCZ)994100000011788883 100 $a20220812d2021 uy 0 101 0 $aeng 135 $aur||||||||||| 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 10$aMeasuring the soul $epsychophysics for non-psychophysicists /$fCarlo Aleci 210 1$aLes Ulis :$cEDP Sciences,$d[2021] 210 4$d©2021 215 $a1 online resource (216 p.) 225 0 $aCurrent Natural Sciences 311 $a2-7598-2517-5 327 $tFrontmatter -- $tContents -- $tForeword -- $tIntroduction -- $tChapter 1 Adequate and Inadequate Stimuli -- $tChapter 2 The Threshold -- $tChapter 3 The Psychometric Function -- $tChapter 4 Detection and Discrimination Threshold -- $tChapter 5 Response Models -- $tChapter 6 False-Negative and False-Positive Errors (Lapse and Guess Rate) -- $tChapter 7 Psychophysical Procedures -- $tChapter 8 Adaptive Psychophysical Procedures -- $tChapter 9 Nonparametric Adaptive Psychophysical Procedures -- $tChapter 10 Parametric Adaptive Psychophysical Procedures -- $tChapter 11 Adaptive Psychophysical Procedures for the Estimate of the Slope -- $tChapter 12 Multidimensional Adaptive Testing -- $tChapter 13 What Makes a Psychophysical Technique a Good Psychophysical Technique? -- $tChapter 14 What is the Best Psychophysical Technique? -- $tChapter 15 Introduction to the Signal Detection Theory (SDT) -- $tChapter 16 Suprathreshold Psychophysics -- $tChapter 17 Brief Outline of Comparative Psychophysics -- $tAfterword The Inverse Problem of Perception -- $tAppendix I Logistic and Weibull Distribution -- $tAppendix II The Maximum Likelihood Estimation -- $tAppendix III Probit Analysis -- $tAppendix IV About Bayes? Theorem and Bayesian Statistics -- $tReferences -- $tIndex 330 $aEven in the age of Internet, when information and knowledge are just a click away, few probably know what is psychophysics and what is it for. Psychophysics can be romantically defined as the science that measures the soul, namely the sensory soul. Psychophysics estimates the sensibility and looks for the threshold, that ephemeral limit between the sensed and the not sensed, the perceived and the not perceived, the seen and the not seen. It is a challenging task, since this limit is like a butterfly twirling over a flowery meadow, and psychophysics is the tool aimed at measuring as exactly as possible the height of its flight. At the boundary between experimental psychology and sensory neuroscience, psychophysics is not confined within a theoretical framework, but has great importance also in the clinical setting: audiologists, ophthalmologists, optometrists, orthoptists as well as neuropsychiatrists make use of psychophysics in many of their diagnostic protocols. This book aims at describing the principles of this discipline in a simple yet rigorous form, so as to make psychophysics understandable to the broad audience of non-psychophysicists. And, why not, even to reveal its hidden charm. 410 0$aCurrent Natural Sciences 606 $aPsychophysics 606 $aPsychophysics$xMathematical models 615 0$aPsychophysics. 615 0$aPsychophysics$xMathematical models. 676 $a152.1 700 $aAleci$b Carlo$0479083 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910810570003321 996 $aMeasuring the soul$93926907 997 $aUNINA
