A Dunning-Kruger-hatás vizsgálata vállalati környezetben
No full textA szakdolgozatom a Dunning-Kruger hatást dolgozza egy debreceni vállalat munkacsoportjaiba. A szakdolgozatom első részében maga a Dunning-Kruger hatást fejtem ki és azokhoz tartozó teszteket. A következő szakabaszban a vizsgált csoport által produlkált eredményeket számítom ki. Ezeket a számítások először Excel táblázatban majd pedig utána SPSS-ben dolgoztam fel. Végül prezentálom az eredményemet és azt is, hogy a Dunning-Kruger hatás megjelenik a dolgozóknál. A gyengébb teljesítményű dolgozók igenis hajlamosat túlbecsül a teszt eredményeiket. A jobban teljesített dolgozók szintén hajlamosak voltak a becslés elrontására, de ők a teljesítményüket alul becsülték.BSc/BAgazdaságinformatikaL

Photodynamic therapy of prostate cancer by means of 5-aminolevulinic acid-induced protoporphyrin IX - In vivo experiments on the dunning rat tumor model
No full textObjective: In order to expand the use of photodynamic therapy (PDT) in the treatment of prostate carcinoma (PCA), the aim of this study was to evaluate PDT by means of 5-aminolevulinic acid (5-ALA)-induced protoporphyrin IX ( PPIX) in an in vivo tumor model. Methods: The model used was the Dunning R3327 tumor. First of all, the pharmacokinetics and the localization of PPIX were obtained using fluorescence measurement techniques. Thereafter, PDT using 150 mg 5-ALA/kg b.w.i.v. was performed by homogenous irradiation of the photosensitized tumor (diode laser lambda = 633 nm). The tumors necrosis was determined histopathologically. Results: The kinetics of PPIX fluorescence revealed a maximum intensity in the tumor tissue within 3 and 4.5 h post-application of 5-ALA. At this time, specific PPIX fluorescence could be localized selectively in the tumor cells. The PDT-induced necrosis (n = 18) was determined to be 94 B 12% (range 60-100%), while the necrosis of the controls ( n = 12) differs significantly (p < 0.01), being less than 10%. Conclusion: These first in vivo results demonstrate the effective potential of 5-ALA-mediated PDT on PCA in an animal model. Copyright (C) 2004 S. Karger AG, Basel
Coherent atomic manipulation and cooling using composite optical pulse sequences
No full textThe laser cooling of atoms to ultracold temperatures has propelled many groundbreaking advances in fundamental research and precision measurement, through such applications as quantum simulators and interferometric sensors. Laser cooling remains, however, highly species-selective, and techniques for its application to molecules are still in their infancy.This thesis broadly concerns the development of laser cooling schemes, based on sequences of coherent optical pulses, which can in principle be applied to a wide range of species. We describe a cooling scheme, in which a velocity-selective impulse analogous to that in Doppler cooling is generated by a light-pulse Ramsey interferometer, and present a proof-of-concept demonstration of the scheme using ultracold rubidium-85 atoms as a test-bed. We realise an interferometer for the atoms, as they are in free-fall after release from a magneto-optical trap, by inducing stimulated Raman transitions between their ground hyperfine states. We provide a comprehensive characterisation of these Raman light-pulse interferometer optics, where particular attention is paid to light shift effects.Raman pulses, and indeed coherent operations in any quantum control system, unavoidably suffer from systematic errors in the control field intensity and frequency, and these lead to reductions in pulse fidelity and readout contrast. In parallel to the work on interferometric cooling in this thesis, we report our preliminary investigations into composite pulses, whereby 'naive' single pulses are replaced by sequences of rotations with tailored durations and phases, for improving pulse fidelity in the presence of inhomogeneities. We find that composite pulses can indeed be highly effective in our cold atom system, and propose that their application in such devices as interferometric sensors is a promising prospect

Disaster threat and the Dunning-Kruger effect
No full textDecision making is a cognitive process of selecting a course of action or belief amongmultiple alternative choices. However, pressures of time, circumstance or unappreciated wickedness can create a situation where an ostensibly illogical choice overtakes rational decision making. Sometimes, when evaluated by those considered experts, decisions made in disasters seem irrational, harmful, or iniquitous in nature. A cognitive bias known as the Dunning-Kruger effect posits that individuals who lack the necessary skills to make rational decisions can also lack the metacognitive ability to realize that their decision making is flawed. The Dunning-Kruger theory theorizes this can result in the individual exhibiting overconfidence to adequately address the threat. Essentially, the unskilled are unaware and overconfident. This thesis investigates the occurrence of the Dunning-Kruger effect in individual decision making during disasters. The author analyzed 12 indicators by coding interview transcripts of disaster survivors. This thesis includes two case studies: Hurricane Katrina, representing a natural disaster, and the World Trade Center attacks, exemplifying a human-caused disaster. In each case, 30 transcripts of survivors were reviewed, and Dunning-Kruger indicators were present in both case studies. How individuals process realized or perceived threat is important for homeland security policy makers. Future research should be conducted to better understand how Dunning-Kruger effects influence disaster decision making.Approved for public release; distribution is unlimited.Fire Marshal, City of Edina, Minnesotahttp://archive.org/details/disasterthreatnd109455161
