The absolute gravity measurements are an important tool for reliable monitoring geodynamic phenomena. Based on the experience with the absolute gravimeter FG5#215 (gravimeter of the Center for Earth Dynamics Research), the accuracy of FG5 absolute gravimeters is presented in this study. The instrumental reproducibility of this meter is characterized by the value of 0.7 μGal. Discussed are important environmental effects on gravity measurements, such as atmospheric and hydrological effects, understanding of which is necessary for correct and reliable interpretation of the repeated absolute gravity measurements in geodynamics., Vojtech Pálinkáš, Jakub Kostelecký and Jaroslav Šimek., and Obsahuje bibliografii
Autor porovnáva koncepciu merania, ktorá sa uplatňuje v psychológii, s koncepciou merania v prírodných vedách, reprezentovanou heslami medzinárodného metrologického slovníka. Odmieta chápanie merania ako priraďovania čísel objektom a tzv. nominálnu škálu. Meranie pokladá za užší pojem než kvantifikácia. Psychologická kvantifikácia nie je meraním, ale pravdepodobnostným odhadom úrovne latentnej premennej, ktorej existenciu iba predpokladáme (na rozdiel od reálne existujúcich veličín v prírodných vedách). and The author compares the concept of measurement as applied in psychology with the concept of measurement in natural sciences represented by entries in the international dictionary of metrology. He rejects the concept of measurement as assigning numbers to objects and so-called “nominal scale”. The author considers the measurement a less broad concept then quantification. Psychological quantification is not a measurement but a probabilistic assessment of a latent variable level that we only presume (contrary to really existing quantities in natural sciences).
