It exists on the whole real line, and is uniformly continuous. We show that fractional moments can be expressed in terms of Riemann-Liouville integrals and derivatives of the fractional characteristic function. The fractional moments are of interest in particular for distributions whose integer moments do not exist. Some illustrative examples for particular distributions are also presented.}, language = {en} } @article{HortobagyiVetrovskyBalbimetal.2022, author = {Hortob{\´a}gyi, Tibor and Vetrovsky, Tomas and Balbim, Guilherme Moraes and Sorte Silva, Narlon Cassio Boa and Manca, Andrea and Deriu, Franca and Kolmos, Mia and Kruuse, Christina and Liu-Ambrose, Teresa and Radak, Zsolt and Vaczi, Mark and Johansson, Hanna and Rocha dos Santos, Paulo Cezar and Franzen, Erika and Granacher, Urs}, title = {The impact of aerobic and resistance training intensity on markers of neuroplasticity in health and disease}, series = {Ageing research reviews : ARR}, volume = {80}, journal = {Ageing research reviews : ARR}, publisher = {Elsevier}, address = {Clare}, issn = {1568-1637}, doi = {10.1016/j.arr.2022.101698}, pages = {18}, year = {2022}, abstract = {Objective: To determine the effects of low- vs. high-intensity aerobic and resistance training on motor and cognitive function, brain activation, brain structure, and neurochemical markers of neuroplasticity and the association thereof in healthy young and older adults and in patients with multiple sclerosis, Parkinson's disease, and stroke. Design: Systematic review and robust variance estimation meta-analysis with meta-regression. Data sources: Systematic search of MEDLINE, Web of Science, and CINAHL databases. Results: Fifty studies with 60 intervention arms and 2283 in-analyses participants were included. Due to the low number of studies, the three patient groups were combined and analyzed as a single group. Overall, low- (g=0.19, p = 0.024) and high-intensity exercise (g=0.40, p = 0.001) improved neuroplasticity. Exercise intensity scaled with neuroplasticity only in healthy young adults but not in healthy older adults or patient groups. Exercise-induced improvements in neuroplasticity were associated with changes in motor but not cognitive outcomes. Conclusion: Exercise intensity is an important variable to dose and individualize the exercise stimulus for healthy young individuals but not necessarily for healthy older adults and neurological patients. This conclusion warrants caution because studies are needed that directly compare the effects of low- vs. high-intensity exercise on neuroplasticity to determine if such changes are mechanistically and incrementally linked to improved cognition and motor function.}, language = {en} } @article{Hassler2022, author = {Haßler, Gerda}, title = {Meaning and Function}, series = {Concordia discors vs. discordia concors : researches into comparative literature, contrastive linguistics, translation and cross-cultural strategies}, volume = {16}, journal = {Concordia discors vs. discordia concors : researches into comparative literature, contrastive linguistics, translation and cross-cultural strategies}, number = {2}, publisher = {Ştefan cel Mare University Press}, address = {Suceava}, issn = {2065-4057}, pages = {17 -- 50}, year = {2022}, abstract = {The use of the word functional in the most diverse theories and approaches has contributed in no small measure to the confusion in linguistics today. This article does not claim to give an overview of the different directions of functionalism in linguistics. Rather, the aim is to present what Coseriu's view characterised as functional in his time and to what extent his theory outlined a path that still makes sense in functional-cognitive linguistics today. This will involve an examination of Coseriu's difficult-to-identify concept of function. Furthermore, the article will also show that functional thinking is relevant for current grammatography.}, language = {en} }
