Assouad Type Dimensions in Geometric Analysis

2021

We consider applications of the dual pair of the (upper) Assouad dimension and the lower (Assouad) dimension in analysis. We relate these notions to other dimensional conditions such as a Hausdorff content density condition and an integrability condition for the distance function. The latter condition leads to a characterization of the Muckenhoupt Ap properties of distance functions in terms of the (upper) Assouad dimension. It is also possible to give natural formulations for the validity of Hardy–Sobolev inequalities using these dual Assouad dimensions, and this helps to understand the previously observed dual nature of certain cases of these inequalities. peerReviewed

On some partial data Calderón type problems with mixed boundary conditions

2021

In this article we consider the simultaneous recovery of bulk and boundary potentials in (degenerate) elliptic equations modelling (degenerate) conducting media with inaccessible boundaries. This connects local and nonlocal Calderón type problems. We prove two main results on these type of problems: On the one hand, we derive simultaneous bulk and boundary Runge approximation results. Building on these, we deduce uniqueness for localized bulk and boundary potentials. On the other hand, we construct a family of CGO solutions associated with the corresponding equations. These allow us to deduce uniqueness results for arbitrary bounded, not necessarily localized bulk and boundary potentials. T…

Wspólnota jako wartość i dialog o wartościach : o dobru i złu w kontekście relacji ludzkich w wybranych tekstach Józefa Tischnera

2018

Spór na gruncie filozofii społecznej i politycznej o rozumienie wspólnoty głównie opiera się o trzy klasyczne stanowiska: indywidualizm, kolektywizm i wizja personalistyczna. Wydaje się, że określenie relacji między osobą a wspólnotą są zależne od tego, jakie jest źródło antropologii i etyki. W artykule przedstawia się wizję wspólnoty Józefa Tischnera. Przedstawił koncepcje relacji między osobą a wspólnotą w ujęciu filozofii dialogu i filozofii spotkania. Kategoria wartości i dialogu o wartościach jest jednym z kluczowych elementów tischnerowskiej filozofii. Stąd słusznym wydaje się ukazanie poglądów na temat wspólnoty w kontekście aksjologicznym. Pytania na scenie dramatu to pytania o dobr…

Między indywidualizmem a kolektywizmem - o filozofii wspólnoty Jeana Vaniera. Wybrane aspekty i problemy antropologiczno-etyczne

2018

Spór na gruncie filozofii społecznej i politycznej o rozumienie wspólnoty głównie opiera się o trzy klasyczne stanowiska: indywidualizm, kolektywizm i wizja personalistyczna. Wydaje się, że określenie relacji między osobą a wspólnotą są zależne od tego, jakie jest źródło antropologii i etyki. W artykule przedstawia się wizję wspólnoty obecnie mieszkającego we Francji filozofa i teologa Jeana Vaniera. W jego osobie zauważa się łączenie wiedzy z doświadczeniem, teorię z praktyką. Owocem tych „łączeń” jest istniejąca do dzisiaj wspólnota L 'Arche.

Merging Features from Green's Functions and Time Dependent Density Functional Theory: A Route to the Description of Correlated Materials out of Equil…

2016

We propose a description of nonequilibrium systems via a simple protocol that combines exchange-correlation potentials from density functional theory with self-energies of many-body perturbation theory. The approach, aimed to avoid double counting of interactions, is tested against exact results in Hubbard-type systems, with respect to interaction strength, perturbation speed and inhomogeneity, and system dimensionality and size. In many regimes, we find significant improvement over adiabatic time dependent density functional theory or second Born nonequilibrium Green's function approximations. We briefly discuss the reasons for the residual discrepancies, and directions for future work.

Heart Rate Variability Monitoring During Strength and High-Intensity Interval Training Overload Microcycles

2019

Objective: In two independent study arms, we determine the effects of strength training (ST) and high-intensity interval training (HIIT) overload on cardiac autonomic modulation by measuring heart rate (HR) and vagal heart rate variability (HRV). Methods: In the study, 37 well-trained athletes (ST: 7 female, 12 male; HIIT: 9 female, 9 male) were subjected to orthostatic tests (HR and HRV recordings) each day during a 4-day baseline period, a 6-day overload microcycle, and a 4-day recovery period. Discipline-specific performance was assessed before and 1 and 4 days after training. Results: Following ST overload, supine HR, and vagal HRV (Ln RMSSD) were clearly increased and decreased (small …

Promotions and Earnings – Gender or Merit? Evidence from Longitudinal Personnel Data

2017

This study examines the determinants of promotions, performance evaluations and earnings using unique longitudinal data from the personnel records of a large university. The study focuses on the role of gender in remuneration using, first, information on the complexity ratings of job tasks to define promotions on job ladders and, second, information on objective individual productivity. The study finds that individual research productivity was an important determinant of promotions and earnings. The results indicate that gender has no effect on the probability of being promoted, conditional on productivity, nor does it play a role in the performance evaluation of employees. Furthermore, the…

Labour market reforms, institutions, and the quality of employment : should we all follow German Hartz model in reforming labour markets?

2015

Underemployment and aging population are major threats for several European economies. This study asks, whether partial labour market reforms, similar to German Hartz reforms, were good choices for other European countries, especially in terms of the quality of employment. Labour market liberalisation effects are assessed from macro-perspective on 25 OECD countries with fixed-effects panel data analysis. The effects for full-time, part-time, temporary, and low-wage employment are analysed separately for both genders, and also on young adults. The results find out strongly a gendered nature of labour market deregulation effects, which give support for dual labour market theory. There appears…
