Czy religia utrwala moralną niedojrzałość jednostek ludzkich czy sprzyja rozwojowi ich moralnej dojrzałości?
2022
Jako ludzie doświadczamy swojej skończoności kruchości i bezsilności. Otaczający nas świat jest nietrwały, niestabilny, ulega destrukcji, mamy w nim do czynienie z niepewnością, przemijaniem, chorobami, starością i śmiercią. Religia dostarcza systemu orientacji i oddania, który w sposób całościowy określa porządek świata i miejsce człowieka w nim, wprowadza ład w życie, daje oparcie, nadaje sens ludzkiemu istnieniu, oswaja to, co niepewne, dodaje otuchy, pozwala okiełznać lęk. To dostarczanie systemu orientacji i czci może wzmacniać pierwotne tendencje natury ludzkiej, wzmacniać trybalizm i etnocentryzm. Dzieje się tak, gdy religia spełnia głównie rolę spoiwa dla wspólnoty, a jednostka prze…

Political Patronage in a Small Italian Local Government: An Outcome-Based DPM Approach on Fiduciary Practices
Corruption is “the abuse of public office for personal gain” (World Bank, 1997: 8). Although this definition captures a broad notion of corrupt behaviour, many forms of corruption actually occur in small municipalities each reflecting context-specific features and dynamics. Their impacts are rather evident, but their cause-effects relationships are not always clear, so that tangled issues may ineluctably arise without an apparent explanation. As such, a systemic focus is needed in order to gain an insightful understanding of particular configurations of malfeasance at local level in the attempt to hinder them in the future. The aim of this research project is to explore the dynamic relation…
X-ray flare modeling in the single giant HR 9024
2005
We analyze a Chandra-HETGS observation of the single G-type giant HR 9024. The high flux allows us to examine spectral line and continuum diagnostics at high temporal resolution, to derive plasma parameters (thermal distribution, abundances, temperature, ...). A time-dependent 1D hydrodynamic loop model with semi-length 10$^{12}$cm ($\sim R_{\star}$), and impulsive footpoint heating triggering the flare, satisfactorily reproduces the observed evolution of temperature and emission measure, derived from the analysis of the strong continuum emission. The observed characteristics of the flare appear to be common features in very large flares in active stars (also pre-main sequence stars), possi…

X-ray Emission in protostellar jets
2005
Prompted by the recent detection of X-ray emission from Herbig-Haro objects, we studied the interaction between a supersonic jet originating from a young stellar object and the ambient medium; our aim is to investigate the mechanisms causing the X-ray emission. Our model takes into account the radiative losses from optically in plasmas and Spitzer's thermal conduction including saturation effects. We explored the parameter space defined by the density contrast between the ambient medium and the jet and by the Mach number, to infer the configurations which can give rise to X-ray emission. From the models, we derived the X-ray emission as it would be observed with Chandra/ACIS-I and XMM-Newto…
