MOJAVE. XIII. New 15GHz observations on 1994-2013

2017

We present 1625 new 15GHz (2cm) VLBA images of 295 jets associated with active galactic nuclei (AGNs) from the MOJAVE and 2cm VLBA surveys, spanning observations between 1994 August 31 and 2013 August 20. For 274 AGNs with at least 5 VLBA epochs, we have analyzed the kinematics of 961 individual bright features in their parsec-scale jets. A total of 122 of these jets have not been previously analyzed by the MOJAVE program. In the case of 451 jet features that had at least 10 epochs, we also examined their kinematics for possible accelerations. At least half of the well-sampled features have non-radial and/or accelerating trajectories, indicating that non-ballistic motion is common in AGN je…

Radio-optical scrutiny of compact AGN

2010

We study the correlations between the VLBA (Very Long Baseline Array) radio emission at 15GHz, extended emission at 151MHz, and optical nuclear emission at 5100{AA} for a complete sample of 135 compact jets. We use the partial Kendall's tau correlation analysis to check the link between radio properties of parsec-scale jets and optical nuclear luminosities of host active galactic nuclei (AGN).

Analiza anatomiczna drewna reliktowej sosny zwyczajnej z Sokolicy

2021

The work describes anatomical analysis of the wood from a relict Pinus sylvestris L. performed to determine its characteristics. Transverse ca. 20 μm thick sections were prepared with a core-microtome and observed in bright-field microscopy. Observations of tangential sections were performed in epi-fluorescence. The xylem of the relict pine showed many narrow growth rings. The occurrence of i.a. discontinuous tree rings, light rings and intraannual density fluctuations was stated. It can be expected that specific properties of the wood of the studied pine are the result of harsh growing conditions – limited water availability at the top of Sokolica. In addition, a wide range of factors affe…

Dentro il palazzo dell'arcivescovo. Un inventario palermitano del 1476

2019

Lo studio si propone di fare luce su alcuni aspetti legati alla vita dell’arcivescovado palermitano alla fine del XV secolo attraverso l’analisi dei beni mobili elencati in una fonte inedita che viene integralmente trascritta. Si tratta di un inventario compilato dal notaio Giacomo Randisi nel dicembre 1476, dopo la morte dell’arcivescovo Paolo Visconti, a evitare che i beni fossero sottratti alla Chiesa di Palermo o portati lontano dalla città: l'elenco degli oggetti esistenti nelle due sedi arcivescovili del Palazzo cittadino e in quello dello Scibene, consente di mettere a fuoco il contesto sociale, economico e culturale dell’arcivescovado palermitano e di gettare nuova luce su un monume…

Quantitative Runge Approximation and Inverse Problems

2017

In this short note we provide a quantitative version of the classical Runge approximation property for second order elliptic operators. This relies on quantitative unique continuation results and duality arguments. We show that these estimates are essentially optimal. As a model application we provide a new proof of the result from \cite{F07}, \cite{AK12} on stability for the Calder\'on problem with local data.

Difficult but Valuable! Learning in Student-centered Assessment Feedback Practices in Higher Education

2022

Aims: The aim of this study is to fill a gap in research on students' experiences of learning in student-centered assessment feedback practices. The article examines what students tell us about their learning in the context of student-centered feedback practices in higher education during online learning.
 Study Design: The study was conducted as a qualitative online survey among Finnish university students (N=35). The relationship between learning and assessment was explored in the context of formative and summative assessment practices during an online learning environment. The data was analysed using a discursive approach.
 Place and Duration of Study: The research was conducte…

OpenDigi toimintamallin käsikirja : opettajat oppimistaitojen ja digipedagogiikan kehittäjäyhteisöissä

2020

Yhteiskunnallisen muutoksen kiihtyessä on muuttuneisiin osaamistarpeisiin reagoitava myös koulutuksessa. Uudeksi kansalaistaidoksi ja ammatillisen osaamisen ytimeksi on nousemassa kyky uudistua ja sopeutua jat-kuvaan muutokseen. Suomalaisen koulutuksen laatu nojaa vahvasti akateemiseen opettajankoulutukseen. Yh-teiskunnallinen kehitys haastaa opettajankoulutusta ja kouluja tukemaan entistä vahvemmin ihmisten aktiivista roolia muutoksen tekijöinä ja siihen sopeutujina. Tutkintojen suorittamisen lisäksi koulutusjärjestelmän tulee antaa parempia valmiuksia aktiiviseen oppimiseen. Tämä edellyttää uudistumista koulutuksen kaikilla tasoilla. Koulutuksen muutos edellyttää oppilaitoksissa toimivien…

Realizacja zasady równości w zakresie dostępu do dóbr kultury narodowej

2021

Celem niniejszego tekstu jest udowodnienie, że art. 6 ust. 1 jest przepisem wskazującym na szczegółową dziedzinę, w której zastosowanie ma zasada równości wyrażona w treści art. 32 i 33 Konstytucji RP. Aby tego dowieźć, wyjaśniono, jak równość odnosi się do zakresu podmiotów uprawnionych do tego, aby im upowszechniać i udostępniać dobra kultury narodowej. Udowodnione zostało również, że odniesienie równości do upowszechniania i udostępniania dóbr kultury narodowej wymaga zastosowania uprzywilejowania wyrównawczego wynikającego z przesłanek faktycznych, a nie tylko prawnych. Przy okazji tak zakrojonych badań wykazane zostało również, że art. 6 ust. 1 jest także konkretyzacją art. 5 in fine o…

MODELLING AND SIMULATING RISKS IN THE TRAINING OF THE HUMAN RESOURCES BY APPLYING THE CHAOS THEORY

2012

The article approaches the modelling and simulation of risks in the training of the human resources, as well as the forecast of the degree of human resources training impacted by risks by applying the mathematical tools offered by the Chaos Theory and mathematical statistics. We will highlight that the level of knowledge, skills and abilities of the human resources from an organization are autocorrelated in time and they depend on the level of a previous moment of the training, as well as on the impact of the risk factors that can materialize in the process of the continuous training of human resources. The process of self-correlation and continuous training ensures the sustainable and qual…

Intentions of early retirement and continuing to work among middle-aged and older employees

2009

The purpose of this study is to investigate personal, health, work, and work-related psychological factors in association with employee intentions of early retirement and continuing to work after retirement in the form of bridge employment. In addition, the study aims to further our understanding of what motivates older employees by investigating age-related differences in employee reward preferences. The study draws upon several theoretical perspectives, including continuity theory, the life course perspective, theories on motivation, and the meaning of work for older employees. Survey data from three individual research projects are used in this study - age management studies consisting o…
