OPEN Repository

Welcome to OPEN - the Repository of Open Scientific Publications, run by the Interdisciplinary Centre for Mathematical and Computational Modelling, University of Warsaw, previously operating as the CeON Repository. The Repository enables Polish researchers from all fields to openly share their articles, books, conference materials, reports, doctoral theses, and other scientific texts.

Publications in the Repository are indexed by the most important search engines and aggregators and downloaded by users worldwide. We invite you to create an account, deposit your publications, and use the resources of the Repository.

Finansowanie szkoleń w jednostkach samorządu terytorialnego. Analiza budżetowa
(Uczelnia Jana Wyżykowskiego, Wydawnictwo Naukowe FNCE, 2023) Czopek, Miłosz; Ślebioda, Magdalena; Uczelnia Jana Wyżykowskiego w Polkowicach
Pracownicy są najważniejszym zasobem jednostek samorządu terytorialnego. Ich codzienna praca decyduje o postrzeganiu jakości zarządzania jednostkami przez lokalne społeczności. Oznacza to, że szkolenia mające na celu podnoszenie wiedzy, umiejętności i kompetencji odgrywają kluczową rolę w efektywnej realizacji różnorodnych zadań własnych i pozwalają podołać nowym wyzwaniom, z którymi jest konfrontowana administracja samorządowa. Analiza potrzeb szkoleniowych jest ważnym elementem procesu rozwoju kadr i oprócz dostarczania istotnych informacji dotyczących luki kompetencyjnej, pozwala również właściwie oszacować wysokość środków publicznych, które należy zabezpieczyć w budżecie jednostki. Artykuł prezentuje własne wyniki analizy budżetów jednostek dolnośląskiego samorządu terytorialnego, dotyczącej wysokości zaplanowanych i wykorzystanych środków na szkolenia. Okres przeprowadzonych badań objął lata 2018–2021. Opracowanie ukazuje również wnioski, sformułowane na podstawie przeprowadzonych badań.
Polish Teachers’ Opinions on the Distance Learning of Students with Autism Spectrum Disorder
(SPED Ltd., 2024-04-30) Konieczna, Iwona; Miałkowska, Kozaryna Milena; Akademia Pedagogiki Specjalnej im. Marii Grzegorzewskiej w Warszawie
The pandemic COVID -19 necessitated the introduction of distance learning in many countries, including Poland. For teachers and students, this meant a major change and several challenges (both technical and psychological) that they had to face. Students with autism spectrum disorder (ASD) and their teachers are concerned. The aim of the present study was to find out the opinions of teachers about teaching children with ASD during the COVID-19 pandemic. The study was conducted at a time when the situation in Poland was very bad due to the epidemic and distance education was introduced. The survey involved 276 teachers, 144 of whom worked daily with a student with autism spectrum disorder (ASD) and 132 of whom worked with students with other than ASD special educational needs and disabilities (SEND). The results showed that teachers working with students with autism spectrum disorder were more likely to feel annoyed during the pandemic, less engaged in their work, and less likely to help others. Although teachers saw the benefits of distance learning, most felt that students with autism spectrum disorder did better in traditional schools.
Clashes of knowledge: ‘Green deal’ concepts and challenges for sustainable rural systems
(Polskie Towarzystwo Geograficzne, 2024) Wójcik, Marcin; Dmochowska-Dudek, Karolina; University of Lodz, Department of Regional and Social Geography, Poland
The content-related scope of the article includes primarily an attempt to take a broad look at the issues of research topics undertaken in research on sustainable development of rural areas. This topic is of great importance in the context of global environmental problems and various concepts of the ‘green deal’ included in the development policies of countries, primarily the EU member states. These issues were the subject of considerations during the 30th Annual Colloquium of the Commission on the Sustainability of Rural Systems of the International Geographical Union, which took place on June 5–9, 2023 at the University of Lodz, at the Faculty of Geographical Sciences. To comprehensively identify the topic, the methodology of content analysis of the abstracts submitted by the authors was used. This approach and the analysis of the sample of research papers presented at the conference made it possible to identify key issues related to sustainable development of rural areas. The approach used shed light on the relationship between society and nature, and revealed a variety of perspectives and solutions proposed by researchers from around the world. An attempt to integrate the thoughts of many scientists (conference participants) and highlight basic issues in the field of sustainable development of rural areas led to the construction of a model of environmental research in relation to the geographical specificity of understanding reality. This specific thought study (synthesis of views) highlights the importance of different perspectives and knowledge systems in understanding the foundations of sustainable rural development. The content-related analysis of the conference abstracts revealed four groups of processes influencing the sustainable development of rural areas, i.e. exploitation of natural resources and its social context, changes in land use, building social awareness of environmental threats and the evolution of connections between urban and rural areas.
MgO Modified by X2, HX, or Alkyl Halide (X = Cl, Br, or I) Catalytic Systems and Their Activity in Chemoselective Transfer Hydrogenation of Acrolein into Allyl Alcohol
(MDPI, 2024-07-03) Gliński, Marek; Ulkowska, Urszula; Kaszkur, Zbigniew; Łomot, Dariusz; Winiarek, Piotr; Nacci, Angelo; Faculty of Chemistry, Warsaw University of Technology, Warsaw, Poland; Institute of Physical Chemistry, Polish Academy of Sciences, Warsaw, Poland
A new type of catalyst containing magnesium oxide modified with various modifiers ranging from bromine and iodine, to interhalogen compounds, hydrohalogenic acids, and alkyl halides have been prepared using chemical vapor deposition (CVD) and wet impregnation methods. The obtained systems were characterized using a number of methods: determination of the concentration of X− ions, surface area determination, powder X‐ray diffraction (PXRD), surface acid–base strength measurements, TPD of probe molecules (acetonitrile, pivalonitrile, triethylamine, and n‐butylamine), TPD‐MS of reaction products of methyl iodide with MgO, and Fourier transform infrared spectroscopy (FTIR). The catalysts’ activity and chemoselectivity during transfer hydrogenation from ethanol to acrolein to allyl alcohol was measured. A significant increase in the activity of modified MgO (up to 80% conversion) in the transfer hydrogenation of acrolein was found, while maintaining high chemoselectivity (>90%) to allyl alcohol. As a general conclusion, it was shown that the modification of MgO results in the suppression of strong basic sites of the oxide, with a simultaneous appearance of Brønsted acidic sites on its surface. Independently, extensive research on the reaction progress of thirty alkyl halides with MgO was also performed in order to determine its ability to neutralize chlorinated wastes.
Keyboard as a Stimulator in Timbre Recognition Training
(IADIS Press, 2023) Rosiński, Adam; Uniwersytet Warmińsko-Mazurski w Olsztynie
This paper presents the results of a research conducted in a group of Youth Palace in Olsztyn participants. Two different keyboards were used in the experiment to teach how to recognize the timbres of selected musical instruments. Obtained results clearly showed that musical education with the use of keyboards significantly develops timbre hearing of children and youth. The research group performed much better in the tests in comparison with the control group. A danger appearing during this kind of training is the listener getting used to a given timbre (sample). Big part of psychoacoustic research is limited to acoustic stimuli not related to the art of music in a real way, which does not allow the use of this type of research and stimuli in musical didactics. The experiment presented in this paper is based on generating musical sounds that have worked well in education.
