The penultimate goal for developing machine learning models in supply chain management is to make optimal interventions. However, most machine learning models identify correlations…
GPT has become financially literate: Insights from financial literacy tests of GPT and a preliminary test of how people use it as a source of advice
Paweł Niszczota, Sami Abbas
We assess the ability of GPT -- a large language model -- to serve as a financial robo-advisor for the masses, by using a financial literacy test. Davinci and ChatGPT based on GPT-…
KGTN-ens: Few-Shot Image Classification with Knowledge Graph Ensembles
Dominik Filipiak, Anna Fensel, Agata Filipowska
We propose KGTN-ens, a framework extending the recent Knowledge Graph Transfer Network (KGTN) in order to incorporate multiple knowledge graph embeddings at a small cost. We evalua…
The Young and the Old, the Fast and the Slow: A Large-Scale Study of Productivity Classes and Rank Advancement
Marek Kwiek, Wojciech Roszka
We examined a large population of Polish science, technology, engineering, mathematics and medicine (STEMM) scientists (N = 16,083) to study rank advancement and productivity. We u…
Mrs. Correct and Majority Colorings
Marcin Anholcer, Bartłomiej Bosek, Jarosław Grytczuk +3
A majority coloring of a directed graph is a vertex coloring in which each vertex has the same color as at most half of its out-neighbors. In this note we simplify some proof techn…
On b-acyclic chromatic number of a graph
Marcin Anholcer, Sylwia Cichacz, Iztok Peterin
Let be a graph. We introduce the acyclic b-chromatic number of as an analogue to the b-chromatic number of . An acyclic coloring of a graph is a map $c:V(G)\rightarr…
Dynamic pricing and discounts by means of interactive presentation systems in stationary point of sales
Marcin Lewicki, Tomasz Kajdanowicz, Piotr Bródka +1
The main purpose of this article was to create a model and simulate the profitability conditions of an interactive presentation system (IPS) with the recommender system (RS) used i…
On a Problem of Steinhaus
Marcin Anholcer, Bartłomiej Bosek, Jarosław Grytczuk +4
Let be a positive integer. A sequence of points in the unit interval is piercing if $\{x_1,x_2,\ldots,x_n\}\cap \left[\frac{i}{n},\frac{i+1}{n}…
Are Female Scientists Less Inclined to Publish Alone? The Gender Solo Research Gap
Marek Kwiek, Wojciech Roszka
In solo research, scientists compete individually for prestige, sending clear signals about their research ability, avoiding problems in credit allocation, and reducing conflicts a…
On compactness and fixed point theorems in partial metric spaces
Dariusz Bugajewski, Piotr Maćkowiak, Ruidong Wang
In this paper we examine two basic topological properties of partial metric spaces, namely compactness and completeness. Our main result claims that in these spaces compactness is…
Gender-Based Homophily in Research: A Large-Scale Study of Man-Woman Collaboration
Marek Kwiek, Wojciech Roszka
We examined the male-female collaboration practices of all internationally visible Polish university professors (N = 25,463) based on their Scopus-indexed publications from 2009-20…
Gender Disparities in International Research Collaboration: A Large-scale Bibliometric Study of 25,000 University Professors
Marek Kwiek, Wojciech Roszka
In this research, we examine the hypothesis that gender disparities in international research collaboration differ by collaboration intensity, academic position, age, and academic…
Enhancing the Demand for Labour survey by including skills from online job advertisements using model-assisted calibration
Maciej Beręsewicz, Greta Białkowska, Krzysztof Marcinkowski +4
In the article we describe an enhancement to the Demand for Labour (DL) survey conducted by Statistics Poland, which involves the inclusion of skills obtained from online job adver…
Estimation of the size of informal employment based on administrative records with non-ignorable selection mechanism
Maciej Beręsewicz, Dagmara Nikulin
In this study we used company level administrative data from the National Labour Inspectorate and The Polish Social Insurance Institution in order to estimate the prevalence of inf…
Note on the group edge irregularity strength of graphs
Marcin Anholcer, Sylwia Cichacz
We investigate the \textit{edge group irregularity strength} () of graphs, i.e. the smallest value of such that taking any Abelian group of order , th…
Linear bounds on nowhere-zero group irregularity strength and nowhere-zero group sum chromatic number of graphs
Marcin Anholcer, Sylwia Cichacz, Jakub Przybyło
We investigate the \textit{group irregularity strength}, , of a graph, i.e. the least integer such that taking any Abelian group of order , there exist…
