Szkoły stowarzyszeniowe w perspektywie lokalnej polityki oświatowej gmin
2019
Fundamentalnym osiągnięciem decentralizacyjnej polityki państwa w latach 90. XX w. był powrót oświaty do wymiaru lokalnego. Gminy przejęły odpowiedzialność za zakładanie, likwidowanie i przekształcanie szkół na swoim terenie. Jest to najważniejsze ich zadanie w kreowaniu lokalnej polityki oświatowej. Uwarunkowania demograficzne ostatnich lat, niż demograficzny, spadek liczby uczniów w szkołach oraz wzrastające koszty utrzymania placówek oświatowych to główne determinanty przekazywania przez gminy szkół lokalnym stowarzyszeniom
Klapać na pyszczysku, czyli o śląskiej leksyce i frazeologii dotyczącej mówienia
2019
The article discusses selected lexical units found in the dialects of Silesia, which refer to the act of speaking. It examines more than 190 tokens and collocations whose common denominator is the meaning of ‘speaking’. Analyzed are units referring to the content of the expression (with the main semantic component ‘to talk nonsense’), as well as those referring to physical aspects of the act of speaking, such as the clarity and accuracy of articulation (‘to speak indistinctly’, ‘to stutter’), the pace of speaking (‘to speak fast’, ‘to speak slowly’), also the tone, pitch, and intensity of the voice (‘to speak softly’, ‘to say shrilly’). An analysis of the collected material shows that these…
Opis frazeologii w słowniku gwarowym Jana Karłowicza a późniejsza praktyka leksykograficzna
2020
The aim of the article is to show how to list and develop phraseology in the oldest Polish dialect dictionary: A Dictionary of Polish Dialects by Jan Karłowicz, and then discuss the placement of phraseology in the macro- and microstructure of later, 20th century selected dialectal dictionaries. Therefore, the article is an overview of the tradition of lexical development and study of phraseology in dialectal dictionaries (on the example of Silesian Dialect Dictionary, Polish Dialects Dictionary by Polish Academy of Sciences, the dictionary of Bernard Sychta, Dictionary of Ostróda, Warmia and Mazury Dialects).
Miejsce frazeologii w słownikach gwarowych
2016
The aim of this article is to research the ways of developing phraseology and its emplacement into the macro- and microstructure in selected dialectal dictionaries (academic and popular). The first part is an overview of the phraseology, as included in introductions to the dictionaries. In the second part, using specific examples, the author discusses how the methodological and editorial assumptions adopted by dictionary authors/editors are followed in practice. The study of introductions and analysis of the lexical material reveal that in the absence of clearly framed methodological assumptions and detailed editorial guidelines on how to present phraseology in dialectal dictionaries, the q…
Model selection using limiting distributions of second-order blind source separation algorithms
2015
Signals, recorded over time, are often observed as mixtures of multiple source signals. To extract relevant information from such measurements one needs to determine the mixing coefficients. In case of weakly stationary time series with uncorrelated source signals, this separation can be achieved by jointly diagonalizing sample autocovariances at different lags, and several algorithms address this task. Often the mixing estimates contain close-to-zero entries and one wants to decide whether the corresponding source signals have a relevant impact on the observations or not. To address this question of model selection we consider the recently published second-order blind identification proced…
Surrogate-assisted evolutionary multiobjective shape optimization of an air intake ventilation system
2017
We tackle three different challenges in solving a real-world industrial problem: formulating the optimization problem, connecting different simulation tools and dealing with computationally expensive objective functions. The problem to be optimized is an air intake ventilation system of a tractor and consists of three computationally expensive objective functions. We describe the modeling of the system and its numerical evaluation with a commercial software. To obtain solutions in few function evaluations, a recently proposed surrogate-assisted evolutionary algorithm K-RVEA is applied. The diameters of four different outlets of the ventilation system are considered as decision variables. Fr…
Generalizability and Simplicity as Criteria in Feature Selection: Application to Mood Classification in Music
2011
Classification of musical audio signals according to expressed mood or emotion has evident applications to content-based music retrieval in large databases. Wrapper selection is a dimension reduction method that has been proposed for improving classification performance. However, the technique is prone to lead to overfitting of the training data, which decreases the generalizability of the obtained results. We claim that previous attempts to apply wrapper selection in the field of music information retrieval (MIR) have led to disputable conclusions about the used methods due to inadequate analysis frameworks, indicative of overfitting, and biased results. This paper presents a framework bas…
Seeking Technical Debt in Critical Software Development Projects : An Exploratory Field Study
2016
In recent years, the metaphor of technical debt has received considerable attention, especially from the agile community. Still, despite the fact that agile practices are increasingly used in critical domains, to the best of our knowledge, there are no studies investigating the occurrence of technical debt in critical software development projects. The results of an exploratory field study conducted across several projects reveal that a variety of business and environmental factors cause the occurrence of technical debt in critical domains. Using Grounded Theory method, these factors are categorized as ambiguity of requirement, diversity of projects, inadequate knowledge management, and res…
Supporting Agile Development by Facilitating Natural User Interaction with Executable Formal Specifications
2011
Agile development benefits from fast feedback from various stakeholders. If implemented in a suitable way, formal methods can enhance the agile development process. With an executable formal specification, it is possible to analyse and simulate the behaviour of the target system before it is being built. However, for the users' and developers' natural participation in the development process, it is necessary to use a real end-user interface and bind it to the execution environment being used in the simulations and animations. This requires, though, that the execution model used to simulate the specification is appropriately changed to facilitate the use of these user interfaces. The authors…
Remote Attestation of Software and Execution-Environment in Modern Machines
2015
The research on network security concentrates mainly on securing the communication channels between two endpoints, which is insufficient if the authenticity of one of the endpoints cannot be determined with certainty. Previously presented methods that allow one endpoint, the authentication authority, to authenticate another remote machine. These methods are inadequate for modern machines that have multiple processors, introduce virtualization extensions, have a greater variety of side effects, and suffer from nondeterminism. This paper addresses the advances of modern machines with respect to the method presented by Kennell. The authors describe how a remote attestation procedure, involving…
