The article presents a study of applying the proposed method of cluster analysis to support purchasing decisions in the welding industry. The authors analyze the usefulness of the non-hierarchical method, Expectation Maximization (EM), in the selection of material (212 combinations of flux and wire melt) for the SAW (Submerged Arc Welding) method process. The proposed approach to cluster analysis is proved as useful in supporting purchase decisions.

We describe a method of calculating sharp lower and upper bounds on the expectations of linear combinations of kth records Expressem in the Gini mean difference units of the original i.i.d. observations. In particular, we provide sharp lower and upper bounds on the expectations of kth records and their differences. We also present the families of distributions which attain the bounds in the limit.

When tapping in synchrony with an isochronous sequence of beats, participants respond automatically to an unexpectedly early or late beat by shifting their next tap; this is termed thephase correction response(PCR). A PCR has also been observed in response to unexpected perturbations of metrical subdivisions of a beat, which suggests that participants have temporal expectancies for subdivisions to occur at particular time points. It has been demonstrated that a latent temporal expectancy at 1/2 of the inter-beat interval (IBI) exists even in the absence of explicit duple subdivision in previous IBIs of a sequence. The present study asked whether latent expectancies at 1/3 and 2/3 of the IBI can be induced by a global experimental context of triple subdivision, and whether a local context of consistently phase-shifted triple subdivisions can induce different expectancies. Using the PCR as the dependent variable, we find weak evidence for latent expectancies but strong evidence for context-induced shifts in expectancies. These results suggest that temporal referents between beats, which typically are linked to simple ratios of time spans, are flexible and context-dependent. In addition, we show that the PCR, a response to expectancy violation, is independent of and sometimes contrary to the simultaneous phase adaptation required by a change in subdivision timing.

Poczucie skuteczności odgrywa ważną rolę na subiektywne odczuwanie dobrostanu przez jednostkę. Poziom skuteczności jest ściśle związany z oczekiwaniami w trakcie wykonywania każdej czynności. Większe oczekiwania powinny wyzwalać energię i wpływać na skuteczniejsze efekty kształcenia, bądź wykonywanej pracy zawodowej. Celem niniejszego artykułu jest analiza poczucia skuteczności z życia studentów, którzy rozpoczęli studia na kierunkach ścisłych i humanistycznych. Badania wykonano na podstawie własnego projektu zrealizowanego wśród 383 studentów Politechniki Rzeszowskiej i Uniwersytetu Rzeszowskiego. Do badań wykorzystano metodę sondażu diagnostycznego i standaryzowanego narzędzia badającego poziom skuteczności z życia z wykorzystaniem Skali Uogólnionej Własnej Skuteczności (Generalized Self-Effficency Scale – GSES) opracowanej przez Ralfa Schwarzera i Matthiasa Jeruzalema i przygotowanej w polskiej adaptacji przez Zygrfyda Juczyńskiego. Badania pokazały, że poczucie skuteczności z życia studentów kształtował się na poziomie umiarkowanym. Wzięto pod uwagę następujące zmienne niezależne: uczelnia, płeć, wiek, miejsce zamieszkania i zamożność respondentów. W dwóch badaniach istniało zróżnicowanie w poziomie istotności statystycznej w zależności od rodzaju uczelni i płci badanych. Natomiast biorąc pod uwagę średnią, studenci z Politechniki Rzeszowski przejawili nieco wyższy poziom poczucia skuteczności w przeciwieństwie do studentów z Uniwersytetu Rzeszowskiego. Wnioski z badań stanowią wyzwanie dla sytemu edukacji, nauczycieli, wychowawców na wszystkich poziomach kształcenia, aby wszelkie zmiany, systematycznie wprowadzane do programów kształcenia mogły odzwierciedlać potrzeby studentów.

The sense of effectiveness plays an important role in the subjective perception of well-being by an individual. It closely relates the level of effectiveness to the expected performance of each activity. Higher expectations should release energy and affect effective results of education or professional work. The aim of this article is to analyze the sense of effectiveness in life of students who started their studies in science and humanities. For this purpose, I have carried research out based on an own project taken among 383 students of the Rzeszów University of Technology and The University of Rzeszow. The research used a diagnostic survey method, and a standardized tool to measure the level of effectiveness in life using the Generalized Self-Efficency Scale (GSES) developed by Ralf Schwarzer and Matthias Jerusalem and prepared in Polish adaptation by Zygrfyd Juczyński. The research showed that the students' sense of effectiveness in life was moderate. The following independent variables were taken into account: university, gender, age, place of residence and the wealth of the respondents. In two studies, there was a difference in the level of statistical significance depending on the type of university and the gender of the respondents. On the other hand, taking into account the average, students from the Rzeszów University of Technology showed a slightly higher level of sense of effectiveness in contrast to students from the University of Rzeszów. The conclusions from the research constitute a challenge for the education system, teachers at all levels of education, so that any changes, systematically introduced to the education programs, could reflect the needs of students to a greater extent.

The aim of this study was to analyse potential differences between Belgian and Polish consumers in intention to consume chocolate. Research procedure is based on the Theory of Planned Behaviour (TPB), which is a method applied in investigation of performance where a problem of incomplete volitional control exists. In this context, the chosen method seems adequate especially after two modifications. First, is inclusion of an affective component, which is analysed through the preference score and the taste index. A second modification lays in addition of self-stated habit. The results are presented in cross-country design. In the current study, the TPB model is only a part of the framework in which affective, conative, and cognitive dimensions are jointly analysed. The proposed Cognition and Affection-Related Behavioural Intention (CARBI) model enables a comparison of the strength of influences between countries in the total sample. Data evaluation by correlation, multiple regression and the analysis of variance is implemented. Results show a clear difference in perceived behavioural control, while the attitude component is a strong predicting variable for both countries. Preference for chocolate does not add to predictive power of consumer intentions in contrast to the self-stated habit. The region of living and personality of respondents are considered as good predictor variables.

Perception is a constructive mental process, which cannot be considered impersonally. Similarly, music cannot be cognised solely on the basis of its score, since its coming into being is strictly connected to the activation of human memory and sound imagination. The patterns that emerge from the sounds of heard music enable the listener to draw conclusions regarding the structures those sounds embody. However, such conclusions are accompanied by a degree of uncertainty, which concerns not just the perceived moment of the heard music, but also the way in which it is represented in the listener’s memory. Perception is an inferential, multi-layered, uncertain process, in which particular patterns seem more likely than others. Mental representations of those probabilities lie behind such essential musical phenomena as surprise, tension, expectation and pitch identification, which are fixed elements of theperception of music. The aim of the present article is to describe the essence of three selected types of music modelling, based on spectral anticipation (Shlomo Dubnov), based on memory (Rens Bod), and exploiting the dynamic character of music to obtain information (Samer Abdallah and Mark Plumbley). All these models take account of the element of uncertainty that accompanies the perception of music; hence they make use the foundations of information theory and statistical analysis as measurement ‘tools’. The use of these tools makes it possible to obtain numerical rates, which inform us of the degree of predictability of the musical structures being analysed. One crucial advantage of these methods is the possibility of evaluating them in respect to the use of real musical structures, deriving from actual music, and not abstract structures formed for the purposes of research. We obtain cognitive insight into the analysed music by employing methods of a mathematical provenance, and so we have the possibility of examining music whilst taking account of the role of the listener, but with the use of objectivised methods.

The article is an attempt to recreate the Greek thinking about the phenomenon of hope. Multilevel ambivalence has been found. Firstly, as expecting either something good or something bad. Then, as a negative hope (in the sense of unreasonable, irrational and leading to crisis) or a positive hope (in the sense of justified, rational and enabling salvation). Finally, as a morally good or bad hope, depending upon the ethical evaluation of its subject. Also, a correlation of fear and hope has been found. The problem of referring hope to time has been put forward. In this context, the views of Hesiod, Thucydides, Plato, Aristotle and the Stoics have been considered.

Artykuł jest próbą odtworzenia myślenia Greków o fenomenie nadziei. Stwierdzona zostaje wielopoziomowa jej ambiwalencja. Najpierw jako spodziewanie się albo czegoś dobrego, albo czegoś złego. Następnie jako nadzieja negatywna (w znaczeniu nieuzasadniona, nierozumna i prowadząca do zguby) bądź pozytywna (w znaczeniu uzasadniona, rozumna i umożliwiająca ocalenie). Na koniec jako nadzieja moralnie dobra bądź zła w zależności od etycznej oceny jej przedmiotu. Stwierdzona zostaje też korelacja strachu i nadziei. Postawiony zostaje problem odniesienia nadziei do czasu. W tym kontekście są rozważane są poglądy Hezjoda, Tukidydesa, Platona, Arystotelesa i stoików.

Background. In the recent years, the birth rate among teenage girls has decreased. Although more and more teenagers, especially girls, begin their sexual lives earlier, their knowledge on contraception is usually unsatisfactory and a significant number of adolescents either do not use contraception or use unreliable contraception methods. The lack of sex education at schools leads to teenage students’ lacking knowledge and support in this matter. Material and methods. The tool applied in the research was a previously prepared survey questionnaire entitled Teachers’ and class tutors’ opinions on teen motherhood serving as the research tool. Results. The interviewees are convinced that in order to prevent pregnancies among adolescent girls, teenagers should be treated individually and provided with reliable knowledge and support. On the other hand, the respondents deem recommendable to warn teenagers of negative consequences that having sex brings and of stigmatisation the sexually active and pregnant girls face. Moreover, the interviewed teachers find it appropriate to promote only sympto-thermal contraception methods. Conclusions. The inconsistency and high restrictiveness in teachers’ opinions affect their involvement in teenagers’ sex education and their support towards pregnant students and underage mothers.

Wprowadzenie. W ostatnich kilkunastu latach w Polsce obniża się skala urodzeń dzieci przez nastoletnie dziewczęta. Dzieje się tak pomimo tego, że nastąpił wzrost częstości wczesnego rozpoczynania życia seksualnego przez młodzież, zwłaszcza dziewczęta, niezadowalający jest poziom wiedzy młodzieży na temat antykoncepcji oraz występuje znacząca skala nastolatków niekorzystających z antykoncepcji, bądź stosujących zawodne metody. Ze względu na abstynencyjny model edukacji seksualnej w szkole, uczniowie nie otrzymują dostatecznego wsparcia w omawianym zakresie. Materiał i metody. Narzędziem zastosowanym w badaniu był w cześniej przygotowany kwestionariusz ankiety pt. Opinie nauczycieli i wychowawców na temat macierzyństwa nastolatek. Wyniki. Stwierdzono, że badani z jednej strony są przekonani, iż w celu z apobiegania wczesnym ciążom należy traktować nastolatków w sposób podmiotowy, dostarczać im rzetelnej wiedzy oraz udzielać wsparcia. Z drugiej strony uznają za pożądane straszenie nastolatków negatywnymi konsekwencjami współżycia i piętnowanie osób aktywnych seksualnie oraz ciężarnych dziewcząt. Uznają przy tym za właściwe promowanie jedynie objawowo-termicznych metod antykoncepcji. Wnioski. Ta niespójność i duża skala restrykcyjności poglądów nie pozwala na optymizm w ocenie udziału nauczycieli w edukacji seksualnej młodzieży, ani ich roli w realnym wsparciu uczennic w sytuacji ciąży i macierzyństwa.
