Opis:
This paper defines the concept of simple strategy and introduces three kinds of simple strategies: wealth-invariant, scale-invariant and "wealthier-accept more". For three commonly used utility function families: CARA, CRRA and DARA equivalent characterizations are obtained in terms of the corresponding simple strategy, in terms of the buying and selling price properties, and in terms of the utility function properties as expressed by Cauchy functional equations. Moreover, an extension of famous Pratt (1964) theorem is proved which involves buying price for a lottery as an alternative measure of comparative risk aversion. Additionally a number of propositions on both selling and buying price for a lottery and CRRA utility class are proved.

Opis:
The aim of the paper is to point out certain analogies between de Saussure’s theoretical reflection on the ontic properties of expressions and the corresponding old Chinese and Indian concepts. Following a review of de Saussure’s ideas, the author proceeds to present their Eastern analogues. The main focus is turned to the fact that the Chinese Moists as well as the Indian grammarians and philosophers elicited proportion as the key to the understanding of the mechanism of language. The Sanscrit grammarians, the philosophers of Mīmāṃsa as well as, most probably, Gongsun Long in China saw clearly the invariant and non-material nature of expressions. The Buddhist logicians and the Moists also pointed to the oppositional character of expressions as constitutive for language.

Opis:
We investigate univalent holomorphic functions f defined on the unit disk such that f() is a hyperbolically convex subset of ; there are a number of analogies with the classical theory of (euclidean) convex univalent functions. A subregion Ω of is called hyperbolically convex (relative to hyperbolic geometry on ) if for all points a,b in Ω the arc of the hyperbolic geodesic in connecting a and b (the arc of the circle joining a and b which is orthogonal to the unit circle) lies in Ω. We give several analytic characterizations of hyperbolically convex functions. These analytic results lead to a number of sharp consequences, including covering, growth and distortion theorems and the precise upper bound on |f''(0)| for normalized (f(0) = 0 and f'(0) > 0) hyperbolically convex functions. In addition, we find the radius of hyperbolic convexity for normalized univalent functions mapping into itself. Finally, we suggest an alternate definition of "hyperbolic linear invariance" for locally univalent functions f: → that parallels earlier definitions of euclidean and spherical linear invariance.

Opis:
This study aimed to verify the psychometric properties of the Polish version of the Grit-S questionnaire. Grit is understood here as the perseverance and passion for long-term goals, and it encompasses two dimensions: Consistency of Interest and Perseverance of Effort. The sample comprised N = 270 participants aged 18–34 (Mage = 20.79). We performed confirmatory factor analyses to verify the dimensional structure of grit, multi-group confirmatory factor analysis to compare the structure across gender, and correlation analysis to examine external validity (exploring the correlations between grit, procrastination, and well-being). Findings showed satisfactory parameters for Grit-S including: reliability, structural and external validity, and measurement invariance across gender groups. The results support the possibility of using the Grit-S questionnaire in research exploring the predictors of success.

Opis:
When the measurement errors may be assumed to be normal and independent from what is measured a subnormal model may be used. We define a linear and generalized linear hypotheses for these models, and derive F-tests for them. These tests are shown to be UMP for linear hypotheses as well as strictly unbiased and strongly consistent for these hypotheses. It is also shown that the F-tests are invariant for regular transformations, possess structural stability and are almost strongly consistent for generalized linear hypothesis. An application to a mixed model studied by Michalskyi and Zmyślony is shown.

Consequently, the possibility was investigated of using theories such as varying speed of light (VSL) and fractal mathematics to build a framework within which answers can be found to some of standard cosmological problems and physics theories on the basis of time non-homogeneity.

Opis:
Multi-Group Confirmatory Factor Analysis (MGCFA) demonstrated the deficiency of the four original European Commission (EC) items for consumer confidence. Fit of the MGCFA model was unacceptable and without scalar invariance, index comparison between study periods was not permissible. This provided clear motivation for a plausible alternative index specification to comply with requirements for single-dimensionality and meaning invariance throughout the study period. The MGCFA model using a new set of items demonstrated partial metric and partial scalar invariance. Using the structural equation framework, consumer confidence was revealed as strongly interrelated with unemployment forecast and durable goods purchase.

Opis:
The aim of this study (N = 713) was to adapt the Appearance Schemas Inventory–Revised into Polish and evaluate its psychometric properties. The ASI-R is a widely used tool for measuring appearance schemas, but it is currently not available in Polish. The adaptation of the ASI-R has the potential to fill this gap and encourage research in the Polish community. The validation of the scale was conducted on two separate samples of healthy adults. Although the results indicate that the Polish version of the scale, in contrast to the original one, exhibits a one-factor structure, its psychometric properties are robust. The scale demonstrates high internal consistency and sound construct validity, established through correlations with various aspects of psychosocial functioning, along with body image and sociocultural attitudes toward appearance. The scale seems to be gender-invariant and can be utilized in future studies that adopt a cognitive-behavioral approach to appearance schemas.
