Demokracja i wartości w wychowaniu. O epistemologicznym statusie doświadczenia w pragmatyzmie
2019
Znaczenie doświadczenia w wychowaniu w postulatach pedagogiki pragmatyzmu jest powszechnie znane. Wiele miejsca tej problematyce poświęcił John Dewey. Celem artykułu jest odpowiedź na pytanie o ograniczenia w wykorzystywaniu doświadczenia w procesie wychowania. Odpowiedź na to pytanie jest wpisana w epistemologiczne zagadnienie relacji między doświadczeniem a teorią. W pierwszym punkcie są przywołane najważniejsze kwestie dotyczące pojęć doświadczenia, demokracji i wartości w wychowaniu. W drugim punkcie opisana jest rola doświadczenia w pragmatyzmie w kontekście behawioryzmu, zwłaszcza behawioryzmu społecznego. W trzecim punkcie przedstawione są w skrócie epistemologiczne dyskusje nad stat…
Fast Graph Filters for Decentralized Subspace Projection
2020
A number of inference problems with sensor networks involve projecting a measured signal onto a given subspace. In existing decentralized approaches, sensors communicate with their local neighbors to obtain a sequence of iterates that asymptotically converges to the desired projection. In contrast, the present paper develops methods that produce these projections in a finite and approximately minimal number of iterations. Building upon tools from graph signal processing, the problem is cast as the design of a graph filter which, in turn, is reduced to the design of a suitable graph shift operator. Exploiting the eigenstructure of the projection and shift matrices leads to an objective whose…
Bayesian Checking of the Second Levels of Hierarchical Models
2007
Hierarchical models are increasingly used in many applications. Along with this increased use comes a desire to investigate whether the model is compatible with the observed data. Bayesian methods are well suited to eliminate the many (nuisance) parameters in these complicated models; in this paper we investigate Bayesian methods for model checking. Since we contemplate model checking as a preliminary, exploratory analysis, we concentrate on objective Bayesian methods in which careful specification of an informative prior distribution is avoided. Numerous examples are given and different proposals are investigated and critically compared.
Estimating with kernel smoothers the mean of functional data in a finite population setting. A note on variance estimation in presence of partially o…
2014
In the near future, millions of load curves measuring the electricity consumption of French households in small time grids (probably half hours) will be available. All these collected load curves represent a huge amount of information which could be exploited using survey sampling techniques. In particular, the total consumption of a specific cus- tomer group (for example all the customers of an electricity supplier) could be estimated using unequal probability random sampling methods. Unfortunately, data collection may undergo technical problems resulting in missing values. In this paper we study a new estimation method for the mean curve in the presence of missing values which consists in…
Asymptotic and bootstrap tests for subspace dimension
2022
Most linear dimension reduction methods proposed in the literature can be formulated using an appropriate pair of scatter matrices, see e.g. Ye and Weiss (2003), Tyler et al. (2009), Bura and Yang (2011), Liski et al. (2014) and Luo and Li (2016). The eigen-decomposition of one scatter matrix with respect to another is then often used to determine the dimension of the signal subspace and to separate signal and noise parts of the data. Three popular dimension reduction methods, namely principal component analysis (PCA), fourth order blind identification (FOBI) and sliced inverse regression (SIR) are considered in detail and the first two moments of subsets of the eigenvalues are used to test…
Values and Personal Life Investment in Middle-Age: Measures and Relations
2015
The present study analyzed the factor structure of Schwartz Value Survey (SVS; 46 items) and the personal life investment (PLI; 10 items) scale, as well as the mutual relations between these two measures. The 50-year-old participants (n = 217–224) were drawn from the ongoing Finnish Jyväskylä Longitudinal Study of Personal and Social Development. For the SVS, the confirmatory factor analysis (CFA) supported the 14-factor structure: achievement, tradition, stimulation, hedonism, security, conformity, power, universalism (with sub-factors of societal concern, tolerance and protecting nature), benevolence (with sub-factors of caring and dependability) and self-direction (with sub-factors of au…
The Psychological Foundations of Management in Family Firms: Values, Biases, and Heuristics
2021
Considering the heterogeneity of family firm behaviors as reflecting the values, biases, and heuristics of individuals, we discuss the implications of the psychological foundations of management in family firms. We develop a conceptual framework for investigating how the values, biases, and heuristics of family and nonfamily members affect strategic decision-making and the outcomes of family firms. To advance the field, we put forward some relevant questions and offer a future research agenda at the intersection of the psychological foundations of management and family business.
Age-Related Reference Ranges for Fetal Foot Length
2000
AIM The aim of this study was to establish age-dependent reference ranges for fetal foot length with gestation as well as for the femur/foot length ratio, based on a mathematical growth model. METHOD In a prospective cross-sectional study of 610 pregnancies with sonographically confirmed gestational age (< 12 weeks' gestation), fetal biometry was performed in addition to measurements of fetal foot length between 12 and 42 completed weeks of gestation. Reference ranges for the fetal foot and for the femur/foot length ratio were constructed with an overall coverage of 90% of the measured data, using a previously established method of determining reference bands for growth parameters. RESULTS …
The role of parental expectations and students' motivational profiles for educational aspirations
2016
Abstract The present study examined the stability and change of students' motivational profiles from Grade 7 (Time 1) to Grade 9 (Time 2), using task values and self-concepts of ability in mathematics, Finnish language, and arts as indicator variables. The study also examined the effects of students' (Grade 7: N = 231; Grade 9: N = 237) motivational profiles and of their parents' educational expectations at Grade 7 on their short- and long-term educational plans at Grade 9, controlling for gender and academic achievement. The latent profile analysis identified four motivational profiles: (1) low motivation group; (2) high motivation group; (3) math-motivated group; (4) practical group, wh…
Domains of Convergence of Kam Type Iterations for Eigenvalue Problems
1999
The KAM technique was first introduced to deal with small denominator problems appearing in perturbation of invariant tori in classical mechanics [1, 2]. Similar methods were later applied to many different problems, like e.g. eigenvalue problems for time dependent problems in the Floquet representation [3, 4, 5, 6]. Most of the known results are valid for sufficiently small perturbation of some simple (integrable) system. The phenomena arising for large perturbations, in particular critical perturbations at which a given torus loses its stability, have been discussed in the framework of some approximate schemes inspired in renormalization group ideas [7, 8, 9]. In this framework, an iterat…
