The paper describes the process of developing sensory performance: Sense-Action. Memories of children and teenagers living in Litzmannstadt Ghetto – Anna Skorecki, Dawid Sierakowiak and Lolek Lubinski – are used as inspiration, but also narrative and experiential matrix for the performance’s structure. Between 2013 and 2016 three versions of the project, different in terms of techniques used and creative strategies were developed. Each was performed in a direct correlation with three chosen traditions in theatre studies – semiotics, anthropology and cognitive studies/phenomenology – which supported the exploration in performative correlation of the individual memory and memory of trauma mediated by the narrative. At the same time, the transition between the research contexts was not categorical. The structure of the performance was growing with subsequent editions, allowing on the one hand recognizing the places where the paradigms disconnect, and, on the other, the potential ways of correlating them. In the paper I analyse the interdependence of creative and research strategies as a potential teaching tool. The conclusions serve to indicate the potential benefits and risks of double involvement in dance and theatre, and hence the need to share two different perspectives.

In the studies on selection and population genetics of forest trees that include the analysis of genotype × environment interaction (GE), the use of biplot graphs is relatively rare. This article describes the models and analytic methods useful in the biplot graphs, which enable the analyses of mega-environments, selection of the testing environment, as well as the evaluation of genotype stability. The main method presented in the paper is the GGE biplot method (G - genotype effect, GE -genotype × environment interaction effect). At the same time, other methods have also been referred to, such as, SVD (singular value decomposition), PCA (principal component analysis), linear-bilinear SREG model (sites regression), linear-bilinear GREG model (genotypes regression) and AMMI (additive main effects multiplicative interaction). The potential of biplot method is presented based on the data on growth height of 20 European beech genotypes (Fagus sylvatica L.), generated from real data concerning selection trials and carried out in 5 different environments. The combined ANOVA was performed using fixed- -effects, as well as mixed-effects models, and significant interaction GE was shown. The GGE biplot graphs were constructed using PCA. The first principal component (GGE1) explained 54%, and the second (GGE2) explained more than 23% of the total variation. The similarity between environments was evaluated by means of the AEC method, which allowed us to determine one mega-environment that comprised of 4 environments. None of the tested environments represented the ideal one for trial on genotype selection. The GGE biplot graphs enabled: (a) the detection of a stable genotype in terms of tree height (high and low), (b) the genotype evaluation by ranking with respect to the height and genotype stability, (c) determination of an ideal genotype, (d) the comparison of genotypes in 2 chosen environments.

The central task of this research was to choose the age at which stands of growing timber should be harvested. The choice governs how long each stand must continue to earn interest, and also governs the size of the total inventory that must be maintained to sustain the annual harvest. It is a problem that calls for analysis of biological as well as economic relationships over time, and has intrigued economists for more than two centuries. The paper presents the theoretical background and results of economic optimization of the rotation age of a single stand. It analyses the timber production function depending on rotation age, growth, cost and other characteristics of forest, as well as the costs of land. The prerequisite for achieving the economic optimum of the rotation age of a stand is to balance the current increase in the total timber production value (growth and yield) and the value of opportunity costs from delaying cutting till the next year. This paper demonstrates how this economically optimum rotation age can be calculated, and how it varies according to the biological growth and economic parameters of the forest.

Small banded pine weevil Pissodes castaneus is one of the most dangerous pests of Pinus sylvestris plantations and thickets. The lack of effective and environmentally safe methods of limiting the number of the pest justified to undertake the studies aimed at the laboratory and field evaluation of biological activity of entomopathogenic fungus Beauveria bassiana used to reduce the numbers of small banded pine weevil. In laboratory, the beetles were reared on the sections of fresh Scots pine twigs that were treated with five suspensions containing from 1 × 104 to 1 × 108 conidia of B. bassiana in 1 ml. During the 3-week rearing, insect mortality was determined and median lethal concentration LC50 was calculated. The field treatments consisted of spraying 4-year-old P. sylvestris trees with two formulations of fungus containing 1 × 108 conidia ml−1 of suspension. Treatments consisted of spraying 4-year-old P. sylvestris trees with two fungus formulations containing 1 × 108 conidia ml−1. High insecticidal activity of B. bassiana was found because the pathogen caused the death of 14-94% of P. castaneus beetles, LC50 = 6.51 × 105 conidia ml−1. Field treatments did not result in the reduction of plant damage caused by small banded pine weevil; therefore, the spraying of trees with B. bassiana cannot be recommended to protect the young stands of P. sylvestris against pest.

The author of the review discusses in detail six chapters of Piotr Szwed's book /Oddaleniec/ Poezja Bolesława Leśmiana wobec romantyzmu polskiego. He focuses on the eponymous link between Bolesław Leśmian and the the legacy of Polish Roman- ticism. Also analyzed are Leśmian's references to works by poets such as Adam Mickiewicz and Juliusz Słowacki. The quality of the reviewed study and its position within the existing research have been highly appraised. Publikacja dofinansowana przez katedry literaturoznawcze Instytutu Filologii Polskiej UŁ

In the theory of management sciences the beginning of the 21st century is the time of evolution from strategic management to knowledge management in knowledge-based organizations [Mikuła 2006, pp. 15-39]. Meanwhile, in the Polish economic and administrative reality, the basic form of management is bureaucracy, described in the early 20th century by Max Weber. As it results from the research conducted with regard to management attitudes and styles in organizational units of PGL LP (the State Forests National Forest Holding), like in other national organizations, this form of management is very frequent. However, as compared to other companies with equally frequent autocratic management, in PGL LP we can notice growing importance of participatory (democratic) management, which proves that, despite the hierarchy and a certain negligence with regard to human resource management, the organization is undergoing some evolutionary changes. And, in spite of presence of autocratic attitudes, these are changes for the better. W teorii nauk o zarządzaniu początek XXI wieku to czas ewolucji od zarządzania strategicznego do zarządzania wiedzą w organizacjach opartych na wiedzy [Mikuła 2006, s. 15-39]. Tymczasem w polskiej rzeczywistości gospodarczej i administracyjnej podstawową formą zarządzania jest biurokracja opisana na początku XX wieku przez Maxa Webera. Jak wynika z przeprowadzonych badań w zakresie postaw i stylów kierowania w jednostkach organizacyjnych PGL LP, podobnie jak i w innych krajowych organizacjach ta forma zarządzania występuje często. Jednak na tle innych firm, gdzie równie często występuje zarządzanie autokratyczne, w PGL LP widoczny jest jednak wzrost znaczenia zarządzania partycypacyjnego (demokratycznego), co świadczy o tym, że pomimo obowiązującej hierarchii, oraz pewnego zaniedbania zarządzania zasobami ludzkimi, organizacja ta ulega pewnym ewolucyjnym zmianom. I pomimo występowania nadal postaw autokratycznych, są to zmiany na lepsze.
