Przepis art. 299 Kodeksu spółek handlowych jako funkcja prawa o niewypłacalności
2022
Przepis art. 299 Kodeksu spółek handlowych nawiązuje do treści art. 298 Kodeksu handlowego. Polski ustawodawca model spółki z ograniczoną odpowiedzialnością generalnie oparł na regulacji niemieckiej. Niemniej z uwagi na częste przypadki nadużywania formy spółki kapitałowej wprowadził szczególną odpowiedzialność członków zarządu. Regulacja art. 299 Kodeksu spółek handlowych przez lata była przedmiotem ożywionej debaty nauko-wej i wielu orzeczeń sądowych. W niniejszym opracowaniu stawiana jest teza, że wskazana regulacja jest funkcją prawa upadłościowego. Konsekwencją tej tezy jest wskazanie na zakres odpowiedzialności członka zarządu spółki z ograniczoną odpowiedzialnością, który podej-mie o…

Fish introductions and light modulate food web fluxes in tropical streams : a whole-ecosystem experimental approach
2016
Decades of ecological study have demonstrated the importance of top-down and bottom-up controls on food webs, yet few studies within this context have quantified the magnitude of energy and material fluxes at the whole-ecosystem scale. We examined top-down and bottom-up effects on food web fluxes using a field experiment that manipulated the presence of a consumer, the Trinidadian guppy Poecilia reticulata, and the production of basal resources by thinning the riparian forest canopy to increase incident light. To gauge the effects of these reach-scale manipulations on food web fluxes, we used a nitrogen (15N) stable isotope tracer to compare basal resource treatments (thinned canopy vs. con…
The economics of platform competition: compatibility, standardization and piracy
2013
This thesis studies the platform competition with compatibility, standardization and piracy. In the first chapter we study the role played by expectations, the strength of the network externality and product differentiation in the strategic decisions of the platforms regarding compatibility and price competition. The decision problem is modeled as a two-stage game. In the first stage platforms simultaneously and non-cooperatively choose the degree of compatibility and in the second stage platforms compete in prices. More specifically, we solve a two-stage game in which duopolists decide simultaneously and non cooperatively the degree of compatibility between their products and they compete …
Optical quality of hyperopic and myopic phakic intraocular lenses
2013
Aims: To assess and compare the optical quality of the myopic and hyperopic implantable collamer lens (ICL) from its wavefront aberrations for different powers and pupil diameters. Settings and Design: Prospective study. Material and Methods: The wavefront aberrations of two myopic (−3 and −6 diopters (D)) and two hyperopic V4b ICLs (+3 and +6D) were measured in vitro . To assess and compare the optical quality of different powers of ICLs, we analyzed the root mean square (RMS) of total higher order aberrations (HOAs), trefoil, coma, tetrafoil, secondary astigmatism, and spherical aberration at 3- and 4.5-mm pupil. In addition, the point spread functions (PSFs) of each ICL evaluated were ca…
The Role of Leadership in Complex Strategic Networks: Enabling Effect Versus Emergence
2013
In today's knowledge-based economy, the sources of competitive advantage lie more and more in webs of interactions among a variety of actors (such as firms, universities, research organizations, government institutions and so on), that over time originate the emergence of strategic networks. The paper aims to shed light on the determinants of network interaction and the ensuing processes of knowledge and resource transfer and circulation, on which the networkbased sources of competitive advantage are rooted. Accordingly, by means of the adoption of the complexity system perspective, on the one hand, we underscore the emergent nature of network interactions stemming from the self-organizing …

Modelling the evolution of periodicity in the periodical cicadas
2018
Background: Periodical cicadas (Magicicada spp.) have a life cycle that ends with the entire underground nymph population exhibiting a synchronized mass emergence to mate above ground. Previous studies have hypothesized that the periodical cicadas evolved from non-periodical cicadas by switching from a life-cycle length determined by body size to one determined by age. Questions: When can a mutation coding for fixed life-cycle length invade a resident population in which life-cycle length is variable? What determines the length of the fixed cycle? Methods: Numerical analysis of a mathematical model and simulations of an individual-based model. Results: If there is a sufficiently strong pred…
Hints of latent drivers investigating university student performance
2018
Job market, nowadays, asks for higher and higher skills and competences. Therefore, also the measurement and assessment of the university students performance are crucial issues for policy makers. Although the scientific literature provides several papers investigating the main determinants of university student performance, often results are very different, and they seem to hold just in very specific contexts. This paper aims to contribute to the international literature, focusing on the role of student specific characteristics, supporting the idea that unobservable variables (such as motivation, aptitudes or abilities) should be more investigated.
Student teachers' questioning behaviour which elicit conceptual explanation from students
2016
Getting students to explain their thinking is one of the big challenges in teachers’ work. Previous studies have analysed teacher questioning by focusing on amounts of different types of questions. In this study, I use questioning diagrams to see how questioning develops during the lessons. The data includes video recordings of student teachers’ mathematics lessons in secondary and upper secondary school. The data is analysed by constructing questioning diagram for each student teacher and locating conceptual explanations given by students. The lessons which included largest amount of conceptual explanations are further studied. In these lessons the student teachers had lengthy discussions …
