Metoda zmian konkurencyjności Estebana - Marquillasa a specjalizacja regionu na przykładzie produkcji zwierzęcej w Polsce
2016
Analiza składników zmiany (ang. shift-share analysis) jest popularną techniką analizy gospodarek regionalnych. Mankamentem klasycznej analizy zmian strukturalnych jest to, że nie uwzględnia ona relacji pomiędzy konkurencyjnością a efektem zmian strukturalnych. Esteban - Marquillas w 1972 roku zaproponował zmianę klasycznego równania shift- share, wprowadzając kategorię homotetyczną badanego zjawiska, co pozwoliło na uwzględnienie efektu konkurencyjności oraz powiązań między poszczególnymi składowymi. Ta zmiana pozwoliła na oczyszczenie efektu zmian pozycji konkurencyjności z wpływu wszelkich lokalnych zmian strukturalnych. Celem artykułu jest przedstawienie analizy składników zmiany i możli…
New insights on the Carburangeli Cave speleogenesis: a flank margin cave in Northern Sicily (Italy)
2022
Flank margin caves form in coastal regions by mixing dissolution. Their development is controlled by the position of the freshsalt water mixing boundary, which in turn, is related to sea-level position. They are characterized by a typical cave pattern and cave-wall morphologies and represent good indicators of past sea levels. This contribution shows the results of recent studies conducted in the Carburangeli Cave, a small sub-horizontal cavity developed in Northern Sicily, close to Palermo. This cave was firstly known for paleontological and archaeological findings and for these reasons, along with its speleological and biological interest, a Nature Reserve has been instituted by the Sicil…
BENDAMUSTINE IN ASSOCIATION WITH RITUXIMAB AS SALVAGE THERAPY FOR SPLENIC MARGINAL ZONE LYMPHOMA
2010
At present, a prospectively validated treatment for SMZL is lacking. Despite this fact, splenectomy is still deemed to be the best choice for patients requiring treatment. Nevertheless, the high fraction of patients achieving a clinical response following splenectomy eventually relapses or progresses

Maradona and China: Perceptions and representations of a sports myth
2022
This article highlights specific aspects of the relationship between Maradona and the People���s Republic of China (PRC) to trace the development of the ���one-athlete brand��� in global sport and the construction of the ���foreign��� sports myth in China. These aspects include the aligned development of football in China and Maradona as an icon, manifested in the gap in the domestic space for Western athletic icons in China and Maradona���s rise during the 1986 World Cup; the political identity and interpretation of Maradona as a supporter of communist and socialist regimes amidst China���s opening and international integration; and the modern development of the Chinese sports machine and …

Management of Early Glottic Cancer Treated by CO2 Laser According to Surgical-Margin Status: A Systematic Review of the Literature
2021
Abstract Introduction Transoral laser microsurgery (TLM) is the treatment of choice for Tis-T2 squamous cell glottic carcinomas due to its advantages compared with open surgery and radiotherapy. However, the CO2 laser beam causes changes and damage on the specimens, making the histological assessment of resection margins, the gold standard for confirming radical tumor resection, sometimes difficult. Objective To assess the different ways to manage patients depending on the status of the histopathological margin according to recent studies to detect the most commonly shared therapeutic strategy. Data Synthesis We analyzed the literature available on the PubMed and Web of Science databases, i…
Can the adaptive Metropolis algorithm collapse without the covariance lower bound?
2011
The Adaptive Metropolis (AM) algorithm is based on the symmetric random-walk Metropolis algorithm. The proposal distribution has the following time-dependent covariance matrix at step $n+1$ \[ S_n = Cov(X_1,...,X_n) + \epsilon I, \] that is, the sample covariance matrix of the history of the chain plus a (small) constant $\epsilon>0$ multiple of the identity matrix $I$. The lower bound on the eigenvalues of $S_n$ induced by the factor $\epsilon I$ is theoretically convenient, but practically cumbersome, as a good value for the parameter $\epsilon$ may not always be easy to choose. This article considers variants of the AM algorithm that do not explicitly bound the eigenvalues of $S_n$ away …
