Evaluating ski resort investment projects: adapting to new climatic challenges

Climate change is significantly impacting ski centers in Central Europe. Warmer winters are leading to less snowfall and more rain, which can result in lower revenues for these resorts. To address this challenge, implementing technologies like higher-capacity ski lifts and artificial snowmaking systems has become necessary. This paper, evaluates a specific investment project in the southern region of Czechia. By analyzing historical data, current market prices of technology, and financial forecasts, I assess the potential investment in new technology. The results indicate that investing in such technology could effectively mitigate the effects of climate change on ski centers

Number of severe bleeding complications according to classification used: Is unified classification of bleeding complications really necessary?

Background: To compare the number of severe periprocedural bleeding complications from the total number of bleeding complications associated with diagnostic selective coronary an­giography or percutaneous coronary intervention (PCI) when using different classifications (TIMI, GUSTO, PLATO, BARC) and to relate these classifications to real hemodynamic status of evaluated patients. Methods: We analyzed data from 106 patients who underwent invasive procedure for ischemic heart disease (selective coronary angiography/PCI) and suffered from any type of bleeding complication. Results: The number of bleeding according to impacts on hemodynamic status and consequent treatment shows that 54.7% of all bleedings did not need any specific therapy. Bleeding leading to death, hemorrhagic shock, hemodynamic instability, administration of blood transfusion, surgical procedure and local treatment occurred in 6.6%, 1.9%, 5.7%, 14.2%, 2.8%, and 14.2%, respectively. The results comparing bleeding classifications demonstrate that the rate of severe bleeding complications may increase up to 4 times when different classifications are used on the same group of patients (TIMI 9.4%, GUSTO 15.1%, PLATO 39.2% and BARC 35.9%). The power of association between severe bleeding determined by these classifications and real hemodynamic compromise using Kendall’s tau-c correlation is –0.4106 (95% CI –0.599 to –0.222), –0.5355 (95% CI –0.718 to –0.353), –0.5513 (95% CI –0.729 to –0.374) and –0.7552 (95% CI –0.897 to –0.612) for TIMI, GUSTO, PLATO and BARC, respectively. Conclusions: The data show significant dependence of percentage of severe periprocedural bleeding complications on selected classification. The strongest association between severe bleeding and real hemodynamic status was found for BARC classification as this classification seems to be promising for future general use
