Multicollinearity
Opis:: Multicollinearity often occurs in regression analysis. Multicollinearity is a condition of correlation between independent variables which is a problem. One method that can overcome multicollinearity is the LASSO (Least Absolute Shrinkage and Selection Operator) method. LASSO is able to help to shrink multicollinearity and improve the accuracy of linear regression models. Estimators of LASSO parameters can be solved by the LARS (Least Angle Regression and Shrinkage) algorithm by algorithm which calculates the correlation vector, the largest absolute correlation value, equiangular vector, inner product vector, and determines the LARS algorithm limiter for LASSO. Selecting the best model using the Mallow’s C_p statistics. The smallest Mallow’s C_p value will be selected as the best model. LASSO method with a more detailed procedure with LARS algorithm and selecting the best model using the Mallow’s C_p statistics is discussed in this paper.

Opis:: The objective of the study was assessment of the function of the knee joint after ACL reconstruction using the LARS method and autogenous graft. The study was of a retrospective character and included 96 patients who had undergone reconstruction of the torn ACL. The study was conducted within 36–48 months after surgery. Methods: In order to compare the results of the ACL reconstruction performed with 2 types of grafts, the following instruments were used: Lysholm Knee Scoring Scale, SF 36v2 questionnaire for assessment of health-related quality of life, and Biodex System 4 for isokinetic muscle testing. Results: No differences in the evaluation of the quality of life measured using SF 36v2 questionnaire were observed between the LARS and ST GR groups. Using the Lysholm Scale, the distribution of knee function scores was compared according to the type of surgery. There are no grounds to confirm the differences in the distribution of knee function scores considering the type of graft ( p = 0.756). Isokinetic test showed a significant weakening of muscle strength in the operated limb, compared to the strength of the healthy limb. Conclusions: The type of graft used for ACL reconstruction does not exert an effect on the quality of life of patients or the level of their knee joint function. Extensor and flexor muscles strength of the knee joint was lower in the operated limb, irrespective of the type of graft used. Weak relationships were observed between the level of knee joint function and extensor muscle strength of this joint.

Opis:: The aim of the study was to assess static balance after reconstruction of the anterior cruciate ligament (ACL), using gracialis tendons graft (GR) or semi-tendinosus (ST), compared to patients treated with the Ligament Advanced Reinforcement System (LARS). The study was performed within 36 to 48 months after the surgery. Methods: The study included 96 patients. The LARS group consisted of 44 patients, control group operated with ST/GR tendons included 52 patients. The stabilometric platform Alpha was used to assess the static balance. Two 30-second trials in the double-leg stance position with eyes opened and closed were performed. The distribution of loads in a free standing was also assessed. Results: In the test with open eyes the subjects from the LARS group had a significantly longer center of pressure (COP) path, a higher mean velocity, a greater mean COP sway in foot in the lateral direction and a larger path area occupied by the COP graph. During the tests with eyes closed, a significant difference occurred in the mean displacement of COP in lateral direction – greater in the LARS group. In addition, all parameters deteriorated during the tests with eyes closed in both groups. Conclusions: In static balance assessed with eyes closed, more proprioceptive deficits may appear in the LARS group.

Tytuł:: The Rehn-Meidner model and its role in the Swedish economic policy

Opis:: This paper aims to describe the Swedish Rehn-Meidner model, the cause of its creation, its features and the reasons for changes in the Swedish economic policy over several decades. The model was developed by two Swedish economists in 1951 and it impacted the economic policy over the following decades. It was intended to facilitate achieving the goals of full employment, price stability, economic growth and equality in a redistribution of income through the policies of solidarity wage, restrictive economy, active labour market and marginal employment. The model was designed as a solution to the "overheating" of the Swedish economy in the 1950s. The implementation of the model initially proved to be successful. However, in the 1970s the economic policy began to be more influenced by trade unions, acting mainly in their own interest. Due to the growing globalisation other external factors, such as oil crises and negative demand shocks, started to have an increasing impact on Sweden. It was when economic decisions started to shift away from the recommendations of the model, and the "golden age" of the 1950s and 1960s came to an end. The following analysis intends to explain what was the model characterisation, how it influenced Sweden's development, and why the country economic policy has changed over time. It also states that despite changes in the economy, certain elements of the model have remained valid until today.
Celem artykułu jest przedstawienie szwedzkiego modelu polityki gospodarczej i płacowej Rehna-Meidnera, powodów jego powstania, jego cech, a także przyczyn zmian polityki gospodarczej Szwecji po kilkudziesięciu latach. Model ten, stworzony przez dwóch szwedzkich ekonomistów w 1951 r., stanowił podstawę polityki ekonomicznej przez kolejne dekady. Miał on ułatwić osiągnięcie celów pełnego zatrudnienia, stabilności cen, wzrostu gospodarczego i równości w redystrybucji dochodów poprzez politykę – solidarną płacową, restrykcyjną gospodarczą, aktywną na rynku pracy i marginalną w odniesieniu do zatrudnienia. Model został zaprojektowany z myślą o przegrzewającej się gospodarce, będącej problemem Szwecji w latach 50. Jego wdrożenie początkowo okazało się skuteczne, jednakże od lat 70. zaczęto coraz bardziej podporządkowywać politykę gospodarczą celom związków zawodowych, a wraz z postępującą globalizacją, coraz większy wpływ miały na Szwecję czynniki zewnętrzne, takie jak kryzysy naftowe i ujemne wstrząsy popytowe. Zaczęto wtedy odbiegać od zaleceń modelu przy podejmowaniu decyzji gospodarczych, a „złoty wiek” lat 50. i 60., dobiegł końca. Niniejsza analiza prowadzi do zrozumienia, czym model się charakteryzował, jaki miał wpływ na rozwój Szwecji, oraz dlaczego polityka gospodarcza uległa tam z czasem zmianie. Wykazano także, iż pomimo zmian w gospodarce kraju, elementy modelu wciąż pozostają aktualne.

Opis:: Wawrzyniec Engeström (altern. Lars Benzelstierna von Engeström) was a 19th-century Polish aristocrat with Swedish roots, a historian, writer and political activist who made it his life's mission to build bridges between Polish and Swedish culture. The rapprochement he sought was based on anti-German and anti-Russian sentiments. In his poems A Song about Our Stars (Pieśń o gwiazdach naszych, 1874, 1883) and The Vistula: A National Fantasy (Wisła – Fantazja narodowa, 1883) he drew on Wincenty Pol's Songs of Our Land (Pieśni o ziemi naszej). They all celebrated the idea of national unity based on historical memory, religion and custom. His inspiration came from Swedish Romantic literature, whose main works he translated into Polish.
