Off-field spectacle: Polish contemporary art and the national game (1921–2012)     

Przemysław Strożek 《Soccer & Society》2017,18(4):476-496

This essay examines the relationships between football and art in Poland since the launch of the first 1921 Polish Football Championship until 2012, when the European Cup was held in Poland and Ukraine, testifying to a veritable craze for the national game, and cementing football’s place in cultural discourse. From pre-war painterly references to football, through Neo-avant-garde tendencies in the 1970s, to young Polish art, football has signified multiple meanings within national/transnational and gender discourse. Through the lens of artistic references to football this paper aims to comment on the cultural and social conditions around masculinity and star culture, and to reflect the broader social and political currents of contemporary Poland.  相似文献   

Influence of short-term inertial training on swimming performance in young swimmers

The aim of this study was to evaluate the influence of dry-land inertial training (IT) on muscle force, muscle power, and swimming performance. Fourteen young, national-level, competitive swimmers were randomly divided into IT and control (C) groups. The experiment lasted four weeks, during which time both groups underwent their regular swimming training. In addition, the IT group underwent IT using the Inertial Training Measurement System (ITMS) three times per week. The muscle groups involved during the upsweep phase of the arm stroke in front crawl and butterfly stroke were trained. Before and after training, muscle force and power were measured under IT conditions. Simultaneously with the biomechanical measurements on the ITMS, the electrical activity of the triceps brachii was registered. After four weeks of training, a 12.8% increase in the muscle force and 14.2% increase in the muscle power (p?<?.05) were noted in the IT group. Moreover, electromyography amplitude of triceps brachii recorded during strength measurements increased by 22.7% in the IT group. Moreover, swimming velocity in the 100?m butterfly and 50?m freestyle improved significantly following the four weeks of dry-land IT (?1.86% and ?0.76%, respectively). Changes in the C group were trivial. Moreover, values of force and power registered during the ITMS test correlated negatively with the 100?m butterfly and 50?m freestyle swimming times (r value ranged from ?.80 to ?.91). These results suggest that IT can be useful in swimming practice.  相似文献

Monitoring Acoustic Emission in an Epidemiological Pilot Study of a Collection of Wooden Objects

ABSTRACT

This experimental program, implemented by the Managing Collection Environment Initiative at the Getty Conservation Institute, has provided data about the response of historic objects to changes in relative humidity (RH). Alongside other less sensitive documentation techniques (visual observation, physical measurements, photography, and 3D scanning), acoustic emission (AE) was monitored for six historic, museum-like wooden objects exposed to gradually increasing RH variations. Quantitative calibration of AE sensors and an anti-correlation measuring scheme to reduce environmental noise allowed the AE system to effectively trace micro-damage development caused by environmentally induced stress. Using an epidemiological approach, with respect to sample selection and experimental protocol, the obtained results can be used to explore the acceptable range of climate fluctuations for museum collections. The study’s well-controlled environmental protocol also allowed for the examination of the concept of ‘proofed fluctuation’ by the analysis of object response to reoccurring conditions.  相似文献

A mathematical camp for bright pupils     

Barbara Rabijewska  Mieczysław Trąd 《Educational Studies in Mathematics》1985,16(1):41-57

The purpose of this paper is to present briefly the idea of a mathematical camp for bright pupils and to consider some features of the activities on such a camp.Investigations carried out in the period of 1980–1982 have allowed us to establish a list of activity forms, found to be the most effective, to recommend for use on mathematical camps for bright pupils.  相似文献   

Plasma centrifugation does not influence thrombin-antithrombin and plasmin-antiplasmin levels but determines platelet microparticles count

Introduction

Centrifugation is an essential step for plasma preparation to remove residual elements in plasma, especially platelets and platelet-derived microparticles (PMPs). Our working hypothesis was that centrifugation as a preanalytical step may influence some coagulation parameters.

Materials and methods

Healthy young men were recruited (N = 17). For centrifugation, two protocols were applied: (A) the first centrifugation at 2500 x g for 15 min and (B) at 2500 x g for 20 min at room temperature with a light brake. In protocol (A), the second centrifugation was carried out at 2500 x g for 15 min, whereas in protocol (B), the second centrifugation involved a 10 min spin at 13,000 x g. Thrombin-antithrombin (TAT) and plasmin-antiplasmin (PAP) complexes concentrations were determined by enzyme-linked immunosorbent assays. PMPs were stained with CD41 antibody and annexin V, and analyzed by flow cytometry method. Procoagulant activity was assayed by the Calibrated Automated Thrombogram method as a slope of thrombin formation (CAT velocity).

Results

Median TAT and PAP concentrations did not differ between the centrifugation protocols. The high speed centrifugation reduced the median (IQR) PMP count in plasma from 1291 (841-1975) to 573 (391-1010) PMP/µL (P = 0.001), and CAT velocity from 2.01 (1.31-2.88) to 0.97 (0.82-1.73) nM/min (P = 0.049). Spearman’s rank correlation analysis showed correlation between TAT and PMPs in the protocol A plasma which was (rho = 0.52, P < 0.050) and between PMPs and CAT for protocol A (rho = 0.74, P < 0.050) and protocol B (rho = 0.78, P < 0.050).

Conclusion

Centrifugation protocols do not influence the markers of plasminogen (PAP) and thrombin (TAT) generation but they do affect the PMP count and procoagulant activity.Key words: cell-derived microparticles, blood coagulation tests, centrifugation, preanalytical phase  相似文献

The learning preferences of Enterprise System consultants: towards the preferred learning pattern     

Przemys?aw?LechEmail author  Anna?Zamojska 《知识管理研究与实践》2017,15(2):316-324

This paper presents the results of a combined quantitative–qualitative study that explored the learning patterns of IT consultants involved in the implementation of Enterprise Systems (ES). The study was carried out in a multinational IT consulting company that specialises in Enterprise System consulting and has offices in Germany, the UK, the US, Poland and China. The study revealed the preferred learning pattern of IT consultants, which starts with introductory learning, preferably executed in the form of instruction-based training, followed by the preparation of a prototype to process and sustain the knowledge, and continues with hands-on learning during real-life projects. Learning during projects was identified as the most important knowledge source, as it is the only way actually to gain experience. The experience itself was considered to be the final outcome of the learning process, and it is the main asset of a consulting enterprise.  相似文献
