The socio-economic effectiveness of education

The authors discuss the factors which predetermine research into the effectiveness of education and the role of economics in educational research. Three fundamental research areas are identified: macroeconomic research into the relations between the national economy and culture and the educational system, economic aspects of the functioning of education, and cost-effectiveness in individual terms. The principles of planning and its implications for policy are discussed and the role of research on expenditure and costs defined. The effects of education are shown as being of two kinds, direct and indirect, and their relative importance for planning is considered and illustrated with examples from the authors' own research in Poland. Finally, the quantitative and qualitative aspects of extensive and intensive development policies and their relationship to overall national economic development are investigated and a number of conclusions drawn.

Résumé Les auteurs discutent les facteurs qui conditionnent la recherche consacrée au rendement de l'éducation ainsi que la rôle de l'économie dans la recherche sur l'éducation. Ils distinguent trois domaines fondamentaux de la recherche: premièrement, la recherche macro-économique portant sur les relations entre la culture ou l'économie nationale et le système d'éducation; deuxièmement les aspects économique du processus d'éducation; troisièmement les études de rendement en fonction du coût de l'éducation par téte. L'article discute les principes de la planification et ses implications en termes de politique de l'éducation et cherche à définir les effets de la recherche sur les dépenses et les coûts. On montre que les conséquences du processus d'éducation sont de deux types et leurs importance relative du point de vue de la planification est mise en évidence et illustrée par des exemples empruntés aux recherches des auteurs sur la Pologne. En conclusion, l'article éclaire les aspects tant quantitatifs que qualitatifs des politiques de développement extensif et intensif de l'éducation dans leurs relations au développement global de l'économie nationale pour en tirer un certain nombre de remarques finales. *** DIRECT SUPPORT *** A0010002 00003

     

Compressed sensing for real measurements of quaternion signals

The paper concerns compressed sensing methods in the quaternion algebra. We prove that it is possible to uniquely reconstruct – by ?₁ norm minimization – a sparse quaternion signal from a limited number of its real linear measurements, provided the measurement matrix satisfies so-called restricted isometry property with a sufficiently small constant. We also provide error estimates for the approximated reconstruction of a non-sparse quaternion signal from noisy and noiseless data.     

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     

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.     

Philosophy of education in post-Soviet societies of Eastern Europe: Poland,Lithuania and Slovenia

This article explores the role of philosophy of education in three post-Soviet societies of Eastern Europe: Poland, Lithuania and Slovenia. The characteristic themes and approaches of philosophical reflection about education in these societies are explored with reference to three periods: the pre-Soviet, Soviet and post-Soviet periods.     

Adult Learning – Providing Equal Opportunities or Widening Differences? The Polish Case

Educational activity among adults is not only a key factor of social development but also one of the most important priorities of public policies. Although large sums have been earmarked and numerous actions undertaken to encourage adult learning, many people remain educationally passive, a particularly acute problem in Poland. We point to the main cultural and economic determinants of educational passivity: the family environment, education, low earnings and job. Based on several years of research conducted within the Study of Human Capital in Poland project, we conclude that the Matthew effect is visible in the field of adult learning: better-educated people increase their educational capital, moving further away from those with a lower level of education. Comparison of the levels of self-evaluation of competences between educationally active and non-active adults of various levels of education indicates that the highest increase in evaluation occurs among less educated people. Owing to this group’s very low level of education, however, the scale of using the potential for educational activity is very low. The outcome of this is that the opportunities created by adult educational activity are not exploited to reduce social differences and instead it sometimes reinforces these differences.
