Distribution of the AMPD1 C34T polymorphism in Polish power-oriented athletes

The aims of this study were to determine the distribution of the AMPD1 genotype among groups of high-level Polish power-oriented athletes, and to investigate potential associations between genetic polymorphism in exon 2 of the AMPD1 gene and power-oriented athlete status. Altogether, 158 male Polish power-oriented athletes were genotyped by PCR-RFLP. The genetic control group comprised 160 unrelated male volunteers. We observed significant differences in genotype distribution when all 158 athletes (89.25% CC, 10.75% CT, 0.00% TT; P = 0.0025) were compared with controls (75.00% CC, 23.75% CT, 1.25% TT). A significant deficiency of the T allele was noted in all subgroups (short-distance runners: 5.21%, P = 0.032; short-distance swimmers: 5.56%, P = 0.031; weightlifters: 5.36%, P = 0.024) compared with controls (13.13%), while this trend was even stronger when the frequency of the T allele was compared between controls and all 158 athletes (5.38%, P = 0.0007). Our results indicate a lower frequency of the AMPD1 exon 2 T34 allele in elite Polish power-oriented athletes. Our data suggest that the C allele may help athletes to attain elite status in power-oriented sports.     

HERIe: A Web-Based Decision-Supporting Tool for Assessing Risk of Physical Damage Using Various Failure Criteria

ABSTRACT

HERIe is a web-based decision-supporting software tool to facilitate the management of collection environments by precise assessment of climate-induced risk of physical damage to vulnerable objects. The software translates the relative humidity and temperature data recorded in the environment of the analysed object into a strain history experienced by it, and estimates the risk of physical damage using selected failure criteria. As all information is pre-calculated for the user, no engagement in complex and time-consuming numerical simulations is required. HERIe is available for testing at herie.mnk.pl. Detailed information on the methodologies used by the software is available at the above website which also contains tutorial climates. The current work aims at refining HERIe by selecting the damage criteria not only from laboratory studies but also from direct monitoring damage accumulation in objects, especially using the acoustic emission method. The software has been expanded to include moisture-induced response of parchment to support managing environments in libraries and archives.     

Educational reform and the public: Two case studies of Poland and Saskatchewan (Canada)

The involvement of the public in educational reform processes in modern democratic societies primarily serves the purpose of politically legitimizing the reform agenda. This study examines the rationales implicitly or explicitly submitted to the public to explain why educational reforms in the two countries should be endorsed. Although differences in the political culture caution against a hasty comparison of the two case studies, a number of politico-economic similarities allow for a valid juxtaposition. In Poland the context of socio-political and economic renewal prompted the reformers to emphasize the human-capital model which heightened public awareness and participation in the debate surrounding the reform. Public involvement in Saskatchewan was negatively affected for mainly two reasons. First, the government evidently manipulated public input by various means and thereby appears to have predetermined the outcome. Second, the rationale for the reform, based on a free-market model, tightened the linkage between the needs of the labour market and the mandate of the schools. As a result, public interest and participation was greatly diminished.

Zusammenfassung Die Beteiligung der Öffentlichkeit an Reformen auf dem Gebiet der Erziehung in den modernen demokratischen Gesellschaften dient hauptsächlich der politischen Legitimierung der Reformpläne. In dieser Studie werden die der Bevölkerung offen oder unterschwellig vermittelten Gründe untersucht, warum den erzieherischen Reformen in beiden Ländern zugestimmt werden sollte. Obwohl die Unterschiede in der politischen Kultur Anlaß zur Vorsicht vor einem voreiligen Vergleich der beiden Fallstudien geben, so sprechen einige wirtschaftspolitische Ähnlichkeiten für eine sinnvolle Nebeneinanderstellung. In Polen führte der Zusammenhang sozialpolitischer und wirtschaftlicher Erneuerung dazu, daß die Reformer das Modell des menschlichen Kapitals, das das öffentliche Bewußtsein und die Teilnahme an der Debatte über die Reformen verstärkte, besonders betonten. Die öffentliche Beteiligung in Saskatchewan bekam aus zwei Gründen einen negativen Beigeschmack. Erstens manipulierte die Regierung offensichtlich in verschiedener Hinsicht die Beiträge der Öffentlichkeit, und sie scheint damit das Ergebnis vorbestimmt zu haben. Zweitens stärkten die Gründe für die auf ein Modell der freien Marktwirtschaft gegründeten Reformen die Verbindungen zwischen dem Bedarf des Arbeitsmarktes und dem Mandat der Schulen. Als Folge davon reduzierte sich das öffentliche Interesse und die Beteiligung erheblich.

Résumé La participation du public aux processus de réforme éducative dans les sociétés démocratiques modernes sert essentiellement à légitimation politique du calendrier de réforme. Cette étude examine la raison d'être soumise implicitement ou explicitement au public et analyse pourquoi les réformes éducatives doivent être adoptées dans les deux pays. Bien que les divergences de cultures politiques mettent en garde contre une comparaison hâtive des deux études de cas, certaines correspondances politico-économiques permettent une juxtaposition valide. En Pologne, le contexte de la rénovation socio-politique et économique a pressé les réformateurs à mettre en valeur le modèle de capital humain qui a rehaussé l'information et la participation du public dans le débat autour de la réforme. La participation du public dans le Saskatchewan a été entravée pour deux raisons. Premièrement, il semblerait que le gouvernement ait manipulé les investissements publics de différentes manières et qu'il ait par cela prédéterminé le résultat obtenu. Deuxièmement, la légitimité de la réforme, orientée vers un modèle de marché libre, a renforcé les liens entre les besoins du marché de l'emploi et le mandat des écoles. Par conséquent, l'intérêt et la participation du public ont été considérablement affaiblis.

     

Multimedia and interactivity in distance learning of resuscitation guidelines: a randomised controlled trial

The aim of the study was to conduct a comparative analysis of three forms of knowledge transfer online, taking into account the long-term knowledge growth rate and the satisfaction of students surveyed in respect to distance learning. The cohort of participants for this survey were students of the first degree, studying in the Emergency Medical Services. The authors created three e-learning courses in basic and advanced resuscitation procedures. The level of course participants’ satisfaction was analysed, as well as the knowledge growth rate measured three times: 7, 30 and 90 days, respectively, after finishing the course. The level of satisfaction in all the groups surveyed was comparable. The growth rate for knowledge was the highest in group C in the second and third survey, respectively (30 and 90 days after the end of the course), and a significant difference in favour of course C was demonstrated one month after finishing classes.     

Differences in teachers’ comments on classroom events as indicators of their professional development

This study aims at identifying indicators of schoolteachers’ professional development by learning teachers’ perceptual and thinking capabilities of classroom events as reflected in their comments. The analysis of comments produced by novice and expert teachers on videotaped lesson activities, based mainly on the grounded theory strategy, revealed that expert teachers are more sensitive towards certain instructional events and to general teaching strategy used by the model teacher than novice teachers. The findings of this study might be useful for promoting student teachers’ professional sensitivity towards relevant features of classroom instruction and atmosphere in pre-service teacher education programs.     

Eye-tracking verification of the strategy used to analyse algorithms expressed in a flowchart and pseudocode

The results of qualitative and quantitative investigations conducted with individuals who learned algorithms in school are presented in this article. In these investigations, eye-tracking technology was used to follow the process of solving algorithmic problems. The algorithmic problems were presented in two comparable variants: in a pseudocode and flowchart. The eye-tracking data resulted in both qualitative (films registering the gaze paths) and quantitative measures, which allowed the detection and interpretation of the differences in the task-solving strategies between those who found the correct answer and those that did not. The results confirmed a hypothesis that use of the formal notation characteristic of a programming language for presenting algorithms is often a practical difficulty in the process of solving even simple tasks. This study opens a new direction of research; they show that eye-tracking technology can be used to optimise the educational process of learning programming.     

Peer review: The experience and views of early career researchers

This paper presents selected findings from the first year of a 3‐year longitudinal study of early career researchers (ECRs), which sought to ascertain current and changing habits in scholarly communication. Specifically, the aims of the paper are to show: (1) how much experience and knowledge ECRs had of peer review – both as authors and as reviewers; (2) what they felt the benefits were and what suggestions they had for improvement; (3) what they thought of open peer review (OPR); and (4) who they felt should organize peer review. Data were obtained from 116 science and social science ECRs, most of whom had published and were subject to in‐depth interviews conducted face‐to‐face, via Skype, or over the telephone. An extensive literature review was also conducted to provide a context and supplementary data for the findings. The main findings were that: (1) most ECRS are well informed about peer review and generally like the experience, largely because of the learning experiences obtained; (2) they like blind double‐peer review, but would like some improvements, especially with regards to reviewer quality; (3) most are uncomfortable with the idea of OPR; and (4) most would like publishers to continue organizing peer review because of their perceived independence.     

Modeling parameters that characterize pacing of elite female 800-m freestyle swimmers

Pacing offers a potential avenue for enhancement of endurance performance. We report here a novel method for characterizing pacing in 800-m freestyle swimming. Websites provided 50-m lap and race times for 192 swims of 20 elite female swimmers between 2000 and 2013. Pacing for each swim was characterized with five parameters derived from a linear model: linear and quadratic coefficients for effect of lap number, reductions from predicted time for first and last laps, and lap-time variability (standard error of the estimate). Race-to-race consistency of the parameters was expressed as intraclass correlation coefficients (ICCs). The average swim was a shallow negative quadratic with slowest time in the eleventh lap. First and last laps were faster by 6.4% and 3.6%, and lap-time variability was ±0.64%. Consistency between swimmers ranged from low-moderate for the linear and quadratic parameters (ICC = 0.29 and 0.36) to high for the last-lap parameter (ICC = 0.62), while consistency for race time was very high (ICC = 0.80). Only ~15% of swimmers had enough swims (~15 or more) to provide reasonable evidence of optimum parameter values in plots of race time vs. each parameter. The modest consistency of most of the pacing parameters and lack of relationships between parameters and performance suggest that swimmers usually compensated for changes in one parameter with changes in another. In conclusion, pacing in 800-m elite female swimmers can be characterized with five parameters, but identifying an optimal pacing profile is generally impractical.     

The Role of Universities in Stimulating Regional Development and Educating Global E´lites

At the start of the Twenty-First Century, European universities must play a number of roles in terms of social and economic development. In particular, they must increasingly serve as engines for local and regional development, thus filling a niche that only seems logical for them. At the same time, universities will form e´lites, particularly local e´lites; however, those universities that are world-class institutions will and should educate global e´lites. In performing the latter role, European universities in the Twenty-First Century will reassume a role, seized by American universities in the Twentieth Century, which they had successfully played in the Nineteenth Century.
