Reliability and Validity of Finger Strength and Endurance Measurements in Rock Climbing

Purpose: An advanced system for the assessment of climbing-specific performance was developed and used to: (a) investigate the effect of arm fixation (AF) on construct validity evidence and reliability of climbing-specific finger-strength measurement; (b) assess reliability of finger-strength and endurance measurements; and (c) evaluate the relationship between finger flexor all-out test scores and climbing ability. Methods: To determine the effect of AF, 22 male climbers performed 2 maximal strength and all-out tests with AF (shoulder and elbow flexed at 90°) and without AF (shoulder flexed at 180° and elbow fully extended). To determine reliability, 9 male climbers completed 2 maximal strength tests with and without AF and an all-out and intermittent test without AF. Results: The maximal strength test without AF more strongly determined climbing ability than the test with AF (r² = .48 and r² = .42 for sport climbing; r² = .66 and r² = .42 for bouldering, respectively). Force and time variables were highly reliable; the rate of force development and fatigue index had moderate and low reliability. The maximal strength test with AF provided slightly higher reliability than without AF (intraclass correlation coefficient [ICC] = 0.94, ICC = 0.88, respectively). However, smaller maximal forces were achieved during AF (484 ± 112 N) than without AF (546 ± 132 N). All-out test average force had sufficiently high reliability (ICC = 0.92) and a relationship to sport climbing (r² = .42) and bouldering ability (r² = .58). Conclusion: Finger strength and endurance measurements provided sufficient construct validity evidence and high reliability for time and force parameters. Arm fixation provides more reliable results; however, the position without AF is recommended as it is more related to climbing ability.     

Enrichment of live unlabelled cardiomyocytes from heterogeneous cell populations using manipulation of cell settling velocity by magnetic field

The majority of available cardiomyocyte markers are intercellular proteins, limiting our ability to enrich live cardiomyocytes from heterogeneous cell preparations in the absence of genetic labeling. Here, we describe enrichment of live cardiomyocytes from the hearts of adult mice in a label-free microfluidic approach. The separation device consisted of a vertical column (15 mm long, 700 μm diameter), placed between permanent magnets resulting in a field strength of 1.23 T. To concentrate the field at the column wall, the column was wrapped with 69 μm diameter nickel wire. Before passing the cells through the column, the cardiomyocytes in the cell suspension had been rendered paramagnetic by treatment of the adult mouse heart cell preparation with sodium nitrite (2.5 mM) for 20 min on ice. The cell suspension was loaded into the vertical column from the top and upon settling, the non-myocytes were removed by the upward flow from the column. The cardiomyocytes were then collected from the column by applying a higher flow rate (144 μl/min). We found that by applying a separation flow rate of 4.2 μl/min in the first step, we can enrich live adult cardiomyocytes to 93% ± 2% in a label-free manner. The cardiomyocytes maintained viability immediately after separation and upon 24 h in culture.     

Skeleton Changes Induced by Horse Riding on Medieval Skeletal Remains from Croatia

Skeletal remains of 35 individuals from the Croatian excavation site Kamen Most – Kaldrma from the fourteenth to fifteenth centuries were analyzed anthropologically. Due to specific skeletal characteristics, eight of them were analyzed in great detail in this study. The results of additional analysis indicated that all bone elements, except pelves, of all eight persons belonged to males. All pelvic girdle have characteristics of female sex and pronounced muscle attachments that are both indicative of horse riding. All eight persons had at least two of six changes on femora indicative of horse riding. Vertebrae of seven persons (one person did not have preserved vertebrae) have Schmorl's nodes. Signs of advanced osteoarthritis were found on all joints in all eight persons. All of them also have visible signs of periostitis especially on lower extremities. Pathological signs of trauma were found in five persons. Two of them had skull fractures and the rest had fractures of extremities which are also characteristic for horse riders. The average age of all eight persons was above 45 years at death. DNA analysis confirmed male sex for seven individuals. The results were additionally confirmed by later archeological findings of tombstones with illustrations of horse riders.     

Political preferences and public funding of tertiary education during the economic crisis

This article analyses how political preferences, which are co-determined by the beliefs of decision-makers and influences of interest groups and the general public, affect the decisions to maintain or cut public funding for tertiary education during the economic crisis. Our sample included 29 European countries which we divided into two groups depending on the level of public funding for tertiary education before the crisis, which we used as a measure of revealed political preferences. We then observed the differences in changes in public tertiary education funding during the crisis between these two groups of countries using five different indicators. Three of the five indicators show that countries with a stronger political preference for tertiary education public funding cut their spending on tertiary education to a lesser extent (or even increased spending) during the economic crisis.     

The Bat'a Company in Zlín: a shoe company or a school company?

The first part of the study focuses on the characteristics and analysis of Zlín as an example of a company town. Life in the company town is characterised as a means of forming ‘a new man’ in Bat'a’s Zlín. The second section analyses the aims of worker education in Bat'a’s Zlín (in the so-called Bat'a school of work) and highlights the methods and conditions of education for young men and women, focusing on the area of company education. The third part deals with the question of rationalisation (or scientific management) – an extended concept in the production, social and economic areas of interwar Czechoslovakia – in the context of Bat'a’s Zlín. Attention is given to the technocratic movement and to the problems of psycho-technology and its application in the production process and employee selection in the Bat'a Company.

The role of emotions in student teachers’ professional identity

This paper presents findings of a qualitative interview study of the role of emotions in the professional identity of student teachers. Strong positive and negative emotions (mostly related to pupils and supervisors) were expressed about personal teaching experiences. The results confirm that emotions play an important role in social learning and, therefore, influence the development of professional identity. The two most important findings were that negative emotions exercised the strongest influence and that supervisors neglected the role of positive emotions as a support for learning. The study supports the concept that it is important for teacher educators to help student teachers understand their emotional experiences (focusing foremost on positive factors in their experience) and to develop the ability to express their own emotions in addition to understanding the emotions of others.
