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.  相似文献   

Redefinition of gestational diabetes mellitus: implications for laboratory practice in Croatia

An increasing prevalence of gestational diabetes has become a very challenging task in prenatal care worldwide. International Association of Diabetes and Pregnancy Study Groups (IADPSG) has recently issued recommendations on the diagnosis and classification of hyperglycaemia in pregnancy. These recommendations, the first to provide harmonised, evidence-based criteria for the diagnosis and classification of diabetes in pregnancy, are currently being discussed and accepted worldwide by the relevant authorities. As the acceptance of the proposed criteria has major implications for both clinical and laboratory settings, a concerted action towards necessary changes in practice has to be carefully planned and adjusted to national health-care specificities.IADPSG criteria have been strongly advocated by the Croatian Perinatology Society, resulting in a new strategy for the detection and diagnosis of hyperglycaemic disorders in pregnancy.To address the respective laboratory requirements, in April 2012, the Croatian Chamber of Medical Biochemists appointed a Working Group to provide a standardised procedure for the diagnosis of gestational diabetes, applicable to all laboratories involved in prenatal care, in both primary and specialised health-care facilities.In this paper we discuss key laboratory-related issues regarding succesful implementation of the IADPSG criteria in Croatia.  相似文献   

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

Š. Anđelinović  I. Anterić  E. Škorić  Ž. Bašić 《国际体育史杂志》2013,30(5):708-721

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.  相似文献

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

Vesna Skrbinjek  Janez Šušteršič  Dušan Lesjak 《Tertiary Education and Management》2018,24(2):168-186

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.  相似文献   

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

Tomáš Kasper  Dana Kasperová 《History of education》2018,47(3):321-348

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.  相似文献   

Alternative models of entrance exams and access to higher education: the case of the Czech Republic     

Tomá? Kone?ny  Josef Basl  Jan Myslive?ek  Natalie Simonová 《Higher Education》2012,63(2):219-235

The study compares the potential effects of a university admission exam model based on program-specific knowledge and an alternative model relying on general study aptitude (GSA) in the context of a strongly stratified educational system with considerable excess of demand over supply of university education. Using results of the Sonda Maturant 1998 survey, we show that in the specific context of the Czech Republic, displaying the above characteristics in the given period, an admission exam model based on general study aptitude tests may improve the access of talented individuals with lower socioeconomic status to university education. Our simulations show that with the GSA model (provided the model assumptions are met), the relative chances of an applicant with a university-educated father would be only by one-fourth higher than the relative chances of a student with a less educated father, as compared to the more than a one-third difference in case of the model emphasizing program-specific knowledge. The odds ratio for the GSA model is by 28% points lower for mother’s education.  相似文献   

The role of emotions in student teachers’ professional identity     

Inge Timoštšuk  Aino Ugaste 《欧洲师范教育杂志》2012,35(4):421-433

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.  相似文献
