The aim of the thesis was to determine the four selected body measurements (body height , body weight , chest circumference , waist circumference) , measuring 3 functional tests (spirometry, dynamometry, Ruffini test) and an assessment of the level of motor skills for boys and girls aged between 13 and 15 years who fall into the general population of predolescence and adolescence school age . Using standard methods somatometric were selected 34 boys aged 13, 34 boys aged 15, 34 girls aged 13 and girls aged 34 to 15 years. The selected parameters were monitored: body length, weight, chest circumference and waist. The research findings also motoric performance of boys and girls aged between 13 and 15 years. Motor performance was tested by 14 motor tests. All this research was conducted at elementary and secondary schools in the South Bohemia Data were recorded in a previously prepared data sheets and were then statistically analyzed and processed in tables and graphs. All obtained data were compared with the results of earlier studies and may serve as reference materials for other researches. Furthermore, function tests were included in the results of the selected in this thesis (spirometry, dynamometry and Ruffini test). These functional tests are aimed primarily at first assessment of fitness of the respiratory and circulatory system in this age group.

Differences in the lifestyle of various populations may lead to changes in the shape of the long limb bones. This involves a reaction to the degree of mechanical and environmental stress acting upon these bones. Our work examined changes in the shape, proportions and size of the lower limb long bones (femur, tibia) over roughly the past five thousand years, or more precisely from the later phase of the Early Stone Age up to the 20th century. We studied the femurs and tibias of a total 520 adult individuals − 313 males and 207 females − from seven different periods or rather archaeological cultures. Our evaluation was based on the external, linear dimensions of the bones studied. Biological parameters were evaluated in relation to sexual dimorphism and lateral asymmetry. We paid special attention to the degree of flattening of the proximal third of the femoral and tibial shafts. Sexual dimorphism differed in individual populations. We found the least statistically significant parameters of sexual dimorphism in the oldest, Eneolithic, samples. In contrast, both sexes differed in the greatest number of parameters in the Early Middle Ages. Lateral asymmetry was most frequently demonstrated for the width dimensions in the case of the femoral and tibial diaphyses, which are in complete concurrence with...

After the first democratic election that took place in South Africa in 1994, numerous changes occurred within the labour force. The labour force has become increasingly diverse with individuals from different races, genders and ages now fulfilling various positions within organisations. Consequently, organisations have become more focused on managing this diverse workforce and eliminating stereotypes, and consequently discrimination that accompanies this diversity. Stereotypes that are formed within organisations can be based on various criteria and, if not addressed, can lead to various negative consequences for both the individual and the organisation. It therefore seems that stereotypes are an important topic to research, specifically within the unique South African context. The objective of this study was to explore the prevalent stereotypes and the experiences thereof among individuals working in selected South African organisations. Within the social constructivism paradigm using an emic perspective, qualitative research from both a phenomenological and hermeneutic approach was employed to achieve the objectives of this study. Both purposive and convenience sampling was used for the purpose of this study after utilising a multiple case study strategy. Employees of selected South African organisations (N = 336) were involved in this research study. These organisations formed part of the following employment sectors: banking, higher education institutions, mining, municipalities, nursing, police services, primary and secondary schools, and restaurant industry. Data was collected by making use of semi-structured interviews, and data analysis was achieved by means of thematic analysis. The results of this study indicated that individuals working in selected South African organisations are familiar with the meaning of stereotypes and that they are consciously aware of the origin of stereotypes. Results indicated that although not all of the participants have had direct experiences with stereotyped groups, they are well aware that stereotypes are also caused by indirect sources. The results of this study also illustrate that various stereotypes exist within selected South African organisations. It was explored on an out-group and in-group level. It was found that not only do employees stereotype others (out-group), they are also well aware of being stereotyped themselves (in-group). The most prevalent stereotypes were based on race, gender, age, occupation, and other work-related dimensions. Stereotypes based on race, gender and age were based on the internal dimensions of diversity. Stereotypes were also based on the external and organisational dimensions of diversity and included occupation, physical appearance, position, qualification, and duration in organisation. Interesting to note is that with in-group occupational stereotyping, most employees felt they are also stereotyped on their internal dimensional characteristics (race, gender and age). Stereotyped occupations include: academics, administration staff, educators, engineers, finance, human resources, librarians, mining, nursing, police and restaurant waitrons. The findings of this study also showed that when individuals experience in-group stereotypes, they react to these stereotypes on a cognitive, behavioural or emotional level. Results indicated that participants mostly reacted to stereotypes in a cognitive manner and most of these experiences were negative in nature. Recommendations with regard to future research and practice were made. Managers within organisations should eliminate stereotypes from organisational practices and decision-making by not focusing on irrelevant personal differences, but rather on performance-related information. Employees should be trained and educated by the organisation regarding stereotypes and the effects thereof. Employees should also be provided with an opportunity to interact with diverse people within the organisation. / PhD (Industrial Psychology), North-West University, Potchefstroom Campus, 2014
