The population of this study was all the 4.255 children from 7 to 8 years old, male and female, regularly enrolled on the 37 elementary public city schools of Florianópolis, capital of Santa Catarina, a southern state of Brazil. The final sample was comprised by 417 children. The instrument used was the Movement Assessment Battery for Children - M-ABC. In order to characterize the prevalence and severity of the children s motor difficulties we used descriptive statistic of frequency distribution. To verify the prevalence associations of DCD among ages and gender we used the chi-squared test (X²) and the Cramer s V coefficient. To verify the difference between the groups (gender and age) in the total motor performance of the tasks of M-ABC we used the Variance Analysis (ANOVA two-way). To verify the types of motor abilities that the children performed better we utilized the ANOVA for repeated measures. To analyze the general differences between groups in a group of dependable variables (which comprise the types of abilities according to the M-ABC test) and later to fragment the analyses per dependable variable (manual dexterity, balance and ball skills), the Multivariate Variance Analysis was used, as well as to verify the interactive effects of the gender and age variables. Both the variance analyses were done using a model with two independent variables, gender and age group (2x2). For all the analyses the significance level was 5%. The results demonstrated that 10.8% of the children were identified with DCD and 12% presented risk of DCD. The results indicate that children showed more difficulties in the motor skills related to manual dexterity. The analysis revealed a statistically significant difference among genders and ages. Analyzing the individual dependent variables, separated through the analysis of the main effects, we can observe a statistically significant difference between genders and ages only in the ball skills. These results suggest that the boys presented a better performance in the ball skills, as well as the 8 year-old children. The prevalence of children with DCD in the city schools of Florianópolis, SC - Brazil exceeded the 4-6% of prevalence in 5 to 11 year-old children pointed by the literature. The early identification of children with motor difficulties is essential for the proper building of intervention strategies made by professionals in the area. / O objetivo deste estudo foi caracterizar o desempenho motor de crianças e investigar a prevalência de Desordem Coordenativa Desenvolvimental. A população deste estudo foi representada por todas as 4.255 crianças de 7 e 8 anos de idade, de ambos os sexos, regularmente matriculadas nas 37 escolas, básicas e desdobradas, da rede pública municipal da cidade de Florianópolis, capital de Santa Catarina. A amostra final foi composta por 417 crianças. O instrumento utilizado foi o Movement Assessment Battery for Children - M-ABC. Para caracterizar a prevalência e a severidade das dificuldades motoras das crianças foi utilizada estatística descritiva de distribuição de freqüência. Para verificar as associações de prevalência de DCD entre as idades e sexo, foi utilizado o teste do Qui-quadrado (X²) e o coeficiente de Cramer s V. Para verificar a diferença entre os grupos (sexo e idade) no desempenho motor total das tarefas do M-ABC foi utilizada a Análise de Variância (ANOVA two-way). Para verificar em que tipos de habilidades motoras as crianças demonstraram um desempenho melhor foi utilizada a ANOVA para medidas repetidas. Para analisar as diferenças gerais entre os grupos em um conjunto de variáveis dependentes (que constituem os tipos de habilidades de acordo com o teste M-ABC) e depois fragmentar as análises por variável dependente (destrezas manuais, equilíbrio e habilidades com bolas) foi utilizado a Análise Multivariada de Variância, assim como para verificar os efeitos interativos das variáveis de sexo e idade. Ambas as análises de variância foram feitas utilizando um modelo com duas variáveis independentes, sexo e faixa etária (2X2). Para todas as análises estatísticas foi adotado o nível de significância de 5%. Os resultados demonstraram que 10,8% das crianças foram indicadas com DCD e 12% apresentou risco de DCD. Os resultados indicam que as crianças apresentaram mais dificuldades motoras nas habilidades relacionadas às destrezas manuais. As análises revelaram uma diferença estatisticamente significativa entre os sexos e entre as idades. Ao analisar as variáveis dependentes individuais, separadas por meio da análise dos efeitos principais, pode-se observar que houve diferença estatisticamente significativa entre os sexos e as idades somente para as habilidades com bola. Estes resultados sugerem que os meninos tiveram o desempenho melhor nas habilidades com bola, assim como as crianças com 8 anos. A prevalência de crianças com DCD nas escolas municipais de Florianópolis SC Brasil, excedeu aos 4-6% de prevalência de DCD nas crianças de 5 a 11 anos apontado pela literatura. A identificação precoce de crianças com dificuldades motoras é essencial para o embasamento de estratégias de intervenção por profissionais da área.

The purpose of this paper is to study and describe Poland’s policy co-ordination system, demonstrate the decline in Polish administrative capacity over time, and attempt to find and explain institutionality- driven links between the two. For this purpose, three policy co-ordination systems were deconstructed, a mechanism for analysing that data created, and information on Poland’s administrative performance was collected. The study finds that some structural features within Poland’s hierarchical, amalgamated co-ordination system can foster incentives to suppress the improvement of its own public administration.

Wang Zengqi, an important representative of modern Chinese literature, is best known as an author of pastoral, nostalgic fiction, written in the early 1980s, and as Shen Congwen's student. His short stories ‚Ordination' (Shoujie 受戒) (1980) and "A Tale of Big Nur" (Danao jishi 大淖记事) (1981) are considered masterpieces, and stand as major steps in rebirth of New Era Chinese literature. The present paper introduces thematic and motivic analysis of Wang Zengqi's key short stories. Attention is also payed to the literary qualities and genre characteristics of his representative short stories and the development of author's literary style. Finally, the present paper discusses to what extent Wang Zengqi's work is influenced by his teacher, Shen Congwen. Keywords Wang Zengqi, Ordination (Shoujie 受戒), A Tale of Big Nur (Danao jishi 大淖记事), Shen Congwen, pastoral fiction

Most sport coaches are under the impression that if their athletes have 20/20 vision, nothing more is needed to be done in the visual arena. This is a common misconception in youth sport and professional sport. Every sport involves the visual system in one way or another, yet very few coaches or athletes spend any time training the visual system to perform optimally during competition. To perform at the highest level of competition, athletes have to be in tune with their visual motor and visual perceptual system. Participants consisted of 200 male and female recruits enrolled for Basic Military Training (BMT) at the training academy in Ellisras, South Africa. Only recruits who completed the informed consent and adhere to the inclusion exclusion criteria participated in the study. The primary purpose of this study was to see how the recruits improve their visual skills after intense training which included cardio-respiratory endurance, muscular strength (upper body and abdominal), muscular endurance, speed, power, agility and flexibility. The training intensity of the sessions exceeded 6 metabolic equivalents (METs). Data sampling was completed over a period of one week during weeks 1, 12 and 20. The proposed schedule for the data gathering is suggested to ensure the special requirements demanded by the different tests and to see at what rate their visual skill improve. Results in this study suggests that a Basic Military Training (BMT) programme, focusing on intense physical training, enhances hand-eye co-ordination, visual response speed, accuracy, anticipation, visual concentration and short term visual memory. The improvement of various visual skills observed in this research provides evidence that physical exercise, along with an enhanced state of physical fitness, does have a positive effect on visual proficiency. / Dissertation (MSc)--University of Pretoria, 2013. / gm2014 / Physiology / unrestricted

Wind turbine modelling using doubly-fed induction generators is a well-known subject. However, studies have tended to focus on optimising the components of the system rather than considering the interaction between the components. This research examines the interaction of the control methods for a doubly-fed induction generator (DFIG) in a wind turbine application integrating them with the crowbar protection control and DC-link brake control to make the best use of the converter. The controls of the rotor-side and the grid-side converters of the DFIG model are both well established and have been shown to work. Typically the crowbar protection is designed in order to protect the rotor-side converter and the power electronic components of the DFIG system from high currents occurring in the rotor due to the faults. The DC-link brake-overvoltage protection is also designed to prevent the overcharging of the DC-link capacitor placed between the rotor-side converter and the grid-side converter. In order to show that these protection schemes work and with thought can co-ordinate with each other, tests consisting of a number of balanced three-, two- and one-phase voltage sags are applied to the network voltage. The main contributions of this thesis are establishing operational tuning and design limits for the controllers and system subassemblies. This is to minimise the electrical subsystem interaction while maintaining adequate performance, and have an improved DC-link control. This work also includes a full electrical system study of the wind turbine and an essential literature review on significant references in the field of the DFIG wind turbine system modelling, control and protection. Specifically this research project makes a number of novel contributions to the literature: enhanced DC voltage control including operating point sensitivity analysis and dynamic stiffness assessment, sensitivity and robustness analyses of the power loop control and control loop segmentation by appropriately tuning the controller loops.

Using flake dimensions and attributes commonly agreed are associated with site use, occupation age, and occupation duration, it was argued that relative estimations of site function and occupation age could be determined using debitage. This is particularly beneficial for assemblages that have little to no diagnostics that could provide a general cultural period for one or more occupations at a site. The results of this study suggest that, although certain attributes are generally associated with lithic production stage, relative age, and duration indicators, they were not all applicable within this study. The methods employed were relatively successful; however, reducing the number of classes, removing of a dimension, and more sites that meet the definition of lithic scatter is needed. Furthermore, testing occupation duration using the number of breaks on a flake is not possible unless it is proven a single occupation site.

HEARING ALL THE DRUMS: TOWARDS A MORE INCLUSIVE CONGREGATION is about increasing the participation of women in positions of both leadership and church ministry praxis within the Seventh Day Adventist church in South Africa. Women have been excluded in the office of elder, and have been generally excluded from preaching during the worship hour. The research process followed a participatory way of doing research, while using theories on social construction and post-modernist epistemological approach. The theologies that inform this work are contextual in nature and include African and Feminist theologies. In the pursuit for change, however, care is maintained to use inclusive practices that attempt to avoid polarising the congregation and their concomitant theologies. / Practical Theology / M.Th.

This study considered indigenisation to involve a process of making the local people `feel at home' in their Church. The ministry of early catechists such as Bernard Mizeki and Frank Ziqubu was crucial in showing the fact that the Anglican Church was not necessarily a church for Europeans only, but for the indigenous people as well. After this first generation of catechists there were numerous indigenous catechists who also ministered in the Diocese of Mashonaland by way of preparing people for the different sacraments found in the Anglican Church. On the other hand the training of the indigenous people for the ordained ministry was also another significant step in the process of indigenisation in the Diocese of Mashonaland. In this regard theological institutions such as St Augustine's Seminary in Penhalonga Manicaland, St Peter's Seminary Rossettenville in Johannesburg and St John's Seminary in Lusaka provided the much needed training. This study also revealed that although the Diocese of Mashonaland had an indigenous person at its helm in 1981, it remained European in several facets of its life. Although translations as a form of indigenisation started from the beginning of the Diocese of Mashonaland and continued right up to 1981, it seems it actually crippled the local indigenous peoples' innovativeness and ingenuity. In addition indigenous musical instruments also took sometime before they could be accepted in divine worship. On the other hand local art and décor as well as local architectural expressions took time to be incorporated into the Diocese of Mashonaland. However few early European missionaries such as Arthur Shirley Cripps and Edgar Lloyd tried to implement local architecture and décor in their churches in Daramombe and Rusape respectively. This study has also established that although the Anglican Diocese of Mashonaland got indigenous leadership by 1981, its liturgy, theology as well as its Acts and Canons remained European. / Christian Spirituality, Church History and Missiology / D.
