This thesis deals with efficiency of government expenditures to the non-profit sector. As a subject of probing will be used Czech scouting organization: Junák -- svaz skautů a skautek ČR. This thesis asks whether the government expenditures to Junák constitute costs, or are a certain form of investment. Author use short historical analysis, analysis of incomes and expenditures of Junák, valuation of volunteer work hour and social capital which is related to scouting.

This thesis focuses on setting the range and efficiency of a water ram pump through experimental measurements in a laboratory. The measurements were carried out on three different constructions of water ram pump, each of the designed and assembled by the author of this thesis himself, to find out whether the weight on the pulsating valve has an influence on the water ram pump efficiency. Further on this thesis aims at the comparison of up to now methods of water transport arrangement used at a summer camp and the usage of the water ram pump and its advantages. The principal of water ram pump originates in hydraulic impact that is being precisely described in a great detail as well. On of the chapters even includes the placement manual for the water ram pump and its overall assembly and connexion. Because the presence of floating debris is inevitable, this thesis also deals with the possibility to solve the incoming water impurities by adding an inflow gating to prevent such problem. This inflow gating has only been designed in a Flow 3D programme to introduce the idea and functions.

Herbicides applications could possibly be reduced if targeted. Targeting the applications requires prior identification and quantification of the weed population. This task could possibly be done by a weed scout robot. The ability to position a camera over the inter-row space of densely seeded crops will help to simplify the task of automatically quantifying weed infestations. As part of the development of an autonomous weed scout, a vision-based local positioning system for weed detection has been developed and tested in a laboratory setting. Four Line-detection algorithms have been tested and a robotic positioning device, or XYZtheta-table, was developed and tested. <p> The Line-detection algorithms were based respectively on a stripe analysis, a blob analysis, a linear regression and the Hough Transform. The last two also included an edge-detection step. Images of parallel line patterns representing crop rows were collected at different angles, with and without weed-simulating noise. The images were processed by the four programs. The ability of the programs to determine the angle of the rows and the location of an inter-row space centreline was evaluated in a laboratory setting. All algorithms behaved approximately the same when determining the rows angle in the noise-free images, with a mean error of 0.5°. In the same situation, all algorithms could find the centreline of an inter-row space within 2.7 mm. Generally, the mean errors increased when noise was added to the images, up to 1.1° and 8.5 mm for the Linear Regression algorithm. Specific dispersions of the weeds were identified as possible causes of increase of the error in noisy images. Because of its insensitivity to noise, the Stripe Analysis algorithm was considered the best overall. The fastest program was the Blob Analysis algorithm with a mean processing time of 0.35 s per image. Future work involves evaluation of the Line-detection algorithms with field images. <p>The XYZtheta-table consisted of rails allowing movement of a camera in the 3 orthogonal directions and of a rotational table that could rotate the camera about a vertical axis. The ability of the XYZtheta-table to accurately move the camera within the XY-space and rotate it at a desired angle was evaluated in a laboratory setting. The XYZtheta-table was able to move the camera within 7 mm of a target and to rotate it with a mean error of 0.07°. The positioning accuracy could be improved by simple mechanical modifications on the XYZtheta-table.

Labor shortage has prompted researchers to develop robot platforms for agriculture field scouting tasks. Sensor-based automatic topographic mapping and scouting algorithms for rough and large unstructured environments were presented. It involves moving an image sensor to collect terrain and other information and concomitantly construct a terrain map in the working field. In this work, a triangular mesh map was first used to represent the rough field surface and plan exploring strategies. A 3D image sensor model was used to simulate collection of field elevation information.<p>A two-stage exploring policy was used to plan the next best viewpoint by considering both the distance and elevation change in the cost function. A greedy exploration algorithm based on the energy cost function was developed; the energy cost function not only considers the traveling distance, but also includes energy required to change elevation and the rolling resistance of the terrain. An information-based exploration policy was developed to choose the next best viewpoint to maximise the information gain and minimize the energy consumption. In a partially known environment, the information gain was estimated by applying the ray tracing algorithm. The two-part scouting algorithm was developed to address the field sampling problem; the coverage algorithm identifies a reasonable coverage path to traverse sampling points, while the dynamic path planning algorithm determines an optimal path between two adjacent sampling points.<p>The developed algorithms were validated in two agricultural fields and three virtual fields by simulation. Greedy exploration policy, based on energy consumption outperformed other pattern methods in energy, time, and travel distance in the first 80% of the exploration task. The exploration strategy, which incorporated the energy consumption and the information gain with a ray tracing algorithm using a coarse map, showed an advantage over other policies in terms of the total energy consumption and the path length by at least 6%. For scouting algorithms, line sweeping methods require less energy and a shorter distance than the potential function method.

La Fédération des scouts catholiques de la province de Québec fut fondée en 1935. Elle possédait un objectif exigeant : former des hommes, des chrétiens et des citoyens. Plus encore, elle se proposait de former des chefs aptes à influencer la société canadienne-française. Bien que chapeauté par l’Église catholique, le mouvement scout laissait aux laïcs une place prépondérante. Le scoutmestre (SM) et le chef de patrouille (CP) étaient les deux principaux chefs laïcs de la troupe scoute. Ils étaient respectivement en charge de la troupe (24 à 32 jeunes) et de la patrouille (6 à 8 jeunes). Le CP était lui-même un jeune scout. Par eux transitaient les idéaux et les systèmes de représentation inculqués aux jeunes. Ils devaient être formés adéquatement pour leur charge. Plus que de simples compétences de meneur, leur formation visait à leur transmettre un véritable rapport au monde : l’idéal du chef scout. Ce mémoire examine la méthode scoute prônée par la Fédération, tout en la nuançant avec le vécu de chefs et de jeunes scouts dans quatre troupes outremontaises. L’effet de la Révolution tranquille sur la représentation traditionnelle du chef scoute sera aussi abordé. / The Quebec Federation of catholic scouts was founded in 1935. Its goals were demanding: it proposed to train men, Christians and citizens. Moreover, it intended to train leaders who could influence the French-Canadian society. Although headed by the Catholic Church, the Francophone Quebec scout movement was in fact dominated and directed by laymen. The Scoutmaster (SM) and the Patrol Leader (PL) were the two main lay leaders of the scout troop. They were respectively in charge of the troop (24-32 youths) and the patrol (6-8 youths). The PL was a young scout himself. The ideals and system representations conveyed to youths were transmitted through the SM and PL. They needed to be trained appropriately to respect their commitment. Beyond the regular competencies of a leader, their training proposed to transmit nothing less than an authentic dealing with the world: the ideal of Scoutmaster. Taking the scout method recommended by the Federation as a formal background, this dissertation analyses its true life actualization by Scoutmasters and Patrol Leaders of four Outremont troops. The impact of the Quiet Revolution on the traditional representation of the boyscout leader is also examined.

Resistance development and possible non–target effects have been of concern since the first deployment of genetically modified crops with insecticidal properties. It is especially at the third trophic level and with important predators such as lacewings (Chrysoperla spp.) (Neuroptera: Chrysopidae) where negative effects of Cry 1Ab protein could have adverse effects in agro–ecosystems. Monitoring of the effect of genetically modified Bt maize on non–target organisms is required by law in South–Africa. Neuroptera are excellent indicators of environmental and habitat transformation, and also include key species for signifying areas and faunas that require priority protection. Monitoring techniques, especially for insect eggs, are often labour intensive and time consuming. A study was conducted to determine the preferred oviposition site of Chrysoperla spp. on maize plants to facilitate time–effective searching for eggs of these beneficial insects. Furthermore we determined if the presence of aphids on plants influenced Chrysoperla spp. oviposition preference. Another study was conducted to evaluate the effect of indirect exposure of C. pudica to Cry 1Ab protein, through healthy Bt–maize feeding prey, on its biology. Daily flight activity patterns and the height at which chrysopid adults fly above the crop canopy were also determined, as well as the movement of adult Chrysoperla spp. between maize fields and adjacent headlands. A clear spatial oviposition pattern was observed on maize plants and oviposition was not random as reported in earlier studies. This data facilitates rapid monitoring of the presence of eggs in maize cropping systems and is also of use in general pest management. Choicetest data showed that females responded positively to host plants that were infested with aphids. Feeding studies in which C. pudica larvae were indirectly exposed to Bt–toxin at the 3rd trophic level, showed a limited effect of Bt–toxin on only a few of the parameters that were evaluated. The pupal period and percentage adult emergence of larvae exposed to an unusually high amount of Bt–toxin was significantly shorter and lower respectively than that of the control group. The overall result of this study, in which the possible effect of food quality (prey) was excluded, showed that Cry 1Ab protein had an adverse affect only on certain fitness components during the life cycle of C. pudica. However, since this study represented a worst–case scenario where diverse prey was not available to C. pudica, negligible effects is expected under field conditions where prey is more diverse. It was determined that chrysopids was most active between 16:00 – 23:00 and that they fly largely between 0.5 m – 2.5 m above ground level. An attempt was also made to quantify migration between different vegetations types. This part was terminated because of bad weather conditions at several occasions when the experiment was attempted. Chrysopids were never present in grassland vegetation, but an adjacent lucerne field maintained a large population. As the maize crop developed chrysopid population numbers increased inside the field, presumably originating from the lucerne field. / Thesis (M.Sc (Environmental Science))--North-West University, Potchefstroom Campus, 2011.

This master thesis focuses on founding and forming of czech scouting. The main source are printed documents because of lack preserved archive documents. The main method is textological and comparative analysis. At first the history of world and czech scouting is presentend. To find out the essential differences between english and czech scouting I compared two basic manuals: Scouting for Boys and Základy junáctví. In the following part of the thesis I determine three areas in which the reception of scouting in czech environment is investigated. These areas are scout value system, attitude to nation and state and relation to the Sokol organisation. In thesis are also analyzed the results of international research concerning the origin of scouting in other european countries. The results are then copared with the situation in czech lands. The thesis also includes three following attachments: set of short biographies of mentioned personalities, edition of scout laws and filled research questionnaires.
