In spite of the SAPS having a dedicated polygraph capacity since 1998, little research has been conducted with regard to the use of the polygraph in criminal investigations. Consequently, the aim of this research was to focus on the perceptions and experiences of investigators in the SAPS regarding the application of polygraph testing in criminal investigations, the application of the polygraph as an investigative aid, the extent to which it is used by SAPS investigators to resolve criminal cases opened by the general public and/or in internal departmental criminal investigations; and whether or not it has helped to solve cases by giving direction and/or focus to the investigator when an investigation is at an impasse. A qualitative research approach was conducted among investigators within the SAPS. The research design selected for this study was grounded theory. The sample consisted of twenty investigators, ten of whom had previously used polygraph examinations in their investigations and ten of whom had not. Data was collected from interviews, document analysis, field notes and memoranda which presented and detailed the perceptions and experiences of investigators in the SAPS regarding the application of polygraph tests in criminal investigations. / Criminology and Security Science / M.A. (Criminology)

This diploma thesis deals with methods used to determine the temperature field distribution within an electric machine. The first part is focused on methods of temperature measurement, generation and transfer of the thermal energy within the electric machine, asynchronous motor in particular. The thesis describes classical methods of temperature measurement and it also deals with ANSYS Workbench finite element method for thermal analysis of the motor. The final part of the thesis is focused on a comparation of all discussed methods with respect to results of thermal test for real asynchronous motor and concludes the most proper method.

The goal of this master´s thesis is to design load bearing structure of a sports hall. The thesis is elaborated in two variants of the structure design of the sports hall for common types of sports (handball, footsal, tennis, volleyball, basketball). The ground plan dimension is 42 to 72 meters and the construction height is 8 meters. The construction is designed for the district of Brno city. In the structural anlysis there were the following main load bearing structural elements designed and examined: glue laminated timber truss, wood purlins, steel beams, rods and bracing, columns, which together with the transverse girders are linked and foot and anchoring. The selected variant is also further developed. Part of the work is drawing documentation of the choosen variant, disposition drawing and drawings of the selected details.

The diploma thesis deals with the passport of family houses and its creation. The first part describes the building condition survey from a theoretical point of view, its advantages, purposes and sorting, possible owners and so its legislative background. Thereafter it describes in detail the procedure of making the passport and applies the procedure on a particular family house in Brno. Medium passport of the family house focuses on describing the structural and technical condition. It also describes the current faults, errors and methods whose reveals them. Subsequently, the proposals for solution of these adjustments follows together with the resolution of emergency in specific cases.

The diploma thesis in theoretical section is focused on a brief overview of the methods used in the diagnostic of reinforced concrete structures. The practical part of this thesis deals with the diagnostics of the manufacturing reinforced concrete buildings in the complex Fatra Napajedla. This part will provide concrete strength of existing structures and will verify the reinforcement of individual elements of the structure by means of modern devices – radar and electromagnetic rebar locator. In the final section of this thesis will be performed static reports of selected parts of the structure.

Les travaux réalisés dans cette thèse proposent une aide à la décision pour améliorer la qualité de l’apprentissage. L’apprentissage scolaire englobe deux dimension; une dimension humaine et une dimension pédagogique. La dimension humaine inclut l’apprenant et l’enseignant. La dimension pédagogique, représentée par le programme fixé par l’établissement éducatif, correspond au savoir. Ce dernier va se transformer en connaissance chez l’apprenant. Les deux notions de connaissance et savoir sont donc tout à fait différentes. La distance entre les deux représente la distance entre ce que l’enseignant présente (le savoir) et ce que l’apprenant acquière (la connaissance). La qualité de l’apprentissage concerne les apprenants qui vont à l’école pour acquérir le savoir. En fait, apprendre consiste à intérioriser le savoir. Cette intériorisation demande des efforts pour un changement intellectuel persévérant et exige une continuité basée sur les expériences antérieures. L’acquisition du savoir et sa transformation en connaissance par l’apprenant sont influencées par plusieurs facteurs qui interviennent positivement ou négativement sur la quantité et la qualité de cette connaissance. Il peut résider chez l’apprenant une confusion entre les deux notions qui peut l’amener à valoriser ou ignorer sa connaissance. Le processus de construction des connaissances par le savoir diffusé exige une constante mise en œuvre de procédures d’évaluation. Le processus d’évaluation apprécie alors la structure de la connaissance pour prendre des décisions destinées à la faire évoluer. Cependant, lors d’une évaluation, la confusion entre connaissance et savoir peut amener l’apprenant à valoriser le score, négligeant ainsi le regard qu’il pourrait porter sur les processus de transformation des connaissances au profit d’une restitution la plus fidèle possible du savoir. Cette confusion peut être mise en évidence pourvu que l’évaluation intègre une dimension processuelle. Dès lors, l’évaluation peut être mieux associée à des actions d’amélioration et de transformation des connaissances. L’évaluation peut alors être abordée dans une logique d’aide à la décision. Dans ce travail nous montrerons donc qu’une situation d’apprentissage s’apparente à une situation d’aide à la décision. / The research realized in this thesis proposes a decision support to improve the quality of learning. The learning includes two dimensions; human dimension and pedagogic one. The human dimension includes the learner and the teacher. The pedagogic dimension represented in curriculum set by the educational establishment; it is the know. The learner is going to transform the know into knowledge. Thus the know and the knowledge are two notions completely different. The distance between both is the distance between what the teacher presents (the know) and what the learner acquires (the knowledge). The quality of the learning concerns the learners who go to the school to acquire the know. In fact, learning consists in interiorizing the know. This internalization requires the efforts for persistent intellectual change and demands continuity based on past experiences. The acquisition of knowledge and its transformation into knowledge by the learner is influenced by several factors that affect positively or negatively on the quantity and quality of this knowledge. The confusion between the know and the knowledge guide the learner to value or to ignore his knowledge. The knowledge construction process by the diffused know requires an constant evaluation process. The process of evaluation then appreciates the structure of knowledge to make decisions intended to make it evolve. However, during an evaluation, the confusion between knowledge and knowledge can bring learner to value the score so neglecting the importance which he must give for the transformation knowledge process in favor of the highest possible fidelity of knowledge. This confusion can be detected provided that the evaluation includes a processual dimension. Therefore, the evaluation may be better associated with improvement actions and transformation of knowledge. Then the evaluation can be addressed in a logical decision support. Therefore In this research we demonstrate that the learning situation is a decision aiding situation.

Im Jahr 2009 sind die deutschen Hochschulen für beruflich qualifizierte Bewerber ohne schulische Hochschulzugangsberechtigung geöffnet worden. Der Beitrag fragt, inwiefern sich diese nicht-traditionellen Studierenden hinsichtlich des Studienerfolgs von traditionellen Studierenden mit Abitur unterscheiden. Auf der Basis von Überlegungen zu Kompetenzunterschieden aufgrund unterschiedlicher Bildungsverläufe und der kulturellen Schließung des akademischen Feldes für Personen mit niedrigerer sozialer Herkunft bilden wir Hypothesen zu Leistungsunterschieden. Diese überprüfen wir anhand von Studien- und Prüfungsleistungsdaten von 4.224 B.A.-Studierenden eines Fachbereichs einer deutschen Universität. Die Analysen zeigen, dass nicht-traditionelle Studierende im Vergleich zu Personen mit Abitur im ersten Studienjahr 7,4 Prozent weniger Lehrveranstaltungen bestehen, eine um ein Fünftel geringere Wahrscheinlichkeit aufweisen, das Studium innerhalb eines Zeitraums von mindestens neun Semestern zu beenden und das Studium mit einem durchschnittlich um 0,15 Notenpunkte schlechteren Endergebnis abschließen. Aufgrund der spezifischen Bedingungen des analysierten Fachbereichs schlussfolgern wir, dass diese Leistungsunterschiede in der Breite der deutschen Hochschullandschaft stärker ausgeprägt sein müssten als in dem untersuchten spezifischen Fall.

Objective: The aim of this study was to develop, evaluate, and standardize a short form of the well-established Eating Disorder Examination-Questionnaire (EDE-Q). The newly developed EDE-Q8 was required to reflect the originally postulated structure of the EDE-Q. Method: Data were drawn from two nationwide representative population surveys in Germany: a survey conducted to develop the EDE-Q8 in 2009 (N = 2520); and a survey conducted in 2013 (N = 2508) for the evaluation and calculation of EDE-Q8 percentiles. Results: The EDE-Q8 had excellent item characteristics, very good reliability and a very good model fit for the postulated second-order factorial structure. Furthermore, a strong correlation between the EDE-Q8 and a 13 item short form of the Eating Attitudes Test was observed. Discussion: The EDE-Q8 appears to be particularly suitable in epidemiological research, when an economical assessment of global eating disorder psychopathology is required.
