The goal of this thesis is an analysis of some aspects of the contracting entity profile, which we include in public procurement law. The first part is devoted to the development of the contracting authority profile from a historical perspective, from legislation Czechoslovak Republic until a valid and effective legislation, which is Act no. 134/2016 Coll., on public procurement, as well as an analysis of the concept contracting authority profile, it emerges from its legal definition. The second part, which can be described as its core, contains a progressive analysis of the various aspects of the contracting authority profile and its use as a legal institute in theory and practice. The thesis contains partial conclusions, references to the decisions and also the recommendations or proposals for legislation de lege ferenda.

The thesis aims at teaching various data structures algorithms using the Visualization Learning tool. The main objective of the work is to provide a learning opportunity for novice computer science students to gain a broader exposure towards data structure programming. The visualization learning tool is based on the Verification-Driven Learning model developed for software engineering. The tool serves as a platform for demonstrating visualizations of various data structures algorithms. All the visualizations are designed to emphasize the important operational features of various data structures. The learning tool encourages students into learning data structures by designing Learning Cases. The Learning Cases have been carefully designed to systematically implant bugs in a properly functioning visualization. Students are assigned the task of analyzing the code and also identify the bugs through quizzing. This provides students with a challenging hands-on learning experience that complements students’ textbook knowledge. It also serves as a significant foundation for pursuing future courses in data structures.

Thesis (M. Tech. (Food and Beverage Management, Dept. of Hospitality and Tourism)--Vaal University of Technology. / Objectives: The aim of this study was to develop and evaluate a nutrition education programme for Setlabotjha Primary School children in order to improve current knowledge. The study included all grade seven learners from two primary schools in one of the poorest areas in the Vaal Triangle. Children form Setlabojha Primary School formed the experimental group, while children from Ekujuleni Primary School formed the control group. Methods: The initial steps involved a baseline survey (Napier 2001 :78), which indicated that malnutrition exists at Setlaboljha Primary School. The baseline survey indicated stunting, wasting, underweight and poor food consumption patterns among the children. A literature survey was conducted, as a result of the findings of malnutrition, poverty and household food insecurity in Eatonside. Pre-tests were undertaken to determine current nutritional knowledge (for both groups) using a nutritional knowledge questionnaire developed by the Medical Research Council. The pre-tests results revealed poor nutritional knowledge and these results were used to develop the nutrition education tool (nutrition education playing cards) based on the South African Food Based Dietary Guidelines. The intervention, which involved the issuing, reading. playing and exchanging of the nutrition education playing cards had taken place over eleven weeks for the experimental group. The control group had received pamphlets and nutrition education lessons. After the intervention had taken place, post-tests were undertaken to compare the difference between the two groups and to determine the effectiveness of the nutrition education programme. Results: In general, the subjects of both groups had a good knowledge regarding sugar, water and salt consumption, as well as 'the key to a healthy way of eating'. Thus the inclusion of fruit and vegetables and variety were in the diet. Poor knowledge was evident in both groups pertaining to pregnancy, the importance of starch in the diet, alcohol consnmption, physical activity, vitamin A-rich foods and the inclusion of pilchards as a calcium-rich source. / NRF and Central Research Committee, VUT.

Thesis (M. Tech. - Dept. of Visual Arts and Design, Faculty of Human Sciences) / The aim of the study The aim of the study is to find an optimal research methodology that is both beneficial to qualitative researchers (regarding data quality and interviewee participation) and research participants (regarding enjoyment of the research process and means of expression). This takes the form of a comparison assessing the use of the visual method of photo-elicitation in qualitative interviews. Firstly, photo-elicitation interviews and standard qualitative interviews as two different methodologies are compared. In this study the research subjects are children, and as noted in Chapter 3, photo-elicitation is particularly applicable to young research subjects, as it tends to break down the communication barriers / SENEX

Automobile and aero industries have an increasing interestin materials with improved mechanical properties. However, manyof these new materials are classified as difficult-to-cut withconventional tools. It is obvious that tools, cutting processesand cutting models has to be devel-oped parallel to materialsscience. In this thesis rotary cutting tools are tested as analternative toexpensive diamond or cubic bore nitridetools. Metal matrix composites mostly consist of a light metalalloy (such as aluminium or titanium) reinforced with hard andabrasive ceramic parti-cles or fibres. On machining, thereinforcement results in a high rate of tool wear. This is themain problem for the machining of MMCs. Many factors affect thelife length of a tool, i.e. matrix alloy, type, size andfraction of the reinforcement, heat treatment, cuttingconditions and tool properties. In tests, the Al-SiC MMC formed a deformation layer duringmilling, probably affected by lack of cooling. The dominatingfactor for tool life was the cutting speed. Water jet or CO2cooling of turning did not provide dramatic increase in toollife. With PCD, cutting speeds up to 2000 m/min were usedwithout machining problems and BUE formation. Tool flank wearwas abrasive and crater wear created an "orange-peel type" wearsurface. PCD inserts did not show the typical increase in flankwear rate at the end of its lifetime. The use of self-propelled rotary tools seems to be apromising way to increase tool life. No BUE was formed on therotary tool at high cutting data. The measurements indicatethat the rotary tool creates twice as good surface as PCDtools. The longest tool life was gained with an inclinationangle of 10 degrees. Tool costs per component will beapproximately the same, but rotary cutting tool allows higherfeeds and therefore a higher production rate and thus a lowerproduction cost. The rotary cutting operation might have a potential toincrease productiv-ity in bar peeling. The lack of BUE withrotary cutting gives hope on higher tool life. The test resultsshow that tool wear was 27% lower with rotary cutting tools.Increase of cutting speed from 22 to 44 m/min did not affectcutting forces. This indicates that the cutting speed canincrease without significant change in tool wear rate. Issues related to rotary cutting like cutting models,cutting processes, standards, tools and models have beendiscussed. A tool wear model with kinetic energy has beendiscussed.

With a Categorizing tool for conservation of settlement remains we can, through better instructions, reduce the damages made to settlement remains in conjunction with forestmeasures.The purpose of this study was to create a categorizing tool for the conservation status of settlement remains. The categorization tool will be used to select specific remains for increased management. Interviews were conducted with the County administrative board in Östergötland, Board of Forestry (Skogsstyrelsen) and Holmen skog. Pre-field studies both with Skogsstyrelsen and Holmen skog were also conducted. A field study was conducted where totally 20 different areas of settlement remains were visited and used to create the tool. All settlement remains were located in Östergötland. The data collected showed that the largest amount of monuments were located close to a road and were relatively easy to access. The categorizing tool was made in collaboration with Holmen skog and was tested together with a representative from the company with the outcome as an approved categorizing tool for the demands of the company.

Brief, easy to use, psychometrically strong (i.e., pragmatic) instruments are needed to support implementation research; the current study assessed whether it was possible to develop a pragmatic observational treatment integrity instrument and reduce the amount of time coders spend making treatment integrity ratings (while maintaining score validity) of therapists delivering two protocols of individual cognitive-behavioral treatment (ICBT) for youth anxiety in research and practice settings. The 12-item instrument was derived from four observational treatment integrity instruments with promising score reliability and validity that assess adherence, competence, differentiation, and alliance. A sample of 106 youths (M age = 10.12, SD = 1.81, ages 7-14; 42.50% Female; 69.80% Caucasian) received one of three treatments to address anxiety: standard ICBT in a research setting (n = 51) or standard ICBT (n = 22), modular ICBT (n = 16), or usual care (UC; n = 17) in practice settings. Four coders independently coded five- and 15- minute segments sampled from four sessions from each client (N = 756 sessions). Ten percent of sessions were double-coded for reliability purposes. Reliability, sensitivity to change, construct validity, and predictive validity from the two segments were compared to full session treatment integrity scores independently archived in a study assessing the same clients. Across five- and 15-minute segments, the instrument produced promising score reliability and convergent validity evidence for adherence, competence, and alliance items (items intended for inclusion in ICBT for youth anxiety; M ICCs = .62, SD = .17; M rs = .58, SD = .12) and poor score reliability and validity evidence for differentiation items (items intended for inclusion in other treatment domains; M ICCs = .21, SD = .28; M rs = .27, SD = .25). This study met its primary aim, to develop an instrument that can be coded in less than 20 minutes while maintaining evidence of score validity. Researchers interested in developing such instruments can use this study design as a roadmap. Future research should investigate whether psychometric findings replicate across samples, why certain items (e.g., client-centered interventions) did not evidence score validity, and how this type of instrument can inform EBT training.

Syftet med vår studie är att genom fokusgruppsintervjuer belysa hur rektorer anser att de organiserar specialpedagogens uppdrag och hur denna organisering påverkar specialpedagogens funktion i skolan. Vi har valt att tillämpa ett organisationsteoretiskt perspektiv då vi menar att organiseringen av uppdraget är det som till största del påverkar arbetsuppgifterna. Särskilt fokus lägger vi på begreppen sensemaking och tool-dropping, vilka kort kan förklaras som att specialpedagogens funktion är meningsskapande för alla i verksamheten och hur verktyget specialpedagog kan och bör användas. Studien har relevans för det specialpedagogiska området då rektors kunskap om specialpedagogens kompetens har betydelse för vilka arbetsuppgifter specialpedagogen tilldelas. Vi har använt oss av en hermeneutisk ansats då vi tolkar rektorernas svar för att förstå hur de resonerar. Studiens empiriska material är insamlat med hjälp av fokusgruppsintervjuer. Resultatet visar att specialpedagogens uppdrag fortfarande är otydligt för såväl rektorer som för lärare, vilket påverkar både specialpedagogens mandat och arbetsuppgifter. Det framkommer också att i talet om specialpedagogens funktion i skolan är rektorerna överens och samstämmiga i vilka huvudsakliga arbetsuppgifter en specialpedagog ska ha, men att inte alla lyckas omvandla detta i praktiken. I diskussionen lyfter vi vikten av att rektorer skapar en genomarbetad och klart uttalad arbetsbeskrivning som är väl förankrad hos både specialpedagog och lärare, som ett led i att stärka och förtydliga specialpedagogens uppdrag på skolorna.

<div> <p>Fluorescent proteins and the biosensors created with them have been used extensively to monitor chemical species inside and outside of the cell. They have been used to increase our knowledge of cellular function in normal and diseased states. Fluorescent biosensors are advantageous because they can be genetically encoded, do not require exogenous reagents, and can be quantitative. Fluorescent biosensors are also able to measure analytes with high spatial and temporal resolutions, enabling measurements at the scale of physiological events. In this thesis efforts have made to increase the available fluorescent biosensor tools for imaging cellular events. This work includes creation of new sensors for two molecules not yet detectable via fluorescent protein biosensor, acetylcholine and adenosine diphosphate. Efforts were also made to improve the current available biosensors for adenosine triphosphate and cellular redox, to make them more compatible with multiplex and deep tissue imaging. Here I present my work to design, characterize and utilize these fluorescent biosensors.</p> </div> <br>
