The purpose of the present study is to compare ability estimations obtained from computerized adaptive testing (CAT) procedure with the paper and pencil test administration results of Student Selection Examination (SSE) science subtest considering different ability estimation methods and test termination rules. There are two phases in the present study. In the first phase, a post-hoc simulation was conducted to find out relationships between examinee ability levels estimated by CAT and paper and pencil test versions of the SSE. Maximum Likelihood Estimation and Expected A Posteriori were used as ability estimation method. Test termination rules were standard error threshold and fixed number of items. Second phase was actualized by implementing a CAT administration to a group of examinees to investigate performance of CAT administration in an environment other than simulated administration. Findings of post-hoc simulations indicated CAT could be implemented by using Expected A Posteriori estimation method with standard error threshold value of 0.30 or higher for SSE. Correlation between ability estimates obtained by CAT and real SSE was found to be 0.95. Mean of number of items given to examinees by CAT is 18.4. Correlation between live CAT and real SSE ability estimations was 0.74. Number of items used for CAT administration is approximately 50% of the items in paper and pencil SSE science subtest. Results indicated that CAT for SSE science subtest provided ability estimations with higher reliability with fewer items compared to paper and pencil format.

The theoretical part concerns with the issues of managing human resources, the methods of selection of the new employees, as well as trends in human resources management and also by modern recruitment, the social networks. The application part consists of several sections. At the beginning of this part the chosen company is described, then an internal system of selection and recruitment with a questionnaire survey in Dura Automotive, which were attended by technical and economic employees from various departments. Furthermore, a statistical analysis of the data was carried out when it was investigated whether there is a verifiable relation between two attributes from the questionnaire survey. Based on the results of the questionnaire survey were made several suggestions, which could improve an efficiency of the analyzed processes.

The work attends to the process of admission of new staff, variety of methods, mode of choosing and the steps of selection new staff. There is a chapter that deals with strategy and instruments of staff selection, especially CV and interview. The final chapter is dedicated to the question of discrimination in respect to staff selection.

This master's thesis is focused on the recruiting of new employees with the aid of assessment centre method into MOSER, a.s. company. The attention is located on the determination of the terms, the estimation of the specific positions through the project. The main aim was given on the realization of the assessment centre and especially to the proposals and benefits related to its implementation, which satisfies requirements of MOSER, a.s. company.

This diploma thesis focuses on the selection process of the enterprise information system in the enterprise. The general investment process and vendor selection process are described in the theoretical part. This part also includes the analysis of the specifics and differences of the selection process of the information system and recommended methodology for public tender. The optimized selection process of enterprise information system is designed on the basis of specialized literature and found deficiencies. The applicability of the proposed process in practice is assessed through comparison with a case study of a successful selection of an information system in the final part of the thesis. The design can be considered usable in practice according to the described transformation of the tender in the case study to the proposed process. The application of the thesis outputs brings reduction of the required effort and increases the success rate of the selection process of the enterprise information system.

Thesis (MScEng (Mechanical and Mechatronic Engineering))--University of Stellenbosch, 2008. / Low Cost Automation (LCA) is of immense importance to industry, and even more so for small scale industries. In implementing LCA determining cost effective and efficient actuator alternatives present challenges for design engineers. Most often decisions are experiential or entirely based on manufacturer recommendations. Experience based decisions are most often biased with respect to the engineers’ knowledge. Similarly, manufacturer recommendations are restricted to their own products and are as such also biased. Either way, sub-optimum drive alternatives may sometimes be chosen. This demonstrates the need for making better informed decisions based on more than experience and what is available for use. This thesis reports the development of an electric actuator selection procedure and aid for use in the early layout design phase. It provides readily accessible information on technically viable actuator options. Experiential knowledge of experts in the field, commercial information, as well as data obtained from experimentation was used in its development. Being orientated towards LCA, the procedure has been targeted at the application of electric motors and their associated control technologies but can be extended to hydraulic, pneumatic and other actuators. In achieving a wider applicability of the selection aid, a generic set of actuator properties descriptive of most actuators was formulated. An AC drives control evaluation was conducted for developing the selection procedure and aid. It provided a means to validate some selection aid rules associated with actuator controllability. Quantitative data on speed and positioning accuracies of common AC three phase motors and their associated inverter technologies were the targeted results of the experimentation.

Computerized adaptive testing (CAT) provides a highly efficient alternative to the paper-and-pencil test. By selecting items that match examinees’ ability levels, CAT not only can shorten test length and administration time but it can also increase measurement precision and reduce measurement error. In CAT, maximum information (MI) is the most widely used item selection procedure. However, the major challenge with MI is the attenuation paradox, which results because the MI algorithm may lead to the selection of items that are not well targeted at an examinee’s true ability level, resulting in more errors in subsequent ability estimates. The solution is to find an alternative item selection procedure or an appropriate ability estimation method. CAT studies have not investigated the association between these two components of a CAT system based on polytomous IRT models. The present study compared the performance of four item selection procedures (MI, MPWI, MEI, and MEPV) across four ability estimation methods (MLE, WLE, EAP-N, and EAP-PS) under the mixed-format CAT based on the generalized partial credit model (GPCM). The test-unit pool and generated responses were based on test-units calibrated from an operational national test that included both independent dichotomous items and testlets. Several test conditions were manipulated: the unconstrained CAT as well as the constrained CAT in which the CCAT was used as the content-balancing, and the progressive-restricted procedure with maximum exposure rate equal to 0.19 (PR19) served as the exposure control in this study. The performance of various CAT conditions was evaluated in terms of measurement precision, exposure control properties, and the extent of selected-test-unit overlap. Results suggested that all item selection procedures, regardless of ability estimation methods, performed equally well in all evaluation indices across two CAT conditions. The MEPV procedure, however, was favorable in terms of a slightly lower maximum exposure rate, better pool utilization, and reduced test and selected-test-unit overlap than with the other three item selection procedures when both CCAT and PR19 procedures were implemented. It is not necessary to implement the sophisticated and computing-intensive Bayesian item selection procedures across ability estimation methods under the GPCM-based CAT. In terms of the ability estimation methods, MLE, WLE, and two EAP methods, regardless of item selection procedures, did not produce practical differences in all evaluation indices across two CAT conditions. The WLE method, however, generated significantly fewer non-convergent cases than did the MLE method. It was concluded that the WLE method, instead of MLE, should be considered, because the non-convergent case is less of an issue. The EAP estimation method, on the other hand, should be used with caution unless an appropriate prior θ distribution is specified. / text

Le régime d'autorisation est traditionnellement présenté comme un instrument depolice institué dans le but d'éviter que l'exercice de certaines libertés ne trouble l'ordre public. De cette fonction du régime d'autorisation se déduisent les principaux caractères de l'acte d'autorisation, acte unilatéral de police, précaire et incessible. Chacun de ces caractères se trouve cependant partiellement démenti par certaines évolutions du droit positif, en particulier par le phénomène de patrimonialisation qui touche un nombre croissant d'autorisations. Jusqu'à présent, ces évolutions n'ont été appréhendées que comme des exceptions à des principes dont la prétention à la généralité valait encore. L'ampleur de ces évolutions invite cependant à douter de la pérennité d'une telle présentation. L'objet de cette recherche est de montrer que ces évolutions sont la conséquence de ladiversité fonctionnelle du régime d'autorisation. En effet, le régime d'autorisation n'est pas nécessairement un instrument de police. Il est également utilisé comme un moyen soit de répartir l'accès à une ressource rare, soit d'organiser l'exercice d'une activité d'intérêt général. Cette diversité fonctionnelle du régime d'autorisation donne naissance à des catégories d'autorisations, catégories qui, une fois ordonnées, forment une typologie. Cette approche plurielle permet de comprendre pourquoi les autorisations répondent à des régimes juridiquesdifférents. / The authorisation scheme is traditionally presented as a policing system. From thisfunction of the authorisation scheme one can deduce the principal characteristics of the authorisation, unilateral police decision, precarious and untransferable. However, each of these characteristics is refuted by certain developments of substantive law, particularly by the phenomenon of patrimonialisation which affects an increasing number of authorisations. Until now, these developments have only been understood as exceptions to well-established principles. However, the scope of these developments casts doubt on the durability of such a way of seeing.The objective of this research is to show that these developments are the consequence of the functional diversity of the authorisation scheme. The authorisation scheme is not necessarily a policing system. It is also used as a means to allocate resources or to organise an activity of general interest. The functional diversity of the authorisation scheme gives rise to several categories of authorisations, categories that once organised form a typology. This pluralapproach makes it possible to understand why the authorisations operate under different legal frameworks.
