As part of an on-going process of centralizing control of government science and technology (S&T) after World War II, in 1966 the Navy went through a major reorganization that was intended to centralize the strategic management of the Navy laboratory system. This centralization was to be accomplished by placing the major Navy research and development activities in a single systems command - the Naval Material Command - and establishing the position of Director of Navy Laboratories. Organizational studies and reorganizations continued for the next 25 years until the Naval Material Command and the Director of Navy Laboratories were disestablished in 1985 and 1991, respectively. This dissertation is, in part, an historical study of the Navy from 1946 to 1966 that focuses on the bureaus and laboratories. It summarizes the organizational changes related to strategic management and planning of science and technology. The 1966 reorganization was a critical event because it created the first formal Navy laboratory system. It is proposed that the 1966 reorganization was not successful in centralizing the strategic management of the Navy laboratory system. Classical organization theory offers an explanation of this failure. What can complexity theory add? The overarching contribution is in recognizing that a "Navy Laboratory System" existed before one was formally established in 1966. This argument is developed by considering two specific aspects of complexity theory. First, there is the notion that strategic management of the laboratory system resulted from the complex interactions of the smaller units that comprise the system (rather than the result of organization and process choices by senior leadership). Second, there is the theory that an organization will exhibit different behaviors at different times or in different parts of the organization at the same time. This translates into the idea that at particular times and places, the formal structure was dominant in strategic management, but at other times the "emergent" organization was dominant. In fact, if power law theory is applicable, then the periods of stability (where the formal structure was dominant) ought to be more prevalent than the turbulent periods where the emergent organization was dominant in strategic management. This case is made by describing agent-based models of the Navy laboratory system at two points in time and using them to identify the expected performance characteristics of the system. Historical and organizational artifacts are then used to make the case that the postulated system existed. / Ph. D.

The relationship between the organisation and its members is governed by what motivates them to work and the fulfilment they derive from it. The manager needs to know how best to elicit the co-operation of staff and direct their performance towards achieving the goals and objectives of the organisation. Managers need to understand the nature of human behaviour and how best to motivate staff so that they can work willingly and effectively. This study was conducted at the KwaZulu-Natal Police Forensic Science Laboratory (FSL-KZN). The aim of the study was to evaluate and investigate the status of employee motivation within this environment. The objectives of this study were to investigate the effect and influence of employee recognition, communication processes and social interaction on employee motivation. The relationship between the organisational reward systems and employee motivation was also investigated as well as identifying current motivating and de-motivating factors. The quantitative method was used for this study. Information was gathered from the sample which comprised of employees from all levels of the KwaZulu-Natal Police Forensic Science Laboratory (FSL-KZN). The population for this study was 163 FSL-KZN employees, of which 79 actually completed and returned the questionnaires (n=79). The research instrument (questionnaire) comprised 3 demographic questions, 22 closed ended likert scale type questions and 3 open ended questions. The simple random sampling technique was employed in this study which was then statistically analysed using the Statistical Package for the Social Sciences (SPSS) programme. The key statistical findings of the study were the organisation needs to urgently improve its career ‘pathing’ strategy and a significant percentage cited an improvement was urgently needed in terms of communication and social aspects within the organisation. A fair percentage also recommended improved financial rewards and incentive programmes as the general consensus was that management fails to effectively recognise employee contribution and input to the organisation and most employees are of the view that they are not suitably rewarded for their efforts. Though the study was too small for the results to be generalized to other forensic science laboratories, the recommendations made will certainly address current and pertinent issues at the KwaZulu-Natal Police Forensic Science Laboratory. / Thesis (MBA)-University of KwaZulu-Natal, Durban, 2013.

Science education should teach students to critically evaluate new information. Students have difficulties making connections among graphs of variables, physical concepts and the real world and often perceive graphs as a picture. Calculator Based Laboratories (CBL) provide immediately available calculator drawn graphics of objects in motion. Up to date effectiveness of microcomputers are evaluated but there are few studies on the use of CBL, which are feasible, easy to use, portable and cheap with respect to microcomputers. In this study we want to find out the effectiveness of CBL method on the graphical interpretation of kinematical concepts in physics at METU teacher candidates. Data will be analyzed with SPSS for Windows program. The study carried out 2002 &ndash / 2003 Spring Semester at Education Faculty in METU. 32 students from two classes were involved in the study. All students administered TUG-K (Test of Understanding Graphs &ndash / Kinematics) before and after the CBL activities. The data obtained from the administration of the pretests and the posttest were analyzed statistical technique of Paired Samples T Test. The statistical analysis failed to show any significant difference in the students&rsquo / understandings of kinematics graphs.

Mandated accreditation of crime laboratories is a fairly new phenomenon. The state of Texas was the first to require that crime laboratories be accredited in order to be able to present evidence in a criminal proceeding. The laws that govern this are Texas House Bill 2703 and Texas House Bill 1068. The goal of this study is see how the enactment of these laws impacted crime laboratories. There are 42 crime laboratories that are accredited in the state of Texas. This study was conducted by the use of telephone survey interviews. Results indicated that mandated accreditation is a step in the right direction to ensure that objectivity is maintained during the processing and evaluation of physical evidence.

This study has a twofold purpose in that it attempts to identify how knowledgeable investigators are about the collection and use of DNA in relation to the building of a criminal case, and to establish how optimally DNA as evidence is utilised. The study has revealed several shortcomings which render the use of DNA evidence inadmissible in criminal proceedings. The researcher also analysed other aspects relating to DNA evidence, namely: identification, individualisation, criminal investigation, forensic investigation, and objectives of criminal investigation. For criminal investigators to be successful in their investigation of cases involving DNA, it is imperative for them to have a clear understanding of the basic concepts surrounding DNA investigations and the value of DNA evidence. It is submitted that, because of a lack of knowledge in DNA-related investigations by detectives, a lack of training in DNA-related cases and delays in the collection of DNA evidence, valuable evidence is often lost and/or contaminated. This causes such evidence to become inadmissible in criminal proceedings, and has a negative impact on the conviction rate for such crimes. / Preface in English and Afrikaans / Hierdie studie het ’n tweevoudige doel in die poging om te identifiseer hoe kundig ondersoekers is aangaande die insameling en gebruik van DNA in terme van die bou van ’n kriminele saak en die vasstel van hoe DNA optimal [sic] as bewys gebruik kan word. Die studie het getoon dat daar verskeie tekortkominge is wat teweeg gebring het dat die gebruik van DNA bewys onaanvaarbaar was in kriminele prosedure. Die navorser het ook ander aspekte geanaliseer aangaande DNA bewyse, naamlik: identifikasie, individualisering van onderwerpe tydens ondersoek, kriminele ondersoek, forensiese ondersoek, en die aspekte van kri-minele ondersoeke. Vir die kriminele ondersoekers om suksesvol te wees in hulle ondersoek van sake waarby DNA betrokke is, is dit vir hulle van kardinale belang om ’n suiwere begrip van die basiese konsep rondom DNA ondersoeke en die waarde van DNA bewyse te hê. Dit is voortgebring dat, as gevolg van die tekort aan kennis in DNA ondersoeke, asook opleiding van DNA-sake by die speurders, en vertraging in die versameling van DNA bewysstukke, waardevolle bewyse is telkens verlore of gekontamineer. Dit veroorsaak dat sulke bewyse verwerp word in kriminele prosesse, en het ’n negatiewe impak op die vonnis statestieke [sic] vir sulke misdade. / Criminology / M.Tech. (Forensic Investigation)
