The pace at which data and information transfer and storage has shifted from PCs to mobile devices is of great concern to the digital forensics community. Android is fast becoming the operating system of choice for these hand-held devices, hence the need to develop better forensic techniques for data recovery cannot be over-emphasized. This thesis analyzes the volatile memory for Motorola Android devices with a shift from traditional physical memory extraction to carving residues of data on a “per process basis”. Each Android application runs in a separate process within its own Dalvik Virtual Machine (JVM) instance, thus, the proposed “per process basis” approach. To extract messages, we first extract the runtime memory of the MotoBlur application, then carve and reconstruct both deleted and undeleted messages (emails and chat messages). An experimental study covering two Android phones is also presented.

This thesis takes an interdisciplinary approach to the study of the impact that constructions of meaning and personal identity have upon the processes of professional decision-making, in the delivery of community safety services. The research draws upon the previous work undertaken in the fields of psychology, sociology, social anthropology, criminology and community safety. The research was composed of five separate studies. Study one was a Delphi exercise to determine consensus of meaning for different community terms in common usage for policy makers, practitioners and academics. The research was able to define consensual meanings for ten of the thirteen terms presented, including crime prevention, crime reduction and community safety. Consensus was not achieved for the terms community engagement, respect and quality of life and suggestions are made which may account for this result. Study two utilised repertory grids to investigate the ways that community safety professionals might construe the decisions that they have to make as part of their duties. Studies three and four utilised bespoke ISA/lpseus instruments, whose structures were informed by the results from Study Two. These instruments were used to further explore the construals and worldviews of a variety of community safety professionals through six process postulates. It was found that whilst an individual's initial job role or gender did not have significant impact upon their professional decision-making, the training that they had received in community safety and the time that they had spent working in the field did have a significant impact upon their professional decision-making. It was also found that the groups of community safety professionals differed in their attitudes towards those members of society who are the target of community safety activity. Study five involved the generation and piloting of a survey instrument whose various sections were designed to validate the findings generated from the previous studies, as well as providing further data on the decision-making processes of those working within community safety. The final chapter presents the Warren Person Process Priority (WaPPP) layered model of decision-making that was derived from the data collected to inform the current thesis. The outer Person layer is defined by the four-way typology derived from the Procedural / Free-form and Cautious / Adventurous bi-polar constructs of identity types that were identified from the ISA/lpseus studies. The middle layer of the model describes a number of different decision-making processes that professionals may follow when making a judgement or coming to a conclusion. The order of the processes was given by the results of the survey pilot. The central portion of the model presents a number of factors that may impact upon professional decision-making, determined from the ethnographic work that informed the ISA/lpseus studies. The order of these factors was determined from the preparatory data collection instrument that was used with the ISA/lpseus studies and confirmed by the results of the survey pilot. Suggestions are made for further research that may expand upon the results presented in this thesis. These include a larger version of the Delphi, with an international panel of experts; correlation of the ISA/lpseus instruments with other validated instruments for the measurement of personality, identity and decision-making and an expansion of the survey pilot.

This thesis aimed to assess the level of processes occurring in the selected company using the methods of process management and propose any changes. Selected company is the joint stock company SAG. In the theoretical part, the author defined the basic concepts and methods of process management, the output of the literature review. In the practical part, the analysis and evaluation processes in selected companies to identify those business processes that have priority in terms of their performance. Based on the priority business processes, subprocesses have been designed with low performance affecting a large number of critical factors, which were proposed changes to increase efficiency of these subprocesses.
