Evaluating the use of CCTV surveillance systems for crime control and prevention : selected case studies from Johannesburg and Tshwane, Gauteng

Moyo, Sheperd 16 January 2020 (has links)
This research evaluates crime prevention effects/impact of open-street closed circuit television (CCTV) surveillance systems as installed in the selected areas (research sites) of the cities of Johannesburg and Tshwane in the Gauteng Province of South Africa on crimes occurring in these surveilled areas. Currently, CCTV surveillance systems are a common sight in many of the urban areas of South Africa.The principal aim of this study was to explore the evaluation of CCTV for crime prevention, reduction and control. The results show that, despite a lack of empirical evidence as to the value of CCTV surveillance systems in preventing or reducing crime, there is strong public support for these systems and that the foundation for much of this support lies in the perceptions/feelings of members of the public of greater safety generated in areas with CCTV coverage. The method of sampling used was a purposive non-probability sampling approach. Participants were selected for interviews based on their knowledge and experience of CCTV systems. The results show that, despite this lack of empirical evidence, CCTV appears to be a viable option for crime prevention and control when integrated with evidence-based strategies rather than as a stand-alone tactic in order to achieve crime control benefits. / Criminology and Security Science / M.

Sledování zaměstnanců / Monitoring of Employees

Losenický, Martin January 2019 (has links)
Monitoring of Employees Abstract The thesis aims to provide a critical review of the complex topic of employees monitoring to the reader. The thesis summarises the information from the le- gislation connected to employees monitoring concerning the legal aspects of per- sonal data protection. The thesis also takes into account the recent changes in European legislation. The primary legislation related to this subject is the pro- vision of Section 316 of the labour code, as well as the European regulation of personal data protection GDPR. The thesis is divided into four chapters. The first chapter offers a historical overview of the labour law and the protection of privacy and personal data. In the second chapter, the particular legal bases of employees monitoring are analysed. The third part is focused on the history and the activity of the supervisory authorities which are the Office for Perso- nal Data Protection and the State Labour Inspection Office. In the last chapter, the particular methods of employees monitoring, namely closed-circuit television, control of correspondence, phone calls and business computers, location tracking and biometric identification are described and analysed. Keywords Employees monitoring, closed-circuit television, GDPR

Longitudinal impact of newly acquired closed-circuit televisions (CCTV) on quality of life for low vision patients

Huber, Jessica January 2007 (has links)
Ongoing efforts to quantify changes in quality of life attributable to low vision rehabilitation have focused on the utility of a single test instrument to measure this multidimensional concept. It is hypothesized that quality of life is best assessed using multiple instruments to capture some of its component facets, including functional status and psychosocial impact. Low vision devices have a predictably spontaneous impact on functional vision status, but associated psychosocial impact occurs with different magnitudes and over more protracted time intervals. The National Eye Institute Visual Function Questionnaire (NEI VFQ-25) measures the functional status of individuals in key vision areas that are associated with quality of life. The Psychosocial Impact of Assistive Devices Scale (PIADS) is an instrument that measures the psychosocial impact of assistive device intervention in three quality of life domains: competence, adaptability, and self-esteem. 68 participants were obtained from an ongoing parent study. These participants were recruited through the Low Vision Clinic at the University of Waterloo. They had a primary diagnosis of age-related macular degeneration (ARMD) and were obtaining a CCTV system for the first time. Assessments from the parent study used in this thesis included follow-up from 2 weeks, 1 month, 3 months, and 6 months post-adoption of the CCTV. The two tests administered were to measure functional vision status (NEI VFQ-25) and perceived psychosocial impact (PIADS), according the framework outlined by the Consortium for Assistive Technology Outcomes Research (CATOR). Multivariate repeated-measures ANVOA results confirmed that CCTV systems have an immediate and robust effect on the daily visual functioning of their users, and that this effect is stable over long periods of device use. The psychosocial impact of CCTV device use peaks in the shorter term and then seems to wane in the longer term for reasons that are not yet understood. The NEI VFQ-25 and the PIADS appear to have differential sensitivity to important influences on low vision rehabilitation outcomes. This project has demonstrated the value of longitudinal outcomes research in low vision rehabilitation. After obtaining a CCTV, visual function status remains static while psychosocial impact is dynamic during 6-months of follow-up.
