Reducing Crime Affecting Urban Aboriginal People: The Potential for Effective Solutions in Winnipeg

Monchalin, Lisa A 18 January 2012 (has links)
This study examined the knowledge relevant to reducing crime affecting urban Aboriginal people through a risk-focused approach to prevention and a growing body of knowledge about how it gets implemented. It then examined this knowledge in a case study of its application in Winnipeg. Interviews were undertaken using a structured questionnaire with program stakeholders and policy planners involved in crime prevention initiatives, programming and policy in Winnipeg. Approximately half of the stakeholders were involved primarily with Aboriginal people and the other half were involved with programs that included both Aboriginal people and non-Aboriginal people. The interviews took place from September to November 2009. The interviews show that many stakeholders agree with the risk-focused prevention literature on risk factors and that there are prevention programs operating in Winnipeg serving at-risk Aboriginal people. Therefore, there exists the possibility of reducing crime given that they are tackling risk factors in a way which is consistent with crime prevention research. However, when the interviews turned to issues of implementation, it showed: • There is no responsibility centre to mobilize different sectors to tackle crime • Many programs are not implemented comprehensively • There is a lack of localized coordinated action (including support from the police chief and public engagement) • There is a lack of political leadership • There is no city-wide strategic plan, and • Programs are in constant competition for funding in order to continue operations. If we are to reduce the disproportionate rates of victimization and offending affecting urban Aboriginal peoples, we need to find more effective ways to implement the strategies that are proven to tackle risk factors. There must be support from the mayor and police chief, training and capacity development, and public engagement which fosters strong use of proven strategies. A responsibility centre with Aboriginal representation must be created. Funding must be expanded to support the community based organizations that are tackling established risk factors. Finally, sustained and adequate funding must be provided to these programs and the responsibility centre.

A high bit rate flexible MAC protocol for monitoring applications using 60ghz radio technology

Krishnan, Vikram 27 July 2010 (has links)
In recent years there has been a growing trend in optical wireless convergence. One particular aspect of this is 60 GHz radio-over-fiber technology. It is intended for use in wireless personal area networks. However, we think that the same technology could be used for monitoring applications in the indoor environment. It could be used to detect emergency situations or to detect intruders. We shall examine reasons why this choice might be a suitable one. We shall then propose a MAC layer protocol to accomplish this task. Since in case of emergency we might require to obtain data from only one node for an extended duration, flexibility in implementation is required. We shall develop an adaptive MAC protocol where this would be possible. We accomplish this by including two protocol modes called the Icarus mode, which is to be used in case of an emergency and the Resync mode which is used when normality is restored. A significant problem at high frequencies is that the beam becomes increasingly narrow and behaves more in a ray like condition. This implies that particularly in an indoor environment it is possible that the beam may be accidentally blocked. In this case the node must be able shift the beam in order to enable communication. We demonstrate three such strategies and offer a comparative analysis.

Preventing Youth Crime in Chongqing: The Implications of Western Scientific Evidence and Intergovernmental Guidelines on Crime Prevention Through Social Development

Cao, Jing 25 April 2012 (has links)
The primary objective of this thesis was to examine the relevance of intergovernmental decisions and western risk-focused social crime prevention to reducing youth crime within Chongqing, China. This involved a review of the existing literature that might be relevant to: (i) the current youth crime situation in the city of Chongqing, (ii) risk factors that might contribute to youth crime within Chongqing, (iii) the scientific evaluations of ‘evidence-based’ risk-focused crime prevention strategies for different age groups of youth, and (iv) implementation strategies for evidence-based innovations to reduce youth crime. Based on this knowledge, interviews with six key stakeholders of Chongqing were conducted for the purpose of obtaining initial perceptions regarding the utility and practicality of crime prevention through social development within Chongqing. Ultimately, this study demonstrates the preliminary relevance of western studies and action, recalls China’s endorsement of intergovernmental recommendations, and provides a foundation for further research.

Initial and repeated burglary victimisation : victim vulnerability, same offender involvement and implications for theory and crime prevention

Morgan, Frank January 2007 (has links)
[Truncated abstract] This thesis examines the phenomenon of repeat burglary and its significance for crime prevention, criminology and victimology. The research program for this thesis was inspired some time ago by the Kirkholt burglary prevention project in the United Kingdom. The reduction of repeat victimisation quickly came to be seen as the key to Kirkholt?s success and by the late twentieth century victim-based crime prevention projects had been implemented in many parts of the world. However, even though these projects have achieved notable success there is still intense debate about why one-time victims are more likely than others to become future victims. This thesis aims to increase understanding of repeat burglary and other forms of repeat victimisation by contributing to its key concepts and its methods of analysis, and by applying these insights in Australian settings. In pursuing this endeavour the thesis links the problems of repeat victimisation with problems in other areas of criminology and social science. In particular the issue of whether prior victimisation is a cause of future victimisation or merely a marker of pre-existing risk has analogs in the areas of offending, of employment, in international disputes, and in many others. Despite this, there has been limited transfer of methods and concepts between repeat victim researchers and researchers in other areas. The thesis examines repeat burglary as a substantive area of research, but its approaches to method, concepts and data are relevant to all repeat victimisation research. ... It draws together criminological theory, conceptual analysis, and a pioneering application of survival analysis to pursue the mechanisms underlying repeat burglary in a Perth suburb. In doing so it illuminates issues about the relative power of state dependence and heterogeneity explanations of repeat burglary and arrives at substantive results that in some aspects differ from findings in the United Kingdom. This section also argues that the concept of state dependence commonly adopted is iv unnecessarily constraining and that a broader concept can explain some potentially conflicting findings of repeat victimisation research. Section 3 is an evaluation of a victim-focused burglary prevention initiative in Adelaide one of two nationally supported pilot projects. Section 4 examines carefully the claimed advantages of victim-focused crime prevention for distributing burglary prevention resources in an efficient and equitable way. It examines evidence concerning the differential capacity and willingness of victims to take effective preventive action and the need for both individual and collective support for effective preventive initiatives. Section 5 concludes the thesis by arguing first that the merging of victim support and crime prevention is not as simple as is sometimes claimed. It also argues that crime prevention needs to take into account more than criminological theory if it is to be effective. An important argument of the conclusion is that criminological imagination has been overly limited in comprehending repeat victimisation, and it explores the ways in which criminological research still struggles to appreciate the importance of the victim for theory and crime prevention. It also argues that the implications of repeat victimisation have yet to be fully developed and accepted. Fuller details of the thesis structure are given at the end of the introduction.

An evaluation of the effectiveness of community policing forums in the Makhwibidung Village under Greater Tzaneen Municipality in Limpopo

Malatji, Madintshi Modjadji January 2016 (has links)
Thesis (M. A. (Criminology)) -- University of Limpopo, 2016 / Community Policing Forum is a forum established in terms of section 19(1) of the SAPS Act 68 of 1995 aimed at ensuring police accountability, transparency and effectiveness in the community. It was aimed at bridging the gap between the police and the community at large and builds a harmonious relationship between them. This study was aimed at evaluating the effectiveness of Community Policing Forums (CPF) in reducing crime in Makhwibidung village. Using structured and non-structured questionnaires, a total of 40 participants consisting of three groups, namely SAPS, CPF committee and residents, were conveniently selected to provide their knowledge of CPF in the above mentioned village. The findings revealed, by majority (82.50%) of respondents, identified lack of resources as the main challenge against the functioning of CPF, whilst 55% of 40 respondents pointed out poor relationship between the police and the community among other things. These challenges may therefore lead to the downfall of CPF, and thus showing that CPF still needs full support not only from the residents but from the provincial and national government. However, beside the challenges, the community and the police still manage to work jointly to fight against crime in their area as it is mandated by the Interim Constitution of 1993 that CPF must be established in each and every police station so that together they can fight crime.

Efficacy of government strategies in the prevention and control of organised crime in Limpopo Province

Mothibi, Kholofelo Annah January 2017 (has links)
Thesis (MPA.) -- University of Limpopo, 2017 / The aim of this study was to assess the effectiveness of the measures in the prevention and control of organised crime by government agencies based in Limpopo Province. The research was qualitative in nature and semi-structured interviews were conducted with 12 law enforcement officers from the DPCI, DSSL, SAPS, Home Affairs, SARS Customs and Excess, AFU, and the NPA PCLU. Data was analysed though thematic analysis. The results revealed that the government strategies in Limpopo still require concerted efforts in the prevention and control of organised crime. The government has identified measures to fight organised crime and has adopted the criminal justice response/ institutional and the legislative response to the crime. The measures taken by various units are found to be ineffective in dealing with organised crime since organised criminal networks are often flexible, dynamic, innovative and resilient. Furthermore, corrupt activities and collusions by law enforcement officers hinder the effective implementation of the strategies to control organised crime. The findings of the study show that there is coordination and communication among the law enforcement agencies such as the DPCI, SARS, Home Affairs, and the NPA PCLU, among others. This coordination is envisaged through intelligence, information sharing and interoperability. The study highlighted poor implementation of the multi-agency approach as one institution is expected to facilitate and lead the prevention of organised crime (which is the DPCI). The findings further highlight, for example, that the smuggling of illegal cigarettes is currently a challenge for the provincial government as a highly committed organised crime. The study recommends for the development, by the government, of an Organised Crime Threat Assessment in order to effectively recognise the need for responses, which should be based on a sound understanding of the nature and characteristics of the organised crime environment. In addition, it recommends for the development of an Organised Crime Response Plan to align efforts to identified critical organised crime threats. The study further recommends for the adoption, by the government, of relevant multi-agency approaches in addressing organise crime – both operational and policy or regulatory – which will underpin a whole-of-provincial government approach to organised crime. KEY WORDS: Organised Crime, Criminal, Crime Prevention, Crime Control, Effectiveness, Coordination.

An exploration of street robberies at Bungeni Village under Makhado Municipality, Limpopo Province, South Africa

Hlungwane, Hlamalani Mildred January 2021 (has links)
Thesis (M. A. (Criminology and Criminal Justice)) -- University of Limpopo, 2021 / The purpose of this study was to explore street robberies at Bungeni village, situated under Makhado Municipality of Limpopo Province, South Africa. The study sought to identify factors contributing to street robberies, to assess experiences of victims of these robberies and to determine measures that can be applied to prevent them. This qualitative study applied the exploratory research design to recruit participants using non-probability sampling techniques, specifically purposive and snowball sampling techniques. Thirteen (13) participants, including ten (10) victims of street robbery and three (3) local SAPS officials were selected for this study. Data was collected using individual face-to-face semi-structured interviews. Based on the transcribed data, themes were extracted and analysed using Thematic Content Analysis (TCA). This study established that there are factors that contribute to the occurrence of street robberies; victims are affected by street robberies (i.e. be it social, psychological and financial); and that there are measures that may reduce the occurrence of these robberies. Findings of the research indicate that factors such as time, space, individual’s lifestyle and routine activities contribute to victims being robbed in the streets and that these victims experience victimisation of street robberies differently. For recommendations, this study argues that some of these factors are lifestyle exposure, individual activities, spatial and temporal factors. Street robberies are characterised by the use of weapons, force and threat of force by offenders. Lastly, street robberies have a negative impact on victims. Keywords: Aggravated robbery, Crime prevention, Robbery, Street robbery and Victims
