Although interpersonal violence is the leading cause of nonnatural death among adolescents in South Africa, research is limited. This thesis examined homicides among adolescents (15-19 years) in the city of Johannesburg, South Africa, during the period 2001 to 2009. It aimed to describe the incidence and epidemiology; depict the situational contexts based on victim, offender and event characteristics, and to develop a situational typology of adolescent homicides; and to identify the structural factors associated with neighbourhood levels of adolescent homicide within the city. Four separate studies were conducted using data from the National Injury Mortality Surveillance System (NIMSS), police case records, and Census 2001. The results revealed an average annual homicide rate of 23.4/100 000, with firearm homicides decreasing considerably over the study period, while homicides due to sharp instruments and blunt force increased. The epidemiological results highlighted the vulnerability of male, and black and coloured adolescents. The typological analysis identified three categories of adolescent homicide, namely: 1) male victims killed by strangers during a crime-related event; 2) male victims killed by a friend/acquaintance during an argument; and 3) female victims killed by male offenders, and indicates the need for multiple and focused prevention strategies. Alcohol use was also prevalent, with 39% of the victims tested having positive blood alcohol concentrations (BAC). The characteristics found to be associated with alcohol-related homicides, specifically, male victims killed with sharp instruments in public places, over the weekends and during the evenings, and by a friend/acquaintance draw attention to both the harmful pattern of intoxication-oriented drinking and the risky situational contexts in which adolescents consume alcohol. Finally, the results also showed that the incidence of male and female adolescent homicides was greater in neighbourhoods characterised by poverty and deprivation, while female adolescent homicides were also higher in neighbourhoods marked by high concentrations of households where children were not living with their parents. Overall the results point to the urgent need for a comprehensive prevention strategy that targets adolescents, their families and communities, and also addresses weapon availability, alcohol use, and issues of masculinity and gender to reduce homicides among adolescents. / D.

Incidents, threats and vulnerabilities have the potential to negatively affect an organisation’s assets. Information on these incidents, threats and vulnerabilities are important to security. It is therefore necessary for this security information to be effectively and efficiently managed, so that correct decisions may be made on the implementation of security risk control measures. This study explored the management of security information in the security industry by undertaking the following: • establishing the “status quo” of the collection and analysis of security information and the implementation of security risk control measures in practice; • identifying the nature and extent of problems experienced in the collection and analysis of security information and the implementation of security risk control measures; and the • discovery of a new Security Information Management Model (SIMM). Mixed methods research was used to study the management of security information in the security industry. The explorative research design was used for this purpose. Semi-structured and focus group interviews were conducted with senior security managers and operational security officers, respectively. The grounded theory research design was used to analyse the qualitative data in order to generate a substantive grounded theory. The theory is that security officers operate without a standardised framework to manage security information. The data from the semi-structured and the focus group interviews were used to design a questionnaire to conduct a survey using the quantitative approach. The non-experimental research design was used to conduct this self-administered questionnaire survey. The data from this questionnaire survey helped validate and confirm the substantive grounded theory. The study found that there was the need for a Security Information Management Model to manage security information in the security industry. Based on this finding the researcher recommended a new Security Information Management Model for the management of security information in the security industry. / Criminology / D. Litt. et Phil.

Sex work is a highly debatable subject in the field of psychology but little has been said about sex work and resilience. Challenges associated with criminalisation of sex work are rife but sex work continues to exist. This study explored the ability of heterosexual street based female sex workers (FSW) to ‘bounce back’ from challenges they face. The study employed qualitative paradigm and a transcendental phenomenological design was used. Snowballing sampling was used to select twelve FSW who participated in semi structured interview. Thematic analysis was used to extract recurrent themes across participants. Participants reported being victimised and physically and verbally abused by clients and the public. FSW showed their resilience by rationalising their role with having a purpose in working as FSW, obligation as bread winners and regarding sex work as legitimate work. They adopted psychological survival techniques and used various safety techniques to cope. The results emphasised importance of employing resilience and strength based approaches in researching and developing training and psychological programmes for sex workers. / Psychology / M.A. (Psychology)

A sociological approach is used to analyze incidences of extreme opportunism in financial markets. Through an analysis of arguably the most widely publicized "rogue" trader events in recent history, a determination is made of the validity of explaining these events as aberrations, attributable to the actions of "rogues". The primary focus is the role of structural factors underlying these incidences of extreme opportunism in financial markets. A diverse range of documentary and other sources is used to avoid any form of bias as far as possible. It was found that structural factors act as countervailing forces to inhibit such behavior or as motivators and facilitators acting as catalysts for extreme opportunism. The balance between these factors largely determines the level of opportunistic behavior in a particular environment. Extreme opportunism is therefore not an aberration or "rogue" occurrence but a manageable phenomenon intrinsic to the social structural context within which it occurs. By conceptualizing these factors as countervailing forces one is forced to view structural factors, like compensation structures and formal and informal restraints, relative to one another and no longer in isolation. This realization translates into the conclusion that restraints and oversight systems for example, should be designed relative to the relevant motivators and facilitators in its area of application. In an environment where traders of highly geared financial products are motivated with multimillion USD incentive packages, a low budget oversight system and inexperienced regulatory staff, is clearly not the appropriate tools to control and manage extreme opportunism. / Criminology and Security Science / D.Phil.

In an attempt to find more information on the developing of an offender profile through docket analysis, the researcher utilised sources available in the Greater George area, as well as national and international material. The initial idea was to test the general knowledge of the concept “offender” profiling locally, in order to research and later suggest how such a profile of a rape offender could be developed through docket analysis. To establish this, it was important to indicate how offender profiling forms part of the objectives of investigation of crime. The objective – the individualisation of crime – was directly linked to profiling, as it suggests that the crime is an act of a particular person or persons. At the heart of the concept “profiling”, it is suggested that the trademarks of the offender can be deduced by carefully and painstakingly examining the characteristics of the offence. This information can, at a later stage, predict the most likely offender who could have committed the offence. When the odds are against one in the investigation of crime – more specifically, a rape case – the concept and goals of offender profiling should most definitely be considered as a key aid. / Police practice / M.

This research looks at the best practices applied by forensic investigators in conducting lifestyle audits on white collar crime suspects. The researcher explored, firstly, how a lifestyle audit relates to white collar crime investigations; secondly, the best practices in performing lifestyle audits on white collar crime suspects, and lastly, the various sources of information available to forensic investigators when conducting a lifestyle audit of a white collar crime suspect. As lifestyle audits will serve as an investigative tool in future forensic investigations into white collar crime, this study’s aim was to understand and create an awareness of the current best practices applied by forensic investigators within private sector forensic investigation practices while conducting lifestyle audits during white collar crime investigations. It also makes available research data regarding the concept of lifestyle audits in white collar crime investigations, the implementation of these audits, the benefits, and the best practices of these audits. The general purpose of this study was to provide practical recommendations on the best practices for lifestyle audits for forensic investigators within private sector. / Criminology and Security Science / M.

Secondarily the individual state rights based on legislatives standards are also reviewed in this section, in respect to effects on a citizens rights and freedoms. The following section discusses the possible psychological and ethical effects. The field investigation part was conducted by a controlled research investigations using interviews with individuals currently in police custody. The research focuses on the actual emotional experience of fear incarceration.

In this paper, the author analyzes the alleged consent, stating their stance against it and proposing, instead, the alleged will, considering that the last is right for describe the legal fiction used to recreate the moment in which the legal holder knows the fact and have the possibility of providing consent to excute the ‘ilicit’ action. In this line, the author reviewed the theories that explain the legal nature of the alleged will, rejecting it as a noncriminal behavior and considering it an autonomous underlying justification. Also, the author describes the requirements of this alleged will, differentiating it from other situations as subrogation. Finally, the author makes a review of the two categories where the alleged will occurs: performances in foreign interest and actions on self-interest. / En el presente artículo, la autora analiza la figura jurídica del consentimiento presunto, señalando su postura contraria a dicha formulación y proponiendo, en su lugar, el término voluntad presunta, por considerarlo más exacto para describir la ficción jurídica utilizada para recrear el momento en el que el titular del bien jurídico habría consentido la actuación del autor, en caso de haber conocido el hecho y de haberse encontrado en la posibilidad de brindar su consentimiento. En dicha línea, la autora repasa las teorías doctrinarias formuladas para explicar la naturaleza jurídica de la voluntad presunta, descartando que se trate de una causa de atipicidad penal y optando por considerarla una causa de justificación autónoma. Asimismo, la autora describe los requisitos que deberá tener esta voluntad presunta para ser considerada válidamente como una causa de justificación autónoma, diferenciándola de otros supuestos como la subrogación. Finalmente, la autora hace una revisión de las dos categorías donde puede presentarse la voluntad presunta: las actuaciones en interés ajeno y las actuaciones en interés propio.

This research explores whether women offenders who committed property crimes suffer from feminization of poverty, and social deprivations as asserted by the economic marginalization theory. Social deprivations include being a single parent with dependent children at home, being the main financial supporter of a household and being primary caretaker to minor children.
