An evaluation of the MMPI-2 using South African pre-trial forensic patients prediction of criminal responsibility and assessment of personality characteristicsDu Toit, Emile January 2004 (has links)
This study examines the utility of the MMPI-2 in predicting responsibility in pre-trial forensic patients, using a post hoc sample of 94 offenders from Sterkfontein Psychiatric Hospital in Gauteng. Firstly, the overall characteristics of the pre-trial forensic patients are discussed, following an analysis of demographic, clinical, criminal and MMPI-2 pre-trial data, as well as an overview of the Megargee typological classification of offenders. The sample is classified into Criminally Responsible (CR), Diminished Criminal Responsibility (DCR) and Not Criminally Responsible (NCR), and the CR and DCR groups are collapsed (CR/DCR) for many of the analyses when comparing them to the NCR group. Secondly, the variance of variables with responsibility is discussed, after examining one-way ANOVA’s of demographic, clinical, criminal and MMPI-2 variables, as well as an overview of high point pairs. Thirdly, discriminant analyses were conducted of demographic, clinical and MMPI-2 variables. When comparing the collapsed CR/DCR group to the NCR group, psychiatric diagnosis, presence of psychosis, the MMPI-2 Pa and Es scales, as well as race and substance abuse each had unique predictive power and created a substantial discriminative equation (F (6,70) = 45.732, p <0.0005) with a successful prediction rate of 96%. Using only MMPI-2 variables to predict responsibility showed significant unique contributions for the Pa, Es, MAC-R and Mf scales, with the BIZ scale not quite significant, and a fairly significant overall discriminant equation (F (5,73) = 6.474, p < 0.0005), with an overall successful prediction rate of 82%, with the MMPI-2 variables adding an additional 3% to the predictive power of the demographic and clinical variables. Similarly, when examining the more complex 3 group responsibility classification of CR, DCR and NCR, it was found that the demographic, clinical and MMPI-2 variables of psychiatric diagnosis, psychosis, race, substance abuse, and the Pa, Es and Ma scales all had significant contributions to a powerful discriminant analysis (F (14, 136) = 19.758, p < 0.0005) that was capable of correctly reclassifying almost 95% of the sample, and the MMPI-2 variables providing an increase in predictive power of 8%. Differences in responsible and not responsible pre-trial forensic patients are discussed, as well as the role of the MMPI-2 in assessing these differences, and the fact that it is highly likely that it adds more to the forensic assessment of responsibility than a 3% (CR/DCR versus NCR) or 8% (CR versus DCR versus NCR) increase in predictive power. Limitations of the study are discussed, together with recommendations for future research with the MMPI-2 for assessment of criminal responsibility. The suggestion is made that the MMPI-2 can become a valuable tool in South African forensic settings, not only in the assessment of responsibility and malingering, but also in the placement, management, follow-up and treatment of offenders, to maximize the limited resources in South Africa allocated for the rehabilitation of offenders, and minimize the risk of recidivism or rehospitalization.

Makeshift Information Constructions: Information Flow and Undercover PoliceAksakal, Baris 08 1900 (has links)
This dissertation presents the social virtual interface (SVI) model, which was born out of a need to develop a viable model of the complex interactions, information flow and information seeking behaviors among undercover officers. The SVI model was created from a combination of various philosophies and models in the literature of information seeking, communication and philosophy. The questions this research paper answers are as follows: 1. Can we make use of models and concepts familiar to or drawn from Information Science to construct a model of undercover police work that effectively represents the large number of entities and relationships? and 2. Will undercover police officers recognize this model as realistic? This study used a descriptive qualitative research method to examine the research questions. An online survey and hard copy survey were distributed to police officers who had worked in an undercover capacity. In addition groups of officers were interviewed about their opinion of the SVI model. The data gathered was analyzed and the model was validated by the results of the survey and interviews.

Effects of Tasks on Information-Seeking Behavior in a Police Work Environment in the Context of Criminal IntelligenceTatil, Serkan 05 1900 (has links)
Although dominant effects of tasks on individuals' information-seeking behavior is accepted by many scholars, a limited number of studies has been conducted to reveal the nature of the relationship between tasks and information-seeking behavior. In their studies, some earlier researchers categorized tasks according to their complexity while others did the same according to the specifications of tasks. Two of the groundbreaking researchers in this area are Katriina Byström and Kalervo Järvelin who contributed to the understanding of the relationship between task complexity and information-seeking behavior. However, their findings also need empirical support for theory growth. In response to this need, this study attempts to test Byström and Järvelin's findings through a research using different research methods and applied in a police work environment. Other than providing empirical support for theory growth, this research is also expected to contribute to the understudied area of police information-seeking behavior. Both qualitative and quantitative data were collected from the participants who came from traffic, homicide, and anti-terrorism divisions of Ankara, Eskisehir, and Kirikkale Police Departments in Turkey. The participants identified terrorism cases as the most complex cases to solve, followed by homicide and traffic accident cases. Differences in the information-seeking behavior of three groups of police officers were examined through qualitative and quantitative data analysis. Oneway ANOVA technique and post hoc comparisons were used to analyze the quantitative data. In addition to shedding light on information-seeking behavior of police officers investigating related cases in Turkey, the results provided support for Byström and Järvelin's findings. For instance, the officers investigating more complex tasks used significantly more information sources than the others, while the use of external information sources was significantly higher in more complex cases.

The value of investigative profiling of fraud offenders by forensic investigatorsSivnarain, Ranesh 10 1900 (has links)
The problem that the researcher encountered was that forensic investigators were found not to be formally using offender profiling as an investigative technique during investigations into fraud. This research was conducted to ascertain how offender profiling may be useful in expediting the forensic investigation process.
The purpose of this research was to establish what offender profiling is, and what aspects or ingredients constitute such an offender profile. As offender profiles will serve as an aid in future forensic investigations into fraud, this study attempted to create an understanding and awareness of the value of offender profiling. In order for forensic investigators to use offender profiling during routine fraud investigations, it is extremely important that they understand the concept and its practical implementation.
The overall purpose of this study is to provide practical recommendations for the implementation and use of offender profiling to forensic investigators both in the public and private sectors. / Criminal and Procedural Law / (M.Tech. (Forensic Investigation))

Identification parade as a technique for the identification of suspects : a case study in Kwazulu-NatalNyuswa, Campbell Msizi 05 1900 (has links)
This study explores the utilisation of the identification parade as a technique for the identification of suspects. The intention of the study is to empower the investigators with knowledge they can use during their investigations. An identification parade is the most common police identification procedure. When conducted properly, it is considered more accurate than other methods.
Crime in South Africa is a serious concern and it impacts negatively on many lives. The fear of crime, the loss of life and the socioeconomic impact of crime, etc., create the impression that the battle against crime has been lost. The limited knowledge among the police investigators contributes to making the reduction of crime more difficult to achieve.
This study aims to develop good practice by recommending new ideas on how identification parades should be conducted with the view to enhancing the performance of police investigators. / M.Tech. (Forensic Investigation))

A critical analysis of the procedures followed to conduct identification parades : a case study in Mpumalanga, South AfricaMokonyama, William Madimetja 04 1900 (has links)
The research attempts to establish how an identification parade
should be conducted, for evidence derived from it to be admissible in court. To conduct effective investigation, it is important for investigators to be familiar with the concept “identification parade”, its purpose, the procedures to conduct it and its values.
To achieve the goals and objectives of the practice of an identification parade, investigators must know how to conduct it, what the value of its evidence is, and how to use it as a technique to identify suspects.
The direction, by implication, and clarification of the crime situation, is hardly possible without the determination of the identity of the perpetrator or suspect of a criminal act. The recognition of the identification parade as a form of evidence gathered is of the utmost importance. / Criminology / Thesis (M.Tech. (Forensic Investigation))

Personal description : an investigation technique to identify suspectsSefanyetso, Justice Thabang 11 1900 (has links)
This study investigates the use of personal description as an investigation technique to identify suspects. The study entails qualitative data obtained from interviews with investigators, literature, as well as case studies. The study found that personal description can be used as an investigation technique to identify suspects.
There are eight techniques that the investigator should apply in order to identify suspects or perpetrators of a criminal act. To conduct effective investigation, it is important for the criminal investigators to be familiar with the techniques of identification and the application thereof.
The description of offenders plays an important role as far as arresting offenders is concerned. The methods used - or to be used - by investigators to describe a person were also discussed. It is important that the investigators should work with other government departments, private investigators and security officials, to implement this technique in order to identify and arrest offenders. / Police Practice / (M.

Search and seizure of documents in the investigation of tax-related casesMudaly, Lindsay 09 1900 (has links)
The goal of this research was to determine the procedures used for conducting a
search and seizure in a tax-related offence in terms of the Criminal Procedure Act,
Act 51 of 1977. Aspects that cause problems for the South African Revenue Service
(SARS) investigators are the application for a search warrant and the activities that
take place before, during and after the search and seizure.
An introduction, definition and explanation are given of certain key concepts such as
forensic and criminal investigations, as well as their objectives and purpose. The
various search methods are also discussed and explained as are the chain of
custody and evidence in general.
A large part of this research deals with the legal requirements for a search and
seizure in a tax-related offence and encompasses issues such as the procedures for
obtaining a search warrant, pre-raid briefing, conducting the search, and the seizing
of, marking, storage and disposal of documents.
The findings of the research are discussed and recommendations subsequently
made regarding the shortcomings identified. The findings that were made related to
the process and procedure to obtain a search warrant, the actual execution of a
search and seizure and the legislation that authorises searches and seizures in taxrelated
offences. Further findings were made in respect of the mandate of SARS
criminal investigators to investigate, the admissibility of evidence obtained from a
search and seizure and the marking, recording, storage and disposal of seized
items. Recommendations were made regarding training, improved communication
and skills transfer to address the shortcomings identified. / Police Practice / (M.Tech. (Forensic investigation))
