A significant increase in financial crime globally emphasises the importance of forensic interviewing to obtain useful and reliable information as part of a commercial forensic investigation. Previous research has identified two interviewing strategies that are aligned with the legal framework in South Africa: the PEACE model (P = preparation and planning; E = engage and explain; A = account, clarify and challenge; C = closure; E = evaluation) and the person-centred approach (PCA). The purpose of this paper is to explore the theoretical underpinnings and application of the PEACE model and the PCA as commercial investigative strategies aligned with the legal context in South Africa.

A scoping review was undertaken to identify literature relevant to the theoretical assumptions and application of the PEACE model and the PCA.

Literature for the most part reports on the PEACE model but offers very little information about the PCA. A critical analysis revealed that the PEACE model incorporates a clear guiding structure for eliciting information but lacks content needed to create an optimal interpersonal context. To promote this, the PCA proposes that interviewers demonstrate three relational variables: empathy, congruence and unconditional positive regard. The PCA suggests a basic structure for interviewing (beginning, middle and end), while providing very little guidance on how to structure the forensic interview and what information is to be elicited in each phase.

Combining the PEACE model and PCA presents an integrated interviewing technique best suited for obtaining useful and reliable information admissible in a South African court of law. The PEACE model has a clear structure, and the PCA assists in creating an optimal interpersonal context to obtain information in an interview.

Previous research has indicated that trusts are used to commit various economic crimes, but limited studies examine the exact method of how trusts are abused. This paper aims to determine how trusts are abused to conceal assets in insolvency and divorce proceedings. Apart from discussing how fraudulent trusts are evaluated by South African courts, two court cases will also be analysed to determine how trusts have been abused in the past to conceal assets in insolvency and divorce proceedings.

The methodology used is a literature study, predominantly using court cases and relevant statutes as the primary sources of information. The difference between a sham and alter ego trust is discussed, whereafter two court cases are dissected to identify how trusts have been abused to conceal assets.

The study found that trusts can be abused in different ways to conceal assets in insolvency and divorce proceedings. This can vary from the way the trust is established to the way the trust is used. But trusts are particularly susceptible to abuse when there is no separation between the ownership and enjoyment of trust assets, and the trust lacks independent trustees.

The research finding can be used to better understand how trusts are abused in divorce and insolvency proceedings.

Given the tumultuous history of policing in South Africa, the historic relationship between the police and the public, and the continuous rising crime rates, it is perplexing that little quantitative research has been conducted on legitimacy and the SAPS. The current study assesses public confidence in police in South Africa by analyzing data from a more than three-decade-old public opinion survey. The purpose of this paper is twofold: first, to examine changes in public confidence since 1981; and second, to determine factors that cause variations in confidence during a given period.

To achieve the objectives, the authors analyzed longitudinal data collected from 1981 to 2014 as part of the world Value Survey program. ANOVA and multivariate regression analyses were conducted.

Findings indicate that confidence in SAPS was highest during the period immediately after apartheid and then dwindled from 1999 onwards. Moreover, race, happiness and education have historically influenced public confidence in the police.

These findings provide information that could be useful for transforming the SAPS, especially in developing viable strategies to strengthen the police’s relationship with citizens. Additionally, the manuscript provides an original contribution to the study of public attitudes toward the police and police legitimacy, especially in a non-western society.

An increase in outsourcing of consultancy services has been observed during procurement and delivery of public-sector infrastructure projects. However, the incidence of project failure has continued unabated despite this shift by public-sector entities. Also, there appears to be limited literature focussed on seeking to provide the rationale governing the decision to outsource or insource consultancy services by public-sector organisations. The purpose of this study was to appraise the performance of public-sector projects in which consultancy services have been outsourced or insourced. These are the gaps which this study was undertaken to fill.

A grounded theory methodology (GTM) research design was adopted based on the nature of evidence sought and gathered from a Provincial Department of Public Works and Infrastructure (PDPWI) in South Africa. Data was obtained from a mixture of semi-structured interviews and project-specific documents spanning a five-year period and was analysed according to the procedures associated with GTM. Accordingly, open coding, axial coding and pattern matching were carried out at several intervals to develop categories and themes.

The findings of the study showed the absence of a structured approach within the PDPWI for facilitating decisions pertaining to outsourcing or insourcing consultancy services within construction projects. Furthermore, the study established that both approaches yielded similar results across all performance facets of cost, time and quality. In addition, a detailed insight into the steps required for the successful application of GTM in built environment research has been provided in the study.

Limited studies have been undertaken to compare the impact of either outsourced or insourced services on the organisational and project performance. This was the gap to which the study reported in this paper was undertaken to contribute.

The purpose of this paper is to identify and evaluate the potential cooling contribution provided by a phase change material cooling vest as part of the total heat exchange mechanism of the body and take in to account the negative side effects of wearing the cooling garments.

In this study, the three-part system of body-garment-environment has been simulated through the finite element method and the problem of heat exchange between these three parts has been solved with the help of computer modeling.

The results of this modeling showed that a large percentage of the cooling efficiency of cooling vest was neutralized by the negative effects of the vest that are weight, lack of breathability, and the effects on the thermal conductivity of the skin. Therefore, the net efficiency of the cooling vests resulted in a lower decrease in skin temperature compared to the state that the negative side effects were not included in the model.

Cooling power obtained with the help of cooling garments have been studied in previous studies using either human tests or manikins. But, what has been addressed less in previous studies relates to the negative effects of such equipment on the comfort of body, along with their cooling effect. So it is the first time witch the effect of side effects of such equipments are studied. Also modeling the real performance of cooling garments have not been done yet.
