Teaching criminal investigation: A critical thinking approach

The purpose of this paper is to explore the “critical thinking” approach to teaching and develop those concepts into meaningful instructional activities in the classroom. The authors offer practical suggestions based on the critical thinking philosophy for implementing an active learning approach. The case study method serves as the foundation for an investigative process course and lead-up activity to the simulated preliminary and follow-up investigation. The instructor presents the critical thinking process and content information that enables students to perform five basic progressions: (1) case studies; (2) the preliminary investigation; (3) follow-up; (4) suppression hearing; and (5) moot court criminal justice simulations.     

Methods for ensuring the highest DNA concentration and yield in future and retrospective trace DNA extracts

In forensic laboratories, increased extraction efficiency of trace evidence is paramount because analytical success is intrinsically dependent on the quantity of DNA recovered. Moreover, highly concentrated nucleic acids are vital for effective downstream analysis and high quality results. This study investigated the efficiency of extraction with the Qiagen® QIAamp® DNA Investigator kit, and explored improvements to the methodology that would maximise the recovery of low concentration forensic samples. Controlled amounts of starting cellular material were used to mimic trace (or low level) DNA deposits prior to DNA extraction with the Investigator kit. Addition of the provided carrier RNA along with conducting two successive elutions of 50 µL improved the net recovery of DNA to 95%. Concentration with centrifugal filters post-extraction were able to concentrate DNA but a large net loss was observed. For the concentration of historic, retrospectively extracted DNA, centrifugal methods are able to concentrate DNA extracts previously too dilute for analysis. These concentrated volumes, however are small, allowing for minimal downstream analysis attempts before the sample is exhausted.     

Productive power in the Papua New Guinea church partnership programme

This article analyses the strategy of partnership governing the Papua New Guinea Church Partnership Program (CPP). Using a governmentality lens that sees power as having a productive aspect, it focuses on how the technologies of financial management and planning, monitoring, and evaluation (PME) are taken up by the churches. Fieldwork research reveals how, in conforming to the discipline of these technologies to fulfil the partnership requirements, skilful and pragmatic individuals utilise the same technologies to empower their churches to enact their theology on development. For partnerships to work, the space must be created for such productive power to flourish.     

Strategic planning through a participatory learning and action framework: a Kenyan study

This paper reflects on the use of a participatory learning and action (PLA) framework in a strategic planning process (SPP) at a primary school in rural Kenya. Successes and challenges are discussed, focusing on the barriers to fully implementing the PLA framework. Additionally, lessons learnt and ways forward for participatory SPPs are outlined. The PLA framework allowed the project stakeholders to engage in a planning process that gave participants a voice in the process. Although PLA methodology faces shortcomings, the application of this model is a step towards making community development more sustainable.
