The suitability of visual taphonomic methods for digital photographs: An experimental approach with pig carcasses in a tropical climate

In the context of increased scrutiny of the methods in forensic sciences, it is essential to ensure that the approaches used in forensic taphonomy to measure decomposition and estimate the postmortem interval are underpinned by robust evidence-based data. Digital photographs are an important source of documentation in forensic taphonomic investigations but the suitability of the current approaches for photographs, rather than real-time remains, is poorly studied which can undermine accurate forensic conclusions. The present study aimed to investigate the suitability of 2D colour digital photographs for evaluating decomposition of exposed human analogues (Sus scrofa domesticus) in a tropical savanna environment (Hawaii), using two published scoring methods; Megyesi et al., 2005 and Keough et al., 2017. It was found that there were significant differences between the real-time and photograph decomposition scores when the Megyesi et al. method was used. However, the Keough et al. method applied to photographs reflected real-time decomposition more closely and thus appears more suitable to evaluate pig decomposition from 2D photographs. The findings indicate that the type of scoring method used has a significant impact on the ability to accurately evaluate the decomposition of exposed pig carcasses from photographs. It was further identified that photographic taphonomic analysis can reach high inter-observer reproducibility. These novel findings are of significant importance for the forensic sciences as they highlight the potential for high quality photograph coverage to provide useful complementary information for the forensic taphonomic investigation. New recommendations to develop robust transparent approaches adapted to photographs in forensic taphonomy are suggested based on these findings.     

‘The Sky is Falling!’ – Responses to the ‘Going Dark’ problem

The shared concern expressed in the two quotes below is that modern technologies provide criminals with a capability to evade investigation. This comment piece examines some of the policy and legal options available to governments and law enforcement agencies to try to address this concern. While accepting the claim that this phenomenon represents a real challenge to law enforcement agencies, we currently have insufficient evidence to show the true extent of the problem. What this piece does not accept is the implication contained in the quotes, and often made explicit by others, that the use of encryption represents a fundamental and irreversible shift in the balance of power between criminals and their investigators from what previously prevailed. Such claims tend to lack historical perspective, which is one of the themes of this 200th issue of Computer Law and Security Review.     

Law enforcement access to personal data originally collected by private parties: Missing data subjects' safeguards in directive 2016/680?

Access by law enforcement authorities to personal data initially collected by private parties for commercial or operational purposes is very common, as shown by the transparency reports of new technology companies on law enforcement requests. From a data protection perspective, the scenario of law enforcement access is not necessarily well taken into account. The adoption of the new data protection framework offers the opportunity to assess whether the new ‘police’ Directive, which regulates the processing of personal data for law enforcement purposes, offers sufficient safeguards to individuals. To make this assessment, provisions contained in Directive 2016/680 are tested against the standards established by the ECJ in Digital Rights Ireland and Tele2 Sverige on the retention of data and their further access and use by police authorities. The analysis reveals that Directive 2016/680 does not contain the safeguards identified in the case law. The paper further assesses the role and efficiency of the principle of purpose limitation as a safeguard against repurposing in a law enforcement context. Last, solutions to overcome the shortcomings of Directive 2016/680 are examined in conclusion.

A new method for the recovery and evidential comparison of footwear impressions using 3D structured light scanning

Footwear impressions are one of the most common forms of evidence to be found at a crime scene, and can potentially offer the investigator a wealth of intelligence. Our aim is to highlight a new and improved technique for the recovery of footwear impressions, using three-dimensional structured light scanning. Results from this preliminary study demonstrate that this new approach is non-destructive, safe to use and is fast, reliable and accurate. Further, since this is a digital method, there is also the option of digital comparison between items of footwear and footwear impressions, and an increased ability to share recovered footwear impressions between forensic staff thus speeding up the investigation.     

Science and Technology and the President's Crime Commission

The U.S. President's Commission on Law Enforcement and Administration of Justice added a Task Force on Science and Technology as somewhat of an afterthought because there had then been very little interaction between science and technology and the criminal justice system (CJS). The task force focused on the CJS as a whole and interactions among its parts, with an important emphasis on analysis of the operating systems and on the important potential role of information systems as the technology advanced. The potential applications of contemporary information and electronic technologies is considerable, especially for assessing risk and needs of identified offenders and for providing relevant information wherever needed. There is urgent need for scientific evaluation of many of the positive and negative aspects of the operation of the CJS and of the potential for new technologies.

Critical theory and the capitalist state

This article is an overview of Michel Callon's contribution to the reformulation of economic sociology and anthropology. It contextualizes Callon's concepts within science and technology studies, and indicates the main lines of influence on his thinking about economic processes. Callon's work also opens up a number of debates and challenges to current perspectives within economic sociology. Finally, the article considers the way in which Callon's perspective reconfigures both the relation of politics and economics, and the nature of politics itself.     

African research and development surveys: Highlights from the South African success story

ABSTRACT

Science and technology have a major role to play in current and future developments on the African continent as a whole. With the vast array of developmental challenges, current thinking needs to be expanded, so that technologies provide increased and enhanced solutions, such that African scientists produce an African response to the very many shared challenges affecting Africa – both as individual nations and as regards African people collectively. Key to developing an integrated science and technology network, within and across nations, is firstly to understand the extent of research and development (R&D) currently undertaken within individual territories and on the continent as a whole. In light of this, the article examines the value and importance of national surveys of research and experimental development undertaken in Africa. Within the Southern Africa Development Community (SADC), many member states now have dedicated departments overseeing state science and technology (S&T) development initiatives. South Africa has the most developed science and technology system on the continent. In recent years, other SADC countries like Mozambique, Botswana and Namibia have initiated projects to measure R&D activities within their territories. Despite this, further North, R&D measurement on the continent is uncommon, both as a result and as a cause of underdevelopment.

The article explores the limited data from selected African R&D surveys in an attempt to understand measurement issues that exist and to detail the value and importance of mapping S&T systems and their applications to developmental issues in Africa. In countries like Algeria, Angola, Burkina Faso, Cameroon, Egypt, Ethiopia, Gabon, Ghana, Kenya, Lesotho, Malawi, Mali, Nigeria, Senegal, Tanzania, Uganda and Zambia, where S&T systems exist, effective means of measurement need to be established, so that the power of these systems can be harnessed, shared and exploited to benefit the African people. To this end, the African Science, Technology and Innovation Indicators (ASTII) initiative was set up at a meeting in Addis Ababa with the aim of delivering a survey of these countries’ R&D output and potential. This is eagerly awaited by the African S&T community.

At the forefront of African R&D measurement is the South African national R&D survey, administered by the Human Sciences Research Council (HSRC). Being an established survey, the South African team is often called upon by other African nations to support the setting up of surveys. The HSRC also trains visiting African scientists in the delivery of accurate and reliable R&D survey data. This article will, for the first time, present detailed results of the most recent South African national R&D survey (2008/2009), together with a trend analysis of historic South African R&D surveys.     

“SMART” Photovoice agricultural consultation: increasing Rwandan women farmers' active participation in development

Through two case studies, this paper evaluates the value of the feminist visual methodology Photovoice as an interactive consultation tool with rural Rwandan women working in agriculture. This exploratory study suggests that it is possible, through an adapted Photovoice process, to engage and empower women in the production of information about what is most relevant to them, and reach and engage practitioners and officials through an exhibition of participants' photographs and captions. This confirmation of Photovoice's applicability with rural women in the generation of information that captures the attention of stakeholders demonstrates its potential for reproducibility in other development contexts.

Consultation agricole Photovoice « SMART » : accroître la participation active des agricultrices rwandaises au développement

À travers deux études de cas, cet article évalue la valeur de la méthodologie visuelle féministe Photovoice comme outil interactif de consultation avec des rwandaises rurales travaillant dans l'agriculture.
