The effect of mark enhancement techniques on the presumptive and confirmatory tests for blood

An investigation into the effects of physical and chemical enhancement on subsequent presumptive and confirmatory tests for human blood is presented. Human blood was deposited onto porous (white 80 gsm paper and brown envelope) and non-porous (tile and linoleum) substrates in a depletion series (30 depletions on non-porous and 20 on porous) and subjected to three ageing periods; 1, 7 and 28?days. A number of enhancement techniques were tested [fluorescence, black magnetic powder (BMP), iron-oxide black powder suspension (PS), cyanoacrylate (CA) fuming, acid violet 17 (AV17), acid yellow 7 (AY7), ninhydrin, DFO and Bluestar Forensic Magnum (BFM) luminol] to evaluate their potential effects on subsequent presumptive and confirmatory tests. AV17 and Bluestar provided the best enhancement and fully enhanced all depletions in the series. The sensitivity of the Kastle-Meyer (KM) (presumptive), Takayama and RSID-Blood tests (confirmatory) was initially investigated to determine the range of detectable depletions. The KM test detected all depletions, whereas the Takayama test detected up to depletion 6 and RSID-Blood detected up to depletion 20 (paper), 10 (envelope), 15 (tile) and 9 (lino). The abilities of these tests to detect blood after enhancement were then observed.A number of techniques resulted in little to no effect on any of the blood tests, whereas adverse effects were observed for others. Ninhydrin and CA fuming caused weak but instantaneous positive KM results whereas methanol-based AV17 and AY7 delayed the reaction by as much as 1?min. The Takayama test was not very sensitive, therefore, its performance was easily affected by enhancement and negative results were often observed. RSID-Blood tests were largely unaffected by chemical enhancement although a drop in positive results was observed for some of the techniques when compared to positive controls.Using a standard procedure for DNA extraction, all the tested blood samples (before and after enhancement) gave a detectable quantity of DNA and were successfully profiled. Out of the 45 samples processed for DNA profiling, 41 gave full profiles, while the remaining showed allele drop out in one or two loci.     

“Regulation,I presume?” said the robot – Towards an iterative regulatory process for robot governance

This article envisions an iterative regulatory process for robot governance. In the article, we argue that what lacks in robot governance is actually a backstep mechanism that can coordinate and align robot and regulatory developers. In order to solve that problem, we present a theoretical model that represents a step forward in the coordination and alignment of robot and regulatory development. Our work builds on previous literature, and explores modes of alignment and iteration towards greater closeness in the nexus between research and development (R&D) and regulatory appraisal and channeling of robotics’ development. To illustrate practical challenges and solutions, we explore different examples of (related) types of communication processes between robot developers and regulatory bodies. These examples help illuminate the lack of formalization of the policymaking process, and the loss of time and resources that the waste of knowledge generated for future robot governance instruments implies. We argue that initiatives that fail to formalize the communication process between different actors and that propose the mere creation of coordinating agencies risk being seriously ineffective. We propose an iterative regulatory process for robot governance, which combines the use of an ex ante robot impact assessment for legal/ethical appraisal, and evaluation settings as data generators, and an ex post legislative evaluation instrument that eases the revision, modification and update of the normative instrument. In all, the model breathes the concept of creating dynamic evidence-based policies that can serve as temporary benchmark for future and/or new uses or robot developments. Our contribution seeks to provide a thoughtful proposal that avoids the current mismatch between existing governmental approaches and what is needed for effective ethical/legal oversight, in the hope that this will inform the policy debate and set the scene for further research.     

Achieving zero hunger: implementing a human rights approach to food security in Ethiopia

A human rights approach to food security seeks to empower vulnerable groups to claim their rights. It also reinforces a government’s obligations to respect, protect and fulfil the right to food. Furthermore, it encourages the integration of the right to food into the design and implementation of food security policies. This article examines the human rights approach to food security, with specific reference to Ethiopia. It assesses the historical causes of Ethiopia’s food insecurity, and examines the legislative and policy measures that the country has adopted over the last three decades in order to achieve food security. Food insecurity in the country is largely explained by the absence of government accountability. In 1973 and 1984, the hunger caused by drought was transitioned to famine not because of overall unavailability of food in the country, but because the government failed to provide food aid to the starved people and concealed the occurrence of famines from the international donors. Despite designing some food security policies over the last three decades, the country has not yet adopted sufficient legislative and judicial measures to enforce the right to food. This article argues that Ethiopia should introduce a framework law on the right to food to end hunger in the context of achieving national food security.     

Using context and difference in sex offender treatment: An integrated systemic approach

Summary

The primary objective of this paper is to promote a re-examination of the current use of cognitive-behavioural programmes in work with men who have sexually offended against children or adults and to encourage the application of ideas from the systemic field. In order to support this objective, the paper puts forward and develops the following arguments:

1. That the current content of manualised programmes in this field has been distilled too far and left behind some of the most important principles of the cognitive approach. Returning to the work of Marshall et al (1999), the need for a thorough and broad-based assessment of each individual prior to deciding treatment goals is clearly recommended. Further, there is a need to pay much more attention to differences between, as well as similarities of those who sexually offend.

2. That ideas from within the systemic therapeutic field be integrated within existing approaches to attempt to address some of the limitations of cognitive-behaviour therapy as currently employed. Evidence for the potential benefits of this comes from a broad personal experience of working directly with offenders and consulting to group facilitators.

It is concluded that all therapeutic approaches reach a ‘moment of integration’ (Pinsof, 1994), when their failures are recognised and other approaches are drawn on. It is suggested that this moment may be upon us in this area.     

Poly-Victimization as a Life Condition: Correlates of Poly-Victimization among Finnish Children

According to criminological literature, victimization tends to cluster among the same adolescents. Recent American studies have shown that the poly-victimized youth are different in terms of their whole victimization profile than those children with fewer or no victimization experiences. In this article poly-victimization is studied among Finnish sixth and ninth graders (n = 13,459) based on the Finnish Child Victim Survey 2008. The article will answer questions with regard to accumulation of victimization and its associations with children's psycho-social well-being. The study examines the individual and family level background characteristics which are related to poly-victimization. The accumulations of these risk factors are analysed with poly-victimized children compared with less or non-victimized children. According to the analysis, poly-victimization exists among Finnish children and adolescents. In addition, the characteristics indicated as risk factors of victimization seem to accumulate among poly-victims. With cross-sectional data, no causal conclusions can be made, but poly-victimization is related to higher levels of psycho-social problems. The results confirm earlier findings of poly-victimization as a life condition.     

Fragile States: A Donor-serving Concept? Issues with Interpretations of Fragile Statehood in Afghanistan

Abstract

The paradox of attempting to (re)construct state institutions without considering the socio-political cohesion of societies recurs throughout the world, most notably today in the Middle East, Africa and the Balkans. This essay tries to shed some light on the debate around the concepts of state and nation-building. Drawing on a sociological understanding of the modern nation-state, it contends that it is impossible to conceive of statebuilding as a process separate from nation-building. This essay identifies two different schools of thought in the discussion concerning the statebuilding process, each of which reflects different sociological understandings of the state. The first one, an ‘institutional approach’ closely related to the Weberian conception of the state, focuses on the importance of institutional reconstruction and postulates that statebuilding activities do not necessarily require a concomitant nation-building effort. The second, a ‘legitimacy approach’ influenced by Durkheimian sociology, recognizes the need to consolidate central state institutions, but puts more emphasis on the importance of socio-political cohesion in the process. Building on this second approach and demonstrating its relevance in contemporary statebuilding, this article concludes with a discussion of recent statebuilding attempts and the ways external actors can effectively contribute to statebuilding processes.     

Citizens’ Initiatives: How Local Governments Fill their Facilitative Role

In the context of drastic cutbacks many Dutch municipalities consider citizens’ initiatives (CIs) as an attractive alternative for municipal policies aimed at improving the livability and safety in neighbourhoods, simultaneously building responsible citizenship. In this paper we combine different theoretical perspectives to analyse the institutional settings in which CIs are being realised, and how municipalities try to facilitate such initiatives. Municipalities can do this by either trying to structure the relevant networks or by various forms of process management. This analysis sheds light on how municipalities use a variety of instruments to mobilise citizens to participate in CIs. In using such instruments they can influence various factors (like motivations, personal resources, social capital and expected responsiveness; cf. Lowndes et al.’s CLEAR model) that increase the likelihood of civic engagement.     

Anti-Immigrant Parties,Local Presence and Electoral Success

Abstract

Does the local organisational presence of anti-immigrant parties affect their chances for electoral success? In order to answer this question, the article explores the potential of a supply-oriented explanation to anti-immigrant party success by examining the electoral advancements the Sweden Democrats (SD) made in the 2006 and 2010 elections. Our results indicate that traditional demand-side explanations to anti-immigrant party success can be successfully complemented by an ‘internal supply-side argument’ to make the electoral fates of these parties more intelligible. Whether the SD had a local organisational presence had a substantial effect on its results in the national election and on the probability of gaining representation in local councils. Thus, the party’s fate in the national as well as local elections was largely determined by whether or not it had a local organisational presence in Swedish municipalities.     

Local Politics Online: The Influence of Presumed Influence on Local Politicians’ Online Communication Activities in Germany

Abstract

How extensively local politicians use online media to communicate with others and the factors that influence their online activities have rarely been examined. In particular, it is unknown whether local politicians use online media more extensively when they believe that online media has a strong political influence on others. To examine this, a standardised survey among German local politicians was conducted (n = 608). The results showed the following: The stronger the politicians perceive the influence of facebook and Twitter on journalists to be, the more extensively they spread information via these social media networks. However, the presumed influences on the public or on other politicians do not affect those online activities. Thus, local politicians apparently do not pursue a disintermediation strategy – they do not try to bypass journalism by directly addressing the public. Rather, journalists seem to be an important target group for local politicians’ online communication efforts.     

Aviation security and terrorism

Abstract

The author asserts that a sophisticated sabotage threat to U.S. international civil aviation has been well known to the U.S. government and air carriers since the early 1980s. He believes that both the U.S. government and air carriers have failed to do enough to counter this sabotage threat. He cites the findings of the President's Commission on Aviation Security and Terrorism (May 1990), and the enactment of the Aviation Security Improvement Act (Nov. 1990) to support his beliefs. The author concludes by providing a recipe for corrective action.
