Automated shape annotation for illicit tablet preparations: A contour angle based classification from digital images

In order to facilitate forensic intelligence efforts in managing large collections of physical feature data pertaining to illicit tablets, we have developed an automated shape classification method. This approach performs categorical shape annotation for the domain of illicit tablets. It is invariant to scale, rotation and translation and operates on digital images of seized tablets. The approach employs two processing levels. The first (coarse) level is being based on comparing the contour curvature space of tablet pairs. The second (fine) level is a rule based approach, implemented as a classification tree, that exploits characteristic similarities of shape categories. Annotation is demonstrated over a collection of 169 tablets selected for their diverse shapes with an accuracy of 97.6% when 19 shape categories are defined.     

Fairness matters when responding to disasters: An experimental study of government legitimacy

Governments worldwide are regularly faced with severe weather conditions and disasters caused by natural hazards. Does the way in which governments respond to disasters affect their legitimacy? The current study investigated how evaluations of authorities were influenced by four aspects of a governmental response to a hypothetical disaster. In a survey experiment participants read a scenario in which a government distributed aid in the aftermath of a flooding. Data were collected from the Netherlands, France, Poland, Ukraine, and Russia (N = 2,677). Results showed that the government was seen as more legitimate when it was described as distributing resources fairly, following fair procedures, and providing a material benefit to the participant. However, in contrast to predictions derived from system‐justification theory, results showed that outcome dependence was associated with reduced legitimacy. These findings suggest that response policies that address both instrumental and fairness concerns might help maintain positive evaluations of governments.     

Exclusivity of citizens’ initiatives: Fuel for collective action?

ABSTRACT

Self-organized citizens’ initiatives are a form of collective action and contribute to society through the production of public goods and services. Traditional collective action theory predicts that such initiatives are near impossible because of the persistent problems of free-riding. Citizens’ initiatives however do exist and function properly, and their numbers seem to be increasing in countries such as the Netherlands. This article argues that free-riding problems can be overcome when some form of exclusivity is arranged in citizens’ initiatives. We assume that citizens’ initiatives use active and/or passive strategies to limit free-riding behaviour. Using three illustrative cases, our research shows that position rules, boundary rules, and authority rules are used in a subtle and often implicit way to differentiate the level of influence and authority between the more and the less committed members, enabling collective action. Such rules, though advantageous, may be paradoxical to the goals of the citizens’ initiatives and can undermine the virtues associated with them.     

Law and order as a development issue: Land conflicts and the creation of social order in Southern Malawi

Registration of individual title to land in order to create legal security has been the central concern in the rich literature on land and law in Africa. The problem of legal insecurity is approached here from a different angle which has received relatively less attention: dispute settlement. The article results from the observation of land disputes in local political arenas. It portrays a local legal cultural universe in which legal insecurity arises especially from legal situations stressing group consensus. It appears that people who are accused of witchcraft and groups which are said not to belong are particularly vulnerable in such a legal culture. The conclusion argues that this case material reveals connections between law, land and the creation of social order which may throw light on many other situations. It pleads for more attention to be paid to the development of jurisprudence in attempts to create legal security.     

The Munsinger affair: Images of espionage and security in 1960s Canada

Using the Gerda Munsinger affair of 1966, this article explores Canadian attitudes in the 1960s concerning the nature of security threats to Canada, the proper role of government in protecting Canadian security, and espionage and spies generally. Initial findings suggest that the RCMP was out of step with much of the Canadian public in determining what constituted a legitimate security threat and that, regardless of how Munsinger herself was variously assessed as a security risk by the actors in the public inquiry or by outside observers, there clearly existed a widely shared perception of the ‘typical profile’ of the female spy which was likely heavily influenced by contemporary popular culture.     

Examining Commuters’ Cognitive Responses to Minibus Taxi Advertising

Abstract

Limited scholarly studies have been conducted on transit advertising in general, but even more so in South Africa. The purpose of the current study was to examine commuters’ cognitive responses to minibus taxi advertising by measuring their: (1) noting of minibus taxi advertising; and (2) recall of elements in minibus taxi advertisements. A survey was administered by trained fieldworkers to a quota-based sample of 398 regular minibus taxi commuters at a major taxi rank in Mbombela, Mpumalanga, South Africa. The results revealed that minibus taxi advertising has the potential to attract commuters’ attention, since the vast majority of the respondents regularly note advertisements on passing minibus taxis. The findings also revealed that some sub-groups in the sample demonstrated different cognitive responses. It was furthermore found that the commuting respondents typically recalled visual cues, colours and branding elements of minibus taxi advertising. The unique contribution of the study is that it is one of the first to examine the effectiveness of minibus taxi advertising media on a cognitive level. Thus, from an industry perspective, the study can guide marketers, advertisers and managers in grasping minibus taxi advertising in order to make more effective use of this unique out-of-home (OOH) advertising media platform for their advertising purposes.     

Resolving the tensions between the principles of aid effectiveness: an Indonesia-Australia technical assistance project

It has been more than 10 years since the Paris Declaration was signed, yet critical questions remain about whether – and how – increased compliance at the national level has improved the overall effectiveness of Official Development Assistance. Previous studies have argued fundamental tensions arise between the principles of aid effectiveness as they are translated into practice. This article explores this argument using a case study of an Australian-Indonesian technical assistance project – the Poverty Reduction Support Facility – carried out between 2010 and 2015. It demonstrates that tensions do arise between the principles of aid effectiveness as they are translated into practice, but these can be resolved through political negotiation and compromise.
